Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm. [PDF]

Appl Plant Sci
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Aging and longevity in decades-old genebanked seeds from U.S. endangered plant species: Assessments using survival and RNA integrity assays. [PDF]

Am J Bot
Abstract Premise Seed longevity is critical for successful genebanking, but it is hard to detect or predict. We examined survival of genebanked seeds from species native to the United States to estimate longevity. We tested whether RNA integrity (RIN) can be used to detect aging and predict mortality. Methods Dry seeds from >100 species were stored for

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects. [PDF]

Insect Sci
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

Microtubule-affinity regulating kinase family members distinctively affect tau phosphorylation and promote its toxicity in a Drosophila model. [PDF]

Genes Cells
Members of the Microtubule Affinity Regulating Kinase family (MARK1‐4) phosphorylate tau at microtubule‐binding repeats and are considered potential therapeutic targets for AD. We analyzed how each member of the MARK family affects tau phosphorylation and toxicity in a Drosophila model.

In Situ (Operando) Electrochemical Dilatometry as a Method to Distinguish Charge Storage Mechanisms and Metal Plating Processes for Sodium and Lithium Ions in Hard Carbon Battery Electrodes

Advanced Materials Interfaces, Volume 9, Issue 8, March 11, 2022., 2022
Plating only for sodium: The storage mechanism of sodium and lithium ions in hard carbon is investigated by monitoring the change of the electrode thickness during charging and discharging. For lithium ions, a two‐step mechanism is found, whereas for sodium ions, a three‐step mechanism with a plating process as the last mechanism is found.

Curvature Effect in Shear Flow: Slowdown of Turbulent Flame Speeds with Markstein Number

Communications in Mathematical Physics, 2017
It is well known in the combustion community that curvature effect in general slows down flame propagation speeds because it smooths out wrinkled flames. However, such a folklore has never been justified rigorously. In this paper, as the first theoretical result in this direction, we prove that the turbulent flame speed (an effective burning velocity ...

Flame propagation in arbitrarily shaped vessels

Proceedings in Applied Mathematics and Mechanics, Volume 18, Issue 1, December 2018., 2018
Abstract A new method to capture the flame front in premixed, confined, low Mach number combustion using the flame‐sheet approximation is presented. Connected marker points represent the flame front along which a singular volumetric flux source is prescribed. Thus, the jump condition for the normal velocity is fulfilled.

Equivolumetric Evolution of Planar Curves

Abstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014
We present the equivolumetric evolution of planar curves, which is a new type of curvature dependent evolution for a flame propagation model. This evolution reflects the nonlinear contribution of the curvature of the front to the flame propagation speed. We also present some numerical results of the equivolumetric evolution using the level set method.
