Eurographics Symposium on Geometry Processing 2013 Animation-aware Quadrangulation

Figure 1: Given a sequence of triangle meshes sampling an animation (left), we produce a quadrilateral mesh that can fit all animation frames well (center, yellow). Our mesh better represents natural shape structures, just like meshes designed by artists (center-right), while a quadrangular mesh computed from a single pose with a state-of-the-art method [BZK09] (right, grey) exhibits a much more artificial structure. Abstract Geometric meshes that model animated characters must be designed while taking into account the deformations that the shape will undergo during animation. We analyze an input sequence of meshes with point-to-point correspondence , and we automatically produce a quadrangular mesh that fits well the input animation. We first analyze the local deformation that the surface undergoes at each point, and we initialize a cross field that remains as aligned as possible to the principal directions of deformation throughout the sequence. We then smooth this cross field based on an energy that uses a weighted combination of the initial field and the local amount of stretch. Finally, we compute a field-aligned quadrangulation with an off-the-shelf method. Our technique is fast and very simple to implement, and it significantly improves the quality of the output quad mesh and its suitability for character animation, compared to creating the quad mesh based on a single pose. We present experimental results and comparisons with a state-of-the-art quadrangulation method, on both sequences from 3D scanning and synthetic sequences obtained by a rough animation of a triangulated model.
Resurrecting Inactive Antimicrobial Peptides from Lipopolysaccharide ( LPS ) Trap

26 Host defense antimicrobial peptides (AMPs) are a promising source of antibiotics for the 27 treatment of multiple drug-resistant pathogens. Lipopolysaccharide (LPS), the major 28 component of the outer leaflet of the outer membrane of Gram-negative bacteria, functions as 29 a permeability barrier against a variety of molecules including antimicrobial peptides (AMPs). 30 Further, LPS or endotoxin is the causative agent of sepsis killing 100,000 people per year in 31 the USA alone. LPS can restrict activity of AMPs inducing aggregations at the outer 32 membrane as observed for frog AMPs temporins and also in model AMPs. Aggregated 33 AMPs, as ‘trapped’ by the outer membrane, are unable to traverse through the cell wall 34 causing their inactivation. In this work, we show that these inactive AMPs can overcome LPS 35 induced aggregations while conjugated with a short LPS binding β-boomerang peptide motif 36 and become highly bactericidal. The generated hybrid peptides exhibit activity against Gram37 negative and Gram-positive bacteria in high-salt and detoxify endotoxin. Structural and 38 biophysical studies establish mechanism of action of these peptides in LPS outer membranes. 39 Most importantly, this study provides a new concept for the development of potent broad 40 spectrum antibiotic with efficient outer membrane disruption as the mode of action. 41
Research on Wireless Network and Its Technology

Wireless and mobile networks represent an active research and new technology development area. In this paper we analyze wireless network and discuss the applications of wireless technology. To fully support mobility, a next generation Internet must provide ways to name and route to a much richer set of network elements than just attachment points. It should support routing in terms of names, which identify the actual desired end points, rather than some particular characteristic, such as an address. A new architecture should provide data cleansing mechanisms that prevent corrupted data from propagating through the wireless network.
Human C-Tactile Afferents Are Tuned to the Temperature of a Skin-Stroking Caress

Human C-tactile (CT) afferents respond vigorously to gentle skin stroking and have gained attention for their importance in social touch. Pharmacogenetic activation of the mouse CT equivalent has positively reinforcing, anxiolytic effects, suggesting a role in grooming and affiliative behavior. We recorded from single CT axons in human participants, using the technique of microneurography, and stimulated a unit's receptive field using a novel, computer-controlled moving probe, which stroked the skin of the forearm over five velocities (0.3, 1, 3, 10, and 30 cm s−1) at three temperatures (cool, 18°C; neutral, 32°C; warm, 42°C). We show that CTs are unique among mechanoreceptive afferents: they discharged preferentially to slowly moving stimuli at a neutral (typical skin) temperature, rather than at the cooler or warmer stimulus temperatures. In contrast, myelinated hair mechanoreceptive afferents proportionally increased their firing frequency with stroking velocity and showed no temperature modulation. Furthermore, the CT firing frequency correlated with hedonic ratings to the same mechano-thermal stimulus only at the neutral stimulus temperature, where the stimuli were felt as pleasant at higher firing rates. We conclude that CT afferents are tuned to respond to tactile stimuli with the specific characteristics of a gentle caress delivered at typical skin temperature. This provides a peripheral mechanism for signaling pleasant skin-to-skin contact in humans, which promotes interpersonal touch and affiliative behavior.
Cyber-security of SCADA systems

After a general introduction of the VIKING EU FP7 project two specific cyber-attack mechanisms, which have been analyzed in the VIKING project, will be discussed in more detail. Firstly an attack and its consequences on the Automatic Generation Control (AGC) in a power system are investigated, and secondly the cyber security of State Estimators in SCADA systems is scrutinized.
Postfix Hardware Evaluation Unit for Genetic Algorithms: Application in Fuzzy Clustering

Genetic algorithms are a class of stochastic optimization techniques inspired by biological evolution processes. The power of GAs for solving complex problems is highly used in the design of parallel problem solving machines. High parallelism needs higher number of parallel processors to be used simultaneously. This approach may be costly in terms of efficiency and utilization of processors. GAs are time costly processes mainly because of their time consuming evaluation operations. Development of a low cost hardware evaluation unit may help reducing time complexities of GAs. In this paper, an attempt is made to show how the fitness evaluation operation of any genetically encoded problem can be performed by using a simple hardware. Our hardware uses a postfix notation of the fitness expression. Since, in GAs, the same function is evaluated for a fairly large number of times, we need to compile a postfix expression only once at the beginning of the genetic optimization process. We performed some simulation experiments on function optimization problems, in general. As an example of combinatorial optimization, we considered the fuzzy clustering problem.
Four-Year Observations of T Tauri With Adaptive Optics

We report here on a series of adaptive optics observations of T Tauri made from Dec. 1993 to Nov. 1997. Observations show an arc-like structure extending toward north and north-west. On the south side a bright tail-like structure extends radially in the south-west direction. Both structures seem to be produced by dust scattering. Close to T Tauri, the south structure forms bright clumps near a radio source called T Tau R. From one year to another, the clumps appear to be moving toward T Tauri. The infrared companion is detected for the first time in the J band. Its brightness peaked again in 1996, although the maximum was less pronounced than in 1990. It is found to be resolved with a radius of 54 milliarcsec (7.6 AU at 140 pc). Surprisingly, its orbital speed is found to exceed the escape velocity. This leads to the conjecture that T Tauri is the result of a collision between a young star and a protostar, possibly explaining the peculiar molecular hydrogen emission found in this object. The protostar envelope would have been torn apart forming Burnham’s nebula and leaving the protostar naked, that is visible in the near IR .
Mechanistic Studies with DNA Polymerases Reveal Complex Outcomes following Bypass of DNA Damage

DNA is a chemically reactive molecule that is subject to many different covalent modifications from sources that are both endogenous and exogenous in origin. The inherent instability of DNA is a major obstacle to genomic maintenance and contributes in varying degrees to cellular dysfunction and disease in multi-cellular organisms. Investigations into the chemical and biological aspects of DNA damage have identified multi-tiered and overlapping cellular systems that have evolved as a means of stabilizing the genome. One of these pathways supports DNA replication events by in a sense adopting the mantra that one must “make the best of a bad situation” and tolerating covalent modification to DNA through less accurate copying of the damaged region. Part of this so-called DNA damage tolerance pathway involves the recruitment of specialized DNA polymerases to sites of stalled or collapsed replication forks. These enzymes have unique structural and functional attributes that often allow bypass of adducted template DNA and successful completion of genomic replication. What follows is a selective description of the salient structural features and bypass properties of specialized DNA polymerases with an emphasis on Y-family members.
Reciprocal Activation of Xenobiotic Response Genes by Nuclear Receptors Sxr/pxr and Car

The cytochrome P450 (CYP) gene products such as CYP3A and CYP2B are essential for the metabolism of steroid hormones and xenochemicals including prescription drugs. Nuclear receptor SXR/PXR (steroid and xenobiotic receptor/pregnenolone X receptor) has been shown both biochemically and genetically to activate CYP3A genes, while similar studies have established constitutive androstane receptor (CAR) as a CYP2B regulator. The response elements in these genes are also distinct, furthering the concept of independent regulation. Unexpectedly, we found that SXR can regulate CYP2B, both in cultured cells and in transgenic mice via adaptive recognition of the phenobarbital response element (PBRE). In a type of functional symmetry, orphan receptor CAR was also found to activate CYP3A through previously defined SXR/PXR response elements. These observations not only provide a rational explanation for the activation of multiple CYP gene classes by certain xenobiotics, but also reveal the existence of a metabolic safety net that confers a second layer of protection to the harmful effects of toxic compounds and at the same time increases the propensity for drug–drug interactions. The liver cytochrome P450 (CYP) enzymes represent a supergene family of hemeproteins that catalyze the metabolic conversion to more polar derivatives of an amazing diversity of foreign chemicals (xenobiotics) including various environmental pollutants, carcinogens, and prescription drugs as well as endogenous substrates such as steroid hormones (for reviews, see Gonzalez 1992; Denison and Whitlock 1995). The levels of some CYP enzymes are typically induced by their xenobiotic substrates. For example, administration of glucocorti-coids (both agonists such as dexamethasone [DEX] and antagonists such as RU486), rifampicin (RIF), or pheno-barbital (PB) increases the levels of CYP3A, a family of medically significant isoenzymes involved in the metabolism of more than half of all prescription drugs as well as neutraceuticals and herbal medicines (Maurel 1996). Specificity studies reveal that some (but not all) CYP3A-inducing compounds also activate CYP2B genes (e.g., Strom et al. 1996; Honkakoski and Negishi 1997). The metabolic versatility of CYP3A and CYP2B coupled with their inducibility by xenobiotic substrates constitutes a molecular basis for many clinical drug–drug interactions. Such interactions pose one of the most vexing problems in drug development. These problems arise when P450 inducers such as glucocorticoids, PB, or RIF are administered concurrently with medications such as immunosuppressant cyclosporine A, oral contraceptives and antihypertensives that are normally metabolized by these CYP enzymes (Maurel 1996). Recently, St John's wort, a popular herbal remedy for depression, was found to …
Amorphous Slack Methodology for Autonomous Fault-Handling in Reconfigurable Devices

Amorphous Slack fault handling methodology utilizes adaptive runtime redundancy to improve survivability of FPGA based designs. Unlike conventional static redundancy based methods to achieve fault resilience, the proposed system operates in uniplex arrangement under non-contingent conditions. The proposed fault isolation algorithm is invoked upon fault detection which employs a health metric of the application operating over reconfigurable platform. This assertion applies if a signal-to-noise metric is known, as well as applications that do not possess a readily correlated metric to identify anomalous behavior. In particular, readily available processor cores allow dynamic fault identification by executing a software specification of the signal processing algorithm which is used to periodically validate critical outputs of the high-speed hardware circuit within tolerances. The results from H.263 video encoder and Canny edge detector implemented over Xilinx Virtex-4 device demonstrate autonomous recovery from permanent stuck-at faults while maintaining the throughput during fault-handling operations. The fault-detection and isolation applications are executed on on-chip PowerPC processor while the Circuit-Under-Test (CUT) is realized in hardware fabric. The proposed architecture allows on-chip processor based functional monitoring of the contained hardware resources subjected to the actual inputs of the circuit.
Community mining in co-authorship network

Community is formed by individuals such that those within a group interact with each other more frequently than with those outside the group. Community mining or detection involves discovering groups in a network where an individual's group memberships are not explicitly given. Much of the research on detecting communities in co-authorship networks has been done using publicly available datasets. Discovering communities by using a publication list available from the researchers homepage is a challenging task As the data available from homepages will be in an unstructured form, an interpreter is required to extract the structured co-authorship network to detect communities. The focus of this work is to detect communities in co-authorship network for which the co-authorship network will be constructed using the publication list of researchers homepage. Network centric community detection algorithms: Multi-dimensional scaling, Block model, Spectral clustering and Modularity maximization was applied on co-authorship network to mine communities. The results of evaluation of these algorithms using the measures Internal density, Expansion and Conductance will be discussed in this work.

Bics 2006 – Brain Inspired Cognitive Systems 1 Microprocessor Design Automation: a Dna Based Evolutionary Approach N Venkateswaran Director, Waran Research Foundation [warft]

Process automation has always been one of the prime areas of research. Evolutionary systems have had an edge over their conventional counterparts as they mimic the successful natural selection process. A novel evolutionary approach for the automation of microprocessor design process is discussed in this paper. The microprocessor characteristics are encoded onto a DNA sequence. The combination of DNA sequences of two different microprocessors produces an offspring. These offsprings can radically differ from conventional microprocessors. Such offsprings are detected during the validation phase and selectively added to a gene pool. The architect has many design options as he can choose from a variety of such meaningful DNAs from the gene pool, based on his requirements. Evolution is incorporated through the gene pool and heuristic update process. For simulation, five processors were selected and 38 of their characteristics were encoded onto DNA sequences. It was found that combination of two of these DNA sequences produced valid microprocessors.
On a Problem of E Rd} Os and Turr an and Some Related Results

We employ the probabilistic method to prove a stronger version of a result of Helm, related to a conjecture of Erd} os and Turr an about additive bases of the positive integers. We show that for a class of random sequences of positive integers A, which satisfy jA \ 1; x]j p x with probability 1, all integers in any interval 1; N] can be written in at least c1 log N and at most c2 log N ways as a diierence of elements of A\1;N 2 ]. We also prove several results related to another result of Helm. We show that for every sequence of positive integers M, with counting function M(x), there is always another sequence of positive integers A such that M \ (A ? A) = ; and A(x) > x=(M(x) + 1). We also show that this result is essentially best possible, and we show how to construct a sequence A with A(x) > cx=(M(x) + 1) for which every element of M is represented exactly as many times as we wish as a diierence of elements of A. Notation All sequences we consider are sequences of distinct nonnegative integers. We write N = f0; 1; 2; : : :g. We denote by the lower case indexed letter the members of the sequence and by the capital letter the sequence as a set as well as its counting function. For example A = fa 0 ; a 1 ; a 2 ; : : :g denotes a sequence of distinct nonnegative integers and A(x) = jA \ 0; x]j denotes its counting function. The initial segment A \ 0; x] is denoted by A x. The positive diierence set fa ? b : a; b 2 A; a > bg is denoted by A ? A and the sumset fa+b : a 2 A; b 2 Bg by A+B. We denote by C an arbitrary positive constant and we write a b, if there exists a constant C such that a Cb. By a b or a = (1+o(1))b we mean lima=b = 1 as a certain quantity, which will be clear from the context, approaches a limit. Similarly we write a. b for a (1 + o(1))b. We deene several \representation" functions for a given set A:
Towards Building Loyalty in e-Commerce Applications: Addressing Issues on Personalisation, Persistence & Presentation

In the increasing trend towards e-commerce, vendor-purchaser relations have become de-personalised. Attempts to improve relations by introducing so-called loyalty schemes, which are in fact thinly disguised discount schemes, have failed to redress the balance. On-line, on-site kiosk-based multimedia systems in conjunction with reward schemes can engage the customer's interest but do not necessarily create loyalty. The EU MAPPA Project (EP28831) seeks to add value to such systems in order create loyalty: our means of achieving this is to use Agent technology and by addressing issues on Personalisation, Persistence, and Presentation (the 3Ps). This paper discusses the problems in creating loyalty in electronic commerce. We argue that it is necessary to address the 3Ps inorder to achieve loyalty: that is by understanding the potential value of the customer's IPR (the value of information, interaction, personalisation, privacy, (mutual) respect and re-use). In each case, we analyse the situation in conventional retailing, give guidelines on transferring the value to electronic commerce, and then discuss how the value is realised in the MAPPA system architecture and/or its agents
Features Reduction Using Logic Minimization Techniques

This paper is dedicated to two seemingly different problems. The first one concerns information theory and the second one is connected to logic synthesis methods. The reason why these issues are considered together is the important task of the efficient representation of data in information systems and as well as in logic systems. An efficient algorithm to solve the task of attributes/arguments reduction is presented.
Human gamma-tubulin functions in fission yeast

gamma-Tubulin is a phylogenetically conserved component of microtubule- organizing centers that is essential for viability and microtubule function. To examine the functional conservation of gamma-tubulin, we have tested the ability of human gamma-tubulin to function in the fission yeast Schizosaccharomyces pombe. We have found that expression of a human gamma-tubulin cDNA restores viability and a near-normal growth rate to cells of S. pombe lacking endogenous gamma-tubulin. Immunofluorescence microscopy showed that these cells contained normal mitotic spindles and interphase microtubule arrays, and that human gamma-tubulin, like S. pombe gamma-tubulin, localized to spindle pole bodies, the fungal microtubule-organizing centers. These results demonstrate that human gamma-tubulin functions in fission yeast, and they suggest that in spite of the great morphological differences between the microtubule-organizing centers of humans and fission yeasts, gamma-tubulin is likely to perform the same tasks in both. They suggest, moreover, that the proteins that interact with gamma-tubulin, including, most obviously, microtubule-organizing center proteins, must also be conserved. We have also found that a fivefold overexpression of S. pombe gamma-tubulin causes no reduction in growth rates or alteration of microtubule organization. We hypothesize that the excess gamma-tubulin is maintained in the cytoplasm in a form incapable of nucleating microtubule assembly. Finally, we have found that expression of human gamma-tubulin or overexpression of S. pombe gamma-tubulin causes no significant alteration of resistance to the antimicrotubule agents benomyl, thiabendazole and nocodazole.
