A double forecasting model based on conditional expectation is proposed through probability distribution of port cargo throughput. A compound variable, being composed of the number of cargo ships arriving at the port and the operating efficiency of handling equipment, is constructed. The port cargo throughput is the sum of all compound variables which indicated the cargo throughput each time wh...

The endoplasmic reticulum (ER) is the site of synthesis of secreted and membrane proteins. To exit the ER, proteins are packaged into COPII vesicles through direct interaction with the COPII coat or aided by specific cargo receptors. Despite the fundamental role of such cargo receptors in protein traffic, only a few have been identified; their cargo spectrum is unknown and the signals they reco...

an elliptical tank cross-section is formulated to explore and optimization method, based on a real-coded genetic algorithm to enhance the roll stability limit of a tank vehicle. a shape genetic algorithm optimization problem is applied to minimize the overturning moment imposed on the vehicle due to c.g. height of the liquid load, and lateral acceleration and cargo load shift . the minimization...

The Sar1 GTPase is an essential component of COPII vesicle coats involved in export of cargo from the ER. We report the 1.7-A structure of Sar1 and find that consistent with the sequence divergence of Sar1 from Arf family GTPases, Sar1 is structurally distinct. In particular, we show that the Sar1 NH2 terminus contains two regions: an NH2-terminal extension containing an evolutionary conserved ...

The cargo motion in living cells transported by two species of motor protein with different intrinsic directionalities is discussed in this study. Similarly to single motor movement, the cargo steps forward and backward along a microtubule stochastically. Recent experiments found that cargo transportation by two motor species has a memory; it does not change its direction as frequently as expec...

We evaluated 10 years of reported hazardous cargo incident information from the U.S. Air Force and Naval Safety Centers. In this first of two papers describing the hazardous cargo problems reported by the two services, we describe types of aircraft and types of hazardous cargo involved in incidents not causing aircraft mishaps. Normally, hazardous cargo must be manifested as such and no passeng...

Autophagy is a process delivering cytoplasmic components to lysosomes for degradation. Autophagy may, however, play a role in unconventional secretion of leaderless cytosolic proteins. How secretory autophagy diverges from degradative autophagy remains unclear. Here we show that in response to lysosomal damage, the prototypical cytosolic secretory autophagy cargo IL-1β is recognized by speciali...

Speed economy, proposed by Japanese scholars Masaki Tamura, refers to get the cost savings flow by accelerating the transaction process [1], which brings the a large market space to the cargo/express delivery industry [2]. Due to the rapidly growth of China air cargo/express market and the ongoing increasingly opening up of the sky, international cargo/express giants have set up their hubs in C...

An international study of the airport choice factors for non-integrated cargo airlines By John Gardiner Recent forecasts predict that the current number of all-cargo aircraft worldwide will more than double over the next 20 years, spurred on by trends such as reduced passenger belly hold capacity on short and medium haul routes and a growing recognition of the profit potential of cargo by airli...

This investigation has been carried out under a contract awarded by the Netherlands Directorate-General of Civil Aviation (RLD), contract number LI/99.121/2. Summary Previous research has suggested that cargo operators suffer a disproportionally high number of accidents. The degree of unsafety could however not properly be quantified due to lack of data. The objective of the underlying study wa...
