Theoretical modeling of the relationship between Young's modulus and formulation variables for segmented polyurethanes (2007)

Abstract We describe a new modeling approach to prediction of Young's modulus of segmented polyurethanes. This approach combines micromechanical models with thermodynamic considerations based on the theory of block copolymers. The resulting model predicts both the equilibrium morphology and the “ideal” Young's modulus of a segmented polyurethane polymer as a function of its formulation (hard segment chemical structure, hard segment weight fraction, soft segment equivalent weight) and temperature. © 2007 Wiley Periodicals, Inc.

E-BUSINESS IS GOOD BUSINESS (2000)

Railroads have always been ahead of most industries in their use of computers. Presently, railroads are finding that the Web can speed up and improve customer and vendor contacts. Some of the e-commerce systems in use and being developed for the railroad industry are discussed.
A public key signature for authentication in telephone (2003)

This paper presents an authentication method for telephone signals using a public key signature. An analog telephone signal needs a special signature which is robust to noise and other disturbances in the telephone line. The signature is generated from some part of the telephone signal using a robust Hash function. The Hash function works by projecting some parts of the telephone signal to N patterns of pseudo noise to produce Hash bits. The output of the Hash function is encrypted using RSA as the signature and then inserted into some other part of the telephone signal as a watermark using spread spectrum modulation without disturbing the conversation. This paper also discusses the possibility of producing false telephone conversation and the robustness of the signature.
Positive Control of Yeast Meiotic Genes by the Negative Regulator UME6 (1995)

The yeast meiotic activator IME1 stimulates transcription of many early meiotic genes. These genes share a 5' sequence called URS1. URS1 sites function as repression sites in cells that lack IME1; we show here that URS1 sites are weak activation sequences in cells that express IME1. Repression through URS1 sites is known to depend upon the URS1-binding protein UME6. We have identified a UME6 allele (previously called rim16-12) that causes a defect in IME1-dependent activation of meiotic genes but not in repression through URS1 sites. In contrast, a ume6 null mutation causes defects in both IME1-dependent activation and in repression through URS1 sites. A LexA-UME6 fusion protein is an IME1-dependent transcriptional activator, whereas a LexA-UME6 fusion carrying the rim16-12 substitution cannot activate transcription. These findings argue that IME1 activates meiotic genes by converting UME6 from a negative regulator to a positive regulator; the rim16-12 mutant protein is defective in conversion to a positive regulator.
Synthesis and Light-Emitting Properties of Bipolar Oligofluorenes Containing Triarylamine and 1,2,4-Triazole Moieties (2006)

A facile approach for synthesis of bipolar oligofluorenes, TAZ-OF(n)-NPh, n = 2 or 3 end-capped with hole-transporting diphenylamino and electron-transporting triazole moieties by Suzuki cross-coupling as the key reaction has been developed. This novel bipolar oligofluorenes exhibited blue-emission, high thermal and morphological stabilities. The single-layer OLED based on TAZ-OF(2)-NPh exhibited superior device performance with a maximum luminance of 1128 cd m(-2) and luminance efficiency of up to 0.83 cd A(-1).
Ozone inactivation of Cryptosporidium parvum in demand-free phosphate buffer determined by in vitro excystation and animal infectivity (1993)

Inactivation of Cryptosporidium parvum oocysts by ozone was performed in ozone demand-free 0.05 M phosphate buffer (pH 6.9) in bench-scale batch reactors at 7 and 22 degrees C. Ozone was added to each trial from a concentrated stock solution for contact times ranging from 5 to 15 min. The viability of the control and treated oocysts was determined by using in vitro excystation and infection in neonatal CD-1 mice. It was found that excystation consistently underestimated inactivation when compared with animal infectivity (P < or = 0.05). As inactivations increased, the difference between excystation and infectivity also increased. The inactivation kinetics of C. parvum by ozone deviated from the simple first-order Chick-Watson model and was better described by a nonlinear Hom model. The use of the Hom model for predicting inactivation resulted in a family of unique concentration and time values for each inactivation level rather than the simple CT product of the Chick-Watson model.
A simple and fast microfluidic approach of same-single-cell analysis (SASCA) for the study of multidrug resistance modulation in cancer cells (2011)

Due to the cellular heterogeneity in multidrug resistance (MDR) cell populations, positive drug effects on the modulation of MDR can be obscured in conventional methods, especially when only a small number of cells are available. To address cellular variations among different MDR cells, we report a new microfluidic approach to study drug effect on MDR modulation, by investigating drug accumulation of daunorubicin in MDR leukemia cells. We have demonstrated that the new approach of same-single-cell analysis by accumulation (denoted as SASCA-A) is not only superior to different-single-cell analysis, but also has key advantages over our previous approach of same-single-cell analysis. First, SASCA-A is much simpler as it does not require multiple cycles of drug uptake and drug efflux. Second, it is faster, only taking about one fourth of the time used in the previous approach. Third, it provides a more 'identical' and reliable control because it compares the time points just before MDR modulator tests. To help understand the dynamics of drug accumulation in MDR cells, we also developed a mathematical model to describe the kinetics of drug accumulation conducted in individual cells. The SASCA-A method will benefit drug resistance research in minor cell subpopulations (e.g., cancer "stem" cells) because this method requires only a small number of cells in identifying the MDR reversal effect.
Electronic Band Structure of Titania Semiconductor Nanosheets Revealed by Electrochemical and Photoelectrochemical Studies (2004)

Electrochemical and photoelectrochemical studies were conducted on self-assembled multilayer films of titania nanosheets on a conductive ITO substrate. Cyclic voltammogram (CV) curves indicated that the titania nanosheet electrode underwent insertion/extraction of Li(+) ions into/from the nanosheet galleries, associated with reduction/oxidation of Ti(4+)/Ti(3+). These processes accompanied reversible changes in UV-vis absorption of the titania nanosheet electrodes. Applying a negative bias of -1.3 V (vs Ag/Ag(+)) and lower brought about absorption reduction where the wavelength is shorter than 323 nm, and vice versa, indicating a flat-band potential of (approximately) -1.3 V and a band gap energy of 3.84 eV. Photocurrents were generated from the titania nanosheet electrodes under a positive bias. The onset potential for photocurrent generation from the titania nanosheet electrodes was around -1.27 V, and the band gap energy estimated from the photocurrent action spectra was 3.82 eV, in excellent agreement with the values obtained from the spectroelectrochemical data. The lack of difference in the band gap energies for titania nanosheet electrodes with different numbers of layers suggests that a nanosheet is electronically isolated in multilayer assemblies without affecting the electronic state of neighboring nanosheets. Similar measurements on the anatase-type TiO(2) electrode revealed that the lower edge of the conduction band for the titania nanosheet is approximately 0.1 V higher than that for anatase, while the upper edge of the valence band is 0.5 V lower.
Bioassay detects soluble MAdCAM‐1 in body fluids (2004)

Mucosal addressin cell adhesion molecule (MAdCAM-1) is a key player in mediating the infiltration of leucocytes into chronically inflamed tissues. Five anti-MAdCAM-1 monoclonal antibodies (mAb), designated 17F5, 201F7, 314G8, 377D10 and 355G8, were generated by fusion of P3 x 63Ag8.653 myeloma cells with spleen cells from BALB/c mice immunized with recombinant human MAdCAM-1-Fc. The latter four mAb recognize the ligand-binding first Ig domain, and block T -cell adhesion to MAdCAM-1. The non-blocking mAb 17F5 recognizes the mucin domain. Extensive analysis of a large panel of paraffin-embedded human tissues revealed that the 314G8 mAb detected MAdCAM-1 on venules in the spleen and small intestine. MAdCAM-1 was strongly expressed in the synovium of osteoarthritis patients, predominantly on the endothelial lining of blood vessels, but also within the vessel lumen. An ELISA, based on mAb 377D10 and 355G8, was developed to determine whether soluble MAdCAM-1 was present in body fluids, and to measure the levels present. The assay detected soluble MAdCAM-1 in the serum and urine of healthy donors, at levels similar to those of soluble forms of the related CAM, ICAM-1 and VCAM-1. The anti-MAdCAM-1 antibodies and assay developed here may be useful therapeutically in the treatment of inflammation in humans. Similarly, they may be useful diagnostically to monitor the presence and levels of MAdCAM-1.
Predictors of Success for First Stage Neuromodulation: Motor Versus Sensory Response (2006)

A positive quadripolar test stimulation (greater than 50% improvement in symptoms) with InterStim sacral neuromodulation is more likely when intraoperative lead placement results in positive motor response vs only sensory response.
Repair of wastewater microorganisms after ultraviolet disinfection under seminatural conditions (1997)

Repair of wastewater microorganisms after ultraviolet (UV) disinfection was studied by incubating secondary effluent previously irradiated to UV doses of 40 to 60 mW·s/cm 2 in diffusion chambers for 2 to 24 hours. For somatic coliphage repair estimations, the effluent was incubated in flasks for 2 hours. There was only slight repair of fecal streptococci, and it did not depend on the UV irradiation dose. Repair of the thermotolerant coliforms was a function of the UV dose. Repair corresponded to a maximum increase of 1 log unit after irradiation to 40 mW·s/cm 2 , and to smaller increases after 50 or 60 mW·s/cm 2 . No relationship was observed between repair and suspended solids content of the effluent in the range of 4 to 12 mg/L. For the Salmonella , no repair was observed after a 60‐mW·s/cm 2 irradiation and a 24‐hour incubation. No repair was observed for the viruses in nine in‐flask incubations, with coliforms showing increases between 1 and 2 log units in the same flasks. Compared with the coliforms, this absence of repair of microorganisms that cause the greatest health risk in bathing and shellfish‐breeding zones brings interesting perspectives in the debate of post‐UV‐irradiation repair.
Electromagnetic ossicular augmentation device. (1995)

Conventional hearing aids have a number of limitations inherent to amplifying sound in the narrow confines of the external auditory canal. Disadvantages include acoustic feedback, poor fidelity, and the stigmata of aging. Since 1986, Michigan Ear Institute and Smith and Nephew Richards Company have been investigating the feasibility of a new device that converts sound to an electromagnetic field. The efficacy and safety of electromagnetic-induced hearing was sufficient enough to have the Federal Food and Drug Administration approve a pilot study of ten patients with a sensorineural hearing loss in whom a target magnet is implanted beneath the tympanic membrane. A status report of this study and a review of our preceeding investigations are presented in this article.

Random access channel (RACH) parameters optimization in WCDMA systems (2005)

The random access procedure, defined by the 3rd Generation Partnership Project (3GPP), is based on a slotted Aloha approach with fast acquisition indication, that is carried out in uplink by the random access channel (RACH) and acquisition indicator channel (AICH) in the downlink. In this paper, the RACH performance in a single omni cell under shadowing and fast-fading conditions is analyzed. An optimization procedure is performed to obtain, according to random access delay and random access success ratio, optimal values for RACH radio parameters such as the power offset between consecutive preambles (/spl Delta//sub pp/) and the preamble target signal to interference ratio (SIR/sub t/). Furthermore, curves of preamble signal to interference ratio (SIR), measured at base station point, are presented.
Catalytic O−O Activation Chemistry Mediated by Iron Hangman Porphyrins with a Wide Range of Proton-Donating Abilities (2003)

[reaction: see text] A library of hanging porphyrin xanthene (HPX) compounds containing pendant groups with various proton-donating abilities (pK(a) ranging from approximately 2 to 25) has been synthesized. Their corresponding chloroiron(III) complexes promote the catalase-like disproportionation of hydrogen peroxide. The overall activity and turnover numbers (TONs) are maximal for iron HPX complexes bearing acidic hydrogen-bond pendants. These results establish that careful control of intramolecular proton inventory can dramatically influence the catalytic activation of O-O bonds.

PLUNC: A novel family of candidate host defence proteins expressed in the upper airways and nasopharynx (2002)

The upper respiratory tract, including the nasal and oral cavities, is the major route of entry of pathogens into the body, and early recognition of bacterial products in this region is critical for host defence. A well-established family of four proteins involved in this process are bactericidal/permeability-increasing protein (BPI) and lipopolysaccharide-binding protein (LBP), which are central to the host defence against bacteria, and cholesteryl ester transfer protein (CETP) and phospholipid transfer protein (PLTP), which have also been implicated in this response. In this paper, we demonstrate the existence of a related family of seven human proteins, which we designate PLUNC proteins. The PLUNC proteins are encoded by adjacent genes found within a 300 kb region of chromosome 20, suggesting that they may be under transcriptional control of shared genomic elements, and expression data shows that these proteins are found in overlapping regions of the pulmonary, nasopharyngeal and oral epithelium, sites where the previously described BPI family members are not expressed. Whereas the BPI family are predicted to share very closely similar three-dimensional structures, the PLUNC family is predicted to have much greater variability in the N-terminal domain, corresponding to the active domain of BPI, thus creating the notion of a BPI/PLUNC structural superfamily. We suggest that members of the PLUNC family may function in the innate immune response in regions of the mouth, nose and lungs, which are sites of significant bacterial exposure.
NEW YORK DERMATOLOGICAL SOCIETY (1925)

<h3>Urticaria Pigmentosa. Presented by Dr. Howard Fox.</h3> G. B., a boy, aged 3½ years, born of American parents, had suffered for three years from the eruption. It was present on the trunks and extremities, and consisted of relatively few light brownish macules averaging one-quarter inch (0.6 cm.) in diameter. According to the mother's statement, there had never been any change in the eruption since its onset, none of the lesions having disappeared so far as she was aware. There were no subjective symptoms. On friction, the lesions became somewhat reddened but not appreciably elevated. The patient had recently suffered from both scarlatina and varicella. He was a well nourished, apparently normal child. Histologic examination by Dr. J. Frank Fraser showed the presence of mast cells. <h3>DISCUSSION</h3> Dr. Highman: Referring to the question of the mast cells, unless one has a good quality of polychrome methylene blue these cells do not

Non-Isolated Enormous-Voltage-Boosting DC-DC Converter for High Step-up Application (2018)

This work introduces a `non-isolated enormous-voltage-boosting DC-DC converter'. The proposed converter combines a three winding coupled inductor and voltage extension circuit. This converter provides large step-up voltage conversion ratio with reasonable duty cycle, great utilization of leakage energy, elimination of high voltage spikes on the switch. Due to such superiority, allowing utilization of low resistance RDS(on) MOSFET switch. The operating principle and steady state analysis of continuous conduction mode (CCM) are discussed in detail. The MATLAB simulation results for 20V/400V, 250W non-isolated enormous-voltage boosting DC-DC converter are provided to verify the virtue of the proposed converter.
Ultrashort echo time (UTE) MRI for the assessment of caries lesions (2013)

The presented data provide evidence that UTE MR imaging can be applied for the identification of caries lesions. Although the current data suggest an even higher sensitivity of UTE MRI, some limitations must be expected from dental fillings.
Plasma Treatment of Polymers (2003)

Abstract Plasma treatment of polymers encompasses a variety of plasma technologies and polymeric materials for a wide range of applications and dates back to at least the 1960s. In this article we provide a brief review of the United States patent literature on plasma surface modification technologies and a brief review of the scientific literature on investigations of the effects of plasma treatment, the nature of the plasma environment, and the mechanisms that drive the plasma–surface interaction. We then discuss low‐radio‐frequency capacitively coupled nitrogen plasmas and their characteristics, suggesting that they provide significant plasma densities and populations of reactive species for effective plasma treatments on a variety of materials, particularly when placing the sample surface in the cathode sheath region. We further discuss surface chemical characterization of treated polymers, including some results on polyesters treated in capacitively coupled nitrogen plasmas driven at 40 kHz. Finally, we connect plasma characterization with surface chemical analysis by applying a surface sites model to nitrogen uptake of poly(ethylene terephthalate) (PET) and poly(ethylene naphthalate) (PEN) treated in a 40 kHz nitrogen plasma. This example serves to suggest an interesting practical approach to comparisons of plasma treatments. In addition, it suggests an approach to defining the investigations required to conclusively identify the underlying treatment mechanisms.
