Directionality in time series and its applications
A suite of seven statistics to detect directionality in time series is presented. Applications from various disciplines including business, environmental science, finance and medicine are considered. Models that allow for directionality are proposed, and methods of fitting these models are …

(Negative) concord and head directionality in Western Armenian
… bring about some issues regarding head directionality. Western Armenian is a generally head-final language. Certain domains exhibit both head-initial and head-final possible structures. These are found in the complementizers and the adpositions of the language. The complementizer phrases …

Effect of Occlusion, Directionality and Age on Horizontal Localization
<p>Localization acuity of a given listener is dependent upon the ability discriminate between interaural time and level disparities. Interaural time differences are encoded by low frequency information whereas interaural level differences are encoded by high frequency information. Much research has …

A Descriptive Study of Lateral Dominance and Directionality in Kindergarten Children
… the relationship between lateral dominance and directionality, (2) determine the relationship lateral dominance and directionality have with age and intelligence quotient, and (3) gather evidence on the differences between boys and girls in the development of lateral dominance and directionality.

The Impact of Translation Directionality on the Translation of Emotional Words
Τις τελευταίες τρεις δεκαετίες, η γνωστική πλευρά της μετάφρασης έχει προσελκύσει το ενδιαφέρον των μεταφρασεολόγων, με πρόσφατες έρευνες να στρέφονται προς τη μελέτη του «συναισθηματικού εγκεφάλου» και τη σχέση μεταξύ συναισθημάτων και μετάφρασης (Rojo López & Muñoz, 2022). Στο πλαίσιο αυτό, …

Utopian Hope vs. Merely-Political Combat: Directionality for the Kingdom of God
Utopia, as a concept, has experienced a resurgence within literature of various genres, ranging from scholarly work inside the 'academy' to diverse accounts of utopian and/or dystopian imaginaries within diverse fictional stories. Identifying what utopia picks out conceptually, however, is …

The effects of working memory and directionality on sentence build-up drill performance
This study investigated the role of working memory (WM) and input direction in the use of sentence build-up drills (SBD). Thirty Chinese L2 speakers participated in the experiment, which consisted of a SBD test, a R-span test, and a language background questionnaire. The results indicate that the …

Measurements of the horizontal directionality of the ambient acoustic noise in Monterey Bay, California
Measurements of some of the horizontal characteristics of acoustic ambient noise were carried out in the south-eastern parts of Monterey Bay, California, at a limited number of stations and for a limited number of ambient conditions. Directional hydrophones on buoys located at ranges of two to four …

Promoter directionality is controlled by U1 snRNP and polyadenylation signals in mouse embryonic stem cells
… indicate that the mechanism regulating promoter directionality at divergent promoters occurs after PTEFb recruitment. In Chapter 3, we describe a genome-wide analysis to map the 3'-ends of polyadenylated RNAs in mESCs and reveal that uaRNAs terminate through a poly (A) site (PAS)-dependent …

An Application of Wavelet Techniques to Bi-directionality in the Monte Carlo Ray Trace Environment
… three different aspects of the incorporation of directionality into the Monte Carlo ray-trace (MCRT) environment: (1) the development of a methodology for using directional surface optical data, (2) the measurement of the bi-directional reflectivity functions for two different surfaces, and (3) …

A parameters approach to second language research: Testing a directionality prediction of the null subject parameter
This study applies insights from present linguistic theory (Chomsky 1981, 1986) to predict what the influence of the first language (L1) is on the acquisition of linguistic competence in a second language (L2). Present linguistic theory claims that differences in languages can be captured by a …

Cholinergic Regulation of Circadian Rhythms in the SCN: Characterization of Signaling Mechanisms and the Role of Intracellular Calcium in the Directionality of Clock Resetting
This study shows that stimulus-specific intracellular Ca2+ (Ca2+i) release controls the direction of clock resetting. Direct activation of the InsP3-induced Ca2+ i release (IICR) mimics cholinergic phase advance, while InsP3 , but not ryanodine, receptor antagonists block it. In contrast, selective …

Target tracking onboard an autonomous underwater vehicle : determining optimal towed array heading in an anisotropic noise field
… an onboard estimation of the horizontal noise directionality in the real-time processing suite of an autonomous underwater vehicle (AUV) towing a horizontal line array. The estimation of the noise directionality is a precursor to another adaptive behavior: optimizing tracking capability of a …

Towards a Temporal Theory of Ecology: Body Mass Role for Activity Patterns of North American Artiodactyls
… were classified as homogenous (i.e., low directionality with activity distributed along a 24-hour period), or heterogenous (i.e., high directionality with peaks of activity at different times of the 24-hour period). We found that as the strength of intraspecific diel temporal niche …

Does Motion Parallax Improve Communication Efficiency in Video Chats?
… distances and orientations of the objects. Directionality is a mutual understanding of the distance and orientation of people in 3D space (Troje, 2023). Previous studies have found that motion parallax is important in determining the direction of objects (Wang & Troje, 2023). Motion parallax …

Understanding the mechanism of injury associated with long bone fractures through dynamic bending impact
… butterfly fracture aids in the establishment of directionality of the force applied. Currently, forensic anthropologists employ a method dictating that the base of the butterfly fragment pertains to the side of impact, while the apex of the fragment pertains to the opposite side of impact. Recent …

Characterization of flow control using programmable multi-directional plasma actuators
… which are reliant on geometry to define flow directionality. This thesis defines and makes use of a new class of plasma actuator which can generate directionally differentiated flows within a single geometry via use of high voltage switches and specialized geometries. The multidirectional …

Optimizing Urban Air Mobility Operations in a Corridor Network
… between origin and destination, as well as flow directionality in corridors. We formulate an integer optimization model in a time-space-network that exploits a subpath structure at the flight level. We propose a column generation algorithm to decompose vehicle dispatching decisions in a master …

About Time... (Some Patterns of Time -Reckoning)
… and, hence, different patterns of temporal directionality. These patterns are context specific. By contrast, temporal rhythms occur in different contexts and may have universal features that may allow for an anthropological discussion of time that is primarily a discussion of time as opposed …
