Towards implementing multi-channels, ring-oscillator-based, Vernier time-to-digital converter in FPGAs: key design points and construction method [PDF]
, 2017 For TOF positron emission tomography (TOF PET) detectors, time-to-digital converters (TDCs) are essential to resolve the coincidence time of the photon pairs. Recently, an efficient TDC structure called ring-oscillator-based (RO-based) Vernier TDC using carry chains was reported by our team.

Are wave union methods still suitable for 20 nm FPGA-based high-resolution (< 2 ps) time-to-digital converters? [PDF]
arXiv, 2020 This paper presents several new structures to pursue high-resolution (< 2 ps) time-to-digital converters (TDCs) in Xilinx 20 nm UltraScale field-programmable gate arrays (FPGAs). The proposed TDCs combined the advantages of 1) our newly proposed sub-tapped delay line (sub-TDL) architecture effective in removing bubbles and zero-bins and 2) the wave ...

Frontiers in Psychology, 2014 Neuroplasticity, and functional connectivity are important physiological derivates of cognition, and behaviour. Recently introduced non-invasive brain stimulation techniques are suited to induce, and modulate respective physiological alterations. One of these techniques is transcranial direct current stimulation (tDCS).

35Cl NMR of Metal‐Organic Frameworks: What Can We Learn?
Chemistry–Methods, EarlyView.35Cl solid‐state NMR of MOFs offers insights into bonding mode and character, hydrogen bonding, phase transitions, and reaction products, even near paramagnetic centers. 35Cl NMR parameters reflect Cl coordination and local geometry. DFT methods accurately predict 35Cl NMR parameters. This 35Cl NMR/DFT approach is applicable to other MOFs and materials.
