Two-nucleon scattering: merging chiral effective field theory with dispersion relations [PDF]
, 2013 We consider two-nucleon scattering close to threshold. Partial-wave amplitudes are obtained by an analytic extrapolation of subthreshold reaction amplitudes calculated in a relativistic formulation of chiral perturbation theory.

Analysis of the subthreshold current of pocket or halo-implanted nMOSFETs [PDF]
, 2006 In this work, we analyzed the subthreshold current (I/sub D/) of pocket implanted MOSFETs using extensive device simulations and experimental data. We present an analytical model for the subthreshold current applicable for any type of FET and show that ...

BIOPHYSICAL PROPERTIES OF SUBTHRESHOLD RESONANCE OSCILLATIONS AND SUBTHRESHOLD MEMBRANE OSCILLATIONS IN NEURONS [PDF]
Journal of Biological Systems, 2016 Subthreshold-level activities in neurons play a crucial role in neuronal oscillations. These small-amplitude oscillations have been suggested to be involved in synaptic plasticity and in determining the frequency of network oscillations. Subthreshold membrane oscillations (STOs) and subthreshold resonance oscillations (SROs) are the main constituents ...

Hardened Flip-Flop Optimized for Subthreshold Operation Heavy Ion Characterization of a Radiation
Journal of Low Power Electronics and Applications, 2012 A novel Single Event Upset (SEU) tolerant flip-flop design is proposed, which is well suited for very-low power electronics that operate in subthreshold ( < <em>Vt</em> ≈ 500 mV).

An Ultra-Low Energy Subthreshold SRAM Bitcell for Energy Constrained Biomedical Applications
Journal of Low Power Electronics and Applications, 2014 Energy consumption is a key issue in portable biomedical devices that require uninterrupted biomedical data processing. As the battery life is critical for the user, these devices impose stringent energy constraints on SRAMs and other system on chip (SoC)

Reconciling threshold and subthreshold expansions for pion-nucleon scattering [PDF]
, 2017 Heavy-baryon chiral perturbation theory (ChPT) at one loop fails in relating the pion-nucleon amplitude in the physical region and for subthreshold kinematics due to loop effects enhanced by large low-energy constants.

International Psychiatry, 2011 Are we in need of including in our diagnostic systems a new category of subthreshold psychiatry? Studies have shown that we are faced in our daily clinical practice with many patients who do not fulfil the criteria of either ICD-10 or DSM-IV (at best they may be included under 'atypical', 'unspecified' or 'not elsewhere classified'). Subthreshold cases

Frontiers in Cellular Neuroscience, 2019 Analog signaling describes the use of graded voltage changes as signals in the axonal compartment. Analog signaling has been described originally in invertebrates but more recent work has established its presence in the mammalian brain (Alle and Geiger ...

Subthreshold depression in Parkinson's disease [PDF]
International Journal of Geriatric Psychiatry, 2009 AbstractObjectiveIt is estimated that 40% of patients with Parkinson's disease (PD) are clinically depressed, however, little is known about the frequency and associated features of subthreshold depression in PD. The current study sought to determine the prevalence of subthreshold depression (sD) and to further characterize the associated features in a
