Regulation of Feeding Behavior and Body Weight by Orexigenic Neurons in the Arcuate Nucleus
The arcuate nucleus of the hypothalamus is arguably the most important nucleus for regulating energy homeostasis and metabolism. Since its initial description in the human brain, its function in metabolic regulation has been studied extensively. Key neuronal populations such as agouti-related…

Biharmonic and Quasi-Biharmonic Slant Surfaces in Lorentzian Complex Space Forms
In 1991, Chen and Ishikawa initially studied biharmonic marginally trapped surfaces in neutral pseudo-Euclidean 4-space. Recently, biharmonic and quasi-biharmonic marginally trapped Lagrangian surfaces in Lorentzian complex space forms were studied by Sasahara in 2007 and 2011, respectively. In…

S-index periodicity detection based on multiple random spectral observations
Abstract The solar magnetic activity cycle has a profound impact on our lives, yet its underlying causes remain elusive. While similar cycles have been observed in other stars, these results are scarce due to the significant challenge posed by the length of time required for observation. Continuous…

Wanwuyiti and Finding God in All Things: A Comparative Study between Neo-Confucian Self-Cultivation and Ignatian Spirituality
It seems that the early Jesuits misinterpreted the key Neo-Confucian terms taiji/li from an Aristotelian perspective in the seventeenth century, thereby leading to a dialogical failure in their initial encounter with Neo-Confucian tradition. What necessitates interreligious dialogue today is a…

Identification of Pathogenetic Brain Regions via Neuroimaging Data for Diagnosis of Autism Spectrum Disorders
Autism spectrum disorder (ASD) is a kind of neurodevelopmental disorder that often occurs in children and has a hidden onset. Patients usually have lagged development of communication ability and social behavior and thus suffer an unhealthy physical and mental state. Evidence has indicated that…

Association between provincial sunshine duration and mortality rates in China: Panel data study
Background: mortality rates are usually influenced by the variations of environmental factors. However, there are few studies on the impact of sunlight duration induced mortality. In this study, we examine provincial level associations between the sunshine duration and crude mortality rates…

Impacts of land use and land cover changes on biogenic emissions of volatile organic compounds in China from the late 1980s to the mid-2000s: implications for tropospheric ozone and secondary organic aerosol
Based on the MEGAN (Model of Emissions of Gases and Aerosols from Nature) module embedded within the global chemical transport model (GEOS-Chem), we estimate the changes in emissions of biogenic volatile organic compounds (BVOCs) and their impacts on surface-layer O3 and secondary organic aerosols…

A cartographic analysis of Shi and Lian…Dou in Mandarin Chinese
Shi and lian … dou/ye can both be used as focus constructions in Mandarin Chinese. The current paper aims to investigate the shi and lian … dou/ye constructions within the framework of Syntactic Cartography. The two constructions share very similar syntactic distributions; however, shi and lian are…

Two centuries of large U.S. metropolitan evolution challenge the classical urban life cycle theory
Abstract The urban life cycle (ULC) theory, originally developed in European urban studies, divides urban spatial evolution into four sequential stages: urbanization, suburbanization, de-urbanization, and re-urbanization. Yet its long-term dynamics outside Europe remain insufficiently examined…

Some Characterizations of the Cobb-Douglas and CES Production Functions in Microeconomics
It is well known that the study of the shape and the properties of the production possibility frontier is a subject of great interest in economic analysis. Vîlcu (Vîlcu, 2011) proved that the generalized Cobb-Douglas production function has constant return to scale if and only if the corresponding…

Bounded Rationality of Generalized Abstract Fuzzy Economies
By using a nonlinear scalarization technique, the bounded rationality model M for generalized abstract fuzzy economies in finite continuous spaces is established. Furthermore, by using the model M, some new theorems for structural stability and robustness to (λ,ϵ)-equilibria of generalized abstract…

A Class of Weingarten Surfaces in Euclidean 3-Space
The class of biconservative surfaces in Euclidean 3-space 𝔼3 are defined in (Caddeo et al., 2012) by the equation A(grad H)=-H grad H for the mean curvature function H and the Weingarten operator A. In this paper, we consider the more general case that surfaces in 𝔼3 satisfying A(grad H)=kH grad H…

Integral Nonsingular Terminal Sliding Mode Control of Hydraulic Servo Actuator Based on Extended State Observer
Hydraulic servo actuator always suffers from various disturbance and uncertainties, which makes it difficult to design a higher performance controller. In this paper, an integral nonsingular terminal sliding mode controller based on extended state observer (ESO-INTSM) is proposed to improve the…

Improving Log-Likelihood Ratio Estimation with Bi-Gaussian Approximation under Multiuser Interference Scenarios
Accurate estimation of channel log-likelihood ratio (LLR) is crucial to the decoding of modern channel codes like turbo, low-density parity-check (LDPC), and polar codes. Under an additive white Gaussian noise (AWGN) channel, the calculation of LLR is relatively straightforward since the…
