Determining The Cost-Effective Methods for Heat Exchanger Maintenance Using Extreme Value Analysis (EVA)

open access: yesPlatform, a Journal of Engineering
This study discusses the application of extreme value analysis (EVA) to evaluate the remaining lifespan of four integral heat exchangers (HEX) at a chemical process plant. Data from plugged tubes and sample tube pit depth inspections, collected using the

Gastrula‐Premarked Posterior Enhancer Primes Posterior Tissue Development Through Cross‐Talk with TGF‐β Signaling Pathway

open access: yesAdvanced Science, EarlyView.
A gastrula‐premarked enhancer within the first intron of Cdx2 governs posterior embryonic development via both regulating Cdx2 expression in cis and coordinating TGF‐β signaling in trans to ensure proper posterior body development. Functional rescue in gastruloids reveals a Cdx2‐independent pathway, highlighting p‐Enh‐eRNA as key epigenetic ...

Activity‐Selectivity Trends in Electrochemical Urea Synthesis: Co‐Reduction of CO2 and Nitrates Over Single‐Site Catalysts

open access: yesAdvanced Science, EarlyView.
In this work, a series of single‐site metal phthalocyanine catalysts (MPcs (M = Zn, Co, Ni, Cu, and Fe)) are screened to learn their activity‐selectivity relationship in the co‐reduction reaction of CO2 and nitrates toward urea formation, which can be significantly promoted by enhanced adsorption of *HOOCNO, reduced adsorptions of *N and *COOH, and ...

A Novel OsMPK6‐OsMADS47‐PPKL1/3 Module Controls Grain Shape and Yield in Rice

open access: yesAdvanced Science, EarlyView.
OsMADS47 is identified as a key regulator governing rice grain morphology. Phosphorylation‐dependent regulation of its activity directs the development of slender versus round grains, modulating both yield and appearance. This mechanism bridges cellular signaling with transcriptional regulation, establishing a molecular framework for grain optimization.
