description: In this paper we examine the interaction of \bar B N, \bar B Δ, \bar B^* N and \bar B^* Δstates, together with their coupled channels, using a mapping from the light meson sector. The assumption that the heavy quarks act as spectators at the quark level automatically leads us to the results of the heavy quark spin symmetry for pion exchange and reproduces the results of the Weinberg Tomozawa term, coming from light vector exchanges in the extended local hidden gauge approach. With this dynamics we look for states dynamically generated from the interaction and find two states with nearly zero width, which we associate to the Λ_b(5912) and Λ_b(5920) states. The states couple mostly to \bar B^* N, which are degenerate with the Weinberg Tomozawa interaction. The difference of masses between these two states, with J=1/2, 3/2 respectively, is due to pion exchange connecting these states to intermediate \bar B N states. In addition to these two Λ_b states, we find three more states with I=0, one of them nearly degenerate in two states of J=1/2,3/2. Furthermore we also find eight more states in $I=1$, two of them degenerate in J=1/2, 3/2, and other two degenerate in J=1/2, 3/2, 5/2.

description: We demonstrate fully demixed (separated) robust and stable bright binary dipolar Bose-Einstein condensate soliton in a quasi-one-dimensional setting formed due to dipolar interactions for repulsive contact interactions. For large repulsive interspecies contact interaction the first species may spatially separate from the second species thus forming a demixed configuration, which can be spatially-symmetric or symmetry-broken. In the spatially-symmetric case, one of the the species occupies the central region, whereas the other species separates into two equal parts and stay predominantly out of this central region. In the symmetry-broken case, the two species stay side by side. Stability phase diagrams for the binary solitons are obtained. The results are illustrated with realistic values of parameters in the binary 164Dy-168Er and 164Dy-162Dy mixtures. The demixed solitons are really soliton molecules formed of two types of atoms. A proposal for creating dipolar solitons in experiments is also presented.

description: Background: Mild stroke affects more than half the stroke population, yet there is limited evidence characterizing cognition over time in this population, especially with predictive approaches applicable at the individual-level. We aimed to identify patterns of recovery and the best combination of demographic, clinical, and lifestyle factors predicting individual-level cognitive state at 3- and 12-months after mild stroke. Methods: In this prospective cohort study, the Montreal Cognitive Assessment (MoCA) was administered at 3–7 days, 3- and 12-months post-stroke. Raw changes in MoCA and impairment rates (defined as MoCA<24 points) were compared between assessment time-points. Trajectory clusters were identified using variations of ≥1 point in MoCA scores. To further compare clusters, additional assessments administered at 3- and 12-months were included. Gamma and Quantile mixed-effects regression were used to predict individual MoCA scores over time, using baseline clinical and demographic variables. Model predictions were fitted for each stroke survivor and evaluated using model cross-validation to identify the overall best predictors of cognitive recovery. Results: Participants’ (n = 119) MoCA scores improved from baseline to 3-months (p<0.001); and decreased from 3- to 12-months post-stroke (p = 0.010). Cognitive impairment rates decreased significantly from baseline to 3-months (p<0.001), but not between 3- and 12-months (p = 0.168). Nine distinct trajectory clusters were identified. Clinical characteristics between clusters at each time-point varied in cognitive outcomes but not in clinical and/or activity participation outcomes. Cognitive performance at 3- and 12-months was best predicted by younger age, higher physical activity levels, and left-hemisphere lesion side. Conclusion: More than half of mild-stroke survivors are at risk of cognitive decline one year after stroke, even when preceded by a significantly improving pattern in the first 3-months of recovery. Physical activity was the only modifiable factor independently associated with cognitive recovery. Individual-level prediction methods may inform the timing and personalized application of future interventions to maximize cognitive recovery post-stroke.

description: Planned instruments utilising multi-object adaptive optics systems on the forthcoming extremely large telescopes require large numbers of high order deformable mirrors. These devices are a significant cost driver, particularly if specifications regarding the number of faulty actuators are stringent. Here, we investigate the effect on adaptive optics performance that such faulty actuators have, and draw conclusions about how far faulty actuator specifications (and hence cost) can be relaxed without having a significant effect on adaptive optics performance. We also provide performance estimates using a map of faulty actuators from an existing deformable mirror. We investigate the effect of faulty actuators using an end-to-end Monte Carlo adaptive optics simulation code. We find that for actuators stuck at a fixed height above the deformable mirror surface, between $1--2\%$ of actuators can be faulty before significant performance degradation occurs. For actuators that a coupled to nearest neighbours, up to about $5\%$, can be faulty before \ao performance begins to be affected.

description: The objective of this study was to determine the optimal irrigation needs of six popular Egyptian bread wheat (Triticum aestivum L.) cultivars and to establish baseline effect of reduced irrigation on yield. The varieties included were Sids1, Sids14, Sakha94, Sakha95, Gemmiza12, and Shandawee1. The experiment was conducted at two different locations, Nubaria and Sids Agricultural Research Stations, Egypt over two consecutive seasons, 2020–2021 and 2021–2022. There was a reduction in yield with the decrease in the number of irrigations. However, several cultivars performed better for yield and other traits with one less irrigation than the current irrigation practices in the region. Therefore, the study may help revise irrigation recommendations. Overall, the cultivars Sakha95, Sids1, and Sids14 were taller and had more kernels per spike, higher seed index, and greater grain yield under reduced irrigations and showed the best drought tolerance index. The tested bread wheat cultivars were genotyped using Inter-Retrotransposon Amplified Polymorphism (IRAP) and Start Codon Targeted (SCoT) markers which showed relation among the cultivars. Among the two types of markers, IRAP was better than SCoT markers for reliability and robustness. Among the six cultivars, 58% of the IRAP markers detected polymorphism as compared to 38% with SCoT markers. The two wheat cultivars Sids1 and Sids14, which performed better for important agronomic traits under water stress conditions, could be used as donors for the national wheat breeding program for drought tolerance.

description: We propose a cognitively and linguistically motivated set of sorts for lexical semantics in a compositional setting: the classifiers in languages that do have such pronouns. These sorts are needed to include lexical considerations in a semantical analyser such as Boxer or Grail. Indeed, all proposed lexical extensions of usual Montague semantics to model restriction of selection, felicitous and infelicitous copredication require a rich and refined type system whose base types are the lexical sorts, the basis of the many-sorted logic in which semantical representations of sentences are stated. However, none of those approaches define precisely the actual base types or sorts to be used in the lexicon. In this article, we shall discuss some of the options commonly adopted by researchers in formal lexical semantics, and defend the view that classifiers in the languages which have such pronouns are an appealing solution, both linguistically and cognitively motivated.

description: We explore the impact of obliquity variations on planetary habitability in hypothetical systems with high mutual inclination. We show that large amplitude, high frequency obliquity oscillations on Earth-like exoplanets can suppress the ice-albedo feedback, increasing the outer edge of the habitable zone. We restrict our exploration to hypothetical systems consisting of a solar-mass star, an Earth-mass planet at 1 AU, and 1 or 2 larger planets. We verify that these systems are stable for $10^8$ years with N-body simulations, and calculate the obliquity variations induced by the orbital evolution of the Earth-mass planet and a torque from the host star. We run a simplified energy balance model on the terrestrial planet to assess surface temperature and ice coverage on the planet's surface, and we calculate differences in the outer edge of the habitable zone for planets with rapid obliquity variations. For each hypothetical system, we calculate the outer edge of habitability for two conditions: 1) the full evolution of the planetary spin and orbit, and 2) the eccentricity and obliquity fixed at their average values. We recover previous results that higher values of fixed obliquity and eccentricity expand the habitable zone, but also find that obliquity oscillations further expand habitable orbits in all cases. Terrestrial planets near the outer edge of the habitable zone may be more likely to support life in systems that induce rapid obliquity oscillations as opposed to fixed-spin planets. Such planets may be the easiest to directly characterize with space-borne telescopes.

title: Urogenital tuberculosis as a part of extrapulmonary tuberculosis in two epidemic regions
Creators: name: Kulchavenya, Ekaterina

Year: 2020

description: Introduction: The role of extrapulmonary tuberculosis (EPTB) in general and urogenital tuberculosis (UGTB) in particular is under-estimated in official statistics, medical practice and by the population.

The purpose of this report was to estimate the relative importance of UGTB in the spectrum of EPTB in two epidemic regions of central Asia (Siberia, Russian Federation, and the Republic of Tajikistan) and its relation to human immunodeficiency virus (HIV) comorbidity, age and sex.

Material and Methods: A retrospective descriptive report based on official statistics from the tuberculosis dispensaries (special outpatient clinics) of Siberia and Tajikistan for 2018 was made.

Results: In Siberia the most common form was bone and joint tuberculosis (BJTB) – 43.6%, followed by urogenital tuberculosis (UGTB) – 21.3%, and tuberculosis of the central nervous system (CNS-TB) – 17.0%. In Tajikistan the leading localization was also BJTB (46.0%), followed by tuberculosis of peripheral lymph nodes (LNTB) – 27.7%, whereas the percentage of UGTB was only 6.1%. Patients combining EPTB and HIV infection were 36.8% in Siberia but only 3.5% in Tajikistan. CNS-TB was the predominating localization in patients with HIV infection in Siberia (38.3%), while in Tajikistan LNTB and BJTB (37.9% and 31.0%, respectively) were the most common sites. UGTB was the rarest form among HIV-infected patients reported in both regions.

In Siberia CNS-TB was detected twice as often in men than in women (67.9% versus 32.1%) and a similar proportion was described for BJTB (62.9% versus 37.1% ). In Tajikistan female patients predominated among CNS-TB (71.4%), LNTB (81.5%), and abdominal tuberculosis (68.9%). UGTB equally often affected men and women in both regions.

Conclusions: HIV-comorbidity significantly changes the spectrum of EPTB. UGTB had a negative correlation with HIV infection. Spectrum of EPTB is variable from region to region. The different sex-age relationships with EPTB in the two regions cannot be explained.

description: The upper critical field of NaFe$_{1-x}$Co$_x$As was measured from $x=0$ to $x=0.08$, with the magnetic field applied parallel ($H_{\rm c2}^\parallel$) and normal ($H_{\rm c2}^\perp$) to the planes. The data were fitted using one-band and two-band models. The orbital and paramagnetic components of the upper critical field were extracted for $H_{\rm c2}^\parallel$, which we find to to be strongly dominated by paramagnetic pair-breaking. In the parent compound the paramagnetic limit is equal to the value expected by BCS theory. However, substitution of Fe by Co leads to an enhancement above the BCS limit by a factor of approximately 1.6. In the over-doped region, we observe a significant convex curvature in $H_{\rm c2}^\perp$ at low temperatures, which we attribute to the two-band nature of the superconductivity and the asymmetry between the two bands. Additionally, we discuss the behavior of critical field anisotropy, coherence length $ξ$, and the penetration depth $λ$.

description: We investigate the formation of fingered flow in dry granular media under simulated rainfall using a quasi-2D experimental set-up composed of a random close packing of mono-disperse glass beads. Using controlled experiments, we analyze the finger instabilities that develop from the wetting front as a function of fundamental granular (particle size) and fluid properties (rainfall, viscosity).These finger instabilities act as precursors for water channels, which serve as outlets for water drainage. We look into the characteristics of the homogeneous wetting front and channel size as well as estimate relevant time scales involved in the instability formation and the velocity of the channel finger tip. We compare our experimental results with that of the well-known prediction developed by Parlange and Hill [1976]. This model is based on linear stability analysis of the growth of perturbations arising at the interface between two immiscible fluids. Results show that in terms of morphology, experiments agree with the proposed model. However, in terms of kinetics we nevertheless account for another term that describes the homogenization of the wetting front. This result shows that the manner we introduce the fluid to a porous medium can also influence the formation of finger instabilities.

description: Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and diffusion of cosmic rays. Despite its importance, interstellar turbulence, alike turbulence in general, is far from being fully understood. In this review we present the basics of turbulence physics, focusing on the statistics of its structure and energy cascade. We explore the physics of compressible and incompressible turbulent flows, as well as magnetized cases. The most relevant observational techniques that provide quantitative insights of interstellar turbulence are also presented. We also discuss the main difficulties in developing a three-dimensional view of interstellar turbulence from these observations. Finally, we briefly present what could be the the main sources of turbulence in the interstellar medium.

description: The realization of an all-optical transistor where one 'gate' photon controls a 'source' light beam, is a long-standing goal in optics. By stopping a light pulse in an atomic ensemble contained inside an optical resonator, we realize a device in which one stored gate photon controls the resonator transmission of subsequently applied source photons. A weak gate pulse induces bimodal transmission distribution, corresponding to zero and one gate photons. One stored gate photon produces fivefold source attenuation, and can be retrieved from the atomic ensemble after switching more than one source photon. Without retrieval, one stored gate photon can switch several hundred source photons. With improved storage and retrieval efficiency, our work may enable various new applications, including photonic quantum gates, and deterministic multiphoton entanglement.

description: This paper proposes to perform authorship analysis using the Fast Compression Distance (FCD), a similarity measure based on compression with dictionaries directly extracted from the written texts. The FCD computes a similarity between two documents through an effective binary search on the intersection set between the two related dictionaries. In the reported experiments the proposed method is applied to documents which are heterogeneous in style, written in five different languages and coming from different historical periods. Results are comparable to the state of the art and outperform traditional compression-based methods.

Two examples are presented. In the first, we illustrate how to realize the Hadamard gate in a single-qubit system, while in the second, the controlled-NOT (CNOT) gate is implemented in two-qubit systems with the Ising and Heisenberg interactions. Furthermore, we demonstrate that the control can drive the time-evolution operator into the local equivalence class of the CNOT gate and the operator keeps in this class forever with the existence of Ising coupling.

description: A growing body of work aims at designing and testing micron-scale synthetic swimmers. One method, inspired by the locomotion of flagellated bacteria, consists of applying a rotating magnetic field to a rigid, helically-shaped, propeller attached to a magnetic head. When the resulting device, termed an artificial bacteria flagellum, is aligned perpendicularly to the applied field, the helix rotates and the swimmer moves forward. Experimental investigation of artificial bacteria flagella shows that at low frequency of the applied field, the axis of the helix does not align perpendicularly to the field but wobbles around the helix, with an angle increasing as the inverse of the field frequency. By numerical computations and asymptotic analysis, we provide a theoretical explanation for this wobbling behavior. We numerically demonstrate the wobbling-to-swimming transition as a function of the helix geometry and the dimensionless Mason number which quantifies the ratio of viscous to magnetic torques. We then employ an asymptotic expansion for near-straight helices to derive an analytical estimate for the wobbling angle allowing to rationalize our computations and past experimental results. These results can help guide future design of artificial helical swimmers.
Models of cuspy triaxial stellar systems. III: The effect of velocity anisotropy on chaoticity

description: In several previous investigations we presented models of triaxial stellar systems, both cuspy and non cuspy, that were highly stable and harboured large fractions of chaotic orbits. All our models had been obtained through cold collapses of initially spherical $N$--body systems, a method that necessarily results in models with strongly radial velocity distributions. Here we investigate a different method that was reported to yield cuspy triaxial models with virtually no chaos. We show that such result was probably due to the use of an inadequate chaos detection technique and that, in fact, models with significant fractions of chaotic orbits result also from that method. Besides, starting with one of the models from the first paper in this series, we obtained three different models by rendering its velocity distribution much less radially biased (i.e., more isotropic) and by modifying its axial ratios through adiabatic compression. All three models yielded much higher fractions of regular orbits than most of those from our previous work. We conclude that it is possible to obtain stable cuspy triaxial models of stellar systems whose velocity distribution is more isotropic than that of the models obtained from cold collapses. Those models still harbour large fractions of chaotic orbits and, although it is difficult to compare the results from different models, we can tentatively conclude that chaoticity is reduced by velocity isotropy.

description: The growth and development of institutions day by day especially universities are increasing very large number of peoples including employees as well as students, working on different domain in distance between multiple integrated institutes, and degrading the overall efficiency of system that cannot facilitate better interoperability and automated integration. In many universities, exist system does not have yet set of connections, in spite of the fact they have different systems running on different platforms in different administrative units or departments. University of Sindh (UoS) is the one of them. In this paper we discuss about Integration of Inter-Connectivity of Information System (i3) in the UoS which is based on Service Oriented Architecture with web services. The proposed system (i3) can monitor and exchange students information in support of verification along heterogeneous and decentralized nature, and provide capability of interoperability in the place of already deployed system in the UoS using different Languages as well as Databases.

description: Le genre Abies est composé d’environ 50 espèces dont l’origine est principalement les zones tempérées de l’hémisphère Nord (http://www.discoverlife.org). Ces espèces y jouent un rôle écologique majeur. Par ailleurs, certaines sont importantes pour la production de bois en dehors de leur aire de répartition naturelle.  D’autres espèces sont très appréciées comme plantes ornementales dans les plantations paysagères. De plus, en raison de leur forme conique naturelle, de leur couleur et de la solidité de leurs branches capables de porter des objets décoratifs, les sapins sont parfaitement adaptés pour une utilisation comme arbre de Noël, notamment les espèces qui conservent longtemps leurs aiguilles après récolte. En Europe, l’espèce communément cultivée comme arbre de Noël est le sapin de Nordmann, alors qu’aux Etats-Unis, le sapin de Fraser (Abies fraseri) et le sapin noble (A. procera) prédominent.  Les autres espèces d’Abies commercialisées comme arbre de Noël sont le sapin baumier (A. balsamea), le sapin géant ou de Vancouver (A. grandis), le sapin de Corée (A. koreana), le sapin de Sibérie (A. sibirica), le sapin subalpin ou des Rocheuses (A. lasiocarpa), le sapin de Turquie (A. bornmuelleriana) et le sapin du Colorado (A. concolor). Le sapin noble est la principale espèce pour la production de branches à la fois en Europe et aux Etats-Unis.

description: Hole doped cuprates show a superconducting critical temperature $T_c$ which follows an universal dome-shaped behavior as function of doping. It is believed that the origin of superconductivity in cuprates is entangled with the physics of the pseudogap phase. An open discussion is whether the source of superconductivity is the same that causes the pseudogap properties. The $t$-$J$ model treated in large-N expansion shows $d$-wave superconductivity triggered by non-retarded interactions, and an instability of the paramagnetic state to a flux phase or $d$-wave charge density wave ($d$-CDW) state. In this paper we show that self-energy effects near $d$-CDW instability may lead to a dome-shaped behavior of $T_c$. In addition, it is also shown that these self-energy contributions may describe several properties observed in the pseudogap phase. In this picture, although fluctuations responsible for the pseudogap properties leads to a dome-shaped behavior, they are not involved in pairing which is mainly non-retarded.

description: Constraints on the mass distribution in high-redshift clusters of galaxies are not currently very strong. We aim to constrain the mass profile, M(r), and dynamical status of the $z \sim 0.8$ LCDCS 0504 cluster of galaxies characterized by prominent giant gravitational arcs near its center. Our analysis is based on deep X-ray, optical, and infrared imaging, as well as optical spectroscopy. We model the mass distribution of the cluster with three different mass density profiles, whose parameters are constrained by the strong lensing features of the inner cluster region, by the X-ray emission from the intra-cluster medium, and by the kinematics of 71 cluster members. We obtain consistent M(r) determinations from three methods (dispersion-kurtosis, caustics and MAMPOSSt), out to the cluster virial radius and beyond. The mass profile inferred by the strong lensing analysis in the central cluster region is slightly above, but still consistent with, the kinematics estimate. On the other hand, the X-ray based M(r) is significantly below both the kinematics and strong lensing estimates. Theoretical predictions from $Λ$CDM cosmology for the concentration--mass relation are in agreement with our observational results, when taking into account the uncertainties in both the observational and theoretical estimates. There appears to be a central deficit in the intra-cluster gas mass fraction compared to nearby clusters. Despite the relaxed appearance of this cluster, the determinations of its mass profile by different probes show substantial discrepancies, the origin of which remains to be determined. The extension of a similar dynamical analysis to other clusters of the DAFT/FADA survey will allow to shed light on the possible systematics that affect the determination of mass profiles of high-z clusters, possibly related to our incomplete understanding of intracluster baryon physics.

description: We report four trigonometric parallaxes for high-mass star-forming regions within 4 kpc of the Galactic center. These measurements were made with the VLBA as part of the BeSSeL Survey. By associating these sources kinematically with large-scale features in CO and HI longitude-velocity diagrams, we begin to outline some major features of the inner Milky Way: the Connecting arm, the near and far 3 kpc arms, and the Norma arm. The Connecting arm in the first Galactic quadrant lies closer to the Galactic center than the far 3 kpc arm and is offset by the long-bar's major axis near its leading edge, supporting the presence of an inner Lindblad resonance. Assuming the 3 kpc arms are a continuous physical structure, the relative Galactocentric distance of its near and far sides suggests highly elliptical streamlines of gas around the bar(s) and a bar corotation radius, r_CR > 3.6 kpc. At a Galactic longitude near 10° and a heliocentric distance of about 5 kpc, the near 3 kpc arm and the Norma arm intersect on a face-on view of our Galaxy, while passing at different Galactic latitudes. We provide an accurate distance measurement to the W31 star-forming complex of 4.95 (+0.5;-0.43) kpc from the Sun, which associates it with a bright CO feature belonging to the near 3 kpc arm.

Data from: What drives diversification? Range expansion tops climate, life history, habitat, and size in lizards and snakes

description: Aim: A major challenge in ecology and evolutionary biology is to explain the dramatic differences in species richness among clades. Much variation in richness is explained by differences in diversification rates among clades, and variation in diversification rates is often linked to various traits. But what types of traits are most important for explaining diversification? Here, we compared the impacts of different types of traits on diversification rates among lizard and snake families, and tested predictions about the relative importance of ecology vs. morphology, static vs. dynamic traits, and alpha vs. beta niche traits. Location: Global. Time period: Recent to ~200 million years ago. Major taxa studied: Squamata. Methods: We compared the relative impacts of traits related to biogeography (range size, range expansion), climate, life history (viviparity), microhabitat, and morphology (body-size) on diversification rates among all 72 family-level clades of squamates. We compiled data on traits, and tested for relationships between traits and diversification rates using phylogenetic multiple regression models. Results: The best-fitting model explained ~60% of the variation in diversification rates across squamate families. This model included only microhabitat (proportion of arboreal species) and a novel, dynamic, ecological/biogeographic beta-niche trait (rate of range expansion), which explained most variance. Other variables had more variable or non-significant contributions, including rates of climatic-niche change. Rates of range expansion were related to species richness, larger body size, and faster rates of climatic-niche change. Main conclusions: Overall, we provide possibly the most comprehensive comparison of the types of traits that can drive diversification. We also help explain diversity patterns in one of the largest vertebrate clades. We show that the rate of range expansion is the most important variable for explaining diversification rates and richness patterns in squamates. We also identify traits that help explain variation in rates of range expansion among clades.
Two thirds of patients may not need routine 12-month specialist review in an epilepsy clinic: A cross-sectional study of clinic appointments

description: Objectives: Timely access to specialist outpatient clinics can be difficult to achieve as outpatient services are often oversubscribed leading to unacceptable wait times. New patients, or those with emergent issues may wait for appointments whilst existing patients are booked in for routine reviews “just in case” there is a problem, using considerable clinic resources. We investigated routine 12-month review appointments to assess whether these appointments changed patient management. Methods: The medical records of 100 randomly selected adult patients attending annual review appointments over 12 months at a publicly-funded specialist outpatient epilepsy clinic in Melbourne, Australia were audited. Demographic and clinical data as well as information about the content of each appointment were analysed to determine whether the appointment resulted in changes to epilepsy management (eg medication change), administrative actions (eg drivers license approval) or the provision of information or education. Logistic regression was performed to assess what clinical factors were associated with changes in patient care arising from the 12-month review appointment. Results: Almost half (47%) of appointments resulted in no change to patient care and 37% had only administrative outcomes, such as the completion of a regulatory driving report. Only 16% of appointments resulted in a change in medical management. The only factor that independently predicted a change in medical management was the occurrence of a seizure in the previous year. The only factor independently associated with not having any change in medical management or administrative action was having an unknown seizure type. Conclusions/ significance: Only a small number of patients experience a change in medical management when attending a 12-month epilepsy clinic appointment, with a need for management change associated with the presence of ongoing seizure. Outpatient services should limit the use of routine annual follow up to those patients most likely to need intervention or support, creating “just in time” capacity for timely access to review as issues arise.

description: Due to the broadcast nature of radio propagation, the wireless transmission can be readily overheard by unauthorized users for interception purposes and is thus highly vulnerable to eavesdropping attacks. To this end, physical-layer security is emerging as a promising paradigm to protect the wireless communications against eavesdropping attacks by exploiting the physical characteristics of wireless channels. This article is focused on the investigation of diversity techniques to improve the physical-layer security, differing from the conventional artificial noise generation and beamforming techniques which typically consume additional power for generating artificial noise and exhibit high implementation complexity for beamformer design. We present several diversity approaches to improve the wireless physical-layer security, including the multiple-input multiple-output (MIMO), multiuser diversity, and cooperative diversity. To illustrate the security improvement through diversity, we propose a case study of exploiting cooperative relays to assist the signal transmission from source to destination while defending against eavesdropping attacks. We evaluate the security performance of cooperative relay transmission in Rayleigh fading environments in terms of secrecy capacity and intercept probability. It is shown that as the number of relays increases, the secrecy capacity and intercept probability of the cooperative relay transmission both improve significantly, implying the advantage of exploiting cooperative diversity to improve the physical-layer security against eavesdropping attacks.

title: Game Changing Education: Empowering High School Stem Teachers to Teach Engineering Using Games

description: In response to the Next Generation Science Standards (NGSS) released in 2013, there was a nationwide push for K-12 schools to include engineering concepts in science classrooms. However, there is an overall lack of teacher preparedness and training towards engineering topics as shown by common engineering misconceptions. To improve this issue, I initiated a qualitative study to describe the strategies and attitudes of high school science, technology, engineering, and mathematics (STEM) teachers that have implemented game-based, engineering activities into their classroom. Game-based learning is an instructional framework that utilizes game-like elements in a classroom and was used in this study because the practice helps students develop the problem solving skills required in engineering disciplines while increasing motivation. I collaborated with and supported four Utah, high school STEM teachers on implementing game-based learning strategies into their classroom to teach engineering components of the NGSS. I collected data in the form of interviews, observations, and lesson plans to analyze common themes that describe strategies and attitudes towards using game-based learning to teach engineering.
I developed three themes to understand the background experiences with engineering, teaching practices, and outcomes based on the teacher’s experience. This work resulted in developing emergent connections to how teachers view themselves and connections between game-based learning classroom strategies and engineering design process elements. Strategies observed such as feedback, classroom competition, team collaborations, were used to help with understanding in the problem definition and optimization portion of the engineering design process. This work contributes to understanding strategies and attitudes towards engineering and computer science that teachers use to teach to the new NGSS standards that involve developing and implementing engineering design skills in the K-12 classroom.

description: We study a hundred of galaxies from the spectroscopic Sloan Digital Sky Survey with individual detections in the Far-Infrared Herschel PACS bands (100 or 160 $μ$m) and in the GALEX Far-UltraViolet band up to z$\sim$0.4 in the COSMOS and Lockman Hole fields. The galaxies are divided into 4 spectral and 4 morphological types. For the star forming and unclassifiable galaxies we calculate dust extinctions from the UV slope, the H$α$/H$β$ ratio and the $L_{\rm IR}/L_{\rm UV}$ ratio. There is a tight correlation between the dust extinction and both $L_{\rm IR}$ and metallicity. We calculate SFR$_{total}$ and compare it with other SFR estimates (H$α$, UV, SDSS) finding a very good agreement between them with smaller dispersions than typical SFR uncertainties. We study the effect of mass and metallicity, finding that it is only significant at high masses for SFR$_{Hα}$. For the AGN and composite galaxies we find a tight correlation between SFR and L$_{IR}$ ($σ\sim$0.29), while the dispersion in the SFR - L$_{UV}$ relation is larger ($σ\sim$0.57). The galaxies follow the prescriptions of the Fundamental Plane in the M-Z-SFR space.
