Impact of Mg Substitution on the Structure, Stability, and Properties of the NaFeF Weberite Cathode.

Of the few weberite-type Na-ion cathodes explored to date, NaFeF exhibits the best performance, with capacities up to 184 mAh/g and energy densities up to 550 Wh/kg reported for this material. However, the development of robust structure-property relationships for this material is complicated by its tendency to form as a mixture of metastable polymorphs, and transform to a lower-energy Na FeF perovskite compound during electrochemical cycling. Our first-principles-guided exploration of Fe-based weberite solid solutions with redox-inactive Mg and Al predicts an enhanced thermodynamic stability of NaMg Fe F as the Mg content is increased, and the = 0.

Oncologic outcomes for invasive squamous cell carcinoma with a clinically resolved biopsy site managed by watchful waiting: A retrospective cohort study.

Background: Treatment of cutaneous squamous cell carcinoma (cSCC) largely involves surgical excision. Few studies have examined oncologic outcomes of tumors managed by watchful waiting (WW) when the lesion appears resolved after the biopsy site has healed.

Objective: To describe oncologic outcomes for patients diagnosed with cSCC that was determined clinically resolved at follow-up and subsequently managed by WW.

REST-dependent glioma progression occurs independently of the repression of the long non-coding RNA HAR1A.

The long non-coding RNA (lncRNA), HAR1A is emerging as a putative tumour suppressor. In non-neoplastic brain cells, REST suppresses HAR1A expression. In gliomas REST acts as an oncogene and is a potential therapeutic target.

Evaluation of a Novel Mechanical Compression Device.

Background: Venous thromboembolism (VTE) is a leading preventable cause of death in hospitalized patients. Current intermittent pneumatic compression (IPC) devices used to provide external mechanical compression for VTE prevention are associated with a multitude of clinical challenges that often result in subtherapeutic use. A comparative study was conducted of the real-world clinical use of a novel mechanical compression device (MCD) and a current IPC device.

Reflection function, reflectance, and area function measurements in ears of children and adults.

The main experiment concerned time-domain measurements of the acoustical reflection function (RF) of the human ear in adults and children (aged 5 to 8 years) using a probe inserted into the ear canal. This RF was used to calculate the area function of the ear canal versus distance along its centerline. Acoustical reflectance was calculated in the frequency domain from the RF, as was the difference in sound pressure level near the tympanic membrane relative to the probe tip.
