Composite Pentamode Metamaterials for Enhanced Wave Manipulation by Asymmetric Surface Structure

Small Structures, EarlyView.
The asymmetric pentamode surface structure can reduce the scattering from 26.3 dB to 0.96 dB and multiply the frequency range of wave manipulation. This approach results in a 95% improvement in compressive strength compared to pentamode structures with the same acoustic performance, enabling wider deepwater applications.

Occurrence, ecology and management of Fascioloides magna in Bavaria, southern Germany

Wildlife Biology, EarlyView.
In 2015, red deer infected with American liver fluke were discovered in the Veldenstein Forest area for the first time. This was the first detection of the fluke in a wild deer population in Bavaria. The aim of the study was to determine the American liver fluke prevalence rates in red deer, roe deer and wild boar in the Veldenstein Forest, as well as ...

Cs4Ca[Si8O19]: a new mixed tetrahedral–octahedral oxosilicate, its topological features and comparison with other interrupted framework silicates

Acta Crystallographica Section B, EarlyView.
The crystal structure of the mixed tetrahedral–octahedral framework silicate Cs4Ca[Si8O19] has been solved. A topological analysis of the present compound and other interrupted framework silicates is presented.Single crystals of a previously unknown caesium calcium silicate with the composition Ca4Ca[Si8O19] have been obtained during a systematic study

Telomere Position Effect‐Over Long Distances Acts as a Genome‐Wide Epigenetic Regulator Through a Common Alu Element

Aging Cell, EarlyView.
Proposed TPE‐OLD model. TPE‐OLD genes are defined by a progressive modulation of gene expression following telomere attrition. In our study, focusing on the molecular mechanism of TPE‐OLD, we found that the TPE‐OLD loop requires a cis‐signature corresponding to a newly evolved Alu repeats (AluY). The Alu repeat can be either in an intergenic region, as

Senescent Macrophages Promote Age‐Related Revascularization Impairment by Increasing Antiangiogenic VEGF‐A165B Expression

Aging Cell, EarlyView.
The underlying mechanisms of age‐related revascularization impairment are not clear. Our research firstly identified that macrophages were more senescent in the ischemic skeletal muscle of old mice and senescent macrophages could inhibit revascularization.

Aerobic Exercise Restores Hippocampal Neurogenesis and Cognitive Function by Decreasing Microglia Inflammasome Formation Through Irisin/NLRP3 Pathway

Aging Cell, EarlyView.
Exercise improved PD pathology and memory by reducing microglial inflammation, apoptosis, and the formation of the NLRP3 inflammasome via irisin signaling. Irisin administration partially replicated the beneficial effects of exercise on PD pathology.

Allergic Reactivity and Memory Occur Independently of Sequential Switching Through IgG1

Allergy, EarlyView.
Sequential switching through IgG1 is not required to produce IgE with sufficient allergen‐binding affinity to cause anaphylaxis against food allergens. Sequential switching through IgG1 does not confer a competitive advantage to become an IgE‐expressing cell.
