Role of density inhomogeneity in dissipative collapse through Finch-Skea spacetime in f(R) gravity
Nuclear Physics BThis study investigates the dynamics of dissipative gravitational collapse within the framework of f(R) gravity, focusing on the exponential correction model f(R)=R−β1Rs(1−e−R/Rs) and incorporating the concept of a horizon function. The model considers a

String theory at order α′ 2 and the generalized Bergshoeff-de Roo identification
Journal of High Energy Physics, 2021 It has been shown by Marques and Nunez that the first α′-correction to the bosonic and heterotic string can be captured in the O(D, D) covariant formalism of Double Field Theory via a certain two-parameter deformation of the double Lorentz ...

String Scattering from D-branes in Type 0 Theories
, 1999 We derive fully covariant expressions for all two-point scattering amplitudes involving closed string tachyon and massless strings from Dirichlet brane in type 0 theories.

Non-Planar String Networks on Tori [PDF]
, 2000 Type II strings in D=5 contain particle-like 1/8 supersymmetric BPS states. In this note we give a string-network representation of such states by considering (periodic) non-planar $(p,q,r)$-string networks of eight dimensional type II string theory on ...

Advanced Materials Technologies, EarlyView.This study describes the fabrication of arrays of luminal tissue constructs for 3D luminal tissue modeling. An oil or media‐filled reservoir between constructs serves as a liquid barrier or bridge to regulate communication between lumens within the array for modeling multi‐tissue interactions in vitro. Abstract Cell‐lined luminal structures are crucial

On the effective theory of long open strings
, 2010 We study the general low-energy effective action on long open strings, such as confining strings in pure gauge theories. Using Lorentz invariance, we find that for a string of length R, the leading deviation from the Nambu-Goto energy levels generically ...

Scalable Task Planning via Large Language Models and Structured World Representations
Advanced Robotics Research, EarlyView.This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...

Dilaton black hole entropy from entropy function formalism
European Physical Journal C: Particles and Fields, 2019 It has been shown that the entropy function formalism is an efficient way to calculate the entropy of black holes in string theory. We check this formalism for the extremal charged dilaton black hole. We find the general four-derivative correction on the

Spinning strings in AdS_5 x S^5: one-loop correction to energy in SL(2) sector
, 2005 We consider a circular string with spin $S$ in $AdS_5$ wrapped around big circle of $S^5$ and carrying also momentum $J$. The corresponding N=4 SYM operator belongs to the SL(2) sector, i.e. has tr$(D^S Z^J)+...$ structure.

AdS/CFT v.s. String Loops [PDF]
, 2006 The one string-loop correction to the energies of two impurity BMN states are computed using IIB light-cone string field theory with an improved 3-string vertex that has been proposed by Dobashi and Yoneya.
