Weighted Fair Queue Scheduling Algorithm for IEEE802. 16 Wireless Networks

which is also known as IEEE 802.16 standards, supports lastmile broadband access wireless networks. WiMAX technology uses a number of scheduling techniques in the Medium Access Control layer, which is responsible for the utilization of available resources in the networks and distribute them among users in order to ensure the desired quality of service. In this work, the performance of Weighted Fair Queuing (WFQ) scheduling algorithm is evaluated to attain Quality of Service (QoS). The weight is assigned for a different service depends on the percentage of bandwidth utilization and priority of services. The proposed scheduling algorithm has designed and simulated using MatLab. The performance is evaluated with the other existing scheduling algorithm like First In First Out (FIFO), Priority queuing (PQ) and Weighted Round Robin (WRR).
Bayesian Reasoning Using 3D Relations for Lane Marker Detection

We introduce a lane marker detection algorithm that integrates 3D attributes as well as 3D relations between local edges and semi-global contours in a Bayesian framework. The algorithm is parameter free and does not make use of any heuristic assumptions. The reasoning is based on the complete conditional probabilities of the different cues which are estimated from a training set. The importance of the individual visual cues can be computed using a standard measure and the cues can then be combined in an optimal way. In addition we show that when doing 3D reasoning, the uncertainties connected to the reconstruction process need to be taken into account to make the reasoning process more stable. The results are shown on a publicly available data set.
Severe influenza treatment guideline

Background and purpose Severe influenza is defined as influenza with a severe symptom or syndrome such as respiratory distress or deceased consciousness or accompanying a severe complication such as encephalopathy or renal failure. In contrast to mild influenza, for which patients recover mostly by ambulatory care, severe influenza requires hospital admission in most cases or intensive treatment in the intensive care unit in some cases. In particular, the elderly, infants, and chronic patients are known to be at high risk for severe influenza because they may have accompanying complications such as exacerbation of an underlying disease, development of pneumonia, and another organ dysfunction or they may die. Therefore, there is an increasing need for an effective treatment method applicable to severe influenza. Severe influenza treatment methods, which have been recently discussed, include high-dose, long-term antiviral therapy, combination antiviral therapy, administration of antibiotics, application of extracorporeal membrane oxygenation (ECMO), administration of a corticosteroid, administration of intravenous immunoglobulin (IVIG), application of plasmapheresis, and administration of a statin. However, no comprehensive, specific expert guideline for these methods is available yet. The Transgovernmental Enterprise for Pandemic Influenza in Korea published in 2012 a guideline for the use of an antiviral agent for seasonal influenza. But the guideline deals with only the use of an antiviral agent, not the various treatment methods which can be applied to severe influenza [1]. Therefore, this guideline was developed by analyzing and evaluating domestic and international literature and guidelines with respect to the various treatment methods so that severe influenza could be effectively treated.
Changes in systemic vascular resistance detected by the arterial resistometer: preliminary report of a new method tested during percutaneous transluminal coronary angioplasty.

A recently developed apparatus provides on-line continuous monitoring of systemic vascular resistance (SVR) by means of simple computer analysis of the peripheral arterial waveform. The fundamental equation of this method is Ri = P'/(dP/dt), where dP/dt is the peak dP/dt of the peripheral arterial waveform, P' is the pressure at time of peak dP/dt, and Ri is a resistance index that bears a direct relation to SVR. Eleven patients undergoing percutaneous transluminal coronary angioplasty (PTCA) were studied to evaluate the changes in SVR associated with myocardial ischemia (angina detection). There were 49 balloon inflations, all of which were associated with an increase in Ri (from 38.4 +/- 12 to 81.2 +/- 36 X 10(-3) sec; p less than . 01) and a decrease in dP/dt (from 2076 +/- 257 to 1327 +/- 326 mm Hg/sec; p less than .01). In 42 of the balloon inflations these changes were associated with electrocardiographic ST-T changes and in 23 it was also associated with anginal pain. When angina was present, a further increase in Ri (to 97.5 +/- 43 X 10(-3) sec; p less than . 01) and a decrease in dP/dt (to 1218 +/- 338 mm Hg/sec; p less than .01) was observed. It was found that myocardial ischemia is associated with an increase in the resistance index and a decrease in dP/dt and can be detected by the resistometer.
Layered Task Allocation in Multi-robot Systems

A layered task allocation method is presented for multi-robot systems in a collaboration and adversarial, dynamic, real-time environment with unreliable communication in this paper. The process of task allocation is divided into three layers: task decomposition layer, task evaluation layer and task selection layer. In task decomposition layer, robots categorize their environments into corresponding modes, and fix subtasks in every mode as experts do, in order to reduce candidate tasks and decrease the complexity of task allocation. Q-Learning based on Adaptive Neuro Fuzzy Inference System (ANFIS) is adopted to compute utilities of candidate tasks in task evaluation layer. This can not only avoid the complicated opponent modeling but also make the learning more efficient. In task selection layer, task with the maximum utility is selected in application, but in learning, task is selected according to randomized Boltzmann exploration tactics in order to get more information for optimization. Simulation experiments implemented on simulated robotic soccer show that this approach improves performances of multi-robot systems greatly.
Soft Contact-based Rigid Object Manipulation : Planar Case

This paper focuses on the soft contact-based rigid object manipulation. First, a dynamic model of an object manipulation by two-fingered robot hand with soft fingertips is presented. In particular, we deal with a planar case to show certain valuable features in softfingertiped manipulation tasks. Next, in order to analyze the motion of using soft fingertips, a dynamic manipulation control scheme is employed. Finally, the influence of the dynamic deformation of soft fingertips applied in a rigid object manipulating task is demonstrated by several simulations.
When are sexual difficulties distressing for women? The selective protective value of intimate relationships.

INTRODUCTION Recent studies have shown that sexual functioning and sexually related personal distress are weakly related in women, with only a minority of sexual difficulties resulting in significant levels of distress. However, there has been little systematic research to date on which factors moderate the relationship between sexual functioning and sexual distress. AIM To assess the degree to which relational intimacy and attachment anxiety moderate the association between sexual functioning and sexual distress in college-age women. METHODS Two hundred women (mean age=20.25) completed surveys assessing sexual functioning, relational intimacy, attachment anxiety, and sexual distress. MAIN OUTCOME MEASURES Participants completed the Sexual Satisfaction Scale for Women, the Female Sexual Function Index, the Dimensions of Relationship Quality Scale, and the Revised Experiences in Close Relationships Measure of Adult Romantic Attachment. RESULTS Relational intimacy and attachment anxiety moderated the association between multiple aspects of sexual functioning and sexual distress. For lubrication and sexual pain, functioning was more strongly associated with distress in low-intimacy vs. high-intimacy relationships, but only for women with high levels of attachment anxiety. Results regarding desire were mixed and neither intimacy nor attachment anxiety interacted with subjective arousal or orgasm in predicting distress. CONCLUSION Both relational intimacy and attachment anxiety are important moderators of the association between sexual functioning and subjective sexual distress in women. Theoretical and practical implications are discussed.
Understanding the Factors That Influence Motivation and Experiences in High School Physical Education

In comparison to children, adolescents achieve significantly less physical activity (PA). Additionally, activity differences exist among genders and race/ethnicities. One means of influencing the PA habits of adolescents is high school physical education. Although PE class reaches students of all ages, genders, and races, motivation and experiences across these groups appear to differ. The purpose of this study was to determine if PE descriptors, motivators, and experiences in ninth- and 10th-grade students differed across gender, race/ethnicity, and grade. Ninth- and 10th-grade students (n = 698) completed a questionnaire about the factors that influence their motivation and experiences in PE class. Responses were compared across gender, race/ethnicity, and grade. Primary findings show that males and freshmen had more positive experiences in PE class than females and sophomores, respectively. Additionally, Caucasian students had more negative experiences in PE class in comparison to students of any other race/ethnicity. These findings illustrate the necessity for PE teacher sensitivity when they teach students of different genders, grades, and ethnic backgrounds. Special attention should be given to the social aspect of PE classes among females, student transition from middle school to high school, and the varying experiences in PE of students of different races/ethnicities. The results demonstrate the need for future research in this area.
Effect finishing and polishing procedures on the surface roughness of IPS Empress 2 ceramic

Abstract Objective. To evaluate the surface roughness of IPS Empress 2 ceramic when treated with different finishing/polishing protocols. Materials and methods. Sixteen specimens of IPS Empress 2 ceramic were made from wax patterns obtained using a stainless steel split mold. The specimens were glazed (Stage 0–S0, control) and divided into two groups. The specimens in Group 1 (G1) were finished/polished with a KG Sorensen diamond point (S1), followed by KG Sorensen siliconized points (S2) and final polishing with diamond polish paste (S3). In Group 2 (G2), the specimens were finished/polished using a Shofu diamond point (S1), as well as Shofu siliconized points (S2) and final polishing was performed using Porcelize paste (S3). After glazing (S0) and following each polishing procedure (S1, S2 or S3), the surface roughness was measured using TALYSURF Series 2. The average surface roughness results were analyzed using ANOVA followed by Tukey post-hoc tests (α = 0.01) Results. All of the polishing procedures yielded higher surface roughness values when compared to the control group (S0). S3 yielded lower surface roughness values when compared to S1 and S2. Conclusions. The proposed treatments negatively affected the surface roughness of the glazed IPS Empress 2 ceramic.

Broadcast in radio networks

We show that for any radio network there exists a schedule of a broadcast whose time is O(D + 1og5(n)), where D is the diameter and n is the number of nodes. (This result implies an optimal broadcast to networks with D = R(log5 n). ) We present a (centralized) polynomial time algorithm that given a network and a source, outputs a schedule for broadcasting the message from the source to the rest of the network.
Imaging cell biology in live animals: Ready for prime time

Time-lapse fluorescence microscopy is one of the main tools used to image subcellular structures in living cells. Yet for decades it has been applied primarily to in vitro model systems. Thanks to the most recent advancements in intravital microscopy, this approach has finally been extended to live rodents. This represents a major breakthrough that will provide unprecedented new opportunities to study mammalian cell biology in vivo and has already provided new insight in the fields of neurobiology, immunology, and cancer biology.

Soluble P-Selectin Levels Are Associated with Cardiovascular Mortality and Sudden Cardiac Death in Male Dialysis Patients

Background/Aims: P-selectin is released by activated platelets and endothelium contributing to inflammation and thrombosis. We evaluated the association between soluble P-selectin and atherosclerotic cardiovascular disease (ASCVD) in dialysis patients. Methods: We measured soluble P-selectin in serum from 824 incident dialysis patients. Using Cox proportional hazards models, we modeled the association of P-selectin levels with ASCVD events, cardiovascular mortality and sudden cardiac death. Results: After adjustment for demographics, comorbidity and traditional cardiovascular risk factors, higher P-selectin levels were associated with increased risk of ASCVD and cardiovascular mortality among males (p = 0.02 and p = 0.01, respectively), but not females (p = 0.52 and p = 0.31, respectively; p interaction = 0.003), over a median of 38.2 months. Higher P-selectin was associated with a greater risk of sudden cardiac death among males (p = 0.05). The associations between increasing P-selectin and cardiovascular mortality as well as sudden cardiac death in males persisted after adjustment for C-reactive protein, interleukin-6, serum albumin and platelet count (p = 0.01 and p = 0.03, respectively). The risk for sudden cardiac death was more than 3 times greater for males in the highest tertile of soluble P-selectin compared with the lowest tertile after adjustment (HR: 3.19; 95% CI: 1.18 – 8.62; p = 0.02). Conclusion: P-selectin is associated with ASCVD, cardiovascular mortality and sudden cardiac death among male dialysis patients.
Ant System-Corner Insertion Sequence: An Efficient VLSI Hard Module Placer

Abstract Placement is important in VLSI physical design as it determines the time-to-market and chips reliability. In this paper, a new floorplan representation which couples with Ant System, namely Corner Insertion Sequence (CIS) is proposed. Though CISs search complexity is smaller than the state-of-the-art representation Corner Sequence (CS), CIS adopts a preset boundary on the placement and hence, leading to search bound similar to CS. This enables the previous unutilized corner edges to become viable. Also, the redundancy of CS representation is eliminated in CIS leads to a lower search complexity of CIS. Experimental results on Microelectronics Center of North Carolina (MCNC) hard block benchmark circuits show that the proposed algorithm performs comparably in terms of area yet at least two times faster than CS. Index TermsDesign, system, aided, floorplanning, VLSI, representation, circuits, algorithm, scale, optimization. I. I NTRODUCTION In the modern IC design flow, a placement of an IC is a schematic representation of placement of its major functional blocks. As the Very Large Scale Integration (VLSI) chip keeps shrinking in size, many factors such as the total area [1-2], wirelength [3-5], power consumption [6-7] and congestion reduction [8-9] will affect the reliability and efficiency of the chip. Hence, to cope up with these issues, efficient placement plays a very crucial role as far as the quality of the VLSI design is concerned. The VLSI placement design problem is well-known as the NP-hard problem and hence it is difficult to find exactly optimal solution in practical applications [10-11]. In order to solve this combinatorial optimization problem, placement layout is tackled mathematically in order to be optimized using the tools such as mathematical optimization or artificial intelligence (AI) technique. Many approaches [1], have been proposed in the literature with different modeling representations [12-15] and optimization methods [2], [5], [16-17] to enhance the quality of the placement design. To facilitate a good placement, it is necessary to develop an effective model for blocks placement to reduce the dead space area as well as minimizing the placement runtime. II. P
High-Redshift X-Ray-Selected Quasars: CXOCY J125304.0−090737 Joins the Club

We present a new X-ray–selected high-redshift quasar CXOCY J125304.0-090737 at z = 4.179, discovered by the Calán-Yale Deep Extragalactic Research (CYDER) Survey. This quasar is the fifth X-ray–selected high-redshift radio-quiet quasar (z > 4) found so far. Here we present its observed properties, which are characterized by its relative optical and X-ray faintness, its X-ray hardness, and its X-ray strength compared with optically selected quasars at high redshift. We also compare the X-ray–selected high-redshift radio-quiet quasars with their optically selected counterparts. We find that the optical to X-ray spectral slope, αox, is statistically harder (more X-ray luminous) for the X-ray–selected radio-quiet quasars than for the optically selected ones. This result, given the different range of rest frame ultraviolet luminosities studied and the selection of the samples, is consistent with the previously found correlation between X-ray and rest-frame ultraviolet luminosities and would extend that result to a much wider luminosity range at high redshift. Finally, we discuss the prospects of unveiling the quasar luminosity function at high redshifts using X-ray surveys. The discovery of a high-redshift object in the first field of our survey program provides suggestive evidence that X-ray–selected surveys may identify more such objects than would be expected from an extrapolation of the optical luminosity function.
Growing semantically meaningful models for visual SLAM

Though modern Visual Simultaneous Localisation and Mapping (vSLAM) systems are capable of localising robustly and efficiently even in the case of a monocular camera, the maps produced are typically sparse point–clouds that are difficult to interpret and of little use for higher–level reasoning tasks such as scene understanding or human– machine interaction. In this paper we begin to address this deficiency, presenting progress on expanding the competency of visual SLAM systems to build richer maps. Specifically, we concentrate on modelling indoor scenes using semantically meaningful surfaces and accompanying labels, such as “floor”, “wall”, and “ceiling” — an important step towards a representation that can support higher-level reasoning and planning. We leverage the Manhattan world assumption and show how to extract vanishing directions jointly across a video stream. We then propose a guided line detector that utilises known vanishing points to extract extremely subtle axis– aligned edges. We utilise recent advances in single view structure recovery to building geometric scene models and demonstrate our system operating on–line.
Time-aware test-case prioritization using integer linear programming

Techniques for test-case prioritization re-order test cases to increase their rate of fault detection. When there is a fixed time budget that does not allow the execution of all the test cases, time-aware techniques for test-case prioritization may achieve a better rate of fault detection than traditional techniques for test-case prioritization. In this paper, we propose a novel approach to time-aware test-case prioritization using integer linear programming. To evaluate our approach, we performed experiments on two subject programs involving four techniques for our approach, two techniques for an approach to time-aware test-case prioritization based on genetic algorithms, and four traditional techniques for test-case prioritization. The empirical results indicate that two of our techniques outperform all the other techniques for the two subjects under the scenarios of both general and version-specific prioritization. The empirical results also indicate that some traditional techniques with lower analysis time cost for test-case prioritization may still perform competitively when the time budget is not quite tight.
Building a Semantic-Web Portal Using Frame-based System ∗

In this paper we report employing frame-based system as the basis to build up a ontology-based portal. The basic idea is to transform the ontology schema and instances collected from various digital library sites using the semantics of the frame-based system. The service programs written using the frame-based reasoning formalism thus can make use the knowledge.
M(atrix)-Theory Scattering in the Noncommutative (2,0) theory

We study the Quantum-Mechanics on the hyper-Kahler manifold that is the blow-up of an $A_1$-singularity. This system is relevant for M(atrix)-theory as it was conjectured to describe scattering in the "noncommutative" deformation of a free 5+1D tensor multiplet in the sector with two units of longitudinal light-like momentum.
