PurposeA global crisis like that caused by the COVID-19 pandemic threatens the survival of any business, but especially of nascent entrepreneurs, due to their vulnerable situation. At this stage of entrepreneurship, info...

Orthogonal frequency division multiple access (OFDMA) is a multiuser communication technique that allocates to each user a set of orthogonal carriers. In the presence of carrier frequency offset (CFO) the orthogonality a...

Abstract In this paper we have presented the four new investigations using different structures of Photonic Crystal Fiber (PCF) for broadband communication applications and narrows down on the design which can provide la...

This paper proposes a dynamic error compensation method that integrates inertial measurement unit (IMU) data. The initial distance is obtained based on the binocular vision triangulation ranging principle. By analyzing t...

As the core component of the electromagnetic force compensation weight detector, the force measurement sensitivity of the integrated flexible hinge sensor directly determines the resolution of the electromagnetic force c...

INTRODUCTION: With the deepening of China's "Dual Carbon" goals, the scale of photovoltaic (PV) installations continues to expand, placing stringent requirements on the accuracy, scenario adaptability, and robustness of ...

Abstract The spherical plain bearing test bench is a necessary detecting equipment in the research process of self-lubricating spherical plain bearings. The varying environmental temperatures cause the thermal deformatio...

IntroductionCoastal wetlands provide critical ecosystem services but face increasing threats from human activities. Although ecological compensation mechanisms are globally recognized, research on tourist willingness-to-...

Thin-film-lithium-niobate (TFLN) photonics has attracted intensive attention and become very popular in recent years. Here, an ultra-compact TFLN on-chip dispersion compensator is proposed and realized to provide a promi...

Abstract Targeting the environment of gas-cooled reactors (800 °C, 1 Mpa), we propose an all-sapphire composite-cavity sensor system for pressure measurement with in-situ temperature compensation. The sensor based on ...

We present a high-speed wavelength tunable photonic crystal fiber-based source capable of generating tunable femtosecond solitons in the infrared region. Through measurements and numerical simulation, we show that...

Abstract Precision grinding is a key process for realizing the use of large-aperture aspherical optical elements in laser nuclear fusion devices, large-aperture astronomical telescopes, and high-resolution space cameras....

The deep integration of digital technology in the tourism industry has made perceived digital exclusion a significant challenge affecting the travel experiences of elderly tourists. However, the specific psychological pa...

The aim of this article is to answer the question whether the compensatory bonus is revenue or expenditure of public budgets. To answer this question, the article analyzes the legal regulation of the compensation bonus a...

Abstract The lower limb exoskeletons are used to assist wearers in various scenarios such as medical and industrial settings. Complex modeling errors of the exoskeleton in different application scenarios pose challenges ...

The paper analyses different approaches to the issue of non-pecuniary damage compensation in selected other employment relationships, focusing on service relationships. The object of the paper is in particular to point o...

Pro‑cyclical and non‑cyclical sectors generate markedly different revenue patterns, a distinction that may influence firms’ willingness to share profits with investors. This study examines whether ownership structu...

Forecasts predict we will need 790,000 pilots by 2037. This prediction means airlines will need to increase pilot levels by 267%. Finding a solution to this pilot shortage requires the aviation community to address limit...

This research paper examines ChatGPT's methodologies for addressing the untranslatability challenges posed by verbified proper nouns in English-Arabic translation. The process of denominalization, whereby proper nouns ar...

Abstract This study investigated how joint dynamics and kinematics change with increasing squat intensity in elite powerlifters performing the powerlifting-style low-bar back squat. Twenty-nine national- and internationa...

Feeding conditions during the nestling period may significantly affect whole-life fitness in altricial birds but little is known about the physiological mechanisms responsible for these effects. Permanent changes (irreve...
