Photon isolation and jet substructure
… a new photon isolation criterion inspired by jet substructure techniques. Soft drop isolation is collinear-safe and is equivalent to Frixione isolation at leading order in the small R limit. However, soft drop isolation has the interesting feature of being democratic, meaning that photons can be …

Antimalarials based on the arylpiperazine privileged substructure
Based on a previous study, arylpiperazines (2-chlorophenylpiperazine, 2-ethoxyphenylpiperazine and phenylpiperazine) were found to be significantly more potent against the chloroquine-resistant (K1) strain than against the chloroquine-sensitive(DIO) strain. In other studies, …

Jet substructure at the Large Hadron Collider
… we use the CMS Open Data to study the 2-prong substructure of jets. We use CMS's particle flow reconstruction algorithm to obtain jet constituents, which we then use to perform various jet substructure studies. After validating our basic kinematics and substructure results through a comparison …

A substructure synthesis formulation for vibration isolation
… method presented here is classified as a substructure synthesis (SS) technique. The distinction between the new SS method and the component mode synthesis formulation is that no transformation between local coordinates and generalized coordinates occurs in the new SS method. The advantage …

Probing local group galactic substructure with cosmological simulations
… cosmological parameters affect dark matter halo substructure. I find that the process of continuous sub-halo accretion and destruction leads to a steady state description of most subhalo properties in a given host, unchanged by small fluctuations in cosmological parameters. Subhalo concentration, …

Density-based clustering of information networks by substructure optimization
… poorly. We investigate whether clustering within substructures of the MSF can improve the result. We present a new set of similarity measures for weighted networks that allow the MSF to connect vertices that are not connected in the original network. We convert the MSF to a hierarchy and merge it …

Decoding Copy Number Substructure and Evolution From Single Cell Genomics
… We show that CopyKit can resolve the clonal substructure of two metastatic liver samples. We also apply CopyKit to determine the metastatic lineages of a primary breast tumor with metastasis to the liver and pleural effusion and two matched colorectal carcinoma and its matched metastatic …

Weak lensing flexion as a probe of galaxy cluster substructure
… total masses and the amount of dark matter substructure within galaxy cluster haloes is a fundamental probe of the ACDM model of structure formation, as well as the interactions between baryonic and non-baryonic matter. In this thesis I approach the topic of cluster mass structure in two …

A study of x-ray substructure in rich clusters of galaxies
A comparison of three tests to determine substructure in rich Abell clusters of galaxies was preformed and the results are presented in this paper. The data used are ROSAT PSPC X-ray images of a sample of 21 clusters drawn from the ACO catalog, and a subset of the ESO Nearby Abell Cluster Survey …

Dº decays from e+e- collisions: precision, rare and substructure results
Three analyses of D0 meson decays are presented which use the data collected with the CLEO II detector at the Cornell Electron Storage Ring. First, a precision measurement of the ratio of the Dº → K-π+πº branching fraction to that of Dº → K-π+ is performed resulting in the best measurement to date. …

Explorations of the quark substructure of the nucleon in lattice QCD
… thesis presents two lattice studies of the quark substructure of nucleons. The first study used overlaps calculated on the lattice to evaluate the goodness of trial nucleon sources. A variational study was performed to find the trial source that best approximated the true nucleon ground state. In …

Monolithic and partitioned Rosenbrock-based time integration methods for dynamic substructure tests
… the test structure is divided onto two substructures: the relatively crucial substructure is tested physically and the other is modelled numerically in the computer. The key challenge is to ensure that both substructures interact in real-time, in order to simulate the behaviour of the …

D(0) Decays From Electron-Positron Collisions: Precision, Rare and Substructure Results
Three analyses of D0 meson decays are presented which use the data collected with the CLEO II detector at the Cornell Electron Storage Ring. First, a precision measurement of the ratio of the D0 → K-pi +pi0 branching fraction to that of D 0 → K-pi+ is performed resulting in the best …

Substructure Synthesis Analysis and Hybrid Control Design for Buildings under Seismic Excitation
We extend the application of the substructure synthesis method to more complex structures, and establish a design methodology for base isolation and active control in a distributed model of a building under seismic excitation. Our objective is to show that passive and active control complement each …

Gravitationally lensed image simulations for the study of the substructure in galaxy clusters
… clusters. We are particularly interested in the substructure of dark matter in galaxy clusters as it signals constraints on various cosmological parameters as well as cluster evolution. Gravitationally lensed image simulations are needed in order to determine just how much can be learned from …
