Compound Meta-Optics for Advanced Optical Engineering

open access: yesSensors
Compound meta-optics, characterized by the unprecedented complex optical architectures containing single or multiple meta-optics elements, has emerged as a powerful paradigm for overcoming the physical limitations of single-layer metasurfaces.

ON COMMON GOOD, MONEY AND CREDIT [PDF]

open access: yes, 2014
As Kosick maintained, homo oeconomicus is not only a theoretical aberration, it is an aberration of reality. The idea of human beings that Neo-classical Economics portrays is, without a doubt, a degeneration, and does little as the explicative axis of ...

Pulmonary Dysfunction Is Associated With Sleep Study Abnormalities in Children With Sickle Cell Disease: A Multicenter Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

Uniform fractional factorial designs

open access: yes, 2012
The minimum aberration criterion has been frequently used in the selection of fractional factorial designs with nominal factors. For designs with quantitative factors, however, level permutation of factors could alter their geometrical structures and ...

Financial Burden Associated With Hospitalisation Among Families of Childhood Brain Tumours in Australia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Change in choroid thickness and vascularity index associated with accommodation and aberration after small-incision lenticule extraction [PDF]

open access: yesInternational Journal of Ophthalmology
AIM: To explore choroidal thickness (CT) and choroidal vascularity index (CVI) changes around the macula and optic nerve head (ONH) using swept-source optical coherence tomography (SS-OCT) after small-incision lenticule extraction (SMILE) and evaluate ...

Axial range of conjugate adaptive optics in two-photon microscopy

open access: yes, 2015
We describe an adaptive optics technique for two-photon microscopy in which the deformable mirror used for aberration compensation is positioned in a plane conjugate to the plane of the aberration.

Aberration in qualitative multilevel designs

open access: yes, 2015
Generalized Word Length Pattern (GWLP) is an important and widely-used tool for comparing fractional factorial designs. We consider qualitative factors, and we code their levels using the roots of the unity. We write the GWLP of a fraction ${\mathcal F}$

‘They Need to Hear You Say It’: Healthcare Professionals’ Perspectives on Barriers and Enablers to End‐of‐Life Discussions With Adolescents and Young Adults With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...
