A large-mode-area all-solid photonic bandgap fiber with a seven-cell core and five high-index rod rings is investigated. Numerical simulations show that an effective area of more than 500 μm(2), a bending loss of less than 0.1 dB/m at a bending radius of 10 cm and effectively single-mode operation can be achieved simultaneously. A core diameter of 44.8 μm and an effective area of 650 μm(2) at 1064 nm are achieved in a fabricated fiber. Bending loss at 1064 nm is 0.09 dB/m at a bending radius of 7 cm. Effectively single-mode operation is also realized at a bending radius of 10 cm.

EARLY SURGERY IN RARE KNEE HETEROTOPIC OSSIFICATION LEADS TO SUCCESSFUL FUNCTIONAL OUTCOME: A CASE REPORT.

Background: Heterotopic ossification is a common complication after joint replacement surgery, such as hip or knee arthroplasty. In the intensive care unit, it is most commonly associated with traumatic brain injury or spinal cord injury. To prevent recurrence, surgical resection of heterotopic ossification is recommended once the ectopic bone has fully matured, which is estimated to occur after at least 12 months.

Complex internal stresses that appear in flexible thin-film electronic devices under long-term deformation operation are associated with incompatible mechanical properties of the multiple layers, which potentially cause intralayer fracture and separation. These defects may result in device instability, performance loss, and failure. Herein, a thermoplastic functional strategy is proposed for manufacturing high-performance stretchable semiconducting polymers with excellent strain-tolerance capacities for flexible electronic devices.

Article Synopsis
- Transition metal oxides, like MnO, show great promise as anodes for flexible electrodes but face challenges such as low conductivity and poor cycling performance.
- A new method called "spontaneous complexation and exfoliation" creates flexible thin-film electrodes using MnO nanocrystals and reduced graphene oxide (rGO), improving their mechanical flexibility and lithium-ion storage capacity.
- The resulting flexible anodes deliver around 1220 mAh/g over 1000 cycles with high-rate capacity, while maintaining performance even under bending, highlighting their potential for advanced energy storage solutions.

Current rates of habitat and biodiversity loss, and the threat they pose to ecological and economic productivity, would be considered a global emergency even if they were not occurring during a period of rapid anthropogenic climate change. Diversity at all levels of biological organization, both within and among species, and across genomes and communities, is critical for the resilience of the world's ecosystems in the face of such change. However, it remains an urgent scientific challenge to understand how biodiversity underpins these ecological outputs, how patterns of biodiversity are being affected by current threats, and how and where such biodiversity contributes most directly to human economies, well-being and social justice.

Food production does more damage to wild species than any other sector of human activity, yet how best to limit its growing impact is greatly contested. Reviewing progress to date in interventions that encourage less damaging diets or cut food loss and waste, we conclude that both are essential but far from sufficient. In terms of production, field studies from five continents quantifying the population-level impacts of land sharing, land sparing, intermediate and mixed approaches for almost 2000 individually assessed species show that implementing high-yield farming to spare natural habitats consistently outperforms land sharing, particularly for species of highest conservation concern.
