A decentralized architecture for Active Sensor Networks (2004)

The paper presents a decentralized approach to the solution of the distributed information gathering problem. The main design objectives are scalability with the number of network components, maximum flexibility in implementation and deployment, and robustness to component and communication failure. The design approach emphasizes interactions between components rather than the definition of the components themselves. The architecture specifies a small set of interfaces sufficient to implement a wide range of information gathering systems. The results of two deployment scenarios on an indoor sensor network are presented.
A marker-free system for the analysis of movement disabilities. (1998)

A major step toward improving the treatments of disabled persons may be achieved by using motion analysis equipment. We are developing such a system. It allows the analysis of plane human motion (e.g. gait) without using the tracking of markers. The system is composed of one fixed camera which acquires an image sequence of a human in motion. Then the treatment is divided into two steps: first, a large number of pixels belonging to the boundaries of the human body are extracted at each acquisition time. Secondly, a two-dimensional model of the human body, based on tapered superquadrics, is successively matched with the sets of pixels previously extracted; a specific fuzzy clustering process is used for this purpose. Moreover, an optical flow procedure gives a prediction of the model location at each acquisition time from its location at the previous time. Finally we present some results of this process applied to a leg in motion.
Dependable computing and online testing in adaptive and configurable systems (2000)

We describe cost-effective design techniques for very dependable high-performance adaptive computing systems. These design techniques take advantage of the particular properties of adaptive computing systems.
A Study of the Dispersity of Catalytic Sites in Ethylene/Propylene Copolymerization Through Computer-Assisted<sup>13</sup>C NMR Analysis (1996)

Abstract A series of ethylene(E)/propylene(P) copolymers covering a large range of compositions is obtained by a new solution copolymerization process. The catalyst system consists of a high-activity, high-regioselectivity and high-stereospecificity Ti complex supported on MgCl2. The cocatalyst is triethylaluminum treated with diphenyldimethoxysilane. The polymers are studied by 13C NMR, and the E- and P-centered triads analyzed via the computer-assisted analytical approach. Through a systematic analysis, one can determine the minimum number of components that are needed to fit the data. Each component would correspond to a family of similar catalytic sites. The reactivity ratios (rE and rP ) of each family of active sites and the component weight factor (related to the catalytic activity) are also determined.
Comprehensive MR Imaging Protocol for Stroke Management: Tissue Sodium Concentration as a Measure of Tissue Viability in Nonhuman Primate Studies and in Clinical Studies (1999)

Tissue sodium concentration provides a sensitive measure of tissue viability that is complementary to the diagnostic role of diffusion and perfusion imaging for ischemic insult.
Evaluation of survival and ischaemic and thromboembolic event rates in patients with non-valvar atrial fibrillation in the general population when treated and untreated with warfarin (2005)

Patients with NVAF within the recommended target INR range of 2.0-3.0 survive longer and have reduced morbidity. Probably too few people are anticoagulated with warfarin in NVAF.
Analysis of consumer cosmetic products for phthalate esters. (2006)

A rapid and sensitive reverse-phase HPLC method with UV detection was developed for the quantitation of dimethyl phthalate (DMP), diethyl phthalate (DEP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP), and di(2-ethylhexyl) phthalate (DEHP) in cosmetic preparations. Average recoveries of the phthalate esters were better than 90%. In a survey of 48 consumer cosmetic products, including hair care products, deodorants, lotions and creams, nail products, fragrances, and body washes, most products were found to contain at least one phthalate ester. DEP was detected most frequently at concentrations up to 38,663 ppm. DBP was found in fewer products, but at levels up to 59,815 ppm. Based on the available exposure and toxicity data, the FDA has concluded that there is insufficient data to conclude that a human health hazard exists from exposure to phthalate esters from cosmetic products.

Molecular diagnostic tests for ascertainment of genotype at the rod cone dysplasia 1 (<i>rcd1</i>) locus in Irish setters (1995)

Rod-cone dysplasia type 1 (rcd1) is one of several canine photoreceptor degenerations, collectively termed progressive retinal atrophy (PRA), that afflict different breeds of dogs. The rcd1 phenotype is an early onset autosomal recessive disease caused by a nonsense amber mutation, at codon 807, in the canine gene for the beta-subunit of rod cyclic GMP phosphodiesterase (canine PDEB). The mutation involves a G to A transition at nucleotide position 2420, which presumably would cause premature termination of the canine PDEB protein by 49 amino acid residues. In both a small pedigree study of Irish setters from the United Kingdom and in larger canine pedigree studies in the United States, this gene defect has been found to be the only mutation causing rcd1. Here we report development of a diagnostic test which unequivocally distinguishes the three genotypes at the rcd1 locus: rcd1/rcd1 (homozygous mutant, affected); rcd1/+ (heterozygous, carrier); and +/+ (homozygous normal, wildtype).
Contact and Residual Sprays for Furniture Carpet Beetle (FCB) Control, 1980 (1981)

Abstract The objective of these tests was to evaluate the performance of several insecticides that might be used to control FCB larvae. Textile resistance tests outlines by the Chemical Specialities Manufactures Association (CSMA) were modified to assess the efficacy of direct contact sprays and residual deposits. Larvae were tested because only immature FCB damage materials such as woolen or contaminated fabrics, leather, furs and feathers. Adults are short-lived compared to larvae and reportedly feed on pollen and nectar. FCB larvae for these tests were collected from cultures maintained at 27°C, 70-75% RH on medium comprised of dry dog chow, yeast and turkey feathers. Approximately half-grown larvae (2-3 mg, 3 mm long), which were retained on a no. 16 screen, were placed on flat glass beneath a warm light bulb. Larvae were aspirated into gloss shell vials as they moved to the edge of the glass. Five groups of 15 larvae placed in a clean 500 ml beaker were sprayed with two pumps (0.5 ml) from a deVilbiss #152 bulb sprayer from ca 7 inch. The thoroughly wetted larvae were transferred to filter paper to remove excess spray before they were placed in 26 sq cm plastic boxes the floors of which were covered with wool felt lightly dusted with a dog chow-yeast mixture. For residual activity, 5 groups of 20 larvae were confined to 26 sq cm felt treated with 0.13 ml dilute insecticide (1%=73 mg ai/sq ft.) The number dead was recorded ca daily up to 14 days. Each piece of wool was tested only once. Treatments were evaluated 28 and 56 days old.
Differentiating surface and bulk interactions in nanoplasmonic interferometric sensor arrays (2014)

Detecting specific target analytes and differentiating them from interfering background effects is a crucial but challenging task in complex multi-component solutions commonly encountered in environmental, chemical, biological, and medical sensing applications. Here we present a simple nanoplasmonic interferometric sensor platform that can differentiate the adsorption of a thin protein layer on the sensor surface (surface effects) from bulk refractive index changes (interfering background effects) at a single sensing spot, exploiting the different penetration depths of multiple propagating surface plasmon polaritons excited in the ring-hole nanoplasmonic sensors. A monolayer of bovine serum albumin (BSA) molecules with an effective thickness of 1.91 nm is detected and differentiated from a 10(-3) change in refractive index unit for the bulk solution. The noise level of the retrieved real-time sensor output compares favorably with that of traditional prism-based surface plasmon resonance sensors, but is achieved using a significantly simpler collinear transmission geometry and a miniaturized sensor footprint.

A design of CMOS voltage doubler for 1 V operation (2002)

The design of a new charge pump cell used to make a voltage doubler working under 1 V supply voltage is presented. A new idea of using a minimum-sized transistor to startup the charge pump, instead of the existing cross-coupled method, makes the charge pump cell more suitable for on-chip application because of its simpler design and smaller area. A fully integrated charge pump based on the cell is also presented.
Development of ultrasonic transducers for ranging and imaging in heavy liquid metal (2006)

The paper describes the development of high temperature, /spl gamma/ and neutron radiation resistant ultrasonic transducers which must operate continuously in liquid Pb/Bi up to 450/spl deg/C. Known ultrasonic transducers are not intended for such harsh conditions. The main problems are acoustic coupling of the piezoelement to the protector and wetting of the transducer by a heavy liquid metal. For the first time, the piezo-element was attached to the transducer body by a gold-to-gold diffusion bonding process; acoustic coupling between the transducer and the liquid metal alloy was achieved by coating the front face by a protective diamond-like carbon (DLC) layer. Due to the high radiation, only a limited number of materials may be used in the transducer design. Transducers with bismuth titanate piezoelectric elements showed no noticeable changes of pulse responses and transfer coefficients. The housing of the transducer is made of AISI 316 stainless steel, it is laser welded and high temperature 1 mm diameter, 15 m long, mineral cable is used.
Get the data. (2001)

Numerous studies affirm the benefit of rapid defibrillation with AEDs. Most of the data have been acquired in emergency medical response systems with EMTs or firefighters providing defibrillation. Yet interest is growing in the provision of rapid defibrillation by other responders, including security officers, flight attendants and laypersons trained as targeted responders. This expansion is embraced in community early defibrillation. A multicenter, prospective, randomized, controlled trial was recently launched to define the benefit of community early defibrillation. Data from this trial will likely identify the most effective deployment of AEDs, frequency and appropriateness of use, time of defibrillation before EMS arrival, device maintenance issues and--most importantly--survival benefit when compared with control groups without AEDs.
Voice or Gesture in the Operating Room (2015)

This case study represents our efforts to investigate the uses of voice control versus gestural control in the OR. We present a system we expressly built to allow for both gestural or voice control at the choice of the surgeon. We explain our deployment of this system in the context of cardiothoracic surgery and present a vignette on how the system was used in the moment by the attending surgeon. We learn that, in terms of design, its not just a question of saying voice is better for one type of functionality and gesture is better for another; rather, the benefits are circumstantial. Thus, there is a case for building in redundancy in control with both voice and gesture.
Variation in Performance of Neonatal Intensive Care Units in the United States (2017)

From 2005 to 2014, rates of death prior to discharge and serious morbidities decreased among the NICUs in this study. Within 8 years, 75% of NICUs achieved rates of performance from the best quartile of the 2005 benchmark for all outcomes except chronic lung disease. These findings provide a novel way to quantify the magnitude and pace of improvement in neonatology.
SPATIALLY PRE-PROCESSED SPEECH DISTORTION WEIGHTED MULTI -CHANNEL WIENER FILTERING FOR NOISE REDUCTION IN HEARING AIDS (2003)

In this paper we establish a generalized noise reduction scheme, called the Spatially Pre-processed Speech Distortion Weighted Multi-channel Wiener filter (SP-SDW-MWF), that encompasses the Generalized Sidelobe Canceller (GSC) and a recently developed Multi-channel Wiener Filtering (MWF) technique as extreme cases and allows for in-between solutions. Compared to the widely studied GSC with Quadratic Inequality Constraint (QIC-GSC), the SP-SDW-MWF achieves a better noise reduction performance, for a given maximum speech distortion level.

The polygon method is superior to the conventional inked margin method in sensitivity. Furthermore, it covered all the peripheral margins and pinpointed the positive sites.
Low temperature bonding for 3D (2014)

Chemical interactions exist always between atoms on mated solids as the nature of solid surface. These interactions are origin of the adhesion energy between solids. It means that any solid materials should be bonded even if there is neither high temperature reaction nor diffusion process. This is the idea on which the surface activated bonding (SAB) at room temperature is based. Recent development of the SAB combining several processes of the surface activation provides a bridge to the conventional wafer bonding technique for bonding in ambient atmosphere.
The First Crystal Structure of Archaeal Aldolase (2003)

A gene encoding a 2-deoxy-d-ribose-5-phosphate aldolase (DERA) homolog was identified in the hyperthermophilic Archaea Aeropyrum pernix. The gene was overexpressed in Escherichia coli, and the produced enzyme was purified and characterized. The enzyme is an extremely thermostable DERA; its activity was not lost after incubation at 100 degrees C for 10 min. The enzyme has a molecular mass of approximately 93 kDa and consists of four subunits with an identical molecular mass of 24 kDa. This is the first report of the presence of tetrameric DERA. The three-dimensional structure of the enzyme was determined by x-ray analysis. The subunit folds into an alpha/beta-barrel. The asymmetric unit consists of two homologous subunits, and a crystallographic 2-fold axis generates the functional tetramer. The main chain coordinate of the monomer of the A. pernix enzyme is quite similar to that of the E. coli enzyme. There was no significant difference in hydrophobic interactions and the number of ion pairs between the monomeric structures of the two enzymes. However, a significant difference in the quaternary structure was observed. The area of the subunit-subunit interface in the dimer of the A. pernix enzyme is much larger compared with the E. coli enzyme. In addition, the A. pernix enzyme is 10 amino acids longer than the E. coli enzyme in the N-terminal region and has an additional N-terminal helix. The N-terminal helix produces a unique dimer-dimer interface. This promotes the formation of a functional tetramer of the A. pernix enzyme and strengthens the hydrophobic intersubunit interactions. These structural features are considered to be responsible for the extremely high stability of the A. pernix enzyme. This is the first description of the structure of hyperthermophilic DERA and of aldolase from the Archaea domain.
Study of chloroacetic acid production by chlorination of acetic acid in the presence of acid anhydride catalyst (2001)

In packed column reactor,title chloroacetic acid production process is studied through changing reaction conditions,such as reaction temperature,mass ratio of acetic anhydride to acetic acid and so on.The suitable conditions are as follows:temperature is 110 ℃,mass ratio of acid anhydride to acetic acid is above 12% and acid anhydride catalyst should be mixed with acetic acid before addition to reactor.The results show that chloroacetic acid production by reaction rectification in packed column reactor is feasible,and deeper chlorination products aren't detected.
Achievements and Challenges in Antiviral Drug Discovery (2005)

The last 40 years have seen the development of several antiviral drugs with therapeutic value in treating life-threatening or debilitating diseases such as those caused by HIV, hepatitis B virus, herpesviruses (such as herpes simplex virus and varicella zoster virus) and influenza virus. These relatively recent advances have been due to technical breakthroughs in the cultivation of viruses in the laboratory, identification of viral enzymes and, more recently, their molecular biology. We describe here the antecedence of several of the existing antivirals and their strengths and weaknesses. We indicate where the major challenges lie for future improvements of current therapies and possible new indications, such as hepatitis C virus and papillomavirus. We also describe how current antiviral therapies are restricted to a rather limited number of viral diseases of sufficient interest to the pharmaceutical industry. Finally we describe the potential threat of emerging viruses and bio-weapons and the challenges that they present to therapy.

Autoregulated changes in stability of polyribosome-bound beta-tubulin mRNAs are specified by the first 13 translated nucleotides. (1988)

The expression of tubulin polypeptides in animal cells is controlled by an autoregulatory mechanism whereby increases in the tubulin subunit concentration result in rapid and specific degradation of tubulin mRNAs. We have now determined that the sequences that are necessary and sufficient to specify mouse beta-tubulin mRNAs as substrates for this autoregulated instability reside within the first 13 translated nucleotides (which encode the first four beta-tubulin amino acids Met-Arg-Glu-Ile). This domain has been functionally conserved throughout evolution, inasmuch as sequences isolated from the analogous region of human, chicken, and yeast beta-tubulin mRNAs also confer autoregulation. Further, for an RNA to be a substrate for regulation, not only must it carry the 13-nucleotide coding sequence, but it must also be ribosome bound and its translation must proceed 3' to codon 41.
Gamma Irradiation: Effects on Biomechanical Properties of Human Bone-Patellar Tendon-Bone Allografts (1995)

Sixty 10-mm bone-patellar tendon-bone allografts from young human donors were placed into four test groups, a control fresh-frozen group and three fresh-frozen ir radiated groups. The irradiated groups were exposed to 2.0, 3.0, or 4.0 Mrad of gamma irradiation. The speci mens were tested to tensile failure. The initial biome chanical strength of fresh-frozen allografts was reduced up to 15% when compared with fresh-frozen controls after 2.0 Mrad of irradiation. Maximum force, strain en ergy, modulus, and maximum stress demonstrated a statistically significant reduction after 2.0 Mrad of irra diation ( P< 0.01). Stiffness, elongation, and strain were reduced but not with statistical significance. A 10% to 24% and 19% to 46% reduction in all biomechanical properties were found after 3.0 ( P < 0.005) and 4.0 ( P < 0.0005) Mrad of irradiation, respectively. After irra diation with a 4.0 Mrad dose, the ultimate load was be low that of reported values for the human anterior cru ciate ligament. It is clinically important to observe and document changes in human ligaments that result from currently used doses of gamma irradiation. The results from this study provide important information regarding the initial biomechanical properties of fresh-frozen hu man bone-patellar tendon-bone allografts after bacte rial sterilization with gamma irradiation. The current ac cepted dose for sterilization is between 1.5 and 2.5 Mrad. There appeared to be a dose-dependent effect of irradiation on all the biomechanical parameters studied. Four of seven parameters were found to be reduced after 2.0 Mrad of irradiation. Reductions were found in all parameters after 3.0 and 4.0 Mrad of irradiation.
Severe Plasmodium falciparum Malaria Is Associated with Circulating Ultra-Large von Willebrand Multimers and ADAMTS13 Inhibition (2009)

Plasmodium falciparum infection results in adhesion of infected erythrocytes to blood vessel endothelium, and acute endothelial cell activation, together with sequestration of platelets and leucocytes. We have previously shown that patients with severe infection or fulminant cerebral malaria have significantly increased circulatory levels of the adhesive glycoprotein von Willebrand factor (VWF) and its propeptide, both of which are indices of endothelial cell activation. In this prospective study of patients from Ghana with severe (n = 20) and cerebral (n = 13) P. falciparum malaria, we demonstrate that increased plasma VWF antigen (VWF:Ag) level is associated with disproportionately increased VWF function. VWF collagen binding (VWF:CB) was significantly increased in patients with cerebral malaria and severe malaria (medians 7.6 and 7.0 IU/ml versus 1.9 IU/ml; p<0.005). This increased VWF:CB correlated with the presence of abnormal ultra-large VWF multimers in patient rather than control plasmas. Concomitant with the increase in VWF:Ag and VWF:CB was a significant persistent reduction in the activity of the VWF-specific cleaving protease ADAMTS13 (approximately 55% of normal; p<0.005). Mixing studies were performed using P. falciparum patient plasma and normal pooled plasma, in the presence or absence of exogenous recombinant ADAMTS13. These studies demonstrated that in malarial plasma, ADAMTS13 function was persistently inhibited in a time-dependent manner. Furthermore, this inhibitory effect was not associated with the presence of known inhibitors of ADAMTS13 enzymatic function (interleukin-6, free haemoglobin, factor VIII or thrombospondin-1). These novel findings suggest that severe P. falciparum infection is associated with acute endothelial cell activation, abnormal circulating ULVWF multimers, and a significant reduction in plasma ADAMTS13 function which is mediated at least in part by an unidentified inhibitor.
Neonatal and Pediatric Pulse Oximetry (2003)

The pulse oximeter has become a vital instrument in the care of infants and children with cardiopulmonary disease. Recent advances in pulse oximetry technology have improved some aspects of pulse oximeter performance. However, the reliability, accuracy, and clinical utility of pulse oximetry remain problematic in some types of patients under certain conditions. Improved signal processing technology has substantially improved the ability of certain oximeters to work reliably under conditions of poor perfusion and motion artifact. There is a growing body of evidence describing the effect of pulse oximeter utilization on processes and outcomes. This article describes the principles, limitations, current state of oximetry technology, and the impact of oximetry data and alarms on diagnosis and clinical decision-making.
