A dimensionless parameter model for arc welding processes (1994)

A dimensionless parameter model previously developed for C0{sub 2} laser beam welding has been shown to be applicable to GTAW and PAW autogenous arc welding processes. The model facilitates estimates of weld size, power, and speed based on knowledge of the material`s thermal properties. The dimensionless parameters can also be used to estimate the melting efficiency, which eases development of weld schedules with lower heat input to the weldment. The mathematical relationship between the dimensionless parameters in the model has been shown to be dependent on the heat flow geometry in the weldment.
Reentry attitude tracking via coupling effect-triggered control subjected to bounded uncertainties (2018)

The attitude tracking control issue for hypersonic reentry vehicle subjected to bounded uncertainties is investigated in this paper. The uncertainties are estimated by a disturbance observer with a simple structure whose parameter tuning methodology is provided to guarantee the system robustness. The coupling effect of the hypersonic reentry vehicle is analysed with a binary form based on a coupling effect indicator. The positive or negative value of indicator represents the harmful or beneficial coupling effect on the system. Then, a coupling effect-triggered control is developed to cancel the harmful couplings while utilising the beneficial couplings. The trigger point in the controller occurs when the property of the coupling effect happens to change. The specific criterion is introduced to quantify the performance improvement via the proposed scheme. Application to the hypersonic reentry tracking is presented to demonstrate the validity of the proposed method.
Evaluation of the need for simultaneous orthogonal gated setup imaging (2010)

Image-guided patient setup for respiratory-gated radiotherapy often relies on a pair of respiratory-gated orthogonal radiographs, acquired one after the other. This study quantifies the error due to changes in the internal/external correlation which may affect asynchronous (non-simultaneous) imaging. The dataset from eight patients includes internal and external coordinates acquired at 30Hz during multi-fraction SBRT treatments using the Mitsubishi RTRT system coupled with an external surrogate gating device. We performed a computational simulation of the position of an implanted fiducial marker in an asynchronous orthogonal image set. A comparison is made to the reference position, the actual 3D fiducial location at the initial time point, as would be obtainable by simultaneous orthogonal setup imaging at that time point. The time interval between the two simulated radiographic acquisitions was set to a minimum of 30, 60 or 90 seconds, based on our clinical experience. The setup position is derived from a combination of both the initial (AP) and the final (LR) simulated 2D images in the following way: LRsetup = LRinitial , SIsetup = SIinitial + (SIfinal - SIinitial)/2, APsetup = APfinal. The 3D error is then the magnitude of the vector from the initial (reference) position to the setup position. The calculation was done for every exhale phase in the data for which there was another one at least 30, 60 or 90 seconds later, at an amplitude within 0.5 mm from the first. A correlation between the time interval and the 3D error was also sought. The mean 3D error is found to be roughly equivalent for time intervals (tinterval) of 30, 60 and 90 seconds between the orthogonal simulated images (0.8 mm, 0.8 mm, 0.6 mm, respectively). The 3D error is less than 1, 2 and 3 mm for 77%, 89% and 98% of the data points, respectively. The actual time between simulated images turned out to be very close to tinterval, with 90% of the second simulated image acquisitions being completed within 38, 68 and 95 seconds of the first simulated image for tinterval of 30, 60 and 90 seconds, respectively. No correlation was found between the length of the time interval and the 3D error. When acquiring respiratory-gated radiographs for patient setup, only small errors should be expected if those images are not taken simultaneously.
Soil Moisture, Relative Humidity, and Bentazon Affect Imazethapyr Absorption and Translocation in Common Ragweed (Ambrosia artemisiifolia) (1999)

Soil moisture, relative humidity (RH), and the addition of bentazon were examined for effects on absorption and translocation of 14 C-imazethapyr in common ragweed. When common ragweed was growing under conditions of low soil moisture (-300 kPa), absorption of 14 C-imazethapyr was reduced from 51 to 42%. Translocation of 14 C-imazethapyr was not affected by soil moisture. In the absence of bentazon, absorption and translocation of 14 C-imazethapyr was similar at 65 and 85% RH 48 and 168 h after treatment. Bentazon decreased absorption of 14 C-imazethapyr from 61 to 26% at 65% RH and from 65 to 57% at 85% RH 168 h after treatment. Bentazon decreased translocation of 14 C-imazethapyr from 35 to 9% at 65% RH and from 30 to 21% at 85% RH when averaged over time. This reduction in the absorption and translocation of 14 C-imazethapyr when bentazon was added may result in a reduction in common ragweed control compared to imazethapyr alone when RH is 65% or lower.
Pharmacokinetics in Rat of P8, a Peptide Drug Candidate for the Treatment of Alzheimer’s Disease: Stability and Delivery to the Brain (2018)

Strategies to achieve a therapy for Alzheimer's disease (AD) aimed at reducing the effects of amyloid-β (Aβ) have largely involved inhibiting or modifying the activities of the β- or <i>γ</i>-secretases or by the use of monoclonal antibodies (MAb). We previously offered the potential for a new, early and effective approach for the treatment of AD by a strategy that does not target the secretases. We showed that a family of peptides containing the DEEEDEEL sequence and another independent peptide, all derived from the amino terminus of PS-1, are each capable of markedly reducing the production of Aβ <i>in vitro</i> and in mThy1-hAPP transgenic mice. These peptides gave a strong and specific binding with the ectodomain of amyloid-β protein precursor (AβPP) and did not affect the catalytic activities of β- or <i>γ</i>-secretase, or the level of AβPP. Critical to the development of any therapeutic for AD is the requirement that it is stable and can be delivered to the brain. We report here data on the metabolic stability and delivery to the rat brain of our lead candidate P8 by intravenous (IV), intranasal (IN), and subcutaneous (SC) administration. Pharmacokinetics (PK) of P8 in rat plasma and CSF following a single dose of P8 demonstrate that SC administration gives better absorption compared to IN and is the delivery method of choice for the further development of P8 as a clinical candidate.
Impact of proapoptotic proteins Bax and Bak in tumor progression and response to treatment (2003)

The cell death program, apoptosis, is currently viewed as the ultimate obstacle in cancer therapy. Inhibition of apoptosis is thought to be involved in both tumorigenesis and resistance to chemo- and radiotherapy. Considerable efforts are underway to design new tools capable of overcoming this inhibition. In this review, the current understanding of mechanisms of apoptosis in normal and tumor cells as well as possible or existing strategies designed to induce specific and efficient cell death in cancers are summarized.

Intracranial volume versus static and pulsatile intracranial pressure values in children with craniosynostosis (2019)

In this cohort of children with craniosynostosis, there was no significant association between ICV and ICP values prior to CVES and no significant association between change in ICV and ICP values after CVES in a subset of patients. Therefore, ICV could not reliably estimate the ICP values. The authors suggest that intracranial hypertension in childhood craniosynostosis may not be caused by reduced ICV alone but rather by a distorted relationship between ICV and the volume of intracranial content (brain tissue, CSF, and blood).
Holes in the Geofence: Privacy Vulnerabilities in “Smart” DNS Services (2021)

Smart DNS (SDNS) services advertise access to geofenced content (typically, video streaming sites such as Netflix or Hulu) that is normally inaccessible unless the client is within a prescribed geographic region. SDNS is simple to use and involves no software installation. Instead, it requires only that users modify their DNS settings to point to an SDNS resolver. The SDNS resolver “smartly” identifies geofenced domains and, in lieu of their proper DNS resolutions, returns IP addresses of proxy servers located within the geofence. These servers then transparently proxy traffic between the users and their intended destinations, allowing for the bypass of these geographic restrictions.
Upregulation of Ski in Fibroblast is Implicated in the Peroxisome Proliferator- Activated Receptor d-Mediated Wound Healing (2012)

This study demonstrates that Ski is a novel target gene for PPARδ and upregulation of Ski to promote fibroblast proliferation is implicated in the PPARδ-mediated wound healing.
Rates and activation parameters for dimethyl sulphoxide exchange with hexakis(dimethyl sulphoxide)-nickel(II), -cobalt(II), and -iron(III) ions (1983)

Natural-abundance 17O n.m.r. at 54.24 MHz has been used to measure the rates of dimethyl sulphoxide (dmso) exchange with [M(dmso)6]2+(M = Co or Ni) ions, and 90-MHz stopped-flow 1H Fouriertransform n.m.r., and 22.63-MHz 13C n.m.r. line broadening, to measure the rate of dmso exchange with [Fe(dmso)6]3+ ion. At 298.2 K the rate constants and associated activation parameters for the exchange of a single solvent molecule are: 10–3kexI/s–1= 445 ± 12, 16.5 ± 0.3, and 0.026 ± 0.002; ΔH‡/kJ mol–1= 49.0 ± 1.5, 49.2 ± 0.4, and 52.1 ± 0.7; ΔS‡/J K–1 mol–1= 28 ± 5, 0.9 ± 1.1, and –43 ± 3 for CoII, NiII, and FeIII respectively. A systematic method is proposed for adjusting the relative weights of data sets when simultaneously fitting ln(T2r–1) and Δωr, data to the Swift–Connick equations.
A test of the community conditioning hypothesis: Persistence of effects in model ecological structures dosed with the jet fuel jp-8 (2000)

Abstract The foundation of the community conditioning hypothesis, the persistence of effects, was tested in a series of microcosm experiments. Experiments were conducted with the water-soluble fraction of the turbine fuel JP-8 using the standard protocols for the standardized aquatic microcosm (SAM). A repeat trial was conducted using the SAM protocol but with a 126-d test period, twice the standard duration. The results were examined using a variety of conventional univariate, multivariate, and graphical techniques. The principal conclusions were as follows. Effects are persistent in these model ecological systems long after the degradation of the toxicant. Patterns of impacts are detectable at concentrations 15 times lower than an experimentally derived single-species EC50. The replicate experiments are not replicable in the specific, but the broad pattern of the disruption of algal- herbivore dynamics followed by more subtle effects are consistently repeated. The durability of the indirect effects and therefore the information about historical events appears to be a consistent feature of these microcosm systems. The identity of the treatment groups persists. The critical features of the community conditioning hypothesis—persistence of information within ecologicalsystems and the reappearance of patterns and therefore the nonequilibrium dynamics—are again confirmed. The implications of these findings for environmental toxicology, monitoring, and ecological risk assessment are discussed.
Efficient kinetic experiments in continuous flow microreactors (2018)

Flow chemistry is an enabling technology that can offer an automated and robust approach for the generation of reaction kinetics data. Recent studies have taken advantage of transient flows to quickly generate concentration profiles with various online analytical tools. In this work, we demonstrate an improved method where temperature and flow are transient throughout the reaction. It was observed that only two orthogonal temperature ramp experiments under the same transient flow condition were sufficient to characterize a Paal-Knorr (one step bimolecular) reaction within our chosen reaction space. This method further shortens the time and decreases the materials needed to collect sufficient kinetic data and provides a framework with which more complex kinetic studies could be performed.
A Class-E Tuned W-Band SiGe Power Amplifier With 40.4% Power-Added Efficiency at 93 GHz (2015)

A W-band power amplifier with Class-E tuning in a 0.13 μm SiGe BiCMOS technology is presented. Voltage swing beyond BV <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CBO</sub> is enabled by the cascode topology, low upper base resistance, and minimally overlapping current-voltage waveforms. At 93 GHz with 4.0 V bias, the peak power-added efficiency and saturated output power are measured to be 40.4% and 17.7 dBm, respectively. With the bias increased to 5.2 V, the peak power-added efficiency and saturated output power at 93 GHz are measured to be 37.6% and 19.3 dBm, respectively.
Synthesis and Antibacterial Evaluation of Novel 1,3,4-Oxadiazole Derivatives Containing Sulfonate/Carboxylate Moiety (2020)

<b>A</b>bstract: In order to discover new lead compounds with high antibacterial activity, a series of new derivatives were designed and synthesized by introducing a sulfonate or carboxylate moiety into the 1,3,4-oxadiazole structure. Antibacterial activity against two phytopathogens, <i>Xanthomonas oryzae</i> pv. <i>oryzae (Xoo)</i> and <i>Xanthomonas axonopodis</i> pv. <i>citri</i> <i>(Xac)</i>, was assayed in vitro. The preliminary results indicated that ten compounds including <b>4a-1</b>-<b>4a-4</b> and <b>4a-11</b>-<b>4a-16</b> had good antibacterial activity against <i>Xoo</i>, with EC<sub>50</sub> values ranging from 50.1-112.5 <i>µ</i>M, which was better than those of Bismerthiazol (253.5 <i>µ</i>M) and Thiodiazole copper (467.4 <i>µ</i>M). Meanwhile, <b>4a-1</b>, <b>4a-2</b>, <b>4a-3</b> and <b>4a-</b><b>4</b> demonstrated good inhibitory effect against <i>Xanthomonas</i> <i>axonopodis pv. citri</i> with EC<sub>50</sub> values around 95.8-155.2 <i>µ</i>M which were better than those of bismerthiazol (274.3 <i>µ</i>M) and thiodiazole copper (406.3 <i>µ</i>M). In addition, in vivo protection activity of compound <b>4a-2</b> and <b>4a-3</b> against rice bacterial leaf blight was 68.6% and 62.3%, respectively, which were better than bismerthiazol (49.6%) and thiodiazole copper (42.2%). Curative activity of compound <b>4a-2</b> and <b>4a-3</b> against rice bacterial leaf blight was 62.3% and 56.0%, which were better than bismerthiazol (42.9%) and thiodiazole copper (36.1%). Through scanning electron microscopy (SEM) analysis, it was observed that compound <b>4a-2</b> caused the cell membrane of <i>Xanthomonas oryzae</i> pv. <i>oryzae</i> ruptured or deformed. The present results indicated novel derivatives of 5-phenyl sulfonate methyl 1,3,4-oxadiazole might be potential antibacterial agents.

Robust Low-Boom Design Method Considering Off-Track Loudness (2021)

An efficient design method is proposed for robust low-boom design considering sonic boom loudness at both on-track and off-track positions. There exists an efficient design method for on-track low-boom design based on a reversed equivalent area distribution without using optimum design methods. The proposed method extends the existing method to consider off-track loudness. The characteristic of the proposed method is a conversion and a unification by weighted average. In the conversion, reversed equivalent area distributions at off-track positions are converted to that at the on-track position. In the unification by weighted average, converted distributions are unified into a single distribution based on loudness estimation using the F-function of the converted reversed equivalent area distribution so that sonic boom loudness at on-track and off-track positions can be balanced. Once the unified distribution is defined for the on-track position, the existing method can be applied. The proposed method is applied to a 50-seat class supersonic airliner, and the maximum loudness of front part of sonic-boom signature at both on-track and off-track positions is successfully reduced by 6.5dB in terms of Stevens Perceived Level Mark VII from 91.6dB to 85.1dB.
A One-Dimensional PCA Approach for Classifying Imbalanced Data (2015)

Background: Highly complex and computational intensive methods based on Synthetic Minority Over-sampling Technique (SMOTE) and more recently Learning Vector Quantization SMOTE (LVQ-SMOTE) have been proposed for classification problems of imbalanced biomedical data. This works presents a much simpler approach that is not computationally intensive and competes well with existing approaches. It uses principal component analysis (PCA) to generate a pseudo-variable as a linear combination of the features. From this one pseudo-variable, several classification methods are developed that classify directly based on very simple statistics. One method, the Mean Method (MM), classifies cases based on closeness to the means for the two classes from training data sets. When the number of features is very large, a feature reduction (FR) procedure is proposed to reduce misclassifications. In cases where the means of both classes are similar but their spread about their means are different, the Spread Method (SM) is proposed. A unique feature of this method is that one is able to vary the accuracy of classification between the two classes by changing the width of the window for allocation of cases. These proposed methods are found to perform well without the use of over-sampling techniques and multiple-fold cross validation.
Results: The MM or the MM with FR was compared directly to recently published results for LVQ-SMOTE on six (6) data sets and gave better or much better results in every case as measured by adding the percent of true positives to the percent of true negatives. The SM was compared with LVQ-SMOTE on two (2) data sets and operating windows widths were obtained that gave much better results for the SM over LVQ-SMOTE.
Conclusion: Given the simplicity, strengths, and performance of the proposed approach in comparison to current methods, these methods and procedures are recommended for use in classification of imbalanced biomedical data applications.
<title>Optical vortex solitons: generation, dynamics, and instabilities</title> (2000)

We analyze the properties of vortex solitons generated in Kerr and non-Kerr nonlinear optical media, including the vortex drift and rotation in a diffracting Gaussian beam. We also present our recent analytical and experimentally results on the vortex-induced break-up of a dark-soliton stripe, and discuss a connection of this phenomenon with the well-known Aharonov-Bohm effect in solids.
Molecular Sex Identification in Dioecious Hippophae rhamnoides L. via RAPD and SCAR Markers (2018)

The dioecious property of the sea buckthorn (<i>Hippophae rhamnoides</i> L.) prevents sex recognition via traditional observation at the juvenile stage, thus impeding breeding and economic cropping; A random amplified polymorphic DNA (RAPD) and a sequence characterized amplified region (SCAR) markers were used to identify the sexes. A total of 45 random decamer primers were used to screen genomic DNA pools of staminate and pistillate genotypes for genetic polymorphisms. One female sex-linked marker was identified. D15 (5′-CATCCGTGCT-3′) amplified a particular band of 885 bp, which showed polymorphism among staminate and pistillate genotype plants. The SCAR marker Hrcx-15 was obtained by sequencing the fragment. The alleles of 140 pistillate genotypes were examined but not of the 140 staminate genotypes discerned via taxonomy. Staminate and pistillate genotypes of sea buckthorn plants can be distinguished, using Hrcx-15 as a genetic marker for sex identification and for expediting cultivation for commercial applications.
An English language speech database at the University of Western Australia (2002)

The authors present a report on the content and status of a major speech database collection effort. The goal is to collect a useful set of speech material from a very large number of speakers. These speakers are drawn from a wide cross-section of the local community with a variety of ethnic and educational backgrounds. Speech materials include isolated digits and numbers, vowels and voiced phonemes, connected digits, and phonetically balanced sentences. Speech signals are encoded into 16-bit pulse code modulation (PCM) format and stored on Betamax format video tapes. In the seven months since this project started, speech from 100 speakers has been collected. A statistical breakdown of the backgrounds of the speakers is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Studies on the Bacterial Surface Structure of Gram-negative Bacteria and its Biological Active Substances (1962)

The endotoxin was obtained from the autolysate of Pseudomonas aeruginosa. It has very weakpyocine activity against several kinds of strains. The constituents of the endotoxin, a lipopolysaccharide-protein complex and DNA-RNA-polyribose phosphate complex, have no pyocineactivity. Isolated protein moiety (Orig. endot.-P) from the lipopolysaccharide-protein complex, however, has strong pyocine activity against various kinds of strains. The simple protein (LSAS) isolated from the cell wall of the bacteria has the same potency of pyocine activity and has the same spectrum against sensible strains as the protein moiety (Orig. endot.-P) derived from the autolysate. The lipopolysaccharide moiety of the endotoxin has nopyocine activity and it is easily combined with the protein (LSAS or Orig. endot.-P) and masked the pyocine activity of it.The LSAS anti-serum as well as the Orig. endot.-P anti-serum can neutralize the pyocine activities of the two proteins (LSAS and Orig. endot.-P) by each other. Absorption tests reveal the pyocine activities of both proteins are identical. The anti-serum of the lipopolysaccharide moiety can not neutralize any pyocine activities of both proteins. According to the results, it can be concluded that the pyocine isthe protein part of the endotoxin and that the activity may be masked in the cell wall of the bacteria as a result of combining with lipopolysaccharide.
