In this paper, we propose a privacy-preserving variant of Bloom-filters. The Bloom-filter has many applications such as hash-based IP-traceback systems and Web cache sharing. In some of those applications, equipping the Bloom-filter with the privacy-preserving mechanism is crucial for the deployment. In this paper, we propose a cryptographically secure privacy-preserving Bloom-filter protocol. ...

Bloom filters are widely used although not always optimal. Notably in application areas where false negatives are bearable, other techniques can clearly be better. This master thesis shows that at least for a specific area in the parameter space Bloom filters are significantly outperformed even by trivial methods. We provide an analysis, show that many application areas where Bloom filters are ...

Bloom filters are a randomized data structure for membership queries dating back to 1970. Bloom filters sometimes give erroneous answers to queries, called false positives. Bloom analyzed the probability of such erroneous answers, called the false-positive rate, and Bloom’s analysis has appeared in many publications throughout the years. We show that Bloom’s analysis is incorrect and give a cor...

occurances of cyanobacterial bloom typically appear in eutrophic lakes which either have been affected by anthropogenic nutrient loading or are naturally rich in nutrients. microcystis blooms have been reported all over the world in freshwater ecosystems mainly due to increased population which results in increased the waste water production. the aim of this study was to recognize the basic re...

Bloom filter (BF) is a space-efficient data structure that represents a large set of items and supports efficient membership queries. It has been widely proposed to employ Bloom filters in the routing entries so as to facilitate data-centric routing in network applications. The existing designs of Bloom filters, however, cannot effectively support in-network queries. Given a query for a data it...

In late May, 2007, a drinking water crisis took place in Wuxi, Jiangsu Province, China, following a massive bloom of the toxin producing cyanobacteria Microcystis spp. in Lake Taihu, China's third largest freshwater lake. Taihu was the city's sole water supply, leaving approximately two million people without drinking water for at least a week. This cyanobacterial bloom event began two months e...

Adult western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), were most abundant on flower clusters of apple, Malus × domestica Borkhausen, from king bloom to full bloom. Low numbers of thrips remained on the clusters after petal fall as fruit enlarged. Thrips larvae peaked in numbers after densities of adults had peaked, usually by petal fall. Two staining proce...

High-throughput pyrosequencing of SSU rDNA genes was used to obtain monthly snapshots of eukaryotic and bacterial diversity and community structure at two locations in Lake Texoma, a low salinity lake in the south central United States, over 1 year. The lake experienced two disturbance events (i) a localized bloom of Prymnesium parvum restricted to one of the locations that lasted from January ...

In 2011, Lake Erie experienced the largest harmful algal bloom in its recorded history, with a peak intensity over three times greater than any previously observed bloom. Here we show that long-term trends in agricultural practices are consistent with increasing phosphorus loading to the western basin of the lake, and that these trends, coupled with meteorological conditions in spring 2011, pro...

In “Empathy and its discontents” Bloom (2017: see also Bloom, 2016) argues that we should abandon empathy as a moral compass in favor of compassion. Bloom’s central premise is that empathy is narrow in its focus on single identified individuals, biased in that it favors the in-group, and can be used as a tool to motivate us to do things that are not optimally effective, or even destructive (e.g...
