The chemokine receptor CCR1 is strongly up‐regulated after skin injury but dispensable for wound healing (2004)

To identify key regulators of cutaneous wound repair, we analyzed a subtractive cDNA library of normal and wounded mouse skin. One of the identified genes encodes the chemokine receptor CCR1, which binds several chemokines present at the wound site. Expression of CCR1 was barely detectable in nonwounded skin, but strong up-regulation was observed after injury to wild-type mice. Most important, the healing abnormalities observed in glucocorticoid-treated mice and activin-overexpressing transgenic mice correlated with an altered expression of CCR1. CCR1-positive cells were identified as macrophages and neutrophils within the wounded area. To determine the importance of CCR1 for wound repair, we analyzed this process in CCR1 knockout mice. Surprisingly, no alterations in either wound closure, wound appearance, wound bursting strength, granulation tissue formation, or re-epithelialization were observed. In addition, the inflammatory response was unaltered in CCR1-deficient mice and the expression of several chemokines, chemokine receptors, and other important regulators of wound repair were normal in these animals. These results show that CCR1 is dispensable for wound healing, most likely due to redundancy in chemokine/chemokine receptor signaling.
Positive family history of coronary atherosclerosis and serum triglycerides may predict repeated coronary artery bypass surgery (2005)

According to this study, positive family history for coronary atherosclerosis at the presence of high serum triglyceride level is significantly predicting the need for future redo CABG as compared with age, gender and operation time matched controls of CABG.
A Randomized, Controlled Study to Evaluate the Role of an In-Home Asthma Disease Management Program Provided by Respiratory Therapists in Improving Outcomes and Reducing the Cost of Care (2009)

An in-home asthma management program can be effectively delivered by respiratory therapists and may reduce hospitalizations, in-patient days, cost and improve measures of HRQOL and PS in a population prone to asthma exacerbation.
Near-field magneto-photoluminescence of GaAs/AlGaAs/InP/GaInP2 quantum well-quantum dot structures (2021)

Abstract This work presents the results of the growth, structural characterization and magneto-photoluminescence spectroscopy measurements of GaAs/AlGaAs/InP/GaInP 2 quantum well-quantum dot structures. We demonstrate that GaAs/AlGaAs QDs in these structures are formed above InP/GaInP 2 QDs. This allows us to measure the internal magnetic field in the InP/GaInP 2 QD by monitoring the Zeeman splitting of the excitonic transition in the GaAs/AlGaAs QD.
Enantioselective α‐Arylation of Cyclic Ketones Catalyzed by a Combination of an Unmodified Cinchona Alkaloid and a Palladium Complex (2012)

Abstract A palladium/ Cinchona alkaloid‐catalyzed α‐arylation between cyclic ketones and aryl halides under phosphine‐free conditions is presented. The use of a simple, unmodified Cinchona alkaloid results in high levels of activity and selectivity with up to 93% ee . These enantioinduction levels are comparable or even higher than the ones reported using palladium/BINAP complexes. To the best of our knowledge, this represents the first use of unmodified Cinchona alkaloids as ligands/catalysts in asymmetric transition metal complex‐catalyzed cross‐coupling reactions.
Building peer-to-peer systems with chord, a distributed lookup service (2005)

We argue that the core problem facing peer-to-peer Systems is locating documents in a decentralized network and propose Chord, a distributed lookup primitive. Chord provides an efficient method of locating documents while placing few constraints on the applications that use it. As proof that Chord's functionality is useful in the development of peer-to-peer applications, we outline the implementation of a peer-to-peer file sharing system based on Chord.

Application of converted-wave 3D/3-C data for fracture detection in a deep tight-gas reservoir (2009)

The deep-gas reservoirs of China's western Sichuan Basin are in Members 2 and 4 of the Upper Triassic Xujiahe Formation. These reservoirs contain mid- to large-sized gas fields like Xinchang, Hexingchang, Qiongxi, Zhongba, and Bajiaochang. The favorable geological conditions for creating these fields include abundant source rock, well-developed reservoir rock, good preservation conditions, and structural traps.
Deviations of CZT detector response caused by isolated Te precipitates (2006)

We present new results from our studies of defects in current single-crystal CdZnTe material. Our previous measurements, carried out on thin (~1 mm) and long (>12 mm) CZT detectors, indicated that small (1-20 &#956;m) Te inclusions can significantly degrade the device's energy resolution and detection efficiency. We are conducting detailed studies of the effects of Te inclusions by employing different characterization techniques with better spatial resolution, such as quantitative fluorescence mapping, X-ray micro-diffraction, and TEM. Also, IR microscopy and gamma-mapping with pulse-shape analysis with higher spatial resolution generated more accurate results in the areas surrounding the micro-defects (Te inclusions). Our results reveal how the performance of CdZnTe detectors is influenced by Te inclusions, such as their spatial distribution, concentration, and size. We also discuss a model of charge transport through areas populated with Te inclusions.
<title>Uniform LED illuminator for miniature displays</title> (1998)

The Total Internally Reflecting (TIR) lens is a faceted structure composed of prismatic elements that collect a source's light over a much larger angular range than a conventional Fresnel lens. It has been successfully applied to the efficient collimation of light from incandescent and fluorescent lamps, and from light-emitting diodes (LEDs). A novel LED-powered collimating backlight is presented here, for uniformly illuminating 0.25'-diagonal miniature liquid- crystal displays, which are a burgeoning market for pagers, cellular phones, digital cameras, camcorders, and virtual- reality displays. The backlight lens consists of a central dual-asphere refracting section and an outer TIR section, properly curved with a curved exit face.
Al-2.68 Mask (2021)

As increasingly smaller molecular materials and material structures are devised or developed for technological applications, the demands on the processes of lithography now routinely include feature sizes that are of the order of 10 nm. In reaching such a fine level of resolution, the methods of lithography have increased markedly in sophistication and brought into play 2terminology that is unfamiliar, on the one hand, to scientists tasked with the development of new lithographic materials or, on the other, to the engineers who design and operate the complex equipment that is required in modern-day processing. Publications produced by scientists need to be understood by engineers and vice versa, and these commonly arise from collaborative research that draws heavily on the terminology of two or more of the traditional disciplines. It is developments in polymer science and material science that lead progress in areas that cross traditional boundaries, such as microlithography. This document provides the exact definitions of a selection of unfamiliar terms that researchers and practitioners from different disciplines might encounter.
Dependence of Lattice Constant Deviation and Refractive Index on Proton Concentration in Proton-Exchanged Optical Waveguides on a Single Crystal of LiNbO3 (1992)

The lattice constant deviation and refractive index change of proton-exchanged optical waveguides fabricated on a single crystal of LiNbO 3 are discussed in relation to the proton concentration. The exchange rate x of Li + with H + has been determined by nuclear reaction analysis and the lattice constant deviation has been measured by means of the double crystal X-ray diffraction method. The value of x in the samples proton-exchanged with the benzoic acid/lithium benzoate melts is in the range of 0.55&lt; x &lt;0.75. After annealing in air, x decreases with increasing annealing time. The lattice constant deviation is proportional to x in the range of x &lt;0.55, while it is almost constant in the range of x &gt;0.55. The dependence of the refractive index change on x is very similar to that of the lattice constant deviation. Reasons for the refractive index change caused by proton exchange are discussed.
Crystal structure of the photosensing module from a red/far-red light-absorbing plant phytochrome (2014)

Many aspects of plant photomorphogenesis are controlled by the phytochrome (Phy) family of bilin-containing photoreceptors that detect red and far-red light by photointerconversion between a dark-adapted Pr state and a photoactivated Pfr state. Whereas 3D models of prokaryotic Phys are available, models of their plant counterparts have remained elusive. Here, we present the crystal structure of the photosensing module (PSM) from a seed plant Phy in the Pr state using the PhyB isoform from Arabidopsis thaliana. The PhyB PSM crystallized as a head-to-head dimer with strong structural homology to its bacterial relatives, including a 5(Z)syn, 10(Z)syn, 15(Z)anti configuration of the phytochromobilin chromophore buried within the cGMP phosphodiesterase/adenylyl cyclase/FhlA (GAF) domain, and a well-ordered hairpin protruding from the Phy-specific domain toward the bilin pocket. However, its Per/Arnt/Sim (PAS) domain, knot region, and helical spine show distinct structural differences potentially important to signaling. Included is an elongated helical spine, an extended β-sheet connecting the GAF domain and hairpin stem, and unique interactions between the region upstream of the PAS domain knot and the bilin A and B pyrrole rings. Comparisons of this structure with those from bacterial Phys combined with mutagenic studies support a toggle model for photoconversion that engages multiple features within the PSM to stabilize the Pr and Pfr end states after rotation of the D pyrrole ring. Taken together, this Arabidopsis PhyB structure should enable molecular insights into plant Phy signaling and provide an essential scaffold to redesign their activities for agricultural benefit and as optogenetic reagents.
Neutral thermospheric temperature from ion concentration measurements (1981)

An analysis and evaluation are presented of a technique for extracting information on neutral thermospheric temperature from satellite measurements of the relative abundances of H + and O + ions in the F region. Charge‐exchange equilibrium in the neighborhood of 320 km relates the observed altitude distribution of this ion concentration ratio directly to that of the associated neutral species and thus to the neutral temperature. The method has been applied to an extensive set of ion concentration data acquired with the Atmosphere Explorer C and D satellites, and evaluated through direct comparison of these ‘ion‐ratio’ temperatures with other concurrent in situ measurements. A comprehensive orbit‐by‐orbit comparison is presented with both ion temperature data and with calculations from the MSIS model. Select comparisons are also available with direct temperature measurements from the Nate instrument, and with temperatures derived from height distributions of observed neutral particle densities. Statistical analyses emphasize random and systematic differences between these several alternative types of temperature data. Sources and estimates of possible uncertainties unique with the ion‐ratio method are also discussed. Excellent agreement has been achieved between the ion‐ratio and the ion temperatures from the AE‐D satellite; the analysis is, however, unable to account for a small systematic difference between corresponding measurements from AE‐C. A random uncertainty of ∼5% must also be associated with neutral temperatures derived from the ion‐ratio method. Otherwise, a general consistency is demonstrated between the various forms of temperature data. All classes of measurements indicate that nighttime thermospheric temperatures are lower than predicted by the MSIS model.
Influence of deposition conditions on texture development and mechanical properties of TiN coatings (2009)

Abstract The influence of varying substrate temperature, N 2 partial pressure, ion energy, and ion-to-Ti flux ratio on the texture development and mechanical properties of TiN is investigated in detail. We show that during low substrate temperature (T s = 300 °C) reactive sputtering of TiN in a mixed Ar + N 2 discharge a change from 111- to 001-oriented growth occurs when increasing the ion-to-Ti ratio J i / J Ti above 2.5 while using a low ion energy E i of 30 eV. This texture change can be reversed to a 111-oriented growth by increasing the ion energy to 60 and 90 eV when using high ion-to-Ti ratios J i / J Ti of 2.5 and 9, without introducing strain. Thereby the hardness can be increased from ∼31 to 37 GPa with only minor changes in compressive stresses. Consequently, by defining the ion-to-Ti ratio and the ion energy during low substrate temperature reactive sputtering of TiN the texture development towards 111- or 001-oriented growth can be controlled. Based on previous studies and the texture development as a function of substrate temperature and N 2 -partial pressure, we propose that varying the ion-to-Ti ratio and the ion energy result in different N-terminated surfaces and hence different Ti-fluxes from 111- to 001-oriented grains and vice versa.
Toxicity of non-thermal dielectric barrier discharge plasma treatment of endothelial cells (2008)

Non-thermal dielectric barrier discharge plasma is now being widely developed for various medical applications such as skin sterilization, blood coagulation, induction of apoptosis in malignant tissues, and wound healing among others. In this paper we investigate the toxicity of non- thermal plasma treatment on endothelial cells, which line all blood contacting surfaces in the body. This research explores the effect of non-thermal plasma on the vasculature, which is affected during plasma treatment of many tissues and may be an important potential target for clinical plasma therapy.
A High-Speed and Low-Breakdown-Voltage Silicon Avalanche Photodetector (2014)

A silicon avalanche photodetector with a low breakdown voltage of -6.78 V is demonstrated by narrowing down the intrinsic layer width of interdigitated p-i-n junctions to ~ 150 nm. It reaches the physical limit of avalanche breakdown in which the performance degradation caused by the Zener tunneling process is negligible. Dark current at -4 V is measured, and a responsivity (gain) exceeding 1.424 A/W (110) at -6.75 V is obtained with an 850-nm laser illumination. The intrinsic bandwidth is determined to be 10 GHz, suggesting our device is applicable for a 10-Gb/s high-speed optical receiver application and beyond.
Energy level alignment at interfaces of organic semiconductor heterostructures (1998)

We have used ultraviolet photoelectron spectroscopy (UPS) to investigate the interfaces of two organic semiconductor heterostructures. UPS was used to determine the relative energies of the highest occupied molecular orbitals of the organic semiconductors, and to measure the interface dipoles at each interface. The two systems studied were the 4-4′-N,N′-dicarbazolyl-biphenyl(CBP)/tris(8-hydroxy-quinoline)aluminum (Alq3) interface, and the copper phthalocyanine (CuPc)/N,N′-diphenyl-N,N′-bis(1-naphthyl)-1,1′biphenyl-4,4″diamine (α-NPD) interface. The assumption of a common vacuum level was found to be valid, within experimental uncertainty, for both interfaces.
Studies of Cloud Characteristics Related to Jet Engine Ice Crystal Icing Utilizing Infrared Satellite Imagery (2015)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;The significant problem of engine power-loss and damage associated with ice crystal icing (ICI) was first formally recognized by the industry in a 2006 publication [&lt;span class="xref"&gt;1&lt;/span&gt;]. Engine events described by the study included: engine surge, stall, flameout, rollback, and compressor damage; which were triggered by the ingestion of ice crystals in high concentrations generated by deep, moist convection.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;Since 2003, when ICI engine events were first identified, Boeing has carefully analyzed event conditions documenting detailed pilot reports and compiling weather analyses into a database. The database provides valuable information to characterize environments associated with engine events. It provides boundary conditions, exposure times, and severity to researchers investigating the ICI phenomenon. Ultimately, this research will aid in the development of engine tests and ICI detection/avoidance devices or techniques.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;This paper first provides a detailed examination of the ICI engine event database from a statistical perspective. Environments sampled during the 2014 HAIC-HIWC field campaign, based in Darwin, Australia, are compared to the ICI engine database and it is shown that test flights fell within the expected range of conditions. A new, novel approach to track mesoscale motion of convectively generated ice is introduced. The Mesoscale convective Ice Following (MIF) model uses infrared satellite (IR) cloud top data in conjunction with vertical wind profiles in an attempt to improve upon the detection of high ice water content (HIWC) regions embedded with mesoscale convective systems (MCS). Finally, a preliminary assessment is made of MIF model results using in-situ ice concentration measurements for verification.&lt;/div&gt;&lt;/div&gt;
Prediction of Oxidation-Limited Lifetime of Stainless Steel Foils for Primary Surface Recuperators (2007)

Abstract Austenitic and ferritic stainless steels are susceptible to breakaway oxidation when exposed to oxidizing gases containing water vapor at elevated temperatures. The normally protective chromium oxide film is disrupted by rapidly-growing mixed oxide nodules. This phenomenon can result in significant damage to the metal substrate, particularly for thin foil sections. A model has been created to predict the onset of failure in air containing water vapor for several austenitic stainless steels, based on testing and analysis of a large number of laboratory specimens.

A vision system for daily assistive robots using character information in daily environments (2013)

This paper describes a vision system that is for using character information for robots working on daily environments. It is mainly composed of image-based recognition module that detects character candidates by taking particular note of closed contour in an image. In addition, to cope with tiny or distant characters, a camera system with mechanical gaze adjustment is collaborated with the image processing. By combining the detection result with OCR (Optical Character Reader), applications to daily assistance by an autonomous robot were introduced.

Microwave-excited ultrasound and thermoacoustic dual imaging (2017)

We designed a microwave-excited ultrasound (MUI) and thermoacoustic dual imaging system. Under the pulsed microwave excitation, the piezoelectric transducer used for thermoacoustic signal detection will also emit a highly directional ultrasonic beam based on the inverse piezoelectric effect. With this beam, the ultrasonic transmitter circuitry of the traditional ultrasound imaging (TUI) system can be replaced by a microwave source. In other words, TUI can be fully integrated into the thermoacoustic imaging system by sharing the microwave excitation source and the transducer. Moreover, the signals of the two imaging modalities do not interfere with each other due to the existence of the sound path difference, so that MUI can be performed simultaneously with microwave-induced thermoacoustic imaging. In the study, the performance characteristics and imaging capabilities of this hybrid system are demonstrated. The results indicate that our design provides one easy method for low-cost platform integration and has the potential to offer a clinically useful dual-modality tool for the detection of accurate diseases.
The high risk for type 2 diabetes among ethnic minority populations is not explained by low-grade inflammation (2019)

Our aim was to identify whether low-grade inflammation, reflected by C-reactive protein (CRP), explains the higher risk for incident type 2 diabetes (T2D) among ethnic minorities. We included 837 Dutch, 712 South-Asian Surinamese, 797 African Surinamese, 804 Ghanaian, 817 Turkish and 778 Moroccan origin participants of the HELIUS study (Amsterdam, the Netherlands). We used multiple linear regression to assess ethnic differences in CRP levels. We determined the association of CRP with T2D and the modifying effect of ethnicity by cox regression, and compared hazard ratios for the association between ethnicity and T2D before and after adjustment for CRP. CRP levels were higher in ethnic minority groups than in Dutch origin participants. CRP was associated with a higher T2D incidence, similarly across ethnic groups (overall HR per SD 1.38 [95% CI 1.14; 1.68]). However, the association was attenuated and no longer statistically significant after adjustment for adiposity measures (HR 1.11 [95% CI 0.90; 1.37]). CRP accounted for a very small part of the ethnic differences in T2D, but only in models unadjusted for adiposity. Low-grade inflammation does not substantially contribute to the higher risk of T2D among ethnic minority populations compared to the Dutch.
