OBJECTIVES To assess the accuracy of a new noninvasive temporal artery (TA) thermometer in infants; to compare the accuracy of the TA thermometer with that of a tympanic thermometer, using rectal thermometry as the criterion standard; and to compare the tolerability of the TA thermometer with that of the tympanic and rectal thermometers. DESIGN Prospective evaluation of the accuracy of TA and...

BACKGROUND Current clinical targets for transcranial magnetic resonance-guided focused ultrasound (tcMRgFUS) are all located close to the geometric center of the skull convexity, which minimizes challenges related to focusing the ultrasound through the skull bone. Non-central targets will have to be reached to treat a wider variety of neurological disorders and solid tumors. Treatment envelope ...

BACKGROUND Tympanic thermometry has come as a suitable alternative to traditional thermometry because of its safety and ease of use. However, it is still yet to gain wide acceptance in African settings due to conflicting results on its accuracy, thus rectal thermometry remains the gold standard in the newborn. The aim of this study was to compare tympanic and rectal temperatures in term Nigeria...

A new concept using a near-field thermometry sensor is presented, employing atipless microcantilever experimentally validated for an aqueous medium within approximatelyone cantilever width from the solid interface. By correlating the thermal Brownian vibratingmotion of the microcantilever with the surrounding liquid temperature, the near-fieldmicroscale temperature distributions at the probing ...

In the NBS/NIST Gas Thermometry program, constant-volume gas thermometers, a unique mercury manometer, and a highly accurate thermal expansion apparatus have been employed to evaluate temperatures on the Kelvin Thermodynamic Temperature Scale (KTTS) that correspond to particular temperatures on the 1968 International Practical Temperature Scale (IPTS-68). In this paper, we present a summary of ...

The spatial resolution of infrared thermometry is limited by diffraction to dimensions close to the wavelength of the collected infrared radiation, typically 5 μm at room temperatures. Thermal properties variations, temperature gradients, and defects with dimensions smaller than the diffraction limit are inaccessible to far-field infrared thermometry. This work demonstrates a near-field method ...

The Colorado Plateau’s complex landscape has motivated over a century of debate, key to which is understanding the timing and processes surface uplift greater Plateau region, its interactions with erosion, drainage reorganization, evolution. Here, we evaluate what known about history from prior paleoelevation estimates region by synthesizing evaluating 1) in context inferred geologic, geomorphi...
