Harvey Mudd College is a private residential liberal arts college of science, engineering, and mathematics, founded in 1955 and located in Claremont, California, United States. It is one of the institutions of the contiguous Claremont Colleges, which share adjoining campus grounds.Harvey Mudd College shares university resources such as libraries, dining halls, health services, and campus security, with the other institutions in the Claremont Colleges, including Pitzer College, Scripps College, Claremont McKenna College, Pomona College, Claremont Graduate University, and Keck Graduate Institute of Applied Life science, but each college is independently managed by its own faculty, board of trustees, and college endowment and has its own separate admissions process. Students at Harvey Mudd are encouraged to take classes at the other four Claremont colleges, especially classes outside their major of study. Together the Claremont Colleges provide the resources and opportunities of a large university while enabling the specialization and personal attention afforded by the individual colleges. The Bachelor of Science diploma received at graduation is issued by Harvey Mudd College.The college is named after Harvey Seeley Mudd, one of the initial investors in the Cyprus Mines Corporation. Although involved in the planning of the new institution, Mudd died before it opened. Harvey Mudd College was funded by Mudd's friends and family, and named in his honor. Wikipedia.

In this paper, properly tuned damped absorbers are used to suppress excess vibration anywhere along an arbitrarily supported, damped Euler-Bernoulli beam during forced harmonic excitations. This vibration suppression is achieved by enforcing distinct nodes, or points of zero vibration, at desired locations along the beam. Instead of directly solving for the absorber parameter, which is highly computationally intensive, an efficient method is developed whereby the restoring forces exerted by the damped absorbers are first determined using Gaussian elimination. These restoring forces are then used to tune the parameters of the damped oscillators. Numerical experiments show that by inducing nodes at the appropriate locations, a region of nearly zero vibration amplitudes can be enforced, effectively quenching vibration in that segment of the beam. © 2012 American Society of Mechanical Engineers.

The alternative sigma factor RpoS controls a large regulon that allows E. coli to respond to a variety of stresses. Mutations in rpoS can increase rates of nutrient acquisition at the cost of a decrease in stress resistance. These kinds of mutations evolve rapidly under certain laboratory conditions where nutrient acquisition is especially challenging. The frequency of strains lacking RpoS in natural populations of E. coli is less clear. Such strains have been found at frequencies over 20% in some collections of wild isolates. However, laboratory handling can select for RpoS-null strains and may have affected some of these strain collections. Other studies have included an unknown diversity of strains or only used a phenotypic proxy as a measure of RpoS levels. We directly measured RpoS levels in a collection of E. coli that includes the full diversity of the species and that was handled in a manner to minimize the potential for laboratory evolution. We found that only 2% of strains produce no functional RpoS. Comparison of these strains in multiple labs shows that these rpoS mutations occurred in the laboratory. Earlier studies reporting much higher levels of RpoS polymorphism may reflect the storage history of the strains in laboratories rather than true frequency of such strains in natural populations.

This paper elaborates and formalizes the opening remarks made by the chair of the organizing committee at a recent workshop on innovation and entrepreneurship. Held at Harvey Mudd College in May 2011, and supported by HMC's Center for Design Education and the National Science Foundation, Mudd Design Workshop VIII provided a forum for engineers and designers - in their rolesas educators, researchers, and practitioners interested in learning and in design - to identify and articulate important aspects of innovation and entrepreneurship in design and engineering education. The remarks summarized below were intended to bring to the community's attention the entrepreneurs who developed and implemented some truly innovative ideas in engineering education. Many of these ideas are now 'best practices,' yet the innovators themselves are largely unrecognized. The story of these ideas and their originators also serve to remind us, as members of engineering faculties, that all too often we are remiss in maintain our institutional memories and passing down our own history. © 2012 TEMPUS Publications.

The social hymenopterans (ants, wasps and bees) have all the enzymatic and genetic mechanisms necessary for the functional modification of DNA by methylation. Methylation appears to play a central role in shaping the developmental processes that give rise to the different castes. However, could DNA methylation have other roles in social insects? Theoretical arguments predict that male and female hymenopterans can be in conflict over the reproductive potential of their female offspring. An exciting prospect for future research is to examine the possibility that queens and males imprint the genomes of their gametes using DNA methylation to manipulate the reproductive potential of their progeny in ways that favour the inclusive fitness of the parent. © 2012 Elsevier Ltd.

Abstract for proposal 1559403 PI: Lori Bassman

Proposal Title: IRES: US-Australia collaboration on new high strength, high ductility classes of high entropy alloys through intermetallic manipulation
Institution: Harvey Mudd College

Traditional alloys used in engineering applications consist primarily of one or two elements, with other elements added in relatively small quantities to enhance material properties. However, the inclusion of large quantities of additional elements typically causes alloys to become brittle. Recent work, including that by American undergraduate students working with researchers at the University of New South Wales (UNSW) in Australia and Prof. Lori Bassman of Harvey Mudd College (HMC), has led to the development of novel metal alloys using a new strategy. These advanced alloys, called high entropy alloys (HEAs), have carefully selected compositions with approximately equal amounts of several elements and have demonstrated excellent material properties. This project will greatly expand the range of combinations of elements that can be used to create successful HEAs. With the proposed new strategy will come increased promise for creating alloys with improved combinations of strength, ductility and cost. During ten week periods in the summers of 2017 to 2019, twelve undergraduate students will conduct experimental and computational research at UNSW towards this goal. The lead collaborators, Dr. Kevin Laws and Prof. Michael Ferry in the UNSW School of Materials Science and Engineering, and researchers in the UNSW Electron Microscope Unit have worked with HMC undergraduates for many years. They will continue to provide students with discipline-specific expertise and mentoring unavailable at HMC as well as extensive access to physical metallurgy laboratories, microscope facilities and training.

Progress in the HEA field so far has focused on identification of specific systems of elements that can form one or two simple solid solution phases with high thermal stability and no brittle intermetallic phases. In this project new HEAs will be developed by increasing the ductility of intermetallic phases that occur in other systems. Through this alloy development, the students and their UNSW mentors will refine the fundamental principles that govern HEA formation and atomic ordering and explore the deformation mechanisms associated with greatly enhanced strength and ductility in HEAs over conventional alloys. The specific experimental projects to be performed by HMC undergraduates include alloy design, alloy fabrication, mechanical characterization and microstructural characterization. Computational projects will involve first-principles modeling of alloy structures and properties. These experiences will contribute to the maturation of the students into confident, enthusiastic researchers who are prepared for science and engineering careers in international research environments. At least half of the participating students will be female, and underrepresented minority students will be specifically recruited.

This research is funded by the IRES program of the NSF Office of International Science and Engineering.
