Published: May 2020

AbstractWe consider an elliptic variational-hemivariational inequality 𝓟 in a reflexive Banach space, governed by a set of constraintsK, a nonlinear operatorA, and an elementf. We associate to this inequality a sequence {𝓟n} of variational-hemivariational inequalities such that, for eachn∈ ℕ, inequality 𝓟nis obtained by perturbing the dataKandAand, moreover, it contains an additional term governed by a small parameterεn. The unique solvability of 𝓟 and, for eachn∈ ℕ, the solvability of its perturbed version 𝓟n, are guaranteed by an existence and uniqueness result obtained in literature. Denote byuthe solution of Problem 𝓟 and, for eachn∈ ℕ, letunbe a solution of Problem 𝓟n. The main result of this paper states the strong convergence ofun→uinX, asn→ ∞. We show that the main result extends a number of results previously obtained in the study of Problem 𝓟. Finally, we illustrate the use of our abstract results in the study of a mathematical model which describes the contact of an elastic body with a rigid-deformable foundation and provide the corresponding mechanical interpretations.

AbstractThe study aims to examine the risk factors for increased colorectal cancer (CRC) markers in patients with type 2 diabetes mellitus (T2DM). The 229 patients retrospectively reviewed were categorized into two groups: CRC tumor marker-positive and -negative groups. Patients who tested positive for all three of the following CRC markers were included in the CRC tumor marker-positive group: serum carcinoembryonic antigen, carbohydrate antigen 19-9 and septin9 methylation. Univariate analysis revealed that most CRC marker-positive patients had higher age, a family history of CRC, history of smoking and alcohol intake, high body mass index (BMI; overweight), longer history of T2DM, worse diabetes control (with high glycated hemoglobin A1c [HbA1c]), lower level of serum vitamin D (VD), high-density lipoprotein cholesterol and higher level of total cholesterol and triglyceride (TG). Logistic regression analysis showed that BMI, VD, HbA1c and TG were independent predictors of CRC marker-positive status (OR, 95% confidence intervals and P values were 1.912 [1.346–2.716], <0.001; 0.773 [0.633–0.943], 0.011; 9.082 [3.52–23.433], <0.001; and 11.597 [3.267–41.164], <0.001, respectively). In this retrospective study, high BMI, HbA1c and TG as well as low level of VD were correlated with CRC tumor marker-positive status in T2DM patients. Patients with these risk factors may benefit from more frequent screening for CRC tumor markers.

AbstractA transfemoral prosthesis is required to assist amputees to perform the activity of daily living (ADL). The passive prosthesis has some drawbacks such as utilization of high metabolic energy. In contrast, the active prosthesis consumes less metabolic energy and offers better performance. However, the recent active prosthesis uses surface electromyography as its sensory system which has weak signals with microvolt-level intensity and requires a lot of computation to extract features. This paper focuses on recognizing different phases of sitting and standing of a transfemoral amputee using in-socket piezoelectric-based sensors. 15 piezoelectric film sensors were embedded in the inner socket wall adjacent to the most active regions of the agonist and antagonist knee extensor and flexor muscles, i. e. region with the highest level of muscle contractions of the quadriceps and hamstring. A male transfemoral amputee wore the instrumented socket and was instructed to perform several sitting and standing phases using an armless chair. Data was collected from the 15 embedded sensors and went through signal conditioning circuits. The overlapping analysis window technique was used to segment the data using different window lengths. Fifteen time-domain and frequency-domain features were extracted and new feature sets were obtained based on the feature performance. Eight of the common pattern recognition multiclass classifiers were evaluated and compared. Regression analysis was used to investigate the impact of the number of features and the window lengths on the classifiers’ accuracies, and Analysis of Variance (ANOVA) was used to test significant differences in the classifiers’ performances. The classification accuracy was calculated using k-fold cross-validation method, and 20% of the data set was held out for testing the optimal classifier. The results showed that the feature set (FS-5) consisting of the root mean square (RMS) and the number of peaks (NP) achieved the highest classification accuracy in five classifiers. Support vector machine (SVM) with cubic kernel proved to be the optimal classifier, and it achieved a classification accuracy of 98.33 % using the test data set. Obtaining high classification accuracy using only two time-domain features would significantly reduce the processing time of controlling a prosthesis and eliminate substantial delay. The proposed in-socket sensors used to detect sit-to-stand and stand-to-sit movements could be further integrated with an active knee joint actuation system to produce powered assistance during energy-demanding activities such as sit-to-stand and stair climbing. In future, the system could also be used to accurately predict the intended movement based on their residual limb’s muscle and mechanical behaviour as detected by the in-socket sensory system.

AbstractObjectivesIn this study, the performance of OpenBCI, a low-cost bio-amplifier, is assessed when used for 3D motion reconstruction.MethodsEleven scalp electrode locations from three subjects were used, with sampling rate of 125 Hz, subsequently band-pass filtered from 0.5 to 40 Hz. After segmentation into epochs, information-rich frequency ranges were determined using filter bank common spatial filter. Simultaneously, the actual hand motions of subjects were captured using a Microsoft Kinect sensor. Multimodal data streams were synchronized using the lab streaming layer (LSL) application. A modified version of an existing multiple linear regression models was employed to learn the relationship between the electroencephalography (EEG) feature input and the recorded kinematic data. To assess system performance with limited data, 10-fold cross validation was used.ResultsThe most information-rich frequency bands for subjects were found to be in the ranges of 5 – 9 Hz and 33 – 37 Hz. Hand lateralization accuracy for the three subjects were 97.4, 78.7 and 96.9% respectively. 3D position reconstructed with an average correlation coefficient of 0.21, 0.47 and 0.38 respectively along three pre-defined axes, with the corresponding average correlation coefficients for velocity being 0.21, 0.36 and 0.25 respectively. The results compare favourably with a cross-section of existing results, while cost-per-electrode costs were 76% lower than the average per-electrode cost for similar systems and 44% lower than the cheapest previously-reported system.ConclusionsThis study has shown that low-cost bio-amplifiers such as the OpenBCI can be used for 3D motion reconstruction tasks.
Non-noble metal based broadband photothermal absorbers for cost effective interfacial solar thermal conversion

Published: May 2020

Abstract
In recent years, noble metal-based solar absorbers have been extensively studied as their pronounced plasmonic resonances and high solar-to-thermal conversion efficiency. However, the high cost of noble metals is the unavoidable roadblock restricting the way towards scalability. In this work, we report a nickel-based photothermal absorbers, which is capable of realizing an average solar absorption of ∼97% in the range of 400–2500 nm originating from relatively weaker collective plasmonic resonances but more pronounced single electron excitation. Importantly, it is easily fabricated via the straightforward physical deposition and cost-effective with a raw material price of ∼0.3% gold and ∼20% of silver. We used it for interfacial solar vapor generation and realized an evaporation rate of ∼0.9 kg m−2 h−1 under one sun, almost comparable to the counterparts made from noble metals. The excellent performance combined with the cost effective and scalable fabrication process makes it be a promising candidate for mass off-grid solar desalination.
Virtuality and the Problem of Agency in Object-Oriented Ontology
Authors: Baranovas Ruslanas 
Published: May 2020

AbstractIn hisPrince of Networks, Graham Harman reconstructs Latourian critique of concepts of potentiality and virtuality with which he claims to agree. This seems striking because Latour’s arguments seem to be exactly those Harman rejects in his other writings as overmining. Furthermore, this critique of potentiality and virtuality creates a dividing line between Harman and Bryant’sDemocracy of Objects, where the concept of virtual plays a central role. In this article, I will explore this debate, focusing on how the concept of virtuality works in the context of the ontological realism that Object-Oriented Ontology is. To do this, I will first present Bryant’s notion of virtuality focusing on the problem of the individuality of the object. Then I will explore Latourian–Harmanian arguments against virtuality and show that the main issue Harman has with virtuality has to do with the agency of objects. Therefore, I claim that the main dividing line between Bryant’s and Harman’s versions of Object-Oriented Ontology is the difference between the two notions of agency.
Synthetic cell-permeable caveolin-1 scaffolding domain peptide activates phagocytosis of Escherichia coli by regulating Rab5 activity
Authors: Hagiwara Makoto , Matsushita Kenji 
Published: May 2020

Abstract
Caveolae are defined as 50–100 nm wide pits in the plasma membrane containing oligomeric caveolin proteins. They have been implicated in endocytosis (including phagocytosis), transcytosis, calcium signalling, and numerous other signal transduction events. Caveolin-1, a major structural component of caveolae, enhances Rab5 activity. In this study, we examined the effect of a synthetic cell-permeable peptide of the caveolin-1 scaffolding domain (CSD) on phagocytosis. Treatment with the CSD peptide increased Rab5 activity, Rab5-early endosome antigen 1 (EEA1) interaction, and phagocytosis of Escherichia coli. The results suggest that the synthetic cell-permeable CSD peptide is an activator of phagocytosis.

Published: May 2020

Background: Hypertension is one of the main modifiable risk factors for cardiovascular disease morbidity and mortality. Pharmacological and lifestyle modification approaches are used in the treatment and management of hypertension. The purpose of this study was to identify lifestyle modification advice provided to the general population and to those diagnosed with hypertension by health care providers (HCP) in Kenya.Methods: A secondary data analysis of cross-sectional data collected among 4500 Kenyans participating in the 2015 Kenya stepwise approach to surveillance study was conducted. Questions related to the consumption of salt, sugar, fat, fruits and vegetables as well as physical activity and weight management were evaluated.Results: Among all the participants, only 12.5%, 20.7%, 12.2%, 10.7%, 10.3% and 11.6% were advised to either reduce salt intake, eat 5 or more servings of fruits and vegetables, reduce fat intake, reduce intake of sugary beverages, lose or maintain weight and start or do more physical activity respectively. Of those diagnosed with HTN, 37% were advised to increase intake fruits and vegetables, 37%, 27% and 25% were advised to reduce, salt, fat and sugary beverages intake respectively, 21% and 22% were advised to start or do more physical activity and maintain a healthy body weight or lose weight respectively.Conclusions: Majority of Kenyans had not received dietary modification advice from HCP despite this being a policy recommendation in Kenya. Policy makers need to work closely with HCP to develop appropriate policy implementation strategies.
Demographic profile of pregnant women and effect of anaemia in gestational diabetes mellitus: a cross sectional study from rural Assam
Authors: Chanda Subrata , Singh Amarjeet 
Published: May 2020

Background: In Assam, gestational diabetes mellitus (GDM) screening is not routinely done during antenatal check-up in Assam, whereas anemia screening is done. Consequently, state-wide GDM estimate and its association with anemia in rural Assam is not available. Hence, we aim to study the demographic profile of pregnant women and their anaemia in relation to prevalence of gestational diabetes mellitus in rural Assam.Methods: The present study was part of a larger community based cross-sectional study, conducted in Assam to determine the prevalence of GDM. The pregnant women in the gestational age of 24-28 weeks, who were free of any chronic illnesses, screened for Anaemia and, GDM through oral glucose tolerance test (OGTT) as per diabetes in pregnancy study group in India guideline.Results: A total of 1212 pregnant women underwent the OGTT and test for haemoglobin estimation. Mean age of GDM women was (24.40±4.60 years), slightly higher than non-GDM women (23.50±4.04 years, p=0.007). After hemoglobin estimation, 83% of pregnant women found to be anaemic, 77% of these were GDM positive, which is quite significant with p value 0.025. A higher fraction of the pregnant mothers in our study were found suffering from anemia (83%). The independent association of GDM and anemia adjusted for other variables showed an inverse relationship.Conclusions: Though prevalence of anaemia and GDM in low resource setting in rural Assam found to be quite high, but they have inverse relationship. Anaemic pregnant women were found to be GDM protective.

Background: Tuberculosis (TB) ranks as the leading cause of death from infectious disease. The World Health Organization (WHO) has considered TB a global public health disaster since 1993. Four factors affect non-adherence to treatment-the patient, healthcare systems, pharmaco-therapeutics and the key persons, health care professional (HCP). So, the study was conducted to evaluate knowledge, attitudes and practices regarding TB care and control in HCPs working in TB units.Methods: This was a cross-sectional, observational, questionnaire-based study conducted in all the HCPs working for the TB care and control.Results: The responses to the questions of knowledge were variable indicating incompleteness of information, facts, understanding related to TB in HCPs. HCPs show very strong positive attitude for finding every new case of TB is essential. The HCPs disagree to some statements like traditional or alternative medicine assists in wellbeing of TB patients. Practice competency was low with average score 2.32 out of 6, doctors having higher score of 4.62 followed by nurses, lab-technicians, pharmacist and activist with score of 2.57, 1.66, 1.5, 1.25 respectively. The activist are the key persons in the national tuberculosis program, exhibited the least score in this study indicates they do not have much orientation about the practice of TB treatment. Specific deficiencies existed for some knowledge statements of HCWs on TB. There was disagreement in attitudes regarding stigma and traditional medicine, and practice competencies were poor. Improvement in aspect of KAP of HCPs on TB will help India achieve the goal of End TB.Conclusions: Specific deficiencies existed for some knowledge statements of TB in paramedical staff as compared to doctor participants. There was disagreement in attitudes regarding stigma and traditional medicine, and practice competencies were poor in activists. Improvement in knowledge, attitude and practices of TB in paramedical staff by conducting CME, Workshop, training sessions will help India to achieve the goal of End TB.
COVID 19 and rural India: better now than later
Authors: Naik Gitismita , Kumar M. Mohan 
Published: May 2020

COVID 19 is devastating lives worldwide and India is no exception. Government of India on 15th April classified districts as hotspots or red zones (123 districts with large outbreaks and 47 with clusters) and non-hotspots or orange zones (207 districts). This leaves more than 300 of the country’s 731 districts which are not yet affected by the pandemic, classified as non-infected districts or green zones. Of India’s 1.21 billion people, about 376 million people live in the districts now classified as green zones and while 68.8% of India’s population lives in rural areas (Census 2011), the share of rural population in the green zones is relatively higher at 84%. This stands true across big states, Kerala being the only exception. It is this proportion of population who has to be protected in the battle against COVID 19 to ultimately emerge victorious and limit any further spread.

Authors: Mora Restrepo Reinaldo 
Published: May 2020

Las características socioeconómicas y raciales, además, de algunas entidades patológicas asociadas con el embarazo, pueden modificar la curva de crecimiento del D.B.P., razones que justifiquen que cada institución hospitalaria elabore una curva aplicable a su población.Se elaboró una curva de crecimiento del D.B.P. basados en 840 determinaciones en 523 pacientes del Hospital Universitario Ramón González Valencia, con ciclos regulares de 26 a 30 días, sin patología materna o fetal concomitante con el embarazo, con fecha cierta de la última regla y sin la ingestión de anticonceptivos en los tres meses anteriores a la misma. Las determinaciones se hicieron entre las semanas 13 y 42 de la gestión.El crecimiento semanal del D.B.P. fue de 3,38 mm entre las semanas 13 y 29, de 2.1 mm entre las semanas 30 y 37 y de sólo 0.64 mm entre las semanas 38 y 42. Nuestros hallazgos son similares a los de otros estudios, confirmándose que la velocidad de crecimiento del D.B.P. es más rápida en el segundo trimestre.
