Objectives: Necrotizing external otitis(NEO) is a rare infectious disease of the skull base. The purpose of this study was to determine whether clinical outcomes of NEO can be correlated to different infectious spread ***: retrospective chart review from 2010 to 2019 with NEO patients, who were divided into two cohorts: single spreading patterns(group A) or complex spreading patterns(group B) as diagnosed by *** symptoms, diagnostic and treatment delay, course of disease, complications, and duration of antibiotic exposure were retrospectively collected from patient ***: 41 NEO patients were included, of which 27 patients belonged to group A(66%). The diseaserelated mortality rate was 12.2% among the entire cohort, no differences were found between group A and B. Higher rates of ***(42.9% vs 14.8% P = 0.047) and N. IX palsies were found in group B compared to group A(28.6% vs 3.7%, P = 0.039). The median duration of antibiotic use was significantly different for a complex spreading pattern, clinical recovery and hospitalizations. Complications were associated with higher diagnostic delay and with a complex spread pattern. The median duration of follow-up was 12.0(IQr 6.0-19.5) ***: NEO is a severe disease, with significant mortality and morbidity(cranial nerve palsies). The radiological spread pattern may assist in predicting clinical outcome. Furthermore, complex spread patterns are associated with higher rates of clinical nerve palsies(N. VII and ***), complications, surgery rates and longer duration of antibiotic use. Diagnostic delay was associated with mortality, complications and facial palsies.

This essay seeks to ascertain the various meanings of the word bam po and is mainly a contribution to its lexicography.A study of several treatises in which it occurs suggests that it,and its subordinate unit the shlo ka(rit sloka),were terms that were used to designate various lengths of the textual matter of the earliest translated Buddhist *** a unit of text,a bam po can consist of a varying number of shlo kas. Curiously,both terms also occur in several writings that do not belong to this translated literature but rather to the first indigenous,Tibetan works on *** catalographic terms,bam po and shlo ka are used in the earliest catalogs of titles of translated scripture and indigenous Tibetan literary *** is some evidence that,by fixing the length of a text,they may have been used to prevent unwarranted editorial *** is also some evidence that they played a role in the economy of text *** bam po and the shlo ka were apparently used in connection with calculating the amount of payment translators and scribes should receive for their labors.

Controlling the strain in two-dimensional （2D） materials is an interesting avenue to tailor the mechanical properties of nanoelectromechanical systems. Here, we demonstrate a technique to fabricate ultrathin tantalum oxide nanomechanical resonators with large stress by the laser oxidation of nano-drumhead resonators composed of tantalum diselenide （TaSe2）, a layered 2D material belonging to the metal dichalcogenides. Before the study of their mechanical properties with a laser interferometer, we verified the oxidation and crystallinity of the freely suspended tantalum oxide using high-resolution electron microscopy. We demonstrate that the stress of tantalum oxide resonators increases by 140 MPa （with respect to pristine TaSe2 resonators）, which causes an enhancement in the quality factor （14 times larger） and resonance frequency （9 times larger） of these resonators.
