This article is part of a For-Discussion-Section of Methods of Information in Medicine about the paper "Computational Electrocardiography: Revisiting Holter ECG Monitoring" written by Thomas M. Deserno and Nikolaus Marx. It is introduced by an editorial. This article contains the combined commentaries invited to independently comment on the paper of Deserno and Marx. In subsequent issues the di...

BACKGROUND The purpose of this study was to assess postsurgical outcomes in active patients after primary repair of acute and chronic proximal hamstring tears. HYPOTHESIS Surgical treatment of both acute and chronic proximal hamstring avulsion injuries would result in improved patient outcomes using validated outcome scores and a hamstring-specific questionnaire, and operative repair of these...

Despite his conviction on a morals charge involving a boy, the early German Social Democrat Johann Baptist von Schweitzer went on to have a successful political career. His life furnishes the context to present remarks by his political opponents Marx and Engels, which reveal their deep-seated homophobia. It is pointed out that this has been glossed over by the translations of the recently publi...

Decomposition of formaldehyde (HCHO) by a microplasma reactor in order to improve Indoor Air Quality (IAQ) was achieved. HCHO was removed from air using one pass through reactor treatment (5 L/min). From an initial concentration of HCHO of 0.7 ppm about 96% was removed in one pass treatment using a discharge power of 0.3 W provided by a high voltage amplifier and a Marx Generator with MOSFET s...

In January 1848, 160 years ago, Karl Marx added the finishing touches to a remarkable document, The Communist Manifesto. Umberto Eco has recently commended the admirable literary style and poetic qualities of this, probably the most influential political pamphlet ever written. But more than this, we should note again its author’s amazing prescience – prescient in terms of anticipating the main ...

The fundamental principles of modern dialectical philosophy derive from Hegel. He sums them up as follows. `Everything is inherently contradictory ... Contradiction is the root of all movement and vitality, it is only in so far as something has a contradiction within it that it moves, has an urge and activity' (Hegel 1969, 439). In Hegel's philosophy these ideas form part of an all-embracing id...

Compact Marx generators based on the wave-erection principle are ideal drivers for flash x-ray systems. Traditional Marx generator design techniques lead to slow rising voltage pulses, marked by high impedances, large temporal jitter values and inefficient transfer of energy. As a result, larger pulse generators are fabricated to overcome these shortcomings, which results in excessive volumes a...

Democracy: Marx’s theory of history (ex. Organization of the mode of production determines superstructure; unequal distribution of labor) explains the lack of actual democracy in capitalist societies; however, Marx’s thought concerning progression (also a theory of history) states that capitalist societies would eventually progress to a democratic state after a revolution of the proletariat. Ma...

At the time Marx was writing, metaphysics was in the grip of a dualism that separated mind from matter and, under the influence of Christian theology, often exaggerated a distinction into an antagonism; in such a world-view, body and soul were seen as warring parties with the body cast as the villain of the piece. Marx rejected the dualist philosophy and stressed that not only was there an inti...

In this paper we present the design for a low-cost RF cavity capable of accelerating protons from 100 keV to 1MeV. The system is designed to meet the specifications from the proposed Alceli LTDmedical proton therapy linac, to deliver a 1 nA proton beam current with a 1 kHz repetition rate. We present a design of an RF normal conducting (NC) re-entrant Cu cavity operating at 40MHz consisting of ...
