BACKGROUND AND AIMS Fruit set in indeterminate plant species largely depends on the balance between source and sink strength. Plants of these species show fluctuations in fruit set during the growing season. It was tested whether differences in fruit sink strength among the cultivars explained the differences in fruit-set patterns. METHODS Capsicum was chosen as a model plant. Six cultivars w...

Regional groundwater flow systems often contain both strong sinks and weak sinks. A strong sink extracts water from the entire aquifer depth, while a weak sink lets some water pass underneath or over the actual sink. The numerical groundwater flow model MODFLOW may allow a sink cell to act as a strong or weak sink, hence extracting all water that enters the cell or allowing some of that water t...

MAIZE grain yield is shaped by source-sink relationships during filling. Such relations are driven complex metabolic changes, responsive to N availability and not fully understood. Here, the impact of limited sufficient fertilization on interconversions in ear leaf a new maize field-grown hybrid (Tzi8 × Mo17) its critical transition from assimilation remobilization were chronologically investig...

We consider the problem of maximizing the lifetime of a wireless sensor network with a mobile sink. The sink travels at finite speed among a subset of possible sink locations to collect data from a stationary set of sensor nodes. The problem we consider chooses a subset of sink locations for the sink to visit, finds a tour for the sink among the selected sink locations, and prescribes an optima...

The book is not just another " pep talk " on The Kitchen Sink and How to Learn to Like It. Its stated purpose is "to discuss how the ingrained ideas which we have inherited, affect us, as women to-day, and to try to decide whether a woman ought to try to adapt herself to them, or whether it is the old pattern that wants adapting". It seems to be directed mainly to the wife and mother of young a...

Use of mobile devices for data collection in wireless sensor networks (WSNs) has recently drawn much attention. Controlled sink mobility has been shown to be beneficial in energy conservation and lifetime prolongation. In this paper, we propose a multi-hop uneven hierarchical routing protocol (MUHRP) using a controlled mobile sink. We first analyze the performance of MUHRP with a fixed sink nod...

Habitat sinks can attract dispersing animals if high mortality or breeding failure are difficult to detect (e.g., when due to human hunting or pollution). Using a simple deterministic model, we explore the dynamics of such source-sink systems considering three scenarios: an avoided sink, no habitat preference, and an attractive sink. In the second two scenarios, there is a threshold proportion ...
