description: This paper presents a new reward function that can be used for deep reinforcement learning in unmanned aerial vehicle (UAV) control and navigation problems. The reward function is based on the construction and estimation of the time of simplified trajectories to the target, which are third-order Bezier curves. This reward function can be applied unchanged to solve problems in both two-dimensional and three-dimensional virtual environments. The effectiveness of the reward function was tested in a newly developed virtual environment, namely, a simplified two-dimensional environment describing the dynamics of UAV control and flight, taking into account the forces of thrust, inertia, gravity, and aerodynamic drag. In this formulation, three tasks of UAV control and navigation were successfully solved: UAV flight to a given point in space, avoidance of interception by another UAV, and organization of interception of one UAV by another. The three most relevant modern deep reinforcement learning algorithms, Soft actor-critic, Deep Deterministic Policy Gradient, and Twin Delayed Deep Deterministic Policy Gradient were used. All three algorithms performed well, indicating the effectiveness of the selected reward function.

description: Using a photonic quantum computer for boson sampling has been demonstrated a tremendous advantage over classical supercomputers. It is highly desirable to develop boson sampling algorithms for realistic scientific problems. In this work, we propose a hybrid quantum-classical sampling (HQCS) algorithm to calculate the optical spectrum for complex molecules considering anharmonicity and Duschinsky rotation (DR) effects. The classical sum-over-state method for this problem has a computational complexity that exponentially increases with system size. In the HQCS algorithm, an intermediate harmonic potential energy surface (PES) is created, bridging the initial and final PESs. The magnitude and sign (-1 or +1) of the overlap between the initial state and the intermediate state are estimated by quantum boson sampling and by classical algorithms respectively, achieving an exponential speed-up. Additionally, the overlap between the intermediate state and the final state is efficiently evaluated by classical algorithms. The feasibility of HQCS is demonstrated in calculations of the emission spectrum of a Morse model as well as pyridine molecule by comparison with the nearly exact time-dependent density matrix renormalization group solutions. A near-term quantum advantage for realistic molecular spectroscopy simulation is proposed.

description: A total of 120 samples were collected from patients and sites in paediatric wards from Irrua Specialist TachingHospital Irrua. In all, 12 samples were collected from different paediatric wards, 24 were from nurses uniform and 48 samples which were from infants in paediatric wards included blood, mid stream urine and ear swabs.All the samples were then cultured in duplicates onto blood agar, McConkey agar, chocolate agar, mannitolsalt agar, cystein lactose electrolyte deficient medium. All the samples yielded bacterial growth which included Staphylococcus aureus which was the most predominant (78%), other isolates included Pseudomonas aeruginosa(8%), Proteus mirabilis(6%), Escherichia coli (4%), Streptococcus faecalis(3%) and Candida albicans(1%).Staphylococcus aureusis still a major cause of nosocomial infections. The fact that most of the organisms isolated were resistant to most of the currently used antibiotics present a major public health problem. Hence a high hygienic standard must be maintained in the wards. And nurses should disinfect themselves before and after seeing each patient so as to minimize the transfer of this microorganisms from patient to patient via the nurses.

description: We present a comprehensive study of enantioselective orientation of chiral molecules excited by a pair of delayed cross-polarized femtosecond laser pulses. We show that by optimizing the pulses' parameters, a significant (~ 10%) degree of enantioselective orientation can be achieved at zero and at five kelvin rotational temperatures. This study suggests a set of reasonable experimental conditions for inducing and measuring strong enantioselective orientation. The strong enantioselective orientation and the wide availability of the femtosecond laser systems required for the proposed experiments may open new avenues for discriminating and separating molecular enantiomers.

description: Excerpts from the Introduction: Cotton has been, and remains, a very significant part of the U.S. economy, but market supply, disappearance, and prices have fluctuated widely during the past several decades. The leadership of cotton as a raw material for the U.S. textile industry is being challenged by manmade fibers, and cotton industry leaders are increasingly concerned about this competition. In addition, the industry is faced with rising costs, competition from foreign cottons for export outlets, the problem of maintaining and improving quality, the need to find and promote new uses and markets for cotton, and competition from manmade fibers, plastics, paper, and other raw materials. Changes in technology are constantly being made at all stages of the marketing systems for cotton and cotton textile products. Associated with these developments are changes in market structure and organization, and in efficiencies of providing marketing services. In addition, the ever-changing character of consumer demand for textile products greatly influences the cotton and cotton-products industries. An evaluation of these changes should help in understanding problems confronting the U.S. cotton industry, and in appraising prospective developments in marketing which may strengthen the competitive position of U.S. cotton.

description: We derive a formula for the dry adiabatic lapse rate of atmospheres composed of real gases. We restrict our study to those described by a family of two-parameter cubic equations of state and the recent Guevara non-cubic equation. Since our formula depends on the adiabatic curves, we compute them all at once, considering molecules that can move, rotate, and vibrate, for any equation of state. To illustrate our results, we estimate the lapse rate of the troposphere of Titan, obtaining a better approximation to the observed data in some instances, when compared to the estimation provided by the virial expansion up to third order.

description: Bibliotheken bieten auch technisch Unkundigen einen demokratischen, nicht-kommerziellen Rahmen für das Ausprobieren neuer technischer Trends. Angesichts des sich entwickelnden Video-Streaming-Markts und zurückgehender DVD-Entleihungen wurde in der Stadtbibliothek Köln der Dienst filmfriend eingeführt, allerdings erst nachdem ein für beide Seiten akzeptables Lizenzmodell gefunden wurde. Filmstreaming ist zwar kein Ersatz für einen umfangreichen DVD-Bestand, aber die zeit- und ortsunabhängige parallele Zugriffsmöglichkeit bringt für die Bibliotheksmitglieder eine erhebliche Komfortsteigerung mit sich – nicht nur in Pandemiezeiten. Vor allem aber handelt es sich trotz der begrenzten Titelauswahl um ein imagestärkendes Angebot, das man von Bibliotheken so nicht erwartet und das sich sehr gut in weitere Bibliotheksaktivitäten einfügt – von pädagogisch begleiteten Vermittlungsaktionen bis hin zum Selbermachen im 2020 in der Stadtbibliothek Köln eröffneten Studio für YouTube-Videos.
description: Libraries provide a democratic, commercial-free space to try out new technological trends, even for technology novices. In light of the burgeoning streaming sector and the decline in DVD circulation, the Cologne Public Library, after negotiating a mutually acceptable licensing model, added the streaming service filmfriend. Although film streaming is not a replacement for an extensive DVD collection, it does considerably increase the comfort for library patrons by enabling parallel access to titles independent of time and location—not only during a pandemic. Above all, it boosts the Library’s image, despite the limited selection of titles. The streaming service is something unexpected for a library, and yet it fits in very well with other library activities, from pedagogically guided educational activities to do-it-yourself activities in the Library’s newly opened studio for YouTube videos.
Hybrid of monolithic and staggered solution techniques for the computational analysis of fracture, assessed on fibrous network mechanics

description: The computational analysis of fiber network fracture is an emerging field with application to paper, rubber-like materials, hydrogels, soft biological tissue, and composites. Fiber networks are often described as probabilistic structures of interacting one-dimensional elements, such as truss-bars and beams. Failure may then be modeled as strong discontinuities in the displacement field that are directly embedded within the structural finite elements. As for other strain-softening materials, the tangent stiffness matrix can be non-positive definite, which diminishes the robustness of the solution of the coupled (monolithic) two-field problem. Its uncoupling, and thus the use of a staggered solution method where the field variables are solved alternatingly, avoids such difficulties and results in a stable, but sub-optimally converging solution method. In the present work, we evaluate the staggered against the monolithic solution approach and assess their computational performance in the analysis of fiber network failure. We then propose a hybrid solution technique that optimizes the performance and robustness of the computational analysis. It represents a matrix regularization technique that retains a positive definite element stiffness matrix while approaching the tangent stiffness matrix of the monolithic problem. The approach is general and may also accelerate the computational analysis of other failure problems.

description: Computational notebooks -- such as Jupyter or Colab -- combine text and data analysis code. They have become ubiquitous in the world of data science and exploratory data analysis. Since these notebooks present a different programming paradigm than conventional IDE-driven programming, it is plausible that debugging in computational notebooks might also be different. More specifically, since creating notebooks blends domain knowledge, statistical analysis, and programming, the ways in which notebook users find and fix errors in these different forms might be different. In this paper, we present an exploratory, observational study on how Python Jupyter notebook users find and understand potential errors in notebooks. Through a conceptual replication of study design investigating the error identification strategies of R notebook users, we presented users with Python Jupyter notebooks pre-populated with common notebook errors -- errors rooted in either the statistical data analysis, the knowledge of domain concepts, or in the programming. We then analyzed the strategies our study participants used to find these errors and determined how successful each strategy was at identifying errors. Our findings indicate that while the notebook programming environment is different from the environments used for traditional programming, debugging strategies remain quite similar. It is our hope that the insights presented in this paper will help both notebook tool designers and educators make changes to improve how data scientists discover errors more easily in the notebooks they write.

description: The marketing system for dairy products has been in the process of change ever since it began to be organized on a commercial basis a century ago. It has changed in organization, methods of operation, and efficiency. To a substantial degree, these changes are responses to changes taking place on the farm and in the household. Adjustments at one level have repercussions throughout the marketing system and these, in turn, have effects on the producer and the consumer. The marketing system provides for the flow of products from the farmer to the consumer and for the flow of information about consumer preferences and wants back from the consumer through the marketing system to the farmer.

description: Buoyancy is a well-known effect in immiscible binary Bose-Einstein condensates. Depending on the differential confinement experienced by the two components, a bubble of one component sitting at the center of the other eventually floats to the surface, around which it spreads either totally or partially. We discuss how quantum fluctuations may significantly change the volume and position of immiscible bubbles. We consider the particular case of two miscible components, forming a pseudo-scalar bubble condensate with enhanced quantum fluctuations (quantum bubble), immersed in a bath provided by a third component, with which they are immiscible. We show that in such a peculiar effective binary mixture, quantum fluctuations change the equilibrium of pressures that define the bubble volume and modify as well the criterion for buoyancy. Once buoyancy sets in, in contrast to the mean-field case, quantum fluctuations may place the bubble at an intermediate position between the center and the surface. At the surface, the quantum bubble may transition into a floating self-bound droplet.

description: We develop an analytical description of static ferrodark solitons, the $\mathbb{Z}_2$ topological defects in the magnetic order, in the easy-plane phase of ferromagnetic spin-1 Bose-Einstein condensates. We find that the type-I ferrodark soliton has a single width while the type-II ferrodark soliton exhibits two characteristic length scales. The proposed ansatzes show excellent agreement with numerical results. Spin-singlet amplitudes, nematic tensor densities and nematic currents of ferrodark solitons are also discussed. The $\mathbb{Z}_2$ topological defects in the mass superfluid order, dark-dark-dark vector solitons, are obtained exactly in the parameter regime where exact ferrodark solitons exist. The dark-dark-dark vector soliton has higher excitation energy than ferrodark solitons.

description: Inclusion complexation of ciprofloxacin (CIP), sparfloxacin (SPA), and ofloxacin (OFL) drugs with α-CD and β-CD was studied by UV-visible, fluorescence, time-resolved fluorescence, Fourier transform infrared spectroscopy (FTIR), hydrogen nuclear magnetic resonance (1HNMR), scanning electron microscopy (SEM), and molecular modelling techniques. Changes in the absorbance and fluorescence intensities and fluorescence lifetime of the drugs in the cyclodextrin (CD) solutions suggest the formation of inclusion complexes. Carbonyl stretching frequency moved to higher wave numbers and broadening of the N–H stretching band indicated the formation of inclusion complex. Cyclohexane ring protons of the drugs show remarkable upfield or downfield shift in the 1HNMR spectrum, indicating that the cyclohexane part of the guest molecule is entrapped inside CD cavities. SEM images of CIP/CD, SPA/CD, and OFL/CD complexes have a crystal structure with different morphology from the isolated CIP, SPA, OFL, and CDs. Investigations of the energetic, thermodynamic, and electronic properties of parametric model number 3 computational calculations confirmed the stability of the inclusion complex.
Studies on the Kinesin-9 family in motile cilia formation and function

description: Kinesins are microtubule-based motors that are an integral part of basic cell biological processes. From driving intracellular transport along microtubules, to orchestrating chromosome segregation during mitosis, and finally to building specialized organelles such as the cilium, the 45 mammalian kinesins have adopted specific functions in vivo during the development of the organism. In this work, we defined the roles of the Kinesin-9 family, Kif6 and Kif9, in vivo in motile cilia. Motile cilia are microtubule-based, whip-like projections on multiciliated cells that function in fluid flow and cell motility in single cells, such as sperm. We have performed extensive genetic analysis of KIF6 in human, mouse, and zebrafish. By modeling a KIF6 allele found in a human patient with intellectual disabilities, we revealed a role in ependymal cell ciliogenesis in the mouse. While ependymal cell cilia are reduced in the Kif6 mouse mutant, we did not observe similar defects in other multiciliated cell types. Analysis of kif6 mutant zebrafish further confirmed an evolutionarily conserved role in ependymal cell cilia formation. Together these data suggest Kif6 may be a tissue specific kinesin required for ependymal cell ciliogenesis. On the other hand, we have performed an extensive cell biological analysis of Kif9 in Xenopus laevis multiciliated cells to reveal a specific role in ciliary motility. Loss of Kif9 leads to a reduction in every known ciliary motility complex from the distal tip of motile cilia. Our in vitro analysis shows that Kif9 is a slowly processive motor along microtubules with a speed of ~8nm/second, while we observe no processivity in vivo in multiciliated cells. These data suggest that Kif9 is contributing to ciliary beating through a force generation mechanism, similar to other motor proteins in the cilium, while also contributing to the localization of other motility complexes in the cilium. Our work highlights the importance of in vivo analysis of kinesins, and further defines the functions of the Kinesin-9 family.

description: To interpret molecular dynamics simulations of biomolecular systems, systematic dimensionality reduction methods are commonly employed. Among others, this includes principal component analysis (PCA) and time-lagged independent component analysis (TICA), which aim to maximize the variance and the timescale of the first components, respectively. A crucial first step of such an analysis is the identification of suitable and relevant input coordinates (the so-called features), such as backbone dihedral angles and interresidue distances. As typically only a small subset of those coordinates is involved in a specific biomolecular process, it is important to discard the remaining uncorrelated motions or weakly correlated noise coordinates. This is because they may exhibit large amplitudes or long timescales and therefore will be erroneously be considered important by PCA and TICA, respectively. To discriminate collective motions underlying functional dynamics from uncorrelated motions, the correlation matrix of the input coordinates is block-diagonalized by a clustering method. This strategy avoids possible bias due to presumed functional observables and conformational states or variation principles that maximize variance or timescales. Considering several linear and nonlinear correlation measures and various clustering algorithms, it is shown that the combination of linear correlation and the Leiden community detection algorithm yields excellent results for all considered model systems. These include the functional motion of T4 lysozyme to demonstrate the successful identification of collective motion, as well as the folding of villin headpiece to highlight the physical interpretation of the correlated motions in terms of a functional mechanism.

description: We use string field theory to fix the normalization of the D-instanton corrections to the superpotential involving the moduli fields of type II string theory compactified on an orientifold of a Calabi-Yau threefold in the absence of fluxes. We focus on $O(1)$ instantons whose only zero modes are the four bosonic modes associated with translation of the instanton in non-compact directions and a pair of fermionic zero modes associated with the two supercharges broken by the instanton. We work with a generic superconformal field theory and express our answer in terms of the spectrum of open strings on the instanton. We analyse the contribution of multi-instantons of this kind to the superpotential and argue that it vanishes when background fluxes are absent.

description: Liquid–liquid equilibrium (LLE) data for the quaternary systems (water + ethanol + dichloromethane (DCM) or chloroform (CHCl3) + diethyl ether (DEE)) were experimentally investigated at 293.15 K. The thermodynamic consistency of the data was performed using the Othmer–Tobias and Hand plots. The experimental tie-line data were correlated using the non-random, two-liquid (NRTL) model. As a result, the comparison of the extracting capabilities of the mixed solvents with respect to the distribution coefficients and separation factors showed that the (50% DCM +50% DEE) system had a higher separation factor for the (water + ethanol + DCM + DEE) system. On the other hand, the (50% CHCl3 +50% DEE) system had a higher separation factor for the (water + ethanol + CHCl3 + DEE) system. The last solvent (50% CHCl3 +50% DEE) was found to be the best solvent, with a positive synergistic effect on DEE, high separation factor, and very low solubility in water.
Diverse Exotic Orders and Fermiology in Fe-based Superconductors: A Unified Mechanism for $B_{1g}/B_{2g}$ Nematicity in FeSe/(Cs,Rb)Fe$_2$As$_2$ and Smectic Order in BaFe$_2$As$_2$

description: A rich variety of nematic/smectic orders in Fe-based superconductors is an important unsolved problem in strongly correlated electron systems. A unified understanding of these orders has been investigated for the last decade. In this article, we explain the $B_{1g}$ symmetry nematic transition in FeSe$_{1-x}$Te$_x$, the $B_{2g}$ symmetry nematicity in AFe$_2$As$_2$ (A=Cs, Rb), and the smectic state in BaFe$_2$As$_2$ based on the same framework. We investigate the quantum interference mechanism between spin fluctuations by developing the density wave equation. The observed rich variety of nematic/smectic orders is naturally understood in this mechanism. The nematic/smectic orders depend on the characteristic shape and topology of the Fermi surface (FS) of each compound. (i) In FeSe$_{1-x}$Te$_x$, each FS is very small and the dxy-orbital hole pocket is below the Fermi level. In this case, the small spin fluctuations on three dxz, dyz, and dxy orbitals cooperatively lead to the $B_{1g}$ nematic order. The experimental Lifshitz transition below the nematic transition temperature $(T_S)$ is naturally reproduced. (ii) In BaFe$_2$As$_2$, the dxy-orbital hole pocket emerges around M point, and each FS is relatively large. The strong spin fluctuations due to the dxy-orbital nesting give rise to the $B_{1g}$ nematic order and the smectic order, and the latter transition temperature ($T^*$) exceeds the former one $T_S$. (iii) In heavily hole-doped AFe$_2$As$_2$, the large dxy-orbital hole pocket and the four tiny Dirac pockets appear due to the hole-doping. The $B_{2g}$ nematic bond order emerges on the dxy-orbital hole pocket due to the same interference mechanism. The present paramagnon interference mechanism provides a unified explanation of why the variety of nematic/smectic orders in Fe-based superconductors is so rich, based on the well-established fermiology of Fe-based superconductors.

description: Excerpts from the report Summary: Production of U.S. fats and oils more than doubled during the past two decades, and the Nation became a net exporter instead of a net importer. The market also reflected the changes that affected other farm products. The industry underwent changes in organization and structure; processing methods and techniques; size, type, and number of mills processing the various oilseeds; the volume of different fats and oils produced and their disposition and utilization in domestic and foreign outlets, particularly following World War II. This country's change from a net importing to a net exporting country was emphatic. By the midsixties, U.S. production accounted for more than one-fourth of the world's total supply of fats and oils. Before World War II, it was about 5 percent of the total. In contrast to the increase in production, per capita consumption of fats and oils in the United States changed little, remaining at about 70 pounds during the past several decades. Important technological developments have occurred in the fats and oils industries during the past 20 years or so. The shift in the oilseed crushing industry from the hydraulic method of extracting to the more efficient screw-press, solvent, and prepress-solvent methods was one of the more significant developments. It was a major factor in the trend toward fewer but larger mills, and in the increase in oil yields per unit of raw material processed. The hydrogenation of fats and oils was also an important technological achievement, making possible a wider use of some oils.

description: Automated relation extraction (RE) from biomedical literature is critical for many downstream text mining applications in both research and real-world settings. However, most existing benchmarking datasets for bio-medical RE only focus on relations of a single type (e.g., protein-protein interactions) at the sentence level, greatly limiting the development of RE systems in biomedicine. In this work, we first review commonly used named entity recognition (NER) and RE datasets. Then we present BioRED, a first-of-its-kind biomedical RE corpus with multiple entity types (e.g., gene/protein, disease, chemical) and relation pairs (e.g., gene-disease; chemical-chemical) at the document level, on a set of 600 PubMed abstracts. Further, we label each relation as describing either a novel finding or previously known background knowledge, enabling automated algorithms to differentiate between novel and background information. We assess the utility of BioRED by benchmarking several existing state-of-the-art methods, including BERT-based models, on the NER and RE tasks. Our results show that while existing approaches can reach high performance on the NER task (F-score of 89.3%), there is much room for improvement for the RE task, especially when extracting novel relations (F-score of 47.7%). Our experiments also demonstrate that such a rich dataset can successfully facilitate the development of more accurate, efficient, and robust RE systems for biomedicine.

description: To investigate the molecular interaction study between secondary amine with aryl and alkyl ether, we report densities, speeds of sound, viscosities and refractive indices of N-ethylaniline (NEA) with aryl (anisole, phenetole) and alkyl (tert-butyl methyl ether) ether over the entire composition regime and in the temperature range of 293.15–323.15 K at 5 K intervals. Various excess and transport properties were derived from the experimental data and the excess parameters were fitted to the Redlich–Kister polynomial equation using multiparametric non-linear regression analysis to derive the binary coefficients and to estimate the standard deviation. Molecular interactions between the unlike molecules were analysed through dipole–dipole interactions, cross-association between the components of the mixtures and H-bond formation. Viscosity and refractive index of the mixtures were predicted through several empirical equations and compared with the experimental results. Prigogine–Flory–Patterson statistical theory was used to predict the excess molar volume results.

description: Samples of sludge from the petroleum industry were collected and characterized for their pollution characteristics. The solids concentration, pH, temperature, biochemical oxygen demand, chemical oxygen demand, dissolved oxygen, phosphate, nitrogen, conductivity, calcium, magnesium, sodium, potassium, iron, manganese, lead and chromium were determined. The analysis revealed that the mean value of total solids (TS) content, total suspended solids (TSS) and total volatile solids (TVS) were 1987, 1050 and 937 mg/l respectively. The dissolved oxygen (DO) content was 3.7 mg/l. The biological oxygen demand (BOD) and chemical oxygen demand (COD) were 518 and 1345 mg/l, respectively. The total nitrogen and phosphorus contents were 3.4 and 2.3 mg/l respectively. The total bacteria counts were 7.4 x 108 /100 ml. All these values exceed those of the standard as set by World Health Organisation (WHO) for potable water. This shows that the sludge has high pollution potentials and so need treatment before disposal. The COD:BOD ratio was 2.60 which indicated that the sludge can undergo biodegradation and suggests that biological method could be used in effecting treatment to the sludge. The high conductivity also indicated that the sludge can be treated by physicochemical method of coagulation and flocculation.
