Measurement of Diffusion Coefficients and Assessment of Atomic Mobilities in HCP Mg-Ag-Sn Alloys
Authors: Yang Yang , Zhu Lilong , Manuel Michele V. 
Published: June 2024

AbstractReliable thermodynamic and kinetic databases are essential for designing and developing novel magnesium (Mg) alloys for elevated-temperature applications in the automotive and aerospace industries. This study investigated diffusion behaviors of HCP Mg-Ag-Sn alloys by four sets of three diffusion couples annealed at 450, 500, and 550 °C, respectively. Interdiffusion and impurity diffusion coefficients at the three annealing temperatures were extracted using the forward-simulation method. The determined diffusion coefficients, combined with prior results in the literature, were then used to assess atomic mobilities for the HCP phase of the Mg-Ag-Sn system. This assessment was conducted using the DICTRA and the TCMG5 thermodynamic database within the Thermo-Calc software. Comprehensive comparisons between calculated and experimental diffusion coefficients yielded an excellent agreement. The atomic mobilities were also further validated by appropriate predictions of concentration profiles and diffusion paths observed in independent diffusion couple experiments performed at 525 °C for 18 hrs. It has been found that the addition of Sn and Ag both increase the diffusivity of Ag in HCP Mg and Sn in HCP Mg in the stable temperature range of HCP Mg, respectively. This improved understanding of the kinetics in the Mg-Ag-Sn ternary system is essential for controlling diffusion-dependent properties such as coarsening and, therefore, the mechanical properties of Mg-Ag-Sn alloys at elevated temperatures.
Phenolic profile, fatty acid and mineral composition with antioxidant, antibacterial, and enzyme inhibitor activities of different extracts from Erodium Cicutarium (L.) L’Hér. consumed as a vegetable in Kilis, Turkey

AbstractThis study aimed to explore the antioxidant activities, phenolic profile, fatty acid and mineral composition of the different extracts of Erodium cicutarium (L.) L’Hér. consumed as a vegetable in Kilis, Turkey. While catechine hydrate was the most abundant phenolic compounds in methanol, ethanol and diethyl ether extracts, it was chlorogenic acid in the water extract. Looking at the fatty acid profile, the amount of palmitic acid, one of the saturated fatty acids, was found to be high (34.30%), followed by stearic acid (5.10%). Total monounsaturated fatty acids are the second highest fatty acids. Total polyunsaturated fatty acids were determined as the third rank fatty acids. While the amount of linoleic acid, one of the total polyunsaturated fatty acids, was determined as 17.62%, the ratio of linolenic acid was determined as 9.60%. While the most calcium, magnesium and potassium were found among the 9 different mineral substances determined, respectively; the lowest element was found to be nitrogen. Looking at the results, it was determined that the plant is a high source of calcium (1078.503 mg/kg). Inhibitory effects against Pseudomonas aeruginosa ATCC 9027 were observed, with a zone diameter of 5.5 mm and 11 mm in methanol extract and diethyl ether extract, respectively. Ethanol and water extracts of E. cicutarium (L.) L.‘Hér. may be preferred as an alternative natural agent due to their amylase and tyrosinase activities. The results suggested that the E. cicutarium (L.) L.‘Hér. extracts may be useful for food and medicinal applications.
A 12-year overview of fertility preservation practice in Nordic pediatric oncology centers
Authors: Asadi-Azarbaijani Babak , Oskam Irma C. , Jahnukainen Kirsi 
Published: June 2024

Abstract
Purpose
Fertility preservation is the only option to safeguard fertility following gonadotoxic treatments. This study aimed to provide an updated status on fertility preservation for pediatric cancer patients in the Nordic countries.

Methods
A questionnaire consisting of 14 questions was sent to directors of 18 main pediatric oncology centers in the Nordic countries in 2010 and 2022. We received information regarding indications, guidelines, counseling, and available fertility preservation options.

Results
The response rates were 89% in 2010 and 72% in 2022. The results reveal an increase in clinical practice guidelines on fertility preservation for cancer patients, from 25% in 2010 to 70% in 2022. Counseling on fertility preservation options in 2022 was more specific and offered to most patients who fulfilled indications for fertility preservation (from 19 to 77%). Sperm cryopreservation continues to be the predominant fertility preservation method for pubertal boys in the Nordic countries. However, there has been a notable increase in the availability of testicular tissue preservation for prepubertal boys (0 to 62%). A similar increase in the offer of ovarian tissue preservation for prepubertal girls (0 to 92%) was observed among pediatric cancer patients.

Conclusions
The past decade has shown commendable advancements in fertility preservation for pediatric cancer patients in the Nordic countries.

Implications for Cancer Survivors
As fertility care evolves globally, continuous assessment of regional practices and challenges is imperative to enhance the quality of care and life for pediatric cancer survivors in the Nordic regions.
Analysis of Top 100 Articles Cited in Top Pain Journals: A Comprehensive Two Decade Bibliometric Analysis
Authors: Vij Kunal , Thomas John M. , Wan Leo , Chatim Ajay N. , Thomas George , Kaye Alan D. 
Published: June 2024

Abstract
Purpose of Review
A bibliometric analysis was performed to analyze and compare the top 100 articles from the most well-known five pain journals: Pain, Pain Physician, Pain Medicine, Regional Anesthesia & Pain Medicine, and Journal of Pain. A query of the Scopus database was performed to filter the top 200 most cited articles from each journal. CY score was calculated for the top 200 articles from each journal by dividing the total number of citations by the number of years the article has been published.

Recent Findings
All articles had a collective analysis of the top CY scores, the top 100 of which were further analyzed. The pain subtype, type of publication, country of origin, and senior author were extrapolated from these top 100 articles. Frequency tables were organized, revealing Pain Journal as the highest publishing journal out of the top 100 articles.

Summary
Chronic pain was the most studied subtype of pain and narrative reviews were the most common type of evidence. Studies were also organized in five-year epochs to analyze the frequency of publications in these intervals. Results show that 2010-2014 had the highest frequency of articles published overall. Journal Impact Factor (JIF) is also an objective indicator of the average number of citations per published article from each journal. The journal with the highest JIF was Pain with an impact factor of 7.926. (6)
Environmental Factors Influencing Metal Concentrations in Scomber colias Along the Canary Islands

Published: June 2024

AbstractA total of 140 specimens of Scomber colias were collected from the Canary archipelago waters during the first semester of 2021, with 20 samples from each of the seven main islands. After analyzing the concentrations of metals (Al, Zn, Cd, Pb, Fe, and Cu) with ICP-OES, significant variations were observed among islands, with specimens from Tenerife and Gran Canaria containing higher levels of Al, Cd, and Pb, while those from Lanzarote and Fuerteventura had elevated levels of Zn, Fe, and Cu. These differences are probably related to greater anthropogenic activity around Tenerife and Gran Canaria coasts, leading to higher pollution levels, and the influence of Saharan dust and African upwelling on Lanzarote and Fuerteventura, enriching the waters with nutrients. Specific management strategies to mitigate marine pollution and continuous monitoring are crucial to safeguard marine ecosystems and to ensure food security.

Abstract
Introduction
The incidence of gastroenteropancreatic neuroendocrine tumors (GEP-NET) has steadily increased. These tumors are considered relatively indolent even when metastatic. What determines survival outcomes in such situations is understudied.

Materials and Methods
Retrospective analysis of a prospectively maintained NET clinic database, to include patients of metastatic grade 1 GEP-NET, from January 2018 to December 2021, to assess factors affecting progression-free survival (PFS).

Results
Of the 589 patients of GEP-NET treated during the study period, 100 were grade 1, with radiological evidence of distant metastasis. The median age was 50 years, with 67% being men. Of these, 15 patients were observed, while 85 patients received treatment in the form of surgery (n = 32), peptide receptor radionuclide therapy (n = 50), octreotide LAR (n = 22), and/or chemotherapy (n = 4), either as a single modality or multi-modality treatment. The median (PFS) was 54.5 months. The estimated 3-year PFS and 3-year overall survival rates were 72.3% (SE 0.048) and 93.4% (SE 0.026), respectively. On Cox regression, a high liver tumor burden was the only independent predictor of PFS (OR 3.443, p = 0.014). The 5-year OS of patients with concomitant extra-hepatic disease was significantly lower than that of patients with liver-limited disease (70.7% vs. 100%, p = 0.017).

Conclusion
A higher burden of liver disease is associated with shorter PFS in patients with metastatic grade I GEP-NETs. The OS is significantly lower in patients with associated extrahepatic involvement. These parameters may justify a more aggressive treatment approach in metastatic grade 1 GEP-NETs.
Attitudes Toward Mononormativity and Polyamorous Legal Rights in the US
Authors: Morris Georgia , Chen Li Yin , Kaufman Gayle , Compton D’Lane 
Published: June 2024

Abstract
Introduction
Recent research shows an increase in polyamory and acceptance of polyamorous relationships. However, there is still limited research on broader attitudes toward monogamy and polyamory, particularly regarding legal rights and with a national sample. This study examines the impact of cohort, sexual orientation, and contact with polyamorists on attitudes toward monogamy and polyamorous legal rights. This research has the potential to bring more attention to polyamorous relationships, disrupt heteronormative views of relationships, and consider legal rights for those in relationships involving more than two people.

Methods
We use data from a sample of 2665 adults from the 2021 American Marriage Survey, a national survey focused on attitudes toward marriage post-marriage equality, to consider the relationship between cohort, sexual orientation, contact, and attitudes toward mononormativity and polyamory.

Results
Overall, there is support for the idea that monogamy is the norm while people are generally not supportive of granting legal rights for polyamorous relationships. Younger cohorts, LGBQ individuals, and those who know a polyamorous person are less likely to support mononormativity and more likely to support legal rights for polyamorous relationships. Furthermore, contact has a stronger impact on attitudes of Millennials and LGBQ individuals.

Conclusion
While mononormativity remains the norm and polyamory is not widely supported, given patterns of greater acceptance among younger cohorts and LGBQ individuals, there is a good possibility that acceptance will increase over time.

Policy Implications
This research has the potential to bring more attention to polyamorous relationships, disrupt heteronormative views of relationships, and consider legal rights for those in relationships involving more than two people.
Adsorptive removal of hazardous rhodamine B dye from aqueous solutions by St. John’s wort (Hypericum perforatum)
Authors: Isik Birol 
Published: June 2024

AbstractIn this work, it was aimed to remove the highly toxic rhodamine B (RhB) dye from wastewater by using a low-cost, renewable, sustainable, and completely natural adsorbent obtained from St. John’s wort (Hypericum perforatum) (HP), which is considered an agro-waste. HP was characterized by FTIR-ATR, XRD, FESEM, and pHpzc. Adsorption experiments were conducted by optimizing pH (2–12), dose (0.01–0.30 g), time (0–120 min), and concentration (10–50 mg/L). Equilibrium data were applied to linear isotherms. The results stated that the removal process occurred in a monolayer on the homogeneous surface of HP and the $${q}_{m}$$

AbstractAdditive manufacturing (AM) is very promising for the fabrication of complex parts made from shape memory alloys (SMAs). In the present study, a Ni–Ti–Hf shape memory alloy has been processed by laser beam powder bed fusion of metals (PBF-LB/M). Employing different sets of processing parameters, i.e., a variation of scanning speed, specimens characterized by various microstructures and porosities were obtained. Microstructural analysis revealed that processing of Ni–Ti–Hf SMAs at a low energy level promotes the formation of a fine-grained microstructure with numerous lack of fusion defects. Transmission electron microscopy (TEM) studies revealed that H-phase precipitates are present in any case, leading to an increase in the Ms-temperature and, thus, a phase transformation at room temperature. The thermal stability of the phase transformation behavior in different Ni–Ti–Hf as-built conditions was studied using differential scanning calorimetry (DSC). DSC analysis showed that specimens with a higher defect density are characterized by smaller thermal hysteresis.
From Monsters to Mazes: Sociotechnical Imaginaries of AI Between Frankenstein and Kafka
Authors: Dishon Gideon 
Published: June 2024

AbstractThe emergence of ChatGPT and other Generative AI tools (GenAI) capable of producing human-like texts sparked debates concerning whether we are at the dawn of a new age of writing and meaning-making. Rather than weighing in on the potential impact of GenAI, this paper engages with the implicit sociotechnical imaginaries underpinning reactions to GenAI. One particularly evocative source for sociotechnical imaginaries are fictional texts, which can shape our shared imagination of possible and probable futures. Accordingly, I analyze two seminal works of fiction: Mary Shelley’s Frankenstein (Planet eBooks, 1818) and Franz Kafka’s The Trial (Echo Library, 1925). Frankenstein is regarded as an enduring myth that has shaped perceptions of artificial life. This paper sets out to explore the limitations of the ‘Frankensteinian sociotechnical imaginary’ by unpacking AI’s assumed modes of meaning-making along three axes: (1) agency, (2) relations, and (3) control. Within the Frankensteinian sociotechnical imaginary, AI is approached in anthropomorphic terms, emphasizing the struggle over control of meaning-making without reshaping its overarching logic. The Trial, in contrast, offers a lens that challenges common dichotomies underpinning the Frankenstein model: (1) highlighting the entanglement between AI and human intentionality in processes of meaning-making, (2) exploring human-AI relations as recursively shaped through the complementary tendency of humans and GenAI to generate and infer meaning, and (3) shifting the notion of control from a struggle over domination to an emphasis on how GenAI concurrently expands the available choices while limiting humans’ influence over patterns of meaning-making.

AbstractThe aim of the current study was to determine the fracture toughness of different zones in carburized Pyrowear 53 steel using the small punch test (SPT) method. Firstly, Pyrowear 53 steel was quenched and tempered using different processing parameters to obtain core materials with varied microstructures and fracture toughness. The results obtained for the core material in standard fracture toughness tests were then compared with the SPT results, which allowed the determination of a formula correlating the fracture energy integral,JSPT, from the SPT withJQintegrals obtained from standardized compact tension specimens. In the next stage, Pyrowear 53 steel was carburized at 925 °C and divided into the following zones: (1) a carburized layer (up to 0.5 mm from the surface), (2) a transition layer (from 0.5 to 1.5 mm), and (3) a core zone (more than 1.5 mm). Each zone was characterized in terms of its microstructure and tensile properties using miniaturized test specimens. Finally, the fracture toughness values of the core zone (JSPT = 78–102 kJ/m2), the transition layer (JSPT = 71–80 kJ/m2), and the carburized layer (JSPT = 8.1–9.1 kJ/m2) were determined based on the obtained SPT results. It was shown that the use of such a relatively simple SPT method with the proposed energy-based approach seems to be a promising way of determining the fracture toughness of thin layers or local changes in the fracture behavior of surface-treated materials.

AbstractRecent years witnessed an increase in attention to femicide, or the killing of women because of their gender. Prior empirical studies have drawn attention to the prevalence of female homicide victimization, but most have been unable to give a detailed overview of the specific contexts in which women are killed, and to what extent female homicide victimization is unique, i.e., in that it differs from male victimization. This exploratory study aims, first, to map the nature and scope of female homicide in six European countries: Denmark, Finland, France, the Netherlands, Sweden and Switzerland; and, secondly, to compare female homicide victimization with male homicide victimization. Using data from a new uniform homicide recording system, the European Homicide Monitor, this study allowed for unique cross-country comparisons and a detailed breakdown by victim-offender relationship, and type of homicide. Results indicated that female homicide victimization rates remained relatively stable during the last decade, with a narrowing gender gap. Furthermore, results reflected substantial heterogeneity in the context in which women were victimized. Finally, female homicide victimization differs in many respects from male victimization, but overlaps do exist. Such heterogeneity, and possible overlaps with male victimization call for differential approaches.
Molecular symmetry change of perfluoro-n-alkanes in ‘Phase I’ monitored by infrared spectroscopy
Authors: Araki Taisuke , Oka Takayuki , Shioya Nobutaka , Hasegawa Takeshi 
Published: June 2024

AbstractPhase diagram of polytetrafluoroethylene (PTFE) comprises four regions. Phases II and IV are characterized by twisted perfluoroalkyl (Rf) chains having different twisting rate of 13/6 and 15/7, respectively, while Phase III is characterized by a planer trans-zigzag molecular skeleton like a normal alkyl chain. These are confirmed by X-ray and electron diffraction and have already been established. Unlike these, Phase I is left an unresolved matter. This phase is complicated indeed and is not symbolized by a single molecular structure. At an ambient pressure, Phase I is the temperature region above 30 ºC (303 K), and the helical molecular structure is supposed to be gradually untwisted with an elevating temperature. This untwisting image is roughly suggested by the diffraction, neutron scattering, and thermal expansion techniques, but the conventional approaches have all experimental limitations because the untwisting accompanies disorder (or defect) in the twist along the chain. To explore the transition between two different helical structures of the Rf chain having disordered structures, vibrational spectroscopic techniques are expected to be an alternative approach. For infrared spectroscopy, for example, the twisting rate of the molecule is simply recognized as a degree of molecular symmetry. Here, we show that the band progression peaks of the CF2 symmetric stretching vibration mode are quite sensitive and useful for pursuing the molecular symmetry change in Phase I for both peak intensity and position using perfluoro-n-alkanes having different chain length covering both even and odd number of the CF2 groups.
