Universal Correction of Density Functional Theory to Include London Dispersion (up to Lr, Element 103) [PDF]

open access: yes, 2012
Conventional density functional theory (DFT) fails to describe accurately the London dispersion essential for describing molecular interactions in soft matter (biological systems, polymers, nucleic acids) and molecular crystals.

From Glyph to Element Symbol – A Story of Names

open access: yesCHIMIA, 2019
When I write the symbol Fe, all scientists know that I am talking about iron. Today's chemists use element symbols in formulae without thinking where they came from. This article looks at the history of element symbols and why we use the ones we

The Genetic Code as a Periodic Table: Algebraic Aspects [PDF]

open access: yes, 2000
The systematics of indices of physico-chemical properties of codons and amino acids across the genetic code are examined. Using a simple numerical labelling scheme for nucleic acid bases, data can be fitted as low-order polynomials of the 6 coordinates ...

Application of a periodic table for the genetic code to influenza A/H3N2 virus [PDF]

open access: yes, 2007
If biologists can utilize a table to have access to biological phenomena in the manner analogous to the periodic table for chemical elements, they may get hold of a directing post in life science.

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about

Chaotic dynamics in a simple bouncing ball model

open access: yes, 2010
We study dynamics of a ball moving in gravitational field and colliding with a moving table. The motion of the limiter is assumed as periodic with piecewise constant velocity - it is assumed that the table moves up with a constant velocity and then moves

Exponentially small asymptotic formulas for the length spectrum in some billiard tables [PDF]

open access: yes, 2015
Let $q \ge 3$ be a period. There are at least two $(1,q)$-periodic trajectories inside any smooth strictly convex billiard table, and all of them have the same length when the table is an ellipse or a circle.

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.
