Dysregulated ribosome quality control in human diseases

open access: yesThe FEBS Journal, Volume 292, Issue 5, Page 936-959, March 2025.
Ensuring the synthesis of full‐length, correctly folded proteins is vital for maintaining homeostasis. If a translating ribosome stalls, the trailing ribosomes collide into it, which if left unresolved leads to deleterious effects on the cell due to the accumulation of protein aggregates.

Demonstration of negative signal delay with short-duration transient pulse

open access: yes, 2011
This paper introduces theoretic and experimental analyses of short-duration pulse propagation through a negative group delay (NGD) circuit. The basic analysis method of this electronic circuit operating in baseband and microwave frequencies is ...

Remote monitoring of social attention in neurogenetic syndromes and idiopathic neurodevelopmental disability

open access: yesAutism Research, Volume 18, Issue 2, Page 334-348, February 2025.
Abstract Social attention is a key aspect of neurodevelopment and is significantly altered in neurodevelopmental genetic syndromes and many individuals with idiopathic autism spectrum disorder (ASD). The primary aim of the present study was to examine the psychometric properties of webcam‐collected social attention measurements, including four new ...

Dual-Band Negative Group Delay Microwave Circuit With Low Signal Attenuation and Arbitrary Frequency Ratio

open access: yesIEEE Access, 2020
A dual-band negative group delay (NGD) microwave circuit with low signal-attenuation and arbitrary frequency ratio is proposed. Closed-form analytical equations are derived for the design of the proposed dual-band negative group delay circuit (NGDC) with

A note on the bandwidth of negative group delay filters

open access: yesInternational Journal of Circuit Theory and Applications, Volume 53, Issue 1, Page 477-484, January 2025.
An updated definition of group delay bandwidth in analog filters is introduced in this work. Unlike existing definitions, this new definition considers simultaneously the value of the group delay and filter gain, leading to minimized distortion in the filter output. In addition, it offers the capability of handling wide‐band signals without introducing

Novel Gysel Power Dividers with Negative Group Delay Characteristics

open access: yesInternational Journal of Antennas and Propagation, 2019
A novel Gysel power divider with negative group delay (NGD), good matching, and low insertion loss is proposed. Resistors connected with short-circuited coupled lines (RCSCL) are shunted at output ports of the Gysel power divider to obtain NGD ...

Critical care unit bed availability and postoperative outcomes: a multinational cohort study

open access: yesAnaesthesia, Volume 79, Issue 11, Page 1165-1179, November 2024.
Summary Background Critical care beds are a limited resource, yet research indicates that recommendations for postoperative critical care admission based on patient‐level risk stratification are not followed. It is unclear how prioritisation decisions are made in real‐world settings and the effect of this prioritisation on outcomes.

New insights into the therapeutic options to lower lipoprotein(a)

open access: yesEuropean Journal of Clinical Investigation, Volume 54, Issue 9, September 2024.
Elevated levels of lipoprotein(a) [Lp(a)] represent a risk factor for atherosclerotic cardiovascular diseases and are today considered an appealing pharmacological target over and above the canonical therapeutic targets. This review discusses the impact of the currently available treatments on Lp(a) levels as well as it aims at presenting the new ...
