Robust Contraction Decomposition For Minor-Free Graphs And Its Applications, Bandyapadhyay Sayan, William Lochet, Daniel Lokshtanov, Dániel Marx, Pranabendu Misra, Multiple Additional Authors

Computer Science Faculty Publications and Presentations

We prove a robust contraction decomposition theorem for H-minor-free graphs, which states that given an H-minor-free graph G and an integer p, one can partition in polynomial time the vertices of G into p sets Z₁,… ,Z_p such that tw(G/(Z_i ⧵ Z')) = O(p + |Z'|) for all i ∈ [p] and Z' ⊆ Z_i. Here, tw(⋅) denotes the treewidth of a graph and G/(Z_i ⧵ Z') denotes the graph obtained from G by contracting all edges with both endpoints in Z_i ⧵ Z'. Our result generalizes earlier results by Klein [SICOMP 2008] and Demaine et al. [STOC 2011] based …

Gene And Alleles Of Tyk2 (Rs11085727) And Tyk2 (Rs34536443) Polymorphisms In Covid-19 Patients Using Arms-Pcr., Thuraya Habeeb, Adnan Aubaid

Al-Qadisiyah Medical Journal

The clinical presentation of COVID-19 varies greatly from case to another, with host characteristics playing a pivotal role. The immune system is a pivotal function in establishing the course of SARS-COV-2 infection. Severe instances of COVID-19 and the resulting death are caused less by the virus itself than by the destructive unrestrained immune response. Among the host determinants for poor disease prognosis is probably genetic vulnerability to dysregulated immune response. The objective of this work is to examine some of the host genetic variables that are being studied in relation to the severity of COVID-19. The complex relationship between autoimmunity …

An Investigation Of Water-Based Cutting Fluids: Choline Amino Acid Protic Ionic Liquids As A Potential Sustainable Additive, Moni I. Chavez-Padilla

Theses

This comprehensive investigation examines the use of choline amino acid protic ionic liquids (CHAAPILs) as environmentally friendly additives for water-based cutting fluids (WBCFs) and showed a significant improvement in both friction and wear compared to traditional cutting fluids. Notably, water alone is ineffective as a boundary lubricant for aluminum machining promoting cyclic hydrolysis that generates brittle Al(OH)3 films while generating friction above dry sliding. As traditional petroleum-based lubricants are increasingly recognized for their detrimental environmental impact, the development of sustainable alternatives has become essential in the tribology community. CHAAPILs derived from renewable amino acids and choline sources were specifically formulated …
