SeismicaWe apply adjoint waveform tomography using Rayleigh wave Empirical Green's Functions (EGFs) at 10-50 sec. periods to improve a prior 3D velocity model of the crust and uppermost mantle beneath the Iranian Plateau.

On Bending in the As‐Rigid‐As‐Possible Deformation Energy
Computer Graphics Forum, EarlyView.Abstract The well‐established As‐Rigid‐As‐Possible (ARAP) energy has various forms. For surface deformation, commonly used energies contain an implicit bending penalty. We present a natural, continuous generalization that incorporates multiple ARAP versions with an implicit, user‐controllable bending penalty.

Attention Based Optimization for 3D Shape Registration
Computer Graphics Forum, EarlyView.Abstract Transformers are sequence‐to‐sequence architectures originally designed to handle structurally rigid and order‐sensitive data, such as text and images. At their core, they exploit the attention mechanism, which is permutation‐equivariant and relies on computing token‐to‐token relationships.

A Continuous Adjoint Framework For Vehicle Aerocoustic Optimization
, 2018 This paper presents a novel adjoint-based methodology for vehicle aeroacoustic optimization. The adjoint sensitivity map on the side mirror is computed, which indicates how its geometry should change in order to reduce the wind noise transmission into the vehicle interior.

Fluid Control with Localized Spacetime Windows
Computer Graphics Forum, EarlyView.Abstract We present a physics‐based fluid control method utilizing localized spacetime windows, extending force‐based fluid control to substantially larger simulation scales. In many practical editing scenarios, user‐specified objectives affect only a small region of an otherwise satisfactory simulation, resulting in optimal control force distributions

The Evolution of Interest‐Rate Models: From the Yield Curve to the Swaption Cube
Journal of Economic Surveys, EarlyView.ABSTRACT Interest‐rate modelling is often taught as a catalogue of competing stochastic equations, obscuring why models were created and why modern sell‐side desks use several simultaneously. This survey reorganises the field around five layers of a pricing architecture: curve construction; arbitrage‐free dynamics; volatility‐smile representation ...

Optimal Portfolio Choice With Cross‐Impact Propagators
Mathematical Finance, EarlyView.ABSTRACT We consider a class of optimal portfolio choice problems in continuous time where the agent's transactions create both transient cross‐impact driven by a matrix‐valued Volterra propagator, as well as temporary price impact. We formulate this problem as the maximization of a revenue‐risk functional, where the agent also exploits available ...

Coordinating Bank Dividend and Capital Regulation
Mathematical Finance, EarlyView.ABSTRACT This paper examines how state‐dependent dividend restrictions (taxes and bans) and capital requirements influence a bank's capital buffer accumulation and risk‐taking decisions. In the model, the bank distributes dividends and issues costly equity to maximise shareholder value, while its loans generate stochastic income under time‐varying ...
