Variation in responses to temperature in admixed Populus genotypes predicts geographic shifts in regions where hybrids are favored

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1509-1526, February 2026.
Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North

Exiguobacterium acetylicum Strain SI17: A Potential Biocontrol Agent against Peronophythora litchii Causing Post-Harvest Litchi Downy Blight

open access: yesHorticulturae
Litchi downy blight (LDB) caused by Peronophythora litchii destroys 20–30% of litchi fruit every year and causes significant economic losses. Some Exiguobacterium strains exhibit considerable promise in both agricultural and industrial sectors.

Ages, Distances, and the Initial Mass Functions of Stellar Clusters [PDF]

open access: yes, 2000
We provide a review of the current status of several topics on the ages, distances, and mass functions of open clusters, with a particular emphasis on illuminating the areas of uncertainty.

Using rotation, magnetic activity and lithium to estimate the ages of low mass stars

open access: yes, 2014
The rotation rate, level of magnetic activity and surface lithium abundance are age-dependent quantities in stars of about a solar mass and below. The physical reasons for the evolution of these phenomena are qualitatively understood, but accurate ...

Unsymmetrical β‐Fused Blatter Radical Zinc Phthalocyanines

open access: yesChemistry – A European Journal, Volume 32, Issue 4, 23 January 2026.
Herein, we report the first synthesis of a new class of β‐fused Blatter–Zn phthalocyanines featuring a persistent radical π‐system, π–π‐driven crystal packing, and SOMO‐centered redox behavior. Single‐crystal X‐ray diffraction shows packing motifs dominated by centrosymmetric π‐π dimers.

Lateral distortional buckling of cellular composite-beams

open access: yesRevista IBRACON de Estruturas e Materiais, 2018
In the region of negative bending moments of continuous and semi-continuous steel and concrete composite beams, the inferior portion of the steel section is subjected to compression while the top flange is restricted by the slab, which may cause a global

A lithium depletion boundary age of 21 Myr for the Beta Pictoris moving group

open access: yes, 2013
Optical spectroscopy is used to confirm membership for 8 low-mass candidates in the young Beta Pic moving group (BPMG) via their radial velocities, chromospheric activity and kinematic parallaxes.

A gestão educacional e a qualidade educacional na LDB: medidas e padrões (nem sempre) congruentes

open access: yes, 2018
The present work aims at discussing how the notion of Quality (especially in what refers to Educational Quality) is presented in the Federal Constitution and LDB.

Computational Characterization of the Energetics, Structure, and Spectroscopy of Biofuel Precursors: The Case of Furfural‐Acetone‐Furfural

open access: yesJournal of Computational Chemistry, Volume 47, Issue 1, 05 January 2026.
First‐principles computational characterization of the furfural‐acetone‐furfural adduct from structural motif and conformers to vibrational and electronic spectra. ABSTRACT Using density functional theory, we identify the 30 low‐lying structures of the furfural‐acetone‐furfural adduct, a valuable biofuel precursor.

Black branes on the linear dilaton background

open access: yes, 2005
We show that the complete static black p-brane supergravity solution with a single charge contains two and only two branches with respect to behavior at infinity in the transverse space.
