Real Spectrum Versus ℓ-Spectrum via Brumfiel Spectrum [PDF]
Algebras and Representation Theory, 2021 It is well known that the real spectrum of any commutative unital ring, and the ${\ell}$-spectrum of any Abelian lattice-ordered group with order-unit, are all completely normal spectral spaces. We prove the following results: (1) Every real spectrum can be embedded, as a spectral subspace, into some ${\ell}$-spectrum. (2) Not every real spectrum is an

Spectrum matching in licensed spectrum sharing [PDF]
Transactions on Emerging Telecommunications Technologies, 2018 AbstractSpectrum sharing is one of the promising solutions to meet the spectrum demand in fifth‐generation networks that results from the emerging services like machine‐to‐machine and vehicle‐to‐infrastructure communication. The idea is to allow a set of entities to access the spectrum whenever and wherever it is unused by the licensed users.

Local spectrum and generalized spectrum [PDF]
Proceedings of the American Mathematical Society, 1991 This paper provides the proofs of those results announced in [ 5 , § 5 ] [5,\S 5] that deal with the connection between the regular set and the local resolvant set of closed operators on a Hilbert space. We also give some characterizations and properties of Cowen-Douglas operators.

A patient with diffuse alveolar hemorrhage: A diagnostic dilemma
Respiratory Medicine Case Reports, 2020 Diffuse alveolar hemorrhage (DAH) is a usual presentation of pulmonary vasculitis. However, several rare conditions have a similar presentation. We present a 73-year-old man with DAH whose diagnosis only became conclusive near the end of his life.

Practical Evaluation Method of Large Size IRS: Synthesis of Reflection Pattern of Sub-IRS
IEEE Access, 2023 Intelligent reflecting surfaces (IRSs) have been attracting attention as a solution to coverage hole problems in millimeter-wave communication areas and are considered one of the key technologies of next-generation mobile communication systems.

Axillary metastases after port site recurrences of gallbladder carcinoma: a case report
World Journal of Surgical Oncology, 2020 Background Incidental gallbladder carcinoma is often discovered after elective laparoscopic cholecystectomy for cholecystitis or cholecystolithiasis. Port site recurrences may occur. Patients with port site metastases of gallbladder carcinoma have a poor

The Autism Spectrum Disorder Evaluative Education Model
SAGE Open, 2014 Evaluating educational programs and interventions is generally considered a normal part of curriculum development and improvement, and published findings are readily accessible through peer-reviewed journals. Recently, however, researchers and practicing
