Ghrelin and Blood Pressure Regulation
Venue: Current Hypertension Reports

Ghrelin is a growth hormone releasing polypeptide that was first isolated from the rat stomach in 1999. High expression of growth hormone secretagogue receptor, the ghrelin receptor, in the heart, kidney, and blood vessels provides evidence of ghrelin activity in blood pressure regulation. Circulating ghrelin concentrations are reported to be inversely correlated with blood pressure, and the acute and chronic effects of ghrelin in decreasing blood pressure have been reported in animals with normal blood pressure, healthy individuals, animals and patients with heart failure, and animals with hypertension. The mechanism by which ghrelin regulates blood pressure appears to be related to modulation of the autonomic nervous system, direct vasodilatory activities, and kidney diuresis. Thus, modulation of the signaling pathway through ghrelin may provide a novel concept for treating hypertension. In this review, we discuss the current evidence and potential mechanisms of ghrelin activity in blood pressure regulation.
Compact Anonymous Hierarchical Identity Based Encryption with Constant Size Private Keys
Venue: Comput. J.

We present a new construction of anonymous hierarchical identity based encryption (HIBE) over prime order groups. The distinct feature of our proposed scheme is that both private key and ciphertext have a constant size, which has never been achieved in all other existing anonymous HIBE schemes. Moreover, we utilized a double exponent technique to generate the ciphertext in order to provide anonymity. This simple and efficient method allows us to construct a more compact anonymous HIBE in prime order groups. Under the decisional bilinear n 1 Diffie Hellman exponent assumption and linear assumption, we show that the proposed scheme is secure and anonymous against chosen plaintext attacks in the standard model.
An Efficient Adaptive ID Secure Revocable Hierarchical Identity Based Encryption Scheme
Venue: SmartCom

User revocation is an important functional requirement in hierarchical identity based encryption (HIBE) scheme from the point of practical applications. In this paper, we propose a revocable HIBE scheme with constant ciphertext size and prove it is semantic secure under the strong adaptive ID model by employing the recent dual system encryption methodology and predicate encoding technique.
Morphometric analysis of glenoid cavity of dry scapulae and its role in shoulder prosthesis

The lateral angle of scapula becomes truncated and broadened and form the glenoid cavity which shows variable morphology. There is a notch present on its anterosuperior part which gives its different shape. When this glenoid notch is indistinct its shape is piriform, when it is distinct it looks like inverted comma shape and when it is absent its oval shape. The shoulder joint is one among the most commonly dislocated joints in the body. The fracture of glenoid with dislocations is very common in the trauma. The detail knowledge about variation in anatomy of glenoid cavity like different shape, size and dimensions are important during designing and fitting of glenoid component for total shoulder arthroplasty. The objective of present study was to obtain anthropometric data of scapulae and the glenoid cavity specifically the diameters and various shape of glenoid belongs to population of Bihar and compare it to findings from other races of the world.  The present study was a cross sectional study which has been carried out on 228 undamaged dry adult human scapulae in which 126 belongs to right side and 102 belongs to left side. The age and gender of the bones used in the study was not predetermined.  The most common shape of glenoid cavity recorded in the present study was pear shape (50.44% followed by inverted comma shape (35.96% The least common shape was oval (13.6% The mean length of scapula was observed as 135.07+ 14.23mm, the mean breadth of scapula was 97.55+ 9.63 mm, the mean supero inferior glenoid diameter was 35.80+ 3.14mm, the mean antero posterior glenoid diameter 1 was 23.63+ 2.50mm, and the mean antero posterior glenoid diameter 2 was 16.17+ 2.24mm and mean glenoid cavity index was 66.40+ 8.14% In all the above measurements bilateral differences was not statistically significant.  The knowledge about the different shape and dimensions of glenoid are very important during designing and fitting of glenoid component for total shoulder arthroplasty. It is also helpful during evaluation of different pathological conditions like rotator cuff disease, osteochondral defects and Bankart lesion. Since the present study is conducted on a limited number of scapulae further cadaveric, radiological and clinical studies are indicated.

Venue: Journal of strength and conditioning research

Ong, JH, Lim, J, Chong, E, and Tan, F. The effects of eccentric conditioning stimuli on subsequent counter movement jump performance.  2016 The eccentric phase in a stretch shortening cycle is an important determinant of subsequent concentric performance, but there is little information on high intensity eccentric preconditioning. The purpose of this study was to determine the effects of varying degrees of eccentric conditioning stimuli on subsequent counter movement jump (CMJ) performance. Fourteen participants (age, 28.5 5.0 years; height, 172.7 6.7 cm; body mass, 74.3 11.9 kg) performed CMJ trials on 3 separate test sessions at least 96 hours apart in a crossover randomized counterbalanced study. Peak power (Ppeak) and vertical displacement (Dmax) were measured before and at 3, 6, 9, and 12 minutes (T3 12) postcontrol (0RM) 105% (105RM) and 125% (125RM) 1RM eccentric hip sled. The differences in vertical jump performance parameters between 0RM and eccentric preloading conditions (105RM and 125RM) and the differences within condition between control time point and posteccentric load time course T3, T6, T9, and T12 were analyzed for statistical significance via unequal variance t statistic. Statistical significance was set at p 0.05. Significantly higher Ppeak, compared with 0RM (4143 754 W) was seen at T3 and T6 in both 105RM (4305 876 and 4237 842 W) and 125RM (4314 848 and 4264 768 W) Compared with 0RM (42.2 7.8 cm) corresponding Dmax, was also significantly improved at T3 in both 105RM (44.5 7.3 cm) and 125RM (44.3 8.3 cm) and at T6 in 105RM (44.7 7.7 cm) Compared with baseline (43.2 7.2 cm) there was significantly higher Dmax at T3 and T6 in 105RM. In conclusion, high intensity preconditioning eccentric contraction at 105 and 125% 1RM was effective in improving CMJ power and height at 3 and 6 minutes after loading. Thus, power athletes and coaches can consider the application of eccentric preconditioning in warm up routines.
Unsupervised Deep Feature Extraction for Remote Sensing Image Classification
Venue: IEEE Transactions on Geoscience and Remote Sensing

This paper introduces the use of single layer and deep convolutional networks for remote sensing data analysis. Direct application to multi and hyperspectral imagery of supervised (shallow or deep) convolutional networks is very challenging given the high input data dimensionality and the relatively small amount of available labeled data. Therefore, we propose the use of greedy layerwise unsupervised pretraining coupled with a highly efficient algorithm for unsupervised learning of sparse features. The algorithm is rooted on sparse representations and enforces both population and lifetime sparsity of the extracted features, simultaneously. We successfully illustrate the expressive power of the extracted representations in several scenarios: classification of aerial scenes, as well as land use classification in very high resolution or land cover classification from multi and hyperspectral images. The proposed algorithm clearly outperforms standard principal component analysis (PCA) and its kernel counterpart (kPCA) as well as current state of the art algorithms of aerial classification, while being extremely computationally efficient at learning representations of data. Results show that single layer convolutional networks can extract powerful discriminative features only when the receptive field accounts for neighboring pixels and are preferred when the classification requires high resolution and detailed results. However, deep architectures significantly outperform single layer variants, capturing increasing levels of abstraction and complexity throughout the feature hierarchy.

English Vocabulary Size and Vocabulary Learning Strategies of UiTM Pre Diploma Students

Successful language learning depends crucially on a strong vocabulary. It is estimated that a vocabulary of 8000 word families is the necessary goal for English language learners who have to deal with unsimplified spoken and written texts. This study examined the English vocabulary size and vocabulary learning strategies of Mengubah Destini Anak Bangsa (MDAB) pre diploma students at the Segamat Campus of Universiti Teknologi MARA (UiTM) Johor. While some of these students had intermediate English language proficiency, the majority of them had low language proficiency. Data for the study were collected in three stages. Firstly, a Vocabulary Size Test was conducted to determine the students' vocabulary size. Secondly, a Vocabulary Learning Strategies Questionnaire was used to investigate the vocabulary learning strategies employed by the students. Finally, a semi structured interview was carried out with eight students as a form of triangulation that supplements the findings gleaned from the Vocabulary Learning Strategies Questionnaire. The quantitative data from the first two instruments were analysed using descriptive statistics, while interview analysis was performed to analyse the qualitative data from the semi structured interview. The findings revealed that only a very small number of the MDAB students had the desired vocabulary size of 8000 word families or more, and that they were medium users of vocabulary learning strategies. The findings on their vocabulary size suggest that many of them may not be lexically well equipped to successfully undertake a diploma programme of their choice at UiTM which uses English as its medium of instruction. In addition, the results of this study imply that some systematic vocabulary instructions and vocabulary learning strategies training should be introduced to help them improve their English vocabulary size.
Exploring Language Learning Strategies of Vietnamese University English and Non English Majors

This study compares language learning strategies (LLS) and their frequencies between Vietnamese English and non English majors. The Strategies Inventory of Language Learning (SILL) questionnaire from Oxford's 1990 taxonomy was employed as the main research instrument. The questionnaire was administered to 140 students at a public university in Vietnam. Semi structured interviews with ten students of both groups were also carried out to provide more qualitative information. The data analysis involved descriptive and inferential statistics and manual interview transcription. Both groups of students used a wide range of LLS across six strategy groups with metacognitive strategy group use the most frequent and compensation the least frequent. A significant difference was shown in the ways both groups employed LLS (p .05) Results from this study can provide a solid foundation for educational administrators and practitioners to better support these students and can add to an overall theory of LLS in Asia.

Labor Market Dynamics and Youth Unemployment in the Middle East and North Africa: Evidence from Egypt, Jordan, and Tunisia

Although it is well established in the literature that unemployment is a labor market insertion problem in the Middle East and North Africa (MENA) the dynamics driving youth unemployment remain poorly understood. Using panel and retrospective data from the Labor Market Panel Surveys in Egypt, Jordan and Tunisia, we are able to substantially improve our understanding of youth unemployment in MENA by studying flows into and out of employment and unemployment. We also decompose trends in the unemployment rates in Egypt, Jordan, and Tunisia over the past decade into the contributions of individuals entering unemployment from outside the labor force and from previous employment, and changes in the duration of unemployment these individuals experience. Models for the incidence and duration of unemployment illustrate the relationship between individuals' characteristics and their unemployment dynamics

RAS one equation turbulence model with non singular eddy viscosity coefficient

A simplified consistency formulation for Pk/e (production to dissipation ratio) is devised to obtain a non singular Cm (coefficient of eddy viscosity) in the explicit algebraic Reynolds stress model of Gatski and Speziale. The coefficient Cm depends non linearly on both rotational/irrotational strains and is used in the framework of an improved RAS (Rahman Agarwal Siikonen) one equation turbulence model to calculate a few well documented turbulent flows, yielding predictions in good agreement with the direct numerical simulation and experimental data. The strain dependent Cm assists the RAS model in constructing the coefficients and functions such as to benefit complex flows with non equilibrium turbulence. Comparisons with the Spalart Allmaras one equation model and the shear stress transport k o model demonstrate that Cm improves the response of RAS model to non equilibrium effects.
A one equation turbulence model for recirculating flows

A one equation turbulence model which relies on the turbulent kinetic energy transport equation has been developed to predict the flow properties of the recirculating flows. The turbulent eddy viscosity coefficient is computed from a recalibrated Bradshaw's assumption that the constant a1 0.31 is recalibrated to a function based on a set of direct numerical simulation (DNS) data. The values of dissipation of turbulent kinetic energy consist of the near wall part and isotropic part, and the isotropic part involves the von Karman length scale as the turbulent length scale. The performance of the new model is evaluated by the results from DNS for fully developed turbulence channel flow with a wide range of Reynolds numbers. However, the computed result of the recirculating flow at the separated bubble of NACA4412 demonstrates that an increase is needed on the turbulent dissipation, and this leads to an advanced tuning on the self adjusted function. The improved model predicts better results in both the non equilibrium and equilibrium flows, e.g. channel flows, backward facing step flow and hump in a channel.
Natural Interaction in Asymmetric Teleconference using Stuffed toy Avatar Robot
Venue: ICAT EGVE

In this paper, we propose an asymmetric teleconference system using stuffed toy robot as the representative of the remote user. Our main goal is to realize the system that can provide natural conversation both on the remote and the local side without immersing the user into a virtual environment. We consider envelope feedback gesture as the significant part to realize natural interaction, specifically turn taking, eye gazing and beat gesture. We use stuffed toy robot as the avatar robot because it can move very fast as well as increase familiarity and improve the interaction due to its softness structure. Furthermore, softness structure also brings safety and robustness because it will not be easily broken. In the remote side, we use wearable sensor and eye tracking sensor to capture remote user's movement, thus enabling him/her to move and interact naturally as well. We conducted the teleconference experiment to evaluate our system. The result suggested that our system can improve the experience of the teleconference, especially in turn taking aspect and transferring the beat gesture.
