Rubisco in the Alpha-Carboxysome: from Structures to Binding Curves Open
In recent years, cryo-electron tomography has become increasingly popular as a method for in situ structural biology and biophysics over a wide range of resolutions, and structures solved through subtomogram averaging have allowed characte…
Oh, Jeez! or Uh-huh? A Listener-aware Backchannel Predictor on ASR Transcriptions Open
This paper presents our latest investigation on modeling backchannel in conversations. Motivated by a proactive backchanneling theory, we aim at developing a system which acts as a proactive listener by inserting backchannels, such as cont…
Estimating the heating of complex nanoparticle aggregates for magnetic hyperthermia Open
With application in magnetic hyperthermia treatment planning, this study shows that the heat released per particle under AC fields stagnates in clusters comprising 20 nanoparticles or more. This heat can be predicted using their fractal pa…
Heating of metallic biliary stents during magnetic hyperthermia of patients with pancreatic ductal adenocarcinoma: an <i>in silico</i> study Open
The safety of patients with pancreatic cancer wearing metallic biliary stents during magnetic hyperthermia treatments cannot be fully assured under the most common treatment parameters.
Estimating the heating of complex nanoparticle aggregates for magnetic hyperthermia Open
Understanding and predicting the heat released by magnetic nanoparticles is central to magnetic hyperthermia treatment planning. These nanoparticles tend to form aggregates when injected in living tissues, which alters their response to th…
