Exercise Recognition for Kinect-based Telerehabilitation

Summary Background: An aging population and people’s higher survival to diseases and traumas that leave physical consequences are challenging aspects in the context of an efficient health management. This is why telerehabilitation systems are being developed, to allow monitoring and support of physiotherapy sessions at home, which could reduce healthcare costs while also improving the quality of life of the users. Objectives: Our goal is the development of a Kinect-based algorithm that provides a very accurate real-time monitoring of physical rehabilitation exercises and that also provides a friendly interface oriented both to users and physiotherapists. Methods: The two main constituents of our algorithm are the posture classification method and the exercises recognition method. The exercises consist of series of movements. Each movement is composed of an initial posture, a final posture and the angular trajectories of the limbs involved in the movement. The algorithm was designed and tested with datasets of real movements performed by volunteers. We also explain in the paper how we obtained the optimal values for the trade-off values for posture and trajectory recognition. Results: Two relevant aspects of the algorithm were evaluated in our tests, classification accuracy and real-time data processing. We achieved 91.9% accuracy in posture classification and 93.75% accuracy in trajectory recognition. We also checked whether the algorithm was able to process the data in real-time. We found that our algorithm could process more than 20,000 postures per second and all the required trajectory data-series in real-time, which in practice guarantees no perceptible delays. Later on, we carried out two clinical trials with real patients that suffered shoulder disorders. We obtained an exercise monitoring accuracy of 95.16%. Conclusions: We present an exercise recognition algorithm that handles the data provided by Kinect efficiently. The algorithm has been validated in a real scenario where we have verified its suitability. Moreover, we have received a positive feedback from both users and the physiotherapists who took part in the tests.
Representation of the ipsilateral visual field in the transition zone between areas 17 and 18 of the cat's cerebral cortex

Abstract The representation of the visual field in the architectonically defined transition zone between areas 17 and 18 of cat cerebral cortex was assessed by recording the activities and plotting the receptive fields of neurons at 2327 sites along 148 electrode penetrations made in 19 cats. The results show that the transition zone contains a significant representation of the ipsilateral visual hemifield although not all elevations in the visual field represented to the same extent. The shape of the field region represented resembles an hour glass, for the region represented is narrowest on the 0-deg horizontal meridian and increasingly wider at progressively more positive and negative elevations. When receptive-field centers are considered, the extent of the representation reaches to -2.5 deg on the 0-deg horizontal meridian and to 10 or more degrees towards the field periphery. When receptive-field areas are considered, the representation at the 0-deg horizontal meridian extends to -3.6 deg and to beyond 20 deg at other elevations. In contrast, the visual-field representations in flanking areas 17 and 18 are essentially limited to the contralateral hemifield. The presence of a distinct representation of part of the ipsilateral hemifield in the transition zone suggests that the zone may have connections distinctly different from those of the adjacent areas. The observations bear on the problems of understanding the visual pathways in hypopigmented cats and binocular disparity mechanisms about the midline.
Automatic I/O Scheduler Selection through Online Workload Analysis

I/O performance is a bottleneck for many workloads. The I/O scheduler plays an important role in it. It is typically configured once by the administrator and there is no selection that suits the system at every time. Every I/O scheduler has a different behavior depending on the workload and the device. We present a method to select automatically the most suitable I/O scheduler for the ongoing workload. This selection is done online, using a workload analysis method with small I/O traces, finding common I/O patterns. Our dynamic mechanism adapts automatically to one of the best schedulers, sometimes achieving improvements on I/O performance for heterogeneous workloads beyond those of any fixed configuration (up to 5%). This technique works with any application and device type (RAID, HDD, SSD), as long as we have a system parameter to tune. It does not need disk simulations or hardware models, which are normally unavailable. We evaluate it in different setups, and with different benchmarks.
Robotics and the Lessons of Cyberlaw

Two decades of analysis have produced a rich set of insights as to how the law should apply to the Internet’s peculiar characteristics. But, in the meantime, technology has not stood still. The same public and private institutions that developed the Internet, from the armed forces to search engines, have initiated a significant shift toward robotics and artificial intelligence. This article is the first to examine what the introduction of a new, equally transformative technology means for cyberlaw and policy. Robotics has a different set of essential qualities than the Internet and, accordingly, will raise distinct legal issues. Robotics combines, for the first time, the promiscuity of data with the capacity to do physical harm; robotic systems accomplish tasks in ways that cannot be anticipated in advance; and robots increasingly blur the line between person and instrument.Robotics will prove “exceptional” in the sense of occasioning systematic changes to law, institutions, and the legal academy. But we will not be writing on a clean slate: Many of the core insights and methods of cyberlaw will prove crucial in integrating robotics, and perhaps whatever technology follows.
Limits of increasing the performance of Industrial Ethernet protocols

The evolution of industrial communication inexorably moves to Industrial Ethernet networks. One important reason for using Ethernet at the shop floor is to participate on the continuous advancements of standard Ethernet. Thus it seems to be the logical next step to change the bit rate from Fast Ethernet to Gigabit Ethernet to achieve better performance. The question is, how the cycle time as a relevant performance metrics of industrial automation systems can profit from increasing the bit rate to 1 Gbps. Because of its importance for the industrial automation domain this paper focuses on line topology. The analysis is based on EtherCAT and PROFINET, which are two popular representatives of different architectures for high performance Industrial Ethernet networks.
Improved prediction of prostate cancer recurrence based on an automated tissue image analysis system

Prostate tissue characteristics play an important role in predicting the recurrence of prostate cancer. Currently, experienced pathologists manually grade these prostate tissues using the GIeason scoring system, a subjective approach which summarizes the overall progression and aggressiveness of the cancer. Using advanced image processing techniques, Aureon Biosciences Corporation has developed a proprietary image analysis system (MAGIC/spl trade/), which here is specifically applied to prostate tissue analysis and designed to be capable of processing a single prostate tissue hematoxylin-and-eosin (H&E) stained image and automatically extracting a variety of raw measurements (spectral, shape, etc.) of histopathological objects along with spatial relationships amongst them. In the context of predicting prostate cancer recurrence, the performance of the image features is comparable to that achieved using the GIeason scoring system. Moreover, an improved prediction rate is observed by combining the GIeason scores with the image features obtained using MAGIC/spl trade/, suggesting that the image data itself may possess information complementary to that of GIeason scores.
The organization of neural inputs to the medial preoptic nucleus of the rat

There is general agreement that the medial preoptic nucleus (MPN) receives projections from widespread regions of the brain, although there are significant discrepancies in the literature with regard to certain specific inputs. Therefore, we have reexamined the inputs to this nucleus with both retrograde and anterograde axonal transport techniques. First, injections of the retrograde tracers true blue, SITS, or wheat germ agglutinin were made into the region of the MPN and the distribution of retrogradely labeled cells was charted. Then, autoradiographic material was used to confirm the results of the retrograde studies, to identify the route taken by fibers projecting to the MPN, and to describe the distribution of projections with respect to the three cytoarchitectonic subdivisions of the nucleus.
Semi-supervised Kernel Logistic Regression and Its Extension to Active Learning Based on A-Optimality

The purpose of this paper is to introduce new approaches for kernel logistic regression (KLR) in a semi-supervised setting. Using the special structure of Laplacian kernel matrices, we propose new formulations which minimize the negative log likelihood of the KLR model efficiently. Also, we propose new algorithms for pool-based active learning based on A-optimality in which the semi-supervised KLR is used to estimate the class probabilities. We show that the active learning algorithms can be carried out in the fea- ture space defined by the associated kernel matrices. We give experimental results showing that the proposed active learning method generate accurate classifiers using a fewer number of labeled data points compared with the random queries.
Valoración económica de la imagen de un destino

This work develops a new methodology for economic evaluation of destination image, adding two main advantages over the traditional methods used before: (1) it allows to differentiate the geographical destination image from the subjective experience holydays of the tourist in that destination. Thus, it facilitates the differentiation between the destination perceived image measure, the experience perceived image and finally, the experience perceived image influenced by the des - tination perceived image; and (2) it allows the economic evaluation of the destination image and its attributes. The results show academic and practical implications for the economic evaluation of the destination investment to increase their competitiveness in the market, and facilitate to improve marketing planning to increase the destination image.
Newly developed integration method for biomedical implants using flexible polymer cable

This paper presented an integration method for biomedical implants by using solder bonding and highly flexible polyimide (PI) cable. The proposed integration method can overcame the problems in flexible cable assembly before. It can achieve a small form, and better reliability, and is easier for fragile MEMS device bonding by using solder bonding. Therefore, it is suitable for various MEMS devices integration. The effect of the metal materials and reliability of the flexible cable with thin metal trace were studied. SEM and TEM/EDX analysis were performed to evaluate the boning interface microstructures. Electrical tests were carried out to study the resistance of the interconnects. Thermal cycling test with temperature range of −40/+125ଌ with 15mins dwell for 500 cycles was used to evaluate the reliability properties of the interconnects. The results showed good bonding interface, low electrical resistance and there were no major changes in resistance during thermal cycling. Hence, it implied that the interconnections were highly stable and reliable by using the proposed bonding method.
Absent yet popular? Explaining news visibility of Members of the European Parliament

Members of the European Parliament (MEPs) represent their citizens in European Union policy making, having the power to approve, amend or reject the near majority of legislation. The media inform EU citizens about their representatives and are able to hold them publicly accountable. However, we know little about whether, and to what extent, MEPs are visible in the news. This study investigates the visibility of MEPs in national broadsheets in Britain, France, the Netherlands, Germany and Italy. It seeks to explain individual-level variation by employing an original dataset of news visibility of 302 MEPs over a period of 25 months (September 2009-September 2011) and tests the applicability of the news values and mirror theories in the context of supranational politics. The results show that political office, length of tenure and domestic party leadership have a positive effect. Legislative activities have a mixed effect on MEP news visibility. Attendance negatively affects news visibility, while non-attached MEPs receive more news coverage. In short, despite the core supranational nature of EP legislative politics, MEP news visibility primarily depends on journalists’ domestic considerations. This informs both our understanding of MEP parliamentary behaviour and journalism studies in the context of the EU.
Differential expression of proliferation-associated molecules in individual micrometastatic carcinoma cells.

BACKGROUND The development of monoclonal antibodies (MAbs) to cytokeratins, which are integral components of the epithelial cytoskeleton, has made possible immunocytochemical detection of epithelial tumor cells. Importantly, this technique allows the detection of epithelial tumor cells that have metastasized from primary adenocarcinomas to secondary sites such as the bone marrow. PURPOSE The aim of the study was not only to detect micrometastatic cells in bone marrow, but also to assess the expression of nuclear proliferation markers (Ki-67 and p120) and the erbB2 oncogene (also known as ERBB2) in these cells and, thus, hopefully improve prognostic precision. METHODS Bone marrow aspirates were obtained from both sides of the upper iliac crest of 532 patients having definitive diagnoses of either breast or gastrointestinal cancer. The presence of micrometastatic epithelial tumor cells in bone marrow was assayed using the MAb cytokeratin 2 (CK2) to cytokeratin component 18 (CK18), in combination with the alkaline phosphatase-anti-alkaline phosphatase immunostaining technique. After primary screening of all marrow samples with MAb CK2, representative subgroups of CK18+ samples were selected for co-labeling with MAbs either to ErbB (n = 16), ErbB2 (n = 121), Ki-67 (n = 33), or p120 (n = 36) protein. An alternative labeling protocol based on the combination of immunogold and immunoenzymatic techniques was utilized to confirm the results derived from immunoenzymatic double staining. RESULTS In total, single CK18-positive tumor cells were detected in 180 (33.8%) of 532 bone marrow aspirates, with few differences among patients with breast or gastrointestinal cancer in TNM stage M0 (i.e., no distant metastasis). In patients with overt metastasis (stage M1), however, the incidence of metastatic cells in marrow increased to 73.7% in breast cancer, 52.5% in gastric cancer, and 39.0% in colon cancer. Whereas expression of Ki-67 or p120 on micrometastatic cells was observed only in 11 (15.9%) of 69 cancer patients analyzed, ErbB2+/CK18+ cells were found in 48 (67.6%) of 71 breast cancer patients and 14 (28.0%) of 50 patients with gastrointestinal cancer (P = .0001). The incidence of ErbB2+/CK18+ cells was positively correlated with the clinical stage of tumor progression. CONCLUSIONS The high incidence of ErbB2 expression on micrometastatic breast cancer cells in the bone marrow suggests that these cells might have been positively selected during early stages of metastasis. The majority of these cells appear to be in a dormant state of cell growth. IMPLICATIONS Although support from clinical follow-up is still needed, this study demonstrates that, beyond the mere presence of micrometastatic cells in bone marrow, useful prognostic information can be obtained by analysis of additional cell growth markers.
Motivation and personality: The affiliation motive

DERIVATION AND ADMINISTRATION OF THE FANTASY MEASURE OF N AFFILIATION Affiliative motivation is defined as a concern over establishing, maintaining, or restoring a positive affective relationship with another person or group of persons (Heyns, Veroff, & Atkinson, 1958). The system for scoring the need for affiliation ( n Aff) from imaginative thought content (see chapter 14) was developed by comparing stories written by college men after they had been socially evaluated by their peers with stories written under neutral conditions (Atkinson, Heyns, & Veroff, 1954; Shipley & Veroff, 1952). Similar evaluative conditions were shown to arouse affiliative concerns in stories written by women (Rosenfeld & Franklin, 1966). The same scoring system is used for males and females. The procedure for eliciting associative thought content that can be coded for n Affiliation is identical to that used for the achievement and power motives. This procedure is sometimes referred to as the Picture-Story Exercise (PSE) and requires subjects to write 5-minute stories to a series of four to six pictures like those of the Thematic Apperception Test (TAT). It is recommended that the PSE be administered by an experimenter who behaves in a relaxed, friendly, and approving manner (Lundy, 1988). It is also advisable to avoid administering the PSE immediately after an objective test or cognitive task (Lundy, 1988).
A Preliminary Research on the Lifestyle of International Students

The focus of this study is to explore the lifestyle of international students and also the difficulties faced by them due to the language barrier (difficulty in learning the Chinese language) in Taiwan. Motivation for this study comes from the increasing number of international students, and the related educational policy settings of the government in Taiwan. In general, these international students are very focused on their studies, they foster a close relationship with their families and firmly believe that this family support motivates them to perform better and learn more. However, language seems to be a major barrier for them while adapting to the life in Taiwan, thereby, making it difficult for the students to comprehend the local news and gather information. Moreover, they are also not used to the local food, which might be one of the reasons that may motivate them to return to their own countries/homelands. The purpose of this study is: (1) to determine the relationship between the variables, population statistics and lifestyle; and (2) to understand the lifestyle of international students. We classified lifestyle into seven domains with the help of factor analysis: optimist-oriented, participation-oriented, fashion-oriented, nostalgia-oriented, benefit-oriented, independence-oriented and actuality-oriented. We also analyzed the demographics data and found that there are significances in the dimensions related to participation-oriented, fashion-oriented, nostalgia-oriented, benefit-oriented, independence-oriented and actuality-oriented lifestyle domains. Furthermore, research shows that international students, who were very participation-oriented, mainly chose to live in dormitories, as they could keep in touch with people and also had access to necessary information. Further, marriage also influences their level of participation.
Thirty-Day Mortality After Infection Among Persons With Severe Mental Illness: A Population-Based Cohort Study in Denmark.

OBJECTIVE Persons with severe mental illness die 15-20 years earlier on average than persons without severe mental illness. Although infection is one of the leading overall causes of death, no studies have evaluated whether persons with severe mental illness have a higher mortality after infection than those without. METHOD The authors studied mortality rate ratios and cumulative mortality proportions after an admission for infection for persons with severe mental illness compared with persons without severe mental illness by linking data from Danish national registries. RESULTS The cohort consisted of all persons hospitalized for infection during the period 1995-2011 in Denmark (N=806,835), of whom 11,343 persons had severe mental illness. Within 30 days after an infection, 1,052 (9.3%) persons with a history of severe mental illness and 58,683 (7.4%) persons without a history of severe mental illness died. Thirty-day mortality after any infection was 52% higher in persons with severe mental illness than in persons without (mortality rate ratio=1.52, 95% CI=1.43-1.61). Mortality was increased for all infections, and the mortality rate ratios ranged from 1.27 (95% CI=1.15-1.39) for persons hospitalized for sepsis to 2.61 (95% CI=1.69-4.02) for persons hospitalized for CNS infections. Depending on age, 1.7 (95% CI=1.2-2.2) to 2.9 (95% CI=2.0-3.7) more deaths were observed within 30 days after an infection per 100 persons with a history of severe mental illness compared with 100 persons without such a history. CONCLUSIONS Persons with severe mental illness have a markedly elevated 30-day mortality after infection. Some of these excess deaths may be prevented by offering individualized and targeted interventions.
Power distance and its moderating role in the relationship between situational job characteristics and job satisfaction: An empirical analysis using different cultural measures

Purpose – Power distance describes a central facet of national culture, because it influences the acceptance and endorsement of job characteristics related to status and power. This has major implications for international human resource management, because the importance of different situational job characteristics for employee job satisfaction should differ across cultures. The purpose of this paper is to analyse if and how national power distance levels moderate different situational job characteristics’ influence on job satisfaction. Design/methodology/approach – The authors refer to three approaches to culture: the frameworks of Hofstede and GLOBE as well as to current scores provided in a meta-analysis. The empirical findings are derived using regression analyses on a sample covering 16 nations. Findings – The results are convincing regarding the basic job satisfaction driver model not involving culture. However, the results on power distance’s impact as well as its moderating role are strongly depe.
Twenty-First Century Challenges for In Vitro Neurotoxicity

During the last 40 years, studies incorporating in vitro methodologies have greatly advanced our understanding of human nerve cell biology. Attempts have been made to apply these to investigations of neurotoxicity. Due to the complexity of the nervous system, underpinned by an array of integrated interactions between a host of cell types, it is concluded that, at present, alternative neural models are most successful in determining the underlying mechanisms which can cause perturbation of normal functioning of the nervous system, both in adults and during the embryonic period. The use of tiered batteries of test models has been proposed in screening programmes for neurotoxicity, with the generation of much encouraging data in laboratories across the globe. This review aims to discuss the development of neural alternatives, considers the various model systems available, and highlights specific neuronal endpoints which can be tested, in addition to the cytotoxic evaluation of neuronal viability. Developments in molecular and stem cell biology, which are appropriate to neural tissue, and which offer the prospect of exciting advances for the next decade, are cited.
