Policy-based Security Assessment of Mobile End-user Devices - An Alternative to Mobile Device Management Solutions for Android Smartphones (2013)

For security-critical applications, the integrity and security of end-user devices is of particular importance. This especially applies to mobile applications that use smartphones to process security-critical data. Unfortunately, users often compromise the security of smartphones by disabling security features for convenience reasons or by unintentionally installing malware from untrusted application sources. Mobile device management (MDM) solutions overcome this problem by providing means to centrally manage and configure smartphones. However, MDM is mainly suitable for corporate environments but often cannot be applied in non-corporate fields of application such as m-banking or m-government. To address this problem, we propose an alternative approach to assure the security and integrity of smartphones. Our approach relies on a device assessor that evaluates the current state of a smartphone according to a security policy. Integration of this device assessor allows smartphone applications to condition the processing of security-critical data on the smartphone's compliance with a defined security policy. We have shown the practicability of the proposed approach by means of a concrete implementation for the Android platform. We have evaluated this implementation on different Android devices. Obtained results show that our approach constitutes an appropriate alternative for scenarios, in which MDM cannot be applied.

Image dataset for testing search and detection models (2001)

The TNO Human Factors Searchu2 image dataset consists of: a set of 44 high-resolution digital color images of different complex natural scenes, the ground truth corresponding to each of these scenes, and the results of psychophysical experiments on each of these images. The images in the Searchu2 dataset are a subset of a larger set that has been used in a visual search and detection experiment. Each scene (image) contains a single military vehicle that serves as a search target. The image dataset, an Excel file with the ground truth and observer data, and an extensive report describing the dataset are available on CD-ROM (requests by email to the first author). The dataset can be used to develop and validate digital metrics that compute the visual distinctness (contrast, conspicuity, or saliency) of targets in complex scenes, and models of human visual search and detection. The dataset has already been used in more than ten different studies in the literature, ranging from studies evaluating target detectability metrics to eye movement studies and attempts to model the human visual system. In addition to this work, eight other articles in this special section address the Searchu2 dataset.
Measurement of adenylate cyclase activity in the right ventricular endomyocardial biopsy samples from patients with chronic congestive heart failure (2000)

A highly sensitive fluorometric assay technique was adopted in order to examine the adenylate cyclase activity in the minute right ventricular endomyocardial biopsy samples from patients with chronic congestive heart failure (n = 10). Norepinephrine (10(-4) M) and adenosine (10(-3) M) were incubated for 30 min with 10 microl of membrane preparation (1-2 mg protein/mg) to analyze the extent of the receptor-coupled adenylate cyclase activity. Forskolin (10(-4) M) stimulation was used to estimate the maximum adenylate cyclase activity (pmol/mg protein/min, mean +/- SE). The new microanalytical cyclic AMP assay involves four steps: enzymatic destruction of noncyclic adenine nucleotides and phosphorylated metabolites, conversion of cyclic AMP to ATP, amplification of ATP by enzymatic cycling, and fluorometric measurement of NADPH, which is generated in proportion to initial cyclic AMP levels. Basal and forskolin-stimulated maximum adenylate cyclase activities were 75 +/- 8 and 123 +/- 15, respectively. Norepinephrine increased the adenylate cyclase activity to 107 +/- 14, while adenosine tended to decrease it to 65 +/- 7. In addition, elimination of adenosine by adenosine deaminase (10 U/ml) slightly increased the adenylate cyclase activity to 82 +/- 9. These results indicate that the adenylate cyclase activity can be measured in minute endomyocardial biopsy samples. Use of this new approach shows promise of becoming a new and potentially important way to predict the efficacy of pharmacological treatment.
Tomorrow's weather forecast: automatic code generation for atmospheric modeling (1997)

The Ctadel programming environment transforms high-level partial differential equation (PDE) problem specifications into efficient codes for serial, vector and parallel computer architectures using computing-cost heuristics and architecture-specific symbolic transformations. Ctadel-generated codes for the Hirlam weather forecasting system perform comparably with handwritten codes.
Ad Extirpanda: 1914–1915 (1995)

The First World War, breaking out in summer 1914, sealed the fate of old Russia. Probably there would eventually have been a revolution. Having survived his ordeals of 1905–6, the emperor had tried to restore his autocratic powers and had been suspicious of his premier Petr Stolypin’s co-operation with the State Duma. Yet the imperial state had lost its ability to repress all opposition at will. The monarch’s truculence narrowed the ground for political compromise and evolution; it also made more likely the ultimate success of the more radical among his opponents. The nature of an anti-Romanov revolution would very probably have been different if Russia had not gone to war. In mid-1914, before the war, there was no economic crisis. Agricultural production and the trade in farm products had never been greater, and industrial output was expanding. Social conflicts were fierce but not uncontrollable. Thus the major catalysts for the Bolshevik party to advance to power, as it did in 1917, were weak. No doubt the Bolsheviks would have exerted much influence in the course of any conceivable revolution even in a Russia which was at peace and was economically buoyant; but they surely would not have become the monopolistic party of government. It is worth recalling that in 1914 they did not intend to initiate a socialist revolution, and that Lenin declared that the next stage in the country’s development would be bourgeois.
T-Tube for Middle Ear Ventilation (1973)

Mechanism of Antiandrogen Action:  Key Role of Hsp90 in Conformational Change and Transcriptional Activity of the Androgen Receptor (2002)

Activation of the androgen receptor (AR) is induced by ligand binding through conformational changes leading to control of gene expression. Antiandrogens compete with androgens for AR occupancy and subsequently block at least one step in AR action. Analysis of nuclear transfer kinetics using the GFP-AR fusion protein and partial proteolysis analysis provided evidence that the ligand-bound receptor was in equilibrium between at least two distinct conformations, leading to the production of 35 and 29 kDa trypsin-resistant fragments. It also indicated that this equilibrium may regulate the rate of nuclear transfer. The slowing of nuclear transfer by antiandrogens was correlated with the amount of receptor in conformation leading to the 35 kDa trypsin-resistant fragment. To establish the role of heat shock protein (hsp) 90 activity in antiandrogenic action, the effect of geldanamycin (GA) was evaluated in both in vitro assays and live cells. We demonstrated that in vitro hsp90s are required to stabilize the receptor in the inactive conformation and that hsp90 activity is involved in the integrity and nuclear transfer of agonist- and antagonist-bound AR. Furthermore, nuclear transfer is not the only step affected by GA since this compound was also active on a constitutively nuclear AR (GFP-NLS-AR). Hsp90 inactivation impedes interaction of androgen-bound GFP-NLS-AR with nuclear components and inhibits transcriptional activity. We conclude that hsp90s are required for the acquisition of active conformation in agonist-bound AR to regulate nuclear transfer, nuclear matrix binding, and transcriptional activity. Pure antiandrogens block the transconformational change of AR in an intermediary complex unable to acquire the active conformation and to dissociate the hsp90.
Smart Woven Fabrics In Renewable Energy Generation (2011)

Initially, the first purpose of fabric making was only for covering the body and sheltering. However, with a growing population and ever improving advanced technologies, today’s fabrics are mostly used for fashion and performance thus enhancing the standard of people’s everyday life and enjoyment. Most of the technologies which increase the standard of living also increase carbon emission and adversely affect human life indirectly. Warming buildings, using cars, provide hot water, cooking food etc. need energy generated by using coal, gas, fuel or electricity. Burning gas and fuel accelerate the threat of nature and eventually contribute to global warming. Even electricity generation causes carbon emission unless it is generated by using renewable energy sources. Interest in providing renewable usable electrical power from the environment has grown, particularly in the elimination of battery usage, because of their sizeable dimensions, weight and limited lifetime. Since global warming is being considered as the biggest danger for the nature, many scientists and researchers have brought a new breath to their researches. As almost all areas of renewable science and technology, researchers are now working in the field of textile fabrics capable of generating green electricity. Undoubtedly, weaving is the oldest fabric making method which has been a part of human life for protection from nature’s elements and hazards. It is now possible to produce smart woven fabrics by combining the oldest fabric making method with smart fibre material technologies. The chapter named “Smart Woven Fabrics in Renewable Energy Generation“ contains a brief introduction to smart materials, focusing on piezoelectricity and polymer based piezoelectric fibre production. The rest of the chapter explains how to produce smart woven structures by integrating smart fibres into the fabric during weaving process and examples for possible applications for energy regeneration from nature’s elements are given.
Isolation and partial characterisation of ACV synthetase from Cephalosporium acremonium and Streptomyces clavuligerus. (1990)

δ-(L-α-Aminoadipoyl)-L-cysteinyl-D-valine (ACV) synthetase was isolated and partially characterised from Cephalosporium acremonium CO728 and Streptomyces clavuligerus. The purification procedure resulted in a 745- and 277-fold increase in specific enzyme activity, respectively. Both enzymes had similar apparent molecular masses of ca. 300 kdaltons by SDS-polyacrylamide electrophoresis, under reducing and denaturing conditions, and in excess of 600 kdaltons in the native state by gel filtration. Attempts to obtain an N-terminal amino acid sequence of ACV synthetase from C. acremonium were unsuccessful, hence internal amino acid sequence data were obtained after tryptic digestion of the protein. Phosphopantothenic acid was shown to be associated with the enzyme from both sources, which suggests the possible involvement of pantothenate as a 'swinging arm' in the formation of the tripeptide ACV.
Plant-derived anticancer agents - curcumin in cancer prevention and treatment. (2013)

Nowadays cancer is still a major public health issue. Despite all the progresses made in cancer prevention, diagnosis and treatment, mortality by cancer is on the second place after the one caused by cardiovascular diseases. The high mortality and the increasing incidence of certain cancers (lung, prostate, colorectal) justify a growing interest for the identification of new pharmacological agents efficient in cancer prevention and treatment. In the last fifty years many plant-derived agents (vinblastine, vincristine, vindesine, paclitaxel, docetaxel, topotecan, irinotecan, elliptinium) played a major role in cancer treatment. Other very promising plant-derived anticancer agents (combrestatins, betulinic acid, roscovitine, purvalanols, indirubins) are in clinical or preclinical trials. Curcumin, a liposoluble polyphenolic pigment isolated from the rhizomes of Curcuma longa L. (Zingiberaceae), is another potential candidate for new anticancer drug development. Curcumin has been reported to influence many cell-signaling pathways involved in tumor initiation and proliferation. Curcumin inhibits COX-2 activity, cyclin D1 and MMPs overexpresion, NF-kB, STAT and TNF-alpha signaling pathways and regulates the expression of p53 tumor suppressing gene. Curcumin is well-tolerated but has a reduced systemic bioavailability. Polycurcumins (PCurc 8) and curcumin encapsulated in biodegradable polymeric nanoparticles (NanoCurc) showed higher bioavailability than curcumin together with a significant tumor growth inhibition in both in vitro and in vivo studies.

The ATIS spoken language systems pilot corpus (1990)

Speech research has made tremendous progress in the past using the following paradigm:• define the research problem,• collect a corpus to objectively measure progress, and• solve the research problem.Natural language research, on the other hand, has typically progressed without the benefit of any corpus of data with which to test research hypotheses. We describe the Air Travel Information System (ATIS) pilot corpus, a corpus designed to measure progress in Spoken Language Systems that include both a speech and natural language component. This pilot marks the first full-scale attempt to collect such a corpus and provides guidelines for future efforts.
A low-power in-order/out-of-order issue queue (2004)

To better address power concerns, a good design strategy should be flexible enough to dynamically reconfigure available resources according to the application's needs such that extra power is dissipated only when it is really needed. In this work, we focus on power-aware solutions for the issue queue (IQ) in an out-of-order superscalar processor. We propose two schemes that partition the IQ into FIFOs such that only the instructions at the head of each FIFO may request to issue. We then monitor the processor and dynamically vary the number and/or size of FIFOs in accordance with utilization. Experimenting with two different distributions in power dissipation, we show up to 69% reduction in power dissipation in the wakeup and arbitration loop, while constraining performance degradation to be no more than 5%.
Eavesdropping Strategies and Rejected-data Protocols in Quantum Cryptography (1993)

Abstract We show that rejected-data protocols for quantum cryptography are secure against generalized intercept/resend strategies of an eavesdropper provided that the legitimate users of the communication channel use at least three bases. We discuss the connection between this result and the recently-developed protocol based on violations of a suitably-constructed Bell-type inequality for single particles. We also give a new estimate of the probability that an eavesdropper remains undetected under the original protocol and thereby show that the optimal strategies available to an eavesdropper are further limited to those which randomize the errors between the sub-ensembles of data. This result also has implications for the way in which the legitimate users of the channel choose their test data.
Fast Apple (<i>Malus</i> × <i>domestica</i>) and Tobacco (<i>Nicotiana tobacum</i>) Leaf Polyphenol Oxidase Activity Assay for Screening Transgenic Plants (2000)

A spectrophotometric assay method for the analysis of polyphenol oxidase (PPO), in apple and tobacco leaves, has been optimized to increase efficiency in the screening of large numbers of transgenic plants. Crude protein extracts from leaf punches were prepared in a FastPrep homogenizer. The addition of Triton X-100 during extraction resulted in 44 and 74% increases in the PPO activity recovered, from apple and tobacco, respectively. The enzyme kinetics differed markedly between apple and tobacco. Apple leaf PPO was isolated in a latent state and was activated by the addition of SDS. In contrast, tobacco PPO activity was inhibited by SDS, particularly at acidic pH. Apple PPO showed a pronounced pH optimum around pH 6, whereas the pH profile for tobacco PPO was much flatter, with a broad optimum around pH 4. The calculated Km' value for apple PPO, using 4-methylcatechol as substrate, was 8.1, and for tobacco the Km was 4.3. The PPO reaction was strongly inhibited by tropolone, a Cu competitor, and restored by the addition of Cu2+. Several factors affecting variability in leaf PPO activity levels in plants are discussed.
Outcome variables for osteoarthritis clinical trials: The OMERACT-OARSI set of responder criteria. (2003)

Improvement in analysis and reporting results of osteoarthritis (OA) clinical trials has been recently obtained because of harmonization and standardization of the selection of outcome variables (OMERACT 3 and OARSI). Moreover, OARSI has recently proposed the OARSI responder criteria. This composite index permits presentation of results of symptom modifying clinical trials in OA based on individual patient responses (responder yes/no). The 2 organizations (OMERACT and OARSI) established a task force aimed at evaluating: (1) the variability of observed placebo and active treatment effects using the OARSI responder criteria; and (2) the possibility of proposing a simplified set of criteria. The conclusions of the task force were presented and discussed during the OMERACT 6 conference, where a simplified set of responder criteria (OMERACT-OARSI set of criteria) was proposed.
Dynamical Remodeling of the Transcriptome during Short-Term Anaerobiosis in <i>Saccharomyces cerevisiae</i> : Differential Response and Role of Msn2 and/or Msn4 and Other Factors in Galactose and Glucose Media (2005)

In contrast to previous steady-state analyses of the O(2)-responsive transcriptome, here we examined the dynamics of the response to short-term anaerobiosis (2 generations) in both catabolite-repressed (glucose) and derepressed (galactose) cells, assessed the specific role that Msn2 and Msn4 play in mediating the response, and identified gene networks using a novel clustering approach. Upon shifting cells to anaerobic conditions in galactose medium, there was an acute ( approximately 10 min) yet transient (<45 min) induction of Msn2- and/or Msn4-regulated genes associated with the remodeling of reserve energy and catabolic pathways during the switch from mixed respiro-fermentative to strictly fermentative growth. Concomitantly, MCB- and SCB-regulated networks associated with the G(1)/S transition of the cell cycle were transiently down-regulated along with rRNA processing genes containing PAC and RRPE motifs. Remarkably, none of these gene networks were differentially expressed when cells were shifted in glucose, suggesting that a metabolically derived signal arising from the abrupt cessation of respiration, rather than O(2) deprivation per se, elicits this "stress response." By approximately 0.2 generation of anaerobiosis in both media, more chronic, heme-dependent effects were observed, including the down-regulation of Hap1-regulated networks, derepression of Rox1-regulated networks, and activation of Upc2-regulated ones. Changes in these networks result in the functional remodeling of the cell wall, sterol and sphingolipid metabolism, and dissimilatory pathways required for long-term anaerobiosis. Overall, this study reveals that the acute withdrawal of oxygen can invoke a metabolic state-dependent "stress response" but that acclimatization to oxygen deprivation is a relatively slow process involving complex changes primarily in heme-regulated gene networks.
Rhodium catalyzed C–H olefination of N-benzoylsulfonamides with internal alkenes (2011)

An annulation via tandem rhodium catalyzed C-H olefination of N-benzoylsulfonamides with internal olefins followed by C-N bond formation is disclosed. A N-substituted quaternary center is formed during the reaction thus providing efficient access to a series of 3,3-disubstituted isoindolinones.
A semi-autonomous remote controlled mobile robot (1980)

Mobile robots offer more flexibility and scope than the fixed single arm type. French researchers are putting considerable effort into developing such devices and here results of their efforts are described.
Structure of the human α<sub>1</sub>acid glycoprotein gene: sequence homology with other human acute phase protein genes (1985)

We have determined the sequence coding for human alpha 1-acid glycoprotein from two independently isolated cDNA clones and a genomic clone. The aminoacid sequences deduced from the three clones, deriving from three different individuals, are identical. Southern blot analysis on human DNA indicates that there are at least two genes coding for alpha 1-AGP. We propose that alpha 1-AGP found in plasma is a mixture of the products of these two different genes. This is the simpler explanation for the heterogeneity in the aminoacid composition in purified alpha 1-AGP observed by Schmid et al. (1). DNA sequence comparison with cDNA clones coding for human alpha 1-antitrypsin and haptoglobin shows a conserved sequence within the 5' untranslated region which may play a role in the acute phase response.
