Question-Driven Methods or Method-Driven Questions? How We Limit What We Learn by Limiting What We Ask

open access: yesJournal of MultiDisciplinary Evaluation, 2015
The “methodologically manic-obsessive” evaluation profession and the metrics- and measures-obsessed lay users of evidence have managed to seriously limit the value of what we learn from evaluation.

Continuum Limit of Scalar Masses and Mixing Energies [PDF]

open access: yes, 1998
We evaluate the continuum limit of the valence approximation to the mass of scalar quarkonium and to the scalar quarkonium-glueball mixing energy for a range of different quark masses.

LEDs driven by AC without transformers or rectifiers

open access: yesScientific Reports, 2021
We explore the driving of LEDs by untransformed AC. An extreme case is driving 1.9 V threshold (red) LEDs with UK mains, peak voltage 325 V. Commonly, driving is by transformed, rectified (DC) supply with a series resistor (where a significant fraction ...

Off-critical lattice models and massive SLEs [PDF]

open access: yes, 2009
We suggest how versions of Schramm’s SLE can be used to describe the scaling limit of some off-critical 2D lattice models.

Studying The Effects Of Transcranial Direct Current Stimulation In Stroke Recovery Using Magnetic Resonance Imaging

open access: yesFrontiers in Human Neuroscience, 2013
Transcranial direct current stimulation (tDCS) is showing increasing promise as an adjunct therapy in stroke rehabilitation. However questions still remain concerning its mechanisms of action, which currently limit its potential. Magnetic Resonance (MR)

On the weak limit of compact operators on the reproducing kernel Hilbert space and related questions

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
By applying the so-called Berezin symbols method we prove a Gohberg- Krein type theorem on the weak limit of compact operators on the non- standard reproducing kernel Hilbert space which essentially improves the similar results of Karaev [5]: We also in ...

Noninvasive prenatal testing: limitations and unanswered questions [PDF]

open access: yesGenetics in Medicine, 2014
The clinical use of noninvasive prenatal testing to screen high-risk patients for fetal aneuploidy is becoming increasingly common. Initial studies have demonstrated high sensitivity and specificity, and there is hope that these tests will result in a reduction of invasive diagnostic procedures as well as their associated risks.

The Tensor Track, III [PDF]

open access: yes, 2013
We provide an informal up-to-date review of the tensor track approach to quantum gravity. In a long introduction we describe in simple terms the motivations for this approach.
