The prevailing view of intra-Golgi transport is cisternal progression, which has a key prediction--that newly arrived cargo exhibits a lag or transit time before exiting the Golgi. Instead, we find that cargo molecules exit at an exponential rate proportional to their total Golgi abundance with no lag. Incoming cargo molecules rapidly mix with those already in the system and exit from partition...

An essential lifeline to Bangladesh's robust economy, Chittagong Port in Bangladesh, was the subject of an insightful visit May 2023. expert team comprising three academicians (professors) and two industry experts from Bangladesh Freight Forwarders Association (BAFFA) embarked on explorative journey understand heart nation's supply chain examine intricate operations that make this port economic...

conclusion according to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely. we resolve that routine ultrasound of the puncture site is a quick, effective and safe procedure. the complication rate is very low. the us-assisted percutaneous liver biopsy should be used for all cases. results a total of 1018 patients we...

The coat complex COPII forms vesicles at the endoplasmic reticulum to transport a variety of cargo proteins to the Golgi structure. Recent biochemical and structural studies reveal the molecular mechanism of cargo protein recognition by COPII components. Furthermore, there are at least two distinct ER-to-Golgi transport carrier structures carrying different cargo proteins in yeast and mammalian...

Overcapacity of seaport infrastructure has been a common issue in many countries recent years. Cautious investment decisions shall be made on the basis realistic capacity evaluation and productivity improvement existing ports. However, operational analysis is not always easy, especially for multipurpose terminals which are commonly seen developing countries. These small-scaled seaports handle d...

Cargo terminals are the gateways for entrance of commodities into the transportation network. Therefore, locating them in optimal location could have a major impact on the cost effectiveness and efficiency of transport, traffic safety and reduction in environmental pollutions. Due to the presence of a large number of parameters involved and the existing uncertainties, decision making in this fi...

Much effort has been devoted to the study of swarming and collective navigation of micro-organisms, insects, fish, birds and other organisms, as well as multi-agent simulations and to the study of real robots. It is well known that insect swarms can carry cargo. The studies here are motivated by a less well-known phenomenon: cargo transport by bacteria swarms. We begin with a concise review of ...

Since the end of 2019, outbreak COVID-19 has severely affected port production and operation. There is little research on systematic impact assessment. This study took Shanghai Port as an example evaluated under different scenarios through establishing a System Dynamics model. It found that epidemic mainly greater passenger transport, but less cargo transport. The ports with function transporta...
