Optical study of the vibrational and dielectric properties of BiMnO3

open access: yes, 2015
BiMnO3 (BMO), ferromagnetic (FM) below Tc = 100 K, was believed to be also ferroelectric (FE) due to a non-centro-symmetric C2 structure, until diffraction data indicated that its space group is the centro-symmetric C2/c.

Universal Teichmüller space and BMO

open access: yesAdvances in Mathematics, 2013
In the BMO theory of the universal Teichmüller space, some characterizations of the BMOA-Teichmüller space are well known. The authors give two more equivalent characterizations by using some kernel functions and corresponding operators induced by quasisymmetric homeomorphisms. Various equivalent characterizations of the VMOA-Teichmüller space are also

Evaluation of Precipitation Observations Across Ecuador

open access: yesAtmospheric Science Letters, Volume 27, Issue 1, January 2026.
This study aims to evaluate the performance of three precipitation products—ERA5 reanalysis, IMERG (Integrated Multi‐satellite Retrievals for GPM), and MSWEP (Multi‐Source Weighted‐Ensemble Precipitation)—across Ecuador's diverse climates and terrains.

Group B streptococcal sacroiliitis following an uncomplicated vaginal delivery: A case report and review of the literature

open access: yesPregnancy, Volume 2, Issue 1, January 2026.
Abstract Background Pregnant and postpartum patients are at risk of infectious sacroiliitis due to the increased demand on the sacroiliac joint as well as the changes in the pelvis during pregnancy and delivery. Case We present the case of a 34‐year‐old woman who developed severe back pain following an uncomplicated vaginal delivery and was ultimately ...

FLOW WITH $A_{\infty }(\mathbb{R})$ DENSITY AND TRANSPORT EQUATION IN $\text{BMO}(\mathbb{R})$

open access: yesForum of Mathematics, Sigma, 2019
We show that, if $b\in L^{1}(0,T;L_{\operatorname{loc}}^{1}(\mathbb{R}))$ has a spatial derivative in the John–Nirenberg space $\operatorname{BMO}(\mathbb{R})$, then it generates a unique flow $\unicode[STIX]{x1D719}(t,\cdot )$ which has an $A_{\infty }(\

Restricted Beurling transforms on Campanato spaces

open access: yes, 2016
Let $\Omega\subset \mathbb{C}$ be a bounded domain with $\mathcal{C}^{1,\omega}$-smooth boundary, where $\omega$ is a Dini-smooth modulus of continuity.

Strong Internal Electric Field‐Driven S‐scheme CoAl‐LDH/ZrO2 Heterojunction for Enhanced Photocatalytic CO2 Reduction: Configuration, Performance, and Mechanism

open access: yesAdvanced Science, Volume 12, Issue 45, December 4, 2025.
This study constructed an S‐scheme heterojunction catalyst CoAl‐LDH/ZrO2 driven by an internal electric field. The S‐scheme heterojunction accelerated charge separation and strengthened redox capability synergistically contribute to the superior CO2 reduction performance.Under simulated solar irradiation, optimal catalyst exhibited a CO production rate

Lectures on Nehari's Theorem on the Polydisk [PDF]

open access: yes, 2006
We give a leisurely proof of a result of Ferguson--Lacey (math.CA/0104144) and Lacey--Terwelleger (math.CA/0601192) on a Nehari theorem for "little" Hankel operators on a polydisk.

Redox Cycling and Restructuring of Silica‐Supported Bismuth Molybdate Catalysts

open access: yesChemCatChem, Volume 17, Issue 23, December 8, 2025.
Redox‐induced surface and bulk restructuring of unsupported and silica‐supported α‐bismuth molybdate (Bi2Mo3O12) were analyzed using ex‐situ and in‐situ techniques such as XPS and XAS and supported by DFT calculations. Redox cycling of Bi2Mo3O12 reveals reversible bulk and surface transformations that progressively become irreversible with cycling ...
