Network capacity improvement in 5G by using dynamic fractional frequency reuse (FFR)
Authors: Alotaibi Sultan 
Published: April 2023

AbstractThe FFR approach reduces interference between macrocells and small cells/femtocells, which are installed within macrocell’s range. Dense deployment and unplanned installation of small cells and femtocells has a detrimental impact on the performance of the system as a result of the interference. Thus, the FFR concept distributes resources to maintain interference. However, some small cells/femtocells may suffer from shortage resources. In this work, dynamic FFR mechanism has been proposed. The scheme maximizes small cell/femtocell network’s capacity. The strategy aims to boost small cell/femotcell network’s capacity and system throughput. The fundamental goal of this research is to maximize the dedicated radio resources, which are allocated to small cells/femtocells, based on a predetermined cost function. According to the cost function, which is computed for all sub-regions, the proposed dynamic FFR will allocate more radio resources to small cells/femtocells, which suffer from lack resources. The highest degree of the cost function of a certain sub-region would have the largest amount of small cells/femtocells. The sub-region with the lowest cost function would receive fewer radio resources for small cell/femtocell UEs. The throughput is utilized as a metric for the purpose of evaluating the proposed strategy. MATLAB simulation is conducted for that reason. The results show that the proposed technique outperforms the fixed FFR.

Abstract
A child’s early literacy and language skills are the most reliable predictor of future academic achievement. Despite vast amounts of research supporting this link, many children start formal schooling with low early literacy skills. Without intervention or support, these children will likely continue to fall behind their peers. This exploratory study investigated the effectiveness of a parent-led phonological awareness programme (n = 3), implemented at home with their 4-year-old children (n = 4) in Christchurch, New Zealand. This study used an exploratory case study mixed methods design. The programme focused on improving children’s phonological awareness skills by providing parents with readily available activities which taught a range of phonological skills. Parents were supported throughout implementation by the researcher with coaching and modelling. Overall, the study found parents to be effective at implementing the phonological awareness programme and facilitating the development of their children’s emergent literacy skills. Children demonstrated increased phoneme identification, blending and segmenting skills and additional skills not explicitly taught, such as phoneme manipulation. Participation in the programme also positively affected children’s interest in literacy activities, such as reading and writing. Parent reports identified positive effects on children’s articulation, speech, engagement and overall confidence. Parents were positively affected by their participation in the programme, with reports of increased confidence in their English proficiencies and literacy skill development.
Neutrosophic Log-Logistic Distribution Model in Complex Alloy Metal Melting Point Applications
Authors: Rao Gadde Srinivasa 
Published: April 2023

AbstractThe log-logistic distribution is more comprehensively applied in the area of survival and reliability engineering analysis for modeling the lifetime data practices of both human and electronic designs. The goal of this paper is to develop a generalization of the classical pattern log-logistic distribution, known as the neutrosophic log-logistic distribution (NLLD), to model various survival and reliability engineering data with indeterminacies. The developed distribution is especially useful for modeling indeterminate data that is roughly positively skewed. This paper discusses the developed NLLD’s main statistical properties such as neutrosophic survival function, neutrosophic hazard rate, neutrosophic moments, and neutrosophic mean time failure. Furthermore, the neutrosophic parameters are estimated using the well-known maximum likelihood (ML) estimation method in a neutrosophic environment. A simulation study is carried out to establish the achievement of the estimated neutrosophic parameters. As a final point, the proposed NLLD applications in the real world have been discussed with the help of real data. The real data illustrated that the efficiency of the proposed model as compared with the existing models.
Two Dimensions of Responsibility: Quality and Competence of Will
Authors: MADIGAN TAYLOR 
Published: April 2023

AbstractPure quality of will theories claim that ‘the ultimate object’ of our responsibility responses (i.e., praise and blame) is the quality of our will. Any such theory is false—or so I argue. There is a second dimension of (moral) responsibility, independent of quality of will, that our responsibility responses track and take as their object—namely, how adroitly we are able to translate our will into action; I call this competence of will. I offer a conjectural explanation of the two dimensions of (moral) responsibility: it matters to us that people actually perform adequately well because of how much it matters to us that we are able to live and work together successfully.
The Generalized Risk-Adjusted Cost-Effectiveness (GRACE) Model for Measuring the Value of Gains in Health: An Exact Formulation
Authors: Lakdawalla Darius N. , Phelps Charles E. 
Published: April 2023

AbstractThe generalized risk-adjusted cost-effectiveness (GRACE) analysis method modifies standard cost-effectiveness analysis (CEA), the primary method currently used worldwide to value health improvements arising from healthcare interventions. Generalizing standard CEA, GRACE allows for decreasing or even increasing returns to health. Previous presentations of GRACE have relied extensively on Taylor Series expansion methods to specify key model parameters, including those that properly adjust for illness severity and preexisting disability, consequences of uncertain treatment outcomes, and the marginal rate of substitution between life expectancy and health-related quality of life. Standard CEA cannot account for these sources of value or cost in its valuation of medical treatments. However, calculations of GRACE measures based on Taylor Series are approximations, which may be poorly behaved in some contexts. This paper provides a new approach for implementing GRACE, using exact utility functions instead of Taylor Series approximations. While any proper utility function will suffice, we illustrate with three well-known functions: constant relative risk aversion (CRRA) utility; hyperbolic absolute risk aversion (HARA) utility, of which CRRA is a special case; and expo-power (EP) utility, of which constant absolute risk aversion (CARA) is a special case. The analysis then extends from two-period to multiperiod models. We discuss methods to estimate parameters of HARA and EP functions using two different types of data, one from discrete choice experiments and the other from “happiness economics” methods. We conclude with some reflections on how this analysis might affect benefit-cost analysis studies of healthcare interventions.
The boundedness of the bilinear oscillatory integral along a parabola
Authors: Li Guoliang , Li Junfeng 
Published: April 2023

AbstractIn this paper, the $L^p(\mathbb{R})\times L^q(\mathbb{R})\rightarrow L^r(\mathbb{R})$ boundedness of the bilinear oscillatory integral along parabola
\begin{equation*}
T_\beta(f, g)(x)=p.v.\int_{{\mathbb R}} f(x-t)g(x-t^{2})\,{\rm e}^{i |t|^{\beta}}\,\frac{{\rm d}t}{t}
\end{equation*}is set up, where β > 1 or β < 0, $\frac{1}{p}+\frac{1}{q}=\frac{1}{r}$ and $\frac{1}{2}\lt r\lt\infty$, p > 1 and q > 1. The result for the case β < 0 extends the $L^\infty\times L^2\to L^2$ boundedness obtained by Fan and Li (D. Fan and X. Li, A bilinear oscillatory integral along parabolas, Positivity 13(2) (2009), 339–366) by confirming an open question raised in it.
The rational homotopy type of homotopy fibrations over connected sums
Authors: Chenery Sebastian 
Published: April 2023

AbstractWe provide a simple condition on rational cohomology for the total space of a pullback fibration over a connected sum to have the rational homotopy type of a connected sum after looping. This takes inspiration from a recent work of Jeffrey and Selick, in which they study pullback fibrations of this type but under stronger hypotheses compared to our result.

AbstractFossils are more and more used in phylogenetic evolutionary studies either for clade calibration, or as terminals in a dataset including morphological characters. The strength of these methodological advances relies however on the quality and completeness of the fossil record. For crickets (Insecta, Orthoptera, Gryllidea), few ancient (pre-Cenozoic) well-preserved fossils are known, except for isolated wings often classified in purely fossil groups and a few fossils found in Cretaceous amber. Here, we present two remarkable fossils from mid-Cretaceous amber of France, that were imaged using X-ray synchrotron microtomography and exhibit an exquisite preservation allowing description with a precision similar to that of extant taxa.Palaeonemobius occidentalisLaurent and Desutter-Grandcolas,gen. nov., sp. nov.andPicogryllus carentonensisJosse and Desutter-Grandcolas,gen. nov., sp. nov.are the oldest representatives of the Nemobiinae and Podoscirtinae subfamilies of the Trigonidiidae and Oecanthidae families respectively.P. carentonensisJosse and Desutter-Grandcolas,gen. nov., sp. nov.is also the smallest adult male with a full stridulatory apparatus ever documented in crickets (body length 3.3 mm), and the first taxon of the cricket clade for which male genitalia can be partly described. We discuss the significance of Cretaceous fossils of crickets for future evolutionary studies of this clade.
Geochemistry and Sr–Nd isotopic characteristics of ferroan-magnesian metaluminous granites of the NW Sanandaj–Sirjan zone, Iran: granite formation in a compressional–extensional setting during Late Jurassic time

Published: April 2023

AbstractThe Almogholagh–Dehgolan region is in the North Sanandaj–Sirjan zone of NW Iran. The granites of the region are metaluminous and display geochemical and textural characteristics of transitional granites between ferroan (A-type) and I-type granites. In geotectonic discrimination diagrams, the Almogholagh–Dehgolan granites plot mainly in the fields of within-plate granites and volcanic arc granites. With the exception of the Qalaylan granites, parts of other granites resemble A2-type granites. Granites of the Qalaylan intrusive body have petrographic and geochemical features close to I-type granites and are not A-type. Primary mantle and chondrite-normalized spider diagrams show enrichments in light rare earth elements relative to heavy rare earth elements. For an age of 150 Ma, the initial87Sr/86Sr and143Nd/144Nd ratios vary from 0.702769 to 0.706545 and from 0.512431 to 0.512558, respectively. Epsilon Nd values vary in a relatively limited range between −0.3 and +2.2, which corresponds to a mixed mantle–crustal source. On the basis of new geochemical and isotopic data, we suggest a geodynamic model involving partial melting of lower crustal rocks with the contribution of mantle magmas in a weakly extensional tectonic setting for the generation of the A-type granites of the region. The occurrence of ferroan (A-type) granites in this region of the Sanandaj–Sirjan zone indicates the existence of a partly extensional tectonic environment in a mainly compressional subduction-related regime in Late Jurassic time.

$C^{*}$
-algebra generated by a semigroup of isometries
$\{v_{(m,n)}\,:\, m,n \in \mathbb{N}\}$
whose range projections commute. We analyse the structure of KMS states on

for the time evolution determined by a homomorphism
$c\,:\,\mathbb{Z}^{2} \to \mathbb{R}$
. In contrast to the reduced version

, we show that the set of KMS states on
$C_{c}^{*}(\mathbb{N}^{2})$
has a rich structure. In particular, we exhibit uncountably many extremal KMS states of type I, II and III.
Law, Labour and Lunch in France at the Turn of the Twentieth Century
Authors: Bruegel Martin 
Published: April 2023

AbstractVentilation emerged as an efficient technique to reduce the health impact of dust and gas in workspaces around 1900. However, this technical solution to a major sanitary problem collided with the human factor. When, in 1894, French law imposed shop-floor clearance during lunch to facilitate aeration, workers resisted the injunction as a disturbance of their daily eating routine. Authorities relied on labour inspectors to find solutions to contentious situations. The 1901 union-led strike in the high-fashion district in Paris propelled the issue to national attention. Striking women demanded the strict enforcement of the aeration rule. The executive obliged, but the newfound zeal subsequently rekindled antagonism towards the regulation. Reversing their claim, women workers launched a community-based petitioning campaign to return to pre-strike tolerance. Rumours of another walk-out by seamstresses, triggered by the enforcement of the regulation in 1902, precipitated a governmental volte-face. Authorities apprehended the power of the street and the threat of public disorder. Government yielded to the women's influence. A more relaxed version of the decree – it did not automatically require the evacuation of workspaces – appeared on 29 November 1904. It had taken ten years, and a zigzagging trajectory, to overcome the unanticipated consequences of purposive legislative action. The new rules proved to be very solid: they remained in place until Covid-19 pushed the government to temporarily authorize eating at one's workplace to prevent the spread of the virus in canteens and restaurants.
‘REACHING OUT’ OR INSTITUTIONAL VIRTUE-SIGNALLING? THE ROLE OF COMMUNITY OPERA PROJECTS IN UK OPERA HOUSES TODAY
Authors: Rudland Oliver 
Published: April 2023

AbstractThe education and outreach departments that coordinate community and participation projects have become a ubiquitous component of opera houses in the UK over the last 40 years yet rarely do their productions appear on the main stage. This article considers recent projects run by Opera North, English National Opera, Opera Holland Park and Glyndebourne and asks whether opera houses are genuinely committed to connecting communities with opera or treat outreach as no more than a means of obtaining funding. The article explores the history of the development of outreach departments and the potential that community involvement offers as a revitalising force for the operatic artform. A series of interviews with opera professionals brings the debate up to date.
Spanish heritage language learners’ motivational profile in the postsecondary classroom: Insights from psychological network modeling

Published: April 2023

AbstractThis study sought to investigate the psychological network structure of adult Spanish heritage language (HL) learners’ motivational profile by considering interconnections among the following variables: the possible HL selves, family influence, intended HL learning effort, HL achievement goal orientations, HL enjoyment, HL anxiety, perceived classroom environment, and critical language awareness. In line with a complex systems perspective, mutually interdependent connections among variables were estimated using psychological network modeling. The analysis revealed a majority of positive associations among the system constituents, with nodes representing the possible HL selves, HL enjoyment, and intended HL learning effort holding the most central influence on the network. Results also shed light on the unexplored relevance of critical language awareness in understanding HL learners’ motivational and emotional dispositions. We discuss the theoretical, pedagogical, and methodological implications of the study, highlighting the potential of network analysis for providing insights into complex psychological phenomena.

Abstract
Healthcare workers’ (HCWs) safety and availability to care for patients are critical during a pandemic such as the one caused by severe acute respiratory syndrome coronavirus 2. Among providers of different specialities, it is critical to protect those working in hospital settings with a high risk of infection. Using an agent-based simulation model, various staffing policies were developed and simulated for 90 days using data from the largest health systems in South Carolina. The model considers staffing policies that include geographic segregation, interpersonal contact limits, and a combination of factors, including the patient census, transmission rates, vaccination status of providers, hospital capacity, incubation time, quarantine period, and interactions between patients and providers. Comparing the existing practices to various risk-adjusted staffing policies, model predictions show that restricted teaming and rotating schedules significantly (p-value <0.01) reduced weekly HCW unavailability and the number of infected HCWs by 22% and 38%, respectively, when the vaccination rates among HCWs were lower (<75%). However, as the vaccination rate increases, the benefits of risk-adjusted policies diminish; and when 90% of HCWs were vaccinated, there were no significant (p-value = 0.09) benefits. Although these simulated outcomes are specific to one health system, our findings can be generalised to other health systems with multiple locations.
Shared State Responsibility for Land-Based Marine Plastic Pollution
Authors: Tanaka Yoshifumi 
Published: April 2023

AbstractPlastic litter is introduced into the oceans from land-based sources located in many countries around the world. Marine plastic pollution may therefore be attributable to multiple states, resulting in shared state responsibility. This article discusses the issue of shared state responsibility for land-based marine plastic pollution by examining (i) primary rules of international law concerning the prevention of land-based marine plastic pollution; (ii) secondary rules of international law on this subject; and (iii) possible ways of strengthening the primary rules. It concludes that the barrier for the invocation of state responsibility may become higher in cases of shared state responsibility. Three cumulative solutions to this problem are proposed: elaborating the obligation of due diligence, strengthening compliance procedures, and interlinking regimes governing the marine environment and international watercourses.
Interaction of Air Pressure and Groundwater as Main Cause of Sub‐Daily Relative Seismic Velocity Changes
Authors: Kramer R. , Lu Y. , Bokelmann G. 
Published: April 2023

AbstractOur study investigates variations of seismic velocity that occur over short time scales of hours. We use coda wave interferometry to inspect 5 months of continuous data from a seismological array in southern Germany. This results in relative seismic velocities (dv/v) that show temporal variations on the order of 10−4. Spectra of the velocity time series contain strong daily and sub‐daily behavior indicating that the daily and sub‐daily changes in the seismic velocity are primarily caused by atmospheric tides. We also note the influence of temperature changes on daily variations, but as a second‐order effect. The explanatory model focuses on depth variations of the groundwater table, linking atmospheric pressure (loading and de‐loading the Earth's surface) to variations in seismic velocity. Our results highlight an important environmental influence on seismic velocity that needs to be considered before seismic velocity variations can be used for inspecting fluid and stress variations in situ.
Regime Shift of the Sea Level Trend in the South China Sea Modulated by the Tropical Pacific Decadal Variability

Published: April 2023

AbstractDuring the altimeter era, the sea level in the South China Sea (SCS) and western tropical Pacific (WTP) experienced significant decadal variability. The sea level rose during 1993–2009 and fell during 2010–2019. The decadal variability of Walker Circulation associated with the Pacific Decadal Oscillation can explain the sea level variability in the WTP to a great extent. The wind forced westward propagating Rossby waves increased (decreased) the sea level in the WTP during 1993–2009 (2010–2019). However, the interior wind forcing has a negligible contribution to the decadal variability of the sea level in the SCS. The remote forcing from WTP through the oceanic bridge was supposed to play a dominant role. The sensitive experiments of a 1½‐layer model and Regional Oceanic Modeling System suggested that the sea level signals via the Sibutu Passage and Mindoro Strait accounted for the decadal variability of sea level in the central basin of SCS.
On Consistent Parameterizations for Both Dominant Wind‐Waves and Spectral Tail Directionality
Authors: Alday Matias , Ardhuin Fabrice 
Published: April 2023

AbstractNumerical wave models have been developed to reproduce the evolution of waves generated in all directions and over a wide range of wavelengths. The amount of wave energy in the different directions and wavelength is the result of a number of physical processes that are not well understood and that may not be represented in parameterizations. Models have generally been tuned to reproduce dominant wave properties: significant wave height, mean direction, dominant wavelengths. A recent update in wave dissipation parameterizations has shown that it can produce realistic energy levels and directional distribution for shorter waves too. Here, we show that this new formulation of the wave energy sink can reproduce the variability of measured infrasound power below a frequency of 2 Hz, associated with a large energy level of waves propagating perpendicular to the wind, for waves with frequencies up to 1 Hz. The details are sensitive to the balance between the non‐linear transfer of energy away from the wind direction, and the influence of dominant and relatively long waves on the dissipation of shorter waves in other directions.
