A vignetting advantage for thin-film filter arrays in hyperspectral cameras (2020)

Vignetting in camera lenses is generally seen as something to avoid. For spectral cameras with thin-film interference filters, however, we argue that vignetting can be an advantage. When illuminated by focused light, the bandwidth of interference filters increases with the chief-ray angle, causing position-dependent smoothing of the spectra. We show that vignetting can be used to reduce smoothing and preserve important spectral features. Furthermore, we demonstrate that by adding additional vignetting to a lens, measurements can be made more consistent across the scene. This makes vignetting a useful parameter during spectral camera design.

Exo‐glucosidase activity and substrate specificity of the beta‐glycosidase isolated from the extreme thermophile Sulfolobus solfataricus (1993)

The enzyme with beta-galactosidase activity from Sulfolobus solfataricus strain MT-4, like other enzymes of this type isolated from thermophilic sources, has broad specificity for beta-D-gluco-, fuco- and galacto-sides. The beta-galactosidase activity was purified by a new procedure that improved yields (44%) and final specific activity (182 units mg-1 at 75 degrees C using chromogenic beta-D-galactoside as substrate). The enzyme hydrolysed a large number of beta-linked glycoside dimers and oligomers; chromogenic beta-glucosides and beta-fucosides are the preferred substrates, and kinetic analysis indicated that they bind to a common catalytic site. The order of catalytic efficiency was beta 1-3 > beta 1-4 > beta 1-6 and cellotetraose > cellotriose > cellobiose for glucose dimers and oliogomers respectively. The cleavage occurred at the non-reducing end of the oligosaccharide, and the enzyme showed noticeable specificity also for the aglycone part of substrates. From these results the enzyme from S. solfataricus strain MT-4 is defined as a true glycosyl hydrolase with remarkable exo-glucosidase activity and it is designated S beta-gly.

Design of a 55 W packaged GaN HEMT with 60% PAE by internal matching in S-band (2012)

This paper reports a package synthesis method in order to ensure good performances in PAE, output power and bandwidth. The internal matching circuits of the optimized package enable to reach the best impedance pre-matching at fundamental frequencies and also to confine the harmonic impedances seen by the internal GaN power bar into safe-efficiency regions whatever the external impedances presented to the package at second harmonic frequencies. In a 50Ω environment, the packaged GaN HEMT delivers 55 W output power associated with 60% PAE and 13.3 dB power gain at 2.7 GHz. By optimizing source and load impedances at the fundamental frequencies, the packaged GaN HEMT demonstrates more than 58% PAE from 2.6 GHz to 3.0 GHz.
Neutrophil F-actin and myosin but not microtubules functionally regulate transepithelial migration induced by interleukin 8 across a cultured intestinal epithelial monolayer. (1999)

The role of the polymorphonuclear leukocyte (PMN) cytoskeleton during the transmigration across colonic epithelial cells is not very well understood. In order to study the role of different components of the PMN cytoskeleton during transepithelial migration across a colonic epithelial cell monolayer (T84), PMN were preincubated with drugs affecting either the actin cytoskeleton (cytochalasin B, iota toxin of Clostridium perfringens, and phalloidin) or the microtubules (colchicine and taxol). The role of PMN myosin during transepithelial migration was investigated using the inhibitor 2,3-butanedione monoxime (BDM) and DC3B toxin. PMN intracellular Ca2+, during neutrophil adhesion and translocation across the epithelium, was assessed by the Ca2+ chelator 1, 2bis-(2-aminophenoxy)-ethane-N,N,N', N'-tetra-acetic acid tetrakis (acetoxymethyl) ester (BAPTA-AM). Transmigration of PMN was initiated by applying either interleukin-8 or formyl-met-leu-phe (fMLP). While colchicine and taxol preexposure did not influence PMN transepithelial migration, treatment with cytochalasin B, iota toxin, phalloidin, BDM, DC3B toxin and BAPTA-AM greatly diminished migration of PMN across T84 monolayers. Similarly, cell-cell contacts established between PMN and epithelial cells during the transmigration were diminished after treatment of PMN with iota toxin or cytochalasin B. These data show that the neutrophil actin cytokeleton and myosin, but not the microtubules, evoke a Ca2+ -dependent motility that facilitates migration across the colonic epithelial barrier.
[Functional and nutritional properties of modified proteins of sesame (Sesamum indicum, L.)]. (1984)

A study on the functional and nutritional properties of sesame (Sesamum indicum, L.) flour, concentrate and enzymatic hydrolysates, demonstrated that nitrogen solubility of the hydrolysates is improved, in water (85%) and at different pHs (91-95%), by the action of neutrasa 0.5L and alcalasa 0.6L, yielding a product with good emulsifying and improved foaming properties. Hydrolysates produced by the pH-stat method, then freeze-dried and spray-dried presented a PER of 1.1 and 0.9, respectively. The flour and the concentrate had PER values of 1.2. Supplementation of one of the hydrolysates with soya hydrolysate (1:1), improved the PER to a value similar to that of casein. Use of neutrasa 0.5L and alcalasa 0.6L enzymes, enhances the sesame protein solubility without modifying extensively the PER. Besides, it yields a dehydrated product with improved emulsifying and foaming properties.
Real-time "x-ray vision" for healthcare simulation: an interactive projective overlay system to enhance intubation training and other procedural training. (2011)

We have developed a prototype of a real-time, interactive projective overlay (IPO) system that creates augmented reality display of a medical procedure directly on the surface of a full-body mannequin human simulator. These images approximate the appearance of both anatomic structures and instrument activity occurring within the body. The key innovation of the current work is sensing the position and motion of an actual device (such as an endotracheal tube) inserted into the mannequin and using the sensed position to control projected video images portraying the internal appearance of the same devices and relevant anatomic structures. The images are projected in correct registration onto the surface of the simulated body. As an initial practical prototype to test this technique we have developed a system permitting real-time visualization of the intra-airway position of an endotracheal tube during simulated intubation training.
High Molecular Weight Kininogen Regulates Prekallikrein Assembly and Activation on Endothelial Cells: A Novel Mechanism for Contact Activation (1998)

The consequences of assembling the contact system of proteins on the surface of vascular cells has received little study. We asked whether assembly of these proteins on the surface of cultured human endothelial cells (HUVECs) results in the activation of prekallikrein (PK) and its dependent pathways. Biotinylated PK binds specifically and reversibly to HUVECs in the presence of high molecular weight kininogen (HK) (apparent Kd of 23 +/- 11 nmol/L, Bmax of 1.7 +/- 0.5 x 10(7) sites per cell [mean +/- SD, n = 5 experiments]). Cell-associated PK is rapidly converted to kallikrein. Surprisingly, the activation of cell-associated HK.PK complexes is entirely independent of exogenous factor XII (Km = 30 nmol/L, Vmax = 12 +/- 3 pmol/L/min in the absence v Km = 20 nmol/L, Vmax = 9.2 +/- 2.1 pmol/L/min in the presence of factor XII). Rather, kallikrein formation is mediated by an endothelial cell-associated, thiol protease. Cell-associated HK is proteolyzed during the course of prekallikrein activation, releasing kallikrein from the surface. Furthermore, activation of PK bound to HK on HUVECs promotes kallikrein-dependent activation of pro-urokinase, resulting in the formation of plasmin. These results indicate the existence of a previously undescribed, factor XII-independent pathway for contact factor activation on HUVECs that regulates the production of bradykinin and may contribute to cell-associated plasminogen activation in vivo.
Production of Conductive PEDOT-Coated PVA-GO Composite Nanofibers (2017)

Electrically conductive nanofiber is well known as an excellent nanostructured material for its outstanding performances. In this work, poly(3,4-ethylenedioxythiophene) (PEDOT)-coated polyvinyl alcohol-graphene oxide (PVA-GO)-conducting nanofibers were fabricated via a combined method using electrospinning and electropolymerization techniques. During electrospinning, the concentration of PVA-GO solution and the applied voltage were deliberately altered in order to determine the optimized electrospinning conditions. The optimized parameters obtained were 0.1 mg/mL of GO concentration with electrospinning voltage of 15 kV, which displayed smooth nanofibrous morphology and smaller diameter distribution. The electrospun PVA-GO nanofiber mats were further modified by coating with the conjugated polymer, PEDOT, using electropolymerization technique which is a facile approach for coating the nanofibers. SEM images of the obtained nanofibers indicated that cauliflower-like structures of PEDOT were successfully grown on the surface of the electrospun nanofibers during the potentiostatic mode of the electropolymerization process. The conductive nature of PEDOT coating strongly depends on the different electropolymerization parameters, resulting in good conductivity of PEDOT-coated nanofibers. The optimum electropolymerization of PEDOT was at a potential of 1.2 V in 5 min. The electrochemical measurements demonstrated that the fabricated PVA-GO/PEDOT composite nanofiber could enhance the current response and reduce the charge transfer resistance of the nanofiber.
Safety and treatment patterns of angiogenesis inhibitors in patients with advanced renal cell carcinoma in Spain (2013)

High rates of AEs were observed which resulted in high rates of treatment interruptions and dose reductions. These results suggest the need for additional treatment options for aRCC with improved tolerability.
Online learning combining virtual lectures, at-home experiments and computer simulations: a multidisciplinary teaching and learning approach (2021)

Selective affinity of one enantiomer of suriclone demonstrated by a binding assay with benzodiazepine receptors. (1986)

The binding of racemic 3H-suriclone on the BZD receptor was performed in special conditions in order to discriminate between the affinity of the two enantiomers: a rebinding method was used. In the first incubation 40% of 3H-suriclone was specifically bound to the BZD receptor. In the second incubation performed with the supernatant coming from the first incubation, less than 1% of the radiolabelled suriclone was specifically bound to the BZD receptor. These results suggest that most probably only one of the two enantiomers of suriclone may bind the BZD receptor. It appears that this enantiomer has the greatest affinity constant ever found for a BZD receptor agonist (Kd = 20 pM at 37 degrees C in presence of GABA and 70 pM in absence of GABA).

Why Does It Shine?—A Prognostic Analysis about Predisposing Factors for Blood–Brain Barrier Damage after Revascularisation of Cerebral Large-Vessel Occlusion (2023)

Our results support the prognostic value of hyperdense lesions after EVT. We identified the volume of the lesion, the affection of grey matter and the plasmatic coagulation system as independent factors for the development of such lesions.
Some Remarks on the Condensation Phenomena (1950)

(A) Isothermal compression of gas produces another phase, whose physical properties are much different from those of gas, i.e., liquid phase; and further compression makes at last whole system liquid phase only. (B) In some range of above mentioned process, pressure remains constant against change of volume, i.e., has a horizontal part. (A) and (B) are at first sight independent from each other. The theory presented heretofore seems to aim to prove principally (B) (for example, works of Mayero, Kahn and Uhlenbeck2), Born and FuchsS), etc.). The fact (A), however, seems to be more fundamental, so that present paper aims to prove (A) as well as (B), and to investigate correspondence between II coexistence state of two phases in (A) and the horizontal part of pv-curve in (B).

Photocyclization Reactions of Aryl Polyenes. V. Photochemical Synthesis of Substituted Chrysenes (1972)

The photocyclization-oxidation reaction of 1,6-di-p-substituted-phenyl-1,3,5-hexatrienes gave 3,9-disubstituted-chrysenes. Similarly, irradiation of 1-p-substituted-phenyl-6-phenyl-1,3,5-hexatrienes yielded 3-substituted-chrysenes. The 3-substituted-chrysenes were independently prepared in a high yield by the photocyclization-oxidation of 1-α-naphthyl-2-p-substituted-phenylethylenes.

THICKNESS REQUIREMENTS FOR UNSURFACED ROADS AND AIRFIELDS. BARE BASE SUPPORT (1970)

Abstract : A method was developed for determining design thickness requirements for unsurfaced airfields. Tests were conducted on a total of 43 unsurfaced test items. These items had varying thicknesses and were trafficked under different loading conditions. CBR, water content, density, deflection, and deformation data were recorded throughout testing. The design expression relates thickness requirements to soil response in terms of applications of load, load magnitude and pressure, and strength of soil. (Author)
Achievements in cholinergic research, 1969-1989: drug development. (1990)

Publisher Summary This chapter discusses the achievements of drug development in cholinergic research, 1969–1989. The past two decades have seen a flood of new information on the components of cholinergic systems and the functional relationships among them. The techniques of molecular biology, ultrastructural morphology, radioligand binding, and analytical chemistry have played major roles in these advances and in turn have depended on the availability of specific high-affinity or irreversible ligands, such as drugs. The emphasis on enhancement of cholinergic function that has characterized the past decade will at best yield drugs, which are of temporary and symptomatic benefit. It seems likely that the years to come will provide a better understanding of the processes controlling development, differentiation, maintenance, and repair of cholinergic neurons. This will lead to a new generation of drugs, which modulate these processes. The next 20 years may well see advances in neurochemistry and pharmacology, which will allow presymptomatic diagnosis and even prophylaxis of the progressive degenerative diseases that threaten the present generation.

Nonlinear integrated optics (1990)

Experimental nonlinear optics, born just after the discovery of the laser with the first experiment of second harmonic generation performed by P Franken and co-workers in 1961, is currently undergoing a revolution due to the impact of guided wave technology. In the early days, experiments had to use bulky and inefficient high power lasers as primary sources, greatly reducing the possibility of device development. thanks to the guided wave configuration it has become possible to use lower power pump sources, in particular diode lasers, opening the way to compact, reliable devices. The devices are based on two types of guides, optical fibres and integrated optical guides – microguides or semiconductor substrates.
Revealing the insoluble metasecretome of lignocellulose-degrading microbial communities (2017)

Microbial communities metabolize plant biomass using secreted enzymes; however, identifying extracellular proteins tightly bound to insoluble lignocellulose in these microbiomes presents a challenge, as the rigorous extraction required to elute these proteins also lyses the microbes associated with the plant biomass releasing intracellular proteins that contaminate the metasecretome. Here we describe a technique for targeting the extracellular proteome, which was used to compare the metasecretome and meta-surface-proteome of two lignocellulose-degrading communities grown on wheat straw and rice straw. A combination of mass spectrometry-based proteomics coupled with metatranscriptomics enabled the identification of a unique secretome pool from these lignocellulose-degrading communities. This method enabled us to efficiently discriminate the extracellular proteins from the intracellular proteins by improving detection of actively secreted and transmembrane proteins. In addition to the expected carbohydrate active enzymes, our new method reveals a large number of unknown proteins, supporting the notion that there are major gaps in our understanding of how microbial communities degrade lignocellulosic substrates.

Modeling of deep-submicrometer MOSFETs: random impurity effects, threshold voltage shifts and gate capacitance attenuation (2002)

The authors present simulation results for the subthreshold characteristics of n-channel MOSFETs with 0.1 /spl mu/m gate-length and 0.05 /spl mu/m gate-width obtained with our 3D-DD simulator. We also presented a new method that one can successfully use in a particle-based simulator to properly account for the short-range portions of the e-e and e-i interactions without double-counting the long-range portions of these two interaction terms.
