Conditions for regular $B$-spline curves and surfaces [PDF]

open access: yesESAIM: Mathematical Modelling and Numerical Analysis, 1992
A curve with \(C^ 1\) components is said to be regular if it has a continuous unit tangent and if it has no self-intersections. In the paper under review the new sufficient conditions for the regularity of a B- spline curve in \(\mathbb{R}^ d(d>1)\) are derived. Extensions to tensor product B-spline surfaces are also discussed.

Systolic algorithms for B-spline patch generation

open access: yes, 1991
A systolic array for constructing the blending functions of B-spline curves and surfaces is described and shown to be 7k times faster than the equivalent sequential computation.

Inverse Design of Pre‐Strain via a Predictive Electromechanical Model for Enhanced Strain Sensing

open access: yesAdvanced Science, EarlyView.
An analytical electromechanical model rooted in microcrack evolution mechanics is globally calibrated from only eight pre‐strain datasets, enabling prediction of the complete sensing response at untested pre‐strain values within the calibrated design space (R2 > 0.99).

Surface profile prediction and analysis applied to turning process [PDF]

open access: yes, 2008
An approach for the prediction of surface profile in turning process using Radial Basis Function (RBF) neural networks is presented. The input parameters of the RBF networks are cutting speed, depth of cut and feed rate.

Enhancing Near‐Room‐Temperature Thermoelectric Performance of n‐Type Mg3(Sb, Bi)2‐Based Materials via ZrB2 Heterointerface Engineering

open access: yesAdvanced Science, EarlyView.
A conductive ZrB2 ceramic composite strategy was developed for Mg3(Sb, Bi)2 thermoelectrics to regulate carrier transport and phonon scattering through heterointerface engineering. The 1.0 wt.% ZrB2 composite achieved enhanced room‐temperature performance, with a power factor of 28.51 µW cm−1 K−2 and a peak ZT of 1.22 at 573 K.

Precise Control of Charge–Structure Coupling in Polyamide Membranes for Mono‐ and Divalent Ion Separation

open access: yesAdvanced Science, EarlyView.
A zwitterionic copolymer, Poly(2‐methacryloyloxyethyl phosphorylcholine‐co‐2‐aminoethyl methacrylate hydrochloride) (P(MPC‐co‐AEMA)) copolymers, with tunable MPC/AEMA ratios, is grafted onto the polyamide (PA) selective layer via secondary interfacial polymerization. Balancing reactive anchoring segments (AEMA) and zwitterionic segments (MPC) regulated

Bridging Horizontal to Vertical Radiative Cooling

open access: yesAdvanced Science, EarlyView.
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Sequential Patterning of Photoresponsive Hydrogels Directs Crypt Fission and Reveals the Role of Epithelial Curvature on Fission Symmetry

open access: yesAdvanced Science, EarlyView.
Deterministic crypt fission is achieved in intestinal organoids using photopatternable hydrogels with spatiotemporal control. Daughter‐crypt symmetry is shown to depend on parent‐crypt geometry and epithelial curvature, while myosin‐dependent mechanosensing links tissue shape to regenerative outcomes.
