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

open access: yesSedimentology, 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.

Infinite products of resolvents of accretive operators

open access: yes, 2000
We study the space $\mathcal M_m$ of all $m$-accretive operators on a Banach space $X$ endowed with an appropriate complete metrizable uniformity and the space $\overline{\mathcal M}{}^*_m$ which is the closure in $\mathcal M_m$ of all those operators

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

open access: yesSedimentology, 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.

Abstract Characterizations of Ordered Operator Spaces

open access: yes, 2017
We demonstrate new abstract characterizations for unital and non-unital operator spaces. We characterize unital operator spaces in terms of the cone of accretive operators (operators whose real part is positive).

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

open access: yesSedimentology, 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.

Gravel and sand barrier preservation at geological (Cenozoic) timescales: Insights from the southern Namibia continental shelf

open access: yesSedimentology, EarlyView.
ABSTRACT An apparent disconnect exists between the morphology and behaviour of modern coastal barriers and barrier‐associated sediments preserved in the geological record, reflecting modification and selective preservation over geological timescales.

The Emergence of Peace and Conflict Studies: Comparing Differences in the Creation of Academic Programs With Ties to Social Movements in US Higher Education

open access: yesSociological Forum, EarlyView.
ABSTRACT This article expands the sociological scholarship on the development of academic programs in intellectual fields tied to social movements. After briefly reviewing this literature, which has especially focused on fields like ethnic studies and women's studies, it examines the development of the smaller field of peace and conflict studies.
