Regular factors in regular graphs

open access: yesDiscrete Mathematics, 1993
The author shows that a \(k\)-regular \((k-1)\)-edge-connected graph with an even number of vertices has an \(m\)-factor not containing \(k-m\) arbitrarily prescribed edges whenever \(1\leq m\leq k-1\). This was known only for \(m=1\) or \(k-1\). Also the sharpness of this result and some corollaries are given.

Functional Integration of Different‐Sex Gonad Transplants Into the Adult Mouse Hypothalamic Pituitary Gonadal Axis

open access: yesAdvanced Biology, EarlyView.
This study introduces and investigates different‐sex gonad transplants in a mouse model of gender‐affirming hormone therapy. Ovaries and testes implanted into gonadectomized adults exhibit gametogenesis and steroidogenesis independent of the sex of the host.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

First‐Principles Modeling of Solid Solution Softening and Hardening Effects in Al–Mg–Zr–Si Aluminum Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...

Effects of transient, persistent, and resurgent sodium currents on excitability and spike regularity in vestibular ganglion neurons

open access: yesFrontiers in Neurology
Vestibular afferent neurons occur as two populations with differences in spike timing regularity that are independent of rate. The more excitable regular afferents have lower current thresholds and sustained spiking responses to injected currents, while ...

Single‐Crystal Castability of CM186LC Nickel‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
The optimal conditions to obtain single‐crystal (SX) castings of the directional solidification nickel‐based superalloy CM186LC, are investigated. Cylindrical samples are cast via a proprietary SX Bridgman process. The effect of solidification rates (V) ranging from 1 to 10 mm⋅min−1 on the microstructure is explored.
