SABAT: the "Sapienza" Balloon Trajectory Simulation Code [PDF]

arXiv, 2018
We present SABAT ("Sapienza" Balloon Trajectory Simulation Code), a Fortran software for the simulation of zero-pressure scientific balloon trajectories at stratospheric altitudes. Particular attention is made to the correct reproduction of the balloon ascending phase to the floating altitude.

Durable Bio‐Based Nanocomposite Coating on Urinary Catheters Prevents Early‐Stage CAUTI‐Associated Pathogenicity

Advanced Materials Interfaces, EarlyView.
A stable bio‐based nanocomposite coating for urinary catheters is developed using a simple, environmentally‐friendly sonochemical process. The coating, integrating antimicrobial, antibiofilm, and antioxidant properties, effectively tackled multiple early‐stage pathogenic factors associated with catheter‐associated urinary tract infections.

A Bistable Assistive Device for Wireless Control of a Dysfunctional Bladder Under Minimal Stress

Advanced Materials Technologies, EarlyView.
This paper presents a wireless system designed to restore bladder function in patients with an underactive bladder (UAB). The system features a multilayered structure, combining a pre‐shaped restoration layer with a spring‐based actuator. The system delivers 95–100% voiding efficiency within a 10‐s activation while ensuring minimal stress on the ...

Automatic Comic Generation with Stylistic Multi-page Layouts and Emotion-driven Text Balloon Generation [PDF]

arXiv, 2021
In this paper, we propose a fully automatic system for generating comic books from videos without any human intervention. Given an input video along with its subtitles, our approach first extracts informative keyframes by analyzing the subtitles, and stylizes keyframes into comic-style images.

Testing Method of Stent’s Radial Force [PDF]

, 2008
In case of coronary arteriosclerosis and heart attack balloon-expandable stents are used. These balloon crimped implants are placed to the occluded vessel part and the balloons are pumped with big pressure (4-20 bar).

Heterogeneously Catalyzed Cascade Oxidative Coupling/Dearomative Spirocyclization of Diarylamines: Facile Access to Spiroacridines

Advanced Synthesis &Catalysis, EarlyView.
Abstract Spirocyclic compounds, particularly spirocyclohexadienones, are important in pharmaceuticals due to their biological activity. In this study, we develop a catalytic cascade oxidative spirocyclization of diarylamines for the rapid access to highly functionalized spirocyclohexadienones. Using commercially available recyclable heterogeneous metal
