Authors: Baba Akira , Kurokawa Ryo , Kurokawa Mariko , Rivera-de Choudens Roberto , Srinivasan Ashok 
Published: June 2023

Abstract
Purpose
To evaluate and compare the utility of 40-keV virtual monochromatic imaging (VMI) reconstructed from dual-energy computed tomography (DECT) in the assessment of neck lymph node metastasis with 70-keV VMI, which is reportedly equivalent to conventional 120-kVp single-energy computed tomography.

Materials and methods
Patients with head and neck squamous cell carcinoma who had neck lymph node metastasis in contact with the sternocleidomastoid muscle (SCM) and underwent contrast-enhanced DECT were included. In 40- and 70-keV VMI, contrast differences and contrast noise ratio (CNR) between the solid component of neck lymph node metastasis (SC) and the SCM and between SC and nodal necrosis (NN) were calculated. Two board-certified radiologists independently and qualitatively evaluated the boundary discrimination between SC and SCM and the diagnostic certainty of NN.

Results
We evaluated 45 neck lymph node metastases. The contrast difference between SC and SCM and SC and NN were significantly higher at 40-keV VMI than at 70-keV VMI (p < 0.001). The CNR between SC and SCM was significantly higher at 40-keV VMI than at 70-keV VMI (p < 0.001). Scoring of the boundary discrimination between SC and SCM as well as the diagnostic certainty of NN at 40-keV VMI was significantly higher than that at 70-keV VMI (p < 0.001). The inter-rater agreements for these scores were higher at 40-keV VMI than at 70-keV VMI.

Conclusion
Additional employing 40-keV VMI in routine clinical practice may be useful in the diagnosis of head and neck lymph node metastases and nodal necrosis.

Authors: Ezeani Adaora , Tcheugui Justin B. E. , Agurs-Collins Tanya 
Published: June 2023

Abstract
Background
The purpose of this study was to assess the association of metabolic syndrome (MetS) and its individual components in cancer survivors (CS) by gender, in comparison to participants without a history of cancer who have at least one chronic disease (CD) and those without a chronic disease diagnosis (NCD).

Methods
Data from participants 40 years and older (n = 12,734) were collected from the 2011 to 2018 National Health and Nutrition Examination Survey dataset. MetS was defined based on the National Cholesterol Education Program’s Adult Treatment Panel III. Chi-square test and multivariate-adjusted logistic regression was used to assess group comparisons and associations respectively.

Results
Compared to NCD, CS and CD men had increased odds of meeting MetS, OR 2.60 (CI 1.75–3.87) and OR 2.18 (CI 1.59–2.98) respectively. For women, CS and CD participants also had higher odds of meeting MetS criteria compared to their healthy counterparts, OR 2.05 (CI 1.44–2.93) and OR 2.14 (CI 1.63–2.81) respectively. In subgroup analysis by cancer site, CS men with a history of hematologic malignancies (OR 4.88, CI 1.30–18.37) and CS women with cervical cancer (OR 4.25, CI 1.70–10.59) had highest odds of developing MetS, compared to NCD. CS men also showed a strong association with elevated waist circumference, low high density lipoprotein-c, and elevated triglycerides, even by cancer site, but there were no consistent findings among women.

Conclusion
This study indicates that CS men have a strong association with MetS, especially among those with blood-related cancers.

AbstractNanotechnology and nanostructured materials for drug delivery and tissue engineering applications are relatively new field that is constantly advancing and expanding. The materials used are at the nanoscale level. Recently, great discoveries and applications have been made (Agents for use in chemotherapy, biological agents and immunotherapy agents) in the treatment of diseases in various areas. Tissue engineering is based on the regeneration and repair of damaged organs and tissues by developing biological substitutes that restore, maintain or improve the function of tissues and organs. Cells isolated from patients are used to seed 3D nanoparticles that can be synthetic or natural biomaterials. For the development of new tissue in tissue engineering, it is necessary to meet the conditions for connecting cells. This paper will present the ways of connecting cells and creating new tissues. Some recent discoveries and advances in the field of nanomedicine and the application of nanotechnology in drug delivery will be presented. Furthermore, the improvement of the effectiveness of new and old drugs based on the application of nanotechnology will be shown.
Biphenotypic Sinonasal Sarcoma with Orbital and Skull Base Involvement Report of 3 Cases and Systematic Review of the Literature
Authors: Anastasiadou Sofia , Karkos Peter , Constantinidis Jannis 
Published: June 2023

AbstractBiphenotypic sinonasal sarcoma (BSNS) is a rare malignant tumour of the upper nasal cavity and ethmoid sinuses that presents predominantly in middle aged female patients and show a characteristic infiltrative and hypercellular proliferation of spindle cells that demonstrate a specific immunoreactivity. We present three cases with BSNS that had different presenting complaints, either sinonasal or orbital problems, underwent endoscopic surgical treatment and/or radiotherapy and have been disease free on long follow up. A systematic review of all published cases was performed to identify all BSNS cases known at present. BSNS requires prompt and correct diagnosis with accurate surgical resection as well as consideration of radiotherapy. Our three cases confirm the findings of the literature and support that BSNS is an aggressive but treatable malignant disease of the sinonasal tract.

Published: June 2023

AbstractHearth-pits are some of the most common archaeological features documented in open-air Mesolithic sites, especially in coversand areas of NW Europe. However, very few geoarchaeological studies have addressed their formation, function and relationship with occupation surfaces. This work introduces new interdisciplinary investigations on the sediments of the Mesolithic open-air site of El Arenal de la Virgen (SE Iberia). A selection of five hearth-pits from two different occupation phases (Phase 1: 9.3–9.1 cal ka BP and Phase 2: 8.6–8.3 cal ka BP) has been analysed using stratigraphy, texture, soil chemistry, micromorphology, petrography and OSL and TL analyses. Combustion traits of the carbonate rock assemblages preserved in the sediments of the hearth-pits have also been investigated and compared to reference and experimental data from local geogenic materials. Our results allowed us to discuss the anthropogenic origin and taphonomy of the hearth-pits studied and approach their function. The structures from Phase 1 are interpreted as a possible oven and a dumping feature linked to single/occasional use events. In contrast, for hearth-pits from Phase 2, we propose they were related to combustion and dwelling areas subject to recurrent occupation episodes and disturbance. Finally, our sedimentary and soil data revealed existing favourable paleoenvironmental conditions during the Mesolithic occupation of the site characterized by increased moisture, temperature and vegetation cover, in contrast to the Pleistocene and Middle Holocene periods pre- and post-dating the human settlement. This work highlights the potential of integrating geoarchaeological and contextual evidence to clarify the factors involved in the formation of hearth-pits and infer intra-site occupation patterns.

A﻿bstractObjectivesContentless experience involves an absence of mental content such as thoughts and perceptions. It is often described aspure consciousnessor complete stillness/silence, and is a goal in Shamatha, Thai Forest, and Stillness Meditation. This study examined the subjective character of the deepest experience of stillness/silence typically reported in each practice, and whether there are differences in reports across traditions.MethodEighty-four Shamatha, 80 Thai Forest, and 88 Stillness Meditation participants (Mlifetime hours practice = 2305; median = 671; range = 5–34,021) provided usable responses to an online questionnaire. Participants were presented with 48 types of mental content described as absent or present in traditional texts, including well-recognized forms of content such as thoughts and perceptions, and less obvious forms—referred to in this paper as abstract content—such as wakefulness, naturalness, calm, bliss/joy, and freedom. Participants indicated the extent to which each type of content was part of their deepest experience of stillness/silence during a specific retreat or during class and home practice.ResultsIn each tradition, participants typically reported a highly positive experience involving low awareness of content such as thoughts and perceptions, and a high degree of abstract content such as calm and mental relaxation. Across the practices, there were robust differences with respect to bliss/joy, wakefulness, absorptiveness, and depth.ConclusionsThe reported experiences are contentless in the sense that participants reported little awareness of content such as thoughts and perceptions. However, the experiences are not the states devoid of all content (and therefore identical to one another) that have been classically referred to in academic literature. These findings demonstrate the importance of examining contentless experiences in a fine-grained manner that takes into account abstract forms of content and assesses differences as well as similarities.

Published: June 2023

AbstractThe aim of this study is to define the importance of peritoneal CEA (pCEA) as a prognostic factor of overall survival (OS) and disease-free survival (DFS) in gastric cancer (GC) patients surgically treated with a curative intent In our department. A total of 64 patients affected by gastric cancer with intraoperatively measurement of CEA on peritoneal lavage were enrolled in the study. Patients were divided into two groups: (A) the peritoneal lavage CEA ( −) with CEA < 0.5 ng/ml and (B) the peritoneal lavage CEA ( +) with CEA ≥ 0.5 ng/ml. Then we analyzed OS and DFS of the two groups correlating them to others clinico-pathological features. Furthermore, we investigated the correlation between pCEA and peritoneal cytology. We demonstrated a strong significant difference in OS and in DFS in CEA ( +) patients. We emphasized that pCEA had a strong survival impact, in both OS and DFS, in selected patients affected by diffuse histotype GC (p = 0.0048 and p = 0.0030 respectively), stage III (p = 0.015 and p = 0.021, respectively) and distal gastric cancer (p = 0.0036 and p = 0.0017, respectively). There is a strong need to recognize prognostic factors that can help clinicians to stratify patients at high risk to develop post-surgical recurrences and moreover to recognize who could benefit from an aggressive surgical treatment of cytoreductive surgery and intra-peritoneal chemotherapy.pCEA is a good predictor of survival in advanced gastric cancer and could discriminate which patients need a more accurate follow-up program and an intensive therapeutic strategy.
Application of KRR, K-NN and GPR Algorithms for Predicting the Soaked CBR of Fine-Grained Plastic Soils

Published: June 2023

AbstractCalifornia bearing ratio (CBR) test is one of the comprehensive tests used for the last few decades to design the pavement thickness of roadways, railways and airport runways. Laboratory-performed CBR test is considerably rigorous and time-taking. In a quest for an alternative solution, this study utilizes novel computational approaches, including the kernel ridges regression, K-nearest neighbor and Gaussian process regression (GPR), to predict the soaked CBR value of soils. A vast quantity of 1011 in situ soil samples were collected from an ongoing highway project work site. Two data divisional approaches, i.e., K-Fold and fuzzy c-means (FCM) clustering, were used to separate the dataset into training and testing subsets. Apart from the numerous statistical performance measurement indices, ranking and overfitting analysis were used to identify the best-fitted CBR prediction model. Additionally, the literature models were also tried to validate through present study datasets. From the results of Pearson’s correlation analysis, Sand, Fine Content, Plastic Limit, Plasticity Index, Maximum Dry Density and Optimum Moisture Content were found to be most influencing input parameters in developing the soaked CBR of fine-grained plastic soils. Experimental results also establish the proficiency of the GPR model developed through FCM and K-Fold data division approaches. The K-Fold data division approach was found to be helpful in removing the overfitting of the models. Furthermore, the predictive ability of any model is considerably influenced by the geological location of the soils/materials used for the model development.
Electrochemically-stimulated nanoscale mechanochemical wear of silicon

Published: June 2023

AbstractMechanochemical reactions at the sliding interface between a single-crystalline silicon (Si) wafer and a silica (SiO2) microsphere were studied in three environmental conditions: humid air, potassium chloride (KCl) solution, and KCl solution with an applied voltage. Compared to that from humid air, mechanochemical material removal from the silicon surface increased substantially in the KCl-immersed condition, and further increased when electrochemistry was introduced into the tribological system. By measuring the load dependence of the material removal rate and analyzing the results using a mechanically assisted Arrhenius-type kinetic model, the activation energy (Ea) and the mechanical energy (Em), by which this energy is reduced by mechanical activation, were compared qualitatively under different environmental conditions. In the KCl-immersed condition, mechanochemistry may decrease the required effective energy of reactions (Eeff = Ea − Em) and promote material removal mainly through improved catalysis of the mechanochemical reactions facilitated by greater availability of water molecules compared to the humid air condition. Thus, the effectiveness of the mechanochemistry is improved. In the electrochemical condition, electrochemically-accelerated oxidation of the silicon surface was confirmed by the X-ray photoelectron spectroscopy (XPS) characterization. The results strongly suggest that electrochemistry further stimulates mechanochemical reactions primarily by increasing the initial energy state of the surface via the facilitated formation of interfacial bonding bridges, i.e., a surface oxidation/hydroxylation process.

Published: June 2023

AbstractFuzzy set (FS) theory and rough sets (RSs) are constructed to accommodate the data uncertainty. In contrast, the bipolar FS (BFS) theory can tackle the uncertainty and the bipolarity of the data in different circumstances. This article aims to introduce the idea of rough bipolar fuzzy ideals in semigroup (SG), which is a generalization of the concept of rough BFSs (RBFSs) in an SG. We also investigate the roughness in the bipolar fuzzy subsemigroup (BF-SSG) with the help of congruence relation (cng-R) defined on the SG and studied some relevant structural properties. Moreover, the idea is extended to the rough bipolar fuzzy left ideal, rough bipolar fuzzy right ideal, rough bipolar fuzzy two-sided ideal, rough bipolar fuzzy interior ideal, and rough bipolar fuzzy bi-ideal in SGs. Further, it is seen that cng-Rs and complete cng-Rs play vital roles in the construction of rough approximations of bipolar fuzzy ideals. Consequently, their associated properties are explored by using cng-Rs and complete cng-Rs.
Authenticity and Inauthenticity in Adolescents: A Scoping Review

Published: June 2023

AbstractIn everyday life, adolescents’ authenticity and inauthenticity (sense of, and being, the real me/true self; or false self/not the real me) are assumed to be general indicators of their psychosocial health as they navigate developmental processes of identity exploration and relational connectedness on their way to adulthood. Authenticity is important for psychological thriving in adolescents and inauthenticity is considered maladaptive, but there was no broad and systematic evidence-based resource on the topic. Therefore, this scoping review maps: (1) how authenticity and inauthenticity in adolescents (12–18 years old) have been understood, defined, and characterized; (2) what is known about authenticity and inauthenticity; (3) contexts authenticity and inauthenticity have been explored in; and (4) methodological approaches utilized. This review followed a pre-registered protocol (2852 records identified; 39 peer-reviewed primary research studies included). The review revealed authenticity and inauthenticity are typically: characterized as dispositional, involving thoughts, feelings, awareness, and a sense of being one’s true self or a false self; investigated quantitatively; and contextualized in close social relationships (parents, friends, classmates). Authenticity and inauthenticity outcomes included friendship quality, wellbeing, self-esteem, depressive symptoms, internet addiction, and moral disengagement. Adolescents’ authenticity generally increases over time and social support is very important for that process. Adolescents can be more authentic if parents facilitate adolescents’ increasing independence and support role experimentation. Future research should target state (here-and-now) authenticity, as a critical finding was that autonomy satisfaction has an immediate and positive influence on adolescents’ state authenticity, which implies people interacting with adolescents can promptly boost their capacity for positive psychological development.
Bayesian modeling via discrete nonparametric priors

Published: June 2023

AbstractThe availability of complex-structured data has sparked new research directions in statistics and machine learning. Bayesian nonparametrics is at the forefront of this trend thanks to two crucial features: its coherent probabilistic framework, which naturally leads to principled prediction and uncertainty quantification, and its infinite-dimensionality, which exempts from parametric restrictions and ensures full modeling flexibility. In this paper, we provide a concise overview of Bayesian nonparametrics starting from its foundations and the Dirichlet process, the most popular nonparametric prior. We describe the use of the Dirichlet process in species discovery, density estimation, and clustering problems. Among the many generalizations of the Dirichlet process proposed in the literature, we single out the Pitman–Yor process, and compare it to the Dirichlet process. Their different features are showcased with real-data illustrations. Finally, we consider more complex data structures, which require dependent versions of these models. One of the most effective strategies to achieve this goal is represented by hierarchical constructions. We highlight the role of the dependence structure in the borrowing of information and illustrate its effectiveness on unbalanced datasets.
Sour Grapes? Party Donors and Canadian Leadership Primaries
Authors: Pruysers Scott 
Published: June 2023

AbstractPolitical parties around the world are adopting primaries to select leaders and legislative candidates. While a large, though inconclusive, literature has emerged in the American context to explore the consequences of primaries, little attention has been devoted to other national contexts. Exploring patterns of financial donation, this study examines whether individuals who supported a losing leadership candidate are less likely to exhibit subsequent financial commitment to the party compared to those donors whose preferred candidate won the internal election. Drawing upon a novel dataset that includes tens of thousands of donors to recent leadership elections in Canada, we demonstrate that intra-party winners (i.e. those who supported the winning leadership candidate) are more likely to be financially committed to the party in the year after the election than those who supported losers. Results suggest that open and inclusive elections, while participatory in nature, may come at a cost for political parties as losers withdraw from the party in the wake of their loss.

Published: June 2023

AbstractThis is the first study reporting parasites from the freshwater cyprinidOxynoemacheilus angorae(Steindachner 1897) caught in Nilüfer Stream, Bursa, in the Northwest Anatolian Region of Turkey.Allocreadium bursensisn. sp. was described from the intesine ofO.angoraebased on morphological and genetic characteristics.Allocreadium bursensisn. sp. was differentiated from otherAllocreadiumspp. in having a combination of external (ventral and oral suckers ratio; body length and width and its ratio to forebody) and internal (cirrus pouch position; uterus extension in hindbody; egg size; disposition of anterior border of vitellarium; esophagus length) features. Phylogenetic hypotheses based on maximum parsimony, maximum likelihood, Bayesian inferrence, and neighbor joining analyses of sequence data strongly supported the hypothesis thatA. bursensisis nested within the clade ofAllocreadiumspecies hosted by cypriniform fish, and it is more closely related to the Far Eastern speciesA. pseudoisoporum(Primorsky region, Russia) than to the AfricanA. apokryfi.According to genetic p-distances, the taxonomic status of trematodes collected in Turkey was established as independent relative to nine of the validAllocreadiumspp.: 1.8–5.8% in 28S gene and 18.8–22.6% incox1gene. The present study increases the number ofAllocreadiumspecies and their definitive hosts recorded in Turkey and raises the number of Palearctic representatives ofAllocreadiumspp. to 26.
