We measure the branching fraction and time-dependent CP-violating asymmetry for B0 → J=ψπ0 decays using a data sample of 711 fb⁻¹ collected on the ϒ(4S) resonance by the Belle experiment running at the KEKB e⁺e⁻ collider. The branching fraction is measured to be B(B⁰ → J/_ψπ⁰) ¼ [1.62 ± 0.11(stat) ± 0.06(syst) × 10⁻⁵, which is the most precise measurement to date. The measured CP asymmetry parameters are S =−0.59 ±0.19(stat) 0.03(syst) and A = −0.15 ± 0.14(stat) ^+0.04 _−0.03 (syst). The mixing-induced CP asymmetry (S) differs …

Nonlocal Symmetries For Time-Dependent Order Differential Equations, Andrei Ludu

Publications

A new type of ordinary differential equation is introduced and discussed: time-dependent order ordinary differential equations. These equations are solved via fractional calculus by transforming them into Volterra integral equations of second kind with singular integrable kernel. The solutions of the time-dependent order differential equation represent deformations of the solutions of the classical (integer order) differential equations, mapping them into one-another as limiting cases. This equation can also move, remove or generate singularities without involving variable coefficients. An interesting symmetry of the solution in relation to the Riemann zeta function and Harmonic numbers is observed.

The Propagation Of Active-Passive Interfaces In Bacterial Swarms, Alison E. Patteson, Arvind Gopinath, Paulo E. Arratia

Physics - All Scholarship

Propagating interfaces are ubiquitous in nature, underlying instabilities and pattern formation in biology and material science. Physical principles governing interface growth are well understood in passive settings; however, our understanding of interfaces in active systems is still in its infancy. Here, we study the evolution of an active-passive interface using a model active matter system, bacterial swarms. We use ultra-violet light exposure to create compact domains of passive bacteria within Serratia marcescens swarms, thereby creating interfaces separating motile and immotile cells. Post-exposure, the boundary re-shapes and erodes due to self-emergent collective flows. We demonstrate that the active-passive boundary acts as …

Social Change For A Global Problem, Isabella Catalano

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Recently, the United Nations' International Panel on Climate Change (IPCC) released a new report[1], warning us that storms are becoming more volatile, sea surface temperatures are getting higher, global environment as a whole growing less predictable: in other words, things are about to get a whole lot worse than we predicted.

Unless, of course, we do something about it. The IPCC recommends cutting CO₂ emissions by 45% in order to curb just the worst of climate change's many effects.

There are a plethora of articles on the topic of just what, exactly, we as individuals can do: …

Recycling Just Got More Expensive. Can It Be Done Better?, Zachery Homolka

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

There was a time in history that America led the world in recycling. In World War Two, Americans were asked to recycle tin, steel, paper, and rubber for the war effort. The University of Southern Carolina states that children were so eager to participate, they went door to door collecting recyclable scraps to turn in to be made into tanks, planes, and ammunition. Yet, in 2017 the National Geographic estimated about 91% of plastic produced globally has not been recycled and instead is landfilled or littered into the environment. America is no longer leading the recycling charge, the World Economic …

“On-Bill Financing: A Bright Idea For Nebraska”, Lauren Taylor

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In over 29 states, a program called On-Bill Financing (OBF) is being utilized to improve the energy efficiency of homes and livelihoods of the people living in them. These programs have been implemented all over the country for many years, in states like Colorado, Hawaii, Iowa, and Michigan. According to the Environmental and Energy Study Institute (EESI), OBF has been wildly successful, reducing energy inefficiency, cutting energy bills, and improving the comfort of homes across the country with no upfront costs.

But what exactly is this mysterious money-saving program, and why hasn’t Nebraska tapped into it yet?

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The emerald ash borer was recently sighted in Lincoln, Nebraska this August. This was to be expected as they were also located in Douglas and Cass county. The emerald ash borer has been making its way west from Michigan and has also been detected in 61 counties in Iowa.

The emerald ash borer is a metallic green colored beetle that feeds on green ash, black ash, blue ash, and white ash trees. The insect can kill up to 99% of the ash trees that they come in contact with. The beetle is native to north-eastern Asia and is considered an …

Wave Energy In America, Chris Sukstorf

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The United States has an untapped energy goldmine: our shores. According to the National Oceanic and Atmospheric Administration (NOAA), the United States his home to over 95,000 miles of shoreline. This shoreline is home to beaches, homes, and wildlife, but it could be home to more: wave energy.

Wave energy comes in many forms: some use the bobbing up and down motion of waves to generate energy in a similar motion of a piston; others store water during high tide and then release it during low tide like a dam. All said and done, the United States has the ability …

Preface: Earth Observation For Integrated Water And Basin Management: Challenges For Adaptation To A Changing Environment, María J. Polo, Maria P. González-Dugo, Christopher M.U. Neale

Daugherty Water for Food Global Institute: Faculty Publications

Integrated river basin management involves a sound knowledge of water and land interactions, and impacts from and feedbacks to human activity. Remote sensing has been an efficient and increasingly promising means of gathering direct information of the Earth surface, as well as information on water and energy fluxes. The recent generation of high-resolution sensors offers a huge potential for monitoring, assessing, and modelling our changing environment in a context of uncertainty about how future climate conditions will affect the current water resource and basin management framework. Moreover, large amounts of data are now available posing a challenging opportunity to the …

Looking At The True Costs Of Environmental Degradation, Zachery Sehnert

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Progress is why we change, and innovation drives that progress. It is already very clear to scientists around the globe that our current framework for living is not sustainable. 97 percent of climate scientists are in consensus that there is a major threat to our ecosystem and action needs to be taken. Overpopulation, pollution, water scarcity, natural disasters, overfishing, deforestation are all issues that must be reevaluated with sustainability in mind. However only 49 percent of the general population share this belief, and even less, only 29 percent of CEOs are actively addressing climate change. The shortcoming for the general …

Nebraska’S Public Power Is Proof That Renewables Are (Literally) In The Public’S Best Interest, Jacob Monti

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Nebraska is the only state that has every electric utility publicly owned. This gives Nebraska a unique advantage of serving its customers rather than out-of-state shareholders. Since the goal is cheap power instead of profit margins and keeping shareholders happy, Nebraska rates are 16.8% below the national average. (EIA.gov)

So what does that mean for Renewable sources of electricity if cheap power is the main focus? Does cheap but dirty coal reign supreme?

Some might think that’d be a death blow for Renewables. Renewables (wind, solar, and hydro-electric power) are expensive and not profitable, right? WRONG.

Renewables make up just …

Side Chain Modifications To Improve Peptide Structure–Activity Relations, Neelam Lahankar

Seton Hall University Dissertations and Theses (ETDs)

While natural peptides, are ideal starting points for peptide-based drug design and development, they suffer from high conformational instability, which results in susceptibility to proteolytic degradation and poor bioavailability. Peptidomimetics in recent years has helped circumvent these shortcomings by improving the pharmacological properties of polypeptides. Peptidomimetics contain essential elements (pharmacophores) that mimic a natural peptide or protein in 3D space and retain the ability to interact with the biological target producing the same biological effect. In contrast, they offer conformationally restricted structures, potentially minimizing cross-target interactions, which leads to better transport properties through biologic membranes and resistance to immune responses. …

Lift On E15 Ban: Should Nebraskan Farmers Be Cheering?, Samantha Wattier

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The common gasoline-ethanol mixture available at gas station pumps is 10% ethanol (E10). The Environmental Protection Agency had a ban on 15% ethanol (E15) during summer months. The news has been covering the talks of President Trump to lifting this summer ban and supporters in Iowa are excited.

Should Nebraska shout Hoorah, too? It is common knowledge Nebraska is better than Iowa. We should be excited, too, right?! NO.

Iowa has been tracking Fuel Revenue sales including those from ethanol blends and has been pushing for the E15 ban lift. Considering Iowa produces MORE corn and MORE ethanol than …

Singularity Resolution In Anisotropic And Black Hole Spacetimes In Loop Quantum Cosmology, Sahil Saini

LSU Doctoral Dissertations

Loop quantum cosmology (LQC) has in recent years led to successful resolution of singularities in cosmological models while agreeing with general relativity in low curvature limit. Existence of a bounce and the possibility of an effective continuum description closely approximating the quantum evolution have been notable features of this singularity resolution. The effective spacetimes of loop quantized isotropic and Bianchi-I models have been shown to be geodesically complete and free from strong singularities. In this dissertation, we extend these results to effective loop quantized Bianchi-II, Bianchi-IX and Kantowski--Sachs models with arbitrary minimally coupled matter, and also explore the possibility of …

A new class of quiescent galaxies harboring possible AGN-driven winds has been discovered using spatially resolved optical spectroscopy from the ongoing SDSS-IV MaNGA survey. These galaxies, termed "red geysers," constitute 5%–10% of the local quiescent population and are characterized by narrow bisymmetric patterns in ionized gas emission features. Cheung et al. argued that these galaxies host large-scale AGN-driven winds that may play a role in suppressing star formation at late times. In this work, we test the hypothesis that AGN activity is ultimately responsible for the red geyser phenomenon. We compare the nuclear radio activity of the red geysers to …

Spoil Type Influences Soil Genesis And Forest Development On An Appalachian Surface Coal Mine Ten Years After Placement, Kenton L. Sena, Carmen T. Agouridis, Jarrod Miller, Christopher D. Barton

Lewis Honors College Faculty Publications

Surface mining for coal (or other mineral resources) is a major driver of land-use change around the world and especially in the Appalachian region of the United States. Intentional and well-informed reclamation of surface-mined land is critical for the restoration of healthy ecosystems on these disturbed sites. In Appalachia, the pre-mining land cover is predominately mixed hardwood forest, with rich species diversity. In recent years, Appalachian mine reforestation has become an issue of concern, prompting the development of the Forestry Reclamation Approach, a series of mine reforestation recommendations. One of these recommendations is to use the best available soil substitute; …

The Izu-Bonin-Mariana (IBM) fore arc preserves igneous rock assemblages that formed during subduction initiation circa 52 Ma. International Ocean Discovery Program (IODP) Expedition 352 cored four sites in the fore arc near the Ogasawara Plateau in order to document the magmatic response to subduction initiation and the physical, petrologic, and chemical stratigraphy of a nascent subduction zone. Two of these sites (U1440 and U1441) are underlain by fore-arc basalt (FAB). FABs have mid-ocean ridge basalt (MORB)-like compositions, however, FAB are consistently lower in the high-field strength elements (TiO2, P2O5, Zr) and Ni compared to MORB, with Na2O at the low …

Assessing Ground Penetrating Radar’S Ability To Image Subsurface Characteristics Of Icy Debris Fans In Alaska And New Zealand, Robert W. Jacob, Jeffrey M. Trop, R. Craig Kochel

Faculty Journal Articles

Icy debris fans have recently been described as fan shaped depositional landforms associated with (or formed during) deglaciation, however, the subsurface characteristics remain essentially undocumented. We used ground penetrating radar (GPR) to non-invasively investigate the subsurface characteristics of icy debris fans (IDFs) at McCarthy Glacier, Alaska, USA and at La Perouse Glacier, South Island of New Zealand. IDFs are largely unexplored paraglacial landforms in deglaciating alpine regions at the mouths of bedrock catchments between valley glaciers and icecaps. IDFs receive deposits of mainly ice and minor lithic material through different mass-flow processes, chiefly ice avalanche and to a lesser extent …

What is the largest possible reduction in Calvin College’s annual energy costs from a $5M initial investment in renewable energy? Renewable energy systems are essential for Calvin College to reduce greenhouse gas emissions and achieve carbon neutrality to meet the Carbon Commitment that President Le Roy signed in December 2017. Also, a significant cost reduction could be a positive result of transitioning to renewable energy sources such as geothermal, wind, solar, and biomass. Four renewable energy sources were studied throughout the semester to determine a feasible renewable energy plan for Calvin with a $5M investment.

2018 Fall Engr333 Project Final Report (Section A), 2018 Fall Engr333 Section A

ENGR 333

Calvin College currently spends 2.35 million dollars on energy every year. Physical Plant is under pressure to reduce the amount of energy that Calvin purchases from the electrical grid since the college is facing many budget constraints. In addition, President Le Roy signed the President’s Carbon Commitment to achieve carbon neutrality by 2057. With this need to save money on energy and reduce the college’s carbon footprint, the objective of this project was to determine the largest possible reduction in Calvin’s annual energy costs given a five-million-dollar investment in renewable energy.

Virtual Robot Climbing Using Reinforcement Learning, Ujjawal Garg

Master's Projects

Reinforcement Learning (RL) is a field of Artificial Intelligence that has gained a lot of attention in recent years. In this project, RL research was used to design and train an agent to climb and navigate through an environment with slopes. We compared and evaluated the performance of two state-of-the-art reinforcement learning algorithms for locomotion related tasks, Deep Deterministic Policy Gradients (DDPG) and Trust Region Policy Optimisation (TRPO). We observed that, on an average, training with TRPO was three times faster than DDPG, and also much more stable for the locomotion control tasks that we experimented. We conducted experiments and …

Chemistry & Biochemistry Faculty Works

Tuberculosis caused by Mycobacterium tuberculosis is currently one of the leading causes of death from an infectious agent. The main difficulties encountered in eradicating this bacteria are mainly related to (i) a very complex lipid composition of the bacillus cell wall, (ii) its ability to hide from the immune system inside the granulomas, and (iii) the increasing number of resistant strains. In this context, we were interested in the Rv0646c (lipGMTB) gene located upstream to the mmaA cluster which is described as being crucial for the production of cell wall components and required for the bacilli adaptation and survival in …

Deep Visual Recommendation System, Raksha Sunil

Master's Projects

Recommendation system is a filtering system that predicts ratings or preferences that a user might have. Recommendation system is an evolved form of our trivial information retrieval systems. In this paper, we present a technique to solve new item cold start problem. New item cold start problem occurs when a new item is added to a shopping website like Amazon.com. There is no metadata for this item, no ratings and no reviews because it’s a new item in the system. Absence of data results in no recommendation or bad recommendations. Our approach to solve new item cold start problem requires …
