Most of the research was carried out in international cooperation. We proved that in a wide class of algebras, the finite algebras that generate residually small varieties are determined by their c-ary compatible relations where c is a constant that depends only on a parameter of the class and on the size of the underlying set. We described the minimal clones with at most 4 majority operations, and those binary operations generating a minimal clone which are almost associative. We generalized the finite basis theorem of Willard to quasivarieties, and proved a conjecture of Pigozzi regarding the finite axiomatizability of relative congruence-modular quasivarieties in a special case. We characterized the idempotent separating homomorphic images of semidirect products of bands by groups, and their regular subsemigroups. We proved that each E-solid locally inverse semigroup is embeddable in a lambda-semidirect product of a completely simple semigroup by an inverse semigroup. We gave algebraic and combinatorial characterizations of the locally finite varieties omitting type 1 and of those omitting types 1 and 2. We proved a dichotomy theorem for the solvability problem of systems of polynomial equations over certain finite algebras.
Development of a pumping laser system for x-ray laser research (2003)

A two-beam chirped-pulse-amplification Nd:glass laser system dedicated to x-ray laser research is described. Each beam provides an output energy of 20 J with a typical pulse duration of 1.3 ps. A prepulse of variable duration is generated by use of a novel, to our knowledge, optical system. A reflection optical system, comprised of an off-axis parabolic mirror and a spherical mirror, produces a line focus with 6-mm length and 165-microm width without chromatic aberration. By use of this pumping laser system, the nickel-like silver x-ray laser at a wavelength of 13.9 nm has been demonstrated.

Transfer Sparse Coding for Robust Image Representation (2013)

Sparse coding learns a set of basis functions such that each input signal can be well approximated by a linear combination of just a few of the bases. It has attracted increasing interest due to its state-of-the-art performance in BoW based image representation. However, when labeled and unlabeled images are sampled from different distributions, they may be quantized into different visual words of the codebook and encoded with different representations, which may severely degrade classification performance. In this paper, we propose a Transfer Sparse Coding (TSC) approach to construct robust sparse representations for classifying cross-distribution images accurately. Specifically, we aim to minimize the distribution divergence between the labeled and unlabeled images, and incorporate this criterion into the objective function of sparse coding to make the new representations robust to the distribution difference. Experiments show that TSC can significantly outperform state-of-the-art methods on three types of computer vision datasets.

Acute systemic alcohol exposure inhibits the elicitation PUCR and RPS. Unlike cigarette smoking, systemic nicotine does not alter the elicitation of these reflexes.
Experimental Study of the Causes for Shape Error of a Large Workpiece Machined by Surface Grinding (2015)

In surface grinding of a large workpiece used for a sliding surface of the machine tool, high shape accuracy is required for the ground surface. Therefore, it is important to investigate the causes of the shape error observed in a large workpiece machined by surface grinding. In this study, we focused on the thermal deformation and residual stress as the causes of shape error. The in-process measurement of the workpiece temperature distribution was carried out to estimate the effect of the thermal deformation to the shape error. The estimated value of the shape error calculated from the measured temperature distribution was much less than the actual measured shape error. Therefore, the residual stress on the ground surface was measured with a portable X-ray stress measurement device. The residual stress was changed from compressed state to tensile state as the grinding pass increased. The ground shape was also deformed to concave shape as the grinding pass increased. The value of the shape error was finally reached to the constant value in several grinding conditions. From these experimental results, it is suggested that the shape error of the large workpiece is caused by the residual stress applied to the ground surface.

Application Of Light Valves For Continuous-Tone Printing (1989)

New opportunities are emerging in the graphic-arts pre-press market stimulated by the need for digitally created images. To meet this need, we have designed a cost-effective three-color digital printer using PLZT light valves. Transparent lead lanthanum zirconate titanate (PLZT) ceramic crystals when used as a linear modulator offer a number of significant benefits. The primary advantage is that the light valve is an efficient modulator of incoherent light providing a broad spectral output ranging from 400nm to well into the infrared region. In addition, light valves offer the advantages of being small, low cost, have a wide dynamic range (&gt;1000 to 1), and can be used with simple optical designs. The characteristics of the PLZT material plays an important role in the performance of the light valve. A number of variables such as ceramic composition, electrode spacing, and ceramic thickness can be altered to affect its quadratic electrooptic behavior. Additionally, the modulator design requires a closed-loop servo to eliminate the errors caused by the device&apos;s remanent polarization and nonlinear behavior.
Distribution of the thick-billed Grasswren in the Northern territory (2012)

Contrary to conventional views, Thick-billed Grasswrens Amytornis modestus in the Northern Territory were not distributed continuously. They occurred as two subspecies separated by up to 200 km and in distinct habitats. The nominate A.m. modestus is now presumed long extinct, but formerly occurred in a limited area of central Australia in valley floors of the upper Finke River drainage, whereas a small population presumed to be of the subspecies A.m. indulkanna occurs near the Northern Territory-South Australia border. About 100 km south of that population are further records of the latter subspecies, which occupies a large area of the western Lake Eyre drainage basin in South Australia. Further field searches are needed to establish both the size and degree of isolation of the small remnant Northern Territory population.
Ceramic bone graft substitute (Mg-HA) in spinal fusion: A prospective pilot study (2022)

<b>Background:</b> Iliac crest bone graft (ICBG) is considered the gold standard for spine surgical procedures to achieve a successful fusion due to its known osteoinductive and osteoconductive properties. However, complications related to harvesting procedure and donor site morbidity have been largely reported in the literature, favoring the development of a wide range of alternative products to be used as bone graft extenders or substitutes for spine fusion. Among all, ceramic-based biomaterials have been widely studied and employed in the last years as bone graft substitutes. <b>Methods:</b> We report here the results of a prospective pilot study aimed to evaluating the grade of ossification obtained by the use of an Mg-doped hydroxyapatite (HA) product to achieve postero-lateral fusion in degenerative spine diseases. <b>Results:</b> Results show a successful degree of fusion of about 62% at the 12-month follow-up and an improvement of quality of life and health status following surgery, as evaluated by clinical scores (ODI, VAS, and EQ-5L). No adverse events related to the material were reported. <b>Conclusion:</b> The present pilot study shows the effectiveness and the safety profile of an Mg-doped HA bone graft substitute used to achieve postero-lateral fusion in the treatment of degenerative spine diseases, laying down the basis for further larger clinical investigations.
Three-dimensional target motion analysis using azimuth/elevation angles (2014)

We present new closed-form and low-complexity solutions for the three-dimensional (3D) target motion analysis problem using azimuth/elevation angles. A 3D pseudolinear estimator (PLE) is developed based on an approximation of the maximum likelihood (ML) cost function. Drawing on a large-sample bias analysis, a bias-compensated PLE is constructed. The concept of instrumental variables (IV) is employed to derive an asymptotically unbiased estimator. Finally a weighted IV estimator is developed to achieve an estimation performance close to the ML estimator (MLE).

New mlt deletion mutants of polyoma virus were isolated, and their abilities to produce a lytic response in mouse cells or to transform rat cells were assessed. Their properties were analyzed in terms of the sequences deleted and their effects upon the structure and functions of the viral middle and large T-antigens.
Time-of-Flight pulsed ion beam surface analysis as a means ofin situ, real-time characterization of the growth of ferro-electric and conductive oxide heterostructures (1995)

Abstract Pulsed beam Time-of-Flight Ion Scattering and Recoil Spectroscopy (TOF-ISARS) surface analysis methods have been developed which permit real-time, in situ characterization of the growth layer of multi-component oxide thin films. Results are presented from a study of the deposition of Pb, Zr, Ti and Ru using a sequential layer-by-layer deposition method under ambient oxygen pressure conditions appropriate to the growth of PZT films, revealing layer-by-layer as well as 2D and 3D island growth processes during deposition. Thermodynamic stability conditions result in modification of the layered structure during deposition, in some cases altering the layer ordering of the growth region. Calculations using the Miedema model for surface segregation are in accord with experimental results that reveal an exchange between deposited Zr and Ti atoms and an underlying Pb layer. In addition, the room temperature studies revealed that Pb grows layer-by-layer, nucleating as 2D islands, while Zr tends to form three-dimensional islands. At room temperature, the Zr surface concentration is strongly enhanced by the presence of oxygen, but at high temperatures, surface Pb is found to be stabilized by the presence of an oxygen ambient, illustrating the importance of real-time, in situ analysis of the growth layer as opposed to more conventional surface analytical methods which require interruption of the deposition process in order to characterize the film surface.
Small Molecular Allosteric Activator of the Sarco/Endoplasmic Reticulum Ca2+-ATPase (SERCA) Attenuates Diabetes and Metabolic Disorders (2015)

Dysregulation of endoplasmic reticulum (ER) Ca(2+) homeostasis triggers ER stress leading to the development of insulin resistance in obesity and diabetes. Impaired function of the sarco/endoplasmic reticulum Ca(2+)-ATPase (SERCA) has emerged as a major contributor to ER stress. We pharmacologically activated SERCA2b in a genetic model of insulin resistance and type 2 diabetes (ob/ob mice) with a novel allosteric activator, CDN1163, which markedly lowered fasting blood glucose, improved glucose tolerance, and ameliorated hepatosteatosis but did not alter glucose levels or body weight in lean controls. Importantly, CDN1163-treated ob/ob mice maintained euglycemia comparable with that of lean mice for >6 weeks after cessation of CDN1163 administration. CDN1163-treated ob/ob mice showed a significant reduction in adipose tissue weight with no change in lean mass, assessed by magnetic resonance imaging. They also showed an increase in energy expenditure using indirect calorimetry, which was accompanied by increased expression of uncoupling protein 1 (UCP1) and UCP3 in brown adipose tissue. CDN1163 treatment significantly reduced the hepatic expression of genes involved in gluconeogenesis and lipogenesis, attenuated ER stress response and ER stress-induced apoptosis, and improved mitochondrial biogenesis, possibly through SERCA2-mediated activation of AMP-activated protein kinase pathway. The findings suggest that SERCA2b activation may hold promise as an effective therapy for type-2 diabetes and metabolic dysfunction.
Differential diagnosis of hepatic neoplasms: spin echo versus gadolinium-diethylenetriaminepentaacetate-enhanced gradient echo imaging. (1991)

Early results are reported of hepatic neoplasms studied with dynamic gadolinium-diethylenetriaminepentaacetate (Gd-DTPA)-enhanced magnetic resonance imaging (MRI). The purpose of this study was to evaluate the potential of the Gd enhancement pattern for characterizing these neoplasms and to compare the performance of spin-echo (SE) to SE plus dynamic Gd-enhanced gradient-echo (GRE) pulse sequences. Forty-two patients with hepatic neoplasms were examined at 1.5 T field strength. In each patient, short and long repetition time/echo time (TR/TE) SE images were obtained, followed by pre- and post-Gd-DTPA (0.1 mmol/kg body wt), single-slice, breath-hold (13 s/scan) GRE images, which were serially acquired less than or equal to 12 min postinjection. The patterns of contrast enhancement of the various hepatic lesions were documented and analyzed. The time to peak Gd signal enhancement-to-noise ratio (SE/N), contrast-to-noise ratio (C/N), contrast (defined as the signal intensity ratio [SIR]), as well as the peak values of these quantities, were determined. The C/N and SIR values on the short and long TR/TE SE and pre-Gd GRE images for all hepatic neoplasms were also obtained. The discriminating abilities (hemangiomas vs. malignant neoplasms) of these quantities were analyzed statistically. In addition, the impact of lesion characterization on the SE versus the SE plus the Gd-enhanced GRE scans was assessed by means of a blinded reader study. Malignant hepatic neoplasms could be differentiated from hemangiomas by visual inspection of their enhancement patterns (p = 0.0009), by the time to peak C/N on Gd-enhanced images (p = 0.0002), and by the magnitude of such peak (p = 0.02). Combined SE + Gd-enhanced GRE scans afforded minor, though statistically significant (p less than 0.01), improvement of the accuracy in differentiating benign from malignant hepatic neoplasms. Late scans (12 min post-Gd) may be particularly useful in identifying hemangiomas that, unlike other neoplasms, have a significant high signal of their enhancing portions on such images.
Abstract P2101: Time Dependence Of Esophageal Injury With And Without Proactive Cooling During High-power Short-duration Radiofrequency Ablation (2022)

Background: Recent data suggest that luminal esophageal temperature (LET) monitoring during high-power short-duration (HPSD) ablation may be inadequate to prevent esophageal thermal injury during radiofrequency (RF) ablation. This is due in part to delayed responses to thermal latency and the continued temperature rise that occurs in tissues even after the cessation of RF energy with HPSD settings. Proactive esophageal cooling has been shown to reduce severe esophageal thermal injury during medium-power medium-duration RF ablation, but less is known about the effects in HPSD ablation. Objective: We aimed to quantify the time course of esophageal damage in scenarios with and without proactive esophageal cooling, hypothesizing a reduction in the resulting tissue damage with proactive esophageal cooling. Methods: Using a computer model of RF ablation in the left atrium adjacent to the esophagus, we calculated temperature over time using ablation power of 50 W for 10 s and 90 W for 4 s. We then determined the fraction of resulting damage to esophageal tissue via the Arrhenius equation and by the percentage of tissue above lethal isotherm temperature of 50°C. Transmurality of injury was then plotted over time, and results were compared between ablation with and without proactive esophageal cooling. Results: Esophageal damage increased even after the cessation of RF energy, suggesting significant thermal latency effects under HPSD ablation. Lesion growth continued for &gt;10 s after cessation of 50 W ablation energy, and for &gt;12 s after cessation of 90 W ablation energy without cooling. With proactive cooling, lesion growth after cessation of ablation energy was essentially halted. Without esophageal cooling, maximum injury transmurality reached 79% with 50 W, and 58% with 90 W. With esophageal cooling, injury transmurality remained below 20% with 50 W, and 10% with 90 W, representing reductions of 75% and 83%, respectively. Conclusions: RF ablation using HPSD settings demonstrates significant latency of effect, with tissue damage and lesion growth continuing beyond the cessation of application of RF energy. Proactive esophageal cooling significantly dampens this effect, reducing esophageal injury by up to 83%.
The C99 Fragment Of App Regulates Cholesterol Trafficking (2019)

The link between cholesterol homeostasis and the cleavage of the amyloid precursor protein (APP), and their relationship to the pathogenesis of Alzheimer’s disease (AD) is still unknown. Cellular cholesterol levels are regulated by a crosstalk between the plasma membrane (PM), where most of the cholesterol resides, and the endoplasmic reticulum (ER), where the protein machinery that regulates cholesterol resides. This crosstalk between PM and ER is believed to be regulated by lipid-sensing peptide(s) that can modulate the internalization of extracellular cholesterol and/or its de novo synthesis in the ER. Our data here indicates that the 99-aa C-terminal fragment of APP (C99), a cholesterol-binding peptide, regulates cholesterol trafficking between the PM and the ER. In AD models, increases in C99 provoke the upregulation of cholesterol internalization and its delivery to the ER, which in turn result into the loss of lipid homeostasis and the appearance of AD signatures, such as higher production of longer forms of amyloid β. Our data suggest a novel role of C99 as mediator of cholesterol disturbances in AD, and as a potential early hallmark of the disease.

Novel Family of Sensor Histidine Kinase Genes in Arabidopsis thaliana (2001)

We identified three novel, highly homologous, sensor histidine kinases that possibly function in the plasma membrane of Arabidopsis thaliana, i.e. AHK2, 3 and 4. While AHK2 and 3 are expressed in several organs, AHK4 is mainly expressed in roots. AHK3 suppresses a sensor histidine kinase mutant of yeast.

75As-NQR Study on Iron-Based Oxypnictide Superconductor LaFeAsO0.6 (2008)

We report 75 As-NQR study on the oxygen-deficient iron-based oxypnictide superconductor LaFeAsO 0.6 ( T c =28 K). Nuclear spin-lattice relaxation rate 1/ T 1 of 75 As NQR at zero field on LaFeAsO 0.6 has revealed a T 3 dependence below T c upon cooling without the coherence peak just below T c , evidencing the unconventional superconducting state with the line-node gap. We have found an intimate relationship between the nuclear quadrupole frequency ν Q of 75 As and T c for LaFeAsO, LaFeAsO 0.75 , LaFeAsO 0.6 , and NdFeAsO 0.6 . It implies microscopically that the local configuration of Fe and As atoms is significantly related to the T c of the Fe-oxypnictide superconductors.
