Motivated by recent neutron scattering and scanning tunneling microscopy ~STM! experiments on cuprate superconductors, we discuss charge-ordered states, in particular with two-dimensional charge modulation patterns, coexisting with superconductivity. We extend previous studies of a large-N mean-field formulation of the t-J model. In addition to bond-centered superconducting stripe states at low...

Over the last 10 years our understanding of the short-term memory (STM) codes and processes used by hearing children has increased dramatically. In contrast, relatively little is known about the development of these processes in deaf children. This paper explores the development of these processes. In particular the relationship between the use of STM codes and reading ability of deaf children ...

We report a combined experimental and theoretical study on the formation of dumbbell silicene structures Ag(110). High-resolution scanning tunneling microscopy (STM) reveals rich tapestry adatom-free -decorated bidimensional phases covering whole Ag(110) surface. The most thermodynamically stable models obtained from density-functional theory (DFT) perfectly reproduce all features observed by S...

This study re-explored the nature of verbal short-term memory (STM) deficits in children with specific language impairment (SLI), by distinguishing item and serial order STM processes. Recent studies have shown serial order STM capacity to be a critical determinant of language development, relative to item STM. In Experiment 1, 12 children with SLI, 12 age-matched children and 12 language-match...

Whether visual imagery and visual short-term memory (STM) share the same neural resources, and the extent to which the early visual cortex (V1/V2) is involved in these processes, has been the subject of much debate. Here, we used transcranial magnetic stimulation (TMS) in two separate experiments to contrast the neural states associated with visual imagery and visual STM in the early visual cor...

Software transactional memory (STM) is a promising paradigm for the development of concurrent software. It coordinates the potentially conflicting effects of concurrent threads on shared memory by running their critical regions isolated from each other in transactions in an “all-or-nothing” manner. When encountering a conflicting access to shared memory, a conflict resolution strategy decides w...

the main objective of an ecosystem sustainable management is to preserve itscapacity to respond and adapt to current disturbances and/or future changes, and maintain theprovision of environmental goods and services. two very important properties linked to thisobjective are the ecosystem resilience and resistance to disturbance factors. the objective ofthis paper is to recommend conceptual modif...
