On optimization of the mixed charging infrastructure of electric buses for urban routes
Authors: Rozin B. M. , Shaternik I. A. 
Published: June 2022

Objectives. When transition from a fleet of diesel buses to a fleet of electric buses, it is important to optimize the charging infrastructure, which combines the slow-charging technologies at the depot overnight and fast recharging at the terminals of the routes. The purpose of the study is to create models and methods for developing the cost-effective solutions for selecting this type of charging infrastructure for a fleet of electric buses serving the city route system, taking into account a number of specific conditions. The operation of the fleet and charging infrastructure is modeled both for the depot at night and for the terminal stops in the most representative period of the day, characterized by the highest intensity of passenger traffic and maximum power consumption.Methods. Methods of set theory, graph theory and linear approximation are used.Results. A mathematical model has been developed for the problem of optimizing a mixed-type charging infrastructure for an electric bus fleet. The total daily cost of charging stations, degradation of electric bus batteries and consumed electricity was chosen as the objective function. The model is formulated as a mixed integer linear programming problem.Conclusion. To solve the formulated problem, standard solvers like IBM ILOG CPLEX can be used. The solution of the problem lies in the choice of durations and schedules for charging electric buses at low-capacity charging stations in the depot at night and at high-capacity charging stations of terminal stops in a given range of peak hours.

Published: June 2022

Objectives. The problem of reducing the dynamic range of infrared images for their reproduction on display devices with a narrow dynamic range is considered. The method of local image histogram equalization based on the integral distribution function of brightness is investigated. To transform the brightness of a pixel, this method uses an approximation of the local alignment values of the nearest blocks of pixels of original image. This in-creases the local contrast of the image, but leads to high computational complexity, which is increasing while block size decreases. The aim of the work is to reduce the computational complexity of adaptive equalization and compression of infrared image histograms while reducing their dynamic range.Methods. Image processing methods are used.Results. To reduce the computational complexity of transforming the dynamic range of infrared images, a block-priority modification of the adaptive histogram equalization method is proposed. The modification is based on the division of the set of image blocks into two subsets of high-priority and low-priority blocks depend-ing on their brightness statistical properties. When interpolating pixel values, high-priority blocks use local alignment values, and low-priority blocks use global alignment values. As a result, the total number of alignment vectors is reduced in proportion to the ratio of subsets sizes and the computational complexity of the dynamic range transformation is reduced.Conclusion. When changing the ratio of the number of high-priority blocks of infrared image pixels to the number of all blocks in the range of 0.25–0.75, the proposed algorithm is more efficient than global and adaptive histogram equalization algorithms.

The Streaming Instability Cannot Form Planetesimals from Millimeter-size Grains in Pressure Bumps
Authors: Carrera Daniel , Simon Jacob B. 
Published: June 2022

Abstract
We present evidence that it is unlikely that the streaming instability (SI) can form planetesimals from millimeter grains inside axisymmetric pressure bumps. We conducted the largest simulation of the SI so far (7 million CPU hours), consisting of a large slice of the disk with millimeter grains, a solar-like dust-to-gas ratio (Z = 0.01), and the largest pressure bump that does not cause gravitational instability (GI) in the particle layer. We used a high resolution of 1000/H to resolve as many SI unstable modes as possible. The simulation produced a long-lived particle overdensity far exceeding the SI criteria (i.e., a critical solid abundance to headwind parameter ratio Z/Π) where strong clumping would occur if these conditions were present over an extended region of the disk; yet we observed none. The likely reason is that the time it takes particles to cross the high-Z/Π region (t
cross) is shorter than the growth timescale of the SI (t
grow). We propose an added criterion for planetesimal formation by the SI—that t
cross > t
grow. We show that any bump larger than the one in this run would form planetesimals by the GI instead of the SI. Our results significantly restrict the pathways to planet formation: either protoplanetary disks regularly form grains larger than 1 mm, or planetesimals do not form by the SI in axisymmetric pressure bumps. Since bumps large enough to induce the GI are likely Rossby-wave unstable, we propose that millimeter grains may only form planetesimals in vortices.

Abstract
Coalescing binary black hole (BBH) systems are likely formed via several channels, and it is challenging to understand their formation/evolutionary processes. Some features in the mass function of the primary components (m
1), such as the distinct Gaussian-like peak located at ∼34 M
⊙, have been previously found. In this work, we investigate the possible dependence of the mass ratio (q = m
2/m
1) distribution on the primary mass. We find a Bayesian odds ratio of 18.1 in favor of divergence in the mass ratio distributions between the low- and high-mass ranges over an invariable mass ratio distribution. BBHs with m
1 ≳ 29 M
⊙ have a stronger preference of being symmetric compared to those with m
1 ≲ 29 M
⊙ at a 97.6% credible level. Additionally, we find mild evidence that BBHs with m
1 located in the Gaussian-like peak have a mass ratio distribution different from that of other BBHs. Our findings may favor some formation channels, such as chemically homogeneous evolution and dynamical assembly in globular clusters/nuclear star clusters, which are more likely to provide symmetric BBHs in the high-mass range.
Les évolutions du vote catholique
Authors: Fourquet Jérôme , Sarthou-Lajus Nathalie 
Published: June 2022

Le vote des catholiques lors des dernières présidentielles correspond à celui de l’ensemble de la société française, tout aussi diversifié et fragmenté. Il est néanmoins possible d’identifier un « bloc catholique » dont les comportements sont assez marqués et qui adhère de plus en plus à un discours national identitaire porté par la droite et l’extrême droite. Selon le directeur de l’Ifop, la perte d’influence de la matrice catholique en France sur la société et la culture n’est pas pour rien dans cette évolution.

L’écosystème d’affaires comme perspective d’étude de la convergence des acteurs de l’œnotourisme en Val de Loire (France)
Authors: Noblet Jean-Pierre , Poutier Elizabeth 
Published: June 2022

En France, les enjeux liés à l’économie du tourisme vitivinicole sont fondamentaux, autant pour l’accroissement de la fréquentation touristique des régions viticoles, que pour la stimulation de la vente des produits vinicoles. Malgré la richesse œnotouristique de la France, beaucoup d’acteurs proposent une offre encore peu lisible sur le marché national et international. La grande hétérogénéité des facteurs clés de réussite des principaux modèles de développement à l’international (Australie, Espagne, Portugal, Chili, Canada…) ne facilite pas notre réflexion quant à l’existence d’un écosystème d’affaires pertinent et universel. Notre travail de recherche consistera donc à fournir un cadre théorique susceptible de nourrir notre réflexion (l’approche par les écosystèmes d’affaires), et d’envisager des pistes de développement propres à nos régions, et plus spécifiquement à notre terrain d’étude, le Val de Loire (France). Les conclusions restent mitigées : il n’y a pas d’écosystème d’affaires fiable en Val de Loire, car aucun leader n’émerge, et il n’y a pas de vision partagée et de préservation du label sur le long terme.
The surprisingly long history of the Olympics of Antioch (AD 212-520)
Authors: Remijsen Sofie 
Published: June 2022

The Olympics of Antioch were – as far as we know – the last surviving agon of antiquity and definitely the most prominent in Late Antique literature. This paper aims to counter the tendency to discuss them as separate from the imperial-age agones. The first section underlines how the Olympics of Antioch were simply an addition to a preexisting set of Antiochene contests, and how similar they were to other local Olympics. The second section presents some factors that made this ordinary agon stand out. It contains a brief discussion of the positive role that Antioch had as capital of Syria and of the diocese of the Orient on the contest’s Late Antique development. This section’s main focus is the rationale behind and the consequences of the choice of Daphne as its venue. A survey of the sporting accommodation in the city and at Daphne makes clear that, at the time of the games’ foundation, Daphne was not the obvious choice from a logistical point of view. But, as the example of the oldest Olympics could show, the road between the organizing city and the sanctuary of choice was not considered a hurdle. The lengthy procession drew the people in and created an idealized image of the city and its entire community. It created a strong link between the Olympics and the Antiochene identity, which made the festival impervious to the breakdown of the wide agonistic network of contests. The epilogue argues that the ban by Justin I in a particularly riotous period was probably meant to be temporary, but the natural disasters of the 520s made a return of the beloved festival impossible.
A single - center retrospective observational study on patients undergoing Encephalo-Duro-Arterio -Myo-Synangiosis in patients with moyamoya disease
Authors: Hazra Darpanarayan , Chandy Gina Maryann , Ghosh Amit Kumar 
Published: June 2022

BACKGROUND:
Many cases of moyamoya disease are refractory to conventional medical therapy, hence surgical revascularization techniques have emerged as one of the primary choices of treatment. In this study, we present the functional and angiographic outcomes of patients undergoing encephalo-duro-arterio-myo-synangiosis (EDAMS).

METHODS:
This is a retrospective observational cohort study, done over 8 years (2012–2020) in a neurological center in Eastern India. Data were retrieved from the hospital's electronic system, recorded in a standard data abstract sheet, and analyzed.

RESULTS:
This study included 75 patients, with a male (n = 42; 56.0%) preponderance. Majority belonged to the pediatric age group (≤18 years) (n = 70; 93.3%); remaining adult population included 5 (6.6%) patients. The most common presenting complaint was that of an ischemic cerebrovascular accident (CVA) (n = 57; 76.0%). Symptomatic hemispheres (n = 69; 92.0%) were treated and later followed if they had progressed to bilateral disease formation. Preoperative DSA showed 50 (71.4%) to have Suzuki grade 3 type of angiographic findings. Postoperative complications included worsening unilateral hemiparesis 4 (40%), slurring of speech (n = 2; 20.0%), hematoma (n = 2; 20.0%), and surgical site infection (n = 2; 20.0%). One patient succumbed to his illness on the second postoperative day. A postoperative angiogram showed regression of moyamoya vessels in the majority (n = 69; 93.3%) of patients. All (n = 74; 100%) had an intensification of transdural vessels; none had a regression. None of the study participants showed an intensification of moyamoya vessels. Many of our patients (83.8%) had a good grade of revascularization (modified Matsushima and Inaba A and B), while 16.2% had low-grade revascularization (grade C). On assessing outcomes using a modified Rankin Score, a large number of our patients had an excellent (n = 45, 60%) neurological outcomes.

CONCLUSION:
There was a bimodal age distribution with most of them presenting with ischemic CVA. This procedure (EDAMS) had good angiographic (Matsushima and Inaba) and functional (modified Rankin Score) outcomes.

Introduction:
Chronic kidney disease with uncertain etiology (CKDu) was first recognized in the 1990s in Sri Lanka. Considering the distribution of CKDu in the country, clusters of endemic and nonendemic areas can be identified. This study was carried out to compare the biochemical characteristics between CKDu endemic and nonendemic areas in Sri Lanka.

Materials and Methods:
A cross-sectional study was carried out among randomly selected males between the age category of 30 and 60 years in selected villages of Wilgamuwa (endemic) and Hanguranketha (nonendemic), located in the dry and wet zone, respectively.

Results:
The total participation percentage from the endemic area was 74.7% (224 out of 300 invitees). Out of 150 participants invited from the nonendemic area, only 100 participated in the study cohort. There was a striking difference between the two areas in serum creatinine levels (P = 0.001). When considering the behavioral patterns of the two study areas, the main occupation was farming and there was no significant difference between the behaviors of the people in the selected areas. A significant number of participants (n = 31, 13.8%) from the endemic area had high serum creatinine levels with a mean of 109 μmol/L (standard deviation [SD] = 66.41) (normal: 90–116 μmol/L). Whereas, in the nonendemic area, only 3 (3%) participants had elevated creatinine levels with a mean value of 85.41 μmol/L (SD = 18.78). A significant difference was observed in the two groups in the mean values of serum creatinine levels (P = 0.001). The mean value of random blood sugar (RBS) was 113.56 mg/dL (SD = 44.38) and 119.10 mg/dL (SD = 50.48) in endemic and nonendemic areas, respectively. There was no significant difference between the mean values of RBS (P = 0.2). The mean serum cholesterol was slightly higher in Wilgamuwa (119.26 mg/dl, SD = 45.31) compared to Hanguranketha (189.02 mg/dl, SD = 45.09). However, that was not statistically significant (P = 0.6).

Conclusions:
Serum creatinine is remarkably increased in CKDu endemic areas. RBS and serum cholesterol are less significant according to the endemicity of CKDu.
Knowledge, attitudes and utilization of food labels among undergraduate medical students in a medical college in Chennai – A cross sectional survey
Authors: Annamalai Sinthiya , Gopichandran Vijayaprasad 
Published: June 2022

Introduction:
Food labeling is an important method of providing food-related information on the package of food products, to facilitate people's choice of safe and appropriate foods. Medical students are potential agents of change in food label utilization behavior in the community. The objectives of this study were to evaluate the knowledge, attitudes, and utilization of food labels among undergraduate medical students in a medical college in Chennai.

Material & Methods:
We conducted a cross-sectional survey of 200 students studying in the 1st to 3rd year in a medical college through an online Google Forms survey, self-administered by the students after online informed consent was obtained. We gathered information on their knowledge, attitudes, and utilization of food labels.

Results:
Of 400 students approached, 200 responded to the online survey. They had good knowledge about food labels. Female students had 3.4 (1.59 to 7.25) times better knowledge compared to men. The students had a positive attitude toward food labels, and a majority thought that the food labels are useful. Utilization of food labels to understand the nutritive content (55%), additives (57%), and manufacturer details (47%) was poor. Utilization of food labels was 2.7 times more (1.142–6.587) among those who did regular exercise, and it was 0.2 (0.09 to 0.9) times less among those who were on a strict diet.

Conclusion:
Medical students had a sound knowledge and good attitude toward food labels, but their food label utilization patterns were still poor. There is a need to incorporate food labeling in the undergraduate medical curriculum and inculcate better food label utilization behavior.

Published: June 2022

Introduction:
The immunosuppressant regimen after kidney transplantation typically includes initial induction therapy followed by a maintenance regimen. The induction therapy was introduced with the aim of reducing acute rejections. A retrospective study was conducted to compare the outcomes in patients with different modalities of induction.

Materials and Methods:
This is a hospital-based retrospective study where 148 patients who have undergone live renal allograft transplantation at SCB Medical College and Hospital from March 2012 to February 2019 were included in the study. All cases included were crossmatch negative, ABO-compatible live renal allograft transplantations. All patients received tacrolimus, mycophenolate sodium, and steroids. Induction therapy varied depending on immunological risk and changes in protocol over time. Basiliximab, anti-T-lymphocyte globulin (ATLG), and anti-thymocyte globulin (ATG) were given in 56, 21, and 21 patients, respectively, and no induction therapy in 50 patients. All patients with an acute rise in serum creatinine and without an obvious cause of graft dysfunction were subjected to renal biopsy. The incidence of acute rejection, patient survival, and graft survival was calculated from the follow-up records and compared among patients receiving different induction therapies.

Results:
In the high-risk category patients, 31%, 20%, and 18.2% of patients (P = 0.6) and in the low risk category, 37%, 27.3%, and 20% of patients (P = 0.6) had acute rejections in basiliximab, ATLG, and ATG group, respectively. The patient survival at 1 year was 79.3%, 70%, and 81.8% in high-risk group patients (P = 0.84) and 88.9%, 81.8%, and 80% in low-risk group patients (P = 0.88) in the basiliximab, ATLG, and ATG groups, respectively. The graft survival at 2 years was 96.6%, 90%, and 90.9% in high-risk group patients (P = 0.32) and 88.9%, 90.9%, and 90% in low-risk group patients (P = 0.65) in the basiliximab, ATLG, and ATG groups, respectively.

Conclusion:
In the low-risk group, the use of different modalities of induction does not have any advantage over no induction therapy in reducing the incidence of acute rejection, or improving patient and graft survival. In the high-risk group, all the induction therapies used lead to similar outcomes and none show any advantage over the other in terms of statistical significance. However, patients who received ATLG or ATG have an increased incidence of septicemia as compared to basiliximab and no induction group.

ABSTRACT

Context:
Soil-transmitted helminths (STH) infections are among the most common and widespread infections in developing countries where sanitation facilities are inadequate.

Aims:
This study aimed to estimate the prevalence of STH infections in prenatal mothers in two states in India.

Settings and Design:
A cross-sectional survey was conducted in Maharashtra and Rajasthan state of India. We randomly selected one municipal corporation and one rural block from a selected district in each state.

Methods and Material:
Out of 2400 contacted, 2206 pregnant women gave stool samples for microscopy for parasitological study. The response rate was 89.91%. Stool specimens were transported to an accredited lab and examined microscopically within 24 hrs.

Results:
Prevalence of STH was 8.34 (95%CI 7.22–9.57). The prevalence in rural and urban areas was 10.01% (95%CI 8.51–11.74) and 5.76% (95%CI 4.39–7.52), respectively. Ascaris lumbricoides (34.7%) were the most common, followed by Entamoeba histolytica (30.43%), and 20.1% were mixed infections. Higher age, walking barefoot, weight gain during pregnancy were significantly associated with STH (p < 0.05). The mean hemoglobin value in women with STH was significantly less (8.75 gm%; SD 4.04) compared to those without STH (10.23 gm%; SD 1.23) (p < 0.05), and average weight gain during pregnancy was significantly less among women with STH (3.80 kg; 4.11) compared to women without STH (8.45 kg; 2.83); (p = 0.000).

Conclusion:
The study provides valuable insights into the burden and intensity of STH in pregnant women that may support the policy recommendation for deworming during pregnancy.
