Published: July 2023

Abstract
Jets and their substructure play a central role in many analyses at the Large Hadron Collider (LHC). To improve the precision of measurements, as well as to enable measurement of jet substructure at increasingly small angular scales, tracking information is often used due to its superior angular resolution and robustness to pile-up. Calculations of track-based observables involve non-perturbative track functions, that absorb infrared divergences in perturbative calculations and describe the transition to charged hadrons. The infrared divergences are directly related to the renormalization group evolution (RGE), and can be systematically computed in perturbation theory. Unlike the standard DGLAP evolution, the RGE of the track functions is non-linear, encoding correlations in the fragmentation process. We compute the next-to-leading order (NLO) evolution of the track functions, which involves in its kernel the full 1 → 3 splitting function. We discuss in detail how we implement the evolution equation numerically, and illustrate the size of the NLO corrections. We also show that our equation can be viewed as a master equation for collinear evolution at NLO, by illustrating that by integrating out specific terms, one can derive the evolution for any N -hadron fragmentation function. Our results provide a crucial ingredient for obtaining track-based predictions for generic measurements at the LHC, and for improving the description of the collinear dynamics of jets.

Abstract
We explore the prospects of constraining general non standard interactions involving light mediators through elastic neutrino-electron scattering events at the DUNE Near Detector (ND). We furthermore consider the special cases of light vector mediators in motivated models such as U(1)B−L, $$ \textrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$

The present analysis is based on detailed Monte Carlo simulations of the expected DUNE-ND signal taking into account detector resolution effects, realistic backgrounds as well as On-Axis and Off-Axis neutrino spectra. We show that the high intensity neutrino beam available at Fermilab can place competitive constraints surpassing those of low-energy neutrino searches and direct detection dark matter experiments.

Abstract
Rationale
Working memory deficits and associated neurofunctional abnormalities are frequently reported in attention-deficit/hyperactivity disorder (ADHD). Methylphenidate and atomoxetine improve working memory performance and increase activation of regions under-functioning in ADHD. Additionally, methylphenidate has been observed to modulate functional networks involved in working memory. No research, however, has examined the effects of atomoxetine or compared the two drugs.

Objectives
This study aimed to test methylphenidate and atomoxetine effects on functional connectivity during working memory in boys with ADHD.

Methods
We tested comparative effects of methylphenidate and atomoxetine on functional connectivity during the n-back task in 19 medication-naïve boys with ADHD (10–15 years old) relative to placebo and assessed potential normalisation effects of brain dysfunctions under placebo relative to 20 age-matched neurotypical boys. Patients were scanned in a randomised, double-blind, cross-over design under single doses of methylphenidate, atomoxetine, and placebo. Controls were scanned once, unmedicated.

Results
Patients under placebo showed abnormally increased connectivity between right superior parietal gyrus (rSPG) and left central operculum/insula. This hyperconnectivity was not observed when patients were under methylphenidate or atomoxetine. Furthermore, under methylphenidate, patients showed increased connectivity relative to controls between right middle frontal gyrus (rMFG) and cingulo-temporo-parietal and striato-thalamic regions, and between rSPG and cingulo-parietal areas. Interrogating these networks within patients revealed increased connectivity between both rMFG and rSPG and right supramarginal gyrus under methylphenidate relative to placebo. Nonetheless, no differences across drug conditions were observed within patients at whole brain level. No drug effects on performance were observed.

Conclusions
This study shows shared modulating effects of methylphenidate and atomoxetine on parieto-insular connectivity but exclusive effects of methylphenidate on connectivity increases in fronto-temporo-parietal and fronto-striato-thalamic networks in ADHD.
Thickness of zero-strength layer in timber beam exposed to fuel-controlled parametric fires
Authors: Huč Sabina , Hozjan Tomaž , Pečenko Robert 
Published: July 2023

AbstractFire resistance is one of the essential requirements to be fulfilled in the design of timber structures. For this purpose, a reduced cross-section method is given in the European standards, Eurocodes. The method is based on the assumption that an initial, rectangular timber cross-section exposed to fire conditions reduces to an effective cross-section, which has material properties as at a room temperature. The reduced part of the cross-section with no resistance is determined by a sum of two parameters, namely a charring depth and a thickness of zero-strength layer. Eurocodes give a value of the latter only for the standard fire exposure, which is only one of the fire curves proposed in the same standards. Therefore, the present paper examines the thickness of zero-strength layer in case of 46 different fuel-controlled parametric fire exposures applied to a timber beam from three sides. A four-phase numerical analysis is applied for this purpose that includes the use of a hygro-thermal model and a mechanical model to determine temperatures of timber over the cross-section and the mechanical resistance of timber beam in fire conditions, respectively. The results show that the thickness of zero-strength layer takes the values between 7.9 and 18.4 mm for the fuel-controlled parametric fire exposures. Since it is clearly dependent on the parameters describing the parametric fire curve, five equations are proposed that can be used for determination of the thickness of zero-strength layer in case of parametric fire exposures.
Corporate Engagement Strategies in Northern Mining: Boliden, Sweden and Cameco, Canada
Authors: Poelzer Gregory 
Published: July 2023

AbstractThe role of corporations in societal outcomes continues to grow. Mining companies now face the expectation of not only providing economic benefits to communities, but act as a facilitator for social wellbeing and environmental stewardship. In the mining sector, this has placed renewed attention to defining corporate social responsibility and, in turn, how social license to operate is understood. These developments are particularly pertinent when mining operations affect Indigenous communities – where land use is central to livelihood. This study looks at the community engagement strategies of two mining companies in northern countries, Cameco (Canada) and Boliden (Sweden). By comparing their approaches, this paper explores the development of their practices over time and assess to what extent their corporate policy has translated into everyday practice and outcomes. The findings of demonstrate that high levels of trust are established when corporate approaches are built around transparency and collaboration – resulting in agreements that include long-term partnerships around socio-economic and environmental management.

Abstract
The 10th Global Forum for Liver Magnetic Resonance Imaging (MRI) was held as a virtual 2-day meeting in October 2021, attended by delegates from North and South America, Asia, Australia, and Europe. Most delegates were radiologists with experience in liver MRI, with representation also from specialists in liver surgery, oncology, and hepatology.
Presentations, discussions, and working groups at the Forum focused on the following themes:

• Gadoxetic acid in clinical practice: Eastern and Western perspectives on current uses and challenges in hepatocellular carcinoma (HCC) screening/surveillance, diagnosis, and management
• Economics and outcomes of HCC imaging
• Radiomics, artificial intelligence (AI) and deep learning (DL) applications of MRI in HCC.
These themes are the subject of the current manuscript. A second manuscript discusses multidisciplinary tumor board perspectives: how to approach early-, mid-, and late-stage HCC management from the perspectives of a liver surgeon, interventional radiologist, and oncologist (Taouli et al, 2023).
Delegates voted on consensus statements that were developed by working groups on these meeting themes. A consensus was considered to be reached if at least 80% of the voting delegates agreed on the statements.

Clinical relevance statement
This review highlights the clinical applications of gadoxetic acid–enhanced MRI for liver cancer screening and diagnosis, as well as its cost-effectiveness and the applications of radiomics and AI in patients with liver cancer.

Key Points
• Interpretation of gadoxetic acid–enhanced MRI differs slightly between Eastern and Western guidelines, reflecting different regional requirements for sensitivity vs specificity.
• Emerging data are encouraging for the cost-effectiveness of gadoxetic acid–enhanced MRI in HCC screening and diagnosis, but more studies are required.
• Radiomics and artificial intelligence are likely, in the future, to contribute to the detection, staging, assessment of treatment response and prediction of prognosis of HCC—reducing the burden on radiologists and other specialists and supporting timely and targeted treatment for patients.
Effects of temperature on factors relevant to laser operation near 1.6 µm wavelength in resonantly (in-band) pumped CaF2:Er and SrF2:Er crystals: a comparative study

Published: July 2023

AbstractSingle crystals of CaF2 and SrF2 containing Er3+ ions with concentrations between 0.01 and 0.6 at% respectively, were grown using the temperature gradient technique (TGT). Absorption spectra related to the 4I15/2 → 4I13/2 transition of Er3+ ions were measured at 5 K to investigate the properties of the crystal field splitting of the 4I13/2 multiplet, and at several temperatures in the region 80 K – 300 K to determine the effect of temperature on the spectral bands. The 4I13/2 → 4I15/2 luminescence spectra were recorded within the same temperature range as for absorption measurement. The analysis of absorption and luminescence spectra provides an in-depth knowledge on the effect of temperature on the factors that govern the efficiency of resonant optical pumping near 1.6 µm and the resulting lasing ability of Er3+ ions imbedded in CaF2 and SrF2 hosts.

Abstract
Purpose
Radial artery occlusion (RAO) is an unresolved complication after transradial artery (TRA) puncture. The aim of this observational study was to assess the feasibility and safety of retrograde recanalization of RAO through distal transradial access (dTRA).

Methods
From June 2021 to March 2022, 28 consecutive patients with successful puncture and intubation through the dTRA in the anatomical snuffbox and RAO confirmed by angiography were enrolled.

Results
Among the 28 patients, 27 (96.4%) patients with RAO were successfully retrogradely recanalized through the dTRA and successfully underwent coronary angiography or coronary intervention. After the procedure, only 1 (3.7%) patient developed a forearm hematoma, and there were no other bleeding complications or nerve disorders.

Conclusions
DTRA is a safe and feasible approach for retrograded recanalization of RAO, with a high procedure success rate and few complications.
Indirect determination of partial depolymerization reactions in dialdehyde celluloses (DAC) by gel permeation chromatography of their oxime derivatives

Published: July 2023

AbstractOwing to a supposed quantitative transformation, oximation of dialdehyde cellulose (DAC) with hydroxylamine hydrochloride is commonly employed in chemical DAC analysis, e.g., for the determination of the degree of oxidation (DO) by titration or elemental analysis. In this study, this modification was utilized for the indirect determination of molecular weight distributions (MWD) by gel permeation chromatography (GPC). The presumably quantitative conversion of aldehyde groups in DAC to the corresponding oxime also breaks up the intermolecular and intramolecular hemiacetal crosslinks, which were associated with solubility issues in the DMAc/LiCl solvent system in previous studies. The limits of the procedure and the material's stability during oximation were investigated. For samples with a DO up to approximately 9% a good applicability was observed, before at higher DO values residual crosslinks led to solubility problems. The oximation/GPC protocol was used to examine the development of the MWD in the early stages of DAC formation under different reaction conditions. The time-dependent partial depolymerization of the polymer backbone was observed. Furthermore, the stability of DAC towards different pH conditions ranging from strongly acidic to strongly alkaline was tested. The depolymerization of DAC in alkaline media occurred with concomitant degradation of aldehyde moieties. In turn, DAC proved to be remarkably stable in acidic and neutral solutions up to a pH of 7.

AbstractFlutamide (FLU), bicalutamide (BIC), and hydroxyflutamide (OHF), having a low biodegradability, may cause severe health effects on humans as antiandrogens. In this work, we have developed two electrochemical sensors using manganese oxide (MnO) and Cobalt oxide (CoO) nanostructures (NSs) as electrocatalysts. The GCE modified with MnO is referred to as MnO/GCE and the GCE modified by CoO is referred to as CoO/GCE. The electrochemical behaviours of CoO/GCE and MnO/GCE were examined in ferricyanide solution. It was observed through the employment of cyclic voltammetry that MnO/GCE exhibit better electron transfer than CoO/GCE. The calculated surface coverage values, 1.46 x10−9 mol cm−2 and 5.02 x10−9 mol cm−2 of MnO/GCE and CoO/GCE suggest a multilayer of a metal oxide molecule film at the surfaces of glassy carbon electrodes (GCE). FLU, BIC and OHF were detected at a linear range from 32.01 to 50.00 µM. The limits of detection of FLU, BIC and OHF were 18.5, 13.0 and 78.8 µM at MnO/GCE respectively and 18.8, 18.7 and 18.5 µM at CoO/GCE respectively. Both MnO/GCE and CoO/GCE showed good catalytic stability towards detecting FLU and its derivatives. FLU, BIC and OHF were also detected in the presence of interferents for both electrochemical sensors in phosphate buffer solution. Both MnO/GCE and CoO/GCE confirmed good selectivity without cross interference. Some of the health effects associated with FLU, BIC and OHF are liver damage, prostate inflammation, and methamoglobenia. Although FLU, BIC and OHF are detected in low concentration levels in water bodies, their continuous ingestion is a great concern. As far as we know, MnO and CoO NSs have not been used to electrochemically detect FLU, BIC and OHF. Furthermore, OHF has not been detected electrochemically before and there are only a few studies on the electrochemical detection of BIC. Hence, MnO and CoO NSs are used in this study for the first time for an electrochemical sensor fabrication towards the detection of FLU, BIC and OHF.
Race, Prejudice and Support for Racial Justice Countermovements: The Case of “Blue Lives Matter”
Authors: Newman Benjamin J. , Reny Tyler T. , Merolla Jennifer L. 
Published: July 2023

AbstractIn this article, we develop and test three propositions related to the status of a primary counterpoint of the Black Lives Matter (BLM) movement—“Blue Lives Matter” (BlueLM). Employing correlational and causal analyses on a wide array of data, including public opinion, news and social media, internet searches, and merchandise sales, our findings are threefold: first, we offer evidence that Whiteness is associated with attitudinal and behavioral indicators of support for BlueLM; second, we present evidence that support for BlueLM is systematically linked to White racial prejudice; and third, we demonstrate that BlueLM activity is caused by BLM protest following a high-profile police killing of a Black man, which comports with the conceptualization of BlueLM as engaging in a process of “competitive victimhood” against BLM. Together, these findings suggest that BlueLM is a new incarnation of an ongoing history of White countermobilization against organized Black claims-making activity.
Integrating Norms, Knowledge, and Social Ties into the Deterrence Model of Cartels: A Survey Study of Business Executives
Authors: van Stekelenburg Loet , Dijkstra Peter T. , van Steenbergen Elianne F. , Mastop Jessanne , Ellemers Naomi 
Published: July 2023

AbstractWe expand the rational choice theory of crime, as applied to cartels, with three psychological factors—personal norms, social norms and social ties—and knowledge of competition law. Through a survey of Dutch businesses, we find that adding psychological factors substantially increases the explanatory power of the model: All predict attitudes toward future cartel behavior, with personal norms as the strongest (negative) predictor. Better knowledge of competition law relates to stronger deterrence and norms against collusion. We conclude that psychological factors and knowledge of the law are likely necessary to understand and prevent potential cartel behavior.
Familiar transformative experiences
Authors: Randell Petronella 
Published: July 2023

AbstractOn the standard Paulian definition of epistemically transformative experiences (ETE), we can’t know what an ETE is like before we have it. ETEs are new kinds of experiences and, importantly, can’t be imagined—this is why they have a unique ability to teach us what a particular experience is like. Contra Paul, some philosophers (Sharadin, 2015; Wilkenfeld, 2016; Ismael, 2019; Kind, 2020; Daoust, 2021; Cath, 2022) have argued that transformative experiencescanbe imagined. A neglected consequence of this argument is that if transformative experiences can in fact be imagined, then it is unclear how they could be epistemically transformative. What do they teach us if we can imagine what they’re like in advance? I will argue not only that imaginable experiences can be transformative, but that experiences of a kind which an agent is experientially acquainted with can also be transformative. This latter kind of transformative experiences, which I will call familiar transformative experiences, are transformative not because the agent learns what a new kind of experience is like—by definition, they are not new kinds of experiences—but because the transformativeness of the experience is brought out by features of the agent experiencing them. Epistemic transformation in these cases may be explained by facts about the agent’s perspective and social environment, which allow them to appreciate elements of the experience they did not previously.
Looking back to look forward: a systematic review of and research agenda for dynamic managerial capabilities
Authors: Heubeck Tim 
Published: July 2023

AbstractGiven the complexities of today’s hypercompetitive economy and challenges imposed by recent crises, managerial capabilities have become critical for realizing strategic change. Dynamic managerial capability (DMC) theory offers a useful theoretical lens for analyzing how managers make strategic decisions to build and sustain competitive advantages in dynamic environments. Despite receiving less attention than the broader field of dynamic capabilities, the existing body of research has reached a point where a comprehensive synthesis of the current state of knowledge is warranted. Past reviews of DMCs are either outdated or do not comprehensively examine this multifaceted construct, making a review of research highly necessary and timely. This review systematically synthesizes 54 empirical studies on DMCs. It contributes to the literature by systematically synthesizing DMC research and summarizing these findings into a multi-level framework. This review demonstrates that research on DMCs has significantly progressed over the years, for example, through conceptual expansions, new levels of analysis, or methodological advancements. The developed framework provides an overview of the nomological network surrounding DMCs. A systematic historical analysis of research limitations and recommendations offers a rich research agenda for DMCs. These findings guide scholars and managers by overviewing the foundations of DMCs, demonstrating why strong DMCs are critical for achieving sustainable competitive advantage, and how this theory applies to management practice. Altogether, this review presents an up-to-date review of DMC literature by systematically synthesizing its developments—looking back—and pointing to central research opportunities—looking forward.
