Sorting orbital angular momentum of photons through a multi-ring azimuthal-quadratic phase.

Beams carrying orbital angular momentum (OAM) already play significant roles in many domains. Here we propose a practical design of an OAM beam splitter based on a single phase-only multi-ring azimuthal-quadratic diffraction optical element that can sort different OAM components into various spatial positions, and OAM state probing is also achieved. The performance is demonstrated through proof-of-principle experiments and shows favorable results.

Radiofrequency Ablation with Continued EGFR Tyrosine Kinase Inhibitor Therapy Prolongs Disease Control in EGFR-Mutant Advanced Lung Cancers with Acquired Resistance to EGFR Tyrosine Kinase Inhibitors: Two Case Reports.

Objective: Lung cancer remains the leading cause of malignant tumor-related death globally. There is mounting evidence that a large proportion of patients harboring epidermal growth factor receptor (EGFR) mutation and treated with EGFR TKI experience oligoprogressive disease. The optimal treatment strategy for these patients is undetermined.

Clinicopathological and prognostic significance of NCALD protein expression in lung adenocarcinoma.

Background: Although there are great improvements in diagnostics and treatment of non-small cell lung cancer (NSCLC), it remains the leading cause of cancer-related death globally. NSCLC can be further categorized into two common subtypes, lung squamous cell carcinoma (LUSC) and lung adenocarcinoma (LUAD). The aims of this study were to evaluate the expression of neurocalcin delta (NCALD) in LUAD patients and to evaluate the relationship between NCALD expression and clinicopathological feature as well as overall survival (OS).
