Effect of dietary protein and genetic line of Litopenaeus vannamei on its

: Host genetics and diet can exert an influence on microbiota and, therefore, on feeding efficiency. This study evaluated the effect of genetic line (fast-growth and high-resistance) in Pacific white shrimp ( Litopenaeus vannamei ) on the hepatopancreatic microbiota and its association with the feeding efficiency in shrimp fed with diets containing different protein sources. Shrimp (2.08 ± 0.06 g) from each genetic line were fed for 36 days with two dietary treatments (animal and vegetable protein). Each of the four groups was sampled, and the hepatopancreatic metagenome was amplified using specific primers for the variable V4 region of the 16S rRNA gene. The PCR product was sequenced on the MiSeq platform. Nineteen bacterial phyla were detected, of which Proteobacteria was the most abundant (51.0 – 72.5 %), Bacteroidetes (3.6 – 23.3 %), Firmicutes (4.2 – 13.7 %), Actinobacteria (1.9 – 12.1 %), and Planctomycetes (1.3 – 9.5 %). Diet was the most influential factor in the taxonomic composition of the microbiota, while genetic line was not a strong influential factor. The results suggest that the taxonomic profile of the bacteria colonizing shrimp hepatopancreas was determined by the diet consumed, similar to what occurs in the intestine. Shrimp in the fast-growth line had greater feeding efficiency regardless of the diet supplied. Finally, the results suggest that Proteobacteria influenced ( p < 0.05) the feeding efficiency of shrimp fed with a vegetable diet. Nevertheless, further studies are required to explore how shrimp genetic line–diet interaction influences microbiota for probiotic development and functional food formulation for farmed shrimp according to the genetic line.
Calculation of the Size of Biomimetics Robots According to Need and Purpose of Use

— In the 4 th industrial revolution era, more countries and companies tend to use specialized robots to replace workers. Especially in a hazardous and high risks working environment, robots that perform human tasks are also hu-manistic. It’s even the unique solution to ensure life safety. Currently, scientists are much interested in robots that look, act like animals; including biomimetic robot models have capable of flexible mobility and widely application potential. However, it’s difficult to calculate, design and manufacture dynamic robots. In this article, the author will present an overview of dynamic robots and propose new methods and calculation techniques to design and build biomimetic robots. The experimental results show that proposals have contributed to solve those dif-ficulties and being practically applicable to make a biomimetic robot.
Understanding memristors and selectors for future storage and computing applications: Modeling and analysis

The memristor and selector devices are the most promising candidates in the research of emerging memory technologies and neuromorphic computing applications. To understand the device properties and guide for future applications, models for those devices based on physical mechanisms are essential. We developed models for two popular memristors and a selector. We developed a SPICE-compatible compact model of TiO2-TiO2-x memristors based on classic ion transportation theory. Our model is shown to simulate important dynamic memristive properties like real-time memristance switching, which are critical in memristor-based analog circuit designs. The model, as well as its analytical approximation, is validated with the experimentally obtained data from real devices. Minor deviations of our model from the measured data are also analyzed and discussed. We illustrate a heuristic two-state-variable memristor model of charged O vacancy drift resistive switches that includes the effects of internal Joule heating on both the electronic transport and the drift velocity (i.e. switching speed) of vacancies in the switching material. The dynamical state variables correspond to the cross-sectional area of a conducting channel in the device and the gap between the end of the channel and one of the electrodes. The model was calibrated against low voltage pulse-sweep and state-test data collected from a TaOx memristor so that the contributions of the channel gap, area and temperature to switching can be analyzed. The model agrees well with experimental results for long switching times and low-to-intermediate voltage operation. A selector device that demonstrates high nonlinearity, low switching voltage and volatility was fabricated using HfOx materials with Ag electrodes. The electronic conductance of such volatile selector device was studied under both static and dynamic conditions, with DC and AC measurements respectively. From experimental observations, a compact model is developed in this study to illustrate the physical process of the formation and dissipation of Ag filament for electron transport through the device. A dynamic capacitance model is used to fit the transient current traces under different voltage bias through the device and allow the extraction of parameters associated with the various parasitic components in the device.
Qubits and their applications in metrology

Now there is a great interest in the field of information technologies cause development a quantum computer that make direct use of quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data. Qubit is a unit of quantum information—the quantum analogue of the classical bit. As a bit, a qubit admits two of its own state, but it can be in superposition. Following the development of a quantum computer will need to establish a standard unit of quantum information. The search for a candidate for the role of the qubit (and, stable) can give perspectives to the development of quantum metrology.
Segmentation of the nuchal fold in fetal ultrasound images

The thickness of the nuchal fold is one of the main markers for the detection of Down syndrome during the second trimester of pregnancy. In this paper are reported our preliminary results of the automatic segmentation and measurement of the nuchal fold thickness in ultrasound images of the fetal brain. The method is based on a 2D active shape model used to segment the brain structures involved in the measurement of the nuchal fold: cerebellum; brain midline; the outer edge of the occipital plate; and the outer skin edge. The algorithm was trained and tested in 10 different ultrasound images, using leave one out cross validation. We have obtained an average difference of 0.23 mm from the expert measurement of the nuchal fold, with a standard deviation of 0.1 mm.
A nomogram model to predict death rate among non-small cell lung cancer (NSCLC) patients with surgery in Surveillance, Epidemiology, and End Results (SEER) database CURRENT STATUS: UNDER REVIEW

This study aimed to establish a novel nomogram prognostic model to predict death probability for non-small cell lung cancer (NSCLC) patients who received surgery. Methods We collected data from the Surveillance, Epidemiology, and End Results (SEER) database of the National Cancer Institute in the United States. A nomogram prognostic model was constructed to predict mortality of NSCLC patients who received surgery. Results A total of 44,880 NSCLC patients who received surgery from 2004 to 2014 were included in this study. Gender, race, tumor anatomic sites, histologic subtype, tumor differentiation, clinical stage, tumor size, tumor extent, lymph node stage, examined lymph node, positive lymph node, type of surgery showed significant associations with lung cancer related death rate (P<0.001). Patients who received chemotherapy and radiotherapy had significant higher lung cancer related death rate but were associated with significant lower non-cancer related mortality (P<0.001). A nomogram model was established based on multivariate models of training data set. In the validation cohort, the unadjusted C-index was 0.73 (95% CI, 0.72-0.74), 0.71 (95% CI, 0.66-0.75) and 0.69 (95% CI, 0.68-0.70) for lung cancer related death, other cancer related death and non-cancer related death. A prognostic nomogram model was constructed to predict death rate for NSCLC patients who received surgery. This novel prognostic model may be helpful for physicians to develop the most appropriate treatment strategies for resected NSCLC patients. Parts of these results were presented at the 2018 anatomic sites, histological tumor differentiation, clinical stage, tumor size, lymph node involvement, examined lymph node (ELNs), positive lymph node (PLNs), chemotherapy and radiotherapy. Categorical variables were grouped for clinical reasons, and the decisions regarding grouping were made before data analysis. Mean, medians and ranges were reported for continuous variables, as appropriate. Frequencies and proportions were reported for categorical variables.

Occurrence and in Vivo Biosynthesis of Indole-3-Butyric Acid in Corn (Zea mays L.)I

Indole-3-butyric acid (IBA) was identified as an endogenous compound in leaves and roots of maize (Zea mays L.) var Inrakom by thin layer chromatography, high-performance liquid chromatography, and gas chromatography-mass spectrometry. Its presence was also confirmed in the variety Hazera 224. lndole-3-acetic acid (IAA) was metabolized to IBA in vivo by seedlings of the two maize varieties. The reaction product was identified by thin layer chromatography, high performance liquid chromatography, and gas chromatography-mass spectrometry after incu-bating the com seedlings with [14C]IAA and [13C6]1AA. The in vivo conversion of IAA to IBA and the characteristics of IBA formation in two different maize varieties of Zea mays L. (Hazera 224 and Inrakorn) were investigated. IBA-forming activity was examined in the roots, leaves, and coleoptiles of both maize varieties. Whereas in the variety Hazera 224, IBA was formed mostly in the leaves, in the variety Inrakom, IBA synthesis was detected in the roots as well as in the leaves. A time course study of IBA formation showed that maximum activity was reached in inrakom after 1 hour and in Hazera after 2 hours. The pH optimum for the uptake of IAA was 6.0, and that for IBA formation was 7.0. The Km value IBA formation was 17 micromolar for Inrakom and 25 micromolar for Hazera 224. The results are discussed with respect to the possible functions of IBA in the plant.
The Determinants of Foreign Direct Investment in Real Estate Market of Turkey: Evidence from a Cointegrated VAR

The aim of the study is to analyze the macroeconomic determinants of foreign direct investment in real estate sector (FDIRE) covering the period from 2003:01-2016:12 for Turkey. To this aim, Johansen cointegration test and VECM (cointegrated VAR) have been employed and also impulse response functions and forecasted error variance decompositions have been analyzed to shed light on the issue of the nexus between selected macroeconomic indicators and FDIRE. Empirical findings suggest that the number of one-year lagged tourist arrivals and real house rent is the most important and statistically significant determinants of foreign direct investment in Turkish real estate sector. The findings imply that real house rent shocks also have a positive and significant impact on real house price.
RESPONSES OF NOVICE DESIGNERS TO UNSTRUCTURED PROBLEMS

The development of novice engineering designers is assisted at the earliest levels by building problem solving skills within well-defined problem domains [1]. These early experiences are structured to provide success measures and build design confidence, but then proceed progressively from the familiar to the unfamiliar. This paper discusses the performance of novice designers when introduced to increasingly unstructured problems, and in particular, those that require creative responses.
Effect of Storage Conditions on Stability of Low Glycemic Index Noodles with Enzymatically Modified Ingredients

Stability of a food product mainly depends on its ingredients. Stable food products have a huge consumer market. In this study, noodles were prepared using enzymatically modified ingredients. The shelf stability of noodles was determined under two different conditions, ambient (27°C, 65% RH) and accelerated (37°C, 92% RH). Samples were withdrawn at particular intervals and analysed for their physico-chemical, in-vitro and in-vivo properties. The properties of stored products were compared with those of initial products. Noodles with enzymatically modified ingredients showed reduced glycemic index (GI) compared to their native forms. Noodles with enzymatically modified ingredients can be stored up to 60 days at an ambient condition without any negative effect on their quality. As the noodles with enzymatically modified ingredient showed promising results with reference to their quality characteristics, it can be beneficial in maintaining the health of the individuals with diabetes mellitus, if supported by in-vivo studies. differently.
Male Wistar strain rats

Comparative morphological studies on epididymal fat cells from young, old and obese rats were made by scanning and freeze-fracture electron microscopies. Scanning microscopy showed that adipocytes of young rats were spherical with a smooth surface, but with a few crater-like pits. As the rats became older, their fat cells increased in size and the surface of the cells became rough with an increase in the number o£ craters. In obese rats, there were more numerous craters in various sizes than in old rats. In ultra-thin sections, the accumulated lipid of adipocytes appeared uniform and amorphous. But in freeze-fractured adipocytes of young and old rats the central lipid was seen to have a multi-lamellar structure, like an onion. The fracture-face of lipid droplets in adipocytes from the obese rat was disfigured and complicated by the crossing of membranous lamellae. These findings suggest that the modes of lipid accumulation in the fat cells of old rats and obese rats differ. This difference may be related to the difference in the distributions and numbers of craters on the surface of adipocytes in these animals.
STUDY OF DIAMINOBENZIDINE OXIDATION BY ISOLATED VICIA CHLOROPLASTS UNDER ILLUMINATION MACHIKO IMAIZUMI AND TOSHISUKE HIRAOKA

A concurrent microchemical and topochemical study of DAB* oxidation by isolated chloroplasts of Vicia faba under illumination was carried out. A new method for the quantification of the oxidation product of DAB was explored. The microchemical analysis by this method revealed that the photosystem responsible for the DAB oxidation was the PS-I. It also proved that endogenous active oxygen in the chloroplasts played only a little role in the oxidation. The topochemical analysis revealed that both the grana and the stroma membrane were positive in DAB photooxidation. The densitometric traces across the grana membranes in both surface and side views proved effective in locating the precise reaction sites. The partition layer showed a high degree of positive reaction. The thylakoid membrane proper also contained particles of positive reaction. The positive site extended to the thylakoid loculus to form protrusions. These results are in harmony with the localization of the PS-I complex particles on the PF face side of the thylakoid membrane as revealed by the freeze fracture technique.
EXPORT PERFORMANCE IN SOUTH AMERICA: DO INTANGIBLES AFFECT FIRMS’ PERFORMANCE IN DEVELOPING COUNTRIES SUCH AS PERU?

This study is one of the first empirical studies on intellectual capital (IC) in South American textile exporting companies. Using the resources and capabilities approach, we examine how certain intangibles can provide competitive advantages. We propose and test a model capturing the relationships between IC components and export performance (EP), as well as the various interrelationships among the different dimensions of IC. Using a sample of textile manufacturers operating in Peru, an emerging economy, we find that both human capital and structural capital have a significantly positive influence on EP. However, the data analysis does not confirm that relational capital has any positive influence on export performance.
p53 Gene Mutation Spectrum in Hepatocellular Carcinoma1

In order to clarify the significance of mutation of the p53 tumor suppressor gene in the genesis and development of human hepatocellular carcinoma (HCC) in an aflatoxin I! , Ion-exposure area, the spec trum, i.e. incidence, type, and site, oipS3 gene mutations was examined in 169 tissue samples resected mainly from Japanese patients using single-strand conformation polymorphism analysis and direct sequenc ing. Forty-nine tumors (29%) showed a p53 mutation (39 point muta tions and 10 frameshifts). The point mutations comprised 18 transitions, only 4 of which occurred at CpG sites, and 21 transversions. Two evo-lutionarily conserved domains, IV and V, contained 65% of all muta tions and codon 249 was the most frequent mutation site (7/49). The spectrum of p53 mutation did not differ among HCCs in relation to the type of hepatitis virus infection, sex, age, and background liver disease of patients, tumor size, or presence of metastasis, but incidence and site were significantly associated with the degree of differentiation of cancer cells. In poorly differentiated HCC, p53 mutation was frequent (54%) and clustered on domains IV and V, whereas in well or moderately differentiated HCC, the mutation was less frequent (21%) and equally distributed on domains II to V. Restriction fragment length polymor phism analysis revealed loss of heterozygosity on chromosome 17p in 55 (69%) of 80 informative cases and in 34 (95%) of 36 cases with pS3 mutation. Therefore, p53 gene mutation is suggested to occur indepen dently of the type of viral infection or status of preexisting liver disease and to occur preferentially in moderately and poorly differentiated HCCs in association with or after loss of another p53 alÃ eleas a late event of HCC progression.

Accelerating Stencil Computation on GPGPU by Novel Mapping Method Between the Global Memory and the Shared Memory

Acceleration of stencil computation can be eﬀectively improved by utilizing the memory resource. In this paper, in order to reduce the branch divergence of traditional mapping method between the global memory and the shared memory, we devise a new mapping mechanism in which the conditional statements loading the boundary stencil computation points in every XY-tile are removed by aligning ghost zone to reduce the synchronization overhead. In addition, we make full use of single XY-tile loaded into registers in every stencil computation point, common sub-expression elimination and software prefetching to reduce overhead. At last detailed performance evaluation demonstrates our optimized policies are close to optimal in terms of memory bandwidth utilization and achieve higher performance of stencil computation.
Comment

Hall and Kudlyak start with the observation that in the typical US business cycle recovery, unemployment declines slowly but reliably from a high point at the end of a business cycle contraction. They show that the direct effect of job loss at the onset of the recession cannot account for the persistently high unemployment rate during the recovery. The recession’s effects on the labor market go beyond the job losses that mark the beginning of recessions.Hall andKudlyak then exploremodelswhere there is feedback from high unemployment to the forces driving job creation. These mechanisms include higher recruiting costs early in the recovery, congestion in recruitment, externalities from recruitment selection, lower matching efficiency, impaired profitability of new matches, and persistently higher separation rates. These models imply that the recovery of aggregate unemployment is slower than the rate at which individual unemployed workers find new jobs. The paper tackles an interesting and eternal topic. Understanding how the labormarket recovers from recessionary shocks and howfirms recruit and search for workers helps us in shaping policy response to recessionary shocks. This comment reviews and interprets Hall and Kudlyak’s findings and suggests new directions of research.
Species Synonymies in the Deep-Sea Wood-Boring Bivalve Genus Xyloredo (Mollusca: Xylophagaidae)

ABSTRACT Sequences of specimens of the xylophagaid genus Xyloredo revealed minimal molecular divergence among ten specimens from the North and South Atlantic and the northeast and southwest Pacific Oceans. Although genetically identical, the valves of two New Zealand specimens differ dramatically, likely due to their three-fold size difference. Comparable size differences among the type series of X. nooi, X. naceli and X. ingolfia and their disjunct distributions may have contributed to their recognition as distinct species; the species are synonymized here as Xyloredo nooi. The flattened umbonal-ventral ridge, the fold inside the posterior shell, the two elongate calcified strips of the mesoplax embedded in a periostracal anterior adductor cover and a two-parted siphon with the simple, separate openings are unique to members of Xyloredo. Molecular sequencing of the Japanese X. teramachii is needed to test if it is distinct.
Northeastern Pacific Octopus Beak Shape for Species-Level Detection

ABSTRACT Cephalopods have upper and lower chitinous beaks, and their shape can be used to identify species. However, the morphological attributes of beaks are commonly obtained from sources that contain little information on shape, compromising the determination of taxa. Thus, in this study, we used geometric morphometrics to analyze inter-specific differences in beak shape of six octopus species from the northeastern Pacific. We found evidence of species-level discrimination according to upper and lower beak shape. In addition, we provided a detailed description of these chitinous structures for each species, and we developed a key to identify the species based on upper and lower beak shape. The inter-specific morphological variation of beaks of the octopuses evaluated in our study could be the result of adaptive processes related to habitat and feeding habits. The information generated in our study can be used for identification of six octopus species from the northeastern Pacific based on upper and lower beak shape.
