Estimating Discharge From Undular Hydraulic Jumps: Feasibility Assessment Based on Flume Experiments
Water Resources Research, Volume 62, Issue 3, March 2026.Abstract Rapids are common in steep rivers, often forming where flow transitions from supercritical (Froude number, Fr > 1) to subcritical (Fr < 1) through a hydraulic jump. When upstream Fr is supercritical but close to 1, this transition may occur as an undular hydraulic jump, exhibiting a train of stationary waves downstream of the jump toe ...

Thermodynamic properties of the Dicke model in the strong-coupling regime
, 2005 We discuss the problem of a N two-level systems interacting with a single radiation mode in the strong-coupling regime. The thermodynamic properties of Dicke model are analyzed developing a perturbative expansion of the partition function in the high ...

Another Leigh-Strassler deformation through the Matrix model [PDF]
, 2003 In here the matrix model approach, by Dijkgraaf and Vafa, is used in order to obtain the effective superpotential for a certain deformation of N=4 SYM discovered by Leigh and Strassler.

IET Cyber-Systems and Robotics, Volume 8, Issue 1, January/December 2026.ABSTRACT Reduced‐order models (ROMs) are widely employed in biped robot control due to their computational efficiency, but their simplified representations often neglect critical nonlinear dynamics, leading to limited robustness under real‐world disturbances.

Discretized Thermal Green's Functions
, 2011 We present a spectral weight conserving formalism for Fermionic thermal Green's functions that are discretized in imaginary time and thus periodic in imaginary ("Matsubara") frequency. The formalism requires a generalization of the Dyson equation and the

Dynamical Optical Structure Solutions of the Time‐Fractional Chen‐Lee‐Liu Equation
Advances in Mathematical Physics, Volume 2026, Issue 1, 2026.In this article, we utilize the conformable fractional (CF) derivative to investigate the analytically innovative soliton solutions for the time‐fractional nonlinear perturbed Chen‐Lee‐Liu (CLL) equation in optical fibers. An essential governing equation in nonlinear optics, the perturbed CLL model describes the propagation of ultrashort pulses in ...

Advances in Mathematical Physics, Volume 2026, Issue 1, 2026.In this article, a highly generalized way of studying nonlinear evolution equations (NLEEs) with time‐dependent variable coefficients is provided. The innovative exact solutions of the Kadomtsev–Petviashvili (KP) equation and the modified Korteweg–de Vries (mKdV) equation with temporal variable coefficients are evaluated by using the extended ...

Matching the circular Wilson loop with dual open string solution at 1-loop in strong coupling
, 2008 We compute the 1-loop correction to the effective action for the string solution in AdS_5 x S^5 dual to the circular Wilson loop. More generically, the method we use can be applied whenever the two dimensional spectral problem factorizes, to regularize ...
