TRADE BALANCE AND TERMS OF TRADE RELATIONSHIP: Evidence from Pakistan [PDF]
Pakistan Journal of Applied Economics, 2018 The terms of trade (TOT) have an important role in determining direction of the trade which finally transmits into trade balance. The current study is an effort to seek the effect of TOT on the trade balance.

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus
Advanced Functional Materials, EarlyView.The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...

THE PRODUCTION THEORY APPROACH TO IMPORT DEMAND ANALYSIS: A COMPARISON OF THE ROTTERDAM MODEL AND THE DIFFERENTIAL PRODUCTION APPROACH [PDF]
Results indicate that, when comparing the unconditional derived-demand elasticities to the unconditional consumer demand elasticities, significant differences emerge due to the differences in the first-stage estimation procedure between the differential ...

Encoding Magnetic Anisotropies in Digital Light Processing 3D Printing
Advanced Functional Materials, EarlyView.A hybrid magnetic device—combining a coaxial coil within a nested Halbach array—is presented, integrated into a DLP 3D printer to enable spatially resolved magnetic field control. This system enables complex, multimodal responses by programming liquid crystal elastomer resins for magnetic and thermal actuation, and by inducing electrically conductive ...

The US Trade Deficit: A Disaggregated Perspective [PDF]
The paper prepares new estimates for the elasticity of US trade flows using bilateral, commodity-detailed trade data for 31 countries, using measures of expenditure and trade prices matched to commodity groups, and including a commodity-and-country ...

Advanced Functional Materials, EarlyView.Permanent magnets derive their extraordinary strength from deep, universal electronic‐structure principles that control magnetization, anisotropy, and intrinsic performance. This work uncovers those governing rules, examines modern modeling and AI‐driven discovery methods, identifies critical bottlenecks, and reveals electronic fingerprints shared ...
