IEEE AccessTime-frequency analysis (TFA) can provide relevant information about subsurface reservoirs, which is essential in reservoir identification. Traditional TFA methods are limited by resolution, resulting in unreliable seismic interpretation.

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Chirped Integrated Bragg Grating Design
PhotonicsWe analyze the two classic methods for chirped Integrated Bragg Gratings (IBGs) in Silicon-on-Insulator technology using the transfer matrix method based on the effective refractive index (neff) technique, which translates the geometry of an IBG into a ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Characteristics-Based Design of Generalized- Exponent Bandpass Filters
IEEE AccessWe develop characteristics-based filter design methods for certain related classes of IIR bandpass filters that have a peak including Generalized-Exponent Filters (GEFs) which are represented as second-order filters raised to non-unitary exponents.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Coplanar waveguide-fed ultra-wideband planar antenna with WLAN-band rejection
Journal of Microwaves, Optoelectronics and Electromagnetic ApplicationsA compact coplanar waveguide (CPW)-fed ultra-wideband (UWB) antenna is proposed with band-notched characteristic. The antenna has compact size of 29 x 31 mm². A novel wide polygon-slot is inserted on the antenna to obtain good impedance matching and wide

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Allpass-Based Chirp Design With Perfect Pulse Compression Property
IEEE Open Journal of Signal ProcessingChirp waveforms are widely used in radar, sonar, acoustics, and other sensing systems due to their desirable pulse-compression behavior. However, standard chirp signals like linear frequency modulation (LFM) waveforms inevitably produce sidelobes that ...
