The large amount of flash memory is useful for buffering

The large amount of flash memory is useful for buffering Paclitaxel microtubule collected data, as described below.In order to monitor oar motion we examined the feasibility of designing an accelerometer-based Inhibitors,Modulators,Libraries sensor that uses only accelerometers to compute the linear and angular motions of a rigid body. The main motivation for developing a gyroscope-free system was that low-cost gyroscopes lack the accuracy needed for precise oars monitoring [7]. Moreover, low cost gyroscopes (automotive applications) cost about an order of magnitude more with respect of 3 axis accelerometers. In addition, it was reported in [8, 9] that due to challenges associated with gyroscopes hardware integration, the levels of precision required for our problem cannot be achieved in the near future with inexpensive gyroscopes.

For the later reasons, Inhibitors,Modulators,Libraries we were limited to use accelerometers by our prime design constrain which was minimize sensors cost. In theory, a minimum of six accelerometers is required for a complete description of a 3D rigid body motion [10, 11]. The key to a solution of the feasibility problem is the choice of location and orientation of the accelerometers. In our case a feasible cube configuration of six accelerometers is then considered (Figure 2), and based on this configuration, a basic algorithm to subtract rotation and translation was developed.Figure 2.Diagram of the accelerometers position.To adapt two MEMS (Micro Electro Mechanical System) accelerometers to the required geometry without jeopardizing system flexibility, two Inhibitors,Modulators,Libraries sensor boards for each sensor node, as presented in Figure 3, were developed.

Each board was equipped with a LIS3L02AS4 Inhibitors,Modulators,Libraries [12] MEMS low-power three axes linear accelerometer.Figure 3.Developed PCB plugged to telosb.The LIS3L02AS4 has a user selectable full scale range of ��2g, ��6g and it is capable of measuring accelerations over a bandwidth of 1.5KHz for all axes. It features a signal conditioning, Entinostat a 1 pole low pass filter at 100 Hz, and temperature compensation. It has an analog output which is sampled using the microcontrollers embedded 12 bit AD converter. The power consumption of the LIS3L02AS4 is less than 0.85 mW [12].A single sensor node consisted of the sensor board, the interface board and battery holder with two AA batteries, all of which were housed inside a cylindrical PVC tube weatherproof and watertight, as presented in Figure 4, which was adapted to the inside oar end.

Figure 4.Mounting the mote inside the oar.The boat sensor node was also equipped with a two single three axis accelerometer selleck chemical Nutlin-3a to track vertical and horizontal motion of the boat. The difference among oar and boat sensors was the packaging. In that case, a waterproof case to keep the sensor dry from water splashing replaced the cylindrical packaging used for the oar sensors. As a base station we used a telosb mote connected to a laptop which could be used in the same boat or in the accompanying boat.3.2.

Section 5 presents the experimental data and the obtained results. Finally, the conclusions and future trends mentioned in Section 6 complete sellekchem the paper.2.?Sensor Inhibitors,Modulators,Libraries FDI in Small Autonomous HelicoptersSeveral small autonomous helicopter prototypes have been developed in recent years at different research centers throughout the world [1]. Autonomous helicopter flight requires precise position and attitude information for control and stabilization. Inhibitors,Modulators,Libraries Small autonomous helicopters carry a pack of sensors that in a typical case includes an inertial measurement unit (IMU) with three gyros, three accelerometers and a 3-axis magnetometer for attitude determination, a centimeter-precision kinematic DGPS and an ultrasonic or barometric altitude sensor for take-off and landing.

A fault in one of the sensors, if undetected, may induce position and Inhibitors,Modulators,Libraries attitude estimation errors. Reconfiguration in these cases usually consists in isolating the faulty sensor and using the other sensors to get the best estimation of position and attitude.2.1. Inertial, magnetometer and altitude sensor faultsUsual UAV sensor faults are additive (sensor output has a drift term added), multiplicative (sensor output is scaled by a multiplicative term) or ��stuck�� output (sensor output remains fixed at a constant value). The presence of these faults can be detected in most cases by means of the so-called residuals, i.e., quantities that are over-sensitive to the malfunctions. Observer-based and parameter estimation are the most frequently applied methods for residual generation in FDI [9].

Most published work in recent years on FDI systems for autonomous vehicles also use observer-based methods. Neural networks have also been used to detect sensor and actuator faults in aircrafts [10] and UAVs [4,11].The FDI system Inhibitors,Modulators,Libraries implemented in individual helicopters is described in detail in [5]. The structure of the sensor FDI Batimastat system is based on a bank of output estimators as shown in Figure 1. The number of these estimators is equal to the number of system outputs. A residual is generated for each sensor, comparing the estimator output with the sensor output. Each residual is not affected by the other sensors, and therefore fault identification is straightforward: each residual is only sensitive to a single helicopter sensor.Figure 1.Bank of estimators for output residual generation.

The FDI system with the above structure has been implemented using ARX input-output estimators. click this A number of ARX Multi-Input Single-Output (MISO) models have been identified from input-output data. These models are of the type:yi*(t)=��j=1n��i,j yi*(t?j)+��j=1r��k=1n��i,j,kuj*(t?k)+��i(t)(1)The number of identified MISO ARX models is equal to the number m of the output variables. The model order n and the parameters ��i,j an? ��i,j,k with i = 1, ��, m, of the model have to be determined by the identification approach. The term ��i(t) takes into account the modeling error, which is due to process noises, parameter variations, etc.

In the shark gill, which is the main acid-base sensing organ of t

In the shark gill, which is the main acid-base sensing organ of this scientific study ancient vertebrate, alkalotic stress induces a sAC- and CA-dependent translocation of V-ATPase into the basolateral membrane of the gill. The V-ATPase then pumps protons back into the body to counter the systemic alkalosis. Additionally, sAC forms a complex with the V-ATPase in acid-base transporting intercalated cells in mammalian kidney [103], and sAC, CA and V-ATPase are postulated to mediate proton secretion from acid (A-type) secreting cells into the renal collecting duct [104]. Thus, sAC, CA and V-ATPase seem to form a functional unit for sensing, Inhibitors,Modulators,Libraries and responding to, alterations in pH [105]. Interestingly, the sAC-CA-V-ATPase mechanism is capable of moving the proton transporter to wherever it is needed; i.e.

, Inhibitors,Modulators,Libraries the V-ATPase translocates to the apical membranes in clear cells of the epididymis and A-type cells of the renal collecting duct while it moves to the basolateral membrane in the shark gill. Because sAC, CA, and V-ATPase are evolutionarily ancient, Inhibitors,Modulators,Libraries it is tempting to hypothesize that this functional unit for sensing pH and moving protons to correct pH imbalances will be found widely utilized throughout biology.3.3. CO2 Regulation of Beating Frequency of Cilia on Airway EpitheliaAirway epithelial cells express motile cilia that are important for innate host defense; the beat of the cilia removes the mucous layer clearing toxins, pathogens, allergens, and debris Inhibitors,Modulators,Libraries [106]. To accomplish this feat, cilia beat faster during exhalation relative to inhalation. Exhaled breath has higher CO2 than inspired air.

sAC ��senses�� this elevated CO2, and sAC-generated cAMP activates PKA which increases the frequency of ciliary beating during exhalation [43]. This represents an Anacetrapib example where sAC-generated cAMP acts as a pathway modulator; CO2 chemosensing via sAC controls the rate of ciliary beating, not whether or not the cilia beat.3.4. Krebs Cycle Generated CO2 Regulates the Rate of Oxidative PhosphorylationsAC resides inside mitochondria [9,15,107] where it coordinates the rate of ATP production via oxidative phosphorylation (OXPHOS) with nutritional availability. Mitochondrial sAC activity is stimulated by Krebs Cycle-generated CO2 in a carbonic anhydrase dependent manner [15]. CO2/HCO3? stimulation of sAC activates intramitochondrial PKA which phosphorylates Complex IV of the electron transport chain, increasing its rate and capacity to handle electrons.

Because the electrons feeding the electron transport chain also originate from the Krebs Cycle, this mitochondrial CO2-sAC-cAMP-PKA pathway couples nutrient utilization (i.e., Krebs Cycle activity) to ATP production. Once again, this pathway does not turn on or off the electron transport chain, it simply selleck Brefeldin A modulates
Glucose transporter 4 (GLUT4), the main glucose transporter activated by insulin in skeletal muscle cells and adipocytes, plays a key role in maintaining whole body glucose homeostasis [1�C3].

In particular, LDPC codes exhibit an asymptotically better perfor

In particular, LDPC codes exhibit an asymptotically better performance than turbo codes and admit a wide range of trade-offs between performance the following site and decoding complexity [13]. Sartipi and Fekri [14] compare the performance of the LDPC codes and the Reed Solomon (RS) codes [15]. From the recent works, it is known that LDPC codes are attractive in WSNs because of their applications in compression, joint sourcechannel coding and distributed source coding [14,16]. However, to the best knowledge of the authors, there has been no document on the implementation of LDPC encoder/decoder in a wireless sensor node using cooperative communication. More precisely, none of the recent works have addressed the problem of reducing the energy consumption using error control coding.
In this paper, LDPC code is incorporated in cooperative communication as an error control code. Later the idea is compared with SISO communication. In Section 2, the system model is shown and the error correction using LDPC code is analyzed in Section 3. Section 4 shows the energy model for both cooperative MIMO and SISO considering error correction codes. In Section 5, simulation results are shown and discussed. Finally, Section 6 concludes the paper.2.?Cooperative MIMO Communication2.1. System ModelThe system model for C-MIMO communication is a centralized wireless sensor network where there is a data gathering node (DGN) and several clusters with several sensors in each cluster. Sensors in one cluster transmit the data to the sensors in adjacent cluster and step by step the data reach the DGN.
Figure 1 shows the cluster to cluster communication where two clusters are shown. The system considers Nt number of sensors in the transmitting cluster, Nr number of sensors in the receiving cluster and one antenna is placed at one sensor. Also, each element in the channel matrix H is assumed to be a zero-mean circularly symmetric complex Gaussian random variable with unit variance and can be considered as follows.H=(h11h12��h1Nrh21h22��h2Nr????hNt1hNt2��hNtNr).Figure 1.System model for cluster to cluster communication in wireless sensor network.The problem here is stated from the receiver point of view, so a loss model is used to estimate the received energy. To calculate the total energy consumption, both the circuit and transmitter power are taken into count. The same transmitter and receiver blocks shown in [4] are used in this paper. Source coding, pulse shaping, and modulation block are as well omitted from the design. Throughout the paper, a system with narrowband, frequency-flat Rayleigh Batimastat fading channels and perfectly synchronized transmission/reception between wireless sensor nodes is assumed. The fading is assumed constant during the transmission of each frame.

A significant color change and fluorescence enhancement can be ob

A significant color change and fluorescence enhancement can be observed in response to Cys (Figure 1). In the case of Hcy, because it has an additional methylene group in its side chain, a kinetically less favored 8-membered ring would form. As for GSH, selleck compound 1,4-addition of thiols to the ��,��-unsaturated carbonyl moieties of 4 can occur readily; however, the ensuing intramolecular cyclization similar to that of Cys cannot proceed without the presence of surfactant. No significant color formation or fluorescence response is seen in the case of Hcy or GSH under these conditions.Figure 1.Spectral response of 4 towards various thiols. (a) Absorption spectra of 4 (2.5 ��M) upon addition of thiols (2 equiv) in phosphate buffer (pH 7.4, 50 mM) at 20 min; (b) Fluorescence spectra of 4 (2.
5 ��M) upon addition of thiols (2 equiv) …Scheme 3.Proposed mechanism for the intrinsic response of 4 towards Cys.The time course of the fluorescence assay is shown in Figure 1(b). It can be seen that the fluorescence upon reaction with Cys increases with time and reaches a plateau after about 90 min, whereas for Hcy and GSH the reactions are significantly slower. The sensitivity and linearity of the response of 4 towards Cys was also investigated. Linear response with submicromolar sensitivity was observed (See Figure S5 in the Electronic Supplementary Information). The reaction products between 4 and thiols were further studied using HRMS (See Figures S6 and S7 in the Electronic Supplementary Information).3.2. Surfactant Mediated Modification of the Intrinsic SelectivityInclusion of surfactants (see Figure 2) dramatically alters the intrinsic selectivity of 4.
For example, solutions of GSH, Cys and Hcy (2 equiv) with the resorufin-acrylate probe 4 in pH 7.4 phosphate buffer generate the characteristic strong pink color immediately upon addition of CTAB only in the presence of GSH (Figure 3(a)). Other amino acids, such as Hcy and Cys, did not exhibit significant changes under the same conditions. This interesting feature indicates that 4-CTAB system can serve as a selective visual inspection dosimeter for GSH. Corresponding fluorescence increases were also observed (Figure 3(b)). Fluorescence upon reaction with GSH reaches a plateau in less than 2 min.Figure 2.Structures of surfactants employed.Figure 3.Surfactant-mediated responses of solutions Cilengitide containing 4-CTAB towards various thiols at pH 7.

36 mm. The number of capillaries and the total capacity of the integrated capillaries are summarized in Table 1. Our fluidic chip was they designed for single-use. The vertical capillary tubes function as a passive pump and a waste reservoir. Therefore, there is no outlet on our fluidic chip.Table 1.Geometric parameters of integrated capillary tubes and total flow volumes. The designed radius and center distance were 0.1 and 0.36 mm, respectively. The flow volume is the calculated value.The flow channel was fabricated from double-sided adhesive film and using a mechanical cutting plotter (CG60ST Mimaki Engineering Co., Ltd., Japan). The center flow channel (0.9 mm wide) branched to the left and right compartments (See
Color is defined as the visible electromagnetic spectrum reflected by an object and perceivable by a sensor within its detection range, being one of the most important attributes of objects’ appearance.
Being a highly informative variable, trials for its quantification by measurement (i.e., colorimetry) have conducted since the early 1900s. In fact, the first colorimetric standard CIE L*a*b* was developed in 1931 on the basis of measures under variable daylight, object and human perceptor (i.e., the tristimulus approach) [1,2]. Following the technological evolution together with the development of the Information Communication Technology (ICT), the introduction of the digital imaging widened both the acquisition tools and the rendering media, requiring the elaboration of up-to-date and different color spaces [2,3].
In this new instrumental and applicative context, there was the need to numerically define the colors by their coordinates in n-dimensional space. Although the spectrum is continuous with no clear boundaries between one color and the next ones, AV-951 color ranges were established as an approximation for coordinate definition [4].Each color depends on the type of emission source that irradiates an object, as well as on the physical properties of the object itself (which reflects the radiation consequently detected by the sensor), and finally on the in-between medium (e.g., air or water) [5]. Generally, the color spaces applied in product classification are the standard RGB (sRGB; red, green, blue) and L*a*b*. sRGB can be obtained rapidly using computer vision systems. Outputs signals are generated by the camera sensors (e.g.
, CCD or CMOS), but the rendering is device-dependent, since the range of colors varies according to the display device specifications [2,6,7]. In order to overcome this problem, sRGB values are often transformed selleck chemical Ruxolitinib to other color spaces such L*a*b*. Moreover, even the result of such transformation is device-dependent [8].Commonly other sRGB color calibrations, using various methods and algorithms, are used to overcome this problem.

To verify this we

To verify this we Imatinib Mesylate have plotted the fields for the cross-section of the ellipse in the source plane as well as a vertical cross-section along the extent of the ellipse model. The electric field plots are shown in Figures 5 and and6.6. From these figures it can be seen that the field magnitude inside the model is less than ?100 dB and the main source of energy transfer is along the surface of the trunk in the form of a creeping wave.Figure 5.Electric field distribution in the source plane.Figure 6.Electric field distribution on a vertical cut plane bisecting the cylindrical model.In Figures 7�C9 the path loss is plotted versus the distance around the elliptical model in each of the different observation planes.
As shown in Figure 7, which depicts the observations made in the source plane, the attenuation at higher frequencies exhibit a clear monotonic behavior and is characteristic of a creeping wave. The results in Figures 7�C9 have been found to agree closely with those in the literature for other body models [1,2,7,9�C19]. These results can be useful as reference points when approximating the rate of attenuation along the trunk in body-centric network scenarios.Figure 7.Path loss versus separation distance with receiving antenna at the source plane.Figure 9.Path loss versus separation distance with receiving antenna 400 mm above the source plane.3.?Numerical Phantoms for BANsAlthough simplified geometries have their use in analyzing body-centric communication networks, the availability of realistic human body models enables us to use a more rigorous approach to understand how the irregular shape of the body affects the performance of BANs.
One of the most commonly used body models is shown in Figure 10, where the original data set is comprised of voxels (i.e., 3D matrix data set). Furthermore, a hypothetical BAN configuration is shown with the transmitting and receiving antennas. To reduce the computational resources needed in the simulation, a lossy homogeneous model was used.Figure 10.Numerical human body phantom based on 3D CT scan voxel set with transmitting and receiving antennas in typical BAN scenario.Additionally, the resolution of the original voxel data set, which is 1 mm �� 1 mm �� 1 mm, was down-sampled to 3 mm �� 3 mm �� 3 mm. Even at this lower resolution the computational resources needed are high, specifically 8 hours on 16 Pentium 4 CPUs.

Research on label-free guided-mode resonant (GMR) optical biosensors has recently attracted great interest owing to Cilengitide applications for detecting Tofacitinib Citrate 540737-29-9 a variety of bio-molecular complexes such as oligonucleotides, antibody-antigens, and enzyme-substrate interactions. A GMR optical biosensor comprised of a surface relief sub-wavelength grating is designed to reflect only a single wavelength while illuminated with white light [1].

The used memory data structure allows for a reduced search comple

The used memory data structure allows for a reduced search complexity of O(1), which combined with a Finite State Automata (FSA) allows us to demonstrate that our technique effectively distributes the robots over the environment and allows them to quickly accomplish their mission. This results in a hybrid approach capable of fast, simple and computational efficient exploration. A series of simulated experiments were performed and analyzed, demonstrating the successful exploration of a 200 m2 area in about a minute with a team of three Pioneer-3DX robots at moderate driving and steering speeds and equipped essentially with a laser scanner. Additionally, successful results were demonstrated in real experiments with a team of two Jaguar V2 robots, also equipped with laser scanners, in a 20 m2 area geometrically similar to the simulation scenario.
One of the most interesting observations is that we achieved qualitatively similar navigation and robot distribution as in the literature but with a way simpler approach, using less computational power, and without any negotiation or mapping technique, at the only cost of sufficient localization so as to handle 1 m2 error.This paper is structured as follows: first, autonomous exploration approaches are detailed in Section 2; next we present our behaviors and FSA design in Section 3; Section 4 follows with the implemented experiments and results; and finally, we present in Section 5 a summary of contributions and conclusions, as well as our future directions.2.?Related WorkMany approaches have been proposed for exploring unknown environments with single and multiple robots.
A deep comparison on several autonomous exploration approaches has been reported in [22] including their main pros and cons. In most of these, the essence is to allow the robots to autonomously navigate to the best unexplored area. Area representation makes the main difference among different techniques. Nevertheless, a popular basis is the frontier-based exploration algorithm introduced by Yamauchi in [4].Main advantages of frontier exploration reside in that there is no world structure required, and that it is useful in cluttered environments and acceptable in large open spaces [23]. On the other hand, the necessity for robust localization and mapping impacts directly on algorithm complexity and the need for world representation.
Basically, the exploration cycle requires to: gather sensor data, share/merge evidence grids (maps), extract edges and match locations, allocate Cilengitide frontiers, and reliably navigate towards the allocated frontier.Concerning frontiers’ allocation, significant works have been proposed using market-based techniques. In [5] a successful multi-robot exploration is achieved with a bidding process. Enzalutamide clinical Nevertheless, the need for a central bid-evaluator agent is an undesired compromise.

omes The eukaryotic

omes. The eukaryotic Romidepsin supplier supergroup Amoebozoa is represented by only one species, Dictyostelium discoideum, while there are no representatives of Rhizaria sequenced. Despite the limitations of the available sequences, we have identified unique types of PARPs in Naegleria gru beri, Trichomonas vaginalis and green algae and clarified the phylogenetic distribution of tankyrases. There are likely to be additional variations of PARPs discovered as more eukaryotic genomes are sequenced and a further advancement of our understanding of evolution of this important proteins superfamily. Clade 5 and vaults The Clade 5 PARPs have a limited phylogenetic distri bution, found only in a subset of animals and amoeba. vPARP was originally identified in a two hybrid screen using the major vault protein pro tein as bait and shown to act as a bona fide PARP.

vPARP associates not only with the ribonucleoprotein vault complex, but also can be found in the nucleus, associated with the telomere and the mitotic spindle. The function of vPARP at any of its locations is unclear. Vaults have been best studied in mammals and in these organisms are composed of three proteins, MVP, TEL1, and vPARP. In addition, sev eral vault specific RNAs are found. The func tion or functions of vaults are still unclear, they are associated with drug resistance and several signalling pathways, as well as the nuclear pore complex. vPARP deficient mice are normal and fertile with no defects in telomeres or vaults. More recently these mice have been found to develop more tumours in response to carcinogens, suggesting a role in chemically induced cancers.

Vaults have been identified in diverse animals and in other eukaryotes such as the amoeba Dictyostelium dis coideum, flatworms, and trypanosomatides. However, vaults appear to be missing from fungi, a number of model animals and in plants. The fact that vPARP does not appear essential for normal development or vault structure in mouse suggests that this protein is not essential for vault func tion. This may explain why organisms that have been demonstrated to contain vaults in their cells do not always encode proteins that look like vPARP. Clade 2 plant specific PARPs are involved in stress responses In addition to containing three Clade 1 PARPs through out and Clade 6 PARPs only in the bryophytes, the land plants contain a unique clade of PARP like proteins.

This clade can be subdivided into two subclades, one of which contains proteins with an N terminal WWE domain. Clade 2 is distinct from Clade 3, which also contains proteins with WWE domains. Batimastat A group within Clade 2, confined to the eudicots within the angios perms, consists of truncated proteins lacking the N terminal WWE domain. Examination of the phylogeny of Clade 2 clearly illustrates the importance of genome duplication during plant evolution, plant spe cies tend to encode gene pairs. The plant Clade 2 proteins have only been investi gated in the model angiosperm Arabidopsis thaliana. Arab

nsistent with action at the level of the LET 23 receptor This su

nsistent with action at the level of the LET 23 receptor. This suggests that SEM 5 might regulate attenuation of LET 23 signalling through ubi quitination and subsequent endocytosis using two differ ent ubiquitin ligases, SLI 1 and CUL 4 DDB 1 CDT 2. Unfortunately, we have been order inhibitor as yet unable to directly assess LET 23 receptor localisation or endocyto sis during vulva development, immunostaining experi ments are inconsistent and current let 23,gfp transgenics are not fully functional. Tests of these mod els will require better reagents to investigate regulation of the LET 23 receptor. Ubiquitination and regulation of Notch signalling Receptor mediated endocytosis is important to termi nate or attenuate signalling, not only for EGFR but also for other signalling pathways, e. g. Notch.

During vulva development, LIN 12 signalling is required for establishment of the secondary cell fate and for the production of the anchor cell, which pro duces LIN 3. Interestingly, SEL 10, an F box and a WD40 containing protein that belongs to the CDC4 CUL 1 family of ubiquitin ligase, has been shown to play an important role in attenuation of LIN 12 signalling. SEL 10 was also shown to physically interact with LIN 12, implying that it regulates signal ling via ubiquitination of LIN 12. Herein we have not investigated the relationship between the CUL 4 DDB 1 CDT 2 ubiquitin ligase complex and LIN 12 signal ling. We did not observe any defects in anchor cell development, a process dependent on LIN 12, however, it has been previously shown for SEL 10 that a sensitised background is required to reveal its activity as an attenuator of LIN 12 signalling.

Therefore, we may not have detected a potential role for CDT 2 in attenuation of LIN 12 signalling. There is also an intimate link between LIN 12 and LET 23 signalling during vulva development. Indeed, high level of LET 23 signalling triggers expression of LIN 12 ligands in the primary P6. p cell. This activates LIN 12 signalling in the flanking secondary cells and ensures down regulation of LET 23 signalling in P5. p and P7. p cells. It is not impossible that the depletion of CDT 2 or CUL 4 impairs LIN 12 signalling and thereby prevents appropriate down regulation of LET 23 signalling in secondary cells, which would cause persistent expres sion of egl 17,cfp in secondary cells.

Localisation of CDT 2 The localisation of CDT 2 fused to GFP is predomi nantly nuclear in interphase and cytoplasmic during mitosis, which seems contrary with a function in endo cytosis. However, we Dacomitinib cannot exclude that a proportion of CDT 2,GFP below our limit of detection is cytoplas mic during interphase. Interestingly, early studies showed that human CDT 2 selleckbio can be detected in the cyto plasm, which would be consistent with a role in ubi quitination of cytoplasmic targets. Alternatively, the CUL 4 DDB 1 CDT 2 E3 ubiquitin ligase complex may be active in the cytoplasm only after nuclear breakdown. Further experiments will be required to establish w
