Leveraging on ENZ Metamaterials to Achieve 2D and 3D Hyper-Resolution in Two-Photon Direct Laser Writing.

Adv Mater 2021 Mar 30:e2008644. Epub 2021 Mar 30.

Institute of Nanotechnology - Nanotec, Consiglio Nazionale delle Ricerche, Ponte P. Bucci - Cubo 33C, Rende, 87036, Italy.

A novel technique is developed to improve the resolution of two-photon direct laser writing lithography. Thanks to the high collimation enabled by extraordinary ε (near-zero) metamaterial features, ultrathin dielectric hyper-resolute nanostructures are within reach. With respect to the standard direct laser writing approach, a size reduction of 89% and 50%, in height and width respectively, is achieved with the height of the structures adjustable between 5 and 50 nm.

Modeling and optimization of simultaneous degradation of rhodamine B and acid red 14 binary solution by homogeneous Fenton reaction: a chemometrics approach.

Turk J Chem 2020 18;44(4):987-1001. Epub 2020 Aug 18.

Tofigh Daru Research and Engineering Company, Tehran Iran.

This study aimed to propose a mathematical method to investigate and optimize the simultaneous elimination process of multiple organic pollutants using the Fenton process. Hence, the treatment of rhodamine B (RB) and acid red 14 (AR14) dyes in their binary solution was studied. Multivariate curve resolution alternating least square (MCR-ALS), a novel chemometric method, was applied along with correlation constraints to resolute the UV-Vis spectrophotometric data, enabling quantification of investigated dyes despite a high spectral overlapping.

On the contributions of vision and proprioception to the representation of hand-near targets.

J Neurophysiol 2015 Jan 22;113(2):409-19. Epub 2014 Oct 22.

Department of Psychology, Trent University, Peterborough, Ontario, Canada.

Performance is often improved when targets are presented in space near the hands rather than far from the hands. Performance in hand-near space may be improved because participants can use proprioception from the nearby limb and hand to provide a narrower and more resolute frame of reference. An equally compelling alternative is that targets appearing near the hand fall within the receptive fields of visual-tactile bimodal cells, recruiting them to assist in the visual representation of targets that appear near but not far from the hand.

A dialogical exploration of the grey zone of health and illness: medical science, anthropology, and Plato on alcohol consumption.

Authors:
Kieran Bonner

Theor Med Bioeth 2009 22;30(2):81-103. Epub 2009 Feb 22.

St. Jerome's University in the University of Waterloo, Waterloo, ON, N2L 3G3, Canada.

This paper takes a phenomenological hermeneutic orientation to explicate and explore the notion of the grey zone of health and illness and seeks to develop the concept through an examination of the case of alcohol consumption. The grey zone is an interpretive area referring to the irremediable zone of ambiguity that haunts even the most apparently resolute discourse. This idea points to an ontological indeterminacy, in the face of which decisions have to be made with regard to the health of a person (e. Read More

Gig Sanit 2007 Jul-Aug(4):53-9

In the children and adolescents of the Russian Federation, there is an increase in the incidence of a number of nosological entities, a significant prevalence of chronic diseases, and a reduction in health quality in children. According to the statistical data, in the past 5 years, the overall incidence has increased by 16% in children (aged 0-14 years) (171268 per 100,000 children in 2005) by 18% in adolescents. The incidence of diseases of blood and blood-forming organs, anemias, as well diseases of the respiratory, urogenital, and nervous systems, and congenital anomalies continues to increase. Read More

Authors:
D A Rubin R M Dores

Mol Phylogenet Evol 1995 Jun;4(2):129-38

Department of Biological Sciences, University of Denver, Colorado 80208, USA.

In order to obtain a more resolute phylogeny of teleosts based on growth hormone (GH) sequences, phylogenetic analyses were performed in which deletions (gaps), which appear to be order specific, were upheld to maintain GH's structural information. Sequences were analyzed at 194 amino acid positions. In addition, the two closest genealogically related groups to the teleosts, Amia calva and Acipenser guldenstadti, were used as outgroups.
