The implementation of Secure Canary Word for buffer-overflow protection (2009)

Chiamwongpaet and Piromsopa introduced secure canary word, an extension of secure bit, as an architectural approach to the protection against buffer-overflow attacks on non-control data (variables and arguments). Secure canary word is based on two existing schemes, secure bit and canary word. The objective of this paper is to propose a new hardware implementation in order to improve the efficiency of secure canary word. To evaluate this design, the hardware simulation is conducted using BOCHS emulator running Linux (Red Hat 6.2) with GCC compiler. Like the prior work, the results confirm that secure canary word can detect buffer-overflow attacks on non-control data. Furthermore, performance is significantly better than the original implementation. This suggests that secure canary word can prevent buffer-overflow attacks on non-control data without any serious performance degradation or storage requirement.
Resistivity reduction and chemical stabilization of organometallic chemical vapor deposited titanium nitride by nitrogen rf plasma (1996)

In situ, nitrogen rf plasma treatment of organometallic chemical vapor deposited (OMCVD) TiN, synthesized by thermal decomposition of tetrakis(dimethylamido) titanium, yielded films with low resistivity and enhanced chemical stability. A sequential OMCVD-plasma treatment process allowed deposition of films with bulk resistivity as low as 400 μΩ cm. The nitridation resulted in reduction of the carbon concentration in the films, and crystallization of TiN. The composition and electrical properties of the nitridized films were found to be stable upon air exposure. The films possess excellent step coverage (≳70% in 0.35 μm device structures with aspect ratio ∼3) and low defect density (∼0.06 cm−2 for defect size ≥0.2 μm).

Pain Assessment in Patients With Fibromyalgia Syndrome (2004)

Pain assessment methods relying on recall might contribute to an apparent improvement in clinical trials in the absence of an intervention; such an effect has been considered a "placebo response." Future clinical trials might consider using a real-time approach to pain assessment, which in this study appeared to mitigate against seeing improvement in the absence of an intervention and demonstrated higher levels of patient adherence.
Immediate reocclusion following a successful thrombolysis in acute stroke: A pilot study (2003)

Immediate reocclusion after successful thrombolysis was angiographically examined in 29 consecutive stroke patients. The reocclusion, which was associated with a high-grade residual stenosis of initially perfused arteries, occurred in four patients. IV abciximab successfully dissolved the thrombus in all four patients. Rapid thrombotic reocclusion after successful thrombolysis is commonly observed in patients after an acute stroke. Administration of abciximab may lead to reperfusion of the reoccluded artery.
Discriminative structure learning of hierarchical representations for object detection (2009)

A variety of flexible models have been proposed to detect objects in challenging real world scenes. Motivated by some of the most successful techniques, we propose a hierarchical multi-feature representation and automatically learn flexible hierarchical object models for a wide variety of object classes. To that end we not only rely on automatic selection of relevant individual features, but go beyond previous work by automatically selecting and modeling complex, long-range feature couplings within this model. To achieve this generality and flexibility our work combines structure learning in conditional random fields and discriminative parameter learning of classifiers using hierarchical features. We adopt an efficient gradient based heuristic for model selection and carry it forward to discriminative, multidimensional selection of features and their couplings for improved detection performance. Experimentally we consistently outperform the currently leading method on all 20 classes of the PASCAL VOC 2007 challenge and achieve the best published results on 16 of 20 classes.
Evaluation of serum concentrations of biomarkers of skeletal metabolism and results of radiography as indicators of severity of osteochondrosis in foals (2004)

The ability of serum biomarkers to indicate osteochondrosis severity appears to depend on stage of disease and is strengthened with radiography. In older foals with more permanent lesions, osteochondrosis severity is significantly related to biomarker concentrations of decreased bone formation and increased cartilage synthesis.
Microalbuminuria as a predictor of a drop in glomerular filtration rate in subjects with non-insulin-dependent diabetes mellitus and hypertension. (1997)

Microalbuminuria is a risk factor for a drop in GRF in NIDDM subjects with hypertension, and a reduction in blood pressure is the only effective way to prevent a loss of GFR in subjects with microalbuminuria.
A 1.8-GHz self-calibrated phase-locked loop with precise I/Q matching (2001)

This paper describes a 1.8-GHz self-calibrated phase-locked loop (PLL) implemented in 0.35-/spl mu/m CMOS technology. The PLL operates as an edge-combining type fractional-N frequency synthesizer using multiphase clock signals from a ring-type voltage-controlled oscillator (VCO). A self-calibration circuit in the PLL continuously adjusts delay mismatches among delay cells in the ring oscillator, eliminating the fractional spur commonly found in an edge-combing fractional divider due to the delay mismatches. With the calibration loop, the fractional spurs caused by the delay mismatches are reduced to -55 dBc, and the corresponding maximum phase offsets between the multiphase signals is less than 0.20. The frequency synthesizer PLL operates from 1.7 to 1.9 GHz and the closed-loop phase noise is -105 dBc/Hz at 100-kHz offset from the carrier. The overall circuit consumes 20 mA from a 3.0-V power supply.
Enhanced Security for Data Sharing in Multi Cloud Storage (SDSMC) (2017)

Multiple Cloud storage has become one of the essential services of cloud computing. This Multi-Cloud storage models allow users to store sliced encrypted data in various cloud drives. Thus, it provides support for various cloud storage services using the single interface rather than using single cloud storage services. Cloud security goal primarily focuses on issues that relate to information privacy and security aspects of cloud computing. This latest data storage service and data moderation prototype focus on malicious insider’s access on stored data, protection from malicious files, removal of centralized distribution of data storage and removal of outdated files or downloaded files frequently. Data owner does not necessarily need to worry about the future of the data stored in the Multi-Cloud server may be extracted or depraved. The other is ingress control of data. The proposed method ensures the file or data cannot get access without the knowledge or permission of the owner. Thus, this research aims at offering an architecture which reduces malicious insiders and file threats with an algorithm that improves data sharing security in Multi- Cloud storage services. This technique will offer a secure environment whereby the data owner can store and retrieve data from Multi-Cloud Environment without file merging conflicts and prevents insider attacks to obtain a meaningful information. The experimental results indicate that the suggested model is suitable for decision making process for the data owners in the better adoption of multi-cloud storage service for sharing their information securely.
Some co-ordination complexes of dimethyl- and diphenyl-magnesium with ethers and amines (1966)

Co-ordination complexes of dimethyl- and diphenyl-magnesium with 1 mol. of tetramethylethylenediamine and 1,2-dimethoxyethane are described, the soluble complexes being monomeric in benzene solution. The bisamine complex of dimethylmagnesium can be sublimed without decomposition, but the others and the tetramethyl-o-phenylenediamine complex of dimethylmagnesium lose ether or amine when heated. Dimethylmagnesium and trimethylethylenediamine form a dimeric complex analogous to those derived from dimethyl-beryllium and -zinc.
A gravitational field model for the earth. (1973)

Two models of the earth's gravitational field have been computed. The first, Goddard Earth Model 1 (GEM 1), has been derived from satellite tracking data. The second, Goddard Earth Model 2 (GEM 2), has been derived from a combination of satellite tracking and surface gravimetric data. The satellite data consisted primarily of optical data processed on 300 weekly orbital arcs for 25 close earth satellites. Surface gravity data were employed in the form of 5 x 5 deg mean free-air gravity anomalies providing about 70% world coverage. Station locations were obtained for 46 tracking sites by combining electronic, laser, and additional optical tracking data with the above satellite data. Analysis of the radial positions of these stations and a value of mean gravity on the geoid indicated a mean equatorial radius for the earth of about 6378.145 meters. Results of geopotential tests on satellite data not used in the solution show that better agreement was obtained with the GEM 1 and GEM 2 models than with the 1969 Smithsonian Standard Earth II model.
Infrastructure Technology for Cloud Services (2011)

The application of a new information and communications technology (ICT) model called cloud computing is finally moving into a full-scale deployment phase in the corporate world as a new business infrastructure and in diverse fields such as primary industry, medical care, and nursing to improve productivity. To expand use of the “cloud,” that is, to dispel worries about using cloud computing, Fujitsu came to reevaluate, redesign, and redevelop its cloud infrastructure technology from the architecture level to achieve a higher dimension in both convenience and reliability. These efforts led to the launching in October 2010 of a commercialized cloud service called “On-demand Virtual System Service” (now known as the “Fujitsu Global Cloud Platform ‘FGCP/S5’” service in Japan and as the “Global Cloud Platform [GCP]” service globally). This “Made in Fujitsu” infrastructure technology is being expanded to data centers in six countries including Japan to promote the provision of cloud services on a global scale. This paper introduces Fujitsu’s cloud infrastructure technology and the global expansion of Fujitsu cloud services.
The <i>Tlx-2</i> homeobox gene is a downstream target of BMP signalling and is required for mouse mesoderm development (1998)

TGFbeta-related factors are critical regulators of vertebrate mesoderm development. However, the signalling cascades required for their function during this developmental process are poorly defined. Tlx-2 is a homeobox gene expressed in the primitive streak of mouse embryos. Exogenous BMP-2 rapidly activates Tlx-2 expression in the epiblast of E6.5 embryos. A Tlx-2 promoter element responds to BMP-2 signals in P19 cells, and this response is mediated by BMP type I receptors and Smad1. These results suggest that Tlx-2 is a downstream target gene for BMP signalling in the primitive streak where BMP-4 and other TGFbeta-related factors are expressed. Furthermore, disruption of Tlx-2 function leads to early embryonic lethality. Similar to BMP4 and ALK3 mutants, the mutant embryos display severe defects in primitive streak and mesoderm formation. These experiments thus define a BMP/Tlx-2 signalling pathway that is required during early mammalian gastrulation.
Phenolic Compounds in Food (1992)

Phenolic compounds including simple phenols and phenolic acids, hydroxycinnamic acid derivatives and flavonoids are bioactive substances occurring widely in food plants. Phenolic compounds are closely associated with the sensory and nutritional quality of fresh and processed plant foods. The enzymatic browning reaction of phenolic compounds, catalyzed by polyphenoloxidase, could cause the formation of undesirable color and flavor and the loss of nutrient in fruits and vegetables. Many phenolic compounds in plants are good sources of natural antioxidants. It is a great interest in recent years that many phenolic compounds in foods have inhibitory effects on mutagenesis and carcinogenesis.
Use of Microorganisms and Enzymes in the Synthesis and Production of Optically Active Agricultural Chemicals (1987)

The production of both specialty and commodity chemicals by enzyme reaction has become a reality due to recent advances in immobilization. These immobilization techniques have provided an economical system for reuse of enzyme and thus provide a route to optical isomers in high enantiomeric yields. This provides specific stereoisomers for agricultural synthesis at reasonable cost. The advantages of stereoisomers include high activity levels as well as reduced toxicity due to the absence of the incorrect stereoisomer. Methods of immobilization will be reviewed with emphasis on immobilization by polyazetidine. Enzymatic reaction via immobilization enzymes and immobilized whole cells will be reviewed with emphasis on the production of agricultural chemicals.
A probabilistic architecture for content-based image retrieval (2002)

The design of an effective architecture for content-based retrieval from visual libraries requires careful consideration of the interplay between feature selection, feature representation, and similarity metric. We present a solution where all the modules strive to optimize the same performance criteria: the probability of retrieval error. This solution consists of a Bayesian retrieval criteria (shown to generalize the most prevalent similarity metrics in current use) and an embedded mixture representation over a multiresolution feature space (shown to provide a good trade-off between retrieval accuracy, invariance, perceptual relevance of similarity, and complexity). The new representation extends standard models (histogram and Gaussian) by providing simultaneous support for high-dimensional features and multi-modal densities and performs well on color texture, and generic image databases.
Intratumoral Administration of Recombinant Human Interleukin 12 in Head and Neck Squamous Cell Carcinoma Patients Elicits a T-Helper 1 Profile in the Locoregional Lymph Nodes (2004)

The objective of this Phase II study was to evaluate the pharmacodynamic and immune effects of intratumorally administered recombinant human interleukin-12 (IL-12) on regional lymph nodes, primary tumor, and peripheral blood. Ten previously untreated patients with head and neck squamous cell carcinoma were injected in the primary tumor two to three times, once/week, at two dose levels of 100 or 300 ng/kg, before surgery. We compared these patients with 20 control (non-IL-12-treated) patients. Toxicity was high, with unexpected dose-limiting toxicities at the 300 ng/kg dose level. Dose-dependent plasma IFN-gamma and IL-10 increments were detected. These cytokine levels were higher after the first injection than after the subsequent injections. A rapid, transient reduction in lymphocytes, monocytes, and all lymphocyte subsets, especially natural killer cells, was observed, due to a redistribution to the lymph nodes. In the enlarged lymph nodes of the IL-12-treated patients, a higher percentage of natural killer cells and a lower percentage of T-helper cells were found compared with control patients. The same pattern was detected in the infiltrate in the primary tumor. Real-time semiquantitative PCR analysis of peripheral blood mononuclear cells in the peripheral blood showed a transient decrease of T-bet mRNA. Interestingly, the peripheral blood mononuclear cells in the lymph nodes showed a 128-fold (mean) increase of IFN-gamma mRNA. A switch from the Th2 to a Th1 profile in the lymph nodes compared with the peripheral blood occurred in the IL-12-treated patients. In conclusion, in previously untreated head and neck squamous cell carcinoma patients, recombinant human IL-12 intratumorally showed dose-limiting toxicities at the dose level of 300 ng/kg and resulted in measurable immunological responses locoregionally at both dose levels.
Phase I dose-escalation and pharmacokinetic study of a novel folate analogue AG2034 (2001)

The novel folate analogue AG2034, which was designed as an inhibitor of GARFT (glycinamide ribonucleotide formyltransferase), was evaluated in this phase I study under the auspices of The Cancer Research Campaign, UK. AG2034 blocks de novo purine synthesis through inhibition of GARFT. A total of 28 patients with histologically proven intractable cancers were enrolled. AG2034 was administered as a short intravenous infusion once every 3 weeks. 8 dose levels ranging from 1-11 mg/m(2)were evaluated with patients receiving up to 6 cycles. Dose-limiting toxicities in the form of mucositis, diarrhoea and vomiting were observed at doses of 6 mg/m(2)and above. Significant levels of thrombocytopenia, neutropenia and anaemia were also recorded. Other sporadic toxicities included fatigue and myalgia. The MTD with this schedule of AG2034 was 5 mg/m(2). Most side effects occurred more frequently with cumulative dosing. In keeping with this, pharmacokinetic analysis revealed evidence of drug accumulation. The AG2034 AUC(0-24)increased by a median of 184% (range 20-389%) from cycle 1 to 3 in all 10 patients examined. No objective antitumour responses were observed in the study.
Splatting of non rectilinear volumes through stochastic resampling (1996)

The paper extends the conventional splatting algorithm for volume rendering non rectilinear grids. A stochastic sampling technique called Poisson sphere/ellipsoid is employed to adaptively resample a non rectilinear grid with a set of randomly distributed points whose energy support extents are well approximated by spheres or ellipsoids. Then volume rendered images can be generated by splatting the scalar values at the new sample points with filter kernels corresponding to these spheres and ellipsoids. Experiments have been carried out to investigate the image quality as well as the time/space efficiency of the new approach, and the results suggest that our approach can be regarded as an alternative for existing fast volume rendering techniques of non rectilinear grids.
Platelet Aggregation in Whole Blood Determined Using the Ultra-Flo 100 Platelet Counter (1982)

The Ultra-Flo 100 Whole Blood Platelet Counter has proved a useful tool for measuring platelet aggregation in whole blood, the extent of aggregation being deduced from the number of single platelets that remain. The technique has allowed us to show that platelets aggregate spontaneously in citrated blood and in heparinized blood but not in whole blood collected into EDTA. The aggregation occurs during storage but its rate is enhanced by stirring and it occurs more readily when the whole blood has been exposed to plastic rather than glass. It occurs much more readily in whole blood from some individuals than from others and the process may involve adenosine diphosphate (ADP). The rate of aggregation in whole blood is enhanced by several aggregating agents including collagen, ADP and sodium arachidonate which are more usually studied in platelet-rich plasma.
A machine learning approach to building domain-specific search engines (1999)

Domain-specific search engines are becoming increasingly popular because they offer increased accuracy and extra features not possible with general, Web-wide search engines. Unfortunately, they are also difficult and timeconsuming to maintain. This paper proposes the use of machine learning techniques to greatly automate the creation and maintenance of domain-specific search engines. We describe new research in reinforcement learning, text classification and information extraction that enables efficient spidering, populates topic hierarchies, and identifies informative text segments. Using these techniques, we have built a demonstration system: a search engine for computer science research papers available at www.cora.justresearch.com. 1 Introduction As the amount of information on the World Wide Web grows, it becomes increasingly difficult to find just what wewant. While general-purpose search engines suchas AltaVista and HotBot offer high coverage, they often provi...

Design / technology co-optimization of strain-induced layout effects in 14nm UTBB-FDSOI CMOS: Enablement and assessment of continuous-RX designs (2016)

We report on the main local layout effect in 14nm Ultra-Thin Buried oxide and Body Fully Depleted Silicon On Insulator (UTBB-FDSOI) CMOS technology [1]. This effect is demonstrated by Nano-Beam Diffraction to be directly induced by the strain in the SiGe channel and reproduced by an accurate electrical compact model. An original continuous-RX design optimizes the stress management, maintaining longitudinal stress component while relaxing the transverse one.
