MathLink is Wolfram Research?s protocol for communicating with the Mathematica Kernel and is used extensively in their own Notebook Frontends. The Mathematica Book insinuates that linking C programs with MathLink is straightforward but in practice there are quite a number of stumbling blocks, in particular in cross-language and cross-platform usage. This write-up tries to clarify the main issues and hopefully makes it easier for software authors to set up Mathematica interfacing in a portable way. 相似文献

This paper presents a semi‐adaptive control approach to closed‐loop medication infusion problems. The rationale underlying this approach is to design a controller that can adapt model parameters with a large impact on the model's fidelity while fixing the remaining parameters at nominal values. In this paper, a control‐oriented model for this purpose is derived via system identification and sensitivity analysis of a low‐order model capturing the direct dose‐response relationship Using the model thus derived, a model‐reference adaptive controller and a composite adaptive controller are designed and compared with each other. In‐silico simulation results using remifentanil's effect on respiratory rate as an example indicate that both controllers can regulate the output at commanded set points.

A distinction is suggested between the notions ‘information tare’, the role of which is played by the signals or letters forming the message, and ‘information’, which may be contained in such messages. It is shown that Shannon's definition of the amount of information is, in fact, the definition of the volume of information tare, whereas the amount of information itself may be measured as the volume of information tare of the maximally compact message used for its recording. This allows one to express both the volume of information tare, H, and the amount of information, B, in the same units of measurement–bits–and for any message B≤H. Some consequences of these views are analysed. 相似文献

This mini review gives an overview of the synthesis of polyurethanes and polyesters with pendant hydroxyl groups performed mainly in our group. Significant for the synthesis of most of these polymers with hydroxyl‐functional side groups is that no protection groups are needed. This is realised either by generating the OH group during polymer synthesis—demonstrated by the preparation of hydroxyl‐functional polyurethanes from dicarbonate monomers and diamines—or by using catalysts which discriminate between primary and secondary OH groups—demonstrated by the synthesis of hydroxyl‐functional polyesters based on malic acid using scandium triflate as catalyst. In addition, the potential of carbonate couplers for the synthesis of multifunctional polyurethane is presented. The application of such multifunctional polyurethanes as antimicrobial polymers and coatings is briefly discussed. Copyright © 2012 Society of Chemical Industry 相似文献

Recently, (Ga1-xZnx)(N1-xOx) has gained widespread attention as a comparatively high efficiency photocatalyst for visible-light-driven overall water splitting. Despite significant gains in efficiency over the past several years, a majority of the photogenerated carriers recombine within bulk powders. To improve the photocatalytic activity, we used an epitaxial casting method to synthesize single-crystalline, high surface area (Ga1-xZnx)(N1-xOx) nanotubes with ZnO compositions up to x=0.10. Individual nanotubes showed improved homogeneity over powder samples due to a well defined epitaxial interface for ZnO diffusion into GaN. Absorption measurements showed that the ZnO incorporation shifts the absorption into the visible region with a tail out to 500 nm. Gas chromatography (GC) was used to compare the solar water splitting activity of (Ga1-xZnx)(N1-xOx) nanotubes (x=0.05–0.10) with similar composition powders. Cocatalyst decorated samples were dispersed in aqueous solutions of CH3OH and AgO2CCH3 to monitor the H+ reduction and H2O oxidation half reactions, respectively. The nanotubes were found to have approximately 1.5–2 times higher photocatalytic activity than similar composition powders for the rate limiting H+ reduction half reaction. These results demonstrate that improvements in homogeneity and surface area using the nanotube geometry can enhance the photocatalytic activity of GaN:ZnO for solar water splitting. 相似文献

Reactive oxygen species (ROS) are continuously produced in aerobic organisms. Overproduction of ROS is known to play a crucial role in the pathogenesis of many cardiovascular diseases, including atherosclerosis and hypertension. Superoxide dismutase (SOD) and catalase (CAT) play critical roles on the removal of excess ROS. In the present study, we investigated the antioxidant activity of cyanidins from ogapy (Acanthopanax divaricatus var. albeofructus, ADA) fruits against oxidative stress in hydrogen peroxide (H2O2)-pretreated U937 macrophages, and explored the plausibility of the therapeutic effect of cyanidins on atherosclerosis. As a result, H2O2 generation and lipid peroxidation induced by H2O2-pretreatment was decreased by the treatment of cyanidins in U937 macrophages. In addition, increased activity of SOD and CAT was shown in H2O2-pretreated cells when treated with cyanidins. Overall, the results obtained in this study showed that cyanidin 3-galactoside and cyanidin 3-lathyroside from ADA fruits could protect macrophages against the damaging effects of H2O2 treatment. 相似文献
