Software systems like Web crawlers, Web archives or Web caches depend on or may be improved with the knowledge of update times of remote sources. In the literature, based on the assumption of an exponential distribution of time intervals between updates, diverse statistical methods were presented to find optimal reload times of remote sources. In this article first we present the observation th...

One problem many Web users encounter is to keep track of changes of distant Web sources. Push services, informing clients about data changes, are frequently not provided by Web servers. Therefore it is necessary to apply intelligent pull strategies, optimizing reload requests by observation of data sources. In this article an adaptive pull strategy is presented that optimizes reload requests wi...

In this appendix, we describe an initial version of the AFB interface. We specify it as a system-call oriented interface between the operating system and the application programs. We refer to pages in a virtual memory address space by symbolic names like a i and b, although the actual interface will require the use of each page's actual virtual memory address. SAPPs are assigned unique identifi...

Studies were conducted to relate the influence of the physical characteristics, leaf nutrient content and phloem sap amino acid concentration of citrus flush shoots on the densities of various Diaphorina citri life stages. Adult D. citri preferentially selected young shoots for feeding and numbers of D. citri immatures were positively correlated with flush shoot softness. Young flush shoots had...

The citrus disease huanglongbing (HLB), associated with an uncultured bacterial pathogen, is threatening the citrus industry worldwide. A mathematical model of the transmission of HLB between its psyllid vector and citrus host has been developed to characterize the dynamics of the vector and disease development, focusing on the spread of the pathogen from flush to flush (a newly developing clus...

There have been a variety of absorbable and permanent tacks, tack deployment systems, and fasteners developed for the fixation of mesh during laparoscopic ventral hernia repair. The manufacturer recommendation for all systems is for perpendicular deployment of these tacks into the tissue. Achieving this optimal angle with previously developed deployment systems is often challenging and can lead...

Niacin lowers serum cholesterol, low-density lipoprotein, and triglycerides, and it raises high-density lipoprotein. However, most patients experience cutaneous warmth and vasodilation (flush). Acetylsalicylic acid (ASA) can reduce this flush, presumably by decreasing prostaglandin D(2) (PGD(2)) release from macrophages. Here, we show that methylnicotinate induces significant PGD(2) release fro...

Since optimal assignment of tasks in a multiprocessor system is, in almost all practical cases, an NP-hard problem, in recent years some algorithms based on genetic algorithms have been proposed. Some of these algorithms have considered real-time applications with multiple objectives, total tardiness, completion time, etc. Here, we propose a suboptimal static scheduler of nonpreemptable tasks i...

A fundamental assumption in software security is that a memory location can only be modified by processes that may write to this memory location. However, a recent study has shown that parasitic effects in DRAM can change the content of a memory cell without accessing it, but by accessing other memory locations in a high frequency. This so-called Rowhammer bug occurs in most of today’s memory m...

PURPOSE To investigate the clinical efficacy of low-dose chlormadinone acetate (CMA) in prostate cancer patients who suffer from hot flushes that is a major side effect of androgen deprivation therapy. METHODS Our study included 32 prostate cancer patients who had severe hot flush after undergoing hormone therapy for more than 3 months. The average age of the patients was 72.5 years. In the b...
