Intermittent catheterization in the management of post spinal cord injury (SCI) neurogenic bladder using new hydrophilic, with lubrication in close circuit devices – our own preliminary results

This article is a review of the related approaches in the field – including the newest ones associated with a specific retrospective study on in-patients from our Clinic Division (preliminary results). Aim. Study design : To objectively assess whether there are significant differences regarding some specific key biological and psychometric parameters related to the use of hydrophilic catheters vs. non-hydrophilic ones. Materials and Methods: We have evaluated the outcomes of long term IC using by comparatively using the afore-mentioned two different types of catheters, on two lots (totally 45 patients with mainly retention type of neurogenic bladder): 30 post SCI patients, using exclusively hydrophilic catheters and respectively, 10 same kinds of patients that used exclusively non-hydrophilic catheters. Additionally, there were 5 patients included in both lots as they have started IC with non-hydrophilic catheters and since 2008 they have switched on using hydrophilic ones. The methods used were primary data acquisition based on a unitary questionnaire and statistical analyses. Results and discussion : Mainly: the patients that used exclusively hydrophilic type of catheters (median: “None”) vs. those using exclusively non-hydrophilic type of catheters (median: “One every 4 months”) presented: a significantly lower number of inflammatory episodes at scrotal level (p-value: 0.0001 WT), a significantly lower number of post/intra/inter catheterization bleeding episodes (p-value: 0.0001 WT), a very slightly lower number of UTI activations and expressed a significant higher satisfaction level (p-value <0.0001 WT). However, speculating a conceptual relation with the lower number of inflammatory episodes at scrotal level, it is to be thought that bigger lots of patients could provide, in this respect, significant results too. This study is to be continued, in order to further validate these preliminary, quite promising results, on bigger lots through the complex/ rigorous assessment methodology already used.

Transdimensional Sampling Algorithms for Bayesian Variable Selection in Classification Problems With Many More Variables Than Observations

Model search in probit regression is often conducted by simultaneously exploring the model and parameter space, using a reversible jump MCMC sampler. Standard samplers often have low model acceptance probabilities when there are many more regressors than observations. Implementing recent suggestions in the literature leads to much higher acceptance rates. However, high acceptance rates are often associated with poor mixing of chains. Thus, we design a more general model proposal that allows us to propose models “further” from our current model. This proposal can be tuned to achieve a suitable acceptance rate for good mixing. The effectiveness of this proposal is linked to the form of the marginalization scheme when updating the model and we propose a new efficient implementation of the automatic generic transdimensional algorithm of Green (2003). We also implement other previously proposed samplers and compare the efficiency of all methods on some gene expression datasets. Finally, the results of these applications lead us to propose guidelines for choosing between samplers. Relevant code and datasets are posted as an online supplement.
Checkpointing and Migration of parallel processes based on Message Passing Interface

This paper presents a Checkpoint-based Rollback Recovery and Migration System for Message Passing Interface, ChaRM4MPI, for Linux Clusters. Some important fault tolerant mechanisms are designed and implemented in this system, which include coordinated checkpointing protocol, synchronized rollback recovery, process migration, and so on. Owing to ChaRM4MPI, the node transient faults can be recovered automatically, and the permanent fault can also be recovered through checkpoint mirroring and process migration techniques. Moreover, users can migrate MPI processes from one node to another manually for load balance or system maintenance. ChaRM4MPI is a user-transparent implementation and introduces a little running time overhead.
Reliability of gait performance tests in men and women with hemiparesis after stroke.

OBJECTIVE To assess the reliability of 6 gait performance tests in individuals with chronic mild to moderate post-stroke hemiparesis. DESIGN An intra-rater (between occasions) test-retest reliability study. SUBJECTS Fifty men and women (mean age 58+/-6.4 years) 6-46 months post-stroke. METHODS The Timed "Up & Go" test, the Comfortable and the Fast Gait Speed tests, the Stair Climbing ascend and descend tests and the 6-Minute Walk test were assessed 7 days apart. Reliability was evaluated with the intraclass correlation coefficient (ICC(2,1)), the Bland & Altman analysis, the standard error of measurement (SEM and SEM%) and the smallest real difference (SRD and SRD%). RESULTS Test-retest agreements were high (ICC(2,1) 0.94-0.99) with no discernible systematic differences between the tests. The standard error of measurement (SEM%), representing the smallest change that indicates a real (clinical) improvement for a group of individuals, was small (< 9%). The smallest real difference (SRD%), representing the smallest change that indicates a real (clinical) improvement for a single individual, was also small (13-23%). CONCLUSION These commonly used gait performance tests are highly reliable and can be recommended to evaluate improvements in various aspects of gait performance in individuals with chronic mild to moderate hemiparesis after stroke.
Facial mimicry in its social setting

In interpersonal encounters, individuals often exhibit changes in their own facial expressions in response to emotional expressions of another person. Such changes are often called facial mimicry. While this tendency first appeared to be an automatic tendency of the perceiver to show the same emotional expression as the sender, evidence is now accumulating that situation, person, and relationship jointly determine whether and for which emotions such congruent facial behavior is shown. We review the evidence regarding the moderating influence of such factors on facial mimicry with a focus on understanding the meaning of facial responses to emotional expressions in a particular constellation. From this, we derive recommendations for a research agenda with a stronger focus on the most common forms of encounters, actual interactions with known others, and on assessing potential mediators of facial mimicry. We conclude that facial mimicry is modulated by many factors: attention deployment and sensitivity, detection of valence, emotional feelings, and social motivations. We posit that these are the more proximal causes of changes in facial mimicry due to changes in its social setting.
A new reuse partitioning scheme for distributed antenna cellular systems

In this paper, we propose a reuse partitioning (RP) scheme for the distributed antenna cellular system (DACS), which can improve the system capacity significantly by spatial division multi-access (SDMA). Simulation shows that the capacity of proposed RP scheme is higher than the traditional RP scheme. Furthermore, in the case of moderate load, the capacity of the former scheme can be increased by 70% than the traditional one
Reversibility of β-Cell-Specific Transcript Factors Expression by Long-Term Caloric Restriction in db/db Mouse

Type 2 diabetes (T2D) is characterized by β-cell dedifferentiation, but underlying mechanisms remain unclear. The purpose of the current study was to explore the mechanisms of β-cell dedifferentiation with and without long-term control of calorie intake. We used a diabetes mouse model (db/db) to analyze the changes in the expression levels of β-cell-specific transcription factors (TFs) and functional factors with long-term caloric restriction (CR). Our results showed that chronic euglycemia was maintained in the db/db mice with long-term CR intervention, and β-cell dedifferentiation was significantly reduced. The expression of Glut2, Pdx1, and Nkx6.1 was reversed, while MafA expression was significantly increased with long-term CR. GLP-1 pathway was reactivated with long-term CR. Our work showed that the course of β-cell dedifferentiation can intervene by long-term control of calorie intake. Key β-cell-specific TFs and functional factors play important roles in maintaining β-cell differentiation. Targeting these factors could optimize T2D therapies.
Process Mining: Process Management with Data Mining

In this paper we propose new methods for ordering the Web pages returned from search engines. Given a few search keywords, nowadays most search engines could retrieve more than a few thousand Web pages. The problem is how to order the retrieved Web pages and then to present the most relevant Web pages first. We propose new factors to allow relevant Web pages to be ranked higher. The factors include keyword popularity, keyword to Web page popularity, and Web page popularity. The keyword to Web page popularity records which Web pages have been selected corresponding to the search keywords. The Web page popularity determines how often the Web pages have been selected and also how many popular keywords are contained in the pages. Using these popularity factors, our system is able to rank more popular pages higher, which will help most search engine users find the more popular and plausibly the more relevant pages.
Speech emotion recognition using combination of features

In this paper, we study how speech features' numbers and statistical values impact recognition accuracy of emotions present in speech. With Gaussian Mixture Model (GMM), we identify two effective features, namely Mel Frequency Cepstrum Coefficients (MFCCs) and Auto Correlation Function Coefficients (ACFC) extracted directly from speech signal. Using GMM supervector formed by values of MFCCs, delta MFCCs and ACFC, we conduct experiments with Berlin emotional database considering six previously proposed emotions: anger, disgust, fear, happy, neutral and sad. Our method achieve emotion recognition rate of 74.45%, significantly better than 59.00% achieved previously. To prove the broad applicability of our method, we also conduct experiments considering a different set of emotions: anger, boredom, fear, happy, neutral and sad. Our emotion recognition rate of 75.00% is again better than71.00% of the method of hidden Markov model with MFCC, delta MFCC, cepstral coefficient and speech energy.
Motivic Brown–Peterson invariants of the rationals

Let BPhni, 0 n1 , denote the family of motivic truncated Brown‐Peterson spectra over Q. We employ a “local-to-global” philosophy in order to compute the bigraded homotopy groups of BPhni. Along the way, we produce a computation of the homotopy groups of BPhni over Q2 , prove a motivic Hasse principle for the spectra BPhni, and reprove several classical and recent theorems about the K ‐theory of particular fields in a streamlined fashion. We also compute the bigraded homotopy groups of the 2‐complete algebraic cobordism spectrum MGL over Q. 55T15; 19D50, 19E15
Chemometrics in analytical chemistry – an overview of applications from 2014 to 2018

A compilation of papers published between 2014 and 2018 was evaluated. Many papers related to multivariate calibration and classification have been reported, as well as, design of experiments applications and artificial intelligence methods. Some applications were highlighted, as medical and pharmaceutical, food analysis, fuels, biological and forensic for the chemometric techniques on this review. Most studies are related to developing methods for practical solutions in industry or routine analysis. A promising scenario is shown considering the number of published papers: a total of 832 for this period using the keywords, multivariate classification, multivariate calibration, analysis, chemometrics, prediction, analytical chemistry, artificial neural networks (ANN), design of experiments (DoE) and factorial design. An useful overview for Analytical Chemistry researchers´ combined with Chemometrics is presented in this review.
Thread-Local Scope Caching for Real-time Java

There is increasing convergence between the fields of parallel andembedded computing. The demand for more functionality in embeddeddevices means that complex multicore architectures will be used. Inorder to promote scalability and obtain predictability, on-chipprocessor-local private memory subsystems will be used. Whilst atthe hardware level this is technical feasible, the more pressingproblem is how such memory is presented to the programmer and howits local access is policed.In this paper we illustrate how Java augmented by the Real-timeSpecification for Java can be used to present the abstraction of athread-local scoped memory area. We show how to enforce access to thememory area to a single real-time thread. We implement the model onthe JOP multiprocessor system and report on our experiences.
Wage Inequality and Returns to Education in Turkey: A Quantile Regression Analysis

This paper investigates the male wage inequality and its evolution over the 1994-2002 period in Turkey by estimating Mincerian wage equations using OLS and quantile regression techniques. Male wage inequality is high in Turkey. While it declined at the lower end of the wage distribution it increased at the top end of wage distribution. Education contributed to higher wage inequality through both within and between dimensions. The within-groups inequality increased and between-groups inequality decreased over the study period. The latter factor may have dominated the former contributing to the observed decline in the male wage inequality over the 1994-2002. Further results are provided for the wage effects of experience, public sector employment, geographic location, firm size, industry of employment and their contribution to wage inequality. Recent increases in FDI inflows, openness to trade and global technological developments are discussed as contributing factors to the recent rising within-groups wage inequality.
Semi-automatic Annotations in Unknown Environments

Unknown environments pose a particular challenge for augmented reality applications because the 3D models required for tracking, rendering and interaction are not available ahead of time. Consequently, authoring of AR content must take place on-line. This work describes a set of techniques to simplify the online authoring of annotations in unknown environments using a simultaneous localisation and mapping (SLAM) system. The point-based SLAM system is extended to specifically track and estimate high-level features indicated by the user. The automatic estimation of these complex landmarks by the system relieves the user from the burden of manually specifying the full 3D pose of annotations while improving accuracy. These properties are especially interesting for remote collaboration applications where either user interfaces on handhelds or camera control by the remote expert are limited.
Global cities, global justice?

ABSTRACT The global city is a contested site of economic innovation and cultural production, as well as profound inequalities of wealth and life chances. These cities, and large cities that aspire to ‘global’ status, are often the point of entry for new immigrants. Yet for political theorists (and indeed many scholars of global institutions), these critical sites of global influence and inequality have not been a significant focus of attention. This is curious. Theorists have wrestled with the nature and demands of global justice, but have for the most part supposed that the debate is between statist and cosmopolitan formulations. Questions of redistribution, immigration, humanitarian obligations, coercion at borders, and territorial rights have correspondingly been cast as either the domain of sovereign territorial states, or of the nascent web of supranational institutions that might bind those states and peoples, morally and legally. Examining some of these issues and arguments through the lens of the global city casts them in a new and informative light, and buttresses an associative turn in thinking about global justice.
The Influence of William James on the Spirituality of Alcoholics’ Anonymous

This article challenges Bevacqua and Hoffman’s (2010) seminal article in this journal on the degree to which Alcoholics Anonymous (AA) falls short in its attempt to download the complete spirituality of William James into the AA canon. Results of the analysis of this question reveal that AA has fully incorporated the depth of The Varieties of Religious Experience (1902/1985). When application of James’s pragmatic method is applied to AA, the organization emerges as complete, with the abundant fruit of almost 2 million members worldwide. AA practices are not exclusivist, and do not offer a “one size fits all” restrictive paradigm. Rather, inspired by James, AA consistently gives explicit permission to members to find a path of their own construction that develops into an inclusive paradigm that has a lifelong trajectory.
FDI and Wages: Evidence from Firm-Level and Linked Employer-Employee Data in Hungary, 1986-2008

We estimate the wage effects of foreign direct investment (FDI) with universal firm-level and linked employer-employee panel data containing 4,926 foreign acquisitions in Hungary. Matching on pre-acquisition data and controlling for fixed effects for firms and detailed worker groups, we find 12-28 percent effects on average wages. The wage effect mostly reverses for 983 foreign acquisitions later divested to domestic owners. We find positive effects for all worker types, occupations, and wage quantiles. The evidence implies little role for either measurement problems or residual selection, but suggests a strong cross-firm association of FDI wage premia with similar differentials in productivity.
A Robust Design for MISO Physical-Layer Multicasting Over Line-of-Sight Channels

This letter studies a robust design problem for far-field line-of-sight (LOS) propagation channels where phase errors are present. Compared with the commonly used additive error model, the phase error model is more suitable for capturing the uncertainty in an LOS propagation channel, as the dominant source of uncertainty lies in the phase. We consider a multiple-input single-output multicast scenario, in which our goal is to design a beamformer that minimizes the transmit power while satisfying probabilistic signal-to-noise ratio constraints. In particular, the probabilistic constraints give rise to a new computational challenge, as they involve random trigonometric forms. In this study, we propose to first approximate the random trigonometric form by its second-order Taylor expansion and then tackle the resulting random quadratic form using a Bernstein-type inequality. It follows that an approximately optimal beamformer can be obtained using the standard semidefinite relaxation technique. Such a design approach is applicable to both independent and correlated phase errors. In the simulations, we first show that if a nonrobust design (i.e., one that does not take phase errors into account) is used; then, the whole system may collapse. We then show that our proposed method is less conservative than the existing robust design based on Gaussian approximation and thus requires a lower power budget.
WNK4 is an essential effector of anterior formation in FGF signaling

With no lysine (K) (WNK) kinase family is conserved among many species and regulates SPAK/OSR1 and ion cotransporters. WNK is also involved in developmental and cellular processes, but the molecular mechanisms underlying its regulation in these processes remain unknown. In this study, we found that WNK4 is involved in fibroblast growth factor (FGF) signaling during Xenopus development. In Xenopus embryos, depletion of WNK4 by antisense morpholino oligonucleotides (MOs) results in a severe defect in anterior development and impaired expression of endogenous anterior markers. Defects in head formation or expression of anterior marker genes caused by suppression of endogenous WNK4 expression could be rescued by expression of wild‐type WNK4, but not mutant WNK4 lacking its kinase activity. It is notable that morphants of Xenopus WNK4 inhibited the expression of anterior marker genes and the target genes induced by FGF signaling. Moreover, knockdown of Wnk4 significantly reduced the phosphorylation level of Osr1 induced by FGF. These results provide the first evidence that FGF signaling regulates WNK4 function required for anterior formation in Xenopus development.
3D simulations of supernova remnants evolution including non-linear particle acceleration

If a sizeable fraction of the energy of supernova remnant shocks is channeled into energetic particles (commonly identified with Galactic cosmic rays), then the morphological evolution of the remnants must be distinctly modified. Evidence of such modifications has been recently obtained with the Chandra and XMM-Newton X-ray satellites. To investigate these effects, we coupled a semi-analytical kinetic model of shock acceleration with a 3D hydrodynamic code (by means of an effective adiabatic index). This enables us to study the time-dependent compression of the region between the forward and reverse shocks due to the back reaction of accelerated particles, concomitantly with the development of the Rayleigh-Taylor hydrodynamic instability at the contact discontinuity. Density profiles depend critically on the injection level eta of particles: for eta up to about 10^-4 modifications are weak and progressive, for eta of the order of 10^-3 modifications are strong and immediate. Nevertheless, the extension of the Rayleigh-Taylor unstable region does not depend on the injection rate. A first comparison of our simulations with observations of Tycho's remnant strengthens the case for efficient acceleration of protons at the forward shock.
Architecture design for management as a service cloud

This paper presents a novel Management-as-a-Service (MaaS) architecture which is based on cloud computing architecture and provides more scalable network management capabilities to network managers. Ontology based semantic information model which supports communications between management services described by heterogeneous information, and functional model which schedules the deployment of each management service are designed to support the cloud network management architecture by providing appropriate management information description and service deployment method. We realize a prototype of cloud network management architecture based on the MaaS model, evaluate the performance of cloud network management services and validate the functional model used in the MaaS cloud. Experiment results show that our functional model provides optimal deployment of each cloud service and the elasticity of cloud management services improve both the management efficiencies and the utilization of management resources.
