Webb telescope reveals structure of first asteroid belt found beyond our solar system
Astronomers used the powerful James Webb Space Telescope to closely image the first asteroid belt discovered beyond our solar system, which surrounds a nearby young, hot star called Fomalhaut. The dusty belts encircle Fomalhaut, which can be seen as the brightest star in the southern constellation Piscis Austrinus. The ring structure that surrounds Fomalhaut was…

Dihedral Transwing eVTOL Takes to the Skies at Larger Scale
Pterodynamics has been making waves in the electric vertical takeoff and landing (eVTOL) aircraft market with its innovative Transwing platform. And now, the company has released fresh video footage of its latest prototype. The video showcases a larger-scale version of the remarkable dihedral folding wing system that powers the Transwing. The Transwing platform uses a…

Self-Repairing Clothes Made of Fungus
Fashion is ever evolving. However, we all remember how we felt when our favorite clothes ripped or tore. Have you ever wondered what it would be like to never have to replace or repair your clothes? Thanks to a recent breakthrough by researchers from Newcastle University and Northumbria University in the UK, that dream may…

Study on the emergency capacity of coal mine enterprises in Longdong Area based on D-FAHP method
Evaluation Process According to the weight of each index determined by D-number theory and combined with Fuzzy Analytic Hierarchy Process (FAHP), the emergency capacity of a coal enterprise is evaluated. (1) Establish the evaluation factor set The evaluation index system is constructed based on the factors that affect the emergency response capacity of coal mining…

Stochastic resonance analysis of a coupled high-speed maglev vehicle-bridge coupled system under bounded noise
To explain the theoretical basis of our model’s analysis, the derivation process of the stochastic averaging method is introduced below. Consider a quasi-integrable Hamiltonian system under bounded noise excitation governed by the following equations of motion37: $$\dot{{Q}_{i}}=\frac{\partial H}{\partial {P}_{i} } \,\,\dot{{P}_{i}}=-\frac{\partial H}{\partial {Q}_{i}}-\varepsilon {c}_{ij}\frac{\partial H}{\partial {P}_{i} }+\varepsilon {h}_{ij}{\xi }_{k}\left(t\right) \,\, i,j=1,…,n;k=1,…,l$$ (1) where \({Q}_{i}\) and…

A portable immunosensor provides sensitive and rapid detection of Borrelia burgdorferi antigen in spiked blood
Borrelia burgdorferi proteins and antibodies Recombinant OspA, OspC, and VlsE of B. burgdorferi were overexpressed in pET9a/c (OspA/OspC) and pET28a (VlsE) vectors and the proteins were purified. Briefly, IPTG-induced Escherichia coli transformed with the gene of interest were grown at 37 °C, 200 rpm, in TBY (tryptone broth yeast) supplemented with 50 μg/mL kanamycin to OD600 of 1.…

Researchers propose a modeling method of the drill-string acoustic channel for downhole telemetry
Fig. 1 One-dimensional equivalence of the drill-string acoustic channel. Credit: IACAS In logging while drilling (LWD), one of the biggest challenges in upgrading from “acoustic measurement” to “intelligent guide drilling” is that the transmission rate of downhole telemetry is too low to achieve real-time and effective formation evaluation. Using drill-string… Continue Reading News Source: techxplore.com
