Finite dimensional Markovian realizations for stochastic volatility forward rate models [PDF]
We consider forward rate rate models of HJM type, as well as more general infinite dimensional SDEs, where the volatility/diffusion term is stochastic in the sense of being driven by a separate hidden Markov process.

Pediatric Discovery, EarlyView.MSC‐Exo derived from human umbilical cord (HucMSC‐Exo) downregulates INHBA expression, consequently modulating the PI3K/AKT signaling cascade. This regulation attenuates renal fibroblast activation and extracellular matrix deposition, thereby exerting a renoprotective effect against fibrosis.

Diagnosis of Portal Hypertension: Advancing Towards Non‐Invasive Solutions
Portal Hypertension &Cirrhosis, EarlyView.This review systematically summarizes a full spectrum of non‐invasive diagnostic approaches for portal hypertension (PH), including imaging modalities, elastography, serum biomarkers, composite scoring systems and endoscopic ultrasound‐guided portal pressure gradient (EUS‐PPG), and analyzes their performance across different liver disease etiologies ...

PLANTS, PEOPLE, PLANET, EarlyView.A challenge for wild plant conservation is the rising incidence of plant pathogens that are difficult to interdict, contain and manage. Invasive, fast‐moving, broad‐spectrum pathogens impose societal costs through losses of intrinsically valuable wild biodiversity, ecosystem function, current and potential genetic and biological assets, culturally ...

PLANTS, PEOPLE, PLANET, EarlyView.Invasive weeds pose a global challenge to sustainable agriculture, threatening productivity while increasing the costs and uncertainty of crop management. Using 6 years of experimental evidence, we developed and evaluated three 10‐year action plans for controlling Amaranthus palmeri in maize crops in Aragón, Spain, accounting for biological and control‐

Identification and Estimation of Stochastic Bargaining Models, Third Version [PDF]
Stochastic sequential bargaining models (Merlo and Wilson (1995, 1998)) have found wide applications in different fields including political economy and macroeconomics due to their flexibility in explaining delays in reaching an agreement.

Do spatially targeted weed management strategies increase risk of herbicide resistance evolution?
Pest Management Science, EarlyView.Spray‐buffers reduce the effect of detection inaccuracies in spot spraying. We found a trade‐off between short‐term weed population control efficacy and long‐term prevention of herbicide resistance evolution. Abstract Background Spatially targeted spraying is an alternative to broadcast herbicide application that reduces herbicide use by restricting ...

Calibrating affine stochastic mortality models using term assurance premiums
In this paper, we focus on the calibration of affine stochastic mortality models using term assurance premiums. We view term assurance contracts as a "swap" in which policyholders exchange cash flows (premiums vs. benefits) with an insurer analogous to a

Automatic insect identification, counting, and monitoring techniques: a review
Pest Management Science, EarlyView.Automated insect monitoring increasingly integrates optical, acoustic, infrared, radar, electrostatic, and biosensing technologies with artificial intelligence. No single approach is universally optimal; reliable deployment depends on task‐specific validation, representative datasets, robustness under field conditions, energy autonomy, connectivity ...
