GaN-based surface-emitting lasers (SELs) using high contrast grating (HCG) with AlN/GaN distributed Bragg reflectors were reported. The laser device achieved a threshold energy density of about 0.56 mJ/cm and the lasing wavelength was at 393.6 nm with a high degree of polarization of 73% at room temperature. The resonant mode and polarization characteristics matched to the theoretical predictio...

Staphylococcal enterotoxins (SEs) are a common causative agent of food poisoning. Recently, many new SE-like (SEl) toxins have been reported, although the role of SEls in food poisoning remains unclear. In this study, the emetic potentials of SElK, SElL, SElM, SElN, SElO, SElP, and SElQ were assessed using a monkey-feeding assay. All the SEls that were tested induced emetic reactions in monkeys...

S35 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 VID-LUM-01 A case of “rolling” esophagus lumps and bumps Keat Hong Lee, How Cheng Low, Gim Hin Ho National University Hospital, Singapore Case Report: A 47-year-old gentleman was referred from GP clinic for postprandial abdominal bloating for 2 months associated with early satiety. There was no weight loss/ dysphagia/odynophagia/...

Hydroxide-exchange-membrane water electrolysis (HEMWE) is an emerging hydrogen-production pathway that combines many advantages of incumbent alkaline (AWE) and proton-exchange-membrane (PEMWE). Advancement in HEMWE has been accelerated with the development stable conductive hydroxide exchange membranes (HEMs) a more comprehensive understanding gas-evolving kinetics. However, performance durabil...

Open Access Gastrointestinal subepithelial lesions (SELs) are masses or bulges covered by normal appearing mucosa and are usually found incidentally during endoscopy. 1 There are various types of gastric SELs, ranging from benign lesions to lesions with malignant potential. Endoscopic ultrasonography (EUS) is the most reliable diagnostic modality for gastric SELs, and provides helpful informati...

Present-day operational tornado forecasting can be thought of in two parts: anticipation of tornadic potential in the storm environment, and recognition of tornadic storms once they develop. The former is a forecasting issue, while the latter is associated with warnings (or so-called nowcasting). This paper focuses on the forecasting aspect of tornadoes1, by dealing primarily with the relations...

Staphylococcus aureus produces a wide variety of toxins including staphylococcal enterotoxins (SEs; SEA to SEE, SEG to SEI, SER to SET) with demonstrated emetic activity, and staphylococcal-like (SEl) proteins, which are not emetic in a primate model (SElL and SElQ) or have yet to be tested (SElJ, SElK, SElM to SElP, SElU, SElU2 and SElV). SEs and SEls have been traditionally subdivided into cl...
