Improved Retention Time in Twin Gate 1T DRAM With Tunneling Based Read Mechanism (2016)

We report a twin gate tunnel field effect transistor-based capacitorless dynamic memory with improved retention characteristics through well-calibrated simulations. The first front gate of the twin gate architecture regulates the read mechanism based on band-to-band tunneling whereas the second front gate creates and maintains a dedicated volume for the charge storage near the drain region. The profound well along with the optimized bias values aid to attain a retention time (RT) of ~1.5 s at 85°C. Systematic analysis shows that the storage region can be scaled down to 50 nm with further improvement in RT by using an underlap region between drain and second gate. Optimally designed twin gate device exhibits an improved RT at higher temperature (125°C).

Compartmentalization of Intraalveolar and Systemic Lipopolysaccharide-Induced Tumor Necrosis Factor and the Pulmonary Inflammatory Response (1989)

Tumor necrosis factor-alpha (TNF), a monokine produced by lipopolysaccharide (LPS)-stimulated macrophages, is an activator of phagocytic functions and may modulate host responses during infection. To determine the effects of LPS on TNF activity and the pulmonary inflammatory response in vivo, we challenged rats systemically or intratracheally with LPS. Intravenous LPS significantly increased serum TNF content from nondetectable levels in control specimens to peak levels at 90 min, which declined to baseline by 3 h. In response to intratracheal LPS, levels of TNF both in bronchoalveolar lavage fluid and associated with alveolar macrophages increased significantly from near nondetectable levels in control animals. Increases in TNF levels were confined to the LPS-challenged compartment. Intravenous LPS resulted in a decrease in the number of peripheral blood neutrophils and in sequestration of these cells within the pulmonary vasculature. In contrast, intratracheal LPS elicited a marked intraalveolar inflammatory response.
Transforming growth factor-β1 polymorphisms and graft-versus-host disease risk: a meta-analysis (2015)

Some studies have demonstrated that transforming growth factor (TGF)-β polymorphisms may have an important role in the pathological process of graft-versus-host disease (GVHD). However, the results are not consistent. Thus, we performed a meta-analysis. Online databases were searched to obtain relevant articles published up until May 2015. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of associations. Donors (OR=0.56; 95%CI, 0.32-0.98; P=0.04) and recipients (OR=0.73; 95%CI, 0.63-0.85; P<0.0001) with TGF-β1 rs1800469 polymorphism showed decreased GVHD risk, respectively. Donors with TGF-β1 rs1800470 polymorphism were also observed to have lower GVHD risk (OR=0.65; 95%CI, 0.46-0.94; P=0.02). However, TGF-β1 rs1800470 polymorphism in recipients was not associated with GVHD risk (OR=1.28; 95%CI, 0.81-2.01; P=0.29). No significant heterogeneity was found in the meta-analysis. This meta-analysis suggests that donors or recipients with TGF-β1 rs1800469 polymorphism and donors with TGF-β1 rs1800470 polymorphism might be associated with reduced GVHD risk.
Test of the Linear-No Threshold Theory of Radiation Carcinogenesis for Inhaled Radon Decay Products (1995)

Data on lung cancer mortality rates vs. average radon concentration in homes for 1,601 U.S. counties are used to test the linear-no threshold theory. The widely recognized problems with ecological studies, as applied to this work, are addressed extensively. With or without corrections for variations in smoking prevalence, there is a strong tendency for lung cancer rates to decrease with increasing radon exposure, in sharp contrast to the increase expected from the theory. The discrepancy in slope is about 20 standard deviations. It is shown that uncertainties in lung cancer rates, radon exposures, and smoking prevalence are not important and that confounding by 54 socioeconomic factors, by geography, and by altitude and climate can explain only a small fraction of the discrepancy. Effects of known radon-smoking prevalence correlations--rural people have higher radon levels and smoke less than urban people, and smokers are exposed to less radon than non-smokers--are calculated and found to be trivial. In spite of extensive efforts, no potential explanation for the discrepancy other than failure of the linear-no threshold theory for carcinogenesis from inhaled radon decay products could be found.
Latex Immunoagglutination Assays (2005)

Latex immunoagglutination assays continue to be widely used in biology and medicine for the detection of small quantities of an antibody or antigen of interest in fluid test samples. Main characteristics of preparation and use of these assays are examined here. Physical adsorption of proteins onto latex particles surface, with special relevance to immunoglobulins, is analyzed with major attention to those factors that influence adsorption: medium conditions such as pH and ionic strength, surface characteristics as type and amount of charge, or hydrophobicity. Different functionalized latexes for covalent linking are also presented, as well as the corresponding chemical reactions. Techniques for the detection and quantification of the immunoreaction are briefly summarized, including visual observation, light scattering, turbidimetry, nephelometry, and angular anisotropy. Finally, some problems of colloidal stability of these latex assays are analyzed, as well as the different solutions applied by scientists to solve them.
Boosting capacities with chemicals (1973)

From the first moment of operation, fouling and corrosion products interfere with flow passages and heat transfer surfaces of process plants. Chemistry has become the maintenance man's friend. Chemical cleaning technology has evolved rather steadily during the past 30 yr, until the most interesting developments now allow plant equipment to be maintained with less corrosion danger and less downtime. Today, periodic cleaning and restoring is part of the job of preventive maintenance. One important use of chemical cleaning is on new plant equipment, to remove the dirt and scale of fabriction. The cleaning method most often proposed historically was the application of strong mineral acids. Even today, although there is a trend toward techniques that take advantage of less corrosive agents, particularly the chelants, hydrochloric acid remains cheap and effective. Tabular data provide the characteristics of chemical cleaning compounds.
Integration of e^(x^n) and e^(-x^n) in forms of series, their applications in the field of differential equation and in introducing generalized form of Skewness and Kurtosis (2008)

In this paper we tried a different approach to work out the integrals of e^(x^n) and e^(-x^n). Integration by parts shows a nice pattern which can be reduced to a form of series. We have shown both the indefinite and definite integrals of the functions mentioned along with some essential properties e.g. conditions of convergence of the series. Further more, we used the integrals in form of series to find out series solution of differential equations of the form x[(d^2 y)/(dx^2)]-(n-1)(dy/dx)-n^2 x^(2n-1)y-nx^n=0 and x[(d^2 y)/(dx^2)] -(n-1)(dy/dx)-n^2x^(2n-1)y+(n-1)=0, using some non standard method. We introduced modified Normal distribution incorporating some properties derived from the above integrals and defined a generalized version of Skewness and Kurtosis. Finally we extended Starling's approximation to limit [n to infinity ] (2n)! ~ 2n * \sqrt{(2\pi)} [(2n/e)]^(2n).
Application of discrete event simulation in production scheduling (2002)

The article describes the application of discrete event simulation in a process industry (coffee manufacturing) as a daily production scheduling tool. A large number of end products (around 300), sporadic demand, and limited shelf life of coffee (90 days) make it difficult to generate feasible production schedules manually. To solve this problem, an integrated system was developed incorporating discrete event simulation methodology into the scheduling process. The integrated system is comprised of two components: a scheduling program and a simulation model. The scheduling program is used to generate daily schedules for roasting, grinding, and packing coffee. The simulation model uses the generated schedules to simulate the production of coffee and regenerates a modified production schedule. Each of the components are described in detail, evaluated in terms of performance factors, and validated with a set of real production data. Although the article focuses on a specific system, we share our experiences and intuitions gained and encourage other process industries to develop simulation based scheduling tools.

Diffusion-weighted and diffusion tensor imaging of the brain, made easy (2010)

Diffusion-weighted and diffusion tensor imaging (DWI/DTI) has revolutionized clinical neuroimaging. Pathology may be detected earlier and with greater specificity than with conventional magnetic resonance imaging sequences. In addition, DWI/DTI allows exploring the microarchitecture of the brain. A detailed knowledge of the basics of DWI/DTI is mandatory to better understand pathology encountered and to avoid misinterpretation of typical DWI/DTI artifacts. This article reviews the basic physics of DWI/DTI exemplified by several classical clinical cases.
Electric current in dc surface flashover in vacuum (1999)

Dielectric surface flashover in vacuum is characterized by a three-phase development, as shown by current measurements covering the range from 10−4 to 100 A, assisted by x-ray emission measurements, high speed photography, and time-resolved spectroscopy. Further information is gained from a comparison of the flashover dynamics at 77 and 300 K. Phase one comprises a fast (several nanoseconds) buildup of a saturated secondary electron avalanche reaching current levels of 10 to 100 mA. Phase two is associated with a slow current amplification, with a duration on the order of 100 ns, reaching currents in the ampere level. The final phase three is characterized again by a fast (nanoseconds) current rise up to the impedance-limited current on the order of 100 A in this specific apparatus. The development during phase two and three is described by a zero-dimensional model, where electron-induced outgassing leads to a Townsend-like gas discharge above the surface. The feedback mechanism towards a self-sustained discharge is due to space charges leading to an enhanced field emission from the cathode. A priori unknown model parameters, such as field enhancement factors, outgassing rate, and the buildup of the gas density above the surface, are determined by fitting calculated results to experimental data.
A 2 GHz and 5GHz dual-band direct conversion RF frontend for multi-standard applications (2005)

A dual-band direct conversion receiver front-end is designed in 0.18 mum CMOS process. It is composed of two LNAs and a dual-band mixer. A dual-band mixer uses the switched inductor matching network to select the bands such as 2 GHz and 5 GHz band. Two LNAs are switched according to the operation frequency, and the gain is controlled for multi-standard capability; thus it can be applied to a multi-standard transceiver that covers WCDMA and 802.11a/b/g
Synthesis and Contractile Activity of Substituted 1,2,3,4-Tetrahydroisoquinolines (2011)

A series of different 1-monosubstituted and 1,1-disubstituted 1,2,3,4-tetrahydro-isoquinolines was synthesized in high yields from different ketoamides. We have developed a convenient method for the synthesis of disubstituted derivatives by interaction of ketoamides with organomagnesium compounds, followed by cyclization in the presence of catalytic amounts of p-toluenesulfonic acid (PTSA). A number of substituents at the C-1 in the isoquinoline skeleton were introduced varying either carboxylic acid or organomagnesium compound. Some of the obtained 1,1-dialkyl-1,2,3,4-tetrahydro-isoquinolines possess contractile activity against guinea pig's gastric smooth muscle preparations.
Layer-by-Layer Self-Assembly Construction of Highly Ordered Metal-TiO<sub>2</sub> Nanotube Arrays Heterostructures (M/TNTs, M = Au, Ag, Pt) with Tunable Catalytic Activities (2012)

We have developed a facile and easily accessible layer-by-layer (LBL) self-assembly route to synthesize hierarchically ordered M/TNTs (M = Au, Ag, Pt) heterostructures. These integrated heterostructures show remarkably enhanced photoactivity and outstanding photostability; photoelectrochemical exploitations substantiated the contribution role of metal NPs acting as “electron reservoir” in prolonging the lifetime of photogenerated electron–hole charge carriers. In addition, these well-defined self-assembled hybrid systems can also be used as a promising catalyst for recycled selective catalytic reduction of 4-nitrophenol toward 4-aminophenol. The integration of high photoactivity and efficient catalytic reduction properties of the heterostructures lies crucially on the LBL self-assembly-induced monodispersivity of metal NPs on the framework of TNTs, and, particularly, the intimate interfacial contact between metal NPs and TNTs substrate arising from the pronounced electrostatic attractive interaction afforded by polyelectrolytes multilayering. Our results show that the design and utilization of highly ordered metal/1-D semiconductor hybrid nanostructures based on the facile LBL self-assembly strategy can find diverse catalytic applications.
SPARC Participates in the Branching Morphogenesis of Developing Fetal Rat Lung (1995)

Adhesion of cells to components of the extracellular matrix has been shown to be critical in normal lung development, particularly during the pseudoglandular stage, when conducting airways are forming through a process of branching morphogenesis. Expression of factors that inhibit cellular adhesion might also modulate branching morphogenesis. SPARC is a secreted glycoprotein that exhibits antiadhesive effects on cultured cells and is widely expressed in embryonic tissues. In this report, we examine the distribution of SPARC in fetal rat lung during development and its effect on the process of branching morphogenesis. Immunohistochemistry and in situ hybridization studies revealed that SPARC was present in the airway epithelial cells during the pseudoglandular stage of lung development, and in blood vessels and smooth muscle cells associated with airways during the canalicular and saccular stages of development. We used an in vitro model of rat lung branching morphogenesis to examine airway branching in the presence of: a) a neutralizing anti-SPARC antibody; or b) a synthetic peptide from a region of SPARC that, like the native protein, perturbs cell adhesion and diminishes the synthesis of fibronectin and thrombospondin 1. Lungs cultured in the presence of either reagent exhibited diminished branching and an abnormal morphology that was characterized in part by dilated airways. These findings implicate SPARC in the development of the airways.
Near-optimal low complexity joint estimation of cochannel ISI signals for mobile receivers (2003)

Cochannel interference affects not only the signal quality, but also the capacity of most wireless cellular networks. Unlike in spread spectrum communications, in systems employing nonspread signals, cochannel signal suppression is expensive. Moreover, at the portable station, joint estimation rather than suppression of the cochannel signal(s) may be a cheaper alternative and may often-times also provide a better signal quality. In this work we propose a novel two-stage joint Viterbi algorithm with full feedback. This technique, which is sub-optimal to the ideal joint maximum likelihood sequence estimator, provides an excellent way to trade complexity for performance, and is amenable for single-input mobile and hand-held receiver implementations.
Management (1996)

Once upon a time, there was a magician's closet. It was filled with all sorts of wonders. The problem was that nobody knew exactly what was in the closet, and anyone brave enough to open the door risked having a cascade of bowling balls, snow shoes, Ouija boards, and Erlenmeyer flasks come down on his head. This closet, metaphorically speaking, was Dow Chemical's patent archive—a disorganized mess of intellectual capital. In recent years, Dow undertook the necessary task of putting the closet in order, and thus entered the nebulous world of knowledge management.
<i>N</i>-Hydroxy-<i>N</i>-<i>o</i>-tolylacetamide (2008)

In the mol-ecule of the title compound, C(9)H(11)NO(2), the methyl C atom bonded to the ring and the N atom lie in the benzene ring plane. An intra-molecular O-H⋯O hydrogen bond results in the formation of a five-membered planar ring, which is oriented at a dihedral angle of 81.37 (3)° with respect to the benzene ring. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules stacked along the b axis. There are also π-π inter-actions between benzene rings with a face-to-face stacking distance of 3.434 Å.
Glioma cell influence on cerebral endothelial cell Na(+)-K(+)-ATPase. (1990)

Using in vitro techniques, we have shown that astrocytes do not increase the ouabain-sensitive Na(+)-K(+)-ATPase activity in cerebral endothelial cells. However, malignant astrocytoma cells when co-cultured with cerebral endothelial cells significantly enhance ouabain-sensitive Na(+)-K(+)-ATPase activity in cerebral endothelial cells. Also, Na(+)-K(+)-ATPase activity in cerebral endothelial cells co-cultured with malignant astrocytoma cells is inhibited by corticosteroids to the same degree as ouabain. These results suggest that brain edema associated with malignant glioma may in part be due to an increase in ouabain-sensitive Na(+)-K(+)-ATPase activity at the blood-brain barrier and that the antiedema effects of corticosteroids may be due to a reduction in the activity of this enzyme.

Quasicrystals and icosians (1993)

A family of quasicrystals of dimensions 1, 2, 3, 4 governed by the root lattice E8 is constructed. The use of the icosian ring, found in the quaternions with coefficients in Q( square root 5), allows simultaneous interpretation of the construction both in physical space and as a result of the standard 'cut-and-projection' method in double dimension. Icosians are seen to provide a natural co-ordination scheme for these quasicrystals. Nested sequences of quasicrystals form systems whose symmetries are all derivable from inflational and reflective symmetries directly related to the arithmetic of the icosians. The use of Coxeter diagrams clarifies the amazing relationship of E8 and quasicrystal symmetries and leads to the fundamental chain E8 contains/implies D6 contains/implies A4 contains/implies A1*A1 that underlies five-fold symmetry in quasicrystals. Decomposition of quasicrystals into concentric shells and a counting formula for the cardinalities of these shells is discussed.
Spatial Optimization of Agricultural Land Use Based on Cross-Entropy Method (2017)

An integrated optimization model was developed for the spatial distribution of agricultural crops in order to efficiently utilize agricultural water and land resources simultaneously. The model is based on the spatial distribution of crop suitability, spatial distribution of population density, and agricultural land use data. Multi-source remote sensing data are combined with constraints of optimal crop area, which are obtained from agricultural cropping pattern optimization model. Using the middle reaches of the Heihe River basin as an example, the spatial distribution of maize and wheat were optimized by minimizing cross-entropy between crop distribution probabilities and desired but unknown distribution probabilities. Results showed that the area of maize should increase and the area of wheat should decrease in the study area compared with the situation in 2013. The comprehensive suitable area distribution of maize is approximately in accordance with the distribution in the present situation; however, the comprehensive suitable area distribution of wheat is not consistent with the distribution in the present situation. Through optimization, the high proportion of maize and wheat area was more concentrated than before. The maize area with more than 80% allocation concentrates on the south of the study area, and the wheat area with more than 30% allocation concentrates on the central part of the study area. The outcome of this study provides a scientific basis for farmers to select crops that are suitable in a particular area.
Programmability in DDD Pacing (1984)

Safe and reliable DDD pacemakers with multiple programming capabilities have now been developed. Certain programmable parameters are basic, including mode, voltage (or current) output, pulse width, sensitivity and refractory periods in each chamber. Upper rate response as well as low rate settings and A-V delays are equally important. In certain models, the ability to program the blanking period has proven quite useful. The interrelationship between all these functions will assure the smooth overall performance of these sophisticated devices.
