Dissipative motion of an electron-phonon system in a uniform electric field: An exact solution (1993)

Starting with Heisenberg's equations of motion, we have calculated the exact time-dependent drift velocity of a single electron that is harmonically coupled to a phonon bath according to the Caldeira-Leggett (CL) Hamiltonian and accelerated by a uniform electric field. Contrary to the conventional perturbational approach, the external field may be turned on abruptly at an arbitrary initial time; hence, the drift velocity reflects the genuine physical response to the electric field. The electron motion is shown to be irreversible if, for appropriate phonon-dispersion relations, the number of phonon modes approaches infinity. Although it has been devised for other purposes, the CL electron-phonon Hamiltonian, including the electric-field term, provides an exactly solvable transport model, highlighting interesting features of nonequilibrium thermodynamics, such as entropy production.
Improved system calibration for specular surface measurement by using reflections from a plane mirror (2016)

In this paper, we introduce a flexible and simple system calibration method for specular surface metrology based on the combination of reflection rays determined by the varied points on a screen and reflection images of a plane mirror without fiducials placed at three different locations. This calibration procedure involves three steps. The camera is first calibrated based on plane patterns. Then the reflection ray directions are measured via correspondence matching. The last calibration step is the pose estimation by the orthogonal iteration algorithm and reflections in a plane mirror. Basically, the concept of replacing the coordinates of the camera center with the reflection ray can alleviate the trouble of imaging aberration. Then global optimization can be operated with the orthogonal projection defined by the reflection ray, providing precise initial values for the process of bundle adjustment, compared to the classical calibration approach directly using the local optimization algorithm. Simulations and experiments both demonstrate the validity, efficiency, and robustness of the proposed improved method. In the simulations, the proposed method achieves the absolute errors of the camera parameters within 3 pixels and the relative errors of the screen pose are below 0.5% when the noise level is 0.6 pixel. Furthermore, the calibration method shows strong anti-noise ability, relying on the application of the reflection rays and the global optimization before the final bundle adjustment. In addition, the reconstruction accuracy in our experiment improves by 60.11% by the proposed method compared with the calibration procedure, which only utilizes the bundle adjustment optimization. In general, this novel calibration method can make the measurement achieve high accuracy and robustness at a low cost and with a simple setup, providing an efficient, economical, and flexible approach for a phase measuring deflectometry system in practical situations.
Probing the Degradation Mechanisms in Electrolyte Solutions for Li-Ion Batteries by in Situ Transmission Electron Microscopy (2014)

Development of novel electrolytes with increased electrochemical stability is critical for the next generation battery technologies. In situ electrochemical fluid cells provide the ability to rapidly and directly characterize electrode/electrolyte interfacial reactions under conditions directly relevant to the operation of practical batteries. In this paper, we have studied the breakdown of a range of inorganic/salt complexes relevant to state-of-the-art Li-ion battery systems by in situ (scanning) transmission electron microscopy ((S)TEM). In these experiments, the electron beam itself caused the localized electrochemical reaction that allowed us to observe electrolyte breakdown in real-time. The results of the in situ (S)TEM experiments matches with previous stability tests performed during battery operation and the breakdown products and mechanisms are also consistent with known mechanisms. This analysis indicates that in situ liquid stage (S)TEM observations could be used to directly test new electrolyte designs and identify a smaller library of candidate solutions deserving of more detailed characterization. A systematic study of electrolyte degradation is also a necessary first step for any future controlled in operando liquid (S)TEM experiments intent on visualizing working batteries at the nanoscale.

Infectious Bovine Mastitis Caused by Environmental Organisms (1998)

The purpose of this study was to determine the prevalence of environmental mastitis in dairy herds and identify the main environmental pathogens, and to evaluate the influence of season, housing and management. A total of 20,310 quarters of 5216 animals from 52 dairy herds in 32 counties was examined. Milk samples were aseptically collected for laboratory examination from mammary glands testing positive to any of the field tests. From these, 736 environmental infections were identified. The most frequently isolated environmental pathogens were algae of the genus Prototheca sp. (41.2%), Streptococcus uberis (21.1%), fungi (19.5%), enterobacteriacea (8.3%) and Nocardia sp. (6.6%). The occurrence of mastitis was not influenced by the herd size, use of dry cow therapy, or post milking teat dipping. A tendency for increased occurrence of environmental mastitis during the months of September to February (hot and wet weather) was observed, suggesting a seasonal influence.
Coagulating Colubrids: Evolutionary, Pathophysiological and Biodiscovery Implications of Venom Variations between Boomslang (Dispholidus typus) and Twig Snake (Thelotornis mossambicanus) (2017)

Venoms can deleteriously affect any physiological system reachable by the bloodstream, including directly interfering with the coagulation cascade. Such coagulopathic toxins may be anticoagulants or procoagulants. Snake venoms are unique in their use of procoagulant toxins for predatory purposes. The boomslang (<i>Dispholidus typus</i>) and the twig snakes (<i>Thelotornis</i> species) are iconic African snakes belonging to the family Colubridae. Both species produce strikingly similar lethal procoagulant pathologies. Despite these similarities, antivenom is only produced for treating bites by <i>D. typus</i>, and the mechanisms of action of both venoms have been understudied. In this study, we investigated the venom of <i>D. typus</i> and <i>T. mossambicanus</i> utilising a range of proteomic and bioactivity approaches, including determining the procoagulant properties of both venoms in relation to the human coagulation pathways. In doing so, we developed a novel procoagulant assay, utilising a Stago STA-R Max analyser, to accurately detect real time clotting in plasma at varying concentrations of venom. This approach was used to assess the clotting capabilities of the two venoms both with and without calcium and phospholipid co-factors. We found that <i>T. mossambicanus</i> produced a significantly stronger coagulation response compared to <i>D. typus</i>. Functional enzyme assays showed that <i>T. mossambicanus</i> also exhibited a higher metalloprotease and phospholipase activity but had a much lower serine protease activity relative to <i>D. typus</i> venom. The neutralising capability of the available boomslang antivenom was also investigated on both species, with it being 11.3 times more effective upon <i>D. typus</i> venom than <i>T. mossambicanus</i>. In addition to being a faster clotting venom, <i>T. mossambicanus</i> was revealed to be a much more complex venom composition than <i>D. typus</i>. This is consistent with patterns seen for other snakes with venom complexity linked to dietary complexity. Consistent with the external morphological differences in head shape between the two species, CT and MRI analyses revealed significant internal structural differences in skull architecture and venom gland anatomy. This study increases our understanding of not only the biodiscovery potential of these medically important species but also increases our knowledge of the pathological relationship between venom and the human coagulation cascade.

Bangs, Clicks, Snaps, Thuds and Whacks: An Architecture for Acoustic Transient Processing (1996)

We propose a neuromorphic architecture for real-time processing of acoustic transients in analog VLSI. We show how judicious normalization of a time-frequency signal allows an elegant and robust implementation of a correlation algorithm. The algorithm uses binary multiplexing instead of analog-analog multiplication. This removes the need for analog storage and analog-multiplication. Simulations show that the resulting algorithm has the same out-of-sample classification performance (∼93% correct) as a baseline template-matching algorithm.
Dynamic Characteristics of TEHD Tilt Pad Journal Bearing Simulation Including Multiple Mode Pad Flexibility Model (1993)

Abstract An approach for incorporating the heat transfer and elastic deformation effects into dynamic coefficient calculation is presented. A global analysis method is used, which finds the equilibrium pad tilt angles at each eccentricity position and includes cross-film variable viscosity, heat transfer effects in the lubricant, elastic deformation, heat conduction effects in the pads, and elastic deformation effect in the pivots. Deflection modes are used to approximate deformation of the top surface of the pads. The dynamic coefficients of a single pad are calculated at the equilibrium state of the bearing, based on numerical perturbation with respect to the bearing degrees of freedom. These include journal position, pad rotation, pivot deformation, and modal coordinates. The stiffness and damping coefficients are calculated and show very good agreement with experimental and numerical results from the existing literature.
Structure of the Yeast Vacuolar ATPase (2008)

The subunit architecture of the yeast vacuolar ATPase (V-ATPase) was analyzed by single particle transmission electron microscopy and electrospray ionization (ESI) tandem mass spectrometry. A three-dimensional model of the intact V-ATPase was calculated from two-dimensional projections of the complex at a resolution of 25 angstroms. Images of yeast V-ATPase decorated with monoclonal antibodies against subunits A, E, and G position subunit A within the pseudo-hexagonal arrangement in the V1, the N terminus of subunit G in the V1-V0 interface, and the C terminus of subunit E at the top of the V1 domain. ESI tandem mass spectrometry of yeast V1-ATPase showed that subunits E and G are most easily lost in collision-induced dissociation, consistent with a peripheral location of the subunits. An atomic model of the yeast V-ATPase was generated by fitting of the available x-ray crystal structures into the electron microscopy-derived electron density map. The resulting atomic model of the yeast vacuolar ATPase serves as a framework to help understand the role the peripheral stalk subunits are playing in the regulation of the ATP hydrolysis driven proton pumping activity of the vacuolar ATPase.
Interpretable ECG classification via a query-based latent space\n traversal (qLST) (2021)

Electrocardiography (ECG) is an effective and non-invasive diagnostic tool\nthat measures the electrical activity of the heart. Interpretation of ECG\nsignals to detect various abnormalities is a challenging task that requires\nexpertise. Recently, the use of deep neural networks for ECG classification to\naid medical practitioners has become popular, but their black box nature\nhampers clinical implementation. Several saliency-based interpretability\ntechniques have been proposed, but they only indicate the location of important\nfeatures and not the actual features. We present a novel interpretability\ntechnique called qLST, a query-based latent space traversal technique that is\nable to provide explanations for any ECG classification model. With qLST, we\ntrain a neural network that learns to traverse in the latent space of a\nvariational autoencoder trained on a large university hospital dataset with\nover 800,000 ECGs annotated for 28 diseases. We demonstrate through experiments\nthat we can explain different black box classifiers by generating ECGs through\nthese traversals.\n
Resistance in pepper plants induced by Fusarium oxysporum f. sp. lycopersici involves different defence‐related genes (2008)

Inoculation with Fusarium oxysporum f. sp. lycopersici (FOL) protects pepper plants from subsequent infection with Phytophthora capsici. In the present paper, the level of local and systemic protection achieved by plants induced with FOL was evaluated by quantifying the pathogen biomass and using real-time PCR. Differences in the amount of pathogen were found in stems and roots between FOL-treated and untreated plants, while pathogen biomass could not be detected in leaves of induced plants. Five defence-related genes coding for a PR-1 protein, a beta-1,3-glucanase, a chitinase, a peroxidase and a sesquiterpene cyclase were up-regulated 48 h after treatment in all the tissues studied, and maximal mRNAs levels were found in leaves.
Comments on "A small-signal MOSFET model for radio frequency IC applications" (1998)

For original paper see E. Abou-Allam and T. Manku, ibid., vol.16, pp.437-47 (1997). A comparison is provided between the recent small-signal analysis for the distributed gate resistance in MOSFET's at RF frequencies and the lumped-element model of an earlier publication for various CMOS technologies. An improved lumped-element model is also proposed. It is demonstrated that simplified lumped-element circuits are adequate for modeling the effect of distributed gate resistance on both the y parameters and the thermal noise.
Alveolar Epithelial Cell–Derived Mediators: Potential Direct Regulators of Large Airway and Vascular Responses (2017)

Bronchial epithelial cells and pulmonary endothelial cells are thought to be the primary modulators of conducting airways and vessels, respectively. However, histological examination of both mouse and human lung tissue reveals that alveolar epithelial cells (AECs) line the adventitia of large airways and vessels and thus are also in a position to directly regulate these structures. The primary purpose of this perspective is to highlight the fact that AECs coat the adventitial surface of every vessel and airway in the lung parenchyma. This localization is ideal for transmitting signals that can contribute to physiologic and pathologic responses in vessels and airways. A few examples of mediators produced by AECs that may contribute to vascular and airway responses are provided to illustrate some of the potential effects that AECs may modulate.
Application of Ozone from Sterilamp in Control of Mold, Bacteria, and Odors (1959)

In using a Sterilamp for the tenderization and preservation of meat and the preservation of other types of foods, a controlled amount of ozone is generated by the lamp to destroy or suppress growth of mold and bacteria in the unirradiated areas. Minute amounts of ozone are also used to destroy odors in both commercial and domestic refrigerators and in air-conditioning systems.
Home Use of Day-and-Night Hybrid Closed-Loop Insulin Delivery in Suboptimally Controlled Adolescents With Type 1 Diabetes: A 3-Week, Free-Living, Randomized Crossover Trial (2016)

Free-living home use of day-and-night closed-loop in suboptimally controlled adolescents with type 1 diabetes is safe, feasible, and improves glucose control without increasing the risk of hypoglycemia. Larger and longer studies are warranted.
Genome-wide transcriptional profiling linked to social class in asthma (2008)

This study provides the first evidence in a sample of paediatric patients diagnosed with asthma that the larger social environment can affect processes at the genomic level. Specifically, gene transcription control pathways that regulate inflammation and catecholamine signalling were found to vary by SES in children with asthma. Because these pathways are the primary targets of many asthma medications, these findings suggest that the larger social environment may alter molecular mechanisms that have implications for the efficacy of asthma therapeutics.
Phosphoenolpyruvate carboxylase inCorynebacterium glutamicumis dispensable for growth and lysine production (1993)

Phosphoenolpyruvate (PEP) carboxylase is assumed to be of major importance as anaplerotic enzyme in the amino acid producing Corynebacterium glutamicum. We constructed PEP carboxylase-negative strains of the wild-type and of the L-lysine producer MH20–22B by disruption of the respective gene. Analysis of these strains and comparison to the parental strains revealed: (i) identical growth characteristics on all media tested; (ii) identical capacity for lysine production; and (iii) the presence of the alternative anaplerotic enzyme PEP carboxykinase in all four strains. These results show that PEP carboxylase is dispensable as anaplerotic enzyme in C. glutamicum and may indicate that PEP carboxykinase alone can fulfil the anaplerotic function required for growth on glucose and for lysine production.
The HPLC Fingerprint Analysis of SelectedCirsiumSpecies with Aid of Chemometrics (2016)

Twelve Cirsium sp. methanolic extracts were analyzed using high-performance liquid chromatography gradient elution method with run time of 45 min. Four Kinetex (150 4.6 mm) chromatographic columns (C18 5 m, C18 2.6 m, pentafluorophenyl 5 m, phenyl-hexyl 5 m) and mobile phase consisting of methanol/water/formic acid 1% were used. Eight standards (naringin, vanilic acid, chlorogenic acid, caffeic acid, rutin, luteolin, apigenin, p-coumaric acid) were analyzed in the same conditions to confirm their presence in all of Cirsium methanolic extracts. The obtained chromatograms were compared and the similarity between them was evaluated using the similarity indices (Pearson's correlation coefficient, determination coefficient and congruence coefficient), distance indices (Euclidean, Manhattan and Chebyshev distance) and multi-scale structural similarity (MS-SSIM). Obtained results were confirmed using the principal component analysis (PCA). The attempt of identification of two unknown Cirsium species was performed using the similarity, distance indices and PCA analysis.
Secondary task workload test bench: 2TB (2014)

The scope of the project was to develop a simulator-based test method for assessing the load imposed on the driver from secondary tasks (in-vehicle equipment), i.e. to investigate commonly used performance indicators for their sensitivity to different levels of difficulty of secondary tasks loading on different modalities, and to evaluate their robustness across platforms.
Interaction of Electromagnetic Radiation with Organic Matrix Composites (1984)

A model was developed which describes the interaction between linearly polarized transverse electromagnetic waves or isotropic electromagnetic waves and continuous fiber-reinforced organic matrix composites. On the basis of the model, a user-friendly computer code was developed which provides the reflectance, transmittance, total ab sorbed energy, and absorbed energy distribution inside the composite. In order to validate the model, tests were performed using a waveguide measuring the reflectances and transmittances of Fiberite S2/9134B glass epoxy and Hercules AS/3501-6 graphite epoxy composites. The data were compared with the results calculated by the computer code. Good agreements were found between the experimental data and the numerical results. A parametric study was also performed which shows the dependence of the reflectance, transmittance, and absorbed energy on the characteristics of the incident electromagnetic wave, the geometry (composite and coating thicknesses and ply orientation), and the properties of the composite.
Strong Electrostatic Adsorption of Metals onto Catalyst Supports (2016)

Among the simplest, least expensive, and most prevalent methods to prepare supported metal catalysts begins with the process known as impregnation, whereby a
high surface area oxide or carbon support is contacted with a liquid solution containing dissolved metal ions or coordination complexes such as platinum hexachloride [PtCl6]–2 (derived from chloroplatinic acid, CPA), or platinum tetraammine
[(NH3)4Pt]+2 (PTA). After impregnation, wet slurries of support and metal precursor
are dried and then heated in various oxidizing or reducing environments in order to
remove the ligands and to reduce the metal to its active elemental state. This sequence
of steps in catalyst synthesis is illustrated in Figure 13.1.

The comparison of stepping responses following perturbations applied to pelvis during overground and treadmill walking (2017)

Based on these results we may conclude that stepping responses following perturbations can be studied on an instrumented treadmill where ground reaction forces can be readily assessed which is not the case during perturbed overground walking.
