Impact of Climate Change on the Potential Distribution of Macaúba (Acrocomia aculeata, Acrocomia totai, Acrocomia intumescens) in Brazil

open access: yesGCB Bioenergy, Volume 18, Issue 8, August 2026.
Climate change is projected to drive contrasting responses among Brazilian macaúba palms, ranging from relative stability and expansion to severe suitability loss. Ensemble ecological distribution models identified Acrocomia intumescens as highly vulnerable, while A.

Firm‐Level Political Risk and Earnings Manipulation

open access: yesJournal of Business Finance &Accounting, Volume 53, Issue 4, Page 1382-1408, August 2026.
ABSTRACT Using recently developed proxies for firm‐level political risk and earnings manipulation, we test the limited attention theory. Contrary to Hirshleifer and Teoh's core prediction that investor attention is associated with less managerial manipulation, we find that firm‐level political risk, serving as a proxy for investor attention, is ...

The Debt‐Equity Spread

open access: yesThe Journal of Finance, Volume 81, Issue 4, Page 2005-2062, August 2026.
ABSTRACT We propose a measure of the valuation gap between debt and equity—debt‐equity spread (DES)—based on the difference between actual and equity‐implied credit spreads. DES predicts cross‐sectional stock and bond returns in opposite directions.

Direct δ‐Lactone Synthesis From Free Alcohols via Photoinduced δ‐C(sp3)–H Carbonylation in Flow

open access: yesAngewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Herein, we have developed a photo‐flow platform for the δ‐C(sp3)─H carbonylative lactonization of free alcohols with carbon monoxide. The transformation integrates alkoxyl radical generation, selective 1,5‐HAT, CO incorporation, and radical–polar crossover to enable direct access to δ‐lactones from simple alcohol precursors.

Temporal Evolution and Stationary Point Mechanisms of Pelvic Characteristic Angles Throughout the Sit‐to‐Stand Cycle

open access: yesOrthopaedic Surgery, Volume 18, Issue 8, Page 1688-1699, August 2026.
Dynamic motion‐capture and musculoskeletal simulation of stand‐to‐sit reveal nonlinear pelvic kinematics in healthy subjects. Pelvic tilt and sacral slope show synchronized mid‐cycle turning points, strongly linked to center‐of‐gravity transitions. These dynamic features, absent in static radiographs, may refine functional acetabular safe zones to ...

Investigation of Substrate Specificity in 5‐Keto‐4‐Deoxy‐Glucarate Dehydratase and 2‐Keto‐3‐Deoxy‐L‐Arabinonate Dehydratase

open access: yesChemBioChem, Volume 27, Issue 14, 29 July 2026.
5‐Keto‐4‐deoxy glucarate dehydratase and 2‐keto‐3‐deoxy‐L‐arabinonate dehydratase share many similarities like structure, reaction mechanism, and their generated product, but exhibit very high substrate specificity. Here, we explore the evolutionary development of this specificity in the context of the enzyme superfamily and attempt to find promiscuous
