Improving the Performance of VANETs using Many-to-Many Communication

Vehicular Ad-hoc Networks (VANETs) have emerged as an area with large number of applications and have gained the attention of the research community. The performance of a VANET largely depends on its properties such as vehicle speed, density, mobility model, and routing scheme used. Use of CSMA as medium access control technique brings many challenges in the overall performance of VANETs. In case of city scenarios where high vehicle density is expected, due to CSMA, a large amount of contention is faced during communication. This eventually has an adverse effect on the delay performance of the network. Many-to-many communication enables simultaneous multi-packet transmission and reception of information between vehicles. In this paper, we for the first time investigate the use of many-to-many communication in VANETs. It is observed through analysis and simulations that use of many-to-many communication for all types of VANET applications gives better performance than CSMA-based VANETs in terms of average end-to-end delay and average packet delivery ratio. We also provide a detailed analysis of the average packet delivery ratio and the average end-to-end delay by modelling the buffers at vehicles and road side units as M/M/1 and M/D/1 queues, respectively. Our analytical results are in good agreement with simulation results.
On the Cross Section of Conditionally Expected Stock Returns

In this paper, we use macrovariables advocated by recent authors to make out-of-sample forecast for returns on individual stocks and then sort stocks equally into ten portfolios on this proxy of conditionally expected returns. The average returns increase monotonically from the first decile (stocks with the lowest expected returns) to the tenth decile (stocks with the highest expected returns), and the difference between the tenth and first deciles is a significant 4.8 percent per year. While these portfolios pose a challenge to the CAPM, they appear to be explained by Carhart's (1997) four-factor model. Our results indicate that the CAPM anomalies might not be attributed entirely to data snooping or irrational pricing because they are correlated with systematic movements of the macrovariables that forecast stock market returns.
Cellular automata models of single-lane traffic

The jamming transition in the stochastic cellular automation model (Nagel-Schreckenberg model [J. Phys. (France) I 2, 2221 (1992)]) of highway traffic is analyzed in detail by studying the relaxation time, a mapping to surface growth problems, and the investigation of correlation functions. Three different classes of behavior can be distinguished depending on the speed limit ${v}_{\mathrm{max}}. $ For ${v}_{\mathrm{max}}=1$ the model is closely related to the Kardar-Parisi-Zhang class of surface growth. For $1l{v}_{\mathrm{max}}l\ensuremath{\infty}$ the relaxation time has a well-defined peak at a density of cars \ensuremath{\rho} somewhat lower than the position of the maximum in the fundamental diagram: This density can be identified with the jamming point. At the jamming point the properties of the correlations also change significantly. In the ${v}_{\mathrm{max}}=\ensuremath{\infty}$ limit the model undergoes a first-order transition at $\ensuremath{\rho}\ensuremath{\rightarrow}0. $ It seems that in the relevant cases $1l{v}_{\mathrm{max}}l\ensuremath{\infty}$ the jamming transition is under the influence of a second-order phase transition in the deterministic model and a first-order transition for ${v}_{\mathrm{max}}=\ensuremath{\infty}. $
A Cross-Linguistic Study of Persuasive Strategies used in Persian and English Languages

The present study aimed to recast the issue of production of speech act of persuasion in English and Persian languages. This study first attempts to analyze the types of persuasive strategies used in English and Persian. To this end, 184 Persian speakers and native speakers of English participated in this study. The participants of this study were all university students. The data was collected by means of a discourse completion test (DCT). The questionnaire consists of 6 items in different contexts close to real life persuasive situations. Chi-square test was used to analyze the data. The participants’ responses were analyzed and the influences of gender and culture on the speech act of persuasion were discussed. Results indicate some differences and similarities between Persian and English native speakers in employment of this speech act which provide some pedagogical solution to pragmatic difficulties of English language learners in classrooms and their miscommunications in general.
The relationship between school counselor leadership practices and comprehensive program implementation

THE RELATIONSHIP BETWEEN SCHOOL COUNSELOR LEADERSHIP PRACTICES AND COMPREHENSIVE PROGRAM IMPLEMENTATION by Erin Chase McCarty Mason Reform initiatives in education since the introduction of No Child Left Behind (NCLB) call for all educators to develop strategies to increase student achievement and improve school climate. School counselors are charged by their professional organizations to act as agents of change in their schools and to demonstrate the effectiveness of their programs. To garner support for school counseling programs that cultivate positive results for students and schools, school counselors need to adopt a leadership mindset. The purpose of this exploratory study was to assess leadership practices of school counselors, and to analyze the relationships between demographics, experience, training, work setting, school counseling program implementation and leadership practices. This study addresses the need for understanding the way school counselor leadership promotes school counseling programs that contribute to positive student outcomes. Participants in this study were recruited through convenience sampling from a state school counseling association and completed a research packet including a demographic survey and two instruments, The Leadership Practices Inventory (LPI), Self Instrument, 3 rd edition by Kouzes and Posner (2003) and The School Counseling Program Implementation Scale (SCPIS) by Carey & Elsner (2006). Correlation analyses were used to describe relationships of demographic, training and work setting variables with leadership practices and program implementation. Analysis of variance examined mean differences and regression analyses assessed predictive qualities of identified relationships between the independent and dependent variables. Variables of age, experience, preparation and school setting were correlated with leadership practices and program implementation. Age, experience, size of school population and professional licensure predicted leadership practices of school counselors. Experience predicted comprehensive program implementation. Results revealed statistically significant positive relationships between school counselor leadership practices and comprehensive program implementation. Model the Way (MTW) and Enable Others to Act (EOA) leadership practices predicted the level of school counseling program implementation.

Linear equalizer based in NLMS algorithms for a communication system with integrated power transmission

In this paper is shown a communication system, specifically designed for integrated power transmission, what means the integration in the same power line, both the power supply and the data. This communication media is characterized by its unpredicted behavior, a drawback. The different elements of this system and the modulation used are defined and studied, outstanding mainly the channel equalization process to overcome this drawback. The channel equalization process is based on a linear filtering with adaptive algorithms, like the Normalized Least-Mean Squared (NLMS) algorithm. The intention of this paper is to improve these adaptive algorithms in order to get a faster channel equalization, using for this, variations based on Affine Projection Algortihms (APA). This article presents a new algorithm for the channel equalisation that is based on the non-decimated filter-bank transform.

Functional Cooperation of β1-Integrins and Members of the Ig Superfamily in Neurite Outgrowth Induction

Neurite outgrowth is a central aspect of the ontogenetic formation of neural networks and is regulated by distinct groups of cell surface molecules. One protein involved in neurite elongation and fasciculation is the neural Ig superfamily member F11/contactin. We have shown previously that F11 promotes neurite extension of chick tectal neurons by interaction with the tectal receptor NrCAM, a member of the L1 subgroup of the Ig superfamily. By contrast, it does not induce outgrowth of retinal neurons despite the fact that these cells also express NrCAM, suggesting that in retinal cells the F11–NrCAM interaction alone is not sufficient to induce neurite extension. In this report we present a novel image analysis procedure to quantify neurite outgrowth and use it to demonstrate that F11 enhances the fibronectin-induced outgrowth response of embryonic retinal neurons. We reveal that NrCAM is the neuronal receptor mediating the enhanced outgrowth of retinal neurons, whereas the related F11-binding molecule NgCAM is not involved. Furthermore, we provide evidence that a β1-integrin may represent the fibronectin-dependent receptor that cooperates indirectly with the F11–NrCAM pathway. Our results support the concept of a combinatorial labeling of cells in nervous system histogenesis by different classes of cell surface proteins, in particular by integrins and molecules of the Ig superfamily.
LEADERSHIP AND INNOVATION: CHAMPIONS AND TECHIES AS AGENTS OF INFLUENCE

The effects of innovation on leadership abilities have not been widely investigated. Although diffusion of innovation theory has existed for some time, there is a need for other perspectives. In two (N=238, N=294) related studies it was found that innovation, leadership, and influence were related, though specific relationship indicated tendencies toward certain styles of influence. Innovation was significantly related to transformational leadership abilities. Implications emerging from the relationship between transformational leadership and innovation are discussed, including the distinction between the champion and "techie" styles of innovation and their basis in leadership activity Leadership and Innovation 3
Family history of venous thromboembolism as a risk factor and genetic research tool

Summary Familial clustering of venous thromboembolism (VTE) was described as far back as 1905 by Briggs. Although Egeberg discovered inherited deficiency of antithrombin in 1965, it was not until Dahlback discovered resistance to activated protein C in 1993 that it became clear that genetic factors are common risk factors of VTE. Several genes have been linked to familial aggregation of VTE and genome-wide association studies have found several novel gene loci. Still, it has been estimated that much of the heritability for VTE remains to be discovered. Family history (FH) of VTE is therefore still important to determine whether a patient has an increased genetic risk of VTE. FH has the potential to represent the sum of effects and interactions between environmental and genetic factors. In this article the design, methodology, results, clinical and genetic implications of FH studies of VTE are reviewed. FH in first-degree relatives (siblings and/or parents) is associated with a 2–3 times increased familial relative risk (FRR). However, the FRR is dependent on age, number of affected relatives, and presentation of VTE (provoked/unprovoked). Especially high familial risks are observed in individuals with two or more affected siblings (FFR> 50). However, the familial risk for recurrent VTE is much lower or non-significant. Moreover, FH of VTE appears mainly to be important for venous diseases (i. e. VTE and varicose veins). The familial associations with other diseases are weaker. In conclusion, FH of VTE is an important research tool and a clinically potential useful risk factor for VTE.
RATIONAL RESPONSES TO HIGH-STAKES TESTING AND THE SPECIAL CASE OF NARROWING THE CURRICULUM

, indicating that art, music, government, rhetoric, philosophy and the like, are the arts of free men and woman. Benjamin Barber (1994) contrasted the liberal arts against what were called the servile arts: business and law enforcement, food preparation and medicine, mechanics and technology. The servile arts encompass the knowledge and skills needed to run the country. This was exactly what the Greeks wanted their slaves and servants to do while they engaged in the kind of grand political and philosophical thinking that gave the Western world its intellectual heritage. America being a practical country, a land for the promotion of Yankee ingenuity and dominated by the interests of business, never was in awe of the liberal arts or the humanities. There
Collecting a Large-scale Dataset of Fine-grained Cars

In this work we introduce a large-scale, fine-grained dataset of cars. This dataset, consisting of 197 classes and 16,185 images, represents an order of magnitude increase in size over the only existing fine-grained car dataset [7] (14 classes, 1,904 images) and is comparable in size to the largest fine-grained datasets publicly available [9, 3]. The goals of this work are twofold: 1) to describe the difficulties encountered when collecting such a dataset and 2) to present baseline performance for two state-of-the-art methods.

Superposition Coding-Based Bounds and Capacity for the Cognitive Z-Interference Channels

This paper considers the cognitive interference channel (CIC) with two transmitters and two receivers, in which the cognitive transmitter non-causally knows the message and codeword of the primary transmitter. We first introduce a discrete memoryless more capable CIC, which is an extension to the more capable broadcast channel (BC). Using superposition coding, we propose an inner bound and an outer bound on its capacity region. The outer bound is also valid when the primary user is under strong interference. For the Gaussian CIC, this outer bound applies for $|a| \geq 1 $, where $a$ is the gain of interference link from secondary user to primary receiver. These capacity inner and outer bounds are then applied to the Gaussian cognitive Z-interference channel (GCZIC) where only the primary receiver suffers interference. Upon showing that jointly Gaussian input maximizes these bounds for the GCZIC, we evaluate the bounds for this channel. The new outer bound is strictly tighter than other outer bounds on the capacity of the GCZIC at strong interference ($a^2 \geq 1 $). Especially, the outer bound coincides with the inner bound for $|a| \geq \sqrt{1 + P_1}$ and thus, establishes the capacity of the GCZIC at this range. For such a large $a$, superposition encoding at the cognitive transmitter and successive decoding at the primary receiver are capacity-achieving.
Radar-based fall detection based on Doppler time-frequency signatures for assisted living

Falls are a major public health concern and main causes of accidental death in the senior U.S. population. Timely and accurate detection permit immediate assistance after a fall and, thereby, reduces complications of fall risk. Radar technology provides an effective means for this purpose because it is non-invasive, insensitive to lighting conditions as well as obstructions, and has less privacy concerns. In this study, the authors develop an effective fall detection scheme for the application in continuous-wave radar systems. The proposed scheme exploits time-frequency characteristics of the radar Doppler signatures, and the motion events are classified using the joint statistics of three different features, including the extreme frequency, extreme frequency ratio, and the length of event period. Sparse Bayesian classifier based on the relevance vector machine is used to perform the classification. Laboratory experiments are performed to collect radar data corresponding to different motion patterns to verify the effectiveness of the proposed algorithm. Language: en
Complexities in Adjustment Patterns among the “Best and the Brightest”: Risk and Resilience in the Context of High Achieving Schools

Youth in high achieving schools (HAS) are at elevated risk for serious adjustment problems—including internalizing and externalizing symptoms and substance use—given unrelenting pressures to be “the best. ” For resilience researchers, successful risk evasion in these high-pressure settings should, arguably, be defined in terms of the absence of serious symptoms plus behaviorally manifested integrity and altruism. Future interventions should target that which is the fundamental basis of resilience: Dependable, supportive relationships in everyday settings. These must be promoted between adults and children and among them, toward enhancing positive development among youth and families in these high stress environments.
Hydrological connectivity of soil pipes determined by ground‐penetrating radar tracer detection

Soil pipes are common and important features of many catchments, particularly in semi‐arid and humid areas, and can contribute a large proportion of runoff to river systems. They may also signiﬁcantly inﬂuence catchment sediment and solute yield. However, there are often problems in ﬁnding and deﬁning soil pipe networks which are located deep below the surface. Ground‐penetrating radar (GPR) has been used for non‐destructive identiﬁcation and mapping of soil pipes in blanket peat catchments. While GPR can identify subsurface cavities, it cannot alone determine hydrological connectivity between one cavity and another. This paper presents results from an experiment to test the ability of GPR to establish hydrological connectivity between pipes through use of a tracer solution. Sodium chloride was injected into pipe cavities previously detected by the radar. The GPR was placed downslope of the injection points and positioned on the ground directly above detected soil pipes. The resultant radargrams showed signiﬁcant changes in reﬂectance from some cavities and no change from others. Pipe waters were sampled in order to check the radar results. Changes in electrical conductivity of the pipe water could be detected by the GPR, without data post‐processing, when background levels were increased by more than approximately twofold. It was thus possible to rapidly determine hydrological connectivity of soil pipes within dense pipe networks across hillslopes without ground disturbance. It was also possible to remotely measure travel times through pipe systems; the passing of the salt wave below the GPR produced an easily detectable signal on the radargram which required no post‐processing. The technique should allow remote sensing of water sources and sinks for soil pipes below the surface. The improved understanding of ﬂowpath connectivity will be important for understanding water delivery, solutional and particulate denudation, and hydrological and geomorphological model development.

Vaccinia Virus Inhibitors as a Paradigm for the Chemotherapy of Poxvirus Infections

SUMMARY Poxviruses continue to pose a major threat to human health. Monkeypox is endemic in central Africa, and the discontinuation of the vaccination (with vaccinia virus) has rendered most humans vulnerable to variola virus, the etiologic agent of smallpox, should this virus be used in biological warfare or terrorism. However, a large variety of compounds have been described that are potent inhibitors of vaccinia virus replication and could be expected to be active against other poxviruses as well. These compounds could be grouped in different classes: (i) IMP dehydrogenase inhibitors (e.g., EICAR); (ii) SAH hydrolase inhibitors (e.g., 5′-noraristeromycin, 3-deazaneplanocin A, and various neplanocin A derivatives); (iii) OMP decarboxylase inhibitors (e.g., pyrazofurin) and CTP synthetase inhibitors (e.g., cyclopentenyl cytosine); (iv) thymidylate synthase inhibitors (e.g., 5-substituted 2′-deoxyuridines); (v) nucleoside analogues that are targeted at viral DNA synthesis (e.g., Ara-A); (vi) acyclic nucleoside phosphonates [e.g., (S)-HPMPA and (S)-HPMPC (cidofovir)]; and (vii) polyanionic substances (e.g., polyacrylic acid). All these compounds could be considered potential candidate drugs for the therapy and prophylaxis of poxvirus infections at large. Some of these compounds, in particular polyacrylic acid and cidofovir, were found to generate, on single-dose administration, a long-lasting protective efficacy against vaccinia virus infection in vivo. Cidofovir, which has been approved for the treatment of cytomegalovirus retinitis in immunocompromised patients, was also found to protect mice, again when given as a single dose, against a lethal aerosolized or intranasal cowpox virus challenge. In a biological warfare scenario, it would be advantageous to be able to use a single treatment for an individual exposed to an aerosolized poxvirus. Cidofovir thus holds great promise for treating human smallpox, monkeypox, and other poxvirus infections. Anecdotal experience points to the efficacy of cidofovir in the treatment of the poxvirus infections molluscum contagiosum and orf (ecthyma contagiosum) in immunosuppressed patients.
orsions for Manifolds with Boundary and Glueing Formulas

We extend the definition of analytic and Reidemeister torsion for closed compact iemannian manifolds, to compact Riemannian manifolds with boundary (M, δ M), given a parallel at bundle F of A‐Hilbert modules of finite type and a decomposition of the boundary δM = ‐M ⊔ δ+M into disjoint components. When F is induced from the universal covering of M, and the fundamental group of M is infinite (cf. [BFKM]), these torsions are known as the L2‐analytic resp. 2‐Reidemeister torsions. If the system (M, δ‐M, δ+M, F) is of determinant class we compute he quotient of the analytic and the Reidemeister torsion and prove gluing formulas for both of hem. In particular we answer positively Conjecture 7.6 in [LL]. If F is induced from a Γ‐principal overing where Γ is a residually finite group, we derive from work of Lück (cf. [L3]), that the system (M, δ‐M, δ+M, F) is of determinant class (cf. Theorem 5.1 in Appendix A).
Simple, Sensitive, and Swift Sequencing of Complete H5N1 Avian Influenza Virus Genomes

The spread of highly pathogenic avian influenza A virus (HPAIV) of subtype H5N1 demands fast and reliable methods for in-depth, full-length sequence analysis. For this purpose, we designed a simple and sensitive method for the preparation of sequencing libraries from H5N1 HPAIV diagnostic RNA samples for sequencing with the Genome Sequencer FLX instrument. The method presented seamlessly integrates high-throughput pyrosequencing with the Roche/454 instrument into diagnostics without the need for additional equipment or molecular biological techniques besides standard PCR and the Genome Sequencer FLX sample preparation and sequencing pipeline.
