Band gap engineering in simultaneous phononic and photonic crystal slabs [PDF]

open access: yes, 2010
We discuss the simultaneous existence of phononic and photonic band gaps in two types of phononic crystals slabs, namely periodic arrays of nanoholes in a Si membrane and of Si nanodots on a SiO2 membrane. In the former geometry, we investigate in detail

Therapeutic safety and efficacy of triple-immunosuppressants versus dual-immunosuppressants in severe-to-critical COVID-19: a prospective cohort study in Bangladesh

open access: yesAnnals of Medicine, 2022
Background Hyperinflammation-induced respiratory failure is a leading cause of mortality in COVID-19 infection. Immunosuppressants such as, Baricitinib and interleukin inhibitors are the drug-of-choice to suppress cytokine storm in COVID-19.

Improved Packings of $n(n − 1)$ Unit Squares in a Square [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2021
Let $s(n)$ be the side of the smallest square into which we can pack $n$ unit squares. The purpose of this paper is to prove that $s(n^2-n)<n$ for all $n\geq 12$. Besides, we show that $s(18^2-17) < 18, s(17^2-16) < 17,$ and $s(16^2-15) < 16.$

On the symmetric square. Unit elements [PDF]

open access: yesPacific Journal of Mathematics, 1996
\textit{J.-L. Waldspurger}'s recent coherence result [Publ. Math., Inst. Hautes Etud. Sci. 81, 25-72 (1995; Zbl 0841.22009)] for the germ expansion of the orbital integral of the unit element in the Hecke algebra on the topologically unipotent set, and Kazhdan's decomposition of compact elements into topologically unipotent and absolutely semi-simple ...

Assessing Lumbar Plexus and Sciatic Nerve Damage in Relapsing-Remitting Multiple Sclerosis Using Magnetisation Transfer Ratio

open access: yesFrontiers in Neurology, 2021
Background: Multiple sclerosis (MS) has traditionally been regarded as a disease confined to the central nervous system (CNS). However, neuropathological, electrophysiological, and imaging studies have demonstrated that the peripheral nervous system (PNS)

Inefficiency in packing squares with unit squares

open access: yesJournal of Combinatorial Theory, Series A, 1978
AbstractIt is shown that, in packing a square of side n + 12 with unit squares, the wasted space always has area ⪢ n12. This answers a question of Erdös and Graham.

trans-Bis(tert-butylamine)dichloropalladium(II) [PDF]

open access: yes, 2005
The asymmetric unit of the title complex, trans-[PdCl2(NH2tBu)2], consists of two independent square-planar molecules, linked together in a hydrogen-bonding network, with the resultant alignment of the tert-butyl groups defining a two-dimensional layered

Predicting outcome in clinically isolated syndrome using machine learning

open access: yesNeuroImage: Clinical, 2015
We aim to determine if machine learning techniques, such as support vector machines (SVMs), can predict the occurrence of a second clinical attack, which leads to the diagnosis of clinically-definite Multiple Sclerosis (CDMS) in patients with a ...
