A biologically inspired model for pattern recognition

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2010年第2期11卷 115-126页

作者： eduardo GONZALEZ Hans LILJENSTROM Yusely RUIZ Guang LI Department of Biomedical Engineering Zhejiang University Hangzhou 310027 China Department of Energy and Technology Swedish University of Agricultural Sciences Box 7013 SE-750 Sweden National Laboratory of industrial Control Technology Institute of Cyber-Systems and Control Zhejiang University Hangzhou 310027 China

In this paper, a novel bionic model and its performance in pattern recognition are presented and discussed. The model is constructed from a bulb model and a three-layered cortical model, mimicking the main features of the olfactory system. The olfactory bulb and cortex models are connected by feedforward and feedback fibers with distributed delays. The Breast Cancer Wisconsin dataset consisting of data from 683 patients divided into benign and malignant classes is used to demonstrate the capacity of the model to learn and recognize patterns, even when these are deformed versions of the originally learned patterns. The performance of the novel model was compared with three artificial neural networks (ANNs), a back-propagation network, a support vector machine classifier, and a radial basis function classifier. All the ANNs and the olfactory bionic model were tested in a benchmark study of a standard dataset. Experimental results show that the bionic olfactory system model can learn and classify patterns based on a small training set and a few learning trials to reflect biological intelligence to some extent.

To achieve this purpose, both grass species were grown for up to 480 hr in a nutrient solution containing 0.019 or 7 mmol/L Fe-EDTA after the root apices had been removed or maintained. Cultivation in the presence of excess iron-induced leaf bronzing and the formation of iron plaque on the root surfaces of both grass species, but was more significant on those plants whose root apex had been removed. Iron accumulation was higher in the roots, but reached phytotoxic levels in the aerial parts as well. It did not hinder the biosynthesis of chloroplastidic pigments. No significant changes in gas exchange and chlorophyll a fluorescence occurred in either grass when their roots were kept intact; the contrary was true for plants with excised root apices. In both studied grasses, the root apoplastic barriers had an important function in the restriction of iron translocation from the root to the aerial plant parts, especially in E. crus-galli. Root apex removal negatively influenced the iron toxicity resistance mechanisms(tolerance in P. densum and avoidance in E. crus-galli).

Uncontrolled hypertension in older patients： markers and associated factors to masked and white-coat effect

Journal of Geriatric Cardiology 2016年第8期13卷 672-678页

作者： Nereida KC Lima Julio C Moriguti eduardo Feniolli Division of General lnternal Medicine & Geriatrics Internal Medicine Department Ribeirao Preto Medical School Sao Paulo University Sao Paulo Brazil

Background Hypertension is the main risk factor for cardiovascular diseases, affecting more than half the elderly population. It is essential to know if they have proper control of hypertension. The aim of this study was to identify the associated factors to masked uncon- trolled hypertension and false uncontrolled hypertension in older patients. Methods Two-hundred seventy-three individuals （70.1±6.7 years-old） had blood pressure （BP） measured at the office and by ambulatory BP monitoring （ABPM）, with the definition of controlled group （C）, individuals with high office BP and adequate ABPM, called white-coat effect group （WCE）, uncontrolled （UC）, and subjects with ap- propriate office BP and elevated ABPM denominated masked effect group （ME）. Age, body mass index, diabetes, pulse pressure （PP） and BP dipping during sleep were evaluated （Kruskal-Wallis test and logistic regression models）. Results Age was higher in UC than in C and ME （P 〈 0.01）, and 24-h ABPM PP was lower in C （48± 7 mmHg） and WCE （51±6 mmHg） than in UC （67±12 mmHg） and ME （59±8 mmHg）（P 〈 0.01）. Sleep systolic BP dipping was lower in ME than in C （P = 0.03）. Female gender was associated with a greater chance of being of ME group, which showed a higher PP and lower BP dipping during sleep. Conclusions In older individuals, office BP measure- ments did not allow the detection of associated factors that would permit to differentiate WCE from UC group and C from ME group. ABPM favored the identification of a higher PP and a lower BP dipping during sleep in the masked effect and uncontrolled groups.

Numerical analysis of rapid drawdown: Applications in real cases

Water Science and Engineering 2016年第3期9卷 175-182页

作者： eduardo E. Alonso Nuria M. Pinyol Department of Civil and Environmental Engineering Universitat Politecnica de Catalunya (UPC) Barcelona 08034 Spain Centre Internacional de Metodes Numerics en Enginyeria (CIMNE) Barcelona 08034 Spain

In this study, rapid drawdown scenarios were analyzed by means of numerical examples as well as modeling of real cases with in situ measurements. The aim of the study was to evaluate different approaches available for calculating pore water pressure distributions during and after a drawdown. To do that, a single slope subjected to a drawdown was first analyzed under different calculation alternatives, and numerical results were discussed. Simple methods, such as undrained analysis and pure flow analysis, implicitly assuming a rigid soil skeleton, lead to significant errors in pore water pressure distributions when compared with coupled flow-deformation analysis. A similar analysis was performed for the upstream slope of the Glen Shira Dam, Scotland, and numerical results were compared with field measurements during a controlled drawdown. Field records indicate that classical undrained calculations are conservative but unrealistic. Then, a recent case of a major landslide triggered by a rapid drawdown in a reservoir was interpreted. A key aspect of the case was the correct characterization of permeability of a representative soil profile. This was achieved by combining laboratory test results and a back analysis of pore water pressure time records during a period of reservoir water level fluctuations. The results highlight the difficulty of predicting whether the pore water pressure is overestimated or underestimated when using simplified approaches, and it is concluded that predicting the pore water pressure distribution in a slope after a rapid drawdown requires a coupled flow-deformation analysis in saturated and unsaturated porous media.

Background: The activities carried out by soldiers in the army involve great physical demands and require intense trainings to perform combat-specific tasks. Musculoskeletal injury is a potential threat to the health and physical integrity of the soldier. This study aimed to evaluate the prevalence of lower limb musculoskeletal injuries among soldiers and to propose a training protocol to prevent the most frequent ***: This observational(cross-sectional) study recruited a sample of 103 soldiers who required medical attention,from a total 202 new battalion soldiers. The medical records(paper and online) had a form of running text. All data collected were recorded by the registered physicians of the battalion medical post. The records were analyzed by the following variables: medical diagnosis, injury site, mechanism, type of treatment, time loss, existence of previous injury,and recurring ***: A total of 112 musculoskeletal injuries were diagnosed in 71 soldiers, and other types of diseases/injuries were diagnosed in the other soldiers. Joint pain accounted for 55.4% of the diagnoses. The knee was the most affected site, while trauma and overload were the most common mechanisms of injury. Drug treatment was used most frequently, accounting for 58% of the cases. The majority of the sample obtained a temporary leave of absence for1 to 6 days or not at all. Previous injuries and recurrence were not presented as risk factors for injury. With the data received, a protocol for the prevention of injuries to the lower limbs was ***: This study indicated that the most frequent site of injury is the knee, and joint pain is the most common diagnosis. These results may support the necessity to develop a neuromuscular training protocol to prevent lower limb injuries, which we suggest to be applied in future studies.
