An Eye Tracking Study of Viewing Behaviour and Preferences of Arabic, English and Chinese Users

The aim of this research is to investigate possible variations in visual behaviour and eye movements on webpages among users from three different cultures (Arab, English and Chinese). The paper reports an experiment using eye tracking technique and questionnaire to understand how users from different countries fixate on webpages with different layouts and which type of layout they preferred. Thirty users from each group were exposed to three types of webpage (image-based, text-based and a webpage with unfamiliar design). The results indicated similarities and differences in fixations between the three cultural groups. Dissimilar scanning patterns were exhibited from each group. This study also revealed differences in preferences across Arab, English and Chinese users. This study contributes to the field of Human Computer Interaction by providing new insights into the similarities and differences between the users from the Middle East, the West and the Far East from the perspective of visual behaviour and preferences.

Report Data Centers in the Wild : A Large Performance Study

With the advancement of virtualization technologies and the benefit of economies of scale, industries are seeking scalable IT solutions, such as data centers hosted either in-house or by a third party. In spite of the ubiquity of data centers, little is known about their inproduction performance. This study fills this gap by conducting a large scale performance survey on several thousands of data center servers within a time period that spans two years. We provide in-depth analysis on the diversity and time evolution of existing data centers by statistically characterizing typical data center server workloads, highlighting similarities and differences in the usage of basic resource components, including CPU, memory, disk, and file system. In addition, we quantify the time variability and seasonality of resource demands and how they are changing according to different geographical locations as well as virtual and physical operating systems. This survey provides a baseline for workload calibration, which is critical for the development of scalable and efficient resource management and capacity planning of future data centers.
REGIONAL DISPARITIES AND SOCIAL COHESION POLICIES . THE CASE OF THE METROPOLITAN AREA OF BARI ( ITALY )

The role of Regions appears reconfigured by the “reshaping” of national States. Besides, under a sub-regional scale, forms of governance have been launched, redefining a new territoriality. In Italy, the role of the Regions and Cities is more and more important in the decision-making processes of the territories and it is also characterized by the recent establishment of the metropolitan cities, but still not geo-politically defined. There is, in fact, a constitutional reform process through the region’s reorganization legislative autonomy and strengthening of local governments. In this context, some areas are characterized by social unrest that includes new forms of poverty, urban malaise and marginalization, due also to the financial and economic crisis whose signs of recovery are still very weak. In the European Union, the programming decisions considered the policy of development and cohesion also at the local scale. The 2014-2020 EU programming cycle, in fact, has defined the main role of metropolitan cities, but also of cities and internal areas. The contribution will analyze Puglia, region of southern Italy, and the metropolitan area of Bari, the regional capital, in order to verify policies concerning the social field, both through “strategic planning” and launching the so-called “smart city” experience. In the metropolitan city, indeed, there is already an orientation towards the "social innovation" to address the issues of social cohesion and inclusion, consistent to sustainable development.
The Emerging Pattern in Prostate Cancer in Zimbabwe

Background: Prostate cancer has become the leading cancer and cause of death in Zimbabwean men. The number of confirmed prostate cancer cases has been on the increase since the turn of the century. Considering this trend a retrospective cross sectional study was carried out to determine the pattern of the disease and the role played by the prostate specific antigen in its detection. Objectives: The aim of the study was to determine the emerging pattern and the role of the prostate specific antigen in the detection of prostate cancer. Methodology: A retrospective cross sectional study using secondary data was carried out. Prostate specific antigen results of 176 outpatients who visited a small medical facility in the Midlands Province of Zimbabwe were retrieved. Of these 26 proceeded to have biopsies done and the histology reports were retrieved and analyzed. The data was analyzed using Graph Pad Prism 6 software. Results: 14.2% of the patients were confirmed by biopsy to have prostate cancer. Prostate specific antigen levels of greater than 20 ng/ml were associated with biopsy confirmed Prostate Cancer. Conclusion: It was found out that Prostate Cancer is a major health problem in Zimbabwean men. Despite the low specificity of the prostate specific antigen, the test still plays a major role in the detection of prostate cancer. The age of those with confirmed Prostate Cancer is going down. There is need for improved health budget and public health education in Zimbabwe.
Shaping space: facial asymmetries in fifth-century Greek sculpture

The phenomenon of optical correction in Classical Greek sculpture has been attested by both ancient authors and modern scholars. Despite the apparent normalcy of optical correction in sculpture, however, there are no obvious reasons for it and how such correction worked in statues is a question which has rarely been examined systematically. Among the possible explanations are conscious application of philosophical or optical theories by sculptors, or subconscious influence of human visual perception on the carving process. In this study, asymmetries (as one possible method of achieving optical correction) in the heads of extant fifth-century Greek sculpture have been analysed in relation to the ideal view and the pose of statues. All heads that were measured were asymmetrical, but statistical analysis showed no systematic pattern in the data that could be considered representative for sculpture from Classical Greece in general. The lack of a statistically significant pattern means that (subconscious) correction of visual perception is not at the root of the asymmetries, undermining the notion of systematic application of contemporary optical theory by sculptors or the influence of their own visual perception. However, a practical explanation for the unsystematic asymmetries presented itself through interviews with seven sculptors, who pointed out technical reasons why asymmetries would occur naturally during carving, without influence of theoretical designs or visual perception.
Broadband SiGe∕Si quantum dot infrared photodetectors

The broadband absorption of metal-oxide-semiconductor SiGe∕Si quantum dot infrared photodetectors is demonstrated using boron δ doping in the Si spacer. The peak at 3.7–6μm results from the intersubband transition in the SiGe quantum dot layers. The other peak at 6–16μm mainly comes from the intraband transition in the boron δ-doping wells in the Si spacers. Since the atmospheric transmission windows are located at 3–5.3 and 7.5–14μm, broadband detection is feasible using this device. The δ doping in SiGe quantum dots and Si0.9Ge0. 1 quantum wells is also investigated to identify the origin of the absorption.
Preservatives in cosmetology : A review of parabens

Parabens are the preservatives most commonly used in cosmetics, foods, and drugs (Elder, 1984). They have been the subject of numerous studies that have established not only their broad spectrum of action against numerous micro-organisms, but also their efficacy, stability, and their lack of side effects. Despite these studies, a controversy surrounding parabens has been mounting since 2004. As a result, the consumer is today demanding products that are paraben-free.
Sensor-integrated instruments for surgical quality assurance and process monitoring

Demographic changes will increase the number of surgical procedures in the next years. Therefore, quality assurance of clinical processes, such as the reprocessing of surgical instruments as well as intraoperative workflows will be of increasing importance to ensure patient safety. Surgical procedures are often complex and may involve risks for the patient. For fixation of screws, e.g. in case of pedicle screws, osteosynthesis plates or revision joint replacement surgery implants, the application of defined torques may be crucial in order to achieve optimal therapeutic results and minimal complication rates. In many cases a subjective rating of the surgeon is necessary as no adequate instrumentation is available. With the same subjective feeling, hammering or screwing in are performed to implant e.g. the acetabular component in THA. Our actual work is dedicated to the implementation of a functional prototypes of sensor- integrated instruments for specific types of intervention (especially in traumatology).
ASSOCIATIONS OF PIT-1 GENE POLYMORPHISM WITH MILK YIELD AND COMPOSITION TRAITS IN BROWN SWISS CATTLE

The present study investigated the genetic variability of Pit-1 polymorphisms (HinfI_451 bp) in a total of 301 Brown Swiss cattle, and also evaluated the possible association between the Pit-1 genotypes and dairy traits such as 305 days milk yield (MY305), test day milk yield (TDMY), fat (%), protein (%), lactose (%), density (kg/m 3 ), solids-non-fat (%), total solids (%), freezing point ( o C), and also pH and conductivity (uS/cm) of milk. Allele frequencies were found as A: 0.374 and B: 0.626 in HinfI (451 bp) polymorphism in Pit–1 gene. No significant difference was detected between the observed and the expected genotype frequencies via Hardy-Weingberg equilibrium (P>0.05). The effect of Pit-1 polymorphisms (HinfI_451 bp) was not observed on milk yield and composition in Brown Swiss populations (P>0.05). The results demostrated that the Pit -1 polymorphisms (HinfI_451 bp) could not be exploited as a candidate gene for selection of dairy traits in Brown Swiss cattle.
The Molecular Mechanism of Alginate O-Acetylation in Pseudomonas aeruginosa

Pseudomonas aeruginosa is an opportunistic, gram-negative pathogen that is involved in a variety of infections. The bacterium secretes and chemically modifies alginate to form a protective biofilm matrix. One protein implicated in the O-acetylation of alginate is AlgJ. In this study, we have successfully crystallized AlgJ and determined its structure to 1. 83Å. The structure reveals that AlgJ is a SGNH hydrolase-like protein. AlgJ possesses a Ser-Asp-His catalytic triad which suggests that AlgJ is catalytically active. The structure of AlgJ demonstrated that the previously identified conserved residues of the AlgJ signature motifs form a local network with the proposed catalytic triad and are important for alginate O-acetylation in vivo. We have assayed the proposed Ser-Asp-His catalytic triad in vitro and observed impairment in acetyl esterase activity. In vitro binding studies demonstrated that AlgJ was unable to bind polymannuronate and that was it not capable of O-acetylating the polymer.
The Effect of L1 Prosody in the Perception and Production of Non-native Lexical Stress

The present study examined perception and production of English lexical stress by Cantonese and Mandarin late learners of English. Perception was tested with an ABX stress discrimination task, and production was tested with a real word repetition task. Stimuli were English real words consisting of 17 stress minimal pairs. Perception results did not reveal significant between-group differences, but suggested that Mandarin speakers were slightly better at perceiving stress contrast than Cantonese speakers. Production results showed that both Mandarin and English speakers demonstrated a higher stress contrast than Cantonese speakers in terms of duration. All language groups showed a similar degree of stress contrast in F0 and intensity. It is suggested that Mandarin speakers would benefit from their use of neutral tone and demonstrate a better ability perceiving and producing non-native lexical stress. The hypothesis is that perception and production of lexical stress is not only determined by early experience with lexical stress but could also be influenced by the speakers’ L1 prosodic features.
Team MuCAR-3 at C-ELROB 2009

This paper briefly describes the hardand software system of TAS/UniBw’s entry for the 2009 C-ELROB robotic trials, participating at the autonomous navigation scenario. At the core of the system is the so-called tentacles approach to reactive robot navigation, that we already demonstrated successfully at the 2007 C-ELROB trials. Since then, the basic tentacles approach has been extended in many ways. We outline an efficient method for accumulating 3D LIDAR data into multi-layered occupancy grids to be used for tentacle evaluation. We then show how to combine obstacleavoidance and path following behavior within the reactive tentacles approach. Finally, we show how visual information can be used for tentacle evaluation and ERI-Card detection.
Methods for the Screening and Treatment of Spinocerebellar Ataxias

Spinocerebellar ataxias (SCAs) are a heterogeneous group of inherited neurodegenerative disorders that occurs in autosomal dominant manner. The disease shares the similar molecular mechanism as other neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease in which mutant protein form due to defective/ mutant DNA, these proteins accumulate inside neuronal cells and cause Neurodegeneration. The disorders affect mainly cerebellar regions, cerebellar connections, and its associated pathways in addition to other brain regions. The general characteristics of SCAs are cognitive impairment, depression, and motor deficits. The most prominent symptom observed in SCAs patients is ataxia with other varying non-ataxia symptoms in the majority of phenotypes. The modern classification strategies of the disorder is based upon expanding genotype. Due to overlap in clinical manifestation of many SCAs types, Genetic test, and various screening tools, for instance, Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET) and Electromyography used to confirm the accumulation of mutant protein and aberrant neuronal mechanism responsible for the causation of particular phenotype. Nucleotides repeat expansion which is the basis of genetic disorder of SCAs can be determine by sequencing procedure. Similarly, techniques such as polymerase chain reaction (PCR) and gel electrophoresis with other molecular techniques and appliances used for the screening of patients in large number. The aim of this study was to explore the methods available for the screening of SCAs which form the basis of differential genetic diagnosis and list all the distinguishable clinical features and treatments available for SCAs.
Climate and trade policies: from mutual destruction to mutual support

Abstract There is no doubt that trade and climate policies can be mutually destructive. But there are three strong reasons to suggest that they can also be mutually supportive: they have a common problem, common foes, and common friends. Mutual support would be much stronger if the world regimes for these two policies shared a few common principles. The climate community should feel at ease with the broad WTO principles of ‘national treatment’ and ‘most-favoured nation’, and rely on them in building its own treaty and institutions. The trade community should grasp the opportunity to benefit from the better disciplines on adjustment policies that it is hoped the climate community will design. These conclusions should put the many pending problems into a more positive perspective, and persuade negotiators to find pragmatic compromises, as was the case with the GATT. Using this perspective, the paper focuses on a few key issues, such as the definition of carbon border taxes and the reasons to ban carbon tariffs. Other cases of mutual support are examined. For instance, the climate community should not repeat the mistakes of the world trade regime in dealing with the developing and least developed countries.
Topic Detection Based on Weak Tie Analysis: A Case Study of LIS Research

Abstract Purpose Based on the weak tie theory, this paper proposes a series of connection indicators of weak tie subnets and weak tie nodes to detect research topics, recognize their connections, and understand their evolution. Design/methodology/approach First, keywords are extracted from article titles and preprocessed. Second, high-frequency keywords are selected to generate weak tie co-occurrence networks. By removing the internal lines of clustered sub-topic networks, we focus on the analysis of weak tie subnets’ composition and functions and the weak tie nodes’ roles. Findings The research topics’ clusters and themes changed yearly; the subnets clustered with technique-related and methodology-related topics have been the core, important subnets for years; while close subnets are highly independent, research topics are generally concentrated and most topics are application-related; the roles and functions of nodes and weak ties are diversified. Research limitations The parameter values are somewhat inconsistent; the weak tie subnets and nodes are classified based on empirical observations, and the conclusions are not verified or compared to other methods. Practical implications The research is valuable for detecting important research topics as well as their roles, interrelations, and evolution trends. Originality/value To contribute to the strength of weak tie theory, the research translates weak and strong ties concepts to co-occurrence strength, and analyzes weak ties’ functions. Also, the research proposes a quantitative method to classify and measure the topics’ clusters and nodes.
Techniques used in orally disintegrating drug delivery system

Formulation of a convenient dosage form for administration, by considering swallowing difficulty and poor patient compliance, leads to development of orally disintegrating tablets. This are also called as orodisperse, mouth dissolving, rapidly disintegrating, and fast melt system. This disintegrates in the mouth in seconds without chewing and the need of water which is advantageous mainly for pediatrics, geriatrics and patients having difficulty in swallowing tablets and capsules. Conventional preparation methods are spray drying, freeze drying, direct compression, Molding, and sublimation while new technologies have been developed for the production of orodispersible tablets. This review depicts conventional and recent technologies that are used to prepare orodispersible tablets in detail. Keywords: Orally disintegrating tablet; Superdisintegrant; Patented technologies; Orodispersible tablets
Fault spectrum analysis for fast spare allocation in reconfigurable arrays

Repairing a reconfigurable array by row and column replacement using SR rows and SC columns was shown to be an NP-complete problem. In order to reduce the search time, the authors propose to apply a three phase procedure. In the first phase, they suggest using a heuristic to find good, but not necessarily optimal, feasible cover for the faulty array. Only if the heuristic method fails to generate a feasible cover, the array is examined to find out whether it is repairable at all. If deemed economical, repairable chips will undergo an exhaustive analysis. This three phase strategy can considerably reduce the average time for repair analysis. Searching for a good heuristic to be applied in phase 1, the authors investigated the fault distribution pattern on the faulty array and considered the effect of a row or column replacement on this fault distribution. Accordingly, a k degree fault spectrum for a bipartite graph is defined and a maximum spectrum is introduced as a heuristic for selecting vertices. They prove that the vertices which are most likely to be included in the feasible cover will be selected by heuristic. Consequently, a fast method to generate a feasible cover is proposed and a suitable algorithm is developed. <<ETX>>
Application of CD 34 + Human Peripheral Blood Stem Cell is Able to Increase Fibroblast and Collagen in Skin of a Male Ultraviolet B Exposed Rat

The decrease of fibroblast cells and collagen is one of the symptoms of skin degeneration caused by ultraviolet exposure. The aim of this research is to find out the effect of CD34 Human Peripheral Blood Stem Cell (HPBSC) application subcutaneously towards the amount of fibroblast cells and collagen on a male ultraviolet B exposed Wistar rat. This is an experimental research using Randomized Posttest Only Control Group Design method. Two groups of male wistar rats, each consisting 18 rats were exposed to ultraviolet ray for 4 weeks. The first group was given subcutaneous injection of Phosphate Buffered Saline (PBS) solution, meanwhile the second group was given CD34 HPBSC subcutaneously. After 4 weeks, a histopathology – anatomy slide of the rat skin was observed to find out the amount of fibroblast cell and collagen. The result came out to be finding regeneration of fibroblast cell and collagen. Independent t test on the amount of fibroblast is 5,53;p= 0,001 and on amount of collagen is 7,05; p= 0,001. The application of CD34 HPBSC subcutaneously is able to increase the amount of fibroblast cell and collagen on male wistar rat’s skin which has been exposed by ultraviolet B ray. Clinical tests still has to be carried out before applying this to human skin.
A Note on Authenticated Key Exchange in Cryptocurrency

: In this paper we focus on how to realize end-to-end secure communication between cryptocurrency users. While a cryptocurrency users have not only (cid:12)nancial transactions but also commercial transactions (e.g., acknowledgment of receipt, follow-up correspondence, etc), a cryptocurrency only guarantees the security of (cid:12)nancial transactions. If we want to get end-to-end security, we need another long term key to execute authenticated key exchange(AKE), but It is wasteful to require two long term keys. In order to solve this problem, a bitcoin-based authenticated key exchange protocol was proposed by Patrick McCorry et al. This protocol executes all interactions by the same keys. However, this protocol has the following ineﬃciencies; 1) Request a unnecessary payment to generate a session key, and 2) unable to prove the security in a formal model. To overcome the above inef-(cid:12)ciencies, we present a new protocol that achieves secure commercial transactions as well as secure (cid:12)nancial transactions. Our protocol never requests any extra long term keys, any extra payments and any trusted third parties. We prove the security of our protocol in the Canetti-Krawczyk model.
Obstacle Detection and Avoidance Methods for Autonomous Mobile Robot

: In Recent Trends, Robotics plays a major role in manufacturing, mining, warfare, surgery, Education, Entertainment and other non-commercial application. Robots are very special since, a robot can be change based on the requirement and it’s diligently obeying the order given by their masters. Secondly, the robot is induced to observe the real world and act upon and exhibit the task accurately to give perfect result at any moment. The feature of grasping the real world parameter to do a task in an iterative fashion leads to automated Robot. Generally, in thought a robot is moving object which react based on the feedback given to the system. Integrating the automatic and mobile behavior of a robot can be fulfilled only when the robot is capable of overcoming the obstacle and prove their maximum efficiency in find their absolute path towards destination. In this paper, we discuss about the sensor that help to feedback the system to detect obstacle and the actuator to avoid the obstacle.
