Nuclear export of signal recognition particle DNA is a facilitated process that involves the Alu sequence domain

description: The signal recognition particle is a cytoplasmic RNA-protein complex that mediates translocation of secretory polypeptides into the endoplasmic reticulum. We have used a Xenopus oocyte microinjection assay to determine how signal recognition particle (SRP) RNA is exported from the nucleus. Following nuclear injection, SRP RNA accumulated in the cytoplasm while cytoplasmically injected SRP RNA did not enter the nucleus. Cytoplasmic accumulation of SRP RNA was an apparently facilitated process dependent on limiting trans-acting factors, since nuclear export exhibited saturation kinetics and was completely blocked either at low temperature or by wheat germ agglutinin, a known inhibitor of nuclear pore-mediated transport. At least one target for trans-acting factors that promote nuclear export of SRP RNA appears to be the Alu element of the molecule, since a transcript consisting of only the Alu sequence was exported from the nucleus in a temperature-dependent manner and the Alu transcript competed in the nucleus for transport with intact SRP RNA. Although the identities of trans-acting factors responsible for SRP RNA transport are at present unknown, we suggest that proteins contained within the cytoplasmic form of SRP are candidates. Consistent with this idea were the effects of a mutation in SRP RNA that prevented binding of two known SRP proteins to the Alu sequence.

description: Tyrosine phosphorylation is known to regulate the formation of focal adhesions in cells adhering to extracellular matrix (ECM). We have investigated the possible involvement of tyrosine phosphorylation and the focal adhesion kinase (FAK) in the cytoskeletal changes induced by serum or lysophosphatidic acid (LPA) in quiescent Swiss 3T3 fibroblasts. As shown previously by others, quiescent cells stimulated with serum or LPA reveal a rapid reappearance of focal adhesions and stress fibers. Here we show that this is accompanied by an increase in phosphotyrosine in focal adhesions and specifically an increase in the tyrosine phosphorylation of FAK. The LPA-stimulated reappearance of focal adhesions and stress fibers is blocked by inhibitors of phospholipase C but not by pertussis toxin (PTX), indicating that this LPA signaling pathway is mediated by phospholipase C activation and does not involve PTX-sensitive G proteins. In the absence of serum or LPA, these cytoskeletal effects and the tyrosine phosphorylation of FAK can be mimicked by sodium orthovanadate in conjunction with hydrogen peroxide, agents that inhibit protein tyrosine phosphatases and thereby elevate levels of phosphotyrosine. Two tyrosine kinase inhibitors, erbstatin and genistein block both the serum-induced tyrosine phosphorylation of FAK and the assembly of focal adhesions and stress fibers. Two other tyrosine kinase inhibitors, tyrphostins 47 and 25, previously shown to inhibit FAK, failed to prevent FAK phosphorylation or the reassembly of focal adhesions and stress fibers in response to serum. However, these inhibitors did prevent FAK phosphorylation and cytoskeletal assembly in response to lysophosphatidic acid (LPA), one component of serum previously shown to stimulate assembly of focal adhesions and stress fibers. Our findings suggest that the response to serum is complex and that although FAK phosphorylation is important, other tyrosine kinases may also be involved.

description: Methods developed at the Texas Advanced Computing Center (TACC) are described and demonstrated for automating the construction of an elastic, virtual cluster emulating the Stampede2 high performance computing (HPC) system. The cluster can be built and/or scaled in a matter of minutes on the Jetstream self-service cloud system and shares many properties of the original Stampede2, including: i) common identity management, ii) access to the same file systems, iii) equivalent software application stack and module system, iv) similar job scheduling interface via Slurm. We measure time-to-solution for a number of common scientific applications on our virtual cluster against equivalent runs on Stampede2 and develop an application profile where performance is similar or otherwise acceptable. For such applications, the virtual cluster provides an effective form of "cloud bursting" with the potential to significantly improve overall turnaround time, particularly when Stampede2 is experiencing long queue wait times. In addition, the virtual cluster can be used for test and debug without directly impacting Stampede2. We conclude with a discussion of how science gateways can leverage the TACC Jobs API web service to incorporate this cloud bursting technique transparently to the end user.

description: In this study, we examined the ASCAT backscatter data from Metop-A from 2007 to 2016 to characterize spatial and temporal variability in the vegetation parameters of the TU Wien Soil Moisture Retrieval approach (TUW SMR) across the North American Grasslands. The vegetation parameters are the slope and curvature of a second order Taylor polynomial used to describe the incidence angle dependence of backscatter σ°. A recent development allows the vegetation parameters to be determined dynamically using the local slope values within a prescribed temporal window. Seasonal, interannual and diurnal variations in the vegetation parameters were found to vary across grassland cover types, reflecting variations in soil moisture availability and growing season length. While the slope has always been considered a measure of vegetation density, our results show that curvature also contains information about vegetation. Drought events in 2011 and 2012 resulted in extensive negative σ 40∘ and soil moisture anomalies during the maximum biomass period. Contiguous anomalies in slope and curvature were observed where the severity and persistence of the drought were enough to impact vegetation. Observed diurnal differences in slope and curvature suggest that daily moisture transport within the vegetation influences the relative dominance of scattering from the vegetation and soil surface.

description: Indirect precision data are used to constrain the masses of possible extra Z^prime bosons and their mixings with the ordinary Z. We study a variety of Z^prime bosons as they appear in E_6 and left-right unification models, the sequential Z boson, and the example of an additional U(1) in a concrete model from heterotic string theory. In all cases the mixings are severely constrained (sin theta < 0.01). The lower mass limits are generally of the order of several hundred GeV and competitive with collider bounds. The exception is the Z_psi boson, whose vector couplings vanish and whose limits are weaker. The results change little when the rho parameter is allowed, which corresponds to a completely arbitrary Higgs sector. On the other hand, in specific models with minimal Higgs structures the limits are generally pushed into the TeV region.

description: The field of heavy ion physics is at a crossroads in understanding experimental signatures of collectivity in small collision systems, p + p and p(d/3He) + A, at RHIC and the LHC. A wealth of data obtained in the latter class of asymmetric systems indicate the existence of particle emission patterns similar to those observed in larger A+A collisions [1], raising the question of whether the same physics is at play in both cases, lest the cruelty of nature be somehow exposed. In this talk, we present an extension of earlier studies using the quasiparticle transport model AMPT to predict particle emission patterns in the smallest of collision systems, namely p + p and e+e-. The e+e- results have been previously published [2] and we thus focus here on an extended set of calculations, as shown at the Quark Matter 2018 Conference.

Influence of next-nearest-neighbor electron hopping on the static and dynamical properties of the 2D Hubbard model

description: Comparing experimental data for high temperature cuprate superconductors with numerical results for electronic models, it is becoming apparent that a hopping along the plaquette diagonals has to be included to obtain a quantitative agreement. According to recent estimations the value of the diagonal hopping $t'$ appears to be material dependent. However, the values for $t'$ discussed in the literature were obtained comparing theoretical results in the weak coupling limit with experimental photoemission data and band structure calculations. The goal of this paper is to study how $t'$ gets renormalized as the interaction between electrons, $U$, increases. For this purpose, the effect of adding a bare diagonal hopping $t'$ to the fully interacting two dimensional Hubbard model Hamiltonian is investigated using numerical techniques. Positive and negative values of $t'$ are analyzed. Spin-spin correlations, $n(\bf{k})$, $\langle n\rangle$ vs $μ$, and local magnetic moments are studied for values of $U/t$ ranging from 0 to 6, and as a function of the electronic density. The influence of the diagonal hopping in the spectral function $A(\bf{k},ω)$ is also discussed, and the changes in the gap present in the density of states at half-filling are studied. We introduce a new criterion to determine probable locations of Fermi surfaces at zero temperature from $n(\bf{k})$ data obtained at finite temperature. It appears that hole pockets at ${\bf{k}}=(π/2,π/2)$ may be induced for negative $t'$ while a positive $t'$ produces similar features at ${\bf{k}}=(π,0)$ and $(0,π)$. Comparisons with the standard 2D Hubbard ($t'=0$) model indicate that a negative $t'$ hopping amplitude appears to be dynamically generated. In general, we conclude that it is very dangerous to extract a bare parameter of the Hamiltonian $(t')$ from PES data where

Oscillating mitotic newt lung cell kinetochores are, on average, under tension and rarely push
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: Experimentally introduced tension on kinetochores and their centromeres has been shown to stabilize kinetochore attachment to microtubules, modify kinetochore directional instability, and regulate cell-cycle progression into anaphase. In mitosis, kinetochore tension and the stretch of centromere chromatin are produced by the movement of sister kinetochores toward opposite poles and astral ejection forces on the chromosome arms. However, newt lung cell kinetochores oscillate between poleward and away from the pole motility states throughout mitosis, indicating kinetochores are not under constant tension. To test whether kinetochores are under net tension while they are oscillating, and how often they are under compression and pushing into the chromosome, we measured the distance between sister kinetochores in newt lung cells using both video-enhanced differential interference contrast microscopy (VE-DIC) and immunofluorescence microscopy. We found that for chromosomes in which sister kinetochores are attached to opposite spindle poles, centromeres are, on average, stretched (2.2 microns in living cells and 1.8 microns in fixed cells) with respect to the inter-kinetochore 'rest' length (1.1 microns in living and fixed cells). For chromosomes in which only one kinetochore is attached to the spindle, the centromere chromatin associated with the tethered kinetochore is, on average, stretched to approximately half of the average inter-kinetochore distance measured for chromosomes in which both kinetochores are attached. We conclude that while newt lung cell kinetochores oscillate between states of P and AP movement, they are under tension approximately 90% of the time and under compression less than 6% of the time.

description: Indoor localisation methods are an essential part for the management of COVID-19 restrictions, social distancing, and the flow of people in the indoor environment. Moving towards an open work space in this scenario requires effective real-time localisation services and tools, along with a comprehensive understanding of the 3D indoor space. This project’s main objective is to analyse how ArcGIS Indoors can be used with location awareness methods to elaborate and develop space management tools for COVID- 19 restrictions in order to reopen the workspace for TU Delft Campus. This was accomplished by using six Arduino micro controllers, which were programmed in C++ to scan all available Wi-Fi fingerprints in the east wing of the Faculty of Architecture and the Built Environment of TU Delft and send over the data to an ArcGIS Indoor Information Model (AIIM). The data stored on the AIIM is then accessed using the app on the user’s Android device using REST Application Programming Interface (API) where a kNN based matching algorithm then identifies the location of the user. The results show that the localisation is not consistent for rooms that are directly above each other or share common access points. However, when functioning to locate different tables inside a room, the system proved to uniquely distinguish between the specific tables. As a result, we can conclude that based on the size of the rooms, more Arduino devices should be installed to achieve an ideal accuracy. Finally, recommendations are made for the continuation of this research.

description: We study the phenomenology of a new Minimally-extended Supersymmetric Standard Model (nMSSM) where a gauge singlet superfield is added to the MSSM spectrum. The superpotential of this model contains no dimensionful parameters, thus solving the mu-problem of the MSSM. A global discrete R-symmetry, forbidding the cubic singlet self-interaction, imposed on the complete theory, guarantees its stability with respect to generated higher-order tadpoles of the singlet and solves both the domain wall and Peccei-Quinn axion problems. We give the free parameters of the model and display some general constraints on them. A particular attention is devoted to the neutralino sector where a (quasi-pure) singlino appears to be always the LSP of the model, leading to additional cascades, involving the NLSP -> LSP transition, compared with the MSSM. We then present the upper bounds on the masses of the lightest and next-to-lightest -- when the lightest is an invisible singlet -- CP-even Higgs bosons, including the full one-loop and dominant two-loop corrections. These bounds are found to be much higher than the equivalent ones in the MSSM. Finally, we discuss some phenomenological implications for the Higgs sector of the nMSSM in Higgs production at future hadron colliders.

Polar localization of a dihydropyridine receptor on living Fucus zygotes

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: We have used a fluorescently-labeled dihydropyridine (FL-DHP) to vitally stain living Fucus zygotes during the establishment of cell polarity. Localization of FL-DHP is primarily at the plasma membrane and FL-DHP binding is competitively blocked by an unlabeled dihydropyridine. Distribution of FL-DHP is initially symmetrical before fixation of the polar axis, but becomes asymmetrical in response to a unilateral light gradient. The distribution of FL-DHP receptors can be relocalized when the direction of the photopolarizing stimulus is changed. Treatment of cells with cytochalasin B prior to axis fixation reversibly prevents localization of FL-DHP receptors. Observation of FL-DHP labeling by time-lapse fluorescence microscopy indicates that the existing receptors are redistributed during polar axis formation. The asymmetric distribution of FL-DHP receptors coincides temporally and spatially with increased local intracellular calcium ion concentrations, as measured by calcium green dextran. Based on the site, timing, photo-reversibility, and actin dependence of the asymmetric localization of FL-DHP receptors, we conclude that FL-DHP is a vital probe for the later stage of polar axis formation in Fucus zygotes. Furthermore, we propose that FL-DHP receptors correspond to ion channels that are transported to the future site of polar growth to create the changes in local calcium concentration required for polarity establishment.

description: In this Brief Report, a non-standard solution to the solar neutrino problem is revisited. This solution assumes that neutrino flavors could have different couplings to gravity, hence, the equivalence principle is violated in this mechanism. The gravity induced mixing has the potential of accounting for the current solar neutrino data from several experiments even for massless neutrinos. We fit this solution to the total rate of neutrino events in the SuperKamiokande detector together with the total rate from other detectors and also with the most recent results of the SuperKamiokande results for the recoil-electron spectrum.

Localization of integral membrane peptidylglycine alpha-amidating monooxygenase in neuroendocrine cells
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: Peptidylglycine alpha-amidating monooxygenase (PAM) catalyzes the amidation of glycine-extended peptides in neuroendocrine cells. At steady state, membrane PAM is accumulated in a perinuclear compartment. We examined the distribution of membrane PAM in stably transfected AtT-20 cells and compared its localization to markers for the trans-Golgi network (TGN), endosomes, and lysosomes. At the light microscopic level, the distribution of membrane PAM does not overlap extensively with lysosomal markers but does overlap with TGN38 and with SCAMP, a component of post-Golgi membranes involved in recycling pathways. By immunoelectron microscopy, membrane PAM is present in tubulovesicular structures which constitute the TGN; some of these PAM-containing tubulovesicular structures are more distal to the Golgi stacks and do not contain TGN38. While some POMC-derived peptides are present in tubulovesicular structures like those that contain membrane PAM, the majority of the POMC-derived peptides are present in secretory granules. There is little overlap between the steady state distribution of membrane PAM and internalized FITC-transferrin in the early endosomes. Few of the perinuclear PAM-containing structures are labeled with HRP or WGA-HRP even following long incubations. Therefore, membrane PAM is localized to perinuclear tubulovesicular structures which are partially devoid of TGN38 and are not all endosomal in origin.

The alternatively spliced domains EIIIB and EIIIA of human fibronectin affect cell adhesion and spreading

description: Fibronectin has a complex pattern of alternative splicing at the pre-mRNA level leading to the expression of different isoforms. The alternatively spliced domains EIIIB and EIIIA are known to be prominently expressed during development and wound healing. While the other spliced domain (CS-segment) is known to promote cell adhesion in a cell type specific manner, the biological functions of the spliced domains EIIIB and EIIIA are not well understood. In the present study, we have prepared expression proteins of specific domains of human fibronectin using a prokaryotic expression system and used the purified fragments to test their ability to support adhesion and spreading of cultured cells. Fragments from type-III domains #7 to #12 were prepared in various combinations to include or exclude the spliced domains EIIIB and EIIIA. The results indicate that cultured NIL fibroblasts adhere to many of the fragments tested. However, the cell adhesion and spreading are enhanced, especially at lower concentrations, to fragments including the domain EIIIB. The inclusion of domain EIIIA led to a decrease in the adhesion of cells and those that adhered did not spread well. When tested in a centrifugal cell adhesion assay, fragments including domain EIIIB resisted the detaching forces and stayed adhered. Fragments that included domain EIIIA were unable to resist the detaching centrifugal forces to the same extent as the fragments that included domain EIIIB alone. These results suggest that the spliced domain EIIIB may be serving important biological functions in enhancing cell adhesion and spreading. This is likely to be mediated by conformational effects because domain EIIIB alone neither exhibited any adhesive activity nor competed in inhibiting adhesion to fragments #7-10.
Collapse of Spin-Splitting in the Quantum Hall Effect

description: It is known experimentally that at not very large filling factors $ν$ the quantum Hall conductivity peaks corresponding to the same Landau level number $N$ and two different spin orientations are well separated. These peaks occur at half-integer filling factors $ν= 2 N + 1/2$ and $ν= 2 N + 3/2$ so that the distance between them $δν$ is unity. As $ν$ increases $δν$ shrinks. Near certain $N = N_c$ two peaks abruptly merge into a single peak at $ν= 2N + 1$. We argue that this collapse of the spin-splitting at low magnetic fields is attributed to the disorder-induced destruction of the exchange enhancement of the electron $g$-factor. We use the mean-field approach to show that in the limit of zero Zeeman energy $δν$ experiences a second-order phase transition as a function of the magnetic field. We give explicit expressions for $N_c$ in terms of a sample's parameters. For example, we predict that for high-mobility heterostructures $N_c = 0.9 d n^{5/6} n_i^{-1/3},$ where $d$ is the spacer width, $n$ is the density of the two-dimensional electron gas, and $n_i$ is the two-dimensional density of randomly situated remote donors.

description: We propose a compact MEMS-based optical autocorrelator based on a micromachined Michelson interferometer in silicon and the two-photon absorption non-linearity in a photodetector. The miniaturized autocorrelator has a scanning range of 1.2 ps and operates in the wavelength range of 1100-2000 nm. The device measures the interferometric autocorrelation due to its collinear nature, from which the intensity autocorrelation can be calculated. The field autocorrelation can also be measured, from which the optical pulse spectrum can be calculated. A theoretical model based on Gaussian beam propagation is developed to study the effect of optical beam divergence, pulse dispersion, tilt angle between the interferometer mirrors, and amplitude mismatch between the interfering pulses. This model explains many of the effects observed in experimental measurements due to the use of a MEMS interferometer. The experimental results of autocorrelation signals for several pulses in the order of 100 fs are compared to a commercial autocorrelator and a good match is found.

When a high sediment load causes the density excess, such currents are called turbidity currents. They can supply momentum, heat, oxygen, sediments, nutrients and contaminants to deep lake basins and are the main cause of reservoir storage capacity loss. Even with steady inflow, turbidity currents have been observed to exhibit regularly pulsing velocity patterns, which are likely to enhance mixing between the inflowing and the ambient waters. Previously, literature linked this pulsing to several mechanisms, including interfacial waves such as Kelvin-Helmholtz instabilities and Rayleigh-Taylor instabilities related to surface lobes along the plunge line. However, to our knowledge, field measurements of the latter have not been reported. In the present study, field measurements of the plunging inflow of the negatively buoyant Rhône River into Lake Geneva (Switzerland/France) were carried out. Vessel-mounted ADCP measurements of the longitudinal flow field of the plunging flow and the subsequent turbidity current were combined with remote time-lapse imagery capturing related surface patterns. The ADCP measurements confirm that the inflowing river water plunges and forms a turbidity current. At the turbidity current-ambient water interface, regularly spaced “bulges” in the velocity pattern suggest pulsing. Simultaneously taken remote time-lapse images show that at the surface, the inflowing sediment-rich water forms a distinct plume with a triangular shape leading away from the river mouth in the downstream direction towards a sharp tip. At the edge and in the immediate surroundings of this plume, a variety of intermittent lobes and vortical structures whose periodicity might be related to that of the velocity pulsing in the turbidity current, is observed.

description: This work concerns \emph{ab initio} calculations of the complete potential energy curve and spectroscopic constants for the ground state $X^1Σ_g^+$ of the beryllium dimer, Be$_2$. High accuracy and reliability of the results is one of the primary goals of the paper. To this end we apply large basis sets of Slater-type orbitals combined with high-level electronic structure methods including triple and quadruple excitations. The effects of the relativity are also fully accounted for in the theoretical description. For the first time the leading-order quantum electrodynamics effects are fully incorporated for a many-electron molecule. Influence of the finite nuclear mass corrections (post-Born-Oppenheimer effects) turns out to be completely negligible for this system. The predicted well-depth ($D_e=934.5\pm2.5\,\mbox{cm}^{-1}$) and the dissociation energy ($D_0=808.0\,\mbox{cm}^{-1}$) are in a very good agreement with the most recent experimental data. We confirm the existence of the weakly bound twelfth vibrational level [Patkowski et al., Science 326, 1382 (2009)] and predict that it lies just about 0.5 $\mbox{cm}^{-1}$ below the onset of the continuum.

The composition and dynamics of cell-substratum adhesions in locomoting fish keratocytes

description: Close contacts are the predominant type of cell-substratum adhesion in rapidly moving cells yet little is known about their composition and dynamics. To address these issues we have attempted to identify the molecular components of close contacts formed in rapidly moving fish epithelial keratocytes. In addition we have utilized the simple shape of keratocytes to explore the relationship between close contact formation and rapid locomotion. Beta1 integrin and talin molecules were found to be localized within a narrow rim of very close contact along the leading edge. These molecules together with vinculin were also found within small foci distributed evenly throughout the lamella, corresponding to regions of variable close contact. Alpha-actinin was found in foci within older, more posteriorly located regions of the lamella and along stress fibers. In addition to close contacts, small focal adhesion-like structures which stained positively for all antibodies tested were found at the tips of stress fibers within retracting cell margins. Interference reflection and total internal reflection microscopy of moving keratocytes showed cell-substratum contacts to be organized into distinct patterns that appear to move forwards, in concert with the leading edge. A feature common to all cells is a rim of very close contact at the leading edge. This region is specialized for the formation of new cell-substratum adhesions and is the site where patterns of close contact are generated. We have found that cell locomotion is most rapid when a uniform contact pattern is present but cell speed is progressively reduced as the contact pattern becomes more irregular. Furthermore, the local rate of lamellar extension is most rapid when underlain by regions of intermediate closeness to the substratum, but is reduced or ceases if the underlying contact is either very close or more distant, respectively. Our results suggest that close contacts and focal adhesions are related structures formed from a common hierarchy of molecular interactions. In addition the relationship between close contact formation and lamellar extension indicates a direct coupling between these two processes at the leading edge. Furthermore, we can explain the dynamic behaviour of close contacts in terms of the relative rates of trapping and release of component molecules that is initiated at the leading edge. We suggest that regulation of the molecular dynamics involved in leading edge specialization determines both the pattern of cell-substratum contacts and the net rate of actin filament assembly.

description: Quantum resources can improve communication complexity problems (CCPs) beyond their classical constraints. One quantum approach is to share entanglement and create correlations violating a Bell inequality, which can then assist classical communication. A second approach is to resort solely to the preparation, transmission and measurement of a single quantum system; in other words quantum communication. Here, we show the advantages of the latter over the former in high-dimensional Hilbert space. We focus on a family of CCPs, based on facet Bell inequalities, study the advantage of high-dimensional quantum communication, and realise such quantum communication strategies using up to ten-dimensional systems. The experiment demonstrates, for growing dimension, an increasing advantage over quantum strategies based on Bell inequality violation. For sufficiently high dimensions, quantum communication also surpasses the limitations of the post-quantum Bell correlations obeying only locality in the macroscopic limit. Surprisingly, we find that the advantages are tied to the use of measurements that are not rank-one projective. We provide an experimental semi-device-independent falsification of such measurements in Hilbert space dimension six.

Numerical Study of the Fundamental Modular Region in the Minimal Landau Gauge

description: We study numerically the so-called fundamental modular region Lambda, a region free of Gribov copies, in the minimal Landau gauge for pure SU(2) lattice gauge theory. To this end we evaluate the influence of Gribov copies on several quantities --- such as the smallest eigenvalue of the Faddeev-Popov matrix, the third and the fourth derivatives of the minimizing function, and the so-called horizon function --- which are used to characterize the region Lambda. Simulations are done at four different values of the coupling: beta = 0, 0.8, 1.6, 2.7, and for volumes up to 16^4. We find that typical (thermalized and gauge-fixed) configurations, including those belonging to the region Lambda, lie very close to the Gribov horizon $\partial Ω$, and are characterized, in the limit of large lattice volume, by a negative-definite horizon tensor.
