Alternative designs of a superconducting synchronous generator: the Southampton approach [PDF]

open access: yes, 2008
The paper describes various designs undertaken at the University of Southampton for building both cored and coreless superconducting synchronous generators using high temperature superconducting (HTS) tapes.

Synchronous dual malignancies: Carcinoma larynx and hepatocellular carcinoma

open access: yesJournal of Radiation and Cancer Research, 2021
Synchronous cancers are defined as two or more primary cancers diagnosed in the same patient at the same time or within 6 months of diagnosis of each other. The diagnosis of multiple primary malignancies is not uncommon.

Synchronous and Asynchronous Sequential Symbol Synchronizers [PDF]

open access: yes2008 Fourth Advanced International Conference on Telecommunications, 2008
In this work, we present two synchronizer groups: the synchronous and the asynchronous. The synchronous group is based in forward logic with flip flops and the asynchronous group is based in forward logic with delay line feedback. In each group we consider two versions: the manual and the automatic.

The prognostic comparison among unilateral, bilateral, synchronous bilateral, and metachronous bilateral breast cancer: A meta‐analysis of studies from recent decade (2008‐2018)

open access: yesCancer Medicine, 2019
Background The incidence of bilateral breast cancer (BBC) is increasing nowadays comprising 2%‐11% of all breast cancer (BC). According to the interval time between the first and second cancer, BBC could be divided into synchronous (SBBC) and ...

Synchronization of Grammars [PDF]

open access: yes, 2008
Deterministic graph grammars are finite devices which generate the transition graphs of pushdown automata. We define the notion of synchronization by grammars, generalizing previous sub-classes such as visibly and height-deterministic pushdown automata.

Linking the choice of the class format and preclass learning experiences sheds light on a step further in blended medical education

open access: yesMedical Education Online, 2023
Background The core principle of HyFlex (‘hybrid’ and ‘flexible’) learning is to maintain learning equity under most circumstances. Within a blended framework in precision medical education, how different preferences of synchronous learning environment ...

Synchronization and simplification

open access: yesDiscrete Mathematics, 1979
AbstractWe describe the notions of synchronization and simplification with respect to a given subsemigroup P of a semigroup S in terms of the syntactic semigroup of P. These notions derive from coding theory, which corresponds to the case where P is a free subsemigroup of a free semigroup; we apply the results to give a unified account of several ...
