A CMOS microprocessor for telecommunications applications (1977)

THIS REPORT will cover an 8-bit microprocessorX fabricated with a silicon-gate CMOS technology and packaged in a 40-pin DIP. It embodies several architectural innovations and an extended instruction set affording exceptional computing power. Although the fabrication technology is CMOS, it was found that the use of non-complementary structures for certain portions of the logic resulted in a device with the functional density of NMOS, but with power dissipation and internal noise margins approaching that of CMOS.
Bradykinin stimulates tumor necrosis factor and interleukin‐1 release from macrophages (1989)

Bradykinin and related kinins have been implicated in the initiation and maintenance of inflammation. Cytokines appear to be the primary mediators of many inflammatory diseases. The potential ability of bradykinin to stimulate release of tumor necrosis factor and interleukin-1 from macrophages was examined. Bradykinin stimulated release of both cytokines from P388-D1 and RAW264.7 murine macrophages. Studies with selective agonists and antagonists suggest that cytokine release is mediated by a B1 kinin receptor.
Relating microwave backscatter azimuth modulation to surface properties of the Greenland ice sheet (2006)

Abstract Azimuth dependence of a normalized radar cross-section (σº) over the Greenland ice sheet is modeled with a simple surface scattering model. The model assumes that azimuth anisotropy in surface roughness at scales of 3–300 m is the primary mechanism driving the modulation. To evaluate the contribution of azimuth anisotropy in surface roughness to the radar backscatter, the model is compared to models based on isotropic surface roughness. The models are inverted to estimate snow surface properties using σº measurements from the C-band European Remote-sensing Satellite advanced microwave instrument in scatterometer mode. Results indicate that the largest mesoscale rms surface slopes are found in the lower portions of the dry snow zone. Estimates of the preferential direction in surface roughness are highly correlated with katabatic wind fields over Greenland, which is consistent with wind-formed sastrugi as the dominant mechanism causing azimuth modulation of σº. The maximum improvement of the azimuth modulation surface model compared to its isotropic counterparts occurs in the lower regions of the dry snow zone where the azimuth variability of σº is the largest. In regions with azimuth modulation over 1 dB, the mean root-mean-square error estimate of the azimuth-dependent surface scattering model is 0.46 dB compared with 0.70 dB for similar models using isotropic roughness.
Classified vector quantization using fuzzy theory (2003)

Classified vector quantization (CVQ) is a technique for coding images that achieves good perceptual results while reducing the computational load of the process. A method that uses fuzzy theory to perform the classification involved in the CVQ technique is presented. To formulate the membership function of different categories, the concept of surface representation by triangular elements is introduced. This method yields a more natural classification scheme. The problem of determining the size of each subcodebook was also solved. The subcodebooks were built using fuzzy classifiers and the degree of accuracy of each codeword was tested by computing its fuzzy entropy. The codewords with larger fuzzy entropy were further split until an optimal point was reached.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Numerical Analysis of the Microwave Treatment of Palm Trees Infested With the Red Palm Weevil Pest by Using a Circular Array of Vivaldi Antennas (2020)

The Red Palm Weevil (RPW) is one of the most dangerous pests of palms in the world. Among several techniques that have been applied to combat the RPW pest such as phytosanitation, chemical insecticides, pheromone traps and biological control, the use of microwave energy for heat disinfestation seems to be a promoting solution. Its main advantages are rapid heat transfer, volumetric and selective heating, speed of switching on and off and no pollution to the environment. This article presents the design of microwave antenna system for microwave disinfection of date palms application. The microwave system consists of a 3-D circular array of 16 Vivaldi elements. We present an electromagnetic-thermal model, including palm and adult/Larva RPW models, to test their thermal reactions for microwave heating. The 3-D numerical model shows the capability of the microwave system to heat the outer layer of the palm, and reach the RPW lethal temperature. Also, the research discusses the effect of varying the input power and treatment duration to control the RPW. This work provides a powerful tool to simulate the thermal distribution of the palm and RPW insects for different input cases; which help fight against the RPW.
Inverse correlation between PDGFC expression and lymphocyte infiltration in human papillary thyroid carcinomas (2009)

At the mRNA level, several members of the PDGF family are differentially expressed in PTCs as compared to normal thyroid tissue. Of these, only the PDGFC mRNA expression level initially seemed to distinguish classical PTCs from the more aggressive PTCs. However, further investigation showed that PDGFC expression level correlated inversely to the expression of several lymphocyte specific genes, and to the presence of lymphocytes in the biopsies. Thus, we find that PDGFC mRNA expression were down-regulated in biopsies containing infiltrated lymphocytes or thyroiditis. No other PDGF family member could be linked to lymphocyte specific gene expression in our collection of PTCs biopsies.

Cloud classification using METEOSAT VIS-IR imagery (1992)

A new method is proposed which allows for reasonably accurate cloud classification based upon Gaussian approximation of cloud emission and using a pair of visible-infrared, high resolution METEOSAT images. Its most important characteristic is the very low amount of CPU time required for a single classification. It becomes then suitable for application in very short range weather forecasting (nowcasting) by ensuring the adequate time coverage and necessary rapidity of use for the operational environment. Two classifications of summer and winter meteorological situations are presented.
Unusual stability of human neuroglobin at low pH – molecular mechanisms and biological significance (2009)

Neuroglobin (Ngb) is a recently discovered globin that is predominantly expressed in the brain, retina and other nerve tissues of human and other vertebrates. Ngb has been shown to act as a neuroprotective factor, promoting neuronal survival in conditions of hypoxic-ischemic insult, such as those occurring during stroke. In this work, the conformational and functional stability of Ngb at acidic pH was analyzed, and the results were compared to those obtained with Mb. It was shown by spectroscopic and biochemical (limited proteolysis) techniques that, at pH 2.0, apoNgb is a folded and rigid protein, retaining most of the structural features that the protein displays at neutral pH. Conversely, apoMb, under the same experimental conditions of acidic pH, is essentially a random coil polypeptide. Urea-mediated denaturation studies revealed that the stability displayed by apoNgb at pH 2.0 is very similar to that of Mb at pH 7.0. Ngb also shows enhanced functional stability as compared with Mb, being capable of heme binding over a more acidic pH range than Mb. Furthermore, Ngb reversibly binds oxygen at acidic pH, with an affinity that increases as the pH is decreased. It is proposed that the acid-stable fold of Ngb depends on the particular amino acid composition of the protein polypeptide chain. The functional stability at low pH displayed by Ngb was instead shown to be related to hexacoordination of the heme group. The biological implications of the unusual acid resistance of the folding and function of Ngb are discussed.

Transpost: a novel approach to the display and transmission of 360 degrees-viewable 3D solid images (2006)

Three-dimensional displays are drawing attention as next-generation devices. Some techniques which can reproduce three-dimensional images prepared in advance have already been developed. However, technology for the transmission of 3D moving pictures in real-time is yet to be achieved. In this paper, we present a novel method for 360-degrees viewable 3D displays and the Transpost system in which we implement the method. The basic concept of our system is to project multiple images of the object, taken from different angles, onto a spinning screen. The key to the method is projection of the images onto a directionally reflective screen with a limited viewing angle. The images are reconstructed to give the viewer a three-dimensional image of the object displayed on the screen. The display system can present images of computer-graphics pictures, live pictures, and movies. Furthermore, the reverse optical process of that in the display system can be used to record images of the subject from multiple directions. The images can then be transmitted to the display in real-time. We have developed prototypes of a 3D display and a 3D human-image transmission system. Our preliminary working prototypes demonstrate new possibilities of expression and forms of communication.
Ultrastructural features of the haustorial apparatus of the white blister fungus Albugo candida (1975)

The small spherical haustorium of the white blister fungus is connected to the much larger haustorial mother cell by a slender cylindrical neck. The haustorium contains mitochondria with tubular cristae as well as ribosomes and occasional cisternae of rough endoplasmic reticulum. Nuclei and perinuclear dictyosomes are found in the mother cells but are absent from haustoria. No discontinuity is found in the fungal cell wall in the haustorial neck. Immediately adjacent to the fungal wall and extending through the penetration site to a point about midway along the neck is a dark-staining layer continuous with the host cell wall. A collar consisting of fibrillar material, also continuous with the host cell wall, is commonly found around the proximal portion of the neck external to this dark-staining layer. An electron-dense sheath surrounds the thin wall of the haustorial body but is absent from the neck region. A series of tubules is continuous with the invaginated host plasmalemma which surrounds the haustorial body. These tubules contain an electron-dense core similar in appearance to, and continuous with, the sheath matrix. No evidence was obtained for the involvement of host dictyosomes and their secretory vesicles in the formation of the haustorial sheath. A constant feature of the haustorial apparatus is the association of flattened cisternae of host endoplasmic reticulum with the distal portion of the haustorial neck. The significance of this finding is discussed in relation to the endomembrane concept.
Parity and column twist bit interleaver for DVB-T2 LDPC codes (2008)

We introduce a parity and column twist bit interleaver which improves performance of DVB-T2 LDPC codes in channels with erasure. The key idea is avoiding multiple bits on constellation symbols which are connected to the same check node, in order to minimize damage by an erased symbol. By simulation we observed significant performance improvement in faded erasure channels, and the higher erasure probability, the more gain we observed.
Chlorosulfonamide Salts Are Superior Electrophilic Chlorine Precursors for the Organocatalytic Asymmetric Chlorocyclization of Unsaturated Amides (2014)

Chloramine-T·3H(2)O and other chlorosulfonamide salts can serve as readily available, stable, and inexpensive precursors of electrophilic chlorine in the organocatalytic asymmetric chlorofunctionalization of olefins. In conjunction with commercially available organocatalysts, they can be utilized in the asymmetric chlorocyclization of unsaturated amides to yield products with unprecedented levels of stereoselectivity even at ambient temperatures and high concentrations.
Discovery, Optimization, and Biological Evaluation of Sulfonamidoacetamides as an Inducer of Axon Regeneration (2016)

Axon regeneration after injury in the central nervous system is hampered in part because if an age-dependent decline in the intrinsic axon growth potential, and one of the strategies to stimulate axon growth in injured neurons involves pharmacological manipulation of implicated signaling pathways. Here we report phenotypic cell-based screen of chemical libraries and structure-activity-guided optimization that resulted in the identification of compound 7p which promotes neurite outgrowth of cultured primary neurons derived from the hippocampus, cerebral cortex, and retina. In an animal model of optic nerve injury, compound 7p was shown to induce growth of GAP-43 positive axons, indicating that the in vitro neurite outgrowth activity of compound 7p translates into stimulation of axon regeneration in vivo. Further optimization of compound 7p and elucidation of the mechanisms by which it elicits axon regeneration in vivo will provide a rational basis for future efforts to enhance treatment strategies.

Effect of Nematicidal Seed Soaking on Penetration and Development of Meloidogyne Incognita in French Bean (1988)

Seed of french bean cv. Pusa Parvati were soaked in 0, 125 and 250 μg/ml solutions of carbofuran, ebuphos, triazophos and phenamiphos for 6 or 12 hours. Soaking at lowest rate for even 6 h resulted in reduced galling, larval penetration and multiplication of Meloidogyne incognita. Triazophos was the most effective chemical followed by phenamiphos which was significantly more effective than ebuphos and carbofuran.
Copper nanoclusters trigger muscle cell apoptosis and atrophy in vitro and in vivo (2015)

Copper nanoclusters (CuNCs) are increasingly being used in nanomedicine owing to their utility in cellular imaging and as catalysts. Additionally, nanotoxicology research of CuNCs is gaining attention. We report here the synthesis and characterization of CuNCs and their cytotoxic impact on muscle cells. A simple protein-directed synthesis of stable CuNCs was prepared, using bovine serum albumin as the stabling agent. Physicochemical characterization of the synthesized CuNCs was performed using transmission electron microscopy. To evaluate the in vitro cytotoxicity, C2C12 cells were exposed to increasing doses (from 0.1 to 50 µg ml(-1)) of CuNCs. CuNCs affected the viability of C2C12 cells in a dose-dependent manner, as detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and a lactate dehydrogenase release assay. Further studies indicated that CuNCs induced the formation of reactive oxygen species and decreased the activities of catalase and glutathione. CuNC treatment decreased the mitochondrial membrane potential and induced apoptosis, accompanied by an increase in the protein expression ratio of Bax/Bcl-2 and caspase-3/9 activity in C2C12 cells. CuNCs treatment resulted in atrophy of the C2C12 myotubes, which was characterized by the increased expression of atrophy-related genes, such as atrogin-1 and MuRF1. Finally, CuNCs induce morphological atrophy of primary muscle cells and mouse gastrocnemius muscle. Taken together, these results suggest that exposure to CuNCs may be a risk factor for the skeletal muscle system.
Ellipsometric measurement of the Kerr magnetooptic effect (1979)

A conventional PCSA ellipsometer has been used to measure the transverse Kerr magnetooptic effect. The ellipsometer null was first obtained, and the ellipsometric psi and Delta were determined from this measurement. Then measurements were made as a function of polarizer angle while A =+/-ø. The magnetic field applied to the sample was square wave modulated, and both the dc and the modulated light intensities were measured. dI/I was a linear function of cos/(1 +/- sinØ), where ø = Delta - 2P. The ordinate intercept and the slope of the resulting straight line were the real and imaginary parts, respectively, of dr(p)/r(p). From psi, Delta, and dr(p)/r(p) the material quantities n and Q could be calculated.
Frame-Loss-Free Optical Line Switching System for In-Service Optical Network (2009)

Fiber-to-the-home (FTTH) has now reached the stage where it is providing real-time broadband services. Since even a temporary suspension of broadcasting and telephone services cannot be permitted, it has become important to improve the reliability of FTTH network operation. We have developed an advanced optical line switching system that diverts transmission signals from an in-service line to a spare line without interrupting communication. This system is realized by equalizing the transmission times of the signals sent through dualized lines composed of an in-service line and a spare line. The transmission times are equalized by employing two techniques in the dualized lines. One is a technique that uses a free space optics system to tune the optical line length continuously. The other is a technique for measuring a wide range of time differences between signals transmitted through the dualized lines. Since the dualized lines have a Mach-Zehnder interference structure, the differences can be detected with high accuracy by employing dual-light interferometry. We applied this switching system to a gigabit Ethernet passive optical network (GE-PON) during transmission and succeeded in switching in-service lines without inducing any frame loss.
BED-REST (BR) ENHANCES CALF VASODILATOR RESPONSE TO SALINE INFUSION (SI) INDUCED CENTRAL HYPERVOLEMIA 1031 (1996)

Orthostatic intolerance following spaceflight or bedrest (BR) deconditioning may be due to inadequate vasoconstriction or inappropriate reflex vasodilation. The aim of this study was to test the hypothesis that the calf vasodilator response to increases in pulmonary capillary wedge pressure(PCWP) and right atrial pressure (RAP) produced by SI (100ml/min) is potentiated following BR. Eleven volunteers (age: 24±2 yrs, Wt:78±3kg, Ht:176±3cm) completed the experiments prior to (Pre) and following (Post) 2-weeks of -6° head-down tilt BR in which cardiac filling pressure (Swan-Ganz), calf blood flow (CBF, plethysmography) and mean arterial pressure (MAP, Finapres) were measured. BR significantly decreased baseline PCWP (pre vs post: 13.2 ± 1.0 vs 10.5 ± 1.1mmHg), RAP(7.9 ± 0.8 vs 6.2 ± 0.8 mmHg), CBF (2.3 ± 0.2 vs 1.7± 0.1 ml/dl/min), and increased MAP (85 ± 2 vs 91 ± 3 mmHg) and calf vascular resistance (CVR, 37 ± 4 vs 51 ± 3 PRU) calculated from the ratio (MAP-RAP)/CBF, SI with 15 or 30 ml/kg significantly increased PCWP, RAP, CBF, and decreased CVR both pre- and post-BR (seetable). MAP was not significantly changed by SI pre- or post-BR. In terms of per unit ▵PCWP or ▵RAP, ▵CVR was significantly greater in post- than pre-BR (-2.4 ± 0.0 or -3.9 ± 0.1 vs -2.0 ± 0.1 or-2.9 ± 0.2 PRU/mmHg). Conclusion: peripheral vasodilation in response to central hypervolemia appears to be augmented following BR deconditioning.
Analyzing application private information leaks with privacy Petri Net (2012)

Private information leak has been discovered in many applications and has become serious and challenging problem to cyber security. Previous works are based on two categories of road map, the one focuses on the outbound network traffic of application, the other one dives into the inside information flow of application. We incorporate application dynamic behavior analysis with network traffic analysis and present abstract model called Privacy Petri Net (PPN) which is more applicable to various applications and more meaningful to users. We apply our approach on both real world regular application and malware. The experiment result shows that our approach can effectively find categories, content, source and destination of the private information leaks for the target application.
