Realization by impedance discontinuity of a unidirectional wave in a duct with harmonically perturbed uniform mean flow (2019)

This paper presents a study of intentionally induced acoustic mode complexity in rigid-walled ducts of separable geometry and with uniform mean flow. An intermediately located perforated plate conceptualized as an impedance discontinuity is employed to maximize the acoustic mode complexity, in turn producing a unidirectional traveling wave from the source to the impedance discontinuity. The impedance of the perforated plate for realization of a unidirectional traveling wave is derived analytically and is found to be a function of the modal wavenumbers, the Mach number of the mean flow, the position of the perforated plate, and the termination impedance. The conditions derived analytically are verified computationally by finite element analysis. A measure of acoustic mode complexity is defined and also evaluated from the finite element analysis. It is found that the realization of a unidirectional traveling wave is robust at low Mach number mean flows, except at the occurrence of resonances. The method presented in this work provides a strategy to control the transmission of acoustic energy in rigid-walled ducts of separable geometry in the presence of uniform mean flow.
Evaluation of Monoclonal and Oligoclonal Gammopathies in a Pediatric Population in a Major Urban Center (2014)

The significance and presence of a monoclonal or oligoclonal gammopathy in pediatric and young adult populations is distinct from that seen in adults.
Diffusion in conducting polymers (1987)

The diffusion of oxidising dopant gases into polyacetylene films has been studied. The process is complicated because it is influenced by the doping reaction, by swelling of the polymer by the gas and by degradation reactions of the polymer with the counter-ions. Electrochemical measurements of anion and cation diffusion in doped polymer give diffusion coefficients comparable with those for gaseous dopants. Diffusion coefficients for ions in polythiophene are reported. The results are discussed in terms of potential applications of these polymers.

Hydrothermal processing of rice husks: effects of severity on product distribution (2008)

Abstract BACKGROUND: Treatment in aqueous media (hydrothermal or autohydrolysis reactions) is an environmentally friendly technology for fractionating lignocellulosic materials. Rice husks were subjected to hydrothermal processing under a variety of operational conditions to cause the selective breakdown of xylan chains, in order to assess the effects of reaction severity on the distribution of reaction products. RESULTS: The effects of severity (measured by the severity factor, R 0 ) on the concentrations of the major autohydrolysis products (monosaccharides, xylo‐ and glucooligosaccharides, xylooligosaccharide substituents, acetic acid, acid‐soluble lignin and elemental nitrogen) were assessed. The interrelationship between the severity of treatment and molecular weight distribution was established by high‐performance size‐exclusion chromatography. Selected samples were subjected to refining treatments as ethyl acetate extraction and ion exchange for refining purposes, and the concentrates were assayed by high‐performance anion‐exchange chromatography and matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry. CONCLUSIONS The protein equivalent of the products present in liquors accounted for 43 to 51% of the protein present in the raw rice husks. The concentrations of glucose (derived from starchy material) and arabinose (split from the xylan backbone) were fairly constant with severity. Even in treatments at low severity, high molecular weight compounds derived from xylan accounted for a limited part of the stoichiometric amount. Operating under harsh conditions, about 50% of the total xylan‐derived compounds corresponded to fractions with a degree of polymerization (DP) &lt; 9. After refining, saccharides accounted for more than 90% of the non‐volatile components of the sample. The refined products showed a series of xylose oligomers up to about DP 13, and a series of acetylated xylose oligomers up to about DP 15. Copyright © 2008 Society of Chemical Industry

Preharvest Spray Hexanal Formulation Enhances Postharvest Quality in ‘Honeycrisp’ Apples by Regulating Phospholipase D and Calcium Sensor Proteins Genes (2021)

'Honeycrisp' (<i>Malus domestica</i> Borkh.), a premium applecultivar, is highly susceptible to bitter pit and decline in quality during long-term storage. In order to enhance the quality, an aqueous composition containing hexanal was applied as a preharvest spray. The effects of hexanal were assessed on the treated fruit and compared with Harvista<sup>TM</sup> (a sprayable 1-Methylcyclopropene based commercial formulation) applied and control fruit under both cold (2.5 °C; four months) and cold after room temperature storage (20 °C; 14 days) conditions. Color, firmness, and total soluble solids (TSS) did not show a significant change in response to any treatment at harvest, while abscisic acid (ABA) significantly reduced and tryptophan increased in response to hexanal, compared to Harvista<sup>TM</sup> and control. The treatment effects on quality traits were observed during storage. Both hexanal and Harvista<sup>TM</sup> sprayed apples had higher TSS under both cold and room temperature storage. In addition, both sprays enhanced firmness at room temperature storage. However, the effects of sprays on other quality traits showed a different pattern. Apples sprayed with hexanal had lower phospholipase D enzyme (PLD) activity, lower incidence of bitter pit, and decreased expression of <i>MdPLDα1</i> compared to Harvista<sup>TM</sup> and control. On the other hand, Harvista<sup>TM</sup> treated fruit produced lower ethylene. Both sprays decreased the expression of <i>MdPLDα4, MdCaM2, MdCaM4</i> and <i>MdCML18</i> genes. Generally, PLD alpha has a direct role in promoting fruit senescence, whereas the calcium senor proteins (CaM/CMLs) may involve in fruit ripening process via calcium and ethylene interactions. Therefore, improved postharvest qualities, including the lower incidence of bitter pit in hexanal treated 'Honeycrisp', may be associated with lower membrane damage due to lower PLD enzyme activity and decreased expression of <i>MdPLDα1</i> and <i>MdPLDα4</i> genes throughout the storage period.
Isolation and Characterization of Mammalian HDAC10, a Novel Histone Deacetylase (2002)

Acetylation of histone core particles plays an important role in modulating chromatin structure and gene expression. The acetylation status of the histone tails is determined by two opposing enzymatic activities, histone acetyltransferases and histone deacetylases (HDACs). Here we describe the isolation and characterization of HDAC10, a novel class II histone deacetylase. Molecular cloning and Northern blot analyses reveal that the HDAC10 transcript is widely expressed and subjected to alternative splicing. HDAC10 is both nuclear and cytoplasmic, a feature reminiscent of HDACs 4, 5, and 7. Distinct from other family members, HDAC10 harbors an amino-terminal catalytic domain and a carboxyl pseudo-repeat that shares significant homology with its catalytic domain. Mutational analysis reveals that transcriptional repression by HDAC10 requires its intrinsic histone deacetylase activity. Taken together, HDAC10 represents a distinct HDAC that may play a role in transcription regulation.
Human Perceivable Authentication: An Economical Solution for Security Associations in Short-Distance Wireless Networking (2007)

A challenge in secure pairing of two wireless devices is how to share a secret between the two devices in a user-friendly manner, as many users practically choose the simplest setup of no security. Various out-of-band (OOB) methods have been proposed in the literature, where either extra hardware is required (e.g. infrared device, digital camera, near-field communication device, USB flash drive, etc.) or wireless devices with a keyboard/display are assumed. In this paper, we propose a novel method of human perceivable authentication (HPA) that, without any extra hardware, achieves industry-standard security for user interface (UI) constrained devices. A feature of the proposed HPA scheme is the simplicity of user operation for device pairing: a user presses and releases a button on an initiating wireless device in concert with the on/off pattern of LED light on a correspondent wireless device. Simulation experiments have been performed to evaluate the usability aspect of the proposed HPA scheme.
“Tako‐Tsubo‐Like Left Ventricular Dysfuntion”: A clinical Entity Mimicking Acute Myocardial Infarction With a Favorable Prognosis (2004)

An emotionally‐distressed, elderly Caucasian woman presented with chest pain and hypertension. Electrocardiogram showed inferior ST‐segment elevation, and an urgent cardiac catheterization was performed. Coronary angiography revealed normal appearing coronary arteries; however, left ventriculography showed extensive left ventricular apical akinesis. The patient had a mild rise in cardiac enzyme levels indicative of myocardial injury. She was discharged after an uncomplicated in‐hospital course. One month later, the left ventricular wall motion abnormality had improved. In this report, the authors discuss this compilation of findings known as tako‐tsubo‐like left ventricular dysfunction.

Load plan selection for package express fleets. (2001)

A loader serves two roles during the loading process for package delivery. First, given a load plan, which is an assignment of regions to delivery vehicles, the loader takes each package to be delivered, one-by-one, reads the address, and assigns it to the proper vehicle, according to the load plan. Second, the loader can decide whether or not to change the load plan during the loading process. Changing a load plan involves the re-assignment of regions to vehicles and, when appropriate, removing packages from one vehicle and placing them on another vehicle. Moving already assigned packages takes time, delays fleet departure, and hence generates additional cost. However, load plan adjustment can better balance delivery workload, which reduces cost. The objective of the research presented is to aid the loader during the loading process in deciding whether or not the current load plan should be continued, and if not, identify a better load plan, assuming that the current package load of each delivery vehicle is known. The load plan selection process is modeled as a Markov decision process (MDP) and analyzed in Chapter 2. We present structured results for the expected cost-to-go function which lead to an improved algorithm for computing an optimal load plan policy. We describe the improved algorithm and compare it to traditional dynamic programming methods in Chapter 3. We present a heuristic, based on conditions for action elimination, that is computationally superior to the exact methods. In Chapter 4, we present a prototype decision support system (DSS) for load plan selection in package express. We develop a statistical model to reflect a more complex information state and describe the implementation of the statistical model in an actual operation. We model the load plan selection process for air packages and suggest a solution technique. Conclusions are presented in Chapter 5.
Identifying Fenton-Reacted Trimethoprim Transformation Products Using Differential Mobility Spectrometry (2018)

A transformation product of trimethoprim, a contaminant of emerging concern in the environment, is generated using an electro-assisted Fenton reaction and analyzed using differential mobility spectrometry (DMS) in combination with MS/MS techniques and quantum chemical calculations to develop a rapid method for identification. DMS is used as a prefilter to separate positional isomers prior to subsequent identification by mass spectrometric analyses. Collision induced dissociation of each DMS separated species is used to reveal fragmentation patterns that can be correlated to specific isomer structures. Analysis of the experimental data and supporting quantum chemical calculations show that methylene-hydroxylated and methoxy-containing phenyl ring hydroxylated transformation products are observed. The proposed methodology outlines a high-throughput technique to determine transformation products of small molecules accurately, in a short time and requiring minimal sample concentrations (<25 ng/mL).
321 DEVELOPMENT IN VIVO AND IN VITRO OF PORCINE OOCYTES FERTILIZED BY INTRACYTOPLASMIC INJECTION OF A FREEZE-DRIED SPERM HEAD (2004)

The present study investigated the development in vivo and in vitro of in vitro matured porcine oocytes injected with a freeze-dried (FD) boar sperm head. In mice, DNA damage was induced during the holding period after rehydration and before sperm injection (Wakayama, T. and Yanagimachi, R. 1998, Nat. Biotechnol., 16, 639–641). Here, we examined the relationship between duration of rehydration of FD sperm and in vitro development of FD sperm-injected porcine oocytes. We also assessed the in vivo developmental competence of the injected oocytes after embryo transfer. Ejaculated boar spermatozoa were suspended in Pig-FM (Suzuki, K. et al. 2002, Int. J. Androl. 25, 84–93) and sonicated for 1 min to separate sperm heads from the tails. An aliquot (100 µL) of the sperm suspension was put into a glass tube and then pre-cooled at -40°C for 6 h. Each tube was attached to a freeze-dry system (DuraDry µP, FTS Systems, Stone Ridge, NY, USA) for 12 h. The ampules were closed and stored at 4°C for more than 7 days before use. For rehydration, 100 µL of distilled water was added into the ampules. In Experiment I, we injected FD sperm heads which were kept for 0–60, 60–120, or 120–180 min after rehydration. At 1 h after the injection, the injected oocytes were stimulated with a DC pulse and cultured for 6 days. The rate of blastocyst formation and the number of cells in the blastocysts were examined. Embryos after in vitro fertilization (IVF) were evaluated as a control. As shown in Table 1, the rates of blastocyst formation were not different (by ?2 test) for duration of rehydration and the control. However, the cell numbers of FD groups were lower (P &amp;lt; 0.05; by Student's t-test) than that in the control. In Experiment II, oocytes injected with a single FD sperm head and stimulated were transferred to both oviducts of a total of ten recipient gilts. Two recipients were diagnosed as pregnant at Day 30 of gestation. At Day 39, one of the pregnant recipients had an abortion, and two fetuses were recovered. The other pregnancy was not maintained. The results suggest that oocytes fertilized with a single FD sperm head have competence to be implanted and to develop to the early fetal stage, and also that the duration for rehydration does not influence in vitro developmental ability in pigs.

Does platelet-derived growth factor-A chain stimulate proliferation of arterial mesenchymal cells in human atherosclerotic plaques? (1994)

Previous studies have indicated the focal presence of growth factors and focal low levels of cell proliferation in human atherosclerotic plaques. Using human carotid plaques and an antibody to platelet-derived growth factor (PDGF)-A chain, we have begun to assess growth factor significance by spatially correlating growth factor gene expression with actual cell proliferation. Since PDGF is a mitogen for smooth muscle and related cells and since inflammatory cells (eg, macrophages) can also proliferate in these lesions, it was important to exclude inflammatory cell proliferation from this consideration. Therefore, we have used a triple immunolabeling approach, combining the above anti-PDGF-A chain antibody with an inflammatory cell cocktail (CD68+CD45 for monocyte/macrophages and lymphocytes) and adding an anti-proliferating cell nuclear antigen (PCNA) antibody to mark proliferating cells. In the carotid atherosclerotic plaques, PDGF immunostaining was distributed focally, preferentially in the fibrous cap and vascularized regions, and was present in two distinct patterns: cytoplasmic and diffuse extracellular staining. When we considered colocalization within the same cells, cytoplasmic PDGF-A staining did not appear to colocalize with inflammatory markers. PCNA nuclear staining combined with PDGF cytoplasmic staining of the same cell was detected extremely rarely. Considering colocalization within the same microscopic fields, PDGF-A staining was detected more frequently than noninflammatory PCNA positivity. Quantitative logistic regression analysis demonstrated that localization in vascularized regions and (independently) the presence of PDGF-A are good predictors of noninflammatory cell proliferation, within the same microscopic fields. Therefore, PDGF-A and other factors especially associated with vascularized regions may be involved in the regulation of mesenchymal cell proliferation in human atherosclerotic plaques.
Voltage-clamped soft switching PWM inverter-type DC-DC converter for microwave oven and its utility AC side harmonics evaluations (2002)

A single-ended quasi-resonant zero voltage soft-switching inverter type DC-DC converter is used to drive the magnetron for a microwave oven. This converter is simple, downsizing, high efficiency and low cost in addition to simple control scheme. However, this power conversion circuit has to control its input power under a condition of ZVS in accordance with the variable frequency regulation. The heater current variation of the magnetron becomes large when the power regulation of this inverter is implemented. The regulation range of input power is to be in order to achieve ZVS operation. For high power application, the peak voltage of IGBT in this inverter becomes large. This paper presents a new topology of the voltage-clamped ZVS-PWM high-frequency inverter-fed DC-DC converter for driving a microwave oven. This paper also describes how to improve line current distortion and power factor on the utility AC power side. Because the anode current of the magnetron must not exceed 1.2 A, because of the lifetime of the magnetron, the voltage-clamped ZVS-PWM high-frequency inverter-fed DC-DC converter is implemented and evaluated under suppression conditions of the anode peak current of the magnetron.
MicroRNA‐196A‐2 polymorphisms and hepatocellular carcinoma in patients with chronic hepatitis B (2013)

Single nucleotide polymorphisms (SNPs) in microRNA (miR)-196a-2 have been suggested to contribute to susceptibility to various human cancers. The aim of this study was to determine whether polymorphisms of miRNA-196a-2 affect the clinical outcomes of hepatitis B virus (HBV) infection in Korean patients. Genotyping was performed for 1,439 Korean patients with either past or present HBV infection, including 404 control subjects who underwent spontaneous recovery and 1,035 subjects with chronic HBV (313 cases of chronic hepatitis B, 305 cases of cirrhosis of the liver, and 417 cases of hepatocellular carcinoma [HCC]). Genotyping results revealed that the polymorphism rs12304647A>C, which lies in the pri-miRNA region of miR-196a-2, has a significant minor allele frequency (0.210). Logistic analysis revealed that the rs12304647A>C SNP was associated with a significant protective effect against HCC in patients with chronic hepatitis (odds ratio [OR] = 0.70, P = 0.005 in a codominant model; OR = 0.73, P = 0.03 in a dominant model; OR = 0.31, P = 0.004 in a recessive model), and in the patients with cirrhosis (OR = 0.63, P = 0.0009 in a codominant model; OR = 0.66, P = 0.01 in a dominant model; OR = 0.25, P = 0.001 in a recessive model). A Cox relative hazards model with adjustments for age, gender, HBeAg status, and cirrhosis revealed that rs12304647A>C retained its association with HCC in a codominant model (relative hazards [RH] = 1.14, P = 0.05) and in a recessive model (RH = 1.44, P = 0.03). However, the miR-196a-2 rs12304647A>C SNP had no association with HBV clearance. In conclusion, the miR-196a-2 rs12304647 CC genotype had a protective effect against development of HCC in comparison to the AA or AC genotypes in patients with chronic hepatitis and cirrhosis.
