End-to-end simulation of high-contrast imaging systems: methods and results for the PICTURE mission family [PDF]

, 2015
We describe a set of numerical approaches to modeling the performance of spaceflight high-contrast imaging payloads. Mission design for high-contrast imaging requires numerical wavefront error propagation to ensure accurate component specifications.

Limno‐STOICH: A comprehensive database linking the elemental stoichiometry of organisms with inland aquatic habitats

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract All organisms contain carbon, nitrogen, and phosphorus in widely ranging amounts and proportions. Integrating existing datasets enables quantification of this variation at global scales. Such efforts could leverage ecological stoichiometry theory, the study of elemental supply and imbalances in ecological interactions, to connect ecological ...

Examining the Affordances of Engineering and Curricular Supports for Learning Among Emerging Bilingual Elementary Afterschool Students

Science Education, Volume 110, Issue 2, Page 357-378, March 2026.
ABSTRACT Engineering design provides students with unique opportunities to engage with disciplinary knowledge and practices by engaging with technologies and each other through the design process. In this paper, we identify how the co‐construction of an engineering afterschool club culture supported students’ engagement in epistemic practices of ...

Anticancer Molecular Mechanisms of Phytosterols: An Updated Review on Clinical Trials

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
Phytosterols, a form of naturally occurring substance structurally related to cholesterol, have been getting considerable interest due to their possible anticancer properties. Phytosterols induce apoptosis, block the cell cycle, and abrogate the invasion and metastasis of cancer cells, offering a multi‐manifestation treatment of cancer.

Uncertainties in Early Stage Capital Cost Estimation of Process Design – A case study on biorefinery design

Frontiers in Energy Research, 2015
Capital investment, next to the product demand, sales and production costs, is one of the key metrics commonly used for project evaluation and feasibility assessment. Estimating the investment costs of a new product/process alternative during early stage

Color Gradients in Early-Type Galaxies in Clusters at the Redshift from 0.37 to 0.56

, 2000
Color gradients in elliptical galaxies in distant clusters ($z=0.37-0.56$) are examined by using the archival deep imaging data of Wide Field Planetary Camera 2 (WFPC2) on-board the Hubble Space Telescope (HST). Obtained color gradients are compared with

A multi‐scale assessment of interior Douglas‐fir tree mortality for hazard and risk assessments

Ecosphere, Volume 17, Issue 1, January 2026.
Abstract Land managers use hazard (susceptibility) and risk rating systems to guide the application of forest management treatments that aim to reduce future damages to forests. Rating systems are typically designed for individual damage agents, but tree mortality often results from multiple agents without a clear proximate cause.

»Za slobodu nas Krist oslobodi« (Gal 5,1) – Poimanje slobode u Poslanici Galaćanima (II.: Sloboda kao sloboda od Zakona)

Nova Prisutnost, 2020
Budući da je vjera, a time i sloboda Galaćana ugrožena pokušajem vraćanja pod Mojsijev zakon, oslanjajući se na biblijsko pripovijedanje o Abrahamu, Pavao progovara o slobodi kao slobodi od Mojsijeva zakona.
