The role of charge transfer complexes in the photodegradation of polyolefins (1997)

Abstract Addition of HALS‐stabilisers, the cut‐off wavelength of the light source, the temperature and the oxygen pressure have an influence on the UV‐degradation mechanism of polyolefins. All these parameters influences the conversion of oxygen into polymeric carbonyls. The results are explained assuming that the initiation of the UV‐degradation of pololefins is due to substrate‐oxygen charge transfer complexes (CTCs).
Temperature Effects in Cyanolysis Using Elemental Sulfur (1996)

As part of our studies directed at new treatments for cyanide poisoning we examined the effect of temperature on both the non-catalyzed and the albumin-catalyzed reactions of cyanide with a colloidal suspension of elemental sulfur (CSES). Using saturated sulfur solutions prepared in two solvents, pyridine (PY) and methyl cellosolve (MC), the reactions were studied at 15.0, 25.0, 30.0 and 37.5°C. For all the cyanolysis reactions (non-catalyzed and albumin-catalyzed) there is an enhancement of reaction rate when the organic solvent for the sulfur is MC. Irrespective of the solvent for the CSES, the non-catalyzed reactions gave linear Arrhenius plots (PY, correlation coefficient = 0.998; MC, correlation coefficient = 0.997). In each case the entropy of activation was positive (14.1 cal K−1 mol−1 for PY and 56.4 cal K−1 mol−1 for MC). In contrast with these results the albumin-catalyzed reactions generated non-linear Arrhenius plots and negative entropies of activation. Non-linear plots were observed with the three albumins studied: human serum albumin, heat-shock bovine serum albumin and fatty acid-free bovine serum albumin. The non-linear plots are the result of a more complex reaction sequence than a simple cyanolysis reaction.
Flow Cytometric Measurement of Blood Cells with BCR-ABL1 Fusion Protein in Chronic Myeloid Leukemia (2017)

Abstract Chronic myeloid leukemia (CML) is characterized in the majority of cases by a t(9;22)(q34;q11) translocation, also called the Philadelphia chromosome, giving rise to the BCR-ABL1 fusion protein. Current treatment with tyrosine kinase inhibitors is directed against the constitutively active ABL1 domain of the fusion protein, and minimal residual disease (MRD) after therapy is monitored by real-time quantitative PCR (RQ-PCR) of the fusion transcript. Here, we describe a novel approach to detect and enumerate cells positive for the BCR-ABL1 fusion protein by combining the in situ proximity ligation assay with flow cytometry as readout (PLA-flow). By targeting of the BCR and ABL1 parts of the fusion protein with one antibody each, and creating strong fluorescent signals through rolling circle amplification, PLA-flow allowed sensitive detection of cells positive for the BCR-ABL1 fusion at frequencies as low as one in 10,000. Importantly, the flow cytometric results correlated strongly to those of RQ-PCR, both in diagnostic testing and for MRD measurements over time. In summary, we believe this flow cytometry-based method can serve as an attractive approach for routine measurement of cells harboring BCR-ABL1 fusions, also allowing simultaneously assessment of other cell surface markers as well as sensitive longitudinal follow-up.
The Sad1-UNC-84 homology domain in Mps3 interacts with Mps2 to connect the spindle pole body with the nuclear envelope (2006)

The spindle pole body (SPB) is the sole site of microtubule nucleation in Saccharomyces cerevisiae; yet, details of its assembly are poorly understood. Integral membrane proteins including Mps2 anchor the soluble core SPB in the nuclear envelope. Adjacent to the core SPB is a membrane-associated SPB substructure known as the half-bridge, where SPB duplication and microtubule nucleation during G1 occurs. We found that the half-bridge component Mps3 is the budding yeast member of the SUN protein family (Sad1-UNC-84 homology) and provide evidence that it interacts with the Mps2 C terminus to tether the half-bridge to the core SPB. Mutants in the Mps3 SUN domain or Mps2 C terminus have SPB duplication and karyogamy defects that are consistent with the aberrant half-bridge structures we observe cytologically. The interaction between the Mps3 SUN domain and Mps2 C terminus is the first biochemical link known to connect the half-bridge with the core SPB. Association with Mps3 also defines a novel function for Mps2 during SPB duplication.
Hexose metabolism in pancreatic islets. Glucose-induced and Ca2+-dependent activation of FAD-glycerophosphate dehydrogenase (1991)

A rise in extracellular D-glucose concentration causes in pancreatic islets a preferential stimulation of aerobic, relative to total, glycolysis. The possible participation in such a phenomenon of a glucose-induced and Ca(2+)-dependent activation of FAD-glycerophosphate dehydrogenase was investigated. In islet homogenates, the activity of the mitochondrial and Ca(2+)-responsive FAD-glycerophosphate dehydrogenase was about two orders of magnitude lower than that of the cytosolic and Ca(2+)-insensitive NAD-glycerophosphate dehydrogenase. In islet mitochondria, Ca2+ increased the affinity of the FAD-glycerophosphate dehydrogenase for L-glycerol 3-phosphate, but did not affect the maximal reaction velocity. In the presence of 0.1 mM-L-glycerol 3-phosphate, the Ka for Ca2+ was close to 0.1 microM. When intact islets were preincubated in the presence of both D-glucose and Ca2+, the activity of FAD-glycerophosphate dehydrogenase measured in intact mitochondria incubated in the presence of 1.2 microM-Ca2+ was higher than that recorded under the same conditions in islets preincubated in the absence of D-glucose and/or Ca2+. These findings support the view that, in islets exposed to a high concentration of D-glucose, a Ca(2+)-induced activation of mitochondrial FAD-glycerophosphate dehydrogenase favours the transfer of reducing equivalents by the glycerol phosphate shuttle, and hence accounts, in part at least, for the preferential stimulation of aerobic glycolysis.
Inhibitory Effects of the New Bombesin Receptor Antagonist RC-3095 on the Luteinizing Hormone Release in Rats (1992)

The effects of bombesin receptor antagonist RC-3095 and gastrin-releasing peptide [GRP (14-27)] on basal luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone levels, as well as on the release of LH and FSH in response to LH-releasing hormone, were studied in normal and castrated male rats. We also examined the release of LH and FSH after intracerebroventricular injection of RC-3095 under different types of anesthesia (urethane, sodium pentobarbital, Metofane). Following injection of 10 micrograms RC-3095 into the lateral brain ventricle, serum LH levels were rapidly and significantly (p < 0.001) lowered. This effect lasted for at least 60 min and was not affected by the type of anesthetic used. Serum FSH levels were not affected by intracerebroventricular administration of RC-3095 or GRP (14-27), indicating different central control mechanisms between LH and FSH release. The suppressive effect of RC-3095 on LH release could be completely prevented by prior intracerebroventricular administration of GRP (14-27) at a dose of 1 micrograms, but intravenous administration of either peptide RC-3095 or GRP (14-27) did not change the basal levels of LH, FSH, and testosterone. The pituitary LH response to LH-releasing hormone was also not modified by intravenous administration of RC-3095. These results indicate that bombesin-like peptides might be involved in control of LH release from the pituitary by an action on the CNS which is mediated by specific bombesin receptors.

Fast proxy delivery of multiple streaming sessions in shared running buffers (2005)

With the falling price of memory, an increasing number of multimedia servers and proxies are now equipped with a large memory space. Caching media objects in the memory of a proxy helps to reduce the network traffic, the disk I/O bandwidth requirement, and the data delivery latency. The running buffer approach and its alternatives are representative techniques to caching streaming data in the memory. There are two limits in the existing techniques. First, although multiple running buffers for the same media object co-exist in a given processing period, data sharing among multiple buffers is not considered. Second, user access patterns are not insightfully considered in the buffer management. In this paper, we propose two techniques based on shared running buffers in the proxy to address these limits. Considering user access patterns and characteristics of the requested media objects, our techniques adaptively allocate memory buffers to fully utilize the currently buffered data of streaming sessions, with the aim to reduce both the server load and the network traffic. Experimentally comparing with several existing techniques, we show that the proposed techniques achieve significant performance improvement by effectively using the shared running buffers.
Top of worlds (2012)

We propose a method for improving motivation to participate in sensing services by presenting rankings in multidimensional hierarchical sets. We call this method Top of Worlds. Because previously proposed methods only rank a user among all other users, many have little chance of being ranked in the top group, resulting in little motivation to continue. Top of Worlds creates many sets with varying granularity to increase the chance of many users being ranked in the top group and presents these rankings in those sets. Through an experiment, we partially confirmed the validity of Top of Worlds.
THE EFFECT OF FLAMING OF TAPS BEFORE SAMPLING ON THE BACTERIOLOGICAL EXAMINATION OF FARM WATER SUPPLIES (1954)

Summary: The flaming of taps before sampling caused no significant differences in the most probable numbers of coli‐aerogenes organisms or Bact. coli in water samples, or in the colony counts at 37 or 22°, though there was a tendency for the bacterial content to be lowered.
Catabolite repression in Lactobacillus casei ATCC 393 is mediated by CcpA (1997)

The chromosomal ccpA gene from Lactobacillus casei ATCC 393 has been cloned and sequenced. It encodes the CcpA protein, a central catabolite regulator belonging to the LacI-GalR family of bacterial repressors, and shows 54% identity with CcpA proteins from Bacillus subtilis and Bacillus megaterium. The L. casei ccpA gene was able to complement a B. subtilis ccpA mutant. An L. casei ccpA mutant showed increased doubling times and a relief of the catabolite repression of some enzymatic activities, such as N-acetylglucosaminidase and phospho-beta-galactosidase. Detailed analysis of CcpA activity was performed by using the promoter region of the L. casei chromosomal lacTEGF operon which is subject to catabolite repression and contains a catabolite responsive element (cre) consensus sequence. Deletion of this cre site or the presence of the ccpA mutation abolished the catabolite repression of a lacp::gusA fusion. These data support the role of CcpA as a common regulatory element mediating catabolite repression in low-GC-content gram-positive bacteria.
Recruitment (1987)

People are the most important component of any firm’s ability to cope with the increasing demands of a complex business environment; high calibre staff will overcome difficulties and seize opportunities that their less able colleagues fail to discern. From that general statement the conclusion that the firm should recruit the most able individuals for any given task is inescapable. But in order to do this, the limitations of the job within the overall management structure will have to be carefully studied since it is pointless to recruit individuals who are too highly qualified or able for the job that the organisation wants to fill; they will become discontented and leave.
Sensor Networks for Lighting Control (2009)

This paper summarizes results from a research program investigating the development and application of sensor networks to lighting control and building energy management. Commercial, industrial and residential buildings often incorporate systems used to determine occupancy, however, current sensor technology and control algorithms limit the effectiveness of these devices in both energy management and security systems. These systems rely on single measurement points to detect occupancy, and as a result there can be significant uncertainty associated with the measurement of occupancy. Long time delay and high detector sensitivity settings compensate for this uncertainty, and as a result, more energy is wasted than if occupancy were more accurately measured. A network of inexpensive occupancy sensors provides a more accurate, reliable and robust occupancy measurement, and is potentially more economical in terms of initial investment and operating costs, than single-point detection systems. We show that it may be possible with a sensor network to reduce the operating time of occupancy-based building systems by an extra 20% (compared to current systems) and that the simple payback periods associated with wireless sensor networks applied in generic small and large commercial buildings may be less than two years.
Timing of Death and Myocardial Infarction in Patients with Non‐ST Elevation Acute Coronary Syndromes: Insights From Randomized Clinical Trials (2007)

Our study provides important insights into the timing of adverse events and suggests that the substantial proportion of patients suffer subsequent adverse events after their index NSTE ACS. Thus, these data call for continuous surveillance for these events and efforts beyond the acute phase at increasing adherence to evidence-based therapies to improve the outcomes of these patients.
Parallel two-step phase-shifting digital holograph microscopy based on a grating pair (2011)

An optical configuration for parallel two-step phase-shifting digital holographic microscopy (DHM) based on a grating pair is proposed for the purpose of real-time phase microscopy. Orthogonally circularly polarized object and reference waves are diffracted twice by a pair of gratings, and two parallel copies for each beams come into being. Combined with polarization elements, parallel two-step phase-shifting holograms are obtained. Based on the proposed configuration, two schemes of DHM, i.e., slightly off-axis and on-axis DHM, have been implemented. The slightly off-axis DHM suppresses the dc term by subtracting the two phase-shifting holograms from each other, thus the requirement on the off-axis angle and sampling power of the CCD camera is reduced greatly. The on-axis DHM has the least requirement on the resolving power of the CCD camera, while it requires that the reference wave is premeasured and its intensity is no less than 2 times the maximal intensity of the object wave.
Radiation Resistant HTS Quadrupoles for RIA (2005)

Extremely high radiation, levels with accumulated doses comparable to those in nuclear reactors than in accelerators, and very high heat loads (/spl sim/15 kW) make the quadrupole magnets in the fragment separator one of the most challenging elements of the proposed Rare Isotope Accelerator (RIA). Removing large heat loads, protecting the superconducting coils against quenching, the long term survivability of magnet components, and in particular, insulation that can retain its functionality in such a harsh environment, are the major challenges associated with such magnets. A magnet design based on commercially available high temperature superconductor (HTS) and stainless steel tape insulation has been developed. HTS will efficiently remove these large heat loads and stainless steel can tolerate these large radiation doses. Construction of a model magnet has been started with several coils already built and tested. This paper presents the basic magnet design, results of the coil tests, the status and the future plans. In addition, preliminary results of radiation calculations are also presented.
Experimental Demonstration of Reflection and Refraction of Optical Pulses from Temporal Boundaries (2016)

We experimentally implement the proposal of Plansinis et al.[PRL 115, 183910 (2015)] using slow light in Rubidium vapor. Time-dependent frequency shifts on probe pulses behave like angles in the analogous spatial reflection and refraction from classical optics.
Vertically integrated circuits: Example of an application to an x-ray detector (2014)

Replacing planar circuits with vertically integrated ones allows to increment circuit functionalities on a given silicon area, while avoiding some of the problems associated with aggressively scaled technology nodes. This is particularly true for applications likely to subject circuits to high doses of ionizing radiation (such of x-ray detectors to be used in synchrotron rings and Free Electron Lasers), since the degradation mechanisms of some of the innovative materials to be used in most recent nodes have not been fully characterized yet. In this paper, an evolution is presented for the readout ASIC of a pixelated x-ray detector to be used for such applications. The readout circuit is distributed in a stack of two vertically interconnected tiers, thus doubling the circuitry resident in each pixel without increasing the pixel pitch (and thus compromising spatial resolution of the detector). A first prototype has been designed and manufactured, using a commercial 130 nm CMOS technology. Design issues are discussed, along with preliminary characterization results.
Power auxiliary resonant commutated pole converters for utility applications (2002)

The auxiliary resonant commutated pole converter has the ability to improve the performance of the hard switched converter for utility applications at the distribution power level. Low complexity and modularity are achieved by using integrated active snubber modules with conventional IGBT modules. An improvement in IGBT switching loss of approximately 40% is obtained and switching frequencies of up to 5 kHz are reached at maximum current and voltage ratings, while unwanted high circuit transients are reduced, causing a reduction of at least 10 dB in high frequency currents, voltages and fields generated by the conventional hard switched converter. The paper presents the development of a three phase resonant converter prototype and illustrates its application as a power quality compensator at 100 kVA and discusses the implementation of the same technology at the MVA power levels.
Distributed kalman filtering for noisy consensus networks with time delays (2012)

This work focuses on consensus networks consisting of a group of mobile agents in the presence of noise and time delays. Due to noise, exact consensus is never reached. Hence, we propose fully distributed and local Kalman filters that filter only a subset of all system states while maintaining a filter quality close to a global Kalman filter. Feasibility is guaranteed by communicating measurements through the network, introducing time delays. The overall system stability is analyzed. Simulations demonstrate the performance of the proposed distributed filters.

[Invited papers] Comparing Approaches to Interactive Lifelog Search at the Lifelog Search Challenge (LSC2018) (2019)

The Lifelog Search Challenge (LSC) is an international content retrieval competition that evaluates search for personal lifelog data. At the LSC, content-based search is performed over a multi-modal dataset, continuously recorded by a lifelogger over 27 days, consisting of multimedia content, biometric data, human activity data, and information activities data. In this work, we report on the first LSC that took place in Yokohama, Japan in 2018 as a special workshop at ACM International Conference on Multimedia Retrieval 2018 (ICMR 2018). We describe the general idea of this challenge, summarise the participating search systems as well as the evaluation procedure, and analyse the search performance of the teams in various aspects. We try to identify reasons why some systems performed better than others and provide an outlook as well as open issues for upcoming iterations of the challenge.
The Characteristics and Fabrications of the Optical Fiber Coupler for ADM or WDM Optical Communications (1999)

We report the characteristics of optical fiber coupler that was fabricated with different fabricating conditions. In preparing the optical fiber coupler made of QPS-QFBC-21-R fiber, we found that optimal torch flame temperature was 1622, and the optimal elongation speed was 20. Excess loss of the fabricated 50% coupler with above conditions was 0.29dB and that of the fabricated 100% coupler with above conditions was 0.51dB. Insertion loss of the fabricated 50% coupler with above conditions was 3.31dB and that of the fabricated 100% coupler with above conditions was 1.0dB. When the fiber bragg grating was fabricated in the coupling region of optical fiber coupler, we knew that reflectivity and transmittivity was 46%, 54%, respectively at bragg wavelength. These low reflectivity and transmittivity were due to the decreased Ge concentration in the coupling region of the coupler.
