GEOBIA at the Terapixel Scale: Toward Efficient Mapping of Small Woody Features from Heterogeneous VHR Scenes

open access: yesISPRS International Journal of Geo-Information, 2019
Land cover mapping has benefited a lot from the introduction of the Geographic Object-Based Image Analysis (GEOBIA) paradigm, that allowed to move from a pixelwise analysis to a processing of elements with richer semantic content, namely objects or ...

Home-based internet businesses as drivers of variety [PDF]

open access: yes, 2007
The paper shows how and why Home-Based Internet Businesses are drivers of variety. This paper argues, by means of five theoretical perspectives, that because of the variety HBIBs generate, they contribute to the economy over and above their direct and ...

Isospin and symmetry energy effects on nuclear fragment production in liquid-gas type phase transition region

open access: yes, 2005
We have demonstrated that the isospin of nuclei influences the fragment production during the nuclear liquid-gas phase transition. Calculations for Au197, Sn124, La124 and Kr78 at various excitation energies were carried out on the basis of the ...

Yangian symmetry of boundary scattering in AdS/CFT and the explicit form of bound state reflection matrices [PDF]

open access: yesJHEP 1103:110,2011, 2011
The reflection matrices of multi magnon bound states are obtained explicitely by exploiting the Yangian symmetry of boundary scattering on the Y=0 maximal giant graviton brane.

Management of thyroid tumors diagnosed cytologically as follicular neoplasms in a high-volume center: utility of a scoring system using serum thyroglobulin level, tumor size, ultrasound testing, and cytological diagnosis

open access: yesEndocrine Journal
Managing thyroid nodules diagnosed cytologically as follicular neoplasms (FN) is challenging for patients and clinicians. Gene panel testing was recently introduced to determine the management strategy for FN; however, it is unavailable in Japan. In this

Validation of the 650 MHZ SRF tuner on the low and high beta cavities for PIP-II at 2 K* [PDF]

open access: yesarXiv, 2022
The PIP-II linac will include thirty-six beta=0.61 and twenty-four beta=0.92 650 MHz 5 cell elliptical SRF cavities. Each cavity will be equipped with a tuning system consisting of a double lever slow tuner for coarse frequency tuning and a piezoelectric actuator for fine frequency tuning.

Upper estimates of transition densities for stable-dominated semigroups [PDF]

open access: yesJ. Evol. Equ. 13 (3) (2013) 633-650, 2012
We derive upper estimates of transition densities for Feller semigroups with jump intensities lighter than that of the rotation invariant stable Levy ...

Quantification of Pregenomic RNA and Covalently Closed Circular DNA in Hepatitis B Virus-Related Hepatocellular Carcinoma

open access: yesInternational Journal of Hepatology, 2013
Pregenomic RNA (pgRNA) is generated from covalently closed circular DNA (cccDNA) and plays important roles in viral genome amplification and replication. Hepatic pgRNA and cccDNA expression levels indicate viral persistence and replication activity. This
