A Variable Attenuator with Flat Group Delay Characteristics for PCS Applications (1998)

A new reflective-type variable attenuator for PCS applications using a backward-wave quadrature hybrid and four PIN diodes is presented. The proposed configuration uses a single bias line for the four diodes with each two being separated by quarter wavelength transmission line. Simulation and experimental results show that an attenuation range of 14.3 dB with a maximum phase variation of 3° can easily be achieved. The attenuation and group delay exhibit good flatness with a variation of ±0.06 dB in attenuation and ±20 ps in group delay over a 100MHz bandwidth.

On-chip integrated exceptional surface microlaser (2023)

The on-chip integrated visible microlaser is a core unit of high-speed visible-light communication with huge bandwidth resources, which needs robustness against fabrication errors, compressible linewidth, reducible threshold, and in-plane emission. However, until now, it has been a great challenge to meet these requirements simultaneously. Here, we report a scalable strategy to realize a robust on-chip integrated visible microlaser with further improved lasing performances enabled by the increased orders (<i>n</i>) of exceptional surfaces, and experimentally verify the strategy by demonstrating the performances of a second-order exceptional surface-tailored microlaser. We further prove the potential application of the strategy by discussing an exceptional surface-tailored topological microlaser with unique performances. This work lays a foundation for further development of on-chip integrated high-speed visible-light communication and processing systems, provides a platform for the fundamental study of non-Hermitian photonics, and proposes a feasible method of joint research for non-Hermitian photonics with nonlinear optics and topological photonics.
A Search for Carbene−Solvent Interactions Using Time-Resolved Infrared Spectroscopy (2003)

[reaction: see text] The time-resolved infrared (TRIR) spectra of chlorophenylcarbene (CPC) and fluorophenylcarbene (FPC) were recorded in heptane at ambient temperature. The C[bond]C and C[bond]F vibrational frequencies involving the carbene carbon were obtained in heptane, benzene, and acetonitrile and in heptane containing 0.1M tetrahydrofuran or benzene. It is concluded that carbene-solvent interactions of CPC and FPC are quite weak.
Mechanistic Analysis of the C–H Amination Reaction of Menthol by CuBr2 and Selectfluor (2018)

The mechanism of the Ritter-type C-H amination reaction of menthol with acetonitrile using CuBr<sub>2</sub>, Selectfluor, and Zn(OTf)<sub>2</sub>, first disclosed by Baran and coworkers in 2012, was studied using a combination of online electrospray ionization mass spectrometry, continuous UV/vis spectrometric monitoring, and density functional theory calculations. In addition to corroborating Baran's original mechanistic proposal, these studies uncovered a second pathway to product formation, which likely only occurs in microdroplets. DFT calculations show that neither pathway has a barrier that is greater than 6.8 kcal/mol, suggesting that both mechanisms are potentially operative under ambient conditions.

Basic Principles of Solute Transport (2016)

Abstract From a kinetic perspective, Figure 4.1 depicts the relevant flows for determining CRRT clearances while Table 4.1 provides the solute clearance expressions, which differ from those used in conventional hemodialysis. In the latter therapy, the mass removal rate (i.e., the rate at which the hemodialyzer extracts solute from blood into the dialysate) is estimated by measuring the difference in solute concentration between the arterial and venous lines. In other words, a “blood-side” clearance approach is used. On the other hand, in CRRT, the mass removal rate is estimated by measuring the actual amount of solute appearing in the effluent. The mass removal rate is the product of the effluent flow rate (QEFF) and the effluent concentration of the solute (CEFF).
Flood Event Detection from Sentinel 1 and Sentinel 2 Data: Does Land Use Matter for Performance of U-Net based Flood Segmenters? (2022)

Floods are among the most costly weather hazards for societies and businesses globally. With increasing global warming, these events have become even more frequent and more devastating. Thus, accurate flood mapping has become critical for disaster relief, risk management and mitigation. Current flood segmentation methods use either threshold-based approaches or deep-learning schemes, e.g. using the U-Net architecture, to differentiate between water-covered bodies or dry land on Earth observation images. Many schemes are exploiting imagery from synthetic aperture radar (e.g. Sentinel 1 satellites) or visual bands of satellites such as the Sentinel 2, but often restrict themselves to using one or very few modalities, i.e. spectral wavelengths, despite the availability of many more wavelengths or pre-processed indices with potential value to the challenge. In support of operationalizing flood segmentation on a global scale using deep learning, we propose semantic flood segmentation exploiting optionally many different modalities (i.e. multimodal flood segmentation), making the approach largely immune to geographic differences across the globe. Using U-Net at the core of our work, we observe very good generalisation of our segmentation model to unseen flood events in our holdout set at the level of 0.95 F1 Score (0.92 IoU) for both no water and water class, and 0.53 F1 Score (0.43 IoU) for water class, respectively.
Integrated Passive Technology for Wireless Basestation Applications (2007)

An integrated passive device (IPD) technology has been developed for wireless basestations applications. The technology features 6-mil GaAs substrates, airbridges for MIM capacitors, thick gold metallization for high Q inductors, and through-wafer vias for ultra-low-loss RF grounding. Extensive EM simulations were used in the evaluation and design of the inductors, capacitors, through-wafer vias, and the bond wires connecting the LDMOS die and the IPD. 900 MHz and 2.7 GHz Class AB LDMOS power amplifiers (PAs) using IPD output impedance matching networks, and a 900 MHz Class F PA using an IPD harmonic termination circuit, have been designed, fabricated, and tested. All systems show excellent RF performances.
SAR Studies of Anti-MRSA Non-zwitterionic 3-Heteroarylthiocephems. (2000)

SAR studies in a series of 3-heteroarylthio substituted cephalosporins established that high activity against methicillin-resistant Staphylococcus aureus (MRSA) can be achieved with various heteroaryl substituents. Early results showed that highly lipophilic 3-heteroarylthio substituents, which were necessary for anti-MRSA activity, caused high affinity of such cephems toward serum proteins. Our earlier published efforts described discovery of zwitterionic cephems MC-02,331 and RWJ-54428 (MC-02,479), where serum binding was reduced by employing basic, positively charged functionalities attached to the 3-heteroarylthio substituent. In order to avoid low solubility problems associated with most such zwitterionic cephalosporins a wide variety of non-basic heteroaryl substituents was tested (non-zwitterionic cephems are more easily formulated as water soluble sodium salts for intravenous administration). Considerable reduction in serum binding was obtained in some analogs while maintaining high anti-MRSA potency.

Integrated genetic and pharmacologic interrogation of rare cancers (2016)

Identifying therapeutic targets in rare cancers remains challenging due to the paucity of established models to perform preclinical studies. As a proof-of-concept, we developed a patient-derived cancer cell line, CLF-PED-015-T, from a paediatric patient with a rare undifferentiated sarcoma. Here, we confirm that this cell line recapitulates the histology and harbours the majority of the somatic genetic alterations found in a metastatic lesion isolated at first relapse. We then perform pooled CRISPR-Cas9 and RNAi loss-of-function screens and a small-molecule screen focused on druggable cancer targets. Integrating these three complementary and orthogonal methods, we identify CDK4 and XPO1 as potential therapeutic targets in this cancer, which has no known alterations in these genes. These observations establish an approach that integrates new patient-derived models, functional genomics and chemical screens to facilitate the discovery of targets in rare cancers.
Series resonant converter for pulsating power operating at fixed frequency (2022)

This paper presents a Series Resonant Converter (SRC) isolated power supply to regulate several outputs, delivering 70kW average power pulsating from no load to several hundred kW. The design is for magnetic resonance imaging (MRI) system application. The full-bridge power stage is controlled at fixed frequency with phase-shift between the two legs. The power supply has been designed to operate on discontinuous conduction mode, keeping soft switching over the whole power range, and tolerant to inductance and capacitance spread. The control has a feedback loop for output voltage regulation and a faster loop regulating the power through the resonant tank. The design has been implemented in a protype and the paper shows test results with the pulsating power load of the system. The proposed approach provides the high performance needed for MRI. All the outputs are tightly regulated even with the large power transients and the soft switching ensures low losses for improved footprint.
Improvement of DOA Estimation by using Quaternion Output in Sound Event Localization and Detection (2019)

This paper describes improvement of Direction of Arrival (DOA) estimation performance using quaternion output in the Detection and Classification of Acoustic Scenes and Events (DCASE) 2019 Task 3. DCASE 2019 Task3 focuses on the sound event localization and detection (SELD) which is a task that simultaneously estimates the sound source direction in addition to conventional sound event detection (SED). In the baseline method, the sound source direction angle is directly regressed. However, the angle is a periodic function and it has discontinuities which may make learning unstable. Specifically, even though -180 deg and 180 deg are in the same direction, a large loss is calculated. Estimating DOA angles with a classification approach instead of regression can solve such instability of discontinuities but this causes limitation of resolution. In this paper, we propose to introduce the quaternion which is a continuous function into the output layer of the neural network instead of directly estimating the sound source direction angle. This method can be easily implemented only by changing the output of the existing neural network, and thus does not significantly increase the number of parameters in the middle layers. Experimental results show that proposed method improves the DOA estimation without significantly increasing the number of parameters.
Raman Measurements of Thermal Transport in Suspended Monolayer Graphene of Variable Sizes in Vacuum and Gaseous Environments (2010)

Using micro-Raman spectroscopy, the thermal conductivity of a graphene monolayer grown by chemical vapor deposition and suspended over holes with different diameters ranging from 2.9 to 9.7 μm was measured in vacuum, thereby eliminating errors caused by heat loss to the surrounding gas. The obtained thermal conductivity values of the suspended graphene range from (2.6 ± 0.9) to (3.1 ± 1.0) × 10(3) Wm(-1)K(-1) near 350 K without showing the sample size dependence predicted for suspended, clean, and flat graphene crystal. The lack of sample size dependence is attributed to the relatively large measurement uncertainty as well as grain boundaries, wrinkles, defects, or polymeric residue that are possibly present in the measured samples. Moreover, from Raman measurements performed in air and CO(2) gas environments near atmospheric pressure, the heat transfer coefficient for air and CO(2) was determined and found to be (2.9 +5.1/-2.9) and (1.5 +4.2/-1.5) × 10(4) Wm(-2)K(-1), respectively, when the graphene temperature was heated by the Raman laser to about 510 K.
Polysémie verbale et construction syntaxique : étude sur le verbe jouer (2003)

Dans l’analyse semantique de textes, un des obstacles au TAL est la polysemie des unites linguistiques. Par exemple, le sens du verbe jouer peut varier en fonction du contexte : Il joue de la trompette (pratiquer) ; Il joue avec son fils (s’amuser). Une des approches pour traiter ces ambiguites de sens, est le modele de la construction dynamique du sens propose par B. Victorri et C. Fuchs (1996). Dans ce modele, on associe a chaque unite polysemique un espace semantique, et le sens de l’unite dans un enonce donne est le resultat d’une interaction dynamique avec les autres unites presentes dans l’enonce. Nous voulons montrer ici que les constructions verbales sont des elements du co-texte qui contribuent, au meme titre que le co-texte lexical, au processus dynamique de construction du sens du verbe. L’objectif est alors de montrer que les constructions verbales sont porteuses de sens intrinseque (Goldberg, 1995) et qu’elles permettent dans notre modele de contraindre automatiquement le sens d’un verbe.
<title>Photonic delay lines using polarization-selective holograms for optical signal routing</title> (1998)

The use of polarization selective holograms for the implementation of photonic delay lines (PDL) is proposed. A single bit PDL using FLC devices as active polarization switches and polymer dispersed liquid crystal (PDLC) devices as polarization selective optical path routing components is experimentally demonstrated and characterized. Different within-channel leakage noise filters are discussed and experimentally demonstrated, and high signal-to-leakage noise ratios are obtained for both PDL settings.
Oxidation Behavior of Hot‐Pressed Si 3 N 4 (1975)

The high‐temperature chemical stability of hot‐pressed Si 3 N 4 was studied between 600° and 1450°C. Reactions were followed by X‐ray diffraction and scanning electron microscopy. In air, this material begins to oxidize at 700° to 750°C; a distinct amorphous siO 2 surface layer results after 24 h at 750°C‐Concomitant formation of cristobalite occurs, depending on exposure time, and is enhanced as temperature is Increased. Magnesium and calcium magnesium silicates form above 1000°C. The data suggest that impurities, e.g. Mg, Ca, and Fe, greatly lower the oxidation resistance of Si 3 N 4 in air.

Expanding the horizons of wildfire risk management (2014)

Owing to increased computational capacity and other factors, wildfire simulation methodologies are becoming increasingly sophisticated, and are subsequently seeing increasing use for federal fire management within the United States. State-of-the-art simulation systems account for the occurrence, topological spread, and behaviour of wildfire, all within a spatially-explicit, stochastic framework. Leveraging these advancements in burn probability modelling, researchers and managers alike are better able to assess the hazards and risks associated with wildfires and to identify effective and efficient risk mitigation opportunities. In this paper, we review the role of stochastic simulation modelling in wildfire risk assessment, focusing on how simulation results can be used to support risk-informed decision making across planning contexts. Our principal focus will be describing how novel assessment tools can be brought to bear to analyse risks to the wildland urban interface and to municipal water supplies. We will review how assessment results can inform high-level prioritization and allocation decisions, as well as more in-depth, spatial suppression response and fuel treatment planning.
Diamond‐Gardner Syndrome: A Case Report (1998)

Abstract: We present a 13‐year‐old girl who came to our attention for an erythematous bruised lesion which appeared spontaneously without any apparent coagulopathy. The history, histology, and positive “skintest,” carried out by subcutaneously injecting autologous erythrocytes obtained from heparinized blood, confirmed the suspected diagnosis of Diamond‐Gardner syndrome. No alterations of blood vessel walls or thromboses were found. Evaluation of hemocoagulative parameters revealed an increased factor VIII level and reduced platelet aggregation after stimulation by adenosine diphosphate (ADP.)
Fast Bayesian Force Fields from Active Learning: Study of Inter-Dimensional Transformation of Stanene (2020)

Gaussian process (GP) regression is one promising technique of constructing machine learning force fields with built-in uncertainty quantification, which can be used to monitor the quality of model predictions. A current limitation of existing GP force fields is that the prediction cost grows linearly with the size of the training data set, making accurate GP predictions slow. In this work, we exploit the special structure of the kernel function to construct a mapping of the trained Gaussian process model, including both forces and their uncertainty predictions, onto spline functions of low-dimensional structural features. This method is incorporated in the Bayesian active learning workflow for training of Bayesian force fields. To demonstrate the capabilities of this method, we construct a force field for stanene and perform large scale dynamics simulation of its structural evolution. We provide a fully open-source implementation of our method, as well as the training and testing examples with the stanene dataset.
Optimal interference of the tibial component of the cementless Oxford Unicompartmental Knee Replacement (2018)

This study suggests that decreasing the interference fit of the tibial component of the cementless OUKR reduces the push-in force and can increase the pull-out force. An optimal interference fit may both improve primary fixation and decrease the risk of fracture.<b>Cite this article</b>: S. Campi, S. J. Mellon, D. Ridley, B. Foulke, C. A. F. Dodd, H. G. Pandit, D.

Genome-wide methylation analyses of primary human leukocyte subsets identifies functionally important cell-type–specific hypomethylated regions (2013)

DNA methylation is an important mechanism by which gene transcription and hence cellular function are regulated. Here, we provide detailed functional genome-wide methylome maps of 5 primary peripheral blood leukocyte subsets including T cells, B cells, monocytes/macrophages, and neutrophils obtained from healthy individuals. A comparison of these methylomes revealed highly specific cell-lineage and cell-subset methylation profiles. DNA hypomethylation is known to be permissive for gene expression and we identified cell-subset-specific hypomethylated regions (HMRs) that strongly correlate with gene transcription levels suggesting these HMRs may regulate corresponding cell functions. Single-nucleotide polymorphisms associated with immune-mediated disease in genome-wide association studies preferentially localized to these cell-specific regulatory HMRs, offering insight into pathogenesis by highlighting cell subsets in which specific epigenetic changes may drive disease. Our data provide a valuable reference tool for researchers aiming to investigate the role of DNA methylation in regulating primary leukocyte function in health and immune-mediated disease.
