The virtual contributions from $K^*$ in the $B \to K^*πh$ and $B \to Kρh$ decays
Inspired by the significant virtual contributions of the subprocesses $D^{*}/B^{*}\to Dπ$ and $ ρ\toωπ/K\bar{K}$ in the three-body hadronic $B$ meson decays, we study the off-shell effects of the resonance $K^*$ decaying into the $K^*π$ or $Kρ$ system in the decays $B \to K^*πh$ and $B \to Kρh$ (with $h=π, K$) within the perturbative QCD approach. The strong coupling constants $g_{K^*K^*π}$ and $g_{K^*Kρ}$ involved in this work are derived from the coupling constant $g_{ρωπ}$ unde…

Data-Driven Energy Estimation for Virtual Servers Using Combined System Metrics and Machine Learning
This paper presents a machine learning-based approach to estimate the energy consumption of virtual servers without access to physical power measurement interfaces. Using resource utilization metrics collected from guest virtual machines, we train a Gradient Boosting Regressor to predict energy consumption measured via RAPL on the host. We demonstrate, for the first time, guest-only resource-based energy estimation without privileged host access with experiments across diverse workloads, achiev…

Virtual Agent Economies
The rapid adoption of autonomous AI agents is giving rise to a new economic layer where agents transact and coordinate at scales and speeds beyond direct human oversight. We propose the "sandbox economy" as a framework for analyzing this emergent system, characterizing it along two key dimensions: its origins (emergent vs. intentional) and its degree of separateness from the established human economy (permeable vs. impermeable). Our current trajectory points toward a spontaneous emergence of a …

We propose a fully mixed virtual element method for the numerical approximation of the coupling between stress-altered diffusion and linear elasticity equations with strong symmetry of total poroelastic stress (using the Hellinger--Reissner principle).

Virtual Poincare polynomial of moduli space of semistable sheaves of rank two on reducible curves
The main purpose of this paper is to give an explicit description of the moduli space of semistable sheaves of rank two on a stable curve C obtained by gluing two smooth curves at a point. We prove that the moduli space is irreducible and birational to a projective bundle over the moduli space of stable vector bundles on each component curve, independently of the choice of polarization. As an application, we compute the virtual Poincare polynomial of the moduli space.

The reason is the inherent link between the fakeonic system and the parent higher-derivative local system: …

Efficiently Computing Equilibria in Budget-Aggregation Games
Budget aggregation deals with the social choice problem of distributing an exogenously given budget among a set of public projects, given agents' preferences. Taking a game-theoretic perspective, we initialize the study of \emph{budget-aggregation games} where each agent has virtual decision power over some fraction of the budget. This paper investigates the structure and shows efficient computability of Nash equilibria in this setting for various preference models. In particular, we show that …

A virtual five element basis for the uncountable linear orders
We prove that for every Aronzsajn line A and every Countryman line C, there is a proper forcing extension in which A contains an isomorphic copy of either C or its converse C*. As a corollary, we obtain answers to several related questions asked by the second author in the literature: if there is an inaccessible cardinal, then there is a proper forcing extension in which the uncountable linear orders have a five element basis; BPFA implies the existence of a five element basis for the uncountab…

Comparing Methods for the Cross-Level Verification of SystemC Peripherals with Symbolic Execution
Virtual Prototypes (VPs) are important tools in modern hardware development. At high abstractions, they are often implemented in SystemC and offer early analysis of increasingly complex designs. These complex designs often combine one or more processors, interconnects, and peripherals to perform tasks in hardware or interact with the environment. Verifying these subsystems is a well-suited task for VPs, as they allow reasoning across different abstraction levels. While modern verification techn…

Planar Juggling of a Devil-Stick using Discrete VHCs
Planar juggling of a devil-stick using impulsive inputs is addressed using the concept of discrete virtual holonomic constraints (DVHC). The location of the center-of-mass of the devil-stick is specified in terms of its orientation at the discrete instants when impulsive control inputs are applied. The discrete zero dynamics (DZD) resulting from the choice of DVHC provides conditions for stable juggling. A control design that enforces the DVHC and an orbit stabilizing controller are presented. …

Improving Facial Rig Semantics for Tracking and Retargeting
In this paper, we consider retargeting a tracked facial performance to either another person or to a virtual character in a game or virtual reality (VR) environment. We remove the difficulties associated with identifying and retargeting the semantics of one rig framework to another by utilizing the same framework (3DMM, FLAME, MetaHuman, etc.) for both subjects. Although this does not constrain the choice of framework when retargeting from one person to another, it does force the tracker to use…

Virtual staining for 3D X-ray histology of bone implants
Three-dimensional X-ray histology techniques offer a non-invasive alternative to conventional 2D histology, enabling volumetric imaging of biological tissues without the need for physical sectioning or chemical staining. However, the inherent greyscale image contrast of X-ray tomography limits its biochemical specificity compared to traditional histological stains. Within digital pathology, deep learning-based virtual staining has demonstrated utility in simulating stained appearances from labe…

Direction of Arrival Estimation with Virtual Antenna Array Using FMCW Radar Simulated Data
The FMCW radars are widely used for automotive radar systems. The basic idea for FMCW radars is to generate a linear frequency ramp as transmit signal. The difference frequency, (i.e., beat frequency) between the transmitted and received signal is determined after down conversion. The FFT operation on beat frequency signal can recognize targets at different range and velocity. Increasing demand on safety functionality leads to the Direction of Arrival (DOA) estimation to resolve two closely loc…

Isospin symmetry breaking and gluon anomaly
Isospin violating effects, both due to the nonvanishing quark mass difference $m_d-m_u$ and to virtual photons, are studied by fitting the squared masses of pseudoscalar mesons to the second order in the simultaneous expansion in powers of $1/N_c$, momenta and quark masses. It is shown that the gluon anomaly enhances the contribution of virtual photons and, thus, promotes to an additional (to the well-known current algebra result of Gross, Treiman and Wilczek) dynamical restoration of isospin s…

Natural head rotation is critical for believable embodied virtual agents, yet this micro-level behavior remains largely underexplored.

This yields agents that look at conspicuous objects while overlooking obstacles or task-relevant cues, diminishing realism in a virtual environment. We introduce SCOR…

Although such events are increasingly conducted, research on them remains fragmented, with limited integration between hackathon studies and hybrid collaboration. Existing strategies for in-person or online-only events often fail to address the unique challenges of hybrid formats, such as managing communication across physical and virtual spaces. Our work addresses thi…

The Interplay of Attention and Memory in Visual Enumeration
Humans navigate and understand complex visual environments by subconsciously quantifying what they see, a process known as visual enumeration. However, traditional studies using flat screens fail to capture the cognitive dynamics of this process over the large visual fields of real-world scenes. To address this gap, we developed an immersive virtual reality system with integrated eye-tracking to investigate the interplay between attention and memory during complex enumeration. We conducted a tw…
