Journal Article
(2008). Cytoplasmic CUG RNA foci are insufficient to elicit key DM1 features. PloS one, e3968 -?. https://doi.org/10.1371/journal.pone.0003968

The genetic basis of myotonic dystrophy type I (DM1) is the expansion of a CTG tract located in the 3' untranslated region of DMPK. Expression of mutant RNAs encoding expanded CUG repeats plays a central role in the development of cardiac disease in...

Variational bayesian generative topographic mapping (2008)
Journal Article
(2008). Variational bayesian generative topographic mapping. Journal of Mathematical Modelling and Algorithms, 371 -387. https://doi.org/10.1007/s10852-008-9088-7

General finite mixture models are powerful tools for the density-based grouping of multivariate i.i.d. data, but they lack data visualization capabilities, which reduces their practical applicability to real-world problems. Generative topographic map... Read More about Variational bayesian generative topographic mapping.

Evidence of local moment formation in Co-based Heusler alloys (2008)
Journal Article
Telling, N. D., Keatley, P. S., van der Laan, G., Hicken, R. J., Arenholz, E., Sakuraba, Y., …Miyazaki, T. Evidence of local moment formation in Co-based Heusler alloys. Physical review B: Condensed matter and materials physics, 78(18), https://doi.org/10.1103/physrevb.78.184438

We examine the formation of local moments in Heusler alloys of the composition
Co2MnZ (where Z=Si or Al) using the combined techniques of x-ray magnetic circular and linear dichroism. The existence of local moments in half-metallic Heusler alloys i... Read More about Evidence of local moment formation in Co-based Heusler alloys.

Multiproject–multicenter evaluation of automatic brain tumor classification by magnetic resonance spectroscopy (2008)

(2008). Multiproject–multicenter evaluation of automatic brain tumor classification by magnetic resonance spectroscopy. Magnetic Resonance Materials in Physics, Biology and Medicine, 5 - 18. https://doi.org/10.1007/s10334-008-0146-y

JUSTIFICATION: Automatic brain tumor classification by MRS has been under development for more than a decade. Nonetheless, to our knowledge, there are no published evaluations of predictive models with unseen cases that are subsequently acquired in d...

THE OXIDATION STATE OF COPPER AND COBALT IN CARROLLITE, CuCo2S4 (2008)
Journal Article
Pattrick, R. A., Coker, V. S., Pearce, C. I., Telling, N. D., & van der Laan, G. (2008). THE OXIDATION STATE OF COPPER AND COBALT IN CARROLLITE, CuCo2S4. Canadian Mineralogist, 46(5), 1317-1322. https://doi.org/10.3749/canmin.46.5.1317

Using X-ray absorption spectroscopy (XAS) at the Cu L2,3 and Co L2,3 edges, we demonstrate that the valence state of copper in the thiospinel carrollite (CuCo2S4) is Cu+ with a d count of Cu d9.8. The Co has a d count of d6.4, so that the highly cova... Read More about THE OXIDATION STATE OF COPPER AND COBALT IN CARROLLITE, CuCo2S4.

Platelet-Derived Growth Factor Stimulates Osteoprotegerin Production in Osteoblastic Cells (2008)
Journal Article
(2008). Platelet-Derived Growth Factor Stimulates Osteoprotegerin Production in Osteoblastic Cells. Journal of Cellular Physiology, 350-354. https://doi.org/10.1002/jcp.21600

Osteoprotegerin (OPG) is a major regulator of osteoclastogenesis, bone resorption and vascular calcification. OPG is produced by various cell types including mesenchymally derived cells, in particular, osteoblastic cells. Here we show OPG production...

Interface alloying effects in the magnetic properties of Fe nanoislands capped with different materials (2008)
Journal Article
Huttel, Y., Navarro, E., Telling, N. D., van der Laan, G., Pigazo, F., Palomares, F. J., …Cebollada, A. Interface alloying effects in the magnetic properties of Fe nanoislands capped with different materials. Physical review B: Condensed matter and materials physics, 78(10), https://doi.org/10.1103/physrevb.78.104403

We show that Fe nanoislands capped with Al, Pd, and Pt protecting layers include an alloy at the interface with the capping layer, which explains the previously known capping layer dependence on the interparticle magnetic coupling. Vibrating sample m... Read More about Interface alloying effects in the magnetic properties of Fe nanoislands capped with different materials.

Advances in clustering and visualization of time series using GTM through time (2008)
Journal Article
(2008). Advances in clustering and visualization of time series using GTM through time. https://doi.org/10.1016/j.neunet.2008.05.013

Most of the existing research on multivariate time series concerns supervised forecasting problems. In comparison, little research has been devoted to their exploration through unsupervised clustering and visualization. In this paper, the capabilitie...

Intervertebral disc cells as competent phagocytes in vitro: implications for cell death in disc degeneration (2008)
Journal Article
(2008). Intervertebral disc cells as competent phagocytes in vitro: implications for cell death in disc degeneration. Arthritis Research and Therapy, R86 -?. https://doi.org/10.1186/ar2466

INTRODUCTION: Apoptosis has been reported to occur in the intervertebral disc. Elsewhere in the body, apoptotic cells are cleared from the system via phagocytosis by committed phagocytes such as macrophages, reducing the chance of subsequent inflamma...
