description: A growing number of RNA sequences are now known to have distributions of multiple stable sequences. Recent algorithms use the list of nucleotides in a sequence and auxiliary experimental data to predict such distributions. Although the algorithms are largely successful in identifying a distribution's constituent structures, it remains challenging to recover their relative weightings. In this paper, we quantify this issue using a total variation distance. Then, we prove under a Nussinov-Jacobson model that a large proportion of RNA structure pairs cannot be jointly reconstructed with low total variation distance. Finally, we characterize the uncertainty in predicting conformational ratios by analyzing the amount of information in the auxiliary data.

description: Abstract: "The Fokker-Planck equation, or forward Kolmogorov equation, describes the evolution of the probability density for a stochastic process associated with an Ito stochastic differential equation. It pertains to a wide variety of time-dependent systems in which randomness plays a role. In this paper, we are concerned with Fokker-Planck equations for which the drift term is given by the gradient of a potential. For a broad class of potentials, we construct a time-discrete, iterative variational scheme whose solutions converge to the solution of the Fokker-Planck equation. The major novelty of this iterative scheme is that the time step is governed by the Wasserstein metric on probability measures. This formulation enables us to reveal an appealing, and previously unexplored, relationship between the Fokker-Planck equation and the associated free energy functional. Namely, we demonstrate that the dynamics may be regarded as a gradient flux, or a steepest descent, for the free energy with respect to the Wasserstein metric."

description: We show that U(N) Yang-Mills theory on noncommutative Minkowski space-time can be renormalized, in a BRS invariant way, at the one-loop level, by multiplicative dimensional renormalization of its coupling constant, its gauge parameter and its fields. It is shown that the Slavnov-Taylor equation, the gauge-fixing equation and the ghost equation hold, up to order $\hbar$, for the MS renormalized noncommutative U(N) Yang-Mills theory. We give the value of the pole part of every 1PI diagram which is UV divergent.

Abstract of associated publication:
A fundamental task of the visual system is to respond to both increases and decreases of luminance with action potentials (ON and OFF responses). OFF responses are stronger, faster, and more salient than ON responses in primary visual cortex (V1) of both cats and primates, but in ferrets and mice ON responses can be stronger, weaker, or balanced in comparison to OFF responses. These discrepancies could arise from differences in species, experimental techniques, or stimulus properties, particularly retinotopic location in the visual field, as has been speculated; however, the role of retinotopy for ON/OFF dominance has not been systematically tested across multiple scales of neural activity within species. Here, we measured OFF versus ON responses across large portions of visual space with silicon probe and whole-cell patch-clamp recordings in mouse V1 and lateral geniculate nucleus (LGN). We found that OFF responses dominated in the central visual field, whereas ON and OFF responses were more balanced in the periphery. These findings were consistent across local field potential (LFP), spikes, and subthreshold membrane potential in V1, and were aligned with spatial biases in ON and OFF responses in LGN. Our findings reveal that retinotopy may provide a common organizing principle for spatial modulation of OFF versus ON processing in mammalian visual systems.

description: Robust solving of critical large power flow cases (with 50k or greater buses) forms the backbone of planning and operation of any large connected power grid. At present, reliable convergence with applications of existing power flow tools to large power systems is contingent upon a good initial guess for the system state. To enable robust convergence for large scale systems starting with an arbitrary initial guess, we extend our equivalent circuit formulation for power flow analysis to include a novel continuation method based on transmission line (Tx) stepping. While various continuation methods have been proposed for use with the traditional PQV power flow formulation, these methods have either failed to completely solve the problem or have resulted in convergence to a low voltage solution. The proposed Tx Stepping method in this paper demonstrates robust convergence to the high voltage solution from an arbitrary initial guess. Example systems, including 75k+ bus test cases representing different loading and operating conditions for Eastern Interconnection of the U.S. power grid, are solved from arbitrary initial guesses.Interconnection of the U.S. power grid, are solved from arbitrary initial guesses.

description: Nasopharyngeal carcinoma (NPC) is a highly metastatic cancer that is endemic in South East Asia and Southern China. Despite the gravity of the disease, the current knowledge on its molecular pathogenesis is still inadequate to improve the disease management. The present study seeks to understand the molecular mechanism of NPC, with an aim to identify potential therapeutic targets or biomarkers. From a previous expression microarray study, Four – Jointed Box 1 (FJX1) gene was found to be upregulated in NPC compared to non-cancerous controls with negligible expression in 5 vital normal human organs. Human FJX1 is a Drosophila orthologue of four-jointed (fj) gene which codes for a Golgi-resident kinase that phosphorylates specific cadherin domains and functions downstream of the Notch and Hippo signaling pathways. The overexpression of FJX1 in primary NPC tissues was confirmed at both mRNA and protein levels, while its low expression was validated in 16 normal human organs. Both overexpression and knockdown experiments showed that FJX1 increased the aggressiveness of NPC cells by promoting cell proliferation, invasion and anchorage-independent growth. Concomitant change of Cyclins D1 and E1 levels were observed with FJX1 level, suggesting FJX1 enhances cell proliferation through cell cycle regulation. The results of the present study demonstrate for the first time the overexpression of FJX1 in NPC as a putative oncogene, and it represents an attractive therapeutic target for NPC.

description: A proper 2-tone k-coloring of a graph is a labeling of the vertices with elements from ([k]2) such that adjacent vertices receive disjoint labels and vertices distance 2 apart receive distinct labels. The 2-tone chromatic number of a graph G, denoted τ 2(G) is the smallest k such thatG admits a proper 2-tone k coloring. In this paper, we prove that w.h.p. for p≥Cn−1/4ln9/4n,τ2(Gn,p)=(2+o(1))χ(Gn,p) where χ represents the ordinary chromatic number. For sparse random graphs with p = c/n, c constant, we prove that τ2(Gn,p)=⌈(8Δ+1−−−−−−√+5)/2 where Δ represents the maximum degree. For the more general concept of t-tone coloring, we achieve similar results.
Non-identical particle femtoscopy in models with single freeze-out

description: We present femtoscopic results from hydrodynamics-inspired thermal models with single freeze-out. Non-identical particle femtoscopy is studied and compared to results of identical particle correlations. Special emphasis is put on shifts between average space-time emission points of non-identical particles of different masses. They are found to be sensitive to both the spatial shift coming from radial flow, as well as average emission time difference coming from the resonance decays. The Therminator Monte-Carlo program was chosen for this study because it realistically models both of these effects. In order to analyze the results we present and test the methodology of non-identical particle correlations.

description: Excerpts from the report: Representatives of the Eastern Shore of Virginia sweetpotato industry requested in January 1960 that an objective appraisal be made of their marketing program. They are becoming increasingly concerned about the impact upon their competitive position of changes in production, consumption, utilization, and distribution. Coupled with these have been changes in procurement practices and product requirements which are affecting established marketing procedures. In compliance with this request, Farmer Cooperative Service and the Virginia Department of Agriculture and Immigration jointly undertook a study. The study first points out some significant changes which have occurred— and are taking place—in the sweetpotato economy, evaluates their implication to growers and shippers on the Shore, and then presents an analysis of their marketing program along with suggested courses of action which may help them to capitalize on these changes.

description: We compute the electric conductivity of quark matter at finite temperature $T$ and quark chemical potential $μ$ under a magnetic field $B$ beyond the Lowest Landau level approximation. The electric conductivity transverse to $B$ is dominated by the Hall conductivity $σ_H$. For the longitudinal conductivity $σ_\parallel$, we need to solve kinetic equations. Then, we numerically find that $σ_\parallel$ has only mild dependence on $μ$ and the quark mass $m_q$. Moreover, $σ_\parallel$ first decreases and then linearly increases as a function of $B$, leading to an intermediate $B$ region which looks consistent with the experimental signature for the chiral magnetic effect. We also point out that $σ_\parallel$ at nonzero $B$ remains within the range of the lattice-QCD estimate at $B=0$.

In this paper, we focus on trying to solve the most common challenges related to supervised learning algorithms by using mixture probability distribution functions. With this modeling strategy, we identify sub-labels and generate synthetic data in order to reach better classification accuracy. It means we focus on increasing the training data synthetically to increase the classification accuracy.

description: Lignin is an abundant biopolymer and a promising source of feedstock for high-value chemicals and energy materials, however, application methods of lignin into valuable products is yet to be fully explored. This study explores the valorization of lignin derived from lignin-rich endocarp biomass through the development of lignin-derived electrode materials. The chemical composition and cellular structure of the endocarps were characterized using HPLC and scanning electron microscopy (SEM) imaging. Mechanical properties of walnut and peach endocarps and preprocessing requirements were investigated using nanoindentation and specific energy consumption during grinding. Next, lignin was extracted from endocarps using deep eutectic solvent and alkaline pretreatment methods and applied in the synthesis of carbon-silicon nanocomposites for energy storage application. The lignin derived composite electrodes exhibited impressive electrochemical performance in a half-coin cell lithium-ion battery with the DES and alkaline lignin retaining average discharge capacities of 1552 mAh/g and 1602 mAh/g, respectively, after 200 cycles. Results from this study provide a better understanding of structure and property of endocarp biomass feedstocks and demonstrate the utilization of endocarp derived lignin in electrochemical energy storage applications thereby improving the economic efficiency of biomass conversion.

This approach gives a systematic way to study algebraic and $p$-adic properties of real-analytic Eisenstein series. In the first part of this paper we provide an alternative algebraic construction of Eisenstein--Kronecker series via the Poincaré bundle. Building on this, we give in the second part a new conceptional construction of Katz' two-variable $p$-adic Eisenstein measure through $p$-adic theta functions of the Poincaré bundle.

description: Magnetic excitations in a weakly coupled spin dimers and chains compound Cu2Fe2Ge4O13 are measured by inelastic neutron scattering. Both structure factors and dispersion of low energy excitations up to 10 meV energy transfer are well described by a semiclassical spin wave theory involving interacting Fe$^{3+}$ ($S = 5/2$) chains. Additional dispersionless excitations are observed at higher energies, at $\hbar ω= 24$ meV, and associated with singlet-triplet transitions within Cu$^{2+}$-dimers. Both types of excitations can be understood by treating weak interactions between the Cu$^{2+}$ and Fe$^{3+}$ subsystems at the level of the Mean Field/ Random Phase Approximation. However, this simple model fails to account for the measured temperature dependence of the 24 meV mode.

description: The Handwritten Calculator integrates the practicality of handwritten mathematics with sophisticatedcalculations to combine them into a seamless interface for carrying out calculations. By using computervision, machine learning, and human-computer interaction the system has the ability to recognize andprocess handwritten mathematics and allows for a natural experience. The system is capable of processinghandwritten notation using contour detection and, even more intricately, CNNs (convolutional neuralnetworks). As the system attempts to closely reproduce handwritten equations into a digital format, it alsoprovides output as the calculations are produced; as the system takes into consideration mistakes easily madewhen submitting notation in real-time. This application provides users with a higher degree of accuracy andaccessibility for those who find it easier to work through problems in hand-written notation than with akeyboard or mouse. The low-cost, user-friendly system is meant to be available for students, educators,professionals or anyone interested in using. The Handwritten Calculator is a step in the advancement ofhuman-computer interaction and recreating the traditional way of working hand-in-hand with computingcapability.

description: No abstracts are to be cited without prior reference to the author.The U.S. National Oceanic and Atmospheric Administration’s National Marine Fisheries Service (NOAA Fisheries) instituted the Center for Independent Experts (CIE) in 1998 as a national peer-review program. Operations of the CIE, run under a contract with the University of Miami, maintain the independence of the reviewers, and follow strict conflict of interest guidelines. The review process meets the requirements of the Information Quality Act, which covers regulatory, rather than academic, peer reviews (e.g., reviewer identities are published). The CIE consists of a coordination team, responsible for day-to-day activities, such as identifying reviewers and handling logistics, and a steering committee, which provides oversight and approval. The CIE also provides administrative support. NOAA Fisheries initiates reviews through formal requests to the CIE, coordinates development of the Statement of Work, and has final approval authority for review reports. This approval is based only on compliance with the Statement of Work, and cannot be based on report contents. In recent years the CIE has averaged 16 reviews per year, the majority of which were on fish stock assessments. The recently re-authorized Magnuson-Stevens Act, which governs U.S. marine fisheries, contains a new requirement to set annual catch limits for approximately 530 stocks. This mandate will significantly impact the types and numbers of peer reviews of stock assessments, including reviews conducted by the CIE, as well as reviews that may be conducted by other entities.

description: To investigate the effects of extremely low-frequency electromagnetic fields (ELF-EMFs) stimulation on sodium channel currents (INa), transient outward potassium channel currents (IA) and delayed rectifier potassium channel currents (IK) on hippocampal CA1 pyramidal neurons of young Sprague–Dawley rats. CA1 pyramidal neurons of rat hippocampal slices were subjected to ELF-EMFs stimulation with different frequencies (15 and 50 Hz), intensities (0.5, 1 and 2 mT) and durations (10, 20 and 30 min). The INa, IA and IK of neurons were recorded by a whole-cell patch-clamp method. ELF-EMFs stimulation enhanced INa densities, and depressed IA and IK densities. In detail, INa was more sensitive to the variation of intensities and frequencies of ELF-EMFs, whereas IA and IK were mainly affected by the variation of the duration of ELF-EMFs. ELF-EMFs stimulation altered activation and deactivation properties of INa, IA and IK. ELF-EMFs stimulation plays a role as a regulator rather than an inducer for ion channels. It might change the transition probability of ion channel opening or closing, and might also change the structure and function of the ion channel which need to be proved by the further technical method.
General Relativistic Constraints on Emission Models of Anomalous X-ray Pulsars

description: Most models of anomalous X-ray pulsars (AXPs) account for the observed X-ray spectra and pulsations by means of radiation processes that occur on the surfaces of neutron stars. For any such model, general relativistic deflection of light severely suppresses the amplitude of the observed pulsations. We calculate the expected pulsation amplitudes of AXPs according to various models and compare the results with observations. We show that the high (<= 70%) pulse amplitudes observed in some AXPs can be accounted for only if the surface emission is localized (spot radius <40 degrees) and strongly beamed (cos^n[theta'] with n>2, where theta' is the angle to the normal). These constraints are incompatible with those cooling and magnetar models in which the observed X-rays originate as thermal emission from the neutron-star surface. Accretion models, on the other hand, are compatible with observations for a wide range of parameters. Finally, definitive conclusions cannot be reached on magnetospheric models, since their localization and beaming properties are not well understood.

description: The occurrence of pesticide residues in bananas imported from Ecuador and the Philippines into Saudi Arabia was investigated. Eighty-seven banana samples were purchased from various supermarkets around the country. The conventional QuEChERS method was used to extract 294 pesticides in whole bananas and the analysis was carried out using LC-MS/MS and GC-MS/MS. In total, nine pesticides were detected of which azoxystrobin, carbendazim, chlorpyrifos, imazalil, and thiabendazole were the most frequently found in bananas from both countries. The levels of these pesticides were complaint according to the Saudi Food & Drug Authority’s (SFDA) maximum residue levels (MRLs), therefore they cannot be considered a public health problem. Detectable residues of these agrochemicals show that they are used extensively in banana cultivation. The Ecuadorian Agency for Agricultural Quality Assurance (Agrocalidad) and the Saudi Ministry of Environment, Water and Agriculture (MEWA) prohibit the use of carbendazim in agriculture, while the Filipino Fertiliser and Pesticide Authority (FPA) allows its use. A legislative comparison of pesticide approval status revealed a lack of consensus between banana exporting and importing countries that could affect food safety and trade.

description: We report on a study of pi and eta decays of strange baryon resonances within relativistic constituent-quark models based on one-gluon-exchange and Goldstone-boson-exchange dynamics. The investigations are performed in the point form of Poincare-invariant relativistic quantum mechanics with a spectator-model decay operator. The covariant predictions of the constituent-quark models underestimate the experimental data in most cases. These findings are congruent with an earlier study of nonstrange baryon decays in the light-flavor sector. We also consider a nonrelativistic reduction of the point-form spectator model, which leads to the decay operator of the elementary emission model. For some decays the nonrelativistic results differ substantially from the relativistic ones and they exhibit no uniform behavior as they scatter above and below the experimental decay widths.

description: This initial study aimed to determine the concentrations of perfluorooctane sulphonate (PFOS) and perfluorooctanoic acid (PFOA) in seafood, bottled drinking water, and surface and tap water collected from Map Ta Phut Industrial Estate in Rayong province, Thailand. Samples were collected during dry (January) and wet (June) seasons, 2019. The perfluorinated compounds were cleaned up by solid phase extraction and analysed by ultra-performance liquid chromatography–tandem mass spectrometry with stable isotopic labelled internal standards (13C8–PFOS and 13C8–PFOA). This study reports concentrations of PFOS and PFOA in seafood at levels between 29–6724 and <48–421 ng/kg wet weight, respectively. Surface water samples from rivers and the coastal sea had PFOS and PFOA between 0.60–465.65 and <0.25–59.29 ng/L, respectively. Contamination of PFOS and PFOA in bottled drinking water (<0.125–0.454 and <0.25–0.621 ng/L, respectively) did not exceed the USEPA standard of 70 ng/L. Concentrations of PFOS and PFOA in seafood and water samples between seasons did not show any definite trend. Seafood dietary assessments of PFOS exposure in the seafood eater population raised a health concern, as the exposure exceeded the latest EFSA tolerable weekly intake value for PFAS mixtures (4.4 ng/kg body weight/week). Therefore, environmental and food samples from Map Ta Phut area should be closely monitored to ensure the safety of people living in and around this area.

description: When classifying point clouds, a large amount of time is devoted to the process of engineering a reliable set of features which are then passed to a classifier of choice. Generally, such features - usually derived from the 3D-covariance matrix - are computed using the surrounding neighborhood of points. While these features capture local information, the process is usually time-consuming, and requires the application at multiple scales combined with contextual methods in order to adequately describe the diversity of objects within a scene. In this paper we present a 1D-fully convolutional network that consumes terrain-normalized points directly with the corresponding spectral data,if available, to generate point-wise labeling while implicitly learning contextual features in an end-to-end fashion. Our method uses only the 3D-coordinates and three corresponding spectral features for each point. Spectral features may either be extracted from 2D-georeferenced images, as shown here for Light Detection and Ranging (LiDAR) point clouds, or extracted directly for passive-derived point clouds,i.e. from muliple-view imagery. We train our network by splitting the data into square regions, and use a pooling layer that respects the permutation-invariance of the input points. Evaluated using the ISPRS 3D Semantic Labeling Contest, our method scored second place with an overall accuracy of 81.6%. We ranked third place with a mean F1-score of 63.32%, surpassing the F1-score of the method with highest accuracy by 1.69%. In addition to labeling 3D-point clouds, we also show that our method can be easily extended to 2D-semantic segmentation tasks, with promising initial results.
title: Peer review and competitive selection of marine RTD proposals for public funding in Spain: views from management and user sides

description: No abstracts are to be cited without prior reference to the author.Scientific excellence and potential societal benefits are key elements in most research and technological development (RTD) programs. Marine research in Spain, largely supported by public funds, showed a paradigmatic rapid development in the last decades. The establishment of the Marine Science and Technology Program (CYTMAR) in 1995, the growth of the oceanographic fleet and Marine Science Colleges at several universities were instrumental in this process. In addition, most Regional Councils in coastal regions also initiated their own Marine RTD programs. Selection of a growing number of proposals, most of them of multidisciplinary nature, is achieved by careful screening and review. At national level the selection process is made in two steps, one for peer-review on proposals on a one-by-one basis, and a second strategic review where proposals were ranked according to their contribution to specific program objectives. Independent expert review in step one is organized through the National Agency for Evaluation and Prospective (ANEP), while the strategic ranking is made by experts convened by the funding agency. Members of both agencies participate in the committee for final selection of proposals for funding. This process is generally simplified to one independent evaluation step in case of Regional Council programs. Among the benefits of the selection process for the funding agency are the independence of external reviews, and the balance between specialist and generalist experts. The two step evaluation also minimized the risk for conflicts of interest of reviewers in the proposals. Disadvantages of the process, for both funding agencies and researchers, are the long delays between project calls and final selection, and potential underestimation of multidisciplinary proposals.

description: Abstract: "We develop a general thermodynamical description of an evolving interface appropriate to situations far from equilibrium. The theory represents a broad departure from theories based on classical nonequilibrium thermodynamics, as we do not assume a linear relationship between fluxes and forces, and we do not limit our theory to small departures from equilibrium. Further, we allow for diffusion in both phases without an assumption of steady-state diffusion in the bulk material; we allow the composition of material transferred across the interface to differ from the compositions of either phase, with solute drag included as a special case; and we allow for heat flow in both phases. As an application of the general theory, we develop linearized interface conditions for an evolving interface."

description: Understanding and control of the spin relaxation time $T_1$ is among the key challenges for spin based qubits. A larger $T_1$ is generally favored, setting the fundamental upper limit to the qubit coherence and spin readout fidelity. In GaAs quantum dots at low temperatures and high in-plane magnetic fields $B$, the spin relaxation relies on phonon emission and spin-orbit coupling. The characteristic dependence $T_1 \propto B^{-5}$ and pronounced $B$-field anisotropy were already confirmed experimentally. However, it has also been predicted 15 years ago that at low enough fields, the spin-orbit interaction is replaced by the coupling to the nuclear spins, where the relaxation becomes isotropic, and the scaling changes to $T_1 \propto B^{-3}$. We establish these predictions experimentally, by measuring $T_1$ over an unprecedented range of magnetic fields -- made possible by lower temperature -- and report a maximum $T_1 = 57\pm15$ s at the lowest fields, setting a new record for the electron spin lifetime in a nanostructure.

description: As the burden of diabetes continues to rise across the world, the role of nurses becomes increasingly important in diabetes management. The findings suggest that families can play an essential role in supporting patients. Nurse-led Family-based (NLFB) intervention is an important area to study in Bahrain due to the established nursing workforce and family connectedness and limited relevant research. In addressing the research question (i.e. what are the effective components of a NLFB intervention for adults with T2DM?), the PhD utilized 4 research elements (i.e. Cochrane systematic review, a qualitative study, intervention protocol development (IPD), and a Delphi study) guided by the Behavior Change Wheel (BCW) theory within the overarching Medical Research Council (MRC) framework.The Cochrane systematic review and the qualitative element establishes the literature foundation for developing a NLFB intervention. The intervention development element utilizes the BCW theory. The Delphi element obtains priority tasks of the NLFB intervention.The PhD study ultimately led to the development of a novel NLFB intervention that is evidence-based, theoretically informed, and culturally sensitive.The PhD results found a significant mean difference of HbA1c (P0.003) in the family-based intervention compared to usual care. The findings of both the qualitative, and IPD elements confirmed knowledge and training importance for the NLFB intervention and diabetes. The outcomes.The intervention development designed an intervention protocol including 15 tasks. Over 90% of nurses prioritized 15 tasks of the NLFB protocol in three rounds of iteration. The PhD study indicates that the nurse-led care was not fully understood and that nurses tended to favor the multidisciplinary team over the nurse-led approach. The study found that nurse-led approach is not mutually exclusive to the multidisciplinary team. Instead, nurse-led care was found inclusive within the multidisciplinary team. The compiled findings indicated favoring the family-based intervention, with uncertainty around the nurse-led roles in diabetes care. Such findings suggest the need for enhanced nursing capacity building that could have a positive impact on nurses’ role, thus improve diabetes care.

description: We report on a study of thermal Hall conductivity k_xy in the superconducting state of CeCoIn_5. The scaling relation and the density of states of the delocalized quasiparticles, both obtained from k_xy, are consistent with d-wave superconducting symmetry. The onset of superconductivity is accompanied by a steep increase in the thermal Hall angle, pointing to a striking enhancement in the quasiparticle mean free path. This enhancement is drastically suppressed in a very weak magnetic field. These results highlight that CeCoIn_5 is unique among superconductors. A small Fermi energy, a large superconducting gap, a short coherence length, and a long mean free path all indicate that CeCoIn_5 is clearly in the superclean regime (E_F/Delta<
