A Multifractal Based Dynamic Bandwidth Allocation Approach for Network Traffic Flows

In this paper, we evaluate a new dynamic bandwidth allocation approach for multifractal traffic arrivals. For this end, first of all we derive an analytical expression for estimating byte loss probability at a single server queue based on the second order statistics for multifractal traffic processes. In order to make the estimation procedure numerically tractable without losing the accuracy, we assume and demonstrate that an exponential model is adequate for representing the variance of traffic processes under different time scale aggregation. Extensive experimental tests validate the efficiency and accuracy of the proposed loss probability estimation approach, its superior performance for admission control and link resource allocation applications with respect to some well-known approaches suggested in the literature.

Psychopathology in Offspring of Mothers with Borderline Personality Disorder: A Pilot Study

Objective: Children of mothers with borderline personality disorder (BPD) were hypothesized to be at greater risk for psychopathology, particularly impulse spectrum disorders, than children of mothers with other personality disorders. Method: Twenty-one index children were compared with 23 children of mothers with a nonborderline personality disorder. Diagnoses were obtained using the Kiddie Schedule for Affective Disorders and Schizophrenia–Episodic Version (KSADS-E) and the Child Diagnostic Interview for BPD (CDIB), and functioning was rated with the Child Global Assessment Schedule (CGAS). Physical, sexual, and verbal abuse, as well as family violence and placements, were also assessed. Results: The children of the borderline mothers, as compared with controls, had more psychiatric diagnoses, more impulse control disorders, a higher frequency of child BPD, and lower CGAS scores. There were no differences between the groups for trauma. Conclusion: The offspring of borderline mothers are at high risk for psychopathology.
The structure and development of cranial and facial sutures.

It is surprising, in view of the controversy which has long raged about the functional role of the sutures in the growth of the skull, that so little attention has been paid to their histological structure and development. The most comprehensive study is that of Sitsen (1933), who describes the development of the lambdoid suture in man between the 8th month of foetal life and 12 years. Mair (1926), Petersen (1930), Troitsky (1932), Bernstein (1933), Weinman & Sicher (1947), Moss (1954), and Scott (1954) have made more limited contributions to the literature. As it was evident that much more detailed and accurate information was required in order to provide the necessary basis for experimental work on the morphogenesis and functions of the sutures, it was decided to investigate the development and structure of a variety of sutures in available foetal, young and adult material.
The guard-ring termination for the high-voltage SiC Schottky barrier diodes

In this report, we propose the guard-ring structure as the edge termination for the high-voltage SiC Schottky barrier diodes. The local oxidation process is used to form the mesa of a p-n junction as the guard-ring. The comparison between the Al/Ti Schottky barrier diodes with and without the guard-ring indicates the effectiveness of the guard-ring to relax the electric field, from the results that the breakdown voltage is about two times larger with high yield. <<ETX>>
Immediate definitive rehabilitation of the edentulous patient using an intraorally welded titanium framework: a 3-year prospective study.

OBJECTIVE The aim of this prospective study was to evaluate the concept of intraoral welding as a suitable technique for the placement of a final restoration in the edentulous patient on the same day as surgery. METHOD AND MATERIALS Any patient with a completely edentulous arch who was considered eligible received a fixed restoration supported by an intraorally welded titanium bar. Definitive abutments were connected to the implants and then welded to a titanium bar using an intraoral welding unit. This framework was used to support the definitive acrylic restoration, which was fitted on the same day as implant placement. Restoration and implant success, mean marginal bone loss, pocket probing depth, and bleeding on probing were assessed over a 36-month follow-up period. RESULTS Twenty-six patients with an edentulous maxilla and 34 patients with an edentulous mandible, with a mean age of 57.1 years (SD = 17.9, n = 60), were consecutively treated with 324 immediately loaded implants. No fractures or radiographically detectable alteration of the welded framework was evident. A total of 321 (99.1%) implants osseointegrated and were clinically stable at the 6-month follow-up. At the 36-month follow-up, the accumulated mean marginal bone loss was, respectively, 0.967 mm (SD = 0.361) for the maxillary cases and 1.016 mm (SD = 0.413) for the mandibular cases. CONCLUSIONS It is possible on the same day of surgery to successfully rehabilitate the edentulous patient with a fixed definitive prosthesis supported by an intraorally welded titanium framework.
Suicide trends in discharged patients with mood disorders: associations with selective serotonin uptake inhibitors and comorbid substance misuse

We determined the rates of suicide in two consecutive time intervals of low and high selective serotonin reuptake inhibitor (SSRI) prescribing for men and women with mood disorders, who were at relatively high risk of suicide, in a discharged hospitalized sample. High quality Swedish national registers were cross-linked to estimate rates of suicide. The results were stratified by three age-bands, and rates of comorbid substance misuse were explored. These were compared with general population suicide rates. There were 1606 suicides in discharged patients with mood disorders. Suicide rates decreased for all women during 1989–94 and 1995–2000 [odds ratio (OR)=0.74, 95% confidence interval (CI)=0.64–0.85] and a trend was found towards lower rates in men (OR=0.89, 95% CI=0.78–1.02). Approximately 90% of suicides occurred in those aged over 40 years; thus, the inpatient sample lacked the power to discriminate clear effects in the younger age groups. There was no increase or decrease in the rates of substance use disorders in patients who committed suicide. There were 20 851 suicides in the general population during 1989–2000. Suicide rates were lower at all ages for men and women in the general population in the interval of high SSRI prescribing. We conclude that there is no evidence from this study of an increase in suicide rates following the introduction of SSRIs in the general population or in a high-risk inpatient sample.
EFFECTS OF PROPRIOCEPTIVE TRAINING ON BALANCE SKILLS AMONG SPORT DANCE DANCERS

The aim of this research is to determine effects of proprioceptive training on the improvement of balance skills among sport dance dancers. Proprioceptive training is realized throughout tasks that included the establishing and maintenance of various positions on balance boards of different dimensions, working surfaces and the size of the backbone. In this study, 38 sport dance competitors participated, both male and female, divided into an experimental and control group. The experimental group took part in a proprioceptive training program over a period of 12 weeks (3 x 30 minutes per week). The control group (at the same time as the experimental) had regular sport dance training. At the beginning and at the end of the experiment, balance skills were measured by means of 7 different balance tests: the one-leg balance, two-leg balance, balancing with open or closed eyes. Basic descriptive statistics were calculated for all of the results. The effects of the applied proprioceptive model were determined using a multivariate (MANCOVA) and univariate (ANCOVA) analysis of covariance. Statistically significant differences among the groups in the final measurement (p=.00) show a positive effect of the applied proprioceptive training program on the development of balance skills with the experimental group, in all the tests. Therefore, the use of a proprioceptive training model, as an innovative approach in individual and group fitness dance training, is recommended.
A method for sea ice thickness and concentration analysis based on SAR data and a thermodynamic model

An analysis of ice thickness distribution is a challenge, particularly in a seasonal sea ice zone with a strongly dynamic ice motion field, such as the Gulf of St. Lawrence off Canada. We present a novel automated method for ice concentration and thickness analysis combining modeling of sea ice thermodynamics and detection of ice motion on the basis of space-borne Synthetic Aperture Radar (SAR) data. Thermodynamic evolution of sea ice thickness in the Gulf of St. Lawrence was simulated for two winters, 2002–2003 and 2008–2009. The basin-scale ice thickness was controlled by atmospheric forcing, but the spatial distribution of ice thickness and concentration could not be explained by thermodynamics only. SAR data were applied to detect ice motion and ice surface structure during these two winters. The SAR analysis is based on estimation of ice motion between SAR image pairs and analysis of the local SAR texture statistics. Including SAR data analysis brought a significant added value to the results based on thermodynamics only. Our novel method combining the thermodynamic modeling and SAR yielded results that well match with the distribution of observations based on airborne Electromagnetic Induction (EM) method. Compared to the present operational method of producing ice charts for the Gulf of St. Lawrence, which is based on visual interpretation of SAR data, the new method reveals much more detailed and physically based information on spatial distribution of ice thickness. The algorithms can be run automatically, and the final products can then be used by ice analysts for operational ice service. The method is globally applicable to all seas where SAR data are available.
Management of Scorpion Envenomation in Children

*1 Post Graduate in Pediatrics in RMMCH, Chidambaram 2 Associate Professor in Department of Pediatrics, RMMCH, Chidambaram 3 Senior Resident in Department of Pediatrics, RMMCH, Chidambaram 4 Senior Resident in Cardiology, Department of Medicine, RMMCH, Chidambaram ABSTRACT Introduction: The study was aimed to describe our experience with epidemiological characteristics, management options, and outcome of scorpion envenomation in children. Materials and Methods: This prospective study was conducted at Rajah Muthiah Medical College and Hospital. The epidemiologic details including geographical locality of the event, age distribution, gender, and sting sites were noted in all hospitalized children with scorpion bite injury. Results: During the study period, a total 100 children were managed for scorpion sting. Male children were commoner victims of scorpion sting. Scorpion sting had bimodal pattern. Prazosin was used in 89 children. Conclusion: In this study, there was bimodal distribution of the scorpion sting cases, male children were more affected, and almost all of them improved with good outcome. We did not use anti-venin in the present study. The data from the study will serve not only to create heightened public awareness about scorpion envenomation but also to develop public awareness strategies and preventive measures.
Warfarin versus aspirin in the elderly in primary prophylaxis for atrial fibrillation

the incidence of HIV/AIDS in adults (15–49 years) is between 6.4% and 11.9% [5]. Africa, like Europe, has an ageing population but with a biphasic age distribution, the old and the young. The strong and economically active have been removed in large numbers by HIV/AIDS. The elderly are thus economically and socially important in these societies and yet treatments for the neurodegenerative diseases they are inevitably going to suffer are out of reach economically. Dotchin and co-workers’ paper, however, does remind us of the opportunities that exist in Africa for our understanding of Parkinson’s disease. Some of the rural communities are stable over long periods of time and in Tanzania 62.5% of the population live in rural areas [6]: there are fewer pollutants and potentially less compounding variables in terms of understanding the epidemiology of Parkinson’s disease. We have learnt much about the nature and causation of the disease by examining populations in which disease prevalence is very different from the western world, and there is an urgent need to study Parkinson’s disease and other degenerative disorders in these populations. A more urgent need however is to address the humanitarian aspects of an untreated but treatable disease, which is often forgotten in the context of overwhelming numbers of infectious disorders. The effects of medical migration that have resulted in many African doctors emigrating to wealthier countries such as the United Kingdom [7], results in the grossly inadequate number of neurologists and the virtual absence of geriatricians. This issue affects specialists [8] from many countries, and needs to be urgently addressed by the western world.

Computer Modeling of the Effects of Chewing Sugar-free and Sucrose-containing Gums on the pH Changes in Dental Plaque Associated with a Cariogenic Challenge at Different Intra-oral Sites

Variation in salivary access to different intra-oral sites is an important factor in the site-dependence of dental caries. This study explored, theoretically, how access is modified by chewing sugar-free and sugar-containing gums. A finite difference computer model, described elsewhere, was used. This allowed for diffusion and/or reaction of substrate, acid product, salivary buffers, and fixed-acid groups. Site-dependent saliva/plaque exchange was modeled in terms of a 100-μm-thick salivary film covering the plaque (a) flowing directly from the salivary ducts, (b) flowing from the intra-oral salivary pool, or (c) exchanging with the pool. Computed flow-velocities or rates of exchange were based on previous intra-oral measurements. The model was also tested against an in vitro study conducted by two of the authors. In addition, the three proposed models of saliva/plaque interaction were compared, and the effect of salivary film thickness investigate. Results suggested that: (1) although sugar-free gum chewed during a cariogenic challenge causes a rapid rise in plaque pH, sucrose-containing gums cause the pH, after a temporary rise resulting from increased salivary flow, to stay low for an extended period; (2) the computer model reproduced in vitro tests reasonably well; (3) although the three models of the plaque/saliva interaction start from different assumptions, two lead to closely related predictions; and (4) increasing the assumed salivary film thickness by a large amount (e.g., from 50 to 200 μm) caused no change in modeled Stephan curves, as long as these changes were accompanied by appropriate reductions in film velocity, in accord, theoretically, with the practical clearance data.
Is Word Recognition Automatic? A Cognitive-Anatomical Approach

What are the implications of anatomical localization of component mental operations for cognitive models? In this paper we use the anatomical localizations of visual and auditory word processing that were previously reported from PET studies (Petersen, Fox, Posner, Mintun & Raichle, 1988. We hypothesize that two operations performed simultaneously by the same or heavily interconnected anatomical areas will produce specific interference. One task is repeating back (shadowing) auditory words as quickly as possible. This task is shown to interfere with shifts of visual attention in the direction of peripheral cues. Both tasks are known to require common attentional operations localized to the medial frontal lobe. The shadowing task does not interfere with operations involving priming of a visual word form. This kind of priming involves areas of the ventral occipital lobe not used during shadowing. Finally, both shadowing and semantic priming involve anterior semantic and intentional areas. Accordingly, they can interfere. The conditions under which they produce interference suggest that the interference involves operations performed by the anterior attention system. These experiments support the idea that words automatically activate visual word forms, but involve shared attentional systems for higher level processes.
How did this snail get here? Several dispersal vectors inferred for an aquatic invasive species

SUMMARY 1. How species reach and persist in isolated habitats remains an open question in many cases, especially for rapidly spreading invasive species. This is particularly true for temporary freshwater ponds, which can be remote and may dry out annually, but may still harbour high biodiversity. Persistence in such habitats depends on recurrent colonisation or species survival capacity, and ponds therefore provide an ideal system to investigate dispersal and connectivity. 2. Here, we test the hypothesis that the wide distributions and invasive potential of aquatic snails is due to their ability to exploit several dispersal vectors in different landscapes. We explored the population structure of Physa acuta (recent synonyms: Haitia acuta, Physella acuta, Pulmonata: Gastropoda), an invasive aquatic snail originating from North America, but established in
Gradient Episodic Memory for Continual Learning

One major obstacle towards AI is the poor ability of models to solve new problems quicker, and without forgetting previously acquired knowledge. To better understand this issue, we study the problem of continual learning, where the model observes, once and one by one, examples concerning a sequence of tasks. First, we propose a set of metrics to evaluate models learning over a continuum of data. These metrics characterize models not only by their test accuracy, but also in terms of their ability to transfer knowledge across tasks. Second, we propose a model for continual learning, called Gradient Episodic Memory (GEM) that alleviates forgetting, while allowing beneficial transfer of knowledge to previous tasks. Our experiments on variants of the MNIST and CIFAR-100 datasets demonstrate the strong performance of GEM when compared to the state-of-the-art.
Delineation of an interstitial 9q22 deletion in basal cell nevus syndrome

Basal cell nevus syndrome (Gorlin syndrome) is an autosomal dominant disorder characterized by the presence of multiple basal cell carcinomas (BCC), odontogenic keratocysts, palmoplantar pits, and calcification in the falx cerebri caused by mutational inactivation of the PTCH gene. In few cases, the syndrome is due to a microdeletion at 9q22. Using high‐resolution chromosome analysis we have identified a patient with the karyotype, 46,XY,del(9)(q21.3q31) de novo. He had typical clinical features consistent with basal cell nevus syndrome, but also additional features likely to be caused by loss of additional chromosomal material in this region. The deletion breakpoints were characterized with fluorescence in situ hybridization (FISH) analysis using BAC clones. The 15 Mb long deletion includes 87 RefSeq genes including PTCH. Hemizygosity of one or more genes might contribute to the additional symptoms observed in this patient. © 2004 Wiley‐Liss, Inc.
