Pinching-Antenna Systems (PASS)-based Indoor Positioning
Pinching antenna (PA), a flexible waveguide integrated with dielectric particles, intelligently reconstructs line-of-sight channels. Utilizing its geometric deterministic model and meter-level reconstruction, PA systems (PASS) are applied to uplink indoor positioning. In this paper, the uplink positioning system model for PASS is firstly proposed. A PASS-based received signal strength indication (RSSI) method is proposed to measure the distance from the users to each PA, which is efficient and …

Pinching-Antenna Systems (PASS): A Tutorial
Pinching antenna systems (PASS) present a breakthrough among the flexible-antenna technologies, and distinguish themselves by facilitating large-scale antenna reconfiguration, line-of-sight creation, scalable implementation, and near-field benefits, thus bringing wireless communications from the last mile to the last meter. A comprehensive tutorial is presented in this paper. First, the fundamentals of PASS are discussed, including PASS signal models, hardware models, power radiation models, an…

A Compact Symmetric Object Discovered by the VLA Low-band Ionosphere and Transient Experiment
We present new Very Long Baseline Array (VLBA) imaging of a MHz-peaked spectrum (MPS) source that was found using commensal low-frequency data taken with the Karl G. Jansky Very Large Array (VLA). The source, J0330-2730, was identified in multi-epoch data from the VLA Low-band Ionosphere and Transient Experiment (VLITE). VLITE continuously collects low-frequency data at 340 MHz during regular VLA observations. Our analysis of the VLITE light curve demonstrates that J0330-2730 has significant 34…

Pinching Antenna System (PASS) Enhanced Covert Communications: Against Warden via Sensing
A sensing-aided covert communication network empowered by pinching antenna systems (PASS) is proposed in this work. Unlike conventional fixed-position MIMO arrays, PASS dynamically reconfigures its pinching antennas (PAs) closer to the legitimate user, substantially enhancing covertness. To further secure the adversary's channel state information (CSI), a sensing function is leveraged to track the malicious warden's movements. In particular, this paper first proposes an extended Kalman filter (…

Der Klimawandel lässt die Gletscher schmelzen. Dadurch gibt es weniger Wasser in Bächen und Flüssen. Die Gletscher verlieren weltweit viel Eis. In Grönland und der Antarktis schmilzt das Eis schneller als früher. Das führt zu steigendem Meeresspiegel. Was bedeutet das für Menschen in Küstenregionen?

Der Klimawandel schrumpft die Gletscher. Wassermangel in den Bächen und Flüssen. (vereinfachte Sprache)
Das Abschmelzen der Gletscher ist ein Kippelement des Klimasystems. Es führt zu einem Anstieg des Meeresspiegels und hat weitreichende Folgen für die Menschheit.

Reducing AoI and Improving Throughput for NOMA-assisted SGF Systems: A Hierarchical Learning Approach
A non-orthogonal multiple access (NOMA) assisted semi-grant-free (SGF) framework is proposed to enable channel access for grant-free users (GFUs) by using residual resources from grant-based users. Under this framework, the problem of joint beamforming design and transmission scheduling is formulated to improve the system throughput and reduce the age-of-information of GFUs. The aforementioned problem is transferred into a Markov Decision Process to model the changing environment with the trans…

Latency Minimization Oriented Radio and Computation Resource Allocations for 6G V2X Networks with ISCC
Incorporating mobile edge computing (MEC) and integrated sensing and communication (ISAC) has emerged as a promising technology to enable integrated sensing, communication, and computing (ISCC) in the sixth generation (6G) networks. ISCC is particularly attractive for vehicle-to-everything (V2X) applications, where vehicles perform ISAC to sense the environment and simultaneously offload the sensing data to roadside base stations (BSs) for remote processing. In this paper, we investigate a part…
