[Short-term impact of an ambulatory cardiac rehabilitation program on arterial rigidity].

BACKGROUND
If the positive impact of cardiac rehabilitation on metabolic profile and exercise tolerance is well documented in the literature, very few studies evaluated the impact of these rehabilitation programs on arterial rigidity.


PURPOSE
The main objective of this study was to determine if a short and intense 4-week cardiac rehabilitation program could yield a positive impact on arterial rigidity.


METHOD
A cohort study was performed on Leopold Bellan Foundation. All patients referred for cardiac rehabilitation program after an acute event (surgery, technical gesture or acute decompensate heart failure) were included in this study. Our CR program consists of four sessions per week for five weeks (total of 20 sessions) and includes both exercise and health and nutrition education sessions. In addition to clinical and therapeutic data collection, biochemical analysis for carbohydrate and lipid metabolism and exercise capacity measurements, carotid femoral pulse wave velocity (PWV) were measured in a quiet room in the morning of their first and last day prior to any exercise.


RESULTS
One hundred and ninety-eight cardiac patients have participated in this study, of which 79% were male, mean age 60 ± 10, 50 (25%) were diabetic, 103 (52%) were hypertensive, 60 (30%) were current smokers, 98 (50%) had dyslipidemia, and 140 (71%) were referred for cardiac rehabilitation after acute coronary syndrome. Arterial stiffness is defined by a VPWV value greater or equal to 10. At the beginning, 59% of our patients have rigid arteries. After 20 sessions of cardiac rehabilitation, this number is significantly reduced to 51% (P=0.12). Patients with arterial stiffness have accumulated more major cardiovascular risk factors, and have had less exercise capacity than others. However they benefit similarly from the cardiovascular rehabilitation program.


CONCLUSION
In the present study, we observed that arterial stiffness, as reflected by the PWV, tends to decrease after short-term ambulatory cardiac rehabilitation program.
Board level solder joint reliability analysis of a fine pitch Cu post type wafer level package (WLP)

Wafer level packaging (WLP) has many advantages, such as ease of fabrication and reduced fabrication cost. However, solder joint reliability of traditional WLPs is the weakest point of the technology. In this paper, a 0.4 mm pitch Cu post type WLP has been developed for mobile computing application. The Cu post type WLP has 440 I/Os and 12 · 12 mm die size. The initial design WLP has been fabricated and subjected to a thermal cycling (TC) testing. The failure life of the original WLP under TC was 296 cycles. This paper also presents a nonlinear finite element analysis of the board level solder joint reliability and methods for enhancement of the WLP. A viscoplastic constitutive relation is adopted for the solder joints to account for its time and temperature dependence in TC. The fatigue life of the solder joint is estimated by the modified Coffin–Manson equation. The two coefficients in the modified Coffin–Manson equation are also determined. A series of parametric studies are performed by changing the passivation (PI) thickness, redistribution layer (RDL) thickness, polymer height (Cu post height accordingly varies), die thickness, PCB thickness, and PCB CTE. The results obtained from the modeling are useful to formulate design guidelines for board level reliability enhancement of the WLP. 2007 Elsevier Ltd. All rights reserved.
Role of health hazardous ethephone in nutritive values of selected pineapple, banana and tomato

An experimental study of selected pineapple (Ananas sativus), banana (Musa acuminata) and tomato (Lycopersicon esculentum) was investigated on the basis of their biochemical and nutritional properties by the treatment of some doses of ethephone. It was found that the chemically treated samples ripened rapidly than untreated ones. The nutritional properties of chemically ripened fruits as well as market samples (ripe) were shown different from untreated. The chemically ripened samples showed shorter shelf life than non-treated samples. The highest vitamin C content of the selected non-treated fruits (17.5 mg/100 g in pineapple, 13 mg/100 g in banana and 20.2 mg/100 g tomato) and the lowest contentwas found in the market samples (10 mg/100 g in pineapple, 7 mg/100 g in banana and 12.3 mg/100 g tomato), whereas ethephone-treated groups contained the ascorbic acid 14.5 mg/100 g in pineapple, 9 mg/100 g in banana and 19.4 mg/100 g in tomato). Similarly the β-carotene content of ethephone-treated samples (63 μg/100 g in pineapple, 47 μg/100 g in banana and 757 μg/100 g in tomato) and market samples (31 μg/100 g in pineapple, 38 μg/100 g in banana and 512 μg/100 g in tomato) were less than that of control groups (78 μg/100 g in pineapple, 54 μg/100 g in banana and 807 μg/100 g in tomato). The mineral contents of samples in three groups showed ethephone-treated samples indicated less nutritional quality than untreated samples. Higher amount of lead and arsenic were found in all fruits and vegetables in both ethephone-treated and market samples but the concentrations were within acceptable limits.
Wide-band microwave propagation parameters using circular and linear polarized antennas for indoor wireless channels

This paper presents results of experiments using a variety of antennas inside several buildings. Path loss models are presented for the 1.3 GHz and 4.0 GHz bands, and indicate little difference in indoor path loss throughout the low-microwave region. Results show that line-of-sight (LOS) channels offer significantly more cross-polarization discrimination than obstructed (OBS) channels. A profound result is that directional circularly polarized (CP) antennas always reduce rms delay spread when compared to omnidirectional and directional linearly polarized (LP) antennas in LOS. The variation of rms delay spread as a mobile moves over several wavelengths is also greatly reduced when CP antennas are used.
Power electronics' circuit topology - the basic switching cells

Abstract—In this paper, two basic switching cells, P-cell and Ncell, are presented to investigate the topological nature of power electronics circuits. Both cells consist of a switching device and a diode and are the basic building blocks for almost all power electronics circuits. The mirror relationship of the P-cell and Ncell will be revealed. This paper describes the two basic switching cells and shows how all dc-dc converters, voltage source inverters, current source inverters, and multilevel converters are constituted from the two basic cells. Through these two basic cells, great insights about the topology of all power electronics circuits can be obtained for the construction and decomposition of existing power electronic circuits. New power conversion circuits can now be easily derived and invented.
Effects of a 10-week toe-out gait modification intervention in people with medial knee osteoarthritis: a pilot, feasibility study.

OBJECTIVE
To examine the feasibility of a 10-week gait modification program in people with medial tibiofemoral knee osteoarthritis (OA), and to assess changes in clinical and biomechanical outcomes.


DESIGN
Fifteen people with medial knee OA completed 10 weeks of gait modification focusing on increasing toe-out angle during stance 10° compared to their self-selected angle measured at baseline. In addition to adherence and performance difficulty outcomes, knee joint symptoms (Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale and total score, numerical rating scale (NRS) of pain), and knee joint loading during gait (late stance peak knee adduction moment (KAM)) were assessed.


RESULTS
Participants were able to perform the toe-out gait modification program with minimal to moderate difficulty, and exhibited significant increases in self-selected toe-out angle during walking (P < 0.001). Joint discomfort was reported by five participants (33%) in the hip or knee joints, though none lasted longer than 2 weeks. Participants reported statistically significant reductions in WOMAC pain (P = 0.02), NRS pain (P < 0.001), WOMAC total score (P = 0.02), and late stance KAM (P = 0.04).


CONCLUSIONS
These preliminary findings suggest that toe-out gait modification is feasible in people with medial compartment knee OA. Preliminary changes in clinical and biomechanical outcomes provide the impetus for conducting larger scale studies of gait modification in people with knee OA to confirm these findings.
Automatic classification of movie trailers using data mining techniques: A review

Nowadays huge amount of data is generated through various activities. To manage the data in proper format and the way it is to be maintained. There are so many ways to maintain the data. Classification of data is done so as to identify and put that data in different classes. It is nothing but to group that data in different classes and retrieve as and when it is required with ease. The classification of data is to make the user aware the class of that data on the basis of certain attributes. In this paper we basically focus on the movie trailers using different data mining approaches to classify the videos. The amount of video that a viewer has to choose from is now so large that it is infeasible for a human to go through it all to find movie of interest. Here various methods and techniques are discussed for classification of video and movie trailers.
Copy number variation and autism: new insights and clinical implications.

Genomic research can lead to discoveries of copy number variations (CNVs) which can be a susceptibility factor for autism spectrum disorder (ASD). The clinical translation is that this can improve the care of children with ASD. Chromosome microarray is now the first-tiered genetic investigation for ASD, with a detection rate exceeding conventional cytogenetics and any single gene testing. However, interpretation of the results is challenging and there is no consensus on "what" and "how much" to disclose. In this article, we will review how CNV studies have improved our understanding of ASD, the clinical applications, and related counseling issues. Future direction of autism genetic research is also discussed.

This paper reviews the role of multimedia vocabulary annotation (MVA) in facilitating second language (L2) reading and listening activities. It examines the multimedia learning and multimedia language learning theories that underlie the MVA research, synthesizes the findings on MVA in the last decade, and identifies three underresearched areas on the subject.
Diffusion alterations in corpus callosum of patients with HIV.

BACKGROUND AND PURPOSE
Diffusion alterations have been identified in the corpus callosum and frontal white matter of patients infected with human immunodeficiency virus (HIV), though the relevance of these findings to cognitive deterioration has not yet been determined. This study tested the hypothesis that diffusion tensor imaging can detect tissue status alterations in these regions in cognitively impaired patients infected with HIV and the acquired measurements correlate with the severity of cognitive impairment.


METHODS
Fractional anisotropy (FA) and mean diffusivity (MD) were determined for corpus callosum (genu and splenium) and frontal white matter (FWM). The DTI measurements were compared in 11 HIV and 11 control participants. Patterns of relationship were examined with cognitive status measures from concurrent neurologic and neuropsychologic evaluations.


RESULTS
FA values for the splenium were significantly reduced in the patients infected with HIV and correlated with dementia severity and deficits in motor speed. MD values for the splenium were significantly increased in the patients infected with HIV and correlated with deficits in motor speed. FA measurements were also significantly correlated with performance on visual memory (genu), visuoconstruction (FWM), and verbal memory (FWM) tasks.


CONCLUSION
Diffusion abnormalities were identified in the splenium of the corpus callosum in patients infected with HIV, and these alterations were associated with dementia severity and motor speed losses. In vivo assessment of callosal integrity by using quantitative neuroimaging may have potential utility as a marker of brain injury in patients infected with HIV.

Time/duration effectiveness of sildenafil versus tadalafil in the treatment of erectile dysfunction in male spinal cord-injured patients

Study design: A randomized, blinded, crossover clinical trial comparing sildenafil versus tadalafil for erectile dysfunction (ED) in male spinal cord-injured (SCI) patients.Objectives: To compare the safety, time/duration effectiveness, and the impact on the quality of life (QoL) of tadalafil 10 mg versus sildenafil 50 mg.Setting: Neurourology Section, Careggi Hospital, Florence, Italy.Methods: During a screening (visit 1), a diary card was distributed, in which the subjects assessed, after each attempt at intercourse the quality of their erection, responding (Yes/No) to both Sexual Encounter Profile Questions 2 (SEP2) and 3 (SEP3). The subjects made at least four attempts at intercourse. At visit 2, 15 patients (group 1) were assigned sildenafil and 15 (group 2) started with tadalafil. Responses to baseline International Index of Erectile Function 5 items (IIEF-5), Questions 13–14 (IIEF 15 items) and SEP diary were recorded. Patients attempted intercourse on four separate occasions: within 4 h of taking the first tablet, within 12 h for the second tablet, 24 h for the third, and the fourth from 24 to 36 h. At visit 3, the investigators evaluated the effectiveness with the same measures used at baseline. After a wash-out period, at visit 4, Group 1 was given tadalafil, and Group 2 was given sildenafil. Patients were required to observe the same criteria in taking the four tablets as in visit 2. After 4 weeks (visit 5), we evaluated the patients as we did in visit 3.Results: Overall, 28 patients completed the study. No subjects discontinued the drugs due to drawbacks.Tadalafil allowed a majority of men in this trial to achieve both normal sexual functioning up to 24 h postdosing compared to sildenafil (P<0.01) and improved overall sex life satisfaction as well as sexual relations with partner.Conclusion: Based on these data, tadalafil may have the potential to become an important treatment option for ED in SCI patients.Sponsorship: This study was not sponsored.
Impact assessments and policy responses to sea-level rise in three US states: An exploration of human-dimension uncertainties

Uncertainties in the human dimensions of global change deeply affect the assessment and responses to climate change impacts such as sea-level rise (SLR). This paper explores the uncertainties in the assessment process and in state-level policy and management responses of three US states to SLR. The findings reveal important political, economic, managerial, and social factors that enable or constrain SLR responses; question disasters as policy windows; and uncover new policy opportunities in the history of state coastal policies. Results suggest that a more realistic, and maybe more useful picture of climate change impacts will emerge if assessments take more seriously the locally embedded realities and constraints that affect individual decision-makers’ and communal responses to climate change. r 2005 Elsevier Ltd.

Chatbot Enhanced Algorithms: A Case Study on Implementation in Bahasa Malaysia Human Language

Chatbot is one of a technology that tried to encounter the question that popped into computer science field in 1950 which is ”Can machines think?” [6]. Proposed by mathematician Alan Turing, the question later becomes the pinnacle reference for researchers in artificial intelligence discipline. Turing later also introduces ”The Imitation Game” that now known as ”Turing Test” where the idea of the test is to examine whether machine can fool a judge into thinking that they are having a conversation with an actual human. The technology back then was great but in rapid evolution of computer science, it can become even better. Evolution is computer scripting language, application design model, and so on, clearly have its advantage towards enabling more complex features in developing a computer program. In this paper, we propose an enhanced algorithm of a chatbot by taking advantages of relational database model to design the whole chatbot architecture that enable several features that cannot or difficult to be done in previous state of computer science programming technique. Started with some literature of a previous developed chatbot, then a detailed description of each new enhanced algorithm together with testing and results from the implementation of these new algorithms that can be used in development of a modern chatbot. These several new algorithms will enable features that will extend chatbot capabilities in responding to the conversation. These algorithm is actually implemented in design and development of chatbot that specifically deal with Bahasa Malaysia language, but taking to account that language in chatbot is really about the data in chatbot knowledge-based, the algorithm is seems transferable wherever it fits into another human language.
Modeling Liquid−Liquid Equilibrium of Ionic Liquid Systems with NRTL, Electrolyte-NRTL, and UNIQUAC

Characterization of liquid-liquid equilibrium (LLE) in system contai ing ionic liquids (ILs) is important in evaluating ILs as candidates for replacing traditional extraction and separation solvents. Though an increasing amount of experimental LLE data is becoming available, comprehensive coverage of ternary liquid-phase behavior via experim ental observation is impossible. Therefore, it is important to model the LLE of m ixtures containing ILs. Experimental binary and ternary LLE data involving ILs can be correlated using standard excess Gibbs energy models. However, the predictive capability of these models in this context has not been widely studied. In this paper, we study the effectiveness wit h which excess Gibbs energy models can be used to predict ternary LLE solely from binary measurements. This is a st ringent test of the suitability of various models for describing LLE in sy stems containing ILs. Three different excess Gibbs free energy models are evaluated: the NRTL, UNIQUAC and electrolyteNRTL (eNRTL) models. In the case of eNRTL, a new formulation of the model is used, based on a symmetric reference state. To our knowledge, this is the first time that an electrolyte excess Gibbs energy model has been formulated for and applied to the modeling of multicomponent LLE for mixtures involving ILs. Ternary systems (IL, solvent, cosolvent) exhibiting experimental phase diagrams of various types have been chosen from the literature for comparison with the predictions. Comparisons of experimental and predict ed o anol-water partition coefficients are also used to evaluate the models studied.
Patterns of Comorbidity Among Girls With ADHD: A Meta-analysis.

CONTEXT
Although children with attention-deficit/hyperactivity disorder (ADHD) are at elevated risk for comorbid psychopathology, the clinical correlates of ADHD in girls are far less understood relative to boys, despite ADHD being one of the most common childhood disorders in girls.


OBJECTIVE
To meta-analytically summarize rates of comorbid internalizing (anxiety, depression) and externalizing (oppositional defiant disorder [ODD], conduct disorder [CD]) psychopathology among girls with and without ADHD.


DATA SOURCES
Literature searches (PubMed, Google Scholar) identified published studies examining comorbid psychopathology in girls with and without ADHD.


STUDY SELECTION
Eighteen studies (1997 participants) met inclusion criteria and had sufficient data for the meta-analysis.


DATA EXTRACTION
Odds ratios for each comorbid disorder were calculated from available data. Demographic (eg, age, race/ethnicity) and study characteristics (eg, referral source, diagnostic method) were also coded.


RESULTS
Compared with girls without ADHD, girls with ADHD were significantly more likely to meet Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for each comorbid disorder assessed. Relative odds were higher for externalizing (ODD: 5.6×; CD: 9.4×) relative to internalizing disorders (anxiety: 3.2×; depression: 4.2×). Meta-regression revealed larger effect sizes of ADHD on anxiety for studies using multiple diagnostic methods, featuring younger children, and including clinic-referred (versus community-referred) girls; the effect of ADHD on ODD varied based on diagnostic informant.


LIMITATIONS
Findings were derived from cross-sectional studies, precluding causal inferences.


CONCLUSIONS
Girls with ADHD frequently exhibit comorbid externalizing and internalizing disorders. We discuss future research priorities and consider intervention implications for ADHD and comorbid psychopathology in girls.
Software Architecture Knowledge Management

Software architecture is a recognized and indispensable part of system development. Software architecture is often defined in terms of components and connectors, or the "high-level conception of a system". In recent years, there has been an awareness that not only the design itself is important to capture, but also the knowledge that has led to this design. This so-called architectural knowledge concerns the set of design decisions and their rationale. Capturing architectural knowledge is difficult. Part of it is tacit and difficult to verbalize. Like developers, software architects are not inclined to document their solutions. Establishing ways to effectively manage and organize architectural knowledge is one of the key challenges of the field of software architecture. This architectural knowledge plays a role during development, when architects, developers, and other stakeholders must communicate about the system to be developed, possibly in a global setting. It also plays a role during the evolution of a system, when changes are constrained by decisions made earlier.

Panel Data Models for Stock Returns: the Importance of Industries

We study the predictability of stock returns in a panel of individual stocks. Our econometric models can deal with unbalanced panel data, cross sectional correlation among prediction errors and industry specific time effects. We perform misspecification tests related to the cross industry heterogeneity and poolability. For a panel of 1216 US firms for the period 1985–2002 we find that industry effects are significant and interact with firm characteristics like size and momentum. This conclusion is robust to the estimation method, the data and the forecasting horizon. High expected returns are mostly related to the cash flow-to-price ratio and the analyst earnings revisions, somewhat to the momentum, but hardly to most valuation ratios. In-sample portfolio construction results in long-short portfolios with substantial abnormal returns.
