Constraints on CP violation in the Higgs sector from the $\rho$ parameter

open access: yes, 1993
We discuss the relation between the CP symmetry and the custodial $SU(2)$ symmetry in the Higgs sector. In particular, we show that CP violation in the Higgs-gauge sector is allowed only if the custodial $SU(2)$ symmetry is broken. We exploit these facts

The relativistic correction of the quarkonium melting temperature with a holographic potential

open access: yes, 2012
The relativistic correction of the AdS/CFT implied heavy quark potential is examined within the framework of the potential model. For the typical range of the coupling strength appropriate to heavy-ion collisions, we find the correction is significant in

Understanding Climate Change Education Practices in Kalimantan Through Exploratory Field Research With Local Voices

open access: yesScience Education, EarlyView.
ABSTRACT This article is based on a study that examines the practices and perspectives of selected educational actors in Kalimantan, Indonesia, on climate change education. The region is highly affected by climate crises and holds global relevance for mitigation due to its tropical forests and peatlands.

Condensation of a tetrahedra rigid-body libration mode in HoBaCo4O7 : the origin of phase transition at 355 K

open access: yes, 2009
Rietveld profiles, Moessbauer spectra and x-ray absorption fine structure (XAFS) were analyzed through the structural phase transition at Ts = 355 K in HoBaCo4O7. Excess of the oxygen content over O7 was avoided via annealing the samples in argon flow at

Using Cu2+‐Centered Complexes as Glue: Two New Layered Polyoxotantalates Based on the Interconnection of the {Ta6O19} Moiety

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Layered structures of polyoxotantalates generated by different connection modes of the dimeric {(Cu(dien))2Cu(Ta6O19)2} unit. Applying the three different solutions [Cu(dien)]2+ in DMSO/H2O, acetonitrile, and [Ta6O19]6‐/H2O in a layering approach, the two new polyxotantalates [Cu(dien)]5{(Cu(dien)(H2O)2)Cu(Ta6O19)2}·DMSO·32 H2O (I) and K2[(Cu(dien))6 ...

Machine Learning Model for an App‐Based Tool to Assist With the Diagnosis of Canine Atopic Dermatitis

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 236-246, April 2026.
Canine atopic dermatitis (cAD) is a chronic condition requiring life‐long management. Accurate diagnosis can be challenging, with no reliable diagnostic test. This study aimed to generate a simple diagnostic model for cAD. This model is a relevant prototype for an app‐based tool to support general practitioners in the diagnosis of cAD alongside ...
