Galerkin Finite Element Based Modeling of One Dimensional Packed Bed Reactor for Underground Coal Gasification (UCG) Process
(IEEE, 20201211)Mathematical models of a complex physicochemical underground coal gasification process involve multidimensional nonlinear partial differential equations (PDEs). Therefore, researchers always seek a suitable numerical ... 
Game play in virtual reality driving simulation involving headmounted display and comparison to desktop display
(Springer, 20191128)Previous studies have reported the effect of driving simulator games on simulator sickness and eye symptoms experienced by users; however, empirical results regarding the game experience using commercial virtual reality ... 
Gamification and Gaming in Cryptocurrency Education: Perspectives of Cryptocurrency Investors and Potential Investors
(Sage, 20240122)Introduction: In recent years, cryptocurrency has increasingly sparked interest among investors. Many people have invested in this field without adequate knowledge. Existing research has shown that using game design elements ... 
The Gamification User Types Hexad Scale
(ACM, 20161016)Several studies have indicated the need for personalizing gamified systems to users' personalities. However, mapping user personality onto design elements is difficult. Hexad is a gamification user types model that attempts ... 
Gaps in the Evidence on Population Interventions to Reduce Consumption of Sugars: A Review of Reviews
(MDPI, 20180808)There is currently considerable attention directed to identifying promising interventions to reduce consumption of sugars among populations around the world. A review of systematic reviews was conducted to identify gaps ... 
Garnet fractionation, progressive melt loss and bulk composition variations in anatectic metabasites: Complications for interpreting the geodynamic significance of TTGs
(Elsevier, 202005)Tonalitetrondhjemitegranodiorite (TTG) suites constitute a large proportion of the Archean geological record; however, the geodynamic processes that generated them, and Archean continental crust in general, remain a ... 
Gaussian Laws on Drinfeld Modules
(World Scientific, 2009)Let A = 𝔽q[T] be the polynomial ring over the finite field 𝔽q, k = 𝔽q(T) the rational function field, and K a finite extension of k. Let ϕ be a Drinfeld Amodule over K of rank r. For a place 𝔓 of K of good reduction, ... 
The Gaze Cueing Effect and Its Enhancement by Facial Expressions Are Impacted by Task Demands: Direct Comparison of Target Localization and Discrimination Tasks
(Frontiers, 20210311)The gaze cueing effect is characterized by faster attentional orienting to a gazedat than a nongazedat target. This effect is often enhanced when the gazing face bears an emotional expression, though this finding is ... 
Gearbox Fault Detection using Synchrosqueezing Transform
(Elsevier, 2016)This paper presents a novel faultdetection method for gearbox vibration signatures using synchrosqueezing transform (SST). Premised upon the concept of timefrequency (TF) reassignment, SST provides a sharp representation ... 
A genderstratified, multilevel latent class assessment of chronic disease risk behaviours' association with Body Mass Index among youth in the COMPASS study
(Elsevier, 201909)This paper sought to examine chronic disease risk behaviour latent classes and their association with Body Mass Index (BMI), assessing for gender differences. Participants were youth (n = 116,086; grades 9–12) enrolled in ... 
A generalization of Meshulam's theorem on subsets of finite abelian groups with no 3term arithmetic progression
(Springer, 20090131)Let r1, . . . , rs be nonzero integers satisfying r1 + · · · + rs = 0. Let G Z/k1Z⊕· · ·⊕Z/knZ be a finite abelian group with ki ki−1(2 ≤ i ≤ n), and suppose that (ri , k1) = 1(1 ≤ i ≤ s). Let Dr(G) denote the maximal ... 
A generalization of Meshulam's theorem on subsets of finite abelian groups with no 3term arithmetic progression (II)
(Elsevier, 201102)Let G ≃ Z/k1Z ⊕ · · · ⊕ Z/kN Z be a finite abelian group with ki ki−1 (2 ≤ i ≤ N). For a matrix Y = (ai,j) ∈ Z R×S satisfying ai,1 + · · · + ai,S = 0 (1 ≤ i ≤ R), let DY (G) denote the maximal cardinality of a set ... 
A Generalization of Roth's Theorem in Function Fields
(University of Michigan, Department of Mathematics, 201211)For n ∈ N = {1, 2, ...}, let D3([1, n]) denote the maximal cardinality of an integer subset of [1, n] containing no nontrivial 3term arithmetic progression. In a fundamental paper [9], Roth proved that D3([1, n]) n/log ... 
A generalization of Roth's theorem in function fields
(World Scientific Publishing, 200911)Let 𝔽q[t] denote the polynomial ring over the finite field 𝔽q, and let formula denote the subset of 𝔽q[t] containing all polynomials of degree strictly less than N. For nonzero elements r1, …, rs of 𝔽q satisfying r1 ... 
A Generalization of the ErdösKac Theorem and its Applications
(Cambridge University Press, 20041201)We axiomatize the main properties of the classical ErdösKac Theorem in order to apply it to a general context. We provide applications in the cases of number fields, function fields, and geometrically irreducible varieties ...

Genesis of a giant Paleoproterozoic stratabound magnesite deposit: Constraints from Mg isotopes
(Elsevier, 20160801)Giant stratabound magnesite deposits are absent in modern and most Phanerozoic sedimentary environments but occur predominantly in Precambrian strata. These deposits may have formed directly through precipitation of evolved ... 
GeoPhisher: The Design and Evaluation of Information Visualizations about Internet Phishing Trends
