Temperature memory effect in amorphous shape memory polymers (2014)

Temperature memory effect (TME) refers to the ability of shape memory polymers (SMPs) to memorize the temperature at which pre-deformation was conducted. In the past few years, this TME was experimentally demonstrated by comparing the applied programming temperature (Td) with a characteristic recovery temperature (Tc), which corresponds to either the maximum recovery stress or free recovery speed. In these well-designed experiments, Tc was observed to be close to Td, which is consistent with the intuitive understanding of 'memorization'. However, since the polymer recovery behavior has been proved to be strongly dependent on various programming and recovery conditions, a new question that whether Tc is always equal to Td in any thermo-temporal conditions remains to be addressed. In this paper, we answered this question by examining the free recovery profile of an acrylate based amorphous SMP. The recovery Tc, which is the temperature with the maximum recovery speed, versus the recovery temperature is shown to be strongly dependent on both programming and recovery conditions. Their detailed influence could be explained by using the reduced time. During a thermomechanical working cycle of SMPs, in addition to the Td, any other thermo-temporal conditions, such as the holding time (th), cooling rate, recovery heating rate (q), etc., can affect the observed Tc by changing the reduced programming or recovery time. In this manner, the relationship between Tc and Td is not uniquely determined. Besides, the TME in SMPs can only be achieved within a given temperature range. Both onset and offset of this temperature range are shown to be influenced by the programming history, but are independent of the recovery conditions.

Differential protein expression by <b><i>Porphyromonas gingivalis</i></b> in response to secreted epithelial cell components (2005)

The human oral pathogen Porphyromonas gingivalis colonizes the gingival crevice and invades gingival epithelial cells. Multidimensional capillary high-performance liquid chromatography coupled with tandem mass spectrometry and two-dimensional gel electrophoresis were used to analyze the proteome of P. gingivalis as it adapts to a set of experimental conditions designed to reflect important features of an epithelial cell environment. 1014 proteins (46% of the total theoretical proteome) were identified in four independent analyses; 479 of these proteins showed evidence of differential expression after exposure of P. gingivalis to either conditioned epithelial cell growth medium or control conditions: i.e., they were only detected under one set of conditions. Moreover, 276 genes annotated as hypothetical were found to encode expressed proteins. Among the proteins up-regulated in the presence of epithelial cell components were a homolog of the internalin proteins of Listeria monocytogenes and subunits of the ATP-dependent Clp protease complex. Insertional inactivation of clpP, encoding the Clp proteolytic subunit, resulted in approximately a 50% reduction in invasion of P. gingivalis. These results suggest that adaptation to an epithelial cell environment induces a major shift in the expressed proteome of the organism. Furthermore, ClpP, that is up-regulated in this environment, is required for optimal invasive activity of P. gingivalis.
Electro-Cementation of a Marine Clay Induced By Electrokinetics (2002)

This study is directed to using electrokinetic processes for strengthening marine sediments in order to enhance the performance of skirted foundations. This paper studies the electrocementation that occurs during the electrokinetic treatment of a highly saline marine clay. The influence of electrokinetics on the soil structure is characterized by changes in the pore size distributions determined by mercury intrusion porosimetry. The porosity of the treated soil samples was significantly lower, and the pore diameters were significantly smaller than in of the untreated soil samples. The plasticity characteristics of treated soil were also changed after electrokinetic treatment; this is attributable to the electrokinetically enhanced grouping of clay particles into aggregates due to the presence of cementing agents and changes in type and concentration of ions in the soil pore water. The amounts of iron oxide and calcium carbonate, both well-known cementing agents in soil, increased after electrokinetic treatment; this increase contributes to the increase in soil shear strength and decrease in soil pore size. The results of CEC and glycol retention tests indicated that the surface charge of clay particles at the anode sides was reduced after electrokinetic treatment, leading to stronger interparticle bonds.
Chloro boron subphthalocyanine and its derivatives: dyes, pigments or somewhere in between? (2010)

Nine derivatives of chloro boron subphthalocyanine (Cl-BsubPc, 1) have been synthesized and characterized. Seven dimers of Cl-BsubPc have been synthesized by reaction with biphenol (2a), bisphenol A (2b), bisphenol F (2c), bisphenol O (2d), bisphenol P (2e), bisphenol S (2f) and bisphenol Z (2g). For comparison two monomeric phenoxy- (3a) and 4-methylphenoxy (3b) BsubPcs have also been synthesized. Crystals were grown for dimer 2c, whereas all attempts to grow crystals of the remaining dimers resulted in the formation of molecular glasses or amorphous precipitates. Analysis on the structure of 2c suggests that the rigidity and aromatic nature of the central bisphenolic directs the crystal packing. The solubility of the BsubPc dimers in a variety of common organic solvents was measured and compared to that of Cl-BsubPc (2) and monomers 3a and 3b. We have defined ranges for classifying BsubPc derivatives based on their solubility in these solvents: pigment < or = 1 x 10(-8) M, 1 x 10(-3) M < or = pigment-like > 1 x 10(-8) M, 1 x 10(-2) M < or = dye-like > 1 x 10(-3) M, and dye > 1 x 10(-2) M. From this Cl-BsubPc (1) and compounds 2a, 2b, 2c, 2e and 2g are pigment-like while compounds 2d, 2f, 3a and 3b are dye-like. None are exclusively pigments or dyes. In this first approximation of this dye versus pigment classification we have not considered other processes besides solvation which could be undesirable such as polymorphic changes or Ostwald ripening. We have concluded that derivatization of Cl-BsubPc (1) with bisphenols and phenols can be used to control the solubility of BsubPc derivatives. We have also concluded that Cl-BsubPc (1) should not be considered a dye rather is pigment-like in its solubility.

MAP-Me: Managing Anchor-less Producer Mobility in Information-Centric Networks (2016)

Mobility has become a basic premise of network communications, thereby requiring a native integration into 5G networks. Despite the numerous efforts to propose and to standardize effective mobility management models for IP, the result is a complex, poorly flexible set of mechanisms. The natural support for mobility offered by ICN (Information Centric Networking), makes it a good candidate to define a radically new solution relieving limitations of traditional approaches. If consumer mobility is supported in ICN by design, in virtue of its connectionless pull-based communication model, producer mobility is still an open challenge. In this work, we propose MAP-Me, an anchor-less solution to manage micro mobility of content producer via ICN name-based data plane, with support for latency-sensitive applications. First, we analyze MAP-Me performance and provide guarantees of correctness and stability. Further, we set up a realistic simulation environment in NDNSim 2.1 for MAP-Me evaluation and comparison against existing solutions: either random waypoint and trace-driven car mobility patterns are considered under 802.11 radio access. Results are encouraging and highlight the superiority of MAP-Me in terms of user performance and of network cost metrics.
An improved instruction cache replacement algorithm (2006)

Caches are commonly used in DSP architecture, as an alternative for fast on-chip memory, to improve performance by reducing the average memory access latencies. In this paper we propose a new approach for instruction cache performance enhancement, utilizing a-priori knowledge of the program flow to improve the common used LRU replacement algorithm. To improve replacement decision in set-associative caches, we develop a new profile-based algorithm that predicts which code-block will be reused. The proposed algorithm enables the user to affect the cache performance by combining existing LRU hardware and cache dedicated software commands. Simulation results on Starcore's SC140e DSP platform show 2-5% cycle times improvement over the LRU policy for MPEG4 application. Further significant improvement can be achieved when using memories with longer access latencies.
A Multi-criteria Model for Planning and Fine-Tuning Distributed Scrum Projects (2011)

Distributed software development is a fact of life for many projects. It is well established that distance makes difficult to interact and to cooperate effectively. Scrum emphasizes communication, reduces coordination and control overhead; therefore it has enormous potential to help the management of distributed projects and has been increasingly used. Successfully managing the combined use of DSD and Scrum is a complex task and it requires carefully planning. Despite the importance and complexity of this type of problem, there seems to be a lack of reports, in the literature, of models that could support project managers dealing with these decision contexts. This paper presents a multi-criteria decision model for planning and fine-tuning such project plans. This model was developed using cognitive mapping and MACBETH (Measuring Attractiveness by a Categorical Based Evaluation Technique). The application of the model is demonstrated, followed by conclusion and remarks about future work.
Automatic Selection of Methods for Solving Stiff and Nonstiff Systems of Ordinary Differential Equations (1983)

This paper describes a scheme for automatically determining whether a problem can be solved more efficiently using a class of methods suited for nonstiff problems or a class of methods designed for stiff problems. The technique uses information that is available at the end of each step in the integration for making the decision between the two types of methods. If a problem changes character in the interval of integration, the solver automatically switches to the class of methods which is likely to be most efficient for that part of the problem. Test results, using a modified version of the LSODE package, indicate that many problems can be solved more efficiently using this scheme than with a single class of methods, and that the overhead of choosing the most efficient methods is relatively small.
Mutual interactions between flavonoids and enzymatic and transporter elements responsible for flavonoid disposition via phase II metabolic pathways (2012)

Flavonoids, existing mainly as glycosides in nature, have multiple "claimed" beneficial effects in humans. Flavonoids are extensively metabolized in enterocytes and hepatocytes by phase II enzymes such as UGTs and SULTs to form glucuronides and sulfates, respectively. These glucuronides and sulfates are subsequently excreted via ABC transporters (e.g., MRP2 or BCRP). Therefore, it is the interplay between phase II enzymes and efflux transporters that affects the disposition of flavonoids and leads to the low bioavailability of flavonoid aglycones. Flavonoids can also serve as chemical regulators that affect the activity or expression levels of phase II enzymes including UGTs, SULTs and GSTs, and transporters including P-gp, MRP2, BCRP, OATP and OAT. In general, flavonoids may exert the inhibitory or inductive effects on the phase II enzymes and transporters via multiple mechanisms that may involve different nuclear receptors. Since flavonoids may affect the metabolic pathways shared by many important clinical drugs, drug-flavonoid interaction is becoming an increasingly important concern. This review article focused on the disposition of flavonoids and effects of flavonoids on relevant enzymes (e.g. UGTs and SULTs) and transporters (e.g. MRP2 and BCRP) involved in the interplay between phase II enzymes and efflux transporters. The effects of flavonoids on other metabolic enzymes (e.g. GSTs) or transporters (e.g. P-gp, OATP and OAT) are also addressed but that is not the emphasis of this review.
Hybrid optimisation technique for radiotherapy treatment planning (2002)

Presents an optimisation strategy, based on a hybrid multi-objective genetic algorithm, to automate the planning of traditional radiotherapy treatment. The optimisation algorithm is formulated around the concept of Pareto optimality to exploit a population based search procedure thereby considering each of the objectives independently. It explores the solutions belonging to the Pareto optimal set prior to concentrating on the best regions of the search space. Once the Pareto optimal set has been determined, a posteriori articulation of the objectives is used to provide the clinicians with a few alternative solutions, all of them non-dominated and therefore mathematically optimal, leaving the final decision to the clinicians.
Effect ofEscherichia coli biomass composition on central metabolic fluxes predicted by a stoichiometric model (1998)

The amino acid composition of proteins and the fatty acid composition of the cell membranes were measured in Escherichia coli growing exponentially in batch culture on glucose, succinate, glycerol, pyruvate, and acetate, and growing under continuous culture conditions on glucose at dilutions rates equivalent to the growth rates of the batch cultures. Although the fatty acid composition of the membranes did change significantly with carbon source and dilution rate, the amino acid content of proteins did not change significantly under either condition. A previously developed stoichiometric model of metabolism was used to calculate the fluxes through the metabolic reactions and to determine their sensitivity to changes in fatty acid and amino acid composition.
THE NEW MUSICAL IMAGINARY: DESCRIPTION AS DISTRACTION IN NEW MUSIC (2019)

Abstract In her book The Philosophical Imaginary , Michèle Le Doeuff claims philosophers use imagery precisely where their argument is at its weakest in order to provide an indistinct rhetorical space which cannot be clearly judged or criticised. Using Le Doeuff's framework, I examine programme notes: descriptive writing from programmes and grant applications that often tie the music to an extra-musical source of meaning. I point out instances where what is at stake in the work shifts from place to place, performing a determined meaning for the genre's outsiders, but indicating semantic superfluity to insiders who will tangibly judge the music on search committees and grant panels. After discussing genre theory and the history of new music, I argue that this imagery has a deeper social function: to gain social capital by performing diversity while maintaining the cultural power afforded by the genre's roots in hegemonic formalism.
684. Expanded Parvoviral Replicons as Novel Nonviral Vectors for Cancer Gene Therapy (2004)

Gene therapy is an appealing approach to the treatment of human malignancies but significant barriers exist. The use of viral gene therapy vectors is limited due to immunogenicity and toxicity. Nonviral gene transfer systems achieve only low transduction efficiencies. Autonomous parvoviruses are known for their oncotropism and oncosuppressive potential. In addition, recombinant parvoviruses provide high level transgene expression. We therefore developed and optimized parvoviral replicon vectors based on the autonomous parvovirus Minute Virus of Mice (MVMp) and MVMp/EBV (Epstein Barr virus) hybrid vectors. The use of parvoviral replicon vectors will take advantage of the tumor cell-specific cytotoxicity of parvoviruses. Gene delivery of these replicons as SPLP-liposomes will be nontoxic and non-immunogenic allowing repetitive administration. Transgene size, normally limited by inefficient encapsidation of recombinant parvoviruses exceeding a total size of 106% of the wildtype, is not limited in these parvoviral replicon vectors. The parvoviral genome is excised, replicated and expressed in tumor cells resulting in high plasmid copy numbers and high-level transgene expression. Comparison to other highly potent expression vectors, replicative and non-replicative, showed the desirable characteristics of parvoviral replicon vectors. We expect high level cytotoxicity on tumor cells with major bystander effects by using these MVMp-based replicon vectors for expression of the human sodium iodide symporter gene (hNIS) and the Gibbon ape leukaemia virus fusogenic membrane glycoprotein gene (Galv-FMG). Both of these therapeutic genes have proved their strong antitumoral potential in different tumor-models in the past. By packaging these therapeutic MVMp-replicons in SPLP-liposomes we expect a highly efficient vector for cytoreductive cancer gene therapy. Results: MVMp and MVMp/EBV-hybrid replicon vectors containing the marker genes CEA, luciferase and GFP and the therapeutic transgenes Galv-FMG and hNIS have been cloned. Excision and replication of parvoviral DNA has been shown as early as 24 h after transfection. High-level transgene expression in different cell lines was achieved. Excision, replication and transgene expression has been shown up to an increase of the parvoviral genome size of 355% of the wildtype. Comparison to CMV-promoter driven replicative and non-replicative expression vectors showed higher and longer transgene expression levels by the parvoviral replicon vectors. Transgene expression by MVMp and MVMp/EBV-hybrid vectors increased over time in dependence of the susceptibility of the cell line towards MVMp and EBV. Parvoviral replicons containing Galv-FMG were shown to have a very strong cytotoxic potential resulting in an almost complete destruction of susceptible cell layers. Transduction of cells with hNIS expressing parvoviral replicon vectors resulted in high level 125I-uptake.
Localization of pestiviral envelope proteins E(rns) and E2 at the cell surface and on isolated particles. (1999)

The glycoproteins E(rns) of classical swine fever virus (CSFV) and E(rns) and E2 of bovine viral diarrhoea virus (BVDV) are shown to be located at the surface of infected cells by the use of indirect immunofluorescence and by cytofluorometric analysis. The positive immunostaining of the cell surface was further analysed by immunogold electron microscopy and it could be shown that only extracellular virions were labelled. Gold granules were not seen at the cellular plasma membrane. In contrast to BVDV E2, the CSFV E2 of virions sticking to the plasma membrane was not accessible to the respective monoclonal antibodies. However, CSFV particles isolated from culture supernatant were able to bind both monoclonal anti-E(rns) and anti-E2 antibodies. For CSFV and BVDV, binding of anti-E(rns) antibodies to the virions was more pronounced than that of anti-E2. This finding was unexpected since E2 is considered to be the immunodominant glycoprotein.

Preparation of MgO Protective Layer for AC‐Type Plasma Display Panel by Means of Screen‐Printing (1995)

We studied how to form an protective layer on an ac‐type plasma display panel (PDP) using a screen‐printing method. In our study, we focused on high luminous efficiency and low drive voltage. To raise the luminous efficiency, it is necessary to limit the discharge current. The firing voltage , which is the voltage at which all cells start to discharge, and the sustaining voltage , which is the minimum voltage required for all cells to sustain discharge, have no clear relationship to luminous efficiency. To attain both a higher luminous efficiency and a lower drive voltage, a thinner more crystalline layer is necessary. We found that we could prepare an layer by screen‐printing and sintering fine vapor‐deposited powders of different grain sizes with an liquid binder. An protective layer prepared by this method provided both a low drive voltage and superior luminous efficiency 2.8 times higher than that of a sputtered layer. The screen‐printing method thus enables larger ac‐PDPs to be produced at lower cost.
Biologically inspired feature creation for multi-sensory perception (2011)

Automatic feature creation is a powerful tool for identifying and reaching goals in the natural world. This paper describes in detail a biologically-inspired method of feature creation that can be applied to sensory information of any modality. The algorithm is incremental and on-line; it enforces sparseness in the features it creates; and it can form features from other features, making a hierarchical feature set. Here it demonstrates the creation of both visual and auditory features.
