In the dynamic monitoring fixed sample plot of 25 ha coniferous broad-leaved mixed forest in temperate zone Northeast China, we used data from two surveys (2013 and 2018) microtopography plot, mycorrhizal type tree species to explore whether different types single terrain factors will affect radial growth with on a regional scale. We studied adaptability north end Changbai Mountain south slope ...

The purpose of this study was to determine how vulnerable the west coast Aceh Besar, province, Indonesia, is in terms its coastal morphology. This research conducted from August December 2020 and data processing carried out at Geographical Information Systems Laboratory, Faculty Marine Affairs Fisheries, Syiah Kuala University. method used vulnerability index (CVI) with four geological paramete...

A comparison of 4 × 4 multiple-input multiple-output wireless local area network wireless communication characteristics for six different geometrical shapes is investigated. These six shapes include the straight shape corridor with rectangular cross section, the straight shape corridor with arched cross section, the curved shape corridor with rectangular cross section, the curved shape corridor...

With the development of Steel Truss Corridor (STC) toward long-span and gentle development, human-induced vibration often causes large lateral problems time-delay effects STC, which will have a non-negligible impact on dynamic performance STC. In this paper, parametric model proposed by Piccardo is improved, nonlinear equation STC established considering longitudinal–lateral walking force coupl...

In nature, plumes usually enter the coastal ocean after they leave estuary, and most of them interact with continental shelf slope. To understand plume dynamics, laboratory experiments were carried out on a rotating table to simulate evolution over sloping bottom. We modified reduced gravity g’ , Coriolis parameter f slope α study their impacts characteristics freshwater fate, used optical thic...

[1] In soil‐mantled steeplands, soil motions associated with creep, ravel, rain splash, soil slips, tree throw, and rodent activity are patchy and intermittent and involve widely varying travel distances. To describe the collective effect of these motions, we formulate a nonlocal expression for the soil flux. This probabilistic formulation involves upslope and downslope convolutions of land sur...

PURPOSE This study aimed to identify time-dependent prognostic factors and demonstrate the time-dependent effects of important prognostic factors in patients with advanced gastric cancer (AGC). MATERIALS AND METHODS We retrospectively evaluated 3,653 patients with AGC who underwent curative standard gastrectomy between 1991 and 2005 at the Korea Cancer Center Hospital. Multivariate survival a...
