description: In an attempt to describe how low-energy electrons (LEEs) damage the polypeptide chain at disulfide bridges, ab initio electronic structure estimates on LEE interactions with cysteine-cysteine (Cys-Cys) disulfide bond model have been performed. Here, the fundamental mechanisms in LEE impression on S-S and C-S bond ruptures in the Cys-Cys model have been discussed. The electronic energy was calculated using the MP2 method with a Hartree–Fock exchange during the SCF and the Møller–Plesset correlation energy correction on the converged HF orbitals with 6-311++G(d,p) atomic orbital basis set. Further, six more sets of diffuse s and p functions with extra basis on the sulfur and relevant carbon atoms were used to describe the added electron to located away as much as possible from the nuclei in anions. The bonds rupture mechanisms involve the primary placement of LEEs to the π* orbital of the model to construct the shape-resonance state following by an adiabatic or nonadiabatic electron migration to either S-S or C-S bond σ* orbital. The formed radical anion undergoes S-S or C-S bonds cleavage by energy barriers of ca. 5.68 and 9.19 kcal/mol, respectively, to produce either (2-amino-2-carboxyethyl) sulfanyl (cysteine radical), aziridine-2-carboxylic acid or mercapto-L-cysteine lesions. In SMD solvent, calculations suggest electronically stable of the formed π* and σ* states by solvation, something that induces either S-S or C-S bond break even when the electron energy is near zero. The required barrier energy of only 0 to < 0.4 eV indicates a high kinetic favorable fragmentation for involved sulfur polypeptides with LEEs. Communicated by Ramaswamy H. Sarma
A category theoretic approach to extensions of Banach algebras
Creators: name: Menez, Christopher
Publisher: name: Lancaster University
Year: 2018

description: This thesis aims to generalise Busby’s framework for studying extensions of C∗-algebras, to the Banach-algebraic setting, without requiring admissibility assumptions on extensions. In the case where the canonical embedding ιJ of a faithful Banach algebra J into its multiplier algebra MJ has closed range, we classify all extensions of an arbitrary Banach algebra B by J. This is done by presenting two categories, one of extensions and another of Busby maps, and proving that these categories are equivalent. We then consider cases where the canonical embedding of J need not have closed range, and provide some partial results in such cases under the extra assumption of a bounded linear lift for a given Busby map. These results are then applied to several examples, where we also compute explicit multiplier norms for MJ when J is a maximal ideal in Ck([−1, 1]). To go further, we study the quotient MJ/ιJ (J) not as a seminormed space but as an object in a suitable derived category. To lay the necessary foundations, the derived category construction of Grothendieck and Verdier is applied to the category of Banach spaces and bounded linear maps. Using this framework, we introduce a class of “Q-Busby maps” from an arbitrary Banach algebra B into MJ/ιJ (J), and obtain a restricted version of Busby’s original correspondence, applicable whenever J is a faithful Banach algebra.

Parallel computation of data cubes
Creators: name: Momen-Pour, Soroush
Publisher: name: University of British Columbia
Year: 2009

description: Since its proposal, data cube has attracted a great deal of attention in both academic and industry research communities. Many research papers have been published about different issues related to data cubes and many commercial OLAP (On-Line Analytical Processing) systems have been released to market with data cube operations as their core functions. Several algorithms have been proposed to compute data cubes more efficiently. PIPESORT and PIPEHASH algorithms proposed by Agrawal et. al., OVERLAP algorithm proposed by Naughton et. al., Partitioned-Cube algorithm proposed by Ross et. al. and the Multi-way Array algorithm proposed by Naughton et. al. are the most significant ones. All of these algorithms are designed for implementation on sequential machines, however computing a data cube can be an expensive task. For some organizations it may take a very powerful computer working around the clock for a week to compute all the data cubes they may want to use. Application of parallel processing can speed up this process. Despite the popularity and importance of data cubes, very little research has been carried out on the parallel computation of them. The only parallel algorithm for computation of data cubes, which I am aware of, is the algorithm proposed by Goil et. al.. Their algorithm works for cases where the data set fits in main memory, however, real world data sets rarely fit in main memory. The wide spread availability of inexpensive cluster machines makes it possible to use parallel processing for computation of data cubes, even in small size firms and as a result there could be a real demand for efficient parallel data cube construction algorithms. I have designed and implemented two parallel data cube computation algorithms (Parallel Partitioned-Cube algorithm and Parallel Single-pass Multi-way Array algorithm) based on sequential algorithms proposed in literature. The former algorithm is classified as a ROLAP (Relational OLAP) algorithm and the second one is considered as a MOLAP (Multi-dimensional OLAP) algorithm.

description: The correlated 3d sulphide BaVS_3 is a most interesting compound because of the apparent coexistence of one-dimensional and three-dimensional properties. Our experiments explain this puzzle and shed new light on its electronic structure. High-resolution angle-resolved photoemission measurements in a 4eV wide range below the Fermi level explored the coexistence of weakly correlated a_1g wide-band and strongly correlated e_g narrow-band d-electrons that is responsible for the complicated behavior of this material. The most relevant result is the evidence for a_1g--e_g inter-band nesting condition.

description: The recent report of NANOGrav is gathering attention since its signal can be explained by the stochastic gravitational waves (GWs) with $Ω_{\rm GW}\sim 10^{-9}$ at $f\sim 10^{-8}$Hz. The PBH formation scenario is one of the candidates for the NANOGrav signal, which can simultaneously explain the observed $30 M_\odot$ black holes in the binary merger events in LIGO-Virgo collaboration. We focus on the type II axion-like curvaton model of the PBH formation. In type II model the complex field whose phase part is the axion rolls down from the origin of the potential. It is found that type II model achieves the broad power spectrum of the density perturbations and can simultaneously explain the LIGO-Virgo events and the NANOGrav signal. We also improve the treatment of the non-Gaussianity of perturbations in our model to accurately estimate the amplitude of the induced GWs.

description: In recent years, the field of ultra-cold atomic gases has rapidly evolved into a cornerstone of experimental quantum mechanics, with promising applications in precision sensing, quantum computing, and as platforms for tests of fundamental physics. Currently, ultracold quantum gases are prepared via the two-step process of laser and evaporative cooling. However, the latter an inherently lossy process, resulting in the lost of almost all (99.9%) of the initial atoms. Recently, advances in optical control technology have lead to considerable interest in an alternative, number-conserving procedure based upon principles of feedback cooling. Previous attempts to model feedback cooling of atomic gases have struggled to capture the complex quantum correlations induced by the measurement process, as well as finite temperature effects associated with thermal fluctuations. To this end, the applicability of feedback cooling to complex, multi-mode systems such as quantum gases is still an open question. In this thesis, a new field-theoretic technique based upon existing phase-space methods is developed for scalable numerical simulations of controlled quantum systems, and used to model feedback cooling of a Bose gas subject to periodic, non-destructive measurements via phase-contrast imaging. We check the validity of our approach in a two-mode system, which permits an exact solution due to its low-dimensional nature, and observe exceptional agreement across various moments of pseudo-spin operators. In addition, we discuss potential limitations of our approach, and propose comparisons with existing techniques such as the Number-Phase Wigner particle filter, which has been the leading choice for existing simulations of controlled quantum systems undergoing number-like measurements. Finally, we present preliminary results demonstrating successful cooling of a thermal state with low condensate fraction in a quasi-1D geometry, where we observe an increase of the condensate fraction from ffrac = 4.4 ± 0.2% to ffrac = 98.0 ± 0.2% over forty trap periods. To our knowledge, this is the first demonstration of successful cooling for a finite-temperature quantum field with particle numbers on the order of N ≈ 106 and low initial condensate fraction. We conclude with a discussion of the restrictions imposed by the dimensional reduction, and propose avenues for further investigations such as the incorporation of spontaneous emission effects, exotic feedback schemes, and simulation of experimentally realistic geometries.

description: Nonstoichiometric perovskite-related oxides (such as ferrites and cobaltites, etc.) are characterized by fast oxygen transport at ambient temperatures, which relates to the microstructural texturing of these materials, consisting wholly of nanoscale microdomains. We have developed an inhomogeneous diffusion model to describe the kinetics of oxygen incorporation into nanostructured oxides. Nanodomain boundaries are assumed to be the high diffusivity paths for oxygen transport whereas diffusion into the domains proceeds much slower. Using Laplace transform methods, an exact solution is found for a ramped stepwise potential, allowing fitting of the experimental data to theoretical curves (in Laplace transforms). A further model generalization is considered by introducing additional parameters for the size distribution of domains and particles. The model has been applied for qualitative evaluation of oxygen diffusion parameters from the data on wet electrochemical oxidation of nano-structured perovskite SrCo_0.5Fe_0.2Ta_0.3O_{3-y} samples.

description: Meson spectra given as fluctuations of a D7 brane are studied under the background driven by the dilaton. This leads to a dual gauge theory with quark confinement due to the gauge condensate. We find that the effect of the gauge condensate on the meson spectrum is essential in order to make a realistic hadron spectrum in the non-supersymmetric case. In the supersymmetric case, however, only the spectra of the scalars are affected, but they are changed in an opposite way compared to the non-supersymmetric case.

Assessing Quality of Answers to a Global Subjective Well-being Question through Response Times
Creators: name: Yan, Ting
Publisher: name: European Survey Research Association
Year: 2015
Subjects: subjective well-being; validity; reliability; response times

description: Many large-scale surveys measure subjective well-being (SWB) through a single survey item. This paper takes advantages of response time data to explore the relation between time taken to answer a single SWB item and the reliability and validity of answers to this SWB item. We found that reliability and validity of answers to the SWB item are low for respondents aged 70 and above and for respondents who took more time to answer the item. The findings indicate that longer time spent answering the single SWB item is associated with data of lower quality, suggesting that the longer response time is probably a result of people having difficulty answering the item. This paper provides another piece of evidence that the single-SWB-item approach may not be the best way to measure subjective well-being, especially for older respondents.

description: Purpose: Damaging the three-dimensional structure of a protein may lead to either inhibition or other more drastic changes in its specific functionality. In an attempt to describe how low-energy electrons (LEEs) damage the polypeptide chain at disulfide bridges, ab initio electronic structure estimates on LEE interactions with cysteine-cysteine (Cys-Cys) disulfide bond model have been performed.

In SMD solvent calculations suggest electronically stable of the formed π* and σ* states by solvation, something that induces either S-S or C-S bond break even when the electron energy is near zero eV. Conclusions: The required barrier energy of only 0 to <0.4 eV indicates a high kinetic favorable fragmentation for involved sulfur polypeptides with LEEs.

description: Straightlining, an indicator of satisficing, refers to giving the same answer in a series of questions arranged on a grid. We investigated whether straightlining changes with respondents’ panel experience in two open-access Internet panels in the Netherlands: the LISS and Dutch Immigrant panels. Specifically, we considered straightlining on 10 grid questions in LISS core modules (7 waves) and on a grid of evaluation questions in both the LISS panel (150+ waves) and the Dutch immigrant panel (50+ waves). For both core modules and evaluation questions we found that straightlining increases with respondents’ panel experience for at least three years. Straightlining is also associated with younger age and non-western 1st generation immigrants. Where straightlining was a plausible set of answers, prevalence of straightlining was much larger (15-40%) than where straightlining was implausible (

Uniqueness of extremal isolated horizons and their identification with horizons of all type D black holes

description: We systematically investigate axisymmetric extremal isolated horizons (EIHs) defined by vanishing surface gravity, corresponding to zero temperature. In the first part, using the Newman-Penrose and GHP formalism we derive the most general metric function for such EIHs in the Einstein-Maxwell theory, which complements the previous result of Lewandowski and Pawlowski. We prove that it depends on 5 independent parameters, namely deficit angles on the north and south poles of a spherical-like section of the horizon, its radius (area), and total electric and magnetic charges of the black hole. The deficit angles and both charges can be separately set to zero. In the second part of our paper, we identify this general axially symmetric solution for EIH with extremal horizons in exact electrovacuum Plebanski-Demianski spacetimes, using the convenient parametrization of this family by Griffiths and Podolsky. They represent all (double aligned) black holes of algebraic type D without a cosmological constant. Apart from a conicity, they depend on 6 physical parameters (mass, Kerr-like rotation, NUT parameter, acceleration, electric and magnetic charges) constrained by the extremality condition. We were able to determine their relation to the EIH geometrical parameters. This explicit identification of type D extremal black holes with a unique form of EIH includes several interesting subclasses, such as accelerating extremely charged Reissner-Nordstrom black hole (C-metric), extremal accelerating Kerr-Newman, accelerating Kerr-NUT, or non-accelerating Kerr-Newman-NUT black holes.

Evaluating a Modular Design Approach to Collecting Survey Data Using Text Messages

Subjects: modular survey design; survey methodology; survey nonresponse; text message surveys; total survey error; survey costs

description: This article presents analyses of data from a pilot study in Nepal that was designed to provide an initial examination of the errors and costs associated with an innovative methodology for survey data collection. We embedded a randomized experiment within a long-standing panel survey, collecting data on a small number of items with varying sensitivity from a probability sample of 450 young Nepalese adults. Survey items ranged from simple demographics to indicators of substance abuse and mental health problems. Sampled adults were randomly assigned to one of three different modes of data collection: a standard one-time telephone interview, a “single sitting” back-and-forth interview with an interviewer using text messaging, and an interview using text messages within a modular design framework. Respondents in the modular group were asked to respond (via text message exchanges with an interviewer) to only one question on a given day, rather than complete the entire survey. Both bivariate and multivariate analyses demonstrate that the two text messaging modes increased the probability of disclosing sensitive information relative to the telephone mode, and that respondents in the modular design group, while responding less frequently, found the survey to be significantly easier. Further, those who responded in the modular group were not unique in terms of available covariates, suggesting that the reduced item response rates only introduced limited nonresponse bias. Future research should consider enhancing this methodology, applying it with other modes of data collection (e.g., web surveys), and continuously evaluating its effectiveness from a total survey error perspective.

Diagnosis. A species of Johnius with the following combination of characters: snout steep, obtusely pointed; mouth small, inferior; moderate eye, 20 to 29% of HL; gill rakers moderately slender, about 1/2 length of gill filaments at angle of arch, 9 to 11 on lower limb of first gill arch; second anal spine length short, slender, about 25 to 34% of HL; and scales larges, 5 to 6 scale rows above lateral line (Hanafi et al., 2022).
Distribution. Western Pacific; Gulf of Thailand, Malaysia and Indonesia.
Remarks. Johnius heterolepis can be distinguished from most similar sympatric congener species, J. sasakii, by the snout pointed (snout blunt in sasakii) and the gill raker slender and count more higher (9 to 11 in heterolepis vs short, stiff, 8 to 10 in sasakii). Johnius heterolepis also is a common species, dominant and abundant especially concentrated in Sarawak states. It was collected at several sites of the Goebilt, Sarikei, and Bintulu.

Undercoverage and Nonresponse in a List-sampled Telephone Election Survey
Creators: name: Lipps, Oliver

Publisher: name: European Survey Research Association
Year: 2015

description: For landline telephone surveys in particular, undercoverage has been a growing problem. However, research regarding the relative contributions of socio-demographic bias and other composition effects is scarce. We propose to address this issue by analyzing an election survey which used a sample from a register-based sampling frame containing basic socio-demographic information and to which telephone numbers were subsequently matched. 
With respect to socio-demographic representation of the final sample, we find that difficult to match groups are also difficult to contact, while those who cooperate tend to have different characteristics. We find bias due to undercoverage to be of greater magnitude than noncontact bias, while noncooperation falls between the two. As for substantive variables, both additional efforts to match missing telephone numbers and the construction of better weights are successful in closing the gap between survey estimates of voting behavior and true values from the election results.

description: β-glucosidases (EC 3.2.1.21) have been described as essential to second-generation biofuel production. They act in the last step of the lignocellulosic saccharification, cleaving the β − 1,4 glycosidic bonds in cellobiose to produce two molecules of glucose. However, β-glucosidases have been described as strongly inhibited by glucose, causing an increment of cellobiose concentration. Also, cellobiose is an inhibitor of other enzymes used in this process, such as exoglucanases and endoglucanases. Hence, the engineering of thermostable and glucose-tolerant β-glucosidases has been targeted by many studies. In this study, we performed high sampling accelerated molecular dynamics for a wild glucose-tolerant GH1 β-glucosidase (Bgl1A), a wild non-tolerant (Bgl1B), and a set of glucose-tolerant Bgl1B’s mutants: V302F, N301Q/V302F, F172I, V227M, G246S, T299S, and H228T. Our results suggest that point mutations promissory to induce glucose tolerance trend to enhance the mobility of the flexible loops around the active site. Mutations affected B and C loops regions, and an αβ-hairpin motif between them. Conformational clusters and free energy landscape profiles suggest that the mobility acquired by mutants allows a higher closure of the substrate channel. This closure is compatible with a higher impedance for glucose entrance and stimulus of its withdrawal. Based on mutants’ structural analyses, we inferred that both the direct stereochemical effect on the glucose path and the changes in the mobility affect glucose tolerance. We hope these results be useful for the rational design of glucose-tolerant and industrially promising enzymes. Communicated by Ramaswamy H. Sarma

description: The work of Smyth, Dillman, Christian, and Stern (2006) and Smyth, Christian, and Dillman (2008) compares “yes/no” questions to “check all that apply” questions. They conclude that the “yes/no” format is preferable as it reflects deeper processing of survey questions. Smyth et al. (2008) found that the “yes/no” format performed similarly across telephone and web modes. In this paper we replicate their research and extend it by including a comparison with face-to-face in addition to telephone and web and by using probability samples of the general adult population. A cognitive interviewing follow-up was used to explore the quantitative findings. Our results suggest there are times when the “yes/no” format may not perform similarly across modes and that there may be factors which limit the quality of answers.

description: The non-polarized points (NPP) of the $Q$ and $U$ Stokes parameters of the CMB can be classified according to the geometry of the polarization field. We describe a procedure to identify these points in the pixelized sky and present the shape of the polarization angles in the vicinity of NPPs. We design a test of Gaussianity using the Kullback-Leibler divergence. We show that the total number density of non-polarized points of the E- and B-families is closely related to the presence of lensing and the tensor-to-scalar ratio $r$. We further show that in the absence of lensing, the total number of NPPs of all types does not depend on $r$, while the lensing effect removes this degeneracy. This analysis is applied to the CMB maps from the 2018 Planck release. We show that there is general consistency of SMICA and NILC maps compared to a reference set of Gaussian simulations. The strongest discrepancies are found in the Commander (with corresponding $p$-value $0.07$) and NILC ($p = 0.15$) maps.

description: We study within the Faddeev framework the \vec{3He} (\vec{e},e' p)d as well as the \vec{3He} (\vec{e},e' p)pn and \vec{3He} (\vec{e},e' n)pp reactions in order to extract information on the proton and neutron polarization in polarized 3He. We achieve clear analytical insight for simplified dynamical assumptions and define conditions for experimental access to important 3He properties. In addition we point to the possibility to measure the electromagnetic proton form factors in the process \vec{3He} (\vec{e},e' p)d which would test the dynamical picture and put limits on medium corrections of the form factors.

description: Recent events due to the Coronavirus (Covid-19) pandemic have led to increased interest in personal protective equipment (PPE). Antiviral activity in PPEs has become desirable in the wake of the Covid-19 pandemic due in 2020 due to the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus. This work aims to characterise morphological and surface properties of fabrics enhanced with known antiviral agents for PPE application. The Textilise™ process, a modified textile padding technique, was utilised to incorporate antiviral agents into the fabric matrix. Silver (Ag), silver liposome (Ag LP) and silane coupled quaternary ammonium cation (QS) as a selection of metal, metal-organic and inorganic-organic based agents respectively. Superwhite (SW) and cream coloured cotton/polyester fabric blends selected as the substrate were coated via the pad-dry-cure method. Bromophenol blue (BPB) test followed by UV-Vis was found to be a useful qualitative indicator for chemical concentration on the fabric surface. A linear relationship between increasing antiviral NP content and decreasing BPB absorbance was found. Detection of QS, Ag and Ag LP modified fabrics was achievable at concentrations as low as 200 µg/g, 17.53 µg/g and 9.22 µg/g respectively for SW fabrics. The NP content was determined by acid assisted microwave digestion followed by induced coupled plasma spectroscopy. Affinity of agents to fabrics was determined by the Langmuir and Freundlich adsorption isotherms. Both isotherms suggested improved adsorption for cream fabrics, but the heterogeneous assumptions of the Freundlich isotherms are more appropriate for agent/fabrics systems. Electron microscopy revealed Ag LP and QS presence on samples. Ag LP particles formed a uniform distribution on fibre. QS agglomerates were present on textiles surfaces and in between individual fibres largely attributed to overtreatment. X-ray photoelectron spectroscopy confirmed the elemental composition of Ag 3d, Si 2p and N 1s bands on modified fabrics. Electrokinetic analysis successfully alterations in the surface zeta potential due to the varying degrees of agent finishing. These results are advantageous and can be considered safety and quality by design systems.

Essay: Sunday shopping - The case of three surveys
Creators: name: Bethlehem, Jelke
Publisher: name: European Survey Research Association

Subjects: Probability sampling; non-probability sampling; self-selection; web survey

description: There is a growing discussion about the use of non-probability sampling in survey research. Probability sampling is the preferred method of sample selection, but practical problems like reduced data collection budgets, increasing nonresponse rates, and lack of adequate sampling frames force researchers to use different sampling methods. Particularly, online surveys based on self-selection of respondents have become very popular. Some say that use of such alternative sampling methods is not without risks as often proper inference from sample to population is not possible. Others say that non-probability sampling  can produce satisfactory estimates provided effective correction techniques are applied. To obtain more insight in various sample selection methods, it would be nice to be able to compare them in practical situations. This paper describes a case in which three different surveys were carried out on the same topic, at the same time, and with the same questionnaire, but with different sample selection methods: an online panel based on probability sampling, an online survey based on self-selection, and a face-to-face survey in shopping centers. The results of these three polls differ substantially. This is a warning to be careful when choosing a sample selection method.

description: Jacutingate, a recently discovered Brazilian naturally occurring mineral, has shown to be the first experimental realization of the Kane-Mele topological model. In this letter we have unveiled a class of materials $M_2NX_3$ ($M$=Ni, Pt, Pd; $N$=Zn, Cd, Hg; and $X$=S, Se, Te), sharing jacutingaite's key features, i.e., high stability, and topological phase. By employing first-principles calculations we extensively characterize the energetic stability of this class while showing a common occurrence of the Kane-Mele topological phase. Here we found Pt-based materials surpassing jacutingaite's impressive topological gap and lower exfoliation barrier while retaining its stability.
An efficient and effective computation of 2-dimensional depth contours

description: Depth contour computation is a useful aid to outlier detection. For two-dimensional datasets, Rousseeuw and Ruts' ISODEPTH has been the state-of-the-art algorithm. Further contributions involve improving its efficiency and effectiveness, and resolving the issue of higher-dimensional datasets. This thesis details our research in these two areas. It presents a Fast Depth Contour Algorithm - FDC, which permits the selection of useful data points for processing and the removal of data point positioning limitations. Different selection methods result in the creation of FDC-basic and FDC-enhanced; and for buffer-space-compatibility, three further variants (FDC-M1, FDC-M2, and FDC-M3) of FDC-basic have been developed. FDC-basic capitalizes on the normal location of outiers and the relevancy of the vertices of convex hulls in depth contour computation. By computing with only the useful data points, it proves to run 150 times faster than ISODEPTH when computing the first 21 depth contours of a 6500-point dataset. FDCenhanced takes only a quarter of the time required by FDC-basic to compute the first 151 depth contours of a 100,000-point dataset because it maintains a constantly adjusted sorted list of the useful data points to reduce redundant computation. FDC-M1 keeps dividing the dataset into subsets and discarding the useless data points until the union of the subsets fits the buffer size. FDC-M2 further uses a periodically adjusted inner convex hull to filter useless data points. FDC-M3 saves buffer space by starting the computation with a minimum dataset, which is enlarged with additional useful data points for each succeeding computation. To tackle datasets of higher dimensions, we have pioneered a promising algorithm in 3-dimensional computation, FDC-3D, which can be improved with the use of sorted lists. Algorithm Fast Depth Contour not only provides an efficient and effective tool for immediate use, but also suggests a direction for future studies.

description: A wide range of neuropsychological disorders is caused by serotonin 5-HT2A receptor (5-HT2AR) malfunction. Therefore, this receptor had been frequently used as target in CNS drug research. To design novel potent 5-HT2AR antagonists, we have combined ligand-based and target-based approaches. This study was performed on wide range of structurally diverse antagonists that were divided into three different clusters: clozapine, ziprasidone, and ChEMBL240876 derivatives. By performing the 50ns long molecular dynamic simulations with each cluster representative in complex with 5-HT2A receptor, we have obtained virtually bioactive conformations of the ligands and three different antagonist-bound, inactive, conformations of the 5-HT2AR. These three 5-HT2AR conformations were further used for docking studies and generation of the bioactive conformations of the data set ligands in each cluster. Subsequently, selected conformers were used for 3D-Quantitative Structure Activity Relationship (3D-QSAR) modelling and pharmacophore analysis. The reliability and predictive power of the created model was assessed using an external test set compounds and showed reasonable external predictability. Statistically significant variables were used to define the most important structural features required for 5-HT2A antagonistic activity. Conclusions obtained from performed ligand-based (3D-QSAR) and target-based (molecular docking and molecular dynamics) methods were compiled and used as guidelines for rational drug design of novel 5-HT2AR antagonists.
Continuum approach to real time dynamics of 1+1D gauge field theory: out of horizon correlations of the Schwinger model

description: We develop a truncated Hamiltonian method to study nonequilibrium real time dynamics in the Schwinger model - the quantum electrodynamics in D=1+1. This is a purely continuum method that captures reliably the invariance under local and global gauge transformations and does not require a discretisation of space-time. We use it to study a phenomenon that is expected not to be tractable using lattice methods: we show that the 1+1D quantum electrodynamics admits the dynamical horizon violation effect which was recently discovered in the case of the sine-Gordon model. Following a quench of the model, oscillatory long-range correlations develop, manifestly violating the horizon bound. We find that the oscillation frequencies of the out-of-horizon correlations correspond to twice the masses of the mesons of the model suggesting that the effect is mediated through correlated meson pairs. We also report on the cluster violation in the massive version of the model, previously known in the massless Schwinger model. The results presented here reveal a novel nonequilibrium phenomenon in 1+1D quantum electrodynamics and make a first step towards establishing that the horizon violation effect is present in gauge field theory.
