Cross Taxon Congruence Between Lichens and Vascular Plants in a Riparian Ecosystem

open access: yesDiversity, 2019
Despite that congruence across taxa has been proved as an effective tool to provide insights into the processes structuring the spatial distribution of taxonomic groups and is useful for conservation purposes, only a few studies on cross-taxon congruence

Synergistic Effect of Gradient Conductivity and Gradient Microstructures Enabled Ultrasensitive and Ultrabroad Linear Flexible Tactile Sensors

open access: yesAdvanced Science, EarlyView.
A design of double gradient effect is proposed to resolve the contradictory optimization on sensitivity and linearity of piezoresistive tactile sensors. The ultrawide linearity is realized by the sequential trigger of pressure‐induced gradient conductivity‐enabled linear current owing to the gradient microstructures.

Enhanced Mechanical Properties Via Boron‐Induced Multi‐Mechanism Strengthening in (NbTaTi1.5V)100‐xBx Refractory High Entropy Alloys

open access: yesAdvanced Science, EarlyView.
A trace amount of boron is introduced into NbTaTi1.5V RHEA, forming a finegrained BCC+TiO+TiB microstructure. The TiB phase generates numerous dislocations, strengthening the alloy. The alloy exhibits 3610 MPa compressive fracture strength and 1060 HV microhardness, while retaining 14.8% fracture strain.

Variation in parrot jaw musculature

open access: yesThe Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Long‐term outcomes of microsurgical interdental papilla reconstruction: 13‐year and 18‐year case follow‐ups

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Loss of the interdental papilla compromises esthetics, speech, and hygiene, significantly affecting quality of life and psychological well‐being. Reconstruction has long been considered unpredictable, particularly in Cairo RT3 cases with advanced interproximal bone loss.
