Multilocus sequence typing of the invasive pest Halyomorpha halys (Hemiptera: Pentatomidae) and associated endosymbiont reveals unexplored diversity

open access: yesInsect Science, EarlyView.
A multilocus sequence typing approach is proposed to explore Halymorpha halys genetic diversity, taking into consideration both insect nuclear markers and markers from the gut symbiont “Candidatus Pantoa carbekii.” Increased information was revealed regarding the number of distinct holobiont haplotypes in native and invasive populations of the pest ...

Long-persisting SARS-CoV-2 spike-specific CD4+ T cells associated with mild disease and increased cytotoxicity post COVID-19

open access: yesNature Communications
The recent COVID-19 pandemic left behind the lingering question as whether new variants of concern might cause further waves of infection. Thus, it is important to investigate the long-term protection gained via vaccination or exposure to the SARS-CoV-2 ...

Evolution and control of the phase competition morphology in a manganite film

open access: yes, 2015
The competition among different phases in perovskite manganites is pronounced since their energies are very close under the interplay of charge, spin, orbital and lattice degrees of freedom.

The enigmatic case of Lipoptena sp. in the Bosco della Mesola Nature Reserve (Italy)

open access: yesMedical and Veterinary Entomology, EarlyView.
This is the first report of Lipoptena andaluciensis in Italy, confirmed morphologically and genetically. The presence of L. andaluciensis in Italy dates back many years; it was found on cervids in lowland habitats. A re‐examination of the previous report of the Italian L. fortisetosa is needed.

Pilot Study Evaluating the Early Clinical Outcomes Obtained with a Novel, Customized, Multifocal Corneo-Scleral Contact Lens for Presbyopia Correction

open access: yesLife
Background: The objective was to preliminarily evaluate the short-term clinical outcomes obtained in presbyopic patients with a novel, multifocal, customized corneo-scleral contact lens (CSCL). Methods: A total of 11 presbyopic subjects (age 45–80 years,

The Many Electron Ground State of the Adiabatic Holstein Model in Two and Three Dimensions

open access: yes, 2004
We present the complete ground state phase diagram of the Holstein model in two and three dimension considering the phonon variables to be classical. We first establish the overall structure of the phase diagram by using exact diagonalisation based Monte

Molecular Phylogeny, Species Delimitation, and Biogeography of the Varunid Crab Genus Metaplax (Crustacea, Varunidae)

open access: yesZoologica Scripta, EarlyView.
ABSTRACT The Indo‐West Pacific genus Metaplax comprises 11 recognised species inhabiting intertidal mudflats, some adjacent to mangroves. To resolve long‐standing uncertainties, we analysed mitochondrial (COI, 16S) and nuclear (28S) markers. Phylogenetic analyses recovered Metaplax as monophyletic and resolved four well‐supported clades—the M ...

First Record of Triops cancriformis (Branchiopoda: Notostraca) in Qatar: Its Origin and Range Expansion Inferred From Genetics, Morphology, and Reproduction

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
First record of Triops cancriformis is reported in Qatar using genetic, morphological, and reproductive data. The closest relative of this population is found in Germany. Dispersal of propagules is believed to be via avian seasonal migration. ABSTRACT The presence of Triops cancriformis has not been broadly reported outside Europe or North Africa ...

Photoinduced charge and spin dynamics in strongly correlated electron systems

open access: yes, 2006
Motivated by photoinduced phase transition in manganese oxides, charge and spin dynamics induced by photoirradiation are examined. We calculate the transient optical absorption spectra of the extended double-exchange model by the density matrix ...

DNA barcoding reveals the coral “laboratory-rat”, Stylophora pistillata encompasses multiple identities [PDF]

open access: yes, 2013
Stylophora pistillata is a widely used coral “lab-rat” species with highly variable morphology and a broad biogeographic range (Red Sea to western central Pacific).
