Dielectric Properties of (Ba, Sr)TiO3 Thin Films Deposited by RF Sputtering (1993)

Thin films of (Ba 0.65 Sr 0.35 )TiO 3 (BST) have been prepared by an rf-sputtering method at substrate temperatures of 500 to 700°C. The dielectric constant of these films ranges from 190 to 700 at room temperature. This value changes with the grain size rather than the film thickness. The dielectric constant of about 300 and leakage current density of about 1×10 -8 A/cm 2 are obtained in the 65-nm-thick film deposited at a substrate temperature of 600°C. This shows the BST film can be applied to dielectrics of dynamic random access memory (DRAM) capacitors.
Signal Processing Techniques for Real-Time Radar Applications. (1973)

The purpose of the report is to compare various combinations of signal modulations and digital processing techniques and to evaluate them in terms of performance versus computer time. Several mathematical techniques for representation of discrete convoltion of narrow band high frequency signals are presented, including a new technique called piecewise polynomial convolution. Applications of efficient FFT and Hadamard transform programs to digital radar signal processing are discussed. Problems of radar detection are analyzed including the complex representation of the radar signal, definition of ambiguity function, performance criteria, and matched filter.

Fiber crowding, fiber contacts, and fiber flocculation. (1996)

The crowding of fibers in the headbox correlates with the uniformity of the paper. Using statistical geometry, we can estimate the numbers of contacts among fibers. Some formulae are derived to help quantify the effects of fiber properties on flocculation in suspensions. An effect recently reported by Kerekes and Schell is explained quantitatively. The objective is to help predict fiber performance better by obtaining better descriptors of flocculated states. Application : the tendency of a pulp to flocculate can be estimated in terms of the mean aspect ratio of its fibers.
Vision screening for frail older people: a randomised trial (2008)

Vision screening by an optometrist for frail older people living in the community in Australia does not lead to improvements in vision or vision-related quality of life after 1 year's follow-up.
Application of a general multi-model approach for identification of highly nonlinear processes-a case study (1993)

An identification method for highly nonlinear processes is proposed based on a multi-model approach and Kolmogorov-Gabor polynomials. Owing to the large number of possible terms in this general model structure, the significant terms are selected by several statistical test procedures leading automatically to a minimal-order model realization. The performance of this method is evaluated in an in-depth case study using a simulated pH neutralization process. The effects of important variables such as range of operating conditions, signal-/noise-ratio, and data length are discussed.
B 11 and B10 magic-angle spinning nuclear magnetic resonance studies of cubic boron nitride films prepared by plasma chemical vapor deposition (2001)

B 11 and B10 magic-angle spinning nuclear magnetic resonance (MAS NMR) spectroscopy was conducted to characterize cubic boron nitride films prepared by plasma chemical vapor deposition. Similarities and differences between cubic boron nitride films and polycrystals synthesized at high pressure and high temperature were clarified by chemical shift and linewidth. The same local structure and tetrahedral symmetry of boron atoms in both forms was demonstrated, and a higher defective density appeared to exist in the film form, agreeing well with results from Raman measurements. Noncubic-phase impurities, i.e., amorphous, turbostratic, and hexagonal phases, in films were also detected in B11 MAS NMR spectra, and the possibility of removing these impurities by chemical etching was demonstrated.
Regeneration difficulties in patients with FQAD can limit the use of iPSc-based cell therapy (2022)

Etiopathogenesis of fluoroquinolone-associated disability (FQAD) syndrome is not fully understood, yet research could progress by utilizing induced pluripotent stem cells (iPSc) from people with this syndrome. Similarly, iPSc, or rather their derivatives, could be used in their therapy, not only for FQAD but also for other disorders in which generated autologous iPSc and their derivatives might be helpful. Urine was collected from ten donors with FQAD, and reprogramming of these cells was conducted with the use of Epi5TM Episomal iPSC Reprogramming Kit. IPSc were generated in one out of ten person's urine cells. While urinary cells are considered the easiest mature cells to be reprogrammed into iPSc, the urinary cells from six consecutive donors quickly became senescent. Stable urine primary cell cultures could not be obtained from the three remaining donors. Repeated attempts to reprogram epithelial cells were not successful. During parallel studies conducted for healthy donors, reprogramming success was achieved in six out of ten cases. These data may suggest serious limitations in the regeneration system of individuals with FQAD. Consequently, it indicates that therapy with autologous iPSc derivatives may face serious difficulties in their case, still, the first iPSc cell line from a person with FQAD was established.
Optimal sequential waveform design for cognitive radar (2012)

This paper addresses the problem of adaptive sequential waveform design for system parameter estimation. This problem arises in several applications such as radar, sonar, or tomography. In the proposed technique, the transmit/input signal waveform is optimally determined at each step, based on the measurements in the previous steps. The waveform is determined to minimize the Bayesian Cramér-Rao bound (BCRB) for estimation of the unknown system parameter at each step. The algorithm is tested for spatial transmit waveform design in multiple-input multiple-output radar target angle estimation at very low signal-to-noise ratio. The simulations show that the proposed adaptive waveform design achieves significantly higher rate of performance improvement as a function of the pulse index, compared to identical signal transmission.
[Staining properties and applicability of spectrally pure thionine and its isomeres (author's transl)]. (1982)

Paraffin-embedded human and animal tissues were stained with spectrally pure thionine, 1,3-diaminophenthiazoniumchlorate and 1,7-diaminophenthiazoniumperchlorate. They were examined by light microscopy to determine their applicability in histologic diagnosis. Furthermore the effect of salts and of the type of dye solvent on the staining properties of histological preparations was being investigated. Essentially the following results were obtained: 1. All 3 dyes can be applied rapidly and unproblematically on all types of tissues. Under standardized conditions, i.e. dye concentration, length of staining time and kind of staining procedure, the results are reproducable. 2. Thionine and its isomeres, being basic dyes, demonstrate a special affinity for nuclei, but also do stain cytoplasm sufficiently well to make counter-staining methods unnecessary. 3. Thionine -- in contrary to its isomeres -- reacts metachromatically with certain cellular structural elements, i.e. RNA, acid mucopolysaccharides, mucin. This property aids in morphological diagnosis and additionally enlightens certain activity states. 4. Addition of salts interferes with the staining procedure. 5. Water has special significance as solvent. Furthermore the appearance and function of metachromasia, the influence of ethanol on the metachromatic reaction, the mode of action of anorganic salts are being discussed as well as the reciprocal action of biologic substrates with the dyes having been incorporated by them.
A 3D Mask Presentation Attack Detection Method Based on Polarization Medium Wave Infrared Imaging (2020)

Facial recognition systems are often spoofed by presentation attack instruments (PAI), especially by the use of three-dimensional (3D) face masks. However, nonuniform illumination conditions and significant differences in facial appearance will lead to the performance degradation of existing presentation attack detection (PAD) methods. Based on conventional thermal infrared imaging, a PAD method based on the medium wave infrared (MWIR) polarization characteristics of the surface material is proposed in this paper for countering a flexible 3D silicone mask presentation attack. A polarization MWIR imaging system for face spoofing detection is designed and built, taking advantage of the fact that polarization-based MWIR imaging is not restricted by external light sources (including visible light and near-infrared light sources) in spite of facial appearance. A sample database of real face images and 3D face mask images is constructed, and the gradient amplitude feature extraction method, based on MWIR polarization facial images, is designed to better distinguish the skin of a real face from the material used to make a 3D mask. Experimental results show that, compared with conventional thermal infrared imaging, polarization-based MWIR imaging is more suitable for the PAD method of 3D silicone masks and shows a certain robustness in the change of facial temperature.
Electron spin resonance investigation of ZrO2-supported ruthenium. Evidence of strong metal–support interaction (1989)

An e.s.r investigation of Ru/ZrO2 has shown that Ru centres are present in different oxidation states, two of which are paramagnetic: RuIII and RuI. The assignment of the electronic configuration follows from the results of the interaction of Ru/ZrO2 with CO, for the identification of RuIII and RuI, and with NO for the identification of RuII. Magnetic tensor components allow recognition of an RuIII–CO adduct (g∥= 2.039, g⊥= 2.003) and an RuI–CO adduct (g= 2.05) An RuII–NO species was also identified [g⊥= 2.00, g∥= 1.91,A⊥(N)=40 G]. The results of the interaction with O2 also have been discussed in order to give a fuller description of the electronic configuration of the surface ruthenium centres and of the interaction effects between metal and support centres. It appears that at the Ru–ZrO2 interface occurs an interaction stronger than in the Ru–γ-Al2O3 case, the strength depending also on the temperature of the pyrolysis used to obtain Ru/ZrO2 from the Ru3(CO)12/ZrO2 metal precursor. Also the analogous Rh/ZrO2 system was considered with respect to interaction with NO in order to compare the variation in the metal–support interaction owing to differences in the supported metal.
A graphtheoretic approach to the relative placement problem (1988)

The problem of placing components on a carrier is usually divided into two steps: computation of relative positions of cells; and the final placement so that the cells do not overlap and sufficient area is provided for routing. Using circumscribed rectangles as netmodels, the two-dimensional relative placement problem is translated into two one-dimensional graph-theoretic optimization problems, each of which is a constrained minimization of weighted arc lengths in a placement graph. These optimization problems are solved independently by an exact graph-theoretic algorithm with exponential complexity in the worst case and quadratic in realistic cases. Gate arrays are used as examples.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Reconfigurable N-Path MEMS Filter Based on the Periodic Commutation of Single Frequency Resonators (2020)

We present for the first time a real-time reconfigurable MEMS filter microsystem that is able to exhibit bandpass (BP) or bandstop (BS) responses in the Radio Frequency (RF) spectrum. The unit cell of the reconfigurable filter consists of a Double-Pole, Double-Throw (DPDT) switch periodically modulating two Thin-Film Bulk-Acoustic Resonators (FBARs) on the same resonance frequency. Unlike traditonal FBAR ladder filters which involve higher fabrication complexity for multi-frequency FBARs on the same chip, we propose a novel system to acheive a sharp BS filteing response by periodically commutating multiple identical FBARs. Thanks to the excellent spectral selectivity of those resonators, sharp notches can be obtained in the same frequency range by reconfiguring the commutation frequency. Experimental results demonstrate a 30 dB rejection in BS mode and a 2.5 dB Insertion Loss (IL) in BP mode, within a bandwidth set by the modulation frequency (up to 3.6% of the RF signal frequency). In BP mode, the filter exhibits a more than 20 dB out-of-band rejection for a single stage.
Epitope Prediction of Antigen Protein Using Attention-based LSTM Network (2021)

B-cells inducing antigen-specific immune responses in vivo produce large amounts of antigen-specific antibodies by recognizing the subregions (epitope regions) of antigen proteins. These antibodies can inhibit the functioning of antigen proteins. Predicting epitope regions is beneficial for the design and development of vaccines aimed to induce antigen-specific antibody production. However, prediction accuracy requires improvement. The conventional epitope region prediction methods have focused only on the target sequence in the amino acid sequences of an entire antigen protein and have not thoroughly considered its sequence and features as a whole. In the present paper, we propose a deep learning method based on long short-term memory with an attention mechanism to consider the characteristics of a whole antigen protein in addition to the target sequence. The proposed method achieves better accuracy compared with the conventional method in the experimental prediction of epitope regions using the data from the immune epitope database.
Polymorphic cDNAs encode for the methionine‐rich storage protein from Manduca sexta (1993)

By cDNA cloning and sequencing we have shown that Manduca sexta larvae produce three very closely related methionine-rich storage proteins, MMR1, MMR2 and MMR3. Out of 2256 nucleotides in the coding region, the cDNAs differ by at most twenty-one bases and this leads to a single amino acid difference between MMR1 and MMR2, and between MMR2 and MMR3, whereas MMR1 and MMR3 differ by two amino acids. Using both distance and parsimony methods, similarities between the M. sexta and Bombyx mori methionine-rich and arylphorin storage proteins were examined. Homologous proteins from the two species tend to be more closely related than are the two classes of storage proteins in a single species.
Effects of Lomefloxacin and Sparfloxacin on Human Platelet Aggregation (1995)

Platelet aggregation is inhibited by high concentrations of most antibiotics. For this reason it is important to evaluate the effects of new antimicrobial agents on platelet aggregation. Lomefloxacin and sparfloxacin are new difluorinated quinolone antimicrobial agents. The aim of this work was to evaluate in vitro the effects of lomefloxacin and sparfloxacin on adenosinediphosphate (ADP) and collagen-induced human platelet aggregation. Our data showed that both antibiotics (lomefloxacin and sparfloxacin) at therapeutic doses did not inhibit in vitro human platelet aggregation. Lomefloxacin, only at the highest tested concentration (1 mg/ml), which is far higher than the clinically achievable one, significantly (P < 0.05) inhibited collagen-induced platelet aggregation. Sparfloxacin also caused inhibition of collagen and ADP-induced human platelet aggregation only at the highest tested concentration (0.01 mg/ml), which is higher than that reached in vivo. These findings suggest that therapeutic doses of lomefloxacin and sparfloxacin do not affect human platelet aggregation.
Design Principles of the Hippocampal Cognitive Map (2014)

Hippocampal place fields have been shown to reflect behaviorally relevant aspects of space. For instance, place fields tend to be skewed along commonly traveled directions, they cluster around rewarded locations, and they are constrained by the geometric structure of the environment. We hypothesize a set of design principles for the hippocampal cognitive map that explain how place fields represent space in a way that facilitates navigation and reinforcement learning. In particular, we suggest that place fields encode not just information about the current location, but also predictions about future locations under the current transition distribu-tion. Under this model, a variety of place field phenomena arise naturally from the structure of rewards, barriers, and directional biases as reflected in the tran-sition policy. Furthermore, we demonstrate that this representation of space can support efficient reinforcement learning. We also propose that grid cells compute the eigendecomposition of place fields in part because is useful for segmenting an enclosure along natural boundaries. When applied recursively, this segmentation can be used to discover a hierarchical decomposition of space. Thus, grid cells might be involved in computing subgoals for hierarchical reinforcement learning. 1
Single-photon generation using excitation energy transfer between quantum dots via an optical near field (2008)

We demonstrated a single photon generator using quantum dots coupled by an optical near field. This nanometric single photon generator has two blockade mechanisms to create an ideal single photon source.
Quantified Volumes of Temporal Lobe Structures in Patients with Epilepsy (1996)

The T1-weighted volumetric magnetic resonance images of 31 patients with intractable temporal lobe epilepsy, and 13 control subjects matched for age and sex, were subjected to semiautomated threshold analysis. The method used proved to be relatively fast and reliable. An index of temporal lobe interhemispheric asymmetry was extracted by thresholding high-signal (white matter) pixels. Patients had significantly more asymmetrical indices for white matter and hippocampal volumes that did control subjects, and the two indices were significantly correlated, providing evidence for the validity of the white matter index. Differences in both indices were consistent with decreased tissue on the side of the focus. In classification analyses a combination of these two indices correctly predicted the side of focus at a greater rate than did either used alone. Findings provide support for the hypothesis that seizure activity is associated with atrophy in both mesial and lateral temporal lobe structures.
Current status of Ga2O3 power devices (2016)

Abstract Gallium oxide (Ga 2 O 3 ) is an emerging wide-bandgap semiconductor for high-power, low-loss transistors and diodes by virtue of its excellent material properties and suitability for mass production. In this paper, we begin by discussing the material properties of Ga 2 O 3 that make it an attractive alternative to not only Si but also other wide-bandgap materials such as SiC and GaN. State-of-the-art Ga 2 O 3 -based devices that have been fabricated to date demonstrate the performance potential for power electronics applications.
GAMESS As a Free Quantum-Mechanical Platform for Drug Research (2012)

Driven by a steady improvement of computational hardware and significant progress in ab initio method development, quantum-mechanical approaches can now be applied to large biochemical systems and drug design. We review the methods implemented in GAMESS, which are suitable to calculate large biochemical systems. An emphasis is put on the fragment molecular orbital method (FMO) and quantum mechanics interfaced with molecular mechanics (QM/MM). The use of FMO in the protein-ligand binding, structure-activity relationship (SAR) studies, fragment- and structure-based drug design (FBDD/SBDD) is discussed in detail.
Fluid Flow and Heat Transfer Analyses in Curvilinear Microchannels (2011)

Due to the wide application of curvy channels in industrial systems, various analytical, experimental and numerical works have been conducted for macro scale channels in curvilinear coordinate. Cheng [8] studied a family of locally constricted channels and in each case, the shear stress at the wall was found to be sharply increased at and near the region of constriction. O'Brien and Sparrow [9] studied the heat transfer characteristics in the fully developed region of a periodic channel in the Reynolds number range of Re=1500 to Re=25000. A level of heat transfer enhancement by about a factor of 2.5 over a conventional straight channel was observed, resulting from a highly complex flow pattern including a strong forward flow and an oppositely directed recalculating flow. Nishimura et al. They obtained the relationship between friction factor and Reynolds number. Also, they found that in the laminar flow range, the friction factor is inversely proportional to Reynolds number. Furthermore, there is small peak in the friction factor curve which was accredited to the flow transition. The numerical prediction of the pressure drop was in good agreement with the measured values until about Re= 350. Wang et al. [11] numerically studied forced convection in a symmetric wavy wall macro channel. Their results showed that the amplitudes of the Nusselt number and the skin-friction coefficient increase with an increase in the Reynolds number and the amplitude-wavelength ratio. The heat transfer enhancement is not significant at smaller amplitude wavelength ratio; however, at a sufficiently larger value of amplitude wavelength ratio the corrugated channel will be seen to be an effective heat transfer device, especially at higher Reynolds numbers. Also in microscale gas flows, various analytical, experimental and numerical works have been conducted. Arkilic et al. [12] investigated helium flow through microchannels. It is found that the pressure drop over the channel length was less than the continuum flow results. The friction coefficient was only about 40% of the theoretical values. Beskok et al.
