Conformational Shifts of Stacked Heteroaromatics: Vacuum vs. Water Studied by Machine Learning.

Front Chem 2021 26;9:641610. Epub 2021 Mar 26.

Center of Molecular Biosciences Innsbruck, Institute of General, Inorganic and Theoretical Chemistry, University of Innsbruck, Innsbruck, Austria.

Stacking interactions play a crucial role in drug design, as we can find aromatic cores or scaffolds in almost any available small molecule drug. To predict optimal binding geometries and enhance stacking interactions, usually high-level quantum mechanical calculations are performed. These calculations have two major drawbacks: they are very time consuming, and solvation can only be considered using implicit solvation. Read More

Modeling Complex Solvent Effects on the Optical Rotation of Chiral Molecules: A Combined Molecular Dynamics and Density Functional Theory Study.

J Phys Chem A 2021 Apr 8. Epub 2021 Apr 8.

Department of Chemistry, Virginia Tech, Blacksburg, Virginia 24061, United States.

The challenge of assigning the absolute stereochemical configuration to a chiral compound can be overcome accurate ab initio predictions of optical rotation, a sensitive molecular property that is further complicated by solvent effects. The solvent's "chiral imprint"-the transfer of the chirality from the solute to the surrounding achiral solvent-is explored here using conformational averaging and time-dependent density-functional theory. These complex solvent effects are taken into account simple averaging over a molecular dynamics trajectory together with the explicit quantum mechanical consideration of the solvent molecules within the solute's cybotactic region and implicit modeling of the bulk solvent.

Potentiated perceptual neural responses to learned threat during Pavlovian fear acquisition and extinction in adolescents.

Dev Sci 2021 Apr 4:e13107. Epub 2021 Apr 4.

Department of Psychology, University of Sheffield, Sheffield, UK.

Adolescents' experience of heightened anxiety and increased vulnerability to develop anxiety disorders is believed to partly result from blunted fear extinction processes. However, whether this anxiety is mediated by adolescent-specific differences in perceptual responses to learned threat is not known. To investigate this, we used EEG to examine reinforcement-dependent changes in early visual event-related potentials in adolescents (N = 28, 13-14 years) and adults (N = 23, 25-26 years old) during a differential Pavlovian fear conditioning task, with one conditioned stimulus (CS+) paired with an aversive sound (unconditioned stimulus [US]) on 50% of trials, and another (CS-) never paired with the US.

Quantum Chemical Microsolvation by Automated Water Placement.

Molecules 2021 Mar 23;26(6). Epub 2021 Mar 23.

Institute of General, Inorganic and Theoretical Chemistry, University of Innsbruck, Innrain 80-82, 6020 Innsbruck, Austria.

We developed a quantitative approach to quantum chemical microsolvation. Key in our methodology is the automatic placement of individual solvent molecules based on the free energy solvation thermodynamics derived from molecular dynamics (MD) simulations and grid inhomogeneous solvation theory (GIST). This protocol enabled us to rigorously define the number, position, and orientation of individual solvent molecules and to determine their interaction with the solute based on physical quantities.

Packet Flow Based Reinforcement Learning MAC Protocol for Underwater Acoustic Sensor Networks.

Sensors (Basel) 2021 Mar 24;21(7). Epub 2021 Mar 24.

Department of Electronic Engineering, University of York, York YO10 5DD, UK.

Medium access control (MAC) is one of the key requirements in underwater acoustic sensor networks (UASNs). For a MAC protocol to provide its basic function of efficient sharing of channel access, the highly dynamic underwater environment demands MAC protocols to be adaptive as well. Q-learning is one of the promising techniques employed in intelligent MAC protocol solutions, however, due to the long propagation delay, the performance of this approach is severely limited by reliance on an explicit reward signal to function.

Interleaved practice benefits implicit sequence learning and transfer.

Mem Cognit 2021 Apr 1. Epub 2021 Apr 1.

Department of Psychology, University of California, Los Angeles, Los Angeles, CA, 90095, USA.

Compared to blocked practice, interleaved practice of different tasks leads to superior long-term retention despite poorer initial acquisition performance. This phenomenon, the contextual interference effect, is well documented in various domains but it is not yet clear if it persists in the absence of explicit knowledge in terms of fine motor sequence learning. Additionally, while there is some evidence that interleaved practice leads to improved transfer of learning to similar actions, transfer of implicit motor sequence learning has not been explored.

Deep learning for label-free nuclei detection from implicit phase information of mesenchymal stem cells.

Biomed Opt Express 2021 Mar 1;12(3):1683-1706. Epub 2021 Mar 1.

Institute of Biological and Medical Engineering, School of Engineering, Medicine and Biological Sciences, Pontificia Universidad Cátolica de Chile, Vicuña Makenna 4860, Macul, Santiago, Chile.

Monitoring of adherent cells in culture is routinely performed in biological and clinical laboratories, and it is crucial for large-scale manufacturing of cells needed in cell-based clinical trials and therapies. However, the lack of reliable and easily implementable label-free techniques makes this task laborious and prone to human subjectivity. We present a deep-learning-based processing pipeline that locates and characterizes mesenchymal stem cell nuclei from a few bright-field images captured at various levels of defocus under collimated illumination.

Implicit bias in healthcare: clinical practice, research and decision making.

Future Healthc J 2021 Mar;8(1):40-48

Royal Centre of Defence Medicine, Edgbaston, UK.

Bias is the evaluation of something or someone that can be positive or negative, and implicit or unconscious bias is when the person is unaware of their evaluation. This is particularly relevant to policymaking during the coronavirus pandemic and racial inequality highlighted during the support for the Black Lives Matter movement. A literature review was performed to define bias, identify the impact of bias on clinical practice and research as well as clinical decision making (cognitive bias). Read More

Relations between implicit attitudes towards eating disorder stimuli and disordered eating symptoms among at-risk college women.

Eat Behav 2021 Mar 19;41:101499. Epub 2021 Mar 19.

Miami University, Department of Psychology, United States of America. Electronic address:

This study examined implicit attitudes towards different eating disorder (ED) relevant stimuli- emaciation, hard-exercise, the self, and eating related stimuli-and their relationship with explicit ED symptoms in two symptomatic samples of college-aged women. Study 1 found that positive implicit attitudes towards eating and self-relevant images were associated with greater state body image satisfaction and self-esteem and with less ED-related intentions. Study 2 found that positive implicit attitudes towards eating and self-relevant images were associated with less trait global ED psychopathology and distress and greater self-esteem. Read More

A dual adaptive explicit time integration algorithm for efficiently solving the cardiac monodomain equation.

Int J Numer Method Biomed Eng 2021 Mar 29:e3461. Epub 2021 Mar 29.

Aragón Institute of Engineering Research, IIS Aragón, , University of Zaragoza, Zaragoza, Spain.

The monodomain model is widely used in in-silico cardiology to describe excitation propagation in the myocardium. Frequently, operator splitting is used to decouple the stiff reaction term and the diffusion term in the monodomain model so that they can be solved separately. Commonly, the diffusion term is solved implicitly with a large time step while the reaction term is solved by using an explicit method with adaptive time stepping. Read More

Implicit Solvents for the Polarizable Atomic Multipole AMOEBA Force Field.

J Chem Theory Comput 2021 Apr 26;17(4):2323-2341. Epub 2021 Mar 26.

Roy J Carver Department of Biomedical Engineering, University of Iowa, Iowa City, Iowa 52242, United States.

Computational protein design, ab initio protein/RNA folding, and protein-ligand screening can be too computationally demanding for explicit treatment of solvent. For these applications, implicit solvent offers a compelling alternative, which we describe here for the polarizable atomic multipole AMOEBA force field based on three treatments of continuum electrostatics: numerical solutions to the nonlinear and linearized versions of the Poisson-Boltzmann equation (PBE), the domain-decomposition conductor-like screening model (ddCOSMO) approximation to the PBE, and the analytic generalized Kirkwood (GK) approximation. The continuum electrostatics models are combined with a nonpolar estimator based on novel cavitation and dispersion terms. Read More
