The multi-compartment vehicle routing problem with flexible compartment sizes is a variant of the classical in which customers demand different product types and capacity can be separated into compartments each dedicated to specific type. size not fixed beforehand but number limited. We consider two variants for dividing capacity: On one hand discretely divided on other continuously. objective ...

In this work, the largest tributary of South Branch in upper reaches Xiong’an New Area is selected as study area. The impact-based critical areal rainfall indices for early flood warnings are proposed from perspective impacts floods on socio-economic factors. Specifically, four steps, including determination damage-causing discharges, establishment rainfall–discharge relationship, computation a...

background: the intraperitoneal injection is a common method for establishing the experimental animal model infected with parasites. the aim of this study was to investigate if the intraperitoneal injection was another route of trichinella spiralis infection. methods:  from june to july 2015, twenty balb/c mice were intraperitoneally injected with 300 t. spiralis muscle larvae in department of ...

Competition among free branches in the tree canopy is an important factor influencing branch length growth. Therefore, there a need to quantify this competition and understand impact of regression technique on predictive accuracy growth (GFBL) model Larix principis-rupprechtii plantation. This study focused L. plantation Saihanba Mechanized Forest Farm. Five indices based 2176-branch data point...

Water level monitoring is important for understanding the global hydrological cycle. Remotely-sensed indices that capture localized instantaneous responses have been extensively explored for water level reconstruction during the past two decades. However, the potential usage of the Palmer’s Drought Severity Index (PDSI) and El Niño Southern Oscillation (ENSO) indices for water level reconstruct...

The Kuroshio Current intrudes in the bottom layer of the East China Sea continental shelf from the northeast of Taiwan via two bottom branches named the Nearshore Kuroshio Branch Current (NKBC, along the 60 m isobath) and the Offshore Kuroshio Branch Current (OKBC, along the 100 m isobath). However, knowledge on the macrofaunal responses to these bottom branches is limited. This study examined ...

Homing pigeons develop preferred routes when released alone several times from the same site, but they sometimes diverge from their preferred route when subsequently released with another pigeon. Additionally, group flights show a better homing performance than solo flights. But this knowledge is based on studies involving both sexes and lacks analyses of social parameters such as mating or bre...

OBJECTIVE The current investigation examined individual differences in route-learning strategies and their relative demands on visuospatial versus verbal working memory (WM) resources in virtual environments. BACKGROUND Learning new routes is a resource-demanding activity that must often be carried out in conjunction with other concurrent tasks. Virtual environments (VEs) are increasingly bei...
