description: This research addresses the use of mobile devices with both embedded and external sensors to provide contextualized help, advice, and remediation to learners engaged in real-world learn-by-doing tasks. This work is situated within the context of learning a complex procedure, in particular emergency responders learning to conduct urban search and rescue operations. Research issues include the design and delivery of contextualized performance support and the inferring of learner actions and intentions from sensor data to ensure that the right support is delivered just in time, as it is relevant to what the learner is doing.

Year: 2025
Subjects: classificationCode: 50
subject: Philosophy and religious studies

description: This study examined the impact of an evidence-based coaching intervention within a Qatari government preparatory (middle) school. The sample consisted of 40 male students aged between 13 and 16 years old (mean age 14.2). The sample was randomly selected and randomly divided into two groups to conduct a randomized controlled trial. The coaching program was part of a coaching club established for the purposes of this study. The coaching group students took part in a twenty-four-session evidence-based coaching program (teacher facilitated) that included topics such as goal setting, leadership skills, coaching, and personality types. Pre and post measures were obtained for both groups. The measures consisted of the Big-Five personality traits survey and the Satisfaction with Life Scale. In addition to the quantitative measures, interviews were held with eight randomly selected students from the coaching group to increase the qualitative dimension of the results. Both groups showed a decrease in satisfaction with life as well as most of the personality traits of the period of the school year. However, the decrease was overall slighter with coaching group students. In addition, the coaching group showed a 40% higher rate of goal achievement compared with the control group. Moreover, the interviews strongly showcased both the students’ interest in the coaching program and its contribution to their wellbeing and engagement with their academic and personal goals. This study revealed the urgent need to pay attention to students’ well-being in Qatar’s schools and proposed life coaching as a promising intervention to fill that gap. Limitations of the study and directions for future research are discussed.
The brain's numerical waterscape

Your brain has its own waterscape: whether you are reading or sleeping, fluid flows around or through the brain tissue and clears waste in the process. These physiological processes are crucial for the well-being of the brain. In spite of their importance we understand them but little, and mathematical modelling could play a crucial role in gaining new insight. Surprisingly little attention has been paid to the mathematics and numerics of the brain’s waterscape however, and even fundamental knowledge is missing.

After an introduction to brain physiology, I will discuss mathematical and numerical aspects relating to the brain's waterscape focusing on two scales - viewing the brain as a multi-network poroelastic medium at the macroscale, and zooming in to study electrical, chemical and mechanical interactions between brain cells at the microscale.

description: The plasmoid instability in evolving current sheets has been widely studied due to its effects on the disruption of current sheets, the formation of plasmoids, and the resultant fast magnetic reconnection. In this Letter, we study the role of the plasmoid instability in two-dimensional magnetohydrodynamic (MHD) turbulence by means of high-resolution direct numerical simulations. At sufficiently large magnetic Reynolds number ($R_m=10^6$), the combined effects of dynamic alignment and turbulent intermittency lead to a copious formation of plasmoids in a multitude of intense current sheets. The disruption of current sheet structures facilitates the energy cascade towards small scales, leading to the breaking and steepening of the energy spectrum. In the plasmoid-mediated regime, the energy spectrum displays a scaling that is close to the spectral index $-2.2$ as proposed by recent analytic theories. We also demonstrate that the scale-dependent dynamic alignment exists in 2D MHD turbulence and the corresponding slope of the alignment angle is close to 0.25.

Este periodo fue considerado como un evento El Niño, que según Índice Oceánico El Niño (ONI, por sus siglas en inglés), alcanzó la magnitud débil.
 Asumiendo una propagación de ondas en el primer modo baroclínico, se logró aislar, en estructuras meridionales, las contribuciones individuales de Kelvin y tres primeros modos de Rossby sobre el nivel del mar (Boulanger y Menkes, 1995 y 1999), donde se identificó la propagación de un paquete de ondas en Setiembre del 2018, el cual aparentemente favoreció al inicio de las condiciones cálidas en la región central del Pacífico. Mediante los coeficientes de proyección meridional, este estudio se centra en describir la dinámica y participación de ondas ecuatoriales largas en el evento El Niño 2018/2019.

description: The present work describes the investigation of secondary metabolites produced by rhizospheric soil isolate Streptomyces levis with respect to partial purification, bioactivity, structural elucidation, and docking study. MIC (Minimum Inhibitory Concentration) of the fraction was found to be 16 µg/mL, 32 µg/mL, and 8 µg/mL against S. aureus, E. coli, and C. albicans respectively. The fraction exhibited an IC50 of 90.48 μg/mL and 59.10 µg/mL against L929 and HeLa cell lines respectively. Spectroscopic analysis showed abundant of Isofucosterol 3-O-[6-O-(9-Octadecanoyl)-b-D-glucopyranoside], and Viniferal. These compounds were docked against receptor molecules E6, E7, Caspase-3, and Bcl2. The in-silico results suggested that all the secondary metabolites showed higher docking scores than the standard compound 5-Fluorouracil. Molecular docking study and published literature suggested that Isofucosterol 3-O-[6-O-(9-Octadecanoyl)-b-D-glucopyranoside] inactivated viral oncoprotein E7 and arrested the cell cycle from entering in S phase. Viniferal induced apoptosis by inactivation of Bcl2.

description: The desires, policies, and governmental concepts of a people can usually be found in their organic laws and statutory enactments. This study is an investigation of the resolutions, reports, amendments, debates and final provisions made by the delegates of the Texas Constitutional Convention of 1875 on the question of education. ... The purposes of the investigation are: (1) to discover what educational concepts have been fostered during the history of Texas since the victory for independence, and what concepts crystallized into provisions in the organic law. (2) To determine the causes and influences which operated in making the constitutional provisions for education in the Constitution of 1876. (3) To furnish information in brief compass on the development of educational policies as controlled by the Constitutions and accompanying laws to citizens of Texas and to other interested persons with the hope of making a contribution in the solution of present and future problems of education in Texas. A need seems to exist for a study which may assist in clarifying the causes of the presence of some of the educational provisions in the Constitution of 1876. Constitutional provisions are stabilizing factors in the administration of the affairs of government. Detailed restraints, limitations, and specifications in the organic law always have a tendency to stabilize practice in any department of government at the stage of progress reached at the period when the provision goes into effect. Changes in conditions which require different provisions are disregarded sometime with detrimental consequences to the progress of social enterprises all because of constitutional restrictions made to meet the need of conditions that have long since passed away. Whether or not this is true of the Texas Constitution of 1876 is probably a debatable question. To understand the original motives, hopes, beliefs, and concepts of the framers of this instrument should help citizens of today come to safer conclusions on the subject of education and should guide their attitudes regarding future efforts in dealing with educational policies

description: While gesture interfaces become pervasive, most existing approaches are undesirable for mobile devices because of the high power consumption, or the inconvenience that users need to wear/hold specific sensors. In this paper, we present a contactless gesture recognition system for mobile devices using proximity sensors.

The system allows a user to interact with mobile devices using intuitive gestures, without touching the screen or wearing/holding any additional device.

Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: We obtain a Beale-Kato-Majda-type criterion with optimal frequency and temporal localization for the 3D Navier-Stokes equations. Compared to previous results our condition only requires the control of Fourier modes below a critical frequency, whose value is explicit in terms of time scales. As applications it yields a strongly frequency-localized condition for regularity in the space $B^{-1}_{\infty,\infty}$ and also a lower bound on the decaying rate of $L^p$ norms $2\leq p <3$ for possible blowup solutions. The proof relies on new estimates for the cutoff dissipation and energy at small time scales which might be of independent interest.

We show that the proposed method allows significant progress including the handling of operator ordering.

We propose a tiny, fully-printed system on flexible substrates, which guarantees flexibility and simplifies attachment to the body, and allows for detection of high stress values in form of a binary classification. A major contribution of this paper is the design of the printed hardware, including a novel way to optimize the hardware parameters, which is done via an evolutionary algorithm.

Towards a Model Independent Treatment of Future Solar Neutrino Data

description: Possibilities of a model independent treatment of the data from future real-time solar neutrino experiments (SNO, Super-Kamiokande and others) are discussed. It is shown that in the general case of transitions of the initial solar $ν_e$'s into $ν_μ$ and/or $ν_τ$ the total flux of initial $^8\mathrm{B}$ neutrinos and the $ν_e$ survival probability can be determined directly from the experimental data. Relations between observable quantities are derived, which, if confronted with the experimental data, would allow to reveal the presence of sterile neutrinos in the solar neutrino flux on the earth. Neutrino transitions due to spin and resonant spin-flavour precession in the magnetic field of the sun are shortly discussed.

description: We investigate the thermal equilibrium properties of kinks in a classical $ϕ^4$ field theory in $1+1$ dimensions. The distribution function, kink density, and correlation function are determined from large scale simulations. A dilute gas description of kinks is shown to be valid below a characteristic temperature. A double Gaussian approximation to evaluate the eigenvalues of the transfer operator enables us to extend the theoretical analysis to higher temperatures where the dilute gas approximation fails. This approach accurately predicts the temperature at which the kink description breaks down.

description: Constraints occur in many application areas of interest to evolutionary computation. The area considered here is Bayesian networks (BNs), which is a probability-based method for representing and reasoning with uncertain knowledge. This work deals with constraints in BNs and investigates how tournament selection can be adapted to better process such constraints in the context of abductive inference. Abductive inference in BNs consists of finding the most probable explanation given some evidence. Since exact abductive inference is NP-hard, several approximate approaches to this inference task have been developed. One of them applies evolutionary techniques in order to find optimal or close-to-optimal explanations. A problem with the traditional evolutionary approach is this: As the number of constraints determined by the zeros in the conditional probability tables grows, performance deteriorates because the number of explanations whose probability is greater than zero decreases. To minimize this problem, this paper presents and analyzes a new evolutionary approach to abductive inference in BNs. By considering abductive inference as a constraint optimization problem, the novel approach improves performance dramatically when a BN’s conditional probability tables contain a significant number of zeros. Experimental results are presented comparing the performances of the traditional evolutionary approach and the approach introduced in this work. The results show that the new approach significantly outperforms the traditional one.
Embedding the Zee-Wolfenstein neutrino mass matrix in an SO(10) x A4 GUT scenario

description: We consider renormalizable SO(10) Yukawa interactions and put the three fermionic 16-plets into the 3-dimensional irreducible A_4 representation. Scanning the possible A_4 representation assignments to the scalars, we find a unique case which allows to accommodate the down-quark and charged-lepton masses. Assuming type II seesaw dominance, we obtain a viable scenario with the Zee-Wolfenstein neutrino mass matrix, i.e., the Majorana mass matrix with a vanishing diagonal. Contributions from the charged-lepton mass matrix resolve the well-known problems with lepton mixing arising from the vanishing diagonal. In our scenario, fermion masses and mixings are well reproduced for both normal and inverted neutrino mass spectra, and b-tau Yukawa unification and definite predictions for the effective mass in neutrinoless double-beta decay are obtained.

description: We report the experimental observation of spin reorientation in the double perovskite Ho$_2$FeCoO$_6$. The magnetic phase transitions in this compound are characterized and studied through magnetization and specific heat, and the magnetic structures are elucidated by neutron powder diffraction. Two magnetic phase transitions are observed in this compound - one at $T_\mathrm{N1} \approx$ 250~K, from paramagnetic to antiferromagnetic, and the other at $T_\mathrm{N2} \approx$ 45~K, from a phase with mixed magnetic structures to a single phase through a spin reorientation process. The magnetic structure in the temperature range 200~K - 45~K is a mixed phase of the irreducible representations $Γ_1$ and $Γ_3$, both of which are antiferromagnetic. The phase with mixed magnetic structures that exists in Ho$_2$FeCoO$_6$ gives rise to a large thermal hysteresis in magnetization that extends from 200~K down to the spin reorientation temperature. At $T_\mathrm{N2}$, the magnetic structure transforms to $Γ_1$. Though long-range magnetic order is established in the transition metal lattice, it is seen that only short-range magnetic order prevails in Ho$^{3+}$ - lattice. Our results should motivate further detailed studies on single crystals in order to explore spin reorientation process, spin switching and the possibility of anisotropic magnetic interactions giving rise to electric polarization in Ho$_2$FeCoO$_6$.

description: The magnetic, chemically peculiar A-star HR 710 (HD 15144, ADS 1849A, AB Cet) has a close companion in a nearly circular orbit. Its 3-day period is unusually short for such stars. The system emits moderately hard x-rays, which likely come from a white dwarf secondary (ADS 1849Ab). The Sr II spectrum is very strong, and the resonance lines show similar core-nib structure to the stronger Ca K line. We place only loose constraints on a model. There are indications of a lower electron/gas pressure than expected from the star's parallax and brightness. Strong-line profiles and anomalous excitation/ionization indicate significant deviations from traditional models, fixed by Teff, log{g}, and abundances. Weak spectral-line profiles and wavelength shifts probably indicate abundance patches rather than the presence of a secondary (ADS 1849Ab) spectrum. Our UVES spectra are from only one epoch. Additional low-noise, high-resolution spectra are needed. We discuss the spectrum within the context of abundance stratification.

Energy Dependence of CP-Violation Reach for Monochromatic Neutrino Beam

description: The ultimate goal for future neutrino facilities is the determination of CP violation in neutrino oscillations. Besides $| U(e3) | \ne 0$, this will require precision experiments with a very intense neutrino source and energy control. With this objective in mind, the creation of monochromatic neutrino beams from the electron capture decay of boosted ions by the SPS of CERN has been proposed. We discuss the capabilities of such a facility as a function of the energy of the boost and the baseline for the detector. We compare the physics potential for two different configurations: I) $γ=90$ and $γ=195$ (maximum achievable at present SPS) to Frejus; II) $γ=195$ and $γ=440$ (maximum achievable at upgraded SPS) to Canfranc. We conclude that the SPS upgrade to 1000 GeV is important to reach a better sensitivity to CP violation iff it is accompanied by a longer baseline. In both Setups, the gain in the CP violation sensitivity with a previous knowledge of $| U(e3) |$ is apparent.

description: We present a new way of nano-engineering graphene using defect domains. These regions have ring structures that depart from the usual honeycomb lattice, though each carbon atom still has three nearest neighbors. A set of stable domain structures is identified using density functional theory (DFT), including blisters, ridges, ribbons, and metacrystals. All such structures are made solely out of carbon; the smallest encompasses just 16 atoms. Blisters, ridges and metacrystals rise up out of the sheet, while ribbons remain flat. In the vicinity of vacancies, the reaction barriers to formation are sufficiently low that such defects could be synthesized through the thermally activated restructuring of coalesced adatoms.

Dairy farming is one of the means to meet the growing demand for milk and reduce rural poverty in developing countries. To improve its productivity, many agricultural approaches have been tried, including the Farmer-Field-School (FFS) approach. This study aimed at evaluating the effectiveness of this approach in terms of the adoption of new technologies introduced in small-scale mixed crop livestock systems in Burundi to improve its productivity. A survey was carried out among 98 FFS members and 78 non-members. Technology adoption rates were calculated among FFS and non-FFS members, as well as annual profits per cow. The results showed higher adoption rates among FFS respondents compared to non-FFS respondents for cemented barn floors, traditional lick-blocks, and manure composting, whereas fertilisation of fodder crops, treatment of hay with molasses/urea, and concentrate making were less adopted for the two groups. The annual gross margin was higher for the FFS-group (median: 654 US$) compared to the non-FFS one (median: 542 US$). The study showed that the dissemination of new technologies among non-supported, non-FFS farmers remained low. It is concluded from the results that FFS approach brings about a positive change in farmers’ behaviour towards adopting improved technologies. However, the results identified a number of constraints limiting the effectiveness of this approach including the low availability of inputs, the low financial capacities of farmers, and the complexity and/or the high price of certain technologies. Our results may provide useful information for strengthening the FFS approach in Burundi. For instance, a consistent financial support and follow-up are important for the sustainability of FFS practices. Harmonizing the market prices along the milk value chain is also proposed to increase incomes from the sale of milk.
Topological excitations in the ferromagnetic Kitaev-Heisenberg model

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: With the advancement in synthesizing and analyzing Kitaev materials, the Kitaev-Heisenberg model on the honeycomb lattice has attracted a lot of attention in the last few years. Several variations, which include additional anisotropic interactions as well as response to external magnetic field, have been investigated and many exotic ordered phases have been discussed. On the other hand, quantum spin systems are proving to be a fertile ground to realize and study bosonic analogues of fermionic topological states of matter. Using the spin-wave theory we show that the ferromagnetic phase of the extended Kitaev-Heisenberg model hosts topological excitations. Along the zig-zag edge of the honeycomb lattice we find chiral edge states, which are protected by a non-zero Chern number topological invariant. We discuss two different scenarios for the direction of the spin polarization namely $[001]$ and $[111]$, which are motivated by possible directions of applied field. Dynamic structure factor, accessible in scattering experiments, is shown to exhibit signatures of these topological edge excitations. Furthermore, we show that in case of spin polarization in $[001]$ direction, a topological phase transition occurs once the Kitaev couplings are made anisotropic.

Stressores nos Anestesiologistas Portugueses – uma perspectiva pós-COVID-19
Creators: name: Dias Vaz, Marta
Publisher: name: Revista da Sociedade Portuguesa de Anestesiologia
Year: 2023

description: Introdução: O burnout e stress ocupacional são problemas comuns entre os Anestesiologistas. A pandemia por COVID-19 comportou uma sobrecarga dos serviços de saúde e contribuiu para um agravamento desta problemática. O nosso objetivo era identificar os principais indutores de stress nos Anestesiologistas no período pós-pandémico.




Material e Métodos: Estudo observacional transversal descritivo e analítico dirigido aos membros da Sociedade Portuguesa de Anestesiologia (SPA). Foi aplicado o “Questionário de Stressores nos Anestesiologistas” (QSA), que avalia quantitativamente os principais indutores de stress e estratifica-os em 3 dimensões: stress clínico, de equipa e organizacional. Para comparações entre grupos foram utilizados o teste t para amostras independentes e one-way ANOVA.




Resultados: Cento e vinte e três médicos responderam ao questionário. A maioria dos participantes era do sexo feminino (74%) e trabalhava na região Norte (46%). As mulheres reportaram mais stress clínico e de equipa. O stress organizacional foi superior nos Anestesiologistas com atividade frequente em Emergência e inferior naqueles que exerciam só atividade privada.




Discussão e Conclusões: O maior nível de stress nas mulheres vai de encontro ao reportado em período pré-pandémico. O menor stress organizacional em profissionais que trabalham exclusivamente no setor privado pode traduzir melhores condições de trabalho e/ou uma menor interação com doentes COVID-19. A identificação dos principais fatores indutores de stress nos Anestesiologistas portugueses poderá facilitar a implementação de intervenções dirigidas, com o objetivo de reduzir o stress ocupacional.

Landscapes of Variability: An Aesthetics of Variation

description: Landscape, as most spatial formations, can be understood as a multitude of social, ecological and cultural interdependences that hosts the fundamental relations between people and their environment. At the same time, social presence is a necessary requirement for the concept of de-signed landscape to exist, since it is the result of the active participation of people in its configuration and production. While all the above have been true for architectural and landscape design throughout modernity, the COVID 19 health crisis gave them a new meaning and brought them to the forefront. "e pandemic unsettled the balance of our ways of living and threw us within an unknown reality that we entered violently and without warning. In that context, digital technologies seemed to propose the only viable alternative that would allow for the continuation of our social activities. ‘Virtual landscapes’ became part of this array of digital technologies that seemingly came to our aid. In light of Andre’s Leroi-Gourhan approach that every technology is a social construction, that concept could be seen as a refection on the current socio-political status quo: a transition from an ecological-cultural perception of our environment to an aesthetic-digital one. Despite all the above, the post-pandemic experience of this contemporary perception on an ap-plied level, where it concerned the production, configuration and experience of landscapes, provided a rude awakening which diminished the pre-existing euphoria for the identity, the physiognomy and the capabilities it promised, let alone for its implementation. Considering the above, the hypothesis of virtual landscapes as an element of variability might be an alternative. In other words, considering virtual landscapes as an extension or augmentation of the actual ones in ways that could generate multiple possibilities. Landscape therefore becomes augmented and extended virtually through variations that produce multiplicity and variability. "rough that process, landscape can become a cultural host where its aesthetics could transform our social perceptibility. By shaping a multiple context of virtual social presence in the public realm, we can raise awareness and provide guidance by the construction of personal, social and cultural meaning and knowledge of a place, as urban agents of sustainable change.

description:
Adverse childhood experiences (ACEs) confer risk to the mental health of Black youth, but few studies have examined how youth gender, family, and neighborhood factors jointly influence the psychological impact of adversity. This study investigates if family resilience and neighborhood cohesion jointly moderate the link between latent ACE profiles and mental health among Black girls and boys. This study uses data from the National Survey of Children's Health, combined across the years 2016 through 2021, and includes a nationally representative sample of 5,493 Black youth (48% female) between the ages of 12 and 17. Two patterns of ACEs were identified using latent class analysis characterized by no-to-minimal ACE exposure and moderate-to-high ACE exposure. Membership in the high-ACEs class increased the risk for internalizing problems among Black boys (b = 0.56, p < .001) and girls (b = 0.42, p < .01). Only boys in the high-ACEs class who also reported low levels of family resilience and low neighborhood cohesion evidenced an increased risk for externalizing concerns (b = 0.70, p < .001). Conversely, only girls in the high-ACEs class who reported high levels of family resilience and low levels of neighborhood cohesion evidenced an increased risk for externalizing problems (b = 0.69, p < .01). Findings suggest that the impact of ACEs on mental health is not uniform across Black boys and girls, and that family and neighborhood-level factors may collectively shape the impact of ACEs on the mental health among Black youth in unique ways.

description: We calculate the polarisation of $ψ$'s and $Υ$'s produced by the fragmentation of heavy quarks. We find that fragmentation to transversely aligned quarkonium is slightly enhanced relative to longitudinally polarised. This net alignment corresponds to a $\sim 5\%$ asymmetry in the angular distribution of leptons produced in the subsequent decay of the quarkonium. We point out that the leading gluon contribution to $ψ$ and $Υ$ production arises from the evolution of the charm quark fragmentation function, rather than from direct gluon fragmentation.
