Technical science and innovation

Reliable assessment of wind energy potential in regions characterized by complex terrain is often constrained by the limited availability of ground-based meteorological measurements. This study proposes an improved regression-based approach for refining wind speed estimates at the wind turbine hub height of 65 m using satellite-derived data from the NASA POWER database combined with a logarithmic vertical wind profile. The proposed methodology is validated using real operational data from a 750 kW wind power plant located in the mountainous Bostanlyk district of Uzbekistan for the period 2018–2021. The regression analysis demonstrates a strong linear relationship between the extrapolated wind speed …

Design Of Virtual Impedance Controller For Parallel-Connected Converters In A Microgrid, Manyanda Makoye, Francis Mwasilu, Peter M. Makolo, Jackson Justo

Tanzania Journal of Science

This paper addresses the significant challenge of inaccurate power sharing among Distributed Generators (DGs) in islanded microgrids, which is primarily caused by mismatched feeder and line impedances. Conventional decentralized control solutions often fail to ensure accurate power sharing, especially when line impedances are resistive. To overcome this, the paper proposes a robust, coordinated Virtual Impedance Control (VIC) strategy for DGs. This method implements fixed virtual resistance and virtual inductance to standardize the output impedance characteristics of parallel-connected inverters, thereby minimizing impedance discrepancies and enhancing system stability through increased damping. The theoretical analysis and design of the VIC were validated through …

The Military Officer's Oath To Disobey Lawful But Unethical Orders, Joshua Braver

Northwestern University Law Review

How should a military officer respond to a lawful yet unethical order, unethical in the sense that it conflicts with their professional responsibilities? Army culture, scholarship, and doctrine regard officers as professionals, akin to doctors and lawyers, with expertise in the management of violence and a shared commitment to an ethical code. This code demands obedience to lawful orders to uphold civilian control of the military. But to protect against civilian misuse of the military, the code requires disobedience to unethical orders. Faced with a lawful but unethical order, the military officer is mired in a contradiction in which their …

What The Free-Roaming Cats Dragged In: Regulatory Concerns With Privatized Local Services, Jonathan Korger

Northwestern University Law Review

The United States entrusts local governments to provide citizens with a wide range of public services, and animal control makes up a small but essential piece of these local responsibilities. In recent years, American localities have largely privatized how they manage the nation’s growing free-roaming cat population, relying primarily on animal-loving volunteers and a controversial practice called trap-neuter-return (TNR). Academics have long debated the merits of privatization, but TNR raises a novel question: how should local governments think about regulating a privatized public service when altruism, instead of profits, motivates the service deliverer? This Note argues that TNR demonstrates the …

A Tale Of Two Credits: The Post-Nestlé Alien Tort Statute And Carbon Credit Externalities, Stephanie Mao

Northwestern University Law Review

As companies increasingly embrace carbon-neutrality commitments, many rely on the voluntary carbon market to offset their emissions rather than reduce them directly. Regulatory and consumer scrutiny has focused on the widespread use of “phantom” carbon credits, i.e., credits that fail to produce meaningful climate benefits. But less attention has been paid to what this Note terms “colonial” carbon credits: those that may technically reduce emissions but do so at the expense of communities abroad. These projects may contribute to land dispossession, human rights abuses, and threats to public and environmental health. Yet, current regulatory and legal frameworks, with their focus …

Should Judicial Opinions Be Read Like Statutes?, Margaret H. Lemos

Northwestern University Law Review

Should judicial opinions be interpreted with an eye to their purpose, context, or the intent of their authors, or should interpreters focus on the ordinary meaning of the text? Opinions present the same sorts of interpretive puzzles as other legal texts, and yet they have been omitted from the debates over interpretive methodology that dominate the fields of constitutional and statutory interpretation. The omission is no accident: the Supreme Court has stated repeatedly—and with increasing frequency in recent years—that judicial opinions are not to be read like statutes. Yet neither courts nor commentators have explained why the principles that ground …

The Ex Parte Young Cause Of Action: A Riddle, Wrapped In A Mystery, Inside An Enigma, Andrew S. Oldham, Adam I. Steene, John W. Tienken

Northwestern University Law Review

Ex parte Young ushered in a new era of the American judicial system. Most famously, the decision allowed plaintiffs, in certain circumstances, to sue state officials without having to worry about sovereign immunity. Young’s other holding, though perhaps lesser known, is no less important: individuals, the Supreme Court held, have an equitable cause of action to sue government officials for injunctive relief.

Even today, that second holding remains something of a riddle. Did this cause of action always exist in American law? Or was it an invention of the Young Court? And, at any rate, does the Ex parte …

Place Names And Presidential Control, Austin Kruse

Northwestern University Law Review

Since the start of his second term, President Trump has issued executive orders at an extraordinary pace, using them to advance a broader ideological agenda across the administrative state. While scholarly attention has largely focused on the most sweeping of these directives, less prominent orders raise similar concerns about the reach of presidential power. This Note examines one such order: Executive Order 14,172, which directs the renaming of the Gulf of Mexico and Denali and expands presidential influence over the U.S. Board on Geographic Names (BGN).

Although geographic naming is ostensibly apolitical, place names are deeply entangled with questions of …

Pre-Experiential Constraint Reconstruction: A Structural Account Of The Prior Layer In Dialogue With Jung, Griselda Poe

Publications and Research

Experiences commonly described as pre-experiential memory—such as immediate recognition, familiarity without prior exposure, and the sense of "already knowing"—are typically interpreted as the retrieval of stored content. However, this storage-based account does not provide a structurally consistent explanation of how such content is preserved prior to experience or reactivated in a form that aligns with present input.

This paper extends the three-layer cognitive architecture developed in prior work in this series (Poe, 2026n), in which cognition operates across Core processing, Modulation, and an operationally inaccessible Prior layer that supplies constraints to all processing.

This paper proposes an alternative account in …

Dual History Enhancement With Hybrid Hypergraph-Graph Networks For Temporal Knowledge Graph Reasoning, Kailun Ye, Xiangjie Kong, Yuchao Zhang, Xuan Wang, Linan Zhu, Jiaxin Du, Guojiang Shen, Jianxin Li

Research outputs 2022 to 2026

Temporal Knowledge Graph (TKG) reasoning seeks to predict future events by analyzing historical data, where the effective leverage of both local and global historical facts proves crucial. Existing approaches employ graph neural networks (GNNs) and recurrent neural networks (RNNs) for local evolution patterns, complemented by statistical methods to enhance attention to global facts, demonstrating efficient predictive capabilities. However, traditional GNNs, constrained by their low-order neighborhood aggregation design, inherently fail to model potential high-order dependencies among facts. Furthermore, existing global history modeling approaches may introduce irrelevant historical information that interferes with prediction tasks. To address these limitations, we propose a Dual …
