Dynamic calibration of agent-based models using data assimilation.

Royal Society open science

Ward JA, Evans AJ, Malleson NS.
PMID: 27152214
R Soc Open Sci. 2016 Apr 13;3(4):150703. doi: 10.1098/rsos.150703. eCollection 2016 Apr.

A widespread approach to investigating the dynamical behaviour of complex social systems is via agent-based models (ABMs). In this paper, we describe how such models can be dynamically calibrated using the ensemble Kalman filter (EnKF), a standard method of...

Since its beginning, more than 117 years ago, the compression-ignition engine, or diesel engine, has grown to become a critically important part of industry and transportation. Public concerns over the health effects from diesel emissions have driven the growth...

Fluorescence spectroscopy and microscopy as tools for monitoring redox transformations of uranium in biological systems.

Chemical science

Jones DL, Andrews MB, Swinburne AN, Botchway SW, Ward AD, Lloyd JR, Natrajan LS.
PMID: 29142731
Chem Sci. 2015 Sep 01;6(9):5133-5138. doi: 10.1039/c5sc00661a. Epub 2015 Jun 09.

We report a study of redox reactions of uranium in model conditions using luminescence spectroscopy, which with its ease and wide availability has the potential to offer new insights into a bioremediation strategy of particular interest - the enzymatic...

An examination of the factors influencing mercury and methylmercury particulate distributions, methylation and demethylation rates in laboratory-generated marine snow.

Marine chemistry

Ortiz VL, Mason RP, Ward JE.
PMID: 26644635
Mar Chem. 2015 Dec 20;177:753-762. doi: 10.1016/j.marchem.2015.07.006.

In the marine environment, settling particulates have been widely studied for their role as effective vertical transporters of nutrients and metals scavenged from the euphotic zone to the benthos. These particulates are composed of transparent exopolymers, plankton and bacterial...

Synthesis and characterization of two quaternary uranium tellurides, RbTiU₃Te₉ and CsTiU₃Te₉.

Inorganic chemistry

Ward MD, Mesbah A, Lee M, Malliakas CD, Choi ES, Ibers JA.

Inorg Chem. 2014 Aug 04;53(15):7909-15. doi: 10.1021/ic500599d. Epub 2014 Jul 22.

Black crystals of RbTiU₃Te₉ and CsTiU₃Te₉ have been synthesized at 1223 and 1173 K, respectively, by high-temperature solid-state routes. These compounds crystallize in a new structure type in space group C(2h)²-P2₁/m of the monoclinic system. The structure, which is...

Measurement of mercury species in human blood using triple spike isotope dilution with SPME-GC-ICP-DRC-MS.

Analytical and bioanalytical chemistry

Sommer YL, Verdon CP, Fresquez MR, Ward CD, Wood EB, Pan Y, Caldwell KL, Jones RL.
PMID: 24948088
Anal Bioanal Chem. 2014 Aug;406(20):5039-47. doi: 10.1007/s00216-014-7907-4. Epub 2014 Jun 20.

The measurement of different mercury compounds in human blood can provide valuable information about the type of mercury exposure. To this end, our laboratory developed a biomonitoring method for the quantification of inorganic (iHg), methyl (MeHg), and ethyl (EtHg)...

Perceived discrimination and depressive symptoms among US Latinos: the modifying role of educational attainment.

Ethnicity & health

Ward JB, Feinstein L, Vines AI, Robinson WR, Haan MN, Aiello AE.
PMID: 28399649
Ethn Health. 2019 Apr;24(3):271-286. doi: 10.1080/13557858.2017.1315378. Epub 2017 Apr 12.

OBJECTIVE: Despite growing evidence that discrimination may contribute to poor mental health, few studies have assessed this association among US Latinos. Furthermore, the interaction between discrimination and educational attainment in shaping Latino mental health is virtually unexplored. This study...

'One-stop shop': lung cancer patients' and caregivers' perceptions of multidisciplinary care in a community healthcare setting.

Translational lung cancer research

Kedia SK, Ward KD, Digney SA, Jackson BM, Nellum AL, McHugh L, Roark KS, Osborne OT, Crossley FJ, Faris N, Osarogiagbon RU.

The cephalopod genus Nautilus is considered a "living fossil" with a contested number of extant and extinct species, and a benthic lifestyle that limits movement of animals between isolated seamounts and landmasses in the Indo-Pacific. Nautiluses are fished for...

Stepwise assembly of mixed-metal coordination cages containing both kinetically inert and kinetically labile metal ions: introduction of metal-centred redox and photophysical activity at specific sites.
