Semi‐supervised classification of fundus images combined with CNN and GCN

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose Diabetic retinopathy (DR) is one of the most serious complications of diabetes, which is a kind of fundus lesion with specific changes. Early diagnosis of DR can effectively reduce the visual damage caused by DR. Due to the variety and different morphology of DR lesions, automatic classification of fundus images in mass screening can ...

Muscadine (Vitis rotundifolia Michx., syn. Muscandinia rotundifolia (Michx.) Small): The Resilient, Native Grape of the Southeastern U.S

Agriculture, 2019
Angiosperms are well adapted to tolerate biotic and abiotic stresses in their native environment. However, the growth habit of native plants may not be suited for cultivation and their fruits may not be desirable for consumption.

AAPM Task Group 298: Recommendations on certificate program/alternative pathway candidate education and training

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Entry into the field of clinical medical physics is most commonly accomplished through the completion of a Commission on Accreditation of Medical Physics Educational Programs (CAMPEP)‐accredited graduate and residency program. To allow a mechanism to bring valuable expertise from other disciplines into clinical practice in medical physics, an “

Breeding and exploitation of prolific breeds in Czechoslovakia

Agricultural and Food Science, 1988
In the years 1971—1979 many experiments were conducted in order to elucidate problems of meat production increase in sheep. Ewes of native breeds (Mutton Merino = M, Improved Wallachian = I) were mated to rams of prolific breeds (Finnsheep = F, Romanov = R), producing F1 crossbred females.

Fusion breeding and pure fusion development perceptions and misperceptions [PDF]

arXiv, 2022
This paper examines fusion breeding, namely the use of 14 MeV fusion neutrons to breed $^{233}$U fuel for thermal nuclear reactors. This can be accomplished much more quickly than pure fusion. It can become main component of a power architecture that is economical, enviromentally sound and has little if any proliferation risk.

COMP Report: CPQR technical quality control guidelines for use of positron emission tomography/computed tomography in radiation treatment planning

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Positron emission tomography with x‐ray computed tomography (PET/CT) is increasingly being utilized for radiation treatment planning (RTP). Accurate delivery of RT therefore depends on quality PET/CT data. This study covers quality control (QC) procedures required for PET/CT for diagnostic imaging and incremental QC required for RTP.

Detection of selective sweeps in cattle using genome-wide SNP data [PDF]

BMC Genomics 2013, 14:382, 2012
The domestication and subsequent selection by humans to create breeds of cattle undoubtedly altered the patterning of variation within their genomes. Strong selection to fix advantageous large-effect mutations underlying domesticability, breed characteristics or productivity created selective sweeps in which variation was lost in the chromosomal region
