Precision Radiation Oncology, EarlyView.We propose R3Net, a decoder‐free medical image segmentation framework that recursively refines multiscale representations within the encoder using residual pathways. R3Net achieves competitive accuracy with reduced model complexity and improved computational efficiency across multiple medical imaging modalities.

Bilinear multipliers on Lorenzt spaces
, 2007 We give one sufficient and two necessary conditions for boundedness between Lebesgue or Lorentz spaces of several classes of bilinear multiplier operators closely connected with the bilinear Hilbert transform.

On the existence of linear and bilinear multipliers on Lorentz spaces [PDF]
Mathematical Inequalities & Applications, 2011 First we show that any translation invariant bounded linear operator from Lp,t(R) the Lorentz space on R to Lp,s(R) (1 < p < ∞, 1 s < t < ∞) is trivial, whose result improves Blozinski’s result [4]. Next let φ be a bounded continuous function on R2 , and Tφ ( f ,g)(x) = ∫ ∫ φ(ξ ,η) f (ξ )ĝ(η)eix(ξ+η)dξdη the bilinear operator on Lorentz spaces.

New views of some invariants associated with the Cartesian 2D velocity gradient tensor
Quarterly Journal of the Royal Meteorological Society, EarlyView.Vorticity and divergence of horizontal flow are fundamental quantities in meteorology; both are linear functions of the four elements of the 2D velocity gradient tensor and both are formally unchanged under coordinate rotation. We explore four quadratic functions of the elements that are geometrically invariant in this sense, finding some novel ...

Toward a theory of Bayesian experimentation in early‐stage ventures
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary The entrepreneurship literature has established the benefits of experimentation but has paid comparatively little attention to its costs. We develop a Bayesian model to illustrate the entrepreneurial choice between direct and experimental entry.

Structural Concrete, EarlyView.Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Rotation capacity of continuous reinforced concrete slab strips revisited
Structural Concrete, EarlyView.Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns
Structural Concrete, EarlyView.Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

Flexural behavior of precast prestressed slabs with embedded building service systems
Structural Concrete, EarlyView.Abstract Dry‐assembled precast concrete construction is rapidly spreading in many parts of the world due to the several advantages offered by industrialized construction. In order to speed up not only the assemblage of the structure, but also the full integrated building process, engineering systems (mechanical–electrical–plumbing) may be prefabricated
