Six-Minute Walk Test: Oxygen Uptake and Distance Predicted

: Background: Maximum oxygen consumption is an indicator of cardiorespiratory ﬁtness. Aim: e purpose was, ﬁrst, to relate and compare the VO 2 max as the dependent variable with the estimated distance in the six-minute walk test (SMWT) as the independent variable in university students and, secondly, to relate the distance (dependent) with demographic and anthropometric variables (independents). Methodology: A correlational, descriptive, and quantitative study with a non-experimental design was conducted on 110 university students. In the study, basic anthropometry and vital signs were measured. A direct method of VO 2 max (Bruce test) on a treadmill was applied. en, the distance covered in the SMWT was evaluated with two equations available in the scientiﬁc literature. Diﬀerences between men and women were measured in the tests, the correlation between the distances estimated with VO 2 max and anthropometric variables, and repeated ANOVA measurement tests between VO 2 max and estimated distance were analyzed with the SPSS v.22 program ( p< 0.05). Results: Signiﬁcant correlations were found between VO 2 max and estimated distances ( p< 0.05) in the total sample, men and women, and in some cases, the distance correlated with gender, age, weight, height, and BMI ( p< 0.05). However, there were diﬀerences between VO 2 max and distances estimated in the SMWT ( p< 0.001). Conclusions: e VO 2 max measurement method is diﬀerent from the distance prediction equations, although they have a signiﬁcant relationship.
Diagnostic importance of pulmonary interleukin-1 beta and interleukin-8 in ventilator-associated pneumonia

Background Ventilator-associated pneumonia (VAP) is the most commonly fatal nosocomial infection. Clinical diagnosis of VAP remains notoriously inaccurate. We tested the hypothesis that significantly augmented inflammatory markers distinguish VAP from conditions closely mimicking VAP. Methods A prospective, observational cohort study in two university hospital intensive care units recruiting 73 patients with clinically suspected VAP, and a semi-urban primary care practice recruiting a reference group of 21 age- and sex-matched volunteers. Growth of pathogens at >10 4 colony forming units/ml bronchoalveolar lavage fluid (BALF) distinguished VAP from ‘non-VAP’. Inflammatory mediators were quantified in BALF and serum. Mediators showing significant differences between patients with and without VAP were analysed for diagnostic utility by receiver operator characteristic (ROC) curves.

Essex Finance Centre Working Paper Series Working Paper No 31 : 02-2018 Forecasting with High-Dimensional Panel VARs “

This paper develops methods for estimating and forecasting in Bayesian panel vector autoregressions of large dimensions with time-varying parameters and stochastic volatility. We exploit a hierarchical prior that takes into account possible pooling restrictions involving both VAR coefficients and the error covariance matrix, and propose a Bayesian dynamic learning procedure that controls for various sources of model uncertainty. We tackle computational concerns by means of a simulation-free algorithm that relies on an analytical approximation of the posterior distribution. We use our methods to forecast inflation rates in the eurozone and show that forecasts from our flexible specification are superior to alternative methods for large vector autoregressions.
Gene-Based Analysis in HRC Imputed Genome Wide Association Data Identifies Three Novel Genes For Alzheimer’s Disease

A novel POLARIS gene-based analysis approach was employed to compute gene-based polygenic risk score (PRS) for all individuals in the latest HRC imputed GERAD (N cases=3,332 and N controls=9,832) data using the International Genomics of Alzheimer’s Project summary statistics (N cases=13,676 and N controls=27,322, excluding GERAD subjects) to identify the SNPs and weight their risk alleles for the PRS score. SNPs were assigned to known, protein coding genes using GENCODE (v19). SNPs are assigned using both 1) no window around the gene and 2) a window of 35kb upstream and 10kb downstream to include transcriptional regulatory elements. The overall association of a gene is determined using a logistic regression model, adjusting for population covariates. Three novel gene-wide significant genes were determined from the POLARIS gene-based analysis using a gene window; PPARGC1A, RORA and ZNF423. The ZNF423 gene resides in an Alzheimer’s disease (AD)-specific protein network which also includes other AD-related genes. The PPARGC1A gene has been linked to energy metabolism and the generation of amyloid beta plaques and the RORA has strong links with genes which are differentially expressed in the hippocampus. We also demonstrate no enrichment for genes in either loss of function intolerant or conserved noncoding sequence regions.
Performance evaluation of Vehicular Ad Hoc Networks over high speed environment using NCTUns

Catala: Cada any aproximadament un milio dues-centes mil persones moren en accidents de transit. D'aquesta dada es despren que els accidents de transit son la quarta causa de mortalitat al mon. Degut a aixo, un gran nombre de governs i els majors fabricants de vehicles del mon estan invertint temps i diners en recerca i desenvolupament per millorar la seguretat a les carreteres. Amb aquest objectiu, apareix el concepte de VANET: Vehicular Ad-hoc NETwork. Una VANET esta basada en vehicles i estacions base intel·ligents que comparteixen informacio a traves de comunicacions inalambriques. Aquest intercanvi de dades podria tenir un gran impacte en la seguretat viaria i la qualitat en la conduccio pero a mes a mes seria una nova font d' entreteniment mobil. La millora en seguretat implicaria una reduccio en el nombre d'accidents i les comunicacions inalambriques usades en mobilitat permetrien una optimitzacio del transport. L'evolucio de les VANETs en els ultims anys i les seves aplicacions utils a les carreteres son les principals raons per dur a terme aquest projecte. El gran suport a aquest tipus de xarxes inalambriques sembla indicar que les VANETs son les xarxes del futur en entorns mobils. En relacio al projecte, el primer problema observat es que el protocol que s'usa especificament en VANETs (802.11p) nomes esta disponible en pocs simuladors de xarxa i esta en fase de desenvolupament. Per tant, la majoria de les funcions no estan implementades i aixo fa que el protocol no sigui madur. En consequencia, es va triar un protocol ampliament usat com es 802.11b per fer les proves en el simulador NCTUns. L? objectiu del projecte es avaluar el funcionament de VANETs usant el protocol 802.11b i el protocol d? encaminament AODV en un escenari d? autopista. Ajustant diferents parametres com el nombre de cotxes, la seva velocitat i el seu rang de cobertura es possible obtenir variacions en les mesures de perdues, throughput i retard extrem-a-extrem en la xarxa. El resultat final es que les mesures permeten saber quines son les comunicacions que es produeixen a la xarxa per cadascuna de les configuracions i la seva incidencia en les condicions de conduccio.

— Artificial Intelligence (AI) algorithms as decision support assist operators to choose appropriate decisions in naval missions. This article offers a decision support model to predict the path of a Maritime Surface Ship (MSS) in a dynamic environment by using Deep Reinforcement Learning (DRL). In this way, we suggest taking into account weather forecast and simplified static and mobile obstacles.
Bioinformatic Analysis of The Prognostic Value of A Panel of Six Amino Acid Transporters in Human Cancers

Objective: Solid tumor cells utilize amino acid transporters (AATs) to increase amino acid uptake in response to nutrient-insufficiency. The upregulation of AATs is therefore critical for tumor development and progression. This study identifies the upregulated AATs under amino acid deprived conditions, and further determines the clinicopathological importance of these AATs in evaluating the prognosis of patients with cancers. Materials and Methods: In this experimental study, the Gene Expression Omnibus (GEO) datasets (GSE62673, GSE26370, GSE125782 and GSE150874) were downloaded from the NCBI website and utilized for integrated differential expression and pathway analysis v0.96, Gene Set Enrichment Analysis (GSEA), and REACTOME analyses to identify the AATs upregulated in response to amino acid deprivation. In addition, The Cancer Genome Atlas (TCGA) datasets with prognostic information were assessed and employed to evaluate the association of identified AATs with patients’ prognoses using SurvExpress analysis. Results: Using analysis of NCBI GEO data, this study shows that amino acid deprivation leads to the upregulation of six AAT genes; SLC3A2, SLC7A5, SLC7A1, SLC1A4, SLC7A11 and SLC1A5. GSEA and REACTOME analyses identified altered signaling in cells exposed to amino acid deprivation, such as pathways related to stress responses, the cell cycle and apoptosis. In addition, Principal Component Analysis showed these six AAT genes to be well divided into two distinct clusters in relation to TCGA tumor tissues versus normal counterparts. Finally, Log-Rank analysis confirmed the upregulation of this panel of six AAT genes is correlated with poor prognosis in patients with colorectal, esophageal, kidney and lung cancers. Conclusion: The upregulation of a panel of six AATs is common in several human cancers and may provide a valuable diagnostic tool to evaluate the prognosis of patients with colorectal, esophageal, kidney and lung cancers.
A New Dynamic-Bias Measurement Setup for Nonlinear Transistor Model Identification

— In this manuscript, we present a new dynamic-bias measurement set-up and its application to the extraction of a nonlinear model for microwave field-effect transistors. The dynamic-bias technique has been recently proposed and relies on the use of low-and high-frequency vector-calibrated measurements acquired, for instance, by means of a large-signal network analyzer (LSNA). In this work, we propose a new and alternative technique to perform the dynamic-bias measurements, based on relatively low-cost instrumentation commonly available in microwave laboratories. The new acquisition system is composed by a 4-channel vector LF receiver (e.g., an oscilloscope) and a 1-channel HF scalar receiver (e.g., a spectrum analyzer), which replace the 8-channel vector receiver. Moreover, the proposed architecture greatly simplifies the measurement setup and the calibration procedure. As case study, a 0.25-µ m GaN HEMT is considered. Dynamic-bias measurements, carried out by means of the proposed measurement setup, are used for the identification of a nonlinear model of this device. Finally, the model is fully validated through comparison with time-domain harmonic load-pull measurements carried out at 5 GHz.
Control Architecture for Parallel-Connected Inverters in Uninterruptible Power Systems

In this paper, a control strategy for the parallel operation of three-phase inverters forming an online uninterruptible power system (UPS) is presented. The UPS system consists of a cluster of paralleled inverters with LC filters directly connected to an ac critical bus and an ac/dc forming a dc bus. The proposed control scheme comprises two layers: 1) a local layer that contains a “reactive power-to-phase droop” in order to synchronize the phase angle of each inverter and a virtual resistance loop that guarantees equal power sharing among inverters; and 2) a central controller that guarantees synchronization with an external real/fictitious utility, and critical bus voltage amplitude restoration. Improved transient and steady-state frequency, active, reactive, and harmonic power sharing, and global phase-locked loop resynchronization capability are achieved. Detailed system topology and control architecture are presented in this paper. Furthermore, a mathematical model was derived in order to analyze critical parameters effects on system stability. The proposed control approach has been validated by means of experimental results obtained for several case-study scenarios.
Do key audit matters (KAM) matter? Auditors’ perceptions of KAM and audit quality in Finland

Purpose: Key Audit Matters (KAM) in ISA 701 seek to enhance the value of the auditor’s report by increasing the transparency of how the audit was performed. This article examines how professional auditors themselves perceive the impact of KAM on audit quality and audit effectiveness. Design: Statistical analyses of an electronic survey of certified public auditors in Finland. Findings: Regarding the perceptions of KAM, we found two dominant views on auditing: quality and efficiency . In general, the respondents did not consider that KAM improve audit quality. However, auditors focusing on efficiency considered that KAM make the audit process more fluent. Further, the use of KAM may facilitate audit effectiveness and cooperation between auditors and managers. We also found three factors related to the KAM processes and auditing work: effectiveness , risks , and workload . Practical implications: Auditors may employ KAM to provide focus in their work. This facilitates balancing between the demands for added value while keeping the workload and audit risks at a tolerable level. Originality: This study contributes to the emerging literature on KAM as well as to the literature examining practitioner views of changes in auditing regulation. It is, as far as we know, the first study to report survey evidence on how certified public auditors themselves perceive KAM and the effects of KAM on audit work in an EU country context.

Volatility Information Difference between CDS and Option markets and the Cross Section of Option Returns

We examine the information content difference between credit and option markets by extracting volatilities from corporate CDSs (credit default swap) and equity options. The difference is positively related to future option returns. We rank firms based on the normalized volatility spread and analyze the returns for straddle portfolios. A zero-cost trading strategy that long (short) in the portfolio with the largest (smallest) spread generates a significant average monthly return, even after controlling for stock characteristics, traditional risk factors, and moderate transaction costs.
Inexact Newton methods with matrix approximation by sampling for nonlinear least-squares and systems

We develop and analyze stochastic inexact Gauss-Newton methods for nonlinear least-squares problems and inexact Newton methods for nonlinear systems of equations. Random models are formed using suitable sampling strategies for the matrices involved in the deterministic models. The analysis of the expected number of iterations needed in the worst case to achieve a desired level of accuracy in the first-order optimality condition provides guidelines for applying sampling and enforcing, with fixed probability, a suitable accuracy in the random approximations. Results of the numerical validation of the algorithms are presented.
Endovascular treatment of ruptured very small intracranial aneurysms: a systematic review and meta-analysis

Background: Endovascular treatment (EVT) is widely accepted for intracranial aneurysms due to its safety and efficacy. However, EVT of ruptured very small intracranial aneurysms (RVSIA) (3 mm) is still challenging and the risk-benefit ratio of EVT remains unclear. The aim of this study was to evaluate the safety and efficacy of EVT of RVSIA.Methods: We performed a systematic review and meta-analysis of the studies on EVT of RVSIA. Pooled prevalence rates were calculated for initial and follow-up complete occlusion rates (Raymond Roy Grade 1), recanalization, retreatment, long-term favorable outcome (modified Rankins scale score 0 to 2 or Glasgow Outcome Scale 4 or 5), procedure-related complications (coil herniation, thromboembolism, and intraprocedural re-rupture), and procedure-related mortality. Pooled odds ratios were calculated to compare these outcomes between simple coiling and stent-assisted coiling (SAC). Results: Of the 600 studies screened, 24 studies with a total of 1355 RVSIAs treated with EVT were included. The initial and follow-up complete aneurysm occlusion rates were 64% (95% confidence interval [CI]: 5274%) and 85% (95% CI: 7492%). The rates of recanalization and retreatment were 6% (95% CI: 310%) and 3% (95% CI: 24%). The favorable long-term follow-up outcome was observed in 91% (95% CI: 8993%) of patients. The rates of coil herniation, thromboembolism, and intraprocedural rupture were 2% (95% CI: 18%), 4% (95% CI: 36%), and 4% (95% CI: 27%), respectively. Mortality was 3% (95% CI: 24%). Comparison of outcomes between simple coiling and SAC revealed no significant difference, except for a higher likelihood of recanalization in the coiling group (Odds ratio, 3.51 [95% CI, 1.319.45]). Conclusions: Our meta-analysis demonstrates that EVT for RVSIA is a feasible, effective, and safe approach that is associated with favorable clinical outcomes in both the short and long term.
Braided Stents Y-Stent-Assisted Coiling with Low-Profile Bifurcation Aneurysms Treated by Initial and Long-Term Outcomes of Complex

BACKGROUND AND PURPOSE: Coiling complex intracranial bifurcation aneurysms often necessitates the implantation of double stents in various conﬁgurations, such as Y-stent placement. Low-proﬁle braided stents have been introduced recently to facilitate the endovascular treatment of wide-neck aneurysms. We aimed to investigate the feasibility, safety, efﬁcacy, and durability of Y-stent-assisted coiling with double low-proﬁle braided stents for the treatment of complex bifurcation aneurysms. MATERIALS AND METHODS: A retrospective review was performed to identify patients who were treated using Y-stent-assisted coiling with low-proﬁle braided stents. Technical success was assessed, as were initial and follow-up clinical and angiographic outcomes. Peripro-cedural and delayed complications were reviewed. Preprocedural and follow-up clinical statuses were assessed using the modiﬁed Rankin Scale. RESULTS: Forty patients with 40 intracranial aneurysms were included in the study. Y-stent placement was successfully performed in all cases. Immediate postprocedural digital subtraction angiography images revealed total aneurysm occlusion in 72.5% of cases. The mean angiographic follow-up time was 24.8 months. The last follow-up angiograms showed complete occlusion in 85% of patients. During follow-up, only 1 patient showed an increase in the ﬁlling status of the aneurysm and that patient did not require retreatment. There was no mortality in this study. The overall procedure-related complication rate, including asymptomatic complications, was 17.5%. A permanent morbidity developed in 1 patient (2.5%). CONCLUSIONS: The long-term angiographic and clinical outcomes of this retrospective study demonstrate that Y-stent-assisted

Deep Convolutional Neural Network Techniques On Denoising The Wireless Channel Corrupted Images

: Denoising the pictures faces numerous significant difficulties prior to being sent through the correspondence channel, the picture is compacted and sent as a bitstream. Various types of commotions debase this bitstream as it voyages through the correspondence channel. Thus, the beneficiary gets a boisterous (defiled) picture, which has a more terrible picture quality. Different picture denoising methods are used to defeat this issue. For quite a long time, picture denoising has been a captivating subject of examination. Many methodologies and ideas for picture denoising have been introduced over time. Most of these calculations accepted that the image commotions were Gaussian, rash and spot clamor are convoluted wellsprings of clamor in imaging.
A 0.20 mm² 3 nW signal acquisition IC for miniature sensor nodes in 65 nm CMOS

— Miniature mm 3 -sized sensor nodes have a very tight power budget, in particular, when a long operational lifetime is required, which is the case, e.g., for implantable devices or unobtrusive IoT nodes. This paper presents a fully integrated signal acquisition IC for these emerging applications. It integrates an ampliﬁer with 32 dB gain and 370 Hz bandwidth that includes positive feedback to enhance input impedance and dc offset compensation. The IC includes also a 10 bit 1 kS/s SAR ADC as well as a clock generator and voltage and current biasing circuits. The overall system achieves an input noise of 27 µ V rms , consumes 3 nW from a 0.6 V supply, occupies 0.20 mm 2 in 65 nm CMOS, and has a single-wire data interface. The ampliﬁer achieves an noise-efﬁciency factor (NEF) of 2.1 and the ADC has a ﬁgure-of-merit (FoM) of 1.5 fJ/conversion-step. Measurements conﬁrm reliable operation for supplies from 0.50 to 0.70 V and temperatures in the range of 0–85 ◦ C. As an application example, an ECG recording is successfully performed with the system while a 0 . 69 mm 2 photodiode array provides its power supply in indoor lighting conditions.
An Approach to Sentimental Analysis of Drug Reviews using AI

- In past years, large amount of data in various forms is available for use in medical domain to analyse various health conditions. The reviews in the medical industry are based on price, side-effects, user experience and proper dosage. The drug reviews are much more complicated as they contain medical terminologies like chemical used in drugs, medical health conditions etc. To overcome these issues this paper proposes a recommendation system based on a hybrid RNN stacked with bi-directional LSTM model and a gradient boosting framework, LightGBM classifier, which takes health condition as the input and recommends the best drugs based on the analysis of the reviews with 83% accuracy.
