The goal of any Model Order Reduction (MOR) technique is to build a model of order lower than the one of the real model, so that the computational effort is reduced, and the ability to estimate the input-output mapping of the original system is preserved in an important region of the input space. Actually, since only a subset of the input space is of interest, the matching is required only in this subset of the input space. In this contribution, the consequences on the achieved accuracy of adopting different reduction technique patterns is discussed mainly with reference to a linear case study.
This paper investigates the possibility of a strategy for an automatic full recover of a structural component undergoing loading-unloading (fatigue) cycles: full recover means here that no replacement is required at the end of the mission. The goal is to obtain a material capable of self healing earlier before the damage becomes irreversible. Attention is focused on metallic materials, and in particular on shape memory alloys, for which the recovering policy just relies on thermal treatments. The results of several fatigue tests are first reported to acquire a deep understanding of the physical process. Then, for cycles of constant amplitude, the self-healing objective is achieved by mounting, on the structural component of interest, a suitable microcontroller. Its input, from suitable sensors, covers the current stress and strain in the alloy. The microcontroller elaborates from the input the value of a decisional parameter and activates the thermal process when a threshold is overcome.

Within a noted literature regarding Holism, Secretan (2006) mentioned that any single part of a whole cannot exist by itself independently. If you do not understand the whole, you cannot also realize the individual separately. In fact, the whole is more important than the summation of each of the separate part. This notion accurately describes what human beings truly need within the current 21 st century. Our century is an ever changing era, more important, we live in a time of great fear and stress. To better understand and cope with this situation, the current presentation shall introduce more on the manmade emergencies and crisis instead of natural disaster since there are a lot of information on the natural disasters publicized by the government. This presentation will cover four main points, including 1) we are living in a complex, diverse, and dramatic changing world, 2) the system of preventing and managing crises and emergency in Taiwan education, 3) noted examples on how crises were dealt with during unexpected fire at Formosa Fun Coast Water park; wherein many young friends suffered not only from skin burns but also loss of skin, and 2014 Taipei Metro attack will be addressed. Finally, recommendations shall be made in initialing programs such as life education, servant leadership, and Peace Study. In effect, educating more happy Servant-Leaders for the next generation becomes a reality.

Objective Despite several studies that have highlighted the harmful effects of alcohol consumption on cognitive functions it remains unclear whether certain brain areas are more sensitive than others are or whether alcohol causes widespread cognitive deficit. Moreover, the role of continued abstinence has yet to be clarified regarding the quality of recovery on the different cognitive domains. The aim of this 1-year longitudinal study was to evaluate the recovery of cognitive deficits in the medium (6 months) and long term (12 months) after the interruption of drinking. Methods Forty-one alcohol-dependent patients were recruited from two outpatient treatment facilities and cognitive functions were compared on a control group of forty healthy controls. The patients were then re-assessed at 6 and 12 months. Changes in neuropsychological measures were evaluated with repeated measures analysis of variance (ANOVA). We also compared 1-year follow-up scores with control data (unpaired t tests) to identify tests on which significant differences persisted. Results Patients performed significantly worse than controls in all cognitive domains investigated and this cognitive impairment was evident in recently abstinent patients. A year of abstinence resulted in a significant improvement in all cognitive domains assessed after detoxification from alcohol. After year 1, alcoholic subjects had returned to normal levels compared to healthy controls on all domains except for general non-verbal intelligence, verbal memory and some visuospatial skills. Conclusion Our results support the hypothesis of widespread impairment resulting from alcohol consumption. The recovery of cognitive functions is not homogeneous during prolonged abstinence.
For the purpose of determining the pathogenic role of transforming growth factor- 1 (TGF- 1) in the mechanism of chronic rheumatic heart disease, we evaluated the expression of TGF- 1, proliferation of myofibroblasts, and changes in extracellular matrix components including collagen and proteoglycan in 30 rheumatic mitral valves and in 15 control valves. High TGF- 1 expression was identified in 21 cases (70%) of rheumatic mitral valves, whereas only 3 cases (20%) of the control group showed high TGF- 1 expression (p<0.001). Additionally, increased proliferation of myofibroblasts was observed in the rheumatic valves. High TGF- 1 expression positively correlated with the proliferation of myofibroblasts (p=0.004), valvular fibrosis (p< 0.001), inflammatory cell infiltration (p=0.004), neovascularization (p=0.007), and calcification (p<0.001) in the valvular leaflets. The ratio of proteoglycan to collagen deposition inversely correlated with TGF- 1 expression in mitral valves (p=0.040). In conclusion, an ongoing inflammatory process, the expression of TGF- 1, and proliferation of myofibroblasts within the valves have a potential role in the valvular fibrosis, calcification, and changes in the extracellular matrix that lead to the scarring sequelae of rheumatic heart disease.
In this work, pollen mother cells (PMCs) isolated in Arabidopsis thaliana by laser-capture microdissection (LCM) were subjected to transcription profiling by microarray (LMM). PMCs covering all meiotic stages, from leptotene to tetrad, were collected in an Atmcc1 characterized by overexpression of a GCN5-like histone acetylase (AtMCC1). A total of 150 genes showed differential expression in Atmcc1PMCs as compared to the wild type. Histone hyperacetylation affected the transcription of genes belonging to categories such as the meiotic and mitotic cycle, the ubiquitinproteasome-system, and the chromatin structure. We also discuss the putative role of ASK1 and RAD51C upregulation in the meiotic defects observed in Atmcc1. PMCLMM experiments allowed identification of candidate AtMCC1 targets with known and potential function in meiosis, providing data for further investigation on plant meiosis.
