Trace Determination of Glycols by HPLC with UV and Electrospray Ionization Mass Spectrometric Detections (1999)

A high-performance liquid chromatography/mass spectrometry (HPLC/MS) method is developed for trace determination of glycols (ethylene glycol, 1,2- and 1,3-propylene glycols, and 2,3-butylene glycol) in water after derivatization with benzoyl chloride. Benzoyl esters of glycols are separated by microcolumn reversed-phase HPLC. Sensitivity and linearity of UV detection at 237 nm is compared with electrospray ionization mass spectrometric (ESI-MS) detection using selected ion monitoring. Limits of detection (LOD) and quantitation (LOQ) for UV detection are 1 and 2 mg/L, respectively. For ESI-MS detection, LOD and LOQ are in the ranges 10-25 and 20-50 μg/L, respectively. LOD obtained by ESI-MS for the determination of glycols is improved by 2-3 orders of magnitude in comparison to previously published methods. The effect of the structure of isomeric glycols on their electrospray mass spectra is discussed. The method has been applied for the determination of glycols in aqueous matrixes containing high concentrations of salts occurring in nuclear waste disposal treatment.
A framework for intuitive collaboration with a mobile manipulator (2017)

In this paper, we present a control strategy that enables intuitive physical human-robot collaboration with mobile manipulators equipped with an omnidirectional base. When interacting with a human operator, intuitiveness of operation is a major concern. To this end, we propose a redundancy solution that allows the mobile base to be fixed when working locally and moves it only when the robot approaches a set of constraints. These constraints include distance to singular poses, minimum of manipulability and distance to objects and angular deviation. Experimental results with a Kuka LWR4 arm mounted on a Neobotix MPO700 mobile base validate the proposed approach.
Photothermal detection for light-scattering material by laser interferometry (1987)

A highly sensitive photothermal scheme is described, in which the photothermally induced refractive index variation is measured by a specially designed interferometry. The setup is very simple and stable in facilitating practical applications. It can be used for light-scattering samples, as well as other state samples. Some experiments for detection of both periodic and nonperiodic photothermal refractive index variation are performed.
RAY ACOUSTICS USING COMPUTER GRAPHICS TECHNOLOGY (2007)

The modeling of room acoustics and simulation of sound wave propagation remain a difficult and computationally expensive task. Two main techniques have evolved, with one focusing on a real physical - wave-oriented - sound propagation, while the other approximates sound waves as rays using raytracing techniques. Due to many advances in computer science, and especially computer graphics over the last decade, interactive 3D sound simulations for complex and dynamic environments are within reach. Inthispaperweanalyzesoundpropagationintermsofacoustic energy and explore the possibilities to map these concepts to radiometry and graphics rendering equations. Although we concentrate on ray-based techniques, we also partially consider wavebased sound propagation effects. The implemented system exploits modern graphics hardware and rendering techniques and is able to efficiently simulate 3D room acoustics, as well as to measure simplified personal HRTFs through acoustic raytracing.
The direct calculation of parametric images from dynamic PET data using maximum-likelihood iterative reconstruction (1997)

The aim of this work is to calculate, directly from projection data, concise images characterizing the spatial and temporal distribution of labelled compounds from dynamic PET data. Conventionally, image reconstruction and the calculation of parametric images are performed sequentially. By combining the two processes, low-noise parametric images are obtained, using a computationally feasible parametric iterative reconstruction (PIR) algorithm. PIR is performed by restricting the pixel time-activity curves to a positive linear sum of predefined time characteristics. The weights in this sum are then calculated directly from the PET projection data, using an iterative algorithm based on a maximum-likelihood iterative algorithm commonly used for tomographic reconstruction. The ability of the algorithm to extract known kinetic components from the raw data is assessed, using data from both a phantom experiment and clinical studies. The calculated parametric images indicate differential kinetic behaviour and have been used to aid in the identification of tissues which exhibit differences in the handling of labelled compounds. These parametric images should be helpful in defining regions of interest with similar functional behaviour, and with FDG Patlak analysis.
[Respiratory failure in disseminated sclerosis]. (2000)

The development and patterns of respiratory failure (RF) are analyzed in 9 patients with disseminated sclerosis (DS). Forced ventilation of the lungs was carried out with consideration for main location of the process. Relationship between patterns of respiratory disorders and neuroanatomy of respiratory regulation is discussed. Involvement of the corticospinal routes is paralleled by dissociation during functional pulmonary tests: spontaneous volumes are less than controlled inspirations. The most severe symptom complexes were observed in RF of predominantly bulbar localization: respiratory anarchy, blocking of airways caused by impaired swallowing, impaired mechanism of coughing reflex, loss of spontaneous respiration, sometimes apnea during sleeping. Involvement of the respiratory nuclei of medullary respiratory center and airways and of the corticonuclear routes of caudal cranial nerves causes the development of a triad of symptoms: glossopharyngolaryngeal paralysis, dysfunction of respiratory nuclei of medulla oblongata, and decreased sensitivity of respiratory center to CO2. Aspiration complications caused by dysphagia are characteristic of bulbar DS. Respiratory function in 5 patients without clinical picture of RF are specially discussed. The authors emphasize unfavorable prognostic significance of signs of extracorporeal obstruction indicating the probability of RF long before its manifestation. Special attention is paid to early diagnosis of symptoms of coming RF when evaluating the status of patients with DS during treatment. Timely use of respiratory resuscitation methods reduces the mortality and ensures a good chance for remissions with recovery of respiratory function, which are characteristic of RF.
DEVELOPMENT OF AN INSTRUMENTED SUBSOILER TO MAP SOIL HARD-PANS AND REAL-TIME CONTROL OF SUBSOILER DEPTH (2001)

An instrumented subsoiler shank was designed and built to measure the soil resistance whilemoving through the soil and for automatic control of the depth of several standard subsoiler shanksmounted on the same frame. Three load cells measure the resultant magnitude and direction of the soilreactions on the shank. Two load cells measure forces perpendicular to the straight shank with aconstant distance between them and another load cell measures the force along the shank. The twoperpendicular load cells are cantilevers with one side mounted to the center of the shanks width andthe other side connected to wheels running inside a hollow beam. The wheels enable the shank to bemoved up and down for different depths with the aid of a hydraulic cylinder. The hydraulic cylinder isconnected to the upper edge of the shank by the lengthwise load cell. The resultant force on the shankis calculated by using the three measured forces, their directions and locations. The instrumented shankwas calibrated and tested in the field. While preliminary in nature, the results indicate that when theshank tip is above a soil hardpan, the soil force on the tip acts upward, and becomes negative when theshank tip is below the hardpan. These results indicate that it may be possible to determine the depth ofthe hardpan by observing when the vertical force on the shank tip passes through zero as the shankdepth is cycled above and below the hardpan.

Sequence of Age-Associated Changes to the Mouse Neuromuscular Junction and the Protective Effects of Voluntary Exercise (2013)

Loss of connections between motor neurons and skeletal muscle fibers contribute to motor impairment in old age, but the sequence of age-associated changes that precede loss of the neuromuscular synapse remains uncertain. Here we determine changes in the size of neuromuscular synapses within the tibialis anterior muscle across the life span of C57BL/6J mice. Immunofluorescence, confocal microscopy and morphometry were used to measure the area occupied by nerve terminal synaptophysin staining and postsynaptic acetylcholine receptors at motor endplates of 2, 14, 19, 22, 25 and 28 month old mice. The key findings were: 1) At middle age (14-months) endplate acetylcholine receptors occupied 238 ± 11 µm(2) and nerve terminal synaptophysin 168 ± 14 µm(2) (mean ± SEM). 2) Between 14-months and 19-months (onset of old age) the area occupied by postsynaptic acetylcholine receptors declined 30%. At many endplates the large acetylcholine receptor plaque became fragmented into multiple smaller acetylcholine receptor clusters. 3) Between 19- and 25-months, the fraction of endplate acetylcholine receptors covered by synaptophysin fell 21%. By 28-months, half of the endplates imaged retained ≤ 50 µm(2) area of synaptophysin staining. 4) Within aged muscles, the degree to which an endplate remained covered by synaptophysin did not depend upon the total area of acetylcholine receptors, nor upon the number of discrete receptor clusters. 5) Voluntary wheel-running exercise, beginning late in middle-age, prevented much of the age-associated loss of nerve terminal synaptophysin. In summary, a decline in the area of endplate acetylcholine receptor clusters at the onset of old age was followed by loss of nerve terminal synaptophysin from the endplate. Voluntary running exercise, begun late in middle age, substantially inhibited the loss of nerve terminal from aging motor endplates.
A cw diode-pumped single-silica fiber comprising 40 cores used as active elements for a high power fiber laser at /spl lambda/=1050 nm (1998)

Summary form only given. We have introduced a multicore fiber used as gain medium for a fiber laser. Nearly 40 monomode cores are fitted into a standard multimode silica glass fiber laser serving as the pump radiation transport fiber. The cores are arranged on an annulus situated next to the border of the fiber. The multimode fiber guides the pump radiation by which the Nd(3+)-doped cores are excited.
Posttreatment Follow-Up of Brucellosis by PCR Assay (1999)

In order to evaluate the usefulness of a peripheral blood PCR assay in the posttreatment follow-up of brucellosis, a cohort of 30 patients was studied by means of blood cultures, rose Bengal, seroagglutination, Coombs' antibrucella tests, and PCR assay at the time of diagnosis, at the end of treatment, and 2, 4, and 6 months later. Of the 29 patients whose PCR assays were initially positive, 28 (96.5%) were negative at the conclusion of the treatment. PCR was positive for the two patients who had relapses and negative for another four who had suspected but unconfirmed relapses. PCR was negative for 98.3% of the follow-up samples from those patients who had a favorable evolution. In conclusion, PCR appears to be a very useful technique, not only for the initial diagnosis of the disease, but also for posttreatment follow-up and the early detection of relapses.

Adaptive OFDM Techniques With One-Bit-Per-Subcarrier Channel-State Feedback (2006)

In the orthogonal frequency-division multiplexing (OFDM) scheme, some subcarriers may be subject to a deep fading. Adaptive techniques can be applied to mitigate this effect if the channel-state information (CSI) is available at the transmitter. In this paper, we study the performance of an OFDM-based communication system whose transmitter has only one bit of CSI per subcarrier, obtained through a low-rate feedback. Three adaptive approaches are considered to exploit such a CSI feedback: adaptive subcarrier selection; adaptive power allocation (APA); and adaptive modulation selection (AMS). Under the conditions of a constant raw data rate and perfect feedback channel, the performance of these approaches are analyzed and compared in terms of raw bit-error rate. It is shown that one-bit CSI feedback can greatly enhance the system performance. Moreover, imperfections of the feedback channel are considered, and their impact on the performance of these techniques is studied. It is shown that by exploiting the knowledge that the feedback channel is imperfect, the performance of the APA and AMS techniques can be substantially improved
Aptasensor based on the selective electrodeposition of protein-linked gold nanoparticles on screen-printed electrodes (2011)

The electrodeposition of DNA-gold nanoparticles previously developed in our group has been used as starting point for the electrodeposition of proteins attached to gold nanoparticles. We have performed a proof of principle by developing a methodology based on the electrodeposition of proteins bound to gold nanoparticles on screen-printed gold microelectrodes using, in a first approach, horseradish peroxide-conjugated gold nanoparticles (gold-HRP). The electrodeposition was achieved at a current positive potential of 800 mV vs. Ag/AgCl and the functionality of the electrodeposited HRP-particles was tested by electrochemical reduction of H(2)O(2). Furthermore, we used this proof of concept in an aptasensor application to detect Leishmania infantum KMP-11. Hence, we have demonstrated not only the functionality of the electrodeposition of proteins bound to gold nanoparticles, but also the utility of the method with the aim of developing a real biosensor containing multiple enzymes or proteins in a multimodular device.
Analgesia and motor activity following administration of THIP into the periaqueductal gray and lateral ventricle of rats (1986)

Abstract Intracerebral microinjections of THIP (4,5,6,7‐tetrahydroisoxazolo[5,4‐c]pyridin‐3‐ol), a GABAergic agonist that produces analgesia when administered systemically, were made to investigate the central sites of action of this agent. Comparisons were also made with intracerebral microinjections of morphine and with systemic administration of each agent. Injections into the ventral lateral periqueductal gray (PAG) produced analgesia on the 55 ° C hot‐plate test following a 2.0 μg dose, but were without effect at the other doses examined (0.5–20.0 μg). In the tail‐flick test, hyperalgesia was seen following the 5.0‐ and 20.0‐μg doses. Motor activity was increased following the 1.0‐, 2.0‐, and 10.0‐μg doses and was accompanied by ipsilateral turning. Injections into the lateral cerebral ventricle (ICV) were without effect at doses of less than 50 μg. No significant effects were observed in the hot‐plate test following 50 μg produced severe ataxia, precluding testing. Following 50 μg, hyperalgesia was seen in the tail‐flick test. THIP at both doses decreased motor activity. The present findings further demonstrate some novel aspects of the pharmacology of THIP and suggest that much of the drug's analgesic activity is produced by interaction with GABAergic receptors outside the PAG and structures easily accessed by ICV administration.
Pilot experimental study on secondary effluent of printing and dyeing wastewater by lignite-coke biological aerated filter (2017)

Biochemical tail water of Printing and Dyeing industry is a typical low load and refractory wastewater. Its COD concentration is between 150-200 mg/L. In this pilot study, the effect of lignite-coke and ceramic filter in BAF treatment of dyeing and biochemical tail water was investigated. By comparison with the laboratory scale test and parameter optimization, lignite-coke filter take obvious advantages on the terms of bleaching and biological bio-film. After several months of continuous lignite-coke BAF pilot operation, the results showed that: when the gas-water volume ratio is 10:1, the hydraulic loading is 0.2m3/m2h,the removal rate of COD beyond 50%, the COD of effluent is below 50 mg/L, the effluent is colorless and it meets requirements of design emissions, it also has a good prospect of engineering application.
Wireless Remote Healthcare Monitoring with Motes (2005)

As the world's aged population grows many governments are looking to remote healthcare monitoring solutions. It is certainly cheaper to keep the elderly and infirm in their own homes rather than in aged-care facilities. However will these remote and wireless monitoring devices deliver what they promise? The medical profession needs strong evidence before they embrace such techniques. In this paper the authors describe the building of a remote monitoring prototype which uses motes, a PDA and a network management application to show that commodity-based hardware may provide one answer to the problem of remotely monitoring people in their own homes. Privacy and security issues associated with such monitoring are also discussed.
Ulcers of the Small Bowel Associated With Stomach-Bypassing Salicylates (1985)

• Ulcers of the small bowel are documented in a patient after intake of salsalate. Rapid clinical and endoscopic improvement occurred on discontinuation of administration of the drug. Endoscopic features suggested the direct effect of a tablet dissolving in the proximal part of the small bowel. To my knowledge, this is the first report of small-bowel ulcerations associated with the newer form of salicylates that bypass the stomach for their absorption. (<i>Arch Intern Med</i>1985;145:1139)
Monoclonal antibody analysis of bovine epithelial keratins. Specific pairs as defined by coexpression. (1986)

We have characterized the keratin proteins of various bovine epithelial tissues by one- and two-dimensional gel electrophoresis, coupled with the immunoblot technique using AE1, AE2, AE3, AE5, CA20, BE14, and 6.11 monoclonal antikeratin antibodies. The results indicate that all known bovine keratins can be divided into two subfamilies. The "acidic" (Type I) subfamily consists of 41-, 43-, 45-, 46-, 50-, 54-, 56-, and 56.5-kDa keratins, all of which have a pI of less than 5.6, and most of them are recognized by our AE1 antibody, whereas the "neutral-to-basic" (Type II) subfamily consists of 55-, 57-, 58-, 62-65-, 66-, and 67-kDa keratins, all of which have a pI of greater than 6.0 and are recognized by our AE3 antibody. Tissue distribution data and cell culture studies show that, within the two subfamilies, keratins with similar "size ranks" form a "pair" as defined by frequent co-expression. Furthermore, within most "keratin pairs," the basic keratin is larger than the acidic one by 8-10 kDa. These results provide further support for the concepts of "keratin subfamilies" and keratin pairs and are consistent with the possibility that the acidic and basic members of at least some keratin pairs may interact specifically during in vivo tonofilament assembly and/or function. Immunoblotting data derived from the use of several monospecific antibodies show that although the size, charge, and pattern of expression of most bovine keratins are similar to those of the human counterparts, there are important exceptions to this rule.

Dispersion equations for vacuum-deposited tilted-columnar biaxial media (2001)

We consider the application of the Bragg-Pippard (BP) equations for form birefringence to a tilted-columnar biaxial thin film with columns of index n(c) and voids of known index n(v). In such a situation the three forward BP equations that express the principal refractive indices n1, n2, and n3 as functions of n(c), n(v), the packing fraction p(c), and the depolarization factors L1, L2, and L3 can be inverted. The procedure described for adding dispersion to the principal indices involves entry to the BP model via the inverted equations, modification of n(c) to allow for dispersion, and then exit from the model via the forward BP equations. We discuss the introduction of composite columns to the model to allow for angular dependence of n(c) and the selection of suitable dispersion functions for bulk tantalum oxide, titanium oxide, and zirconium oxide. Theory and experiment both show that the dispersion of the normal-incidence birefringence Deltan of the thin films is several times larger than the dispersion of the individual principal refractive indices.
Liquid argon Time Projection Chamber (1984)

The principal features of the liquid argon TPC are outlined and the status of development efforts, particularly at UCI, are discussed. Technical problems associated with liquid TPC's are: the liquid must be maintained at a high level of purity to enable long distance drifting of ionization electrons, and the signal size is small due to the absence of practical charge multiplication as found in gas chambers. These problems have been largely resolved in studies using small (1 to 100 l) detectors, thus allowing a realistic consideration of the physics potential of such devices.
