Geochemistry, Geophysics, Geosystems, 2023 A tectonic window into the upper 2,000 m of oceanic crust generated at the superfast spreading (∼142 mm/yr) southern East Pacific Rise exposes a continuous layered structure of basaltic lavas and sheeted dikes over gabbroic rocks.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Adolescent siblings of children with cancer are at elevated risk for psychosocial problems. Unfortunately, various barriers such as limited family time and resources, conflicting schedules, and psychosocial staffing constraints at cancer centers hinder sibling access to support.

Recent Seismic Studies at the East Pacific Rise 8°20'–10°10'N and Endeavour Segment: Insights into Mid-Ocean Ridge Hydrothermal and Magmatic Processes [PDF]
Oceanography, 2012 As part of the suite of multidisciplinary investigations undertaken by the Ridge 2000 Program, new multichannel seismic studies of crustal structure were conducted at the East Pacific Rise (EPR) 8°20'–10°10'N and Endeavour Segment of the Juan de Fuca ...

Gravitational Potential Energy per Unit Area as a Constraint on Archean Sea Level
Geochemistry, Geophysics, Geosystems, 2018 To constrain the density structure of Archean lithosphere, I assume that gravitational potential energy (GPE) per unit area at Archean spreading centers equals that for continents whose surfaces lay near sea level.

Antigen presentation by B cells enables epitope spreading across an MHC barrier
Nature Communications, 2023 Circumstantial evidence suggests that B cells may instruct T cells to break tolerance. Here, to test this hypothesis, we used a murine model in which a single B cell clone precipitates an autoreactive response resembling systemic lupus erythematosus (SLE)

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Measurements and Models of Heat Flux and Plumes from Hydrothermal Discharges Near the Deep Seafloor [PDF]
Oceanography, 2012 Deep-sea hydrothermal vents are conduits of heat and chemicals from the lithosphere to the hydrosphere. Their plumes rise hundreds of meters from the seafloor into the water column; during their ascent, they entrain ambient water and are subject to cross

Behavioral Modeling of IC Ports Including Temperature Effects [PDF]
, 2002 The development of temperature-dependent macromodels for digital IC ports is addressed. The proposed modeling approach is based on the theory of discrete-time parametric models and allows one to estimate the model parameters from voltage and current ...

Birth of an intraoceanic spreading center
Geology, 2008 The Cocos-Nazca spreading center is one of the few examples of the formation of a spreading center by splitting of oceanic lithosphere. It was created when the Farallon plate, broke up in the early Miocene following the collision of the Pacific-Farallon spreading center with the North American continent. Much of the ancient Farallon plate corresponding
