description: We study the phase transition in a helimagnetic film with Heisenberg spins under an applied magnetic field in the c direction perpendicular to the film. The helical structure is due to the an-tiferromagnetic interaction between next-nearest neighbors in the c direction. Helimagnetic films in zero field are known to have a strong modification of the in-plane helical angle near the film surfaces. We show that spins react to a moderate applied magnetic field by creating a particular spin configuration along the c axis. With increasing temperature (T), using Monte Carlo simulations we show that the system undergoes a phase transition triggered by the destruction of the ordering of a number of layers. This partial phase transition is shown to be intimately related to the ground-state spin structure. We show why some layers undergo a phase transition while others do not. The Green's function method for non collinear magnets is also carried out to investigate effects of quantum fluctuations. Non-uniform zero-point spin contractions and a crossover of layer magnetizations at low T are shown and discussed.

description: Quantum walks have proven to be a universal model for quantum computation and to provide speed-up in certain quantum algorithms. The discrete-time quantum walk (DTQW) model, among others, is one of the most suitable candidates for circuit implementation, due to its discrete nature. Current implementations, however, are usually characterized by quantum circuits of large size and depth, which leads to a higher computational cost and severely limits the number of time steps that can be reliably implemented on current quantum computers. In this work, we propose an efficient and scalable quantum circuit implementing the DTQW on the $2^n$-cycle based on the diagonalization of the conditional shift operator. For $t$ time-steps of the DTQW, the proposed circuit requires only $O(n^2 + nt)$ two-qubit gates compared to the $O(n^2 t)$ of the current most efficient implementation based on quantum Fourier transforms. We test the proposed circuit on an IBM quantum device for a Hadamard DTQW on the $4$- and $8$-cycle characterized by periodic dynamics and recurrent generation of maximally entangled single-particle states. Experimental results are meaningful well beyond the regime of few time steps, paving the way for reliable implementation and use on quantum computers.

description: The linear properties of the geodesic acoustic modes (GAM) in tokamaks are investigated by means of the comparison of analytical theory and gyrokinetic numerical simulations. The dependence on the value of the safety factor, finite-orbit-width of the ions in relation to the radial mode width, magnetic-flux-surface shaping, and electron/ion mass ratio are considered. Nonuniformities in the plasma profiles (such as density, temperature, or safety factor), electro-magnetic effects, collisions and presence of minority species are neglected. Also, only linear simulations are considered, focusing on the local dynamics. We use three different gyrokinetic codes: the lagrangian (particle-in-cell) code ORB5, the eulerian code GENE and semi-lagrangian code GYSELA. One of the main aims of this paper is to provide a detailed comparison of the numerical results and analytical theory, in the regimes where this is possible. This helps understanding better the behavior of the linear GAM dynamics in these different regimes, the behavior of the codes, which is crucial in the view of a future work where more physics is present, and the regimes of validity of each specific analytical dispersion relation.

description: No abstracts are to be cited without prior reference to the author.In the Baltic Sea upwelling is an important process, especially in the coastal areas, causing vertical mixing and displacement of the water body. During thermal stratification, when the surface layer of the water is depleted of nutrients, upwelling plays a key role in replenishing the euphotic zone with the nutritional components necessary for biological productivity. Up to now, only a few comprehensive investigations have been carried out to study where the main upwelling areas in the Baltic locate and how commonly upwellings take place there. Here, three-dimensional, high-resolution modelling is used as a tool to statistically estimate an index reflecting the persistency of upwellings, in various parts of the Baltic for the summer season during a 10-year period from 1979 to 1988. The new idea in this paper is to define the persistency (stability) of the vertical velocity to represent an upwelling index, instead of calculating an frequency of upwelling on the basis of changes in the sea-surface temperature, as is usually done.

description: Induction machines have been widely used in power generation and other industrial applications for decades due to their numerous advantages like robust design and lower cost as compared to synchronous machines. When a standalone induction generator like in isolated wind farm and micro hydro is driven by a mechanical prime mover, the residual magnetism in the rotor of the machine induces an electro-magnetic field (EMF) in the stator windings at a frequency proportional to the rotor speed. This EMF is applied to the capacitors (cap-bank) connected to the stator terminals and causes reactive current to flow in the stator windings. The capbank provides necessary reactive power to run the generator as well as reactive power to the inductive loads connected to the generator. Multiple generators can be connected in parallel to increase reliability and to provide required power for increasing loads. This paper presents a PSIM simulation model of a self-excited induction generator (SEIG) using the well-known [alpha beta gamma] three axis model for induction machines (IM). Transient response of standalone generator, two SEIG generators connected in parallel, and SEIG connected to grid is also part of this study. This paper is expected to be a learning module for electrical engineering students to understand dynamics of the induction machines.

description: Stellar flares are critical phenomena on stellar surfaces, which are closely tied to stellar magnetism. While extensively studied in main-sequence (MS) stars, their occurrence in evolved compact stars, specifically hot subdwarfs and white dwarfs (WDs), remains scarcely explored. Based on Cycles 1-5 of TESS photometry, we conducted a pioneering survey of flare events in $\sim12,000$ compact stars, corresponding to $\sim38,000$ light curves with 2-minute cadence. Through dedicated techniques for detrending light curves, identifying preliminary flare candidates, and validating them via machine learning, we established a catalog of 1016 flares from 193 compact stars, including 182 from 58 sdB/sdO stars and 834 from 135 WDs, respectively. However, all flaring compact stars showed signs of contamination from nearby objects or companion stars, preventing sole attribution of the detected flares. For WDs, it is highly probable that the flares originated from their cool MS companions. In contrast, the higher luminosities of sdB/sdO stars diminish companion contributions, suggesting that detected flares originated from sdB/sdO stars themselves or through close magnetic interactions with companions. Focusing on a refined sample of 23 flares from 13 sdB/sdO stars, we found their flare frequency distributions were slightly divergent from those of cool MS stars; instead, they resemble those of hot B/A-type MS stars having radiative envelopes. This similarity implies the flares on sdB/sdO stars, if these flares did originate from them, may share underlying mechanisms with hot MS stars, which warrants further investigation.

description: Here we demonstrate a magnetic resonance coupling based wireless triboelectric nanogenerator (TENG) and fully self-powered wireless sensors. By integrating a microswitch and an inductor with the TENG, the pulsed voltage output is converted into a sinusoidal voltage signal with a fixed frequency. This can be transmitted wirelessly from the transmit coil to the resonant-coupled receiver coil with an efficiency of 73% for a 5 cm distance between the two coils (10 cm diameter). Analytic models of the oscillating and coupled voltage signals for the wireless energy transfer are developed, showing excellent agreement with the experimental results. A TENG of 40 × 50 mm2 can wirelessly light up 70 LEDs or charge up a 15 μF capacitor to 12.5 V in ~90 s. The system is further utilized for two types of fully self-powered wireless chipless sensors with no microelectronic components. The technologies demonstrate an innovative strategy for a wireless 'green' power source and sensing.

description: We present here a browser-based application for visualizing patterns of connectivity in 3D stacked data matrices with large numbers of pairwise relations. Visualizing a connectivity matrix, looking for trends and patterns, and dynamically manipulating these values is a challenge for scientists from diverse fields, including neuroscience and genomics. In particular, high-dimensional neural data include those acquired via electroencephalography (EEG), electrocorticography (ECoG), magnetoencephalography (MEG), and functional MRI. Neural connectivity data contains multivariate attributes for each edge between different brain regions, which motivated our lightweight, open source, easy-to-use visualization tool for the exploration of these connectivity matrices to highlight connections of interest. Here we present a client-side, mobile-compatible visualization tool written entirely in HTML5/JavaScript that allows in-browser manipulation of user-defined files for exploration of brain connectivity. Visualizations can highlight different aspects of the data simultaneously across different dimensions. Input files are in JSON format, and custom Python scripts have been written to parse MATLAB or Python data files into JSON-loadable format. We demonstrate the analysis of connectivity data acquired via human ECoG recordings as a domain-specific implementation of our application. We envision applications for this interactive tool in fields seeking to visualize pairwise connectivity.

description: In this paper the advantages of an enhanced boost converter are utilized in a photovoltaic based energy system, in order to improve the efficiency and the output/input voltage gain. In addition, this circuit topology allows lower input current ripple than conventional single-switch DC/DC boost converters, increasing photovoltaic energy yield. The floating interleaved boost converter was modeled, and a linear feedback controller was discretized for use with an embedded microcontroller. This controller consisted of a decoupled dual loop control structure capable of interacting with a maximum power point tracking procedure. Two strategies for controlling the DC link voltage were evaluated and compared in simulation. Moreover, two maximum power point tracking techniques were also implemented and compared; their performances were evaluated by simulation as well as demonstrated by an experimental set-up. The results show that the addressed topology is very promising, with potential benefits for solar power applications.

description: No abstracts are to be cited without prior reference to the author.The water mass on the Faroe Shelf is distinct from the off-shelf water surrounding the shelf. This difference of water masses is reflected in the temperature and salinity distributions. The on-shelf water is colder and fresher than the off-shelf water throughout most of the year. A temperature/salinity front thus forms, where the on-shelf water meets the off-shelf water. The waters inside the front have a different cycle of primary production and support a different ecosystem from the off-shelf waters and they are important nursery areas for larvae of many commercially important fish stocks. Sea surface temperature measurements from the R/V Magnus Heinason in the period February 1999 to November 2000 show the existence of the front throughout the year except for a short period in autumn, and the largest cross-front gradients are found in the spring. Also, the measurements are used to find typical values for the frontal location and width in various directions across the shelf. The observed characteristics of the front are discussed in relation to bottom topography and proximity to a shelf edge, to the heating/cooling cycle driven by the air-sea heat flux, and to various theories for fronts generated by tidal or wind mixing.

description: This abstract describes the published paper that documents a case study of the emergence and expansive adaptation of the ethics education component of the National Nanotechnology Initiative (NNI). The case study began with a brief overview of nanotechnology as a U.S. federal policy initiative and the Nanotechnology Undergraduate Education (NUE) Program. Using nanotechnology as a framework, an interdisciplinary faculty team of more than 20 members at the Colorado School of Mines (CSM) developed the Nano-Science, Technology, Ethics, and Policy (NanoSTEP) project to better understand the effectiveness and influence of ethics and policy learning in the undergraduate engineering curriculum, and to graduate more effective contributors to 21st century engineering practice. NanoSTEP also examined relationships between emerging technologies and underrepresented populations, with respect to the potential for environmental and social justice deficiencies, both in access to opportunities for research and education, and in regard to benefitting from nanotechnology research and design. The NanoSTEP project components include a poster, a presentation, and a two-part curricular module, all of which may be found in the Mines Institutional Repository.

Identifying the stored energy of a hyperelastic structure by using an attenuated Landweber method

description: We consider the nonlinear, inverse problem of identifying the stored energy function of a hyperelastic material from full knowledge of the displacement field as well as from surface sensor measurements. The displacement field is represented as a solution of Cauchy's equation of motion, which is a nonlinear, elastic wave equation. Hyperelasticity means that the first Piola-Kirchhoff stress tensor is given as the gradient of the stored energy function. We assume that a dictionary of suitable functions is available and the aim is to recover the stored energy with respect to this dictionary. The considered inverse problem is of vital interest for the development of structural health monitoring systems which are constructed to detect defects in elastic materials from boundary measurements of the displacement field, since the stored energy encodes the mechanical peroperties of the underlying structure. In this article we develope a numerical solver for both settings using the attenuated Landweber method. We show that the parameter-to-solution map satisfies the local tangential cone condition. This result can be used to prove local convergence of the attenuated Landweber method in case that the full displacement field is measured. In our numerical experiments we demonstrate how to construct an appropriate dictionary and show that our algorithm is well suited to localize damages in various situations.

Subjects: Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.Lagrangian models of dispersal are gaining popularity, yet many are implemented with simple biased random walk schemes. This paper discusses additional techniques for diffusion processes, some of which are new while most are well known in the stochastic literature. We emphasize the relationship between advection-diffusion equations and stochastic differential equations (SDE’s) and we discuss different interpretations of SDE’s. These are the Itˆo and the Stratonovich interpretations, as well as a third Transport interpretation which has not received much attention in the literature, despite some appealing features. We also discuss repeated sim-ulation runs with the same noise sequence, but different parameters. This can save much computational effort in sensitivity studies, and brings at-tention to the strong convergence of the discretisation scheme. This favors higher-order discretisation schemes; as a minimum the Milstein scheme as an alternative to Euler schemes. Finally we discuss simulation backwards in time, i.e. terminal value problems involving SDE’s. We emphasize two different understandings of the problem, and compare with analysis of the backward Kolmogorov equation.

description: This article aims to explain longitudinal and cross-sectional variation in regional government composition – oversized majorities and incongruence between regional and national governments (cross-cutting) – and regional government alternation. The analysis focuses on the explanatory value of a wide range of regional-level institutional variables, such as majoritarian vs. proportional voting systems and established practices of consociationalism. In addition, it provides a tentative exploration of the impact of regional (i.e. non-state-wide) parties on government composition and alternation. The findings show that most institutional variables have the expected impact, e.g., majoritarian voting systems increase government alternation and consensual practices decrease both cross-cutting and alternation. The analysis also suggests that regional parties impact on government composition and alternation in two ways. Strong regional parties increase cross-cutting and, once in office, they tend to reduce alternation. Smaller regional parties out of office tend to increase alternation and to decrease oversized government as their seat shares grow.

description: The well-being and productivity of cattle are closely linked to cattle health. Moreover, disease is costly. In 2005, the estimated cost of cattle death due to all disease was $2 billion;5 this does not include the costs of treatment or production loss due to disease. Preservation of cattle health requires that veterinarians understand the causes of disease and the methods to prevent disease. Because animal production systems and infectious agents are always evolving, new causes of disease are always developing. Thus, ongoing research is necessary to determine the causes of new and emerging diseases, to determine the true impact of disease on well-being and productivity, and to develop evidence-based methods to treat and prevent disease.

description: We propose a systematic approach to obtain various forms of insulating titanium oxynitrides Ti$_{n}$N$_{2}$O$_{2n-3}$ and we conduct a detailed study on its $n=2$ case, Ti$_{2}$N$_{2}$O. We study the energetics and the electronic structures of Ti$_{2}$N$_{2}$O and compare these results with those of pristine and nitrogen-doped TiO$_{2}$ within the framework of the density-functional theory (DFT) and the GW approximation. We find that Ti$_{2}$N$_{2}$O is semiconducting with the calculated band-gap of 1.81 eV, which is significantly smaller than those of pristine TiO$_{2}$ rutile (3.14 eV) or anatase (3.55 eV). Furthermore, the reduction of the band-gap of Ti$_{2}$N$_{2}$O is realized not by lowering of the conduction-band minimum but by rising the valence-band maximum. Therefore the proposed Ti$_{2}$N$_{2}$O has suitable band-edge alignment for water-splitting photocatalysis. Finally, total energy calculations indicate that Ti$_{2}$N$_{2}$O is potentially easier to synthesize than nitrogen-doped TiO$_{2}$. Based on these results, we propose Ti$_{2}$N$_{2}$O as a promising visible-light photocatalytic material.

description:  

The livestock sector in Jammu and Kashmir is a crucial component of its agricultural economy and makes a greater contribution to the state's gross domestic product than it does to the country as a whole. "In J&K, the livestock sector provides 5.04 percent of the state's GDP, compared to a national average of 4.1 percent for livestock. A robust 33 percent of the state's agricultural GDP is contributed by the livestock sector. 1.79 percent of the 512 million livestock in the nation dwell in J&K." J&K has significantly more animals per person than the national average. J&K is home to 77.14 percent of the nation's yaks, 20 percent of its horses, and 5.2 percent of its sheep. As per the Economic Survey-2021, the contribution of Livestock in total agriculture and allied sector Gross Value Added (at Constant Prices) has increased from 24.32% (2014-15) to 28.63% (2018-19). Livestock income has become an important secondary source of income for rural families and has assumed an important role in achieving the goal of doubling farmers’ income. Nearly 80 per cent of the J-K population lives in rural areas and about 60per cent of the revenue is generated by the agriculture and animal husbandry sector.

description: In this paper, we propose beamforming schemes to simultaneously transmit data securely to multiple information receivers (IRs) while transferring power wirelessly to multiple energy-harvesting receivers (ERs). Taking into account the imperfection of the instantaneous channel state information (CSI), we introduce a chance-constrained optimization problem to minimize the total transmit power while guaranteeing data transmission reliability, data transmission security, and power transfer reliability. As the proposed optimization problem is non-convex due to the chance constraints, we propose two robust reformulations of the original problem based on safe-convex-approximation techniques. Subsequently, applying semidefinite programming relaxation (SDR), the derived robust reformulations can be effectively solved by standard convex optimization packages. We show that the adopted SDR is tight and thus the globally optimal solutions of the reformulated problems can be recovered. Simulation results confirm the superiority of the proposed methods in guaranteeing transmission security compared to a baseline scheme. Furthermore, the performance of proposed methods can closely follow that of a benchmark scheme where perfect CSI is available for resource allocation.

Additionally we present first crossing distributions derived by simulating paths from fractional Brownian motion. We compare the results of the analytical solutions with both those of simulations and those of some approximated solutions which have been used in the literature. Finally, we present multiplicity functions for dark matter structures resulting from our analytical approach and we compare with those resulting from N-body simulations. We show that the results of analytical solutions are in good agreement with those of path simulations but differ significantly from those derived from approximated solutions. Additionally, multiplicity functions derived from fractional Brownian motion are poor fits of the those which result from N-body simulations. We also present comparisons with other models which exist in the literature and we discuss different ways of improving the agreement between analytical results and N-body simulations.

description: This recipe is designed for an introduction to design course and is most suited to courses with a team project. It can be used to support courses in disciplines across STEM, especially environmental science, mechanical engineering, sustainability studies, and civil engineering. It can also be effectively deployed in courses in which students engage with stakeholders or customers of some sort. Librarians can use the lesson to help students tease out the contextual nature of authority and the role of stakeholder input plays in good design.

description: Bovine respiratory diseases (BRD) occurring in the feedlot represent the major disease entity during the feeding period. Several bacteria, viruses, and Mycoplasma spp are reported as causative agents. Feedlot BRD may occur at various times, although the early disease appearing after arrival and processing often receives the most attention. The diagnostician and clinician are faced with several clinical presentations and agents/lesions in the fatal cases. The purpose of this study was to chart the fatal pneumonia cases over a one-year period in one Oklahoma feedyard, recording agent identification, observed pathology and animal treatment information. These cattle died either in the sick pen or suddenly in regular feeding pens without treatment. A clinical diagnosis of BRD was assigned to all cases charted. Samples of lung collected at necropsy (fresh and formalin fixed) were submitted for agent identification and histopathology. In the later stages of the study, skin samples were tested for BVDV by immunohistochemistry (IHC).

description: The edit distance under the DCJ model can be computed in linear time for genomes with equal content or with Indels. But it becomes NP-Hard in the presence of duplications, a problem largely unsolved especially when Indels are considered. In this paper, we compare two mainstream methods to deal with duplications and associate them with Indels: one by deletion, namely DCJ-Indel-Exemplar distance; versus the other by gene matching, namely DCJ-Indel-Matching distance. We design branch-and-bound algorithms with set of optimization methods to compute exact distances for both. Furthermore, median problems are discussed in alignment with both of these distance methods, which are to find a median genome that minimizes distances between itself and three given genomes. Lin-Kernighan (LK) heuristic is leveraged and powered up by sub-graph decomposition and search space reduction technologies to handle median computation. A wide range of experiments are conducted on synthetic data sets and real data sets to show pros and cons of these two distance metrics per se, as well as putting them in the median computation scenario.

description: Power generation in Germany is currently transitioning from a system based on large, central, thermal power plants to one that heavily relies on small, decentral, mostly renewable power generators. This development poses the question how transmission grids' reactive power demand for voltage management, covered by central power plants today, can be supplied in the future. In this work, we estimate the future technical potential of such an approach for the whole of Germany. For a 100% renewable electricity scenario we set the possible reactive power supply in comparison with the reactive power requirements that are needed to realize the simulated future transmission grid power flows. Since an exact calculation of distribution grids' reactive power potential is difficult due to the unavailability of detailed grid models on such scale, we optimistically estimate the potential by assuming a scaled, averaged distribution grid model connected to each of the transmission grid nodes. We find that for all except a few transmission grid nodes, the required reactive power can be fully supplied from the modeled distribution grids. This implies that - even if our estimate is overly optimistic - distributed reactive power provisioning will be a technical solution for many future reactive power challenges.
title: Azithromycin mass drug administration for reducing child mortality in Malawi.

description: BACKGROUND: Child mortality has decreased considerably in recent years but more than one in ten children still die before their fifth birthday in several African countries. The MORDOR study investigated whether azithromycin mass drug administration (MDA) reduces child mortality in three countries in Africa. The study described within this thesis was conducted at the MORDOR-Malawi site and aims to provide additional detail on potential mechanisms of effect of the intervention; macrolide resistance; and cost-effectiveness. METHODS: The study involved cluster randomisation of communities in Mangochi District, Malawi, to biannual azithromycin or placebo MDA. Household visits were conducted to update the census and perform verbal autopsies (VAs) to assess causes of death. Indicators related to healthcare access; malaria risk; and water, sanitation and hygiene were measured. Nasopharyngeal samples were collected to assess macrolide resistance. Cost data were collected for one complete round of fieldwork. RESULTS: The study included 334 clusters. The mortality rate ratio in azithromycin-treated compared to placebo-treated communities was 0.91 (95%CI: 0.79–1.05); P=0.20. There was evidence for an effect of the intervention in infants aged 1-5 months: 0.70 (95%CI: 0.50-0.99); P=0.04; but not in older age groups. The VA analyses suggested possible effects on pneumonia, HIV/AIDS and diarrhoea mortality. The intervention was highly cost-effective according to the WHO’s willingness-to-pay thresholds, costing $898 per death averted. At the 12-month and 24-month follow-up rounds, macrolide resistance in Streptococcus pneumoniae was higher in the azithromycin group compared to placebo. CONCLUSION: The mortality findings at the MORDOR-Malawi site could be explained by the broad spectrum of activity of azithromycin against gut and respiratory organisms, including non-vaccine pneumococcal serotypes and other aetiological causes of pneumonia, sepsis and meningitis. Azithromycin MDA is a feasible short-term intervention to reduce child mortality, whilst longer term sustainable health system improvements are pursued. Vigilance of antibiotic resistance is required.

description: No abstracts are to be cited without prior reference to the author.Historically, cod and haddock spawning has been split between eastern and western Georges Bank. Cod especially can spawn predominantly on the Northeast Peak (NEP) or western Georges Bank (WGB). Variable spawning within a bank system can have different consequences for transport of eggs and larvae and subsequent growth and survival to recruitment. The MARMAP 11-year time series (1977-87) of cod and haddock egg/larval distributions was used as a basis for this comparative analysis. For each year, 1978-87, weekly mean flow fields were based on linear interpolation of seasonal velocity fields with wind and upstream boundary forcing anomalies. Particles were released from historical spawning areas using various scenarios (release region and vertical distribution at 4 and 8 weeks) to assess the relative retention of larvae within the 70-m isobath.

description: Tail injuries commonly occur in feedlot cattle that are housed in barns with slatted floors, facilities that are commonly found in the Great Lakes Region. These injuries put cattle at risk of developing secondary complications such as tail infections, ascending myelitis, and paresis. The practice of docking the tails of cattle upon entry into these feedlot facilities was initiated to prevent tail injuries. According to a recent survey, approximately two-thirds of Michigan feedlots dock the tails of cattle at entry. Tail docking raises potential welfare concerns because it is painful and removes an important method of fly avoidance. The purpose of this study was to describe the behavioral response of cattle following tail docking.

description: We investigate the combinatorial and dynamical properties of so-called nearly Euclidean Thurston maps, or NET maps. These maps are perturbations of many-to-one folding maps of an affine two-sphere to itself. The close relationship between NET maps and affine maps makes computation of many invariants tractable. In addition to this, NET maps are quite diverse, exhibiting many different behaviors. We discuss data, findings, and new phenomena.
