Psychosocial well-being needs of alcohol/drug sufferers and therapeutic architectural solutions in rehabilitation centre, Nigeria: a cross-sectional study
Authors: Ekhaese Eghosa , Ezeora Ifeanyi 
Published: June 2023

Background: In a rehabilitation centre designed for drug and alcohol recovery, the therapeutic environment may enhance the psychosocial well-being of sufferers and facilitate a speedy recovery. This study aims to investigate the psychosocial well-being needs (PWNs) of users in an alcohol and drug rehabilitation centre (ADRC) and how therapeutic architectural solutions (TASs) can promote a healing environment through design. Methods: The study employed a mixed research method (qualitative and quantitative). The research strategy was a case study of four rehabilitation centres in Nigeria’s busiest cities; Lagos, Abuja, Port Harcourt, and Enugu. Data were collected via survey questionnaires, an in-depth interview guide, an observation guide, and a checklist of TACs in a healthcare facility. We first investigated what the PWNs of alcohol and drug sufferers (ADSs) are, then identified the therapeutic architectural components (TACs) of an ADRC, before determining what effect TACs have on the recovery process of substance abuse patients. Results: The findings identify eight PWNs and nine TACs essential in an ADRC. The result indicates that TACs have a significant effect on the recovery process of ADSs. However, based on the study results, a framework (framework here refers to using an intelligent and sensitive conceptual design structure as a standard guide for the building archetype rehabilitation facility, which supports mental health service delivery) may be recommended for rehabilitation facilities with TASs for Substance Abuse Disorder (SUD). Conclusion: The study result presents a correlation between ADSs' recovery rates and a well-designed therapeutic environment. So, there is a need for evidence-based design (EBD) of rehabilitation centres with full compliments of a therapeutic architectural environment and integration of mental health services into routine care in sub-Saharan Africa. Limitations include that analyses were cross-sectional and thus may not deduce causal directions, and the authors based the result on self-report.
Asymptotically Optimal Control of Make-to-Stock Systems
Authors: Gao Xuefeng , Huang Junfei 
Published: June 2023

We consider multiclass make-to-stock production/inventory systems in which the manager makes three decisions, including pricing, outsourcing, and scheduling, to maximize the long-run average profit. For a sequence of systems in the heavy-traffic regime, with linear or strictly convex holding/waiting cost functions, we propose a sequence of policies and establish its asymptotic optimality. Our proof combines the lower bound approach and a thorough steady-state analysis of the systems. We also establish general results on the existence and tightness of the stationary distributions of the state processes under a more general family of policies. Funding: X.

Asymptotic Optimality of Semi-Open-Loop Policies in Markov Decision Processes with Large Lead Times
Authors: Bai Xingyu , Chen Xin , Li Menglong , Stolyar Alexander 
Published: June 2023

A generic way to verify asymptotic optimality of semi-open-loop policies for a wide class of MDPs with large lead times. In many real-life inventory models, order lead times can result in uncertain effects of inventory decisions. However, as the lead time grows large, one would naturally postulate that the effect of the delayed order depends weakly on the current inventory level and, thus, intuit that decoupling the delayed order with the current inventory level may provide good heuristics. Motivated by these examples, in “Asymptotic Optimality of Semi-open-Loop Policies in Markov Decision Processes with Large Lead Times,” Bai et al. consider a generic Markov decision process (MDP) with one delayed control and one immediate control. For MDPs defined on general spaces with uniformly bounded cost functions and a fast mixing property, they construct a periodic semi-open-loop policy for each lead time value and show that these policies are asymptotically optimal as the lead time goes to infinity. For MDPs defined on Euclidean spaces with linear dynamics and convex structures, they impose another set of conditions under which constant delayed-control policies are asymptotically optimal.
The Radical Flank Revisited: How Regulatory Discretion Shapes the Effectiveness of Social Activism on Business Outcomes
Authors: Grandy Jake B. , Hiatt Shon R. 
Published: June 2023

Although scholarship has highlighted how stakeholders can influence business outcomes, few studies have examined how simultaneous, different tactics interact to impact firms. Critical to understanding this interaction is the radical flank effect, which asserts that the moderate and radical elements of social activist tactics can interact to either enhance or diminish a movement’s ability to accomplish its goals. However, research is unclear about when and whether the radical flank effect enhances or diminishes activist influence, nor has it empirically analyzed factors that influence the direction of the effect. To address these limitations, we explore one such factor—regulatory agency discretion, or regulators’ flexibility to interpret and implement public policies. Drawing on management and political sociology studies, we argue that discretion affects the salience of regulatory accountability to the public and thereby alters the radical flank effect on business outcomes in regulated markets. We analyze stakeholder opposition to U.S. hydroelectric power facilities from 1987 to 2019. The results show that high discretion enhances the radical flank effect and detrimentally affects business outcomes, whereas low discretion reverses the radical flank effect and favorably affects business outcomes.

Which Types of Investments Benefit from Retaining the Flexibility to Terminate?
Authors: Chavda Ankur 
Published: June 2023

Firms can choose to make investments while retaining the option to terminate them prior to completion. This flexibility can mitigate uncertainty about the investment that is present at the time of its initial funding. However, this flexibility can also detrimentally alter actions within the firm that are necessary for the investment’s success, such as whether scarce firm resources are allocated to the investment. This paper develops a set of hypotheses which predicts flexibility may not improve investment performance when the investment generates limited early-stage learning and requires certain types of resources. These hypotheses are empirically tested in a data set of new U.S. television programs, comparing programs that receive commitment in the form of a straight-to-series order with programs that are flexibly developed through a piloting process. This paper contributes to the literatures on innovation, entrepreneurship and real options by identifying which investment types will benefit most from flexibility.

Optimally Scheduling Public Safety Power Shutoffs
Authors: Lesage-Landry Antoine , Pellerin Félix , Callaway Duncan S. , Taylor Joshua A. 
Published: June 2023

In an effort to reduce power system-caused wildfires, utilities carry out public safety power shutoffs (PSPSs), in which portions of the grid are deenergized to mitigate the risk of ignition. The decision to call a PSPS must balance reducing ignition risks and the negative impact of service interruptions. In this work, we consider three PSPS scheduling scenarios, which we model as dynamic programs. In the first two scenarios, we assume that N PSPSs are budgeted as part of the investment strategy. In the first scenario, a penalty is incurred for each PSPS declared past the Nth event. In the second, we assume that some costs can be recovered if the number of PSPSs is below N while still being subject to a penalty if above N. In the third, the system operator wants to minimize the number of PSPSs such that the total expected cost is below a threshold. We provide optimal or asymptotically optimal policies for each case, the first two of which have closed-form expressions. Lastly, we establish the applicability of the first PSPS model’s policy to critical peak pricing and obtain an optimal scheduling policy to reduce the peak demand based on weather observations.

Published: June 2023

In this study, we developed a novel, compact, and efficient structured illumination microscopy (SIM) system, to our best knowledge. A binary hexagonal lattice pattern was designed and implemented on a digital micromirror device (DMD), resulting in a projection-based structured-light generation. By leveraging the combination of the high-speed switching capability of the DMD with a high-speed CMOS camera, the system can capture 1024×1024 pixels images at a 200 fps frame rate when provided with sufficient illumination power. The loading of the hexagonal lattice pattern reduces the number of images required for reconstruction to seven, and by utilizing the DMD modulating characteristics on the illumination path, there is no need to use bulky mechanical structures for phase shifting. We designed a compact system with 110mm×150mm×170mm dimensions that displayed a 1.61 resolution enhancement for fluorescent particle and biological sample imaging.
Interferometric measurement of the radius of curvature based on axial displacement from a confocal position and corresponding defocus wavefront

Published: June 2023

The radius of curvature (R) is a fundamental parameter of
spherical optical surfaces. The measurement range of the widely
adopted traditional interferometric method is limited by the length of
the precision linear guide rail carrying the measured surface from the
cat’s eye to the confocal position, and the test result is vulnerable
to airflow and vibration in the test environment. An interferometric
method is proposed for the radius measurement of spherical surfaces
based on a small axial moving distance and the corresponding defocus
wavefront to eliminate the dependence on a long guide rail and extend
the measuring range. To eliminate the influence of the test
environment and calculate the R, a defocus transform algorithm is
proposed to instantaneously measure the defocus wavefront from a
single interferogram. Numerical simulations theoretically demonstrate
that there is no limit to the measurement range of this method because
only a short distance of the measured mirror must be moved. A
spherical mirror with a radius of curvature of 101.6087 mm is
experimentally tested, and the relative measurement error is 0.037%.
This method can achieve high accuracy for optical shops and greatly
increase the measurement range of the interferometric method without
additional equipment.

Published: June 2023

Background
Scorpion stings in Brazil represent a major public health problem due to their incidence and their potential ability to lead to severe and often fatal clinical outcomes. A better understanding of scorpionism determinants is essential for a precise comprehension of accident dynamics and to guide public policy. Our study is the first to model the spatio-temporal variability of scorpionism across municipalities in São Paulo (SP) and to investigate its relationship with demographic, socioeconomic, environmental, and climatic variables.

Methodology
This ecological study analyzed secondary data on scorpion envenomation in SP from 2008 to 2021, using the Integrated Nested Laplace Approximation (INLA) to perform Bayesian inference for detection of areas and periods with the most suitable conditions for scorpionism.

Principal findings
From the spring of 2008 to 2021, the relative risk (RR) increased eight times in SP, from 0.47 (95%CI 0.43–0.51) to 3.57 (95%CI 3.36–3.78), although there has been an apparent stabilization since 2019. The western, northern, and northwestern parts of SP showed higher risks; overall, there was a 13% decrease in scorpionism during winters. Among the covariates considered, an increase of one standard deviation in the Gini index, which captures income inequality, was associated with a 11% increase in scorpion envenomation. Maximum temperatures were also associated with scorpionism, with risks doubling for temperatures above 36°C. Relative humidity displayed a nonlinear association, with a 50% increase in risk for 30–32% humidity and reached a minimum of 0.63 RR for 75–76% humidity.

Conclusions
Higher temperatures, lower humidity, and social inequalities were associated with a higher risk of scorpionism in SP municipalities. By capturing local and temporal relationships across space and time, authorities can design more effective strategies that adhere to local and temporal considerations.

Published: June 2023

Pantai Pedelegan merupakan salah satu pantai kawasan wisata yang terletak di Kabupaten Pamekasan. Perairan Padelegan dekat dengan ekosistem mangrove, estuari dan berdekatan dengan tambak garam. Ekosistem tersebut merupakan penunjang kesuburan perairan yang dapat diketahui dari kadar nutrient dan distribusi klorofil-a yang ada. Penelitian ini bertujuan untuk mengetahui distribusi nutrien dan biomassa fitoplankton serta hubungannya dengan parameter kualitas perairan. Pengambilan sampel dilakukan pada sembilan titik. Metode yang digunakan menganalisis kandungan nitrat yaitu bursin asam sulfanilat, fosfat dengan spektrofotometer secara asam askorbat, silika menggunakan metode nessler dan biomassa fitoplankton menggunakan metode APHA. Hasil penelitian menunjukkan bahwa kadar nutrien di perairan Padelegan memiliki distribusi yang berbeda-beda. Kadar nitrat, fosfat dan klorofil-a tertinggi terletak pada titik empat yang merupakan daerah peralihan menuju laut lepas pada arah barat daya. Sedangkan kadar silika tertinggi ditunjukkan pada titik dua yang merupakan daerah pesisir pada arah barat laut. Berdasarkan hasil korelasi rank spearman, silika menunjukkan korelasi yang paling kuat terhadap klorofil-a dibandingkan dengan nutrien lainnya dengan nilai rho(ρ) sebesar 0,5435. Selanjutnya ditambahkan, suhu adalah parameter kualitas air yang memiliki keeratan paling kuat dengan klorofil-a (rho(ρ) = 0,3766). Peningkatan kadar klorofil-a di perairan padelegan berkaitan erat dengan peningkatan kadar nutrien. Pedelegan Beach is one of the beaches in the tourist area located in Pamekasan Regency. Padelegan waters are close to mangrove ecosystems and estuaries and adjacent to salt ponds. This study aims to determine the distribution of nutrients and phytoplankton biomass and their relationship to water quality parameters. Sampling was carried out at nine points using the SNI 6989.59:2008 method. The method used to analyze the nitrate content is brucine sulfanilic acid, phosphate with an ascorbic acid spectrophotometer, silica using the Nessler method, and phytoplankton biomass using the APHA method. The results showed that nutrient levels in Padelegan waters had different distributions. The highest levels of nitrate, phosphate, and chlorophyll-a are located at point four which is a transitional area to the high seas in the southwest direction. While the highest silica content is shown at the second point , a coastal area in the northwest direction. Based on the Spearman rank correlation results silica showed the strongest correlation to chlorophyll-a compared to other nutrients with a rho(ρ) value of 0.5435. Furthermore, the temperature is a water quality parameter that has the strongest affinity with chlorophyll-a (rho(ρ) = 0.3766). The increase in chlorophyll-a levels in Padelegan waters is closely related to the increase in nutrient levels.
UAV patrol path planning based on machine vision and multi-sensor fusion
Authors: Chen Xu 
Published: June 2023

Abstract
With the rapid development of unmanned aerial vehicle (UAV) technology, there are more and more fields of UAV application. This research mainly discusses the UAV patrol path planning based on machine vision and multi-sensor fusion. This article studies how to apply ultrasonic, a classic ranging sensor, to obstacle avoidance of UAVs. The designed ultrasonic obstacle avoidance system is a complete set of hardware and software systems. The hardware part consists of a forward ultrasonic module and a central signal processing module. Among them, a single-axis stabilization gimbal is designed for the forward ultrasonic module, which decouples the attitude angle of the UAV and the pitch detection angle of the ultrasonic sensor. In the central signal processing module, Kalman filtering is performed on the ultrasonic data in the four directions of front, rear, left, right, and left, and the obstacle avoidance control signal is sent to the flight controller according to the filtered sensor data. At the same time, a human–computer interaction interface is also designed to set various parameters of the obstacle avoidance system. For the route planning method of the tower, the routine steps are used to inspect the tower with a single-circuit line, and the specific targets are the insulator string, the ground wire, and the conductor. In this study, the average statistical result of the straight-line distance of the UAV patrolling 100 m is 99.80 m, and the error is only 0.2%. The fusion obstacle avoidance control method based on machine vision is suitable for the engineering application of UAV perception obstacle avoidance. The obstacle avoidance method adopted in this article can be extended to most flight control platforms, and it is a control method with broad application prospects.
Development of renewable energy-based power system for the irrigation support: case studies
Authors: Buts Kumaril , Dewan Lillie , Prasad M. P. R. 
Published: June 2023

Abstract
The development of renewable energy-based applications is nowadays a forced demand of society, for chasing the target set by the governments and the concerned organizations, to reduce or limit the carbon penetration in the environment. Sincere efforts are being made by academics and researchers to create applications based on renewable energy that are reliable and efficient. Green revolutions increase agricultural fields and alter grain production rates, but they also increase energy consumption since agricultural machinery is used more efficiently, mostly for irrigation needs. The purpose of this work is to introduce a hybrid renewable energy system (HRES) that can take the place of the diesel pump often used for time-bound crop irrigation. This HRES system consists of a photovoltaic generator as the main power source supported by a battery energy storage system. For this hybrid system, the development of a Proportional & Integral (PI)-based integrated hybrid controller is proposed to regulate the charge/discharge cycle of the battery energy with maintaining the load demand simultaneously. Controlling of this hybrid system is carried out in the LabVIEW environment.
Subharmonic solutions for a class of predator-prey models with degenerate weights in periodic environments
Authors: López-Gómez Julián , Muñoz-Hernández Eduardo , Zanolin Fabio 
Published: June 2023

Abstract
This article deals with the existence, multiplicity, minimal complexity, and global structure of the subharmonic solutions to a class of planar Hamiltonian systems with periodic coefficients, being the classical predator-prey model of V. Volterra its most paradigmatic example. By means of a topological approach based on techniques from global bifurcation theory, the first part of the paper ascertains their nature, multiplicity and minimal complexity, as well as their global minimal structure, in terms of the configuration of the function coefficients in the setting of the model. The second part of the paper introduces a dynamical system approach based on the theory of topological horseshoes that permits to detect, besides subharmonic solutions, “chaotic-type” solutions. As a byproduct of our analysis, the simplest predator-prey prototype models in periodic environments can provoke chaotic dynamics. This cannot occur in cooperative and quasi-cooperative dynamics, as a consequence of the ordering imposed by the maximum principle.
Electrically driven nanogap antennas and quantum tunneling regime
Authors: Deeb Claire , Toudert Johann , Pelouard Jean-Luc 
Published: June 2023

Abstract
The optical and electrical characteristics of electrically-driven nanogap antennas are extremely sensitive to the nanogap region where the fields are tightly confined and electrons and photons can interplay. Upon injecting electrons in the nanogap, a conductance channel opens between the metal surfaces modifying the plasmon charge distribution and therefore inducing an electrical tuning of the gap plasmon resonance. Electron tunneling across the nanogap can be harnessed to induce broadband photon emission with boosted quantum efficiency. Under certain conditions, the energy of the emitted photons exceeds the energy of electrons, and this overbias light emission is due to spontaneous emission of the hot electron distribution in the electrode. We conclude with the potential of electrically controlled nanogap antennas for faster on-chip communication.
Llibre de paraules e dits de savis e filòsofs: A paremiological portrait of the Catalan-Aragonese Jewry under James II (r. 1291‒1327)
Authors: Navarro David 
Published: June 2023

AbstractLlibre de paraules e dits de savis e filòsofs, by Barcelona-born Jewish translator and physician Jafudà Bonsenyor, is one of the most representative European thirteenth-century proverbial compilations from the Greco-Eastern tradition. The text, written in Catalan at the request of King James II, coincides with a period of socioeconomic upheavals endured by the Jewish communities of that time. This article seeks to examine Jafudà’s book from a perspective other than as it was originally conceived, i.e., as a manual of human conduct. I argue that embedded in the work is an implicit message beyond the parameters of the text itself. The thematic division and the aphorisms selection in theLlibreconvey a subtext that mirrors economic constraints, the decline of Jewish courtiers, religious coercion, and communal frictions borne by the Jewish communities of Catalonia-Aragon. The confluence of these factors acted to redefine the relationship between the Crown and the Jews throughout the rest of the century.
