Sapwood and heartwood are not isolated compartments: Consequences for isotope ecohydrology
Ecohydrology, Volume 15, Issue 8, December 2022., 2022 Abstract In most tree species, xylem consists of two different functional parts: sapwood and heartwood. While sapwood, as the flowpath for sap, has received more attention in isotope studies assessing water sources accessed by trees (e.g. soil water from different depths, groundwater, stream water or a mixture of these), much remains unknown about ...

CRUST 5.1: A global crustal model at 5° × 5°
, 1998 We present a new global model for the Earth's crust based on seismic refraction data published in the period 1948-1995 and a detailed compilation of ice and sediment thickness.

Ecology, Volume 103, Issue 12, December 2022., 2022 Abstract The outcomes of species interactions can vary greatly in time and space with the outcomes of some interactions determined by priority effects. On coral reefs, benthic algae rapidly colonize disturbed substrate. In the absence of top‐down control from herbivorous fishes, these algae can inhibit the recruitment of reef‐building corals, leading ...

A strange star model for GRO J1744-28 [PDF]
arXiv, 1998 A model is suggested for the bursting x-ray pulsar, GRO J1744-28, where the compact object of the pulsar is proposed to be a strange matter star with crusts. It is suggested that two envelope crusts shield the two polar caps of an accreting strange stars owing to strong polar-cap magnetic fields.

Angewandte Chemie International Edition, Accepted Article.An organometallic Al(III)K(I) catalyst shows exceptional control in the epoxide/anhydride ROCOP producing high molecular weight polyesters (Mn ~ 100 kg·mol‐1). The catalysis is highly effective using cyclohexene oxide, cyclopentane oxide, substituted cyclohexene oxide, and butylene oxide, each combined with phthalic anhydride.

Role of magnetic fields on the outer crust in a magnetar [PDF]
arXivWe explore the properties of 4110 nuclides from Z = 5 to Z = 82 with the Sky3D code and the composition of the outer crust in the magnetars under extreme magnetic fields. The effects of the variation of the nuclear masses due to the magnetic fields on the outer crust are comprehensively studied.

Crust cooling curves of accretion-heated neutron stars [PDF]
arXiv, 2004 We discuss the recent efforts to use a sub-class of neutron-star X-ray transients (the quasi-persistent transients) to probe the properties of neutron-star crusts and cores. Quasi-persistent X-ray transients experience accretion episodes lasting years to decades, instead of the usual weeks to months of ordinary, short-duration transients.
