Low levels of classical BSE infectivity in rendered fat tissue
BSE infectivity in mesentery fat is most likely associated with embedded nervous tissue. To prove this mesentery containing celiac ganglion was taken from oral BSE infected cattle in different stages of the disease and from one control animal.

Safe reinforcement learning for dynamical systems using barrier certificates
Safety control is a fundamental problem in policy design. Basic reinforcement learning is effective at learning policy with goal-reaching property. However, it does not guarantee safety property of the learned policy.

The potential of chemical bonding to design crystallization and vitrification kinetics
Tailoring the crystallization kinetics of materials is important for targeting applications. Here the authors observe a remarkable dependence of crystallization and vitrification kinetics and attribute it to systematic bonding changes for a class of ...

RF-Access: Barrier-Free Access Control Systems with UHF RFID
Traditional RFID-based access control systems use flap barriers to help manage pedestrian access and block unauthorized staff at any entrance, which requires visitors to swipe their cards individually and wait for the opening of the blocking body ...

A Novel Technique for Laryngotracheal Reconstruction for Idiopathic Subglottic Stenosis [PDF]
Idiopathic subglottic stenosis is the most challenging condition in the field of upper airway reconstruction. We describe a successful novel technique for enlarging the airway space at the site of the laryngotracheal anastomosis in very high-level ...

Lack of effective immune infiltration represents a significant barrier to immunotherapy in solid tumors. Thus, solid tumor‐enriched death receptor‐5 (DR5) activating antibodies, which generates tumor debulking by extrinsic apoptotic cytotoxicity, remains

According to recent guidelines, the mainstay of urate-lowering therapies remains xanthine oxidase inhibition. However, some patients with gout show failure to achieve the predefined target of 5-6 mg/dl with xanthine oxidase inhibitors alone, so alternative drugs are needed.

Systems control theory applied to natural and synthetic musical sounds [PDF]
Systems control theory is a far developped field which helps to study stability, estimation and control of dynamical systems. The physical behaviour of musical instruments, once described by dynamical systems, can then be controlled and numerically ...

A new model-free setting and the corresponding "intelligent" P and PD controllers are employed for the longitudinal and lateral motions of a vehicle. This new approach has been developed and used in order to ensure simultaneously a best profile tracking ...
