Harmine Derivatives as Anticancer Agents Endowed With Potent and Selective Antileukemia Activity: Synthesis, Biological Evaluation, Proapoptotic and Genotoxic Activity

open access: yesArchiv der Pharmazie, Volume 359, Issue 2, February 2026.
We identified a novel N9‐substituted harmine analog, compound 6, that selectively suppresses leukemic cell growth, triggers DNA damage, and activates apoptosis while sparing healthy fibroblasts. This discovery highlights N9‐modified β‐carbolines as a powerful new class of selective antileukemic agents, bridging natural product chemistry with next ...

The Effects of Uncertainty on Economic Conditions Across US States: The Role of Climate Risks

open access: yesScottish Journal of Political Economy, Volume 73, Issue 1, February 2026.
ABSTRACT We analyze the impact of uncertainty on the Economic Conditions Index (ECI) of the 50 US states in a panel data set‐up, over the weekly period of the 3rd week of April 1987 to the 4th week of March 2023. Using impulse response functions (IRFs) from a linear local projections (LP) model, we show that uncertainty, as captured by the stochastic ...

Effects of extreme heat events on crop revenues for U.S. corn and soybeans

open access: yesAmerican Journal of Agricultural Economics, Volume 108, Issue 1, Page 176-203, January 2026.
Abstract Extreme weather events have nuanced implications for crop producers. While they can reduce local yields, widespread production losses often drive price increases. This study presents a panel approach that accounts for the price–yield correlation to assess the impact of such events on crop revenues, focusing on U.S. corn and soybeans.

The Dynamics of European Economic Systems Amid the Russia–Ukraine Conflict: A Cybernetics Approach

open access: yesThe American Journal of Economics and Sociology, Volume 85, Issue 1, Page 129-148, January 2026.
ABSTRACT This study analyzes the dynamics of European economic systems in the context of the Russia–Ukraine conflict, employing a cybernetics approach and advanced econometric models. Based on the premise that national economies operate as complex adaptive systems, the study investigates the impact of geopolitical shocks on macroeconomic equilibrium ...

Surface Wave Solutions in 1D and 2D for the Broer–Kaup–Boussinesq–Kupershmidt System

open access: yesStudies in Applied Mathematics, Volume 156, Issue 1, January 2026.
ABSTRACT The Broer–Kaup–Boussinesq–Kupershmidt (BKBK) system is a singular perturbation of the classical shallow water equations which modifies their transport velocity to depend on wave elevation slope. This modification introduces backward diffusion terms proportional to a real parameter κ$\kappa$.

Multisource Heterogeneous Monitoring Data Fusion‐Based Transmission Line Galloping Prediction Method

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
Transmission line galloping poses significant hazards and seriously threatens the security of power systems. Therefore, timely and accurate prediction of line galloping is crucial to prevent and mitigate its damage. Existing galloping prediction methods typically rely on single‐channel optical fiber vibration signals, which suffer from incomplete ...
