We report measurements of the branching fractions of singly Cabibbo-suppressed decays Λc+→pη and Λc+→pπ0 using the full Belle data sample corresponding to an integrated luminosity of 980.6 fb-1. The data were collected by the Belle detector at the KEKB e+e- asymmetric energy collider. A clear Λc+ signal is seen in the invariant mass distribution of pη. The fitted number of signal events of the Λc+→pη process is 7734±263; from this, we measure the ratio of branching fractions B(Λc+→pη)/B(Λc+→pK-π+)=[2.258±0.077(stat)±0.122(syst)]×10-2, from which we infer the branching fraction B(Λc+→pη)=[1.42±0.05(stat)±0.11(syst)]×10-3. In addition, no significant signal for Λc+→pπ0 is found, so an upper limit on …


Non-Linear Dimensionality Reduction Using Auto-Encoder For Optimized Malaria Infected Blood Cell Classifier, Aayush Dhakal Apr 2021

Non-Linear Dimensionality Reduction Using Auto-Encoder For Optimized Malaria Infected Blood Cell Classifier, Aayush Dhakal

Honors Theses

Neural Networks have been widely used in the problem of Medical Image Analysis. However, when dealing with large images, deep networks easily exhaust computer resources, which in turn hinders training. This paper shows the efficacy of using Auto-Encoders as a dimensionality reduction tool to increase the efficiency of a Malaria Infected Blood Cell Image classifier. We show that using an autoencoder, we can reduce the dimensionality of large blood cell images effectively such that the features in the new space retain all the essential information from the original input. Then we show that the new features obtained from the autoencoder …

Tractorcade: Investigating The Relationship Between Group Theory And The American Agriculture Movement's Attempt At Policy Change, Hanna M. Metzler Apr 2021

Tractorcade: Investigating The Relationship Between Group Theory And The American Agriculture Movement's Attempt At Policy Change, Hanna M. Metzler

Honors Theses

This thesis aims to investigate the relationship between The American Agriculture Movement (AAM) and group theory, with a focus on AAM’s usage of Tractorcade as a tool to promote policy change. Gathering data through a myriad of sources - including existing literature, oral histories, newspaper articles, documents, and journal entires - this thesis analyzes AAM’s Tractorcade demonstration as a social movement aimed at influencing policy change. Utilizing Charles Tilly’s worthiness, unity, numbers, and commitment (WUNC) social movement framework, we find that although AAM employed strong unity and numbers, they failed in displaying substantial worthiness or commitment, ultimately leading to a …

Do Autocratic Regimes Excel In Natural Disaster Relief? A Case Study Of Political Institutions And Covid-19 Exposure, Jane Kay Apr 2021

Do Autocratic Regimes Excel In Natural Disaster Relief? A Case Study Of Political Institutions And Covid-19 Exposure, Jane Kay

Honors Theses

The COVID-19 pandemic of 2020 has challenged what we know about the politics of public health. In this research study, I investigate the COVID-19 pandemic as a natural disaster and hypothesize if authoritarian governments are more adequate at disaster control and relief. I hypothesize that the more autocratic a government structure, the better they would be at handling COVID-19 exposure and outbreaks due to their centralized decision making, unified media, and their ability to make unpopular decisions without repercussions. In order to test this theory, I gather data from the Johns Hopkins database for three key dates in the pandemic …

Gorgonians Are Foundation Species On Sponge-Dominated Mesophotic Coral Reefs In The Caribbean, Marc Slattery, Michael P. Lesser Apr 2021

Gorgonians Are Foundation Species On Sponge-Dominated Mesophotic Coral Reefs In The Caribbean, Marc Slattery, Michael P. Lesser

Faculty and Student Publications

Foundation species (FS) regulate ecological processes within communities often facilitating biodiversity and habitat complexity. Typically FS are dominant structure-forming taxa; but less dominant taxa having disproportionate ecological impacts to the community can also be FS. Mesophotic coral ecosystems (MCEs) are deep coral reef (∼30–150 m) communities, often dominated by emergent sponges in the Caribbean Basin. Despite the potential competitive advantage of sponges on MCEs, gorgonians are also common constituents of these reefs. Data from the Bahamas demonstrate increased biodiversity and densities of sponges on mesophotic reefs with gorgonians relative to reefs without these species. Drawing upon fifteen years of field …

Babu, P. Behera, J. Bennett, M. Bessner, V. Bhardwaj, B. Bhuyan, T. Bilka, J. Biswal, G. Bonvicini, A. Bozek

Faculty and Student Publications

We present a search for the dark photon A′ in the B0 → A′A′ decays, where A′ subsequently decays to e+e−, μ+μ−, and π+π−. The search is performed by analyzing 772 × 106BB¯ events collected by the Belle detector at the KEKB e+e− energy-asymmetric collider at the ϒ(4S) resonance. No signal is found in the dark photon mass range 0.01 GeV/c2 ≤ mA′ ≤ 2.62 GeV/c2, and we set upper limits of the branching fraction of B0 → A′A′ at the 90% confidence level. The products of branching fractions, ℬ(B0→A′A′)×ℬ(A′→e+e−)2 and ℬ(B0→A′A′)×ℬ(A′→μ+μ−)2, have limits of the order of 10−8 depending …


Influence Of Bulk And Surface Interactions From Thick, Porous, Soil-Based Substrates On The Spreading Behavior Of Different Viscosity Oils, Firoz Ahmed, Brenda Hutton-Prager Apr 2021

Influence Of Bulk And Surface Interactions From Thick, Porous, Soil-Based Substrates On The Spreading Behavior Of Different Viscosity Oils, Firoz Ahmed, Brenda Hutton-Prager

Faculty and Student Publications

Crude oils and motor oils are commonly identified in oil spills on land. Controlling and understanding their flow both across and into land is of paramount importance to minimize spread and subsequent damage to the ecosystem. Spreading kinetics and surface energy studies were conducted with these oils over several realistic soil-based matrixes, consisting of topsoil (silt-dominant), sand, clay, and moisture. Spreading area through a 1.3 cm deep matrix was reduced with increased moisture content, densely packed matrixes, and higher viscosity oils. Initial contact angle (CA) measurements for all oils was typically lower on clay matrixes due to its sheet-like structure …
