Variations of 14-C around AD 775 and AD 1795 - due to solar activity
, 2015 The motivation for our study is the disputed cause for the strong variation of 14-C around AD 775. Our method is to compare the 14-C variation around AD 775 with other periods of strong variability.

Self-assembly of carbon nanotubes and antibodies on tumours for targeted, amplified delivery
Nature Nanotechnology, 2013 Single-walled carbon nanotubes (SWNTs) can deliver imaging agents or drugs to tumours and offer significant advantages over approaches based on antibodies or other nanomaterials.

An FPGA Implementation of Convolutional Spiking Neural Networks for Radioisotope Identification [PDF]
arXiv, 2021 This paper details the FPGA implementation methodology for Convolutional Spiking Neural Networks (CSNN) and applies this methodology to low-power radioisotope identification using high-resolution data. Power consumption of 75 mW has been achieved on an FPGA implementation of a CSNN, with an inference accuracy of 90.62% on a synthetic dataset.

Who Pulled the Trigger: a Supernova or an AGB Star?
, 2010 The short-lived radioisotope $^{60}$Fe requires production in a core collapse supernova or AGB star immediately before its incorporation into the earliest solar system solids. Shock waves from a somewhat distant supernova, or a relatively nearby AGB star,

Cores of production : reactors and radioisotopes in France [PDF]
, 2009 This paper concerns the technologies used in radioisotope production in the French Atomic Energy Commission (the Commissariat à l'Energie Atomique) between 1946 and 1958.

Delayed X- and Gamma-Ray Line Emission from Solar Flare Radioactivity [PDF]
, 2006 We have studied the radioactive line emission expected from solar active regions after large flares, following the production of long-lived radioisotopes by nuclear interactions of flare-accelerated ions. This delayed X- and gamma-ray line emission can provide unique information on the accelerated particle composition and energy spectrum, as well as on

Methyl jasmonate elicits rapid changes in carbon and nitrogen dynamics in tomato.
New Phytologist, 2010 • Evidence is emerging to support the notion that in response to herbivory, plants undergo changes in their primary metabolism and are able to fine-tune the allocation of new and existing resources and temporarily direct them to storage organs.

Event-based Signal Processing for Radioisotope Identification [PDF]
arXiv, 2020 This paper identifies the problem of unnecessary high power overhead of the conventional frame-based radioisotope identification process and proposes an event-based signal processing process to address the problem established. It also presents the design flow of the neuromorphic processor.

, 2016 An oscillation with a period of about 2100-2500 years, the Hallstatt cycle, is found in cosmogenic radioisotopes (C-14 and Be-10) and in paleoclimate records throughout the Holocene. Herein we demonstrate the astronomical origin of this cycle.
