Realization of sensitized erbium luminescence in Si–nanocrystal composites obtained from solution processable sol–gel derived materials (2010)

Silicon nanocrystals embedded in a silica matrix are good sensitizers of erbium ion photoemission and have application in photonic devices. We have developed a unique synthetic method to produce gram quantities of silicon nanocrystals embedded in a silica matrix containing erbium ions from solution borne precursors. This realization has facilitated a thorough study of the influence of erbium precursor on the chemical, physical and optical properties of the resulting materials. Three erbium precursors, erbium chloride, erbium tris(bis(trimethyl)silyl)amide, and erbium octanoate, were studied using Scanning Electron Microscopy, Energy Dispersive X-Ray Spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and Photoluminescence Spectroscopy. It has been determined that the rare earth complexing ligand dramatically influences the erbium distribution homogeneity, solution processability, physical properties, and optical response. Most importantly we conclusively demonstrate that the optically active erbium ions in the resulting composites reside in the oxide matrix and not within the nanocrystals.
Holographic-grating-based optical-controlled true-time-delay devices (2004)

The holographic-grating based wavelength-controlled true-time-delay devices are presented in the paper. The optical true-time-delay can be continuously controlled by continuously tuning the wavelength of a single laser within the devices. The dispersion ability of the devices is greatly enhanced by increasing the diffraction angles of the holographic gratings. The fabricated true-time-delay devices work within 1550nm region. The loss performance of the devices were calculated and measured. The wavelength-controlled true-time-delay was also characterized both theoretically and experimentally.
Understanding Purchase Behaviors through Personality-driven Traces (2017)

We present a computational approach to understanding users' purchase behavior through personality analytics. We model purchase behavior as interactions between personality traits, consumption preferences and product attributes, and represent such interactions as digital traces. We model all possible digital traces using a likelihood trace graph, and determine the likelihood of an edge based on the associations between adjacent pairs of personality attributes, consumption preferences, and product attributes, respectively. In our approach, users' personality traits are inferred from their written texts, and are correlated to a canonical set of consumption preferences. The consumption preferences are then mapped to product descriptions based on their semantic similarity. We demonstrate the effectiveness and usefulness of our approach through a case study on a real-world purchase data.
Temporal and polarization dependence of the nonlinear optical response of solvents (2018)

It has long been known that nonlinear refraction in solvents can depend on pulse width, and this along with experimental uncertainties has led to orders-of-magnitude disagreements in nonlinear refractive coefficients reported in the literature. To resolve this issue, we perform beam-deflection (BD) measurements of the rigorously defined nonlinear impulse response function for 24 commonly used solvents selected from various classes of molecules. Using this polari-zation-resolved BD, the bound-electronic and the three major nuclear contributions are separately measured by determining the magnitudes, symmetry, and temporal dynamics of each mechanism. This allows us to construct the response functions that we use to accurately establish self-consistent references for predicting and interpreting the outcomes of other experiments performed on these materials over the temporal range from 10 fs to 1 ns. The results also provide insight into relating solvent nonlinearities with their molecular structures and exploring the effects of the Lorentz–Lorenz local field. We find that nonconjugated molecules with small polarizability anisotropy exhibit negligible reorientational response, and hence the nonlinear refraction is almost independent of pulse width. Knowledge of the response functions also allows engineering the transient nonlinear refractive properties of solutions of organic dyes, for example, materials with effectively zero nonlinear refraction.
Subsea Fiber Topology and Effect on 3D and 4D Subsea DAS VSP Images (2021)

Summary Distributed acoustic sensing (DAS) is a rapidly evolving, conveyance-agnostic technology for both seismic and reservoir diagnostic applications. Despite maturity in dry-tree and retrievable applications, there are significant challenges associated with DAS for subsea applications. While fiber optic engineers understand the complexities and subtleties of the sources of optical losses and their respective hardware compensations, very little has been provided to help geoscientists understand the impact of the net signal-to-noise (SNR) impacts on vertical seismic profile (VSP) data, and its 3D and 4D answer products. This is particularly critical to quantify as time-lapse VSP is a primary basis of design for subsea DAS. This paper enumerates the sources of subsea optical signal losses and their respective compensations in different subsea sensing configurations, and then demonstrates their systems-level SNR effects on 3D and 4D VSP imaging relative to the dry-tree base case that geoscientists are familiar with today.
Multiple mechanisms of resistance to cis-diamminedichloroplatinum(II) in murine leukemia L1210 cells. (1987)

As an experimental model for resistance to cis-diamminedichloroplatinum(II) (cis-DDP), murine leukemia L1210 cells have been exposed to a stepwise increase in cis-DDP concentration to produce a variety of resistant cell lines. Intraspecies hybrids of the sensitive and resistant cells were made to determine whether cis-DDP resistance is a dominant or recessive trait. Hybrid cells displayed a partial degree of resistance as compared to the parental cells. To determine whether this was due to a single codominant trait or contribution from a variety of resistance mechanisms, the cells and hybrids were investigated for alterations in the accumulation of drug, as well as alterations in glutathione levels which might inactivate the drug. The cis-DDP-resistant cells demonstrated both a 50% reduction in accumulation of drug and a 1.7-fold increase in intracellular glutathione. Reducing the glutathione levels in these cells with buthionine sulfoximine did not sensitize them to cis-DDP. The hybrid cells had the same accumulation and the same levels of glutathione as the cis-DDP-sensitive cells. Parallel studies were performed with cells resistant to 1,2-diaminocyclohexaneplatinum(II) analogues. These cells also demonstrated reduced drug accumulation but no increase in glutathione. Therefore, both a decrease in accumulation and increase in glutathione may mediate resistance. Both mechanisms represent recessive traits as demonstrated in the cell hybrids. These mechanisms can only account for a small part of the resistance in these cells. A major, dominant mechanism occurs after the DNA has been platinated, but it remains to be determined whether this involves DNA repair, postreplication repair, or some other as yet unidentified process.
Large beam coupling gain in lnP:Fe using Franz–Keldysh electrorefractive photorefraction (1990)

A beam-coupling gain of 19.1 cm −1 in InP:Fe has been achieved using near band edge photorefractive techniques. The conventional electro-optic photorefractive (EOPR) effect in semiconductors may be combined with the Franz–Keldysh electrorefractive photorefractive (ERPR) effect to produce large beam coupling gain coefficients. We have examined the effects using a tuneable Ti:sapphire laser in a pump/probe configuration and an applied electric field. Conventional EOPR creates a sinusoidal space-charge field (Esc) through carrier drift and diffusion, and the applied field (E dc ) increases the magnitude of the applied space charge (E tot = E sc + E dc ), as well as affecting the phase shift of Δn with respect to the intensity pattern. With appropriate temperature stabilization and ERPR, this phase shift can be maintained near ±90°, depending on the sign of E dc , determining the direction of energy transfer. We have characterized beam coupling gain, Γ, as a function of wavelength, intensity, temperature, grating spacing, and applied electric field and achieved a maximum Γ = 19.1 cm −1 at λ = 970 nm, T = 17 °C, Λ (grating wavelength) = 8.5 μ m, I Pump = 141 mW/cm 2 , and β (pump/probe ratio) ≈ 1000. Still higher gains have been seen using a moving grating technique, and the results will be presented at the conference.
Heat shock proteins in immune response (2003)

The connection between HSPs and tumor rejection antigens became apparent through tumor rejection studies in mice and rats. In search for individually distinct tumor rejection antigens, tumor cell lysates were fractionated biochemically and each fraction was tested for its ability to immunize in vivo against the tumor. The tumor rejection antigens thus found were mostly HSPs (Tab. 1). Preparations of HSPs, e.g., HSP70, HSP90, gp96 and calreticulin (CRT) from Meth A fibrosarcoma (tumor induced in BALB/c mice by methylcholanthrene) when used to immunize BALB/c mice, rendered the mice immune to subsequent challenge with live Meth A tumor cells in a classical tumor rejection assay [1-3]. However, immunization of mice with HSP preparations from normal tissues [2] or from antigenically-distinct tumor cells [1, 4] did not protect the animals against tumor challenge.
Tick-borne encephalitis (TBE) in a 6 week old infant (2004)

Case report: A 6-week-old girl developed fever, irritability, meningeal signs with bulging fontanelle and a partial, secondary-generalized seizure. CSF yielded pleocytosis (172 lymphocytes, 81 mono-cytes/ul) and elevated protein (0,83g/l), cranial MRI showed encephalitic signs in both frontal and parietal lobes. Because of a tick bite in an endemic area 10 days before admission, ELISA-IgG and IgM to TBE-virus were sought and found in serum, whereas Borrelia burgdorferi serology, Herpes-simplex virus PCR and bacterial CSF-culture were negative. Phenobarbitone was administered because of repetitive seizures, while the EEG showed series of sharp waves in the right parieto-temporal region. She consecutively became seizure free. At first follow-up after 6 weeks she demonstrated pathologic neurological signs with increased muscular tone, hyperreflexia, fidgety movements, and EEG showed slow waves in the right parieto-temporal region.

Automated Wavelength Recovery for Microring Resonators (2012)

We lock an adiabatic microring resonator to a laser line with a lock-in time of 200µs using a digital control loop, thereby experimentally demonstrating the first automated and scalable wavelength recovery approach for microring resonators.
Multi-modal & Multi-view & Interactive Benchmark Dataset for Human Action Recognition (2015)

Human action recognition is one of the most active research areas in both computer vision and machine learning communities. Several methods for human action recognition have been proposed in the literature and promising results have been achieved on the popular datasets. However, the comparison of existing methods is often limited given the different datasets, experimental settings, feature representations, and so on. In particularly, there are no human action dataset that allow concurrent analysis on three popular scenarios, namely single view, cross view, and cross domain. In this paper, we introduce a Multi-modal & Multi-view & Interactive (M2I) dataset, which is designed for the evaluation of the performances of human action recognition under multi-view scenario. This dataset consists of 1760 action samples, including 9 person-person interaction actions and 13 person-object interaction actions. Moreover, we respectively evaluate three representative methods for the single-view, cross-view, and cross domain human action recognition on this dataset with the proposed evaluation protocol. It is experimentally demonstrated that this dataset is extremely challenging due to large intraclass variation, multiple similar actions, significant view difference. This benchmark can provide solid basis for the evaluation of this task and will benefit advancing related computer vision and machine learning research topics.

As-grown superconducting Bi2Si2Ca2Cu3Ox thin films with T czero of 102 K prepared by rf magnetron sputtering (1994)

As-grown high-quality superconducting thin films of the Bi2Sr2Ca2Cu3Ox were prepared by rf magnetron sputtering with a regulated shuttering technique. 2223 phase films with a 2201 phase buffer layer were deposited on MgO(100) substrates under rigorous control of the film composition, especially of bismuth contents. As a source of bismuth a sufficiently presputtered Bi2O3 target was used. At the preparation, Bi-Sr-Cu-O and Ca-Cu-O blocks were deposited alternately, no post-treatment steps were performed. The zero resistivity critical temperature of the as-grown film was 102.5 K and the critical current density at 4.2 K was 1.5×107 A/cm2. The growth rate was about 360 Å/h.
3P1-R01 Joint angle control of the robot hand with pneumatic actuator(Robot Hand Mechanism and Grasping Strategy (1)) (2014)

Currently, reduction of the population beginning in Japan, declining labor force is threatened. Factory automation, and the like as a solution to this problem in the industrial field. Material handling technology is one prime example. However, work performance due to the current robot can not be said to be too high. So, we made a study of the robot arm end effector as a highly versatile, with a robot hand of five fingers in this study. Nonlinearity and hysteresis are present in the pneumatic artificial manipulator is a driving source, it is difficult to control. In the middle finger joint angles of the hand unit, we have verified the effectiveness of the joint angle controller.
A new accurate (time-independent) method for treating three-dimensional reactive collisions: The application of optical potentials and projection operators (1990)

This work describes a new (time-independent) approach to the study of atom–diatom reactive collisions in three dimensions. The method is based on the idea of converting a reactive multiarrangement problem into an inelastic single-arrangement problem. This conversion is done by applying optical potentials which are located at all exits of the reagents arrangement. The reactive transition probabilities are calculated applying flux formulas. The method is reminiscent of a previous time-dependent method successfully applied for both collinear and three-dimensional reactive collisions.
A Highly Reliable SRAM PUF with a Capacitive Preselection Mechanism and pre-ECC BER of 7.4E-10 (2019)

An SRAM PUF with an internal error reduction mechanism is presented. A capacitive preselection test identifies potentially unstable cells with insufficient mismatch. The test can be accomplished in one VDD / temperature corner. An implementation in TSMC 65nm technology disqualified all the unstable cells (19.7%) in 14 800-bit arrays. The test has no impact on the randomness of the PUF and negligible impact on area. A highly competitive pre-ECC BER of 7.4E-10 and an energy consumption of 16fJ/bit were achieved.
Profile Estimation of High-Concentration Arsenic Diffusions in Silicon (1972)

In order to facilitate surface concentration estimation for arsenic diffusion, a simple expression has been derived which is dependent only upon the junction depth xJ and the sheet resistance Rs: Cs = 1.56 × 1017/xJRs. This equation was derived from experimental mobility data and a polynomial approximation to the solution of the arsenic diffusion equation. Available data on diffusions carried out from five different kinds of arsenic sources indicate that this derived equation for Cs is accurate to within 15% for Cs≳ni.
Activation of the dopamine 1 and dopamine 5 receptors increase skeletal muscle mass and force production under non-atrophying and atrophying conditions (2011)

These data demonstrate for the first time that treatment with a dopamine 1/5 receptor agonist results in (1) significant preservation of EDL, TA, MG and soleus muscle mass and EDL muscle force production during periods of atrophy and (2) hypertrophy of TA and MG muscle. These effects appear to be mainly mediated by both the dopamine 1 and dopamine 5 receptors.
Flexoelectricity in an oxadiazole bent-core nematic liquid crystal (2014)

We have determined experimentally the magnitude of the difference in the splay and bend flexoelectric coefficients, |e1 − e3|, of an oxadiazole bent-core liquid crystal by measuring the critical voltage for the formation of flexodomains together with their wave number. The coefficient |e1 − e3| is found to be a factor of 2–3 times higher than in most conventional calamitic nematic liquid crystals, varying from 8 pCm−1 to 20 pCm−1 across the ∼60 K—wide nematic regime. We have also calculated the individual flexoelectric coefficients e1 and e3, with the dipolar and quadrupolar contributions of the bent-core liquid crystal by combining density functional theory calculations with a molecular field approach and atomistic modelling. Interestingly, the magnitude of the bend flexoelectric coefficient is found to be rather small, in contrast to common expectations for bent-core molecules. The calculations are in excellent agreement with the experimental values, offering an insight into how molecular parameters contribute to the flexoelectric coefficients and illustrating a huge potential for the prediction of flexoelectric behaviour in bent-core liquid crystals.

Neutralizing antibody responses to SARS-CoV-2 variants in vaccinated Ontario long-term care home residents and workers (2021)

Abstract Prioritizing Ontario’s long-term care home (LTCH) residents for vaccination against severe acute respiratory syndrome coronavirus 2 has drastically reduced their disease burden; however, recent LTCH outbreaks of variants of concern (VOCs) have raised questions regarding their immune responses. In 198 residents, mRNA vaccine dose 1 elicited partial spike and receptor binding domain antibody responses, while the second elicited a response at least equivalent to convalescent individuals in most residents. Residents administered mRNA-1273 (Moderna) mounted stronger total and neutralizing antibody responses than those administered BNT162b2 (Pfizer-BioNTech). Two to four weeks after dose 2, residents ( n = 119, median age 88) produced 4.8–6.3-fold fewer neutralizing antibodies than staff ( n = 78; median age 47) against wild-type (with D614G) pseudotyped lentivirus, and residents administered BNT162b2 produced 3.89-fold fewer neutralizing antibodies than those who received mRNA-1273. These effects were exacerbated upon serum challenge with pseudotyped VOC spike, with up to 7.94-fold reductions in B.1.351 (Beta) neutralization. Cumulatively, weaker vaccine stimulation, age/comorbidities, and the VOC produced an ∼130-fold reduction in apparent neutralization titers in LTCH residents and 37.9% of BNT162b2-vaccinated residents had undetectable neutralizing antibodies to B.1.351. Continued immune response surveillance and additional vaccine doses may be required in this population with known vulnerabilities.
A novel topology of high-speed SRM for high-performance traction applications (2018)

A novel topology of high-speed Switched Reluctance Machine (SRM) for high-performance traction applications is presented in this article. The target application, a Hybrid Electric Vehicle (HEV) in the sport segment poses very demanding specifications on the power and torque density of the electric traction machine. After evaluating multiple alternatives, the topology proposed is a 2-phase axial flux machine featuring both segmented twin rotors and a segmented stator core. Electromagnetic, thermal and mechanical models of the proposed topology are developed and subsequently integrated in an overall optimisation algorithm in order to find the optimal geometry for the application. Special focus is laid on the thermal management of the machine, due to the tough thermal conditions resulting from the high frequency, high current and highly saturated operation. Some experimental results are also included in order to validate the modelling and simulation results.
Prevalence of Regional Myocardial Thinning and Relationship With Myocardial Scarring in Patients With Coronary Artery Disease (2013)

Among patients with CAD referred for CMR and found to have regional wall thinning, limited scar burden was present in 18% and was associated with improved contractility and resolution of wall thinning after revascularization. These findings, which are not consistent with common assumptions, warrant further investigation.
