Improving the Solution of Least Squares Support Vector Machines with Application to a Blast Furnace System by Ling Jian, Shuqian Shen, Yunquan Song

“…The solution of least squares support vector machines (LS-SVMs) is characterized by a specific linear system, that is, a saddle point system. Approaches for its numerical solutions such as conjugate methods Sykens and Vandewalle (1999) and null space methods Chu et al. (2005) have been proposed. …”

Prognostic significance of the QuickSIN score for future hearing threshold deterioration by Jiayue Liu, Haotian Zou, Eleanor M. Simonsick, Joshua Stohl, Tobias Overath

“…This study aimed to determine whether hearing difficulties in noise, as measured by the Quick Speech in Noise (QuickSIN) test, could be used to identify people at risk of the development and the progression of clinical hearing loss, using a large dataset of 1128 individuals in the Baltimore Longitudinal Study of Aging (BLSA). A linear mixed model analysis revealed that individuals with a poorer QuickSIN score at the preceding audiological assessment were likely to reveal a more substantial deterioration in clinical audiometric thresholds at their subsequent visit than those with a better QuickSIN score at their previous assessment. …”

Integrals of subharmonic functions and their differences with weight over small sets on a ray by B.N. Khabibullin

“…An integral of the maximum on circles centered at zero of $U^+:=\sup\{0,U\} $ or $|u|$ over $E$ with a function-multiplier $g\in L^p(E) $ in the integrand is estimated, respectively, in terms of the characteristic function $T_U$ of $U$ or the maximum of $u$ on circles centered at zero, and also in terms of the linear Lebesgue measure of $E$ and the $ L^p$-norm of $g$. …”

Krylov complexity in the Schrödinger field theory by Peng-Zhang He, Hai-Qing Zhang

“…Both {a n } and {b n } show linear relationships with respect to n. For both bosonic and fermionic systems, the Krylov complexities behave similarly over time, especially at late times, due to the analogous profiles of the squared absolute values of their autocorrelation functions |φ 0(t)|2. …”

Diminishing returns of task-oriented interaction in digitally-mediated dynamic teams: evidence from amateur sports organizing by Jing Yang, Tang Yao, Jun Wang

“…Although extant research has emphasized task-oriented processes in teams, its focus on dynamic teams in digital environments remains limited, particularly regarding non-linear effects. Integrating attention capacity theory and activation theory, this study proposes a curvilinear (inverted-U) relationship between task-oriented interaction and team organizing efficiency in digitally-mediated teams. …”

Spatial and Temporal Trends in the Timing of Budburst for Australian Wine Regions by C. Liles, D. C. Verdon-Kidd

“…We show that the modelled budburst date has been gradually shifting to earlier in the year for most (95%) Australian wine regions, at an average rate of one day every 24 years. This linear trend in budburst timing is likely to be associated with steadily increasing air temperatures due to anthropogenic climate change. …”

A New Method for Setting Futures Portfolios’ Maintenance Margins: Evidence from Chinese Commodity Futures Markets by Chi Xie, Jiao-Jiao Yang, Gang-Jin Wang

“…We also compare the outcomes of the two evaluation indicators of the new method with those of the widely used linear additive model. The empirical results show that the new method can, respectively, lower the OCI value of all four kinds of futures portfolios for the In-sample period and the Out-of-sample period without significantly reducing the PI value as against the traditional model, which implies that the proposed method can be used to balance security and investment efficiency in the futures market.…”
