This paper investigates the construction of confidence intervals for multiple change points in linear regression models. First, we detect multiple change points by performing variable selection on blocks of the input sequence; second, we re-estimate...

Young women with endometrial cancer (EC) can choose fertility-sparing treatment for stage 1A disease without myometrial invasion (MI). The surgical diagnostic procedure (SDP) may affect the accuracy of magnetic resonance imaging (MRI) to assess MI. H...

Background: The coexistence of extracranial arterial stenoses and intracranial aneurysms presents a unique clinical dilemma. While staged interventions are traditionally preferred to reduce procedural risks, recent advances have enabled single-stage...

(1) Background: A pseudotumor of the hip is a sterile, non-neoplastic soft tissue mass associated with total hip arthroplasties. Pseudotumors may mimic soft tissue tumors or infections, and thus a differential diagnosis is crucial, and biopsy is reco...

Sheltered workshops (SW), as social enterprises, need to be efficient and maintain a balance between social aspects and economic prosperity. An important part of research on the subject has been focused on measuring the economic value created by thes...

In this work, a bivariate extension of the univariate exponentiated sinh-normal distribution is proposed. The properties of the new distribution, which is called the bivariate exponentiated sinh-normal distribution, are studied in detail, and the max...

Background/Objectives: Cryoablation is a minimally invasive treatment option for patients with a small renal mass (SRM). We aimed to present the long-term functional and oncologic outcomes of cryoablation for SRMs. Methods: We retrospectively reviewe...
