Bacteria employ extracytoplasmic function (ECF) sigma factors for their responses to environmental stresses. Despite intensive research, the molecular dissection of ECF sigma factor regulons has remained a major challenge due to overlaps in the ECF sigma factor-regulated genes and the stimuli that activate the different ECF sigma factors. Here we have employed tiling arrays to single out the EC...
In this paper we describe the formal specification language RASP for expressing fine-grained access control constraints in information systems. The design of the language is motivated by a number of IS case studies which demonstrate the complexity of the access constraints which arise if minimal (need-to-know) access is to be strictly enforced. RASP supports modularity, parameterization, role a...
The UK Refractory Asthma Stratification Programme (RASP-UK) will explore novel biomarker stratification strategies in severe asthma to improve clinical management and accelerate development of new therapies. Prior asthma mechanistic studies have not stratified on inflammatory phenotype and the understanding of pathophysiological mechanisms in asthma without Type 2 cytokine inflammation is limit...
Weight and cardinality constraints constitute a very useful programming construct widely adopted in Answer Set Programming (ASP). In recent work we have proposed RASP, an extension to plain ASP where complex forms of preferences can be flexibly expressed. In this paper, we illustrate an application of these preferences within weight/cardinality constraints. We emphasize, mainly by simple exampl...
With the development of services computing and cloud computing, it has become possible to outsource large databases to database service providers and let the providers maintain the rangequery service. However, some data might be sensitive that the data owner does not want to move to the cloud unless the data confidentiality and query privacy are guaranteed. We propose the Random Space Encryptio...
Gradient structured materials possess good combinations of strength and ductility, rendering the materials attractive in industrial applications. In this research, a surface nanocrystallization (SNC) technique, rotationally accelerated shot peening (RASP), was employed to produce a gradient nanostructured pure Ti with a deformation layer that had a thickness of 2000 μm, which is thicker than th...
Due to unwant overhead in security process of WSNs, the time consumption of each node is very high from authentication, key generation and key distribution phases and hence every data packet experiences the same latency. The efficiency of exchanging the secret key degrades rapidly as a function of external signal interference power and limits its resilience against active attackers. Increases t...
BACKGROUND Despite significant developments in transurethral surgery for benign prostatic hyperplasia, simple prostatectomy remains an excellent option for patients with severely enlarged glands. The objective is to describe our results of robot-assisted simple prostatectomy (RASP) with a modified urethrovesical anastomosis (UVA). METHODS From May 2011 to February 2014, RASP with UVA was perf...
