On the Relationship Between Exchange Rates and Interest Rates: Evidence from the Southern Cone [PDF]

open access: yes
This paper provides a closer view on the interaction of exchange rate volatility and interest rate volatility in the Mercosur countries. We discuss several models that explain systematic correlations between the movements of both variables and their ...

Second mode unstable disturbance measurement of hypersonic boundary layer on cone by wavelet transform

open access: yes, 2011
Experimental investigation of hypersonic boundary layer instability on a cone is performed at Mach number 6 in a hypersonic wind tunnel. Time series signals of instantaneous fluctuating surface-thermal-flux are measured by Pt-thin-film thermocouple ...

Soft, Degradable, and Magnetic Microcarriers for Encapsulation and Guided Transport of Drugs and 3D Spheroids

open access: yesAdvanced Materials, EarlyView.
This work presents soft, degradable hydrogel microcarriers that combine magnetic responsiveness with the ability to host multiple therapeutic and cellular components. Produced by droplet microfluidics, the carriers maintain structural integrity during manipulation, permit controlled breakdown under physiological conditions, and enable guided motion for

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum

open access: yesAdvanced Materials, EarlyView.
Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

A Dual‐Bioresponsive and Programmable Microneedle Matrix as a Bioinspired Coupler for Orchestrating Diabetic Bone Regeneration

open access: yesAdvanced Materials, EarlyView.
This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.

Clustering of Trading Activity in the DAX Index Options Market [PDF]

open access: yes
Trades in DAX index options with identical maturities cluster around particular classes of strike prices. For example, options with strikes ending on 50 are less traded than options with strikes ending on 00.

Biodegradable Chitosan Films as Green Resists for Gold Nanowires Fabrication Through AFM‐Based Nanolithography

open access: yesAdvanced Materials Interfaces, EarlyView.
Schematic illustration of a sustainable nanofabrication process: chitosan derived from natural sources is used as a biodegradable thin film resist, patterned via Constant Pulse‐Assisted Force Lithography (CP‐AFL) to create tunable nanogrooves. These grooves template gold nanowire formation, enabling high‐resolution nanopatterning under ambient ...

An Injectable Electroactive Hydrogel Engineered for Stable Bioelectronic Interfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Injectable electroconductive hydrogels enable soft, conformal, and stable bioelectronic interfaces for electroceutical therapies. A catechol‐modified hyaluronic acid/alginate/edge‐functionalized graphene platform combines wet adhesion, shear‐thinning injectability, tissue‐matched mechanics, and electrochemical functionality.
