The population and evolutionary dynamics of bacteriophage: Why be temperate revisited

Bacteriophages are deemed either lytic (virulent) or temperate, respectively depending on whether their genomes are transmitted solely horizontally, or both horizontally and vertically. To elucidate the ecological and evolutionary conditions under which natural selection will favor the evolution and maintenance of lytic or temperate modes of phage replication and transmission, we use a comprehensive mathematical model of the dynamics of temperate and virulent phage in populations of bacteria sensitive and resistant to these viruses. For our numerical analysis of the properties of this model, we use parameters estimated with the temperate bacteriophage Lambda, λ, it’s clear and virulent mutants, and E. coli sensitive and resistant - refractory to these phages. Using batch and serial transfer population dynamic and reconstruction experiments, we test the hypotheses generated from this theoretical analysis. Based on the results of this jointly theoretical and experimental study, we postulate the conditions under which natural selection will favor the evolution and maintenance of lytic and temperate modes of phage replication and transmission. A compelling and novel prediction this in silico, in vitro, and in plastico study makes is lysogenic bacteria from natural populations will be resistant-refractory to the phage for which they are lysogenic as well as lytic phage sharing the same receptors as these temperate viruses.
Vehicle Detection With Automotive Radar Using Deep Learning on Range-Azimuth-Doppler Tensors

Radar has been a key enabler of advanced driver assistance systems in automotive for over two decades. Being an inexpensive, all-weather and long-range sensor that simultaneously provides velocity measurements, radar is expected to be indispensable to the future of autonomous driving. Traditional radar signal processing techniques often cannot distinguish reflections from objects of interest from clutter and are generally limited to detecting peaks in the received signal. These peak detection methods effectively collapse the image-like radar signal into a sparse point cloud. In this paper, we demonstrate a deep-learning-based vehicle detection solution which operates on the image-like tensor instead of the point cloud resulted by peak detection.To the best of our knowledge, we are the first to implement such a system.
Assessing the geochemical variability of oil shale in the Attarat Um Ghudran deposit, Jordan

The Cretaceous to Palaeogene oil shale (OS) of Jordan is predominantly calcareous mudstone with intervals of mostly siliceous minerals, quartz and cristobalite–tridymite. Oil shale is rich in organic sulphur and trace elements. According to preliminary micropalaeontological data, the OS succession of the studied area, the south-central part of the Attarat Um Ghudran (AUG) deposit in central Jordan, is of Maastrichtian age. A representative collection of 392 samples from 9 drill cores reliably characterizes the sequence of the OS seam, on average 70 m thick. The composition of AUG OS varies significantly. The major compounds CaO and SiO2 range within 3–70 wt% and 10–50 wt%, respectively, and also the contents of organic matter, MgO, P2O5, Al2O3 and S change. The concentrations of metals (especially Zn, V, Cr, Ni and Mo) change many dozens of times in the cross section. The aim of our statistical analysis was to determine the most significant OS types and their positions in the OS sequence. Two multivariate statistical analysis methods, principal components analysis (PCA) and hierarchical clustering of PCA groups, gave an interpretable result. Four principal components account for 88.6% of data variability. Variation in six main chemical components or groups of components is reflected in parameters of the four principal components. The component PC1 accounts for 47% of the data variance, expressing the highest correlation with organic matter, S, Cr, Cu, Ni, Zn, Mo, and PC2 accounts for 22.82% of the data variability, being strongly correlated with TiO2, Al2O3, Fe2O3, SiO2 and K2O and negatively correlated with CaO. The next two significant component groups express covariance with CaO and MgO. The applied statistical analysis proves to be a powerful tool for the interpretation of the chemically variable structure of the OS unit when using a representative enough sample collection. In the complex study of the OS unit, variation in the chemical composition is of interest, especially in the context of genetic and mining aspects.
Synthesis and characterization of magnesium borate minerals of admontite and mcallisterite obtained via ultrasonic mixing of magnesium oxide and various sources of boron: a novel method

Magnesium borates can be used as detergent compounds or hydrocarbon catalyzers and in the ceramics industry for superconductor material manufacture owing to their high elastic coecient and resistance to corrosion at high temperatures. In the present study, the synthesis of magnesium borate was facilitated via a novel ultrasonic method of mixing and the identication and characterization of the material were carried out via X-Ray diraction (XRD), Fourier transform infrared (FT-IR), and Raman spectroscopies, and the B2O3 content was determined through titration. The surface morphology was investigated using scanning electron microscopy (SEM). The results of the XRD analysis identied the synthesized borate compounds as admontite (MgO(B 2O3)3.7(H2O)), with powder diraction le (pdf) no 01-076-0540, and mcallisterite (Mg2(B6O7(OH)6)2.9(H2O)), with pdf no 01-070-1902. The FT-IR and Raman spectra of the obtained samples were similar, with characteristic magnesium borate bands observed in both the infrared and visible regions. The results of the B2O3 content analysis were in compliance with the literature. The investigation of the SEM images indicated that nanoscale minerals with a reaction eciency ranging between 69% and 82% were
Turkish Journal of Zoology

This study examined the atrioventricular conducting system in 4 adult male hedgehogs (Hemiechinus auritus). The histological structure of these components was studied using routine histological methods. The AVN was located at the lower and anterior part of the interatrial septum, near the root of the aorta. It was almost oval and consisted of twisted cells. Internodal pathways in the hedgehog heart were not observed, but there were numerous purkinje-like fibers within the myocardium of the atrium. The AVB was a continuation of the AVN, as a compact structure, extended obliquely through the fibrous ring toward the apex of the interventricular septum, and was composed of many purkinje cells.
Evaluation of Total Phenolic Content, Antioxidant Activities and Sugar Content of Fresh Mixed Fruit and Vegetables Juices

The notion of fruit and vegetables (FV) in preventing chronic diseases has long been discerned. To meet the recommended FV intake, FV juices have emerged as a convenient and healthy choice. Mixed fruit and vegetable juices (MFVJ) cater the blend of desirable flavor and taste of consumers. This study was carried out to determine the total phenolic content (TPC), antioxidant activities and sugar content of selected MFVJ. Folin-Ciocalteu assay was employed to quantify TPC, whereas DPPH and FRAP assays were used to evaluate the antioxidant activities of MFVJ. The sugar content was determined using phenol-sulfuric acid method. MFVJ extracted from bitter gourd, green apple and orange (BGO) had the highest TPC content (76.4 ± 4.2 mg GAE/100 ml). Celery and green apple (CG) juice showed the highest DPPH value (522.3 ± 7.6 mg TE/100 ml) whereas carrot and starfruit (AS) juice have the highest FRAP value (419.6 ± 21.6 mg TE/100 ml). The sugar content of MFVJ was within the range of 5.7-13.3 g/100 ml. MFVJ can be considered as healthy beverages with considerable amounts of phenolic compounds and low sugar content. This study provides some useful reference for consumers who consume juices with combinations of FV. Future studies need to discover more combinations of FV juices, providing more data pertaining to MFVJ. Identification of individual phenolic compounds should also be part of future research using various instrumental analyses. DOI : http://dx.doi. org. /10.17576/JSKM-2017-1502-07
Effects of International Taxation on Firm Dynamics and Capital Structure

I develop and calibrate an industry equilibrium model with heterogeneous multinational firms to study the impact of a potential policy change from the current U.S. worldwide taxation system to a territorial system on firm investment, capital structure, payout policy and tax revenues. Firms in the model make both intensive and extensive margin decisions in terms of overseas investment. They optimally choose dividend payments to shareholders, holdings of riskless debt securities and earnings repatriations from the subsidiary to the parent in each period. To estimate the impact of the policy change, I solve the model under both worldwide and territorial systems and compare the stationary equilibria. The results show that the policy change causes both domestic and overseas production by U.S. firms to rise. In addition, firms borrow more and pay larger dividends to shareholders. These effects on firm variables are coupled with a rise in U.S. Government tax collections. ∗I thank Oliver Levine and my advisor, Dean Corbae, for some valuable discussions that helped me to develop this project and to get it off the ground.

Shellac Thin Films Obtained by Matrix-Assisted Pulsed Laser Evaporation (MAPLE)

We report on the fabrication of shellac thin films on silicon substrates by matrix-assisted pulsed laser evaporation (MAPLE) using methanol as matrix. Very adherent, dense, and smooth films were obtained by MAPLE with optimized deposition parameters, such as laser wavelength and laser fluence. Films with a root mean square (RMS) roughness of 11 nm measured on 40 × 40 µm2 were obtained for a 2000-nm-thick shellac film deposited with 0.6 J/cm2 fluence at a laser wavelength of 266 nm. The MAPLE films were tested in simulated gastric fluid in order to assess their capabilities as an enteric coating. The chemical, morphological, and optical properties of shellac samples were investigated by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and atomic force microscopy (AFM).
NDT_A_213212 2345..2352

Department of Neurology, The First Affiliated Hospital of Jinzhou Medical University, Jinzhou 121001, Liaoning, People’s Republic of China Background: Cerebral ischemia/reperfusion injury (I/R injury) is an important pathological process for nervous system. The I/R injury usually causes cerebral hypoxia, infarct or stroke. This study aimed to evaluate effects of troxerutin and cerebroprotein hydrolysate injection (TC) on I/R injury in rat models. Methods: Middle-cerebral artery occlusion/reperfusion (MCAO/R) rat models were established. Rats were divided into normal control (NC), MCAO/R rat model (injecting saline) and MCAO/R rats administrating with TC group (injecting with TC at concentration of 2 mL/100 g body weight). Neurological scores were evaluated with Garcia scale. Magnetic resonance imaging (MRI) was employed to observe infarct area, contralateral area and apparent diffusion coefficient (ADC) values. Cerebral infarct size was examined and visualized by staining with 2,3,5-triphenyltetrazolium chloride (TTC). Western blotting assay was used to determine caspase-1, caspase-3 and caspase-8 expression. Results: The infarct size of mice in MCAO/R+TC group was smaller significantly compared to that in MCAO/R group (p<0.05). The infarct/contralateral area ratio of T2 and T2 Flair signals in MCAO/R+TC group were lower significantly compared to that in MCAO/R group (p<0.05). ADC values in MCAO/R+TC group were significantly enhanced compared to that in MCAO/R group (p<0.05). The troxerutin and cerebroprotein treatment significantly increased neurological scores compared to that in MCAO/R group (p<0.05). Troxerutin and cerebroprotein treatment significantly decreased expression of caspase-1, caspase-3, caspase-8 compared to that in MCAO/R group (p<0.05). Conclusion: Troxerutin and cerebroprotein administration alleviated cerebral I/R injury by down-regulating caspase molecules.
AS CORRELATE OF ENTREPRENEURSHIP DEVELOPMENT

Owing to the overtly increasing level of religiosity without a corresponding increase in spirituality, the low entrepreneurial intentionality among jobless youths, the high rate of unemployment and poverty, and the uncertainties in the Nigerian business environment which have given rise to an unprecedented need to fasttrack entrepreneurship development, this study was designed to investigate the influence of the dimensions of spirituality on entrepreneurship development. The study identified vision, hope/faith, altruistic love, meaning/calling and membership as the dimensions of spirituality. The data generated were analysed using multiple regression analysis. It was found that vision, meaning/calling and altruistic love are the significant predictors of entrepreneurship development. The study concludes that: vision will inspire entrepreneurial intentions and motivate would-be entrepreneurs to seek to actualize their vision through entrepreneurial networking support; meaning/calling will instigate the acquisition of entrepreneurial capabilities from entrepreneurial network providers; and altruistic love will enhance their integration into the network and the eventual cordial work-support relationship that will assure entrepreneurial success. The study recommends a reinvention of entrepreneurship development centres/agencies and a review of entrepreneurship development curriculum so as to ensure the internalization of spirituality values by budding entrepreneurs.
Performance Evaluation of Visual Object Detection and Tracking Algorithms Used in Remote Photoplethysmography

While most existing remote photoplethysmography (rPPG) approaches employ off-the-shelf visual object detection and tracking algorithms, these algorithms may not be well suited for rPPG problem. The detection and tracking algorithms are designed to be robust to fast deformations, non-distinctive color, fast translations, etc. while rPPG cares about background intervention, region consistency, smoothness of the traces, etc. Hence, there is a gap between a good detection and tracking algorithm and the rPPG measurement accuracy. This paper aims at bridging this gap by evaluating the performance of popular detection and tracking algorithms widely used in rPPG methods. We establish a processing pipeline and choose four detection and tracking algorithms. Experiments are conducted on two publicly available datasets and one self-collected dataset. We find three key factors that affect the rPPG accuracy: 1) stability of the tracking trajectory, 2) content consistency, and 3) robustness to deformation and fast translation. This study highlights the need for developing novel detection and tracking algorithms dedicated to rPPG and gives some useful insights.
Regularity results for pluriclosed flow

In prior work the authors introduced a parabolic flow of pluriclosed metrics. Here we give improved regularity results for solutions to this equation. Furthermore, we exhibit this equation as the gradient flow of the lowest eigenvalue of a certain Schr\"odinger operator, and show the existence of an expanding entropy functional for this flow. Finally, we motivate a conjectural picture of the optimal regularity results for this flow, and discuss some of the consequences.
Supplementary value of two Lablab purpureus cultivars and concentrate mixture to natural grass hay basal diet based on feed intake, digestibility, growth performance and net return of Horro sheep

This study was undertaken with the aim to determine the supplementary value of Beresa-55 and Gebisa-17 cultivars and concentrate mixture to a basal diet of natural pasture hay based on growth performance, feed utilization, digestibility and net return of Horro sheep. A total of twenty five yearlings Horro sheep were stratified into five groups based on initial body weight in randomized complete block design and animals were assigned to the dietary treatments randomly: (T1) (Control): ad-lib natural grass + concentrate mixture at 2% BW, (T2): ad-lib natural grass + Gebisa-17cultivar at 1.5% BW, (T3): ad-lib natural grass + Gebisa-17 cultivar at 2% BW, (T4): ad-lib natural grass + Beresa-55 cultivar at 1.5% BW and (T5): ad-lib natural grass + Beresa-55 cultivar at 2% BW. Basal hay DM intake was relatively higher in T2 and T4, while total DM and CP intake was higher in T1 and T5. Similarly, significantly higher digestibility of DM, CP and organic matter (OM) was obtained in T1 and T5. Dietary treatments also significantly (P 0.01) weight gain and enhanced comparable growth performance than in the other treatments. However, partial budget analysis indicates that, T5 is more profitable and thus, can be used as a priority supplement in feeding of Horro sheep. Key words: Horro sheep, Lablab purpureus, weight gain, digestibility, feed intake.
Gamma Radiation Sensitivity of Different Stages of Saw-Toothed Grain Beetle Oryzaephilus Surinamensis L. (Coleoptera: Silvanidae)

The effect of gamma irradiation on different developmental stages of Oryzaephilus surinamensis L. , was investigated. Re- sults showed that a required dose to prevent larval emergence from irradiated 1-2-days-old eggs was 60 Gray (Gy), and 350 Gy was required to prevent adult emergence from 15-days-old larvae. Also the required dose of radiation to prevent adult emergence from irradiated 5-days-old pupa was 700 Gy. The dose of 200 Gy caused 100% mortality of irradiated adults 28 days after treatment. In addition, the effect of gamma rays was studied on the developmental stage period of each irradiated stage till adult emergence. The results revealed that there was a dose-dependent increase of the developmental periods. The growth index of adults was significantly decreased with increasing dose of radiation administered to eggs, larvae and pupae. It is recommended that doses between 600 and 700 Gy should be used to control population growth of O. surinamensis when targeting pupae and adults present in stored products.

Simulating maize phenology as a function of air temperature with a linear and a nonlinear model

The objective of this study was to adapt a nonlinear model (Wang and Engel - WE) for simulating the phenology of maize (Zea mays L.), and to evaluate this model and a linear one (thermal time), in order to predict developmental stages of a field-grown maize variety. A field experiment, during 2005/2006 and 2006/2007 was conducted in Santa Maria, RS, Brazil, in two growing seasons, with seven sowing dates each. Dates of emergence, silking, and physiological maturity of the maize variety BRS Missoes were recorded in six replications in each sowing date. Data collected in 2005/2006 growing season were used to estimate the coefficients of the two models, and data collected in the 2006/2007 growing season were used as independent data set for model evaluations. The nonlinear WE model accurately predicted the date of silking and physiological maturity, and had a lower root mean square error (RMSE) than the linear (thermal time) model. The overall RMSE for silking and physiological maturity was 2.7 and 4.8 days with WE model, and 5.6 and 8.3 days with thermal time model, respectively.

A KINETIC COMPARISON OF THE INSIDE SOCCER KICK BETWEEN HIGH PERFORMANCE PLAYER AND JUNIOR PLAYERS

Kinetic aspect of the inside soccer kick was investigated and comparison was made between those of a high performance player and junior players. One high performance player and five junior players volunteered to participate in this study. Their kicking motions were analyzed through three-dimensional cinematograpgic technique. Joints torques, generated at hip and knee joints, were computed by a three-link kinetic chain composed of thigh, shank, and foot. A marked difference was observed for the hip external rotation torque. All the junior players exhibited hip external rotation torque, and its magnitude was particularly dominant in the latter part of leg swing. Conversely, the magnitude of hip external rotation torque for the professional player was negligible. These results may help to explain differences in kicking techniques between the two levels of players.
