Evaluation of a Model of Effective Thermal Conductivity in Soils by Power Averaging Partial Conductivities

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 105-116, February 2026.
ABSTRACT Background Soil thermal conductivity is a key factor for the soil heat balance and is widely used in many fields of soil science. However, it is necessary to measure thermal conductivity of soils that have different porosities and degrees of saturation.

Deep Neural Network With a Smooth Monotonic Output Layer for Dynamic Risk Prediction

open access: yesStatistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT Risk prediction is a key component of survival analysis across various fields, including medicine, public health, economics, engineering, and others. The fundamental concern of risk prediction lies in the joint distribution of risk factors and the time to event.

Nearest Neighbor and Kernel Survival Analysis: Nonasymptotic Error Bounds and Strong Consistency Rates

open access: yes, 2019
We establish the first nonasymptotic error bounds for Kaplan-Meier-based nearest neighbor and kernel survival probability estimators where feature vectors reside in metric spaces.

A Path‐Specific Effect Approach to Mediation Analysis With Time‐Varying Mediators and Time‐to‐Event Outcomes Accounting for Competing Risks

open access: yesStatistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT Not accounting for competing events in survival analysis can lead to biased estimates, as individuals who die from other causes do not have the opportunity to develop the event of interest. Formal definitions and considerations for causal effects in the presence of competing risks have been published, but not for the mediation analysis setting

A Functional Joint Model for Survival and Multivariate Sparse Functional Data in Multi‐Cohort Alzheimer's Disease Study

open access: yesStatistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT We develop an integrative joint model for multivariate sparse functional and survival data to analyze Alzheimer's disease (AD) across multiple studies. To address missing‐by‐design outcomes in multi‐cohort studies, our approach extends the multivariate functional mixed model (MFMM), which integrates longitudinal outcomes to extract shared ...

Test–retest variability of the full‐field stimulus test in patients with retinitis pigmentosa: REPEAT Study Report No. 4

open access: yesActa Ophthalmologica, Volume 104, Issue 1, Page 89-97, February 2026.
Abstract Purpose To evaluate test–retest variability (TRV) of the full‐field stimulus test (FST) in patients with retinitis pigmentosa (RP) and poor best‐corrected visual acuity (BCVA; ≤20/50 Snellen; ≥0.40 logMAR), and to assess the reliability of FST as a clinical endpoint in future RP trials.

Testing a General Theory for Optimal Flowering Time in Deciduous Perennial Plants as a Function of Growing Season Length

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
Climate change affects both the start and duration of growing seasons, creating complex effects on optimal flowering timing that go beyond simple responses to earlier springs. Using optimal energy allocation theory, we found a nonlinear relationship between growing season length and optimal flowering time which was supported by two experiments with ...

ZnO‐Hydroxyapatite‐Coated Ti‐6Al‐4V With Curcumin and Ginger Extract for Load‐Bearing Implants

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT There is a rising trend in the number of clinical cases related to bone implantation and bone cancer across the globe due to longer life expectancy, accidents, and sports‐related injuries. In this study, we have used curcumin and ginger extract as alternate osseointegrating agents with in vitro osteosarcoma inhibition potential for load ...
