Modeling and design of bending waveguide based semiconductor polarization rotators (1997)

A theoretical model for bending waveguide based semiconductor polarization rotators has been established, which is based on the full-vectorial wave equations for bending waveguides and coupled-mode theory. Calculation results obtained using this model and measurement data are found to be in good agreement.
Electrical Transport and Grain Growth in Solution-Cast, Chloride-Terminated Cadmium Selenide Nanocrystal Thin Films (2014)

We report the evolution of electrical transport and grain size during the sintering of thin films spin-cast from soluble phosphine and amine-bound, chloride-terminated cadmium selenide nanocrystals. Sintering of the nanocrystals occurs in three distinct stages as the annealing temperature is increased: (1) reversible desorption of the organic ligands (≤150 °C), (2) irreversible particle fusion (200-300 °C), and (3) ripening of the grains to >5 nm domains (>200 °C). Grain growth occurs at 200 °C in films with 8 atom % Cl(-), while films with 3 atom % Cl(-) resist growth until 300 °C. Fused nanocrystalline thin films (grain size = 4.5-5.5 nm) on thermally grown silicon dioxide gate dielectrics produce field-effect transistors with electron mobilities as high as 25 cm(2)/(Vs) and on/off ratios of 10(5) with less than 0.5 V hysteresis in threshold voltage without the addition of indium.

The Overview of Porous, Bioactive Scaffolds as Instructive Biomaterials for Tissue Regeneration and Their Clinical Translation (2020)

Porous scaffolds have been employed for decades in the biomedical field where researchers have been seeking to produce an environment which could approach one of the extracellular matrixes supporting cells in natural tissues. Such three-dimensional systems offer many degrees of freedom to modulate cell activity, ranging from the chemistry of the structure and the architectural properties such as the porosity, the pore, and interconnection size. All these features can be exploited synergistically to tailor the cell-material interactions, and further, the tissue growth within the voids of the scaffold. Herein, an overview of the materials employed to generate porous scaffolds as well as the various techniques that are used to process them is supplied. Furthermore, scaffold parameters which modulate cell behavior are identified under distinct aspects: the architecture of inert scaffolds (i.e., pore and interconnection size, porosity, mechanical properties, etc.) alone on cell functions followed by comparison with bioactive scaffolds to grasp the most relevant features driving tissue regeneration. Finally, <i>in vivo</i> outcomes are highlighted comparing the accordance between <i>in vitro</i> and <i>in vivo</i> results in order to tackle the future translational challenges in tissue repair and regeneration.
How Far Should Global Products Go? (1989)

Some authorities in international business have suggested that international markets are becoming increasingly homogeneous, causing more firms to offer global products. Vachani and Wells based on a study of the product decisions of Indian subsidiaries of five multinationals argue that there remain important consumer segments that have special needs which are not met by global products. According to Vachani and Wells, decisions of multinationals and local firms to cater to the special needs of various consumer segments in developing countries depend on four variables: the structure and competitive conditions of their industry segments, the ability to use their traditional competitive advantage in different segments, the ease with which their usual product lines can be extended into new segments, and the availability of more special products elsewhere within the multinational enterprise.
Combining DT and q-space MRI: a new model of white matter in the brain (2003)

The signal decay in diffusion experiments is affected by many factors, including tissue microstructure and compartmentalization. When performing diffusion experiments at high b (or q) values, non-monoexponential signal decay is observed, especially in white matter rich areas. Here we propose a mathematical model that accounts for different modes of anisotropic diffusion (restricted and hindered) and the relative orientations of the nerve fiber axis and the diffusion gradient vectors. The model was used to fit high b value experimental diffusion data from human brain, and distinguishes between diffusion in restricted and hindered compartments.

Alcaloïdes Indoliques. XIX. Un Nouvel Exemple D'empêchement a la Libre Rotation Dans des Dérivés Dihydroindoliques N‐Formylés (1969)

Abstract The proton magnetic resonance spectra of some N‐formyl dihydroindole derivatives have been investigated. The data are best rationalized on the basis of a hindered rotation about the N–CHO bond. The attribution of the signals to each conformation is obtained from the chemical shifts in the low field region and from the pattern of the aromatic protons.
The eIF4A inhibitor silvestrol sensitizes T-47D ductal breast carcinoma cells to external-beam radiotherapy (2020)

Low concentrations of silvestrol sensitize T-47D breast cancer cells to radiation with minimal effects on unirradiated cells. This highlights the possible usefulness of eIF4A inhibition in potentiating radiation-induced damage at the tumor site without causing systemic toxicity.
Room-temperature lasing action in In0.51Ga0.49P/In0.2Ga0.8As microcylinder laser diodes (1993)

We report room-temperature operation of electrically pumped whispering-gallery mode In0.51Ga0.49P/In0.2Ga0.8As microcylinder laser diodes with emission at wavelength λ=1.0 μm and threshold current Ith=5 mA. Because the lasing modes do not overlap the diode’s central region, carrier density is not efficiently pinned by above-threshold stimulated emission.
EXOGENOUSLY ADDED DIACYLGLYCEROL (DAG) AND ELEVATED INTRACELLULAR Ca2+ LEVELS CANNOT SUBSTITUTE FOR PROSTAGLANDIN END0PER0XIDES/ THROMBOXANE ki IN MEDIATING WEAK AGONIST-INDUCED PLATELET SECRETION (1987)

We have compared the abilities of exogenously added U46619, the PG endoperoxide analogue and, sn-l-oleoyl 2-acetylglycerol (OAG) and sn-1,2-dioctanoylglycerol (diCg), the membrane-permeant DAG analogues, at restoring weak agonist-induced secretion in indomethacin (10μM)-treated platelets (I-PL) in the absence of endogenous PG/Tx synthesis. [14C]-5HT secretion from pre-loaded, washed human platelets was correlated with the levels of [Ca2+]i, using platelets loaded with quin 2. Concentrations of OAG (62-125μM) and diCg (15-30μM), which have previously been shown to be fully effective at activating protein kinase C, failed to significantly enhance [14C]-5HT secretion in combination with ADP (10μM), adrenaline (10μM) or PAF (0.2μM) although they potentiated platelet aggregation, when added 10-30 sec after these agonists to I-PL. eg ADP-0%, 30jiM diCg-9.8%, ADP+diCg-11.9%, 5HT release (p&gt;O.05). In contrast, a low concentration of U46619 (0.2μM), that induced no aggregation, [14C]-5HT secretion or rise in [Ca2+]i levels on its own, was able to synergize strongly at potentiating secretion in combination with all three weak agonists examined, as well as in combination with OAG and diCg (U46619-0%, ADP+U46619-20.4%, U46619+30μM diC8-48% 5HT release) . The greater effectiveness of U46619 at potentiating secretion in combination with the weak agonists was not related to different degrees of [Ca2+]i mobilisation, as ADP and PAF-induced rise in [Ca2+]i occurred to a similar degree in the presence of U46619 and diCg. At a higher concentration of U46619 (0.6μM), which was maximally effective at inducing secretion and elevating [Ca2+]i levels on its own, addition of the weak agonists or OAG or diCg, along with U46619, resulted in a further enhancement of secretion which was independent of changes in [Ca2+]i levels. The results demonstrate that U46619 but not OAG or diCg, is able to fully restore weak agonist-induced secretion in indomethacin-treated platelets, suggesting that the actions of endogenously formed PG endoperoxides/TxA2 cannot be substituted by DAG and raised [Ca2+]i levels and, may be mediated via a mechanism additional to that involving these mediators.
Activity of Mesoporous Alumina Particles for Biomass Steam Reforming in a Fluidized-Bed Reactor and Its Application to a Dual-Gas-Flow Two-Stage Reactor System (2008)

Pulverized sugar cane bagasse (SCB) and cedar sawdust (CSD) were rapidly pyrolyzed and reformed in situ with steam in a laboratory-scale fluidized-bed reactor at temperature of 973−1123 K and steam-to-biomass mass ratio (S/B) of 0−3.5. A substantial portion of the nascent tar was converted into coke over fluidized mesoporous γ-alumina (MPGA) used as the bed material. The coke was sufficiently active to completely eliminate tar except for BTX (benzene, toluene, xylene) and naphthalene derivatives. Experimental results were used for simulating a dual-gas-flow two-stage gasification in which MPGA circulates through the reformer for producing syngas and the combustor for producing heat by burning the coke and char. The simulation predicted maximum cold gas efficiencies over 0.8 on an LHV basis for both SCB and CSD at temperature of 1073−1123 K and S/B of 0.7−0.8.
[Mini-Mult 82: review and standardization of short version of the MMPI questionnaire]. (1993)

The correction norms for the Mini-Mult 82 (71 items from Kincannon's MMPI short form, plus 11 representative items from 5(Mf) Scale from the same test--developed by the authors--) are presented. A 1,343 normal, over 15-year-old Costarrican subjects sample was tested. Correction norms were obtained successfully. More reliable scores were obtained by using the Mini-Mult 82 as an independent test (i.e. without MMPI's score predictions). Statistical differences in F, 1(Hs), 2(D), 3(Hy), 4(Pd), 5(Mf) and 8(Sc) scales were found when gender was controlled. "T" scores were computed for raw scores on each scale. Additional research is suggested to improve the test's reliability and validity characteristics.
Regulation and functional effects of ZNT8 in human pancreatic islets (2012)

Zinc ions are essential for the formation of insulin crystals in pancreatic β cells, thereby contributing to packaging efficiency of stored insulin. Zinc fluxes are regulated through the SLC30A (zinc transporter, ZNT) family. Here, we investigated the effect of metabolic stress associated with the prediabetic state (zinc depletion, glucotoxicity, and lipotoxicity) on ZNT expression and human pancreatic islet function. Both zinc depletion and lipotoxicity (but not glucotoxicity) downregulated ZNT8 (SLC30A8) expression and altered the glucose-stimulated insulin secretion index (GSIS). ZNT8 overexpression in human islets protected them from the decrease in GSIS induced by tetrakis-(2-pyridylmethyl) ethylenediamine and palmitate but not from cell death. In addition, zinc supplementation decreased palmitate-induced human islet cell death without restoring GSIS. Altogether, we showed that ZNT8 expression responds to variation in zinc and lipid levels in human β cells, with repercussions on insulin secretion. Prospects for increasing ZNT8 expression and/or activity may prove beneficial in type 2 diabetes in humans.
A Low-Profile, Triple-Band, and Wideband Antenna Using Dual-Band AMC (2023)

When a wideband antenna is backed by an artificial magnetic conductor (AMC) reflector, the bandwidth is reduced. With the optimization of the shape of the AMC it is possible to exhibit multiband behavior, but the problem becomes complex if the bands are also intended to be wide. In this study, a methodology that exploits both the expected in-band and out-of-band behaviors of a dual-band AMC was used to design a low-profile, triple-band, and wideband directive antenna. The methodology was validated with a prototype suitable for the European standards of 4G/5G and Wi-Fi 2.4/5/6E, operating within the following bands: 2.4-2.7 GHz, 3.4-3.8 GHz, and 5.17-6.45 GHz. The measured results showed respective peak values of 8.0, 9.1, and 10.5 dBi for the broadside realized gain, front-to-back ratios larger than 19 dB, cross-polarized levels lower than -18 dB, and stable half-power beamwidths within each band. Furthermore, 3 dB gain bandwidths of 34.4%, 19.7%, and 31.0% were also measured.
[The relationship between a nucleotide substitution of S100A8 gene and aggressive periodontitis]. (2004)

This is the first report that a nucleotide substitution of S100A8 gene was demonstrated in Chinese. The frequencies of allele 2 and heterozygous genotype were lower in patients, but there is no statistically significant difference between the aggressive periodontitis patients and healthy controls in this preliminary study.
Refractive index and temperature sensor based on double-pass in-line Mach-Zehnder interferometer (2011)

Different from the conventional optical fiber in-line Mach-Zehnder interferometer (MZI), we proposed and demonstrated a novel double-pass in-line fiber taper MZI as a refractive index and temperature sensor in this study. The double-pass MZI is composed of a reflecting mirror, a circulator and an in-line fiber MZI. The attenuation peaks of the double-pass MZI spectra have higher contrasts than the peaks of single-pass spectra. Using our recently proposed spectrum differential integration (SDI) analyzing method, the double-pass MZI sensors' sensitivities can be made nearly twice as large as those of the single-pass ones.
Antiinflammatory fluoroalkanesulfonanilides. 3. Other fluoroalkanesulfonamido diaryl systems (1975)

A series of isosteres of 3-benzoyltrifluoromethanesulfonanilide involving alternatives to the carbonyl linking group was synthesized and screened for antiinflammatory activity in the carrageenan rat paw edema test. The systems examined were of the type m-CF3SO2NH-C6H4-X-C6H5, where X was -CROH-, -CHR-, -CH(OH)CH2-, -COCH2-, -CH2CO-, greater than C equal to CR2, -CR equal to CH, -C identical to C-, -CH2CH2-, CONH-, -NR-, -O-, -S(O)n- (n equal to 0,1,2), and carbon-carbon single bond. Many ortho and para derivatives were also tested. Several of these new trifluoromethanesulfonanilides proved equipotent with phenylbutazone. The effects on the anticarrageenan activity of both the nature and ring position of X are discussed.

An improved synthesis of 1′‐[18F]fluoroethyl‐β‐d‐lactose ([18F]‐FEL) for positron emission tomography imaging of pancreatic cancer (2013)

An improved synthesis of [(18)F]FEL has been achieved in high yields, with high purity and specific activity. Precursor 2b with this method should be applicable for high yield automated production in a commercial synthesis module for clinical application.
Toward Mass Video Data Analysis: Interactive and Immersive 4D Scene Reconstruction (2020)

The technical progress in the last decades makes photo and video recording devices omnipresent. This change has a significant impact, among others, on police work. It is no longer unusual that a myriad of digital data accumulates after a criminal act, which must be reviewed by criminal investigators to collect evidence or solve the crime. This paper presents the VICTORIA Interactive 4D Scene Reconstruction and Analysis Framework ("ISRA-4D" 1.0), an approach for the visual consolidation of heterogeneous video and image data in a 3D reconstruction of the corresponding environment. First, by reconstructing the environment in which the materials were created, a shared spatial context of all available materials is established. Second, all footage is spatially and temporally registered within this 3D reconstruction. Third, a visualization of the hereby created 4D reconstruction (3D scene + time) is provided, which can be analyzed interactively. Additional information on video and image content is also extracted and displayed and can be analyzed with supporting visualizations. The presented approach facilitates the process of filtering, annotating, analyzing, and getting an overview of large amounts of multimedia material. The framework is evaluated using four case studies which demonstrate its broad applicability. Furthermore, the framework allows the user to immerse themselves in the analysis by entering the scenario in virtual reality. This feature is qualitatively evaluated by means of interviews of criminal investigators and outlines potential benefits such as improved spatial understanding and the initiation of new fields of application.

Cross-tier, label-based security enforcement for web applications (2009)

This paper presents SELinks, a programming language focused on building secure multi-tier web applications. SELinks provides a uniform programming model, in the style of LINQ and Ruby on Rails, with language syntax for accessing objects residing either in the database or at the server. Object-level security policies are expressed as fully-customizable, first-class labels which may themselves be subject to security policies. Access to labeled data is mediated via trusted, user-provided policy enforcement functions.
Cover Picture: Bis(trimethylsilyl)acetylene Complexes of Titanocenes and Zirconocenes: Their Recent Chemistry and Reactions with Lewis Acids (Eur. J. Inorg. Chem. 24/2004) (2004)

Abstract The cover picture shows the stable and well‐defined metallocene bis(trimethylsilyl)acetylene complexes Cp 2 M(L)(η 2 ‐Me 3 SiC 2 SiMe 3 ) (M = Ti, without L; M = Zr, L = THF, pyridine), of the pentamethylcyclopentadienyl complexes Cp* 2 M(η 2 ‐Me 3 SiC 2 SiMe 3 ) (M = Ti, Zr) and the ethylenebis(tetrahydroindenyl) complexes rac ‐(ebthi)M(η 2 ‐Me 3 SiC 2 SiMe 3 ) (M = Ti, Zr). These form an essential basis for recent applications in chemistry. By using different Cp ligands (Cp, Cp*, ebthi), additional ligands (THF, pyridine), and metals (Ti, Zr), a fine‐tuning of several stoichiometric and catalytic reactions was feasible. The latter complexes offer a number of compelling advantages over the widely used other similar metallocene reagents. As a metaphor, this piece of basic research stands “ solid as a rock in heavy seas ” (in the photo the Baltic Sea nearby Rostock‐Warnemünde), alluding to the fact that fundamental preparative organometallic chemistry provides a solid foundation for attractive applications. Details of this chemistry are described in the Microreview by U. Rosenthal et al. on p. 4739ff.
A Novel Imprinted Gene, Encoding a RING Zinc-Finger Protein, and Overlapping Antisense Transcript in the Prader-Willi Syndrome Critical Region (1999)

We describe a complex imprinted locus in chromosome 15q11-q13 that encodes two genes, ZNF127 and ZNF127AS. The ZNF127 gene encodes a protein with a RING (C3HC4) zinc-finger and multiple C3H zinc-finger motifs, the former being closely related to a protein from variola major virus, the smallpox etiological agent. These motifs allow prediction of ZNF127 function as a ribonucleoprotein. The intronless ZNF127 gene is expressed ubiquitously, but the entire coding sequence and 5' CpG island overlaps a second gene, ZNF127AS, that is transcribed from the antisense strand with a different transcript size and pattern of expression. Allele-specific analysis shows that ZNF127 is expressed only from the paternal allele. Consistent with this expression pattern, in the brain the ZNF127 5' CpG island is completely unmethylated on the paternal allele but methylated on the maternal allele. Analyses of adult testis, sperm and fetal oocytes demonstrates a gametic methylation imprint with unmethylated paternal germ cells. Recent findings indicate that ZNF127 is part of the coordinately regulated imprinted domain affected in Prader-Willi syndrome patients with imprinting mutations. Therefore, ZNF127 and ZNF127AS are novel imprinted genes that may be associated with some of the clinical features of the polygenic Prader-Willi syndrome.

Accurate lithography simulation model based on convolutional neural networks (2017)

Lithography simulation is an essential technique for today's semiconductor manufacturing process. In order to calculate an entire chip in realistic time, compact resist model is commonly used. The model is established for faster calculation. To have accurate compact resist model, it is necessary to fix a complicated non-linear model function. However, it is difficult to decide an appropriate function manually because there are many options. This paper proposes a new compact resist model using CNN (Convolutional Neural Networks) which is one of deep learning techniques. CNN model makes it possible to determine an appropriate model function and achieve accurate simulation. Experimental results show CNN model can reduce CD prediction errors by 70% compared with the conventional model.
Pattern Recognition Studies of Halogenated Organic Compounds Using Conducting Polymer Sensor Arrays (1998)

Direct measurement of volatile and semivolatile halogenated organic compounds of environmental interest was carried out using arrays of conducting polymer sensors. Mathematical expressions of the sensor arrays using microscopic polymer network model is described. A classical, nonparametric, and unsupervised technique of cluster analysis was used to discriminate between polychlorinated organic phenol vapor response vectors in 2-dimensional space and to identify clusters or groups to which unknown vectors are likely to belong. The characteristic pattern for each sample was used to generate the database employed in the determination of the Euclidean distances between two given patterns and the normalized sensor response, as well as to develop a 2-dimensional mapping from a multidimensional space for quantifying the distinction of the samples. Results obtained demonstrated that conducting polymer sensor arrays can be utilized in the identification and quantitation of chlorinated organic phenols based on the differences in their Euclidean distances. The systematic differences, qualitatively defined by the Euclidean difference measurements, were most clearly visible when the nature and the function of the functional groups were considered.
