Application of the First Higher-Order (M21) Mode Rayleigh Wave to the Inspection of Stainless Steel Overlays (1990)

Efficient inspection of stainless steel overlays appears to present a particularly challenging problem due to the anisotropy that is characteristic of that material. An improved inspection technique may be available, however, when the dissimilar properties of the overlay and the base material are utilized. Higher order mode Rayleigh waves which at high frequencies remain confined to the upper layer of the stainless steel material are demonstrated to be able to detect welding defects in the overlay material in a field some distance away from the probe. With this technique, a larger area may be scanned with each probe placement rather than the point contact probe inspection method that is typically used.
Consequential life cycle assessment of kraft lignin recovery with chemical recycling (2023)

The recovery of kraft lignin from black liquor allows an increasing of the pulp production of a kraft mill (marginal tonnage) and at the same time provide a valuable material that can be used as energy or chemical feedstock. However, because lignin precipitation is an energy- and material-consuming process, the environmental consequences from a life cycle perspective are under discourse. The aim of this study is to investigate, through the application of consequential life cycle assessment, the potential environmental benefits of kraft lignin recovery and its subsequent use as an energy or chemical feedstock. A newly developed chemical recovery strategy was assessed. The results revealed how the use of lignin as energy feedstock is not environmentally advantageous compared to producing energy directly from the pulp mill's recovery boiler. However, the best results were observed when lignin was used as a chemical feedstock in four applications to replace bitumen, carbon black, phenol, and bisphenol-A.

Researches of a WSN with Scale-free Routing Topology (2017)

Based on the topological characteristics of scale-free networks, a kind of wireless sensor network routing algorithm based on scale-free was studied. We did our experiments from a perspective of the average degree distribution and the clustering properties of some high-degree nodes, or the "hot nodes" as we called them. First, we used multi-path principles to build a scale-free network topology based wireless sensor network and robustness is briefly discussed. Then, information fusion ability was introduced to balance network energy and extend the life cycle of the network, as a result of saving traffics. Simulations showed that the routing algorithm has more significant effect on the node degree distribution, reliability and overall performance evaluation once compared with some other WSNs.

Diagnostics and growth control of single-walled carbon nanotube forests using a telecentric optical system for in situ height monitoring (2008)

An in situ telecentric height monitoring system was employed as a standard characterization tool for in situ height monitoring of nanotube forests. We demonstrated that the system possesses a wide dynamic range beyond the centimeter scale, high resolution of 1 μm, free from routine maintenance, simple installation, and use in contrast to previous methods. These features were highlighted by the monitoring of a 5 mm tall forest, the examination of the effect of gas species on growth rates, and the automatic control forest height.
Methacrylate‐based block ionomers I: Synthesis of block ionomers derived from t‐butyl methacrylate and alkyl methacrylates (1994)

Abstract Diblock and triblock copolymers of t ‐butyl methacrylate ( t BMA) with 2‐ethylhexyl methacrylate (EHMA) and n ‐hexyl methacrylate were prepared via alkyl lithium initiation and sequential addition techniques in THF at −78°C. The t BMA blocks were quantiatively and selectively hydrolyzed to afford poly(methacrylic acid) (PMAA) blocks which were then neutralized with alkali metal bases to form block ionomers. The unhydrolyzed copolymers had a phase mixed morphology as evidenced by thermal analysis while the hydrolyzed and neutralized polymers were multiphase materials. The carboxylic acid and ioncontaning triblock copolymers formed gels in nonpolar solvents which could be disrupted by the addition of polar additives. Certain carboxylic acid and ioncontaining EHMA/ t BMA diblock copolymers also showed this behavior. The triblock ionomers did not show thermoplastic flow prior to degradation, except at the lowest ionic content studied (2%).
Gene Mapping in the 20th and 21st Centuries: Statistical Methods, Data Analysis, and Experimental Design (2009)

In the 20th century geneticists began to unravel some of the simpler aspects of the etiology of inherited diseases in humans. The theory of linkage analysis was developed and applied long before the advent of molecular biology, but only the technological advances of the second half of the 20th century made large-scale gene mapping with a dense genome-spanning set of markers a reality. More recently, the primary topic of interest has shifted from simple Mendelian diseases, for which genotypes of some gene are the cause of disease, to more complex diseases, for which genotypes of some set of genes together with environmental factors merely alter the probability that an individual gets the disease, although individual factors are typically insufficient to cause the disease outright. To this end, a great deal of dogma has evolved about the best way to skin this cat, although to date success has been minimal with any approach. We postulate that the main reason for this is a lack of attention to experimental design. Once the data have been ascertained, the most powerful statistical methods will not be able to salvage an inappropriately designed study (Andersen 1990). Each phenotype and/or population mandates its own individually tailored study design to maximize the chances of successful gene mapping. We suggest that careful consideration of the available data from real genotype-phenotype correlation studies (as opposed to oversimplified theoretically tractable models), and the practical feasibility of different ascertainment schemes dictate how one should proceed. In this review we review the theory and practice of gene mapping at the close of the 20th century, showing that most methods of linkage and linkage disequilibrium analysis are similar in a fundamental sense, with the differences being related more to study design and ascertainment than to technical details of the underlying statistical analysis. To this end, we propose a new focus in the field of statistical genetics that more explicitly highlights the primacy of study design as the means to increase power for gene mapping.
Atomic force microscopy examination of conformations of polynucleotides in response to platinum isomers:Significance of GC content at broken ends (2000)

Atomic force microscopy is a technique that enables visualization of macromolecular conformations of polynucleotides at nanometer resolution. We investigated the results of interactions of cisplatin, a DNA binding anticancer drug, and its inactive counterpart, transplatin isomer, on the molecular conformation of polynucleotides: poly d(G-C). poly d(G-C) (polyGC) and poly d(A-T). poly d(A-T) (polyAT). We observed that polyAT exhibited an increased number of enlarged ends of molecules, which we attribute to unwound and/or collapsed regions of polyAT. PolyGC molecules did not show such ends unless cisplatin was added to the PolyGC polymers. Transplatin had the apparent effect of causing overlapping or stacking of the polymer molecules. Addition of exonuclease-III to these polymers removed the visible enlarged ends. The effects of cisplatin as compared to transplatin on the polyGC duplex polymers provide support for the presence of intrastrand covalent linkages, consistent with known N7 guanine interaction of the cis isomer on molecular conformation. Furthermore, our results indicate that the mechanism of interactions of DNA with cisplatin may be dependent on the GC content of the molecules. Int. J. Cancer (Radiat. Oncol. Invest.) 90, 68-72, 2000.
TWEAK Regulates Muscle Functions in a Mouse Model of RNA Toxicity (2016)

Myotonic dystrophy type 1 (DM1), the most common form of muscular dystrophy in adults, is caused by toxic RNAs produced from the mutant DM protein kinase (DMPK) gene. DM1 is characterized by progressive muscle wasting and weakness. Therapeutic strategies have mainly focused on targeting the toxic RNA. Previously, we found that fibroblast growth factor-inducible 14 (Fn14), the receptor for TWEAK, is induced in skeletal muscles and hearts of mouse models of RNA toxicity and that blocking TWEAK/Fn14 signaling improves muscle function and histology. Here, we studied the effect of Tweak deficiency in a RNA toxicity mouse model. The genetic deletion of Tweak in these mice significantly reduced muscle damage and improved muscle function. In contrast, administration of TWEAK in the RNA toxicity mice impaired functional outcomes and worsened muscle histopathology. These studies show that signaling via TWEAK is deleterious to muscle in RNA toxicity and support the demonstrated utility of anti-TWEAK therapeutics.

Molecular Mechanisms of Homologous and Heterologous Desensitization Mediated by Vasopressin in Smooth Muscle Cells (1989)

Arginine vasopressin (AVP) has been shown previously to enhance phosphatidylinositol (PI) turnover and mobilize calcium in the rat aortic smooth muscle cell-line (A10; ATCC CRL 1476) via the V1 receptor (Aiyar, N., Nambi, P., Stassen, F. L., and Crooke, S. T. (1986) Life Sci. 39, 37-45). Exposure of A10 cells to AVP for periods ranging from 5 min to 2 h resulted in 30-40% loss in AVP-binding sites and an inhibition of the production of inositol di- and trisphosphates and the mobilization of calcium when the cells were rechallenged by addition of AVP. We now report that during the same time course AVP induces a dose- and time-dependent decrease in labeled PI, phosphatidylinositol-4-phosphate and phosphatidylinositol-4,5-bisphosphate reaching a minimum after 30 min of incubation. After 2 h of exposure to AVP, the levels of labeled PI, phosphatidylinositol-4-phosphate and phosphatidylinositol-4,5-bisphosphate increased to a new basal level approximately 30% less than the untreated cultures. The decrease in inositol lipid labeling mediated by AVP was inhibited when the V1 antagonist SK&F 100273 was included in the incubations with AVP. No decrease was observed when the V2 agonist 1-deamino, [8-D-arginine]vasopressin was used for pretreatment of the cells. Furthermore, when PI kinase activity was measured in cell extracts from untreated and AVP-treated (2 h) cells a significant decrease (p less than 0.05) was observed in the absence, but not in the presence, of added PI in the AVP-treated cells as compared with the control cells. Thrombin also stimulates PI metabolism and calcium mobilization in these cells and brought about both a prolonged decrease in inositol lipids and inhibition of PI kinase activity. AVP pretreatment affected the release of intracellular Ca2+ induced by AVP, thrombin, and ATP, differently. The time of AVP pretreatment required to induce half-maximal inhibition of intracellular Ca2+ release in response to AVP, thrombin, and ATP was approximately 8, 24, and 30 min, respectively. Consequently, we suggest that the reduction in response to AVP with short term preincubation is due to homologous desensitization as reflected by 30-40% decrease in V1 receptors. Subsequently, a decrease in inositol lipid pools and PI kinase activity results in heterologous desensitization in response to AVP, thrombin, and ATP.
Virtual Sensors: Using Data Mining to Efficiently Estimate Spectra (2004)

Detecting clouds within a satellite image is essential for retrieving surface geophysical parameters, such as albedo and temperature, from optical and thermal imagery because the retrieval methods tend to be valid for clear skies only. Thus, routine satellite data processing requires reliable automated cloud detection algorithms that are applicable to many surface types. Unfortunately, cloud detection over snow and ice is difficult due to the lack of spectral contrast between clouds and snow. Snow and clouds are both highly reflective in the visible wavelen,ats and often show little contrast in the thermal Infrared. However, at 1.6 microns, the spectral signatures of snow and clouds differ enough to allow improved snow/ice/cloud discrimination. The recent Terra and Aqua Moderate Resolution Imaging Spectro-Radiometer (MODIS) sensors have a channel (channel 6) at 1.6 microns. Presently the most comprehensive, long-term information on surface albedo and temperature over snow- and ice-covered surfaces comes from the Advanced Very High Resolution Radiometer ( AVHRR) sensor that has been providing imagery since July 1981. The earlier AVHRR sensors (e.g. AVHRR/2) did not however have a channel designed for discriminating clouds from snow, such as the 1.6 micron channel available on the more recent AVHRR/3 or the MODIS sensors. In the absence of the 1.6 micron channel, the AVHRR Polar Pathfinder (APP) product performs cloud detection using a combination of time-series analysis and multispectral threshold tests based on the satellite's measuring channels to produce a cloud mask. The method has been found to work reasonably well over sea ice, but not so well over the ice sheets. Thus, improving the cloud mask in the APP dataset would be extremely helpful toward increasing the accuracy of the albedo and temperature retrievals, as well as extending the time-series of albedo and temperature retrievals from the more recent sensors to the historical ones. In this work, we use data mining methods to construct a model of MODIS channel 6 as a function of other channels that are common to both MODIS and AVHRR. The idea is to use the model to generate the equivalent of MODIS channel 6 for AVHRR as a function of the AVHRR equivalents to MODIS channels. We call this a Virtual Sensor because it predicts unmeasured spectra. The goal is to use this virtual channel 6. to yield a cloud mask superior to what is currently used in APP . Our results show that several data mining methods such as multilayer perceptrons (MLPs), ensemble methods (e.g., bagging), and kernel methods (e.g., support vector machines) generate channel 6 for unseen MODIS images with high accuracy. Because the true channel 6 is not available for AVHRR images, we qualitatively assess the virtual channel 6 for several AVHRR images.
Cadherin 11 Involved in Basement Membrane Damage and Dermal Changes in Melasma (2015)

Basement membrane (BM) disruption and dermal changes (elastosis, collagenolysis, vascular ectasia) have been reported in melasma. Although ultraviolet (UV) irradiation can induce these changes, UV is not always necessary for melasma development. Cadherin 11 (CDH11), which is upregulated in some melasma patients, has previously been shown to stimulate melanogenesis. Because CDH11 action requires cell-cell adhesion between fibroblasts and melanocytes, BM disruption in vivo should facilitate this. The aim of this study was to examine whether CDH11 overexpression leads to BM disruption and dermal changes, independent of UV irradiation. Immunohistochemistry/immunofluorescence, real-time PCR, Western blotting, and zymography suggested that BM disruption/dermal changes and related factors were present in the hyperpigmented skin of CDH11-upregulated melasma patients and in CDH11-overexpressing fibroblasts/keratinocytes. The opposite was seen in CDH11-knockdown cells. UV irradiation of the cultured cells did not increase CDH11 expression. Collectively, these data demonstrate that CDH11 overexpression could induce BM disruption and dermal changes in melasma, regardless of UV exposure.

Recovering Signals from their FROG Trace (2018)

The problem of recovering a signal from its power spectrum is called phase retrieval. This problem appears in a variety of scientific applications, such as ultra-short laser pulse characterization and diffraction imaging. However, the problem for one-dimensional signals is ill-posed as there is no one-to-one mapping between a one-dimensional signal and its power spectrum. In the field of ultra-short laser pulse characterization, it is common to overcome this ill-posedness by using a technique called Frequency-Resolved Optical Gating (FROG). In FROG, the measured data, referred to as FROG trace, is the Fourier magnitude of the product of the underlying signal with several translated versions of itself. Therefore, in order to recover a signal from its FROG trace, one needs to invert a system of phaseless quartic equations. In this paper, we explore the symmetries and uniqueness of the FROG mapping. Our main result states that a signal bandlimited to B is determined uniquely, up to symmetries, by only 3B FROG measurements.
Visualization for a Multi-Sensor Data Analysis (2006)

This work describes our efforts in creating the software in order to analyze the multi-sensor data for gas transmission pipeline inspection. The amount of data is usually considerable because the hardware system that consists of multiple heterogeneous sensors records multi-sensor values for long-distance inspection. It imposes a heavy burden on the operators who should sieve the huge and complex data, detect features of the pipeline and decide a feature as a significant defect. In our system, the virtual 3D pipeline helps the user to examine the inside of pipeline intuitively by navigating according to the realistic pipeline trajectory. We mapped the geographical data of the pipeline and heterogeneous sensor data on the virtual 3D pipeline. Moreover, our system offer the various feature detail views to help the users rapid and precise decision. Users can switch the navigation mode and the feature detail mode easily. Consequently, the virtual pipeline plays a role as an intuitive interaction metaphor for pipeline inspection
