A Semi-Analytical Model for the Subthreshold Behavior of FinFLASH Structures

Volume 17, Number 1, February 2007 Abstract—In this paper we present an original semianalytical model for the subthreshold electrical behavior of complex 3D structures as the SOI FinFLASH devices. This physically-based model, which does not need any fi tting parameter, solves the Poisson equation for a fi n covered by trapped charges in the active dielectrics. The analytical results are compared with fully 3D numerical simulations and a good agreement is obtained down to fi ns with very small feature sizes (order of tens of nm). This model can be effi ciently used to gain information on important cell electrical behaviors as the threshold voltage shift ∆Vth and the subthreshold slope factor S.
Hotel Employees ’ Perceptions of Stress Factors

Accommodation enterprises are accepted to be highly stressing environments due to working conditions such as their labour-intensive structure, employees’ direct encounter with the customers and long working hours. It is required to diminish the stress factors employee face down to acceptable levels in order to increase the productivity of employees, get them motivated and attached. This can be achieved in a great extent by understanding the stress factors at the work place and take precautionary steps accordingly. The aim of the study is to analyze the perceptions of non-managerial employees towards the stress factors caused by the characteristics of the job and to investigate variations in stress perceptions according to variables such as age, gender, marital status, education level, departments and experience in the working place. When the perceptions of the respondents analyzed as a whole study findings indicate that most of the job characteristics create stress on the employees. It is also found that there are no significant differences between the groups on the perceptions of stress factors. Based on the findings, the study offers suggestions on diminishing the pressure of stress factors on the employees.
A Framework and Tools for Modeling and Simulating Societies as Evolutionary Complex Systems

This paper presents a framework and tools for modeling and simulating societies as evolutionary complex systems. In this paper, we introduce an object-oriented computational modeling for social sciences in order to model and simulate complex systems where the model framework, “Boxed Economy Foundation Model”(BEFM), is proposed. Moreover, in order to support making conceptual and simulation models based on BEFM, “Component Builder” (CB) is proposed. It is the tool to generate the program code just by making the diagram and setting the parameters with a graphical user interface. In addition, the componentbased software system “Boxed Economy Simulation Platform”(BESP) is proposed for simulating and analyzing a model. The example shows that our proposed framework and tools are quite powerful and have the potential for supporting thinking about complex societies.
SEXUAL DIMORPHISM IN THE EASTERN HELLBENDER ( CRYPTOBRANCHUS ALLEGANIENSIS ALLEGANIENSIS )

—Sexual dimorphism is common in vertebrates that exhibit male-male combat. The Eastern Hellbender, Cryptobranchus a. alleganiensis, exhibits such combat and sexual dimorphism has been reported. The most easily discernable dimorphic character, swelling around the cloaca in males, is detectable only during and around the autumn breeding season. We used univariate and multivariate analyses to determine if other morphological characters could be used to determine the sex of adult hellbenders outside the breeding season. We analyzed six morphological features of 105 preserved specimens and found that males differed significantly from females in snout-vent length, thoracic girth, and mass. However, the differences detected were not sufficient to allow positive determination of sex of an individual. Although hellbenders exhibit sexual dimorphism in several morphological characters, the only reliable external morphological character is the presence of swelling around the cloaca of males during the autumn breeding season.
Mechanical Parameters and Bearing Capacity of Soils Predicted from Geophysical Data of Shear Wave Velocity

The analysis of foundation vibrations and earthquake problems in geotechnical engineering demands characterization of dynamic soil properties by geophysical techniques. Also the dynamic structural analysis of the superstructures needs knowledge of the dynamic response of the soil-structure, which, in turn depends on dynamics properties of soil. The estimation of seismic velocities, modulus of elasticity and structural properties of soils is not enough in the design of engineering projects. Therefore, an ultimate bearing capacity has been predicted using the seismic shear wave velocity. It is indicated that the allowable bearing pressure and the coefficient of subgrade reaction together with many other elasticity parameters may be obtained rapidly and reliably once the seismic wave velocities are determined in situ by convenient geophysical survey. In this study, the data for S and P-waves velocities collected from seismic investigation reports in the different soil deposits of Iraq. Use was made of the mathematical correlations connecting several parameters and wave velocities for studying the layers of soil presented in Iraqi areas. The soil elastic constants together with the allowable bearing capacity, and other parameters were obtained and discussed. It was indicated that for cohesive and cohesionless soils, up to a shear wave velocity of 300 m/s and 400 m/s respectively, the shear wave velocity may predicts the bearing capacity relatively well.

Much less is known about the beneficial effects of statins on acute erioperative cardiovascular events. The purpose of this study was to determine hether preoperative statin therapy is associated with a reduced risk of early ardiac death or nonfatal, in-hospital postoperative myocardial infarction after rimary, elective coronary artery bypass graft surgery requiring cardiopulmoary bypass.
SMALL-ANGLE SCATTERING FROM DETERMINISTIC MASS AND SURFACE FRACTAL SYSTEMS

Structural properties of deterministic mass and surface fractals are studied using smallangle scattering (SAS; X-rays, neutrons) method. The corresponding scattering curves are analyzed in momentum space. The scattering amplitude form a surface fractal can be written as a sum of amplitudes of composing mass fractals. We show that when the distances between scattering units are much larger than their overall dimension, the scattering from a surface fractal can be explained, in a good approximation, in terms of a power-law distribution of the scattering units. We illustrate the above findings on randomly oriented and non-interacting 2D mass and surface fractal systems whose scattering units are equilateral triangles. In our model, the scattering units of the mass fractal are triangles of equal sizes composing the well-known Koch snowflake. For the surface fractal, a sum of triangles of different sizes is considered to form the Koch snowflake.
American Mineralogist — “ Outlooks ” — Submitted

9 Traditional pathways to discovery in Earth sciences rely in large measure on deductive 10 and inductive approaches, by which measurements and observations are made in the 11 context of established principles or testable, predictive hypotheses about the natural 12 world. Vast, but largely untapped, Earth and life science data resources offer a potentially 13 revolutionary alternative “abductive” approach to investigate Earth’s co-evolving 14 geosphere and biosphere. We therefore advocate a strategic, data-driven program for 15 accelerated scientific discovery. 16 17
SHU Social Science and Business Administration Programmes Communicating Corporate Identity in International Hospitality Organisations

The aim of this study is to investigate how international hospitality organizations (IHO’s) are communicating its corporate identity. Issues regarding corporate identity are crucial for the survival of IHO’s, and if it is managed well it will serve as a competitive advantage. Two case studies are used to elucidate the research purpose: Scandic Hotels and Radisson SAS. These two cases provide insights on how corporate identity is managed in the hospitality industry. Information from both organizations has been collected through interviews and evaluated descriptively. How IHO’s are planning its corporate identity communication strategically from a managerial perspective will be described. The findings show that a corporation’s brand name is the most important visual tool for IHO’s. However, the importance of using as many tools as possible, together with the importance of consistent and coordinated communication efforts following a red thread in order to transfer the correct message, will be highlighted. Finally, how IHO’s mainly through training implement the corporate identity internally will be portrayed. Furthermore, the usefulness of Intranet for such training will be presented.
THE E-NEGOTIATION AS A TOOL FOR LOGISTICS OPTIMIZATION IN AN INDUSTRIAL DISTRICT

The aim of this work is to find an optimal solution to operational planning of freight transportation in an industrial district. More specifically, we propose an architecture that drives agents, that is firms in the industrial district, to negotiate in logistics field to minimize the total transportation and environmental costs. The idea is to achieve logistics optimization setting up a community made of district enterprises. We address the situation in which a centralized coordinator helps the agents to reach an agreement, while preserving a satisfactory level of system efficiency and fairness. The implemented algorithm uses the fuzzy aggregation criteria to improve the logistics system performance. The objectives are: maximizing customer‟s satisfaction, and minimizing the number of trucks needed. A fuzzy clustering algorithm (FCM) and a Fuzzy Inference System (FIS) are thus proposed to achieve these objectives. The proposed framework can be used to provide real time solutions to complex practical logistics and negative environmental impacts.
Risk Assessment of Intrusion Scenarios Using DS Evidence Theory

In the paper, an online risk assessment model based on D-S evidence theory is presented. The model can quantitate the risk caused by an intrusion scenario in real time and provide an objective evaluation of the target security state. The results of the online risk assessment show a clear and concise picture of both the intrusion progress and the target security state. The model makes full use of available information from both IDS alerts and protected targets. As a result, it can deal with uncertainties and subjectiveness very well in its evaluation process. In IDAM&IRS, the model serves as the foundation for intrusion response decision-making.
Effect of Bacillus circulans bacteria on availability of potassium from different sources on the productivity and quality of pepper under saline soil conditions

A field experiment was carried out at the two successive seasons of 2016 and 2017 in privet farm at El-Rowad village belong to Sahl El-Hussinia, El-Sharkia Governorate, to study the impact of potassium fertilizers combined with or without Bacillus circulans bacteria on productivity and quality of pepper plants (Capsicum annuum L.) grown under saline soil conditions. A split plot design was used with six replicates for each treatment. After four weeks transplanting plants in filed experiment were divided into two divisions. In the first one the plants were treated with Bacillus circulans strain as potasssium solubilizing bacteria (KSB) to increase the availibily of potassium from different sources and the second part was without bio-fertilizer (Bacillus circulans) treatment. The potassium fertilizer sources were used as; potassium silicate, potassium sulphate and potassium humate at different rates namely 0, 2 and 4 ml/L. The results showed that the foliar application of potassium of different sources and rates improved plants growth as indecated by plant length, number of branch, diameter and yield of fruit especially plants sprayed with potassium humate combined with or without B. circulans. Pepper plants quality i.e total chlorophyll, proline and vitamin C contents showed also the same positive responses as compared to the untreated plants. Also, the concentrations of N, P, K, Fe, Mn and Zn in fruit pepper were increased with increasing the rate of application of different potassium sources combined with B. circulans especially plants treated with potassium humate. The soil treated with different sources and rates of potassium fertilizers individual or combined with KSB led to decrease both soil pH and salinity, meanwhile, avaliable N, P, K, Fe, Mn and Zn in soil solutions were increased. From our result we highly recommended to use potassium humat in various rates and in combination with Bacillus circulans strain to improve the soil properties and hence the plant growth of pepper.
The Evolution of Degree Distribution , Maximum Cliques and Maximum Independent Sets of Company Co-Mention Network over Time

The main subject of our research is the characteristics and features of the economic and finance news flow. In this paper we construct company co-mentions network as a graph in which nodes serve as the world’s largest companies mentioned in financial and economic news flow. We link two nodes if two companies were mentioned in the same news item. We construct company co-mention networks for 72 consecutive monthly periods to analyze the dynamics of the structural properties of the company co-mentions network over time. These structural properties are examined based on different graph characteristics such as the distribution of the degrees of the vertices in this graph as well as maximum clique and maximum independent sets sizes. Some conclusions are derived with respect to the dynamics of the evolution of the company comentions network over time. Key-Words: graph properties; social networks; degree distribution; market graph
Analysis and evaluation of classification models for disease detection using human gut metagenomic data

The gut microbiota is an important contributor to human health and disease. We harbor a large number of microorganisms in our gastrointestinal tracts, 10 times more cells than our own human cells. The gut microbiota is an important modulator of the immune system and an important metabolic organ. In several diseases, the taxonomic and functional composition of the microbiota is altered compared to a normal healthy microbiota [1],[2]. Metagenomics, sequencing of a pool of DNA extracted from microbiota samples, is an excellent tool to study the functional and taxonomic composition of the microbiota. The aim in this project is to develop and evaluate a statistical classifying models using taxonomic and functional data derived from metagenomic sequences. Such a model could for example predict the risk of colon cancer based on data from the gut metagenome. We obtained a data set of human gut metagenomics data available online [3]. This data is characterized by high number of attributes which prevails on number of instances. Firstly, we followed the pipeline of the original paper and reproduced its results using lasso. Next, we are exploring the ways to improve classification performance and evaluate variable importance to determine which bacteria can be CRC markers. Using filter feature selection with SVMs we raised AUC from 0.85(lasso) to 0.89 on the test set. Random Forests classifier gives AUC of 0.87 and verifies the importance of several bacteria species, namely Fusobacterium nucleatum and Peptostreptococcus stomatis, which were highlighted in several studies [3],[4],[5] and by correlation and entropy based feature selection methods. We also check for the absence of the influence of confounders such as age, gender and body mass index and conclude that there is no significant effect of those factors in this study.
Analyzing the Comparison in terms of Optimal BaseStation Positions and Network Lifetime of theBenchmark Protocols in Wireless Sensor Network:Homogeneous and Heterogeneous LEACH with HEED

A wireless sensor network (WSN) comprises of numerous autonomous tiny devices called sensor nodes spread in a particular area. The nodes are capable of monitoring the ambient conditions and then passing the related data through the network from various different locations to a main location. The efficient energy utilization is one of the important performance factors for wireless sensor networks survivability as the nodes operate with limited battery power. In this paper, we have given a comparative study of three clustering based benchmark protocols called LEACHhomogeneous, LEACH- heterogeneous and HEED for wireless sensor networks on the basis of base station position and network lifetime.
J un 2 01 9 Robust minimal matching rules for quasicrystals

We propose a unified framework for dealing with matching rules of quasiperiodic patterns, relevant for both tiling models and real world quasicrystals. The approach is intended for extraction and validation of a minimal set of matching rules, directly from the phased diffraction data. The construction yields precise values for the spatial density of distinct atomic positions and tolerates the presence of defects in a robust way.
Structure characterization and tribological study of magnetron sputtered nanocomposite nc-TiAlV

Grown by reactive unbalanced magnetron sputtering in a mixed N2 and CH4 gaseous medium, heterogeneous nanocomposite coatings in the Ti-Al-V-N-C system show extraordinarily excellent tribological performance of coated machining tools. Using analytical high resolution TEM, EELS, FEG-SEM, XRD, and Raman spectroscopy, this paper reports detailed structural and chemical characterization of the coatings grown at various CH4: N2 ratios. Meanwhile, the mechanical and tribological properties were also measured, including hardness, Young’s modulus, residual stress and the dry-sliding friction and wear at varying environmental humidity. When CH4 gas was introduced in the deposition, the structure of the coatings has been found to experience a change from nano-scale TiAlN-VN multilayer architecture to a complex mixture of columnar grains of nc-TiAlV(N,C)/a-C nanocomposites and inter-column network of sp2-type amorphous carbon. Carbon incorporation and segregation also shows remarkable influence on the columnar growth model by leading to finer grain size. As compared to the carbon-free nitride coating, the nanocomposite coatings showed substantially reduced residual stress owing to the freecarbon precipitation, whereas the coatings maintained comparable hardness to the carbon-free TiAlN/VN. Their tribological properties were found to be strongly dependent on the environment. In humid air at RH > 30%, the coatings showed low friction coefficient less than 0.4 and extremely low wear rate at a scale of ~10-17 m3N-1m-1. Q. Luo, S.C. Wang, Z. Zhou, L. Chen, J. Mater.

Experimental Detection of the Average Motor Unit Action Potential Frequency by Means of Surface Electromyogramm

We present here experimental records of surface electromyogramms (sEMG) and it’s average power spectra. We demonstrate that the de tailed analysis of all sEMG power spectra reveals significant peaks at the characteristic position. This position can be associated with the average repetition rate of a single motor unit action potential. Also, we prove here the possibility to measure the dependence of the myo-pulse repetition rate on the muscle mechanical load.
Human papillomavirus and the risk of oral potentially malignant disorders of betel-quid chewers in samosir island, Indonesia: an integrated epidemiologic and molecular study

Human Papillomavirus (HPV) is known to be associated with oral cancer and several types of oral potentially malignant disorders. Recent studies have shown that HPV oncogenes act synergistically with a common risk factor of chemical carcinogens in betel-quid chewing, resulting in oral malignant transformation. The aim of the present study was to investigate the association between HPV with the risk of oral potentially malignant disorders of betel-quid chewers. This case-control study was performed on habitual chewers of betel-quid, surrounded the working area of the local government clinic of Ambarita, regency of Samosir province of North Sumatra, Indonesia. As case group, 28 subjects with oral potentially malignant disorders and as control group, 23 subjects without oral potentially malignant disorders, were assigned into study. All HPV DNA samples were collected by swabing over the oral lesions and mucosa, thereafter performed using nested-polymerase chain reaction. Fisher exact test and multiple logistic regression were used to investigate associations between variables. The present study noted a high prevalence of positive HPV, both in case group (96.4%) and control group (82.6%). Positive HPV increased the risk of oral potentially malignant disorders of betel-quid chewers, but the association was not statistically significant (OR= 5.684; p= 0.162). As the conclusion, the present study highlighted a high prevalence of positive HPV on betel quid chewers in Samosir island Indonesia. Larger studies in this population with both evaluation of low risk and high risk HPV types, were recommended to detect HPV types with more valid empirical associations.
Effects of 3 D Rotational Jitter and Selection Methods on 3 D Pointing Tasks

3D pointing is an integral part of Virtual Reality interaction. Typical pointing devices rely on 3D trackers and are thus subject to fluctuations in the reported pose, i.e., jitter. In this work, we explored how different levels of rotational jitter affect pointing performance and if different selection methods can mitigate the effects of jitter. Towards this, we designed a Fitts’ Law experiment with three selection methods. In the first method, subjects used a single controller to position and select the object. In the second method, subjects used the controller in their dominant hand to point at objects and the trigger button of a second controller, held in their non-dominant hand, to select objects. Finally, subjects used the controller in their dominant hand to point the objects and pressed the space bar on a keyboard to select the object in the third condition. During the pointing task we added five different levels of jitter: no jitter, ±0.5°, ±1°, and ±2° uniform noise, as well as White Gaussian noise with 1° standard deviation. Results showed that the Gaussian noise and ±2° of jitters significantly reduced the throughput of the participants. Moreover, subjects made fewer errors when they performed the experiment with two controllers. Our results inform the design of 3D user interfaces, input devices and interaction techniques.
