Classification of human motion based on affective state descriptors
Cataloged from PDF version of article.Human body movements and postures carry emotion-specific information. On the basis of this motivation, the objective of
this study is to analyze this information in the spatial and temporal structure of the motion capture data and extract features
that are indicative of certain emotions in terms of affective state descriptors. Our contribution comprises identifying the
directly or indirectly related descriptors to emotion classification in human motion and conducting a comprehensive analysis
of these descriptors (features) that fall into three different categories: posture descriptors, dynamic descriptors, and
frequency-based descriptors in order to measure their performance with respect to predicting the affective state of an input
motion. The classification results demonstrate that no single category is sufficient by itself; the best prediction performance
is achieved when all categories are combined. Copyright Š 2013 John Wiley & Sons, Ltd
Steady late quaternary slip rate on the Cinarcik section of the North Anatolian fault near Istanbul, Turkey
The distribution of plate motion between multiple fault strands and how this distribution may evolve remain poorly understood, despite the key implications for seismic hazards. The North Anatolian Fault in northwest Turkey is a prime example of a multistranded continental transform. Here we present the first constraints on late Quaternary slip rates on its northern branch across the Cinarcik Basin in the eastern Marmara Sea. We use both deep penetration and highâresolution multichannel seismic reflection data with a stratigraphic age model to show that a depocenter has persisted near the fault bend responsible for that transform basin. Successively older depocenters have been transported westward by fault motion relative to Eurasia, indicating a uniform rightâlateral slip rate of 18.5âmm/yr over the last 500,000âyears, compared to overall GPS rates (23â24âmm/yr). Thus, the northern branch has slipped at a nearly constant rate and has accounted for most of the relative plate motion between Eurasia and Anatolia since ~0.5âMa
Adverse effects of extra-articular corticosteroid injections: a systematic review
<p>Abstract</p> <p>Background</p> <p>To estimate the occurrence and type of adverse effects after application of an extra-articular (soft tissue) corticosteroid injection.</p> <p>Methods</p> <p>A systematic review of the literature was made based on a PubMed and Embase search covering the period 1956 to January 2010. Case reports were included, as were prospective and retrospective studies that reported adverse events of corticosteroid injection. All clinical trials which used extra-articular corticosteroid injections were examined. We divided the reported adverse events into major (defined as those needing intervention or not disappearing) and minor ones (transient, not requiring intervention).</p> <p>Results</p> <p>The search yielded 87 relevant studies:44 case reports, 37 prospective studies and 6 retrospective studies. The major adverse events included osteomyelitis and protothecosis; one fatal necrotizing fasciitis; cellulitis and ecchymosis; tendon ruptures; atrophy of the plantar fat was described after injecting a neuroma; and local skin effects appeared as atrophy, hypopigmentation or as skin defect. The minor adverse events effects ranged from skin rash to flushing and disturbed menstrual pattern. Increased pain or steroid flare after injection was reported in 19 studies. After extra-articular injection, the incidence of major adverse events ranged from 0-5.8% and that of minor adverse events from 0-81%. It was not feasible to pool the risk for adverse effects due to heterogeneity of study populations and difference in interventions and variance in reporting.</p> <p>Conclusion</p> <p>In this literature review it was difficult to accurately quantify the incidence of adverse effects after extra-articular corticosteroid injection. The reported adverse events were relatively mild, although one fatal reaction was reported.</p

Reevaluation of an old electrocardiographic criterion for coronary disease: TV1 > TV6
Background: Two different studies were conducted to evaluate the value of T wave in V1 taller than T wave in V6 (TV1 > TV6) pattern as an indicator of coronary artery disease. Method: In the first study 5,300 resting ECGs were examined and the criterion was found in 283 patients. All of these patients were examined with echocardiography. In the second study, ECG tracings and coronary angiograms of another 500 patients were evaluated. Results: In the first study, in 59 of 283 patients left ventricular hypertrophy was detected and these patients were excluded from the study. There were ST segment-T wave changes and/or Q wave on ECG suggesting coronary ischemia or myocardial infarction in 160 of the 224 patients. TV1 > TV6 criterion was the sole finding in 64 of the 224 patients. All of the 224 patients underwent coronary angiography and coronary artery disease was detected in 185 patients; 134 of the 160 patients (83.3%) and 51 of 64 patients (80%) had one-vessel or multivessel disease. There was no significant difference among the groups regarding coronary artery disease. Left anterior descending artery was involved in all of the 185 patients. In the second study, 408 patients were found to have coronary disease involvement and 92 patients showed normal or insignificant coronary disease. Sixty-six of the 408 patients with coronary disease and four of 92 patients were found to have the TV1 > TV6 pattern. Sensitivity of the criterion was 16.1%, specificity was 95.6%, and accuracy was 94.2%. Conclusions: According to these results, it is concluded that TV1 > TV6 with or without other ECG findings is a good criterion suggesting coronary artery disease, especially left anterior descending artery involvement in patients without left ventricular hypertrophy
