Exercise Training-Induced Blood Pressure and Plasma Lipid Improvements in Hypertensives May Be Genotype Dependent (1999)

Exercise training improves cardiovascular disease risk, but individual responses are highly variable. We hypothesized that common polymorphic gene variations would affect these responses. Sedentary obese hypertensive older men who had undergone exercise training were typed at the apolipoprotein (apo) E, angiotensin-converting enzyme (ACE), and lipoprotein lipase (LPL) loci. Individuals of all genotype subgroups were generally similar before training; they also changed body weight, body composition, and &f1;O(2)max similarly with training. ACE insertion/insertion (II) and insertion/deletion (ID) genotype individuals (n=10) tended to reduce systolic blood pressure more with training than deletion/deletion (DD) individuals (n=8) (-10 versus -5 mm Hg, P=0. 16). ACE II and ID individuals decreased diastolic blood pressure more with training than DD individuals (-10 versus -1 mm Hg, P<0. 005). Systolic blood pressure reductions with training were also larger in apoE3 and E4 (n=15) than apoE2 men (n=3) (-10 versus 0 mm Hg, P<0.05). The same trend was evident for diastolic blood pressure (-7 versus -3 mm Hg), but the difference was not significant. Systolic (14 versus -6 mm Hg, P=0.08) and diastolic (-9 versus -5 mm Hg, P=0.10) blood pressure reductions tended to be greater in LPL PvuII +/+ (n=4) than +/- and -/- individuals (n=14). Systolic (-10 versus 3 mm Hg, P<0.05) and diastolic (-9 versus 2 mm Hg, P<0.05) blood pressure reductions were larger in LPL HindIII +/+ and +/- (n=15) than -/- persons (n=3), respectively. LPL PvuII -/- individuals (n=3) had larger increases in HDL cholesterol (11 versus 2 mg/dL, P<0.05) and HDL(2) cholesterol (8 versus 0 mg/dL, P<0.05) than LPL PvuII +/- and +/+ individuals (n=15). These results are consistent with the possibility that apoE, ACE, and LPL genotypes may identify hypertensives who will improve blood pressure, lipoprotein lipids, and cardiovascular disease risk the most with exercise training.
Stimulated emission and emission efficiency enhancement in nanopatterned silicon (2007)

1.278&mu;m laser emission has been observed in a SOI structure which has been nanopatterned to contain an array of nanopores. The optical transition is identified to be associated with phononless recombination mediated by the bistable, carbon-related G center. The present work is focused on increasing the luminescence intensity from nanopatterned Si by increasing the number of G centers present in the material. The G center density is increased by increasing the concentration of substitutional atoms in the lattice prior to nanopatterning. To this end, solid-phase epitaxial regrowth of carbon-rich silicon is utilized in order to take advantage of the increased solid solubility of carbon in silicon at the interface between crystalline and amorphous solid silicon.
Audio Program Interchange: Networks, File Formats, and Real-Time Transfer (1993)

&lt;p&gt;Digital audio program material may be transferred from one system or location to another using a variety of methods. Recording media, such as disks and tapes, may be physically transported, but there are compatibility problems between systems; real-time interfaces may be used to replace analog interconnections for signal routing, and computer-style networks may be used for the transfer of audio in the form of data files. The relative merits of different approaches to program interchange with reference to operational requirements, and the various problems of data format and compatibility are examined.&lt;/p&gt;
Interpretation of two photon absorption driven nonlinear absorption (2005)

Extensive measurements and modeling of several two photon absorbing materials are described. These are used to elucidate the relative significance of various relaxation and excitation processes that come into play in nonlinear transmission (NLT) and two photon absorption cross section measurements. A reliable measurement of the one photon absorption cross sections at energies 0.5 to ~1.7 eV below the fundamental transition are presented with Voigt function fits that enable the determination of the Gaussian and Lorentzian line widths. Both a numerical model and an analytical model are developed neither of which use any adjustable parameters in comparing calculated NLT results to data. Both models fit the data relatively well over the full range of the experiment. The analytical model captures the primary causes of the nonlinear absorption in the low intensity regime and demonstrates that the nonlinear transmittance can be estimated as a simple effective three-photon process. The numerical model calculates the spatial and time dependence of three state populations and all of the transitions between these states. This model improves the quality of the nonlinear transmission fit which is due to the inclusion of the ground state absorption. Additionally an observation of a strong, long lived transient which is quenched by oxygen suggests multiphoton ionization is happening at low intensities. Thus the full range of constraints applicable to all measurements of the two photon cross section are presented.
536 The Effect of Oil Mist on the Machinability in Turning of Super Heat-Resistant Alloy Inconel 718 (2003)

The purpose of this study is to clarify the potential of the eco-cutting process for the super heat-resistant alloy Inconel 718. Experimental cutting by turning has been conducted to find ways to improve the efficiency of difficult-to-machine materials such as the super heat-resistant alloy Inconel 718. The techniques of the cutting process applied in the experiments include dry cutting, wet cutting with an emulsion coolant, oil-mist cutting, and cool air cutting as well as cutting with a mixture of oil-mist and cool air. During the cutting experiment, cemented carbide tools were used for turning the periphery of round bars. Based on the experimental results, it was found that by using a mixture of vegetable oil-mist and cool air, an equivalent effect of machinability as that obtained using the emulsion coolant was determined.
Design of the Solenoid Valve of an Antilock Braking System With Reduced Flow Noise (2017)

Large eddy simulations are carried out to predict the flow noise produced in the solenoid valve of an antilock braking system (ABS) using Lighthill’s acoustic analogy and the Ffowcs Williams and Hawkings (FW–H) surface integral method. The fluid inside the valve is assumed to be incompressible at a fixed temperature. The solenoid valve operation is realized by applying an overset grid methodology to the moving plunger, and the plunger has a linear motion in the axial direction. Several types of solenoid valves are numerically designed to maximally reduce the flow noise. The upstream flow is detached through a small opening between the plunger and the seat, which generates pressure fluctuation around the narrow gap, which is subject to high wall pressure fluctuations and shear stresses. Large eddy simulations are performed by varying the position of the flow separation. An optimal design of the valve is obtained, featuring a small radius of surface curvature, a smooth surface, and a large plunger tip area angle. Measurements are obtained from the optimal design to validate the design in a real vehicle performance test, and the predicted pressure frequency in the solenoid valve agreed well with the experimental results.
Prostaglandin E <sub>2</sub> Production After Lamellar Keratectomy and Photorefractive Keratectomy (1994)

Mechanical and photochemical superficial keratectomies induce production of an inflammatory mediator, PGE2. The 193-nanometer excimer laser irradiation causes a greater increase of PGE2 production in the corneal tissue than does keratectomy with the microkeratome; this observation may support a role for cyclo-oxygenase inhibitors in postoperative therapy.
Organ culture of the trigeminal ganglion induces enhanced expression of calcitonin gene-related peptide via activation of extracellular signal-regulated protein kinase 1/2 (2010)

We suggest that in conditions of elevated CGRP expression, inhibition of ERK1/2 might be an option for novel treatment.
&lt;title&gt;Autonomous Observer: a tool for remote experimentation in robotics&lt;/title&gt; (1999)

This paper describes a robotics technology--the Autonomous Observer (AO)--developed to facilitate experimentation over the Internet. The AO is a mobile robot equipped with visual sensors. It applies visual tracking and motion planning techniques to track a designated moving object (the target) in an environment cluttered by obstacles and repeatedly measure the target's pose. This pose is sent over the Internet to remote users who can observe 3D real-time graphic renderings of the target's motion in its environment under individually selected viewpoints. The AO was used to set up an experiment in which a can-collecting robot (playing the role of the target) equipped with a range sensor and a simple arm automatically detects coke cans and collects them in a bag.
Performance of LDPC coded spread OFDM with clipping (2005)

We present the performance of OFDM systems with coding, spreading, and clipping. Low-Density Parity-Check (LDPC) codes give coding gains and spreading by the Walsh Hadamard transform gives gains in terms of increased frequency diversity as well as reduced peak-toaverage power ratio (PAPR) of the transmitted OFDM signal. By evaluating both the IFFT transform (OFDM) and the Walsh Hadamard transform in a single step, the number of operations needed for the spread OFDM system is actually less than for the conventional OFDM system. Reducing than for the conventional OFDM system. Reducing the PAPR is important in systems with clipping since it is related to the probability of clips. Each clip introduces clipping noise to the system which reduces the performance. Results of a clipped OFDM system with LDPC coding and spreading for an ETSI indoor wireless channel model are presented and compared with other systems. It is shown that there is a gain by spreading for LDPC coded OFDM systems, and especially for systems with clipping.
Polarization-independent depolarizers for highly coherent light using Faraday rotator mirrors (1997)

We propose two novel polarization-independent optical depolarizers for highly coherent light using Faraday rotator mirrors (FRM). One uses delay fibers, and the other uses frequency shifters for depolarization. We demonstrate experimentally their polarization-independent depolarization. We also discuss the factors degrading the performance of these depolarizers.
Altered somatic hypermutation patterns in COVID-19 patients classifies disease severity (2022)

Abstract The success of the human body in fighting SARS-CoV-2 infection relies on lymphocytes and their antigen receptors. Identifying and characterizing clinically relevant receptors is of utmost importance. We report here the application of a machine learning approach, utilizing B cell receptor repertoire sequencing data from severely and mildly infected individuals with SARS-CoV-2 compared with uninfected controls. In contrast to previous studies, our approach successfully stratifies non-infected from infected individuals, as well as disease level of severity. The features that drive this classification are based on somatic hypermutation patterns, and point to alterations in the somatic hypermutation process in COVID-19 patients. These features may be used to build and adapt therapeutic strategies to COVID-19, in particular to quantitatively assess potential diagnostic and therapeutic antibodies. These results constitute a proof of concept for future epidemiological challenges.
Immunoglobulin-dependent helper T cells: studies in the MOPC-315 system suggest a novel surface antigen phenotype. (1986)

We have previously provided evidence that the SRBC-immune helper T (TH) cells which enhance MOPC-315 plasmacytoma cell secretory differentiation in vivo (THd cells) differ in specificity, accessory cell requirements, and Qa-1 expression from the SRBC-immune TH cells which enhance MOPC-315 cell growth in vivo (THg cells). Indeed, like other immunoglobulin-dependent TH cells, THd cells in the 315 system do not develop in anti-IgM-treated, B cell-deficient mice, whereas THg cell development is unaffected. In this report, we provide evidence for other differences in the expression of surface antigens by these two TH cell populations. We find that, like most Lyt-1+, 2- T cells, the THg cells can be eliminated by monoclonal anti-L3T4 antibody and complement treatment, whereas such treatment had no effect on adoptive transfer of SRBC-immune THd cell activity. Similarly, THg cell activity was eliminated from SRBC-immune T cells by treatment with monoclonal anti-T cell receptor beta-chain allotope antibody plus anti-rat IgG and complement, whereas THd cell activity remained intact. Both helper cell activities were deleted by either anti-Lyt-1.2 or anti-Thy-1.2 antibody and complement treatment. Interestingly, the THd cell activity was abrogated by treating SRBC-immune T cells with monoclonal anti-B220 or monoclonal anti-p50 antibodies (RA3-3A1/6.1 and RA3-2C2/1, respectively) and complement, whereas THg cell activity was unaffected. Additional controls indicated that the THd effects did not arise by virtue of a two-cell interaction between a Thy-1+, B220- cell and a Thy-1-, B220+ cell, and it is therefore proposed that the THd effect arises from a single population of cells that exhibit a unique phenotype (Thy-1+, Ly-1+, 2-, L3T4-, B220+). The proposal is further supported by studies conducted with a T cell clone which promotes MOPC-315 cell secretory differentiation in vitro and which exhibits this surface antigen phenotype. The serologic differences between these two TH cell populations stress even further the likelihood that B cell growth and differentiation enhancement are mediated by distinct T cell subsets in this system, and raise the possibility that immunoglobulin-dependent TH cells in other systems will routinely exhibit a unique surface antigen profile. These data also imply that immunoglobulin-dependent TH cells (such as the THd cells) may not express antigen receptors that are identical to those expressed by MHC-restricted helper cells (such as our THg cells).
Band Structure of Quasi-1-Dimensional Polycondensed π-Systems, 4<sup>A)</sup>Energy Spectra of a Class of 1-D Ladder Type Polymers (1996)

Abstract The energy spectra of a class of 1-D ladder type polymers with a large number of π-centers in the elementary unit are investigated theoretically. the width of the energy gap, δ, is determined only by the topology and the geometry of the system: the elementary unit and the edge set connecting a pair of neighbouring elementary units. an extended Su-Schrieffer-Heeger approach including the π-π electron interaction on the Hartree-Fock-PPP level is employed for the investigation of the geometries- the bond lengths distortion of infinite polymers. It is shown that the electron-vibronic coupling leads to a marked poly(para-phenylene) substructure in the elementary unit. Polymers with more than 48 π-centers within the elementary unit are semiconductors with an energy gap, δ < 1 eV, which decreases monotonically to zero when the number of π centers increase.

Motion parameter estimation of a radiating point source with multiple tonals using acoustic Doppler analysis (2013)

The sound emitted by distant moving sources, such as air crafts, submarines and ships contain time-varying Doppler-shifted tonals when observed from a stationary sensor. This temporal variation in the Doppler shift of the tonal can be used for the estimation of time of closest approach, distance between the source and the sensor at the closest approach instant, the relative speed of the source and the rest frequency of the emitted tonal. The existing methods model the radiating source as a point source under uniform linear motion, and estimate the frequency of a single dominant tonal as it undergoes Doppler shift due to the relative motion of the source as compared to a stationary sensor. However, the received signal may consist of multiple tonals and their harmonics. In this case, the tonals exhibit dissimilar Doppler shifts as the Doppler shift depends on the rest frequency of the tonal. In this paper we consider the motion parameter estimation of a point source when the received signal is composed of multiple Doppler-shifted tonals, which may or may not be harmonically related. The frequencies corresponding to the multiple Doppler-shifted tonals present in the received signal are estimated over short intervals. We propose the use of the average of the estimated Doppler-shifted tonals for the estimation of the motion parameters. The average of the estimated frequencies preserves the temporal variation in the Doppler shift and hence it can be used for the estimation of the motion parameters. Once the motion parameters are estimated, it is also possible to extract the line spectrum, which is often used in applications such as the classification of the moving source. Simulations are used to demonstrate the efficacy of proposed algorithm, which utilizes the Doppler variation corresponding to multiple tonals as compared with the monotone case. The performance of the proposed algorithm in the presence of noise is assessed under several signal-to-noise ratios. The proposed algorithm is applied to actual pass-by sound of an aircraft and an underwater signal recorded for a ship.
Selection of Crabapple Pollinizers for ‘Fuji’ and‘Tsugaru’ Apple (2009)

Crabapple cultivars and Malusspecies were examined as pollinizers for two major apple cultivars in Japan: ‘Fuji’ and ‘Tsugaru’. Data on flowering dates, flowering intensity, and cross-compatibility were collected on 19 crabapple cultivars over several years. The following cultivars were selected as potential pollinizers for ‘Fuji’ and ‘Tsugaru’: M. Baccata79091 and ‘Sentinel’ for early bloom; M.× atrosanguinea20004522, ‘Red Bud’, and ‘Snowdrift’ for mid-bloom. All cultivars selected had white flowers with single petals. M. baccata79091 and ‘Sentinel’ bloomed about 2 to 3 days earlier than ‘Fuji’ and ‘Tsugaru’. Bloom time of terminal buds of M.× atrosanguinea20004522, ‘Red Bud’, and ‘Snowdrift’ was similar to ‘Fuji’ and ‘Tsugaru’. All selected crabapple cultivars had high bloom density. The percentage of fruit set for all cross combinations between crabapples and commercial cultivars was high. ‘Sentinel’ coincided with the bloom period of ‘Fuji’ and ‘Tsugaru’. However, ‘Sentinel’ tended produce fewer seeds per fruit in cross combination with ‘Fuji’. The other crabapples that we selected did not overlap with the entire bloom period of ‘Fuji’ and ‘Tsugaru’. Therefore, both an early-blooming pollinizer and a mid-blooming pollinizer should be planted in the sameorchards.
Holmium: YAG Laser Thermokeratoplasty for Hyperopia (1994)

Holmium:YAG laser thermokeratoplasty (LTK), a procedure using a solid-state infrared laser to treat hyperopia, was performed on 10 patients in phase I and 16 patients in phase II--in a total of 29 eyes at the Hunkeler Eye Clinic. Phase II was redesigned after phase I results showed undercorrection and regression. The follow-up period ranged from 1 to 24 months (mean 10.9 months). A total of 79% of phase II patients were within +/- 1.00 D of intended correction at the 6-month visit. Looking at both phases together, no patients had J2 or better near vision preoperatively, but 75% had J2 or better at the 6-month visit. A total of 43% of eyes in phase II lost 1 line and 7% lost two lines of best spectacle corrected visual acuity due to induction of irregular astigmatism. The surgical challenges are to insure appropriate centration of the procedure about the optical axis. Concerns about regression and stability will be defined as these patients are followed through their 2-year visits.
Recognizing Fall Actions from Videos Using Reconstruction Error of Variational Autoencoder (2019)

In this paper, we propose a method for detecting fall actions using a variational auto-encoder (VAE) with 3D-convolutional residual blocks. The VAE learns a distribution of Activity of Daily Life (ADL) data, and the reconstruction error is used to detect fall actions. The proposed method is a kind of unsupervised learning method with weakly labeled data for solving the problem of imbalance between the amount of fall data and that of ADL data. Furthermore, we propose extracting a human region from an entire image using skeleton information and aligning motions using the same joint point so that the neural network can focus on learning human motions, which can enhance the accuracy of fall detection. The results of experiments showed that our method achieved a competitive level of accuracy and better generalization ability compared to supervised learning with well-labeled data.
