A new low overhead design for testability of programmable logic arrays (1991)

A new design to reduce the overhead required for fully testable programmable logic arrays (PLAs) is proposed. This design exploits the fact that product lines in a PLA can be rearranged and grouped into few partitions. Then, some extra outputs are added, one per partition, to make the whole PLA testable. Compared with the previous PLA design-for-testability techniques, the algorithm presented is very feasible, and its implementation is straightforward. Furthermore, this algorithm significantly lowers overhead and provides substantially higher fault coverage than some existing schemes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Oral Medium-Dosed Metoclopramide versus Placebo as Highly Effective Antiemetic Prophylaxis in In- and Outpatients on Noncisplatin Chemotherapy (1993)

The antiemetic effect of oral medium-dosed metoclopramide (MCL, 3.5 mg/kg b.w./cycle) and placebo for chemotherapy-induced emesis of a noncisplatin regimen was assessed for inpatients and outpatients in two double-blind placebo-controlled sequential analyses according to Bross (1952). MCL was given in 5 single doses of 0.7 mg/kg b.w. at 0 h (loading) and at 2 h (i.e. start of chemotherapy) and 6, 10 and 14 h (as maintenance doses). Both studies ended after 8 sequential pairs in favor of MCL (2 alpha = 2 beta = 0.05). Major antiemetic protection (< 2 emetic episodes per 26 h) was achieved for 8/8 of inpatients and 7/8 of outpatients (placebo 0/8 and 0/8). Side effects neither required discontinuation of the antiemetic regimen nor additional therapy. The median of MCL plasma levels ranged from 150 to 750 ng/ml and terminal half-lives from 3.9 to 8.9 h.
Normal forms of stiffness and compliance matrices (1987)

A generalized spring associates potential energy with each position and orientation of a rigid body. The stiffness of such a spring can be represented by a 6 × 6 symmetric matrix. This matrix can be brought to a normal form by a particular choice of the coordinate frame. Analogous but independent results hold for compliance matrices. These results, obtained by using a Lie group approach, also extend the concept of the remote center of stiffness to generic generalized springs.
Bootstrapping trust in a trusted platform (2008)

For the last few years, many commodity computers have come equipped with a Trusted Platform Module (TPM). Existing research shows that the TPM can be used to establish trust in the software executing on a computer. However, at present, there is no standard mechanism for establishing trust in the TPM on a particular machine. Indeed, any straightforward approach falls victim to a cuckoo attack. In this work, we propose a formal model for establishing trust in a platform. The model reveals the cuckoo attack problem and suggests potential solutions. Unfortunately, no instantiation of these solutions is fully satisfying, and hence, we pose the development of a fully satisfactory solution as an open question to the community. 1
MAP Estimation, Message Passing, and Perfect Graphs (2012)

Efficiently finding the maximum a posteriori (MAP) configuration of a graphical model is an important problem which is often implemented using message passing algorithms. The optimality of such algorithms is only well established for singly-connected graphs and other limited settings. This article extends the set of graphs where MAP estimation is in P and where message passing recovers the exact solution to so-called perfect graphs. This result leverages recent progress in defining perfect graphs (the strong perfect graph theorem), linear programming relaxations of MAP estimation and recent convergent message passing schemes. The article converts graphical models into nand Markov random fields which are straightforward to relax into linear programs. Therein, integrality can be established in general by testing for graph perfection. This perfection test is performed efficiently using a polynomial time algorithm. Alternatively, known decomposition tools from perfect graph theory may be used to prove perfection for certain families of graphs. Thus, a general graph framework is provided for determining when MAP estimation in any graphical model is in P, has an integral linear programming relaxation and is exactly recoverable by message passing.
Thiol proteinase expression and pathogenicity of Entamoeba histolytica (1989)

Expression of the 56-kilodalton (kDa) neutral thiol proteinase has been shown to correlate with the potential of clinical isolates of Entamoeba histolytica to produce invasive disease. A 56-kDa band was identified by gelatin substrate gel electrophoresis in 10 of 10 isolates from patients with colitis or amebic liver abscesses, but in only 1 of 10 isolates from asymptomatic patients. Pathogenic isolates appear capable of releasing significantly larger quantities of the proteinase, as measured by cleavage of a synthetic peptide substrate, ZRR-AMC (benzyloxy-carbonyl-arginine-arginine-4-amino-7-methylcoumarin). We have also shown that the proteinase is released during the course of clinical invasive amebic disease, as demonstrated by the presence of circulating antibodies detectable by enzyme-linked immunosorbent assay. These studies support the importance of the 56-kDa thiol proteinase in the pathogenesis of invasive amebiasis.
Optokinetic nystagmus in patients with central scotomas in age related macular degeneration (2001)

Abnormalities of OKN gain were noted only in patients with large scotomas. An intact macula is therefore not necessary for the generation of OKN.
Bacterial adhesion onto azidated poly(vinyl chloride) surfaces (2002)

A plasticized poly(vinyl chloride) surface was modified by azidation using sodium azide in the presence of a phase transfer catalyst in aqueous media. Subsequent to azidation, the surface was crosslinked using ultraviolet radiation. Contact angle measurements showed that the surface became hydrophilic on azidation whereas photoirradiation did not have any further effect on the hydrophilicity of the azidated surface. Control, azidated, and photocrosslinked surfaces were exposed to two strains of bacteria commonly implicated in device infection such as Staphylococcus aureus and Escherichia coli. Whereas the control and photocrosslinked surfaces showed no significant difference in bacterial adhesion, the azidated surface showed significantly reduced adhesion to both strains. Data obtained indicate that the presence of an intact azide function on the polymer surface is responsible for the reduced bacterial adherence and the surface hydrophobicity/hydrophilicity did not exert any effect in the present case. Although azides are known to be effective only against Gram-negative species, surprising was the observation that the azidated polymer surface was equally effective against a Gram-positive species such as S. aureus. Because sodium azide is routinely used as a preservative to prevent bacterial and fungal growth in many microbiology reagents and diagnostic kits, covalent binding of the azide onto a polymer surface or synthesizing azide containing polymers may be an interesting method to investigate in tackling the problem of bacterial adhesion and colonization of medical devices.
Simulation of Real-Time Frequency Estimators for Pulsed Doppler Systems (1986)

Four time-domain oriented, real-time frequency estimators, based on the detection of phase, zero-crossings, instantaneous frequency or autocorrelation, were simulated on a digital computer and subjected to computer generated Doppler signals, enabling the investigation of the influence of spectral shape, filtering, frequency shift, noise and quantitation. Three estimators, the autocorrelator as well as the instantaneous frequency detector and the autocorrelator, both with extended frequency range, appeared to be very accurate. They exhibit a bias in the estimator output of less than 2 percent over a wide frequency range, the former up to nearly the Nyquist frequency, the latter two beyond, even for skew spectra and under poor signal conditions regarding bandwidth and noise.
Ultrawideband Radio Design: The Promise of High-Speed, Short-Range Wireless Connectivity (2004)

The paper provides a tutorial overview of ultrawideband (UWB) radio technology for high-speed wireless connectivity. Subsequent to establishing a historical and technological context, it describes the new impetus for UWB systems development and standardization resulting from the FCC's recent decision to permit unlicensed operation in the 3.1-10.6 GHz band subject to modified Part 15 rules and indicates the potential new applications that may result. Thereafter, the paper provides a system architect's perspectives on the various issues and challenges involved in the design of link layer subsystems. Specifically, we outline current developments in UWB system design concepts that are oriented to high-speed applications and describe some of the design tradeoffs involved.
Pasteurized Milk as a Vehicle of Infection in an Outbreak of Listeriosis (1985)

Between June 30th and August 30th, 1983, 49 patients in Massachusetts acquired listeriosis. Seven cases occurred in fetuses or infants and 42 in immunosuppressed adults; 14 patients (29 per cent) died. Of 40 Listeria monocytogenes isolates available for testing, 32 were serotype 4b. Two case-control studies, one matching for neighborhood of residence and the other for underlying disease, revealed that the illness was strongly associated with drinking a specific brand of pasteurized whole or 2 per cent milk (odds ratio = 9, P less than 0.01 for the neighborhood-matched study; odds ratio = 11.5, P less than 0.001 for the illness-matched study). The association with milk was further substantiated by four additional analyses that suggested the presence of a dose-response effect, demonstrated a protective effect of skim milk, associated cases with the same product in an independent study in another state, and linked a specific phage type with the disease associated with milk. The milk associated with disease came from a group of farms on which listeriosis in dairy cows was known to have occurred at the time of the outbreak. Multiple serotypes of L. monocytogenes were isolated from raw milk obtained from these farms after the outbreak. At the plant where the milk was processed, inspections revealed no evidence of improper pasteurization. These results support the hypothesis that human listeriosis can be a foodborne disease and raise questions about the ability of pasteurization to eradicate a large inoculum of L. monocytogenes from contaminated raw milk.
Toggle-masking for test-per-scan VLSI circuits (2004)

This paper presents a novel toggle-masking technique that eliminates the switching activity in a circuit under test (CUT) during the scan-shifting in a test-per-scan test. Conventional scannable D flip-flops (DFFs) are modified to ensure that CUT inputs remain unchanged until an entire test vector is loaded, significantly reducing the power dissipation in the CUT. Our experiments on ISCAS85/89 benchmark circuits show that the proposed technique offers an average of 47% savings in average power compared to previous work (S. Gerstendorfer and H. Wunderlich, Proc. Int. Test Conf., pp. 77-84, 1999), and an average of 99% savings in average power and 8% savings in peak power with respect to test-per-scan circuits with conventional DFFs.

In-vivo characterization of optical properties of pigmented skin lesions including melanoma using oblique incidence diffuse reflectance spectrometry (2011)

In this letter, we report the first use of oblique incidence diffuse reflectance spectrometry to conduct in-vivo measurements of optical properties of three different types of pigmented skin lesions, including melanoma, dysplastic, and common nevi. Both absorption and reduced scattering coefficient spectra were estimated from the spatially resolved diffuse reflectance within the wavelength range of 455-765 nm for 144 pigmented skin lesions including 16 melanomas. The absorption and reduced scattering spectra were found to change with the malignancy of the skin lesions, which were generally higher for the malignant cases than the benign ones. Based on the measurement results, the physiological origin leading to the change of the absorption and scattering properties is also discussed.
Polyalphaolefins: Meeting the challenge for high-performance lubrication (1994)

During Drosophila melanogaster dorsal closure, lateral sheets of embryonic epidermis assemble an actomyosin cable at their leading edge and migrate dorsally over the amnioserosa, converging at the dorsal midline. We show that disappearance of the homophilic cell adhesion molecule Echinoid (Ed) from the amnioserosa just before dorsal closure eliminates homophilic interactions with the adjacent dorsal-most epidermal (DME) cells, which comprise the leading edge. The resulting planar polarized distribution of Ed in the DME cells is essential for the localized accumulation of actin regulators and for actomyosin cable formation at the leading edge and for the polarized localization of the scaffolding protein Bazooka/PAR-3. DME cells with uniform Ed fail to assemble a cable and protrude dorsally, suggesting that the cable restricts dorsal migration. The planar polarized distribution of Ed in the DME cells thus provides a spatial cue that polarizes the DME cell actin cytoskeleton, defining the epidermal leading edge and establishing its contractile properties.
Optimization of steady‐state pulsed CEST imaging for amide proton transfer at 3T MRI (2019)

We optimized the SS-pCEST imaging method with SSFP to maximize the amide proton transfer effects. In addition, our analysis showed the SSFP sequence was more efficient than the spoiled gradient echo sequence for SS-pCEST imaging.
Rate-compatible QC-LDPC codes design based on EXIT chart analysis (2012)

This paper proposes a "column extension" design method for rate-compatible quasi-cyclic (QC) low-density parity-check (LDPC) codes, which can provide efficient multi-rate coding schemes for communication systems with flexible spectrum efficiency. The optimization of degree distributions among multiple code rates makes the designed QC-LDPC codes achieve excellent performance at each code rate, while the nested parity-check matrix structure of the designed codes facilitates the implementation of multi-rate encoder/decoder and offers the advantage of low-complexity. A comparison with the multi-rate LDPC codes in DVB-S2 specification is addressed. Extrinsic information transfer (EXIT) chart analysis predicts the superiorities of the optimized degree distributions in E <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">b</sub> /N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> thresholds, and the bit error rate (BER) simulation results show that the designed codes perform 0.03-0.1 dB better than the DVB-S2 64K codes at each typical code rate, with even shorter code length.
Immunosignatures can predict vaccine efficacy (2013)

The development of new vaccines would be greatly facilitated by having effective methods to predict vaccine performance. Such methods could also be helpful in monitoring individual vaccine responses to existing vaccines. We have developed "immunosignaturing" as a simple, comprehensive, chip-based method to display the antibody diversity in an individual on peptide arrays. Here we examined whether this technology could be used to develop correlates for predicting vaccine effectiveness. By using a mouse influenza infection, we show that the immunosignaturing of a natural infection can be used to discriminate a protective from nonprotective vaccine. Further, we demonstrate that an immunosignature can determine which mice receiving the same vaccine will survive. Finally, we show that the peptides comprising the correlate signatures of protection can be used to identify possible epitopes in the influenza virus proteome that are correlates of protection.

Organosilane micellization for direct encapsulation of hydrophobic quantum dots into silica beads with highly preserved fluorescence (2012)

Effective silica coating on hydrophobic quantum dots (QDs) was achieved by ultrasonic fragmentation of lipophilic silane-QDs precusor into water-soluble micelles and subsequent silicate deposition. This method allowed high retention of QD fluorescent properties and an easy scaling over the size and loading amount of silica beads.
Potential errors in pulse oximetry (1991)

The published studies of pulse oximeter performance under conditions of normal, high and low saturation, exercise, poor signal quality and cardiac arrhythmia are reviewed. Most pulse oximeters have an absolute mean error of less than 2% at normal saturation and perfusion; two-thirds have a standard deviation (SD) of less than 2%, and the remainder an SD of less than 3%. Some pulse oximeters tend to read 100% with fractional saturations of 97-98%. Pulse oximeters may be suitable hyperoxic alarms for neonates if the alarm limit chosen is directly validated for each device. Pulse oximeters are poorly calibrated at low saturations and are generally less accurate and less precise than at normal saturations; nearly 30% of 244 values reviewed were in error by more than 5% at saturations of less than 80%. Ear, nose and forehead probes respond more rapidly to rapid desaturation than finger probes, but are generally less accurate and less precise. Ear oximetry may be inaccurate during exercise. Low signal quality can result in failure to present a saturation reading, but data given with low signal quality warning messages are generally no less accurate than those without. Cardiac arrhythmias do not decrease accuracy of pulse oximeters so long as saturation readings are steady.
A 480 mW 2.6 GS/s 10b Time-Interleaved ADC With 48.5 dB SNDR up to Nyquist in 65 nm CMOS (2011)

This paper presents a 64-times interleaved 2.6 GS/s 10b successive-approximation-register (SAR) ADC in 65 nm CMOS. The ADC combines interleaving hierarchy with an open-loop buffer array operated in feedforward-sampling and feedback-SAR mode. The sampling front-end consists of four interleaved T/Hs at 650 MS/s that are optimized for timing accuracy and sampling linearity, while the back-end consists of four ADC arrays, each consisting of 16 10b current-mode non-binary SAR ADCs. The interleaving hierarchy allows for many ADCs to be used per T/H and eliminates distortion stemming from open loop buffers interfacing between the front-end and back-end. Startup on-chip calibration deals with offset and gain mismatches as well as DAC linearity. Measurements show that the prototype ADC achieves an SNDR of 48.5 dB and a THD of less than 58 dB at Nyquist with an input signal of 1.4 . An estimated sampling clock skew spread of 400 fs is achieved by careful design and layout. Up to 4 GHz an SNR of more than 49 dB has been measured, enabled by the less than 110 fs rms clock jitter. The ADC consumes 480 mW from 1.2/1.3/1.6 V supplies and occupies an area of 5.1 mm.
