The cutting performance of Al2O3 and Si3N4 ceramic cutting tools in the milling plywood (2017)

This research focuses on the cutting performance of Al2O3 and Si3N4 ceramic cutting tools in up-milling plywood, the results of which are as follows. First, whether the tool material is Al2O3 or Si3N4 ceramic, the cutting forces at low-speed cutting were less than those at high-speed cutting, and the machining quality at low-speed cutting was greater than that at high-speed cutting. Then, whether at low- or high-speed cutting, the cutting forces of Al2O3 cutting tools were higher than those of Si3N4 cutting tools, and the machining quality of plywood milled by Al2O3 ceramic cutting tools was poorer than that milled by Si3N4 ceramic cutting tools. Finally, Si3N4 ceramic cutting tools were more suitable to machine the wooden productions with much glue content than Al2O3 ceramic cutting tools for the better machined quality.
Conserved expression of the Arabidopsis ACT1 and ACT 3 actin subclass in organ primordia and mature pollen. (1996)

We have proposed that ancient and divergent classes of plant actin genes have been preserved throughout vascular plant evolution, because they have distinct patterns of gene regulation. The hypothesis was explored for ACT1 and ACT3, which represent one of the six ancient subclasses in the Arabidopsis actin gene family. Comparison of ACT1 and ACT3 cDNA and genomic sequences revealed highly divergent flaking and intron sequences, whereas they encoded nearly identical proteins. Quantification of their level of divergence suggests that they have not shared a common ancestor for 30 to 60 million years. Gene-specific RNA gel blot hybridization and reverse transcriptase-polymerase chain reaction analyses demonstrated that the distribution of ACT1 and ACT3 mRNAs was very similar: both preferentially accumulated at high levels in mature pollen and at very low levels in the other major organs. The 5' flanking regions of both genes, including the promoter, leader exon and intron, and the first 19 condons, were fused to the beta-glucuronidase (GUS) reporter gene. The expression of these reporter fusions was examined in a large number of transgenic Arabidopsis plants. Histochemical assays demonstrated that both ACT1-GUS and ACT3-GUS constructs were expressed preferentially in pollen, pollen tubes, and in all organ primordia, including those in roots shoots, and the inflorescence. Comparison of the 5' flanking regions of ACT1 and ACT3 revealed a number of short conserved sequences, which may direct their common transcriptional and post-transcriptional regulation. The expression patterns observed were distinct from those of any other other Arabidopsis actin subclass. The conservation of their expression pattern and amino acid sequences suggests that this actin subclass plays a distinct and required role in the plant cytoskeleton.
Quantum leap cluster upgrade (2009)

This paper describes upgrading a running high availability cluster while applications are still running. The whole software stack can be upgraded including operating system, cluster software, volume manager software, application software etc with almost zero downtime. This is done by splitting the cluster in two partitions and upgrading one at a time. This method is different from other split mode upgrade technology by providing the ability to complete all software initialization on the partition running the new software while the older partition hosts service. We call this method Quantum Leap because the cluster leaps from one version of the software to the other.
Potentiation of adrenergic venomotor responses by angiotensin, prostaglandin F 2 and cocaine. (1971)

The influence of infusion of angiotensin, prostaglandin F2a, and cocaine on venoconstrictor responses to sympathetic nerve stimulation and norepinephrine was evaluated in the constant flow pump-perfused saphenous vein preparation of the dog. Infusion of angiotensin, 02 µ/min, increased mean arterial pressure but had no effect on saphenous vein perfusion pressure. Venoconstrictor responses to sympathetic nerve stimulation were enhanced, whereas responses to norepinephrine were not altered. Cocaine, 2 µg/min, and prostaglandin F2a 1 µg/min, had no effect on arterial pressure or saphenous vein perfusion pressure but markedly enhanced responses of the saphenous vein to both sympathetic nerve stimulation and injected norepinephrine. These studies indicate that angiotensin and prostaglandin F2a potentiate the response of the saphenous vein to sympathetic nerve stimulation by a different mechanism and suggest that both substances possess the capacity to act as modulators of adrenergic neurotransmission in venous smooth muscle.
Highly Selective Adsorption of C2/C1 Mixtures and Solvent-Dependent Thermochromic Properties in Metal–Organic Frameworks Containing Infinite Copper-Halogen Chains (2017)

Separation of light hydrocarbon mixtures is a very important but challenging industrial separation task. Here, we have synthesized two isostructural cationic metal–organic frameworks {[(Cu(Btz)X]·X·6H2O·0.25DMSO} (FJU-53, Btz = 1,4′-Bis(4H-1,2,4-triazol-4-yl)benzene, X = Cl or Br, DMSO = dimethyl sulfoxide) containing infinite copper-halogen chains and first demonstrated that the adsorption selectivity toward C2/C1 mixtures in the charged MOFs can be improved by tuning counter-anions. FJU-53 exhibits the highest selectivity for C2H2/CH4 separation at 296 K and 1 atm, and exceptional chemical stability in aqueous solutions with pH ranging from 1 to 13. In addition, FJU-53 also shows the attractive solvent- and halogen-dependent thermochromic behaviors. Its thermochromic mechanism is attributed to the thermally induced vibration of the infinite [(CuX)n]n+ chains, remarkably different from that for the traditional copper(II) halide materials, the thermochromism for which comes from the coordination geometry transformation or Jahn–Teller distortion.
Improved DNA Algorithm for Factoring Integers Based on Pollard p-1 Method (2008)

How to factor big integers effectively is a difficult problem in mathematics. The security of the RSA public-key cryptosystem is based on the difficulty of factoring the product of two large prime numbers. Comparing with conventional electronic computers, the main features of DNA computer are massively parallel computing ability and potential enormous data storage capacity. So it proposes an improved DNA algorithm for factoring integers based on biomolecular technology here. The key of the algorithm is that the pollard p-1 method is used. The problem is solved by tube operation that performs addition, subtraction, multiplication and division to accomplish the square_and_multiply algorithm and the Euclidean algorithm to get the greatest common divisor, and then get the result. On the basis of the experiment method of biomolecular, it can be found the algorithm is an effective one.
Elementarprozesse bei der Herstellung und Stabilisierung von Emulsionen (1983)

Abstract Elementary processes in the production and stabilization of emulsions. When developing new emulsifying agents with a specially low environmental impact, when using emulsifying agents in various branches of industry, and when breaking down emulsions (a very frequent requirement), an understanding of the elementary processes which take place is of great help. The paper provides a comprehensive account of the various elementary processes involved in the production and stabilization of emulsions otherwise scattered throughout the literature. The interplay of the individual elementary processes shows how emulsifying agents and stabilizers differ in their modes of operation. In discussing the structures which occur in aqueous tenside systems, it is pointed out that the swelling of micelles is an elementary process responsible for solubilization and cream formation.
Unconventional Lanthanoid Complexes Supported by Retro-Claisen Condensation Products of β-Triketonates (2018)

β-Triketonates have been recently used as chelating ligands for lanthanoid ions presenting unique structures varying from assemblies to polymers. Despite their novel complexation behaviour little is known about the stability of these molecules. Indeed, two examples of possible in situretro-Claisen condensation reactions have been reported previously. To better understand this possible decomposition pathway, four new β-triketones were synthesised. Complexation reactions were performed for each of these molecules using different alkaline bases in alcoholic media, aiming to isolate the potentially varying ligands present in solution. The X-ray diffraction studies revealed the formation of structures where one, two, or three of the molecules involved in the retro-Claisen condensation reaction were linked to the lanthanoid centres.
Estimated Seepage Losses from Established Swine Waste Lagoons in the Lower Coastal Plain of North Carolina (1995)

Eleven well-established, swine waste lagoon systems in the lower coastal plain of North Carolina were examined for evidence of seepage losses to the surficial aquifer. The sites were selected to represent three major soil systems in the areas of North Carolina with the highest swine populations. Elevated ammonium concentration was the strongest indicator of seepage.

Submicrometre-scale polyaniline colloidal spheres: photopolymerization preparation using fluorescent carbon nitride dots as a photocatalyst (2011)

The present communication reports on a novel synthesis of submicrometre-scale polyaniline colloidal spheres (PANICSs) using fluorescent carbon nitride dots (CNDs) as a photocatalyst for the first time. The subsequent treatment of such colloidal spheres with an aqueous AgNO3 solution produces Ag nanoparticles (AgNPs) decorated PANICSs (AgNPs–PANICSs) composites. Such composites exhibit remarkable catalytic performance toward catalytic reduction of 4-nitrophenol and electrochemical reduction of H2O2.
Facile synthesis and shape evolution of highly symmetric 26-facet polyhedral microcrystals of Cu2O (2009)

A novel type of high symmetric 26-facet polyhedral microcrystals of Cu2O with well-developed {100}, {110}, {111} crystallographic faces are successfully synthesized in a properly selected reaction medium. These polyhedra exhibit a core-shell structure. An aqueous solution containing CuCl2·2H2O, sodium citrate (C6H5Na3O7·2H2O) complexing agent, glucose reductant, sodium dodecyl sulfate (SDS) surfactant, NaOH, and ethylene glycol (EG) constitutes the functional medium. By altering the EG to the water volume ratio, polyhedral, quasi-cubic, octahedral microcrystals are obtained directly. SDS, EG and C6H5Na3O7·2H2O have been confirmed to be the necessary additives to the development of different crystallographic planes. A possible growth mechanism involving aggregation of seed particles, oriented attachment, ripening process and surface reconstruction is proposed on the grounds of time-dependent experiments. The photocatalytic properties of the polyhedral microcrystals are also investigated.
Antireflection Structures on Fresnel Lenses Fabricated by Induced Coupled Plasma Etching for Improving CPV Systems (2013)

Concentrator Photovoltaic (CPV) systems are a potential candidate to achieve low cost solar energy [1]. In these systems the efficiency of the solar cell increases with concentration and the amount of semiconductor material required is lower. CPV systems use Fresnel lenses to focus the light into homogenizers, which provide uniform illumination to the subjacent solar cell and does other optical corrections. A disadvantage of these optical elements is that they create three optical interfaces that reflect the incident light and together account for about 12% of losses. To achieve higher efficiency in CPV systems, these losses need to be addressed. In this paper we report on the EQE enhancement of a Quantum-Dot Solar Cell (QDSC) placed below PMMA substrates with antireflection structures fabricated by Inducted Coupled Plasma etching (ICP). These structures were also applied on the front and back sides of the latest generation Fresnel lenses [2]. Transmittance improvement was measured on the textured Fresnel lenses. Finally, field tests were carried out and enhancements of Jsc and efficiency were demonstrated.
Mechanism-Based Competitive Inhibitors of Glyoxalase I:  Intracellular Delivery, in Vitro Antitumor Activities, and Stabilities in Human Serum and Mouse Serum (1999)

S-(N-Aryl-N-hydroxycarbamoyl)glutathione derivatives (GSC(O)N(OH)C6H4X, where GS = glutathionyl and X = H (1), Cl (2), Br (3)) have been proposed as possible anticancer agents, because of their ability to strongly inhibit the methylglyoxal-detoxifying enzyme glyoxalase I. In order to test this hypothesis, the in vitro antitumor activities of these compounds and their [glycyl,glutamyl] diethyl ester prodrug forms (1(Et)2-3(Et)2) have been examined. All three diethyl esters inhibit the growth of L1210 murine leukemia and B16 melanotic melanoma in culture, with GI50 values in the micromolar concentration range. Cell permeability studies with L1210 cells indicate that growth inhibition is associated with rapid diffusion of the diethyl esters into the cells, followed by enzymatic hydrolysis of the ethyl ester functions to give the inhibitory diacids. In contrast, the corresponding diacids neither readily diffuse into nor significantly inhibit the growth of these cells. Consistent with the hypothesis that cell growth inhibition is due to competitive inhibition of glyoxalase I, preincubation of L1210 cells with 2(Et)2 increases the sensitivity of these cells to the inhibitory effects of exogenous methylglyoxal. Compound 2(Et)2 is much less toxic to nonproliferating murine splenic lymphocytes, possibly reflecting reduced sensitivity to methylglyoxal and/or reduced chemical stability of the diacid inside these cells. Finally, a plasma esterase-deficient murine model has been identified that should allow in vivo testing of the diethyl esters.
Miniaturized MR-compatible ultrasound system for real-time monitoring of acoustic effects in mice using high-resolution MRI (2023)

Visualization of focused ultrasound in high spatial and temporal resolution is crucial for accurately and precisely targeting brain regions noninvasively. Magnetic resonance imaging (MRI) is the most widely used noninvasive tool for whole-brain imaging. However, focused ultrasound studies employing high-resolution (> 9.4 T) MRI in small animals are limited by the small size of the radiofrequency (RF) volume coil and the noise sensitivity of the image to external systems such as bulky ultrasound transducers. This technical note reports a miniaturized ultrasound transducer system packaged directly above a mouse brain for monitoring ultrasound-induced effects using high-resolution 9.4 T MRI. Our miniaturized system integrates MR-compatible materials with electromagnetic (EM) noise reduction techniques to demonstrate echo-planar imaging (EPI) signal changes in the mouse brain at various ultrasound acoustic intensities. The proposed ultrasound-MRI system will enable extensive research in the expanding field of ultrasound therapeutics.
Field tests of cone penetrometer-based, DNAPL characterization methods (2020)

The challenge of dense nonaqueous phase liquid (DNAPL) characterization in the subsurface has been successfully met using a toolbox approach employing several complementary and corroborating technologies grounded in a robust baseline soil sampling method. Some of the best DNAPL characterization tools have been those incorporated with the cone penetrometer test (CPT) to take advantage of its rapid, minimally invasive, and cost-effective access capabilities and its high vertical resolution. Because DNAPL fate is strongly dependent on the often subtle, physical changes in geology and rarely accumulates in large volumes, high resolution techniques are critical for successful detection.
Incorruptible System Self-Cleansing for Intrusion Tolerance (2006)

Despite the increased focus on security, critical information systems remain vulnerable to cyber attacks. The problem stems in large part from the constant innovation and evolution of attack techniques. The trend leads importance to the concept of intrusion tolerance a critical system must fend off or at least limit the damage caused by unknown and/or undetected attacks. In prior work, we developed a self-cleansing intrusion tolerance (SCIT) architecture that achieves the above goal by constantly cleansing the servers and rotating the rule of individual servers. In this paper, we show that, with simple hardware enhancements strategically placed in a SCIT system, incorruptible intrusion containment can be realized. We then present an incorruptible SCIT design for use by one of the most critical infrastructures of the Internet, the domain name services. It is our belief that incorruptible intrusion containment as presented here constitutes a new, effective layer of system defense for critical information system
Papillary carcinoma of the thyroid in Japan: subclassification of common type and identification of low risk group (2004)

Cytological features alone cannot predict patient outcome in PTC. This study indicates for the first time that loss of cellular polarity and the tumour growth pattern are useful parameters for identifying the so called low risk group in common type PTC and in predicting patient outcome in terms of tumour recurrence and cancer related death.
High‐Fat and High‐Sucrose Diets Impair Time‐of‐Day Differences in Spatial Working Memory of Male Mice (2020)

Taken together, these results suggest that both HFD and HSD induce a loss of day/night performance in spatial working memory and synaptic plasticity as well as trigger a cascade of changes that include disruption to the hippocampal molecular clock.
Fine scale inhomogeneity of wind‐wave energy input, skewness, and asymmetry (2005)

Analysis of measured sea and lake wind wave data reveals large variability of the wind energy input, as well as the waves skewness and asymmetry. The spatial and temporal third moments alternate in sign over a few wave periods and over a few wavelengths, respectively. Simulation through a 2D Wave Boundary Layer model in which the air flow is modeled by 2nd order Reynolds equations (Chalikov, 1998) conforms to these findings and exposes a rich structure. We found clear correlation of the variations of the skewness and the asymmetry with the wind input.
Surface-Initiated Ring-Opening Polymerization:  A Versatile Method for Nanoparticle Ordering (2002)

The coordination−insertion ring-opening polymerization of ε-caprolactone was initiated from amine or hydroxyl groups spread over the surface of silica (ca. 30 nm) or cadmium sulfide (ca. 1.5 nm) nanoparticles, respectively. The initiation selectively occurred from the surface functional groups after activation into aluminum alkoxides species. The covalent grafting of the polyester chains was confirmed by the solubilization of the nanoparticles in organic solvents, e.g., CHCl3 and THF for silica nanoparticles and toluene for CdS nanoparticles, at least when the surface-grafted PCL chains were long enough. In the case of silica nanoparticles, the linear dependence of the PCL molar mass as determined by 1H NMR analysis on the initial monomer-to-amine ratio confirmed the controlled character of the polymerization. Transmission electron microscopy of thin films of PCL-grafted CdS revealed an homogeneous dispersion of the semiconducting nanoparticles throughout the polyester matrix.
Human gastric lipase. A kinetic study with dicaprin monolayers (1987)

The effects of several proteins on the hydrolysis at pH 3.0 of didecanoylglycerol monolayers by human gastric lipase were investigated. Among the six proteins tested (bovine serum albumin, myoglobin, a protein inhibiting lipase isolated from soya bean, melittin, beta-lactoglobulin and ovalbumin), only the first three proteins were found to inhibit lipase activity. The inhibition capacity of the proteins was not related to the decrease in interfacial tension or to their isoelectric points. However, inhibition of human gastric lipase by proteins may be correlated with the penetration power of the protein into the lipid interface. It is hypothesized that this lipase has a higher penetration power than that of pancreatic lipase, even though the former enzyme is more susceptible to interfacial denaturation.
Deletion or substitution of the aphthovirus 3′ NCR abrogates infectivity and virus replication (2001)

The 3' noncoding region (NCR) of the genomic picornaviral RNA is believed to contain major cis-acting signals required for negative-strand RNA synthesis. The 3' NCR of foot-and-mouth disease virus (FMDV) was studied in the context of a full-length infectious clone in which the genetic element was deleted or exchanged for the equivalent region of a distantly related swine picornavirus, swine vesicular disease virus (SVDV). Deletion of the 3' NCR, while maintaining the intact poly(A) tail as well as its replacement for the SVDV counterpart, abrogated virus replication in susceptible cells as determined by infectivity and Northern blot assays. Nevertheless, the presence of the SVDV sequence allowed the synthesis of low amounts of chimeric viral RNA at extended times post-transfection as compared to RNAs harbouring the 3' NCR deletion. The failure to recover viable viruses or revertants after several passages on susceptible cells suggests that the presence of specific sequences contained within the FMDV 3' NCR is essential to complete a full replication cycle and that FMDV and SVDV 3' NCRs are not functionally interchangeable.
Trajectory Planning for Spray Painting Robot Based on Point Cloud Slicing Technique (2020)

In this paper, aiming at the problem of poor quality and low spraying efficiency of irregular for complex freeform surfaces, a new spray painting robot trajectory planning method based on point cloud slicing technology is proposed. Firstly, the point cloud data of the workpiece to be sprayed is obtained by laser scanning. The point cloud data is processed to obtain the point cloud model of the sprayed workpiece. Then the section polysemy line is obtained after slice acquisition and section data processing of the point cloud model. The section polysemy line is sampled on average, and the normal vector of all sampling points is estimated. Finally, interpolation algorithm is used to connect the data points to obtain the space trajectory of spraying robot. In addition, the droplet trajectory model for electrostatic spray painting is established. The experimental results show that the method fully meets the requirements of coating thickness and improves the spraying efficiency and uniformity of coating.
