Signal-to-noise ratio of nondestructive photocurrent-detection readout in near-field photochromic memory: theoretical study (2002)

The signal-to-noise ratio (SNR) and possible data-transfer rate of nondestructive photocurrent-detection readout in near-field photochromic memory were calculated theoretically. The photocurrent-detection readout provided a much higher SNR and a higher data-transfer rate than those of conventional transmittance-detection readout. The SNR of the photocurrent-detection readout was dependent on the electric field applied to the medium and the potential barrier height between the photochromic recording layer and the photoabsorbing layer. A sufficient SNR was obtained under the conditions of an electric field of 2.5 V/m and a potential barrier height &lt;0.4 eV in land area. Photocurrent-detection readout is a promising method to achieve high SNR, high data-transfer rate, and ultrahigh recording density with nondestructive-readout capability.

Relationships between computational system performance and recognition system performance (2001)

The implementation of computational systems to perform intensive operations often involves balancing the performance specification, system throughput, and available system resources. For problems of automatic target recognition (ATR), these three quantities of interest are the probability of classification error, the rate at which regions of interest are processed, and the computational power of the underlying hardware. An understanding of the inter-relationships between these factors can be an aid in making informed choices while exploring competing design possibilities. To model these relationships we have combined characterizations of ATR performance, which yield probability of classification error as a function of target model complexity, with analytical models of computational performance, which yield throughput as a function of target model complexity. Together, these constitute a parametric curve that is parameterized by target model complexity for any given recognition problem and hardware implementation. We demonstrate this approach on the problem of ATR from synthetic aperture radar imagery using a subset of the publicly released MSTAR dataset. We use this approach to characterize the achievable classification rate as a function of required throughput for various hardware configurations.

Measurement of the lateral mobility of cell surface components in single living cells by fluorescence recovery after photobleaching (1976)

Abstract The use of fluorescence recovery after photobleaching (FRAP) techniques to monitor the lateral mobility of plant lectin‐receptor complexes on the surface of single, living mammalian cells is described in detail. FRAP measurements indicate that over 75% of the wheat germ agglutinin receptor (WGA‐receptor) complexes on the surface of human embryo fibroblasts are mobile. These WGA‐receptor complexes diffuse laterally (as opposed to flow) on the cell surface with a diffusion coefficient in the range of 2 × 10 −11 to 2 × 10 −10 cm 2 /sec. Both the percentage of mobile WGA‐receptor complexes and the mean diffusion coefficient of these complexes are higher than that obtained from earlier FRAP measurements of the mobility of concanavalin A‐receptor (Con A‐receptor) complexes in a variety of cell types. The possible reasons for the differing mobilities of WGA and Con A receptors are discussed.
Transmitter Identification Signal Detection Algorithm for ATSC 3.0 Single Frequency Networks (2020)

To effectively operate and maintain an existing single frequency network (SFN), the advanced television systems committee (ATSC) 3.0 transmission system has utilized a transmitter identification (TxID) technique. The TxID technique aims is to obtain the channel impulse response (CIR) of each transmitter independently to support the adjustment of the relative power level and delay offset of individual transmitters. The professional receiver can detect such CIR, but a commercial ATSC 3.0 receiver does not need to be necessarily decoded the TxID signal. Also, according to the ATSC 3.0 standard, the TxID signal is embedded into the preamble signal with an appropriately low injection level (IL), such that the impact on the preamble reception is negligible. This paper proposes an efficient TxID signal detection algorithm to enhance the individual CIR detection performance during the TxID analyzing process. The simulation results indicate that the proposed TxID signal detection algorithm can offer better individual CIR detection performance as compared to the conventional TxID signal detection algorithms, even though the IL of TxID signal is low.
On the Development of MCU-based ad hoc HW Interface Circuitry for Memristor Characterization (2020)

The evolution of resistive switching device (memristor) technology during the last ten years has shown the great potential of such emerging nanoelectronic devices in several potential applications, ranging from memory to computing and sensing. As memristor technology is continuously maturing, more devices become commercially available and thus accessible to investigators working on relevant research topics, as well as to university teaching labs and academics who wish to incorporate memristor-related experiments in their classrooms. However, experimental work on circuits with memristors requires particular caution and supervision, given that such devices are both highly sensitive (i.e., can easily burn out) and still quite expensive compared to other discrete circuit components. In this context, the development of integrated instrumentation solutions that provide a safe way to experimental work with memristors is becoming increasingly relevant, and some such tools have already reached the market. In this direction, we present some early results from our experience on the design and development of an instrumentation printed circuit board (PCB), designed to provide an ad hoc low-cost solution for measurements on memristors. The driving circuitry on the PCB is interfaced through a microcontroller-based system, providing easy programming and acquisition for a variety of measurements.
Effects of Static Magnetic Fields and Temperature Increase on 3D Magnetic Storage in Heated-Dot Magnetic Recording (Revised May 2021) (2021)

Using the Landau-Lifshitz-Gilbert (LLG) equation, we investigated the effects of static magnetic fields and increase in temperature on 3D magnetic storage in heated-dot magnetic recording (HDMR) in the write process. The recording medium of HDMR was assumed to have double recording layers in which the Curie temperature in the upper layer was lower than that in the lower layer. When the lower layer is recorded, the upper layer must be re-recorded. We then investigated the relationship between the spacing between recording layers and bit error rates. When the thicknesses of upper and lower layers were the same, the minimal spacing for recording nearly without error was 4 nm, thus achieving the critical static magnetic field values for recording different data in each layer.
Influence of instrumental parameters and sample preparation on mass‐analysed ion kinetic energy spectra with fast atom bombardment exemplified with the oxonium ion of peracetylated ribopyranose (1993)

Abstract When mass‐analysed ion kinetic energy (MIKE) spectra are required to discriminate between isomeric ions formed under conditons of fast atom bombardment (FAB) in the ion source, severe interference may be observed. The interfering peaks in MIKE spectra obtained with a reversed‐geometry instrument can arise from different sources. Moreover, the intensity distribution of the true ions from the selected precursor ion may depend strongly on the instrument being used. This means that the FAB–MIKE or collisionally induced dissociation (CID) spectrum is not an absolute characteristic of a particular ion. The [M + H − HOAc] + ion in the spectrum of peracetylated ribopyranose is used as an example to illustrate this and to trace and discuss the origin of the phenomena observed.
Sequence dependent fragmentation of peptides generated by MALDI quadrupole time-of-flight (MALDI Q-TOF) mass spectrometry and its implications for protein identification (2002)

A study has been undertaken to evaluate the usefulness of MALDI Q-TOF data for protein identification. The comparison of MS data of protein digests obtained on a conventional MALDI TOF instrument to the MS data from the MALDI Q-TOF reveal peptide patterns with similar intensity ratios. However, comparison of MS/MS Q-TOF data produced by nanoelectrospray versus MALDI reveals striking differences. Peptide fragment ions obtained from doubly charged precursors produced by nanoelectrospray are mainly y-type ions with some b-ions in the lower mass range. In contrast, peptide fragment ions produced from the singly charged ions originating from the MALDI source are a mixture of y-, b- and a-ions accompanied by ions resulting from neutral loss of ammonia or water. The ratio and intensity of these fragment ions is found to be strongly sequence dependent for MALDI generated ions. The singly charged peptides generated by MALDI show a preferential cleavage of the C-terminal bond of acidic residues aspartic and glutamic acid and the N-terminal bond of proline. This preferential cleavage can be explained by the mobile proton model and is present in peptides that contain both arginine and an acidic amino acid. The MALDI Q-TOF MS/MS data of 24 out of 26 proteolytic peptides produced by trypsin or Asp-N digestions were successfully used for protein identification via database searching, thus indicating the general usefulness of the data for protein identification. De novo sequencing using a mixture of 160/18O water during digestion has been explored and de novo sequences for a number of peptides have been obtained.
Measurements of mixed harmonic cumulants in Pb-Pb collisions at $\mathbf{\sqrt{{\textit s}_{\rm NN}}}=5.02$ TeV (2021)

Correlations between moments of different flow coefficients are measured in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV recorded with the ALICE detector. These new measurements are based on multiparticle mixed harmonic cumulants calculated using charged particles in the pseudorapidity region $|\\eta|&lt;0.8$ with the transverse momentum range $0.2 &lt; p_{\\rm T} &lt; 5.0$ GeV/$c$. The centrality dependence of correlations between two flow coefficients as well as the correlations between three flow coefficients, both in terms of their second moments, are shown. In addition, a collection of mixed harmonic cumulants involving higher moments of $v_2$ and $v_3$ is measured for the first time, where the characteristic signature of negative, positive and negative signs of four-, six- and eight-particle cumulants are observed, respectively. The measurements are compared to the hydrodynamic calculations using iEBE-VISHNU with AMPT and TRENTo initial conditions. It is shown that the measurements carried out using the LHC Run 2 data in 2015 have the precision to explore the details of initial-state fluctuations and probe the nonlinear hydrodynamic response of $v_2$ and $v_3$ to their corresponding initial anisotropy coefficients $\\varepsilon_2$ and $\\varepsilon_3$. These new studies on correlations between three flow coefficients as well as correlations between higher moments of two different flow coefficients will pave the way to tighten constraints on initial-state models and help to extract precise information on the dynamic evolution of the hot and dense matter created in heavy-ion collisions at the LHC.
Cerebral Histamine H1 Receptor Binding Potential Measured with PET Under a Test Dose of Olopatadine, an Antihistamine, Is Reduced After Repeated Administration of Olopatadine (2009)

The results may be interpreted as either intracerebral accumulation of olopatadine or H(1) receptor downregulation due to repeated administration. The study shows feasibility and potential value for PET in evaluating the pharmacologic effect of a drug not only after a single dose but also after repeated administration.
Utilization of sugar cane bagasse as a substrate for fatty acid production by Aurantiochytrium sp. (2022)

The genus Aurantiochytrium, a heterotrophic marine protist, produces significant amounts of polyunsaturated fatty acids and carotenoids and is promising as an alternative source of those lipids. This research aimed to utilize lignocellulosic biomass, which is abundant on land and does not compete with food supply, for fatty acid production by Aurantiochytrium limacinum strain SR21. Sugarcane bagasse soaked in diluted sulfuric acid was blasted by steam explosion and subsequently saccharified by the enzyme. When SR21 was cultivated in the medium containing saccharified liquid of sugarcane bagasse, the cell growth was almost abolished as compared with the control medium with the same glucose concentration, suggesting the presence of growth-inhibiting components in the saccharified liquid. The growth and fatty acid production of SR21 was significantly inhibited in the presence of furans and phenolic compounds previously reported to be generated by heat treatment of lignocellulosic biomass. Among them, furfural was detected in the bagasse saccharified liquid at the concentration that could inhibit the growth of SR21. Removal of such compounds by activated charcoal restored the cell growth and fatty acid productivity.
A6 neurons simultaneously modulate active expiration and upper airway resistance in rats (2019)

During rest, inspiration is an active phenomenon, whereas expiration is passive. Under conditions of high chemical drive, such as hypercapnia/acidosis, there is an increase in inspiratory activity, expiration becomes active and upper airway resistance is reduced. The locus coeruleus noradrenergic neurons (A6 neurons) are activated when exposed to elevated CO<sub>2</sub> /[H<sup>+</sup> ] levels and modulate respiratory brainstem neurons regulating ventilation. However, the role of A6 neurons in the control of upper airway resistance is not fully understood. We tested the hypothesis that A6 neurons contribute to the central generation of active inspiratory and expiratory responses and the associated changes in the motor nerves controlling upper airway resistance during hypercapnia/acidosis in rats. Using a perfused brainstem-spinal cord preparation, we inhibited A6 neurons using pharmacogenetics and evaluated the active expiratory (abdominal nerve), laryngeal (cervical vagus nerve), oropharyngeal (hypoglossal nerve) and inspiratory (phrenic nerve) motor nerve responses to hypercapnia/acidosis. Acute inhibition of A6 neurons did not produce significant changes in the respiratory pattern in normocapnia. However, the hypercapnia/acidosis-induced active expiratory response and the associated changes in the motor nerves responsible for control of oropharyngeal and laryngeal resistance, as well as the inspiratory response were all reduced after inhibition of A6 neurons. Our data demonstrate that A6 neurons exert an important excitatory synaptic drive to the central generation of both active inspiratory and expiratory activities and modulate the control of upper airway resistance during hypercapnia/acidosis.
Characteristics of on-line membrane extraction microtrap GC system as applied to air and water monitoring (1996)

A method referred to as on-line membrane extraction microtrap gas chromatography (OLMEM) is presented for sampling organic pollutants directly into a gas chromatograph. This system is applicable for both air and water matrices. The sampling of the volatile organic compounds (VOCs) was achieved by passing water or air samples through a silicone hollow fiber membrane. An on-line microtrap was used to concentrate and inject the isolated organics into a GC. The extraction characteristics and optimum operating conditions for the membrane extraction of VOCs from air and water matrices were compared. Parameters such as response profile, extraction efficiency, analytical response at different flow rates, and effect of temperature variation were studied. Reynold's number was successfully used to normalize the viscosity and density differences between water and air. © 1996 John Wiley & Sons, Inc.
Arrays of Regenerated Fiber Bragg Gratings in Non-Hydrogen-Loaded Photosensitive Fibers for High-Temperature Sensor Networks (2009)

We report about the possibility of using regenerated fiber Bragg gratings generated in photosensitive fibers without applying hydrogen loading for high temperature sensor networks. We use a thermally induced regenerative process which leads to a secondary increase in grating reflectivity. This refractive index modification has shown to become more stable after the regeneration up to temperatures of 600 °C. With the use of an interferometric writing technique, it is possible also to generate arrays of regenerated fiber Bragg gratings for sensor networks.

ARTHROSCOPIC TENOTOMY OF THE LONG HEAD OF THE BICEPS IN THE TREATMENT OF ROTATOR CUFF TEARS. CLINICAL AND RADIOGRAPHIC RESULTS OF 307 CASES (2010)

The long head of the biceps tendon has been proposed as a source of pain in patients with rotator cuff tears. The purpose of this study is to evaluate the objective, subjective, and radiographic results of arthroscopic biceps tenotomy in selected patients with rotator cuff tears. Three hundred seven arthroscopic biceps tenotomies were performed in patients with full thickness rotator cuff tears. All patients had previously failed appropriate nonoperative management. Patients were selected for arthroscopic tenotomy if the tear was thought to be irreparable or the patient was older and not willing to participate in the rehabilitation required following rotator cuff repair. One hundred eleven shoulders underwent a concomitant acromioplasty. The mean age at surgery was 64.3 years. The mean preoperative radiographic acromiohumeral interval measured 6.6 mm. Patients were evaluated clinically and radiographically at a mean 57 months follow-up (range 24 to 168 months). The mean Constant score increased from 48.4 points preoperatively to 67.6 points postoperatively (p 1.3 mm during the follow-up period and was associated with longer duration of follow-up (p

Coexpression characteristics of trehalose‐6‐phosphate phosphatase subfamily genes reveal different functions in a network context (2008)

Arabidopsis thaliana databases are available that highlight the behavior of the transcriptome under literally hundreds of experimental manipulations, making attempts possible that integrate this information into gene networks. We present and discuss the functioning of a gene network model generated using deposited microarray experiments. Based on a graphical Gaussian model, the network describes conditional coregulation of genes under a variety of external factors and abiotic, biotic and chemical treatments. In this study, we show an aspect of this network that pertains to functions of genes in families where all members appear to carry out the same biochemical reaction. Chosen in this study were 10 genes in the Arabidopsis genome encoding trehalose-6-phosphate phosphatases (TPPs). Nine of these genes were highlighted by the network. Generally, each TPP formed a network associated with genes that identify different functional categories. Thus, network structures were obtained that identified connections to carbon distribution, drought, cold, pathogen responses, calcium and reactive oxygen species/redox signatures, including transcriptional control genes that separated network graphs seeded with different TPP genes. The structure of the transcript coexpression networks, by associating diverse members of gene families into separate clusters, facilitates hypothesis building and in-depth studies of functions of individual genes in families.
