Sonographic localisation of lymph nodes suspicious of metastatic breast cancer to surgical axillary levels

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 119-138, March 2025.
Sonographic imaging is used to identify the presence, number and location of malignant lymph nodes. Axillary lymph nodes suspicious of harbouring breast cancer metastasis can be localised to three surgical axillary levels. This paper will unpack the axillary anatomy, muscular sonographic landmarks, surgical axillary lymph node levels and the ...

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

Journal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Rheological Assessment of Polymer Melts and Networks: From Degradation to Recyclability

Macromolecular Rapid Communications, EarlyView.
Rheology provides a powerful analytic tool for tracking polymer degradation and structural evolution across manufacturing, service, and recycling. Linear and nonlinear rheological techniques reveal changes in molecular architecture, network stability, and processing history.

Fault Diagnosis in an Induction‐Motor‐Driven Rotating Machinery Test Rig Under Unseen Operating Loads Using Multimodal Fusion and Multiagent Deep Reinforcement Learning

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Conventional fault‐diagnosis methods, largely grounded in one‐dimensional signal analysis and linear modeling, often fail to detect complex nonlinear faults in rotating machinery operating under variable loads. Data‐driven approaches also face challenges in extracting discriminative information from high‐dimensional multisensor measurements ...

Numerical analysis of splitting without waste based on cross-wedge rolling in double rolling mechanism [PDF]

, 2013
The article presents the results of numerical analysis of splitting without waste on the basis of cross wedge rolling in double rolling mechanism. The analysed process concerns rolling the charge of V-shaped groove, and rotary bending causing the split ...

Stress-time History of Rolls with Grooves

Transactions of FAMENA, 2011
In “Steelworks Split” failures of the rolls with grooves on the 3-high-roughing mill stand occurred four times. One part of the failure analysis is an investigation of the service load and corresponding stresses. Numerical analysis of the local stresses revealed maximum stresses on the caliber 7a and on the roll neck.

Fungal‐Assisted Recycling of Carbon‐Fiber‐Reinforced Polymer Waste via Mechanistically Informed Hybrid Pathways

Polymer Composites, Volume 47, Issue 22, Page 20295-20312, 20 November 2026.
Fungal‐assisted recycling of carbon‐fibre reinforced polymer waste. ABSTRACT Epoxy‐based carbon‐fiber‐reinforced polymer (CFRP) composites are increasingly used in high‐performance applications, yet their highly cross‐linked and chemically resistant matrices remain difficult to recycle sustainably.
