Abstract
Background
The Cluster Headache Impact Questionnaire (CHIQ) is a specific and easy-to-use questionnaire to assess the current impact of cluster headache (CH). The aim of this study was to validate the Italian version of the CHIQ.

Methods
We included patients diagnosed with episodic CH (eCH) or chronic CH (cCH) according to the ICHD-3 criteria and included in the “Italian Headache Registry” (RICe). The questionnaire was administered to patients through an electronic form in two sessions: at first visit for validation, and after 7 days for test-retest reliability. For internal consistency, Cronbach’s alpha was calculated. Convergent validity of the CHIQ with CH features and the results of questionnaires assessing anxiety, depression, stress, and quality of life was evaluated using Spearman’s correlation coefficient.

Results
We included 181 patients subdivided in 96 patients with active eCH, 14 with cCH, and 71 with eCH in remission. The 110 patients with either active eCH or cCH were included in the validation cohort; only 24 patients with CH were characterized by a stable attack frequency after 7 days, and were included in the test-retest cohort. Internal consistency of the CHIQ was good with a Cronbach alpha value of 0.891. The CHIQ score showed a significant positive correlation with anxiety, depression, and stress scores, while showing a significant negative correlation with quality-of-life scale scores.

Conclusion
Our data show the validity of the Italian version of the CHIQ, which represents a suitable tool for evaluating the social and psychological impact of CH in clinical practice and research.

AbstractΤhis paper proposed a sustainable treatment scheme for effluents from fruit and vegetable processing industries with high organic load that combined heterotrophic microalgae cultivation with microalgae spray drying producing end-products of commercial interest (biofertilisers and/or animal feed). A pilot plant was operated with feedstock from a fruit and vegetable processing industry and its final products were assessed. The pilot plant was powered by renewable energy (solar energy supported by biomass), which minimized the carbon footprint and operating costs of the process. Through the ultimate analysis of the produced algae, it was evident that in all cases it could be commercialized as a solid NPK organic fertilizer being in line with the respective EU and Spanish legislation framework. As far as the animal feed perspective is concerned, the end-product of the pilot plant could be efficiently included in the feed of various animals, substituting a significant part of the animal feed required. The results from the implementation were used for the design of a full-scale implementation of the innovative treatment scheme, proving that 1.26 ton/d of microalgae could be produced, which could be later used as fertiliser and/or animal feed from the daily wastewater production of a medium sized fruit and vegetable processing company. From an environmental perspective, the proposed solution provides a gold standard example of the circular economy concept, since 1.15 kg CO2 equivalent per kg of sludge avoided could be saved. Additionally, the use of renewable energy (solar and biomass) will result in a saving of 0.531 kg of CO2 emissions per kWh consumed. Conclusively, the proposed treatment scheme could meet circularity and sustainability since the end-products quality permits their integration into new value chains.

AbstractThis research builds upon the extensive body of work to model exotic annual grass (EAG) characteristics and invasion. EAGs increase wildland fire risk and intensifies wildland fire behavior in western U.S. rangelands. Therefore, understanding characteristics of EAG growth increases understanding of its dynamics and can inform rangeland management decisions. To better understand EAG phenology and spatial distribution, monthly weather (precipitation, minimum and maximum temperature) variables were analyzed for 24 level III ecoregions. This research characterizes EAGs’ phenology identified by a normalized difference vegetation index (NDVI) threshold-based interpolation technique. An EAG phenology metric model was used to estimate a growing season dynamic for the years 2017–2021 for shrub and herbaceous land cover types in the western conterminous United States (66% of the area). The EAG phenology metrics include six growing season metrics such as start of season time, end of season time, and time of maximum NDVI during the growing season. The models’ cross validation results for Pearson’s r ranged from 0.88 to 0.95. Increased understanding of the effects that weather conditions have on EAG growth and spatial distribution can help land managers develop time-sensitive plans to protect entities deemed valuable to society like native habitat, wildlife, recreational areas, and air quality.

Published: March 2023

AbstractBackground: EEG-fMRI is a useful additional test to localize the epileptogenic zone (EZ) particularly in MRI negative cases. However subject motion presents a particular challenge owing to its large effects on both MRI and EEG signal. Traditionally it is assumed that prospective motion correction (PMC) of fMRI precludes EEG artifact correction. Methods: Children undergoing presurgical assessment at Great Ormond Street Hospital were included into the study. PMC of fMRI was done using a commercial system with a Moiré Phase Tracking marker and MR-compatible camera. For retrospective EEG correction both a standard and a motion educated EEG artefact correction (REEGMAS) were compared to each other. Results: Ten children underwent simultaneous EEG-fMRI. Overall head movement was high (mean RMS velocity < 1.5 mm/s) and showed high inter- and intra-individual variability. Comparing motion measured by the PMC camera and the (uncorrected residual) motion detected by realignment of fMRI images, there was a five-fold reduction in motion from its prospective correction. Retrospective EEG correction using both standard approaches and REEGMAS allowed the visualization and identification of physiological noise and epileptiform discharges. Seven of 10 children had significant maps, which were concordant with the clinical EZ hypothesis in 6 of these 7. Conclusion: To our knowledge this is the first application of camera-based PMC for MRI in a pediatric clinical setting. Despite large amount of movement PMC in combination with retrospective EEG correction recovered data and obtained clinically meaningful results during high levels of subject motion. Practical limitations may currently limit the widespread use of this technology.
Game Theory and Demonstratives
Authors: Smit J. P. 
Published: March 2023

AbstractThis paper argues, based on Lewis’ claim that communication is a coordination game (Lewis in Minnesota studies in the philosophy of science, University of Minnesota Press, Minneapolis, pp 3–35, 1975), that we can account for the communicative function of demonstratives without assuming that they semantically refer. The appeal of such a game theoretical version of the case for non-referentialism is that the communicative role of demonstratives can be accounted for without entering the cul de sac of trying to construct conventions of ever-increasing complexity. Instead communication via demonstratives is explained with reference to the general, non-domain specific ability of human beings to solve games of coordination. Furthermore, there is empirical support for such a view. Judgments concerning demonstrative reference have been shown to be sensitive to judgments concerning common ground (Clark et al. in J Verb Learn Verb Behav 22:245–258, 1983), which is exactly what the non-referentialist account would predict. The game theoretical account also allows for an intuitively plausible, non-referentialist treatment of Speaks’ ‘trumping argument’ (Speaks in Philos Stud 174:709–734, 2017), as well as the Carnap/Agnew puzzle (Kaplan in Syntax Semant 9:221–43, 1970).

AbstractPurpose: The Cognitive Symptom Checklist-Work (CSC-W) is a self-report measure to assess cognitive symptoms (i.e., memory and executive function) in working adults with cancer. To date, general working population norm data are lacking worldwide. We established CSC-W norm values in the general working population, and assessed associations of CSC-W scores with work and health-related factors. Methods: This cross-sectional study consisted of 1,000 Dutch working adults, of whom data was collected through an online respondent panel. The sample was stratified for sex and age, and data were weighted. Summary scores of the CSC-W total scale, and memory and executive function symptoms subscales, were determined (e.g., means, percentiles). Z- and T-scores were calculated, and analysis of (co)variance has been applied. Results: Cognitive symptom scores were relatively stable across age groups, but 18-39-year-old respondents reported lower memory and executive function than respondents in other age groups. Symptom scores of memory function (mean 29.1; SD = 16.7) were higher for all age groups and in both sexes compared to executive function (mean 22.1; SD = 16.8). No sex differences in memory and executive function were observed. Higher symptom scores were associated with performing non-manual work only, manual work only, self-reported long-term illness, and higher levels of depressive symptoms and fatigue. Conclusion: The CSC-W norms may enhance the interpretation and facilitate the analysis of self-reported cognitive symptoms in patients with cancer at work. Our findings may support health care professionals in identifying working adults with cancer with cognitive symptoms and in developing personalized treatment.
An Exact Solution Algorithm for Integer Bilevel Programming with Application in Energy Market Optimization
Authors: Kozanidis George , Kostarelou Eftychia 
Published: March 2023

AbstractWe develop an exact cutting plane solution algorithm for a special class of bilevel programming models utilized for optimal price-bidding of energy producers in day-ahead electricity markets. The proposed methodology utilizes a suitable reformulation in which a key prerequisite for global optimality, termed bilevel feasibility, is relaxed. Solving the problem to global optimality involves finding the price-offers of the strategic producer (upper-level decision variables) which maximize his self-profit upon clearing of the market and identification of the optimal energy quantity distribution (lower-level decision variables). To exclude from consideration the encountered bilevel infeasible solutions, the algorithm employs a special type of valid cuts drawn from the theory of integer parametric programming. The generation of these cuts involves finding the truly optimal lower-level solution using the strategic price-offers at the bilevel infeasible solution subject to exclusion and devising range intervals for these offers such that the optimality of this solution is retained when each of them lies in its corresponding interval. Each cut imposes a suitable part of this solution, under the condition that each price-offer belongs to its associated interval, which renders the bilevel infeasible solution invalid. We establish the theoretical framework for the development of the proposed algorithm, we illustrate its application on a small case study, and we present extensive computational results demonstrating its behavior and performance on random problem instances. These results indicate that the algorithm is capable of solving to global optimality considerably larger problems than those that a previous elementary version of the same algorithm could solve. This constitutes significant research contribution, considering the lack of generic optimization software for bilevel programming, as well as the fact that the applicability of specialized algorithms on problems of realistic size is rather limited.
A Comparative Study of Treatment Methods of Raw Sugarcane Bagasse for Adsorption of Oil and Diesel

Abstract
Current environmental trends show an increase in pollutant concentrations in water bodies. The alarming concern this poses has made it crucial to remove pollutants from water and eliminate them, owing to the host of issues they cause to the ecosystem. While sorption is a popular method of treating wastewater, there are several concerns regarding its accessibility, affordability, efficiency, and functioning toward a circular sustainable economy. The current study focuses on the feasibility of using sugarcane bagasse (SCB) to remove oil and diesel from water and proposes to do so without turning SCB into biochar, contrary to the usual method. Raw SCB was chemically treated using sodium hydroxide and acetic acid. With little pre-treatment, it was found to have improved sorption abilities with low input materials and environmental toxicity. Sorption experiments conducted on treated and untreated SCB showed the effects of different parameters on the oil or diesel removal efficiency. Furthermore, FTIR, BET, and SEM studies were conducted to characterize the intrinsic morphology and structure of the sorbent.
Emotional design of pedagogical agents: the influence of enthusiasm and model-observer similarity
Authors: Beege Maik , Schneider Sascha 
Published: March 2023

AbstractPedagogical agents were found to enhance learning but studies on the emotional effects of such agents are still missing. While first results show that pedagogical agents with an emotionally positive design might especially foster learning, these findings might depend on the gender of the agent and the learner. This study investigated whether emotional expressions performed by an on-screen instructor were able to increase learning outcomes while considering differences the gender of the agent and the learner. In a 2 (neutral vs. enthusiastic expressions) × 2 (female vs. male agent) between-subject design with additional consideration of the gender of the learner, data of 129 participants was collected. Results revealed that the manipulation of enthusiasm lead to higher perceptions of positive emotions. In addition, a pedagogical agent who performed enthusiastic expressions led to a higher retention but not transfer performance. In terms of the gender of the agent and the learner, male learners retained knowledge better when they watched the agent performing enthusiastic expression irrespective of the persona gender. Female learners, however, retained knowledge only better when a female agent performed enthusiastic expressions. Results are discussed in the light of the positivity principle, model-observer similarity hypotheses and current theories on social cues in multimedia learning.
Michigan Market Referral Coordination Initiative: a Regional Market Approach to VA Specialty Care
Authors: Cusick Alice , Gronek Julie , Gorman Mary , Hausman Mark S. , Schildhouse Richard J. 
Published: March 2023

Abstract
Background
The Maintaining Internal Systems and Integrated Outside Networks (MISSION) Act of 2018 was created in response to reports of prolonged wait times for veterans accessing health care within the Veterans Affairs (VA) system. In Michigan, the MISSION Act Community Care Program led to an increased number of veterans receiving specialty care outside the VA system, in part due to the complicated process of coordinating specialty care within the VA system. From 2018 to 2020, the percentage of veterans referred to the VA Ann Arbor Healthcare System (AA) for specialty care from its two referring facilities, Battle Creek VA Medical Center (BC) and Saginaw VA Healthcare System (SAG), decreased from 54.4 to 27%.

Objective
Improve the number of Michigan veterans choosing VA specialty care.

Intervention
In 2021, three VA facilities in Michigan (AA, BC, and SAG) created a market-level referral system named the Michigan Market Referral Initiative (MMRCI). This unique approach used a centralized nurse-driven team to manage specialty referrals, working directly with the veteran to explore both VA and community care (CC) options.

Main Measures
Referrals triaged and acceptance rates for VA care were tracked. The localized Standard Episode of Care model was used to estimate cost savings. Post-intervention AA patient wait times were compared to local CC wait times.

Key Results
In the 14 months after implementation of the MMRCI, the rate of veteran retention increased by 32.4%. The estimated dollars retained within the VA by MMRCI efforts was $24,105,251 as of 7/1/2022. Post-intervention AA wait times were superior to community care except in 3 specialties.

Conclusions
This multifacility effort is an example of a highly coordinated, veteran-centered collaboration that has led to successful retention of veterans within the VA system with resultant large-scale cost avoidance and comparable clinic wait times. Focusing on central care coordination and veteran engagement in the referral process are keys to its success, along with leveraging existing referral patterns between nearby VA facilities. This model could be extrapolated to other VA markets throughout the country where similar relationships exist.
Racial-Ethnic Composition of Primary Care Practices and Comprehensive Primary Care Plus Initiative Participation
Authors: Rubio Karl , Fraze Taressa K. , Bibi Salma , Rodriguez Hector P. 
Published: March 2023

Abstract
Background

It remains unclear whether the racial-ethnic composition or the socioeconomic profiles of eligible primary care practices better explain practice participation in the Centers for Medicare and Medicaid Services’ (CMS) Comprehensive Primary Care Plus (CPC+) program.

Objective
To examine whether practices serving high proportions of Black or Latino Medicare fee-for-service (FFS) beneficiaries were less likely to participate in CPC+ in 2021 compared to practices serving lower proportions of these populations.

Design
2019 IQVIA OneKey data on practice characteristics was linked with 2018 CMS claims data and 2021 CMS CPC+ participation data. Medicare FFS beneficiaries were attributed to practices using CMS’s primary care attribution method.

Participants
11,718 primary care practices and 7,264,812 attributed Medicare FFS beneficiaries across 18 eligible regions.

Methods
Multivariable logistic regression models examined whether eligible practices with relatively high shares of Black or Latino Medicare FFS beneficiaries were less likely to participate in CPC+ in 2021, controlling for the clinical and socioeconomic profiles of practices.

Main Measures
Proportion of Medicare FFS beneficiaries attributed to each practice that are (1) Latino and (2) Black.

Key Results
Of the eligible practices, 26.9% were CPC+ participants. In adjusted analyses, practices with relatively high shares of Black (adjusted odds ratio, aOR = 0.62, p < 0.05) and Latino (aOR = 0.32, p < 0.01) beneficiaries were less likely to participate in CPC+ compared to practices with lower shares of these beneficiary groups. State differences in CPC+ participation rates partially explained participation disparities for practices with relatively high shares of Black beneficiaries, but did not explain participation disparities for practices with relatively high shares of Latino beneficiaries.

Conclusions
The racial-ethnic composition of eligible primary care practices is more strongly associated with CPC+ participation than census tract–level poverty. Practice eligibility requirements for CMS-sponsored initiatives should be reconsidered so that Black and Latino beneficiaries are not left out of the benefits of practice transformation.

Published: March 2023

AbstractWith the raw materials for ironmaking are becoming increasingly complex, more accurate control of blast furnace operation is essential to reduce the energy cost and CO2 emission. CaO–SiO2–Al2O3–MgO is a basic system of ironmaking slag in which CaO and MgO are mainly come from the flux, SiO2 and Al2O3 are mainly from the raw materials. Effect of raw material composition on phase equilibrium of the slag can be described by a pseudo-ternary system (CaO + MgO)–SiO2–Al2O3 at a fixed MgO/CaO ratio of 0.2. High-temperature experiments have been carried out in this system, and the quenched samples were analyzed by an electron-probe microanalyzer. The results are presented in a pseudo-ternary phase diagram (CaO + MgO)–SiO2–Al2O3 with a fixed MgO/CaO weight ratio of 0.2. Dicalcium silicate (Ca2SiO4), Melilite (2CaO·MgO·2SiO2–2CaO·Al2O3·SiO2), spinel (MgO·Al2O3), merwinite (3CaO·MgO·2SiO2), and anorthite (CaO·Al2O3·2SiO2) are the major primary phases in the composition range investigated. A series of pseudo-binary phase diagrams have been constructed to demonstrate the applications of phase diagram on blast furnace operation. CaO-rich cordierite solid solution has been first time reported with the accurate compositions and microstructure. The liquidus temperatures and solid solution compositions are compared between the experimental data and FactSage predictions to provide useful information for optimization of the thermodynamic database.
