The moisture content in concrete pores is a critical parameter for most of the degradation processes suffered by concrete, such as shrinkage and related cracking. objective this paper to present formulation general distribution model young-age concrete. In modeling, both cement hydration diffusion resulted humidity variations are taken into account synchronously. effect initial water (after casting) on development considered introducing time parameter. simulation reduction produced from...
Despite ongoing research efforts aimed at understanding the structural response of steel fiber reinforced concrete (SFRC), there is very limited on failure characteristics and theoretical compression-bending capacity unreinforced (SFRC without rebars, USFRC). In this study, cube compression tests, notched beam full-scale segment tests are carried out to investigate flexural performance USFRC. The crack width–bending moment curves, load–deflection ultimate load USFRC segments obtained....
Abstract Direct measurement of entanglement is an efficient method for obtaining the degree without full reconstruction quantum state. But most current direct schemes are designed states in specific physical systems, and not universal different systems. So, this paper, we want to design a algorithm two-qubit states, where means that does depend on Although conventional walk (QW) model have property, find by introducing auxiliary qubits CNOT gates circuits, generalized QW can be realized any...
This study shows that NNs do not conserve trace in quantum dissipative dynamics and proposes an uncertainty-aware approach enforces perfect conservation by design.
By extending the concept of interaction-free imaging to few-atom level, we show that asymptotically on-demand interaction- and measurement-free quantum logic gates can be realized for both single-atom single-photon qubits. The feature suppresses possibility qubit decoherence via atomic spontaneous decay, while elimination measurements significantly reduce errors arising from detector inefficiency. We present a general theory universal Zeno gates, discuss physical implementations...

In present paper, development internal relative humidity slab at an early age was investigated applying temperature combined digital sensor. experimental results show that reduced with age. general law inside can be described vapor-saturated stage 100% (Stage I) followed gradually II). length Stage I magnitude II are greatly...
Earthquake-triggered landslides (ETLs) are characterized by their extensive occurrences, having wide distributions. The conventional human–computer interaction extraction method is often time-consuming and labor-intensive, failing to meet the demands of disaster emergency response. There a pressing need for swift detection ETLs. In this study, we introduce an ETLs (MAST) combining morphological analysis edge recognition with Swin-Transformer (SWT) deep learning model, which specifically...
The magnitude 6.8 Luding earthquake that occurred on 5 September 2022, triggered multiple large-scale landslides and caused a heavy loss of life property. investigation earthquake-triggered (ETLs) facilitates disaster assessments, rescue, reconstruction, other post-disaster recovery efforts. Therefore, it is important to obtain landslide inventories in timely manner. At present, detection mainly conducted manually, which time-consuming laborious, while machine-assisted approach helps improve...
We propose a scheme for two-qubit conditional quantum Zeno phase gate semiconductor dots. The proposed system consists of two charged dots and one ancillary neutral dot driven by laser pulse tuned to the exciton resonance. primary decoherence mechanism is phonon-assisted relaxation, which can be viewed as continuous monitoring environment. Because effect, strong possibility emission sufficient strongly modify coherent dynamics, with negligible probability actual emission. solve analytically...
Aromatic oxazolines are versatile in organic synthesis as directing groups, ligands, and protected carboxylic acids. Developing efficient approaches to oxazoline from an aromatic C–H bond is more desirable compared the established protocols acid its equivalents. Herein, a simple oxazolination with broad substrate scope described. By employing this transformation enabling step, diversity-oriented of functionalized arenes target-oriented four drugs were accomplished. Mechanistic experiments...
A differential equation capable of describing the full‐slip to no‐slip friction transition along a fractured wire in parallel‐wire strand experiencing external hydrostatic pressure, by prestressed wrapping or intermittent cable bands, has been developed. The model is based on modified version previously reported theoretical work conjunction with well‐established results field contact‐stress theory. With some reasonable simplifying assumptions, closed‐form solutions have obtained that provide...
A theoretical formulation has been proposed for obtaining upper bounds to single‐layer helical strand damping under cyclic bending a constant radius of curvature. The model employs an alternative interwire/interlayer friction the traditional rigid‐plastic Coulomb model: this, then, enables one follow no‐slip‐to‐full‐slip transition over individual contact patches. Results are presented cables in which outer wires only touch core and also spiral strands with no whose just each other line...
Abstract To improve the accuracy of results rock blast damage simulation, a numerical scheme ascertaining and optimizing Riedel–Hiermaier–Thoma (RHT) model parameters was developed. First, RHT adopted to simulate limestone penetration experiments, 31 were initially determined based on published data theoretical derivation. Subsequently, sensitivity analyses conducted using “controlled variable method” optimally determine parameters. Finally, coupled smoothed-particle hydrodynamics...

Masked image modeling (MIM), which predicts randomly masked patches from unmasked ones, has emerged as a promising approach in self-supervised vision pretraining. However, the theoretical understanding of MIM is rather limited, especially with foundational architecture transformers. In this paper, to best our knowledge, we provide first end-to-end theory learning one-layer transformers softmax attention On conceptual side, posit mechanism how transformers, pretrained MIM, produce empirically...

Neural networks (NNs) accelerate simulations of quantum dissipative dynamics. Ensuring that these adhere to fundamental physical laws is crucial, but has been largely ignored in the state-of-the-art NN approaches. We show this may lead implausible results measured by violation trace conservation. To recover correct behavior, we develop physics-informed NNs mitigate violations a good extend. Beyond that, introduce an approach enforcing perfect conservation design.
