Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

open access: yesGeological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Population dynamics of Townsend's big‐eared bats: effect of age and drought on survival

open access: yesThe Journal of Wildlife Management, EarlyView.
We estimated age‐specific yearly survival of female Townsend's big‐eared bats in Inyo and Mono Counties, California. We found that both juvenile and adult survival were negatively impacted by drought, and that detection probability was lower for hand‐recapture than for bats detected via pass‐through antenna arrays.

Formation processes of the 1909 Tarumai and the 1944 Usu lava domesin Hokkaido, Japan

open access: yesAnnals of Geophysics, 2004
The formation of the two particular lava domes in Hokkaido, Japan is described and interpreted mainly from geophysical viewpoints. The 1909 eruption of Tarumai volcano was not violent but produced a lava dome over four days.

Geodiversity and Its Implication for Geoconservation of the Youngest Eruptive Sites of Western Samoa

open access: yesProceedings, 2022
The last volcanic eruption in Western Samoa, which occurred between 1905 and 1911, produced a complex scoria and lava spatter cone and an extensive lava field that destroyed Sale’aula village, near the Pacific coast.

Unrecorded liverwort species from Korean flora IV: new data on Riccia L. (Marchantiophyta) from Jeju UNESCO World Natural Heritage

open access: yesJournal of Asia-Pacific Biodiversity, 2020
While conducting a floristic study of Korean bryophytes, we discovered two unrecorded species collected from dirt roads near Manjanggul Lava Tube (Jeju UNESCO World Natural Heritage) in Korea. Riccia beyrichiana Hampe and Riccia bifurca Hoffm.

Determination of eruption temperature of Io's lavas using lava tube skylights [PDF]

open access: yesIcarus, 2016
Determining the eruption temperature of Io's dominant silicate lavas would constrain Io's present interior state and composition. We have examined how eruption temperature can be estimated at lava tube skylights through synthesis of thermal emission from the incandescent lava flowing within the lava tube.

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review

open access: yesSystems Engineering, EarlyView.
ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to
