Opposition control of turbulent taylor-couette flow

Direct numerical simulations (DNS) of an opposition-controlled turbulent Taylor-Couette (TC) flow is performed. Opposition control is then applied. Significant drag reduction is achieved by opposition control and the skin friction drag is decreased up to 31% with the wall-normal control. Strong modifications of the turbulence statistics in the near-wall region are observed. The streamwise velocity fluctuation is greatly reduced and shows a more symmetric profile. The origin of the boundary layers seems to undergo a displacement toward the middle of the flow. Besides, the visualization of the coherent flow structures shows a significant reduction of their number when the control is applied. In a further step, the combination of wall-normal and spanwise control, as well as the influence of the gain on the input response are investigated. The efficiency of this control strategy is then compared with the opposition control.Copyright © 2011 by JSME

Detection of Rh antibodies using two low ionic diluents: Extension of the incubation time and the number of Rh antibodies detected Immunophenotypic characterisation of peripheral T lymphocytes in pulmonary Relationship between N-terminal pro-B type natriuretic peptide and extensive echocardiographic parameters in mild to moderate aortic stenosis Relative efficiency of polymerase chain reaction and enzyme-linked immunosorbant assay ABSTRACT Context: The N-terminal pro-B type natriuretic peptide levels (NT pro-BNP) are increased in cases of volume or pressure overload. Aims: To examine NT pro-BNP levels and enclose whether any relationship is present between the levels of NT pro-BNP and extensive echocardiographic parameters in asymptomatic patients with mild to moderate aortic stenosis (AS). Settings and Design: A cross-sectional study about the NT pro-BNP levels was conducted in 37 asymptomatic AS patients and compared with 40 controls. Methods: Patients <70 years old with mild to moderate AS with a peak transaortic gradient >20 mm Hg in transthoracic echocardiogram were included in our study. Extensive echocardiographic parameters and NT pro-BNP levels were obtained from these patients and these indices were compared with the control population selected from the patients who had similar clinical characteristics with the AS patients. Statistical Analysis: NT-proBNP values were found to be distribution free. Spearman correlation coefficient was used for correlation analysis. Mean values were compared by the Kruskal-Wallis test. Results: The NT pro-BNP levels were increased in patients with AS (median; interquartiles range: 686 [449-855] pg/mL vs. 140 [116-150] pg/mL, P < 0.001). Among patients with AS, when correlation analysis was performed mean transaortic gradient, aortic valve area index, myocardial performance index, E m /A m ratio, left-ventricular mass index (LVMI) and E/E m ratio had correlations (r=0.38, P = 0.026; r=-0.46, P =0.008; r=0.19, P =0,049; r=-0.22, P =0.04, r=0.49, P =0.003 and r=0.53, P <0.001 respectively) with plasma NT pro-BNP levels. The LVMI (r = 0.49, P = 0.003) and E/E m ratio (r = 0.53 P < 0.001) have the strongest correlations when compared to other parameters. Conclusion: Plasma NT pro-BNP levels are increased in even asymptomatic patients with AS and correlated with several echocardiographic parameters related to severity of AS and degree of diastolic dysfunction. As a result, NT pro-BNP levels may be used in the follow-up of asymptomatic patients having mild to moderate AS.
Effect of Processing Condition and Polishing Rate on Apparent Amylose Content of Some Sri Lankan Rice Varieties

Rice ( Oryza sativa ) is the staple food in Sri Lanka. Amylose content is the key determinant of cooking and eating qualities of rice. Therefore it is commonly used as an objective index for cooked rice texture. High amylose varieties tend to have low glycemic indices. This study investigated the apparent amylose content of raw and parboiled rice which were polished at 10% and 5% on weight basis in six Sri Lankan rice varieties. Determination of apparent amylose content was done according to AACC method 61-03. Five Bg varieties; 2 short grain (Bg 358, Bg 360), two medium grain (Bg 300, Bg 352) and one long grain (Bg 305) were used for the study together with the long grain rice variety At 405. The apparent amylose content of rice varieties Bg 300, Bg 305, Bg 352, Bg 358, Bg 360 and At 405 under 10% polished raw were 29.3±0.4%, 32.5±1.3%, 32.8±0.75%, 26.1±0.8%, 31.9±0.8% and 14.9±1.3%, respectively.

Developed Design for Humeral Head Replacement Using 3D Surface Mapping

Abstract Assessment of dimensional and geometrical data on the humeral head replacement (HHR) objects is essential for solving the relevant designing problems in the physics of reverse engineering (RE). In this work, 2D-assessment for human humerus was performed using the computed tomography (CT) technique within the RE plan, after which the 2D images of humeral objects were converted into 3D images. The conversion was successful and indicated a clear difference in the 2D and 3D estimates of sizes and geometry of the humerus. The authors have analyzed and confirmed experimentally the statistical information on the relevant anatomical objects. The results of finite-element simulation of the compressive stresses affecting the geometry of 3D surface mapping were analyzed using SolidWorks software. For developing the biomechanical design of an HHR object suitable biomaterials were selected, and different metal-based biomaterials are discussed as applied at various loads. New methodology is presented for the size estimation of humeral head - both anatomical and artificial - in 3D-shape. A detailed interpretation is given for the results of CT D-measurements.

Proposing a Quantum simulator for integer factorization1

— Many cryptographic algorithms depend on computational complexity assumptions. Notorious cases are the RSA algorithm for public key criptography or the DiffieHellman key exchange protocol, to publicly agree on a common secret key. Both algorithms are known to be broken by quantum computing as well as those that can be reduced to a discrete logarithm problem. These are key algorithms in our digital society and are at the basis of everyday tasks, specially those that rely on digital signatures. The RSA algorithm, in particular, is probably the most used algorithm and is its assumed security the one that guards most of the e-commerce nowadays. In this case, it is the time complexity of finding the prime factors of a large number, that grows worse than polinomially with the size of the number, the manin guardian of our cyberinfrastructure. The fact that a quantum computer can solve this problem in polynomial time using Shor’s algorithm is seen as a potentially major disruption and has prompted security agencies to advice the progressive deprecation of these algorithms[2]. However, the practical realization of quantum computers able to implement the Shor’s algorithm to factor numbers of the size used in the day to day use of RSA, is still years in the future. The typical implementations of Shor’s algorithms use the gate model of quantum computing, but another possibility would be to build the solutions in Hilbert space of a quantum simulator performing factorization, instead of going through the route of a gate-based, fully programmable, quantum computer. The key idea, following the pioneering suggestions of Feynman[4], is to translate factoring arithmetics into the physics of a device whose superposition of states mimics the problem i.e.: a factoring (analog) computer. The states of the simulator would be the solutions of some hermitian operator depending only on the number that we want to factorize. This is an ”analogue” computer in the sense that it is not like the Shor’s 1Parts of this contribution are under revision in Phys. Rev. Lett.
Title Capturing the Impact of Fuel Price on Jet Aircraft Operating Costs with Engineering and Econometric Models Permalink

Challenges in forecasting fleet development and deployment are in part due to fuel price uncertainty. To address this issue, a recent study developed an aircraft-specific Leontief technology operating cost model (LM) to compare aircraft costs under fuel price uncertainty. This model considers individual aircraft types to be Leontief technologies, such that the key drivers of cost must be used in fixed quantities. While asserted in the literature that models in this form can more accurately predict operating costs, the Leontief specification precludes a precise examination of how aircraft size will change due to economic forces. To this end, an econometric operating cost model (EM) is developed. The translog functional form is used to capture the effect of the key drivers of cost on jet operating costs and also allow for substitution between inputs. A comparison of the LM and EM shows that the Leontief technology assumption limits the LM to capturing operating costs in only a snapshot in time, while the EM captures the input substitution that occurs with factor price changes. The conclusion that the EM has strong predictive potential encourages a strengthening of the model towards capturing costs related to passenger preferences. This study takes a total logistics cost approach (TLC) and considers passenger value of frequency along with operating cost to be the total cost per operation. The cost-minimizing seat size is smaller and more reflective of existing conditions under TLC compared with operating cost alone, yet the difference diminishes as fuel price increases. This study highlights the predictive potential of econometric cost models and also the importance of considering passenger preferences in predicting future aircraft economics.

Actinokineospora guangxiensis sp . nov . , isolated from soil

A novel actinomycete, designated strain GK-6, was isolated from a soil sample from Nanning, Guangxi province, PR China. The strain grew at 20–40 8C, pH 6.0–11.0 and with 0–7.0 % NaCl. It formed well-developed aerial and vegetative mycelia. The aerial mycelium was white and the vegetative mycelium was yellow. The long branching aerial mycelia yielded rod-shaped arthrospores, the spores had smooth surfaces and were non-motile. Strain Gk-6 contained meso-diaminopimelic acid as the diagnostic diamino acid, the whole-cell sugars were galactose, glucose and arabinose. Major fatty acids were iso-C16 : 0, iso-C15 : 0 and C17 : 0. MK-9(H4) was the predominant menaquinone. The polar phospholipids were phosphatidylethanolamine, phosphatidylethanolamine-containing hydroxylated fatty acids, diphosphatidylglycerol, ninhydrinpositive glycophospholipid and an unknown phospholipid. The G+C content of the genomic DNA was 73.4 mol%. The 16S rRNA gene sequence analysis indicated that the organism was a member of the genus Actinokineospora and its closest relative among recognized species was Actinokineospora soli JCM 17695 (97.7 % sequence similarity). But the phenotypic characteristics of strain Gk-6 were significantly different from those of A. soli JCM 17695, and DNA–DNA hybridization showed low relatedness (22.6–28.3 %) between strain Gk-6 and JCM 17695. On the basis of the phenotypic and phylogenetic data, strain Gk-6 represents a novel species of the genus Actinokineospora, and the name Actinokineospora guangxiensis sp. nov. is proposed. The type strain is Gk-6 (5DSM 46779 5CGMCC 4.7154).
May gen. n. (Araneae: Sparassidae): A Unique Lineage from Southern Africa Supported by Morphological and Molecular Features

Abstract A new genus of huntsman spiders, May gen. n. is described from southern Africa, together with four new species: M. bruno sp. n. (♂, ♀; South Africa), M. ansie sp. n. (♂; Namibia), M. rudy sp. n. (♂; Namibia) and M. norm sp. n. (♀; Namibia). Diagnostic characters proposed include not only those for the genus but also for the so-called African clade. Unique within the entire family are the reduction of the gnathocoxal serrula and the prolaterad embolus. Special claw tuft setae and metatarsi I to III with three prolateral and retrolateral spines, respectively, occur in the entire African clade. A proximal cymbial shoulder in the male palp, the fused lateral lobes of the epigyne and the prolateral proximal spine of leg I shifted to a median position is characteristic for May gen. n. A family-wide analysis of genetic distance in the nuclear 28SrDNA gene (28s), including M. bruno sp. n. , supports its isolated placement and thus the genus hypothesis.
Exact algorithms for MAX-2SAT and MAX-3SAT via multidimensional matrix multiplication

In this thesis it is showed how an O(n4− ) algorithm for the cube multiplication problem (that is defined in the thesis) would imply a faster than naive O∗(2n(1− 4 )) algorithm for the max-3sat problem; this algorithm for max-3sat is a generalization of the algorithm for the max-2sat problem which was proposed by Ryan Williams; and cube multiplication, in turn, is defined as a generalization of the matrix multiplication problem for three-dimensional arrays. Approaches to find a faster than naive algorithm for cube multiplication are considered. Though no such algorithm was found using these approaches, it is showed how a variant of the Strassen algorithm for matrix multiplication could be found using the same approaches. Implementations of these approaches using computer programming and results of computational experiments are discussed.
Effect of Restricted Suckling or Temporal Weaning on Some Physiological and Behavioural Stress Parameters in Zebu Cattle (Bos indicus)

This study investigated the effects of restricted suckling (RS) on some physiological and behavioural stress parameters compared to temporal weaning (TW). Twenty Brahman (Bos indicus) cow-calf pairs were assigned to one of two groups: Calves in the RS group were limited to suckle their dams once daily for 30 min during days 30 to 33, while calves in the TW group were removed from their dams during days 59 to 62 postpartum. Heart and respiratory rates, serum cortisol concentration and body temperature were registered in cows and calves. In addition, the number of steps was also registered in calves. All parameters were recorded 24, 48 and 72 h after the beginning of the two treatments, respectively. In TW calves, higher (p<0.05) cortisol concentration and number of steps were recorded in the 1 st samples and 1 st and 2 nd observations, respectively. No difference was found in body temperature between treatments. However, respiration and heart rates differed in the 1 st and 2 nd observations, respectively. In general, a significant decrease (p<0.05) in these three parameters was observed over time. In cows, no differences were found in cortisol concentration or body temperature between treatments or with time. Heart and respiratory rates were lower (p<0.05) in the TW treatment only 24 h after beginning of treatment. It was concluded that (a) RS resulted in less behavioural and physiological indices of distress compared to TW in calves, although in general, differences were found only in some variables, mainly during the 1 st day following start of the treatment, and there in a chance of age effects. (b) Cows were less affected than their young, regardless of the treatment applied. (Asian-Aust. J. Anim. Sci. 2005. Vol 18, No. 8 : 1176-1181)

The effect of selenium on immunogenicity of influenza vaccine in the elderly: A case-control double-blinded clinical trial

Introduction: Influenza can cause more severe diseases and higher rate of morbidity and mortality in the elderly population. Therefore, they should receive influenza vaccine annually. However, the host response to vaccine is less in older individuals. On the other hand, selenium can act as a stimulator of the immune system and cause increased immunity and response to vaccine. This study was carried out to determine the effect of selenium on antibody production against influenza vaccine. By verifying this effect, selenium can be recommended as an adjuvant therapy in the elderly. Methods: A total of 110 subjects were selected at Infectious Diseases Research Center of Imam Reza Hospital in Kermanshah. They were divided into two groups of adjuvant (N=56) and placebo (N=54). The adjuvant group received influenza vaccine and selenium tablet. The placebo group received influenza vaccine and placebo tablet. Venous blood samples were taken before and four weeks after vaccination and the results were compared between the two groups. Results: Seroconversion, seroprotection, and geometric mean titer (GMT) for three strains (H1N1, H3N2, and B) were assessed. The seroconversion and GMT rates against influenza B vaccine component were significantly higher in adjuvant group than placebo group. Conclusion: Considering the ability of selenium in induction of a better response to influenza vaccine in older people as well as its low cost and accessibility, selenium can be used to increase antibody level in such cases.
Facial Expression Recognition Based on Convolution Neural Network

With the popularity of computer technology in people's daily life, facial expression recognition in the human-computer interaction, home entertainment, public safety and even medical applications in the field more and more widely. In recent decades, the rapid development of deep learning areas has brought new opportunities for breakthroughs in various fields. Unlike traditional methods of extracting features manually, researchers can obtain the characteristics of automatic learning and generalization through the method of machine learning. To avoid the complex explicit feature extraction process in traditional expression recognition, a convolutional neural network (CNN) for the facial expression recognition is proposed. Firstly, the facial expression image is normalized and the implicit features are extracted by using the trainable convolution kernel. Then, the maximum pooling is used to reduce the dimensions of the extracted implicit features. Finally, the Soft max classifier is used to classify the facial expressions of the test samples. Experimental results show the performance and the generalization ability of the CNN for facial expression recognition.

Gaussian Process Model-Based Short-Term Electric Load Forecasting Using Cuckoo Search

This paper deals with a Gaussian process model-based short-term electric load forecasting using cuckoo search. The Gaussian process model is a nonparametric model and the output of the model has Gaussian distribution with mean and variance. The multiple Gaussian process models as every hour ahead predictors are used to forecast future electric load demands up to 24 hours ahead in accordance with the direct forecasting approach. The separable least-squares approach that combines the linear least-squares method and cuckoo search is applied to train these Gaussian process models. The results of electric load forecasting for Kyushu district in Japan are shown to demonstrate the effectiveness of the proposed forecasting method.
