We use numerical simulation methods to determine the magnetic specific heat of ${\mathrm{Eu}}_{0.25}$ ${\mathrm{Sr}}_{0.75}$ and ${\mathrm{Eu}}_{0.54}$ ${\mathrm{Sr}}_{0.46}$S as a function of field and temperature over the range $0.1\ensuremath{\le}T\ensuremath{\le}3$ K and $0\ensuremath{\le}B\ensuremath{\le}6$ T. For $x=0.25$ agreement with experiment is obtained at 1 K for $B>1$ T; for $x=0.54$ agreement is obtained at 1 K in zero field and for fields above 1 T. Possible explanations for the discrepancy at low fields are advanced. The calculations are carried out in the independent-boson approximation so that as a by-product we obtain data on the field dependence of the distribution of magnon modes. The effect of fields above 3-4 T is to introduce a uniform shift in the magnon energies. At low fields the effect is more complicated as it involves a change in the relative distribution of the modes as well as a shift in their energies. Since the calculations involve no adjustable parameters, they provide additional confirmation of earlier results that magnons make the dominant contribution to the specific heat of Heisenberg spin glasses at low temperatures.

Microbiology of Bartholin's Gland Abscess in Japan (2005)

This study was conducted to determine the current epidemiology concerning the causative organisms for Bartholin's gland abscess in Japan. Microbiological examination of 224 cases showed positive results in 219 cases and negative results in 5 cases. Of all of the bacterial isolates, 307 and 118 were aerobes and anaerobes, respectively. The most frequently isolated bacterium was Escherichia coli. Of the anaerobes, the most frequently isolated organism was Bacteroides species, followed by Prevotella species. The organisms related to respiratory infectious diseases, such as Streptococcus pneumoniae and Haemophilus influenzae, including resistant bacteria, were sometimes involved between 2000 and 2004.
Demonstration of single-sided Compton scatter tomography in fan beams with an HPGe array (2005)

An instrument is demonstrated whereby radiographic images of a sample's electron density are compiled from the information encoded in the energy spectra of gamma rays backscattered from one side of the sample. Nondestructive inspection of aluminum airframes is the application of interest, so it is assumed that access is restricted to only one surface of the object under inspection. Use of energy coding allows imaging in a fan beam rather than independent interrogation of individual volume elements. The Multiplexed Compton Scatter Tomograph (MCST) instrument consists of an array of planar high-purity germanium detectors, a set of fan beam collimators, and a Cd/sup 109/ radionuclide source. Instrument signals are converted to electron density images using a penalized weighted least squares image reconstruction algorithm coupled with a deterministic system model that includes effects of finite source and detector size, detector resolution and efficiency, attenuation, and Doppler broadening. The Doppler broadening, resulting from the momentum distribution of bound electrons, is significant at the energies used here. The proof-of-principle instrument is demonstrated on some aluminum samples. In an 8-mm thick sample with a 4 mm void in its center, contrast recovery of 90% is achieved. In a 10-mm thick sample with a 3 rum void at the back, about 85% of the contrast is recovered.
The Preparation of Some Compounds for Testing as Insect Repellents (1945)

Abstract : 743 organic compounds have been prepared and tested for use as insect repellents. Of these compounds, 63 exceeded the minimum repellency criteria of 180 minutes against aedes aegypti and/or 120 minutes against aedes quadrimaculatus. Three compounds which did not exceed the minimal values were found to be superior to dimethyl phthalate on paired testing. Among the compounds tested after impregnation in cloth 14 were repellent against A. aegypti for more than ten days. Several were still effective after 15 and 20 days when the tests were terminated. The most promising insect repellents are 0-7021, 0-7026, 0-7090, 0-7102, and 0-7145.
Scaling guidelines for CMOS linear analog design (2007)

This paper proposes scaling guidelines for CMOS analog design during a technology migration. The scaling rules aim to be easy to apply and are based on the simplest MOS transistor model. The principle is to transpose one circuit topology from one technology to another, while keeping the main figures of merit, and the issue is to quickly calculate the new transistor dimensions. Furthermore, when the target technology has smaller minimum length, we expect to obtain a decrease of area. The proposed guidelines are applied to linear examples: OTAs. The results are compared on four CMOS processes whose minimum length are 0.8 mum, 0.35 mum, 0.25 mum and 0.12 mum.
Dose and time effects of treatment with low doses of a LRH agonist on testicular axis and accessory sex organs in rats (1986)

LRH and its agonists have been shown to exert both stimulatory and inhibitory effects on testicular function. In the present study, the dose and length of treatment were tested to determine the appearance of the stimulatory and inhibitory effects of LRH agonist on testicular axis including the three levels. Two doses of an agonist of LRH, 40 and 100 ng/100 g body weight (buserelin, 'agonist'), were administered daily for 1 to 15 days to adult male rats. Control rats received the vehicle only. On day 1, 2, 4, 8 and 15 of treatment, the pituitary, testicular and peripheral levels (weight of accessory sex organs and androgen receptors in ventral prostate) were tested 6 h after the last injection. For the 15 days of treatment with both doses, a stimulatory effect of the 'agonist' was observed on LH and FSH release. A short exposure (1-2 days) to the low dose of the 'agonist' had a stimulatory effect on the density of LH/hCG testicular receptors (326 +/- 49 vs control 185 +/- 21 fmol/mg protein, mean +/- SEM), on the weights of seminal vesicles and ventral prostate and exposure to both doses led to high plasma testosterone levels (13.8 +/- 0.5 and 13.7 +/- 0.7 ng/ml, respectively, vs control 2.6 +/- 0.3 ng/ml), and to an increased density of nuclear androgen receptors in the ventral prostate (142 +/- 9 and 144 +/- 15 fmol/mg protein respectively vs control 97 +/- 12 fmol/mg protein).(ABSTRACT TRUNCATED AT 250 WORDS)

Noncrossing Monochromatic Subtrees and Staircases in 0-1 Matrices (2014)

The following question is asked by the senior author (Gyárfás (2011)). What is the order of the largest monochromatic noncrossing subtree (caterpillar) that exists in every 2-coloring of the edges of a simple geometric <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:msub><mml:mi>K</mml:mi><mml:mrow><mml:mi>n</mml:mi><mml:mo>,</mml:mo><mml:mi>n</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math>? We solve one particular problem asked by Gyárfás (2011): separate the Ramsey number of noncrossing trees from the Ramsey number of noncrossing double stars. We also reformulate the question as a Ramsey-type problem for 0-1 matrices and pose the following conjecture.

Inositol 1,3,4,5-tetrakisphosphate-induced release of intracellular Ca2+ in SH-SY5Y neuroblastoma cells (1990)

Inositol-polyphosphate-induced Ca2+ mobilization was investigated in saponin-permeabilized SH-SY5Y human neuroblastoma cells. Ins(1,4,5)P3 induced a dose-related release from intracellular Ca2+ stores with an EC50 (concn. giving half-maximal effect) of 0.1 microM and a maximal release of 70%. Ins(1,3,4)P3, DL-Ins(1,4,5,6)P4 and Ins(1,3,4,5,6)P5 did not evoke Ca2+ mobilization in these cells when used at concentrations up to 10 microM. However, Ins(1,3,4,5)P4 was found to release Ca2+ in a dose-related manner, but the response was dependent on the source of Ins(1,3,4,5)P4 used. When commercially available D-Ins(1,3,4,5)P4 was used, the EC50 and maximal response values were 1 microM and 50% respectively, compared with values for chemically synthesized DL-Ins(1,3,4,5)P4 of 2 microM and 25%. The enhanced maximal response of commercial D-Ins(1,3,4,5)P4 was decreased by pretreatment with rat brain crude Ins(1,4,5)P3 3-kinase and was therefore concluded to be indicative of initial Ins(1,4,5)P3 contamination of the Ins(1,3,4,5)P4 preparation. When metabolism of DL-Ins(1,3,4,5)P4 (10 microM) in these cells at 25 degrees C was investigated by h.p.l.c., substantial amounts of Ins(1,4,5)P3 (0.2 microM) and Ins(1,3,4)P3 (0.8 microM) were found to be produced within 3 min. Analysis of DL-Ins(1,3,4,5)P4 incubation with cells at 4 degrees C, however, indicated that metabolism had been arrested ([3H]Ins(1,4,5)P3 detection limits were estimated to be approx. 0.01 microM). When chemically synthesized DL-Ins(1,3,4,5)P4 and incubation conditions of low temperature were used, the Ca2(+)-releasing properties of this compound were established to be 1 microM and 19% for the EC50 and maximal response values respectively. The results obtained strongly suggest that Ins(1,3,4,5)P4 alone has the ability to release intracellular Ca2+. However, in the presence of sub-maximal concentrations of Ins(1,4,5)P3, Ca2+ release appears to be synergistic with Ins(1,3,4,5)P4, but at supramaximal concentrations not even additive effects are observed.
Spectroscopic Study of Narrow-Band Organic Metal (BEDT-ATD)<sub><b>2</b></sub>PF<sub><b>6</b></sub>(THF) without Dimerized Structure (1999)

The polarized reflection spectrum indicates that the organic metal (BEDT-ATD) 2 PF 6 (THF) has a quasi-one-dimensional band structure with a narrow bandwidth of ca. 0.24 eV. The intra-HOMO-band transition of (BEDT-ATD) 2 PF 6 (THF) shows two broad peaks at ca. 1000 cm -1 and 1700 cm -1 which feature is quite different from the Drude-like metallic absorption. The vibronic bands interfering with this absorption band begin to grow as dips at 100 K, which means that the screw-axis symmetry of the space group P 2 1 / a is broken below 100 K. This broken symmetry is supported by the splitting of the Raman band of a charge-sensitive vibrational mode. It is suggested from the comparison with the thermopower's data that this structural change has no long-range-ordered modulation above 50 K. The intensity of some infrared-active vibrational modes is enhanced by the intra-molecular charge oscillation whose optical transition appears at 4600 cm -1 .

Metallomacrocycles: Supramolecular Chemistry with Hard and Soft Metal Cations in Action (1994)

It has been shown in this review that complexes with both hard and soft metal cations can be used for bimetallic catalysis and activation, the formation of supramolecular aggregates, allosteric effects, and changing the redox properties of the transition metal cation. The molecular structures used to achieve these goals reflect the variety of approaches used. Although in some cases potential applications have been suggested, until now they have not evolved into prototypes. The authors feel that supramolecular structures with several different metal cations at well-defined places will be the major challenge for the next decade.
Fiber-optic temperature sensors based on differential spectral transmittance/reflectivity and multiplexed sensing systems (1995)

A concept for optical temperature sensing based on the differential spectral reflectivity/transmittance from a multilayer dielectric edge filter is described and demonstrated. Two wavelengths, λ(1) and λ(2), from the spectrum of a broadband light source are selected so that they are located on the sloped and flat regions of the reflection or transmission spectrum of the filter, respectively. As temperature variations shift the reflection or transmission spectrum of the filter, they change the output power of the light at λ(1), but the output power of the light at λ(2) is insensitive to the shift and therefore to the temperature variation. The temperature information can be extracted from the ratio of the light powers at λ(1) to the light at λ(2). This ratio is immune to changes in the output power of the light source, fiber losses induced by microbending, and hence modal-power distribution fluctuations. The best resolution of 0.2 °C has been obtained over a range of 30-120 °C. Based on such a basic temperature-sensing concept, a wavelength-division-multiplexed, temperature-sensing system is constructed by cascading three sensing-edge filters that have different cutoff wavelengths along a multimode fiber. The signals from the three sensors are resolved by detecting the correspondent outputs at different wavelengths.

Optimization of Electrolytes for High-Performance Aqueous Aluminum-Ion Batteries (2022)

Aqueous rechargeable batteries based on aluminum chemistry have become the focus of immense research interest owing to their earth abundance, low cost, and the higher theoretical volumetric energy density of this element compared to lithium-ion batteries. Efforts to harness this huge potential have been hindered by the narrow potential window of water and by passivating effects of the high-electrical band-gap aluminum oxide film. Herein, we report a high-performing aqueous aluminum-ion battery (AIB), which is constructed using a Zn-supported Al alloy, an aluminum bis(trifluoromethanesulfonyl)imide (Al[TFSI]<sub>3</sub>) electrolyte, and a MnO<sub>2</sub> cathode. The use of Al[TFSI]<sub>3</sub> significantly extends the voltage window of the electrolyte and enables the cell to access Al<sup>3+</sup>/Al electrochemistry, while the use of Zn-Al alloy mitigates the issue of surface passivation. The Zn-Al alloy, which is produced by in situ electrochemical deposition, obtained from Al[TFSI]<sub>3</sub> showed excellent long-term reversibility for Al electrochemistry and displays the highest performance in AIB when compared to the response obtained in Al<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub> or aluminum trifluoromethanesulfonate electrolyte. AIB cells constructed using the Zn-Al|Al[TFSI]<sub>3</sub>|MnO<sub>2</sub> combination achieved a record discharge voltage plateau of 1.75 V and a specific capacity of 450 mAh g<sup>-1</sup> without significant capacity fade after 400 cycles. These findings will promote the development of energy-dense aqueous AIBs.

Maxwell's Equations with Scalar Impedance: Direct and Inverse Problems (2002)

The article deals with electrodynamics in the presence of anisotropic materials having scalar wave impedance. Maxwell's equations written for differential forms over a 3-manifold are analysed. The system is extended to a Dirac type first order elliptic system on the Grassmannian bundle over the manifold. The second part of the article deals with the dynamical inverse boundary value problem of determining the electromagnetic material parameters from boundary measurements. By using the boundary control method, it is proved that the dynamical boundary data determines the electromagnetic travel time metric as well as the scalar wave impedance on the manifold. This invariant result leads also to a complete characterization of the non-uniqueness of the corresponding inverse problem in bounded domains of R^3. AMS-classifications: 35R30, 35L20, 58J45
Surface treatments to improve bond strength in removable partial dentures. (2004)

The metal and resin interface of removable partial dentures is weakened by the poor bond strength between the two materials. This study was designed to test the hypothesis that surface treatments--consisting of air abrasion, with aluminum oxide, tin plating and oxidation, and silanation, either alone or in combination--will improve the bond strength of acrylic resin to metal. Statistical analysis revealed that air abrasion, tin plating/oxidation, and silanation all showed significantly higher bond strength than either abrasion and tin plating, abrasion and silanation, or abrasion alone. Air abrasion demonstrated the greatest effect on improving bond strength. The mean bond strength of samples subjected to a combination of air abrasion, tin plating and oxidation, and silanation was significantly greater than any other combination treatment.
