Abstract
Introduction
Developing cartilage constructs with injectability, appropriate matrix composition and persistent cartilaginous phenotype remains an enduring challenge in cartilage repair. Bone marrow derived mesenchymal stem cells (BMSCs) have chondrogenic potential. Current approaches to drive their chondrogenic differentiation require extensive cell manipulation ex vivo and using exogenous growth factors. However, preventing hypertrophic transition of BMSCs in vivo and maintaining persistent chondrogenesis remain bottlenecks in clinical application. This study aimed to develop completely biological, injectable constructs to generate cartilage by co-transplanting chondrocyte and BMSCs.

Methods
We fabricated fragmented chondrocyte macroaggregate (cell bricks) and mixed them with platelet rich plasma (PRP); BMSCs were mixed into the above constructs, allowed to clot and then subcutaneously injected into nude mice. Gross morphology observation, histological and immunohistochemical assay, immunofluorescence assay, biochemical analysis and gene expression analysis were used to compare the properties of BMSC-cell bricks-PRP complex with BMSC in PRP or BMSC/chondrocytes in PRP.

Results
The constructs of BMSCs-cell bricks-PRP that were subcutaneously injected resulted in persistent chondrogenesis with appropriate morphology, adequate central nutritional perfusion without central necrosis or ossification, and further augmented nasal dorsum without obvious contraction and deformation.

Conclusions
We concluded that cell bricks-enriched PRP clotting provides an autologous substance derived niche for chondrogenic differentiation of BMSCs in vivo, which suggests that such an injectable, completely biological system is a suitable stem cell carrier for micro-invasive cartilage repair.
Zero-forcing beamforming for physical layer security of energy harvesting wireless communications
Authors: Zhu Fengchao , Gao Feifei , Yao Minli 
Published: March 2015

Abstract
In this paper, we consider the physical layer security for simultaneous wireless information and power transfer (SWIPT) in a multiple-input single-output (MISO) system that is consisted of three nodes: one transmitter with multiple antennas, one information decoding (ID) receiver with single antenna, and one energy harvesting (EH) receiver with single antenna. We propose a new zero-forcing based strategy that contains both the information beamforming and the energy beamforming, pointing to different receivers. To prevent the energy receiver from possibly eavesdropping the information, our target is to maximize the secrecy-rate of the ID receiver while at the same time maintaining a minimum required energy for the EH receiver. For the case that artificial noise is not used, the original non-convex problem can be directly converted into convex subproblems, where the closed-form optimal solutions are derived. For the case that artificial noise is used, the initial non-convex problem can be decomposed into two quasi-convex subproblems where closed-form solutions are derived, and the global optimal solutions are obtained with the aid of one-dimensional search. Simulations results demonstrate the trade-off between the maximum secret information rate and the transferred energy, which is characterized by the boundary of secret rate-energy (R-E) region.

Abstract
Our recent studies demonstrated that habitual exercise plus dietary supplementation with milk fat globule membrane (MFGM) improved endurance capacity and muscle function by stimulating neuromuscular development in mice. The aim of this study was to investigate the efficacy of dietary MFGM supplementation plus habitual exercise on the physical performance of middle-aged Japanese adults in a pilot randomized, double-blind, placebo-controlled trial. Forty-four subjects (men, n = 22; women, n = 22) were randomly assigned into two groups: one received placebo tablets (placebo group, n = 22 [men, n = 11; women, n = 11]), while the other received MFGM tablets (MFGM group, n = 22 [men, n = 11; women, n = 11]). The subjects ingested either MFGM (1 g/day) or placebo (1 g/day of whole milk powder) tablets every day for the 10-week study period and engaged in an exercise training program twice per week. A physical function test was performed at baseline and at 5 and 10 weeks. A significant group-by-time interaction was found for the side step test, muscle cross-sectional area (CSA), and muscle fiber conduction velocity (MFCV). In the placebo group, there were no significant intragroup differences. In the MFGM group, side step score and muscle CSA were significantly greater at 10 weeks compared to the baseline, and MFCV was significantly higher than that in the placebo group at 10 weeks. The changes in percentage of the side step score, muscle CSA, and MFCV in the MFGM group were significantly higher than in the placebo group at 10 weeks. These results suggest that daily MFGM ingestion combined with regular exercise might enhance physical performance such as agility in middle-aged adults.

Abstract

Background
In the view of depleting resources and ever-increasing price of crude oil, there is an urge for the development of alternative sources to solve the issue of fuel in the coming years. Lignocellulosic biomass is considered to be the most potential alternative resources for fossil fuel. Bioconversion of cellulosic and hemicellulosic components into fermentable sugars is the key step in producing fuel ethanol from lignocellulose. The enzymatic hydrolysis of lignocellulosic biomass needs a highly balanced composition of cellulases and hemicellulases. Commercial enzymes are usually poor in accessory hemicellulolytic enzymes like α-L-arabinofuranosidase. The addition of such accessory enzymes in combination with cellulase or hemicellulase plays a vital role in improving the total yield of fuel ethanol by enhancing the saccharification yield.

Results
The newly isolated fungal strain Aspergillus niger ADH-11 produced a maximum of 22.14 U/g of α-L-arabinofuranosidase under solid-state fermentation using wheat bran as the substrate and modified Mandels-Weber medium at 30°C after 180 h of incubation. The optimization of various fermentation parameters was performed by response surface methodology employing Plackett-Burman design followed by Box-Behnken design. The yield of α-L-arabinofuranosidase was enhanced by 2.34-fold after executing statistical optimization of various fermentative parameters. Crude α-L-arabinofuranosidase was found to be highly stable for 3 h at its optimum temperature (55°C) and pH (4.0). The assessment of the crude enzyme extract in saccharification of alkali-treated maize stover revealed that the supplementation of crude α-L-arabinofuranosidase to commercial cellulase and crude xylanase mixture increased the saccharification yield up to 730 mg/g of maize stover.

Conclusions
The newly isolated A. niger ADH-11 was found to be a potential producer of α-L-arabinofuranosidase. The crude enzyme was active at low pH and high temperature which makes it suitable for various industrial applications such as enzymatic saccharification of lignocellulosic biomass. The supplementation of α-L-arabinofuranosidase enzyme to commercial cellulases and hemicellulases improves the bioconversion of lignocellulosic biomass to a greater extent.
Uncertainty in reservoir modeling
Authors: Pyrcz Michael J. , White Christopher D. 
Published: March 2015

Uncertainty is due to incomplete and imprecise knowledge as a result of limited sampling of the subsurface heterogeneities. Well data and seismic data have incomplete coverage and finite resolution. The interpretations are uncertain. Reservoirs are heterogeneous and difficult to predict away from wells. Ignoring uncertainty and locking in important model parameters and choices amounts to an assumption of perfect knowledge and is generally an unacceptable approach. Uncertainty must be explicitly modeled. Understanding the (1) sources of uncertainty, (2) methods to represent uncertainty, (3) the formalisms of uncertainty, and (4) uncertainty modeling methods and workflows were essential for the integration of all reservoir information sources and providing good models for decision making in the presence of uncertainty.

AbstractGlucose is an essential nutrient that directly regulates the expression of numerous genes in liver and adipose tissue. The carbohydrate response element–binding protein (ChREBP) links glucose as a signaling molecule to multiple glucose-dependent transcriptional regulatory pathways, particularly genes involved in glycolytic and lipogenic processes. In this study, we used chromatin immunoprecipitation followed by next-generation sequencing to identify specific ChREBP binding targets in liver and white adipose tissue. We found a large number of ChREBP binding sites, which are attributable to 5825 genes in the liver, 2418 genes in white adipose tissue, and 5919 genes in both tissues. The majority of these target genes were involved in known metabolic processes. Pathways in insulin signaling, the adherens junction, and cancers were among the top 5 pathways in both tissues. Motif analysis revealed a consensus sequence CAYGYGnnnnnCRCRTG that was commonly shared by ChREBP binding sites. Putative ChREBP binding sequences were enriched on promoters of genes involved in insulin signaling pathway, insulin resistance, and tumorigenesis.
Dynamic Equilibria in Fluid Queueing Networks
Authors: Cominetti Roberto , Correa José , Larré Omar 
Published: March 2015

Flows over time provide a natural and convenient description for the dynamics of a continuous stream of particles traveling from a source to a sink in a network, allowing to track the progress of each infinitesimal particle along time. A basic model for the propagation of flow is the so-called fluid queue model in which the time to traverse an edge is composed of a flow-dependent waiting time in a queue at the entrance of the edge plus a constant travel time after leaving the queue. In a dynamic network routing game each infinitesimal particle is interpreted as a player that seeks to complete its journey in the least possible time. Players are forward looking and anticipate the congestion and queuing delays induced by others upon arrival to any edge in the network. Equilibrium occurs when each particle travels along a shortest path. This paper is concerned with the study of equilibria in the fluid queue model and provides a constructive proof of existence and uniqueness of equilibria in single origin-destination networks with piecewise constant inflow rate. This is done through a detailed analysis of the underlying static flows obtained as derivatives of a dynamic equilibrium. Furthermore, for multicommodity networks, we give a general nonconstructive proof of existence of equilibria when the inflow rates belong to Lp.
Italian fathers' experiences of labour pain
Authors: Tarlazzi Elena , Chiari Paolo , Naldi Enrico , Parma Dila , Jack Susan M 
Published: March 2015

Background: Most women in Italy ask the father of their baby to be with them during labour. While the benefits on labour outcomes related to the presence of a support person, specifically the infant's father, have largely been demonstrated, few studies have focused on the meaning of this experience for fathers who chose to be with their partners during labour. Despite growing literature on this topic, no study has been conducted in Italy. Methods: The objective of the study is to explain the meaning of the labour pain experience from the father's point of view. The chosen research method was phenomenology. The study involved six fathers. Data collection was conducted through in-depth interviews, until data saturation was reached. Data analysis was conducted using Colaizzi's method. Strategies for increasing trustworthiness were used, such as member checking, peer examination, and code and recode procedures. Results: Five core themes emerged to describe fathers' experiences, including: 1) ‘labour pain is something you have to go through’; 2) a silent presence that gives courage; 3) ‘I hope I can stay until the end of the birth’; 4) ‘I didn't know that would happen’; and 5) fathers' need to ‘recharge their batteries'. Conclusion: Fathers, or partners, are an important resource for women during their labour. However, it is important to prepare men for this role and to provide anticipatory guidance on what to expect during labour. It is important to recognise that the partner may need support or guidance from the midwife during labour. Dissemination of these findings to fathers will also help them to know that their feelings and experiences are common and shared by others.

Horis, neffs and aunties: Social media, language and identity for young Ma-ori in Australia
Authors: Harwood Aramiha 
Published: March 2015

Abstract
With more than 140,000 ‘Mozzies’ (Ma-ori Aussies) living in Australia, people of Ma-ori ancestry constitute Australia’s largest Polynesian ethnic group. One in six of all Ma-ori leave New Zealand (Aotearoa) indefinitely to live and work in Australia. Ma-ori who make this journey encounter difficulties in maintaining cultural traditions, missing extended family (whanau), feelings of difference with both the general population of Australia and Ma-ori back at home, and a variation of expectations of returning home. Many of these issues are expressed in the New Zealand television series The GC (2012) – a Jersey-shore type docu-drama covering the lives of several young Ma-ori based on the Gold Coast in Queensland, Australia. A closer analysis of the members of The GC highlights the diversity of life experiences and cultural understanding amongst them, with agreement not even reached on their self-definition as Mozzies. Similarly, the social media language of young Ma-ori in Australia, when deconstructed, provides a veritable melting-pot of ‘flavours’ and influences. I argue that young Ma-ori Australians provide an important view into the Mozzie experience as they are a large part of the Mozzie population in Australia. Furthermore, they are more likely to experience and question elements of belonging and identity in relation to their Ma-oritanga/culture in the context of an Australian upbringing. Based on a survey of twelve Mozzie participants, I found that Ma-ori language use in social media among them incorporated a mix of English, Ma-ori te reo/Ma-ori language), text-speak and slang, which reflected a similar hybridization of language to that adopted by the young Ma-ori Australian actors on The GC. The aim of this article is to examine this social media language and explore the cultural, generational, technological and social factors influencing its organic growth amongst users. I suggest that this social media language is revealing of the range of experiences of young Ma-ori in Australia – expressing their attempts to maintain close links with Ma-ori culture (Ma-oritanga) and whanau from home, while also establishing a hybridized identity in Australia.
Identity and belonging: Saudi female international students and their use of social networking sites
Authors: Binsahl Haifa , Chang Shanton , Bosua Rachelle 
Published: March 2015

Abstract
This article explores the ways in which Saudi female international students (SFIS) in Australia use social networking sites (SNS) to help them form social networks and present their online identity. Based on themes derived from five in-depth interviews, findings suggest that SFIS use SNS in a way that helps them foster a sense of belonging and connectivity regardless of their location. Currently SFIS use Facebook mainly to keep in touch with friends and family that are both local and international; gain knowledge of the various social and political events happening around them; and have ‘fun’. Similar to findings in the literature on social media use by students, SFIS form distinct virtual social networks made up not only of their conational Saudi friends, but also international Saudi as well as Australian and international friends whom they have face to face contact within Australia. As their main purpose of using SNS was to keep in touch with friends, SFIS reported using their real and accurate identity to make it easy for friends to find them. However, when it comes to the online sharing of personal photos SFIS showed a negative attitude towards posting their personal photos due to cultural considerations. Overall, findings of the study align with the literature in which SNS such as Facebook are instrumental for SFIS in maintaining a strong sense of connectivity and bonding while they are temporarily out of their home country.
The Celtic Tiger ‘Unplugged’: DV realism, liveness, and sonic authenticity in Once (2007)
Authors: Johnston Nessa 
Published: March 2015

Abstract
Once (2007) is described by its director Carney as ‘a modern day musical’, eschewing the elaborately staged set-pieces associated with the film musical genre in favour of a more intimate style in which the songs arise ‘naturalistically’. Depicting the friendship between two musicians towards the end of ‘Celtic Tiger’-era Dublin, the film won critical acclaim and commercial success worldwide, confounding expectations of such a low-budget feature, shot cheaply on digital video. The commercial success of Once exemplifies the ‘rags-to-riches’ heroics of shoestring feature production in the millennial digital era. Yet the narrative of Once is paradoxically uneasy with digital technology and instead articulates what Philip Auslander (and others) term ‘rock authenticity’, fetishizing the ‘live’, the ‘lo-fi’ and the ‘acoustic’ in music. The overall approach to the sound of the film aspires towards ‘liveness’, as the use of location sound recording for the song sequences provides a particular textural quality that incorporates background noise and environmental reverberation, or ‘materializing sound indices’. This article uses analysis of the construction of sound space and sound-image relations in Once to demonstrate how this formal approach works with the narrative to communicate texturally a particular notion of ‘authenticity’ and ‘liveness’ of the film. This will be supplemented with analysis of discourses of authenticity used in the film’s publicity.

Catalyzing decarboxylation by taming carbon dioxide
Authors: Kluger Ronald 
Published: March 2015

AbstractDecarboxylation reactions on enzymes are consistently much faster than their nonenzymic counterparts. Examination of the potential for catalysis in the nonenzymic reactions revealed that the reaction is slowed by the failure of CO2to be launched into solution upon C–C bond cleavage. Catalysts can facilitate the reaction by weakening the C–CO2H bond but this is not sufficient. Converting the precursor of CO2into a precursor of bicarbonate facilitates the forward reaction as does protonation of the nascent carbanion.

Abstract
In the present work, the solid–liquid–liquid equilibrium in the binary system of diethylamine (1) and ionic liquid (2) 1-methyl-3-ethylimidazolium bis(trifluoromethylsulfonyl)imide and solid–liquid equilibrium in system 1-methyl-3-butylimidazolium bis(trifluoromethylsulfonyl)imide was studied. Phase equilibrium was determined experimentally by means of a polythermic method. These data were then used to determine the activity coefficients for both ionic liquids. For the pure diethylamine the enthalpy of fusion was determined by differential scanning calorimetry, because to the best of our knowledge, this data is not yet reported in the open literature, a contrario of pure ionic liquids tested during this work.
