Surgical Outcomes and Recurrence Management in Borderline Resectable Hepatocellular Carcinoma: Implications for Multidisciplinary Strategies

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Multivariate analysis identified that up‐to‐7 out (p < 0.001), lymph node metastasis (p < 0.001), and non‐anatomical resection (p = 0.02) were independent predictors of cancer recurrence, while older age (p = 0.01), Child‐Pugh B (p < 0.001), up‐to‐7 out (p = 0.01), macrovascular invasion (p = 0.01), and lymph node metastasis (p < 0.001) were ...

Modeling the exchange rate using price levels and country risk

open access: yesCogent Economics & Finance, 2015
This paper builds two factor discrete time models in order to investigate the effect of sovereign risk on the nominal exchange rates in a Markov switching framework. The empirical section of the paper uses seven currencies from Chile, the Czech Republic,

Automated generative process synthesis via transformer‐based dual‐loop simulation and optimization

open access: yesAIChE Journal, EarlyView.
Abstract This study presents a novel framework for automated generative process synthesis, addressing the complexity of simultaneously optimizing discrete topologies and continuous operating variables. To overcome conventional superstructure limitations, we propose a dual‐loop architecture integrating generative transformers with rigorous process ...

Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

open access: yesAdvanced Intelligent Systems, EarlyView.
Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

Electroencephalogram‐Driven Recognition of Parkinson's Disease Through a Mycelium‐Inspired Memristive Reservoir Computing Circuit

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a bio‐inspired computing framework for Parkinson's disease analog recognition using electroencephalogram signals. Temporally encoded EEG features stimulate a mycelium‐inspired memristive reservoir, where disease‐related patterns emerge through physical spatiotemporal dynamics.

Sovereign Credit Rating Contagion in the EU

open access: yesProcedia Economics and Finance, 2015
AbstractThe recent persistent and synchronised deterioration in the euro zone had severe consequences for the euro community, the effects of which have been felt by the global community. This study proved that sovereign rating contagion existed between euro countries during the two recent windows of crises, namely the Lehman and sovereign debt crisis ...

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

open access: yesAdvanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Sovereign Credit Rating, Rating Migration, and the Risk-Free Rate: A Joint Markov Process and Random Walk Modelling of the Risk-Free Rate

open access: yesExpert Journal of Economics, 2019
The study proposes and tests a risk-free rate model that simultaneously lets the risk-free rate migrate between rating categories as risk-free rate ranges, and follow a random walk within rating categories as risk-free rate ranges.

Modelling the role of credit rating agencies : Do they spark off a virtuous circle? [PDF]

open access: yes, 2005
In this paper, we propose a model of credit rating agencies using the global games framework to incorporate information and coordination problems.
