Multidisciplinary “Boot Camp” Training in Cellular Bioengineering to Accelerate Research Immersion for REU Participants
No full textResearch Experiences for Undergraduates (REU) sites widely serve as the first major research gateway for undergraduates seeking a structured research experience. Given their lack of prior research skills, and the highly compressed duration of the REU programs, these students frequently encounter barriers to a seamless transition into a new laboratory environment. We hypothesized that the design of a unified short course on laboratory and analysis techniques could serve as a pivotal orientation experience. Our goal was to rapidly align student expertise to their summer research goals while also integrating the student participants into a cohesive learning community. This article discusses the design and outcomes of a Cellular Bioengineering Boot Camp, which is offered at the outset of the 10-week REU site at Rutgers. The Boot Camp provides hands-on, supervised training for techniques and procedures that are common among projects. The training establishes a common language and baseline for the REU students and allows their first laboratory experiences to be with each other, and creates an immediate network of peers and mentors. Surveys before and after the Boot Camp and at the end of the summer indicated a significant improvement in student proficiency in the techniques that was retained throughout the summer. We believe that the Boot Camp approach can be tailored to the specifics of each REU site and its associated projects and research foci.Peer reviewe
Gender and technology in the East Midlands boot and shoe industry : 1850-1911
No full textMany scholars now consider that gender is an important category in historical study,
but unfortunately many do not practice what they preach. Feminists have recognised
for some time the importance of some form of historical analysis to feminism, or at
least what Judith Allen calls 'a historically grounded feminism'. The protagonists in
the debate disagree considerably, however, over the methodology which feminist
historians should adopt. The various positions taken up have led to a schism between
those who believe the feminist challenge to mainstream, or what Elizabeth Fox-
Genovese calls 'official' history, should be mounted from within the discipline of
history or from outside it. Judith Allen claims that the work which has been done in
women's history to date serves to raise considerable doubt that accepting the
discipline of history as presently constituted is a viable option for feminism. She sees
the phallocentric characteristics of history as an obstacle to feminists using history.
Allen feels that 'no less than Marxism, feminism is opposed by professional historians
as an ahistorical grid of abstraction and prescription, threatening the integrity of the
historical evidence.
Lessons Learned from NSF I-Corps Boot Camp
No full textAudience Response System, (ARS), has proven its values as a tool to enhance students' engagement and participation in the classroom. Since 2011, the author was working on to creating a web based application, Click2Text, to incorporate cell phones and smart phones in traditional and online classes to replace ARS. Several web-based solutions were tested and launched, however, it was hard to convince fellow faculty members for its adoption. It is also a known fact that most academic researchers in universities and college have little or no previous knowledge of entrepreneurial process nor do they possess the entrepreneurial mindset and related skills. So, when in the winter of 2016, the author was presented with an opportunity to participated in the NSF I-Corps introduction to customer discovery course, boot camp at Wayne State University, it was seen as a great opportunity to learn entrepreneurial process and skill. This paper documents how I-Corps boot camp helped in refining author’s research on Click2Text by identifying right customer segments and their needs and using them to create feature list that will eventually contribute to popularizing Click2Text within the university. The study also document lessons learned that would help new and young academic researchers making the intelligent decision of choosing to participate in I-Corps activities and how to get the most benefit of the boot camp.

Model checking boot code from AWS data centers
No full text© 2020, The Author(s). This paper describes our experience with symbolic model checking in an industrial setting. We have proved that the initial boot code running in data centers at Amazon Web Services is memory safe, an essential step in establishing the security of any data center. Standard static analysis tools cannot be easily used on boot code without modification owing to issues not commonly found in higher-level code, including memory-mapped device interfaces, byte-level memory access, and linker scripts. This paper describes automated solutions to these issues and their implementation in the C Bounded Model Checker (CBMC). CBMC is now the first source-level static analysis tool to extract the memory layout described in a linker script for use in its analysis
Identifying hardware during boot-time system verification
No full textThesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2017.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 85-90).Modern systems measure the software loaded at boot-time to ensure the machine starts in a trusted state. Such measurements, however, do not include any information about the underlying hardware of the machine. Recent DRAM-based attacks and the growing complexity of the supply chain attest to the importance of measuring hardware at boot. In this thesis, we propose a technique for designing measurement schemes for hardware components. We then apply this technique to designing and implementing a hardware measurement scheme for DRAM on a real system without hardware modifications. Finally, we evaluate our DRAM hardware measurement scheme and demonstrate that it achieves 89% accuracy in mapping a DRAM measurement to the manufacturing process from which that DRAM was produced.by Berj Krikor Chilingirian.M.

A Research-Based Study of Spring Boot Security: Mathematical Modeling and Analysis of JWT Authentication
No full textA Research-Based Study of Spring Boot Security: Mathematical Modeling and Analysis of JWT Authentication is a study, a practical and research-based thesis of Spring Boot Security and a mathematical formula implemented in a security algorithm. This Thesis contains an in-depth analysis and study of Spring Boot security with a clear understanding of security algorithms along with mathematical methods, a case study, and post-quantum. The thesis includes breaking down complex code into a mathematical solution, creating a robust, deep understanding of how security, encoding/decoding, and password hashing work, which results in making the backend secure and authenticated.
The paper has three primary divisions: case studies, research theory, and practical approaches. The case study section focuses on the analysis of several real-world security breaches to identify their main causes: misconfigurations, weak credential management, and routine mistakes. The research-theory section is therefore an intensive study of different types of attacks, crypto graphic algorithms, token structures, and the very basic concepts of authentication, authorization, and validation. In this regard, it also deals with advanced topics like quantum computing, Bloch sphere theory, Mosca’s theorem, the workflow of algorithms, and their related mathematical formulations. It suggests possible strategies for security threats and methods that would enhance the security of Spring Boot applications. Finally, the section on practical approaches goes on to illustrate the practical side of things: the implementation of mathematical expressions, algorithmic functions, and code examples with including post-quantum configuration in Spring Boot.
The main aim of this thesis is to provide a comprehensive study of the mathematical expression behind the coding line and cryptographic algorithms. Additionally, the author's aim is to aware security threats due to a lack of developer practices and possible solutions to overcome those situations. Additionally, the author is addressing potential threats that might arise during the evolution of quantum computing by explaining achievable post-quantum core information and configuration in Spring Boot. Finally, the author aims to demonstrate how mathematical expression and post-quantum configurations can be effectively applied
Ski Boot Soles Based on a Glass Fiber/Rubber Composite with Improved Grip on Icy Surfaces
No full textAbstractA study on the effect of glass fibers/rubber composites on the grip on ice has been conducted in order to develop new materials for ski boot soles with increased grip in winter environments. The study has been conducted analyzing the friction of a composite material and of a ski boot sole containing an insert made of the composite material and comparing the results with those obtained using rubber and a thermoplastic elastomer. The analysis of the morphology of the composite surface, by Scanning Electron Microscopy, shows a homogenous distribution of glass fibers of approximately 10μm of diameter in the rubber matrix. Moreover, the measure of the contact angle shows that the composite material has a higher water repellency compared to the rubber matrix. The measure of the coefficient of friction indicates a significant effect of the glass fibers on the grip on icy surfaces. The increased grip can be ascribed to the stiffness of the glass fibers that are able to have a mechanical grip on the ice surface and to the increased contact angle and water repellency of the composite that decrease the formation of a water layer below the sole
Transversus Abdominis Plane Block (TAP Block) Boot Camp
No full textAbstract Introduction Transversus abdominis plane (TAP) blocks are increasingly popular to manage postoperative pain. Because the target structure of the block is the neuro-fascial plane between the internal oblique muscle (IOM) and the transverse abdominis muscle rather than a single neural structure, this block is ideal to introduce novices to ultrasound-guided regional anesthesia. Methods This simulation-based introduction boot camp to ultrasound-guided regional anesthesia has been made mandatory for all anesthesia residents in our large North American academic institution. This resource provides learners the opportunity to learn the technical skills associated with ultrasound-guided needle placement, abdominal wall anatomy (i.e., muscles, nerves, vessels, peritoneum, and colon), and how to safely perform a bilateral ultrasound guided TAP block. Results Since the implementation of this resource, the author have observed that attending physicians appreciate that new residents have had a chance to practice this skill in a simulation lab. Simultaneously, residents greatly appreciate the structured introduction into regional anesthesia in the relaxed setting of the simulation lab, devoid of time constraints. Discussion TAP blocks are an ideal procedure for introducing anesthesiology residents to ultrasound-guided regional anesthesia during boot camp
