Forensic electrochemistry: time since deposition (TSD) estimation of degrading bloodstains using differential pulse voltammetry
(2021-12-01)Methods for bloodstain time since deposition (TSD) estimation are still in development. Hemoglobin (Hb) oxidative changes remain one of the primary means of bloodstain aging. This research explores the use of differential ... -
Forward and reverse genetic approaches to investigate cellulose biosynthesis in Physcomitrium patens
(2021-04-01)Cellulose biosynthesis is a common feature of land plants and involves multimeric complexes composed of cellulose synthase A (CESA) proteins and other structural proteins. The exact stoichiometry of CESA proteins and ... -
Forward genetic analysis of cellulose biosynthesis inhibitor resistance and wall hydrolysis sensitivity.
(2014-09-01)The functional analysis of components involved in cellulose biosynthesis is central in understanding cell wall assembly and structure in plants. We conducted screens using the herbicides, isoxaben and flupoxam which inhibit ... -
Forward screening for herbicide resistance in Arabidopsis thaliana and the monocot species Triticum aestivum
(2019-06-01)Cellulose is the primary structural component of plant cell walls and is composed of β-1,4-glucan chains. The cellulose synthesis complex is composed of multiple cellulose synthases (CESAs), which work together to extend ... -
A Framework for Interactive Conference Posters
(2021-05-25)In this paper, we present a complete framework for extending conference posters with interactive content. Poster content will become interactive, allowing viewers to manipulate visualizations, and save them for later. We ... -
A framework for privacy-preserving data sharing in smart grid
(2016-01-01)While smart grid introduces a lot of enhancements to the traditional power grid and improves managing and controlling consumers demands, it also introduces security and privacy issues. Therefore, failure to address them ... -
A framework for video-driven crowd synthesis.
(2014-09-01)We present a framework for video-driven crowd synthesis. The proposed framework employs motion analysis techniques to extract inter-frame motion vectors from the exemplar crowd videos. Motion vectors collected over the ... -
Free methionine sulfoxide reductase and its contributions to environmental stress response in Komagataeibacter hansenii
(2023-12-01)Komagataeibacter hansenii (ATCC 23769) is a non-virulent acetic acid bacterium that forms cellulosic biofilms at the air-liquid interface of liquid media, serving as a model for biofilm forming pathogenic bacteria. In this ... -
The Functionalization of Magnetic Fe3O4@TiO2 by Molecular Motif for the Detection of Mercury (II)
(2019-07-01)2,6-bis(2-thienyl)pyridine (L) molecular receptor showed strong potential for Hg2+ detection. The chelation through S,N,S was confirmed as a main binding mode of the ligand with Hg2+ ion based on the results of 1H NMR. L ... -
