Which Symptoms of Nomophobia, Social Networking Site Addiction, and Fear of Missing Out (FoMO) Directly Affect Mental Health? A Symptom Network and Flow Analysis Study

open access: yesPsyCh Journal, EarlyView.
ABSTRACT Nomophobia, social networking site (SNS) addiction, and fear of missing out (FoMO) are increasingly recognized as interrelated digital‐age phenomena that pose risks to young people's mental health. However, limited research has examined how specific symptoms across these domains interact and contribute to anxiety and depression.

What Is a Polyolefin? A Critical Overview of Ethylene Copolymers Used as Solar Photovoltaic Module Encapsulants

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Polyolefin encapsulants are gaining dominance in PV modules, yet confusion persists around PO, POE, and TPO definitions. This study clarifies terminology, reviews materials, and properties and proposes a taxonomy to improve understanding, communication, and reliability in solar module manufacturing.

Injection Locking of Gigahertz‐Frequency Surface Acoustic Wave Phononic Crystal Oscillator

open access: yesphysica status solidi (a), EarlyView.
The compact surface‐acoustic‐wave phononic‐crystal oscillator is stabilized by injection locking it to an ultra‐stable reference. The injection locking suppresses the phase noise by 40 dB at low offset frequency region and reduces long‐term frequency drift from hundreds of hertz to 0.35 Hz, advancing portable, high‐performance timing and signal ...

Substrate‐Versatile and Stress‐Free Tellurization of PtTe2 Films

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
A two‐step (platinum deposition followed by tellurization) scalable process that can be easily combined with lithographic techniques is developed for the growth of PtTe2 films. By optimizing a slower tellurization thermal ramp, stress‐free PtTe2 growth both on silicon and dielectric substrates is achieved, proving substrate versatility.

High‐Precision Measurement of Time Delay with Frequency‐Resolved Hong‐Ou‐Mandel Interference of Weak Coherent States

open access: yesAdvanced Quantum Technologies, EarlyView.
High‐precision time‐delay measurements are demonstrated using frequency‐resolved Hong‐Ou Mandel (HOM) interference with weak coherent states. The method, by exploiting the quantum eraser phenomenon, achieves low uncertainty even for delays exceeding the photon coherence time, where traditional HOM interferometry fails, thus confirming theoretical ...

IDLB: An SDN‐Based Load‐Balancing Routing Protocol for Autonomous Satellite Constellation Networks

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Routing in satellite constellation networks with intersatellite links has become an important aspect to enable broadband Internet access and to integrate into terrestrial networks. However, their dynamic characteristics and large physical size require specifically tailored solutions.

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

Advanced Fade Mitigation Techniques for Q/V Band SATCOM Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Adaptive fade mitigation techniques, such as smart gateway diversity (SGD), are essential in addressing atmospheric fading affecting the operation of high throughput and very high throughput satellite systems at Ka‐band and beyond. Specifically, the Q/V‐band, offering up to 5 GHz of available spectrum, is very attractive for future high data ...
