The Social Truth of Schopenhauer's ‘Metaphysics of Pity’: Compassion and Critical Theory

open access: yesEuropean Journal of Philosophy, Volume 34, Issue 1, Page 79-95, March 2026.
Abstract Taking Horkheimer and Adorno's account of pity in the Dialectic of Enlightenment as my starting point, I show that Schopenhauer's compassion‐based moral theory exemplifies key elements of this account. In particular, this moral theory will be shown to possess a social truth for Horkheimer and Adorno because it is an expression of a wrong ...

Modified Central Difference Method for Negative Stiffness SDoF System Under Ground Seismic Excitation

open access: yesThe Structural Design of Tall and Special Buildings, Volume 35, Issue 2, February 2026.
ABSTRACT The present paper deals with the analytical and numerical solution of the motion equation of a single degree of freedom (SDoF) oscillator with damping and negative stiffness (NS) due to seismic excitation at its base. The resulting solution shows that the structure's response displacement increases exponentially; thus, practically, there is no

An Extension of a Formula of F. S. Rofe-Beketov

open access: yesMathematics
We address the following problem in this study: given a nontrivial solution, y1, of a four-coefficient Sturm–Liouville eigenvalue differential equation, construct a second solution, y2, linearly independent of y1.

Vortex Line Density in a Superfluid Turbulent Wake in the Zero Temperature Limit

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
The quasiclassical conjecture for quantum turbulence in a pure superfluid straightforwardly leads to the definition of the superfluid Reynolds number, Res=ud/κ$Re_s=ud/\kappa$, and suggests that the effective quantum viscosity should be of the order of the circulation quantum κ$\kappa$.

Data Driven Based Bridge Damage Identification Using a Statistical Approach Utilizing Vehicle‐Induced Acceleration Responses

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
The integration of data‐driven methodologies in bridge health monitoring is gaining increasing attention due to their ability to overcome conventional approaches’ limitations. This study proposes a bridge damage identification method for simply supported bridges, leveraging output‐only vehicle‐induced vibration responses, eliminating the need for ...

Research on a Rapid and Portable Measurement Method of Oil Density Based on Asynchronous Free Resonance

open access: yesJournal of Sensors, Volume 2026, Issue 1, 2026.
In response to the demand for rapid and portable measurement of oil density, this article establishes a full‐period vibration model including the transient excitation stage and the free attenuation stage based on the fluid inertia effect and viscous dissipation effect.
