description: We discuss the possibility of using circularly polarized luminescence (CPL) as a tool to probe individual triplet spin sublevels that are populated nonadiabatically following photoexcitation. This study is motivated by a mechanism pro- posed for chirality-induced spin selectivity in which coupled electronic-nuclear dynamics may lead to a non-statistical population of the three triplet sublevels in chiral systems. We find that low-temperature CPL should aid in quantifying the exact spin state/s populated through coupled electronic-nuclear motion in chiral molecules.

description: Thiophene is a core structure in many marketed drugs, such as Duloxetine, Tiotropium, Raloxifene, Dorzolamide, Tioconazole, Citizolam, Sertaconazole Nitrate and Benocyclidine. Thiophene derivatives are reported to have several types of pharmacological and biological activities. The synthesis of new thiophene derivatives is important to pharmaceutical research, because of their diverse pharmacological activities. The reaction of ethyl 3-oxobutanoate with carbon disulfide and chloroacetone in the presence of K2CO3 affords the unexpected thiophene derivative 7. Furthermore, refluxing compound 7 with dimethylformamide-dimethylacetal (DMF-DMA) in DMF affords the enaminone derivative 8. The structures of these newly synthesized compounds were confirmed by means of various spectroscopic techniques, such as IR, MS, and NMR, as well as by X-ray diffraction. In addition, B3LYP/6-311G(d, p) basis sets were employed to optimize the molecular geometry of the two thiophene derivatives. Furthermore, natural atomic charges and frontier molecular orbital analyses were performed. Hirshfeld analysis of the molecular packing showed that H—H, O—H, C—H, and S—H are the most common intermolecular interactions in both compounds. Further analysis suggests that the O—H interactions are the most significant of these in compounds 7 and 8.

Atomosia

description: Atomosia Macquart
 Atomosia Macquart, 1838: 73 (1839: 189). Type species: incisuralis Macquart (Coquillett 1910: 512) = puella (Wiedemann).
 Remarks. This large primarily Neotropical genus includes about 50 species. Previously, six species were reported from the West Indies, 4 from Cuba (Bromley 1929) and 2 from Puerto Rico (Curran 1930). We report Atomosia from the Dominican Republic for the first time and 5 new species are described. The genus is distinguished by small robust bodies [5–12 mm], a strongly convergent vertex, and the antenna is without an apical style. The flagellum is longer than the scape and pedicel combined and has a dorsal excised notch at or beyond the middle that bears a minute spine-like bristle. The abdomen consists of 6 exposed segments with the sixth cup-shaped and concealing the terminalia. The dorsal surface of the tergites is coarsely punctate (Hull 1964). Species are very similar and often difficult to separate. Identification of species relies heavily on color patterns of the cuticle, tomentum, and vestiture. Male terminalia thus far have not been studied extensively and are usually not illustrated. Species perch on sunlit rocks, trees, branches, and leaves, and erect objects such as dead or live tree trunks, sides of buildings and fence supports. Perch selection is documented in only a few species.

description: We propose a method for predicting helical membrane protein structures by computer simulations. Our method consists of two parts. In the first part, amino-acid sequences of the transmembrane helix regions are obtained from one of existing WWW servers. In the second part, we perform a replica-exchange simulation of these transmembrane helices with some constraints and identify the predicted structure as the global-minimum-energy state. We have tested the method with the dimeric transmembrane domain of glycophorin A. The structure obtained from the prediction was in close agreement with the experimental data.

description: The evolution of non-hydrodynamic slow processes near the QCD critical point is explored with the novel Hydro+ framework, which extends the conventional hydrodynamic description by coupling it to additional explicitly evolving slow modes describing long wavelength fluctuations. Their slow relaxation is controlled by critical behavior of the correlation length and is independent from gradients of matter density and pressure that control the evolution of the hydrodynamic quantities. In this exploratory study we follow the evolution of the slow modes on top of a simplified QCD matter background, allowing us to clearly distinguish, and study both separately and in combination, the main effects controlling the dynamics of critical slow modes. In particular, we show how the evolution of the slow modes depend on their wave number, the expansion of and advection by the fluid background, and the behavior of the correlation length. Non-equilibrium contributions from the slow modes to bulk matter properties that affect the bulk dynamics (entropy, pressure, temperature and chemical potential) are discussed and found to be small.

description: This data article shows the nexus between absorptive capacity (X), innovation ambidexterity (Y1) and sustainable competitive advantage (Y2). There are three nexus points between the constructs, namely the direct nexuses of X to Y1, X to Y2 and the indirect nexus from X to Y2 through Y1. The raw data of 530 self-administrated questionnaires were obtained from 64 nonvocational private higher education institutions in the Bandung area of West Java, Indonesia. Data analyzing were conducted using SPPS and Smart PLS. The data are useful as the data can be reproduced, reused and reanalysed. This data article also opens up better research opportunities going forward through collaborationwith other researchers.

description: An efficient method has been developed for the synthesis of 3-[(2-amino-4-arylthiazolium-5-yl)(aryl)methyl]-2-oxo-2H-1-benzopyran-4-olates via a tandem reaction involving 4-hydroxycoumarin, benzaldehydes, thiourea, and 2-bromo-1-arylethan-1-ones, using p-toluenesulfonic acid as catalyst in glacial acetic acid under reflux. The identity of the parent product was confirmed by X-ray analyses while the other similar derivatives were identified by NMR. The good yields of the products, regioselectivity, and lack of metal promoters are the main advantages of this protocol. Highlights The reaction of 4-hydroxycoumarin, thiourea, benzaldehydes, and 2-bromo-1-arylethan-1-ones leads to the formation of functionalized 3-[(2-amino-4-arylthiazolium-5-yl)(aryl)methyl]-2-oxo-2H-1-benzopyran-4-olates in good yields.
How not to create a digital media scholarship platform: The history of the Sophie 2.0 project
Creators: name: Kirby, Jasmine
Publisher: name: Zenodo
Year: 2018

description: Since the mid-2000s digital platforms have emerged to take advantage of the capabilities of new technology to incorporate media content, tell nonlinear stories, and reinvent the book for the 21st century. Sophie 1.0, from the University of Southern California, the Institute for the Future of the Book (IFB), and computer scientists based in Europe, was an attempt to create a multimedia editing, reading, and publishing platform. Sophie 2.0 was an international collaboration between the University of Southern California and Astea Solutions in Bulgaria to rewrite Sophie 1.0 in the Java programming language. This research will explore how the Sophie 2.0 project was unable to become a viable and well-maintained open source product despite receiving over a million dollars in funding from the Mellon Foundation. Problems included the technological difficulty of creating an easy-to-use but completely customizable open source multimedia e-publishing platform, which was also compounded by competing visions over what this project was to be. Stakeholders did not demand a deliverable that actually worked. Funders seemed willing to overlook weaknesses in early releases for a more encompassing, if impractical, project. The computer scientists wanted to add the most features possible while, the IFB and USC Institute for Multimedia Literacy focused on creating a product based on the values of a future they hoped to create. Understanding what went wrong with Sophie 2.0 can help us understand how to create better digital media scholarship tools and to start much needed discussions about failure in the digital humanities.

description: In a large class of extra-dimensional models, a scalar degree of freedom known as the radion is long-lived, or even stable, on cosmological scales. In this paper we investigate the impact of radionactivity on the evolution of the universe. We demonstrate that whether the radion overcloses the universe, constitutes the dark matter, is the inflaton, the curvaton, or does not play any role in cosmology, depends crucially on the ratio between the energy densities stored in the radion and in the inflaton at the time of inflation. We discuss the general difficulties reconciling models with low compactification scale (i.e., TeV scale) with the simple picture of inflation.

description: The IEC 61850 standard is being largely used in the Smart Grid (SG) context mainly due to its ability to address communication, interoperability and migration issues. IEC 61850 currently aims at internal substation communication. Nevertheless, there is a demand to generalize its use for distributed SG systems like Home Energy Management Systems (HEMS) and Advanced Monitoring Infrastructure (AMI) Communication which potentially involves distributed substations or distributed SG components. IEC 61850- based systems require constrained timing requirements for communication and the common approach is to allocate static link bandwidth resources leading in some cases to over dimensioning. This paper presents the Substation Cognitive Communication Resource Management (IC2RM), that aims the management of bandwidth allocation for IEC messages using a cognitive approach for its provisioning and the SDN/OpenFlow for its deployment. By dynamically deploying bandwidth for IEC messages, IC2RM optimizes links between SG substations and systems and potentially reduces the operational costs (OPEX).

description: A central issue in complex networks is tolerance to random failures and intentional attacks. Current literature emphasizes the dichotomy between networks with a power-law node connectivity distribution, which are robust to random failures but fragile to targeted attacks, versus networks with an exponentially decaying connectivity distribution, which are less tolerant to failures but more resilient to attacks. We prove analytically that the optimal network configuration under a classic measure of robustness is altogether different from both of the above: in all cases, failure and/or attack, there are no more than three distinct node connectivities in the optimal network.

description: A facile carbon–sulfur bond formation was observed through the cellulose sulfonic acid (CSA) catalyzed dithioacetal protection of carbonyl compounds. In a preliminary study, the synthesis and characterization of functionalized bio-polymer, cellulose sulphonic acid (CSA) was achieved and its catalytic knack for dithioacetal protection was studied. It was discovered that CSA is an efficient, environmentally benign, recyclable catalyst for the synthesis of 1,1-dithioacetals or 1,1-dithioketals. A diverse range of aldehydes or ketones smoothly underwent the thioacetalization either with 1,3-dithiol or 1,2-dithiol. The 1,3-dithiol protection was found favored over 1,2-dithiol in terms of yields and reaction times. Acetonitrile at room temperature provides the best results among the solvents studied. The biodegradable nature of CSA, operationally simple protocol, good to excellent yields, shorter reaction times and need of very small amount of catalyst are the salient features of the present protocol.
Excavating narratives: An open database of an illustrated oeuvre from Myanmar (Burma)
Creators: name: Ker, Yin

Publisher: name: Zenodo
Year: 2018

description: What narratives might illustration as a medium and body of works carry, in addition to those divulged by individual illustrations? In Myanmar (Burma), as in many economically developing countries, illustration was the principal site of avant-garde artistic experimentation in a heavily censored society into which the art market had yet to penetrate. Yet, it has been thus far omitted in the prevailing art historical narrative. Through the illustrations of Myanmar's most prolific illustrator and acclaimed trailblazer of modern art, Bagyi Aung Soe (1923-1990), AungSoeillustrations.org (ASi) recounts the emergence of a novel artistic consciousness between 1948, the year the country gained political independence, and 1990 when Myanmar began to open up after almost three decades of isolation under a purportedly socialist regime. In addition, data visualisations of the illustrations created over four decades uncover narratives of a country, a people and an artist's aspirations and travails. This paper proposes to address the significance and process of uncovering and reinterpreting the (hi)story of a country's modern art through the digitisation, visual analysis, ontology creation, data curation, database design, and data visualisation of 6,000 illustrations and 60 texts sourced from private and public libraries in Paris and Yangon since 2000.

description: We study the single hadron inclusive production in the forward rapidity region in proton-nucleus collisions. We find the long-standing negative cross section at next-to-leading-order (NLO) is driven by the large negative threshold logarithmic contributions. We established a factorization theorem for resumming these logarithms with systematically improvable accuracy within the color glass condensate formalism. We demonstrate how the threshold leading logarithmic accuracy can be realized by a suitable scale choice in the NLO results. The NLO spectrums with the threshold logarithms resummed remain positive and impressive agreements with experimental data are observed.

Open infrastructure for research data stewardship with Fedora
Creators: name: Wilcox, David
Publisher: name: Zenodo
Year: 2018

description: Beyond the complexities faced by typical asset management or institutional repository systems, research data presents a number of complications, including complex hierarchies of related objects that must be modeled and displayed, a wider array of data formats that must be supported, and domain-specific metadata that is necessary to make data intelligible. Managing these complications often leads to software that is tailored to a particular domain, making it difficult to maintain or share. This presentation will provide an overview of how Fedora support supports research data management, including the roadmap for future development and integrations. Fedora is a flexible, extensible, open source repository platform for storing, managing, and preserving digital content, including research data. Fedora is used in a wide variety of institutions including libraries, museums, archives, and government organizations. Fedora supports research data management by providing key repository features such as support for millions of resources and files of any size, native linked data functionality, advanced data modeling, and preservation services. Fedora is also extremely well-suited to integrations with existing researcher workflows via a well-documented REpresentational State Transfer (REST) API and event-based messaging service.
On the Nature of the X-ray Emission from the Accreting Millisecond Pulsar SAX J1808.4-3658

description: The pulse profiles of the accreting X-ray millisecond pulsar SAX J1808.4-3658 at different energies are studied. The two main emission component, the black body and the Comptonized tail that are clearly identified in the time-averaged spectrum, show strong variability with the first component lagging the second one. The observed variability can be explained if the emission is produced by Comptonization in a hot slab (radiative shock) of Thomson optical depth ~0.3-1 at the neutron star surface. The emission patterns of the black body and the Comptonized radiation are different: a "knife"- and a "fan"-like, respectively. We construct a detailed model of the X-ray production accounting for the Doppler boosting, relativistic aberration and gravitational light bending in the Schwarzschild spacetime. We present also accurate analytical formulae for computations of the light curves from rapidly rotating neutron stars using formalism recently developed by Beloborodov (2002). Our model reproduces well the pulse profiles at different energies simultaneously, corresponding phase lags, as well as the time-averaged spectrum. We constrain the compact star mass to be bounded between 1.2 and 1.6 solar masses. By fitting the observed profiles, we determine the radius of the compact object to be R~11 km if M=1.6 M_sun, while for M=1.2 M_sun the best-fitting radius is ~6.5 km, indicating that the compact object in SAX J1808.4-3658 can be a strange star. We obtain a lower limit on the inclination of the system of 65 degrees.

description: Synthesis of functionalized 2-pyridone derivatives from thiazolo[3,2-a]pyridine-6-carbohydrazides or tetrahydroimidazo[1,2-a]pyridine-6-carbohydrazides was developed using acetic acid as solvent at 70°C. Various carbohydrazides could be applied to this protocol, and the desired 2-pyridone products were isolated in excellent yields by simple filtration. This method has several additional advantages, such as simple operation, mild reaction conditions, simple work up, easy product isolation, and preparation of potentially bioactive compounds.

Publisher: name: Zenodo
Year: 2018

description: One of the projects for 2018 within the Consortium of European Social Science Data Archives (CESSDA) is the DataverseEU project. The aim of the project is to develop a service for CESSDA Service Providers, based on the Dataverse software developed by the Institute for Quantitative Social Science (IQSS) at Harvard University, which would be adjusted to the needs of the CESSDA community, especially small and/or emerging archives. To fulfill this, additional functionalities of the Dataverse software are planned to be developed within the project. Project activities in 2018 include the installation of the software using a Docker container on the CESSDA cloud platform, the enhancement of the system to enable connection with a chosen persistent identifier (PID) provider, the development of an API for the CESSDA controlled vocabularies, topic classification, European Language Social Science Thesaurus (ELSST), and the development of a multilingual user interface. Activities in 2019 are aiming to expand the metadata fields towards the DDI lifecycle, to develop different interfaces for national long-term preservation solutions and more. Project partners are: Slovenian Social Science Data Archives (Arhiv družboslovnih podatkov -- ADP), Austrian Social Science Data Archive (AUSSDA), Data Archiving and Networked Services (DANS -- the Netherlands), GESIS -- Leibniz-Institute for the Social Sciences (Germany), Swedish National Data Service (SND), and The Tárki Data Archive (Hungary). The presentation will focus on the ideas behind the project and the initial project results.
Packable Architecture : investigating and prototyping a deployable nature experience within the (sub)urban context
Creators: name: Allida, Joanna
Publisher: name: The University of British Columbia
Year: 2023

description: This project examines issues regarding hypertechnicality, standardization and opacity of modern tent design through a construction and material lens. By prototyping, mainly sewing and model-making, the project aims to address how the tent can be a device to mindfully reconnect humans to all degrees of nature whether that is in urban, suburban or remote conditions. It investigates a niche typology of (sub)urban tents through a system titled the Skinwalker—a soft packable structure that is intended for people who may not have easy access to high levels of nature. By allowing the user to directly manipulate visual connections through framing and scaling, the goal of the system is to elicit similar connections to a remote nature experience within the (sub)urban context.

description: Based on the new general framework for the probabilistic description of experiments, introduced in quant-ph/0305126, quant-ph/0312199, we analyze in mathematical terms the link between the validity of Bell-type inequalities under joint experiments upon a system of any type and the physical concept of "local realism". We prove that the violation of Bell-type inequalities in the quantum case has no connection with the violation of "local realism". In a general setting, we formulate in mathematical terms a condition on "local realism" under a joint experiment and consider examples of quantum "locally realistic" joint experiments. We, in particular, show that quantum joint experiments of the Alice/Bob type are "locally realistic". For an arbitrary bipartite quantum state, we derive quantum analogs of the original Bell inequality. In view of our results, we argue that the violation of Bell-type inequalities in the quantum case cannot be a valid argument in the discussion on locality or non-locality of quantum interactions.

description: Sleep apnea is a breathing disorder where a person repeatedly stops breathing in sleep. Early detection is crucial for infants because it might bring long term adversities. The existing accurate detection mechanism (pulse oximetry) is a skin contact measurement. The existing non-contact mechanisms (acoustics, video processing) are not accurate enough. This paper presents a novel algorithm for the detection of sleep apnea with video processing. The solution is non-contact, accurate and lightweight enough to run on a single board computer. The paper discusses the accuracy of the algorithm on real data, advantages of the new algorithm, its limitations and suggests future improvements.

description: We present a study of the hard X-ray spectrum (>15 keV) of different classes of Seyfert galaxies observed with BeppoSAX/PDS. Using hard X-ray data, we avoid absorption effects modifying the Seyfert emission and have direct access to the central engine of these sources. The aim of this study is first to characterize the general properties of the hard X-ray spectrum of Seyfert 1, 1.5 and 2 galaxies and secondly to compare their intrinsic emission to test unified models according to which all the classes have the same nucleus. We compute the average spectrum of 14 Sy 1, 9 Sy 1.5 and 22 Sy 2 galaxies observed by the PDS (15-136 keV). The average spectrum of Sy 1 differs from that of Sy 2, the first requiring the presence of a high energy cutoff which is absent in the second. We also show that the reflection component is possibly more important in the Sy 2 emission. The nature of Sy 1.5 galaxies is ambiguous as they have a negligible reflection component (like Sy 1) and do not require a cutoff (like Sy 2)

description: We present a graph-theoretic characterisation of when a quantum spin model admits an exact solution via a mapping to free parafermions. Our characterisation is based on the concept of a frustration graph, which represents the commutation relations between Weyl operators of a Hamiltonian. We show that a quantum spin system has an exact free-parafermion solution if its frustration graph is an oriented indifference graph. Further, we show that if the frustration graph of a model can be dipath oriented via switching operations, then the model is integrable in the sense that there is a family of commuting independent set charges. Additionally, we establish an efficient algorithm for deciding whether this is possible. Our characterisation extends that given for free-fermion solvability. Finally, we apply our results to solve three qudit spin models.

description: Building on efforts in the Dataverse community to enhance data documentation, input is required for the development of an interoperable, API-based, data curation application built using the DDI standard in Dataverse (an open-source data repository developed by Institute for Quantitative Social Science (IQSS) at Harvard University). As datasets are deposited by researchers for publication using the Dataverse system, dataset and variable-level metadata are stored to enable discovery, access, and preservation of data. To further this, we outline how a data curation application can be developed to support metadata editing and enrichment that will interoperate with components of the Dataverse system, including the Data Explorer visualization tool, and beyond. A web-based data curation application can work with tabular datasets uploaded to Dataverse, allowing curators to edit and create DDI standard metadata to assist with end-user reuse of the data. The focus for this curation tool will be to enable data depositors -- researchers, data managers, curators, etc. -- to create metadata at the dataset and variable-level, that will enhance reproducibility and reuse of datasets published. DDI supports metadata description of granular research data elements which can be stored as identifiable and reusable objects in Dataverse.

Atoniomyia

description: Atoniomyia Hermann
 Atonia Williston, 1889: 257. (preocc. Gistel, 1848). Type species: mikii Williston (Williston, 1901: 316).
 Atoniomyia Hermann, 1912: 81. (nom. nov. for Atonia Williston). Type species: mikii Williston (aut. as mickii, err).
 Remarks. This largely Neotropical genus consists of 16 species, one of which is Neartic (Martin & Papavero, 1970). It is distinguished by its small (6–7 mm) robust body, strongly punctate scutum and abdominal tergites, short, appressed setae, and the terminalia are concealed by the cup-shaped tergite 6. The flagellum has an apical, down-turned scape with microsegment at its base. Species perch on soil near streams or low on vegetation near ground level (Fisher and Hespenheide, 1992; Fisher, in press). We report 2 females of an undescribed species and A. mikii (Williston) from Azua and Barahona provinces in the Dominican Republic.

Cortical Dynamics and Awareness State: An Interpretation of Observed Interstimulus Interval Dependence in Apparent Motion

description: In a recent paper on Cortical Dynamics, Francis and Grossberg raise the question how visual forms and motion information are integrated to generate a coherent percept of moving forms? In their investigation of illusory contours (which are, like Kanizsa squares, mental constructs rather than stimuli on the retina) they quantify the subjective impression of apparent motion between illusory contours that are formed by two subsequent stimuli with delay times of about 0.2 second (called the interstimulus interval ISI). The impression of apparent motion is due to a back referral of a later experience to an earlier time in the conscious representation. A model is developed which describes the state of awareness in the observer in terms of a time dependent Schroedinger equation to which a second order time derivative is added. This addition requires as boundary conditions the values of the solution both at the beginning and after the process. Satisfactory quantitative agreement is found between the results of the model and the experimental results. We recall that in the von Neumann interpretation of the collapse of the quantum mechanical wave-function, the collapse was associated with an observer's awareness. Some questions of causality and determinism that arise from later-time boundary conditions are touched upon.

description: In the current study, we employed density functional theory (DFT) calculations to probe the adsorption properties of methylmercaptan (MM), as a toxic gas that could be harmful to human health and environment, with carbon graphene, Ni-decorated, and Pt-decorated graphene. After full optimization of all structures, the obtained results demonstrated that, pristine graphene has a low capacity for adsorbing MM molecules with the adsorption energy of −0.022 KJ/mol while decorating it with nickel and then platinum increases the adsorption energy to −472.8 and −357 KJ/mol for Ni-graphene/MM and Pt-graphene/MM structures, respectively. Furthermore, DOS (density of state) calculations and Mulliken charge analyses were done to consider the electronic properties of the simulated systems. The obtained results revealed stronger adsorption and more transferred charge between MM and both decorated graphene sheets compared to MM/graphene system and the Ni atom has more potential to raise the MM adsorption capacity of graphene than Pt.
Naturally Dangerous: Kratom: Marketed without registration, risky for health

description: Kratom (Mitragyna speciosa) is a plant native to Southeast Asia, known for its stimulant and opioid-like effects. In Asian cultures, it has been used to relieve pain and help manage opioid withdrawal. In recent years, kratom has gained popularity in Western countries as an alternative to prescription opioids and as a recreational substance. However, its increasing use has raised concerns about its safety, including dependence, addiction, and toxicity. Additionally, various cases have been reported discussing the potential risks associated with kratom use and withdrawal. Below are two clinical cases that exemplify the risks linked to its consumption and the abrupt discontinuation of kratom, highlighting the need for regulation.
Updating the classics: A new life for old data

description: In 2016, a great and unexpected storm hit the UK for the first time since back in the 1970s. In the aftermath, some learned researchers set out to find clues to what had changed between then and now, and how life was back then. The researchers asked an intrepid band of data curators to help them, because the old datasets were dusty and written in a language none of them could read. The curators laboured long and hard to write scripts and routines to convert column binary data to modern-day statistical formats, often with little information to go on. They knew about the Data Rescue Interest Group (https://www.rd-alliance.org/groups/data-rescue.html) and all the valiant work they do, but faced a different challenge. These data were born digital rather than paper-based, but still could not be easily used. After many hours of painstaking work, over 100 datasets were born again, helping the researchers find out about public opinion at the time of the "first" UK-EU Referendum of 1975. Come and hear about our adventures along the way, enhancing data science skills, upgrading documents, and developing format migration strategies

description: The scalar dark matter candidate in a prototypical theory space little Higgs model is investigated. We review all details of the model pertinent to dark matter. We perform a thermal relic density calculation including couplings to the gauge and Higgs sectors of the model. We find two regions of parameter space that give acceptable dark matter abundances. The first region has a dark matter candidate with a mass of order 100 GeV, the second region has a heavy candidate with a mass greater than about 500 GeV$. The dark matter candidate in either region is an admixture of an SU(2) triplet and an SU(2) singlet, thereby constituting a WIMP (weakly interacting massive particle).

description: We show that a simple experimental setting of a locally pumped and lossy array of two-level quantum systems can stabilize states with strong long-range coherence. Indeed, by explicit analytic construction, we show there is an extensive set of steady-state density operators, from minimally to maximally entangled, despite this being an interacting open many-body problem. Such nonequilibrium steady states arise from a hidden symmetry that stabilizes Bell pairs over arbitrarily long distances, with unique experimental signatures. We demonstrate a protocol by which one can selectively prepare these states using dissipation. Our findings are accessible in present-day experiments.

description: Thiophene is a core structure in many marketed drugs, such as Duloxetine, Tiotropium, Raloxifene, Dorzolamide, Tioconazole, Citizolam, Sertaconazole Nitrate and Benocyclidine. Thiophene derivatives are reported to have several types of pharmacological and biological activities. The synthesis of new thiophene derivatives is important to pharmaceutical research, because of their diverse pharmacological activities. The reaction of ethyl 3-oxobutanoate with carbon disulfide and chloroacetone in the presence of K2CO3 affords the unexpected thiophene derivative 7. Furthermore, refluxing compound 7 with dimethylformamide-dimethylacetal (DMF-DMA) in DMF affords the enaminone derivative 8. The structures of these newly synthesized compounds were confirmed by means of various spectroscopic techniques, such as IR, MS, and NMR, as well as by X-ray diffraction. In addition, B3LYP/6-311G(d, p) basis sets were employed to optimize the molecular geometry of the two thiophene derivatives. Furthermore, natural atomic charges and frontier molecular orbital analyses were performed. Hirshfeld analysis of the molecular packing showed that H—H, O—H, C—H, and S—H are the most common intermolecular interactions in both compounds. Further analysis suggests that the O—H interactions are the most significant of these in compounds 7 and 8.

description: The purpose of this article is to study the IT-related issues during Merger and Acquisition (M&A). A case study between International Food Group and Glow-Foods is espoused. Earlier, the major problems in M&A were different than IT. But, in the 21st century, with the amount of data and its privacy, IT plays a significant role during acquisitions. The objective is to summarize two research questions proposed at the end of the mini-case study (Mckeen & Smith, 2015, p. 238). The reader will learn the significant obstacles that IT managers experience during M&A. The reader will also understand the three-point innovations plan that Josh’s team prepare after a deep dive into stringent guidelines of the acquiring company. The paper concludes with the success of hatching the innovations under the strict guidelines by tackling chief technology officer, architecture head, marketing liaison, chief finance officer, and many more.
