The road from MLE to EM to VAE: A brief tutorial
Variational Auto-Encoders (VAEs) have emerged as one of the most popular genres of generative models, which are learned to characterize the data distribution. The classic Expectation Maximization (EM) algorithm aims to learn models with hidden variables. Essentially, both of them are iteratively…

Glutamate transmission in the prelimbic cortex and nucleus accumbens shell is involved in ethanol reinforcement and drinking in rats
IntroductionResearch has implicated mesocorticolimbic glutamate transmission in alcohol use. The current study focused on glutamate transmission within two key sub-regions, i.e., prelimbic (PL) cortex and nucleus accumbens (NAc) shell, in mediating ethanol reinforcement and drinking in…

Determination of cyanide in bamboo shoots by microdiffusion combined with ion chromatography–pulsed amperometric detection
A practical method for the determination of cyanide in bamboo shoots has been developed using microdiffusion preparation integrated with ion chromatography–pulsed amperometric detection (IC-PAD). Cyanide was released from bamboo shoots after Conway cell microdiffusion, and then analysed by IC-PAD…

3-D microarchitectural properties and rod- and plate-like trabecular morphometric properties of femur head cancellous bones in patients with rheumatoid arthritis, osteoarthritis, and osteoporosis
Objectives: We quantify 3-D microarchitectural properties of femoral head cancellous bones from patients with rheumatoid arthritis (RA, n = 12), osteoarthritis (OA, n = 15), osteoporosis (OP, n = 24), or donor controls (CNT, n = 8); and investigate their rod- and plate-like trabecular morphometric…

Astrocytes in the Ventral Tegmental Area Are Involved in Cotinine Self-Administration in Male Wistar Rats
Background: Our recent studies indicate that astrocytes in a key mesocorticolimbic region play an important role in nicotine reinforcement. Nicotine self-administration elevated the astrocyte marker glial fibrillary acidic protein (GFAP) in the nucleus accumbens (NAc) core. Metabolic inhibition of…

A Review of Lipidomics of Cardiovascular Disease Highlights the Importance of Isolating Lipoproteins
Cutting-edge lipidomic profiling measures hundreds or even thousands of lipids in plasma and is increasingly used to investigate mechanisms of cardiovascular disease (CVD). In this review, we introduce lipidomic techniques, describe distributions of lipids across lipoproteins, and summarize…

Combined analysis on nature of X(3960), $$\chi _{c0}(3930)$$ χ c 0 ( 3930 ) , and $$X_0(4140)$$ X 0 ( 4140 )
Abstract In this work, a study of the $$D_s{\bar{D}}_s$$ D s D ¯ s interaction and its couplings to the channels $$D{\bar{D}}$$ D D ¯ and $$J/\psi \phi $$ J / ψ ϕ is performed in a quasipotential Bethe–Salpeter equation approach. The $$D_s^+{D}_s^-$$ D s + D s - and $$D^+{D}^-$$ D + D - invariant…

The properties on F-manifold color algebras and pre-F-manifold color algebras
The concept of F-manifold algebras is an algebraic expression of F-manifolds. In this paper, we provide the definition of an F-manifold color algebra, which can be viewed as a natural generalization of an F-manifold algebra. We develop the representation theory of an F-manifold color algebra and…

Orifice plate cavitation mechanism and its influencing factors
The orifice plate energy dissipater is an economic and highly efficient dissipater. However, there is a risk of cavitaion around the orifice plate flow. In order to provide references for engineering practice, we examined the cavitation mechanism around the orifice plate and its influencing factors…

Three-dimensional morphometric properties of rod- and plate-like trabeculae in adolescent cancellous bone
Background/Objective: Despite many researches have been carried out on the three-dimensional microarchitecture of cancellous bone, the morphometric properties of rod and plate trabeculae in adolescent cancellous bone have not yet been investigated. This study aimed to investigate three-dimensional…

Deep Q-Learning for Two-Hop Communications of Drone Base Stations
In this paper, we address the application of the flying Drone Base Stations (DBS) in order to improve the network performance. Given the high degrees of freedom of a DBS, it can change its position and adapt its trajectory according to the users movements and the target environment. A two-hop…

Flying Drone Base Stations for Macro Hotspots
We study a scenario where multiple drone-mounted base stations cruise freely over a macro hotspot to serve mobile users on the ground. The drone base stations move constantly and update their moving directions following our proposed mobility control algorithm. The constant movement of drones…

Multiple Spatiotemporal Characteristics-Based Zonal Voltage Control for High Penetrated PVs in Active Distribution Networks
The penetration of photovoltaic (PV) outputs brings great challenges to optimal operation of active distribution networks (ADNs), especially leading to more serious overvoltage problems. This study proposes a zonal voltage control scheme based on multiple spatiotemporal characteristics for highly…

Temperature Sensor Based on Microbottle Resonator Immersed in Isopropanol
Temperature measurement of an isopropanol-immersed microbottle resonator is demonstrated. The theoretical analysis indicates that the resonance wavelength blue shifts as the increase of temperature, and the temperature sensitivity increases with the decrease of resonator dimension, which are also…

Parameter Resolution of the Estimation Methods for Power Law Indices
The accuracy of parameter estimation plays an important role in economic and social models and experiments. Parameter resolution is the capability of an estimation algorithm to distinguish different parameters effectively under given noise level, which can be used to select appropriate algorithm…

Therapeutic progress in leptomeningeal metastasis from EGFR mutant non-small cell lung cancer: a clinical medicine review
Abstract Leptomeningeal metastasis in patients with Epidermal Growth Factor Receptor-mutant non-small cell lung cancer carries a dismal prognosis and is associated with profound neurological morbidity. Historically, therapeutic efficacy has been severely limited, leading to poor overall survival…
