Multimode piezoelectric shunt damping of thin plates with arrays of separately shunted patches, method, and experimental validation [PDF]
arXiv, 2021 Two-dimensional thin plates are widely used in many applications. Shunt damping is a promising way for the attenuation of vibration of these electromechanical systems. It enables a compact vibration damping method without adding significant mass and volumetric occupancy. Analyzing the dynamics of such electromechanical systems requires precise modeling

International Journal of Gastrointestinal InterventionPortal hypertension, a known complication of liver cirrhosis, typically leads to variceal bleeding in the esophagus and stomach. However, ectopic varices can also occur outside the gastroesophageal region and may present with life-threatening massive ...

Leveraging weak complementary labels to improve semantic segmentation of hepatocellular carcinoma and cholangiocarcinoma in H&E-stained slides [PDF]
arXiv, 2023 In this paper, we present a deep learning segmentation approach to classify and quantify the two most prevalent primary liver cancers - hepatocellular carcinoma and intrahepatic cholangiocarcinoma - from hematoxylin and eosin (H&E) stained whole slide images.

Controlling hysteresis in superconducting constrictions with a resistive shunt [PDF]
Fast Track Communications in Supercond. Sci. Technol. 28 (2015)
072003, 2015 We demonstrate control of the thermal hysteresis in superconducting constrictions by adding a resistive shunt. In order to prevent thermal relaxation oscillations, the shunt resistor is placed in close vicinity of the constriction, making the inductive current-switching time smaller than the thermal equilibration time.

Semi-shunt field emission in electronic devices [PDF]
, 2014 We introduce a concept of semi-shunts representing needle shaped metallic protrusions shorter than the distance between a device electrodes. Due to the lightening rod type of field enhancement, they induce strong electron emission. We consider the corresponding signature effects in photovoltaic applications; they are: low open circuit voltages and ...

A Polarization and Radiomics Feature Fusion Network for the Classification of Hepatocellular Carcinoma and Intrahepatic Cholangiocarcinoma [PDF]
arXiv, 2023 Classifying hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) is a critical step in treatment selection and prognosis evaluation for patients with liver diseases. Traditional histopathological diagnosis poses challenges in this context.

Charging effects in the inductively shunted Josephson junction [PDF]
Phys. Rev. Lett. 103, 217004 (2009), 2009 The choice of impedance used to shunt a Josephson junction determines if the charge transferred through the circuit is quantized: a capacitive shunt renders the charge discrete, whereas an inductive shunt leads to continuous charge. This discrepancy leads to a paradox in the limit of large inductances L.

Journal of the American College of Surgeons, 2012 Widespread application of transjugular intrahepatic portasystemic shunt (TIPS) continues despite the lack of trials documenting efficacy superior to surgical shunting. Here we present an 18-year follow-up of a prospective randomized trial comparing TIPS with small-diameter prosthetic H-graft portacaval shunt (HGPCS) for portal decompression.Beginning ...

Dynamics of superconducting nanowires shunted with an external resistor [PDF]
Phys. Rev. B 85, 224507 (2012), 2012 We present the first study of superconducting nanowires shunted with an external resistor, geared towards understanding and controlling coherence and dissipation in nanowires. The dynamics is probed by measuring the evolution of the V-I characteristics and the distributions of switching and retrapping currents upon varying the shunt resistor and ...
