Authors: Wang Yueru , Chen Xiaoyan , Lu Zhikai , Lai Chunlin
Published: May 2022

BACKGROUND: Compelling evidence demonstrated that circular RNAs (circRNAs) were involved in the progression of atherosclerosis (AS). However, the role of circ_0093887 in the progression of AS is unclear. The purpose of this study was to explore the role and mechanism of circ_0093887 in oxidized-low density lipoprotein (ox-LDL)-induced human aortic endothelial cells (HAECs). METHODS: HAECs were stimulated by ox-LDL to simulate AS-like injury in vitro. Circ_0093887, microRNA-758-3p (miR-758-3p), and BMP And Activin Membrane-Bound Inhibitor (BAMBI) levels were detected by quantitative real-time polymerase chain reaction (qRT-PCR). PCNA, Bax, Bcl-2, and BAMBI protein levels were detected by western blot. Cell viability and apoptosis were examined by Cell Counting Kit-8 (CCK-8) assay and flow cytometry. Tube formation assay was used to assess tube formation. The levels of inflammatory factors TNF-α and IL-1β were detected by corresponding ELISA kits. The relationship between miR-758-3p and circ_0093887 or BAMBI was tested via dual-luciferase reporter analysis and RNA immunoprecipitation. Oxidative stress related indexes (ROS and MDA) were detected by corresponding kits. RESULTS: The expression levels of circ_0093887 and BAMBI were prominently downregulated in ox-LDL-induced HAECs compared with control, whereas the expression of miR-758-3p was upregulated. Overexpression of circ_0093887 promoted HAECs viability and tube formation, and restrained cell apoptosis in ox-LDL-induced HAECs compared with untreated HAECs. Mechanistically, circ_0093887 regulated the expression of BAMBI through miR-758-3p. Further experiments showed that upregulation of miR-758-3p reversed changes in cell function induced by circ_0093887. In addition, reduced BAMBI salvaged miR-758-3p knockdown mediated effects on cell function. CONCLUSION: Circ_0093887 demonstrated its diagnostic and therapeutic value in AS by promoting the role of the miR-758-3p/BAMBI axis in the ox-LDL-induced endothelial injury of HAECs.

Authors: Leng Minmin , Sun Yue , Chang Hui , Wang Zhiwen
Published: May 2022

Background: Recognizing the correlations between care problems of people with dementia could help clinicians choose treatment methods because related symptom groups might respond to the same treatment intervention. Objective: This study aimed to evaluate the prevalence of various care problems in people with dementia and to explore the core care problems and correlations between care problems of people with dementia. Methods: This cross-sectional study recruited family caregivers of people with dementia through memory clinics and WeChat groups. Care problems of people with dementia were measured using a care problems evaluation sheet, which involved three aspects: daily living care problems, behavioral and psychological symptoms, and safety risks. Clustering analysis of the care problems based on Kruskal’s minimum spanning tree (MST) algorithm was performed in the Jupyter Notebook software to explore the core care problems and their correlations. Results: A total of 687 carer-patient pairs were included in the analysis. In general, the prevalence of having difficulty in language performance, agitated behavior, and incidence of falls was relatively higher than other care problems in people with dementia, which distressed their family caregivers. Through clustering analysis, the 63 care problems were clustered into 7 clusters and 7 core care problems were identified. Conclusion: The prevalence of various care problems of people living with dementia in China was relatively high. The information regarding correlations in clusters among care problems will help practitioners and policymakers to identify the core care problems and optimize more rational treatments for people with dementia.

Authors: Bouchareb Ilhem
Published: May 2022

A significant advance has been made in medical diagnosis through introduction of mathematical theories and artificial intelligence (AI). The main theme of this research work is to presents a novel arteries unblocks sensor model based on the principle of the propagation electromagnetic waves. Sensor model based on an electromagnetic waves transmit shock waves through guide wires to specifically cross calcified and fibrotic tissues in the arterial vascular system while leaving intact the elastic wall of healthy vessels. This sensor model has been implemented in a designed system model in an electric circuit inside stockings. The observed results are presented to illustrate the performances of his ability to move strange objects which represents the suspended cholesterol. The results expressed by the distance traveled by the stone under the influence of electromagnetic waves transmitted in water showed that the application of this principle for a period of time allows the opening of blockage of the arteries which demonstrates the performance of the proposed sensor model and the entire system. For health state monitoring: severity and localization coordinates of the arteries unblocks by incorporating artificial intelligence tools are studied in detail in second part for better obstruction treatment.

Published: May 2022

To solve the problems of the Bouc-Wen model with multi-identification parameters, low accuracy, complex methods, and difficulty in implement, this study proposes a new way for parameter identification of the Bouc-Wen model of the magnetorheological (MR) damper by parameter sensitivity analysis and modified PSO algorithm. The one-at-a-time method (OAT) of local sensitivity analysis is utilized to analyze the unknown parameters in the Bouc-Wen model to complete the model simplification. Then, the modified PSO algorithm is used to identify the parameters of the simplified Bouc-Wen model. Finally, with the relationship between the currents and identified parameters, a Bouc-Wen model for current control is constructed by the curve fitting method. The results confirm that the parameter identification efficiency achieved via the parameter sensitivity analysis is improved by 50% by reducing the parameters of the Bouc-Wen model from 8 to 4. Then, compared with the standard PSO (SPSO) algorithm, the modified one is accurate and stable, and the convergence speed is increased by 17.65% on average. At last, compared with the test data under three different sinusoidal excitations, the model’s accuracy is 89.11%, 92.56%, and 87.45%, respectively. The method proposed in this research can rapidly and accurately identify the Bouc-Wen model and lays a theoretical foundation for applying the MR damper model in vibration control.

Authors: Mishra Amit Kumar , Bhardwaj Ramakant , Joshi Nisheeth , Mathur Iti
Published: May 2022

This paper aims to select the appropriate node(s) to effectively destabilize the terrorist network in order to reduce the terrorist group’s effectiveness. Considerations are introduced in this literature as fuzzy soft sets. Using the weighted average combination rule and the D–S theory of evidence, we created an algorithm to determine which node(s) should be isolated from the network in order to destabilize the terrorist network. The paper may also prove that if its power and foot soldiers simultaneously decrease, terrorist groups will collapse. This paper also proposes using entropy-based centrality, vote rank centrality, and resilience centrality to neutralize the network effectively. The terrorist network considered for this study is a network of the 26/11 Mumbai attack created by Sarita Azad.
Portfolio selection model with triangular intuitionistic fuzzy number by rate of return
Authors: Xiaolian Liao , Guohua Chen
Published: May 2022

A portfolio selection model with return as triangular intuitionistic fuzzy number is developed in this study to assess and select portfolios on China Stock Exchange. Although the portfolio selection has been widely investigated, and most studies have regarded return and risk as the main decisive criteria, there are many uncertainties in the financial market, such as social, political and human psychological factors, which makes it difficult for us to describe the risks in line with empirical evidence. To fill this gap, first, a literature review was conducted to clarify the current situation and shortcomings of portfolio selection. Second, the triangular intuitionistic fuzzy number was used to fuzzify the coefficients of the objective function and the constraints in the portfolio model. Third, the triangular intuitionistic fuzzy number model was transformed into a linear programming model by using the selected exact ranking function, and the model was solved by MATLAB. Finally, the historical monthly returns of 10 stocks in China’s Stock Exchange from December 2017 to November 2020, lasting 36 months, were selected to demonstrate the model. The results indicate that the portfolio selection model with triangular intuitionistic fuzzy number can better meet the uncertainty of the real securities market, and more reasonable investment decision guidance can be provided for investors. Besides, the limitations of this study are pointed out, and implications and directions for future research are discussed.

Published: May 2022

Background: As the international community dealt with the ongoing COVID-19 pandemic, important progress continued to be made in the development of new drug-based therapies for the neurodegenerative condition of Parkinson’s disease (PD) in 2021. This progress included both “symptomatic treatments” (ST – improves/reduces symptoms of the condition) and “disease modifying treatments” (DMT - attempts to delay/slow progression by addressing the underlying biology of PD), which can be categorised further based on their mechanisms of action and class of drug. Objective: This report continues previous efforts to provide an overview of the pharmacological therapies - both ST and DMT - in clinical trials for PD during 2021– 2022, with the aim of creating greater awareness and involvement in the clinical trial process. We also hope to stimulate collaboration amongst all stakeholders, including industry, academia, advocacy organizations, and most importantly patient community. Methods: We conducted a review of clinical trials of drug therapies for PD using trial data obtained from the ClinicalTrials.gov and World Health Organisation (WHO) registries, and performed a breakdown analysis of studies that were active as of January 31st 2022. We also assessed active drug development projects that had completed one clinical phase but were yet to start the next. Results: There was a total of 147 clinical trials registered on the ClinicalTrials.gov website as active during the period of analysis. Of these trials, 91 (62%)were investigating STs, while 56 (38%)focused on DMTs. Approximately 1/3 of the studies (34.7%; 51 trials) were in Phase 1, while over half of the trials were in Phase 2 (50.3%; 74 trials). Only 15% (22 trials) of the studies were in Phase 3, of which only 3 trials were evaluating DMTs. Novel therapeutics (42%)were the most common type of agents being tested across all phases of testing, followed by repurposed agents (34%)and reformulations (20%). Conclusion: Despite significant global health constraints, the development of new drug-based therapies for PD continued in 2021. Hopefully with a shift towards a post-pandemic world in which COVID-19 is better managed, we will see an increase in the number of clinical trials focused on drug development for PD. The need for more Phase 3 studies for DMTs remains acute.
Walking activities beyond gait training: Priorities in everyday life for parents and adolescents in pediatric neurorehabilitation
Authors: Ammann-Reiffer Corinne , Graser Judith V.
Published: May 2022

PURPOSE: This study aimed to gain knowledge about which walking-related everyday life activities and situations are relevant for parents of children with a neuromotor disorder and adolescents undergoing inpatient neurorehabilitation. METHODS: Two focus group interviews with purposive samples were performed, one with seven parents of children with acquired or congenital neuromotor disorders, and one with four adolescents undergoing inpatient neurorehabilitation. Data were analyzed with a qualitative descriptive research approach. RESULTS: Parents identified 120 activities that they considered as relevant in their everyday life and the adolescents identified 113 activities. Based on these activities, ten different categories that have a direct relation to walking in everyday life were identified. “Dealing with obstacles,” “moving in public areas,” “moving in a group,” and “walking in general” were perceived as the highest priority categories by the focus group participants. CONCLUSION: Activities incorporating walking tasks related to moving in a group or public areas and dealing with obstacles are perceived as meaningful by adolescents and parents in their everyday life. Addressing these categories in the goal setting process with families could facilitate the definition of walking-related goals aimed at increasing children’s and adolescents’ independence in daily life.

Authors: Ranganathan Rajiv , Doherty Carson , Gussert Michael , Kaplinski Eva , Koje Mary , Krishnan Chandramouli
Published: May 2022

Background:

Despite tremendous advances in the treatment and management of stroke, restoring motor and functional outcomes after stroke continues to be a major clinical challenge. Given the wide range of approaches used in motor rehabilitation, several commentaries have highlighted the lack of a clear scientific basis for different interventions as one critical factor that has led to suboptimal study outcomes.

Objective:

To understand the content of current therapeutic interventions in terms of their active ingredients.

Methods:

We conducted an analysis of randomized controlled trials in stroke rehabilitation over a 2-year period from 2019-2020.

Results:

There were three primary findings: (i) consistent with prior reports, most studies did not provide an explicit rationale for why the treatment would be expected to work, (ii) most therapeutic interventions mentioned multiple active ingredients and there was not a close correspondence between the active ingredients mentioned versus the active ingredients measured in the study, and (iii) multimodal approaches that involved more than one therapeutic approach tended to be combined in an ad-hoc fashion, indicating the lack of a targeted approach.

Conclusion:

These results highlight the need for strengthening cross-disciplinary connections between basic science and clinical studies, and the need for structured development and testing of therapeutic approaches to find more effective treatment interventions.
Bolt loading effects on the structural integrity assessment of defects in industrial components
Authors: Scheepers Ronnie , Bezuidenhout Marthinus
Published: May 2022

Applied loads in bolted geometries of safety critical components can vary with time and operating conditions. Structural integrity and remaining life assessments of such components in aging industrial plants must consider the resultant changes in damage accumulation rates and acceptable defect sizes. Two case studies are presented that demonstrate the effect of bolt pre-load on creep and fatigue lives as well as on the acceptability assessments of defects. In the first case the sensitivity of creep damage accumulation and crack propagation rates to bolt pre-load in high temperature flanged connections are considered. Predicted results were found to compare well with actual damage quantified on a high pressure turbine loop pipe flange connection. It was shown that decreased pre-loads, in this case, leads to an increase the allowable safe defect size during assembly at room temperature. In contrast to this the second case study of corrosion fatigue cracking in a boiler water circulating pump illustrates that an increase in bolt pre-load leads to an increase in fatigue initiation life, a decrease in fatigue crack propagation rate and an increase in the acceptable defect size. Strain gauge measurements of bolt and casing strain, which correlated well with finite element calculations, indicated the necessity for close control of bolt pre-load during assembly to ensure specified levels are attained. In both cases metallurgical analysis and structural integrity assessments of cracked and excavated geometries were conducted which enabled limited continued operation of the components after which repairs and/or replacements will be implemented.

Published: May 2022

Research concerning heat-resistant steels for the application in fossil-fired power plants has progressed remarkably during the past 60 years. This has resulted in improvements in the electrical efficiency of fossil-fired power plants. Currently, there are plans and programs to develop ultra-supercritical plants designed to operate at steam temperature and pressure conditions of 600/650 °C and 32 MPa. The W-added 9%Cr ferritic heat-resistant steel, that is, ASME grade P92, has been developed as a boiler material for this ultra-supercritical plant. Boiler materials, whose performance is critical for ultra-supercritical plant, are required to possess high creep resistant properties. In addition, these materials are exposed to fatigue induced by thermal stresses, that is, they are operated under creep-fatigue interacting conditions. In this study, mechanical tests under the condition of high temperature creep-fatigue interaction were conducted for P92 steel under stress-controlled and various load frequency conditions using the in-situ observational creep-fatigue testing machine to observe the damage formation behavior around a notch tip composed of voids in mesoscale. On the basis of these results, the effects of damage formation behavior on crack growth life were clarified. Furthermore, for the case of creep deformation, the numerical analyses of vacancy diffusion and concentration around a notch tip were conducted using our proposed numerical method of local stress-induced vacancy diffusion behavior, which is a nanoscale phenomenon to relate these behaviors to the damage formation behavior in mesoscale (μm scale).

Published: May 2022

BACKGROUND: In nursing practice, cognitive failures can be evaluated as an essential indicator of the cognitive capacity of individuals. OBJECTIVES: This study aimed to determine the validity and reliability of the Persian version of the Workplace Cognitive Failures Scale (P-WCFS) among Iranian nurses and its relationship with personality traits. METHODS: Data collection had two phases: 1) The P-WCFS prepared through a standard translation process. Then the content validity was evaluated by a panel of specialists. Reliability Cronbach’s coefficient alpha obtained 0.91 from a pilot study. 2) For measuring neuroticism and conscientiousness used the Goldberg Personality Questionnaire. Exploratory and confirmatory factors analyzed in two separate parts of the sample (n = 351). SPSS (v 18) and STATA 14 performed for Statistical analysis. Spearman correlation and Pearson correlation coefficient used to measuring the convergence and examine the relationship between the subscales of the questionnaire. RESULTS: Cronbach’s alpha was 0.92, which showed a high level of reliability for this questionnaire. The three-factor model of WCFS was well-fitted. The reliability of all three sub-scales was a reasonable level. Cognitive failures and its subscales had negative and strong relationships with conscientiousness and neuroticism. The highest internal consistency was related to memory subscale, and all scales had a success rate of 100%. CONCLUSIONS: This study showed the P-WCFS has high reliability and validity and can be used in nursing society.
Long-term effect of a care manager on work ability for patients with depression – the PRIM-CARE RCT
Authors: Petersson Eva-Lisa , Hange Dominique , Udo Camilla , Björkelund Cecilia , Svenningsson Irene
Published: May 2022

BACKGROUND: Collaborative care with a care manager in primary care improves care. OBJECTIVE: To study whether care manager support leads to improved work ability, decreased job strain and reduced time of sick leave among primary care patients with depression. METHODS: A clinical effectiveness study of care managers for depression patients seeking care in primary care was conducted in a RCT 2014 –2016. Patients in the intervention group were assigned a care manager. In the 12-month follow-up, patients with employment (n = 269; intervention n = 142, control n = 127) were studied concerning work ability, job strain and sick leave. RESULTS: An association was shown between reduction of depressive symptoms and improved work ability for the entire group. At 12-month follow-up a statistically significant difference of reduction of depressive symptoms was seen between the groups (MADRS-S: intervention 10.8 vs control 13.1, p = 0.05) as well as increased quality of life (EQ-5D: intervention 0.77 vs control 0.70, p = 0.04). In the intervention group, a concordance was found between the patient’s prediction of return to work and the actual return to work (91%for intervention and 68 %for control group, p = 0.047). CONCLUSIONS: Compared to usual care, the care manager does not seem to further improve perception of work ability, job strain or perception of social support per se among the patients despite a long-term effect on depression symptoms. The lack of a long-term effect regarding these aspects may be due to the fact that care manager support was only provided during the first three months.
Calling: Never seen before or heard of – A survey among Swiss physicians
Authors: Laura Simões Morgado , Friedrich Stiefel , Mehdi Gholam , Céline Bourquin
Published: May 2022

BACKGROUND: Research is needed to gain a deeper understanding of what motivates physicians to do their work and what keeps them in the profession. OBJECTIVES: To explore calling as an approach to work in a sample of physicians. METHODS: We designed an online survey addressing career choice and career calling among physicians in French-speaking Switzerland, and measured associations between calling and categorical variables (participant characteristics, motivations for choosing medicine, career choice(s) and consistency, and definition of calling). RESULTS: The majority of physicians (n = 229) reported that a calling was not a career motivator. The main reasons for becoming a physician were to be useful (n = 173), the scientific aspects of medicine (n = 168), and altruism (n = 153). Viewing medicine as a calling was significantly associated with having been attracted specifically and only to the medical career and stability of this career choice. Physicians defined a calling as internal summons (n = 140), passion (n = 126), and sense of purpose in life (n = 101). Being in the right place, internal summons, and passion were significantly more often considered as a definition for calling by physicians with a calling. CONCLUSIONS: A sense of calling influences career choice and professional stability, and might play a protective role in exhaustion or dissatisfaction at work.

Published: May 2022

BACKGROUND: Technological progress improves health care efficiency, quality, safety, and cost, supporting clinical activity in various scenarios, such as Intensive Care Unit (ICU). A timely response to alarms from monitors and other ICU electromedical devices is therefore crucial. The number of false alarms tend to desensitize care providers increasing the risk of experiencing alarm fatigue and, at times, lead to severe consequences for patients. OBJECTIVES: To assess the psychometric properties of the Italian version of the Alarm Fatigue Questionnaire and to explore the phenomenon of alarm fatigue among nurses working in intensive care settings. METHODS: The CVI-I was calculated to evaluate the validity of the content of the tool. Construct validity was investigated through exploratory factor analysis. Cronbach’s alpha coefficient (α) was used to examine the internal consistency of the scale and Spearman’s rho coefficient to test for stability. We designed a multicentre cross-sectional survey. A convenience sample of nurses from 4 Major Italian hospitals was recruited. The nurses completed the Italian version of the Alarm Fatigue Questionnaire. RESULTS: The content validity index CVI-S of the scale (CVI-S) was 91.11%; Cronbach’s alpha coefficient was 0.71. The Italian version of the tool explained 67.18%of the overall variance. 396 nurses were enrolled (79.84%). The overall level of alarm fatigue was Me = 29 [22;30]. 42.17%of the sample reported prior experience with alarm fatigue incidents. CONCLUSIONS: The extension of alarm fatigue requires the adoption of a preventive intervention plan. The Italian version of the Alarm Fatigue Questionnaire shows promising psychometric properties.
The impact of workload and job satisfaction on occupational stress – A comparison among newly qualified and experienced midwives
Authors: Jasiński Arkadiusz M. , Derbis Romuald
Published: May 2022

BACKGROUND: Midwives are potentially exposed to high levels of occupational stress. The level of stress may be related to the job demands and job resources, as well as midwife seniority. To date, few studies on the determinants of occupational stress have examined Polish midwives. OBJECTIVE: This study aims to investigate the roles of workload, job satisfaction, and seniority in shaping the stress levels of midwives in Poland. METHODS: A cross-sectional approach and structural equation modeling (SEM) were used to compare two groups: newly qualified midwives (NQMs; n = 79) and experienced midwives (n = 99). All data were collected between January and November 2018. RESULTS: Analysis revealed that in both NQMs (β = 0.34, p = 0.006) and experienced midwives (β = 0.40, p < 0.001) workload was a positive predictor of occupational stress. In contrast, job satisfaction was found to be a negative predictor of stress in both groups (NQMs: β = -0.44, p < 0.001; experienced midwives: β = -0.57, p < 0.001). The study groups did not differ significantly in terms of the levels of workload, job satisfaction, and occupational stress. CONCLUSION: Workload and job satisfaction are predictors of occupational stress in midwives. The results of this study indicate the important role of job satisfaction and workload in the shaping of occupational stress levels. Resource-rich and low-stress work environments can enhance the quality of health care provided by midwives.

Authors: Bernardes Sarah M.F. , Assunção Ana , Fujão Carlos , Carnide Filomena
Published: May 2022

BACKGROUND: The aging of the workforce is changing, but working conditions have not changed at the same exponential growth rate for senior workers. Such a situation can compromise the worker’s physical and cognitive capability, reducing the ability to perform work activities. OBJECTIVES: This study aims to understand the main functional capacity changes in senior workers in the automotive industry and to determine the contribution of working conditions on the decline of the functional capacity in senior workers. METHODS: To achieve the objectives of the study, a set of questionnaires (Sociodemographic Data, COPSOQ, Nordic Questionnaire, and Par-Q) and a battery of 4 functional capacity tests were used. Results: Work conditions, namely awkward postures, force demands and manual material handling, and age, were statistically associated to the functional decline in workers. Additionally, multiple linear regression showed that height, weight, seniority, and strength have predictive value to the handgrip decline (both positions HG2 and HG5). CONCLUSION: These results suggest that workers’ handgrip assessment should be considered as a future measure as an indicator of strength ability in the occupational field.

Охарактеризовано ознаки домашнього насильства. Зроблено висновок про те, що означена дефініція є предметом вивчення багатьох наук, зокрема, соціальною педагогікою. Особливостями досліджуваної проблематики є переважно прихований характер домашнього насильства, системна і довготривала дія кривдника на об’єкт насильства, відсутність певних вікових, соціальних або суспільних рамок. Доведено, що проблема домашнього насильства є однією з найгостріших у сучасному соціумі і водночас має значний історичний бекґраунд.

Temperature dependent isobaric molar heat capacity cP was measured in a containerless way for liquid Ti and two AlTi binary liquid alloys. The technique of electromagnetic levitation was used in combination with laser modulation calorimetry.

In all cases, linear temperature dependencies were found: At the corresponding liquidus temperatures, cP equals 49.75(±2.0) J∙K-1mol-1, 57.43(±2.9) J∙K-1mol-1, and 42.60(±2.2) J∙K-1mol-1, for Ti, Al20Ti80 and Al50Ti50, respectively. The respective temperature coefficients amount to -1.67∙10-2J∙K-2mol-1, -2.73∙10-2J∙K-2mol-1, and +7.83∙10-2J∙K-2mol-1. For liquid Ti, there is a good agreement with existing literature data. The results are discussed in relation to the Neumann-Kopp rule.

El empleo de los recursos educativos de libre acceso resulta insustituible en las experiencias de enseñanza y aprendizaje de los jóvenes universitarios. Este trabajo tuvo como propósito conocer las percepciones de los profesores e investigadores de la Universidad Autónoma del Estado de Morelos, México, con relación al empleo de los recursos educativos abiertos (REA) en las actividades educativas. En la indagación se utilizó un enfoque metodológico cualitativo centrado en estudio de caso y como técnica de captura de información se hizo uso de una guía de entrevista abierta en línea a los profesores e investigadores de las diversas unidades académicas de dicha casa de estudios. Entre otros resultados, en los testimonios de los informantes se reflejó una valiosa disposición para colaborar en la producción, utilización, curaduría y promoción de los REA; de igual modo, calificaron como muy positivo el uso de dichos recursos por parte de los estudiantes pues contribuyen a la motivación y la autonomía en el desarrollo de las actividades de aprendizaje. Finalmente, reconocieron la ausencia de políticas educativas en el uso de los REA en programas institucionales de desarrollo educativo, lo que contraviene las recomendaciones de la UNESCO.

En la actualidad existe un presuroso desarrollo de la electrónica y la microelectrónica, esto ha motivado que todas las esferas de la vida humana se estén automatizando, por ejemplo: la industria, el hogar, los comercios, la agricultura, la ganadería, el transporte, las comunicaciones, etc. En todo ese proceso de automatización el microprocesador y el microcontrolador toman un papel de suma importancia. Estos han permitido el desarrollo de sistemas inteligentes que son capaz de resolver los más diversos problemas, y son los llamados Sistemas de Adquisición de Datos.

El objetivo básico de los Sistemas de Adquisición de Datos es la unificación de los diferentes recursos que lo integran tales como: Transductores, multiplexores, amplificadores, conversores A/D y D/A, de memorias y puertos externos y creando con todo ello un sistema que se encargue de una aplicación específica como por ejemplo, es chequear unas variables (PH, humedad relativa, temperatura, iluminación, tensión eléctricas, concentración, etc ) para una posterior utilización de la misma ya sea con resultados para docentes, científicos, de almacenamiento o control y utilización de la misma.

Es por esto por lo que el objetivo principal de este proyecto fue el diseño y la elaboración de un dispositivo de adquisición de datos basado en conversor analógico digital de 16 bits y una etapa de acondicionamiento de bajo ruido, este dispositivo permite obtener, registrar y visualizar la información en un computador para su posterior estudio. La aplicación de este dispositivo puede estar proyectada para realizarse en el campo de la sismología, la medicina, la ingeniería civil, eléctrica o electrónica, etc., por ejemplo, si se deseara utilizar en la sismología, el equipo diseñado cuenta con un sensor magnético el cual podrá registrar y medir las variaciones en los movimientos terrestres ya provengan estos de terremotos o vibraciones provocadas para la exploración sísmica etc, sean de alta o baja magnitud.

Otro campo de aplicación del equipo diseñado puede ser en el registro de actividad electrodérmica, el cual es una técnica no invasiva que se utiliza para estudiar las reacciones corporales a diversos estímulos y tiene múltiples aplicaciones en el campo biomédico (dermatología, endocrinología, psicopatología, neurología, etc.).

Este artículo presenta la implementación de un sistema de adquisición de datos a 16 bits, donde se realizan mediciones de diferentes magnitudes de tensión y en presencia de muy bajo ruido gracias a la electrónica implementada, lo cual hace al dispositivo muy confiable y eficiente. El diseño se ha procurado poder brindar las siguientes características claves: tamaño reducido, conectividad con un ordenador personal, seguridad eléctrica, muy bajo ruido, posibilidad de incorporar nuevas funcionalidades y que sea de bajo costo y fácil adquisición y manipulación.

This article discusses forced vibrations of a rectangular two-layer piecewise homogeneous plate of constant thickness, when the material of the upper layer of the plate is elastic and the other satisfies Maxwell’s model, that is, viscoelastic. The transverse displacement of points of the contact plane of a two-layer plate is determined, which satisfies the approximate equation obtained in [1], replacing only the viscoelastic operators of the upper layer of the plate with the elastic Lames coefficients, respectively. Fluctuation rectangular is free a piecewise-homogeneous plate at nonzero initial conditions, frequencies of own fluctuations are calculated, and the analytical decision of this problem is under construction. The received theoretical results for the decision of dynamic problems of cross-section fluctuation of piecewise homogeneous two-layer plates of a constant thickness taking into account viscous properties of their material allow to count more precisely cross-section displacement of points of a plane of contact of plates at non-stationary external loadings.

TRI-STATE+ COMMUNICATION SYMMETRY USING THE ALGEBRAIC APPROACH
Authors:   Planalto Research, Mountain View, CA, USA, GERCK Edgardo
Published: May 2022

This work uses the algebraic approach to show how we communicate when applying the quantum mechanics (QM) concept of coherence, proposing tri-state+ in quantum computing (QC). In analogy to Einstein’s stimulated emission, when explaining the thermal radiation of quantum bodies in communication, this work shows that one can use the classical Information Theory by Shannon (with two, random logical states only, “0” and “1”, emulating a relay), and add a coherent third truth value Z, as a new process that breaks the Law of the Excluded Middle (LEM). Using a well-known result in topology and projection as a “new hypothesis” here, a higher dimensional state can embed in a lower-dimensional state. This means that any three-valued logic system, breaking the LEM, can be represented in a binary logical system, obeying the LEM. This satisfies QC in behavior, offering multiple states at the same time in GF(3m), but frees the implementation to use binary logic and LEM. This promises to allow indeterminacy, such as contingency, reference failure, vagueness, majority voting, conditionals, computability, the semantic paradoxes, and many more, to play a role in logic synthesis, with a much better resolution of indeterminate contributions to obtain coherence and help cybersecurity. We establish a link between Einstein’s and Shannon’s theories in QM, hitherto not reported, and use it to provide a model for QC without relying on external devices (i.e., quantum annealing), or incurring in decoherence. By focusing on adequate software, this could replace the emphasis in QC, from hardware to software.
