Afasia logopénica: presentación de un caso y revisión de la literatura Logopenic Aphasia: a case report an review of the literature

With the progressive aging of the Chilean population the diagnosis of neurodegenerative disorders is increasingly common, and among them is Primary Progressive Aphasia (PPA), with specific symptoms but late consultation. PPA is a clinical syndrome characterized by the degeneration of language regions in the dominant hemisphere that determines an insidious and progressive loss of language. Two types of PPA were recognized: Progressive non-fluent Aphasia (APnF) and Progressive Semantic Aphasia (DS), and was recently identified as a new type, Logopenica Progressive Aphasia (APL). We describe a case evaluated at the University of Chile Clinical Hospital of a woman of 54 years who have a history of 2-3 years of fluent speech with reduced speed due to the difficulty in finding words, had shortcomings in repetition of complex words, phrases and sentences, presence of phonemic paraphasias and impaired episodic memory. What in the phonological assessment supports a diagnosis of APL. Despite the above, the neurological examination was normal. The APL has been associated with Alzheimer’s disease because it presents impaired episodic memory and the neuropathological changes most frequently encountered are amyloid plaques and neurofibrillary tangles. Through this article you may learn more about this disease and who to go if you or some colleague have symptoms to receive some guidance.

Network attributes and phenomena that in uence the formation of network deadlocks are identi ed. Ways in which a network's susceptibility to deadlock can be reduced are presented. Advantages and disadvantages of various proposed approaches are highlighted, and practical usage of certain techniques in experimental and commercial systems is also given.
Assessment of gingival health among school children in Sharjah, United Arab Emirates

Objectives: The present study evaluated the gingival condition among school going children in Sharjah, United Arab Emirates and determined its relationship with tooth brushing frequency, diet and dental caries. Materials and Methods: Four hundred and five children participated in the study. There were 232 boys (57%) and 173 (43%) girls. Children were grouped based on age as ≤6 years (n = 84) mean age 4.72 ± 0.50 and >6 years (n = 321) mean age 8.47 ± 1.65. The amount of dental plaque and gingival condition were assessed on the inner and outer surface of six index teeth using Silness and Loe and Loe and Silness criteria. Dental caries status was assessed using WHO 1997 criteria. Dental examination, tooth brushing frequency and 24 h diet chart were recorded by calibrated dentists. Logistic regression analysis was used to determine the predictors of gingivitis. Results: Increase in decayed, missing, and filled teeth values corresponds to increase in plaque index and gingival index scores (P ≤ 0.05). A logistic regression analysis of the predictors of gingivitis showed that males were 2.11 times less likely to have gingivitis compared with females (odds ratio [OR]: 0.47,95% confidence interval [CI]: 0.24-0.93, P = 0.03) and children aged ≤6 years were 3.06 times less likely to have gingivitis than those aged >6 years (OR: 0.33, 95% CI: 0.17-0.62, P = 0.00). Tooth brushing frequency and diet were not significant predictors. Conclusion: Current study clearly demonstrated that female gender and children more than 6 years were more likely to have gingivitis.
The effect of interferon beta-1b treatment on MRI measures of cerebral atrophy in secondary progressive multiple sclerosis. European Study Group on Interferon beta-1b in secondary progressive multiple sclerosis.

The recently completed European trial of interferon beta-1b (IFNbeta-1b) in patients with secondary progressive multiple sclerosis (SP multiple sclerosis) has given an opportunity to assess the impact of treatment on cerebral atrophy using serial MRI. Unenhanced T(1)-weighted brain imaging was acquired in a subgroup of 95 patients from five of the European centres; imaging was performed at 6-month intervals from month 0 to month 36. A blinded observer measured cerebral volume on four contiguous 5 mm cerebral hemisphere slices at each time point, using an algorithm with a high level of reproducibility and automation. There was a significant and progressive reduction in cerebral volume in both placebo and treated groups, with a mean reduction of 3.9 and 2.9%, respectively, by month 36 (P = 0.34 between groups). Exploratory subgroup analyses indicated that patients without gadolinium (Gd) enhancement at the baseline had a greater reduction of cerebral volume in the placebo group (mean reduction at month 36: placebo 5.1%, IFNbeta-1b 1.8%, P < 0.05) whereas those with Gd-enhancing lesions showed a trend to greater reduction of cerebral volume if the patient was on IFNbeta-1b (placebo 2.6%, IFNbeta-1b 3.7%; P > 0.05). These results are consistent with ongoing tissue loss in both arms of this study of secondary progressive multiple sclerosis. This finding is concordant with previous observations that disease progression, although delayed, is not halted by IFNbeta. The different pattern seen in patients with and without baseline gadolinium enhancement suggests that part of the cerebral volume reduction observed in IFNbeta-treated patients may be due to the anti-inflammatory/antioedematous effect of the drug. Longer periods of observation and larger groups of patients may be needed to detect the effects of treatment on cerebral atrophy in this population of patients with advanced disease.

The MTSA Program Analysis System Whitepaper: July 22, 2008

In current voice telephony, CATV, and wireless networks, traffic is channelized for both access and transport. This channelization is wasteful of resources where multiple services have varying demands for bandwidth and holding times, or a service generates traffic that is bursty in nature. The invention solves these problems by providing flexible and adapatable multiservice access to the networks. Customer requirements are checked by monitoring traffic on a local access at a connection request and/or during the established connection, and the local access is configured according to the transmission requirements. The local access can also be configured in response to the network information.
Statistical LIP modelling for visual speech recognition

We describe a speechreading (lipreading) system purely based on visual features extracted from grey level image sequences of the speaker's lips. Active shape models are used to track the lip contours while visual speech information is extracted from the shape of the contours. The distribution and temporal dependencies of the shape features are modelled by continuous density Hidden Markov Models. Experiments are reported for speaker independent recognition tests of isolated digits. The analysis of individual feature components suggests that speech relevant information is embedded in a low dimensional space and fairly robust to inter- and intra-speaker variability.
How extended work availability affects well-being: The mediating roles of psychological detachment and work-family-conflict

ABSTRACT Studies have identified availability for work during non-work time as a widespread demand that is related to impaired well-being. Whereas existing research results are based on cross-sectional designs, the present study applied a three-wave longitudinal design to improve interpretations of the direction and causation of the effects of extended work availability. In addition, this study investigated mediating processes such as the reduction of psychological detachment and the increase in work-to-family conflict (WFC). A total of 416 people responded to an online survey at three measurement points, with a time lag of 2 months between each survey, to assess the organisational expectations of being available during one’s off-job time as well as psychological detachment, WFC and emotional exhaustion. The results of structural equation modelling indicated that extended work availability is associated with increases in emotional exhaustion over time. A mediation analysis revealed that WFC and psychological detachment mediated this effect. The results of this study provide strong evidence that extended work availability negatively affects employee well-being over time. Furthermore, this study contributes to an explanation of the mediating process of the detrimental effect. This finding can be used for health-related interventions in cases where extended work availability cannot be completely avoided.
MOST satellite photometry of stars in the M67 field: Eclipsing binaries, blue stragglers and δ Scuti variables ⋆

ABSTRACT We present two series of MOST (Microvariability & Oscillations of STars) space-basedphotometry, covering nearly continuously 10 days in 2004 and 30 days in 2007, ofselected variable stars in the upper Main Sequence of the old open cluster M67. Newhigh-precision light curves were obtained for the blue-straggler binary/triple systemsAH Cnc, ES Cnc and EV Cnc. The precision and phase coverage of ES Cnc andEV Cnc is by far superior to any previous observations. The light curve of ES Cncis modelled in detail, assuming two dark photospheric spots and Roche geometry. Ananalysis of the light curve of AH Cnc indicates a low mass ratio (q ∼ 0.13) and a highinclinationangleforthissystem.Twonewlong-periodeclipsingbinaries,GSC 814–323and HD 75638 (non-members of M67) were discovered. We also present ground-basedDDO spectroscopy of ES Cnc and of the newly found eclipsing binaries. Especiallyinteresting is HD 75638, a member of a visual binary, which must itself be a triple ora higher-multiplicity system. New light curves of two δ Scuti pulsators, EX Cnc andEW Cnc, have been analyzed leading to detection of 26 and 8 pulsation frequencies ofhigh temporal stability.Key words: stars: close binaries - stars: eclipsing binaries – stars: variable stars
Sparsity-Aware and Noise-Robust Subband Adaptive Filter

—This paper presents a subband adaptive ﬁlter (SAF) for a system identiﬁcation where an impulse response is sparse and disturbed with an impulsive noise. Beneﬁting from the uses of l 1 -norm optimization and l 0 -norm penalty of the weight vector in the cost function, the proposed l 0 -norm sign SAF ( l 0 -SSAF) achieves both robustness against impulsive noise and much improved convergence behavior than the classical adaptive ﬁlters. Simulation results in the system identiﬁcation scenario conﬁrm that the proposed l 0 -norm SSAF is not only more robust but also faster and more accurate than its counterparts in the sparse system identiﬁcation in the presence of impulsive noise.
Book Review: Psicoanalisi Transazionale

experiences and subsequent changes. Dependency on the part ofclients is redefmed as their way ofconnecting with the therapist while also connecting to others and, more importantly, to themselves. The fmal chapter powerfully evokes a sense of ending and closure for both the therapeutic relationship and the book by looking at how changes within the therapeutic relationship transpose themselves onto other relationships within the client's life. DeYoung acknowledges relational therapy does not make clients invulnerable to pain but gives them the belief they can deal with pain and find support and strength from otherplaces, including within themselves. Therapy is not a magical cure and happiness is not eternal, but the process ofrelational therapy will bring clients to a place of not always expecting the worst or believing that they are the only ones to blame for their unhappiness. Experiencing the feeling of being deeply understood and at the same time understanding others gives clients greater capacity and confidence for dealing with life's struggles. The end of therapy is more than the end of treatment; it is the end of a relationship, which requires space for sadness and recognition of what has been gained. "From the moment ofdiagnosis to the therapist's intention to be-with as fully and as deeply as possible, to the kinds ofgoodness that flow from this connection, relational therapy is always moving away from the fantasy of individual self-sufficiency and towards the realities of human interdependence" (p. 211). A thought-provoking book, DeYoung's style is powerful, illuminating, and incredibly informative as she explores difficult and joyful issues that emerge in any therapeutic relationship. DeYoung succinctly maps out the course ofa therapeutic relationship from beginning to end, addressing difficult questions while emphasizing the self-in-relation to the other and self as an important part of relational therapy. This is a book about beginnings and endings, not only those between client and therapist but also, to some extent, those of the reader.
Hubungan Coping Strategy dengan Adaptational Outcomes pada Ibu Perokok Berat di Kecamatan Bandung Kulon

Abstract. Bandung is one of the cities with a high rate of female smokers. Subdistrict Bandung Kulon has the highest number of women. Smoking behavior was carried out by the mother. Smoking mothers will be more smoke when facing problems such as family problems perceived burdensome in daily life to be a cause of stress. Their reactions vary depending on the cognitive appraisal of smoking mothers. Smoking mothers do attempt to restore to the ideal state when the stress. This concept is called a coping strategy, so that smoking mothers can adjust. Cognitive appraisal and coping impact on the result of adaptation called with adaptational outcomes (Lazarus, 1984). The purpose of this study was to obtain empirical data to determine the extent of the correlation coping strategy with adaptational outcomes in smoking mothers in the sub district of Bandung Kulon. Sampling using purposive sample of heavy smoking mothers in the sub district of Bandung Kulon. Samples were obtained as many as 31 people. Collecting data using measuring devices Ways of Coping from Lazarus & Folkman and Adaptational outcomes measurement tool constructed based on the theory of Lazarus & Folkman , 1984 . Processing data using statistical methods to test contingency coefficient. The result of study is X 2 hit = 5.553 and C = 0.389, that mean is a weak correlation coping strategy with adaptational outcomes in smoking mothers at sub district Bandung Kulon. Abstrak.

Low Calorie Dieting Increases Cortisol

Objective: To test the hypothesis that dieting, or the restriction of caloric intake, is ineffective because it increases chronic psychological stress and cortisol production—two factors that are known to cause weight gain; and to examine the respective roles of the two main behaviors that comprise dieting—monitoring one's caloric intake and restricting one's caloric intake—on psychological and biological stress indicators. Methods: In a 2 (monitoring vs. not) × 2 (restricting vs. not) fully crossed, controlled experiment, 121 female participants were assigned randomly to one of four dietary interventions for 3 weeks. The monitoring + restricting condition tracked their caloric intake and restricted their caloric intake (1200 kcal/day); the monitoring only condition tracked their caloric intake but ate normally; the restricting only condition was provided 1200 kcal/day of food but did not track their calories, and the control group ate normally and did not track their intake. Before and after the interventions, participants completed measures of perceived stress and 2 days of diurnal saliva sampling to test for cortisol. Results: Restricting calories increased the total output of cortisol, and monitoring calories increased perceived stress. Conclusions: Dieting may be deleterious to psychological well-being and biological functioning, and changes in clinical recommendations may be in order. HPA = hypothalamic-pituitary-adrenocortical; PSS = Perceived Stress Scale; CAR = cortisol awakening response.
Analysis of Low Frequency Drain Current Model for Silicon Nanowire Gate-All-Around Field Effect Transistor

This paper is investigated the low frequency noise behavior in subthreshold regime of gate-all-around silicon nanowire field effect transistors. Downscaling of multi gate structure beyond 50 nm gate length describes the quantum confinement related model. A drain current model has been described for output characteristics of silicon nanowire FET that is incorporated with velocity saturation effects and compact modeling of RF noise behavior is analyzed for gate-all-around structure. Noise performance of gate-all-around transistor is investigated at high frequency band for radio frequency RF specified application and consequently low frequency noise behavior can be analyzed using drain current model. This paper shows that noise is decreasing with frequency. Higher subthreshold, lower drain induced barrier lowering DIBL, higher on-off ratio and higher noise figure at lower frequency is achieved by gate all around configuration and comparison has been done with double gate structure.
A Fluid Model for Aggregate TCP Connections

It is well known that the large majority (more than 90%) of IP traffic on the Internet is today carried by TCP connections. Moreover, it is quite realistic to suppose that the largest part of best effort traffic will use TCP also in the future. So, this protocol is and will be a fundamental element for the evaluation and forecast of IP network performance. TCP has been studied for many years, and a lot of models have been proposed for it that can be found in the scientific literature. However, most of them are related to a single connection behavior. In this respect, the aim of this work is to propose a model for aggregate TCP flows that could give a good representation of TCP performance in a network with an acceptable level of precision but also of complexity. Our model can be consider a “fast” simulation model, i.e. it is based on a sort of simulation (event generations and performance measures), which, however, is very fast, because it operates at aggregate level by using a fluid approximation, so that the computational time it requires is comparable to that required by a relative by complex analytical model. The paper reports several tests and comparisons with NS2 simulations, which show the quite good precision of the proposed TCP model. Keywords—TCP connections modeling, Networks modeling, TCP performance evaluation.
Effects of amplitude envelope cues as an aid to enhanced speechreading

This thesis developed methods of presenting two speech envelope cues in the small bandwidth likely to be available to people with severe hearing impairments. Identifying such methods could facilitate face-to-face communication substantially. Seven presentation conditions were evaluated. Two of the conditions, the OneEnvelope Monaural and the Two-Envelope Monaural, were developed by Grant, Braida and Renn (1991), and were used as a basis of comparison to the new conditions developed. The One-Envelope "Rough" Monaural, Two-Envelope "Rough" Monaural, Simple Binaural, Combination Binaural, and Low Binaural are the five presentation conditions developed in this project. Initial tests used normal hearing subjects to evaluate each proposed scheme. This avoided compounding perceptual interference factors with hearing loss. To ensure that these tests were indicative of the full potential of each method, subjects were familiarized with the envelope cues prior to testing. Results of testing suggest that two of the new presentation conditions may prove beneficial to the hearing impaired. Both the Two-Envelope "Rough" Monaural and the Combination Binaural conditions were particularly successful in conveying speech (average scores using Harvard sentences were 74.1% and 72.1%, respectively).

A comparative population genetic study on calanoid freshwater copepods: Investigation of isolation‐by‐distance in two Eudiaptomus species with a different potential for dispersal

We examined patterns of genetic isolation‐by‐distance in two sister species of freshwater copepods, Eudiaptomus graciloides and Eudiaptomus gracilis, using the polymorphism of microsatellite markers. We assumed an enhanced dispersal potential of the species possessing diapausing eggs (E. graciloides) compared with E. gracilis with no diapause. On a longitudinal gradient spanning from northern Germany to Russia, we sampled 17 E. graciloides populations and 16 E. gracilis populations in order to investigate the scale dependence of isolation‐by‐distance from 0.4 to 1,340 km distance. In the 100–1,000 km range, no isolation could be detected in either Eudiaptomus species, suggesting either similar moderate gene flow over large geographic distances or persistence of historic patterns after postglacial recolonization. Our hypothesis was partly supported at the small‐scale level (100 km range) where differences in population structure among species existed. We found isolation‐by‐distance in E. graciloides, the species with resting eggs, whereas E. gracilis exhibited a pattern of persistent founder effects. Further, in E. graciloides we found significant isolation‐by‐distance in the 1,340 km range with significantly reduced gene flow at distances >1,000 km. In E. gracilis, isolation‐by‐distance at distances >1,000 km could not be detected with our data because this species was not found in the Russian lakes. Our results suggest that short‐ and long‐distance dispersal in Eudiaptomus are due to different processes, with diapausing eggs only being advantageous for shortdistance dispersal. We also argue that different spatial scales must be sampled to understand the geographic partitioning of genetic variance at marker loci.
