Computers with hard-disk storage and networks with dynamic spectrum access illustrate resources that allow fragmented items – in these examples, items are files and spectra, respectively. In our discrete model of such systems, the resource is a sequence of slots. There is a queue of items awaiting allocations of the resource; the queue is served in FIFO order. Specified for each item are the nu...

Upon completion of the human and mouse genome sequences, world-wide sequencing capacity will turn to other complex organisms. Current strategies call for many of these genomes to be incompletely sequenced. That is, holes will remain in the known sequence, and the relative order and orientation of the known sequence fragments may not be determined. Sequence comparison between two genomes of this...

We attempted to identify the mechanisms responsible for adverse e€ects of habitat fragmentation on brown treecreepers (Climacteris picumnus) inhabiting eucalyptus woodland in northeastern New South Wales, Australia by comparing demography and foraging ecology of birds in highly fragmented and relatively unfragmented landscapes. In particular, we investigated three possibilities, disrupted dispe...

—We used underwater visual census (UVC) to characterize fish assemblages among estuaries with different degrees of fragmentation on Andros Island, Bahamas. Estuaries were classified a priori into four fragmentation categories: totally fragmented (no surface water connectivity to the ocean), partially fragmented, minimally fragmented, and unfragmented (unimpeded surface water connectivity throug...

In this paper we argue that landscape spatial structure is o f central importance in understanding the effects o f f ragmentat ion on populat ion survival Landscape spatial structure is the spatial relationships among habitat patches and the matr ix in which they are e m ~ l d e ~ Many general models o f subditrlded populat ions make the assump. tions that (1) all habitat patches are equivalent...

Motivated by recent findings of enhanced species survival when fragmented habitats are reconnected through narrow strips land [S. Pimm, and C. N. Jenkins, Am. Sci. {\bf 107}(3), 162 (2019).], we study the effect a corridor connecting two square regions on time three models exhibiting extinction/survival phase transitions: basic contact process (CP), diffusive process, two-species symbiotic (2SC...

One of the most fundamental achievements in infants' cognitive development is their appreciation that material objects exist permanently in space and time. Recent findings suggest that infants fail to identify fragmented material objects as continuously existing items. Four experiments assessed 8-12-month-old infants' ability to further represent an object that was fragmented into two or more p...

P-glycoprotein, encoded by the multidrug resistance (MDR)-1 gene, expels various drugs from cells resulting in multidrug resistance. We found previously that interleukin-2, a lymphocyte-activation cytokine, induces P-glycoprotein expression on lymphocytes. Lymphocyte activation involves adhesion with the extracellular matrix, such as hyaluronan, through adhesion molecules on lymphocytes. We inv...

The integration of fragmented data seriously impedes the distributed data exploitation in content-centric networks. It requires dealing with the dynamics, semantics and efficiency problems in the data integration. In this paper, a novel scheme is proposed to integrate the fragmented named data into semantic data sequences which can quickly response to users in the content-centric network. In or...
