<sup>1</sup>H and<sup>13</sup>C nuclear magnetic resonance studies of the synthesis of linear segmented polyurethane elastomers (1987)

Linear segmented polyurethane elastomers have been prepared by reaction of polyethyleneoxide with 4,4′-diphenylmethanediisocyanate and the product was subsequently cured with diamines. Chemical analysis of the prepolymer formed using stoichiometric ratios of polyol and diisocyanate indicated that the product was deficient in ‘free’ isocyanate. A number of side reactions can lead to a reduction in the amount of isocyanate available for the chain extension reaction. Infrared, 1H- and 13C-n.m.r. spectroscopy were used to follow the initial end-capping and subsequent chain extension reactions. In order that an unambiguous assignment of the weak peaks observed in the prepolymer and final elastomer spectra could be made, a number of model compounds associated with the side reactions were synthesized and their spectra characterized. It was concluded that the loss of ‘free’ isocyanate in the formation of the prepolymer can be predominantly attributed to the effects of traces of water in the initial reaction mixture.

Performance evaluation of an improved optical computed tomography polymer gel dosimeter system for 3D dose verification of static and dynamic phantom deliveries (2008)

The performance of a next-generation optical computed tomography scanner (OCTOPUS-5X) is characterized in the context of three-dimensional gel dosimetry. Large-volume (2.2 L), muscle-equivalent, radiation-sensitive polymer gel dosimeters (BANG-3) were used. Improvements in scanner design leading to shorter acquisition times are discussed. The spatial resolution, detectable absorbance range, and reproducibility are assessed. An efficient method for calibrating gel dosimeters using the depth-dose relationship is applied, with photon- and electron-based deliveries yielding equivalent results. A procedure involving a preirradiation scan was used to reduce the edge artifacts in reconstructed images, thereby increasing the useful cross-sectional area of the dosimeter by nearly a factor of 2. Dose distributions derived from optical density measurements using the calibration coefficient show good agreement with the treatment planning system simulations and radiographic film measurements. The feasibility of use for motion (four-dimensional) dosimetry is demonstrated on an example comparing dose distributions from static and dynamic delivery of a single-field photon plan. The capability to visualize three-dimensional dose distributions is also illustrated.
Significance of Acellular Mucin Pools in Rectal Carcinoma After Neoadjuvant Chemoradiotherapy (2010)

The presence of mucin pools lacking neoplastic epithelium ("acellular" mucin) in resection specimens of rectal carcinoma after neoadjuvant chemoradiotherapy (CRT) is a well-recognized phenomenon. The current recommendation by the College of American Pathologists is to regard acellular mucin as a type of treatment response and not as residual tumor. However, data-based evidence for or against such an approach is incomplete. In this study, we systematically analyzed the pattern and significance of mucin pools in 108 consecutive, prospectively collected resection specimens from patients who had uT3-4 and/or uN1 rectal cancer and were treated with preoperative long-course CRT. The 108 patients, 39 female and 69 male, had a median age of 58.5 years. With every tumor entirely examined in whole-mount sections, mucin pools were identified in 33 cases (33 of 108, 31%); in 16 (15%) they were all acellular. The mucin pools were focal (10% to 50% of the entire lesion) in 25 cases and extensive (>50%) in 8 cases. Mucin pools were also noted in the lymph nodes in 6 cases (6%); 3 of these were entirely acellular. Five cases had mucin pools in both the primary site and the lymph nodes. When acellular mucin was considered as "no residual tumor," the complete pathologic response rate for the entire cohort was 22% (24 of 108). The pathologic stage of the residual tumor (ypT) was 0 or 1 for 27 cases (25%) and 2 to 4 for 81 cases. The pathologic stage of nodal disease (ypN) was 0 for 83 (77%) and 1 or 2 for 25 cases. When acellular mucin was considered as "residual tumor," the complete pathologic response rate dropped to 17%; ypT was upstaged in 10 tumors and ypN was upstaged in 2 tumors. With a median follow-up of 31 months, the 3-year recurrence-free survival (RFS) was 73% for the entire group. Advanced pathologic response and low pathologic stage of the residual tumor (determined based on the depth of only viable tumor cells) correlated significantly with better RFS. However, the correlation between pathologic response and RFS became insignificant when acellular mucin pools were considered as residual tumor. Neither the presence of mucin pools nor their extent or cellularity had an impact on RFS. Furthermore, none of the 12 patients whose ypT or ypN was upstaged by acellular mucin had recurrent disease (3-y RFS of 100%). Thus, our results suggest that mucin pools in rectal carcinoma after neoadjuvant CRT do not have a significant impact on patient outcome, supporting the College of American Pathologists recommendation that only viable tumor cells, not acellular mucin, are to be interpreted as residual disease in the tumor pathologic staging.
Probing the properties of planetary ring dust by the observation of Mach cones (1995)

Compressive dust acoustic waves can be excited in dusty plasmas. Big boulders in planetary rings move at the Keplerian velocity, while smaller dust particles move at a slightly different velocity due to the action of the Lorentz force. If the difference in velocity Δυ is larger than the dust acoustic wave velocity, α d , a wake will be formed with an opening angle of 2θ where sin θ = |α d /Δυ|. The discovery of wakes and the measurement of their opening angles by the space experiment Cassini to Saturn will yield added information on the dusty plasma conditions in regions through which Cassini will not pass. We find that in some regions the waves that are excited by the boulders may be weak because a large fraction of the interacting dust is absorbed rather than deflected by the boulder. For a given dust size the most favourable conditions for the observations of wakes exist in two fairly narrow regions, one inside and one outside the corotation radius. The favorable regions are closest to the corotation radius for the smallest dust particles and progressively further away for larger dust particles.
Bound Estimates of the Severity of Line Outages in Power System Contingency Analysis and Ranking (1984)

The effect of line outages on the real power flows of a system is analyzed using the DC load flow model. It is shown that the effect of the out4ge of line jk on the power flow of an arbitrary line lm can be bounded above and below by a series of progressively tighter values which in the limit correspond to the exact DC load flow solution. The calculation of these bound estimates on the contingency line flows is progressively more computationally demanding as the limits tighten, however, the simple to compute bounds, although more conservative, still serve to filter out a large portion of the non-critical contingencies. The remaining few potentially critical outages can then be ranked and analyzed through the full DC load flow.

2,4-Dioxatricyclo[3.3.1.13,7]decane, a unique acetal with both oxygens axial on tetrahydropyran rings, is formed spontaneously when all-cis 3,5-dihydroxy-1-cyclohexaneacetaldehyde is generated in acid.
Immunologic Responses in Human Recipients of Osseous and Osteochondral Allografts (1996)

A multiinstitutional study was carried out to evaluate immunologic responses for human recipients of massive frozen (-80 degrees C) osseous and osteochondral allografts. Allografts were used to reconstruct skeletal defects associated with a variety of traumatic degenerative and neoplastic disorders. Serum samples were obtained before surgery and from 1 month to 4 years after surgery. Sera were tested by microcytotoxicity against T cells from 60 donors for human leukocyte antigen Class I antibodies and against beta 2-microglobulin treated B cells from 40 donors for human leukocyte antigen Class II antibodies. Panels were selected to represent the majority of known human leukocyte antigen specificities. Of the 84 cases evaluated, 62 (74%) received blood transfusions and 28 of 44 (64%) female recipients had been previously pregnant. Sensitization before transplant was shown in 33 of 84 (39%) patients. After grafting, 49 of 84 (58%) recipients showed evidence of sensitization to Class I antigens and 46 of 84 (55%) recipients showed evidence to sensitization to Class II antigens. Overall sensitization was 67%.

A highly expressed 81 kDa protein in immortalized mouse fibroblast: its proliferative function and identity with ezrin. (1996)

An 81 kDa protein was found to be highly expressed in spontaneously immortalized CD1-ICR mouse fibroblasts, RS-4, as compared to normal fibroblasts. RS-4 cells have a reduced serum requirement and exhibit multilayered growth in vitro but are not tumorigenic. The protein was purified from RS-4 cell extracts and used to obtain a polyclonal antibody that specifically immunoprecipitated an 81 kDa protein from cell lysates. Immunocloning of its cDNA and sequence analysis revealed its identity with ezrin, an F-actin binding protein that is a component of the cortical cytoskeleton. Microinjection of the purified IgG fraction of the anti-p81 antiserum into the cytoplasm of RS-4 cells blocked their entry into S phase suggesting that the protein has a proliferative function. Immunostaining of normal mouse tissues showed that the expression of p81/ezrin was highest in proliferating cell populations. Unlike RS-4, NIH3T3 cells exhibit contact inhibition and express levels of p81/ezrin similar to those of normal fibroblasts. When NIH3T3 cells were transfected with p81/ezrin cDNA they lost contact inhibition and thus resembled RS-4 cells. The study demonstrates a proliferative function of p81/ezrin and suggests its involvement in pathways that negatively regulate contact inhibition.

Melanocortin 4 receptor stimulation decreases pancreatitis severity in rats by activation of the cholinergic anti-inflammatory pathway* (2011)

Nutritional survey on the serum status of lipid, protein, and calcium levels in Nepalese. (1990)

This study examined the physical status (72 males and 69 females) and serum distribution of lipids, protein, and Ca (60 males and 57 females) of people aged 1 to 72 years living in southeastern Nepal. The mean values of height and weight increased with age to adolescence and were the same for both sexes in childhood. Males were taller than females above the 15-19-year age group. There were large weight differences among individuals, with adult males tending to be heavier than adult females. The average body mass index increased with age (r=0.72, p<0.001), and there were no significant differences between the sexes. The levels of body mass index were positively correlated with weight (r=0.92, p<0.001) and with serum levels of cholesterol and triglycerides (r=0.43, and r=0.38, p<0.001, respectively). The levels of serum lipids were about the same for both sexes in childhood and tended to be higher for males than for females in adulthood. Serum levels of cholesterol, phospholipids, and total lipids were positively correlated with age (r=0.46, r=0.36, and r=0.37, p<0.001, respectively). A direct relationship was found between the levels of cholesterol and triglycerides (r=0.46, p<0.001). The mean levels of protein and Ca in serum were similar for both sexes for all ages examined (7.82 and 8.02g/100ml for protein and 10.6 and 10.3mg/100ml for Ca, for males and females, respectively). The protein levels showed a correlation with Ca (r=0.30, p<0.001). Based on the above findings, we conclude that the Nepalese tend to have higher serum levels of TG and to have serum protein and Ca levels similar to what is considered the normal range for inhabitants of developed countries.
The quantitation of electron energy loss spectra (1981)

SUMMARY An interactive computer program which allows the quantitation of electron energy loss spectra is described. The program performs a standardless analysis using hydrogenic cross‐section models. The accuracy of the results obtained for a wide range of experimental conditions is typically within 20% of expected values for well characterized samples. The lack of agreed thin film standards is a limit to the improvement of the cross‐section models, but under most practical operating conditions the largest errors arise from instrumental factors such as the effect of finite beam convergence and chromatic errors in the coupling optics.

Oxidative C−C Bond Cleavage of Primary Alcohols and Vicinal Diols Catalyzed by H<sub>5</sub>PV<sub>2</sub>Mo<sub>10</sub>O<sub>40</sub>by an Electron Transfer and Oxygen Transfer Reaction Mechanism (2008)

Primary alcohols such as 1-butanol were oxidized by the H5PV2Mo10O40 polyoxometalate in an atypical manner. Instead of C-H bond activation leading to the formation of butanal and butanoic acid, C-C bond cleavage took place leading to the formation of propanal and formaldehyde as initial products. The latter reacted with the excess 1-butanol present to yield butylformate and butylpropanate in additional oxidative transformations. Kinetic studies including measurement of kinetic isotope effects, labeling studies with 18O labeled H5PV2Mo10O40, and observation of a prerate determining step intermediate by 13C NMR leads to the formulation of a reaction mechanism based on electron transfer from the substrate to the polyoxometalate and oxygen transfer from the reduced polyoxometalate to the organic substrate. It was also shown that vicinal diols such as 1,2-ethanediol apparently react by a similar reaction mechanism.
Development of a New Nickel Containing Alloy for Flexible Exhaust Couplings (1998)

Abstract In automotive exhaust flexible coupling applications commonly used stainless steels have failed by hot salt corrosion, stress corrosion cracking, pitting and fatigue with associated sensitization resulting from the high temperature exposure. This paper describes the development of an alloy designed specifically to overcome these failure mechanisms while maintaining good weldability and thermal stability.
Detection of Epileptic Seizure Using Wireless Sensor Networks (2013)

The monitoring of epileptic seizures is mainly done by means of electroencephalogram (EEG) monitoring. Although this method is accurate, it is not comfortable for the patient as the EEG-electrodes have to be attached to the scalp which hampers the patient's movement. This makes long-term home monitoring not feasible. In this paper, the aim is to propose a seizure detection system based on accelerometry for the detection of epileptic seizure. The used sensors are wireless, which can improve quality of life for the patients. In this system, three 2D accelerometer sensors are positioned on the right arm, left arm, and left thigh of an epileptic patient. Datasets from three patients suffering from severe epilepsy are used in this paper for the development of an automatic detection algorithm. This monitoring system is based on Wireless Sensor Networks and can determine the location of the patient when a seizure is detected and then send an alarm to hospital staff or the patient's relatives. Our wireless sensor nodes are MICAz Motes developed by Crossbow Technology. The proposed system can be used for patients living in a clinical environment or at their home, where they do only their daily routines. The analysis of the recorded data is done by an Artificial Neural Network and K Nearest-Neighbor to recognize seizure movements from normal movements. The results show that K Nearest Neighbor performs better than Artificial Neural Network for detecting these seizures. The results also show that if at least 50% of the signal consists of seizure samples, we can detect the seizure accurately. In addition, there is no need for training the algorithm for each new patient.
Measurement of the magnetic field profile in the atomic fountain clock FoCS-2 using Zeeman spectroscopy (2016)

We report the evaluation of the second order Zeeman shift in the continuous atomic fountain clock FoCS-2. Because of the continuous operation and of its geometrical constraints, the methods used in pulsed fountains are not applicable. We use here time-resolved Zeeman spectroscopy to probe the magnetic field profile in the clock. The pulses of ac magnetic excitation allow us to spatially resolve the Zeeman frequency and to evaluate the Zeeman shift with a relative uncertainty smaller than 10E-16.

Fusion rings arising from normal Hopf subalgebras (2009)

For any normal commutative Hopf subalgebra $K=k^G$ of a semisimple Hopf algebra we describe the ring inside $kG$ obtained by the restriction of $H$-modules. If $G=\Z_p$ this ring determines a fusion ring and we give a complete description for it. The case $G=\Z_{p^n}$ and some other applications are presented.
Electron loss to the continuum for H<sub>2</sub><sup>+</sup>and He<sup>+</sup>ions colliding with H<sub>2</sub>, He, Ne and Ar. I. Electron cusp widths and shapes (1986)

Differential spectra for electron production in the forward direction have been obtained by collision of H2+ and He+ ions with H2, He, Ne and Ar gases. The measurements where made with ions of energy 0.8-2.8 MeV. The target consisted of a jet of gas from a multicapillary array, thereby providing a well localised and directed gas beam. A 30 degrees parallel-plate electrostatic analyser having a FWHM resolution (dE/E)=10-3 was used to study the energy of the ejected electrons. A cusp-shaped peak centred on ve=vi was observed for all the electron spectra, suggesting that these electrons were ejected with only a small energy relative to the parent ions. This process has been called electron loss to the continuum (ELC) since in some ways it mimics the now well established phenomenon of charge exchange to the continuum (CEC). In contrast to data for ELC from heavy ions the cusps observed here were generally asymmetric. They did, however, show a width approximately independent of projectile velocity, a feature which seems to distinguish ELC from CEC. Both the cusp shapes and widths are compared with theoretical predictions and other experimental measurements.

Molecular dynamics of the wetting and drying of a wall with a long-ranged wall-fluid interaction (1992)

The authors have studied the influence of a long-ranged force between a wall and a fluid on the wetting properties of the wall-fluid system. The system with short-ranged forces, i.e. cut-off Lennard-Jones potentials only, has been studied extensively in previous simulations, revealing the presence of a wetting and a drying transition. The authors have increased the cut-off radius of the wall-fluid potential by a factor of 5 in the simulations and re-inspected these transitions. The wetting transition turns out not to be much affected by the long-ranged potential but the drying transition is suppressed.
