Noncovalent Bonds Through Sigma And Pi-Hole Located On The Same Molecule. Guiding Principles And Comparisons, Wiktor Ziekiewicz, Mariusz Michalczyk, Steve Scheiner
Chemistry and Biochemistry Faculty Publications
Over the last years, scientific interest in noncovalent interactions based on the presence of electron-depleted regions called σ-holes or π-holes has markedly accelerated. Their high directionality and strength, comparable to hydrogen bonds, has been documented in many fields of modern chemistry. The current review gathers and digests recent results concerning these bonds, with a focus on those systems where both σ and π-holes are present on the same molecule. The underlying principles guiding the bonding in both sorts of interactions are discussed, and the trends that emerge from recent work offer a guide as to how one might design systems …

Large-Scale Cultivation Of Seaweed Is Effective Approach To Increase Marine Carbon Sequestration And Solve Coastal Environmental Problems, Yufeng Yang, Hongtian Luo, Qing Wang, Zhili He, Aimin Long
Bulletin of Chinese Academy of Sciences (Chinese Version)
All countries in the world are paying attention to low-carbon and carbon neutrality to achieve the mitigation of climate warming by reducing CO2 emissions. Ocean is the largest carbon pool on the earth and play an important role of carbon neutrality. More than half of the biological carbon on the earth is achieved by marine organisms. Among them, seaweed resources are abundant, with advantages such as low cost, high yield, measurable carbon sink, and strong cultivation controllability. Industrialized blue carbon can be formed offshore, which is a sustainable model for future development in coastal ecosystems. In addition, large-scale cultivation of …

Strategic Approach For Mariculture To Practice “Ocean Negative Carbon Emission”, Jihong Zhang, Jihua Liu, Yongyu Zhang, Gang Li
Bulletin of Chinese Academy of Sciences (Chinese Version)
Reducing CO2 emissions and increasing carbon sinks are basic approaches to achieve carbon neutralization in China. China is the largest mariculture country in the world. China's mariculture industry is dominated by non-fed culture type and characterized by rich species, diverse nutrition levels, and advanced farming technology. Therefore, mariculture has huge potential for the development of ocean negative carbon emissions (ONCE). However, the ONCE process of bivalves and seaweed farming is complicated, and the scientific principles, process, mechanisms, monitoring and evaluating methods, and approaches of increasing carbon sink are gradually being recognized and yet to be resolved. This study discusses the …

Blue Carbon Sink Function Of Chinese Coastal Wetlands And Carbon Neutrality Strategy, Faming Wang, Jianwu Tang, Siyuan Ye, Jihua Liu
Bulletin of Chinese Academy of Sciences (Chinese Version)
Coastal wetlands are the main body of the coastal "blue carbon (C)" ecosystem, and their "blue C" and ecosystem service function are important ocean-based climate change governance methods, which is a "nature-based solution". Chinese coastal wetlands are dominated by salt marshes, with little area of mangroves, while the area of unvegetated tidal flats is large. According to conservative estimation, the current C sequestration of coastal wetlands through sediment burial in China reaches to 0.97 Tg C·a-1, and would increase to 1.82-3.64 Tg C·a-1 at the end of this century. To achieve the commitment of "C neutrality" in 2060, China should …

Coral Reefs: Potential Blue Carbon Sinks For Climate Change Mitigation, Tuo Shi, Xinqing Zheng, Han Zhang, Qifang Wang, Xin Zhong
Bulletin of Chinese Academy of Sciences (Chinese Version)
Coral reefs are one of the most productive, and yet most vulnerable marine ecosystems. The global decline of coral reefs induced by climate change and human activities has already affected the processes of coral calcification and carbon cycling in the reef ecosystem, intensifying the long-standing CO2 "source-sink" debate over coral reefs. Despite the fact that coral calcification is accompanied by the release of CO2 to the atmosphere, the significance of coral reefs as a carbon sink cannot be ignored, given the complex biogeochemical processes in the reef ecosystem and the characteristic mixotrophic lifestyle of the reef-building corals. From the perspective …

Advocating Eco-Engineering Approach For Ocean Carbon Negative Emission, Yuze Wang, Yun Lu, Jihua Liu, Chuanlun Zhang
Bulletin of Chinese Academy of Sciences (Chinese Version)
Micro-organisms such as bacteria, archaea, and viruses are an immense invisible driving force behind the ocean carbon cycle and play a pivotal role in global climate change. Atmospheric CO2 is transformed into depositing organic components with the help of marine planktonic organisms which act as a biological pump (BP). The labile organic components are then transformed into recalcitrant organic carbon (RDOC) through the action of bacteria, archaea, and other organisms and viruses, which are called the microbial carbon pump (MCP). RDOC can be stored over thousands of years in the water column and the accompanying particulate organic matter can further …

Development Mechanism And Trading Mode Of Marine Carbon Sink, Yun Zhao, Yue Qiao, Liwei Zhang
Bulletin of Chinese Academy of Sciences (Chinese Version)
Marine carbon sink is one of the important methods to solve the problem of carbon emission in China. Under the dual constraints of economic development demand and ecological capacity, more policy means need to be explored to achieve carbon emission peak and carbon neutrality in China. There is great potential for the construction of marine carbon sink in China. Hence it is of great significance to build an integrated carbon sink system by combining marine carbon sink with land carbon sink. In the path to achieve marine carbon sequestration increase based on marine ecological improvement, marine breeding, coastal wetland protection …

Parallel Arbitrary-Precision Integer Arithmetic, Davood Mohajerani
Parallel Arbitrary-Precision Integer Arithmetic, Davood Mohajerani
Electronic Thesis and Dissertation Repository
Arbitrary-precision integer arithmetic computations are driven by applications in solving systems of polynomial equations and public-key cryptography. Such computations arise when high precision is required (with large input values that fit into multiple machine words), or to avoid coefficient overflow due to intermediate expression swell. Meanwhile, the growing demand for faster computation alongside the recent advances in the hardware technology have led to the development of a vast array of many-core and multi-core processors, accelerators, programming models, and language extensions (e.g. CUDA, OpenCL, and OpenACC for GPUs, and OpenMP and Cilk for multi-core CPUs). The massive computational power of parallel …

Recent advances in natural language processing have enabled automation of a wide range of tasks, including machine translation, named entity recognition, and sentiment analysis. Automated summarization of documents, or groups of documents, however, has remained elusive, with many efforts limited to extraction of keywords, key phrases, or key sentences. Accurate abstractive summarization has yet to be achieved due to the inherent difficulty of the problem, and limited availability of training data. In this paper, we propose a topic-centric unsupervised multi-document summarization framework to generate extractive and abstractive summaries for groups of scientific articles across 20 Fields of Study (FoS) in …
Telsam-Target Protein Fusions Can Form Diffraction-Quality Crystals Without Direct Inter-Polymer Contacts, Moriah Longhurst
Telsam-Target Protein Fusions Can Form Diffraction-Quality Crystals Without Direct Inter-Polymer Contacts, Moriah Longhurst
Undergraduate Honors Theses
X-ray diffraction is a robust method for determining the detailed 3D structures of specific proteins. However, this requires the formation of well-ordered protein crystals, a process that is time-consuming, expensive, and only has about a 10-30% success rate. New methods are needed to enable the efficient crystallization of challenging proteins. One such technique is explored here, which utilizes a protein polymer (the sterile alpha motif domain of the human protein translocation Ets leukemia, or TELSAM) as a crystallization chaperone to form a more ordered crystal lattice of target proteins and drive crystallization. This method was successfully used to crystallize, collect …

Electrochemical oxygen reduction reaction (ORR) is an important energy-related process requiring alternative catalysts to expensive platinum-based ones. Although recently some advancements in carbon catalysts have been reported, there is still a lack of understanding which surface features might enhance their efficiency for ORR. Through a detailed study of oxygen adsorption on carbon molecular sieves and using inelastic neutron scattering, we demonstrated here that the extent of oxygen adsorption/interactions with surface is an important parameter affecting ORR. It was found that both the strength of O2 physical adsorption in small pores and its specific interactions with surface ether functionalities in the …

Holocene Records Of Nebraska Mammals, Hugh H. Genoways
Zea E-Books Collection
A survey of the archeological and paleontological literature allowed a compilation of Holocene records of mammals in Nebraska. This survey identified Holocene records from 338 sites in 62 of the 93 Nebraska counties. These counties were located throughout state, but there was a concentration of sites in southwestern Nebraska where there were 27 fossil sites in Frontier County and 22 in Harlan County. Fossils sites were underrepresented in the Sand Hills region. Records of fossil mammals covered the entire Holocene period from 13,000 years ago until AD 1850. A minimum of 57 species (with eight additional species potentially present) representing …

Aminoacyl-tRNA synthetases (AARS) participate in decoding the genome by catalyzing conjugation of amino acids to their cognate tRNAs. During evolution, biochemical and environmental conditions markedly influenced the sequence and structure of the 20 AARSs, revealing adaptations dictating canonical and orthogonal activities. Here, we investigate the function of the appended Zn2+-binding domain (ZBD) in the bifunctional AARS, glutamyl-prolyl-tRNA synthetase (GluProRS). We developed GluProRS mutant mice by CRISPR-Cas9 with a deletion of 29 C-terminal amino acids, including two of four Zn2+-coordinating cysteines. Homozygous ZBD mutant mice die before embryonic day 12.5, but heterozygous mice are healthy. ZBD disruption profoundly reduces GluProRS canonical …

Heterogeneous content-based traffic distribution motivates Information-Centric Networking (ICN), where content delivery is of primary interest as a prominent solution. However, current work does not address Quality of Service (QoS) provisioning for prioritized traffic, which is required for different applications and content types. This paper extends ICN with data delivery deadline awareness and shapes the forwarding decisions to ensure prioritized packet treatment. The proposed QoS Aware-ICN (QoSA-ICN) classifies requests' priority with their QoS requirements by codifying a QoSInfo object in interest/data packets. QoSA-ICN also extends the existing NDN transmission mode to a converged best route with multi-hop multi-route forwarding, to avoid …

Seismic Attenuation, Time Delays And Raypath Bending Of Teleseisms Beneath Uturuncu Volcano, Bolivia, Alexandra K. Farrell
Seismic Attenuation, Time Delays And Raypath Bending Of Teleseisms Beneath Uturuncu Volcano, Bolivia, Alexandra K. Farrell
USF Tampa Graduate Theses and Dissertations
A set of 14 teleseismic earthquakes was studied to determine how wave propagation was affected by a presumed magma body beneath Uturuncu volcano, Bolivia. Teleseisms are suitable for study because they are relatively long period, contain purely P waves, and have near-vertical incidence angles. The number of events is small but the events have good signal-to-noise ratios and very similar waveforms for each event so that reliable measurements could be made of arrival times and amplitudes. Attenuation of amplitudes occurs in a NW-SE trend beneath the volcano, 14 by 34 km (long axis NW-SE). Calculated values of the quality factor …
