Gaussian Process Regression–Neural Network Hybrid with Optimized Redundant Coordinates: A New Simple Yet Potent Tool for Scientist's Machine Learning Toolbox

open access: yesAdvanced Intelligent Discovery, EarlyView.
A machine learning method, opt‐GPRNN, is presented that combines the advantages of neural networks and kernel regressions. It is based on additive GPR in optimized redundant coordinates and allows building a representation of the target with a small number of terms while avoiding overfitting when the number of terms is larger than optimal.

Persistent Mono‐Oxo Bonding with Protactinium(V) Revealed in Highly Acidic Chloride Solutions

open access: yesAngewandte Chemie, EarlyView.
Protactinium(V) defies expectations. Its elusive mono‐oxo bond was revealed through a combination of extended X‐ray absorption fine structure (EXAFS) and X‐ray absorption near‐edge structure (XANES) analyses, as well as quantum chemical calculations. This bond persists even in 12 M HCl.

Phase‐Change Alloys Enable Localized Reversible Stiffening and Actuation in Steerable Eversion Tip‐Growing Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a tip‐growing eversion robot that uses phase‐changing alloys for reversible stiffening and localized actuation, achieving 43× stiffness modulation, 15× force amplification, and segmental steering. The system enables precise navigation and force delivery in constrained, tortuous pathways.

Boosting the Nucleophilicity of the Diphenylphosphide Anion with Crown Ether Supported Heavy Alkali Metals to Facilitate Highly Efficient Catalytic Alkene Isomerisation

open access: yesAngewandte Chemie, EarlyView.
Here, we report a breakthrough study in catalytic alkene isomerisation using crown ether‐supported alkali metal phosphides in which the activity increases sequentially and significantly as Group One is descended with Cs(18‐crown‐6)PPh2 (1Cs) performing best.

Effect of Red Blood Cell Transfusion on Inflammatory and Angiogenic Pathways in Patients With Sickle Cell Disease

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Sickle cell disease (SCD) is a chronic inflammatory state, characterized by increased plasma values of inflammatory and angiogenic proteins. Although red blood cell (RBC) transfusion is known to have immunomodulatory effects in other conditions, its potential effects on the inflammatory state in SCD remain largely unknown.

Encapsulated Non‐Exchangeable Na+ Ions Determining the Upper Limit of Al Inclusion in FAU—A Multiscale Simulation

open access: yesAngewandte Chemie, EarlyView.
DFT computation, AIMD simulations, machine learning, statistical analysis, and experimental characterization reveal that the upper limit of Al inclusion in FAU zeolite synthesized under hydrothermal conditions is determined by the encapsulated non‐exchangeable Na+ ions.

Characterization of inflammatory pseudotumors in a large animal model of liver cancer

open access: yesAnimal Models and Experimental Medicine, EarlyView.
CT images in arterial and portal venous phases of liver lesions in Oncopig. Abstract Background The development of relevant and robust large animal models of hepatocellular carcinoma is needed to test new therapeutic strategies for this disease. Transgenic approaches hold promise in addressing this complex problem. One such model, the Oncopig, has been
