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 With the market introduction of new reinforcing materials, such as corrosion‐resistant steel, the effect of their stress–strain relationship on the ductility of reinforced concrete structures needs to be evaluated. Their moment‐curvature behavior significantly influences bending moment redistributions, rotation capacity, and deformation at ...

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‐

Notes on the spaces of bilinear multipliers
, 2009 A locally integrable function $m(ξ,η)$ defined on $\mathbb R^n\times \mathbb R^n$ is said to be a bilinear multiplier on $\mathbb R^n$ of type $(p_1,p_2, p_3)$ if $$ B_m(f,g)(x)=\int_{\mathbb R^n} \int_{\mathbb R^n}\hat f(ξ)\hat g(η)m(ξ,η)e^{2πi(} dξdη$$ defines a bounded bilinear operator from $L^{p_1}(\mathbb R^n)\times L^{p_2}(\mathbb R^n) $ to $L ...

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 ...

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.

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

A secured cloud‐medical data sharing with A‐BRSA and Salp ‐Ant Lion Optimisation Algorithm
CAAI Transactions on Intelligence Technology, EarlyView.Abstract Sharing medical data among healthcare providers, researchers, and patients is crucial for efficient healthcare services. Cloud‐assisted smart healthcare (s‐healthcare) systems have made it easier to store EHRs effectively. However, the traditional encryption algorithms used to secure this data can be vulnerable to attacks if the encryption key

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.
