Human phospholipid scramblase 1 (hPLSCR1), a type II integral class membrane protein, is known to mediate bidirectional scrambling of phospholipids in a Ca(2+)-dependent manner. hPLSCR2, a homolog of hPLSCR1 that lacks N-terminal proline-rich domain (PRD), did not show scramblase activity. We attribute this absence of scramblase activity of hPLSCR2 to the lack of N-terminal PRD. Hence to invest...

Long-Distance Scrambling is a word-order phenomenon which is “doubly unbounded” in that (i) more than one element can move, and (ii) movement can be unbounded. In (Becker et al., 1991), we argue that scrambling is beyond TAG by assuming that elementary trees express a complete predicate-argument structure. In (Becker et al., 1992), we show that no formalism in the class LCFRS (which includes TA...

Scrambling is the delocalization of quantum information over a many-body system and underlies all quantum-chaotic dynamics. We employ discrete cellular automata as classically simulable toy models scrambling. observe that these break ergodicity, i.e., they exhibit scarring. also find time scale scrambling rises with local Hilbert-space dimension obeys specific combinatorial pattern. then show s...

Investigating the influence of quantum information (QI) scrambling on correlations in a physical system is an interesting problem. In this article, we establish mathematical connections among quantifiers known as scrambling, Uhlmann fidelity, Bures metric and bipartite concurrence. We study these via four-point out-of-time-order correlation function used for scrambling. Further, dynamics all in...

We systematically investigate scrambling (or delocalizing) processes of quantum information encoded in quantum many-body systems by using numerical exact diagonalization. As a measure of scrambling, we adopt the tripartite mutual information (TMI) that becomes negative when quantum information is delocalized. We clarify that scrambling is an independent property of integrability of Hamiltonians...

To mitigate privacy concerns, scrambling can be used to conceal face regions present in surveillance video content. Given that lightweight scrambling tools may not protect chroma information in order to limit bit rate overhead in heterogeneous usage environments, this paper investigates how the presence of non-scrambled chroma information in face regions influences the effectiveness of automati...

Scott syndrome is an hereditary bleeding disorder characterized by a deficiency in platelet procoagulant activity. Unlike normal blood cells, Scott platelets, as well as erythrocytes and lymphocytes, are strongly impaired in their ability to scramble their membrane phospholipids when challenged with Ca21. In normal cells this collapse of membrane asymmetry leads to surface exposure of phosphati...

A bstract In this article we discuss the impact of conservation laws, specifically U(1) charge and energy conservation, on scrambling dynamics, especially approach to late time fully scrambled state. As a model, consider d + 1 dimensional ( ≥ 2) holographic conformal field theory with Einstein gravity dual. Using dictionary, calculate out-of-time-order-correlators (OTOCs) that involve conserved...
