The Dunhuang Block, located in the eastern margin of the Tarim Craton, possesses a wealth of information about the geological evolution of the Tarim Craton. In this study, we conducted detailed petrological,geochemical and geochronological investigations on garnet-bearing amphibolites as well as granites in the Dunhuang Block, which record important metamorphic and magmatic events that are poorly constrained. Based on field occurrence, geochronological and geochemical characteristics, the garnetbearing amphibolites can be divided into two groups. Group I garnet-bearing amphibolite displays typical features of island arc basalts, which may formed at ～1.83 Ga in a collisional setting during the assembly of the Columbia supercontinent, whereas group II has geochemical characteristics of ocean island basalt which may formed at ～1.61 Ga in an ocean island setting. The ca. 1.83 Ga amphibolite has positive εHf(t)values(+4.4 to +8.9), with T DM1 model ages of 2.02–1.83 Ga, indicating an important addition of juvenile mantle-derived materials during the formation of its protolith. The ca. 1.61 Ga amphibolite has εHf(t)values ranging from-0.6 to +5.6 and corresponding T DM1 model ages varying from 2.03 Ga to 1.84 Ga,which suggest that juvenile mantle-derived materials were dominantly contributed to the formation of its protolith but were later contaminated by crustal materials. The U–Pb ages obtained from the rims of the zircon grains in amphibolites and granites recorded a tectonothermal event at ca. 400 Ma, which is coeval with the widespread magmatism in the Beishan orogen. We thus propose that these two groups of garnetbearing amphibolites were possibly not related to each other during Paleoproterozoic time, and a late Paleozoic orogenic event brought them together during which both of them underwent metamorphism.

Studying molecular recognition in aqueous environments is crucial for understanding biological processes. Herein, we present a series of N-doped endo-functionalized anthracene-based cavities by introducing inward-directed pyridine units. The subtle modifications can significantly affect the binding properties of these receptors, which is similar to the mutations in biological systems. Combining theoretical calculations and molecular recognition experiments demonstrated that these “mutations” have an impact on the hydrophobicity and charge distribution of the hosts, consequently significantly influencing molecular *** is crucial for understanding the intricate mechanisms of molecular-level interactions in biological receptors.

Establishing the relationship between vibrotactile parameters and perceived intensity（PI） is of great significance in the regulation of desired sensations, which contribute to haptic interfaces in practical applications. Coin eccentric rotating mass（ERM） motors are routinely utilized due to their lightweight design and efficient ability to evoke strong tactile sensations. By adjusting input voltages, ERMs can yield different stimuli, but the effects of their physical properties on PI remain ***, we developed the physical model of the ERM-skin system and optimized the parameters affecting PI. Moreover, the relationship between stimulus and perception was derived based on Fechner?s law. Three experiments were conducted on fifteen subjects（ten males and five females, aged 24.40 ± 2.87 years） to identify the vibration parameters and corresponding PI to verify the proposed PI model. ERMs in this study were attached to phantom skin/forearm with slim adhesive tape to minimize the interference. Experiment 1 performed vibration calibration with ERM attached to the skin phantom to simulate the actual configuration. Then, the relative and absolute PI of subjects on specific stimuli were acquired in Experiments 2 and *** fitting reliability of the proposed PI model was evaluated on fifteen subjects with R2of 0.73 ± 0.07 and root mean squared error（RMSE） of 1.35 ± 0.28. Overall, the proposed PI model established the quantitative relationship between stimulus parameters（vibration parameters and physical parameters） and subjective PI, which provided theoretical support for ERM optimization and vibrotactile modulation.
