We investigate some aspects of the problem of the estimation of birth
distributions (BD) in multi-type Galton-Watson trees (MGW) with unobserved
types. More precisely, we consider two-type MGW called spinal-structured trees.
This kind of tr...
Instanton Floer homology, sutures, and Euler characteristics

This is a companion paper to an earlier work of the authors. In this paper,
we provide an axiomatic definition of Floer homology for balanced sutured
manifolds and prove that the graded Euler characteristic χgr of
this homology ...

In this paper, we consider some metric-affine Myrzakulov gravity (MG)
theories with Gauss-Bonnet scalars. Also we consider the MG theories with the
boundary term scalars. Note that these MG theories with the Gauss-Bonnet and
boundary term s...

A Latent Variable Model for Relational Events with Multiple Receivers
January 13, 2021

Statistics
Methodology
Directional relational event data, such as email data, often contain unicast
messages (i.e., messages of one sender towards one receiver) and multicast
messages (i.e., messages of one sender towards multiple receivers). The Enron
email data...

High Energy Physics - Phenomenology
In the case of two-generation Majorana neutrinos, we derive the oscillation
probabilities for ν↔ν, νc↔νc, and
ν↔νc within a unified framework using a relativistic
equation...

In green plants, chlorophyll-a and chlorophyll-b are the predominant pigments
bound to light-harvesting proteins. While the individual characteristics of
these chlorophylls are well understood, the advantages of their coexistence
remain unc...
Algorithms for optimal control of hybrid systems with sliding motion

Mathematics
Optimization and Control
This paper concerns two algorithms for solving optimal control problems with
hybrid systems. The first algorithm aims at hybrid systems exhibiting sliding
modes. The first algorithm has several features which distinguishes it from the
other...

We investigate the enumeration of query results for an important subset of
CQs with projections, namely star and path queries. The task is to design data
structures and algorithms that allow for efficient enumeration with delay
