Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots

open access: yesAdvanced Robotics Research, EarlyView.
A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Direct reactions for astrophysical p-capture rates with ORRUBA and GODDESS

open access: yesFrontiers in Physics
Understanding the nucleosynthesis and energy generation in quiescent and explosive stellar burning requires a detailed understanding of reaction rates on many unstable nuclides.

A Composite Light Curve Model of the Symbiotic Nova PU Vul (1979)

open access: yesOpen Astronomy, 2012
PU Vul (1979) is a symbiotic nova that shows a long-lasting flat optical peak followed by a slow decline. We made a quasi-evolution model for outbursts on a 0.6 M⊙ white dwarf consisting of a series of static solutions with optically-thin winds.

Textile Actuation Based on In‐Air Actuating Polypyrrole‐Based Tape Yarns for Wearable Soft Robotics: Toward On‐Body Applications

open access: yesAdvanced Robotics Research, EarlyView.
This work reports on the actuation behavior of CP‐based polypyrrole/PVdF TYs soaked in electrolyte/ionic liquids and woven actuators where such TYs are integrated. These studies are important toward the creation of on‐body applications such as wearable soft robotics, where textiles offer many advantages such as increased force, integrated electrical ...

Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

open access: yesAdvanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

Confirmation of SRGt 062340.2-265751 as a nova-like cataclysmic variable with a possible magnetic nature

open access: yesAstronomy & Astrophysics
SRGt 062340.2-265751, a cataclysmic variable identified by SRG/eROSITA thanks to its significant X-ray variability, remains poorly characterised despite the multi-wavelength follow-up.

Anti‐PD‐1 Nanobody‐Armored MSLN CAR‐T Therapy for Malignant Mesothelioma: Preclinical and Clinical Studies

open access: yesAdvanced Science, EarlyView.
A novel therapy using engineered immune cells (NAC‐T cells) showed promise for refractory malignant mesothelioma. Based on the encouraging preclinical data, the first‐in‐human trial is initiated, demonstrating tolerable safety and promising anti‐tumor activity (ORR 63.6%, DCR 100%, including one CR).

Hydrodynamic Studies of the Evolution of Recurrent, Symbiotic and Dwarf Novae: the White Dwarf Components are Growing in Mass

open access: yesOpen Astronomy, 2012
Symbiotic binaries are systems containing white dwarfs (WDs) and red giants. Symbiotic novae are those systems in which thermonuclear eruptions occur on the WD components.
