$ν$-net: Deep Learning for Generalized Biventricular Cardiac Mass and Function Parameters

Background: Cardiac MRI derived biventricular mass and function parameters, such as endsystolic volume (ESV), end-diastolic volume (EDV), ejection fraction (EF), stroke volume (SV), and ventricular mass (VM) are clinically well established. Image segmentation can be challenging and time-consuming, due to the complex anatomy of the human heart. Objectives: This study introduces ν-net (/nju:nεt/) – a deep learning approach allowing for fully-automated high quality segmentation of right (RV) and left ventricular (LV) endocardium and epicardium for extraction of cardiac function parameters. Methods: A set consisting of 253 manually segmented cases has been used to train a deep neural network. Subsequently, the network has been evaluated on 4 different multicenter data sets with a total of over 1000 cases. Results: For LV EF the intraclass correlation coefficient (ICC) is 98, 95, and 80 % (95 %), and for RV EF 96, and 87 % (80 %) on the respective data sets (human expert ICCs reported in parenthesis). The LV VM ICC is 95, and 94 % (84 %), and the RV VM ICC is 83, and 83 % (54 %). This study proposes a simple adjustment procedure, allowing for the adaptation to distinct segmentation philosophies. ν-net exhibits state of-the-art performance in terms of dice coefficient. Conclusions: Biventricular mass and function parameters can be determined reliably in high quality by applying a deep neural network for cardiac MRI segmentation, especially in the anatomically complex right ventricle. Adaption to individual segmentation styles by applying a simple adjustment procedure is viable, allowing for the processing of novel data without time-consuming additional training.

Deterministic and stochastic behaviour of non-Brownian spheres in sheared suspensions By GERMAN DRAZER

The dynamics of macroscopically homogeneous sheared suspensions of neutrally buoyant, non-Brownian spheres is investigated in the limit of vanishingly small Reynolds numbers using Stokesian dynamics. We show that the complex dynamics of sheared suspensions can be characterized as a chaotic motion in phase space and determine the dependence of the largest Lyapunov exponent on the volume fraction φ. We also offer evidence that the chaotic motion is responsible for the loss of memory in the evolution of the system and demonstrate this loss of correlation in phase space. The loss of memory at the microscopic level of individual particles is also shown in terms of the autocorrelation functions for the two transverse velocity components. Moreover, a negative correlation in the transverse particle velocities is seen to exist at the lower concentrations, an effect which we explain on the basis of the dynamics of two isolated spheres undergoing simple shear. In addition, we calculate the probability distribution function of the velocity fluctuations and observe, with increasing φ, a transition from exponential to Gaussian distributions. The simulations include a non-hydrodynamic repulsive interaction between the spheres which qualitatively models the effects of surface roughness and other irreversible effects, 2 such as residual Brownian displacements, that become particularly important whenever pairs of spheres are nearly touching. We investigate the effects of such a non-hydrodynamic interparticle force on the scaling of the particle tracer diffusion coefficient D for very dilute suspensions, and show that, when this force is very short-ranged, D becomes proportional to φ 2 as φ → 0. In contrast, when the range of the non-hydrodynamic interaction is increased, we observe a crossover in the dependence of D on φ, from φ 2 to φ as φ → 0. The phenomenon of shear-induced particle diffusion in suspensions at vanishingly small Reynolds number has been studied extensively since the work of Eckstein et al. (1977), where it was first suggested that a shear flow causes the particles to execute random migrations across the streamlines of the ambient flow producing an effect akin to dispersion. This hypothesis of a self-diffusive motion arising from purely viscous hydrodynamic interactions between particles has already received considerably experimental supportover, as pointed out by Breedveld et al. (2001b), the origin of this diffusive behaviour is clearly different from the more familiar Brownian diffusion in colloidal suspensions caused by thermal fluctuations, as well as turbulent diffusion driven by inertial effects, in …
A Practice Perspective on Technology-Mediated Network Relations: The Use of Internet-Based Self-Serve Technologies

E relationships with customers have been key in generating repeat business and economic advantage, especially in business-to-business settings. Such relationships are typically maintained through interpersonal interactions between customers and their providers. Lately, however, firms have been seeking to make their service operations more scalable by offering customers access to Internet-based, self-serve technology. This raises questions about the implications of inserting self-serve technology into embedded relationships. Recent research on the role of information technology (IT) within interfirm network relations suggests that relationships and the use of IT are complementary. However, most of this research focuses on the organizational level and fails to consider the instantiation of these interfirm relations by the actions and interactions of individual actors (e.g., customers and salespeople) representing their respective firms. In this paper, we explore the implications of using IT within interfirm relations through an analysis of customers’ and sales representatives’ (reps) work activities and interpersonal relationships. We apply a practice perspective that highlights how macrolevel phenomena such as interfirm relations are created and recreated through the microlevel actions taken by firm members. This analysis reveals that managing the complementarity between relationships and IT in practice is fraught with considerable tension. This study of WebGA, a bricks-and-clicks dotcom, highlights how the use of the self-serve technology made it more difficult for sales reps to build and maintain embedded relationships with their customers. The use of IT altered the nature and quality of information shared by the participants, undermined the ability of sales reps to provide consulting services to customers, reduced the frequency of their interaction, and prompted sales reps to expend social capital to promote customers’ technology adoption. These changes produced intended and unintended shifts in the network relations enacted by WebGA and its customers, and raised serious challenges to the viability of WebGA’s business model.
iRDM: A solution for workforce supply chain management in an outsourcing environment

Workforce is crucial to the success of service industry, especially for those software and consulting firms, where much of their revenue comes from the assignment of highly-skilled professionals. This is even more critical in the outsourcing environment, under which some of the professionals are outsourced from external vendors. Thus it is important to ensure hiring\assigning right people at the right time for the right project with the right cost. iRDM (intelligent Resource Deployment Manager) is an integrated solution developed by IBM Research division to support the full lifecycle management of highly-skilled professionals in the outsourcing environment. Based on the concept of "workforce supply chain", iRDM covers both the demand side and the supply side, and the matching between demand and supply. Besides the framework and software platform of iRDM, the demand and supply matching problem is mainly discussed. This solution has already been successfully deployed in an IBM consulting division.
Evaluating the Impact of Programming Language Features on the Performance of Parallel Applications on Cluster Architectures

We evaluate the impact of programming language features on the performance of parallel applications on modern parallel architectures, particularly for the demanding case of sparse integer codes. We compare a number of programming languages (Pthreads, OpenMP, MPI, UPC) on both shared and distributed-memory architectures. We find that language features can make parallel programs easier to write, but cannot hide the underlying communication costs for the target parallel architecture. Powerful compiler analysis and optimization can help reduce software overhead, but features such as fine-grain remote accesses are inherently expensive on clusters. To avoid large reductions in performance, language features must avoid degrading the performance of local
Modulation of molecular imprints in the antigen-experienced B cell repertoire by rituximab.

OBJECTIVE
Transient B cell depletion by rituximab has recently gained more importance in the treatment of rheumatic disorders. Nevertheless, little is known about the reemerging B cells. We analyzed dynamic changes in the repopulating B cells, particularly the postswitch B cells, and studied the mutational patterns of Ig genes in antigen-experienced B cells.


METHODS
Five patients with active rheumatoid arthritis (RA) were treated with rituximab. In 3 patients, B cell receptor (BCR) gene analysis was performed before treatment and during B cell recovery using genomic DNA. In 2 patients, B cell subsets were studied during the early recovery phase using single-cell technology. For comparison, immunophenotyping of B cell subsets was performed.


RESULTS
Early B cell recovery was marked by a relatively expanded population of highly mutated B cells, which were correlated with B cells with a plasmablast phenotype on comparative immunophenotyping. Analysis of the mutational pattern in these cells revealed increased RGYW/WRCY (where R = A/G, Y = C/T, and W = A/T) hotspot targeting (44% before rituximab versus 59% after) and elevated ratios of replacement to silent mutations within the complementarity-determining regions in Ig genes (1.87 before rituximab versus 2.67 after; P < or = 0.0025).


CONCLUSION
Our findings show that rituximab leads to qualitative changes in the imprints of highly mutated, antigen-experienced BCRs, representing the result of selection, whereas molecular processes such as Ig V rearrangements are not affected by this treatment.
Effect of drying methods on the physical properties and microstructures of mango (Philippine ‘Carabao’ var.) powder

0260-8774/$ see front matter 2012 Elsevier Ltd. A doi:10.1016/j.jfoodeng.2012.01.010 ⇑ Corresponding author. Address: 208 LJ Smith Ha USA. Tel.: +1 509 335 2140; fax: +1 509 335 2722. E-mail address: jtang@wsu.edu (J. Tang). Mango powders were obtained at water content below 0.05 kg water/kg dry solids using Refractance Window (RW) drying, freeze drying (FD), drum drying (DD), and spray drying (SD). The spray-dried powder was produced with the aid of maltodextrin (DE = 10). The chosen drying methods provided wide variations in residence time, from seconds (in SD) to over 30 h (in FD), and in product temperatures, from 20 C (in FD) to 105 C (in DD). The colors of RW-dried mango powder and reconstituted mango puree were comparable to the freeze-dried products, but were significantly different from drum-dried (darker), and spray-dried (lighter) counterparts. The bulk densities of drum and RW-dried mango powders were higher than freeze-dried and spray-dried powders. There were no significant differences (P 6 0.05) between RW and freeze-dried powders in terms of solubility and hygroscopicity. The glass transition temperature of RW-, freeze-, drumand spray-dried mango powders were not significantly different (P 6 0.05). The dried powders exhibited amorphous structures as evidenced by the X-ray diffractograms. The microstructure of RW-dried mango powder was smooth and flaky with uniform thickness. Particles of freeze-dried mango powder were more porous compared to the other three products. Drum-dried material exhibited irregular morphology with sharp edges, while spray-dried mango powder had a spherical shape. The study concludes that RW drying can produce mango powder with quality comparable to that obtained via freeze drying, and better than the drum and spray-dried mango powders. 2012 Elsevier Ltd.

Split and ST Bisimulation Semantics

In this paper the notion of action atomicity is relaxed by permitting actions to be observed in the middle of their evolution. Non atomic semantic equivalences, based on the notion of bisimulation, are studied over stable event structures. Splitn bisimulation equivalence (denoted n ) considers each event as composed of n phases. ST bisimulation equivalence (denoted ST ) is a slight refinement of 2 where each ending phase is unambiguously associated to a beginning phase. We prove that, by increasing n, we get finer and finer equivalences (i.e. n+1 n ) and, moreover, that n+1 coincides with ST over those event structures whose autoconcurrency is at most n. The main consequence of these results is that, for image finite event structures, ST is the intersection of all the n . This paper will appear in Information and Computation. 1.

Interventions for preventing falls in acute- and chronic-care hospitals: a systematic review and meta-analysis.

OBJECTIVES
To determine the characteristics and the effectiveness of hospital fall prevention programs.


DESIGN
Systematic literature search of multiple databases (Medline, Cinahl, Precinahl, Invert, the Cochrane Library) and of the reference list of each identified publication.


SETTING
Inclusion of prospective controlled-design studies reporting the effectiveness of fall prevention programs in hospitals.


PARTICIPANTS
Two reviewers.


MEASUREMENTS
The methodological qualities of the studies were assessed based on 10 criteria. For the meta-analysis, the relative risk of a fall per occupied bed day (RR(fall)) and the relative risk of being a faller (RR(faller)) were calculated.


RESULTS
Eight studies met the inclusion criteria, of which four studies tested multifactorial interventions. Although these studies took place in hospitals, most were conducted on long-stay (mean length of stay (LOS) >1.5 years) and rehabilitation units (mean LOS 36.9 days). For analysis of the number of falls, one unifactorial and two multifactorial studies showed a significant reduction of 30% to 49% in the intervention group, with the greatest effect obtained in the unifactorial study that assessed a pharmacological intervention. The pooled RR(fall) for the four multifactorial studies became nonsignificant after adjustment for clustering (RR(fall)=0.82, 95% confidence interval (CI)=0.65-1.03). No studies reported a significant reduction, either single or pooled, in the number of fallers in the intervention group (pooled RR(faller)-0.87, 95% CI=0.70-1.08).


CONCLUSION
This meta-analysis found no conclusive evidence that hospital fall prevention programs can reduce the number of falls or fallers, although more studies are needed to confirm the tendency observed in the analysis of individual studies that targeting a patient's most important risk factors for falls actively helps in reducing the number of falls. These interventions seem to be useful only on long-stay care units.
Prevalence and Effect of Cyberbullying on Children and Young People: A Scoping Review of Social Media Studies.

IMPORTANCE
Social media has had a profound effect on how children and adolescents interact. While there are many benefits to the use of social media, cyberbullying has emerged as a potential harm, raising questions regarding its influence on mental health.


OBJECTIVE
To review existing publications that examine the health-related effects of cyberbullying via social media among children and adolescents.


EVIDENCE REVIEW
We searched 11 electronic databases from January 1, 2000, through January 17, 2012 (updated June 24, 2014). Studies were screened by 2 independent reviewers and were included if they reported primary research, described or evaluated the use of a social media tool in the context of cyberbullying, and were conducted with children or adolescents. Data were extracted by 1 reviewer and verified by a second. All studies were assessed by 2 reviewers for methodological quality using the Mixed Methods Appraisal Tool. Results were not pooled owing to heterogeneity in study objectives and outcomes; a narrative analysis is presented.


FINDINGS
Thirty-six studies in 34 publications were included. Most were conducted in the United States (21 [58.3%]), sampled middle and high school populations (24 [66.7%]), and included adolescents who were 12 to 18 years of age (35 [97.2%]). The median reported prevalence of cyberbullying was 23.0% (interquartile range, 11.0%-42.6%). Five studies reported inconsistent and/or weak correlations between cyberbullying and anxiety. Ten studies found a statistically significant association between cyberbullying and report of depression. Five studies investigated self-harm or suicidality, with conflicting results. Results indicate that the most common reason for cyberbullying is relationship issues, with girls most often being the recipients. Responses to cyberbullying are most often passive, with a pervasive lack of awareness or confidence that anything can be done.


CONCLUSIONS AND RELEVANCE
There is a consistent relationship across studies between cyberbullying and depression among children and adolescents; however, the evidence of the effect of cyberbullying on other mental health conditions is inconsistent. This review provides important information that characterizes cyberbullying within the context of social media, including attributes of the recipients and perpetrators, reasons for and the nature of bullying behaviors, and how recipients react to and manage bullying behaviors. This information is critical to the development of effective prevention and management strategies.
Cultural dimensions and social behavior correlates : Individualism-Collectivism and Power Distance Titre

This study presents the macrosocial and macropsychological correlates of two cultural dimensions, Individualism-Collectivism and Hierarchy, based on a review of cross-cultural research. Correlations between the culturelevel value scores provided by Hofstede, Schwartz and Trompenaars and nation-level indices confirm their criterion validity. Thus power distance and collectivism are correlated with low social development (HDI index), income differences (Gini index), the socio-political corruption index, and the competitiveness index. The predominantly Protestant societies are more individualist and egalitarian, the Confucianist societies are more collectivist; and Islamic sociRésumé Cette étude présente les facteurs macro-sociaux et macro-psychologiques de deux dimensions culturelles, l’Individualisme-Collectivisme et la Hiérarchie ou Distance au Pouvoir, dimensions basées sur certaines révisions des recherches dans le domaine transculturel. Les corrélations entre les valeurs, au niveau culturel, fournies par Hofstede, Schwartz et Trompenaars, et des index socio-économiques confirment la validité de ces dimensions. La distance de pouvoir et le collectivisme sont associés au bas développement social (indice HDI), aux différences de revenus (indice Gini), à l’indice de corruption sociopolitique et de compétitivité.

Non-ST elevation myocardial infarction (NSTEMI) in three hospital settings in South Africa: does geography influence management and outcome? A retrospective cohort study

BACKGROUND
Guidelines advise early angiography in non-ST elevation myocardial infarction (NSTEMI) to ensure an optimal outcome. Resource limitations in secondary hospitals in the Western Cape dictate a local guideline to treat NSTEMIs medically with out-patient assessment for angiography, unless mandatory indications for early angiography occur.


METHODS
A retrospective cohort study assessed NSTEMIs at Tygerberg Hospital (TBH), Karl Bremer Hospital (KBH) and Worcester Hospital (WH) over one year. Two cohorts were analysed, secondary hospitals (KBH and WH; SH) and secondary service within a tertiary hospital (TBH). Where differences were found, sub-analysis compared WH and KBH.


RESULTS
TBH and SH were similar at baseline and in clinical presentation. Cases at TBH were more likely to receive in-patient angiography (94 vs 51%, p < 0.0001), and had a lower in-patient mortality rate (6 vs 23%, p = 0.0326). There was no difference between KBH and WH in sub-analysis.


CONCLUSION
This study confirmed that the management and mortality of NSTEMIs in the public health sector in the Western Cape, South Africa is not influenced by geography, but rather by the level of service available in the hospital of first presentation.
