The paper presents an efficient algorithm to detect small infrared target based on the principle of background prediction and image blocking according to the feature of small IR target in a complex background.Using the edge detection,maximum mean algorithm and partial similar methods,this approach can obtains a more accurate background.With the adoption of the statistical segmentation method,the proposed method can obtain a more accurate position of target from the residual images.In the process,the image block technique is used to improve the efficiency of the algorithm.Finally,three typical series of IR video were selected to verify the performance of the algorithm.The computer simulations show that the presented algorithm has more advantages in the detection accuracy,robustness,and calculation efficiency.
Reinforcement Learning in Neural Networks: A Survey
Year: 2014

In recent years, researches on reinforcement learning (RL) have focused on bridging the gap between adaptive optimal control and bio inspired learning techniques. Neural network reinforcement learning (NNRL) is among the most popular algorithms in the RL framework. The advantage of using neural networks enables the RL to search for optimal policies more efficiently in several real life applications. Although many surveys investigated general RL, no survey is specifically dedicated to the combination of artificial neural networks and RL. This paper therefore describes the state of the art of NNRL algorithms, with a focus on robotics applications. In this paper, a comprehensive survey is started with a discussion on the concepts of RL. Then, a review of several different NNRL algorithms is presented. Afterwards, the performances of different NNRL algorithms are evaluated and compared in learning prediction and learning control tasks from an empirical aspect and the paper concludes with a discussion on open issues.
Multi Stimuli Nanocomposite Therapeutic: Docetaxel Targeted Delivery and Synergies in Treatment of Human Breast Cancer Tumor.
Venue: Small
Year: 2020

A versatile breast cancer targeting nanocomposite therapeutic combining docetaxel (DXL) polyvinyl alcohol (PVA) network for controlled release, and silica protected magnetic iron oxide nanoparticles (Fe3 O4 NPs) for targeted delivery and gold nanoparticles (AuNPs) for plasmonic photothermal therapy (PPTT) is presented in this work. First, the designed nanocomposite is magnetically directed for cancer targeted therapy confirmed by computerized tomography (CT) scans. Second, 10% DXL by mass is loaded into PVA, a pH and temperature responsive gel, for controlled release. Third, PPTT is confirmed with Au/Fe3 O4 /PVA 10%DXL using a prototype circulation system and then for tumor treatment in vivo; Au/Fe3 O4 /PVA 10%DXL is conveniently directed and the entrapped DXL is selectively released (96% via the interaction of green and near infrared (NIR) light with the localized surface plasmon resonance of AuNPs. A 75% cell death is reported from in vitro studies with DXL doses as low as 20 ug mL 1 of Au/Fe3 O4 /PVA 10%DXL, and a 70% tumor growth inhibition is demonstrated by in vivo experiments with the biosafety studies confirming minimal side effects to other organs. Overall, the developed Au/Fe3 O4 /PVA 10%DXL has a strong potential to simultaneously enhance CT imaging contrast together with the targeted delivery of DXL.
Multi Label Automatic Labeling for Question Attributes Based on Adaboost and Bayes Algorithms
Venue: 2018 Chinese Automation Congress (CAC)
Year: 2018

The attributes, such as knowledge points and difficulty, are important parts of questions. It is related to the automatic classification, auto generating test paper and adaptive learning. The traditional labeling, however, is done by domain experts and teachers with low efficiency which make it difficult to achieve large scale automatic labeling. Automatic labeling not only saves a lot of manual labeling costs, but also executes question labeling in batches. Question labeling is an essential text multi label classification problem. In this paper, we propose an improved multi label classification algorithm based on naive Bayes algorithm, combined with AdaBoost algorithm. We develop a new evaluation model of classification precision for the hierarchical characteristic of question knowledge point structure. The experimental results demonstrate the proposed algorithm outperforms to the naive Bayes algorithm and the SVM algorithm in precision, recall and Fl value.
The Campo Laborde site: New evidence for the Holocene survival of Pleistocene megafauna in the Argentine Pampas
Year: 2008

Investigations have been carried out at the Campo Laborde archaeological site in the Argentine Pampas. Some issues related to Pleistocene extinctions and the survivals of some species of megafauna into the Early Holocene are discussed. At the site of Campo Laborde, abundant bones of giant ground sloth Megatherium americanum some from other Pleistocene fauna Doedicurus sp. and Neosclerocaliyptus sp. and very few from extant fauna (e.g. vizcacha Lagostomus maximus Patagonian hare Dolichotis patagonum and peccary Tayassu sp. were found in association with two quartzite tools, 128 microlithic debris from different raw material and two informal bone tools. Each of the species is represented by only one individual and only one bone of M. americanum and one of D. patagonum show cut marks. Different lines of evidence suggest that Campo Laborde is a giant ground sloth procurement site on the border of an ancient swamp, where the prey was also initially butchered. One of the recovered tools is the stem of a broken bifacial projectile point, which would have been used as a hunting weapon. Based on the stratigraphic position, this site could date to the Early Holocene. Six AMS 14 C ages from M. americanum bone collagen, support this age although there is a wide chronological span between ca. 9700 and 6700 BP. The evidence obtained from Campo Laborde as well as from the La Moderna site indicates that some Pleistocene species such as giant ground sloth and some glyptodon D. clavicaudatus and Neosclerocaliyptus sp. survived in the Pampas until the Early Holocene. Therefore, these megafauna coexisted with early hunter gatherers for several millennia and were exploited.
The brain disease model of addiction: is it supported by the evidence and has it delivered on its promises?
Venue: The lancet. Psychiatry
Year: 2015

Since 1997 the US National Institute on Drug Abuse has advocated a brain disease model of addiction (BDMA) We assess the strength of evidence for the BDMA in animals, neuroimaging studies of people with addiction, and current research on the role of genetics in addiction. We critically assess claims about the medical and social benefits of use of the BDMA because the social implications are often implied as a reason to accept this model. Furthermore, we argue that the BDMA is not supported by animal and neuroimaging evidence to the extent its advocates suggest; it has not helped to deliver more effective treatments for addiction; and its effect on public policies toward drugs and people with addiction has been modest. The focus of the BDMA is on disordered neurobiology in a minority of severely addicted individuals, which undermines the implementation of effective and cost effective policies at the population level to discourage people from smoking tobacco and drinking heavily. The pursuit of high technology direct brain interventions to cure addiction when most individuals with addiction do not have access to effective psychosocial and drug treatments is questionable.
Optimization of the Post Logistics Network and Location of the Local Distribution Center in Selected Area of the Lublin Province
Year: 2017

These days customers expect the lowest price of postal services but still they look forward to its' wide availability, security and delivery of mail items on time. The most important in generating the total costs in these services is transport cost of postal items. Transport costs depend on many factors purchase price of the vehicle, labor costs of the drivers, costs of maintenance and repairs, fuel costs etc. Hence, it is so important to find organizational solutions that can reduce the costs associated with the transportation of postal shipments, thereby reducing the total cost of postal services. An excellent way for doing it is to minimize the length of postal transportation routes, what means finding the shortest ways between post offices in selected area. This article presents the results of analysis and researches on existing postal network, which were based on the graph theory, in order to optimize actual network. Realized computer simulations were oriented to find a new location of the local distribution center. The relocation of local distribution center leads to minimize of the transport costs for delivery postal items "from point to point" of Polish Post SA network in the selected area of the Lublin province.

Integrating solid state sensor and microfluidic devices for glucose, urea and creatinine detection based on enzyme carrying alginate microbeads.
Venue: Biosensors bioelectronics
Year: 2013

A solid state sensor embedded microfluidic chip is demonstrated for the detection of glucose, urea and creatinine in human serum. In the presented device, magnetic powder containing enzyme carrying alginate microbeads are immobilized on the surface of an electrolyte insulator semiconductor (EIS) sensor by means of a step like obstacle in the microchannel and an external magnetic force. The sample is injected into the microchannel and reacts with the enzyme contained within the alginate beads; prompting the release of hydrogen ions. The sample concentration is then evaluated by measuring the resulting change in the voltage signal of the EIS sensor. The reaction time and alginate bead size are optimized experimentally using a standard glucose solution. The experimental results show that the device has a detection range of 2 8mM, 1 16mM and 10( 2) 10mM for glucose, urea and creatinine, respectively. Furthermore, it is shown that the device is capable of sequentially measuring all three indicators in a human serum sample. Finally, it is shown that the measured values of the glucose, urea and creatinine concentrations obtained using the device deviate from those obtained using a commercial kit by just 5.17% 6.22% and 13.53% respectively. This method can be extended to sequentially measure multiple blood indicators in the sample chip by replacing different types of enzyme in alginate bead and can address the enzyme preservation issue in the microfluidic device. Overall, the results presented in this study indicate that the microfluidic chip has significant potential for blood monitoring in point of care applications.
Super Resolution of the Magnetic Resonance Imaging Reconstruction

Working towards least restrictive environments in acute mental health wards in the context of locked door policy and practice
Venue: International journal of mental health nursing
Year: 2019

There has been a shift towards provision of mental health care in community based settings in Australia. However, hospitals continue to care for people in acute mental health wards. An increasing proportion of the people in wards are admitted involuntarily, subject to restrictions of movement to minimize risk of harm to self and others. In response to concerns about the safety of people absconding from care, Queensland Health introduced a policy requiring all acute mental health wards in the State to be locked. In response, the Queensland Mental Health Commission funded a project to understand the impact of this policy and develop evidence based recommendations regarding provision of least restrictive, recovery oriented practices in acute wards. Facilitated forums were conducted with 35 purposively selected participants who identified as consumers, carers, or staff of acute mental health hospital wards, to test the acceptability, feasibility, and face validity of a set of evidence informed recommendations for providing least restrictive, recovery oriented practices. Participant responses were recorded, and data were analysed through an inductive, thematic approach. A recovery oriented approach was supported by all stakeholders. Reducing boredom and increasing availability of peer support workers were considered key to achieving this. Focusing less on risk aversion was reported as central to enabling true Recovery Orientation. This project enabled recognition of the perspectives of consumers, carers, and staff in the consideration of evidence informed recommendations that could be implemented to provide least restrictive care in the context of locked doors.
Reasons for the changes of the concepts of human nature in the economics exemplified on the contemporary trends[1]
Year: 2015

The main objective of this paper is to characterize the key trends responsible for the changes of the concepts of human nature in the economics. The methodology is both deductive (conclusions from theories developed within social sciences and humanities) and inductive (observation of current trends, which according to the theory are potentially responsible for those changes) Basing on the insights of psychology, philosophy of science, sociology, and cognitive science main potential forces are deduced. From the observation of actual trends, the basic contemporary factors responsible for the changes of the concepts of human nature are distinguished. Those can be divided in three groups. The first group contains factors focusing on the advance in knowledge about the human being, occurring within the general and specific sciences dealing with man (e.g. psychology, sociology, philosophy, cognitive science) The second group of factors includes the increasing complexity of the social processes. The third group refers to those social trends, which are responsible for altering understanding the world, which in turn results in real changes. Virtualization of life, greater sensitivity to human and environmental issues, increased contacts with other cultures and religions, greater sensitivity to the existing social injustice are some of those factors. Basing on those results, the reasons for growing criticism of traditional, orthodox image of man in the economics are discussed and the postulates of the heterodox economics for modifications in the concept of human nature, which reflect the changes taking place in society.

A new species Melanostigma thalassium sp. n. is described from the underwater Walvis Ridge (Southeast Atlantic Ocean) This species differs from the other species of the genus Melanostigma in an original combination of characters based on the structure of the head's lateral line system (interruption in supratemporal commissure with the loss of medial segments and the absence of pores in the temporal canal) and a nontransparent dark body. In addition, it is different in a range of the count characters in the axial skeleton and fins. A key for identifying the Atlantic species of the genus is provided.
Aging causes a reorganization of cortical and spinal control of posture
Venue: Front. Aging Neurosci.
Year: 2014

Classical studies in animal preparations suggest a strong role for spinal control of posture. In humans it is now established that the cerebral cortex contributes to postural control of unperturbed and perturbed standing. The age related degeneration and accompanying functional changes in the brain, reported so far mainly in conjunction with simple manual motor tasks, may also affect the mechanisms that control complex motor tasks involving posture. This review outlines the age related structural and functional changes at spinal and cortical levels and provides a mechanistic analysis of how such changes may be linked to the behaviorally manifest postural deficits in old adults. The emerging picture is that the age related reorganization in motor control during voluntary tasks, characterized by differential modulation of spinal reflexes, greater cortical activation and cortical disinhibition, is also present during postural tasks. We discuss the possibility that this reorganization underlies the increased coactivation and dual task interference reported in elderly. Finally, we propose a model for future studies to unravel the structure function behavior relations in postural control and aging.

Temporal considerations in the 2021 COVID 19 lockdown of Ho Chi Minh City
Venue: medRxiv
Year: 2021

The success of Vietnam in controlling the spread of COVID 19 hinges on a timely implementation of its coherent strategy of containment and rapid tracing and testing efforts. The Vietnamese living in Mekong Delta are currently being besieged by the SARS Cov 2 Delta variant as they undergo several and extended levels of lockdown. In this work we examine the temporal aspects of the lockdown in Ho Chi Minh City and predict the progress of the outbreak in terms of the total number of confirmed cases. A compartmental model with containment is fit to data to estimate the rate of transmission in Ho Chi Minh City. The severity of the lockdown is estimated from publicly available data on mobility and coupled to the rate of infection. Various scenarios on when to begin a lockdown and its duration are assessed. This report, dated 27 July 2021, supports a lockdown of at least 3 weeks and predicts that there could be half as many cases had the inevitable lockdown started a week earlier.

Venue: The Australian journal of advanced nursing a quarterly publication of the Royal Australian Nursing Federation
Year: 2006

The critical role of research in nursing practice is the application of nursing theories to discover new knowledge. This study uses King's interacting systems framework and theory of goal attainment to investigate the effectiveness of implementing clinical pathways for patients undergoing transurethral resection of prostate (TURP) at Aga Khan University Hospital (AKUH) Pakistan.  To assess the impact of the implementation of a clinical pathway for the surgical procedure of TURP on clinical quality, cost, and patient and staff satisfaction.  Quasi experimental, non equivalent control group study design using clinical pathway intervention.  Aga Khan University Hospital (AKUH) SUBJECTS The study population consisted of a convenience sample of patients undergoing surgery for TURP (control and experimental) and health team members (nurses, physicians and others)  Findings showed a significant difference in variances and outcomes as a result of TURP clinical pathway intervention. The clinical pathway significantly improved all twelve nursing and physician related variances and outcomes, such as: complete documentation; delayed consultation; delayed education; and other variances. Clinical pathway intervention also significantly reduced hospital related variances, and post operative problems such as electrolyte imbalance, phlebitis, constipation, and urinary tract infection (UTI) The findings also showed significant improvement in patient and staff satisfaction, however no significant difference was observed in patient, hospital and financial related variances. The current investigation identified that successful implementation of integrated clinical pathways can help health professionals, managers and administrators to meet one of their biggest challenges in making optimal use of limited resources while delivering high quality and timely care.
Improving the efficiency of pumping equipment at the gold mining companies of the Far North
Venue: IOP Conference Series: Earth and Environmental Science
Year: 2021

Practice shows that in the conditions of gold mining enterprises in Yakutia, the MTBF of double acting pumps is relatively small and can be no more than 100 motor hours. Emergency downtime caused by the repair of pumping equipment is highly undesirable, since they negatively affect the safety of mining operations, as well as the technical and economic performance of the gold mining enterprise. The purpose of this research work is to establish the reasons for the low operational reliability of double acting pumps during open development of gold bearing deposits in Yakutia, as well as to establish the most optimal technical solution to improve the efficiency of pumping equipment under specified operating conditions.
