Faculty, Staff and Student Publications

Anticancer immunity is predicated on leukocyte migration into tumors. Once recruited, leukocytes undergo substantial reprogramming to adapt to the tumor microenvironment. A major challenge in the field is distinguishing recently recruited from resident leukocytes in tumors. In this study, we developed an intravascular Ab technique to label circulating mouse leukocytes before they migrate to tissues, providing unprecedented insight into the kinetics of recruitment. This approach unveiled the substantial role of leukocyte migration in tumor progression using a preclinical mouse model of lung adenocarcinoma. Regulatory T cells (Tregs), critical mediators of immunosuppression, were continuously and rapidly recruited into tumors throughout cancer …

A High Step-Up Parallel Boost/Quasi-Z-Source Pwm Dc-Dc Converter For Photovoltaic Applications, Mahdi Rezvanyvardom

Emirates Journal for Engineering Research

In this article, a novel DC-DC converter is proposed, which is derived from the parallel combination of a conventional boost converter and a Quasi-Z-Source converter. This converter benefits from the features of both mentioned converters. Compared to similar structures, the proposed converter has a suitable gain. This is due to the parallel combination of two voltage-boosting structures, namely boost and Quasi-Z-Source. The simple and linear circuit operation of the converter is another advantage. On the other hand, the control circuit of the converter is also simple and can be designed as PWM. Due to the Quasi-interleaved structure at the input …

Text-To-Model Transformation: Natural Language-Based Model Generation Framework, Aditya Akundi, Joshua Ontiveros, Sergio Luna

Mechanical Engineering Faculty Publications

System modeling language (SysML) diagrams generated manually by system modelers can sometimes be prone to errors, which are time-consuming and introduce subjectivity. Natural language processing (NLP) techniques and tools to create SysML diagrams can aid in improving software and systems design processes. Though NLP effectively extracts and analyzes raw text data, such as text-based requirement documents, to assist in design specification, natural language, inherent complexity, and variability pose challenges in accurately interpreting the data. In this paper, we explore the integration of NLP with SysML to automate the generation of system models from input textual requirements. We propose a model …

Graphics Processing Units (GPUs) are the accelerator of choice in a variety of application domains, because they can accelerate massively parallel workloads and can be easily programmed using general-purpose programming frameworks such as CUDA and OpenCL. Each Streaming Multiprocessor (SM) contains an L1 data cache (L1D) to exploit the locality in data accesses. L1D misses are costly for GPUs for two reasons. First, L1D misses consume a lot of energy as they need to access the L2 cache (L2) via an on-chip network and the off-chip DRAM in case of L2 misses. Second, L1D misses impose performance overhead if the …

Behind The Curtain: Recommendations For Neurodiversity Research, Andree Koehler

The Qualitative Report

Researchers have explored neurodiversity in terms of gender, gender identity and expression, masking, and more, yet the focus is often on neurodiversity as synonymous with autism. There remains a challenge to expand the body of neurodiversity research that is broader than autism. In my article, neurodiversity will be discussed as an element of the broad human condition, rather than a singular state or condition of impairment isolated to a portion of the population to delineate the paradigm based on neurological variations from medical and social models. This paper was designed to offer a “how to” for conducting research into neurodiversity …

Method Of Selecting The Optimal Variant Of Mine Closure With The Possibility Of Capturing Methane From Underground Excavations, Marian Turek, Małgorzata Magdziarczyk

Journal of Sustainable Mining

The article presents a method of selecting the optimal option for the closure of a coal mine, from which it is planned to capture the methane remaining in the goaf and deposit it for many years for its economic use. Using the example of several options for the closure of one of the mines, for which the evaluation criteria have been defined, and the weights of their relevance have been determined, it is described how to create a special algorithm for the selection of the optimal option.
