[Quantification of left ventricular function by subtraction intravenous angiography]. (1985)

Digitised intravenous angiography (Diva), initially applied to the study of the aorta and great vessels, has benefited from technical advances, especially the possibility of recording 25 frames per second, which now allows studies of the heart itself. 22 subjects underwent angiography with digitised subtraction after injection of 50 ml of sodium diatrizoate and meglumine in the right atrium and selective left ventriculography in the same catheter session. The end diastolic and systolic indices and global ejection fractions were measured independently for each technique by Chapman's method by two observers. The model of digitised angiography used was a CGR Divas prototype functioning in the pulsed graphic mode at 25 images per second. The results showed that the Diva method gave reproducible values of the end diastolic index (101 +/- 29.8 and 104.5 +/- 30.7: r = 0.98), of the end systolic index (43.2 +/- 32.9 and 44.6 +/- 32.5; r = 0.98), and of the ejection fraction (62.5 +/- 17.16 p. 100 and 62.17 +/- 15.7 p. 100; r = 0.96). There was a close correlation between the results of Diva and selective ventriculography (end diastolic index: 97.8 +/- 21.1 and 101.6 +/- 10.3; r = 0.87; end systolic index: 38.82 +/- 24.8 and 43.9 +/- 21.17; r = 0.95; ejection fraction: 62.12 +/- 16.27 and 57.29 +/- 15.53; r = 0.95). There was a significant underestimation of the end systolic index using Diva (0.01 less than p less than 0.02). The originality of the pulsed graphic method is the totally digitised character of the data.(ABSTRACT TRUNCATED AT 250 WORDS)
Deep-ultraviolet transparent conductive β-Ga2O3 thin films (2000)

Thin films of β-Ga2O3 with an energy band gap of 4.9 eV were prepared on silica glass substrates by a pulsed-laser deposition method. N-type conductivity up to ∼1 S cm−1 was obtained by Sn-ion doping and deposition under low O2 partial pressure (∼10−5 Pa) at substrate temperatures above 800 °C. The resulting internal transmittance at the wavelength (248 nm) of the KrF excimer laser exceeded 50% for the 100-nm-thick film, making this the most ultraviolet-transparent conductive oxide thin film to date and opening up prospects for applications such as ultraviolet transparent antistatic electric films in ultraviolet lithography.
Failure to Find Sodium Pregnanediol Glucuronidate in Bull's Urine (1941)

No sodium pregnanediol glucuronidate was found in urine obtained from the bladders of slaughtered bulls and steers by the method of Venning. The volumes of urine were judged sufficient for demonstration of this substance if it were present in the amount suggested by Marker's results for pregnanediol 3a, 20a from hydrolyzed bull's urine.
Structural, Morphological, Optical, and Magnetic Properties of Fe-Doped CuO Nanostructures (2014)

Pure and Fe-doped CuO nanostructures with different weight ratios (0.5, 1.0, 1.5, and 2.0 at wt% of Fe) were prepared by a facile and fast microwave combustion method. The structure and morphology of the samples were investigated by X-ray diffraction (XRD), high resolution scanning electron microscopy (HR-SEM), diffuse reflectance spectroscopy (DRS), photoluminescence (PL) spectroscopy and vibrating sample magnetometry (VSM). The XRD patterns refined by the Rietveld method indicated the formation of single-phase monoclinic structure and also confirm that the Fe ions are successfully incorporated into the CuO crystal lattice by occupying Cu ionic sites. Interestingly, the morphology was found to change considerably from nanoflowers to nanorod and disk-shaped then to nanoparticles with the variation of Fe content. The optical band gap calculated using DRS was found to be 2.8 eV for pure CuO and increases up to 3.4 eV with increasing Fe content. Photoluminescence measurements also confirm these results. The magnetic measurements indicated that the obtained nanostructures are found to show a room temperature ferromagnetism (RTF) with an optimum value of saturation magnetization at 2.0 wt.% of Fe-doped CuO, i.e.1.2960 x 10 -3 emu/g.
Recognition-Based Approach of Numeral Extraction in Handwritten Chemistry Documents Using Contextual Knowledge (2016)

This paper presents a complete procedure that uses contextual and syntactic information to identify and recognize amount fields in the table regions of chemistry documents. The proposed method is composed of two main modules. Firstly, a structural analysis based on connected component (CC) dimensions and positions identifies some special symbols and clusters other CCs into three groups: fragment of characters, isolated characters or connected characters. Then, a specific processing is performed on each group of CCs. The fragment of characters are merged with the nearest character or string using geometric relationship based rules. The characters are sent to a recognition module to identify the numeral components. For the connected characters, the final decision on the string nature (numeric or non-numeric) is made based on a global score computed on the full string using the height regularity property and the recognition probabilities of its segmented fragments. Finally, a simple syntactic verification at table row level is conducted in order to correct eventual errors. The experimental tests are carried out on real-world chemistry documents provided by our industrial partner eNovalys. The obtained results show the effectiveness of the proposed system in extracting amount fields.
Evidence for a copper‐coordinated histidine–tyrosine cross‐link in the active site of cytochrome oxidase (1999)

Following hints from X-ray data (Ostermeier C et al., 1997, Proc Natl Acad Sci USA 94:10547-10553; Yoshikawa S et al., 1998, Science 280: 1723-1729), chemical evidence is presented from four distantly related cytochrome-c oxidases for the existence of a copperB-coordinated His240-Tyr244) cross-link at the O2-activating Heme Fea3-CuB center in the catalytic subunit 1 of the enzyme. The early evolutionary invention of this unusual structure may have prevented damaging *OH-radical release at e(-)-transfer to dioxygen and thus have enabled O2 respiration.
Changes in voiding behavior in a mouse model of Alzheimer’s disease (2015)

Besides cognitive decline and behavioral alteration, urinary incontinence often occurs in patients suffering from Alzheimer's disease (AD). To determine whether the transgenic mouse model of AD, APP/PS1 (APP(SL)/PS1(M146L)) mouse, shows alteration of the urinary bladder function and anxiety, as for patients with AD, we examined the urinary marking behavior in relation to affective behavior. At 18 months of age voiding behavior of APP/PS1 and wild type (WT) mice was assessed by using a modified filter paper assay in combination with video tracing, with the cage divided into a center and corner zones. Anxiety-related behavior and locomotion were respectively tested in an elevated zero maze (EZM) and an open field (OF). The APP/PS1 mice urinated more in the center zone than the WT mice. The total volume of markings was significantly lower in the APP/PS1 mice. In both groups, the average volume of a marking in the corner zone was larger than in the center zone. In the EZM, the APP/PS1 mice spent less time in the open arms of the arena, considered as anxiogenic zones, than the WT mice. During the OF task, the APP/PS1 mice covered a longer distance than the WT mice. These findings show that the APP/PS1 mice have a different voiding behavior compared to the WT mice, i.e., urinating with small volumes and voiding in the center of the cage, and suggest that increased locomotor activity and anxiety-related behaviors are factors in the change in voiding pattern in the APP/PS1 mouse.

Determining Accelerated Charging Procedure from Half Cell Characterization (2019)

For implementation and consumer acceptance of electric vehicles, it is critical that the convenience of fueling internal combustion engines will not be lost for a transition to electric vehicles to be made. Although this complex issue involves many facets, ranging from recharging station infrastructure to technology development, one key component is "refueling" in a short period of time. Possible solutions would be battery replacement or recharge time comparable to that of filling a gas tank. This study provides an investigation for the development of an accelerated full-cell charge procedure through an investigation and characterization of half-cell performance. Negative and positive half-cell polarization curves at various rates were used to determine the maximum rate for each step of the lithiation process. This analysis was then applied to the LiNi1/3Mn1/3Co1/3O2 (NMC)/graphite full cells, charging cells to 80% state of charge in ∼34 minutes and showing capacity fade over 75 cycles similar to cells cycled using conventional constant-current-constant-voltage (CCCV) charge procedure.
RF Systems Design for Simultaneous Wireless Information and Power Transfer (SWIPT) in Automation and Transportation (2021)

This work presents some recent solutions that exploit the wireless power transfer (WPT) technology for energizing moving vehicles and machinery tools. Such technology is currently experiencing unprecedented interests in non-traditional RF/microwave sectors fields, such the industrial automation and the railway transportation safety. Near-field electromagnetic coupling solutions are presented showing that, in order to obtain efficient performances for broad ranges of operating conditions, the nonlinear electromagnetic co-design of the entire WPT system, from the energy source to the receiver load, needs to be carried out. This technology can be combined with wireless data transfer, thus realizing integrated systems able to simultaneously control the energy transfer and the transmission of data. The adopted operating frequencies are in the MHz range, which is only recently considered for this kind of applications. In particular this work focuses on three different systems: the first one demonstrates the constant powering of “on the move” industrial charts at 6.78 MHz, regardless of the relative position of the transmitter and the receiver sub-systems; the second one presents a novel design of a balise transportation system adopting a high efficiency GaN-based transmitter designed to keep its performance over a wide range of loading conditions; the last one consists of the simultaneous wireless power and data transfer, to a rotating machinery tool, automatically controlled by the powering system based on the coexistence of frequency-diverse inductive and capacitive couplings.

Gulf of Mexico Hurricane Glider Operations in Support of Tropical Cyclone Intensification Forecasts (2020)

During the 2019 peak hurricane season, two gliders operated by Texas A&M University (TAMU) and the University of Southern Mississippi (USM) and funded by Shell Exploration & Production Company were deployed as part of the National Oceanic and Atmospheric Administration Hurricane Glider Program to collect near-real time subsurface ocean temperature and salinity measurements for data assimilation into global ocean and hurricane models. The missions were designed to resolve regional ocean features that can contribute to hurricane intensity and provide spatial coverage in the event of a tropical cyclone with the intent to capture potential intensification prior to landfall. For the Gulf of Mexico, the Mississippi River plume, Loop Current, and Loop Current Eddies are areas of interest that can contribute to hurricane intensity. Tropical Storms Nester and Olga were named storms during the 2019 season in the Atlantic Basin, and their trajectories passed by the USM and TAMU gliders, respectively. While changes in the sea surface temperature were more likely due to the presence of seasonal fronts rather than the passing of these tropical storms, the data did indicate pockets of subsurface warm water under a freshwater plume from the Mississippi River. Currently, multiple hurricane glider missions are underway in the Gulf of Mexico during a record breaking 2020 season with Hurricane Laura anticipated to make landfall early morning (local time) on Thursday, August 27, 2020 near the Texas/Louisiana border.
Synthetic and Enhanced Index Strategies Using Futures on U.S. Indexes (1999)

Stock index futures and swaps offer a means of generating index return that is flexible and efficient from both a cost and an operational perspective. Index replication strategies include equitizing cash, tightening benchmark tracking, enhancing index returns, synthetic international indexing, global asset allocation, synthetic indexing as part of a strategy or manager transition, and country or capitalization tilts. This article provides a detailed analysis of the basic building blocks common to all these strategies. Using the most common futures on U.S. indexes, they show how synthetic index returns are generated and analyze their performance and tracking risk characteristic. The evidence is that, because of reversals in monthly synthetic returns compared to indexes, quarterly return tracking error is much lower and a better indication of tracking risk than that based on monthly return.
Towards Low-Latency Byzantine Agreement Protocols Using RDMA (2018)

Byzantine fault tolerance (BFT) protocols can mitigate attacks and errors and are increasingly investigated as consensus protocols in blockchains. However, they are traditionally considered costly in terms of message complexity and latency due to the required multiple rounds of message exchanges. With the availability of Remote Direct Memory Access (RDMA) in data centers, message exchange latency can be reduced compared to TCP, as RDMA enables kernel bypassing and thereby avoids intermediate data copying. Retaining the performance benefits for RDMA during its integration, however, is non-trivial and error-prone. While the use of RDMA has previously been explored for key/value stores, databases and distributed file systems, agreement protocols especially for BFT have so far been neglected. We investigate the usage of RDMA in the Reptor BFT protocol for low-latency agreement and show first steps towards an RDMA-enabled consensus protocol. For this, we present Rubin, a framework offering similar functionality to the Java NIO selector, which can handle multiple network connections efficiently with a single thread and is employed in several BFT protocol implementations such as BFT-SMaRt and UpRight.
Using a Declarative Language to Describe the Interactions in Virtual Scenes (2006)

A generic platform useful to design and run virtual scenes as a result of a human-like description is introduced. The present article describes the operation of one of the main components of such platform: the virtual-environment (VE) editor. The main goal of the VE editor is to allow a human description of a virtual scene and translate it, if errors-free, into a set of low-level commands. The modeler is provided a declarative language useful to: a) arrange the virtual entities using geometric constraints instead of geometrical data, b) assign personalities to virtual humans, and c) specify goals to be fulfilled by virtual humans. A scene takes place in a specific world. For every different world to model a set of rules must be defined. The VE editor allows the specification of some features related to a particular virtual world, including the following: actions and skills that can be performed, virtual entities acceptable, pre-and post- conditions for interactions, effect of natural laws (gravity, collisions), and a set of rules, which reject or allow the assignment of goals according to the state of virtual humans
Model Checking with Program Slicing Based on Variable Dependence Graphs (2012)

In embedded control systems, the potential risks of software defects have been increasing because of software complexity which leads to, for example, timing related problems. These defects are rarely found by tests or simulations. To detect such defects, we propose a modeling method which can generate software models for model checking with a program slicing technique based on a variable dependence graph. We have applied the proposed method to one case in automotive control software and demonstrated the effectiveness of the method. Furthermore, we developed a software tool to automate model generation and achieved a 35% decrease in total verification time on model checking.
Patient-specific mutations impair BESTROPHIN1’s essential role in mediating Ca2+-dependent Cl- currents in human RPE (2017)

Mutations in the human <i>BEST1</i> gene lead to retinal degenerative diseases displaying progressive vision loss and even blindness. BESTROPHIN1, encoded by <i>BEST1</i>, is predominantly expressed in retinal pigment epithelium (RPE), but its physiological role has been a mystery for the last two decades. Using a patient-specific iPSC-based disease model and interdisciplinary approaches, we comprehensively analyzed two distinct <i>BEST1</i> patient mutations, and discovered mechanistic correlations between patient clinical phenotypes, electrophysiology in their RPEs, and the structure and function of BESTROPHIN1 mutant channels. Our results revealed that the disease-causing mechanism of <i>BEST1</i> mutations is centered on the indispensable role of BESTROPHIN1 in mediating the long speculated Ca<sup>2+</sup>-dependent Cl<sup>-</sup> current in RPE, and demonstrate that the pathological potential of <i>BEST1</i> mutations can be evaluated and predicted with our iPSC-based 'disease-in-a-dish' approach. Moreover, we demonstrated that patient RPE is rescuable with viral gene supplementation, providing a proof-of-concept for curing <i>BEST1</i>-associated diseases.
Outcomes in Patients With Metastatic Renal Cell Carcinoma Who Develop Everolimus-Related Hyperglycemia and Hypercholesterolemia: Combined Subgroup Analyses of the RECORD-1 and REACT Trials (2016)

Hyperglycemia and hypercholesterolemia were observed in low numbers of patients, and although these events might be associated with improved response to everolimus, the differences were not significant. These findings should be validated with prospective biomarker studies.
Recent advances in the modified chemical vapor deposition (MCVD) process (1983)

The MCVD process is shown in Figure 1. Owing to its simplicity, versatility and flexibility, it has become the most widely implemented fabrication technique for making high performance multimode and single mode lightguides with optimized optical, mechanical and dimensional performance. Figure 2 shows a schematic of the preform apparatus. This paper highlights key advances in MCVD technology, process rate and performance.
Limitations of toxicity characterization in life cycle assessment: Can adverse outcome pathways provide a new foundation? (2015)

Life cycle assessment (LCA) has considerable merit for holistic evaluation of product planning, development, production, and disposal, with the inherent benefit of providing a forecast of potential health and environmental impacts. However, a technical review of current life cycle impact assessment (LCIA) methods revealed limitations within the biological effects assessment protocols, including: simplistic assessment approaches and models; an inability to integrate emerging types of toxicity data; a reliance on linear impact assessment models; a lack of methods to mitigate uncertainty; and no explicit consideration of effects in species of concern. The purpose of the current study is to demonstrate that a new concept in toxicological and regulatory assessment, the adverse outcome pathway (AOP), has many useful attributes of potential use to ameliorate many of these problems, to expand data utility and model robustness, and to enable more accurate and defensible biological effects assessments within LCIA. Background, context, and examples have been provided to demonstrate these potential benefits. We additionally propose that these benefits can be most effectively realized through development of quantitative AOPs (qAOPs) crafted to meet the needs of the LCIA framework. As a means to stimulate qAOP research and development in support of LCIA, we propose 3 conceptual classes of qAOP, each with unique inherent attributes for supporting LCIA: 1) mechanistic, including computational toxicology models; 2) probabilistic, including Bayesian networks and supervised machine learning models; and 3) weight of evidence, including models built using decision-analytic methods. Overall, we have highlighted a number of potential applications of qAOPs that can refine and add value to LCIA. As the AOP concept and support framework matures, we see the potential for qAOPs to serve a foundational role for next-generation effects characterization within LCIA.

A utilization bound for aperiodic tasks and priority driven scheduling (2004)

Real-time scheduling theory offers constant-time schedulability tests for periodic and sporadic tasks based on utilization bounds. Unfortunately, the periodicity or the minimal interarrival-time assumptions underlying these bounds make them inapplicable to a vast range of aperiodic workloads such as those seen by network routers, Web servers, and event-driven systems. This paper makes several important contributions toward real-time scheduling theory and schedulability analysis. We derive the first known bound for schedulability of aperiodic tasks. The bound is based on a utilization-like metric we call synthetic utilization, which allows implementing constant-time schedulability tests at admission control time. We prove that the synthetic utilization bound for deadline-monotonic scheduling of aperiodic tasks is 1/1+/spl radic/1/2. We also show that no other time-independent scheduling policy can have a higher schedulability bound. Similarly, we show that EDF has a bound of 1 and that no dynamic-priority policy has a higher bound. We assess the performance of the derived bound and conclude that it is very efficient in hit-ratio maximization.
