Matching $\leq$ Hybrid $\leq$ Difference in Differences
Since LaLonde's (1986) seminal paper, there has been ongoing interest in estimating treatment effects using pre- and post-intervention data. Scholars have traditionally used experimental benchmarks to evaluate the accuracy of alternative econometric methods, including Matching, Difference-in-Differences (DID), and their hybrid forms (e.g., Heckman et ...

The UK Aircraft Noise Index Study: 20 Years on. [PDF]
, 2004 In the early 1980s the UK Department of Transport (now the Department for Transport: DfT is used here to cover all its incarnations) commissioned a study to determine what index should be used to assess aircraft noise disturbance near major airports ...

Tully-Fisher Relation of Late-type Galaxies at $0.6 \leq z \leq 2.5$ [PDF]
We present a study of the stellar and baryonic Tully-Fisher relation within the redshift range of $0.6 \leq z \leq 2.5$ utilizing observations of \sfgs. This dataset, as explored in \citet{GS23}, comprises of disk-like galaxies spanning a stellar mass range of $8.89 \leq \log(M_{star} \ [\mathrm{M_\odot}]) \leq 11.5$, baryonic mass range of $9.0 \leq ...

Results in Optics, 2023 We show that with an adequate choice of geometric parameters, such as the position of the active medium in the cavity, it is possible to design a laser cavity where the lens effects due to population and saturation inhomogeneities would be simultaneously

Noise pollution in rail transport. Case study: Baghdad subway
Noise Mapping, 2022 Noise pollution is one of the environmental factors that severely threaten humans’ mental, emotional, and physical health. One of the most significant sources of this pollution is the noise generated by traffic and urban transportation, mainly the urban ...

Journal of Inequalities and Applications, 2021 Let S be a self-mapping on a normed space X ${\mathcal{X}}$ . In this paper, we introduce three new classes of mappings satisfying the following conditions: max 0 ≤ k ≤ m k even ∥ S k x − S k y ∥ = max 0 ≤ k ≤ m k odd ∥ S k x − S k y ∥ , max 0 ≤ k ≤ m ...

Об одной открытой проблеме теории модулярных подгрупп
Журнал Белорусского государственного университета: Математика, информатика, 2023 Пусть $G$ — конечная группа. Подгруппа $A$ группы $G$ называется модулярной в $G$, если (i) $\langle X, A \cap Z \rangle=\langle X, A \rangle \cap Z$ для всех $X \leq G, Z \leq G$ таких, что $X \leq Z,$ и (ii) $\langle A, Y \cap Z \rangle=\langle A, Y ...

Fraction of Clumpy Star-Forming Galaxies at $0.5\leq z\leq 3$ in UVCANDELS: Dependence on Stellar Mass and Environment [PDF]
, 2023 High-resolution imaging of galaxies in rest-frame UV has revealed the existence of giant star-forming clumps prevalent in high redshift galaxies. Studying these sub-structures provides important information about their formation and evolution and informs
