Wavefront Array Processor: Language, Architecture, and Applications (1982)

This paper describes the development of a wavefront-based language and architecture for a programmable special-purpose multiprocessor array. Based on the notion of computational wavefront, the hardware of the processor array is designed to provide a computing medium that preserves the key properties of the wavefront. In conjunction, a wavefront language (MDFL) is introduced that drastically reduces the complexity of the description of parallel algorithms and simulates the wavefront propagation across the computing network. Together, the hardware and the language lead to a programmable wavefront array processor (WAP). The WAP blends the advantages of the dedicated systolic array and the general-purpose data-flow machine, and provides a powerful tool for the high-speed execution of a large class of matrix operations and related algorithms which have widespread applications.
Rotorcraft convertible engine study (1983)

Convertible propulsion systems for advanced rotorcraft are evaluated in terms of their impact on aircraft operating economics and fuel consumption. A variety of propulsion system concepts, including separate thrust and power producing engines, convertible fan/shaft engines, and auxiliary propeller configurations are presented. The merits of each are evaluated in two different rotorcraft missions: an intercity, commercial transport of the ABC(TM) type, and an offshore oil ring supply ship of the X-wing type. The variable inlet guide vane fan/shaft converting engine and auxiliary propeller configurations are shown to offer significant advantages over all the other systems evaluated, in terms of both direct operating cost and fuel consumption.
15.1 An 88%-Efficiency Supply Modulator Achieving 1.08μs/V Fast Transition and 100MHz Envelope-Tracking Bandwidth for 5G New Radio RF Power Amplifier (2019)

In the recent 3GPP standard, 5G New Radio (NR) in the sub-6GHz frequency band supports up to 100MHz bandwidth (BW) for uplink channel and requires fast on/off transition below $10 \mu \mathrm {s}$ to support short transition-time interval (TTI). Thus, it forces the supply modulator (SM) to track the NR-100MHz envelope signal for power saving of an RF power amplifier (RF-PA) and requires a fast dynamic voltage-scaling (DVS) transition. For the 3G/LTE uplink, the SM has to satisfy low receiver-band noise (RxBN) for LTE-FDD bands [1] and a boosted output for Power Class 2 high-power user equipment (HPUE) in TD-LTE [2], [3]. In order to support the 100MHz envelope tracking (ET) BW, the SM must have a 3dB bandwidth of at least 125MHz while keeping sufficient phase margin in the presence of few-hundred-pF load capacitance. Furthermore, a typical linear-assisted SM topology has maximum efficiency limitation due to the AB bias current, sinking- and sourcing-current of the linear amplifier. In this work, a voltage-buffer-compensated (VBC) Class-AB linear amplifier (LA) and a feed-forward fast-switching (FFFS) buck converter are proposed to achieve the 100MHz ET BW and high system-power efficiency.
Oxygen Tension and Formation of Cervical-Like Tissue in Two-Dimensional and Three-Dimensional Culture (2011)

Cervical dysfunction contributes to a significant number of preterm births and is a common cause of morbidity and mortality in newborn infants. Cervical dysfunction is related to weakened load bearing properties of the collagen-rich cervical stroma. However, the mechanisms responsible for cervical collagen changes during pregnancy are not well defined. It is known that blood flow and oxygen tension significantly increase in reproductive tissues during pregnancy. To examine the effect of oxygen tension, a key mediator of tissue homeostasis, on the formation of cervical-like tissue in vitro, we grew primary human cervical cells in both two-dimensional (2D) and three-dimensional (3D) culture systems at 5% and 20% oxygen. Immunofluorescence studies revealed a stable fibroblast phenotype across six passages in all subjects studied (n=5). In 2D culture for 2 weeks, 20% oxygen was associated with significantly increased collagen gene expression (p<0.01), increased tissue wet weight (p<0.01), and increased collagen concentration (p=0.046). 3D cultures could be followed for significantly longer time frames than 2D cultures (12 weeks vs. 2 weeks). In contrast to 2D cultures, 20% oxygen in 3D cultures was associated with decreased collagen concentration (p<0.01) and unchanged collagen gene expression, which is similar to cervical collagen changes seen during pregnancy. We infer that 3D culture is more relevant for studying cervical collagen changes in vitro. The data suggest that increased oxygen tension may be related to significant cervical collagen changes seen in pregnancy.

A Practical Calendaring System Conforming with Ambiguous Pattern of Recurring Tasks (2011)

In a typical office, there are many recurring tasks. If the recurrence pattern can be determined, then this pattern can be used to forecast which task might occur or provide guidance for a coworker who takes on the given responsibilities. A calendaring system is a popular tool for task enumeration. However, the existing major implementations are not capable of handling fluctuation cycle in the recurrences or the relationships between the tasks, and thus these systems do not give the user any analytical perspective on the tasks. Therefore, this paper proposes a new calendaring system that can handle changes in the recurrences and display the relationships between tasks. Three new concepts, Task, Mission, and Job are introduced to describe the relationships between the tasks. Interoperability with the existing systems is also described.
Rapid Prototyping of Thermoset Polyester Microfluidic Devices (2004)

This paper presents a simple procedure for the fabrication of thermoset polyester (TPE) microfluidic systems and discusses the properties of the final devices. TPE chips are fabricated in less than 3 h by casting TPE resin directly on a lithographically patterned (SU-8) silicon master. Thorough curing of the devices is obtained through the combined use of ultraviolet light and heat, as both an ultraviolet and a thermal initiator are employed in the resin mixture. Features on the order of micrometers and greater are routinely reproduced using the presented procedure, including complex designs and multilayer features. The surface of TPE was characterized using contact angle measurements and X-ray photoelectron spectroscopy (XPS). Following oxygen plasma treatment, the hydrophilicity of the surface of TPE increases (determined by contact angle measurements) and the proportion of oxygen-containing functional groups also increases (determined by XPS), which indicates a correlated increase in the charge density on the surface. Native TPE microchannels support electroosmotic flow (EOF) toward the cathode, with an average electroosmotic mobility of 1.3 x 10(-4) cm(2) V(-1) s(-1) for a 50-microm square channel (20 mM borate at pH 9); following plasma treatment (5 min at 30 W and 0.3 mbar), EOF is enhanced by a factor of 2. This enhancement of the EOF from plasma treatment is stable for days, with no significant decrease noted during the 5-day period that we monitored. Using plasma-treated TPE microchannels, we demonstrate the separation of a mixture of fluorescein-tagged amino acids (glycine, glutamic acid, aspartic acid). TPE devices are up to 90% transparent (for approximately 2-mm-thick sample) to visible light (400-800 nm). The compatibility of TPE with a wide range of solvents was tested over a 24-h period, and the material performed well with acids, bases, alcohols, cyclohexane, n-heptane, and toluene but not with chlorinated solvents (dichloromethane, chloroform).
Efficient Garbling from a Fixed-Key Blockcipher (2013)

We advocate schemes based on fixed-key AES as the best route to highly efficient circuit-garbling. We provide such schemes making only one AES call per garbled-gate evaluation. On the theoretical side, we justify the security of these methods in the random-permutation model, where parties have access to a public random permutation. On the practical side, we provide the Just Garble system, which implements our schemes. Just Garble evaluates moderate-sized garbled-circuits at an amortized cost of 23.2 cycles per gate (7.25 nsec), far faster than any prior reported results.
7‐(4,6‐Dimethoxypyrimidinyl)oxy‐ and ‐thiophthalides as novel herbicides: Part 1. CGA 279 233: a new grass‐killer for rice (2001)

A series of novel types of 7-(4,6-dimethoxypyrimidin-2-yl)oxy - and -thio-3-methyl-1 (3H)-isobenzofuranones were discovered at Dr R Maag AG. From the thio-isobenzofuranyl series, CGA 279 233—BSI-proposed common name pyriftalid—was chosen for further development as a grass herbicide for use in rice. General synthetic approaches to these new phthalic acid-derived compounds are given, with emphasis on the synthesis of pyriftalid and its physico-chemical behaviour. © 2001 Society of Chemical Industry
Using BGP to Bind MPLS Labels to Address Prefixes (2017)

This document specifies a set of procedures for using BGP to advertise
that a specified router has bound a specified MPLS label (or a
specified sequence of MPLS labels organized as a contiguous part of a
label stack) to a specified address prefix. This can be done by
sending a BGP UPDATE message whose Network Layer Reachability
Information field contains both the prefix and the MPLS label(s) and
whose Next Hop field identifies the node at which said prefix is bound
to said label(s). This document obsoletes RFC 3107.

Diagnosis and Management of the Postpericardiotomy Syndrome (2014)

The present review is aimed at the presentation of recent updates on the diagnosis, management, and prevention of the postpericardiotomy syndrome (PPS) according to more recent publications in the last 24 months. Potentially relevant studies published were searched in BioMedCentral, the Cochrane Collaboration Database of Randomised Trials, ClinicalTrials.gov, EMBASE, Google Scholar, MEDLINE/PubMed, and Scopus. The PPS is a complication of cardiac and thoracic surgery that affects 10% to 40% of patients. The etiopathogenesis is incompletely understood and it is supposed to be immune mediated following pleuropericardial trauma and bleeding. There are no standardized criteria for the diagnosis although a combination of clinical criteria have been proposed in clinical trials for PPS prevention and include fever without alternative causes, pericardial or pleuritic chest pain, pericardial or pleural rubs, and pericardial and/or pleural effusion. Treatment is empiric and based on aspirin, nonsteroidal anti-inflammatory drugs, and/or corticosteroids plus colchicine. Prevention of the PPS has been demonstrated possible and safe with the use of colchicine for 1 month. Although PPS may be responsible for a prolongation of hospital stay and readmissions, the overall prognosis is generally good with low risk of recurrences and cardiac tamponade. The risk of developing constrictive pericarditis has been reported in 2% to 3% of cases in a long-term follow-up. PPS is a common postoperative complication, generally occurring in the first 3 months after surgery. Severe complications are not common, but the syndrome is responsible for hospital stay prolongation and readmissions.
Atrial Fibrillation Classification with Smart Wearables Using Short-Term Heart Rate Variability and Deep Convolutional Neural Networks (2021)

Atrial fibrillation (AF) is a type of cardiac arrhythmia affecting millions of people every year. This disease increases the likelihood of strokes, heart failure, and even death. While dedicated medical-grade electrocardiogram (ECG) devices can enable gold-standard analysis, these devices are expensive and require clinical settings. Recent advances in the capabilities of general-purpose smartphones and wearable technology equipped with photoplethysmography (PPG) sensors increase diagnostic accessibility for most populations. This work aims to develop a single model that can generalize AF classification across the modalities of ECG and PPG with a unified knowledge representation. This is enabled by approximating the transformation of signals obtained from low-cost wearable PPG sensors in terms of Pulse Rate Variability (PRV) to temporal Heart Rate Variability (HRV) features extracted from medical-grade ECG. This paper proposes a one-dimensional deep convolutional neural network that uses HRV-derived features for classifying 30-s heart rhythms as normal sinus rhythm or atrial fibrillation from both ECG and PPG-based sensors. The model is trained with three MIT-BIH ECG databases and is assessed on a dataset of unseen PPG signals acquired from wrist-worn wearable devices through transfer learning. The model achieved the aggregate binary classification performance measures of accuracy: 95.50%, sensitivity: 94.50%, and specificity: 96.00% across a five-fold cross-validation strategy on the ECG datasets. It also achieved 95.10% accuracy, 94.60% sensitivity, 95.20% specificity on an unseen PPG dataset. The results show considerable promise towards seamless adaptation of gold-standard ECG trained models for non-ambulatory AF detection with consumer wearable devices through HRV-based knowledge transfer.
Swine Manure Nitrogen Conservation in Storage using Sphagnum Moss (1995)

Abstract Sphagnum peat moss, floating on swine manure in storage, was tested during three summers as an N conservation method in experimental tanks which measured 0.75 m in diameter and 3.0 m deep. Three depths of floating peat moss (0, 10, and 20 cm) were tested. The swine manure was analyzed prior to the tests and after 14 wk of storage, from June to mid‐September. An average of 54, 60, and 76% total N conservation was observed for the respective treatments. Twenty centimeters of peat moss significantly reduced manure N losses and manure evaporation during storage.
New Real-Time PCR-Based Method for <i>Kingella kingae</i> DNA Detection: Application to Samples Collected from 89 Children with Acute Arthritis (2009)

Inoculation of blood culture vials with joint fluid samples has revealed the important pathogenic role of Kingella kingae in pediatric arthritis. However, recent studies based on broad-range 16S ribosomal DNA PCR and real-time PCR without a probe suggest that conventional methods remain suboptimal. We developed a new real-time PCR method with a probe that is highly specific for K. kingae and applied it to joint fluid samples collected from 89 children with suspected arthritis admitted to our institution during a 2-year period. Real-time PCR was also applied to blood samples obtained before surgery and to joint drainage fluid samples obtained during several days after surgery. Thirty-six (40%) of the 89 cases of suspected septic arthritis had positive culture. Staphylococcus aureus was the main isolate (n = 19/36, 53%), followed by K. kingae (n = 7/36, 19%). Specific real-time PCR identified K. kingae in 24 of the 53 culture-negative cases. Thus, K. kingae was present in 31 (52%) of the 60 documented cases, making it the leading pathogen. Real-time PCR on all 15 blood DNA extracts from patients with K. kingae infection was negative, demonstrating that joint fluid positivity did not result from DNA circulating in blood. Real-time PCR amplification of drainage fluid samples showed that the pathogen could be detected for up to 6 days after antibiotic initiation. K. kingae real-time PCR applied to DNA extracted from joint fluid samples, but not from blood samples, markedly improved the etiological diagnosis of septic arthritis in children. Retrospective diagnosis is feasible for up to 6 days after treatment initiation.
Hybrid infrared and visible light projection for location tracking (2007)

A number of projects within the computer graphics, computer vision, and human-computer interaction communities have recognized the value of using projected structured light patterns for the purposes of doing range finding, location dependent data delivery, projector adaptation, or object discovery and tracking. However, most of the work exploring these concepts has relied on visible structured light patterns resulting in a caustic visual experience. In this work, we present the first design and implementation of a high-resolution, scalable, general purpose invisible near-infrared projector that can be manufactured in a practical manner. This approach is compatible with simultaneous visible light projection and integrates well with future Digital Light Processing (DLP) projector designs -- the most common type of projectors today. By unifying both the visible and non-visible pattern projection into a single device, we can greatly simply the implementation and execution of interactive projection systems. Additionally, we can inherently provide location discovery and tracking capabilities that are unattainable using other approaches.
Exercise rehabilitation after myocardial infarction. (1977)

Exercise is beneficial to most patients with coronary heart disease. Ideally, training should be monitored but, when this is not possible, training pulse rates should be kept below 70 to 85 percent of the maximum heart rate and the patient should understand the concepts and complications of exercise training.
Nonenzymatic RNA Ligation in Water (2008)

We describe the nonenzymatic ligation of RNA oligomers in water. Dimers and tetramers are formed in a time-, pH-, and temperature-dependent reaction. Ligation efficiency depends on oligonucleotide length and sequence and is strongly enhanced by adenine-based nucleotide cofactors. Ligation of short RNA fragments could have liberated the prebiotic polymerization systems from the thermodynamically demanding task of reaching a (pre)genetically meaningful size by stepwise addition of one precursor monomer at the time.
Submicron gate Si<sub>3</sub>N<sub>4</sub>/AlGaN/GaN-metal-insulator-semiconductor heterostructure field-effect transistors (2003)

We present the characteristics of a quarter-micron gate metal-insulator-semiconductor heterostructure field-effect transistor (MISHFET) with Si/sub 3/N/sub 4/ film as a gate insulator. A detailed comparison of the MISHFET and an identical geometry HFET shows them to have the same radio frequency (RF) power gain and cut-off frequency, while the MISHFET has much lower gate-leakage currents and higher RF powers at operating frequencies as high as 26 GHz. The MISHFET gate-leakage currents are well below 100 pA at gate bias values from -10 V to +8 V. At zero gate bias, the drain saturation current is about 0.9 A/mm and it increases to 1.2 A/mm at +8 V gate bias. The output RF power of around 6 W/mm at 40 drain bias was found to be frequency independent in the range of 2 to 26 GHz. This power is 3 dB higher than that from HFET of the same geometry. The intrinsic cutoff frequency is /spl sim/63 GHz for both the HFET and the MISHFET. This corresponds to an average effective electron velocity in the MISHFET channel of 9.9/spl times/10/sup 6/ cm/s. The knee voltage and current saturation mechanisms in submicron MISHFETs and heterostructure field-effect transistors (HFET) are also discussed.
A Phase I/II Clinical Trial of β‐Globin Gene Therapy for β‐Thalassemia (2005)

Recent success in the long-term correction of mouse models of human beta-thalassemia and sickle cell anemia by lentiviral vectors and evidence of high gene transfer and expression in transduced human hematopoietic cells have led to a first clinical trial of gene therapy for the disease. A LentiGlobin vector containing a beta-globin gene (beta(A-T87Q)) that produces a hemoglobin (Hbbeta(A-T87Q)) that can be distinguished from normal hemoglobin will be used. The LentiGlobin vector is self-inactivating and contains large elements of the beta-globin locus control region as well as chromatin insulators and other features that should prevent untoward events. The study will be done in Paris with Eliane Gluckman as the principal investigator and Philippe Leboulch as scientific director.
Towards fully distributed amplification and high-performance long-range distributed sensing based on random fiber laser (2012)

The random distributed feedback fiber laser (RDFB-FL), firstly proposed and demonstrated by S. K. Turitsyn et al., has been designated as the significant breakthrough in the fields of laser physics and nonlinear optics. In this paper, the fully distributed Raman amplification approach, based on the novel concept of RDFB-FL, is proposed and presented for the first time. As a typical proof-of-concept, the high-performance distributed sensing with ±1°C temperature accuracy and ±2m spatial resolution, over entire 122km long-range Brillouin optical time-domain analyzer (BOTDA), has been demonstrated using the fully distributed second-order Raman amplification based on RDFB-FL proposed. The experimental results confirmed its unique ultra-low noise performance for the proposed distributed amplification. We believe it's the best sensing result for such a length of BOTDA so far. The underlined physical mechanisms associated with its quasi-lossless transmission and partial coherence characteristics, are also presented, in order to account for this much attractive feature.
