Safe Hydration Volume to Prevent Contrast-induced Acute Kidney Injury and Worsening Heart Failure in Patients With Heart Failure and Preserved Ejection Fraction After Cardiac Catheterization

Abstract: Few studies have investigated the efficacy and safety of hydration to prevent contrast-induced acute kidney injury (CI-AKI) and worsening heart failure (WHF) after cardiac catheterization in heart failure and preserved ejection fraction (HFpEF; HF and EF ≥50%) patients. We recruited 1206 patients with HFpEF undergoing cardiac catheterization with periprocedural hydration volume/weight (HV/W) ratio data and investigated the relationship between hydration volumes and risk of CI-AKI and WHF. Incidence of CI-AKI was not significantly reduced in individuals with higher HV/W [quartile (Q) 1, Q2, Q3, and Q4: 9.7%, 10.2%, 12.7%, and 12.2%, respectively; P = 0.219]. Multivariate analysis indicated that higher HV/W ratios were not associated with decreased CI-AKI risks [Q2 vs. Q1: odds ratio (OR), 0.95; Q3 vs. Q1: OR, 1.07; Q4 vs. Q1: OR, 0.92; all P > 0.05]. According to multivariate analysis, higher HV/W significantly increased the WHF risk (Q4 vs. Q1: adjusted OR, 8.13 and 95% confidence interval, 1.03–64.02; P = 0.047). CI-AKI and WHF were associated with a significantly increased risk of long-term mortality (mean follow-up, 2.33 years). For HFpEF patients, an excessively high hydration volume might not be associated with lower risk of CI-AKI but may increase the risk of postprocedure WHF.
Finding New Music: A Diary Study of Everyday Encounters with Novel Songs

This paper explores how we, as individuals, purposefully or serendipitously encounter “new music” (that is, music that we haven’t heard before) and relates these behaviours to music information retrieval activities such as music searching and music discovery via use of recommender systems. 41 participants participated in a three-day diary study, in which they recorded all incidents that brought them into contact with new music. The diaries were analyzed using a Grounded Theory approach. The results of this analysis are discussed with respect to location, time, and whether the music encounter was actively sought, or occurred passively, and design implications for music information retrieval software, including an extension of “laid back” searching are outlined.
High-performance simulations of continuously variable transmission dynamics

The paper describes a parallel computational model simulating continuously variable transmission (CVT) dynamics. A specific feature of the CVT model is the combination of relatively small problem sizes (about 1000 unknowns) and high computational costs (up to several weeks of sequential code computations for a thirty seconds simulation period). The main source of computational complexity here is the calculation of non-linear contact forces acting between transmission parts at each step of the explicit time integration procedure. Below we analyze simulation workflow and runtime load distribution among the application modules. Based on the profiling data, we present a task parallel multithreaded implementation of the model over shared memory and discuss steps towards further parallelization.
Fault Reconstruction and Fault-Tolerant Control via Learning Observers in Takagi–Sugeno Fuzzy Descriptor Systems With Time Delays

This paper addresses the problems of observer-based fault reconstruction and fault-tolerant control for Takagi-Sugeno fuzzy descriptor systems subject to time delays and external disturbances. A novel fuzzy descriptor learning observer is constructed to achieve simultaneous reconstruction of system states and actuator faults. Sufficient conditions for the existence of the proposed observer are explicitly provided. Utilizing the reconstructed fault information, a reconfigurable fuzzy fault-tolerant controller based on the separation property is designed to compensate for the impact of actuator faults on system performance by stabilizing the closed-loop system. In addition, the design of the fault reconstruction observer and the fault-tolerant controller is formulated in terms of linear matrix inequalities that can be conveniently solved using convex optimization techniques. Finally, simulation results on a truck-trailer system are presented to verify the effectiveness of the proposed approaches.
Determination of Semiconductor Type and Optical Properties of SnO2:F(FTO) and SnO2:In(ITO)

Transparent and conducting oxide (TCO) glass electrode is the essential part of solar cell system. Fluorinedoped tin oxide (SnO2:F) (FTO) and indium-doped tin oxide (SnO2:In) (ITO) are TCO layers of glass electrode. In this work, type of semiconductor has been determined by hot point probe method and optical properties of FTO and ITO have been studied to improve the performance of solar cell efficiency by UV-VIS spectroscopy. The comparison of optical properties of FTO and ITO shows that ITO has low absorbance, high transmittance and low reflectance. The bandgap energy of FTO is 3.65 eV and that of ITO is 3.75 eV.
Universal Dependencies to Logical Form with Negation Scope

Many language technology applications would benefit from the ability to represent negation and its scope on top of widely-used linguistic resources. In this paper, we investigate the possibility of obtaining a first-order logic representation with negation scope marked using Universal Dependencies. To do so, we enhance UDepLambda, a framework that converts dependency graphs to logical forms. The resulting UDepLambda\lnot is able to handle phenomena related to scope by means of an higher-order type theory, relevant not only to negation but also to universal quantification and other complex semantic phenomena. The initial conversion we did for English is promising, in that one can represent the scope of negation also in the presence of more complex phenomena such as universal quantifiers.
Long Term Thermo-mechanical Prediction of Banana Stem Particulate Reinforced PVC Composite as Piping Material

A banana particulate reinforced polyvinyl chloride (PVC) composite was developed with considerabley low cost materials having an overall light-weight and good mechanical properties. The specimen composite material was produced with the banana (stem) particulate as reinforcement using compression molding. The composition with optimum mechanical property (42MPa) was determined at 8, 72 and 20% formulation of banana stem particulates (reinforcement), PVC (matrix) and Kankara clay (filler) respectively with corresponding density of 1.24g/cm 3 and tensile strength of 42MPa. Thermal analyses of the composited showed that the thermal stability of PVC was increased by 27.8% and is thermally stable up to a temperature of 370oC. It was established that Long term TTS (time-temperature-superposition) performance prediction increases with decrease in operating temperature with the best determined at lowest considered temperature of 40oC having a corresponding reduced stiffness of 1GPa at an estimated period in excess of 100 years of usage. The composite could be used as a transportation and distribution piping material for water (to domestic houses) and fuel (to city centers) where ambient temperature does not exceed 50oC.
RUCAM in Drug and Herb Induced Liver Injury: The Update

RUCAM (Roussel Uclaf Causality Assessment Method) or its previous synonym CIOMS (Council for International Organizations of Medical Sciences) is a well established tool in common use to quantitatively assess causality in cases of suspected drug induced liver injury (DILI) and herb induced liver injury (HILI). Historical background and the original work confirm the use of RUCAM as single term for future cases, dismissing now the term CIOMS for reasons of simplicity and clarity. RUCAM represents a structured, standardized, validated, and hepatotoxicity specific diagnostic approach that attributes scores to individual key items, providing final quantitative gradings of causality for each suspect drug/herb in a case report. Experts from Europe and the United States had previously established in consensus meetings the first criteria of RUCAM to meet the requirements of clinicians and practitioners in care for their patients with suspected DILI and HILI. RUCAM was completed by additional criteria and validated, assisting to establish the timely diagnosis with a high degree of certainty. In many countries and for more than two decades, physicians, regulatory agencies, case report authors, and pharmaceutical companies successfully applied RUCAM for suspected DILI and HILI. Their practical experience, emerging new data on DILI and HILI characteristics, and few ambiguous questions in domains such alcohol use and exclusions of non-drug causes led to the present update of RUCAM. The aim was to reduce interobserver and intraobserver variability, to provide accurately defined, objective core elements, and to simplify the handling of the items. We now present the update of the well accepted original RUCAM scale and recommend its use for clinical, regulatory, publication, and expert purposes to validly establish causality in cases of suspected DILI and HILI, facilitating a straightforward application and an internationally harmonized approach of causality assessment as a common basic tool.
Rat brain CYP2D activity alters in vivo central oxycodone metabolism, levels and resulting analgesia

Oxycodone is metabolized by CYP2D to oxymorphone. Despite oxymorphone being a more potent opioid‐receptor agonist, its contribution to oxycodone analgesia may be minor because of low peripheral production, low blood–brain barrier permeability and central nervous system efflux. CYP2D metabolism within the brain may contribute to variation in central oxycodone and oxymorphone levels, thereby affecting analgesia. Brain CYP2D expression and activity are subject to exogenous regulation; nicotine induces rat brain, but not liver, CYP2D consistent with higher brain CYP2D in smokers. We assessed the role of rat brain CYP2D in orally administered oxycodone metabolism (in vivo brain microdialysis) and analgesia (tail‐flick test) by inhibiting brain CYP2D selectively with intracerebroventricular propranolol (mechanism‐based inhibitor) and inducing brain CYP2D with nicotine. Inhibiting brain CYP2D increased brain oxycodone levels (1.8‐fold; P < 0.03) and analgesia (1.5‐fold AUC0–60; P < 0.001) after oxycodone, while inducing brain CYP2D increased brain oxymorphone levels (4.6‐fold; P < 0.001) and decreased analgesia (0.8‐fold; P < 0.02). Inhibiting the induced brain CYP2D reversed the change in oxycodone levels (1.2‐fold; P > 0.1) and analgesia (1.1‐fold; P > 0.3). Brain, but not plasma, metabolic ratios were affected by pre‐treatments. Peak analgesia was inversely correlated with ex vivo brain (P < 0.003), but not hepatic (P > 0.9), CYP2D activity. Altering brain CYP2D did not affect analgesia from oral oxymorphone (P > 0.9 for AUC0–60 across all groups), which is not a CYP2D substrate. Thus, brain CYP2D metabolism alters local oxycodone levels and response, suggesting that people with increased brain CYP2D activity may have reduced oxycodone response. Factors that alter individual oxycodone response may be useful for optimizing treatment and minimizing abuse liability.

The infinite HMM for unsupervised PoS tagging

We extend previous work on fully unsupervised part-of-speech tagging. Using a non-parametric version of the HMM, called the infinite HMM (iHMM), we address the problem of choosing the number of hidden states in unsupervised Markov models for PoS tagging. We experiment with two non-parametric priors, the Dirichlet and Pitman-Yor processes, on the Wall Street Journal dataset using a parallelized implementation of an iHMM inference algorithm. We evaluate the results with a variety of clustering evaluation metrics and achieve equivalent or better performances than previously reported. Building on this promising result we evaluate the output of the unsupervised PoS tagger as a direct replacement for the output of a fully supervised PoS tagger for the task of shallow parsing and compare the two evaluations.
An All‐Elastomeric Transparent and Stretchable Temperature Sensor for Body‐Attachable Wearable Electronics

A transparent stretchable (TS) gated sensor array with high optical transparency, conformality, and high stretchability of up to 70% is demonstrated. The TS-gated sensor array has high responsivity to temperature changes in objects and human skin. This unprecedented TS-gated sensor array, as well as the integrated platform of the TS-gated sensor with a transparent and stretchable strain sensor, show great potential for application to wearable skin electronics for recognition of human activity.
Characterization of the Specificity of Imidazoline I-1 Receptor Antibody for Subtype of Imidazoline Receptors In Vitro

Abstract Specific antibodies are essential in the study of receptor protein. Gene matching shows that Nischarin (NISCH) is a mouse homologue of human imidazoline receptor antisera-selective (IRAS) protein, a viable candidate for imidazoline I-1 receptor. However, selectivity of this antibody against imidazoline I-2 or imidazoline I-3 receptors remained obscure. At first, an intracerebroventricular (ICV) injection of anti-NISCH antibody blocked the blood pressure lowering action of rilmenidine (I-1 receptor agonist) in spontaneous hypertensive rat (SHR). However, the same injection of anti-NISCH antibody showed no effect in SHR treated with clonidine (α2 agonist). In order to clarify the selectivity of anti-NISCH antibody for each subtype of imidazoline receptors, this anti-NISCH antibody was subjected to the lysate of organs isolated from Wistar rats including cortex, hippocampus, cerebellum, and brain stem as central nervous tissues, and heart, liver, pancreas, skeletal muscle, kidney, prostate, and bladder as peripheral tissues. The results show that anti-NISCH antibody positively reacted with all tissues including heart, pancreas, skeletal muscle, kidney and bladder by Western blot analysis. Also, the blotting spots for anti-NISCH antibody show a concentration-dependent manner. Moreover, anti-NISCH antibody blocked the action of glucose uptake induced by 2-BFI (I-2 receptor agonist) in L6 cells. Taken together, the obtained data suggest that anti-NISCH antibody can be used not only for imidazoline I-1 receptor but also for I-2 and I-3 subtypes in immunoassays.
3D‐Printed, Superelastic Polypyrrole–Graphene Electrodes with Ultrahigh Areal Capacitance for Electrochemical Energy Storage

Disruptive custom electronics require a transformation in energy storage systems from traditional thin‐film units to shape conformable 3D components. However, current thick electrodes suffer from uncontrollable geometries and architectures, which lead to ion diffusion limitations, and poor mechanical properties. Here, designed, superelastic polypyrrole (PPy)‐coated graphene aerogel (GA) electrodes are fabricated via 3D printing and polymer self‐assembly methods. This resilient GA template (up to 90% compression) can be printed into any desired shape including engineered 3D architectures with periodic macropores, which promote the uniform deposition and adhesion of PPy onto the support. The coated PPy thin film increases the specific gravimetric capacitance of the GA electrode from 14 to 395 F g−1 with 90% retention after 5000 charging–discharging cycles. The capacitance remains the same value after 100 times compression cycles. It also improves the compressive strength by one order of magnitude from 0.14 to 2.4 MPa. Areal capacitance and energy density of the PPy–GA electrode are 2 F cm−2 and 0.78 mWh cm−2, respectively, which to the best of the knowledge break the record for compressible electrodes, respectively. This approach enables the fabrication of complex architectured energy storage modules with enhanced compressibility, ultrahigh areal electrochemical performance, and excellent cyclability.
An Untagged Human Hand Motion Classification by Pyroelectricity

Pyroelectric sensors are the most suitable for detecting human motions because they are sensitive to human motions induced variances in the infrared radiation. A pyroelectric sensor array is designed and used to build an event-time sequence in an infrared radiation domain. Then, the sequence is used to contrast with a password sequence for further recognizing human hand motions. This is applied on the intelligent life for controlling doors to open or close as a pyroelectric lock. For estimating the functions of the pyroelectric lock, six password sequences are used to control the proposed device via discreet manipulation of six persons. The experimental results verify the feasibility and efficacy of the proposed design. The false recognition is lower than 2%.
What good are ‘Nominalkomposita’ for ‘noun compounds’: Multilingual Extraction and Structure Analysis of Nominal Compositions using Linguistic Restrictors

Finding a definition of compoundhood that is cross-lingually valid is a non-trivial task as shown by linguistic literature. We present an iterative method for defining and extracting English noun compounds in a multilingual setting. We show how linguistic criteria can be used to extract compounds automatically and vice versa how the results of this extraction can shed new lights on linguistic theories about compounding. The extracted compound nouns and their multilingual contexts are a rich source that serves several purposes. In an additional case study we show how the database serves to predict the internal structure of tripartite noun compounds using spelling variations across languages, which leads to a precision of over 91%.
Epidemiology, etiology, and prevention of esophageal squamous cell carcinoma in China

Esophageal cancer is one of the most fatal diseases worldwide mainly because of its rapid progression and poor prognosis. Although the incidence of esophageal adenocarcinoma has markedly risen in North America and Europe in the past several decades, esophageal squamous cell carcinoma is still the predominant subtype of esophageal cancer, especially in China. It accounts for more than 90% of all esophageal squamous cell carcinoma cases in China. Geographical differentiation is one of the most distinctive characteristics of esophageal cancer. The progression, risk factors, and prognosis of these two subtypes of esophageal cancer differ. This study reviews the epidemiology, etiology, and prevention of esophageal squamous cell carcinoma in China, thereby providing systematic references for policy-makers who will decide on issues of esophageal cancer prevention and control.
Research Statement Sonar Image Processing and Analysis

Overview My image processing and computer vision history begins from my senior year in the college. I was lucky enough to be able to join the image processing group in Dept. Control & Instrumentation Engineering (Seoul National University) as the only undergraduate student working for a graduate school lab in the whole department. I started to learn about frame grabber boards, DSP and GSP chips, image processing algorithms, etc. and began to write image processing libraries and software packages. Since then (until now), I’ve been studying all kinds of image processing and computer vision theories and technologies. I studied 3D surface data acquisition and modeling for my Master’s degree, and I studied image processing via partial differential equations (PDE’s) for my Ph.D. I’ve written dozens of image processing and computer vision software packages for a number of projects. Even after I joined Summus, Inc. (Raleigh, NC), I worked on a US Navy project for Sonar image processing and analysis. Recently, as our company changed the business direction towards mobile application development, I had to change my focus to various other problems for a while even though a big portion of the work was still dealing with images (e.g. wallpaper applications and photo sharing applications). In this line of work, I had to learn many different fields, such as embedded programming, server-client programming, software engineering, vector graphics, geographical information system (GIS), user interface design issues, image compression, efficient graphic algorithms, etc. I think it was a great chance for me to broaden my eyesight to a wide variety of fields of studies. Following sections will briefly describe my history of research in various topics, and my plan for future research and teaching.
Design and analysis of the covert channel implemented by behaviors of network users

In this paper, a novel covert channel, called covert behavior channel, is proposed according to behaviors of network users to solve the security and efficiency problem of the traditional covert channel. In the proposed channel, operation sequences of the network protocols are used as carriers of covert information. An encryption-based information embedding scheme is designed to improve security of the covert information. With the help of Markov model, the capacity of the proposed covert channel with time-varying noise is derived. The formulation for analyzing the covert behavior channel is presented against the channel noise aroused by discarding packets. By introducing corrected entropy-based algorithm to detect the covert behavior channel, the security of the channel is verified. Numerical results show that the proposed covert behavior channel is more secure than covert storage channels and achieves a better bit rate and robustness than that of covert timing channels.

Dual-comb generation from a dual-ring hybrid mode-locked fiber laser

Dual-comb generation with bidirectional fiber ring laser is highly prospective for its compactness and coherency. In this paper, we propose a dual-ring hybrid mode-locked fiber laser for dual-comb generation. The dual-ring laser contains elements of hybrid mode-locking for each sub-ring individually, while sharing the bidirectionally pumped erbium-doped fiber (EDF). The hybrid mode-locking is realized by transmission semiconductor saturable absorber (SESA) and nonlinear polarization evolution (NPE). With the help of two three-port optical circulators, non-ideal reflection of two SESAs are eliminated. Accordingly, two series of short pules are generated in each sub-ring with different direction individually. Experimental observations and analyses demonstrate that dual comb of about 300 kHz difference in repetition rates are generated by inserting a 10 cm cavity length difference between the two sub-rings. With the help of hybrid mode-locking and large power bidirectional pumping, the mode-locking of dual combs are stable and self-starting.
