description: The purpose of this research work was to highlight the factors which might contribute to the successful deployment of E-learning in individual, technological and institutional perspective in the rural areas of Pakistan. It further proposed that an ICT platform can effectively bridge the identified gaps and deployed an efficient E-learning platform. In order to probe the factors affecting E-learning systems several close ended questionnaires were used. To fill the close ended questionnaire probability cluster sampling technique was used. The adopted close-ended questionnaires were filled by the university students belonging to the rural areas of Pakistan. The results of this study showed that individual perspective consisting of student’s characteristics and instructor’s characteristics had a significant positive effect on the deployment of E-learning. The technological perspective also had a significant positive effect on the E-learning deployment. Additionally, an institutional perspective which consisted of E-learning environment, learning methods, school building and computing resources also had significant positive association on the E-learning deployment in the rural areas of Pakistan.

description: In this work, we show that excellent surface passivation can be obtained on n-type FZ c-Si as well as ptype
Cz c-Si by Al2O3 films deposited by thermal -ALD technique. The surface passivation provided by Al2O3 films
strongly depends on thermal annealing process and the surface recombination as low as 5cm/s can be achieved by
properly annealed Al2O3. The electronic properties of Al2O3/Si interface have been investigated using contactless
surface photovoltage spectroscopy technique. The experimental results indicate that the post-deposition anneal leads
to significant increase in negative fixed charge density in the Al2O3 and suppression of interface states, both lead to
great improvement of surface passivation. In addition, the measured surface photovoltage spectra are compared with
a simplified theoretical model based on charge distribution method. The calculation results suggest that the strike
different behavior of spectra between n-type and p-type samples can be explained in terms of SPV signals generated
by two surface SCRs. The results also predict that the density of negative fixed charge in properly annealed Al2O3 is
high enough to form inversion region close to the wafer surface which is attractive for the realization of novel high
efficiency inversion solar cells.

description: Background: Emotion regulation difficulties are central to posttraumatic stress disorder (PTSD). While cultural differences exist in the ways in which individuals regulate their emotions, researchers have not examined cultural differences in emotion regulation in PTSD.Objective: This study explored emotion regulation in individuals from European and East Asian cultures with and without PTSD. Method: Emotion regulation measures were administered to Caucasian Australian (n = 31) and East Asian Australian (n = 38) trauma survivors with and without PTSD. Results: Caucasian Australians with PTSD scored significantly higher on measures of worry, expressive suppression, thought suppression, rumination, experiential avoidance, and general emotion dysregulation compared to Caucasian Australians without PTSD. Similarly, East Asian Australians with PTSD scored significantly higher on measures of rumination and experiential avoidance than East Asian Australians without PTSD. However, worry, expressive suppression, thought suppression and general emotion dysregulation did not differentiate between East Asian Australians with and without PTSD. Conclusion: These findings suggest that there may be cultural differences in emotion regulation difficulties in PTSD and highlight the need for further research in this area.

description: Fallback in core-collapse supernova explosions is potentially of significant importance for the birth spins of neutron stars and black holes. It has recently been pointed out that the angular momentum imparted onto a compact remnant by fallback material is subtly intertwined with its kick because fallback onto a moving neutron star or black hole will preferentially come for a conical region around its direction of travel. We show that contrary to earlier expectations such one-sided fallback accretion onto a neutron star will tend to produce spin-kick misalignment. Since the baroclinic driving term in the vorticity equation is perpendicular to the nearly radial pressure gradient, convective eddies in the progenitor as well as Rayleigh-Taylor plumes growing during the explosion primarily carry angular momentum perpendicular to the radial direction. Fallback material from the accretion volume of a moving neutron star therefore carries substantial angular momentum perpendicular to the kick velocity. We estimate the seed angular momentum fluctuations from convective motions in core-collapse supernova progenitors and argue that accreted fallback material will almost invariably be accreted with the maximum permissible specific angular momentum for reaching the Alfvén radius. This imposes a limit of $\mathord{\sim}10^{-2}M_\odot$ of fallback accretion for fast-spinning young neutron stars with periods of $\mathord{\sim}20\,\mathrm{ms}$ and less for longer birth spin periods.

description: The local properties of turbulence driven by the magnetorotational instability (MRI) in rotating, shearing flows are studied in the framework of a shearing-box model. Based on numerical simulations, we propose that the MRI-driven turbulence comprises two components: the large-scale shear-aligned strong magnetic field and the small-scale fluctuations resembling magnetohydrodynamic (MHD) turbulence. The energy spectrum of the large-scale component is close to $k^{-2}$, whereas the spectrum of the small-scale component agrees with the spectrum of strong MHD turbulence $k^{-3/2}$. While the spectrum of the fluctuations is universal, the outer-scale characteristics of the turbulence are not; they depend on the parameters of the system, such as the net magnetic flux. However, there is remarkable universality among the allowed turbulent states -- their intensity $v_0$ and their outer scale $λ_0$ satisfy the balance condition $v_0/λ_0\sim \mathrm dΩ/\mathrm d\ln r$, where $\mathrm dΩ/\mathrm d\ln r$ is the local orbital shearing rate of the flow. Finally, we find no sustained dynamo action in the $\mathrm{Pm}=1$ zero net-flux case for Reynolds numbers as high as $45\,000$, casting doubts on the existence of an MRI dynamo in the $\mathrm{Pm}\leq 1$ regime.

description: Chemical plating is the main alternative to screen printing for the metallization of crystalline silicon
solar cells, substituting silver by copper. Yet, because the latter diffuses into silicon and drastically reduces its lifetime, a
nickel layer is deposited underneath to both serve as contact for the emitter and barrier for the copper diffusion. In this
work, an electrochemical metallization process is described for 180 μm-thick bifacial n-PERT silicon solar cells with 80
Ω/ boron emitter in the textured front face and 70 Ω/ phosphorus doping in the chemically etched rear face. After
LASER dielectric opening, nickel electroless and copper electrolytic techniques are carried out with simultaneous
depositions on both faces of the cell, followed by a one-step annealing of the stack. The influence of different annealing
parameters is studied by looking at the nickel silicide characteristics thanks to a combination of structural and electrical
characterizations. Ni(P) electroless and Cu electrolytic depositions are selective. Their growth rates are respectively
around 0.1 and 1 μm/min, and they exhibit the same characteristics on both faces of the cell. On the whole, performances
are quite low (particularly for FF and series resistance), probably due to contact adhesion problems in the chemically
etched rear face. Efficiencies of 12.4% (16.6% for the best cell) are obtained for a 20-minute annealing at 380°C.
Temperatures of 300°C and 750°C lead to shunted cells: the final one-step annealing seems to have a quite narrow
process window.

description: By means of density functional theory based calculations, we study the role of spin-orbit coupling in the new family of ABC hyperferroelectrics [Phys. Rev. Lett. 112, 127601 (2014)]. We unveil an extremely rich physics strongly linked to ferroelectric properties, ranging from the electric control of bulk Rashba effect to the existence of a three dimensional topological insulator phase, with concomitant topological surface states even in the ultrathin film limit. Moreover, we predict that the topological transition, as induced by alloying, is followed by a Weyl semi-metal phase of finite concentration extension, which is robust against disorder, putting forward hyperferroelectrics as promising candidates for spin-orbitronic applications.

description: The Potential Induced Degradation (PID) is one of the most serious degradation which is known to
cause power loss in c-Si PV systems. At present, there are many techniques can be applied to reduce the PID, such as
modified silicon nitride anti-reflection coating (ARC), additional Silicon Oxide (SiO2) dielectric layer, encapsulation
material with improved electrical resistivity and system grounding of the negative pole. Many companies combine
these methods to ensure the anti-PID ability and reliability of PV modules. In this paper, two main cell-level anti-PID
methods are investigated: a. increasing the refractive index of SiNx up to 2.15; b. adding an additional SiO2 dielectric
layer between emitter and ARC by inline ozone generator. The result shows that by both methods, PID resistance
were obtained with the PID testing condition (-1000V, 85, 85%RH, 96hrs) and SiO2 dielectric layer shows more
excellent PID resistivity with power degradation less than 1%. In addition, cells with method b have about 1%
relative improvment in efficiency compared with method a. EQE characterization indicates that the benefit is mainly
from the less light absorption of SiNx layer and a slightly better surface passivation.

description: Efficient prevention of posttraumatic stress disorder (PTSD) needs to target individuals with an increased risk for adverse outcome after trauma. Prognostic or prescriptive biological markers assessed early posttrauma may inform personalized treatment recommendations. To test prognostic and prescriptive effects of early (posttraumatic) autonomic and endocrine markers on PTSD symptom development. Autonomic and endocrine markers were assessed within 12 days posttrauma and before treatment initiation within a randomized placebo-controlled trial investigating repeated oxytocin administration as preventive intervention for PTSD. Linear mixed effects models were used to test the effects of heart rate (variability), resting cortisol, morning cortisol and cortisol awakening response (CAR), cortisol suppression by dexamethasone and resting oxytocin on PTSD symptoms 1.5, 3 and 6 months posttrauma in men (n = 54), women using hormonal contraception (n = 27) and cycling women (n = 19). We found significant prognostic effects of resting oxytocin and cortisol suppression. In women using hormonal contraception, higher oxytocin was associated with higher PTSD symptoms across follow-up. Stronger cortisol suppression by dexamethasone, reflecting increased glucocorticoid receptor feedback sensitivity, was associated with lower PTSD symptoms across follow-up in men, but with higher symptoms at 1.5 months in women using hormonal contraception. These effects were independent of treatment condition. No further significant prognostic or prescriptive effects were detected. Our exploratory study indicates that resting oxytocin and glucocorticoid receptor feedback sensitivity early posttrauma are associated with subsequent PTSD symptom severity. Notably, prognostic effects depended on sex and hormonal contraception use, emphasizing the necessity to consider these factors in biomedical PTSD research.

description: In our previous work, we developed a special printed-AlOx approach for our passivated emitter and
rear cell (PERC) product, named ExcelTonTM-III technology. With this low-cost and safer technology, our PERC
product with 3-busbar (3-BB) pattern design reached an average efficiency of around 20.3 %. In this paper, we
introduce a next-generation AlOx paste, named IP1257-L, to replace the old-version paste of IP1257. One advantage
of IP1257-L is that it provides a higher-passivation-quality AlOx film, resulting in an increase in Voc of 0.4-1.3 mV
and an efficiency gain up to 0.12 % by just replacing IP1257 with IP1257-L. Most importantly, the paste usage of
IP1257-L is less, about 42 % saving compared to that of IP1257. This means the running cost can be further reduced.
We also demonstrate that an average efficiency of 20.84 % with the best efficiency of 21.22 % was achieved in our
production line by integrating IP1257-L paste together with 4-BB pattern design. With this high-performance and
low-usage paste, we believe that this alternative printed-AlOx PERC technology opens the potential for better priceperformance
ratio instead of other vapor-phase-deposited-AlOx PERC technologies.

In a flat spacetime background, we have explicit solutions. We use generalized Fermi-Walker transport to parallel transport the Frenet basis along the trajectory. In flat spacetime, we obtain velocity and acceleration transformations from a uniformly accelerated system to an inertial system. We obtain the time dilation between accelerated clocks. We apply our acceleration transformations to the motion of a charged particle in a constant electromagnetic field and recover the Lorentz-Abraham-Dirac equation.

description: Background: Cumulative evidence suggests that both traumatic stress and posttraumatic stress disorder (PTSD) are cross-sectionally and prospectively linked to cardiovascular disease (CVD). However, their association with proxy markers of atherosclerosis has hardly been investigated. Objective: The objective of this general population study was to relate traumatic stress and PTSD to carotid plaque and intima-media thickness (cIMT). Methods: 3119 adults from the general population were assessed regarding their traditional cardiovascular risk factors, and an ultrasound of the carotid arteries was performed in each participant. Based on a PTSD interview, every participant was assigned to one of three groups: no trauma; trauma, but no PTSD; and trauma with PTSD. The sample was stratified into five age groups. Results: Trauma exposure was reported by 54.5% of the sample and 2.0% had PTSD. Traumatized participants had increased odds of self-reported CVD events compared to those without trauma exposure, even when accounted for CVD risk factors and other covariates (odds ratio [OR] = 1.51; 95% confidence interval [CI]: 1.03–2.22). This association was driven by those aged 70 years or older. Only in those aged 40 to 49 years, there was an association between cIMT and PTSD. There were no further associations between carotid plaque or cIMT and traumatic stress or PTSD. Conclusions: Our findings in concert with prior research suggest that the association between traumatic stress, PTSD and atherosclerosis as well as its clinical endpoints is complex and remains inconclusive. Although traumatic stress and posttraumatic stress disorder have been linked to cardiovascular disease, they were not related to proxy markers of atherosclerosis in this general population study including 3119 adults.

description: Deficiency of texturing technique impedes the upgrade of multi-diamond-wire saw silicon
(MDWS) solar cell to commercial production. In this paper, Nano-textured was applied on diamond-wire saw
multi-crystalline silicon by RIE etching technique. The resultant unique pyramidal nanostructures give
advantages of both light-trapping and electric properties of silicon solar cells. Finally the silicon solar cells
achieved an average efficiency of 18.70%, which gains an efficiency of 0.44% from silicon solar cells with
micron-textured. In particular, the best efficiency of RIE 400nm-MDSS achieved 19.1%, the short circuit
current achieved 290mA. In terms of the open circuit voltages, the influence of the Nano-textured size on the
efficiency also has been investigated. It indicates that a larger texture size gives a higher open circuit voltage.

description: There is a broad evidence-base for the effectiveness of Trauma-Focused Cognitive-Behavioral Therapy (TF-CBT) in treating children and adolescents with posttraumatic stress disorder (PTSD). The effect of therapist characteristics on patient symptoms has been neglected in psychotraumatology research and necessitates further investigation. This study aims to investigate the impact of therapist characteristics (gender, clinical experience and theoretical background) on posttraumatic stress symptoms (PTSS) in a heterogeneous and international sample of traumatized children and adolescents. Data from two RCTs on the effectiveness of TF-CBT in Norway and Germany were included, comprising N = 52 therapists (78.8% female) and N = 153 patients (72.3% female). All therapists underwent thorough training and continuous supervision in TF-CBT. The Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA) assessed pre- and post-treatment served as the outcome variable in a linear mixed-effects model with therapists’ theoretical background, prior clinical experience and gender as independent variables, adjusted for patient gender, measurement time and country. The possibility of an interaction between therapist and patient gender was investigated subsequently. None of the therapist characteristics were significantly related to PTSS. There was no indication of an interaction between patient and therapist gender (p =.878). The lack of evidence for a relationship of therapists’ theoretical orientation and clinical experience with outcome suggests that a wider dissemination of TF-CBT may be warranted. More studies with larger therapist and patient sample sizes and including only community practice are needed.

description: Acidic textured solution by using HF/HNO3 is widely used for the multi-crystalline silicon solar
cells. But, such textured solution is challenging for texturing the diamond wire sawn wafers, since damage layers
do not homogeneously distribute on the silicon wafers. On the other hand, Metal catalyzed chemical etching
(MCCE) using silver nitrate (AgNO3) is an effective method for diamond wire sawn wafers. Such textured
technique involves metal catalyst reaction that is spontaneously formed regardless wafer surface conditions. In this
paper, fine texturing structures were formed on the diamond wire sawn wafers by using MCCE method. In order to
solve the problem of crystal flower, it is necessary to add additives into MCCE solution. The efficiency of silicon
solar cells with the diamond wire sawn silicon and MCCE textured surfaces is higher than that of silicon solar cells
with the slurry wire sawn wafers and acidic textured surfaces. The results indicate that the MCCE method can
become an alternative candidate for texturing the diamond wire sawn wafers and multi-crystalline silicon.

description: Formation of electrical conductors by wet chemical metallization is well-known in the electronics industry,
with decades of implementation in the fabrication of printed circuit boards and microelectronics. However, its usage in the
photovoltaic industry is still in its early stages. As the solar cell fabrication process matures, wet chemical copper
metallization will move from acceptable, to preferred, to required. Relative to screen printed silver paste, copper allows
higher aspect ratio, self-aligned conductors, and compatibility with increasingly complex materials and processes. Many
of the highest efficiency cell architectures already require, or benefit from, wet chemical metallization. Future commodity
cells are predicted to require copper conductors, due to the need to continually improve efficiency while simultaneously
driving costs lower. This paper is a review of the current status of wet chemical metallization in the photovoltaic space,
and a prospectus for where the technology trends are leading. Also included is a brief history of plating in PV, as well as
its advantages, challenges, application to specific cell types, and path to mass adoption.

description: This thesis focuses on the impact of stock liquidity and country-wide factors on return and volatility of Depositary Receipts (DRs). As a case study, it examines the underlying stocks that are traded in the UK and their corresponding DRs that are traded in 46 markets across 25 countries, considering the impact of home/foreign country corruption. The statistical analysis is carried out by using GLS, in addition to WLS and Robust regression as a robustness check for unbalanced panel data which cover the period from 2004 to 2019. This thesis highlights the importance of combining two theories; liquidity preference theory (which asserts that investors prefer highly liquid holdings, as DRs can be liquidated quickly by selling them in one of foreign countries in which they are traded or back to their original stocks in the UK) and international diversification theory (that underlines the importance of DRs in diversifying investments internationally). Also, arbitrageurs can benefit from differences between prices of stock/DR or DR/DR till maintaining their parity when markets become efficient according to efficient market hypothesis. The findings show that; (a) Increase in trading volume, as a proxy for liquidity, of underlying stocks and DRs leads to an increase in return and a decrease in volatility,(b) Inflation has a significant positive effect on return and volatility,(c) Interest rate has a significant negative effect on return and positive effect on volatility,(d) GDP has an unexpectedly significant negative effect on most of countries return, however it has an insignificant effect on volatility,(e) Exchange rate has a significant negative effect on return of most of countries, however, its effect on volatility differs from one country to another,(f) Corruption of home/foreign countries have mostly the same significant negative effects on return, however their effects differ on volatility. Actually, previous studies focused only on these factors partially. Therefore, this thesis fills the gap in knowledge by building more comprehensive model that guides investors/arbitrageurs in their decisions concerning investments in DRs.

description: In this study, we report the deposition of Eu-doped (3wt%) phosphors on planar and textured Si solar
cells via a silicate (SiO2) solution using spin-on film technique to enhance photovoltaic performance. The surface
profile and dimensions of the phosphor particles were examined using electron scanning microscopy (SEM). Optical
reflectance, photoluminescence (PL), and external quantum efficiency (EQE) were used to characterize the
luminescent downshifting (LDS) of the Eu-doped silicate phosphor layer. Current density-voltage (J-V) curves under
AM 1.5G simulation were used to confirm the contribution of LDS and the anti-reflectivity and shading produced by
Eu-doped phosphors-particles of various dimensions. Experiment results revealed that larger phosphor particles have
a more pronounced effect on the shading and reflectance of incident light. For planar solar cells, the short-circuit
current density (Jsc) enhamcement by about 20% was obtained when deposited Eu-doped phosphors on the cells. On
textured solar cells, however, the application of sub-micron Eu-doped phosphor particles increased the Jsc by 5.6%,
far exceeding that of cells with larger Eu-doped phosphor particles (of 1.6%), compared to the reference cell.

description: Background: Children and adolescents in foster care often experience many co-occurring subtypes of maltreatment. However, little is known about different combinations of maltreatment subtypes, referred to as maltreatment classes. Furthermore, the association between those maltreatment classes and ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) has not been investigated in children and adolescents. In previous studies, classes characterized by cumulative maltreatment were associated with severe psychopathological symptoms. So far, no study investigated ICD-11 PTSD and CPTSD. Objective: The first aim of this study was the detection of distinct maltreatment classes by examining frequently co-occurring maltreatment subtypes. The second aim was the examination of the association between those maltreatment classes and ICD-11 PTSD and CPTSD. Method: Participants were 147 children and adolescents currently living in foster care institutions in Lower Austria. Maltreatment history, ICD-11 PTSD and CPTSD were assessed using standardized self-report questionnaires. Latent class analysis was applied to examine maltreatment subtypes. χ2 difference testing was used to examine class associations with PTSD and CPTSD. Results: Three latent classes that comprised different subtypes of maltreatment were identified (limited maltreatment, n = 49; high neglect, n = 53; cumulative maltreatment, n = 45). Cumulative maltreatment was associated with higher symptom severity of PTSD and CPTSD than the limited maltreatment and the high neglect class, with effect sizes ranging from 0.62 to 0.93. Conclusions: The association of the cumulative maltreatment class with the highest symptom severity of PTSD and CPTSD highlights the detrimental effect of cumulative maltreatment. The detection of a high neglect class identifies children and adolescents, who are at high-risk of experiencing future maltreatment because of their previous experiences of neglect and the associated lack of protection. The examination of the association of distinct maltreatment classes with ICD-11 PTSD and CPTSD might provide implications for targeted prevention, assessment and treatment. • Three classes of childhood maltreatment were detected (limited maltreatment, high neglect, cumulative maltreatment).• Class membership was associated with ICD-11 PTSD and CPTSD.• Based on the findings, tailored prevention and intervention is possible for high-risk individuals.

description: Batched linear solvers play a vital role in computational sciences, especially in the fields of plasma physics and combustion simulations. With the imminent deployment of the Aurora Supercomputer and other upcoming systems equipped with Intel GPUs, there is a compelling demand to expand the capabilities of these solvers for Intel GPU architectures. In this paper, we present our efforts in porting and optimizing the batched iterative solvers on Intel GPUs using the SYCL programming model. These new solvers achieve impressive performance on the Intel GPU Max 1550s (Ponte Vecchio GPUs) which surpass our previous CUDA implementation on NVIDIA H100 GPUs by an average of 2.4x for the PeleLM application inputs. The batched solvers are ready for production use in real-world scientific applications through the Ginkgo library, complementing the performance portability of the batched functionality of Ginkgo.

description: We report on the successful synthesis and on the properties of polycrystalline AgPbmSnSe2+m (m = ++++, 100, 50, 25) samples with a rock salt structure. Between 160 K and 400 K, the dominant scattering process of the carriers in this system changes from acoustic phonon scattering in PbSe to ionized impurity scattering in AgPbmSnSe2+m, which synergistically optimizes electrical and thermal transport properties. Thanks to the faint amount of AgSnSe2, the Seebeck coefficient is enhanced by boosting the scattering factor, the electric conductivity is improved by the increase of the concentration of holes coupled to a limited degradation of their mobility, and the total thermal conductivity is reduced by suppressing bipolar thermal conductivity. Therefore, ZT of AgPbmSnSe2+m (m = 50) reaches 1.3 at 889 K. The mechanism suggested in this study opens new paths to improve the thermoelectric performances of other families of materials.

description: In a-Si:H/c-Si heterojunction solar cells the UV absorption of amorphous layers limits the current
generation. The use of a more transparent material like a-SiOx:H films is a key to further enhance the efficiency of
this kind of cells. At the same time this layer must guarantee high surface passivation of the c-Si wafer to be suitable
in high efficiency solar cell manufacturing. As for amorphous silicon, thermal annealing procedures are considered as
valuable steps to enhance and stabilize thin film properties, when performed at opportune temperature. In order to
avoid damages of the amorphous layer, each cell fabrication step should be carried at temperature lower than the
emitter formation one. However, when thermal annealing is applied as one of the early fabrication step, the
temperature can be high enough to obtain the best passivation properties. In this work we have analyzed the effect of
several thermal treatments different for temperature, duration and surrounding atmosphere on a-SiOx:H/c-Si/a-SiOx:H
structure. We have fully characterized the samples with the aid of effective lifetime evaluation and FTIR spectra to
correlate the effect of thermal annealing to the a-SiOx:H/c-Si interface.

description: In this thesis we investigate a specific type of semilinear hyperbolic systems with highly oscillatory initial data. This type of systems is numerically very challenging to treat since the solutions are highly oscillatory in space and time. The goal is to derive suitable analytical and numerical approximations. Based on the classical slowly varying envelope approximation (SVEA), an improved error estimate is proven for this analytical approximation. The envelope equation avoids oscillations in space, making this approximation attractive for numerical computations. Furthermore, more accurate analytical approximations are obtained by extending the ansatz of the SVEA. In addition to the analytical study of the SVEA two numerical time integrators are constructed and analyzed without any step-size restrictions. Numerical examples are provided to illustrate the theoretical results. Finally, a complementary approach is presented which address both problems, the oscillations in space and time, simultaneously.

description: Background: Moral Injury (MI) is one of the adverse consequences of combat. Following exposure to potentially morally injurious events (PMIEs)––events perceived as violations of deep moral beliefs by oneself or trusted individuals––a significant minority of veterans could develop posttraumatic stress disorder (PTSD) and depression. Objective: The current study represents the first attempt to apply a network analysis model to examine an exploratory empirical conceptualization of a network of PMIEs during military service, post-traumatic stress disorder (PTSD) symptom clusters, depression, and combat exposure among Israel Defence Forces veterans. Method: A volunteer sample of 191 Israeli combat veterans were recruited during 2017, and completed validated self-report questionnaires tapping PMIEs, PTSD, and depression in a cross-sectional design study. A regularized Gaussian graphical model was estimated. Results: Network analysis revealed strong bridge associations between the PTSD nodes and most of the PMIEs nodes. The nodes of PMIE-betrayal and PTSD negative alterations in cognitions and mood (NACM) symptom cluster were found to have a bridging function between other PMIEs and PTSD. Depression was found to be connected to most of the PMIEs and PTSD nodes. Conclusions: The study’s findings offer an overview of the complex relationships between PMIEs and PTSD clusters among Israeli veterans. PMIEs––notably, betrayal-based experiences––are related to PTSD clusters directly and through depressive symptoms. Some possible mechanisms for the links between PMIEs and PTSD and the clinical implications related to specific interventions are discussed.

description: Isolated long-range interacting particle systems appear generically to relax to non-equilibrium states ("quasi-stationary states" or QSS) which are stationary in the thermodynamic limit. A fundamental open question concerns the "robustness" of these states when the system is not isolated. In this paper we explore, using both analytical and numerical approaches to a paradigmatic one dimensional model, the effect of a simple class of perturbations. We call them "internal local perturbations" in that the particle energies are perturbed at collisions in a way which depends only on the local properties. Our central finding is that the effect of the perturbations is to drive all the very different QSS we consider towards a unique QSS. The latter is thus independent of the initial conditions of the system, but determined instead by both the long-range forces and the details of the perturbations applied. Thus in the presence of such a perturbation the long-range system evolves to a unique non-equilibrium stationary state, completely different to its state in absence of the perturbation, and it remains in this state when the perturbation is removed. We argue that this result may be generic for long-range interacting systems subject to perturbations which are dependent on the local properties (e.g. spatial density or velocity distribution) of the system itself.

description: In this paper, we present the antireflection properties of nanostructured silicon nitride layer formed by
argon treatment of silicon nitride. Significant reduction of reflectance is observed after argon plasma treatment of
silicon nitride layer. Different parameters like power density, gas flow rate, pressure and duration of argon plasma
treatment have been varied to optimize the reflectance of the nanostructured silicon nitride layer. FESEM, FTIR and
reflectance have been performed to study the morphology and optical properties of the silicon nitride layer.
Nanostructures on the surface of the silicon nitride film can be observed in FESEM images. FTIR reveals a change in
Si-N, Si-O and N-H bonds after plasma treatment which indicates a formation of silicon oxynitride layer. The
reduction in reflection may be attributed to the formation of a double layer anti-reflection coating with silicon
oxynitride layer on the top surface which is formed due to argon bombardment and silicon nitride as bottom layer.
Such nanostructured silicon nitride coating can be used as anti-reflection coating on crystalline silicon solar cell, as it
is compatible with present methods of fabrication
