New Thermoelectric Materials, G. Abdurakhmanov, K Mukimov, A Esbergenova, S. Mamatqulova
Euroasian Journal of Semiconductors Science and Engineering
Recent achievements in developing of thermoelectric materials of higher efficiency are reviewed. It is shown that these achievements are based on decreasing of thermal conductivity down to values typical for materials having disordered or nanoscale structure. On the other hand these achievements demonstrate that there is no any principal limit for efficiency of thermoelectric devices beyond the Carnot formula.

© 2020 authors. Published by the American Physical Society. We search for lepton-number- and baryon-number-violating decays τ-→p¯e+e-, pe-e-, p¯e+μ-, p¯e-μ+, p¯μ+μ-, and pμ-μ- using 921 fb-1 of data, equivalent to (841±12)×106 τ+τ- events, recorded with the Belle detector at the KEKB asymmetric-energy e+e- collider. In the absence of a signal, 90% confidence-level upper limits are set on the branching fractions of these decays in the range (1.8-4.0)×10-8. We set the world's first limits on the first four channels and improve the existing limits by an order of magnitude for the last two channels.
Using Contextualized Materials To Teach English Grammar, Jingyi Yang
Using Contextualized Materials To Teach English Grammar, Jingyi Yang
Master's Projects and Capstones
Grammar learning is the foundation of language learning. Despite its importance, many ESL adult learners consider grammar learning a challenging part, and the effectiveness of grammar instruction has been evaluated low. This is because of inappropriate teaching approaches and the lack of contextualized learning materials. Inappropriate teaching approaches include traditional PPP (Presentation, Practice, Production), which hinder the effectiveness of research-based teaching approaches. Decontextualized and meaningless grammar forms are additional underlying challenges of grammar learning. This field project uses task-based language teaching (TBLT) as a theoretical framework. The three literature review themes explore the importance and challenges of grammar, grammar instruction …
The Relationship Between Spatial Ability And The Conservation Of Matter In Middle School, Merryn Cole, Jennifer Wilhelm, Briana Marie-Mcknight Vaught, Corinne Fish, Hailey Fish
The Relationship Between Spatial Ability And The Conservation Of Matter In Middle School, Merryn Cole, Jennifer Wilhelm, Briana Marie-Mcknight Vaught, Corinne Fish, Hailey Fish
Teaching and Learning Faculty Research
Research has shown that spatial ability plays a key role in understanding STEM (Science, Technology, Engineering, and Mathematics) content, including chemistry. Conservation of Matter (CoM) is an essential but challenging topic for chemistry students of all ages to grasp; it is often taught in a way where students memorize it but do not learn what it means conceptually. This research explored the relationship between understanding spatial ability and conceptual understanding of CoM in middle school students. CoM was examined in two ways using the Conservation of Matter Assessment (CoMA): through questions on conservation of atoms and the conservation of mass. …

We use neutron scattering to investigate spin excitations in Sr(Co1-xNix)2As2, which has a c-axis incommensurate helical structure of the two-dimensional (2D) in-plane ferromagnetic (FM) ordered layers for 0.013=x=0.25. By comparing the wave vector and energy dependent spin excitations in helical ordered Sr(Co0.9Ni0.1)2As2 and paramagnetic SrCo2As2, we find that Ni doping, while increasing lattice disorder in Sr(Co1-xNix)2As2, enhances quasi-2D FM spin fluctuations. However, our band structure calculations within the combined density functional theory and dynamic mean field theory (DFT+DMFT) failed to generate a correct incommensurate wave vector for the observed helical order from nested Fermi surfaces. Since transport measurements reveal increased …

This study developed a mathematical model following the fundamental principles of mass transfer for the simulation of the oil and moisture content change during the Deep-Fat Frying of plantain (ipekere) chip. The explicit Finite Difference Technique (FDT) was used to conduct a numerical solution to the consequential governing equation (partial differential equation) that was used to describe the mass transfer rate during the process. Computer codes that were computed in MATLAB were used for the implementation of FDT at diverse frying conditions. Samples of the plantain were cut into portions of 2 mm thickness, and these sliced portions …

Rapid advances in artificial intelligence have made it possible to produce forgeries good enough to fool an average user. As a result, there is growing interest in developing robust methods to counter such forgeries. This study presents a new Fourier spectrum-based method for detecting forged text in video images. The authors' premise is that brightness distribution and the spectrum shape exhibit irregular patterns (inconsistencies) for forged text, while appearing more regular for original text. The method divides the spectrum of an input image into sectors and tracks to highlight these effects. Specifically, positive and negative coefficients for sectors and tracks …
Charge Nurse Orientation, Angela Zafke
Charge Nurse Orientation, Angela Zafke
Nursing Capstones
Traditional undergraduate training focuses heavily on clinical skills with minimal emphasis on leadership. In practice, a nurse with clinical prowess is often promoted to the charge nurse position. Taking on the leadership role of a charge nurse can be a stressful experience without proper training and preparation that leads to burnout and turnover. With more experienced nurses facing retirement, now is the time to prepare future nursing leaders. This starts with adequately preparing a nurse to lead within the unit in the charge nurse role. A comprehensive literature review was conducted regarding charge nurse orientation. Charge nurse competencies were not …

Student Works (2020-2029)
Deoxyribonucleic acid (DNA) has attracted a lot of attention lately owing to the discovery of its semiconducting property and is considered as an interesting material that could find applications in nanotechnology and electronic devices. In-depth understanding of its charge transfer mechanism is however required for effective development of DNA-based technology. This unfortunately remains still a non-trivial task despite the numerous theoretical and experimental studies that have been conducted to date. The complexity of the previously employed methods, and their lack of accuracy has made it difficult to grasp the clear understanding of the electronic behaviors of the DNA molecules under …

Defensive Publications Series
For large-scale Low-Power and Lossy Networks (LLNs), communications between nodes in different Personal Area Networks (PANs) (i.e., inter-PAN communications) typically have to traverse long routing paths, even for cases in which two nodes may be located physically close to each other. Techniques herein provide a novel mechanism to improve inter-PAN communications by utilizing the nodes that are located at the boundary of PANs.

In other words, it is required to show that the "science intensity" of the lo- gistics business is a capitalized asset.
Is Environmentalism The Right Strategy To Decarbonize The World?, Marco Marini, Ornella Tarola, Jacques-Francois Thisse
Is Environmentalism The Right Strategy To Decarbonize The World?, Marco Marini, Ornella Tarola, Jacques-Francois Thisse
Fondazione Eni Enrico Mattei Working Papers
We study how the supply of environmentalism, which is defined by psychic benefits (costs) associated with the purchase of high-environmental (low-environmental) qualities, affects the way firms choose their products and the ensuing consequences for the global level of pollution. Contrary to general belief, a high supply of environmentalism does not give rise to a better environmental outcome because it endows firms with more market power which they use to maximize profits. By contrast, standard policy instruments such as a minimum quality standard or the use of greener technologies leads to a better ecological footprint.

Leveraging The Inductive Bias Of Large Language Models For Abstract Textual Reasoning, Christopher Michael Rytting
Leveraging The Inductive Bias Of Large Language Models For Abstract Textual Reasoning, Christopher Michael Rytting
Theses and Dissertations
Large natural language models (such as GPT-2 or T5) demonstrate impressive abilities across a range of general NLP tasks. Here, we show that the knowledge embedded in such models provides a useful inductive bias, not just on traditional NLP tasks, but also in the nontraditional task of training a symbolic reasoning engine. We observe that these engines learn quickly and generalize in a natural way that reflects human intuition. For example, training such a system to model block-stacking might naturally generalize to stacking other types of objects because of structure in the real world that has been partially captured by …

Faculty Publications
In this study, three magnetic ionic liquids (MILs) were investigated for extraction of four estrogens, i.e., estrone (E1), estradiol (E2), estriol (E3), and ethinylestradiol (EE2), from environmental water. The cation trihexyl(tetradecyl)phosphonium ([P66614]+), selected to confer hydrophobicity to the resulting MIL, was combined with tetrachloroferrate(III), ferricyanide, and dysprosium thiocyanate to yield ([P66614][FeCl4]), ([P66614]3[Fe(CN)6]), and ([P66614]5[Dy(SCN)8]), respectively. After evaluation of various strategies to develop a liquid-liquid microextraction technique based on synthesized MILs, we placed the MILs onto a magnetic stir bar and used them as extracting solvents. After extraction, the MIL-enriched phase was dissolved in methanol and injected into an HPLC-UV for …
