From Han tradition to Tang elegance
This long paper is the comprehensive essay to the exhibition China at the court of the emperors. Unknown masterpieces from Han Tradition to Tang elegance (25-907), held at Palazzo Strozzi, Florence, in Spring 2008.
It thoroughly explains the development of the arts in China from the Han to the Tang dynasties against the historical and cultural context of the time, underlying the new perspective recently put forward on the basis of the latest archaeological excavations. These have driven scholars to regard the period of division between Han and Tang no longer as a ‘dark’ epoch of unrest, during which the country was politically and culturally fragmented, but instead as a moment of regeneration and flowering of the arts, stimulated by intercultural exchanges with Rome, Persia, India and Central Asia. From this new viewpoint, it appears clear that the great renaissance of the seventh to eighth centuries was the culmination of a long process that had germinated in the second to third centuries

Paratypes: 5♂♂ 3♀♀, same data as for the holotype. (SHNU, cPut) Description. BL: 4.0– 4.3 mm, FL: 1.9–2.1 mm. HW: 0.86–0.90 mm, PL: 0.69–0.73 mm, PW: 0.63–0.69 mm, EL: 0.66–0.71 mm, EW: 0.70–0.79 mm, SL: 0.50–0.53 mm. Similar to S. lizipingus sp. nov. in most respects, but different in the following characters: head 1.11–1.23 times as wide as elytra, lateral portion of head with distinct microsculptures; pronotum relatively longer with PL/ PW: 1.04–1.13; elytra relatively narrower with 0.87–0.93 times as long as wide; elytral disk impressions shallower; punctation of abdominal tergites relatively smaller and slightly sparser than that of S. lizipingus sp. nov. Male. Sternite VIII (Fig. 17) with emargination in the middle of posterior margin; sternite IX (Fig. 18) with very long apicolateral projections, posterior margin serrate. Aedeagus (Figs. 19, 20) with median lobe stout, apical sclerotized area broadly and bluntly, pointed at apex; expulsion clasps large; parameres distinctly longer than median lobe, swollen at apical third, each with 9–12 setae on apico-internal margins. Female. sternite VIII (Fig. 21) slightly prominent at middle of posterior margin; spermatheca (Fig. 22)sclerotized, basal porch very large, spermathecal duct with two bents, apical chamber large and capsule very large. Distribution. China (Sichuan). Remarks. The new species is similar to S. lizipingus sp. nov. both occurred in same locality, and it can be distinguished from the latter by the exterior characters indicated above and the different sexual characters. It is also similar to S. zhuxiaoyui Tang & Zhao, 2008, S. pectorifossatus Tang & Zhao, 2008 and S. erlangshanus Tang & Zhao, 2008 from Sichuan, and can be distinguished from S. zhuxiaoyui and S. erlangshanus by more confluent pronotal punctation, from S. zhuxiaoyui also by larger body size (FL: 1.5–2.0 mm in S. zhuxiaoyui), from S. erlangshanus by lacking distinct subbasal and subapical pronotal impressions and abdominal tergites mostly with microsculptures, from S. pectorifossatus by darker elytral coloration and sparser abdominal punctation. Etymology. The specific name is derived from the lartin word “ fuscus ” after its dark coloration.Published as part of Hu, Cheng-Zhi & Tang, Liang, 2018, Notes on the Stenus indubius group with descriptions of four new species from China (Coleoptera, Staphylinidae), pp. 341-350 in Zootaxa 4471 (2) on pages 345-346, DOI: 10.11646/zootaxa.4471.2.6, http://zenodo.org/record/143976
Collective behavior of crowded drops in microfluidic systems
Droplet microfluidics, in which microdroplets serve as individual reactors, has enabled a wide range of high-throughput biochemical processes. Unlike solid wells typically used in current biochemical assays, droplets are subject to instability and can undergo breakup, especially under fast flow conditions. Although the physics of single drops has been studied extensively, the flow of crowded drops or concentrated emulsions - where droplet volume fraction exceeds ∼80% - is relatively unexplored in microfluidics. In this paper and the related invited lecture from the 74th Annual Meeting of the American Physical Society's Division of Fluid Dynamics, we describe the collective behavior of drops in a concentrated emulsion by tracking the dynamics and the fate of individual drops within the emulsion. At the slow flow limit of the concentrated emulsion, we observe an unexpected order, where the velocity of individual drops in the emulsion exhibits spatiotemporal periodicity. This periodicity is surprising from both fluid and solid mechanics points of view. We show the phenomenon can be explained by treating the emulsion as a soft crystal undergoing plasticity, in a nanoscale system comprising thousands of atoms as modeled by droplets. Our results represent a type of collective order which can have practical use in on-chip droplet manipulation. As the flow rate increases, the emulsion transitions from a solidlike to a liquidlike material, and the spatiotemporal order in the flow is lost. At the fast flow limit, droplet breakup starts to occur. We show that droplet breakup within the emulsion follows a probability distribution, in stark contrast to the deterministic behavior in classical single-drop studies. In addition to capillary number and viscosity ratio, breakup probability is governed by a confinement factor that measures drop size relative to a characteristic channel length. The breakup probability arises from the time-varying packing configuration of the drops. Replacing surfactant with nanoparticles as droplet stabilizers suppresses breakup and increases the throughput of droplet processing by >300%. Strategic placement of an obstacle suppresses breakup by >103-fold. Finally, we discuss recent progress in computation methods for recapitulating the flow of concentrated emulsions
