Physical performance and muscular status in sarcopenic elderly following exercise and dietary supplement

The aim of this study is to establish the effect of a functional and nutritional intervention on the physical performance and muscular state of elderly people with sarcopenia in Manizales, Colombia. 28 sarcopenic patients, aged between 60 and 85 years old, underwent evaluation before and after 12 weeks of nutritional intervention and aerobic and resistance exercises. The latter was-gradually increased, with a frequency of 3 days per week and for 3 months. Muscle mass was estimated by bioelectrical impedance analysis (BIA) and corroborated by dual x-ray absorptiometry. The gait speed and the short battery of physical performance (SPPB) complemented the diagnosis. People with sarcopenia improved significantly with the intervention in their physical functionality, shown by physical performance tests (SPPB), and in the calf circumference, with no significant increases in grip strength or muscle size. A 12-week intervention with nutritional supplements and physical training improved physical performance without increasing skeletal muscle mass or grip strength. These results reinforce the findings of other researchers and suggest the need to continue investigating the most effective of supplements and exercises as well as the time required to impact the study variables.
Using carbamide for preparing nitrogen-doped graphene hydrogels to enhance supercapacitor performance

ABSTRACT In this paper, nitrogen-doped graphene hydrogel (NGH) has been synthesised by chemically reducing aqueous graphene oxide (GO) solution in the presence of carbamide.Its nitrogen content reaches 8.97 at%. It exhibits a 3D porous network structure with pore sizes of about 2 to 4 μm comparable to the graphene hydrogel (GH) prepared without nitrogen source. Meanwhile, the NGH shows same hierarchical mesoporous structure with dominant pore size about 2–5 nm as the GH’s. Besides, its specific surface area (132.8 m2 g−1) is higher than that of the GH (122.9 m2 g−1). The NGH can deliver an enhanced specific capacitance of 199.80 F g−1 at 2 A g−1 compared to that of the GH (142.23 F g−1). In addition, the NGH can retain 62.6% of specific capacitance from 2 to 50 A g−1. The NGH also can maintain 97% of its initial specific capacitance after 20,000 cycles at 10 A g−1.
Human Activity Recognition from the Acceleration Data of a Wearable Device. Which Features Are More Relevant by Activities?

Data driven approaches for human activity recognition learn from pre-existent large-scale datasets to generate a classification algorithm that can recognize target activities. Typically, several activities are represented within such datasets, characterized by multiple features that are computed from sensor devices. Often, some features are found to be more relevant to particular activities, which can lead to the classification algorithm providing less accuracy in detecting the activity where such features are not so relevant. This work presents an experimentation for human activity recognition with features derived from the acceleration data of a wearable device. Specifically, this work analyzes which features are most relevant for each activity and furthermore investigates which classifier provides the best accuracy with those features. The results obtained indicate that the best classifier is the k-nearest neighbor and furthermore, confirms that there do exist redundant features that generally introduce noise into the classification, leading to decreased accuracy.

Classification of EEG-based single-trial motor imagery tasks using a B-CSP method for BCI

Classifying single-trial electroencephalogram (EEG) based motor imagery (MI) tasks is extensively used to control brain-computer interface (BCI) applications, as a communication bridge between humans and computers. However, the low signal-to-noise ratio and individual differences of EEG can affect the classification results negatively. In this paper, we propose an improved common spatial pattern (B-CSP) method to extract features for alleviating these adverse effects. First, for different subjects, the method of Bhattacharyya distance is used to select the optimal frequency band of each electrode including strong event-related desynchronization (ERD) and event-related synchronization (ERS) patterns; then the signals of the optimal frequency band are decomposed into spatial patterns, and the features that can describe the maximum differences of two classes of MI are extracted from the EEG data. The proposed method is applied to the public data set and experimental data set to extract features which are input into a back propagation neural network (BPNN) classifier to classify single-trial MI EEG. Another two conventional feature extraction methods, original common spatial pattern (CSP) and autoregressive (AR), are used for comparison. An improved classification performance for both data sets (public data set: 91.25%±1.77% for left hand vs. foot and 84.50%±5.42% for left hand vs. right hand; experimental data set: 90.43%±4.26% for left hand vs. foot) verifies the advantages of the B-CSP method over conventional methods. The results demonstrate that our proposed B-CSP method can classify EEG-based MI tasks effectively, and this study provides practical and theoretical approaches to BCI applications.
Space qualification of 5 to 8 GHz bandwidth, uncooled, extended InGaAs 2.2-micron wavelength, linear optical receivers

We have successfully tested 5 to 8 GHz bandwidth, uncooled, Extended InGaAs 2.2 μm wavelength, linear optical receivers, coupled with single mode fibers for 30 MeV Protons, Gamma rays, 1 GeV/n Iron ions, and 1 GeV/n Helium ions. These devices find multiple applications in outer-space for coherent rapid Doppler shift LIDAR, long wavelength gravitational wave sensing, as well as inter-planetary and Earth-to-Moon coherent communication links. Nine devices comprising of Extended InGaAs 2.2 μm PIN photodiode (PD) and GaAs transimpedance amplifiers (TIA), coupled with single mode fibers, were tested with 30 MeV protons, three each with fluence levels of 4.9 × 1010 cm-2 , 9.8 × 1010 cm-2, and 1.6 × 1011 cm-2 . Three more devices were tested using 1.4 ♦ 108 Helium ions/cm2 at 1 GeV/n over a six minute exposure for a dose of 20 rad (water). Three additional devices were exposed to 1 GeV/n Fe fluence of 2.8 × 105 ions/cm2 for half a minute delivering a dose of 6 rad (water). Another three Extended InGaAs PD and GaAs TIA fibered devices were tested using Cesium-137 gamma rays of 662 keV for 15 krad (water). Pre- and post-radiation results were measured for (1) dark current vs. voltage for the InGaAs photodiodes, (2) responsivity (quantum efficiency) for the photodiodes, (3) optical return loss for the photodiodes, (4) TIA drive current, (5) bandwidth of the PIN + TIA, (6) conversion gain of the PIN-TIA, and (7) Bit Error Ratio (BER) of the PIN-TIA for 10.709 Gbps NRZ-ASK signal. All devices were found to be fully functional at normal operating conditions and at room temperature. All these efforts will advance the Technology Readiness Level (TRL) of these devices by year 2020.
Effects of Titanium Curette, Air Polishing and Titanium Brush on Implant Surface Roughness Using Scanning Probe Microscopy

Background: In peri-implant mucositis and peri-implantitis, inflammation extends to peri-implant tissue, which is associated with bone loss and can cause implant failure. To regain peri-implant tissue health, debridement and cleaning of implant surface without damaging it must be performed prior to any other treatment. Thus, this study aimed to assess the effect of titanium curette, air polishing and titanium brush on implant surface roughness. Methods: In this in vitro, experimental study, 2 SNUC titanium implants with 6 mm diameter and 10 mm length were sectioned into 10 pieces. Implant pieces were randomly divided into 4 groups (n=5) for polishing with titanium curette, air polishing, titanium brush and no intervention (control group). Surface roughness was determined under a scanning probe microscope (SPM) by measuring Ra and Rz parameters. Data was analyzed using Kruskal-Wallis and Mann-Whitney tests at significance level (α) of 0.05. Results: Ra and Rz values of the four groups were not significantly different (P=0.002). Air polishing group showed the lowest surface roughness and titanium curette group showed the highest surface roughness followed by titanium brush group, compared to control group. Conclusions: Air polishing group showed the lowest surface roughness compared to control group but an appropriate debridement technique should be chosen based on the treatment chosen for periimplantitis.
Building and Construction Research in Malaysia: A Bibliometric Analysis

This paper presents a bibliometric analysis of building and construction research authored by researchers reporting an affiliation to institutions in Malaysia from years 2000 to 2015. The objectives are to identify the most productive research institutions and researchers, the research themes at these institutions, the output and impact of the research carried out and the most prolific authors. A search on the Scopus database identified 1,668 articles published during this period. The results indicate that research output was primarily from the five public research universities reflecting their privileged funding model and that output had increased rapidly in recent years. Topics of research were broad ranging from materials and structures in the engineering field, to the more conventional construction management and building science topics. Although numerous authors from Malaysia have high citation counts and h-indices, the overall impact of the research was low with many articles either published in low impact journals or received few citations. There is evidence of publication inflation where the increase in publication counts have not been matched by a comparable increase in citation counts. National innovation or research funding policies must rigorously address both the quantity and quality of research outputs to accurately assess impact.

Recursive Portfolio Selection with Decision Trees

A great proportion of stock dynamics can be explained using publicly available information. The relationship between dynamics and public information may be of nonlinear character. In this paper we offer an approach to stock picking by employing so-called decision trees and applying them to XETRA DAX stocks. Using a set of fundamental and technical variables, stocks are classified into three groups according to the proposed position: long, short or neutral. More precisely, by assessing the current state of a company, which is represented by fundamental variables and current market situation, well reflected by technical variables, it is possible to suggest if the current market value of a company is underestimated, overestimated or the stock is fairly priced. The performance of the model over the observed period suggests that XETRA DAX stock returns can adequately be predicted by publicly available economic data. Another conclusion of this study is that the implied volatility variable, when included into the training sample, boosts the predictive power of the model significantly.
Caracterização de Ordens Maximais dos Quatérnios visando a construção de reticulados

Nosso trabalho consiste na construção de reticulados algébricos a partir de uma determinada álgebra de quatérnios gerada de um corpo de números totalmente real [2]. Reticulados algébricos vem sendo utilizados na proposição de códigos para transmissão de sinais em canais com desvanecimento do tipo Rayleigh. Dado K um corpo de números, uma álgebra dos quatérnios A = (a, b)K sobre K é uma álgebra central simples de dimensão 4 com base {1, i, j, k} satisfazendo i2 = a, j2 = b e k = ij = −ji, onde a, b ∈ K\{0}. Seja R um anel com corpo de frações K. Uma R-ordem O em A é um subanel com unidade de A que é um R-módulo finitamente gerado tal que A = KO. Já uma ordem maximal M tem a propriedade de não estar propriamente contida em nenhuma outra ordem [2,3]. É posśıvel construir reticulados a partir de uma Ordem Maximal da Álgebra dos Quatérnios. Em particular, apresentamos resultados para corpos de números da forma
Parametric modeling of NIR and SWIR absorbance spectra for dye mixtures in fabrics using Gaussian functions

This study describes parametric modeling of near-infrared (NIR, 0.7-0.9 μm) and shortwave infrared (SWIR, 0.9-1.7 μm) absorbance spectra, which is for optimizing NIR-SWIR reflectance of dyed fabrics with respect to given illuminations and background environments. The parametric models are linear combinations of gaussian functions, which are for modeling dyes in fabric whose absorption spectra span the NIR/SWIR spectral range. In general, decomposition of an absorbance spectrum in terms of linear combinations of gaussain functions is not unique. This suggests investigatng what are optimal linear combinations of gaussian functions for modeling given spectra. Prototype modeling is applied to NIR/SWIR absorbing dyes, and their mixtures, in fabric samples, which consist of a cotton blend. The results of this study demonstrate parametric modeling using linear combinations of gaussian functions for simulating NIR/SWIR absorbance spectra, which are for variable dye and dye blend concentrations in fabrics.
Impact of reinforcing additives on the structure and performance of composite films based on regenerated cellulose from corn stalk pith

Cellulose was extracted from corn stalk pith (CSP) and used for fabricating hybrid composite films with acceptable physical properties. As reinforced additives, low contents of graphene oxide (GO) and black phosphorene (BP), both ranging from 0.05 to 0.15 wt%, were separately incorporated into the cellulose matrix in a ZnCl2 aqueous system. A series of the composites were prepared via a regeneration process. The as-prepared composites showed various properties depending largely on the additive content, manner of processing, and the type of additive used. GO and BP nanosheets were homogeneously dispersed in the regenerated cellulose (RC), smoothly forming the dense films. Crystalline structures of RC-based films were revealed to be cellulose-II, and in addition to GO-crosslinked RC samples (RC-GO), an increase in the additive dosage led to a decrement in the crystallinity index of blended films (RC/GO and RC/BP). At 0.15 wt% additive amount, the RC-GO possessed superior thermal stability, tensile strength, and Young’s modulus, increasing 7.8%, 190.2%, and 79.0%, respectively, while the RC/BP exhibited a 3.5 times improvement in the elongation at break.
Optimization of a Trachea Bioreactor Design and Cell Seeding Parameters for the Re-epithelialization of Tracheal Scaffolds: a CFD Approach

Successful re-epithelialization of de-epithelialized tracheal scaffolds remains a challenge for tracheal graft success. Currently, the lack of understanding of the bioreactor hydrodynamic environment, and its relation to cell seeding outcomes, serve as major obstacles to obtaining viable tracheal grafts. In this work, we used computational fluid dynamics to (a) re-design the fluid delivery system of a trachea bioreactor to promote a spatially uniform hydrodynamic environment, and (b) optimize the perfusion cell seeding protocol to promote a spatially uniform cell deposition. Results showed that the proposed design change achieves these design goals. Lagrangian particletracking simulations showed that low rotation rates provide more uniform circumferential and longitudinal patterns of cell deposition, while higher rotation rates only improve circumferential uniformity but bias cell deposition proximally. Validation experiments with BEAS-2B cells confirm that the model accurately predicts cell deposition but not cell attachment, suggesting the need for including biologically accurate cell-cell and cell-scaffold interaction mechanisms in the
Arms, hostages, and the importance of shredding in earnest: Reading the national security culture (II)

The social intervention of a text (not necessarily achieved at the time the text appears) is measured not by the popularity of its audience or by the fidelity of the socioeconomic reflection it contains or projects to a few eager sociologists, but rather by the violence that enables it to exceed the laws that a society, an ideology, a philosophy establish for themselves in order to agree among themselves in a fine surge of historical intelligibility. This excess is called: writing. Roland Barthes, Sade/FourierlLoyola
Bank asset transparency and credit supply

We employ the European Central Bank’s Loan-level Reporting Initiative as a shock to banks’ asset disclosures. We find that after the disclosure regulation, treatment banks raise more capital at cheaper rates and increase lending. Using novel survey data on small businesses, we also document that, in regimes with heightened bank disclosures, borrowers receive greater funding, conditional on their demand for credit. Furthermore, companies whose relationship banks provide asset disclosures start to borrow and invest more relative to firms from the same country and industry. Collectively, our inferences suggest that asset disclosures alleviate the capital market frictions that banks face and allow them to supply more credit to the real economy.
Stress intensity factor for small embedded cracks in weldments

In the present work, the stress intensity factor (SIF) of embedded small cracks placed at the weld toe is calculated by means of two procedures based on the Oore-Burns integral. In the first approach, the defect is considered as a circular disk and the SIF is evaluated by means of the Oore-Burns weight function. By taking advantage of a suitable change of variable, the singularity of the weight function on the crack border can be removed. In this way, the numerical evaluation of the SIF is possible without the use of specific integration algorithms, although the nominal stress field becomes singular when the crack approaches a V-sharpe notch. As an example, the obtained equations are applied to a defect located in the neighbourhood of a weld toe with an opening angle of 135 degrees under mode I loading. Subsequently, for a crack similar to a star domain with a border expressed by means of the Fourier series, the SIF is given by means of an explicit equation based on the Oore-Burns weight function.
