Bohmian Trajectories For a Time Foliation with Kinks

open access: yes, 2013
This paper concerns the hypersurface Bohm–Dirac model, i.e., the version of Bohmian mechanics in a relativistic space-time proposed by Dürr et al. [1], which assumes a preferred foliation of space-time into spacelike hypersurfaces (called the time ...

Geology of amethyst quartz deposits from Montezuma and surrounding areas of Minas Gerais and Bahia States

open access: yesGeologia USP. Série Científica, 2023
Amethyst quartz deposits occur in some regions of Minas Gerais state, Brazil, related to different geological environments. The most important are associated with hydrothermal veins crossing the Espinhaço mountain range, mainly in small and eroded ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

A series of Nash resolutions of a singular foliation [PDF]

open access: yes
We construct a series of blowups $(\widetilde M_i,π_i)_{i\in \mathbb N_0}$ of a singular foliation by applying to the universal Lie $\infty$-algebroid of a singular foliation the so-called Nash modification.

Anisotropy-Driven Failure Mechanisms in Deep Mining: Integrated Geomechanical Analysis of the Draa Sfar Polymetallic Mine (Morocco)

open access: yesApplied Sciences
The Draa Sfar polymetallic mine, located near Marrakech in Morocco, represents the deepest currently operating underground mine in North Africa, with workings extending beyond depths of −1200 m. At such depths, mining activities are conducted within weak,

Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

open access: yesAdvanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

A Review of Rock Mass Anisotropy in Underground Mining: Characterisation, Modelling, and Monitoring

open access: yesGeotechnics
Anisotropy is a first-order control on rock mass behaviour in foliated, veined, and fabric-controlled ground, yet it remains underrepresented in routine geotechnical practice.

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

open access: yesAdvanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

Spatially Regulated Lithium Plating via Li2O‐Rich Interphase Enables Durable Fast‐Charging Hybrid Lithium Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...
