Fast Rendering of Diffusion Curves with Triangles

Diffusion curves are a new kind of primitive in vector graphics, capable of representing smooth color transitions among boundaries. Their rendering requires solving Poisson's equation; much previous research relied on traditional solvers, which commonly require GPU acceleration to achieve real-time rasterization. This obviously restricts deployment on the Internet&amp;amp;#x2014;for example, as rich Internet applications, in which various computing environments are involved. Diffusion effects are similar to locally defined interpolation with a particular orientation and magnitude. Inspired by that observation, a mesh-based framework combined with mean value coordinates (MVC) interpolants efficiently renders diffusion curve images on a CPU. This method employs a visibility algorithm to efficiently find and sort neighboring curve nodes for each vertex. It then assigns the vertex colors according to MVC interpolation with the neighboring curve nodes. Experiments produced rendering results comparable to traditional solvers, but this method is computationally more efficient and runs much faster on a CPU.
A pr 2 00 7 ANNIHILATORS OF LOCAL COHOMOLOGY IN CHARACTERISTIC ZERO

This paper discusses the problem of whether it is possible to annihilate elements of local cohomology modules by elements of arbitrarily small order under a fixed valuation. We first discuss the general problem and its relationship to the Direct Summand Conjecture, and next present two concrete examples where annihilators with small order are shown to exist. We then prove a more general theorem, where the existence of such annihilators is established in some cases using results on abelian varieties and the Albanese map. 1. Almost vanishing of local cohomology The concept of almost vanishing that we use here comes out of recent work on Almost Ring Theory by Gabber and Ramero [4]. This theory was developed to give a firm foundation to the results of Faltings on Almostétale extensions [3], and these ideas have their origins in a classic work of Tate on p-divisible groups [21]. The use of the general theory, for our purposes, is comparatively straightforward, but it illustrates the main questions in looking at certain homological conjectures, as discussed later in the section. The approach is heavily influenced by Heitmann's proof of the Direct Summand Conjecture for rings of dimension three [8]. Let A be an integral domain, and let v be a valuation on A with values in the abelian group of rational numbers; more precisely, v is a function from A to Q ∪ {∞} such that (1) v(a) = ∞ if and only if a = 0, (2) v(ab) = v(a) + v(b) for all a, b ∈ A, and (3) v(a + b) min{v(a), v(b)} for all a, b ∈ A. We will also assume that v(a) 0 for all elements a ∈ A.
Leveraging Process Evaluation for Project Development and Sustainability: The Case of the CAMPUS Asia Program in Korea

CAMPUS Asia (Collective Action for Mobility Program of University Students in Asia) is a student-exchange program designed to promote student mobility between South Korea, China, and Japan. Begun in 2011, the program aims to foster the next generation of leaders in Asia by nurturing young talents with shared visions. This article provides an overview of the CAMPUS Asia pilot program and the major findings of its comprehensive process evaluation in Korea using five criteria. The evaluation indicates that the CAMPUS Asia program has evolved into a unique program that promotes dual degrees, creates new learning models, and develops in-depth discussions of substantial collaborations among consortia. The need to develop mechanisms for applying the lessons learned and insights gained through the evaluation is addressed; implications and recommendations for sustainable development of the CAMPUS Asia pilot program are offered, as are the benefits of implementing a process evaluation in one’s own practice.
Contributing factors to poor functional recovery after delayed nerve repair: prolonged axotomy

The contribution of prolonged motoneuron axotomy to the poor functional recovery after delayed nerve repair was determined by means of a nerve cross-anastomosis paradigm in the rat. The tibial nerve was axotomized up to 12 months before it was cross-sutured to the distal stump of the freshly cut common peroneal nerve to innervate the freshly denervated tibialis anterior muscle. Three to 17 months later, muscle and motor unit (MU) forces were measured to quantify the number of axons that had successfully regenerated and reinnervated the muscle. The extent of axonal branching was estimated by the innervation ratio (IR) (i.e., the number of muscle fibers innervated by each axon), which was obtained directly by counting muscle fibers in a single glycogen-depleted MU in each muscle and indirectly by calculation. The total number of MUs in each muscle significantly decreased with progression of axotomy and was only 35% of the control when axotomy was prolonged more than 3 months. Concurrently, MU force and IR increased exponentially, with a mean increase of threefold when axotomy was more than 3 months, which largely compensated for the reduction in the number of axons that reinnervated the muscle. Consequently, muscles reinnervated by tibial motor axons that had been axotomized up to 12 months produced as much force as those reinnervated by freshly axotomized tibial motor axons. Muscle weight, size, and muscle fiber size were similar to those after immediate nerve suture. Although prolonged axotomy does not compromise the number of muscle fibers innervated by each axon, it does reduce the capacity of motor axons to regenerate and thus is an important contributing factor to the poor functional recovery in delayed nerve repair.
Effect of Fractional Kinetic Helicity on Turbulent Magnetic Dynamo Spectra

Magnetic field amplification in astrophysics ultimately requires an understanding of MHD turbulence. Kinetic helicity has long been known to be important for large-scale field growth in forced MHD turbulence and has been recently demonstrated numerically to be asymptotically consistent with slow mean field dynamo action in a periodic box. Here we show numerically that the magnetic spectrum at and below the forcing scale is also strongly influenced by kinetic helicity. We identify a critical value, fh, crit, above which the magnetic spectrum develops maxima at a wavenumber of 1 scale and at the forcing scale. For f < fh, crit. the field peaks only at the resistive scale. Kinetic helicity may thus be important not only for generating a large-scale field, but also for establishing observed peaks in magnetic spectra at the forcing scale. The turbulent Galactic disk provides an example where both large-scale (greater than the supernova forcing scale) fields and small-scale (less than or equal to forcing scale, with peak at forcing scale) fields are observed. We discuss this and the potential application to the protogalaxy, but we also emphasize the limitations in applying our results to these systems.
AN INTERACTION MODEL DESIGNED FOR HAND GESTURE INPUT

This paper describes an interaction model that allows a user to interact with a computer system through gestures while using gestures at the same time for interaction in the real world. This model uses simple rules for detecting the user's intention to address a gestural command to the system. Some rules are embedded in the model, while others are part of a set of guidelines for designing gestural command sets. Using this model, we have designed an application that allows a user to give a lecture by navigating through a set of slides with gestural commands. From the results of a usability testing of this application, we present other potential applications and directions for future work. This research aims at providing usable applications of hand gesture input in the real world. The results presented in this paper are of interest to researchers working on new interaction techniques based on gestures as well as designers of actual systems.

Executive Functioning as a Predictor of Hazard Perception Ability in Older Adults

MCINERNEY, KATALINA FERNANDEZ, M.A., August 2015, Psychology Executive Functioning as a Predictor of Hazard Perception Ability in Older Adults Director of Dissertation: Julie A. Suhr Hazard perception is the ability to detect and react to dangerous situations on the road, with reported strong associations with crash involvement (Horswill & McKenna, 2004). The present study investigated the neurocognitive correlates of hazard perception in a population of older adults without dementia. The final sample consisted of 22 males and 42 females between the ages of 60 and 88, X=70.36 (SD=6.88). Participants were screened for dementia using the RBANS. They were also administered a series of neuropsychological measures as well as a Hazard Perception Test (HPT). Better reaction time to touching the target hazards on the HPT was correlated with better performance on Trail Making Test Part B, r = . 28, p = . 012, Inhibition, r = . 22, p = . 041 and Switching, r = . 23, p = . 033 subtests of the Color-Word Interference Test and Useful Field of View part III, r = . 28, p = . 011. A lower number of errors on the HPT was associated with worse performance on Line Orientation, r =. 22, p = . 042, Block Design subtest, r = -. 36, p = . 002, Trail Making Test Part B, r = . 34, p = . 003, and Useful Field of View parts II, r = . 25, p = . 022 and III, r = . 28, p = . 012. Findings provide preliminary evidence of a relationship between visuospatial/constructional skills, executive functioning and hazard perception in healthy aging older adults. The present study adds to the limited literature on hazard perception in this population and helps guide future research.
Verification of Security Policies in Decentralized Management of Collaboration Systems

In this paper, we present a methodology for administrative policy specification in distributed management of collaboration systems. The goal of the methodology is to ensure that sensitive security requirements cannot be violated by untrusted participants. A model of administrative roles for distributed management of collaboration systems is presented. Model checking based on finite-state techniques is used to verify that global security requirements cannot be violated by untrusted users managing policies in a decentralized management. Several verification models are developed based on possible types of violation of administrative privileges – such as role admission policies, coordination policies, and object access policies.
Neuropsychological Functioning After Traumatic Injury to The Orbito-Frontal Area: A Polish Phineas Gage

The patient (PG, age 27, owner/operator of a construction company) suffered a severe head injury after a fall from scaffolding at a construction site. Two wooden pegs were broken off and driven deep-into his cranium, from left to right. However, the patient not only survived the injury, he did not even lose consciousness after the accident. The damage to the brain affected primarily the frontal lobes. The upper peg penetrated the right frontal lobe. In the years that followed neurosurgery, we observed a pattern of behavioral disorders consistent with frontal lobe syndrome, similar to the famous 19-century case of Phineas Gage. These symptoms make it impossible for the patient to adapt to social and cultural life. The purpose of our research was to describe the profile of negative and positive behavioral disturbances in PG, and to determine whether these behaviors developed over time into orbitofrontal syndrome. Microgenetic theory is used to interpret the formation of the symptom.
Use fast R-CNN and cascade structure for face detection

Face detection is challenging in real-world due to various poses, occlusions, lighting conditions and so on. Recently, deep learning achieves excellent performance on this task. In this paper, we propose a novel deep cascade convolutional network that uses Fast Region-based Convolutional Network (Fast R-CNN) [3] at the end of the structure. Our method achieves outstanding performance on the FDDB [1] and AFW [2] datasets. Especially, it achieves a high recall of 91.87% on the challenging FDDB benchmark, outperforming the state-of-the-art methods. We adopt a cascaded structure to quickly reject the background regions first. At the last stage, we choose Fast R-CNN to deal with the challenging candidates and it performs well.
3G-WLAN Convergence: Vulnerability, Attacks Possibilities and Security Model

In this paper we present the vulnerability, threats and attacks for third generation (3G) networks converged with WLAN and propose the security model addressing the roaming and non-roaming security scenarios. Many threats against 3G network resources can be realised by attacking the WLAN access network, therefore it is important to identify the security requirements for 3G-WLAN interworking and choose a security solution that is robust and dynamic to different levels of WLAN access network. The proposed architecture is based on the extensible authentication protocol (EAP) for USIM authentication & key agreement (AKA) and authorization procedures, and secure tunnel establishment using IKEv2 (Internet key exchange) protocol to minimize security threats. We will also discuss the termination of fake or forge WLAN session to protect the user confidential information on vulnerable wireless link. The development is part of secure service provisioning (SSP) framework of IP multimedia system (IMS) at 3Gb Testbed of Fokus Fraunhofer

Subclinical coronary atherosclerosis identified by coronary computed tomographic angiography in asymptomatic morbidly obese patients

Obesity is a common public health problem and obese individuals in particular have a disproportionate incidence of acute coronary events. This study was undertaken to identify coronary artery lesions as well as associated clinical features, risk factors and demographics in patients with a body mass index (BMI) >40 kg/m2 without known coronary artery disease (CAD). Morbidly obese subjects were prospectively recruited to undergo coronary computed tomographic angiography (CCTA) using a dual-source computed tomography (CT) system. CAD was defined as the presence of any atherosclerotic lesion in any one coronary artery segment. The presence, location, and severity of atherosclerosis were related to patient characteristics. Forty-one patients (28 women, mean age, 50.4±10.0 years, mean BMI, 43.8±4.8 kg/m2) served as the study population. Of these, 25 patients (61%) had at least one coronary stenosis. All but 2 patients within the CAD cohort had coronary artery calcium (CAC) scores >0, and most plaques identified (75.4%) were non-calcified. There was a predilection of calcified and non-calcified atherosclerosis involving the left anterior descending (LAD) coronary artery compared with other coronary segments. Univariate predictors of CAD included older age, dyslipidemia, and diabetes. In this preliminary study of young morbidly obese patients, CCTA detected a high prevalence of calcified and non-calcified CAD, although the later predominated.
Executive functioning in children's reading comprehension development

The simple view of reading restricts itself to decoding and linguistic comprehension and does not consider the role of executive functions, which may additionally account for variation in children’s reading comprehension. The present study on reading comprehension therefore investigated the effects of multiple executive functions (i.e. working memory, inhibition and planning) to the components of the simple view of reading within a longitudinal design. One-hundred-and-thirteen fourth grade children were tested on their executive functions, and their decoding skills, linguistic abilities and reading comprehension, one year later. Using Structural Equation Modeling, the results indicated direct effects of working memory and planning on reading comprehension, as well as indirect effects of working memory and inhibition via decoding. The results of the present study on reading comprehension highlight the importance of executive functions in addition to components of the simple view of reading.

Hand gesture recognition of English alphabets using artificial neural network

Human computer interaction (HCI) and sign language recognition (SLR), aimed at creating a virtual reality, 3D gaming environment, helping the deaf-and-mute people etc., extensively exploit the use of hand gestures. Segmentation of the hand part from the other body parts and background is the primary need of any hand gesture based application system; but gesture recognition systems are often plagued by different segmentation problems, and by the ones like co-articulation, movement epenthesis, recognition of similar gestures etc. The principal objective of this paper is to address a few of the said problems. In this paper, we propose a method for recognizing isolated as well as continuous English alphabet gestures which is a step towards helping and educating the hearing and speech-impaired people. We have performed the classification of the gestures with artificial neural network. Recognition rate (RR) of the isolated gestures is found to be 92.50% while that of continuous gestures is 89.05% with multilayer perceptron and 87.14% with focused time delay neural network. These results, when compared with other such system in the literature, go into showing the effectiveness of the system.
Merging Taxonomy with Ecological Population Prediction in a Case Study of Vibrionaceae

ABSTRACT We synthesized population structure data from three studies that assessed the fine-scale distribution of Vibrionaceae among temporally and spatially distinct environmental categories in coastal seawater and animals. All studies used a dynamic model (AdaptML) to identify phylogenetically cohesive and ecologically distinct bacterial populations and their predicted habitats without relying on a predefined genetic cutoff or relationships to previously named species. Across the three studies, populations were highly overlapping, displaying similar phylogenetic characteristics (identity and diversity), and were predominantly congruent with taxonomic Vibrio species previously characterized as genotypic clusters by multilocus sequence analysis (MLSA). The environmental fidelity of these populations appears high, with 9 out of 12 reproducibly associating with the same predicted (micro)habitats when similar environmental categories were sampled. Overall, this meta-analysis provides information on the habitat predictability and structure of previously described species, demonstrating that MLSA-based taxonomy can, at least in some cases, serve to approximate ecologically cohesive populations.
IgE-Activated Mast Cells Inflammatory Cytokines Produced by Cbl-b Is a Negative Regulator of

c-Cbl and Cbl-b E3 ubiquitin ligases are abundantly expressed in hemopoietic cells where they negatively regulate the activity and levels of many cell surface receptors and associated signaling molecules. By comparing bone marrow-derived mast cells from c-Cbl and Cbl-b-deﬁcient mice it has recently been shown that Cbl-b is the dominant family member for negatively regulating signaling responses from high-afﬁnity IgE receptors. In this study, we suggest that a possible reason for the greater enhancement of IgE receptor signaling in Cbl-b-deﬁcient mice is the relatively higher levels of Cbl-b protein over c-Cbl in mast cells compared with other hemopoietic cells. We also directly compare mast cells from c-Cbl and Cbl-b-deﬁcient mice and ﬁnd that loss of Cbl-b, but not c-Cbl, increases cell growth, retards receptor internalization, and causes the sustained tyrosine phosphorylation of Syk and its substrates. However, loss of Cbl-b does not enhance the activation of ERK or Akt, nor does it promote a greater calcium response. Furthermore, loss of Cbl-b or c-Cbl does not increase levels of the Syk or Lyn protein tyrosine kinases. Most notable, however, is the extremely large increase in the production of proinﬂammatory cytokines TNF- (cid:1) , IL-6, and MCP-1 by Cbl-b (cid:2) / (cid:2) mast cells compared with levels produced by c-Cbl (cid:2) / (cid:2) or wild-type cells. This marked induction, which appears to be restricted to these three cytokines, is dependent on IgE receptor activation and correlates with enhanced I (cid:3) B kinase phosphorylation. Thus, Cbl-b functions as a potent negative regulator of cytokines that promote allergic and inﬂammatory reactions. The Journal of Immunology, in BMMCs from wt c-Cbl and Cbl-b are Fixed and permeabilized cells were incubated with rabbit anti-Syk or anti-Lyn Abs before with FITC-conjugated anti-rabbit and analysis by cytometry. , and anti-Lyn immunoblots of lysates BMMCs and antigenic Syk protein levels were examined with rabbit and mouse anti-Syk Abs and both showed lower levels of p72 Syk in unstimulated Cbl-b / compared with wt and c-Cbl (cid:3) / cells. Following antigenic stimulation, the levels of p72 Syk appeared equivalent among the three groups. In addition, anti-Syk Abs revealed higher levels of a p30 form of Syk in Cbl-b (cid:3) / (cid:3) cells. High molecular mass forms of Syk were also evident following antigenic stimulation. These forms of Syk are suggestive of ubiquitylation, a process that appears markedly reduced in Cbl-b (cid:3) / (cid:3) cells. The anti-Lyn blot revealed no differences among the three groups.
Multi-Antenna Downlink Spatial Division Multiplexing with Opportunistic Feedback

In this paper, a new opportunistic feedback and user selection protocol is proposed for the multiple antenna downlink. The proposed scheme uses the structure of zero-forcing dirty paper coding (DPC) at the transmitter and selects users using a contention-based feedback channel. The user selection procedure is divided into stages and within each stage, a user is selected for one spatial channel (defined by the zero-forcing dirty paper coding strategy). The user feedback is controlled by a feedback probability and a feedback threshold. This method of feedback significantly reduces the resources used for feedback compared to dedicating feedback resources for each user. We optimize an approximation to the sum rate expression with respect to these parameters and illustrate the sum rate performance by simulations. The simulation shows that we can achieve good sum rate performance despite the reduction in feedback resources.
