Quantum physics meets biology [PDF]

open access: yesHFSP Journal, 2009
Quantum physics and biology have long been regarded as unrelated disciplines, describing nature at the inanimate microlevel on the one hand and living species on the other hand. Over the last decades the life sciences have succeeded in providing ever more and refined explanations of macroscopic phenomena that were based on an improved understanding of ...

Characterization of a prototype rapid kilovoltage x‐ray image guidance system designed for a linear accelerator radiation therapy unit

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study evaluates a novel cone‐beam computed tomography (CBCT) imaging solution integrated onto a conventional C‐arm linear accelerator (linac) with increased gantry speed. The purpose is to assess the impact of improved imaging hardware and reconstruction algorithms on image quality.

Evaluating auto‐contouring accuracy in reduced CT dose images for radiopharmaceutical therapies: Denoising and evaluation of 177Lu DOTATATE therapy dataset

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Reducing radiation dose attributed to computed tomography (CT) may compromise the accuracy of organ segmentation, an important step in 177Lu DOTATATE therapy that affects both activity and mass estimates. This study aimed to facilitate CT dose reduction using deep learning methods for patients undergoing serial single photon emission ...

From Cbits to Qbits: Teaching computer scientists quantum mechanics [PDF]

open access: yes, 2002
A strategy is suggested for teaching mathematically literate students, with no background in physics, just enough quantum mechanics for them to understand and develop algorithms in quantum computation and quantum information theory.

Splits in students’ beliefs about learning classical and quantum physics

open access: yesInternational Journal of STEM Education, 2019
Background While there has been increasing recognition of the importance of attending to students’ views about what counts as knowing and learning a STEM field, surveys that measure these “epistemological” beliefs are often used in ways that implicitly ...

Determining spin-orbit coupling in graphene by quasiparticle interference imaging

open access: yesNature Communications, 2023
Inducing and controlling spin-orbit coupling (SOC) in graphene is key to create topological states of matter, and for the realization of spintronic devices. Placing graphene onto a transition metal dichalcogenide is currently the most successful strategy
