Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

open access: yesAdvanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Microfabricated Anisotropic Myobundles for the Scalable Production of Cardiac Tissue Grafts

open access: yesAdvanced Functional Materials, EarlyView.
Controlling the anisotropy of cardiac tissue remains an outstanding challenge in the field of cardiac tissue engineering. Here, we introduce an approach to generate anisotropic cardiac myobundles using cell‐adhesive, synthetic, electrospun fibers and stem cell‐derived cardiac fibroblasts.

DYNAMIC COMPLEMENTARITY IN EXPORT PROMOTION: THE MARKET ACCESS PROGRAM IN FRUITS AND VEGETABLES

open access: yes
To justify public subsidies for export promotion, export markets must fail to provide incentives for exporters to recognize the benefits of spillover or long-term benefits of promotion.

Exploring the Heterogeneous Effects of Export Promotion

open access: yesThe World Bank Economic Review, 2019
Abstract A semiparametric varying coefficient model is used to explore the heterogeneity in returns to export promotion across countries. Differences in characteristics of export-promotion agencies drive the heterogeneity in returns. Interestingly, characteristics that matter for export growth do not necessarily matter for GDP per capita

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis

open access: yesAdvanced Functional Materials, EarlyView.
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

EXPORT PROMOTION POLICY, PREREQUISITE OF AN EFFICIENT NATIONAL FOREIGN TRADE STRATEGY [PDF]

open access: yesChallenges of the Knowledge Society, 2012
The importance of international trade is widely recognized not only by the business sector, but also by governments. Governments all over the world have reviewed and streamlined their foreign trade strategies during the last decades. Nearly all countries

Relative Effectiveness of USDA's Nonprice Export Promotion Instruments

open access: yesJournal of Agricultural and Resource Economics, 2000
The USDA's Foreign Agricultural Service funds three types of activities to promote agricultural exports: consumer promotion, technical assistance, and trade servicing. These "instruments" are analyzed using an adaptation of Muth's model. Results indicate

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a
