Anonymous Searchable Encryption Scheme for Multi-user Databases (2013)

With the ever advancing technology of fast information processing, protecting data with only access control mechanisms is becoming increasingly difficult. If someone breaks into a database, the entire data will be compromised if it is in plaintext form. One quick remedy is to keep the data in encrypted form. However, encryption will make it difficult to do any operations on the data. This has prompted considerable research in the last decade and has led to various schemes of searchable encryption. It allows search over the encrypted data. There are various techniques which support different levels of querying, making it suitable for variety of applications. However, almost all of them are either symmetric-key or single-user schemes or require key sharing. Here, we are proposing a new scheme which will allow multiple users to encrypt, store and decrypt their own data, along with support for doing data searches over all the data by other users.
Insulin-like growth factor 1 can decrease degradation and promote synthesis of proteoglycan in cartilage exposed to cytokines (1989)

A model system of explanted cartilage has been used in vitro to determine whether insulin-like growth factor 1 (IGF 1), which promotes matrix formation is effective in the presence of cytokines such as interleukin 1 (IL1) and tumour necrosis factor (TNF), which induce net matrix depletion. IGF 1 induced a dose-dependent 2.5-fold stimulation of proteoglycan synthesis, with a half-maximal dose of 25 ng/ml. A similar relative increase occurred in response to IGF 1 (10-100 ng/ml) in cartilage cultured also with IL1 or TNF (5-500 pM). There was no detectable qualitative change in the average molecular size or charge of the aggregating proteoglycan synthesized by explants exposed to IGF 1 alone or with IL1 or TNF. The increased production of prostaglandin E2, which is initiated when IL1 or TNF bind to the chondrocytes, was the same in the presence or absence of IGF 1. The time taken for 50% of pre-labelled proteoglycan to be released from the explants (t1/2) increased in the presence of IGF 1 (100 ng/ml) from 21 to 32 days in control cultures and from 8 to 26 days in cartilage cultured with IL1 (50 pM). It is concluded that IGF 1 enhances the synthesis of aggregating proteoglycan in cartilage exposed to cytokines and can directly decrease both the basal and the cytokine-stimulated degradation of proteoglycan in cartilage.
Role of T-lymphocyte subsets in recovery from respiratory syncytial virus infection in calves (1995)

The role of T-cell subsets in respiratory syncytial virus (RSV) infection was investigated by using monoclonal antibodies (MAbs) to selectively deplete gnotobiotic calves of CD4+, CD8+, or WC1+ gamma delta T-cell receptor+ lymphocytes. Injection of these MAbs produced specific reductions of the target cell populations in the circulation and tissues. Ten days after RSV infection, immunoglobulin M (IgM), IgG1, and IgA antibodies were detected in sera and lung washings from control calves. Depletion of CD8+ T cells had no effect on either the serum or local antibody responses to RSV, whereas depletion of CD4+ T cells suppressed the antibody responses in two of three calves. The IgM and IgA responses were significantly increased in the lung washings of calves from which WC1+ T cells were depleted. Depletion of CD4+ or WC1+ T cells caused no significant delay in virus clearance, although an increase in the extent of pneumonic consolidation was observed in anti-CD4-treated calves. Nasopharyngeal excretion of RSV was prolonged in calves depleted of CD8+ T cells, and virus was isolated in high titers from lung washings of these animals 10 days after infection, whereas virus had been cleared from lung washings of all other animals. The delayed virus clearance was associated with an increase in the severity of pneumonic consolidation in three of four of the calves from which CD8+ T cells were depleted. This study shows that CD8+ T cells play a dominant role in the recovery of calves from RSV infection.
The business of conversations: Market social media surveillance and visibility (2013)

Businesses increasingly rely on social media for personal information, which renders their market more visible. This paper draws on a surveillance studies perspective to consider the growth of market surveillance on social media. Drawing on a series of 13 semi–structured interviews with professionals who use Facebook as a business tool, this paper considers three emerging strategies. Radical transparency imports self–presentation tactics in a corporate realm, furthering corporate visibility. Listening refers to the surveillance of personal information. Finally, a conversational approach combines the visibility of both the market and the corporate actor. While popular literature celebrates this as a kind of mutual transparency, corporate actors are strategic in terms of what they present on social media.
Alkyl <i>N</i>‐methylfuroxanylcarbamates. Synthesis and structure. II (1972)

Abstract From 3‐methyl‐4‐furoxancarboxylic acid hydrazide and 4‐methyl‐3‐furoxancarboxylic acid hydrazide the corresponding azides have been synthesized. 3‐Methyi‐4‐furoxancarboxylic acid azide normally underwent the Curtius reaction to give the expected carbamic acid derivative. The degradation of 4‐methyl‐3‐furoxancarboxylic acid azide led to the N ‐(4‐methylfuroxan‐3‐yl)‐carbamic acid derivative at low temperatures and to N ‐(3‐methylfuroxan‐4‐yl)carbamic acid derivative at higher temperatures.
A DC Voltage-Multiplier Circuit Working as a High-Voltage Pulse Generator (2010)

The intensive use of semiconductor devices enabled the development of a repetitive high-voltage pulse-generator topology from the dc voltage-multiplier (VM) concept. The proposed circuit is based on an odd VM-type circuit, where a number of dc capacitors share a common connection with different voltage ratings in each one, and the output voltage comes from a single capacitor. Standard VM rectifier and coupling diodes are used for charging the energy-storing capacitors, from an ac power supply, and two additional on/off semiconductors in each stage, to switch from the typical charging VM mode to a pulse mode with the dc energy-storing capacitors connected in series with the load. Results from a 2-kV experimental prototype with three stages, delivering a 10- s pulse with a 5-kHz repetition rate into a resistive load, are discussed. Additionally, the proposed circuit is compared against the solid-state Marx generator topology for the same peak input and output voltages.
The SCIP Optimization Suite 6.0 (2018)

The SCIP Optimization Suite provides a collection of software packages for mathematical optimization centered around the constraint integer programming framework SCIP. This paper discusses enhancements and extensions contained in version 6.0 of the SCIP Optimization Suite. Besides performance improvements of the MIP and MINLP core achieved by new primal heuristics and a new selection criterion for cutting planes, one focus of this release are decomposition algorithms. Both SCIP and the automatic decomposition solver GCG now include advanced functionality for performing Benders’ decomposition in a generic framework. GCG’s detection loop for structured matrices and the coordination of pricing routines for Dantzig-Wolfe decomposition has been significantly revised for greater flexibility. Two SCIP extensions have been added to solve the recursive circle packing problem by a problem-specific column generation scheme and to demonstrate the use of the new Benders’ framework for stochastic capacitated facility location. Last, not least, the report presents updates and additions to the other components and extensions of the SCIP Optimization Suite: the LP solver SoPlex, the modeling language Zimpl, the parallelization framework UG, the Steiner tree solver SCIP-Jack, and the mixed-integer semidefinite programming solver SCIP-SDP.
> 3 MW peak power at 266 nm using Nd:YAG/ Cr^4+:YAG microchip laser and fluxless-BBO (2012)

Wavelength conversion efficiency to the UV region is limited by a host of factors. To overcome several of these constraints, we use a fluxless-grown BBO crystal for fourth harmonic conversion of a linearly polarized Nd:YAG microchip laser, passively Q-switched with [110] cut Cr4+:YAG. The high quality BBO crystal used in the picosecond pulse width regime enables 60% conversion efficiency to give 3.4 MW peak power, 250 ps, 100 Hz pulses at 266 nm.

A Long Pulse Modulator For Reduced Size And Cost (2005)

A novel modulator has been designed, built and tested for the TESLA test facility. This e{sup +} e{sup {minus}} accelerator concept uses superconducting RF cavities and requires 2ms of RF power at 10 pps. As the final accelerator will require several hundred modulators, a cost effective, space saving and high efficiency design is desired. This modulator used a modest size switched capacitor bank that droops approximately 20% during the pulse. This large droop is compensated for by the use of a resonant LC circuit. The capacitor bank is connected to the high side of a pulse transformer primary using a series GTO switch. The resonant circuit is connected to the low side of the pulse transformer primary. The output pulse is flat to within 1% for 1.9 ms during a 2.3 ms base pulse width. Measured efficiency, from breaker to klystron and including energy lost in the rise time, is approximately 85%.
Chemical imaging by a computer screen aided scanning light pulse technique (2002)

A scanning light pulse technique (SLPT) for the generation of selective chemical images is demonstrated, using a broadly available programmable light source provided by a standard cathode-rays tube computer screen, which supplies two-dimensional micropositioning and intensity modulation. The concept is tested with a metal–oxide–semiconductor capacitor with catalytic gates of platinum and palladium spatially distributed in transversal directions, which produce distinctive response patterns upon hydrogen or ammonia exposures. The nonlaterally resolved images formed by the weighted contribution of the chemically sensitive areas of the gate, subsequently highlighted by the exciting light along its scanning path, retains the ability of SLPT to generate distinctive chemical images.
Electropolymerization of Bis(2-cyano-2-α-thienylethenyl)arylenes (1998)

The synthesis and the electrochemical studies of 1,3-bis(2-cyano-2-α-thienylethenyl)benzene (1), 1,4-bis(2-cyano-2-α-thienylethenyl)benzene (2), and 2,7-bis(2-cyano-2-α-thienylethenyl)biphenylene (3) are reported herein. While compound 2 could be reversibly reduced to form the corresponding dianion, compounds 1 and 3 show irreversible or quasireversible reductions in their cyclic voltammetric studies. We tentatively attribute the high reactivity of the dianions of 1 and 3 to their diradicaloid behavior. This explanation is further supported by PM3/RHF−PM3/UHF calculations. Compounds 1−3 could be irreversibly oxidized at the potential more positive than +1.3 V. Among these compounds, 3 shows the highest reactivity toward oxidative electropolymerization. The resulting polymer film is relatively stable and electroactive. Although polymeric films of compounds 1 and 2 could be formed at higher monomer concentrations, the films are unstable toward electrochemical oxidation. UV−vis analyses of the polymeric films reveal that electropolymerization of 2 is quenched at the early stage of the polymerization, resulting in significant amounts of oligomers in the matrix. However, biphenylene containing monomer 3 could be smoothly converted to highly conjugated polymers under electrochemical oxidation.

Comparing and contrasting micro-payment models for e-commerce systems (2002)

The current macro-payment systems used by most e-commerce sites are not suitable for high-volume, low-cost produce or service purposes, such as charging per page for Web site browsing. These payment technologies suffer from the use of heavyweight encryption technologies and reliance on always-online authorisation servers. Micro-payment systems offer an alternative strategy of pay-as-you-go charging, even for very low-cost, very high-volume charging. However, several different micro-payment schemes exist, not all of which are suitable for all e-commerce uses. We compare and contrast several micro-payment models and outline a new micro-payment technology which we have been developing.
Nanostructured TiO<sub>2</sub>thin films as porous cellular interfaces (2005)

We report the use of nanostructured TiO2 (NST) as porous cellular adhesion interfaces for microsystems. Integrated NST films and pad arrays with sponge-like morphology were fabricated by aqueous oxidation of Ti films followed by thermal annealing. Cell culture studies indicate significantly (t<0.02 from the student's t-test) greater initial attachment of mouse fibroblast cells on porous NST than on silicon dioxide and nitride films for up to 18 h seeding time. Fibroblasts seeded on NST have flat morphology with numerous processes attaching to walls of NST. These results indicate the potential of using NST as porous cell adhesion films and membranes for bioMEMS applications.

Antialiasing scan-line data (1990)

The output of a scan-line visible-surface algorithm is a collection of scan-line segments with associated simple shading functions, which together define the shading as a function of a continuous variable along each scan line. A hybrid antialiasing method that uses this information fully is presented. The method extends to the case where an image transform maps the scan lines into slanted lines in the output raster coordinates. Edge-slope information can be used to infer data along extra scan lines to improve antialiasing. Results obtained with the method are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Preparation of a novel functional hydrogel consisting of sulfated glucoside-bearing polymer: Activation of basic fibroblast growth factor (1998)

Sulfated poly(glucosyloxyethyl methacrylate) [poly(GEMA)-sulfate] and its hydrogel were synthesized and evaluated to develop novel tissue regeneration assist devices. The poly(GEMA)-sulfate hydrogel was obtained by gamma-ray irradiation. Basic fibroblast growth factor (bFGF) was expected to be subsequently incorporated with hydrogel matrices and activated or released from the matrices. A sustained release of bFGF from the poly(GEMA)-sulfate hydrogel was not realized; however, bFGF from poly(GEMA)-sulfate hydrogel was effectively activated. Poly(GEMA)-sulfate hydrogels are thought to be potential component materials for a tissue engineering matrix.
Studies on the effect of epoxide equivalent weight of epoxy resins on thermal, mechanical, and chemical characteristics of vinyl ester resins (2010)

Abstract Three samples of vinyl ester resins (VERs ) were synthesized using bisphenol‐A‐based epoxy resins of varying epoxide equivalent weights (EEW) and acrylic acid in presence of triphenylphosphine as a catalyst at 80 ± 2°C. The cresyl glycidyl ether was used as reactive diluent during the synthesis of VERs. A suitable reaction mechanism was proposed and discussed for the reactions involving epoxide group and acid groups. This was further confirmed by infrared spectroscopic analysis. The maximum peak temperature from DSC were at 106.05°C, 114.20°C, and 128.86°C for benzoyl peroxide initiated VERs viz. samples V 1 C V , V 2 C V , and V 3 C V , respectively, increased with the increase of EEW of the parent epoxy resin. It has also been found that the films of VER having highest EEW of bisphenol‐A epoxy resin showed best chemical resistance amongst all other VERs in this study. The mechanical properties such as hardness and flexibility also showed a similar trend. The thermal stability was found to decrease with the increase of EEW of bisphenol‐A epoxy resin in the VERs. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
M 3 + ‐Modified LiMn2 O 4 Spinel Intercalation Cathodes: I. Admetal Effects on Morphology and Electrochemical Performance (1997)

Low levels of trivalent cations were utilized to stabilize LiMn<sub>2</sub>O<sub>4</sub> spinel cathode materials against capacity decline during electrochemical cycling. Of the several single-phase products obtained, only those with Cr<sup>3+</sup> and Ga<sup>3+</sup> prevented capacity fade, and only LiCr<sub>0.02</sub>Mn<sub>1.98</sub>O<sub>4</sub> exhibited acceptable initial reversible capacity. The external particle morphology was unchanged by the preparation or the admetal, and the internal structures were all converted to cong tou (onion) configurations during product synthesis. Grain size played a surprising role in cathode performance: <25 μm material had at least 10% lower capacity than larger or as-prepared Cr-doped LiMn<sub>2</sub>O<sub>4</sub>.
Effect of L-arginine on oxygen consumption and haemodynamic function of rat's heart exposed to cold cardioplegic ischaemia and reperfusion. (2002)

Measurement of Strain in Locally Oxidized Silicon using Convergent-Beam Electron Diffraction (1993)

Possibility has been studied for analysis using convergent-beam electron diffraction (CBED) of strain in large-scale integrated circuits (LSIs). In the present study, a strain of 1×10 -4 can be detected, which is sufficient to analyze strain in LSIs. This technique is applied to the measurement of strain in locally oxidized silicon (LOCOS). The silicon substrate is found to have a maximum compressive strain of 4×10 -4 at a point 1.5 µm from the SiO 2 edge. Although the influence of specimen thinning preparation on stress is not negligible, the stress distribution was found to suffer from a uniform shift of tensile stress by about 30 MPa.

Procedural filters for customization of virtual worlds (2011)

Designing virtual game worlds is often a long and labor-intensive process. Moreover, when a game world needs to be slightly altered in appearance, the entire process needs to be repeated, or will at least require some repetitious tasks. Ideally, when the same game world is needed under different circumstances (e.g. in another season, before and after a war, in prosperous or poor economic conditions), the designer should be aided in this process using procedural generation techniques.We propose an approach for the specification of procedural filters that describe how (parts of) virtual worlds should be customized to fit a particular situation based on their semantics and the conditions of the situation. This description will guide the customization process by triggering and parametrizing, among others, procedural instructions that can change the appearance of the virtual world. We will discuss how the generic nature of this approach, which favors reusability, and its integration with semantics, which increases the intuitiveness of the design process, can eliminate many of the repetitious tasks involved in performing these actions manually.We describe an implementation of this approach that shows how some simple procedural filters can i) age an urban environment and simulate the effects of poor living conditions on the look of that environment, and ii) apply a party atmosphere to an ordinary office scene.
