Avaliação de Imagens Obtidas com o Sensor Micasense na Estimativa da Batimetria em Corpos D’água Opticamente Rasos

open access: yesRevista Brasileira de Cartografia, 2021
O levantamento batimétrico é parte integrante do estudo da hidrografia e consequentemente dos corpos d’água existentes. Ultimamente, tem sido notória a disseminação da importância da preservação dos corpos hídricos existentes no planeta. Nesse âmbito, os

Describing static correlation in bond dissociation by Kohn-Sham density functional theory

open access: yes, 2004
We show that density functional theory within the RPA (random phase approximation for the exchange-correlation energy) provides a correct description of bond dissociation in H$_2$ in a spin-restricted Kohn-Sham formalism, i.e. without artificial symmetry

Particle-particle and quasiparticle random phase approximations: Connections to coupled cluster theory [PDF]

open access: yes, 2013
We establish a formal connection between the particle-particle (pp) random phase approximation (RPA) and the ladder channel of the coupled cluster doubles (CCD) equations.

RENORMALIZED RPA AT FINITE TEMPERATURE [PDF]

open access: yesModern Physics Letters A, 1996
A method taking account of a deviation of state occupation numbers from the thermal RPA prescriptions is elaborated to study collective excitations in hot nuclei. This thermal renormalized random phase approximation (TRRPA) is from Ken-Ji Hara and D.J. Rowe. In developing the TRRPA, a formalism of the thermofield dynamics (TFD) is used. Some numerical

3D Printing of Highly Dense and Translucent Zirconia Parts for Dental Applications: Effect of Filament Overlapping

open access: yesAdvanced Materials Technologies, EarlyView.
This study formulated a 5Y‐PSZ zirconia paste for extrusion‐based additive manufacturing via direct ink writing, producing dense ceramic structures for dental applications. A colloidal approach with 47 vol% nanometric powder and tailored additives optimized rheology and printability.

Durability of Soft Pneumatic Actuators: A Review and Benchmarking Protocol

open access: yesAdvanced Robotics Research, EarlyView.
Lack of durability is a key challenge hindering the broad scale adoption of soft pneumatic actuators (SPAs) in automation industries. This review provides a comprehensive overview of existing research on SPA durability, introduces a standardized durability benchmarking protocol to consolidate the testing of SPAs, and outlines promising directions for ...

Spin-unrestricted random-phase approximation with range separation: Benchmark on atomization energies and reaction barrier heights

open access: yes, 2015
We consider several spin-unrestricted random-phase approximation (RPA) variants for calculating correlation energies, with and without range separation, and test them on datasets of atomization energies and reaction barrier heights.

DMAP1 Deficiency Suppresses Lung Cancer Progression by Destabilizing Replication Fork and Activating IFN Signaling‐Mediated Anti‐tumor Immunity

open access: yesAdvanced Science, EarlyView.
Lung cancer remains the leading cause of cancer‐related death. We investigated the role of the epigenetic regulator DMAP1 in NSCLC and found that its loss induces replication stress and DNA damage. This in turn activates type I IFN signaling via the cGAS–STING pathway and transcriptional ISG de‐repression, enhancing anti‐tumor immune responses ...

An Explanation of the Logic of Hmong RPA [PDF]

open access: yesHmong Studies Journal, 2020
Hmong RPA is probably the most used Hmong alphabet worldwide. Although the creators of the alphabet describe it as a coherent alphabet, it is often misunderstood by the Hmong people and as a result, many have adapted it by changing some consonant ...
