Coupled-Pendulum Modeling In An Ode Class: An Assignment On Fourier-Initialized Gradient Descent In Machine Learning, Huy Truong, Andrew Bennett

CODEE Journal

As data-driven methods are increasingly used in science and engineering, students benefit from learning to integrate machine learning techniques with traditional mathematical modeling. We present a hands-on extra-credit assignment for an undergraduate ordinary differential equations (ODE) course that enables students to compare classical analytical methods with data-driven approaches on the same physical system. Using a coupled-pendulum system---two pendulums connected by a spring---with real experimental data acquired via video tracking of a real physical setup, students work through three models in a guided Jupyter notebook with all code provided. First, they fit a neural network with Fourier features as a purely …

Efficient Dynamic Mechanism Design Without A Common Prior, Dirk Bergemann, Marek Bojko

Cowles Foundation Discussion Papers

We study efficient dynamic mechanism design with independent private values when agents do not share a common prior over the stochastic environment. Each agent privately observes the stochastic kernel governing the evolution of her own type and may hold arbitrary beliefs about the kernels of others. We extend the agents’ type space to include the kernel itself and show that the dynamic team mechanism of Athey and Segal (2013) and the dynamic pivot mechanism of Bergemann and Välimäki (2010) implement the socially efficient allocation in periodic ex-post equilibrium. We further show that kernels can be elicited only once, at the …

The Creation Of Immovable Real Rights By Testament In Kosovo: A Comparative Approach, Bedri Bahtiri, Kastriote Vlahna

Journal of Civil Law Studies

The establishment of real rights over immovable property constitutes a central issue in contemporary civil law. This paper investigates whether a testament (testamentum) may function not merely as an instrument for the mortis causa transfer of existing real rights but also as a juridical title (titulus iuris) capable of constituting new real rights (constitutio iuris). The analysis emphasizes the doctrinal distinction between the transfer of ownership (translatio dominii) and the creation of rights (constitutio iuris) within the legal framework of Kosovo, further examined through a comparative lens with the German Bürgerliches Gesetzbuch (BGB) and the French Code Civil.
Drawing on …

Collaboration, Coopération Et Intérêt Commun : La Fluidité De L’Exigence De Bonne Foi En Droit Égyptien Et Français Des Contrats, Rana Mohammad Safi

Journal of Civil Law Studies

Le contrat, étant la source d’obligation primordiale dans la société, a connu une évolution remarquable depuis le XIXe siècle. Créant des obligations réciproques, le contrat peut être perçu sous un prisme antagoniste, chaque contractant veillant à ses propres intérêts avant les intérêts du cocontractant. Cependant, le droit des obligations connut une émergence des devoirs contractuels, notamment avec l’introduction de la bonne foi, renforcée au cours du temps pour inclure, en plus de l’honnêteté, les devoirs d’information, de loyauté et de coopération. Certains ont même considéré que cette évolution a conduit à une « crise du contrat » affaiblissant le fondement …

Aberrant Ciliogenesis Induced By Enhanced Bmp Signaling Causes Heterotopic Ossification, Hiroyuki Yamaguchi, Jianbo Wang, Fangfang Yan, Jiarui Bi, Radbod Darabi, William R. Lagor, Zhongming Zhao, Aris N. Economides, Yuji Mishina, Yoshihiro Komatsu

Faculty, Staff and Student Publications

Bone morphogenetic protein (BMP) signaling is a principal driver of heterotopic ossification (HO), yet how aberrant BMP activity structurally reprograms cellular signaling machinery to develop HO remains unclear. Here, we identify BMP signaling as a direct upstream regulator of ciliogenesis that coordinates a multi-stage, pro-osteochondrogenic signaling relay during HO. Using a conditional gain-of-function BMP mouse model (Acvr1Q207D/+), we demonstrate that enhanced BMP signaling promotes primary cilium biogenesis and axonemal elongation through canonical Smad1/5/9-dependent transcriptional activation of intraflagellar transport (IFT) Ift20, a core component of the IFT machinery. Rather than operating via a singular downstream cascade, these elongated …

Revisiting The Genesis Of French Louisiana: It’S No Coincidence The Civil Code Was Adopted—We Ain’T Anglos!, Warren Perrin

Journal of Civil Law Studies

This article examines how Louisiana’s distinctive civil law tradition survived the Louisiana Purchase and became embedded in the state’s identity through the interaction of culture, migration, and political compromise. Tracing the development of French Louisiana from the Acadian diaspora to statehood, the article argues that the adoption and preservation of the civil code was not accidental, but rather the product of a deeply rooted Francophone and multicultural society resistant to Anglo-American common law traditions. The study highlights the influence of major historical figures including Thomas Jefferson, William C.C. Claiborne, Julien Poydras, Casa Calvo, and Edward Livingston, while also emphasizing the …

La Place De La Loi Dans Le Code Civil De 1804 : Regard Rétrospectif, Mustapha Mekki

Journal of Civil Law Studies

La loi était conçue en 1804 comme le modèle normatif. Elle était la reine des sources et remplissait une noble fonction pédagogique et morale. Ce constat pouvait être fait également du code civil louisianais. Avec le temps, la concurrence entre les sources, le pluralisme juridique, la globalisation, le dogme de l’efficacité, ont-ils eu raison de cette fonction modèle attribuée à la loi au début du 19e siècle ? Cette étude s’efforce d’exposer cette loi mise à l’épreuve et de présenter ce qu’il reste de ce modèle normatif dans notre paysage juridique.

Civil Code Reforms And Sources Of Law: The French And Quebec Experience Compared, Pascale Deumier, Mathieu Devinat

Journal of Civil Law Studies

Can civil codes be reformed “like any other piece of legislation?” A comparison of the French and Quebec experiences illustrates the methodological challenges that arose from civil code reform projects for the Civil Code of Québec during the last two Centuries. It also reveals the complex relationship that jurists have with “their” own civil code, in a civil law context.

The Civil Law English Terminology (Civlet), A Louisiana Gift To The World, Olivier Moreteau

Journal of Civil Law Studies

In the early 19th century, Louisiana codified its civil law in French and in English. In the 20th century, it translated French civilian doctrine and then produced its own civilian literature in English. Over time, lawmakers and translators have crafted and refined new English legal terminology suited to expressing civilian concepts, thereby setting aside common law terminology. Quebec joined the process once Canada imposed bilingualism, while other English-speaking mixed jurisdictions also contributed. This article shows how, outside the common law English terminology (COMLET), a civil law English terminology (CIVLET) is developing, and is also enriched by a comparative law English …

Immuno-Endocrine And Inflammatory Modifications In Human Toxoplasmosis: Diagnostic And Predictive Value Of Progesterone And Prostaglandin, Murtadha Hadi Ajmi

Muthanna Medical Journal

Toxoplasma gondii is one of the world's most common parasitic infections, with well-known effects on the immune system but poorly understood effects on the endocrine system and inflammation. Emerging literature indicates that the parasite alters the hormonal balance of the host, which may play a role in the development of disease, inflammation and poor health outcomes. But the diagnostic and predictive value of these immuno-endocrine changes in human toxoplasmosis remains poorly understood. In this case-control study, 45 patients with toxoplasmosis and 28 healthy controls were enrolled. White blood cell count, packed cell volume, erythrocyte sedimentation rate, progesterone and prostaglandin were …
