The END3 gene encodes a protein that is required for the internalization step of endocytosis and for actin cytoskeleton organization in yeast. (1994)

Two Saccharomyces cerevisiae mutants, end3 and end4, defective in the internalization step of endocytosis, have previously been isolated. The END3 gene was cloned by complementation of the temperature-sensitive growth defect caused by the end3 mutation and the END3 nucleotide sequence was determined. The END3 gene product is a 40-kDa protein that has a putative EF-hand Ca(2+)-binding site, a consensus sequence for the binding of phosphotidylinositol 4,5-bisphosphate (PIP2), and a C-terminal domain containing two homologous regions of 17-19 aa. The EF-hand consensus and the putative PIP2-binding sites are seemingly not required for End3 protein function. In contrast, different portions of the End3p N-terminal domain, and at least one of the two repeated regions in its C-terminus, are required for End3p activity. Disruption of the END3 gene yielded cells with the same phenotype as the original end3 mutant. An end3ts allele was obtained and this allowed us to demonstrate that End3p is specifically involved in the internalization step of endocytosis. In addition, End3p was shown to be required for proper organization of the actin cytoskeleton and for the correct distribution of chitin at the cell surface.
Dynamic-SIMD for lens distortion compensation (2006)

An increasing computational demand is placed on the image processing capacity of current and future smart cameras. SIMD processor architectures provide an efficient solution because their repetitive structure matches the data-parallel execution pattern inherent in pixel-type processing. But the lack of support for communicating pixel data over variable distances has forced designers to allocate dedicated hardware or FPGAs for compensating lens distortion and other non-linear operations. We propose a hardware extension to SIMD processors that enables dynamic communication. Using detailed area cost models and a high-level simulator we optimize the extension with regard to the number of buses, bus arbitration policies, and local instruction buffer sizes
Priority-based coordination of autonomous and legacy vehicles at intersection (2014)

Recently, researchers have proposed various intersection management techniques that enable autonomous vehicles to cross the intersection without traffic lights or stop signs. In particular, a priority-based coordination system with provable collision-free and deadlock-free features has been presented. In this paper, we extend the priority-based approach to support legacy vehicles without compromising above-mentioned features. We make the hypothesis that legacy vehicles are able to keep a safe distance from their leading vehicles. Then we explore some special configurations of system that ensures the safe crossing of legacy vehicles. We implement the extended system in a realistic traffic simulator SUMO. Simulations are performed to demonstrate the safety of the system.
Spectral line-by-line pulse shaping (2005)

We experimentally demonstrate pulse-shaping experiments in which the individual spectral lines that are present in the output of a mode-locked laser (8.5 GHz mode spacing, centered at 1542 nm) are resolved. The shaped pulses overlap in time, and this leads to a new way to observe fluctuations of the comb-offset frequency in the time domain.
Experiments on shock wave reflection transition and hysteresis in low-noise wind tunnel (2003)

Experiments on the transition between steady regular and Mach reflections of shock waves have been performed in a low-noise wind tunnel. Owing to a very low level of free-stream disturbances inherent in this facility, the hysteresis phenomenon has been observed in close agreement with theoretical predictions and results of the previous numerical simulations. When increasing the incident shock wave angle, regular reflection persists in most of the dual solution domain. Thus, the detachment criterion can be considered as a true one for the transition from regular to Mach reflection, and an earlier transition observed in many wind tunnel experiments is certainly caused by free-stream disturbances, which were present in those facilities.
An index implementation supporting fast recovery for the POSTGRES storage system (2003)

The authors present two algorithms for maintaining B-tree index consistency in a database management system which does not use write-ahead logging (WAL). One algorithm is similar to shadow paging, but improves performance by integrating shadow meta-data with index meta-data. The other algorithm uses a two-phase page reorganization scheme to reduce the space overhead caused by shadow paging. Although designed for the POSTGRES storage system, these algorithms should also be useful in a WAL-based storage system, as support for logical logging. Measurements and analysis of a prototype implementation suggest that the algorithms will have little impact on data manager performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Experimental and theoretical study of novel grooved horn antenna (2002)

Horn antennas play a very important role in microwave engineering. To meet different kinds of need, several types of horn including conical, pyramidal, ridge-loaded, corrugated horns, etc. have been developed and studied extensively. These horns can be classified as pure mode or multi-mode horns due to the field distribution (waveguide mode) on the apertures. In this paper, a new grooved type of horn with a cross-section similar to a groove guide is presented. Initial work shows that such horns have the advantages of more flexible design and pure mode operation and hence excitation is easy. Various radiation patterns can be obtained by choosing appropriate cross-section shape and size.
Fertilization of the eggs of bivalve mollusks with different insemination conditions. (1975)

Eggs of the bivalve mollusks Ostrea gigas, Spisula sachalinensis, and Mactra sulcataria taken from the ovary and placed in sea water are capable of maturation: the nuclear membrane dissolves and polar body I is released. The percentage of such spontaneously ripening eggs differs widely in different females and apparently characterizes the degree of roe maturity. The fertilization rate of roe containing a small percentage of spontaneously maturing eggs increases considerably during holding in sea water and remains at a high level for several hours. Maximum percentage fertilization can be obtained only over a narrow range of sperm concentrations in suspension for the species studied. A concentration of 10-6 or 10-7 sperm/cm-3 is usually optimum; a decrease or increase in sperm concentration by an order of magnitude (in comparison with the optimum level) reduces percentage fertilization. It was shown that sperm in suspensions with concentrations above the optimum level are activated to a lesser extent and their speed of movement is less than at high dilutions.
THE PERSISTENCE AND POSSIBLE EXTERNALIZATION OF AXONAL DEBRIS DURING WALLERIAN DEGENERATION (1979)

The sequence of changes in transected rat sciatic nerves were subjected to parallel ultrastructural and biochemical studies. Widespread granular disintegration of axoplasmic microtubules and neurofilaments occurred in the 24--72 hour interval following nerve transection. These changes were associated with a loss of neurofilament proteins and a marked enhancement of 53,000, 70--73,000 and 85,000 MW proteins in transected nerve. The emergence of prominent nerve proteins during the aftermath of axonal degeneration supports their derivation from axonal sources. These three proteins remained prominent components in transected nerves and comprised the major proteins found in 34-day transected nerves. Amorphous granular breakdown products from myelinated and unmyelinated nerve fibers were encountered with progressively decreasing frequency after 48 hours. This diminution of intracellular axonal debris was accompanied by the appearance and increasing prominence of amorphous granular deposits within the endoneurium of transected nerves. These endoneurial deposits became closely associated with collagen fibers and persisted as a prominent component in 34-, 80- and 120-day transected nerves. It is suggested that the amorphous endoneurial granular deposits arise in part from the externalization of granular axoplasmic breakdown products. Externalized axonal components could have important implications for tissue reaction to injury.
MEMS variable optical attenuator with vernier latching mechanism (2005)

A microelectromechanical-systems-based moving fiber variable optical attenuator (VOA) with a Vernier latching mechanism is described in this letter. Controlled misalignment between the end-faces of two optical fibers varies the optical coupling. This is performed using a Chevron-type thermal microactuator which moves one fiber end-face with respect to the other. The moving fiber is latched in positions using a Vernier latching mechanism with 0.5-μm step resolution. A prototype VOA has been fabricated using 80-μm silicon-on-insulator. Optical power coupled between the two single-mode fibers varied from 3.72 to -44 dBm, and over this range the VOA latched in 30 stable positions. Insertion loss was measured to be 1.05 dB. In the unlatched mode, the 10%-90% and the 90%-10% response times of the system were measured to be 1.7 and 4.8 ms, respectively.
Synthesis and antimicrobial activities of novel n-substituted 8-(1-alkyl/alkylsulphonyl/alkoxycarbonyl-benzimidazol-2-ylmethoxy)-5-chloroquinolines (2011)

Herein the synthesis of a series of novel 8-(1- alkyl/alkylsulphonyl/alkoxycarbonyl-benzimidazol-2-ylmethoxy)-5- chloroquinoline derivatives is reported. These derivatives were prepared by the condensation of o-phenylenediamine with [(5-chloroquinolin-8- yl)oxy]acetic acid, followed by substitution at nitrogen with different electrophilic reagents in presence of an appropriate base to give a series of nitrogen heterocycles containing the benzimidazole and quinoline nuclei. The structures of the compounds were confirmed based on 1H-NMR, 13CNMR, IR and mass spectral data. Almost all the compounds exhibited promising antibacterial activity against Salmonella typhimurium and Staphylococcus aureus. Some of the compounds showed good antifungal activities against Aspergillus niger but the antifungal activities against Candida albicans were disappointing.
X-ray laser emission from a laser-irradiated gas puff target (2005)

The paper describes the research on soft X-ray lasers with an active medium created using a gas puff target irradiated with high-intensity laser pulses. The gas puff target in a form of an elongated gas sheet is produced by pulsed injection of gas through a slit nozzle using a high-pressure electromagnetic valve. The method of generation of soft X-ray lasers using a laser-irradiated gas puff target has been developed at the Institute of Optoelectronics. The collaborative experiments were performed at various laser laboratories using high-intensity laser systems to irradiate the gas puff target and pump the X-ray laser active medium. Results of these experiments are presented and discussed. Works aimed at increasing the efficiency of X-ray lasers using a longitudinally irradiated gas puff target are also reviewed.
Effect of Tropical Photoperiods on the Growth of Sorghum When Grown in 12 Monthly Plantings<sup>1</sup> (1968)

Effects of day length on number of days to anthesis and plant height were observed on 15 tropical sorghums ( Sorghum bicolor (L.) Moench) and compared with 7 U.S. sorghums and a set of 8 maturity genotype testers. Plantings were made for 12 consecutive months in 1964 and 1965. Plantings made as much as 230 days apart flowered within a 17‐day period in November while plantings separated by only 30 days reached anthesis as much as 200 days apart. Tropical sorghums appeared to have a lower critical photoperiod than the U.S. sorghums. It was possible, however, to bring all types into flower at about the same time in Puerto Rico by planting in mid‐September through mid‐November when day lengths were below the critical level for the varieties. Data indicated that photoperiodic thresholds varied because the sorghums could be separated into five general response classes. Variation in floral induction time was strongly suggested. Among the eight maturity genotype testers, photoperiodic response was observed only in 100‐ day Milo and 90‐day Milo, varieties containing both dominant genes, Ma 1 and Ma 2 . None of the other genotypes were significantly affected by the Puerto Rico environment. This indicated that their critical photoperiod must be above 13 hours. Significant correlation was observed between days from planting to anthesis and plant height in most of the tropical sorghums, but not for the U.S. sorghums which were unaffected by changes in the photoperiod.
Deformable random dot markers (2011)

We extend planar fiducial markers using random dots [8] to nonrigidly deformable markers. Because the recognition and tracking of random dot markers are based on keypoint matching, we can estimate the deformation of the markers with nonrigid surface detection from keypoint correspondences. First, the initial pose of the markers is computed from a homography with RANSAC as a planar detection. Second, deformations are estimated from the minimization of a cost function for deformable surface fitting. We show augmentation results of 2D surface deformation recovery with several markers.
New technological windows into mind (1996)

This is an overview of the recent progress leading towards a full subject-centered paradigm in human-computer interaction. At this new phase in the evolution of computer technologies it will be possible to take into account not just characteristics of average human beings, but create systems sensitive to the actual states of attention and intentions of interacting persons. We discuss some of these methods concentrating on the eye-tracking and brain imaging. The development is based on the use of eye movement data for a control of output devices, for gaze-contingent image processing and for disambiguating verbal as well as nonverbal information.
Generation and Degradation of Fibrinopeptide A inStored Platelet Concentrate (1986)

The levels of fibrinopeptide A (FPA) were measured in samples from stored platelet concentrates (PC) by radioimmunoassay. In 27 standard, citrated PC, the mean FPA was 13.6 ng/ml, which is elevated 5-6X over background levels. This value did not change significantly over a 7-day storage period. Addition of PGE-1 and theophylline resulted in higher initial levels of FPA (18.0 ng/ml) and a pronounced rise during the storage period (to 43.4 ng/ml by day 10). In contrast, addition of a thrombin inhibitor, D-phenylalanyl-L-prolyl-L-arginine chloromethyl ketone - 2 HCl (PPACK) or hirudin, resulted in lower initial levels of FPA relative to standard, citrated PC and a slow increase over time. Introduction of exogenous FPA into citrated PC resulted in a predicted elevation of FPA levels followed by a rapid loss of immunoreactivity (t^(1/2) =18 h). Addition of PPACK did not affect this fall-off. However, PC prepared and stored in the presence of PGE-1 and theophylline showed a much slower fall-off of exogenous FPA (t^(1/2) = 38 h). These data indicate that FPA levels in samples from citrated PC represent a dynamic balance between generation and degradation processes and, thus, the data above underestimate the amount of thrombin activity present in stored, citrated PC.
A neural network multiagent architecture applied to fieldbus intelligent control (2008)

This paper presents a multiagent architecture applied to factory automation. These agents detect faults in process automation and allocate intelligent algorithms in field device function blocks to solve these faults. It is also present a dynamic function block parameter exchange strategy which allows agent fieldbus allocation. The objective is to enable problem detection activities independent of user intervention. The use of artificial neural network (ANN)- based algorithms enables the agents to learn about fault problem patterns and adapt an algorithm that can be used in fault situations. With this, the intention is reduce supervisor intervention in selecting and implementing an appropriate structure of function block algorithms. These algorithms, when implemented in device function blocks, provide a solution at fieldbus level, reducing data traffic between gateway and device.
p-Nitrophenol permeability and temperature characteristics of an acryloyl-L-proline methyl ester-based porous gel membrane (1998)

Thermoresponsive porous gel membranes were synthesized by a simultaneously occurring process consisting of radiation-induced polymerization and crosslinking in aqueous solutions at various concentrations of acryloyl-L-proline methyl ester(A-ProOMe) without a crosslinker. Permeation of p-nitrophenol (PNP) through a thermoresponsive porous gel membrane obtained at a monomer concentration of 80% (w/w) drastically reduced around 14°C, the lower critical solution temperature (LCST) of linear poly(A-ProOMe) in water, from 0.60 × 10−3 cm/min at 10°C to no permeation at 18°C, accompanied by changes in both size and shape of pores associated with gel shrinkage. Moreover, it was found that porous gel membranes with a porosity of approximately 60% had a greater PNP permeability constant through porous gel membranes with mutually connected pores obtained at a monomer concentration of 50% (w/w) than individually supported pores obtained at a monomer concentration of 70% (w/w). © 1998 John Wiley & Sons, Inc.

Field-Induced Structures in Ferrofluid Emulsions (1995)

The field-induced structure in a monodisperse ferrofluid emulsion is studied. An applied magnetic field induces a magnetic dipole moment in each droplet. When the dipole-dipole interaction energy exceeds the thermal energy, a phase transition occurs as the fluid of randomly dispersed droplets changes to a solid of nearly equally sized and spaced columns. Our results show that the column spacing follows a relation ${d\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.33L}^{0.37}$ for cell thickness $3\ensuremath{\le}L\ensuremath{\le}800\ensuremath{\mu}\mathrm{m}$. A new theory, which treats the column shape more realistically, is developed to account for the results.
INFRARED HEADLAMPS FOR ACTIVE NIGHT-VISION SYSTEMS (2001)

The potential for active night-vision systems to increase the visual range without dazzling oncoming traffic is explored. The system is based on an infrared headlamp, a camera and a visual display. Near infrared radiation is particularly suitable for this application. The available light sources for infrared headlamps include halogen bulbs, gas discharge bulbs and light-emitting or laser diodes. Tests on infrared headlamps in a light tunnel showed that they illuminated pedestrians effectively even at a considerable distance. The use of a projection lamp with infrared-transmissive shield enables the production of a headlamp that generates a dipped beam and infrared main beam at the same time. A first concept for an infrared headlamp using infrared light-emitting diodes has been realised as a prototype. For the covering abstract see ITRD E123380.
Cord Blood Transplantation and the Potential for Gene Therapy (1995)

Cord blood, which contains a high frequency of immature stem/progenitor cells with extensive proliferative and replating capacity in vitro was used as a clinical source of transplantable stem and progenitor cells. These cells can be efficiently transduced with new genetic material by using AAV or retroviral vectors. Using a recombinant AAV vector, high level expression of the lacZ gene under a CMV promoter was demonstrated in immature subsets of cord blood progenitor cells.
The simultaneous release by bone explants in culture and the parallel activation of procollagenase and of a latent neutral proteinase that degrades cartilage proteoglycans and denatured collagen (1978)

1. A latent neutral proteinase was found in culture media of mouse bone explants. Its accumulation during the cultures is closely parallel to that of procollagenase; both require the presence of heparin in the media. 2. Latent neutral proteinase was activated by several treatments of the media known to activate procollagenase, such as limited proteolysis by trypsin, chymotrypsin, plasmin or kallikrein, dialysis against 3 M-NaSCN at 4 degrees C and prolonged preincubation at 25 degrees C. Its activation often followed that of the procollagenase present in the same media. 3. Activation of neutral proteinase (as does that of procollagenase) by trypsin or plasmin involved two successive steps: the activation of a latent endogenous activator present in the media followed by the activation of neutral proteinase itself by that activator. 4. The proteinase degrades cartilage proteoglycans, denatured collagen (Azocoll) and casein at neutral pH; it is inhibited by EDTA, cysteine or serum. Collagenase is not inhibited by casein or Azocoll and is less resistant to heat or to trypsin than is the proteinase. Partial separation of the two enzymes was achieved by gel filtration of the media but not by fractional (NH4)2SO4 precipitation, by ion exchange or by affinity chromatography on Sepharose-collagen. These fractionations did not activate latent enzymes. 5. Trypsin activation decreases the molecular weight of both latent enzymes (60 000-70 000) by 20 000-30 000, as determined by gel filtration of media after removal of heparin. 6. The latency of both enzymes could be due either to a zymogen or to an enzyme-inhibitor complex. A thermostable inhibitor of both enzymes was found in some media. However, combinations of either enzyme with that inhibitor were not reactivated by trypsin, indicating that this inhibitor is unlikely to be the cause of the latency.
