Abstract: There is provided a method of forming a patterned structure on a substrate. The method includes: forming a resist layer on the substrate, the resist layer being a negative tone resist; exposing a first portion of the resist layer to a focused electron beam to form a modified first portion, the modified first portion defining a boundary of a second portion of the resist layer; performing a plasma treatment on a surface of the resist layer, including on a surface of the second portion of the resist layer to form a modified surface portion of the second portion of the resist layer, resulting in a plasma treated resist layer; and performing development of the plasma treated resist layer to form the patterned structure on the substrate corresponding the second portion of the resist layer.

Abstract: A method of detecting cyber attacks on a cyber physical system is disclosed, and the system includes at least one computing device coupled to at least one sensor and/or actuator for controlling a physical process. The method comprises: deriving at least one invariant for the computing device, based on a system design of the system or computer code configured to control the system in relation to the physical process or data collected from the system during testing or operation of the system, the invariant defining a set of conditions that enable determination from the sensor and/or actuator regarding process anomalies of the physical process being controlled; configuring the invariant as corresponding computer code; and executing the invariant as the computer code on the computing device to monitor the physical process via the sensor and/or actuator and detect the process anomalies for detecting the cyber attacks.

Abstract: An electrospun fibre comprising: a polymer matrix; and a plurality of photoluminescent molecules in the polymer matrix, wherein each photoluminescent molecule comprises a hydrophobic portion and a charged portion. A method for producing an electrospun fibre, the method comprising: preparing a polymer matrix; adding a plurality of photoluminescent molecules to the polymer matrix to form a spinable solution, each photoluminescent molecule comprises a hydrophobic portion and a charged portion; and electrospinning the spinnable solution to produce the electrospun fibre. An example of the photoluminescent molecule is 1-(1-(8-pyridiniumoctyloxy)-2, 3,4,5-tetraphenylcyclopenta-2,4-dienyl)benzene chloride (structure shown below), a molecule having aggregation-induced emission (AIE) properties.

Abstract: The present invention relates to an apparatus for tracking a device comprising a magnet as the device is inserted through a subject. The apparatus is wearable by the subject and comprises a unit configured to conform to the subject. The apparatus further comprises magnetic sensors arranged with the unit. In use, the magnetic sensors detect magnetic fields of the magnet and the detected magnetic fields are processed to determine a position of the magnet. This allows tracking of the device as the device is inserted through the subject.
