Photon recoil momentum in a Bose-Einstein condensate of a dilute gas [PDF]

, 2017
We develop a "minimal" microscopic model to describe a two-pulse-Ramsay-interferometer-based scheme of measurement of the photon recoil momentum in a Bose-Einstein condensate of a dilute gas [Campbell et al., Phys. Rev. Lett. 94, 170403 (2005)].

Synthetic Strategies to Access Fluorinated Azoles

European Journal of Organic Chemistry, Volume 28, Issue 47, December 15, 2025.
This review highlights recent synthetic strategies for introducing fluorine groups (mono‐, di‐, and trifluoromethylation) into 11 major azole classes, identifying research gaps to inform future innovations in materials science, medicinal chemistry, and biomedical research.

3-(5-Phenyl-2H-tetrazol-2-yl)pyridine

Molbank, 2023
3-(5-Phenyl-2H-tetrazol-2-yl)pyridine was synthesized by treating 5-phenyl-1H-tetrazole with pyridin-3-ylboronic acid under Chan–Evans–Lam coupling conditions. The structure and identity were confirmed by 1H, 13C-NMR spectroscopy, IR spectroscopy, UV–Vis

Decoding of Quasi-Cyclic Codes up to A New Lower Bound on the Minimum Distance

, 2014
A new lower bound on the minimum Hamming distance of linear quasi-cyclic codes over finite fields is proposed. It is based on spectral analysis and generalizes the Semenov- Trifonov bound in a similar way as the Hartmann-Tzeng bound extends the BCH ...

Host Co‐Occurrence and Population Size Explain Genetic Differentiation and Diversity in Seal Lice

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT We studied the drivers of population‐genetic structuring and genetic diversity in specialist parasites based on whole‐genome resequencing data from 82 Echinophthirius horridus seal louse individuals sampled from 12 ecologically and behaviourally different phocine seal species, subspecies and populations across the Holarctic.

Comment on "On the uncertainty relations and squeezed states for the quantum mechanics on a circle"

, 2002
It is shown by examples that the position uncertainty on a circle, proposed recently by Kowalski and Rembieli\'nski [J. Phys. A 35 (2002) 1405] is not consistent with the state localization.

Square-full polynomials in short intervals and in arithmetic progressions [PDF]

, 2016
We study the variance of sums of the indicator function of square-full polynomials in both arithmetic progressions and short intervals. Our work is in the context of the ring $F_{q}[T]$ of polynomials over a finite field $F_{q}$ of $q$ elements, in the ...

Historical Biogeography of Spiny Lobsters in the Genus Panulirus (Achelata: Palinuridae)

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim Panulirus is the spiny lobster genus with the most living species, containing 22 recognised species split into two lineages distinguished by habitat preference. Diversification has been proposed to occur due to geographic events affecting the distribution of adults and the dispersal potential of long‐lived larvae by oceanic currents ...

Plants for Wild Bees—Field Records in Bulgaria

Diversity
One of the eight shortfalls in European wild bee data is the knowledge of the flowering plants they favor. This knowledge is of particular importance for bee gardens and wildflower strips initiatives aiming to provide forage for the wild bees. The aim of

Impurity-induced modulation of terahertz waves in optically excited GaAs

AIP Advances, 2017
The effect of the photoinduced absorption of terahertz (THz) radiation in a semi-insulating GaAs crystal is studied by pulsed THz transmission spectroscopy.
