Frailty in Older Brazilians – FIBRA-RJ: research methodology on frailty, cognitive disorders and sarcopenia

The frailty syndrome is associated with adverse events, including disability and death. In Brazil, it is a poorly understood condition. The objective of this report was to present the methodology used in FIBRA-RJ, the Rio de Janeiro section of the Frailty in Brazilian Older People (FIBRA-BR) study, which was developed to overcome this gap in knowledge. The baseline study (first phase) was carried out in 2009-2010. The sample was composed of 847 individuals (65 years old and older, customers of a health care plan) randomly selected and stratified by sex and age. This phase estimated the prevalence of frailty and its associated factors. The second phase (2010-2011) estimated the prevalence of dementia and its associated factors, and the third phase (2012-2013) estimated the prevalence and incidence of sarcopenia/sarcopenic obesity and its associated factors. The prevalence of frailty was 9.1%, and it was associated with age, education, cognition, negative health perception, comorbities, and deteriorating functionality. The prevalence of dementia was 16.9%, and it was associated with age and illiteracy. In total, eleven articles, four dissertations, and two theses were published; seven other theses and dissertations are in progress, which will include the results of phase 3. The FIBRA-RJ has reported descriptive studies with well-known limitations associated with reverse causality. Phase 3 will enable us to study incidences, and the predictive validity of biomarkers vis-à-vis mortality, adverse health outcomes, and the use of health services. The FIBRA-RJ study represents an advance in the understanding of the health problems that affect the aging Brazilian population.
Thermoluminescent properties of Dy doped calcium borate based glass for dose measurement subjected to photon irradiation

This study presents the thermoluminescent (TL) dosimetric properties of calcium borate glass with various dopant concentration of dysprosium (Dy). Calcium borate glass is a new potential material to be used in radiation measurement with absorption coefficient that is close to human bone. A series of glasses based on chemical equation xCaO-(100-x) B2O3 system, x = 0.1, 0.2, 0.3, 0.4, 0.5 (0< x <100) % weight have been prepared by melt quenching method. The X-ray diffraction analysis of glass samples were carried out and the result showed a broad peak, which confirmed the amorphous nature of the glass. The 70B2O3-30CaO glass sample was found as the most stable among other glass samples studied. Present work focuses on 70B2O3-30CaO glass of (0.01-0.4) mol% Dy-doped in order to investigate the thermoluminescence (TL) properties, in particular, dose-response and fading. The glass samples were irradiated to dose range of 0.5-4.0 Gy subjected to 6MV photon irradiations of LINAC Primus MLC 3339. TL response of 0.3 mol% Dy-doped 70B2O3-30CaO glass was found to produce highest response, with good linear dose- response relationship.
Foundations of Incomplete Contracts

In the last few years, a new area has emerged in economic theory, which goes under the heading of 'incomplete contracting'. However, almost since its inception, the theory has been under attack for its lack of rigorous foundations. In this paper we evaluate some of the criticisms that have been made of the theory, in particular, those in Maskin and Tirole (1998a). In doing so, we develop a model that provides a rigorous foundation for the idea that contracts are incomplete.
Micromeria thymifolia Essential Oil Suppresses Quorum-sensing Signaling in Pseudomonas aeruginosa

The chemical composition, antimicrobial and antiquorum sensing activity of the essential oil of Micromeria thymifolia (Scop.) Fritsch were investigated. Limonene, piperitone epoxide and piperitenone epoxide were found as the main constituents using a gas chromatography-mass spectrometry technique. In vitro antimicrobial activity of the oil was tested against six bacterial and seven fungal strains and high antimicrobial potential was noticed. Minimum inhibitory concentration varied from 0.031 mg/mL to 0.5 mg/mL for bacterial and 0.062 mg/mL to 0.5 mg/mL for fungal strains. The antiquorum properties of the essential oil were evaluated on Pseudomonas aeruginosa PAO1. The oil was tested at subMIC concentrations for anti-quorum sensing activity. The analyses on quorum-sensing functions have been carried out by evaluating twitching and swarming of bacterial cultures and the total amount of pyocyanin production produced by P. aeruginosa. This study showed that M. thymifolia essential oil exhibited antiquorum sensing activity and may be used as an antipathogenic drug.
Comparing image-based point clouds and airborne laser scanning data for estimating forest heights

Abstract: Accurate and updated knowledge of forest tree heights is fundamental in the context of forest management. However, measuring canopy height over large forest areas using traditional inventory techniques is laborious, time-consuming and excessively expensive. In this study, image-based point clouds produced from stereo aerial photographs (AP) were used to estimate forest height, and compared to Airborne Laser Scanning (ALS) data. We generated image-based Canopy Height Models (CHM) using different image-matching algorithms (SGM: Semi-Global Matching; eATE: enhanced Automatic Terrain Extraction), which were compared with a pure ALS-derived CHM. Additionally, plot-level height and density metrics were extracted from CHMs and used as explanatory variables for predicting the Lorey’s mean height (LMH), which was measured at 296 reference points on the ground. CHMSGM and CHMALS showed similar results in predicting LMH at sample plot locations (RMSE% = 8.54 vs. 7.92, respectively), while CHMeATE had lower accuracy (RMSE% = 13.23). Similarly, CHMSGM showed a lower normalized median absolute deviation (NMAD) from CHMALS (0.68 m) compared to CHMeATE (1.1 m). Our study revealed that image-based point clouds using SGM in the presence of high-resolution ALS-derived digital terrain model (DTM) provide comparable results with ALS data, while the performance of image-based point clouds using eATE is poorer than ALS for forest height estimation. The findings of this study provide a viable and cost-effective option for assessing height-related forest structural parameters. The proposed methodology can be usefully applied in all those countries where AP are updated on a regular basis and pre-existing historical ALS-derived DTMs are available.
Tg as an index of conversion in PMDI-impregnated wood

It is well established that the glass transition temperature (Tg) is a sensitive measure of cure in neat thermosets. As cure advances, network mobility declines and the Tg rises in a systematic fashion. This study sought to determine if such a relationship exists for polymeric isocyanate adhesives (pMDI) cured in the presence of wood. Yellow-poplar (Liriodendron tulipifera) specimens were impregnated with neat pMDI and then isothermally cured for various periods in two different differential scanning calorimeters (DSCs). After this isothermal cure period, the Tg and residual heat of cure were determined. These thermal scans were performed using either constant (conventional) or modulated (MDSC) heating rates. For both methods, the degree of resin cure varied significantly under identical isothermal curing conditions; nevertheless a strong relationship was found between the degree of resin cure and the associated Tg. While the conventional DSC method yielded slightly improved sensitivity and reproducibility, results from both methods compared favorably.
Intergenerational Wealth Mobility and the Role of Inheritance: Evidence from Multiple Generations

This study estimates intergenerational correlations in mid-life wealth across three generations, and a young fourth generation, and examines how much of the parent-child association that can be explained by inheritances. Using a Swedish data set we find parent-child rank correlations of 0.3-0.4 and grandparents-grandchild rank correlations of 0.1-0.2. Conditional on parents' wealth, grandparents' wealth is weakly positively associated with grandchild's wealth and the parent-child correlation is basically unchanged if we control for grandparents' wealth. Bequests and gifts strikingly account for at least 50 per cent of the parent-child wealth correlation while earnings and education are only able to explain 25 per cent.
Potency of an inactivated influenza vaccine prepared from A/duck/Mongolia/245/2015 (H10N3) against H10 influenza virus infection in a mouse model

The H10N8 influenza virus became a threat to public health when cases of fatal infections were identified in China in 2013 and 2014. Thus, genetic and antigenic characterization of H10 influenza viruses and development of an appropriate vaccine are essential to prepare for a future pandemic by H10 influenza viruses. However, current information regarding these properties of H10 influenza viruses circulating in birds is limited. In this study, genetic analysis of H10 influenza viruses revealed that the viruses recently circulating in wild birds in East Asia are genetically close to human H10N8 influenza viruses. Furthermore, the antigenicity of H10 influenza viruses was stable among the viruses circulating in birds. An inactivated vaccine was prepared from A/duck/Mongolia/245/2015 (H10N3), which is genetically and antigenically close to the human H10 influenza viruses. The vaccine induced sufficient neutralizing antibodies against homologous and heterologous viruses in mice. The inactivated vaccine induced protective immunity sufficient to reduce the impact of challenges with A/ duck/Hokkaido/W87/2007 (H10N2), which is pathogenic strain in mice. This study demonstrates that the inactivated whole virus particle vaccine prepared from viruses isolated from wild birds would be useful against a future pandemic influenza by H10 influenza viruses.

This study reports new discover of another Korean species E. musashinus (Tsuneki). This species was described based on male, and the female has been still unknown. With comparison of partial mitochondrial cytochrome c oxidase I gene sequences, the sex-association of this species is established, the Korean specimens of both sexes completely identical in their sequences targeted. Herein the female description of E. musashinus is presented for the first time. A key to the Korean species, as well as diagnosis and digital images are provided.
Over-expression of xylanolytic -glucuronidase from Thermotoga maritima in the pHsh system of Escherichia coli for the production of xylobiose from xylan

The GH67∝-glucuronidase encoded by aguA of Thermotoga maritima is one of the most thermostable ∝- glucuronidases described to date and thus has considerable potential in industrial application. The enzyme was higher expressed by using the novel pHsh expression vector than in pET vector in Echerichia coli. The site directed mutations changed codons for the first two arginines, a leucine and a proline in the 5’ flanking region of aguA to CGU, CUG and CCG respectively, resulted in a maximum activity of 7.1 U mg-1 in pHsh system. The results of calculation using MFOLD showed the introduction of replacement of the nucleotides encoding the N-terminal region of the protein by optimizing rare codons based on reducing the mRNA secondary structures in TIR is a useful approach to increase the expression level of heterologous proteins in E. coli cells. The ∝-glucuronidase of T. maritima was clearly able to remove 4-O-methylglucuronic acid groups from polymeric xylan and its fragment oligosaccharides. The enzyme acts synergistically with xylanase and beta-xylosidase in the hydrolysis of birchwood xylan and 4-O-methyl-D-glucuronoxylan. Enzymatic hydrolysis of corncob xylan examined by HPLC showed that more xylobiose was produced by xylanase hydrolysis in the presence of ∝- glucuronidase.

ASSOCIATION RULE MINING FOR GENE EXPRESSION DATA

Microarray technology has created a revolution in the field of biological research. Association rules can not only group the similarly expressed genes but also discern relationships among genes. We propose a new row-enumeration rule mining method to mine high confidence rules from microarray data. It is a support-free algorithm that directly uses the confidence measure to effectively prune the search space. Experiments on Leukemia microarray data set show that proposed algorithm outperforms support-based rule mining with respect to scalability and rule extraction.

Buying and selling in Word Grammar

The paper explores in some detail the semantics of the verbs which Fillmore classifies as 'commercial transaction' verbs: BUY, SELL, CHARGE, PAY, SPEND and COST. It shares Fillmore's belief that these meanings must be defined in terms of general semantic frames, but (like Lawler) it argues that more than one such frame is involved. In addition to the frame for Commercial transaction we need to invoke Trading, Consuming, Using, Giving and Getting, which interact to define the meanings of these verbs (and of course many others). The analysis is formalised in terms of Word Grammar theory, and assumes that each 'frame' is a concept represented as a node in a network of relations. The paper also considers the theoretical status of semantic relations (especially participant roles), and shows that these can be defined within the analysis through the network. One relation may be defined in terms of another either by being an example (in the 'isa' relation) of the other, or by sharing the same terms as the other.
Adsorption Enthalpy Calculations of Hydrogen Adsorption at Ambient Temperature and Pressures Exceeding 300 bar

Hydrogen adsorption isotherms were measured at ambient temperature to pressures exceeding 300 bar for three benchmark adsorbents: two metal-organic frameworks, Cu3(btc)2 (btc = 1,3,5-benzenetricarboxylate) and Zn4O(btb)2 (btb = 1,3,5-benzenetribenzoate), and the activated carbon MSC-30. The Dubinin-Astakhov model was applied to calculated absolute adsorption isotherms as a function of the fugacity to determine the adsorption enthalpy at ambient temperature. Comparisons of the calculated enthalpies and the surface excess concentration (excess adsorption per square meter of surface) show that Zn4O(btb)2 has an adsorption enthalpy comparable to MSC-30, but that the spacing between adsorbed molecules is much larger.
Portfolio Quality and Mutual Fund Performance

This study investigates how the quality of stocks owned by mutual funds affects the performance of those funds during 2000–2009. The quality of a stock is positively related to its size, while quality is inversely related to volatility. Evidently, stocks in the lowest quality decile perform particularly poorly amidst volatile market conditions with a mean monthly Daniel, Grinblatt, Titman and Wermers (DGTW) alpha 1.93% [25.73% per annum (pa)] less than high-quality stocks. Furthermore, funds which hold the lowest quality stocks exhibit substantial underperformance, particularly during market downturns, with funds in the lowest decile of quality incurring a mean monthly DGTW alpha 0.96% (12.14% pa) lower than their higher quality counterparts. Interestingly, we discover a trend to funds investing in higher quality stocks over time.
A no-reference video quality metric by using inter-frame encoding characters

Macro-block (MB) in DCT domain which contains the temporal and spatial information of video is a good video quality estimator in both encoding and transmission phase. Furthermore, MBs encoded by block-based coding standards can be obtained easily in bit-stream with a low time-complexity algorithm. Even so, this parameter is rarely used in video quality estimation under lossy network. So the major contribution of this paper can be concluded as it imports information from MBs of inter-frame encoded frames into video quality prediction and proposes a universal no-reference video quality metric over wireless networks which is named as Inter-frame Video Quality Metric (IEVQM). In detail, IEVQM analyze the impacts of both encoding and channel conditions to the video quality degradation by using motion vector and residual error from received P-frame and/or B-frame. Through extensive experiments and human subjective tests, we show that IEVQM demonstrate high correlation with Mean Opinion Score (MOS) for unknown video sequences both in distributed loss and burst loss situation (higher than 0.81).
IN VITRO APPROACHES ON THE DEVELOPMENT AND PROLIFERATIVE GROWTH OF INDUCING CALLUS FROM SOMATIC EXPLANTS OF HOT CHILI PEPPER (C. ANNUUM L. CV. PINTEA AND THE CV. DE CAYENNE)

Starting from the fact that synthesis and accumulation of secondary metabolites can be stimulated by in vitro cell culture from somatic tissues, the purpose of this study was to obtain biologically active substances from callus cell proliferation of varieties of hot chili pepper, like Pintea and De Cayenne genotype (C. annuum L.). Somatic explants taken after 21 days from the regenerated plantlets from germinated seeds in aseptic in vitro conditions, like hypocotyls, cotyledons, young leaves and apex were inoculated on several variants of hormonal combinations, added to the recipe of basal Murashige and Skoog (1962) culture medium. For the tested variants we used phytohormones, like auxins (NAA and 2.4-D) and cytokinins (kinetin) in concentrations ranging from 0.5 mg/L for kinetin and 0.3-1.0 mg/L for NAA and 2.4 D. The best results on the active growth of callus, were obtained for Pintea variety when there were utilized the cotyledons and apex (100%) and in the case of young leaves, the result was 58% on media supplemented with kinetin 0.5 mg/L . Comparing with this genotype, for explants of De Cayenne variety cultivated on the same combination of tested culture medium (MS supplemented with 0.5 mg/L kinetin), the results of 100% were obtained only at the apex level and for the other types of tested somatic explants, the values recorded was 94% in the case of young leaves and only 55% for cotyledons.
The clinician–patient working alliance: is it a significant predictor of psychiatric medication adherence in a sample of recently released parolees?

ABSTRACT Persistent psychiatric symptoms can serve as a major barrier to the successful reintegration of parolees with mental illness. Thus, it is important to identify factors that might impact their mental health recovery, such as low adherence to their treatment regimen. The strength of the clinician/patient working alliance has been found to be significantly associated with psychiatric medication adherence in prior research, but this relationship has not been assessed in a parolee population. Logistic regression analysis was used to determine if patient-rated working alliance was a significant predictor of low psychiatric medication adherence while taking into account alcohol/illegal drug use, age, and ethnicity in a sample of recently released parolees with mental illness (N = 49). Patient-rated working alliance, age, and ethnicity were not significant predictors of low adherence. Alcohol/illegal drug use during the follow-up period was associated with a significantly increased likelihood of meeting the criteria for low medication adherence (OR = 8.36; 95% CI = 1.60, 43.66). While working alliance was not found to be a significant predictor of medication adherence in this study, further research is needed to examine how substance misuse impacts the clinician–patient working alliance in this population.
Exploring the use of co-change clusters in software comprehension tasks

Feature-oriented software development (FOSD) is a paradigm that can be used, among others, to structure a software system around the feature concept that can represents small functionalities and non-functional requirements. Besides their role in software structure, FOSD enables the activation and deactivation of individual features in a given configuration of the software. This advantage can be useful in scenarios where the variability of the software is required. On the other hand, the adoption of FOSD can be done for an existing software system, thus, becomes necessary to apply some reverse engineering technique to extract features from a legacy code base, and also the mapping between these features and their implementations. This dissertation presents a new approach to aid in the reverse engineering activity, that relates historical data from issue tracking systems and source-code changes. The approach relies upon Mining Software Repositories (MSR) techniques, specifically the clustering based on co-evolutionary dependencies between source-code elements, which leads to the discover of co-change clusters. Thus, the goal of this work is to discover the properties of the co-change clusters that can be useful in a feature extraction process. Specifically, a set of terms, associated with the clusters, which reveal concepts that can help to identify features. According to the study results, co-change clusters have no advantage when used as a modular unit, but can reveal new dependencies that is hidden to the developer. They also show that the co-change clusters have conceptual cohesion, and can be used to extract concepts and the terms associated with them. In the end, the concepts extracted from co-change clusters can be used to build a mapping from them and the source-code, and that can be used as a input seed list to feature expansion methods.
Overview of Real-Time Antivirus Scanning Engines

Malicious code is one of the biggest problems in the world of networks. There exist various methods and techniques stating that they protect user. For quite some time the most popular protection method against viruses was on-demand scans. Various attempts to implement on-access or real-time scanning mechanisms were either consuming too much valuable system resources such as memory or offering too little protection. In this article we review a number of open-source and patented methods of real-time antivirus scanning describing their methods of work, advantages and disadvantages. Such kind of research is needed in order to gather in one article and to demonstrate the methods and attempts to successfully implement real-time scanning mechanism and to overview this sphere of application development. In what direction could the next step in developing real-time antivirus scanners be made and what problems are common in such cases
