<i>Escherichia coli</i> Expressed Herpes simplex Virus gG1 and gG2 Proteins in ELISA and Immunoblotting Assays (1995)

The type 1 and type 2 glycoprotein G (gG1 and gG2) of herpes simplex virus (HSV) were expressed in Escherichia coli as fusion proteins with the maltose binding protein (MBP) using the pMAL-c2 expression vector. The MBP-gG1 fusion protein contains all but the four amino acids from the amino-terminus of gG1, whereas the MBP-gG2 fusion protein was missing the first 30 amino acids that comprise the signal peptide of the protein. The diagnostic value of these antigens was examined by two methods: (1) immunoblot assay based on MBP-gG1 and MBP-gG2 fusion proteins present in crude E. coli cell extracts and (2) enzyme-linked immunosorbent assay (ELISA) of immunoaffinity-purified recombinant MBP-gG1 and MBP-gG2 fusion proteins. Of 28 serum samples known to have antibody to HSV-1 (10 specimens positive for HSV-1 alone and 18 specimens positive for mixed antibody to HSV-1/HSV-2), 27 were reactive to the MBP-gG1 recombinant protein both in ELISA and in immunoblotting. In addition, of 20 serum samples known to have antibody to HSV-2 (2 specimens positive for HSV-2 alone and 18 samples positive for mixed antibody to HSV-1/HSV-2), 15 were found to be reactive to the MBP-gG2 recombinant protein by ELISA and 16 by immunoblotting. None of the 13 HSV-antibody-negative serum samples showed reactivity to the MBP-gG1 or MBP-gG2 antigens by either assay. Moreover, none of the serum samples known to have antibody to HSV-1 alone showed reactivity to the MBP-gG2 recombinant antigen. This study verified the potential application of the E. coli-expressed recombinant gG1 and gG2 proteins as diagnostic antigens and demonstrated the MBP fusion system to be a simple and effective method of producing adequate amounts of low-cost, easily purified gG antigens.
Occurrence and Distribution of Microcystins in Lake Taihu, China (2013)

The occurrence and distribution of microcystins were investigated in Lake Taihu, the third largest lake in China. An extensive survey, larger and broader in scale than previous studies, was conducted in summer 2010. The highest microcystin concentration was found at southern part of Taihu, which was newly included in this survey. In northern coastal areas, total cellular concentrations of 20 to 44 μg/L were observed. In northern offshore waters, levels were up to 4.8 μg/L. Microcystin occurrence was highly correlated with chemical oxygen demand, turbidity, and chlorophyll-a. Extracellular/total cellular microcystin (E/T) ratios were calculated and compared to other water quality parameters. A higher correlation was found using E/T ratios than original microcystin values. These results show that algal blooms are having a severe impact on Lake Taihu, and further and extensive monitoring and research are required to suppress blooms effectively.
Recommended isolated-line profile for representing high-resolution spectroscopic transitions (IUPAC Technical Report) (2014)

Abstract The report of an IUPAC Task Group, formed in 2011 on “Intensities and line shapes in high-resolution spectra of water isotopologues from experiment and theory” (Project No. 2011-022-2-100), on line profiles of isolated high-resolution rotational-vibrational transitions perturbed by neutral gas-phase molecules is presented. The well-documented inadequacies of the Voigt profile (VP), used almost universally by databases and radiative-transfer codes, to represent pressure effects and Doppler broadening in isolated vibrational-rotational and pure rotational transitions of the water molecule have resulted in the development of a variety of alternative line-profile models. These models capture more of the physics of the influence of pressure on line shapes but, in general, at the price of greater complexity. The Task Group recommends that the partially Correlated quadratic-Speed-Dependent Hard-Collision profile (pCqSD-HCP) should be adopted as the appropriate model for high-resolution spectroscopy. For simplicity this should be called the Hartmann–Tran profile (HTP). The HTP is sophisticated enough to capture the various collisional contributions to the isolated line shape, can be computed in a straightforward and rapid manner, and reduces to simpler profiles, including the Voigt profile, under certain simplifying assumptions.
Increased Serum Neopterin Concentrations in Patients with Alzheimer’s Disease (1999)

We measured serum neopterin concentrations in 24 patients with Alzheimer's disease (8 males, 16 females; age: 73.1+/-6.2 years; free of any infectious process) and fourteen controls of similar age (4 males, 10 females; age: 69.7+/-8.8 years). Compared to controls, significantly higher concentrations of neopterin (p< 0.01) were found in patients with Alzheimer's disease. Among patients, concentrations of neopterin were higher in those with lower mini-mental-state (p < 0.05), and an inverse correlation existed between mini-mental-state and neopterin concentrations. No such association existed with the duration of the disease. There were also significant correlations between neopterin and serum concentrations of immune activation markers such as soluble tumor necrosis factor (TNF) receptor and soluble interleukin-2 receptor (all p<0.01). Thus, increased concentrations of neopterin in serum of patients with Alzheimer's disease correlate with the severity of dementia. The data imply a chronic state of peripheral immune activation in Alzheimer's disease.
CSCL chats analysis using R package (2014)

This paper pCSCL chats analysisresents an approach to text analysis using time series and text mining, in order to extract knowledge from texts in order to analyze the types of texts that are closely related to the time factor, texts whose content can be represented on a temporal axis, such as logs chats. These techniques applied to the document type chat for determining correlations between words that occur most frequently in dialogs, and due to high frequency of occurrence are topics of discussion in the chat, and determine correlations between intervention participants in the dialogue. They can be represented using time series model, the coordinate time is the time of writing reply, and the value at that point is to replicate itself. Based on this representation, can be easily calculated correlations between rhythmic interventions with high occurrence. Research use R package that provides facilities for statistical processing.

Signaling Status: The Impact of Relative Income on Household Consumption and Financial Decisions (2014)

This paper investigates the importance of status in household consumption and financial decisions using household data from the Survey of Consumer Finances (SCF) linked to neighborhood data in the American Community Survey (ACS). We find evidence that a household&amp;amp;amp;#x27;s income rank—its position in the income distribution relative to its close neighbors—is positively associated with its expenditures on high status cars, its level of indebtedness, as well as the riskiness of the household&amp;amp;amp;#x27;s portfolio. More aggregate county-level evidence based on a dataset of every new car sold in each county in the United States since 2002 also suggests that the signaling motive might be important. These results indicate that greater income heterogeneity might have large consequences for household consumption and portfolio decisions.
A Unique and Highly Efficient Method for Catalytic Olefin Aziridination (2002)

A facile, high yielding, and stereospecific method for olefin aziridination is described. This process capitalizes on the unique reactivity of sulfamate esters in combination with 1-2 mol % Rh2(tfacam)4 and PhI(OAc)2 as the terminal oxidant to promote N-atom transfer reactions. A range of structurally and electronically disparate alkenes are found to react under conditions that employ substrate as the limiting reagent and only a slight excess of H2NSO3CH2CCl3 as the nitrogen source. The product alkoxysulfonyl aziridines are useful intermediates that react smoothly with nucleophiles to generate 1,2-amine derivatives. Following aziridine ring-opening, the N-trichloroethoxysulfonyl group can be removed under mild reductive conditions (Zn(Cu)/AcOH-MeOH) to give the corresponding 1 degrees amine. The efficient and convenient performance of this chemistry should establish it as a useful tool for synthesis.
Randomized clinical trial of antithymocyte globulin in cadaver renal allograft recipients: importance of T cell monitoring. (1976)

Despite incontrovertable evidence demonstrating the unique immunosuppressive capabilities of antihymocyte globulin (ATG) in animals, its value in clinical transplantation has remained inconclusive. A multicenter, prospective study was undertaken in an attempt to determine this value. Cadaver renal allograft recipients were randomized into two treatment groups: prednisone and azathioprine only, or prednisone, azathioprine, and ATG. Four to 36 month follow-up of our first 50 recipients, supported by results in over 200 patients from other centers, permits the following observations. (1) Allograft survival can be improved by nearly 20 percent in recipients treated with active ATG preparations. (2) Presently available assays performed in vitro and on subhuman primate allograft survival, though capable of excluding inactive preparations, cannot quantitate precisely the immunosuppressive capacity of active batches of ATG. (3) Monitoring circulating T cell levels in patients receiving ATG appears to offer the best means of defining immunosuppressive potency and the variation in response to the agent among identically treated individuals. It is concluded that ATG therapy can be beneficial in renal transplantation; but monitoring of recipients' T cell level is desirable during therapy to determine the dosage required. Furthermore, the optimal immunosuppressive protocol can be approximated by modifying the regimen according to individual variations in response, thus limiting the infectious complications of excessive immunosuppression.
Effects of Membrane Thickness on the Pyroelectric Properties of LiTaO<sub>3</sub> Thin Film IR Detectors (2005)

High-performance pyroelectric infrared (IR) detectors have been fabricated using lithium tantalite (LiTaO 3 ) thin films deposited on Pt(111)/Ti/SiO 2 /Si(100) substrates by the diol-based sol–gel method. The thermal isolation of detecting elements was achieved by anisotropic wet etching of the back of the silicon substrate. In order to reduce the thermal mass and thermal time constant of the detector, the sensing element was fabricated on a thin membrane. The effects of membrane thickness on the response of pyroelectric IR detectors were studied by changing the membrane thickness (20–350 µm). As the membrane thickness decreased, the voltage responsivity ( R v ) increased from 4300 up to 8398 V/W, and the specific detectivity ( D * ) also increased from 1.2×10 8 to 2.7×10 8 cm·Hz 1/2 /W. Experimental results reveal that the thermally isolated detectors with membrane thickness of 20 µm exhibit excellent sensitivity.
Smart Materials, Precision Sensors/Actuators, Smart Structures, and Structronic Systems (2004)

Many electroactive functional materials have been used in small- and microscale transducers and precision mechatronic control systems for years. It was not until the mid-1980s that scientists started integrating electroactive materials with large-scale structures as in situ sensors and/or actuators, thus introducing the concept of smart materials, smart structures, and structronic systems. This paper provides an overview of present smart materials and their sensor/actuator/structure applications. Fundamental multifield optomagnetopiezoelectric-thermoelastic behaviors and novel transducer technologies applied to complex multifield problems involving elastic, electric, temperature, magnetic, light, and other interactions are emphasized. Material histories, characteristics, material varieties, limitations, sensor/actuator/structure applications, and so forth of piezoelectrics, shape-memory materials, electro- and magnetostrictive materials, electro- and magnetorheological fluids, polyelectrolyte gels, superconductors, pyroelectrics, photostrictive materials, photoferroelectrics, magneto-optical materials, and so forth are thoroughly reviewed.
Algorithms for Mining Association Rules for Binary Segmentations of Huge Categorical Databases (1998)

We consider the problem of finding association rules that make nearly optimal binary segmen-tations of huge categorical databases. The op-timality of segmentation is defined by an ob-jective function suitable for the user’s objec-tive. An objective function is usually defined in terms of the distribution of a given target attribute. Our goal is to find association rules that split databases into two subsets, optimiz-ing the value of an objective function. The problem is intractable for general ob-jective functions, because letting N be the number of records of a given database, there are 2N possible binary segmentations, and we may have to exhaustively examine all of them. However, when the objective function is convex, there are feasible algorithms for finding nearly optimal binary segmentations, and we prove that typical criteria, such as “entropy (mutual information), ” “x2 (correla-tion), ” and “gini index (mean squared error),” are actually convex. We propose practical algorithms that use computational geometry techniques to handle

Synergistic fluorescence quenching of quinolone antibiotics by palladium(<scp>ii</scp>) and sodium dodecyl benzene sulfonate and the analytical application (2014)

Ternary complexes composed of Pd(<sc>ii</sc>)–PEF–SDBS with 1 : 2 : 2 ratio resulted in a higher fluorescence quenching efficiency and enhanced the sensitivity for the determination of Pd(<sc>ii</sc>).
Dispersity and Size of Silica Particles Constructing Thick Films Prepared by Electrophoretic Sol-Gel Deposition (1995)

Thick silica films prepared on a stainless steel sheet by the electrophoretic sol-gel deposition in the presence of sodium dodecyl sulfate (SDS) as a surfactant were found to be an agglomerate of fine silica particles. The size and the dispersity of the silica particles on the sheet were dependent on the concentrations of both tetraethoxysilane (TEOS) and SDS. The particle size increased with an increase in the content of SDS. Monodispersed particles were obtained at relatively low concentrations of TEOS, whereas bimodal particles were deposited at higher concentrations of TEOS.
Current-driven insulator–conductor transition and nonvolatile memory in chromium-doped SrTiO3 single crystals (2001)

Materials showing reversible resistive switching are attractive for today’s semiconductor technology with its wide interest in nonvolatile random-access memories. In doped SrTiO3 single crystals, we found a dc-current-induced reversible insulator–conductor transition with resistance changes of up to five orders of magnitude. This conducting state allows extremely reproducible switching between different impedance states by current pulses with a performance required for nonvolatile memories. The results indicate a type of charge-induced bulk electronic change as a prerequisite for the memory effect, scaling down to nanometer-range electrode sizes in thin films.
Selectional Asymmetries between CP and DP Suggest that the DP Hypothesis is Wrong (2009)

Nearly every researcher in generative grammar now adopts the position that the head of the noun phrase is not N, but is some higher functional projection, entirely parallel to clauses, where higher functional projections dominate the lexical verb. One version of this involves the notion of an extended projection (Grimshaw 1991, van Riemsdijk 1998), where clauses are in some sense extended projections of verbs, and DPs are in some sense extended projections of nouns. However, all facts regarding complement selection and the determination of form indicate that the head of the clause is not the verb; C is (and the head of its complement is not the verb, but some other functional head; and so on down). But the same types of facts indicate that the head of a nominal phrase is not a functional projection like D; it is N. This asymmetry calls into question the correctness of the DP hypothesis. Verbs that select for clausal complements commonly select for C, or other things that are usually re-garded as residing high in the functional domain of the clause. They select for questions versus declaratives (*Sue thinks what time it is); finite versus nonfinite (*Bertrand wants that the world is round); subjunctive versus indicative (Sue asked that the answer be/*is two). In other languages they may select V2 clauses (German) or illocutionary force (exhortative in Korean, imperative in Japanese). No verb ever selects for the verb in the embedded CP, or for modals, auxiliaries, or negation, which can generally appear in any com-
The spectrophotometric determination of tyrosine and tryptophan in proteins (1946)

I8olation of veratric acid. Some 800 oothecae of Blatta orientali8 were crushed in dilute aqueous potassium cyanide (c. 250 ml.) containing some sulphur. dioxide. After 3 hr. the mixture was filtered with the aid of 'Hyflo supercel'. The filtrate was weakly acid-to litmus. The residue was extracted further by allowing to stand for 2 hr. with water (300 ml.) which had been made just acid to Congo red with sulphuric, acid, and the procedure repeated until the extracts no longer gave a green colour with ferHic chloride. The com- bined filtrate and extracts were concentrated in vacuo under nitrogen to small bulk (c. 300 ml.), the concentrate filtered from a trace of solid material and extracted continuously with peroxide-free ether (700 ml.). The ethereal extract which con- tained all the material giving a coloration with ferric chloride was concentrated to one-third bulk and treated with ethereal diazomethane (from 10 g. nitroso-N-methylurea). After 2 days the ether was evaporated and the residue refluxed for 2 hr. with methanolic potassium hydroxide' (2 %).
Good Bonding for Low-Energy HT-CTMP by press drying (2004)

La consommation d'energie du procede PCTM-HT (PCTM haute temperature) est tres faible, mais les fibres produites possedent une faible capacite de cohesion en raison de la lignine adherant a la surface de fibres. Le pressage-sechage pourrait se reveler une solution possible permettant d'ameliorer la cohesion. La temperature elevee lors du pressage-sechage favorise le ramollissement des polymeres du bois sur la surface de la feuille, ce qui permet d'ameliorer la cohesion. Des etudes en laboratoire ont demontre que le pressage-sechage ameliore substantiellement la cohesion des fibres de PCTM-HT.
