Subrings which are closed with respect to taking the inverse
, 2007 Let S be a subring of the ring R. We investigate the question of whether S intersected by U(R) is equal to U(S) holds for the units. In many situations our answer is positive.

Epilepsia, EarlyView.Abstract Objective Epilepsy affects ~1% of the global population and often requires lifelong antiseizure medication (ASM) therapy. Valproic acid (VPA) is a commonly prescribed first‐line ASM, yet only approximately half of patients achieve sustained seizure freedom. Treatment selection remains largely empirical.

A characterization of soluble groups in which normality is a transitive relation [PDF]
International Journal of Group Theory, 2017 A subgroup $X$ of a group $G$ is said to be an H-subgroup if NG(X) ∩ Xg ≤ X for each element $g$ belonging to $G$. In [M. Bianchi and e.a., On finite soluble groups in which normality is a transitive relation, J.

Approximation of proximities by aggregating T-indistinguishability operators [PDF]
, 2007 For a continuous Archimedean t-norm T a method to approximate a proximity relation R (i.e. a reflexive and symmetric fuzzy relation) by a T-transitive one is provided.

, 2017 We consider the two-variable fragment of first-order logic with one distinguished binary predicate constrained to be interpreted as a transitive relation.

International Journal of Cancer, EarlyView.Optimizing neoadjuvant therapy for muscle‐invasive bladder cancer patients who are eligible for cisplatin remains difficult, owing particularly to high toxicity and recurrence rates. This meta‐analysis compared dose‐dense methotrexate, vinblastine, doxorubicin, and cisplatin (ddMVAC) against durvalumab plus gemcitabine‐cisplatin (D‐GC) and GC alone ...

Transforming Solutions for the Oberwolfach Problem into Solutions for the Spouse‐Loving Variant
Journal of Combinatorial Designs, EarlyView.ABSTRACT The Oberwolfach problem OP ( F ) $\mathrm{OP}(F)$, for a 2‐factor F $F$ of K n ${K}_{n}$, asks whether there exists a 2‐factorization of K n ${K}_{n}$ (if n $n$ is odd) or K n − I ${K}_{n}-I$ (if n $n$ is even) where each 2‐factor is isomorphic to F $F$. Here, I $I$ denotes any 1‐factor of K n ${K}_{n}$. For even n $n$, the problem OP( F ) $(F)

PROPERTIES OF HYPERPRODUCTS AND THE RELATION β IN QUASIHYPERGROUPS
Ratio Mathematica, 1997 Some properties of the complete parts in hyper-groupoids are established. Applying these properties to the case of quasihypergroups H for which H/β*. is a quasigroup, a necessary and sufficient condition for the transitivity of the relation β is proved ...

Phase Transitions Related to the Pigeonhole Principle [PDF]
, 2014 Since Jeff Paris introduced them in the late seventies [Par78], densities turned out to be useful for studying independence results. Motivated by their simplicity and surprising strength we investigate the combinatorial complexity of two such densities which are strongly related to the pigeonhole principle.
