On stereo image coding (2003)

An approach to stereo image compression based on disparity compensation is proposed and evaluated. The scheme is motivated by the suppression theory in human vision. A methodology for evaluating compressed stereo images is proposed. It is based on time measurements of depth perception tasks performed by human subjects. Subjects taking part in the experiment were exposed to displays of stereo images, some of which had been compressed, and were asked to judge the relative depth within each display as fast as possible. Decision times were measured and used as the major dependent variable. It was found that very deep compression of one of the images of a stereo pair does not interfere with the perception of depth in the stereo image.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Templated Porous Carbons:  A Review Article (2005)

Porous carbons are widely used as industrial adsorbents because of the hydrophobic nature of their surfaces, high surface area, large pore volumes, chemical inertness, good mechanical stability, and good thermal stability. There has been a growing interest in new applications of porous carbons because of their ability to interact with molecules not only at their surfaces but also in the bulk of the material. The present review is about the synthesis of porous carbon by using templates. Special emphasis is placed on the type of templating agent and organic materials that are used. The details of the methods employed for this purpose and the results are introduced. By changing the template and organic precursor, one can synthesize porous carbons with different properties. Future studies need to be conducted on their controlled synthesis.
From Thia- to Selenadiazoles: Changing Interaction Priority (2013)

The synthesis, optical, and electrochemical properties as well as solid-state structures of a series of alkynylated, benzannulated selenadiazoles are reported. This set of compounds is compared to the lighter homologue series, the thiadiazoles. The selenadiazoles show head-to-head dimerization in the solid state, while packing of the thiadiazoles was dominated by the steric bulk of the side groups. The Se-N interaction is a supramolecular motif that should drive the effective self-assembly and modulate charge transport when these compounds are used as thin films in devices.

17beta-estradiol induced vitellogenesis is inhibited by cortisol at the post-transcriptional level in Arctic char (Salvelinus alpinus). (2004)

This study was performed to investigate stress effects on the synthesis of egg yolk precursor, vitellogenin (Vtg) in Arctic char (Salvelinus alpinus). In particular the effect of cortisol (F) was determined since this stress hormone has been suggested to interfere with vitellogenesis and is upregulated during sexual maturation in teleosts. Arctic char Vtg was purified and polyclonal antibodies were produced in order to develop tools to study regulation of vitellogenesis. The Vtg antibodies were used to develop an enzyme-linked immunosorbent assay. The corresponding Vtg cDNA was cloned from a hepatic cDNA library in order to obtain DNA probes to measure Vtg mRNA expression. Analysis of plasma from juvenile Arctic char, of both sexes, exposed to different steroids showed that production of Vtg was induced in a dose dependent fashion by 17beta-estradiol (E2), estrone and estriol. Apart from estrogens a high dose of F also upregulated Vtg. In addition, F, progesterone (P) and tamoxifen were tested to determine these compounds ability to modulate E2 induced Vtg synthesis at both the mRNA and protein level. Tamoxifen was found to inhibit E2 induced Vtg mRNA and protein upregulation. P did not alter the Vtg induction while F reduced the Vtg protein levels without affecting the Vtg mRNA levels. Furthermore the inhibition of Vtg protein was found to be dose dependent. Thus, the inhibitory effect of F on Vtg appears to be mediated at the post-transcriptional level.
Geo-tagged mobile photo sharing in collaborative emergency management (2011)

Establishing and maintaining communication between decision makers, professional responders and general public is vital in many emergency planning and rescue situations. In this paper we present our research on using first-hand information collected by mobile users to increase the flexibility and richness in collaborative emergency management. We propose our design to support direct positioning, quick assessment, and rich communication by leveraging mobile uploaded geo-tagged photos as shared media.
Micromirror based optical phased array for wide-angle beamsteering (2017)

Optical phased array (OPA) is a key enabling element for solid state LIDAR (light detection and ranging). In this paper, we demonstrate a novel MEMS micromirror array OPA. Vertical combdrive actuators are integrated underneath the mirrors to achieve a small pitch (2.4μm) and a large field of view (22° at 905nm wavelength and 40° at 1550nm). The OPA has 2μs response time, and 10V actuation voltage.
Novel Conjugation of Tumor‐Necrosis‐Factor‐Related Apoptosis‐Inducing Ligand (TRAIL) with Monomethyl Auristatin E for Efficient Antitumor Drug Delivery (2013)

Monomethyl auristatin E (MMAE) is conjugated with TNF-related apoptosis-inducing ligand (TRAIL) via a linker that is stable in extracellular fluid, while it is cleaved by cathepsin once the conjugate has entered a tumor cell, thus activating the antimitotic mechanism of MMAE. The TRAIL-MMAE conjugate is a conceptually viable therapeutic strategy with improved in vitro antitumor activity, cell circle arrest and specific accumulation in tumor to treat TRAIL-resistant tumors.
IL-13-Induced Chemokine Responses in the Lung: Role of CCR2 in the Pathogenesis of IL-13-Induced Inflammation and Remodeling (2002)

IL-13 stimulates inflammatory and remodeling responses and contributes to the pathogenesis of human airways disorders. To further understand the cellular and molecular events that mediate these responses, we characterized the effects of IL-13 on monocyte chemotactic proteins (MCPs) and compared the tissue effects of transgenic IL-13 in mice with wild-type (+/+) and null (-/-) CCR2 loci. Transgenic IL-13 was a potent stimulator of MCP-1, -2, -3, and -5. This stimulation was not specific for MCPs because macrophage-inflammatory protein (MIP)-1alpha, MIP-1beta, MIP-2, MIP-3alpha, thymus- and activation-regulated chemokine, thymus-expressed chemokine, eotaxin, eotaxin 2, macrophage-derived chemokines, and C10 were also induced. The ability of IL-13 to increase lung size, alveolar size, and lung compliance, to stimulate pulmonary inflammation, hyaluronic acid accumulation, and tissue fibrosis, and to cause respiratory failure and death were markedly decreased, whereas mucus metaplasia was not altered in CCR2(-/-) mice. CCR2 deficiency did not decrease the basal or IL-13-stimulated expression of target matrix metalloproteinases or cathepsins but did increase the levels of mRNA encoding alpha1-antitrypsin, tissue inhibitor of metalloproteinase-1, -2, and -4, and secretory leukocyte proteinase inhibitor. In addition, the levels of bioactive and total TGF-beta(1) were decreased in lavage fluids from IL-13 transgenic mice with -/- CCR2 loci. These studies demonstrate that IL-13 is a potent stimulator of MCPs and other CC chemokines and document the importance of MCP-CCR2 signaling in the pathogenesis of the IL-13-induced pulmonary phenotype.
Thermal effects in Cr/sup 2+/:ZnSe thin disk lasers (2005)

We report the modeling and experimental characterization of thermal lensing in Cr/sup 2+/:ZnSe face cooled laser disks using the phase shift interferometry technique. The thermal lens powers of the 1 mm and 0.5 mm thick disks were strong (23 and 7 diopters at 8 W pumping). The thermal lens power scaled with disk thickness and pump power, and temperatures were reached in the disks such that nonradiative relaxation was significant. Laser output greater than 4 W average power was achieved using face cooled thin disks of Cr/sup 2+/:ZnSe.
Evaluation of the use of reciprocating engines in compressed air energy storage plants (1978)

The application of reciprocating engines to compressed air energy storage (CAES) plants is presented. The expected advantages compared to plants using turbines and compressors are reduced reservoir size and cost, reduced compression energy, and increased overall plant efficiency. The performance of possible engine and plant configurations is presented. One configuration uses a reversible, reciprocating expander/compressor engine. Power generation results from engine operation as an internal-combustion expander; compression is accomplished using the same engine operating as a reciprocating compressor. Another possible configuration results when an internal-combustion engine is used as a high-pressure expander and a gas turbine is used as a low-pressure expander. Compression is accomplished using either separate turbocompressors or operating the high-pressure expander as a reversible-reciprocating compressor in series with a low-pressure turbocompressor. Capital and operating costs of plants using reciprocating engines are estimated and compared with that of turbine-based CAES plant designs. It is shown that using reciprocating engines can reduce capital and operating costs by about 11 and 8%, respectively, compared to a plant using available turbomachinery.
Effects in man of single and combined oral doses of reserpine, iproniazid, and <i>D</i>‐lysergic acid diethylamide (1960)

The use of d ‐lysergic acid diethylamide, LSD, as a reference standard for the evaluation of psychopathologic symptoms was tested. A group of healthy male volunteers took weekly doses of LSD in order to become familiar with the temporary mental changes induced by the drug. The subjects were able to identify three dose levels of LSD and to differentiate LSD from placebo and other drugs. A standard curve of the responses to LSD could be constructed for these subjects. A combination of reserpine plus iproniazid was found not to produce LSD‐like psychopathologic symptoms. The addition of reserpine and iproniazid to LSD did not change the degree or intensity of LSD‐induced psychopathologic symptoms in man.

Exploring the positive and negative implications of facial feedback. (2012)

The facial feedback effect (e.g., Strack et al., 1988) is explored in three experiments. It was found that when someone lowers their eyebrows, following instructions, their mood becomes more negative. If, however, they are instructed to raise their eyebrows they become more surprised by facts. Finally, if people are instructed to wrinkle their noses, then odors are evaluated as more unpleasant. While providing further diverse evidence for facial feedback, the experiments are also considered in the context of facial muscular paralysis induced as part of cosmetic treatments using botulinum toxin. The research presented here supports the previously suggested idea that such treatments could reduce depression, but other possible psychological impacts of such treatments are considered.
Microangiopathic Haemolytic Anaemia: Mechanisms of Red‐Cell Fragmentation: <i>in Vitro</i> Studies (1968)

S ummary . Several of the disease states in which red‐cell fragments appear in the peripheral blood have features suggestive of intravascular coagulation with fibrin deposition in vessels. As this process might be a cause of red‐cell fragmentation the interaction of rapidly moving red cells with fibrin strands was investigated. Red cells arrested on fibrin strands while moving through a loose fibrin clot at the velocity of arterial blood flow were bent over the strands by the force of blood flow and eventually fragmented. The shape of the fragments which resulted depended upon the position and plane in which the red cells were arrested, the point at which the membrane ruptured, the distribution of haemoglobin and membrane between the resulting fragments and finally on whether or not crenation of the fragments supervened. Systems in which red cells perfused artificial ‘clots’ of glass fibre and nylon also caused the red cells to fragment. The fragmentation process seems to depend, therefore, on a rapid blood flow and the arrest of individual red cells by any obstruction of small dimensions, e. g. by strands or spikes less than I p in diameter. It was concluded that these conditions were most likely to obtain in vivo as the result of intravascular deposits of fibrin in the lumen of small arterioles.
<title>Performance of photonic switching systems based on electro-optic volume holographic diffraction gratings</title> (2000)

We report on free-space photonic switches that are based on switched volume holographic diffraction grating for RF and telecommunications applications. For example, a cascade of n independently controlled electro-optic (EO) gratings can be configured in a binary tree structure to route a free-space optical carrier to on of 2<SUP>n</SUP> possible output channels. These gratings are comprised of liquid crystal composite materials, which exhibit low loss, high speed, and high switching contrast. Thus, this switching technology enables the construction of compact photonic switching systems with the potential for low insertion loss and low crosstalk. In this paper we describe grating based systems that are fanout capable, due to the inherent analog nature of the switched grating materials. Finally, we present the performance characteristics of the monolithic photonic switching systems constructed from arrays of switched gratings.
Policy-Based Agents for Virtual Machine Migration in Cloud Data Centers (2013)

Cloud data centers are networked server farms commonly composed of heterogeneous servers with a wide variety of computing capacities. Virtualization technology, in Cloud data centers, has improved server utilization and server consolidation. However, virtual machines may require unbalanced levels of computing resources (e.g., a virtual machine running a compute-intensive application with low memory requirements) causing resource usage imbalances within physical servers. In this paper, an agent-based distributed approach capable of balancing different types of workloads (e.g., memory workload) by using virtual machine live migration is proposed. Agents acting as server managers are equipped with 1) a collaborative workload balancing protocol, and 2) a set of workload balancing policies (e.g., resource usage migration thresholds and virtual machine migration heuristics) to simultaneously consider both server heterogeneity and virtual machine heterogeneity. The experimental results show that policy-based workload balancing is effectively achieved despite dealing with server heterogeneity and heterogeneous workloads.
A practical postprocessing technique for real-time block-based coding system (1998)

A noniterative postprocessing method is proposed to restore the images encoded with block-based compression standards such as Joint Photographic Experts Group (JPEG). This method classifies small local boundary regions according to their intensity distribution and then selects appropriate linear predictors to estimate the corresponding boundary pixels in the regions. This approach is easy to implement and we found in our simulations that its restoration performance was very respectable compared with the reported postprocessing methods.
Vague Query Formulation by Design. (2012)

When users search for information in domains they are not familiar with, they usually struggle to formulate an adequate (textual) query. Often users end up with repeating re-formulations and query refinements without necessarily achieving their actual goals. In this paper we propose a user interface that is capable to offer users flexible and ergonomic interaction elements to formulate even complex queries in a simple and direct way. We call this principle vague query formulation by design. By this formulation we like to point out its design-driven origin. The proposed radial user interface supports phrasing and interactive visual refinement of vague queries to search and explore large document sets. The main idea is to provide an integrated view of queries and related results, where both queries and results can be interactively manipulated and influence each other. Changes will be immediately visualized. The concept was implemented on a tablet computer and the usability was stepwise evaluated during a formative and a summative evaluation process. The results reveal high usability ratings, even if the concept was completely unknown to our test users.
A Grain of Salt for the WMT Manual Evaluation (2011)

The Workshop on Statistical Machine Translation (WMT) has become one of ACL's flagship workshops, held annually since 2006. In addition to soliciting papers from the research community, WMT also features a shared translation task for evaluating MT systems. This shared task is notable for having manual evaluation as its cornerstone. The Workshop's overview paper, playing a descriptive and administrative role, reports the main results of the evaluation without delving deep into analyzing those results. The aim of this paper is to investigate and explain some interesting idiosyncrasies in the reported results, which only become apparent when performing a more thorough analysis of the collected annotations. Our analysis sheds some light on how the reported results should (and should not) be interpreted, and also gives rise to some helpful recommendation for the organizers of WMT.
A fully programmable CMOS block matrix transform imager architecture (2004)

In this paper, we introduce our CMOS block matrix transform imager architecture (MATIA). This imager is capable of performing programmable matrix operations on an image. The imager architecture is both modular and programmable. The pixel used in this architecture performs matrix multiplication while maintaining a high fill-factor (46%), comparable to active pixel sensors. Floating gates are used to store the arbitrary matrix coefficients on-chip. The chip operates in the subthreshold domain and thus has low power consumption (0.23 mW).
Compressive Receiver Using a CRLH-Based Dispersive Delay Line for Analog Signal Processing (2009)

A compressive receiver (CR) is presented utilizing a composite right/left-handed (CRLH) dispersive delay line (DDL) for analog signal processing applications. The CRLH DDL offers advantages such as arbitrary frequency of operation and wide bandwidth, filling a gap with competing DDL technologies. The presented CR system utilizes an impulse-driven CRLH DDL and mixer inversion for chirp generation required for real-time signal processing. At high frequencies, this eliminates frequency ramp generators. The CR is employed as a frequency discriminator and a tunable delay line with dispersion compensation. The simulation and experimental results fully validate the presented systems as proof-of-concept for high-frequency applications such as real-time Fourier transformers and signal analyzers.
