State-of-the-art and future prospects for analogue signal processing-a tutorial (2003)

The authors outline the major trends in analog integrated signal processing. It is noted that A/D and D/A converters are becoming the dominant analog components in major systems, and converters that rely on digital postprocessing and error correction are becoming increasingly popular. Though the relative volume of analog integrated circuits continues to shrink, their importance is actually growing, as higher-speed and more complex digital integrated circuits require more advanced analog interfaces. Present evidence and current trends demonstrate that analog interface circuits will continue to evolve as long as integrated circuit technology continues to advance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Split Open Metal Strip Arrays and Their Application to Resonators (1981)

A new type of reflector which we call split open metal strip array (S-OMSA) is described. This S-OMSA has the principal advantages of efficient reflectivity and wide stop band for strongly piezoelectric substrate materials. We have derived the reflection coefficient of S-OMSA in closed form by applying the image parameter theory to equivalent circuit model. Experiments were done on LiNb03 (128O rot.Y, X-prop.) to verify the theory. Finally, the distortionless resonance characteristics of one- and two port resonators utilizing these S-OMSAs are shown.
One-Year Outcomes and Health Care Utilization in Survivors of Severe Acute Respiratory Syndrome (2007)

Most SARS survivors had good physical recovery from their illness, but some patients and their caregivers reported a significant reduction in mental health 1 year later. Strategies to ameliorate the psychological burden of an epidemic on the patient and family caregiver should be considered as part of future pandemic planning.

Short Chain Fatty Acids (SCFA) Reprogram Gene Expression in Human Malignant Epithelial and Lymphoid Cells (2016)

The effect of short chain fatty acids (SCFAs) on gene expression in human, malignant cell lines was investigated, with a focus on signaling pathways. The commensal microbial flora produce high levels of SCFAs with established physiologic effects in humans. The most abundant SCFA metabolite in the human microflora is n-butyric acid. It is well known to activate endogenous latent Epstein-Barr virus (EBV), that was used as a reference read out system and extended to EBV+ epithelial cancer cell lines. N-butyric acid and its salt induced inflammatory and apoptotic responses in tumor cells of epithelial and lymphoid origin. Epithelial cell migration was inhibited. The n-butyric gene activation was reduced by knock-down of the cell membrane transporters MCT-1 and -4 by siRNA. N-butyric acid show biologically significant effects on several important cellular functions, also with relevance for tumor cell phenotype.

A diary study of information capture in working life (2000)

Despite the increasing number of new devices entering the market allowing the capture or recording of information (whether it be marks on paper, scene, sound or moving images), there has been little study of when and why people want to do these kinds of activities. In an effort to systematically explore design requirements for new kinds of information capture devices, we devised a diary study of 22 individuals in a range of different jobs. The data were used to construct a taxonomy as a framework for design and analysis. Design implications are drawn from the framework and applied to the design of digital cameras and hand held scanners.
Separation of <scp>d</scp> -(+)-Nicotine from a Racemic Mixture by Stereospecific Degradation of the <scp>l</scp> -(−) Isomer with <i>Pseudomonas putida</i> (1980)

Incubation of racemic mixtures of dl-(+/-)-nicotine with Pseudomonas putida resulted in a complete stereoselective degradation of the l-(-) isomer. Unnatural d-(+)-nicotine, which is of pharmacological interest for stereochemical studies of various nicotine-responsive systems, was not affected by the bacterium and was recovered by extraction.
Pump-In Test Correlation Predicts Proppant Placement (1986)

ABSTRACT An empirically derived correlation has been proposed to assist operators in optimizing proppant placement in formations where treating pressures are unpredictable. By observing the pressure decline after an injection test, the average fracturing treatment parameters can be obtained to aid in optimizing the treatment design. A correlation between the pump-in test, the average fracture treatment leakoff rate, and the average treatment pressure increase rate has been established. From these averages, the maximum recommended job size and the critical sand concentration are determined. This technique has proven to be a valuable tool to pinpoint proppant placement difficulties and has assisted in realizing the most effective stimulation treatments.
Synthesis and Application of Dimeric 1,3,5-Triazine Ethers as Hole-Blocking Materials in Electroluminescent Devices (1998)

A series of low molecular weight dimeric 1,3,5-triazine ethers with high glass transition temperatures is synthesized from 2-(4-fluorophenyl)-4,6-diphenyl-1,3,5-triazine and various bisphenols. The thermal and electrochemical properties of these materials are examined using differential scanning calorimetry and cyclic voltammetry, respectively. The glass transition temperatures (Tg) are in the range of 106−144 °C, and all of them have similar thermal stability and show no weight loss up to 380 °C in thermogravimetric measurements. Some of these dimers form stable glasses which do not recrystallize on annealing at or above the Tg. Cyclic voltammetry studies reveal that these compounds undergo reversible reduction between −2.09 and −2.27 V vs ferrocene/ferrocenium as internal standard which correspond to LUMO values between −2.5 and −2.7 eV, respectively. The application of one of these dimeric ethers as a hole-blocking/electron-transport material in organic light-emitting devices is demonstrated.
Embedding Quantum Dot Monolayers in Al<sub>2</sub>O<sub>3</sub> Using Atomic Layer Deposition (2010)

The effect of both thermal and plasma-enhanced atomic layer deposition (ALD) of Al2O3 on the optical properties of Langmuir−Blodgett monolayers of nanocrystals was studied, using CdSe particles as a model system. Thermal ALD yields excellent Al2O3 layers. Using ZnS-coated particles, the layers remain highly luminescent after ALD.
Californium-Based Neutron Radiography for Corrosion Detection in Aircraft (1976)

In support of an overall program aimed at minimizing disassembly and reducing inspection time during aircraft maintenance, a series of projects has been carried out to determine the feasibility of applying neutron radiographic techniques to the nondestructive (NDT) inspection of aircraft and aircraft components. These investigations have clearly demonstrated the superiority of neutron radiography over all other NDT techniques in its ability to detect surface and subsurface corrosion in aircraft structure. This capability is particularly significant where the corrosion is hidden behind thick metallic structural members. The neutron radiographic technique has been applied successfully to detect corrosion in the wing tank of E-2C, C-130, and DC-9 aircraft; rear stabilators of F-4 and F-111 aircraft; aft spar, starboard and port wing, and rudder of the F-8; fuselage skin of the 727; rotary blades of AH-1 and SH-3 helicopters; rotary tail flaps of the UH-2 helicopter; and nose landing gear of A-7 aircraft.

Identification of a 4-(Hydroxymethyl)diarylhydantoin as a Selective Androgen Receptor Modulator (2012)

Structural modification performed on a 4-methyl-4-(4-hydroxyphenyl)hydantoin series is described which resulted in the development of a new series of 4-(hydroxymethyl)diarylhydantoin analogues as potent, partial agonists of the human androgen receptor. This led to the identification of (S)-(-)-4-(4-(hydroxymethyl)-3-methyl-2,5-dioxo-4-phenylimidazolidin-1-yl)-2-(trifluoromethyl)benzonitrile ((S)-(-)-18a, GLPG0492) evaluated in vivo in a classical model of orchidectomized rat. In this model, (-)-18a exhibited anabolic activity on muscle, strongly dissociated from the androgenic activity on prostate after oral dosing. (-)-18a has very good pharmacokinetic properties, including bioavailability in rat (F > 50%), and is currently under evaluation in phase I clinical trials.
A secure collaborative e-diagnostics framework for semiconductor factories (2005)

According to the collaborative diagnostics functions and the interface C requirements suggested in the recent e-diagnostics guidebook of International SEMATECH, this paper proposes a novel e-diagnostics framework, called secure collaborative e-diagnostics framework (SCDF). SCDF is developed based on the technologies of Web services, clustering, and new-generation information security. In addition to providing a variety of e-diagnostics functions, SCDF possesses mechanisms to solve several important issues, such as data isolation for different suppliers, supporting remote diagnoses through multi-party collaboration, diagnostics service and storage failover for assuring system availability and the security measures related to above issues. SCDF provides a possible solution to part of the e-diagnostics interface C and can be applied in semiconductor industry to increase the equipment effectiveness and availability.
Selective step‐growth phenol‐aldehyde polymerization, 1. Synthesis, characterization and X‐ray analysis of linear all‐<i>ortho</i> oligonuclear phenolic compounds (1982)

Abstract The series of dinuclear to nonanuclear all‐ ortho methylene‐bridged oligophenols 2–9 has been synthesized according to a repetitive reaction sequence involving the C‐ ortho regiospecific condensation of appropriate phenoxymagnesium precursors with salicyl alcohol or paraformaldehyde. IR, UV, mass, 1 H and 13 C NMR characteristics of these oligomers are discussed. X‐ray crystal structures of 2, 3, and 4 are also reported.
Adhesion behavior of nylon tire cord/adhesive/rubber systems (1969)

Abstract In static and dynamic adhesion tests, the behavior of nylon tire cord/resorcinol‐formaldehyde–latex (RFL) adhesive/rubber systems was shown to be strongly influenced by the dipping and curing conditions, cord size, and the thickness of rubber layer adjacent to cords. The nature and extent of these effects were different in three types of adhesion tests which differed in stress concentrations they induced at the cord–rubber interface. The influence of stress concentration due to increased cord size was clearly seen in dynamic adhesion tests where the peel strengths of two‐ply cord/rubber samples were measured after flexing them under tension over a pulley for predetermined periods at 230°F. In these tests, the adhesion of samples with large cords weakened more rapidly than that of small cords. The static adhesion level attained with nylons 6 and 66 and other polyamide fibers was strongly dependent on the conditions (time, temperature) under which the RFL adhesive was applied and cured. At any given exposure, adhesion initially increased rapidly with the RFL curing temperature and attained a maximum above a temperature which is characteristic of the polyamide. For nylon 66, optimum adhesion was attained with different combinations of RFL curing temperatures (390–460°F) and times (20–120 sec). Finally the adhesion of nylons 6 and 66 is discussed from thermodynamic considerations based on entropy change.

Boolean decomposition of programmable logic arrays (2003)

The authors present algorithms for Boolean decomposition, which decompose a two-level logic function into a cascade of smaller two-level logic functions, such that the overall area of the resulting logic network is minimized. The algorithms are based on multiple-valued minimization. Given a PLA (programmable logic array), a subset of inputs to the PLA is selected. This selection step incorporates a novel algorithm which selects a set of inputs such that the cardinality of the multiple-valued cover, produced by representing all combinations of these inputs as different values of a single multiple-valued variable, is much smaller than the original binary cover cardinality. A relatively small size for the multiple-valued cover implies that the number of good Boolean factors contained in this subset of inputs are re-encoded to satisfy the constraints given in the multiple-valued cover, thus producing a binary cover for the original PLA whose cardinality equals the multiple-valued cover cardinality.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
What can be learned from human reach-to-grasp movements for the design of robotic hand-eye systems? (2003)

In the field of robot motion control, visual servoing has been proposed as the suitable strategy to cope with imprecise models and calibration errors. Remaining problems such as the necessity of a high rate of visual feedback are deemed to be solvable by the development of real-time vision modules. However, human grasping, which still outshines its robotic counterparts especially with respect to robustness and flexibility, definitely requires only sparse, asynchronous visual feedback. We therefore examined current neuroscientific models for the control of human reach-to-grasp movements with the emphasis lying on the visual control strategy used. From this, we developed a control model that unifies the two robotic strategies look-then-move and visual servoing, thereby compensating the problems that each strategy shows when used alone.

Affinity chromatography purification of angiotensin II receptor using photoactivable biotinylated probes (1990)

We have developed biotinylated photoactivable probes that are suitable for covalent labeling of angiotensin II (AII) receptors and the subsequent purification of covalent complexes through immobilized avidin or streptavidin. One of these probes, biotin-NH(CH2)2SS(CH2)2CO-[Ala1,Phe(4N3)8]AII, which contains a cleavable disulfide bridge in its spacer arm and which displays, in its radioiodinated form, very high affinity for AII receptors (Kd approximately 1 nM), proved to be suitable for indirect affinity chromatography of rat liver receptor with facilitated recovery from avidin gels by use of reducing agents. This constituted the central step of an efficient partial purification scheme involving hydroxylapatite chromatography, streptavidin chromatography, and thiopropyl-Sepharose chromatography. SDS-PAGE analysis and autoradiography established the identity of the purified entity (molecular weight 65K) as the AII receptor. Possible ways of completing purification to homogeneity and extrapolation of the protocols to a preparative scale are discussed, as well as the potential contribution of our new probes to the study of the structural properties of angiotensin receptors.
High‐Dose Thiamine Therapy Counters Dyslipidemia and Advanced Glycation of Plasma Protein in Streptozotocin‐Induced Diabetic Rats (2005)

The streptozotocin-induced (STZ) diabetic rat experimental model of diabetes on insulin maintenance therapy exhibits dyslipidemia, mild thiamine deficiency, and increased plasma protein advanced glycation end products (AGEs). The reversal of thiamine deficiency by high-dose thiamine and S-benzoylthiamine monophosphate (benfotiamine) prevented the development of incipient nephropathy. Recently, we reported that high-dose thiamine (but not benfotiamine) countered diabetic dyslipidemia. To understand further the differences between the effects of thiamine and benfotiamine therapy, we quantified the levels of the AGEs in plasma protein. We found hydroimidazolone AGE residues derived from glyoxal and methylglyoxal, G-H1 and MG-H1, were increased 115% and 68% in STZ diabetic rats, with respect to normal controls, and were normalized by both thiamine and benfotiamine; whereas N-carboxymethyl-lysine (CML) and N-carboxyethyl-lysine (CEL) residues were increased 74% and 118% in STZ diabetic rats and were normalized by thiamine only. The lack of effect of benfotiamine on plasma CML and CEL residue concentrations suggests there may be important precursors of plasma protein CML and CEL residues other than glyoxal and methylglyoxal. These are probably lipid-derived aldehydes.
Design and implementation of an efficient MPEG-4 interactive terminal on embedded devices (2005)

We present an efficient MPEG-4-based interactive player for PDA-like embedded devices in this paper. Our system can receive media from various sources, then decompress and compose them in an object-oriented manner. Embedded devices such as PDA usually have limited computational resources, memory size, power budgets, and multimedia capabilities. To overcome these constraints, two novel mechanisms were introduced, namely adaptive frame rate (AFR) and scene cache graph management (SCGM). Furthermore, a media decoding framework was proposed such that multimedia objects of different formats can be retrieved from different sources and then be decoded. This framework can be extended by add-on components. A semi-pull model was also designed for the synchronization of heterogeneous media objects. Finally, all the key modules were efficiently implemented and optimized. These modules include MPEG-4 video decoder, 2D/3D graphic engine, buffer management, script engine, and streaming service.

The main scope of this contribution is to provide methods for the characterisation and analysis of biomass liquid products from fast pyrolysis process. Relevant methods that are accurate and consistent were identified and recommendations disseminated to companies and institutions in order to harmonise methods and enable comparison of results. Other objectives were to initiate a database containing analytical data on feedstocks and liquid products from fast pyrolysis. The aim was to improve the knowledge of the reasons of quality variations of fuels from fast pyrolysis.
A Mechanistic Study on the Phototoxicity of Atorvastatin: Singlet Oxygen Generation by a Phenanthrene-like Photoproduct (2008)

Atorvastatin calcium (ATV) is one of the most frequently prescribed drugs worldwide. Among the adverse effects observed for this lipid-lowering agent, clinical cases of cutaneous adverse reactions have been reported and associated with photosensitivity disorders. Previous work dealing with ATV photochemistry has shown that exposure to natural sunlight in aqueous solution leads to photoproducts resulting from oxidation of the pyrrole ring and from cyclization to a phenanthrene derivative. Laser flash photolysis of ATV, at both 266 and 308 nm, led to a transient spectrum with two maxima at lambda= 360 and lambda= 580 nm (tau= 41 micro), which was assigned to the primary intermediate of the stilbene-like photocyclization. On the basis of the absence of a triplet-triplet absorption, the role of the parent drug as singlet oxygen photosensitizer can be discarded. By contrast, a stable phenanthrene-like photoproduct would be a good candidate to play this role. Laser flash photolysis of this compound showed a triplet-triplet transient absorption at lambdamax = 460 nm with a lifetime of 26 micro, which was efficiently quenched by oxygen (kq = 3 (+/-0.2) x 10(9) M(-1) s(-1)). Its potential to photosensitize formation of singlet oxygen was confirmed by spin trapping experiments, through conversion of TEMP to the stable free radical TEMPO. The photoreactivity of the phenanthrene-like photoproduct was investigated using Trp as a marker. The disappearance of the amino acid fluorescence (lambdamax = 340 nm) after increasing irradiation times at 355 nm was taken as a measurement of photodynamic oxidation. To confirm the involvement of a type II mechanism, the same experiment was also performed in D2O; this resulted in a significant enhancement of the reaction rate. On the basis of the obtained photophysical and photochemical results, the phototoxicity of atorvastatin can be attributed to singlet oxygen formation with the phenanthrene-like photoproduct as a photosensitizer.
