Numerical Modelling and Analysis of Hydrostatic Thrust Air Bearings for High Loading Capacities and Low Air Consumption (2017)

The paper presents a numerical simulation study on hydrostatic thrust air bearings to assess the load capacity, compressed air consumptions, and the dynamic response. Finite Difference Method (FDM) and Finite Volume Method (FVM) are combined to solve the non-linear Reynolds equation to find the pressure distribution of the air bearing gas film and the total loading capacity of the bearing. The influence of design parameters on air film gap characteristics, including the air film thickness, supplied pressure, depth of the groove and external load, are investigated based on the proposed FDM model. The simulation results show that the thrust air bearings with a groove have a higher load capacity and air consumption than without a groove, and the load capacity and air consumption both increase with the depth of the groove. Bearings without the groove are better damped than those with the grooves, and the stability of thrust bearing decreases when the groove depth increases. The stability of the thrust bearings is also affected by their loading.
Superparamagnetic iron oxide: clinical application as a contrast agent for MR imaging of the liver. (1988)

Superparamagnetic iron oxide (ferrite) particles were evaluated as a contrast agent for magnetic resonance (MR) imaging. In this pilot study, doses ranging from 10 to 50 mumol/kg were administered intravenously to 15 patients. Ferrite-enhanced images of the liver obtained with standard pulse sequence techniques significantly increased the number of hepatic lesions detected (P less than .01) and reduced the threshold size for detection to 3 mm (P less than .01). The improved clinical performance of ferrite-enhanced images correlated with significant increases in measured contrast-to-noise ratios (P less than .01). Degradation of superparamagnetic activity and/or clearance of ferrite from the liver was demonstrated as early as 12 hours after injection, suggesting that the lack of chronic toxicity observed in animal studies may be reproduced in humans. These initial clinical results appear to confirm extensive preclinical data indicating that ferrite administered at a dose of 20 mumol/kg has the potential to significantly improve the performance of abdominal MR imaging.
Projection receiver: a new efficient multi-user detector (1995)

A new multi-user receiver for synchronous coded CDMA systems is proposed that removes the multi-user interference (MUI) by projecting the interfering users onto the signal space of the desired users, i.e., chooses the least mean squares (LMS) estimate of the interfering users. This results in an adjusted metric for decoding of the desired user(s) which is (are) decoded via maximum-likelihood sequence estimation (MLSE). Simulation results confirm superior system performance, using only a single user decoder.
Modem IC Supports Three 1200 BPS Standards (1985)

The popularity of personal computers have created a greater need for more efficient and inexpensive communication methods between computers. The existence of different protocols made the problem more complex. This paper recommends a solution by using an IC modem device that supports the three major 1200 bps protocols. This paper also discusses the design flexibility achieved by using such a modem device.
Optical and local current studies on InAs/GaAs quantum dots (2006)

By optimizing the growth technique of molecular beam epitaxy (MBE), we've prepared high quality InAs quantum dot samples, with high density (up to 1.2 x 10<sup>11</sup> cm<sup>-2</sup>) and highly homogeneous size. Strong room temperature photoluminescence (PL) have been observed. The PL study reveals four confined-states QD transitions, which shows filling effect of the excited states. Dependence of these recombinations on excitation intensity and temperature has also been investigated. Conductive atomic force microscopy (C-AFM) has been used to probe the local current of InAs surface quantum dots (SQDs) on doped GaAs layer. It is found that current about picoampere can be drawn from individual QD while bias of a few hundred mV is applied between tip and the sample. Further I-V studies discover that surface quantum dots usually has a threshold bias near 200 mV for current transmission, whereas bias of 400 mV is needed when the conductive tip is located on wetting layer.

Application of A.C. potential drop technique to measure the stress-intensity factor. (1990)

An a.c. potential drop technique is applied for measurement of the stress-intensity factor, K1. When a conductive material with a surface crack is loaded under a flow of a.c., a change occurs in electrical potential difference between two points located on either side of the surface separated by the crack. By measuring the change for different loadings, it is found that the change shows a linear relationship with the change in K1. Also, the relationship is revealed to be independent of the crack depth. A.c. in the amount of 1 ampere with a frequency of 10kHz is used. Finally, a procedure for applying the present result to an in situ measurement of K1 is proposed and verified.

PHYSICS DIVISION SUMMARY REPORT, SEPTEMBER-OCTOBER 1962 (1963)

the isomeric transition was dominated by spectra of multiply-charged atomic species, whereas the pattern due to Br/sup 82/ was entirely made up of singlycharged products. An investigition of nondiagonal matrix elements arising in a shell-model treatment of a deformed nucleus showed that their neglect in determining the degree of deformation does not lead to serious error. A previous statement, in a study of collective effects and the shell model, about K = 0 bands in odd-odd nuclei is corrected. The effect of residual interactions is calculated, and the result is applied to Ho/sup 166/. (For preceding period see ANL-6190.) (W.D.M.)
Common antigenic domains in transferrin-binding protein 2 of Neisseria meningitidis, Neisseria gonorrhoeae, and Haemophilus influenzae type b (1992)

There is now considerable evidence to show that in the Neisseria and Haemophilus species, membrane receptors specific for either transferrin or lactoferrin are involved in the acquisition of iron from these glycoproteins. In Neisseria meningitidis, the transferrin receptor appears to consist of two proteins, one of which (TBP 1) has an M(r) of 95,000 and the other of which (TBP 2) has an M(r) ranging from 68,000 to 85,000, depending on the strain; TBP 2 binds transferrin after sodium dodecyl sulfate-polyacrylamide gel electrophoresis and electroblotting, but TBP 1 does not do so. The relative contributions of these two proteins to the binding reaction observed with intact cells and to iron uptake are presently unknown. However, they are being considered as potential components of a group B meningococcal vaccine. Analogous higher- and lower-molecular-weight proteins associated with transferrin binding have been found in N. gonorrhoeae and Haemophilus influenzae. Previous work with polyclonal antibodies raised in mice with whole cells of iron-restricted N. meningitidis showed that the meningococcal TBP 2 exhibits considerable antigenic heterogeneity. Here, we report that antiserum against purified TBP 2 from one strain of N. meningitidis cross-reacts on immunoblotting with the TBP 2 of all meningococcal isolates examined, as well as with the TBP 2 of N. gonorrhoeae. This antiserum also cross-reacted with the TBP 2 of several strains of H. influenzae type b, thus showing the presence of common antigenic domains among these functionally equivalent proteins in different pathogens; no cross-reaction was detected with a purified sample of the human transferrin receptor.

Homodyne detection technique using spontaneously generated reference signal in picosecond thermoreflectance measurements (2003)

A new detection technique for picosecond thermoreflectance measurements has been developed. Conventional picosecond thermoreflectance measurements detect the signal amplitude of a reflected probe laser beam synchronized with the modulation frequency of the pump laser beam using a lock-in amplifier. Our new detection technique uses the signal phase of the lock-in output instead of the signal amplitude. Thermoreflectance signals for molybdenum thin films deposited on glass substrates were observed at room temperature. The signal-to-noise ratio of the phase detection was about four times better than that of the amplitude detection. The signal phase detected by this model is insensitive to fluctuation of both pump and probe beams. According to this technique, picosecond thermoreflectance measurements can apply not only to single layer metal thin films of around 100 nm thickness, but also to thicker metal films, metal–nonmetal multilayer thin films, and many other thin films.
Filter flow (2009)

The filter flow problem is to compute a space-variant linear filter that transforms one image into another. This framework encompasses a broad range of transformations including stereo, optical flow, lighting changes, blur, and combinations of these effects. Parametric models such as affine motion, vignetting, and radial distortion can also be modeled within the same framework. All such transformations are modeled by selecting a number of constraints and objectives on the filter entries from a catalog which we enumerate. Most of the constraints are linear, leading to globally optimal solutions (via linear programming) for affine transformations, depth-from-defocus, and other problems. Adding a (non-convex) compactness objective enables solutions for optical flow with illumination changes, space-variant defocus, and higher-order smoothness.

Second-order analytical modeling of thin-film SOI MOSFETs (2003)

Summary form only given. The authors discuss the importance and the modeling of some characteristics of thin-film SOI MOSFETs related to second-order physical effects. To assess the importance of these second-order effects, they have been incorporated in an analytical model developed for long channel SOI MOSFETs in linear operation. The model remains valid whether the SOI film is fully or partially depleted. The derivation of the model is presented. Comparisons with experimental measurements clearly demonstrate the larger range of applicability and the improved physical accuracy of the model. The influence of the second-order effects are determined by comparing theoretical results of first-order analyses and of the improved model; both analyses were realized using the same set of model parameters. The analysis clearly shows that a thin-film SOI MOSFET cannot be considered a fully depleted device over its whole range of operation. Such an approximation could also lead to dramatic mismodelings of the overall physical behavior of the device.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Nonlinear interactions between relativistic electrons and ultrahigh intensity laser pulses in vacuum (1997)

Different nonlinear interactions between relativistic electrons and ultrahigh intensity laser pulses in vacuum are considered. We first briefly review the wave equation in vacuum to described the three-dimensional laser field distribution at focus, including longitudinal field components, and discuss the accuracy of the paraxial wave equation and its Gaussian spherical solutions. The effect of radiation pressure on the Doppler-shifted radiation scattered by the electrons is then discussed for plane waves, and the corresponding nonlinear spectra are presented. We also introduce the concept of temporal laser beam shaping, and show how it can alleviate the nonlinear Doppler shift problem. At high energies, radiation reaction plays an important role in the electron dynamics, and is briefly discussed within the context of the classical Dirac-Lorentz equation.
On the presence of serotonin in cerebrovascular sympathetic nerves and the interaction with noradrenaline at specific receptors mediating vasoconstriction. (1988)

Immunohistochemical and pharmacological studies have been performed on rat, guinea-pig, and monkey in order to elucidate serotonergic mechanisms in the cerebrovascular bed. The results provide strong evidence that 5-hydroxytryptamine is present together with noradrenaline in perivascular sympathetic nerves, which also contain neuropeptide Y. Sympathetic nerve activation induces a co-release of 5-hydroxytryptamine, which markedly potentiates the vasoconstrictor action of noradrenaline via specific serotonergic receptors. These receptors are of the same kind as those mediating the postjunctional contractile effect of 5-hydroxytryptamine. This observation of a new type of amine transmitter coexistence in sympathetic nerve fibres may help to understand the powerful vasoconstrictory potency of 5-hydroxytryptamine in the brain vasculature, and thereby increase our knowledge about the pathophysiological role of this amine in serious clinical disorders, such as migraine, stroke, and vasospasm following subarachnoid hemorrhage.

Expression of 4C8 antigen, a novel transendothelial migration‐associated molecule on activated T lymphocytes, in inflammatory bowel disease (2002)

Recruitment of peripheral leukocytes to intestine is an essential process for intestinal inflammation. This study examined the localization of a novel molecule, 4C8 antigen, in inflammatory bowel disease; this molecule is involved in the transendothelial migration of T lymphocytes. Surgical specimens of human intestine were obtained from nine patients with ulcerative colitis, 13 with Crohn's disease, and eight controls. Immunohistological staining was performed using antibodies against 4C8 antigen, and CD3, CD4, CD8, CD20, CD68, CD45RA, CD45RO, CD11a, and CD62 (E- and P-selectin) by the peroxidase method. Immunological double staining was subsequently performed for the same specimens stained with anti-4C8 antibody using the alkaline phosphatase method. In normal controls, 4C8-positive cells were mainly found in lamina propria. 4C8-positive cells were increased in lamina propria and submucosa of specimens with Crohn's disease. Accumulation of 4C8-positive cells surrounding CD62-positive vessels was found in the submucosa of specimens with inflammatory bowel disease, but not in controls. Immunohistological double staining revealed that the major subsets of 4C8-positive cells were positive for CD3, CD4, CD45RO, and CD11a. 4C8-positive cells in human intestine belong to the subset of helper/inducer memory T cells newly recruited from the peripheral pool. Inhibition of the 4C8-ligand system could have potentially uses in the treatment of inflammatory bowel disease.

Combinatorial Message Sharing and a New Achievable Region for Multiple\n Descriptions (2015)

This paper presents a new achievable rate-distortion region for the general L\nchannel multiple descriptions problem. A well known general region for this\nproblem is due to Venkataramani, Kramer and Goyal (VKG) [1]. Their encoding\nscheme is an extension of the El-Gamal-Cover (EC) and Zhang- Berger (ZB) coding\nschemes to the L channel case and includes a combinatorial number of refinement\ncodebooks, one for each subset of the descriptions. As in ZB, the scheme also\nallows for a single common codeword to be shared by all descriptions. This\npaper proposes a novel encoding technique involving Combinatorial Message\nSharing (CMS), where every subset of the descriptions may share a distinct\ncommon message. This introduces a combinatorial number of shared codebooks\nalong with the refinement codebooks of [1]. We derive an achievable\nrate-distortion region for the proposed technique, and show that it subsumes\nthe VKG region for general sources and distortion measures. We further show\nthat CMS provides a strict improvement of the achievable region for any source\nand distortion measures for which some 2-description subset is such that ZB\nachieves points outside the EC region. We then show a more surprising result:\nCMS outperforms VKG for a general class of sources and distortion measures,\nincluding scenarios where the ZB and EC regions coincide for all 2-description\nsubsets. In particular, we show that CMS strictly improves on VKG, for the\nL-channel quadratic Gaussian MD problem, for all L greater than or equal to 3,\ndespite the fact that the EC region is complete for the corresponding\n2-descriptions problem. Using the encoding principles derived, we show that the\nCMS scheme achieves the complete rate-distortion region for several asymmetric\ncross-sections of the L-channel quadratic Gaussian MD problem.\n
LASER BASED SURFACE PROCESSING OF ENGINEERING MATERIALS - STATE OF ART (2008)

An overview is given on the state of art of the laser based surface processing of engineering materials. In major engineering application surface of the material plays a major role. since the surface has the direct contact with the environment as well as the load. The different parameters such as hardness, toughness, wear resistance etc on the surface has to be enhanced based on the application, hence there is a need to go for surface processing. Conventional surface processing has its own limitations toward recently developed materials and other functional aspects. These aspects can be overcome by laser based surface processing. In this paper an attempt has been made to investigate the principal and effect of laser interaction on materials such as heating, surface melting, vaporization, plasma formation , ablation etc .The different types of laser based surface processing of engineering materials based on their properties, Processing parameters and functional aspects which is considered for different application has been discussed.
Phosphorus-Bridged [1.1]Ferrocenophane with syn and anti Conformations (2005)

Photolysis of PPh-bridged [1]ferrocenophane (1) in THF gave PPh-bridged [1.1]ferrocenophane (2) as a minor dimer along with major polymeric products. After subsequent sulfurization of the reaction mixture with elemental sulfur, both syn and anti isomers of P(S)Ph-bridged [1.1]ferrocenophane (3) were successfully isolated and characterized by X-ray analysis. syn-3 thus obtained was desulfurized stereoretentively to syn-2 with Si2Cl6 in refluxing benzene, while anti-3 primarily gave the isomerized product, syn-2. Stereoretentive desulfurization of anti-3 to anti-2 was achieved with CF3SO3Me/P(NMe2)3 at room temperature. anti-2 thus obtained could be converted almost completely to syn-2 upon simple heating in toluene, indicative of the thermal instability of the anti isomer over the syn isomer. The yield of syn-2 was improved from 9% to 32% when THF used in the photolysis was replaced with ether and the reaction mixture was heated so as to isomerize anti-2, which had been formed concomitantly. A potential utility of syn-2 as a ligand was demonstrated by the formation of [CoCl2(syn-2)] (5) through a reaction of syn-2 with CoCl2.
Shape memory alloy–based biopsy device for active locomotive intestinal capsule endoscope (2015)

Recently, capsule endoscopes have been used for diagnosis in digestive organs. However, because a capsule endoscope does not have a locomotive function, its use has been limited to small tubular digestive organs, such as small intestine and esophagus. To address this problem, researchers have begun studying an active locomotive intestine capsule endoscope as a medical instrument for the whole gastrointestinal tract. We have developed a capsule endoscope with a small permanent magnet that is actuated by an electromagnetic actuation system, allowing active and flexible movement in the patient's gut environment. In addition, researchers have noted the need for a biopsy function in capsule endoscope for the definitive diagnosis of digestive diseases. Therefore, this paper proposes a novel robotic biopsy device for active locomotive intestine capsule endoscope. The proposed biopsy device has a sharp blade connected with a shape memory alloy actuator. The biopsy device measuring 12 mm in diameter and 3 mm in length was integrated into our capsule endoscope prototype, where the device's sharp blade was activated and exposed by the shape memory alloy actuator. Then the electromagnetic actuation system generated a specific motion of the capsule endoscope to extract the tissue sample from the intestines. The final biopsy sample tissue had a volume of about 6 mm(3), which is a sufficient amount for a histological analysis. Consequently, we proposed the working principle of the biopsy device and conducted an in-vitro biopsy test to verify the feasibility of the biopsy device integrated into the capsule endoscope prototype using the electro-magnetic actuation system.
