The Iso-Deformation of Images and the Criterion for Delimitation of the Usable Areas in Cine-Auditoriums

The origin of image deformations on screens, real and apparent deformations, and physical and psychic factors are discussed. Apparent deformations due to immobile and mobile images are considered with their respective deformation indexes. Isodeformation curves of mobile and immobile images and their design are described. Even and cylindrical screens are examined and the delimitation of apparent deformations is investigated. The uses of normal screens, wide screens, CinemaScope, Todd-AO-70mm and Cinerama are outlined.
A Review of Innovative Comparator Designs

Three papers on the optimal design of comparator circuits are further analyzed in this work. Each paper presents a method to improve the performance of comparators. Floating inverter amplifier applied an independent capacitor as the source of the preamplifier, which improves the overall performance of the circuit. In another design, a special local clock generator is proposed to control the input of both of the latch stage and the preampliﬁer, which makes it possible to adjust the speed and improve the energy efficiency. In dynamic bias circuit design, stabilized common-mode voltage is realized by adding a capacitor to the tail of the pre-amplifier of a latch-type comparator, optimizing the power and noise performance successfully.
Stagnation points and bifurcation in 3‐D mountain airflow

The effect of non-linearity on the formation of mountain-wave induced stagnation points is examined using the scaling laws for ideal hydrostatic flow and a series of runs with decelerating winds in a numerical model. In the limit of small deceleration rate (i.e., near steady state) runs with a variety of mountain heights and widths give similar results; i.e., the speed extrema values in the 3-D wave fields collapse onto “universal curves”. For a Gaussian hill with circular contours, stagnation first occurs at a point above the lee slope. This result contradicts the result of linear theory that stagnation begins on the windward slope. The critical value of ĥfor stagnation above a Gaussian hill is ĥ crit = 1.1 ± 0.1. For a 3/2-power hill, the critical height is slightly higher, ĥ crit = 1.2 ± 0.2. These values are significantly larger than the value for a ridge (ĥ crit = 0.85), due to dispersion of wave energy aloft. The application of Sheppard's rule and the vorticity near the stagnation point are discussed. As expected from linear theory, the presence of positive windshear suppresses stagnation aloft. With Richardson number = 20 for example, stagnation first begins at the ground at a value of ĥ= 1.6 ± 0.2. When a stagnation point first forms aloft in the unsheared case, the flow field begins to evolve in the time domain and the scaling laws are violated. We interpret these events as a wave-breaking induced bifurcation which leads to stagnation on the windward slope and the formation of a wake. DOI: 10.1034/j.1600-0870.1993. 00003.x
PREGNANT WOMEN EMPOWERMENT IN MONITORING FETAL WELLBEING THROUGH FETAL MOVEMENT COUNT MOBILE APPLICATION

Fetal movement is one of the main indicators of fetal well-being in the womb. For this reason, every pregnant woman should be able to calculate and interpret the results of fetal movement calculations every day, so that early detection of fetal pathology can be identified by the family. Most pregnant women are not used to it and have not received information about how to calculate fetal movement. Another obstacle in calculating fetal movements is the forgetting factor. For this reason, a tool is needed to familiarize mothers with counting fetal movements every day. Existing tools still have some drawbacks. This study aims to develop an android-based application called "Kick Count", as a tool for pregnant women to count fetal movements every day. The research method uses R&D which consists of: exploring potential problems, gathering information, product design, design testing, design improvement, and product testing. The results of product trials by media experts, material experts, and groups of pregnant women state that this product is very suitable for use by pregnant women in the community. Things that still need to be perfected for the next stage are reducing memory and integrating installation instructions into the application.
Serological responses and protection levels in chickens administered with Newcastle disease vaccines

Vaccination against Newcastle disease (ND) is the most effective means of controlling the disease, and these vaccines are commercialized only after their safety and effectiveness have been verified through tests that comply with Korean Standards of National Lot Release for Veterinary Biologics. This study investigated whether a relatively convenient and safe serological test can be used in place of the challenge test using highly virulent ND virus. Hemagglutination inhibition (HI) assay and enzyme-linked immunosorbent assay (ELISA) were considered positive of log2 2 or more and cutoff value of 200 or more, respectively, in both live and inactivated vaccines. However, when the antibody levels of the live and inactivated vaccines induced using the Ulster 2C, KBNP-C4152R2L, and K148/08 strains were compared, the antibody titers for inactivated vaccines were significantly higher than those for live vaccines in both the HI assay and ELISA. A strong positive correlation was observed between HI and ELISA antibody titers. The live vaccines corresponded to a survival rates of ≥ 80% and the inactivated vaccines corresponded to 100% survival rates. This study confirmed that standard efficacy tests can serve as serological tests, and can replace the challenge test and that the vaccine approval process can be improved.
Preconception Care: An Untapped Route towards Reducing Infant and Maternal Mortality in Nigeria

The aim of preconception care is to reduce parental risk factors before pregnancy through health promotion and intervention which reduces maternal and infant morbidity and mortality. Healthcare providers play important roles in providing this care to women and men of childbearing age. In Nigeria however, the implementation of preconception care by healthcare providers remains low. In this review, an overview of preconception care in Nigeria and the barriers that affects its delivery will be explored. Peer reviewed articles were searched using key words related to preconception care and implementation of the care by healthcare providers. Publications were deemed eligible if they reported on preconception care and barriers influencing the provision of preconception care. A careful analysis of existing literatures on the topic shows that, there is a low understanding of preconception care among women of reproductive age in Nigeria. Furthermore, preconception care is not yet widely practiced in the Nigeria as part of health care due to unplanned and recurrent pregnancies, high parity, poor health care seeking behavior and low level of maternal health care. In view of the aforementioned challenges, there is a need to develop and implement preconception policies and guidelines to be applied in the existing health care system. Considering the importance of this care in improving pregnancy and neonatal outcomes, there is a need to educate and engage members of the society as well as health care providers in its importance and delivery.
The electromagnetic property of chemically reduced graphene oxide and its application as microwave absorbing material

The residual defects and groups in chemically reduced graphene oxide cannot only improve the impedance match characteristic and prompt energy transition from contiguous states to Fermi level, but also introduce defect polarization relaxation and groups’ electronic dipole relaxation, which are all in favor of electromagnetic wave penetration and absorption. The chemically reduced graphene oxide shows enhanced microwave absorption compared with graphite and carbon nanotubes, and can be expected to display better absorption than high quality graphene, exhibiting a promising prospect as microwave absorbing material.
Direct path planning in image plane and tracking for visual servoing

The image-based visual servoing would lead to image singularities that might cause control instabilities, and there exit other constraints such as the object should remain in the camera field of view and avoid obstacles. This problem can be solved by coupling path planning and image-based control. The trajectory is planned directly in the image space in our strategy to avoid the 3D estimation of the object, which is required in the motion space based path planning method. In the presented method, the initial path is given using the artificial potential field method without considering the constraints and then genetic algorithm based method is used to check and modify the initial path. This method can achieve satisfactory task while decrease the computation. The proposed method is used to align the micro peg and hole, and the simulation results show that the object can reach its desired position accurately without violation these constrains.
Recent progress in electron probe microanalysis

Electron probe microanalysis (EPMA) is a fairly mature analytical technique which has been widely used in the fields of geochemistry and materials science since the early 1960s. The 1980s and early 1990s or so have seen dramatic improvements, both theoretical and experimental, in the accuracy with which the concentrations of light elements such as oxygen can be measured by EPMA. This has coincided with a resurgence of interest in mixed-valence oxides which was stimulated by the discovery of high temperature superconductivity, and EPMA is now a vital tool for condensed matter physicists working in this field. Stoichiometric characterization is particularly important in the area of thin films, and a great deal of work has been devoted to modifying existing EPMA correction procedures in order to perform analyses of thin film or layered specimens. The present article reviews the progress that has been made from a physicist's perspective, paying attention to the levels of accuracy and precision which are now attainable, and to the advantages and disadvantages of EPMA in relation to other analytical techniques.
Theoretical and experimental investigation of optically driven nanoelectromechanical oscillators

The actuation of biologically functional micro- and nanomechanical structures using optical excitation is an emerging arena of research that couples the fields of optics, fluidics, electronics, and mechanics with potential for generating novel chemical and biological sensors. In our work, we fabricated nanomechanical structures from 200 and 250 nm thick silicon nitride and single crystal silicon layers with varying lengths and widths ranging from 4 to 12 μm and 200 nm to 1 μm, respectively. Using a modulated laser beam focused onto the device layer in close proximity to the clamped end of a cantilever beam, we concentrate and guide the impinging thermal energy along the device layer. Cantilever beams coupled to chains of thermally isolated links were used to experimentally investigate energy transport mechanisms in nanostructures. The nature of the excitation was studied through steady-periodic axisymmetric thermal analysis by considering a multilayered structure heated using a modulated laser source. Res.

Shallow decay of X-ray afterglows in short GRBs: Energy injection from a millisecond magnetar?

With the successful launch of Swift satellite, more and more data of early X-ray afterglows from short gamma-ray bursts have been collected. Some interesting features such as unusual afterglow light curves and unexpected X-ray flares are revealed. Especially, in some cases, there is a flat segment in the X-ray afterglow light curve. Here we present a simplified model in which we believe that the flattening part is due to energy injection from the central engine. We assume that this energy injection arises from the magnetic dipole radiation of a millisecond pulsar formed after the merger of two neutron stars. We check this model with the short GRB 060313. Our numerical results suggest that energy injection from a millisecond magnetar could make part of the X-ray afterglow light curve flat.
Fundamental Properties of “Homogeneous” Multifractals*

It is proven from the requirement of scale-similarity of multifractals that the probability of spatial distribution of a certain measure supported by a multifractal, which may be called intrinsic probability, is uniquely determined for a scale ratio tending to zero if the f -α spectrum of the multifractal is given. As a corollary, it is proven that there exists no nonlinear transformation of multifractals. Also, it is derived that intrinsic probabilities of many multifractals including multinomial generalized Cantor sets can be determined by the knowledge of intermittency exponents µ( q ) (and then generalized dimensions D ( q )) limited for q =nonnegative integers only.
Time reversal duality between linear networks

In time reversal duality, pairs of networks have corresponding waveforms that are time reversed versions of each other. The relation linking a pair of generalized, nonlinear, time varying dynamical systems is derived. It is then applied to time invariant linear networks. Four types of time reversal circuit duality are possible, and in two of these the direction of energy flow is reversed.

Arquitectura distribuida modular para el control inteligente del tráfico

La gestión de la movilidad de personas y vehículos es un aspecto de continuo estudio debido a la relevancia que tiene en la contribución a la polución. El control de los semáforos determina las colas que en los cruces se pueden formar. Habitualmente este control no está adaptado al tráfico existente en un momento concreto, dado que la adaptación implica conocer los peatones y vehículos que se encuentran circulando en cada momento. Para resolver este problema, en el artículo se propone el uso de unos dispositivos inteligentes modulares que permiten detectar los vehículos y cambiar los tiempos de acceso al cruce dependiendo de las circunstancias. Para validar el sistema se ha realizado una simulación generando cargas en MatLab y simulando el control con Simulink. Se ha simulado un ciclo de semáforo con tiempos fijos y se ha comparado con ciclos de tiempos variables en función de la carga de peatones y de vehículos. En el artículo se proponen los indicadores Op y Sat como método de medición de la optimización del algoritmo de control sobre el estado del cruce. Por medio de dichos indicadores se ha comprobado que en el mejor de los casos es posible optimizar en un 50 % el tiempo de espera de forma casi independiente de la carga de tráfico.
Employee voice: a knowledge map to provide conceptual clarity and future research directions

The increasing globalisation, the multiculturality of workplaces and the current challenges for organisations generated the need for researchers to support them to manage the workforce. Although the relevance of employee voice for these themes, a lack of shared understanding about this topic results in fragmented literature across and within research fields that limits theoretical advancement and deep comprehension of the phenomenon. Our first aim is to offer a literature review of employee voice by combining systematic and bibliometric methods; the second aim is to understand voice's main issues and implications by considering different research streams. The results present an integrated framework of the leading intellectual knowledge and reveal the main research focuses on voice in domestic contexts. The discussion underlines the cultural issue and context as critical elements for future research by proposing avenues for scholars and some implications for organisations to benefit from the contributions of their members.
An alternative approach of Kirsch-Kress method for reconstructing the shape of a sound-soft obstacle from several incident fields

The inverse problem we consider is to reconstruct the shape of a plane acoustically sound-soft obstacle from the knowledge of the far-field patterns for several incident fields. An alternatively iterative procedure is proposed based on the numerical method which was developed by Kirsch and Kress. For several incident fields, a computational technique with its corresponding iterative method is presented to reduce the amount of computation by the superposition of the single-layer potential and of the far-field equation. Numerical examples show that the methods give accurate numerical approximations in relatively few iterations for several incoming waves.
Medication Adherence Among Patients of Type II Diabetes Mellitus and Its Associated Risk Factors: A Cross-Sectional Study in a Tertiary Care Hospital of Eastern India

Background: Type 2 diabetes mellitus is a major public health problem. Adherence to anti-diabetic medications improves glycaemic control, which in turn prevents complications as well as reduces out-of-pocket expenditure. The World Health Organization highlights that the impact of interventions directed to improve adherence has far greater implications than specific medical interventions. There are several factors that contribute to poor adherence. Not many studies have been conducted to explore adherence to diabetes medications in eastern India. Objectives: To measure medication adherence among patients suffering from diabetes. To determine the various risk factors influencing adherence to medication. To find out the association of health-related quality of life with adherence to medication. Methodology: A hospital-based cross-sectional study was conducted in the outpatient Department of General Medicine and Endocrinology of a tertiary care hospital in eastern India from January to March 2020. Adult subjects, who were diagnosed with type 2 diabetes mellitus for at least six months, were interviewed using a pretested, structured questionnaire containing 8-item Morisky Medication Adherence Scale (MMAS-8) to determine adherence to diabetic medications. Data were analysed in SPSS version 27 (IBM Corp., Armonk, NY, USA). Results: The mean age of the 331 participants interviewed was 53.40 (SD 11.0) years and the majority were males (57.1%). Medication adherence of 34.14% (n=113) was found among the subjects. Having any comorbidity, positive family history of diabetes and the habit of current alcohol intake increased the odds of poor adherence by 3.26 times, 1.88 times, and 2.35 times respectively in binary logistic regression analysis. Those following a diabetic diet had a protective effect, decreasing poor medication adherence by 79.6%. Poor medication adherence increased by 1.077 times with every one-day increase in unhealthy days. Conclusion: The medication adherence was 34.14% and as compared to other similar studies medication adherence in the study population was poor and was associated with unhealthy days.
Turnover Intention Review: The Influence Of Organizational Justice And The Work Environment

This research is based on the gap phenomenon encountered by researchers in the field. The purpose of the current study is to determine how much influence organizational justice and work environment have on turnover intention. This type of research is a quantitative research using a survey approach. In this study, data were collected through a questionnaire method with a sample of 356 respondents from private company employees in Bengkulu City. The results showed that organizational justice (x1) was proven to have a greater influence on turnover intention when compared to the work environment (x2), which were 22.2% and 12.4%, respectively, with a significant negative direction. The results of the regression analysis test are formulated with the equation Y = 10.480 - 0.222 (X1) - 0.124 (X2)
Is being able to walk to the letterbox life-changing? A qualitative assessment of measures of improvement in persistent breathlessness

Persistent breathlessness is a prevalent cause of disability in COPD [1]. Many people with COPD do not achieve acceptable symptom control despite optimisation of disease-specific and nonpharmacological treatments [2]. Regular, low-dose, sustained-release morphine may reduce persistent breathlessness in some people, noting wide interindividual variation in benefits and harms. Ideally, sustained-release morphine should only be prescribed to people who are likely to experience a net benefit. To date, the clinicodemographic characteristics of people most likely to benefit from sustained-release morphine for persistent breathlessness have not been defined. Benefits quantified need to reflect people's perceptions [3]. Exploring clinically meaningful measures of improvement for people with persisting breathlessness https://bit.ly/3WaCzFh
Control and compression of extreme spectrally-broadened pulses in highly nonlinear fiber

Nonlinear pulse compression techniques are of course very well-known, exploiting the initial spectral broadening and temporal compression phase of higher-order soliton evolution in the anomalous dispersion regime of an optical fiber. However, the presence of effects such as Raman scattering, higher-order dispersion or input pulse noise can induce pulse break-up and instabilities through soliton-fission processes. Recent studies of soliton fission in the context of supercontinuum generation have provided improved insight into the way these processes can be avoided, allowing significant improvement in achievable compressed pulse quality and duration. In this paper we focus on providing an overview of a series of our own experiments around 1550 nm where we have used parabolic pulse similariton amplifiers to generate low noise pulses that have been linearly and nonlinearly compressed to the sub-30 fs regime using controlled compression in highly nonlinear fiber. In addition, we also describe recent results where comparable pulse durations have been obtained using sub-10 cm lengths of highly nonlinear fiber directly spliced to the output pigtail of a commercial femtosecond source.
