Digging into HTTPS (2010)

Recently, webmail interfaces, e.g., Horde, Outlook Web Access, and webmail platforms such as GMail, Yahoo!, and Hotmail have seen a tremendous boost in popularity. Given the importance of e-mail for personal and business use alike, and its exposure to imminent threats, there exists the need for a comprehensive view of the Internet mail system, including webmail traffic. We, in this paper, propose a novel, passive approach to identify webmail traffic solely based on network-level data in order to obtain a comprehensive view of the mail system. Key to our approach is that we leverage correlations across protocols and time to introduce three novel features for HTTPS webmail classification. Our first feature is based on the finding that webmail servers tend to reside close to legacy mail servers, e.g. IMAP and POP, which can be easily identified. Our second feature leverages that the usage of webmail services results in distinct patterns on sessions' duration and on the diurnal/weekly traffic usage profile. In addition, our third feature exploits the observation that traffic flows to webmail platforms exhibit inherent periodicities due to the fact that AJAX-based clients periodically check for new messages. We use these three features to build a simple classifier and detect webmail traffic on real-world NetFlow traces from a medium-sized backbone network. We believe that the major contribution of this paper -- exploring a set of new features that could classify applications that run over HTTPS ports solely based on NetFlow data -- will stimulate more general advance in the field of traffic classification.

Kalman filter analysis of precision clocks with real-time parameter estimation (2003)

An optimum algorithm has been developed for estimating the time, frequency, and frequency aging of clocks and oscillators while simultaneously estimating the noise spectrum. The algorithm is sufficiently general to be used with all types of quartz oscillators and atomic clocks yet the approach is appropriate for use with an embedded controller in automated systems intended for field applications. The technique is adaptive-it calculates and updates estimates for all required clock parameters as observations occur. Data are accepted whenever available and are not required to be at fixed multiples of a fixed sampling time. Only coarse estimates of the parameters are required to initialize the computation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
PAR-4 Agonist AYPGKF Stimulates Thromboxane Production by Human Platelets (2002)

Previous reports have indicated that thrombin-induced thromboxane production by human platelets occurs through two types of interaction between thrombin and the platelet surface. One of these interactions is with protease activated receptor(PAR)-1, the first identified thrombin receptor. These studies were undertaken to determine whether stimulation of PAR-4 also results in thromboxane production. The results show that treatment of washed human platelets with the PAR-4 agonist AYPGKF stimulates a maximum of 40% to 60% of the thromboxane produced by 100 nmol/L thrombin. Maximal thromboxane production requires approximately 1.0 mmol/L AYPGKF, despite the observation that maximal aggregation is produced by 45 micromol/L AYPGKF. Thromboxane produced by the combined stimulation of PAR-1 and PAR-4 is additive. Pretreatment of platelets with 45 micromol/L AYPGKF partially desensitizes thromboxane production in response to higher concentrations of AYPGKF and thrombin but not to stimulation by SFLLRN. PAR-4-induced stimulation is also significantly inhibited by 60 micromol/L genistein. It is concluded that activation through either PAR-1 or PAR-4 results in thromboxane production, but that stimulation of neither receptor alone produces thromboxane equivalent to that produced by 100 nmol/L thrombin. Thus, these findings demonstrate the presence of two pathways for thrombin-induced thromboxane production by platelets as proposed previously.
Reversal of postischemic acute renal failure with a selective endothelinA receptor antagonist in the rat. (1994)

Studies were designed to examine the effect of a selective endothelinA (ETA) receptor antagonist, BQ123, on severe postischemic acute renal failure (ARF) in Sprague-Dawley rats. Severe ARF was induced in uninephectomized, chronically instrumented rats by 45-min renal artery occlusion. BQ123 (0.1 mg/kg.min) or vehicle was infused intravenously for 3 h on the day after ischemia. Measurements before infusion (24 h control) showed a 98% decrease in glomerular filtration rate (GFR), increase in fractional excretion of sodium from 0.6 to 39%, and in plasma K+ from 4.3 to 6.5 mEq/liter. All vehicle-treated rats died in 4 d because of continuous deterioration of renal function, resulting in an increase of plasma K+ to fatal levels (> 8 mEq/liter). Infusion of BQ123 significantly improved survival rate (75%) by markedly improving tubular reabsorption of Na+ and moderately increasing GFR and K+ excretion. Plasma K+ returned to basal levels by the 5th d after ischemia. Improved tubular function was followed by gradual recovery in GFR and urinary concentrating mechanism. Additional data from renal clearance studies in rats with moderate ARF (30-min ischemia) and in normal rats with intact kidneys showed that ETA receptor blockade increases Na+ reabsorption and has no effect on renal hemodynamics. These results indicate that in the rat, the ETA receptor subtype mediates tubular epithelial function, and it plays a significant role in the pathogenesis of ischemia-induced ARF. Treatment with the selective ETA receptor antagonist reverses deteriorating tubular function in established ARF, an effect of possible therapeutic significance.
Beneficial effect of catalase treatment on growth of Clostridium perfringens (1976)

Several common plating media were tested for their ability to support growth of Clostridium perfringens after storage of the plates for 1 to 10 days at 4 and 25 degrees C with and without subsequent addition of catalase. Liver-veal (LV) agar and brain heart infusion (BHI) agar quickly become incapable of supporting growth after storage without added catalase, whereas Shahidi Ferguson perfringens (SFP) agar and Brewer anaerobic (BA) agar were less affected. Plate counts of C. perfringens on untreated LV and BHI agars stored 3 days at 25 degrees C showed a reduction of 98.2%, whereas counts on SFP and BA agars were reduced by 13.6% and 46.2%, respectively. Addition of 1,500 U of beef liver catalase to the surface of the 3-day-old agars before incubation resulted in substantial restoration of their growth-promoting ability. Counts of colonies on LV, GHI, SFP, and BA agars with added catalase were usually 20 to 90% higher than untreated controls. Similar results were obtained using purified catalase, fungal catalase, and horseradish peroxidase. These results suggest that inhibition may be due to peroxide formed during storage and incubation and that additon of catalase provides near optimum conditions for growth of C. perfringens on these media.
DIFFUSER ANGLE CONTROL TO AVOID FLOW SEPARATION (2014)

Diffusers are extensively used in centrifugal compressors, axial flow compressors, ram jets, combustion chambers, inlet portions of jet engines and etc. A small change in pressure recovery can increases the efficiency significantly. Therefore diffusers are absolutely essential for good turbo machinery performance. The geometric limitations in aircraft applications where the diffusers need to be specially designed so as to achieve maximum pressure recovery and avoiding flow separation. The study behind the investigation of flow separation in a planar diffuser by varying the diffuser taper angle for axisymmetric expansion. Numerical solution of 2D axisymmetric diffuser model is validated for skin friction coefficient and pressure coefficient along upper and bottom wall surfaces with the experimental results of planar diffuser predicted by Vance Dippold and Nicholas J. Georgiadis in NASA research center (2) .
A randomized double-blind trial of oral ketamine versus placebo in cancer-related neuropathic pain (2018)

A randomised trial shows that oral ketamine is no more effective than placebo in cancer related-neuropathic pain.
k-IOS: Intersection of spheres for efficient proximity query (2012)

We present a new bounding volume structure, k-IOS that is an intersection of k spheres, for accelerating proximity query including collision detection and Euclidean distance computation between arbitrary polygon-soup models that undergo rigid motion. Our new bounding volume is easy to implement and highly efficient both for its construction and runtime query. In our experiments, we have observed up to 4.0 times performance improvement of proximity query compared to an existing well-known algorithm based on swept sphere volume (SSV) [1]. Moreover, k-IOS is strictly convex that can guarantee a continuous gradient of distance function with respect to object's configuration parameter.
The Emulsifying Properties of Commercial Milk Protein Products in Simple Oil‐in‐Water Emulsions and in a Model Food System (2000)

ABSTRACT: The emulsifying properties of six commercial milk protein products were studied. The products were separated into one of two groups depending on whether they contained aggregated (micellar) casein or disordered protein (casein or whey protein). Disordered proteins had a greater emulsifying ability than aggregated proteins. Dispersion of aggregated protein in dissociating buffer improved the emulsifying ability. Comparison of emulsion properties in simple oil‐in‐water emulsions with those in a model coffee whitener formulation showed that the lower emulsifying ability of aggregated protein could be partially compensated by other ingredients.
THE PREPARATION AND PROPERTIES OF UROGASTRONE<sup>1</sup> (1942)

UROGASTRONE is a watersoluble substance, obtainable from the urine of both dogII I and man, which effectively inhibits gastric secretion (1, 2, 3). Its physiological rôle has not been elucidated as yet, but in the course of preparing and assaying several hundred preparations of urogastrone, some information regarding its chemical and physiological properties has been obtained. It is the purpose of this report to communicate these findings and to describe methods for obtaining the principle in highly potent form. Crude concentrate. The urine is collected in 5gallon bottles containing sufficient preservative to maintain sterility when the bottle has become filled. In the case of tricresol a concentration of 0.25‰ is used; with phenol, a concentration of 0.5‰, with toluene, enough is used to cover the surface. If the latter preservative has been used, the urine without stirring is siphoned off to separate it from the toluene,
Identification of a novel selective and potent inhibitor of glycogen synthase kinase-3 (2019)

Glycogen synthase kinase-3 (GSK-3) is a multitasking protein kinase that regulates numerous critical cellular functions. Not surprisingly, elevated GSK-3 activity has been implicated in a host of diseases including pathological inflammation, diabetes, cancer, arthritis, asthma, bipolar disorder, and Alzheimer's. Therefore, reagents that inhibit GSK-3 activity provide a means to investigate the role of GSK-3 in cellular physiology and pathophysiology and could become valuable therapeutics. Finding a potent inhibitor of GSK-3 that can selectively target this kinase, among over 500 protein kinases in the human genome, is a significant challenge. Thus there remains a critical need for the identification of selective inhibitors of GSK-3. In this work, we introduce a novel small organic compound, namely COB-187, which exhibits potent and highly selective inhibition of GSK-3. Specifically, this study <i>1</i>) utilized a molecular screen of 414 kinase assays, representing 404 unique kinases, to reveal that COB-187 is a highly potent and selective inhibitor of GSK-3; <i>2</i>) utilized a cellular assay to reveal that COB-187 decreases the phosphorylation of canonical GSK-3 substrates indicating that COB-187 inhibits cellular GSK-3 activity; and <i>3</i>) reveals that a close isomer of COB-187 is also a selective and potent inhibitor of GSK-3. Taken together, these results demonstrate that we have discovered a region of chemical design space that contains novel GSK-3 inhibitors. These inhibitors will help to elucidate the intricate function of GSK-3 and can serve as a starting point for the development of potential therapeutics for diseases that involve aberrant GSK-3 activity.
CMOS wide-swing differential VCO for fully integrated fast PLL (2002)

Presents a fully integrated CMOS fast phase locked loop (PLL), based on a new wide swing differential voltage controlled oscillator (WSDVCO). The proposed PLL incorporates new simple architecture of well known PLL building blocks (a dynamic phase-frequency detector, a charge pump, an on-chip low-pass filter, a WSDVCO and a frequency divider). The present version of the WSDVCO allows one to obtain wide tuning range of 40 to 730 MHz simulated with Spectre simulator using 0.25 /spl mu/m CMOS technology. The simplicity of the proposed PLL building blocks permits one to design high performance PLL.
Efficiency calculations of thin-film GaAs solar cells on Si substrates (1985)

Dislocation effect upon the efficiency of single-crystal thin-film AlGaAs-GaAs heteroface solar cells on Si substrates is analyzed. Solar-cell properties are calculated based on a simple model; in the model, dislocations act as recombination centers to reduce the minority-carrier diffusion length in each layer and increase the space-charge layer recombination current. Numerical analysis is also carried out to optimize thin-film AlGaAs-GaAs heteroface solar-cell structures. The fabrication of thin-film AlGaAs-GaAs heteroface solar cells with a practical efficiency larger than 18% on Si substrates appears possible if the dislocation density in the thin-film GaAs layer is less than 106 cm−2.
Name-It: naming and detecting faces in news videos (1999)

We developed Name-It, a system that associates faces and names in news videos. It processes information from the videos and can infer possible name candidates for a given face or locate a face in news videos by name. To accomplish this task, the system takes a multimodal video analysis approach: face sequence extraction and similarity evaluation from videos, name extraction from transcripts, and video-caption recognition.
Lighthead robotic face (2011)

This video is about a new kind of robotic head. Through back-projection of a computer generated video into a half-translucent mask, the LightHead robotic head has many advantages compared to tradition mechatronic robotic faces. These advantages are most notably the versatility and ease of controlling facial expressions and creating new faces, the total weight and the low costs. By mounting the head on a robotic arm and equipping it with face detection software, the robot can interact with people in a natural manner.
Optoelectronic router in glass waveguide with a liquid crystal cladding (2003)

An optoelectronic router integrated in a sol-gel waveguide with a liquid crystal over-layer, working at the wavelength of 1.55 μm, is theoretically discussed. Mode-mixing principle and electro-optic effect of a <i>smectic A</i>* liquid crystal have been employed to reach the optical shift between two output waveguides. The device is composed by: a single mode input optical channel waveguide; a bimodal active region, having a liquid crystal as over-layer; an output Y branch. The active region is designed to allow a π shift between the two supported modes, by means of electro-optic effect of smectic A*. By doing so it is possible to steer light from one output channel to the other one of output Y.
Computation of modifier scope in NP by a language-neutral method (2002)

The relative logical scope of multiple modifiers within NP is often semantically significant. This paper proposes a structurally based method for computing the relative scope of such modifiers, based on their order, type, and syntactic complexity. The algorithm is language-neutral, in that it works with minimal errors for a wide range of languages without language-specific stipulations.
CVD diamond-based semi-transparent beam-position monitors for synchrotron beamlines: preliminary studies and device developments at CEA/Saclay (2006)

Polycrystalline diamond synthesized using the chemical vapour deposition (CVD) technique can be used to fabricate new types of photodetectors for the characterization of X-ray light in synchrotron beamlines. Since diamond exhibits a low absorption to low-energy photons, such devices allow beam-position monitoring with very little beam attenuation at photon energies as low as 2 keV up to 15-20 keV. Here it is shown how diamond-based devices can simply be processed as ionization chambers for advanced semi-transparent position monitoring with high position resolution (<2 microm). Other configurations using the same principle can also enable in-line field profiling. It is also shown what can be expected from these devices in terms of performances, signal-to-noise ratios and reliability, together with their inherent limitations caused by the presence of defects in polycrystalline materials. In particular, diamond devices with extremely low carrier lifetimes, owing to quenched transport properties, could also be of particular interest for the characterization of the temporal structure of synchrotron light. Interest in these devices lies in the permanent insertion into beamlines and withstanding high levels of radiation for continuous beam monitoring.
Fatty acid compositions of tigernut tubers (<i>Cyperus esculentus</i> L.), baobab seeds (<i>Adansonia digitata</i> L.), and their mixture (1996)

Abstract Fatty acid profiles and iodine values of tigernut tubers ( Cyperus esculentus L.), decorticated seeds of the baobab tree ( Adansonia digitata L.), and their mixture (one part of tigernut to three parts of baobab seeds, w/w) were chromatographically and chemically determined. All three samples contained myristic acid as the main saturated acid and oleic acid as the predominant unsaturated acid. Linoleic acid was present in the samples to the extent of 8.8–27.4%, and no other polyunsaturated acids were found. The vegetable oil mixture had the highest level of linoleate, and its possible significance in relation to the intended use in novel food formulation is discussed.

Mechanism of regression of mammary adenocarcinomas in rats following plasma adsorption over protein A-containing Staphylococcus aureus. (1982)

The plasma from 7,12-dimethylbenz(a)anthracene-induced mammary tumor-bearing rats was adsorbed ex vivo with nonviable protein A-containing Staphylococcus aureus Cowan I and then injected into the rats, along with its original blood cells. Tumors in the treated rats showed significant (p less than 0.005) growth inhibition. There were fewer metastatic nodules; cellular cytotoxicity in the presence of plasma was augmented, and there was increased antitumor cytotoxic antibody activity in treated rats. Plasma from sham-treated rats, however, showed blocking activity. It appears that plasma perfusion over S. aureus decreases blocking activity and augments antitumor immunoreactivity of plasma. The exact mechanism by which growth of 7,12-dimethylbenz(a)anthracene-induced mammary tumors was inhibited in these treated Sprague-Dawley rats is not known. However, it is hypothesized that the observed tumor regression is at least partly attributable to the augmentation of antitumor immunoreactivity in the treated animals.
Use of an Optimized 1,2‐Indanedione Process for the Development of Latent Prints* (2008)

1,2-Indanedione belongs to a class of compounds which have demonstrated great potential in the processing of latent prints, particularly in the area of fluorescence. However, variability in results achieved worldwide has precluded it from being used extensively. In order to isolate the cause of this variability, various components of the formulation were analyzed, including purity level of the indanedione, type of carrier solvent, and the use of ZnCl(2) both as a secondary application and incorporated into the reagent. Using a resultant optimized formulation (Ind-Zn), performance comparisons were then made in the areas of visible color development, fluorescence, and degree of substrate staining with those of 1,8-diazafluoren-9-one (DFO) for both fresh and aged prints. Moisture content of the paper substrates on which the prints had been deposited was measured and a correlation found with percentage ambient relative humidity (% RH). Determination of visible color and fluorescence as it corresponded to percentage moisture content allowed for defining critical threshold levels necessary for achieving optimal results. Correlating these values with % RH then allowed for the development of standard operating procedures for obtaining best possible print development. Through this work, it was determined that a 7.4% v/v formulation of Ind-Zn having petroleum ether as a carrier solvent yielded the most optimal results when processing methods optimized for % RH in the laboratory were utilized. Both initial color development and fluorescence were superior to that of DFO; prints developed with Ind-Zn were a minimum of 6.5 units dE* darker and more red than with DFO for all substrates tested. Processing with Ind-Zn on the majority of the substrates examined yielded fluorescence intensity values approximately four times greater than with DFO.
Idazoxan, an alpha 2 antagonist, augments fluphenazine in schizophrenic patients: a pilot study. (1993)

Idazoxan, a selective alpha 2-adrenergic antagonist, was added to stable doses of fluphenazine treatment in six patients with schizophrenia who participated in a double-blind, placebo-controlled pharmacologic study. Compared with fluphenazine alone, combining idazoxan (mean dose, 120 mg/day) with fluphenazine (mean dose, 28 mg/day) resulted in a significant decrease in Brief Psychiatric Rating Scale total symptoms (p < 0.05). Symptom ratings returned to baseline upon idazoxan discontinuation. No significant effects of idazoxan were observed on fluphenazine levels in plasma or on extrapyramidal symptoms. These pilot data are compatible with the notion that increased noradrenergic neurotransmission may enhance the therapeutic effects of typical neuroleptics in schizophrenia.
