Diagnosis of Portal Hypertension: Advancing Towards Non‐Invasive Solutions

open access: yesPortal 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 ...

An extinction‐emergency metacollection: Maximising future recovery options for Rhodomyrtus psidioides (Myrtaceae), threatened by Myrtle Rust

open access: yesPLANTS, 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 ...

Cancer rates over age, time, and place: insights from stochastic models of heterogeneous populations [PDF]

open access: yes
Individuals at the same age in the same population differ along numerous risk factors that affect their chances of various causes of death. The frail and susceptible tend to die first.

Understanding the effects of siblings on child mortality: evidence from India [PDF]

open access: yes, 2006
Given the intrinsically sequential nature of child birth, timing of a child’s birth has consequences not only for itself, but also for the older and younger siblings.

Experimental dissection of phenotypic variation for quantitative disease resistance in canola (Brassica napus) – Leptosphaeria maculans interactions

open access: yesPest Management Science, EarlyView.
This graphical abstract illustrates how quantitative resistance to Leptosphaeria maculans in canola is experimentally estimated through multi‐environment replicated trials measuring crown canker severity. Genotype, environment and pathogen sources feed into phenotyping, followed by variance partitioning using mixed models and beta regression to ...

Do spatially targeted weed management strategies increase risk of herbicide resistance evolution?

open access: yesPest 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 ...

Stochastic optimization of heuristic method rule to determine asset allocation to retirement portfolio

open access: yesBusiness: Theory and Practice, 2011
The article examines the problem of determining asset allocation to sustainable retirement portfolio. The article attempts to apply heuristic method – 100 minus age in stocks rule – to determine asset allocation to sustainable retirement portfolio. Using

A comparison of ten principal component methods for forecasting mortality rates [PDF]

open access: yes
Using the age- and sex-specific data of 14 developed countries, we compare the short- to medium-term accuracy of ten principal component methods for forecasting mortality rates and life expectancy. These ten methods include the Lee-Carter method and many

Semi‐mechanistic population PK/PD model to aid clinical understanding of myelodysplastic syndromes following treatment with Venetoclax and Azacitidine

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 448-459, March 2025.
Abstract Myelodysplastic syndromes (MDS) represent a group of bone marrow disorders involving cytopenias, hypercellular bone marrow, and dysplastic hematopoietic progenitors. MDS remains a challenge to treat due to the complex interplay between disease‐induced and treatment‐related cytopenias.

An application of the nonselfadjoint operators theory in the study of stochastic processes

open access: yes, 2004
The theory of operator colligations in Hilbert spaces gives rise to certain models for nonselfadjoint operators, called triangular models. These models generalize the spectral decomposition of selfadjoint operators.
