Exploring smartphone social networking services for mobile tourism

Through advanced mobile technologies, multi-functionalities offered by smartphones are emerging for people to use during travel. Under this circumstance, smartphone users can promptly receive information and accordingly adjust travel plans. Such scenario can be extended to social networking services (SNS) for accessing and sharing information on-the-go. However, there is little research in such mobile SNS context. This study aims to investigate the mobile users' willingness to specifically trust travel advice obtained from smartphone SNS, by conducting a quantitative survey to explore factors influencing users' trust on travel advice acquired from smartphone SNS (TTAASS). Our findings show that both perceived value of smartphone SNS (PVSS) and enjoyment of SNS activity (ESA) significantly influence TTAASS, mobile users' smartphone experience significantly affects ESA and PVSS, ESA significantly affects PVSS and facilitating conditions significantly affect ESA. These findings can help managers harvest the benefits of mobile social commerce in the ubiquitous commerce environment.
Effects of dipole–dipole interaction between cigar-shaped BECs of cold alkali atoms: towards inverse-squared interactions

We show that the dipole-dipole coupling between Wannier modes in cigar-shaped Bose-Einstein condensates (BECs) is significantly enhanced while the short-range coupling strongly suppressed. As a result, the dipole-dipole interaction can become the dominant interaction between ultracold alkali Bose atoms. In the long length limit of a cigar-shaped BEC, the resulting effective one-dimensional models possess an effective inverse squared interacting potential, the Calogero-Sutherland potential, which plays a fundamental role in many fields of contemporary physics; but its direct experimental realization has been a challenge for a long time. We propose to realize the Calogero-Sutherland model in ultracold alkali Bose atoms and study the effects of the dipole-dipole interaction.

RNA-Seq reveals the dynamic and diverse features of digestive enzymes during early development of Pacific white shrimp Litopenaeus vannamei

The Pacific white shrimp (Litopenaeus vannamei), with high commercial value, has a typical metamorphosis pattern by going through embryo, nauplius, zoea, mysis and postlarvae during early development. Its diets change continually in this period, and a high mortality of larvae also occurs in this period. Since there is a close relationship between diets and digestive enzymes, a comprehensive investigation about the types and expression patterns of all digestive enzyme genes during early development of L. vannamei is of considerable significance for shrimp diets and larvae culture. Using RNA-Seq data, the types and expression characteristics of the digestive enzyme genes were analyzed during five different development stages (embryo, nauplius, zoea, mysis and postlarvae) in L. vannamei. Among the obtained 66,815 unigenes, 296 were annotated as 16 different digestive enzymes including five types of carbohydrase, seven types of peptidase and four types of lipase. Such a diverse suite of enzymes illustrated the capacity of L. vannamei to exploit varied diets to fit their nutritional requirements. The analysis of their dynamic expression patterns during development also indicated the importance of transcriptional regulation to adapt to the diet transition. Our study revealed the diverse and dynamic features of digestive enzymes during early development of L. vannamei. These results would provide support to better understand the physiological changes during diet transition.
Generation of quantum multi-phonon states in a mechanical oscillator

The main objective of the QuPhon research action is to develop a novel hybrid quantum system between a mechanical oscillator and a superconducting qubit, especially focusing on the generation of nonclassical multi-phonon states in an ultra high-Q mechanical oscillator. The challenging task will be realized by utilizing itinerant microwave photons transferring nonclassical states in a microwave memory cavity to a mechanical oscillator. The architecture of connecting spatially separated quantum modules that function differently enables one to exploit their complementary advantages simultaneously. The achievements will bridge independently-developed quantum technologies between electromechanics and circuit quantum electrodynamics, which will lead to further quantum applications, such as quantum memory and quantum transducer with hardware-efficient quantum error corrections, as well as studies on quantum coherence between two macroscopically distinct states in a massive object.

Overall Stability Analysis of the Olympic Landscape Tower

The Olympic landscape tower locates in the centre area of Beijing Olympic Park. It's beside the south of North Xindian Village Road. The main building closes to the axis of the landscape Avenue. The building is consisted of 5 single- towers with different diameter and height connected by steel trusses. Each tower is composed of cylindrical body and the crown formed top with landscape hall and platform. The maximum height of single-towers is 244.35m. This structure is a kind of flexible high-rise structure. According to the relevant design specifications, the overall stability of the flexible high- rise structure should be checked. Stability analysis refers to the response of structural capacity when the second-order effects are considered. Discussing the influence of geometric non-linearity under lateral load, the stability of the structure and the effective length of the components separately, the results show that for this multi-tower combined structure, the geometric nonlinear effect is not obvious, the problem of overall instability does not exist and the main components are controlled by material strength. These results could be used as design references in similar projects in the future.
Ruminal Solubility and Effect of Calcite Powder Supplementation on Dairy Animal Performance

Ruminal Solubility of Certain Calcium Sources such as calcium carbonate, calcite, dolomite, lime stone powder and dicalcium phosphate (DCP) powder was investigated. Solubility of these calcium sources was low at pH 7 and ranged from 1.74 ± 1.36 in Dolomite to 2.94 ± 0.95 percent in Dicalcium phosphate (DCP). Reducing the pH of the ruminal buffer at 6 increased their solubility and the pattern was almost similar to that recorded at pH 7. Further reduction of pH of ruminal buffer to 2.5, increased their solubility significantly (up to 72.63%), however, Ca solubility of calcium carbonate and dolomite was lower than the other calcium supplements. It was concluded that calcite and lime stone powders may be good source of Ca under the conditions when ruminal pH is towards lower side.
Water stored in cisterns of vulnerable communities in the region of Mato Grande/Rio Grande do Norte: Quality analysis and proposals for viable social technologies.

This article aims to assess the quality of water stored in cisterns, particularly in houses in the Mato Grande Region, an area in Rio Grande do Norte, Brazil, which has benefited from social government programs. Firstly, a survey was applied to the local population to collect information about the stored water (origin, uses, and treatment methods performed). Subsequently, water samples were collected to perform microbiological analyses. The results show that water is primarily used for many purposes, including drinking. Also, all samples were contaminated by Escherichia coli, a fecal coliform bacterium responsible for many diseases and health problems. These findings suggest the urgent need for public policies and investment in technologies, education, and social development to prevent the proliferation of pathogens in the reservoirs. In addition, the article discusses the most viable alternatives to ensure potable water consumption in disadvantaged populations: the development and large-scale implementation of low-cost intervention methodologies, for example, Social Technologies (TS), that are currently discussed in Brazil by different sectors. Through these actions, a plausible solution is being demonstrated to assist with social needs and, as a result, allow the effective reduction of the social exclusion of individuals in complete alignment with the different pillars of sustainable development established by the United Nations Organization (UN).
A Critical Review of Research on the Economic Valuation of Libraries

The value of the library has always been recognized positively. Economic valuation of libraries and their services uses a concrete methodology that enables the quantification of library value and communication of said value among library stakeholders. This paper presents a comprehensive review of literature on economic valuation of the library based on a total of 89 studies conducted over the last quarter-century. Research on library valuation began in the mid-1990`s with the formal exploration of the value of public libraries from a theoretical point of view. In the 2000`s, various theories and methodologies were reviewed and put into actual measurement studies. The comprehensive review and analysis point to the need for the development of consistent and reliable set of methods, which will facilitate further application of methods and comparison of results.
Engineered multi-scale carbon materials

Over the past years, industrial interest in carbon particles such as carbon nanotubes (CNTs) and graphene has resulted in low cost mass production of these materials at low cost. For commercialization purposes it was essential to integrate these new materials with existing high-throughput manufacturing methods such as injection moulding. Unfortunately, these processes result in un-organized CNT arrangements whose figures of merit typically drop by an order of magnitude compared to what is measured in individual nanoparticles. 

Some of the most promising future applications of CNTs and graphene, such as high density energy storage and water filtration however require engineering of order, morphology, and porosity at several length scales to create highly ordered 3D structures. In this project, we propose a new process which assembles CNTs and/or graphene into microstructures using microfluidic emulsification followed by large area self-assembly into colloidal crystals. This approach provides a novel scalable route to sequentially engineer nano-, micro-, and macroscale material architecture. The ability to engineer multi-scale material structure will be harnessed to fabricate new high performance water filtration devices. Further, this project will impact other diffusion limited processes such as energy storage, catalysis, and photovoltaics.
A functional analytic approach for the analysis of nonlinear transmission problems

The purpose of the research plan is the development of the method called Functional Analytical Approach (FAA) for the analysis of singular perturbations of nonlinear transmission problems. The techniques proposed are based on potential theory and functional analysis and aim at describing the effect of perturbations in terms of real analytic functions. Both perturbations of the shapes of the domains of definition and of the coefficients of the operators will be considered.  A special attention will be paid to the case of perforated and periodically perforated domains with shrinking holes and inclusions. The problems addressed are of interest also in view of inter-sectorial applications to the analysis of physical models in fluid dynamic, in elasticity, and in thermodynamic. Concrete applications will be shown in the study effective properties of composite materials, in inverse problems in acoustic and electromagnetic scattering, and in inclusion detection problems. The results obtained represent a novelty with respect to the existing literature for the following reasons:

•	the techniques of FAA are innovative with respect to the classical approaches existing in literature and allow the implementation of analytic functions in the description of the effect of perturbations;  

•	we treat non-linear boundary value problems and transmission problems, which are relevant in application and present challenging difficulties; 

•	we will obtain new results of pure mathematics in the frame of potential theory.  In particular we will study the analyticity of certain nonlinear integral operators related to the layer  and volume potentials;

•	we will show how to obtain explicit calculations and we will show concrete applications in continuum mechanics. 

The final goal within the action is the realisation of a complete theory based on the FAA which will represent in future a key tool for the analysis of perturbed boundary value problems.

Computational model of matrix remodeling and entrenchment in the free-floating fibroblast-populated collagen lattice

Tissue equivalents represent excellent model systems for elucidating principles of mechanobiology and for exploring methods to improve the functionality of tissue-engineered constructs. The simplest tissue equivalent is the free-floating fibroblast-populated collagen lattice. Although introduced over 30 years ago, the associated mechanics of the cell-mediated compaction of this lattice was only recently analyzed in detail. The goal of this paper was to build on this recent stress analysis by developing a computational model of the evolving geometry, regionally varying material properties and cell stresses, and overall residual stress fields during the first two days of compaction. Baseline results were found to agree well with most experimental observations, namely evolving changes in radius, thickness, and material symmetry, yet hypothesis testing revealed aspects of the mechanobiology that require more experimental attention. Given the generality of the proposed framework, we submit that modifications and refinements can be used to study many similar systems and thereby help guide future experiments.
Design of Embedded OS Micro-kernel Experiment Series on ARM

This paper describes technical details of designing an embedded OS micro-kernel experiment series on ARM platform for embedded curriculum teaching. The series consists of several step by step foundational experiment projects for designing a micro-kernel embedded operating system, mainly including self-adapted built-in boot loader, UART and formatted display, MMU and hardware interrupt, software interrupt, and multi-tasking schedule, implemented in five experiment projects. The final project is in fact already an embryonic form of an embedded operating system micro kernel. It can be used in embedded curriculum teaching to provide a real example for students to learn and study. Based on this experiment series, the students can expend the system further, for example, with inter-task communication, file system, TCP/IP protocol, etc., to implement a real micro kernel embedded operating system.
Sanctuary or double-edged sword? Challenges confronting adolescents living at Nkosi's Haven in Johannesburg, South Africa

Living in an institution associated with HIV and AIDS is likely to exacerbate difficulties experienced by teenagers who have to cope with the normal stresses of adolescence. The aim of the study was to explore the challenges that adolescents living at Nkosi's Haven encounter and whether they experience any problems when interacting with their peers and other members of the community. The study was located within a qualitative research paradigm and utilised a purposive, non-probability sample of 15 participants recruited from two Nkosi's Havens. A semi-structured interview schedule was employed as the research tool, with in-depth one-on-one interviews adopted as the method of data collection. Thematic content analysis was used to analyse the data collected during the interviews. The main finding that emanated from the study was that Nkosi's Haven is indeed a place of care and nurturing as adolescents are afforded the opportunity to continue with their educational needs while basic and psychosocial needs are also addressed. However, it also emerged that rejection, discrimination, social exclusion and stigmatisation associated with the setting make it difficult for resident adolescents to integrate freely with their peers at school and in the community. The conclusion drawn is that Nkosi's Haven can be regarded as a double-edged sword as it presents both positive and negative factors that impact on its resident adolescents. Results are discussed in terms of their implications for community awareness programmes, policies and practice changes regarding employment and training of staff, and visiting of parents as well as future research.
STAT transcript levels in childhood acute lymphoblastic leukemia: STAT1 and STAT3 transcript correlations

We investigated the transcript levels of genes STAT1, STAT3, STAT5A and STAT5B in the diagnostic samples of childhood ALL patients and compared them to those of healthy controls in order to characterize STAT gene expression in childhood ALL. As compared to controls, ALL patients exhibit markedly decreased transcript levels in all four genes investigated. STAT1 and STAT3 are significantly correlated in ALL patients as opposed to controls (P<0.0005). Patients with low transcript levels of STAT1 and STAT3 survive, regardless of minimal residual disease status and relapse. Lower transcript levels appear in association with a particularly high survival outcome in the ALL patients. The identification of aberrant expression profiles provides insight into the role of STAT genes in the development of childhood ALL and enables development of patient-tailored therapeutic approaches in cases of resistant disease.
Suppression of Rice Immunity by Xanthomonas oryzae Type III Effector Xoo2875

Xanthomonas oryzae delivers effector proteins into host cells through a type III secretion system to inhibit host immune responses, but how these effectors suppress host immunity is largely unknown. Here we found that Xoo2875, one of the effectors of X. oryzae, strongly inhibited host resistance to X. oryzae. Transgenic rice plants expressing Xoo2875 exhibited semi-dwarfism and a reduction in Brassinolide-dependent laminar inclination, characteristics of brassinosteroid (BR)-insensitive mutants caused by mutations of the BR receptor. A yeast two-hybrid experiment indicated that Xoo2875 interacted with OsBAK1, an essential component of both microbe-associated molecular patterns (MAMPs) and BR receptors, suggesting that the virulent activity of Xoo2875 is mediated by inhibition of OsBAK1. Expression of Xoo2875 in Arabidopsis cells activated host immune responses, suggesting the presence of intracellular immune receptors that recognize Xoo2875. Because Xoo2875 homologs are highly conserved in Xanthomonas species, the development of Xoo2875-induced immunity is probably a useful strategy to avoid pathogen invasion.
ADJUSTABLE TABLE FOR ORTHOPEDIC SURGERY AND TECHNIQUES FOR IMPLANTING A VERTEBRAE IMPLANT

An adjustable table allows for improved access to a patient during surgery, such as vertebrae implant surgery. The table comprises a base, a support towers mounted in a spaced-apart relation on the base, a table for holding a patient's body, and spaced-apart pairs of body support assemblies to fix in place parts of the patient's body. The table is pivotably mounted between the support towers to be rotatable about a longitudinal axis, allowing the patient to be turned from a prone to a lateral or supine position. The spaced-apart pairs of body support assemblies are configured to clamp a part of a body to fix the position of that part, thereby holding the patient to the table when rotated, and allowing the patient's body to be fixed in a desired position.
