Promotion of content availability by playlist viewers in CDN-P2P systems (2013)

This paper assesses the effectiveness of playlists for improving the content availability in CDN-P2P networks that distributes YouTube-like videos. Real data collected from YouTube was used and the popularity patterns of playlists and first page videos were characterized. Moreover, the impact of playlist viewers on content availability was evaluated. Results show that the improvement in content availability is about 40% for highly connected playlist viewers. For systems with less connected playlist viewers, the improvement exceeds 20% for different scenarios.
Composite polymer hydrogels as draw agents in forward osmosis and solar dewatering (2011)

We report here on new composite polymer hydrogel particles with light-absorbing carbon particles incorporated within them that can be used as draw agents in the forward osmosis process of desalination. These hydrogels are synthesized by free-radical polymerization of different monomers (e.g. sodium acrylate, N-isopropylacrylamide or their mixtures) and the crosslinker N,N′-methylenebisacrylamide with light-absorbing carbon particles. We have previously shown that hydrogel particles are able to draw pure water through forward osmosis membranes, and then the water can be removed by pressure or heating, or a mixture of both. The incorporation of light-absorbing particles leads to natural, enhanced heating and dewatering of the composites compared to neat hydrogels during such irradiation with light. However, it is also advantageously found that these composite polymer hydrogels exhibit higher swelling ratios, and thus produce higher water fluxes in the FO process. Furthermore, with the increasing loadings of carbon particles, the water recovery rates from the swollen composite hydrogels are found to be greatly enhanced.

On Optimal Scheduling in Duty-Cycled Industrial IoT Applications Using IEEE802.15.4e TSCH (2013)

As exposed in a recent report by General Electric, an industrial Internet of Things (IoT) is emerging as a commercially viable embodiment of the IoT where physical sensors gather data readings from the field and deliver the traffic to the Internet. The collected real-time big data, in turn, allow the optimizing of entire industry verticals with enormous return of investments. Although opportunities are ample, it comes along with serious engineering design challenges as industrial applications have stringent requirements on delay, lifetime and standards-compliance. To this end, we advocate the use of an IEEE/IETF standardized IoT architecture along with a recently introduced data-centric scheduling algorithm known as traffic aware scheduling algorithm (TASA). Applying graph theoretical tools to the multi-channel, time-synchronized, and duty-cycled nature of TASA, we rigorously derive optimality and bounds on the minimum number of needed active slots (impacting end-to-end delays) and the network duty-cycle (impacting lifetime). We demonstrate the enormous superiority of TASA over traditional IEEE802.15.4/ZigBee approaches in terms of energy efficiency. The outcome of this paper is currently to lay foundations of the recently formed IETF standardization group 6TSCH with the aim to significantly improve IoT data flows over IEEE802.15.4e TSCH and IETF 6LoWPAN/ROLL enabled technologies.
TV anytime as an application scenario for MPEG-7 (2000)

The ISO/MPEG group has identified a wide range of application scenarios [1] for their emerging MPEG-7 standard on audio-visual metadata. TV Anytime with their vision of future digital TV services [2] encompasses a large number of them. As TV Anytime has also identified metadata as one of the key requirements to realize their vision, MPEG-7 is the natural candidate to fill that role. Here, we describe technically how metadata for the TV Anytime scenario can be created using MPEG-7.
B cell activation via CD40 is required for specific antibody production by antigen-stimulated human B cells. (1993)

Costimulatory signals provided by T cells are required for B cells to produce specific antibody (Ab) to T-dependent antigen (Ag) bacteriophage phi x 174. In this study, we demonstrate that if cultured in the presence of anti-CD40, interleukin 10 (IL-10), and Ag, purified B cells can produce antiphage Ab in quantities comparable to those synthesized by B cells cocultured with Ag and T cells. Isotypes produced by B cells in this culture system correspond to those observed in sera of B cell donors. Culture of immunoglobulin (Ig)D- and IgD+ B cells reveals that Ag-induced production of antiphage Ab is restricted to IgD- subset of B cells. In the absence of Ag, anti-CD40/IL-10-stimulated B cells produce only minute amounts of antiphage Ab, indicating that Ag stimulation is indispensable and provides a signal that is synergistic with anti-CD40 and IL-10. Addition of a soluble form of the CD40 ligand (sgp39) to the culture system has a similar effect on specific Ab synthesis as anti-CD40; addition of the soluble construct, CD40 Ig, known to inhibit gp39/CD40 interaction, suppresses in vitro antiphage Ab production by Ag exposed peripheral blood mononuclear cells. Finally, in vivo requirement of gp39/CD40 interaction for specific Ab production was demonstrated by the finding that activated T cells from patients with x-linked hyper IgM syndrome express functionally defective gp39 and respond with depressed Ab titers and fail to switch from IgM to IgG after multiple phage immunizations. These observations illustrate that in vitro and possibly in vivo Ag-specific Ab synthesis requires the presence of Ag and IL-10, and activation signals via CD40.
Extracellular Matrix Degradation by Cultured Mesangial Cells: Mediators and Modulators (2003)

Decreased degradation of the glomerular extracellular matrix (ECM) is thought to contribute to the accumulation of glomerular ECM that occurs in diabetic nephropathy and other chronic renal diseases. Several lines of evidence indicate a key role for the plasminogen activator/plasminogen/plasmin system in glomerular ECM degradation. However, which of the two plasminogen activators (PAs) present in renal tissue, tissue plasminogen activator (tPA) or urokinase-type plasminogen activator (uPA), is responsible for plasmin generation and those factors that modulate the activity of this system remain unclear. This study utilized mesangial cells isolated from mice with gene deletions for tPA, uPA, and plasminogen activator inhibitor 1 (PAI-1) to further delineate the role of the PA/plasminogen/plasmin system in ECM accumulation. ECM degradation by uPA-null mesangial cells was not significantly different from controls (92% +/- 1%, n = 12). In contrast, ECM degradation by tPA-null mesangial cells was markedly reduced (-78 +/- 1%, n = 12, P < 0.05) compared with controls, whereas tPA/uPA double-null mesangial cells degraded virtually no ECM. Previous studies from this laboratory have established that transforming growth factor-beta1 (TGFbeta1) inhibits ECM degradation by cultured mesangial cells by increasing the production of PAI-1, the major physiological PA inhibitor. In keeping with this observation, TGFbeta1 (1 ng/ml) had no effect on ECM degradation by PAI-1-null MC. High glucose levels (30 mM) in the presence or absence of insulin (0.1 mM) caused a moderate increase in ECM degradation by normal human mesangial cells. In contrast, glycated albumin, whose concentration is known to increase in diabetes, produced a dose-dependent (0.2-0.5 mg/ml) inhibition of ECM degradation by normal human mesangial cells. Taken together, these results document the importance of tPA versus uPA in renal plasmin production and indicate that in contrast to elevated glucose, glycated albumin may contribute to ECM accumulation in diabetic nephropathy.
Fully elastic interconnects on nanopatterned elastomeric substrates (2006)

Elastically stretchable metal interconnects are required for electronic skin. To date, the resistance of such thin-film interconnects has been found to increase much more with mechanical strain than expected from purely geometrical deformation of the conductor. It has been discovered that the resistance change due to fully elastic deformation is minimal when the metal films are deposited on pyramidal nanopatterned surfaces. The nanopattern constrains the film to purely elastic deformation by localizing the microcracks that are formed in the conductor during stretching. Between 0% and 25% mechanical strain, the electrical resistance increases by only 60%, which is in close agreement with purely geometric deformation.
Risk assessment in distributed authorization (2005)

Distributed authorization takes into account several elements, including certificates that may be provided by non-local actors. While most trust management systems treat all assertions as equally valid up to certificate authentication, realistic considerations may associate risk with some of these elements; some actors may be less trusted than others, some elements may be more computationally expensive to obtain, and so forth. Furthermore, practical online authorization may require certain levels of risk to be tolerated. In this paper, we introduce a trust management logic that incorporates formal risk assessment. This formalization allows risk levels to be associated with authorization elements, and promotes development of a distributed authorization algorithm allowing tolerable levels of risk to be precisely specified and rigorously enforced.
Investigations on a series of novel ionic liquids containing the [closo-B12Cl12]2− dianion (2012)

A series of novel imidazolium, ammonium, phosphonium and pyridinium based salts with the [closo-B12Cl12]2− dianion were synthesized by straight forward metathetic reactions and characterized by physical methods. The melting point of each salt with [closo-B12Cl12]2− dianion was measured to investigate if it can be classified in the field of ionic liquids. Thermodynamic results showed observed higher melting points, which can be illustrated both from the higher symmetry of the dianion and the enhanced electrostatic forces of the salts synthesized. Given the above mentioned reasons, the [closo-B12Cl12]2− dianion containing ionic liquids can be designed either by optimizing the structure of cation, especially of the alkylation pattern which naturally affected the cations' packing efficiency, or by shielding the cation–dianion interactions with appropriate hydrogen bond (H-bond) donors to form ‘quasi-eutectic ILs’. This can be rationalized by the increased interionic separation and the consequent weakening of the electrostatic forces. Additionally, influence of H-bond interactions on the phase transition temperatures of [closo-B12Cl12]2− dianion containing salts was also investigated and related changes were explained by ab initio calculations, illustrating weak H-bond interactions between the hydroxy protons and the chlorine atoms which showed modest effects on the melting points of the salts with [closo-B12Cl12]2− dianion.
ABF++: fast and robust angle based flattening (2005)

Conformal parameterization of mesh models has numerous applications in geometry processing. Conformality is desirable for remeshing, surface reconstruction, and many other mesh processing applications. Subject to the conformality requirement, these applications typically benefit from parameterizations with smaller stretch. The Angle Based Flattening (ABF) method, presented a few years ago, generates provably valid conformal parameterizations with low stretch. However, it is quite time-consuming and becomes error prone for large meshes due to numerical error accumulation. This work presents ABF&amp;plus;&amp;plus;, a highly efficient extension of the ABF method, that overcomes these drawbacks while maintaining all the advantages of ABF. ABF++ robustly parameterizes meshes of hundreds of thousands and millions of triangles within minutes. It is based on three main components: (1) a new numerical solution technique that dramatically reduces the dimension of the linear systems solved at each iteration, speeding up the solution; (2) a new robust scheme for reconstructing the 2D coordinates from the angle space solution that avoids the numerical instabilities which hindered the ABF reconstruction scheme; and (3) an efficient hierarchical solution technique. The speedup with (1) does not come at the expense of greater distortion. The hierarchical technique (3) enables parameterization of models with millions of faces in seconds at the expense of a minor increase in parametric distortion. The parameterization computed by ABF++ are provably valid, that is they contain no flipped triangles. As a result of these extensions, the ABF++ method is extremely suitable for robustly and efficiently parameterizing models for geometry-processing applications.
Ectodomain shedding of L1 adhesion molecule promotes cell migration by autocrine binding to integrins (2001)

The L1 adhesion molecule plays an important role in axon guidance and cell migration in the nervous system. L1 is also expressed by many human carcinomas. In addition to cell surface expression, the L1 ectodomain can be released by a metalloproteinase, but the biological function of this process is unknown. Here we demonstrate that membrane-proximal cleavage of L1 can be detected in tumors and in the developing mouse brain. The shedding of L1 involved a disintegrin and metalloproteinase (ADAM)10, as transfection with dominant-negative ADAM10 completely abolishes L1 release. L1-transfected CHO cells (L1-CHO) showed enhanced haptotactic migration on fibronectin and laminin, which was blocked by antibodies to alpha v beta 5 and L1. Migration of L1-CHO cells, but not the basal migration of CHO cells, was blocked by a metalloproteinase inhibitor, indicating a role for L1 shedding in the migration process. CHO and metalloproteinase-inhibited L1-CHO cells were stimulated to migrate by soluble L1-Fc protein. The induction of migration was blocked by alpha v beta 5-specific antibodies and required Arg-Gly-Asp sites in L1. A 150-kD L1 fragment released by plasmin could also stimulate CHO cell migration. We propose that ectodomain-released L1 promotes migration by autocrine/paracrine stimulation via alpha v beta 5. This regulatory loop could be relevant for migratory processes under physiological and pathophysiological conditions.
Vaccine Protection against Simian Immunodeficiency Virus by Recombinant Strains of Herpes Simplex Virus (2000)

An effective vaccine for AIDS may require development of novel vectors capable of eliciting long-lasting immune responses. Here we report the development and use of replication-competent and replication-defective strains of recombinant herpes simplex virus (HSV) that express envelope and Nef antigens of simian immunodeficiency virus (SIV). The HSV recombinants induced antienvelope antibody responses that persisted at relatively stable levels for months after the last administration. Two of seven rhesus monkeys vaccinated with recombinant HSV were solidly protected, and another showed a sustained reduction in viral load following rectal challenge with pathogenic SIVmac239 at 22 weeks following the last vaccine administration. HSV vectors thus show great promise for being able to elicit persistent immune responses and to provide durable protection against AIDS.

Variation of the hepatitis C virus 5' non-coding region: implications for secondary structure, virus detection and typing (1995)

Variation in the 5' non-coding region (5'NCR) of hepatitis C virus (HCV) was investigated in detail by comparing 314 5'NCR sequences of viruses of genotypes 1 to 6. Evidence was obtained for the existence of associations between particular 5'NCR sequence motifs and virus types and subtypes. No recombination was observed between the 5'NCR and coding regions of different genotypes, implying that the sequence of subgenomic regions such as the 5'NCR can be used to deduce virus genotype. The distribution of polymorphic sites within the 5'NCR is used to propose improved oligonucleotide primers for virus detection and quantification that would be equally efficient in detecting RNA of different virus genotypes. The accuracy of two different genotyping methods (RFLP and the line probe assay) based on analysis of sequence polymorphisms in the 5'NCR is predicted from the sequences surveyed to be 97% and 83% respectively for types 1 to 6, with higher accuracies for distinguishing between subtypes 1a/1b, 2a/2b or 3a/3b. Several sites of genotype-specific polymorphism were covariant and maintained the base pairings required for a secondary structure model of the 5'NCR. Other sites of variation suggest minor modifications to this model and have implications for the probable functions of the 5'NCR.
Immunofluorescence detection of new antigen-antibody system (delta/anti-delta) associated to hepatitis B virus in liver and in serum of HBsAg carriers. (1977)

A new antigen-antibody system associated with the hepatitis B virus and immunologically distinct from the HB surface, core, and e systems is reported. The new antigen, termed delta, was detected by direct immunofluorescence only in the liver cell nuclei of patients with HBsAg positive chronic liver disease. At present, the intrahepatic expression of HBcAg and delta antigen appears to be mutually exclusive. No ultrastructural aspect corresponding to the delta antigen could be identified under the electron microscope. delta antibody was found in the serum of chronic HBsAg carriers, with a higher prevalence in patients with liver damage. The nuclear fluorescence patterns of HBcAg and delta antigen were similar; it is only possible to discriminate between the two antigens by using the respective specific antisera.
β‐Actin is not a reliable loading control in Western blot analysis (2006)

Beta-actin is often used as a loading control in Western blot analysis. We analyzed the ability of beta-actin-specific antibodies to recognize differences in protein loading. We found that, at higher total protein loads as required for the detection of low-abundance proteins, beta-actin-specific antibodies failed to distinguish differences in actin protein levels. Diluting the antibody working solution or changing the incubation time had little effect on this phenomenon. This shows that beta-Actin is not a reliable loading control in Western blot analysis. In general, it appeared that, at longer incubation times, antibodies seem to be less able to pick up differences in the level of its target protein.
Regulation of Hepatitis C Virus Translation and Infectious Virus Production by the MicroRNA miR-122 (2010)

miR-122 is a liver-specific microRNA that positively regulates hepatitis C virus (HCV) RNA abundance and is essential for production of infectious HCV. Using a genetic approach, we show that its ability to enhance yields of infectious virus is dependent upon two miR-122-binding sites near the 5' end of the HCV genome, S1 and S2. Viral RNA with base substitutions in both S1 and S2 failed to produce infectious virus in transfected cells, while virus production was rescued to near-wild-type levels in cells supplemented with a complementary miR-122 mutant. A comparison of mutants with substitutions in only one site revealed S1 to be dominant, as an S2 but not S1 mutant produced high virus yields in cells supplemented with wild-type miR-122. Translation of HCV RNA was reduced over 50% by mutations in either S1 or S2 and was partially rescued by transfection of the complementary miR-122 mutant. Unlike the case for virus replication, however, both sites function equally in regulating translation. We conclude that miR-122 promotes replication by binding directly to both sites in the genomic RNA and, at least in part, by stimulating internal ribosome entry site (IRES)-mediated translation. However, a comparison of the replication capacities of the double-binding-site mutant and an IRES mutant with a quantitatively equivalent defect in translation suggests that the decrement in translation associated with loss of miR-122 binding is insufficient to explain the profound defect in virus production by the double mutant. miR-122 is thus likely to act at an additional step in the virus life cycle.
