Flux Variations and Torque Reversals of Cen X-3
The Astrophysical JournalCen X-3 is an archetypical X-ray pulsar with strong flux variations and alternating torque reversals, both of which are similar to those of recently discovered pulsating ultraluminous X-ray sources.

Advanced Engineering Materials, EarlyView.Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.

News on the X-ray emission from hot subdwarf stars
Open Astronomy, 2017 In latest years, the high sensitivity of the instruments on-board the XMM-Newton and Chandra satellites allowed us to explore the properties of the X-ray emission from hot subdwarf stars.

Advanced Functional Materials, EarlyView.This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...

Very high energy cosmic gamma rays from radio and x-ray pulsars [PDF]
, 1987 This thesis is concerned with the detection of very high energy cosmic gamma-rays from isolated pulsars and X-ray binary sources using the atmospheric Cerenkov technique. A general introduction to gamma ray detection techniques is followed by adscription

Binary‐to‐Ternary Reconfigurable Transistors Using Plasma‐Assisted MoS2
Advanced Functional Materials, EarlyView.A binary‐to‐ternary reconfigurable transistor is demonstrated using a dual‐gated molybdenum disulfide homojunction with localized O2 plasma treatment. The device exhibits on/intermediate and intermediate/off current ratios of 102 and 104, respectively, and the intermediate state is electrically tunable in the ternary mode.

Stellar wind accretion and accretion disk formation: Applications to neutron star high-mass X-ray binaries [PDF]
Publications of the Astronomical Society of Japan, 2019 Abstract Recent X-ray observations have revealed the complexity and diversity of high-mass X-ray binaries (HMXBs). This diversity challenges a classical understanding of the accretion process on to the compact objects. In this study, we reinforce the conventional concept of the nature of wind-fed accretion on to a neutron star ...

Optical & X-ray Studies of Ultraluminous X-ray Sources [PDF]
, 2009 Ultraluminous X-ray Sources (ULXs) are point like X-ray sources situated external to the nucleus of their host galaxy, with inferred X-ray luminosities in excess of 10^{39} erg s^{−1} .
