Deuteron photodisintegration by polarized photons in the region of the d⁎(2380)

We report the first large-acceptance measurement of the beam–spin asymmetry for deuteron photodisintegration (γ→d→pn) in the photon energy range 420...

Pt and CoB trilayer Josephson $$\pi $$ π junctions with perpendicular magnetic anisotropy

Abstract We report on the electrical transport properties of Nb based Josephson junctions with Pt/Co $$_{68}$$ 68 B $$_{32}$$ 32 /Pt ferromagnetic barriers. The barriers exhibit perpendicular magnetic anisotropy, which has the main advantag...

“The afterlife” of money. The coins found in the necropolis of Brad (Negri Commune, Bacău County)

The medieval necropolis of Brad overlaps the fortified section of the Geto-Dacian fortress of Zargidava, located on the left bank of the Siret River. Altogether, 962 graves were researched here during the years 1963-2004. The numismatic mat...

A Preliminary Study on the Efficacy of Essential Oils Against <i>Trichoderma longibrachiatum</i> Isolated from an Archival Document in Italy

In this study, a historically significant journal subject to fungal colonization was used as a case study for experimenting with a fumigation treatment using essential oils. The experiments were carried out both in vitro and in vivo directl...

Are museums the future of evolutionary medicine?

Metal Adornments of Clothing and Headwear in the Bronze Age of Western Siberia (issues of research and reconstruction) ..

The article considers issues related to the principals of scientific approach, methods and procedure of costume reconstruction on the basis of archaeological materials dating back to the Bronze Age discovered in the territory of Western Sib...

The song of air and water: Acoustic experiments with an Ecuadorian Whistle Bottle (c.900 BC–100 BC)

In Ecuador, bottles as containers for liquids appeared in the Late Formative period at the end of the Machalilla culture (1600 BC to 800 BC). Whistle bottles were created and perfected during the Chorrera culture (900 BC to 100 BC), and fin...

Deep Mapping and Spatial Anthropology

This paper provides an introduction to the Humanities Special Issue on “Deep Mapping”. It sets out the rationale for the collection and explores the broad-ranging nature of perspectives and practices that fall within the “undisciplined” int...

Numerical Simulation on Rigid Foreign Object Exclusion in the Turboprop Engine Intake System With a Bypass Duct

By considering the exclusion characteristics of foreign objects in a new intake system with a bypass duct for turboprop engines, two kinds of common rigid foreign objects, the grains, and metal pieces, are modeled based on airworthiness sta...

An Adaptive JPEG Double Compression Steganographic Scheme Based on Irregular DCT Coefficients Distribution

Steganography is to embed secret information into digital media and minimize the distortion caused by data embedding. The JPEG is a widely used image compression format, and many JPEG images transmitted on the network are double compressed....

The Numerical Solution of Fractional Parabolic Partial Integro-Differential Eequations by Gaussian and Inverse Multiquadric Radial Basis Functions

Introduction Many mathematical formulations of physical phenomena contain integro-differential equations. These equations arise in fluid dynamics, biological models, chemical kinetics, ecology, control theory of financial mathematics, aeros...

Ground calibration tests of the laser altimeter (LIDAR) for MMX mission

Abstract The spacecraft for the Japanese Martian Moon eXploration mission is equipped with a LIDAR laser altimeter. The slant range continuously measured by the LIDAR is used for the correction of the local topography and the orbit and atti...

Research Progresses of Flash Evaporation in Aerospace Applications

Liquid is overheated and evaporated quickly when it enters into the environment with lower saturation pressure than that corresponding to its initial temperature. This phenomenon is known as the flash evaporation. A natural low-pressure env...

Designing wind turbines for profitability in the day-ahead market

Traditionally, wind turbine and wind farm designs have been optimized to minimize the cost of energy. Such a design would make sense when bidding in price-based auctions. However, in a future with a high share of renewables and zero subsidi...

Research progress in high thermal conductivity of silicon carbide matrix composites reinforced with fibers

As one kind of advanced high temperature structural and functional materials, it is necessary for fiber reinforced silicon carbide matrix composites (SiC CMCs) in the field of thermal management (TM) to combine the efficient heat transfer a...

Study on Flight Performance of Propeller-Driven UAV

The engine performance test at altitudes of 0-7000 m was carried out on the high-performance test bench of the Unmanned Aerial Vehicle (UAV) piston engine. The flight performance of UAV was studied, including propeller thrust characteristic...

A Novel Inertial-Aided Star Pattern Matching Method for Distributed Multiple FoVs

An aerospace vehicle in high-speed flight involves distributed multiple fields of view (FoVs) of a star sensor, and the maneuvering of the vehicle requires inertial-aided star pattern matching. Accordingly, an inertial-aided star pattern ma...

Urban Sprawl and Changes in Land-Use Efficiency in the Beijing–Tianjin–Hebei Region, China from 2000 to 2020: A Spatiotemporal Analysis Using Earth Observation Data

Sustainable development in urban areas is at the core of the implementation of the UN 2030 Agenda and the Sustainable Development Goals (SDG). Analysis of SDG indicator 11.3.1—Land-use efficiency based on functional urban boundaries—provide...

Lie similarity analysis of MHD Casson fluid flow with heat source and variable viscosity over a porous stretching sheet

The current study presents a novel examination of heat transfer properties in a magnetohydrodynamic (MHD) flow of Casson fluid across a porous stretching sheet, uniquely incorporating the effects of heat source and variable viscosity. Unlik...

Intense laser interaction with micro-bars

Abstract Intense laser fields interact very differently with micrometric rough surfaces than with flat objects. The interaction features high laser energy absorption and increased emission of MeV electrons, ions, and of hard x-rays. In this...
