A stability perspective of bio-inspired UAVs performing dynamic soaring optimally.

Bioinspir Biomim 2021 Jul 29. Epub 2021 Jul 29.

Air University, Aerospace & Aviation Campus, Air University, Aerospace & Aviation Campus, Kamra, 44200, PAKISTAN.

Dynamic soaring phenomenon, exhibited by soaring birds, has long been a biological inspiration for the aerospace and control engineering communities. If this fascinating phenomenon, which allows soaring birds to perform almost un-powered flights using wind shear, can be mimicked by Unmanned-Aerial-Vehicles (UAVs), then UAVs performance have a substantial potential to enhance technologically and economically as well. Even though there have been considerable amount of research covering the modeling, optimization, control and simulation aspects of different UAVs performing dynamic soaring, there is little to non conclusive work analyzing the stability of such UAVs about the soaring orbits.

Epilepsy in LAMA2-related muscular dystrophy: A systematic review of the literature.

Seizure 2021 Jul 21;91:425-436. Epub 2021 Jul 21.

Department of Developmental Neuroscience, IRCCS Fondazione Stella Maris, Calambrone, Pisa, Italy. Electronic address:

Epilepsy is a common, often severe, feature of LAMA2-related muscular dystrophy (LAMA2-RD) and could represent its onset and main manifestation, even in the absence of overt muscle involvement. To date, there is no systematic characterization of epilepsy in LAMA2-RD, and its impact on neurodevelopment and on the clinical course remains poorly established. In view of this knowledge gap, we conducted a systematic review of the literature and, as an illustrative example, reported the clinical case of a boy with late-onset LAMA2-related limb-girdle muscular dystrophy presenting with severe epilepsy.

Monoclonal antibody charge variant characterization by fully automated four-dimensional liquid chromatography-mass spectrometry.

J Chromatogr A 2021 Jul 14;1653:462409. Epub 2021 Jul 14.

RIC group, President Kennedypark 26, Kortrijk 8500, Belgium; Separation Science Group, Department of Organic and Macromolecular Chemistry, Ghent University, Krijgslaan 281-S4, Ghent B-9000, Belgium. Electronic address:

Fully automated characterization of monoclonal antibody (mAb) charge variants using four-dimensional liquid chromatography-mass spectrometry (4D-LC-MS) is reported and illustrated. Charge variants resolved by cation-exchange chromatography (CEX) using a salt- or pH-gradient are collected in loops installed on a multiple heart-cutting valve and consequently subjected to online desalting, denaturation, reduction and trypsin digestion prior to LC-MS based peptide mapping. This innovation which substantially reduces turnaround time, sample manipulation, loss and artefacts and increases information gathering, is described in great technical detail, and applied to characterize the charge heterogeneity associated with three therapeutic mAbs.

"Does that mean I can't use my phone to pay when I'm in the Maccas drive thru?": Younger drivers' uncertainty and attitude toward smartphone law and punishment.

Accid Anal Prev 2021 Jul 26;160:106314. Epub 2021 Jul 26.

Monash University Accident Research Centre, Monash University, Australia.

This study employed a mixed methods approach (a survey [n = 2,774] and focus groups [n = 16]) to understand the perceptions of younger drivers (18-25) on current smartphone laws in the Australian state of Victoria. First, by analysing quantitative data gathered from an online survey regarding smartphone laws, perceptions of punishment when breaking the law, and attitudes to both the law and fines, this study found younger drivers were less likely to understand the law around phone use while driving, even after direct or indirect experience with police. Additionally, the severity and impact of fines were perceived as more impactful and severe among younger drivers, women, and those on lower incomes, and the most common types of illegal use younger drivers engaged with were navigation, music applications, and hands-free calling, mostly facilitated through Bluetooth with their device placed out of sight.

Probing the transport of Ni(II) ions through the internal tunnels of the Helicobacter pylori UreDFG multimeric protein complex.

J Inorg Biochem 2021 Jul 22;223:111554. Epub 2021 Jul 22.

Laboratory of Bioinorganic Chemistry, Department of Pharmacy and Biotechnology, Alma Mater Studiorum - University of Bologna, viale G. Fanin 40, I-40127 Bologna, Italy. Electronic address:

The survival of several pathogenic bacteria, such as Helicobacter pylori (Hp), relies on the activity of the nickel-dependent enzyme urease. Nickel insertion into urease is mediated by a multimeric chaperone complex (HpUreDFG) that is responsible for the transport of Ni(II) from a conserved metal binding motif located in the UreG dimer (CPH motif) to the catalytic site of the enzyme. The X-ray structure of HpUreDFG revealed the presence of water-filled tunnels that were proposed as a route for Ni(II) translocation. Read More

A systematic review and meta-analysis of the association between expressive suppression and positive affect.

Clin Psychol Rev 2021 Jul 14;88:102068. Epub 2021 Jul 14.

Georgia State University, Department of Psychology, 140 Decatur St SE, 1172 Urban Life, Atlanta, GA, United States of America. Electronic address:

People differ in their self-reported propensities to experience positive affect (PA). Even those prone to internalizing symptoms show varied proclivities to PA; social anxiety (SA), for instance, unlike other types of anxiety, shows a strong negative association with PA that cannot be explained by diminished reward sensitivity. Heightened reliance on suppression of emotional displays (expressive suppression; ES) may be an alternate contributor to attenuated PA among people with elevated SA, relative to people with other types of anxiety.
