Published: February 2023

AbstractRecent advances in machine learning have highlighted the importance of using group equivariant non-expansive operators for building neural networks in a more transparent and interpretable way. An operator is called equivariant with respect to a group if the action of the group commutes with the operator. Group equivariant non-expansive operators can be seen as multi-level components that can be joined and connected in order to form neural networks by applying the operations of chaining, convex combination and direct product. In this paper we prove that each linearG-equivariant non-expansive operator (GENEO) can be produced by a weighted summation associated with a suitable permutant measure, provided that the groupGtransitively acts on a finite signal domain. This result is based on the Birkhoff–von Neumann decomposition of doubly stochastic matrices and some well known facts in group theory. Our theorem makes available a new method to build all linear GENEOs with respect to a transitively acting group in the finite setting. This work is part of the research devoted to develop a good mathematical theory of GENEOs, seen as relevant components in machine learning.
Family language policy in retrospect: Narratives of success and failure in an Indian–Iranian transnational family
Authors: Mirvahedi Seyed Hadi , Hosseini Mona 
Published: February 2023

AbstractIn this study, we investigate family language policy in a transnational family through a collaborative autoethnography. Following the theoretical underpinnings of family language policy (Spolsky in J Multiling Multicult Dev 31:3–11, 2012), we present parental language beliefs, management, and practices in retrospect to shine a light on the long-term impact of the family’s language policy on their daughter’s linguistic development in heritage languages (i.e., Persian and Hindi) and English. The components of the family language policy in this cross-cultural transnational family are sketched in the second author’s narratives of her experiences of multilingual childrearing and heritage language maintenance. We engage with, and critique, recent family language scholarship that apply postmodernist lens to examine families’ translingual use of languages at home to get by their daily life, showing how having failed to set boundaries between the home/heritage languages and English over the past nine years has resulted in their child’s predominant proficiency in English. We argue that such failure has its roots in parents’ own past lived, and future imagined, experiences, as well as language ideologies that are polycentric and scaled, the consequences of which concern emotional, linguistic, cultural and social frictions across generations. Drawing on the narratives of success and failure in the family, we call for critical adoption of translingual frameworks in examining family language policy paying careful attention to the long-term impact of such practices at home on children’s linguistic development.
Effect of rewetting degraded peatlands on carbon fluxes: a meta-analysis
Authors: Darusman Taryono , Murdiyarso Daniel , Impron  , Anas Iswandi 
Published: February 2023

AbstractNumerous studies claim that rewetting interventions reduce CO2 and increase CH4 fluxes. To verify the claim, we conducted a systematic review and meta-analysis of the effects of rewetting on CO2 and CH4 fluxes and dissolved organic carbon (DOC). We identified 28 primary articles eligible for meta-analysis, from which we calculated 48 effect sizes for CO2 emissions, 67 effect sizes for CH4 emissions, and 5 effect sizes for DOC. We found that rewetting significantly decreased CO2 fluxes, with temperate zones showing the highest Hedges’ g effect size (−0.798 ± 0.229), followed by tropical (−0.338 ± 0.269) and boreal (−0.209 ± 0.372) zones. Meanwhile, rewetting increased CH4 fluxes, with the highest Hedges’ g effect size shown in temperate zones (1.108 ± 0.144), followed by boreal (0.805 ± 0.183) and tropical (0.096 ± 0.284) zones. In addition, based on yearly monitoring after rewetting, the CH4 emissions effect size increased significantly over the first 4 years (r2 = 0.853). Overall, the rewetting intervention reduced CO2 emissions by −1.43 ± 0.35 Mg CO2–C ha−1 year−1, increased CH4 emissions by 0.033 ± 0.003 Mg CH4–C ha−1 year−1, and had no significant impact on DOC. To improve the precision and reduce the bias of rewetting effect size quantification, it is recommended to conduct more experimental studies with extended monitoring periods using larger sample sizes and apply the before-after control-impact study design, especially in boreal and tropical climate zones.

Published: February 2023

AbstractMoving-object tracking using a pan–tilt camera setup is quite a well-known task in robotics. However, the presented research addresses specific properties of the tracked object and introduces novel features to the pan–tilt camera control strategy. Pan–tilt camera control does not operate in an isolated environment. It is a part of the visual servoing system with specific goals. The system has to fulfill certain purposes, which affect its configuration and functionality. The pan–tilt system aims at keeping the visually tracked object within the middle of the image. At the same time, the overall visual servoing efficiently recognizes and tracks the object enabling its grasping by the robot arm. It uses a predictive strategy utilizing specific second-order linear models for pan and tilt joints. Model predictive control (MPC) introduces into the system the ability to predict camera operation over the specific horizon according to the predefined tracking goals. As the system anticipates future positions over the horizon of operation, the setpoint prediction of the future tracked system positions is required. Visual object recognition and tracking system use particular strategies for preparing online tracked object extrapolation over MPC horizon. Therefore, the pan–tilt camera system is intrinsically coupled to camera-based recognition and tracking. Predictive pan–tilt positioning keeps the tracked system in the middle of the image, while the visual system extrapolation improves the tracking performance. The proposed approach is thoroughly tested in the dedicated Gazebo-based robot simulator. Finally, the system is implemented and validated on the Velma robot. The results and their comparison with other control strategies confirm the initial assumptions, allowing further visual servoing system development.

Abstract
Background
Acute coronary syndrome (ACS) is a leading cause of mortality and morbidity in Qatar and globally.

Aim
The primary objective of the study was to evaluate the effectiveness of a structured clinical pharmacist-delivered intervention on all-cause hospitalizations and cardiac-related readmissions in patients with ACS.

Method
A prospective quasi-experimental study was conducted at Heart Hospital in Qatar. Discharged ACS patients were allocated to one of three study arms: (1) an intervention group (received a structured clinical pharmacist-delivered medication reconciliation and counselling at discharge, and two follow-up sessions at 4 weeks and 8 weeks post-discharge), (2) a usual care group (received the general usual care at discharge by clinical pharmacists) or, (3) a control group (discharged during weekends or after clinical pharmacists' working hours). Follow-up sessions for the intervention group were designed to re-educate and counsel patients about their medications, remind them about the importance of medication adherence, and answer any questions they may have. At the hospital, patients were allocated into one of the three groups based on intrinsic and natural allocation procedures. Recruitment of patients took place between March 2016 and December 2017. Data were analyzed based on intention-to-treat principles.

Results
Three hundred seventy-three patients were enrolled in the study (intervention = 111, usual care = 120, control = 142). Unadjusted results showed that the odds of 6-month all-cause hospitalizations were significantly higher among the usual care (OR 2.034; 95% CI: 1.103–3.748, p = 0.023) and the control arms (OR 2.704; 95% CI: 1.456–5.022, p = 0.002) when compared to the intervention arm. Similarly, patients in the usual care arm (OR 2.304; 95% CI: 1.122–4.730, p = 0.023) and the control arm (OR 3.678; 95% CI: 1.802–7.506, p ≤ 0.001) had greater likelihood of cardiac-related readmissions at 6 months. After adjustment, these reductions were only significant for cardiac-related readmissions between control and intervention groups (OR 2.428; 95% CI: 1.116–5.282, p = 0.025).

Conclusion
This study demonstrated the impact of a structured intervention by clinical pharmacists on cardiac-related readmissions at 6 months post-discharge in patients post-ACS. The impact of the intervention on all-cause hospitalization was not significant after adjustment for potential confounders. Large cost‐effective studies are required to determine the sustained impact of structured clinical pharmacist-provided interventions in ACS setting.

Published: February 2023

AbstractIn the livestock sector, strategies are available to mitigate gas emissions, such as methane, one of the alternatives that have shown potential correspondence to changes in the composition of the diet. The main aim of this study was to analyze the influence of methane emissions with data on enteric fermentation obtained from the Electronic Data Gathering, Analysis, and Retrieval (EDGAR) database and based on forecasts of methane emissions by enteric fermentation with an autoregressive integrated moving average (ARIMA) model and the application of statistical tests to identify the association between methane emissions from enteric fermentation and the variables of the chemical composition and nutritional value of forage resources in Colombia. The results reported positive correlations between methane emissions and the variables ash content, ethereal extract, neutral detergent fiber (NDF), and acid detergent fiber (ADF) and negative correlations between methane emissions and the variables percentage of unstructured carbohydrates, total digestible nutrients (TDN), digestibility of dry matter, metabolizable energy (MERuminants), net maintenance energy (NEm), net energy gain (NEg), and net lactation energy (NEI). The variables with the most significant influence on the reduction of methane emissions by enteric fermentation are the percentage of unstructured carbohydrates and the percentage of starch. In conclusion, the analysis of variance and the correlations between the chemical composition and the nutritive value of forage resources in Colombia help to understand the influence of diet variables on methane emissions of a particular family and with it in the application of strategies of mitigation.
How European Salafism can make us reflect on a new typology of Salafism?
Authors: Adraoui Mohamed-Ali 
Published: February 2023

AbstractThis article focuses on contemporary Salafism in the European context and how it speaks to the categories Wiktorowicz put forth in his seminal 2006 article. Specifically, it examines how we can identify, describe, and classify the main forms of Salafist religiosity in the context of Western European countries. Furthermore, by examining the relationship to politics, preaching, and orthodoxy and orthopraxy in several European societies, this analysis contributes to the debate on the typologies of Salafism and proposes new ways of conceiving and distinguishing the forms of attachment to this vision of Islam in the context of countries where this religion is a minority. It also shows that the fundamentalist and radical currents are even more attached to it despite or because of the strong attention they receive from the public authorities and the media.
Shadow Coaching Improves Patient Experience for English-Preferring Patients but not for Spanish-Preferring Patients

Published: February 2023

Abstract
Background
Shadow coaching, a type of one-on-one provider counseling by trained peers, is an effective strategy for improving provider behaviors and patient interactions, but its effects on improving patient experience for English- and Spanish-preferring patients is unknown.

Objective
Assess effects of shadow coaching on patient experience for English- and for Spanish-preferring patients.

Design
We analyzed 2012–2019 Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CG-CAHPS) data (n=46,089) from an urban Federally Qualified Health Center with 44 primary care practices and 320 providers. One-third (n=14,631) were Spanish-preferring patients. We fit mixed-effects regression models with random effects for provider (the level of treatment assignment) and fixed effects for time (a linear spline for time with a knot and “jump” at coaching date), patient characteristics, and site indicators, stratified by preferred language.

Participants
The 74 providers who had a 6-month average top-box score on the CAHPS overall provider rating below 90 (on a 100-point scale) were shadow coached. Similar percentages of English-preferring (45%) and Spanish-preferring patients (43%) were seen by coached providers.

Intervention
Trained providers observed patient care by colleagues and provided suggestions for improvement. Verbal feedback was provided immediately after the observation and the participant received a written report summarizing the comments and recommendations from the coaching session.

Main Measures
CG-CAHPS Visit Survey 2.0 provider communication composite and overall provider rating (0–100 scoring).

Key Results
We found a statistically significant 2-point (small) jump in CAHPS provider communication and overall provider rating among English-preferring patients of coached providers. There was no evidence of a coaching effect on patient experience for Spanish-preferring patients.

Conclusions
Coaching improved care experiences for English-preferring patients but may not have improved patient experience for Spanish-preferring patients. Selection and training of providers to communicate effectively with Spanish-preferring patients is needed to extend the benefits of shadow coaching to Spanish-preferring patients.
Omega-3 fatty acids in heart disease—why accurately measured levels matter
Authors: von Schacky C. , Kuipers R. S. , Pijl H. , Muskiet F. A. J. , Grobbee D. E. 
Published: February 2023

AbstractCurrent guidelines barely support marine omega‑3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in cardiology, mainly because results of large trials were equivocal. Most large trials have tested EPA alone or EPA + DHA combined as a drug, thereby disregarding the relevance of their blood levels. These levels are frequently assessed with the Omega‑3 Index (percentage of EPA + DHA in erythrocytes), which is determined using a specific standardised analytical procedure. EPA and DHA are present in every human being at unpredictable levels (even in the absence of intake), and their bioavailability is complex. Both facts need to be incorporated into trial design and should direct clinical use of EPA and DHA. An Omega‑3 Index in the target range of 8–11% is associated with lower total mortality, fewer major adverse cardiac and other cardiovascular events. Moreover, functions of organs such as the brain benefit from an Omega‑3 Index in the target range, while untoward effects, such as bleeding or atrial fibrillation, are minimised. In pertinent intervention trials, several organ functions were improved, with improvements correlating with the Omega‑3 Index. Thus, the Omega‑3 Index is relevant in trial design and clinical medicine, which calls for a widely available standardised analytical procedure and a discussion on possible reimbursement of this test.
Photodegradation of Amido Black 10b Dye Under Visible Light Using Ni and Zn Ferrite Catalysts Prepared by a Simple Modified Sol–Gel Method

Published: February 2023

AbstractThe pure α-Fe2O3, NiFe2O4, and ZnFe2O4 were prepared by a simple modified sol–gel method. The prepared catalysts were characterized by X-ray diffraction, transmission electron microscope, surface area, Zeta potential and optical techniques. The ferrite structure of samples is confirmed. The photocatalytic activity was evaluated toward Amido black 10b dye degradation under visible light at different pHs of 4, 8, and 10 for 90 min irradiation time. The photodegradation toward Amido black b10 dye reached maximum value at pH 8, and it reaches 92%, 89%, and 85% over ZnFe2O4, Fe2O3, and NiFe2O4 photocatalysts; respectively. The increased photoactivity of the ZnFe2O4 sample can also be attributed to its lower bandgap of 2 eV, the formation of the −OH-surface group. Since –OH can interact with the photoexcited holes that were originally formed on the catalyst surface, hydroxyl radicals are produced that have strong oxidizing properties. Whereas; the dye photodegradation is negligible in the case of Fe2O3, and NiFe2O4 catalysts at pH 10, due to the electrostatic repulsion between negatively charged catalyst surface and dye ions at high basic medium. While, in case of ZnFe2O4, the photodegradation reached only 40%.
First principles study of optical properties of Ni- and Pd-doped TiO2 as visible light catalyst

Published: February 2023

AbstractDoping TiO2 with noble metals, transition metals, cations, anions have yielded very promising results in enhancing photocatalytic activity of TiO2 in the visible region and its role in generating alternate forms of energy. Noble metals in general can effectively slow down carrier recombination. However, the study of Pd and Ni as dopant can lead to a reliable and versatile TiO2-modified photocatalyst. In this paper, we explore the optical properties of Pd- and Ni-doped TiO2 by doping with 4.17% Ni and Pd dopant concentrations. The optical properties prove that Ni-doped TiO2 can absorb well in the visible region with an absorption coefficient of 1 × 105 cm−1. Hence, Ni-doped TiO2 can successfully alter the electronic and optical properties of TiO2 for favorable future applications. In the visible region, absorption coefficient of Pd-doped TiO2 supercell is around 1.2 × 105 cm−1 which is comparatively greater than that of pure TiO2 confirming its utility as a versatile and viable visible light photocatalyst. The other optical properties like reflectivity, refractivity, extinction coefficient and electron energy loss spectrum have also been studied.
Multiple targets video tracking based on extended kalman filter in combination with particle swarm optimization for intelligent applications
Authors: Jahantighy Amin , Torabi Hamed , Mohanna Farahnaz 
Published: February 2023

AbstractMultiple targets tracking is a major issue in the intelligent applications. Numerous methods have been presented for the multiple targets tracking to capture the targets trajectory in a video sequence in order to increase intelligence and reduce human error. In this paper, a method is proposed based on combining the Extended Kalman Filter (EKF) and Particle Swarm Optimization (PSO) to construct an intermediate tracker and track targets more accurately. The EKF solves targets collision problem, and PSO reduces the covariance of measured noise. Finally, the Joint Probabilistic Data Association (JPDA) filter is used to reduce the number of multiple hypotheses and create a one-to-one correspondence between targets and measurements. To detect targets, frames subtracting along with background modeling and canny edge detector are used. To reduce running time of the proposed method, number of video frames per second (fps) is reduced from 30 to 10 and the sampling rate is also reduced. Despite of this reduction, simulation reults of the proposed method show the multiple targets tracking with 98% accuracy at an acceptable running time compared to the similar methods. In addition, by using the proposed method, the number of assignment states is reduced in the targets tracking process. Overall, the proposed method not only can be used in the intelligent applications, but also in the video compression applications as well.

AbstractConsider a knot K in $$S^3$$

with uniformly distributed electric charge. Whilst solutions to the Laplace equation in terms of Dirichlet integrals are readily available, it is still of theoretical and physical interest to understand the qualitative behavior of the potential, particularly with respect to critical points and equipotential surfaces. In this paper, we demonstrate how techniques from geometric topology can yield novel insights from the perspective of electrostatics. Specifically, we show that when the knot is sufficiently close to a planar projection, we get a lower bound on the size of the critical set based on the projection’s crossings, improving a 2021 result of the author. We then classify the equipotential surfaces of a charged knot distribution by tracking how the topology of the knot complement restricts the Morse surgeries associated to the critical points of the potential.
