Generalized Pair Weights of Linear Codes and Linear Isomorphisms Preserving Pair Weights

In this paper, we introduce the notion of generalized pair weights of an <inline-formula> <tex-math notation="LaTeX">$[n, k]$ </tex-math></inline-formula>-linear code over the finite field <inline-formula> <tex-math notation="LaTeX">$\mathbb {F}_{q}$ </tex-math></inline-formula> and the notion of pair <inline-formula> <tex-math notation="LaTeX">$r$ </tex-math></inline-formula>-equiweight codes, where <inline-formula> <tex-math notation="LaTeX">$1\le r\le k-1$ </tex-math></inline-formula>. Some basic properties of generalized pair weights of linear codes over finite fields are derived. We obtain a necessary and sufficient condition for an <inline-formula> <tex-math notation="LaTeX">$[n,k]$ </tex-math></inline-formula>-linear code to be a pair equiweight code, and we characterize pair <inline-formula> <tex-math notation="LaTeX">$r$ </tex-math></inline-formula>-equiweight codes for any <inline-formula> <tex-math notation="LaTeX">$1\le r\le k-1$ </tex-math></inline-formula>. A necessary and sufficient condition for a linear isomorphism to preserve pair weights between two linear codes is obtained. At the end of this paper, an application of generalized pair weights of linear codes to symbol-pair read wire-tap channels of type II is introduced.
A Framework for BPM Software Selection in Relation to Digital Transformation Drivers

: Business process management (BPM) is nowadays almost a traditional paradigm of assuring operational excellence. Within emerging approaches for boosting organizational readiness and maturity to cope with digital challenges, BPM transforms as well. In order to investigate the role of BPM and BPM software (BPMS) in relation to these approaches we explore drivers of digital transformation (DT). Based on the mapping of BPMS dimensions and drivers of DT, we propose a framework for self-assessment which allows evaluation of the significance of BPMS dimension in relation to DT. The framework was tested on multiple case-studies to analyse what their BPMS priorities are and how these priorities influence their digital transformation. AHP analysis was performed by prioritizing BPM's dimensions mapped with DT drivers and it served as a basis for assessing the level of digital maturity of the observed companies. This article therefore deals with the following: (1) it briefly discusses BPM and DT as concepts, (2) it demonstrates how AHP can serve for selecting BPM software and (3) it shows that BPM dimensions can be linked to Digital Transformation.
MIXTURE OF IDENTICAL DISTRIBUTIONS OF EXPONENTIAL, GAMMA, LOGNORMAL, WEIBULL, GOMPERTZ APPROACH TO HETEROGENEOUS SURVIVAL DATA

In this paper, a parametric mixture heterogeneous survival data. Mixtures of Exponential Gamma, Lognormal the simulate models were discussed. The Expectation Maximization Algorithm (EM) is implemented to estimate the maximum likelihood estimators of the parameters of mixture models. Si by simulating data, each randomly sampled from a population of two component parametric mixture model of identical distributions and the simulations has been repeated 500, 1000, 5000 times with samples of size 100 observations for of the EM algorithm. The repetitions of the simulation give estimators closer and closer to the postulated models, as the number of repetitions increases with relatively small standard errors. performances are compared using goodness of fit tests and Akaike's information criterion(AIC). Results revealed that the proposed model fits the real data better than the pure classical survival models corresponding to each component.
Strain-enhanced high Q-factor GaN micro-electromechanical resonator

ABSTRACT We report on a highly sensitive gallium nitride (GaN) micro-electromechanical (MEMS) resonator with a record quality factor (Q) exceeding 105 at the high resonant frequency (f) of 911 kHz by the strain engineering for the GaN-on-Si structure. The f of the double-clamped GaN beam bridge is increased from 139 to 911 kHz when the tensile stress is increased to 640 MPa. Although it is usually regarded that the energy dissipation increases with increasing resonant frequency, an ultra-high Q-factor which is more than two orders of magnitude higher than those of the other reported GaN-based MEMS is obtained. The high Q-factor results from the large tensile stress which can be intentionally introduced and engineered in the GaN epitaxial layer by utilizing the lattice mismatch between GaN and Si, leading to the stored elastic energy and drastically decreasing the energy dissipation. The developed GaN MEMS is further demonstrated as a highly sensitive mass sensor with a resolution of 10−12 g/s through detecting the microdroplet evaporation process. This work provides an avenue to improve the f × Q product of the MEMS through an internally strained structure. GRAPHICAL ABSTRACT
Damage tolerance of six dental zirconias with different translucencies

Abstract Purpose High-translucent dental zirconia has been introduced as a suitable material for anterior monolithic restorations. The material composition differs from traditional 3Y-TZP both with regard to yttria content and grain size. Little is known regarding how these alterations affect other properties than translucency and flexural strength. The aim of this study was to evaluate the crack propagation resistance and hardness of dental zirconias with different yttria content and different manufacturing methods. Materials and methods Measurement of hardness (HV2/5) and crack propagation from the indents (damage tolerance) was performed using a hardness tester(Vicker) on a flat polished surface of five crowns from six different commercial dental zirconias; one hard-machined 3Y-TZP, three soft-machined 3-5% yttria-stabilized zirconias and two soft-machined zirconias with ≥5% yttria content. Results Damage control varied greatly among dental zirconias with different compositions and fabrication methods. The hard-machined 3Y-TZP had better crack propagation resistance than soft-machined, 3-5% yttria-stabilized zirconias Conslusion The ultra-translucent zirconias with ≥5% yttria content had the lowest crack propagation resistance. Hardness is not a suitable indicator for damage tolerance.
Mesenchymal stromal cell-derived small extracellular vesicles restore lung architecture and improve exercise capacity in a model of neonatal hyperoxia-induced lung injury

ABSTRACT Early administration of mesenchymal stromal cell (MSC)-derived small extracellular vesicles (MEx) has shown considerable promise in experimental models of bronchopulmonary dysplasia (BPD). However, the ability of MEx to reverse the long-term pulmonary complications associated with established BPD remains unknown. In this study, MEx were isolated from media conditioned by human Wharton’s Jelly-derived MSC cultures. Newborn mice (FVB strain) were exposed to hyperoxia (HYRX (75% O2)) before returning to room air at postnatal day 14 (PN14). Following prolonged HYRX-exposure, animals received a single MEx dose at PN18 or serial MEx treatments at PN18-39 (“late” intervention). This group was compared to animals that received an early single MEx dose at PN4 (“early” intervention). Animals were harvested at PN28 or 60 for assessment of pulmonary parameters. We found that early and late MEx interventions effectively ameliorated core features of HYRX-induced neonatal lung injury, improving alveolar simplification, pulmonary fibrosis, vascular remodelling and blood vessel loss. Exercise capacity testing and assessment of pulmonary hypertension (PH) showed functional improvements following both early and late MEx interventions. In conclusion, delivery of MEx following prolonged HYRX-exposure improves core features of experimental BPD, restoring lung architecture, decreasing pulmonary fibrosis and vascular muscularization, ameliorating PH and improving exercise capacity. Taken together, delivery of MEx may not only be effective in the immediate neonatal period to prevent the development of BPD but may provide beneficial effects for the management and potentially the reversal of cardiorespiratory complications in infants and children with established BPD.
miR-23a-3p-abundant small extracellular vesicles released from Gelma/nanoclay hydrogel for cartilage regeneration

ABSTRACT Articular cartilage has limited self-regenerative capacity and the therapeutic methods for cartilage defects are still dissatisfactory in clinic. Recent studies showed that exosomes derived from mesenchymal stem cells promoted chondrogenesis by delivering bioactive substances to the recipient cells, indicating exosomes might be a novel method for repairing cartilage defect. Herein, we investigated the role and mechanism of human umbilical cord mesenchymal stem cells derived small extracellular vesicles (hUC-MSCs-sEVs) on cartilage regeneration. In vitro results showed that hUC-MSCs-sEVs promoted the migration, proliferation and differentiation of chondrocytes and human bone marrow mesenchymal stem cells (hBMSCs). MiRNA microarray showed that miR-23a-3p was the most highly expressed among the various miRNAs contained in hUC-MSCs-sEVs. Our data revealed that hUC-MSCs-sEVs promoted cartilage regeneration by transferring miR-23a-3p to suppress the level of PTEN and elevate expression of AKT. Moreover, we fabricated Gelatin methacrylate (Gelma)/nanoclay hydrogel (Gel-nano) for sustained release of sEVs, which was biocompatible and exhibited excellent mechanical property. In vivo results showed that hUC-MSCs-sEVs containing Gelma/nanoclay hydrogel (Gel-nano-sEVs) effectively promoted cartilage regeneration. These results indicated that Gel-nano-sEVs have a promising capacity to stimulate chondrogenesis and heal cartilage defects, and also provided valuable data for understanding the role and mechanism of hUC-MSCs-sEVs in cartilage regeneration.
Quantitative Assessment with Radiotracers of Sperm Transfer by Male Aedes Aegypti (Diptera: Culicidae)

A method was developed for quantitatively monitoring sperm transfer in male Aedes aegypti using radioactive tracers. Adenine-3H(G) was incorporated into sperm at sufficiently high levels to be readily detected in inseminated females by means of liquid scintillation spectrophotometry. The macromolecular distribution of the transferred radioactivity was determined by trichloroacetic acid precipitation and gross chemical fractionation. Forty-six percent of the radioactivity in females was found to be incorporated into DNA. Autoradiography demonstrated the localization of the transferred radioactivity in the spermathecae. This confirmed that radioactivity in the female was a result of sperm transfer and not external contamination; the levels of radioactivity were found to be directly proportional to sperm numbers. The behavior and survival of the male and the ability of the sperm to fertilize eggs were unaffected by the isotope at the dosages used.
Gamma-ray constraints on decaying Dark Matter

New bounds on decaying Dark Matter (DM) are derived from the γ-ray measurements of (i) the isotropic residual (extragalactic) background by Fermi and (ii) the Fornax galaxy cluster by H.E. S.S. We find that those from (i) are among the most stringent constraints currently available, for a large range of DM masses and a variety of decay modes, excluding half-lives up to ∼1026 to few 1027 seconds. In particular, they rule out the interpretation in terms of decaying DM of the e ± spectral features in PAMELA, Fermi andH.E. S.S. , unless very conservative choices are adopted. We also discuss futu re prospects for CTA bounds from Fornax which, contrary to the present H.E. S.S. constraints of (ii), may allow for an interesting improveme nt and may become better than those from the current or future extragalactic Fermi data.
Implementing WS-CDL Lars-˚Ake Fredlund

The WS-CDL deﬁnition, currently a W3C candidate recommendation, describes a language which is meant for characterising interactions between distinct web services. However, so far there are few tools that allow to check and execute speciﬁcations written in the new WS-CDL language. Apart from missing tool support, many basic language features are currently poorly understood. In contrast to traditional languages for describing Web Service interaction, the WS-CDL does not describe traditional two-party communications from the point-of-view of one of the participants. Rather, the WS-CDL language describe interaction scenarios involving multiple parties and from a viewpoint independent of its process participants. To allow us to experiment with the new language, and in general gain more insight in the design principles of the WS-CDL standard proposal, we have implemented a tool that allow us to syntax check, execute and de-bug WS-CDL descriptions, and which in the near future will allow model checking of WS-CDL descriptions.
Bimodal imaging at ICON using neutrons and X-rays

For experiments with low contrast between the relevant features it can be beneficial to add a second modality to reduce ambiguity. At Paul Scherrer Institut the two neutron imaging facilities NEUTRA (thermal neutrons) and ICON (cold neutrons) we have installed X-ray beamlines for on-site bimodal imaging with neutrons and X-rays. This allows us to leave the sample untouched in the sample environment throughout an experiment and to reduce the waiting times between acquisitions using each modality. The applications and energy ranges of the X-ray installations are different at the two facilities. At NEUTRA larger samples are intended (60-320kV) and at ICON small samples and simultaneous acquisition are intended (40-150kV). Here, we report the more recent installation at ICON. The X-ray beamline uses a cone beam source and is arranged across the neutron beamline. The beamline is designed to allow up to ten times magnification. This matches the voxel-size that can be achieved with the micro-setup for neutrons. The oblique arrangement of the X-ray beamline further makes real-time acquisition possible since both modalities have a free view of the sample at any time. Reconstruction of cone beam data requires more knowledge about the beam geometry and sample position. Therefore, the beamline is equipped with laser based distance sensors and a calibration procedure has been developed to increase the accuracy of the reconstruction. The purpose of using multimodal acquisition is to fuse the data in a way that enhances the output of the experiment. We demonstrate the current system performance and provide a basic analysis with experiment data. c © 2016 The Authors. Published by Elsevier B.V.

Let F be a general dynamical system defined on a complete locally compact metric spaceX. We give a slightly improved version of the Lyapunov characterization of asymptotic stability in one of our previous works and provide a short self-contained proof for the existence of arbitrarily small positively invariant neighborhoods of compact asymptotically stable sets in the present context. Based on these results, we prove that the uniform attractors ofF are connected and are stable with respect to perturbations under appropriate conditions. We are also interested in the dynamical properties of differential inclusion:x′(t) ∈ f (x(t)) on Rm. First, we show that if no solutions of the system blow up in finite future time, then its reachable mapping F is a general dynamical system. Then we discuss some asymptotic stability properties of the system. In particular, we prove that if there exists a nonempty compact connected subset M of Rm such thatM attracts a neighborhood of itself, then the system has a connected uniform attractor A. We also prove that A is stable with respect to both internal and external perturbations. More precisely, we prove that when λ > 0 is sufficiently small, the perturbed system: x′(t) ∈ conf (x(t)+λ B1)+λ B1 has a connected uniform attractor Aλ; moreover,δH(Aλ,A) → 0 asλ → 0, whereδH(· , ·) is the Hausdorff distance in Rm.  2002 Elsevier Science (USA).

Performance Evaluation of Amaltari Bufferzone Community Homestay of Kawasoti Municipality in Nawalpur, Nepal

This study analyzed performance evaluation of Amaltari Bufferzone Community Homestay (ABCH) of Kawasoti Municipality. This study followed post-positivist paradigm and survey methodology by applying evaluation indicators such as relevancy, efficiency, effectiveness, impact and sustainability. The research issueshave been theorized from social capital, ecotourism, asset based community developmentand sustainability approach on development.The survey result shows that relevancy got highest mean value 3.9922 with std. deviation 0.90575 which is followed by impact mean value 3.7871 with std. deviation 0.78242 and sustainability mean value 3.6325 with std. deviation 0.79901. It signifies that majority of respondents are relatively satisfied with relevancy, impact and sustainability related variables. More so, effectiveness secured least mean value 3.5145 with std. deviation 0.85903 that is followed by efficiency mean value 3.6052 with std. deviation 0.78690. The value its self is not disagreed views of the respondents but from evaluation perspectives it requires more attention. However, ABCH has performed effectively due to the strong social capital, conservation and mobilization fund, good networks of physical assets, as well as quality leaderships that has brought positive impacts in community and social level. Finally, this study has high implications in the sector of improving the lives of people residing around bufferzone through the tourism activities. The development priorities of the local government must encompass the positive impacts of integrated tourism for promoting the sustainable community development practices of the indigenous people living around the Amaltari Bufferzone of Chitwan National Park.
Concurrent functional targeting of anodal transcranial direct-current stimulation and motor task influences sensorimotor cortex activation

Functional targeting with anodal high-definition transcranial direct current stimulation (HDatDCS) of involved brain areas during performance of a motor task (online) may facilitate sensorimotor cortex neuroplasticity compared to performing the motor task after HD-atDCS (offline). The aim of this study was to employ functional near-infrared spectroscopy to compare the time course of motor task-related changes in sensorimotor cortex activation between online and offline HD-atDCS. We hypothesized that online HD-atDCS would have a greater effect on task-related sensorimotor cortex activation than offline HD-atDCS. In a within-subject sham controlled and randomized study design, 9 healthy participants underwent 3 HD-atDCS sessions (online, offline and sham) targeting the left sensorimotor cortex separated by 1 week. Functional near-infrared spectroscopy hemodynamic changes were measured from the left sensorimotor cortex during a simple finger opposition motor task before (Pre), immediately (T1) and 30 min after (T2) each session. The movement rates were not different between (online, offline, sham) or within (Pre, T1, T2) sessions. At T2, online HD-atDCS was associated with a significant increase and a large effect size in sensorimotor cortex activation (Hedges g = 1.01, p<0.001) when compared to sham; there was a nonsignificant trend to increase activation
Supplementary material to "Roles of Climate Variability on the Rapid Increase of Winter Haze Pollution in North China after 2010"

Abstract. North China experiences severe haze pollution in early winter, resulting in many premature deaths and considerable economic losses. The number of haze days in early winter in North China (HDNC) increased rapidly after 2010 but declined slowly before 2010, reflecting a trend reversal. Global warming and emissions were two fundamental drivers of the long-term increasing trend of haze, but no studies have focused on this trend reversal. The autumn SST in the Pacific and Atlantic, Eurasian snow cover and central Siberian soil moisture, which exhibited completely opposite trends before and after 2010, were proven to stimulate identical trends of meteorological conditions related to haze pollution in North China. Numerical experiments with a fixed emission level confirmed the physical relationships between the climate drivers and HDNC during both decreasing and increasing periods. These external drivers induced a larger decreasing trend of HDNC than the observations, and combined with the persistently increasing trend of anthropogenic emissions, resulted in a realistic slowly decreasing trend. However, after 2010, the increasing trends driven by these climate divers and human emissions jointly led to a rapid increase in HDNC.
AO INSU 2011 Section « Océan-Atmosphère » – MISTRALS Dossier scientifique SPEciMed – Structures of Planktonic Ecosystems in the North-western Mediterranean Foreword

The following document is the program that was produced in late 2009 and proposed for the first call of the ‘Chantier Méditerranée’ Project. This program received a favorable opinion of the selection committee but has, nevertheless, not been funded by the MISTRALS Project in 2010. The project was again included in the overall MISTRALS Project in response to the 2011 call for a duration which was extended until 2014. Following the recommandations of the first selection committee, SPEciMed keeps on the same objectives but wishes to gradually initiate the same type of approach in other Mediterranean sectors (Nice-Calvi transect in collaboration with the Université de Liège, transfer of competences towards the University of Bizerte then the University of Algiers, with which co-operations have been in progress with the LOPB for a few years).
Do They Want a Personal Relationship ?

Student priority ratings for personal developmental advising activities are compared with instructive prescriptive advfsing activities. Results indicate that students prefer prescriptive advising activities to developmental advising activities. However, review of the ratings for each advising activity reveals that students prefer a combination of these two advising roles, and it further suggests that there are limits to the degree of personal involvement desired. While stuoknt ratings do support the dual role of advising, i.e., offeering academic guidance within a n indiwidwzlizedlpersonal relationship, advisws who are attracted to the helopmental model of advising are cautioned to consider carefully how much personal counseling a student may desire. Suggestions for further research are also offered to determine which students prefer which type of advising relationship at what point in their academic development.
INTEGRATING BALANCED SCORECARD AND SIMULATION MODELLING TO IMPROVE EMERGENCY DEPARTMENT PERFORMANCE IN IRISH HOSPITALS

In the healthcare sector, there is a requirement for innovative solutions in managing the high levels of complexity and uncertainty within emergency departments (EDs). Simulation modeling is currently seen as a competent means of analyzing EDs, which allows changes effects to be understood and predicted more easily. The Balanced Scorecard (BSC), well-known performance management concept, has become a steering method in approaching new improvement cycles. This paper presents a methodology that integrates BSC and simulation modeling to increase ED efficiency and improve its performance in a University Hospital in North Dublin. BSC design began with understanding patient’s needs, ED activities, as well as training and development programs. Then a detailed simulation model was developed and integrated with the BSC to provide a comprehensive decision support system. This integrated model is used for evaluation and assessment of various decisions in emergency services and improving its performance.
