Stochastic Arithmetic as a Tool to Study the Stability of Biological Models

open access: yesBiomath, 2014
The theoretical study of the stability of the numerical solution of a differential system may be complicated or even not feasible when the system is large and nonlinear.

A hardware architecture for numerical instability detection based on discrete stochastic arithmetic [PDF]

open access: yes, 2011
Numerical validation of computed results is of great importance especially in sceintific computing. Due to the use of finite representation of real numbers, round-off errors are introduced and accumulated in arithmetic operations. Nowadays, softwares tend to run longer. This exaggerate the problem as the computed results would get severely contaminated

Optimal execution strategy in liquidity framework

open access: yesCogent Economics & Finance, 2017
A trader wishes to execute a given number of shares of an illiquid asset. Since the asset price also depends on the trading behaviour, the trader main aim is to find the execution strategy that minimizes the related expected costs.

People Counting and Positioning Using Low‐Resolution Infrared Images for FeFET‐Based In‐Memory Computing

open access: yesAdvanced Electronic Materials, EarlyView.
In this work, low‐resolution infrared imaging is combined with a 28 nm FeFET IMC architecture to enable compact, energy‐efficient edge inference. MLC FeFET devices are experimentally characterized, and controlled multi‐level current accumulation is validated at crossbar array level.

SigmaFormer: Augmenting transformer encoders with COSMO sigma profiles for pure component property prediction

open access: yesAIChE Journal, EarlyView.
Abstract Transformer‐based molecular models pretrained on SMILES strings demonstrate strong performance in property prediction. However, these model often lack explicit integration of molecular surface charge distributions that govern intermolecular interactions such as hydrogen bonding and polarity.

Calibration‐Free Electromyography Motor Intent Decoding Using Large‐Scale Supervised Pretraining

open access: yesAdvanced Intelligent Systems, EarlyView.
Calibration‐free electromyography motor intent decoding is enabled through large‐scale supervised pretraining across heterogeneous datasets. A Spatially Aware Feature‐learning Transformer processes variable channel counts and electrode geometries, allowing transfer across users and recording setups. On a held‐out benchmark, fine‐tuned cross‐user models
