Logistic Optimization For Multi Depots Loading Capacitated Electric Vehicle Routing Problem From Low Carbon Perspective, Xiaoning Zhu, Rui Yan, Zhaoci Huang, Wenchao Wei, Jiaqin Yang, Shamsiya Kudratova

Faculty and Staff Works

In this paper, a multi depots capacitated electric vehicle routing problem where client demand is composed of two-dimensional weighted items (2L-MDEVRP) is addressed. This problem calls for the minimization of the transportation distance required for the delivery of the items which are demanded by the clients, carried out by a fleet of electric vehicles in several depots. Since the 2L-MDEVRP is an NP-hard problem, a heuristic algorithm combined variable neighborhood search algorithm (VNS) and space saving heuristic algorithm (SSH) is proposed. The VNS algorithm is used to solve the vehicle routing problem (VRP) sub-problem, and the SSH algorithm is used …

Integrative Framework For Long-Term Activity Monitoring Of Small And Secretive Animals: Validation With A Cryptic Pitviper, Dominic L. Desantis, Vicente Mata-Silva, Jerry D. Johnson, Amy E. Wagler

Faculty and Staff Works

The use of miniature accelerometer (ACT) data-loggers for remote and continuous recording of animal movement behavior is becoming increasingly common. Until recently, size constraints limited most animal-borne ACT applications to large-bodied species. We capitalized on the ongoing miniaturization and advancement of these technologies and associated computational techniques to develop a framework for long-term, low-frequency ACT monitoring of activity in small and secretive terrestrial species. We achieved this by internally implanting coupled radio transmitters and tri-axial ACTs in rattlesnakes (Crotalus atrox). Periodic field-validation observations of behavior were used to train and test supervised learning models (Random Forest, RF; Generalized Linear Elastic …

Faculty and Staff Works

The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) satellite has detected in excess of 1000 sources in the ∼20-100 keV band during its surveys of the sky over the past 17 years. We obtained 5 ks observations of 15 unclassified INTEGRAL Gamma-Ray (IGR) sources with the Chandra X-ray Observatory in order to localize them, to identify optical/IR counterparts, to measure their soft X-ray spectra, and to classify them. For 10 of the IGR sources, we detect Chandra sources that are likely (or in some cases certain) to be the counterparts. IGR J18007-4146 and IGR J15038-6021 both have Gaia parallax distances, placing them …

Crystallography Case Studies At The Undergraduate Level, Peter Josue Rosado Flores

Faculty and Staff Works

Powder diffraction is not a characterization method alien when it concerns inorganic chemistry and material science. At the undergraduate level, however, it is rare to come upon the teaching of these methods (probably due to the lack of expensive instrumentation that could ascend the $500,000 USD mark), and instructors mostly focus on the theory. This work provides techniques to construct these case studies that could be utilized in a classroom environment, particularly at the intermediate and advance inorganic chemistry level. Therefore, the purpose of this study seeks to contribute implemented ideas to the facilitation of crystallography education at the undergraduate …

1h, 13c, 15n Resonance Assignments And Secondary Structure Of Yeast Oligosaccharyltransferase Subunit Ost4 And Its Functionally Important Mutant Ost4v23d, Bharat P. Chaudhary, David Zoetewey, Smita Mohanty

Faculty and Staff Works

Asparagine-linked glycosylation is an essential and highly conserved protein modification reaction that occurs in the endoplasmic reticulum of cells during protein synthesis at the ribosome. In the central reaction, a pre-assembled high-mannose sugar is transferred from a lipid-linked donor substrate to the side-chain of an asparagine residue in an -N-X-T/S- sequence (where X is any residue except proline). This reaction is carried by a membrane-bound multi-subunit enzyme complex, oligosaccharyltransferase (OST). In humans, genetic defects in OST lead to a group of rare metabolic diseases collectively known as Congenital Disorders of Glycosylation. Certain mutations are lethal for all organisms. In yeast, …

Structural Insight Into The Mechanism Of N-Linked Glycosylation By Oligosaccharyltransferase, Smita Mohanty, Bharat P. Chaudhary, David Zoetewey

Faculty and Staff Works

Asparagine-linked glycosylation, also known as N-linked glycosylation is an essential and highly conserved post-translational protein modification that occurs in all three domains of life. This modification is essential for specific molecular recognition, protein folding, sorting in the endoplasmic reticulum, cell–cell communication, and stability. Defects in N-linked glycosylation results in a class of inherited diseases known as congenital disorders of glycosylation (CDG). N-linked glycosylation occurs in the endoplasmic reticulum (ER) lumen by a membrane associated enzyme complex called the oligosaccharyltransferase (OST). In the central step of this reaction, an oligosaccharide group is transferred from a lipid-linked dolichol pyrophosphate donor to the …

Exposure To Phthalates Impaired Neurodevelopment Through Estrogenic Effects And Induced Dna Damage In Neurons, Shisan Xu, Huan Zhang, Ping Chieh Pao, Audrey Lee, Jun Wang, Yu Suen Chan, Francis A.M. Manno, Shun Wan Chan, Shuk Han Cheng, Xueping Chen

Faculty of Science & Technology (THEi)

© 2020 The Authors Phthalates are commonly used in plastic products in daily life. The endocrine-disrupting effects of phthalates have been widely reported. Accumulating evidence from human cohorts and lab animals indicate exposure to phthalates might impair neurodevelopment. However, the direct causal relationship and mechanism between phthalates with neurodevelopment and neurotoxicity have not been firmly established. We found that phthalates (i.e. DBP, DINP, BBP) disrupted the expression of estrogen receptors (esr1, esr2a, esr2b), and impaired neurogenesis in the brain of zebrafish during embryonic development. Moreover, the abnormal expression of estrogen receptors, especially esr2a, was partly rescued in zebrafish which exposed …

Spectrum-Based Pushover Analysis For The Quick Seismic Demand Estimation Of Reinforced Concrete Shear Walls, Yang Liu, J. S. Kuang, Qunxian Huang, Zixiong Gu, Xueying Wang

Faculty of Science & Technology (THEi)

© 2020 Institution of Structural Engineers In the design of medium- and high-rise buildings, the reinforced concrete (RC) shear wall structure is widely used to resist seismic loading. Thus, accurately predicting the seismic demand of this structural form becomes particularly important. However, existing multi-mode pushover analysis methods are mainly applied to predicting seismic demands of frame structures, while few attentions have been paid on other structural forms. In this paper, by revising the equation for predicting the overall roof displacement, the spectrum-based pushover analysis (SPA) of RC shear wall structures for the fast prediction of the seismic demand is presented. …

Data For Paper "Separating Thermal And Viscous Effects Of Temperature On Copepod Respiration And Energy Budget", Abigail Tyrell, Nicholas Fisher, David Fields

SoMAS Research Data

Changes in temperature alter the viscosity of fluids, which impacts the force needed to move and the diffusion rates of gases. This is particularly salient for organisms that operate at mid to low Reynolds numbers. In this study, we investigated the independent effects of changes in temperature and viscosity on oxygen consumption rates of two coastal copepods (Acartia tonsa and Parvocalanus crassirostris) and used bioenergetic models to predict how these patterns could influence copepods in the natural environment. We found that only temperature influenced copepod oxygen consumption rates, indicating that copepods were not impacted by reduced oxygen diffusivity …
