description: Malaria parasites in the blood stage express a single transmembrane transport protein for the release of the glycolytic end product l-lactate/H+ from the cell. This transporter is a member of the strictly microbial formate-nitrite transporter (FNT) family and a novel putative drug target. Small, drug-like FNT inhibitors potently block lactate transport and kill Plasmodium falciparum parasites in culture. The protein structure of Plasmodium falciparum FNT (PfFNT) in complex with the inhibitor has been resolved and confirms its previously predicted binding site and its mode of action as a substrate analog. Here, we investigated the mutational plasticity and essentiality of the PfFNT target on a genetic level, and established its in vivo druggability using mouse malaria models. We found that, besides a previously identified PfFNT G107S resistance mutation, selection of parasites at 3 × IC50 (50% inhibitory concentration) gave rise to two new point mutations affecting inhibitor binding: G21E and V196L. Conditional knockout and mutation of the PfFNT gene showed essentiality in the blood stage, whereas no phenotypic defects in sexual development were observed. PfFNT inhibitors mainly targeted the trophozoite stage and exhibited high potency in P. berghei- and P. falciparum-infected mice. Their in vivo activity profiles were comparable to that of artesunate, demonstrating strong potential for the further development of PfFNT inhibitors as novel antimalarials.

description: We present a sharp-interface model of two-dimensional ramified growth during quasi-steady electrodeposition. Our model differs from previous modeling methods in that it includes the important effects of extended space-charge regions and nonlinear electrode reactions.

description: Emphasis has been placed on the behavior of ruthenium (Ru) in the evaporation to dryness accident due to the loss of cooling functions (EDLCF) of high-level liquid waste in fuel reprocessing plants. It is because Ru would form volatile compounds such as ruthenium tetroxide (RuO4) and could be released into the environment with other coexisting gasses such as nitric acid (HNO3), water (H2O). To contribute to the safety evaluation of this accident, we experimentally evaluated the decomposition and chemical change behavior of the gaseous RuO4 (RuO4(g)) under the various atmospheric conditions: temperature and composition of coexisting gasses. As a result, the behavior of the RuO4(g) was diverse depending on the atmospheric conditions. In the experiments with the dry air or H2O vapor, decomposition of RuO4(g) was observed. In the experiment with the mixed gas which containing HNO3, almost no decomposition of the RuO4(g) was observed, and chemical form of the RuO4(g) was retained.

description: The quality and surface integrity of machined parts is influenced by residual stresses in the subsurface resulting from cutting operations. These stress characteristics can not only affect functional properties such as fatigue life, but also the process forces during machining. Especially for orthogonal cutting as an appropriate experimental analogy setup for machining operations like milling, different undeformed chip thicknesses cause specific residual stress formations in the subsurface area. In this work, the process-related depth profile of the residual stress in AISI 4140 was investigated and correlated to the resulting cutting forces. Furthermore, an analysis of the microstructure of the cut material was performed, using additional characterization techniques such as electron backscatter diffraction and nanoindentation to account for subsurface alterations. On this basis, the influence of process-related stress profiles on the process forces for consecutive orthogonal cutting strategies is evaluated and compared to the results of a numerical model. The insights obtained provide a basis for future investigations on, e. g., empirical modeling of process forces including the influence of process-specific characteristics such as residual stress.

Chemical abundance study of two strongly s-process enriched post-AGB stars in the LMC: J051213.81-693537.1 and J051848.86-700246.9

description: Context: This paper is part of a larger project in which we study the chemical abundances of extra-galactic post-AGB stars with the ultimate goal of improving our knowledge of the poorly understood AGB third dredge-up mixing processes and s-process nucleosynthesis. Aims: In this paper, we study two carefully selected post-AGB stars in the LMC. The combination of favourable atmospheric parameters for detailed abundance studies and their known distances make these objects ideal probes of the internal AGB third dredge-up and s-process nucleosynthesis in that they provide observational constraints for theoretical AGB models. Methods: We use high-resolution optical UVES spectra to determine accurate stellar parameters and perform detailed elemental abundance studies. Additionally, we use available photometric data to construct SEDs for reddening and luminosity determinations. We then estimate initial masses from theoretical post-AGB tracks. Results: Both stars show extreme s-process enrichment associated with relatively low C/O ratios of about 1.3. We could only derive upper limits of the lead (Pb) abundance which indicate no strong Pb overabundances with respect to other s-elements. Comparison with theoretical post-AGB evolutionary tracks in the HR-diagram reveals that both stars have low initial masses between 1.0 and 1.5 Msun. Conclusion: This study adds to the results obtained so far on a very limited number of s-process enriched post-AGB stars in the Magellanic Clouds. We find an increasing discrepancy between observed and predicted Pb abundances towards lower metallicities for all studied Magellanic Cloud post-AGB stars found so far, as well as moderate C/O ratios. We find that all s-process rich post-AGB stars in the LMC and SMC studied so far, cluster in the same region of the HR-diagram and are associated with low-mass stars with a low metallicity on average.

description: L’articolo vuole indagare il contributo che potrebbe venire dalle riflessioni dei filosofi nella lotta alla pandemia, che finora ha impegnato principalmente scienziati e medici. Tali riflessioni sono solo giochetti intellettuali, un divertissment da salotto o hanno la possibilità di far comprendere meglio la dimensione culturale determinata da questo tragico evento? La filosofia attraverso quella che Hans Jonas ne Il principio responsabilità chiamava l’“euristica della paura”, può promuovere una nuova moralità in grado di esercitare una forma di controllo e di bilanciamento nei confronti di possibili eccessi o sperequazioni della scienza, fondata su competenze sempre più raffinate. D’altro canto una filosofia animata dall’etica può richiamare la politica alle sue responsabilità, affinché non lasci più indietro nessuno, facendosi carico dei destini dell’umanità tutta intera.

This article aims to explore the contribution that philosophers’ reflections could make in the fight against the pandemic, which has so far mainly involved scientists and doctors. Are such reflections merely intellectual games, a drawing-room divertissement, or do they have the potential to help us better understand the cultural dimension determined by this tragic event? Philosophy, through what Hans Jonas in The Responsibility Principle called the 'heuristics of fear', can promote a new morality capable of exercising a form of control and balancing against the possible excesses or inequalities of science, based on increasingly refined skills. On the other hand, a philosophy animated by ethics can call politics to its responsibilities, so that it no longer leaves anyone behind, taking charge of the destiny of all mankind.

Forces acting on a small particle in an acoustical field in a thermoviscous fluid

description: We present a theoretical analysis of the acoustic radiation force on a single small particle, either a thermoviscous fluid droplet or a thermoelastic solid particle, suspended in a viscous and heat-conducting fluid medium. Our analysis places no restrictions on the length scales of the viscous and thermal boundary layer thicknesses $δ_\mathrm{s}$ and $δ_\mathrm{t}$ relative to the particle radius $a$, but it assumes the particle to be small in comparison to the acoustic wavelength $λ$. This is the limit relevant to scattering of sound and ultrasound waves from micrometer-sized particles. For particles of size comparable to or smaller than the boundary layers, the thermoviscous theory leads to profound consequences for the acoustic radiation force. Not only do we predict forces orders of magnitude larger than expected from ideal-fluid theory, but for certain relevant choices of materials, we also find a sign change in the acoustic radiation force on different-sized but otherwise identical particles. This phenomenon may possibly be exploited in handling of submicrometer-sized particles such as bacteria and vira in lab-on-a-chip systems.

description: We introduce a fiber-optic architecture for neural recording without contrast agents, and study its properties theoretically. Our sensor design is inspired by electrooptic modulators, which modulate the refractive index of a waveguide by applying an electric field across an electrooptic core material, and allows recording of the activities of individual neurons located at points along a 10 cm length of optical fiber with 20 um axial resolution, sensitivity down to 100 uV and a dynamic range of up to 1V using commercially available optical reflectometers as readout devices. A key concept of the design is the ability to create an "intensified" electric field inside an optical waveguide by applying the extracellular voltage from a neural spike over a nanoscopic distance. Implementing this concept requires the use of ultrathin high-dielectric capacitor layers. If suitable materials can be found -- possessing favorable properties with respect to toxicity, ohmic junctions, and surface capacitance -- then such sensing fibers could, in principle, be scaled down to few-micron cross-sections for minimally invasive neural interfacing. Custom-designed multi-material optical fibers, probed using a reflectometric readout, may therefore provide a powerful platform for neural sensing.

description: All DNA transactions, including the repair of damaged DNA, take place in the context of a highly organized yet dynamic chromatin. While studies on individual proteins have yielded important insights into the constituent components of DNA repair machineries that evolved in various organisms, it has become abundantly clear that a more complete understanding of the molecular choreography of DNA repair must take into consideration the complex interplay between repair factors and the chromatin milieu in which they operate. This Research Topic collection, termed “DNA damage response in the context of chromatin”, brings together experts at the forefront of this emerging field with a series of authoritative reviews and exciting original articles to provide a timely update on our current understandings of biology at the intersection between chromatin and DNA repair.

description: Abstract
Background: The concept of resilience runs through an array of disciplines, consisting of engineering, public health, ecology, psychology, sociology, disaster management, and business administration. Researchers have tries to explain the relationship amongst connected ideas such as resiliency, adaptability, transformability, and vulnerability but their varied definitions and differences between them remain fuzzy. There are two reasons why resilience theory is important in entrepreneurship. Firstly, researchers generally employ the term resilience to mean consciousness, determination, perseverance, or self-value to justify why some entrepreneurs and their firms achieve better results than their non-resilient counterparts. Secondly, there are cognitive and behavioural entrepreneurial traits that strengthen a firm’s capability to adapt to varying conditions. The aim of this study is to review the literature that intercepts resilience and entrepreneurship. The study will attempt to identify scholarly conversations to construct notions of resilience and entrepreneurship. Therefore, limitations in the current literature will be examined and directions for future studies would be highlighted.Methods: This paper adopted a systematic interdisciplinary review of relevant studies that is patterned using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA).Results: The scholarly works selected from the literature portrayed six emerging colloquies or research tributaries that intercept entrepreneurship and resilience:
 Resilience as a function of entrepreneurial individuals or firms,  Resilience generating entrepreneurial intentions,  Entrepreneurial behaviour boosting organizational resilience and, Resilience in the framework of entrepreneurial failure,  Entrepreneurship and culture, Resilience as a process of recovery and transformation.
Conclusions: This study serves as a backdrop for the emergence of more nuanced debates on the relationship that exists between the various deliberations. In addition, the results can necessitate entrepreneurs towards promoting a constructively sustainable means for socio-economic development.
ACC/AHA guideline update for the management of patients with unstable angina and non-ST-segment elevation myocardial infarction - 2002: Summary article: A report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (Committee on the Management of Patients with Unstable Angina)

description: The American College of Cardiology (ACC)/American Heart Association (AHA) guidelines for the management of unstable angina and non–ST-segment elevation myocardial infarction (UA/NSTEMI) were published in September 2000.1 Since then, a number of clinical trials and observational studies have been published or presented that, when taken together, alter significantly the recommendations made in that document. Therefore, the ACC/AHA Committee on the Management of Patients With Unstable Angina, with the concurrence of the ACC/AHA Task Force on Practice Guidelines, revised these guidelines. These revisions were prepared in December 2001, reviewed and approved, and then published on the ACC World Wide Web site (www.acc.org) and AHA World Wide Web site (www.americanheart.org) on March 15, 2002. The present article describes these revisions and provides further updates in this rapidly moving field. Minor clarifications in the wording of three recommendations that now appear differently from those that were previously published on the ACC and AHA Web sites are noted in footnotes.
Main Sequence Evolution with Layered Semiconvection

description: Semiconvection - mixing that occurs in regions that are stable when considering compositional gradients, but unstable when ignoring them - is shown to have the greatest potential impact on main sequence stars with masses in the range 1.2 - 1.7 solar masses. We present the first stellar evolution calculations using a prescription for semiconvection derived from extrapolation of direct numerical simulations of double-diffusive mixing down to stellar parameters. The dominant mode of semiconvection in stars is layered semiconvection, where the layer height is an adjustable parameter analogous to the mixing length in convection. The rate of mixing across the semiconvective region is sensitively dependent on the layer height. We find that there is a critical layer height that separates weak semiconvective mixing (where evolution is well-approximated by using the Ledoux criterion) from strong semiconvective mixing (where evolution is well-approximated by using the Schwarzschild criterion). This critical layer height is much smaller than the minimum layer height expected from simulations so we predict that for realistic layer heights, the evolution is nearly the same as a model ran with the Schwarzschild criterion. We also investigate the effects of compositional gradient smoothing, finding that it causes convective cores to artificially shrink in the absence of additional mixing beyond the convective boundary. Layered semiconvection with realistic layer heights provides enough such mixing that stars will still evolve as if the Schwarzschild criterion is employed. Finally, we discuss the potential of detecting such semiconvection and its implication on convective core sizes in solar-like oscillators.

description: Having in mind its future extension for theoretical investigations related to charmed nuclei, we develop a relativistic formalism for the nonmesonic weak decay of single-$Λ$ hypernuclei in the framework of the independent-particle shell model and with the dynamics represented by the $(π,K)$ one-meson-exchange model. Numerical results for the one-nucleon-induced transition rates of ${}^{12}_Λ\textrm{C}$ are presented and compared with those obtained in the analogous nonrelativistic calculation. There is satisfactory agreement between the two approaches, and the most noteworthy difference is that the ratio $Γ_{n}/Γ_{p}$ is appreciably higher and closer to the experimental value in the relativistic calculation. Large discrepancies between ours and previous relativistic calculations are found, for which we do not encounter any fully satisfactory explanation. The most recent experimental data is well reproduced by our results. In summary, we have achieved our purpose to develop a reliable model for the relativistic calculation of the nonmesonic weak decay of $Λ$-hypernuclei, which can now be extended to evaluate similar processes in charmed nuclei.

description: The density wave theory for the grand-design two-armed spiral pattern in galaxies is successful in explaining several observed features. However, the long-term persistence of this spiral structure is a serious problem since the group transport would destroy it within about a billion years as shown in a classic paper by Toomre. In this paper we include the low velocity dispersion component, namely gas, on an equal footing with stars in the formulation of the density wave theory, and obtain the dispersion relation for this coupled system. We show that the inclusion of gas makes the group transport slower by a factor of few, thus allowing the pattern to persist longer - for several billion years. Though still less than the Hubble time, this helps in making the spiral structure more long-lived. Further we show that addition of gas is essential to get a stable wave for the observed pattern speed for the Galaxy, which otherwise is not possible for a one-component stellar disc.

description: We have identified anomalous behavior of the escape rate out of the zero-voltage state in Josephson junctions with a high critical current density Jc. For this study we have employed YBa2Cu3O7-x grain boundary junctions, which span a wide range of Jc and have appropriate electrodynamical parameters. Such high Jc junctions, when hysteretic, do not switch from the superconducting to the normal state following the expected stochastic Josephson distribution, despite having standard Josephson properties such as a Fraunhofer magnetic field pattern. The switching current distributions (SCDs) are consistent with nonequilibrium dynamics taking place on a local rather than a global scale. This means that macroscopic quantum phenomena seem to be practically unattainable for high Jc junctions. We argue that SCDs are an accurate means to measure nonequilibrium effects. This transition from global to local dynamics is of relevance for all kinds of weak links, including the emergent family of nanohybrid Josephson junctions. Therefore caution should be applied in the use of such junctions in, for instance, the search for Majorana fermions.

description: As single junction thin-film technologies, both Si heterojunction (HIT) and Perovskite based solar cells promise high efficiencies at low cost. One expects that a tandem cell design with these cells connected in series will improve the efficiency further. Using a self-consistent numerical modeling of optical and transport characteristics, however, we find that a traditional series connected tandem design suffers from low Jsc due to band-gap mismatch and current matching constraints. It requires careful thickness optimization of Perovskite to achieve any noticeable efficiency gain. Specifically, a traditional tandem cell with state-of-the-art HIT (24%) and Perovskite (20%) sub-cells provides only a modest tandem efficiency of ~25%. Instead, we demonstrate that a bifacial HIT/Perovskite tandem design decouples the optoelectronic constraints and provides an innovative path for extraordinary efficiencies. In the bifacial configuration, the same state-of the-art sub-cells achieve a normalized output of 33%, exceeding the bifacial HIT performance at practical albedo reflections. Unlike the traditional design, this bifacial design is relatively insensitive to Perovskite thickness variations, which may translate to simpler manufacture and higher yield.

description: A cluster of risk factors for cardiovascular disease and type 2 diabetes mellitus, which occur together more often than by chance alone, have become known as the metabolic syndrome. The risk factors include raised blood pressure, dyslipidemia (raised triglycerides and lowered high-density lipoprotein cholesterol), raised fasting glucose, and central obesity. Various diagnostic criteria have been proposed by different organizations over the past decade. Most recently, these have come from the International Diabetes Federation and the American Heart Association/National Heart, Lung, and Blood Institute. The main difference concerns the measure for central obesity, with this being an obligatory component in the International Diabetes Federation definition, lower than in the American Heart Association/National Heart, Lung, and Blood Institute criteria, and ethnic specific. The present article represents the outcome of a meeting between several major organizations in an attempt to unify criteria. It was agreed that there should not be an obligatory component, but that waist measurement would continue to be a useful preliminary screening tool. Three abnormal findings out of 5 would qualify a person for the metabolic syndrome. A single set of cut points would be used for all components except waist circumference, for which further work is required. In the interim, national or regional cut points for waist circumference can be used.

description: We follow the time evolution of a superfluid Fermi gas of resonantly interacting $^6$Li atoms after a phase imprint. Via tomographic imaging, we observe the formation of a planar dark soliton, its subsequent snaking, and its decay into a vortex ring, which in turn breaks to finally leave behind a single solitonic vortex. In intermediate stages we find evidence for an exotic structure resembling the $Φ$-soliton, a combination of a vortex ring and a vortex line. Direct imaging of the nodal surface reveals its undulation dynamics and its decay via the puncture of the initial soliton plane. The observed evolution of the nodal surface represents dynamics beyond superfluid hydrodynamics, calling for a microscopic description of unitary fermionic superfluids out of equilibrium.

description: We have investigated the valley degeneracy of MoS2 multilayers and its effect on thermoelectric properties. By modulating the layer thickness and external electric field, the hole valleys at Γ and K points in the highest energy valence band and the electron valleys at K and Σmin points in the lowest energy conduction band are shifted differently. The hole valley degeneracy is observed in MoS2 monolayer, while that of electron valley is in MoS2 bilayer and monolayer under the external electric field. By tuning the valley degeneracy, the Seebeck coefficient and electrical conductivity can be separately controlled, and the maximum power factor can be obtained in n-type (p-type) MoS2 monolayer with (without) the external electric field. We suggest that the transition metal dichalcogenides are good example to investigate the role of valley degeneracy in the thermoelectric and optical properties with the control of interlayer interaction and external electric field strength.

description: The term "Ta'ziyeh" implies an Iranian dramatic genre and is the original drama of the entire Islamic world. This ritual drama has both Islamic and Persian heritage, with the tragic and heroic martyrdom of Imam Husayn as a central theme. The central theme of Ta'ziyeh is the representation of the siege and massacres of Karbala.
Accurately specifying storm-time ULF wave radial diffusion in the radiation belts

description: Ultra-low frequency (ULF) waves can contribute to the transport, acceleration and loss of electrons in the radiation belts through inward and outward diffusion. However, the most appropriate parameters to use to specify the ULF wave diffusion rates are unknown. Empirical representations of diffusion coefficients often use Kp; however, specifications using ULF wave power offer an improved physics-based approach. We use 11 years of ground-based magnetometer array measurements to statistically parameterise the ULF wave power with Kp, solar wind speed, solar wind dynamic pressure and Dst. We find Kp is the best single parameter to specify the statistical ULF wave power driving radial diffusion. Significantly, remarkable high energy tails exist in the ULF wave power distributions when expressed as a function of Dst. Two parameter ULF wave power specifications using Dst as well as Kp provide a better statistical representation of storm-time radial diffusion than any single variable alone.

description: Whereas deep neural networks were first mostly used for classification tasks, they are rapidly expanding in the realm of structured output problems, where the observed target is composed of multiple random variables that have a rich joint distribution, given the input. We focus in this paper on the case where the input also has a rich structure and the input and output structures are somehow related. We describe systems that learn to attend to different places in the input, for each element of the output, for a variety of tasks: machine translation, image caption generation, video clip description and speech recognition. All these systems are based on a shared set of building blocks: gated recurrent neural networks and convolutional neural networks, along with trained attention mechanisms. We report on experimental results with these systems, showing impressively good performance and the advantage of the attention mechanism.

description: The irradiation with fast ions with kinetic energies of > 10 MeV leads to the deposition of a high amount of energy along their trajectory (up to several ten keV/nm). The energy is mainly transferred to the electronic subsystem and induces different secondary processes of excitations which result in significant material modifications. A new setup to study these ion induced effects on surfaces will be described in this paper. The setup combines a variable irradiation chamber with different techniques of surface characterizations like scanning probe microscopy, time-of-flight secondary ion and neutral mass spectrometry, as well as low energy electron diffraction under ultra high vacuum conditions, and is mounted at a beamline of the universal linear accelerator (UNILAC) of the GSI facility in Darmstadt, Germany. Here, samples can be irradiated with high-energy ions with a total kinetic energy up to several GeVs under different angles of incidence. Our setup enables the preparation and in-situ analysis of different types of sample systems ranging from metals to insulators. Time-of-flight secondary ion mass spectrometry enables us to study the chemical composition of the surface, while scanning probe microscopy allows a detailed view into the local electrical and morphological conditions of the sample surface down to atomic scales. With the new setup particle emission during irradiation as well as persistent modifications of the surface after irradiation can thus be studied. We present first data obtained with the new setup, including a novel measuring protocol for time-of-flight mass spectrometry with the GSI UNILAC accelerator.
CHAPTER 21: From Novice to Nurse: Searching For Patient Care Information as Strategic Exploration

description: Introduction:
Nursing librarians partner with educators to ensure that students gain the
skills, knowledge, and aptitudes needed to be both professional nurses and
lifelong learners. Research and the search for best practices drive the current
health care environment, requiring nurses to prove their competency with
information skills for everything from job promotion to care improvement
projects. The literature has consistently shown that nurses need information
regarding medications, treatments, diseases, clinical procedures, and other
point-of-care evidence, as well as patient education materials.1 Despite this
expectation, nurses lack time, search skills, and access to resources necessary
for their information needs. Nursing librarians can anticipate what students
will need to know as practitioners, using the needs and information-seeking
practices of nurses to guide learning objectives for students. Nursing librarians
can work closely with faculty to plan instruction to ensure students know
how to search efficiently and effectively, setting them up for future success as
nurses.
