Congenital hairy polyps are exceedingly rare congenital anomalies. We report a case of congenital hairy polyp arising from posterior tonsillar pillar which was excised with bipolar cautry.

The aggregate morphology of a CO2-responsive pillar[5]arene was reversibly controlled between toroid-like assemblies and irregular aggregates by bubbling CO2 and N2 repeatedly.

In mining of inclined coal seams in Tangshan coal mine of Kailuan group, gateways on either end of a panel were both typically located along the floor and a gateway pillar between adjoining panels was left unmined between adjacent panels to ensure stability, thus forming a planar mining system. According to the practice, however, it turned out that this conventional mining system has long-stand...

The understanding of force interplays between an organism and its environment is imperative in biological processes. Noticeably scarce from the study of C. elegans locomotion is the measurement of the nematode locomotion forces together with other important locomotive metrics. To bridge the current gap, we present the investigation of C. elegans muscular forces and locomotion metrics (speed, am...

Introduction Gastroesophageal reflux disease (GERD) is a major public health problem. The "gold standard" in the surgical treatment of this condition is the laparoscopic technique called Nissen fundoplication. Aim This paper presents a safer alternative of the laparoscopic Nissen fundoplication, with special focus on the most difficult moment of the intervention, the creation of a retroesophage...

Non-conductive film with Zn nano-particles (Zn-NCF) is an effective solution for fine-pitch Cu-pillar/Sn– Ag bump interconnection in terms of manufacturing process and interfacial reliability. In this study, NCFs with Zn nano-particles of different acidity, viscosity, and curing speed were formulated and diffused Zn contents in the Cu pillar/Sn–Ag bumps were measured after 3D TSV chip-stack bon...

during the past decade, the world economic forum has published its annual reports in which the global competitiveness index is included. this paper aims to investigate the key factors for achieving an innovation-driven economy. in this paper, we used partial canonical correlation analysis (pcca) to examine the relationships between key pillars in “efficiency enhancers” and “business sophisticat...

A planar-chiral pillar[5]arene derivative containing one π-conjugated unit was prepared. Chiroptical changes were observed upon addition of the achiral guest 1,4-dicyanobutane.
