An Area Content Distribution Scheme Based on Local Response Service for Vehicular Ad Hoc Networks

Disseminating content to a specific geographical area and keeping for a period of time for high dynamic Vehicular ad hoc network( VANET) is a challenge task. A local response service( LRS) based area content distribution scheme is proposed. The scheme codes the distributing content with random linear network coding and caches it to the mobile vehicles within the service area randomly so that all the requests from the nodes located in the service area can be serviced by any surrounding neighbors. NS-3 simulation results show that the scheme can reduce the distribution delay effectively and consequentially improve the delivery ratio of the system.

AtMyb7, a subgroup 4 R2R3 Myb, negatively regulates ABA-induced inhibition of seed germination by blocking the expression of the bZIP transcription factor ABI5.

Various Myb proteins have been shown to play crucial roles in plants, including primary and secondary metabolism, determination of cell fate and identity, regulation of development and involvement in responses to biotic and abiotic stresses. The 126 R2R3 Myb proteins (with two Myb repeats) have been found in Arabidopsis; however, the functions of most of these proteins remain to be fully elucidated. In the present study, we characterized the function of AtMyb7 using molecular biological and genetic analyses. We used qRT-PCR to determine the levels of stress-response gene transcripts in wild-type and atmyb7 plants. We showed that Arabidopsis AtMyb7 plays a critical role in seed germination. Under abscisic acid (ABA) and high-salt stress conditions, atmyb7 plants showed a lower germination rate than did wild-type plants. Furthermore, AtMyb7 promoter:GUS seeds exhibited different expression patterns in response to variations in the seed imbibition period. AtMyb7 negatively controls the expression of the gene encoding bZIP transcription factor, ABI5, which is a key transcription factor in ABA signalling and serves as a crucial regulator of germination inhibition in Arabidopsis.

Expansion of the aspartate beta-semialdehyde dehydrogenase family: the first structure of a fungal ortholog.

The enzyme aspartate semialdehyde dehydrogenase (ASADH) catalyzes a critical transformation that produces the first branch-point intermediate in an essential microbial amino-acid biosynthetic pathway. The first structure of an ASADH isolated from a fungal species (Candida albicans) has been determined as a complex with its pyridine nucleotide cofactor. This enzyme is a functional dimer, with a similar overall fold and domain organization to the structurally characterized bacterial ASADHs. However, there are differences in the secondary-structural elements and in cofactor binding that are likely to cause the lower catalytic efficiency of this fungal enzyme. Alterations in the dimer interface, through deletion of a helical subdomain and replacement of amino acids that participate in a hydrogen-bonding network, interrupt the intersubunit-communication channels required to support an alternating-site catalytic mechanism. The detailed functional information derived from this new structure will allow an assessment of ASADH as a possible target for antifungal drug development.

[Cognitive behavioral therapy of residual symptoms in patients with juvenile depression].

There were forty patients (mean age 20.7 years) who met the ICD-10 criteria of diagnosis of affective disorder (items F31-F33)--juvenile depression, successfully treated with antidepressants in psychiatric hospital and later on maintenance therapy for correction of residual symptoms. The duration of follow-up study was 2 years. All the patients were randomised into two groups, the first one receiving psychopharmacotherapy combined with cognitive behavioural therapy and the second--only the former one. In both groups, the antidepressant dosing was continuously decreased up to complete withdrawal. In the first group, patients revealed significantly fewer residual symptoms after antidepressants treatment compared with the second group, which was assigned only to psychopharmacotherapy. Also, depression relapse frequency tended to be lower in the first group than in the second one (15% vs 35%) but the differences were insignificant. The authors emphasize that further studies of cognitive behavioural therapy in depression relapse prevention are needed.

Air Passengers’ Continued Use Intention of the Airport E-Gate System: A Perspective with Perceived Beneﬁts

With the rapid development of air transportation in recent years, the number of national entry and exit passengers has hit record highs. Facing the increasingly busy airport, an automated border control system (E-gate) has been developed to provide faster and more convenient services. This study adopts the perspective of perceived benefits to explore the willingness of passengers to continuously use the E-Gate. In this study, a total of 539 valid questionnaires are collected at the Taoyuan International Airport in Taiwan. The SPSS 24 and AMOS 22 software are used for statistical analysis, and the hypotheses are verified by Structural Equation Modeling (SEM). The results show that perceived ease of use, perceived usefulness, and convenience have positive and significant effects on air passengers’ continued use intention of E-gate, with convenience having the greatest impact, followed by perceived ease of use and perceived usefulness. The findings of this research can not only assist government agencies and airport operators in the development of better user-accepted immigration clearance systems, but can also provide insight into how to promote the new technology to potential users.

The good, the bad and the ugly: science, aesthetics and environmental assessment

The question is raised, whether there are peculiarly scientific values which can be applied in environmental assessment. The use of the expression ‘scientific interest’ is traced from its 19th century origins to modern British statutes. It is argued that attempts to replace expert judgements by objective scientific criteria (e.g., indices of biodiversity) can never be completely successful. In particular, ‘interest’ is an aesthetic atribute particularly valued by scientists but incapable of precise measurement. While science provides the best framework for informed judgements on conservation issues, the judgements of scientists are inevitably distinct from their experimental results. Judgements rest on ethical and aesthetic values such as importance and interest, which are essential constituents of the scientific sub-culture, but which are not uniquely ‘scientific”.

The Local South American Chicken Populations Are a Melting-Pot of Genomic Diversity

Chicken have a considerable impact in South American rural household economy as a source of animal protein (eggs and meat) and a major role in cultural traditions (e.g., cockfighting, religious ceremonies, folklore). A large number of phenotypes and its heterogeneity are due to the multitude of environments (from arid to tropical rain forest and high altitude) and agricultural systems (highly industrialized to subsistence agriculture). This heterogeneity also represents the successive introduction of domestic chicken into this continent, which some consider predating Columbus’ arrival to South America. In this study, we have used next-generation restriction site-associated DNA sequencing to scan for genome-wide variation across 145 South American chickens representing local populations from six countries of South America (Colombia, Brazil, Ecuador, Peru, Bolivia, and Chile). After quality control, the genotypes of 122,801 single nucleotide polymorphisms (SNPs) were used to assess the genomic diversity and interpopulation genetic relationship between those populations and their potential sources. The estimated population genetic diversity displayed that the gamefowl has the least diverse population (θπ = 0.86; θS = 0.70). This population is also the most divergent (FST = 0.11) among the South American populations. The allele-sharing analysis and the admixture analysis revealed that the current diversity displayed by these populations resulted from multiple admixture events with a strong influence of the modern commercial egg-layer chicken (ranging between 44% and 79%). It also revealed an unknown genetic component that is mostly present in the Easter Island population that is also present in local chicken populations from the South American Pacific fringe.

Production of carotenoids by recombinant DNA technology

Biotechnology can be used to effect the production of carotenoids by natural organisms. Algae and yeast strains have been developed by classical strain improvement methods to produce several different carotenoids. However, the carotenoid productivity of these organisms is low compared to carotenoid production by chemical synthesis. One way to increase the production of carotenoids in biological systems is to use recombinant DNA techniques. The carotenoid biosynthetic pathway is especially amenable to manipulation by recombinant DNA techniques since all carotenoids share a common precursor. Effecting these key steps with genetic engineering methods can increase carotenoid productivity. In addition natural systems have a very widespread biosynthetic capability, and these systems can be used to synthesize novel carotenoids for particular applications. Recently, many genes coding for enzymes catalyzing specific steps in the biosynthesis of carotenoids have been isolated and characterized from bacteria, cyanobacteria, and higher plants. This paper will focus on the application of carotenoid biosynthetic genes to affect carotenoid production in bacteria and yeasts. I NTRO DUCT1 0 N Carotenoids are produced by a diverse group of organisms, ranging from bacteria to higher plants. Over 600 different carotenoids have been identified from natural sources. This biological diversity and synthetic capability have not been exploited to develop systems for the production of carotenoids. Currently only P-carotene and astaxanthin are produced from biological sources and sold widely to the food and feed industries. The key limitation to the use of biological systems to produce carotenoids is the low productivity of these systems compared to chemical syntheses. One way to increase the productivity of carotenoid synthesis is to use recombinant DNA technology. However, before recombinant DNA technology and genetic engineering can be used to increase the productivity, genes encoding the carotenoid biosynthetic enzymes need to be isolated and characterized. Until very recently, genes for the carotenoid biosynthetic enzymes had not been isolated. This situation has changed markedly over the past three years. Currently a number of the genes coding for carotenoid biosynthetic enzymes have been isolated from bacteria, fungi, cyanobacteria, green algae, and higher plants (Table 1 I . With the large number of genes now available for further study, systems can be tested to increase the production of carotenoids from biological sources. Results from these studies will fuel the development of processes for the production of carotenoids from a number of different host organisms and the full range of carotenoid compounds from biological sources will be accessible. The following will describe the characterization of carotenoid genes from Erwinia herbicola and the use of these genes to effect carotenoid synthesis in different host cells.

Transformation of Manufacture Format,Compositive Economy and Upgrading for International Model

In recent years,more and more enterprises came to collaborate with each other,and the enterprises put more emphasis on decomposing and combining profit chain.The motivation of the above actions has no difference.They try their best to slice the market in order to gain compositive economy.Compositive economy came from two resources.On one hand,under the condition of no changes of producing scale and technology level,enterprises split one value chain,or rearrange their branches through joint venture or sole venture so as to gain the income by making full use of different marginal productivity;on the other hand,enterprises seek more trading business to obtain the advantages coming from market density through global outsourcing,OEM and some other none share right.This paper tries to build an analyzing frame about compositive economy, by means of which explain the reason why some new organizing methods of producing such as supply chain,outsourcing,modulation,downsizing,network between enterprises have accepted broadly.The paper also tries to explain the reason why enterprises and the micro mechanism of international industry transfer,puts forward the different ways of "breeding exiguous producing elements"and deepening global value chain to impel"international increase model".

Prevalence of Listeria monocytogenes in frozen burger patties in Malaysia

A total of 112 burger patties (35 beef burger patties, 39 chicken burger patties and 38 fish burger patties) which are commercially available at retail level were investigated for the presence and number of Listeria monocytogenes. These samples were analyzed using MPN-PCR method and conventional culturing methods. L. monocytogenes was detected in 33.3% of chicken burger patties, 22.9%of beef patties, and 10.5% of fish patty samples. From all contaminated raw burger patties, the estimated count of L. monocytogenes was ranged from 3 to 75 MPN/g. The results suggest that burger act as a potential source of listeriosis if the contaminated burger patty is consumed without adequate cooking. The risk associated with consumption of these samples was found to be high particularly for processed food at retail level in Malaysia. Therefore, food manufacturers play an importantrole in monitoring the manufacturing process and conduct a periodical surveillance on microbiological quality assessment on the processing plants. Besides, there is a need to increase awareness ofconsumers and food handlers to practice proper cooking of the burger patties before the point of consumption, to reduce the risk of listeria infection.

Precocious puberty in McCune-Albright syndrome: a case report

McCune-Albright syndrome (MAS) is a rare disease characterized by a triad of fibrous dysplasia, cafe-au-lait spots and peripheral precocious puberty. We reported a 5-year- 8-month old girl with MAS who has been followed-up for 2 years and 8 months. She was referred to pediatric endocrinology clinic in our hospital for vaginal bleeding at age of 2 years 11 months. She had peripheral precocious puberty, i.e. increased estrogen level associated with very low gonadotropins, and cafe-au-lait spots on her face and was diagnosed as MAS. The patient was treated with estrogen receptor blocker (tamoxifen). She had no menses during the 2 years and 8 months of tamoxifen treatment. Her growth rate and bone maturation were also in normal ranges. However, at the end of tamoxifen treatment she had an episode of vaginal bleeding so that we had to change to other treatment modalities.

Analysis of performance and economical efficiency of two-stage compression heat pump system with inter-stage injection in cold regions of northern China

The low temperature adaptability of air source heat pump in the field of building heating in cold regions has always been a hot topic. At present, the combination of inter-stage injection technology and two-stage compression can effectively solve the problem of low temperature adaptability. Therefore, in the present paper, the two-stage compression heat pump system with inter-stage injection was taken as the research project. Based on the simulation model of the two-stage compression heat pump system, the process of inter-stage injection coupling between the low-stage compressor and the high-stage compressor was analyzed. Based on the experimental results, the effects of inter-stage injection process on the inter-stage pressure, inter-stage temperature and thermal performance parameters of the two-stage compression system were analyzed. The results show that as the mass of inter-stage injection increases, the inter-stage pressure will increase significantly and then increase slowly; and the inter-stage temperature will increase slowly and then decrease significantly; both the heat output and the COP will increase first and then slightly decrease. In addition, the heat output will increase by about 8%–15%, and the COP will increase by about 5%–12%. Finally, the two regions including Beijing and Dalian in China were selected, and the economical efficiency of the system in applications was analyzed in combination with the experimental results of variable working conditions of the system.

Experimenting locally with a stepped-care approach for the treatment of mild to moderate mental disorders in France: Challenges and opportunities.

In France, publicly funded mental care services are mostly hospital-based and focused on treating severe illnesses. Mild to moderate mental disorders are typically managed by general practitioners (GP) who often lack specific training to treat these conditions. Antidepressant prescribing levels for mild to moderate conditions are inadequately high. Public reimbursement for psychotherapies provided by psychologists is generally not available. This paper presents a local experiment with a stepped-care approach for the treatment of mild to moderate mental disorders in four French départements launched in 2018. The experiment includes the introduction of a standardized assessment protocol for GPs, clear referral guidelines, and full reimbursement of visits to psychologists upon GP referral. Seemingly simple, the policy raises several issues related to the regulation, training and reimbursement of psychologists, and illustrates the need for careful preparation and workforce planning to ensure success and stakeholder support. An independent evaluation of the local experiments is planned, which provides the opportunity to fine-tune the policy before any broader rollout. The issues raised in France and the on-going debate is relevant for other countries preparing similar policies for improving mental care.

Rice Biofortification With Zinc and Selenium: A Transcriptomic Approach to Understand Mineral Accumulation in Flag Leaves

Human malnutrition due to micronutrient deficiencies, particularly with regards to Zinc (Zn) and Selenium (Se), affects millions of people around the world, and the enrichment of staple foods through biofortification has been successfully used to fight hidden hunger. Rice (Oryza sativa L.) is one of the staple foods most consumed in countries with high levels of malnutrition. However, it is poor in micronutrients, which are often removed during grain processing. In this study, we have analyzed the transcriptome of rice flag leaves biofortified with Zn (900 g ha–1), Se (500 g ha–1), and Zn-Se. Flag leaves play an important role in plant photosynthesis and provide sources of metal remobilization for developing grains. A total of 3170 differentially expressed genes (DEGs) were identified. The expression patterns and gene ontology of DEGs varied among the three sets of biofortified plants and were limited to specific metabolic pathways related to micronutrient mobilization and to the specific functions of Zn (i.e., its enzymatic co-factor/coenzyme function in the biosynthesis of nitrogenous compounds, carboxylic acids, organic acids, and amino acids) and Se (vitamin biosynthesis and ion homeostasis). The success of this approach should be followed in future studies to understand how landraces and other cultivars respond to biofortification.
