International Journal of Antennas and Propagation, 2020 The purpose of this paper is to investigate a large radio telescope support point number effect on its pointing accuracy and provide a useful guideline for the large radio telescope design engineer. In a large radio telescope system, the azimuth track is

Compliant Footpads Enable Terrain‐Adaptive Hopping in a Monopedal Robot
Advanced Intelligent Systems, EarlyView.A lightweight compliant footpad with embedded spines lets a monopedal hopping robot keep stable ground contact. It preserves stance‐phase dynamics and enables reliable hopping on rock, sand, and ice. Monopedal hopping robots offer exceptional mobility over discontinuous terrain but require consistent foot‐ground contact to maintain stance‐phase ...

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT
Astronomische Nachrichten, EarlyView.ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).

EBHIS Local Volume Galaxy Hi Survey (LVGHIS)
Astronomische Nachrichten, EarlyView.ABSTRACT Here, we present the “Local Volume Galaxy Hi Survey” (LVGHIS). It is based on the first data release of the Milky Way portion of the Effelsberg Bonn Hi‐Survey (EBHIS). We homogeneously measured the mass and dynamics of the local volume galaxies within the radial velocity limit of |vLSR|≤600kms−1$$ \mid {v}_{\mathrm{LSR}}\mid \le 600\kern0.6em \

The absence of women's scientific contributions in core UK pre‐university science qualifications
British Educational Research Journal, EarlyView.Abstract Despite their groundbreaking contributions to our understanding of the natural world and the universe, women's roles in biology, chemistry, physics, astronomy, environmental science and geology remain largely absent from standard educational specifications in the United Kingdom (UK), particularly at Key Stage 4 (KS4) and Key Stage 5 (KS5), or ...

Trends and Future Directions in Organic Chemistry for Drug Discovery
Chemistry – A European Journal, EarlyView.Organic synthesis is being reshaped by the convergence of catalytic innovation, automation, artificial intelligence, and emerging therapeutic modalities. Late‐stage functionalization, photoredox and electrochemical methods, biocatalysis, flow chemistry, DELs, and proximity‐based drugs are examined as components of closed‐loop discovery.
