Multi-wavelength imaging with extended depth of field using coded apertures and radial quartic phase functions (2023)

This study demonstrates a new multi-wavelength imaging technique with an extended depth of field. The spatial and spectral information of the objects is encoded into a single bipolar function of sparse dots using coded phase masks (CPMs) and a radial quartic phase function (RQPF). Each wavelength produces an intensity response of sparse dots with a unique set of distances between the dots, enabling the decoding of multispectral information. The RQPF is introduced to extend the depth of focus for different wavelengths. A library of point spread holograms (PSHs) is prerecorded with uniquely designed CPMs by placing the point objects of multiple wavelengths at the system input. For reconstruction, the object hologram is cross-correlated with a PSH corresponding to the wavelength of the object. The results are compared with direct imaging and with the conventional technique of interferenceless coded aperture correlation holography. The method is unique because the number of camera shots required for multi-wavelength imaging is the same as for monochromatic imaging.
Selektivitätserhöhung einer einfachen photosensitiven Sonde in Gegenwart großer Mengen Cholesterin (1994)

Auch “halbierte” Sondenmoleküle 1 können, wie ihre membrandurchspannenden Analoga, als Bestandteil von Phospholipidvesikeln mit sehr hoher Selektivität die Endpositionen der Phospholipidketten und des Cholesterins angreifen – vorausgesetzt, Cholesterin ist in großen, in der Zelle jedoch durchaus üblichen Anteilen (über 30 Mol‐%) zugegen. magnified image
Structure and Population of Complex Ionic Species in FeCl2 Aqueous Solution by X-ray Absorption Spectroscopy (2022)

Technologies for mass production require cheap and abundant materials such as ferrous chloride (FeCl<sub>2</sub>). The literature survey shows the lack of experimental studies to validate theoretical conclusions related to the population of ionic Fe-species in the aqueous FeCl<sub>2</sub> solution. Here, we present an in situ X-ray absorption study of the structure of the ionic species in the FeCl<sub>2</sub> aqueous solution at different concentrations (1-4 molL<sup>-1</sup>) and temperatures (25-80 °C). We found that at low temperature and low FeCl<sub>2</sub> concentration, the octahedral first coordination sphere around Fe is occupied by one Cl ion at a distance of 2.33 (±0.02) Å and five water molecules at a distance of 2.095 (±0.005) Å. The structure of the ionic complex gradually changes with an increase in temperature and/or concentration. The apical water molecule is substituted by a chlorine ion to yield a neutral Fe[Cl<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>]<sup>0</sup>. The observed substitutional mechanism is facilitated by the presence of the intramolecular hydrogen bonds as well as entropic reasons. The transition from the single charged Fe[Cl(H<sub>2</sub>O)<sub>5</sub>]<sup>+</sup> to the neutral Fe[Cl<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>]<sup>0</sup> causes a significant drop in the solution conductivity, which well correlates with the existing conductivity models.
Contact Mode Guided Sampling-Based Planning for Quasistatic Dexterous Manipulation in 2D (2020)

The discontinuities and multi-modality introduced by contacts make manipulation planning challenging. Many previous works avoid this problem by pre-designing a set of high-level motion primitives like grasping and pushing. However, such motion primitives are often not adequate to describe dexterous manipulation motions. In this work, we propose a method for dexterous manipulation planning at a more primitive level. The key idea is to use contact modes to guide the search in a sampling-based planning framework. Our method can automatically generate contact transitions and motion trajectories under the quasistatic assumption. In the experiments, this method sometimes generates motions that are often pre-designed as motion primitives, as well as dexterous motions that are more task-specific.
Emulsion Stabilized with Starch Octenyl Succinate Prolongs Nisin Activity Against Listeria Monocytogenes in a Cantaloupe Juice Model (2016)

Food safety related to fresh and fresh-cut produce, such as cantaloupe, is a great challenge in the food industry. Various processing technologies, including the use of antimicrobial materials, have been applied to reduce pathogens. Nisin, an antimicrobial peptide, shows strong inhibitory activity against Listeria monocytogenes (LM); however, it suffers from quick depletion in foods. In this study, the protective effect of starch octenyl succinate (starch-OS) stabilized emulsion on nisin was evaluated in a cantaloupe juice model. Results showed that the proteolytic enzyme in cantaloupe juice caused nisin depletion, and the adsorption of nisin in emulsion led to considerable protection of antimicrobial activity. After 1, 3, and 6 d of incorporation with cantaloupe juice, the size of LM inhibitory ring were 7.64, 7.60, and 2.97 mm, respectively for emulsion formulations, whereas it reduced from 3.60 mm to a negligible level for nisin-alone. This study showed the potential of using carbohydrate colloidal systems to prolong the efficacy of antimicrobial materials.
A survey of methods for the detection of thermal oxidation in high-density polyethylene pipes (1981)

Seven methods for the detection of thermal oxidation of the inner wall surface of high-density polyethylene (HDPE) pipes are presented. The methods presented include infrared spectroscopy, polarized light microscopy, differential scanning calorimetry, scanning electron microscopy, gloss measurements and uniaxial creep tests. These tests have been developed on the basis of earlier reported data for a large number of PE pipes. The tests are compared with each other and with the internal pressurizing test with respect to reliability of results, the time taken to determine whether or not a pipe is oxidized, the experimental difficulties, costs, etc.
Ultrasound Induced Synthesis of CdS Nanocrystals Under Continuous Flow (2013)

Cadmium sulfide nanoparticles generally exhibit quantum confinement effects when the particle size is less than 10 nm and approaches the Bohr exciton radius. It is a widely used buffer material in solar cells owing to its wide band transmission of solar light and hence used as a window layer in photovoltaic devices. Sonochemical synthesis permits the rapid heating of reactant baths by acoustic cavitation leading to high local temperatures. In this research, results from batch trials for heating and synthesis are reported. These results were used to design experiments for the continuous synthesis of CdS nanoparticles using a sonochemical reactor consisting of a flow cell and a high intensity horn. By utilizing the continuous synthesis approach a more than hundred fold reduction in processing time over batch synthesis for similar product was reported.
New Compressed Air Energy Storage Concept Improves the Profitability of Existing Simple Cycle, Combined Cycle, Wind Energy, and Landfill Gas Power Plants (2004)

The proposed novel compressed air energy storage (CAES) concept is based on the utilization of capacity reserves of combustion turbine (CT) and combined cycle (CC) plants for the peak power generation, instead of development of highly customized and expensive turbo-machinery trains. These power reserves are particularly high during high ambient temperatures that correspond to typical summer peak power requirements. The stored compressed air will be injected into the CT after the compressor diffuser to supplement the reduced (due to high ambient temperature or altitudes) mass flow, through the turbine to the full potential (typically achieved at low ambient temperatures). The alternative concept, with stored compressed air, is humidification before injection into the CT, this reduces the auxiliary compressor size, the storage volume and associated costs. Power increase of up to 25% can be realized, coincidental with that which is typical for a CAES plant, significant reduction in the heat rate and emissions. The novel CAES concept reduces specific plant costs by a factor of two, which makes it particularly effective for integration with renewable energy sources, like wind energy plants and landfill gas (LFG) plants. The paper also presents an alternative small capacity CAES plant, which is based on using smaller man-made storage facilities (high pressure pipes and/or vessels), either underground or above ground that can be readily constructed at CT sites without specific geological requirements. The latter part of this paper specifically concentrates on integration of CAES with wind and landfill gas (LFG) plants.
Impact of metal gate electrode on Weibull distribution of TDDB in HfSiON gate dielectrics (2009)

The slope parameter of Weibull plot of Tbd, beta, strongly depends on gate electrode material for metalgate/HfSiON gate stacks in n-FETs. Furthermore beta of Tbd under bipolar stress is larger than that under DC stress. From these results, it is found that the balance of injected carriers is strongly related to beta in terms of the origin of large beta for metal-gate/high-k.
Front Matter: Volume 10049 (2017)

The Molecular Guided Surgery III conference grew in attendance yet again in this third year, and the number of invited and contributed talks grew as well. This year the focus of the meeting shifted a bit more towards technology goals, standards, FDA approvals, and society guidance. As in previous years, the goal is to foster interaction of basic scientists, translational scientists, companies and practicing surgeons towards the purpose of molecular guided surgery. The presentations started with Advanced Molecular Imaging Methods, then Imaging Systems, then Contrast Agents, and then to Clinical Translation and Applications. The conference ended with an invited review talk from the FDA, and a discussion panel focused around devices, standards, calibration, and differences between academic clinical trials and company developed device performance. This year there was also an additional joint symposium with the Optical Methods for Tumor Treatment and Detection conference, on the Monday morning focused on the topic of Optical and Ionizing Radiation Interactions for Diagnosis and Therapy.
ChemInform Abstract: EIN NEUER WEG ZU 1‐ALKYLTHIO‐3,5‐DIHYDROXYBENZOLEN (MONOTHIOPHLOROGLUCIN‐S‐ALKYLAETHERN) (1975)

Abstract Die Umsetzung von Phloroglucin‐dimethyläther (I) mit Dimethylthiocarbamoylchlorid (II) und Natriumhydrid in Dimethylformamid bei 70°C führt zum O‐Ester (III), der unter Stickstoff in 90 Min. bei 265°C zum S‐Ester (IV) isomerisiert wird.
High-Linearity Bi-SQUID: Design Map (2018)

We consider conditions allowing attending the highly linear voltage response of a bi-SQUID, taking into consideration the inductances of both loops and their shared inductance. The existence of the small latter one allows improving the law of the flux to phase transformation and essential enlarging margins of the high-linearity response. The reported data represent the design map for creation practical high-performance bi-SQUID-devices, taking into account a restricted fidelity in both design and fabrication.
Structural and Microstructural Characterization of the Growth Lines and Prismatic Microarchitecture in Red Abalone Shell and the Microstructures of Abalone “Flat Pearls” (2002)

The structure of the growth lines in the shell of the red abalone, Haliotis rufescens, has been characterized by X-ray diffraction analysis and by scanning and transmission electron microscopy. The growth lines consist of a blocklike microstructure and a spherulitic microstructure, separated by a green organic matrix interlayer. The minerals in both the blocklike and spherulitic structures have been determined to be aragonite, the same CaCO3 polymorph as in the nacreous microstructure in these shells. The spherulitic structure is composed of radially distributed elongated crystals, whereas the blocklike structure involves crystalline aggregates with irregular shape. The individual aggregates are approximately single crystal, with orientations identical to that of the adjacent stack of tablets in the nacreous structure. The interfaces defining the transition from nacreous to blocklike microstructures are abrupt; on the other hand, the transition from spherulitic to nacreous microstructures shows more irregularity because of the occasional intergrowth of elongated crystals into the nacreous region. The microstructures of “flat pearls”, produced by mineralization of an abiotic substrate (a glass cover slip) inserted between the mantle tissue and the growing edge of the shell in a live abalone, have also been studied. A thin calcitic CaCO3 layer is produced on the center of the glass substrate, which is soon covered by green organic matrix. This matrix extends beyond the calcitic region; that is, it can be secreted directly onto the glass. Mineralization of this green matrix layer involves the deposition of spherulitic aragonite, similar to that occurring in the native shell, which is then capped by nacreous aragonite. Thus, the microstructures within the flat pearls mimic very closely certain aspects of the microstructures within the growth lines of the native shell.
Search for the rare decay $B^0 \to J/\psi\phi$ (2020)

A search for the rare decay B0 → J/ψφ is performed using pp collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 fb−1. No significant signal of the decay is observed and an upper limit of 1.1 × 10−7 at 90% confidence level is set on the branching fraction.
Increased incidence of isoproterenol-induced ventricular fibrillation in aging rats (1987)

Prolonged beta-adrenergic stimulation obtained by subcutaneous injection of isoproterenol in unanesthetized, unrestrained rats elicited ventricular fibrillation in approximately 80% of animals at 10-12 months of age. Ventricular fibrillation failed to occur in 1-month-old rats and involved only 12% of rats at 2 months. Senescence appeared not to increase the frequency of ventricular fibrillation since a similar incidence was seen in rats at 10-12 and 19-21 months. In all instances, ventricular fibrillation was preceded by ECG changes consistent with acute subendocardial ischemia. To evaluate whether acute beta-adrenergic stimulation elicits comparable cardiovascular effects in animals of different age, a dose-response curve to intravenous injection of isoproterenol was performed in anesthetized rats. Changes in heart rate, systemic arterial pressure, left ventricular pressure, and dP/dt were not different among animal groups. It was concluded that the arrhythmogenic potential of isoproterenol may not be related to differences in cardiac beta-receptor sensitivity with age as suggested by the comparable changes in the inotropic and chronotropic actions of isoproterenol in the animal groups studied.
Selective amplification of one allele and mutations of the EGFR gene in lung cancers (2005)

2789 Abstract Purpose : We examined the relationship between allele specific amplification of a polymorphic dinucleotide repeat (CA-SSR I) in intron one of the EGFR gene and mutations in its tyrosine kinase (TK) domain of the gene in Orientals and other ethnicities. Background : Mutations in the TK domain of EGFR occur in distinct subpopulations of lung cancers and have been reported to predict, imprecisely, for response to TK inhibitors (TKIs). Gene amplifcation has also been reported in similar subpopulations of lung cancers. Over expression of the gene is frequent in lung cancers but does not correspond to mutational status. Selective amplification of the shorter allele of the CA-SSRI polymorphic locus has been linked to over expression of EGFR in breast cancers. These findings suggest that factors other than mutation such as allele specific amplification of CA-SSR I may modulate the response to TKIs. Methods : We examined 517 resected lung cancers including 308 (60%) from Orientals and 209 (40%) from other ethnicities and corresponding non malignant lung tissues. We sequenced the four exons (18 - 21) of the TK domain known to harbor activating mutations. The status of the CA-SSR I alleles (presence of heterozygosity, repeat number of the alleles, and relative amplification of one allele) was determined by a standardized semiautomated method of microsatellite analysis. Results : In Orientals, the modal number of the two alleles was 20/20 compared to 16/20 for other ethnicities (p
Rasch validation of the German translation of the Prosthetic Limb Users Survey of Mobility short forms in people with lower limb amputation (2022)

Rasch analysis of the German translation of both PLUS-M short forms showed good psychometric qualities. In addition, our study showed that test scores from the PLUS-M-12 are more accurate. Therefore, the PLUS-M-12 is recommended for individual-level clinical applications (e.g., classification or change assessment).
Wireless Communication in Modular Multilevel Converters and Electromagnetic Interference Characterization (2022)

The wireless control of modular multilevel converter (MMC) submodules was recently proposed. The success of the control depends on specialized control methods suitable for wireless communication and a properly designed wireless communication network in the MMC valve hall while aiming for low latency and high reliability. The wireless communication in the hall can be affected by the electromagnetic interference (EMI) of MMC submodules, voltage and current transients. In this article, firstly, a wireless communication network based on 5G New Radio is designed for an example full-scale MMC valve hall. After that, the radiated EMI characteristics of the MMC submodules with different voltage and current ratings and two dc circuit breakers are measured. The effects of EMI on wireless communication in the multi-GHz frequency band are tested. The interference from the components is confined below <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\mathrm {500 \text {M} \text {Hz} }$ </tex-math></inline-formula> , and the wireless communication with <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\mathrm {5825 \text {M} \text {Hz} }$ </tex-math></inline-formula> center frequency is not affected by the interference.
Automating the layout of network diagrams with specified visual organization (1994)

Network diagrams are a familiar graphic form that can express many different kinds of information. The problem of automating network-diagram layout has therefore received much attention. Previous research on network-diagram layout has focused on the problem of aesthetically optimal layout, using such criteria as the number of link crossings, the sum of all link lengths, and total diagram area. In this paper the authors propose a restatement of the network-diagram layout problem in which layout-aesthetic concerns are subordinated to perceptual-organization concerns. The authors present a notation for describing the visual organization of a network diagram. This notation is used in reformulating the layout task as a constrained-optimization problem in which constraints are derived from a visual-organization specification and optimality criteria are derived from layout-aesthetic considerations. Two new heuristic algorithms are presented for this version of the layout problem: one algorithm uses a rule-based strategy for computing a layout; the other is a massively parallel genetic algorithm. The authors demonstrate the capabilities of the two algorithms by testing them on a variety of network-diagram layout problems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

The first observation of two structures consistent with resonances in the final states Λ_{b}^{0}π^{-} and Λ_{b}^{0}π^{+} is reported using samples of pp collision data collected by the LHCb experiment at sqrt[s]=7 and 8 TeV, corresponding to an integrated luminosity of 3 fb^{-1}. The ground states Σ_{b}^{±} and Σ_{b}^{*±} are also confirmed and their masses and widths are precisely measured.
An Experimental Study of the Formation of Tool Marks Made by Facet Diamond Cutting Tools in Single-Point Diamond Turning (2007)

The formation of tool marks in single-point diamond turning is a fundamental study of the effect of materials swelling and recovery on surface roughness on a machined surface. A series of orthogonal face cutting tests has been conducted among plate aluminum alloy, oxygen-free high conductivity copper and electroless nickel phosphorus under the same cutting conditions by the use of facet tools with different front clearance angles. The results show that the regular width of the undulating pattern in tool marks could be explained by side swelling and the micro-waviness within a tool mark is caused by burnishing and recovery.

Noninterferometric optical subtraction using reflection–electroabsorption modulators (1992)

A noninterferometric technique for optical subtraction is demonstrated that employs a multiple-quantum-well reflection-electroabsorption modulator and provides lower insertion loss, larger contrast ratio, and linearity over a larger dynamic range than similar techniques previously reported.
Rapid depletion of muscle progenitor cells in dystrophic mdx/utrophin−/− mice (2014)

Duchenne muscular dystrophy (DMD) patients lack dystrophin from birth; however, muscle weakness becomes apparent only at 3-5 years of age, which happens to coincide with the depletion of the muscle progenitor cell (MPC) pools. Indeed, MPCs isolated from older DMD patients demonstrate impairments in myogenic potential. To determine whether the progression of muscular dystrophy is a consequence of the decline in functional MPCs, we investigated two animal models of DMD: (i) dystrophin-deficient mdx mice, the most commonly utilized model of DMD, which has a relatively mild dystrophic phenotype and (ii) dystrophin/utrophin double knock-out (dKO) mice, which display a similar histopathologic phenotype to DMD patients. In contrast to age-matched mdx mice, we observed that both the number and regeneration potential of dKO MPCs rapidly declines during disease progression. This occurred in MPCs at both early and late stages of myogenic commitment. In fact, early MPCs isolated from 6-week-old dKO mice have reductions in proliferation, resistance to oxidative stress and multilineage differentiation capacities compared with age-matched mdx MPCs. This effect may potentially be mediated by fibroblast growth factor overexpression and/or a reduction in telomerase activity. Our results demonstrate that the rapid disease progression in the dKO model is associated, at least in part, with MPC depletion. Therefore, alleviating MPC depletion could represent an approach to delay the onset of the histopathologies associated with DMD patients.
