Moving Towards Wellness: How Exercise Can Ease Depression And Anxiety In Young Adults, Morgan Hartze

Psychology Student Publications

Depression and anxiety are among the most common mental health concerns affecting young adults, impacting mood, motivation, and daily functioning. While therapy and medication can be effective, many young adults continue to experience symptoms, highlighting the need for additional strategies. Research suggests that regular physical activity is an accessible, cost-effective way to improve mental health. Moving your body boosts the “feel good” chemicals, such as serotonin and dopamine, while reducing stress hormones, such as cortisol. Physical activity also provides a healthy distraction from negative thoughts and helps establish routines that support well-being. Even brief amounts of moderate exercise, such as …

Couples Neutrality, Marriage Neutrality, And Two-Earner Deductions, Daniel Shaviro

Loyola of Los Angeles Law Review

Tax policy discussions of how to tax married couples, as compared to singles, often focus on the by now much-criticized norms of “marriage neutrality” and “couples neutrality.” While these norms are largely unpersuasive, they do offer a useful analytic starting point, because of both (a) how they relate to more validly expressed concerns, and (b) the significance of the empirical reasons why they generally do not hold.

In evaluating the proper relative tax treatment of different married couples, one of the most important factors that the federal income tax law fails to recognize is the difference between one-earner and two-earner …

Motive To Kill: The Link Between Childhood Trauma And Homicide, Natalie L. Scholz

Psychology Student Publications

What motivates some individuals to commit homicide and what role does childhood trauma play in increasing that risk? Psychology and neuroscience suggest that when a child experiences traumatic events it can change how they handle stress, emotional control, and how their brain develops. All these factors can lead to them acting out in more violent ways. The Adverse Childhood Experiences study shows that traumatic events during one’s childhood can have a negative effect on their mental wellbeing later in life making them more prone to act out aggressively and possibly having more criminal involvement. Exposure to trauma has been linked …

The Science Of Attachment: How Early Bonds Shape Who We Become, Rani Patel

Psychology Student Publications

Attachments theories suggest the answer begins in infancy. Originally developed by John Bowlby and later supported by the “Strange Situation” attachment research conducted by Mary Ainsworth, attachment science shows that the quality of early interactions with caregivers influence how children develop trust, seek support, and manage emotions. Through years of empirical research psychologists have identified four main attachment styles, secure, anxious, avoidant, and disorganized, later connected to relationship patterns. Modern research also highlights that attachment patterns are not permanent, supportive experiences later in life can promote growth and change.

Experiential Avoidance And Acceptance-Based Therapy (Abbt), Addison Jo Quern

Psychology Student Publications

Anxiety is an incredibly common mental health concern that impacts individuals globally. Avoidance is a main feature that maintains the symptoms of anxiety but does not allow the individual to experience the distressing scenario, thus reaffirming that discomfort. This attempt to control or avoid anxiety can make the symptoms worse. Research demonstrates that avoidance can perpetuate anxiety, and stress can increase avoidance. Acceptance-based therapy (ABBT) is used to target avoidance behaviors to lessen the overall symptoms of anxiety. ABBT is a third wave of therapy that helps clients focus on the relationship they have with their thoughts and feelings, instead …

The right internal mammary artery (RIMA) is commonly employed as a second conduit; however, it is unclear whether the free (fRIMA) or in situ (isRIMA) configuration yields superior outcomes. We performed a systematic review and meta-analysis to compare clinical outcomes between fRIMA and isRIMA as the second conduit.

METHODS: A comprehensive search of PubMed (MEDLINE), EMBASE, and CENTRAL was performed through May 2025 to identify studies comparing outcomes in patients undergoing coronary artery bypass grafting with either fRIMA or isRIMA as a second …

Optimal Control And Bifurcation Analysis Of A Predator–Prey Model With Self-Limiting Growth And Predator Disease, Dipo Aldila, Muhammad Akmal Fasya, Bevina D. Handari, Chidozie Williams Chukwu, Olumuyiwa James Peter

Mathematical Modelling and Numerical Simulation with Applications

We propose and analyze an eco-epidemiological predator–prey model that incorporates self-limitation and disease transmission within the predator population. The model is formulated as a system of ordinary differential equations describing logistic prey growth under the interspecific interaction with the predator. On the other hand, the predator population is divided into susceptible and infected classes, whose growth is constrained by prey availability. Three biologically relevant equilibria are identified: predator extinction, disease-free coexistence, and coexistence with endemic disease. The existence and stability of these equilibria are determined by key ecological and epidemiological thresholds, including the basic reproduction number. Using numerical continuation methods, …

Employing Effective Solution Methods For Caputo-Based Sequential Fractional Models, Eman A. A. Ziada, Mohamed F. Abouelenein, Hijaz Ahmad, Monica Botros

Mathematical Modelling and Numerical Simulation with Applications

This paper investigates a class of nonlinear sequential singular fractional differential equations (FDEs) involving Caputo derivatives. This type of equation has several key advantages that enhance its value, such as capturing memory and hereditary effects. Viscoelastic materials and anomalous diffusion, as well as biological systems, can take advantage of this feature. In addition, fractional derivatives possess a sequential structure that enables the implementation of multiscale processes and hierarchical memory responses. Moreover, it provides an effective and flexible framework for solving differential equations compared to classical differential equations. It can therefore be used to model complex systems in physics, biology, and …

Using a nonlinear least-squares approach, model parameters and fractional order are estimated using epidemiological data from the World Health Organization. The basic reproduction number $R_0 = 0.53$ indicates that the disease is under control after adding …

Exact Soliton Solutions Of The Nonlinear Time-Fractional Schrödinger Equation Via Atangana–Baleanu And M-Truncated Operators, Bahadır Kopçasiz, Fatma Nur Kaya Sağlam, Mehmet Şenol

Mathematical Modelling and Numerical Simulation with Applications

The main objective of this work is to obtain exact soliton solutions for a nonlinear time-fractional equation model describing wave profiles arising in various physical systems. To derive different wave structures associated with the considered model, two analytical techniques are employed: the extended G'\G^2-expansion method and the modified auxiliary equation (MAE) approach. A wave transformation is applied to reduce the nonlinear time-fractional equation to a nonlinear ordinary differential equation (NLODE) by means of the M-truncated and Atangana-Baleanu (AB) fractional operators. Several classes of solutions, including exponential, hyperbolic, and trigonometric wave forms, are obtained. Over and above the analytical results, graphical …

Dynamical Analysis And Optimal Control Of The Mpox Transmission Model With Stratified Susceptibility, Tuhfatul Janan, Fatmawati Fatmawati, Cicik Alfiniyah, Santi Martini, Dipo Aldila, Agus Hasan

Mathematical Modelling and Numerical Simulation with Applications

This study develops a mathematical model of Mpox transmission that combines stratified susceptibility (low-risk and high-risk groups) with vaccinated and asymptomatically infected compartments. The analysis of the model begins with examining the well-posedness, boundedness, and nonnegativity conditions for the solutions. The local stabilities of the equilibria are examined through the Jacobian matrix and phase plane analysis, while the global stabilities are provided through Lyapunov functions. The estimated parameters are verified using epidemiological data on Mpox cases in the United States, with an MAPE of 2.20% and R_0 > 1, indicating that Mpox remains endemic. Sensitivity analysis indicates that the contact rate …

Emergent Operator Logic: A Foundational Framework For Dynamic Reasoning And Generative Intelligence, Mona Gharib, Abduallah Gamal, Muhammad Nawaz, Basma Nasir

Neutrosophic Systems with Applications

This paper introduces Emergent Operator Logic (EOL), a framework that treats propositions as continuous operators $F_p:X \rightarrow X$ on a complete metric state space $( X,d )$ and evaluates truth after action via a continuous valuation $V:X \rightarrow [ 0,1 ]$. Logical composition is realized by three operator-level connectives: sequential $p \circ q$(causal order), parallel $p\parallel q$(1-Lipschitz cooperative blend), and the emergent synthesis $E( p,q ) = \frac12( F_p \circ F_q + F_q \circ F_p )$, which symmetrizes non-commuting actions. We provide a Hilbert-style proof system (sound), an algebraic semantics via E-algebras, and show that the category of E-algebras is …

Regulation Of Zygotic Genome Activation By The Nucleocytoplasmic Ratio, Lily Acker, Hui Chen

Faculty Publications

During early development, embryos undergo the maternal-to-zygotic transition (MZT), when control of development shifts from maternal factors to the newly activated zygotic genome. Decades of studies in various model organisms suggest that the nucleocytoplasmic (N/C) ratio is a key regulator of zygotic genome activation (ZGA), though this relationship is more nuanced in some organisms than others. Changing the nuclear content, nucleus size or cell size has been shown to shift the timing of ZGA. Mechanistically, the N/C ratio is linked to fundamental cellular processes that regulate genome activities, including nuclear import, repressor titration, activator accumulation, cell cycle lengthening, and chromatin …

Chronic Post-Mastectomy Pain: Insights Into Mechanisms, Prevention, And Treatment Approaches, Abdulaziz H. Algain

Journal of Medical Rehabilitation Science

Chronic post-mastectomy pain (CPMP) is a prevalent and significant concern for many breast cancer surgery patients, affecting between 25% and 60% of females within the first year after surgery. This multifactorial condition arises from a combination of peripheral nerve injury, central sensitization, and immune-mediated inflammation. Although no single intervention can fully prevent CPMP, a comprehensive, multidisciplinary approach that addresses the biological, psychological, and social aspects of pain is crucial for enhancing the quality of life for breast cancer survivors. It is often underrecognized by clinicians, who may attribute pain to the expected postoperative recovery process, while patients sometimes accept discomfort …

Defining The Palette Of Biodeterrence: Appreciating A Broader Toolkit, Diane Dieuliis, James Giordano

Strategic Insights

Biological threats present unique challenges to traditional deterrence models due to their dual-use nature, difficulties in attribution, and rapidly evolving scientific landscape. In this commentary, the authors argue that deterrence by denial, while essential, is insufficient on its own to address contemporary biothreats. They propose a broader framework that integrates deterrence by disruption and capability diminishment to interfere with and reduce adversaries’ ability to develop and employ biological weapons. This approach emphasizes coordinated efforts across scientific, technological, economic, intelligence, and policy domains, as well as collaboration with public health and international partners. By shaping the conditions under which biological weapons …
