A comparative study on perceptual evaluations of sports shoe exterior colors in Taiwan
Authors: Shieh Meng‐Dar , Yeh Yu‐En 
Published: January 2014

AbstractWe investigated consumer psychology, perception, and aesthetics in relation to sports shoe colors in Taiwan. Semantic differential rating (three emotional adjective pairs) and preference rating questionnaires were distributed among 512 university students to investigate whether their responses to various sports shoe colors differed. The results show that black is one of the most popular colors for sports shoes. The participants preferred designs that incorporated white as the secondary color and disliked those that featured green as the main and secondary colors. In addition, designs incorporating black or red as the main color with a bright color as the secondary color were considered modern. Black and white designs were perceived to be more suited to formal occasions. Furthermore, when the area of the main color exceeded that of the secondary color, the participants perceived a strong sense of simplicity, unless the colors were blue and green. The participants preferred two‐color over one‐color designs, and three‐color designs had a higher correlation with participant preferences. Women required more time than men to evaluate a sample. The men typically examined the samples from a frontal angle, whereas the women focused on the sides of the sample. The scoring scale was polarized (e.g., highest score for modern was −10 and 10 for retro), rendering the values of the Pearson correlation coefficient analysis comparatively low, resulting in weak correlations between variables. However, the relative differences of these values retained referential value regarding objective quantification. © 2014 Wiley Periodicals, Inc. Col Res Appl, 40, 178–193, 2015

AbstractDisplays such as mobile phones are viewed under surround conditions that vary from dark night to bright sunlight. The overall goal of this study is to test the appropriateness of CIECAM02 for mobile displays, and modify it according to any insufficiency found. Firstly, the testing of CIECAM02 is described using the visual data from 2‐inch display of three achromatic backgrounds (gray, black, and white), and three surround conditions (dark, dim, and average). Secondly, CIECAM02 was tested under four surround conditions (dark, dim, average, and bright), and three displays (2‐, 4‐, and 7‐inch), with only the gray background used, to focus more on the surround conditions. Those twelve experimental phases were used to refine CIECAM02, considering the surround factors. The surround parameters (c, F, and NC) were optimized, and Ncb was modified from the CIECAM02; the modified model is named MobileCAM‐v1. Colourfulness prediction by MobileCAM‐v1 has been improved, especially for a black background under average surround condition. A further refined version of CIECAM02, MobileCAM‐v2, was developed, for mobile displays viewed under different surround conditions. A set of equations based on surrounding conditions was first derived, to be able to accurately define surround parameters. The MobileCAM‐v2 model gave the largest improvement in brightness, followed by lightness, and with colourfulness the smallest. The improvement is significant for bright surround conditions, improving the performance of CIECAM02 in predicting the visual results. © 2014 Wiley Periodicals, Inc. Col Res Appl, 40, 114–124, 2015
An OAM function to improve the packet loss in MPLS‐TP domains for prioritized QoS‐aware services
Authors: Rodríguez‐Pérez Francisco‐Javier , González‐Sánchez José‐Luis , Carmona‐Murillo Javier , Cortés‐Polo David 
Published: January 2014

SummaryThe emergence of new kinds of applications and technologies (e.g., data‐intensive applications, server virtualization, and big data technology) has led to a higher utilization of network resources. These services imply increased bandwidth consumption and unexpected congestions, especially in backbones. In this article, a novel proposal is studied with the aim of improving the performance of prioritized forwarding equivalence classes in congested Multiprotocol Label Switching Transport Profile (MPLS‐TP) domains. The congestion impact on those QoS‐aware services that require high reliability and low delay is analyzed. A new policy has been implemented on MPLS‐TP, which is a technology that provides QoS by means of flow differentiation in the Internet backbones. The proposal is known as Gossip‐based local recovery policy and is offered as an operation, administration, and management function to allow local recovery of lost traffic for MPLS‐TP privileged forwarding equivalence classes. In order to fulfill the requirements for implementation on MPLS‐TP, a minimum set of extensions to resource reservation protocol traffic engineering has also been proposed to provide self‐management capable routes. Finally, we have carried out a performance improvement measurement by means of an analytical model and simulations. Copyright © 2014 John Wiley & Sons, Ltd.
Effects of fault‐zone architecture on earthquake magnitude and gas leakage related to CO2 injection in a multi‐layered sedimentary system
Authors: Rinaldi Antonio P. , Jeanne Pierre , Rutqvist Jonny , Cappa Frédéric , Guglielmi Yves 
Published: January 2014

AbstractThe presence of fluid within a fault zone can cause overpressure and trigger earthquakes. In this work, we study the influence of fault‐zone architecture on pore pressure distribution and on the resulting fault reactivation caused by CO2 injection. In particular, we investigate the effect of the variation and distribution of lithological and rock physical properties within a fault zone embedded in a multi‐layer sedimentary system. Through numerical analysis, we compare several models where the complexity of the fault‐zone architecture and different layers (such as caprock and injection reservoir) are incrementally included. Results show how the presence of hydraulic and mechanical heterogeneity along the fault influences the pressure diffusion, as well as the effective normal and shear stress evolution. Hydromechanical heterogeneities (i) strengthen the fault zone resulting in earthquakes of small magnitude, and (ii) impede fluid migration upward along the fault. We also study the effects of the caprock and aquifer thickness on the resulting induced seismicity and CO2 leakage, both in heterogeneous and homogeneous fault zones. Results show that a thin caprock or aquifer allows smaller events, but a much higher percentage of leakage through the caprock and into the upper aquifer. The amount of leakage reduces drastically in the case of a multi‐caprock, multi‐aquifer system.
The family roles of siblings of people diagnosed with a mental disorder: Heroes and lost children
Authors: Sanders Avihay , Szymanski Kate , Fiori Kate 
Published: January 2014

AbstractIn order to cope with the diagnosis of mental illness in a family member, siblings may be forced to adjust their roles in the family. Taking into account the crucial role that some siblings play in caregiving for the mentally ill especially when the parents are no longer available, it is imperative to develop awareness of their unique needs and address them. Thirty‐three adult siblings of people diagnosed with a mental disorder completed the Role Behaviour Inventory (RBI) and a general questionnaire including open‐ended questions regarding the roles they played in their families of origin. Findings from the inventory and general questionnaire suggest that the well siblings score higher on two roles, the Hero and Lost Child, and lower on the Mascot and Scapegoat roles relative to a comparison group (N = 33). Being a sibling caregiver emerged as a risk factor to assume certain dysfunctional roles in the family. Implications for future research and therapy are discussed.

AbstractThe present study identified psychological well‐being profiles in a sample of Australian university students (N = 207, Mean age = 30.16 years;SD = 11.90). Respondents completed two measures: Ryff's (1989)Psychological Well‐Being(PWB) scale and Lovibond and Lovibond's (2002)Depression, Anxiety and Stress Scales‐21(DASS‐21) assessing their levels ofPWBand depression. Latent profile analysis was applied to six indices of positive functioning derived fromPWBscale:self‐acceptance,purpose in life,environmental mastery, positive relations with others,personal growthandautonomy. An optimal 5‐profile solution, reflecting significant incremental shifts from very low to very highPWB, was interpreted. As predicted, profile membership distinguished participants on depression. Importantly, profiles indicating moderate to very highPWB, particularly with the presence of above average autonomy, reported significantly lower levels of depression. Our results suggest prevention of, and treatment efficacy for, mental health problems may be improved by incorporating strategies that address positive functioning attributes, particularly associated with a sense of autonomy.
RESIDENTIAL CARE FOR ABANDONED CHILDREN AND THEIR INTEGRATION INTO A FAMILY‐BASED SETTING IN UGANDA: LESSONS FOR POLICY AND PROGRAMMING

Published: January 2014

ABSTRACTThis article describes a model of care for abandoned and neglected infants in need of urgent physical, social, and medical support as implemented by the Child's i Foundation, an international, nongovernmental organization operating in Uganda. The model discounts the need for long‐term care of young children within institutions and challenges the basis for intercountry adoption. Underpinned by the essentials of care continuum provided under the Uganda National Alternative Care Framework (Ministry of Gender, Labour and Social Development, 2012), the model emphasizes the need to effect the reintegration of the separated child within the family of his or her birth, or locally organize foster care or adoption. Highlighting policy and programming lessons, the model showcases a holistic approach to the problem and puts emphasis on interventions that are protective, promotional, and transformational and the use of a community‐oriented approach. The model offers guidance to both government and nongovernment actors in addressing the problems of child neglect and abandonment through the implementation of the alternative care framework.
Modulation of pain threshold by virtual body ownership
Authors: Martini M. , Perez‐Marcos D. , Sanchez‐Vives M.V. 
Published: January 2014

AbstractBackgroundAppropriate sensorimotor correlations can result in the illusion of ownership of exogenous body parts. Nevertheless, whether and how the illusion of owning a new body part affects human perception, and in particular pain detection, is still poorly investigated. Recent findings have shown that seeing one's own body is analgesic, but it is not known whether this effect is transferable to newly embodied, but exogenous, body parts. In recent years, results from our laboratory have demonstrated that a virtual body can be felt as one's own, provided realistic multisensory correlations.MethodsThe current work aimed at investigating the impact of virtual body ownership on pain threshold. An immersive virtual environment allowed a first‐person perspective of a virtual body that replaced the own. Passive movement of the index finger congruent with the movement of the virtual index finger was used in the ‘synchronous’ condition to induce ownership of the virtual arm. The pain threshold was tested by thermal stimulation under four conditions: (1) synchronous movements of the real and virtual fingers; (2) asynchronous movements; (3) seeing a virtual object instead of an arm; and (4) not seeing any limb in real world.ResultsOur results show that, independently of attentional and stimulus adaptation processes, the ownership of a virtual arm per se can significantly increase the thermal pain threshold.ConclusionsThis finding may be relevant for the development and improvement of digital solutions for rehabilitation and pain treatment.
Power motion‐mode doppler signature: A useful tool for assessing middle cerebral artery stenosis

Published: January 2014

ABSTRACTPurposeTo identify power motion‐mode Doppler (PMD) patterns and assess their diagnostic value for the diagnosis of middle cerebral artery (MCA) stenosis.MethodsRetrospective analyses of PMD data were performed for the identification of specific patterns related to MCA stenosis. The interrater reliability and the validity of these patterns were studied, using magnetic resonance angiography and conventional transcranial Doppler sonography as gold standards.ResultsThree PMD patterns were identified: the so‐called black‐hole, the white‐hole, and the diastolic‐band patterns in 58 among 178 MCAs. The mean flow velocity was significantly higher in arterial segments with the black‐hole patterns and lower in segments with the diastolic‐band pattern compared with the segments with normal patterns. The interrater reliability was good for each pattern. The black‐hole pattern or its combination with the white‐hole pattern showed the highest validity.ConclusionDespite some limitations, the black‐hole PMD pattern or its combination with the white‐hole pattern appeared as a reliable and valid marker for the diagnosis of MCA stenosis. © 2014 Wiley Periodicals, Inc.

Published: January 2014

AbstractBackgroundCytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are increasingly used to treat peritoneal carcinomatosis from colorectal cancer. It is still relatively unknown which poor prognostic factors to avoid in order to optimize patient selection for CRS + HIPEC.MethodsBetween February 2003 and October 2011, 68 consecutive colorectal cancer patients who underwent CRS + HIPEC with a complete cytoreduction were identified from a prospective database. Survival analysis was performed using the Kaplan–Meier method, with log rank testing of differences between groups. Multivariate analysis was conducted using Cox proportional hazard regression.ResultsMedian follow‐up was 30.3 (range, 2–88) months amongst survivors. Patients with a peritoneal cancer index (PCI) of 10 or less showed improved survival over those with a PCI of 11 or higher (P = 0.03). No difference in survival was seen for the other potentially poor prognostic variables including lymph node status, synchronous peritoneal disease, peri‐operative systemic chemotherapy, and rectal cancer primary.ConclusionsA low PCI was associated with improved survival. Complete CRS + HIPEC appears to result in similar survival outcomes regardless of delivery of peri‐operative systemic chemotherapy. Rectal origin, lymph node status, and synchronous peritoneal disease should not be used as an absolute exclusion criteria for CRS + HIPEC based on current data. J. Surg.

BackgroundEpithelial‐to‐mesenchymal transition (EMT) is considered to play an important role in cancer invasion and metastasis.MethodsThe mRNA levels of an epithelial marker (E‐cadherin), mesenchymal marker (vimentin), and Zeb‐1 were measured in 11 gastric cancer cell lines. Functional analysis was performed using Zeb‐1 knockdown. EMT status of 116 gastric cancer patients was determined by calculating the vimentin/E‐cadherin mRNA expression ratio in cancerous tissue and the correlation between EMT status, clinicopathological factors, prognosis, and Zeb‐1 were analyzed.ResultsCell lines were classified as epithelial or mesenchymal. Zeb‐1 expression was significantly correlated with the mesenchymal phenotype. Treatment with Zeb‐1 siRNA also reduced the capacity to proliferate, migrate, and invade. Patients were classified as epithelial or mesenchymal by V/E ratio (vimentin/E‐cadherin ratio) and as Zeb‐1 low or high expression group. The mesenchymal group was significantly associated with diffuse type cancer and stage IV. On multivariate analysis, the EMT status (mesenchymal group) was an independent prognostic factor (P = 0.022). There was a significant correlation between the V/E ratio and Zeb‐1 expression (r = 0.73). Patients in Zeb‐1 high group had significantly poorer survival than those in low group (P = 0.0071).ConclusionsEMT is a critical prognostic factor for gastric cancer. Zeb‐1 might be a promising therapeutic target. J. Surg. Oncol 2014; 109:684–689. © 2014 Wiley Periodicals, Inc.
Filtrodynamics 2: Effects of Particle Size and Filter Type on Trans‐Filter Time‐Dependent Pressure Signals
Authors: Dufrechou Marie , Mignard Emmanuel , Drenski Michael F. , Reed Wayne F. 
Published: January 2014

AbstractFiltrodynamic behavior of trans‐filter time‐dependent pressure signals ΔP(t) is determined for membrane and frit filters using latex spheres of varying diameter D. Membrane data are best interpreted via a time‐dependent, accreting filtration bed, based on Darcy's law. A single parameter, permeability k, describes each membrane/particle pair. For small particles, k increases with increasing D, then becomes D‐independent for large ones. Predictable behavior for polydisperse mixtures of small spheres is obtained. The mechanism and behavior of filtration for non‐membrane metallic frits is dramatically different, and better described by a previous “characteristic loading” model. Use of frit and membrane filters in series allowed monitoring each filter's separate response to particle accumulation.
Quantification of sweat gland volume and innervation in neuropathy: Correlation with thermoregulatory sweat testing
Authors: Loavenbruck Adam , Wendelschaefer‐Crabbe Gwen , Sandroni Paola , Kennedy William R. 
Published: January 2014

ABSTRACTIntroduction: No study has correlated thermoregulatory sweat testing (TST) with histopathologic study of sweat glands (SGs) and SG nerve fibers (SGNFs). Methods: We studied 10 neuropathy patients in whom anhidrosis was found by TST and 10 matched controls. Skin biopsies were taken from both anhidrotic and sweating skin and immunohistochemical staining was done for nerves and basement membrane. For each biopsy, total tissue volume, total SG volume, and total SGNF length were measured. SGNF length per biopsy volume, SG volume per biopsy volume (SG%), and SGNF length per SG volume were calculated. Results: SGNF length per biopsy volume was reduced in anhidrotic site biopsies of patients compared with controls. SG% was decreased and SGNF length per SG volume increased in patients compared with controls. Conclusions: The results suggest a concomitant loss of SG volume and SGNF length in neuropathy, with greater loss of SGNFs in anhidrotic skin, possibly exceeding collateral reinnervation.

Ensemble MD simulations restrained via crystallographic data: Accurate structure leads to accurate dynamics
Authors: Xue Yi , Skrynnikov Nikolai R. 
Published: January 2014

AbstractCurrently, the best existing molecular dynamics (MD) force fields cannot accurately reproduce the global free‐energy minimum which realizes the experimental protein structure. As a result, long MD trajectories tend to drift away from the starting coordinates (e.g., crystallographic structures). To address this problem, we have devised a new simulation strategy aimed at protein crystals. An MD simulation of protein crystal is essentially an ensemble simulation involving multiple protein molecules in a crystal unit cell (or a block of unit cells). To ensure that average protein coordinates remain correct during the simulation, we introduced crystallography‐based restraints into the MD protocol. Because these restraints are aimed at the ensemble‐average structure, they have only minimal impact on conformational dynamics of the individual protein molecules. So long as the average structure remains reasonable, the proteins move in a native‐like fashion as dictated by the original force field. To validate this approach, we have used the data from solid‐state NMR spectroscopy, which is the orthogonal experimental technique uniquely sensitive to protein local dynamics. The new method has been tested on the well‐established model protein, ubiquitin. The ensemble‐restrained MD simulations produced lower crystallographic R factors than conventional simulations; they also led to more accurate predictions for crystallographic temperature factors, solid‐state chemical shifts, and backbone order parameters. The predictions for 15N
relaxation rates are at least as accurate as those obtained from conventional simulations. Taken together, these results suggest that the presented trajectories may be among the most realistic protein MD simulations ever reported. In this context, the ensemble restraints based on high‐resolution crystallographic data can be viewed as protein‐specific empirical corrections to the standard force fields.
Impact of sequence on the molecular assembly of short amyloid peptides
Authors: Wagoner Victoria A. , Cheon Mookyung , Chang Iksoo , Hall Carol K. 
Published: January 2014

ABSTRACTThe goal of this work is to understand how the sequence of a protein affects the likelihood that it will form an amyloid fibril and the kinetics along the fibrillization pathway. The focus is on very short fragments of amyloid proteins since these play a role in the fibrillization of the parent protein and can form fibrils themselves. Discontinuous molecular dynamics simulations using the PRIME20 force field were performed of the aggregation of 48‐peptide systems containing SNQNNF (PrP (170–175)), SSTSAA (RNaseA(15–20)), MVGGVV (Aβ(35–40)), GGVVIA (Aβ(37–42)), and MVGGVVIA (Aβ(35–42)). In our simulations SNQQNF, SSTTSAA, and MVGGVV form large numbers of fibrillar structures spontaneously (as in experiment). GGVVIA forms β‐sheets that do not stack into fibrils (unlike experiment). The combination sequence MVGGVVIA forms less fibrils than MVGGVV, hindered by the presence of the hydrophobic residues at the C‐terminal. Analysis of the simulation kinetics and energetics reveals why MVGGVV forms fibrils and GGVVIA does not, and why adding I and A to MVGGVVIA reduces fibrillization and enhances amorphous aggregation into oligomeric structures. The latter helps explain why Aβ(1–42) assembles into more complex oligomers than Aβ(1–40), a consequence of which is that it is more strongly associated with Alzheimer's disease.
