Macroeconomic Effects of Public Investment in EMDEs: Nonlinear Effects of the Business Cycle, Fiscal Space, Capital Stock and Efficiency

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT The paper examines the macroeconomic effects of public investment in emerging market and developing economies (EMDEs). To this end the analysis develops a new measure of public investment shocks based on cyclically adjusted government investment.

Endothelial thrombomodulin—Its role in trauma‐induced coagulopathy

Transfusion, EarlyView.
Abstract Background Trauma‐induced coagulopathy (TIC) describes a complex set of coagulation changes affecting severely injured patients. The thrombomodulin‐protein C axis is central to the evolution of TIC. Soluble thrombomodulin (sTM) levels are elevated after injury and predict poor clinical outcomes.

Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

MedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,

In Situ Detection of Opal‐A in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract We report the in situ detection of amorphous hydrated silica in the Bills Bay abrasion patch, located in the eastern portion of the Margin Unit between the rim of Jezero crater and the western delta. Here, hydrated silica co‐occurs with olivine, Fe‐Mg carbonates, secondary Fe‐Mg silicates, and hydrated Mg‐sulfate as determined by UV Raman ...

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

Journal of Anatomy, Volume 248, Issue 5, Page 784-805, May 2026.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

Determination of geopotential difference by hydrogen masers based on precise point positioning time-frequency transfer

, 2023
According to the general relativity theory, the geopotential difference can be determined by gravity frequency shift between two clocks. Here we report on the experiments to determine the geopotential difference between two remote sites by hydrogen ...

Mass Spectrometry Imaging Combined With Single‐Cell Transcriptional Profiling Reveals the Multidimensional Spatial Distributions and Biosynthetic Pathways of Medicinal Components in Andrographis paniculata

Plant Biotechnology Journal, Volume 24, Issue 5, Page 2876-2890, May 2026.
ABSTRACT The synthesis and accumulation of active ingredients in medicinal plants are distributed in specific organs, tissues, and cell types, which are important for the exploitation of medicinal plants. However, the fine distribution of active ingredients is difficult to know. Here, the system of mass spectrometry imaging (MSI) integrated with single‐

Internet, Inequality, and Regime Stability

Scottish Journal of Political Economy, Volume 73, Issue 2, May 2026.
ABSTRACT This study examines the link between income inequality and political instability, focusing on the moderating role of Internet penetration. Using data from over 120 countries (1996–2020), we find a conditional relationship: in low‐Internet countries, higher inequality associates with lower instability, likely due to limited political awareness ...
