Versatile optical access to the tunnel gap in a low-temperature scanning tunneling microscope

We developed a setup that provides three independent optical access paths to the tunnel junction of an ultrahigh vacuum low temperature (4.2 K) scanning tunneling microscope (STM). Each path can be individually chosen to couple light in or out, or to image ...

On selecting the best transmission mode for WiFi devices

The design of efficient IEEE 802.11 physical (PHY) rate adaptation algorithms is a challenging research topic and usually the issues surrounding their implementations on real 802.11 devices are not disclosed. In this paper, we identify and evaluate the key ...

Explanatory Variables for per Capita Stocks and Flows of Copper and Zinc

Claudia Rebeca Binder Signer

A number of potential explanatory variables for the stocks and flows of copper and zinc in contemporary technological societies are co-analyzed with the tools of exploratory data analysis. A one-year analysis (circa 1994) is performed for 50 countries that ...

A Subthreshold SCL Based Pipelined Encoder for Ultra-Low Power 8-bit Folding/Interpolating ADC

Seyed Armin Tajalli, Yusuf Leblebici, Mohammad Beikahmadi

The subthreshold MOS source-coupled logic (STSCL) technique is of great interest for designing ultra low power circuits. In this paper we discuss the design of a pipelined encoder for an 8-bit folding and interpolating (F&I) analog-to-digital (ADC) data co ...

Switch-peptides: design and characterization of controllable super-amyloid-forming host-guest peptides as tools for identifying anti-amyloid agents

Hilal Lashuel, Adrian Schmid, Sonia Dos Santos, Marie-Stéphanie Camus

Several amyloid-forming proteins are characterized by the presence of hydrophobic and highly amyloidogenic core sequences that play critical roles in the initiation and progression of amyloid fibril formation. Therefore targeting these sequences represents ...

Actors that Unify Threads and Events

Martin Odersky, Philipp Haller

In practice, concurrent programming systems based on message passing are often instantiations of the actor model. A popular implementation of this form of concurrency is the Erlang programming language. Erlang supports massively concurrent systems such as ...

Eikonal approximation in AdS/CFT: Conformal partial waves and finite N four-point functions

We introduce the impact parameter representation for conformal field theory correlators of the form A similar to (O1O2O1O2). This representation is appropriate in the eikonal kinematical regime, and approximates the conformal partial wave decomposition in ...

A field investigation of the intermediate light switching by users

David Lindelöf, Nicolas Morel

This paper describes how data collected during a continuously running data acquisition program on the LESO building in Lausanne, Switzerland, was used to measure the intermediate light switch probability by users as a function of current illuminance levels ...

Routing Aware Switch Hardware Customization for Networks on Chips

Giovanni De Micheli, Srinivasan Murali

Networks on Chip (NoC) has been proposed as a scalable and reusable solution for interconnecting the ever- growing number of processor/memory cores on a single silicon die. As the hardware complexity of a NoC is significant, methods for designing a NoC wit ...

Joint source-channel coding with feedback

Communications is about conveying information from one point to another subject to certain performance constraints. The information is assumed to be generated by a source and may, for example, represent a voice waveform, the reading of a thermal sensor, or ...
