We propose a description of the model of a random piecewise constant field formed by the sum of realizations of two Markov processes with an arbitrary number of states and defined along mutually perpendicular axes. The number of field quantization levels can be arbitrary. Realizations of a random field model of the desired shape are created by appropriate selection of parameters for formative realization of Markov processes. For the proposed field model, we investigated the sampling and restoration algorithm of any selected realizations. As a result, we determined the optimal sampling and recovery algorithms. The resulting sampling is fundamentally non-periodic. Recovery errors are calculated. Two examples are considered.

Few studies have comprehensively examined the reciprocal relation between specific parenting practices and children's academic performance across parent and child gender. The present study investigated the bidirectional associations between parental warmth/control and children's academic performance using a three-wave longitudinal multi-informant design. A total of 814 families (M = 10.

Objectives: To investigate whether baseline depressive symptoms impacted the effectiveness of an exercise intervention among (pre)frail older adults.

Methods: This is a subanalysis of a stepped-wedge cluster randomized trial implementing an exercise intervention, with an application of the integration of the Health Belief Model, Theory of Planned Behavior, and Health Action Process Approach, among 149 community-dwelling (pre)frail older adults. The intervention effectiveness was examined by baseline depressive symptoms (depressive symptoms ( = 40) and non-depressive symptoms ( = 109).

Context: The use of prebiotics and probiotics as a treatment for psychiatric conditions has gained interest due to their potential to modulate the gut-brain axis. This review aims to assess the effectiveness of these interventions in reducing symptoms of depression and anxiety in psychiatric populations.

Objective: The aim was to comprehensively review and appraise the effectiveness of prebiotic, probiotic, and synbiotic interventions in reducing clinical depression and anxiety symptoms.

Objectives: To investigate maxillary canine movement accuracy and anchorage during space closure in first premolar extraction cases (maximum anchorage) using In-House Clear Aligners (IHCAs).

Materials And Methods: A randomised controlled trial with a split-mouth design recruited 16 adults in university setting. Each patient was randomly assigned by side for canine retraction using 12 IHCAs to both the experimental palatal power arm (Pa) and non-Pa control (C).

Background: Interpersonal outcomes and mental health problems are closely associated. However, their reciprocal influence has not been directly examined while considering the temporal stability of these constructs, as well as shared and unique variance associated with internalising, externalising and attention problems. Using random intercept cross-lagged panel models (RI-CLPM), we tested the hypotheses that negative bidirectional associations at the between-person and negative cross-lagged effects at the within-person level would emerge between interpersonal outcomes (friendship quality and perceived popularity) and mental health problems (i.
