Processing and Linking Audio Events in Large Multimedia Archives: The EU inEvent Project

In the inEvent EU project [1], we aim at structuring, retrieving, and sharing large archives of networked, and dynamically changing, multimedia recordings, mainly consisting of meetings, videoconferences, and lectures. More specifically, we are developing an integrated system that performs audiovisual processing of multimedia recordings, and labels them in terms of interconnected “hyper-events” (a notion inspired from hyper-texts). Each hyper-event is composed of simpler facets, including audio-video recordings and metadata, which are then easier to search, retrieve and share. In the present paper, we mainly cover the audio processing aspects of the system, including speech recognition, speaker diarization and linking (across recordings), the use of these features for hyper-event indexing and recommendation, and the search portal. We present initial results for feature extraction from lecture recordings using the TED talks. Index Terms: Networked multimedia events; audio processing: speech recognition; speaker diarization and linking; multimedia indexing and searching; hyper-events.
Intertrochanteric versus supracondylar osteotomy for severe femoral anteversion.

Severe femoral anteversion may require operative correction if it results in cosmetic or functional disability. Complication rates < or = 15% have been reported after derotational osteotomy. We report the results of 51 osteotomies in 27 patients with idiopathic femoral anteversion over a 15-year period at a major pediatric orthopaedic referral center. Thirty-four derotational osteotomies in 17 patients were performed using a supracondylar technique with crossed-pin fixation. There was a 14.7% complication rate. Sixteen osteotomies in 10 patients were performed using an intertrochanteric osteotomy and blade-plate fixation with the patient in the prone position; there were no reported complications. The intertrochanteric osteotomy allowed more accurate correction of the intoeing deformity and decreased the need for postoperative immobilization. In addition, the more secure blade-plate fixation benefits the active child > 8 years of age who requires operative correction of severe femoral anteversion.
Torsion of young hearts: a speckle tracking study of normal infants, children, and adolescents.

AIM Our aim was to study the rotational mechanics of the heart in a special population including neonates, young children, and adolescents. We showed the effect of age on torsion and the different rotational variables. This study is the first that focuses on neonatal heart mechanics. METHODS AND RESULTS We recruited 70 normal children between few hours and 18 years old. We excluded abnormal rhythm and function. Short-axis parasternal views were taken at the base of the heart and the apex. Using the speckle tracking technique, we analysed the rotation curves at apex and base and calculated the net twist and torsion of the left ventricle (LV). We also calculated the twist and untwist rates to get the correlation with age and body surface area (BSA). Rotational patterns during diastole also were studied. Deformational time delay between the base and the apex was looked up. Apical rotation and net twist increased with age significantly (r = 0.41 and 0.38, respectively, P = 0.001) but when normalized by LV length there was fixed torsion among age groups. Rotation velocity declined with ageing during systole and diastole for both base and apex (r = -0.58 and -0.62 for twist rate, -0.69 and -0.6 for untwist rate, respectively, P < 0.001). Concordant results were reported for BSA. Deformational delay was decreasing with age (r = -0.74 for systolic and -0.53 for diastolic, P < 0.001). CONCLUSION Infants hearts tend to deform more and faster than other groups. While apical twist and net twist increase with age, torsion is fixed among age groups. In young hearts, torsion is the result of differential twist.
PROCEEDINGS of the Seventh International Driving Symposium on Human Factors in Driver Assessment , Training , and Vehicle Design USING MANUAL MEASUREMENTS ON EVENT RECORDER VIDEO AND IMAGE PROCESSING ALGORITHMS TO EXTRACT OPTICAL PARAMETERS AND RANGE

Vehicle kinematics and optical parameters such as optical angle, optical expansion rate, and tau are thought to underlie drivers’ ability to avoid and handle critical traffic situations. Analyses of these parameters in naturalistic driving data with video, such as commercial event recordings of near-crashes and crashes, can provide insight into driver behavior in critical traffic situations. This paper describes a pair of methods, one for the range to a lead vehicle and one for its optical angle, that are derived from image processing mathematics and that provide driver behavior researchers with a relatively simple way to extract optical parameters from video-based naturalistic data when automatic image processing is not possible. The methods begin with manual measurements of the size of other road users on a video on a screen. To develop the methods, 20 participants manually measured the width of a lead vehicle on 14 images where the lead vehicle was placed at different distances from the camera. An on-market DriveCam Event Recorder was used to capture these images. A linear model that corrects distortion and modeling optics was developed to transform the on-screen measurements distance (range) to and optical angle of the vehicle. The width of the confidence interval for predicted range is less than 0.1m when the actual distance is less than 10m and the lead-vehicle width estimate is correct. The methods enable driver behavior researchers to easily and accurately estimate useful kinematic and optical parameters from videos (e.g., of crashes and nearcrashes) in event-based naturalistic driving data.
Hydrodynamic resistance and flow patterns in the gills of a tilapine fish

SUMMARY The gills of teleost fishes are often discussed as an archetypal counter-current exchange system, capable of supporting the relatively high metabolic rates of some fishes despite the low oxygen solubility of water. Despite an appreciation for the physiology of exchange at the gills, many questions remain regarding the hydrodynamical basis of ventilation in teleost fishes. In this study, the hydrodynamic resistance and flow fields around the isolated gills of a tilapia, Oreochromis mossambicus, were measured as a function of the applied pressure head. At ventilatory pressures typical of a fish at rest, the hydrodynamic resistance of the gills was nearly constant, the flow was laminar, shunting of water around the gills was essentially absent, and the distribution of water flow was relatively uniform. However, at the higher pressures typical of an active or stressed fish, some of these qualities were lost. In particular, at elevated pressures there was a decrease in the hydrodynamic resistance of the gills and substantial shunting of water around the gills. These effects suggest mechanical limits to maximum aerobic performance during activity or under adverse environmental conditions.
Long-Term Outcome of Aortic Dissection With Patent False Lumen: Predictive Role of Entry Tear Size and Location

Background— Patent false lumen in aortic dissection has been associated with poor prognosis. We aimed to assess the natural evolution of this condition and predictive factors. Methods and Results— One hundred eighty-four consecutive patients, 108 surgically treated type A and 76 medically treated type B, were discharged after an acute aortic dissection with patent false lumen. Transesophageal echocardiography was performed before discharge, and computed tomography was performed at 3 months and yearly thereafter. Median follow-up was 6.42 years (quartile 1 to quartile 3: 3.31–10.49). Forty-nine patients died during follow-up (22 type A, 27 type B), 31 suddenly. Surgical or endovascular treatment was indicated in 10 type A and 25 type B cases. Survival free from sudden death and surgical-endovascular treatment was 0.90, 0.81, and 0.46 (95% CI, 0.36–0.55) at 3, 5, and 10 years, respectively. Multivariate analysis identified baseline maximum descending aorta diameter (hazard ratio [HR]: 1.32 [1.10–1.59]; P=0.003), proximal location (HR: 1.84 [1.06–3.19]; P=0.03), and entry tear size (HR: 1.13 [1.08–1.2]; P<0.001) as predictors of dissection-related adverse events, whereas mortality was predicted by baseline maximum descending aorta diameter (HR: 1.36 [1.08–1.70]; P=0.008), entry tear size (HR: 1.1 [1.04–1.16]; P=0.001), and Marfan syndrome (HR: 3.66 [1.65–8.13]; P=0.001). Conclusions— Aortic dissection with persistent patent false lumen carries a high risk of complications. In addition to Marfan syndrome and aorta diameter, a large entry tear located in the proximal part of the dissection identifies a high-risk subgroup of patients who may benefit from earlier and more aggressive therapy.
Together We Can: Bilingual Bootstrapping for WSD

Recent work on bilingual Word Sense Disambiguation (WSD) has shown that a resource deprived language (L1) can benefit from the annotation work done in a resource rich language (L2) via parameter projection. However, this method assumes the presence of sufficient annotated data in one resource rich language which may not always be possible. Instead, we focus on the situation where there are two resource deprived languages, both having a very small amount of seed annotated data and a large amount of untagged data. We then use bilingual bootstrapping, wherein, a model trained using the seed annotated data of L1 is used to annotate the untagged data of L2 and vice versa using parameter projection. The untagged instances of L1 and L2 which get annotated with high confidence are then added to the seed data of the respective languages and the above process is repeated. Our experiments show that such a bilingual bootstrapping algorithm when evaluated on two different domains with small seed sizes using Hindi (L1) and Marathi (L2) as the language pair performs better than monolingual bootstrapping and significantly reduces annotation cost.
Effect of dietary nitrogen source on carbohydrate metabolism in the rumen of the young steer

1. Steers, fitted with simple rumen and duodenal cannulas, were given diets of approximately equal parts of flaked maize and hay (A) (containing 16 g nitrogen/kg dry matter (dm)) or diets of flaked maize and straw supplemented with decorticated groundnut meal (B), fish meal (C), or heated (D) or unheated (E) soya-bean meal (containing 24 g N/kg dm). Chromic oxide was given as a marker with the feeds, and flows of different combined sugars at the duo denum estimated from the values for sugars: marker at this site. Contributions of bacterial constituents to these flows were estimated from amounts of RNA present. 2. Rumen bacteria from steers receiving diet A contained approximately 110 g α-dextran-glucose/kg dm and contributed about 60 g α-dextran-glucose/d at the duodenum; bacteria from steers receiving diets B, C, D or E contained 25–40 g α-dextran-glucose/kg dm and contributed about 20–30 g α-dextran-glucose/d at the duodenum. There were no significant differences between different N supplements. About half the α-dextran-glucose, varying amounts of the mannose and galactose, and nearly all the rhamnose and ribose in duodenal digesta were contributed by the bacteria. Almost all the arabinose, xylose and cellulose-glucose was of dietary origin. 3. For steers receiving diet A, mean coefficients of digestibility between mouth and duodenum, corrected where necessary for bacterial contribution, were 0.96, 0.73, 0.58, 0.22 and 0.53 for starch-glucose, galactose, arabinose, xylose and cellulose-glucose respectively. Corresponding mean values when diets B, C, D and E were given, which did not differ significantly amongst themselves, were 0.98, 0.79, 0.81, 0.59 and 0.58. Most values for galactose, arabinose and xylose were significantly higher than the diet A values.
MMP2 and MMP9 associate with crescentic glomerulonephritis

Abstract Background: Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by multiple organ involvement. Lupus nephritis (LN) is a common manifestation with a wide variety of histological appearances. Matrix metalloproteinases (MMP) 2 and 9 are gelatinases capable of degrading glomerular basement membrane type IV collagen, which have been associated with LN. We examine the expression of MMP2 and MMP9 in different classes of LN. Methods: MMP2 and MMP9 expression was detected by immunohistochemistry in sections from renal biopsy specimens with class III, class IV and class V LN (total n = 31), crescentic immunoglobulin A nephropathy (n = 6), pauci-immune glomerulonephritis (n = 7), minimal change disease (n = 2), mesangiocapillary glomerulonephritis (n = 7), diabetic nephropathy (n = 12) and histologically normal controls (n = 8). Results: MMP2 and MMP9 were not expressed in all classes of LN, but were observed in LN with cellular and fibrocellular crescents. MMP2/MMP9 was expressed in cellular and fibrocellular crescents regardless of glomerulonephritis but not observed in inactive fibrous crescents or with mesangial proliferation. This suggests that MMP2 and MMP9 are involved in the development of extracapillary proliferative lesions. Conclusions: MMP2/MMP9 is expressed with active extracapillary proliferation. Further study is necessary to define whether the expression of MMP2/MMP9 reflects a role in glomerular repair after injury, a role in organ-level immune responses or a role as a marker of epithelialization.
High detection rate of circulating tumor cells in blood of patients with prostate cancer using telomerase activity.

BACKGROUND Circulating tumor cells (CTCs) cannot be readily detected with currently available methods in the majority of patients with prostate cancer. Telomerase activation, one of the major immortalization events, is found in most cases of prostate cancer. We attempted to develop a method using telomerase activity to isolate CTCs in patients with prostate cancer. PATIENTS AND METHODS Peripheral blood mononuclear cells (PBMCs) were isolated from whole blood using Ficoll-Hypaque. Immunomagnetic beads coated with an epithelial cell-specific antigen antibody (BerEP4) were used to harvest epithelial cells from PBMCs. Telomerase activity was detected in harvested epithelial cells using the telomerase-PCR-enzyme-linked immunosorbent assay method. RESULTS Blood samples from 107 patients with prostate cancer were studied. CTCs were detected in 19 of 24 (79%) patients with advanced prostate cancer. In contrast, CTCs were not detected in blood samples from 22 healthy male volunteers. CTCs were even identified in patients with an undetectable (<0.1 ng/ml) serum prostate-specific antigen (PSA). CTCs were detected in 55 of 70 (79%) patients with localized prostate cancer before radical prostatectomy (n = 30) or brachytherapy (n = 40). CTCs were also detected in 3 of 13 patients (23%) with an undetectable serum PSA measured at least 1 year after radical prostatectomy, which is consistent with the expected relapse rate in this setting. CONCLUSION CTCs can be detected using telomerase activity in a large majority and a wide variety of patients with prostate cancer, including those with localized disease.
Continuous Toxicity Monitoring in Phase II Trials in Oncology

Summary The goal of a phase II trial in oncology is to evaluate the efficacy of a new therapy. The dose investigated in a phase II trial is usually an estimate of a maximum‐tolerated dose obtained in a preceding phase I trial. Because this estimate is imprecise, stopping rules for toxicity are used in many phase II trials. We give recommendations on how to construct stopping rules to monitor toxicity continuously. A table is provided from which Pocock stopping boundaries can be easily obtained for a range of toxicity rates and sample sizes. Estimation of the probability of toxicity and response is also discussed.
Ultrathin high-K gate stacks for advanced CMOS devices

Reviews recent progress in and outlines the issues for high-K high-temperature (/spl sim/1000/spl deg/C) poly-Si CMOS processes and devices and also demonstrate possible solutions. Specifically, we discuss device characteristics such as gate leakage currents, flatband voltage shifts, charge trapping, channel mobility, as well as integration and processing aspects. Results on a variety of high-K candidates including HfO/sub 2/, Al/sub 2/O/sub 3/, HfO/sub 2//Al/sub 2/O/sub 3/, ZrO/sub 2/, silicates, and AlN/sub y/(O/sub x/) deposited on silicon by different deposition techniques are shown to illustrate the complex issues for high-K dielectric integration into current Si technology.
Vegetation Response and Landscape Dynamics of Indian Summer Monsoon Variations during Holocene: An Eco-Geomorphological Appraisal of Tropical Evergreen Forest Subfossil Logs

The high rainfall and low sea level during Early Holocene had a significant impact on the development and sustenance of dense forest and swamp-marsh cover along the southwest coast of India. This heavy rainfall flooded the coastal plains, forest flourishing in the abandoned river channels and other low-lying areas in midland.The coastline and other areas in lowland of southwestern India supply sufficient evidence of tree trunks of wet evergreen forests getting buried during the Holocene period under varying thickness of clay, silty-clay and even in sand sequences. This preserved subfossil log assemblage forms an excellent proxy for eco-geomorphological and palaeoclimate appraisal reported hitherto from Indian subcontinent, and complements the available palynological data. The bulk of the subfossil logs and partially carbonized wood remains have yielded age prior to the Holocene transgression of 6.5 k yrs BP, suggesting therein that flooding due to heavy rainfall drowned the forest cover, even extending to parts of the present shelf. These preserved logs represent a unique palaeoenvironmental database as they contain observable cellular structure. Some of them can even be compared to modern analogues. As these woods belong to the Late Pleistocene and Holocene, they form a valuable source of climate data that alleviates the lack of contemporaneous meteorological records. These palaeoforests along with pollen proxies depict the warmer environment in this region, which is consistent with a Mid Holocene Thermal Maximum often referred to as Holocene Climate Optimum. Thus, the subfossil logs of tropical evergreen forests constitute new indices of Asian palaeomonsoon, while their occurrence and preservation are attributed to eco-geomorphology and hydrological regimes associated with the intensified Asian Summer Monsoon, as recorded elsewhere.
A Continuous-Exchange Cell-Free Protein Synthesis System Based on Extracts from Cultured Insect Cells

In this study, we present a novel technique for the synthesis of complex prokaryotic and eukaryotic proteins by using a continuous-exchange cell-free (CECF) protein synthesis system based on extracts from cultured insect cells. Our approach consists of two basic elements: First, protein synthesis is performed in insect cell lysates which harbor endogenous microsomal vesicles, enabling a translocation of de novo synthesized target proteins into the lumen of the insect vesicles or, in the case of membrane proteins, their embedding into a natural membrane scaffold. Second, cell-free reactions are performed in a two chamber dialysis device for 48 h. The combination of the eukaryotic cell-free translation system based on insect cell extracts and the CECF translation system results in significantly prolonged reaction life times and increased protein yields compared to conventional batch reactions. In this context, we demonstrate the synthesis of various representative model proteins, among them cytosolic proteins, pharmacological relevant membrane proteins and glycosylated proteins in an endotoxin-free environment. Furthermore, the cell-free system used in this study is well-suited for the synthesis of biologically active tissue-type-plasminogen activator, a complex eukaryotic protein harboring multiple disulfide bonds.
Using genetic algorithm for Persian grammar induction

Most of efficient computational approaches in NLP tasks are supervised methods which need annotated corpora. But the lack of supervised data in Persian encourages researchers to increase their interests and efforts on unsuper-vised and semi-supervised approaches. This paper presents a novel semi-supervised approach which called Genetic-based inside-outside (GIO), for Persian grammar inference for inducing a grammar model in a PCFG formalism. GIO is an extension of the inside-outside algorithm enriched by some notions of genetic algorithm. In pure genetic algorithm for grammar induction, randomly generated initial population make it computationally expensive, so we used inside-outside algorithm to generate initial population. Our experiments show that our approach's result is better than other applied methods for Persian grammar induction.
Comparative Study of Nutritional Status and Dietary Habits of Children from Public and Private Primary Schools in Zagazig City, Egypt

The future of the society depends on the quality of life of the children. The nutritional status of school aged children impacts their health, cognition and subsequently their educational achievement. The present study was conducted to determine the nutritional status and dietary habits of school aged children (6-12 years) attending public (non-fee paying-NFP) and private (fee paying-FP) primary schools in Zagazig city; capital of Sharqia governorate, Egypt. Based on the World Health Organization (WHO) standard mean of Body Mass Index (BMI), obesity and overweight constituted higher percentage among students in the private school than in the public school, while underweight was high among students in the public school (18.7%) compared to students in private school (7.5%). More than half of the public school students (52.7%) complaining of short stature compared to 27.4% of the private school students. A statistically significant difference between the two studied groups regarding taking lunch meal (P-value = 0.03) and the students' preference of eating fried food (P-value = 0.00) were detected. In conclusion, there were statistically significant differences between the two studied groups regarding their Body Mass Index and daily food consumption.
Effect of Cognitive Processing Therapy and Holographic Reprocessing on Reduction of Posttraumatic Cognitions in Students Exposed to Trauma

Objective This research was conducted to examine the effect of cognitive processing therapy and holographic reprocessing on the reduction of posttraumatic cognitions in students exposed to trauma. Method This was an experimental study with spread pretest-posttest randomized groups design. Statistical society of this research consisted of male freshman, junior and senior high school students of Uremia (N=10286). Utilizing Traumatic Events Screening Inventory, and SCL-90 R on 1000 randomly selected high school students, 129 students were recognized as having experienced traumatic events. Of the subjects, 60 were selected randomly. Then, clinical interview was conducted, and the selected sample was randomly assigned in to three groups of cognitive processing therapy, holographic reprocessing and control. These groups responded to Posttraumatic Cognitions Inventory in pretest and post test. Differences of pre-post test scores were analyzed using one way ANOVA and Scheffe test. Results The results demonstrated significant differences between the three groups in total score of the Posttraumatic Cognition Inventory. Difference was also observed in negative cognitions on self and self-blame dimensions. Furthermore, these two therapeutic methods were equally effective in the reduction of posttraumatic cognitions. Conclusion It appears that cognitive processing therapy and holographic reprocessing which had been originally developed and tested for sexually assaulted females, can also be applied for the victims of other traumatic events, particularly adolescents.
