The ability of a confocal microscope to inspect for defects on EUVL mask blanks has been investigated both experimentally and theoretically. A model was developed to predict the image contrast of a confocal microscope. Measurements were made on PSL spheres and programmed multilayer defects using a Lasertec M1350 operating with 488 nm light. The images obtained of PSL spheres on both fused silic...

Resonance-enhanced multiphoton ionization coupled with time-of-flight product imaging has been used to study the O2(Σg) + O(Pj) product channel in the UV photodissociation of ozone at photolysis wavelengths of 226, 230, 240, and 266 nm. For dissociation at 226 and 230 nm the O(P2) fragment is produced with a strongly bimodal velocity distribution, in keeping with the previous findings of Miller...

We study the algebra of SU(n)-currents in the many-flavor chiral Gross-Neveu model. The general structure of the current-current OPE leading to non-local quantum conserved charges is reviewed. We calculate the OPE in the one-flavor and the many-flavor models perturbatively and use renormalization group invariance to prove that our results are not altered by higher-order corrections. We conclude...

We report on the generation of ultrafast vortex beams in the deep ultraviolet (DUV) wavelength range at 266 nm, for the first time to our knowledge. Using a Yb-fiber-based green source in combination with two spiral phase plates of orders 1 and 2, we were able to generate picosecond Laguerre-Gaussian (LG) beams at 532 nm. Subsequently, these LG beams were frequency doubled by single-pass, secon...

Lung cancer is one of the leading causes of cancer mortality worldwide and non-small cell lung cancer (NSCLC) accounts for the most part. NSCLC can be further divided into adenocarcinoma (ACA) and squamous cell carcinoma (SCC). It is of great value to distinguish these two subgroups clinically. In this study, we compared the genome-wide copy number alterations (CNAs) patterns of 208 early stage...

The frequent use of non-representative, time-consuming and low hit rate sampling methods in the study of minority cultures is of concern. Given the increasing cultural diversity of the Canadian population and the growing Chinese population, a sampling method using phonological rules to distinguish Chinese surnames from non-Chinese ones was developed. Chinese surnames, transcribed according to t...
