Hidalgo Equivital(TM) Physiological Monitor Product Review and Data Summary (2008)

Abstract : Hidalgo Equivital(TM) Physiological Monitor and other sensors performance monitoring of physiological status was evaluated, and human data were collected on 12 wildland firefighters (WLFF). The devices were provided to the University of Montana Center for Work Physiology and Exercise Metabolism (WPEM) to collect data relative to energy costs and thermal strain. The Hidalgo system collected, recorded and displayed heart rate (HR), respiratory rate (RR), body position, core temperature (CT), and skin temperature (ST). CT was obtained using the VitalSense monitor with ingestible temperature pills. Other sensors were an ActiCal activity monitor and a Garmin Forerunner 301 GPS. Relative to other devices used by WPEM, the sensors performed well. Setup and data download was trouble-free, making field use of Hidalgo units practical and feasible. Data management performed well, but it was sometimes difficult to convert to other data formats. Some telemetry pills died or read too low. CT changes little despite fluctuations in RR and HR. Those data, collected from the Hidalgo system, appear reasonable for WLFF activities.
From indoor GIS maps to path planning for autonomous wheelchairs (2016)

This work focuses on how to compute trajectories for an autonomous wheelchair based on indoor GIS maps, in particular on IndoorGML maps, which set the standard in this context. Good wheelchair trajectories are safe and comfortable for the user and the people sharing the space with him, turn gently, are high legible, and smooth (at least G <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> continuos). We derive a navigation graph from a given IndoorGML map. We define and solve an optimization problem to find the desired path: given a succession of cells to traverse, the path corresponds to the best composite Bézier trajectory for the wheelchair. We discuss a related multi-objective path planning problem. Experimental results and an implementation on real robots show the planner performance.
PD-L1 Limits the Mucosal CD8+ T Cell Response to <i>Chlamydia trachomatis</i> (2013)

Chlamydia trachomatis infection is the most common bacterial sexually transmitted disease in the United States. Repeated infections with C. trachomatis lead to serious sequelae, such as infertility. It is unclear why the adaptive immune system, specifically the CD8(+) T cell response, is unable to protect against subsequent C. trachomatis infections. In this article, we characterize the mucosal CD8(+) T cell response to C. trachomatis in the murine genital tract. We demonstrate that the immunoinhibitory ligand, PD-L1, contributes to the defective CD8(+) T cell response. Deletion or inhibition of PD-L1 restores the CD8(+) T cell response and enhances C. trachomatis clearance.
A complex phenotype of peripheral neuropathy, myopathy, hoarseness, and hearing loss is linked to an autosomal dominant mutation in MYH14 (2011)

Both peripheral neuropathy and distal myopathy are well-established inherited neuromuscular disorders characterized by progressive weakness and atrophy of the distal limb muscles. A complex phenotype of peripheral neuropathy, myopathy, hoarseness, and hearing loss was diagnosed in a large autosomal dominant Korean family. A high density single nucleotide polymorphism (SNP)-based linkage study mapped the underlying gene to a region on chromosome 19q13.3. The maximum multipoint LOD score was 3.794. Sequencing of 34 positional candidate genes in the segregating haplotype revealed a novel c.2822G>T (p.Arg941Leu) mutation in the gene MYH14, which encodes the nonmuscle myosin heavy chain 14. Clinically we observed a sequential pattern of the onset of muscle weakness starting from the anterior to the posterior leg muscle compartments followed by involvement of intrinsic hand and proximal muscles. The hearing loss and hoarseness followed the onset of distal muscle weakness. Histopathologic and electrodiagnostic studies revealed both chronic neuropathic and myopathic features in the affected patients. Although mutations in MYH14 have been shown to cause nonsyndromic autosomal dominant hearing loss (DFNA4), the peripheral neuropathy, myopathy, and hoarseness have not been associated with MYH14. Therefore, we suggest that the identified mutation in MYH14 significantly expands the phenotypic spectrum of this gene.

Method for Profiling Mucin Oligosaccharides from Gastric Biopsies of Rhesus Monkeys with and without <i>Helicobacter pylori</i> Infection (2007)

A method for in vivo analysis of gastric mucin oligosaccharides was developed and applied to rhesus monkeys with and without Helicobacter pylori infection. Mucin-type O-linked oligosaccharides were directly released by reductive beta-elimination from gastric biopsies from rhesus monkeys. The released oligosaccharides were structurally characterized by matrix-assisted laser desorption/ionozation and electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry. A diverse profile of neutral and acidic oligosaccharides was observed with these techniques. The most predominant core structure detected in all of the samples at relatively high abundance corresponded to core 2 (2HexNAc-1Hex, m/z = 611.227). The spectra generated from H. pylori-infected monkey samples showed fewer oligosaccharides collectively. Peaks corresponding to 1HexNAc-1Hex (m/z = 408.148) and 2HexNAc (m/z = 449.174), which most likely represent core structures, were absent in all infected monkeys studied, although present in all uninfected monkeys. Unsupervised cluster analysis demonstrated clear differences between the peaks detected in uninfected and naturally infected monkey samples. The results suggest that H. pylori infection is associated with lower relative abundance of oligosaccharides and loss of mucin-type core structures. This method can be applied to characterize the glycans associated with the mucin lining of live animals and allows for repeated analysis of the same animal over the course of infection.
Calibration of Laser Fluorescence Measurements of Lubricant Film Thickness in Engines (1988)

<div class="htmlview paragraph">A laser fluorescent diagnostic method was employed to measure lubricant film thickness on the cylinder wall/piston interface of two engines. The system output signal was calibrated using lubricant samples of known thickness, and by comparison of a known piston ring profile to measured lubricant film contours. Agreement of the results of the two calibration methods was within 5%. A relative calibration was performed with three oils having different additive packages, and with an oil contaminated through use in a commercially operated engine. The calibration coefficients for the oils, relating output voltage to film thickness, varied within a factor up to two, depending on lubricant type and age.</div> <div class="htmlview paragraph">The laser fluorescent apparatus was installed for use with a single cylinder test version of the Cummins VT-903 diesel engine. An optical passage was created through the block and cylinder wall using a quartz window. Preliminary results in the motored engine indicate a lubricant film thickness of approximately two microns, at the upper portion of the cylinder wall, on the minor-thrust face.</div>
Development of a new OFDM transceiver without guard interval (2007)

This paper develops a new orthogonal frequency division multiplexing (OFDM) receiver model that does not use the guard interval. This proposed technique (termed as preprocessing technique) is further extended to the IEEE 802.11a standard for wireless local area networks (WLANs) in this paper. The paper also addresses the other major OFDM receiver design issues, i.e., symbol detection, carrier frequency offset estimation, and channel estimation. The preamble approved by the IEEE 802.11a Standard is used to accomplish synchronization and estimation at the receiver. The paper compares the performance of the conventional OFDM system, which uses the guard interval with that of the newly proposed OFDM system that does not use the guard interval.
Simulation of Genetic Systems by Automatic Digital Computers VI. Epistasis (1960)

Simulation, by Monte Carlo methods, of the effect on the genotype of seleotion against phenotypic extremes has shown that selection will lead to fixation of a simple additive genetic system at an extremely slow rate in all but very small populations. In oomplex epistatio systems, such selection operates to modify the relation of the genotype to the phenotype. The relationship beoomes an S·shaped function. The efficienoy of seleotion is independent of population size. The deviation from initial gene frequencies due to selection is far less per unit decrease of phenotypio variability in the epistatic than in the additive lines.
Growth‐related variation of α<sub>2</sub>‐adrenergic receptivity in the HT 29 adenocarcinoma cell‐line from human colon (1985)

The human colon adenocarcinoma cell-line HT 29 has been shown to possess functional alpha 2-adrenergic receptors. Here, [3H] clonidine was used as radioligand to study the evolution of alpha 2-adrenergic receptivity during the time course of HT 29 cell culture. Scatchard analysis of the saturation curves indicates that the number of [3H]clonidine binding sites increases throughout the 17 day culture period. The maximal number of alpha 2-adrenoceptors is found during the stationary phase of growth, when cell density is high and mitotic rate low. Moreover, the use of adrenaline and clonidine as alpha 2-adrenergic agonists reveals a relationship between the number of receptors and the intensity of the biological effect associated with their stimulation (inhibition of the VIP-induced cyclic AMP accumulation).
Facile synthesis of reduced graphene oxide in supercritical alcohols and its lithium storage capacity (2011)

A facile and green method to produce reduced graphene oxide (RGO) nanosheets based on supercritical alcohols is described. The obtained RGO nanosheets exhibited a high carbon-to-oxygen ratio (up to 11.89, determined by X-ray photoelectron spectroscopy), high electronic conductivity (up to 10 600 S m−1), and high lithium storage capacity with good cyclability (652 mA h g−1 at a 50 mA g−1 after 40 cycles) when tested as an anode material.
Enhanced efficiency of internal combustion engines by employing spinning gas (2014)

The efficiency of the internal combustion engine might be enhanced by employing spinning gas. A gas spinning at near sonic velocities has an effectively higher heat capacity, which allows practical fuel cycles, which are far from the Carnot efficiency, to approach more closely the Carnot efficiency. A remarkable gain in fuel efficiency is shown to be theoretically possible for the Otto and Diesel cycles. The use of a flywheel, in principle, could produce even greater increases in efficiency.
Your AP knows how you move (2014)

Recent WiFi standards use Channel State Information (CSI) feedback for better MIMO and rate adaptation. CSI provides detailed information about current channel conditions for different subcarriers and spatial streams. In this paper, we show that CSI feedback from a client to the AP can be used to recognize different fine-grained motions of the client. We find that CSI can not only identify if the client is in motion or not, but also classify different types of motions. To this end, we propose APsense, a framework that uses CSI to estimate the sensor patterns of the client. It is observed that client's sensor (e.g. accelerometer) values are correlated to CSI values available at the AP. We show that using simple machine learning classifiers, APsense can classify different motions with accuracy as high as 90%.
A natural interface for multi-focal plane head mounted displays using 3D gaze (2014)

In mobile augmented reality (AR), it is important to develop interfaces for wearable displays that not only reduce distraction, but that can be used quickly and in a natural manner. In this paper, we propose a focal-plane based interaction approach with several advantages over traditional methods designed for head mounted displays (HMDs) with only one focal plane. Using a novel prototype that combines a monoscopic multi-focal plane HMD and eye tracker, we facilitate interaction with virtual elements such as text or buttons by measuring eye convergence on objects at different depths. This can prevent virtual information from being unnecessarily overlaid onto real world objects that are at a different range, but in the same line of sight. We then use our prototype in a series of experiments testing the feasibility of interaction. Despite only being presented with monocular depth cues, users have the ability to correctly select virtual icons in near, mid, and far planes in 98.6% of cases.
Regeneration of Periodontal Ligament for Apatite-coated Tooth-shaped Titanium Implants with and without Occlusion Using Rat Molar Model (2012)

Regeneration of periodontal ligament (PDL) is still a major issue in implant dentistry. In this study, we evaluated the effects of hydroxyapatite (HA) coating and occlusion on the regeneration of PDL around tooth-shaped titanium implants with root form. Three groups of tooth-shaped titanium implants, namely, non-HA-coated without occlusion (HA-/OCL-), HA-coated without occlusion (HA+/OCL-), and HA-coated with occlusion (HA+/OCL+), were immediately implanted into extracted tooth sockets with remaining PDL of rat molar model and the regeneration of PDL was examined histomorphometrically and histologically. Direct bony attachments were formed at the HA+/OCL- implant interface. In contrast, soft peri-implant tissue was distinctly seen between the HA+/OCL+ implant surface and surrounding alveolar bones. The shape of the load-time curve for the HA+/OCL+ group was similar to that for natural teeth. Peri-implant tissue of the HA+/OCL+ implants exhibited alkaline phosphatase with a distribution and activity similar to those of the PDL. Collagen fiber bundles were found functionally oriented in some regions of the peri-implant tissue. These findings indicate that the remaining PDL tissue around extracted sockets has the ability to regenerate bone and PDL-like tissues on HA-coated tooth-shaped implants. Occlusal loads to the HA-coated implants may induce regeneration of PDL-like tissue in the peri-implant tissue.
Ion‐Spray Mass Spectrometry of Lipopeptide Vaccines (1992)

Its speed and accuracy and the extremely simple sample preparation required recommends ion‐spray mass spectrometry as a technique for studying highly lipophilic and amphiphilic molecules of high molecular mass and, in particular, for biomolecules (which have not previously been able to be characterized by mass spectrometry). Routine analyses detect molecular masses up to 6000 u with an accuracy of ± 1 u.
A 19-43 GHz Linear Power Amplifier in 28nm Bulk CMOS for 5G Phased Array (2019)

This paper presents a linear power amplifier (PA) implemented in 28-nm bulk CMOS process for 5G communication systems with wideband operation in order to cover all possible 5G frequency bands in the United States, Europe, and Asia. The PA is designed using FET stacking technique that allows high output power for low breakdown CMOS devices. The PA has differential inputs and a wideband balun at the output to enable direct interface with single-ended antennas. The wideband balun design will be introduced. The single stage PA shows a measured gain of 10dB, 3 dB bandwidth (BW) from 19 to 43 GHz (77.5%) with 16dBm of maximum output power, 13.6dBm output P1dB at 24 GHz, output IM3 better than 30dBc up to 8dBm output power, and with a peak power added efficiency of 26% with a 2-volt supply.

Switch studies: a review (2002)

Many physicians and patients wish to switch from successful protease inhibitor (PI)-based regimens to alternative regimens, usually composed of a nonnucleoside reverse transcriptase inhibitor (NNRTI) or abacavir plus two nucleoside reverse transcriptase inhibitors (NRTIs). This reflects a desire to avoid or reverse the metabolic changes observed during long-term PI-based antiretroviral therapy; to alleviate PI-associated adverse effects; and to improve adherence by simplifying the regimen. Data from a number of randomized and cohort PI switch studies are reviewed. Overall, the results of these studies are mixed, perhaps because of limitations in study design, patient number and duration of follow-up. In most studies, the frequency of virological failure is reduced by switching to a NNRTI regimen. Switching to an abacavir-based regimen is associated with two-fold higher risk of virological failure if mutations in the reverse transcriptase gene pre-exist. Improvements in metabolic and lipid abnormalities have not been uniform but favourable lipid changes have been reported, particularly after switching to nevirapine. Resolution of lipodystrophy symptoms has not been demonstrated objectively, perhaps because of insufficient follow-up and/or the role of NRTIs in this syndrome.
Generation of Anti-Hirudin Antibodies in Heparin-Induced Thrombocytopenic Patients Treated With R-Hirudin (1999)

R-hirudin may be antigenic in patients with heparin-induced thrombocytopenia. More comprehensive investigations will be required to determine the biological relevance of this and to establish the antibody-generation pattern in other diseases.
An acoustic wave equation for orthorhombic anisotropy (2003)

Abstract Using a dispersion relation derived under the acoustic medium assumption, I obtain an acoustic wave equation for orthorhombic media. Although an acoustic wave equation does not strictly describe a wave in anisotropic media, it accurately describes the kinematics of P-waves. The orthorhombic acoustic wave equation, unlike the transversely isotropic one, is a sixth-order equation with three sets of complex conjugate solutions. Only one set of these solutions are perturbations of the familiar acoustic wavefield solution for isotropic media for incoming and outgoing P-waves and, thus, are of interest here. The other two sets of solutions are simply the result of this artificially derived sixth-order equation.
Passively Mode-Locked Nd:YLF and Nd:YAG Lasers using a New Intracavity Antiresonant Semiconductor Fabry-Perot (1992)

A new antiresonant Fabry-Perot saturable absorber (A- FPSA) is an intracavity, low-loss, compact (total thickness < 500 μm) nonlinear mirror which starts and sustains stable modelocking of Nd:YLF and Nd:YAG lasers and produces 3.3 ps and 9.2 ps pulse durations respectively. Using a Fabry-Perot at antiresonance transforms the semiconductor to a high saturation intensity, low-loss saturable absorber as required for modelocking solid-state lasers. In addition, we are able to passively Q-switch the Nd:YLF laser.
