Going Deeper into Action Recognition: A Survey

We provide a detailed review of the work on human action recognition over the past decade. We refer to “actions” as meaningful human motions. Starting with methods that are based on handcrafted representations, we review the impact of revamped deep neural networks on action recognition. We follow a systematic taxonomy of action recognition approaches to present a coherent discussion over their improvements and fall-backs.
Distributed trajectory estimation with privacy and communication constraints: A two-stage distributed Gauss-Seidel approach

We propose a distributed algorithm to estimate the 3D trajectories of multiple cooperative robots from relative pose measurements. Our approach leverages recent results [1] which show that the maximum likelihood trajectory is well approximated by a sequence of two quadratic subproblems. The main contribution of the present work is to show that these subproblems can be solved in a distributed manner, using the distributed Gauss-Seidel (DGS) algorithm. Our approach has several advantages. It requires minimal information exchange, which is beneficial in presence of communication and privacy constraints. It has an anytime flavor: after few iterations the trajectory estimates are already accurate, and they asymptotically convergence to the centralized estimate. The DGS approach scales well to large teams, and it has a straightforward implementation. We test the approach in simulations and field tests, demonstrating its advantages over related techniques.
Evolution of a VFX voxel tool

High-resolution voxel rendering is no longer the pipe dream it once was. In the age of multi-gigabyte RAM, voxels are finding an ever-increasing role in creating cutting-edge visual effects. Digital Domain has developed a unique, animator-friendly way of working with voxels that is revolutionizing the way volumetric effects are done.
Do people with recurrent back pain constrain spinal motion during seated horizontal and downward reaching?

BACKGROUND
Although the effect of symptomatic back pain on functional movement has been investigated, changes to spinal movement patterns in essentially pain-free people with a history of recurrent back pain are largely unreported. Reaching activities, important for everyday and occupational function, often present problems to such people, but have not been considered in this population. The purpose of this study was to compare the amplitude and timing of spinal and hip motions during two, seated reaching activities in people with and without a history of recurrent low back pain (RLBP).


METHODS
Spinal and hip motions during reaching downward and across the body, in both directions, were tracked using electromagnetic sensors. Analyses were conducted to explore the amplitudes, velocities and timings of 3D segmental movements and to compare controls with subjects with recurrent, but asymptomatic lumbar or lumbosacral pain.


FINDINGS
We detected significant differences in the amplitude and timing of movement in the lower thoracic region, with the RLBP group restricting movement and demonstrating compensatory increased motion at the hip. The lumbar region displayed no significant between-group differences. The order in which the spinal segments achieved peak velocity in cross-reaching was reversed in RLBP compared to controls, with lumbar motion leading in controls and lagging in RLBP.


INTERPRETATION
Subjects with a history of RLBP show a number of altered kinematic features during reaching activities which are not related to the presence or intensity of pain, but which suggest adaptive changes to movement control.
Guiding Novice Web Workers in Making Image Descriptions Using Templates

This article compares two methods of employing novice Web workers to author descriptions of science, technology, engineering, and mathematics images to make them accessible to individuals with visual and print-reading disabilities. The goal is to identify methods of creating image descriptions that are inexpensive, effective, and follow established accessibility guidelines. The first method explicitly presented the guidelines to the worker, then the worker constructed the image description in an empty text box and table. The second method queried the worker for image information and then used responses to construct a template-based description according to established guidelines. The descriptions generated through queried image description (QID) were more likely to include information on the image category, title, caption, and units. They were also more similar to one another, based on Jaccard distances of q-grams, indicating that their word usage and structure were more standardized. Last, the workers preferred describing images using QID and found the task easier. Therefore, explicit instruction on image-description guidelines is not sufficient to produce quality image descriptions when using novice Web workers. Instead, it is better to provide information about images, then generate descriptions from responses using templates.
Dorsal vaginal graft urethroplasty for female urethral stricture disease.

UNLABELLED
Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Female urethral stricture disease has been described for almost 200 years. The symptoms of female stricture disease may range from clinically insignificant to severe and debilitating with the exact aetiology being unclear. No strict criteria for diagnosis have been established with the diagnosis often relying on a combination of presenting symptoms and objective findings. Initial therapy for female urethral stricture disease has often rested on urethral dilatations and self-intermittent catheterisation with surgery reserved for patients that failed conservative measures. Female urethroplasty currently is a topic of increasing attention with multiple surgical approaches described including use of both grafts (vaginal wall, buccal mucosal membrane, lingual mucosa, and labia minus) and flaps (vaginal vestibule, anterior vagina, and lateral vagina). We describe our approach to female urethroplasty using a suprameatal (dorsal) approach (described by Tsivian and Sidi) with an autologous vaginal epithelium inlay graft. The technique and modern approaches to female urethroplasty are contrasted and discussed. The success of the approach including continence rates and lack of need for long-term self-intermittent catheterisation is noted.


OBJECTIVE
• To review the technique and outcomes of using a dorsal vaginal graft to perform urethroplasty for the treatment of urethral strictures in women.


PATIENTS AND METHODS
• This is a retrospective chart review of 11 women who were treated with a dorsal vaginal graft urethroplasty by one surgeon. • All women underwent preoperative evaluation that included history, physical examination, fluoro-urodynamics and urethral calibration. • After surgery interviews, physical examinations, and urinary flow and postvoid residual urine volumes (PVRs) were obtained.


RESULTS
• In all, 11 women who had undergone dorsal vaginal graft urethroplasty were identified for review. The mean (range) age was 60.6 (39-75) years. The mean (range) follow-up was 22.7 (6-46) months. • There were no cases of new onset stress urinary incontinence. The mean PVRs before and after surgery were 187.1 mL and 75.8 mL, respectively (P = 0.003). The mean urinary flows before and after surgery were 7.3 mL/s and 21.8 mL/s, respectively (P = 0.001). • No patient has required repeat surgery. • Self-reporting satisfaction scores using the Patient Global Impression of Improvement showed that four patients scored 1 (very much better), three scored 2 (much better), two patients scored 3 (a little better), and one scored 4 (no change). Only one patient scored a 5 (worse).


CONCLUSION
• Dorsal graft urethroplasty with vaginal mucosa may be considered as a first-line option for definitive management of female urethral stricture disease. No consensus exists for the surgical treatment of female urethral stricture disease.
Dandies : fashion and finesse in art and culture

Dandies: Fashion and Finesse in Art and Culture considers the visual languages, politics, and poetics of personal appearance. Dandyism has been most closely associated with influential caucasian Western men-about-town, epitomized by the 19th century style-setting of Oscar Wilde and by Tom Wolfe's white suits. The essays collected here, however, examine the spectacle and workings of dandyism to reveal that these were not the only dandies. On the contrary, art historians, literary and cultural historians, and anthropologists identify unrecognized dandies flourishing among early 19th century Native Americans, in Soviet Latvia, in Africa, throughout the African-American diaspora, among women, and in the art world. Moving beyond historical and fictional accounts of dandies, this volume juxtaposes theoretical models with evocative images and descriptions of clothing in order to link sartorial self-construction with artistic, social, and political self-invention. Taking into consideration the vast changes in thinking about identity in the academy, Dandies provides a compelling study of dandyism's destabilizing aesthetic enterprise.

Interpreting SentiWordNet for Opinion Classification

We describe a set of tools, resources, and experiments for opinion classification in business-related datasources in two languages. In particular we concentrate on SentiWordNet text interpretation to produce word, sentence, and text-based sentiment features for opinion classification. We achieve good results in experiments using supervised learning machine over syntactic and sentiment-based features. We also show preliminary experiments where the use of summaries before opinion classification provides competitive advantage over the use of full documents.
Mining the Web to suggest concepts during concept mapping

The most challenging aspect of constructing a concept map is not coming up with the list of concepts to include, but linking the concepts into meaningful propositions creating a coherent structure that reflects the learner’s understanding of a domain. We present an algorithm that, during the process of concept mapping, takes the partially constructed map as input to mine the web, and presents to the user a list of suggested concepts that are relevant to the map under construction. Testing a preliminary implementation of the algorithm with a set of users during a concept-mapping workshop seems to validate its viability. Depending on the size of the suggestion list, the algorithm presented on average between 47% and 69% of the concepts in the final maps before the users added them to the map, showing that the algorithm is able to retrieve concepts relevant to the concept mapping effort.
The Factors Affecting the Development of National Identity as South Korean in North Korean Refugees Living in South Korea

OBJECTIVE
This study aims to observe the factors that influence the development of national identity of North Korean refugees who have resettled in South Korea.


METHODS
The study population was comprised of 500 North Korean refugees who immigrated to South Korea in 2007. The variables measured national identity as South Korean, a scale for discrimination perceived during daily life, a social for supporting social network, a for childhood trauma experience, traumatic experiences in North Korea, and traumatic experiences during the escape process. Factor analysis was conducted on the result from the scale for national identity as South Korean which produced 4 factors including national consciousness, positive emotions, positive values, and negative values. Multiple regression was done to identify how variables such as demographic data, discrimination, social network, and past trauma had influenced each of 4 factors.


RESULTS
National identity was negatively related by traumatic experience during childhood, perceived discrimination, and positively influenced by social networks. Positive emotion was related negatively to education level in North Korea and perceived discrimination, but positively related to traumatic experiences in North Korea. Negative value was related positively age and perceived discrimination but negatively related to supporting social network.


CONCLUSION
The results of this study suggests that promoting social networks, decreasing discrimination and healing past traumas were important factors for North Korean refugees in South Korea to facilitate a new national identity as a South Korean.
Design and Implementation of Push Notification System Based on the MQTT Protocol

This paper described a method of pushing notification system based on the MQTT protocol. It can be used to solve the problem of instant pushing various messages from the server to the mobile client. This method is suitable for developing the smartphone applications. This paper also carried out research and design on the realization of MQTT protocol. With support of the proxy server message broker, the protocol put forward solutions for the server sending the specified messages to the specified mobile devices and the mobile clients receiving pushed messages from the server.
Intelligent legged climbing service robot for remote maintenance applications in hazardous environments

-Wheeled-tracked vehicles are undoubtedly the most popular means of transportation. However, these vehicles are mainly suitable for relatively flat terrain. Legged vehicles, on the other hand, have the potential to handle wide variety of terrain. Robug IIs is a legged climbing robot designed to work in relatively unstructured and rough terrain. It has the capability of walking, climbing vertical surfaces and performing autonomous floor to wall transfer. The sensing technique used in Robug IIs is mainly tactile and ultrasonic sensing. A set of reflexive rules have been developed for the robot to react to the uncertainty of the working environment. The robot also has the intelligence to seek and verify its own foot-holds. It is envisaged that the main application of robot is for remote inspection and maintenance in hazardous environments. Keywords—Legged robot, climbing service robot, insect inspired robot, pneumatic control, fuzzy logic.
On the Scale-Space Theorem of Chen and Yan

Chen and Yan presented (ibid., vol.11, p.694-700, 1989) a theorem concerning zero crossings of boundary curvature under morphological openings. In this correspondence, we show by means of a counterexample a flaw in this theorem and suggest how the theorem may be modified to make it correct.
Spectral State Compression of Markov Processes

Model reduction of the Markov process is a basic problem in modeling statetransition systems. Motivated by the state aggregation approach rooted in control theory, we study the statistical state compression of a finite-state Markov chain from empirical trajectories. Through the lens of spectral decomposition, we study the rank and features of Markov processes, as well as properties like representability, aggregatability and lumpability. We develop a class of spectral state compression methods for three tasks: (1) estimate the transition matrix of a low-rank Markov model, (2) estimate the leading subspace spanned by Markov features, and (3) recover latent structures of the state space like state aggregation and lumpable partition. The proposed methods provide an unsupervised learning framework for identifying Markov features and clustering states. We provide upper bounds for the estimation errors and nearly matching minimax lower bounds. Numerical studies are performed on synthetic data and a dataset of New York City taxi trips. ∗Anru Zhang is with the Department of Statistics, University of Wisconsin-Madison, Madison, WI 53706, E-mail: anruzhang@stat.wisc.edu; Mengdi Wang is with the Department of Operations Research and Financial Engineering, Princeton University, Princeton, NJ 08544, E-mail: mengdiw@princeton.edu. †

Policies allowing family presence during resuscitation and patterns of care during in-hospital cardiac arrest.

BACKGROUND
A growing number of hospitals have begun to implement policies allowing for family presence during resuscitation (FPDR). However, the overall safety of these policies and their effect on resuscitation care is unknown.


METHODS AND RESULTS
We conducted an observational cohort study of 252 hospitals in the United States with 41,568 adults with cardiac arrest. Multivariable hierarchical regression models were used to evaluate patterns of care at hospitals with and without an FPDR policy. Primary outcomes included return of spontaneous circulation and survival to discharge. Secondary outcomes included resuscitation quality, interventions, and facility-reported potential resuscitation systems errors. There were no significant differences in facility characteristics between hospitals with and without an FPDR policy, nor were there significant differences in return of spontaneous circulation (adjusted risk ratio, 1.02; 95% confidence interval, 0.95-1.06) or survival to discharge (adjusted risk ratio, 1.05; 95% confidence interval, 0.95-1.15). There was a small, borderline significant decrease in the mean time to defibrillation at hospitals with an FPDR policy compared with hospitals without the policy (mean difference, 0.32 minutes; 95% confidence interval, -0.01 to 0.64). Resuscitation quality, interventions, and facility-reported potential resuscitation systems errors did not meaningfully differ between hospitals with and without an FPDR policy.


CONCLUSIONS
Hospitals with an FPDR policy generally have no statistically significant differences in outcomes and processes of care as hospitals without this policy, suggesting such policies may not negatively affect resuscitation care. Further study is warranted about the direct effect of FPDR attempts on adult patients with an in-hospital cardiac arrest and their families.
USE OF MOLECULAR MARKERS FOR EVALUATION OF GENETIC DIVERSITY AND IN ANIMAL PRODUCTION

INTRODuCTION Genetic markers provide information about allelic variation at a given locus. The increasing availability of molecular markers in farm animals allows the detailed analyses and evaluation of genetic diversity and furthermore the detection of genes influencing economically important traits. The majority of molecular markers used nowadays with high-throughput systems are microsatellite markers (simple tandem repeat, STR). Variable number of tandem repeats (VNTRs), random amplified polymorphic DNA (RAPD) markers, single strand conformation polymorphisms (SSCPs), restriction fragment length polymorphisms (RFLPs) and amplified fragment length polymorphisms (AFLPs) markers are not commonly applied in farm animals. Additionally within diversity and phylogeny studies specific mtDNA and Y chromosome markers are used for the identification of maternal and paternal lineages. Beyond diversity studies molecular markers are also used for mapping quantitative trait loci (QTL) and within marker assisted selection (MAS). Until recently microsatellites were the markers used for mapping quantitative trait loci for production and functional traits in farm animals (Hiendleder et al., 2003; Kühn et al., 2003) and tightly linked markers are used for marker assisted selection in practise. They are also the prerequisite for the identification of positional and functional candidate genes responsible for quantitative traits. The detailed use of molecular markers for the evaluation of genetic diversity and identification of economically important traits in animal production is presented on the basis of different examples.
Survival prediction for terminally ill cancer patients: revision of the palliative prognostic score with incorporation of delirium.

PURPOSE
An existing and validated palliative prognostic (PaP) score predicts survival in terminally ill cancer patients based on dyspnea, anorexia, Karnofsky performance status score, clinical prediction of survival, total WBC, and lymphocyte percentage. The PaP score assigns patients to three different risk groups according to a 30-day survival probability--group A, >70%; group B, 30%-70%; group C, <30%. The impact of delirium is known but was not incorporated into the PaP score.


MATERIALS AND METHODS
Our aim was to incorporate information on delirium into the PaP score based on a retrospective series of 361 terminally ill cancer patients. We followed the approach of "validation by calibration," proposed by van Houwelingen and later adapted by Miceli for achieving score revision with inclusion of a new variable. The discriminating performance of the scores was estimated using the K statistic.


RESULTS
The prognostic contribution of delirium was confirmed as statistically significant (p < .001) and the variable was accordingly incorporated into the PaP score (D-PaP score). Following this revision, 30-day survival estimates in groups A, B, and C were 83%, 50%, and 9% for the D-PaP score and 87%, 51%, and 16% for the PaP score, respectively. The overall performance of the D-PaP score was better than that of the PaP score.


CONCLUSION
The revision of the PaP score was carried out by modifying the cutoff values used for prognostic grouping without, however, affecting the partial scores of the original tool. The performance of the D-PaP score was better than that of the PaP score and its key feature of simplicity was maintained.
Consumers' purchase intention of organic food in China.

BACKGROUND
The global market for organic food has developed significantly in the past decade. The organic food industry in China is export oriented, with production growing rapidly, although the domestic market remains relatively small. This paper surveys 432 consumers from three cities in China, consequently establishing a logit model to analyse the main factors affecting consumers' choice for organic food.


RESULTS
The result indicates that Chinese consumers' intent to purchase organic food is strongly affected by factors such as income, degree of trust in organic food, degree of acceptance of organic food price, and consumers' concern on self-health. This intent is only slightly affected by factors such as consumers' age, education level and concern about environmental protection.


CONCLUSION
Based on the results, the following measures are recommended: reduce the cost of organic food through multiple channels to cut down the market price; establish and perfect the supervision system of organic food; and promote organic food through various channels.
