Hierarchically Rough rGO/HAp Nanocoatings on SLM Ti–6Al–4 V Implants for Enhanced Biointegration

Small, EarlyView.
This study investigates HAp/rGO bioactive coatings on Ti‐6Al‐4V fixation implants fabricated by selective laser melting with systematically varied volumetric energy density to tailor the as‐built surface state. Composite coatings were deposited by electrophoretic deposition and characterized using micro‐CT, profilometry, FESEM/EDS, and detailed XPS to ...

Reframing the Treasury Debate: Industrial Strategy and State Capacity in the UK

The Political Quarterly, EarlyView.
Abstract The Treasury has long been seen as a root cause of Britain's economic malaise, blocking much‐needed industrial intervention and embedding short‐termism. This article examines the politics of Concorde and civil nuclear power in postwar Britain to show that the Treasury was not the problem in these cases.

Comparison of Prediction Models for Sonic Boom Ground Signatures Under Realistic Flight Conditions

Aerospace
This paper presents a comparative analysis of simplified and high-fidelity sonic boom prediction methods to assess their applicability in the conceptual design of supersonic aircraft. The high-fidelity approach combines Computational Fluid Dynamics (CFD)

Falcon 9 ascent sonic boom measurements in Ventura County, California [PDF]

JASA Express Letters
Reports of audible sonic booms along the south-central California coast during SpaceX Falcon 9 launch ascents prompted measurements in Ventura County during summer 2024. A total of 132 measurements were made over six launches, with 16–25 measurements per

On the aging of sonic booms [PDF]

The Journal of the Acoustical Society of America, 1993
Sonic boom minimization exploits the shaping of nonasymptotic ‘‘mid-field’’ signatures of large aircraft [F. E. McLean, NASA TN D-2877 (1965)]. This is assisted by the ‘‘freezing’’ effect of downward propagation in the real atmosphere [W. D. Hayes and H. L. Runyan, Jr., J. Acoust. Soc. Am. 51, 695–701 (1971)]. Cleveland and Blackstock [J. Acoust.

‘Everything is a signal’: speaking circuits and noisy signs in the making of language‐oriented AI « Tout est signal » : circuits parlants et signes bruyants dans la création de l'IA orientée langage

Journal of the Royal Anthropological Institute, EarlyView.
Contemporary artificial intelligence (AI) technologies are often presumed to be capable of revealing unmediated truths about the world, including the truths language might hold, echoing the long‐standing assertion that language's primary function is to directly translate reality.

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Sonic Boom Assessment [PDF]

The Journal of the Acoustical Society of America, 1964
The difficulties of assessing the significance of sonic booms and the public's reaction to them is causing great concern. The paper describes some recent researches carried out at the University of Southampton on the relevant reactions of persons to transient sounds of the sonic-boom type, in which the various characteristics of the boom are altered ...
