Multi-probe robotic positioner for cryoablation in MRI
… device for faster and more accurate targeting of multiple probes during cryoablation and other percutaneous interventions performed in closed bore magnetic resonance (MR) imaging systems. The device is intended to be mounted onto a Siemens 110 mm MR loop coil that rests on the patient and contains …

Development of a Multi-Probe Kelvin Scanner Device for Industrially-Relevant Characterization of Surface-Activated Carbon Fiber Reinforced Thermoplastic Composites
… discovered through the use of scanning probe microscopy, a multiple-probe Kelvin scanning (MPKS) device has been developed that can assess the uniformity of the activation state of plasma-treated CFRTP surfaces. The device can distinguish between control and plasma-treated samples and …

Scanning Probe Array Development for Dip Pen Nanolithography
… used to install the arrays in AFMs modified for multi-probe applications. The arrays were used to write patterns of 1-octadecanethiol on gold surfaces with line widths as small as 25nm, write speeds as fast as 20mum/sec, and up to four patterns overlapping the same region.

Feasibility of Single-Point Excitation Ultrasonic Force Microscopy
<p>We propose Multi-Probe Ultrasonic Force Microscopy (UFM) to create and detect the motion of tip-induced surface waves and thereby study nanoscale surface dynamics. Before committing to the construction of an instrument, we investigate the theoretical feasibility of such a novel instrument to …

Numerical Chromosome Abnormalities in Sperm From Oligoasthenoteratozoospermic Patients and Fertile Males
… cytogenetic make-up of sperm from OAT patients, multi-probe, multi-color FISH was performed to determine aneuploidy.</p> <p>The introduction of intracytoplasmic sperm injection (ICSI) has revolutionized protocols used in in vitro fertilization centers. The pregnancies resulting from ICSI suggest …

THE EFFECTS OF AGE AND HETEROCHROMATIN ON FREQUENCIES OF ACQUIRED CHROMOSOMAL ANEUPLOIDY IN UNCULTURED HUMAN LEUKOCYTES
… that loss of the Y chromosome is likely to be a multifactorial phenotype, being influenced by both genetic and environmental factors. An analysis of acquired aneuploidy frequencies for 13 autosomes in men showed that only one autosome, chromosome 3, had an age-related increase in acquired …

High-strength transformation-induced plasticity steels with reverted interlath austenite
… scanning calorimetry measurements and multi-probe microstructure analysis, and its mechanical impacts are discussed. In method (i), the reversion kinetics increases significantly by promoting displacive transformation. The defect development during displacive reversion can help increase …

Development of a combined multi-sensor/signal processing architecture for improved in-situ quantification of the charge balance of natural waters
… and SO2-4 . The instrument is built on a hybrid multi-probe / signal processing architecture and is implemented using commercial sensor hardware (primarily ion-selective electrodes (ISEs)) paired with a novel neural network processor designed to take advantage of a priori chemical knowledge about …

The Weak Lensing Hat-Trick: Constraining Cosmology with Galaxy, CMB, and Kinematic Lensing
… present how weak lensing, combined with other probes, can play a crucial role in mitigating systematics and understandingdark energy and the growth of structure in the universe. Specifically, I will introduce “Kinematic Lensing” (KL). This novel technique combines imaging and galaxy kinematics …

Discerning nonlinear brain dynamics from EEG : an application to autistic spectrum disorder in young children
… neurotypical subjects, based on the analysis of multi-probe EEG time-series from male children aged 3-5 years. The methods applied are all ones that take explicit account of the intrinsically non-linear, open, and time-variable nature of the system. Time-frequency representations were first …

Quantum Hall transport in graphene and its bilayer
… varying perpendicular and in-plane fields, we probe the spin-active components of the excitations in total fields of up to 45 Tesla. Our results strongly suggest that the 𝝂 = 0 quantum Hall state in single layer graphene is not spin polarized, while a spin-polarized state with spin-flip …

Fusion of multiprobe NDT data.
… the synergistic use of information from multiple instruments will provide a consensus assessment and help in decision making by providing a final output, with associated probabilities which may support or refute information from one or multiple sensors. The process used to combine …
