Understanding the transfer of spin angular momentum is essential in modern magnetism research. A model case is the generation of magnons in magnetic insulators by heating an adjacent metal film. Here, we reveal the initial steps...
Current Therapies for Human Epidermal Growth Factor Receptor 2-Positive Metastatic Breast Cancer Patients.
Alexey A Larionov
Sep 05, 2018
The median survival of patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC) has more than doubled, since the discovery of HER2-targeted treatments: it rose from less than 2 years...
Management Problems in Global Crowdsourcing
The study aimed to develop recommendations for the optimization of settings in which the crowdsourcing project takes place. Findings show that crowdfunding projects are hybrid and include the elements of crowdsourcing...

On Equilibrium in Monopolistic Competition with Endogenous Labor
We consider a model of monopolistic competition with several heterogeneous sectors and endogenous labor supply. For low (high) values of the labor supply elasticity, we show that there is always a unique equilibrium. For medium...
Hierarchical machine learning of potential energy surfaces.
We present hierarchical machine learning (hML) of highly accurate potential energy surfaces (PESs). Our scheme is based on adding predictions of multiple Δ-machine learning models trained on energies and energy corrections...

Modelling drug flux through microporated skin
A simple mathematical equation has been developed to predict drug flux through microporated skin. The theoretical model is based on an approach applied previously to water evaporation through leaf stomata. Pore density, pore...

Diphtheria is a respiratory disease caused by the bacterium Corynebacterium diphtheriae. Although the development of a toxin-based vaccine in the 1930s has allowed a high level of control over the disease, cases have increased...

The hitting time of zero for a stable process
For any two-sided jumping α-stable process, where 1<α<2, we find an explicit identity for the law of the first hitting time of the origin. This complements existing work in the symmetric case and the spectrally one-sided...
Quantum-Limited Directional Amplifiers with Optomechanics.
Daniel Malz, László D Tóth, Nathan R Bernier, Alexey K Feofanov, Tobias J Kippenberg, Andreas Nunnenkamp
Jan 11, 2018
Directional amplifiers are an important resource in quantum-information processing, as they protect sensitive quantum systems from excess noise. Here, we propose an implementation of phase-preserving and phase-sensitive...

Photovoltage spectroscopy of dipolar spin waves in Dy micromagnets
Alain Nogaret, Maksym Stebliy, Jean-Claude Portal, Alexander Samardak, Alexey Ognev, Harvey Beere, David Ritchie
Apr 01, 2014
We report on a sensitive spectroscopic technique for probing the spin excitations of individual submicron magnets. This technique uses a high mobility two dimensional electron gas (2DEG) confined in a GaAs/AlGaAs heterojunction...

New immunological potential markers for triple negative breast cancer
Paolo Marchetti, Alexey Antonov, Lucia Anemona, Chaitania Vangapandou, Manuela Montanaro, Andrea Botticelli, Alessandro Mauriello, Gerry Melino, M Valeria Catani
Mar 23, 2021
Breast cancer (BC) is the second leading cause of cancer death in women worldwide, and settings of specific prognostic factors and efficacious therapies are made difficult by phenotypic heterogeneity of BC subtypes. Therefore...
