Possible PCF algebras

open access: yesJournal of Symbolic Logic, 1996
AbstractThere exists a familyof sets of countable ordinals such that:(1) maxBα=α,(2) ifα∈BβthenBα⊆Bβ,(3) ifλ≤αandλis a limit ordinal thenBα∩λis not in the ideal generated by theBβ,β<α, and by the bounded subsets ofλ,(4) there is a partitionofω1such that for everyαand everyn,Bα∩Anis finite.

Cut-Off Value of Voluntary Peak Cough Flow in Patients with Parkinson’s Disease and Its Association with Severe Dysphagia: A Retrospective Pilot Study

open access: yesMedicina, 2023
Background and Objectives. Swallowing and coughing reflexes are both closely associated with airway protection. Peak cough flow (PCF) is associated with dysphagia in several neurogenic diseases. In this study, we aimed to analyze the relationship between

Full Abstraction for Probabilistic PCF [PDF]

open access: yesJournal of the ACM, 2018
We present a probabilistic version of PCF, a well-known simply typed universal functional language. The type hierarchy is based on a single ground type of natural numbers. Even if the language is globally call-by-name, we allow a call-by-value evaluation for ground-type arguments to provide the language with a suitable algorithmic expressiveness.

Design and simulation of Surface Plasmon Resonance based Solid Core Photonic crystal fiber biosensor

open access: yesJournal of Kufa-Physics, 2021
The purpose of a surface plasmon resonance (SPR)-based photonic crystal fiber (PCF) biosensor is to achieve a maximal sensitivity for the detection of unknown analytes. Outside of the PCF, the chemically stable and inert plasmonic material gold (Au) was

PCF theory and the Tukey spectrum [PDF]

open access: yesFundamenta Mathematicae, 2022
In this paper, we investigate the relationship between the Tukey order and PCF theory, as applied to sets of regular cardinals. We show that it is consistent that for all sets $A$ of regular cardinals that the Tukey spectrum of $A$, denoted $\operatorname{spec}(A)$, is equal to the set of possible cofinalities of $A$, denoted $\operatorname{pcf}(A ...

Suspended Ring-Core Photonic Crystal Fiber Gas Sensor With High Sensitivity and Fast Response

open access: yesIEEE Photonics Journal, 2015
We demonstrate the design and fabrication of an in-line evanescent field gas sensor based on a novel suspended ring-core photonic crystal fiber (PCF) to further overcome limitations in sensing capability.
