Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

International outsourcing and incomplete contracts [PDF]

Canadian Journal of Economics/Revue canadienne d'économique, 2005
Abstract.  International outsourcing to lower cost countries such as China and India can best be understood through the enrichment of trade models to include concepts from industrial organization and contract theory that explain the vertical organization of production.

Multi‐Ion Doping Controlled CEI Formation in Structurally‐Stable High‐Energy Monoclinic‐Phase NASICON Cathodes for Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
The graphical abstract illustrates the synthesis pathway, morphological feature, and thermodynamic feasibility of entropy‐engineered NASICON cathodes for sodium‐ion batteries. Abstract Overcoming the energy density limitations of sodium‐ion batteries (NIBs) requires innovative strategies to optimize cathode materials.

Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation

Advanced Functional Materials, EarlyView.
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.

Experiences from Procurement of Integrated Bridge Maintenance in Sweden

European Journal of Transport and Infrastructure Research, 2009
The trend in many countries is to outsource maintenance with competitive tendering. The design of the tender is then a crucial issue. A new type of tendering contract, called "Integrated Bridge Maintenance", was introduced in one experimental area in ...

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Methodes of Contract Determination [PDF]

پژوهش های حقوق تطبیقی
In concluding a contract, sometimes we need to leave some of its provisions to the future and agree on the basic elements of the contract. Many lawyers consider this contract vague and even invalid.

Foreign Market Entry Under Incomplete Contracts [PDF]

SSRN Electronic Journal, 2010
AbstractThis paper shows that incomplete contracts serve as a determinant of the mode of foreign market entry – that is exports versus foreign direct investment (FDI). When contracts between two agents within a firm are too costly to be written, the share of multinational firms may be higher or lower compared with a world without contractual frictions.
