A Short Proof for a Lower Bound on the Zero Forcing Number

Discussiones Mathematicae Graph Theory, 2020
We provide a short proof of a conjecture of Davila and Kenter concerning a lower bound on the zero forcing number Z(G) of a graph G. More specifically, we show that Z(G) ≥ (g − 2)(δ − 2) + 2 for every graph G of girth g at least 3 and minimum degree δ at

The Relationship Between Stature and Live Weight of Dairy Cows Between Birth and Maturity

Ruminants
Lactational and reproductive performance are strongly associated with cow live weight and capacity. However, there are limited data published describing capacity (thoracic) growth and the prediction of final stature and capacity from measurements at ...

Out with the old, in with the new? A retrospective comparison of malleable erectile implants in phalloplasty

BJU International, EarlyView.
Objective To compare the long‐term outcomes of the two main types of malleable erectile implants after phalloplasty in transgender men: models originally designed for cisgender men (conventional models) or the more recently developed Zephyr Surgical Implants (Geneva, Switzerland) female‐to‐male 100 implant (ZSI FtM 100) specifically for phalloplasty ...

Understanding Rheumatoid Arthritis‐Oral Health Perceptions Around Diagnosis and the Early Disease Course: A Phenomenological Approach

Community Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives To explore how Dutch adults with rheumatoid arthritis (RA) perceive their oral health around the diagnostic process and the early disease course. The primary objective was to describe these perceptions in depth, and a secondary objective was to identify areas for future patient‐centred research.

Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

Journal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

Journal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

Convolutional cylinder-type block-circulant cycle codes [PDF]

Transactions on Combinatorics, 2013
In this paper, we consider a class of column-weight two quasi-cyclic low-density paritycheck codes in which the girth can be large enough, as an arbitrary multiple of 8. Then we devote a convolutional form to these codes, such that their generator matrix

African ape carpal morphology is not too specialized to represent the ancestral hominin carpus

Journal of Anatomy, EarlyView.
Knuckle walking is one hypothesized behavior of the Pan‐Homo last common ancestor. We analyzed carpal morphology, including Euclidean distances between behavioral pairs, to investigate whether the carpals of knuckle‐walking taxa appear relatively specialized.
