A FAN BEAM MODEL FOR RADIO PULSARS. I. OBSERVATIONAL EVIDENCE [PDF]
, 2014 We propose a novel beam model for radio pulsars based on the scenario that the broadband and coherent emission from secondary relativistic particles, as they move along a flux tube in a dipolar magnetic field, form a radially extended sub-beam with ...

Advanced Materials, Volume 37, Issue 20, May 19, 2025.Stem cell spheroids, produced via a high‐throughput microfabrication technique, are transported within a vortex generated at the outlet channels of a cross‐slot millifluidic chip. For Reynolds number exceeding 170–200, intermittent high shear stresses applied to each spheroid within the vortex trigger a massive release of biologically active ...

Pulsar-candidate Selection Using a Generative Adversarial Network and ResNeXt
The Astrophysical Journal Supplement Series, 2022 Pulsar research has been a hot topic in the area of astronomy since they were first discovered. Pulsar discovery is fundamental for pulsar research. While pulsars are now visible across the electromagnetic spectrum, pulsar searches with modern radio ...

A Cosmic Census of Radio Pulsars with the SKA [PDF]
, 2014 The Square Kilometre Array (SKA) will make ground breaking discoveries in pulsar science. In this chapter we outline the SKA surveys for new pulsars, as well as how we will perform the necessary follow-up timing observations. The SKA's wide field-of-view,

Systems Engineering Methodology for Digital Supply Chain Business Models
Systems Engineering, Volume 28, Issue 3, Page 411-437, May 2025.ABSTRACT Globalization and growing business dynamics lead to weakly harmonized supply chain (SC) systems. While smart technology offers innovation opportunities, supply chains often lack the integration needed to fully leverage resources and collaboration.

The Emission Geometry of Pulsars with Interpulses
The Astrophysical JournalWe present polarization profiles of 23 pulsars exhibiting interpulse (IP) emissions using the Five-hundred-meter Aperture Spherical Radio Telescope. By applying the rotating vector model (RVM), we measured the inclination and impact angles for 16 pulsars,

Testing Relativistic Gravity with Radio Pulsars [PDF]
, 2014 Before the 1970s, precision tests for gravity theories were constrained to the weak gravitational fields of the Solar system. Hence, only the weak-field slow-motion aspects of relativistic celestial mechanics could be investigated. Testing gravity beyond

Pancreatic Cancer: Pathogenesis and Clinical Studies
MedComm, Volume 6, Issue 4, April 2025.Although the treatment landscape for cancer has evolved rapidly in recent years, progress has stagnated for pancreatic cancer (PC). PC includes multiple types, but pancreatic ductal adenocarcinoma (PDAC) accounts for >90% of cases. This review focuses on the molecular pathogenesis and different treatments for PDAC, hoping to propose future directions ...

RADIO-QUIET AND RADIO-LOUD PULSARS: SIMILAR IN GAMMA-RAYS BUT DIFFERENT IN X-RAYS [PDF]
, 2015 We present new Chandra and XMM-Newton observations of a sample of eight radio-quiet (RQ) γ-ray pulsars detected by the Fermi Large Area Telescope. For all eight pulsars we identify the X-ray counterpart, based on the X-ray source localization and the ...
