Correction of Single Photon or Particle Timing Measurements for Multiparticle Events (1972)

In particle time of flight or photon timing measurements, usually only the first event can be timed. An algorithm is derived which uses the measured distribution of first arrivals and a measured or assumed distribution of events per sweep to generate the desired distribution of all arrivals. The theory is shown to work at all values of the average count rate per sweep by comparison with computer simulated experiments. It is found that the optimum recovery of information at long times occurs at an average count rate per sweep of 1.
Floating negative-impedance converters (1972)

Two floating negative-impedance converters (FNICs) using operational amplifers are proposed. Each circuit uses a common-grounded power supply and can simulate floating negative elements. The stability properties of the two circuits are examined. In line with other published grounded NICs, one of the ports is found to be short-circuit stable and the other open-circuit stable. The application of the FNICs for the design of two-directional constant-resistance amplifiers is considered.

OFDM PAPR Reduction Based on Nonlinear Functions without BER Degradation and Out-of-Band Emission (2009)

Peak-to-average power ratio (PAPR) reduction techniques based on nonlinear functions (clipping, companding techniques, etc) are the most straightforward PAPR reduction methods. These techniques reduce the PAPR at the cost of generating distortions. In this paper, we prove basing on Bussgang theorem that in context of PAPR reduction techniques using nonlinear functions, the uncorrelated component resulting in nonlinear process of the input signal amplitude is the component for PAPR reduction. Based on this result, we propose to reduce PAPR of multicarrier systems by exploiting the unused subcarriers embedded in their spectrums to carry the component for PAPR reduction without BER degradation and without Out-Of-Band (OOB) emission. Later in the paper, the classical clipping function is used to reduce the PAPR of the wireless local area networks (WLAN) system based on IEEE 802.11 a/g standard without BER degradation and OOB emission.
Characteristics of Water Vapor Adsorption and Desorption in Thermo-Sensitive Mesoporous Silica Gel/Polymer Gel (2008)

2 nm 付近に狭い細孔径分布を有するメソポーラスシリカゲルを溶媒揮発法により合成した．合成シリカゲルC12の細孔径は2.0 nm 以下であり，C18の細孔径は2.2 nmである．これらの合成シリカゲルの水蒸気に対する吸脱着の温度依存性を明らかにするとともに，有効吸着容量の評価を行った．C12およびC18合成シリカゲルは温度依存性のあるS字型の吸着等温線を示した．C12の水蒸気に対する有効吸着容量は，相対湿度Φ=0.29（303 K）とΦ=0.21（333 K）の範囲で0.11 kg-H2O/kg-silica gel という大きな値が得られた．C18合成シリカゲルに感温性高分子（NIPA: N-isopropylacrylamide）を導入したC18メソポーラスシリカゲル／高分子ゲルは，感温性高分子の性質が相転移温度（Tp=306 K）前後で親水性から疎水性へと不連続に変化するために，水蒸気の吸着量がドラスティックな変化を示すことがわかった．この感温性を有するメソポーラスシリカゲル／高分子ゲルの特性をデシカント空調システムに適用することにより，再生操作温度の一層の引き下げが期待される．

Measurement of activin in biological fluids by radioimmunoassay, utilizing dissociating agents to remove the interference of follistatin (1996)

Activin, a dimer of the beta-subunits of inhibin, is a member of the transforming growth factor beta (TGF-beta) superfamily of growth factors and has a widespread range of actions in a variety of tissues. The investigation of the physiology of activin action has been facilitated in recent years by the availability of immunoassays in addition to bioassays. Follistatin has been shown to bind to activin with a high affinity and therefore interferes in both radioimmunoassays and enzyme-linked immunosorbent assays (ELISAs). In this study we examined the effect of various surfactants and 1.4-dioxane on the measurement of activin in the presence of follistatin by radioimmunoassay. The addition of a combination of sodium deoxycholate. Tween 20 and sodium dodecyl sulphate removed the interference of follistatin in the radioimmunoassay. The measured content of activin in male rat serum, human male serum, human female serum and bovine follicular fluid rose from 3.29 to 4.15, < 0.48 to 2.87, 2.42 to 4.17 and 30.9 to 85.6 ng/ml, respectively, when assayed in the presence of the dissociating reagents. It was unclear whether the altered potencies were due to a dissociation of the follistatin/activin complex rather than the exposure of the epitope on activin recognized by the antiserum. Serum concentrations of activin were lower than those found in testicular cytosols, and after castration no change in serum activin levels was observed, suggesting that the testis does not contribute significantly to circulating activin levels. The use of the dissociating reagents in the radioimmunoassay will enable studies to be carried out that more accurately measure the activin content of various biological fluids, and thus lead to a greater understanding of the physiology of this growth factor.
Nonphysiological Left Heart AV Intervals as a Result of DDD and AAI “Physiological” Pacing (1991)

DDD and AAI pacemakers are considered physiological, since they preserve atrioventricular (AV) synchrony. Artificial pacing, however, is performed largely from right heart chambers, causing aberrant depolarization pathways. Pacing at the right atrial appendage (RAP) is known to delay left atrial contraction due to interatrial conduction time (IACT), and right ventricular (RV) apical pacing (RVP) delays left ventricular (LV) contraction due to interventricular conduction time (IVCT). These delays may render the left heart AV intervals (LAV) either too short or too long, thus affecting LV systolic function. The purpose of this study was to evaluate the actual LAV intervals during conventional, right heart AAI and DDD pacing. Resulting LAV intervals were compared to programmed AV values during all DDD pacing modalities. Ten patients with DDD and six patients with AAI pacemakers were studied. IACT was measured from the atrial spike to the onset of left P wave, as recorded by an esophageal lead. Systolic time intervals were measured using either a carotid pulse tracing or a densitogram (photoplethysmography). LV function was appraised by measuring rate-corrected LV ejection time (LVETc). IVCT was measured indirectly as the lengthening of LV preejection period (PEP) caused by RV pacing, as compared to normal depolarization pathway. Intrinsic IACT and IVCT were considered zero. Right heart AV intervals (RAV) were measured from surface ECG and LAVs were calculated according to the following equations: Sinus Rhythm: LAV = RAV; Atrial Pace + Ventricular Sense: LAV = RAV - IACT; Atrial Sense + Ventricular Pace: LAV = RAV + IVCT; Sequential AV Pace: LAV = RAV - IACT + IVCT.(ABSTRACT TRUNCATED AT 250 WORDS)
Virtualization and its effect on operating system (2011)

Virtual Machines were derived under one simple core idea, which was to gain the ability to run multiple Operating Systems that allow time-sharing of a single computer between several multitasking Operating Systems. Virtual Machines (VMs) provide the occurrence of what is known as server consolidation, where different services that used to be bind to an individual machine to avoid interference can now be run in separate VMs all located on the same physical machine. Using VMs in this manner helps a company save money and improve in resource utilization, but at what cost to the performance of the Operating System? We tested the boot time of a single guest OS machine, using an optimization tool developed by Microsoft called BootVis, under various levels of VM implementation and different Host Operating Systems and see the effect of VM on the boot time of an operating system.
An efficient lossless embedded compression engine using compacted-FELICS algorithm (2008)

The memory bandwidth and capacity have become a critical design issue in display media chip for high-end display applications. In this paper, the lossless embedded compression engine using compacted-FELICS algorithm, which primarily consists of adjusted binary code and Golomb-Rice code, is proposed to handle this scenario. The encoding capability of its VLSI architecture can achieve Full-HD 1080p@60Hz. The prototype chip is implemented by TSMC 0.18-um with Artisan cell library, and its core size is 0.98mm x 0.97mm.
Studies on the role of the host immune response in recovery from Friend virus leukemia. I. Antiviral and antileukemia cell antibodies. (1976)

The humoral immune response to Friend virus leukemia was studied in congenic F1 mice differing in their incidence of recovery from leukemia. Antiviral neutralizing antibodies rose in titer in vivo concurrently with disappearance of viremia and fall in spleen virus levels. Cytotoxic antileukemia cell antibodies also appeared at this time. Passive transfer of these antibodies could inactivate low numbers of leukemia cells in vivo; however, mice of both high and low recovery genotypes produced antibodies in equal titer and recovered from viral infection in spite of striking differences in recovery from leukemic splenomegaly. Mice lacking C57BL genes did not produce antibodies or recover from viremia except in rare instances. Recovery from splenomegaly was found to be influenced by three or more C57BL genes independent of the H-2 complex.
Engineering of particles for inhalation (2009)

Current pharmaceutical engineering for the manufacture of binary and combined dry powder inhaler (DPI) dosage forms relies on destructive strategies such as micronisation to generate respirable drug particles. Such processes are inefficient and difficult to control to produce particles of defined quality and functionality for inhaled drug delivery, which can affect drug product performance throughout the shelf-life of the product. Furthermore, owing to current pharmaceutical manufacturing practises of combined inhalation products, these products are subject to greater variability in dose delivery of each active, which may be perpetuated as a function of product storage conditions and limit clinical efficacy of the drug product. Hence, there is a requirement of processes that may enable production of binary and combination DPI products that will allow actives to be delivered more efficiently and independently of dose variations. The aim, therefore, of this study was to develop the solution atomisation and crystallisation by sonication (SAX) process for engineering of single and combination drug particles with suitable physicochemical properties for delivery to the lungs. The SAX process consists of key stages, which include, solution atomisation to produce aerosol droplets, generation of highly supersaturated droplets by evaporation of carrier solvent from aerosol droplet, collection of droplets in a crystallisation vessel containing appropriate non-solvent and the application of ultrasonic waves to the crystallisation vessel. Atomisation of a 1.5% w/v solution of budesonide in dichloromethane resulted in particles with defined surface geometry, which were formulated in binary dry powder inhaler (DPI) formulations and assessed using the next generation impactor.
Structural phase stability and electron-phonon coupling in lithium (1999)

First-principles calculations of the free energy of several structural phases of Li are presented. The density-functional linear-response approach is used to calculate the volume-dependent phonon frequencies needed for computing the vibrational free energy within the quasiharmonic approximation. We show that the transformation from a close-packed structure at low temperatures to the bcc phase upon heating is driven by the large vibrational entropy associated with low-energy phonon modes in bcc Li. In addition, we find that the strength of the electron-phonon interaction in Li is strongly dependent on crystal structure. The coupling strength is significantly reduced in the low-temperature close-packed phases as compared to the bcc phase, and is consistent with the observed lack of a superconducting transition in Li.
3.5 Gb/s×4 ch optical interconnection module for ATM switching system (2002)

The developed optical interconnection module contains an AlN ceramic package with low thermal resistance, an LSI chip integrating the 3.5-Gb/s, 4-ch transmitter or receiver, and an optical submodule, which is assembled using a new passive-alignment technique. The use of the LSI chip reduces size to 6.5 cc and power dissipation to 6.1 W. The time needed to assemble the optical submodule is decreased to 1/20 by using the passive-alignment technique.
Removal of contaminating TEM-la beta-lactamase gene from commercial Taq DNA polymerase. (2006)

This study confirms that Taq DNA polymerase could be contaminated with the blaTEM-1(a) gene. It also proposes two different methods that could be used to overcome DNA contamination: (i) DNase I treatment prior to PCR amplification; and (ii) the use of a highly purified Taq DNA polymerase which was devoid of detectable contamination.

Phase Altimetry With Dual Polarization GNSS-R Over Sea Ice (2011)

This paper evaluates the potential use of reflected signals from Global Navigation Satellite Systems as a source of opportunity for the retrieval of absolute ellipsoidal heights over sea ice. Accurate estimation of the surface level would be helpful for the determination of the ice thickness, a key parameter for classification and characterization of sea ice masses. Our analysis is based on altimetric estimations from the coherent differential phase between direct and both cross- and co-polar reflected signals. For this purpose, GPS waveforms have been collected from a fixed platform in Greenland, monitoring the complete process of sea ice formation and melting during a 7-month period. The variability of coherent phase samples and polarimetric measurements are compared with in situ observations to make a realistic rough characterization of the ice cover. The retrieved sea ice surface height estimates are then evaluated against an Arctic tide model, ice surface temperature from moderate-resolution imaging spectroradiometer, and the laser altimetry product from ICESat.

Mechanoresponsive system based on sub-micron chitosan-functionalized ferromagnetic disks (2011)

We report a doxorubicin loaded chitosan biopolymer–ferromagnetic disks hybrid system capable of on-demand magnetomechanically induced release of drug molecules. Gold covered ferromagnetic disks were encapsulated into the polymer scaffold through the assembly of the thiolated chitosan on the disk's gold surface followed by entrapping of the doxorubicin drug within a cross-linked polymer matrix. We demonstrate that the release process can be effectively tuned and controlled by varying the magnetic field characteristics: orientation, amplitude, frequency and duration.
Disease-modifying antirheumatic drugs (1997)

The case for early intervention with disease-modifying antirheumatic drugs is strengthened by published reports during the past year. These drugs include methotrexate, gold sulfasalazine, and antimalarial agents. The American College of Rheumatology issued guidelines for the management of rheumatoid arthritis and for monitoring the toxicity of antirheumatic drugs. Studies on the mechanisms of action of disease-modifying antirheumatic drugs focused on their effects on cytokines and their receptors. The toxic effects of disease-modifying antirheumatic drugs remained an important issue, especially the adverse pulmonary effects of methotrexate. An important trial demonstrated a beneficial effect of triple disease-modifying antirheumatic drug therapy (methotrexate, sulfasalazine, and hydroxychloroquine) over individual agents.
Combining the Good Things from Vehicle Networks and High-Performance Networks (2007)

The aim of this Master’s thesis is to develop a solution for combining speed and performance of switched Ethernet with the real time capability and determinism of sophisticated in- vehicle networks. After thorough research in vehicle network standards, their demands and features, the Flexible Time Division Multiple Access (FTDMA) protocol of FlexRay was chosen to be applied on a switched Ethernet architecture since it can accommodate both hard real time tasks and soft real time tasks. To provide hard real time capability, what this paper focuses on, a media access method was developed by creating static TDMA schedules for each node’s sending and receiving port according to a certain traffic assumption. To validate the developed media access algorithm several examples with different traffic assumptions and architectures were generated and investigated based on their sending and receiving utilization. A second method for validating and thus proving the functionality of the algorithm was by simulation. Therefore the Matlab Simulink media library extension TRUE TIME was used to simulate a simple example with 100% sending and receiving utilization for each node.
Effects of novel retinoic acid compound, 9-cis-retinoic acid, on proliferation, differentiation, and expression of retinoic acid receptor-alpha and retinoid X receptor-alpha RNA by HL-60 cells (1993)

Abstract Retinoic acid modulates proliferation and differentiation of a wide variety of normal and leukemic cells through two distinct families of transcriptional factors: the retinoic acid receptors (RARs) and the retinoid X receptors (RXRs). A stereoisomer of retinoic acid, 9-cis- retinoic acid, is a high-affinity ligand for RXR and binds efficiently to RAR. In contrast, all-trans-retinoic acid interacts 40-fold less efficiently with RXR as compared with RAR. To clarify the biologic role of retinoic acid compounds (all-trans,- 9-cis-, and 13-cis-retinoic acid) in hematopoietic cells, we studied their effects on clonal growth, differentiation, and expression of RAR-alpha and RXR-alpha genes in HL-60 cells. At very low concentrations (10(-15) to 10(-12) mmol/L), each retinoid enhanced clonal growth of HL-60 cells. These concentrations of the retinoids had no capacity to induce differentiation of leukemic cells as measured by ability either to reduce nitroblue tetrazolium and to express CD11b antigens, suggesting that retinoids at very low concentrations may stimulate proliferation of leukemic cells rather than induce their differentiation. These findings may help explain why patients with acute promyelocytic leukemia may relapse while receiving retinoic acids. With continuous therapy, retinoids are metabolized rapidly with increased urinary excretion, lowering their plasma levels to a range that may stimulate proliferation without inducing differentiation of leukemic cells. In contrast, we found that at higher concentrations (> or = 10(-11) mmol/L) each retinoid inhibited clonal growth, reduced c-myc RNA levels, and induced differentiation of HL-60 cells. 9-cis-retinoic acid was a slightly more potent inducer of differentiation than all-trans- retinoic acid; the mechanism for this increased potency and its clinical potential requires additional studies. Steady-state levels of RAR-alpha mRNA in HL-60 cells were not affected by either 9-cis- and all-trans-retinoic acid. In contrast, 9-cis-retinoic acid, but not all- trans-retinoic acid, reduced RXR-alpha mRNA accumulation in a dose- dependent manner.
Facile Fabrication of Heterostructured Bi<sub>2</sub>O<sub>3</sub>–ZnO Photocatalyst and Its Enhanced Photocatalytic Activity (2012)

The development of coupled semiconductor photocatalysts makes a significant advancement in catalytic functional materials. A new heterostructured Bi2O3–ZnO, synthesized by a simple hydrothermal–thermal decomposition method, exhibited higher photocatalytic activity for the degradation of Acid Black 1 (AB 1) under UV light than pure ZnO, Bi2O3, and commercial Degussa P25. X-ray powder diffraction analysis reveals that the as-synthesized product has the monoclinic lattice phase of Bi2O3 and the hexagonal wurtzite phase of ZnO. HR-SEM images show that Bi2O3–ZnO has an ordered mixture of nanofiber and nanochain structures. This heterostructured Bi2O3–ZnO has increased UV absorption when compared with ZnO. The enhanced photocatalytic activity of Bi2O3–ZnO is attributed to the low recombination rates of photoinduced electron–hole pairs, caused by the vectorial transfer of electrons and holes between ZnO and Bi2O3. Higher efficiency at neutral pH 7 and reusability in the degradation of AB 1 makes Bi2O3–ZnO, a promising candidate for the photocatalytic treatment of dye effluent.
The study of gemcitabine in combination with other chemotherapeutic agents as an effective treatment for prostate cancer. (2000)

Our results demonstrated the potent activity of gemcitabine against prostate cancer in the Dunning rat model and suggest the addition of paclitaxel may not aid in this activity.
Novel compounds possessing potent cAMP and cGMP phosphodiesterase inhibitory activity. Synthesis and cardiovascular effects of a series of imidazo[1,2-a]quinoxalinones and imidazo[1,5-a]quinoxalinones and their aza analogs (1991)

A series of novel imidazoquinoxalinones and their aza analogues were prepared by the cyclization of o-amino(1H-imidazol-1-yl)aryls and heteroaryls with carbonyldiimidazole. The compounds were screened for inhibition of Type I and Type IV phosphodiesterases (PDE's) and evaluated for their vasorelaxant and positive inotropic activities in vitro. In general, compounds having potent PDE inhibitory activity also possessed good inotropic and vasodilator activity, although linear correlations between these activities could not be established.
