description: Continuum Vlasov simulations can be utilized for highly accurate modelling of fully kinetic plasmas. Great progress has been made recently regarding the applicability of the method in realistic plasma configurations. However, a reduction of the high computational cost that is inherent to fully kinetic simulations would be desirable, especially at high velocity space resolutions. For this purpose, low-rank approximations can be employed. The so far available low-rank solvers are restricted to either electrostatic systems or low dimensionality and can therefore not be applied to most space, astrophysical and fusion plasmas. In this paper we present a new parallel low-rank solver for the full six-dimensional electromagnetic Vlasov-Maxwell equations with a compression of the particle distribution function in velocity space. Special attention is paid to mass conservation and Gauss's law. The low-rank Vlasov solver is applied to standard benchmark problems of plasma turbulence and magnetic reconnection and compared to the full grid method. It yields accurate results at significantly reduced computational cost.

Semantic Representation of Teacher Autonomy: A Grounded Theory Study
Publisher: name: The University Of Kurdistan
Year: 2022

description: The present study aimed to represent the autonomy of teachers adopting the\ngrounded theory semantically. The research approach of this study was qualitative,\nand the theory method was grounded theory. The statistical population included\nall primary school teachers and principals in Lorestan, Iran. To collect qualitative\ndata, interviews were conducted with 45 experienced teachers, school principals,\nspecialists, and professors. In this study, the purposive sampling method was used\nfor participant selection. The sampling method was purposefully continued until\nthe researcher reached theoretical saturation. The basic indicators of the model of\nautonomy of schoolteachers were identified using a review of the research\nbackground and content analysis of the interviews. Next, the three stages of axial\ncoding, selective coding, and main category resulted in six main categories: axial\nPhenomenon, Causal Conditions, Background Conditions, Interfering Conditions,\nStrategic Conditions, and Consequences Conditions. Teachers' Autonomy Model\nwas developed, including 23 axial codes in the form of six selective codes for the\nsix dimensions of axial Phenomenon, causal conditions (with four axial codes),\nbackground conditions (with two axial codes), interfering factors (with two axial\ncodes), strategy (with seven axial codes), and consequences (with four axial\ncodes). The extracted qualitative model can be used in policy-making and\nprofessional autonomy planning, especially in the professional development of\nteachers

description: Metafibers expand the functionalities of conventional optical fibers to unprecedented nanoscale light manipulations by integrating metasurfaces on the fiber tips, becoming an emerging light-coupling platform for both nanoscience and fiber optics communities. Mostly exploring the isolated bare fibers, current metafibers remain as proof-of-concept demonstrations due to a lack of standard interfaces with the universal fiber networks. Here, we develop new methodologies to fabricate well-defined plasmonic metasurfaces directly on the end facets of commercial single mode fiber jumpers using standard planar technologies and provide a first demonstration of their practical applications in the nonlinear optics regime. Featuring plug-play connections with fiber circuitry and arbitrary metasurfaces landscapes, the metafibers with tunable plasmonic resonances are implemented into fiber laser cavities, yielding all-fiber sub-picosecond (minimum 513 fs) soliton mode locked lasers at optical wavelengths of 1.5 micrometer and 2 micrometer, demonstrating their unusual polarimetric nonlinear transfer functions and superior saturation absorption responses. Novel insights into the physical mechanisms behind the saturable absorption of plasmonic metasurfaces are provided. The nanofabrication process flow is compatible with existing cleanroom technologies, offering metafibers an avenue to be a regular member of functionalized fiber components. The work paves the way towards next generation of ultrafast fiber lasers, optical frequency combs, optical neural networks and ultracompact "all-in-fibers" optical systems for sensing, imaging, communications, and many others.

description: Superconducting Pr$_2$CuO$_x$, $x\simeq 4$ (PCO) films with $T^\prime$ structure and a $T_c$ of 27 K have been investigated by various optical methods in a wide frequency (7 - 55000 cm$^{-1}$) and temperature (2 to 300 K) range. The optical spectra do not reveal any indication of a normal-state gap formation. A Drude-like peak centered at zero frequency dominates the optical conductivity below 150 K. At higher temperatures, it shifts to finite frequencies. The detailed analysis of the low-frequency conductivity reveals that the Drude peak and a far-infrared (FIR) peak centered at about 300 cm$^{-1}$ persist at all temperatures. The FIR-peak spectral weight is found to grow at the expense of the Drude spectral weight with increasing temperature. The temperature dependence of the penetration depth follows a behavior typical for $d$-wave superconductors. The absolute value of the penetration depth for zero temperature is 1.6 $μ$m, indicating a rather low density of the superconducting condensate.

description: Comprehensive coordinated specialty care programs for first episode psychosis have been widely implemented in other countries, but not in the U.S. The National Institute of Mental Health’s (NIMH) Recovery After Initial Schizophrenia Episode (RAISE) initiative focused on the development and evaluation of first episode treatment programs designed for the U.S. healthcare system. This paper describes the background, rationale, and nature of the intervention developed by the Early Treatment Program project, the NAVIGATE program, with a particular focus on its psychosocial components. NAVIGATE is a team-based, multi-component treatment program designed to be implemented in routine mental health treatment settings and aimed at guiding people with a first episode of psychosis (and their families) towards psychological and functional health. The core services provided in the NAVIGATE program include the Family Education Program, Individual Resiliency Training, Supported Employment and Education, and Individualized Medication Treatment. NAVIGATE embraces a shared decision-making approach with a focus on strengths and resiliency, and collaboration with clients and family members in treatment planning and reviews. The NAVIGATE program has the potential to fill an important gap in the U.S. healthcare system by providing a comprehensive intervention specially designed to meet the unique treatment needs of persons recovering from a first episode of psychosis. The program is currently being evaluated in cluster randomized controlled trial comparing NAVIGATE to usual community care.

description: We have grown La$_{0.3}$Sr$_{0.7}$CoO$_{3-δ}$ thin films by pulsed laser deposition on (LaAlO$_3$)$_{0.3}$(Sr$_2$TaAlO$_3$)$_{0.7}$ substrates with and without a protective LaAlO$_3$ capping layer and investigated their structural and magnetic properties. We have observed that, in the uncapped films, the Curie temperature strongly decreased after annealing in helium atmosphere, and it significantly decreased even in samples stored for several weeks at room temperature. The decrease of the Currie temperature is caused by an increase of the concentration of oxygen vacancies, δ. However, we show that already a 3 nm thin LaAlO$_3$ capping layer can essentially conserve δ at room temperature, and it considerably slows down the formation of oxygen vacancies at elevated temperatures.
Explaining the Structural Relationship of Teachers' Readiness for Change, Their Perception of Social Capital, and Teachers' Tendency to Participate: The Case Study Education in Fars Province
Publisher: name: The University Of Kurdistan
Year: 2022

description: The main aim of this study this study was explaining the structural model of teacher's\nperception of school's social capital and teacher's psychological capital with their\nreadiness for change in primary schools. The research statistical population was\nincluded all primary school teachers (17500) in Fars province, that 733 of them were\nselected as the research sample by using systematic sampling method. The research\ninstruments were included three questionnaires: social capital, psychological capital\nand readiness for changing, which were distributed and collected after calculating\nvalidity (speciation analysis) and reliability (Cronbach's alpha). Research data were\nanalyzed using one-sample t-test, Pearson's correlation's matrix and multivariate\nregression (structural equation model) and also Amos23 and Spss25 software.\nFindings showed that while the average dimension of social network was higher than\nthe desired level, the rest of the dimensions of social capital and the average total of\nsocial capital was less than the desired level. The average of teacher’s psychological\ncapital and all its dimensions was higher than desired. Examining the simultaneous\nrole of social capital and psychological capital in predicting readiness for change, it\nwas concluded that social capital loses its predictive power for readiness for\nchanging (β= 0/07 & p= NS) and psychological capital have a positive and\nsignificant predictive power for readiness for change (β= 0/62 & p< 0/01). The output\nof this research can be use by managers, teachers and other staff in different domains\nto providing readiness ground for change by developing and strengthening the\ncapacities of psychological capital

Presenting a Model of Resilient Schools based on Grounded Theory
Publisher: name: The University Of Kurdistan
Year: 2022

description: Improving the quality of education and empowering students are important issues in\neducational systems, and it is necessary to identify influential factors for them. One of the\nfactors that can help improve the educational system is enhancing resilience in schools.\nResilient schools are those that create conditions for students and teachers to be able to respond\nto the challenges of school and community and help them achieve educational goals in difficult\nconditions, by providing necessary space and educational facilities. Therefore, the present\narticle aims in identifying the dimensions and components of resilient schools to present a\nrelated model. In this regard, a qualitative method based on the grounded theory approach is\nused. The statistical population of this research includes faculty members, psychology\nspecialists, and school principals in Kurdistan province. A purposeful sampling method is used\nto select the sample based on the saturation rule by using sixteen interviews, and for more\nassurance, it is continued up to twenty interviews. Data collection was conducted through semistructured\ninterviews and data analysis was done through open, axial, and selective coding\nmethods. The findings indicate that causal conditions (development of student’s abilities,\nestablishing proper communication with students, learning life skills, and improving the status\nof teachers) through the central phenomenon (resilient schools) influence the strategies for\nachieving resilient schools. These strategies include making the educational environment\nhappy, developing parents’ participation, providing extra-curricular activities, appropriateness\nof curriculum content, supporting teachers, making the curriculum content applicable, and\ninstruction. Some intervening conditions (salary and benefits, recruitment and selection of\nhuman power, and decentralization) as well as contextual conditions (facilities, leadership, and\nteaching-learning processes) influence these strategies. Finally, the consequences of these\nstrategies and their impact include mental health, self-awareness, cooperation, participation,\nand promotion of general health

description: The present paper intends to be a new study of a widely used precursor in nanostructure deposition and FEBID processes with a focus on its fragmentation at collisions with low-energy electrons. Newer developments in nanotechnology with applications to Focused Electron Beam Induced Deposition (FEBID) and Extreme Ultraviolet Lithography (EUVL), based on irradiation-induced chemistry come with advances in the size of the nanostructures at the surface and their flexibility in creating highly complex 3D structures. The deformation in the main structures of the FEBID process characterized by elongation, reduction in diameter of the main structure, and the deposition of additional thin layers around the structure on the substrate are results of the effect of the secondary electrons, olliding with energies lower than 20eV. Fe(CO)5 is one of the most used compounds in FEBID processes as it has high pressure and has been shown to provide high purity deposits (over 90%). This paper combines experiment and simulations to study electron scattering from Fe(CO)5, while experimental data on dissociative electron attachment is presented using the Velocity Slice Map Imaging (VMI) technique that combined with data collected on the CLUSTER apparatus at Comenius University, Bratislava and Quantemol-N simulations present the fragmentation pathways and channel distribution for each of the resulting negative ions at low energies. The Quantemol-N simulation package is used to study collision processes of low-energy electrons with Fe(CO)5 molecules including elastic, electronic excitation, and dissociative electron attachment (DEA) cross-sections.

description: The fundamental property of most single-electron devices with quasicontinuous quasiparticle spectrum on the island is the periodicity of their transport characteristics in the gate voltage. This property is robust even with respect to placing the ferroelectric insulators in the source and drain tunnel junctions. We show that placing the ferroelectric inside the gate capacitance breaks this periodicity. The current-voltage characteristics of this SET strongly depends on the ferroelectric polarization and shows the giant memory-effect even for negligible ferroelectric hysteresis making this device promising for memory applications.

description: Let $H$ be a graph on $n$ vertices and let the blow-up graph $G[H]$ be defined as follows. We replace each vertex $v_i$ of $H$ by a cluster $A_i$ and connect some pairs of vertices of $A_i$ and $A_j$ if $(v_i,v_j)$ was an edge of the graph $H$. As usual, we define the edge density between $A_i$ and $A_j$ as $d(A_i,A_j)=\frac{e(A_i,A_j)}{|A_i||A_j|}.$ We study the following problem. Given densities $γ_{ij}$ for each edge $(i,j)\in E(H)$. Then one has to decide whether there exists a blow-up graph $G[H]$ with edge densities at least $γ_{ij}$ such that one cannot choose a vertex from each cluster so that the obtained graph is isomorphic to $H$, i.e, no $H$ appears as a transversal in $G[H]$. We call $d_{crit}(H)$ the maximal value for which there exists a blow-up graph $G[H]$ with edge densities $d(A_i,A_j)=d_{crit}(H)$ $((v_i,v_j)\in E(H))$ not containing $H$ in the above sense. Our main goal is to determine the critical edge density and to characterize the extremal graphs.

description: This research aims to identify the competencies of school principals based on\nIranian studies for effective leadership in schools. Therefore, this research has\nbeen developed using a qualitative method and using meta-synthesis strategy.\nTherefore, after checking the keywords of managers' competence in internal\ndatabases, 150 types of research were extracted from 2005 to 2020, and finally, 70\ntypes of research were included in the final analysis. The results included 19\nprimary pre-organizer themes and six secondary pre-organizer themes. Secondary\npre-organizer themes include; Individual competencies (with primary preorganizer\nthemes: personal, professional, and functional), interactive\ncompetencies (with primary pre-organizer themes: intra-organizational\ninteractions, extra-organizational interactions, and team building and teamwork),\njob competencies (with primary pre-organizer themes: career development, human\nresource management, and job recognition), organizational competencies (with\nprimary pre-organizer themes: leadership, managerial-executive, soft capacity\nmaking, organizational effectiveness, and organizational quality), technicalspecialized\ncompetencies (with primary pre-organizer themes: technological skills\nand knowledge skills), financial competencies (with primary pre-organizer\nthemes: budgeting, financial management and planning, and financial efficiency\nand effectiveness). In the end, in addition to the network of themes, a competency\nmodel of school principals has also been drawn based on the results

description: Previous studies concerned with the relation of proximity to the September 11, 2001 terrorist attacks and subsequent psychopathology have produced conflicting results. The goals of this analysis are to assess the appropriateness of using Bayesian hierarchical spatial techniques to answer the question of the role of proximity to a mass trauma as a risk factor for psychopathology. Using a set of individual-level Medicaid data for New York State, and controlling for age, gender, median household income and employment-related exposures, we applied Bayesian hierarchical modeling methods for spatially-aggregated data. We, we found that distance from the World Trade Center site in the post-attack time period was associated with increased risk of anxiety-related diagnoses. In the months following the attack, each two mile increment in distance closer to the World Trade Center site was associated with a seven percent increase in anxiety-related diagnoses in the population. No similar association was found during a similar time period in the year prior to the attacks. We conclude that spatial variables help more fully describe post-terrorism psychiatric risk and may help explain discrepancies in the existing literature about these attacks. These methods hold promise for the characterization of disease risk where spatial patterning of ecologic-level exposures and outcomes merits consideration.

description: We compute non-linear corrections to the matter power spectrum taking the time- and scale-dependent free-streaming length of neutrinos into account. We adopt a hybrid scheme that matches the full Boltzmann hierarchy to an effective two-fluid description at an intermediate redshift. The non-linearities in the neutrino component are taken into account by using an extension of the time-flow framework. We point out that this remedies a spurious behaviour that occurs when neglecting non-linear terms for neutrinos. This behaviour is related to how efficiently short modes decouple from long modes and can be traced back to the violation of momentum conservation if neutrinos are treated linearly. Furthermore, we compare our results at next to leading order to various other methods and quantify the accuracy of the fluid description. Due to the correct decoupling behaviour of short modes, the two-fluid scheme is a suitable starting point to compute higher orders in perturbations or for resummation methods.

description: Motivated by recent suggestions that many Be stars form through binary mass transfer, we searched the APOGEE survey for Be stars with bloated, stripped companions. From a well-defined parent sample of 297 Be stars, we identified one mass-transfer binary, HD 15124. The object consists of a main-sequence Be star ($M_{\rm Be}=5.3\pm 0.6 \,M_{\odot}$) with a low-mass ($M_{\rm donor}=0.92\pm 0.22\,M_{\odot}$), subgiant companion on a 5.47-day orbit. The emission lines originate in an accretion disk caused by ongoing mass transfer, not from a decretion disk as in classical Be stars. Both stars have surface abundances bearing imprint of CNO processing in the donor's core: the surface helium fraction is $Y_{\rm He}\approx 0.6$, and the nitrogen-to-carbon ratio is 1000 times the solar value. The system's properties are well-matched by binary evolution models in which mass transfer begins while a $3-5\,M_{\odot}$ donor leaves the main sequence, with the secondary becoming the Be star. These models predict that the system will soon become a detached Be + stripped star binary like HR 6819 and LB-1, with the stripped donor eventually contracting to become a core helium-burning sdOB star. Discovery of one object in this short-lived ($\sim$1 Myr) evolutionary phase implies the existence of many more that have already passed through it and are now Be + sdOB binaries. We infer that $(28_{-16}^{+27})\,\%$ of Be stars have stripped companions, most of which are faint. Together with the dearth of main-sequence companions to Be stars and recent discovery of numerous Be + sdOB binaries in the UV, our results imply that binarity plays an important role in the formation of Be stars.

description: The demand for precision predictions in the field of high energy physics has dramatically increased over recent years. Experiments conducted at the LHC, as well as precision measurements at the intensity frontier such as Belle II require equally precise theoretical predictions to make full use of the acquired data. To match the experimental precision, two-, three- and, for certain quantities, even higher-loop calculations are required. To facilitate such calculations, computer software automating as many steps as possible is required. Yet, each calculation poses different challenges and thus, a high level of configurability is required. In this context we present $\texttt{tapir}$: a tool for identification, manipulation and minimization of Feynman integral families. It is designed to integrate in $\texttt{FORM}$-based toolchains which is common practice in the field. $\texttt{tapir}$ can be used to reduce the complexity of multi-loop problems with cut-filters, topology mapping, partial fraction decomposition and alike.

description: Herein we demonstrate that exposure of mice to chlorine gas causes significant changes in the lung proteome 24 h post exposure. System biology analysis of the proteomic data is consistent with damage to mitochondria and activation of eIF2, the master regulator of transcription and protein translation. Post exposure injection of hemopexin, which scavenges free heme, attenuated mtDNA injury, eIF2a phosphorylation, decreased lung injury and increased survival.

description: Observations of high redshift quasars at $z>6$ indicate that they harbor supermassive black holes (SMBHs) of a billion solar masses. The direct collapse scenario has emerged as the most plausible way to assemble SMBHs. The nurseries for the direct collapse black holes are massive primordial halos illuminated with an intense UV flux emitted by population II (Pop II) stars. In this study, we compute the critical value of such a flux ($J_{21}^{\rm crit}$) for realistic spectra of Pop II stars through three-dimensional cosmological simulations. We derive the dependence of $J_{21}^{\rm crit}$ on the radiation spectra, on variations from halo to halo, and on the impact of X-ray ionization. Our findings show that the value of $J_{21}^{\rm crit}$ is a few times $\rm 10^4$ and only weakly depends on the adopted radiation spectra in the range between $T_{\rm rad}=2 \times 10^4-10^5$ K. For three simulated halos of a few times $\rm 10^{7}$~M$_{\odot}$, $J_{21}^{\rm crit}$ varies from $\rm 2 \times 10^4 - 5 \times 10^4$. The impact of X-ray ionization is almost negligible and within the expected scatter of $J_{21}^{\rm crit}$ for background fluxes of $J_{\rm X,21} \leq 0.1$. The computed estimates of $J_{21}^{\rm crit}$ have profound implications for the quasar abundance at $z=10$ as it lowers the number density of black holes forming through an isothermal direct collapse by a few orders of magnitude below the observed black holes density. However, the sites with moderate amounts of $\rm H_2$ cooling may still form massive objects sufficient to be compatible with observations.

description: This paper presents a low-power ECG recording system-on-chip (SoC) with on-chip low-complexity lossless ECG compression for data reduction in wireless/ambulatory ECG sensor devices. The chip uses a linear slope predictor for data compression, and incorporates a novel low-complexity dynamic coding-packaging scheme to frame the prediction error into fixed-length 16-bit format. The proposed technique achieves an average compression ratio of 2.25x on MIT/BIH ECG database. Implemented in a standard 0.35 um process, the compressor uses 0.565K gates/channel occupying 0.4 mm2 for four channels, and consumes 535 nW/channel at 2.4 V for ECG sampled at 512 Hz. Small size and ultra-low power consumption makes the proposed technique suitable for wearable ECG sensor applications.

description: First-episode psychosis typically emerges during late adolescence or young adulthood, interrupting achievement of crucial educational, occupational, and social milestones. Recoveryoriented approaches to treatment may be particularly applicable to this critical phase of the illness, but more research is needed on the life and treatment goals of individuals at this stage. Open-ended questions were used to elicit life and treatment goals from a sample of 100 people hospitalized for first-episode psychosis in an urban, public-sector setting in the southeastern United States. Employment, education, relationships, housing, health, transportation were the most frequently stated life goals. When asked about treatment goals, participants' responses included wanting medication management, reducing troubling symptoms, uncertainty, a desire to simply be well, engaging in counseling, and attending to their physical health. In response to queries about specific services, most indicated a desire for both vocational and educational services, as well as assistance with symptom and drug abuse. These findings are interpreted and discussed in light of emerging or recently advanced treatment paradigms—recovery and empowerment, shared decision-making, community and social reintegration, and phase-specific psychosocial treatment. Integration of these paradigms would likely promote recovery-oriented tailoring of early psychosocial interventions, such as supported employment and supported education, for first-episode psychosis.

description: This study examined rates and correlates of non-suicidal self-injury (NSSI) across three non-clinical adolescent samples from different countries. Surveys were administered to 1862 adolescents (Mage=15.69, S.D.=0.87) from Italy (n=827), the Netherlands (n=675), and United States (n=360), including measures of NSSI, substance use, internal (i.e., depressive symptoms, loneliness), and interpersonal factors (i.e., peer victimization, peer preference). After controlling for socio-demographic differences, similar prevalence of NSSI was found across the three samples, with approximately 24% of the adolescents reporting at least one NSSI episode within the last year. Multivariate logistic regressions showed that adolescents' victimization and higher levels of depressive symptoms and family-related loneliness were associated concurrently with NSSI comparably in all three samples. However, multi-group analyses indicated that the association between NSSI and substance use varied significantly across samples, indicating that NSSI related more strongly to substance use (i.e., cigarette smoking and frequent marijuana use) in the sample from the United States rather than the samples from the Netherlands and Italy. Findings provide evidence of NSSI and suggest high similarities in rates and correlates across samples from different countries. Future research should further explore NSSI cross-nationally.

description: We consider the charged d-dimensional black holes in a cavity in extended phase space and investigate the heat engine and the Joule-Thomson (JT) expansion. Since the phase structure of black holes in a cavity is similar to anti-de-sitter (AdS) cases, we take black holes in a cavity as the working substance in the heat engine and calculate their efficiency in Carnot cycle and rectangular cycle. Also, we discuss whether the JT expansion of charged black holes in a cavity is consistent with AdS cases and conclude the effect of different boundary conditions on black hole thermodynamics.
