Study On Calculation Method For Incremental Launching Based On Nonlinear Analysis, Mo Shanfeng, Huang Cailiang, Qin Hui

Journal of China & Foreign Highway

In view of the shortcomings of traditional incremental launching calculation methods and the assembly construction control of incremental launching beams, an incremental launching calculation method based on nonlinear analysis was proposed in this paper. This method could truly simulate the running state where the incremental launching pier remains stationary, and the beam moves forward. The assembly alignment of all segments of the beam and the real alignment of the beam under specified working conditions could be directly output. The prefabricated alignment of the main beam (i.e., unstressed alignment) did not need to be consistent with the slide alignment. When the …

From Pathology To Ecology: Rethinking Student Well-Being Through Consciousness-Centered Education, Molly Beauregard

Journal of Conscious Evolution

This article revisits a five-year mixed-methods study conducted from 2012 to 2018, involving 207 student participants (n = 207), of an undergraduate sociology course—Consciousness, Creativity, and Identity—that integrated group meditation and mindfulness into a standard curriculum. Earlier analyses interpreted positive outcomes primarily as reductions in stress and improvements in attention among students. This paper reconsiders that interpretation, arguing that such a framing risks locating dysfunction within students rather than the social and cultural environments they inhabit.

Drawing on an ecological perspective, the study reexamines survey, reflection, and interview data documenting changes, not only in affect and attention, …

Walking The Tightrope: The Precautionary Dilemma Of Neutrality And Guidance, Farhan Lakhany

Animal Sentience

Jonathan Birch’s The Edge of Sentience promises a precautionary framework that guides ethical action without taking sides in the disputed metaphysics of consciousness. I argue that it cannot do both. Birch admits “biopsychism” (that all living organisms are conscious) into his "zone of reasonable disagreement," yet his operational criteria exclude plants and unicellular organisms by requiring evidence that biopsychism holds to be irrelevant. This leaves a dilemma. Keeping the “broad” standard preserves neutrality but extends candidacy to all life, guiding nothing; restricting to scientific evidence guides action but is itself the theoretical commitment the framework was meant to avoid.

A Communication-Aware Game-Theoretic Coordination Framework For Distributed Pump Stations In Pipeline Systems, David A. Brattley, Wayne W. Weaver

Michigan Tech Publications

In large-scale fluid transport systems, distributed pump and valve stations must coordinate their operations to prevent overpressure while minimizing energy use and control effort. This paper presents a communication-aware, game-theoretic coordination framework in which stations act as rational agents that iteratively adjust operating setpoints based on locally computed utilities. Existing station-level pressure controllers regulate local pressures and flows, while a slower supervisory negotiation layer governs inter-station coordination using steady-state hydraulic surrogates derived from pump affinity laws and pipeline loss relationships. The proposed framework does not rely on centralized optimization or exhaustive enumeration of strategies. Instead, stations update setpoints sequentially, evaluating …

Faculty, Staff and Students Publications

Retinal organoids represent a promising regenerative strategy for restoring vision in retinal degenerative diseases, but the capacity of host cone bipolar cells in the primate macula to rewire with transplanted photoreceptors has not been established. In this study, we transplanted genome-edited ISL1-/- human retinal organoids lacking ON-bipolar cells into an acute laser-induced macular photoreceptor ablation non-human primate model. Using immunohistochemistry, ultrastructural imaging, and focal macular electroretinography, we demonstrate that host rod and cone bipolar cells actively extend dendrites toward grafted photoreceptors and form synaptic contacts, with evidence of functional signal transmission in a subset of transplanted eyes. Longitudinal, per-eye analyses …

Accounting And Economic System Classification: An Adverse Effect Of The Misconceptualization Of Capital, Henry Zeno Chalu

Business Management Review

This paper discusses the influence of accounting on economic system classification. Particularly, it traces how a misconception of the accounting term ‘capital’ led to a misleading characterization of capitalism and socialism as inherently oppositional economic systems. This misunderstanding stems from neglect of the two complementary modes of thought on which accounting as a science rests: reasoning, which is the conceptual, idealistic dimension, and proving, which is the technical, physicalist dimension. Both modes are integral to the construction of most of the accounting terms used in economics. If an accounting conceptualization had been followed, capitalism and socialism would not …
