Charmonium-like resonances with JPC = 0++, 2++ in coupled D D ¯ $$ \mathrm{D}\overline{\mathrm{D}} $$ , D s D ¯ s $$ {\mathrm{D}}_{\mathrm{s}}{\overline{\mathrm{D}}}_{\mathrm{s}} $$ scattering on the lattice

Journal of High Energy Physics, 2021
We present the first lattice investigation of coupled-channel D D ¯ $$ D\overline{D} $$ and D s D ¯ s $$ {D}_s{\overline{D}}_s $$ scattering in the J PC = 0++ and 2++ channels.

Network topology drives population temporal variability in experimental habitat networks

Population Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

Population Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Molecular states from $$D^{(*)}{\bar{D}}^{(*)}/B^{(*)}{\bar{B}}^{(*)}$$ D ( ∗ ) D ¯ ( ∗ ) / B ( ∗ ) B ¯ ( ∗ ) and $$D^{(*)}D^{(*)}/{\bar{B}}^{(*)}{\bar{B}}^{(*)}$$ D ( ∗ ) D ( ∗ ) / B ¯ ( ∗ ) B ¯ ( ∗ ) interactions

European Physical Journal C: Particles and Fields, 2020
In this work, we preform a systematic investigation about hidden heavy and doubly heavy molecular states from the $$D^{(*)}{\bar{D}}^{(*)}/B^{(*)}{\bar{B}}^{(*)}$$ D ( ∗ ) D ¯ ( ∗ ) / B ( ∗ ) B ¯ ( ∗ ) and $$D^{(*)}D^{(*)}/{\bar{B}}^{(*)}{\bar{B}}^{(*)}$$

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

Population Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using

Decay widths of $$^3 P_J$$ 3 P J charmonium to $$DD,DD^*,D^*D^*$$ D D , D D ∗ , D ∗ D ∗ and corresponding mass shifts of $$^3 P_J$$ 3 P J charmonium

European Physical Journal C: Particles and Fields, 2020
In this work, we calculate the amplitudes of the processes $$c{{\bar{c}}}({^3P_J}) \rightarrow DD,DD^*, D^*D^* \rightarrow c\bar{c}({^3P_J})$$ c c ¯ ( 3 P J ) → D D , D D ∗ , D ∗ D ∗ → c c ¯ ( 3 P J ) in the leading order of the nonrelativistic expansion.

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Population Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Charge asymmetry in decays B → D D ¯ K $$ D\overline{D}K $$

Journal of High Energy Physics, 2020
We discusses the charge asymmetry in B → D D ¯ K $$ D\overline{D}K $$ decays with an invariant mass of the D D ¯ $$ D\overline{D} $$ pair near the Ψ(3770) resonance.

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

Population Ecology, EarlyView.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...
