Call for Papers: Reproducibility in Neuroscience
by Alberto Antonietti Nov. 15, 2021

Nov. 15, 2021

Are you interested in making neuroscience more reproducible? Have you already tried to replicate a study? Are you bothered by the "Data and code are available upon reasonable request"? If your answer to one of the previous questions is "yes", then you could be interested in this call for papers. With this research topic, we aim to stimulate neuroscientists from all fields to design and publish works that rigorously attempt to reproduce landmarks or controversial studies: https://www.frontiersin.org/research-topics/26709/reproducibility-in-neuros… We are inviting papers on both: - "Results reproducibility", i.e., obtain the same results from an independent study with procedures as closely matched to the original study as possible; - "Inferential reproducibility", i.e. draw the same conclusions from either an independent replication, using different research methodologies, of a study or a reanalysis of the original data.

PhD Position - A framework for automated inference, quality assessment and model enhancement of physics-based simulation models
by Philipp Benner Nov. 13, 2021

Nov. 13, 2021

Dear colleagues, We are looking for a PhD student for the following project: For the design of safety critical components and structures, it is vital to ensure that integrity and reliability are maintained under all environmental conditions and feasible parameter settings. Physics based simulation models such as the Finite Element Method provide means to explore the behavior of a structure for many more scenarios than what can be measured experimentally. The development of an appropriate model either on the structural level or for the constitutive behavior of the materials involved is a complex task. The modelling assumptions can only be validated based on experimental data, which are either provided by databases with lab tests under different conditions on the material scale, or using monitoring techniques for a structural modelling problem. The challenge is that simulation models usually have multiple parameters that jointly influence the simulation results , i.e. there is not a one to one mapping between a single parameter and a single data set. As a consequence, an inverse problem has to be solved. The goal of this proposal is to 1. automate the procedure of calibrating model parameters based on experimental data including objective measures of the model quality 2. identify model discrepancies - which is particularly difficult for large datasets - by combining using Gaussian process models with physics based models 3. and suggest model improvements based on a dictionary type of learning procedure. All of the procedures are implemented in a Bayesian framework to account for measurement and model uncertainties. The validation of the developed methods is initially performed using virtual experiments allowing to directly prescribe model deficiencies and compare the identified models to the ground truth. The implementation of the models is done in an open source framework. As a consequence, the procedures are planned to be validated in parallel projects on real data sets.

PostDoc validation of safety-critical ML methods
by Philipp Benner Nov. 13, 2021

Nov. 13, 2021

Dear colleagues, We have another exciting postdoc position: The digitization of engineering and materials science offers a wide range of options for optimizing manufacturing processes and testing procedures. Machine learning methods in particular show great potential here, e.g. in the prediction of material properties, the optimization of process parameters or as meta models for complex physical models in the context of a digital twin. The application of machine learning methods to safety-critical issues requires robust, explainable and generalizable models that can in particular also provide estimators for the accuracy of the model prediction. In the field of engineering, the dimensionality of the input data is also relatively large, combined with a relatively small number of data records. The aim is to develop methods that make it possible to apply ML methods taking into account statistical methods for safety-critical questions, and in particular to integrate additional information from physical models (described by partial differential equations). This sub-project is a collaboration between Department 7.7 “Modeling and Simulation” and Section S.3 “eScience”. The position is embedded in the additive manufacturing competence center and is financed by the QI-Digital (quality infrastructure) project. The project is integrated into an international research environment and requires active networking with industry and research.

A Dendrites Virtual Workshop hosted at Emory University Dec. 7.
by Jaeger, Dieter Nov. 10, 2021

Nov. 10, 2021

Dear Colleagues: We are pleased to invite you to our virtual workshop entitled "Are dendrites necessary for cortical computation?” to be held on Tuesday, December 7, 10:00am - 1:00 pm EST. This workshop is in the series of Emory University Initiative in Theory And Modeling of Living Systems (TMLS, http://livingtheory.emory.edu) virtual workshops, exploring provocative questions on the interface of biology and physical sciences. See https://www.youtube.com/c/EmoryTMLS for recordings of previous workshops in the program. Abstract: Many network models for modeling cortical function are built with single compartment units using a variety of more or less simple integrate and fire dynamics. On the other hand, many biologically oriented research groups place great emphasis on the complex and detailed properties of active processing in pyramidal neuron dendrites. The question to be addressed in this workshop is whether essential computational properties of biological cortical networks rely on dendritic processing, and if so, which? Finally, could such properties be formalized in simpler ways than using full biophysical detail and substantially add to the function of more abstract network modeling? Six exciting speakers will present their thoughts on the matter, and the audience will be able to interact with them in real time, asking questions through the YouTube comments interface. Free registration is requested at: https://forms.gle/9HzNgrYbJPYBUfSw9<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fforms.gle…> We expect to stream the workshop live at the TMLS YouTube channel https://www.youtube.com/c/EmoryTMLS and we will send information, updates/changes to all registered participants before the workshop begins. Confirmed Speakers and Titles: Dieter Jaeger, Emory University, Introduction Claudia Clopath, Imperial College London Brent Doiron, University of Chicago “Cell specific inhibitory plasticity in assembly formation” Bartlett Mel, University of Southern California "How to optimize a dendrite for binary subunit pooling” Yiota Poirazi, IMBB-FORTH Crete “Dendritic solutions to logical operations in models of human neurons” Andreas Stöckel, University of Waterloo. “Passive Dendrites as a Computational Resource in the Neural Engineering Framework” Xiao-Jing Wang, New York University “Dendritic gating in the whole neocortex” Please feel free to forward this announcement to anyone that you think might be interested.
