title: A new Jehol enantiornithine bird with three-dimensional preservation and ovarian follicles

description: We report a new enantiornithine bird, <i>Linyiornis amoena</i> gen. et sp. nov., from the Lower Cretaceous Jiufotang Formation in northeastern China. Traces of ovarian follicles indicate that the specimen represents a female individual. The nearly three-dimensional preservation of the new specimen reveals morphological details rarely visible in other Early Cretaceous enantiornithines, allowing more detailed comparison with Late Cretaceous enantiornithines. Differences in the preserved morphology of the right and left coracoids suggest that the appearance of some features is strongly affected by preservation, indicating that the distribution of these features in compressed specimens may need to be reevaluated. Like Late Cretaceous enantiornithine specimens, the holotype of <i>Linyiornis amoena</i> preserves a hypertrophied pit for muscle attachment on the bicipital crest but clearly did not preserve a fossa for the capital ligament, present in Late Cretaceous taxa; we discuss the functional morphology and implications of these features in <i>Linyiornis amoena</i>. http://zoobank.org/urn:lsid:zoobank.org:pub:EFFD4348-7376-4201-A948-CEC686E2E0DC SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP Citation for this article: Wang, Y., M.

title: Reducing the risk of rear-end collisions with infrastructure-to-vehicle (I2V) integration of variable speed limit control and adaptive cruise control system

description: <b>Objective</b>: Adaptive cruise control (ACC) has been investigated recently to explore ways to increase traffic capacity, stabilize traffic flow, and improve traffic safety. However, researchers seldom have studied the integration of ACC and roadside control methods such as the variable speed limit (VSL) to improve safety. The primary objective of this study was to develop an infrastructure-to-vehicle (I2V) integrated system that incorporated both ACC and VSL to reduce rear-end collision risks on freeways. <b>Methods</b>: The intelligent driver model was firstly modified to simulate ACC behavior and then the VSL strategy used in this article was introduced. Next, the I2V system was proposed to integrate the 2 advanced techniques, ACC and VSL. Four scenarios of no control, VSL only, ACC only, and the I2V system were tested in simulation experiments. Time exposed time to collision (TET) and time integrated time to collision (TIT), 2 surrogate safety measures derived from time to collision (TTC), were used to evaluate safety issues associated with rear-end collisions. The total travel times of each scenario were also compared. <b>Results</b>: The simulation results indicated that both the VSL-only and ACC-only methods had a positive impact on reducing the TET and TIT values (reduced by 53.0 and 58.6% and 59.0 and 65.3%, respectively). The I2V system combined the advantages of both ACC and VSL to achieve the most safety benefits (reduced by 71.5 and 77.3%, respectively). Sensitivity analysis of the TTC threshold also showed that the I2V system obtained the largest safety benefits with all of the TTC threshold values. The impact of different market penetration rates of ACC vehicles in I2V system indicated that safety benefits increase with an increase in ACC proportions. <b>Conclusions</b>: Compared to VSL-only and ACC-only scenarios, this integrated I2V system is more effective in reducing rear-end collision risks. The findings of this study provide useful information for traffic agencies to implement novel techniques to improve safety on freeways.

title: D-repeat in the <i>XIST</i> gene is required for X chromosome inactivation

description: <i>XIST</i> is a long non-coding RNA, which expressed exclusively from the inactive X chromosome. Although it has been revealed that the A-repeat contributes to the X chromosome inactivation (X-inactivation), the role of the longest D-repeat has not yet been investigated. Here, a sgRNA directed CRISPR/Cas9 system which have multiple target sites within repeat D of <i>XIST</i>, were used to generate D-repeat deletion and studied its roles on X-inactivation. The results showed that the deletion of D-repeat caused a significantly decreased expression of <i>XIST</i>, and up regulated expression of X-linked genes, suggesting that the D-repeat may play an important role in the regulation of <i>XIST</i> expression and silencing of the X-linked genes, which could provide a new idea in the molecular mechanisms of X-inactivation.

title: High-resolution mapping of H4K16 and H3K23 acetylation reveals conserved and unique distribution patterns in <i>Arabidopsis</i> and rice

description: Histone acetylation and deacetylation are key epigenetic gene regulatory mechanisms that play critical roles in eukaryotes. Acetylation of histone 4 lysine 16 (H4K16ac) is implicated in many cellular processes. However, its biological function and relationship with transcription are largely unexplored in plants. We generated first genome-wide high-resolution maps of H4K16ac in <i>Arabidopsis thaliana</i> and <i>Oryza sativa</i>. We showed that H4K16ac is preferentially enriched around the transcription start sites and positively correlates with gene expression levels. Co-existence of H4K16ac and H3K23ac is correlated with high gene expression levels, suggesting a potentially combinatorial effect of H4K16ac and H3K23ac histone 3 lysine 23 acetylation on gene expression. Our data further revealed that while genes enriched with both H4K16ac and H3K23ac are ubiquitously expressed, genes enriched with only H4K16ac or H3K23ac showed significantly distinct expression patterns in association with particular developmental stages. Unexpectedly, and unlike in <i>Arabidopsis</i>, there are significant levels of both H4K16ac and H3K23ac in the lowly expressed genes in rice. Furthermore, we found that H4K16ac-enriched genes are associated with different biological processes in <i>Arabidopsis</i> and rice, suggesting a potentially species-specific role of H4K16ac in plants. Together, our genome-wide profiling reveals the conserved and unique distribution patterns of H4K16ac and H3K23ac in <i>Arabidopsis</i> and rice and provides a foundation for further understanding their function in plants.

title: Structural geometry and kinematics of the Ailao Shan shear zone: insights from integrated structural, microstructural, and fabric studies of the Yao Shan complex, Yunnan, Southwest China

description: The Yao Shan complex, a massif near the southern segment of the Ailao Shan–Red River (ASRR) shear zone, bears important information on the structural framework of the massif and the kinematics of ductile shearing along the ASRR shear zone. In this contribution, structural, microstructural, quartz c-axis fabric, magnetic fabric, and geochronologic data are used to determine the structural framework of the Yao Shan massif and its tectonic implications for the ASRR shear zone. The Yao Shan complex is characterized by an overall linear A-type antiform that contains a core of high-grade metamorphic rocks with Palaeoproterozoic to Mesozoic protoliths and a mantle of Permo-Triassic low-grade rocks. Both the high-grade metamorphic core and low-grade Permo-Triassic rocks have experienced progressive ductile shearing. Anisotropy of magnetic susceptibility (AMS) results from 17 samples collected along the Xinjie–Pingbian section across the complex show that magnetic lineation (<i>K<sub>max</sub></i>) and foliation (<i>K<sub>max</sub></i>–<i>K<sub>int</sub></i>) are generally subparallel to the corresponding structural elements in the sheared rocks. The shape parameter E values of the magnetic ellipsoids are indicative of dominantly oblate and plane strain, but vary with protolith type and degree of strain among the various rock types. In agreement with the field and microstructural observations, the corrected degree of anisotropy (Pj) values reflect high shear strain in the core rocks and relatively low shear strain in the low-grade strata. A kinematic analysis based on structural and magnetic fabric data shows that both left- and right-lateral shear occurred during the deformation of the Yao Shan complex. Therefore, instead of being an element of the ASRR shear zone, the Yao Shan complex constitutes a crustal-scale inharmonic A-type fold with a fold axis parallel to the stretching lineation. Geochronologic data reveal that the folding occurred coevally with ductile shearing of the middle to lower crust between ca. 30 and 21 Ma.

title: Zircon ages and Hf isotopic compositions of Permian and Triassic A-type granites from central Inner Mongolia and their significance for late Palaeozoic and early Mesozoic evolution of the Central Asian Orogenic Belt

description: This work presents zircon ages and Hf-in-zircon isotopic data for Permian and Triassic A-type granitoids and reviews the evolution of central Inner Mongolia, China, during the early Permian and Late Triassic. SHRIMP U–Pb dating of zircons of peralkaline granites yielded <sup>206</sup>Pb/<sup>238</sup>U ages of 294 ± 4 Ma and 293 ± 9 Ma that reflect the time of Permian magmatism. Zircon ages were also obtained for Late Triassic granites (226 ± 4 Ma, 224 ± 4 Ma). Our results, in combination with published zircon ages and geochemical data, document distinct magmatic episodes in central Inner Mongolia. The Permian peralkaline granites show typical geochemical features of A-type granites, which also have highly positive zircon <i>ε</i><sub>Hf(<i>t</i>)</sub> values (+4.9 – +17.1), indicating a significant contribution of an isotopically depleted source, likely formed from mantle-derived magmas. Late Triassic A-type granitoids, however, in central Inner Mongolia show large variations and mostly positive in zircon <i>ε</i><sub>Hf(<i>t</i>)</sub> values (−1.3 – +13.5), suggesting derivation from a mixture of crust and mantle or metasomatized lithospheric mantle with crustal contamination. The geochemical characteristics of the Permian peralkaline granites and Late Triassic A-type granitoids are consistent with a post-collisional setting and were likely related to asthenosphere upwelling during the evolution of the Northern Block and Central Asian Orogenic Belt (CAOB).

title: Preparation and characterization of dual-responsive spiropyran-based random copolymer brushes via surface-initiated atom transfer radical polymerization

description: Silica nanoparticles (SiO<sub>2</sub>) were grafted with the precursor random copolymer of 1′-(2-acryloxyethyl)-3′,3′-dimethyl-6-nitrospiro-(2H-1-benzopyran-2,2′-indoline) (SPMA) and tert-butyl methacrylate (tBMA) by surface-initiated atom transfer radical polymerization (SI-ATRP), and SiO<sub>2</sub>-g-P(SPMA-co-methacrylic acid (MAA)) was obtained via chemical hydrolysis of the resulting precursor random copolymer in acidic conditions. From transmission electron microscopy, we observed the spherical morphology of monodispersed silica nanoparticles and core-shell structure of SiO<sub>2</sub>-g-P(SPMA-co-MAA). Energy dispersive spectroscopy, Fourier transform infrared spectra, X-ray photoelectron spectroscopy, and the thermogravimetric analysis indicated that the polymer had been successfully grafted onto the surface of silica nanoparticles. The dual-responsive properties were characterized by means of ultraviolet-visible spectrophotometer and dynamic light scattering. The average hydrodynamic diameter of SiO<sub>2</sub>-g-P(SPMA-co-MAA) increased from 185.7 to 212.7 nm under ultraviolet light irradiation for 5 min. Also, the particle size of SiO<sub>2</sub>-g-P(SPMA-co-MAA) increased with the rising pH value of surrounding condition.
