Complex-Valued Orthogonal Unitary Superposition Encoding for Robust Three-Qubit Quantum-Error-Correction-Based Image Transmission

Algorithms
Efficient and reliable transmission of compressed images over noisy channels remains a significant challenge due to the high sensitivity to noise. Quantum communication offers a promising solution by encoding classical information into quantum states ...

Optimal Homogeneous ℒp$$ {\boldsymbol{\mathcal{L}}}_{\boldsymbol{p}} $$‐Gain Controller

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Nonlinear ℋ∞$$ {\mathscr{H}}_{\infty } $$‐controllers are designed for arbitrarily weighted, continuous homogeneous systems with a focus on systems affine in the control input. Based on the homogeneous ℒp$$ {\mathcal{L}}_p $$‐norm, the input–output behavior is quantified in terms of the homogeneous ℒp$$ {\mathcal{L}}_p $$‐gain as a ...

Towards a Sustainable Future: The Role of Technological Innovation and Digitalization in European Union Climate Change Mitigation

Sustainable Development, EarlyView.
ABSTRACT Technological innovation and digitalization are widely viewed as key drivers of sustainable development, yet their effectiveness in reducing carbon emissions remains uncertain. This study examines how technological innovation, digitalization, energy structure, and economic activity shape both CO2 emissions and total factor productivity in 22 ...

Business Model and Sustainable Development Goals for an Innovative Agricultural Waste Management: Distributed Biogas Production

Sustainable Development, EarlyView.
ABSTRACT Technological progress and population growth have increased global pork demand; leading to a rise of methane emission from pig farming, a key contributor to climate change. Anaerobic digestion offers a sustainable solution by converting manure into biogas.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

H-UNITARY AND LORENTZ MATRICES: A REVIEW

, 2008
. Many properties of H-unitary and Lorentz matrices are derived using elementary methods. Complex matrices which are unitary with respect to the indefinite inner product induced by an invertible Hermitian matrix H, are called H-unitary, and real matrices

The Legacies of Lockdown: Moral Logics of Exchange and Mistrust in Postpandemic China

Economic Anthropology, EarlyView.
ABSTRACT When Shanghai entered an extended lockdown under China's Zero‐COVID policy in spring 2022, residents found themselves confined within their residential compounds, cut off from conventional supply chains, and dependent on improvised systems of local provisioning and state rationing. From the perspective of economic anthropology, such conditions
