Expression of Histamine H1‐Receptors in Xenopus Oocytes Injected with Messenger Ribonucleic Acid from Bovine Adrenal Medulla: Pertussis Toxin Insensitive Activation of Membrane Chloride Currents (1990)

Abstract Histamine H(2)-receptors have been identified in Xenopus oocytes previously microinjected with poly(A) + ribonucleic acid from bovine adrenal glands. Bath application of histamine to ribonucleic acid-primed oocytes evoked concentration-dependent, oscillating membrane currents under voltage-clamp conditions. H(1)-receptor specific antagonists clemastine, doxepin, pyrilamine, promethacine, diphenylhydramine, dephenylpyraline and chlorpheniramine, but not H(2)-receptor antagonists, cimetidine and ranitidine, inhibited histamine-induced responses. Membrane currents evoked by bath-applied histamine were insensitive to pertussis toxin, carried by chloride ions and dependent on intracellular but not extracellular calcium.
Self-Adhesive Ionomers for Alkaline Electrolysis: Optimized Hydrogen Evolution Electrode (2022)

Hydrogen produced through low-temperature water electrolysis using anion exchange membranes (AEM) combines the benefits of liquid-electrolyte alkaline electrolysis and solid-polymer proton exchange membrane electrolysis. The anion conductive ionomers in the oxygen-producing anode and hydrogen-producing cathode are a critical part of the three-dimensional electrodes. The ionomer in the hydrogen-producing cathode facilitates hydroxide ion conduction from the cathode catalyst to the anode catalyst, and water transport from the anode to the cathode catalyst through the AEM. This ionomer also binds the catalyst particles to the porous transport layer. In this study, the cathode durability was improved by use of a self-adhesive cathode ionomer to chemically bond the cathode catalyst particles to the porous transport layer. It was found that the cathode ionomers with high ion exchange capacity (IEC) were more effective than low IEC ionomers because of the need to transport water to the cathode catalyst and transport hydroxide away from the cathode. The cathode durability was improved by using ionomers which were soluble in the spray-coated cathode ink. Optimization of the catalyst and ionomer content within the cathode led to electrolysis cells which were both mechanically durable and operated at low voltage.
Multiple order coded aperture spectrometer (2007)

We introduce a multiple order coded aperture (MOCA) spectrometer. The MOCA is a system that uses a multiplex hologram and a coded aperture to increase the spectral range and throughput of the system over conventional spectrometers while maintaining spectral resolution. This results in an order of magnitude reduction in system volume with no loss in resolution.
Enhancement of RecET-mediated in vivo linear DNA assembly by a xonA mutation (2022)

Abstract Assembly of intact, replicating plasmids from linear DNA fragments introduced into bacterial cells, i.e. in vivo cloning, is a facile genetic engineering technology that avoids many of the problems associated with standard in vitro cloning. Here we report characterization of various parameters of in vivo linear DNA assembly mediated by either the RecET recombination system or the bacteriophage λ Red recombination system. As previously observed, RecET is superior to Red for this reaction when the terminal homology is 50 bases. Deletion of the E. coli xonA gene, encoding Exonuclease I, a 3’→5’ single-strand DNA exonuclease, substantially improves the efficiency of in vivo linear DNA assembly for both systems. Deletion of ExoI function allowed robust RecET assembly of six DNA segments to create a functional plasmid. The linear DNAs are joined accurately with very few errors. This discovery provides a significant improvement to previously reported in vivo linear DNA assembly technologies.

Measuring bone stiffness using spherical indentation (2018)

Spherical-tip indentation was found to be a repeatable test for measuring the elastic modulus of human cortical bone, demonstrated by a low co-efficient of repeatability in this study. It could not, however, reliably predict cortical bone elastic modulus determined by platens compression testing in this study. This may be due to indentation only probing mechanical properties at the micro-scale while platens compression testing assesses millimetre length-scale properties. Improvements to the testing technique, including the use of a larger diameter spherical indenter tip, may improve the measurement of bone stiffness at the millimetre scale and should be investigated further.
In vivo characterization of fatty acids in human adipose tissue using natural abundance 1H decoupled 13C MRS at 1.5 T: clinical applications to dietary therapy (2003)

Natural abundance proton-decoupled (13)C magnetic resonance spectroscopy was used to establish the in vivo lipid composition of normal adipose tissue and the corresponding effects of altered lipid diets. Experiments were performed on a standard 1.5 T clinical MR scanner using a double-tuned (1)H-(13)C coil. Peaks from double-bonded and methylene carbons were analyzed. Normal lipid composition was established in 20 control subjects. For comparison, five subjects on altered lipid diets were studied. Four subjects were on a fish oil supplement diet or predominantly seafood diet (polyunsaturated fatty acids), and one subject was on a Lorenzo's oil diet (monounsaturated fatty acids). Well-resolved (13)C spectra were obtained from the calf adipose tissue with a total acquisition time of 10 min. Model oil solutions were used to identify specific (13)C resonances. Subjects on lipid diets showed significantly elevated levels of monounsaturated and polyunsaturated fatty acids for Lorenzo's and fish oil diets, respectively. We conclude that (13)C MR spectroscopy can readily detect changes in lipid composition due to medium- and long-term therapeutic lipid diets. Since the examination is rapid, robust and noninvasive, opportunities arise for large clinical trials of preventive or therapeutic diets to be performed with (13)C MRS on a clinical MR scanner.
Improved Technology for Navigation-Guided Orbital Surgery and Reconstruction (2017)

Introduction: There is an increasing interest in endoscopic orbital and transorbital skull base surgery. Navigation guidance is highly important in endoscopic surgery for pathway creation, target manipulation, and reconstruction of normal bone anatomy. A major challenge to orbital navigation is segmentation (partitioning an image into different tissues) of orbital structures such as the globe, optic nerve, and extraocular muscles. The imaging of these structures during navigation is currently suboptimal. In this project, we developed a novel technique of segmenting the orbital bone cavity and registering the bone to the deformed side using intensity based registration. In addition, the optic nerve and extraocular musculature are segmented and transformed using the obtained transformation. These critical structures are included in the surgical planning and intraoperative navigation. In addition, the model can be used to construct patient specific implants or preoperatively.

Influence of the extrusion process on the morphology and micromechanical behavior of polystyrene‐block‐(polystyrene‐co‐butadiene)‐block‐polystyrene star block copolymer/homopolystyrene blends (2007)

Abstract The influence of the extrusion process on the morphology and micromechanical behavior of an asymmetric polystyrene‐ block ‐(polystyrene‐ co ‐butadiene)‐ block ‐polystyrene (SBS) star block copolymer and its blends with general‐purpose homopolystyrene (hPS) was studied with films prepared with a single‐screw extruder. The techniques used were transmission electron microscopy and uniaxial tensile testing. Unlike the pure SBS block copolymer possessing a gyroid‐like morphology, whose deformation was found to be insensitive to the processing conditions, the mechanical properties of the blends strongly depended on the extrusion temperature as well as the apparent shear rate. The deformation micromechanism was primarily dictated by the blend morphology. The yielding and cavitation of the nanostructures were the principal deformation mechanism for the blends having a droplet‐like microphase‐separated morphology, whereas cavitation dominated for the blends containing macrophase‐separated layers of polystyrene. The mechanical properties of the blends were further examined with respect to the influence of the temperature and shear rate on the phase behavior of the blends. © 2007 Wiley Periodicals, Inc.

Aspects of OFDM-Based 3G LTE Terminal Implementation (2010)

3GPP standardized an evolved UTRAN (E-UTRAN) within the release 8 Long Term Evolution (LTE) project. Targets include higher spectral efficiency, lower latency, and higher peak data rate in comparison with previous 3GPP air interfaces. The E-UTRAN air interface is based on OFDMA and MIMO in downlink and on SCFDMA in uplink. Main challenges for a terminal implementation include an efficient realization of fast and precise synchronization, MIMO channel estimation and equalization, and a turbo decoder for data rates of up to 75 Mbps per spatial MIMO stream. In this study, the authors outline the current 3GPP LTE standard and highlight some implementation details of an LTE terminal. Efficient sample algorithms are presented for key components in the baseband signal processing including synchronization, cell search, channel estimation and equalization, and turbo channel decoder. Their performances, computational and memory requirements, and relevant implementation challenges are discussed.
Automatic Determination of Shoulder Joint Limits Using Quaternion Field Boundaries (2003)

To provide efficient tools for the capture and modeling of acceptable virtual human poses, we propose a method for constraining the underlying joint structures based on real life data. Current tools for delimiting valid postures often employ techniques that do not represent joint limits in an intuitively satisfying manner, and furthermore are seldom directly derived from experimental data. Here, we propose a semi-automatic scheme for determining ball-and-socket joint limits by actual measurement and we apply it to modeling the shoulder complex, which—along with the hip complex—can be approximated by a three-degree-of-freedom ball-and-socket joint. Our first step is to measure the joint motion range using optical motion capture. We next convert the recorded values to joint poses encoded using a coherent quaternion field representation of the joint orientation space. Finally, we obtain a closed, continuous implicit surface approximation for the quaternion orientation-space boundary whose interior represents the complete space of valid orientations, enabling us to project invalid postures to the closest valid ones.

New Developments in Kisspeptin, Neurokinin B and Dynorphin A Regulation of Gonadotropin-Releasing Hormone Pulsatile Secretion (2014)

corporating the mechanisms by which KNDy neuropeptides modulate the reproductive axis (see [1] and the cover of this issue). The second article, by Goodman et al. [2] , reviews the roles of kisspeptin, NKB and Dyn in GnRH pulse generation as gathered from a comprehensive series of excellent studies in sheep from their laboratory as well as from equally detailed and incisive experiments in goats [for a review, see 3 ], which led to the promulgation of a model proposing a role for the KNDy neuron NKB in stimulating kisspeptin to initiate a GnRH pulse. NKB also stimulated Dyn release from KNDy neurons to inhibit their activity and terminate the GnRH pulse. Further studies using a range of agonists and antagonists of kisspeptin, NKB and Dyn led to the development of a modified model which invokes an action for kisspeptin in activating unidentified KNDy neurons which reinforce the stimulatory actions of NKB on KNDy neurons [see 2 , fig. 11]. The third article reviews the sexually dimorphic distribution of kisspeptin, NKB and Dyn in the male and female human brain and changes that occur with aging. Hrabovszky [4] points out that in various mammalian species, the majority of kisspeptin-synthesizing neurons are concentrated in two distinct cell populations in the The KNDy neuropeptides kisspeptin, neurokinin B (NKB) and dynorphin A (Dyn), play a pivotal role in regulating pulsatile gonadotropin-releasing hormone (GnRH) secretion. There are, however, relatively few studies attempting to integrate the interactions between KNDy-signalling systems. This special issue assembles three articles on this topic from studies on laboratory rats, sheep and humans. These reports go some way to clarifying kisspeptin, NKB and Dyn interactions in regulating pulsatile GnRH secretion and highlight species differences in the interplay and roles of these upstream regulators. In their article, Grachev et al. [1] point out that although the stimulatory effect of kisspeptin and the inhibitory effect of Dyn on the GnRH pulse generator are widely accepted, the effects of NKB in rodents are variable and sometimes controversial. Literature describing increased secretion of luteinizing hormone (LH) in response to NKB receptor agonism predominates and is in line with human physiology as well as with the pathophysiology of pubertal failure associated with disruption of NKB signalling. However, under hypoestrogenic conditions NKB exhibits a robust suppression of LH, which may shed light on the mechanisms of reproductive inhibition under pathological conditions such as anorexia nervosa.

Phase dynamics of coupled oscillators reconstructed from data (2008)

We systematically develop a technique for reconstructing the phase dynamics equations for coupled oscillators from data. For autonomous oscillators and for two interacting oscillators we demonstrate how phase estimates obtained from general scalar observables can be transformed to genuine phases. This allows us to obtain an invariant description of the phase dynamics in terms of the genuine, observable-independent phases. We discuss the importance of this transformation for characterization of strength and directionality of interaction from bivariate data. Moreover, we demonstrate that natural (autonomous) frequencies of oscillators can be recovered if several observations of coupled systems at different, yet unknown coupling strengths are available. We illustrate our method by several numerical examples and apply it to a human electrocardiogram and to a physical experiment with coupled metronomes.
An IMU-Driven Rider-on-Saddle Detection System for Electric-Power-Assisted Bicycles (2016)

This paper addresses the problem of motor activation on electric-power-assisted cycles that are not equipped with pedal torque sensors. The algorithm is based on inertial and motor velocity measurements along with pedal cadence. The problem is solved by a system that detects when the rider is on the saddle. Three different dynamics (longitudinal, lateral, and vertical) are analyzed, showing differences in their characteristics when the rider is on the saddle and when she is walking the bicycle. The problem is framed as a fault detection problem based on three independent analyses that are then fused. Experimental validation on a single-gear bicycle shows that the proposed solution outperforms the traditional cadence-based activation logic both reliability and reactiveness standpoints. The proposed system improves reactiveness compared with the standard cadence-based method without affecting safety.
