In this work, we present a catalog of cataclysmic variables (CVs) identified from the Sixth Data Release (DR6) Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). To single out CV spectra, introduce novel machine-learning algorithm called UMAP to screen total 169,509 H$\alpha$-emission and obtain classification accuracy over 99.6$\%$ cross-validation set. We then apply template ...

Cold urticaria can be associated with blood and thyroid disorders, drugs, or infections. Celiac disease is an autoimmune enteropathy caused by permanent gluten intolerance. It is often associated with other autoimmune diseases, such as chronic idiopathic urticaria. Nevertheless, association with cold urticaria has not yet been described. A boy aged 3 years 8 months presented local urticaria-ang...

Axonal degeneration is a hallmark of many debilitating neurological disorders and is thought to be regulated by mechanisms distinct from those governing cell body death. Recently, caspase 6 activation via amyloid precursor protein (APP) cleavage and activation of DR6 was discovered to induce axon degeneration after NGF withdrawal. We tested whether this pathway is involved in axonal degeneratio...

Clusters of galaxies in most previous catalogs have redshifts z ≤ 0.3. Using the photometric redshifts of galaxies from the Sloan Digital Sky Survey Data Release 6 (SDSS DR6), we identify 39,716 clusters in the redshift range 0.05 < z < 0.6 with more than eight luminous (Mr ≤ −21) member galaxies. Cluster redshifts are estimated accurately with an uncertainty less than 0.022. The contamination ...
