description: We used the Immersion GRating Infrared Spectrometer (IGRINS) to determine fundamental parameters for 61 K- and M-type young stellar objects (YSOs) located in the Ophiuchus and Upper Scorpius star-forming regions. We employed synthetic spectra and a Markov chain Monte Carlo approach to fit specific K-band spectral regions and determine the photospheric temperature ($T_{\rm eff}$), surface gravity ($\log$ g), magnetic field strength (B), projected rotational velocity ($v \sin i$), and K-band veiling ($r_{\rm K}$). We determined B for $\sim$46% of our sample. Stellar parameters were compared to the results from Taurus-Auriga and the TW Hydrae Association (TWA) presented in Paper I of this series. We classified all the YSOs in the IGRINS survey with infrared spectral indices from 2MASS and WISE photometry between 2 and 24~$μ$m. We found that Class II YSOs typically have lower $\log$ g and $v\sin i$, similar B, and higher K-band veiling than their Class III counterparts. Additionally, we determined the stellar parameters for a sample of K and M field stars also observed with IGRINS. We have identified intrinsic similarities and differences at different evolutionary stages with our homogeneous determination of stellar parameters in the IGRINS YSO Survey. Considering $\log$ g as a proxy for age, we found that the Ophiuchus and Taurus samples have a similar age. We also find that Upper Scorpius and TWA YSOs have similar ages, and are more evolved than Ophiuchus/Taurus YSOs.

description: The importance of localised humanitarian responses has recently gained increased international recognition. To date, localisation has been examined primarily from the perspective of international actors, with a particular focus on efforts to improve the efficiency and operational effectiveness of humanitarian assistance. However, the potential of localisation to both strengthen local organisations and health systems, and empower affected communities has not received adequate attention. A better understanding of the challenges faced by local actors working in humanitarian settings could enhance the quality, safety, and sustainability of healthcare for displaced and conflict-affected populations. This scoping review aims to systematically identify and critically examine the emerging literature on localisation in humanitarian health responses.

description: Potential changes in hydro-meteorological events have been causing mass damage to the economy and lives. Among several other factors, the progression of climate change over a long time is expected to cause non-stationarity in annual maximum rainfall. Understanding the characteristics of annual maximum rainfall series is crucial for coastal cities as they are highly vulnerable due to the greatly varying weather patterns. In this paper, we propose stationary and non-stationary methods to model the effect of non-stationarity on the differing duration of annual maximum rainfall and demonstrate the impacts on nine coastal cities spread across the Arabian Sea and Bay of Bengal stretch of India. The Bayesian inference parameter estimation technique was used. It was found that while stationary models often fit well for longer-duration rainfall, non-stationary models often best fit the short duration.

Economic Impact Analysis

description: An economic impact analysis is a methodology that examines the effect of an event on the economy in a specific area. This event that is being analyzed can be anything from a new tax, a new building, or a new business moving into a community. In sports management studies, economic impact is typically viewed as the net economic change in a community that results from spending money on a sports facility, franchise expansion or relocation, sporting event, or any other sports-related expenditure. Thus, a sports-related economic impact analysis is designed to measure the economic benefits of sports-related events to a community. In this article, I will analyze the impact of transitioning a National Collegiate Athletic Association (NCAA) Division II athletic department to NCAA Division I. An overall analysis of the athletic department and the varsity sports it sponsors, conference alignment, and facilities will be provided. A general financial analysis of revenues and expenses that result from this transition will also be reviewed. Finally, I will provide a general recommendation about this transition and briefly review universities that have made this transition.

description: We study the warm-tachyon inflationary universe model with viscous pressure in high-dissipation regime. General conditions which are required for this model to be realizable are derived in the slow-roll approximation. We present analytic expressions for density perturbation and amplitude of tensor perturbation in longitudinal gauge. Expressions of tensor-to-scalar ratio, scalar spectral index and its running are obtained. We develop our model by using exponential potential, the characteristics of this model are calculated for two specific cases in great details: 1- Dissipative parameter $Γ$ and bulk viscous parameter $ζ$ are constant parameters. 2- Dissipative parameter is a function of tachyon field $ϕ$ and bulk viscous parameter is a function of matter-radiation mixture energy density $ρ$. The parameters of the model are restricted by recent observational data from the nine-year Wilkinson microwave anisotropy probe (WMAP9), Planck and BICEP2 data.

description: A method to realize controllable inversion of energy levels in a one-dimensional spin-orbit (SO)-coupled two-component Bose-Einstein condensate under the action of a gradient magnetic field and harmonic-oscillator (HO) trapping potential is proposed. The linear version of the system is solved exactly. By adjusting the SO coupling strength and magnetic-field gradient, the energy-level inversion makes it possible to transform any excited state into the ground state. The full nonlinear system is solved numerically, and it is found that the results are consistent with the linear prediction in the case of the repulsive inter-component interaction. On the other hand, the inter-component attraction gives rise to states of superposition and edge types. Similar results are also reported for the system with the HO trap replaced by the box potential. These results suggest a possibility to realize any excited state and observe it in the experiment.

description: Diagnosis of the salvini clade based on the worker caste The workers of the salvini clade lack a singular diagnostic feature, but can be diagnosed with the following combination of characters: 1. Antennae composed of 12 antennomeres. 2. Postpetiole moderately to very broad: 1.4 to 3 times as broad as the caudal cylinder in dorsal view (PWI 140-300); if less than 1.5 times, then antennal scapes are moderately short, failing to reach the posterior margin of the head by the maximum width of the antennal scape or less, and dorsum of propodeum lacks standing setae. 3. Anterodorsal region of petiole with or without tubercles that are united by a transverse carina; if tubercles present, then median lobe of clypeus bearing many (> 3) fine carinae, femora incrassate (FI> 250), or, if femora not incrassate, then dorsum of propodeum lacks standing setae. 4. Propodeum bearing teeth or spines; or, if propodeum is unarmed, then propodeum is strongly depressed below the level of the evenly convex promesonotum. 5. Legs usually without long tapering setae, but if present, then medial lobe of clypeus bearing many (> 3) longitudinal carinae, or propodeum is strongly depressed below the level of the evenly convex promesonotum.

description: An isotope-enabled module of Hydrus-1D was applied to a potted olive tree to trace water parcels originating from 26 irrigation events in a glasshouse experiment. The soil hydraulic parameters were optimized via inverse modelling by minimizing the discrepancies between observed and simulated soil water content and soil water isotope (18O) values at three soil depths. The model’s performance was validated with observed sap flow z-scores and xylem water 18O. We quantified the source and transit time of irrigation water by analysing the mass breakthrough curves derived from a virtual tracer injection experiment. On average, 26% of irrigation water was removed by plant transpiration with a mean transit time of 94 hours. Our proof of concept work suggests that transit time may represent a functional indicator for the uptake of irrigation water in agricultural ecosystems.

Near-junction cooling of GaN HEMT by capped diamond heat spreader and embedded microchannels
Creators: name: Zhang, Hang
Publisher: name: No Publisher Supplied
Year: 2022

description: Gallium nitride (GaN) high-electron-mobility-transistors (HEMTs) are designed to operate at increasing higher power density and frequency to suit specific applications in 5G communication and electric vehicles. Proper thermal management methods are required to ensure the power density output and long-term reliability of GaN HEMTs. The non-uniformly distributed high die-level heat flux (> 1 kW/cm²) coupled with microscale hotspots has imposed significant thermal management challenges, overshadowing traditional “remote” cooling methods. This dissertation aims to explore two novel “near-junction” cooling techniques. The first one is a capped diamond heat spreader used to facilitate the spreading of heat from hotspot to die. The second is embedded manifold microchannels which quickly remove the heat from the die to the ambient by convection. Firstly, the thermal impacts of capping a diamond layer on multi-finger GaN HEMTs have been investigated under steady-state operation conditions. The scale of temperature reduction highlighted the applicability of the capped diamond spreader as a promising cooling strategy. Secondly, a further study was carried out for diamond heat spreader on a commercial 380-gates GaN-based power amplifier with kW peak power-level under periodic pulse-operated conditions. A scale-down model has been built to enable practical modeling for pulse mode calculation, which can significantly reduce the computational time while maintaining dynamic peak temperature. To precisely evaluate the cooling performance, thickness dependence and anisotropy of micrometer-sized diamond thermal conductivity were considered through two proposed fitted formulas based on experimental data in the literature. The capped diamond cooling strategy is shown to be more effective under harsh thermal conditions, including smaller duty cycle, higher interfacial thermal resistance, and substrate of lower thermal conductivity. Thirdly, an embedded manifold microchannel cooling (EMMC) arrangement was presented, in which microchannels were directly etched in the GaN substrate in close proximity to hotspots. A unit-cell model is built in which a single transistor is coupled with a microchannel beneath, mimicking a recently reported GaN power converter with EMMC arrangement. The single-phase laminar flow of deionized water through near-junction microchannels has been extensively investigated in the unit-cell. The effects of geometrical parameters of the manifold and microchannel, heat flux and flow rate on the thermal-hydraulic performance of the unit-cell were thoroughly studied. Finally, the capped diamond heat spreader was combined with the EMMC to cool the GaN device for the first time.

description: Mutual events (MEs) are eclipses and occultations among planetary natural satellites. Most of the time, eclipses and occultations occur separately. However, the same satellite pair will exhibit an eclipse and an occultation quasi-simultaneously under particular orbital configurations. This kind of rare event is termed as a quasi-simultaneous mutual event (QSME). During the 2021 campaign of mutual events of jovian satellites, we observed a QSME between Europa and Ganymede. The present study aims to describe and study the event in detail. We observed the QSME with a CCD camera attached to a 300-mm telescope at the Hong Kong Space Museum Sai Kung iObservatory. We obtained the combined flux of Europa and Ganymede from aperture photometry. A geometric model was developed to explain the light curve observed. Our results are compared with theoretical predictions (O-C). We found that our simple geometric model can explain the QSME fairly accurately, and the QSME light curve is a superposition of the light curves of an eclipse and an occultation. Notably, the observed flux drops are within 2.6% of the theoretical predictions. The size of the event central time O-Cs ranges from -14.4 to 43.2 s. Both O-Cs of flux drop and timing are comparable to other studies adopting more complicated models. Given the event rarity, model simplicity and accuracy, we encourage more observations and analysis on QSMEs to improve Solar System ephemerides.

description: We study the statistical property of fast radio bursts (FRBs) based on a selected sample of 190 one-off FRBs in the first CHIME/FRB catalog. Three power law models are used in the analysis, and we find the cumulative distribution functions of energy can be well fitted by bent power law and thresholded power law models. And the distribution functions of fluctuations of energy well follow the Tsallis $q$-Gaussian distribution. The $q$ values in the Tsallis $q$-Gaussian distribution are constant with small fluctuations for different temporal scale intervals, indicating a scale-invariant structure of the bursts. The earthquakes and soft gamma repeaters show similar properties, which are consistent with the predictions of self-organized criticality systems.

description: Turbulence is ubiquitous in the interstellar medium (ISM) of the Milky Way and other spiral galaxies. The energy source for this turbulence has been much debated with many possible origins proposed. The universality of turbulence, its reported large-scale driving, and that it occurs also in starless molecular clouds, challenges models invoking any stellar source. A more general process is needed to explain the observations. In this work we study the role of galactic spiral arms. This is accomplished by means of three-dimensional hydrodynamical simulations which follow the dynamical evolution of interstellar diffuse clouds (100cm-3) interacting with the gravitational potential field of the spiral pattern. We find that the tidal effects of the arm's potential on the cloud result in internal vorticity, fragmentation and hydrodynamical instabilities. The triggered turbulence result in large-scale driving, on sizes of the ISM inhomogeneities, i.e. as large as 100pc, and efficiencies in converting potential energy into turbulence in the range 10 to 25 percent per arm crossing. This efficiency is much higher than those found in previous models. The statistics of the turbulence in our simulations are strikingly similar to the observed power spectrum and Larson scaling relations of molecular clouds and the general ISM. The dependency found from different models indicate that the ISM turbulence is mainly related to local spiral arm properties, such as its mass density and width. This correlation seems in agreement with recent high angular resolution observations of spiral galaxies, e.g. M51 and M33.

Privacy-preserving risk assessment and access control in smart buildings

description: In the past two years, the pandemic has shown its severity and infectivity to the world. Although researchers have put a lot of effort into preventing and diminishing the spread of the pandemic, the current situation is gloomy. As a result, more and more companies and institutes offer remote working environments for their employees and students. However, remote working is only a temporary solution as it causes inefficiency and difficulties in coordinating workers, and everyone will go back to classrooms and offices in one day. Therefore, the key to returning to pre-pandemic life is that people need to control the risk of exposing themselves to viruses. In this thesis, we address practical challenges that block the way of implementing indoor risk assessment and access control in privacy-preserving manners. First, data regarding positive infections are sensitive, and they should remain private. Therefore, it is challenging to track users' activities while keeping them secrete for any third-party service provider. Second, since access control needs infection data and biometric data in some cases, the access control system should also be privacy-preserving. In other words, the main access control system should not know the current user's identity and the authentication result to prevent potential privacy leaks. In Chap2, we propose a novel framework for privacy-preserving access control framework and group facial authentication system. Furthermore, in Chap3, we propose a novel privacy-preserving risk assessment framework with Federated Learning (FL). Last but not least, in Chap4, we developed an Android application to show the practicality of the framework proposed in Chap3.

description: Topological edge states form at the edges of periodic materials with specific degeneracies in their modal spectra, such as Dirac points, under the action of effects breaking certain symmetries of the system. In particular, in Floquet topological insulators unidirectional edge states appear upon breakup of the effective time-reversal symmetry due to dynamical modulations of the underlying lattice potential. However, such states are usually reported for certain simple lattice terminations, for example, at zigzag or bearded edges in honeycomb lattices. Here we show that unconventional topological edge states may exist in Floquet insulators based on arrays of helical waveguides with hybrid edges involving alternating zigzag and armchair segments, even if the latter are long. Such edge states appear in the largest part of the first Brillouin zone and show topological protection upon passage through the defects. Topological states at hybrid edges persist in the presence of focusing nonlinearity of the material. Our results can be extended to other lattice types and physical systems, they lift some of the constraints connected with lattice terminations that may not support edge states in the absence of effects breaking time-reversal symmetry of the system and expand the variety of geometrical shapes in which topological insulators can be constructed.

The effects of Mental and Physical (MAP) Training on teacher stress and well-being during the COVID-19 pandemic: a pilot study
Creators: name: Demmin, Docia L.
Publisher: name: No Publisher Supplied

description: Teachers experience significant job-related stress that can lead to burnout and attrition. Existing teacher stress may have been increased as a result of the COVID-19 pandemic. Thus, interventions to target stress and promote mental health and wellbeing may benefit this population. Mental and Physical (MAP) Training combines meditation with aerobic exercise to improve mental and physical health outcomes. This pilot study aimed to evaluate the effectiveness of virtual MAP Training on reducing stress and improving outcomes in teachers. K-12 educators were recruited from schools in the Northeastern region of the United States. Participants were randomly assigned to the MAP Training group (n = 35) or waitlist control condition (n = 13). The effects of the virtual MAP Training program on self-reported psychosocial, cognitive, and health outcomes were examined after six weeks. The long-term impact of training (i.e., one month after intervention end) was investigated in exploratory analyses. There were no significant differences between groups in pre-intervention (i.e., baseline) or post-intervention ratings of psychosocial, cognitive, or health functioning. However, participants within the MAP Training group reported significant improvements in trauma and mood symptoms (ps = .001-.004, ds = .53-.66), anxiety symptoms (p = .002, d = .57), ruminative thinking (ps = .003-.016, ds = .43-.54), perceived stress (p = .035, d = .38), and self-compassion (p < .001, d = -.82), while no significant changes were observed within the waitlist control group. Participants within the MAP Training group also reported improvements in executive functioning and cognitive flexibility (ps = < .001 - .023, ds = -.41-.94) and fewer sleep disturbances (p = .002, d = .57) following training, while again no within-group changes were observed among waitlist control participants. Among MAP Training participants, 24% experienced a clinically significant reduction in depressive symptom severity, while 31% reported meaningful change in anxiety symptom severity. Outcomes did not differ between treatment adherent (i.e., attended four or more live training sessions) and non-adherent MAP Training participants; however, adherence factors were associated with greater improvement in executive functioning. Importantly, improvements in self-compassion were maintained by MAP Training participants one month after intervention end. These data demonstrate the effectiveness of a virtually-delivered meditation and aerobic exercise program (i.e., MAP Training) in improving teacher mental health and well-being during the COVID-19 pandemic.

description: When faculty members assume academic leadership roles, they are often expected to possess the competencies necessary for effective leadership. However, faculty members at academic health centers (AHCs) are prepared to specialize in careers pertaining to research, education, patient care, and service – not leadership – and so, they may be underprepared for such roles (Ruben et al., 2017). Fortunately, there are various leadership development interventions that can support faculty in preparing to serve in formal leadership positions, and one such intervention is participating in a leadership development program (LDP). Despite their popularity, LDPs are frequently critiqued regarding their effectiveness to develop leaders (Avolio, 2010; Kellerman, 2012) likely due at least in part to limited research focused on leadership development and a lack of theory-informed practice. The majority of AHC LDPs do not report using any guiding framework (Lucas et al., 2018; Moore Simas et al., 2019), suggesting there may be instances where development may be assumed and left to chance rather than systematically incorporated into the design, delivery, and assessment of LDPs.This qualitative case study examined the experiences of faculty leaders participating in an AHC LDP to determine what development may have occurred and how the program may have facilitated it. This research study utilized interviews and document analysis of participants’ reflective writing responses to explore their leadership development. Guided by a conceptual model that integrates learning and leadership theories, leadership development is understood as involving cognitive, behavioral, and affective learning applied at individual, relational, and organizational levels. The findings of this study resulted in a framework that identifies various developmental processes involved in an LDP and discusses the program components that participants associated with such development. In addition, the complexity of leadership development is depicted comprehensively in an integrative framework that summarizes the multiple factors involved in leadership development as it relates to participating in an LDP. This study contributes to research of faculty leadership development and how LDPs may be effective interventions in facilitating developmental processes.

description: Land use is a driver for hydrological and soil erosion responses at the watershed scale. This study aimed to assess the hydrological and soil erosion processes in small watersheds under three different land uses, at three time scales. We investigated four small watersheds in southern Brazil: Agricultural North watershed (ANW), Agricultural South watershed (ASW), Eucalyptus watershed (EW), and Grassland watershed (GW). The SWAT (Soil and Water Assessment Tool) model was used to simulate streamflow (SF) and sediment yield (SY) at monthly, daily and hourly time scales. EW had the lowest SF and SY, whereas ANW showed the highest SY with an increase of 90% and ASW had the highest SF with an increase of 70%. The SWAT model had a satisfactory performance in all time scales and watersheds for SF and SY (NSE and R2 ≥ 0.3 and Pbias ≤ ± 39%). Overall, land use has a major impact on hydrological and soil erosion responses, and the magnitude of these processes depends on the time scale.

description: The paper presents a straightforward modelling approach to compute the power loss distribution in GaN HEMT based three phase and three level (3L) active neutral point clamped (ANPC) inverters, for different pulse width modulated techniques. Conduction and switching losses averaged over each PWM switching period are analytically computed by starting from the operating conditions of the AC load and data of GaN power devices. The accuracy of the proposed analytical approach is evaluated through a circuit based power electronics simulation tool, applied to different carrier-based PWM strategies.

description: Background: Significant gaps exist in understanding the relationship between patients’ attitudes towards methadone, social determinants of health (SDOH), substance use factors as indicators of perceived behavioral control (PBC), and the intention to remain in methadone treatment. This study examined the influence of methadone attitudes and assessed the interaction effects of SDOH among people who use opioids (PWUO) in New Jersey substance use clinics. The effects of substance use factors on the intention to remain in methadone treatment among this population were also explored. Methods: Utilizing data from the “New Jersey Opioid Overdose Study,” generalized linear regression and a series of simple moderation analyses were used to assess the main and interaction effects of methadone attitudes and SDOH on the intention to remain in methadone treatment. Multiple linear regression analyses were used to examine the predictor effects of substance use factors on intention to remain in methadone treatment. Results: Survey responses from 290 participants were analyzed in the study. Positive methadone attitudes were significantly associated with the intention to remain in methadone treatment (p<.001). SDOH, including ethnicity, employment status, and marital status, revealed a significant interaction relationship with methadone attitudes and intention to remain in methadone treatment (p=0.013, p=0.025, and p<.001, respectively). The intention to remain in methadone treatment increased as positive attitudes toward methadone increased for non-Hispanic, full-, part-time, and unemployed participants. Marital status (married/ever married and never married) also positively enhanced the relationship between positive methadone attitudes and intention to remain in methadone treatment. Multiple linear regression indicated that prior methadone and buprenorphine treatment (p=0.004) and positive methadone attitudes (p<.001) had significant positive associations with intention to remain in methadone treatment. Negative associations existed between heavy smoking (smoking a pack of cigarettes or more per day), opioid use in the last 30 days (p=0.003 and p=0.009, respectively), and intention to remain in methadone treatment. Conclusions: Methadone attitudes, substance use factors, and SDOH shape intention to remain in methadone treatment. Assessing factors influencing intention can aid in supporting patients' goals of remaining in methadone treatment. Healthcare providers and policymakers can use these associations to implement targeted interventions, particularly for diverse and underserved PWUO, and address issues related to methadone retention.

description: Potential changes in hydro-meteorological events have been causing mass damage to the economy and lives. Among several factors, the progression of climate change over a long time is expected to cause the non-stationarity in annual maximum rainfall. Understanding the characteristics of annual maximum rainfall series is crucial for coastal cities as they are highly vulnerable due to the largely varying weather patterns. In this paper, we propose stationary and non-stationary methods to model the effect of non-stationarity on the different duration of annual maximum rainfall and demonstrate the impacts on nine coastal cities spread across the Arabian and Bay of Bengal sea stretch of India. The Bayesian Inference parameter estimation technique was used. It was found that while stationary models have been often found to fit well for longer-duration rainfall, non-stationary models have been often observed to best fit the short duration.

description: An isotope-enabled module of Hydrus-1D was applied to a potted olive tree to trace water parcels originating from 26 irrigation events in a glasshouse experiment. The soil hydraulic parameters were optimised via inverse modelling by minimising the discrepancies between observed and simulated soil water content and soil water isotope (δ18O) values at three soil depths. The model’s performance was validated with observed sap flow z-scores and xylem water δ18O. We quantified the source and transit time of irrigation water by analysing the mass breakthrough curves derived from a virtual tracer injection experiment. On average, 26 % of irrigation water was removed by plant transpiration with a mean transit time of 94 hours. Our proof of concept work suggests that transit time may represent a functional indicator for the uptake of irrigation water in agricultural ecosystems.

description: Optically-detected magnetic resonance using Nitrogen Vacancy (NV) color centres in diamond is a leading modality for nanoscale magnetic field imaging, as it provides single electron spin sensitivity, three-dimensional resolution better than 1 nm, and applicability to a wide range of physical and biological samples under ambient conditions. To date, however, NV-diamond magnetic imaging has been performed using real space techniques, which are either limited by optical diffraction to 250 nm resolution or require slow, point-by-point scanning for nanoscale resolution, e.g., using an atomic force microscope, magnetic tip, or super-resolution optical imaging. Here we introduce an alternative technique of Fourier magnetic imaging using NV-diamond. In analogy with conventional magnetic resonance imaging (MRI), we employ pulsed magnetic field gradients to phase-encode spatial information on NV electronic spins in wavenumber or k-space followed by a fast Fourier transform to yield real-space images with nanoscale resolution, wide field-of-view (FOV), and compressed sensing speed-up.
