description: Layered van der Waals materials offer a unique platform for creating atomic-void channels with sub-nanometer dimensions. Coupling light into these channels may further advance sensing, quantum information, and single molecule chemistries. Here we examine limits of light guiding in atomic-void channels and show that van der Waals materials exhibiting strong resonances - excitonic and polaritonic - are ideally suited for deeply subwavelength light guiding. We demonstrate that excitonic transition metal dichalcogenides can squeeze > 70% of optical power in just < λ/100 thick channel in the visible and near-infrared. We also show that polariton resonances of hexagonal boron nitride allow deeply subwavelength (< λ/500) guiding in the mid-infrared. We further reveal effects of natural material anisotropy and discuss the influence of losses. Our analysis shows van der Waals channel waveguides while offering extreme optical confinement exhibit significantly lower loss compared to plasmonic counterparts. Such atomic void waveguides pave the way to low loss and deeply subwavelength optics.

description: Multidrug-resistant bacteria are among the most important current threats to public health. Typically, they are associated with nosocomial infections. However, some have become prevalent causes of community-acquired infections, such as Neisseria gonorrhoeae, Shigella, Salmonella, and Streptococcus pneumoniae. The community spread of multidrug-resistant bacteria is also a crucial development. An important global threat on the horizon is represented by production of carbapenemases by community-acquired hypervirulent Klebsiella pneumoniae. Such strains have already been found in Asia, Europe, and North America. Prevention of further community spread of multidrug-resistant bacteria is of the utmost importance, and will require a multidisciplinary approach involving all stakeholders.

description: There is growing evidence that when magnetic reconnection occurs in high Lundquist number plasmas such as in the Solar Corona or the Earth's Magnetosphere it does so within a fragmented, rather than a smooth current layer. Within the extent of these fragmented current regions the associated magnetic flux transfer and energy release occurs simultaneously in many different places. This investigation focusses on how best to quantify the rate at which reconnection occurs in such layers. An analytical theory is developed which describes the manner in which new connections form within fragmented current layers in the absence of magnetic nulls. It is shown that the collective rate at which new connections form can be characterized by two measures; a total rate which measures the true rate at which new connections are formed and a net rate which measures the net change of connection associated with the largest value of the integral of $E_{\|}$ through all of the non-ideal regions. Two simple analytical models are presented which demonstrate how each should be applied and what they quantify.

description: One of the major problems for doped silicon used for solar cells is the effect called light induced degradation, since it can reduce the absolute effciency by up to 2 %. Despite being known for over four decades the actual defect structure neither for boron, indium nor gallium-doped silicon are known with certainty. Different defect models have been introduced like boron-oxygen or the ASiSii-defect. Further it was shown that a photoluminescence feature called P-line shows correlation to applied illumination and annealing. Therefore in this work this correlation is investigated in more detail. Furthermore the ASiSii-defect model is substantiated, by supplying an energy barrier calculated from measurements.
description: Eines der größten Probleme für dotiertes Silizium, zur Verwendung in Solarzellen, ist der sogenannte Effekt der lichtinduzierten Degradation. Diese Degradation ist von besonderer Bedeutung, da sie die absolute Effizienz einer Solarzelle um bis zu 2% verringern kann. Obwohl dieser Umstand bereits seit vier Jahrzehnten bekannt ist, gibt es weiterhin einen wissenschaftlichen Diskurs über die tatsächliche Defektstruktur für Bor, Indium und Gallium dotiertes Silizium. Verschiedene Modelle wurden vorgeschlagen, wie der Bor-Sauerstoff Defekt oder der ASiSii-Defekt. Weiterhin wurde gezeigt, dass eine Photolumineszenzlinie, die sogenannte P-Linie, eine Korrelation zu angewandter Beleuchtung oder Temperierung zeigt. Diese Arbeit widmet sich daher ausführlicher dieser Korrelation. Zusätzlich kann das ASiSii-Defektmodell weiter präzisiert werden, indem eine Energiebarriere, aus den Messungen berechnet, auf das Modell angewendet werden kann.

description: Malta has become a diverse country and educators are facing challenges in adapting their pedagogies to their current students. Given that parents were opting their children out of catholic religion lessons, the Ethics curriculum was introduced in the primary and secondary classroom. However, no direction was given with regards to moral education in the kindergarten classroom with children aged 3-5. This study seeks to explore how kindergarten educators are transmitting morality in their classroom and what impacts these transmission practices. This descriptive research used cluster sampling. Seven kindergarten educators whose ages range between 30 -60 participated in two two-hour focus groups representing the diverse demographic and needs of the students in the colleges of Malta and Gozo. Given the flexibility and organisational approach, thematic analysis was used to code the focus groups. The major findings are that teachers’ beliefs followed by school climate are salient factors in the impact on moral educational strategies. Moral education was mostly imparted through the teaching of society’s moral norms. This study suggests that future research investigates the impacts of teachers’ beliefs on the children’s identity and studying how children’s religious identity impacts their prosocial behaviours and relationships in the classroom. This will shed light on policies for religious and moral education in the kindergarten state schools.

description: Precision sensing, and in particular high precision magnetometry, is a central goal of research into quantum technologies. For magnetometers, often trade-offs exist between sensitivity, spatial resolution, and frequency range. The precision, and thus the sensitivity of magnetometry, scales as $1/\sqrt {T_2}$ with the phase coherence time, $T_2$, of the sensing system playing the role of a key determinant. Adapting a dynamical decoupling scheme that allows for extending $T_2$ by orders of magnitude and merging it with a magnetic sensing protocol, we achieve a measurement sensitivity even for high frequency fields close to the standard quantum limit. Using a single atomic ion as a sensor, we experimentally attain a sensitivity of $4.6$ pT $/\sqrt{Hz}$ for an alternating-current magnetic field near 14 MHz. Based on the principle demonstrated here, this unprecedented sensitivity combined with spatial resolution in the nanometer range and tunability from direct-current to the gigahertz range could be used for magnetic imaging in as of yet inaccessible parameter regimes.

description: Treatment options for multidrug-resistant (MDR) gram-negative infection are growing. However, postregistration, pragmatic, and clinician-led clinical trials in this field are few, recruit small sample sizes, and experience deficiencies in design and operations. MDR gram-negative therapeutic trials are often inefficient, only evaluating a single antibiotic or strategy at a time. Novel clinical trial designs offer potential solutions by attempting to obtain clinically meaningful conclusions at the end or during a trial, for many treatment strategies, simultaneously. An integrated, consensus approach to MDR gram-negative infection trial design is crucial.

description: The United States of America is a super state in the world, which supports other countries to protect human rights, build international relations, avoid gender discrimination and achieve economic development. Surprisingly, a country where more than 50 percent of population is woman has never elected a female president. This issue constantly draws attention because from the first presidential elections in 1789 to present, Americans have being distrusted to woman candidate. The first reason of women’s underrepresentation in American politics was historical inequality between men and women (the Anglo-Indian gender frontier). The history of Native Americans demonstrates a huge division between the roles of males and females. Secondly, after the foundation of the US Constitution, legal gender discrimination took place. For example, founder women were excluded from the list of Founding Fathers. Thirdly, men are more interested in politics than women and this is fundamental reason of women’s underrepresentation in politics. The level of political ambition is important for running for office - men tend to have it women do not. The fourth reason is that Americans still are not ready to elect a woman for office. Several poll experiments have shown that citizens of the United States would vote for a qualified woman but they do the opposite in elections. The fifth reason is that beside official constitutional requirements for president, many other unofficial requirements exist too (prior political experience, name recognition, party support, adequate funding and etc.), which complicates running for office especially for a woman candidate.The aim of this paper is to introduce fundamental reasons, why the United States has not elected a female president during 231 years, when women can perform as well as men in running for office. The paper includes five parts: introduction, observations, findings, conclusion and bibliography. In findings, with qualitative and quantitative research methods, primary and secondary documents are analyzed and several tendencies are identified: exclusion of women from the list of Founding Fathers, the use of masculine pronouns ‘he’ and ‘his’ in the US Constitution, extension of the deadline of ERA’s ratification and pregnancy discrimination, which still remains impeding factor for American women.

description: Let $X$ be an algebraic variety such that the group $\text{Aut}(X)$ acts on $X$ transitively. We define the transitivity degree of $X$ as a maximal number $m$ such that the action of $\text{Aut}(X)$ on $X$ is $m$-transitive. If the action of $\text{Aut}(X)$ is $m$-transitive for all $m$, the transitivity degree is infinite. We compute the transitivity degree for all quasi-affine toric varieties and for many homogeneous spaces of algebraic groups. Also we discuss a conjecture and open questions related to this invariant.

description: The United States of America is the leader democracy in the world, which supports other countries to protect human rights, build international relations, avoid gender discrimination and achieve high level of development. Surprisingly, a country where more than 50 percent of population is woman (Worldometers. 2018) has never elected a female president. This topic constantly draws attention, because from the declaring of the independence to present, Americans always distrusted woman candidate. The first reason is historical inequality between men and women. American history has kept some facts when woman was considered as an extension of her husband and did not need her own vote. Secondly, the level of political ambition between males and females is different. Men and women do not have an equal interest in politics. This is fundamental reason of women’s under-representation in politics. The third reason is strange behavior of Americans during presidential elections. The fourth, beside official, constitutional requirements, many other unofficial requirements exist and there the prospect becomes trickier for a woman candidate. In contrast to the past, today women are more involved in presidential and other political campaigns, but despite this, in most of cases citizens select males anyway. Both parties, Democrats and Republicans claim that their party would get the first woman into the White House.The aim of this paper is to introduce fundamental reasons, why has the USA never elected a female president, when women can perform as well as men in running for office. Primary and secondary documents are analyzed with qualitative research. There are also used official statistics of international organizations (CAWP, IPU). Major research is based on the analysis of the US Constitution.

description: Human erythroid leukemia (HEL) is an unusual heterogeneous entity conveying 3-5% of all acute myeloid leukemia (AML) and 20-30% of secondary leukemias. The occurrence of erythroleukemia rises in people older than 50 years. Erythroleukemia is a tumorous proliferation of erythroid and myeloid precursors of bone marrow hematopoietic stem cells. Phloretin is a dihydrochalcones and combined with Heat Shock 70kDa Protein HSP70 (PDB ID: 5AQY) that has shown a promising activity against HEL. Phloretin had a strong ability to block HEL cells growth binding with HSP70 protein. The main mechanism of action is increase the anti-tumor activity of HPS70 with phloretin combination on HEL K-562 cells. In this studies, we evaluated the latent pharmacological activity and diverse modified drugs compared to the parent drug phloretin combined with HSP70 for the treatment of HEL cancer. Molecular docking calculation showed that HSP70 (5AQY) is the main protein to which phloretin binds with value of-8.4 kcal/mol. Two modified drugs revealed increased binding affinity toward 5AQY. Both modified derivatives were prepared changing the C17 position by with the addition group-C6H5 and-C10H7 significantly combined with HSP70 protein with binding affinity-9.4 kcal/mol and-10.9 kcal/mol respectively. Furthermore, designed drugs revealed better/enhanced pharmacokinetic properties. Theoretical B3LYP/6-31G (d, p) density functional theory (DFT) has been hired to sanctify their physicochemical properties. Frontier orbital features (HOMO-LUMO gap, degree of viscosity) of these altered compounds are also observed in the subsequent investigation. The ADMET investigation expected that they are not capable of crossing the Blood-Brain Barrier (BBB) as well as lipophilicity, oral bioavailability and plasma protein binding were greatly increased than that of standard drug. The methodological statement demonstrates that phloretin analogues can be the effective drug for HSP70. In future, we will suggest to synthesize the investigational method for D-C10H7 as the prime derivatives of phloretin for the therapy of Human erythroid leukemia (HEL).

description: This docuent contains the National Strategy for Conservation and Sustainable Use of Plant Genetic Resources for Food and Agriculture in Zambia and was developed in a participatory approach involving key national stakeholders with initial support through the TCP/SFS/3402 Project, “Support for the development of national strategies for plant genetic resources for food and agriculture” complemented by support from the project PR-231-Malawi, funded in the 4th cycle of the Benefit Sharing Fund (BSF) of the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) of the Food and Agriculture Organization (FAO).

This strategy aims to promote and ensure the rationalized conservation and management of plant genetic resources for food and agriculture in Zambia. It presents a succinct review of the status of plant genetic resources management in the country, identifies the emerging challenges and formulates a National Plan of Action for the coming 5 years with a set of key actions covering conservation and utilization, enabling legal environment, strengthening capacities for PGRFA research and development and of local communities, technical staff and decision makers in a comprehensive integrated approach.

It also serves as a tool and strategy for policy guidance in the conservation and sustainable use of PGRFA and calls for aligning the activities relevant to the International Treaty of Plant Genetic Resources for Food and Agriculture with other long term national development plans relevant to , for example, the Convention on Biological Diversity.

description: Density functional plus dynamical mean field calculations are used to show that in transition metal oxides, rotational and tilting (GdFeO$_3$-type) distortions of the ideal cubic perovskite structure produce a multiplicity of low-energy optical transitions which affect the conductivity down to frequencies of the order of $1$ or $2$~mV (terahertz regime), mimicking non-Fermi-liquid effects even in systems with a strictly Fermi-liquid self-energy. For CaRuO$_3$, a material whose measured electromagnetic response in the terahertz frequency regime has been interpreted as evidence for non-Fermi-liquid physics, the combination of these band structure effects and a renormalized Fermi-liquid self-energy accounts for the low frequency optical response which had previously been regarded as a signature of exotic physics. Signatures of deviations from Fermi-liquid behavior at higher frequencies ($\sim 100$~meV) are discussed.

description: We describe the determination of the heavy quarks structure functions $F_{2,L}^{\mathcal{Q}\bar{\mathcal{Q}}}$ with help of the scaling properties. We observe that the structure functions for inclusive charm and bottom production exhibits geometric scaling at low $x$. The geometrical scaling means that the heavy quark structure function is a function of only one dimensionless variable $τ{\equiv}Q^{2}/Q^{2}_{sat}(x)$ including quark mass. These results are valid for any value of $δ$, being $x^{-δ}$ the behavior of the parton densities at low $x$. The determination of the heavy quark structure function is presented as a parameterization of the proton structure function $F_{2}(x,Q^{2})$ and its derivative. Analytical expressions for $F_{2,L}^{\mathcal{Q}\bar{\mathcal{Q}}}$ in terms of the effective parameters of the parameterization of $F_{2}(x,Q^{2})$ ,with respect to the BDH and ASW models, are presented. To study the heavy quark production processes, we use the collinear results in DAS approach. Numerical calculations and comparison with HERA data demonstrate that the suggested method provides reliable $F_{2}^{\mathcal{Q}\bar{\mathcal{Q}}}$, $R^{c\bar{c}}$ and $σ^{\mathcal{Q}\bar{\mathcal{Q}}}$ at low $x$ in a wide range of the low absolute four-momentum transfers squared ($4~\mathrm{GeV}^{2}

description: We report GaAs/AlGaAs nanowires in the one-dimensional (1D) quantum limit. The ultrathin wurtzite GaAs cores between 20-40\,nm induce large confinement energies of several tens of meV, allowing us to experimentally resolve up to four well separated subband excitations in microphotoluminescence spectroscopy. Our detailed experimental and theoretical polarization-resolved study reveals a strong diameter-dependent anisotropy of these transitions: We demonstrate that the polarization of the detected photoluminescence is governed by the symmetry of the wurtzite 1D quantum wire subbands on the one hand, but also by the dielectric mismatch of the wires with the surrounding material on the other hand. The latter effect leads to a strong attenuation of perpendicularly polarized light in thin dielectric wires, making the thickness of the AlGaAs shell an important factor in the observed polarization behavior. Including the dielectric mismatch to our k.p-based simulated polarization-resolved spectra of purely wurtzite GaAs quantum wires, we find an excellent agreement between experiment and theory.

description: Poverty is one of the most important problems in the whole world. Definitions of poverty are debatable, but there is common agreement about its degrees. Poverty is profiled by shacks, homelessness, unemployment, poor infrastructure and lack of access to basic services. Half of the world population, more than 3 billion people, is poor (United Nations, 2014).Poor people are in democratic countries too and they have the same problems as people, who live in less democratic or non-democratic developing countries. If we see the statistics, it will not be difficult to understand, how hard this problem is. How does politics explain poverty in the conditions of rich democracy? – This is the main question of our scientific work, in which we used quantitative and qualitative researches in order to describe the issue perfectly. Major research includes cases of countries, which are democratic but still on the poverty level. Also we have made a poll experiment in Georgia.

description: Super-Efimov states are a new kind of universal three-body bound states predicted for three identical fermions with $p$-wave resonant interactions in two dimensions by a recent field-theoretic calculation [Phys.~Rev.~Lett.~\textbf{110}, 235301 (2013)]. The binding energies of these states obey a dramatic double exponential scaling $E_n=E_*\exp(-2 e^{πn/s_0+θ})$ with universal scaling $s_0=4/3$ and three-body parameters $E_*$ and $θ$. We use the hyperspherical formalism and show that the super-Efimov states originate from an emergent effective potential $-1/4ρ^2-(s_0^2+1/4)/ρ^2\ln^2\left(ρ\right)$ at large hyperradius $ρ$. Moreover, for pairwise interparticle potentials with van der Waals tails, our numerical calculation indicates that the three-body parameters $E_*$ and $θ$ are also universal and the ground super-Efimov state shall cross the threshold when the $2$D $p$-wave scattering area is about $-42.0\, l_\text{vdW}^2$ with $l_\text{vdW}$ the van der Waals length.

description: Background. Predicting mortality risk in patients is important in research settings. The Pitt bacteremia score (PBS) is commonly used as a predictor of early mortality risk in patients with bloodstream infections (BSIs). We determined whether the PBS predicts 14-day inpatient mortality in nonbacteremia carbapenem-resistant Enterobacteriaceae (CRE) infections. Methods. Patients were selected from the Consortium on Resistance Against Carbapenems in Klebsiella and Other Enterobacteriaceae, a prospective, multicenter, observational study. We estimated risk ratios to analyze the predictive ability of the PBS overall and each of its components individually. We analyzed each component of the PBS in the prediction of mortality, assessed the appropriate cutoff value for the dichotomized score, and compared the predictive ability of the qPitt score to that of the PBS. Results. In a cohort of 475 patients with CRE infections, a PBS 4 was associated with mortality in patients with nonbacteremia infections (risk ratio [RR], 21.9 95% confidence interval [CI], 7.0, 68.8) and with BSIs (RR, 6.0 95% CI, 2.5, 14.4). In multivariable analysis, the hypotension, mechanical ventilation, mental status, and cardiac arrest parameters of the PBS were independent risk factors for 14-day all-cause inpatient mortality. The temperature parameter as originally calculated for the PBS was not independently associated with mortality. However, a temperature < 36.0° C vs 36° C was independently associated with mortality. A qPitt score 2 had similar discrimination as a PBS 4 in nonbacteremia infections. Conclusions. Here, we validated that the PBS and qPitt score can be used as reliable predictors of mortality in nonbacteremia CRE infections.

description: Aspect-level sentiment analysis aims to determine the sentiment polarity towards a specific target in a sentence. The main challenge of this task is to effectively model the relation between targets and sentiments so as to filter out noisy opinion words from irrelevant targets. Most recent efforts capture relations through target-sentiment pairs or opinion spans from a word-level or phrase-level perspective. Based on the observation that targets and sentiments essentially establish relations following the grammatical hierarchy of phrase-clause-sentence structure, it is hopeful to exploit comprehensive syntactic information for better guiding the learning process. Therefore, we introduce the concept of Scope, which outlines a structural text region related to a specific target. To jointly learn structural Scope and predict the sentiment polarity, we propose a hybrid graph convolutional network (HGCN) to synthesize information from constituency tree and dependency tree, exploring the potential of linking two syntax parsing methods to enrich the representation. Experimental results on four public datasets illustrate that our HGCN model outperforms current state-of-the-art baselines.

description: By Maxwell equal area law we study the phase transition in higher dimensional Anti-de Sitter (AdS) Reissner-Nordström (RN) black hole and Kerr black hole in this paper. The coexisting region of the two phases involved in the phase transition is found and the coexisting curves are shown in $P-T$ figures. We also analytically investigate the parameters which affect the coexisting curves. To better compare with ordinary thermodynamic systems, the Clapeyon equation is derived for higher dimensional AdS black holes. This paper can help to deepen the understanding of the phase transition and phase structure of AdS black holes.

description: Poverty is one of the most important problems in the whole world. Definitions of poverty are debatable, but there is common agreement about its degrees. Poverty is profiled by shacks, homelessness, unemployment, poor infrastructure and lack of access to basic services. Half of the world population, more than 3 billion people, is poor (United Nations, 2014).Poor people are in democratic countries too and they have the same problems as people, who live in less democratic or non-democratic developing countries. If we see the statistics, it will not be difficult to understand, how hard this problem is. How does politics explain poverty in the conditions of rich democracy? – This is the main question of our scientific work, in which we used quantitative and qualitative researches in order to describe the issue perfectly. Major research includes cases of countries, which are democratic but still on the poverty level. Also we have made a poll experiment in Georgia.

description: Background: Carbapenem-resistant Enterobacterales (CRE) are a global threat. We aimed to describe the clinical and molecular characteristics of Centers for Disease Control and Prevention (CDC)-defined CRE in the USA. Methods: CRACKLE-2 is a prospective, multicentre, cohort study. Patients hospitalised in 49 US hospitals, with clinical cultures positive for CDC-defined CRE between April 30, 2016, and Aug 31, 2017, were included. There was no age exclusion. The primary outcome was desirability of outcome ranking (DOOR) at 30 days after index culture. Clinical data and bacteria were collected, and whole genome sequencing was done. This trial is registered with ClinicalTrials.gov, number NCT03646227. Findings: 1040 patients with unique isolates were included, 449 (43%) with infection and 591 (57%) with colonisation. The CDC-defined CRE admission rate was 57 per 100 000 admissions (95% CI 45–71). Three subsets of CDC-defined CRE were identified: carbapenemase-producing Enterobacterales (618 [59%] of 1040), non-carbapenemase-producing Enterobacterales (194 [19%]), and unconfirmed CRE (228 [22%]; initially reported as CRE, but susceptible to carbapenems in two central laboratories). Klebsiella pneumoniae carbapenemase-producing clonal group 258 K pneumoniae was the most common carbapenemase-producing Enterobacterales. In 449 patients with CDC-defined CRE infections, DOOR outcomes were not significantly different in patients with carbapenemase-producing Enterobacterales, non-carbapenemase-producing Enterobacterales, and unconfirmed CRE. At 30 days 107 (24%, 95% CI 20–28) of these patients had died. Interpretation: Among patients with CDC-defined CRE, similar outcomes were observed among three subgroups, including the novel unconfirmed CRE group. CDC-defined CRE represent diverse bacteria, whose spread might not respond to interventions directed to carbapenemase-producing Enterobacterales. Funding: National Institutes of Health.
Local, nonlocal quantumness and information theoretic measures

description: It has been suggested that there may exist quantum correlations that go beyond entanglement. The existence of such correlations can be revealed by quantum discord, but not by the conventional measure of entanglement. We argue that a state displays quantumness that can be of local and nonlocal origin. The physical quantity such as the quantum discord probes not only the nonlocal quantumness but also the local quantumness, such as the "local superposition". This can be a reason why such measures are non-zero when there is no entanglement. We consider a generalized version of the Werner state to demonstrate the interplay of local quantumness, nonlocal quantumness, and classical mixedness of a state.

description: Recently A.Galajinsky has suggested the N=1 supersymmetric extension of Euler top and made a few interesting observations on its properties [arXiv:2111.06083 [hep-th]]. In this paper we use the formulation of the Euler top as a system on complex projective plane, playing the role of phase space, i.e. as a one-dimensional mechanical system. Then we suggest the supersymmetrization scheme of the generic one-dimensional systems with positive Hamiltonian which yields a priori integrable family of N=2k supersymmetric Hamiltonians parameterized by N/2 arbitrary real functions.

description: In most recent years, prostate cancer (PC) has been a common type of cancer that is confined to the prostate gland. Alpha-Pinene (AP) is one of the major complications for PC therapeutics as a hopeful chemotherapeutic drug for admin in hepatocellular carcinoma. Zhao et al. experienced the inhibitory potential of alpha-pinene on human prostate cancer in a mouse xenograft model. In this study, we have reported the design of a number of copper and other metal-dependent donepezil derivaties, employing density function theory (DFT). The designed compounds are optimized at the B3LYP/SDD level of theory. The subsequent analysis also investigates the dipole moment, electronic energy, enthalpies, Gibbs free energies, and HOMO-LUMO gaps of these adapted compounds. The molecules were at that time subjected to molecular docking analysis with alpha-pinene to revise the molecular connections broadly. For acquiring the best binding energy, it was used in the Autodock Vina Docking protocol. Ensemble-dependent docking and molecular dynamics (MD) simulations of the most candidates were also performed, such as Benzene (B), Napthalene (N), and-OCF3,-OCCl3 groups. Docking and MD simulation reveal that modified drugs are more powerful than unmodified donepenzil, where 1h72, 4yc6, 6gu7, 3op3, and 6gu6 residues take part in some important roles in drug-receptor connections. The AP-B derivated drug showed a requirement energy of-10.0 kcal/mol with protein 1h72 in the receptor M2 family compared to the key drug, which showed a requirement energy of-6.7 kcal/mol with a similar protein. All the modified drugs showed considerable Homo-Lumo, hermodynamic properties, and pharmacokinetics properties. These data strongly suggest that alpha-pinene inhibits prostate cancer development in a xenograft model and may be a helpful therapeutic mediator for prostate cancer action.

description: After the World War II, when nuclear weapons were bilaterally created, economic statecraft became actual way to fight against regimes, which were breaking international order and stability. The aim of economic statecraft is to coerce target state to change its political behavior. Countries use both, positive (incentive) and negative economic sanctions to reach their political goals, however the result is debatable. There is a question when a country imposes sanctions on the target state: will these sanctions work or not? - authors, such as Daniel Drezener, Robert Pape and Gary Claude Hufbauer have answered to this question, but their positions are different and there is not any bright position to believe in the effectiveness of economic sanctions.The aim of the research ‘Do Economic Sanctions work?’ is to define conditions and reasons that have an effect on economic diplomacy. The major research includes case study – the USA sanctions against Venezuela and explains why the coercion was successful or unsuccessful in concrete situations. The research shows that political regime in target country determines the effectiveness of economic sanctions. More autocracy means more difficulties for sender but in the conditions of democracy – vice versa.

description: We discuss dynamics of periodically-driven open quantum systems. The time evolution of the quantum state is described by the quantum master equation and the form of the dissipator is chosen so that the instantaneous stationary state is given by the Gibbs distribution. We find that the correlation between the population part and the coherence part of the density operator is induced by an adiabatic gauge potential. Although the introduction of the counterdiabatic term eliminates the correlation, additional correlations prevent a convergence to the Gibbs distribution. We study the performance of the control by the counterdiabatic term. The system has three different scales and the performance strongly depends on the relations among their magnitudes.
