The effect of size distribution on photoluminescence of excited states from InAs/GaAs quantum dots (2005)

We have used the effective mass approximation to calculate the effect of size non-uniformity on the width of photoluminescence (PL) emission peaks of the quantum dots (QDs). In order to investigate the variation in PL inhomogeneity of the energy levels, we have calculated the effects of small changes of the structural parameters on the energy spectrum. Theoretical calculations have shown that different size distributions effect differently on the width of the ground and excited states of QD. The distribution of height, as well as the diameter and the volume, appears to be the key parameter that controls the effective potentials in the vertical and lateral directions, and these two potentials change the sharpness of all PL peaks. This causes the line width of the higher energy levels to be either broader or sharper than that of the ground state, or in certain cases to be equal to the line width of the ground state.
Rapid high resolution western blotting: from gel to image in a single day. (1992)

A streamlined protocol is described that allows high sensitivity antigen detection by Western blotting in a single day. The choice of membrane blotting matrix, as well as blocking reagents, has been optimized in order to allow rapid development of the blot with chemiluminescent reagents. The entire process, from gel to blot to a permanent, hard copy image on x-ray film, can be accomplished within six hours.
A Review of Completions and Gravel-Pack Techniques of the Xijiang Development (1997)

Summary The first gravel-packed completions have been run in the Pearl River mouth basin of the South China Sea in the Xijiang fields. The reservoirs in these fields are characterized by unconsolidated, friable, high-permeability sandstones, and, as such, presented many challenges. This paper addresses the development of these fields and how reservoir characteristics and parameters and unexpected deviations were experienced by the operator, as well as the impact these deviations had on completion designs. Important considerations included the need for sand control, zonal isolation, high-rate production, and reduced completion durations. Finally, the practical application and evaluation of pregravelpack stimulation techniques, gravel-pack carrier consideration, fluid-loss controls, and general completion procedures are presented, along with the innovative completion designs developed to manage these needs.

Mechanoresponsive Hydrogel Particles as a Platform for Three-Dimensional Force Sensing (2019)

We introduce a novel concept for mechanosensitive hydrogel microparticles, which translate deformation into changes in fluorescence and can thus function as mechanical probes. The hydrogel particles with controlled polymer network are produced via droplet microfluidics from poly(ethylene glycol) (PEG) precursors. Förster resonance energy transfer donors and acceptors are coupled to the PEG hydrogel network for reporting local deformations as fluorescence shifts. We show that global network deformations, which occur upon drying/rehydration, can be detected via a characteristic fluorescence shift. Combined characterization with confocal laser scanning microscopy and atomic force microscopy (AFM) shows that also local deformation of the particles can be detected. Using AFM, the mechanical properties of the particles can be quantified, which allows linking strain with stress and thus force sensing in a three-dimensional environment. Microfluidic material design allows for precisely varying the size of our hydrogel microparticles as well as their mechanical properties and polymer network structure with regard to the choice of the macromolecular precursors and their functionalization with fluorophores. Thus, concomitant changes in mechanical properties and mechanosensitivity qualify these hydrogel microparticles as an adjustable material platform for force sensing in structural mechanics or cell culturing.

Leveraging FrameNet to Improve Automatic Event Detection (2016)

Frames defined in FrameNet (FN) share highly similar structures with events in ACE event extraction program. An event in ACE is composed of an event trigger and a set of arguments. Analogously, a frame in FN is composed of a lexical unit and a set of frame elements, which play similar roles as triggers and arguments of ACE events respectively. Besides having similar structures, many frames in FN actually express certain types of events. The above observations motivate us to explore whether there exists a good mapping from frames to event-types and if it is possible to improve event detection by using FN. In this paper, we propose a global inference approach to detect events in FN. Further, based on the detected results, we analyze possible mappings from frames to event-types. Finally, we improve the performance of event detection and achieve a new state-of-the-art result by using the events automatically detected from FN.
Dynamics of coherently pumped lasers with linearly polarized pump and generated fields (1993)

The influence of light polarization on the dynamics of an optically pumped single-mode laser with a homogeneously broadened four-level medium is theoretically investigated in detail. Pump and laser fields with either parallel or crossed linear polarizations are considered, as are typical in far-infrared-laser experiments. Numerical simulations reveal dramatically different dynamic behaviors for these two polarization configurations. The analysis of the model equations allows us to find the physical origin of both behaviors. In particular, the crossed-polarization configuration is shown to be effective in decoupling the pump and laser fields, thus allowing for the appearance of Lorenz-type dynamics.
Locally Adaptive Sampling (2010)

In this paper, we introduce a class of Locally Adaptive Sampling schemes. In this sampling family, time intervals between samples can be computed by using a function of previously taken samples, called a sampling function. Hence, though it is a non-uniform sampling scheme, we do not need to keep sampling times. The aim of LAS is to have the average sampling rate and the reconstruction error satisfy some requirements. We propose four different schemes of LAS. The first two are designed for deterministic signals. First, we derive a Taylor Series Expansion (TSE) sampling function, which only assumes the third derivative of the signal is bounded, but requires no other specific knowledge of the signal. Then, a Discrete Time-Valued (DTV) sampling function is proposed, where the sampling time intervals are chosen from a lattice. Next, we consider stochastic signals. We propose two sampling methods based on linear prediction filters: a Generalized Linear Prediction (GLP) sampling function, and a Linear Prediction sampling function with Side Information (LPSI). In GLP method, we only assume the signal is locally stationary. However, LPSI is specifically designed for a known signal model.
Optimization-based reproduction of diffuse audio objects (2015)

The creation of a diffuse sound event from a single audio signal is an important signal processing task, for instance in spatial audio reproduction or audio coding. Current algorithms based on decorrelation filters or frequency-dependent panning typically cause artifacts due to transients or time-domain aliasing. In this paper, we propose an optimization-based approach to diffusion that creates a set of filters to approximate a desired distribution of frequency-dependent propagation directions to create the perception of a diffuse sound field with a multi-channel audio system. Thus, the diffusion can be optimally adapted to a specific reproduction scenario. In addition, the transient response can be purposefully improved by imposing constraints on the time-domain filter coefficients.
[Influence of different components of stored blood on the infectivity of Treponema pallidum (Nichols Strain) (author's transl)]. (1978)

A factor with killing effect at 35 degrees C on Treponema pallidum is shown to be in normal human serum. The activity of this factor is increased by the stabiliser of stored blood.--In the presence of the stabiliser T. pallidum loses its infectivity in human serum at 4 degrees C within 10 hours. The mechanism of the reaction is explained.--Finally it is discussed whether these observations may be helpful in the prevention of transfusion syphilis.
Aluminium Doping of 4H-SiC Grown with HexaMethylDiSilane (2005)

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
Improving the Acknowledgment Handling of SCTP (2010)

In general, the Stream Control Transmission Protocol (SCTP) delays the sending of acknowledgments. For specific cases, this results in non-optimal protocol behavior. Therefore, the protocol specification defines several exceptions that allow the receiver of an SCTP packet containing user data to send the corresponding acknowledgment without delaying it. However, all these exceptions only take the status at the user data receiver side into account and thus cannot cover all relevant situations. To overcome this limitation, the authors have proposed a generic mechanism allowing the sender of an SCTP packet containing user data to indicate, that the corresponding acknowledgment should not be delayed. This paper analyzes the benefits of using this sender side mechanism under several conditions.
Surface Plasmons on Metal Nanoparticles:  The Influence of Shape and Physical Environment (2007)

The surface plasmon response of metal nanoparticles is studied for different shapes and physical environments. For polyhedral nanoparticles, the surface plasmon resonances are studied as a function of the number of faces and vertices. The modification of these surface plasmons by different surrounding media and the presence of a substrate or other nanoparticles is also discussed. We found that polyhedral nanoparticles composed with less faces show more surface plasmon resonances, and as the nanoparticle becomes more symmetric, the main surface plasmon resonance is blue-shifted. It is also found that the corners induce more surface plasmons in a wider energy range. In the presence of a substrate, multipolar plasmon resonances are induced, and as the nanoparticle approaches the substrate, such resonances are red-shifted. The interaction among nanoparticles also induces multipolar resonances, but they can be red or blue-shifted depending on the polarization of the external field.
A newly synthesized nitrogen‐rich derivative of bicyclic quinoxaline—Structural and conceptual DFT reactivity study (2020)

Abstract Novel nitrogen‐rich compound featured bicyclic quinoxaline as a basic core structure has been synthesized, 1‐{[1‐(3‐azido‐2‐hydroxypropyl)‐1 H ‐1,2,3‐triazol‐4‐yl]methyl}‐3‐methyl‐1,2‐dihydroquinoxalin‐2‐one with formula C 15 H 16 N 8 O 2 , and their structural and chemical reactivity aspects have been comprehensively discussed. Nature, role, and relative contribution of weak noncovalent interactions in supramolecular assembly have been assessed through single‐crystal analysis and computational approaches. Useful information about the global and local reactivity were obtained from Conceptual Density Functional Theory at wB97X‐D/cc‐pVDZ level. Studied system could act as strong electrophile and/or moderate nucleophile in polar organic reactions. We hope this study will provide deeper insight in the knowledge of the synthesis and chemistry of the quinoxaline and quinoxaline derivatives.

Gene therapy using genome‐edited iPS cells for targeting malignant glioma (2022)

Glioblastoma is characterized by diffuse infiltration into the normal brain. Invasive glioma stem cells (GSCs) are an underlying cause of treatment failure. Despite the use of multimodal therapies, the prognosis remains dismal. New therapeutic approach targeting invasive GSCs is required. Here, we show that neural stem cells (NSCs) derived from CRISRP/Cas9-edited human-induced pluripotent stem cell (hiPSC) expressing a suicide gene had higher tumor-trophic migratory capacity compared with mesenchymal stem cells (MSCs), leading to marked in vivo antitumor effects. High migratory capacity in iPSC-NSCs was related to self-repulsive action and pathotropism involved in EphB-ephrinB and CXCL12-CXCR4 signaling. The gene insertion to <i>ACTB</i> provided higher and stable transgene expression than other common insertion sites, such as <i>GAPDH</i> or <i>AAVS1</i>. Ferroptosis was associated with enhanced antitumor immune responses. The thymidylate synthase and dihydroprimidine dehydrogenase expressions predicted the treatment efficacy of therapeutic hiPSC-NSCs. Our results indicate the potential benefit of genome-edited iPS cells based gene therapy for invasive GSCs. Furthermore, the present research concept may become a platform to promote clinical studies using hiPSC.
Spatial Distributions of Individual Traps in a Si/SiO2 Interface (1996)

We have investigated individual traps in the Si/SiO 2 interface by observing random telegraph signals (RTSs). The traps having energy levels within a few k B T of the Fermi level can capture or emit single electrons, and become sources of RTSs. We report the first investigation of spatial distributions of single-carrier traps in a MOSFET with a double gate structure. We observe RTSs with changing bias voltages on two lower gates, and show that their variations describe the spatial distributions of the individual traps.

The Presence of Lys27 Instead of Asn27 in Human Phospholamban Promotes Sarcoplasmic Reticulum Ca 2+ -ATPase Superinhibition and Cardiac Remodeling (2006)

Human PLN may play a more inhibitory role than that of other species in Ca2+ cycling. Expression of human PLN in the mouse is compensated by alterations in Ca2+-handling proteins and cardiac remodeling in an effort to normalize cardiac contractility. Thus, the unique amino acid sequence of human PLN may be critical in maintaining a high cardiac reserve, which is of paramount importance in the regulation of human cardiac function.
Photon migration in turbid media: a finite-element solution for the most favorable path (2002)

A better understanding of the fundamental principles of photon migration in highly scattering media is of great importance for developing new methods for disease diagnosis, imaging, and tomography. In this paper we present a most-favorable-path approach to the problem of light propagation in turbid media, based on the diffusion equation. The most favorable path, on which photons will be found, can be obtained from the path of the net flux propagation. The diffusion intensity and the direction of the net flux can be calculated with the finite-element method, which can deal with heterogeneous problems and frequency-domain problems within complex geometry, and can introduce boundary effects as well. Simulations were conducted for phantoms with different optical parameters and source-detector separations. Experiments have been performed to verify this new method. The most favorable path is found to be more sensitive to the source-detector separation and the absorption coefficient of the medium than to the scattering coefficient. The feasibility of using the theory in optical tomography for the recognition of objects hidden in turbid media is discussed.
Cytokines alter production of HIV-1 from primary mononuclear phagocytes (1988)

Some strains of human immunodeficiency virus type 1 (HIV-1) can infect primary monocytes and monocyte-derived macrophages in vitro. In this report, the effect of cytokines on the production of one of these strains that shows a tropism for mononuclear phagocytes, designated HIV-1JR-FL, was studied. Primary peripheral blood mononuclear phagocytes infected with HIV-1JR-FL were treated with the hematopoietic factors: granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-3 (IL-3), macrophage colony-stimulating factor (M-CSF), and gamma-interferon (gamma-IFN). The M-CSF, GM-CSF, IL-3, and gamma-IFN were able to alter HIV-1 production under different conditions.

Abstract This paper presents an experimental study of linear unsteady state gas flow through a low permeability porous medium. Results of a series of controlled tests indicate that a steady state approximation technique for the solution of linear unsteady state gas flow is the most accurate and convenient method. s tests confirm the validity of using finite difference equations for solving the nonlinear partial differential equation for the unsteady state gas flow. Also the results these tests indicate that the modified solution of the partial differential equation relating slightly compressible fluid flow does not represent gas flow in a low permeability porous medium. Introduction The investigation of unsteady state gas flow has been restricted almost entirely to mathematical analysis. Basically, there are three types of solutions which approximate gas flow: The first method is a modified solution of the differential equation representing slightly compressible fluid flow. Certain critical assumptions are used to force the liquid solutions to exemplify gas flow. For the second type of solution, finite difference equations are used to represent and solve the non-linear partial differential equation for gas flow. The most recent analysis of transient gas flow involves forcing the steady state flow equation for gas to predict pressure decay with time. Since all three types of analyses are not true solutions to the differential equation relating gas flow in porous media, they are restricted to certain limiting assumptions and methods of calculation. For example, method number one has the limitation that small pressure drawdowns must occur in the reservoir. In the case of low permeability formations, this is almost an impossibility.
Scattering from optical surfaces and coatings: an easy investigation of microroughness (1990)

We show how the anisotropy of scattering enables to point out the origin of microroughness in optical coatings with no ambiguity. Experimental results prove that residual roughness due to material microstructure is negligible with coatings produced by Ion Assisted or Ion Plating deposition. In these conditions, and provided that the substrate is measured before coating, prediction of scattering from a stack of any design requires the knowledge of only two cut-off frequencies that describe the action of materials at interfaces. These parameters can be determined with single layers and then can be used for more complex optical systems. Since isotropy degree variation of scattering does not depend on the design of the coating, it enables to show that the differences that can occur between calculation and measurements are due to thickness or index errors on the layers. Therefore the substrate roughness plays a primordial role and we compare, using numerical calculation, the roughness spectra that can be obtained with mechanical or optical measurements.
Pipelined van Emde Boas Tree: Algorithms, Analysis, and Applications (2007)

Priority queues are essential for various network processing applications, including per-flow queueing with quality-of-service (QoS) guarantees, management of large fast packet buffers, and management of statistics counters. In this paper, we propose a new data structure for implementing high-performance priority queues based on a pipelined version of the van Emde Boas tree. We show that we can achieve O(1) amortized time operations using our architecture, but we can achieve this algorithmic efficiency using only O (log log u) number of pipelined stages, where u is the size of the universe used to represent the priority keys.
Optic disc shape in patients with long-lasting unilateral esotropia and exotropia (2019)

Optic disc ovality did not differ markedly among long-lasting esotropic eyes, exotropic eyes, and non-strabismic eyes. It suggests that optic disc shape may not be markedly influenced in non-highly myopic eyes by a potential backward pull of the optic nerve on the optic disc structures in adduction or abduction.
