Determination of Endotoxin-Neutralizing Capacity of Plasma in Postsurgical Patients (1996)

In 92 patients who underwent abdominal and goiter surgery endotoxin and endotoxin-neutralizing capacity (ENC) were determined in plasma preoperatively and daily postoperatively. Endotoxin plasma levels started to increase on day 1 in patients who were laparotomized. Correspondingly ENC was reduced during the 1st postoperative week. Even on the 1st postoperative day determination of ENC made the differentiation between patients possible who showed an uneventful course and patients who developed pneumonia, pulmonary failure, or mental disorders. Furthermore the need for diuretics in order to maintain sufficient renal function was associated with lower ENC during days 1-3. Endotoxin plasma levels were significantly elevated in patients who developed pneumonia during days 1-4, whereas the occurrence of pulmonary failure was only correlated with elevated endotoxin levels on day 3. Endotoxemia was pronounced in patients needing diuretics on days 1, 4, and 5. In patients who underwent goiter surgery ENC changed significantly as found for endotoxin plasma values during the postoperative course. Determination of endotoxin and especially ENC with the use of the limulus amebocyte lysate test turned out to be a reliable method correlating with impending complications at least in postsurgical patients.
A study of the transmission of ultrasound across solid–rubber interfaces (1997)

The reflection coefficient at the solid–rubber interface of a rubber coupled ultrasonic transducer may be used as a measure of its coupling performance; the lower the solid–rubber reflection coefficient, the better the coupling. An experimental and theoretical study of the transmission of ultrasound across dry coupled solid–rubber interfaces, and in particular the effect of surface roughness and particulate contaminants on solid coupling, is described. The effect of surface roughness is modeled using a numerical contact model of the solid–rubber interface from which the static stiffness is calculated. The calculated interfacial stiffness is then used in a spring model of the interface to predict the solid–rubber reflection coefficient behavior. By repeating this process for different loads applied to the solid–rubber interface the variation of reflection coefficient with interfacial pressure is found. The agreement between these predictions and the experiments is shown to be reasonable in general and good at higher pressures. The numerical contact model is then used to predict the pressure required to achieve a given level of coupling on a variety of surfaces. This modeling procedure can now be used to provide the operator of a dry coupled system with an estimate of the pressure which must be applied to a dry coupled transducer on a given system to achieve the required coupling. The effect of dust and dirt on the transmission of ultrasound across solid–rubber interfaces has been considered experimentally. These experiments showed that particulate contaminants at a solid coupled interface significantly reduce the degree of coupling and this effect is quantified.
Performance Evaluation of QoS Provisioning Techniques for VoIP (2006)

Voice over Internet Protocol (VoIP) or IP Telephony application is one of the most promising services that can be implemented over the Internet. It is gaining more and more popularity each day due to its bandwidth-efficient implementation and the possibilities of integrating VoIP with other Web-based applications. However, the lack of quality of service (QoS) in the IP network could deter the development of VoIP. Being a real time application, voice traffic is intolerant of delays, loss, and jitter. Thus, some measure of QoS provision is necessary. In this paper two QoS mechanisms for VoIP, namely integrated services (IntServ) and differentiated services (DiffServ), have been simulated and analyzed. The main objective of these simulations is to measure and compare the performance of the network that uses VoIP application under different types of QoS provisioning techniques.
MITION: a MAC-layer hybrid protocol for multi-channel real-time LANs (2002)

In this paper we present a hybrid MAC-layer protocol, named MITION, for multi-channel real-time LANs. The MITION protocol is based on the 1-p CSMA/CD scheme, using also a virtual token passing mechanism as the collision resolution algorithm. Additionally, it performs a channel selection algorithm, which provides an efficient "switching" operation for the selection of the available communication channels. The MITION protocol, due to its deterministic and multi-channel nature, offers high operational reliability and high performance under asynchronous and synchronous channel traffic.
Permanent multipole magnetic fields stored in superconductors (1973)

Hollow superconducting cylinders of Pb, Nb, and Nb3Sn were used to permanently store dipole, quadrupole, and sextupole magnetic fields with high fidelity to the original fields. Fields were trapped transversely to the axes of solid, hollow, and split hollow cylinders. This experimental demonstration indicates that it should be possible to store any multipole magnetic field configuration by this method. Important benefits should accrue to technologies dealing with the focusing of charged particle beams, such as accelerators, electron microscopes, etc. Use of field trapping permits determination of the fluxoid pinning force.
A Two-Wire IC Compatible Capacitive Transducer Circuit (1970)

The important features of the transducer bridge circuit considered here are that under certain conditions the circuit output can be made relatively independent of (1) changes in the carrier period, (2) changes in branch resistance, and (3) changes in capacitances due to temperature. Additional features are (4) the circuit is located at the transducer and (5) requires only two connecting leads to the necessary energizing and indicating equipment, and (6) the branch containing the transducer can be balanced by a pure resistor in the other branch. Each of these features is important for integrated circuit considerations. Some pressure transducer assemblies incorporating a hybrid integrated circuit version of the circuit bridge are shown in addition to sample calibrations.
New RISC processor control for direct drive sheeters (2002)

Sheeters use complex mechanical gears to perform the cutting operation of different paper sheet sizes. These gears set the cut length either hydraulically or with manual levers. They form an expensive part of the complete machine. To make it easier to revamp existing machines and also have more flexibility in the design of new ones, the direct drive sheeter was designed and built. There are no more gears, and a highly dynamic DC drive and control system determine the operation of the sheeter.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
<i>In situ</i> crosslinkable heparin‐containing poly(ethylene glycol) hydrogels for sustained anticoagulant release (2012)

Low-molecular weight heparin (LMWH) is widely used in anticoagulation therapies and for the prevention of thrombosis. LMWH is administered by subcutaneous injection usually once or twice per day. This frequent and invasive delivery modality leads to compliance issues for individuals on prolonged therapeutic courses, particularly pediatric patients. Here, we report a long-term delivery method for LMWH via subcutaneous injection of long-lasting hydrogels. LMWH is modified with reactive maleimide groups so that it can be crosslinked into continuous networks with four-arm thiolated poly(ethylene glycol) (PEG-SH). Maleimide-modified LMWH (Mal-LMWH) retains bioactivity as indicated by prolonged coagulation time. Hydrogels comprising PEG-SH and Mal-LMWH degrade via hydrolysis, releasing bioactive LMWH by first-order kinetics with little initial burst release. Separately dissolved Mal-LMWH and PEG-SH solutions were co-injected subcutaneously in New Zealand White rabbits. The injected solutions successfully formed hydrogels in situ and released LMWH as measured via chromogenic assays on plasma samples, with accumulation of LMWH occurring at day 2 and rising to near-therapeutic dose equivalency by day 5. These results demonstrate the feasibility of using LMWH-containing, crosslinked hydrogels for sustained and controlled release of anticoagulants.
Evaluating the performance of multicomputer configurations (1986)

Steps to optimize the performance of a multicomputer system (MCS) are discussed. Three aspects are emphasized: (1) the interconnection scheme that ties all the processors together, (2) the scheduling and mapping of the algorithm on the architecture, and (3) the mechanism for detecting parallelism and partitioning the algorithm into modules which achieve computational speedup when run on an MCS. Mapping and scheduling issues are addressed, and an application example is given.
Hyaline Membrane Disease Treated with Bovine Surfactant (1983)

Six preterm infants with severe hyaline membrane disease requiring ventilation were treated, at a median age of 15.5 hours, with a single intratracheal bolus of a bovine surfactant suspension. Arterial oxygenation increased dramatically, and chest radiograms showed improvement after two to four hours. However, a variable degree of deterioration occurred within 24 hours. All of the infants required oxygen therapy for several weeks, and one developed severe bronchopulmonary dysplasia.
Performance/Power Space Exploration for Binary64 Division Units (2015)

The digit-recurrence division algorithm is used in several high-performance processors because it provides good tradeoffs in terms of latency, area and power dissipation. In this work we develop a minimally redundant radix-8 divider for binary64 (double-precision) aiming at obtaining better energy efficiency in the performance-per-watt space. The results show that the radix-8 divider, when compared to radix-4 and radix-16 units, requires less energy to complete a division for high clock rates.
Backorders optimization in a one-warehouseN-identical retailer distribution system (1988)

This article examines the allocation of safety stock between sectors in a one-warehouse N-retailer distribution system which follows a (Q,R) inventory replenishment policy. In particular, the so-called „portfolio”︁ motive for holding warehouse safety-stock inventory is investigated. Two optimization problems involving the tradeoff between average system inventory investment and customer service, i.e., customer backorders, are considered and shown to be equivalent to a simpler optimization problem involving the tradeoff between customer service and system safety stock. Equivalence implies that the set of optimal policies for the simpler optimization problem provides all of the optimal policies for the more complex ones. This equivalence result is applied to the Deuermeyer and Schwarz (DS) model of the distribution system under study. Bounds on the set of optimal policies are provided. A heuristic for minimizing expected backorders with respect to a constraint on average system on-hand inventory is introduced, and empirical tests described. The heuristic, which prescribes little warehouse on-hand inventory, appears to be near optimal for the DS model. A simulation study supports this „near-zero”︁ inventory prescription for the warehouse.
Seasonal Changes in Mood and Behavior (1996)

There is a tendency for seasonal changes in mood and behavior to run in families, especially seasonality of the winter type, and this is largely due to a biological predisposition. These findings support continuing efforts to understand the role of seasonality in the development of mood disorders.
Dynamic reflection of RF signals from fluorescent lights: Their spectral analysis and effects on backscattered RFID tag signals (2007)

Radio frequency (RF) energy reflected from active power line ballast driven fluorescent tubes are known to be modulated at twice the line frequency. When the lamps are driven by electronic ballasts, it is found that the reflected (backscattered) RF wave is amplitude modulated with sidebands located at multiples of electronic ballast frequency components, extending to hundreds of kilohertz with significant power levels spread within this range. Detailed analysis of the measured sidebands spectrum indicated that the sidebands themselves are modulated at multiples of twice the power line frequency. Fluorescent lamps driven by different types of electronic ballasts operating at different unsynchronized frequencies exhibited different power levels. Consequently in an environment with abundance of active fluorescent lamps, the reflected RF signals can significantly affect the reception of modulated backscattered transponder RFID signals at UHF and higher bands.
Potential antiinflammatory compounds. 1. Antiinflammatory phenylpiperidine derivatives (1979)

The syntheses of a number of amines and their derivatives, based on the phenylpiperidine nucleus, are described. Their activities on the rat paw carrageenan test are also reported. Activities comparable to that of phenylbutazone were obtained for some of the amines, notably 4-piperidino-beta-methylphenethylamine.
Phosphonyl, Phosphonothioyl, Phosphonodithioyl, and Phosphonotrithioyl Radicals:  Generation and Study of Their Addition onto Alkenes (2003)

The treatment of benzyl dialkyl phosphites and dithiophosphites with benzeneselanyl chloride generates an Arbuzov-type transformation leading to the dialkyl selenophosphates 19a and 19b and to selenophosphorodithioates 21a and 21b. Interaction of these substrates with Lawesson's reagent yields the corresponding selenophosphorothioates 20a and 20b and the selenophosphorotrithioates 22a and 22b. When treated with a radical initiator in the presence of a hydrogen donor and an alkene, all eight phosphorus(V) precursors undergo homolytic cleavage of the P-Se bond to generate the phosphonyl, phosphonothioyl, phosphonodithioyl, or phosphonotrithioyl radicals. Most of these are shown to add onto electron-rich and electron-poor alkenes to deliver the expected adducts in fair to excellent yields. Cyclic precursor 19b displays peculiar behavior and, under the reaction conditions, produces only the corresponding cyclic phosphite. Application of this radical chain process is carried out on furanosyl 3-exo-methylene derivative 37 to diastereoselectively furnish five new 3-phosphonomethyl-, 3-phosphonothiomethyl-, and 3-phosphonodithiomethyl-3-deoxofuranoses 38a-c and 38f,g. The possibility of conducting tandem processes is also discussed through experiments involving (1R)-(+)-alpha-pinene (39) and diallylamine 41.
Fundamentals of polymers (2014)

In nanotechnology, polymers play a very important role as one of most often employed materials, especially in the fields of nanofibers and nanocomposites. Hundreds of polymers, including natural and synthetic polymers, have been fabricated into nanofibers and nanocomposites in the past 20 years. Thus a fundamental understanding of polymers, especially fiber-making polymers, is essential for people in various fields such as the biological, medical, electrical and material areas that are converging with nanotechnology.
Estimation of surface layer structure from Rayleigh wave dispersion: Dense data case (1977)

The problem of determining subsurface structure of a material from the measured dispersion of Rayleigh surface waves is obviously important in nondestructive testing and in the operation of surface acoustic wave devices. As is typical of many inverse problems this one is ill-posed and thus the use of special approaches is indicated. One approach is to represent possible profiles of the subsurface structure by trial functions containing a finite set of adjustable parameters and then find the parameter values giving the best fit to the dispersion data. Here we present an approach using a nonparametric version of estimation theory. This involves a mathematical model representing measurement errors and all possible profiles with reasonable a priori probability weightings. The present paper is limited to the case in which the dispersion data are dense (i.e., in a practical sense the data points are sufficiently dense on the frequency axis that interpolation can be performed with impunity). Later related papers will deal with the sparse data case. To elucidate the nature of the ill-posedness, a formal solution of the inverse problem is given in closed form. The application of estimation theory yields tractable estimator which corresponds to the inclusion of a convergence factor in the formal solution. The properties of the estimator are given by a set of auxiliary measures relating to statistical bias, model vs data dominance, resolution and reduction of variance. Because of the present lack of actual data sufficiently dense in a practical sense, synthetic test data, with and without simulated measurement noise, are used to investigate the performance of the estimator.
Increased prevalence of methylenetetrahydrofolate reductase C677T variant in patients with inflammatory bowel disease, and its clinical implications (1999)

There is an association between the thermolabile MTHFR C677T variant and IBD. This accounts in part for the raised plasma tHcy found in patients with IBD and may contribute to the increased incidence of thromboembolic complications. All patients with IBD should receive low dose folic acid and vitamin B(12) therapy to protect against the thromboembolic complications of raised tHcy.

Design and Analysis of Interleaved Boost Converter for Fuel Cell Applications (2011)

Fuel cell is one of the promising energy technologies for the sustainable future because of its high energy efficiency. For designing high efficiency fuel cell power systems, a suitable DC-DC converter is required. In this paper, an Interleaved Boost Converter (IBC) has been proposed as a suitable interface for fuel cells. IBC for fuel cell application reduces the ripple amplitude of the high frequency input current, avoids high frequency interaction inside the fuel cell stack and prolongs the fuel cell lifetime. A three-phase directly coupled IBC has been proposed in this paper compared to the conventional 2-phase IBC. The performance of IBC has been investigated over the operating range of the fuel cell. Detailed analysis has been done to investigate the relationship between ripple content, duty ratio and coupling coefficient. The design equations for IBC have been presented. The performance of IBC is studied for uncoupled and directly coupled inductors. Simulation study of IBC interfaced with fuel cells has been studied using MATLAB. Theoretical analysis and hardware prototype has been performed to validate the results.
Interpreting change on the WAIS-III/WMS-III in clinical samples (2001)

Clinicians should note that there is considerable variability in the reliabilities of the index and subtest scores derived from the third editions of the Wechsler Adult Intelligence Scale (WAIS-III) and the Wechsler Memory Scale (WMS-III). The purpose of this article is to review these reliabilities and to illustrate how they can be used to interpret change in patients' performances from test to retest. The WAIS-III IQ and Index scores are consistently the most reliable scores, in terms of both internal consistency and test-retest reliability. The most internally consistent WAIS-III subtests are Vocabulary, Information, Digit Span, Matrix Reasoning, and Arithmetic. Information and Vocabulary have the highest test-retest reliability. On the WMS-III, the Auditory Immediate Index, Immediate Memory Index, Auditory Delayed Index, and General Memory Index are the most reliable, in terms of both internal consistency and test-retest reliability. The Logical Memory I and Verbal Paired Associates I subtests are the most reliable. Data from three clinical groups (i.e., Alzheimer's disease, chronic alcohol abuse, and schizophrenia) were extracted from the Technical Manual [Psychological Corporation (1997). WAIS-III/WMS-III Technical Manual. San Antonio: Harcourt Brace] for the purpose of calculating reliable change estimates. A table of confidence intervals for test-retest measurement error is provided to help the clinician determine if patients have reliably improved or deteriorated on follow-up testing.
Online Cost Efficient Customer Recognition System for Retail Analytics (2017)

For most physical stores, procuring customer behavior data and client management is di cult yet crucial. For stores, especially luxury stores, who value returning customers the most, identifying customer's identity and past purchase history would significantly improve the sales by personalizing the recommendation. Many chain stores utilize membership card to collect purchase information and change sales strategy accordingly, yet overlooking the vast majority of customers who are not registered members. More detailed statistics including age, gender, customer counts are extremely valuable for adjusting business strategy, which brings the importance of a real-time customer analytic system for retail business. We have developed an accurate, real-time and fully automated system that relies on computer vision and deep learning to identify returning customers and comprehensively filter sales and customer information. To adjust to network bottleneck, limited computation resources, low latency requirement, recognition accuracy and other difficulties, we divided the system into two submodules. The system depends on local computation resources to perform customer detection, tracking and feature extraction. Whereas age and gender estimation, and customer recognition are performed on cloud computing resources to compensate for the limited computation resource at local store and to accommodate multiple stores requirements.
Solid-Phase Synthesis of β-Lactams via the Miller Hydroxamate Approach (2001)

[figure: see text] beta-Lactams were prepared on solid phase starting from serine, threonine, or other beta-hydroxyacids derived from naturally occurring amino acids and a resin bound hydroxylamine. The ring closure was carried out under Mitsunobu conditions. The amino group present on the beta-lactam was used to assemble a short peptide. After a reductive cleavage with Sml2, beta-lactam-containing peptides were obtained.
