Variable Stars in the Newly Discovered Milky Way Dwarf Spheroidal Satellite Canes Venatici I [PDF]

open access: yes, 2007
We have identified 23 RR Lyrae stars and 3 possible Anomalous Cepheids among 84 candidate variables in the recently discovered Canes Venatici I dwarf spheroidal galaxy. The mean period of 18 RRab type stars is = 0.60 +/-0.01 days. This period, and the location of these stars in the period-amplitude diagram, suggest that Canes Venatici I is likely

The Role of Artificial Intelligence in Prospective Real-Time Histological Prediction of Colorectal Lesions during Colonoscopy: A Systematic Review and Meta-Analysis

open access: yesDiagnostics, 2023
Artificial intelligence (AI) presents a novel platform for improving disease diagnosis. However, the clinical utility of AI remains limited to discovery studies, with poor translation to clinical practice. Current data suggests that 26% of diminutive pre-

A near zero velocity dispersion stellar component in the Canes Venatici dwarf spheroidal galaxy [PDF]

open access: yesMon.Not.Roy.Astron.Soc.Lett. 373 (2006) L70-L74, 2006
We present a spectroscopic survey of the newly-discovered Canes Venatici dwarf galaxy using the Keck/DEIMOS spectrograph. Two stellar populations of distinct kinematics are found to be present in this galaxy: an extended, metal-poor component, of half-light radius 7'.8(+2.4/-2.1), which has a velocity dispersion of 13.9(+3.2/-2.5) km/s, and a more ...

Evaluation of Sugarcane Cultivation in The Khuzestan Province in the Context of Virtual Water [PDF]

open access: yesمهندسی منابع آب, 2015
The introduction of the virtual water concept raised the world’s attention toward the huge virtual displacement of water which is being done in the form of international agricultural products trade. In this regard, those countries that are suffering from

The Bramson logarithmic delay in the cane toads equations [PDF]

open access: yesarXiv, 2016
We study a nonlocal reaction-diffusion-mutation equation modeling the spreading of a cane toads population structured by a phenotypical trait responsible for the spatial diffusion rate. When the trait space is bounded, the cane toads equation admits traveling wave solutions [7].

Food Contact Compatibility of Bioplastic Materials Filled With Degradable Additives for Repeated‐Use Food Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT The packaging sector is the primary contributor to plastic waste due to the prevalence of disposable packaging. Although there is extensive literature on sustainable single‐use packaging, studies on reusable biomaterials and their compliance with food contact regulations remain scarce.

Production of a Polylactic Acid‐Based, Chitosan‐ and TiO2‐Modified Biodegradable Antimicrobial Coating Material and Investigation of Its Physical Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
Biopolymer coating synthesized with PLA and TiO2 successfully shows a very good barrier property against water on paper. It is supported by SEM that the coating has a good surface appearance. ABSTRACT Polymer wastes are increasingly threatening the environment.

Zitterbewegung and a formulation for quantum mechanics [PDF]

open access: yesarXiv, 2020
In this short note, we try to show that inside a vortex like region, like a black hole one cane observe superluminosity which yields some interesting results. Also, we consider the zitterbewegung fluctuations to obtain an interpretation of quantum mechanics.

Distances to Dwarf Galaxies of the Canes Venatici I Cloud [PDF]

open access: yes, 2013
We determined the spatial structure of the scattered concentration of galaxies in the Canes Venatici constellation. We redefined the distances for 30 galaxies of this region using the deep images from the Hubble Space Telescope archive with the WFPC2 and ACS cameras.
