For trajectory analysis, PyFgsea supports rolling-window enrichment along pseudotime. Cells are ordered by pseudotime (e.g. diffusion pseudotime, DPT ()) computed using Scanpy (). A window of fixed size slides along the ordered cells with a user-defined step size. Trajectory termini are handled without padding, and…

The aim of this study is to thoroughly assess the informational content of the CBOE Volatility Index® (VIX® Index) in the context of various turbulent periods. The VIX Index is especially important from an investor perspective. It is often referred to as the “investor fear gauge”, because its level tends to spike…

We propose and analyse rolling-origin conformal prediction for time-series forecasting. The method calibrates the conformal quantile against the $m$ most recent pseudo-out-of-sample forecast errors, adapting to serial dependence, volatility clustering, and distributional drift that invalidate classical conformal…

We study one–day–ahead forecasting of European Union Allowance (EUA) futures by proposing an ARIMA–TX–GARCH framework that augments ARIMA with a threshold–type exogenous (TX) effect driven by the rolling correlation between EUA and Brent crude oil futures. The TX mechanism allows Brent to affect EUA differentially…

—High renewable penetration increases the frequency and magnitude of net-load ramps, stressing real-time flexibility. Two commonly deployed remedies are look-ahead economic dispatch (LAED) and ramp products (RPs), yet their operational equivalence under the industry-standard rolling-window dispatch implementation is…

Detrended fluctuation analysis alpha-1 (DFAa1) has emerged as a promising non-invasive biomarker for exercise intensity assessment. However, the standard 2-min analysis window lacks temporal resolution necessary for real-time training applications. This study systematically investigated the validity of shortened DFAa1…

Maintaining balance requires the nervous system to transform sensory signals about unexpected postural perturbations into precisely timed motor commands. Although human studies have established that postural responses unfold in distinct temporal phases, how specific kinematic variables structure these phases during…

Curved geometries are a defining feature of epithelial tissues, yet how cells integrate curvature cues across spatial scales remains unclear. Here, we combined wavy hydrogels with inducible self-rolling substrates to readily and independently impose local and large-scale curvatures on epithelial monolayers…

Understanding how sensory information is transformed along cortical hierarchies requires reliable measurement of sensory representations across areas. In vivo two-photon calcium imaging through chronic cranial windows has become an essential approach for characterizing cortical sensory representations with cellular…

Moderate leaf rolling in rice is crucial for plant architecture and stress adaptation, but its molecular regulation remains unclear. We investigated the role of RLC3/OsBLH4, a BELL-type homeobox transcription factor, in controlling leaf rolling and drought tolerance, addressing gaps in lignin biosynthesis and cell wall…

Designing energy-efficient windows requires balancing energy demand and occupant thermal comfort, particularly during early-stage design. This study presents an artificial intelligence-driven multi-objective framework for optimizing window dimensions in a simplified office building under Tehran’s hot-dry climate. A…

This paper proposes a two-step empirical framework to study the repricing of the Brazilian DI curve around Copom-related events. The empirical strategy separates the initial market reaction associated with the underlying shock from the subsequent repricing observed between the shock and the first Copom statement that…

Introduction With the growing demand for environmental sustainability and residential comfort, low-carbon buildings and healthy urban planning have become key research priorities. In summer-hot and winter-cold regions, the performance of residential building glazing plays a critical role in balancing energy efficiency…

Machine learning potentials (MLPs) can help bridge the length- and time-scale gaps required to study diverse physicochemical phenomena in nanoporous materials with ab initio accuracy. These MLPs are typically trained on quantum chemical data obtained from traditional molecular dynamics (MD) simulations that…

Smart windows that function in response to external conditions provide a promising approach to reduce heating, ventilation, and air conditioning energy consumption. However, it remains a major challenge to develop a smart window with environmental adaptability, multiple working states, and most importantly, the ability…

This paper formally defines an operational isomorphism between spectral damping in molecular vibronic systems and neuromodulatory control in biological sensory systems. Without asserting causal continuity or physical identity across scales, we show that both domains instantiate the same class of output-selective…

A ball rolled over a shallow step will experience an increase in velocity along the direction perpendicular to the step. This causes a deflection in the ball's trajectory. In this paper we derive the equations that describe the motion of a ball rolled over a shallow step and present the results of our experimental…

Longitudinal, noninvasive in vivo imaging is essential for studying brain physiology and pathological mechanisms. Advances in transcranial optical windows, including thinned-skull and optical clearing techniques, have markedly improved imaging depth and resolution when combined with multiphoton microscopy. However…
