Inhibition mechanisms of baicalin and its phospholipid complex against DHAV-1 replication (2018)

Duck hepatitis A virus type 1 (DHAV-1) is a serious infectious virus of ducklings. Recent study showed baicalin (BA) and baicalin phospholipid complex (BAPC) possessed anti-DHAV-1 effect. However, the antiviral mechanism is not clear. Therefore, the aim of the present work is to study influences and mechanisms of BA and BAPC on DHAV-1. The effects of BA and BAPC on DHAV-1 replication were analyzed by CCK-8 and RT-qPCR methods. And the results showed BA inhibited the replication of DHAV-1, and BAPC was more effective. Then, the influences of BA and BAPC on DHAV-1 protein translation and RNA synthesis were detected by western blot and RT-qPCR. Both BA and BAPC inhibited the protein translation, and BAPC did better. Furthermore, BAPC also inhibited the RNA synthesis. Afterwards, DHAV-1 IRES activity, DHAV-1 3D protein stability, and cellular Hsp70 expression were studied to in-depth understand the inhibition effects of BA and BAPC on DHAV-1 replication. The results indicated BA and BAPC dropped the protein translation via suppressing DHAV-1 IRES activity. Additionally, BAPC dropped the RNA synthesis via reducing the 3D protein stability and inhibiting cellular Hsp70 expression.
CO2 Capture System Using Lithium Silicate for Distributed Power Supply (2013)

Distributed power-supply systems have become more widespread recently. Recent distributed systems, such as fuel cells, offer high energy-use efficiency because they generate heat or hot water and electric power simultaneously. However, to avoid global warming, carbon dioxide (CO2) from the exhaust gas has to be collected and separated, without emitting it to the atmosphere. We are investigating lithium silicate (Li4SiO4) (LS) because it has superior characteristics as a CO2 absorber. Aiming at the construction of a CO2 capture and separation system using LS, we are studying ways to process (capture and separate) the exhaust gas from distributed power-supply systems. We thought that the CO2 capture and separate system we should design must process exhaust gases with 30% CO2 concentration and 35 L/min flow rate and that it must capture and separate more than 50% of the CO2 contained in the exhaust gases. However, as a result of a preliminary estimation, it became clear that the volume of the assumed CO2 capture and separate system would be considerable. Therefore, we built a reduction model experimental setup with three reaction containers with three different aspect ratios. The results regarding container shape suggest that a long container would be advantageous..
Decreased Fibronectin Production Significantly Contributes to Dysregulated Repair of Asthmatic Epithelium (2010)

These data show that the reduced capacity of asthmatic epithelial cells to secrete FN is an important contributor to the dysregulated AEC repair observed in these cells.
Channel cracks in a hermetic coating consisting of organic and inorganic layers (2007)

Flexible electronic devices often require hermetic coatings that can withstand applied strains. This letter calculates the critical strains for various configurations of channel cracks in a coating consisting of organic and inorganic layers. The authors show that the coating can sustain the largest strain when the organic layer is of some intermediate thicknesses.
Synthesis of Thermally Sensitive Water-Soluble Polymethacrylates by Living Anionic Polymerizations of Oligo(ethylene glycol) Methyl Ether Methacrylates (2003)

Anionic polymerizations of 2-methoxyethyl methacrylate (1), 2-(2-methoxyethoxy)ethyl methacrylate (2), and 2-[2-(2-methoxyethoxy)ethoxy]ethyl methacrylate (3) were carried out with 1,1-diphenyl-3-methylpentyllithium/lithium chloride and diphenylmethylpotassium/diethylzinc in THF at −78 °C for 2−4 h. The resulting polymers possessed the predicted molecular weights based on the molar ratios between monomers to initiators and the narrow molecular weight distributions (Mw/Mn < 1.1). The stability of the propagating chain ends of poly(2) and poly(3) was confirmed by the quantitative efficiency in the reversible sequential block copolymerizations between 2 and 3. New block copolymers having well-defined chain structures, poly(2)-block-poly(3), poly(3)-block-poly(2), polystyrene-block-poly(1), polystyrene-block-poly(2), and polystyrene-block-poly(3), were anionically synthesized. Both the solubility and the cloud point of polymers strongly depended on the length of hydrophilic oligo(ethylene glycol) unit. Poly(2) and poly(3) with longer oligo(ethylene glycol) chains were readily soluble in water, whereas poly(1) was insoluble in water. The aqueous solutions of poly(2) and poly(3) showed the reversible cloud points at 26 and 52 °C, respectively.
Nutrition and immunity. (1989)

Nutrition is a critical determinant of immunocompetence and risk of illness. The critical role of nutrition in modulation of immune responses is based on physiological considerations. In humans, isolated vitamin A deficiency seldom occurs, and it is usually associated with protein energy malnutrition. Excessive intake of nutrients and vitamins impairs immune response and may be considered a type of malnutrition. The extent of immunological impairment depends not only on the severity of nutritional deficiency but also on the presence of infection. The immune system is an important link in the chain of host defense mechanisms and protects the host from the microbial invasion. An incompetent immune system is one of the factors that add to the vulnerability of the deficient individual to infection. Most research concerning the role of iron in immunity has been concentrated in the area of cell-mediated immune response, and several approaches have been used to study cell-mediated immunity in iron deficiency.
Human Papillomavirus Genotype Specificity of Hybrid Capture 2 Low-Risk Probe Cocktail (2009)

A genotyping study of 285 Hybrid Capture 2 low-risk probe cocktail-positive specimens showed cross-reactivity with several untargeted human papillomavirus genotypes. Cross-reactivity was often clinically beneficial due to the detection of untargeted low-risk genotypes. A total of 8.4% of positive results, usually weak, were due to cross-reactivity with high-risk genotypes. Establishment of a gray zone is recommended.
MIND: a tiled display visualization system at CATE/FIU (2007)

This paper reports the experience of building a highly efficient system for cluster visualization. This implementation was based on the well known master/slave concept which states that, given a master node, which is a node chosen to interact with the user and able to process the graphical user interface, splits its display into sections and sends it to nodes for their individual rendering. Chromium was used to perform the parallel remote rendering operation. In this paper, the detailed aspects of the Visualization Cluster implementation, called MIND, the hardware and software utilized in the project execution and the foremost issues found during the implementation were discussed. A cluster with 16 nodes was employed, connected with a Gigabit LAN. 15 servers, each driving a 20 LCD, were used as slave nodes and one as Master node. Furthermore, the benchmark test results are presented to relate the network bandwidth and the visualization speed of a given data size. An elite design in this system is the development of a script to automate the creation and/or insertion of data into the display node's configuration files using a XML-schema, in so doing, any Linux machine can become a compute node used for the visualization display system.

Obstacle avoidance for small UAVs using monocular vision (2011)

Purpose The purpose of this paper is to propose that the three‐dimensional information of obstacles should be identified to allow unmanned aerial vehicles (UAVs) to detect and avoid obstacles existing in their flight path. Design/methodology/approach First, the approximate outline of obstacles was detected using multi‐scale‐oriented patches (MOPS). At the same time, the spatial coordinates of feature points that exist in the internal outline of the obstacles were calculated through the scale‐invariant feature transform (SIFT) algorithm. Finally, the results from MOPS and the results from the SIFT algorithm were merged to show the three‐dimensional information of the obstacles. Findings As the method proposed in this paper reconstructs only the approximate outline of obstacles, a quick calculation can be done. Moreover, as the outline information is combined through SIFT feature points, detailed three‐dimensional information pertaining to the obstacles can be obtained. Practical implications The proposed approach can be used efficiently in GPS‐denied environments such as certain indoor environments. Originality/value For the autonomous flight of small UAVs having a payload limit, this paper suggests a means of forming three‐dimensional information about obstacles with images obtained from a monocular camera.
Migration imaging enhancement through optimized alignment of vector image partitions (2014)

Stacking is a very important step in seismic processing to enhance signal-to-noise (S/N) ratio and improve image quality. The traditional stacking method usually treats each input equally and sums them into the final image without distinguishing the individual contribution of each input data set, which cannot robustly suppress coherent noises. We describe a novel, iterative method to clean and enhance the stacked migration image through optimized alignment of vector image partitions (VIPs). To demonstrate the superiority of our algorithm, we present both synthetic and field examples of stacking prestacked reverse time migration (RTM) VIP gathers.
Determination of Lignin Content of<i>Eucalyptus globulus</i>Wood Using FTIR Spectroscopy (1998)

FTIR spectroscopy was used to quantitatively determine lignin in Eucalyptus globulus wood. A total of 40 wood samples from a 9 year old provenance trial was divided into two independent sets for calibration and validation. Lignin contents, as determined by the acetyl bromide method, ranged from 23 % to 34 % o.d. extractive-free wood. Spectra were recorded with the KBr pellet technique and twelve peaks between 1800cm -1 to 800cm -1 used for calibration by linear regression. The best calibration fit (R 2 =0.98) was obtained with the 1505 cm -1 peak from lignin and the 1157 cm -1 peak from polysaccharides as a reference. The standard error of calibration (SEC), and the standard error of prediction (SEP) calculated with the validation set, were very low. A linear regression of FTIR measurements proved strong enough to predict lignin content with a very high coefficient of determination. The accuracy of FTIR techniques allows its use in large scale breeding programmes to assess wood lignin content with considerable less effort and shorter time than using wet-lab methods, once a reliable calibration is performed for the species.

Upconversion emission tuning from green to red in Yb<sup>3+</sup>/Ho<sup>3+</sup>-codoped NaYF<sub>4</sub>nanocrystals by tridoping with Ce<sup>3+</sup>ions (2009)

Upconversion (UC) emission tuning from green to red in monodisperse NaYF(4):Yb(3+)/Ho(3+) nanocrystals was successfully achieved by tridoping with Ce(3+) ions under diode laser excitation of 970 nm. It is proposed that two efficient cross-relaxation processes, 5S2/5F4(Ho) + 2F(5/2)(Ce) --> 5F5(Ho) + 2F(7/2)(Ce) and 5I6(Ho) + 2F(5/2)(Ce) --> 5I7(Ho) + 2F(7/2)(Ce)between Ho(3+) and Ce(3+) ions, have been employed to select UC pathways to tune the UC radiation. Theoretical investigations based on steady-state equations demonstrate the proposed UC mechanisms and explain well the observed linear increase of the UC red-to-green intensity ratio with the increment of Ce(3+) ion concentrations.
A Wireless Sensor Network-Based Ubiquitous Paprika Growth Management System (2010)

Wireless Sensor Network (WSN) technology can facilitate advances in productivity, safety and human quality of life through its applications in various industries. In particular, the application of WSN technology to the agricultural area, which is labor-intensive compared to other industries, and in addition is typically lacking in IT technology applications, adds value and can increase the agricultural productivity. This study attempts to establish a ubiquitous agricultural environment and improve the productivity of farms that grow paprika by suggesting a 'Ubiquitous Paprika Greenhouse Management System' using WSN technology. The proposed system can collect and monitor information related to the growth environment of crops outside and inside paprika greenhouses by installing WSN sensors and monitoring images captured by CCTV cameras. In addition, the system provides a paprika greenhouse environment control facility for manual and automatic control from a distance, improves the convenience and productivity of users, and facilitates an optimized environment to grow paprika based on the growth environment data acquired by operating the system.
Design and fabrication of the self-aligned opposed gate-source transistor (1992)

The authors report on the modeling, design, and successful realization of the self-aligned opposed gate-source transistor (OGST). An advanced distributed traveling-wave mathematical model of the OGST is used to determine the optimal gate width for 94-GHz operation. A novel fabrication process is described that utilizes a new lithography technique, resonant refractive index lithography, to self-align a 0.15- mu m source to a 0.3- mu m gate on opposite sides of a 0.2- mu m-thick GaAs active layer. The authors report on the DC operating characteristics of the self-aligned OGST and compare these results with theoretical models.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Application of nanocrystalline Fe(or Co-Fe)-Hf-O magnetic films with high electrical resistivity to micro DC-DC converters (1997)

High resistivity magnetic films, such as reactive sputtered Fe-Hf-O and Co-Fe-Hf-O, were applied to multilayered micro reactors for high frequency operation dc-dc converters. For a comparison, an amorphous Co-Ta-Hf film with good soft magnetic properties was also investigated. The micro reactor had the highest quality factor (the lowest loss) when using Co-Fe-Hf-O film with the highest resistivity. In 5 MHz operation of dc-dc converters using these micro reactors, the highest conversion efficiency was obtained when using Co-Fe-Hf-O film.
Crosstalk in SOI Microring Resonator-Based Filters (2015)

We experimentally investigate the interchannel and intrachannel crosstalk of first- and second-order microring resonator (MRR) filters fabricated on a silicon-on-insulator platform. We find that there is an MRR radius that maximizes the wavelength division multiplexing channel count given a waveguide geometry, a maximum tolerable insertion loss, and a minimum permissible adjacent channel isolation. The measured power penalties due to interchannel crosstalk of two-channel demultiplexers based on first-order and series-coupled MRR filters are presented as functions of channel spacing and adjacent channel isolation. Next, we compare the intrachannel crosstalk of first-order, cascaded, and series-coupled MRR add-drop filters. Our results show that first-order MRR devices are unsuitable for simultaneous add-drop operation at high data rates and small channel spacings. Intrachannel crosstalk of cascaded and series-coupled designs are measured as functions of the data rate and the level of detuning between the MRRs. Low intrachannel crosstalk power penalties are demonstrated for cascaded and series-coupled MRR filters for data rates up to 20 Gb/s. Based on the measured results, we present requirements for the input-to-through response of add-drop filters that will ensure low intrachannel crosstalk.
One-Footed and Externally Disturbed Two-Footed Postural Control in Patients With Chronic Low Back Pain and Healthy Control Subjects (1998)

Impaired postural stability seems to be one factor in multidimensional symptomatology of patients with chronic low back trouble. Postural stability is easily disturbed in case of impairment in strength, coordination, or effective coupling of muscles in the lumbar and pelvic area. Patients with chronic low back pain seem to experience impairment in these functions, which should be taken into consideration when back rehabilitation programs are planned.
Follow-Up Designs to Resolve Confounding in Multifactor Experiments (1996)

Fractional factorial, Plackett-Burman, and other multifactor designs are often effective in practice due to factor sparsity. That is, just a few of the many factors studied will have major effects. In those active factors, these designs can have high resolution. We have previously developed a Bayesian method based on the idea of model discrimination that uncovers the active factors. Sometimes, the results of a fractional experiment are ambiguous due to confounding among the possible effects, and more than one model may be consistent with the data. Within the Bayesian construct, we have developed a method for designing a follow-up experiment to resolve this ambiguity. The idea is to choose runs that allow maximum discrimination among the plausible models. This method is more general than methods that algebraically decouple aliased interactions and more appropriate than optimal design methods that require specification of a single model. The method is illustrated through examples of fractional experiments.

Deep and Clear Optical Imaging of Thick Inhomogeneous Samples (2012)

Inhomogeneity in thick biological specimens results in poor imaging by light microscopy, which deteriorates as the focal plane moves deeper into the specimen. Here, we have combined selective plane illumination microscopy (SPIM) with wavefront sensor adaptive optics (wao). Our waoSPIM is based on a direct wavefront measure using a Hartmann-Shack wavefront sensor and fluorescent beads as point source emitters. We demonstrate the use of this waoSPIM method to correct distortions in three-dimensional biological imaging and to improve the quality of images from deep within thick inhomogeneous samples.
Advanced glycation end product (age) inhibitors and their therapeutic implications in diseases. (2004)

Nonenzymatic modification of proteins by reducing sugars, a process that is also known as the Maillard reaction, leads to the formation of advanced glycation end products (AGEs) in vivo. There is a growing body of evidence that formation and accumulation of AGEs progress during normal aging, and at an extremely accelerated rate under diabetes, and are thus involved in the pathogenesis of various diseases such as diabetic vascular complications and neurodegenerative diseases. Therefore, inhibition of AGE formation may be a promising target for therapeutic intervention in AGE-related disorders. In this review, we discuss several types of AGE inhibitors and their therapeutic implications in diseases.

Homocysteine and Hyperhomocysteinaemia (2018)

Homocysteine (Hcy) is a thiol group containing the amino acid, which naturally occurs in all humans. Hcy is degraded in the body through two metabolic pathways, while a minor part is excreted through kidneys. The chemical reactions that are necessary for degradation of Hcy require the presence of folic acid, vitamins B6 and B12. Consequently, the level of the total Hcy in the serum is influenced by the presence or absence of these vitamins. An elevated level of the Hcy, hyperhomocysteinemia (HHcy) and homocystinuria is connected with occlusive artery disease, especially in the brain, the heart, and the kidney, in addition to venous thrombosis, chronic renal failure, megaloblastic anemia, osteoporosis, depression, Alzheimer's disease, pregnancy problems, and others. Elevated Hcy levels are connected with various pathologies both in adult and child population. Causes of HHcy include genetic mutations and enzyme deficiencies in 5, 10-methylenetetrahydrofolate reductase (MTHFR) methionine synthase (MS), and cystathionine β-synthase (CβS). HHcy can be caused by deficiencies in the folate, vitamin B12 and to a lesser extent, deficiency in B6 vitamin what influences methionine metabolism. Additionally, HHcy can be caused by the rich diet and renal impairment. This review presents literature data from recent research related to Hcy metabolism and the etiology of the Hcy blood level disorder. In addition, we also described various pathological mechanisms induced by hereditary disturbances or nutritional influences and their association with HHcy induced pathology in adults and children and treatment of these metabolic disorders.
Learning Bayesian network classifiers for facial expression recognition both labeled and unlabeled data (2003)

Understanding human emotions is one of the necessary skills for the computer to interact intelligently with human users. The most expressive way humans display emotions is through facial expressions. In this paper, we report on several advances we have made in building a system for classification of facial expressions from continuous video input. We use Bayesian network classifiers for classifying expressions from video. One of the motivating factor in using the Bayesian network classifiers is their ability to handle missing data, both during inference and training. In particular, we are interested in the problem of learning with both labeled and unlabeled data. We show that when using unlabeled data to learn classifiers, using correct modeling assumptions is critical for achieving improved classification performance. Motivated by this, we introduce a classification driven stochastic structure search algorithm for learning the structure of Bayesian network classifiers. We show that with moderate size labeled training sets and large amount of unlabeled data, our method can utilize unlabeled data to improve classification performance. We also provide results using the Naive Bayes (NB) and the Tree-Augmented Naive Bayes (TAN) classifiers, showing that the two can achieve good performance with labeled training sets, but perform poorly when unlabeled data are added to the training set.
