The vitamin D3 24-hydroxylase gene (CYP24) is one of the most strongly induced genes known. Despite this, its induction by the hormone 1alpha,25-dihydroxyvitamin D3 (1alpha,25OH2D3) has been characterized only partially. Therefore, we monitored the spatio-temporal, 1alpha,25OH2D3-dependent chromatin acetylation status of the human CYP24 promoter by performing chromatin immunoprecipitation (ChIP) assays with antibodies against acetylated histone 4. This was achieved by performing PCR on 25 contiguous genomic regions spanning the first 7.7 kb of the promoter. ChIP assays using antibodies against the 1alpha,25OH2D3 receptor (VDR) revealed that, in addition to the proximal promoter, three novel regions further upstream associated with VDR. Combined in silico/in vitro screening identified in three of the four promoter regions sequences resembling known VDREs and reporter gene assays confirmed the inducibility of these regions by 1alpha,25OH2D3)=. In contrast, the fourth VDR-associated promoter region did not contain any recognizable classical VDRE that could account for the presence of the protein on this region. However, re-ChIP assays monitored on all four promoter regions simultaneous association of VDR with retinoid X receptor, coactivator, mediator and RNA polymerase II proteins. These proteins showed a promoter region-specific association pattern demonstrating the complex choreography of the CYP24 gene promoter activation over 300 minutes. Thus, this study reveals new information concerning the regulation of the CYP24 gene by 1alpha,25OH2D3, and is a demonstration of the simultaneous participation of multiple, structurally diverse response elements in promoter activation in a living cell.

Comparison meaningful functions acting on some real interval E are completely described as transformed coordinate projections on minimal invariant subsets. The case of monotone comparison meaningful functions is further specified. Several already known results for comparison meaningful functions and invariant functions are obtained as consequences of our description. [less ▲]

In this paper we describe our experience using Coordinated Atomic Actions (CAAs) to design a control system for a medical treatment, which has high reliability requirements. The “Fault-Tolerant Insulin Pump Therapy” is based on the Continuous Subcutaneous Insulin Injection technique involving different sensors and actuators in order to enable continued execution of the treatment, as well as detect faults in it. Precisely that is the challenge raised by this example, to design a control system that maintains the delivery of insulin even in the presence of a large number and variety of hardware and software failures. The implementation of this control system has been made in Java using an extension of the DRIP framework, that ensures the reliability properties of systems designed using CAAs. [less ▲]

Complex fault-tolerant distributed systems have a growing need of new functional and quality requirements. An immediate consequence of this is an increasing need of new methods for developing complex fault-tolerant distributed applications. Coordinated Atomic Actions (CAAs), making use of exception handling mechanism, offer an approach to ensure the needed requirements of reliability, availability and fault tolerance. Unfortunately, there is currently no method for the high-level modeling of such systems. In this paper, in order to offer an instrument for modeling exception handling, we propose a UML2.0 Platform Independent Profile for CAAs that allows designers to describe complex systems separating the specification from the implementation on a specific technology platform.

This paper analyses the rules regarding the internet-based exercise of shareholder rights for public corporations incorporated in Canada, France, Germany, the U.S. (DelGCL & RMBCA), the UK and Switzerland. The traditional doctrine associates information, communication and voting with shareholder meetings. In addition, shareholder meetings regularly prompt reviews of management's activities exercised on behalf of shareholders by accountants or the judiciary. The analysis reveals that the current regimes of shareholder meetings merely provide for voting and information in the context of a digital environment, while communication and review is usually not replicated. The lack of all functions of traditional shareholder meetings is one reason of why exclusively virtual shareholder meetings have not gained widely spread acceptance across jurisdictions. Another reason is that a well-fitting design for the web-based exercise of shareholder rights does not yet exist. Thus, the paper develops an advisable design of Virtual Shareholder Meetings that replicates all for functions of traditional shareholder meetings, while it is likely to reduce shareholder apathy at the same time. It argues that enabling more frequent opportunities for voting is the logical consequence of the developments of continuous disclosure requirements and continuous buy/hold/sell-decisions by market participants. Therefore, the virtual exercise of shareholder rights should be achieved through (1) liberalizing currently existing legislative and practical barriers, and in particular, time and place restrictions on shareholder meetings; (2) re-integrating analyst and institutional investor meetings in the process of shareholder meetings, and (3) substituting for the traditional face-to-face accountability of managers to shareholders through specific electronic means. The latter involves, specifically, the use of RSS-Feed and XBRL-technologies for gathering and evaluating information, the use of the company's website as the central communication platform for management to shareholders and shareholders to shareholders, and the election of an independent shareholder rights manager (firm) by the shareholder body with procedural, technical, and organizational authority for organizing the exercise of shareholder rights. Ideally, the blueprint presented herein achieves the harmonization of voting behavior and market reactions, thereby furthering market efficiency. [less ▲]

To extend the classical Shannon entropy to non-additive measures, Marichal recently introduced the concept of generalized entropy for discrete Choquet capacities. We provide a first axiomatization of this new concept on the basis of three axioms: the symmetry property, a boundary condition for which the entropy reduces to the Shannon entropy, and a generalized version of the well-known recursivity property. We also show that this generalized entropy fulfills several properties considered as requisites for defining an entropy-like measure. Lastly, we provide an interpretation of it in the framework of aggregation by the discrete Choquet integral. [less ▲]

More than two years of data of the champ satellite mission is available and the usage of the energy balance approach for global gravity field recovery has been successfully implemented by several groups around the world. This paper addresses two important aspects of the data processing. First, high-quality gravity recovery requires numerical differentiation of kinematic positions. Two methods are investigated using simulated and real dynamic data. It is shown that a third order Taylor differentiator is sufficient to reach good results. Second drift due to the accelerometer bias has to be corrected. Two possible approaches are discussed: cross-over calibration on the one hand calibration w.r.t. a reference model on the other hand. Currently the crossover calibration fails due to the insufficient accuracy of the crossover determination whereas the calibration w.r.t. a reference model gives good results. [less ▲]
