Generation of terahertz vector beams using dielectric metasurfaces via spin-decoupled phase control
Abstract Cylindrical vector beams (CVBs), being a special kind of beams with spatially variant states of polarizations, are promising in photonics applications, including...

The paper examines the fusion of narratives, time, space, and personal identity through ethnographic study of rickshaw driver’s performance in the context of “Hutong tour” as a form of urban tourism in Beijing, a cosmopolitan...
A Historical Review on Learning With Technology
Zhi Quan, Yueyi Zhang
Jul 01, 2024
Among the terms for technology-enhanced education, ‘e-learning' may be an umbrella one to cover various types; on the mobile platform, ‘mobile learning' or ‘m-learning' has gained a solid foothold. A historical review of the...
Tracking differentiator based back-stepping control for valve-controlled hydraulic actuator system

Back-stepping design method is widely used in high-performance tracking control tasks As is known to all, the controller based on back-stepping design will become complex as the model order increases, which is the so called...

Cyclic adenosine 5′-diphosphate ribose analogs without a southern ribose inhibit ADP-ribosyl cyclase-hydrolase CD38

Cyclic adenosine 5′-diphosphate ribose (cADPR) analogs based on the cyclic inosine 5′-diphosphate ribose (cIDPR) template were synthesized by recently developed stereo- and regioselective N1-ribosylation. Replacing the base...

Identification of high risk clinical and imaging features for intracranial artery dissection using high-resolution cardiovascular magnetic resonance
Abstract: Background: Intracranial artery dissection (IAD) often causes headache and cerebral vascular ischemic events. The imaging characteristics of IAD remain unclear. This study aims to characterize the appearance of culprit...

First birth following spindle transfer for mitochondrial replacement therapy
In this issue, Zhang et al. (2017) report the birth of a healthy boy after mitochondrial replacement therapy (MRT) by spindle transfer to prevent transmission of mitochondrial disease from mother to child. The case was first...
Development and Application of Interactive Teaching Systems for Online Design Courses
Digital education has recently become a mainstream education model. Despite digital education's increasing popularity, there remain issues when it comes to teacher-student interactions in digital space, which have made it...
Deconstructing Online Hospitality Review Systems
Online hospitality reviews have an important impact on consumers’ travel and hospitality booking decisions in the Internet age. A well-designed online hospitality review system is crucial to reduce the uncertainty of consumers’...
Sterics and Hydrogen Bonding Control Stereochemistry and Self-Sorting in BINOL-Based Assemblies.
Here we demonstrate how the hydrogen-bonding ability of a BINOL-based dialdehyde subcomponent dictated the stereochemical outcome of its subsequent self-assembly into one diastereomeric helicate form when bearing free hydroxy...
System Dynamics Modeling Of Socioeconomic Development Mode Associated With Water Usage In Baiyangdian Lake, Northern China
With continual increase of environmental pressure from human activities, it has become necessary to study the process of socioeconomic water usage influencing the water quality. Based on the system dynamic model developed before...
Dynamic pricing for responsive demand to increase distribution network efficiency

This paper designs a novel dynamic tariff scheme for demand response (DR) by considering networks costs through balancing the trade-off between network investment costs and congestion costs. The objective is to actively...
