Quantum effects on dynamic structure factors in dense magnetized plasmas
Authors: Mondal Tushar , Gregori Gianluca 
Published: January 2024

We extend the classical magnetohydrodynamics formalism to include nonlocal quantum behavior via the phenomenological Bohm potential. We then solve the quantum magnetohydrodynamics equations to obtain a new analytical form of the dynamic structure factor (DSF), a fundamental quantity linking theory and experiments. Our results show that the three-peak structure—one central Rayleigh peak and two Brillouin peaks—of the DSF arising from quantum hydrodynamic fluctuations becomes (in general) a five-peak structure—one central Rayleigh peak and two pairs of peaks associated with fast and slow magnetosonic waves. The Bohm contribution influences the positions and characteristics (height, width, and intensity) of the peaks by introducing three significant modifications: (i) an increase in effective thermal pressure, (ii) a reduction in the adiabatic index, and (iii) an enhancement of effective thermal diffusivity. The multiple DSF peaks enable concurrent measurements of diverse plasma properties, transport coefficients, and thermodynamic parameters in magnetized dense plasmas. The potential for experimental validation of our theory looms large, particularly through future experiments conducted at state-of-the-art laser facilities.

Do intellectual property rights promote foreign direct investment inflows and technological exports in developing and developed countries?
Authors: ALshubiri Faris , Al Ani Mawih Kareem 
Published: January 2024

Purpose
This study aims to analyse the intellectual property rights (INPR), foreign direct investment (FDI) inflows and technological exports of 32 developing and developed countries for the period of 2006–2020.

Design/methodology/approach
Diagnostic tests were used to confirm the panel least squares, fixed effect, random effect, feasible general least squares, dynamic ordinary least squares and fully modified ordinary least squares estimator results as well as to increase the robustness.

Findings
According to the findings for the developing countries, trademark, patent and industrial design applications, each had a significant positive long-run effect on FDI inflows. In addition, there was a significant positive long-run relationship between patent applications and medium- and high-technology exports. Meanwhile, trademark and industrial design applications had a significant negative long-term effect on medium- and high-technology exports. In developed countries, patent and industrial design applications each have a significant negative long-term on medium- and high-technology exports. Furthermore, patent and trademark applications each had a significant negative long-run effect on FDI inflows.

Originality/value
This study contributes significantly to the focus that host countries evaluate the technology gaps between domestic and foreign investors at different industry levels to select the best INPR rules and innovation process by increasing international cooperation. Furthermore, the host countries should follow the structure–conduct–performance paradigm based on analysis of the market structure, strategic firms and industrial dynamics systems.
Aerodynamic force by Lamb vector integrals in unsteady compressible flows
Authors: Minervino Mauro , Tognaccini Renato 
Published: January 2024

Purpose
This study aims to propose an aerodynamic force decomposition which, for the first time, allows for thrust/drag bookkeeping in two-dimensional viscous and unsteady flows. Lamb vector-based far-field methods are used at the scope, and the paper starts with extending recent steady compressible formulas to the unsteady regime.

Design/methodology/approach
Exact vortical force formulas are derived considering inertial or non-inertial frames, viscous or inviscid flows, fixed or moving bodies. Numerical applications to a NACA0012 airfoil oscillating in pure plunging motion are illustrated, considering subsonic and transonic flow regimes. The total force accuracy and sensitivity to the control volume size is first analysed, then the axial force is decomposed and results are compared to the inviscid force (thrust) and to the steady force (drag).

Findings
Two total axial force decompositions in thrust and drag contributions are proposed, providing satisfactory results. An additional force decomposition is also formulated, which is independent of the arbitrary pole appearing in vortical formulas. Numerical inaccuracies encountered in inertial reference frames are eliminated, and the extended formulation also allows obtaining an accurate force prediction in presence of shock waves.

Originality/value
No thrust/drag bookkeeping methodology was actually available for oscillating airfoils in viscous and compressible flows.
Principal's abusive leadership and teachers' intrinsic and extrinsic motivations: the moderating roles of duration of relationship and group size
Authors: Hassan Tahani , Berkovich Izhak 
Published: January 2024

PurposeThis study investigated the relationship between principals' abusive leadership and teachers' intrinsic and extrinsic motivations, exploring the potential moderating effects of the duration of the relationship and group size within educational settings.Design/methodology/approachData were collected from a sample of teachers in Bahrain, using self-report measures. The data were analyzed using regression analyses.FindingsThe findings reveal a significant negative relationship between principals' abusive leadership and teachers' intrinsic and extrinsic motivations. The results also show that the duration of the relationship moderates the correlation between abusive leadership and teachers' extrinsic motivation, with teachers who have been in longer relationships with their principals showing greater resistance to the detrimental effects of abusive leadership on their extrinsic motivation. Group size was found to moderate this correlation, with larger groups exhibiting stronger buffering against the negative effect of abusive leadership.Originality/valueThe findings provide valuable insights into the dynamics of abusive leadership in educational settings and the potential moderating factors that can help alleviate its detrimental effects on teachers' motivations.

Authors: Kang Lin , Wang Jie , Chen Junjie , Yang Di 
Published: January 2024

PurposeSince the performance of vehicular users and cellular users (CUE) in Vehicular networks is highly affected by the allocated resources to them. The purpose of this paper is to investigate the resource allocation for vehicular communications when multiple V2V links and a V2I link share spectrum with CUE in uplink communication under different Quality of Service (QoS).Design/methodology/approachAn optimization model to maximize the V2I capacity is established based on slowly varying large-scale fading channel information. Multiple V2V links are clustered based on sparrow search algorithm (SSA) to reduce interference. Then, a weighted tripartite graph is constructed by jointly optimizing the power of CUE, V2I and V2V clusters. Finally, spectrum resources are allocated based on a weighted 3D matching algorithm.FindingsThe performance of the proposed algorithm is tested. Simulation results show that the proposed algorithm can maximize the channel capacity of V2I while ensuring the reliability of V2V and the quality of service of CUE.Originality/valueThere is a lack of research on resource allocation algorithms of CUE, V2I and multiple V2V in different QoS. To solve the problem, one new resource allocation algorithm is proposed in this paper. Firstly, multiple V2V links are clustered using SSA to reduce interference. Secondly, the power allocation of CUE, V2I and V2V is jointly optimized. Finally, the weighted 3D matching algorithm is used to allocate spectrum resources.
Real Estate Insights Individuals, beliefs and decision-making in commercial real estate markets: some reflections from the past
Authors: Lizieri Colin 
Published: January 2024

PurposeThe aim of this Real Estate Insight is to comment upon commercial real estate research. Much of the current research on commercial real estate sits in academic silos, constrained by disciplinary boundaries and rejecting insights from other areas. This can lead to an impoverished understanding of the processes and practices that drive market behaviour.Design/methodology/approachThis Real Estate Insight, through the lens of history, draws on insights from a century earlier and, in particular, from the work of Frank Ramsey; the paper argues that market behaviour is shaped by the role of key actors and persistent beliefs which need to be accounted for in our models of market practice.FindingsThe paper argues that current research paradigms need to accommodate agency explicitly into existing models and that real estate research will benefit immensely if researcher were more open in seeking ideas from outside the real estate field and to be more open to external ideas and concepts.Practical implicationsThe paper suggests that property research needs to be more embracing of other academic disciplines to develop a full understanding of the numerous and various drivers within commercial real estate markets.Originality/valueThis is a review of how beliefs impact upon commercial real estate markets. As with many things, history can help researchers today get a broader and more appropriate perspective on market drivers and how they affect decision-making.
A new gray optimization model for disposing or re-commercializing unsold goods in reverse logistics networks with a cross-docking center
Authors: Rajabzadeh Mohsen , Mousavi Seyed Meysam , Azimi Farzad 
Published: January 2024

PurposeThis paper investigates a problem in a reverse logistics (RLs) network to decide whether to dispose of unsold goods in primary stores or re-commercialize them in outlet centers. By deducting the costs associated with each policy from its revenue, this study aims to maximize the profit from managing unsold goods.Design/methodology/approachA new mixed-integer linear programming model has been developed to address the problem, which considers the selling prices of products in primary and secondary stores and the costs of transportation, cross-docking and returning unwanted items. As a result of uncertain nature of the cost and time parameters, gray numbers are used to deal with it. In addition, an innovative uncertain solution approach for gray programming problems is presented that considers objective function satisfaction level as an indicator of optimism.FindingsAccording to the results, higher costs, including transportation, cross-docking and return costs, make sending goods to outlet centers unprofitable and more goods are disposed of in primary stores. Prices in primary and secondary stores heavily influence the number of discarded goods. Higher prices in primary stores result in more disposed of goods, while higher prices in secondary stores result in fewer. As a result of the proposed method, the objective function satisfaction level can be viewed as a measure of optimism.Originality/valueAn integral contribution of this study is developing a new mixed-integer linear programming model for selecting the appropriate goods for re-commercialization and choosing the best outlet center based on the products' price and total profit. Another novelty of the proposed model is considering the matching percentage of boxes with secondary stores’ desired product lists and the probability of returning goods due to non-compliance with delivery dates. Moreover, a new uncertain solution approach is developed to solve mathematical programming problems with gray parameters.

INHABITING LIMINALITY: The Temporal, Spatial and Experiential Assemblage of Emancipatory Practices in the Lives of Housing Squatters in Rome, Italy
Authors: Cacciotti Chiara 
Published: January 2024

AbstractIn this article I question notions of urban liminality by foregrounding the temporal, spatial and experiential dimensions underpinning their formations. I focus on liminal practices of inhabitation in the context of a housing squat in Rome, Italy, by investigating how a permanent housing deprivation condition, once politically organized in a squatted building, can anchor processes of empowerment and political mobilization. To do so, I put forward a rereading of liminality, not necessarily as a temporary state but rather as a more comprehensive spatial–temporal assemblage, by offering a tripartite reading of liminal conditions in their spatial, temporal and experiential dimensions. My goal is to offer an analysis of urban and housing liminality that transcends totalizing narratives of exceptionality, temporariness or straightforward annihilation, advancing instead a more nuanced reading—where liminality can be seen either as a vehicle for social depotentiation or as the grounds for collective forms of emancipatory practices.

Published: January 2024

AbstractLatent fingerprints were successfully visualized using fluorescence lifetime imaging (FLIM) on paper which emits strong fluorescence with a lifetime close to that of fingerprints and thus from which it is difficult for time‐resolved spectroscopy to visualize fingerprints. Latent fingerprint samples on paper were excited using a 450 nm or 532 nm nanosecond pulsed‐laser, and time‐resolved fluorescence images were obtained at a delay time of 6–16 ns in intervals of 1 ns, to the excitation pulse. The excitation beam was expanded using a lens, and the fluorescence from the fingerprints was captured using an intensified CCD camera. Because of the large fluorescence intensity of the background paper of approximately two to four orders of magnitude larger than that of the fingerprint, the fingerprint was not visualized on each fluorescence image by time‐resolved spectroscopy. However, the fingerprint was visualized in a FLIM image constructed using a series of the fluorescence images for the case with the fluorescence intensity of the background paper being four orders of magnitude larger than that of the fingerprint. The difference in fluorescence lifetime in the FLIM image of the visualized fingerprint and background paper was in the order of 0.1 ns, which was an order of magnitude smaller than the inherent fluorescence lifetime of a few nanoseconds for the fingerprints and paper. It was demonstrated that, at a background fluorescence intensity with a certain order of magnitude larger than that of fingerprints, FLIM has the potential to visualize latent fingerprints which cannot be visualized by time‐resolved spectroscopy.
The unknown unknown: A framework for assessing environmental DNA assay specificity against unsampled taxa
Authors: Wilcox Taylor M. , Kronenberger John A. , Young Michael K. , Mason Daniel H. , Franklin Thomas W. , Schwartz Michael K. 
Published: January 2024

AbstractTaxon‐specific quantitative PCR (qPCR) assays are commonly used for environmental DNA sampling‐based inference of animal presence. These assays require thorough validation to ensure that amplification truly indicates detection of the target taxon, but a thorough validation is difficult when there are potentially many non‐target taxa, some of which may have incomplete taxonomies. Here, we use a previously published, quantitative model of cross‐amplification risk to describe a framework for assessing qPCR assay specificity when there is missing information and it is not possible to assess assay specificity for each individual non‐target confamilial. In this framework, we predict assay specificity against unsampled taxa (non‐target taxa without sequence data available) using the sequence information that is available for other confamilials. We demonstrate this framework using four case study assays for: (1) An endemic, freshwater arthropod (meltwater stonefly; Lednia tumana), (2) a globally distributed, marine ascidian (Didemnum perlucidum), (3) a continentally distributed freshwater crustacean (virile crayfish; Faxonius virilis, deanae and nais species complex) and (4) a globally distributed freshwater teleost (common carp; Cyprinus carpio and its close relative C. rubrofuscus). We tested the robustness of our approach to missing information by simulating application of our framework for all possible subsamples of 20—all non‐target taxa. Our results suggest that the modelling framework results in estimates which are largely concordant with observed levels of cross‐amplification risk using all available sequence data, even when there are high levels of data missingness. We explore potential limitations and extensions of this approach for assessing assay specificity and provide users with an R Markdown template for generating reproducible reports to support their own assay validation efforts.

AbstractObjectivesTo evaluate the efficacy and safety of adalimumab (ADA) combined with Tripterygium wilfordii Hook F (TwHF) in the treatment of methotrexate (MTX)‐inadequate response patients with rheumatoid arthritis (RA).MethodsIn this multicenter, open‐label, randomized controlled clinical trial, 64 RA patients with inadequate response to MTX were 1:1 randomly assigned into treatment or control groups. The treatment group was treated with ADA in combination with TwHF, and the control group was treated with ADA in combination with MTX for 24 weeks. The primary endpoint was the percentage of patients having low disease activity (2.6 ≤ DAS28‐ESR < 3.2) and remission rates (DAS28‐ESR < 2.6) at week 24.ResultsIn total, 53 of the 64 patients (82.8%) completed this 24‐week clinical trial. By intent‐to‐treat (ITT) analysis, a comparable outcome was observed between the two groups. The percentage of patients achieving low disease activity in the treatment group and control group were 43.8% and 46.9% (95% CI, 21.28 to 27.48, p = .802). Percentage of patients achieving low disease activity rates were respectively 28.1% and 31.3% in the treatment group and control group (95% CI, 19.18 to 25.58, p = .784). In per‐protocol (PP) analysis, the results were consistent with the ITT model. The incidence of adverse events was comparable between the two groups.ConclusionsThere were no significant differences in efficacy and safety between ADA combined with TwHF versus ADA combined with MTX in the treatment of RA. TwHF might be an alternative treatment for RA patients who are intolerant to MTX.
STA‐21 regulates Th‐17/Treg balance and synovial fibroblasts functions in rheumatoid arthritis

Published: January 2024

AbstractJAK/STAT signaling pathway plays a significant role in cytokines and growth factors signaling involved in the pathogenesis of rheumatoid arthritis (RA). STAT3 is a major downstream signaling mediator of important pro‐inflammatory cytokines involved in Th‐17 cell differentiation playing a significant role in regulating Th‐17/ Treg balance and the development of autoimmune diseases, especially RA. Studies also have reported the role of the STAT3 pathway in inflammatory and destructive functions of synovial fibroblasts (SFs) in RA. STA‐21 is a small molecule inhibitor that can inhibit STAT3 activation impairing the expression of STAT3 target genes. In this study, we tested whether a STAT3 inhibitor, STA‐21, can alter Th‐17/Treg balance and SF functions in RA. Peripheral blood mononuclear cells (PBMC) and SFs were isolated from 34 RA patients undergoing orthopedic surgery and 15 healthy controls to investigate in vitro effects of STA‐21. The main assays were MTT assay, PI staining, reverse transcription‐PCR (RT‐PCR), flow cytometric analysis, and ELISA. Results showed that STA‐21 reduced the proportion of Th‐17 cells and the expression of STAT3 target genes, RORγt, IL‐21, and IL‐23R involved in Th‐17 cells differentiation while it conversely increased the proportion of Treg cells, which theoretically may result in suppression of inflammation. We found that STAT3 activation and its target gene expression increased in RA‐SFs. In addition, results showed that STA‐21 can reduce the expression of STAT3 target genes related to cell proliferation, apoptosis, and inflammation leading to a decrease in proliferation and conversely increase in apoptosis of RA‐SFs. Overall, our findings provide evidence that STA‐21 can reduce inflammatory immune processes conducted by T cells and RA‐SFs in RA, suggesting that this compound is a suitable option for clinical studies in RA.
