Ion‐Driven Regulation of Ca2+ Flow by Ti/Zn Composite Activates ERK/MAPK Signaling and Maintains Mitochondrial Homeostasis to Promote Macrophage‐Mediated Bone Regeneration

open access: yesAdvanced Science, EarlyView.
A 3D‐printed interpenetrating Ti/Zn composite enables sustained Zn2+ release to regulate intracellular Ca2+ redistribution, preserve mitochondrial homeostasis, activate ERK/MAPK signaling, and promote M2 macrophage polarization, thereby enhancing osteoimmune‐mediated bone regeneration and peri‐implant osseointegration.

Chinese Trade Competition and Rural Mexican Migration

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT China's accession to the World Trade Organization in 2001 reshaped global trade, reducing U.S. demand for Mexican manufactured goods and weakening Mexico's manufacturing employment. This study estimates how this trade‐induced decline affected migration and employment decisions among rural Mexicans.

Projects for the Regulation of Space Traffic Management

open access: yesTeka Komisji Prawniczej PAN Oddział w Lublinie
The elements of the STM regime are the two dimensions of space traffic (in the scientific-technical and regulatory domains) and the three phases of space traffic: the launch, the on-orbit operations and the return. Examples of traffic regulations include launch safety rules, a specific air-space regime, manned spacecraft safety rules, regulations ...

When the River Runs Low: Heterogeneous Impacts of Transportation Disruptions on Local Grain Basis

open access: yesAgribusiness, EarlyView.
ABSTRACT A substantial share of U.S. soybean and corn exports from the Midwest moves by barge along the Mississippi River system to export terminals in the Louisiana Gulf. Transportation costs between Midwestern grain elevators and export terminals create a wedge between prices at these locations, and shocks to these costs are partially passed on to ...
