A Game Theoretic Approach To Design Mating Programs For Livestock, Ebru Ergüneş Berki̇n, Hasan Önder, Özgür Hakan Aydoğmuş

Turkish Journal of Veterinary & Animal Sciences

In this study, we proposed a new game theoretic method to design a mating program. The index and game theoretic methods were applied with calculated breeding values using pedigree on two different data sets whose economic traits consist of negative (milk yield and fat percentage) and positive (birth and weaning weight) genetic correlated data. For the negative genetic correlated data set, even if total expected benefits were equal for two methods, mating programs were changed, and the coefficient of variation obtained using the game theoretic method was smaller than that of the index method. This result showed that the expected …

Productive Performance, Egg Quality, And Hatching Traits Of Japanese Quail Lines Selectedfor Higher Body Weight And Egg Number, Abdur Rehman, Jibran Hussain, Athar Mahmud, Khalid Javed, Abdul Ghayas, Sohail Ahmad

Turkish Journal of Veterinary & Animal Sciences

The present study evaluated the effect of selection for higher body weight (weight based selection = WBS) and egg numbers (egg based selection = EBS) on productivity, egg quality, and hatching traits of Japanese quail for three generations. From a base population of 1125 day-old chicks of Japanese quail, best performing families were allowed to propagate for getting next generation. WBS in G3 presented higher values of feed intake, egg weight, hatching weight. However, egg production and feed conversion ratio were better in EBS during G3. The incidence of embryonic mortality was also lower in the WBS line. In the …

Turkey's Transition To Face-To-Face Schooling During The Covid-19 Pandemic, Mahmut Özer, Hayri̇ Eren Suna, Matjaz Perc, Sadri̇ Şensoy, Sevi̇l Uygun İli̇khan

Turkish Journal of Medical Sciences

Background/aim: The COVID-19 pandemic majorly disrupted conventional schooling and many countries maintained educational services through distance education. The duration of school closures in Turkey was longer than most OECD countries, thus Turkey prioritized school reopenings in the 2021-2022 academic year to mitigate possible negative outcomes of closures. Here we study the compatibility of implications for school reopenings in Turkey with these practices and assess the first semester of face-to-face schooling. Materials and methods: We have used document analysis to present and compare the practices in Turkey with international practices. We also used a comparative approach to assess the coherence between …

Insect breeding or farming for food and feed is an emerging enterprise that can address the ever-growing demand for protein and curb high unemployment rates in Africa and beyond. However, for the sector to prosper, its value chain needs to be regulated to ensure sustainability and safety for consumers and the environment. Although a few African countries, such as Kenya, Uganda and Rwanda, have promulgated standards on the use of insects as food and feed, greater efforts are needed in other countries, and relevant policies governing the sector need to be formulated. All over the globe, attention to the regulation …

Let The Machines Do The Dirty Work: Social Media, Machine Learning Technology And The Iteration Of Racialized Surveillance, Subhah Wadhawan

Canadian Journal of Law and Technology

Post 9/11, where the current social and cultural temperature has constructed Islam as interchangeable with terrorism, digital intermediaries have responded with increased censorship of speech related to, emerging from, or advocating Islamic ideology. At the heart of this paper is the argument that digital intermediaries have relied on the opaqueness of machine learning technology (‘‘MLT”) to realize racialized surveillance, whereby speech concerning Islamic content has been disproportionally censored. This paper maps out how inherent biases concerning the ideology of Islam have been interwoven into the coding and machine learning used by the major tech giants. As a result of the …

Using Multiple Environmental Tracers To Estimate Field-Scale Longitudinal Dispersivity, Casey L. Kleppel

Graduate Student Theses, Dissertations, & Professional Papers

In this study, we seek to reduce parameter uncertainty in groundwater modeling systems, particularly in reactive transport models, by quantifying effective field-scale longitudinal dispersivity using anthropogenic environmental tracers. We generate synthetic aquifer fields and model transport of atmospheric tracers and test whether tracers can be used to determine an effective aquifer-scale dispersion coefficient. We generate synthetic datasets by simulating transport of chlorofluorocarbons (CFC11, CFC12, CFC113), sulfur-hexafluoride (SF₆) and tritium (³H) with input functions derived from known atmospheric concentrations, through a three-dimensional, stochastic, heterogeneous synthetic aquifer developed using sequential Gaussian simulation using the PFLOTRAN reactive transport model. …

Boron Isotopes In Boninites Document Rapid Changes In Slab Inputs During Subduction Initiation, Hong-Yan Li, Xiang Li, Jeffrey G. Ryan, Chao Zhang, Yi-Gang Xu

School of Geosciences Faculty and Staff Publications

How subduction-related magmatism starts at convergent plate margins is still poorly understood. Here we show that boron isotope variations in early-formed boninites from the Izu-Bonin arc, combined with radiogenic isotopes and elemental ratios document rapid (~0.5 to 1 Myr) changes in the sources and makeup of slab inputs as subduction begins. Heterogeneous hornblende-granulite facies melts from ocean crust gabbros ± basalts fluxed early melting to generate low silica boninites. Hydrous fluids from slab sediments and basalts later fluxed the low silica boninites mantle source to produce high silica boninites. Our results suggest that initially the uppermost parts of the slab …

The Legacy Of Hurricanes, Historic Land Cover, And Municipal Ordinances On Urban Tree Canopy In Florida (United States), Allyson B. Salisbury, Andrew K. Koeser, Richard J. Hauer, Deborah R. Hilbert, Amr H. Abd-Elrahman, Michael G. Andreu, Katie Britt, Shawn Landry, Mary G. Lusk, Jason W. Miesbauer, Hunter Thorn

School of Geosciences Faculty and Staff Publications

Urban Tree Canopy (UTC) greatly enhances the livability of cities by reducing urban heat buildup, mitigating stormwater runoff, and filtering airborne particulates, among other ecological services. These benefits, combined with the relative ease of measuring tree cover from aerial imagery, have led many cities to adopt management strategies based on UTC goals. In this study, we conducted canopy analyses for 300 cities in Florida to assess the impacts of development practices, urban forest ordinances, and hurricanes on tree cover. Within the cities sampled, UTC ranged from 5.9 to 68.7% with a median canopy coverage of 32.3% Our results indicate that …

Modeling Through, Ryan Calo

Articles

Theorists of justice have long imagined a decision-maker capable of acting wisely in every circumstance. Policymakers seldom live up to this ideal. They face well-understood limits, including an inability to anticipate the societal impacts of state intervention along a range of dimensions and values. Policymakers cannot see around corners or address societal problems at their roots. When it comes to regulation and policy-setting, policymakers are often forced, in the memorable words of political economist Charles Lindblom, to “muddle through” as best they can.

Powerful new affordances, from supercomputing to artificial intelligence, have arisen in the decades since Lindblom’s 1959 article …

School of Geosciences Faculty and Staff Publications

The Lazufre Volcanic System (LVS), on the border of northern Chile and Argentina, is an active complex of two volcanoes, Lastarria to the north and Cordón del Azufre to the south. The LVS is not regularly monitored with any scientific equipment despite being recognized as a top ten volcanic hazard in Argentina by the Observatorio Argentino de Vigilancia Volcánica of the Servicio Geológico y Minero Argentino. The system has shown unusual inflation signatures observed in InSAR but the level of seismic activity and its spatial and temporal distribution were unknown due to the lack of a permanent local seismic network. …

Scientific Breakdown Of A Ferromagnetic Nanofluid In Hemodynamics: Enhanced Therapeutic Approach, M. M. Bhatti, Sara Abdelsalam

Basic Science Engineering

In this article, we examine the mechanism of cobalt and tantalum nanoparticles through a hybrid fluid model. The nanofluid is propagating through an anisotropically tapered artery with three different configurations; converging, diverging and non-tapered. To examine the rheology of the blood we have incorporated a Williamson fluid model which reveals both Newtonian and non-Newtonian effects. Mathematical and physical formulations are derived using the Lubrication approach for continuity, momentum and energy equations. The impact of magnetic field, porosity and viscous dissipation are also taken into the proposed formulation. A perturbation approach is used to determine the solutions of the formulated nonlinear …

On Behavioral Response Of Ciliated Cervical Canal On The Development Of Electroosmotic Forces In Spermatic Fluid, Sara I. Abdelsalam, A. Z. Zaher

Basic Science Engineering

The goal of this research is to conduct a theoretical investigation about the effect of the electroosmotic forces on the swimming of sperms throughout the cervical canal. To imitate male semen with self-propulsive spermatozoa, a hyperbolic tangent fluid is used as the base liquid. Swimming sperms move inside a ciliated cervical canal and peristalsis occurs due to the ciliated walls. The perturbation method is used to solve the controlling partial differential set of equations analytically. Due to selfpropulsion of swimmers and long wavelength assumption, a creeping flow protocol is used throughout the stream. The stream pattern, velocity distribution, and pressure …

Computational Framework Of Magnetized Mgo–Ni/Water-Based Stagnation Nanoflow Past An Elastic Stretching Surface: Application In Solar Energy Coatings, M, M. Bhatti, O. A. Bég, Sara Abdelsalam

Basic Science Engineering

In this article, motivated by novel nanofluid solar energy coating systems, a mathematical model of hybrid magnesium oxide (MgO) and nickel (Ni) nanofluid magnetohydrodynamic (MHD) stagnation point flow impinging on a porous elastic stretching surface in a porous medium is developed. The hybrid nanofluid is electrically conducted, and a magnetic Reynolds number is sufficiently large enough to invoke an induced magnetic field. A Darcy model is adopted for the isotropic, homogenous porous medium. The boundary conditions account for the impacts of the velocity slip and thermal slip. Heat generation (source)/absorption (sink) and also viscous dissipation effects are included. The mathematical …

Regulatory Constitutional Law: Protecting Immigrant Free Speech Without Relying On The First Amendment, Michael Kagan

Georgia Law Review

The Supreme Court has long deprived immigrants of the full protection of substantive constitutional rights, including the right to free speech, leaving undocumented immigrants exposed to detention and deportation if they earn the government’s ire through political speech. The best remedy for this would be for the Supreme Court to reconsider its approach. This Essay offers an interim alternative borrowed from an analogous problem that arises under the Fourth Amendment. Under the Constitution, the Supreme Court has indicated that illegally obtained evidence may be suppressed in a removal proceeding only if the Fourth Amendment violation was “egregious.” Yet, some circuit …

Economics Of Markets: Neoclassical Theory, Experiments, And Theory Of Classical Price Discovery, Sabiou M. Inoua, Vernon L. Smith

ESI Publications

This book establishes that neoclassical economics based on the marginal utility calculus failed to derive a theory of consumer market price discovery consistent with the experimental market evidence. Such markets involve inherently discrete final-demand items bought for consumption and not subject to resale. Classical economists following Adam Smith articulated a rich narrative of price discovery theory consistent with experimental evidence based on operational concepts of discrete demand values (maximum willingness-to-pay), and symmetrically, supply costs (minimum willingness-to-accept). We develop and extend a mathematical model of classical market price formation. Chapter 1 & 2 describes this theme and chapter 3 connects it …
