During the pre-surgical evaluation of drug-resistant epilepsy, the assessment of the extent of the epileptogenic zone and its organization is a crucial objective. Indeed, the epileptogenic zone may be organized as a simple focal lesional site or as a more complex network (often referred to as the 'epileptogenic network') extending beyond the lesion. This distinction is particularly relevant in ...

The effects of cooling flow injection on the flow development and acoustic oscillation in a premixed swirl-stabilized combustor had been numerically investigated using 3D large-eddy simulation. Three different cases, including one with no injection and two with cooling flow injection (5, 20 m s), were simulated. With injection of cooling flow-through slits in the combustor wall, the absolute ve...

In this paper, we evaluate the strategy of using self-assembled microbeads to build a robust and tunable membrane for free-flow zone electrophoresis in a PDMS microfluidic chip. To fabricate a porous membrane as a salt bridge for free-flow zone electrophoresis, we used silica or polystyrene microbeads between 3-6 μm in diameter and packed them inside a microchannel. After complete evaporation, ...

Gradient-driven interactions and exchange mechanisms of the reed – open water interface in shallow lake environment were investigated by localised field measurements and detailed data analysis. High frequency 3D flow velocities were recorded in several points throughout a typical interface zone of Lake Fertő. Based on the data the flow distribution, specific discharge, energy dissipation rate, ...

An artificial pancreatic β-cell based on multipartite zone model predictive control (Multi-Zone-MPC) is evaluated on the UVa FDA-accepted metabolic simulator. Multi-Zone-MPC provides different tunings for the MPC weights based on four regions of glycemia: hypoglycemia, normoglycemia, elevated glycemia, and hyperglycemia. Defining these four zones provides richer control tunings that result in s...

سازند کژدمی (اواخر آپتین پیشین – آلبین میانی) یکی از سازند های شیلی مارنی است، که در زون ساختاری زاگرس در جنوب و جنوب غرب ایران قرار گرفته و این سازند بواسطه پتانسیل سنگ منشا بودن مخازن نفت وگاز سازند آسماری در اکثر میادین نفتی، یکی از مهم ترین سازند های زاگرس است. به منظور مطالعات زیست چینه ای و تعیین سن دقیق سازند کژدمی بر اساس فرامینیفرهای پلانکتونیک و تطابق بایوزون های شناسایی شده با بایوزو...

Prior investigations by the principal author evaluated the feasibility of mobilizing non-aqueous phase liquid (NAPL) ganglia by inducing vibrations in a soil-NAPL-water medium. In this paper, results from bench-scale experiments are reported to provide a practical understanding of the impact of vibrations (induced with a probe-type vibrator) on relative density of the medium and on the ganglia ...

We report a novel experimental technique that measures simultaneously in three dimensions the trajectories, the translation, and the rotation of finite size inertial particles together with the turbulent flow. The flow field is analyzed by tracking the temporal evolution of small fluorescent tracer particles. The inertial particles consist of a super-absorbent polymer that renders them index an...

Zero index materials where sound propagates without phase variation, holds a great potential for wavefront and dispersion engineering. Recently explored electromagnetic double zero index metamaterials consist of periodic scatterers whose refractive index is significantly larger than that of the surrounding medium. This requirement is fundamentally challenging for airborne acoustics because the ...

In the FIDA experiment, a pressure gradient generates the flow resulting in a parabolic flow profile. The parabolic flow profile inside the capillary distorts the indicator zone resulting in a concentration gradient between the center and the periphery of the capillary (figure S1). Equation 5 in the main manuscript is valid provided there is sufficient time for radial diffusion, and that advect...
