Do L3 data indicate the existence of an isotensor meson ?

open access: yes, 2005
The QCD analysis of the hard exclusive production of $\rho^+\rho^-$ and $\rho^0\rho^0$ mesons in two photon collisions shows that the recent experimental data obtained by the L3 Collaboration at LEP can be understood as a signal for the existence of an ...

Pulsed Quantum Excitation

open access: yesLaser &Photonics Reviews, EarlyView.
This manuscript demonstrates the improvements that single photon sources can gain if their source of excitation is quantum rather than classical. Illuminating a pair of identical two‐level systems, the author shows that the excitation with pulses of quantum light yields more antibunched and more indistinguishable emission than if the excitation were ...

Chaos Warsaw?

open access: yesKwartalnik Nauk o Przedsiębiorstwie, 2019
A city is a complex creation, not only urban, occupying a specific space, but above all a collection of various socio-economic relations placed in space. The influence of space with the quality of these relations (created during the transformation under the influence of the global neoliberal economy) on shaping the space is unquestionable, hence the ...

Long‐Term Follow‐Up of Patients with Mass Social Media‐Induced Illness Presenting with Functional Tic‐like Behaviors

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Only little is known about the prognosis of functional tic‐like behaviors (FTLB), especially in the subgroup of patients with mass social media‐induced illness (MSMI‐FTLB). Objectives To provide data of long‐term follow‐up (FU) of a carefully characterized group of patients with MSMI‐FTLB to identify influencing factors such as ...

Brain Imaging Changes Following Deep Brain Stimulation Patients with Parkinson's Disease: A Literature Review

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's Disease (PD) is a progressive neurodegenerative disorder primarily characterized by motor symptoms such as tremors, rigidity, and bradykinesia. Structural brain changes, including atrophy in the midbrain, basal ganglia, and cortical regions such as the frontal and temporal lobes, are observed in advanced stages.

Regulatory B cells in the central nervous system: From immune regulation to neuroprotection

open access: yesNeuroprotection, EarlyView.
Neuroinflammatory mechanisms and the therapeutic potential of regulatory B cells (Bregs). Following brain Injury (left panel) blood–brain barrier disruption facilitates the infiltration of peripheral leukocytes, including effector B cells (Beff) and effector T cells (Teff). This process triggers the activation of macrophages, astrocytes, and microglia,

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

open access: yesNordic Journal of Botany, EarlyView.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.
