Analytical validation and quality control/quality assurance practices for improved rigor and reproducibility of biochemical assays in orthopaedic research
Authors: Andress Benjamin , Hoffman Maureane , McNulty Amy L. 
Published: December 2022

AbstractOrthopaedic research, and biomedical research in general, has made enormous strides to develop treatments for conditions long thought to be inevitable or untreatable; however, there is growing concern about the quality of published research. Considerable efforts have been made to improve overall research quality, integrity, and rigor, including meaningful proposals focused on transparency of reporting, appropriate use of statistics, and reporting of negative results. However, we believe that there is another key component to rigor and reproducibility that is not discussed sufficiently—analytical validation and quality control (QC). In this commentary, we discuss QC and method validation principles and practices that are systematically applied in the clinical laboratory setting to verify and monitor the analytical performance of quantitative assays, and the utility of applying similar practices to biochemical assays in the orthopaedic research setting. This commentary includes (1) recommendations for validation and QC practices, including examples of assay performance limitations uncovered by validation experiments performed in our laboratory, and (2) a description of an ongoing QC program developed to monitor the ongoing performance of commonly used assays in our lab. We hope that this commentary and the examples presented here will be thought‐provoking and inspire further discussion and adaptation of analytical validation and QC procedures to advance our shared pursuit of high‐quality, rigorous, and reproducible orthopaedic research.
A Raman spectral database of naturally aged plastics: A proof‐of‐concept study for waste plastic sorting
Authors: Marica Ioana , Pînzaru Simona Cîntă 
Published: December 2022

AbstractA Raman spectral database of naturally aged plastics for years is developed aiming to support efficient and proper plastic waste management based on Raman sorting technology. The database is designed as a website and contains the Raman spectral data for 146 plastic waste samples degraded for years in natural environmental conditions. Plastic samples aged for years in indoor conditions are also included along with a few undegraded, common plastics. The natural environmental degradation occurring for years of exposure to sun radiation, terrestrial and aquatic factors, or temperature variations is poorly understood in terms of spectral changes of representative plastics. The samples of choice are represented by the widespread types of plastics such as polyethylene terephthalate, high‐density polyethylene, low‐density polyethylene, polyvinyl chloride, polypropylene, and polystyrene. Each plastic sample is described individually on the database's website, and its Raman spectrum is available as a txt file for both educational and analytical purposes. Moreover, the database was validated by external validation of the machine‐learning classifiers: k‐nearest neighbor, support vector machine, logistic regression, random forest, and Naïve Bayes resulting in a classification accuracy between 0.902 and 0.973.

AbstractAiming at the use of glass fiber reinforced poly‐ether‐ether‐ketone (GF/PEEK) with low laser absorbance in laser assisted tape winding/placement (LATW/LATP), a method for dyeing GF/PEEK prepreg with nanoparticle fillers (NFs) is presented. First, the effects of carbon black (CB) and graphite (G) NFs on composites laser absorbance and reflection pattern were quantified, and the complex refractive index model was derived. Next, the effects of NFs on composites transverse thermal conductivity were tested, and the accuracy of four thermal conductivity prediction models were compared. Finally, the effects of NFs on composites interlayer performance were studied. The optical test results showed that NFs could improve laser absorbance while not changing reflection pattern, and the increase rate of absorbance for CB was higher than for G. As calculated by complex refractive index model, GF/PEEK with 1‐layer thickness could achieve complete laser absorption by addition of either 2.74%CB or 3.78%G. The thermal conductivity test results showed that NFs could improve composites transverse thermal conductivity. The increase rate of thermal conductivity for G was higher than for CB. Among the four prediction model, the Lewis‐Nielsen model had correct prediction regularity and was within 10% predict deviation. Based on this model, the transverse thermal conductivity of GF/PEEK/2.74%CB was 0.557 W/m K, and of GF/PEEK/3.78%G was 0.592 W/m K. The mechanical test results showed that the CB loading ≤4% had little effect on interlayer performance, while the G decreased interlayer performance. Consequently, adding CB at a low loading is a better way to realize GF/PEEK application in LATW/LATP.

Published: December 2022

Abstract‘CP 14‐1934’ (Reg. no. CV‐210, PI 700310) sugarcane cultivar, a complex hybrid of Saccharum spp., was developed through cooperative research of the USDA‐ARS, the University of Florida, and the Florida Sugarcane League. The Florida Sugarcane Variety Committee released CP 14‐1934 in June 2021 for commercial cultivation on organic (muck) soil. CP 14‐1934 originates from a cross CPX11‐1041 between CP 07‐2460 (female parent) and CP 06‐2335 (male parent). CP 14‐1934 was released due to its high cane yield; high sucrose yields; acceptable commercial recoverable sucrose; and resistance to brown rust (tested positive to Bru1 marker), orange rust, sugarcane mosaic virus strain E (mosaic), and ratoon stunting disease. CP 14‐1934 was found moderately resistant to leaf scald and to have intermediate freeze tolerance. Based on results of three harvests cycles over five locations in final‐stage replicated yield trials (Stage 4) on muck soils, CP 14‐1934 cane and sucrose yields were 17.8 and 19.8% greater than the mean of reference cultivars, respectively. CP 14‐1934 rarely flowers in Florida's climate. The new released cultivar CP 14‐1934 is expected to increase the profitability and the efficiency in the use of resources of Florida sugarcane growers.

AbstractAround 40 years have passed since the first pioneering works introduced the possibility of using quantum physics to enhance communications safety. Nowadays, quantum key distribution (QKD) exited the physics laboratories to become a mature technology, triggering the attention of States, military forces, banks, and private corporations. This work takes on the challenge of bringing QKD closer to a consumer technology: deployed optical fibers by telecommunication companies of different States have been used to realize a quantum network, the first‐ever connecting three different countries. This work also emphasizes the necessity of networks where QKD can come up besides classical communications, whose coexistence currently represents the main limitation of this technology. This network connects Trieste to Rijeka and Ljubljana via a trusted node in Postojna. A key rate of over 3 kbps in the shortest link and a 7‐hour‐long measurement demonstrate the system's stability and reliability. The network has been used to present the QKD at the G20 Digital Ministers' Meeting in Trieste. The experimental results, together with the interest that one of the most important events of international politics has attracted, showcase the maturity of the QKD technology bundle, placing it in the spotlight for consumer applications in the near term.
Efficient Spin‐Direction Coupling between Circular Polarized Electric and Magnetic Dipoles and Photonic Modes

Published: December 2022

AbstractIntegrated single photon sources are essential elements in quantum computing, simulation, communication, and photonic neural networks. The directional radiation and scattering of single‐photon sources play a crucial role in light manipulation and rely on electric and magnetic dipole moments. Although clever physical insights and designer intuition strategies have been successfully applied in the development of integrated sources, inverse strategies could enhance and maximize its performance. Recently, topology‐optimized couplers for on‐chip single‐photon sources are designed to efficiently couple a guided mode and an electric dipole. However, the superposition of orthogonal electric and magnetic dipoles can also be harnessed due to the additional degrees of freedom via their interference. Here, the authors have extended the strategy to couplers that enhance spin‐direction coupling of circularly polarized, Huygens, and Janus dipoles. The authors demonstrate that optimization not only increases the coupling to a desire mode but also enhances the electric and magnetic local density of states (LDOS) while maintaining the amplitude and phase relation between the orthogonal dipoles for unidirectional coupling. Currently, coupling efficiency and enhanced LDOS of up to 88%, 94%, and 93% and up to 9.4, 18.6, and 14.9 are obtained for these dipoles. The topology optimization improves the performances of 3D integrated photonic devices.

Published: December 2022

AbstractIconic events have traditionally instigated progression in the fields of crisis and disaster science. In the wake of the COVID‐19 pandemic, the pressing question is how this global health emergency impacted the research agendas of our field. We reviewed contributions in ten important crisis and disaster journals in the two and a half years following the COVID‐19 outbreak from 1 January 2020 to 30 June 2022. Specifically, we conducted a bibliometric review using thematic mapping analysis to distill the major themes covered by the emerging COVID‐19 literature within crisis and disaster science (N = 239 articles). Our results indicate that several well‐known topics are applied to the COVID‐19 pandemic, such as risk, crisis communication, governance, resilience and vulnerability. The pandemic also gave rise to new topics, such as citizen behavior, state power, and the business and mental health impact of crisis measures. Several studies are already looking ahead by identifying lessons for preparedness and mitigation of future pandemics. By taking stock of the surge of COVID‐19 studies while this academic literature is still taking shape, this review sets the stage for future contributions to the crisis and disaster literatures. It provides valuable lessons for what topics are studied and what themes need more attention. The COVID‐19 pandemic is destined to become an iconic event for our literature that not only strengthens and deepens existing debates, but also clearly offers the opportunity to draw in new perspectives and broaden the horizon of crisis and disaster science.
A direct analysis method to globalh‐stability of delayed time‐varying nonlinear positive systems
Authors: Cao Shuhao , Zhang Xian , Tianqiu Yu 
Published: December 2022

SummaryThis paper focuses on the global ‐stability of the nonlinear positive system with multiple time‐varying delays. Through differentiated expressions of the function , the global ‐stability could be referred to as several known stabilities, including Lagrange stability, asymptotic stability, global exponential stability, global practical stability, and so forth. By proposing a direct analysis method that differs from the so‐called Lyapunov‐Krasovskii functional method, we presented a sufficient condition for the global ‐stability of such system. The obtained stability condition appeared in the form of a number of simple inequalities, which could be easily handled by the toolbox YALMIP loaded in MATLAB. The applicability of our results have been illustrated by three numerical examples.
Designing regional industrial symbiosis networks: The case of Apulia region
Authors: Giannoccaro Ilaria , Zaza Valeria , Fraccascia Luca 
Published: December 2022

AbstractAdopting industrial symbiosis (IS) is a key strategy for pursuing sustainable development and developing circular economy. In this regard, a powerful approach is promoting the development of regional business networks of IS relationships (ISNs), such as the well‐known Kalundborg ISN in Denmark. Nevertheless, a formalized method supporting the development of effective ISNs at the regional level is still lacking in the literature and practice. This paper develops a methodology to support the design of regional ISNs, consisting of two steps: (1) building a waste‐input relationship table, which can be used as a dictionary of the potential IS synergies implementable among couples of companies; and (2) identifying and selecting the potential symbiotic synergies that can be implemented among the companies belonging to a given regional area. The proposed methodology is tested for the case of Apulia region (Southern Italy), where more than 300 feasible IS synergies are identified. The method is useful both for companies interested to exploit IS benefits, and also for regional policymakers prone to develop IS in practice.
Informality and poverty in Africa: Which comes first?
Authors: Bolarinwa Segun Thompson , Simatele Munacinga 
Published: December 2022

AbstractExisting empirical work has investigated the relationship between informality and poverty. However, most of this work has neglected the feedback effect. This empirical paper explores the bi‐directional causality between poverty and informality within the SGMM‐PVAR framework among 40 selected high‐income and low‐income Sub‐Saharan countries between 1991 and 2018. Our results support the heterogeneity argument, suggesting that sub‐Saharan African informality is demand and supply‐led. The income level of the country mediates the direction of effect. Bi‐direction causality is observed for low‐income countries. Causality in middle‐income countries runs from poverty to informality. The results suggest that a certain level of informality may be desirable, especially in low‐income countries.
Anthrone‐Benzothiazole Based Heterocyclic Disperse Azo Dyes: Synthesis, Dyeing, UV Protection Property, Anti‐Bacterial Activity, and Computational Study
Authors: Patil Praful S. , Gupta Puja O. , Sekar Nagaiyan 
Published: December 2022

AbstractAnthrone and benzothiazole based disperse azo dyes (5a–5e) are synthesized and well characterized. These dyes are further applied to nylon, polyester, and acrylic fabrics. Fastness properties, including light, wash, and rub for dyed fabrics, were studied and found to be better for polyester and nylon than the acrylic substrate. Better sublimation fastness was obtained on polyester than nylon at 210 °C. The “ultraviolet protection factor (UPF)” of all dyed fabrics was detected to block ultraviolet radiation (UVR) in the range of 93 to 97 percent. Nylon and acrylic dyed fabric were excellent, while polyester showed good ultraviolet protection activity. All the dyes are effective towards “(S. aureus) gram +ve” and “(K. pneumoniae) gram −ve” bacteria. The textile dyed with the dye obtained from the diazotized 2‐amino‐6‐methyl‐benzothiazole and anthrone (5b) was found to have ≥99 % potent inhibition. The HOMO‐LUMO energy gap and other quantum chemical descriptors such as softness, hardness, and electrophilicity index are obtained from the “density functional theory (DFT)” computations.

Published: December 2022

Abstract2D materials have captured much recent research interest in a broad range of areas, including electronics, biology, sensors, energy storage, and others. In particular, preparing 2D nanosheets with high quality and high yield is crucial for the important applications in energy storage and conversion. Compared with other prevailing synthetic strategies, the electrochemical exfoliation of layered starting materials is regarded as one of the most promising and convenient methods for the large‐scale production of uniform 2D nanosheets. Here, recent developments in electrochemical delamination are reviewed, including protocols, categories, principles, and operating conditions. State‐of‐the‐art methods for obtaining 2D materials with small numbers of layers—including graphene, black phosphorene, transition metal dichalcogenides and MXene—are also summarized and discussed in detail. The applications of electrochemically exfoliated 2D materials in energy storage and conversion are systematically reviewed. Drawing upon current progress, perspectives on emerging trends, existing challenges, and future research directions of electrochemical delamination are also offered.

Published: December 2022

AbstractA numerical analysis of MHD 3D second grade fluid over slendering stretching sheet is presented in this study. In addition, heat generation and thermal radiation impacts are included to inspect the heat transfer mechanism. Using the boundary layer approximation, the problem is stated mathematically in the form of PDEs (partial differential equations), which are altered to nonlinear ODEs (ordinary differential equations) by invoking appropriate similarity variables. Solutions of these nonlinear equations are computed by MATLAB bvp4c function. Graphs for involving parameters are plotted to view their impacts on velocity and temperature. Impression of numerous parameters on Skin friction and Nusselt number are also depicted in tables and the results are discussed in detail. The computed values of skin friction revealed constant behavior and Nusselt number depicted increasing performance due to boosting values of Prandtl number Pr. The computed values of skin friction revealed constant behavior and Nusselt number depicted reducing performance due to boosting values of heat generation parameter Q. The computed values of skin friction revealed constant behavior and Nusselt number depicted reducing performance due to boosting values of radiation parameter Rd.
Defining Finland’s Cultural Diplomacy from Postwar to Cold War
Authors: Clerc Louis 
Published: December 2022

AbstractCultural diplomacy, as a dimension of the state’s cultural and foreign policy, refers to specific actions planned, coordinated or organized by central public institutions, aiming to support the objectives of the state. But the objectives of any state’s policy are rarely an object of domestic consensus: they might be disputed in society, and different emphases might be found even inside the state’s organizational frame. An important starting point in our search for Finland’s cultural diplomacy is thus to find the various reasons for which Finnish administrators would engage in and develop a cultural diplomacy. Discussing these elements in the context of the Cold War, one has to consider both the weight of the bipolar divide on any policy undertaken by the Finnish state, as well as the local context. Arguments in favor of state-led cultural outreach overseas showed a certain consistency over the three decades studied here, with concerns expressed immediately after the war and continuing up to the 1970s. This continuity was also the result of continuities in personnel, with roughly the same individuals dealing with international cultural relations inside the Finnish civil service. They developed a number of rationales for cultural diplomacy, between supporting Finland’s foreign policy in a difficult geopolitical situation, modernizing Finnish society through curated foreign examples and an opening up to global cultural trends, promoting a new image of the country abroad, supporting trade or participating in the work of international organizations.
Developing State Agencies and Centralizing International Cultural Relations
Authors: Clerc Louis 
Published: December 2022

AbstractIn 1968, Kalervo Siikala sent the Finnish Minister for Education Johannes Virolainen a long plaidoyer for a state-funded cultural policy with an ambitious international outreach. He emphasized the developments that had happened since the war in Finland’s international contacts and criticized what he saw as a Finnish cultural field still locked under hierarchical, conservative private cultural organizations, dominated by conservative elites, old-fashioned institutions, and defiance towards the Eastern bloc. Siikala wanted a new, dynamic, open and democratic cultural policy, with a stronger role for the Finnish state to coordinate private organizations and steer their activities towards the country's official foreign policy line and the goals of Finland's developing welfare state. It had to emphasize the interest of the youth and young people, who wanted to get rid of old hierarchies, and adapt cultural policy to a geopolitical context dominated by Soviet influence. Siikala stopped short of proposing a fully state-controlled cultural field, but demanded better instruments to coordinate private initiatives by public resources: “cultural life has to develop its own organic way and find its own direction”, he wrote, although it had to do so “in those limits set by the possibilities and needs of society and economic life”. In an environment dominated by ideas of cultural reform and the influence of a new radical left, the Ministry of Education should be given the possibility to lead the cultural field. The problem was also political: to maintain good relations with the USSR demanded stronger state coordination also in cultural matters.
