Radial Interaction Tomography: Recognizing Non-Transitive Evolutionary Games from One Range-Expansion Image
Faruk Alpay, Baris Basaran
Colored sectors in a microbial range expansion encode more than lineage survival counts. We formulate a computer-vision inverse problem: from one endpoint image of an accretive mul…
Interface-Variant Dynamics in Software Ecosystems: Resolver-Induced Selection and Adoption in Package Graphs
Faruk Alpay, Baris Basaran
Compatibility research usually treats an interface change as a local writer-reader decision. Distributed software stacks make that decision population structured: an RPC, telemetry…
Detector-Output Instability near the Kesten-Stigum Boundary: Separating Hard Readout, Relaxation, and Fixed-Point Dispersion
Faruk Alpay, Baris Basaran
Community-detection algorithms usually return a single partition, even when independent initializations or small data perturbations yield several plausible outputs. We probe this o…
Dipole Diffusion Error in Thin Geometry: Optical Thickness Laws for Grid-Free Subsurface Scattering
Faruk Alpay, Baris Basaran
The dipole and its descendants model subsurface scattering with a radial reflectance profile fitted to a flat, semi-infinite slab. This assumption introduces a systematic geometry…
Self-Verifying Measurement Records: Hash-Linked Evidence Graphs for Hardware Benchmarking
Faruk Alpay, Baris Basaran
Performance numbers reported for hardware are accepted on trust: the reader cannot recompute them, the apparatus is gone, and the silicon itself can be silently wrong, with fleet s…
Residual GPU Cache State on Apple M4 Pro
Faruk Alpay, Baris Basaran
Apple silicon exposes unified CPU-GPU memory, but the cache state left after a completed GPU command is not documented. This paper characterizes that phase boundary on a 14-core Ap…
