Clipping Noise in Visible Light Communication Systems with OFDM and PAPR Reduction

Photonics
This paper presents an analytical study of signal clipping that leads to the noise/distortion in the waveform of DC-biased optical orthogonal frequency division multiplexing (DCO-OFDM)-based visible light communication (VLC) systems.

Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat

Integrative Zoology, EarlyView.
After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...

A 3-3.7GHz Time-Difference Controlled Digital Fractional-N PLL With a High-Gain Time Amplifier for IoT Applications

IEEE Access, 2022
This paper presents analyses of jitter and reference spur of a digital PLL using a phase-frequency detector (PFD) and a time amplifier (TA). In the PFD-TA PLL, the TA amplifies a phase error between a reference clock and a divided feedback clock.

Trends and socio‐economic disparities in chronic lymphocytic leukaemia 2014–2022: An England‐wide cohort study from the UNCOVER group

British Journal of Haematology, EarlyView.
Summary To re‐evaluate chronic lymphocytic leukaemia (CLL) epidemiology in the era of modern therapy, data were extracted from the English National Cancer Registration Dataset (NCRD). A total of 34 427 consecutive diagnoses of CLL were recorded (2014–2022), the largest European dataset on record.

The nitty‐gritty of vascular permeability in cancer: targeting blood endothelium to control metastases

British Journal of Pharmacology, EarlyView.
Blood vascular permeability is a hallmark of cancer and acts as an active driver of metastatic dissemination. Metastasis accounts for the vast majority of cancer deaths, yet most work has focussed on tumour‐intrinsic traits and angiogenesis, while the specific contribution of endothelial barrier regulation to intravasation and extravasation remains ...

Effects of Meloidogyne incognita on agronomic parameters and structural changes in eggplant (Solanum gilo Raddi) roots treated with Purpureocillium lilacinum

Plant Biology, EarlyView.
Meloidogyne incognita impairs eggplant growth through gall formation with changes in root cell wall components and vascular tissue disruption, while the biocontrol agent Purpureocillium lilacinum mitigates these effects by reducing nematode infection. Abstract Meloidogyne spp. induce structural changes during the development of root‐knot galls, leading
