Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

open access: yesThe Economic Journal, EarlyView., 2018
The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Fragments of Frege's Grundgesetze and G\"odel's Constructible Universe [PDF]

open access: yes, 2015
Frege's Grundgesetze was one of the 19th century forerunners to contemporary set theory which was plagued by the Russell paradox. In recent years, it has been shown that subsystems of the Grundgesetze formed by restricting the comprehension schema are ...

Internal Pattern Matching Queries in a Text and Applications

open access: yes, 2014
We consider several types of internal queries: questions about subwords of a text. As the main tool we develop an optimal data structure for the problem called here internal pattern matching.

Canola Fiber as Reinforcement for Composites: Effect of Fiber Extraction and Processing Method on Fiber Properties, Nonwoven Manufacturing, and Composite Properties

open access: yesPolymer Composites, EarlyView.
Comparison of canola fiber reinforced composites manufactured using water‐retted, field‐retted, and enzyme‐treated fibers. ABSTRACT Canola fibers obtained from discarded stalks through various processing methods, including water‐retting and field‐retting followed by mechanical decortication and enzymatic degradation, were utilized as discontinuous ...

How unprovable is Rabin's decidability theorem?

open access: yes, 2015
We study the strength of set-theoretic axioms needed to prove Rabin's theorem on the decidability of the MSO theory of the infinite binary tree. We first show that the complementation theorem for tree automata, which forms the technical core of typical ...

Cationic‐Hydrophilic Di‐Block Copolymers: Surface‐Shielded Vectors for Gene Delivery

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1419-1432, 15 March 2025.
This study develops synthetic polycationic di‐block carriers for nucleic acid (NA) delivery in gene therapy. Consisting of a cationic block and a hydrophilic block, these carriers efficiently form complexes with NAs and shield them with a protective bioinert layer, enhancing stability during circulation in the bloodstream while reducing undesirable ...

Sustainable Development Goals (SDGs) in European Countries: An Analytical and Econometric Approach

open access: yesSustainable Development, EarlyView.
ABSTRACT Despite the growing policy relevance of the Sustainable Development Goals (SDGs) within the European Union, significant uncertainties remain regarding the extent to which European countries perform unevenly across different dimensions of sustainable development and whether higher levels of economic development necessarily translate into better

Beyond Efficiency: Sufficiency Strategies for Sustainable Development in the Housing and Building Sectors

open access: yesSustainable Development, EarlyView.
ABSTRACT As the housing and building sectors face the urgent challenge of decarbonization, attention is increasingly shifting beyond conventional efficiency strategies toward the principle of sufficiency. This study explores how sufficiency can reshape the housing landscape, although there is no standardized understanding of sufficiency in these ...

The Julius Caesar objection [PDF]

open access: yes, 1997
This paper argues that that Caesar problem had a technical aspect, namely, that it threatened to make it impossible to prove, in the way Frege wanted, that there are infinitely many numbers.
