In an artificial grammar learning (AGL) experiment, participants were trained with instances of one grammatical structure before completing a test phase in which they were required to discriminate grammatical from randomly created strings. Importantly, the underlying structure used to generate test strings was different from that used to generate the training strings. Despite the fact that gram...

Macroscopic fundamental and Dirichlet strings have several potential instabilities: breakage, tachyon decays, and confinement by axion domain walls. We investigate the conditions under which metastable strings can exist, and we find that such strings are present in many models. There are various possibilities, the most notable being a network of (p, q) strings. Cosmic strings give a potentially...

Cascaded multilevel inverters, such as the cascaded H-bridge (CHB) converter, are an attractive solution for multistring photovoltaic (PV) systems, because they enable direct connection to medium voltage grid and maximum power point tracking (MPPT) of multiple strings. As a challenge topology, operation with high imbalance in strings is constrained by overmodulation. This limitation analyzed si...

A bstract The vacuum manifold of the standard electroweak model is a three-sphere when one considers homogeneous Higgs field configurations. For inhomogeneous configurations we argue that Hopf fibered three sphere and this viewpoint leads to general criteria detect monopoles Z-strings. We extend Kibble mechanism study formation strings during symmetry breaking. distribution magnetic produces fi...

We consider strings with the Nambu action as extremal surfaces in a given space-time, thus, we ignore their back reaction. Especially, we look for strings sharing one symmetry with the underlying space-time. If this is a non-null symmetry, the problem of determining the motion of the string can be dimensionally reduced. We get exact solutions for the following cases: straight and circle-like st...

In two experiments, we investigated the correspondences between off-line word segmentation and on-line processing during Chinese reading. Experiment 1, participants were asked to read sentences which contained critical four-character strings, then, they required segment same into words in a later task. For each item, split 1-word segmenters (who segmented strings as single word) 2-word 2 two-ch...

Abstract We relate the low-energy expansions of world-sheet integrals in genus-one amplitudes open- and closed-string states. The respective expansion coefficients are elliptic multiple zeta values (eMZVs) open-string case non-holomorphic modular forms dubbed ‘modular graph (MGFs)’ for closed strings. By inspecting differential equations degeneration limits suitable generating series integrals,...
