Pancreatic Regenerating Gene I and Acinar Cell Differentiation (2009)

These data demonstrate that in acinar cells, reg I overexpression is linked to acinar cell differentiation, whereas inhibition of reg I leads to beta cell and possibly ductal phenotype. Reg I expression in acinar cells is important in maintaining pancreatic cell lineage, and when decreased, cells can dedifferentiate and move toward becoming other pancreatic cells.
N‐(4‐(4‐(2‐Halogenophenyl)piperazin‐1‐yl)butyl) Substituted Cinnamoyl Amide Derivatives as Dopamine D2 and D3 Receptor Ligands (2007)

A series of eight substituted N-(4-(4-(2-halogenophenyl)piperazin-1-yl)butyl)-3-phenylacryl amide derivatives have been synthesized and screened for binding affinities at dopamine hD(2) and hD(3) receptors. All compounds have shown high to remarkable receptor affinities and some have led to distinct selectivity for D(3) receptors. Highest D(3)-receptor affinity has been observed for 3-(4-aminophenyl)-N-(4-(4-(2-fluorophenyl)piperazin-1-yl)butyl)acryl amide (hD(3) K(i) 0.9 nM; hD(2) K(i) 17.4 nM). Selectivity ratio has been best for 3-(4-chlorophenyl)-N-(4-(4-(2-fluorophenyl)piperazin-1-yl)butyl)acryl amide with a 56-fold preference for hD(3) versus hD(2). A functional activity test has been performed by a mitogenesis test for N-(4-(4-(2-fluorophenyl)piperazin-1-yl)butyl)-3,3-diphenylacryl amide, which, surprisingly, has shown full agonist properties.
Spot-Size Dependence of Laser Induced Retinal-Damage Threshold (1999)

The dependence of retinal damage threshold on laser spot size was examined for two pulsewidth regimes; nanosecond-duration Q-switched pulses from a doubled Nd:YAG laser and microsecond-duration pulses from a flashlamp-pumped dye laser. Threshold determinations were conducted for nominal retinal image sizes ranging from 1.5 mrad to 100 mrad of visual field, corresponding to image diameters of ~22 μm to 1.4 mm on the primate retina. In addition, baseline collimated-beam damage thresholds were determined for comparison to the extended source data. Together, this set of retinal damage thresholds reveals the functional dependence of threshold on spot size. The threshold dose was found to vary with the area of the image for larger image sizes. The results are compared to previously published extended source damage thresholds and to the ANSI Z136.1 laser safety standard maximum permissible exposure levels for diffuse reflections.
Inverse Transport Networks (2018)

We introduce inverse transport networks as a learning architecture for inverse rendering problems where, given input image measurements, we seek to infer physical scene parameters such as shape, material, and illumination. During training, these networks are evaluated not only in terms of how close they can predict groundtruth parameters, but also in terms of whether the parameters they produce can be used, together with physically-accurate graphics renderers, to reproduce the input image measurements. To en- able training of inverse transport networks using stochastic gradient descent, we additionally create a general-purpose, physically-accurate differentiable renderer, which can be used to estimate derivatives of images with respect to arbitrary physical scene parameters. Our experiments demonstrate that inverse transport networks can be trained efficiently using differentiable rendering, and that they generalize to scenes with completely unseen geometry and illumination better than networks trained without appearance- matching regularization.
Fabrication of thick silicon dioxide layers using DRIE, oxidation and trench refill (2003)

This paper reports a new method of fabricating very thick (10-100 /spl mu/m) silicon dioxide layers without the need for very long deposition or oxidation. DRIE is used to create high aspect ratio trenches and silicon pillars, which are then oxidized and/or refilled with LPCVD oxide to create layers as thick as the DRIE allows. Stiffeners are used to provide support for the pillars during oxidation. Thermal tests show that such thick silicon dioxide diaphragms can effectively thermally isolate heated structures from neighboring structures within a distance of hundreds of microns. The thermal conductivity of the thick SiO/sub 2/ is measured to be /spl sim/1.1 W/(m/spl middot/K). Such SiO/sub 2/ diaphragms of thickness 50-60 /spl mu/m can sustain an extrinsic shear stress up to 3-5 MPa.
Activation and recruitment of brown adipose tissue as anti-obesity regimens in humans (2014)

Brown adipose tissue (BAT) is the site of sympathetically activated adaptive thermogenesis during cold exposure and after hyperphagia, thereby controlling whole-body energy expenditure (EE) and body fat. BAT thermogenesis is primarily dependent on the energy-dissipating activity of uncoupling protein 1 (UCP1). There are two types of UCP1-expressing adipocyte, classical brown and beige/brite adipocytes. Recent radionuclide studies have demonstrated the existence of metabolically active BAT composed of mainly beige/brite adipocytes in adult humans. Human BAT is activated by acute cold exposure, being positively correlated to cold-induced increases in EE. The inverse relationship between the BAT activity and body fatness suggests that BAT, because of its energy-dissipating activity, is protective against body fat accumulation. In fact, either repeated cold exposure or daily ingestion of some food ingredients acting on transient receptor potential channels recruited BAT in association with increased EE and decreased body fat. Moreover, possible contribution of BAT to glucose tolerance has been suggested. In addition to the sympathetic nervous system, some endocrine factors also have potential for activation/recruitment of BAT. Thus, BAT is a promising therapeutic target for combating human obesity and related metabolic disorders.

Uniformity of accommodation across the visual field (2016)

We asked the question: Does accommodation change the eye's focusing power equally over the central visual field in emmetropic and myopic adult eyes? To answer this question we modified our laboratory scanning wavefront aberrometer to rapidly measure ocular refractive state over the central 30° diameter of visual field as a function of foveal accommodative demand. On average, ocular refractive state changed uniformly over the central visual field as the eye accommodated up to 6 D. Visual field maps of accommodative error (relative to a spherical target surface of constant vergence) reveal subtle patterns of deviation on the order of ± 0.5 D that are unique to the individual and relatively invariant to changes in accommodative state. Population mean maps for accommodative error are remarkably uniform across the central visual field, indicating the retina of the hypothetical "average eye" is conjugate to a sphere of constant target vergence for all states of accommodation, even though individual eyes might deviate from the mean due to random variations. No systematic difference between emmetropic and myopic eyes was evident. Since accuracy of accommodation across the central visual field is similar to that measured in the fovea, loss of image quality due to accommodative errors, which potentially drives myopia and may affect many aspects of visual function, will be similar across the central retina.
Correlation between recombinase activating gene 1 ubiquitin ligase activity and V(D)J recombination (2009)

The really interesting new gene (RING) finger ubiquitin ligase domain of the recombinase activating gene 1 (RAG1) V(D)J recombinase protein adopts a standard cross-brace architecture but co-ordinates three zinc ions as opposed to the canonical two. We demonstrated previously that disruption of the conserved zinc co-ordination sites resulted in loss of structural integrity and ubiquitin ligase (E3) activity and interfered with the ability of full-length RAG1 to support recombination. Here we present evidence that amino acids surrounding the third, non-canonical site also contribute to functional interaction with the ubiquitin conjugating (E2) enzyme CDC34, while certain residues on the RING domain's surface important for interaction between other E2-E3 pairs are less critical to the functional RAG1-CDC34 interaction in this assay. Partial reduction of ubiquitin ligase activity was significantly correlated with reduction in the ability of RAG1 to support recombination of extra-chromosomal substrates (r = 0.805, P = 0.009). While poly-ubiquitin chains could be generated, RAG1 did not promote rapid chain extension following mono-ubiquitylation of substrate, regardless of the E2 enzyme used. No single ubiquitin lysine mutant disrupted the ability of CDC34 to form ubiquitin chains on RAG1, and mass spectrometric analysis of the poly-ubiquitylated products indicated ubiquitin chain linkages through lysines 48 and 11. These data suggest that RAG1 promotes a mono-ubiquitylation reaction that is required for optimal levels of V(D)J recombination.
Apollo Lunar Module Engine Exhaust Products (1969)

Organic combustion products generated by the lunar module descent engine, which burns a 1:1 mixture of unsymmetrical dimethylhydrazine fuel and nitrogen tetroxide oxidizer, have been analyzed. The major gaseous combustion products found were ammonia, water, carbon monoxide, nitrous oxide, oxygen, carbon dioxide, and nitric oxide. The minor products were acetylene, hydrogen cyanide, ethylene, formaldehyde, propadiene, ketene, cyanous acid, hydrazoic acid, various methylamines, acetaldehyde, methyl nitrite, formic acid, nitrous acid, butadiyne, nitrilohydrazines, nitromethane, and nitrosohydrazines with other oxidized derivatives of unsymmetrical dimethylhydrazine and hydrazine. The ion intensities of the various species in all mass spectra were estimated as the following concentrations: the gases (NH(3), H(2)O, CO, NO, O(2), CO(2), and NO(2)), 87.7 percent; compounds of C, H, and O, 6.0 percent; and compounds of C, H, and N (with traces of O), 5.8 percent.
Modelling End-of-Session Actions in Educational Systems (2019)

In this paper we consider the problem of modelling when students end their session in an online mathematics educational system. Being able to model this accurately will help us optimize the way content is presented and consumed. This is done by modelling the probability of an action being the last in a session, which we denote as the End-of-Session probability. We use log data from a system where students can learn mathematics through various kinds of learning materials, as well as multiple types of exercises, such that a student session can consist of many different activities. We model the End-of-Session probability by a deep recurrent neural network in order to utilize the long term temporal aspect, which we experimentally show is central for this task. Using a large scale dataset of more than 70 million student actions, we obtain an AUC of 0.81 on an unseen collection of students. Through a detailed error analysis, we observe that our model is robust across different session structures and across varying session lengths.
The Anterolateral Thigh Flap is Highly Effective for Reconstruction of Complex Lower Extremity Trauma (2007)

The ALT flap is a useful tool for trauma reconstruction in lower extremity salvage. We have shown that the ALT flap can be performed successfully in the traumatically injured patient even when harvested from the ipsilateral lower extremity.
Solvent segregation and capillary evaporation at a superhydrophobic surface investigated by confocal Raman microscopy and force measurements (2010)

Wetting of water, a 1 : 1 water/ethanol mixture and an aqueous dodecylbenzene sulfonic acid surfactant solution on hydrophobic and superhydrophobic surfaces were studied using confocal Raman microscopy. The superhydrophobic surfaces were prepared by immersion of a glass substrate in a silica particle/fluoropolymer formulation followed by silanization. Preparation of hydrophobic surfaces was done in the same way with the exception that the silica particles were excluded from the formulation. The hydrophobic and superhydrophobic surfaces were characterized with respect to surface roughness using AFM, and by contact angle measurements using different liquids. Confocal Raman microscopy measurements in a 1 : 1 water/ethanol mixture showed an enrichment of ethanol close to the superhydrophobic surface, which could not be observed for the hydrophobic surface. Unexpectedly, the Raman spectrum of a pure water film in close proximity to the superhydrophobic surface displayed some differences compared to that of bulk water and indicated a stronger hydrogen-bonding close to the superhydrophobic surface. Evidence for capillary evaporation next to the superhydrophobic surface was also found, and this results in very long-range capillary attraction between one superhydrophobic surface and a hydrophobic colloidal probe as shown by AFM colloidal probe force measurements. Addition of a surfactant or ethanol suppresses capillary evaporation.

Bluetooth digital still camera (2003)

The Bluetooth specifications currently include many application profiles that define the requirements for some usage cases. In this paper the attention is focused on the 'Basic Imaging Profile' BIP. The BIP could add important features to classic Digital Still Cameras, such as the possibility to send images to a Bluetooth Printer, or to send the image on Internet with a Bluetooth cellular phone.

The set-up is described, and some informal observations on the nature of the bilingual dialogues reported.
Variability in soy flour composition (2003)

Abstract Soy flour is commonly used as a protein source in industrial fermentations. As an essentially natural product, the composition of soy flour can vary from year to year as a result of changes in growing conditions. The composition of soy flour from a single manufacturing plant was determined over an 8‐yr period. Protein concentration varied from 51.2% in the 1997 crop to 53.2% in the 1998 crop, but overal amino acid composition was relatively constant. The concentrations of valine, isoleucine, tyrosine, and alanine showed significant variation between years. Crude fat levels were steady, but the fat by acid hydrolysis (FAH) levels varied, suggesting changes in the level of phospholipids. The difference between the crude fat and FAH analyses (a proxy for phospholipids) had a strong positive correlation ( P &lt;0.001) with the total phosphorus concentration, consistent with this interpretation. FA distribution varied year to year with linoleic acid providing the most dramatic effect. Fe and P concentrations showed significant variation, but Al, Ca, Cu, K, Mg, Mn, Mo, Ni, and Zn did not vary significantly. Although P concentration had a significant correlation with proxy phospholipid levels, there was not a significant correlation between P concentration and phytic acid concentrations
Gamma-gamma prime-gamma double prime dual-superlattice superalloys (2017)

Improving the efficiency of gas turbine engines requires the development of new materials capable of operating at higher temperatures and stresses. Here, we report on a new polycrystalline nickel-base superalloy that has exceptional strength and thermal stability. These properties have been achieved through a four-element composition that can form both gamma prime and gamma double prime precipitates in comparable volume fractions, creating an unusual dual-superlattice microstructure. Alloying studies have shown that further property improvements can be achieved, and that with development such alloys may be suitable for future engine applications.
Validation of the IPSET score for thrombosis in patients with prefibrotic myelofibrosis (2020)

Pre-fibrotic myelofibrosis (pre-PMF) and essential thrombocythemia (ET) are characterized by similarly increased rate of thrombotic events, but no study specifically analyzed risk factors for thrombosis in pre-PMF. In a multicenter cohort of 382 pre-PMF patients collected in this study, the rate of arterial and venous thrombosis after diagnosis was 1.0 and 0.95% patients/year. Factors significantly associated with arterial thrombosis were age, leukocytosis, generic cardiovascular risk factors, JAK2V617F and high molecular risk mutations, while only history of previous thrombosis, particularly prior venous thrombosis, was predictive of venous events. The risk of total thromboses was accurately predicted by the the international prognostic score for thrombosis in essential thrombocythemia (IPSET) score, originally developed for ET, and corresponded to 0.67, 2.05, and 2.95% patients/year in the low-, intermediate-, and high-risk categories. IPSET was superior to both the conventional 2-tiered score and the revised IPSET in this cohort of pre-PMF patients. We conclude that IPSET score can be conveniently used for thrombosis risk stratification in patients with pre-PMF and might represent the basis for individualized management aimed at reducing the increased risk of major cardiovascular events. Further refinement of the IPSET score in pre-PMF might be pursued by additional, prospective studies evaluating the inclusion of leukocytosis and/or adverse mutational profile as novel variables.
3D Inversion of Large-scale Time Domain Electromagnetic Data (2013)

Airborne time-domain electromagnetic (EM) surveys are effective tools for mineral exploration, geologic mapping and environmental applications. 3D inversion of airborne electromagnetic data is a challenging computational problem. The size of the surveys and the spatial resolution required to adequately discretize the transmitters and receivers results in very large meshes. Solving the forward problem repeatedly on such a mesh can quickly become impractical. Fortunately, using a single mesh for both the forward and inverse problem for all of the transmitters is not necessary. The forward problem for a single source or a small group of sources can be solved on different meshes, each of which need only be locally refined with fine cells close to the selected transmitters and receivers. Away from the selected transmitters and receivers, the mesh can be coarsened. The forward problem can then be broken into a number of highly parallel problems. Each forward modelling mesh is optimized specific to the selected transmitters and receivers and has far fewer cells than the fine inversion mesh. In this abstract, we present an implementation of this idea using a finite volume discretization on OcTree meshes. We demonstrate our approach on a VTEM data set over a porphyry deposit in Canada.
Surface Modification of Denture to Provide Contamination-Free Ability by Using Silane Coupling Agent Containing Fluorocarbon Chain (1993)

Abstract Silane coupling agent containing fluorocarbon chain, (1H,1H,2H,2H-henicosafluorododecyl)trimethoxysilane, was applied for the surface modification of some dental materials. The contact angles of water and oleic acid on the modified material surfaces were increased. The modified denture teeth worn in an oral cavity displayed a long-range stain-protecting ability.

Scalable security for large, high performance storage systems (2006)

New designs for petabyte-scale storage systems are now capable of transferring hundreds of gigabytes of data per second, but lack strong security. We propose a scalable and efficient protocol for security in high performance, object-based storage systems that reduces protocol overhead and eliminates bottlenecks, thus increasing performance without sacrificing security primitives. Our protocol enforces security using cryptographically secure capabilities, with three novel features that make them ideal for high performance workloads: a scheme for managing coarse grained capabilities, methods for describing client and file groups, and strict security control through capability lifetime extensions. By reducing the number of unique capabilities that must be generated, metadata server load is reduced. Combining and caching client verifications reduces client latencies and workload because metadata and data requests are more frequently serviced by cached capabilities. Strict access control is handled quickly and efficiently through short-lived capabilities and lifetime extensions.We have implemented a prototype of our security protocol and evaluated its performance and scalability using a high performance file system workload. Our numbers demonstrate the ability of our protocol to drastically reduce client security latency to nearly zero. Additionally, our approach improves MDS performance considerably, serving over 99% of all file access requests with cached capabilities. OSD scalability is greatly improved; our solution requires 95 times fewer capability verifications than previous solutions.
