Hierarchical coding based on adaptive multilevel bit-interleaved channels

Hierarchical coding based on adaptive multilevel bit-interleaved channels is discussed. The proposed code construction has advantages in the simplified design, robustness against channel variations and flexibility in matching itself to the associated source encoder. Multilevel coded modulation with multistage decoding, and bit-interleaved coded modulation are special cases of this general framework.
Online handwritten signature recognition by length normalization using up-sampling and down-sampling

With the rapid advancement of capture devices like tablet or smart phone, there is a huge potential for online signature applications that are expected to occupy a large field of researches in forthcoming years. Online handwritten signature encounters difficulty in the verification process because an individual rarely produce exactly the same signature whenever he signs. This difference in the produced signature is referred to as intra-user variability. Verification difficulty occurs especially in the case where the feature extraction and classification algorithms are designed to classify a stable length vector of input features. In this paper, we introduce an efficient algorithm for online signature length normalization by using Up-Sampling and Down-Sampling techniques. Furthermore, online signature verification system is also proposed by using both Principal Component Analysis (PCA) for feature extraction and Artificial Neural Network (ANN) for classification. The SIGMA database, which has more than 6,000 genuine and 2,000 forged signature samples taken from 200 individuals, is used to evaluate the effectiveness of the proposed technique. Based on the tests performed, the proposed technique managed to achieve False Accept Rate (FAR) of 5.5% and False Reject Rate (FRR) of 8.75%.
Generic functions for on-chip vision

A smart retina is a device which intimately associates an optoelectronic layer with processing facilities. The rapprochement between acquisition and processing is particularly suited for the emergence of novel kinds of interaction, between analog and digital massive computations. Therefore, several attempts of analog, possibly neural, computations linked to the vision process are listed and discussed. But analog is not enough for really smartening retinas. Then, an additional plausible coat of cellular boolean iterative processing in these 'human size' vision machines is described, and commented on through examples. <<ETX>>
Padrões tomográficos das doenças intersticiais pulmonares difusas com correlação clínica e patológica High-resolution computed tomography patterns of diffuse interstitial lung disease with clinical and pathological correlation

High-resolution computed tomography (HRCT) is the radiological imaging technique best suited to revealing changes in lung structure. Various HRCT findings, taken together, can represent typical patterns. These patterns, in conjunction with the anatomical distribution of findings and with clinical data, can narrow the differential diagnosis of diffuse interstitial lung disease and, in many cases, indicate the correct diagnosis with a high degree of accuracy. The most common HRCT patterns seen in cases of diffuse interstitial lung diseases are the nodular pattern, linear/reticular opacities, cystic lesions, ground-glass opacities and consolidations. This article reviews the correlations between HRCT patterns and pathologic findings, summarizing the most common causes, as well as detailing the methods of investigation employed in order to diagnose the most common types of chronic diffuse lung disease.
Multisensor integration in biological systems

The authors discuss the integration of sensory information in biological systems. In particular, they consider the structure in vertebrate animals that utilizes multiple sensory inputs to orient the sensor platform, i.e. the body or the head, toward objects of interest. This structure is known as the optic tectum in lower vertebrates and the superior colliculus in mammals. The representation of the various sensory modalities on the tectum follows the maplike image format of the retina. This requires in some cases a considerable transformation from the original representation of the sensory input available from the other sensors. As an example, the authors present a detailed discussion of the visual/acoustic object localization system of the barn owl along with a model for the adaptive coregistration of the coordinate systems of the visual and acoustic maps on the tectum. <<ETX>>
NUTRACÉUTICOS: USO DE HARINA DE CUCARACHA DE MADAGASCAR (Gromphadorhina portentosa) EN LA ALIMENTACIÓN DE POLLOS EN ETAPA DE DESARROLLO

El objetivo del presente estudio fue analizar la ganancia diaria de peso (GDP) y consumo diario de alimento en etapa de desarrollo usando harina de cucaracha de Madagascar (Gromphadorhina portentosa) como fuente de proteina. Se utilizo una muestra de Gromphadorhina portentosa en fase adulta, la cual fue secada al horno y procesada mediante molienda. Se hicieron uso de 2 tratamientos integrados por 3 pollos tomados totalmente al azar, donde el T1 como testigo y el T2 el tratamiento con una concentracion de harina de cucaracha de Madagascar obteniendo del 20% de proteina total en la dieta. Los pollos fueron pesados al inicio y cada tres dias, a partir del dia 10 de vida hasta el dia 23. Se utilizo un diseno experimental completamente al azar, se realizo un analisis de varianza y una comparacion de medias por Tukey (α=0.05). Los resultados obtenidos fueron un menor consumo de alimento al utilizar la harina de cucaracha de Madagascar, y una mayor GDP, por lo que se recomienda incluirla en la dieta en etapa de desarrollo.
Características da morte súbita tida como não esperada na doença de Chagas

Thirty five individuals who died suddenly and unexpectedly were autopsied at Medico-Legal Services in Uberaba and Uberlandia (State of Minas Gerais-Brazil). Serology of the pericardial fluid and histopathological findings established a diagnosis of Chagas' disease. All, with two exceptions were males and their mean age was 38 years. We decided to conduct a retrospective investigation regarding the manner of death of chagasic patients who died suddenly from information obtained from family members and friends. The questionaire explored possible cardiac and systemic factors related to the risk of such an event. In 31.2% there were no symptoms norsuspicion of cardiopathy. However, in 57,1% it was possible to detect a history of dizziness (42,8%), dyspnoea on exertion(48%), loss of conciousness (34,2%) andpalpitations (31,4%). Dysphagia and or constipation was present in 38%. There was no correlation between symptomatology and the intensity of myocarditis on histopathological examination. In 56% the death occurred during physical exercise oran emotionalepisode. From the mannerof death we can conclude that there was no indication that such an event would occur in 43.8% of patients. In the rest the death waspreceeded by signs on thepart of the patient that he was in difficulty. Electrocardiograms were available from only fivepatients: all were abnormal.
Review Article: Is sitting-while-at-work associated with low back pain? A systematic, critical literature review

Objectives: To present a critical review and evaluate recent reports investigating sitting-while-at-work as a risk factor for low back pain (LBP). Methods: The Medline, Embase and OSH-ROM databases were searched for articles dealing with sitting at work in relation to low back pain for the years 1985-97. The studies were divided into those dealing with sitting-while-working and those dealing with sedentary occupations. Each article was systematically abstracted for core items. The quality of each article was determined based on the representativeness of the study sample, the definition of LBP, and the statistical analysis. Results: Thirty-five reports were identified, 14 dealing with sitting-while-working and 21 with sedentary occupations. Eight studies were found to have a representative sample, a clear definition of LBP and a clear statistical analysis. Regardless of quality, all but one of the studies failed to find a positive association between sitting-while-working and LBP. High quality studies found a marginally negative association for sitting compared to diverse workplace exposures, e.g. standing, driving, lifting bending, and compared to diverse occupations. One low quality study associated sitting in a poor posture with LBP. Conclusions: The extensive recent epidemiological literature does not support the popular opinion that sitting-while-at-work is associated with LBP.
Tratamiento biológico–ultrasónico nueva alternativa en la degradación de polipropileno

espanolEl polipropileno es un material ampliamente utilizado por su gran variedad de aplicaciones y facilidad de manejo, su uso indiscriminado ha generado un grave problema ambiental, debido a su acumulacion y largos periodos de degradacion, aproximadamente 100 anos. Este problema nos ha llevado a interesarnos en investigar nuevas alternativas de degradacion. En el presente trabajo de investigacion se combinaron dos metodos de degradacion, uno biologico (Phanerochaete chrysosporium) y otro fisico (ultrasonico) con el fin de abatir el tiempo de degradacion. El polipropileno se inoculo con Phanerochaete chrysosporium y se sonico en bano ultrasonico a 43 kHz, variando el tiempo de degradacion. El polipropileno se caracterizo despues del tratamiento por FTIR–ATR, observando la presencia de grupos carbonilo y vinilo, promovidos por la escision–β de la cadena principal de polipropileno. La MEB mostro la morfologia antes y despues del proceso de degradacion, observandose la formacion de una biocapa en la superficie de la membrana y rompimiento de fibras posterior a las 100 horas de reaccion. El angulo de contacto y pruebas mecanicas corroboran la presencia de los grupos polares en la superficie del polipropileno, observando disminucion de la hidrofobia, y de la resistencia a la traccion favoreciendo su degradacion. EnglishPolypropylene is a material widely used for its large variety of applications and easy to use, their indiscriminate use has generated a serious environmental problem, due to their accumulation and the long periods, approximately 100 years. We are interested to investigate a new alternative of degradation. This research involves two methods of degradation, one of them is biological (Phanerochaete chrysosporium) and the other is physical (ultrasound) in order to reduce the degradation time. The Polypropylene was inoculate with Phanerochaete chrysosporium, and sonicated using an ultrasonic bath to 43 kHz by several degradation time. The polypropylene was characterize by FTIR–ATR, observing the presence of carbonyl and vinyl groups, promoted by β–cleavage of the backbone of polypropylene. SEM showed the morphology before and after degradation process, the formation of biofilm on the membrane surface and subsequent breaking of fibers at 100 hours reaction was observe. The contact angle and mechanical tests confirm the presence of polar groups on the polypropylene surface, the hydrophobicity and the tensile strength decreased favoring its degradation.

Epidemiología de las enfermedades cerebrovasculares de origen extracraneal

Introduction: the cerebrovascular illnesses are a world health problem; they hold the third place among the diseases in Cuba, but the particular place of the carotid artery diseases is still unknown. Objectives: to update the epidemiologic information on the cerebrovascular diseases, particularly those of extracranial origin. Methods: the information was collected from the following databases: register of trials of the Cochrane Peripheral Vascular Diseases Group, the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Library, MEDLINE, PubMed, leading journals with cerebrovascular disease studies, and articles in different web pages published in the last five years. The subject headings were epidemiology, cerebrovascular illness, carotid disease. Information synthesis: in the western countries, the cerebrovascular diseases are the third cause of mortality after the cardiovascular diseases and neoplasias, accounting for 10% of deaths. They are the first cause of disability in the adult and the second cause of dementia. According to the World Health Organization, 15 million persons suffer ictus every year; 5.5 millions die (10 % of all deaths) and 5 millions show some permanent disability. Although the incidence rate is higher in the elderly, a shift to youngest ages has been observed. Conclusions: the cerebrovascular disease is a prevailing illness with high morbidity and mortality rates, which demands a lot of care and hospitalization with considerable health and social costs.

Research Article Otological and audiological manifestations in cleft lip and cleft palate children: a clinical study

Background: Cleft lip and cleft palate are the commonest congenital anomalies of the orofacial region. The incidence of middle ear problems and hearing loss is reported to be higher in children with cleft palate &/or cleft lip. Methods: A prospective, observational case-control study comprising 80 subjects (40 cases and 40 controls) was undertaken at Yenepoya Medical College Hospital, Mangalore, Karnataka, India. All subjects enrolled were subjected to detailed ENT examination including otoscopy, pure tone audiometry and impedance audiometry. Results: Retracted tympanic membrane suggestive of Otitis Media with Effusion (OME) and conductive hearing loss was observed in more than 50% of patients with cleft palate &/or cleft lip. Tympanogram of B type suggesting OME was observed in 27% of cases. Chronic otitis media was observed in 32.5% of cases. Conclusions: The prevalence of OME, Chronic otitis media and hearing loss was observed to be higher among children with cleft palate &/or cleft lip. Otological and audiometric assessment should be performed for all patients having cleft palate &/or cleft lip atleast before surgery in order to facilitate early identification and intervention for middle ear problems particularly middle ear effusion.
Hospital anxiety and depression in myocardial infarction patients

The National Service Framework for Coronary Heart Disease recommends that psychological support should be offered to those patients who require it. 1 A six-month study carried out at Darlington Memorial Hospital looked at psychological support needed by patients following myocardial infarction (Ml). The psychological status of Ml patients was formally assessed using the Hospital Anxiety and Depression (HAD) scale 2,3 and appropriate referrals were made to psychological support services to improve patient management. The study also measured the impact that formal assessment of the psychological status of Ml patients would have on service providers. Some 80 Ml patients from the Darlington primary care trust (PCT) were eligible for inclusion in the study. Psychological assessment was undertaken at four stages during cardiac rehabilitation and 25 patients were eligible for referral for psychological support as a result of high HAD scores measured during the study period. Ten patients accepted referral, a higher number than during the previous six-month period when HAD scales had not been used. Eight patients were referred to occupational therapy services for help with anxiety issues, one patient was referred to the psychology service and one to liaison psychiatry. Both of these patients required help with depression. The study also found a high degree of patient satisfaction. The support received may also be required by many other groups of patients.
Design and microcontroller‐based hardware performance analysis of a security‐enhanced lightweight communication scheme for smart grid

In smart grid, usage reports of consumers are collected via the smart meters (SMs) and sent to the power management and control center. In addition, some instructions are sent from the control center to the SMs. These two‐way communications between customers and energy suppliers are subject to numerous security threats. Due to the limited processing capability and storage space of the SMs, it is required to employ lightweight communication schemes. To do so, quite recently, Liu et al have proposed an interesting lightweight authenticated communication scheme for the secure bidirectional communications of SMs and neighborhood gateways in smart grid. In this paper, we first demonstrate that their scheme suffers from the SM's memory modification attack and pollution attack, then, we propose an enhanced lightweight communication scheme that is secure against the mentioned attacks. The comparative performance analysis with recent works in this field shows that our scheme not only is more efficient in terms of computational complexity and communication cost, but also benefits from substantial reduction in the required storage space. Our realistic hardware implementation on two popular microcontrollers confirms this claim.
Real-Time Constrained Trajectory Planning and Vehicle Control for Proactive Autonomous Driving With Road Users

For motion planning and control of autonomous vehicles to be proactive and safe, pedestrians' and other road users' motions must be considered. In this paper, we present a vehicle motion planning and control framework, based on Model Predictive Control, accounting for moving obstacles. Measured pedestrian states are fed into a prediction layer which translates each pedestrians' predicted motion into constraints for the MPC problem. Simulations and experimental validation were performed with simulated crossing pedestrians to show the performance of the framework. Experimental results show that the controller is stable even under significant input delays, while still maintaining very low computational times. In addition, real pedestrian data was used to further validate the developed framework in simulations.
