The pump power dependence of the femtosecond relaxation of CdSe nanoparticles observed in the spectral range from visible to infrared (2002)

The pump power dependence of the relaxation dynamics of CdSe nanoparticles (NPs) was studied with femtosecond pump probe spectroscopy at observation wavelengths of the first exciton transition at 560 nm, the near infrared (NIR) absorption at 2 μm, and the transient mid-infrared (IR) absorption at 4.5 μm. Excitation with less than one photon per particle leads to bleaching of the excitonic transitions, and the bleach intensity is initially linear to the pump power. At higher pump power the bleach intensity levels off, when complete saturation of the excitonic transition is reached. At the same time, increasing pump power causes an acceleration of the bleach decay, which is due to additional Auger processes when multiple excitons are formed in the NPs. In addition, the pump power effect was investigated for the NIR and IR regions, at 2 and 4.5 μm wavelength, respectively. Whereas the IR transients are very similar to the ones observed for the bleach, the NIR transients behave completely different. No pump power dependence was found for the transients at 2 μm when pumped in a power range from 0.5 to 5 μJ per pulse. The results show that the fs transients in the visible (bleach) and IR (absorption) regions are due to electron relaxation in the conduction band and the NIR transients are due to the relaxation of the hole. Furthermore, it suggests that in the investigated CdSe NPs, Auger processes act much more efficiently on the electrons than for the holes.
Embedding objects during 3D printing to add new functionalities (2016)

A novel method for integrating and embedding objects to add new functionalities during 3D printing based on fused deposition modeling (FDM) (also known as fused filament fabrication or molten polymer deposition) is presented. Unlike typical 3D printing, FDM-based 3D printing could allow objects to be integrated and embedded during 3D printing and the FDM-based 3D printed devices do not typically require any post-processing and finishing. Thus, various fluidic devices with integrated glass cover slips or polystyrene films with and without an embedded porous membrane, and optical devices with embedded Corning(®) Fibrance™ Light-Diffusing Fiber were 3D printed to demonstrate the versatility of the FDM-based 3D printing and embedding method. Fluid perfusion flow experiments with a blue colored food dye solution were used to visually confirm fluid flow and/or fluid perfusion through the embedded porous membrane in the 3D printed fluidic devices. Similar to typical 3D printed devices, FDM-based 3D printed devices are translucent at best unless post-polishing is performed and optical transparency is highly desirable in any fluidic devices; integrated glass cover slips or polystyrene films would provide a perfect optical transparent window for observation and visualization. In addition, they also provide a compatible flat smooth surface for biological or biomolecular applications. The 3D printed fluidic devices with an embedded porous membrane are applicable to biological or chemical applications such as continuous perfusion cell culture or biocatalytic synthesis but without the need for any post-device assembly and finishing. The 3D printed devices with embedded Corning(®) Fibrance™ Light-Diffusing Fiber would have applications in display, illumination, or optical applications. Furthermore, the FDM-based 3D printing and embedding method could also be utilized to print casting molds with an integrated glass bottom for polydimethylsiloxane (PDMS) device replication. These 3D printed glass bottom casting molds would result in PDMS replicas with a flat smooth bottom surface for better bonding and adhesion.
Thermal Fatigue Cracking of an IM7/5250-4 Cross Ply Laminate: Experimental and Analytical Observations (2009)

Coupons of a balanced and symmetric cross ply laminate with polished edges made from IM7/5250-4 were thermally cycled between room and liquid nitrogen temperatures to induce cracks in the matrix. Edge crack densities for each symmetric lamina pair were recorded as a function of the number of cycles. Coupons with an epoxy coating on the polished edges experienced minimal cracking in all interior plies compared to significant cracking for uncoated specimens. This suggests that edge effects play a dominant role in crack initiation. Crack counts were quite different than recorded by another research group for nearly identical tests. Thermal shock was eliminated as a possible significant contributor to the overall physics driving crack formation. Stress analysis was used to support discussions that explain some of the observed trends in crack densities in the various ply pairs. The number of thermal cycles reached 2600 without a clear indication of crack saturation in any of the plies.
Magnetic properties, magnetic cluster size, and read-write performance of CoPtCr-SiO/sub 2/ perpendicular recording media (2003)

The characteristics of CoPtCr-SiO/sub 2/ perpendicular media were investigated, especially focusing on the dependence of magnetic properties and read-write performance on magnetic cluster size. H/sub c/ increases with reducing magnetic cluster size. As magnetic cluster size decreases, media noise and signal-to-noise ratio are improved and magnetic write width becomes narrower, indicating that reducing the magnetic cluster size is an effective means to increase both bit and track densities. However, diminution of magnetic cluster size degrades thermal stability. Lowering the magnetic cluster size threshold, above which a medium is thermally stable, is necessary in order to obtain a low noise and thermally stable medium.
Image Digestion and Relevance Feedback in the ImageRover WWW Search Engine (1997)

ImageRover is a search by image content navigation tool for the world wide web. The staggering size of the WWW dictates certain strategies and algorithms for image collection, digestion, indexing, and user interface. This paper describes two key components of the ImageRover strategy: image digestion and relevance feedback. Image digestion occurs during image collection; robots digest the images they find, computing image decompositions and indices, and storing this extracted information in vector form for searches based on image content. Relevance feedback occurs during index search; users can iteratively guide the search through the selection of relevant examples. ImageRover employs a novel relevance feedback algorithm to determine the weighted combination of image similarity metrics appropriate for a particular query. ImageRover is available and running on the web site. 1 Introduction For some time now, there have been &quot;spiders,&quot; &quot;worms,&quot; and other search engines crawling the World ...
The Current Role of Endourologic Management of Renal Transplantation Complications (2013)

Introduction. Complications following renal transplantation include ureteral obstruction, urinary leak and fistula, urinary retention, urolithiasis, and vesicoureteral reflux. These complications have traditionally been managed with open surgical correction, but minimally invasive techniques are being utilized frequently. Materials and Methods. A literature review was performed on the use of endourologic techniques for the management of urologic transplant complications. Results. Ureterovesical anastomotic stricture is the most common long-term urologic complication following renal transplantation. Direct vision endoureterotomy is successful in up to 79% of cases. Urinary leak is the most frequent renal transplant complication early in the postoperative period. Up to 62% of patients have been successfully treated with maximal decompression (nephrostomy tube, ureteral stent, and Foley catheter). Excellent outcomes have been reported following transurethral resection of the prostate shortly after transplantation for patients with urinary retention. Vesicoureteral reflux after renal transplant is common. Deflux injection has been shown to resolve reflux in up to 90% of patients with low-grade disease in the absence of high pressure voiding. Donor-gifted and de novo transplant calculi may be managed with shock wave, ureteroscopic, or percutaneous lithotripsy. Conclusions. Recent advances in equipment and technique have allowed many transplant patients with complications to be effectively managed endoscopically.
Blockchain in Insurance: Exploratory Analysis of Prospects and Threats (2021)

Ever since the first generation of blockchain technology became very successful and the FinTech enormously benefited from it with the advent of cryptocurrency, the second and third generations championed by Ethereum and Hyperledger have explored the extension of blockchain in other domains like IoT, supply chain management, healthcare, business, privacy, and data management. A field as huge as the insurance industry has been underrepresented in literature. Therefore, this paper presents how investments in blockchain technology can profit the insurance industry. We discuss the basics of blockchain technology, popular platforms in use today, and provide a simple theoretical explanation of the insurance sub-processes which blockchain can mutate positively. We also discuss hurdles to be crossed to fully implement blockchain solutions in the insurance domain.
Phorbol ester induces cultured endothelial cells to invade a fibrin matrix in the presence of fibrinolytic inhibitors (1987)

We have previously shown that the tumor promoter 4 beta-phorbol 12-myristate 13-acetate (PMA) induces capillary endothelial cells grown to confluency on the surface of three-dimensional collagen gels to invade the underlying matrix and to form capillary-like tubular structures, a phenomenon mimicking angiogenic processes that occur in vivo (Montesano and Orci: Cell, 42:469-477, 1985). Since angiogenesis frequently occurs within a fibrin-rich extracellular matrix, we have examined the ability of PMA-treated endothelial cells to invade fibrin gels. Control endothelial cells grown on fibrin gels formed a confluent monolayer on the gel surface and did not invade the underlying matrix. Treatment of the cultures with PMA resulted in a progressive lysis of the substrate without invasion of the fibrin matrix. However, if the cells were treated with PMA either in the presence of fibrinolytic inhibitors (Trasylol, epsilon-aminocaproic acid) or in the absence of detectable plasminogen, dissolution of the substrate was prevented, and the endothelial cells invaded the fibrin gel, forming vessel-like tubular structures similar to those previously observed with collagen gels. These results demonstrate that the invasive and morphogenetic events induced by PMA do not necessarily require an interaction between endothelial cells and collagen fibrils but can also occur with other biologically relevant substrata. They also suggest (1) that invasion may occur via a plasmin-independent mechanism and (2) that in vivo, neutralization of excess proteolytic activity may play an important permissive role in angiogenesis and other invasive processes by preventing uncontrolled matrix degradation.
Targeting Wolman Disease and Cholesteryl Ester Storage Disease: Disease Pathogenesis and Therapeutic Development (2017)

Wolman disease (WD) and cholesteryl ester storage disease (CESD) are lysosomal storage diseases (LSDs) caused by a deficiency in lysosomal acid lipase (LAL) due to mutations in the <i>LIPA</i> gene. This enzyme is critical to the proper degradation of cholesterol in the lysosome. LAL function is completely lost in WD while some residual activity remains in CESD. Both are rare diseases with an incidence rate of less than 1/100,000 births for WD and approximate 2.5/100,000 births for CESD. Clinical manifestation of WD includes hepatosplenomegaly, calcified adrenal glands, severe malabsorption and a failure to thrive. As in CESD, histological analysis of WD tissues reveals the accumulation of triglycerides (TGs) and esterified cholesterol (EC) in cellular lysosomes. However, the clinical presentation of CESD is less severe and more variable than WD. This review is to provide an overview of the disease pathophysiology and the current state of therapeutic development for both of WD and CESD. The review will also discuss the application of patient derived iPSCs for further drug discovery.
AppIntent (2013)

Android phones often carry personal information, attracting malicious developers to embed code in Android applications to steal sensitive data. With known techniques in the literature, one may easily determine if sensitive data is being transmitted out of an Android phone. However, transmission of sensitive data in itself does not necessarily indicate privacy leakage; a better indicator may be whether the transmission is by user intention or not. When transmission is not intended by the user, it is more likely a privacy leakage. The problem is how to determine if transmission is user intended. As a first solution in this space, we present a new analysis framework called AppIntent. For each data transmission, AppIntent can efficiently provide a sequence of GUI manipulations corresponding to the sequence of events that lead to the data transmission, thus helping an analyst to determine if the data transmission is user intended or not. The basic idea is to use symbolic execution to generate the aforementioned event sequence, but straightforward symbolic execution proves to be too time-consuming to be practical. A major innovation in AppIntent is to leverage the unique Android execution model to reduce the search space without sacrificing code coverage. We also present an evaluation of AppIntent with a set of 750 malicious apps, as well as 1,000 top free apps from Google Play. The results show that AppIntent can effectively help separate the apps that truly leak user privacy from those that do not.
Social Networks and Physical Activity Behaviors Among Cancer Survivors: Data From the 2005 Health Information National Trends Survey (2015)

The study examined the relation between social networks and physical activity behaviors among cancer survivors. The authors examined 873 cancer survivors (596 women, 277 men) 50 years of age or older who participated in the 2005 Health Information National Trends Survey. Multivariate logistic regression analysis showed that survivors who talked about health with friends/family were more likely to pay attention to new physical activity recommendations (OR = 2.89, CI [1.01, 8.33]). Female survivors were more likely to pay attention to new physical activity recommendations (OR = 2.65, CI [1.55, 4.53]) and more likely to have seen, heard, or read physical activity/exercise and cancer information within the past 12 months (OR = 2.09, CI [1.13, 3.85]) compared with their male counterparts. For male survivors, those who were a member of at least one community organization were more likely to pay attention to new physical activity/exercise recommendations (OR = 5.31, CI [1.32, 21.22]) than the men who were not members. Overall, cancer survivors with a social network (i.e., talking to family/friends about health) were more likely to pay attention to new exercise recommendations compared with those who did not have a social network. Significant differences were also observed by gender with physical activity levels, knowledge, and attitudes. Social networking is an important component in cancer survivorship and further research is needed to encourage social networking strategies that might facilitate in increasing physical activity behaviors among cancer survivors.
Detection sensitivity and power consumption vs. operation modes using system-on-chip based Doppler radar occupancy sensor (2012)

A low cost, low power Doppler radar occupancy sensor is developed by building a customized passive sensor node into a low power System-on-Chip (SoC) CC2530 RF transceiver. Experiment on the periodic moving mechanic target illustrates that this SoC based Doppler radar sensor is able to accurately detect the motion of the target under CW, modulated CW and packet operation modes. The study on sensitivity and power consumption under these modes indicates the most cost efficiency and power efficiency can be achieved by operating the sensor under packet mode with an optimum output power level.
Structure of potato inhibitor complex of carboxypeptidase A at 5.5-A resolution. (1980)

The complex of the 39-amino inhibitor (potato) of bovine carboxypeptidase A (carboxypeptidase; peptidyl-L-amino-acid hydrolase, EC 3.4.12.2) was crystallized in space group P32. There are two protein-inhibitor complexes in the asymmetric unit. These crystals exhibited pseudo-P3221 symmetry due to twinning about the a3 axis. Heavy atom difference Patterson maps and rotation functions indicated, however, that the noncrystallographic twofold axis that relates these two complexes is nearly coincident with the a3 axis. Consequently, to a good approximation at low resolution, the space group of the complex is P3221 and the effects of twinning may be ignored. The structure was solved by using multiple isomorphous replacement and molecular replacement techniques. At 5.5-A resolution, the multiple isomorphous replacement map was readily interpretable in terms of the known native carboxypeptidase A structure plus extra density around the active site. The position of this extra density is consistent with the binding mode for extended substrate proposed from earlier model building studies with the native enzyme (Lipscomb, W.N., Hartsuck, J.A., Reeke, G.N., Quiocho, F.A. Bethge, P.H., Ludwig, M.L., Steitz, T.A., Muirhead, H. & Coppola, J.C. (1968) Brookhaven Symp. Biol. 21, 24-90).
España ante el nuevo reparto de poder institucional en la UE (2019)

Teniendo en cuenta los resultados de las recientes elecciones al Parlamento Europeo, los jefes de Estado y de Gobierno de la UE han iniciado un complejo proceso de negociacion que llevara a un nuevo reparto de poder en las principales instituciones de la Union. Tras los primeros movimientos, y garantizada la existencia de una mayoria europeista tanto en el Parlamento como en el Consejo Europeo (y, por tanto, en la Comision), se han vislumbrado dos bloques principales conformados en torno a lineas ideologicas: uno formado por buena parte de los partidos socialistas y liberales y encabezado por los gobiernos de Francia, Espana, los Paises Bajos, Belgica y Portugal, y otro que gira en torno al Partido Popular Europeo (PPE) y el Gobierno aleman de la canciller Merkel. Cabe, sin embargo, resaltar la porosidad de dichos bloques, al entremezclarse las logicas politico-ideologica y la del interes nacional. En este sentido destaca, por ejemplo, la tendencia de los Paises Bajos a alinearse con Alemania en temas europeos, asi como la de Francia a reconocer el poder aleman y construir coaliciones alternativas con el objetivo de reforzar su posicion negociadora bilateral con Alemania. 
Ante el incipiente reparto de poder institucional en la UE, este analisis ofrece algunas consideraciones que podrian ayudar a orientar la estrategia de negociacion para el gobierno de Espana. En concreto, se hace hincapie en dos principios: (1) la necesidad de encontrar un equilibrio entre Alemania (cuya relacion se presenta indispensable para garantizar el avance de los objetivos estrategicos de Espana en la UE en los proximos cinco anos), Francia y la condicion del presidente del Gobierno, Pedro Sanchez, de lider de la familia socialdemocrata en el Consejo Europeo y el Parlamento Europeo; y (2) la necesidad de que la iniciativa de acercamiento entre los dos principales bloques ideologicos venga de Espana, ya que de no ser asi nuestro pais podria quedar rezagado en el futuro reparto de poder.
CI‐Graph simultaneous localization and mapping for three‐dimensional reconstruction of large and complex environments using a multicamera system (2010)

Abstract Submapping and graphical methods have been shown to be valuable approaches to simultaneous localization and mapping (SLAM), providing significant advantages over the classical extended Kalman filter (EKF) solution: they are faster and, when using local coordinates , produce more consistent estimates. The main contribution of this paper is CI‐Graph SLAM , a novel algorithm that is able to efficiently map large environments by building a graph of submaps and a spanning tree of this graph with the following properties: (1) any pair of neighboring submaps in the spanning tree are conditionally independent and (2) the current submap is always up to date, containing the marginal probabilities of the submap variables given all previous measurements. Thanks to these properties, an old submap can be updated at any time by performing a single propagation from the current map to the old submap along the spanning tree. This operation is required only when a map is revisited, with a cost linear with the number of maps in the loop. At the end of the experiment the method performs a single propagation through the whole tree, recovering exactly the same marginals for all the map variables as the EKF–SLAM algorithm does, without ever needing to compute the whole covariance matrix. To evaluate CI‐Graph performance in extremely loopy environments, the method was tested using a synthetic Manhattan world. The behavior of the algorithm in large real environments is shown using the public data sets from the RAWSEEDS project in which a robot equipped with a trinocular camera traversed indoor and outdoor environments with several loops and revisited areas. Loops are robustly closed using a novel technique that detects candidate loop closures using a visual vocabulary tree and filters them using temporal and geometric constraints. Our experiments show that when using frontal cameras, the technique outperforms FAB‐MAP. The epipolar geometry of the loop‐closing images is used to find feature matches that are imposed on the CI‐Graph to correct the submap estimations along the loop. © 2010 Wiley Periodicals, Inc.
