A Novel Phase‐Shifted Modulation for Balancing Current Stress During Startup of High‐Power Full‐Bridge DC/DC Converters

open access: yesThe Journal of Engineering
Traditional duty‐cycle or phase‐shift modulation is inadequate for achieving a balanced current‐stress distribution during the startup of full‐bridge DC/DC converters. As converter power capacity increases, these limitations not only restrict the startup

Leveraging genome-wide association studies to better understand the etiology of cancers. [PDF]

open access: yesCancer Sci
Recent advancements in large‐scale germline genetic analyses, represented by genome‐wide association studies (GWAS), are making it possible to elucidate the whole picture of heritable cancer risk. By applying effective statistical genetic methodologies, we can further derive biological insights beyond individual cancer‐susceptibility loci.

Nasal immature teratoma in an elderly patient: Clinicopathological and epigenetic analogies with central nervous system counterparts, alongside genomic divergences. [PDF]

open access: yesNeuropathology
Germ cell tumors (GCTs) are categorized as gonadal or extra‐gonadal, based on the origin. Extra‐gonadal GCTs predominantly manifest within the central nervous system (CNS), mediastinum, retroperitoneum, and sacrococcygeal region. These malignancies are most frequently diagnosed in the pediatric, adolescent, and young adult demographics.
