Regular operator convergence and nonlinear equations involving numerical ranges

, 1995
Regular operator approximation theory, based on the work of Anselone and Lei (1986), is generalized to the case of strongly accretive operators and applied to nonlinear equations involving the generalized Zarantonello numerical ...

Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.

Quantification of dryland depositional environments across contrasting fluvio‐aeolian and fluvio‐lacustrine transects: An integrated subsurface and outcrop analogue study of the Organ Rock Formation, Utah, USA

Sedimentology, EarlyView.
ABSTRACT The standard subdivision of a distributive fluvial system (DFS) into proximal, medial and distal zones is typically based on the proportion of channel bodies and/or the degree of channel amalgamation, reflecting a downstream fining trend towards a mud‐prone terminal pinch‐out.

Zeros and mapping theorems for perturbations of m-accretive operators in Banach spaces

, 2005
Let X be a real Banach space and T : D(T) ⊂ X → 2X be an m-accretive operator. Let C : D(T) ⊂ X → X be a bounded operator (not necessarily continuous) such that C(T + I)−1 is compact.

Downcurrent variation in submarine channel‐fill architecture from the shelf to upper slope

Sedimentology, EarlyView.
ABSTRACT The transition between the shelf and the upper slope is often considered an area of sediment bypass, where steeper gradients increase flow velocities and maintain particles in suspension. In addition to transferring sediments into deeper basins, upper‐slope areas can also host channelised submarine deposits.

Progesterone does not modulate myofibrillar protein synthesis at rest or following acute resistance exercise in premenopausal females

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty premenopausal females in the early follicular phase (days 1–5) were randomised, double‐blind, to two 400 mg oral doses of micronized progesterone or matched placebo, taken 34 and 10 h before a primed continuous l‐[ring‐13C6]‐phenylalanine infusion beginning at t = −240 min. Bilateral vastus lateralis biopsies were obtained

A Generalization of Lions’ Theorems to Accretive Operator Coefficients for First-Order Operator-Differential Equations with Variable Domains

, 2008
In the present paper three well-known Theorems of correct solvability in [1, p. 129, 138, 142] are generalized to evolution operator-differential equation with time-variable domains of accretive operators and to new class of the mixed problems for odd ...

Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System

Reviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.

Scalar Aesthetics and the Public Politics of Home

The Geographical Journal, Volume 192, Issue 4, December 2026.
ABSTRACT In this article, I demonstrate the value of attending to scalar aesthetics. By scalar aesthetics, I mean the showing, making perceptible or making public of relations between big and small, specific and general, local and global, domestic and international.
