LENS: Leveraging social networking and trust to prevent spam transmission (2011)

In this paper we introduce LENS, a novel spam protection system based on the recipient's social network, which allows correspondence within the social circle to directly pass to the mailbox and further mitigates spam beyond social circles. The key idea in LENS is to select legitimate and authentic users, called Gatekeepers (GKs), from outside the recipients social circle and within pre-defined social distances. Unless a GK vouches for the emails of potential senders from outside the social circle of a particular recipient, those e-mails are prevented from transmission. In this way LENS drastically reduces the consumption of Internet bandwidth by spam. Using extensive evaluations, we show that LENS provides each recipient reliable email delivery from a large fraction of the social network. We also evaluate the computational complexity of email processing with LENS deployed on two Mail Servers (MSs) and compared it with the most popular content-based filter i.e SpamAssassin. LENS proved to be fast in processing emails (around 2-3 orders of magnitude better than SpamAssassin) and scales efficiently with increasing community size and GKs.
Adaptively Preconditioned GMRES Algorithms (1998)

The restarted GMRES algorithm proposed by Saad and Schultz [SIAM J. Sci. Statist. Comput., 7 (1986), pp. 856--869] is one of the most popular iterative methods for the solution of large linear systems of equations Ax=b with a nonsymmetric and sparse matrix. This algorithm is particularly attractive when a good preconditioner is available. The present paper describes two new methods for determining preconditioners from spectral information gathered by the Arnoldi process during iterations by the restarted GMRES algorithm. These methods seek to determine an invariant subspace of the matrix A associated with eigenvalues close to the origin and to move these eigenvalues so that a higher rate of convergence of the iterative methods is achieved.
Effect of entanglement on brittle‐ductile transition in polyethylene (2001)

Abstract The brittle ductile transition temperature (BDTT) of polyethylene with different degrees of entanglement density produced by crosslinking was evaluated using the Charpy impact test. BDTT was defined as the temperature at which the Charpy impact value Et changed abruptly from low to higher values. The increase in entanglement density brought about only a slight fall in BDTT, although that led to an increase in Et at ambient temperature corresponding to the occurrence of a dimple type fracture. A transition model between brittle fracture, patchwork type fracture (craze‐like) and yielding deformation, depending on the degree of crosslinking, was proposed to explain those experimental results.
Self‐Organized Gradient Hole Injection to Improve the Performance of Polymer Electroluminescent Devices (2007)

Abstract A new approach to forming a gradient hole‐injection layer in polymer light‐emitting diodes (PLEDs) is demonstrated. Single spin‐coating of hole‐injecting conducting polymer compositions with a perfluorinated ionomer results in a work function gradient through the layer formed by self‐organization, which leads to remarkably efficient single‐layer PLEDs (ca. 21 cd A –1 ). The device lifetime is significantly improved (ca. 50 times) compared with the conventional hole‐injection layer, poly(3,4‐ethylenedioxythiophene)/poly(styrene sulfonate). These results are a good example for demonstrating that the shorter lifetime of PLEDs compared with small‐molecule‐based organic LEDs (SM‐OLEDs) is not mainly due to the inherent degradation of the polymeric emitter itself. Hence, the results open the way to further improvements of PLEDs for real applications to large‐area, high‐resolution, and full‐color flexible displays.
Deep Learning Approach for Short-Term Stock Trends Prediction Based on Two-Stream Gated Recurrent Unit Network (2018)

Financial news has been proven to be a crucial factor which causes fluctuations in stock prices. However, previous studies heavily relied on analyzing shallow features and ignored the structural relation among words in a sentence. Several sentiment analysis studies have tried to point out the relationship between investors' reaction and news events. However, the sentiment dataset was usually constructed from the lingual dataset which is unrelated to the financial sector and led to poor performance. This paper proposes a novel framework to predict the directions of stock prices by using both financial news and sentiment dictionary. The original contributions of this paper include the proposal of a novel two-stream gated recurrent unit network and Stock2Vec-a sentiment word embedding trained on financial news dataset and Harvard IV-4. Two main experiments are conducted: the first experiment predicts S&P 500 index stock price directions using the historical S&P 500 prices and the articles crawled from Reuters and Bloomberg, and the second experiment forecasts the price trends of VN-index using VietStock news and stock prices from cophieu68. Results show that: 1) two-stream GRU outperforms state-of-the-art models; 2) Stock2Vec is more efficient in dealing with financial datasets; and 3) applying the model, a simulation scenario proves that our model is effective for the stock sector.
Multi-fingered telemanipulation - mapping of a human hand to a three finger gripper (2008)

If a teleoperation scenario foresees complex and fine manipulation tasks a multi-fingered telemanipulation system is required. In this paper a multi-fingered telemanipulation system is presented, whereby the human hand controls a three-finger robotic gripper and force feedback is provided by using an exoskeleton. Since the human hand and robotic grippers have different kinematic structures, appropriate mappings for forces and positions are applied. A point-to-point position mapping algorithm as well as a simple force mapping algorithm are presented and evaluated in a real experimental setup.
Constructing 3D-Printable CAD Models of Prostates from MR Images (2013)

This paper describes the development of a procedure to generate patient-specific, three-dimensional (3D) solid models of prostates (and related anatomy) from magnetic resonance (MR) images. The 3D models are rendered in STL file format which can be physically printed or visualized on a holographic display system. An example is presented in which a 3D model is printed following this procedure.
[Effect on the body of rats of rations varying in protein content in acrylomitrile poisoning]. (1979)

The effect of protein of isocaloric rations (10, 18 and 30 per cent of the total calorific value) differing in its proportion on the course of a subacute poisoning provoked by the acrylic acid nitrile (AAN) in a concentration of 9.7 +/- 2.8 mg/m3 was studied. A comparative study of the results obtained showed that a protein-rich ration produced a more pronounced protective effect. Against its background the AAN metabolites were eliminated from the organism more intensively. This effect could have been occasioned by an excessive supply to the organism together with the additional protein of free sulphur and of SH-group necessary for rendering the cyanides harmless. Considering the results obtained and with the view of a more effective prevention of the AAN poisoning it is advisable to recommend providing workers with a protein-rich medico-prophylactic ration containing an assortment of food products rich in sulphur-containing elements.

A new method to measure plasma levels of activated protein C in complex with protein C inhibitor in patients with acute coronary syndromes (2001)

Our newly devised immunofluorometric sandwich assay for measuring plasma concentrations of activated protein C (APC) in complex with protein C inhibitor (PCI) was compared with testing for conventional markers of myocardial damage CKMB (creatine kinase MB), TNI (troponin I) and hypercoagulability (D-dimer, TAT) in 76 patients with suspected myocardial infarction (MI). APC-PCI complex levels in samples drawn on admission did not correlate with CKMB in the simultaneously drawn sample but correlated closely with maximal CKMB, which reflects MI size (r = 0.52). The areas under the receiver operating characteristics (ROC) curves calculated for the APC-PCI complex results obtained upon admission did not differ significantly from the corresponding values for CKMB, TNI or TAT. Our results show that in patients at risk for MI, the APC-PCI concentration is a sensitive and independent marker that can identify a subgroup of MI patients with normal CKMB but an increased APC-PCI level upon admission. It remains to be determined whether these patients would benefit from early intensive anticoagulant treatment.
DRSA-Based Neuro-Fuzzy Inference Systems for the Financial Performance Prediction of Commercial Banks (2014)

[[abstract]]This study proposes an integrated inference system to predict the financial performance of banks. The model comprises of two stages. At the first stage, the dominance-based rough set approach (DRSA) method is applied to reduce the complexity of the attributes involved, and the obtained decision rules are further refined by the neuro-fuzzy inference technique to indicate the fuzzy intervals for each attribute. The proposed model not only shows how to explore the implicit patterns regarding the bank's performance change, but also refines the knowledge by tuning the parameters of membership functions for each attribute. At the second stage, the directional influences among the core attributes are further explored. To examine the proposed model, a group of real commercial banks in Taiwan is analyzed to construct the model, and five sample banks are tested to validate its effectiveness. The result provides understandable insights regarding the performance prediction problem of banks.
The NSR1 gene encodes a protein that specifically binds nuclear localization sequences and has two RNA recognition motifs. (1991)

We previously identified a protein (p67) in the yeast, Saccharomyces cerevisiae, that specifically recognizes nuclear localization sequences. We report here the partial purification of p67, and the isolation, sequencing, and disruption of the gene (NSR1) encoding this protein. p67 was purified using an affinity column conjugated with a peptide containing the histone H2B nuclear localization sequence from yeast. Using antibodies against p67 we have cloned the gene for this protein. The protein encoded by the NSR1 gene recognizes the wild-type H2B nuclear localization sequence, but does not recognize a mutant H2B sequence that is incompetent for nuclear localization in vivo. Interestingly, the NSR1 protein has two RNA recognition motifs, as well as an acidic NH2 terminus containing a series of serine clusters, and a basic COOH terminus containing arg-gly repeats. We have confirmed the nuclear localization of p67 by immunofluorescence and found that a restricted portion of the nucleus is highlighted. We have also shown that NSR1 (p67) is required for normal cell growth.
Miniature heart cell force transducer system implemented in MEMS technology (2001)

A fully submersible force transducer system for use with isolated heart cells has been implemented using microelectromechanical systems (MEMS) technology. By using integrated circuit fabrication techniques to make mechanical as well as electrical components, the entire low-mass transducer is only a few cubic millimeters in size and is of higher fidelity (approximately 100 nN and 13.3 kHz in solution) than previously available. When chemically activated, demembranated single cells attached to the device contract and slightly deform a strain gauge whose signal is converted to an amplified electrical output. When integrated with a video microscope, the system is capable of optical determination of contractile protein striation periodicity and simultaneous measurement of heart cell forces in the 100-nN to 50-microN range. The average measured maximal force was Fmax = 5.77 +/- 2.38 microN. Normalizing for the cell's cross-sectional area, Fmax/area was 14.7 +/- 7.7 mN/mm2. Oscillatory stiffness data at frequencies up to 1 kHz has also been recorded from relaxed and contracted cells. This novel MEMS force transducer system permits higher fidelity measurements from cardiac myocytes than available from standard macro-sized transducers.
Impedance bandwidth of the square planar monopole (2000)

An analysis of a broadband square planar monopole is presented. The frequency corresponding to the lower edge of the impedance bandwidth may be found by using a simple formula, based on an equivalent cylindrical monopole. To obtain the upper edge frequency accurately, a method-of-moments analysis which employs wire gridding is required. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 24: 185–187, 2000.
The Scientific Ethos : A deviant viewpoint (1970)

The study of science and scientists has attracted sociologists, to any significant extent, only in the last quarter of a century. The earliest papers of any importance in the field are probably those of Robert Merton, written in the late 1930's and early 1940's; Merton's ideas have been extremely influential with all subsequent contributors and it is probably no exaggeration to state that the literature of the subject has been overwhelmingly concerned with the development and extension of Merton's original insights. Certainly in America the work of Barber, Storer, Marcson, Hagstrom, Kornhauser and Shils would seem to justify this contention. In Britain, the sociology of science is not studied as much, but the work of Cotgrove, although by no means ‘following’ Merton, freely acknowledges his influence.
Risk of bladder cancer by source and type of tobacco exposure: A case‐control study (1989)

The association between tobacco use and risk of bladder cancer was investigated in a population-based case-control study conducted in Alberta and south-central Ontario, Canada, between 1979 and 1982. In all, 826 histologically-confirmed cancer cases and 792 randomly selected controls, individually matched to cases for age, sex, and area of residence, were recruited into the study. Compared to those who had never smoked cigarettes, males and females who had ever smoked cigarettes had a statistically highly significant 2-fold increase in risk of bladder cancer; for ex-smokers, the risk was intermediate between that for current smokers and never-smokers. There was a dose-dependent increase in risk of bladder cancer with total lifetime cigarette consumption, of similar magnitude for males and females. In males, risk increased with self-reported degree of inhalation in ex-smokers and in current smokers (statistically significant trend), while in females there was no association in current smokers, and a statistically significant inverse association in ex-smokers. Overall, risks of bladder cancer associated with lifetime consumption of plain and filter cigarettes were similar, and there was little evidence to suggest that switching from plain to filter cigarettes was beneficial. Neither passive smoking nor other forms of tobacco consumption (pipes, cigars, chewing tobacco, or snuff) were associated with altered risk of bladder cancer. The population attributable risk for cigarette smoking was about 47% in males and about 33% in females.
Impedance Spectroscopy Study of PEO-Based Nanocomposite Polymer Electrolytes (2000)

The addition of nanometric fillers (e.g., , ) to polymer electrolytes induces consistent improvement in the transport properties. The increase in conductivity and in the cation transference number is attributed to the enhancement of the degree of the amorphous phase in the polymer matrix, as well as to some acid‐base Lewis type, ceramic‐electrolyte interactions. This model is confirmed by results obtained from a detailed impedance spectroscopy study carried out on poly(ethylene oxide) [P(EO)]‐based polymer electrolyte samples with and without ceramic fillers. © 2000 The Electrochemical Society.

Common-mode voltage reduction method modifying the distribution of zero-voltage vector in PWM converter/inverter system (2001)

This paper proposes a new space-vector pulsewidth modulation (PWM) strategy that can restrict the common-mode voltage within one-third of DC-bus voltage in a PWM converter/inverter system with the synchronization of the switching sequence. In this paper, the generation of the common-mode voltage pulse whose magnitude reaches two-thirds of DC-bus voltage is investigated and the elimination method of this voltage pulse is presented. The proposed method can be easily implemented in software and requires no extra hardware without degradation in control performance of PWM converter/inverter-fed AC motor drives.
A Device for the Intraoperative Identification of the Recurrent Laryngeal Nerve in Piglets (1989)

The recurrent laryngeal nerve (RLN) is one of the most frequently injured nerves in head and neck surgery. Routine identification of the RLN during thyroid surgery has reduced the injury rate from 10% to less than 4%. Difficulty in identification of the RLN contributes to this surgical morbidity. Devices previously used for intraoperative identification of the RLN have failed to achieve the simplicity and reliability necessary for clinical use. This animal study uses a simple double-ballooned endotracheal tube and pressure transducer system, which assists intraoperative RLN identification through nerve stimulation and graphic documentation of vocal fold (VF) motion. Iatrogenic injury is demonstrated by a dampened stimulation-pressure tracing. The RLNs of three piglets were injured and examined, and the degree of injury was correlated with perioperative nerve stimulation patterns. The piglet proved to be an adequate model for laryngeal research. An FDA-approved multi-institutional prospective human study using this system of identification of the RLN is in progress.
SYNTHESIS AND EVOLUTION OF NEW ISOXAZOLO-1,4-QUINONES OF BIOLOGIC INTEREST (2006)

In the exploration of synthesis and chemistry of isoxazoles, we found that the reaction of aromatic nitrile oxides with the Quinone derivatives produced isoxazolo-1,4-quinones is of considerable biological interest. The reductive cleavage of the N-0 bond gave arylimidoyl-3hydroxy-1,4-quinones.
Comparison of Endovenous Radiofrequency Versus 810 nm Diode Laser Occlusion of Large Veins in an Animal Model (2002)

Vein perforations, extremely high intravascular temperatures, failure to cause significant collagen shrinkage, and intact endothelium in an animal model justify a closer look at the human clinical application of the 810 nm endovenous laser technique. Extravasated blood impinging on adjacent structures may theoretically lead to increased peri-operative hematoma and tenderness. Further study and clinical investigation is warranted.
ChemInform Abstract: Ferrous Chelates of EDTA, HEDTA, and SHBED. (1988)

Abstract Careful potentiometric equilibrium pH measurements of 1:1 Fe2+‐(I) and Fe2+‐(II) solutions with rigorous exclusion of oxygen show no indication of hydrolysis up to pH 12. Calculations using data of these systems give only the formation constants of the simple chelates (IV) and (V) and constants for the formation of monoprotonated species at low pH.
Abstract 3670: Effects of Telmisartan, Angiotensin II Receptor Blocker, on Endothelial Function and Aortic Stiffness in Morning Hypertensive Patients with the Metabolic Syndrome and Obstructive Sleep Apnea (2008)

Morning hypertension and the metabolic syndrome (MetS) are recognized as a risk factor for cardiovascular disease, and are reported to be associated with obstructive sleep apnea (OSA). Recently it has been reported that telmisartan has an action of PPAR - γ agonist. We assessed the effects of telmisartan on endothelial function and aortic stiffness in morning hypertensive patients with MetS and OSA. Thirty untreated morning hypertensive patients with MetS and mild or moderate OSA (an apnea-hypopnea index [AHI] 5 – 30) were randomized to receive telmisartan (Telmisartan group, 20 - 40 mg/day, n=15) or amlodipine (Amlodipine group, 2.5 - 5 mg/day, n=15). Flow-mediated dilatation (FMD) and nitroglycerin-induced dilatation (NID) of brachial artery were measured by using ultrasound system. Pulse wave velocity (PWV) was measured by using oscilometric technique. We assessed insulin resistance by HOMA-IR, and measured high sensitivity C-reactive peptide (hsCRP) and thiobarbituric acid reactive substance (TBARS) a...
Modern Compiler Implementation in C: Basic Techniques (1997)

From the Publisher:
This textbook describes all phases of a modern compiler. It includes good coverage of current techniques in code generation and register allocation, as well as functional and object-oriented languages, that is missing from most books. In a concise way, the author describes the most accepted and successful techniques, rather than giving an exhaustive catalog of every possible variant. Detailed descriptions of the interfaces between modules of a compiler are illustrated with actual C header files. A unique feature of the book is a well designed compiler implementation project in C, including front-end and high-tech back-end phases, useful for undergraduate and graduate students as well as computer professionals needing a reference on compiler implementation.
New fluorescent pH sensors based on covalently linkable PET rhodamines (2012)

A new class of rhodamines for the application as indicator dyes in fluorescent pH sensors is presented. Their pH-sensitivity derives from photoinduced electron transfer between non-protonated amino groups and the excited chromophore which results in effective fluorescence quenching at increasing pH. The new indicator class carries a pentafluorophenyl group at the 9-position of the xanthene core where other rhodamines bear 2-carboxyphenyl substituents instead. The pentafluorophenyl group is used for covalent coupling to sensor matrices by "click" reaction with mercapto groups. Photophysical properties are similar to "classical" rhodamines carrying 2'-carboxy groups. pH sensors have been prepared with two different matrix materials, silica gel and poly(2-hydroxyethylmethacrylate). Both sensors show high luminescence brightness (absolute fluorescence quantum yield Φ(F)≈0.6) and high pH-sensitivity at pH 5-7 which makes them suitable for monitoring biotechnological samples. To underline practical applicability, a dually lifetime referenced sensor containing Cr(III)-doped Al(2)O(3) as reference material is presented.
