Compact microchip optical parametric oscillator (2003)

Summary form only given. The interest in OPOs have been renewed last years because of advances in solid-state pump lasers and new nonlinear-optical materials. The use of the OPO concept in industrial compact systems such as range-finders or gas detectors require the reduction of pump laser size. The objective of the work was to use a Q-switched Nd:YAG microchip laser to pump an OPO and thus to obtain a Q-switched high-frequency all-solid-state light-source emitting between 1.3 /spl mu/m and 4 /spl mu/m.
Structural and Optical Properties of Self-Catalyzed Axially Heterostructured GaPN/GaP Nanowires Embedded into a Flexible Silicone Membrane (2020)

Controlled growth of heterostructured nanowires and mechanisms of their formation have been actively studied during the last decades due to perspectives of their implementation. Here, we report on the self-catalyzed growth of axially heterostructured GaPN/GaP nanowires on Si(111) by plasma-assisted molecular beam epitaxy. Nanowire composition and structural properties were examined by means of Raman microspectroscopy and transmission electron microscopy. To study the optical properties of the synthesized nanoheterostructures, the nanowire array was embedded into the silicone rubber membrane and further released from the growth substrate. The reported approach allows us to study the nanowire optical properties avoiding the response from the parasitically grown island layer. Photoluminescence and Raman studies reveal different nitrogen content in nanowires and parasitic island layer. The effect is discussed in terms of the difference in vapor solid and vapor liquid solid growth mechanisms. Photoluminescence studies at low temperature (5K) demonstrate the transition to the quasi-direct gap in the nanowires typical for diluted nitrides with low N-content. The bright room temperature photoluminescent response demonstrates the potential application of nanowire/polymer matrix in flexible optoelectronic devices.
Response to Inhaled Nitric Oxide in Patients with Acute Right Heart Syndrome (1999)

Inhaled nitric oxide (iNO), a selective pulmonary vasodilator, has been shown to decrease pulmonary artery pressures but not increase cardiac output in hemodynamically stable patients with a variety of causes of pulmonary hypertension. The response to iNO in hemodynamically unstable patients with acute right heart syndrome has not been previously described. We determined the response to iNO in 26 critically ill adult patients with acute right heart failure defined by echocardiographic criteria. Patients received iNO through the inspiratory limb of the ventilator in increments of 10 ppm with hemodynamic and gas-exchange measurements made before and after each level. When maximal effect was seen, iNO was discontinued to compare parameters with baseline. iNO significantly increased cardiac output (5.5 +/- 3 to 6.4 +/- 4 L/min), stroke volume (54 +/- 27 to 65 +/- 38 ml), and mixed-venous oxygen saturation (69 +/- 8 to 73 +/- 10%), all p < 0.01. With discontinuation of iNO, all parameters returned immediately to baseline. These parameters of improved perfusion were related to a decrease in pulmonary vascular pressures and resistance. In a subset of approximately 50% of patients, these changes were substantial (> 20%) and in approximately 25% of all patients, the improvement in hemodynamic measures permitted a decrease in other vasoactive drug administration. The mean concentration of iNO required to achieve these effects was 35 ppm, and 85% of patients exhibiting a substantial improvement in hemodynamics did so at a concentration of iNO of less than or equal to 40 ppm. Underlying causes of right heart failure and baseline hemodynamics did not predict response to iNO, but the use of alpha-agonist catecholamines did. We conclude iNO improves hemodynamics in patients with respiratory failure, shock, and right ventricular dysfunction. Although mortality was not a key end point in this pilot study, it was high for both responders and nonresponders to this therapy. Further evaluation of the role of iNO in this patient population is supported by these data.

Renegotiated CBR transmission in interactive video-on-demand system (1997)

An interactive video-on-demand (IVOD) system requires transmission bandwidth allocation for each user. Since the volume of data in each video frame is variable, dynamic bandwidth allocation is desirable. In this paper, a new scheme that dynamically determines required bandwidth based on the queue length at the viewer's set-top box (STB) is proposed. Although this method is in the renegotiated CBR (constant bit rate) category, it requires no precalculation, so it is easily applied to IVOD. The variance of the video transmission rate for each user is an important factor as it affects the service quality of other multiplexed traffic. It is desirable that the transmission rate is changed gradually. A multi-layer concept is introduced to achieve this. Through numerical evaluation using actual movie data, we demonstrate that the variance of the transmission rate is close to the optimal value and the bandwidth utilization is close to unity.
Latent Fingerprint Aging from a Hyperspectral Perspective: First Qualitative Degradation Studies Using UV/VIS Spectroscopy (2015)

Latent print age estimation is an important topic in the emerging field of digitized crime scene forensics. While several capturing devices have recently been studied towards this goal, hyperspectral imaging in the UV/VIS (ultraviolet and visible light) range of the electromagnetic spectrum has not been investigated so far. Addressing this research gap, a first qualitative evaluation on the aging behavior of 30 latent print time series from 6 different donors is conducted, utilizing an optical reflection spectrometer. Results show more unpredictable aging tendencies in the ultraviolet spectral range, whereas a general logarithmic trend from prior work (using non-spectral capturing devices) is confirmed for the visible light band. Furthermore, a different behavior of eccrine and sebaceous print components is found, especially in the ultraviolet band, where sebaceous components seem to become reflective to the emitted radiation and might furthermore be utilized for studying longer aging periods in contrast to eccrine prints. Overall, the combined degradation information of the ultraviolet and the visible light band seem to provide the most reliable results for measuring a reproducible aging trend, serving as a potential opportunity to address the strong influence of different sweat compositions on the aging behavior of latent prints.
Photovoltaic hot spot mitigation using voltage-threshold control at the panel level (2015)

Maximum power point tracking (MPPT) for photovoltaic (PV) panels is primarily implemented at the panel level in presently-installed PV systems. Each panel typically consists of three subpanel strings with a bypass diode connected over each subpanel. When a panel becomes partially-shaded, the MPPT control may bypass a substring to optimize power, however, bypassing increases hot spotting risk. This paper introduces a voltage-threshold control that works with existing MPPT to mitigate hot spotting. The control imposes a lower voltage limit that prevents a compromised subpanel string from being bypassed. Simulation results show that voltage-threshold control is effective in limiting hot spotting for both typical Type A and Type B PV cells, with only minimal reduction in energy output.
Hepatotrophic Effect of Portal Blood during Hepatic Arterial Recirculation (1986)

Portal branch ligation (PBL) is known to induce a rapid and progressive atrophy in the liver parenchyma without portal blood flow and compensatory hyperplasia in the segments receiving the whole portal flow. In this study, the hepatotrophic effect of portal blood was studied in rats with PBL and after this procedure was combined with different portosystemic shunts. After 2 weeks, the most severe atrophy was found in ligated lobes of rats with PBL alone. In shunted animals, the atrophy was significantly inhibited and in relation to the magnitude of portal flow bypassed the liver. This suggests that in shunted rats, the portal-borne hepatotrophic factors undergo systemic recirculation and affect the liver by way of the hepatic artery. Stimultaneously, in PBL + shunt rats, the rate of atrophy normally induced by a shunt was also dependent on the amount of portal blood available to this part of the liver. By a balance between these 2 processes, the total liver mass was maintained at the level found in sham PBL + shunt control rats.
Logical and arithmetic circuits in Belousov-Zhabotinsky encapsulated disks (2011)

Excitation waves on a subexcitable Belousov-Zhabotinsky (BZ) substrate can be manipulated by chemical variations in the substrate and by interactions with other waves. Symbolic assignment and interpretation of wave dynamics can be used to perform logical and arithmetic computations. We present chemical analogs of elementary logic and arithmetic circuits created entirely from interconnected arrangements of individual BZ encapsulated cell-like disk. Interdisk wave migration is confined in carefully positioned connecting pores. This connection limits wave expansion and unifies the input-output characteristic of the disks. Circuit designs derived from numeric simulations are optically encoded onto a homogeneous photosensitive BZ substrate.
Modulating subwavelength transmission in nanoaperture arrays with metallic nanoparticles (2010)

Optical transmission through subwavelength nanoaperture arrays can be modulated by metallic nanoparticles that are nested in the nanoaperture. The localized surface plasmon resonance of nanoparticles can strongly modulate and in some cases dominate the transmission.
Immunohistochemical detection of gamma-glutamyl transpeptidase in normal human tissue. (1996)

We developed a new, highly specific antibody that localizes gamma-glutamyl transpeptidase (GGT) in formalin-fixed sections of human tissue. The specificity of the antibody, GGT129, is demonstrated by immunostained Western blots of whole cell homogenate from five different tissues. The utility of the antibody is shown by a comprehensive study of GGT expression in normal human tissue. This study reveals GGT expression for the first time in a number of tissues, including glands in the endocervix, endometrium, and adrenals. Strong immunoreactivity was observed on the surface of renal proximal tubule cells, hepatic bile canaliculi, and capillary endothelial cells within the nervous system. Secretory or absorptive cells in sweat glands, prostate, salivary gland ducts, bile ducts, pancreatic acini, intestinal crypts, and testicular tubules were also GGT-positive. Small bands of positively stained stromal cells and GGT-positive histiocytes were seen in some tissues. Analysis of human fetal tissue shows that the developmental expression of GGT differs in humans and rodents. These findings form the basis for further work on GGT induction in tumors and the effect of GGT expression on the response of tumors to chemotherapy.
Challenges and opportunities for millimeter-wave mobile access standardisation (2014)

This paper presents the main advantages and challenges that the introduction of millimeter-wave mobile access brings to the forthcoming 5G system architecture, focusing on the expected impact of that technology on standards and regulation bodies. The EU-funded project MiWaveS is taken as a concrete example for the standardization impact.
New Application of Seawater and Electrolyzed Seawater in Air Pollution Control of Marine Diesel Engine. (2003)

It is the purpose of this paper to introduce the usage of seawater and its electrolysis for the exhaust emission control in marine diesel engines. First, with using only seawater that is naturally alkaline (pH typically around 8.1), the SO2 and SO3 are absorbed by relatively high solubility compared to other components of exhaust pollutants, and PMs (Particulate Matter) are removed through direct contact with the sprayed seawater droplets. Besides, the electrolyzed alkaline seawater by electrolysis, which contains mainly NaOH together with alkali metal ions (i. e. Na+, Mg2+, Ca2+), is used as the absorption medium of NOx and CO2. Conditionally, before the NOx absorption treatment with using the alkaline seawater, nitric oxide (NO) must be adequately oxidized to nitrogen dioxide (NO2) by the acidic seawater in order to increase NOx absorption rate into the alkaline seawater. Because NOx absorption is the most suited to conditions when both volume fractions (NO: NO2 ratio) are of equal portions. Finally, this research would also plan to treat the effluent by applying electro-dialysis and electro-flotation techniques in the future. The way to reduce emissions from the marine diesel engines is to make it attractive from an operating perspective, as well as an environmental perspective.
GPU Parallel Implementation of Isometric Mapping for Hyperspectral Classification (2017)

Manifold learning algorithms such as the isometric mapping (ISOMAP) algorithm have been widely used in the analysis of hyperspectral images (HSIs), for both visualization and dimension reduction. As advanced versions of the traditional linear projection techniques, the manifold learning algorithms find the low-dimensional feature representation by nonlinear mapping, which can better preserve the local structure of the original data and thus benefit the data analysis. However, the high computational complexity of the manifold learning algorithms hinders their application in HSI processing. Although there are a few parallel implementations of manifold learning approaches that are available in the remote sensing community, they have not been designed to accelerate the eigen-decomposition process, which is actually the most time-consuming part of the manifold learning algorithms. In this letter, as a case study, we discuss the graphics processing unit parallel implementation of the ISOMAP algorithm. In particular, we focus on the eigen-decomposition process and verify the applicability of the proposed method by validating the embedding vectors and the subsequent classification accuracies. The experimental results obtained on different HSI data sets show an excellent speedup performance and consistent classification accuracy compared with the serial implementation.

Identification of synapsin I peptides that insert into lipid membranes (2001)

The synapsins constitute a family of synaptic vesicle-associated phosphoproteins essential for regulating neurotransmitter release and synaptogenesis. The molecular mechanisms underlying the selective targeting of synapsin I to synaptic vesicles are thought to involve specific protein-protein interactions, while the high-affinity binding to the synaptic vesicle membrane may involve both protein-protein and protein-lipid interactions. The highly hydrophobic N-terminal region of the protein has been shown to bind with high affinity to the acidic phospholipids phosphatidylserine and phosphatidylinositol and to penetrate the hydrophobic core of the lipid bilayer. To precisely identify the domains of synapsin I which mediate the interaction with lipids, synapsin I was bound to liposomes containing the membrane-directed carbene-generating reagent 3-(trifluoromethyl)-3-(m-[125I]iodophenyl)diazirine and subjected to photolysis. Isolation and N-terminal amino acid sequencing of 125I-labelled synapsin I peptides derived from CNBr cleavage indicated that three distinct regions in the highly conserved domain C of synapsin I insert into the hydrophobic core of the phospholipid bilayer. The boundaries of the regions encompass residues 166-192, 233-258 and 278-327 of bovine synapsin I. These regions are surface-exposed in the crystal structure of domain C of bovine synapsin I and are evolutionarily conserved among isoforms across species. The present data offer a molecular explanation for the high-affinity binding of synapsin I to phospholipid bilayers and synaptic vesicles.
What'S new: The role of chaotropic salts in two‐phase gene diagnosis (1984)

Abstract The preparation of samples for gene diagnosis is time‐consuming, labor‐intensive and costly. These problems can be overcome by dissolving a biological source in a strong solution of a chaotropic salt, then filtering the solution through an immobilizing membrane. Conditions exist for causing the selective immobilization of either DNA or mRNA. The resultant membrane is immediately ready for reaction with labeled gene probes.

An experimental study on Cartesian tracking control of automated excavator system using TDC-based robust control design (1999)

The Cartesian control of automated excavators has been noted for its difficulty, especially due to severe nonlinearities in hydraulic actuators that can be hardly observed in electric motors. The nonlinearities tend to become even more severe as the size of an excavator increases and the speed of end-effector becomes faster, which conventional controls have been unable to handle adequately. On the basis of modern robust controls we approached this problem by: adopting time-delay control (TDC) as the baseline control; and enhancing it with compensators on the basis of insights obtained from the plant dynamics. The resulting control law has been applied to straight-line motions of a 13 ton hydraulic excavator with the bucket (end-effector) speed of 0.5 m/sec, a speed level at which skilful operators work. The accuracy achieved was within 3 cm for surfaces with various inclinations and over broad ranges of joint motions, which is far better than that of an expert.
FootSpring: A Compliance Model for the ATHLETE Family of Robots (2010)

This paper describes and evaluates one method of modeling compliance in a wheel-on-leg walking robot. This method assumes that all of the robot s compliance takes place at the ground contact points, specifically the tires and legs, and that the rest of the robot is rigid. Optimization is used to solve for the displacement of the feet and of the center of gravity. This method was tested on both robots of the ATHLETE family, which have different compliance. For both robots, the model predicts the sag of points on the robot chassis with an average error of about one percent of the height of the robot.
Structural And Chemical Organization Of The Rat Interpeduncular Nucleus (1989)

The structural and chemical organization of the rat interpeduncular nucleus (IPN) was examined employing wheat germ agglutinin conjugated to horseradish peroxidase (WGA-HRP) and immunohistochemistry at the light and electron microscope level. The topographical and ultrastructural arrangements of habenular efferents innervating the IPN were studied using stereotaxic placements of WGA-HRP. The medial habenula provided a prominent afferent input to the many IPN subnuclei, with the lateral and rostral subnuclei receiving a predominantly ipsilateral input, and the intermediate, central and dorsomedial subnuclei receiving a symmetrical projection. Habenular terminals formed distinct axodendritic synapses in the rostral, lateral, intermediate and central subnuclei.;Projections of the fasciculus retroflexus (FR) were stained immunohistochemically for choline acetyltransferase (ChAT) or substance P (SP). These inputs were topographically organized among the IPN subnuclei, such that ChAT-positive axons innervated the rostral, intermediate and central subnuclei, and SP-positive inputs terminated in the lateral, dorsomedial and rostral subnuclei. Characteristic axodendritic synapses of the intermediate, central and rostral subnuclei were composed of ChAT-positive terminals, and those in the lateral, rostral and dorsomedial subnuclei were composed of SP-positive terminals.;A prominent population of neurons and an extensive plexus of axons and terminals stained immunohistochemically for glutamic acid decarboxylase (GAD) were present in the rostral, lateral, central and intermediate subnuclei. Axodendritic and axosomatic synapses possessing GAD immunoreactivity pre - and/or postsynaptically were evident in these subnuclei. GAD-immunoreactive dendrites in the intermediate, central and rostral subnuclei also received ChAT-positive terminals, and those in the lateral subnucleus received SF-positive terminals. SP-positive dendrites in the rostral subnucleus were also in receipt of ChAT-positive terminals.;The IPN is considered to be an important link between the septohabenular circuit of the limbic forebrain and several raphe and tegmental centres of the hindbrain. Neurons of the IPN are in receipt of descending habenular projections which provide putative excitatory inputs, as well as intrinsic, putative inhibitory inputs. The integration of habenular inputs with those arising from intrinsic sources may play an important role in the direct and transsynaptic modulation of projection neurons of the IPN which provide afferent inputs to the raphe and tegmental centres of the hindbrain.
The Synthesis of 6-Deazaformycin A (2009)

The synthesis of the new C-nucleoside 6-deazaformycin A was achieved through the condensation of a suitably substituted lithiated 2-picoline with 2,3,5-tri-O-benzyl-d-ribonolactone, borohydride reduction of the resulting hemiacetals, followed by intramolecular Mitsunobu cyclization of the carbinols, manipulation of the protecting groups, and subsequent ring closure to result in the formation of 7-amino-3-(β-d-ribofuranosyl)pyrazolo[4,3-b]pyridine.
Spreading the load: Antigen transfer between migratory and lymph node‐resident dendritic cells promotes T‐cell priming (2017)

Dendritic cells (DC) are specialized in the processing and presentation of antigen for the activation of lymphocytes. Multiple subsets of DCs exist with distinct functions and roles in the initiation of immune responses. DCs found within tissues acquire antigens or become infected by pathogens and migrate to local draining lymph nodes (LN) where they can directly stimulate T cells. These migratory DCs can also transfer antigens to LN-resident DCs and may indirectly enhance T cell priming. In this issue of the European Journal of Immunology, Gurevich et al. [Eur. J. Immunol. 2017. 47: 1802-1818] elegantly demonstrate the influence of the transfer of antigen from migratory DCs to resident DCs on the dynamics of CD8 T-cell priming in mice. Using both in vitro imaging to visualise antigen dissemination and intravital 2-photon microscopy to track T cell clustering with migratory and resident DCs, antigen-donor DC were found to efficiently distribute antigen to recipient DC. This process, which involved LFA-1, enhanced the recruitment of CD8<sup>+</sup> T cells into the response and rescued priming when DCs were impaired in presentation capacity. Together, these findings shed light on the dynamics of the transfer of antigens between DCs in vivo for the efficient priming of cytotoxic T cell responses.
