Transit Photometry as an Exoplanet Discovery Method

Earth and Planetary Astrophysics
Photometry with the transit method has arguably been the most successful
exoplanet discovery method to date. A short overview about the rise of that
method to its present status is given. The method's strength is the rich set of
parameters ...

Nuclear Experiment
We present a detailed study of kinematical and dynamical conditions necessary
for probing highly elusive three-nucleon short range correlations~(3N-SRCs) in
nuclei through inclusive electron scattering. The kinematic requirements that
shoul...
Internal spin resistance of spin batteries

Physics
Mesoscale and Nanoscale Physics
For spin batteries we introduce the concept of internal spin resistance which
quantifies the amount of backflow from the load to the battery. It allows to
relate through a Thevenin-Norton relation, spin current sources to spin
accumulation ...

We establish the fundamental limits of lossless analog compression by
considering the recovery of arbitrary m-dimensional real random vectors x from
the noiseless linear measurements y=Ax with n x m measurement matrix A. Our
theory is inspi...
An extended type system with lambda-typed lambda-expressions (extended
version)

Logic in Computer Science
We present the type system d, an extended type system with
lambda-typed lambda-expressions. It is related to type systems originating from
the Automath project. d extends existing lambda-typed systems by an
existential...
Strings and missing wormhole entanglement

High Energy Physics - Theory
I show that holographic calculations of entanglement entropy in the context
of AdS bulk space modified by wormhole geometries provide the expected
entanglement magnitude. This arises in the context of string theory by means of
additional ge...
Shellability of face posets of electrical networks and the CW poset

We prove a conjecture of Thomas Lam that the face posets of stratified spaces
of planar resistor networks are shellable. These posets are called uncrossing
partial orders. This shellability result combines with Lam's previous result
that th...
Explicit equations for exterior square of the general linear group

We present several explicit systems of equations defining exterior square of
the general linear group as an affine group scheme. Algebraic ingredients of
the equations, exterior numbers, are translated into the language of weight
diagrams c...

We propose a new single-winner election method ("Schulze method") and prove
that it satisfies many academic criteria (e.g. monotonicity, reversal symmetry,
resolvability, independence of clones, Condorcet criterion, k-consistency,
polynomia...

A general closed interval matrix is a matrix whose entries are closed
connected nonempty subsets of the set of the real numbers, while an interval
matrix is defined to be a matrix whose entries are closed bounded nonempty
intervals in the s...
