Probing Representations of Gymnastics Movements: A Visual Priming Study

In this study, we designed a visual short-term priming paradigm to investigate the mechanisms underlying the priming of movements and to probe movement representations in motor experts and matched controls. We employed static visual stimuli that implied or not human whole-body movements, that is, gymnastics movements and static positions. Twelve elite female gymnasts and twelve matched controls performed a speeded two-choice response time task. The participants were presented with congruent and incongruent prime-target pairs and had to decide whether the target stimulus represented a gymnastics movement or a static position. First, a visual priming effect was observed in the two groups. Second, a stimulus-response rote association could not easily account for our results. Novel primes never presented as targets could also prime the targets. Third, by manipulating three levels of prime-target relations in moving congruent pairs, we demonstrated that the more similar prime-target pairs, the greater the facilitation in target. Lastly, gymnastics motor expertise impacted on priming effects.
Ocorrência e controle subjetivo do stress na percepção de bancários ativos e sedentários: a importância do sujeito na relação "atividade fisica e saúde"

OCCURRENCE AND SUBJECTIVE CONTROL OF STRESS IN THE PERCEPTION OF ACTIVE AND SEDENTARY BANK CLERKS; THE SUBJECT'S IMPORTANCE IN THE RELATIONSHIP PHYSICAL ACTIVITY AND HEALTH. Author: Alexandro Andrade Adviser: Prof. Dr. Francisco A . P. Fialho The objective of this research is to verify how the bank clerks of a state bank in Florianópolis, identified as sedentary and active, they notice your lifestyle, your fitness and motor capacity, your work environment and family, the occurrence and the subjective control of the stress. In the first stage, the approach of the research was qualitative, through of applied of a interview semi structured, each of 16 bankers, 6 actives and 10 sedentary. It was used the analysis of the content and the technique of the " mirror ", developed in this study, for analysis o f the categories and the units of analysis. In the second stage, the approach was quantitative, applying a mixed questionnaire in 50 bank (20 actives and 30 sedentary), aiming at to quantify the variables structured in the first stage, applying the statistics descriptive, parametric and no-parametric. The results indicate important differences in the researched groups. The actives practice physical activity regularly, an active leisure and they consume a balanced diet, telling good health. The sedentary ones don't make physical activity, they prefer a relaxing leisure, they don't affirm alimentary control, telling problems of health. While the actives manifest to have good force, resistance, flexibility, aerobic resistance and capacity neuromuscular for the work, the sedentary group it describes compromising of these capacities. The anxiety level, tension, competitiveness and the perfectionism is high, significantly larger in the sedentary bank clerks. Contrarily, the ambition level is low. The work atmosphere is stressful, working up to 3 overtimes a
IL-6 and IL-8 Serum Levels Predict Tumor Response and Overall Survival after TACE for Primary and Secondary Hepatic Malignancies

While surgical resection represents the standard potentially curative therapy for liver cancer, transarterial chemoembolization (TACE) has evolved as a standard therapy for intermediate-stage hepatocellular carcinoma (HCC) as well as liver metastases. However, it is still not fully understood which patients particularly benefit from TACE. Cytokines represent a broad category of signaling molecules that might reflect concomitant inflammation as an adverse prognostic factor. Here, we evaluated the role of interleukin (IL)-6, IL-8, and CC-chemokine ligand (CCL)22 as biomarkers in the context of TACE treatment. Cytokine serum levels were analyzed by multiplex immunoassay in 54 patients (HCC: n = 44, liver metastases: n = 10) undergoing TACE as well as 51 healthy controls. Patients with primary and secondary liver cancer showed significantly elevated levels of IL-6 and IL-8 but not CCL22 compared to healthy controls. Interestingly, low pre-interventional levels of IL-6 and IL-8 were predictors for an objective response after TACE in binary logistic regression. In contrast, patients with high pre-interventional IL-6 and IL-8 serum levels not only poorly responded to TACE but had a significantly impaired overall survival. Serum levels of IL-6 and IL-8 represent promising biomarkers for patients undergoing TACE and might help to pre-interventionally identify patients who particularly benefit from TACE regarding objective treatment response and overall survival.
Pitch heights and contours of tones in weifang dialect: An experimental investigation

An experiment was conducted to investigate pitch heights and contours of tones in Weifang Dialect. Eight middle- aged native speakers of Weifang Dialect participated in the experimental fieldwork. Tone types and values described in Documentation of Weifang Dialect [1] were taken as a reference. Acoustic data, including duration and fundamental frequency (F0), were extracted by using a Praat script— ProsodyPro [2] to track the pitch heights and contours of each tone-syllable sequence in the stimuli. F0 values were normalized to Log-Z (LZ) scores for speakers' individual differences [3, 4]. Tone values extracted from the LZ scores were determined according to the five-scale annotation of tones [5]. Tones in Weifang Dialect were found 324, 52, 44, and 41 in the experiment in contrast to 213, 42, 55 and 21 in Documentation of Weifang Dialect. Syllable durations of the different tones were also examined and compared.
Maxillomandibular giant osteosclerotic lesions

Abstract Giant Osteosclerotic Lesions (GOLs) are a group of rarely reported intraosseous lesions. Their precise diagnosis is important since they can be confused with malignant neoplasms. Objective This retrospective study aimed to record and analyze the clinical and radiographic Giant Osteosclerotic Lesions (GOLs) detected in the maxillomandibular area of patients attending to our institution. Materials and Methods: Informed consent from the patients was obtained and those cases of 2.5 cm or larger lesions with radiopaque or mixed (radiolucid-radiopaque) appearance located in the maxillofacial bones were selected. Assessed parameters were: age, gender, radiographic aspect, shape, borders, size, location and relations to roots. Lesions were classified as radicular, apical, interradicular, interradicular-apical, radicular-apical or located in a previous teeth extraction area. Additionally, several osseous and dental developmental alterations (DDAs) were assessed. Results Seventeen radiopacities in 14 patients were found and were located almost exclusively in mandible and were two types: idiopathic osteosclerosis and condensing osteitis. GOLs were more frequent in females, and in the anterior and premolar zones. 94.2% of GOLs were qualified as idiopathic osteosclerosis and one case was condensing osteitis. All studied cases showed different osseous and dental developmental alterations (DDAs). The most common were: Microdontia, hypodontia, pulp stones, macrodontia and variations in the mental foramina. Conclusions GOLs must be differentiated from other radiopaque benign and malignant tumors. Condensing osteitis, was considered an anomalous osseous response induced by a chronic low-grade inflammatory stimulus. For development of idiopathic osteosclerosis, two possible mechanisms could be related. The first is modification of the normal turnover with excessive osseous deposition. The second mechanism will prevent the normal bone resorption, arresting the osseous breakdown process.
Drug-Resistant tuberculosis in Ethiopia: Characteristics of cases in a referral hospital and the implications

Background: Tuberculosis (TB) programs should design intervention strategies based on the sound knowledge of the existing local epidemiology and sociodemographic characteristics of drug-resistant-TB (DR-TB) cases. The aim of the study was to characterize the pulmonary multidrug-resistant (MDR) and rifampicin-resistant (RR) TB cases enrolled in a referral hospital at Addis Ababa, Ethiopia, called All Africa Leprosy, Tuberculosis, Rehabilitation and Training (ALERT) Hospital. Methods: We conducted a descriptive study based on retrospective review of medical records of 340 pulmonary MDR/RR-TB cases enrolled in ALERT Hospital from November 2011 to December 2016. To characterize the cases, we described the distribution of demographic and clinical characteristics. To compare the distribution of demographic and clinical characteristics between male and female cases, we used Pearson's Chi-squared test. Results: Males accounted for 52.9% of the 340 cases. Nine out of ten cases were in the age group of 15–44 years. Sputum acid-fast bacilli smear-positive and human immunodeficiency virus-coinfected cases constituted 63.7% and 18.1% of cases, respectively. The proportion of new cases increased through the years from nil in 2011 to 21.4% in 2016. Adult males above 24 years constituted more than three quarters (77.2%) of the total male cases, while adult females in this age group constituted 56.9%. The age distribution between male and female cases showed significant differences (P < 0.001). Conclusion: There is age disparity between male and female cases with high impact of MDR/RR-TB on productive adult male population. The transmission potential for DR-TB is also high in the community.
What You Say Your Strategy Is and Why It Matters: Natural Language Processing of Unstructured Text

This study explores how new text analysis tools can be used in strategic management research that examines unstructured textual data. We build on two established natural language processing (NLP) techniques, vector space models and topic modeling, to create text-based measures of several core constructs in strategy – namely strategic change, positioning, and focus. These techniques are applied to the entire sample of 52,392 business descriptions in 10-K annual reports from 1996 to 2016. Results show that these new methods produce innovative yet meaningful measures of firm strategy which open up previously unexplored avenues of research to strategy scholars. The study advances emerging strategy research utilizing text analysis methods, demonstrates that NLP techniques can overcome some of the limitations of traditional text analysis methods such as keyword counts and mapping analysis, and provides a template for how other machine learning techniques could be introduced into strategy.
APOL1 Nephropathy Risk Variants and Incident Cardiovascular Disease Events in Community-Dwelling Black Adults

Background: APOL1 renal risk variants are strongly associated with chronic kidney disease in Black adults, but reported associations with cardiovascular disease (CVD) have been conflicting. Methods: We examined associations of APOL1 with incident coronary heart disease (n=323), ischemic stroke (n=331), and the composite CVD outcome (n=500) in 10 605 Black participants of the REGARDS study (Reasons for Geographic and Racial Differences in Stroke). Primary analyses compared individuals with APOL1 high-risk genotypes to APOL1 low-risk genotypes in Cox proportional hazards models adjusted for CVD risk factors and African ancestry. Results: APOL1 high-risk participants were younger and more likely to have albuminuria at baseline than APOL1 low-risk participants. The risk of incident stroke, coronary heart disease, or composite CVD end point did not significantly differ by APOL1 genotype status in multivariable models. The association of APOL1 genotype with incident composite CVD differed by diabetes mellitus status (Pinteraction=0.004). In those without diabetes mellitus, APOL1 high-risk genotypes associated with greater risk of incident composite CVD (hazard ratio, 1.67; 95% confidence interval, 1.12–2.47) compared with those with APOL1 low-risk genotypes in multivariable adjusted models. This latter association was driven by ischemic strokes (hazard ratio, 2.32; 95% confidence interval, 1.33–4.07), in particular, those related to small vessel disease (hazard ratio, 5.10; 95% confidence interval, 1.55–16.56). There was no statistically significant association of APOL1 genotypes with incident CVD in subjects with diabetes mellitus. The APOL1 high-risk genotype was associated with higher stroke risk in individuals without but not those with chronic kidney disease in fully adjusted models. Conclusions: APOL1 high-risk status is associated with CVD events in community-dwelling Black adults without diabetes mellitus.

This paper introduces the development of a system for a gunfire sound classification using a smartphone. The sound is detected using microphones connected to an embedded system to further process and transform it into a digital format. Artificial Neural Network is adopted as a recognition process for classifying the gunfire sound in the interested sound group. It is found that 6 different types of gunfire sound can be classified correctly with the proposed system. Also, the system can differentiate other sounds from the interested gunfire sounds. This proposed classifying system is expected to help analyze and find the source of the gun, in time, in the patrol area even better.

Overexpression of glypican-3 is a predictor of poor prognosis in hepatocellular carcinoma

Background: Glypican-3 (GPC3) has been widely recognized in the progression of liver tumors for several years. The relationship between overexpression of GPC3 and the poorer prognosis of patients with hepatocellular carcinoma (HCC) was performed by 2 meta-analyses. However, there were also some latest literatures that indicated different conclusions distinctly. It is necessary for us to carry out a meta-analysis by adding the latest data from current studies to explore the correlation between GPC3 and prognostic value in HCC. Methods: We conducted a meta-analysis including a total of 14 studies to assess the potential prognostic significance of GPC3 expression for overall survival (OS) and disease-free survival (DFS). The expression of GPC3 was assessed by immunohistochemistry. Results: Fourteen studies with 2364 patients were incorporated in the meta-analysis. The combined hazard ratios (HRs) revealed that the overexpression of GPC3 could forecast a poor OS [n = 2233 in 12 studies, HR = 1.40, 95% confidence interval (95% CI): 1.07–1.85, Z = 2.42, P = . 02] and DFS (n = 1308 in 10 studies, HR = 1.61, 95% CI: 1.13–2.30, Z = 2.63, P = .008) in HCC patients. Subgroup treated by hepatectomy indicated that the pooled HR of OS was 1.43 (95% CI: 1.01–2.01, P = .04) and the combined HR of DFS was 1.59 (95% CI: 1.09–2.31, P = .02). The pooled odds ratios (ORs) showed that high GPC3 expression was also extensively associated with worse tumor differentiation, later tumor stage, presence of vascular invasion, and hepatitis B virus (HBV) infection. Subgroup analyses for GPC3 on HCC OS based on the studies categorized by regions, follow-up period, and sample size were also conducted. Conclusion: The meta-analysis indicated that overexpression of GPC3 was significantly associated with poor prognosis in patients with HCC.
Geochemical and Microbiological Evidence for Microbial Methane Production in Deep Aquifers of the Cretaceous Accretionary Prism

Accretionary prisms are thick layers of sedimentary material piled up at convergent plate boundaries. Large amounts of anaerobic groundwater and methane (CH4) are contained in the deep aquifers associated with accretionary prisms. In order to identify microbial activity and CH4 production processes in the deep aquifers associated with the Cretaceous accretionary prism in Okinawa Island, Japan, we performed geochemical and microbiological studies using anaerobic groundwater and natural gas (mainly CH4) samples collected through four deep wells. Chemical and stable hydrogen and oxygen isotope analyses of groundwater samples indicated that the groundwater samples obtained from each site originated from ancient seawater and a mixture of rainwater and seawater, respectively. Additionally, the chemical and stable carbon isotopic signatures of groundwater and natural gas samples suggested that CH4 in the natural gas samples was of a biogenic origin or a mixture of biogenic and thermogenic origins. Microscopic observations and a 16S rRNA gene analysis targeting microbial communities in groundwater samples revealed the predominance of dihydrogen (H2)-producing fermentative bacteria and H2-utilizing methanogenic archaea. Moreover, anaerobic cultures using groundwater samples suggested a high potential for CH4 production by a syntrophic consortium of H2-producing fermentative bacteria and H2-utilizing methanogenic archaea through the biodegradation of organic substrates. Collectively, our geochemical and microbiological data support the conclusion that the ongoing biodegradation of organic matter widely contributes to CH4 production in the deep aquifers associated with the Cretaceous accretionary prism.
Management of complications of acute pancreatitis

Purpose of review Acute pancreatitis can result in a number of localized complications such as pancreatic pseudocysts, walled-off pancreatic necrosis (WON), and disconnected pancreatic duct syndrome (DPDS). The management of these conditions has evolved over the past three decades such that minimally invasive endoscopic drainage and debridement methods are now the favored, first-line approach. This article will review the latest developments and controversies regarding the endoscopic management of these conditions. Recent findings For patients with pancreatic pseudocysts, it remains to be clear what the role of routine ERCP is in this population. For WON, it is clear that when expertise is available, a minimally invasive approach may be the most suitable option. There is a growing literature raising concern about LAMS-associated bleeding in this group, however. Alterations in LAMS placement and stent dwell time may reduce this risk. Lastly, recognition of the DPDS is an important factor that needs to be recognized whenever present, as these patients will require a long-term management strategy and may require multimodality intervention. Summary Despite the development of new endoscopic techniques and dedicated devices for managing pancreatic fluid collections and disconnected pancreatic duct syndrome, a number of issues remain unresolved in terms of best practice methods.
Lagrange-Polynomial-Interpolation-Based Keystone Transform for a Passive Radar

In this paper, we address the problem of target's range migration in passive bistatic radar exploiting long coherent integration times with fairly wideband signals of opportunity. We resort to the well-known keystone transform (KT) to compensate for the range walk effect and to take advantage of a higher coherent integration gain against targets with nonnegligible radial velocity. Specifically, an efficient implementation of the KT is proposed, based on the Lagrange polynomial interpolation, in order to reduce the computational load of the method that mostly depends on the required slow-time interpolation stage. The analysis conducted against simulated data shows that the conceived approach allows us to achieve theoretical performance, while further reducing the KT complexity with respect to alternative solutions based on cardinal sine functions or chirp-Z transforms. Moreover, the application against experimental datasets collected by a DVB-T-based passive radar proves the practical effectiveness of the proposed algorithm and highlights its suitability for real-time air traffic surveillance applications.
Effect of conventional and microwave glazing on surface roughness of metal ceramics: An atomic force microscopy analysis

Purpose: This study investigated and compared the surface roughness achieved by glazing porcelain samples in a conventional and a microwave oven. Materials and Methods: Two commercial brands of metal ceramics were used, VITA VMK MASTER and IPS CLASSIC. Sixty samples were fabricated, 30 for each type of ceramic. The samples were sintered in the conventional oven and hand-polished to remove any irregularities. Samples (n = 10) from each type of ceramic were further divided into three groups as follows: hand-polished (Group A), conventional oven glazed (Group B), and microwave glazed (Group C). Each specimen was evaluated for surface roughness by atomic force microscope. Data were statistically analyzed using two-way analysis of variance (ANOVA) and Tukey's post hoc test (a = 0.05). Results: Two-way ANOVA indicated a highly significant difference in surface roughness based on the type of glazing (P < 0.001), there was a significant difference based on the metal ceramics (P = 0.002). There was also a significant interaction between the type of glazing and metal ceramics (P = 0.009). The images obtained from the atomic force microscope corroborated the measured values. Conclusions: All the results indicate that microwave glazing can be a feasible option for glazing porcelain specimens. It was concluded that surface topography is influenced by surface treatment and microwave glazed ceramic is superior to conventional oven glazed ceramic and hand-polishing showed greater surface roughness when compared to glazing. IPS CLASSIC ceramic showed relatively smooth surface when compared to VITA VMK MASTER irrespective of the surface treatment.
Chaotic time series prediction with functional link extreme learning ANFIS (FL-ELANFIS)

In this paper, a combined model Functional Link Extreme Learning ANFIS is proposed to predict chaotic systems. The model incorporates the concept of functional link neural network (FLNN) to the Extreme Learning ANFIS providing enhanced performance results. The premise parameters are randomly selected subjected to certain constraints and the consequent parameters are trained using Moore-Penrose inverse providing good prediction results in a short time. The combined model is used for multi-step-ahead prediction and simulation results shows that the model obtains improved performance when compared with other models.
A numerical approximation method for RSS-based user positioning in distributed massive MIMO

We consider user positioning in distributed massive multiple-input multiple-output (MIMO) systems based on uplink received signal strength (RSS) recorded at the base station. We take a machine learning approach, wherein, we train a Gaussian process regression (GP) model with uplink RSS vectors for several known training user locations and use the trained GP model for predicting locations of test users from their uplink RSS vectors. When the training RSS is noise-free and the test RSS is noisy due to shadowing from the wireless channel, we observe that the conventional GP method provides unrealistically small 2σ error-bars on the predicted locations. To address this shortcoming, we propose NAGP — a numerical approximation based GP method which employs averaging over Monte-Carlo samples to improve the 2σ error-bar estimates. Simulation studies confirm the superior performance offered by the NAGP method.
