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.

Rapid Lab‐Based In Situ Monitoring of Germanium Multiple Quantum Wells Interdiffusion

open access: yesAdvanced Physics Research, EarlyView.
This study emphasizes important insights into thermally activated diffusion control in Ge/SiGe multiple quantum wells for future design of high‐performance group‐IV optoelectronic devices. A particular fast data acquisition is achieved by in situ X‐ray diffraction and the influence of interdiffusion on the optical properties is presented by ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Revisiting the Sterilizations at Ravensbrück Concentration Camp: A Victim-Based History

open access: yesEastern European Holocaust Studies
Over decades of Holocaust scholarship, a similar narrative emerges on the sterilizations at Ravensbrück concentration camp: In January 1945, Professor Carl Clauberg experimentally sterilized between 120 and 140 Sinti and Roma women and girls in rapid ...

Romani literature and its digital forms [PDF]

open access: yes, 2020
Since the late 1990s and particularly after 2000, Romani literature has been characterized in part by the influence of international and global developments within the Romani movement as well as the growth of digital technologies and the internet. Romani

Multivariate Analysis of Hematological Stress Biomarkers and Welfare Domains in Organic and Intensive Pig Farming in Italy: A Pilot Study

open access: yesAnimal Research and One Health, EarlyView.
Intensive or organic farming systems may expose pigs to management or environmental challenges. Our preliminary results concluded that organic farming might enhance adaptive immune function, showing that improvements in welfare can translate into measurable immunological benefits, based on the correlation between welfare assessment and physiological ...

Synergistic Enhancement of Antioxidant Activity in Arbutus unedo Leaf Extract by Biological Fluids: Implications for Functional and Nutraceutical Applications

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.

Migrant success in UK Education: Are there lessons for government social mobility policy?

open access: yesBritish Educational Research Journal, EarlyView.
Abstract The school achievement and career aspirations of 23 sixth form students at a multi‐cultural urban academy in the UK are explored through interviews. The sample includes 16 s‐generation migrants, 6 UK‐born students with migrant parents and 1 UK‐born student, selected to represent a cohort of over 300 post‐16 learners.
