On commuting transfer matrices

We study the non-singular Ä-matrices of the 8 vertex model satisfying the free Fermion condition, with a generalization that we allow non symmetric off diagonals. Using the result shown in another paper that the transfer matrix T constructed from each such i? -matrix commutes with a class of XYh-type Hamiltonian (somewhat generalized, and not necessarily selfadjoint), we show that such T-matrices commuting with each fixed Hamiltonian commute with each other at least for generic values of parameters. In terms of the (Fermion) Clifford algebra obtained by the Jordan-Wigner transformation, the transfer matrix X for a generic value of parameters is shown to coincide with a constant multiple of elements of the group Spin (2N, C) when multiplied by even and odd particle number projection operator.
Do Values Predict Socially Responsible Investment Decisions? Measuring the Moderating Effects of Gender

This study examines investors’ pro-environmental investment intentions by measuring the effect of economic concern (egoistic value) and environmental concern (altruistic value) on attitudes toward socially responsible investment (SRI). A self-administered structured questionnaire was used to collect data from 469 investors using a purposive sampling technique and analyzed using two-step structural equation modeling. Results show that both altruistic and egoistic values were significant predictors of a positive attitude toward SRI, portraying the greater environmental concern of investors. Additionally, male investors motivated to invest in SRI are more concerned about environmental well-being than their counterparts, that is, female investors. By analyzing values as antecedents of attitudes toward SRI, the findings of this study add a new dimension to the belief system of young investors. JEL Codes: A13; D19; G1; G4
Analysis and Design of a Self-Powered VEH System Based on ULP Comparator

The study conducted addresses a vibrational energy harvester (VEH) based on a microelectromechanical system (MEMS) with a gap-closing electrostatic resonator. The harvester consists of a charge pump system in the form of a rectifier with feedback with an ultra-low-power (ULP) comparator as output. The latter regulates the harvesting cycle of the system using a bulk-driven topology. The complete circuit is implemented in a 180 nm silicon technology. The designed energy harvester generates an output power of 65.45nW at an acceleration of $\boldsymbol{0.35m/s^{2}}$ and a frequency of 53.5Hz. The implemented circuit is supplied with a voltage of one volt and has an average power consumption of 7nW in the operating range. All simulations were conducted using Cadence Virtuoso.
Providing 3D Guidance and Improving the Music-Listening Experience in Virtual Reality Shooting Games Using Musical Vibrotactile Feedback

In this study, we aim to improve the experience of virtual reality (VR) shooting games by employing a 3D haptic guidance method using necklace-type and belt-type haptic devices. Such devices help to modulate the vibrations generated by and synchronized with musical signals according to the azimuth and height of a target in 3D space, which is expected to improve the gaming experience by providing 3D guidance and enhancing the music-listening experience. For the first step, we evaluated the method's potential by conducting an experiment in which participants were asked to shoot a randomly spawned target moving in 3D VR space. The experiment applied four conditions: the proposed method (Haptic), displaying 3D radar (Vision) to represent the visualization method, no guidance (None), and a combination of Haptic and Vision (VisHap). Outcomes related to the success rate and accomplishment time (of the shooting task), the number of head rotations, and participant responses to a follow-up questionnaire revealed that Haptic performed significantly better than None but was inferior to Vision, indicating that the proposed method succeeded in terms of effectively providing 3D guidance. VisHap performed roughly as well as Vision and was preferred to other conditions in most cases, indicating the general usefulness of the proposed method. Meanwhile, the findings from the questionnaire suggest that although the modular vibrations improved the music-listening experience during the shooting task, the impact on the overall gaming experience is unclear. This warrants further research.
Comparison of methods for achieving induced transparency or absorption with pulse delay or advancement in a single microresonator

Induced transparency and absorption effects can be observed in the throughput of an optical microresonator that has two coresonant modes with very different quality factors. There are several different methods for achieving these effects, which enable slow light and fast light, i.e., the delay or advancement of an incident resonant pulse. For example, mode coupling can be employed. This coupling can take place between modes of the same polarization or modes of orthogonal polarization. Another method is based on superposition, when two orthogonally polarized modes are driven simultaneously by linearly polarized input light and throughput of the same polarization as the input is detected. In general, induced transparency is accompanied by pulse delay, whereas induced absorption can be accompanied by pulse advancement or delay. A number of different methods for producing induced transparency or absorption are compared here. Several properties are considered for comparison. One involves the widths of the induced transparency or absorption window and of the corresponding spectral region of steep dispersion. Achievable pulse delays or advancements, along with pulse distortion and delay-bandwidth (or advancement-bandwidth) products, are also compared. Different methods allow for different amounts of control over various system parameters, and these are compared as well. The differences among the several methods are evaluated in consideration of suitability for employment in various applications.
Neural Responses to a Working Memory Task in Acute Depressed and Remitted Phases in Bipolar Patients

(1) Cognitive impairments such as working memory (WM) deficits are amongst the most common dysfunctions characterizing bipolar disorder (BD) patients, severely contributing to functional impairment. We aimed to investigate WM performance and associated brain activation during the acute phase of BD and to observe changes in the same patients during remission. (2) Frontal brain activation was recorded using functional near-infrared spectroscopy (fNIRS) during n-back task conditions (one-back, two-back and three-back) in BD patients in their acute depressive (n = 32) and remitted (n = 15) phases as well as in healthy controls (n = 30). (3) Comparison of BD patients during their acute phase with controls showed a trend (p = 0.08) towards lower dorsolateral prefrontal cortex (dlPFC) activation. In the remitted phase, BD patients showed lower dlPFC and ventrolateral prefrontal cortex (vlPFC) activation (p = 0.02) compared to controls. No difference in dlPFC and vlPFC activation between BD patients’ phases was found. (4) Our results showed decreased working memory performance in BD patients during the working memory task in the acute phase of disease. Working memory performance improved in the remitted phase of the disease but was still particularly attenuated for the more demanding conditions.
MM5 Ensemble Mean Precipitation Forecasts in the Taiwan Area for Three Early Summer Convective (Mei-Yu) Seasons

Abstract This study presents precipitation verification of individual members and ensemble means in the Taiwan area for a real-time mesoscale ensemble prediction system, during the 2000, 2001, and 2002 early summer convective (mei-yu) seasons. The ensemble system, using the fifth-generation Pennsylvania State University–NCAR Mesoscale Model (MM5) as a forecast model, consists of six members, each run with a different combination of moisture physics schemes. Precipitation forecasts within the 15-km domain were verified against the observational data from the 342 rain gauge stations on the island. In general the model that utilized the Grell cumulus parameterization scheme (CPS) and the Reisner I microphysics scheme (the GR model) had the best forecast skill among the six members. This physics combination is, therefore, recommended for MM5 rainfall simulations in the Taiwan area during the mei-yu season. The Kain–Fritsch CPS dominated the rainfall process and generally underforecast rainfall at high rainfal.
The Nexus Between High-Involvement Work Practices and Employees’ Proactive Behavior in Public Service Organizations: A Time-Lagged Moderated-Mediation Model

Purpose Public service organizations may improve the quality of services they offer citizens by instilling proactive behavior in their employees. This study aimed to provide insights on how high-involvement work practices may indirectly facilitate proactive behavior in frontline government employees via employee commitment. Methods A time-lagged approach was used to collect data from 542 frontline employees in three waves at 3-week intervals. We tested the hypothesized moderated mediation model using a PROCESS macro bootstrap approach. Results A moderated-meditation model was applied in which public service motivation was theorized to increase the mediating effect of employee commitment on the relationship between high-involvement work practices and employee proactive behavior. As predicted, the findings show that supervisor’ deviant behavior attenuated the mediating effect of employee commitment on the relationship between high-involvement work practices and employee proactive behavior. Conclusion The findings of this research contribute to the emerging literature on public management and have implications for public sector organizations seeking to improve the quality of services they offer citizens.
Development of English in Marathi Speaking Children Attending English Medium Schools (Senior Kindergarten and Grade I)

An increasing number of Marathi-speaking children attend English medium schools in Maharashtra, India. The developmental trend of English in these children is not studied according to the researcher’s best knowledge. Studying this development is essential to understand the development of children with developmental disabilities. Hence, the study aimed to understand the development of English in Marathi-speaking children attending English medium schools in senior kindergarten and Grade I (5 to 7 years of age). Forty Marathi-speaking children attending English medium schools (Senior Kindergarten and Grade I) were included. ‘Clinical Evaluation of Language Fundamentals Preschool 2nd Edition (CELF)’ was used to assess children's language skills, and ‘Development of Emergent Literacy- Questionnaire’ was administered to study the relation between home literacy environment and language skills in English. A gender difference was present for Senior Kindergarten children but not for the children studying in Grade I. More than 65% of children had scores below the age equivalent scores across the subtests. A moderate positive correlation was found between all the subtests of CELF and the score on the emergent literacy questionnaire. In conclusion, there is an effect of gender on English language skills in kindergarten which is not present in Grade I. The competency in English in Marathi-speaking children appears to be low and moderately related to literacy exposure at home.
Auxetic composites made of 3D textile structure and polyurethane foam

Auxetic composites have attracted considerable attention in recent years and have demonstrated a high potential of applications in different areas due to their wonderful properties as compared to non‐auxetic composites. In this study, a three‐dimensional (3D) auxetic textile structure previously developed was used as reinforcement to fabricate auxetic composites with conventional polyurethane (PU) foam. Both the deformation behavior and mechanical properties of the auxetic composites under compression were analyzed and compared with those of the pure PU foam and non‐auxetic composites made with the same materials and structural parameters but with different yarn arrangement. The results show that the negative Poisson's ratio of composites can be obtained when suitable yarn arrangement in a 3D textile structure is adopted. The results also show that the auxetic composites and non‐auxetic composites have different mechanical behaviors due to different yarn arrangements in 3D textile structure. While the auxetic composites behave more like damping material with lower compression stress, the non‐auxetic composite behaves more like stiffer material with higher compression stress. It is expected that this study could pave a way to the development of innovative 3D auxetic textile composites for different potential applications such as impact protection.
Bilinear Control Based on Model Bias Separation for Uncertain Nonlinear Systems

Nonlinearity and uncertainty are the main factors which restrict the system performance. There are many methods to attempt to overcome the impact of these factors. A bilinear control strategy based on model bias separation is proposed in this paper. The bilinear control obtains the model bias information on line, and adopts a simple bilinear control structure. So it has good engineering significance. The sufficient condition for system exponential stability has been proved. The simulation results show the effectiveness of the proposed bilinear control strategy.
A Tailored mHealth App for Improving Health and Well-Being Behavioral Transformation in UK Police Workers: Usability Testing via a Mixed Methods Study

Background When considering the policing environment of 2022, many roles previously in the domain of warranted officers (police officer) are now performed by nonwarranted police staff equivalents. These police staff roles have expanded rapidly into other areas such as investigations, custody, and contact management, which were traditionally seen as police officer functions and put staff under some of the same stresses as police officers. A UK police force requested help in investigating technologies that could be used to improve health and well-being for both officers and staff. Objective The aim of this study was to create a health and well-being app for police officers and staff, which considered the unique requirements of the users throughout the designing, building, prototyping, and testing stages. Methods This study involved quantitative approaches (demographic web-based survey questions and the System Usability Scale) and qualitative approaches (open web-based survey questions and semistructured interviews). Unsupervised usability testing of a prototype app was undertaken by members (N=48) of the commissioning client using their smartphones. After completing a preregistration application for screening purposes, participants downloaded a trial version of the app. Then, they completed a web-based questionnaire after testing the app for 10 days. A subsample of participants (9/48, 19%) was interviewed. Deductive thematic analysis was undertaken to identify key themes and subthemes. Results Data collected during usability testing concerned the 6 domains of the app—food and diet, activity, fluid intake, sleep, good mental health, and financial well-being—and informed the creation of improved design during prototyping. Some usability and design issues and suggestions for improvements were also addressed and implemented—including shift management and catch-up cards—during this cycle of development. Conclusions This study highlights the importance of coparticipation with officers and staff across the entire development cycle, to coproduce a human-centered design methodology to enable the development of a considered and user-centered solution. It demonstrates the need for producing a multifunctional tool rather than focusing purely on an individual element for this user group. It also highlights how linking and being able to track optional, personalized elements of health data against one another, cross-referenced to individual shift patterns, might help to inform and provide users with a chance for reflection and therefore influence behavior change.
Business network power as a process for enhancing firm performance: A perspective of RAToC

Abstract This study aims to bridge the gap in inconsistent findings on the use of social media technology to enhance firm performance through business network power and market entry speed. The original premise of this study is the formulation of business network power, derived from the resource advantage theory of competition, through social media as a primary process that impacts a firm’s performance. Data were collected from a sample of 236 owner—managers of small-to-medium craft subsector enterprises in the creative industry in Bali, Indonesia. The results indicate that social media can be a primary trigger for leveraging business network power and strengthening market entry speed and performance. This study has several theoretical and managerial implications.
MAXI J1848-015: The First Detection of Relativistically Moving Outflows from a Globular Cluster X-Ray Binary

Over the past decade, observations of relativistic outflows from outbursting X-ray binaries in the Galactic field have grown significantly. In this work, we present the first detection of moving and decelerating radio-emitting outflows from an X-ray binary in a globular cluster. MAXI J1848−015 is a recently discovered transient X-ray binary in the direction of the globular cluster GLIMPSE-C01. Using observations from the Karl G. Jansky Very Large Array, and a monitoring campaign with the MeerKAT observatory for 500 days, we model the motion of the outflows. This represents some of the most intensive, long-term coverage of relativistically moving X-ray binary outflows to date. We use the proper motions of the outflows from MAXI J1848−015 to constrain the component of the intrinsic jet speed along the line of sight, βintcosθejection , to be =0.19 ± 0.02. Assuming it is located in GLIMPSE-C01, at 3.4 kpc, we determine the intrinsic jet speed, β int = 0.79 ± 0.07, and the inclination angle to the line of sight, θ ejection = 76° ± 2°. This makes the outflows from MAXI J1848−015 somewhat slower than those seen from many other known X-ray binaries. We also constrain the maximum distance to MAXI J1848−015 to be 4.3 kpc. Finally, we discuss the implications of our findings for the nature of the compact object in this system, finding that a black hole primary is a viable (but as-of-yet unconfirmed) explanation for the observed properties of MAXI J1848−015. If future data and/or analysis provide more conclusive evidence that MAXI J1848−015 indeed hosts a black hole, it would be the first black hole X-ray binary in outburst identified in a Galactic globular cluster.
Estimated effects of amyloid reduction on cognitive change: A Bayesian update across a range of priors

Abstract INTRODUCTION The results of the CLARITY‐AD, GRADUATE I and II, and TRAILBLAZER‐ALZ 2 trials have rekindled discussion on the impact of amyloid‐targeting drugs. We use a Bayesian approach to quantify how rational observers would have updated their prior beliefs based on new trial results. METHODS We used publicly available data from the CLARITY‐AD, GRADUATE I and II, and TRAILBLAZER‐ALZ 2 trials to estimate the effect of reducing amyloid on the clinical dementia rating scale, sum of boxes (CDR‐SB) score. A range of prior positions were then updated according to Bayes’ theorem using these estimates. RESULTS After updating with new trial data, a wide range of starting positions resulted in credible intervals that did not include no effect of amyloid reduction on CDR‐SB score. DISCUSSION For a range of starting beliefs and assuming the veracity of the underlying data, rational observers would conclude there is a small benefit of amyloid reductions on cognition. This benefit must be weighed against opportunity cost and side‐effect risk. Highlights The results of recent trials of amyloid‐targeting drugs have rekindled discussion on the impact of amyloid reductions achieved with amyloid‐targeting drugs on cognition. Prior to the announcement of trial results, beliefs about the effects of altering amyloid levels varied. For a range of starting beliefs, one would conclude there is a small benefit of amyloid reductions due to amyloid‐targeting drugs on cognition. The perceived value of individual drugs must balance the magnitude of this benefit against opportunity cost and risk of side effects.
A Liouville comparison principle for solutions of quasilinear singular parabolic inequalities

Abstract We obtain a Liouville comparison principle for entire weak solutions (u,v) of quasilinear singular parabolic second-order partial differential inequalities of the form u t -A(u)-|u| q-1 u≥v t -A(v)-|v| q-1 v${ u_t - A(u)-|u|^{q-1}u \ge v_t - A (v)-|v|^{q-1}v }$ on the set 𝕊 τ =(τ,+∞)×ℝ n ${{\mathbb {S}}_{\tau }= (\tau , +\infty )\times {\mathbb {R}}^n}$ , where q > 0, n ≥ 1, τ is a real number or τ=-∞${\tau =-\infty }$ , and the differential operator A satisfies the α-monotonicity condition. Model examples of the operator A in our study are the well-known p-Laplacian operator defined by the relation Δ p (w)=div x (|∇ x w| p-2 ∇ x w)${\Delta _p (w)=\operatorname{div}_x(|\nabla _x w|^{p-2}\nabla _x w) }$ and its well-known modification defined by Δ ˜ p (w)=∑ i=1 n ∂ ∂x i (|∂w ∂x i | p-2 ∂w ∂x i )${ \widetilde{\Delta }_p (w) = \sum _{i=1}^n\frac{\partial }{\partial x_i}( |\frac{\partial w}{\partial x_i}|^{p-2}\frac{\partial w}{\partial x_i})}$ .
Regulatory Effects of the Probiotic Clostridium butyricum on Gut Microbes, Intestinal Health, and Growth Performance of Chickens

ABSTRACT Clostridium butyricum is an important probiotic for chickens and exerts various biological activities, including altering the composition of the intestinal microbiota, competing with other microorganisms for nutrients, improving the integrity of the intestinal mucosal system, changing the intestinal barrier, and improving overall host health. Intestinal microbes also play vital roles in maintaining the intestinal barrier, regulating intestinal health, and promoting chicken growth. During chicken production, chickens are vulnerable to various stressors that have detrimental effects on the intestinal barrier with significant economic consequences. C. butyricum is a known probiotic that promotes intestinal health and produces the short-chain fatty acid butyric acid, which is beneficial for the growth performance of chickens. This review elucidates the development and utilization of C. butyricum to improve intestinal barrier function and growth performance in chickens through its probiotic properties and interactions with intestinal microbes.
