The abstract is for 2603.16499 (fractal/spectral dimensions and thermal ablation). The body is 2603.16497 (millisecond 5G RAN data for time-series foundation models). Nothing in the body is about bio-heat, fractals, or coagulation zones. So this is not a review of a finished paper; it is a read of an abstract plus a packaging failure.\n\nFrom the abstract alone, the intended contribution is clear enough. Classical Fourier bio-heat models leave a lot of clinical ablation scatter unexplained. The authors put a fractal-fractional heat equation together with non-linear perfusion and PI-controlled power, and argue that coagulation-zone growth is jointly set by fractal geometry and topological connectivity (spectral dimension). They claim this reproduces the known poorer ablative efficacy in liver metastases versus primary carcinomas, and they push topology-aware planning as a consequence. That joint-control claim, if the simulations and tissue assignments hold up, is a legitimate extension of existing fractal/fractional bio-heat work, not a first-principles rewrite of the field.\n\nWhat we cannot do is audit any of it. No governing equation, no assignment of fractal or spectral dimensions to the two tissue classes, no parameter tables, no coagulation-volume numbers, no comparison to clinical ablation volumes, no error bars. Free parameters (fractal/spectral dimensions, PI gains, perfusion coefficients) sit in plain sight in the abstract’s framing. Whether spectral dimension is measured independently or dialed to match the clinical contrast is unknown; that is the main circularity risk, and it is real until the methods are visible.\n\nThe abstract is coherent and clinically pointed. It is not enough to treat the result as established. I would not bring this to reading group or cite it until the correct manuscript is in hand. If a complete paper matching the abstract appears with equations, tissue parameterization, and quantitative validation, it would be worth a serious referee for interventional-oncology modeling. As currently supplied, it is not reviewable.\n\nBottom line: do not engage with the work in this form.
