Zymal Tahir Introduction: One of the most vital emotion that is a part of a human emotion spectrum is fear. At face value, it is an emotion felt by everyone on a day-to-day basis when one see or feel something around that may harm them. Diving deeper into it psychologists tend to define fear as a defensive primitive emotion that triggers a biochemical and emotional response, urging us to keep a distance from the danger around us. At times the fear we feel might become unproportionate to the danger causing it. When experiences of intense fear towards a certain danger, object, or living organism consistently start becoming unproportionate, it is termed as a Phobia . According to an Article by MedicalNewsToday Phobias are defined as “ A phobia is a type of anxiety disorder that causes an individual to experience extreme, irrational fear about a situation, living creature, place, or object.”   The purpose of this research paper is to understand the phenomena of phobias in-depth, such a...

  Application of Feature Engineering for Breast Cancer Tumor Detection Ashley Chang Abstract Breast Cancer is the most prevalent cancer, being one of the top five causes of mortality. During breast cancer screenings, it is important for doctors to determine whether a tumor is benign (non-cancerous) or malignant (cancerous) in order to determine the patient's prognosis and course of treatment. However, inconsistent interpretation of ultrasound images by doctors can result in incorrect diagnoses and treatments, affecting patient care and outcomes. Thus, in this study, a machine learning model was built using convolutional neural networks (CNN) to help with the diagnosis and classification of breast cancer tumors. A dataset containing 800 images separated into normal, benign, and malignant breast cancer ultrasounds was acquired and uploaded into Jupyter Notebook. Custom data augmentation techniques were applied to the images to increase data variation. Regularization techni...

  A research paper by Syeda Fatima Hussain Introduction Migration, which in this study we might refer to as ‘gene flow’ [ 1 ] , has played a crucial role in determining the diversity and evolution of humans. Through reproduction, migration introduces new genes and alleles into populations, which in turn affects genetic diversity. The genetic landscape of human and other populations has been modified by this process. [ 2 ] This study examines the connection between migration and these evolutionary processes, emphasizing the need of genetic research in determining humankind's common ancestry and history.  Thanks to developments in the field of genetic science, it is now possible to precisely manipulate genetic material to create a molecular record of past migrations and population expansions. This presents previously unheard-of prospects for further evolutionary investigations, by virtue of tools like Next Generation Sequencing (NGS) [ 3 ] . Through this, scientists are able to...
