Repurposing hemoproteins for metal-catalyzed H atom transfer in asymmetric radical biocatalysis
Authors: Zhang Xiang , Chen Dongping , Ward Thomas
Published: November 2024

Transition metal–hydrides have been widely exploited in homogenous catalysis for hydrofunctionalization of unsaturated moieties, including carbonyls, alkenes and alkynes. As a complement to the well-established chemistry of these complexes involving heterolytic metal–hydride bond cleavage, metal–hydride hydrogen atom transfer (MHAT) has attracted increased interest, as it offers a promising strategy for radical hydrofunctionalziation of unactivated alkenes thus enabling late-stage diversification of complex molecules. However, due the weak interactions between the prochiral organic radical species and the enantiopure metal catalyst, achieving asymmetric MHAT remains challenging. Herein, we report our efforts to repurpose cytochrome P450 enzymes to catalyze asymmetric MHAT, a new-to-nature reaction. Directed evolution of the well-studied P450BM3 (CYP102A1) enzyme led to the identification of a triple mutant that catalyzes asymmetric MHAT radical cyclization of unactivated alkenes to afford diverse cyclic compounds, including pyrrolidines, in up to a 97:3 enantiomeric ratio under aerobic whole cell conditions. Mechanistic investigations support an MHAT mechanism proceeding via homolytic cleavage of a fleeting iron(III)hydride species. Directed evolution using CYP119 as hemoprotein scaffold led to the identification of a stereocomplementary MHATase, highlighting the potential of repurposed hemoproteins for MHAT biocatalysis. Our study showcases the potential of integrating abiotic metal–hydride activity into native metalloenzymes to expand the scope of asymmetric radical biocatalysis.

Published: November 2024

Light-energy conversion processes causing alternations in spin multiplicity are attracting attention, but the development of quantum sensing technology applicable to fluid environment such as inside cells has been unexploited. How to achieve efficient energy conversion with controlling spin quantum coherence in a noisy condensed system is challenging. In this study, we investigate the effect of molecular motion on electron spin polarization to control quantum information of three-spin qubits in fluid environment by using steric effects of organic molecules at room temperature. Using time-resolved electron paramagnetic resonance (TREPR) to observe the light-induced generation and transfer of quantum entanglement, we directly observed photoexcited quartet state generated in radical-chromophore coupled systems and clarified details of the electron spin polarization mechanism including decoherence effect by activation of anisotropic molecular motion by the steric effects.
Accurate and Affordable Simulation of Molecular Infrared Spectra with AIQM Models
Authors: Hou Yi-Fan , Wang Cheng , Dral Pavlo O.
Published: November 2024

Infrared (IR) spectroscopy is a potent tool for identifying molecular structures and studying the chemical properties of compounds, and hence, various theoretical approaches have been developed to simulate and predict the IR spectra. However, the theoretical approaches based on quantum chemical calculations suffer from high computational cost (e.g., density functional theory, DFT) or insufficient accuracy (e.g., semi-empirical methods orders of magnitude faster than DFT). Here, we introduce a new approach, based on the universal machine learning (ML) models of the AIQM series targeting CCSD(T)/CBS level, that can deliver molecular IR spectra with accuracy close to DFT (compared to the experiment) and the speed close to a semi-empirical GFN2-xTB method. This approach enables efficient interpretation of the IR bands by clearly assigning them to the vibrational normal modes in contrast to alternative ML models, which can only predict the spectra. Our implementations for calculating IR spectra with ML and quantum mechanical (DFT, semi-empirical, ab initio wavefunction) approaches are available in MLatom as described in https://github.com/dralgroup/mlatom.

Published: November 2024

Against the backdrop of published cryptic genetic diversity and partly resolved taxonomy of the Eutropis macularia complex of skinks in the Indian Peninsula, we reassess the taxonomic status of the Western Ghats populations. Based on our examination of name-bearing types of two synonymised nomina (Euprepes brevis, Lygosoma dawsoni) and a valid (Mabuya gansi) nomen, we recognise two species: E. brevis and E. dawsoni, with E. gansi being the synonym of the latter. We characterise and distinguish these southwest Indian taxa from the allopatric E. macularia s. str. In keeping with studies on the nearby island of Sri Lanka, cryptic diversity within the peninsular Indian E. macularia complex has resulted in the resurrection of these long-synonymised nominal taxa.

Authors: Govindaraj Divya , Senthikumar Natchiappan , Periyasamy Senthamarai Selvan
Published: November 2024

Uplands provide refuge for insects subject to lowland habitat loss, but information on their response to climate change is lacking particularly orthopterans. There is a significant reduction in the diversity of grasshoppers however a shift of highly mobile and polyphagous insects towards higher altitudes is prevalent, in the era of climate change. Our study on the diversity of grasshoppers in the Nilgiris shola forest supported that the shift of grasshopper from mid-altitude to high altitude. The high values of Shannonâ€™s diversity index (Hâ€™) were recorded in Nedugula (1.43) followed by Longwood (1.34) and Avalanche shola forests (1.29). The species distributed only in lowland forests are now recorded in the high altitudinal stunted wet evergreen shola forests. It is evident from our study that the upland forests provide refuges to highly mobile insects like grasshoppers when lowland sites have an impact on climatic fluctuations.

Authors: Yaman Şule , Yaman Mustafa
Published: November 2024

Boxwood (Buxus spp.), which is widespread all over the world except Antarctica and widely used in many areas, is threatened by Cydalima perspectalis (box tree moth). Cydalima perspectalis, which has become widespread in Europe, is a new invasive species originating from East Asia and has become widespread in Turkiye in the last ten years. This species was first observed in parks and gardens in Sarıyer, Istanbul, in 2011. Since then, it has continued to spread rapidly in Turkiye. The pest causes intense damage by causing drying on boxwood areas, which causes economic and ecological losses. The rich ecological and topographical conditions of Turkiye are also favorable for the spread of this species. Therefore, it is important to develop pest control methods and take early measures. Within the scope of this study, the aim was to realize early detection of Cydalima perspectalis in Turkiye and make a risk map in this context. For this purpose, a risk map was created by determining the risky areas where Cydalima perspectalis can spread in Turkiye using weighted overlay analysis from geographic information system (GIS) technologies. Existing boxwood locations obtained from field studies were compared with the risk map and analyzed. As a result of the analysis, the presence of Cydalima perspectalis was found in the boxwood in the identified risk areas, and it is expected to be transmitted in boxwood that is in the risk area but not observed to have Cydalima perspectalis. With this research, a risk map for Cydalima perspectalis was made for the first time.

Published: November 2024

Models of land use/land cover (LULC) are crucial for assessing changes in LULC, forecasting land use needs, and providing guidance for appropriate land use planning and management, especially in urban areas. Urban sprawl is one of the main causes of the erratic variation in LULC around the globe. In this study, we used the CA-ANN and Markov-Chain models to analyze the LULC simulation based on LULC patterns from previous decades as well as the directional changes of urban expansion in Sambalpur city. We used the random forest (RF) model and Landsat imagery to prepare LULC maps for the years 1992, 2002, 2012, and 2022 for better classification accuracy. The result showed that the overall accuracy and kappa values were 94.24%, 89%, 94%, and 90% and 0.92, 0.80, 0.90, and 0.85, respectively, for the selective years. Based on the transition matrix model (1992–2012), the LULC map of the year 2022 was obtained and validated, and subsequently, LULC maps for the years 2032 and 2042 were predicted with a Kappa value of 94.97% and 93.24%, respectively. The findings indicate that the largest proportion of bare land underwent conversion within the settlement area, with the highest degree of sprawl observed in the northwestern direction and 4-kilometer buffer zones. These findings define current and future patterns in LULC and offer vital information for planning and sustainable land use management in Sambalpur city.

Authors: Özbayrak Simla , İlçi Veli
Published: November 2024

Simultaneous localization and mapping (SLAM) is used in many fields to enable robots to map their surroundings and locate themselves in new circumstances. Visual-SLAM (VSLAM), which uses a camera sensor, and LiDAR-SLAM, which uses a light detection and ranging (LiDAR) sensor, are the most prevalent SLAM methods. Thanks to its benefits, including low-cost compared to LiDAR, low energy consumption, durability, and extensive environmental data, VSLAM is currently attracting much attention. This study aims to produce a three-dimensional (3D) model of an indoor environment using image data captured by the stereo camera located on the Unmanned Ground Vehicle (UGV). Easily measured objects from the field of operation were chosen to assess the generated model’s accuracy. The actual dimensions of the objects were measured, and these values were compared to those derived from the VSLAM-based 3D model. When the data were evaluated, it was found that the size of the object produced from the model could be varied by ±2cm. The surface accuracy of the 3D model produced has also been analysed. For this investigation, areas where the walls and floor surfaces were flat in the field were selected, and the plane accuracy of these areas was analysed. The plain accuracy values of the specified surfaces were determined to be below ±1cm.

It is difficult to find the exact meaning of education. School education is considered education, while somewhere the process from birth to death is considered education. Generally, the process of learning is also considered education. Education is not just me teaching and you accepting, but it is a process of development that goes on in both the teacher and the student. Education brings about a change in the behavior of a person, the theoretical basis of education is based on philosophy and philosophy is related to life, the way of living is called philosophy. Determination of objectives would be impossible without resorting to philosophy. Education is purposeful and various philosophies determine its objectives. Education is life in itself, hence life is also education, it contains interaction or interaction. While constantly struggling with the environment, he learned to live.

Existing climate prediction models are physics-based and use supercomputers to predict future climate evolution. Physics-based predictions require improved atmospheric models, which can be challenging to find and develop, and improving the fundamental resolution of simulations can be computationally demanding. Measuring rainfall around the world has many scientific and social benefits. These benefits include of the processes that cause global climate change, increased precipitation and hydrological processes, improved weather information, Better identification of severe storms, including predictions of storm size and landfall. The Global Precipitation Measure (GPM) has completed the work of defining the scientific and metric goals and framework needed to achieve those goals. Precipitation forecasting is the prediction of the amount and type of precipitation (rain, snow, sleet, etc.) that will fall in a specific location over a certain period of time. This is typically done using numerical weather prediction models, which take into a wide range of atmospheric and oceanic data to make predictions about the weather. Precipitation forecast is the process that predicts the possibility of weather conditions at an exact time and place. An artificial neural network is a type of machine learning model that can be used for long-term precipitation forecasting. This model is trained on a large amount of historical weather data and uses this data to predict future rainfall. Artificial neural networks can be used to model complex and linear relationships between atmospheric and oceanic variables and precipitation. The Model may help us in forecasting long-range precipitation, approximately before one month of monsoon season over Kabirdham.

Published: November 2024

Parking congestion has become a major problem in today's metropolitan environments, resulting in lost time, higher emissions, and irritated drivers. There is a significant lack of parking spots in large cities as a result of the expanding number of vehicles and the ever-increasing metropolitan population. In addition to making it difficult and time-consuming to find a parking space, this shortage has made pollution and traffic congestion worse. Conventional parking management methods are becoming less and less effective in addressing these issues because they usually depend on physical barriers or manual ticketing. Innovative approaches that combine automation and technology are getting more and more popular as a way to solve this problem. Conventional parking management systems often rely on human interaction and physical infrastructure, which leads to restricted scalability and inefficiency. On the other hand, adding deep learning methods and cutting-edge computer vision technologies to parking management opens up new possibilities for a smarter, more effective, and more user-friendly experience. This system makes use of two essential elements: automatically recognizing license plate numbers for vehicle identification and facial recognition technology for person identification. By seamlessly integrating these technologies, the system not only facilitates effortless parking but also enhances security and optimizes parking space utilization. In this survey, we will explore the fundamental components, benefits, and potential impact of the Face and Number Plate-Based Smart Parking System. Experimental results shows that improved efficiency in smart parking system using face and number plate verification system.
