A note on the gaps between zeros of Epstein's zeta-functions on the critical line
It is proved that Epstein's zeta-function $\zeta_{Q}(s)$, related to a
positive definite integral binary quadratic form, has a zero $1/2 + i\gamma$
with $ T \leq \gamma \leq T + T^{{3/7} +\varepsilon} $ for sufficiently large
positive numbers $T$. This is an improvement of the result by M. Jutila and K.
Srinivas (Bull. London Math. Soc. 37 (2005) 45--53).

Counting squarefree discriminants of trinomials under abc
For an odd positive integer $n\ge 5$, assuming the truth of the $abc$
conjecture, we show that for a positive proportion of pairs $(a,b)$ of integers
the trinomials of the form $t^n+at+b (a,b\in \mathbb Z)$ are irreducible and
their discriminants are squarefree.

Albanese varieties of singular varieties over a perfect field
Let X be a projective variety, possibly singular. A generalized Albanese
variety of X was constructed by Esnault, Srinivas and Viehweg over
algebraically closed base field as a universal regular quotient of the relative
Chow group of 0-cycles by Levine-Weibel. In this paper, we obtain a functorial
description of the Albanese of Esnault-Srinivas-Viehweg over a perfect base
field, using duality theory of 1-motives with unipotent part.

Description of generalized Albanese varieties by curves
Let X be a projective variety over an algebraically closed base field,
possibly singular. The aim of this paper is to show that the generalized
Albanese variety of Esnault-Srinivas-Viehweg can be computed from one general
curve C in X, if the base field is of characteristic 0. We illustrate this by
an example, which we also use to unravel some mysterious properties of the
Albanese of Esnault-Srinivas-Viehweg.

Some remarks related to Maeda's conjecture
In this article we deal with the problem of counting the number of pairs of
normalized eigenforms $ (f,g) $ of weight $k$ and level $N$ such that $ a_p (f)
= a_p (g) $ where $a_p (f) $ denotes the $p-$th Fourier coefficient of $f$.
Here $p$ is a fixed prime.

Non-Wieferich primes in number fields and ABC conjecture
Let $K/\mathbb{Q}$ be an algebraic number field of class number one and
$\mathcal{O}_K$ be its ring of integers. We show that there are infinitely many
non-Wieferich primes with respect to certain units in $\mathcal{O}_K$ under the
assumption of the \textit{abc} conjecture for number fields.

A note on Euclidean cyclic cubic fields
Let $K$ be a cyclic cubic field and $\mathcal{O}_K$ be its ring of integers.
In this note we prove that all cyclic cubic number fields with conductors in
the interval $ [73, 11971]$ and with class number one are Euclidean.

A note on fierce ramification
We show that bounding ramification at infinity bounds fierce ramification.
This answers positively a question of Deligne posed to the first named author.

Shape matters: Competing mechanisms of particle shape segregation
It is well-known that granular mixtures that differ in size or shape
segregate when sheared. In the past, two mechanisms have been proposed to
describe this effect, and it is unclear if both exist. To settle this question,
we consider a bidisperse mixture of spheroids of equal volume in a rotating
drum, where the two mechanisms are predicted to act in opposite directions. We
present the first evidence that there are two \emph{distinct} segregation
mechanisms driven by relative \emph{over-stress}. Additionally, we showed that
for non-spherical particles, these two mechanisms can act in different
directions leading to a competition between the effects of the two. As a
result, the segregation intensity varies non-monotonically as a function of
$AR$, and at specific points, the segregation direction changes for both
prolate and oblate spheroids, explaining the surprising segregation reversal
previously reported. Consistent with previous results, we found that the
kinetic mechanism is dominant for (almost) spherical particles. Furthermore,
for moderate aspect ratios, the kinetic mechanism is responsible for the
spherical particles segregation to the periphery of the drum, and the gravity
mechanism plays only a minor role. Whereas, at the extreme values of $AR$, the
gravity mechanism notably increases and overtakes its kinetic counterpart.

Feature-Based TAG in place of multi-component adjunction: Computational Implications
Using feature-based Tree Adjoining Grammar (TAG), this paper presents
linguistically motivated analyses of constructions claimed to require
multi-component adjunction. These feature-based TAG analyses permit parsing of
these constructions using an existing unification-based Earley-style TAG
parser, thus obviating the need for a multi-component TAG parser without
sacrificing linguistic coverage for English.
