Metapuf: a challenge response pair generator

Physically unclonable function (PUF) is a hardware security module preferred for hardware feature based random number and secret key generation. Security of a cryptographic system relies on the quality of the challenge-response pair, it is necessary that the key generation mechanism must unpredictable and its response should constant under different operating condition. Metastable state in CMOS latch is undesirable since it response becomes unpredictable, this feature used in this work to generate a unique response. A feedback mechanism is developed which forces the latch into the metastable region; after metastable state, latch settle to high or state depends on circuit internal condition and noise which cannot be predicted. Obtained inter hamming variation for 8 PUF is 51% and average intra hamming distance is 99.76% with supply voltage variation and 96.22% with temperature variation.

Early diagnosis of tuberculosis using deep learning approach for iot based healthcare applications

In the modern world, Tuberculosis (TB) is regarded as a serious health issue with a high rate of mortality. TB can be cured completely by early diagnosis. For achieving this, one tool utilized is CXR (Chest X-rays) which is used to screen active TB. An enhanced deep learning (DL) model is implemented for automatic Tuberculosis detection. This work undergoes the phases like preprocessing, segmentation, feature extraction, and optimized classification. Initially, the CXR image is preprocessed and segmented using AFCM (Adaptive Fuzzy C means) clustering. Then, feature extraction and several features are extracted. Finally, these features are given to the DL classifier Deep Belief Network (DBN). To improve the classification accuracy and to optimize the DBN, a metaheuristic optimization Adaptive Monarch butterfly optimization (AMBO) algorithm is used. Here, the Deep Belief Network with Adaptive Monarch butterfly optimization (DBN-AMBO) is used for enhancing the accuracy, reducing the error function, and optimizing weighting parameters. The overall implementation is carried out on the Python platform. The overall performance evaluations of the DBN-AMBO were carried out on MC and SC datasets and compared over the other approaches on the basis of certain metrics.

Sorting of human mesenchymal stem cells by applying optimally designed microfluidic chip filtration

Human bone marrow-derived mesenchymal stem cells (hMSCs) consist of heterogeneous subpopulations with different multipotent properties: small and large cells with high and low multipotency, respectively. Accordingly, sorting out a target subpopulation from the others is very important to increase the effectiveness of cell-based therapy. We performed flow-based sorting of hMSCs by using optimally designed microfluidic chips based on the hydrodynamic filtration (HDF) principle. The chip was designed with the parameters rigorously determined by the complete analysis of laminar flow for flow fraction and complicated networks of main and multi-branched channels for hMSCs sorting into three subpopulations: small (<25>40 μm) cells. By focusing with a proper ratio between main and side flows, cells migrate toward the sidewall due to a virtual boundary of fluid layers and enter the branch channels. This opens the possibility of sorting stem cells rapidly without damage. Over 86% recovery was achieved for each population of cells with complete purity in small cells, but the sorting efficiency of cells is slightly lower than that of rigid model particles, due to the effect of cell deformation. Finally, we confirmed that our method could successfully fractionate the three subpopulations of hMSCs by analyzing the surface marker expressions of cells from each outlet.

Investigating students’ attitudes toward poverty and impoverished persons - a case study: ho chi minh city open university, data of vietnam

Efforts to understand the causes of poverty, how poverty is perceived have become important in the fight to mitigate poverty. In Vietnam, studies on the attitudes of poverty in specific populations, such as Vietnamese students, are rare. Thus, this dataset reports the results collected from 180 social work students and non-social work students of Ho Chi Minh City Open University through attitudes toward poverty and poor people in Vietnam. The Attitude toward Poverty Short Form 21-item scale, developed by Yun & Weaver, was used for the data collection. The survey results showed that when looking for causes of poverty, social work students and non-social work students put the most emphasis on structural factors of poverty. However, social work students, compared with non-social work students, consider personal deficiency and stigma more important. In future, this dataset can serve as a reference source for comparative studies on student’ attitudes toward poverty and impoverished persons and for social work education

Evaluation of four trichoderma spp. for the biological control of black bundle disease (cephalosporium acremonium) in maize

Four Trichoderma species with known biocontrol activity (T. harzianum, T. hamantum, T. viride and T. virens) were tested for their efficacy against Cephalosporium acremonium, a causal organism of Black bundle disease in maize. Interactions between the fungi were assessed in vitro to study mutual antagonisms. Among the four bio-agents, T. hamantum proved to be promising which showed maximum inhibition (51.3%) followed by T. virens (45.2%), T. harzianum (44.6%) and T. viride (20.3%). T. hamantum was also found to be hyperparasite on C. acremonium whereas, T. harzianum and T. viride showed mycelial deformation. The volatile toxicants released by all the Trichoderma spp. were inferior in inhibiting the growth of C. acremonium when compared to the control as evident by inverted plate technique. The results of in vivo experiments confirmed the results from the in vitro study and showed that all the four bio-agents significantly reduced the disease incidence of Black bundle disease.

Cryptogenetic ischemic stroke : the role of patent foramen ovale closure

Patent foramen ovale (PFO) is an embryonic interatrialdefect potentially associated withischemic cerebralstrokes. One option is the occlusion of the atrial shunt byendovascular means. This procedure is recommendedfor patients with a history of cryptogenic strokes.Patent foramen ovales (PFOs) are common in the general population (prevalence 20-30%) and do not constitute a pathology in their own terms. Nevertheless, a association has been established between the occurrence of certain cryptogenic ischemic strokes and the presence of a PFO. The risk appears higher when septal patency is associated with atrial septal aneurysm (ASA). The aim of this presentation is to study the association between the PFO and the occurrence of ischemic stroke, and the benefits of its closure.

Le tafal-djéguélé : une pratique et expression culturelle à l’épreuve des mutations sociales

Le 05 décembre 2012, les pratiques et expressions culturelles liées au balafon des communautés sénoufo du Mali, du Burkina Faso et de la Côte d’Ivoire ont été inscrites sur la Liste représentative du patrimoine culturel immatériel de l’humanité. Le tafal-djéguélé est une pratique et expression culturelle liée au balafon des Sénoufo de Côte d’Ivoire. Deux raisons principales fondent son usage : amener les laboureurs à la houe à se surpasser d’une part, et magnifier les valeurs des senambélé1 d’autre part, notamment celles en rapport avec le labour étant donné que le sénoufo est agriculteur par essence. Toutefois, en raison de certains changements sociaux, le tafal-djéguélése pratique de moins en moins. Cette situation prive le senanw d’aujourd’hui d’un cadre majeur d’enseignement et de diffusion de valeurs, et pose ainsi la question de leur transmission aux générations actuelles et futures. Cet article vise à démontrer comment la faible pratique du tafal-djéguélé empêche de nos jours la transmission de "valeurs- références" en pays sénoufo, mais aussi à proposer des pistes de solutions.

Selection of potential isolates of plant growth promoting rhizobacteria (pgpr) in conferring salt tolerance under in vitro

Salinity is a major environmental stress which has been studied extensively and has its impact on agriculture in the past, present and future. The global importance of salt affected soils can be explained by their wide distribution on all continents covering about 10% of the total land surface. At present, there are nearly 954 million ha of saline soils on earth’s surface. It is extremely difficult to quantify the social and economic costs of salt prone land and water resources. Plant Growth Promoting Rhizobacteria (PGPR) is a group of bacteria that actively colonize plant roots and increase plant growth and yield. They play an important role within the interaction between soil and plant. As plants grow on marginal soils such as saline soils, the importance of the rhizobacteria increases as they mobilize nutrients and provide tolerance ability to the plants. In the present study, an attempt was made and isolated 51 PGPR isolates (Phosphate Solubilizing Bacteria–18; Azotobacter spp.-16 and Azospirillum spp.-17) from different salt affected areas in Tamil Nadu and Puducherry. All the isolates were screened for their efficacy against different sodium salts namely sodium chloride, sodium citrate and sodium sulphate. It was observed that the absorbance of the culture broth grown in salt stress to sodium chloride decreased with increasing concentration of the salt. Similarly decrease in growth pattern in terms of the absorbance was also observed in salt stress to sodium citrate and sodium sulphate.

Bacteriological qualities of sources of domestic water supply and prevalence of typhoid fever in some communities of enugu state, southeast, nigeria: a cross-sectional study

Background: From the public health point of view, the microbiological properties of domestic water supply are the most important parameters of domestic water supply because of the propensity for microbial water-related diseases. In Enugu State, statistics have shown that reported cases of waterborne diseases (including typhoid fever) have been on the increase since 2003. The aim of the study was to determine the bacteriological qualities of domestic water supply and prevalence of typhoid fever in five communities of Enugu State in connection with the rising incidence of typhoid fever in the state. Methods: This was a cross-sectional study of sources of domestic water supply and prevalence of typhoid fever in five rural communities of Ezeagu Local Government Area. 297 copies of structured questionnaire, 10 grab water samples analysed using the membrane filtration method and 227 blood samples collected for Widal test were used to generate the data for the study, analysed as frequency distributions, t-test of means difference and Pearson product moment correlations using MaxStat (version 3.60) statistical software. Results: 2 (40%) of the 5 communities complied with the WHO standard for faecal coliform counts. Prevalence of typhoid fever was high in all the communities (71.4%-100%). Only faecal coliform counts correlated positively and strongly (r=0.69) with prevalence of typhoid fever. Conclusions: Since faecal coliform counts correlated positively and strongly (r=0.69) with prevalence of typhoid fever, improving the bacteriological qualities of domestic water supply may help to reduce the prevalence of typhoid fever.

Intersection of caste and gender based subjugation

One of the unique features of Indian society is prevalence of caste system which was originated thousands of years back to demarcate the people engaged in different occupation or jobs. Initially it was not much rigid but gradually people belonging to upper castes for their own selfish means to maintain their monopoly made this arrangement hereditary and started treating people of lower castes disgracefully. For preservation of this system, people started controlling their women to prevent inter-caste marriages and the concept of endogamy came up. This robbed away many types of freedom from women. For women belonging to lower castes, this situation is worse as they are doubly subjugated on the basis on caste as well as gender. Men belonging to their own caste treat them as secondary beings. This paper throws light on this intersection. How intersection of these two kinds of inequalities place them at the lowest position in Indian society. Dr. B.R. Ambedkar rises as their leader who all his life worked for empowerment of downtrodden section of society. He argues that education is the primary tool for evading these differences among people. He further emphasizes to adopt the concept of exogamy to break the backbone of Indian caste system and to immediately leave a religion or culture which legitimizes such system of inequality among people of the same land.

Risk factors of intracerebral hemorrhage among the young population in qatar: are genetic risk factors involved?

Background: Intracerebral hemorrhage (ICH) has not been widely investigated in young adults. This study aims to describe the risk factors of ICH with a focus on the possible effect of non-modifiable risk factors, such as genetic factors, to assess the ICH outcomes, and to identify the prognostic factors after ICH among young adult patients. Methods: This prospective and observational study was conducted at two hospitals at Hamad Medical Corporation, Qatar, namely Hamad General Hospital and Alkhor Hospital. The study included young patients (16–45 years old) admitted with ICH between January 1, 2015, and December 31, 2018. Results: We examined 238 consecutive young patients with ICH consisting of 212 (89.1%) males and 26 (10.9%) females. The mean age was 37.8±6.23 years. The most common risk factor found in 187 (78.6%) patients was hypertension (HTN), while 19 (8.0%) patients had no obvious risk factors (cryptogenic). The primary site of bleeding was cerebral cortex (lobar) in 107 (44.96%) patients and then basal ganglia in 97 (40.76%) patients. The in-hospital mortality was 19 (8.0%); the National Institutes of Health Stroke Scale >14 on admission (adjusted OR=2.06; 95% CI=1.448–2.938; p<0.001), Barthel index score ≤40 on admission (adjusted OR=1.09; 95% CI=1.015–1.178; p=0.019), and HTN (adjusted OR=0.075; 95% CI=0.008–0.724; p=0.025) were found to be independent predictors of in-hospital mortality by multivariate analysis. A 1-year follow-up showed mortality in 7 (3.2%) patients and no new events in 139 (63.8%) cases. Conclusion: HTN, smoking, and excessive alcohol consumption are important modifiable risk factors for ICH among young patients in Qatar, requiring early identification and treatment to prevent this dangerous type of stroke. In addition, we recommend conducting further studies focusing on the genetic risk factors of ICH among young adults, particularly those with cryptogenic ICH, to identify whether genetic risk factors are involved.

First report of post-vomiting subcutaneous peri-lacrimal drainage system emphysema

Subcutaneous emphysema is defined as a trapped air in tissues under the skin. This entity most often occurs in the chest wall and neck but can infrequently happen in other parts of the body like the orbital area [1]. The main mechanism of subcutaneous emphysema is the traumatic damage of the anatomical air-filled cavities or canals. Most of the rare, reported cases of orbital and periorbital emphysema were described in adults as complications of several types of traumas, including direct trauma, recent or previous surgery [2,3], barotrauma secondary to non-invasive ventilation, such as continuous positive airway pressure therapy [4], and even post forceful noseblowing [5]. In this report, we described the first reported case of post-vomiting subcutaneous emphysema surrounding the medial canthus of the right eye in a 10-year-old boy.
