Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.

FORMS OF GOVERNANCE AND THE SIZE OF RENT-SEEKING [PDF]

open access: yes
In this paper we present a model of an organization where agents can choose between productive and rent-seeking activities. We consider two governance institutions, single ownership and corporate governance or parliament rule. Applications include models

Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

open access: yesAdvanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

open access: yesAdvanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...

Rent-seeking with scarce talent: a model of preemptive hiring [PDF]

open access: yes
In the standard model of a rent-seeking contest, firms optimally employ resources in an attempt to win the contest and obtain the rent. Typically, it is assumed that these resources may be hired at any desired level at some fixed, exogenous per-unit cost.

Universal Gripper for Industrial Manipulation With Enhanced Rigid Mechanics and Self‐Adaptable Fingers

open access: yesAdvanced Robotics Research, EarlyView.
An enhanced universal gripper combining rigid mechanics with self‐adaptable fingers is presented for industrial automation. The novel six‐bar linkage with integrated compliant pad eliminates mechanical interference while enabling passive shape adaptation.

Incentive Compatible Extraction of Natural Resource Rent [PDF]

open access: yes
The exploitation of natural resources often generates considerable economic rent. Since such so-called resource rents accrue due to innate characteristics of the resource itself thus reflecting its eco-nomic value and not due to managerial abilities of ...

Indebted Abbots: The Impact of Lordly Demand on the Late Medieval Rural Economy in Northeast Scotland

open access: yesJahrbuch für Wirtschaftsgeschichte
Scottish historiography often describes late medieval Scotland as experiencing socio-economic stagnation while at the same time witnessing a shift from feudal to post-feudal lordship. This paper reevaluates that interpretation through a case study of the

CONCEPTUAL BASIS FOR THE FORMATION OF THE AGRICULTURAL LAND MARKET PURPOSES

open access: yesInternational Journal of Innovative Technologies in Economy, 2018
In this paper, the conceptual model that describes a wide range of phenomena and processes that will begin in Ukraine's economy after the abolition of the moratorium on land sales. Based on this model, a number of basic conclusions.
