Morphological and genetic diversity of Tetragonisca angustula (Hymenoptera: Apidae) in Cundinamarca, Colombia

open access: yes, 2022
IlustracionesTetragonisca angustula es una especie del Neotrópico, conocida como abeja angelita, que se ha adaptado a ambientes con alta presión antrópica por lo que es la especie más ampliamente utilizada para cría artificial.

Repelled Point Processes With Application to Numerical Integration

open access: yesScandinavian Journal of Statistics, EarlyView.
ABSTRACT We look at Monte Carlo numerical integration from a stochastic geometry point of view. While crude Monte Carlo estimators relate to linear statistics of a homogeneous Poisson point process (PPP), linear statistics of more regularly spread point processes can yield unbiased estimators with faster‐decaying variance, and thus lower integration ...

Codes and Pseudo-Geometric Designs from the Ternary $m$-Sequences with Welch-type decimation $d=2\cdot 3^{(n-1)/2}+1$

open access: yes, 2023
Pseudo-geometric designs are combinatorial designs which share the same parameters as a finite geometry design, but which are not isomorphic to that design.

Role of Volcano‐Tectonic Interactions During Early‐Phase Magma‐Assisted Continental Rifting

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract We study volcanic‐tectonic interactions during the early phase of rifting in the Natron Rift, a magmatic segment of the East African Rift System. We use the open‐source crustal deformation modeling code, PyLith, to model deflation during the 2007–2008 explosive eruptions and inflation during 2016–2023.

Complex Shallow Unilateral Rupture of the 2025 Mw 7.0 Hubbard Glacier Earthquake Terminated by a Restraining Bend on the Connector Fault

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Despite decades of study, the detailed geometry of the Connector fault at the Alaska–Canada border remains poorly constrained. We investigate the rupture complexity and directivity of the 6 December 2025, Mw 7.0 Hubbard Glacier earthquake using hypocenter relocations, moment tensor inversions of the mainshock and aftershocks, and finite‐fault ...

Medial quasigroups of type $(n,k)$ [PDF]

open access: yes, 2010
summary:Our aim is to demonstrate how the apparatus of groupoid terms (on two variables) might be employed for studying properties of parallelism in the so called $(n,k)$-quasigroups.

Influence of boundary layer transition on the trajectory optimisation of a reusable launch vehicle

open access: yes, 2014
Based on flight experience from the Space Shuttle programme, it is well known that mis-prediction of the effects of boundary layer transition represents one of the highest technical risks when designing a Reusable Launch Vehicle.

Multidimensional Distributional Neural Network Output Demonstrated in Super‐Resolution of Surface Wind Speed

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Accurate quantification of uncertainty in neural network predictions remains a central challenge for scientific applications involving high‐dimensional, correlated data. While existing methods capture either aleatoric or epistemic uncertainty, few offer closed‐form, multidimensional distributions that preserve spatial correlation while ...

Frequency Standard Contributions to Limitations on the Signal‐to‐Noise Ratio in Very Long Baseline Interferometric Observations

open access: yesRadio Science, Volume 61, Issue 6, June 2026.
Abstract Since its observation in 2019, the first image of a super‐massive black hole using Very Long Baseline Interferometry (VLBI) with an Earth‐scale baseline has generated much scientific and public interest. Work is now underway to extend the baseline into space to obtain higher image resolution.

Size, Returns, and Value: Do Private Equity Firms Allocate Capital According to Manager Skill?

open access: yesThe Journal of Finance, Volume 81, Issue 3, Page 1661-1700, June 2026.
ABSTRACT Using a novel data set linking private equity (PE) deals to individual managers, we document evidence of manager skill in terms of generating net present value (NPV), a performance measure that captures both scale and returns. PE firms have strong economic incentives to raise larger funds and execute larger deals.
