Timed revocation of user data (2012)

The way we deal with information has changed significantly over the last years. More and more private data is published on the Internet, and at the same time our capacity to store and process data has vastly increased. Systems to prevent a large-scale data collection by placing an "expiration date" on digital data have been proposed before, but either they only support very short expiration times of a few days (such as Vanish and EphPub), or they require additional infrastructure (such as FaceCloak and X-pire).
DIDS (distributed intrusion detection system)—motivation, architecture, and an early prototype (1997)

Intrusion detection is the problem of identifying unauthorized use, misuse, and abuse of computer systems by both system insiders and external penetrators. The proliferation of heterogeneous computer networks provides additional implications for the intrusion detection problem. Namely, the increased connectivity of computer systems gives greater access to outsiders, and makes it easier for intruders to avoid detection. IDS&apos;s are based on the belief that an intruder&apos;s behavior will be noticeably different from that of a legitimate user. We are designing and implementing a prototype Distributed Intrusion Detection System (DIDS) that combines distributed monitoring and data reduction (through individual host and LAN monitors) with centralized data analysis (through the DIDS director) to monitor a heterogeneous network of computers. This approach is unique among current IDS&apos;s. A main problem considered in this paper is the Network -user Identification problem, which is concerned ...
Haem O can replace haem A in the active site of cytochrome <i>c</i> oxidase from thermophilic bacterium PS3 (1991)

Thermophilic bacterium PS3 cultured under slightly air-limited conditions showed a mitochondrion-like cytochrome pattern similar to that in vigorously aerated cells, but an o-type cytochrome replaced cytochrome a3 as the CO-binding centre. Cytochrome cao-type oxidase was purified from the cell membranes by almost the same procedure as used for cytochrome caa3. The turnover number of cytochrome cao was higher than that of cytochrome caa3, but the Km's of the two enzymes for cytochrome c and O2 were almost the same. Gel electrophoresis in the presence of sodium dodecyl sulfate gave bands of four subunits at the identical positions both for cytochrome cao and cytochrome caa3. Cytochrome cao contained a novel kind of haem in addition to haems C and A. This novel haem is likely to be haem O, very recently found as the chromophore of the cytochrome bo complex in Escherichia coli. These data suggest that cytochrome cao is an alternative form of cytochrome c oxidase (cytochrome caa3), in which the cytochrome a3 centre of the enzyme is replaced with cytochrome o.
Next-generation seismic experiments: wide-angle, multi-azimuth, three-dimensional, full-waveform inversion (2013)

Full-waveform inversion (FWI) is an advanced seismic imaging technique that has recently become computationally feasible in three dimensions, and that is being widely adopted and applied by the oil and gas industry. Here we explore the potential for 3-D FWI, when combined with appropriate marine seismic acquisition, to recover high-resolution high-fidelity P-wave velocity models for subsedimentary targets within the crystalline crust and uppermost mantle. We demonstrate that FWI is able to recover detailed 3-D structural information within a radially faulted dome using a field data set acquired with a standard 3-D petroleum-industry marine acquisition system. Acquiring low-frequency seismic data is important for successful FWI; we show that current acquisition techniques can routinely acquire field data from airguns at frequencies as low as 2 Hz, and that 1 Hz acquisition is likely to be achievable using oceanbottom hydrophones in deep water. Using existing geological and geophysical models, we construct P-wave velocity models over three potential subsedimentary targets: the Soufrire Hills Volcano on Montserrat and its associated crustal magmatic system, the crust and uppermost mantle across the continent-ocean transition beneath the Campos Basin offshore Brazil, and the oceanic crust and uppermost mantle beneath the East Pacific Rise mid-ocean ridge. We use these models to generate realistic multi-azimuth 3-D synthetic seismic data, and attempt to invert these data to recover the original models. We explore resolution and accuracy, sensitivity to noise and acquisition geometry, ability to invert elastic data using acoustic inversion codes, and the trade-off between low frequencies and starting velocity model accuracy. We show that FWI applied to multi-azimuth, refracted, wide-angle, low-frequency data can resolve features in the deep crust and uppermost mantle on scales that are significantly better than can be achieved by any other geophysical technique, and that these results can be obtained using relatively small numbers (60-90) of ocean-bottom receivers combined with large numbers of airgun shots. We demonstrate that multi-azimuth 3-D FWI is robust in the presence of noise, that acoustic FWI can invert elastic data successfully, and that the typical errors to be expected in starting models derived using traveltimes will not be problematic for FWI given appropriately designed acquisition. FWI is a rapidly maturing technology; its transfer from the petroleum sector to tackle a much broader range of targets now appears to be entirely achievable.
Laser crystallization of silicon for high-performance thin-film transistors (2000)

We crystallize amorphous silicon films by a frequency doubled Nd:YVO4 laser with a pulse energy of 18.5 µJ and a repetition frequency of 20 kHz. A sequential lateral solidification process yields polycrystalline silicon with grains longer than the channel of thin-film transistors. The resulting electron field effect mobility of 410 cm2 V-1 s-1 shows the superiority of our process compared with excimer laser crystallization. A calculation results in a possible throughput of 35 cm2 s-1 for our laser crystallization process if one used a laser with a pulse energy of 1.25 mJ and a repetition frequency of 100 kHz.
A conditional form of Bruton's tyrosine kinase is sufficient to activate multiple downstream signaling pathways via PLC Gamma 2 in B cells (2001)

These data suggest that Btk:ER regulates downstream signaling pathways primarily via PLCgamma2 in B cells. While it is not known whether activated Btk:ER precisely mimics activated Btk, this conditional system will likely facilitate the dissection of the role of Btk and its family members in a variety of biological processes in many different cell types.
The complete V domain amino acid sequences of two myeloma inulin-binding proteins. (1982)

The myeloma proteins binding inulin afford a unique opportunity to study the V region patterns of variation because of the similarity in the VL as well as the VH regions. The diversity patterns in both the VL and VH regions suggest these proteins are encoded by multiple, very similar V gene segments or that somatic mutation may repeatedly generate identical variants. Because of the close similarity in the V domains of these proteins and the extensive idiotypic analyses that have been carried out previously, several interesting conclusions can be drawn about the nature of idiotypic determinants. First, a single amino acid residue may be involved in determining multiple idiotypic determinants. Second, hapten-inhibitable idiotypes may depend on residues within and outside the hypervariable regions. Third, idiotypic similarity does not always predict a corresponding sequence similarity.
Recommendation systems: Principles, methods and evaluation (2015)

On the Internet, where the number of choices is overwhelming, there is need to filter, prioritize and efficiently deliver relevant information in order to alleviate the problem of information overload, which has created a potential problem to many Internet users. Recommender systems solve this problem by searching through large volume of dynamically generated information to provide users with personalized content and services. This paper explores the different characteristics and potentials of different prediction techniques in recommendation systems in order to serve as a compass for research and practice in the field of recommendation systems.
Non toxic additives for improved fabric filter performance (1995)

The overall objective of this three-phase Small Business innovative Research (SBIR) program funded by the Department of Energy pittsburgh Energy Technology Center (PETC) is to commercialize a technology based upon the use of non-toxic, novel flue gas conditioning agents to improve particulate air toxic control and overall fabric filter performance. The ultimate objective of the Phase II program currently in progress is to demonstrate that the candidate additives are successful at full-scale on flue gas from a coal-fired utility boiler. This paper covers bench-scale field tests conducted during the period February through May, 1995. The bench-scale additives testing was conducted on a flue gas slipstream taken upstream of the existing particulate control device at a utility power plant firing a Texas lignite coal. These tests were preceded by extensive testing with additives in the laboratory using a simulated flue gas stream and re-dispersed flyash from the same power plant. The bench-scale field testing was undertaken to demonstrate the performance with actual flue gas of the bet candidate additives previously identified in the laboratory. Results from the bench-scale tests will be used to establish operating parameters for a larger-scale demonstration on either a single baghouse compartment or a full baghouse at more » the same site. « less
The Neuroprotective Effects of Oxaloacetate in Closed Head Injury in Rats is Mediated by its Blood Glutamate Scavenging Activity (2009)

The results of this study demonstrate that the primary mechanism by which oxaloacetate provides neuroprotective activity after CHI is related to its blood glutamate scavenging activity. Management of blood glutamate concentration may have important implications in the treatment of acute brain conditions, including CHI and stroke.

NOX2 deficiency alters macrophage phenotype through an IL-10/STAT3 dependent mechanism: implications for traumatic brain injury (2017)

These studies indicate that following TBI NOX2 inhibition promotes a robust anti-inflammatory response in macrophages/microglia that is mediated by the IL-10/STAT3 signaling pathway. Thus, therapeutic interventions that inhibit macrophage/microglial NOX2 activity may improve TBI outcomes by not only limiting pro-inflammatory neurotoxic responses, but also enhancing IL-10-mediated anti-inflammatory responses that are neuroprotective.
Implementation of low-complexity MIMO detector and efficient soft-output demapper for MIMO-OFDM-based wireless LAN systems (2013)

In this paper, we describe a simplified soft-output demapper designed to support coded multiple-input multiple-output orthogonal frequency-division multiplexing-based system utilizing only 3-bit soft information. The IEEE 802.11n standard requires relatively high punctured convolutional code rate of R=5/6 for spectrally efficient high-throughput data rate settings. In order to extract soft-bit information effectively without degrading the packet error rate performance, we introduce bit-rounding and effective-bit threshold adjustment techniques to achieve such.
Fast super-resolution reconstructions of mobile video using warped transforms and adaptive thresholding (2007)

Multimedia services for mobile phones are becoming increasingly popular thanks to capabilities brought about by location awareness, customized programming, interactivity, and portability. With mounting attraction to these services there is desire to seamlessly expand the mobile multimedia experience to stationary environments where high-resolution displays can offer significantly better viewing conditions. In this paper, we propose a fast, high quality super-resolution algorithm that enables high resolution display of low-resolution video. The proposed algorithm, SWAT, accomplishes sparse reconstructions using directionally warped transforms and spatially adaptive thresholding. Comparisons are made with some existing techniques in terms of PSNR and visual quality. Simulation examples show that SWAT significantly outperforms these techniques while staying within a limited computational complexity envelope.
Polyadenylated RNA sequences which are reduced in concentration following auxin treatment of soybean hypocotyls. (1980)

Previous work has shown that any effect of exogenous auxin on gene expression in soybean hypocotyl tissue must be restricted to a relatively small fraction of the polyadenylated RNA. However, kinetic hybridization analysis with cDNA probes revealed that a minor abundant class of sequences is markedly reduced in concentrations in the auxin-treated polyadenylated RNA. Recombinant plasmids containing copies of polyadenylated RNA species were constructed using the G-C tailing procedure and clones of auxin-regulated sequences were detected by differential in situ hybridization with cDNA of polyadenylated RNA from auxin-treated or untreated hypocotyls. Although the 12 clones which were selected all contained different size inserts, and were therefore independent, 11 of these apparently hybridized to just two different RNA species. The rate constant of the auxin-sensitive abundant component of the untreated polyadenylated RNA/DNA hybridization was similar to that of the reaction between the two major groups of clones and untreated polyadenylated RNA. This indicates that these cloned sequences are homologous with that cDNA fraction. The twelfth clone is thought to be representative of a group of less abundnt auxin-regulated polyadenylated mRNA species which had been detected in an earlier analysis of the in vitro translation products of soybean hypocotyl RNA. Both the timing and the extent of the influence of auxin on the relative concentration of these cloned sequences are quite consistent with a close relationship between growth regulation by auxin and its effects on gene expression.
A Polysilicon Field Effect Transistor Pressure Sensor of Thin Nitride Membrane Choking Effect of Right After Turn-on for Stress Sensitivity Improvement (2014)

We report a polysilicon active area membrane field effect transistor (PSAFET) pressure sensor for low stress deflection of membrane. The PSAFET was produced in conventional FET semiconductor fabrication and backside wet etching. The PSAFET located at the front side measured pressure change using 300 nm thin-nitride membrane when a membrane was slightly strained by the small deflection of membrane shape from backside with any physical force. The PSAFET showed high sensitivity around threshold voltage, because threshold voltage variation was composed of fractional function form in sensitivity equation of current variation. When gate voltage was biased close to threshold voltage, a fractional function form had infinite value at <TEX>$V_{tn}$</TEX>, which increased the current variation of sensitivity. Threshold voltage effect was dominant right after the PSAFET was turned on. Narrow transistor channel established by small current flow was choked because electron could barely cross drain-source electrodes. When gate voltage was far from threshold voltage, threshold voltage effect converged to zero in fractional form of threshold voltage variations and drain current change was mostly determined by mobility changes. As the PSAFET fabrication was compatible with a polysilicon FET in CMOS fabrication, it could be adapted in low pressure sensor and bio molecular sensor.
Arg15-Lys17-Arg18 turkey ovomucoid third domain inhibits human furin (1993)

Turkey ovomucoid third domain with Leu18 in its reactive site is a potent inhibitor of many serine proteinases: subtilisins, chymotrypsins, and elastases. Previous studies showed that an L18K mutation made it a moderately strong inhibitor of trypsin, while an L18E mutation made it a strong inhibitor of Glu-specific Streptomyces griseus proteinase (GluSGP). For human furin substrates the consensus optimal sequence is RXKR decreases. Therefore the A15R, T17K, and L18R mutations were made in turkey ovomucoid third domain. The mutant inhibits human furin with a Ka of 1.1 x 10(7) M-1. As human furin catalyzes an obligatory step in human immunodeficiency virus proliferation, this inhibitor, along with the others already available, deserves further study.
The effective feedback factor of self-balancing magnetic amplifiers (1958)

The effective feedback factor of a magnetic amplifier is a measure for the stability of operation (drift). In conventional forms of external-feedback or self-saturating circuits, the drift is linearly proportional to the actual value of ampere-turn gain. In these circuits, the drift can be reduced by reducing the extrinsic-feedback factor. However, because the ratio of gain reduction over drift reduction is constant, the gain will be reduced at the same rate.
Orthohydroxyhippuric (salicyluric) acid—its physiologic and clinical significance (1974)

Orthohydroxybenzoic acid was given the name salicylic acid because it was made in 1838 from a product of willow bark ( Salix alba ). About fifty years later salicylates became established as useful in the treatment of rheumatic fever. In the interval orthohydroxyhippuric acid was discovered and was named salicyluric acid . The fact that ingesting benzoic acid led to the excretion of hippuric acid led Bertagnini 10 in 1856 to look successfully for salicyluric acid in the urine after the ingestion of salicylate. For almost a hundred years thereafter orthohydroxyhippuric acid was thought of almost entirely as a metabolite of salicylate. A large amount of research was done on the formation and excretion of orthohydroxyhippuric acid in relation to salicylate therapy. Orthohydroxyhippuric acid also became important in the chemical industry, and much study has been devoted to its synthesis and its properties. 12 , 28
The (Pro)Renin Receptor (2009)

The (pro)renin receptor ([P]RR) is a transmembrane protein that binds both renin and prorenin with high affinity, increasing the catalytic cleavage of angiotensinogen and signaling intracellularly through mitogen-activated protein kinase activation. Although initially reported as having no homology with any known membrane protein, other studies have suggested that the (P)RR is an accessory protein, named ATP6ap2, that associates with the vacuolar H(+)-ATPase, a key mediator of final urinary acidification. Using in situ hybridization, immunohistochemistry, and electron microscopy, together with serial sections stained with nephron segment-specific markers, we found that (P)RR mRNA and protein were predominantly expressed in collecting ducts and in the distal nephron. Within collecting ducts, the (P)RR was most abundant in microvilli at the apical surface of A-type intercalated cells. Dual-staining immunofluorescence demonstrated colocalization of the (P)RR with the B1/2 subunit of the vacuolar H(+)-ATPase, the ion exchanger that secretes H(+) ions into the urinary space and that associates with an accessory subunit homologous to the (P)RR. In collecting duct/distal tubule lineage Madin-Darby canine kidney cells, extracellular signal-regulated kinase 1/2 phosphorylation, induced by either renin or prorenin, was attenuated by the selective vacuolar H(+)-ATPase inhibitor bafilomycin. The predominant expression of the (P)RR at the apex of acid-secreting cells in the collecting duct, along with its colocalization and homology with an accessory protein of the vacuolar H(+)-ATPase, suggests that the (P)RR may function primarily in distal nephron H(+) transport, recently noted to be, at least in part, an angiotensin II-dependent phenomenon.
