Playing with Derivation Modes and Halting Conditions [PDF]
, 2019 In the area of P systems, besides the standard maximally parallel derivation mode, many other derivation modes have been investigated, too. In this paper, many variants of hierarchical P systems and tissue P systems using different derivation modes ...

Black Hole Entropy in the Chern-Simons Formulation of 2+1 Gravity
, 1997 We examine Carlip's derivation of the 2+1 Minkowskian black hole entropy. A simplified derivation of the boundary action -valid for any value of the level k- is given.Comment: 6 pages, RevTeX, minor changes.

Discrete Mathematics, 1999 AbstractWe provide short proofs that suitable unitals in derivable projective planes give rise to unitals in the derived planes. Some known constructions of unitals in Hall planes are immediate corollaries.

Dendritic cells steering antigen and leukocyte traffic in lymph nodes
FEBS Letters, EarlyView.Dendritic cells are key players in the activation of T cells and their commitment to effector function. In this In a Nutshell Review, we will discuss how dendritic cells guide the trafficking of antigen and leukocytes in the lymph node, thus influencing T‐cell activation processes. Dendritic cells (DCs) play a central role in initiating and shaping the

Deviant expansion of neoanthroponyms in the speech of social media users
Вісник Харківського національного університету імені В. Н. Каразіна. Серія Філологія. Vìsnik Harkìvsʹkogo nacìonalʹnogo unìversitetu ìmenì V.N. Karazìna. Serìâ Fìlologìâ., 2023 The article analyzes modern ways of creating occasional anthroponyms in political media discourse as linguistic triggers of the slang level, aimed at modeling a certain type of perception of reality by the recipient, laid down and provided by the creator-

DERIVATES, APPROXIMATE DERIVATES AND POROSITY DERIVATES OF n-CONVEX FUNCTIONS [PDF]
Real Analysis Exchange, 2001 It is shown that if $f$ is $n$-convex then the four $n$th order Peano derivates of $f$ are respectively equal to the corresponding $n$th order approximate Peano derivates and the porosity Peano derivates of $f$. It is further shown that the same result holds for the de la Vall\'ee Poussin derivates, and the symmetric and unsymmetric Riemann derivates.

The dual nature of TDC – bridging dendritic and T cells in immunity
FEBS Letters, EarlyView.TDC are hematopoietic cells combining dendritic and T cell features. They reach secondary lymphoid organs (SLOs) and peripheral organs (liver and lungs) after FLT3‐dependent development in the bone marrow and maturation in the thymus. TDC are activated and enriched in SLOs upon viral infection, suggesting that they might play unique immune roles, since

Derivation of effective evolution equations from many body quantum dynamics
, 2009 We review some recent results concerning the derivation of effective evolution equations from first principle quantum dynamics. In particular, we discuss the derivation of the Hartree equation for mean field systems and the derivation of the Gross ...

A New Measure of Monetary Shocks: Derivation and Implications
, 2003 Conventional measures of monetary policy, such as the federal funds rate, are surely influenced by forces other than monetary policy. More importantly, central banks adjust policy in response to a wide range of information about future economic ...
