Pointwise completeness and pointwise degeneracy of fractional descriptor continuous-time linear systems with regular pencils

open access: yesBulletin of the Polish Academy of Sciences Technical Sciences, 2015
Abstract Pointwise completeness and pointwise degeneracy of the fractional descriptor continuous-time linear systems with regular pencils are addressed. Conditions for the pointwise completeness and pointwise degeneracy of the systems are established and illustrated by an example.

From a Probabilistic PBEE Framework to Risk‐Targeted Structural Design With Cascading Hazards: Engineering Application for Seismic–Radiological Safety

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Earthquake‐induced damage of structures can trigger cascading hazards, linking structural performance to nonstructural consequences. In current engineering practice, these two aspects are typically addressed separately, limiting the ability to account for such coupled effects in design.

Analytical Framework for System‐Level Fragility Surfaces of Reinforced Concrete Bridges Under Mainshock‐Aftershock Sequences

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Conventional single intensity measure (IM) fragility approaches with simplified component dependency assumptions overlook the progressive damage accumulation and evolving inter‐component correlations that govern system behavior under mainshock‐aftershock (MSAS) loading.

Hybrid Temporal Autoencoder and Similarity Matching for Low Aggregation Level Long Time Series Forecasting

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Deep learning‐based long time series forecasting (LTSF) has achieved high accuracy by effectively capturing the underlying trends, seasonality, and temporal dependencies within time series data. However, at the individual entity level, termed the low aggregation level (LAL), intermittency, irregularity, and data sparsity undermine the ...

Longitudinal associations between sleepiness and sleep disturbances across pregnancy

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Although sleep disturbances increase during pregnancy, sleepiness does not appear to follow a similar trajectory. Given that the relationship between sleep disturbances and sleepiness during pregnancy is understudied, we examined their associations to determine whether these relationships strengthen with advancing gestation.

Identifying Peer Effects in Networks with Unobserved Effort and Isolated Students

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT Peer influence on effort devoted to some activity is often studied when effort is unobserved, and the researcher instead observes an outcome that combines effort with other shocks. For instance, in education, achievement measures such as GPA reflect both effort and idiosyncratic GPA shocks.

Tracking Summer Greenland Blocking: The Upstream Pathway Shapes Historical Extremes and Future Change

open access: yesInternational Journal of Climatology, EarlyView.
This study investigates summer Greenland atmospheric blocking using the Lagrangian tracking Python package blocktrack applied to ERA5 reanalysis and CMIP6 models. Two types of blocks—upstream (Northern Canada origin) and retrograding (Northern Atlantic origin)—are distinguished, with upstream blocks driving recent observed frequency increasing trends ...

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Multimodal Neoadjuvant Therapy for Pancreatic Ductal Adenocarcinoma (PDAC) With Vascular Involvement: What Is the Impact of Radiation on Perioperative Outcomes, Local Control, and Survival?

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Objectives Neoadjuvant chemoradiation for PDAC with vascular invasion remains understudied. The aim of this study is to compare neoadjuvant chemotherapy with chemoradiation (NAC + CRT) versus neoadjuvant chemotherapy (NAC) for PDAC with vascular involvement.
