Abnormal gait detection with RGB-D devices using joint motion history features

Human gait has become of special interest to health professionals and researchers in recent years, not only due to its relation to a person's quality of life and personal autonomy, but also due to the involved cognitive process, since deviation from normal gait patterns can also be associated to neurological diseases. Vision-based abnormal gait detection can provide support to current human gait analysis procedures providing quantitative and objective metrics that can assist the evaluation of the geriatrician, while at the same time providing technical advantages, such as low intrusiveness and simplified setups. Furthermore, recent advances in RGB-D devices allow to provide low-cost solutions for 3D human body motion analysis. In this sense, this work presents a method for abnormal gait detection relying on skeletal pose representation based on depth data. A novel spatio-temporal feature is presented that provides a representation of a set of consecutive skeletons based on the 3D location of the skeletal joints and the motion's age. The corresponding feature sequences are learned using a machine learning method, namely BagOfKeyPoses. Experimentation with different datasets and evaluation methods shows that reliable detection of abnormal gait is obtained and, at the same time, an outstandingly high temporal performance is provided.
SULFATE REQUIREMENT FOR IRON OXIDATION BY THIOBACILLUS FERROOXIDANS

Lazaroff, Norman (British Columbia Research Council, Vancouver, B.C., Canada). Sulfate requirement for iron oxidation by Thiobacillus ferrooxidans. J. Bacteriol. 85:78–83. 1963. —The growth of Thiobacillus ferrooxidans is initially inhibited in media containing ferrous chloride in place of ferrous sulfate. This inhibition of growth is due to the requirement of a high relative proportion of sulfate ions to chloride (or other anions) for iron oxidation. Adaptation takes place, producing strains which are able to oxidize iron in media containing an initially unfavorable anionic composition. Adaptation is possibly due to the selection of spontaneous mutants capable of oxidizing iron in high chloride, low sulfate media. Such cells are found at a frequency of 10−5 of the population of unadapted cultures.

The Crosspoint-Queued Switch

This paper calls for rethinking packet-switch architectures by cutting all dependencies between the switch fabric and the linecards. Most single-stage packet-switch architectures rely on an instantaneous communication between the switch fabric and the linecards. Today, however, this assumption is breaking down, because effective propagation times are too high and keep increasing with the line rates. In this paper, we argue for a self-sufficient switch fabric by moving all the buffering from the linecards to the switch fabric. We introduce the crosspoint-queued (CQ) switch, a new buffered-crossbar switch architecture with large crosspoint buffers and no input queues, and show how it can be readily implemented in a single SRAM-based chip using current technology. For a crosspoint buffer size of one, we provide a closed-form throughput formula for all work-conserving schedules under uniform Bernoulli i.i. d. arrivals. Furthermore, we study the performance of the switch for larger buffer sizes and show that it nearly behaves as an ideal output-queued switch. Finally, we confirm our results using synthetic as well as trace-based simulations.
Concurrency control performance modeling: alternatives and implications

A number of recent studies have examined the performance of concurrency control algorithms for database management systems. The results reported to date, rather than being definitive, have tended to be contradictory. In this paper, rather than presenting “yet another algorithm performance study,” we critically investigate the assumptions made in the models used in past studies and their implications. We employ a fairly complete model of a database environment for studying the relative performance of three different approaches to the concurrency control problem under a variety of modeling assumptions. The three approaches studied represent different extremes in how transaction conflicts are dealt with, and the assumptions addressed pertain to the nature of the database system's resources, how transaction restarts are modeled, and the amount of information available to the concurrency control algorithm about transactions' reference strings. We show that differences in the underlying assumptions explain the seemingly contradictory performance results. We also address the question of how realistic the various assumptions are for actual database systems.
Longitudinal prospective evaluation of quality of life in adult patients before and one year after liver transplantation

We assessed the impact of liver transplantation (LT) on the quality of life (QOL) of French recipients 1 year after surgery. A French version of the questionnaire used by the National Institute of Diabetes and Digestive and Kidney Disease—Pittsburg, USA (NIDDK), was validated by the back‐translation method. Five QOL domains were evaluated: measures of disease, psychological distress, personal function, social function, and general health perception. Patients enrolled onto the waiting list completed the questionnaire before and 1 year after LT. Respondents were age‐ and gender‐matched with healthy subjects recruited from the general population (GP). One year after LT, the analysis of data from 67 consecutive patients showed dramatic improvement in the five domains. Compared with baseline, patients noted fewer disease‐related symptoms (P < .0001) and lower level of distress overall (P < .001). However, levels of distress caused by excess appetite (P < .01), trembling (P < .05), and headaches (P = .06) were more likely to increase than decrease. Twenty‐five percent of patients prevented by their disease from going to work before LT were no longer so limited at 1‐year follow‐up. General health perception improved remarkably, with seven times as many recipients reporting improved health as reporting worse health. A correlation was found between the pretransplantation severity of cirrhosis and the social and role function after LT (P < .05). In summary, the French version of the NIDDK questionnaire seems to be reliable. The results of transplant recipients were generally close to those of the general population. Although it is not a true return to normal status, it approaches it. (Liver Transpl 2003;9:703‐711.)
Spatial Distribution and Receptor Specificity of Zebrafish Kit System - Evidence for a Kit-Mediated Bi-Directional Communication System in the Preovulatory Ovarian Follicle

Consisting of Kit ligand and receptor Kit, the Kit system is involved in regulating many ovarian functions such as follicle activation, granulosa cell proliferation, and oocyte growth and maturation. In mammals, Kit ligand is derived from the granulosa cells and Kit receptor is expressed in the oocyte and theca cells. In the zebrafish, the Kit system contains two ligands (Kitlga and Kitlgb) and two receptors (Kita and Kitb). Interestingly, Kitlga and Kitb are localized in the somatic follicle cells, but Kitlgb and Kita are expressed in the oocyte. Using recombinant zebrafish Kitlga and Kitlgb, we demonstrated that Kitlga preferentially activated Kita whereas Kitlgb specifically activated Kitb by Western analysis for receptor phosphorylation. In support of this, Kitlgb triggered a stronger and longer MAPK phosphorylation in follicle cells than Kitlga, whereas Kitlga but not Kitlgb activated MAPK in the denuded oocytes, in agreement with the distribution of Kita and Kitb in the follicle and their specificity for Kitlga and Kitlgb. Further analysis of the interaction between Kit ligands and receptors by homology modeling showed that Kitlga-Kita and Kitlgb-Kitb both have more stable electrostatic interaction than Kitlgb-Kita or Kitlga-Kitb. A functional study of Kit involvement in final oocyte maturation showed that Kitlga and Kitlgb both suppressed the spontaneous maturation significantly; in contrast, Kitlgb but not Kitlga significantly promoted 17α, 20β-dihydroxy-4-pregnen-3-one (DHP) -induced oocyte maturation. Our results provided strong evidence for a Kit-mediated bi-directional communication system in the zebrafish ovarian follicle, which could be part of the complex interplay between the oocyte and the follicle cells in the development of follicles.
On the Computation of the Transitive Closure of Relational Operators

Query processing in the presence of recursively defined views usually involves some form of iteration. For example, computing the transitive closure of a tree involves iterating N times, where N is the depth of the tree, each time computing pairs of vertices that are one edge further apart than the pairs produced in the previous iteration. Applying a divide and conquer technique we devise algorithms that need a logarithmic number of iterations. Assuming that we are looking for complete materializations of the recursively defined relations we show both through analytical and experimental results that this approach is in many cases superior in performance than the Niteration algorithm
Changes in Participation After a Mild Stroke: Quantitative and Qualitative Perspectives

Abstract Purpose and Method: This descriptive study is aimed at documenting changes in participation level (accomplishment of daily activities and social roles) from quantitative (n = 35) and qualitative (n = 5) perspectives in individuals who have had a first “mild” stroke compared to their prestroke level. With advances in technology (e.g., increased use of thrombolitic therapy), the prevalence of mild stroke is expected to increase. Yet these strokes are rarely referred to rehabilitation, and little is known about the consequences of stroke on patients’ lives. Conclusion: Results of both methods confirmed significant impact of the stroke on participation level that is persistent even 6 months poststroke.
Intramolecular DNA quadruplexes with different arrangements of short and long loops

We have examined the folding, stability and kinetics of intramolecular quadruplexes formed by DNA sequences containing four G3 tracts separated by either single T or T4 loops. All these sequences fold to form intramolecular quadruplexes and 1D-NMR spectra suggest that they each adopt unique structures (with the exception of the sequence with all three loops containing T4, which is polymorphic). The stability increases with the number of single T loops, though the arrangement of different length loops has little effect. In the presence of potassium ions, the oligonucleotides that contain at least one single T loop exhibit similar CD spectra, which are indicative of a parallel topology. In contrast, when all three loops are substituted with T4 the CD spectrum is typical of an antiparallel arrangement. In the presence of sodium ions, the sequences with two and three single T loops also adopt a parallel folded structure. Kinetic studies on the complexes with one or two T4 loops in the presence of potassium ions reveal that sequences with longer loops display slower folding rates.
A dynamic interplay between phytohormones is required for fruit development, maturation, and ripening

Plant species that bear fruit often utilize expansion of an ovary (carpel) or accessory tissue as a vehicle for seed dispersal. While the seed(s) develop, the tissue(s) of the fruit follow a common progression of cell division and cell expansion, promoting growth of the fruit. Once the seed is fully developed, the fruit matures and the surrounding tissue either dries or ripens promoting the dissemination of the seed. As with many developmental processes in plants, plant hormones play an important role in the synchronization of signals between the developing seed and its surrounding fruit tissue(s), regulating each phase of fruit development. Following pollination, fruit set is achieved through a de-repression of growth and an activation of cell division via the action of auxin and/or cytokinin and/or gibberellin. Following fruit set, growth of the fruit is facilitated through a relatively poorly studied period of cell expansion and endoreduplication that is likely regulated by similar hormones as in fruit set. Once the seeds reach maturity, fruit become ready to undergo ripening and during this period there is a major switch in relative hormone levels of the fruit, involving an overall decrease in auxin, gibberellin, and cytokinin and a simultaneous increase in abscisic acid and ethylene. While the role of hormones in fruit set and ripening is well documented, the knowledge of the roles of other hormones during growth, maturation, and some individual ripening components is sketchy.

Stepping out of the Twilight? Assessing the Governance Implications of Land Titling and Regularization Programmes

This article engages with the discussions on the benefits and drawbacks of land titling programmes that seek to regularize informal urban settlements in developing countries. It is based on fieldwork in two neighbourhoods of Maputo, Mozambique, that are currently part of a municipal government regularization programme supported by the World Bank. The fieldwork explored an informal titling system administrated by the neighbourhood authorities upon which local residents rely to prevent land conflicts and to provide proof of residence. The findings add to the literature that demonstrates growing unease with a strictly dyadic formal/informal analysis of land occupation, and further queries the assumption that the state and the informal settler are diametrically opposed, with the former granting formal rights to the latter. In the process of these discussions, the article highlights the limited scholarly attention that has been granted to the governance implications of land titling programmes.
Optimization of queries with user-defined predicates

Relational databases provide the ability to store user-defined functions and predicates which can be invoked in SQL queries. When evaluation of a user-defined predicate is relatively expensive, the traditional method of evaluating predicates as early as possible is no longer a sound heuristic. There are two previous approaches for optimizing such queries. However, neither is able to guarantee the optimal plan over the desired execution space. We present efficient techniques that are able to guarantee the choice of an optimal plan over the desired execution space. The optimization algorithm with complete rank-ordering improves upon the naive optimization algorithm by exploiting the nature of the cost formulas for join methods and is polynomial in the number of user-defined predicates (for a given number of relations.) We also propose pruning rules that significantly reduce the cost of searching the execution space for both the naive algorithm as well as for the optimization algorithm with complete rank-ordering, without compromising optimality. We also propose a conservative local heuristic that is simpler and has low optimization overhead. Although it is not always guaranteed to find the optimal plans, it produces close to optimal plans in most cases. We discuss how, depending on application requirements, to determine the algorithm of choice. It should be emphasized that our optimization algorithms handle user-defined selections as well as user-defined join predicates uniformly. We present complexity analysis and experimental comparison of the algorithms.

Literature Views on Second Language Acquisition The Ways of Incorporating Interaction and Participation

Most current theories of second language acquisition and current views on methods and approaches to teaching English as a second language place a high value on student participation and interaction in the language classroom. This interaction may be between teacher and student and/or student and student. Despite this, in many English classrooms around the world, students have very few opportunities to interact in the second language. In this paper, using the literature on second language acquisition research and methodology to prepare a case which highlights why teachers and course designers should find ways to incorporate second language interaction and student participation in their language classes despite the practical difficulties they may face.
Vitamin D, cardiovascular disease and mortality

A poor vitamin D status, i.e. low serum levels of 25‐hydroxyvitamin D [25(OH)D], is common in the general population. This finding is of concern not only because of the classic vitamin D effects on musculoskeletal outcomes, but also because expression of the vitamin D receptor (VDR) and vitamin D metabolizing enzymes in the heart and blood vessels suggests a role of vitamin D in the cardiovascular system. VDR‐knockout mice suffer from cardiovascular disease (CVD), and various experimental studies suggest cardiovascular protection by vitamin D, including antiatherosclerotic, anti‐inflammatory and direct cardio‐protective actions, beneficial effects on classic cardiovascular risk factors as well as suppression of parathyroid hormone (PTH) levels. In epidemiological studies, low levels of 25(OH)D are associated with increased risk of CVD and mortality. Data from randomized controlled trials (RCTs) are sparse and have partially, but not consistently, shown some beneficial effects of vitamin D supplementation on cardiovascular risk factors (e.g. arterial hypertension). We have insufficient data on vitamin D effects on cardiovascular events, but meta‐analyses of RCTs indicate that vitamin D may modestly reduce all‐cause mortality. Despite accumulating data suggesting that a sufficient vitamin D status may protect against CVD, we still must wait for results of large‐scale RCTs before raising general recommendations for vitamin D in the prevention and treatment of CVD. In current clinical practice, the overall risks and costs of vitamin D supplementation should be weighed against the potential adverse consequences of untreated vitamin D deficiency.

Making Modern Lives: Subjectivity, Schooling, and Social Change

Making Modern Lives looks at how young people shape their lives as they move through their secondary school years and into the world beyond. It explores how they develop dispositions, attitudes, identities, and orientations in modern society. Based on an eight-year study consisting of more the 350 in-depth interviews with young Australians from diverse backgrounds, the book reveals the effects of schooling and of local school cultures on young people's choices, future plans, political values, friendships, and attitudes toward school, work, and sense of self. Making Modern Lives uncovers who young people are today, what type of identities and inequalities are being formed and reformed, and what processes and politics are at work in relation to gender, class, race, and the framing of vocational futures.
