Ultrathin Flexible Pressure Sensors Junshan Liu and co-workers develop an ultra-thin, ultra-flexible, ultra-light, ultra-sensitive pressure sensor via the innovative nanoengineering strategy, showing potential to promote fields of flexible electronics wearable devices. More details can be found in article number 2208015.

A new indexing method is presented which is capable of indexing multiple crystal lattices from narrow wedges of diffraction data. The method takes advantage of a simplification of Fourier transform-based methods that is applicable when the unit-cell dimensions are known a priori. The efficacy of this method is demonstrated with both semi-synthetic multi-lattice data and real multi-lattice data ...

We study the self-duality operator on conic 4-manifolds. The self-duality operator can be identified as a regular singular operator in the sense of Brüning and Seeley, based on which we construct its parametrizations and closed extensions. We also compute the indexes.

Epidermal sensors and electronics represent a class of artificial devices whose thickness, mass density, and mechanical stiffness are well-matched with human epidermis. They can be applied as temporary transfer tattoos on the surface of any part of human body for physiological measurements, electrical or thermal stimulation, as well as wireless communications. Except for comfort and wearability...

T he management of patients who suffer blunt aortic injury (BAI) has drastically changed since the approval of stent grafts to treat aortic disease. At most major trauma centers, thoracic endovascular aortic repair (TEVAR) has now become the treatment of choice.1 With the recent approval of the Conformable GORE® TAG® Device (Gore & Associates, Flagstaff, AZ) for isolated lesions, BAI is now an ...

Nowhere is this truer than in the realm of wound care, where treatment choice can have a serious effect on healing and nurses often have to make ‘on-the-spot’ decisions (Hallett et al, 2000). Whereas the inpatient nurse may have access to onsite infection control teams, tissue viability specialist nurses, link nurses and various medical specialties such as vascular, plastic surgery, surgical, e...

Electrostatic clutching offers lightweight, energy-efficient, and fast controllable force transmission for exoskeletons and walking robots. Clutching is achieved by charging two electrically-conductive clutch plates with micrometerscale thickness separated by a thin dielectric insulating layer. Because the clutch acts like a capacitor, power is only required while changing states, not to mainta...

The conformability of angular observales (angular momentum and azimuthal angle) with the mathematical rules of quantum mechanics is a question which still rouses debates. It is valued negatively within the existing approaches which are restricted by two amendable presumptions. If the respective presumptions are removed one can obtain a general approach in which the mentioned question is valued ...
