Ballistocardiography reconstruction based on optical fiber sensor using deep learning algorithm

Ballistocardiography (BCG) is the record of body recoils resulted from heart ejection during each cardiac cycle. To detect the detail information in the BCG signal, high sensitivity optical fiber Mach-Zehnder interferometer (MZI) is adopted to fabricate the cushion-type monitor. However, the bias point of the interferometer drifts with the environment affection, which will result in signal fading. In this paper, generative adversarial network (GAN) is proposed to solve the signal distortion problem in the BCG monitoring. The results show that GAN can reconstruct BCG signals with a good performance. © 2021 The Author(s)
Developing a tool to measure interest in audiences of a virtual planetarium show

Informal learning environments often have a clear ambition to spark interest [1]. People also need multiple exposures to content [2, 3] to learn. The Dome+ model, with its principles of interest, identity, and agency, was developed to guide the construction of the Big Astronomy Project consisting of a planetarium show plus additional resources, to support audiences in extending engagement beyond the physical space of the planetarium. A main design principle was sparking interest through the immersive environment of the show. The Big Astronomy Project released a show as a virtual YouTube 360◦ stream due to the COVID-19 pandemic. Here we test the utility of the four-phase interest model [4] to characterize interest surrounding the virtual show for use in our larger dataset. The four-phase model suggests people progress from earlier phases of situational interest induced by the environment to later phases of individual interest marked by self-driven engagement. We use this model to characterize the role the show plays in audience interest and look for the role of interest in a virtual environment. We used focus groups with audience members on our premiere day of the planetarium show consisting of eight individuals, and included follow-up interviews with five of those individuals to understand how they continued their engagement with the Big Astronomy Project. Everyone indicated that they chose to watch the show because of an established interest in astronomy. Since self-induced engagement is an aspect of individual interest, we placed all participants in phases 3 to 4. Our data lacked people who fell into the situational interest phases. We suggest that virtual shows will attract individuals who have an individual interest. We plan to use this research as a tool for the analysis of the larger dataset that includes a more diverse set of individuals. © 2021, American Association of Physics Teachers. All rights reserved.
Specific Risks associated with the Manufacture of Airplanes

Introduction: The aviation industry is growing fast, Boeing and Airbus are the biggest manufacturers in this area. The production and manufacture in the Aviation sector contain specific risks and hazards especially according to the size of the different parts of the airplane. This paper reviews and summarizes some special risks about this production chain, based on the manufacture line of an airbus aircraft. Methodology: The methodology used for this paper is a literature research. Different journal databases and library catalogues have been searched. Qualitative and quantitative studies have been included. Results and Discussion: Production of aircrafts dangles multiple dangers. The specific risks are mostly according to the size of the parts of the airplane, also the scale and level of the different operations are very complex. One big risk factor in the production of an Airbus airplane, is transportation. Airbus produces its parts all over Europe. The transportation to different locations is complicated and executed by different vehicles, ranged from special trucks to Beluga airplanes. To be highlighted here are the wings, which are produced in the United Kingdom and have to been maneuvered through small towns and streets, which are not designed to carry these big transports. This action contains multiple dangers, for the traffic, for the infrastructure and for the people involved in this process. Another specific risk, associated with the manufacture of an airplane is the size of the whole production area. In the size of small towns with big buildings to store and contain all parts of the airplanes, risks and dangers can fast be overlooked. Due to the size of the parts, many operations must be performed at great height. Operators face the risks of falling down the structure or dropping tools onto other people. The fact, that even a small risk that has not been adequately addressed poses a danger to hundreds of people who could later crash in this aircraft, highlights the aircraft industry of others. Conclusions Problems in this area are known, lots of different approaches were made in the past to identify all the risks and dangers, from the detailed approach of checking and analysing every single part, to the approach of including the bigger picture, containing risk scores based on ubiquity and geopolitical risks as well as ERP approaches in the whole manufacturing process.
Concept of sustainable diet

Sustainable nutrition can be characterized as a diet with low environmental impact that is in accordance with good health, which emphasizes at the same time the nutritional adequacy of such a diet to achieve the ge-neral health of the population and its ecological acceptability. The impact of food production and nutrition on the environment occurs in all phases, from food production to household, but also during the deposition of waste generated in the production process or in households, and all of these food-related processes are responsible for emissions of 15-30% of the total GHGs emission. The results of numerous studies have indicated that transi-tion towards more sustainable food consumption requires the replacement of the most animal proteins by plant-derived proteins, because plant-based food have a lower environmental impact as well as a positive effect on health. In recent years, great efforts have been made to implement the concept of sustainability into national food-based dietary guidelines, which primarily requires the awareness and support of national regulatory autho-rities. Finally, it should be noted that the Republic of Serbia is one of the few countries in Europe that hasn’t yet developed national food-based dietary guidelines, moreover it is the leading country in Europe when it comes to the incidence of the chronic non-communicable diseases. In line with the latest global requirements, effort is needed in the future to develop a national dietary guidelines that will have an integrated concept of sustainability.
METHOD OF CALCULATION OF ELASTIC EFFECTIVE PROPERTIES OF TWO-PHASE POLYDISPERSE MEDIA USING MULTIPOINT STATISTICAL DESCRIPTORS AND THE INTEGRAL EQUATIONS TECHNIQUE

Получена: 22 апреля 2019 г. Принята: 20 июня 2019 г. Опубликована: 28 июня 2019 г. Целью данного исследования является разработка новых аналитических подходов для определения эффективных свойств упругих структурно-неоднородных сред на основе многоточечных приближений решений стохастических краевых задач. Предсказание макроскопических свойств неоднородных материалов сопряжено с необходимостью достоверного описания их микроструктурного поведения, включая взаимодействия между отдельными компонентами. К настоящему времени разработан ряд аналитических и численных подходов для оценки эффективных свойств структурно-неоднородных сред, однако ни один из них не дает возможности вычислять эффективные свойства таких сред с абсолютной точностью. Одно из основных ограничений состоит в необходимости в полной мере учитывать особенности микроструктуры среды, такие как ориентация, размер, форма и распределение включений, а также особенности влияния матрицы на включения. В данной работе для расчета эффективных характеристик используются многоточечные приближения решений краевых задач, в которых необходимым является использование моментных функций высших порядков, что в более полной мере позволяет учитывать многочастичное взаимодействие микроструктурных элементов. Получены аналитические выражения для расчета эффективных свойств структурнонеоднородных сред с использованием многоточечных приближения высших порядков решений стохастических краевых задач в упругой постановке. Выполнено численное сравнение результатов расчета относительных эффективных характеристик пористых неоднородных полидисперсных сред со сферическими включениями различной объемной доли. Для численного решения интегродифференциальных уравнений применяется глобальная адаптивная стратегия в совокупности с многомерным правилом интегрирования и правилом преобразования переменных IMT для обращения с сингулярностью функции Грина. Сделаны некоторые заключения об эффективности и ограничениях предложенного подхода.
Developing Decision-Making Algorithm for Unmanned Vessel Navigation Using Markov Processes

: In this study, the autonomous decision-making architecture of unmanned vessel navigation has been formulated. The aim of this study is the advancement of mathematical methods in the ship transportation field with relevance to collision avoidance scenario applications. The process of seafarers safely navigating a vessel at sea entails enacting appropriate decision-making at the appropriate time. In our model, we do not input the appropriate action order based on a seafarer’s experience. The model scores each step’s reward by its action behaviour and learns how to avoid obstacles by itself. By deploying decision timing, state, reward, and digitizing the seafarer’s decision, we establish a reinforcement learning algorithm based on Markov decision processes. In the model training, under a single factor influence, the vessel tends to change course with the best appropriate action behaviour, which is almost consistent with decision-making behaviour based on actual experience at sea.
Post traumatic stress disorder among adults in the aftermath of 2011 Van-Ercis earthquake in Turkey

Objective: The aims of the study were to: (i) screen for PTSD among subjects older than 15 years old living in the Ercis-Van region nine months after the earthquake; and (ii) examine the socio-demographic, clinical and trauma-related factors of PTSD diagnosis. Method: At the time of the earthquakes, the population of Ercis-Van region was 1,050,000. We selected 1498 participants in these areas: 996 from Van and 502 from Ercis, centers using a stratified sampling frame (Kish design). Demographic information, trauma related experiences and past psychiatric history was obtained via sociodemographic survey. The PTSD module of the Composite International Diagnostic Interview (CIDI), along with depression, dysthymia, social anxiety disorder, obsessive compulsive disorder, generalized anxiety disorder structured interview modules were used to directly elicit clinical information. Results: We found that PTSD was prevalent 35.5% among Van earthquake survivors. Analysis of binary Logistic regression showed risk factors, which included some trauma related losses, pre and post traumatic experiences. These risk factors are being female, having depression, loosing any family members or relatives, being unemployed, having serious familial conflicts, severe financial loss, and temporary relocation. Discussion: Our results indicate that in addition to being women, having depression, trauma related losses, like previous traumatic experiences, some pre and post traumatic risk factors are important for development of PTSD. Therefore, after the traumatic event, community based interventions should be structured based on these pre and post disaster risk factors.

Job Satisfaction among Nurses Working Medical Teaching Institutions Khyber Pakhtunkhwa

Job satisfaction is important factor for nurses because nurses are the back bone of hospital. It can be defined by Cambridge English dictionary as ‘the feeling of pleasure and achievement that you experience in your job when you know that your work gives you this feeling’. Job satisfaction is very much related to good productivity and performance. As the responsibility of nurses is increased now a days because the major tertiary care hospital of KPK become Medical Teaching Institution (MTI) means they got autonomy. According to Medical Teaching Institution reforms bill (2015), Medical Teaching Institution means a Medical College, Dental College, or other health related teaching institutions and their affiliated teaching hospitals in the public sector or directly under the control of Government, which provides healthcare services, medical education and training, and medical research. Due to this it is needed to know the job satisfaction of nurses working in Ayub teaching Hospital. A very little work has been done on job satisfaction among nurses but no work is done on Medical Teaching Institution (MTI), previously.
Rapid, Adaptive Human Evolution Facilitated by Admixture in the Americas

Humans have migrated from their ancestral homelands in Africa to nearly every part of the world. Human migration is characterized by a recurrent process of physical isolation and genetic diversification followed by admixture, whereby previously isolated populations come together and exchange genes. Admixture results in the introgression of alleles from ancestral source populations into hybrid admixed populations, and introgression can facilitate rapid, adaptive evolution by introducing beneficial alleles at intermediate frequencies. We provide examples of adaptive introgression between archaic and modern human populations and for admixed populations in the Americas, which were formed relatively recently via admixture among African, European, and Indigenous American ancestral populations. Adaptive introgression has had an outsized effect on the human immune system. In light of the ubiquity of admixture in human evolution, we propose that adaptive introgression is a fundamentally important mechanism for driving rapid, adaptive evolution in human populations.
Interspecific divergence of circadian properties in duckweed plants

The circadian clock system is widely conserved in plants; however, divergence in circadian rhythm properties is poorly understood. We conducted a comparative analysis of the circadian properties of closely related duckweed species. Using a particle bombardment method, a circadian bioluminescent reporter was introduced into duckweed plants. We measured bioluminescence circadian rhythms of eight species of the genus Lemna and seven species of the genus Wolffiella at various temperatures (20, 25, and 30 °C) and light conditions (constant light or constant dark). Wolffiella species inhabit relatively warm areas and lack some tissues/organs found in Lemna species. Lemna species tended to show robust bioluminescence circadian rhythms under all conditions, while Wolffiella species showed lower rhythm stability, especially at higher temperatures. For Lemna, two species (L. valdiviana and L. minuta) forming a clade showed relatively lower circadian stability. For Wolffiella, two species (W. hyalina and W. repanda) forming a clade showed extremely long period lengths. The circadian properties of species primarily reflect their phylogenetic positions. The relationships between geographical and morphological factors and circadian properties are also suggested.
Genotypes Environment Interaction for Seven-Week Body Weight of Poultry Breeds

This study investigated the interaction of poultry breeds x environment under Libyan conditions and compared with that under a temperate zone for a seven-week bodyweight. Data were collected from the weekly records during the rearing period for three grandparent breeds Hypeco, Avian, and Shaver, at Ghotsultan and Tawargha from 1986 to 2001. Traits studied were daily feed consumption, cumulative feed consumption, body weight, feed consumption ratio, and mortality. The model used to analyze the data for the rearing period was included: overall mean, the effects of location, breeds within the year, the flock, seasons, and the age. Breeds x seasons and breeds x locations interaction were found in weight at seven weeks of age. Avian showed consistent performance under both hot and cold seasons for seven weeks bodyweight (1308.3-1304.4g), while Hypeco and Shaver perform well under cold seasons but not in hot seasons in Libya. Hypeco and Avian perform less under Libyan conditions compared to temperate zone conditions, whereas Shaver performs a little better under Libyan conditions. In addition, Hypeco had lower mortality, which was about 2.84%, compared with Avian 3.0%, and Shaver, which was 4.38% during the rearing period. This study could conclude that the performance of grandparent breeds under Libyan conditions was affected by weather and management.
Berberine Phospholipid Is an Effective Insulin Sensitizer and Improves Metabolic and Hormonal Disorders in Women with Polycystic Ovary Syndrome: A One-Group Pretest–Post-Test Explanatory Study

Polycystic Ovary Syndrome (PCOS) is the most frequent endocrine disease in females of reproductive age and is characterized by multifactorial unhealthy conditions related to hormonal unbalance and also to dysmetabolism and inflammation. Recently, increasing evidence has shown that natural plant-based products may play a role in PCOS management. The aim of this one-group pretest–post-test explanatory study was to evaluate, in normal–overweight PCOS women with normal menses, the effectiveness of berberine on: Insulin resistance (IR) by Homeostasis Model Assessment (HOMA); Inflammation by C-Reactive Protein (CRP), Tumor Necrosis Factor α (TNF-α); Lipid metabolism; Sex hormone profile and symptoms correlated to hyperandrogenism, such as acne, by Global Acne Grading System (GAGS) and Cardiff Acne Disability Index (CADI); Body composition by DXA. Finally, adverse effects were assessed by liver and kidney functions and creatine phosphokinase (CPK). All these parameters were collected at baseline and 60 days after supplementation with a new bioavailable and safe berberine formulation. Twelve females (aged 26.6 ± 4.9, BMI 25.3 ± 3.6) were supplied for 60 days with two tablets/day (550 mg/table) of the bioavailable berberine. Results showed a statistically significant decrease in HOMA, CRP, TNF-α, Triglycerides, testosterone, Body Mass Index (BMI), Visceral Adipose Tissue (VAT), fat mass, GAGS and CADI scores, and a statistically significant increase in sex hormone-binding globulin (SHBG). Liver and kidney functions and CPK are not statistically significantly different. Therefore, berberine can represent a safe novel dietary supplement, helpful in treatment strategy for PCOS.
Clostridium difficile in Autologous Hematopoietic Stem Cell Transplant Patients

Diarrhea is a common complication of hematopoietic stem cell transplant (HSCT) due to multiple etiologies, including toxicity from the conditioning regimen and Clostridium difficile (C. difficile) infection. We hypothesized that C. difficile infection is uncommon in recipients of autologous HSCT (auto-HSCT) and testing for C. difficile is over utilized at our institution. We performed a retrospective, single center analysis of the use of polymerase chain reaction (PCR) testing for C. difficile among adult auto-HSCT recipients in the first 45 days post-procedure. Patients were identified by cross referencing the existing list of patients who had an auto-HSCT between May 2011 and May 2014 with the Premier SafetySurveillor® list of C. difficile PCR tests conducted in patients during the same time period. Among the 160 patients identified, the incidence of C. difficile infection was 5.0% with nearly three-quarters of auto-HSCT patients being tested. We further reviewed C. difficile PCR positive patients for risk factors according to Infectious Diseases Society of America (IDSA) guidelines for C. difficile infection. Based upon assessment of risk factors in patients who tested positive for C. difficile infection, we recommend additional study to evaluate for the need for antimicrobial prophylaxis with fluoroquinolones during the neutropenic post-transplant period as well as proton pump inhibitor (PPI) therapy in this patient population. Limiting the use of these agents could be a method to decrease C. difficile risk factors; therefore, potentially decreasing PCR testing and C. difficile infection.
Revealing the Risk Perception of Investors using Machine Learning

Text in corporate disclosures conveys important information to financial market participants. If incorporated in quantitative models, the intended meaning of a text is often hidden by the use of idiosyncratic terminology within an industry-specific vocabulary. This study uses an unsupervised machine learning algorithm, the Structural Topic Model, to overcome this issue. It illustrates the connection between machine-extracted risk factors discussed in corporate disclosures (10-Ks) and the corresponding pricing behavior of investors for a not yet investigated US REIT sample from 2005 to 2019. When disclosed, most risk factors counterintuitively decrease stock return volatility and are therefore beneficial for the pricing process on financial markets.
