Improving meeting summarization by focusing on user needs (2009)

Advances in multimedia technologies have enabled the creation of huge archives of audio-video recordings of meetings, and there is burgeoning interest in developing meeting browsers to help users better leverage these archives. A recent study has shown that extractive summaries provide a more efficient way of navigating meeting content than simply reading through the transcript and using the audio-video record, or navigating via keyword search (Murray, 2007). The extractive summary technique identifies informative dialogue acts to generate general purpose summaries. These summaries can still be lengthy. Recently, we have developed a decision-focused summarization system that presents only 1-2% of the recordings related to decision making. In this paper, we describe a task-based evaluation in which we compare the decision-focused summaries to the general purpose summaries. Our results indicate that the more focused summaries help users perform the decision debriefing task more effectively and improve perceived efficiency. In addition, this study also investigates the effect of automatic summaries and transcription on task effectiveness, report quality, and users' perceptions of task success.
Designs and Implementations of Automated Systems for Pavement Surface Distress Survey (2000)

The categorization and quantification of the type, severity, and extent of surface distress is a primary method for assessing the condition of highway pavements. Various methodologies were developed to automate pavement distress surveys. Significant technical advances were made during the past years. The implementations of the image capturing subsystems include conventional analog-based area-scan, analog and digital line-scan, laser scanning, and shadow Moire method. Newer implementations of image processing include artificial neural net and parallel processing. However, problems still exist in the areas of implementation costs, processing speed, repeatability, and accuracy. This paper presents some of the key developments in recent years for automating pavement distress evaluation. These new systems are described in terms of their potential and applicability. This paper also presents a modified approach to collecting and processing surface distress through the use of high-performance digital cameras for the acquisition of surface distress data.
[Determination of CD34(+) cells in mobilized peripheral blood by flow cytometry]. (2002)

To explore a simple and effective method to determinate the volume of CD34(+) cells in the peripheral blood of donors received drug mobilization for stem cell transplantation by using flow cytometry, the mobilized peripheral blood from donors and 100 micro l fresh whole blood were labeled with monoclonal antibodies Anti-CD34-PE and Anti-CD45-FITC, after lying the red blood cells, and assessed with flow cytometer FL2 (log) vs SSC (log) and FL1 (log) vs SSC (log) were mainly used for analysis windows. The results showed that a level of CD34(+) cells in whole nucleated cells as low as 0.05% - 0.1% can be detected effectively using this method when 10(5) nucleated cells were counted. At day 5 or day 6, the level of CD34(+) cells in most samples of patients reached a peak volume, some of samples and the levels were more than one percent in. It was concluded that CD34(+) cells can be effectively determined by using this method. According to the relative rate of CD34(+) cells, the time to harvest the stem cells in blood can be determined.
Synthesizing distributed buffer clock trees for high performance ASICs (2002)

An integrated design system is presented in this paper for synthesizing high performance clock distribution networks for application to high speed ASICs. An optimal clock skew schedule is determined which provides a set of localized non-zero clock skew values that improve both circuit performance and reliability. These clock skew values together with the functional hierarchy are used to design the topology of the clock distribution network and to determine the minimum clock path delays which satisfy the clock skew schedule. Distributed buffers targeted for CMOS technology are synthesized to emulate the delay values assigned to the individual branches of the clock tree. Maximum errors of less than 2.5% for the delay of the clock paths and 4% for the clock skew between any two registers belonging to the same global data path as compared with SPICE Level-3 are demonstrated for an example circuit.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Tests of an Improved Rotating Stall Control System on a J-85 Turbojet Engine (1980)

An improved version of a rotating stall control system has been tested successfully on a J-85-B turbojet engine. Past tests had pointed out the desirability of increasing the response speed of the control. In this study, the installation of the stall control on the J-85 was modified so as to decrease the response time of the control by a factor of ten over that attained in the past tests. The modified control was tested to see if the decreased response time improved the ability to clear rotating stall once it has started, and also to see if rotating stall could be anticipated and prevented by proper selection of the variables in the stall control detection system. The performance of the stall control was tested by closing the bleed doors on the engine until rotating stall occurred or until the control anticipated stall and held the bleed doors open. The tests showed that the control is capable of anticipating stall before it occurs and keeping the engine completely clear of stall at speeds up to 80 percent of design speed. No tests were performed above 80 percent of design speed because opening the bleed doors at such speeds might aggravate the stall rather than clear it.
U‐Pb Zircon Geochronology with an Integrated LA‐ICP‐MS Microanalytical Workstation: Achievements in Precision and Accuracy (2009)

Laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) is a microanalytical tool especially suitable for providing fast and precise U‐Pb geochronological results on zircon grains. A new 193 nm excimer laser adapted to a micromachining workstation, equipped with a newly designed two‐volume ablation cell and coupled with a quadrupole ICP‐MS, is presented here. The system was tuned routinely to achieve sensitivities in the range of 3000 cps/μg g −1 for 238 U (< 2% RSD), with a 34 μm spot size, at 5 Hz and ∼ 8 J cm −2 , while ablating the NIST SRM 612 glass reference material. The system was capable of providing fast (< 1.5 minutes each analysis) and precise (generally < 1.5% 1s errors) 206 Pb/ 238 U zircon ages. The ages of widely used reference material zircons (Plesovice, 337 Ma; Temora, 416 Ma; R33, 418 Ma; Sri Lanka, 564 Ma; 91500, 1065 Ma) could be precisely matched, with an accuracy on isotopic ratios that ranged from ∼ 2 to ∼ 6%, depending on the homogeneity of the natural reference materials.
Design Considerations for Indoor Wireless Transmission between a Body-Worn Physiological Monitoring Device and a Gateway in a Home Environment (2016)

This paper describes the technical tradeoffs that should be considered for the design of an on-body wireless link for physiological monitoring in an indoor environment. The desire to minimize the physical size of the on-body device, typically driven by comfort and aesthetic considerations, affects antenna performance to varying degrees, depending on the selected operating frequency of the wireless communications link. In addition, the complex indoor propagation environment also exerts a significant influence on communications system performance. An analytical analysis and simulation results exploring these topics are presented, followed by a design example and measurement results of an on-body device and gateway performance in a typical home environment.
Doping-Induced Lattice Mismatch and Misorientation in 4H-SiC Crystals (2012)

The c - and a -lattice constants of nitrogen-doped 4H-SiC were measured in the wide temperature range (RT - 1100°C). The samples used in this study were heavily doped substrates and lightly-doped free-standing epilayers. The lattice constants at room temperature are almost identical for all the samples. However, the lattice contraction by heavy nitrogen doping was clearly observed at high temperatures, which indicates that the thermal expansion coefficients are dependent on the nitrogen concentration. The lattice mismatch (Δ d/d ) between a lightly-doped free-standing epilayer (N d = 6x10 14 cm -3 ) and a heavily-doped substrate (N d = 2x10 19 cm -3 ) was calculated as 1.7x10 -4 at 1100°C. The authors also investigated lattice constants of high-dose N + , P + , and Al + -implanted 4H-SiC. Reciprocal space mapping (RSM) was utilized to investigate the lattice mismatch and misorientation. The RSM images show the c -lattice expansion and c -axis tilt of the ion-implanted layers, irrespective of ion species. The authors conclude that the lattice expansion is not caused by heavy doping itself, but by secondary defects formed after the ion-implantation and activation-annealing process.
Competition of Superconducting Phenomena and Kondo Screening at the Nanoscale (2011)

Magnetic and superconducting interactions couple electrons together to form complex states of matter. We show that, at the atomic scale, both types of interactions can coexist and compete to influence the ground state of a localized magnetic moment. Local spectroscopy at 4.5 kelvin shows that the spin-1 system formed by manganese-phthalocyanine (MnPc) adsorbed on Pb(111) can lie in two different magnetic ground states. These are determined by the balance between Kondo screening and superconducting pair-breaking interactions. Both ground states alternate at nanometer length scales to form a Moiré-like superstructure. The quantum phase transition connecting the two (singlet and doublet) ground states is thus tuned by small changes in the molecule-lead interaction.
Altered Ultrasonic Vocalization and Impaired Learning and Memory in Angelman Syndrome Mouse Model with a Large Maternal Deletion from Ube3a to Gabrb3 (2010)

Angelman syndrome (AS) is a neurobehavioral disorder associated with mental retardation, absence of language development, characteristic electroencephalography (EEG) abnormalities and epilepsy, happy disposition, movement or balance disorders, and autistic behaviors. The molecular defects underlying AS are heterogeneous, including large maternal deletions of chromosome 15q11-q13 (70%), paternal uniparental disomy (UPD) of chromosome 15 (5%), imprinting mutations (rare), and mutations in the E6-AP ubiquitin ligase gene UBE3A (15%). Although patients with UBE3A mutations have a wide spectrum of neurological phenotypes, their features are usually milder than AS patients with deletions of 15q11-q13. Using a chromosomal engineering strategy, we generated mutant mice with a 1.6-Mb chromosomal deletion from Ube3a to Gabrb3, which inactivated the Ube3a and Gabrb3 genes and deleted the Atp10a gene. Homozygous deletion mutant mice died in the perinatal period due to a cleft palate resulting from the null mutation in Gabrb3 gene. Mice with a maternal deletion (m-/p+) were viable and did not have any obvious developmental defects. Expression analysis of the maternal and paternal deletion mice confirmed that the Ube3a gene is maternally expressed in brain, and showed that the Atp10a and Gabrb3 genes are biallelically expressed in all brain sub-regions studied. Maternal (m-/p+), but not paternal (m+/p-), deletion mice had increased spontaneous seizure activity and abnormal EEG. Extensive behavioral analyses revealed significant impairment in motor function, learning and memory tasks, and anxiety-related measures assayed in the light-dark box in maternal deletion but not paternal deletion mice. Ultrasonic vocalization (USV) recording in newborns revealed that maternal deletion pups emitted significantly more USVs than wild-type littermates. The increased USV in maternal deletion mice suggests abnormal signaling behavior between mothers and pups that may reflect abnormal communication behaviors in human AS patients. Thus, mutant mice with a maternal deletion from Ube3a to Gabrb3 provide an AS mouse model that is molecularly more similar to the contiguous gene deletion form of AS in humans than mice with Ube3a mutation alone. These mice will be valuable for future comparative studies to mice with maternal deficiency of Ube3a alone.
Sustained Long Term Potentiation and Anxiety in Mice Lacking theMas Protooncogene (1998)

The Mas protooncogene is a maternally imprinted gene encoding an orphan G protein-coupled receptor expressed mainly in forebrain and testis. Here, we provide evidence for a function of Mas in the central nervous system. Targeted disruption of the Mas protooncogene leads to an increased durability of long term potentiation in the dentate gyrus, without affecting hippocampal morphology, basal synaptic transmission, and presynaptic function. In addition, Mas-/- mice show alterations in the onset of depotentiation. The permissive influence of Mas ablation on hippocampal synaptic plasticity is paralleled by behavioral changes. While spatial learning in the Morris water maze is not significantly influenced, Mas-deficient animals display an increased anxiety as assessed in the elevated-plus maze. Thus, Mas is an important modulating factor in the electrophysiology of the hippocampus and is involved in behavioral pathways in the adult brain.
The Dry Coal Anomaly – The Horseshoe Canyon Formation of Alberta, Canada (2005)

Abstract The Horseshoe Canyon coal formation in Alberta, Canada is an anomaly for coals. It is dry, for the most part producing no formation water. Therefore, no dewatering is required. In fact, it is severely damaged by water influx. Normal permeability injection tests and conventional hydraulic fracturing techniques, even foams, have been unsuccessful in this environment. The best part of this reservoir has an areal extent in excess of 12,000 square miles containing 1-2 BCF per square mile of recoverable gas. Commercial development of this resource is a very appealing prospect. Numbers of coal seams vary from 5 to 30 per well, spread out over 600 – 1,300 ft. Individual seam thicknesses vary from 1 to 13 ft. Most seams are discontinuous over a large area. The better part of the formation has permeability in the range of 1 – 100 md. This makes it difficult to avoid damaging the formation during drilling and cementing operations, hence some type of stimulation is required. Nitrogen hydraulic fracturing is the only stimulation process that has had any success in this formation to date. The treatments involve pumping nitrogen at high rates, without proppant, through coiled tubing (CT) and a selective cup-type packer (SCP), isolating each coal seam while treating it. Bottomhole treating gradients vary greatly with an average of approximately 2.2 psi/ft. Whether these nitrogen treatments are in fact fracturing the formation or just having the damage flushed out has been a matter for speculation. Over 1,600 wells have been treated in this way and more continue to be added on an everyday basis. This paper describes the formation characteristics and geology of the Horseshoe Canyon coal and presents case histories of hydraulic fracturing treatments performed including production results.
Generation and characterization of hamster-mouse hybridomas secreting monoclonal antibodies with specificity for lipopolysaccharide receptor. (1990)

Experiments are described for the partial purification of the 80-kDa LPS binding protein expressed on macrophages and lymphocytes. This partially purified Ag was used to immunize adult Armenian hamsters and splenocytes from immunized animals were fused with murine myeloma cell lines. Hybridoma cell culture supernatants containing mAb were screened by ELISA for positive binding to the immunizing Ag, murine splenocytes and the murine 70Z/3 pre B cell and for an absence of binding to sheep E. Positive clones were further screened for reciprocal competitive binding with LPS on spleen cells and ability to modulate B lymphocyte mitogenic activity. Two hybridoma cell lines secreting IgM monoclonals, termed mAb3D7 and mAb5D3, were identified that satisfied all of the selection criteria. These hybridoma cell lines were subcloned and expanded. Binding of one (mAb3D7) was abrogated by treatment of Ag with mild periodate; binding of the second (mAb5D3) was destroyed by digestion of Ag with proteinase K. Binding specificity for mAb5D3 has been confirmed by ELISA using highly purified 80-kDa protein. These mAb have been of value in establishing that the 80-kDa LPS binding protein previously identified may serve as a specific functional receptor for LPS.

Magnetic damping constant of Co2FeSi Heusler alloy thin film (2007)

Co 2 Fe Si films were prepared using magnetron sputtering technique on Cr buffer layers and MgO(001) substrates at various annealing temperatures. We investigated the crystal structures, magnetic properties (Ms and Hc), surface roughness, and magnetic damping constants (α) of the prepared Co2FeSi films. Out-of-plane angular dependences of the resonance field and the linewidth of the ferromagnetic resonance spectra were measured and fitted using the Landau-Lifshitz-Gilbert equation to determine the damping constant. The as-deposited Co2FeSi film exhibited an amorphous and disordered structure; the α value was 0.008. In contrast, the Co2FeSi films annealed over 300°C showed epitaxial growth and had a (001)-oriented and L21 ordered structure. Both disordered and L21 ordered Co2FeSi films showed similar α values.
Reaction Mechanism of the Decomposition of Acetic Acid on Illuminated TiO<sub>2</sub> Powder Studied by Means of <i>in Situ</i> Electron Spin Resonance Measurements (1996)

The existence of methyl radicals in the photo-Kolbe reaction was confirmed by means of in situ measurements with flow electron spin resonance for deuterated acetic acid. From the dependence of the flow rate, two reaction paths were deduced for methyl radical formation. These were assigned to those caused by trapped holes and •OH radicals. It is suggested that the former path is dominant when platinum has not been loaded onto TiO2 powder.
Issues of Data Aggregation Methods in Wireless Sensor Network: A Survey (2015)

In Wireless Sensor Networks (WSN) sensor nodes are deployed in a region to sense the information. These sensor nodes sense the similar information and sends it to sink node. This thing leads to redundancy at sink node. Sink node wastes most of its energy in processing redundant packets. To save the energy of node in order to prolong the network lifetime there is need to eliminate redundancy. Data aggregation is a process in which intermediate node receives multiple input packets performs aggregation and produce single output packet in the network. This process will reduce the number of redundant packets in the network. But redundancy sustains reliability. Therefore there is need to maintain redundancy but it should be up to an adequate level. In this paper we have focused on different issues in data aggregation process such as delay, redundancy elimination, accuracy and traffic load and mentioned various methods to solve those issues and then we compared some data aggregation techniques based on strategy, delay, redundancy, average energy consumption and traffic load. Further we have proposed a model based on our study which performs data aggregation at multiple levels and not only maintains the tradeoff between energy conservation and reliability but also addresses all the issues in data aggregation technique.
Evaluating the relationship between user interaction and financial visual analysis (2008)

It has been widely accepted that interactive visualization techniques enable users to more effectively form hypotheses and identify areas for more detailed investigation. There have been numerous empirical user studies testing the effectiveness of specific visual analytical tools. However, there has been limited effort in connecting a user’s interaction with his reasoning for the purpose of extracting the relationship between the two. In this paper, we present an approach for capturing and analyzing user interactions in a financial visual analytical tool and describe an exploratory user study that examines these interaction strategies. To achieve this goal, we created two visual tools to analyze raw interaction data captured during the user session. The results of this study demonstrate one possible strategy for understanding the relationship between interaction and reasoning both operationally and strategically.
Novel anti-glioblastoma agents and therapeutic combinations identified from a collection of FDA approved drugs (2014)

Disk-loaded monopoles with parallel strip elements (1998)

Design considerations and experimental performance data are presented for disk-loaded folded monopoles in which the vertical elements consist of flat parallel strips separated by a dielectric. The presence of the dielectric and the flat strip geometry permit control of resonance frequency, susceptance slope, and impedance step-up ratio over ranges suitable for the design of electrically small antennas with a broad double-tuned response. Graphs are presented giving the impedance step-up ratio due to folding for various strip dimensions derived from static calculations. Experimental results are shown for antennas with heights in the range of one-eighth to one-tenth wavelength.
