The analysis of cetacean strandings can provide fundamental information about species diversity and composition in a particular region. The present study collected and analyzed cetacean strandings, bycatches and rescues along the western coast of the Taiwan Strait, China, from 2010 to 2015. In total, 48 records, including 37 strandings, 8 bycatches and 3 rescues, involving 13 known species were collected. Among them, Indo-Pacific humpback dolphins（Sousa chinensis） and finless porpoises（Neophocaena phocaenoides） were the most common species, consisting of 31.3% and 25%, respectively. Notably, 10 out of the 48（20.8%） records were collected from the Pingtan Island and included 3 species of Mysticeti and 4 species of Odontoceti. Finally, we compared the cetacean species composition between the western and eastern coasts of the Taiwan Strait; 31 cetacean species occurred in the Taiwan Strait, indicating a relatively high cetacean diversity in this region. Systematic field surveys are urgently needed to explore the cetacean species composition, population stock and the related habitat status in the Taiwan Strait, which may improve conservation management in the future.

Brownian motion was discovered by the botanist Robert Brown in 1827, and the theoretical model of Brownian motion has real-world applications in fields such as mathematics, economics, physics and biology. It is the presumably random motion of particles suspended in a liquid or a gas that results from their bombardment by fast-moving atoms or molecules, but the exact mechanism of Brownian motion still remains one of the unresolved mysteries in physics. Here circadian and seasonal changes in long-term macroscopic anisotropic (asymmetric) Brownian motion of a toluidine blue colloid solution in water in two dimensions were identified, suggesting that such an anisotropic Brownian motion may be related to an effect of the directional movement of “Universe field”, and thereby providing new interpretations and potential applications of Brownian motion.

In this study,cellulose nanofibrils(CNF)of high charge(H-P-CNF)and screened size(H-P-CNF-S)were fabricated by increasing the charge of phosphorylated cellulose nanofibrils(P-CNFs)during the pre-treatment step of CNF *** show that the H-P-CNF have a significantly higher charge(3.41 mmol g^(-1))compared with P-CNF(1.86 mmol g^(-1)).Centrifugation of H-P-CNF gave a supernatant with higher charge(5.4 mmol g^(-1))and a reduced size(H-P-CNF-S).These tailored nanocelluloses were added to polyvinyl alcohol(PVA)solutions and the suspensions were successfully coated on porous polysulfone(PSf)supports to produce thin-film nanocomposite *** humid mixed gas permeation tests show that CO_(2)permeability increases for membranes with the addition of H-P-CNF-S by 52%and 160%,compared with the P-CNF/PVA membrane and neat PVA membrane,respectively.
