A performance evaluation of MPEG-21 BSDL in the context of H.264/AVC (2004)

H.264/AVC is a new specification for digital video coding that aims at a deployment in a lot of multimedia applications, such as video conferencing, digital television broadcasting, and internet streaming. This is for instance reflected by the design goals of the standard, which are about the provision of an efficient compression scheme and a network-friendly representation of the compressed data. Those requirements have resulted in a very flexible syntax and architecture that is fundamentally different from previous standards for video compression. In this paper, a detailed discussion will be provided on how to apply an extended version of the MPEG-21 Bitstream Syntax Description Language (MPEG-21 BSDL) to the Annex B syntax of the H.264/AVC specification. This XML based language will facilitate the high-level manipulation of an H.264/AVC bitstream in order to take into account the constraints and requirements of a particular usage environment. Our performance measurements and optimizations show that it is possible to make use of MPEG-21 BSDL in the context of the current H.264/AVC standard with a feasible computational complexity when exploiting temporal scalability.
How to Prepare the Brightest Luminescent Coatings? (2013)

We address here the question of studying the parameters affecting the brightness of luminescent nanoparticulate coatings, among which are the absorption rate, the internal quantum yield of the phosphor nanoparticles, and the extraction factor of the emitted light in a solid angle perpendicular to the substrate. Experimental investigations are achieved on spray-deposited YVO4:Eu particles, a system whose synthesis and properties are well documented so that particles of different sizes and microstructure can be considered. This allows a quantitative evaluation of the factors affecting film brightness. Considering a film made from raw colloidal particles, this work shows that its brightness is limited by a factor of 5 due to altered quantum yield of nanoparticles, a factor of 1.75 by dielectric effects and a factor of 2.4 by light extraction issues. This investigation, through providing quantitative evaluations of these different parameters, opens the way toward a possible rational design of inorganic luminescent coatings, with a possible improvement of brightness that could reach a factor of 30 as compared to simple films made directly from colloidal suspensions.
Extracellular fluid redistribution during hemodialysis: bioimpedance measurement and model (2008)

Intradialytic fluid redistribution may cause hypotension. We hypothesized that measuring extracellular fluid volumes (ECV) with segmental bioimpedance analysis (SBIA) could test a simple, volume-driven model of redistribution among the arm, leg and trunk compartments. Patients (22, 5 females/17 males, with ages 60.2 +/- 9 years, weights 80.7 +/- 15 kg, heights 174 +/- 9 cm) were studied during 30 HD treatments on different days. Hypotensive symptoms (Hypo+) were observed in eight patients. ECVs in the arm, trunk and leg, respectively V(A), V(T) and V(L), were measured at initiation of, and throughout, dialysis. Two variables lambda(A) and lambda(L) were defined as V(A)/V(T) and V(L)/V(T). System dynamics, assuming initial equilibrium, are then described by two rate coefficients k(RL) and k(RA) and two constants beta and gamma. These were obtained using a Marquardt-Levenberg least-squares algorithm. Significant differences (Hypo+ versus Hypo-) for lambda(L) (0.55 +/- 0.13 versus 0.84 +/- 0.3, *p < 0.05) and lambda(A) (0.17 +/- 0.032 versus 0.23 +/- 0.07, **p < 0.01) were found. The small value of lambda(L) might indicate that less leg volume predisposes to hypotension, larger peripheral volume mitigates hypotension. Observed transport ratios indicated that the ratio of limb to trunk volume stabilized during dialysis after an initial adjustment. These data imply encumbered movement of water from the interstitial components around skeletal muscle in the arm and leg to those of the trunk and are useful in predicting anatomical or situational predispositions to hypotension.
Negative Regulation of CD45 Protein Tyrosine Phosphatase Activity by Ionomycin in T Cells (1991)

CD45 is a leukocyte-specific, transmembrane protein tyrosine phosphatase (PTPase) required for T cell responsiveness. How the activity of PTPases is regulated in vivo is unclear. Treatment of murine thymocytes and a variety of murine T cell lines with the calcium ionophore ionomycin decreased CD45 PTPase activity. Ionomycin treatment also led to a decreased phosphorylation of serine residues in CD45. These results indicate that increased intracellular calcium modulates CD45 PTPase activity, demonstrating regulation of CD45 PTPase activity in vivo, and also implicate serine dephosphorylation as a possible mechanism.

An Electrochemically Transduced XOR Logic Gate at the Molecular Level (2010)

Golden logic: The integration of both cathodic and anodic electrochemical current rectifiers (ECR) on a gold electrode (see picture) results in a molecular-level XOR logic gate with a high switch ratio between electrical output signals “1” and “0”. When the electrode is modified by the redox mediator ferrocene, successive XOR logic-gate functions can be carried out without resetting the system.
Correction: In-situ Effects of Eutrophication and Overfishing on Physiology and Bacterial Diversity of the Red Sea Coral Acropora hemprichii (2013)

Coral reefs of the Central Red Sea display a high degree of endemism, and are increasingly threatened by anthropogenic effects due to intense local coastal development measures. Overfishing and eutrophication are among the most significant local pressures on these reefs, but there is no information available about their potential effects on the associated microbial community. Therefore, we compared holobiont physiology and 16S-based bacterial communities of tissue and mucus of the hard coral Acropora hemprichii after 1 and 16 weeks of in-situ inorganic nutrient enrichment (via fertilizer diffusion) and/or herbivore exclusion (via caging) in an offshore reef of the Central Red Sea. Simulated eutrophication and/or overfishing treatments did not affect coral physiology with respect to coral respiration rates, chlorophyll a content, zooxanthellae abundance, or d 15 N isotopic signatures. The bacterial community of A. hemprichii was rich and uneven, and diversity increased over time in all treatments. While distinct bacterial species were identified as a consequence of eutrophication, overfishing, or both, two bacterial species that could be classified to the genus Endozoicomonas were consistently abundant and constituted two thirds of bacteria in the coral. Several nitrogen-fixing and denitrifying bacteria were found in the coral specimens that were exposed to experimentally increased nutrients. However, no particular bacterial species was consistently associated with the coral under a given treatment and the single effects of manipulated eutrophication and overfishing could not predict the combined effect. Our data underlines the importance of conducting field studies in a holobiont framework, taking both, physiological and molecular measures into account.
Fast link-disjoint path algorithm on parallel reconfigurable processor DAPDNA-2 (2008)

This paper proposes fast parallel link-disjoint path algorithm using dynamically reconfigurable processor and implements it on DAPDNA-2 (IPFlex Inc) which is newly structured. The conventional k-shortest path algorithm finds multiple link-disjoint paths between the source node and the destination node. When the network scale is large, the calculation time of k-shortest path algorithm increases rapidly. Moreover, in the worst case, k-shortest path algorithm can not find optimum link-disjoint path pair because this algorithm always finds the shortest path at first and removes those links from network. Our proposed algorithm collects all path information in the network and calculates optimum link-disjoint path pair (i.e. minimum cost link-disjoint path pair) at high speed by using parallel operation. Additionally, our proposed algorithm finds optimum link-disjoint path pair at a high rate in a limited of calculation time. The evaluation shows our proposed algorithm can decrease the calculation clock about 90%.
Thioxanthone derivatives as photoinitiators in micelle photopolymerization (1987)

Abstract This paper provides a complete survey of the primary processes involved in typical oil‐and water‐soluble thioxanthane derivatives dissolved in sodium dodecyl sulfate micelles, in the presence of monomers and amines. Special emphasis is laid on the determination of the rate constants of the different processes and the absorption spectra of the transients. Relevant data are shown and discussed with reference to the effectiveness of these molecules as photopolymerization initiators.
Electrically small RF coil arrays for medical &amp; wireless power applications (2013)

This paper analyzes the effect of close proximity for coil arrays and measures the S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</sub> mutual coupling, resonant frequency, and quality factor (Q) of arrays with 2, 4, & 8 coils. It is demonstrated that for vertically separated coils, the mutual coupling effect decays asymptotically as a function of separation distance; whereas for horizontally separated coils, there are two mutual coupling minima with one minima occurring for overlapping coils and the second minima similar to the vertically separated coils. Results from this study can be used to optimize electrically small RF coil arrays used in low-field MRI, NFC, and wireless power transfer.

Segmentation of Noisy Signals Generated By a Nanopore (2015)

ABSTRACT Nanopore-based single-molecule sequencing techniques exploit ionic current steps produced as biomolecules pass through a pore to reconstruct properties of the sequence. A key task in analyzing complex nanopore data is discovering the boundaries between these steps, which has traditionally been done in research labs by hand. We present an automated method of analyzing nanopore data, by detecting regions of ionic current corresponding to the translocation of a biomolecule, and then segmenting the region. The segmenter uses a divide-and-conquer method to recursively discover boundary points, with an implementation that works several times faster than real time and that can handle low-pass filtered signals.
Purging of peripheral blood stem cell grafts (1995)

The shortage of HLA-matched sibling donors for bone marrow transplant patients has stimulated interest in the use of alternative donors. As a result, there has been a dramatic increase in the use of autologous marrow transplantation, which avoids the complications of graft-versus-host disease, but may deprive the patient of a potentially beneficial graft-versus-disease response and runs the risk of returning occult tumor cells with the graft. There is increasing evidence that these cells may be associated with disease relapse post-transplant, and many methods have been developed for their removal ex vivo. Combinations of negative and positive selection may achieve elimination of tumor cells to the limits of detection of the most sensitive assays currently available. The marked trend toward the use of autologous grafts derived from blood rather than marrow has raised the question as to whether peripheral blood stem cell (PBSC) preparations should be purged of tumor. Data indicate that these grafts generally contain a lower tumor burden, although the stem cell mobilization procedure may recruit tumor cells into the peripheral circulation. Enrichment of CD34+ cells from apheresis products appears, at present, to be less efficient than from marrow and provides at best about a 2-3 log depletion of tumor. This has prompted proposals to follow positive selection by a small-scale purging procedure. Technical issues, such as preprocessing and pooling of collections prior to purging, remain to be addressed. Ultimately, the development of successful purging procedures for PBSC grafts will simply reemphasize the necessity of improving the efficacy of high-dose therapy.

The Constitution of Thalicarpine. (1967)

Reinvestigation on the constitution of thalicarpine, previously, isolated from Thalictrum and Hernandia species, was descrived. Ullmann condensation product of L-6'-bromolaudanosine and N-methyllaurotetanine was identified with natural thalicarpine. Accordingly, the revised constitution of thalicarpine was established to have the formula IX.
Preserving privacy in gps traces via uncertainty-aware path cloaking (2007)

Motivated by a probe-vehicle based automotive traffic monitoring system, this paper considers the problem of guaranteed anonymity in a dataset of location traces while maintaining high data accuracy. We find through analysis of a set of GPS traces from 233 vehicles that known privacy algorithms cannot meet accuracy requirements or fail to provide privacy guarantees for drivers in low-density areas. To overcome these challenges, we develop a novel time-to-confusion criterion to characterize privacy in a location dataset and propose an uncertainty-aware path cloaking algorithm that hides location samples in a dataset to provide a time-to-confusion guarantee for all vehicles. We show that this approach effectively guarantees worst case tracking bounds, while achieving significant data accuracy improvements.
Targeted MicroRNA Interference Promotes Postnatal Cardiac Cell Cycle Re-Entry (2013)

Mammalian heart cells undergo a marked reduction in proliferative activity shortly after birth, and thereafter grow predominantly by hypertrophy. Our understanding of the molecular mechanisms underlying cardiac maturation and senescence is based largely on studies at the whole-heart level. Here, we investigate the molecular basis of the acquired quiescence of purified neonatal and adult cardiomyocytes, and use microRNA interference as a novel strategy to promote cardiomyocyte cell cycle re-entry. Expression of cyclins and cyclin-dependent kinases (CDKs) and positive modulators were down-regulated, while CDK inhibitors and negative cell cycle modulators were up-regulated during postnatal maturation of cardiomyocytes. The expression pattern of microRNAs also changed dramatically, including increases in miR-29a, miR-30a and miR-141. Treatment of neonatal cardiomyocytes with miRNA inhibitors anti-miR-29a, anti-miR-30a, and antimiR-141 resulted in more cycling cells and enhanced expression of Cyclin A2 (CCNA2). Thus, targeted microRNA interference can reactivate postnatal cardiomyocyte proliferation.

Counting Cytokinesis Proteins Globally and Locally in Fission Yeast (2005)

We used fluorescence microscopy to measure global and local concentrations of 28 cytoskeletal and signaling proteins fused to yellow fluorescent protein (YFP) in the fission yeast Schizosaccharomyces pombe. Native promoters controlled the expression of these functional YFP fusion proteins. Fluorescence measured by microscopy or flow cytometry was directly proportional to protein concentration measured by quantitative immunoblotting. Global cytoplasmic concentrations ranged from 0.04 (formin Cdc12p) to 63 micromolar (actin). Proteins concentrated up to 100 times in contractile rings and 7500 times in spindle pole bodies at certain times in the cell cycle. This approach can be used to measure the global and local concentrations of any fusion protein.
Coaxial waveguide MRI (2011)

As ultrahigh-field MR imaging systems suffer from the standing wave problems of conventional coil designs, the use of antenna systems that generate travelling waves was suggested. As a modification to the original approach, we propose the use of a coaxial waveguide configuration with interrupted inner conductor. This concept can focus the radiofrequency energy to the desired imaging region in the human body and can operate at different Larmor frequencies without hardware modifications, as it is not limited by a lower cut-off frequency. We assessed the potential of the method with a hardware prototype setup that was loaded with a tissue equivalent phantom and operated with imaging areas of different size. Signal and flip angle distributions within the phantom were analyzed, and imaging at different Larmor frequencies was performed. Results were compared to a finite difference time domain simulation of the setup that additionally provides information on the spatial distribution of the specific absorption rate load. Furthermore, simulation results with a human model (virtual family) are presented. It was found that the proposed method can be used for MRI at multiple frequencies, achieving transmission efficiencies similar to other travelling wave approaches but still suffers from several limitations due to the used mode of wave propagation.
Intravenous nicardipine: cardiovascular effects and clinical relevance. (1988)

Nicardipine hydrochloride is the first intravenous dihydropyridine calcium antagonist to become available in the United States. Its chemical structure makes it unique among its drug class and confers clinically useful properties for the treatment of acute cardiovascular conditions, such as ischemia, hypertension, congestive heart failure, cerebrovascular disease, and related disorders. For patients with coronary artery disease, IV nicardipine reduces myocardial oxygen demand by reducing afterload and increases myocardial oxygen supply through coronary vasodilatation. Preliminary data suggest that nicardipine also has cardioprotective and vascular antispastic effects. Nicardipine has been shown to be effective in the treatment of mild to moderate hypertension both as monotherapy and in combination with other antihypertensive agents. In congestive heart failure, nicardipine enhances left ventricular pumping activity and augments coronary blood flow beyond that required by increased myocardial oxygen consumption. Its lack of major effects on sinoatrial and atrioventricular conduction makes it safe for use in patients with certain types of conduction disturbances. Nicardipine's rapid onset and short duration of action are additional advantages for use in the management of acute cardiovascular disorders.
