Effects of Forest Cover Change on Flood Characteristics in the Upper Citarum Watershed

open access: yesJurnal Manajemen Hutan Tropika, 2014
Information on the effect of forest cover changes on streamflow (river discharge) in large-scale catchment is important to be studied. The rate of forest cover change in the Upper Citarum Watershed as a large-scale catchment is high enough to drive ...

Reexamining Ceramic Standardization During Agricultural Transition: A Geometric Morphometric Investigation of Initial – Early Yayoi Earthenware, Japan

open access: yesOpen Archaeology, 2022
The quantifiable and reproducible representation of variability in material culture has continued to play a key role in the elucidation of shifting patterns of production organization in prehistoric archaeology.

Saturation and periodic self-stress in geometric auxetics

open access: yesRoyal Society Open Science, 2022
The auxetic structures considered in this paper are three-dimensional periodic bar-and-joint frameworks. We start with the specific purpose of obtaining an auxetic design with underlying periodic graph of low valency. Adapting a general methodology, we produce an initial framework with valency seven and one degree of freedom.

On-Orbit Geometric Calibration and Accuracy Validation for Laser Footprint Cameras of GF-7 Satellite

open access: yesRemote Sensing, 2022
The Gaofen-7 (GF-7) satellite uses a two-beam laser altimetry system in which each beam is equipped with a laser footprint camera (LFC) to provide geometric processing of the laser footprint images that assist in optical image stereo mapping.

Development strategies for small and medium-sized enterprises with limited investment resources [PDF]

open access: yesSHS Web of Conferences, 2021
The main source of investment resources for small and medium-sized enterprises is their own profit. The dynamic development of these enterprises is possible only with a strategic program aimed at implementing independent discrete measures.

Axonal growth on surfaces with periodic geometrical patterns

open access: yesPLOS ONE, 2021
The formation of neuron networks is a complex phenomenon of fundamental importance for understanding the development of the nervous system, and for creating novel bioinspired materials for tissue engineering and neuronal repair. The basic process underlying the network formation is axonal growth, a process involving the extension of axons from the cell

Geometric Langlands Duality for Periods

open access: yesGeometric and Functional Analysis
Abstract We study conjectures of Ben-Zvi–Sakellaridis–Venkatesh that categorify the relationship between automorphic periods and L-functions in the context of the Geometric Langlands equivalence. We provide evidence for these conjectures in some low-rank examples, by using derived Fourier analysis and the theory of chiral algebras to ...
