Matchings of quadratic size extend to long cycles in hypercubes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2016 Ruskey and Savage in 1993 asked whether every matching in a hypercube can be extended to a Hamiltonian cycle. A positive answer is known for perfect matchings, but the general case has been resolved only for matchings of linear size.

Pomological and technological characteristics of collected selections of cherry plum Prunus cerasifera Erhr. [PDF]
, 2005 A plantation collection containing 32 genotypes selected from spontaneous populations of cherry plum Prunus cerasifera Erhr. was set up in the region of the Eastern Serbian town of Svrljig. The fruit trees budded from Prunus cerasifera seedlings and were

The Mass Mixing Length in Convective Stellar Envelopes
, 2011 The scale length over which convection mixes mass in a star can be calculated as the inverse of the vertical derivative of the unidirectional (up or down) mass flux.

Probing gravitational non-minimal coupling with dark energy surveys
, 2017 We investigate observational constraints on a specific one-parameter extension to the minimal quintessence model, where the quintessence field acquires a quadratic coupling to the scalar curvature through a coupling constant $\xi$.

Vector boson tagged jets and jet substructure [PDF]
, 2017 In these proceedings, we report on recent results related to vector boson-tagged jet production in heavy ion collisions and the related modification of jet substructure, such as jet shapes and jet momentum sharing distributions. $Z^0$-tagging and $\gamma$

Guarded Second-Order Logic, Spanning Trees, and Network Flows [PDF]
Logical Methods in Computer Science, 2010 According to a theorem of Courcelle monadic second-order logic and guarded second-order logic (where one can also quantify over sets of edges) have the same expressive power over the class of all countable $k$-sparse hypergraphs. In the first part of the

Zero-sum partitions of Abelian groups and their applications to magic- and antimagic-type labelings [PDF]
Discrete Mathematics & Theoretical Computer ScienceThe following problem has been known since the 80s. Let $\Gamma$ be an Abelian group of order $m$ (denoted $|\Gamma|=m$), and let $t$ and $\{m_i\}_{i=1}^{t}$, be positive integers such that $\sum_{i=1}^t m_i=m-1$. Determine when $\Gamma^*=\Gamma\setminus\

Exact values for three domination-like problems in circular and infinite grid graphs of small height [PDF]
Discrete Mathematics & Theoretical Computer Science, 2019 In this paper we study three domination-like problems, namely identifying codes, locating-dominating codes, and locating-total-dominating codes. We are interested in finding the minimum cardinality of such codes in circular and infinite grid graphs of ...
