Micro‐Transfer Printed Continuous‐Wave and Mode‐Locked Laser Integration at 800 nm on a Silicon Nitride Platform

open access: yesLaser &Photonics Reviews, EarlyView.
A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

General‐Purpose Hexagonal Programmable Photonic Integrated Circuit with a >30 GHz Free Spectral Range

open access: yesLaser &Photonics Reviews, EarlyView.
A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Capacity building needed to reap the benefits of access to biodiversity collections

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Global conservation efforts increasingly depend on digitised natural history collections, yet the benefits of this digital data are not equally shared. We analysed biodiversity specimens and citation data from Montserrat and the Cayman Islands to assess who collected these specimens, how they are used, and by whom.

Comparison of culture media supplements identifies serum components in self-reported serum-free preparations

open access: yesStem Cell Research & Therapy
Background Cell culture media are essential for cell expansion and many cells still depend on blood-derived supplements for optimal growth. From a regulatory perspective, these materials are ideally xeno-free, serum-free or even chemically defined ...

Status and future of seed conservation of threatened plants in the post‐2020 era

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Ambitious targets have been set to backup seeds of threatened plants by the global strategy for plant conservation (GSPC), but it is unclear in how far these targets have been met and how seed collection should be organized to meet future challenges. Here, we provide an overview of the status of 44 countries in achieving seed conservation targets.

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

open access: yesPest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Three-dimensional glenohumeral relationship in cuff tear arthropathy and its correlation with the type of cuff tear

open access: yesJSES International
Objective: The main purpose of this study is to evaluate 1) the three-dimensional (3D) glenohumeral relationship in cuff tear arthropathy (CTA) and 2) the correlation between different types of rotator cuff tears (RCTs) and the 3D glenohumeral ...

OSA Endotyping as Targets for Treatment. How Far Have We Come?

open access: yesRespirology, EarlyView.
ABSTRACT Obstructive sleep apnoea (OSA) is highly prevalent and is associated with significant impairments in quality of life and comorbidity. The most common treatment employed is continuous positive airway pressure (CPAP), especially in moderate and severe cases.
