Location of Gliomas in Relation to Mobile Telephone Use: A Case-Case and Case-Specular Analysis

2011

The energy absorbed from the radio-frequency fields of mobile telephones depends strongly on distance from the source. The authors' objective in this study was to evaluate whether gliomas occur preferentially in the areas of the brain having the highest radio-frequency exposure. The authors used 2 approaches: In a case-case analysis, tumor locations were compared with varying exposure levels; in a case-specular analysis, a hypothetical reference location was assigned for each glioma, and the distances from the actual and specular locations to the handset were compared. The study included 888 gliomas from 7 European countries (2000-2004), with tumor midpoints defined on a 3-dimensional grid …

Mutual entity authentication for LTE

2011

In this paper we outline the Authentication and Key Agreement protocol (EPS-AKA) found in Long-Term Evolution (LTE) systems. This architecture is the 3GPP version of a 4G access security architecture. The LTE security architecture is a mature evolved architecture, with both strengths and weaknesses. In this paper we propose an amendment to the EPS-AKA protocol to make it a full mutual (online) entity authentication protocol. We also analyze the proposal, highlighting both the improvements and the drawbacks of the new AKA protocol.

On Multiple AER Handshaking Channels Over High-Speed Bit-Serial Bidirectional LVDS Links With Flow-Control and Clock-Correction on Commercial FPGAs f…

2017

Address event representation (AER) is a widely employed asynchronous technique for interchanging “neural spikes” between different hardware elements in neuromorphic systems. Each neuron or cell in a chip or a system is assigned an address (or ID), which is typically communicated through a high-speed digital bus, thus time-multiplexing a high number of neural connections. Conventional AER links use parallel physical wires together with a pair of handshaking signals (request and acknowledge). In this paper, we present a fully serial implementation using bidirectional SATA connectors with a pair of low-voltage differential signaling (LVDS) wires for each direction. The proposed implementation …

An AER handshake-less modular infrastructure PCB with x8 2.5Gbps LVDS serial links

2014

Nowadays spike-based brain processing emulation is taking off. Several EU and others worldwide projects are demonstrating this, like SpiNNaker, BrainScaleS, FACETS, or NeuroGrid. The larger the brain process emulation on silicon is, the higher the communication performance of the hosting platforms has to be. Many times the bottleneck of these system implementations is not on the performance inside a chip or a board, but in the communication between boards. This paper describes a novel modular Address-Event-Representation (AER) FPGA-based (Spartan6) infrastructure PCB (the AER-Node board) with 2.5Gbps LVDS high speed serial links over SATA cables that offers a peak performance of 32-bit 62.5…

Analysis of proposals to reduce SAR levels from GSM terminals

2002

Is wireless communication dangerous? In recent years some scientists and lay people have expressed alarm at the possible harm mobile phones could cause to the user's health, even cancer. Handset terminals must meet standard limits based in SAR measurements. In this paper we present several proposals to minimize SAR values computed over a numerical user's head model using absorbent materials and new generation antennas.

Ein neues Fragment des Midrasch Bereschit Rabba

2021

Unter den in Archiven und Bibliotheken erhaltenen Einband- und Makulaturfragmenten bilden die auf Hebräisch beschrifteten Reste jüdischer Handschriften eine besondere Gruppe. Die Erforschung dieser jüdischen Fragmente erfährt seit einigen Jahren in Deutschland und auch in benachbarten europäischen Ländern zunehmende Beachtung. Dennoch sind viele Funde noch unbekannt und konnten daher etwa auch im Rahmen größerer Editionsprojekte nicht berücksichtigt werden. Ihre systematische Erfassung stellt daher nach wie vor eine wichtige Aufgabe dar und wird auch in den kommenden Jahren immer wieder interessante Entdeckungen auch an entlegenen Orten zu Tage fördern. Das hier vorgestellte Blatt wurde unl…
