Accurate Fall Detection and Localization for Elderly People Based on Neural Network and Energy-Efficient Wireless Sensor Network

Falls are the main source of injury for elderly patients with epilepsy and Parkinson’s disease. Elderly people who carry battery powered health monitoring systems can move unhindered from one place to another according to their activities, thus improving their quality of life. This paper aims to detect when an elderly individual falls and to provide accurate location of the incident while the individual is moving in indoor environments such as in houses, medical health care centers, and hospitals. Fall detection is accurately determined based on a proposed sensor-based fall detection algorithm, whereas the localization of the elderly person is determined based on an artificial neural network (ANN). In addition, the power consumption of the fall detection system (FDS) is minimized based on a data-driven algorithm. Results show that an elderly fall can be detected with accuracy levels of 100% and 92.5% for line-of-sight (LOS) and non-line-of-sight (NLOS) environments, respectively. In addition, elderly indoor localization error is improved with a mean absolute error of 0.0094 and 0.0454 m for LOS and NLOS, respectively, after the application of the ANN optimization technique. Moreover, the battery life of the FDS is improved relative to conventional implementation due to reduced computational effort. The proposed FDS outperforms existing systems in terms of fall detection accuracy, localization errors, and power consumption.
Nepali Medical Students’ Knowledge and Attitude towards LGBT Population

The umbrella term “lesbian, gay, bisexual, and transgender (LGBT)” is widely used to denote sexual and gender minority individuals. But the discrimination still exists in the medical community regarding the sexual identity because the knowledge about those rights is insufficient. Further, the skills and techniques to provide social and psychological support are not scientific in the medical community. The aim of the study was to assess the medical students’ knowledge and attitude towards LGBT population. This cross-sectional study was carried out in 2017 at Kathmandu University with a sample size of 180 undergraduate and medical intern students. Data was collected using a self-administered questionnaire. Data was analyzed using descriptive and inferential statistics (Mann-Whitney test, Kruskal-Wallis test, t-test and ANOVA). Finding shows the mean score of knowledge was 12.32 (±3.7), and attitude was 73.04 (±9.82). The mean coefficient attitude score was 13.44. Being female students and those who were very frank to teacher had a higher knowledge of LGBT. Similarly, internship medical students had a better attitude towards LGBT than other students. This study found higher knowledge and attitude were highly correlated. Being female students had higher knowledge of LGBT and Internship medical students had better attitude towards LGBT population.
Assessment of war effects on the publishing activity and scientific interests of Ukrainian scholars

This paper highlights war effects on publication activities and scientific interests of Ukrainian researchers. Moreover, it presents the moods and motives of Ukrainian scientists regarding their scientific activity and the publication of their results in academic journals. The research method was a survey (Google Forms) distributed through Facebook professional groups “Ukrainian Scientists Worldwide,” “Ukrainian cuisine of scientific publications,” “Scientific Conferences and Publications,” and “Higher School and Science of Ukraine: Disintegration or Blossoming? ” 690 Ukrainian scientists took part in the survey. Only 35.7% of the respondents stated that the war did not affect their research process. Results from respondents demonstrated that 27.7% of the respondents changed their scientific interests because of full-scale Russian aggression. Furthermore, scientists have psychological problems due to the loss of home, relatives, and relocation. The survey showed that motivation for publishing scientific articles varies from informing colleagues of their scientific results, scientific interest to motives distant from scientific values – “fulfillment of the requirements of the institution where I work,” “I do not want to be fired,” etc. 20.0% of the respondents noted that they had not got any motivation for scientific activity and publishing. At the same time, most scientists consider state security, debunking the propaganda of the Russian Federation, economic development, military medicine, ecology, education, social sphere, and agriculture to be the leading research areas. They also see the need to raise public awareness of the role of science and synchronize current multidisciplinary scientific research.
Biogeographic patterns of polyploid species for the angiosperm flora in China

Exploring the frequency and distribution pattern of polyploid species in geographic parameters is of significance in understanding the mechanisms of polyploid speciation and evolutionary drivers of biodiversity. We here explored polyploid and paleopolyploid incidence frequency in a scale of 100 × 100 km grids in China. We found 33% of angiosperm species are polyploidy in China, and 23% of polyploid speciation. Western China and eastern China showed a significantly different polyploid and paleopolyploid frequency, with an evolutionary cradle of polyploid angiosperms in the Qinghai–Tibetan plateau. Herbaceous species exhibited higher polyploid frequency but lower paleopolyploid frequency than woody species, indicating the former experienced more rapid differentiation and speciation than the latter. Our results indicate that western China is an evolutionary cradle for polyploid angiosperms where harsh environment facilitates the establishment and survival of polyploids, while polyploid lineages tend to rediploidize to be diploids with sufficient time in suitable environment.

Perspectives on the Acceptance and Social Implications of Smart Glasses: A Qualitative Focus Group Study in Healthcare

Abstract Smart glasses were perceived to be potentially revolutionary for healthcare, however, there is only limited research on the acceptance and social implications of smart glasses in healthcare. This study aims to get a better insight into the theoretical foundations and the purpose was to identify themes regarding adoption, mediation, and the use of smart glasses from the perspective of healthcare professionals. A qualitative research design with focus groups was used to collect data. Three focus groups with 22 participants were conducted. Data were analyzed using content analysis. Our analysis revealed six overarching themes related to the anticipated adoption of smart glasses: knowledge, innovativeness, use cases, ethical issues, persuasion, and attitude. Nine themes were found related to anticipated mediation and use of smart glasses: attention, emotions, social influences, design, context, camera use, risks, comparisons to known products, and expected reaction and might influence the acceptance of smart glasses.
The Effects of Bacillus licheniformis—Fermented Products on the Microbiota and Clinical Presentation of Cats with Chronic Diarrhea

Simple Summary Probiotics are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit to the host. Probiotics have also been introduced in companion animals in recent years, and the main priority of probiotic use has focused on the health of individual animals. This study aimed to compare the fecal microbiota of cats with chronic diarrhea with that of healthy cats from the same household and evaluate the effectiveness of oral administration of Bacillus licheniformis-fermented products (BLFP) in relieving clinical signs and altering the intestinal microbiota in diarrheal cats. Overall, this study provides basic information on the types and ratios of fecal microbiota in healthy cats and cats with chronic diarrhea. Our results also demonstrated that oral administration of BLFP could significantly impact the relief of clinical gastrointestinal symptoms and the gastrointestinal microbiomes in cats with diarrhea. Abstract Bacillus licheniformis-fermented products (BLFP) are probiotics with antibacterial, antiviral, and anti-inflammatory properties that can improve growth performance. This study aimed to compare the fecal microbiota of diarrheal cats with chronic diarrhea (n = 8) with that of healthy cats (n = 4) from the same household using next-generation sequencing, and evaluate the effectiveness of oral administration of BLFP in relieving clinical signs and altering the intestinal microbiota in diarrheal cats. Six out of eight diarrheal cats showed clinical improvement after BLFP administration for 7 days, and the stool condition of the other two was normal. A higher Firmicutes/Bacteroidetes ratio was noted in the feces of diarrheal cats without clinical improvement as compared with those in the healthy cats and in the diarrheal cats with clinical improvement after receiving BLFP. The phylum Bacteroidetes and class Bacteroidia decreased significantly in diarrheal cats regardless of BLFP administration. Blautia spp. , Ruminococcus torques, and Ruminococcus gnavus, which belong to the Clostridium cluster XIVa and have been reported as beneficial to intestinal health, increased significantly in feces after treatment. Furthermore, Clostridium perfringens also significantly decreased in diarrheal cats after BLFP administration. Overall, BLFP could be a potential probiotic to relieve gastrointestinal symptoms and improve fecal microbiota in cats with chronic diarrhea.
Exploring the Experience of Traveling to Familiar Places in VR: An Empirical Study Using Google Earth VR

Abstract Considered to be an emerging topic in tourism research, traveling to familiar places benefits both the travelers and destinations. However, the current development of familiar tourism is severely affected by the epidemic. Recognizing the potential of virtual reality (VR), this research aims to explore VR’s relevance in the application of visiting familiar places and the empirical features of VR beyond on-site familiar tourism. We first reviewed the literature and developed an experience framework. Secondly, we conducted an exploratory activity in which participants (N = 16) used Google Earth VR to travel to their familiar places with two conditions (free exploration and task-oriented travel). In the activity, we employed think-aloud protocols, a scale, and semi-structured interviews. With our framework, we categorized findings into five dimensions and indicated the similarities and differences between familiar tourism in VR and that in actual places. Particularly, three empirical features (the sense of distance, multi-view space, and montage time) were recognized and formed VR’s opportunity to outperform on-site travel. We conclude by discussing the impacts of VR on familiar tourism and providing implications, including designing the timeline, sounds, tasks, and virtual guides. These suggestions inspire designers to acknowledge VR limitations and identify directions for future tourism applications. As a beginning of empirical investigation on VR familiar tourism, this study opens up a new field of discussion around VR tourism experience. We invite the Human-Computer Interaction (HCI) community to collectively probe into the VR experience and design of visiting familiar places. Efforts in this area will stretch beyond the current understandings of various forms of tourism and contribute to crafting rich travel experience by immersive technologies.
Are There Differences between Estimate (Theoretical) and Actual MACC Approaches of Emission Reduction?

The global warming phenomenon has become an international issue which requires effort to avoid and control the concentration of greenhouse gases (GHGs). At the same time, despite various attempts, developed countries need to put more effort and attention into dealing with this issue. Many studies have been conducted on reducing GHGs globally and nationally. The majority of these studies have focused at a national or sectorial level, particularly in the industrial sector. This study focuses on stationary energy. There are two main ways to reduce GHGs, particularly CO2. One is to replace carbon-based fuels with renewables. The other is to reduce consumption. To achieve further GHG emission reductions, improvements to regarding the use of energy are an emerging area of research that has significant implications for policy. Quantitative and qualitative research methodologies were used for this research. The findings of this research indicate that organisations are seeking a more accurate approach to save energy, reduce emissions, and determine the impact of users. ’ Organisations are planning to use management accounting methods such as Marginal abatement cost curves (MACCs) when measuring the cost of abatement or reduction in environmental costs for more effective decision-making. This study developed a concept by using actual data in MACC. The design established support for organisations to meet data accuracy needs.
Recent Advances in Monitoring Stem Cell Status and Differentiation Using Nano-Biosensing Technologies

In regenerative medicine, cell therapies using various stem cells have received attention as an alternative to overcome the limitations of existing therapeutic methods. Clinical applications of stem cells require the identification of characteristics at the single-cell level and continuous monitoring during expansion and differentiation. In this review, we recapitulate the application of various stem cells used in regenerative medicine and the latest technological advances in monitoring the differentiation process of stem cells. Single-cell RNA sequencing capable of profiling the expression of many genes at the single-cell level provides a new opportunity to analyze stem cell heterogeneity and to specify molecular markers related to the branching of differentiation lineages. However, this method is destructive and distorted. In addition, the differentiation process of a particular cell cannot be continuously tracked. Therefore, several spectroscopic methods have been developed to overcome these limitations. In particular, the application of Raman spectroscopy to measure the intrinsic vibration spectrum of molecules has been proposed as a powerful method that enables continuous monitoring of biochemical changes in the process of the differentiation of stem cells. This review provides a comprehensive overview of current analytical methods employed for stem cell engineering and future perspectives of nano-biosensing technologies as a platform for the in situ monitoring of stem cell status and differentiation.
Impact of Online Learning on Gifted Students

This paper presents the findings from a study conducted to explore the impact of the COVID-19 pandemic and subsequent school closures on the wellbeing of gifted students and their attitudes towards online (distance) learning. The impact of the COVID-19 pandemic circumstances on the parents of gifted children was also explored in this study. Data collection was via semi-structured interviews with gifted students (n = 25) and parents of gifted students (n = 10). This study found that school closures and home isolation resulted in gifted students and their parents experienced a heightened sense of burdened and an increase in the tension within the family. Additionally, changes in the psychological wellbeing of the gifted students were observed. COVID-19 has had a significant disruptive effect on the routines of gifted students, restricting their capacity to move freely and causing them to experience adverse outcomes including sleeping difficulties, loneliness, lack of motivation, and a sense of helplessness. Gifted students also reported generally negative attitude towards online learning, describing it as inadequate, inefficient, and limited in its opportunities to promote student interaction and discussion. This paper also includes suggestions on how support for gifted students can be improved to help them to achieve to their potential both during and after the pandemic.
Study of Iran–Saudi Arabia Sports Relations

Political tensions and conflicts have been accompanying modern sports for a long time. The objective of this study was to determine the political reasons for not hosting football matches between Iranian and Saudi football teams. To address the research objective, a mixed-method approach was used. First, in the qualitative part, the political reasons for not hosting the matches identified through the content analysis and interviews were reviewed and evaluated by Delphi Group (25 people) in the second and third stages. Secondly, in the qualitative section of the study, the questionnaire was also used to rank the reasons. The research findings showed that tensions between Tehran and Riyadh increased after the Saudi Embassy attack in Tehran and Mashhad (January 2016) and the execution of Sheikh Nimr, a Shia sheikh opposed to the Saudi government. Saudi Arabia has requested that the Asian Champions League matches against Iranian opponents be held on neutral grounds in order to ensure the safety of its players. It is therefore recommended that sports managers and politicians in Iran reduce the political tensions between the two countries. In addition, they need to strive toward creating peace, friendship, and security between the two countries.
Investigation of the Hydrodynamic Characteristics of Two Manta Rays Tandem Gliding

Collective motion is a unique biological habit of manta rays. As the most basic unit, the hydrodynamic mechanism of tandem gliding deserves further study. In this paper, a numerical simulation method was used to explore the influence of the front-to-back distance and the angle of attack on the overall and individual hydrodynamic performance of a pair of manta rays gliding. Specifically, a numerical simulation of the hydrodynamic parameters and the distribution of pressure and velocity fields was carried out when the pair of manta rays were arranged at a distance of 0.25–1 times the body length and the angle of attack was −8° to 8°. The simulation results show that, when a pair of manta rays glide at close range, compared to a single manta ray gliding, the resistance of the leader is greatly reduced, and the lift changes little, while the resistance of the follower is greatly increased, and the lift is significantly reduced. For the average resistance of the system, in the specific scenario of a close range and a small negative degree angle of attack, the two manta rays’ tandem gliding system can significantly reduce the resistance and play a role in reducing resistance and saving energy. The research content of this paper provides a theoretical basis for understanding the biological habits of manta rays and designing an underwater bionic robot group system.
Fruit Development, Maturation, Ripening, and Senescence: A Biochemical Basis for Horticultural Terminology1

The terminology used to describe developmental stages of fruits is often confusing or even misleading. “Mature” and “ripe” are often used synonymously. We find reference to “green” fruit, based on skin or peel color, used interchangeably with “unripe”, the latter without referring to pigmentation but rather to a state of non-palatability. We see in the literature such words used synonymously as “overripe” and “senescent” in describing a fruit in a very late stage of development. Such terms as “early maturity”, “optimum maturity”, or “full maturity” leave some doubt as to what stage is actually under consideration. At best, different authors are not always referring to the same stage, even when dealing with the same fruit.
What Happened During COVID-19? Instructional Setting as a Predictor of Students’ Academic Achievement

Our goal in the current study was to identify the degree to which instructional setting (remote versus traditional) predicted students’ academic achievement during the COVID-19 pandemic. A matched sample of data from 194 undergraduate students who were continuously enrolled at a private university in the southeastern United States from the spring semester of 2020 through the spring semester of 2021 was selected for this study. Data from students enrolled remotely across 37 majors were matched by sex, enrollment status, and Spring 2020 GPA. Our findings showed that neither instructional setting, students’ sex, nor the number of hours they attempted were important predictors of students’ academic performance during the COVID-19 pandemic. Furthermore, the academic performance of students enrolled remotely on average remained unchanged from Spring 2020 through Spring 2021. Incidentally, our results revealed that the preceding academic performance was the only important predictor of students' academic achievement during this period. This finding confirms former research on the role that previous performance plays in the academic performance of undergraduate students.
