Recently, electrospinning technology has been widely used as a processing method to make nanofiber sheets (NS) for biomedical applications because of its unique features, such as ease of fabrication and high surface area. To develop a sustained dexamethasone (Dex) delivery system, in this work, poly(ε-caprolactone-co-l-lactide) (PCLA) copolymer with controllable biodegradability was synthesized...

Although sickling and solubility tests and peripheral blood film methods are today available for sickle cell disease screening in Uganda, their reliability and ease of applicability have not been determined. This study was therefore carried out to determine the reliability of sickling and solubility tests and peripheral blood film method for screening for SCD in Uganda. This was descriptive lab...

In a previous paper (Olling 1995, AJ, 110, 591) a method was developed to determine the shapes of dark matter halos of spiral galaxies from an accurate determination of the rotation curve, the flaring of the gas layer and the velocity dispersion in the H I . Here this method is applied to the almost edge-on Scd galaxy NGC 4244 for which the necessary parameters are determined in the accompanyin...

Among the many families of nonperiodic tilings known so far, SCD tilings are still a bit mysterious. Here, we determine the diffraction spectra of point sets derived from SCD tilings and show that they have no absolutely continuous part, that they have a uniformly discrete pure point part on the axis Re3, and that they are otherwise supported on a set of concentric cylinder surfaces around this...

In many larger organizations like internationally operating companies, owners of analytical information systems must frequently cope with change. An important part of this problem is the restructuring of attributes serving as classification categories, so-called dimensions. This pattern language concerns itself with different ways of preparing for and dealing with changes in the real world and ...

Large-scale `1-regularized loss minimization problems arise in high-dimensional applications such as compressed sensing and high-dimensional supervised learning, including classification and regression problems. High-performance algorithms and implementations are critical to efficiently solving these problems. Building upon previous work on coordinate descent algorithms for `1-regularized probl...

Electronic institutions (EIs) define the rules of the game in agent societies by fixing what agents are permitted and forbidden to do and under what circumstances. Autonomic Electronic Institutions (AEIs) adapt their regulations to comply with their goals despite coping with varying populations of self-interested external agents. This paper presents a self-adaptation model based on Case-Based R...

This paper focuses on the mediation between Interactive e-Services (IeS) and channels used during human-organisation interactions. This mediation consists in a succession of service adaptations, changing from an abstract structure to a concrete one. Our contribution is mainly devoted to aspects concerning the Quality of Service (QoS), particularly about instrumentation and measurement issues, a...

For how long will a recommendation model provide adequate recommendations? The answer to this question depends on the kind of model, its underlying data, and the domain among other factors. We analyse four types of models in the news domain on how their predictive performances change. Our observations show that replacing or updating models is necessary to maintain high predictive performance. T...

The calculations of big bang nucleosynthesis depend on a large number of measured parameters. Below you are asked to qualitatively describe the effects of changing some of these parameters. Include a sentence or two to explain each of your answers. (These topics have not been discussed in class, but you are expected to be able to answer the questions on the basis of your readings in Weinberg’s ...
