Stress Prediction and Detection Using IoT and Deep Learning: A Comprehensive Review

Abstract: Stress is the part of life that is an unpleasant emotional state that individuals experience in situations like working for long hours ahead of a computer. Stress is often positive, but it can affect your health if it's chronic. Also Stress is a characteristic response to different pressure instigating factors which can prompt physiological and conduct changes. On the off chance that continues for a more extended period, stress can cause destructive consequences for our body. The body sensors alongside the idea of the Internet of Things can give rich data about one's psychological and actual wellbeing. The proposed work focuses the mind level and identifies enthusiastic changes that happened in an individual when he/she is under pressure, melancholy, or uneasiness. On recognizing, A hint message will be sent to their relatives so that they will assist that individual with emerging from his/her circumstances to fostering an IoT framework which can proficiently identify the anxiety of an individual and give an input which can help the individual to adapt to the stressors.

Effects of Diabetes Mellitus on the Reproductive System of Adult Male Mice After One Cycle of Spermatogenesis

Background: Diabetes mellitus is a disease characterized by chronic hyperglycemia. Poor management of hyperglycemia leads to complications that can reduce quality of life. Diabetes mellitus has been associated with damage to the reproductive system. The present study examines effects of diabetes mellitus on the reproductive system in alloxan-induced diabetic mice after one cycle of spermatogenesis. Materials and Methods: Twelve (12) mice divided into "control" and "diabetic" groups of six (6) animals each were used. Diabetes was induced in adult male mice by intraperitoneal injection with a single dose of 220 mg/kg body weight of alloxan. After 40 days, sperm density, morphology, and motility were assessed by standard methods. Serum levels of testosterone, FSH, and LH were measured. In addition, testes and epididymis were removed for histological study. Results: Highly significant (P < 0.001) reductions in serum testosterone, FSH, and LH levels, as well as normal and motile sperm counts of 21% and 34% respectively were observed in the diabetic group. The control group had three times more sperm than the diabetic group. The histological increased inter-tubular spaces, loss of interstitial tissue, degeneration of seminiferous tubules, and almost complete reduction of sperm count in the epididymal duct. Conclusion: Chronic hyperglycemia is therefore deleterious to the male reproductive system of mice. It leads to hypogonadism, which causes dysfunction of the male reproductive system, and can lead to infertility in men with diabetes mellitus.
General relativity effects in precision spin experiments on tests of fundamental symmetries

A search for the $P$- and $CP(T)$-violating electric dipole moments (EDM) of atoms, particles and nuclei with sensitivity up to $10^{-15}$ in units of magnetic dipole moments, allowed by all discrete symmetries, is one of the topical problems of modern physics. According to Sakharov, $CP$-violation is one of the three key criteria of baryogenesis in generally accepted paradigm of the Big Bang cosmology. All three criteria are supported by the Standard Model (SM), but it fails to describe the observed baryon asymmetry of the Universe. This is regarded a strong argument in favor of existence of $CP$-symmetry breaking mechanisms beyond minimal SM, which can lead to measurable EDMs of atoms, particles and nuclei. Direct searches for EDM of charged particles and nuclei are possible only in storage rings (COSY, NICA). After successful studies by the JEDI collaboration at the COSY synchrotron, at the forefront is a search for the proton EDM in an electrostatic storage ring with the proton spin frozen at the magic energy with projected sensitivity $d_p\sim 10^{-29}\,e\cdot$cm. Following a brief introduction to the $CP$-violation physics and the baryogenesis, the review presents a detailed discussion of significant contributions to the spin dynamics from the terrestrial gravity along with the new effects of Earth's rotation in ultrasensitive searches for the EDM of charged particles and neutrons. Quite remarkably, for the projected sensitivity to the proton EDM, these false EDM effects can by one to two orders of magnitude exceed the signal of the proton EDM, and become comparable to an EDM contribution in experiments with ultracold neutrons. We also discuss the role of a precessing spin as a detector of the axion-like dark matter, and consider applications of the quantum gravitational anomalies to the dense matter hydrodynamics and the spin phenomena in the non-central nuclear collisions.
Tip-Enhanced Raman Spectroscopy of 2D Semiconductors

Two-dimensional (2D) semiconductors are one of the most extensively studied modern materials showing potentials in large spectrum of applications from electronics/optoelectronics to photocatalysis and CO2 reduction. These materials possess astonishing optical, electronic, and mechanical properties, which are different from their bulk counterparts. Due to strong dielectric screening, local heterogeneities such as edges, grain boundaries, defects, strain, doping, chemical bonding, and molecular orientation dictate their physical properties to a great extent. Therefore, there is a growing demand of probing such heterogeneities and their effects on the physical properties of 2D semiconductors on site in a label-free and non-destructive way. Tip-enhanced Raman spectroscopy (TERS), which combines the merits of both scanning probe microscopy and Raman spectroscopy, has experienced tremendous progress since its introduction in the early 2000s and is capable of local spectroscopic investigation with (sub-) nanometer spatial resolution. Introducing this technique to 2D semiconductors not only enables us to understand the effects of local heterogeneities, it can also provide new insights opening the door for novel quantum mechanical applications. This book chapter sheds light on the recent progress of local spectroscopic investigation and chemical imaging of 2D semiconductors using TERS. It also provides a basic discussion of Raman selection rules of 2D semiconductors important to understand TERS results. Finally, a brief outlook regarding the potential of TERS in the field of 2D semiconductors is provided.
The preferred leadership styles in vocational training corporations: Case of Jordan

The study aims to identify the leadership styles (democratic, authoritative, autocratic, laissez-faire, transformational, and transactional) practiced by trainers at the Vocational Training Corporation as perceived by the female trainees in Jordan. Descriptive statistics were used to analyze the data collected by the questionnaire from respondents (n = 105 female trainees) selected by the simple randomization sampling and representing 50% of the population (n = 210). Among the questionnaires sent, only 104 were received and declared valid for statistical analysis. Major findings indicated that the democratic leadership style was mostly preferable by female trainees, where rated top by respondents (M = 4.50), followed by the transformational style (M = 4.23), and the authoritative style was rated the lowest (M = 2.58) compared with the autocratic, laissez-faire and transactional leadership styles. Thus, to keep increasing the development of training programs and obtain positive feedback for trainees, both trainers and managers of the Vocational Training Corporation necessarily need to practice appropriate leadership styles, develop a high level of learning and benefits.

Operation of portable HF CDMA networks with controlled transmitter powers

The use of networks consisting of portable HF radios multiplexed to a master station requires an effective supervision system. Spread-spectrum code-division multiple access provides flexibility in the number of users and has advantages over time and frequency multiple-access techniques for this type of network in that precise time or frequency co-ordination between the users is not needed. However, possible near-far problems due to other-user interference and the desire to reduce the peak power in order to reduce the detectability to nonmembers of the network make it necessary to enforce control of the transmitter powers. It is shown that when the transmitter powers are well controlled the added power required to combat the other-user interference is small for a wide range of network users. As the control gets less accurate or no control is applied, the added power required owing to multiplex operation becomes larger, and ultimately no increase in power will save the network from degrading. The controlled transmitter power scheme is applied both to networks of ground-wave links and to networks of sky-wave links. For the ground-wave links it may be assumed that a propagation parameter is represented by one number, as compared with sky-wave links, where the parameters are time varying and are best described by statistical distributions.
Remote query fluid-flow velocity measurement using magnetoelastic thick-film sensors (invited)

The characteristic resonant frequency of a thick-film ribbon-shaped magnetoelastic sensor is dependent upon its length, density, Poisson’s ratio, and modulus of elasticity [J. M. Barandiaran and J. Guitierrez, Sens. Actuators A 59, 38 (1997)]. In a manner analogous to surface acoustic wave (SAW) sensors, this characteristic resonant frequency also changes with effective mass load or with friction force applied to the surface of the magnetoelastic sensor [L. D. Landau and E. M. Lifshitz, Theory of Elasticity, 3rd ed. (Pergamon, New York, 1986), Chap. II]. The time varying magnetic flux emitted from magnetoelastic sensors can be monitored remotely using pickup coils. Hence, in contrast with SAW devices, no direct physical connections are required to obtain magnetoelastic sensor information, allowing them to be monitored from within sealed, opaque containers. Reported here is application of magnetoelastic sensors to the measurement of fluid flow from within sealed pipes. Within the laminar fluid flow regime .
Modelling the Past and Future Evolution of Tidal Sand Waves

This study focuses on the hindcasting and forecasting of observed offshore tidal sand waves by using a state-of-the-art numerical morphodynamic model. The sand waves, having heights of several meters, evolve on timescales of years. Following earlier work, the model has a 2DV configuration (one horizontal and one vertical direction). First, the skill of the model is assessed by performing hindcasts at four transects in the North Sea where sand wave data are available of multiple surveys that are at least 10 years apart. The first transect is used for calibration and this calibrated model is applied to the other three transects. It is found that the calibrated model performs well: the Brier Skill Score is ‘excellent’ at the first two transects and ‘good’ at the last two. The root mean square error of calculated bed levels is smaller than the uncertainty in the measurements, except at the last transect, where the M2 is more elliptical than at the other three transects. The calibrated model is subsequently used to make forecasts of the sand waves along the two transects with the best skill scores.
Real-time lane detection for autonomous vehicle

A lane detection based on a road model or feature needs correct acquisition of information on the lane in an image. It is inefficient to implement a lane detection algorithm through the full range of an image when it is applied to a real road in real time because of the calculation time. This paper defines two search ranges of detecting a lane in a road. First is the searching mode that searches the lane without any prior information of a road. Second is recognition mode, which is able to reduce the size and change the position of a searching range by predicting the position of a lane through the acquired information in a previous frame. It is allowed to extract accurately and efficiently the edge candidate points of a lane without any unnecessary searching. By means of inverse perspective transform that removes the perspective effect on the edge candidate points, we transform the edge candidate information in the image coordinate system (ICS) into the plane-view image in the world coordinate system (WCS). We define a linear approximation filter and remove faulty edge candidate points by using it. This paper aims to approximate more correctly the lane of an actual road by applying the least-mean square method with the fault-removed edge information for curve fitting.
Skanda (Bala Graha) and Cerebral Palsy – A Review

Among the Ashtanga Ayurveda, Kaumarbhritya focuses on child care in particular. Graharogais the most neglected portion due to excess mythological explanation, difficulty in clinical understanding, diagnosis, severity, complication, and treatment is entirely different from the routine disorder of children. Graharogas are those entities that attack and seize the body then affect the neonates and children very quickly with high mortality. Different acharyas describe Graha with their types, symptoms and treatment. Acharya Sushruta and Acharya Vagabhatta describe Skanda graha- commander-in-chief of the army of Devatas. The symptoms of the affected child resemble very much with Quadriplegic Cerebral Palsy. Cerebral palsy (CP) is the leading cause of childhood disability affecting function and development. The motor disorders of cerebral palsy are often accompanied by disturbances of sensation, perception, cognition communication, and behavior. Therefore, this paper aims to understand Balagraha with the modern aspect as well as its clinical application in day-to-day practice.
The dependence of electromagnetic energy absorption upon human head tissue composition in the frequency range of 300-3000 MHz

The requirements for testing compliance of cellular phones with electromagnetic safety limits demand evaluation of the maximum exposure that may occur in the user group under normal operational conditions. Under these conditions, the tissues of the ear region are most exposed, the tissue composition of which is complex and varies considerably from user to user. The objective of this paper is to derive head tissue equivalent dielectric parameters that enable the utilization of one generic homogeneous head for testing compliance for the entire user group, i.e., granting no underestimation, but also not greatly overestimating the actual maximum user exposure. As a primary study, a simple analytical model of an infinite half-space layered tissue model exposed to a plane wave was utilized to investigate the impact of impedance matching standing waves, etc. On the spatial-peak specific absorption rate. The tissue layers were varied in composition and thickness, representing the anatomical variation of the exposed head region covering the user group including adults and children ( 90% percentile). Based on the worst-case tissue layer compositions with respect to absorption at each frequency, head tissue equivalent dielectric parameters for homogeneous modeling were derived, which result in the same spatial-peak absorption. The validity of this approach for near-field exposures was demonstrated by replacing the plane wave by different near-field sources (dipoles and generic phones) and the layered structure with magnetic-resonance-image-based nonhomogeneous human head models.
The impact of COVID-19 on university students’ academic motivation, social connection, and psychological well-being.

The COVID-19 pandemic has significantly disrupted our daily lives. Public health officials are encouraging restrictions on social gatherings, limiting the amount of time and number of people individuals can interact with in-person. However, people have an innate need for belonging, and social isolation can exacerbate psychological distress. Due to school closings, students have shifted to online learning, which may foster feelings of detachment from their respective schools and impact students' motivation to continue learning in an online context. In the present study, we surveyed N = 238 undergraduate students to assess the relationships between academic motivation, sense of belonging to their university, and COVID-19-related distress. Correlational analyses revealed positive relationships between academic motivation and sense of belonging, and negative relationships between these two variables and COVID-19-related distress. A multiple linear regression demonstrated that sense of belonging and socioeconomic status negatively associated with COVID-19-related distress. Believing that online learning is as effective as in-person learning did not moderate the relationship between the sense of belonging and academic motivation. We discuss implications for colleges and universities to improve students' psychological well-being. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
Experimental Investigation of Pedestrian Personal Space

New generations of computer-based simulations of pedestrian crowd dynamics are aimed at improving both scientific knowledge about such complex social phenomena and practical use of the results for more efficient, safer management of pedestrian circulation dynamics in urban scenarios. Within this twofold framework, the validation of the developed models with field data plays a central role, and the acquisition of empirical evidence about human behavior during locomotion is mandatory. An empirical investigation of pedestrian personal space (i.e., the area surrounding an individual while walking and into which strangers cannot intrude without causing discomfort) is reported. The investigation was developed in an ad hoc experimental setting to collect meaningful data (e.g., measurements of the front zone of personal space under static and moving conditions). The main results are presented to illustrate both the adopted experimental setting and the related data-collection method. These results represent an innovative contribution toward defining a metric for the characterization of spatial interactions among pedestrians and allowing the validation of simulation models dedicated to the study of the dynamic behavior of pedestrian crowd phenomena.
The future of the Asian auto industry: regional integration, alternative designs, and Chinese leadership

This paper provides a critical analysis of the key drivers behind the future of the automotive industry in Asia. It argues that three changes will condition the evolution of the Asian auto sector. First, the Asian region will rapidly progress towards an integrated market and, as a whole, will play a central role in the global automotive industry. Second, alternative vehicle designs specific to the emerging Asian markets can be expected to emerge and form a second tier market. Political and economic advantages exist for the bodies of these vehicles being of fiber-composite resin materials instead of the steel of traditional vehicles. Finally, China will increasingly play a leadership role in the region, driving the regional economic integration process and establishing itself as critical base and destination for automakers and suppliers. The paper also addresses the evolving regional division of labor in Asia and how differences across countries, automakers, and suppliers may play a role in the emerging context.

VIBRATION ANALYSIS OF TURBINE BASED ON FLUID-STRUCTURE COUPLING

The vibration of a Francis turbine is analyzed with the additional quality matrix method based on fluid-structure coupling (FSC). Firstly, the vibration frequency and mode of blade and runner in air and water are calculated. Secondly, the influences to runner frequency domain by large fow, small flow and design flow working conditions are compared. Finally the influences to runner modes by centrifugal forces under three rotating speeds of 400 r/min, 500 r/min and 600 r/min are compared. The centrifugal force and small flow working condition have greatly influence on the vibration of small runner. With the increase of centrifugal force, the vibration frequency of the runner is sharply increased. Some order frequencies are even close to the runner natural frequency in the air. Because the low frequency vibration will severely damage the stability of the turbine, low frequency vibration of units should be avoided as soon as possible.
ELABORACIÓN DE UN PRODUCTO CÁRNICO ESCALDADO UTILIZANDO COMO EXTENSOR HARINA DE FRÍJOL COMÚN (Phaseolus spp.) ELABORATION OF A SCALDED SAUSAGE USING COMMON BEAN FLOUR (Phaseolus spp.) AS EXTENDER

The use of extenders in the meat industry seeks to replace meat protein in general by vegetal protein from leguminous raw materials easily obtainable with the aim to reduce production costs. In this work was used flour from common bean (Phaseolus spp.) variety Sabanero as an extender, at concentrations of 3%, 6% and 9% for the elaboration of Frankfurt type sausages. The results showed that when the extender concentration was increased, the product lightness increased, the red color decreased and that shear force and hardness increased but adhesiveness and elasticity diminished. Sensory analysis showed greater acceptance by the consumer of the control samples (without extender) followed by the 3% treatment.
