Hmm… maybe I should pickup a watch with a "California Dial". 🤔
P.S. For those unfamiliar with this dial layout or even those who have seen it but wondered WTF is going on, this is a nice summary:

With its mix of Roman and Arabic numerals, the so-called California dial has become one of the most sought-after Rolex watches of the modern era.

Modelling of Counter-Current Gas-Liquid Annular Flow in a Vertical Annulus
Annular two-phase flow involving upward-moving gas and downward-flowing liquid within a vertical annular geometry is a common configuration in various engineering systems. In such systems, accurately predicting the pressure gradient is essential for understanding flow stability, equipment performance, and system design under counter-current conditions. This paper presents a general mechanistic model to predict the pressure gradient in counter-current annular flow within a vertical annular space…

Measurement of Downward-going Milli-charged particles beyond GZK cutoff at the Pierre Auger Observatory
It is assumed that superheavy dark matter particles (SHDM, $ϕ$) with $\mathcal{O}$(ZeV) mass may decay to relativistic milli-charged particles (MCPs, $χ$) via a channel $ϕ\toχ\barχ$ or $γχ\barχ$. The downward-going MCPs passing through the atmosphere can be measured by the Pierre Auger observatory (Auger). The massless hidden photon model is taken for MCPs to interact with nuclei, so that we evaluated the numbers and fluxes of expected MCPs at Auger assuming 14 years of Auger data. The …

Joint Routing and Control Optimization in VANET
In this paper, we introduce DynaRoute, an adaptive joint optimization framework for dynamic vehicular networks that simultaneously addresses platoon control and data transmission through trajectory-aware routing and safety-constrained vehicle coordination. DynaRoute guarantees continuous vehicle movement via platoon safety control with optimizing transmission paths through real-time trajectory prediction and ensuring reliable data. Our solution achieves three key objectives: (1) maintaining pla…

The bunkbed conjecture still holds for cactus graphs and for graphs with certain biconnected components
Recently, the bunkbed conjecture has been shown to be false, which naturally prompts questions on how to classify the graphs that still satisfy the conjecture. We distinguish between a weak version of the bunkbed conjecture where all the horizontal edges of the bunkbed graph are present with the same probability and a strong version of the conjecture where the edge weights on the underlying graph may be assigned individually. We show that any given graph satisfies either version of the conjectu…

My fine "new" (2023) bike is in the shop, so I unmothballed my trusty classic steed for today's ride. After a go with the tire pump, I was off like the wind. There's something exquisite about a strong and simple piece of engineering. That old bike is 39 years old! I bought it new back in California in the day. It's still a sweet ride.

Attention-based Learning for 3D Informative Path Planning
In this work, we propose an attention-based deep reinforcement learning approach to address the adaptive informative path planning (IPP) problem in 3D space, where an aerial robot equipped with a downward-facing sensor must dynamically adjust its 3D position to balance sensing footprint and accuracy, and finally obtain a high-quality belief of an underlying field of interest over a given domain (e.g., presence of specific plants, hazardous gas, geological structures, etc.). In adaptive IPP task…
