Observation Of Self-Patterned Defect Formation In Atomic Superfluids–From Ring Dark Solitons To Vortex Dipole Necklaces, Hikaru Tamura, Cheng-An Chen, Chen-Lung Hung

Purdue University Libraries Open Access Publishing Fund

Unveiling nonequilibrium dynamics of solitonic and topological defect structures in a multidimensional nonlinear medium is a current frontier across diverse fields. One of the quintessential objects is a ring dark soliton (RDS), whose dynamics are expected to display remarkable interplay between symmetry and self-patterned topological defect formation from a transverse (snake) instability, but it has thus far evaded full experimental observations. Here, we report an experimental realization of RDS generation in a two-dimensional atomic superfluid trapped in a circular box. By quenching the confining box potential, we observe an RDS emitted from the edge and its peculiar signature in the …

Who Gets The Whip? How Supplier Diversification Influences Bullwhip Effect In A Supply Chain, Tyler N. Burrows Sep 2023

Who Gets The Whip? How Supplier Diversification Influences Bullwhip Effect In A Supply Chain, Tyler N. Burrows

Theses and Dissertations

Emergent technologies, such as the `blockchain,' are enabling unprecedented coordination across firms in Supply Chains (SC). Firm decision-makers ultimately are going to need to understand how they can control (and optimize) such a network of relationships. However, the study of SC-level behavior leaves many open questions. Current approaches typically assume a focal firm, and the modeling of SC behavior is usually limited to single-product serial networks. In contrast, real-world SCs show that often a firm has many suppliers, even for the same raw material. This paper aims to understand how demand disturbances (e.g. the 'bullwhip effect') propagate and intensify throughout …

N-Terminal Α-Amino Sumoylation Of Cofilin-1 Is Critical For Its Regulation Of Actin Depolymerization, Weiji Weng, Xiaokun Gu, Yang Yang, Qiao Zhang, Qi Deng, Jie Zhou, Jinke Cheng, Michael X Zhu, Junfeng Feng, Ou Huang, Yong Li Sep 2023

N-Terminal Α-Amino Sumoylation Of Cofilin-1 Is Critical For Its Regulation Of Actin Depolymerization, Weiji Weng, Xiaokun Gu, Yang Yang, Qiao Zhang, Qi Deng, Jie Zhou, Jinke Cheng, Michael X Zhu, Junfeng Feng, Ou Huang, Yong Li

Faculty, Staff and Student Publications

Small ubiquitin-like modifier (SUMO) typically conjugates to target proteins through isopeptide linkage to the ε-amino group of lysine residues. This posttranslational modification (PTM) plays pivotal roles in modulating protein function. Cofilins are key regulators of actin cytoskeleton dynamics and are well-known to undergo several different PTMs. Here, we show that cofilin-1 is conjugated by SUMO1 both in vitro and in vivo. Using mass spectrometry and biochemical and genetic approaches, we identify the N-terminal α-amino group as the SUMO-conjugation site of cofilin-1. Common to conventional SUMOylation is that the N-α-SUMOylation of cofilin-1 is also mediated by SUMO activating (E1), conjugating (E2), …

Architectural Engineering

Designing a net Zero Energy Building nZEB envelope with high thermal comfort and low energy consumption is vital nowadays. There is some established specialized software for building optimization design, but these programs are time-consuming, expensive, and demand many data input of building parameters. Therefore, it is difficult to follow the optimization procedure. The aim of this research is to present a novel study to optimize the use of Phase Change Material PCM on opaque building envelope using a multi-objective optimization tool.

The Effect Of Using Ipad Apps In Developing Components Of Cooperative Learning Among Students During The Covid-19 Pandemic, Ayesha Alktebi

All Works

The purpose of this research is to investigate the effects of iPad use in the enhancement of structure and factors of interactional education among students during the COVID-19 pandemic. In this respect, the educational community that emphasized using interactional traditional methods imposed social distancing due to rapid global changes in recent years and the COVID-19 pandemic. This directly affected the traditional educational methods, and many students were deprived of the positive effects of interactional education. For all the aspects of education to achieve their goals, electronic applications were used in education to fully accomplish the results of public education and …
