Authors: Kobayashi Kan , Tomioka Sadatake , Takahashi Masahiro , Kodera Masatoshi 
Published: February 2023

AbstractCHEMKIN-Pro was used to build a custom-made reduced reaction mechanism for a 3D simulation of C2H4/Air reaction in a supersonic combustion ramjet (scramjet) combustor for the JAXA S-520-RD1 flight test performed on 24 July 2022. It was also attempted to reproduce the effect of unavoidable H2O vitiation in the facility (ground) test on combustion characteristics. USC Mech II (a 111-species mechanism) was applied as the master mechanism. First, 1D simulation was conducted by applying a plug flow reactor model; 34-, 23-, 20-, 18-, and 19-species mechanisms were suggested as candidates for reduced mechanism. Then, 0D ignition delay simulation by applying a perfectly stirred reactor model by CHEMKIN-Pro, 2D reacting flow simulation by CRUNCH CFD, and 3D reacting flow simulation by RANS were performed to select the most suitable reduced mechanism. The 20-species (96-elementary-reactions) mechanism consisted of H2, O2, N2, H2O, CO2, CO, H, O, OH, HO2, CH2, CH2*, CH3, HCO, CH2O, CH3O, C2H2, C2H3, C2H4, and CH2CHO and was selected as the best-reduced reaction mechanism for C2H4-fueled 3D simulation under the flight and facility conditions corresponding to the RD1 flight test.
Static analysis of prestressed micropile-raft foundation with varying lengths resting on sandy soil
Authors: Ebadi-Jamkhaneh Mehdi , Kontoni Denise-Penelope N. 
Published: February 2023

AbstractThe micropile-raft system is used in the foundation system of buildings due to the combination of the advantages of raft foundations and micropiles. In this paper, the numerical model was calibrated and validated with a field test, and then several parametric studies were performed. The overarching aim of the study is to determine the efficiency of different arrangements of micropiles and the effects of these parameters on the behavior of piled raft foundations in sandy soil. Parameters including diameter, length, and distance of micropiles from each other were considered in the analyses. Prestressed rebars have been used to increase the load-bearing capacity and prevent premature buckling under severe compressive load. Therefore, to compensate for the weak bearing capacity of the raft foundation, a micropile system equipped with prestressed rebars was considered to increase the bearing capacity of the foundation. The results revealed that using a set of micropiles with a diameter of 30 cm and a length of 10 m had the maximum efficiency among other models. Furthermore, an innovative arrangement of micropiles was proposed in which a set of micropiles with a length of 30 m was placed at the middle region of the foundation, and in the peripheral area of the foundation, several short micropiles were used.

AbstractWe address the practical issue that popular computation platforms like Matlab$$^{\copyright }$$

are unable to perform the Jordan normal (canonical) form J and the associated transform matrix P on a high-dimension matrix. Given the knowledge of the eigenvalues and eigenvectors of n-square matrix A obtained on these platforms, we present an efficient algorithm of Jordan transform with detailed computation steps. The efficiency is demonstrated by comparing the simulation results of 11 examples with varying orders of n to that computed by the symbolic-based and capacity-limited routine $$[P, J] = {\textsf {jordan}}(A)$$

Surface Artifact Scatters, Data Collection, and Significance
Authors: Douglass Matthew J. , Wandsnider LuAnn , Holdaway Simon J. 
Published: February 2023

ABSTRACTThe three authors research surface archaeological records dominated by low-density scatters and isolated artifacts, archaeological phenomena frequently encountered during cultural resource management (CRM) projects in areas of the United States and Australia. We each began researching surface artifact scatters for different reasons but converged on approaches that emphasize the formation of these forms of archaeological deposits. Through a variety of projects, we asked a common set of questions about the processes that both buried and exposed these materials, the methods needed to obtain a chronology in different regions, and the ways we might interpret artifacts found together in different densities. Answering these questions led to the collection and analyses of datasets in innovative ways and the questioning of a number of archaeological categories often thought of as fundamental for archaeological research. Here, we review examples of our respective research and consider the implications for CRM projects dealing with surface lithics.
The National Cultural Resources Information Management System (NCRIMS)
Authors: Halford F. Kirk , Ables Dayna M. 
Published: February 2023

ABSTRACTDespite making great strides over the past 50 years, cultural resources data management and synthesis continues to be elusive and nonstandardized, with each state and agency developing disparate systems that do not easily mesh. The Bureau of Land Management (BLM) has embarked on a national initiative by creating a National Cultural Resources Data Standard (NCRDS) that works to address many long-standing data organization issues. The NCRDS allows for the application of more rigorous data management principles that facilitate landscape-level planning and data modeling on BLM-administered lands across the western United States. The NCRDS and associated National Cultural Resources Information Management System (NCRIMS) contains normalized data from 11 western State Historic Preservation Offices (SHPOs) and BLM data stores. NCRIMS is a web-based application hosted by the BLM's National Operations Center (NOC) Enterprise Geographic Information System (EGIS). NCRIMS allows for high-level planning during local, regional, and multistate project analyses and undertakings, facilitating consideration of cultural heritage values early in the planning process versus late stages as has been traditional. This allows the BLM to more proactively, effectively, and efficiently answer data calls and inform agency decision-makers on possible impacts to cultural heritage resources by proposed or ongoing agency actions.
Will It Ever Be FAIR?
Authors: Nicholson Christopher , Kansa Sarah , Gupta Neha , Fernandez Rachel 
Published: February 2023

AbstractA fundamental task of archaeology is to address challenging scientific questions related to the complexity of human societies. If we are to systematically understand the processes that affect human societies on multiple spatial and temporal scales, research leveraging existing archaeological data is essential. However, only a fraction of the data from archaeological projects are publicly findable or accessible, let alone interoperable or reusable. This is the case despite statements of disciplinary ethics, availability of capable technologies for data stewardship, publications providing guidance, and legal mandates. This article introduces the FAIR principles for data stewardship in North American archaeology, which state that data should be Findable, Accessible, Interoperable, and Reusable. We call for efforts to promote widespread adoption of the FAIR and CARE (Collective benefit, Authority to control, Responsibility, and Ethics) principles among professional organizations, publishers, data repositories, and researchers. We also call for adoption and implementation of requirements to adhere to these principles by governmental agencies, funding bodies, and other regulators of archaeological research. Ultimately, adoption of the FAIR principles in an ethical framework contributes to our understanding of our human experience and can lead to greater integration and reuse of research results, fostering increased partnerships between academia and industry.
Derivational networks of onomatopoeias in English and Slovak
Authors: Körtvélyessy Lívia , Andrej Ľubomír 
Published: February 2023

AbstractThis article presents research into derivational properties of onomatopoeias in English and in Slovak. Onomatopoeias are defined narrowly in our approach, being restricted to the direct imitation of sounds of extra-linguistic reality. Our sample of 40 onomatopoeic words consists of two sound types: the sounds of animals and the sounds resulting from various falls, strokes, and bursts. A derivational network was produced for each such word. The evaluation parameters comprise derivational capacity, maximum derivational network, saturation value, number of derivation orders, most productive semantic categories by order of derivation, typical combinations of semantic categories, and derivational processes. An evaluation of the networks enabled us to answer the question of whether onomatopoeias are productive word-formation bases, to compare the two Sound Types, and to compare onomatopoeia-based networks to those based on non-iconic vocabulary. These results contribute to a better understanding of the word-formation systems in the compared languages and of the status of onomatopoeias with regard to non-iconic vocabulary.
Joining forces: the value of design partnering with operational research to improve healthcare delivery
Authors: Lamé Guillaume , Crowe Sonya , Komashie Alexander , Royston Geoff 
Published: February 2023

AbstractA wide range of disciplines are directing their methods and tools to help address the challenges of healthcare. Chief among these are design and operational research (OR). Though they have much in common, these two disciplines have existed in isolation for most of their history and there is currently a gulf between the two research communities. In this position paper, we rapidly review the contributions of design and OR in healthcare. We then identify similarities and complementarities between the two disciplines and communities when they consider healthcare systems. Finally, we propose practical steps to enable better collaboration. Our focus is on finding ways in which the two disciplines complement each other. When applying design to healthcare services, designers may wish to learn from OR, which has a long history of supporting improvements in healthcare organisation and services, particularly using quantitative data and analysis and modelling methods. In return, design has distinctive qualities that could augment the OR approach, such as its emphasis on wide and creative search for potential solutions, and iterative co-production and prototyping of solutions with clients. Better collaboration will require a coordinated effort but could yield a more comprehensive and effective approach to improving healthcare systems.

AbstractErdős proved that every real number is the sum of two Liouville numbers. A setWof complex numbers is said to have the Erdős property if every real number is the sum of two members ofW. Mahler divided the set of all transcendental numbers into three disjoint classesS,TandUsuch that, in particular, any two complex numbers which are algebraically dependent lie in the same class. The set of Liouville numbers is a proper subset of the setUand has Lebesgue measure zero. It is proved here, using a theorem of Weil on locally compact groups, that if$m\in [0,\infty )$, then there exist$2^{\mathfrak {c}}$dense subsetsWofSeach of Lebesgue measuremsuch thatWhas the Erdős property and no two of theseWare homeomorphic. It is also proved that there are$2^{\mathfrak {c}}$dense subsetsWofSeach of full Lebesgue measure, which have the Erdős property. Finally, it is proved that there are$2^{\mathfrak {c}}$dense subsetsWofSsuch that every complex number is the sum of two members ofWand such that no two of theseWare homeomorphic.
From museumization to decolonization: fostering critical dialogues in the history of science with a Haida eagle mask
Authors: Sera-Shriar Efram 
Published: February 2023

AbstractThis paper explores the process from museumization to decolonization through an examination of a Haida eagle mask currently on display in the Exploring Medicine gallery at the Science Museum in London. While elements of this discussion are well developed in some disciplines, such as Indigenous studies, anthropology and museum and heritage studies, this paper approaches the topic through the history of science, where decolonization and global perspectives are still gaining momentum. The aim therefore is to offer some opening perspectives and methods on how historians of science can use the ideas and approaches relating to decolonization in other fields, and apply them constructively to the history of science, particularly in museum settings. Decolonization is a complicated process and the focus of this paper is squarely on the preliminary steps of its implementation. To understand this process fully, the paper will recontextualize the Indigenous history of the Haida eagle mask at the Science Museum through a careful reconstruction of its provenance record. Through this process it will expose the politics of erasure and hidden voices in museum collections.

AbstractThis systematic review and meta-analysis aimed to investigate the effects of beetroot (BR) or nitrate supplements on body composition indices. A systematic search was conducted for randomised controlled trials (RCT) published up to August 2022 among online databases including Scopus, PubMed/Medline, Web of Science and Embase. Meta-analyses were carried out using a random-effects model. The I2 index was used to assess the heterogeneity of RCT. A total of twelve RCT met the inclusion criteria for this meta-analysis. The pooled effect size of included studies indicated that BR or nitrate supplementation did not change body weight (weighted mean differences (WMD): –0·14 kg, 95 % CI –1·22, 1·51; P = 0·836; I2 = 0 %), BMI (WMD: −0·07 kg/m2, 95 % CI −0·19,0·03; P = 0·174, I2 = 0 %), fat mass (WMD: –0·26 kg, 95 % CI –1·51, 0·98; P = 0·677, I2 = 0 %), waist circumference (WMD: –0·28 cm, 95 % CI –2·30, 1·74; P = 0·786, I2 = 0 %), body fat percentage (WMD: 0·18 %, 95 % CI –0·62, 0·99; P = 0·651, I2 = 0 %), fat-free mass (WMD: 0·31 kg, 95 % CI –0·31, 1·94; P = 0·703, I2 = 0 %) and waist-to-hip ratio (WMD: 0, 95 % CI –0·01, 0·02; P = 0·676, I2 = 0 %). Subgroup analyses based on trial duration, BR or nitrate dose, study design, baseline BMI and athletic status (athlete v. non-athlete) demonstrated similar results. Certainty of evidence across outcomes ranged from low to moderate. This meta-analysis study suggests that BR or nitrate supplements cannot efficiently ameliorate body composition indices regardless of supplement dosage, trial duration and athletic status.
The 1886 Southwest Railroad Strike, J. West Goodwin's Law and Order League, and the Blacklisting of Martin Irons
Authors: Pearson Chad 
Published: February 2023

AbstractThis article explores blacklisting practices following the massive 1886 Southwest strike staged by the Knights of Labor (KOL) against Jay Gould's railroad empire. It focuses mostly on strike leader Martin Irons and blacklisting advocate and newspaperman J. West Goodwin. The strike, which started in Sedalia, Missouri, before spreading to other states, was a disaster for the KOL. The union declined in its aftermath chiefly because of the repression unleashed by public and private forces, including businessmen-led Law and Order Leagues. After the strike, employers blacklisted many, including strike leader and Sedalia resident Martin Irons. Irons, constantly on the move, suffered from joblessness, underemployment, arrests, and broken health before he died in central Texas in 1900. Few blacklisting advocates wanted Irons to suffer more than J. West Goodwin. The Law and Order League leader and newspaperman repeatedly wrote about what he considered Martin Irons's moral lapses and shortsightedness. By focusing on Goodwin's promotion of blacklisting and Irons's post-strike struggles, this essay helps us better appreciate the underexplored dimensions of this form of punishment.
The prison-handicraft complex: Convict labour in colonial India
Authors: Yang Anand A. 
Published: February 2023

AbstractPrison labour was an integral part of the penal order in colonial India in the nineteenth and early twentieth centuries. Especially in Bengal, such coerced labour, overwhelmingly male, was increasingly deployed in handicrafts production rather than in extramural construction projects, a regimen that led to the development of a prison-handicraft complex. Colonial efforts to refine this system focused largely on increasing the severity of the conditions of incarceration and indoor work, but also on the conflicting goal of maximizing the profits of its handiwork. Prisons thus emerged as effective sites of handicrafts production, with the products of their forced labour facilitating the revival of the crafts industry whose growth is generally attributed to the rise of an international arts and crafts movement in Britain and India.

Published: February 2023

AbstractCystic echinococcosis (CE) is endemic in humans and domestic animals in eastern Africa. All the species of the Echinococcus granulosus sensu lato complex have been reported in this region except for E. equinus, possibly due to the small number of studies involving equids. This study reports the frequency of different Echinococcus species in donkeys from eastern Africa. A total of 5961 donkeys were examined during meat inspection in 3 slaughterhouses in Kenya. Identification of Echinococcus spp. was achieved through polymerase chain reaction-restriction fragment-length polymorphism and sequencing of the mitochondrial nicotinamide adenine dinucleotide (NADH) dehydrogenase subunit 1 gene. The prevalence of CE was 5.7% (337/5961). The 263 genotyped cysts belonged to E. equinus (n = 163), E. granulosus sensu stricto (n = 70), E. canadensis (G6/7) (n = 26) and E. ortleppi (n = 4). One donkey harboured a metacestode of Spirometra theileri. All E. equinus cases, except 2, originated from southern Ethiopia, whereas the other species were more evenly distributed across the study area. Most of the cysts belonging to E. equinus were fertile (111/163), while those of the other species were non-fertile. This is the first report of Echinococcus spp. in donkeys from sub-Saharan Africa and the first confirmation of E. equinus in East Africa. The frequent fertility of E. equinus cysts in donkeys affirms their suitability as intermediate hosts of this species, while low frequency and cyst fertility suggest a marginal role of donkeys in the transmission of E. granulosus s. s., E. canadensis (G6/7) and E. ortleppi.
More industrious and less austere than expected: evidence from inventories of agricultural workers in north-eastern Catalonia (1725–1807)
Authors: Congost Rosa , Ros Rosa , Saguer Enric 
Published: February 2023

AbstractThis article studies the changes in ownership of real estate, livestock and objects belonging to agricultural workers in the region of Girona, north-eastern Catalonia, through the analysis of a sample of nearly one thousand postmortem inventories dated between 1725 and 1807. It shows that a sizable number of agricultural workers gained greater access to property rights in land and other means of production, as well as undeniable improvements in their consumption levels during that period. Regarding the latter point, comparisons with inventories of the lower classes in Great Britain and other areas of north-western Europe show that the differences are not nearly as radical as suggested by the stereotype often applied to Mediterranean areas. The article thus discusses the apriorisms that have led many researchers to reject the idea that an industrious revolution was possible in southern Europe, and vindicates the need to strengthen dialogue between historiographies.

Behind the scene of the prevalence of anaemia: an extended way of reporting
Authors: Rahman Sabuktagin , Shaheen Nazma 
Published: February 2023

AbstractObjective:To develop the methods for an extended reporting of anaemia and to measure the status of the key contextual underlying factors of anaemia.Design:Statistical appraisal of Hb v. key influencers of anaemia in Bangladesh – the intake of animal source food (ASF), concentration of Fe in the drinking groundwater (GWI) and the prevalence of congenital Hb disorder (CH) are conducted. The primary data of the National Micronutrient Survey 2011–2012 and the British Geological Survey 2001 are analysed to assess the intake of ASF and the GWI concentration, respectively. The prevalence of thalassaemia from a national survey is used to appraise the CH. ASF is evaluated relative to the 97·5th percentile intake and group scores are assigned. Association of the GWI and Hb is examined by the linear fit and the mspline fit and the group scores are allocated. Group score is allocated for the prevalence of thalassaemia. Inflammation-adjusted ferritin is considered to report Hb.Setting:A nationwide survey in Bangladesh.Participants:Preschool children (6–59 months), school-age children (6–14 years) and non-pregnant non-lactating women (NPNLW, 15–49 years).Results:The extended reporting to the prevalence of anaemia in Bangladeshi preschool children, school children and women is – anaemia 33 % (ASF: 2·08; GWI: 1·75; CH: 2), anaemia 19 % (ASF: 1·98; GWI: 1·56; CH: 2) and anaemia 26 % (ASF: 2·16; GWI: 1·58; CH: 2), respectively.Conclusion:The extended reporting of anaemia is a useful tool to understand the status of the key influencers of anaemia, to design the context-customised intervention and to monitor the intervention.
