Molecular Oncology, EarlyView.Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma
Molecular Oncology, EarlyView.Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

Bandpass Sigma–Delta Modulation: The Path toward RF-to-Digital Conversion in Software-Defined Radio
Chips, 2023 This paper reviews the state of the art on bandpass ΣΔ modulators (BP-ΣΔMs) intended to digitize radio frequency (RF) signals. A priori, this is the most direct way to implement software-defined radio (SDR) systems since the analog/digital interface is ...

Adaptive selfcalibrating delta-sigma modulators
Electronics Letters, 1992 The concept of an adaptive Delta Sigma A/D convertor is introduced. A selfcalibrating adaptive implementation is described. The new scheme appears to be very effective for improving the resolution and the signal-to-noise ratio of delta-sigma modulators which rely on error cancellation to achieve a high signal-to-noise ratio.

RIPK4 function interferes with melanoma cell adhesion and metastasis
Molecular Oncology, EarlyView.RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

A Hierarchical Modulation Enabled SNR Allocable Delta-Sigma Digital Mobile Fronthaul System
IEEE Photonics Journal, 2022 Internet of everything is being build up rapidly, which causes much higher requirements towards the flexibility of communication resources, especially the adaptivity of the fronthaul to various transmission distances and capacities.

Design Sign of Delta Sigma Wattmeter [PDF]
, 2009 Instantaneous power in a load is measured by multiplying the voltage across it by the current flowing through it. The multiplication is achieved in a delta sigma wattmeter by using two samplers rather than a multiplier.

SNDR sensitivity analysis for cascaded ΣΔ modulators [PDF]
, 2000 Cascade, single and multi-bit, ΣΔ architectures provide stable, high order quantization noise shaping used in high resolution A/D conversion. One major disadvantage of cascaded ΣΔ topologies is the extreme SNDR sensitivity to gain mismatch between the ...

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.
