MODELING AND CONTROL FOR DEADLOCK-FREE OPERATION OF SINGLE-ARM CLUSTER TOOLS WITH CONCURRENTLY PROCESSING MULTIPLE WAFER TYPES VIA PETRI NET

Modeling and Control for Deadlock-Free Operation of Single-Arm Cluster Tools With Concurrently Processing Multiple Wafer Types via Petri Net

Nowadays, cluster tools tend to concurrently process multiple types of wafers with similar recipes in order to improve their utilization and flexibility in semiconductor manufacturing.Different wafer types may have different wafer flow patterns, resulting in that cluster tools are deadlock-prone.It is challenging to develop a general method to solv

Dietary Fiber and Bacterial SCFA Enhance Oral Tolerance and Protect against Food Allergy through Diverse Cellular Pathways

The incidence of food allergies in western countries has increased dramatically in recent decades.Tolerance to food antigens relies on mucosal CD103+ dendritic cells (DCs), which promote differentiation of regulatory T (Treg) cells.We show that high-fiber feeding in mice improved oral tolerance and protected from T-Shirt food allergy.High-fiber fee
