Self-stabilizing sorting algorithms
… presents an O(nh) fault-tolerant distributed sorting algorithm for a tree network, where n is the number of nodes in the system, and h is the height of the tree. Fault-tolerance is achieved using Dijkstra's paradigm of self-stabilization which is a method of non-masking fault-tolerance …

Sorting by Bounded Permutations
… the length of the permutation, there are several sorting problems such as sorting by block-moves and sorting by reversals whose bounded variants are at least as difficult as the corresponding unbounded problems. For some bounded problems, a strong relationship exists between finding optimal …

Constant Time Sorting and Searching
To study the sorting of real numbers into a linked list on Parallel Random Access Machine model. To show that input array of n real numbers can be sorted into a linked list in constant time using n²/logᶜn processors for any positive constant c. The searching problem studied is locating the interval …

Comparing Interfaces for Image Sorting
Many tasks ask people to make categorization decisions about a large number of items based on images. There are many ways in which this task can be presented to the user, but there is little information available about how the decision technique affects performance. To investigate this topic three …

Ore sorting using microwave irradiation
Automatic ore sorting machines are in common use in the mining industry. These machines generally separate valuable mineral-bearing rocks from waste rocks. At the Premier Diamond Mine in South Africa kimberlite, a diamond-bearing rock is separated from gabbro which is a waste rock. Work had been …

Problems in Sorting and Graph Algorithms
… with respect to a new model for evaluating sorting algorithms. We did an exhaustive search for such algorithms. The second problem concerns a conjecture that every sorting algorithm on some input involves every key in O(log n) comparisons. We give partial results. The third problem concerns …

Robust portfolio construction using sorting signatures
Mean-variance analysis introduced by Harry Markowitz has been criticised in the past mainly due to the counter-intuitive and unstable nature of the resultant portfolios from the optimisation. These disappointing results have been linked to the presence of estimation error in the estimates of the …

Bacterial lipoproteins: sorting mechanisms and biotechnological applications
The mechanism responsible for lipoprotein sorting is conserved among bacterial species. However, the final destination of lipoproteins may vary among species. In some species lipoproteins are surface-exposed while in others they are associated to the outer membrane but facing the periplasm. To …

On neural spike sorting with mixture models
… we are trying to solve is called neural spike sorting in literature. There are three basic objectives of spike sorting. The first is to estimate the number of neurons which contribute to the recorded neural data. The second is to identify the spikes, i.e. the little curves in the recorded …

Investigation of early endosomal sorting and budding
Frühe Endosomen stellen eine wichtige Sortierstation in eukaryotischen Zellen dar. Sie empfangen Transportvesikel von der Plasmamembran und vom Golgi Apparat und sortieren die darin enthaltene membrangebundene und lösliche Ladung zu verschiedenen intrazellulären Organellen. Somit sind Fusion von …

Role of Adaptor Proteins in MPR sorting
Mannose 6-phosphat Rezeptoren transportieren lösliche lysosomale Proteine und sind daher essentiel für die Biogenese des Lysosomes. Sie binden die Enzyme im trans-Golgi Netzwerk und transportieren sie in Endosomen, wo sie aufgrund des niedrigeren pH-Wertes abdissoziieren. Die Rezeptoren kehren …

Quantifying particle sorting in microbubble streaming flows
… achieve tunable, high throughput, size-sensitive sorting and trapping of particles much smaller than the bubble itself. We propose a simple geometric mechanism, based on flow speeds and channel geometry, that reliably predicts the sorting behaviour seen in experiment. It is also shown that an …
