The Evolution of Classical Spiro-OMeTAD: Synthesis of Arylamine Endcapped Indenone Spirofluorene

open access: yesFrontiers in Chemistry, 2022
Spiro-OMeTAD is the well-known hole transporting material (HTM) in perovskite solar cells. In this work, its derivatives, namely four D-A shaped triphenylamine or biphenylamine endcapped indenone spirofluorene (SFD-TPA, SFD-OMeTPA, SFD-TAD, and SFD ...

Giant Gamma-ray Bubbles from Fermi-LAT: AGN Activity or Bipolar Galactic Wind?

open access: yes, 2010
Data from the Fermi-LAT reveal two large gamma-ray bubbles, extending 50 degrees above and below the Galactic center, with a width of about 40 degrees in longitude. The gamma-ray emission associated with these bubbles has a significantly harder spectrum (

Priority areas for arthropod conservation in the Iberian Peninsula and Balearic Islands: Insights from a multi‐taxon distributional database

open access: yesInsect Conservation and Diversity, EarlyView.
Using over 416,000 occurrence records from 13 arthropod groups (6233 arthropod species), we mapped large‐scale richness patterns and identified biodiversity hotspots across the Iberian Peninsula and Balearic Islands. Hotspot congruence among arthropod groups was low, underscoring the importance of integrative, multi‐taxon approaches for conservation ...

Corrected SFD: A More Accurate Galactic Dust Map with Minimal Extragalactic Contamination

open access: yesThe Astrophysical Journal, 2023
The widely used Milky Way dust-reddening map, the Schlegel–Finkbeiner–Davis (SFD) map, was found to contain extragalactic large-scale structure (LSS) imprints.

Bifurcation diagrams and multiplicity for nonlocal elliptic equations modeling gravitating systems based on Fermi-Dirac statistics

open access: yes, 2014
This paper is devoted to multiplicity results of solutions to nonlocal elliptic equations modeling gravitating systems. By considering the case of Fermi-Dirac statistics as a singular perturbation of Maxwell-Boltzmann one, we are able to produce ...

AI‐assisted basal cell carcinoma diagnosis with LC‐OCT: A multicentric retrospective study

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
Real‐time AI assistance significantly improves dermatologists' performance in diagnosing basal cell carcinoma with LC‐OCT, outperforming traditional imaging methods. AI‐assisted novices reached expert‐level performance, bridging a 2‐year expertise gap, thus supporting a broader clinical adoption of non‐invasive technologies, reducing the need for ...

Observed Binary Fraction Sets Limits on the Extent of Collisional Grinding in the Kuiper Belt

open access: yes, 2011
The size distribution in the cold classical Kuiper belt can be approximated by two idealized power laws: one with steep slope for radii R>R* and one with shallow slope for ...

A novel tissue inhibitor of metalloproteinases-3 mutation reveals a common molecular phenotype in sorsby's fundus dystrophy [PDF]

open access: yes, 2000
Sorsby’s fundus dystrophy (SFD) is a dominantly inherited degenerative disease of the retina that leads to loss of vision in middle age. It has been shown to be caused by mutations in the gene for tissue inhibitor of metalloproteinases-3 (TIMP-3 ...

Hair follicle stem cell fate supports distinct clinical endotypes in hidradenitis suppurativa

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
Hair follicles (HFs) were extracted from skin biopsies. From these, original sequencing data were obtained and integrated with two independent studies to build a HF single‐cell transcriptomic atlas. It enabled delineating the fate of HF stem cells.

MSFDmap: A novel scheme to map monthly soil freeze depth in the pan-Arctic considering spatiotemporal heterogeneity in heat transfer capability

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Accurately characterizing the spatiotemporal dynamics of soil freeze depth (SFD) is critical for understanding the response of frozen soils to climate change.
