Driven predominantly by public and private innovation, rechargeable batteries have, over a few decades, graduated from powering luxury consumer electronics to becoming one of the linchpins of the energy transition. Rapid adoption trends of batteries must accelerate to meet global net-zero targets for mobility and stationary storage, and will require making sound investments in battery innovation that deliver the most value. Because battery innovation is increasingly complex, multi-disciplinary, and subject to the coordination of stakeholders across academia, industry, government, and the broader public, building common and intuitive frameworks for understanding becomes critical to making progress.

We hypothesize that military-relevant publications are underrepresented in the scientific literature and that such publications decrease significantly during peacetime.
Methods: We identified high impact journals in the fields of Medicine, Surgery and Critical Care and developed Boolean searches for military-focused topics using National Library of Medicine Subject Headings terms.
Tinnitus is the perception of a continuous sound in the absence of an external source. Although the role of the auditory system is well investigated, there is a gap in how multisensory signals are integrated to produce a single percept in tinnitus. Here, we train participants to learn a new sensory environment by associating a cue with a target signal that varies in perceptual threshold.

Objectives: Approximately 30% of patients develop chronic poststernotomy pain (CPSP) following cardiac surgery with sternal retraction. Risk factors have been described but no causal determinants identified. Investigators hypothesized that opening the sternum slowly would impart less force (and thereby less nerve/tissue damage) and translate to a reduced incidence of CPSP.

Although the radiographic results and functional scores are more or less satisfactory for open ligamentoplasty, it is often responsible for a decrease in joint amplitude postoperatively. Arthroscopic techniques are therefore of great interest, since they respect the joint capsule, but they remain technically difficult and demanding surgeries, requiring a good deal of experience in arthroscopy and using bone tunnels that are potentially a source of complications, as well as pinning to the palmar side of the wrist, which is potentially dangerous for the palmar structures of the wrist.

Data Sources: A systematic search of PubMed, Embase, and the Cochrane databases was conducted up to December 31, 2021.
Study Selection: Previously peer-reviewed observational studies that reported ICU, mechanical ventilation (MV), renal replacement therapy (RRT) or extracorporeal membrane oxygenation (ECMO)-related mortality among greater than or equal to 100 individual patients.
Background: Physicians and physicians-in-training have repeatedly demonstrated poor accuracy of global self-assessments, which are assessments removed from the context of a specific task, regardless of any intervention. Self-monitoring, an in-the-moment self-awareness of one's performance, offers a promising alternative to global self-assessment. The purpose of this scoping review is to better understand the state of self-monitoring in graduate medical education.

Objective: Our systematic review aimed to evaluate the impact of botulinum toxin injection into the masticatory muscles on mandibular bone based.
Methods: PubMed, Embase, Ovid, CINAHL and Web of Science were searched for human studies assessing mandibular bone after injection of BoNTA using computed tomography (CT) and cone beam CT (CBCT).
Background: Consensus recommendations regarding the threshold levels of cardiac troponin elevations for the definition of perioperative myocardial infarction and clinically important periprocedural myocardial injury in patients undergoing cardiac surgery range widely (from >10 times to ≥70 times the upper reference limit for the assay). Limited evidence is available to support these recommendations.
Methods: We undertook an international prospective cohort study involving patients 18 years of age or older who underwent cardiac surgery.
Importance: Given limited COVID-19 vaccine availability early in the pandemic, optimizing immunization strategies was of paramount importance. Ring vaccination has been used successfully to control transmission of other airborne respiratory viruses.
Objective: To assess the association of a ring vaccination intervention on COVID-19 spread in the initial epicenter of SARS-CoV-2 Alpha variant transmission in Montreal, Canada.
Mimicking natural parameters and complexities in zoo conservation breeding programs can facilitate natural physiological and behavioral traits, which in turn can inform more effective species reintroduction efforts. To curtail population declines of threatened narrow-headed gartersnakes (Thamnophis rufipunctatus), the Arizona Center for Nature Conservation/Phoenix Zoo partnered with a multiagency conservation working group to develop an ex situ propagation-for-release program. Initially, Zoo staff followed common snake husbandry protocols of manually inducing brumation (i.
