description: γ-aminobutyric acid aminotransferase (GABA-AT) is a pyridoxal 5′-phosphate (PLP)-dependent enzyme which degrades γ-aminobutyric (GABA) in the brain. GABA is an important inhibitory neurotransmitter that plays important neurological roles in the brain. Therefore, GABA-AT is an important drug target which regulates the GABA level. Novel and potent drug development to inhibit GABA-AT is still very challenging task. In this study, we aimed to devise novel and potent inhibitors against GABA-AT using computer-aided drug design (CADD) tools. However, the human GABA-AT crystal structure is not available yet, and we built the 3D structure of human GABA-AT based on the crystal structure of pig’s liver (Sus Scrofa) enzyme as a template. The generated model was validated with numerous tools such as ProSA and PROCHECK. A set of selected well-known inhibitors have been tested against the modeled GABA-AT. Molecular docking studies have been accomplished via application of Genetic Optimization for Ligand Docking (GOLD), Vina and Autodock 4.2 software to search for potent inhibitors. The best two candidate inhibitors have been computationally examined for absorption, distribution, metabolism, elimination and toxicity descriptors (ADMET) and Lipinski’s rule of 5. Lastly, molecular dynamics (MD) simulations were carried out to inspect the ligands’ binding mode and stability of the active site of human GABA-AT over time. The top ranked ligands exhibited reliable stability throughout the MD simulation. The selected compounds are promising candidates and might be tested experimentally for the inhibition of human GABA-AT enzyme. Communicated by Ramaswamy H. Sarma

description: We develop a method for solving mathematical models of messenger RNA (mRNA) translation based on the totally asymmetric simple exclusion process (TASEP). Our main goal is to demonstrate that the method is versatile and applicable to realistic models of translation. To this end we consider the TASEP with codon-dependent elongation rates, premature termination due to ribosome drop-off and translation reinitiation due to circularisation of the mRNA. We apply the method to the model organism {\it Saccharomyces cerevisiae} under physiological conditions and find excellent agreements with the results of stochastic simulations. Our findings suggest that the common view on translation as being rate-limited by initiation is oversimplistic. Instead we find theoretical evidence for ribosome interference and also theoretical support for the ramp hypothesis which argues that codons at the beginning of genes have slower elongation rates in order to reduce ribosome density and jamming.

description: This paper measures the impact of year one of the Millennium Challenge Corporation’s Rural Business Development program for small rice farming households on the Pacific Coast of Nicaragua. The program was rolled out in the 2009-2010 agricultural year, which was the driest year on record in the region, likely due to an El Niño event. Estimated impacts show that the program at best had no effect, and at worst led to a 10 percent reduction in yields. These impacts are estimated using an econometric model which uses selection on observables as its identifying assumption, and robustness checks suggest that this is a reasonable approach in this case. Inference accounts for spatial correlation across households of the unobserved determinants of agricultural outcomes. The program appears to have been almost exclusively focused on increasing yields through better and greater application of chemical fertilizers, and minimization of losses in the post-harvest stages of production. If the pessimistic estimates of program effects are true, then the program could have been improved by incorporating risk management strategies into extension advice. On the other hand, farmers may be well insured against climatic risk, in which case they may have selected into the program knowing that they would be trading greater risk for higher expected returns. Survey data offers some evidence that the latter is indeed the case.

description: Long-term exposure to benzodiazepines for the treat- ment of anxiety can cause dependence and tolerance, which may lead to addiction. Alternative anxiety treat- ments that use bioactive substances found in organic ex- tracts obtained from algae have been considered. This research explores the possible anxiolytic effects of brown algae crude extracts of Stypopodium zonale in Drosoph- ila melanogaster using a dark/light box test. We hypoth- esize that D. melanogaster, upon consumption of food containing the crude extract derived from Stypopodium zonale, will exhibit less anxiety-related behaviors. To test our hypothesis, an organic extract of S. zonale brown al- gae was isolated and dissolved in 15% dimethyl sulfox- ide (DMSO). The crude extract was administered in the food of wild-type, developing and adult D. melanogaster subjected to a dark/light box test. The control group con- sisted of D. melanogaster exposed to regular food. The amount of time the flies spent on both sides of the box was recorded. Results show that Drosophila exposed to the extract showed less anxiety-related behaviors when compared to the control group. In conclusion, the crude organic S. zonale extract seemed to exert anxiolytic ef- fects in an anxiety model of D. melanogaster. This project is a step in the future potential use of specific or combined metabolites of brown algae extracts as a pharmacological alternative for the treatment of anxiety disorders.
Precise Critical Exponents of the O(N)-Symmetric Quantum field Model using Hypergeometric-Meijer Resummation

description: In this work, we show that one can select different types of Hypergeometric approximants for the resummation of divergent series with different large-order growth factors. Being of $n!$ growth factor, the divergent series for the $\varepsilon$-expansion of the critical exponents of the $O(N)$-symmetric model is approximated by the Hypergeometric functions $_{k+1}F_{k-1}$. The divergent $_{k+1}F_{k-1}$ functions are then resummed using their equivalent Meijer-G function representation. The convergence of the resummation results for the exponents $ν$,\ $η$ and $ω$ has been shown to improve systematically in going from low order to the highest known six-loops order. Our six-loops resummation results are very competitive to the recent six-loops Borel with conformal mapping predictions and to recent Monte Carlo simulation results. To show that precise results extend for high $N$ values, we listed the five-loops results for $ν$ which are very accurate as well. The recent seven-loops order ($g$-series) for the renormalization group functions $β,γ_{ϕ^2}$ and $γ_{m^2}$ have been resummed too. Accurate predictions for the critical coupling and the exponents $ν$, $η$ and $ω$ have been extracted from $β$,$γ_{ϕ^2}$ and $γ_{m^2}$ approximants.
Comment on form factor shape and extraction of |V_ub| from B --> pi l nu

description: We point out that current experimental data for partial B --> pi l nu branching fractions reduce the theoretical input required for a precise extraction of |V_ub| to the form factor normalization at a single value of the pion energy. We show that the heavy-quark expansion provides a bound on the form factor shape that is orders of magnitude more stringent than conventional unitarity bounds. We find |V_ub| = (3.7 +/- 0.2 +/- 0.1) x [0.8/F_+(16 GeV^2)]. The first error is from the experimental branching fractions, and the second is a conservative bound on the residual form factor shape uncertainty, both of which will improve with additional data. Together with current and future lattice determinations of the form factor normalization this result gives an accurate, model independent determination of |V_ub|. We further extract semileptonic shape observables such as |V_ub F_+(0)| = 0.92 +/- 0.11 +/- 0.03 and show how these observables can be used to test factorization and to determine low-energy parameters in hadronic B decays.

description: In an initial exploration of virtual reality (VR) for assessing speech recognition and listening effort in realistic environments, pupillometry data collected via a consumer Vive Pro-Eye headset were compared with data obtained via an Eyelink 1000 system, from the same normally-hearing participants presented with similar non-spatialized auditory stimuli. Vive testing used a custom platform based on Unity for video playback and MaxMSP for headphones-based audio rendering and overall control. For Eyelink measurements, head movements were minimized by a chin rest and participants fixated on a cross presented on a grey screen. No such constraints were present for Vive measurements which were conducted both using a 360° cafe video and with a uniformly grey visual field. Participants identified IEEE sentences in babble at two signal-to-noise ratios (SNRs). The lower SNR (-3 dB) produced around 65% word recognition, while performance for the higher SNR (+6 dB) was at ceiling. As expected, pupil dilation was greater for the lower SNR, indicating increased listening effort. Averaged across participants, pupil data were very similar across systems, and for the Vive, across the different visual backgrounds, thereby supporting the idea that VR systems have the potential to provide useful pupillometric listening effort data in realistic environments.

Ongoing experiments, conducted solely in VR and using spatialised sound, examine the effects of incorporating different aspects of realistic situations. In the aforementioned café video three computer monitors, each associated with a particular talker, are visible on tables. In one condition, as above, target sentences from a single talker are presented audio-only. In a second single-talker condition, a video of the talker reading the target sentence is also presented. In a third condition the target talker varies quasi-randomly across trials. A visual cue presented 2s prior to the target video allows the participant to orient to the correct screen. In each visual condition, target sentences are presented against a background of café noise plus additional babble at two SNRs, differing by 9 dB. Comparison across conditions will be informative of the extent to which pupillometry data may be affected by factors such as dynamic changes in visual background and head movements of the type typically involved in multi-talker conversations.

description: For more than thirty years, studies about the effect of the exchange rate on exports have been conducted. However, few have considered the combined effect of the exchange rate on imported inputs into the agricultural system and the exports of final agricultural products those inputs produce. A current concern is for the net effect as the total value and quantity of inputs imported has increased. This research examines the effect of exchange rate changes on imported inputs into the corn, wheat, and beef cattle production systems. Effects on cost of production budgets are calculated, examining affects on profitability. Vector Autoregression (VAR) and Bayesian Averaging of Classical Estimates (BACE) models were estimated to evaluate those effects. Daily and weekly price data were used for corn, wheat, feeder steers, ethanol, diesel, ammonia, urea, di-ammonium phosphate, and the exchange rate. A VAR model was estimated to model the relationship between the variables. After having incongruous test results in determining the lag length structure it was decided that a BACE model would be approximated. After estimating the BACE model the price responses of the commodities to the exchange rates was estimated. The price responses were used in demonstrating the effect of the exchange rate on a producer’s profitability. It was determined that, generally, a strengthening exchange rate has a negative impact on prices. It was also found that the exchange rate has a greater impact on prices now than it did 14 years ago, implying that the exchange rate now has a greater affect on profitability. A one percent increase in the value of the dollar led to a decline in profitability ranging from $0.02/bu in wheat to $0.56/cwt in feeder steers. However, agricultural producers should not be overly concerned about a lower valued dollar from the perspective of their agricultural business.

description: We use microwave induced adiabatic passages for selective spin flips within a string of optically trapped individual neutral Cs atoms. We position-dependently shift the atomic transition frequency with a magnetic field gradient. To flip the spin of a selected atom, we optically measure its position and sweep the microwave frequency across its respective resonance frequency. We analyze the addressing resolution and the experimental robustness of this scheme. Furthermore, we show that adiabatic spin flips can also be induced with a fixed microwave frequency by deterministically transporting the atoms across the position of resonance.

description: This paper examines the relationship between household food security status, SNAP participation, and time used in food preparation and acquisition. Using the American Time Use Survey linked with the Current Population Survey's Food Security Supplement, we find that food insecurity and SNAP participation are positive predictors of number of minutes single adult households use in food preparation. Meanwhile, SNAP participation is a negative predictor of food acquisition. Although these results do not imply a causal relationship, they do reveal reflect that food insecure households and households that participate in the SNAP program use time differently than food secure and non-participating households.

We show that weak ferromagnetism of the Dzyaloshinskii-Moriya type occurs in this material, and we analyze the coupling between the resulting magnetization and the structural distortions. We explore the possibility of electric-field-induced magnetization reversal and show that, although it is unlikely to be realized in BiFeO_3, it is not in general impossible. Finally we outline the conditions that must be fulfilled to achieve switching of the magnetization using an electric field.

The coexistence of different quantum vacua is perhaps regulated by the exchange of global fermionic charges or by fermion zero modes on the phase boundary. An example would be a static de-Sitter Universe embedded in an asymptotically flat spacetime.

description: What do Cyberpunk and AI Ethics have to do with each other? Cyberpunk is a sub-genre of science fiction that explores the post-human relationships between human experience and technology. One similarity between AI Ethics and Cyberpunk literature is that both seek to explore future social and ethical problems that our technological advances may bring upon society. In recent years, an increasing number of ethical matters involving AI have been pointed and debated, and several ethical principles and guides have been suggested as governance policies for the tech industry. However, would this be the role of AI Ethics? To serve as a soft and ambiguous version of the law? We would like to advocate in this article for a more Cyberpunk way of doing AI Ethics, with a more democratic way of governance. In this study, we will seek to expose some of the deficits of the underlying power structures of the AI industry, and suggest that AI governance be subject to public opinion, so that good AI can become good AI for all.

description: As the COVID-19 outbreak is developing the two most frequently reported statistics seem to be the raw confirmed case and case fatalities counts. Focusing on Italy, one of the hardest hit countries, we look at how these two values could be put in perspective to reflect the dynamics of the virus spread. In particular, we find that merely considering the confirmed case counts would be very misleading. The number of daily tests grows, while the daily fraction of confirmed cases to total tests has a change point. It (depending on region) generally increases with strong fluctuations till (around, depending on region) 15th-22nd March and then decreases linearly after. Combined with the increasing trend of daily performed tests, the raw confirmed case counts are not representative of the situation and are confounded with the sampling effort. This we observe when regressing on time the logged fraction of positive tests and for comparison the logged raw confirmed count. Hence, calibrating model parameters for this virus's dynamics should not be done based only on confirmed case counts (without rescaling by the number of tests), but take also fatalities and hospitalization count under consideration as variables not prone to be distorted by testing efforts. Furthermore, reporting statistics on the national level does not say much about the dynamics of the disease, which are taking place at the regional level. These findings are based on the official data of total death counts up to 15th April 2020 released by ISTAT and up to 10th May 2020 for the number of cases. In this work we do not fit models but we rather investigate whether this task is possible at all. This work also informs about a new tool to collect and harmonize official statistics coming from different sources in the form of a package for the R statistical environment and presents the COVID-19 Data Hub.

Not Black and White?: Disciplinary Regulation of Doctors Convicted of Child Pornography Offences in Australia

description: Between 2006–19, eight doctors who were registered to practise medicine in Australia were convicted of child pornography offences. Despite finding that those medical practitioners' conduct was extremely serious, disciplinary decision-makers permitted seven of them to continue or, after a period of suspension of their registration, return to practising medicine, albeit subject to conditions. The decision-makers whose reasons for decision are published indicated that they strove to achieve the appropriate objective of protecting the public, but they reached their determinations to some extent in different ways from one another and, in some instances, on the basis of matters that were unhelpful in identifying which determinations would best safeguard the community. Further, they did not all provide thorough, cogent reasons for their decisions. This article analyses the matters to which these decision-makers had regard. It then recommends that Australian legislatures and regulators of the medical profession provide guidance regarding decision-making in disciplinary proceedings where doctors have committed child pornography offences. These proposals seek to ensure that disciplinary decision-makers safeguard the community in a consistent manner, and assure the public and the medical profession that they have done so.

description: The threats posed by botnets in the cyberspace continue to grow each day and it has become very hard to detect or infiltrate the cynicism of bots. This, is owing to the fact, that, the botnet developers each day, keep changing the propagation and attack techniques. Currently, most of these attacks have been centered on stealing computing energy, theft of personal information and Distributed Denial of Service (DDoS) attacks. In this paper, the authors propose a novel technique that uses the Non-Deterministic Polynomial-Time Hardness (NP-Hard Problem) based on the Traveling Salesperson Person (TSP) that depicts that a given bot, bj, is able to visit each host on a network environment, NE, and then it returns to the botmaster, in form of instruction(command), through optimal minimization of the hosts that are (may) be attacked. Given that bj represents a piece of malicious code and TSP-NP Hard Problem, which forms part of combinatorial optimization, the authors present this as an effective approach for the detection of the botnet. It is worth noting that the concentration of this study is basically on the centralized botnet architecture. This holistic approach shows that botnet detection accuracy can be increased with a degree of certainty and potentially decrease the chances of false positives. Nevertheless, a discussion on the possible applicability and implementation has also been given in this paper.

description: We consider systems of ordinary differential equations with multiple scales in time. In general, we are interested in the long time horizon of a slow variable that is coupled to solution components that act on a fast scale. Although the fast scale variables are essential for the dynamics of the coupled problem, they are often of no interest in themselves. Recently we have proposed a temporal multiscale approach that fits into the framework of the heterogeneous multiscale method and that allows for efficient simulations with significant speedups. Fast and slow scales are decoupled by introducing local averages and by replacing fast scale contributions by localized periodic-in-time problems. Here, we generalize this multiscale approach to a larger class of problems but in particular, we derive an a posteriori error estimator based on the dual weighted residual method that allows for a splitting of the error into averaging error, error on the slow scale and error on the fast scale. We demonstrate the accuracy of the error estimator and also its use for adaptive control of a numerical multiscale scheme.

description: We present a calculation of $P\to γ^{(\ast)}γ^{(\ast)}$ processes, where $P=π^0,\ η,\ η'$, at the one-loop level up to and including next-to-next-to-leading order (NNLO) in large-$N_c$ chiral perturbation theory. The results are numerically evaluated successively at LO, NLO, and NNLO. The appearing low-energy constants are determined through fits to the available experimental data. We investigate the decay widths to real photons, the single-virtual transition form factors, and the widths of $P\toγl^+l^-$, where $l=e,\ μ$. Furthermore, we provide results for the slopes and curvatures of the transition form factors.

description: We present angle-resolved photoemission spectroscopy results for thin films of the three-dimensional manganese perovskite La$_{1-x}$Sr$_{x}$MnO$_{3}$. We show that the transition temperature ($T_c$) from the paramagnetic insulating to ferromagnetic metallic state is closely related to details of the electronic structure, particularly to the spectral weight at the ${\bf k}$-point, where the sharpest step at the Fermi level was observed. We found that this ${\bf k}$-point is the same for all the samples, despite their different $T_c$. The change of $T_c$ is discussed in terms of kinetic energy optimization. Our ARPES results suggest that the change of the electronic structure for the samples having different transition temperatures is different from the rigid band shift.

description: A new and efficient approach for the synthesis of thioflavones and thioaurones by competitive cascade cyclization of 2′-tosyloxychalcones has been developed. 2′-Tosyloxychalcones were smoothly converted into thioflavones and thioaurones by incorporation of sulfur atom using elemental sulfur and triethylamine in DMSO with good yields. The advantages of the methodology are the formation of both thioflavones and thioaurones in a single step. Easily accessible substrates, mild reaction conditions and compatibility with a broad range of functional groups make this protocol clean and inexpensive.

description: What exactly is the national university and how could we study it? What uses could such a concept have in the conceptual toolkit of higher education? Building on the rich intellectual tradition on the idea of the university, this dissertation mainly encompasses the disciplines of political science and higher education to explore a distinct organizational form that is frequently located at the apex of education systems worldwide. Such a subject is intimately intertwined with dynamics of power within inherently inequitable societies placed within world-spanning interrelationships and configurations. This cumulus consists of three connected papers that provide the intellectual scaffolding that underpins the concept of the national university. The first paper, a thematic analysis of texts from the formative period of the organizational form in question, provides the parameters and necessary elements to delineate the concept. From this study, the terrain is mainly argued to be defined by two contrasting objects that refer to the national university—a narrow de jure construction and an expansive de facto category. The following papers then study each object. On one hand, the second paper on the de jure national university uses historical and organizational data to infer factors and motivations that led to its global spread. Results suggest that national universities were founded mostly by newly-established countries motivated by internal stability and geopolitical competition. On the other hand, the third study on de facto national universities explores how political elites are increasingly funneled into particular universities over time. Results reveal patterns of movement of individuals between subnational states and higher education institutions that both indicate political concentration over time. The analysis of educational paths of political elites point to the ability of institutions to attract students beyond their state as a way to identify de facto national universities. The dissertation concludes with future trajectories that this research agenda could undertake.
Noiseless Linear Amplifiers for Multimode States

description: The entanglement structure between different frequency components within broadband quantum light pulses, forged at entanglement creation, represents a promising route to the practical delivery of many multipartite quantum information applications. However, the scalability of such applications is largely limited by the entanglement decoherence caused by photon loss. One promising method to combat such losses is noiseless linear amplification. However, while there have been various procedures that implement noiseless linear amplification on single-mode states, no realization has thus far been proposed for noiseless linear amplification on quantum states carrying a multimode structure. In this work we close this gap, proposing a novel Noiseless Linear Amplifier (NLA) with Photon Catalysis (PC), namely, the PC-NLA. Constructing a multimode version of an existing NLA that uses Quantum Scissors (QS), the QS-NLA, we then show how the PC-NLA is compatible with the QS-NLA, even though the former uses half the physical resources of the latter. We then apply our newly developed multimode NLA frameworks to the problem of Continuous-Variable (CV) entanglement distillation, determining how the multimode structure of the entanglement impacts the performance of the NLAs. Different from single-mode NLA analyses, we find that a multimode NLA is only effective as a CV entanglement distillation strategy when the channel loss is beyond some threshold - a threshold largely dependent on the multimode structure. The results provided here will be valuable for real-world implementations of multipartite quantum information applications that utilize complex entanglement structure within broadband light pulses.

description: Intercalation of lithium atoms between layers of 2D materials can alter their atomic and electronic structure. We investigate effects of Li intercalation in twisted bilayers of the transition metal dichalcogenide MoS$_2$ through first-principles calculations, tight-binding parameterization based on the Wannier transformation, and analysis of moiré band structures through an effective continuum model. The energetic stability of different intercalation sites for Li between layers of MoS$_2$ are classified according to the local coordination type and the number of vertically aligned Mo atoms, suggesting that the Li atoms will cluster in certain regions of the moiré superlattice. The proximity of a Li atom has a dramatic influence on the interlayer interaction between sulfur atoms, deepening the moiré potential well and leading to better isolation of the flat bands in the energy spectrum. These results point to the usefulness for the use of chemical intercalation as a powerful means for controlling moiré flat-band physics in 2D semiconductors.

description: Os novos arranjos territoriais que passaram a figurar a partir do final do século XX, estão causando mudanças em diferentes escalas geográficas dos sistemas socioeconômicos. No caso da agricultura, as iniciativas de âmbito local têm surgido como uma resposta às imposições oriundas da produção global de commodities. Produtos típicos ou tradicionais tem sido oferecidos no mercado para satisfazer consumidores que valorizam aspectos como: cultura, tradição, paisagem e cuidados ambientais, criando laços de identidade com o produto consumido. Neste contexto é que surge o SIAL (sistemas agroalimentares localizados), como uma abordagem capaz de analisar as relações entre as atividades agroalimentares constituídas territorialmente, pela valorização e uso dos recursos locais. Com base nesta abordagem o propósito deste estudo é averiguar se determinadas características que configuram um SIAL podem ser identificadas na produção familiar de morango, no Vale do Caí, no Rio Grande do Sul. Como resultado deste estudo pode-se averiguar que o SIAL se configura pelo uso de determinados ativos territoriais locais mobilizados pelos agricultores familiares que estão gerando uma identidade para o local atrelada ao morango produzido no Vale do rio Caí.------------------------------------------New territorial arrangements that appeared from the end of the XXth century on are causing changes in different geographical scales of socioeconomic systems. In the case of agriculture, local initiatives have appeared as an answer to impositions of global commodities production. Typical or traditional products have been offered in markets to satisfy consumers that valorize aspects as: culture, tradition, landscape and environmental care, creating links with the consumed product. In this context emerges SIAL (agroalimentar localized systems) as an approach able to analyze relations among agroalimentar activities territorially constituted and local resources use. Based upon this approach the objective of this study is to check if determined characteristics that constitute an SIAL may be identified in familiar small farmers strawberry production, in Cai River Valley, Rio Grande do Sul State. As a result of this study it is possible to see that SIAL is configurated by the use of determined local territorial stocks mobilized by familiar small farmers that are generating an identity for the local related to strawberries produced in Cai River Valley.
