The pre-telescopic observations of the Moon in early seventeenth-century London: The case of Edward Gresham (1565–1613)

Notes and Records: the Royal Society journal of the history of science, 2019
This article supplements the history of the pre-telescopic observations of the Moon at the turn of the seventeenth century with an analysis of the hitherto understudied manuscript Astrostereon or the Discourse of the Falling of the Planet (1603), written

Self‐Aligned Heterojunction Gate Carbon Nanotube Phototransistors for Highly Sensitive Infrared Detection

Advanced Electronic Materials, EarlyView.
This paper presents a self‐aligned heterojunction gate phototransistor that eliminates the need for high‐precision alignment tools. The device achieves a high responsivity of 2.9 × 105 A W−1 and a specific detectivity of 9.6 × 1013 Jones, comparable to the performance of non‐self‐aligned devices requiring complex fabrication.

Comparative Evaluation of HFC‐134a Decompositions Over Metal‐Impregnated γ‐Al2O3 Catalysts (M/γ‐Al2O3) (M = Mg, Ni, Co, Zn, Cu)

Advanced Energy and Sustainability Research, EarlyView.
This study examines the impact of an impregnated metalon the structural alterations of the catalyst induced by intermediatesgenerated during the HFC‐134a catalytic decomposition reaction. Through adetailed analysis of the catalyst before and after the reaction, the underlyingcause of the observed inactivity is elucidated.

Improved Orthorectification and Empirical Reduction of Topographic Effects in Monostatic Mini-RF S-band Observations of the Moon

The Planetary Science Journal
The Miniature Radio Frequency instrument (Mini-RF) on the Lunar Reconnaissance Orbiter obtained widespread synthetic aperture radar observations of the Moon in the S band (12.6 cm), including nearly complete coverage at both lunar poles.

Surgical and Oncological Outcomes of Conversion Surgery After Hepatic Arterial Infusion Chemotherapy for Initially Unresectable Locally Advanced Hepatocellular Carcinoma

Annals of Gastroenterological Surgery, EarlyView.
Conversion surgery for HCC. ABSTRACT Background Since 2013, we have performed conversion surgery after hepatic arterial infusion chemotherapy (HAIC) for initially unresectable locally advanced hepatocellular carcinoma (LA‐HCC). Methods Between 2013 and 2021, we assessed the surgical and oncological outcomes and pathological findings of patients with LA‐
