Representations of Dirac Structures and Implicit Port-Controlled Lagrangian Systems [PDF]

, 2008
In this paper, we will develop two different representations for induced Dirac structures and their associated IPCL systems; namely, (1) a standard representation with using Lagrange multipliers; and (2) a representation without using Lagrange ...

Digital Rights Activism in Multilevel Governance

European Policy Analysis, EarlyView.
ABSTRACT Multilevel governance (MLG) without a clear hierarchical structure can create power imbalances among various actors, particularly in settings with overlapping jurisdictions and policy areas. This dynamic is especially pronounced in Internet governance, which faces a complex interplay of domestic laws, state interdependence, and heightened ...

Generic Modeling and Control Framework for Power Systems Dominated by Power Converters Connected Through a Passive Transmission and Distribution Grid

CSEE Journal of Power and Energy Systems
In this paper, a compact mathematical model having an elegant structure, together with a generic control framework, are proposed for generic power systems dominated by power converters that are interconnected through a passive transmission and ...

When Rare Is Not Small: Amyotrophic Lateral Sclerosis Initiatives and Therapy

Exploration, EarlyView.
In the precision‐medicine era, rare diseases must not be sidelined in translational infrastructure. The Mr. Cai Lei—led “Ice‐Breaking Team” turns an amyotrophic lateral sclerosis patient community into a sustainable ecosystem, realigning philanthropy, data, and research and development to reshape rare‐disease pipelines and guide precision therapies ...

Heat Transfer Performance of Biphilic Surfaces With Diatomite‐Based Composite Coatings in a Closed Thermosyphon System

Heat Transfer, EarlyView.
ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

Association between annual twin delivery volume and severe postpartum hemorrhage in twin pregnancies

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To assess the association between the risk of severe postpartum hemorrhage (PPH) and the annual twin delivery volume of maternity units. Methods JUmeaux MODe d'Accouchement (JUMODA) was a national observational prospective population‐based cohort of twin deliveries in 176 French maternity units performing more than 1500 annual ...

Sensitivity‐Tunable Complex Permittivity Sensing Enabled by Bound States in the Continuum in a Waveguide‐Resonator System

Laser &Photonics Reviews, EarlyView.
This work introduces two types of bound states in the continuum (BICs) and their merging in a waveguide‐resonator system, which significantly enhances the quality factor (Q$Q$). Benefiting from the high‐Q$Q$ characteristics of quasi‐BICs, a sensitivity‐tunable complex permittivity sensor is developed based on this system, achieving improvements of 93 ...

Topological Photonic Devices and Circuits at Terahertz Frequencies

Laser &Photonics Reviews, EarlyView.
This review examines how 3D topological insulators and emerging topological photonic phases enable robust, low‐loss and defect‐immune terahertz devices. Fundamental properties, device implementations and topological transport mechanisms are surveyed, revealing new opportunities for reconfigurable, high‐performance THz components and scalable ...

Convergence Deficits in Myoclonus‐Dystonia Point to Cerebellar Impairment

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.

Exact Quantization of Nonreciprocal Quasilumped Electrical Networks

Physical Review X
Following a consistent geometrical description previously introduced [Quantum 8, 1466 (2024)2521-327X10.22331/q-2024-09-09-1466], we present an exact method for obtaining canonically quantizable Hamiltonian descriptions of nonlinear, nonreciprocal ...
