Transverse-Mode Spurious Suppression Technique for Surface Acoustic Wave Resonator with Zero Temperature Coefficient of Frequency on a SiO2/Al/LiNbO3Structure (2012)

In this paper, we describe a suppression technique of transverse-mode spurious responses for a surface acoustic wave (SAW) resonator with a near zero temperature coefficient of frequency (TCF) on a SiO2/Al/LiNbO3 structure. We investigated the thinning of SiO2 on the dummy electrode region and studied how the transverse-mode responses change with remaining SiO2 thickness h on the dummy electrode region. As the results, we clarified that the remaining SiO2 thickness h on the dummy electrode region has an optimum value and could suppress the transverse-mode spurious responses completely when H and h are set at 0.35 λ and 0.20 λ, respectively. It was demonstrated that the selective SiO2 removal technique is effective to suppress transverse-mode spurious responses for SAW resonators employing the SiO2/Al/LiNbO3 structure for a wide range of SiO2 thicknesses, provided that the SiO2 thickness at the dummy electrode region is adjusted properly.
The Effects of Oxybutynin on Urinary Symptoms in Children with Williams-Beuren Syndrome (2012)

A total of 12 weeks of therapy with 0.6 mg/kg oxybutynin daily resulted in improvement of lower urinary tract symptoms, quality of life and maximum flow rate in most patients with Williams-Beuren syndrome.
EFFECTS OF THE RAD52 GENE ON RECOMBINATION IN SACCHAROMYCES CEREVISIAE (1980)

Effects of the rad52 mutation in Saccharomyces cerevisiae on meiotic, gamma-ray-induced, UV-induced and spontaneous mitotic recombination were studied. The rad52/rad52 diploids undergo premeiotic DNA synthesis; sporulation occurs but inviable spores are produced. Both intra and intergenic recombination during meiosis were examined in cells transferred from sporulation medium to vegetative medium at different time intervals. No intragenic recombination was observed at the his1-1/his1-315 and trp5-2/trp5-48 heteroalleles. Gene-centromere recombination also was not observed in rad52/rad52 diploids. No gamma-ray- or UV-induced intragenic mitotic recombination is seen in rad52/rad52 diploids. The rate of spontaneous mitotic recombination is lowered five-fold at the his1-1/his1-315 and leu1-c/leu1-12 heteroalleles. Spontaneous reversion rates of both his1-1 and his1-315 were elevated 10 to 20 fold in rad52/rad52 diploids.-The RAD52 gene function is required for spontaneous mitotic recombination, UV- and gamma-ray-induced mitotic recombination and meiotic recombination.
Selective Oxygenation of Cyclohexene by Dioxygen via an Iron(V)-Oxo Complex-Autocatalyzed Reaction (2017)

An iron complex with a tetraamido macrocyclic ligand, [(TAML)Fe<sup>III</sup>]<sup>-</sup>, was found to be an efficient and selective catalyst for allylic oxidation of cyclohexene by dioxygen (O<sub>2</sub>); cyclohex-2-enone was obtained as the major product along with cyclohexene oxide as the minor product. An iron(V)-oxo complex, [(TAML)Fe<sup>V</sup>(O)]<sup>-</sup>, which was formed by activating O<sub>2</sub> in the presence of cyclohexene, initiated the autoxidation of cyclohexene with O<sub>2</sub> to produce cyclohexenyl hydroperoxide, which reacted with [(TAML)Fe<sup>III</sup>]<sup>-</sup> to produce [(TAML)Fe<sup>V</sup>(O)]<sup>-</sup> by autocatalysis. Then, [(TAML)Fe<sup>V</sup>(O)]<sup>-</sup> reacted rapidly with [(TAML)Fe<sup>III</sup>]<sup>-</sup> to produce a μ-oxo dimer, [(TAML)Fe<sup>IV</sup>(O)Fe<sup>IV</sup>(TAML)]<sup>2-</sup>, which was ultimately converted to [(TAML)Fe<sup>V</sup>(O)]<sup>-</sup> when [(TAML)Fe<sup>III</sup>]<sup>-</sup> was not present in the reaction solution. An induction period was observed in the autocatalytic production of [(TAML)Fe<sup>V</sup>(O)]<sup>-</sup>. The induction period was shortened with increasing catalytic amounts of [(TAML)Fe<sup>V</sup>(O)]<sup>-</sup> and cyclohexenyl hydroperoxide, whereas the induction period was prolonged by adding catalytic amounts of a spin trapping reagent such as 5,5-dimethyl-1-pyrroline N-oxide (DMPO). The allylic oxidation of cycloalkenes was also found to depend on the allylic C-H bond dissociation energies, suggesting that the hydrogen atom abstraction from the allylic C-H bonds of cycloalkenes is the rate-determining radical chain initiation step. In this study, we have shown that an iron(III) complex with a tetraamido macrocyclic ligand is an efficient catalyst for the allylic oxidation of cyclohexene via an autocatalytic radical chain mechanism and that [(TAML)Fe<sup>V</sup>(O)]<sup>-</sup> acts as a reactive intermediate for the selective oxygenation of cyclohexene with O<sub>2</sub> to produce cyclohex-2-enone predominantly.
Pobudzenia dodatkowe jako wskaźnik właściwego położenia elektrody podczas ablacji drogi węzłowej o wolnym przewodzeniu (2001)

Pobudzenia dodatkowe podczas ablacji wolnej drogi wezlowej Cel pracy: Ocena pobudzen dodatkowych wyzwalanych podczas ablacji wolnej drogi wezlowej (SP, slow pathway) jako wskaźnika wlaściwego polozenia elektrody. Material i metody: 70 chorych (41 ± 14 lat; 50 kobiet) z nawrotnym czestoskurczem przedsionkowo-wezlowym poddano ablacji SP. Z 510 aplikacji prądu RF (ARF, application RF) przeanalizowano przebieg 464 wykonanych podczas rytmu zatokowego. Badano wystepowanie i rodzaj pobudzen dodatkowych: wezlowych (JPB, junctional premature beats), dolnoprzedsionkowych (APB, low-atrial premature beats), komorowych (VPB, ventricular premature beats). Badanie elektrofizjologiczne pozwolilo wyroznic ARF: trwale skuteczne (65), przejściowo skuteczne (50) i nieskuteczne (349). Wyniki: Dodatkowe pobudzenia wezlowe cześciej (p Rodzaj wzbudzanych pobudzen zalezy prawdopodobnie od miejsca aplikacji. Podczas ARF 
w dystalnej cześci SP (tj. na jej koncu wezlowym) pobudzenie wywolane przez cewnik szybciej dociera do przedsionka przez wezel i droge szybką (wstecznie) niz przez SP — powstaje JPB. Aktywacja z proksymalnej cześci SP najpierw obejmuje przedsionek w okolicy ujścia zatoki wiencowej, a nastepnie dociera do peczka Hisa przez droge szybką — powstaje APB. Aplikacje w strefie pośredniej wywolują oba rodzaje pobudzen. APB mogą prawdopodobnie byc wzbudzane nie tylko w SP, ale rowniez w jej sąsiedztwie (ARF bedzie nieskuteczna) — stąd ich mniejsza wartośc rokownicza.
 Wnioski: JPB w czasie ARF są czynnikiem potwierdzających wlaściwe polozenie elektrody. Nie ma pelnej zgodności w ocenie wartości rokowniczej APB. Bezsprzecznie pozwalają one roznicowac aplikacje nieskuteczne od przejściowo skutecznych. Podczas aplikacji w obszarze środkowoprzegrodowym cześciej wystepują JPB. (Folia Cardiol. 2001; 8: 65–72)
Effects of Intraperitoneally Administered Folic Acid on the Healing of Repaired Tibial Nerves in Rats (2014)

In this study, 6-week intraperitoneal administration of 80 µg/kg of folic acid significantly improved peripheral nerve healing. Histological analysis of the group that received folic acid revealed increased axon myelination with little granular tissue or fibrosis. We propose that folic acid supplementation may be an effective component of peripheral nerve injury treatment.
Antimicrobial Susceptibility Patterns and Macrolide Resistance Genes of β-Hemolytic Streptococci in Korea (2004)

In 540 beta-hemolytic streptococci, the rates of resistance to tetracycline, chloramphenicol, erythromycin, and clindamycin were 80.0, 22.8, 20.2, and 19.1%, respectively. Of the erythromycin-resistant isolates, 63.3% had the constitutive macrolide-lincosamide-streptogramin B (MLS(B)) resistance phenotype, 23.9% had the M phenotype, and 12.8% had the inducible MLS(B) resistance phenotype. The constitutive MLS(B) resistance phenotype with the erm(B) gene was dominant in Korea.
The Application of a New Drilling Model for Evaluating Formation and Downhole Drilling Conditions (1992)

Abstract A new drilling model has been developed for the interpretation of downhole drilling conditions using surface and downhole drilling data. This model is based on the analysis of the interaction of the drill bit (PDC or impact) and the formation under in situ pressure conditions. It combines downhole and surface drilling data with MWD formation measurements to provide detailed drilling analyses for real-time applications. An expression for Drilling Response developed from the model provides information on lithologic changes and allows interpretation of downhole drilling conditions. Drilling Response is a function of lithology, pore pressure, mud pressure and bit properties and is computed from the following drilling parameters: rate of penetration, bit revolutions, and downhole weight and torque on bit. Techniques and expressions allowing computation of formation porosity and pore pressure on a foot by foot basis have also been developed based on the Drilling Response. Another key feature of the model is the identification of inefficient drilling conditions. Inefficient drilling conditions are expressed in the form of Drilling Alerts for real-time applications, allowing the operator to take the necessary action to rectify the problem at the wellsite. Drilling Alerts also allow the operator to continuously monitor the effects of any remedial actions. Bit condition is evaluated using Drilling Response and torque analyses. This allows the operator to assess bearing and tooth wear conditions for impact bits and cutter wear for PDC bits. Field Examples from sedimentary basins illustrate the usefulness of the model and its applications at the wellsite and in post-drilling analysis.
Electro-optical characterization of a 2-cyclo-octylamino-5-nitropyridine thin organic crystal film (1998)

2-cyclo-octylamino-5-nitropyridine (COANP) single crystals were grown between transparent plates coated with indium tin oxide. The Pockels effect of the crystals was analyzed by an ac modulation method. The figure of merit of electro-optic phase retardation of the COANP crystals is estimated to be 4.2x10(-12) m/V . The crystals were protected by the plates, and the figure of merit of the phase retardation of the crystals did not decrease with time. We believe that the crystal-growth method described is applicable to other organic compounds whose crystal growth from a melt is feasible.
β-Lactams from allyl- and (allenylmethyl)-silanes (1990)

The N-chlorosulphonyl β-lactams formed as intermediates in the reaction between chlorosulphonyl isocyanate and allyl- and (allenylmethyl)-silanes can be intercepted by aqueous sodium sulphite; this has allowed the preparation of a range of usefully functionalised monocyclic N-protio β-lactams.

Silicide application on gated single-crystal, polycrystalline and amorphous silicon FEAs. II. Co silicide (2001)

For pt. I see ibid., vol.48, no.1, p.149-54 (Jan. 2001). For enhancement and stabilization of electron emission, Co silicides were formed from Co, Co/Ti and Ti/Co layers on silicon FEAs. Since Ti prevents oxygen adsorption on the Co film during silicidation, uniform and smooth Co silicide layers can be obtained by depositing Co first and then Ti on silicon tips, followed by rapid annealing. Among Co silicide FEAs, Co silicide formed from Ti/Co bi-layers shows the lowest leakage current, the highest failure voltage over 152 V and the largest anode current over 1 mA at the gate voltage of 150 V. Compared with silicon field emitters, the silicide FEAs formed from Ti/Co layers exhibited a significant improvement in maximum emission current, emission current fluctuation and stability, and failure voltage.
Supporting Dynamic Languages on the Java Virtual Machine (1996)

In this note, I propose two extensions to the Java virtual machine (or VM) to allow dynamic languages such as Dylan, Scheme and Smalltalk to be efficiently implemented on the VM. These extensions do not affect the performance of pure Java programs on the machine. The first extension allows for efficient encoding of dynamic data; the second allows for efficient encoding of language-specific computational elements.

Constrained least square design of FIR filters without specified transition bands (1996)

This paper puts forth the notion that explicitly specified transition bands have been introduced in the filter design literature in part as an indirect approach for dealing with discontinuities in the desired frequency response. We suggest that the use of explicitly specified transition bands is sometimes inappropriate because to satisfy a meaningful optimality criterion, their use implicitly assumes a possibly unrealistic assumption on the class of input signals. This paper also presents an algorithm for the design of peak constrained lowpass FIR filters according to an integral square error criterion that does not require the use of specified transition bands. This rapidly converging, robust, simple multiple exchange algorithm uses Lagrange multipliers and the Kuhn-Tucker conditions on each iteration. The algorithm will design linear- and minimum-phase FIR filters and gives the best L/sub 2/ filter and a continuum of Chebyshev filters as special cases. It is distinct from many other filter design methods because it does not exclude from the integral square error a region around the cut-off frequency, and yet, it overcomes the Gibbs' phenomenon without resorting to windowing or 'smoothing out' the discontinuity of the ideal lowpass filter.
Performance Evaluation of Bandwidth Allocation in 802.16j Mobile Multi-Hop Relay Networks (2007)

Being an evolution of IEEE 802.16e, IEEE 802.16j mobile multi-hop relay (MMR) is proposed to gain coverage extension and throughput enhancement. This research conducts theoretical analysis and performance evaluation on the on-demand bandwidth allocation in IEEE 802.16j MMR networks. Theoretical analysis shows that such systems using conventional bandwidth allocation will seriously suffer from low bandwidth utilization. We then develop a new, spectrum efficiency based adaptive resource allocation algorithm. Simulation results verified that, compared with conventional on-demand bandwidth allocation method, the proposed method is more bandwidth efficient and exhibits better fairness in such networks. In terms of throughput, packet loss rate and delay, the performance of SEBARA algorithm is further evaluated in an OPNET-based 802.16j MMR simulation platform. Both theoretical analysis and simulation indicate the novel method provides an attractive solution for bandwidth allocation in 802.16j MMR networks.
Thrombus Aspiration Used Alone to Treat ST Elevation Myocardial Infarction Patients with Chronic Atrial Fibrillation (2014)

The safety and effectiveness of thrombus aspiration alone without additional ballooning or stent implantation in ST-segment elevation myocardial infarction (STEMI) patients is limited. Recently, we experienced a case of a STEMI patient with chronic atrial fibrillation who was successfully treated with thrombus aspiration alone.
Future memory technology including emerging new memories (2004)

There have been concerns about how far we can extend the so far so successful conventional semiconductor memories Such as DRAM, SRAM and Flash memory and what will be the future directions of memory development. In this article, we will review the key technical limits of conventional memory scaling and the directions to overcome the problem. In addition, we will review the technical challenges and opportunities of emerging. new memories such as ferroelectric RAM (FRAM), magnetic RAM (MRAM) and phase change RAM (PRAM) which has been recently focused as candidates for ideal memory which can solve the problems of conventional memories.
Cyclodextrin-Isolated Alkynylpyrenes as UV-Stable and Blue-Light-Emitting Molecules Even in Condensed States (2016)

Encapsulation of highly emissive alkynylpyrenes with permethylated α-cyclodextrin (PM-α-CD) followed by capping reaction yielded alkynylpyrene-based [3]rotaxanes. The [3]rotaxane emitted only blue light of monomeric pyrene under various circumstances such as lipophilic, hydrophilic, and even condensed states and exhibited extremely high stability for UV irradiation. These properties would result because PM-α-CD, like bulletproof glass, protected the alkynylpyrene core from the attack of another excited alkynylpyrene and singlet oxygen generated by the energy transfer from the excited alkynylpyrene.
Mechanical and Barrier Properties of Cross-Linked Soy and Whey Protein Based Films (2001)

Sterilized biofilms based on soy protein isolate (SPI, S system) and a 1:1 mixture of SPI and whey protein isolate (WPI, SW system) were achieved through the formation of cross-links by means of gamma-irradiation combined with thermal treatments. The effect of the incorporation of carboxymethylcellulose (CMC) and poly(vinyl alcohol) was also examined. gamma-Irradiation combined with thermal treatment improved significantly the mechanical properties, namely, puncture strength and puncture deformation, for all types of films. Irradiated formulations that contain CMC behave more similarly as elastomers. CMC showed also significant improvements of the barrier properties, namely, water vapor permeability, for irradiated films of the S system and for non-irradiated films of the SW system.
Fluorescent Orthopalladated Complexes of 4-Aryliden-5(4H)-oxazolones from the Kaede Protein: Synthesis and Characterization (2021)

The goal of the work reported here was to amplify the fluorescent properties of 4-aryliden-5(4<i>H</i>)-oxazolones by suppression of the hula-twist non-radiative deactivation pathway. This aim was achieved by simultaneous bonding of a Pd center to the N atom of the heterocycle and the <i>ortho</i> carbon of the arylidene ring. Two different 4-((<i>Z</i>)-arylidene)-2-((<i>E</i>)-styryl)-5(4<i>H</i>)-oxazolones, the structures of which are closely related to the chromophore of the Kaede protein and substituted at the 2- and 4-positions of the arylidene ring (<b>1a</b> OMe; <b>1b</b> F), were used as starting materials. Oxazolones <b>1a</b> and <b>1b</b> were reacted with Pd(OAc)<sub>2</sub> to give the corresponding dinuclear orthometalated palladium derivates <b>2a</b> and <b>2b</b> by regioselective C-H activation of the <i>ortho</i>-position of the arylidene ring. Reaction of <b>2a</b> (<b>2b</b>) with LiCl promoted the metathesis of the bridging carboxylate by chloride ligands to afford dinuclear <b>3a</b> (<b>3b</b>). Mononuclear complexes containing the orthopalladated oxazolone and a variety of ancillary ligands (acetylacetonate (<b>4a</b>, <b>4b</b>), hydroxyquinolinate (<b>5a</b>), aminoquinoline (<b>6a</b>), bipyridine (<b>7a</b>), phenanthroline (<b>8a</b>)) were prepared from <b>3a</b> or <b>3b</b> through metathesis of anionic ligands or substitution of neutral weakly bonded ligands. All species were fully characterized and the X-ray determination of the molecular structure of <b>7a</b> was carried out. This structure has strongly distorted ligands due to intramolecular interactions. Fluorescence measurements showed an increase in the quantum yield (QY) by up to one order of magnitude on comparing the free oxazolone (QY < 1%) with the palladated oxazolone (QY = 12% for <b>6a</b>). This fact shows that the coordination of the oxazolone to the palladium efficiently suppresses the hula-twist deactivation pathway.
Aortic root compression during transcatheter pulmonary valve replacement (2016)

The majority of cases of ARC occur in patients with native/TAP RVOTs. ARC during BS/CCT may identify those at risk for ARC following TPVR. While ARC is a real phenomenon, it is unclear if it can be accurately predicted, what its clinical significance will be and how it is best avoided. Further studies are necessary to answer these questions. © 2016 Wiley Periodicals, Inc.
Application of 23 Novel Serological Markers for Identifying Recent Exposure to Plasmodium vivax Parasites in an Endemic Population of Western Thailand (2021)

Thailand is aiming for malaria elimination by the year 2030. However, the high proportion of asymptomatic infections and the presence of the hidden hypnozoite stage of <i>Plasmodium vivax</i> are impeding these efforts. We hypothesized that a validated surveillance tool utilizing serological markers of recent exposure to <i>P. vivax</i> infection could help to identify areas of ongoing transmission. The objective of this exploratory study was to assess the ability of <i>P. vivax</i> serological exposure markers to detect residual transmission "hot-spots" in Western Thailand. Total IgG levels were measured against a panel of 23 candidate <i>P. vivax</i> serological exposure markers using a multiplexed bead-based assay. A total of 4,255 plasma samples from a cross-sectional survey conducted in 2012 of endemic areas in the Kanchanaburi and Ratchaburi provinces were assayed. We compared IgG levels with multiple epidemiological factors that are associated with an increased risk of <i>P. vivax</i> infection in Thailand, including age, gender, and spatial location, as well as <i>Plasmodium</i> infection status itself. IgG levels to all proteins were significantly higher in the presence of a <i>P. vivax</i> infection (<i>n</i> = 144) (<i>T</i>-test, <i>p</i> < 0.0001). Overall seropositivity rates varied from 2.5% (PVX_097625, merozoite surface protein 8) to 16.8% (PVX_082670, merozoite surface protein 7), with 43% of individuals seropositive to at least 1 protein. Higher IgG levels were associated with older age (>18 years, <i>p</i> < 0.05) and males (17/23 proteins, <i>p</i> < 0.05), supporting the paradigm that men have a higher risk of infection than females in this setting. We used a Random Forests algorithm to predict which individuals had exposure to <i>P. vivax</i> parasites in the last 9-months, based on their IgG antibody levels to a panel of eight previously validated <i>P. vivax</i> proteins. Spatial clustering was observed at the village and regional level, with a moderate correlation between PCR prevalence and sero-prevalence as predicted by the algorithm. Our data provides proof-of-concept for application of such surrogate markers as evidence of recent exposure in low transmission areas. These data can be used to better identify geographical areas with asymptomatic infection burdens that can be targeted in elimination campaigns.
The association between BMI and 90-day mortality in patients with and without diabetes seeking care at the emergency department (2021)

We found divergent long-term mortality risks in patients with and without diabetes, with lower risk in obese patients (BMI ≥ 30 kg/m<sup>2</sup>) with diabetes, but no increased risk for patients without diabetes and overweight (BMI: 25-29.9 kg/m<sup>2</sup>) and obesity.
