Scaling laws of Stablecoin Transactions: Evidence from USDT and USDC on the Ethereum blockchain

Kundan Mukhia, Sabat Rai, Vivek Shrivastav +2

Stablecoins have rapidly emerged as an important class of digital assets and a component of the digital financial ecosystem. Despite their growing importance, the statistical prope…

Ion Channel Dynamics in Temperature-Dependent Weibel Instability Saturation

Vivek Shrivastav, Mani K Chettri, Hemam D. Singh +2

We present 1X2V continuum Vlasov-Maxwell simulations of interpenetrating plasma beams with mobile ions. While the early-time evolution is similar to the stationary-ion case, the la…

Linear-wave bound on electromagnetic energy equipartition at sub-electron scales in non-relativistic plasmas

Vivek Shrivastav, Mani K Chettri, Britan Singh +2

Recent Magnetospheric Multiscale (MMS) observations report approximate equality between electric and magnetic field energy spectral densities, $\varepsilon_{0} P[δE]/2 \approx P[΅

Inertial-Range Suppression and Ponderomotive Density Cavitation in Broadband Sub-Alfvénic Turbulence under Plasma Sheet Boundary Layer Conditions

Mani K Chettri, Vivek Shrivastav, Britan Singh +2

Kinetic Alfvén waves (KAWs) are among the most pervasive electromagnetic fluctuations in magnetized astrophysical plasmas, from Earth's magnetosphere to galaxy clusters. Their pon…

Weibel Instability in Collisionless Plasmas Across Astrophysical and Laboratory Shocks

Vivek Shrivastav, Mani K Chettri, Hemam D Singh +2

We present a cold-fluid analysis of the purely transverse Weibel (current-filamentation) instability across four regimes: non-relativistic (NR) single-species, NR multi-species, re…

State-of-the-art Small Language Coder Model: Mify-Coder

Abhinav Parmar, Abhisek Panigrahi, Abhishek Kumar Dwivedi +93

We present Mify-Coder, a 2.5B-parameter code model trained on 4.2T tokens using a compute-optimal strategy built on the Mify-2.5B foundation model. Mify-Coder achieves comparable a…
