Abstract
While there is evidence that long-chain n-3 PUFA supplementation benefits mood, the extent to which a single high dose of n-3 PUFA can induce acute mood effects has not been examined. The present study investigated whether a single dose of a DHA-rich powder affects self-reported mood in middle-aged males during elevated cognitive demand. In a randomised, double-blind, placebo-controlled trial with a balanced crossover design, twenty-nine healthy males (age M = 52.8 years, sd = 5.3) were administered a powder (in a meal) containing 4·74 g n-3 PUFA (DHA 4020 mg; EPA 720 mg) or placebo in random order on two different testing days separated by a washout period of 7 ± 3 d. Participants completed mood assessments before and after completing two cognitive test batteries at baseline and again 3·5–4·0 h following the consumption of the active treatment or placebo. While completion of the cognitive test batteries increased negative mood, differential effects for alertness (P = 0·008) and stress (P = 0·04) followed consumption of the DHA-rich powder compared with placebo. Although alertness declined when completing the cognitive batteries, it was higher following consumption of the DHA-rich powder compared with placebo (P = 0·006). Conversely, stress was lower following consumption of the DHA-rich powder relative to placebo, though this difference only approached significance (P = 0·05). Overall, results from this pilot study demonstrate that a single high dose of n-3 PUFA may deliver acute mood benefits following elevated cognitive demand in healthy middle-aged males.
Programming and reasoning about actors that share state
Authors: CALDWELL SAM , GARNOCK-JONES TONY , FELLEISEN MATTHIAS 
Published: December 2024

Abstract
Actor languages realize concurrency via message passing, which most of the time is easy to use. Empirical code inspection provides evidence, however, that on occasion, programmers wish to have an actor share some of its state with others. The dataspace model adds a tightly controlled state-exchange mechanism, dubbed dataspace, to the actor model for just this purpose. Experience with dataspaces suggests that this form of sharing calls for linguistic constructs that allow programmers to state temporal aspects of actor conversations. In response, this paper presents the facet notation: its theory, its type system, its behavioral type system, and some first experiences with an implementation.
Brief imagery based metacognitive intervention for flashforwards in psychosis: a fixed baseline case series
Authors: Sivarajah Nithura , Taylor Christopher D.J. , Steel Craig 
Published: December 2024

Abstract

Background:
Distressing mental images are common in people with psychosis. The central role of metacognitive difficulties in psychosis suggests that metacognitive interventions with imagery properties could play a central role in managing distressing mental imagery. A brief imagery-based metacognitive intervention was developed to target the control mechanism of distressing mental images in psychosis.

Aims:
A fixed baseline case series was designed to investigate whether the intervention was acceptable, feasible and effective.

Method:
Eight participants who met criteria for a schizophrenia spectrum diagnosis and experienced distressing future-oriented mental images took part in the case series, which consisted of three phases; baseline, intervention, and follow-up. Symptoms of anxiety, depression, persecutory delusions and schemas were assessed pre- and post-intervention, and qualitative feedback was collected at follow-up.

Results:
The metacognitive intervention was feasible, acceptable, and rated as highly satisfactory. One participant dropped out at the baseline phase. No adverse events were reported. Positive change scores with a decrease in symptoms were reported for anxiety, depression, persecutory delusions, and schemas. Tau-U analysis showed positive trends and high effect sizes on mental imagery characteristics at follow-up.

Conclusion:
Our findings suggest that it is acceptable and feasible to engage people with psychosis in a brief imagery-based metacognitive intervention and that positive change can be achieved. Further studies are needed to replicate and clarify the findings of our study and develop the evidence base for this intervention.
Personalized high-definition transcranial direct current stimulation improves cognition following carbon monoxide poisoning induced amnesia: A case report
Authors: Schneider Brett S , McInnis Melvin , Di Rita Victor , Hampstead Benjamin M 
Published: December 2024

AbstractObjective:High-definition transcranial direct current stimulation (HD-tDCS) has the potential to improve cognitive functioning following neurological injury and in neurodegenerative conditions. In this case report, we present the first use of HD-tDCS in a person with severe anterograde amnesia following carbon monoxide poisoning.Method:The participant underwent two rounds of HD-tDCS that were separated by 3 months (Round 1 = 30 sessions; Round 2 = 31 sessions). We used finite element modeling of the participant’s structural MRI to develop an individualized montage that targeted multiple brain regions involved in memory encoding, as identified by Neurosynth.Results:Overall, the participant’s objective cognitive functioning improved significantly following Round 1, declined during the 2 months without HD-tDCS, and again improved following Round 2. Subjective informant reports from family and medical personnel followed this same pattern of improvement following each round with a decline in between rounds. We also provide preliminary evidence of altered brain activity during a learning/memory task using functional near-infrared spectroscopy, which may help establish the physiological effects of HD-tDCS in future work.Conclusion:Overall, these findings reinforce the potential value of HD-tDCS as a user-friendly method of enhancing cognition following anoxic/hypoxic brain injury.
Sufficient mathematical conditions for identical estimation of the liability for remaining coverage under the general measurement model and premium allocation approach
Authors: Lee Timothy , Jagga Antonie 
Published: December 2024

Abstract
Paragraph 53(a) of the new insurance accounting standard IFRS 17 suggests there is a relationship between the liability for remaining coverage (“LFRC”) calculated under the general measurement model (“GMM”) and premium allocation approach (“PAA”), although it is not immediately obvious how the two are related or could result in a similar estimate for the LFRC. This paper explores the underlying relationship between the GMM and PAA through the equivalence principle and presents a set of sufficient mathematical conditions that result in an identical LFRC when calculated under the GMM and PAA. An illustrative example is included to demonstrate how the sufficient conditions can be applied in practice and the optimisation opportunities offered to actuaries and accountants when conducting PAA eligibility testing.
Institutional design in commons-based sharing economies: platform, care and place
Authors: Morgan Bronwen 
Published: December 2024

AbstractThis paper presents an analytical mapping of institutional design possibilities for alternative ways for digital platforms to institutionalise property and corporate form. It builds on the institutional imagination catalysed by three vignettes of experimental sharing economy initiatives presented towards the start of the paper, each of which highlights the imbrication and interdependence between economic and social dimensions of the sharing economy. The paper then interrogates the vignettes through three analytical entry points to the institutional design of commons-based sharing economies: platform, care and place. By remapping the vignettes’ practices around these three entry points, the paper shows how they help constitute the incipient formalisation of commons-based approaches to the sharing economy. The prospects for carrying out a redesign of property and corporate forms more generally thereby become more visible, providing a sound foundation for more in-depth empirical and historical work on alternative trajectories of the sharing economy in the future.
Evidence of Potential Thermospheric Overcooling During the May 2024 Geomagnetic Superstorm

Published: December 2024

Abstract[During intense geomagnetic storms, the rapid and significant production of nitric oxide (NO) followed by its associated infrared radiative emission in lower thermosphere contributes crucially to the energetics of the upper atmosphere. This makes NO infrared radiative cooling a very important phenomenon which needs to be considered for accurate density forecasting in thermosphere. This study reports the investigation of variations in thermospheric density, and NO radiative cooling during the recent geomagnetic superstorm of May 2024. A very rare post‐storm thermospheric density depletion of about −23% on May 12 was observed by Swarm‐C in northern hemisphere in comparison to the prestorm condition on May 9. This overcooling was observed despite the continuous enhancement in solar EUV (24–36 nm) flux throughout the event. The thermospheric NO infrared radiative emission in the recovery phase of the storm is likely to be the plausible cause for this observed post‐storm density depletion. Our analysis also suggests an all time high thermospheric NO radiative cooling flux up to 11.84 /sec during May 2024 geomagnetic superstorm, which has also been compared with famous Halloween storms of October 2003].

AbstractAging is accompanied by possible cognitive impairment, as well as a reduction in nitric oxide (NO) bioavailability, insulin resistance, and vitamin D deficiency. Among these Nitric oxide exhibits a dual role in brain biology, where both low and high levels can have detrimental effects on memory and neurotoxicity. In this study we aimed to investigate the role of nitric oxide, insulin resistance, and vitamin D in cognitive function of elderly individuals. This case-control study involved participants aged ≥ 60 years who were under observation in the Birjand Longitudinal Aging Study. A total of 40 participants were selected as controls, while 64 participants with cognitive impairment were identified as cases. The cases were further subdivided according to their Mini-Mental State Examination (MMSE) scores into two groups: mild and moderate cognitive impairment. Cognitive function in both cases and controls was assessed using the MMSE. The levels of total NOx, vitamin D, insulin, and blood glucose were measured using ELISA and spectrophotometric immunoassays. Insulin resistance indices, such as homeostasis model assessment of insulin resistance (HOMA-IR) and quantitative insulin sensitivity check index (QUICKI) were calculated. Serum NOx levels were significantly lower in participants with cognitive impairment compared to the control group (p < 0.01). However, the mean (SD) levels of serum vitamin D, insulin, and glucose, as well as the insulin resistance markers, showed no significant differences between the groups. A positive correlation was observed between serum NOx levels and MMSE scores. NO may be an essential factor for normal brain function, as serum NOx levels were significantly higher in controls compared to those with cognitive impairment, and there was a positive correlation with MMSE scores. Other metabolic and nutritional markers, including vitamin D and insulin resistance, did not demonstrate a significant effect.

AbstractDespite the development of cancer biomarkers and targeted therapies, most cancer patients do not have a specific biomarker directly associated with effective treatment options. We have developed VT1021 that induces the expression of thrombospondin-1 (TSP-1) in myeloid-derived suppressor cells (MDSCs) recruited to the tumor microenvironment (TME). Our studies identified CD36 and CD47 as dual biomarkers that can be used as patient stratifying tools and prognostic biomarkers for VT1021 treatment.
Recorded Word Recognition Testing Is Worth the Time
Authors: Austin Allie , Ladner Kathryn , Mendel Lisa Lucks 
Published: December 2024

Purpose:
The goal of this study was to provide evidence of the inherent variability associated with monitored live voice (MLV) presentation methods and encourage audiologists to more closely follow best practice of using recorded stimuli. To accomplish the goal, administration times for word recognition testing were compared between MLV and MP3 recorded stimuli presented directly from an audiometer (computer assisted, CA). Furthermore, the variability of administration time across testers was evaluated.

Method:
Fifty-word NU-6 lists were presented via MLV and CA to listeners with typical hearing (TH; defined as a four-frequency [500, 1000, 2000, and 4000 Hz] pure-tone average [PTA] of 20 dB HL or better) and hearing loss (HL; defined as a four-frequency PTA poorer than 20 dB HL). Audiologists and doctor of audiology students administered the word lists. Administration times were compared between the two presentation methods (MLV and CA).

Results:
MLV administration time was significantly shorter than CA presentation time for both the TH and HL groups. There was also a significant difference in word recognition scores (WRS) between the TH and HL groups only when using the CA method. Most notably, there was significantly more variability in the administration time for MLV presentation across testers compared to the CA method. Data were compared to Mendel and Owen (2011), and MLV administration time was found to be significantly shorter than CA and compact disk (CD) administration time.

Conclusions:
Despite the shorter average administration time for MLV presentation compared to CA or CD, the significant variability in administration time among individual testers limits the clinical value of the test results. In addition, WRS for those with hearing loss were significantly poorer than those with TH when using CA but not for MLV, indicating that MLV is not sensitive to the presence of sensorineural hearing loss. Thus, using recorded word recognition is strongly recommended.
Analysis of the influence of configuration parameters on the electric field distribution of the main insulation structure of valve‐side winding of converter transformer considering electro‐thermal coupling

Published: December 2024

AbstractThe variation of configuration parameters in the insulation structure of transformers significantly impacts the distribution of electric fields. Current research on electric field distribution calculations often overlooks the influence of electric field intensity and temperature on this distribution. However, considering that the direct current conductivity of oil‐paper materials is easily affected by both electric field intensity and temperature, any changes in their conductivity will inevitably affect the electric field distribution. Therefore, this paper incorporates the influence of electric field intensity and temperature on the calculation process of the electric field distribution in the main insulation structure of the valve‐side winding. Additionally, it calculates the distribution of multi‐fields for a wide range of structural configuration parameters. Consequently, the influence law of insulation structure configuration parameters on the electric field distribution of the main insulation structure of valve‐side winding for converter transformer when considering electro‐thermal coupling is obtained. This finding can serve as a crucial reference for designing and optimising converter transformers.
Chance‐constrained scheduling considering frequency support from electric vehicles under multiple uncertainties

Published: December 2024

AbstractWith the share of renewable generation increasing, considerable synchronous generators have been displaced. This trend results in the decline of system inertia and thus raises the frequency secure issue. Concurrently, electric vehicles (EVs) proliferate. Numerous EVs hold a huge potential of frequency regulation in case of contingency as EVs are able to achieve primary frequency responses (PFRs) via vehicle to grid chargers. However, the value of frequency responses from aggregated EVs has not fully exploited. This paper, proposes a chance constrained scheduling model incorporating the ability of PFRs from aggregated EVs. The proposed model characterizes uncertainties associated PFR capacities from aggregated EVs and wind power forecast errors by the Wasserstein‐metric ambiguity sets, which do not rely on distributional assumption, and then formulates uncertainties‐related constraints as distributionally robust (DR) chance constraints. These DR chance constraints are reformulated as tractable linear programs. Consequently, the proposed model leads to a mixed‐integer linear program. Numerical results on a modified IEEE 39‐bus system show that incorporating PFR from EVs can reduce total costs from $4,540,396 to $4,431,233, which is reduced by 2.4%. The proposed model also achieves better reliability compared to traditional methods, demonstrating the distributionally robust optimization in enhancing electricity scheduling and rising renewable integration.
Numerical investigation of instabilities in over-pressured magnetized relativistic jets
Authors: Hu Xu-Fan , Mizuno Yosuke , Fromm Christian M. 
Published: December 2024

Context. Relativistic jets from active galactic nuclei are observed to be collimated on the parsec scale. When the pressure between the jet and the ambient medium is mismatched, recollimation shocks and rarefaction shocks are formed. Previous numerical simulations have shown that instabilities can destroy the recollimation structure of jets.
Aims. In this study, we aim to study the instabilities of nonequilibrium over-pressured relativistic jets with helical magnetic fields. Especially, we investigate how the magnetic pitch affects the development of instabilities.
Methods. We performed 3D relativistic magnetohydrodynamic simulations for different magnetic pitches, as well as a 2D simulation and a relativistic hydrodynamic simulation which served as comparison groups.
Results. In our simulations, Rayleigh-Taylor instability (RTI) is triggered at the interface between the jet and ambient medium in the recollimation structure of the jet. We find that when the magnetic pitch decreases, the growth of RTI becomes weak but, interestingly, another instability – the current-driven (CD) kink instability – is excited. The excitement of CD kink instability after passing the recollimation shocks can match the explanation of the quasi-periodic oscillations observed in BL Lac qualitatively.

Objective We aimed to evaluate the relationship between intrapartum continuous glucose monitoring (CGM) and neonatal hypoglycemia (NH) in individuals with diabetes.
Study Design a multicenter prospective study (November 2021–December 2022) of laboring individuals with pregestational or gestational diabetes at ≥34 weeks. Cohorts had a blinded CGM placed from admission through delivery and were monitored with fingerstick (FS) according to usual care. The primary outcome was NH. Secondary neonatal outcomes included neonatal intensive care unit (NICU) length of stay, need for intravenous (IV) glucose therapy, hyperbilirubinemia, respiratory distress, or respiratory distress syndrome. Time in the target range (TIR; range 70–110 mg/dL) and time above the target range (TAR; >110 mg/dL) were expressed as a percentage of all CGM readings, and mean glucose was obtained. Youden index was used to choose the cut point for TAR and prediction of NH.
Results Of 9,479 deliveries during the study period, 202 (2.1%) met the inclusion criteria, and 112 (56%) participants were enrolled (n = 7 did not have available CGM data). Of the study participants, 45 (40%) had pregestational diabetes, and 67 (60%) had gestational diabetes. The mean glucose in labor using a CGM was 102.6 mg/dL (interquartile range [IQR]:89.9, 113.5 mg/dL), and the average percentage of TIR was 62.1% (IQR, 36.9, 85.6). CGM and FS were poor predictors of NH, with no differences in area under the curve (AUC) of mean glucose as a predictor (0.64, 95% CI: 0.48–0.23 vs. 0.53, 95% CI: 0.4–0.6, respectively). The best cut-off for the prediction of NH was a TAR of 61%, with 23% (n = 24) being above the threshold. The rate of NH for TAR >61% versus ≤61% was 45.8 versus 25.9% (p = 0.06). Neonates born to individuals with TAR >61% were more likely to require continuous positive airway pressure after delivery and had a higher cord c-peptide level.
Conclusion In this prospective study of laboring individuals with diabetes, intrapartum CGM TAR was associated with a higher rate of NH.

Switching, amplifying, and chirping diode lasers with current pulses for high bandwidth quantum technologies
Authors: Buser Gianni 
Published: December 2024

A series of simple and low-cost devices for switching, amplifying, and chirping diode lasers based on current modulation are presented. Direct modulation of diode laser currents is rarely sufficient to establish precise amplitude and phase control over light, as its effects on these parameters are not independent. These devices overcome this limitation by exploiting amplifier saturation and dramatically outperform commonly used external modulators in key figures of merit for quantum technological applications. Semiconductor optical amplifiers operated on either rubidium D line are recast as intensity switches and shown to achieve ON:OFF ratios &gt;106 in as little as 50 ns. Current is switched to a 795 nm wavelength (Rb D1) tapered amplifier to produce optical pulses of few nanosecond duration and peak powers of 3 W at a similar extinction ratio. Fast rf pulses are applied directly to a laser diode to shift its emission frequency by up to 300 MHz in either direction and at a maximum chirp rate of 150 MHz ns−1. Finally, the latter components are combined, yielding a system that produces watt-level optical pulses with arbitrary frequency chirps in the given range and &lt;2% residual intensity variation, all within 65 ns upon asynchronous demand. Such systems have broad application in atomic, molecular, and optical physics and are of particular interest to fast experiments simultaneously requiring high power and low noise, for example, quantum memory experiments with atomic vapors.
