Modeling steel corrosion in concrete structures - part 2: A unified adaptive finite element model for simulation of steel corrosion

Recently, numerical methods that can reliably predict the service life of reinforced concrete structures have attracted increasing attention. In this, the second of two companion papers, relevant literature on numerical modeling of steel corrosion is first reviewed. Then, a unified and straight-forward algorithm that is capable of performing different types of steel corrosion modeling using a single scheme is presented, based on the new inverse relation relating the current density with potential for the cathodic reaction proposed in the companion paper. Besides being significantly more efficient computationally arising from the selective mesh refinement feature of adaptive finite element modeling, the proposed algorithm can also efficiently model complex geometries and incorporate parameters that vary over the domain.© 2010 by ESG

Modeling steel corrosion in concrete structures - part 1: A new inverse relation between current density and potential for the cathodic reaction

Corrosion of steel reinforcement can seriously compromise the service life of reinforced concrete structures. Hence, service life prediction and enhancement of concrete structures under corrosion attack are of significant importance. As a result, numerical methods that can reliably predict the service life of concrete structures have attracted increasing attention. In this, the first of two companion papers, a simple and significantly improved inverse relation relating the current density with potential for the cathodic reaction is proposed. This enables the current densities to be determined accurately from the measured potentials. Equally importantly, the proposed inverse relation also enables the efficient and straight-forward nonlinear algorithm for modeling of steel corrosion in concrete structures to be developed. Such an algorithm is presented in the companion paper of this. © 2010 by ES

BeWith: A Between-Within Method to Discover Relationships between Cancer Modules via Integrated Analysis of Mutual Exclusivity, Co-occurrence and Functional Interactions

The analysis of the mutational landscape of cancer, including mutual exclusivity and co-occurrence of mutations, has been instrumental in studying the disease. We hypothesized that exploring the interplay between co-occurrence, mutual exclusivity, and functional interactions between genes will further improve our understanding of the disease and help to uncover new relations between cancer driving genes and pathways. To this end, we designed a general framework, BeWith, for identifying modules with different combinations of mutation and interaction patterns. We focused on three different settings of the BeWith schema: (i) BeME-WithFun in which the relations between modules are enriched with mutual exclusivity while genes within each module are functionally related; (ii) BeME-WithCo which combines mutual exclusivity between modules with co-occurrence within modules; and (iii) BeCo-WithMEFun which ensures co-occurrence between modules while the within module relations combine mutual exclusivity and functional interactions. We formulated the BeWith framework using Integer Linear Programming (ILP), enabling us to find optimally scoring sets of modules. Our results demonstrate the utility of BeWith in providing novel information about mutational patterns, driver genes, and pathways. In particular, BeME-WithFun helped identify functionally coherent modules that might be relevant for cancer progression. In addition to finding previously well-known drivers, the identified modules pointed to the importance of the interaction between NCOR and NCOA3 in breast cancer. Additionally, an application of the BeME-WithCo setting revealed that gene groups differ with respect to their vulnerability to different mutagenic processes, and helped us to uncover pairs of genes with potentially synergetic effects, including a potential synergy between mutations in TP53 and metastasis related DCC gene

Asian American Studies and the Fight for Worker Justice

This essay explores higher education–labor partnerships in the contemporary era between Asian American Studies (AAS), the Asian Pacific American Labor Alliance (APALA), and AAS community partnerships. With the intensified attacks on workers, unions, and Asian American, Pacific Islander, and other communities of color, the importance of higher education and labor and community partnerships will be a valuable resource to expand critical research and participatory education. These partnerships embody the community studies’ roots of AAS. Using three case studies, this essay highlights these partnerships and concludes with a discussion of the opportunities and challenges students can experience when working in labor union spaces and recommendations for building university-labor partnerships
