Moving Aggregate Modified Autoregressive Copula‐Based Time Series Models (MAGMAR‐Copulas)
Journal of Time Series Analysis, EarlyView.ABSTRACT Copula‐based time series models can model univariate and stationary time series in a flexible way by decomposing the joint distribution of consecutive observations into a copula and the stationary distribution. Implicitly, this approach assumes a finite Markov order. In reality, a time series may not follow the Markov property.

The approximate conformal mapping onto multiply connected domains
Проблемы анализа, 2019 The method of boundary curve reparametrization is generalized to the case of multiply connected domains. We construct the approximate analytical conformal mapping of the unit disk with N circular slits or an annulus with (N - 1) circular slits onto an ...

Long‐term stability of vertical bone augmentation in implant dentistry: A domain‐based review
Periodontology 2000, EarlyView.Abstract Objectives Vertical ridge deficiency remains one of the most challenging conditions in preimplant surgery. Several techniques aim to restore lost vertical alveolar height, each with specific indications and limitations. Although these procedures often yield favorable short‐term outcomes with stable bone levels, their long‐term performance is ...

The Journal of Physiology, EarlyView.Abstract figure legend Sex‐specific models of the human atrial myocyte in normal sinus rhythm (nSR) and chronic atrial fibrillation (cAF) revealed increased alternans susceptibility in cAF males and DADs in females, driven primarily by ICaL and ryanodine receptor remodelling.

Revista Ingenierías Universidad de Medellín, 2008 La reparametrización de las mallas triangulares es uno de los procesos fundamentales usados por casi todos los sistemas de procesamiento geométrico. La mayoría de trabajos se han enfocado en el remallado triangular; el problema igualmente importante de ...

Chiral kinetic theory from effective field theory revisited
Journal of High Energy Physics, 2019 We revisit the chiral kinetic equation from high density effective theory approach, finding a chiral kinetic equation differs from counterpart derived from field theory in high order terms in the O(1/μ) expansion, but in agreement with the equation ...

An Experiment‐Guided Descriptor Framework for Chain‐Growth CO2 Electrocatalysis
Angewandte Chemie Novit, Volume 2, Issue 3, September 2026.By bridging experiments with theoretical analyses, we establish a descriptor framework for CO2 electroreduction into long‐chain hydrocarbons (LCHC), which includes the barrier difference between *CO hydrogenation and *CO─*CO coupling, along with the barriers of *CO─*CH2 coupling and competing HER.

Medical Physics, Volume 53, Issue 8, August 2026.Abstract Background Detector frame rate is commonly used as the primary metric to characterize the temporal behavior of x‐ray detectors in medical imaging systems. However, frame rate alone specifies only the sampling rate of image frames and does not determine how x‐ray interaction signals are temporally integrated to form the measured signal within ...

Identifiable reparametrizations of linear compartment models
Journal of Symbolic Computation, 2014 Identifiability concerns finding which unknown parameters of a model can be quantified from given input-output data. Many linear ODE models, used in systems biology and pharmacokinetics, are unidentifiable, which means that parameters can take on an infinite number of values and yet yield the same input-output data. We use commutative algebra and graph
