Chemical Vapor Deposition of Silicate Glasses for Use with Silicon Devices (1970)

Chemical, dielectric, thermal, and optical properties of glass films synthesized by chemical vapor reactions from the hydrides are discussed. The binary borosilicate glasses deposited at low temperature from silane, diborane, and oxygen require a thermal densification to approach bulk glass properties. The rate of densification in the temperature range of 770°–800°C is very rapid but water vapor has an accelerating influence, allowing densification at reasonable rates at temperatures as low as 450°C. The thermal expansion match with silicon was sufficiently close to allow the crack‐free coating of wafers with 12µ of glass. Borosilicate films of 5µ thickness on silicon withstood severe thermal shock, temperature cycling, moisture penetration, and corrosion resistance tests. Densified borosilicate of typical compositions had a dielectric constant of 3.8–4.1 and a dissipation factor at 103 Hz of 0.10–0.15. The d‐c dielectric field strength sustained by MIS capacitors made from 1µ thick densified films measured before and after a 1‐yr exposure to room air, was . The properties of vapor‐deposited phosphosilicate glasses and of glasses containing the oxides of aluminum and zinc are briefly described.
Chromatin and microtubule organization during premeiotic, meiotic and early postmeiotic stages of <i>Drosophila melanogaster</i> spermatogenesis* (1994)

Larval and pupal testes of Drosophila melanogaster were fixed with a methanol/acetone fixation procedure that results in good preservation of cell morphology; fixed cells viewed by phase-contrast optics exhibit most of the structural details that can be seen in live material. Fixed testis preparations were treated with anti-tubulin antibodies and Hoechst 33258 to selectively stain microtubules and DNA. The combined analysis of cell morphology, chromatin and microtubule organization allowed a fine cytological dissection of gonial cell multiplication, spermatocyte development, meiosis and the early stages of spermatid differentiation. We placed special emphasis on the spermatocyte growth phase and the meiotic divisions, providing a description of these processes that is much more detailed than those previously reported. In addition, by means of bromo-deoxyuridine incorporation experiments, we were able to demonstrate that premeiotic DNA synthesis occurs very early during spermatocyte growth.
Catalytic Stereoselective Synthesis of Pyrimidine 2-Deoxyribonucleosides (1996)

Abstract Highly stereoselective synthesis of β-d-deoxyribonucleosides from 1-O-acetyl-5-O-benzyl-2-deoxy-3-diethylthiocarbamoyl ribofuranoside (3) is performed by the reaction with silylated pyrimidine nucleobases in the presence of a catalytic amount of several Lewis acids.
Non reciprocal writing and chirality in femtosecond laser irradiated silica (2008)

We ascertain by measuring the surface topography of a cleaved sample in which damage lines have been written in volume by scanning with a femtosecond laser, that matter shearing occur along the laser track with alternating sign (scissor or chiral effect). We note that the shearing in the head of the laser tracks change its sign with the change in scanning direction (pen effect or non reciprocal writing). We also show that nanostructures in the head are nano-shearing, with all the same sign whatever the direction of writing may be. We suggest that symmetries revealed by the shearing mimic the laser induced electron plasma density structures and inform on their unusual symmetries induced by the laser beam structures.
Solid-state fermentation of cornmeal with the basidiomycete Ganoderma lucidum for degrading starch and upgrading nutritional value (2005)

After SSF by G. lucidum, the digesting and absorbing ratio of cornmeal was strikingly increased and some active substances originated from G. lucidum remained in the fermented product. This implied that cornmeal could be processed into many kinds of special functional foods by SSF of G. lucidum.

Insecure JavaScript Detection and Analysis with Browser-Enforced Embedded Rules (2010)

The JavaScript language is an interpretive programming language which is used to enhance the client-side interactivity and functionality. However, it has been much exploited by malicious parties to launch browser-based security attacks. Currently there are many security vulnerabilities assessment tools, and browsers provide sand-boxing mechanisms to protect the JavaScript code from compromising the security of the client's environment, but, unfortunately, nowadays the attacks against web applications often take advantage of the browser's own function to carry out attacks. Based on the above problems, we put forward an approach to solve the problem that is based on monitoring JavaScript code execution to detect malicious code behavior and we don't need to carry out the static analysis of JavaScript code, just compare the execution to high-level inspection rules. While visiting the website we insert the security inspection rules into the website to analyze the potential safety hazard.
Technetium(V) and rhenium(V) complexes with N-(2-mercaptophenyl)salicylideneiminate. Crystal structure of chloro(oxo)[N-(2-sulphidophenyl)salicylideneiminato-NOS]technetium(V) (1987)

The reactions of the tridentate Schiff-base ligand derived from salicylaldehyde and o-aminothio-phenol (H2L1) with [MOCl4]–(M = Tc or Re) have been investigated. The complexes [MOCl(L1)], [ReOCl2(L1)]–, and [ReOCl(X)(L1)](X = MeOH or EtOH) were synthesized and characterized by elemental analysis, i.r., 1H n.m.r., and u.v.–visible spectroscopy, mass spectrometry, magnetic susceptibility, conductivity, and thermogravimetric measurements and the complete configurations of the complexes were determined. X-Ray crystallographic investigation on [TcOCl(L1)] shows the molecular structure to be a distorted square pyramid having the ligand L1 in the equatorial plane with respect to TcO. The molecule is in the monoclinic space group P21/a, with a= 14.255(9)b= 12.495(7), c= 7.865(6)Å, β= 105.22(5)°, and Z= 4. The structure has been refined to R= 0.068 for 2 184 observed reflections. The reactions of [MOCl(L1)](M = Tc or Re) or [ReOCl(X)(L1)](X = MeOH or EtOH) with the bidentate Schiff-base ligands (HL) salicylideneimine (HL3), N-methylsalicylideneimine (HL4), N-phenylsalicylidene-imine (HL5), N-(2-hydroxyphenyl)-p-nitrobenzylideneimine (HL6), quinolin-8-ol (Hquin), quinoline-8-thiol (Htquin), and N-(2-mercaptophenyl)-p-nitrobenzylideneimine (HL7) lead to the ‘mixed’ compounds [MO(L1)(L)]. The products with L = tquin or L7 were obtained only for [ReOCl(X)(L1)](X = MeOH or EtOH). All these complexes were characterized by the physicochemical techniques listed above.
Synthesis of a C4-<i>e</i><i>pi</i>-C1−C6 Fragment of FR901464 Using a Novel Bromolactolization (2004)

A synthesis of a C4-epi-C1−C6 fragment of the antitumor agent FR901464 is reported. The advanced intermediate prepared in this study contains two of the three correct stereocenters found in the C1−C6 moiety of FR901464. For the preparation of this intermediate, we have developed a highly diastereoselective bromolactolization of a δ-alkenyl ketone.
Morphologic Effect of Dimethyl Sulfoxide on the Blood-Brain Barrier (1982)

Dimethyl sulfoxide (DMSO) opens the blood-brain barrier of mice to the enzymatic tracer horseradish peroxidase. A single injection of horseradish peroxidase in 10 to 15 percent DMSO into the tail vein along with 10 to 15 percent DMSO delivered intraperitoneally allowed horseradish peroxidase to fill the extracellular clefts throughout the brain within 2 hours. In the absence of DMSO, peroxidase failed to enter brain parenchyma except through the circumventricular organs. Opening of the blood-brain barrier by DMSO is reversible. Dimethyl sulfoxide stimulated the pinocytosis of horseradish peroxidase by the cerebral endothelium; the peroxidase was then directed to lysosomal dense bodies for degradation. Vesicular transport of horseradish peroxidase from the luminal to the abluminal wall of the endothelial cell was not observed. Dimethyl sulfoxide did not alter the morphology of endothelial cells or brain parenchyma.
Bone Morphogenetic Protein (BMP)-2 Induces Apoptosis in Human Myeloma Cells (2002)

BMPs (bone morphogenetic proteins), members of the transforming growth factor (TGF)-beta superfamily, are a group of related proteins which are capable of inducing the formation of cartilage and bone, but are now regarded as multifunctional cytokines. However, little is known about their role in hematopoiesis. Recently, we found a novel function of BMPs to hematopoietic cells in that BMP-2 induces apoptosis not only in human myeloma cell lines, but also in primary samples from patients with multiple myeloma in vitro. BMP-2 caused cell cycle arrest in the G1 phase which was associated with accumulation of p21CIP1/WAF1 and p27KIP1, and the subsequent apoptosis of myeloma cells. Further analysis showed that BMP-2 induced down-regulation of Bcl-X(L) through the inactivation of STAT3, resulting in the induction of apoptosis in myeloma cells. We conclude that BMP-2 may have the potential to be one of the novel therapeutic agents for treatment in patients with multiple myeloma because of the beneficial effects on both myeloma cells and bone diseases. In this review, we summarize data concerning BMPs and BMP-2-induced apoptosis of myeloma cells including our own recent experimental data.

Dynamic changes in translational efficiency are deduced from codon usage of the transcriptome (2012)

Translation of a gene is assumed to be efficient if the supply of the tRNAs that translate it is high. Yet high-abundance tRNAs are often also at high demand since they correspond to preferred codons in genomes. Thus to fully model translational efficiency one must gauge the supply-to-demand ratio of the tRNAs that are required by the transcriptome at a given time. The tRNAs' supply is often approximated by their gene copy number in the genome. Yet neither the demand for each tRNA nor the extent to which its concentration changes across environmental conditions has been extensively examined. Here we compute changes in the codon usage of the transcriptome across different conditions in several organisms by inspecting conventional mRNA expression data. We find recurring dynamics of codon usage in the transcriptome in multiple stressful conditions. In particular, codons that are translated by rare tRNAs become over-represented in the transcriptome in response to stresses. These results raise the possibility that the tRNA pool might dynamically change upon stress to support efficient translation of stress-transcribed genes. Alternatively, stress genes may be typically translated with low efficiency, presumably due to lack of sufficient evolutionary optimization pressure on their codon usage.

Reactive navigation in dynamic environment using a multisensor predictor (1999)

A reactive navigation system for an autonomous mobile robot in unstructured dynamic environments is presented. The motion of moving obstacles is estimated for robot motion planning and obstacle avoidance. A multisensor-based obstacle predictor is utilized to obtain obstacle-motion information. Sensory data from a CCD camera and multiple ultrasonic range finders are combined to predict obstacle positions at the next sampling instant. A neural network, which is trained off-line, provides the desired prediction on-line in real time. The predicted obstacle configuration is employed by the proposed virtual force based navigation method to prevent collision with moving obstacles. Simulation results are presented to verify the effectiveness of the proposed navigation system in an environment with multiple mobile robots or moving objects. This system was implemented and tested on an experimental mobile robot at our laboratory. Navigation results in real environment are presented and analyzed.

Abstract Samsung SDI has developed a full color 5.0″ WVGA AMOLED display using top emission structure with a super fine pitch of 0.1365 mm 186 ppi, the world's highest density OLED display ever reported to date. Scan driver circuits and demux circuits were integrated within the display panel, using low temperature poly‐Si TFT CMOS technologies, and data driver circuits were mounted using COG IC. Peak luminescence was greater than 300 cd/ with power consumption of 500 mW with 30% of the pixels on.
Characterization of Growth and Differentiation in a Telomerase-Immortalized Human Corneal Epithelial Cell Line (2005)

hTCEpi cells stratify, differentiate, and desquamate similar to normal human corneal epithelium. Further study of the hTCEpi cell line may be valuable in studying the molecular mechanisms regulating corneal epithelial cell differentiation and desquamation.
Expression of osteoclast differentiation factor in rheumatoid arthritis (2000)

The present results suggest that activated RASF, by expressing ODF, play an important role in rheumatoid bone destruction. Moreover, the data provide evidence that RASF not only activate osteoclasts, but also contribute directly to osteoclastogenesis.
Glycopeptides Related to β-Endorphin Adopt Helical Amphipathic Conformations in the Presence of Lipid Bilayers (2005)

A series of glycosylated endorphin analogues designed to penetrate the blood-brain barrier (BBB) have been studied by circular dichroism and by 2D-NMR in the presence of water; TFE/water; SDS micelles; and in the presence of both neutral and anionic bicelles. In water, the glycopeptides showed only nascent helix behavior and random coil conformations. Chemical shift indices and nuclear Overhauser effects (NOE) confirmed helices in the presence of membrane mimics. NOE volumes provided distance constraints for molecular dynamics calculations used to provide detailed backbone conformations. In all cases, the glycopeptides were largely helical in the presence of membrane bilayer models (micelles or bicelles). Plasmon waveguide resonance (PWR) studies showed hen egg phosphatidyl choline (PC) bilayers produce amphipathic helices laying parallel to the membrane surface, with dissociation constants (K(D)) in the low nanomolar to micromolar concentration range. Two low-energy states are suggested for the glycosylated endorphin analogues, a flexible aqueous state and a restricted membrane bound state. Strong interactions between the glycopeptide amphipaths and membranes are crucial for penetration of the BBB via an endocytotic mechanism (transcytosis).

datagram service.
Advances in magnetic resonance imaging of brain tumours. (2003)

Advances in MRI techniques are providing better diagnostic and therapeutic information, but can only ever be a surrogate marker of physiological and pathological processes; until it can routinely be used to image the brain at a cellular level, MRI will always be secondary to pathology in the final diagnostic evaluation.

Spotting recognition of head gestures from color image series (2002)

Presents an approach for spotting recognition of human head gestures from color image series. First, we use an algorithm based on a perceptually uniform color system to detect skin color region and hair color region of the face from input images. Then, the 3D pose of the head relative to the camera is estimated by calculating the primary moment and secondary moment of the skin color region and the hair color region. The standard patterns of each gesture were represented by the sequence of rotation angles in X, Y, Z axis, and the head area. Moreover the human head gestures were recognized by using the continuous dynamic programming algorithm to compare input image series with the standard patterns. Extensive experiments show the effectiveness of this approach in the human head gestures recognition from live video sequences with different people even wearing glasses, with different head size, and with unknown complex background.

Hybrid Core–Shell Microspheres from Coassembly of Anthracene-Containing POSS (POSS-AN) and Anthracene-Ended Hyperbranched Poly(ether amine) (hPEA-AN) and Their Responsive Polymeric Hollow Microspheres (2013)

We demonstrated a novel core–shell microsphere (CSM) fabricated from coassembly of anthracene-ended hyperbranched poly(ether amine) (hPEA-AN) and anthracene containing polyhedral oligomer silsesquioxane (POSS-AN). The obtained CSMs are cross-linked through photodimerization of anthracene and possess the well-defined core–shell structure according to the images of SEM, TEM, and AFM. The shell of the obtained CSM is comprised of hPEA-AN, while POSS-AN prefers the ordered crystallized aggregation in the core. The size of the obtained CSMs is uniform and tunable. With the increasing content of hPEA-AN in the coassembly, the diameter of CSMs decreased from 930 to 616 nm, while the thickness of shell increased from 95 to 170 nm. Moreover, polymeric hollow microsphere (PHM) was prepared by removing the POSS-AN core of CSM in hydrofluoric acid (HF). The obtained PHM is amphiphilic and fluorescent, and its size is responsive to environmental stimulus such as temperature and pH. PHM can be used in the encapsulation and controlled release of guest molecules. Moreover, the controlled release of guest molecules from PHM can be monitored by itself fluorescence change.
Mycorrhizae, mycorrhizospheres, and reforestation: current knowledge and research needs (1987)

Although not a panacea, management of mycorrhizae and associated organisms is an important reforestation aid. Its three major components are protection of the indigenous soil community and evaluation of inoculation needs, integration of inoculation programs into existing reforestation technology, and research. Clear-cutting frequently results in reduced mycorrhizae formation, particularly when reforestation is delayed and no other host plants are present to maintain fungal populations. Implications of such reductions for reforestation vary with environmental factors and tree species. Adequate mycorrhiza formation is especially critical for ectomycorrhizal trees growing on poor soils or in environments where seedlings must establish quickly to survive. It may also be important where early successional, noncrop plants do not support the same mycobiont as the crop. In such circumstances, a self-reinforcing trend may develop, with poor mycorrhiza formation reducing seedling survival and poor tree stocking leading to further loss of mycorrhizal inocula. Inoculating nursery seedlings with mycobionts holds promise for improving outplanting performance only if site-adapted fungi are used. A practical alternative is to improve nursery practices to enhance natural populations of mycorrhizal fungi. Seedlings leaving the nursery with diverse mycorrhizae may perform better than those leaving with only one or a few nursery-adapted types. Research is needed in three broad areas: on adaptations of mycorrhizal fungi to particular environmental factors; on interactions between tree seedlings and processes occurring within the sphere of influence of roots (the rhizosphere) or of mycorrhizal roots (the mycorrhizosphere); and on the role of mycorrhizae and associated organisms in ecosystem structure and processes, particularly nutrient cycling, plant-plant interaction, and soil structure.
High-speed polarization scrambler with adjustable phase chirp (1996)

We report on the operation and performance of a novel electrooptic polarization scrambler that is capable of generating any desired combination of optical phase and polarization modulation. The scrambler comprises a dual-drive Mach-Zehnder-type intensity modulator on lithium niobate and an external microoptic polarization splitter which combines the two complementary outputs of the integrated-optic intensity modulator in orthogonal polarization states. The modulation indexes of the sinusoidal phase and polarization modulation in the output light can be varied independently of each other via the amplitudes and phases of the two drive voltages to the Mach-Zehnder modulator. The scrambler has a 3-dB modulation bandwidth of 14 GHz and operates in the 1.5-1.6-/spl mu/m wavelength range with an overall fiber-to-fiber insertion loss of less than 5 dB. At 5 GHz modulation frequency and electric drive powers between 390-2030 mW, we demonstrate phase-chirped and chirp-free depolarization with a residual degree of polarization of less than 0.02 and continuously variable phase modulation to 2.3-rad peak phase deviation.
The Problem of Speed Measurements in the Slip-Slide Control for Electric Railway Traction (2006)

The phenomena of slip or slide, more or less present in railway traction, have negative economical and technical effects. The key element of the anti-slip or anti-slide systems is the accuracy of the wheels and/or locomotive-body speed measurement. The paper analyzes some methods known in the literature and analysis the effect of speed measurement errors on the anti-slip system performances
