Royal Road to Coupling Classical and Quantum Dynamics

We present a consistent framework of coupled classical and quantum dynamics. Our result allows us to overcome severe limitations of previous phenomenological approaches, like evolutions that do not preserve the positivity of quantum states or that allow to activate quantum nonlocality for superluminal signaling. A ‘hybrid’ quantum-classical density is introduced and its evolution equation derived. The implications and applications of our result are numerous: it incorporates the back-reaction of quantum on classical variables, it resolves fundamental problems encountered in standard mean field theories, and remarkably, also the quantum measurement process, i.e. the most controversial example of quantum-classical interaction is consistently described within our approach, leading to a theory of dynamical collapse.
The Cultural Integration of Working Vietnamese People in Poland: An Analysis of Integration as the Process of Immigrants’ Lived Experience

This article is devoted to investigating the cultural integration of working Vietnamese immigrants in Poland. This study approaches cultural integration as a process of lived experience, paying particular attention to immigrants’ agency. The migrant group is viewed as active actors who are able to develop motivations for integration into their host culture or reinforce their loyalty to their original culture through interactions with new living settings in their country of residence. This study also examined the role of transnationalism in the process of cultural integration. Qualitative analyses showed that the motivations for cultural integration are strongly shaped by the immigrants’ impression of proper cultural standards and their admiration of the performance of social institutions, modernization, and living conditions in Poland. Motivations for integration played a crucial role in fostering the migrant group’s cultural acquisition. Concurrently, the migrant group exposed their disinclination to internalize cultural standards that challenged their established worldviews formed by socialization and education in the home country. This reluctance happens due to the role of transnational ties by which the migrant group can carry and practice their original culture. Consequently, transnationalism results in cultural resistance, hindering the cultural integration of the migrant group in Poland.
Awareness about new guidelines of national tuberculosis elimination program among medical college faculty

Background: Physicians and faculty working in Medical Colleges play a major role in tuberculosis (TB) control. Their knowledge, attitude, and practices can affect the treatment and care of TB patients significantly. Objectives: The objectives were to assess the awareness about new guidelines of National TB Elimination Program (NTEP) among medical college faculty. Methods: A cross-sectional study was carried out among 95 faculties. They were given anonymous self-administered questionnaire with 23 questions. One mark was given for each correct answer. We classified correct knowledge as score >10 and poor knowledge as score <10. Yates-corrected Chi-square was used to study the association between variables and outcomes. P 0.05 was considered as statistically significant. Results: Questions about case detection rate, cure rate, incentives to private practitioner, bedaquiline, and follow-up of patients after completion of treatment were very poorly answered (<10 persons had correct knowledge). Only 17 could answer about the fixed-dose combinations, 10 about 99 Directly Observed Treatment Short-Course (DOTS) chemotherapy, and 13 about the choice of treatment in HIV-TB. Best answered questions were about the drugs used in each DOTS category, categories of DOTS, what are multidrug-resistant TB, extensive drug-resistant TB, and definition of presumptive case of TB. Overall, 58 faculties (61.1%) had poor knowledge with a score <11. The remaining 37 (38.9%) had correct knowledge with a score 11 or more. Correct knowledge was not found to be associated with age, sex, and designation but was associated with professional experience, with higher experience being associated with poor knowledge (P < 0.05). Conclusion: Majority of the faculty in the studied medical colleges had poor knowledge about new updates/guidelines in the NTEP. Professional experience was found to be significantly associated with the correct knowledge on recent updates in NTEP.
Red cell alloimmunization among antenatal women attending tertiary care center in Jamnagar, Gujarat, India

Background: The following study was conducted to measure the presence of alloantibodies of Rh and other blood group antigens produced due to fetomaternal hemorrhage in all antenatal women as well as those leading to hemolytic disease of fetus and newborn; presenting to a tertiary care center, G.G. Government Hospital, Jamnagar, Gujarat, India, between April 2014 and March 2016 (2 years). Materials and Methods: All multiparous women irrespective of their period of gestation or obstetrics history were included whereas those having taken anti-D immunoprophylaxis or with a history of blood transfusion were excluded. Antibody screening and identification were done using Bio-Rad ID microtyping system. Results: Out of total 8920 multigravida females, 8488 were D-antigen positive whereas 432 were D-antigen negative. A total of 126 antibodies among 117 females (1.31%) were found; out of them, 33 were found in D-antigen positive females (0.39%) and 84 in D-antigen negative ones (19.44%) looking at overall frequency of other antibodies such as anti-C: 9, anti-c: 9, anti-E: 13, anti-Cw: 1, anti-M: 5, anti-S: 8, anti-Fya: 3, and anti-D: 78; it was found that anti-D is the most common. Conclusion: The rate of alloimmunization in D-antigen negative women was found to be very high as compared to other studies in western region; hence, strict follow-up of immunoprophylaxis of all Rh D-negative women needs to be taken care of. Apart from this, D-antigen-positive women also show alloimmunization against various antigens giving the prevalence of 0.39%; hence, it should be mandatory that there should be one standard universal protocol for screening of all antenatal women.
Advances in refractive corneal lenticule extraction

Refractive errors are the leading cause of reversible visual impairment worldwide. In addition to the desired spectacle independence, refractive procedures can improve quality of life, working ability, and daily working performance. Refractive corneal lenticule extraction (RCLE) is a relatively new technique, dependent only on a femtosecond laser (FS). This leads to potential benefits over laser-assisted in situ keratomileusis (LASIK) including a quicker recovery of dry eye disease, a larger functional optical zone, and no flap-related complications. SMILE, available with the VisuMax FS (Carl Zeiss Meditec AG, Jena, Germany), is the most established RCLE application, offering visual and refractive outcomes comparable to LASIK. SmartSight (SCHWIND eye-tech-solutions GmbH, Kleinostheim, Germany) and CLEAR (Ziemer Ophthalmic Systems AG, Port, Switzerland) are two new RCLE applications that received Conformité Européenne (CE) approval in 2020. In this article, we review refractive and visual outcomes, advantages, and disadvantages of RCLE and also report on the latest advances in RCLE systems.
Evaluation of efficacy of Valsalva for attenuating needle puncture pain in first time nonremunerated voluntary plateletpheresis donors: A prospective, randomized controlled trial

Background: Plateletpheresis is generally safe but may have adverse reactions. Adverse reactions can negatively influence donor recruitment and retention. Valsalva is a proven method of attenuating pain caused by venipuncture. Aims: The aim was to evaluate the efficacy of the Valsalva maneuver on the attenuation of needle pain and donor anxiety. Settings and Design: This prospective randomized controlled trial was conducted between November 2015 and April 2016 at the Department of Transfusion Medicine. Subjects and Methods: One-hundred and sixty consecutive donors were grouped into control group (C) and Valsalva group (V) each of sample size 80. The Valsalva group performed a Valsalva maneuver and control did nothing before the venipuncture. Anxiety and pain were scored using a 10 cm visual analog scale (VAS). Severity was graded as VAS = 0 defines no pain and anxiety, VAS = 1–3 as mild pain and anxiety, VAS = 4–6 as moderate pain and anxiety, VAS = 7–9 as severe pain and anxiety, whereas VAS = 10 denotes extreme pain and anxiety. Statistical Analysis: Statistical Package for Social Sciences, version 23 was used for analysis. Independent samples t-test/Mann–Whitney U-test was used to compare between treatment and control group, whereas the Wilcoxon signed-rank test was used to test the difference between pre- and postobservations. Results: In the Valsalva group, post-Valsalva anxiety levels were significantly reduced to (1 [0–2]) from their pre-Valsalva values of (2 [0–3]); (P < 0.001). Pain was significantly lower (2[1-2]) in Valsalva group compared to control (4[2–5]); (P < 0.001). Conclusions: Valsalva reduced both severity of venipuncture pain and anxiety. Valsalva can be performed by donors as it is an easy, painless, and nonpharmacological method of pain and anxiety attenuation.
Prevalence of severe acute respiratory syndrome Coronavirus-2 among the young people and association between diabetes, hypertension, and severe acute respiratory syndrome Coronavirus-2

Background: The corona virus disease-2019 (COVID-19) or corona pandemic is an outgoing pandemic caused by coronavirus 2019 (COVID-19) caused by the transmission of severe acute respiratory syndrome coronavirus-2. It was first identified in Wuhan, China, and the first COVID-19 case in Bangladesh was on March 7, 2020. A retrospective research was conducted on Brahmanbaria Medical College with COVID-19-suspected patients to understand the current situation of COVID-19 in Brahmanbaria. Methods: A total 752 oropharyngeal and nasopharyngeal swab samples were collected from COVID-19 suspected patients and reverse transcriptase–polymerase chain reaction test was run to identify the positive cases. Results: We found 28.5% (n = 214) of positive cases among which 22.9% (n = 49) were diabetes mellitus patients and 20.5% (n = 46) were hypertension patients too. Conclusion: A total of 214 (28.5%) COVID-19 positive confirmed cases among 752 COVID-19-suspected peoples were found. The most common age group of COVID-19 patients was between 31 and 40 years, which is a matter of great concern as these patients develop different postcorona syndromes such as weakness, breathlessness, and muscles pains and cannot go back to their normal daily life as before.

Red cell antibodies resulting in false-positive complement-dependent cytotoxicity cross-match: A unique case

A false-positive complement-dependent cytotoxicity cross-match (CDC XM) has a negative impact in donor selection process obliterating healthy, donor compatible population. A 47-year-old male with chronic kidney disease was planned for ABO-compatible renal transplantation from his sister. CDC and donor-specific antibody (DSA) lysate XM were negative 10 days before transplant. The pretransplant CDC XM showed 40% positivity. DSA lysate XM and HLA antibody screen were negative. Patient's Indirect antiglobulin test (IAT) was positive and anti-M antibody (IgG + IgM) was identified. Therapeutic plasma exchange, intravenous immunoglobulin, and rituximab were used for desensitization. Decrease in positivity of CDC XM and anti-M titer was seen. The transplant was performed successfully. Red cell alloantibody should be considered in differential diagnosis of a positive CDC XM. The utility of DSA lysate XM as a pretransplant monitoring tool is immense in such situations. Institutional policies regarding plan of action in the event of positive CDC XM and negative DSA lysate XM and vice versa should be formed.
Suicide among Indian doctors

Background: India has one of the largest numbers of doctors in the world. It is estimated that more than 1 million doctors are in India. Every year more than 80,000 medical students graduate as doctors from 529 medical colleges in India. Medical profession is considered as more stressful, but mental health is still a subject of taboo in medical profession in Indian context. Doctors have higher suicide risk, 2.5 times more than the general population. In the United Kingdom, 430 doctors committed suicide between the years 2011 and 2015. Even though suicide among doctors is reported in Indian media, there is hardly any scientific study that has looked into the suicide among Indian doctors because of many hurdles in the collection of information. Materials and Methods: All the Indian newspaper that are published in English and are available in the online platform were scrutinized on doctors suicide report from the year 2016 March to 2019 March. Results: Thirty suicides were reported between 2016 March and 2019 March, out of which 18 were female and 12 male. More than 80% were younger than 40 years. Twenty-two were from medical education institutions. Seventeen were from south India and 13 from North India. Eight were MBBS students and ten were postgraduate students. Among subspecialties, six doctors were from Anesthesia. Seventeen used hanging as a method for suicide, eight used medications, and five jumped from building to end life. Nineteen of suicide reports about doctors mentioned that they were depressed. Conclusion: Suicide among Indian doctors is concern. Majority are young undergraduate and postgraduate medical students. Female doctors were more than male doctors. Most doctors were reported to be depressed and used lethal method such as hanging and medications.
SURFACE TREATMENT OF POLYMERS BY PLASMA AND UV RADIATION

This paper aims an analysis on the role of the particle bombardment and UVplasma component in the surface modification of selected polymers. The treated polymer surfaces are shown to perform differently, as a function of their chemical structure, type of exposure, i.e. plasma or UV radiation, and exposure time. Surface analysis results point out to the primary contribution of heavy particles in the modification of the surface outermost layer, since the change induced only by the UV plasma component is considerably lower than that induced by total plasma exposure, although the exposure duration is selected much higher for the UV component. It follows that processes at the very surface of a sample are dominated by reactions involving ions and metastables, while the radiative energy transfer dominates processes in the bulk of the material.
Evaluating High Performing Female Colleagues : The Roles of Race , Gender , and Task Performance

Understanding how high-performing female colleagues are evaluated has significant implications for improving group cohesion and productivity in the workplace. While a great deal of research has been done on identifying high performers and supporting them, little focus has been lent to studying these phenomena in conjunction with the unique issues faced by women and people of color in the workplace. Across two studies, the impact of a participant’s demographics, partner’s race, and performance on a task are measured in regards to their evaluation of a high performing female teammate. Results of this study show that female participants rated their partners higher than male participants did, black participants gave higher ratings when they had a white partner, and men gave higher ratings to their partner when they solved both tasks, whereas women gave higher ratings to their partner when they did not solve either task. These results provide valuable insight into the factors that affect how female high performers are perceived, and add to the growing literature around supporting high performers with marginalized identities.
Biodiesel production from Cannabis sativa oil from Pakistan

ABSTRACT The present study was appraised using response surface methodology for process optimization owing to strong interaction of reaction variables: NaOCH3 catalyst concentration (0.25–1.50%), methanol/oil molar ratio (3:1–9:1), reaction time (30–90 min), and reaction temperature (45–65°C). The quadratic polynomial equation was determined using response surface methodology for predicting optimum methyl esters yield from Cannabis sativa oil. The analysis of variance results indicated that molar ratio and reaction temperature were the key factors that appreciably influence the yield of Cannabis sativa oil methyl esters. The significant (p < 0.0001) variable interaction between molar ratio × catalyst concentration and reaction time × molar ratio was observed, which mostly affect the Cannabis sativa oil methyl esters yield. The optimum Cannabis sativa oil methyl esters yield, i.e., 86.01% was gained at 53°C reaction temperature, 7.5:1 methanol/oil molar ratio, 65 min reaction time, and 0.80% catalyst concentration. The results depicted a linear relationship between observed and predicted values. The residual analysis predicted the appropriateness of the central composite design. The Cannabis sativa oil methyl esters, analyzed by gas chromatography, elucidated six fatty acid methyl esters (linoleic, α-linolenic, oleic, palmitic, stearic, and γ-linolenic acids). In addition, the fuel properties, such as kinematic viscosity at 40°C; cetane number; acid value; flash point; cloud, pour, and cold filter plugging points; ash content; density; and sulphur content, of Cannabis sativa oil methyl esters were evaluated and discussed with reference to ASTM D 6751 and EU 14214 biodiesel specifications.
A NONCOMMUTATIVE TRANSPORT METRIC AND SYMMETRIC QUANTUM MARKOV SEMIGROUPS AS GRADIENT FLOWS OF THE ENTROPY

We study quantum Dirichlet forms and the associated symmetric quantum Markov semigroups on noncommutative L spaces. It is known from the work of Cipriani and Sauvageot that these semigroups induce a first order differential calculus, and we use this differential calculus to define a noncommutative transport metric on the set of density matrices. This construction generalizes both the L-Wasserstein distance on a large class of metric spaces as well as the discrete transport distance introduced by Maas, Mielke, and Chow–Huang–Li–Zhou. Assuming a Bakry–Émery-type gradient estimate, we show that the quantumMarkov semigroup can be viewed as a metric gradient flow of the entropy with respect to this transport metric. Under the same assumption we also establish that the set of density matrices with finite entropy endowed with the noncommutative transport metric is a geodesic space and that the entropy is semi-convex along these geodesics.
Weed segmentation in sugarcane crops using Mask R-CNN through aerial images

In this paper we describe an approach to detect weed regions in sugarcane crops using Mask Regions with Convolutional Neural Networks (Mask R-CNN) on aerial images. Experiments were held with twelve combinations using ResNet-50 and ResNet-101 as backbones. We used both "trained from scratch" and transfer-learning from pre-trained datasets combined with image augmentation techniques for training. The ResNet-101 model with pre-trained COCO achieved an Average Precision (AP50) of 65.5% and obtained values of 0.803, 0.707 and 0.752 for Precision, Recall and F1 score. These results suggest a potential use of Mask R-CNN for weed mapping using aerial images.
Effects of Interfacial Tension, Emulsification, and Surfactant Concentration on Oil Recovery in Surfactant Flooding Process for High Temperature and High Salinity Reservoirs

Surfactant flooding as a potential enhanced oil recovery technology in depleted reservoirs after water flooding has attracted extensive attention. In this study, 12 surfactants belonging to five different types of surfactants and their compounded formulations were investigated for surfactant flooding under 90–120 °C and 20 × 104 mg/L salinity. Two surfactant formulations obtained a stable ultralow interfacial tension (IFT) level (≤10–3 mN/m) with crude oil after aging for 125 days. The surfactant formulations were used to further investigate the effects of the initial IFT values, the dynamic reduction rate of IFT, and the surfactant concentration and emulsification on oil recovery through core flooding experiments. The results indicated that oil recovery increased with the decrease of the initial IFT values and the increase of the dynamic reduction rate of IFT. The 10–3 mN/m IFT level yielded an additional oil recovery of approximately 7% compared with the 10–1 mN/m IFT level. However, under the same IFT .
A Novel Biphasic Neuron Encoder Implementation

In an effort to address the issue of low power and area constraints which are important pre-requisites to many applications in the field of signal processing, this work focuses on the implementation of a novel biphasic neuron architecture, that is proven to be energy efficient, and highly compact. The low power Adaptive exponential integrate and fire neuron (ADEx I&F), is implemented as a biphasic encoder in 180 nm CMOS Technology, and a SER of upto 60 dB and a figure of merit (FOM) of 0.26 pJ/conversion is achieved. The proposed biphasic encoder is found to exhibit similar performance characteristics with respect to the existing architectures while comprising of 52 % lesser number of transistors than the conventional biphasic neuron encoder models.
