Freshwater Biology, Volume 70, Issue 10, October 2025.ABSTRACT 5α‐Cyprinol sulfate (CPS), a kairomone released by cyprinid fishes, induces diel vertical migration (DVM) in Daphnia and thus shapes ecosystem dynamics wherever both taxa co‐occur. Here, we provide the first in situ quantification of CPS turnover, revealing strong temporal variability in this chemical signal and its ecosystem‐wide consequences

Quantum Corrections for a Cosmological String Solution [PDF]
, 1994 We investigate quantum corrections for a cosmological solution of the string effective action. Starting point is a classical solution containing an antisymmetric tensor field, a dilaton and a modulus field which has singularities in the scalar fields. As

The Value Relevance of a Firm's Carbon Risk Profile
Abacus, Volume 61, Issue 3, Page 555-601, September 2025.The aim of this paper is to provide insights into the capital market's role in incentivizing firms to engage meaningfully in the transition to a net zero carbon emissions economy. We investigate whether capital markets negatively value a broader concept of carbon risk exposure in addition to its historic carbon footprint and offset assessed penalties ...

Exact Four-Dimensional Dyonic Black Holes and Bertotti-Robinson Spacetimes in String Theory
, 1994 Conformal field theories corresponding to two-dimensional electrically charged black holes and to two-dimensional anti-de Sitter space with a covariantly constant electric field are simply constructed as $SL(2,R)/Z$ WZW coset models.

Human Midbrain Organoids Enriched With Dopaminergic Neurons for Long‐Term Functional Evaluation
Cell Proliferation, Volume 58, Issue 7, July 2025.We optimised a protocol that combines developmental patterning with mechanical cut to produce pint‐sized midbrain organoids, with diameters less than 300 μm, suitable for long‐term evaluation, along with a comprehensive functional assay system consisting of calcium transient assay, neurite extension assay, and multielectrode array assay. ABSTRACT Human

Income distribution in a monetary economy
PSL Quarterly Review, 2014 In a monetary economy capital is a fund. This idea is captured by the circuit of capital. We define a circuit for fixed capital and argue that it is closed when the fund that initiates it is recovered in a present value sense.

Inhomogeneous Field Configurations and the Electroweak Phase Transition
, 1993 We investigate the effects of inhomogeneous scalar field configurations on the electroweak phase transition. For this purpose we calculate the leading perturbative correction to the wave function correction term $Z(\vph,T)$, i.e., the kinetic term in the
