Drivers of Greenhouse Gas Emissions in Tropical Riverine Systems Across a Gradient of Human Impact
International Review of Hydrobiology, Volume 111, Issue 1, June 2026.ABSTRACT Tropical lotic ecosystems are important sources of greenhouse gas emissions, yet the magnitude and variability of such emissions remain poorly constrained. Here, we quantified spatial and short‐term temporal variability of carbon dioxide (CO2) and methane (CH4) fluxes across tropical riverine systems spanning a gradient of human impact, while ...

People and Nature, Volume 8, Issue 6, Page 1852-1868, June 2026.Abstract The societal and biophysical permeability across human‐demarcated jurisdictions within watersheds necessitates collaboration among administrative regions. The effectiveness of such collaboration is partly determined by the degree to which institutional arrangements align with underlying social and ecological interdependencies, a concept ...

Water Resources Research, Volume 62, Issue 6, June 2026.Abstract River corridors are essential to life, but have been subjected to centuries of alteration, disconnection, and simplification. Process‐based river restoration has increased in recent years, with the goals of reversing degradation and reestablishing natural processes. Our objectives are twofold: (a) qualify the historic, ecologic, and geomorphic

Water Resources Research, Volume 62, Issue 6, June 2026.Abstract Snowmelt is a dominant hydrologic process in mountainous watersheds and western river systems, yet automatic logging of snowpack properties such as depth, density, and internal energy fluxes, especially during melt, is not done at many Rocky Mountain surface flux sites.

Superposition of Markov Renewal Processes.
, 1981 The superposition of Markov renewal processes is investigated to derive the probability that such a pooled process is in a given state at a given time or that such a process will go next to one state given that it is now in another.

Psychology and Psychotherapy: Theory, Research and Practice, Volume 99, Issue 2, Page 301-323, June 2026.Abstract Purpose Cognitive‐behavioural therapy for psychosis (CBTp) achieves small to modest effect sizes, which invites the question, ‘What clinical modifications might improve outcomes?’ This paper proposes an integration of CBTp with a neuropsychoanalytic approach that in clinical practice might extend the gains achieved by CBTp alone.

Construction and Stationary Distribution of the Fleming-Viot Process with Viability Selection [PDF]
This paper provides an explicit construction of the Fleming-Viot process with viability selection in a Bayesian nonparametric framework, and derives its stationary distribution. The measure-valued diffusion is obtained as the infinite population limit of

, 2013 We consider the geometric Markov renewal processes (GMRP) as a model for a security market. Normal deviations of the geometric Markov renewal processes for ergodic averaging and double averaging schemes are derived.

Loop-free Markov chains as determinantal point processes [PDF]
, 2008 We show that any loop-free Markov chain on a discrete space can be viewed as a determinantal point process. As an application, we prove central limit theorems for the number of particles in a window for renewal processes and Markov renewal processes with

Superposed renewal processes: a Markov renewal approach
, 1995 Lam and Lehoczky (1991) have recently given a number of extensions of classical renewal theorems to superpositions of p independent renewal processes. In this article we want to advertise an approach that more explicitly uses a Markov renewal theoretic ...
