Effect of chain blockiness on the phase behavior of ethylene‐octene copolymer blends (2009)

Abstract New challenges and opportunities for polyolefin blends arise from the recent introduction of olefin block copolymers (OBCs). In this study, the effect of chain blockiness on the miscibility and phase behavior of ethylene‐octene (EO) copolymer blends was studied. Binary blends of two statistical copolymers (EO/EO blends) that differed in comonomer content were compared with blends of an EO with a blocky EO copolymer (EO/OBC blends). The blends were rapidly quenched to retain the phase morphology in the melt and the phase volumes were obtained by atomic force microscopy (AFM). Two EOs of molecular weight about 100 kg/mol were miscible if the difference in octene content was less than about 10 mol % and immiscible if the octene content difference was greater than about 13 mol %. The blocky nature of the OBCs reduced the miscibility and broadened the partial miscibility window of the EO/OBC blends compared with the EO/EO blends. The EO/OBC blends were miscible if the octene content difference was less than 7 mol % and immiscible above 13 mol % octene content difference. It was also found that the phase behavior of EO/OBC blends strongly depended on blend composition even for constituent polymers of about the same molecular weight. Significantly more demixing was observed in an OBC‐rich blend (EO/OBC 30/70 v/v) than in an OBC‐poor blend (EO/OBC 70/30 v/v). An interpretation based on extractable fractions of the OBC described the major features of the EO/OBC (30/70 v/v) blends. © 2009 Wiley Periodicals, Inc.

The effect of a percolation threshold in the Kozeny-Carman relation (1997)

Abstract One of the most important properties of reservoir rocks, and perhaps the most difficult to predict, is permeability. Laboratory studies have shown that permeability depends on a long list of parameters: porosity, pore size and shape, clay content, stress, pore pressure, fluid type, saturation—a nearly overwhelming complexity. In spite of this, the essential behavior can often be expressed successfully using the remarkably simple Kozeny-Carman (Kozeny, 1927; Carman, 1937, 1956; Bear, 1972; Scheidegger, 1974) relation κ=Bϕ3S2, where κ is the permeability, ϕ is the porosity, S is the specific surface area (pore surface area per volume of rock), and B is a geometric factor.
Pete the Cat and His Magic Sunglasses (2017)

Pete the Cat is having a rare rough day. It starts to look worse when grumpy toad shows up, but when he shares his secret cool, blue, magic sunglasses with Pete things get better. Pete sees the world in a completely new way. He encounters some unhappy friends and shares his cool, blue, magic sunglasses to help them cheer up. Suddenly, Pete crashes his skateboard and his cool, blue, magic sunglasses shatter. Wise owl tells Pete that he does not need the magic sunglasses to see the world in a new way, he just needs to look for the good all around him. Pete takes his advice and sees that the world is a wonderful place. This is a simple story with fun illustrations. It has the same feel as other Pete the Cat books with a nice little moral at the end. It encourages children to look for the good in the world without leaning to heavily on the moral. The illustrations are bright and have a cool cat vibe consistent with Pete the Cat's character. The paper has a nice sheen and durable quality that adds to the brightness of the story. The language each animal uses to express his enjoyment at seeing the world in a new way is fun and can help children learn new expressions. Preschoolers and early elementary children will enjoy this fun read, but it may be too simple for older grades. Although there is nothing new about the story or moral, it is a quick, light read that young children will enjoy.
c‐Rel and p65 subunits bind to an upstream NF‐κB site in human granulocyte macrophage‐colony stimulating factor promoter involved in phorbol ester response in 5637 cells (1997)

To further clarify the complex transcriptional regulation of the human GM-CSF gene, which was extensively investigated in activated T cells, we have studied the role of an upstream NF-kappaB like site in the 5637 non-lymphoid cell line, which derives from a bladder carcinoma and constitutively produces GM-CSF. This sequence, named the A element, has an active role on GM-CSF transcription and is responsive to the tumor promoter PMA in transient transfection experiments. We describe here a heterodimeric binding complex of NF-kappaB subunits (c-Rel and p65) which is identical to the one obtained using the HIV-LTR-kappaB site as recognition sequence and different from the one (c-Rel and p50) observed with nuclear extracts from Mo T-lymphoid HTLV-II infected cells.
A parameter study of stripline-fed Vivaldi notch-antenna arrays (1999)

A parameter study of Vivaldi notch-antenna arrays demonstrates that the wide-band performance of these antennas can be improved systematically. Stripline-fed Vivaldi antennas are comprised of: (1) a stripline-to-slotline transition; (2) a stripline stub and a slotline cavity; and (3) a tapered slot. The impedances of the slotline cavity and the tapered slot radiator combine at the transition to yield an equivalent series impedance on the feedline. The stripline stub can be represented by a series reactance. The resistance and reactance of the antenna impedance yield insights into the effects of various design parameters. In particular, it is found that the minimum operating frequency can be lowered primarily by increasing the antenna resistance through a change of design parameters. However, beyond a limit for each design parameter, the in-band performance begins to deteriorate. Plots of antenna impedance versus frequency for several parameter variations have been obtained by using a full wave method of moments analysis of infinite arrays. These plots provide a means for designers to systematically improve array performance with bandwidths in excess of 6:1 having been achieved.
Multi-core based HEVC hardware decoding system (2014)

In this demo, a scalable HEVC hardware decoder is demonstrated for various applications including UHD. The architecture includes a control logic for multi-core management and flexible in-loop filters that can process boundaries of picture partitions without a separate in-loop filter unit from the pipeline. Two-level parallel processing approach makes the decoder operate in real-time for high-performance applications. The demonstration on FPGA prototype board shows the efficiency of the proposed scalable architecture achieved by multi-core design. The system is estimated to be able to decode UHD video coded by HEVC in real-time.
An electrooptic image storage device using field induced reversible transitions between AFE and FE phases of PLZT ceramics (1974)

Abstract Field induced reversible transitions between AFE and FE phases of PLZT ceramics are considered to realize a high contrast image storage and display device. The proposed field-induced phase transition takes the material from a non-scattering AFE phase to a scattering FE phase, and returns the material to the original AFE phase by the application of a reverse field. The transitions can be accomplished by relatively low electric fields of several kV/cm. The required double hysteresis loops which indicate the reversible phase changes between AFE and FE phases were obtained in the composition of PLZT-7.6/70/30. Typical characteristic features accompanying the phase transitions are explained in terms of the phase relations of PLZT ceramics.

A Decision Making Framework for Dressing Consultant (2007)

The project, Dressing Consultant, aims to provide a system which functions as a personal wearing advisor to help general users choose a correct clothing for occasions. ALCOVE (attention learning covering network) neural network model is used to train the matchmaker as a fashion editor. In addition, image processing techniques are employed at pre-processing stage to obtain the essential data of garments and to build a digital wardrobe for individuals. On the occasions when user has trouble finding an outfit for a special event, what user could do is to make a decision of the style of apparel to the system and let the system go through piece of garments in the digital wardrobe, and the matchmaker will then find several matched pairs. Eventually, the most similarly suitable and matched garments pair is shown in 3D show room. This paper focuses on making decision of correct clothing according to those classifying and matching rules extracted from fashion industry
Sandwiched long-period gratings for simultaneous measurement of refractive index and temperature (2005)

A simultaneous measurement of external refractive-index (RI) and temperature is presented by using a sandwiched structure of long-period gratings (LPGs). An LPG pair with codirectional coupling between the guided mode and a low-order cladding mode acts as a temperature sensor with low RI sensitivity, whereas another in-between LPG which couples the guided mode with a higher order cladding mode performs as an RI sensing element. The experimental results show such an all-LPG structure is not only suitable for use as a compact temperature-compensated RI sensor, but also convenient for fabrication.
An Order-seven Implicit Symmetric Scheme Applied to Second Order Initial Value Problems of Differential Equations (2012)

In this paper, a five-step predictor-corrector method of algebraic order seven is presented for solving second order initial value problems of ordinary differential equations directly without reduction to first order systems. Analysis of the basic properties of the method is considered and found to be consistent, zero-stable and symmetric. Some sample linear and nonlinear problems are solved to demonstrate the applicability of the method. It is observed that the present method approximates the exact solution well when compared with the two existing schemes that solved the same set of problems. Keywords: zero-stability, convergence, consistent, predictor-corrector, error constant, symmetric
Discovery of 5-Arylsulfonamido-3- (pyrrolidin-2-ylmethyl)-1<i>H</i>-indole Derivatives as Potent, Selective 5-HT<sub>6</sub>Receptor Agonists and Antagonists (2004)

5-Arylsulfonylamido-3-(pyrrolidin-2-ylmethyl)-1H-indoles have been identified as high-affinity 5-HT(6) receptor ligands. Within this class, several of the (R)-enantiomers were potent agonists having EC(50) values of 1 nM or less and functioning as full agonists while the (S)-enantiomers displayed moderate antagonist activity.
Nonlinear Shannon Limit in Pseudolinear Coherent Systems (2012)

In this paper, we develop a general first-order perturbation theory of the propagation of a signal in an optical fiber in the presence of amplification and Kerr nonlinearity, valid for arbitrary pulse shapes. We obtain a general expression of the sampled signal after optical filtering, coherent detection, and optimal sampling. We include intrachannel and as well as interchannel nonlinear effects. We obtain simplified expressions in the case in which the accumulated dispersion is high (equivalent to the far-field limit in paraxial optics). This general theory is applied in detail to the special case of spectral-efficient sinc pulses. This exercise shows that the characteristics of the neighboring wavelength-division multiplexed channels are essential in determining the nonlinear impairments.
A Survey over the Security Issues of Bluetooth using Elliptic Curve Cryptography (2016)

In this research paper,the authors are addressing the problem of algorithms for Wireless LAN for Secured Transmission. This research work also proposes an overview of some of the major attacks that Blue tooth has faced over the years along with some possible solutions. The main aim of this research work is to investigate security features of Bluetooth using Elliptic Curve Cryptography(ECC). The ECC is the latest and fastest encryption method which offers stronger security. As it is known that although a vast majority of devices currently now communicates using Bluetooth methodology, the blue tooth security expert provides automatic updates to its security protocol and user privacy protection techniques. Further protection of the device user's personal information becomes the primary aim. The research work also explores the Bucket Brigade Attack on Bluetooth security using Elliptic Curve Cryptography (ECC). Also it is implied that Bucket Brigade Attack(BBA) is one of the amazing solution to the problem of key agreement or key swapping. Further the beauty of this scheme is when two parties who likes to communicate using symmetric key and an Elliptic Curve Cryptography(ECC) an Intruder(Hacker) enters in between a sender and a receiver. This paper is an attempt to implement the ECC after a survey over the current issues on security.
Association of netilmicin Sulphate to poly(Alkylcyanoacrylate) Nanoparticles: Factors Influencing particle delivery Behaviour (1994)

AbstractThe entrapment of Netilmicin sulphate (NTS) in polyalkylcyanoacrylate nanoparticles could be of therapeutic interest particularly in the treatment of infection that localise in the macrophages. In fact, aminoglycosides are excluded from macrophages and therefore represent an ineffective therapy for the treatment of typhoid fever, despite the excellent in vitro activity. In this case the colloidal delivery system ensures the NTS targeting to the macrophages. In this paper it is shown that the various formulation conditions are capable of influencing: trapping capacity, particle size, molecular weight distribution. The nanoparticle preparation was carried out using three different methods in the presence of Tween 80 and Pluronic F68, as non-ionic surfactant. The incorporation method consisting in adding the drug to the polymerisation medium led to very low values of NTS entrapment, in addition, formation of instable suspension was obtained increasing the NTS concentration over 5 mg/ml. The other two methods consisting in the absorption of the drug in the polymeric network of the nanoparticles showed higher NTS entrapment values The presence of the drug in the polymerisation medium influenced both particle size and polymer chain molecular weight, providing an increase in both values. These results indicate that arranging preparation conditions, it is possible to obtain a nanoparticle delivery device presenting the most suitable behaviour as a function of the therapeutic aim and administration route.
The hyaluronan synthesis inhibitor 4-methylumbelliferone exhibits antitumor effects against mesenchymal-like canine mammary tumor cells (2013)

Hyaluronan (HA), a principal constituent of the extracellular matrix (ECM), mediates growth and metastasis of tumor cells. The role of HA in the epithelial-mesenchymal transition (EMT) is well known, and increased ECM remodeling is observed in mesenchymal-like cells. The HA synthesis inhibitor 4-methylumbelliferone (4-MU) is anti-tumorigenic for various malignant tumors. However, the antitumor effect of 4-MU against canine mammary tumor cells that possess a mesenchymal-like phenotype is unclear. We examined the antitumor effect of 4-MU on CF41.Mg mesenchymal-like canine mammary tumor cells. We investigated the influence of 4-MU on the expression of HA synthase (HAS) 1-3 mRNA and observed dose-dependent downregulation of HAS2 mRNA at 24-72 h; in contrast, HAS3 expression was elevated at 24 h. Thus, 4-MU inhibited HA synthesis via HAS2 repression. 4-MU also inhibited cell proliferation and induced apoptosis in the CF41.Mg cells. Our experiments showed that 4-MU-induced apoptosis in CF41.Mg cells involved induction of the pro-apoptotic gene BAX. We also assessed motility and found that 4-MU reduced chemokinesis and chemotaxis in CF41.Mg cells. Our data suggest that 4-MU may serve as a candidate therapeutic agent for the treatment of canine mammary tumors. Since 4-MU exhibits antitumor activity in mesenchymal-like cells, it may also be a useful inhibitor of canine mammary tumor invasion and metastasis.
Diagnostics and Treatment of Metastatic Cancers with Magnetic Nanoparticles (2013)

Cancer is the leading cause of death among people younger than 85 years. One of the most important factors in effective cancer treatment is the detection of cancerous tumor cells in an early stage. Magnetic nanoparticles have the unique ability to specifically target tumor tissue leaving healthy cells intact. These superparamagnetic particles offer great potential in variety of applications in their bare form or with a surface coating and functional group chosen for a specific application. Upon functionalization, MNPs can be used in in vivo and in vitro by application of magnetic field. Magnetic nanoparticles are less toxic, biocompatible and have a shorter relaxation time. Magnetic nanoparticles have been an important class of biomaterials. Magnetic nanoparticles are globular, iron oxide containing particles having large surface to volume ratio, quantum size effect, superparamagnetic character and functional groups for conjugating to multiple diagnostic and therapeutic agents. Magnetic nanoparticles have shown clinical utility in cancer imaging, biomolecular profiling of cancer biomarkers and drug delivery. The knowledge about magnetic nanoparticles has increased tremendously providing great opportunities for improving the management of cancer patients by enhancing the efficiency of detection and efficacy of treatment. The prospects of magnetic nanoparticles in cancer imaging and treatment are reviewed here. These particles are sure to create wonders in the future of nanomedicine.
Antibodies to hepatitis C virus in uremic patients on continuous ambulatory peritoneal dialysis (1991)

The prevalence of antibody to hepatitis C virus (anti-HCV) among 101 uremic patients receiving continuous ambulatory peritoneal dialysis (CAPD) was evaluated using a synthetic peptide-based HCV antibodies enzyme immunoassay. Thirty (29.7%) were found anti-HCV positive. This is significantly higher than 500 unselected paid blood donors (4.2%, P less than 0.0001). Among CAPD patients, anti-HCV positivity was found more frequently in patients who had received frequent and longer duration of hemodialysis previously (40.4% vs. 20.4%, P less than 0.05). These findings suggest that hemodialysis patients have a higher risk of HCV infection. At present, CAPD may be a suitable way to reduce the incidence of HCV infection in uremic patients.
Nanodelivery of parthenolide using functionalized nanographene enhances its anticancer activity (2014)

Advances in anticancer chemotherapy have been hindered by the lack of biocompatibility of new prospective drugs. One significant challenge concerns water insolubility, which compromises the bioavailability of the drugs leading to increased dosage and higher systemic toxicity. To overcome these problems, nanodelivery has been established as a promising approach for increasing the efficacy and lowering the required dosage of chemotherapeutics. The naturally derived compound, parthenolide (PTL), is known for its anti-inflammatory and anticancer activity, but its poor water solubility limits its clinical value. In the present study, we have used carboxyl-functionalized nanographene (fGn) delivery to overcome the extreme hydrophobicity of this drug. A water-soluble PTL analog, dimethylamino parthenolide (DMAPT), was also examined for comparison with the anticancer efficacy of our PTL-fGn complex. Delivery by fGn was found to increase the anticancer/apoptotic effects of PTL (but not DMAPT) when delivered to the human pancreatic cancer cell line, Panc-1. The IC<sub>50</sub> value for PTL decreased from 39 µM to 9.5 µM when delivered as a mixture with fGn. The IC<sub>50</sub> of DMAPT did not decrease when delivered as DMAPT-fGn and was significantly higher than that for PTL-fGn. There were significant increases in ROS formation and in mitochondrial membrane disruption in Panc-1 cells after PTL-fGn treatment as compared to PTL treatment, alone. Increases in toxicity were also seen with apoptosis detection assays using flow cytometry, ethidium bromide/acridine orange/DAPI staining, and TUNEL. Thus, fGn delivery was successfully used to overcome the poor water solubility of PTL, providing a strategy for improving the effectiveness of this anticancer agent.
Quantum Dots in Photonic Crystal Waveguides: From Efficient Single Photon Sources to Deterministic Photon-Photon Interaction (2014)

This Thesis is focused on the study of quantum electrodynamics in photonic crystal waveguides. We investigate the interplay between a single quantum dot and the fundamental mode of the photonic crystal waveguide. We demonstrate experimental coupling eciencies for the spontaneous emission into the mode exceeding 98% for emitters spectrally close to the band-edge of the waveguide mode. In addition we illustrate the broadband nature of the underlying eects, by obtaining coupling eciencies above 90% for quantum dots detuned from the band edge by as far as 20nm. These values are in good agreement with numerical simulations. Such a high coupling eciency implies that the system can be considered an articial 1D-atom, and we theoretically show that this system can generate strong photon-photon interaction, which is an essential functionality for deterministic optical quantum information processing. We present the progress towards the experimental demonstration of such a strong photon-photon nonlinearity. We present the rst signatures of resonant transmission in photonic crystal waveguides and discuss some of the encountered diculties and future directions of the experiments. In the nal part of this Thesis we discuss a novel type of photonic crystal waveguide and show its applications for on-chip quantum information processing. This structure was designed for the ecient mapping of two orthogonal circular dipole transitions to dierent propagation paths of the emitted photon, i.e. exhibits chiral quantum-dot-waveguide coupling. Such a structure is ideally suited for a number of applications in quantum information processing and among others we propose an on-chip spin-photon interface, a single photon transistor, and a deterministic cNOT gate.
Distributed monitoring and resource management for large cloud environments (2011)

Over the last decade, the number, size and complexity of large-scale networked systems has been growing fast, and this trend is expected to accelerate. The best known example of a large-scale networked system is probably the Internet, while large datacenters for cloud services are the most recent ones. In such environments, a key challenge is to develop scalable and adaptive technologies for management functions. This thesis addresses the challenge by engineering several protocols for distributed monitoring and resource management that are suitable for large-scale networked systems. The protocols are evaluated through theoretical analysis, simulation studies and testbed experimentation. The evaluation results show that the protocols achieve their respective design objectives with respect to quality, efficiency, scalability, controllability and adaptability.
