DIFFICULTIES OF DIAGNOSTICS AND CHOICE OF SURGICAL APPROACH IN PATIENTS WITH DUCTAL CHOLANGIOCARCINOMA

Вестник хирургии имени И.И. Грекова, 2017
Diagnostics and treatment of ductal cholangiocarcinoma is an actual and complicated problem of modern hepatopancreatobiliary surgery. The data of preoperative examination using modern methods weren’t always well-defined. This fact didn’t allow clinicians

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

Advanced Engineering Materials, EarlyView.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

Disentangling the effects of hydro-morphological changes on the reduction in the spawning habitat of four major Chinese carps in the Middle Yangtze River

Global Ecology and Conservation
The Middle Yangtze River serves as a critical spawning habitat for the Four Major Chinese Carps (FMCC). The operation of the Three Gorges Dam (TGD) on the Yangtze River has significantly altered flow and water temperature regimes, reduced sediment ...

Syntactic features in morphology : general problems of so-called pronominal inflection in german [PDF]

, 2009
Morphological analysis of inflectional categories has been for a long time a favored field of classical structuralism. American scholars, in this respect, concentrated on the representation of inflected forms in terms of concatenated ...

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

Advanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Basic Principle and Step-by-Step Procedure of Abdominal Hysterectomy: Part 2

The Surgery Journal, 2019
Abdominal hysterectomy is the ultimate standard operation among various gynecologic surgeries. However, the actual procedure for a patient varies substantially according to the morphological changes of the uterus and adnexa. Therefore, it is important to

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

Advanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Automation of real-time vocal tract image segmentation with SAM 2.0 and morphological operation implementation [PDF]

JASA Express Letters
Modeling articulatory representations is critical to the scientific study of speech production, including its relation to speech acoustics. However, discretizing articulatory dynamics in continuous speech has proven computationally taxing.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
