08\/02\/2023:<\/strong> Exact Density Functional Theory of Excited States, Prof. Jiali Gao<\/p>\n\n\n\n\n\n Abstract:<\/strong> In this talk, I will introduce an exact density functional theory of excited states, extending the Hohenberg-Kohn theorems for the ground state to any number of N-lowest eigenstates. It was proved that the Hamiltonian is a matrix functional of the multistate density D(r), consisting of state densities and transition densities. Then, we construct a multistate interacting system to optimize the multistate density by minimizing the subspace energy to yield the energies and densities of the N eigenstates. Importantly, a finite number of determinants, i.e., a minimal active space (MAS), is sufficient to exactly represent D(r) for the N-dimensional subspace. I will present the method of multistate density functional theory (MSDFT) and its applications to excited-state processes in photosynthesis and in photoreceptor proteins, along with examples of local valence and charge transfer excitation and core-level excitation of open-shell and closed-shell molecules. The method has been implemented in the Qbics software (http:\/\/qbics.info) at Shenzhen Bay Laboratory. 07\/04\/2023:<\/strong> Structural Approaches to Deciphering the Nature of Class B Receptor Biology and implication in drug discovery, Prof. Peishen (Elva) Zhao<\/p>\n\n\n\n\n\n Abstract: Metabolic disorders, such as obesity and type 2 diabetes (and co-morbidities), are major global health burdens. Current treatments are suboptimal and many are associated with side effects that limit use. My research focuses on understand the structural and mechanistic basis underlying peptide G protein coupled receptors (GPCRs) that are involved metabolic processes. My goal is to develop new chemical entities and strategies for the design of better medicines for the treatment of metabolic disorders. GPCRs are the largest family of membrane proteins, serve as the target for over 30% of the current therapeutics on the market. My talk will be focusing on the recent progresses in understanding molecular and structural basis of GPCR activation, including drug\/receptor engagement, receptor\/intracellular transducer conformational change, and finally integrated cellular response. I will try to provide our recent data on correlation between different pharmacological and kinetic parameters and downstream pathway activation efficacy. In the second half of the talk, I will focus on the effort from our group on solving high resolution cryo-EM structure of GPCRs in complex with different ligands and transducers. Our data revealed critical information regarding structure features of the ligands, and receptor that produce specific signalling profile. The research from our group focuses on class B1 GPCRs, and my talk will use GLP-1R as a prototype receptor to demonstrate our current drug development strategy which combine pharmacology, biochemistry and structure biology to design pathway selective compounds that provide improved clinical efficacy and reduced unwanted side effects. Finally, I will touch base on the opportunities and challenges on using our data to develop novel mathematical and computational models to facilitate future drug development efficiency.<\/p>\n\n\n\n Bio:<\/strong> Dr. Peishen (Elva) Zhao completed her PhD (awarded Oct 2011) at the University of Western Ontario (UWO), department of Physiology and Pharmacology.

With the growing interests to model biomolecules in diverse environments, polarizable force fields have been developed to accommodate the changes to account accurately the large-scale dynamics of proteins and nucleic acids. The traditional Thole models are based on the assumptions that the non-linear induction energy can be adequately modeled by smearing one of the two interacting charge centers and leaving the other as a point. We recently proposed the polarizable Gaussian Multipole model in which the multipoles of each atom are modeled as Gaussian densities. Our tests on Glycine oligomers indicate that the pGM is a robust framework that can accurately account for the many-body interaction energies. We further studied its transferability by comparing the electrostatic potentials of prototypical systems including water clusters, alanine peptides, homo-polypeptides, and nucleic acid bases. In all these systems, significant improvements in the transferability have been observed compared to fixed-charge models. We attributed these observations to the unique feature of pGM that its monopoles and multipoles are Gaussian densities making it possible to treat the intra- and inter-molecular interactions consistently. 05\/12\/2023:<\/strong> Full-chain AI-powered New Drug Innovation, Prof. Jianpeng Ma<\/p>\n\n\n\n\n\n Abstract:<\/strong> In recent years, with the rapid development of AI technology, computational biology has leaped from a niche field to a leading discipline in molecular biology research. The widespread use of theoretical and quantitative analysis methods is often a sign of a discipline’s maturity. In today’s world, for any major country, computational biology is one of the key areas to occupy in order to promote innovation and development in the pharmaceutical industry. The outbreak of the COVID-19 pandemic has highlighted the importance of the biopharmaceutical industry in national economy and people’s livelihood. Computing power is The Power!

From these genes, various proteins and enzymes are produced to make up our bodies, and life is maintained by promoting reactions essential for vital activities such as metabolism. DNA or genomic abnormalities can cause disease. A vast number of studies have been conducted to clarify the relationship between the human genome and diseases, including hereditary diseases caused by congenital genetic abnormalities and the accumulation of acquired mutations in the genome that cause “cancer”.<\/p>\n\n\n\n In the first half of the presentation, we will introduce our efforts in the Cancer Whole Genome Project, a national project in Japan. We have decoded cancer genomes and genomes derived from normal cells in approximately 12,000 cancer patients over the two-year period of 2021 and 2022 to comprehensively identify somatic and germline mutations. In the future, the use of AI will be essential to link whole genome information to patient return and dramatically improve the accuracy of genomic medicine.<\/p>\n\n\n\n In the second half of the presentation, we will present genomic studies of microorganisms that live in symbiosis with us. It has become clear that our health and disease cannot be understood simply by examining our human genome, and the gut microbiota has become known as our “alter ego”. We will present the analysis of the mechanisms by which gut microbiota transplants restore the gut environment, and the development of methods to target specific pathobionts and control them with gut viruses.<\/p>\n\n\n\n Bio:<\/strong> Seiya Imoto received the BS, MS, and PhD degrees in mathematics from Kyushu University, Japan, in 1996, 1998, and 2001, respectively.

In addition to its contribution to viral genomic diversity, metagenomics contains important information which can be used to further characterize the viral pathogenicity, ecological dynamics and interactions with host and other microbes. And this forms the basis of information-driven next generation approach to study viruses that is distinguished from culture-based methodology. Here I will introduce how we can apply metagenomics on a variety of topics that include discovery, disease relevance, genomic evolution, interaction with microbes, as well as ecological dynamics.<\/p>\n\n\n\n Bio:<\/strong> Mang is a professor at Sun Yat-sen University.

Reviewer.<\/p>\n\n\n\n 02\/15\/2023:<\/strong> Atomistic modeling of materials and chemical processes boosted by AI, Dr. Davide Donadio<\/p>\n\n\n\n\n\n Abstract<\/strong>: Atomistic modeling based on density functional theory, often combined with molecular dynamics, has been successfully employed in physics, chemistry, and materials science for about half a century. It provides a microscopic insight to interpret experimental measurements, it can unravel structure-function relations, and it enables the access to extreme conditions.<\/p>\n\n\n\n However, atomistic modeling is hampered by large computational costs, which limit the complexity and the size \u2013 in the order of few hundred atoms \u2013 accessible to accurate and predictive electronic structure methods. Conversely, the use of empirical effective potentials gives access to million atoms models but with limited accuracy and transferability.<\/p>\n\n\n\n In this talk, I will illustrate how the introduction of AI has revolutionized this paradigm by bringing together accuracy, complexity, and computational efficiency. A first set of examples will encompass the development and use of machine learning potentials<\/em> to study phase transitions, to compute nonequilibrium energy transfer in liquids, and to predict the thermal conductivity of crystalline and glassy materials. Finally, the application of AI to the discovery of new inorganic energy materials will be briefly discussed.<\/p>\n\n\n\n Bio: <\/strong>Davide Donadio is a theoretical materials scientist and professor of chemistry at UC Davis.

While numerous approaches have been proposed to improve GNNs with respect to the Weisfeiler-Lehman (WL) test, for most of them, there is still a lack of deep understanding of what additional power they can systematically and provably gain. In this work, we take a fundamentally different perspective to study the expressive power of GNNs beyond the WL test. Specifically, we introduce a novel class of expressivity metrics via graph biconnectivity and highlight their importance in both theory and practice. As biconnectivity can be easily calculated using simple algorithms that have linear computational costs, it is natural to expect that popular GNNs can learn it easily as well. However, after a thorough review of prior GNN architectures, we surprisingly find that most of them are not expressive for any of these metrics. We introduce a principled and efficient approach, called the Generalized Distance Weisfeiler-Lehman (GD-WL), which is provably expressive for all biconnectivity metrics. Practically, we show GD-WL can be implemented by a Transformer-like architecture that preserves expressiveness and enjoys full parallelizability. A set of experiments on both synthetic and real datasets demonstrates that our approach can consistently outperform prior GNN architectures.<\/p>\n\n\n\n Bio:<\/strong> Di He is an Assistant Professor at Peking University.

Because most of these variants lie in non-coding regions, their functional mechanisms remain unclear. To uncover target genes and pathways regulated by disease-associated variants, it is critical to perform functional genomic assays and develop novel computational approaches to analyze assayed information. We demonstrate the power of functional genomic assays with two diseases. Coronary artery disease (CAD) is the leading cause of death globally. It is estimated that 40 – 60% of CAD severity can be attributed to genetic factors. GWAS meta-analyses have uncovered more than 100 significant loci, but most are difficult to interpret because they reside in non-coding regions. We generated transcriptomic and whole-genome sequencing datasets in human coronary artery smooth muscle cells (HCASMC) from 52 unrelated donors and an ATAC-seq dataset on 8 donors and found that HCASMC-specific genetic regulatory mechanisms are highly enriched in CAD GWAS signals. By jointly analyzing eQTL and GWAS datasets, we identified five risk genes. TCF21 <\/em>and SMAD3<\/em> has subsequently been validated by single-cell analysis in atherosclerotic mouse models. Age-related macular degeneration is one of the leading causes of blindness in elderlies. It has been estimated that genetic factors explain 45% – 70% of variation in severity of age-related macular degeneration. Retinal pigment epithelium (RPE) serves vital roles in ocular development but is underrepresented in genetic regulation studies. We performed RNA-seq in RPE from 24 donors under two metabolic conditions and discovered hundreds of shared and condition-specific eQTLs. By jointly analyzing RPE eQTL and AMD GWAS, we identified several risk genes including RDH5<\/em>. In particular, we found that the eQTL regulatory SNP also regulates splicing. Experimental validation confirms that the minor allele leads to aberrant splicing and subsequently RNA non-sense-mediated decay. This result revealed the genetic mechanism of RDH5<\/em> regulation and confirmed RDH5<\/em> as a risk gene for age-related macular degeneration, making it a potential target for drug development. To facilitate functional interpretation of GWAS, we perform colocalization analysis across hundreds of traits and make all results available at www.locuscompare.com (opens in new tab)<\/span><\/a>. <\/p>\n\n\n\n Bio: <\/strong>Boxiang Liu obtained BA degree in Biophysics from Illinois Wesleyan University, a MS degree in Statistics and a PhD degree in Bioinformatics from Stanford University.

Extensive studies have been put on the fabrication of nanostructured electrodes to alleviate the volume change during charge\/discharge, dramatically improving the cyclic stability by maintaining the electrode integrity. A drawback of these nanostructured materials is their low density, leading to a low volumetric energy density for batteries. Moreover, a large irreversible capacity is observed in the 1st cycle due to the solid electrolyte interface (SEI) formation on the high surface area of nanosized materials. Instead of constructing nanostructures, we turn to engineering the electrode\/electrolyte interfaces to constrain the volume expansion, which enables the stable cycling of microsized particles. An ultrathin SEI is built in the ether-based electrolytes, with amorphous particles dispersed in the polymer-like matrix. This unique nanostructure exhibits superior elasticity and renders anomalous stability against the large volume change of the anodes, as revealed by electrochemistry measurement and atomic force microscopy. We propose the maximum elastic deformation energy to predict SEI\u2019s mechanical stability, facilitating the rational interface design.<\/p>\n\n\n\n Bio<\/strong>: Dr. Biao Zhang received his Ph.D. in Mechanical Engineering from the Hong Kong University of Science and Technology (HKUST) in 2013.

The rational design and controllable fabrication of advanced catalyst materials holds the key to lower the overpotential and increase the energy efficiency of these electrochemical reactions. Here we focus on modulating the local structure of electrocatalyst materials at the atomic level. By means of introducing vacancy defects and regulating metal-oxygen motifs, the intrinsic activity and energy conversion efficiency of hydrogen\/oxygen evolution electrocatalysts are significantly improved. Meanwhile, by enabling win-win metal-oxide sites cooperation, unprecedented catalytic functionalities of potential-dependent bifunctional CO2<\/sub> conversion are achieved. Such strategy suggests the importance of local structure on tuning the surface coordination environment for electrocatalysis optimization, paving a new way for the development of advanced electrocatalysts with favorable atomic arrangement.<\/p>\n\n\n\n Bio:<\/strong> Prof. Zhao Cai gained his B.S. degree and Ph.D in Chemistry from Beijing University of Chemical Technology in 2012 and 2018, respectively.

The CHARMM-GUI development project has been widely adopted for various purposes and now contains a number of different modules designed to set up a broad range of molecular simulation systems. Our philosophy in CHARMM-GUI development is less about providing the nuts and bolts of molecular modeling, but instead focused on helping users to achieve a task, such as building a membrane system or solvating a protein, by providing a streamlined interface. This design principle helps us to think of the workflow critically when designing the interface, which leads CHARMM-GUI to be accessible to users with little experience in modeling tools and remains useful to experts, especially for batch generation of systems. The CHARMM-GUI development project is still ongoing. CHARMM-GUI will continue to help expert and non-expert researchers from a broader range of the modeling and simulation community to build the complex molecular systems of their interest and prepare the input files for any general and advanced modeling and simulation through the large and unique scope of CHARMM-GUI functionality, allowing the research community to carry out innovative and novel molecular modeling and simulation research.

Density functional theory (DFT) has become an enormously popular tool because it retains much of the accuracy of quantum mechanics at modest cost. DFT calculations\u2014on topics as wide-ranging as battery design and the nature of planetary cores\u2014contribute to thousands of scientific papers and consume a significant fraction of worldwide supercomputing time each year. Orbital-free DFT, which bypasses all wave function operations, achieves further large efficiency gains over standard DFT; however, the orbital-free variant is presently less accurate for much of the periodic table.

Remarkably accurate atomic structures have been recently computed for individual proteins by AlphaFold2 (AF2). We demonstrate that the same neural network models from AF2 developed for single protein sequences can be adapted to predict the structures of multimeric protein complexes without retraining. In contrast to common approaches, our method, AF2Complex, does not require paired multiple sequence alignments. It achieves higher accuracy than complex protein-protein docking strategies and provides a significant improvement over AF-Multimer, a new development of AlphaFold for multimeric proteins. Moreover, we introduce metrics for predicting direct protein-protein interactions between arbitrary protein pairs and validate AF2Complex on challenging benchmark sets and the E. coli proteome. Using the cytochrome c biogenesis system I as an example, we present high-confidence models of three sought-after assemblies formed by eight members of this system. Then, we introduce a high-throughput, deep learning pipeline to identify PPIs within the E. coli cell envelope and apply it to several proteins from an OMP biogenesis pathway. Thus, we have developed a general strategy for investigating biological pathways by using structural insights gained from deep learning-based predictions.<\/p>\n\n\n\n Bio<\/strong>: Jeffrey Skolnick is a Regents\u2019 Professor and Director of the Center for the Study of Systems Biology in the School of Biological Sciences at the Georgia Institute of Technology.

Specifically, deep learning has transformed how jet tagging, a critical classification task at high-energy particle colliders such as the CERN Large Hadron Collider (LHC), is performed, leading to a drastic improvement in its performance in the past few years. In this talk, Dr. Qu will go through recent progress in deep learning approaches for jet tagging and their applications in Higgs boson studies and new physics searches at the LHC. Prospects and possible future directions will also be discussed.<\/p>\n\n\n\n Bio<\/strong>: Dr. Huilin Qu is a Senior Research Fellow at CERN. He received his B.S. degree from Peking University in 2014, and Ph.D. from University of California, Santa Barbara in 2019. His research has focused on searches for new physics and measurements of the Higgs boson properties with the CMS experiment at the CERN LHC, particularly using novel approaches and advanced techniques such as machine learning. He played a key role in searches for the Higgs boson decaying to a pair of charm quarks, for Higgs boson pair production in the high-momentum regime, and for supersymmetric partners of the top quark. In addition, Huilin is active in machine learning research for jet physics. He proposed a series of novel deep-learning approaches for jet tagging, which substantially improved the performance and have been widely adopted at the LHC and beyond.<\/p>\n\n\n\n 07\/20\/2022:<\/strong> Paving a data-centric high-way for materials science\uff08\u6570\u636e\u9a71\u52a8\u6750\u6599\u79d1\u5b66\uff09, Prof. Miao Liu<\/p>\n\n\n\n\n\n Abstract<\/strong>: In this talk, the speaker will be presenting how he takes all the technologies that have disrupted other industries and start to disrupt his own.

With the maturity of the methods, the developments of user-friendly codes, and the increase of high-performance computer power, the atomistic ab initio methods, especially the methods based on density functional theory, have been used in every aspect of material research. It is not a common practice to simulate systems with hundreds of atoms. However, since the computational cost scales as the third power of the number of atoms, new strategies are needed to go beyond this barrier. Furthermore, a huge gap exists between the computable systems and many of the experimental systems, both in size scale and temporal scale. How to bridge this gap is a main challenge in order to bring the ab initio computation into industry. To overcome such challenges, we need to use multiple methods, including linear scaling method, machine leaning method, and new scheme for high performance computation. I will discuss some of these efforts in LongXun KuanTeng Inc.<\/p>\n\n\n\n Bio<\/strong>: Lin-Wang Wang: Chief scientist in Semiconductor Institute, CAS, and chief scientific advisor in LongXun Kuang Teng Inc. Senior Staff Scientist, Lawrence Berkeley National Laboratory, Berkeley, CA, U.S. 1999-2021. Dr. Wang has 30 years of experience in large scale electronic structure calculations. He has worked in O(N) electronic structure calculations in early 1990s. Worked with Alex Zunger, he invented the folded spectrum method which pushed the limit of non-self-consistent electronic structure calculations from 100 atoms to thousands of atoms. He developed a linear combination of bulk bands (LCBB) method for semiconductor heterostructure electronic structure calculations, which allows the calculation of million atom devices. He developed generalized moments method which calculates the density of state and optical absorption spectra of a given system without explicit calculation of its eigenstates. He also developed a popular parallel total energy plane wave pseudopotential program (PEtot). He invented a charge patching method, which enables the ab initio accuracy thousand atom calculations for nano systems. He has developed a linear scaling three-dimensional fragment method (LS3DF), which can be used to selfconsistently calculate systems with tens of thousands of atoms. Recently, he developed a new algorithm for real-time time-dependent DFT calculations which accelerates the traditional algorithms by hundreds of times.<\/p>\n\n\n\n 12\/14\/2021<\/strong>:<\/strong> Broadly neutralizing antibodies against SARS-CoV-2 variants\uff08\u9488\u5bf9SARS-CoV-2\u53d8\u79cd\u7684\u5e7f\u8c31\u4e2d\u548c\u6297\u4f53\uff09, Prof. Linqi Zhang<\/p>\n\n\n\n 12\/14\/2021<\/strong>:<\/strong> Structural insights into the infection and evolution of the highly pathogenic human coronaviruses\uff08\u9ad8\u81f4\u75c5\u6027\u4eba\u7c7b\u51a0\u72b6\u75c5\u6bd2\u611f\u67d3\u548c\u8fdb\u5316\u7684\u7ed3\u6784\u7814\u7a76\uff09, Prof. Xinquan Wang<\/p>\n\n\n\n
