Benchmark database of accurate (MP2 and CCSD(T) complete basis set limit) interaction energies of small model complexes, DNA base pairs, and amino acid pairs (2006)

MP2 and CCSD(T) complete basis set (CBS) limit interaction energies and geometries for more than 100 DNA base pairs, amino acid pairs and model complexes are for the first time presented together. Extrapolation to the CBS limit is done by using two-point extrapolation methods and different basis sets (aug-cc-pVDZ - aug-cc-pVTZ, aug-cc-pVTZ - aug-cc-pVQZ, cc-pVTZ - cc-pVQZ) are utilized. The CCSD(T) correction term, determined as a difference between CCSD(T) and MP2 interaction energies, is evaluated with smaller basis sets (6-31G** and cc-pVDZ). Two sets of complex geometries were used, optimized or experimental ones. The JSCH-2005 benchmark set, which is now available to the chemical community, can be used for testing lower-level computational methods. For the first screening the smaller training set (S22) containing 22 model complexes can be recommended. In this case larger basis sets were used for extrapolation to the CBS limit and also CCSD(T) and counterpoise-corrected MP2 optimized geometries were sometimes adopted.

The groups of the nano-hydroxyapatite, the hydroxyapatite-nanocrystals and the tricalcium-phosphate exhibited significant delta E values between baseline and after hydrodynamic shear force application (P<0.05). In conclusion, the materials used in the study are very promising alternatives to oxidizing bleaching agents.
Liquid metal source of gold ions (1981)

A fully engineered liquid metal field emission source of gold ions has been developed, operating with low heater power (&lt;30 W) and without forced cooling. The design and performance of the source are described in detail. The present design can also be used to produce sources of a variety of elements, other than gold, including tin, bismuth, and lead. It provides a versatile and reliable research tool which is fully compatible with ultrahigh vacuum installations. Potential fields of application include materials development and surface analysis.
Synthesis, Characterization and Biomedical Properties of UV-Cured Polyurethane Acrylates Containing a Phosphorylcholine Structure (2012)

In order to develop a simple, economical and rapid approach to incorporate 2-methacryloyloxyethyl phosphorylcholine (MPC) with other monomers without any solvent, we prepared a series of ultraviolet cured poly(urethane acrylate) (PUA) membranes containing different MPC content. Their chemical structure and surface properties were investigated by FT-IR, XPS, water swelling ratio and water contact angle measurement, while the biocompatibilities were evaluated through fibrinogen adsorptions, platelet adhesion and plasma recalcification time determination. The results demonstrate that the phosphorylcholine (PC) groups were successfully introduced into the PUA system by the UV-curing approach and the all PC-containing membranes showed better biocompatibility than those without PC moiety. The UV-curing method is potentially to be applied in the coating of medical devices which require biocompatibility and manufacturing efficiency.
Repeated Downsizing Contact: The Effects of Similar and Dissimilar Layoff Experiences on Work and Well-Being Outcomes. (2004)

In this longitudinal study, the authors compared 1,244 white- and blue-collar workers who reported 0, 1, or 2 contacts with layoffs; all were employees of a large manufacturing company that had engaged in several mass waves of downsizing. Consistent with a stress-vulnerability model, workers with a greater number of exposures to both direct and indirect downsizing reported significantly lower levels of job security and higher levels of role ambiguity, intent to quit, depression, and health problems. Findings did not support the idea that workers became more resilient as they encountered more layoff events. The authors found only partial evidence that the similarity or dissimilarity of the type of repeated downsizing exposure played a role in how workers reported changes in these outcome variables.
Disruption of CFTR-Dependent Lipid Rafts Reduces Bacterial Levels and Corneal Disease in a Murine Model of<i>Pseudomonas aeruginosa</i>Keratitis (2008)

P. aeruginosa enters human corneal epithelial cells via lipid rafts containing CFTR, and disruption of raft-mediated uptake of this organism by CD protects against disease and reduces bacterial levels in the mouse model of keratitis.
Ordered Porous Carbon with Tailored Pore Size for Electrochemical Hydrogen Storage Application (2006)

Ordered porous carbon with tailored pore size represents an innovative concept in electrochemical hydrogen storage. This work deals with physical characteristics and electrochemical hydrogen storage behavior of the ordered porous carbons with well-tailored pore size, synthesized by a replica technique using hexagonal mesoporous silica as templates. By using a mixture of two surfactants (HTAB and C16EO8) at different ratios, it is possible to control the wall thickness of silica and, consequently, the pore diameter of carbons within a narrow range of 2.1-2.8 nm. In addition, highly developed ultramicroporosity (pore size smaller than 0.7 nm), which plays a predominant role in hydrogen storage, can be produced in the ordered porous carbons. A discharge capacity of up to 527 mAh/g (corresponding to 1.95 wt % hydrogen storage) has been achieved in 6 M KOH for the ordered porous carbon. Furthermore, the ordered porous carbons also possess excellent capacity retainability after charge-discharge cycles and rate capability.
Schistosomiasis (1977)

Schistosomiasis, one of the more important worm infestations of mankind, is widely distributed over three continents, affecting more than 200 million people, and is often associated with considerable morbidity. Unlike almost all other parasitic infestations, schistosomiasis is increasing in prevalence as man attempts to use water and land resources more efficiently. The development of many countries in Africa and South America depends on the construction of new dams and the initiation of irrigation projects, which provide ideal breeding places for the snail host of the parasite. Schistosomiasis is therefore a challenge not only for physicians and scientists but also for . . .
La concepción aristotélica de la vida contemplativa en algunos "magistri artium" del siglo XIII (2011)

Resumen Algunas tesis del syllabus redactado por Tempier en 1277 condenaban la idea, de inspiracion aristotelica, de que el filosofo vivia en el mejor estado posible al hombre. En este trabajo nos proponemos: 1) establecer en que medida dicha idea fue sostenida por los magistri artium, 2) dar cuenta de la complejidad del debate historiografico establecido en torno a esta idea y 3) mostrar que tal concepcion no debe reducirse a una mera reelaboracion del ideal aristotelico, pues constituye la expresion del espiritu particular de los maestros de artes del siglo XIII.

Chemotherapy for nonmetastatic osteogenic sarcoma: the Memorial Sloan-Kettering experience. (1992)

Intensive chemotherapy can achieve DFS for a high proportion of patients with OS. Although it is a powerful predictor of DFS, histologic response to preoperative chemotherapy cannot be assessed at diagnosis. We have not shown an ability to salvage patients with an unfavorable response. We need to increase the proportion of patients with a favorable response, identify the patients who will have an unfavorable response, and develop novel treatments to salvage poor responders.
Identifying the Scan and Attack Infrastructures Behind Amplification DDoS Attacks (2016)

Amplification DDoS attacks have gained popularity and become a serious threat to Internet participants. However, little is known about where these attacks originate, and revealing the attack sources is a non-trivial problem due to the spoofed nature of the traffic.
<i>N-</i>Tosyloxycarbamates as a Source of Metal Nitrenes:  Rhodium-Catalyzed C−H Insertion and Aziridination Reactions (2005)

The rhodium-catalyzed decomposition of N-tosyloxycarbamates to generate metal nitrenes which undergo intramolecular C-H insertion or aziridination reaction is described. Aliphatic N-tosyloxycarbamates produce oxazolidinones with high yields and stereospecificity through insertion in benzylic, tertiary, and secondary C-H bonds. Intramolecular aziridination occurs with allylic N-tosyloxycarbamates to produce aziridines as single diastereomers. The reaction proceeds at room temperature using a rhodium catalyst and an excess of potassium carbonate and does not require the use of strong oxidant, such as hypervalent iodine reagents. A rhodium nitrene species is presumably involved, as both reactions are stereospecific.
A practical approach to "channel borrowing" for microcells in GSM systems (2002)

This paper describes a novel method to determine the least interfered channel for microcells in GSM radio networks. The determination of this optimum channel is based on analysis of signal level measurements from the serving and neighbouring cells. These measurements are provided as part of the standard GSM functionality by mobile stations of ordinary subscribers while being in a call. The method has been applied to different cell types in various networks and proved to be very useful in achieving high capacity networks and good call quality.
Medulloblastoma: The Treatment Results and Literature Review (1995)

Twenty-four children (M:F=13:11) whose ages ranged from 10 months to 13 years (median age 6 years) with histologically confirmed medulloblastomas were treated at Mackay Memorial Hospital from January 1982 to December 1991. All 24 patients were to undergo extensive resection and then to receive a primary course of adjuvant craniospinal axis irradiation with a local posterior fossa boost. The anatomical extent of the disease was classified according to the Chang staging system. Headache, vomiting and an unsteady gait were the major presentations in this series. The overall 5-year survival rate was 58% respectively. In addition, the overall 5-year survival rate was statistically higher in females than in males (73% vs 46%, P=0.03), in early-stage tumors (T1 & T2) than in late-stage tumors (T3 & T4) (71% vs 40%, P=0.066), and in patients who received a dose of 50 Gy or more to the posterior fossa than in those who received a lower dose (73% vs 33%, P=0.05). The extent of surgery had no impact on the survival rate (P=0.13). Patients older than 5-years of age had a higher 5-year survival rate but it was not statistically significant (71% vs 40%, P=0.066). The overall relapse rate was 50% in our series with only 3 eases survived in the follow-up. From the literature review and the results of this series, we can conclude that by more than 50 Gy posterior fossa irradiation, the overall survival rate has much improved, so the late sequellae have become an important subject. However, there is still poor outcome in advanced disease and recurrent disease. The optimal selection criteria are urgently required to reduce long-term complications and to increase survival in poor outcome groups.
Advanced thermal management for temperature homogenization in high-power lithium-ion battery systems based on prismatic cells (2015)

In order to extend the lifetime of lithium-ion batteries, an advanced thermal management concept is investigated. In battery modules, different cell temperatures lead to higher efforts in cell balancing and reduce the system's lifetime. Especially when battery systems with phase change material operate outside the phase transition range high temperature gradients can occur that result in different ageing speeds of the cells. The effect of temperature dependent ageing of the battery cells is further investigated. A battery module concept is developed with focus on temperature homogenization by optimization of the module design and material characteristics. The module design combines several approaches including optimized interface pads, thermal storage materials and anisotropic multilayer graphite sheets. Numerical simulations with material and geometrical models are used for the evaluation of the concept with reference models. In addition, a battery cell model is set up, which describes the reversible and irreversible heat generation rate. Using model-order-reduction, the simulations are accelerated by reduction of the calculation time. In order to optimize the material parameters, the simulations are analyzed with design exploration techniques. As a result, the overall temperature differences in the module are minimized and the temperature distribution is homogenized with new developed interface pads. In combination with high thermally conductive synthetic graphite sheets the pads also compensate the insulating behavior of thermal storage material, which is used for temperature peak reduction and to smooth temperature changes.
Reduction of Common Mode EMI in a Full-Bridge Converter through Automatic Tuning of Gating Signals (2006)

Theoretically, a full-bridge converter under bipolar PWM should produce very little common mode noise because the two phase-legs can compensate for each other, but this feature is often disrupted by different transmission delays of the gating signals. In this paper, a method to address this problem through automatic tuning of the pulse edges of gating signals is proposed. Specifically, the CM noise current is sensed by a DSP and the noise energy is calculated, then a search algorithm is employed to tuning the pulse edges of the gating signals in order to minimize the CM noise. Experimental results show that up to 10 dB reduction of the CM current can be obtained from 500 kHz to 5 MHz. Implementation of the this method requires little hardware expense, and the software can be synthesized into the main control DSP of the converter

Functional Role of Asparaginyl Endopeptidase Ubiquitination by TRAF6 in Tumor Invasion and Metastasis (2014)

Our study elucidates a novel mechanism of AEP regulation and an alternative oncogenic pathway for TRAF6 in breast cancer, which suggests that AEP and TRAF6 protein levels may have prognostic implications in breast cancer patients. Thus, AEP may serve as a biomarker as well as new therapeutic target.
Traffic Flow Control Using Probe Vehicle Data (2010)

UTMS (Universal Traffic Management Society) of Japan is researching the technologies and specifications for traffic flow control using probe data for CO2 emissions reduction. First, the authors defined the services which realized in advanced traffic flow control and examined the technological requirements of each service in 2008. In 2009, they conducted some simulation experiments to verify the requirements of probe data and key technologies for the realization of the services. The authors report on the outline of the services and the results of the simulation experiments in this paper.
Micron‐resolution ranging of cornea anterior chamber by optical reflectometry (1991)

Noncontact, high resolution measurements of anterior eye structures using optical coherence domain reflectometry are described. Distances between intraocular structures are measured by directing a beam of short coherence length light onto the eye and performing an interferometric measurement on the optical group delay of reflected signals. Measurements of corneal thickness, corneal excision depth, and anterior chamber depth are demonstrated in vitro, and the location of tissue boundaries is resolved to within +/- 2 microns. The full-width-half-maximum longitudinal resolution is 10 microns. Sensitivities to reflected signals as small as 10(-10) of the incident power are achieved by heterodyne detection.
Interaction of Non-Specific Inhibitor and Rabies Virus Haemagglutinin (1977)

In order to elucidate the properties of an inhibitor of rabies virus haemagglutinin in normal animal sera, experiments were made with the HEP Flury strain and calf serum which contains the inhibitor. The results of physico-chemical treatment, gel-filtration and density analysis suggested lipoprotein involvement. When inhibitor and haemagglutinin were mixed, the separate activities could be recovered from the mixture by centrifuging on a sucrose density gradient. By contrast, neither haemagglutinin nor inhibitor could be recovered by this treamtnet when the inhibitor was added at the start of virus growth. The binding of inhibitor with rabies virus during virus growth seems irreversible and different from the binding of inhibitor with pre-formed rabies haemagglutinin.
Background removal in image indexing and retrieval (2003)

This paper presents our research in image content-based indexing and retrieval, a key technology in digital image libraries. In most of the existing image content-based techniques, image features used for indexing and retrieval are global, features computed over the entire image. The major problem with the global image feature-based retrieval methods is that background features can be easily mistaken as object features. When a user attempts to retrieve images using color features, he/she usually means the color feature of objects of interests contained in the image. The approach we describe in this paper utilizes color clusters for image background analysis. Once the background regions are identified, they are removed from the image indexing procedure, and therefore no longer interfere with the meaningful image content during the retrieval process.
FISH on metaphase and interphase chromosomes demonstrates the physical order of the genes for GPI, CRC, and LIPE in pigs (1995)

The porcine genes for glucose phosphate isomerase (GPI), calcium release channel (CRC), and hormone-sensitive lipase (LIPE) map to the long arm of chromosome 6. Earlier studies, using fluorescence in situ hybridization (FISH), mapped the three loci to the same band, viz., 6q12. To ascertain the relative order of the three genes, we first conducted three double-color FISH experiments, cohybridizing two of the probes at a time. These experiments demonstrated that the gene order was cen-GPI-CRC-LIPE. This order was confirmed by cohybridizing the three probes to both metaphase and interphase chromosomes.
A Notch Filter Instrument for Measuring ELF (Extremely Low Frequency) MSK (Minimum Shift Keying) Signals. (1988)

Abstract : This report presents a notch filter technique for measuring extremely low frequency (ELF) signals in the presence of other higher-level, low frequency voltages, specifically 60 Hz and harmonics, on public utility systems. The report also describes the design, development, and operation of a special-purpose notch filter instrument that allows the practical realization of this measurement technique.

On combining target-location ellipses (1989)

On the assumption of Gaussian statistics, expressions are obtained for the center, semiaxes, and the inclination of the major axis of a single location ellipse that combines the information in several location ellipses and/or bearings obtained from independent fixes on the same target. When all of the given ellipses have finite major axes and they are all shifted so as to have the same center, the resultant ellipse will not touch any of them.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Ion-Induced Nucleation<i>in Solution</i>:  Promotion of Solute Nucleation in Charged Levitated Droplets (2007)

We have investigated the nucleation and growth of sodium chloride in both single quiescent charged droplets and charged droplet populations that were levitated in an electrodynamic levitation trap (EDLT). In both cases, the magnitude of a droplet's net excess charge (ions(DNEC)) influenced NaCl nucleation and growth, albeit in different capacities. We have termed the phenomenon ion-induced nucleation in solution. For single quiescent levitated droplets, an increase in ions(DNEC) resulted in a significant promotion of NaCl nucleation, as determined by the number of crystals observed. For levitated droplet populations, a change in NaCl crystal habit, from regular cubic shapes to dome-shaped dendrites, was observed once a surface charge density threshold of -9 x 10(-4) e.nm(-2) was surpassed. Although promotion of NaCl nucleation was observed for droplet population experiments, this can be attributed in part to the increased rate of solvent evaporation observed for levitated droplet populations having a high net charge. Promotion of nucleation was also observed for two organic acids, 2,4,6-trihydroxyacetophenone monohydrate (THAP) and alpha-cyano-4-hydroxycinnamic acid (CHCA). These results are of direct relevance to processes that occur in both soft-ionization techniques for mass spectrometry and to a variety of industrial processes. To this end, we have demonstrated the use of ion-induced nucleation in solution to form ammonium nitrate particles from levitated droplets to be used in in vitro toxicology studies of ambient particle types.
