Recently, it has been reported that doped semiconductor nanoparticles can yield both high luminescence efficiencies and a spectacular lifetime shortening, which suggests that doped semiconductor nanoparticles form a new class of luminescent materials for various applications. From lifetime measurements and time-resolved spectroscopy we conclude that the ${\mathrm{Mn}}^{2+}$ emission does not show a spectacular shortening of the decay time upon decreasing particle size as reported earlier. The luminescence of nanocrystalline ${\mathrm{Z}\mathrm{n}\mathrm{S}:\mathrm{M}\mathrm{n}}^{2+}$ indeed has a short decay time (\ensuremath{\sim}100 ns), but also shows a long ms range decay time. The short decay time is ascribed to a defect-related emission of ZnS, and is not from the decay of the ${}^{4}{\mathrm{T}}_{1}{\ensuremath{-}}^{6}{\mathrm{A}}_{1}$ transition of the ${\mathrm{Mn}}^{2+}$ impurity as suggested by other authors. The ${}^{4}{\mathrm{T}}_{1}{\ensuremath{-}}^{6}{\mathrm{A}}_{1}$ transition of the ${\mathrm{Mn}}^{2+}$ has a ``normal'' decay of about 1.9 ms. Based on our observations, we conclude that doped semiconductor nanoparticles do not form a new class of luminescent materials, combining a high efficiency with a short (ns) decay time.
Short focal length concentrating photovoltaic collector (1988)

The design and prototype production of a short focal length concentrator are presented. The cost benefits, objectives, and system design for the concentrators are discussed in detail. The design results in a production-cost reduction because it allows the concentrator to be produced with full-automation techniques and uses far less nonPV material than is used for standard concentrators. 12% module efficiencies were obtained using a standard one-sun cell at 30:1 concentration. Costs are less than a dollar per watt for the module.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
One-step fabrication of organic nanoparticles as scattering media for extracting substrate waveguide light from organic light-emitting diodes (2012)

Tetraphenylethene (TPE) nanoparticles have been easily obtained by one-step vacuum sublimation the TPE powder. The TPE molecules crystallize themselves in room temperature which is probably due to their extremely low glass transition temperature. The as-deposited TPE nanoparticles scatter light effectively. By employing the TPE nanoparticles as scattering media for extracting the substrate waveguide light from blue organic light-emitting diodes (OLEDs), a 28% efficiency improvement has been obtained. By further co-evaporating the TPE and its derivative 4-(4-(1,2,2-triphenylvinyl)phenyl)-7-(5-(4-(1,2,2-triphenylvinyl)phenyl)thiophen-2-yl)benzo[c][1,2,5]thiadiazole (BTPETTD) as a color conversion and light scattering layer for the blue OLEDs, the blue-to-white photon conversion efficiency of the resultant white OLEDs has been enhanced from 52.7% to 70.1%, representing a 33% improvement. The vacuum sublimed TPE nanoparticles can find a wide variety of applications in optoelectronic devices such as solar cells and LEDs.
Aggregation-Enhanced Raman Scattering of a Cyanine Dye in Homogeneous Solution (1997)

We have conducted Raman investigations on the cyanine dye 3,3‘-dimethyl-9-phenyl-4,5:4‘,5‘-dinaphthothiacarbocyanine (NTC) for which an enhanced Raman scattering occurs that is concomitant with the formation of aggregates, and for which resonance Raman and surface-enhanced Raman scattering can be excluded. The formation of aggregated molecules is determined through characteristic changes in absorption and fluorescence spectra. Also, fluorescence lifetime measurements for monomeric and aggregated NTC are reported and independently confirm aggregate formation. Off-resonance Raman measurements for NTC in various physical states confirm that molecular aggregation leads to an enhancement of Raman scattering of vibrational modes of the monomeric species (i.e., intramolecular modes) and an even greater relative enhancement of certain modes of the molecules involved more intimately with formation of the aggregate (i.e., intermolecular modes). Additionally, we make empirical band assignments for NTC from which we are able to exclude structural distortion due to intermolecular interaction as the source for Raman band intensity enhancement.
Human Placental Derived Mesenchymal Stromal Cells (MSC) Grown in 3D-Culture (PLX-I), Promotes Engraftment of Human Umbilical Cord Blood (hUCB) Derived CD34+ Cells in NOD/SCID Mice. (2007)

Abstract The use of UCB for transplantation in adults is limited due to the low cell number in each unit. Engraftment rates are lower and the time for neutrophil and platelet recovery is longer following CBT compared to bone marrow (BM) transplants. Co-transplantation of human hematopoietic stem/progenitor cells (HSC) with mesenchymal stromal cells in an irradiated NOD/SCID mice model has been demonstrated to promote HSC engraftment. Using PluriX technology, we expanded human placental derived MSC on 3D-carriers in a bioreactor (PLX-I) and evaluated its potential to promote UCB engraftment in the NOD/SCID mice model. Flow cytometer analysis detected high rates of expression of CD105, CD73, CD90 and CD29 and lacked expression of CD45, CD34 and CD19 surface markers in the PLX-I cells. PLX-I cells were capable of differentiation into bone, adipose tissue and cartilage under specific inductive conditions. Additionally, they possess both immune privileged and immune suppressive characteristics in a mixed lymphocyte reaction (MLR) assay. In this study 60 – 100x103 hUCB derived CD34+ cells were injected into the tail vein of 7–8 week old NOD/SCID mice along with 0.5x106 PLX-I cells. Human cell engraftment was tested in both sublethally irradiated (350 rad) and chemotherapy (50 mg/kg busulfan) treated NOD/SCID mice. Following 5–6 weeks, mice BM FACS analysis showed a significant increase in % hCD45+ rate in mice transplanted with PLX-I cells compared to mice transplanted with CD34+ cells alone: 13.6 vs. 31.7, p=0.01, (n=6) in the irradiation setting and 28.8 vs 6.3, p<0.05 (n=7) in the chemotherapy setting. These preclinical results demonstrate the potential of human placental-derived MSCs, grown as a 3D culture (PLX-I), to promote hUCB CD34+ cell engraftment in BM. Co-transplantation of PLX-I may be considered for improving the delayed engraftment using CB as the source of HSC.
Maximum Power Point Tracking for Wind Turbine Using Integrated Generator–Rectifier Systems (2020)

Offshore wind is a rapidly growing renewable energy resource. Harvesting offshore energy requires multimegawatt wind turbines and high efficiency, high power density, and reliable power conversion systems to achieve a competitive levelized cost of electricity. An integrated system utilizing one active and multiple passive rectifiers with a multiport permanent magnet synchronous generator is a promising alternative for an electromechanical power conversion system. Deployment of the integrated systems in offshore wind energy requires maximum power point tracking (MPPT) capability, which is challenging due to the presence of numerous uncontrolled passive rectifiers. This article shows feasibility of MPPT based on a finding that the active-rectifier d-axis current can control the total system output power. The MPPT capability opens up opportunities for the integrated systems in offshore wind applications.
Non-thermal microwave effects on protein dynamics? An X-ray diffraction study on tetragonal lysozyme crystals (2005)

X-ray diffraction (XRD) was used to investigate the structural and dynamical effects of microwave fields on tetragonal single crystals of hen egg-white lysozyme at a resolution of 2.0 A. Using a modified slab-line waveguide allows on-line XRD to be carried out while the protein crystal is exposed to well defined microwave fields. High microwave power levels mainly lead to increased, but largely recoverable, lattice defects owing to the evaporation of crystal water. At lower microwave power levels, the presence of the microwave field results in localized reproducible changes in the mean-square displacements (B factors). At particular sites, it is found that the B factors even decrease with increasing microwave power. Most of these effects can be explained by a comparison of the data obtained under microwave irradiation with data obtained at elevated temperature which simulate heating owing to microwave absorption by unbound crystal water. The data show no indication of large microwave-driven displacements of structural subunits in the protein that would be expected if microwaves were to be absorbed resonantly by protein vibrations. Rather, the observed changes in the atomic mean-square displacements suggest that if microwaves couple non-thermally to globular proteins at hydration levels at which they still function, their effect on protein dynamics and structure is very small.
Automatic detection of cardiac cycle based on an adaptive time-frequency analysis of the phonocardiogram (2002)

Demonstrates the feasibility of an adaptive time-frequency analysis, the matching pursuit method, to detect each cardiac cycle of the phonocardiogram (PCG). The proposed new method combines a global search of the PCG in terms of energy distribution of the most important components with a local search according to the specific events found within a cardiac cycle. In the PCG recordings of twenty five patients, a detection rate of 96% was achieved. By eliminating the need for the recording of the electrocardiogram as the time-reference signal, this method reduces hardware and software overheads when analysis of PCG signals is primarily aimed. It is believed that, with minor modifications, this method can also be applied to extract different events of the PCG within a cardiac cycle. Furthermore, the procedure described in this paper can be applied to other kind of biomedical signals in order to extract coherent structures and identify specific events.
[The antioxidative activity of drugs in the liver microsomal system of rats]. (1991)

The antioxidative properties of drugs--diethylcarbamazine citrate--DECC, dipyridamole-DP, levamisole and labinzarit--have been investigated in various microsomal lipid peroxidation (LPO) models: NADPH-, ascorbate- and CCl4-dependent. The most strong antioxidant of direct action turned out to be DP, DECC exhibited the antioxidative properties as a result of metabolic activity in monooxygenases system of rat liver microsomes. Levamisole and labinzarit turned out to be weak antioxidants. The control of microsomal membrane stability against Fe(2+)-ADP, NADPH-induced LPO, after being isolated from rat liver after the action of CCl4 without and with DECC, showed that DECC protected microsomal membranes from CCl4 in vivo and they remained stable against LPO in vitro.
Pharmacologically activated migration of aortic endothelial cells is mediated through p38 SAPK (2002)

Impairment in endothelial cell (EC) function plays a central role in vascular diseases (e.g. atherosclerosis, restenosis, diabetic angiopathies, microvascular angina, peripheral arterial disease). BRX-235 (a novel small molecule synthesized by Biorex, Hungary) has a potent vasculoprotective activity in different in vivo and in vitro studies. Since the importance of the p38 pathway in EC homeostasis and migration in particular is well documented, we have carried out studies to address the role of the p38 stress activated protein kinase (p38 SAPK) in the mode of action of BRX-235. In this study, Bovine aortic endothelial cells were used in a wounding migration assay (WMA) and for Western-blot analysis to study the effect and molecular mechanism of BRX-235-induced EC migration. The bovine aortic endothelial (BAE) cells were shown to be good models for EC migration. Both endothelial cell growth factor (ECGF)- and BRX-235-induced BAE cell migration were shown to be inhibited by SB 203580, a specific inhibitor of p38 SAPK. It was also shown that, BRX-235 induces phosphorylation of p38 SAPK without affecting p38 SAPK protein levels. Thus, BRX-235 acts upstream of p38 SAPK. In summary, we have shown that p38 SAPK is a potential pharmacological mediator for candidate drugs that target the endothelium.
Importance of Polymerization Initiator Systems and Interfacial Initiation of Polymerization in Adhesive Bonding of Resin to Dentin (1991)

Although various adhesive resins for dentin have been developed and used clinically, most attention has been directed to adhesion-promoting monomers and pre-treatment agents. The role of polymerization initiator systems in bonding has been overlooked. The purpose of this work was to study the role of initiators from the viewpoint of interfacial initiation of polymerization in dentin bonding. The bond strength between dentin and methyl methacrylate resin was significantly improved by a possible interfacial initiation with (1) the combination of ferric chloride, adsorbed onto dentin, and oxidized tri-n-butylborane (TBBO) and (2) the addition of tertiary butyl peroxymaleic acid (containing a carboxylic acid group, which has an affinity with dentin) to chemically- or light-activated initiator systems.

The use of transcriptional profiles to predict adult mosquito age under field conditions (2006)

Age is a critical determinant of an adult female mosquito's ability to transmit a range of human pathogens. Despite its central importance, relatively few methods exist with which to accurately determine chronological age of field-caught mosquitoes. This fact is a major constraint on our ability to fully understand the relative importance of vector longevity to disease transmission in different ecological contexts. It also limits our ability to evaluate novel disease control strategies that specifically target mosquito longevity. We report the development of a transcriptional profiling approach to determine age of adult female Aedes aegypti under field conditions. We demonstrate that this approach surpasses current cuticular hydrocarbon methods for both accuracy of predicted age as well as the upper limits at which age can be reliably predicted. The method is based on genes that display age-dependent expression in a range of dipteran insects and, as such, is likely to be broadly applicable to other disease vectors.
CPSeg: Cluster-free Panoptic Segmentation of 3D LiDAR Point Clouds (2021)

A fast and accurate panoptic segmentation system for LiDAR point clouds is crucial for autonomous driving vehicles to understand the surrounding objects and scenes. Existing approaches usually rely on proposals or clustering to segment foreground instances. As a result, they struggle to achieve real-time performance. In this paper, we propose a novel real-time end-to-end panoptic segmentation network for LiDAR point clouds, called CPSeg. In particular, CPSeg comprises a shared encoder, a dual-decoder, and a cluster-free instance segmentation head, which is able to dynamically pillarize foreground points according to the learned embedding. Then, it acquires instance labels by finding connected pillars with a pairwise embedding comparison. Thus, the conventional proposal-based or clustering-based instance segmentation is transformed into a binary segmentation problem on the pairwise embedding comparison matrix. To help the network regress instance embedding, a fast and deterministic depth completion algorithm is proposed to calculate the surface normal of each point cloud in real-time. The proposed method is benchmarked on two large-scale autonomous driving datasets: SemanticKITTI and nuScenes. Notably, extensive experimental results show that CPSeg achieves state-of-the-art results among real-time approaches on both datasets.
Estrogen and progestogen use in postmenopausal women (2008)

: Recent data support the initiation of HT around the time of menopause to treat menopause-related symptoms; to treat or reduce the risk of certain disorders, such as osteoporosis or fractures in select postmenopausal women; or both. The benefit-risk ratio for menopausal HT is favorable close to menopause but decreases with aging and with time since menopause in previously untreated women.

Circulating Tumor Cells (2012)

The analysis of circulating tumor cells (CTCs) as a real-time liquid biopsy approach can be used to obtain new insights into metastasis biology, and as companion diagnostics to improve the stratification of therapies and to obtain insights into the therapy-induced selection of cancer cells. In this book, we will cover all the different facets of CTCs to assemble a huge corpus of knowledge on cancer dissemination: technologies for their enrichment, detection, and characterization; their analysis at the single-cell level; their journey as CTC microemboli; their clinical relevance; their biology with the epithelial-to-mesenchymal transition (EMT); their stem-cell properties; their potential to initiate metastasis at distant sites; their ex vivo expansion; and their escape from the immune system.

Molecular Mechanisms Involved in the Pathogenesis of Alphavirus-Induced Arthritis (2013)

Arthritogenic alphaviruses, including Ross River virus (RRV), Chikungunya virus (CHIKV), Sindbis virus (SINV), Mayaro virus (MAYV), O'nyong-nyong virus (ONNV), and Barmah Forest virus (BFV), cause incapacitating and long lasting articular disease/myalgia. Outbreaks of viral arthritis and the global distribution of these diseases point to the emergence of arthritogenic alphaviruses as an important public health problem. This review discusses the molecular mechanisms involved in alphavirus-induced arthritis, exploring the recent data obtained with in vitro systems and in vivo studies using animal models and samples from patients. The factors associated to the extension and persistence of symptoms are highlighted, focusing on (a) virus replication in target cells, and tissues, including macrophages and muscle cells; (b) the inflammatory and immune responses with recruitment and activation of macrophage, NK cells and T lymphocytes to the lesion focus and the increase of inflammatory mediators levels; and (c) the persistence of virus or viral products in joint and muscle tissues. We also discuss the importance of the establishment of novel animal models to test new molecular targets and to develop more efficient and selective drugs to treat these diseases.

Spinal Cord Monitoring of Experimental Incomplete Cervical Spinal Cord Injury (1981)

Incomplete spinal cord injuries occur as a result of contusion and mechanical compression of neural tissue. Anterior spinal cord compression may physiologically prevent optimal recovery of spinal cord function for varying periods of time. The aim of this research was to study an animal model of incomplete cervical cord injury with a spinal cord monitoring system utilizing computer-averaged cortical evoked potentials. Two animal models were utilized: a contusion injury by the weight drop method and an anterior cord compression injury. Results indicate that incomplete cord injuries of both types will recover depending upon the amount of initial force or energy applied and the length of time compression is applied. Thirteen compression and 14 contusion injuries were studied. Cortical evoked potentials measured in seventeen dogs paralleled the degree of cord injury as well as recovery.
