Transcritique: On Kant and Marx

Kojin Karatani's Transcritique introduces a startlingly new size to Immanuel Kant's transcendental critique through the use of Kant to learn Karl Marx and Marx to learn Kant. In an instantaneous problem to plain educational techniques to either thinkers, Karatani's transcritical readings notice the moral roots of socialism in Kant's Critique of natural cause and a Kantian critique of cash in Marx's Capital.

Non-Identifier-Based High-Gain Adaptive Control

During the last decade the sphere of adaptive keep an eye on the place no id mechanisms are invoked has turn into an incredible examine subject. This booklet provides a cutting-edge file at the following extra particular quarter: the procedure periods into account comprise linear (possibly nonlinearly perturbed), finite dimensional, non-stop time structures that are stabilizable by way of high-gain output suggestions.

The Resonant Recognition Model of Macromolecular Bioactivity: Theory and Applications

Organic techniques in any residing organism are in line with selective interactions be­ tween specific biomolecules. generally, those interactions contain and are pushed by way of proteins, that are the most conductors of any existence approach in the organism. The actual nature of those interactions continues to be no longer renowned.

For a given Smarandache sequence a(n) evaluate lim n→ ∞ ∑ n Su ( n) where s ∈ N ns Is there any Smarandache sequence a(n) such that its Smarandache Zeta function Sz(n) is related to this sum? Problem 16. Evaluate for some Smarandache sequence a(n): ∞ ∑ n=1 Su (n ) ⋅ ln(a (n)) a (n) Is it convergent? 19) Smarandache Mertens Function Analogously to the Mertens function in number theory [5] we can define the following function: n Sm (n ) = ∑ k =1 48 Su (k ) where Su(k) is the Smarandache Mobius function applied to any Smarandache sequence a(k).

2 ⋅ (1 − 2 ) + g − ln(4 ⋅ π ) Ss(n ) ≤ eg + a( n) ⋅ ln(ln( a( n))) ln(a (n)) ⋅ ln(ln( a(n ))) where g is the Smarandache Euler-Mascheroni constant for the sequence a(n). This question is well formulated if the hypothesis that the Smarandache sequence a(n) converges to a g constant value is satisfied. Problem 26 . For any Smarandache sequence evaluate: 1 N N ∑ ∑ ∑ Ss (k ) k =1 lim k →∞ k lim k →∞ 1 Ss (k ) Ss(k ) k 26) Smarandache prime factors function The Smarandache prime factors is defined for any Smarandache sequence a(n) as: Spf(n)=r(a(n)) where r(a(n)) is the number of distinct prime factors of a(n) [5].

Is there any Smarandache sequence a(k) like the cubic-product one such that SR is close to an integer? Notice also that the product: F = π 4⋅S can produce numbers almost integer. 728831.... 994765....... 615792.... 983738....... 913745.... 007069....... 513624.... 031646....... 239704.... 75843....... If F is close to an integer we call it a Smarandache almost integer. Problem 19. Is there any Smarandache sequence a(n) that produce other Smarandache almost integers?
