This paper presents an interval-based positional logic and proves its completeness. The proposed logic combines positional operators, deened by time intervals, with modal operators used to express the subinterval relationship. Moreover, the logic can be easily extended either by including more predicates for absolute temporal references or by adding other operators for relative and periodical t...

UNLABELLED The effects of Epley's maneuver in benign paroxysmal positional vertigo (BPPV) associated with Menière's disease are controversial. AIMS To evaluate the progression of positional vertigo and nystagmus after one or more of Epley's maneuvers in BPPV associated with Menière's disease, and the recurrence of BPPV. METHOD a retrospective study of 62 patients with BPPV associated with M...

BACKGROUND Cell position rather than cell lineage governs most aspects of development in plants. However, the nature and the origin of positional information remains elusive. Animal epidermal patterning relies in many cases on positional information provided by cell-cell communication. The epidermal layer of the Arabidopsis root is made of alternating files of two cell types and thus presents a...

Uncertainty quantification is not often performed in spatial analysis and modeling applications. One reason is the lack of tools which can handle various kinds of uncertainty associated with spatial data. In particular, positional uncertainty in objects is often ignored. There has been much research in regards to the modeling of different kinds of positional uncertainty (e.g., measurement error...

Is there a positive association between a nation's income inequality and concerns with status competition within that nation? Here we use Google Correlate and Google Trends to examine frequency of internet search terms and find that people in countries in which income inequality is high search relatively more frequently for positional brand names such as Prada, Louis Vuitton, or Chanel. This te...

Access to well-structured and sometimes self-describing spatial position data with associated data attributes in geographical scales domains is increasing, and is expected to increase further. Until recently, it has often been sufficient to treat data sets as autonomous, dropping positional metadata attributes for analysis and visualization. It may be argued that this is short-sighted, because ...

This paper studies structural aspects concerning optimal positional strategies in Mean Payoff Games, it is a contribution to understanding the relationship between optimal positional strategies in MPGs and small energy-progress measures in reweighted energy games. It is proved an energy decomposition theorem describing the whole space of all optimal positional strategies in terms of so-called e...

AIM We aimed to prove the existence of positional effects in the Illumina methylation beadchip data and to find an optimal correction method. MATERIALS & METHODS Three HumanMethylation450, three HumanMethylation27 datasets and two EPIC datasets were analyzed. ComBat, linear regression, functional normalization and single-sample Noob were used for minimizing positional effects. The corrected r...

in the present paper, we introduce the sequence space [{l_p}(e,delta) = left{ x = (x_n)_{n = 1}^infty : sum_{n = 1}^infty left|  sum_{j in {e_n}} x_j - sum_{j in e_{n + 1}} x_jright| ^p < infty right},] where $e=(e_n)$ is a partition of finite subsets of the positive integers and $pge 1$. we investigate its topological properties and inclusion relations. moreover, we consider the problem of fin...

Tendons can be considered in two functional groups, those contributing to energetics of locomotion and those acting solely to position the limb. The energy-storing tendons in both human and equine athletes have a high frequency of injury with similar pathophysiology. In previous studies, high-intensity exercise appears to induce a disruption of the matrix rather than functional adaptation in ad...
