Nuclear Pore Complex Is Able to Transport Macromolecules with Diameters of ∼39 nm (2002)

Bidirectional transport of macromolecules between the nucleus and the cytoplasm occurs through the nuclear pore complexes (NPCs) by a signal-mediated mechanism that is directed by targeting signals (NLSs) residing on the transported molecules or "cargoes." Nuclear transport starts after interaction of the targeting signal with soluble cellular receptors. After the formation of the cargo-receptor complex in the cytosol, this complex crosses the NPC. Herein, we use gold particles of various sizes coated with cargo-receptor complexes to determine precisely how large macromolecules crossing the NPC by the signal-mediated transport mechanism could be. We found that cargo-receptor-gold complexes with diameter close to 39 nm could be translocated by the NPC. This implies that macromolecules much larger than the assumed functional NPC diameter of 26 nm can be transported into the karyoplasm. The physiological relevance of this finding was supported by the observation that intact nucleocapsids of human hepatitis B virus with diameters of 32 and 36 nm are able to cross the nuclear pore without disassembly.
Syntheses of Anthracenones. 1. Sodium Dithionite Reduction of peri-Substituted Anthracenediones (1996)

The reaction of peri-substituted anthracenediones with sodium dithionite in dimethylformamide and water has been investigated. The system selectively reduces the carbonyl group flanked by the peri substituents of the anthracenediones to give the corresponding 4,5-disubstituted 9(10H)-anthracenones and thus provides a route to anthracenones which are otherwise difficult to obtain. Many functional groups can be tolerated, the reaction is compatible with the presence of peri alkoxy groups and unsaturated side chains of the starting anthracenediones, and the reduction does not go beyond the anthracenone stage. However, the formation of anthracenones depends on the nature of the peri substituents. No products were obtained from the 1,8-dimethyl-substituted anthracenedione and the parent compound with no substituents.
A contour based procedure for face detection and tracking from video (2016)

During the past few years face detection and tracking from video has received maximum importance because of commercial and enforcement application of varied an extreme range. It is also most challenging task in video, where the variation of illuminations, noise, locations of human face and pose can differ from one frame to another. For face detection and tracking from video database is being presented a unique technique in this paper. In this study, primary goal is to recognize location of faces from video. Moreover, finding face motion leads to be a part of face recognition system. Firstly, face edges are detected using Robert edge detector followed by a set of arithmetic operations between an initial frame and the nearest ones. Thereafter, non-desired edges and noise are removed by Gaussian filtering technique. A logical operation is then performed between the previous two output frames and noiseless face contour frame for detecting edges corresponding to face video. Finally, four corner points i.e. top-left, top-right, bottom-left, bottom-right are computed to draw rectangle around the face and detect face contour of each frame. To track human face from video, scalar and vector distance between four corner points of two consecutive frames are calculated. Displacement of corner points means position and location of face changes in the next frame. On Honda/UCSD video database the proposed method has been tested and it has been found through experimental results that it can detect and track from video efficiently human face.

Coma in a 20-Month-Old Child From an Ingestion of a Toy Containing 1,4-Butanediol, A Precursor of γ-Hydroxybutyrate (2009)

Ingestion of plastic toys is common in children and usually does not result in harm. We report a case of coma in a 20-month-old child after an ingestion of a toy containing 1,4-butanediol, an industrial solvent used to manufacture plastics. When ingested, 1,4-butanediol is metabolized to γ-hydroxybutyrate, which can have significant systemic effects including death. Health care providers should suspect the possibility of a toxic component when a presumed nontoxic object causes unusual symptoms.

Capillary flow of amorphous metal for high performance electrode (2013)

Metallic glass (MG) assists electrical contact of screen-printed silver electrodes and leads to comparable electrode performance to that of electroplated electrodes. For high electrode performance, MG needs to be infiltrated into nanometer-scale cavities between Ag particles and reacts with them. Here, we show that the MG in the supercooled state can fill the gap between Ag particles within a remarkably short time due to capillary effect. The flow behavior of the MG is revealed by computational fluid dynamics and density funtional theory simulation. Also, we suggest the formation mechanism of the Ag electrodes and demonstrate the criteria of MG for higher electrode performance. Consequently, when Al85Ni5Y8Co2 MG is added in the Ag electrodes, cell efficiency is enhanced up to 20.30% which is the highest efficiency reported so far for screen-printed interdigitated back contact solar cells. These results show the possibility for the replacement of electroplating process to screen-printing process.
Case study of TV spectrum sensing model based on machine learning techniques (2021)

Spectrum sensing is an essential component in cognitive radios (CR). Machine learning (ML) algorithms are powerful techniques for designing a promising spectrum sensing model. In this work, the supervised ML algorithms, support vector machine (SVM), k-nearest neighbor (kNN), and decision tree (DT) are applied to detect the existence of primary users (PU) over the TV band. Moreover, the Principal Component Analysis (PCA) is incorporated to speed up the learning of the classifiers. Furthermore, the ensemble classification-based approach is employed to enhance the classifier predictivity and performance. Simulation results have shown that the highest performance is achieved by the ensemble classifier. Moreover, simulation results have shown that employing PCA reduces the duration of training while maintaining the performance.
Novel anti-biofouling light-curable fluoride varnish containing 2-methacryloyloxyethyl phosphorylcholine to prevent enamel demineralization (2019)

We evaluated the efficacy of light-curable fluoride varnish (LCFV) that contains 2-methacryloyloxyethyl phosphorylcholine (MPC) in terms of anti-biofouling properties and prevention of tooth enamel demineralization. MPC was mixed with and incorporated into LCFV at 0 (control), 1.5, 3.0, 5.0, 10.0, 20.0, and 40.0 weight percentage (wt%). Addition of high wt% of MPC resulted in increased film thickness and decreased the degree of conversion, indicating loss of the advantageous properties of LCFV. Addition of 1.5, 3, or 5 wt% MPC significantly reduced the amount of bovine serum albumin adsorbed from a solution and proteins adsorbed from brain heart infusion medium compared to the control (P < 0.001). A similar pattern was observed for bacterial adhesion: significantly less Streptococcus mutans cells adhered on the surface of LCFV with 1.5, 3, or 5 wt% MPC (P < 0.001) than on the control, and similar results were obtained for Actinomyces naeslundii and Streptococcus sanguinis adherence to LCFV with 3 wt% MPC. Finally, bacterial adhesion, surface microhardness loss, and the depth of demineralization were substantially lower on bovine tooth enamel surface coated with LCFV containing 3 wt% of MPC than in the control treatment (0 wt% MPC). Therefore, this novel LCFV containing a low concentration of MPC (e.g., 3 wt%) would be effective in anti-biofouling while maintaining the important advantageous features of light-curable fluoride in preventing demineralization.
DEMONSTRATION OF DAIRY MANURE REMEDIATION USING IBR TECHNOLOGY (2002)

This paper is a report of the performance of a new design of an aerobic bioreactor called the induced blanket reactor or IBR. The IBR appears to treat high-solids organic matter (manure) effectively in a relatively short time without plugging. A 28 m 3 (7500 gal.), heated IBR has been in operation at Utah State University’s dairy farm, the Caine Dairy, since the summer of 2000. The bioreactor, an upflow sludge blanket type, features a method to build and maintain a sludge blanket without plugging. Up to 80 % of the VSS were removed from dairy manure in the IBR with less than a 10-day HRT. Biogas was collected and burned to produce hot water. Parameters for the system that were reported include pH, temperature, influent and effluent totals, soluble COD, total and volatile solids, and suspended solids. All these parameters were recorded at different loading rates. Biogas quality with percent of methane content was also reported.

A Comparative Analysis on Image Quality Assessment for Real Time Satellite Images (2016)

Objectives: The objective of this paper is to analyze the different image quality metrics by testing and comparing with different distorted set of satellite images. Methods/Statistical Analysis: In this paper, we propose the methods for analyzing the quality of real time images that are corrupted due to different distortions. The several quality metrics are applied and ultimately the best metrics are derived based on the type of degradation. Different metrics such as metric based on single image and metric based on two images have been tested with different real time satellite images from NASA data sets. Findings: This framework will help to identify the metrics in order to prove the proposed filtering schemes that are applied to the corrupted images. Based on the results, we have concluded the characteristics of different quality metrics and further we successfully identified the quality metric appropriate to various distortions. Application/Improvements: The proposed quality metric analysis is used to estimate the performance of any filtering schemes which are used to enhance the quality of any real time images such as remote sensing field.Keywords: Assessment, Blur, Gaussian, Metrics, Quality, Satellite Images, Salt and Pepper
Synthesis and Properties of Single-Crystal FeSi Nanowires (2006)

We report for the first time the chemical synthesis of free-standing single-crystal nanowires (NWs) of FeSi, the only transition-metal Kondo insulator and the host structure for ferromagnetic semiconductor Fe(x)Co(1-x)Si. Straight and smooth FeSi nanowires are produced on silicon substrates covered with a thin layer of silicon oxide through the decomposition of the single-source organometallic precursor trans-Fe(SiCl3)2(CO)4 in a simple chemical vapor deposition process. Unlike typical vapor-liquid-solid (VLS) NW growth, FeSi NWs form without the addition of metal catalysts, have no catalyst tips, and depend strongly on the surface employed. X-ray spectroscopy verifies the identity and the room-temperature metallic nature of FeSi NWs. Room-temperature electrical transport measurements using NW devices show an average resistivity of 210 micro Omega cm, similar to the value for bulk FeSi. Investigations into the low-temperature physical properties of the first one-dimensional Kondo insulator and the possible new NW growth mechanism are underway. This unique synthetic approach to FeSi NWs will be generally applicable to many other transition-metal silicides.

Periplanone total synthesis via intramolecular pinacol coupling (1994)

We have carried out an enantioselective synthesis of (-)-periplanone C by a route involving titanium-induced, intramolecular pinacol coupling reaction of a 1,10 keto aldehyde as the key step. The coupling occurs with predictable stereochemistry to give a mixture of two diol products in greater than 60% yield.
Virtual Simulation Experiment Design under the Guidance of Emotional Design Theory (2019)

In recent years, virtual simulation experiments have been widely used in education. However, at present, academic research on virtual simulation experiments mostly focuses on key technologies, and there are few emotional studies on virtual experiments. Based on the three-layer model of emotional design theory, this paper puts forward the method strategy of emotional simulation design in virtual simulation experiment, in order to provide some reference value for the design of virtual simulation experiment.
Design of two-stage thermoacoustic Stirling engine coupled with push-pull linear alternator for waste heat recovery. (2015)

Thermoacoustics is suitable technology for recovering waste heat and generating electricity. In this paper, a novel thermoacoustic electricity generator using a push-pull linear alternator is proposed. It is aimed to recover part of the internal combustion engine exhaust waste heat and produce useful electricity. It consists of two half wave length identical stages and a linear alternator connected in between them. The physically identical stages produce identical wave halves with acoustic pressure out of phase. The availability of two points having the same pressure amplitude out of phase provides the opportunity to connect the linear alternator to two points in each stage to run the alternator in a "push and pull" mode. The proposed engine is able to produce more than 138.4W of electricity at thermal-to-electrical efficiency of 25.1% equivalent to a fraction of Carnot efficiency of 45.1% while using helium pressurized at 40 bar.

Clinical assessment of a synthetic biomaterial containing hydroxyapatite and beta tricalcium phosphate in socket preservation (2022)

The alloplastic graft material consisting of Hyrdoxyapatite (HA) and beta-tricalcium phosphate (β-TCP) in the preservation of ridge volume after tooth extraction can maintain the bone for improve the success of dental implant. This case series evaluated the clinical efficacy of a synthetic material containing HA and β-TCP (OsvehOss®) in the alveolar ridge preservation of an extraction socket. A total of twenty healthy patients reported for tooth extraction were enrolled in this study. They received extraction socket preservation using OsvehOss® followed by delayed implant placements. After the surgery, they were evaluated after 24, 48 and 168 hours for several clinical parameters, including pain, sinus tract, infection, color change and other inflammatory variables. Data were assessed by Kolmogorov–Smirnov and t-test analysis. Twenty patients containing 14 women (70%) and 6 men (30%) with a range of 22-58 years (36.65±12.65) completed the three measurements. Despite the greater average age of women than men, the t-test analysis showed no significant difference between the mean age of women and men (P = 0.201). No negative results were found for evaluating clinical parameters; therefore, no analytical statics were performed. Also, there was no statistically significant correlation between gender and infection (p = 0.521). Regarding the limitation of this study, it can be concluded the bio material containing HA and β-TCP (OsvehOss®) can be used for socket preservation before implant placement with no significant clinical complications.
Characterization of diene polymers. I. Infrared and NMR studies: Nonadditive behavior of characteristic infrared bands (1971)

Abstract Extinction coefficients of the characteristic infrared bands due to isomeric structural units were measured for polybutadiene and polyisoprene in CS 2 or CCl 4 solutions and were compared with the isomer composition determined by NMR. The NMR signal assignments were made on the basis of the spectra of deutero derivatives of the polymers. In the case of polyisoprene, linear relations were obtained between the extinction coefficients and the isomer contents determined by NMR for the absorption bands at 1385 cm −1 (characteristic of trans ‐1,4 units), 1376 cm −1 ( cis ‐1,4 units), and 889 cm −1 (3,4 units). However, for the absorption bands at 840 cm −1 (characteristic of cis ‐1,4 and trans ‐1,4 units), isomerized polyisoprenes did not give such a linear relationship. In polybutadiene, the extinction coefficient for the atactic 1,2 units was found to be lower than that of the syndiotactic 1,2 unit. These experimental facts lead to the conclusion that additivity of the extinction coefficients does not always hold for diene polymers. The deviation from the linear relation may be associated with regular sequences of one isomeric conformation in the chain.
Sickness Response Symptoms among Healthy Volunteers after Controlled Exposures to Diesel Exhaust and Psychological Stress (2011)

These results suggest that exposure to DE can cause acute sickness response symptoms and that these symptoms are also associated with increased levels of self-reported chemical intolerance. The results did not confirm our hypothesis that an acute stressor would increase sickness response symptom severity during the exposure.
Cavity ring-down polarimetry (CRDP): theoretical and experimental characterization (2002)

Detailed theoretical analyses are presented for cavity ring-down polarimetry, a recently developed scheme for probing circular birefringence (nonresonant rotatory dispersion) and circular dichroism (resonant differential absorption) with unprecedented sensitivity. Aside from elucidating the nature of time-resolved signals generated by various modes of operation, the influence of instrumental imperfections on polarimetric response is examined. The unique ability of cavity ring-down polarimetry to interrogate nonresonant optical activity in low-pressure chiral vapors is demonstrated by extracting specific rotation parameters at two complementary excitation wavelengths (355 nm and 633 nm) for gaseous samples of α-pinene, β-pinene, and cis-pinane. The resulting isolated-molecule properties are contrasted with those derived from conventional solution-phase experiments and state-of-the-art ab initio calculations.
Reversible Supramolecular Surface Attachment of Enzyme–Polymer Conjugates for the Design of Biocatalytic Filtration Membranes (2015)

To be used successfully in continuous reactor systems, enzymes must either be retained using filtration membranes or immobilized on a solid component of the reactor. Whereas the first approach requires large amounts of energy, the second approach is limited by the low temporal stability of enzymes under operational conditions. To circumvent these major stumbling blocks, we have developed a strategy that enables the reversible supramolecular immobilization of bioactive enzyme-polymer conjugates at the surface of filtration membranes. The polymer is produced through a reversible addition-fragmentation transfer method; it contains multiple adamantyl moieties that are used to bind the resulting conjugate at the surface of the membrane which has surface-immobilized cyclodextrin macrocycles. This supramolecular modification is stable under operational conditions and allows for efficient biocatalysis, and can be reversed by competitive host-guest interactions.

Domain Closure in Adenylate Kinase (1996)

The method of time-resolved dynamic nonradiative excitation energy transfer (ET) was used to analyze the proposed domain closure in adenylate kinase (AK). A highly active mutant of Escherichia coli AK, (C77S, V169W, A55C)-AK, was prepared, in which the solvent- accessible residues valine 169 and alanine 55 were replaced by tryptophan (the donor of excitation energy) and cysteine, respectively. The latter was subsequently labeled with either 5- or 4-acetamidosalicylic acid (the acceptor). From the comparative analysis of AK crystal structures [Schulz, G.E., Müller, C.W., & Diederichs, K. (1990) J. Mol. Biol. 213, 627-630] (apo-AK,AK.AMP complex and AK.AP5A [P1,P5-di(adenosine-5') pentaphosphate] complex), "sequential formation" of the pseudoternary AK.AP5A complex is followed by two- step domain closure. The domain closure reduces interdomain distances in a two-step manner. Specifically, the distance between C alpha-atoms of the residues 169 and 55 (numbers correspond to those of E. coli AK) is decreased from 23.6 A in the apo-enzyme to 16.2 A upon the formation of the AK.AMP complex and to 12.3 A upon the further formation of the pseudoternary AK.AP5A complex. Time-resolved dynamic nonradiative excitation energy transfer was measured for the following ligand forms of the labeled derivative of the mutant enzyme: the apo-enzyme, the enzyme-MgATP complex, the enzyme.AMP complex, and the enzyme.AP5A "ternary" complex. The transfer efficiencies, which were determined in these experiments, were approximately 7.5%, 22%, 33%, and 65%, respectively. Global analyses of the time resolved ET experiments with the same ligand forms yielded intermolecular distance distributions with corresponding means of 31, 23, 19, and 12 A and full widths at half- maximum of 29, 24, 14, and 11 A. The data confirmed the proposed stepwise manner of the domain closure of the enzyme and revealed the presence of multiple conformations of E. coli AK in solution.
