Sonographic localisation of lymph nodes suspicious of metastatic breast cancer to surgical axillary levels

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 119-138, March 2025.
Sonographic imaging is used to identify the presence, number and location of malignant lymph nodes. Axillary lymph nodes suspicious of harbouring breast cancer metastasis can be localised to three surgical axillary levels. This paper will unpack the axillary anatomy, muscular sonographic landmarks, surgical axillary lymph node levels and the ...

A new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae)

Nordic Journal of Botany, EarlyView.
Revisions of herbarium collections reveal a new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae). Strophopappus comprises nine species occurring in South America, eight of which are endemic to Brazil. Currently, Vernonia riedeliana is treated as a synonym of Strophopappus bicolor.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

River Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

T‐800: An 800 Hz Data Glove for Precise Hand Gesture Tracking

SmartBot, EarlyView.
Hand motion capture provides critical insights into human dexterity and facilitates advancements in robotic manipulation, yet existing systems are limited by a trade‐off between temporal resolution and visual occlusion. Here, the authors present T‐800, a high‐bandwidth data glove achieving synchronized full‐hand motion capturing at 800 Hz.

Self‐Organized Vascularized Human Liver Spheroids: Serum‐Free Culture Conditions and Use as Tissue Building Blocks

Small, EarlyView.
This approach addresses a major challenge in tissue engineering: creating larger, vascularized tissues. Microvascular networks in liver spheroids are developed through self‐organization mediated by mesenchymal stem cells. These spheroids are maintained in serum‐reduced or serum‐free medium and serve as building blocks to form planar tissue layers ...

The Fierce Morphological Battle of Silver Nanoparticles: How Irregularities, Vacancies and Defects Tip the Crossing Sizes

Small, EarlyView.
The silver nanoparticle morphologies are identified thanks to ab initio models, including original families of defects and complex motifs, compared to measurements provided at targeted sizes (309, 561, 742, and 923 atoms). The crossings between structures to within a few atoms have been predicted due to very accurate computational conditions, which are

Alkali Chalcogenido Dialuminates A6[Al2Q6] (A = K, Rb, Cs; Q = S, Se, Te)

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Seven new alkali chalcogenido aluminates A6[Al2Q6] (A = K‐Cs, Q = S‐Te) complement the family of simple metallates(III) A6[M2Q6] (M = Al‐In, FeIII) with dinuclear anions of two edge sharing [AlQ4] tetrahedra. Despite the similar anions, straightforward bonding situation and physical properties, these metallates crystallize in seven different structure ...
