Strain‐Tunable Photoluminescence From Ge Quantum Dots on Si Nanotips for CMOS‐Compatible Photonics

open access: yesAdvanced Physics Research, EarlyView.
This work studies strain in Ge quantum dots grown on Si nanotips using photoluminescence, X‐ray diffraction, and band structure calculations. It shows how emission changes with dot size, evaluates strain in the dot and substrate, and explains the role of direct and indirect transitions in the optical behavior.

Morphometric analysis of postnatal lung development in the gray short‐tailed opossum (Monodelphis domestica): An ultrastructural study

open access: yesThe Anatomical Record, EarlyView.
Abstract An ultrastructural morphometric analysis of the postnatal development of the lung in the gray short‐tailed opossum (Monodelphis domestica) has been conducted to evaluate the morphofunctional status of this poorly developed marsupial lung immediately following parturition.

Twin pregnancies and the limits of the energetics of gestation and growth hypothesis

open access: yesThe Anatomical Record, EarlyView.
Abstract The “Energetics of Gestation and Growth” (EGG) hypothesis proposes that human birth timing and the associated secondary altriciality of human newborns is determined by limits in maternal metabolic capacity. According to this model, labor is triggered when the increasing fetal energy requirements exceed the expectant mother's maximum sustained ...

Historical birth records from 1896 to 1944 from the Basel maternity hospital, Switzerland, reveal significant obstetric selection pressures

open access: yesThe Anatomical Record, EarlyView.
Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

The synergistic impact of granulocytic myeloid‐derived suppressor cells and innate lymphoid cells in systemic sclerosis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Systemic sclerosis (SSc) is a chronic autoimmune disorder characterized by immune dysregulation and fibrosis, with myeloid‐derived suppressor cells (MDSCs) emerging as important regulators of immune responses. However, the role of MDSCs in SSc‐associated fibrosis and their interactions with other immune cell populations remain poorly ...

Dynamics of biotic resistance to plant invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...
