Assessment of digital light processing (DLP) projector stimulators for visual electrophysiology
Authors: Marmoy Oliver R. , Thompson Dorothy A. 
Published: January 2023

Abstract
Introduction
Visual electrophysiology tests require the use of precise and calibrated visual display units (VDUs). Existing VDUs for presenting structured stimuli are now mostly obsolete, with modern solutions limited or unsuitable for clinical testing. Digital light processing (DLP) laser projectors have recently become commercially available and this study aimed to assess their suitability as VDUs for visual electrophysiology testing.

Methods
This study consisted of two sections. The first was a photometric study of two DLP laser projectors (Viewsonic LS831WU and HiSense 100L5FTUK) to assess luminance, contrast, spectral and temporal characteristics of the stimulus. The second was a physiological study comparing pattern electroretinograms (PERG) and visual evoked potentials (PVEPs) amplitudes and peak-times recorded using a DLP laser projector, photometrically and spatially matched to existing plasma VDUs at our institution (Pioneer Electronics Corporation, PDP422MXE).

Results
The Viewsonic DLP laser projector was capable of high luminance levels (0–587.5 cd/m2) whilst maintaining contrast above 93%. The temporal properties showed fast rise and fall times of 0.5–1 ms and 0.5–1 ms, respectively, without any transient luminance change with reversals. The device required a warm-up time of at least 2 min until reaching near maximal luminance. The second (Hisense) device was observed to have a detrimental input lag jitter so was not used for any further analysis. PERGs and PVEPs showed high agreement and correlation (r = 0.766–0.905) between the Viewsonic DLP device and existing plasma VDUs. No significant differences were observed for P50 and P100 peak-time (p =  > 0.05), however P50, N95 and P100 amplitudes were all significantly larger for the DLP device (p =  < 0.05).

Discussion
The DLP laser projector tested in this study is a viable and practical replacement VDU for clinical electrophysiology tests of vision. The device is easily capable of meeting ISCEV standards, and showed PERG and PVEP amplitudes larger than existing systems despite photometric and spatial matching. The DLP laser projectors are capable of very large field sizes so are beneficial for paediatric testing or those wishing to examine large field responses. Importantly, it was observed that some devices may suffer input lag jitter, therefore, individual calibration and assessment of DLP projection systems is an important consideration before clinical implementation.
Applying the Canadian Low-Risk Gambling Guidelines to Gambling Harm Reduction in England
Authors: Rochester Eleanor , Cunningham John A. 
Published: January 2023

AbstractThere is a need for evidence-based guidelines for gamblers who wish to reduce their risk of harm by setting self-directed limits on their gambling. Recognizing this, the Canadian Low-Risk Gambling Guidelines were developed using data from 8 countries to establish the relationship between gambling behaviour and harm. The guidelines include recommended limits on gambling spending as a percentage of income, gambling frequency, and number of types of games played. However, the developers of the LRGG’s did not include UK data in their analysis. This study analyzes data from Health Survey England to assess the applicability of the Canadian Low-Risk Gambling Guidelines to gamblers in England. Using HSE data from 2016 to 2018, we generated risk curves for the relationship between 2 dimensions of gambling behaviour—frequency of gambling sessions and number of types of games played—and gambling harm. We defined harm as a score of 1 or above on the Problem Gambling Severity Index. HSE does not include questions on gambling spending, therefore this was not assessed. The relationship observed between frequency and types of gambling and harm among HSE respondents was similar to the risk curves generated for the development of the Canadian LRGG’s. Gamblers in England who gambled twice weekly or more, or who played 3 or more types of games, were significantly more likely to experience harm from gambling than those who gambled below these limits. The Canadian LRGG’s may potentially be applied to gambling harm reduction efforts in England. More research is needed to determine the acceptability of these guidelines to people who gamble in England.
Efficacy of a School-Based Mental Health Intervention Based on Mindfulness and Character Strengths Use Among Adolescents: a Pilot Study of Think Happy-Be Happy Intervention

Published: January 2023

AbstractThis study investigated the efficacy of a school-based intervention (8 sessions of 45 min) based on mindfulness and character strengths use (i.e., “Think Happy-Be Happy”). A quasi-experimental study, including assessments at baseline, post-intervention (i.e., one week after the intervention), and follow-up (i.e., six months after the intervention) was performed. Results at post-intervention revealed that adolescents who participated in all intervention sessions experienced significantly increased well-being (i.e., emotional, psychological, and social well-being) and decreased hyperactivity/inattention symptoms and peer-related problems compared to adolescents who did not participate in the intervention. The “intention to treat” analyses showed that adolescents who started the intervention, regardless of the number of sessions they attended, experienced significantly decreased hyperactivity/inattention symptoms compared to adolescents who did not participate in the intervention. However, significant outcomes were not maintained at follow-up. Nevertheless, this study demonstrates that integrating mindfulness with strengths use in school-based interventions might have the potential to promote the mental health of adolescents in terms of both increased well-being and reduced psychological problems.
Beyond ambidexterity: universities and their changing roles in driving regional development in challenging times

Published: January 2023

AbstractAround the world today, universities are expected to play a unique role as creators of regional growth and innovation. While there appears to be a consensus that the role of universities has been expanded, critiques show that the contribution of universities to their regions is still not well defined. There have been some developments in the literature on the concept of modern universities such as the triple helix, entrepreneurial university and engaged university. However, those concepts focus on enforcing universities’ roles in a single domain such as entrepreneurship, innovation, or civic engagement. Little is known about how universities can facilitate regional growth that goes beyond knowledge transfer activities such as spin-off creation, licensing, and patenting. This paper contributes to a more comprehensive understanding of universities’ role in regional growth through the theoretical lens of ambidexterity. Using ambidexterity, universities with a regional focus were distinguished from those engaged in research commercialization and traditional third-mission roles. Through two case studies, this study found that teaching, research, and engagement should not be separated, since they can serve both economic and social missions. As a result, a new model of multidextrous universities is proposed where universities meet both economic and social missions through teaching, research, and engagement. Contrary to previous contributions which presented universities as ambidextrous organizations where tension appears only between research commercialization and research publication or between teaching and research, this study suggests that universities need to overcome tensions and incorporate a sense of place in all activities to successfully contribute to regional growth.
An Efficient Recurrent Adversarial Framework for Unsupervised Real-Time Video Enhancement

Published: January 2023

AbstractVideo enhancement is a challenging problem, more than that of stills, mainly due to high computational cost, larger data volumes and the difficulty of achieving consistency in the spatio-temporal domain. In practice, these challenges are often coupled with the lack of example pairs, which inhibits the application of supervised learning strategies. To address these challenges, we propose an efficient adversarial video enhancement framework that learns directly from unpaired video examples. In particular, our framework introduces new recurrent cells that consist of interleaved local and global modules for implicit integration of spatial and temporal information. The proposed design allows our recurrent cells to efficiently propagate spatio-temporal information across frames and reduces the need for high complexity networks. Our setting enables learning from unpaired videos in a cyclic adversarial manner, where the proposed recurrent units are employed in all architectures. Efficient training is accomplished by introducing one single discriminator that learns the joint distribution of source and target domain simultaneously. The enhancement results demonstrate clear superiority of the proposed video enhancer over the state-of-the-art methods, in all terms of visual quality, quantitative metrics, and inference speed. Notably, our video enhancer is capable of enhancing over 35 frames per second of FullHD video (1080x1920).
Notes on Isoglossinae (Acanthaceae) in Madagascar, with four new species of Isoglossa
Authors: Darbyshire Iain , Onjalalaina Guy E. , Callmander Martin W. , Phillipson Peter B. , Kiel Carrie A. 
Published: January 2023

SummaryCurrent generic delimitation in subtribe Isoglossinae of Acanthaceae is discussed using available morphological and molecular data. Particular consideration is given to the small genera endemic to Madagascar — Celerina Benoist, Melittacanthus S.Moore, Sphacanthus Benoist and the illegitimate Conocalyx Benoist — and how these relate to the current circumscription of Isoglossa Oerst. The relative merits and challenges of recognising a broadly circumscribed Isoglossa are considered. Isoglossa s.l. is readily recognisable by combining a bilabiate corolla, with an androecium comprising two bithecous stamens and lacking staminodes, and with the presence of gürtelpollen (i.e. bipororate pollen, circular in apertural view and with a pronounced interapertural “girdle” of tectate exine), whilst the segregate genera as currently defined are not separable morphologically. However, the limited molecular phylogenetic data available to date indicate that Isoglossa s.l. is paraphyletic. Pending further molecular studies of this group to clarify generic delimitation, it is proposed that all new taxa in bithecous Isoglossinae should be described in Isoglossa as an interim solution. Four new species of Isoglossa are described: I. eburnea Onjalal. & I.Darbysh., I. pterocalyx I.Darbysh. & Phillipson, I. pseudoanisotes I.Darbysh. and I. conocalyx I.Darbysh. & Callm., the lattermost of which is based on Conocalyx laxus Benoist nom. illegit. In addition, Justicia onilahensis Benoist (including Ritonia poissonii Benoist) and Anisotes perplexus T.F.Daniel, Letsara & Martín-Bravo are transferred to Isoglossa, and three names within Justicia L. are synonymised within existing taxa in Isoglossinae. Lectotypes are selected for Sphacanthus brillantaisia Benoist, S. humbertii Benoist and Justicia subpaniculata Benoist (=Celerina seyrigii Benoist var. egena Benoist).

Abstract
Objectives
Fatigue is a prevalent and burdensome problem in patients with inflammatory bowel disease (IBD), even when the disease is in remission. Evidence-based psychological interventions for managing IBD-related fatigue are still lacking. This study aimed to examine the efficacy of Mindfulness-Based Cognitive Therapy (MBCT) for reducing fatigue in patients with IBD in remission.

Method
A two-arm multicenter randomized controlled trial was conducted in 113 IBD outpatients in remission with elevated levels of fatigue (i.e., Checklist Individual Strength — subjective fatigue ≥ 27). Patients were randomly assigned to an 8-week MBCT program (n = 56) or a waiting-list condition (n = 57). All participants completed questionnaires at baseline and directly post-intervention. The primary outcome was fatigue, assessed with the Checklist Individual Strength-20. Secondary outcomes included fatigue interference in daily life, depression, anxiety, and IBD-specific quality of life. Analysis of covariance (ANCOVA) was performed to examine treatment outcomes.

Results
Intention-to-treat analyses showed significant reductions in the subjective experience of fatigue in patients receiving MBCT, compared to the waiting-list control condition (p = 0.03; Cohen’s d = 0.46; clinically relevant improvement in 36% vs. 10%). No significant effects were found on other fatigue aspects or secondary outcomes.

Conclusions
An 8-week MBCT group program effectively reduced the subjective experience of fatigue in patients with IBD in remission. Results do not support effects for other aspects of fatigue or secondary outcomes.

Map of thrombogenesis in viral infections and viral-driven tumours

Published: January 2023

AbstractViruses are pathogenic agents responsible for approximately 10% of all human cancers and significantly contribute to the global cancer burden. Until now, eight viruses have been associated with the development of a broad range of malignancies, including solid and haematological tumours. Besides triggering and promoting oncogenesis, viral infections often go hand-in-hand with haemostatic changes, representing a potential risk factor for venous thromboembolism (VTE). Conversely, VTE is a cardiovascular condition that is particularly common among oncological patients, with a detrimental impact on patient prognosis. Despite an association between viral infections and coagulopathies, it is unclear whether viral-driven tumours have a different incidence and prognosis pattern of thromboembolism compared to non-viral-induced tumours. Thus, this review aims to analyse the existing evidence concerning the association of viruses and viral tumours with the occurrence of VTE. Except for hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infection, which are associated with a high risk of VTE, little evidence exists concerning the thrombogenic potential associated with oncoviruses. As for tumours that can be induced by oncoviruses, four levels of VTE risk are observed, with hepatocellular carcinoma (HCC) and gastric carcinoma (GC) associated with the highest risk and nasopharyngeal carcinoma (NPC) associated with the lowest risk. Unfortunately, the incidence of cancer-related VTE according to tumour aetiology is unknown. Given the negative impact of VTE in oncological patients, research is required to better understand the mechanisms underlying blood hypercoagulability in viral-driven tumours to improve VTE management and prognosis assessment in patients diagnosed with these tumours.
Delineating the main structural outlines and the petrophysical properties of the Albian-upper Cretaceous Reservoirs using seismic and well log data, Shushan Basin, north Western Desert, Egypt

AbstractThis study concerns with delineating and analyzing the subsurface structural setting of Khalda Oil Field at Shushan Basin as a key factor for evaluating the petrophysical properties and the deliverability of the Bahariya Formation. Shushan Basin is considered one of the most prospective basins in the Western Desert. The oil is trapped within a gentle seismically defined anticline that contains a series of coastal sandstone reservoirs interbedded with a neritic and tidal flat mudstone and a few carbonate interbeds of the Albian-Cenomanian Bahariya Formation forming multiple oil-bearing sandstone reservoirs. A set of borehole logging and seismic data were available, tied, processed, and mapped to delineate the predominant structures in the study area. Results show the implication of the NW–SE, NE–SW, and E–W gravity faulting on the Bahariya and the overlying Abu Roash formations. This set of gravity faults is attributed to the Mesozoic tensional stresses. The depth structure contour maps on the upper surfaces of the Lower and Upper Bahariya members reveal the presence of some NE–SW gravity faults that dissected the Khalda Field into some slightly tilted blocks, shallowing in depth to the south as deepening to the north. Besides, the study area has been affected later in the Jurassic by E–W gravity faults during the Atlantic Ocean opening. This faulting trend was changed later into the NE–SW direction as a result of the movement of North Africa against Laurasia. The petrophysical analysis indicated that the Lower Bahariya sandstone reservoir has a good reservoir quality (16 ≤ ∅ ≤ 25%, 53 ≤ Sw ≤ 59%, 6.0 ≤ Vsh ≤ 32.2%, and good net-pay thickness 18.0–38.0 ft). It is revealed that the drilled wells penetrating the crest of the anticline are prospective while that located in the anticline flanks are water-bearing recommending exploration away from the anticline flanks. By applying this workflow, it is possible to explore for the similar subsurface hydrocarbons-bearing sequences in the Western Desert and North Africa in future exploitation plans.
The aggregate effects of government income transfers shocks: EU evidence
Authors: Párraga Rodríguez Susana 
Published: January 2023

AbstractThis paper estimates the aggregate effects of government income transfers shocks for a sample of EU countries. I construct a new measure of transfers shocks based on a dataset by public finance experts of the European System of Central Banks (ESCB). The identification strategy consists of a narrative analysis of policy actions in old age pensions reported in the ESCB dataset. I find that increases in old age pensions have a positive impact on aggregate expenditure components and employment consistent with a multiplier effect between 0 and 1.

Applying Magnetic Curvature to MMS Data to Identify Thin Current Sheets Relative to Tail Reconnection
Authors: Rogers A. J. , Farrugia C. J. , Torbert R. B. , Rogers T. J. 
Published: January 2023

AbstractThin current sheets (TCSs) have been postulated to be a necessary precondition for reconnection onset. Magnetic reconnection X‐lines in the magnetotail have been observed to be more common duskward of midnight. We take advantage of the MMS tetrahedral formation during the 2017–2020 MMS tail seasons to calculate the thickness of the cross‐tail neutral sheet relative to ion gyroradius. While a similar technique was applied to Cluster data, current sheet thickness over a broader range of radial distances has not been robustly explored before this study. We compare our analysis to recent theories regarding mechanisms of tail current sheet thinning and to recent simulations. We find MMS spent more than twice as long in ion‐scale TCSs in the pre‐midnight sector than post‐midnight, despite nearly even plasma sheet dwell time. The dawn‐dusk asymmetry in the distribution of Ion Diffusion Regions, as previously reported in relation to regions of TCSs, is also analyzed.
Interplay of Altitude, Ground Track Coverage, Noise, and Regularization in the Spatial Resolution of GRACE Gravity Field Models
Authors: McGirr R. , Tregoning P. , Allgeyer S. , McQueen H. , Purcell A. P. 
Published: January 2023

AbstractModels of the temporal gravity field derived from space gravity missions are typically produced with monthly temporal resolution and ∼300‐km spatial resolution. However, variations in instrument performance and altitude of the Gravity Recovery and Climate Experiment (GRACE) mission impact the spatial resolution that can be achieved month‐to‐month. As the altitude of the orbits of the twin spacecraft vary throughout the mission, so does the ability of the observations to recover certain components of the temporal gravity field. The spatial resolution of GRACE observations should increase as the altitude decreases throughout the mission because the reduced altitude intensifies the gravity signals acting on the satellites. Simulations using actual GRACE altitude and ground track coverage and realistic noise levels confirm this predicted influence of the altitude of the satellites on the accuracy of the estimated solutions. Solutions with larger mass concentration elements (mascons) are more numerically stable as the satellite altitude decreases but they suffer from greater error caused by the inability to properly represent spatial variations of signals within mascons, referred to as intramascon variability. Mascons as small as ∼150 × 150 km (i.e., ∼1.5 arc‐degree) reduce the intramascon variability and, with appropriate regularization, yield the most accurate solutions, especially during the low‐altitude periods of the GRACE mission. Importantly, unlike spherical harmonic solutions, regularized mascon solutions are not degraded during resonant orbit months, and are of comparable quality to months with full ground track coverage.
