PhaseBeat: Exploiting CSI Phase Data for Vital Sign Monitoring with Commodity WiFi Devices (2017)

Vital signs, such as respiration and heartbeat, are useful to health monitoring since such signals provide important clues of medical conditions. Effective solutions are needed to provide contact-free, easy deployment, low-cost, and long-term vital sign monitoring. In this paper, we present PhaseBeat to exploit channel state information (CSI) phase difference data to monitor breathing and heartbeat with commodity WiFi devices. We provide a rigorous analysis of the CSI phase difference data with respect to its stability and periodicity. Based on the analysis, we design and implement the PhaseBeat system with off-the-shelf WiFi devices, and conduct an extensive experimental study to validate its performance. Our experimental results demonstrate the superior performance of PhaseBeat over existing approaches in various indoor environments.
Event Schema Induction with a Probabilistic Entity-Driven Model (2013)

Event schema induction is the task of learning high-level representations of complex events (e.g., a bombing) and their entity roles (e.g., perpetrator and victim) from unlabeled text.Event schemas have important connections to early NLP research on frames and scripts, as well as modern applications like template extraction.Recent research suggests event schemas can be learned from raw text.Inspired by a pipelined learner based on named entity coreference, this paper presents the first generative model for schema induction that integrates coreference chains into learning.Our generative model is conceptually simpler than the pipelined approach and requires far less training data.It also provides an interesting contrast with a recent HMM-based model.We evaluate on a common dataset for template schema extraction.Our generative model matches the pipeline's performance, and outperforms the HMM by 7 F1 points (20%).
Research on Domain-specific Embedded Languages and Program Generators (1998)

Embedding is the process of implementing a language by defining functions in an existing “host” Language; the host language with these added functions is the new language. As a consequence; the new language comes equipped with all the features of the host language, with no additional work on the part of the language designer. Embedding works particularly well when the host language is a functional language. We describe several examples of embedded languages. The first is a language for specifying simple pictures. The others are program generators, that is, languages used to specify programs in other languages. In all of these examples, the host language is Standard ML; in the program generating languages, the target language is C+plus;. The power obtained from the host language is the main emphasis of our presentation.

Inductance-less up DC-DC convertor (1982)

A new type of up convertor which does not include inductance is described. Voltage multiplication is achieved by charging the capacitors in parallel and discharging them in series. The circuit includes two groups of switched capacitors which are alternately connected to the source and the load, such that the input charging pulses and output ripple are reduced, compared with a circuit including only one group of switched capacitors. This type of convertor may be applied in high-voltage systems, and because there is no inductance, it can also be included in integrated circuits.
Smart Contract Templates: foundations, design landscape and research directions (2016)

In this position paper, we consider some foundational topics regarding smart contracts (such as terminology, automation, enforceability, and semantics) and define a smart contract as an automatable and enforceable agreement. We explore a simple semantic framework for smart contracts, covering both operational and non-operational aspects, and describe templates and agreements for legally-enforceable smart contracts, based on legal documents. Building upon the Ricardian Contract, we identify operational parameters in the legal documents and use these to connect legal agreements to standardised code. We also explore the design landscape, including increasing sophistication of parameters, increasing use of common standardised code, and long-term research.
Enantioselective Synthesis of Primary 1-(Aryl)alkylamines by Nucleophilic 1,2-Addition of Organolithium Reagents to Hydroxyoxime Ethers and Application to Asymmetric Synthesis of G-Protein-Coupled Receptor Ligands (2004)

(E)-Arylaldehyde oxime ethers bearing a (1S)-2-hydroxy-1-phenylethyl or (2R)-1-hydroxy-2-phenylethyl group as a chiral auxiliary, both derived from a single precursor, methyl (R)-mandelate, underwent nucleophilic addition with organolithium reagents via six-membered chelates to give the diastereomerically enriched (R)- and (S)-adducts, respectively, which, after chiral auxiliary removal by reductive N-O bond cleavage, led to the corresponding (R)- and (S)-1-(aryl)ethylamines. This organolithium addition protocol using methyllithium was applied in an enantiodivergent fashion to the preparation of both enantiomers of 1-(2-hydroxyphenyl)ethylamine, which has been previously used as an efficient chiral auxiliary for the synthesis of natural products in this laboratory. The synthetic utility of this methodology involving diastereoselective methyl addition was demonstrated by further application to the asymmetric synthesis of a new type of calcium receptor agonist (calcimimetics), (R)-(+)-NPS R-568 and its thio analogue. Furthermore, diastereoselective vinylation was accomplished by application of the hydroxy oxime ether-based protocol using vinyllithium, which allowed the development of the enantioselective synthesis of the NK-1 receptor antagonists, (+)-CP-99,994 and (+)-CP-122,721.
Folate deficiency in depressive illness. (1970)

Serum folate and vitamin B12 levels have been measured in 101 patients with depressive illness. Subnormal folate levels (2.5 ng./ml. or less) were found in 24 per cent and subnormal vitamin B12 levels (150 pg./ml. or less) in 2.2 per cent of patients. Thirteen patients(14.4 per cent) had low vitamin B12 levels (200 pg./ml. or less). Patients with subnormal folate levels were found to have significantly higher depressive scores, and significantly lower validity scores on the Marke-Nyman Temperament Scale, both on admission and on discharge. Subnormal folate levels could be a consequence of dietary deficiency or could possibly be causal of depression through interference with tyrosine or tryptophan hydroxylation.
An effective therapy for both undifferentiated (including Burkitt's) lymphomas and lymphoblastic lymphomas in children and young adults (1984)

We have used a single intensive chemotherapy regimen in the treatment of young patients with diffuse, aggressive, malignant lymphomas. There were two major histologic types of lymphoma in our series: lymphoblastic lymphomas, which presented most often with mediastinal tumor (64%), and undifferentiated lymphomas (mostly Burkitt’s lymphomas), which occurred predominantly in the abdomen (86%). Our objective was to examine the determinants of prognosis in a uniformly treated patient group that included 31 children (2–16 yr) and 34 young adults 17–35 yr). Patients with extensive bone marrow involvement (greater than 50% replacement by tumor cells) were included in the study. Treatment consisted essentially of a 4-drug combination (cytoxan, adriamycin, vincristine, and prednisone) alternating with a 42-hr methotrexate infusion, followed by leukovorin rescue, and included intrathecal prophylactic therapy against central nervous system (CNS) disease. Patients with localized or resected undifferentiated lymphoma received 6 therapy cycles; all other patients received 15 cycles. Radiation therapy was used only in exceptional circumstances. Fifty-eight of 65 patients (89%) achieved complete remission: 97% of children and 82% of adults. The estimated 3-yr survival was 60% (SE 6.4%) with a median follow-up of 3 yr. Analysis of factors associated with remission duration and survival indicated that bone marrow involvement at referral and extensive disease were poor prognostic variables. Patients with lymphoblastic lymphomas and patients with completely resected undifferentiated lymphomas had the best prognosis (81% +/- 12% and 94% +/- 6% estimated 3-yr survival, respectively). Patients with extensive intraabdominal undifferentiated lymphoma (stage D) had the worst prognosis (33% +/- 11% estimated 3 yr survival), but even in this subgroup, bone marrow involvement was an adverse factor (estimated survival in stage D patients with and without bone marrow involvement was 14% +/- 13% and 43% +/- 15%, respectively). Elevated uric acid and/or lactic dehydrogenase (LDH) were also of prognostic significance, but predominantly reflected state, i.e., extent of disease. Age did not significantly influence prognosis. In the undifferentiated lymphoma subgroup, histology (i.e., Burkitt's lymphoma versus non-Burkitt’s lymphoma) was not of prognostic significance. Total white count was below 1,000/cu mm in 39% of cycles, and fever associated with granulocytopenia occurred in 17% of cycles. Stomatitis of moderate to severe extent occurred in 50% of cycles.(ABSTRACT TRUNCATED AT 400 WORDS)
Controlling muscle mitochondrial content (2003)

Mitochondrial content, a chief determinant of aerobic capacity, varies widely among muscle types and species. Mitochondrial enzyme levels in vertebrate skeletal muscles vary more than 100-fold, from fish white muscle to bird flight muscles. Recent studies have shed light on the transcriptional regulators that control mitochondrial gene expression in muscle fiber differentiation and development, and in the context of pathological conditions such as neuromuscular disease and obesity. While the transcriptional co-activator PGC-1alpha (peroxisome proliferator-activated receptor gamma co-activator 1) has emerged as a master controller of mitochondrial gene expression, it is important to consider other mechanisms by which coordinated changes in mitochondrial content could arise. These studies, largely using biomedical models, provide important information for comparative biologists interested in the mechanistic basis of inter-species variation in muscle aerobic capacity.
Sampling and reconstruction effects due to motion in diffusion‐weighted interleaved echo planar imaging (2000)

Subject motion during diffusion-weighted interleaved echo-planar imaging causes k-space offsets which lead to irregular sampling in the phase-encode direction. For each image, the k-space shifts are monitored using 2D navigator echoes, and are shown to lead to a frequent violation of the Nyquist condition when an ungated sequence is used on seven subjects. Combining data from four repeat acquisitions allows the Nyquist condition to be satisfied in all but 1% of images. Reconstruction of the irregularly-sampled data can be performed using a matrix inversion technique. The repeated acquisitions make the inversion more stable and additionally improve the signal-to-noise ratio. The resultant isotropic diffusion-weighted images and average apparent diffusion coefficient (ADC) maps show high resolution and enable clear localization of a stroke lesion. Residual ADC artifacts with a slow spatial variation are observed and assumed to originate from non-rigid pulsatile brain motion. Magn Reson Med 44:101–109, 2000. © 2000 Wiley-Liss, Inc.
The Pseudomonas aeruginosa acsA gene, encoding an acetyl-CoA synthetase, is essential for growth on ethanol (2001)

Pseudomonas aeruginosa ATCC 17933 uses a pyrroloquinoline quinone-dependent ethanol oxidation system. Two mutants of P. aeruginosa, unable to grow on ethanol and showing no acetyl-CoA synthetase (ACS) activity under standard test conditions, were complemented by cosmid pTB3018. Subcloning led to the isolation of a gene which encodes a protein with high similarity to acetyl-CoA synthetases. Interruption of the putative acsA gene by a kanamycin-resistance cassette resulted in a mutant also unable to grow on ethanol and with very low residual acetyl-CoA-forming activity. Complementation by the wild-type allele of the acsA gene restored growth and led to the expression of ACS activity in excess of that of wild-type cells. In wild-type P. aeruginosa, ACS activity was induced upon growth on ethanol, 2,3-butanediol, malonate and acetate. The wild-type and mutants defective in ACS activity showed an active acetate kinase (ACK) under the growth conditions used; however, phosphotransacetylase (PTA) could not be detected. The data indicate that P. aeruginosa requires active acsA gene product for growth on ethanol.
Nursing Research in HIV/AIDS Home Care, Part 1 (1995)

One of the primary goals of nursing research is to develop a systematic body of knowledge to guide nursing practice. In the community setting, an extremely useful method of research is the exploratory field study, which can be used to discover important variables that may exist in real-life situations. This study reflects an analysis of the problems that were identified in persons living with human immunodeficiency virus/acquired immune deficiency syndrome in New York City who were referred for home care services. Part I presents an overview of nursing research methods, focusing on an actual field study in human immunodeficiency virus/acquired immune deficiency syndrome home care; Part II describes the results and implications for nursing.

Algorithm for repeated clipping and filtering in peak-to-average power reduction for OFDM (2002)

Repeated clipping and filtering is an effective peak reduction method to achieve a desired peak-to-average power ratio for OFDM. An efficient implementation of the repeated process in which no IFFT and FFT are required is presented. The complexity of the new implementation is much less than that of the original method.

A coupled wellbore/reservoir simulator to model multiphase flow and temperature distribution (2007)

Hydrocarbon reserves are generally produced through wells drilled into reservoir pay zones. During production, gas liberation from the oil phase occurs due to pressure decline in the wellbore. Thus, we expect multiphase flow in some sections of the wellbore. As a multi-phase/multi-component gas-oil mixture flows from the reservoir to the surface, pressure, temperature, composition, and liquid holdup distributions are interrelated. Modeling these multiphase flow parameters is important to design production strategies such as artificial lift procedures. A wellbore fluid flow model can also be used for pressure transient test analysis and interpretation. Considering heat exchange in the wellbore is important to compute fluid flow parameters accurately. Modeling multiphase fluid flow in the wellbore becomes more complicated due to heat transfer between the wellbore fluids and the surrounding formations. Due to mass, momentum, and energy exchange between the wellbore and the reservoir, the wellbore model should be coupled with a numerical reservoir model to simulate fluid flow accurately. This model should be non-isothermal to consider the effect of temperature. Our research shows that, in some cases, ignoring compositional effects may lead to errors in pressure profile prediction for the wellbore. Nearly all multiphase wellbore simulations are currently performed using the "black oil" approach. The primary objective of this study was to develop a non-isothermal wellbore simulator to model transient fluid flow and temperature and couple the model to a reservoir simulator called General Purpose Adaptive Simulator (GPAS). The coupled wellbore/reservoir simulator can be applied to steady state problems, such as production from, or injection to a reservoir as well as during transient phenomena such as well tests to accurately model wellbore effects. Fluid flow in the wellbore may be modeled either using the blackoil approach or the compositional approach, as required by the complexity of the fluids. The simulation results of the new model were compared with field data for pressure gradients and temperature distribution obtained from wireline conveyed pressure recorder and acoustic fluid level measurements for a gas/oil producer well during a buildup test. The model results are in good agreement with the field data. Our simulator gave us further insights into the wellbore dynamics that occur during transient problems such as phase segregation and counter-current multiphase flow. We show that neglecting these multiphase flow dynamics would lead to unreliable results in well testing analysis.
COMPARISON OF INSTRUMENTAL METHODS FOR MEASURING SEED HARDNESS OF FOOD‐GRADE SOYBEAN (2008)

ABSTRACT Breeding specialty soybeans for the soyfood market requires proper methodology in evaluation of seed quality attributes. In this study, efficient methods that could be potentially used for testing soybean seed hardness were developed by examining different instruments and seed parameters. Five food‐grade soybean genotypes with different seed sizes were used to determine seed water‐absorption capacity and hardness. Water absorption capacity was expressed by swell ratios for seed weight, seed dimension, and volume of water changes before and after soaking. Seed hardness test was conducted by a one‐bite method using a food texture analyzer equipped with five different probes. The results showed that hardness testing by a 75 mm cylinder with 10 steamed seeds, single blade with five steamed seeds, and shear cell with 30 g steamed seeds produced dependable and consistent results with low coefficient of variance. However, shear cell may not be practical for early plant selection in a breeding program due to a relatively large sample requirement. Seed size can be used as indirect selection indicators for seed hardness. PRACTICAL APPLICATIONS Seed hardness is an important factor in determining soybean suitability for natto production. This study used two texture analyzers equipped with five different probes to test hardness of five soybean genotypes with different seed size. The methodologies for testing the seed texture of soybean have been established, which can help regulate the seed hardness testing for commercial production and provide consistent hardness references for natto breeding programs and the seed industry.
A review on the catalytic combustion of soot in Diesel particulate filters for automotive applications: From powder catalysts to structured reactors (2015)

The current soot oxidation catalyst scenario has been reviewed, the main factors that affect the activity of powder catalysts have been highlighted and kinetic soot oxidation models have been examined. A critical review of recent advances in modelling approaches has also been presented in this work. The multiscale nature of DPFs lends itself to a hierarchical organization of models, over various orders of magnitude. Different observation scales (e.g., wall, channel, entire filter) have often been addressed with separate modelling approaches that are rarely connected to one another, mainly because of computational difficulties. Nevertheless, DPFs exhibit an intrinsic multi-scale complexity that is reflected by a trade-off between fine and large-scale phenomena. Consequently, the catalytic behavior of DPFs usually results in a non-linear combination of multi-scale phenomena.
