Grasstree stem analysis reveals insufficient data for inference of fire history
Grinding back dead leaf bases on the stems of arborescent grasstrees (Xant7wrrlwea spp.) reveals a pattern of horizontal bands that has been interpreted as a record of the fire history experienced by the plant. The validity of this fire history record has previously been assessed through comparison of 100 grasstree stems sampled from shrubland near Eneabba in Western Australia against a 30 year fire history determined from satellite imagery. This analysis showed that the two records matched more than would be expected by chance, but concluded that the interpretation of the grasstree record as a fire history was not warranted as most of the grasstree fire records did not match satellite fire records. A second analysis of the same two sets of records, published in this journal, also showed that the records matched more than by chance, but concluded that the interpretation of grasstree banding as fire history was valid, though it failed to quantify the strength of this agreement. Here we examine' the approaches and interpretations of the two previously published studies, and provide new analyses to refine estimates of the amount of fire-related data present in the grasstree record. We show that only ~20% of grasstree 'fire' records may be attributable to fire. With eight out of ten of records not attributable to fire, we confirm that the grasstree record in its current form cannot be interpreted as fire history, and therefore claims of the grasstree technique to support management actions are untenable

Discovery and validation of blood microRNAs as molecular biomarkers of epilepsy: Ways to close current knowledge gaps
There is a major unmet need for biomarkers of epilepsy. Biofluids such as blood offer a potential source of molecular biomarkers. MicroRNAs (miRNAs) fulfill several key requirements for a blood-based molecular biomarker being enriched in the brain and dysregulated in epileptic brain tissue, and manipulation of miRNAs can have seizure-suppressive and disease-modifying effects in preclinical models. Biofluid miRNAs also possess qualities that are favorable for translation, including stability and easy and cheap assay techniques. Herein we review findings from both clinical and animal models. Studies have featured a mix of unbiased profiling and hypothesis-driven efforts. Blood levels of several brain-enriched miRNAs are altered in patients with epilepsy and in patients with drug-resistant compared to drug-responsive seizures, with encouraging receiver-operating characteristic (ROC) curve analyses, both in terms of sensitivity and specificity. Both focal and generalized epilepsies are associated with altered blood miRNA profiles, and associations with clinical parameters including seizure burden have been reported. Results remain preliminary, however. There is a need for continued discovery and validation efforts that include multicenter studies and attention to study design, sample collection methodology, and quality control. Studies focused on epileptogenesis as well as associations with covariables such as sex, etiology, and timing of sampling remain limited. We identify 10 knowledge gaps and propose experiments to close these. If adequately addressed, biofluid miRNAs may be an important future source of diagnostic biomarkers that could also support forthcoming trials of antiepileptogenesis or disease-modifying therapies
A Scattered Data Interpolant for the Solution of Three-Dimensional PDEs
Using a Differential Equation Interpolant (DEI), one can accurately approximate the solution of a Partial Differential Equation (PDE) at off-mesh points. The idea is to allocate a multi-variate polynomial to each mesh element and consequently, the collection of such polynomials over all mesh elements will define a piecewise polynomial approximation. In this paper we will investigate such interpolants on a three-dimensional unstructured mesh. As reported by Enright, for a tetrahedron mesh in three dimensions, tensor product tri-quadratic and pure tri-cubic interpolants are the most appropriate candidates. We will report on the effectiveness of these alternatives on some typical PDEs

All three methods, Autocorrelation, Enright and DFT predict approximately 1.17 minute periods in islet Ca<sup>2+</sup> oscillations.
<p>(A) 30 minutes of oscillatory data representing Ca<sup>2+</sup> oscillations; (B) Autocorrelation periodogram generated with the Autocorrelation method. The plot shows 5 significant local maxima obtained at the significance level of 0.01; (C) Enright periodogram generated by the Enright method. The plot shows 1 significant and 4 non significant local maxima obtained at the significance level of 0.01; (D) Frequency spectrum generated with the DFT method. The plot shows 3 significant and 2 non significant oscillatory periods obtained at the significance level of 0.01. Closed circles represent significant periods. Open circles represent non significant periods. We selected a maximum of five oscillatory candidate periods in each method. The candidates were ordered by the value of its period in the Autocorrelation and Enright methods, and by power in the DFT method.</p
