A Tagless Coherence Directory

A key challenge in architecting a CMP with many cores is maintaining cache coherence in an efficient manner. Directory-based protocols avoid the bandwidth overhead of snoop-based protocols, and therefore scale to a large number of cores. Unfortunately, conventional directory structures incur significant area overheads in larger CMPs. The tagless coherence directory (TL) is a scalable coherence solution that uses an implicit, conservative representation of sharing information. Conceptually, TL consists of a grid of small Bloom filters. The grid has one column per core and one row per cache set. TL uses 48% less area, 57% less leakage power, and 44% less dynamic energy than a conventional coherence directory for a 16-core CMP with 1MB private L2 caches. Simulations of commercial and scientific workloads indicate that TL has no statistically significant impact on performance, and incurs only a 2.5% increase in bandwidth utilization. Analytical modelling predicts that TL continues to scale well up to at least 1024 cores.
The ERCC1/XPF endonuclease is required for efficient single-strand annealing and gene conversion in mammalian cells

The mammalian ERCC1-XPF endonuclease has a suggested role in the repair of DNA double-strand breaks (DSB) by single-strand annealing (SSA). Here, we investigated the role of ERCC1 in homologous recombination in mammalian cells, and confirm a role of ERCC1 in SSA. Interestingly, we also report an unexpected role for ERCC1 in gene conversion. This provides support that gene conversion in mammalian somatic cells is carried out through synthesis-dependent strand annealing, rather than through a double Holliday Junction mechanism. Moreover, we find low frequencies of SSA and gene conversion in G1-arrested cells, suggesting that SSA is not a frequent DSB repair pathway in G1-arrested mammalian cells, even in the presence of perfect repeats. Furthermore, we find that SSA is not influenced by inhibition of CDK2 (using Roscovitine), ATM (using Caffeine and KU55933), Chk1 (using CEP-3891) or DNA-PK (using NU7026).
Facial Expression Recognition Based on Local Phase Quantization and Sparse Representation

In this paper, we propose a new algorithm for facial expression recognition (FER) based on Local Phase Quantization (LPQ) and sparse representation. Firstly, Features are extracted using LPQ descriptor. Then, Sparse Representation-based Classification (SRC) method is used to represent the test expression image by the linear combination of the training expression images. Facial expressions are distinguished by the residue analysis of sparse representation. The proposed algorithm is experimented on Japanese Female Facial Expression (JAFFE) database. The results show that the proposed algorithm is much better than those traditional methods, such as Local Binary Pattern (LBP) + Support Vector Machine (SVM), two-dimensional principal component analysis (2DPCA) + SVM, Linear Discriminant Analysis (LDA) +SVM etc. The performance is also improved obviously compared with the SRC algorithm. In addition, when images are under occlusion, recognition rate of the proposed algorithm also gets the highest recognition rate for FER.
Microbial Purification of Postfermentation Medium after 1,3-PD Production from Raw Glycerol

1,3-Propanediol (1,3-PD) is an important chemical product which can be used to produce polyesters, polyether, and polyurethanes. In the process of conversion of glycerol to 1,3-PD by Clostridium large number of byproducts (butyric, acetic and lactic acid) are generated in the fermentation medium. The aim of this work was to isolate bacteria strains capable of the utilization of these byproducts. Screening of 30 bacterial strains was performed using organic acids as carbon source. Selected isolates were taxonomically characterized and identified as Alcaligenes faecalis and Bacillus licheniformis. The most active strains, Alcaligenes faecalis JP1 and Bacillus licheniformis JP19, were able to utilize organic acids almost totally. Finally, it was find out that by the use of coculture (C. butyricum DSP1 and A. faecalis JP1) increased volumetric productivity of 1,3-PD production (1.07 g/L/h) and the yield equal to 0.53 g/g were obtained in bioreactor fermentation. Moreover, the only by-product present was butyric acid in a concentration below 1 g/L.
Discussion on the Radial Superresolution of the Two-Photon Microfabrication

In order to improve the radial superresolution of the two-photon microfabrication, the superresolution diffraction theory was introduced in detail. The theoretical analysis of the photosensitive resist based on the exciting power and concentration of free radical was given. And the superresolution diffractive optical element was applied in the two-photon microfabrication system. Simulation results indicated that the radial superresolution of the two-photon microfabrication can be improved with the superresolution diffractive optical element.
Threats In SIP Based VoIP Systems

Security tools such as protocol analyzers, vulnerability assessment utilities and security monitoring utilities are amongthe common tools in a security professional‟s arsenal. Such tools have reached a high level of dependence among securityprofessionals for evaluating potential vulnerabilities in such areas as operating systems, device configuration, networking protocols and applications. However, these tools have their limitations, such as (1) where they are applied, (2) how they areimplemented and (3) how they are maintained and updated. Furthermore, while such tools are fairly robust for more maturetechnology, it remains difficult to develop comprehensive security tools for emerging technology. Voice over Internet Protocol is an example of such an emerging technology. This paper explores the known VoIP-related vulnerabilities andtests several of the more popular open source and commercial VoIP security tools with the intention of demonstrating the gap that exists between vulnerability and detection. Understanding this gap will help to identify what issues need to be addressed in the future development of VoIP security tools.
Social role awareness in animated agents

This paper promotes {\itshape social role awareness\/} as a desirable capability of animated agents, that are by now strong affective reasoners, but otherwise often lack the social competence observed with humans. In particular, humans may easily adjust their behavior depending on their respective role in a socio-organizational setting, whereas their synthetic pendants tend to be driven mostly by attitudes, emotions, and personality. Our main contribution is the incorporation of `social filter programs' to mental models of animated agents. Those programs may qualify an agent's expression of its emotional state by the social context, thereby enhancing the agent's believability as a conversational partner or virtual teammate. Our implemented system is entirely web-based and demonstrates socially aware animated agents in an environment similar to Hayes-Roth's Cybercaf\'{e}.
Peritoneal Ultrastructure and Changes with Continuous Ambulatory Peritoneal Dialysis

D espite the stimulus of the success of continuous ambulatory peritonitis (CAPD) as a therapy, the number of reported studies on peritoneal ultrastructure in the last 5 years is still a fraction of what is regularly published on practically any other body tissue. This applies, in fact, to all serosal tissue, pleura, pericardium, and synovium inclusive. Our knowledge is therefore inferior to most other tissues, where a much more intensive interest has been shown in the ultrastructure as a natural requisite to any proper understanding of molecular biology or pathology.
Mistakes That Heterosexual People Make When Trying to Appear Non-Prejudiced

ABSTRACT In two studies, lesbians, gay men and bisexuals were queried concerning mistakes that well-meaning heterosexual people have made when interacting with them. In qualitative, open-ended research, we determined that the most common mistakes concerned heterosexuals' pointing out that they know someone who is gay, emphasizing their lack of prejudice, and relying on stereotypes about gays. Following up with a quantitative, close-ended questionnaire, we determined that the mistakes respondents experienced most often involved heterosexuals (a) relying on stereotypes and (b) ignoring gay issues; the most annoying mistakes were heterosexuals (a) using subtle prejudicial language and (b) not owning up to their discomfort with gay issues. We used two theoretical perspectives, shared reality theory and the contact hypothesis, to analyze the quantitative responses. Implications for intergroup relationships between heterosexual people and gay people are discussed.
Two-stage downlink beamforming in MISO multicell networks with limited backhaul signaling

A two-stage downlink beamforming design is proposed for multicell multi-input single-output channels with limited backhaul capacity and local channel state information (CSI). The first stage is to maximize the signal-to-leakage-plus-noise ratio with local CSI. Each base station (BS) then calculates the corresponding channel gains and shares them with all other BSs, which typically requires low-rate backhaul signaling. Finally, all the BSs design their beamforming vectors in pursuit of increasing the sum-rate with the shared information. Simulation results show that the proposed scheme shows the sum-rate higher than that of the state-of-the-art scheme and even close to that of the scheme with global CSI even without vector channel information.
Of mice, flies – and men? Comparing fungal infection models for large-scale screening efforts

ABSTRACT Studying infectious diseases requires suitable hosts for experimental in vivo infections. Recent years have seen the advent of many alternatives to murine infection models. However, the use of non-mammalian models is still controversial because it is often unclear how well findings from these systems predict virulence potential in humans or other mammals. Here, we compare the commonly used models, fruit fly and mouse (representing invertebrate and mammalian hosts), for their similarities and degree of correlation upon infection with a library of mutants of an important fungal pathogen, the yeast Candida glabrata. Using two indices, for fly survival time and for mouse fungal burden in specific organs, we show a good agreement between the models. We provide a suitable predictive model for estimating the virulence potential of C. glabrata mutants in the mouse from fly survival data. As examples, we found cell wall integrity mutants attenuated in flies, and mutants of a MAP kinase pathway had defective virulence in flies and reduced relative pathogen fitness in mice. In addition, mutants with strongly reduced in vitro growth generally, but not always, had reduced virulence in flies. Overall, we demonstrate that surveying Drosophila survival after infection is a suitable model to predict the outcome of murine infections, especially for severely attenuated C. glabrata mutants. Pre-screening of mutants in an invertebrate Drosophila model can, thus, provide a good estimate of the probability of finding a strain with reduced microbial burden in the mouse host. Summary: Can the fitness of deletion mutants in a murine model be predicted by their virulence in Drosophila melanogaster? For a fungal pathogen, the answer is, mostly, yes.
Impact of dialect use on a basic component of learning to read

Can some black-white differences in reading achievement be traced to differences in language background? Many African American children speak a dialect that differs from the mainstream dialect emphasized in school. We examined how use of alternative dialects affects decoding, an important component of early reading and marker of reading development. Behavioral data show that use of the alternative pronunciations of words in different dialects affects reading aloud in developing readers, with larger effects for children who use more African American English (AAE). Mechanisms underlying this effect were explored with a computational model, investigating factors affecting reading acquisition. The results indicate that the achievement gap may be due in part to differences in task complexity: children whose home and school dialects differ are at greater risk for reading difficulties because tasks such as learning to decode are more complex for them.
Nb-Doped 0 . 8 BaTiO 3-0 . 2 Bi ( Mg 0 . 5 Ti 0 . 5 ) O 3 Ceramics with Stable Dielectric Properties at High Temperature

Nb-doped 0.8BaTiO3-0.2Bi(Mg0.5Ti0.5)O3 ceramics were prepared by conventional solid-state method. The dielectric properties and the structural properties were investigated. When Nb2O5 is doped into 0.8BT-0.2BMT system, a small amount of Ba4Ti12O27 secondary phase is formed. The lattice parameters gradually increase with the Nb2O5 doping. It is found that the temperature-capacitance characteristics greatly depend on Nb2O5 content. With the addition of 3.0 mol% Nb2O5, a 0.8BT-0.2BMT ceramic sample could satisfy the EIA X9R specification. This material is promising for high-temperature MLCC application.
Critical Buckling Strain in High Strength Steel Pipes Using Isotropic-Kinematic Hardening

High strength steel pipes (HSSP) have become more popular recently for highly pressurized pipelines built to transport natural gas from remote fields to energy markets. Material tests on HSSP showed significant material anisotropy caused by the pipe making process, UOE. A combined isotropic-kinematic hardening material model is developed based on observations made on longitudinal and transverse stress strain data of HSSP. This material model combines linear isotropic hardening with Armstrong-Fredrick kinematic hardening and can be easily calibrated by longitudinal and transverse tension coupon test results. The proposed material model is used to show how considering material anisotropy affects the critical buckling strain of HSSP in the longitudinal direction. Finite element (FE) models are developed to simulate one pressurized and one unpressurised HSSP tested under monotonic displacement-controlled bending. Isotropic and anisotropic material modeling methods are used for each HSSP models. In the isotropic material model, longitudinal stress-strain data of HSSP material is used to define the stress-strain relationship. In the anisotropic model combined hardening material model, calibrated by longitudinal and transverse HSSP stress-strain data, is used. Critical buckling strain predictions by isotropic and anisotropic models of these pipes are compared with test results and also with some available criteria in standards and literatures. These comparisons show that anisotropic models give predictions closer to test results.Copyright © 2010 by ASME
Characteristics of CdS nanowires grown in a porous alumina template using a two-cell method

CdS nanowires have been grown by a two-cell chemical method using a porous alumina template. Field-emission scanning and transmission electron microscopy show the growth of nanowires of diameters ranging from 100 to 110 nm and 50 to 60 nm for two different templates. The surface topography of the template filled with CdS has been studied using atomic force microscopy. The microstructural properties of the nanowires have been studied by high resolution x-ray diffraction. UV–visible spectroscopy of nanowires exhibits a clear blue shift due to quantum confinement. The photoluminescence spectra show green emission due to the defect states of the nanowires and the resonance Raman spectra revealed the stoichiometric phase of CdS with good crystallinity.
Oncofetal mucin Ml epitope family: Characterization and expression during colonic carcinogenesis

The gastric mucin M1 antigens, markers associated with colonic carcinogenesis, have been characterized by new anti‐mucin monoclonal antibodies (MAbs). These MAbs, obtained against mucins isolated from a human ovarian mucinous cyst (MAbs 19M1, 21M1 and 45M1) and from a pancreatic adenocarcinoma (MAb 96RA), were compared with 5 other anti‐M1 mucin MAbs described previously, which characterized the a, b, c, d and e mucin M1 epitopes. Using immunoperoxidase, these new MAbs exclusively stained the surface gastric epithelium of normal human gastro‐intestinal tract and reacted with fetal, precancerous and cancerous colonic mucosa, but not with normal colon. Immunoradiofixation studies showed that these new MAbs are directed against 3 epitopes (f, g and h) which are different from the a, b, c, d and e mucin M1 epitopes, though present on the same a immunoreactive high‐molecular‐weight components (> 1,000 kDa) with a density of 1.4 by CsCl‐density‐gradient ultracentrifugation. M1 antigenicity is characterized by a family of 8 different M1 epitopes which were destroyed with β‐mercaptoethanol (except for the f epitope), sensitive to a 5 hr trypsin treatment and resistant to 5 mM periodate (except for the h epitope). Some epitopes (b, c and d) showed increasing immunoreactivity after 20 mM periodate treatment, suggesting cryptic location. In rat‐colon adenocarcinomas, M1 mucin epitopes were masked but could be decrypted using high periodate treatment, similar to normal rat gastric mucosa, thus suggesting the absence of drastic changes in the saccharide coat of the peptide mucin portion bearing M1 epitopes. Cryptic location, periodate resistance, sensitivity to protease and conformational behavior strongly suggest that the peptidic core of gastric (or fetal colonic) mucin plays a role in M1 immunoreactivity. Indeed, the resurgence of M1 antigens during colonic carcinogenesis is due to re‐expression of the peptide core of gastric (or fetal colonic) mucins.
Plasma oxytocin during pregnancy and lactation in the cynomolgus monkey.

Plasma levels of oxytocin were measured during pregnancy and lactation in a group (n = 23) of cynomolgus monkeys (Ma coca fascicularis). Blood samples were taken biweekly from conscious animals during the last trimester of pregnancy and continuing through 6 weeks of lactation. Oxytocin was measured by a specific and sensitive radioiminunoassay which was developed for this study. The assay was useful for measuring plasma levels of oxytocin since it had excellent sensitivity (‘\‘0.3 pg/assay tube) and a 50% displacement level of 5 pg/assay tube. Recovery studies and measurement of serial dilutions of extracted plasma demonstrated that the assay was valid for determination of plasma oxytocin in the cynomolgus monkey. Results showed that oxytocin was low throughout pregnancy, peaked on the date of parturition, and returned to baseline during lactation. In samples taken 1 week prepartum, oxytocin was 2.1 ± 0.26 and increased to 22.4 ± 6.7 pg/mi on the date of parturition (mean ± SEM). Oxytocin was also measured in a subgroup of animals (n = 7) in which the pregnancies terminated in stillbirth or spontaneous abortion.
Optimal SIR-based power updates in wireless CDMA communication systems

In this paper we present two new control algorithms that potentially can be used as efficient techniques for power updates in wireless CDMA communication networks. The algorithms are obtained by optimizing the signal-to-interference error. The control laws are distributed, respectively linear and bilinear, and require either estimation of the channel interference (or a quantity inversely proportional to the signal interference) or the development of efficient numerical algorithms for solving the set of algebraic equations obtained. In addition, ideas of how to accelerate the convergence of a Nash game power control algorithm are presented.
Realistic and interactive simulation of rivers

In this paper we present interactive techniques for physics-based simulation and realistic rendering of rivers using Smoothed Particle Hydrodynamics. We describe the design and implementation of a grid-less data structure to efficiently determine particles in close proximity and to resolve particle collisions. Based on this data structure, an efficient method to extract and display the fluid free surface from elongated particle structures as they are generated in particle based fluid simulation is presented. The proposed method is far faster than the Marching Cubes approach, and it constructs an explicit surface representation that is well suited for rendering. The surface extraction can be implemented on the GPU and only takes a fraction of the simulation time step. It is thus amenable to real-time scenarios like computer games and virtual reality environments.
A Queuing Mechanism to Alleviate Flooding Attacks in Probabilistic Delay Tolerant Networks

Probabilistic routing protocols in Delay Tolerant Networks (DTN) make use of the mobility history in its prediction when making a forwarding decision. However, the predictive property can expose DTN to more advanced security threats. One security threat is enhanced flooding attack which can be more penetrative if properly planned as malicious nodes have prior knowledge of their victims. However, through the investigation of various flooding techniques, we propose to capitalize this very probabilistic feature to confine and mitigate flooding attacks through a queuing mechanism based on this probabilistic feature. To demonstrate our concept, we formulated a solution for Probabilistic Routing Protocol using History of Encounters and Transitivity (PRoPHET), which is a routing protocol in DTN. The PRoPHET protocol along with our proposed queuing policy does not require global knowledge about the network, and hence is a distributed scheme suitable for DTN.
Kaiman filtering with scheduled measurements — Part II: Stability and performance analysis

For the purpose of reducing communication rate, we have proposed two types of measurement innovation based scheduling algorithm for state estimation of linear discrete-time stochastic systems in our companion paper. More specifically, the first one is an iterative scheduling algorithm, which sequentially triggers sensor communication during each sampling interval. The second one is simpler and only the vector measurement outside a deadzone will be communicated to estimator. This paper is devoted to stability and performance analysis for the derived optimal estimator under the above schedulers. Necessary and sufficient conditions for stability of the established estimation framework are established. Moreover, it is shown that under a given communication rate, the first scheduling algorithm outperforms the second one. An illustrative example is included to validate our theoretic results.
