A SURVEY ON MOVEMENT ANALYSIS (HAND, EYE, BODY) AND FACIAL EXPRESSIONS BASED DIAGNOSIS AUTISM DISORDERS USING MICROSOFT KINECT V2
Year: 2020

Kinect v2 may enhance the clinical practice of autism spectrum disorders (ASD) ASD means disorders of neurodevelopment that lasts a lifetime, which occurs in early childhood and usually associated with unusual movement and gait disturbances. The earlier diagnosis of ASD helps of providing well known of these disorders. The methods which are adopted by experts in diagnosis are expensive, time consuming, and difficult to replicate, as it is based on manual observation and standard questionnaires to look for certain signs of behavior. This paper, to the best of our knowledge, is a first attempt to collect the previous researches of the Kinect v2 in the disorder's diagnosis. Relevant papers are divided into four groups which are: (1) papers suggest a system based on the analysis of facial expressions, (2) papers suggest a system based on the analysis of hand movement, (3) papers suggest a system based on analysis of eye movement, and (4) papers suggest a system based on analysis of body movement.
Methicillin resistant Staphylococcus aureus (MRSA) isolated from raw milk and nasal swabs of small ruminants in Abeokuta, Nigeria
Venue: Tropical Animal Health and Production
Year: 2020

Methicillin resistant Staphylococcus aureus (MRSA) an important widespread cause of severe infection in both humans and animals, is a significant pathogen of public health concern. This study examined the presence of MRSA in 400 samples comprising 200 raw milks (145 from goat and 55 from sheep) and 200 nasal swabs (145 from goats and 55 from sheep) collected from ten different locations in Abeokuta, Nigeria. Samples were examined using standard bacteriological methods for the isolation and identification of Staphylococcus aureus and culture on oxacillin (6 mg/ml) and cefoxitin (2 mg/ml) selective media for the detection of MRSA. Suspected MRSA isolates were confirmed by latex agglutination test for the detection of penicillin binding protein 2a (PBP2a) Antibiotic susceptibility testing was determined by Kirby Bauer disc diffusion method. Staphylococcus aureus was detected in 72 (18% of 400 samples of which 52 (13% were confirmed as MRSA. Methicillin resistant S. aureus was detected in raw milk (37 of 200; 18.5% and nasal swab (15 of 200; 7.5% There was no significance difference (p 0.05) in the prevalence of MRSA in sheep (37.7% and goat (23.4% The MRSA isolates showed resistance to ampicillin (100% cloxacillin (100% sulphamethoxazole trimethoprim (100% amoxicillin clavulanate (84.6% ceftriaxone (75% cefuroxime (69.2% erythromycin (65.4% streptomycin (38.5% ciprofloxacin (23.1% pefloxacin (21.2% and gentamicin (17.3% The presence of multidrug resistant MRSA in small ruminants reared in Abeokuta metropolis may be due to regular use of antibiotics and unhygienic practices by farmers. This in turn constitutes a potential public health risk to the owners, consumers of small ruminant products and the general populace.
Computational screening of medicinal plant phytochemicals to discover potent pan serotype inhibitors against dengue virus
Venue: Scientific Reports
Year: 2019

Emergence of Dengue as one of the deadliest viral diseases prompts the need for development of effective therapeutic agents. Dengue virus (DV) exists in four different serotypes and infection caused by one serotype predisposes its host to another DV serotype heterotypic re infection. We undertook virtual ligand screening (VLS) to filter compounds against DV that may inhibit inclusively all of its serotypes. Conserved non structural DV protein targets such as NS1, NS3/NS2B and NS5, which play crucial role in viral replication, infection cycle and host interaction, were selected for screening of vital antiviral drug leads. A dataset of plant based natural antiviral derivatives was developed. Molecular docking was performed to estimate the spatial affinity of target compounds for the active sites of DV's NS1, NS3/NS2B and NS5 proteins. The drug likeliness of the screened compounds was followed by ADMET analysis whereas the binding behaviors were further elucidated through molecular dynamics (MD) simulation experiments. VLS screened three potential compounds including Canthin 6 one 9 O beta glucopyranoside, Kushenol W and Kushenol K which exhibited optimal binding with all the three conserved DV proteins. This study brings forth novel scaffolds against DV serotypes to serve as lead molecules for further optimization and drug development against all DV serotypes with equal effect against multiple disease causing DV proteins. We therefore anticipate that the insights given in the current study could be regarded valuable towards exploration and development of a broad spectrum natural anti dengue therapy.
A Technical and Tactical Profile of the Double Olympic Judo Champion: A Case Study
Year: 2014

The technical and tactical analyses of judo competitions are frequently discussed in the literature, yet individual profiling is scarce. The aim of the study was to determine the technical and tactical profile of one of the world's best judokas in the history of judo. Waldemar Legien is a retired Polish judoka and winner of two Olympic gold medals in different weight classes (78 kg and 86 kg) The present research on his career spans the period of 1991 to 1992, during which he competed in 24 tournaments, both at home country and abroad. His outstanding winning record could potentially lie in the fact that he employed techniques from each group of throws. His repertoire of nineteen different techniques, including throws and grapplings, attests to his technical excellence. Our study suggests that one distinctive feature of Legien as a super elite judoka was his technical and tactical versatility.

Effect of Different Green Extraction Methods and Solvents on Bioactive Components of Chamomile (Matricaria chamomilla L. Flowers
Venue: Molecules
Year: 2020

Chamomile (Matricaria chamomilla L. dried flowers contain a group of interesting biologically active compounds such as sesquiterpenes, flavonoids, coumarins, vitamins, phenolic acids and glucosides. Therefore, the aim of the present study was to characterize the composition in bioactive compounds (specialized metabolites) present in water and ethanol extracts of chamomile flowers, together with monitoring the impact of different extraction techniques (conventional vs. ultrasound assisted extraction (UAE) on the parameters under investigation. UAE treatment significantly decreased the extraction time of bioactive compounds from herbal material. Polyphenolic compounds content and antioxidant capacity were significantly higher in UAE extracts. Moreover, solvent type had a significant impact on the specialized metabolites content, while the highest vitamin C and polyphenols content were recorded in 50% ethanol (v/v) extracts. Optimization of basic extraction factors: solvent type, temperature and technique is crucial for obtaining the extracts with the highest content of specialized metabolites and antioxidant capacity.

THE MARKETING CHALLENGES OF SPAZA SHOPS IN DEVELOPING AFRICAN COUNTRIES: THE SOUTH AFRICAN CHALLENGE
Year: 2016

Spaza shop marketing simply means marketing strategies that benefit small businesses. In this time of global recession, small companies are exceptionally proactive in keeping sales up. A number of market related challenges have been identified as contributing to the failure of Spaza shops in South Africa. The research problem of this study emanates from the current high business failure rate. The research investigates whether marketing challenges of Spaza shops contribute to high business failure rate in South Africa. The main hypothesis of the research tried to establish whether there is a positive correlation between lack of marketing skills and business failure of Spaza shops. The conclusion is that a positive correlation exists between marketing skills and business failure in South Africa. In order for the researcher to identify whether all of the marketing challenges contribute to business failure the main hypothesis was divided in five secondary hypotheses. The research has established that there is a significant correlation between the different variables such as competition; low demand of their products; poor locality of their small business; lack of market knowledge; ineffective marketing their products and business failure of Spaza shops. The South African challenge is to improve the marketing skills of small business owners as small business is considered to be the panacea for South Africa's unemployment problems.
Optimal envy free pricing with metric substitutability
Venue: EC '08
Year: 2008

We study the envy free pricing problem faced by a profit maximizing seller when there is metric substitutability among the items consumer i's value for item j is vi ci,j, and the substitution costs, {ci,j} form a metric. Our model is motivated from the observation that sellers often sell the same product at different prices in different locations, and rational consumers optimize the tradeoff between prices and substitution costs. While the general envy free pricing problem is hard to approximate, the addition of metric substitutability constraints allows us to solve the problem exactly in polynomial time by reducing it to an instance of weighted independent set on a perfect graph. When the substitution costs do not form a metric, even in cases when a (1+e) approximate triangle inequality holds, the problem becomes NP hard. Our results show that triangle inequality is the exact sharp threshold for the problem of going from "tractable" to "hard" We then turn our attention to the multi unit demand case, where consumers request multiple copies of the item. This problem has an interesting paradoxical non monotonicity: The optimal revenue the seller can extract can actually decrease when consumers' demands increase. We show that in this case the revenue maximization problem becomes APX hard and give an O(log D) approximation algorithm, where D is the ratio of the largest to smallest demand. We extend these techniques to the more general case of arbitrary non decreasing value functions, and give an O(log3 D) approximation algorithm.
Rate of publication in predatory journals by orthopedic surgeons members of the French orthopedic and traumatology society (SOFCOT) A follow up note.
Venue: Orthopaedics traumatology, surgery research OTSR
Year: 2020

France ranks 9th worldwide for scientific publication in orthopedics and the increase in both the quantity and the quality of its scientific production has been described in detail. On the other hand, publishing by French orthopedic surgeons in predatory journals is more obscure. The journals in question are difficult to identify but are based on an open access model with article processing charges (APC) except in rare cases that are difficult to specify, as they are not stated at the time of submission. The increase in the number of predatory journals over the last 10 years led us to attempt to assess the rate at which French orthopedic surgeons publish in them, as revealed by investigation of the SIGAPS bibliometric database.  Over the period 2008 2017, the rate of publications by French orthopedic surgeons in predatory journals was less than 5% MATERIAL AND METHOD The SIGAPS database contains the detail of publications by French orthopedic surgeons members of the French Society of Orthopedic Surgery and Traumatology (SoFCOT) and was used to analyse all such articles (journal article, review or editorial) so as to isolate articles with PubMed Not MEDLINE status falling in the SIGAPS non classified (NC) category and to determine the predatory status of the journal using established lists, such as Beall's list or that drawn up by StopPredatoryJournals. In case of difficulty in determining predatory status, we applied the criteria defined by Beall and the Committee on Publication Ethics (COPE) RESULTS Out of 6056 articles in the SIGAPS database published by French orthopedic surgeons between 2008 and 2017, 323 could be suspected of being published in a predatory journal, but only 33 were so confirmed: i.e. 0.55% of French orthopedic scientific output over the study period. Eleven appeared in journals whose publishers were listed as predatory by Beall, 21 appeared in journals whose publishers had been listed as predatory on Beall's list in 2012 with the dubious editorial practices defined by Beall, and one article appeared in a journal found to be predatory on analysis of its editorial board. More than half of these articles (58% were subject to APCs averaging $400.  Despite a strong increase in the number of predatory journals over the last decade, very few French orthopedic surgeons resort to them to publish their work. Difficulty of identification and authors' lack of knowledge about this type of journals may account for some of these submissions. Scientific teams need to check certain criteria before submitting to a journal: short time to publication and low APC should be taken as warning signs, and any demand for payment after acceptance certainly raises the question of the journal's predatory nature.
Towards a holistic approach for multi objective optimization of food processes: A critical review
Venue: Trends in Food Science Technology
Year: 2019

While Multi objective Optimization (MOO) has provided many methods and tools for solving design problems, food processes have benefitted little from them. MOO encompasses the identification of performance indicators, process modelling, preference integration, trade off assessment, and finding the best trade offs. In this review, the use of these five elements in the design of food processes through MOO is analysed. A number of studies dealing with food processes MOO have been identified. Even though these studies improve the design process, they often approach MOO in a simplified and insufficiently rationalized way. Based on this review, several research issues are identified, related to the improvement of the different models and methods, and to the development of more holistic MOO methods for food processes.  The challenge of food process engineering, taking into account the many constraints, is becoming increasingly difficult. Multi objective Optimization (MOO) has provided many methods and tools to solve design problems, which often entail conflicting objectives (e.g. product quality vs. profit) Thus, only a trade off can result from the design process, where preferences and weighting of the conflicting objectives has to be included. Scope and approach In this review, MOO methods used in food process design studies are analysed through the framework of the five elements which constitute a MOO method: i) performance indicators to quantify the design objectives; ii) a predictive process model to evaluate the different design solutions; iii) decision maker and/or expert preferences, expressed as weights of the different objectives and satisfaction levels on indicator values; iv) a selection method to select one or several "best" trade offs; v) an optimization algorithm to find the best design solutions among the feasible ones.  The authors highlight the fact that more holistic MOO methods can be used to improve the design process, as numerous methods have been developed to build MOO methods, particularly in the field of Multi criteria Decision Making (MCDM) The literature reveals that MOO is often approached in a simplified and insufficiently rationalized way, which hinders the use of MCDM methods to improve the design process. Several research issues are also identified, related to the improvement of the different models and methods, which could help develop more holistic MOO methods for food processes.

In this paper, different chiral tartaric acid molecules were immobilized on the surface of Ti O films. XPS test results showed the peak of nitrogen appeared on the samples which had deposited dopamine, the ratio of nitrogen to carbon was increased when hexamethylendiamine was introduced. When chiral tartaric acid was grafted, the ratio of oxygen to carbon was increased. XPS results showed that all surfaces had been successfully prepared. The water contact angle test results showed that no difference was present on the L surface and D surface, indicating that surface chirality had little effect on surface hydrophobicity. The effects of chirality on the blood compatibility of materials were evaluated by fibrinogen denaturation test and platelet adhesion and activation assay in vitro. Compared with L tartaric acid surface, D tartaric acid surface showed a lower degree of denatura tion of fibrinogen, less platelet adhesion and a lower degree of platelet activation. These results indicate that chirality cannot be ignored in the anticoagulant properties of biomaterials, which provides a new idea for the development of anticoagulant materials with excellent properties.
Continuous software engineering: A roadmap and agenda
Venue: J. Syst. Softw.
Year: 2017

Throughout its short history, software development has been characterized by harmful disconnects between important activities such as planning, development and implementation. The problem is further exacerbated by the episodic and infrequent performance of activities such as planning, testing, integration and releases. Several emerging phenomena reflect attempts to address these problems. For example, Continuous Integration is a practice which has emerged to eliminate discontinuities between development and deployment. In a similar vein, the recent emphasis on DevOps recognizes that the integration between software development and its operational deployment needs to be a continuous one. We argue a similar continuity is required between business strategy and development, BizDev being the term we coin for this. These disconnects are even more problematic given the need for reliability and resilience in the complex and data intensive systems being developed today. We identify a number of continuous activities which together we label as 'Continuous (i.e. Continuous Star which we present as part of an overall roadmap for Continuous Software engineering. We argue for a continuous (but not necessarily rapid) software engineering delivery pipeline. We conclude the paper with a research agenda.
A Neural Network Approach to Context Sensitive Generation of Conversational Responses
Venue: NAACL
Year: 2015

We present a novel response generation system that can be trained end to end on large quantities of unstructured Twitter conversations. A neural network architecture is used to address sparsity issues that arise when integrating contextual information into classic statistical models, allowing the system to take into account previous dialog utterances. Our dynamic context generative models show consistent gains over both context sensitive and non context sensitive Machine Translation and Information Retrieval baselines.
Transcriptome analysis of gravitational effects on mouse skeletal muscles under microgravity and artificial 1 g onboard environment
Venue: Scientific reports
Year: 2021

Spaceflight causes a decrease in skeletal muscle mass and strength. We set two murine experimental groups in orbit for 35 days aboard the International Space Station, under artificial earth gravity (artificial 1 g; AG) and microgravity (mg; MG) to investigate whether artificial 1 g exposure prevents muscle atrophy at the molecular level. Our main findings indicated that AG onboard environment prevented changes under microgravity in soleus muscle not only in muscle mass and fiber type composition but also in the alteration of gene expression profiles. In particular, transcriptome analysis suggested that AG condition could prevent the alterations of some atrophy related genes. We further screened novel candidate genes to reveal the muscle atrophy mechanism from these gene expression profiles. We suggest the potential role of Cacng1 in the atrophy of myotubes using in vitro and in vivo gene transductions. This critical project may accelerate the elucidation of muscle atrophy mechanisms.
