Relationship between Rail Surface Irregularity and Dynamic Wheel Load (1992)

The main purpose of this study is to investigate the relationship between tread surface irregularities of rails and dynamic wheel loads. This investigation has been carried out by computer simulation and measuring tests on the service line. In the computer simulation, we investigated firstly the difference between linear spring and Hertzian spring in rail/wheel contact and secondly the difference between the whole rolling stock model and the one wheel model. In the measuring tests, three types of irregularities were artificially set up in the rail on a service line of East Japan Railway. The first type had a wave length of about 150 mm, the second one of about 1000 mm and the third one had a mixture of both these wave lengths. Through this study we checked the accuracy of the computer simulation against the measured results and also investigated the relationship between dynamic wheel load, train speed, wave length and wave height of tread surface irregularity of rail.

Beat-to-Beat Fetal Heart Rate Analysis Using Portable Medical Device and Wavelet Transformation Technique (2021)

A beat-to-beat Tele-fetal Monitoring and comparison with clinical data are studied with a wavelet transformation approach. Tele-fetal monitoring is a big progress toward a wearable medical device for a pregnant woman capable of obtaining prenatal care at home. We apply a wavelet transformation algorithm for fetal cardiac monitoring using a portable fetal Doppler medical device. Choosing an appropriate mother wavelet, 85 different mother wavelets are investigated. The efficiency of the proposed method is evaluated using two data sets including public and clinical. From publicly available data on PhysioBank, and simultaneous clinical measurement, we prove that the comparison between obtained fetal heart rate by the algorithm and the baselines yields a promising accuracy beyond 95%. Finally, we conclude that the proposed algorithm would be a robust technique for any similar tele-fetal monitoring approach.
“Post-Gay” Yet? The Relevance of the Lesbian and Gay Scene to Same-Sex Attracted Young People in Contemporary Australia (2015)

In recent years, the lesbian and gay "scene" of bars, nightclubs, and dance parties has been undergoing a structural decline in many Western cities. This article aimed to examine the relevance of the scene to same-sex attracted young adults amid these changes. An online survey was conducted with 572 same-sex attracted young women and men in Sydney. Only a minority of respondents participated in the scene at least weekly (16%), and the majority did not regard the scene as important to their leisure time (60%). However, respondents valued the scene as a space to connect with other same-sex attracted people and display same-sex affection without fear of hostility. Lesbian and gay identified respondents tended to be more socially engaged with the scene compared to other same-sex attracted respondents. The findings suggest that while the scene continues to be valued by many same-sex attracted young people, improved social attitudes have made participating in the scene less of an imperative.
Search for anomalous production of events with two photons and additional energetic objects at CDF (2010)

We present results of a search for anomalous production of two photons together with an electron, muon, $\ensuremath{\tau}$ lepton, missing transverse energy, or jets using $p\overline{p}$ collision data from $1.1--2.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity collected by the Collider Detector at Fermilab (CDF). The event yields and kinematic distributions are examined for signs of new physics without favoring a specific model of new physics. The results are consistent with the standard model expectations. The search employs several new analysis techniques that significantly reduce instrumental backgrounds in channels with an electron and missing transverse energy.
Graphene-Boosted, High-Performance Aqueous Zn-Ion Battery (2018)

Given their low cost and eco-friendliness, rechargeable Zn-ion batteries (ZIBs) have received increasing attention as a device with great potential for large-scale energy storage. However, the development of ZIBs with high capacities and long lifespans is challenging because of the dendritic growth of Zn and the absence of suitable cathode materials. Herein, we report a novel rechargeable aqueous Zn-ion battery (AZIB) that consist of Zn coated with reduced graphene oxide as the anode and V<sub>3</sub>O<sub>7</sub>·H<sub>2</sub>O/rGO composite as the cathode. The new AZIB exhibits excellent cycle stability with a high capacity retention of 79% after 1000 cycles. Moreover, it can deliver a high power density of 8400 W kg<sup>-1</sup> at 77 W h kg<sup>-1</sup> and a high energy density of 186 W h kg<sup>-1</sup> at 216 W kg<sup>-1</sup>, and the former is higher than those of previously reported AZIBs. Our work provides a new perspective in developing rechargeable ZIBs and would greatly accelerate the practical applications of rechargeable ZIBs.
Ferroelectric‐Driven Performance Enhancement of Graphene Field‐Effect Transistors Based on Vertical Tunneling Heterostructures (2016)

A vertical graphene heterostructure field-effect transistor (VGHFET) using an ultrathin ferroelectric film as a tunnel barrier is developed. The heterostructure is capable of providing new degrees of tunability and functionality via coupling between the ferroelectricity and the tunnel current of the VGHFET, which results in a high-performance device. The results pave the way for developing novel atomic-scale 2D heterostructures and devices.
Metabolic consequences of a reversed pH gradient in rat tumors. (1994)

We have previously demonstrated (M. Stubbs, Z. M. Bhujwalla, G. M. Tozer, L. M. Rodrigues, R. J. Maxwell, R. Morgan, F. A. Howe, and J. R. Griffiths, NMR Biomed., 5: 351, 1992) that the intracellular pH (pHi) of several rat tumors is higher (> pH 7.0) than that of the tumor extracellular fluid (pHe), in contrast to normal tissues (e.g., liver) in which pHi is lower than pHe. In this paper we confirm a pHe of 6.8 +/- 0.07 (SEM) in Morris hepatoma 9618a by an independent method and report the tissue content of other ions by both 31P magnetic resonance spectroscopy and by conventional analysis in hepatomas and livers in rats. Compared with liver, tissue Na+ was 2-fold higher and tissue K+ was lower. Tissue Ca2+ was 8-fold higher (7.4 +/- 4.3 mumol/g wet weight) and tissue Pi was 2-fold higher (8.5 +/- 1.3 mumol/g wet weight) suggesting the presence of insoluble calcium phosphate. Cl- was unchanged (approximately 40 mumol/g wet weight), whereas HCO3- was lower in the hepatoma (12.4 +/- 0.83 compared to 15.5 +/- 0.76 mumol/g wet weight). Total tissue Mg2+ was similar in both tissues, but free [Mg2+] (calculated by two different methods) was approximately 5-fold lower in the hepatoma. The ATP values were 3.5-fold and [NAD]/[NADH] 9-fold lower in the hepatoma. The results are compatible with the hypothesis that the chronic partial hypoxia of tumor tissue involves changes in the linked equilibria of many ions and metabolites and may help explain such pathologies as calcification.
System Architecture and Implementation of MIMO Sphere Decoders on FPGA (2008)

Multiple-input-multiple-output (MIMO) systems use multiple antennas in both transmitter and receiver ends for higher spectrum efficiency. The hardware implementation of MIMO detection becomes a challenging task as the computational complexity increases. This paper presents the architectures and implementations of two typical sphere decoding algorithms, including the Viterbo-Boutros (VB) algorithm and the Schnorr-Euchner (SE) algorithm. Hardware/software codesign technique is applied to partition the decoding algorithm on a single field-programmable gate array (FPGA) device. Three levels of parallelism are explored to improve the decoding rate: the concurrent execution of the channel matrix preprocessing on an embedded processor and the decoding functions on customized hardware modules, the parallel decoding of real/imaginary parts for complex constellation, and the concurrent execution of multiple steps during the closest lattice point search. The decoders for a 4times4 MIMO system with 16-QAM modulation are prototyped on a Xilinx XC2VP30 FPGA device with a MicroBlaze soft core processor. The hardware prototypes of the SE and VB algorithms show that they support up to 81.5 and 36.1 Mb/s data rates at 20 dB signal-to-noise ratio, which are about 22 and 97 times faster than their respective implementations in a digital signal processor.
Diagnosis of Early Mild Cognitive Impairment Based on Associated High-Order Functional Connection Network Generated by Multimodal MRI (2023)

Mild cognitive impairment (MCI) is highly likely to convert to Alzheimer’s disease (AD). The main approach to identifying MCI is using a functional connection network (FCN). Traditional FCN is used to study the correlation between two brain regions, but it lacks deeper brain interaction information. Neuroscientists found the internal functional activity pattern in the human brain is characterized by sparse, modular, and overlapping structures, and the FCN is restricted by the brain structural connection network (SCN). They can improve the estimation accuracy of FCN. Therefore, this article first constructs low order FCN (LFCN) based on brain sparse, modular, and overlapping activity patterns. Then, new high-order FCN (HFCN) is proposed based on the restrictive relationship between SCN and FCN. To combine high robustness of LFCN with high sensitivity of HFCN, a new combination strategy of LFCN and HFCN is proposed. It integrates the idea of brain modular and overlapping with the restricted relationship between SCN and FCN. Finally, the experimental results show that in early MCI (EMCI) recognition the best classification performance is acquired with an accuracy of 91.42%, which is better than similar methods. This method will be instrumental in the early recognition of clinical MCI.
Physical properties of Michigan Antrim Shale (1980)

The physical properties of approximately 225 core samples and 700 samples of well cuttings from the Antrim Shale formation in the Michigan Basin were measured. The properties included density, porosity, permeability, pore size distribution, specific surface, and thermal expansion. Measurements were made before and after roasting in air and in nitrogen. In general the properties showed little variation with depth or location within the sampling area. The average porosity was about 8 percent of which approximately one-half consisted of closed pores. The porosity increased by about a factor of two after roasting at 500/sup 0/C. The permeability was found to be very low, averaging about 0.008 millidarcies. Permeability was higher in the direction parallel to the bedding planes than in the direction perpendicular to the planes. After roasting at 500/sup 0/C the permeability increased by about a factor of ten. Measurements while heating from 20 to 225/sup 0/C showed only minor variations in permeability with temperature. The specific surface area of the shale is low, averaging about 0.5 square meters per gram. The pore size distribution is bimodal with most of the pore volume in the size ranges of 0.01 to 0.1 and 10 to 100 micrometers. The shale expands about one percent perpendicular to bedding and 0.2 percent parallel to bedding when heated to 500/sup 0/C. The average expansion coefficient is 0.0025 percent per /sup 0/C on heating and 0.0010 on cooling. Peaks in the heating curve occur at about 25/sup 0/C and 450/sup 0/C.
Fluorescent multiplex linkage analysis and carrier detection for Duchenne/Becker muscular dystrophy. (1992)

We have developed a fast and accurate PCR-based linkage and carrier detection protocol for families of Duchenne muscular dystrophy (DMD)/Becker muscular dystrophy (BMD) patients with or without detectable deletions of the dystrophin gene, using fluorescent PCR products analyzed on an automated sequencer. When a deletion is found in the affected male DMD/BMD patient by standard multiplex PCR, fluorescently labeled primers specific for the deleted and nondeleted exon(s) are used to amplify the DNA of at-risk female relatives by using multiplex PCR at low cycle number (20 cycles). The products are then quantitatively analyzed on an automatic sequencer to determine whether they are heterozygous for the deletion and thus are carriers. As a confirmation of the deletion data, and in cases in which a deletion is not found in the proband, fluorescent multiplex PCR linkage is done by using four previously described polymorphic dinucleotide sequences. The four (CA)n repeats are located throughout the dystrophin gene, making the analysis highly informative and accurate. We present the successful application of this protocol in families who proved refractory to more traditional analyses.
K‐space substitution: A novel dynamic imaging technique (1993)

A rapid dynamic imaging sequence has been developed in which only the 32 phase encoding steps that encode low spatial frequencies are collected for each dynamic image. These are substituted into a previously acquired, 128 x 128 raw data set prior to image reconstruction. In this way the dynamic information is retained while the overall appearance is improved in comparison with images obtained by zero filling to 128 x 128, leading to better qualitative evaluation. The limited k-space sampling means that the technique is most effective for large homogeneous areas of signal change since fine changes in contrast are imperfectly recorded.
Endogenous Thyrotropin and Triiodothyronine Concentrations in Individuals with Thyroid Cancer (2008)

These data confirm that higher TSH concentrations, even within the normal range, are associated with a subsequent diagnosis of thyroid cancer in individuals with thyroid abnormalities. This further supports the hypothesis that TSH stimulates the growth or development of thyroid malignancy during its early or preclinical phase. We also show for the first time that patients with thyroid cancer also have lower T(3) levels than patients with benign disease.
The JPL optical communications telescope laboratory (OCTL) test bed for the future optical Deep Space Network (2003)

Relative to RF, the lower power-consumption and lower mass of high bandwidth optical telecommunications make this technology extremely attractive for returning data from future NASA/JPL deep space probes.
Aluminum patterning by ion implantation (1980)

This is a preliminary report on the use of ion implantation to influence the etch rates of thin aluminum films, thus permitting fabrication of patterns in Al films by chemical etching.
A SPI Interface Module Verification Method Based on UVM (2020)

The serial peripheral interface (SPI) is an important module for realizing communication between the APB bus in the SOC chip and peripheral SPI devices. Therefore, efficient and sufficient verification of the function of the SPI module is very important for the design and manufacture of the SOC chip. In this article, a verification environment for SPI module is built based on universal verification methodology (UVM). By introducing the register abstraction layer (RAL), the efficiency of register attribute checking and configuration is greatly improved. In addition, the use of constrained random excitation and automatic result comparison function has realized the full verification of the SPI function, with a coverage rate of 100%. Finally, the verification environment of the SPI module has been successfully migrated to the SOC verification environment.
Independent Risk Factors of Catheter-Related Thrombosis (CRT) in Adult Cancer Patients: An Individual Patient-Level Data (IPD) Meta-Analysis of Randomized Clinical Trials and Prospective Cohort Studies (2008)

Abstract Purpose: Symptomatic catheter-related thrombosis (CRT) complicates roughly 5% of central venous catheter insertions in cancer patients. Recent studies have failed to show a reduction in CRT with routine use of pharmacologic thromboprophylaxis in all patients. We conducted a meta-analysis of individual patient-level data to identify independent, baseline risk factors of CRT that may help to select high-risk patients for prophylaxis. Methods: PubMed, EMBASE, CINAHL, CENTRAL, DARE, Grey literature databases were searched in all languages from 1995–2008. Only prospective studies and randomized controlled trials (RCTs) were included. The primary end-point was objectively confirmed symptomatic and asymptomatic CRT. Multivariate logistic regression analysis of 17 prespecified baseline characteristics was conducted. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated. Results: A total sample of 5636 subjects from 5 RCTs and 7 prospective studies was included in the analysis. Among these subjects, 425 CRT events were observed (8%). In multivariate logistic regression, the use of implanted ports as compared with peripherally implanted central venous catheters (PICC), decreased CRT risk (OR = 0.43; 95% CI, 0.23–0.80). Alternatively, past history of deep vein thrombosis (DVT) (OR = 2.03; 95% CI, 1.05–3.92), subclavian venipuncture insertion technique (OR = 2.16; 95% CI, 1.07–4.34), and improper catheter tip location (OR = 1.92; 95% CI, 1.22–3.02), increased CRT risk. Conclusions: CRT risk is increased with using PICC catheters, previous history of DVT, subclavian venipuncture insertion technique and improper positioning of the catheter tip. These factors may be useful for risk stratifying patients to select those for thromboprophylaxis. Prospective studies are needed to validate these findings.
PHYLOGENETIC ANALYSIS OF BREEDING SITE USE AND α‐AMANITIN TOLERANCE WITHIN THE DROSOPHILA QUINARIA SPECIES GROUP (1996)

The Drosophila quinaria group is unusual within the genus in that it comprises both mycophagous and nonmycophagous species. DNA sequence data from three regions of the mitochondrial genome were used to infer relationships among four mycophagous species and three that breed on decaying water plants. Phylogenetic analysis of these species show that breeding in mushrooms and tolerance of high levels of α-amanitin were the ancestral states within the group. Thus, breeding in decaying water plants and intolerance of α-amanitin are derived conditions. We also found that the D. quinaria species group does not comprise separate mycophagous and nonmycophagous clades, but rather that (1) the shift from mushrooms to decaying plants occurred on at least two occasions; or (2) mycophagy reevolved within a lineage that had previously shifted to breeding on plants. The correlation between mycophagy and α-amanitin tolerance is perfect across the species we have examined, indicating that there is no detectable time lag between an ecological shift to a new breeding site and correlated changes in biochemical adaptation. The genetic distance between the mycophagous D. recens and the nonmycophagous D. quinaria indicates that these species split only about 1 M.Y.B.P. In terms of α-amanitin tolerance, D. recens and D. quinaria are typical of other ecologically similar species within the group. Thus, evolutionary changes in α-amanitin tolerance can evidently occur on the order of about 1 million yr. Our data also indicate that, in comparison to other groups of Drosophila, the quinaria species group may be undergoing an adaptive radiation.
Plasmodium 18S rRNA of intravenously administered sporozoites does not persist in peripheral blood (2018)

Beyond the first few hours after injection, sporozoite-derived Plasmodium 18S rRNA was not detected in peripheral blood. Diagnostics based on 18S rRNA are unlikely to be confounded by sporozoite inocula in human clinical trials.
A New Parity-Based Migration Method to Expand RAID-5 (2013)

To expand the capacity of a RAID-5 array with additional disks, data have to be migrated between disks to leverage extra space and performance gain. Conventional methods for expanding RAID-5 are very slow because they have to migrate almost all existing data and recalculate all parity blocks. This paper proposes a new online expansion method for RAID-5, named parity-based migration (PBM). This method only migrates blocks that form a special parallelogram with one side consisting of only parity blocks. When adding m disks to a RAID-5 with n disks, PBM achieves the minimal data migration which only needs to move m/(n+m) of all data blocks. Furthermore, no parity blocks are recalculated during the expansion. After expansion, although the RAID is not a standard RAID-5 distribution, the parity blocks are distributed evenly. Experimental results based on extensive trace-driven show that, on average, PBM can reduce the time of expansion by 73.6 percent while only reduces the performance of the expanded RAID by 1.83 percent when compared with Multiple-Device (MD), a toolkit provided in Linux kernel.
Duplicate Detection and Audio Thumbnails with Audio Fingerprinting (2004)

Audio fingerprinting is a powerful tool for identifying either streaming or file-based audio, using a database of fingerprints. This paper presents two new applications: duplicate detection, whose goal is to identify duplicate audio clips in a set, even if they differ in compression quality or duration, and thumbnail generation, which aims at providing a representative short clip of a music track. Each application is self-contained in that it does not require an external database of fingerprints. Thanks to the robustness of the fingerprinting engine, both applications perform well.

A compact dual-tip STM design (2006)

A compact dual-tip scanning tunneling microscope (STM) design that achieves both rigidity and stability is presented. We constructed a prototype unit to perform tests in ambient conditions. The two STM tips were able to maintain a stable tunneling condition with the sample surface simultaneously. Topographic images of a fresh cleaved graphite were taken simultaneously from the two tips. A common feature found in both images indicates that the two tunneling spots are /spl sim/800 nm apart.
