Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms

Advanced Materials, EarlyView.
This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Handed Magnon Propagation in Easy‐Axis Antiferromagnetic α‐Fe2O3

Advanced Materials, EarlyView.
Coherent excitation and detection of handed magnons are achieved in the easy‐axis antiferromagnet α‐Fe2O3. An external magnetic field lifts the degeneracy between left‐ and right‐handed magnons without affecting their propagation velocity. The Dzyaloshinskii–Moriya interaction and anisotropy modulate their amplitude and damping, enabling intrinsic ...

Field‐Free, Deterministic Giant Spin‐Orbit Torque Switching of 1.3 T Perpendicular Magnetization With Symmetry‐Lifted Topological Surface States

Advanced Materials, EarlyView.
We show a giant, bias‐field free, deterministic, spin‐orbit‐torque switching of perpendicular hard magnets with HC over 1.3 T. By combining the three‐fold 3m symmetry from topological insulator surface states with the rectangular mm2 symmetry from the 2 x 1 intercalation in Cr3Te4, the interface symmetry is significantly reduced into a unidirectional m

Entre naturalisation de la montagne et patrimonialisation identitaire : l’ambivalence des représentations du Cantal dans les topoguides de randonnée

Belgeo, 2013
The present article suggests analyzing the representations of Cantal (which is a rural, low mountain range department, located in Massif Central), in various published topographical, in particular Chamina who was one of the major actors in the ...

Utilisation d'un système d'information géographique pour l'étude de la localisation des dolmens et des menhirs. Application aux monuments de la planèze de Saint-Flour (Cantal) [PDF]

, 2005
When doing some previous research work on the Auvergne megalithic monuments, we were able to show clearly that the location of dolmens and menhirs had not been, in most cases, dictated by favourable geological conditions.

Meissner Effect and Nonreciprocal Charge Transport in Non‐Topological 1T‐CrTe2/FeTe Heterostructures

Advanced Materials, EarlyView.
This work demonstrates interface‐induced superconductivity (Tc ∼12 K) with a robust Meissner effect and pronounced nonreciprocal transport in epitaxial 1T‐CrTe2/FeTe heterostructures, where 1T‐CrTe2 is a 2D ferromagnet, and FeTe is an antiferromagnetic metal.

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions

Advanced Materials, EarlyView.
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.

Dacriocistocele congênita: relato de caso e conduta

Revista Brasileira de Oftalmologia, 2014
A dacriocistocele representa uma rara anomalia congênita da região medial da órbita, causada pela obstrução distal (ao nível da válvula de Hasner) e proximal (ao nível da válvula de Rosenmüller) da via lacrimal, com subsequente dilatação do saco lacrimal.

Environmental Good Production in the Optimum Activities Portfolio of a Risk Averse Farmer [PDF]

An analytical framework is proposed for analysis of environmental good production by farmers in the case of price uncertainty. Environmental good production contracted by means of agri-environmental agreements is treated as a risk less option in the ...
