Relation-aware Graph Attention Model With Adaptive Self-adversarial Training (2021)

This paper describes an end-to-end solution for the relationship prediction task in heterogeneous, multi-relational graphs. We particularly address two building blocks in the pipeline, namely heterogeneous graph representation learning and negative sampling. Existing message passing-based graph neural networks use edges either for graph traversal and/or selection of message encoding functions. Ignoring the edge semantics could have severe repercussions on the quality of embeddings, especially when dealing with two nodes having multiple relations. Furthermore, the expressivity of the learned representation depends on the quality of negative samples used during training. Although existing hard negative sampling techniques can identify challenging negative relationships for optimization, new techniques are required to control false negatives during training as false negatives could corrupt the learning process. To address these issues, first, we propose RelGNN -- a message passing-based heterogeneous graph attention model. In particular, RelGNN generates the states of different relations and leverages them along with the node states to weigh the messages. RelGNN also adopts a self-attention mechanism to balance the importance of attribute features and topological features for generating the final entity embeddings. Second, we introduce a parameter-free negative sampling technique -- adaptive self-adversarial (ASA) negative sampling. ASA reduces the false-negative rate by leveraging positive relationships to effectively guide the identification of true negative samples. Our experimental evaluation demonstrates that RelGNN optimized by ASA for relationship prediction improves state-of-the-art performance across established benchmarks as well as on a real industrial dataset.
Profile analysis with amplitude-modulated nontarget components (1996)

This study was concerned with why amplitude modulation of nontarget components disrupts profile analysis. The 1-kHz target component was unmodulated whereas the nontarget components were unmodulated or sinusoidally amplitude modulated at a rate of 10 Hz. In experiment 1, thresholds were measured as a function of the modulation depth of the nontarget components for four different targets: One consisted of a long-duration tone and three consisted of multiple short-duration tones located at the peaks, valleys, or leading edges of the modulation cycles of the nontarget components. Although there were differences across the three subjects, thresholds typically increased with increasing modulation depth for all four targets, indicating that restricting profile analysis to particular points in the modulation cycle does not alleviate the effect of amplitude modulation. In experiment 2, the signal consisted of multiple short-duration tones; the nontarget components were unmodulated and presented at levels below or above the level of the target component (i.e., positive and negative pedestals were created). Although thresholds generally were worse when the target and nontarget components were unequal in level than when they were equal, the results suggest that this pedestal effect cannot account entirely for the effect of amplitude modulation on profile analysis. This conclusion was further substantiated by a supplemental experiment that used square-wave modulation. For the single subject tested, thresholds increased as modulation depth increased, regardless of whether or not the target and nontarget components were equal in level at the time of signal occurrence.
Novel Molecular Clusters Having Aluminum-Phosphorus, Aluminum-Arsenic, and Gallium-Arsenic Skeletons, and Synthesis of an Al4As6Li4 Rhombododecahedron (1998)

Starting from small building blocks, namely the primary silylarsanes/phosphanes and H3M–NMe3 (M=Al, Ga) and [LiAlH4], the M2E2 heterocycles 1 (M =Al, Ga, E=P,S) and the unusual aggregate 2 are accessible. Compound 1 readily loses NMe3 during thermolysis to give the title compounds 3, which possess a hexagonal prismatic M6E6 cluster skeleton. They are potentially interesting as cocatalysts for the co-oligomerization of ethene and CO.
Re-Emergent Tremor without Accompanying Rest Tremor in Parkinson’s Disease (2008)

Structure, Function, and Repair of the Liver (2017)

The liver is the central organ for metabolic homeostasis. Its main functions are the processing of nutrients from the intestinal tract, synthesis of proteins and hormones, biotransformation, excretion of bile, and regulation of energy metabolism. In addition, it has an endocrine and immunological function. The liver is divided into eight segments referring to the Couinaud system, each of which has an individual blood supply (arterial and portal venous) and biliary drainage, which is the basis for most modern liver surgery and live-related split liver transplantation. The unique, dual blood supply of the liver via the portal vein and hepatic artery not only provides for metabolism of nutrients and clearance of toxins from the splanchnic area, but also ensures the liver's oxygen supply by compensating for limited flow rates in the artery. Biliary development continues until 15 years of age and must be taken into account when interpreting histopathology in children and understanding liver disease. The main cellular constituent of the liver are hepatocytes, polar cells that consist of a basal region that communicates with the blood stream through the sinusoids, and an apical region that drains bile into the biliary canaliculi. Different histological liver units are defined by functional or anatomical criteria, and the functions of liver cells as well as oxygen supply vary considerably between regions in these units. The liver has a remarkable potential for regeneration after injury by replication of mature hepatocytes and cholangiocytes. This means that partial hepatectomy for liver tumors and live-related liver donation for transplantation are feasible options that maintain unimpaired liver function.
A responsive photonic crystal film sensor for the ultrasensitive detection of uranyl ions (2020)

As an effective nuclear energy resource, uranium plays an important role in industry and energy but the wastes of uranium also cause radioactive contamination, which is harmful to the environment and the human body. Herein, a responsive photonic crystal (PC) film sensor for the ultrasensitive and label-free detection of uranyl ions (UO<sub>2</sub><sup>2+</sup>) has been proposed, which is easy to construct and does not need to be combined with a hydrogel. The PC film is not pH-sensitive because it is obtained by the self-assembly of methyl methacrylate-acrylonitrile co-polymeric nanospheres (PMMA-AN). These nanospheres were modified with amidoxime groups, which have a good coordination ability with UO<sub>2</sub><sup>2+</sup>. The bindings between nanospheres and UO<sub>2</sub><sup>2+</sup> change the refractive index and disturb the face-centered cubic structure of the film, which leads to a decrease in the diffraction peak intensity of the PC film. The sensor works in the concentration range of 10 pM to 100 μM for UO<sub>2</sub><sup>2+</sup> determination and the decreased intensities of the diffraction peaks are linearly correlated with the logarithm of UO<sub>2</sub><sup>2+</sup> concentration in the range from 1 nM to 100 μM. Moreover, the sensor shows good selectivity for UO<sub>2</sub><sup>2+</sup> and can also perform the determination of UO<sub>2</sub><sup>2+</sup> in a real sample. The responsive PC film sensor shows great potential in the label-free and ultrasensitive detection of UO<sub>2</sub><sup>2+</sup>.
Double gate silicon-on-insulator transistors: n/sup +/-n/sup +/ gate versus n/sup +/-p/sup +/ gate configuration (2004)

We have studied electron mobility behavior in asymmetric double-gate silicon on insulator (DGSOI) inversion layers, and compared it to the mobility in symmetric double-gate silicon on insulator devices. The electron mobility curves in asymmetric DGSOI devices are shown to be considerably below the mobility curves corresponding to symmetric devices, in the whole range of silicon thicknesses. We show that the lack of symmetry in the asymmetric DGSOI structure produces the loss of the volume inversion effect. In addition, we show that as the silicon thickness is reduced, the conduction effective mass of electrons in asymmetric devices is lower than that in the symmetric case, but that the greater confinement of electrons in the former case produces a stronger increase in the phonon scattering rate, and in the surface roughness scattering rate.

An unusual 5S rRNA, from Sulfolobus acidocaldarius, and its implications for a general 5S rRNA structure (1981)

The nucleotide sequence of the 5S ribosomal RNA of the thermoacidophilic archaebacterium Sulfolobus acidocaldarius was determined. The high degree of evident secondary structure in the molecule has implications for the common higher order structure of other 5S rRNAs, both bacterial and eukaryotic.
Characteristics and Treatment of Hepatitis C Virus Infection in HIV-Coinfected Subjects (1998)

Hepatitis C virus (HCV) and HIV share the same parenteral routes of transmission. This common epidemiology explains the high frequency of combined infections by HCV and HIV. The aim of this review is to clarify some important issues dealing with the reciprocal impact of HIV and HCV-associated infections, including the variations in clinical, biologic, histopathologic, and virologic natural history of both infections. Insights gained may improve clinical care of and the therapeutic approach to HCV infection in HIV-coinfected subjects.
RGBD-HuDaAct: A color-depth video database for human daily activity recognition (2011)

In this paper, we present a home-monitoring oriented human activity recognition benchmark database, based on the combination of a color video camera and a depth sensor. Our contributions are two-fold: 1) We have created a publicly releasable human activity video database (i.e., named as RGBD-HuDaAct), which contains synchronized color-depth video streams, for the task of human daily activity recognition. This database aims at encouraging more research efforts on human activity recognition based on multi-modality sensor combination (e.g., color plus depth). 2) Two multi-modality fusion schemes, which naturally combine color and depth information, have been developed from two state-of-the-art feature representation methods for action recognition, i.e., spatio-temporal interest points (STIPs) and motion history images (MHIs). These depth-extended feature representation methods are evaluated comprehensively and superior recognition performances over their uni-modality (e.g., color only) counterparts are demonstrated.
Preliminary Design of a High Tc Superconducting Persistent Mode Current Switch (2003)

Persistent Mode Current Switches (PMCS) are made from coils of superconductor that in theory will provide zero conduction losses when closed. By causing a section of the superconductor to leave its superconducting state and become resistive, the switch is effectively opened. There are currently 3 methods to open a PMCS; 1) applying heat, 2) applying a magnetic field or 3) application of current above the critical current (Ic) of the tape. The first two methods are not suitable for power applications as the switching time is too slow. Recent work at the University of Wollongong and in literature has shown that by careful design, a switch using High Temperature Superconductors (HTS) and applying a high frequency current pulse can potentially achieve a switching time of less than 50μs.
Stress Concentration in Tubular Joints (1977)

Abstract Fatigue cracking caused by stress concentrations in tubular joints has been observed in some fixed platforms installed in hostile environments. platforms installed in hostile environments. Consequently, the ability to assess the magnitude of the stress concentration is a Prerequisite to dealing with the fatigue problem of tubular joints. This paper deals with the problem of computing the stress concentration in three types of simple, nonreinforced joints: T-joints, K-joints, and TK-joints. Semi-empirical equations are presented for estimating the stress concentration due to axial loads and bending moments. Introduction In off shore structures stress concentrations usually occur at the intersections of tubular members (i.e., tubular joints). For some joints, the stress concentration can produce a maximum stress at the intersection as high as 20 times the nominal stress acting in the members. Stress concentrations have aggravated the fatigue of tubular joints in many existing offshore structures. Therefore, an accurate computation of stress concentrations is of utmost importance in a tubular joint design. The first part of this paper presents a discussion of the finite-element analysis method and the associated computer program developed exclusively for the analysis of tubular joints. The second part of this paper describes the parameter study carried out by means of the computer program. Formulas for estimating stress-concentration factors for simple joints commonly used in offshore structures are derived from the results of the parameter study. The usage of the resulting formulas is illustrated by a numerical example. ANALYTICAL TECHNIQUE In offshore structures such as fixed platforms and semisubmersible drilling vessels, tubular members comprise the main load-carrying components. Examples of cracking and even complete separation at the intersections of such members have been cited previously throughout the literature. A typical example of such an intersection is shown in Fig. 1. The member of greatest diameter will be referred to as the chord. The smaller diameter members framing into the chord will be called branches. The sections of the chord wall lying within the branch intersection line (if present) will be called plugs. Fig. 2 shows the various simple joint types referred to in this paper. Because of the relative complexity of the geometrical configuration of tubular intersections as well as the thin-shell theory governing their behavior, reliable prediction of the stresses in such joints by analytical techniques has proven to be costly as well as difficult. Early attempts at analysis ranged from elementary strength-of-materials approaches such as the "punching shear" method to more complicated treatments that solve the governing equations by means of Fourier Series superposition.

A Screening, Brief Intervention, and Referral to Treatment Collaborative: Impact for Social Work Students (2019)

Screening brief intervention, and referral to treatment (SBIRT) is a clinical intervention empirically linked to reductions in substance usage. However, less is known on how to effectively train social work students on SBIRT. This study examines the impact of a SBIRT training administered to BSW and MSW students (N=228) at the University of Oklahoma. Based on exposure to the training, our evaluation measured changes on students’ objective knowledge of how to perform SBIRT and in attitudes toward practicing with substance users. Results indicated exposure to the training was associated with robust gains across variables and across classes. Such results suggest that the proffered SBIRT training is an effective means to educate social work students on substance abuse practice.
Synthesis of Imino Stabilized Iron Oxide Nanosensor for Selective Detection of Lead Ions (2023)

The present work describes the successful preparation of iron oxide nanoparticles (NSB1) stabilized with 4-((2-hydroxybenzylidene)amino)benzoic acid. The characterization has been achieved through ultraviolet visible (UV-Vis), fourier transform infra-red (FTIR) spectroscopy and scanning electron microscopy (SEM) with electron dispersive X-ray elemental analysis (EDX). These magnetic nanoparticles have exhibited significant chemosensing properties in the aqueous media to screen Cr3+, Cd2+, Li+, Co2+, Al3+, Pb2+, Ni2+ and Sr2+ ions. However, lead (Pb2+) ions have shown the highest selectivity as compared to other metal ions without any interference in the competitive ion study. The detection limit of Pb2+ ions was found to be 1.7 µM by this nanosensor. The binding ratio and stoichiometry was found to be 1:1 as measured by Job’s plot. The binding strength was also computed through Benesei-Hildebrand equation.
Catching spam before it arrives: domain specific dynamic blacklists (2006)

The arrival of any piece of unsolicited and unwanted email (spam) into a user&amp;apos;s email inbox is a problem. It results in real costs to organisations and possibly an increasing reluctance to use email by some users. Currently most spam prevention techniques rely on methods that examine the whole email message at the mail server. This paper describes research that aims to deny spam entry into the internal network in the first place.
IPv6 Renumbering - Security and Monitoring. D3.1 - Monitoring Framework (2007)

Renumbering is an integral part of the IPv6 protocol. This service is enabled by the Neighbor Discovery protocol. While offering several advantages, this protocol represents a serious security threat to the integrity of the network. The renumbering procedure can indeed create vulnerabilities in the network security by deploying a parallel routing infrastructure for a new prefix. This document contains a description of a complete monitoring framework architecture for monitoring the whole procedure and ensure it is done safely. This study was supported by CISCO Systems as part of the CISCO Applied Research and Developpement program.
Influence of priorities on the performance of a fast packet switch in the case of bursty traffic (1992)

Existing communication networks will be replaced by integrated networks which are able to handle various types of traffic and satisfying the needs of a large number of applications. In order to offer different service classes according to different service needs, priorities have been suggested to distinguish loss sensitive data from other traffic. This is necessary when - as in packet switched networks - physical connections are not dedicated to just one application, but data packets of a number of virual circuits are multiplexed across a physical link influencing each other in terms of delay and packet loss. This paper describes the needs of some communication services, priority schemes that were suggested to offer more than one service class and simulations that were made to get a feeling for the influence of highly bursty traffic on the performance of a fast packet switch. It will show how priorities influence traffic characteristics for bursty traffic.
Watermarking techniques for intellectual property protection (1998)

Digital system designs are the product of valuable effort and know-how. Their embodiments, from software and HDL program down to device-level netlist and mask data, represent carefully guarded intellectual property (IP). Hence, design methodologies based on IP reuse require new mechanisms to protect the rights of IP producers and owners. This paper establishes principles of watermarking-based IP protection, where a watermark is a mechanism for identification that is (i) nearly invisible to human and machine inspection, (ii) difficult to remove, and (iii) permanently embedded as an integral part of the design. We survey related work in cryptography and design methodology, then develop desiderata, metrics and example approaches — centering on constraint-based techniques — for watermarking at various stages of the VLSI design process.
[The prognostic value of circulating microRNA-29b in left ventricular hypertrophy in patients with hypertension]. (2019)

<b>Objective:</b> To analyze the relationship between the level of microRNA-29b in circulation and left ventricular hypertrophy in hypertensive patients. <b>Methods:</b> A total of 240 subjects from Henan Province People's Hospital from June 2015 to June 2018 were included in the present study. Among them, 160 were hospitalized patients, and were divided into two groups. Patients with simple hypertension and had no left ventricular hypertrophy (80 cases) were in the simple hypertension group (HBP-NLVH), and patients with hypertension combined with left ventricular hypertrophy (80 cases) were in the high blood pressure with left ventricular hypertrophy group (HBP-LVH). Normal control subjects (80 cases) were those with no hypertension and randomly selected from the medical center of Henan Province People's Hospital. Serum microRNA-29b expressions were detected by real time fluorescence quantitative PCR. The thickness of interventricular septum (IVSD) and left ventricular posterior wall thickness (LVPWD) were measured by echocardiography. <b>Results:</b> Compared with the normal control group (1.95±0.79), the relative expression of microRNA-29b in the patients both in the HBP-NLVH group (2.67±0.92) and the HBP-LVH group (5.12±1.23) was up-regulated, and the difference between normal control and patients was statistically significant (<i>P<</i>0.05). In patients, the microRNA-29b level in the HBP-LVH group was significantly higher than that in the HBP-NLVH group (<i>P<</i>0.05). The expression level of microRNA-29b was positively correlated with IVSD (<i>r=</i>0.71, <i>P<</i>0.05) and LVPWD (<i>r=</i>0.74, <i>P<</i>0.05), respectively. The sensitivity and specificity of serum microRNA-29b levels in the diagnosis of left ventricular hypertrophy in hypertension patients were 96.8% and 91.3%, respectively. <b>Conclusion:</b> Serum microRNA-29b level is elevated in hypertensive patients with left ventricular hypertrophy, and is positively correlated with left ventricular hypertrophy. The circulation microRNA-29b might be a useful biomarker with prognostic value in left ventricular hypertrophy in hypertension patients.
