Projector-Based Embedding Eliminates Density Functional Dependence for QM/MM Calculations of Reactions in Enzymes and Solution

Combined quantum mechanics/molecular mechanics (QM/MM) methods are increasingly widely utilized in studies of reactions in enzymes and other large systems. Here, we apply a range of QM/MM methods to investigate the Claisen rearrangement of chorismate to prephenate, in solution, and in the enzyme chorismate mutase. Using projector-based embedding in a QM/MM framework, we apply treatments up to the CCSD­(T) level. We test a range of density functional QM/MM methods and QM region sizes. The results show that the calculated reaction energetics are significantly more sensitive to the choice of density functional than they are to the size of the QM region in these systems. Projector-based embedding of a wave function method in DFT reduced the 13 kcal/mol spread in barrier heights calculated at the DFT/MM level to a spread of just 0.3 kcal/mol, essentially eliminating dependence on the functional. Projector-based embedding of correlated ab initio methods provides a practical method for achieving high accuracy for energy profiles derived from DFT and DFT/MM calculations for reactions in condensed phases

The Efficacy and Safety of Heterologous Immunization with Pfizer-BioNTech (Pfizer) to Individuals Who Have Completed A Primary Vaccination Schedule with Sinopharm (BBibp-CorV)

The aim of this study was to examine the effectiveness and potential adverse reactions when providing a different Pfizer-BioNTech booster shot to 235 volunteers who had previously received the BBIBP-CorV Sinopharm primary vaccination series. Between February and December 2022, a questionnaire-based cross-sectional study was conducted in Duhok, located within the Kurdistan Region of Iraq. The individuals included in the study were adults aged 18 and above, who had received a Pfizer-BioNTech booster shot following the completion of a two-dose vaccination regimen with Sinopharm (BBIBP-CorV). The findings revealed that among those vaccinated with BBIBP-CorV, there were breakthrough infections at a rate of 4.26%, and no significant correlation was identified between post-vaccination infections and factors such as demographics or medical history. Furthermore, individuals who had a Pfizer booster dose experienced breakthrough infections at a rate of 5.73%, and similarly, no link was discovered between this rate and demographic or medical factors. Additionally, the study uncovered that participants commonly experienced side effects, primarily consisting of mild effects at the injection site. The study implies that both the Sinopharm and Pfizer vaccines demonstrate satisfactory safety profiles. It also suggests that giving a heterologous booster dose to individuals who have finished their primary vaccination with the BBIBP-CorV vaccine offers a significant level of protection against infection

Prediction of Emerging Technologies Based on Analysis of the U.S. Patent Citation Network

The network of patents connected by citations is an evolving graph, which provides a representation of the innovation process. A patent citing another implies that the cited patent reflects a piece of previously existing knowledge that the citing patent builds upon. A methodology presented here (i) identifies actual clusters of patents: i.e. technological branches, and (ii) gives predictions about the temporal changes of the structure of the clusters. A predictor, called the {citation vector}, is defined for characterizing technological development to show how a patent cited by other patents belongs to various industrial fields. The clustering technique adopted is able to detect the new emerging recombinations, and predicts emerging new technology clusters. The predictive ability of our new method is illustrated on the example of USPTO subcategory 11, Agriculture, Food, Textiles. A cluster of patents is determined based on citation data up to 1991, which shows significant overlap of the class 442 formed at the beginning of 1997. These new tools of predictive analytics could support policy decision making processes in science and technology, and help formulate recommendations for action

Nano Mapper: an Internet knowledge mapping system for nanotechnology development

Nanotechnology research has experienced rapid growth in recent years. Advances in information technology enable efficient investigation of publications, their contents, and relationships for large sets of nanotechnology-related documents in order to assess the status of the field. This paper presents the development of a new knowledge mapping system, called Nano Mapper (http://nanomapper.eller.arizona.edu), which integrates the analysis of nanotechnology patents and research grants into a Web-based platform. The Nano Mapper system currently contains nanotechnology-related patents for 1976–2006 from the United States Patent and Trademark Office (USPTO), European Patent Office (EPO), and Japan Patent Office (JPO), as well as grant documents from the U.S. National Science Foundation (NSF) for the same time period. The system provides complex search functionalities, and makes available a set of analysis and visualization tools (statistics, trend graphs, citation networks, and content maps) that can be applied to different levels of analytical units (countries, institutions, technical fields) and for different time intervals. The paper shows important nanotechnology patenting activities at USPTO for 2005–2006 identified through the Nano Mapper system
