Matching images under unstable segmentations (2008)

Region based features are getting popular due to their higher descriptive power relative to other features. However, real world images exhibit changes in image segments capturing the same scene part taken at different time, under different lighting conditions, from different viewpoints, etc. Segmentation algorithms reflect these changes, and thus segmentations exhibit poor repeatability. In this paper we address the problem of matching regions of similar objects under unstable segmentations. Merging and splitting of regions makes it difficult to find such correspondences using one-to-one matching algorithms. We present partial region matching as a solution to this problem. We assume that the high contrast, dominant contours of an object are fairly repeatable, and use them to compute partial matching cost (PMC) between regions. Region correspondences are obtained under region adjacency constraints encoded by region adjacency graph (RAG). We integrate PMC in a many-to-one label assignment framework for matching RAGs, and solve it using belief propagation. We show that our algorithm can match images of similar objects across unstable image segmentations. We also compare the performance of our algorithm with that of the standard one-to-one matching algorithm on three motion sequences. We conclude that our partial region matching approach is robust under segmentation irrepeatabilities.
Dynamics and Regulation of TSH Secretion by Superfused Anterior Pituitary Cells (1981)

Superfused dispersed cells respond rapidly to 2- to 10-min pulses of TRH (10(-10) to 10(-7) M) in a dose-dependent manner. The effects of decreasing the stimulus duration can be overcome by a proportional increase in concentration of TRH. A TRH stimulus of 10 min or greater duration results in a sharp peak in TSH secretion followed by a lower plateau. Somatostatin (10(-8) M inhibits the response to TRH (t X 10(-9) M). T3 (2.0 microgram/dl) inhibits TRH-induced TSH secretion by superfused pituitary fragments, but not by dispersed cells. Corticosterone (50 microgram/dl), however, inhibits crude CRF-induced ACTH secretion by such cells.

On the Granularity of Trie-Based Data Structures for Name Lookups and Updates (2019)

Name lookup is an essential function but a performance bottleneck in both today's and future network architectures. Trie is an excellent candidate data structure and has been widely used for looking up and updating names. However, the granularity of trie-at bit, byte (character), or component level-can dramatically affect the network performance in terms of memory usage and packet-processing speed, which has not yet been studied adequately. To fill this gap, we first show that the choice of trie's granularity for name lookups and updates (i.e., insertions and removals) is not a trivial problem due to the complex performance tradeoffs involved. We also introduce a new tool, called NameGen, which uses a Markov-based name learning model and generates pseudo-real datasets with different tunable name characteristics. We compare different trie granularities based on a collection of datasets and performance metrics, highlight the strengths and weaknesses of each granularity, and draw a conclusion on the choice of granularity. Surprisingly, our experimental evaluation finds that there are only two key rules to choose the proper trie's granularity for any kind of dataset: 1) bit-level trie is the choice when the memory requirement is a real concern and 2) character- and component-level tries are preferred for faster lookups and updates when dealing with names composed of short and long components, respectively.
Using an Oxide Nanoarchitecture To Make or Break a Proton Wire (2005)

We report that long-range proton diffusion (>0.3 mm) is generated in monolithic ultraporous manganese oxide nanoarchitectures upon exposure to gas-phase water. The sol-gel-derived ambigel nanoarchitectures, with bicontinuous networks of covalently bonded nanoscale solid and through-connected mesopores, exhibit conductometric sensitivity to humidity as established by impedance spectroscopy. The spectra contain a Warburg feature from which the concentration and diffusion length of the protonic charge carriers are determined. Water adsorbs conformally onto the architecture's continuous solid network in equilibrium with atmospheric humidity to create a continuous water sheath that acts as a 3-D proton wire. As a result, monolithic manganese oxide ambigels exhibit an equilibrium conductometric response to humidity that is 14 times greater than that of previous reports for electrolytic manganese oxide. A packed bed of 1-10-microm ambigel particulates in physical contact with one another, each with the same nanoscale morphology as the monolithic nanoarchitecture, also support long-range proton diffusion; however, the sensitivity to humidity is four times lower than the monolithic form due to restricted proton transport between adjacent particulates. Films composed of 0.3-12-microm ambigel particulates supported on interdigitated array electrodes with 20-microm electrode spacing express finite-diffusion behavior due to the short distance between the contact electrodes and have a conductometric sensitivity to humidity comparable to electrolytic MnO2 and 17 times lower than the monolithic ambigel. These results suggest that controlling the nature of the porous and solid phases in a nanoarchitecture provides a mechanism to limit interference from condensed water in conductometric gas-phase sensors. In addition, continuous monolithic architectures should improve electrochemical performance in devices where efficient long-range transport of protons or other ions is critical.

Comparative sequence analysis of the capsular polysaccharide loci of Actinobacillus pleuropneumoniae serovars 1–18, and development of two multiplex PCRs for comprehensive capsule typing (2018)

Problems with serological cross-reactivity have led to development of a number of PCRs (individual and multiplex) for molecular typing of Actinobacillus pleuropneumoniae, the causative agent of porcine pleuropneumonia. Most of these assays were developed for detection of specific amplicons within capsule biosynthetic genes before the availability of complete sequences for the different serovars. Here we describe comparative analysis of the complete capsular loci for all 18 serovars of A. pleuropneumoniae, and development of two multiplex PCRs for comprehensive capsule typing of this important pig pathogen.
In vitro fermentation of selected fibrous substrates by dog and cat fecal inoculum: influence of diet composition on substrate organic matter disappearance and short-chain fatty acid production (1995)

Two in vitro fermentation experiments were conducted to evaluate the influence of source of dietary fiber fed to dogs and cats on fermentative activity of their fecal microflora. In Exp. 1, six English Pointer dogs were fed a diet containing either a non-fermentable fiber (Solka Floc) or a fermentable fiber (citrus pulp). A fecal sample from each dog was used as the inoculum source to determine in vitro OM disappearance (OMD) and short-chain fatty acid (SCFA) production from selected fibrous substrates. When data were pooled across substrates and fermentation times, a lower (P = .02) OMD (24.8 vs 29.4%) and a higher (P = .01; 3.8 vs 2.2) acetate to propionate ratio (A:P) occurred for the Solka Floc than for the citrus pulp diet. In Exp. 2, six short-hair cats were fed a diet containing no supplemental fiber (NF) or a diet containing beet pulp (BP). When data were pooled across substrates and fermentation times, NF resulted in a greater (P < .01) A:P than the BP diet (3.4 vs 1.5). The BP treatment resulted in a slightly higher (P = .07) OMD (42.0 vs 39.3%) and a higher (P = .07) propionate production (.74 vs .47 mmol/g of OM) than the NF diet. In summary, in vitro substrate OMD increased and A:P decreased when fecal inoculum from dogs and cats fed diets containing a supplemental source of fermentable fiber was used. In vitro fermentation of fibrous substrates by fecal microflora from dogs and cats increased with inclusion of fermentable fiber in the diet.
Detonation Propagation in Shock-Compressed Liquid Explosives (2004)

The propagation of detonation in a liquid explosive (nitromethane) that has been precompressed by a shock wave is investigated experimentally. An explosive donor charge is used to transmit a shock wave into a capsule containing a tube of test explosive (sensitized nitromethane) perpendicular to the direction of the compressing shock wave. The shock wave compresses the liquid in the test capsule, then reflects from a steel anvil and further compresses the liquid. A detonation then propagates through the tube of shock‐compressed liquid at velocities as large at 7.5 km/s. Propagation of the detonation is recorded with an electronic streak camera, and the degree of compression is measured using a manganin gauge. The observed velocity as a function of the degree of compression is compared to predictions of detonation velocity as a function of density.

Vorasidenib (AG-881): A First-in-Class, Brain-Penetrant Dual Inhibitor of Mutant IDH1 and 2 for Treatment of Glioma (2020)

Inhibitors of mutant isocitrate dehydrogenase (mIDH) 1 and 2 cancer-associated enzymes prevent the accumulation of the oncometabolite d-2-hydroxyglutarate (2-HG) and are under clinical investigation for the treatment of several cancers harboring an IDH mutation. Herein, we describe the discovery of vorasidenib (AG-881), a potent, oral, brain-penetrant dual inhibitor of both mIDH1 and mIDH2. X-ray cocrystal structures allowed us to characterize the compound binding site, leading to an understanding of the dual mutant inhibition. Furthermore, vorasidenib penetrates the brain of several preclinical species and inhibits 2-HG production in glioma tissue by >97% in an orthotopic glioma mouse model. Vorasidenib represents a novel dual mIDH1/2 inhibitor and is currently in clinical development for the treatment of low-grade mIDH glioma.
Tough Composite Hydrogels with High Loading and Local Release of Biological Drugs (2018)

Hydrogels are under active development for controlled drug delivery, but their clinical translation is limited by low drug loading capacity, deficiencies in mechanical toughness and storage stability, and poor control over the drug release that often results in burst release and short release duration. This work reports a design of composite clay hydrogels, which simultaneously achieve a spectrum of mechanical, storage, and drug loading/releasing properties to address the critical needs from translational perspectives. The clay nanoparticles provide large surface areas to adsorb biological drugs, and assemble into microparticles that are physically trapped within and toughen hydrogel networks. The composite hydrogels demonstrate feasibility of storage, and extended release of large quantities of an insulin-like growth factor-1 mimetic protein (8 mg mL<sup>-1</sup> ) over four weeks. The release rate is primarily governed by ionic exchange and can be upregulated by low pH, which is typical for injured tissues. A rodent model of Achilles tendon injury is used to demonstrate that the composite hydrogels allow for highly extended and localized release of biological drugs in vivo, while demonstrating biodegradation and biocompatibility. These attributes make the composite hydrogel a promising system for drug delivery and regenerative medicine.
A 65nm CMOS 30dBm class-E RF power amplifier with 60% power added efficiency (2008)

A 30 dBm single-ended class-E RF power amplifier (PA) is fabricated in 65 nm CMOS technology. The PA is a cascode stage formed by a standard thin-oxide device and a high voltage extended-drain thick-oxide device. Both devices are implemented in a standard sub-micron CMOS technology without using extra masks or processing steps. The proposed PA uses an innovative self-biasing technique to ensure high power-added efficiency (PAE) at both high output power (Pout) and power back-off levels. At 2 GHz, the PA achieves a PAE of 60% at a Pout of 30 dBm and a PAE of 40% at 16 dB back-off.

Towards energy conservation in campus using Wireless Sensor Network (2017)

Educational institutions, should set a role model, in the reduction of the carbon foot print, to protect mother earth. In this paper we focus on designing a Wireless Sensor Network (WSN) based system, which can efficiently conserve the energy of class rooms and labs. We have identified temperature, light, pressure sensors to be utilized for this application. Infra Red receiver and transmitter is used to detect an event whether a person is leaving the room or not. Server room is checked for humidity, temperature, smoke by an integrated sensor, which sends the sensed data to the cloud. So all the sensors send the data periodically to the cloud, which processes the collected data and send the triggered response to the necessary output device and message the facility manager to take administrative actions. The status of each room in each floor is ultimately received at the central monitoring station at the ground floor of the building. The proposed system is designed in such a manner, it can be replicated cost-efficiently in multiple buildings within a campus by using low cost sensors and with the existing communication devices. Therefore this Green Campus System (GCS) design based on wireless sensor networks help in meeting the target of sustainable cities by reducing the overall energy consumption and improving the efficiency in the energy resource management.
Iron-organic frameworks as effective fenton-like catalysts for peroxymonosulfate decomposition in advanced oxidation processes (2023)

Abstract Although Fenton-like reactions have been extensively used to treat various organic contaminants in wastewaters (oily wastewaters, landfill leachate, denitrification with Fenton oxidized non-degradable large molecular organic pollutants, and removal of phosphorus, etc.), the difficulty in catalyst recovery and the instability of catalytic activity limit their practical application. Herein, iron atoms were inserted in a metal-organic framework (FeNC) with dual reaction sites as highly reactive and stable electro-Fenton-like catalysts for the catalytic oxidation of organic pollutants via the electro-Fenton-like activation reaction of peroxymonosulfate (PMS) with fractional leaching of metal ions. Experiments and density functional theory (DFT) calculations indicate that FeNC with FeN 4 and Fe–Fe active sites can rapidly deliver electrons for PMS dissociation. Further, an electrolysis reactor was constructed for the on-site generation of reactive oxygen species, which can stably and continuously purify various organic wastewaters. The combined use of an electrolysis reactor and magnetic catalyst in the current study provides a direction for the long-term remediation of organic pollutants on an industrial scale.
Supplementary Figure 6 from SIRT1 Pathway Dysregulation in the Smoke-Exposed Airway Epithelium and Lung Tumor Tissue (2023)

&lt;p&gt;PDF file, 38K, SIRT1 copy number changes in the Cancer Cell Line Encyclopedia (CCLE) dataset. The dataset consists of both gene expression (measured by Affymetrix HGU133 Plus 2.0 microarrays) and DNA copy number data (measured by Affymetrix SNP 6.0 microarrays) across 991 cancer cell lines. A. Across the 174 lung cancer cell lines, copy number values for SIRT1 in the CCLE dataset are in the insignificant range (dark gray, from -1 to 1), indicating that there is not a loss or amplification of the SIRT1 locus in lung tumors; in contrast, the values for MYC, range from -1 to 3 (light gray). B. SIRT1 and C. MYC pathway activation were predicted across the cancer cell lines using the SIRT1 signature and a MYC signature derived in human mammary epithelial cells (17). There is a significant Pearson correlation between MYC pathway activation and MYC copy number (r=0.51, p&lt;&lt;0.001) but not between SIRT1 pathway activation and SIRT1 copy number (r=0.14, p=0.07), suggesting that decreases in SIRT1 pathway activation are not due to copy loss at the locus. The results are derived by performing RMA as described in the manuscript using the ENTREZ Gene CDF file on each of the 14 batches of CCLE CEL files. Pathway predictions were made using either the SIRT1 or MYC signature across each batch of the CCLE dataset, the predictions from each batch were combined, and lung cancer cell lines were separated out for the analyses in B and C.&lt;/p&gt;

Improved YBCO Coated Conductors Using Alternate Buffer Architectures (2005)

The Rolling-Assisted Biaxially Textured Substrates (RABiTS) process has been identified as one of the leading candidates for the fabrication of high performance YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// (YBCO) coated conductors. The RABiTS process uses standard thermomechanical processing to obtain long lengths of flexible, biaxially oriented substrates with smooth surfaces. The strong biaxial texture of the metal is then transferred to the superconductor by the deposition of intermediate oxide buffers that serve both as a chemical and structural buffer. The typical three-layer RABiTS architecture consists of an e-beam Y/sub 2/O/sub 3/ seed, sputtered YSZ barrier and a sputtered CeO/sub 2/ cap layer. Chemical solution deposition of buffer layers offers potential cost advantage relative to physical vapor deposition (PVD) processes. Our main goal of this study is to develop simplified buffer architectures and demonstrate high J/sub c/ Metal-Organic Deposition (MOD)-YBCO films on all-MOD buffers. La/sub 2/Zr/sub 2/O/sub 7/ (LZO)/CeO/sub 2/ buffers have been identified as potential candidates for this study. MOD-YBCO films with a critical current, I/sub c/ of 212 A/cm have been achieved on MOD-LZO seeds with sputtered YSZ and CeO/sub 2/ cap layers. In addition, MOD-YBCO films with a critical current, I/sub c/ of 140 A/cm have been achieved on all MOD buffers of LZO/CeO/sub 2/ for the first time. This offers a potential toward fabrication of lower cost YBCO coated conductors.

Influence of pulp type on the three-dimensional thermomechanical convertibility of paperboard (2019)

This study examines the effect of pulp type on the formability and elongation of paperboard, which are of key importance when producing 3D packages. Material performance was studied with a press-forming machine using laboratory handsheets as substrates. The handsheets were prepared from bleached softwood and hardwood kraft pulps, chemi-thermomechanical pulp, recycled newsprint, and mixtures of birch kraft and other pulps. The effect of microfibrillated cellulose (MFC) on substrate properties and material formability was also investigated. The 3D elongation of MFC-free handsheets varied between 1.2 and 5.5%. Depending on the pulp type and sheet composition, three essential sheet properties were recognized. These properties were bulk, elastic modulus and bending stiffness, the first two of which affect material bending stiffness. Sheets made from softwood fibers were superior to other samples, but their low bending stiffness resulted in distortion of formed trays. A partial replacement of birch kraft with recycled newsprint did not lead to a loss of sheet extensibility, which suggests that the interactions between the converting tools and the substrate have a great effect on material convertibility. Scanning electron micrographs showed that the pulp type affects the mechanism behind fracture initiation. The ability of MFC to increase extensibility was limited to mechanical pulps, indicating the important role of the main pulp component in defining tensile properties.
