Aerobic exercise therapy for chronic low back pain.

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the benefits and harms of aerobic exercise on pain, function, quality of life, psychological functioning, and adverse events, compared with placebo, sham treatment, attention control, or no treatment.

Proximity ferroelectricity in wurtzite heterostructures.

Proximity ferroelectricity is an interface-associated phenomenon in electric-field-driven polarization reversal in a non-ferroelectric polar material induced by one or more adjacent ferroelectric materials. Here we report proximity ferroelectricity in wurtzite ferroelectric heterostructures. In the present case, the non-ferroelectric layers are AlN and ZnO, whereas the ferroelectric layers are AlBN, AlScN and ZnMgO.

Assessing the Impact of Vaccination Status on Meningitis Risk Post Cochlear Implantation.

Objective: To better understand the protective benefit of pneumococcal vaccines on rates of meningitis after cochlear implantation.

Study Design: Retrospective large database review.

Setting: Several studies have shown that cochlear implantation increases the incidence of bacterial meningitis, mostly due to pneumococcal meningitis.

Identification of latent classes of randomized controlled trials based on integrity and reporting characteristics.

Objectives: Reliable, well-conducted, and adequately reported research is essential for decision-making. This study uses an exploratory clustering approach to identify patterns (subgroups) of trials based on research conduct and reporting characteristics to better understand heterogeneity. Describing features of these subgroups may help elucidate mechanisms of poor planning and reporting that can be acted upon by the research community to improve the research practices.

Nanoscale Ferroelectric Programming of van der Waals Heterostructures.

We demonstrate an approach to creating nanoscale potentials in van der Waals layers integrated with a buried programmable ferroelectric layer. Using ultra-low-voltage electron beam lithography (ULV-EBL), we can program the ferroelectric polarization in AlBN (AlBN) thin films, generating structures with sizes as small as 35 nm. We demonstrate the ferroelectric field effect with a graphene/vdW stack on AlBN by creating a p-n junction.
