In the context of Ciphertext-Policy Attribute-Based Encryption (CP-ABE), if a decryption device associated with an attribute set S_D appears on eBay, and is alleged to be able decrypt any ciphertexts policies satisfied by S_D, no one including CP-ABE authorities can identify malicious user(s) who build such using their key(s). This has been known as major practicality concern in applications, for example, providing fine-grained access control encrypted data. Due nature CP-ABE, users get keys...

Abstract As cancer is increasingly considered a metabolic disorder, it postulated that serum metabolite profiling can be viable approach for detecting the presence of cancer. By multiplexing mass spectrometry fingerprints from two independent nanostructured matrixes through machine learning highly sensitive detection and high throughput analysis, we report laser desorption/ionization (LDI) spectrometry-based liquid biopsy pan-cancer screening classification. The M ultiplexed N anomaterial- A...

Bias in Foundation Models (FMs) - trained on vast datasets spanning societal and historical knowledge poses significant challenges for fairness equity across fields such as healthcare, education, finance. These biases, rooted the overrepresentation of stereotypes inequalities training data, exacerbate real-world discrimination, reinforce harmful stereotypes, erode trust AI systems. To address this, we introduce Trident Probe Testing (TriProTesting), a systematic testing method that detects...

The intricate vibration of a working vehicle provides an important signature to the type. Small vibrations introduce phase modulation in radar echoes, which is referred as micro-Doppler (m-D) phenomenon and can be modeled sinusoidal frequency-modulated (SFM) signal. Such induced by consists multiple frequency components; moreover, usually rather weak. Present parametric estimators are difficult estimate so many parameters every component, while nonparametric approaches suffer from low...

Synthesis of geopolymer using metakaolin (MK) usually requires a relatively high curing temperature, which limits the application MK-based geopolymers in practice civil engineering. With goal developing cementitious composite that can be cured at room present study, ground granulated blast furnace slag powder was incorporated into MK for synthesis geopolymer. aid compressive strength tests, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and scanning electron...

When a highway tunnel intersects fault fracture zone, the excavation process disrupts surrounding weak and fragmented rock mass, compromising stability of zone. This study compares deformation stress distribution using reserved core soil method, central diaphragm (CD) cross (CRD) method during through zones. Among these, CRD is identified as safest construction technique. Additionally, to address significant when tunneling zones, impact various pre-support advance reinforcement techniques on...

The ground motion in the near-fault region of an earthquake is characterized by exceptional energy levels, powerful velocity impulses, substantial spatial variability, and notable permanent displacement. These unique attributes can dramatically escalate structural damage. Steel truss arch bridges, being critical components transportation networks, are particularly vulnerable to these phenomena due their extensive stiffness spans. Such factors difficult accurately simulate. In this study,...

The queueing model known as precedence-based discipline , proposed in [8] by Tsitsiklis et al. is addressed. In this model, there are infinitely many servers and for any pair of customers i j such that arrived later than j, a fixed probability p will have to wait the end execution before starting its execution. case where customer service times deterministic arrival process Poisson, these authors derived stability condition which determines maximum rate keeps system stable. For more general...

This paper focuses on the impact of wave passage effect long-span bridge. In order to make more obvious, ground motion samples are selected from near-fault 1999 Chi-Chi earthquake and an arch bridge with a 280m main span is as sample. The divided into two groups according characteristics near-fault. A sequence fragility curves developed. It shown that seismic damage increased by increase obvious in motion.

Abstract Attribute-based encryption (ABE) is a versatile one-to-many primitive, which enables fine-grained access control over encrypted data. Due to its promising applications in practice, ABE schemes with high efficiency, security and expressivity have been continuously emerging. On the other hand, due nature of ABE, malicious user may abuse decryption privilege. Therefore, being able identify such crucial towards practicality ABE. Although some specific literature enjoys tracing function,...
