Starter sequences: generalizations and applications [PDF]

open access: yes, 2018
In this thesis we introduce new types of starter sequences, pseudo-starter sequences, starter-labellings, and generalized (extended) starter sequences. We apply these new sequences to graph labeling.

Decidable fragments of first-order logic and of first-order linear arithmetic with uninterpreted predicates [PDF]

open access: yes, 2019
First-order logic is one of the most prominent formalisms in computer science and mathematics. Since there is no algorithm capable of solving its satisfiability problem, first-order logic is said to be undecidable.

The geometry and arithmetic of bielliptic Picard curves

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 5, November 2025.
Abstract We study the geometry and arithmetic of the curves C:y3=x4+ax2+b$C \colon y^3 = x^4 + ax^2 + b$ and their associated Prym abelian surfaces P$P$. We prove a Torelli‐type theorem in this context and give a geometric proof of the fact that P$P$ has quaternionic multiplication by the quaternion order of discriminant 6.

Unravelling the Electro‐Photocatalytic Water Splitting Capabilities of 2D‐Bifunctional Mo2S3‐WS2 Catalyst: Implications for Renewable Energy Platforms

open access: yesSmall Methods, Volume 9, Issue 9, September 1, 2025.
Schematic representation of band alignment and scanning transmission electron microscopy (STEM) image of Mo2S3‐WS2 nanocomposites. Abstract Addressing the energy crisis and environmental pollution demands the development of efficient electro‐ and photocatalysts capable of facilitating hydrogen production via water splitting.

5-cycle systems [PDF]

open access: yes, 2014
A k-cycle system of a multigraph G is an ordered pair (V,C) where V is the vertex set of G and C is a set of k-cycles, the edges of which partition the edges of G. A k-cycle system of lambda K_v is known as a lambda-fold k-cycle system of order v.

Does Shareholder Activism Create Value? A Meta‐Analysis

open access: yesCorporate Governance: An International Review, Volume 33, Issue 5, Page 1039-1061, September 2025.
ABSTRACT Research Question/Issue This study identifies the determinants of shareholder value created by investor activism. It quantifies and corrects the pool of published empirical estimates for bias due to the selective reporting of empirical results.

Cyclic automorphic graph decompositions [PDF]

open access: yes, 2011
Chapter 1 introduces the tools and mechanics necessary for this report. Basic definitions and topics of graph theory which pertain to the report and discussion of automorphic decompositions will be covered in brief detail.

Design of Potent Mannose‐6‐Phosphate Derivatives as Ligands for CI‐M6P/IGF2R Using Fluorescence Polarization Assay

open access: yesChemistry – A European Journal, Volume 31, Issue 41, July 22, 2025.
We designed and synthesized novel mannose‐6‐phosphate (M6P) derivatives to enhance their binding affinity for the CI‐M6P/IGF2 receptor, which plays a key role in lysosomal targeting. Using a fluorescence polarization assay, we evaluated di‐, tri‐, and penta‐M6P peptides and modified M6P analogs.

Decompositions of complete graphs into cycles of arbitrary lengths [PDF]

open access: yes, 2013
We show that the complete graph on $n$ vertices can be decomposed into $t$ cycles of specified lengths $m_1,\ldots,m_t$ if and only if $n$ is odd, $3\leq m_i\leq n$ for $i=1,\ldots,t$, and $m_1+\cdots+m_t=\binom n2$.

Is Kant's critique of metaphysics obsolete?

open access: yesPhilosophy and Phenomenological Research, Volume 111, Issue 1, Page 25-53, July 2025.
Abstract I raise a problem about the possibility of metaphysics originally due to Kant: what explains the fact that the terms in our metaphysical theories (e.g., ‘property’, ‘grounding’) refer to entities and structures (e.g., properties, grounding) in the world?
