Numerical Study on Similarity of Plume's Infrared Radiation from Reduced Scaling Solid Rocket

Similarity of plume radiation between reduced scaling solid rocket models and full scale ones in ground conditions has been taken for investigation. Flow and radiation of plume from solid rockets with scaling ratio from 0.1 to 1 have been computed. The radiative transfer equation (RTE) is solved by the finite volume method (FVM) in infrared band 2~6 μm. The spectral characteristics of plume gases have been calculated with the weighted-sum-of-gray-gas (WSGG) model, and those of the Al2O3 particles have been solved by the Mie scattering model. Our research shows that, with the decreasing scaling ratio of the rocket engine, the radiation intensity of the plume decreases with 1.5~2.5 power of the scaling ratio. The infrared radiation of the plume gases shows a strong spectral dependency, while that of the Al2O3 particles shows grey property. Spectral radiation intensity of the high temperature core of the solid rocket plume increases greatly in the peak absorption spectrum of plume gases. Al2O3 particle is the major radiation composition in the rocket plume, whose scattering coefficient is much larger than its absorption coefficient. There is good similarity between spectral variations of plumes from different scaling solid rockets. The directional plume radiation rises with the increasing azimuth angle.
SELF-CONTROL AND THE THEORY OF CONSUMPTION

To study the behavior of agents who are susceptible to temptation in infinite horizon consumption problems under uncertainty, we define and characterize dynamic self-control (DSC) preferences. DSC preferences are recursive and separable. In economies with DSC agents, equilibria exist but may be inefficient; in such equilibria, steady state consumption is independent of initial endowments and increases in self-control. Increasing the preference for commitment while keeping self-control constant increases the equity premium. Removing nonbinding constraints changes equilibrium allocations and prices. Debt contracts can be sustained even if the only feasible punishment for default is the termination of the contract.
The development of murine cerebral malaria does not require nitric oxide production

Nitric oxide (NO) production has been suggested to be required for the development of cerebral malaria. However, the importance of this molecule for the appearance of this pathology is debated. To assess whether murine cerebral malaria is NO dependent, we investigated the course of blood-stage Plasmodium berghei ANKA (PbA) infections in inducible nitric oxide synthase (iNOS)-deficient mice. Parasitaemia, haematological alterations, survival and development of cerebral malaria were not affected by the lack of iNOS. To exclude a role of NO produced by other NOS, controls included NO suppression by oral administration of aminoguanidine (AG), a NOS inhibitor. As in iNOS-deficient mice, no difference in the parasitaemia course, survival and haematological values was observed after AG treatment. Our results indicate that NO production is not a crucial factor for the development of murine cerebral malaria.
Effect of mild hypothermia on nicorandil-induced vasodilation of pial arterioles in cats

Objective Nicorandil is characterized as hybrid between nitrates and potassium channel activators. Recent evidence suggested that mild hypothermia may alter cerebral vasodilation induced by a nitrate agent and potassium channel opener. However, the effect of mild hypothermia on nicorandil-induced vasodilation is not known. The present study was conducted to investigate whether mild hypothermia could alter nicorandil-induced cerebral vasodilation. In addition, the effects of mild hypothermia on cerebral vasodilation induced by nitroglycerin, a nitrate agent, and cromakalim, a selective adenosine 5′-triphosphate-sensitive potassium channel opener, were assessed in the same model. Design Prospective, randomized, experimental study with repeated measures. Setting Investigational animal laboratory. Subjects Twenty-four cats. Interventions Animals were anesthetized with pentobarbital. The cranial window technique, combined with microscopic video recording, was used to measure small (50–100 &mgr;m) and large (100–200 &mgr;m) pial arteriolar diameter in an experiment. Animals were assigned randomly to either a normothermic (37°C) or a hypothermic (33°C) group. Nicorandil, nitroglycerin, or cromakalim at concentrations of 10−8, 10−6, or 10−4 mol/L was applied topically in the cranial window, and the diameter of pial arterioles was measured. Measurements and Main Results Topical administration of nicorandil, nitroglycerin, and cromakalim significantly dilated both small and large pial arterioles in a dose-dependent manner during normothermia. Nicorandil-induced vasodilation of either large or small pial arterioles was not affected by hypothermia. However, hypothermia significantly attenuated nitroglycerine-induced vasodilation in both large and small pial arterioles and enhanced cromakalim-induced vasodilation in both large and small pial arterioles. Conclusions Nicorandil-induced vasodilation of cerebral pial arterioles was not affected by mild hypothermia. By contrast, mild hypothermia significantly attenuated nitroglycerin-induced vasodilation and enhanced cromakalim-induced vasodilation.
Impulse noise removal by using one-dimensional switching median filter applied along space-filling curve reflecting structural context of image

A switching median filter (SMF) is effective for impulse noise removal while still preserving edges in an input image. This filter firstly detects pixels corrupted by impulse noise and then filters only the noise-corrupted pixels. However the noise detection process does not always work perfectly. Particularly, pixels constituting thin lines in an input image tend to be incorrectly detected as noise-corrupted pixels, and such pixels are filtered despite the needlessness of the filtering. As the result of the filtering, the image might be over-smoothed and be deteriorated throughout the entire image. To cope with this problem, we propose a new impulse noise removal method based on a one-dimensional SMF and a space-filling curve which reflects structural contexts of an input image. The effectiveness of the proposed method is verified by some experiments.
An Operational System for Estimating Road Traffic Information from Aerial Images

Given that ground stationary infrastructures for traffic monitoring are barely able to handle everyday traffic volumes, there is a risk that they could fail altogether in situations arising from mass events or disasters. In this work, we present an alternative approach for traffic monitoring during disaster and mass events, which is based on an airborne optical sensor system. With this system, optical image sequences are automatically examined on board an aircraft to estimate road traffic information, such as vehicle positions, velocities and driving directions. The traffic information, estimated in real time on board, is immediately downlinked to a ground station. The airborne sensor system consists of a three-head camera system, a real-time-capable GPS/INS unit, five industrial PCs and a downlink unit. The processing chain for automatic extraction of traffic information contains modules for the synchronization of image and navigation data streams, orthorectification and vehicle detection and tracking modules. The vehicle detector is based on a combination of AdaBoost and support vector machine classifiers. Vehicle tracking relies on shape-based matching operators. The processing chain is evaluated on a large number of image sequences recorded during several campaigns, and the data quality is compared to that obtained from induction loops. In summary, we can conclude that the achieved overall quality of the traffic data extracted by the airborne system is in the range of 68% and 81%. Thus, it is comparable to data obtained from stationary ground sensor networks.
Assessment of Genetic Variations within Populations of Sika Deer in Japan by Analysis of Randomly Amplified Polymorphic DNA (RAPD)

Abstract Random amplified polymorphic DNA (RAPD) was exploited as a genetic marker to assess the level of genetic variation in populations of Sika deer, Cervus nippon, in Japan. DNA samples were collected from three local populations in Japan, namely, Kinkazan, Goyozan and Ashoro populations. Four arbitrary primers, when used individually, amplified an average of five RAPD fragments in the polymerase chain reaction (PCR). The number of polymorphic bands was scored to calculate band-sharing coefficients within populations. Average band-sharing coefficients revealed a higher degree of homogeneity in the Kinkazan population. Samples collected from larger populations, namely, Ashoro and Goyozan, revealed greater polymorphism than samples from the Kinkazan deer. Our data suggest that RAPD is useful as a marker for detecting genetic variations in populations of Sika deer with reduced levels of genetic diversity.
Kissing Molars: Report of a Case and Review of the Literature

Kissing molars are unusual impacted teeth which are in close contact with each other from their occlusal surfaces in one follicular space with positioning of roots in opposite directions. This report represented a review of literature and reported a case with kissing molars of lower third and fourth molars. The impacted teeth may lead to various complications which affect the life quality of a patient. A physician should know enough information about kissing molars and its possible risks to decide will the teeth be extracted or followed.
The extracellular regions of PSMA and the transferrin receptor contain an aminopeptidase domain: Implications for drug design

The Aeromonas proteolytica aminopeptidase (AMP), Pseudomonas sp. (RS‐16) carboxypeptidase G2 (CPG2), and Streptomyces griseus aminopeptidase (SGAP) are zinc dependent proteolytic enzymes with cocatalytic zinc ion centers and a conserved aminopeptidase fold. A BLAST search with the sequence of the solved AMP structure indicated that a similar domain could be found in prostate‐specific membrane antigen (PSMA) and the transferrin receptor (TfR). When the PSMA or TfR sequence was input into the THREADER program, the top structural matches were SGAP and AMP confirming that these are structurally conserved domains. Optimal sequence alignment of PSMA and TfR using the known three‐dimensional structures of AMP, CPG2, and SGAP shows that the critical amino acids involved in forming the catalytic pocket are conserved in PSMA but absent in the TfR. The specificity pocket in AMP is formed from four aromatic side chains and the equivalent region in CPG2/PSMA has a changed sequence pattern. Since CPG2 and PSMA are folate hydrolases, the changed specificity pocket leaves space to accommodate the large pteroate moiety of folic acid. In contrast, no enzyme function has been ascribed to the TfR.
Using Transcriptomics To Improve Butanol Tolerance of Synechocystis sp. Strain PCC 6803

ABSTRACT Cyanobacteria are emerging as promising hosts for production of advanced biofuels such as n-butanol and alkanes. However, cyanobacteria suffer from the same product inhibition problems as those that plague other microbial biofuel hosts. High concentrations of butanol severely reduce growth, and even small amounts can negatively affect metabolic processes. An understanding of how cyanobacteria are affected by their biofuel product can enable identification of engineering strategies for improving their tolerance. Here we used transcriptome sequencing (RNA-Seq) to assess the transcriptome response of Synechocystis sp. strain PCC 6803 to two concentrations of exogenous n-butanol. Approximately 80 transcripts were differentially expressed at 40 mg/liter butanol, and 280 transcripts were different at 1 g/liter butanol. Our results suggest a compromised cell membrane, impaired photosynthetic electron transport, and reduced biosynthesis. Accumulation of intracellular reactive oxygen species (ROS) scaled with butanol concentration. Using the physiology and transcriptomics data, we selected several genes for overexpression in an attempt to improve butanol tolerance. We found that overexpression of several proteins, notably, the small heat shock protein HspA, improved tolerance to butanol. Transcriptomics-guided engineering created more solvent-tolerant cyanobacteria strains that could be the foundation for a more productive biofuel host.

Virus-like particles in sera of patients with infectious and serum hepatitis.

In a prospective study of patients with serum hepatitis, 46 (74%) of 62 had Australia antigen in their serum. This high frequency of detectable antigen was probably due to sampling at weekly intervals during the acute phase of the disease. Antigen became detectable 35 to 120 days after exposure to contaminated blood products and persisted for one week to three months in 42 patients, and for more than ten months in 4 patients. Two of 128 healthy chimpanzees and one of 14 healthy gibbons also had the antigen. Antigens found in sera of patients with infectious or serum hepatitis and in ape sera were immunologically identical. Electron microscopy revealed morphologically similar virus-like particles both in sera from patients with hepatitis and from healthy apes. Australia antigen appears to be hepatitis virus itself, and a single virus group may be responsible for both infectious and serum hepatitis.
Common Nasal Anomalies and Its Implications on Intubation in Head and Neck Surgeries

Nasotracheal intubation used to be the preferred route for prolonged intubation in critical care units. Nasotracheal intubation may sometimes cause nasal trauma. The study included one hundred and nine (109) adult patients, were scheduled for elective head and neck surgeries with general anaesthesia, requiring nasotracheal intubation. All the patients compiled the criteria of American Society of Anesthesiologists (ASA) physical status I and II were included in this study. The incidence of complicated laryngoscopy was assumed as 8%, confidence levels at 99% and an error of 3%, the total sample size were One hundred and three (103) patients. Observation, recorded bleeding 63.11% (65-patients) of the time with the literature stating epistaxis rates from 17-77%. The study found there was a significant relationship of soft tissue profile and number of intubation attempts. In this study a concave profile was more likely to have multiple attempts, there was a significant relationship between moderate and severe bleeding and number of intubation attempts and in 04.85% (05-patients) of those patients with severe bleeding there were multiple intubation attempts. Thyromental distance and Mallampati score did not seem to have a significant relationship with either the number of intubation attempts or severity of bleeding. This may demonstrate that multiple attempts led to an increase in bleeding due to increased trauma or that bleeding from the nose into the oropharnyx and hypo-pharynx contributed to a difficult view of the larynx for passing the tube between the cords. The clinical relevance from this study to create an algorithm or define a set of factors to alert anesthetists to aware of knowledge about the common nasal anomalies for the difficult nasotracheal (NT) intubation.
Temperature characteristics of polysilicon piezoresistive nanofilm depending on film structure

The influence of film structure on temperature characteristics of polysilicon nanofilms (PSNFs) was reported in this paper. Samples were deposited by LPCVD with different film thickness and deposition temperature. The microstructure of films was characterized by SEM, TEM and XRD. By measuring the resistivity and the gauge factor of samples at different temperatures, temperature coefficients of the resistance and the gauge factor (TCR and TCGF) were investigated. Based on the analysis of tunneling piezoresistive effect, the results indicated that PSNFs of ultrahigh doping concentration (around 3times1020 cm-3) have better piezoresistive temperature characteristics than single crystal silicon. By controlling the process parameters like deposition temperature and film thickness, film structure was optimized to obtain a very low resistance temperature coefficient (about plusmn10-4/degC). Moreover TCGF was negative and almost not affected by deposition temperature and film thickness. These conclusions are useful for temperature compensation of polysilicon pressure sensors.
Molecular studies of an X;Y translocation chromosome in a woman with deletion of the pseudoautosomal region but normal height

A translocation chromosome in a woman with the karyotype 46,X,der(X)t(X;Y)(p22.3; q11.2) was investigated by FISH and STS analysis with molecular probes derived from the sex chromosomes. Due to the partial deletion of the short arm pseudoautosomal region (PARI) from DXYS14 to DXYS147 in the translocation chromosome, the proband is hemizygous for the gene responsible for growth control (SS) located in this region, yet does not show growth retardation. Molecular analysis of the Yq arm of the translocation chromosome revealed the presence of markers DYS273 to DYS246 harboring the hypothesized growth control gene critical region (GCY) on Yq, thereby placing the deletion breakpoint between markers DYS11 and DYS273. These results suggest that the Y‐specific growth gene GCY on Yq compensates for the missing growth gene SS on Xp22.3.
Development in electronically-supported groups: a preliminary longitudinal study of distributed and face-to-face meetings

This longitudinal pilot study compared the developmental patterns of groups in three different electronically supported meeting modes: face-to-face, dispersed-synchronous and dispersed-asynchronous. Comparisons along several behavioral and socio-technical dimensions which influence the group development process indicate that face-to-face groups experience more effective leadership and coordination competence over time compared to the distributed groups. However, dispersed groups did not differ from their face-to-face counterparts in cohesiveness and equality of participation. Moreover, groups in all three modes performed the task equally well. These results suggest that electronically distributed work groups/spl minus/with adequate time and training/spl minus/can become cohesive and perform effectively. <<ETX>>
Energy Efficient Source Location Privacy Protecting Scheme in Wireless Sensor Networks Using Ant Colony Optimization

Wireless sensor networks consist of various sensors with limited power, which collect different useful and privately relevant information. We pay attention to some issues related to sensor's location privacy. Ant colony optimization provides a natural and intrinsic way of exploration of search space for preserving sensor's location privacy. In this paper, we focus on protecting the sensor's location by introducing suitable modifications to sensor routing to make it difficult for an eavesdropper to find the original location. And we propose an energy efficient preserving sensor's location privacy based on ant colony optimization scheme, which is a flexible routing strategy to protect the sensor's location. Simulation results show that our strategy can efficiently reduce the chance of packets being detected and prolong the network lifetime. And the adversary can find it difficult to find the exact location of the source node.
PTP1B deficiency enhances liver growth during suckling by increasing the expression of insulin‐like growth factor‐I

Protein tyrosine phosphatase 1B (PTP1B) is a negative regulator of insulin and tyrosine kinase growth factor signaling. We have recently demonstrated that PTP1B deficiency increases GLUT2/insulin receptor (IR) A complexes and glucose uptake in suckling, but not adult, primary hepatocytes. Herein we have investigated intrahepatic glucose utilization in 3–5 days old wild‐type and PTP1B−/− mice. PTP1B deficiency decreased glycogen, lactate, and pyruvate content in the livers from suckling mice. Conversely, the activity of glucose 6‐phosphate dehydrogenase (G6PD), the rate limiting enzyme of the pentose phosphate cycle (PPC) which provides substrates for DNA synthesis, was enhanced in the liver of PTP1B−/− animals. Liver weight, liver‐to‐body mass ratio, DNA content, and PCNA expression were increased in PTP1B−/− suckling mice compared to the wild‐type controls. At the molecular level, STAT 5B phosphorylation, IGF‐I mRNA, and protein levels as well as IGF‐IR tyrosine phosphorylation were increased in the livers of PTP1B‐deficient neonates. Unexpectedly, hepatic and serum triglycerides (TG) were increased by PTP1B deficiency, although the expression of lipogenic enzymes remained as in the wild‐type controls. However, the analysis of milk composition revealed higher TG content in lactating females lacking PTP1B. The effects of PTP1B deficiency on G6PD activity, STAT 5B/IGF‐I/IGF‐IR axis, PCNA expression and liver growth during suckling were maintained by transferring PTP1B−/− embryos (PTP1B−/−T) to a wild‐type female. Conversely, PTP1B−/−T mice did not show hepatic fat accumulation. In conclusion, the present study suggests that PTP1B plays a unique role in the control of the physiological liver development after birth. J. Cell.

Suitable models for face geometry normalization in facial expression recognition

Abstract. Recently, facial expression recognition has attracted much attention in machine vision research because of its various applications. Accordingly, many facial expression recognition systems have been proposed. However, the majority of existing systems suffer from a critical problem: geometric variability. It directly affects the performance of geometric feature-based facial expression recognition approaches. Furthermore, it is a crucial challenge in appearance feature-based techniques. This variability appears in both neutral faces and facial expressions. Appropriate face geometry normalization can improve the accuracy of each facial expression recognition system. Therefore, this paper proposes different geometric models or shapes for normalization. Face geometry normalization removes geometric variability of facial images and consequently, appearance feature extraction methods can be accurately utilized to represent facial images. Thus, some expression-based geometric models are proposed for facial image normalization. Next, local binary patterns and local phase quantization are used for appearance feature extraction. A combination of an effective geometric normalization with accurate appearance representations results in more than a 4% accuracy improvement compared to several state-of-the-arts in facial expression recognition. Moreover, utilizing the model of facial expressions which have larger mouth and eye region sizes gives higher accuracy due to the importance of these regions in facial expression.
