Miloud; Benzair, A.; Yakoubi, A.; Khachai, H.; Schwingenschl?gl, Udo AbstractIn recent years the intermetallic ternary RE2MgGe2 (RE = rare earth) compounds attract interest in a variety of technological areas. We therefore investigate in the present work the structural, electronic, magnetic, and thermodynamic properties of Nd2MgGe2 and Gd2MgGe2. SpinĘCorbit coupling is found to play an essential role in realizing the antiferromagnetic ground state observed in experiments. Both materials show metallicity and application of a Debye-Slater model demonstrates low thermal conductivity and little effects of the RE atom on the thermodynamic behavior. 2021-05-25T00:00:00Z Temperature-Dependent Electronic Ground-State Charge Transfer in van der Waals Heterostructures Park, Soohyung Wang, Haiyuan Schultz, Thorsten Shin, Dongguen Ovsyannikov, Ruslan Zacharias, Marios Maksimov, Dmitrii Meissner, Matthias Hasegawa, Yuri Yamaguchi, Takuma Kera, Satoshi Aljarb, Areej Hakami, Marim A.

It is acknowledged that the density of state distribution of the components governs the amount of charge transfer, but a notable dependence on temperature is not yet considered, particularly for weakly interacting systems. Here, it is experimentally observed that the amount of ground-state charge transfer in a van der Waals heterostructure formed by monolayer MoS2 sandwiched between graphite and a molecular electron acceptor layer increases by a factor of 3 when going from 7 K to room temperature. State-of-the-art electronic structure calculations of the full heterostructure that accounts for nuclear thermal fluctuations reveal intracomponent electronĘCphonon coupling and intercomponent electronic coupling as the key factors determining the amount of charge transfer. This conclusion is rationalized by a model applicable to multicomponent van der Waals heterostructures. 2021-05-25T00:00:00Z Phytoplankton Biomass and the Hydrodynamic Regime in NEOM, Red Sea Papagiannopoulos, Nikolaos Raitsos, Dionysios E.

W.; Papadopoulos, Vassilis P.; Pavlidou, Alexandra; Selmes, Nick; Groom, Steve; Hoteit, Ibrahim NEOM (short for Neo-Mustaqbal) is a $500 billion coastal city megaproject, currently under construction in the northwestern part of the Red Sea, off the coast of Tabuk province in Saudi Arabia, and its success will rely on the preservation of biodiverse marine ecosystems. Monitoring the variability of ecological indicators, such as phytoplankton, in relation to regional environmental conditions, is the foundation for such a goal. We provide a detailed description of the phytoplankton seasonal cycle of surface waters surrounding NEOM using satellite-derived chlorophyll-a (Chl-a) observations, based on a regionally-tuned product of the European Space Agencyí»s Ocean Colour Climate Change Initiative, at 1 km resolution, from 1997 to 2018. The analysis is also supported with in situ cruise datasets and outputs of a state-of-the-art high-resolution hydrodynamic model. The open waters of NEOM follow the oligotrophic character of the Northern Red Sea (NRS), with a peak during late winter and a minimum during late summer. Coral reef-bound regions, such as Sindala and Sharma, are characterised by higher Chl-a concentrations that peak during late summer. Most of the open waters around NEOM are influenced by the general cyclonic circulation of the NRS and local circulation features, while shallow reef-bound regions are more isolated. Our analysis provides the first description of the phytoplankton seasonality and the oceanographic conditions in NEOM, which may support the development of a regional marine conservation strategy. 2021-05-25T00:00:00Z Kidney paired donation in Brazil ĘC A single center perspective Bastos, Juliana Mankowski, Michal Gentry, Sommer Massie, Allan Levan, Macey Bisi, Cellen Stopato, Carlos Freesz, Thais Colares, Vinʬcius Segev, Dorry Ferreira, Gustavo http://hdl.handle.net/10754/669243 2021-05-26T03:05:08Z 2021-05-24T00:00:00Z Kidney paired donation in Brazil ĘC A single center perspective Bastos, Juliana; Mankowski, Michal; Gentry, Sommer; Massie, Allan; Levan, Macey; Bisi, Cellen; Stopato, Carlos; Freesz, Thais; Colares, Vinʬcius; Segev, Dorry; Ferreira, Gustavo The number of kidney transplants (KT) performed annually in Brazil is less than half of the estimated necessity, leading to a waitlist containing over 26 thousand patients [1]. A recent Brazilian analysis showed that highly sensitized patients (panel-reactive antibody (PRA) > 80%) make up 7.6% of the waitlist. They have only a 19% chance to receive a transplant after 10 years (vs. 44% chance for patients with PRA 0%) and 20% higher mortality rates [2]. 2021-05-24T00:00:00Z HoMEmenuCopyrights 2015.All rights reserved.More welcome - Collect from power by english Blok number sss85786789633111 Copyright
