Lung Ct Image Segmentation Using Vgg-16 Network With Image Enhancement Based On Bounded Turning Mittag-Leffler Function, Ali M. Hasan, Mohammed Khalaf, Bayan M. Sabbar, Rabha W. Ibrahim, Hamid A. Jalab, Farid Meziane

Baghdad Science Journal

Automated segmentation of diseases considered a necessary initial step in routine diagnosis. Lung diseases that affect the lungs, such as pneumonia or lung collapse can result in areas of consolidation or atelectasis, where lung tissue becomes denser or collapses. It can be challenging to accurately segment such areas, as they may exhibit similar characteristics to adjacent structures. This study proposes a lung CT image segmentation method which includes two steps: (1) a new image enhancement model that uses the bounded turning Mittag-Leffler function to improve the CT images for better segmentation outcomes. (2) a new modified VGG-16 for infection of …

Baghdad Science Journal

Drought stress is considered a limiting factor during the early growth stages of sorghum. An experiment was conducted under field conditions during the fall seasons of 2017 and 2018. The objective was to improve the growth of sorghum seedlings and their chemical properties to tolerate drought stress. Three variables were investigated: first factor cultivars (Inqath, Rabeh, and Buhoth70), second factor seed priming (primed and unprimed seed). Seeds were primed by soaking for 12 hours in a solution containing 300 mg L−1 + 70 mg L−1 of gibberellic (GA3) and salicylic (SA) acids, respectively, and third factor drought stress represented by …

Synthesis, Characterization And Antioxidant Study Of Some Metal Ion Complexes With Azo 1-(2,4,6-Trihydroxy-3-((3-Hydroxyphenyl) Diazenyl) Phenyl) Ethan-1-One., Areeg Malek Fadhel, Abbas Ali Salih Al Hamdani, Saad G. Mohamed

Baghdad Science Journal

During a diazotization coupling reaction, an azo dye-ligand (H4L) was formed by combining 3-aminophenol and 2,4,6-trihydroxyacetophenone. This ligand was then allowed to react with several different metal ions (Mo (VI), Fe (III), Co (II), Cr (III), Ru (III) and Rh (III)), forming stable metal complexes with various geometries. The binding of the azo-dye group to the metal ions was detected through the M-N and M-O absorption bands in Fourier-transform-infrared, which indicated the involvement of nitrogen and oxygen. LC-MS spectra confirmed the molecular weights of the ligand and its complexes, and elemental analysis was also conducted. Electronic spectra were used to …

Geoflood: Computational Model For Overland Flooding, Brian Kyanjo

Boise State University Theses and Dissertations

Overland flooding, a critical environmental phenomenon, poses significant challenges for computational modeling due to its complex hydrodynamics and the need for high-resolution data. This thesis presents GeoFlood, a new open-source software package for overland flooding simulations. The computational model solves shallow water equations (SWE) on a quadtree hierarchy of mapped, logically Cartesian grids managed by the parallel, adaptive library ForestClaw (Calhoun & Burstedde, 2017). The model is validated using standard benchmark tests from Neelz & Pender (2013) and against results from the GeoClaw software (George, 2011; Clawpack Development Team, 2020) for the historical Malpasset dam break problem. The benchmark test …

Plausibly Illiberal: Sua Sponte Dismissals Of Pro Se Complaints Under The Prison Litigation Reform Act, Pierce Edlich

Fordham Law Review

Over a quarter of civil litigants file suit in federal court without an attorney. Most unrepresented litigants are in prison, and many of their cases raise complex, delicate constitutional questions. The number of unrepresented litigants in federal courts rose steadily until the 1990s, when Congress passed the Prison Litigation Reform Act (PLRA) of 1995 to limit the burden of frivolous inmate litigation on federal courts. Since 1996, the PLRA has defined courts’ procedural obligations for inmate and in forma pauperis (IFP) suits, often filed pro se. The PLRA requires that courts screen and dismiss sua sponte cases that are frivolous, …

Nursing & Health Sciences Research Journal

Background: Heart failure is a complex clinical syndrome that requires the involvement of interdisciplinary teams to address patient needs and optimize therapy. Interdisciplinary teams, including physicians, advanced practice practitioners, and pharmacists, play a crucial role in implementing guideline-directed medical therapy and addressing barriers to self-care that ultimately improve patients’ overall survival. This study assessed the impact of an interdisciplinary team on patients’ heart failure outcomes compared to patients solely managed by clinical cardiologists. Methods: This was a single-center retrospective chart review study of Baptist Health patients seen at the heart failure clinic. The study compared patients seen by an interdisciplinary …

Influential Nature Of Empathy In The Relationship Between Psychopathy And Aggression, Alessia M. Valentino

Student Theses

Past research discusses the development of psychopathy and its association with aggression and empathy. It highlights that while personality traits central to psychopathy are believed to arise early in life, adolescence is a critical period where these traits interact and manifest in behaviors. Some research discusses the role of empathy in moderating aggressive behavior, suggesting that interventions targeting empathy could potentially reduce aggressive and antisocial behaviors in individuals with psychopathic traits. The current study explores the relationship between psychopathic traits, empathy, and aggression in adolescents, aiming to enhance our understanding of these complex constructs and their implications for risk assessment …
