KinWrite: Handwriting-Based Authentication Using Kinect. (2013)

Password-based authentication is easy to use but its security is bounded by how much a user can remember. Biometrics-based authentication requires no memorization but ‘resetting ’ a biometric password may not always be possible. In this paper, we propose a user-friendly authentication system (KinWrite) that allows users to choose arbitrary, short and easy-to-memorize passwords while providing resilience to password cracking and password theft. KinWrite lets users write their passwords in 3D space and captures the handwriting motion using a low cost motion input sensing device—Kinect. The low resolution and noisy data captured by Kinect, combined with low consistency of in-space handwriting, have made it challenging to verify users. To overcome these challenges, we exploit the Dynamic Time Warping (DTW) algorithm to quantify similarities between handwritten passwords. Our experimental results involving 35 signatures from 18 subjects and a brute-force attacker have shown that KinWrite can achieve a 100 % precision and a 70 % recall (the worst case) for verifying honest users, encouraging us to carry out a much larger scale study towards designing a foolproof system. 1
Functional Assays of Protein C: Comparison of Two Snake-Venom Assays with Two Thrombin Assays (1988)

Protein C (PC) activities measured by two thrombin-based assays have been compared with those obtained by two assays based on snake venom activation of plasma PC followed by measurement of both the amidolytic and anticoagulant activities of activated PC. This study indicates that snake venom assays gave results similar to those of the thrombin assays in 20 healthy subjects, in 16 patients with DIC and in 15 patients with congenital PC deficiency. There was, however, some degree of misclassification of normals and congenitally-deficient patients, with only the clotting snake venom assay resulting in no misclassifications. In 15 patients stabilized on warfarin treatment and in 17 with liver disease, the clotting snake venom assay gave significantly lower values than the other assays, so that it might prove to be more sensitive than the other assays to these defects.
A 1.2- mu m CMOS current-controlled oscillator (1992)

A simple, fully symmetrical, current-controlled CMOS oscillator is presented. The oscillator uses two grounded capacitors. This 5-V architecture permits relatively large capacitor voltage amplitudes, thus minimizing jitter. The design also operates with power supply voltages as low as 3 V. Because there are no special capacitor requirements, the design is compatible with standard scaled digital CMOS processes. The use of a double differential latching comparator allows high-speed operation with good control linearity. The circuit was successfully fabricated using a 1.2- mu m CMOS process.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Higher radix aperiodic-convolution algorithms (1986)

Two alternative methods are proposed which can be used to derive efficient aperiodic-convolution algorithms for all filter lengths up to 36. A nesting technique is then described by which algorithms of this class can be used to derive efficient aperiodic-convolution algorithms for over 60 percent of the filter lengths in the range 37-1296. The computational complexity of the new algorithms is studied and formulas are derived for the required numbers of multiplications and additions. The contribution concludes with a comparison which clearly illustrates that the new methods lead to algorithms which are more efficient than algorithms based on the fast Fourier transform or rectangular transform for filter lengths up to 1296 for the case where the data block length is equal to the filter length.
Fixed- and movable-boundary channel-access schemes for integrated voice/data wireless networks (1995)

Addresses the major issues associated with channel access in integrated wireless networks, and proposes and analyzes the "wireless integrated multiple access" (WIMA) protocol. This scheme is based on a mixture of boundary ideas for integration and of previously introduced protocols for wireless access, and is well suited to either satellite or to terrestrial networks. A two-dimensional first-order Markov chain model for this scheme is presented, and techniques that exploit the structural properties of this chain to simplify the evaluation of the equilibrium state, without sacrificing accuracy, are described. Analytical models for the evaluation of data-packet delay for both fixed- and movable-boundary versions of this protocol and for voice-call blocking probability are presented. Performance results illustrate the dependence of performance on system parameters, and demonstrate the improved performance that can be achieved through the use of the movable-boundary version.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Renal Metabolism of the<i>β</i>-Subunit of Human Choriogonadotropin in the Rat (1986)

We analyzed the immunoreactive renal metabolites of the beta-subunit moieties of unlabeled highly purified hCG, hCG beta, and desialylated hCG (as-hCG) in rats by RIA and Sephadex G-100 chromatography. Infusions of hCG beta, as-hCG, or intact hCG resulted in accumulation in the kidney of a large quantity of small mol wt peptides lacking the immunological determinants of the carboxy-terminal peptide (CTP) of the beta-subunit. In the case of as-hCG, renal accumulation of these beta-core fragments was greatly enhanced when as-hCG binding to hepatic galactose receptors was inhibited by infusion of as-fetuin. The beta-core fragments in kidney had the same immunological and G-100 chromatographic characteristics as beta-core fragments in liver, suggesting similar intracellular catabolic mechanisms in these tissues. The kinetics of beta-core fragment turnover in kidney were studied after injection of hCG beta, which is cleared from the circulation within 1 h. Loss of beta CTP immunoreactivity was the initial event in hCB beta catabolism by the kidney; most of this process occurred between 7 and 30 min after injection. This was followed by a gradual reduction of the size of accumulated hCG beta metabolites over the next 60 min. The beta-core fragments that accumulated had a Kav of approximately 0.57 and a very slow degradation rate over the next 5 h (half-life greater than 6 h). Chromatographic analysis of urine obtained 6 h after beginning a continuous infusion of hCG, hCG beta, or as-hCG displayed in each case a major peak corresponding to the infused molecule, apparently intact, and a minor peak of beta CTP immunoreactivity of small mol wt. Relative to the beta CTP fragments apparent in urine, there were few beta-core fragments. These data indicate that separate fates exist for immunoreactive fragments generated by hCG beta metabolism in the rat kidney. One appears to be intracellular and similar to the liver pathway of as-hCG degradation in that it leads to the formation of long-lived beta-core fragments. The other takes place within ready access to the urinary compartment and leads to the accumulation in urine of beta-CTP fragments.
A systematic search for new mammalian noncoding RNAs indicates little conserved intergenic transcription (2005)

Since the sequence and expression of most known coding transcripts and functional ncRNAs is conserved between human and mouse, the lack of northern-detectable expression in human cells and tissues of the novel mouse and rat ncRNAs that we identified suggests that they are not functional or possibly have rodent-specific functions. Our results confirm that relatively little of the intergenic sequence conserved between human, mouse and rat is transcribed at high levels in mammalian tissues, possibly suggesting a limited role for transcribed intergenic and intronic sequences as independent functional elements.
DNA damage induction of ribonucleotide reductase. (1989)

RNR2 encodes the small subunit of ribonucleotide reductase, the enzyme that catalyzes the first step in the pathway for the production of deoxyribonucleotides needed for DNA synthesis. RNR2 is a member of a group of genes whose activities are cell cycle regulated and that are transcriptionally induced in response to the stress of DNA damage. An RNR2-lacZ fusion was used to further characterize the regulation of RNR2 and the pathway responsible for its response to DNA damage. beta-Galactosidase activity in yeast strains containing the RNR2-lacZ fusion was inducible in response to DNA-damaging agents (UV light, 4-nitroquinoline-1-oxide [4-NQO], and methyl methanesulfonate [MMS]) and agents that block DNA replication (hydroxyurea [HU] and methotrexate) but not heat shock. When MATa cells were arrested in G1 by alpha-factor, RNR2 mRNA was still inducible by DNA damage, indicating that the observed induction can occur outside of S phase. In addition, RNR2 induction was not blocked by the presence of cycloheximide and is therefore likely to be independent of protein synthesis. A mutation, rnr2-314, was found to confer hypersensitivity to HU and increased sensitivity to MMS. In rnr2-314 mutant strains, the DNA damage stress response was found to be partially constitutive as well as hypersensitive to induction by HU but not MMS. The induction properties of RNR2 were examined in a rad4-2 mutant background; in this genetic background, RNR2 was hypersensitive to induction by 4-NQO but not MMS. Induction of the RNR2-lacZ fusion in a RAD(+) strain in response to 4-NQO was not enhanced by the presence of an equal number of rad4-2 cells that lacked the fusion, implying that the DNA damage stress response in cell autonomous.
Detonation cell size measurements in high-temperature hydrogen-air-steam mixtures at the BNL high-temperature combustion facility (1997)

The High-Temperature Combustion Facility (HTCF) was designed and constructed with the objective of studying detonation phenomena in mixtures of hydrogen-air-steam at initially high temperatures. The central element of the HTCF is a 27-cm inner-diameter, 21.3-m long cylindrical test vessel capable of being heating to 700K {+-} 14K. A unique feature of the HTCF is the {open_quotes}diaphragmless{close_quotes} acetylene-oxygen gas driver which is used to initiate the detonation in the test gas. Cell size measurements have shown that for any hydrogen-air-steam mixture, increasing the initial mixture temperature, in the range of 300K to 650K, while maintaining the initial pressure of 0.1 MPa, decreases the cell size and thus makes the mixture more detonable. The effect of steam dilution on cell size was tested in stoichiometric and off-stoichiometric (e.g., equivalence ratio of 0.5) hydrogen-air mixtures. Increasing the steam dilution in hydrogen-air mixtures at 0.1 MPa initial pressure increases the cell size, irrespective of initial temperature. It is also observed that the desensitizing effect of steam diminished with increased initial temperature. A 1-dimensional, steady-state Zel`dovich, von Neumann, Doring (ZND) model, with full chemical kinetics, has been used to predict cell size for hydrogen-air-steam mixtures at different initial conditions. Qualitatively the model predicts the overall trends observed in the measured cell size versus mixture composition and initial temperature and pressure. It was found that the proportionality constant used to predict detonation cell size from the calculated ZND model reaction zone varies between 10 and 100 depending on the mixture composition and initial temperature. 32 refs., 35 figs.

Economical <i>RC</i> active lossy ladder filters (1973)

The letter describes a class of RC active filters derived from RLC lossy ladder-filter prototypes. The presence of loss in the prototypes allows the use of active building blocks containing only one amplifier. Design methods are outlined, and ways of reducing sensitivity are discussed. The filters are economical in the number of amplifiers required, and a comparison indicates that they can be significantly less sensitive than active filters built as a cascade of non-interacting sections.
EPIDEMIOLOGY OF CANINE HEARTWORM INFECTION (1983)

Factors affecting transmission of D. immitis between dogs are summarized in table 4. Although this list may not be exhaustive, it illustrates the complexity of heartworm epidemiology. There are interesting and provocative similarities in the epidemiology of canine and human filariasis. Ottesen (148) has described the spectrum of disease observed in regions endemic for lymphatic filariasis. It includes patients with 1) microfilariae, but no symptoms; 2) disease, but no microfilariae; 3) tropical pulmonary eosinophilia of filarial etiology; and 4) no disease and no evidence of infection. A dog population in areas endemic for D. immitis may show a similar range of clinical manifestations. For example, dogs with microfilariae may not demonstrate clinical disease; dogs with occult infection may show signs ranging from none to severe, including signs similar to the human tropical pulmonary eosinophilia syndrome. Although some dogs live in endemic areas and, apparently, are not infected, it is difficult to determine whether those dogs are resistant to infection or if they have not had adequate exposure. One study has explored the relationship between human W. bancrofti infection and genetic factors (149). Although familial clustering of cases was apparent, the authors were unable to distinguish with certainty whether this association was due to environmental or genetic influences. Carefully designed seroepidemiologic studies of canine heartworm infection may shed some light on genetic or other factors which confer resistance or susceptibility to filarial infections. Natural strain variation has been recognized in several filariae of medical importance including O. volvulus (150), B. malayi (151), and L. loa (2). Strain variation may be manifested as differences in behavior patterns such as microfilarial periodicity, vector and host affinities, and pathogenicity. A laboratory study (88) demonstrated how such strains could arise. In this study, a strain of Brugia patei was adapted to a new, normally refractory host, by artificial selection. The possible existence of different physiologic races of D. immitis should be investigated. Experimental infections with D. immitis have been achieved under laboratory conditions in numerous mosquito species (77).(ABSTRACT TRUNCATED AT 400 WORDS)
Asymptotic waveform evaluation for timing analysis (1990)

Asymptotic waveform evaluation (AWE) provides a generalized approach to linear RLC circuit response approximations. The RLC interconnect model may contain floating capacitors, grounded resistors, inductors, and even linear controlled sources. The transient portion of the response is approximated by matching the initial boundary conditions and the first 2q-1 moments of the exact response to a lower-order q-pole model. For the case of an RC tree model, a first-order AWE approximation reduces to the RC tree methods.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Neutrophil Activation by Helicobacter pylori Lipopolysaccharides (1994)

Helicobacter pylori-induced release of toxic substances by neutrophils could be of potential importance in the pathogenesis of gastroduodenal inflammatory diseases. Lipopolysaccharide (LPS) has the ability to induce neutrophil activation at very low concentrations. Neutrophil oxidative metabolism and enzyme release were assessed after stimulation of neutrophils with various preparations of LPS from H. pylori and compared with that obtained with Salmonella typhimurium LPS. No direct activation of neutrophils by LPS was observed. Preincubation with LPS showed a significant priming for increased activity on subsequent stimulation, particularly with rough-form LPS. The potency of H. pylori LPS was 10-fold lower than that of S. typhimurium LPS, probably reflecting the unique biochemical structure of H. pylori LPS. Chronic low-grade stimulation by H. pylori LPS in the gastric mucosa may render neutrophils primed for the excessive release of detrimental substances into the tissue on stimulation by other mediators.
Automatically Validating Model Consistency during Refinement (2000)

Automated consistency checking between software development models still remains a complex and non-scalable problem. Current solutions are frequently only able to detect small numbers of inconsistency types, often under less than realistic assumptions. This paper introduces a new approach to consistency checking based on model transformation. Our approach uses transformation to translate and to interpret model information between different types of views (e.g., diagrams) in order to simplify their comparison. Transformation-based consistency checking, in the manner we use it, has never been attempted before and, as this paper will demonstrate, has significant benefits including (1) increased variety of automatically detectable inconsistencies, (2) improved scalability, (3) ability to handle incomplete, ambiguous model specifications, and (4) ability to define domain- and model-independent inconsistency rules. This paper will illustrate our approach in context of model refinement and abstraction using a complex example. Our approach is fully tool supported.
Gonadotropin-Releasing Hormone Blockers and Cardiovascular Disease Risk: Analysis of Prospective Clinical Trials of Degarelix (2011)

In men with prostate cancer observed rates of cardiovascular disease events were similar before and after degarelix treatment. Events were largely confined to men with preexisting cardiovascular disease and further modulated by age and modifiable risk factors. Randomized, controlled trials and longer followup are key to fully clarify the comparative safety of gonadotropin-releasing hormone antagonists vs agonists.
Interleukin-18 as an efficient marker for remission and follow-up in patients with inactive adult-onset Still’s disease (2013)

IL-18 might be an efficient marker for diagnosis and follow-up of AOSD and might also be a useful predictor of remission, especially in clinically inactive patients.
Calculation of three-dimensional transonic turbine cascade flow (1992)

A computer code has been applied to inviscid and viscous flows through a linear turbine cascade operating in the transonic flow regime. The Euler and Navier-Stokes equations are solved by an explicit finite-volume time-stepping procedure based on the method of Jameson et al. for the integration of the Euler equations and extended to Navier-Stokes equations by Schwamborn. The inviscid and viscous results in two-dimensions represent the profile characteristics at midspan position and the three-dimensional, viscous results include sidewall effects. A particular consideration of the flow losses gives detailed information about secondary flow behavior. The computational results are compared to experimental data for the MTU-T5.1 profile at isentropic outflow Mach numbers of 0.7, 0.9, and 1.1.
Mild acidosis delays hypoxic spreading depression and improves neuronal recovery in hippocampal slices (1994)

Severe tissue acidosis has been viewed traditionally as a damaging component of cerebral hypoxia. However, a neuroprotective action of low pH during hypoxia has been described in primary neuronal cultures. To identify and characterize this effect in mature brain tissue, adult rat hippocampal slices were made hypoxic after adjusting pHo with HCl or NaOH. Ion-selective microelectrodes were positioned in CA1 to record evoked field potentials, extracellular DC voltage (Vo), pHo, and [Ca2+]o. Orthodromic population spike amplitude was used as a measure of slice recovery 2 hr after reoxygenation. All slices became markedly acidotic during hypoxia (delta pHo approximately 0.4 pH unit). Following restoration of O2 and bath pH to 7.4, slice pHo returned to its pretreatment level regardless of experimental treatment, hypoxic duration, or the degree of electrophysiological recovery. When either the period of hypoxia or the duration of HSD was held constant, acid-treated slices exhibited a significant improvement in recovery. However, in neither paradigm did the recovery of alkaline-treated slices differ from controls. Mild acidosis (bath pH = 6.9-7.3) caused a reversible depression of the orthodromic population spike, an increase in the latency of hypoxic spreading depression-like depolarization (HSD), and a decrease in the magnitude of the associated negative Vo shift. For each of these parameters, mild alkalinity (bath pH = 7.7) had the opposite effect. Acid treatment did not affect the decrease in [Ca2+]o during HSD but accelerated its recovery after reoxygenation. These results suggest that mild acidosis may limit hypoxic neuronal injury in vitro by delaying HSD onset and by additional mechanisms unrelated to the degree of calcium influx during neuronal depolarization.
An Atlas of Selected Multi-Frequency Radio Bursts from the Twentieth Solar Cycle. (1980)

Illustrations or reconstructions of the analog records of significant and interesting solar radio bursts observed during Solar Cycle 20 at the AFGL Sagamore Hill Radio Observatory in Hamilton, Massachusetts, and the Manila Observatory in the Philippines are presented. Many of the illustrated burst records were associated with the emission of energetic solar protons and subsequent disturbances to the ionosphere and the geomagnetic field. (Author)
The effect of Mo back contact on Na out-diffusion and device performance of Mo/Cu(In,Ga)Se/sub 2//CdS/ZnO solar cells (2003)

Molybdenum thin films were deposited on soda lime glass (SLG) substrates using direct-current planar magnetron sputtering, with a sputtering power density of 1.2 W/cm/sup 2/. The working gas (Ar) pressure was varied from 0.6 to 16 mtorr to induce changes in the Mo films' morphology and microstructure. Thin films of Cu(In,Ga)Se/sub 2/ (CIGS) were deposited on the Mo-coated glass using the 3-stage co-evaporation process. The morphology of both the Mo-coated SLG and the CIGS thin films grown on it was examined using high-resolution scanning electron microscopy. Na was depth profiled in the Mo and CIGS films by secondary ion mass spectrometry. The device performance was evaluated under standard conditions of 1000 W/m/sup 2/ and 25/spl deg/C. Optimum device performance is found for an intermediate Mo sputtering pressure.
