This paper addresses the growing challenge of AI data center expansion, specifically the constraints imposed by electricity and cooling capacity. It proposes an innovative solution by integrating Waste-to-Energy (WtE) with AI data centers, treating cooling as a core energy service. The study's significance lies in its focus on thermoeconomic optimization, providing a framework for assessing the feasibility of WtE-AIDC coupling in urban environments, especially under grid stress. The paper's value is in its practical application, offering siting-ready feasibility conditions and a computable prototype for evaluating the Levelized Cost of Computing (LCOC) and ESG valuation.

The central mechanism is energy-grade matching: low-grade WtE thermal output drives absorption cooling to deliver chilled service, thereby displacing baseline cooling electricity.

Analysis

This paper investigates the Sommerfeld enhancement mechanism in dark matter annihilation as a possible explanation for the observed gamma-ray excess in the Milky Way halo. It proposes a model with a light scalar mediator that can reconcile the observed excess with constraints from other observations like dwarf spheroidal galaxies. The work is significant because it explores a specific particle physics model to address a potential dark matter signal.
Reference

A minimal model with a light CP-even scalar mediator naturally produces a velocity-dependent annihilation cross section consistent with thermal freeze-out, the Milky Way excess, and limits from dwarf spheroidal galaxies.

Analysis

This paper offers a novel axiomatic approach to thermodynamics, building it from information-theoretic principles. It's significant because it provides a new perspective on fundamental thermodynamic concepts like temperature, pressure, and entropy production, potentially offering a more general and flexible framework. The use of information volume and path-space KL divergence is particularly interesting, as it moves away from traditional geometric volume and local detailed balance assumptions.
Reference

Temperature, chemical potential, and pressure arise as conjugate variables of a single information-theoretic functional.
