Abstract: Various embodiments of the present disclosure provide a scan-based architecture for register-transfer-level (RTL) or gate-level designs that improves the security of scan chain-based design-for-testability (DFT) structures. In various embodiments, the scan-based architecture includes invisible scan chains that are hidden in such a way that an attacker cannot easily identify or locate the invisible scan chains for exploitation and revealing internal secure information of the design. The invisible scan chains are dynamically configurable into a scan chain with select flip-flops, such that scan paths of the invisible scan chains may be different between different designs, chips, or testing operations. Various embodiments further employ key-based obfuscation by combining a scan control finite state machine with existing state machines within a design, which improves design security against unauthorized use and increases confidentiality.

The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.

Abstract: This invention is related to the field of PCSK9 biology and the composition and methods of use of small organic compounds as ligands for modulation of PCSK9 biological activity. In particular, the invention provides compositions of small organic compounds that modulate circulating levels of low density lipoproteins by altering the conformation of the protein PCSK9. Binding these small organic compound ligands to PCSK9 alters the conformation of the protein, modifying the interaction between PCSK9 and an endogenous low density lipoprotein receptor, and can lead to reduced or increased levels of circulating LDL-cholesterol. High LDL-cholesterol levels are associated with increased risk for heart disease. Low LDL-cholesterol levels may be problematic in other conditions, such as liver dysfunctions; thus, there is also utility for small organic compound ligands and can raise LDL levels.
