Dermatology Research Centre, Department of Medicine & Therapeutics, The Chinese University of Hong Kong, Shatin, N.T., Hong Kong Excision of superficial and slightly deeper cutaneous lesion can be performed by shaving the lesion using a razor blade. After induction of local anaesthesia, normal saline is injected to make the lesion bulge. A peripheral portion of the lesion is curetted for assess...

Don Hoi Lord, a coastal wetland in the upper gulf of Thailand, is famous for the razor clam (Solen regularis), which is a source of food and income for local fishermen. However, the razor clam population is significantly decreasing so the aim of this study was to analyze the razor clam fishery and develop a management plan engaging the different stakeholders in collective discussions. A partici...

A central question in the empirical sciences is; given a body of data how do we best attempt to make predictions? There are subtle differences between current approaches which include Minimum Message Length (MML) and Solomonoff’s theory of induction [24]. The nature of hypothesis spaces is explored and we observe a correlation between the complexity of a function and the frequency with which it...

The technique consists of forming a surface pitot-tube by placing a small segment of razor blade on the surface with its tapered cutting edge above a static-pressure hole. The effects of limited changes in the razor-blade geometry on the measured pressure have been determined in a two-dimensional turbulent boundary layer and a calibration curve for a particular standardised geometry deduced. Th...

The in vivo operation of a speaking valve consists of two stages: 1) air passes through the razor-thin slit, the dome opens and the patient can speak; 2) the dome is closed and the patient cannot speak. The valve is thus subject to fatigue, as its service life is made up of a certain number of opening/closing cycles. Two types of valve were investigated: the Staffieri valve and a new valve prot...

The fracture toughness is a critical material property for the pyrolytic carbon materials used in mechanical heart-valve prostheses; however, making accurate toughness measurements has traditionally been problematic due to difficulties in fatigue precracking specimens. In this work, a simple, effective, and reliable precracking method is presented where a sharp precrack is "popped in" from a ra...

Informally, Occam’s razor states, “Given two hypotheses which equally agree with the observed data, choose the simpler”, and has become a central guiding heuristic in the empirical sciences and in particular machine learning. We criticize previous arguments for the validity of Occam’s razor. The nature of hypotheses spaces is explored and we observe a correlation between the complexity of a con...
