Wideband single-layer D-band patch antenna with parasitic elements and superstrate loading

This paper proposes a D-band patch antenna featuring four parasitic elements and a loaded superstrate layer. Inspired by a previous parasitic patch antenna design, the new structure is synthesized from scratch using characteristic mode analysis. The new design features different operating principles that enable low-cost single-layer fabrication on PCB HDI technology, while retaining wideband opera

Verification of multi-structure targeting in chronic microelectrode brain recordings from CT scans

Background: Large-scale microelectrode recordings offer a unique opportunity to study neurophysiological processes at the network level with single cell resolution. However, in the small brains of many experimental animals, it is often technically challenging to verify the correct targeting of the intended structures, which inherently limits the reproducibility of acquired data. New method: To mit

By incorporating a central hexagonal slot together with four elongated slots and two short slots, the proposed antenna tailors high-order modes to achieve the desired radiation characteristics. By analyzing the electric field, the distribution in various regions is decomposed an

Analyzing Coverage Probability in Full-Duplex Two-Tier Networks with Offloading and Resource Partitioning

Full-duplex (FD) communication improves spectral efficiency by allowing simultaneous transmission and reception on the same frequency band. This paper analyzes a two-tier network consisting of macrocells and picocells, where base stations (BSs) operate in FD mode while users operate in half-duplex (HD) mode. However, interference remains a major challenge in these systems, significantly impacting

The wireless power transfer system comprises a power transmit device arranged to transfer power over an inductive wireless power transfer interface operating at a transmit frequency to a power receive device. The wireless power transfer system is adapted to transfer information

Roof-glass integrated microstrip antenna for vehicular SDARS applications

In this paper, we propose the design of a roof-glass integrated microstrip antenna for vehicular SDARS tuners. The proposed microstrip antenna is sandwiched inside a multi-layer roof glass and uses a solar-heat reduction coating on the bottom side of the glass as ground plane. To offset the effect of the lossy glass, parasitic elements are added to enhance the antenna gain. Simulation results show

Scalable D-band antenna with coplanar and stacked parasitic elements for low-cost antenna-in-package

The unquenchable thirst for bandwidth to support next-generation wireless systems is increasingly bringing D-band into the spotlight. This work proposes a scalable D-band patch antenna that features both coplanar and stacked parasitic patch structures. By leveraging inter-patch coupling, different coplanar parasitic elements are excited across different frequency bands, enabling multi-mode operati

Design of low-cost sub-THz antennas for distributed deployment in 6G

Although 6G is not only about higher data rates, its envisioned peak data rate of 1 terabits per second requires larger frequency bandwidth than what 5G millimeter wave bands offer. Therefore, new frequency bands have been allocated in the sub-THz range for 6G applications. This paper reviews the concept of distributed deployment to provide coverage in sub-THz bands, focusing on the design and imp

Vulnerable Normality: Popular Neuroimaging and the Discursive Logic of the (Dis)able(d) Brain

The aim of this article is to analyse popular neuroimaging of (dis)able(d) brains as a cultural phenomenon, as well as to explore how there has been, during the last decades, a subtle but important change in the way “normal” brains are depicted in popular science. Popular neuroimaging is introduced and used as an empirical basis to analyse what Fiona Kumari Campbell sees as a critique against able

A data-driven approach for understanding invalid bug reports: An industrial case study

Context:Bug reports created during software development and maintenance do not always describe deviations from a system’s valid behavior. Such invalid bug reports may consume significant resources and adversely affect the prioritization and resolution of valid bug reports. There is a need to identify preventive actions to reduce the inflow of invalid bug reports. Existing research has shown that m

Epilepsy is one of the most common neurological disorders that is characterized by recurrent and unpredictable seizures. Wearable systems can be used to detect the onset of a seizure and notify family members and emergency units for rescue. The majority of state-of-the-art studies in the epilepsy domain currently explore modern machine learning techniques, e.g., deep neural networks, to accurately

Dynamic Server Provisioning with Queue Stabilization in Data Centres

When load balancing data centres with all serversactive to serve jobs, the result can be excessive energy usage. Onthe other hand, using dynamic server provisioning, the numberof servers that serve requests can be reduced by turning off idleservers and thereby save energy. However, such a scheme, usuallyincreases the risk of instability of server queues. In this work,we analyze the trade-off betwe

Time dependence in diffusion MRI predicts tissue outcome in ischemic stroke patients

Purpose: Reperfusion therapy enables effective treatment of ischemic stroke presenting within 4–6 hours. However, tissue progression from ischemia to infarction is variable, and some patients benefit from treatment up until 24 hours. Improved imaging techniques are needed to identify these patients. Here, it was hypothesized that time dependence in diffusion MRI may predict tissue outcome in ische

Modifying Backoff Freezing Mechanism to Optimize Dense IEEE 802.11 Networks

From experience, it has been well known that the performance of IEEE 802.11 wireless local area networks significantly drops in dense settings, largely driven by poor capacity of the medium access control (MAC) layer. The current 802.11 MAC mechanism utilizes a contention window (CW) for random access, and the CW size is dictated to take discrete values from a bounded finite set. In this paper, wi
