An all-fiber focused perfect vortex beam (PVB) generator is reported and fabricated by using 3D printing technology. The generator is constructed by integrating a designed spiral axicon zone plate (SAZP) on the fiber-end facet. The ring diameters of the generated beams are independent of the topological charges and positively correlated with the wave vectors in the transverse direction. By controlling the axicon angle, the ring diameter can be freely adjusted.

1 Introduction Breast cancer (BC) is the most prevalent malignant tumor in women globally and one of the major causes of cancer-related death in women.[1] Breast cancer is divided into four subtypes based on IHC results for estrogen receptor (ERα), progesterone receptor (PR), human epidermal growth factor receptor-2 (HER2), and the tumor cell proliferation index (Ki-67):[2] Luminal A, Luminal B, HER2 positive and basal-like breast cancer (BLBC).

AbstractCancer development is associated with adaptation to various stressful conditions, such as extracellular acidosis. The adverse tumor microenvironment also selects for increased malignancy. Mitochondria are integral in stress sensing to allow for tumor cells to adapt to stressful conditions.

AbstractA high-resolution carbon dioxide emission inventory is essential for accurate carbon emission assessment and management. This study used a top-down spatial proxy model to develop a high-resolution (1 km) carbon dioxide emission inventory for East Asia from 2012 to 2021. Combining multiple data sources with geographically weighted regressions can improve the accuracy of the spatial distribution of sectors within carbon dioxide inventories.

Direct β-C–H ketoalkylation of enaminoesters with cyclopropanols under metal-free conditions A TEMPO-mediated β-ketoalkylation of enaminoesters with cyclopropanols under metal-free conditions is herein described. This reaction provides a straightforward and highly efficient route to β-keto alkyl substituted enaminoesters for the first time, which could be rapidly and efficiently converted into synthetically useful 2-alkoxycarbonyl functionalized 1,5-diketones.
