Radiative damping and electron beam dynamics in plasma-based accelerators.

Physical review. E, Statistical, nonlinear, and soft matter physics

Michel P, Schroeder CB, Shadwick BA, Esarey E, Leemans WP.
PMID: 17025550
Phys Rev E Stat Nonlin Soft Matter Phys. 2006 Aug;74(2):026501. doi: 10.1103/PhysRevE.74.026501. Epub 2006 Aug 15.

The effects of radiation reaction on electron beam dynamics are studied in the context of plasma-based accelerators. Electrons accelerated in a plasma channel undergo transverse betatron oscillations due to strong focusing forces. These oscillations lead to emission by the...

Hamiltonian description of low-temperature relativistic plasmas.

Physical review letters

Shadwick BA, Tarkenton GM, Esarey EH.
PMID: 15525084
Phys Rev Lett. 2004 Oct 22;93(17):175002. doi: 10.1103/PhysRevLett.93.175002. Epub 2004 Oct 18.

We develop a low-temperature fluidlike plasma model without recourse to a collisional closure. The equations are closed by treating the momentum spread asymptotically. This model inherits the Hamiltonian structure, including Casimir invariants of the Vlasov-Maxwell theory. We study temperature...

Epigenetics and personalized medicine: prospects and ethical issues.

Personalized medicine

Chadwick R, O'Connor A.
PMID: 29758832
Per Med. 2013 Jul;10(5):463-471. doi: 10.2217/pme.13.35.

As scientific knowledge about gene-environment interactions and the role of epigenetic factors in gene expression grows, new possibilities for personalized medicine may be opened up. In particular, the associations that have been demonstrated between epigenetic markers and certain diseases...

Ethics and regulatory considerations for the clinical translation of somatic cell human epigenetic editing.

Stem cell reports

Zeps N, Lysaght T, Chadwick R, Erler A, Foo R, Giordano S, San Lai P, Schaefer GO, Xafis V, Chew WL, Sugarman J.
PMID: 34214486
Stem Cell Reports. 2021 Jul 13;16(7):1652-1655. doi: 10.1016/j.stemcr.2021.06.004. Epub 2021 Jul 01.

Altering the human epigenome with gene-editing technology in attempt to treat a variety of diseases and conditions seems scientifically feasible. We explore some of the ethical and regulatory issues related to the clinical translation of human epigenetic editing arguing...

A new method of contrast enhancement of musculoskeletal ultrasound imaging based on fuzzy inference technique.

Biomedical physics & engineering express

Jabbar SI, Aladi AQ, Day C, Chadwick E.
PMID: 34161931
Biomed Phys Eng Express. 2021 Jul 07;7(5). doi: 10.1088/2057-1976/ac0dce.

Improving the clarity and visual quality of Musculoskeletal Ultrasound Images (MUI) can help clinicians to detect diseases more easily and accurately. In this work, we described how to enhance the contrast of MUI locally based on a fuzzy inference...

The comments of voices on the appearance of patients with psychosis: 'the voices tell me that I am ugly'.

BJPsych open

Waite F, Diamond R, Collett N, Chadwick E, Bold E, Teale AL, Taylor KM, Kirkham M, Twivy E, Causier C, Carr L, Bird JC, Černis E, Isham L, Freeman D.
PMID: 31537204
BJPsych Open. 2019 Sep 20;5(5):e86. doi: 10.1192/bjo.2019.66.

BACKGROUND: There are high rates of obesity and low self-esteem in patients with psychosis. The occurrence of negative voice content directly about appearance is therefore plausible. Derogatory comments about appearance are likely to be distressing, increase depression and contribute...

Approaches for deep-ultraviolet surface plasmon resonance sensors.

Optics letters

Moreira C, Wang Y, Blair S, Chadwick E, Lee JY, Oliveira L, Lima A, Cruz R.
PMID: 32797030
Opt Lett. 2020 Aug 15;45(16):4642-4645. doi: 10.1364/OL.397641.

Aluminum (Al) is a preferred metal for designing deep-ultraviolet (DUV) surface plasmon resonance (SPR)-based sensors. The native oxide layer (alumina), which grows when the Al film is exposed to air, adds an extra layer to the multilayer stack and...

An international Delphi consensus for pelvic stereotactic ablative radiotherapy re-irradiation.

INTRODUCTION: Stereotactic Ablative Radiotherapy (SABR) is increasingly used to treat metastatic oligorecurrence and locoregional recurrences but limited evidence/guidance exists in the setting of pelvic re-irradiation. An international Delphi study was performed to develop statements to guide practice regarding patient...
