西南日本秋吉带石炭系高山(Ko-yama)灰岩群的石炭纪(Visean-Moscovian)牙形石序列(英文)

The Carboniferous conodont faunal succession of the lower part of Ko-yama Limestone Group was studied.The confirmed upper Visean-lower Moscovian lithostratigraphy of the group is characterized by the clastic carbonates with common association of the basaltic pyroclastics and some intercalation of spicular chert beds.The faunal succession of Gnathodus semiglaber(upper Visean),Gnathodus praebilineatus-Lochriea multinodosa(upper Visean),Lochriea ziegleri-Gnathodus girtyi girtyi s.l.(lower Serpukhovian),Neoganthodus symmetricus-Idiognathodus primulus(middle-upper Bashkirian),and Idiognathoides convexus-Gondolella clarki(lower Moscovian) faunas,appears in concordance with the lithostratigraphic order.The faunas are correlative with those from the conodont zones of the Hina,Atetsu,Akiyoshi and Omi limestone groups in the Akiyoshi Belt.The Visean/Serpukhovian boundary of the section was recognized by the FAD of Lochriea ziegleri.

Effect of precipitation/re-dissolution processes from the supersaturated solution on the intestinal absorption of poorly water-soluble drugs

As one of the possible technologies to improve the oral absorption of poorly water-soluble drugs, supersaturable formulation, which enables to dissolve the drug to the higher concentration than their equilibrium solubility, is now attracting the attention (1)This include salt-formation, soliddispersion, co-crystallization or the use of amorphous form.Since supersaturation is a thermodynamically metastable state,supersaturated solution has a high potential to precipitate. Some pharmaceutical excipients.

Towards an ultrafast 3D imaging scanning LiDAR system:a review

Light detection and ranging(LiDAR),as a hot imaging technology in both industry and academia,has undergone rapid innovation and evolution.The current mainstream direction is towards system miniaturization and integration.There are many metrics that can be used to evaluate the performance of a LiDAR system,such as lateral resolution,ranging accuracy,stability,size,and price.Until recently,with the continuous enrichment of LiDAR application scenarios,the pursuit of imaging speed has attracted tremendous research interest.Particularly,for autonomous vehicles running on motorways or industrial automation applications,the imaging speed of LiDAR systems is a critical bottleneck.In this review,we will focus on discussing the upper speed limit of the LiDAR system.Based on the working mechanism,the limitation of optical parts on the maximum imaging speed is analyzed.The beam scanner has the greatest impact on imaging speed.We provide the working principle of current popular beam scanners used in LiDAR systems and summarize the main constraints on the scanning speed.Especially,we highlight the spectral scanning LiDAR as a new paradigm of ultrafast LiDAR.Additionally,to further improve the imaging speed,we then review the parallel detection methods,which include multiple-detector schemes and multiplexing technologies.Furthermore,we summarize the LiDAR systems with the fastest point acquisition rate reported nowadays.In the outlook,we address the current technical challenges for ultrafast LiDAR systems from different aspects and give a brief analysis of the feasibility of different approaches.

High-power sub-picosecond all-fiber laser source at 1.56 μm

We demonstrate an all-fiber, high-power, and high stability ultrafast laser source operating at 1563 nm. A highly stable, self-starting carbon nanotube（CNT） mode-locked femtosecond fiber laser is used as the seed source. The amplifier stage uses a fiber chirped pulse amplification configuration. The main power amplifier is based on a cladding-pumped Er–Yb co-doped fiber with 10 μm active single-mode core diameter. The laser source provides 3.4 W average output power at 75 MHz repetition rate. The pulses are compressed to 765 fs by a low-loss transmission grating pair. The robust, compact, and high-power 1560 nm fiber laser source can be used for eye surgery and solar cell micromachining.
