V Visual Tracking Under Motion Blur

Most existing tracking algorithms do not explicitly consider the motion blur contained in video sequences, which degrades their performance in real-world applications where motion blur often occurs. In this paper, we propose to solve the motion blur problem in visual tracking in a unified framework. Specifically, a joint blur state estimation and multi-task reverse sparse learning framework are presented, where the closed-form solution of blur kernel and sparse code matrix is obtained simultaneously. The reverse process considers the blurry candidates as dictionary elements, and sparsely represents blurred templates with the candidates. By utilizing the information contained in the sparse code matrix, an efficient likelihood model is further developed, which quickly excludes irrelevant candidates and narrows the particle scale down. Experimental results on the challenging benchmarks show that our method performs well against the state-of-the-art trackers.
Genetics of Degenerative Cervical Myelopathy: A Systematic Review and Meta-Analysis of Candidate Gene Studies

Degenerative cervical myelopathy (DCM) is estimated to be the most common cause of adult spinal cord impairment. Evidence that is suggestive of a genetic basis to DCM has been increasing over the last decade. A systematic search was conducted in MEDLINE, EMBASE, Cochrane, and HuGENet databases from their origin up to 14th December 2019 to evaluate the role of single genes in DCM in its onset, clinical phenotype, and response to surgical intervention. The initial search yielded 914 articles, with 39 articles being identified as eligible after screening. We distinguish between those contributing to spinal column deterioration and those contributing to spinal cord deterioration in assessing the evidence of genetic contributions to DCM. Evidence regarding a total of 28 candidate genes was identified. Of these, 22 were found to have an effect on the radiological onset of spinal column disease, while 12 genes had an effect on clinical onset of spinal cord disease. Polymorphisms of eight genes were found to have an effect on the radiological severity of DCM, while three genes had an effect on clinical severity. Polymorphisms of six genes were found to have an effect on clinical response to surgery in spinal cord disease. There are clear genetic effects on the development of spinal pathology, the central nervous system (CNS) response to bony pathology, the severity of both bony and cord pathology, and the subsequent response to surgical intervention. Work to disentangle the mechanisms by which the genes that are reviewed here exert their effects, as well as improved quality of evidence across diverse populations is required for further investigating the genetic contribution to DCM.
The effect of entrustable professional activities on pathology resident confidence in blood banking/transfusion medicine

The Accreditation Council for Graduate Medical Education requires milestone reporting of the Six General Core Competencies. Additionally, Graduate Medical Education (GME) is transitioning to adopt competency‐based education methodologies including entrustable professional activities (EPAs) for objective, observable, and measurable milestone progression. The College of American Pathologists published 19 EPAs, including one for transfusion‐related adverse events. This survey study includes developing EPAs for transfusion reaction evaluation and assessing residents before and after implementing these EPAs.
Innovation and Revenue: Deep Diving into the Temporal Rank-shifts of Fortune 500 Companies

Research and innovation is an important agenda for any company to remain competitive in the market. The relationship between innovation and revenue is a key metric for companies to decide on the amount to be invested for future research. Two important parameters to evaluate innovation are the quantity and quality of scientific papers and patents. Our work studies the relationship between innovation and patenting activities for several Fortune 500 companies over a period of time. We perform a comprehensive study of the patent citation dataset available in the Reed Technology Index collected from the US Patent Office. We observe several interesting relations between parameters like the number of (i) patent applications, (ii) patent grants, (iii) patent citations and Fortune 500 ranks of companies. We also study the trends of these parameters varying over the years and derive causal explanations for these with qualitative and intuitive reasoning. To facilitate reproducible research, we make all the processed patent dataset publicly available.1
Enabling Real-Time Feedback in Software Engineering

Modern software projects consist of more than just code: teams follow development processes, the code runs on servers or mobile phones and produces run time logs and users talk about the software in forums like StackOverflow and Twitter and rate it on app stores. Insights stemming from the real-time analysis of combined software engineering data can help software practitioners to conduct faster decision-making. With the development of CodeFeedr, a Real-time Software Analytics Platform, we aim to make software analytics a core feedback loop for software engineering projects. CodeFeedr's vision entails: (1) The ability to unify archival and current software analytics data under a single query language, and (2) The feasibility to apply new techniques and methods for high-level aggregation and summarization of near real-time information on software development. In this paper, we outline three use cases where our platform is expected to have a significant impact on the quality and speed of decision making; dependency management, productivity analytics, and run-time error feedback.
Between designer drugs and afterburners : A Lexicographic-Semantic Study of Equivalence

The lexicons of natural languages are not isomorphic. Reasons for the anisomorphism can be sought on three interrelated planes: language structure, extralinguistic reality, and conceptualisation. Simply put, the relevant differences may reside in the language, the world, the mind, or any combination of these. As a result, what goes under the name of lexicographic equivalence is a rather heterogeneous category. Growing awareness of this fact has resulted over the years in the creation of several tentative typologies of equivalence, one of which is presented below, together with a brief discussion of some strategies for dealing with imperfect equivalence. The remaining part of the article comprises a detailed analysis of a single problem encountered while preparing a new edition of a bilingual dictionary for Polish learners of English. The task at hand involved choosing a viable counterpart for a (Polish) semantic neologism from among a few (English) equivalence candidates. In the discussion, reference is made both to the metalexicographic categories introduced earlier and to such concepts developed by lexical (especially cognitive) semantics which may prove helpful in capturing the meaning differences between the sourcelanguage item and its competing target-language renditions. This micro-scale dissection of a single specimen demonstrates that we are still some way from being able to classify, let alone deal with, all the instances of imperfect interlingual correspondence that come our way. Persisting in the efforts to advance our understanding of the complex issues covered by the blanket term lexicographic equivalence thus seems crucial for improving the treatment of meaning in bilingual dictionaries.
Typology and Unified Model of the Sharing Economy in Open Innovation Dynamics

The sharing economy is emerging as one of the hottest issues of the Fourth Industrial Revolution. The ownership paradigm was dominant during the First and Second Industrial Revolutions, so the formation of the sharing economy was almost non-existent, but it has grown to 5% of the global GDP during the Third Industrial Revolution as the sharing paradigm became prominent. It is expected that the scale of the sharing economy will reach up to 50% of the global economy by 2025 as the online to offline convergence (O2O) phenomenon (GE, 2012). The sharing economy is generally considered complex, diverse, and simply chaotic territory due to its various meanings or types despite its importance. In short, there is a great need to do more research to develop a unified model of the sharing economy. Our study defines sharing economy as “an activity where economic agents share economic objects together to create values”. The KCERN Sharing Economy Cube Model presented in the study is a unified model where the subjects of sharing—supply, market platform, demand, etc.—share the objects of sharing—information, materials, relations, etc.—in order to engage in economic activities, both for profit and nonprofit, to create values. The model reflects all these activities and encompasses all the other definitions of the sharing economy. This study aims to systematically draw a roadmap for the national sharing economy in the ongoing Fourth Industrial Revolution era based on the integrative sharing platform economy model.
Disparate Effects Renal of Calcium Antagonists Microcirculation

preglomerular and postglomerular microcirculation have been suggested to differ. In the present study we examined the vasodilator action of dihydropyridine-type calcium antagonists, including nifedipine, nicardipine, amlodipine, and efonidipine, on afferent and efferent arterioles during angiotensin II (A-II)and norepinephrine (NE)-induced renal vasoconstriction. Isolated perfused hydronephrotic kidneys were used to directly visualize renal microcirculatory response to calcium antagonists. Both A-II and NE caused marked vasoconstriction of afferent (A-II, 27 ± 2 % decrement; NE, 28 ± 2 % decrement) and efferent arterioles (A-II, 25 ± 4 % decrement; NE, 22 ± 2 % decrement). The subsequent addition of nifedipine, nicardipine, and amlodipine reversed the afferent arteriolar vasoconstriction in a dose-dependent manner, and elicited complete vasodilation at 10-6 M. In contrast, efferent arteriolar vasoconstriction was relatively refractory to the dilator action of these calcium antagonists; maximal dilation observed at 106 M was 21 ± 1 % (A-II) and 22 ± 3 % (NE) for nifedipine, 25 ± 3 % (A-II) and 20 ± 6 % (NE) for nicardipine, and 39 ± 6 % (A-II) and 37 ± 3 % (NE) for amlodipine. In striking contrast, efonidipine dilated not only afferent arterioles, but also efferent arterioles in a dose-dependent manner. At 10-6 M, efonidipine completely inhibited the afferent (A-II, 89 ± 7 % reversal; NE, 99 ± 8 % reversal) and efferent arteriolar vasoconstriction (A-II, 93 ± 4 % reversal; NE, 87 ± 9 % reversal). These findings clearly demonstrate that calcium antagonists dilate the afferent arteriole. Unlike the effects on the afferent arteriole, efferent arteriolar responsiveness to calcium antagonists differ, depending on the type of calcium antagonist. The efonidipine-induced efferent arteriolar vasodilation is probably not related to voltageoperated calcium channels, and may act, in concert with blood pressure lowering effect, to ameliorate glomerular capillary hypertension.

Identification of AIDS-Associated Kaposi Sarcoma: A Functional Genomics Approach

Background Kaposi sarcoma-associated herpes virus (KSHV) is one of the most common causal agents of Kaposi Sarcoma (KS) in individuals with HIV-infections. The virus has gained attention over the past few decades due to its remarkable pathogenic mechanisms. A group of genes, ORF71, ORF72, and ORF73, are expressed as polycistronic mRNAs and the functions of ORF71 and ORF72 in KSHV are already reported in the literature. However, the function of ORF73 has remained a mystery. The aim of this study is to conduct comprehensive exploratory experiments to clarify the role of ORF73 in KSHV pathology and discover markers of AIDS-associated KSHV-induced KS by bioinformatic approaches. Methods and Results We searched for homologues of ORF-73 and attempted to predict protein-protein interactions (PPI) based on GeneCards and UniProtKB, utilizing Position-Specific Iterated BLAST (PSI-BLAST). We applied Gene Ontology (GO) and KEGG pathway analyses to identify highly conserved regions between ORF-73 and p53to help us identify potential markers with predominant hits and interactions in the KEGG pathway associated with host apoptosis and cell arrest. The protein p53 is selected because it is an important tumor suppressor antigen. To identify the potential roles of the candidate markers at the molecular level, we used PSIPRED keeping the conserved domains as the major parameters to predict secondary structures. We based the FUGE interpretation consolidations of the sequence-structure comparisons on distance homology, where the score for the amino acids matching the insertion/deletion (indels) detected were based on structures compared to the FUGE database of structural profiles. We also calculated the compatibility scores of sequence alignments accordingly. Based on the PSI-BLAST homologues, we checked the disordered structures predicted using PSI-Pred and DISO-Pred for developing a hidden Markov model (HMM). We further applied these HMMs models based on the alignment of constructed 3D models between the known structure and the HMM of our sequence. Moreover, stable homology and structurally conserved domains confirmed that ORF-73 maybe an important prognostic marker for AIDS-associated KS. Conclusion Collectively, similar variants of ORF-73 markers involved in the immune response may interact with targeted host proteins as predicted by our computational analysis. This work also suggests the existence of potential conformational changes that need to be further explored to help elucidate the role of immune signaling during KS towards the development of therapeutic applications.
Childhood overweight and obesity conceived by Child Health Care nurses : a qualitative study

Background: Registered Sick Children’s Nurses and District Nurses employed at Child Health Care centres are in a position to help prevent childhood overweight and obesity. Prevention of this challenging public health threat could be improved through having a better understanding of how this group of nurses perceives childhood obesity. The aim of this study was to elucidate the conceptions of childhood overweight, including obesity, among nurses working in Child Health Care. Method: A qualitative study using a phenomenographic approach, based on open-ended interviews with 18 Child Health Care nurses (CHC-nurses) strategically selected from 17 Child Health Care Centres in the southern part of Sweden. Results: Four categories of description emerged from the data: Perception of childhood overweight changes, Overweight in younger children a neglected concern, Overweight a delicate issue and Importance of family lifestyle. The participating CHC-nurses conceived overweight in children, primarily obesity in children to be an extensive and serious problem which affects children, families and the surrounding society. Overweight in children was further perceived as a consequence of their parent’s lifestyle and their awareness of the problem, which was considered by the CHC-nurses as a sensitive and a provoking issue. It was also perceived that overweight in children is not taken seriously during the pre-school period and that concerns regarding overweight in younger children were mainly about the appearance and not the health of the child. The CHC-nurses perceived that the proportion of overweight children has increased, which Swedish society and the CHC-nurses have adapted to. This adaptation makes it difficult for CHC-nurses to define those children who are overweight. Conclusion: CHC-nurses provide a comprehensive and complex picture of childhood overweight, which includes several difficulties dealing with this issue. Attention to CHC-nurse’s conceptions of overweight in children is important since it can affect the parent-nurse relationship and thereby the nurse’s, as well as the parent’s efforts to influence the children’s weight. It is suggested that CHCnurses should work with person centered counseling and empowerment concerning parent to child relations in cases involving overweight.
Dual-/Tri-Wideband Bandpass Filter with High Selectivity and Adjustable Passband for 5G Mid-Band Mobile Communications

The design and implementation of the filters for the fifth-generation (5G) mobile communication systems are challengeable due to the demands of high integration, low-cost, and high-speed data transmission. In this paper, a dual-wideband bandpass filter (BPF) and a tri-wideband BPF for 5G mobile communications are proposed. The dual-wideband BPF consists of two folded open-loop stepped-impedance resonators (FOLSIRs), and the tri-wideband BPF is designed by placing a pair of folded uniform impedance resonator inside the dual-wideband BPF with little increase in the physical size of the filter. By employing a novel structural deformation of a stepped-impedance resonator, the FOLSIR is achieved with a more compact structure, a controllable transmission zero, and an adjustable resonant frequency. The measurement results show that the working bands of the two filters are 1.98–2.28/3.27–3.66 GHz and 2.035–2.305/3.31–3.71/4.54–5.18 GHz, respectively, which are consistent with the full-wave EM simulation results. The implemented filters have a compact size and the results show low loss, good out-of-band rejection, and wide passbands covering sub-6 GHz bands of 5G mobile communications and a commonly used spectrum.
Valorization of Lignin as a Sustainable Component of Structural Materials and Composites: Advances from 2011 to 2019

Lignin is the most abundant aromatic biopolymer and is the sustainable feedstock most likely to supplant petroleum-derived aromatics and downstream products. Rich in functional groups, lignin is largely peerless in its potential for chemical modification towards attaining target properties. Lignin’s crosslinked network structure can be exploited in composites to endow them with remarkable strength, as exemplified in timber and other structural elements of plants. Yet lignin may also be depolymerized, modified, or blended with other polymers. This review focuses on substituting petrochemicals with lignin derivatives, with a particular focus on applications more significant in terms of potential commercialization volume, including polyurethane, phenol-formaldehyde resins, lignin-based carbon fibers, and emergent melt-processable waste-derived materials. This review will illuminate advances from the last eight years in the prospective utilization of such lignin-derived products in a range of application such as adhesives, plastics, automotive components, construction materials, and composites. Particular technical issues associated with lignin processing and emerging alternatives for future developments are discussed.
The influence of educational attainment and immigration status on outcomes of a national self-management program for hip and knee osteoarthritis – results on 22 741 patients from the BOA register

Background: Supervised exercise and delivered education are first step treatment for knee, hip and hand osteoarthritis (OA) according to international guidelines. It is uncertain whether OA outcomes from participation in the Swedish self-management program ―Better management of Osteoarthritis (BOA)‖ differs for participants with different sociodemographic background. The aim of this master thesis was thus to assess to what extent there were differences by level of education and immigration status among participants in the self-management program in terms of Health, Health-related quality of life, Mobility, Health-related behaviours and Adherence to the self-management program, measured at baseline, three and 12 months. Methods: Analysis of covariance (ANCOVA), logistic and multinomial regression was used to analyse outcomes for 22 741 participants. Results: For most adjusted outcomes, there were sociodemographic inequalities at all measurement points. However, there were no educational differences in mobility and attitude to physical activity at baseline, but at the follow-ups such inequalities emerged. Conversely, the willingness to undergo joint surgery differed by immigration status at baseline, but not at the follow-ups, and immigrants were more adherent towards the self-management program than domestic born participants. Conclusion: These results are pioneer findings showing that it exists sociodemographic differences related to OA treatment.
Structure of South Africa’s agricultural trade

A detailed trade analysis was developed to assess South African agricultural trade trends and dynamics. Our approach combines an in-depth look at trading patterns of South African Agricultural trade with the application of a trend cycle’s decomposition (TCD), smoothing techniques, growth margin decomposition methods, Augmented Dickey-Fuller (ADF) regression and Box-pierce (Q) statics using bilateral trade data at the four digit standard international trade classification (SITC) level for 204 agricultural commodities from 2000 to 2011 annual data and a monthly data from 1992: 01 to 2011:12. Low diversification of agricultural export was observed and the market for South African agricultural exports depends on the EU market, while the importance of Asian markets has increased. South Africa’s importing partners are more diversify than exporting partners and agricultural trade in both commodities and trading partners for South Africa are intensive rather than extensive. This pose a great challenge for South Africa if it is to expand trade on an extensive scale. Without significant change in the agricultural production structure of South Africa, the country will be unable to capture the lion share of regional market opportunities created by import demand, even under a more integrated trade arrangement. Policies and interventions beyond trade arrangements, such as those targeting agricultural diversification and moving up the quality chain in exports, will be the key.
P ag e 2 9 2 METACOGNITIVE STRATEGY INSTRUCTION AND IELTS LISTENING PERFORMANCE : A COMPARISON BETWEENUSING MPS AND CALLA INSTRUCTION MODELS

Among the challenges instructors face when presented with the task of teaching, metacognitive strategies in ESL listening is the choice of instruction models to be adopted. This paper presents the findings of a research that compares the use of two instruction models to teach metacognitive strategies in L2 listening; the Metacognitive Pedagogical Sequence (MPS) and the Cognitive Academic Language Learning Approach (CALLA). A quasi-experimental research was carried out to compare their effects on the listening comprehension performance of Malaysian ESL learners (N=50) at a tertiary institution in Malaysia, using IELTS listening tests. The study aims to investigate if the two models would result in improvements to listeners’ listening comprehension performance across three levels of listening proficiency (high, intermediate and low). Posttest results show that listening comprehension performance using both models improved significantly compared to their pretest scores. However, when comparing between MPS and CALLA, there was no significant difference between their pretest -posttest improvements. In terms of listening proficiency levels, listeners in the intermediate and low levels made the most improvement and benefited the most from metacognitive strategy instruction. The paper concludes by making several recommendations with regard to their suitability of use in teaching L2 listening and their practical applications in teaching L2 unidirectional listening, as tested in IELTS and MUET.
