Dwork crystals I [PDF]

open access: yes, 2021
We present an elementary elaboration of Dwork's idea of explicit $p$-adic limit formulas for zeta functions of toric hypersurfaces.Comment: This version is identical with the earlier one, we only change the numeration of theorems so that it agrees with

Duality relations for hypergeometric series [PDF]

open access: yes, 2014
We explicitly give the relations between the hypergeometric solutions of the general hypergeometric equation and their duals, as well as similar relations for q-hypergeometric equations.

Prevalence and Spirometric Transitions of PRISm and Obstruction: A Population-Based Study. [PDF]

open access: yesRespirology
PRISm and obstruction exhibit distinct physiological trajectories with reductions in FVC and TLC and preserved MMEF/FVC in incident PRISm, while increased RV/TLC and reduced MMEF/FVC were observed in incident obstruction. While LLN‐based definitions aligned better with age‐related physiology, applying fixed thresholds alongside STAR‐staging revealed ...

Geodesic continued fractions and LLL [PDF]

open access: yes, 2013
We discuss a proposal for a continued fraction-like algorithm to determine simultaneous rational approximations to $d$ real numbers $\alpha_1,\ldots,\alpha_d$. It combines an algorithm of Hermite and Lagarias with ideas from LLL-reduction. We dynamically

A model study of enhanced oil recovery by flooding with aqueous surfactant solution and comparison with theory [PDF]

open access: yes, 2015
With the aim of elucidating the details of enhanced oil recovery by surfactant solution flooding, we have determined the detailed behavior of model systems consisting of a packed column of calcium carbonate particles as the porous rock, n-decane as the ...

Utilization of waste glass with natural pozzolan in the production of self-glazed glass-ceramic materials

open access: yesNanotechnology Reviews, 2023
Significant self-glazed glass-ceramic was obtained from a natural pozzolan and external glass cullet. Natural pozzolan with/without glass cullet was fused to glass melt that quenched in water to glass frits. The dried glass frits were pulverized (
