Review
The myelodysplastic syndromes/myeloproliferative neoplasms (MDS/MPN) category comprises a varied group of myeloid neoplastic diseases characterized by clinical and pathologic overlapping features of both myelodysplastic and myeloproliferative neoplasms. For these reasons, these tumors are challenging in terms of diagnosis. The recent World Health Organization (WHO) 2022 classification and the International Consensus Classification (ICC) made changes in the classification of MDS/MPN compared to the previous 2016 WHO classification and improved the diagnostic criteria of these entities. The aim of this review is to describe the main entities reported in the more recent classifications, focusing on chronic myelomonocytic leukemia (CMML), MDS/MPN with neutrophilia (or atypical CML [aCML]), and MDS/MPN with mutation and thrombocytosis/MDS/MPN with ring sideroblasts and thrombocytosis. A particular emphasis is given to the differential diagnosis and analysis of subtle divergences and semantic differences between the WHO classification and the ICC for these entities.

Review
The aim of this paper is to provide information regarding diversity in speech and language profiles of individuals with Autism Spectrum Disorders (ASD) and try to classify these profiles according to the combination of the communication difficulties. Research findings confirm the existence of heterogeneity of communication challenges in ASD across the lifespan. A lot of children with ASD experience communication challenges and strengths across all language sub-systems including pragmatics, grammar, semantics, syntax, phonology, and morphology in both oral and written language, while some children with autism demonstrate exceptional language abilities incl. linguistic creativity. Communication issues vary on a continuum of severity so that some children may be verbal, whereas others remain non-verbal or minimally-verbal. The diversity of profiles in speech and language development stem from either the presence of comorbid factors, as a core symptom of autistic behavior without comorbidity or both, with the development of complex clinical symptoms. Difficulties with the semantic aspect of language affect the individual's skills in abstract thinking, multiple meanings of words, concept categorization, and so on. Finally, the coexistence of ASD with other communication difficulties such as a Language Disorder, Apraxia of Speech, Speech Sound Disorders or/and other neurodevelopmental disorders raises the need for examining more carefully the emergence of new clinical profiles and clinical markers useful in performing differential diagnosis and different intervention.

A Randomized Controlled Clinical Trial of Pulpotomy versus Root Canal Therapy in Mature Teeth with Irreversible Pulpitis: Outcome, Quality of Life, and Patients' Satisfaction.
INTRODUCTION
Vital pulp therapy is increasingly practiced as an alternative treatment to root canal therapy (RCT) in teeth with carious pulp exposure. The aim of this study was to compare the outcome, quality of life (QOL), and patients' satisfaction after full pulpotomy and RCT in mature teeth with irreversible pulpitis.
METHODS
Sixty mature permanent molar teeth with carious pulp exposure and a diagnosis of irreversible pulpitis were randomly divided into 2 groups (n = 30). The first group was treated with full pulpotomy using Biodentine (Septodont, Saint Maur des Fosses, France), and the second group was treated with RCT. The pain level was recorded preoperatively and at 1, 2, 3, 5, and 7 days. Clinical and radiographic assessments were performed at the 6- and 12-month follow-ups; 1 case in each group did not attend. Based on the Oral Health Impact Profile questionnaire and 7 semantic differential scales, QOL, and patients' satisfaction were evaluated and compared statistically.
RESULTS
Pulpotomy and RCT had comparable success rates (27/29, 93%). Pain levels at day 1 after pulpotomy were significantly lower than after RCT (P = .037), less patients required analgesics (P = .028), and pulpotomy provided pain relief in a shorter time compared with RCT. Both treatments improved the Oral Health Impact Profile QOL of patients without significant differences (60.29, 64.1% at 1 year). Patients' satisfaction with pulpotomy was higher than RCT in terms of the time involved, intraoperative pain, pleasantness, and cost (P < .05).
CONCLUSIONS
Full pulpotomy could be an alternative treatment to RCT in mature teeth with carious pulp exposure and symptomatic irreversible pulpitis based on the clinical and radiographic success rates and patients' satisfaction.

Review
Word embeddings provide quantitative representations of word semantics and the associations between word meanings in text data, including in large repositories in media and social media archives. This article introduces social psychologists to word embedding research via a consideration of bias analysis, a topic of central concern in the discipline. We explain how word embeddings are constructed and how they can be used to measure bias along bipolar dimensions that are comparable to semantic differential scales. We review recent studies that show how familiar social biases can be detected in embeddings and how these change over time and in conjunction with real-world discriminatory practices. The evidence suggests that embeddings yield valid and reliable estimates of bias and that they can identify subtle biases that may not be communicated explicitly. We argue that word embedding research can extend scholarship on prejudice and stereotyping, providing measures of the bias environment of human thought and action.

Biobased composites offer unique properties in the context of sustainable material production as well as end-of-life disposal, which places them as viable alternatives to fossil-fuel-based materials. However, the large-scale application of these materials in product design is hindered by their perceptual handicaps and understanding the mechanism of biobased composite perception, and its constituents could pave the way to creating commercially successful biobased composites. This study examines the role of bimodal (visual and tactile) sensory evaluation in the formation of biobased composite perception through the Semantic Differential method. It is observed that the biobased composites could be grouped into different clusters based on the dominance and interplay of various senses in perception forming. Attributes such as , , and are seen to correlate with each other positively and are influenced by both visual and tactile characteristics of the biobased composites. Attributes such as , , and are also positively correlated but dominated by visual stimuli. The perceptual relationships and components of beauty, naturality, and value and their constituent attributes are identified, along with the visual and tactile characteristics that influence these assessments. Material design leveraging these biobased composite characteristics could lead to the creation of sustainable materials that would be more attractive to designers and consumers.

Review
In recent years, with the rapid development of deep learning technology, great progress has been made in computer vision, image recognition, pattern recognition, and speech signal processing. However, due to the black-box nature of deep neural networks (DNNs), one cannot explain the parameters in the deep network and why it can perfectly perform the assigned tasks. The interpretability of neural networks has now become a research hotspot in the field of deep learning. It covers a wide range of topics in speech and text signal processing, image processing, differential equation solving, and other fields. There are subtle differences in the definition of interpretability in different fields. This paper divides interpretable neural network (INN) methods into the following two directions: model decomposition neural networks, and semantic INNs. The former mainly constructs an INN by converting the analytical model of a conventional method into different layers of neural networks and combining the interpretability of the conventional model-based method with the powerful learning capability of the neural network. This type of INNs is further classified into different subtypes depending on which type of models they are derived from, i.e., mathematical models, physical models, and other models. The second type is the interpretable network with visual semantic information for user understanding. Its basic idea is to use the visualization of the whole or partial network structure to assign semantic information to the network structure, which further includes convolutional layer output visualization, decision tree extraction, semantic graph, etc. This type of method mainly uses human visual logic to explain the structure of a black-box neural network. So it is a post-network-design method that tries to assign interpretability to a black-box network structure afterward, as opposed to the pre-network-design method of model-based INNs, which designs interpretable network structure beforehand. This paper reviews recent progress in these areas as well as various application scenarios of INNs and discusses existing problems and future development directions.

Review
Because changes to socioemotional cognition and behavior are an early and central symptom in many of the FTLD syndromes, an objective and standardized approach to patient identification and staging relies on availability of validated socioemotional measures. Such tests should reflect functioning in key selectively vulnerable brain networks central to socioemotional behavior, specifically the intrinsically connected networks underpinning salience (SN) and semantic appraisal (SAN). There have been many challenges to the development of appropriate tests for patients with the FTLD syndromes, including the difficulty of creating standardized evaluations for the highly idiosyncratic deficits caused by salience-driven attention impairments, the trade-off between behaviorally or psychophysiologically precise measures versus the need for easily administered measures that can scale to broader clinical contexts, and the complexities of measuring socioemotional behavior across linguistically and culturally diverse samples. A subset of available socioemotional tests are reviewed with respect to evidence for their ability to reflect structural and functional changes to the FTLD-specific SN and SAN networks, and their differential diagnostic utility in the neurodegenerative disease syndromes is discussed.

Prior studies of A:B::C:D verbal analogies have identified several factors that affect performance, including the semantic similarity between source and target domains (semantic distance), the semantic association between the C-term and incorrect answers (distracter salience), and the type of relations between word pairs. However, it is unclear how these stimulus properties affect performance when utilized together. To test their interactive effects, we created a verbal analogy stimulus set that factorially crossed these factors and presented participants with an analogical stem (A:B::C:?) with two response choices: an analogically correct (D) and incorrect distracter (D') term. The semantic distance between source and target word pairs was manipulated creating near (BOWL:DISH::SPOON:SILVERWARE) and far (WRENCH:TOOL::SAD:MOOD) analogies. The salience of an incorrect distracter (D') was manipulated using the sematic distance with the C-term creating low (DRAWER) and high (FORK) salience distracters. Causal, compositional, and categorical relations were presented across these conditions. Accuracies were higher for semantically near than far analogies and when distracter salience was low than high. Categorical relations yielded better performance than the causal and compositional relations. Moreover, a three-way interaction demonstrated that the effects of semantic distance and distracter salience had a greater impact on performance for compositional and causal relations than for the categorical ones. We theorize that causal and compositional analogies, given their less semantically constrained responses, require more inhibitory control than more constraining relations (e.g., categorical).

Social learning plays a prominent role in shaping individual preferences. The vicarious approach-avoidance effect consists of developing a preference for attitudinal objects that have been approached over objects that have been avoided by another person (model). In two experiments ( = 448 participants), we explored how the vicarious approach-avoidance effect is affected by agency (model's voluntary choice) and identification with the model. The results consistently revealed vicarious approach-avoidance effects in preference, as indicated by the semantic differential and the Implicit Association Test. Agency increased the size of the preference assessed through the semantic differential but did not significantly impact preference in the Implicit Association Test. Identification with the model had no significant impact on the vicarious approach-avoidance effect. Theoretical and practical implications of the results are discussed.

Meta-Analysis
BACKGROUND
Semantic and Phonological fluency (SF and PF) are routinely evaluated in patients with Alzheimer's disease (AD). There are disagreements in the literature regarding which fluency task is more affected while developing AD. Most studies focus on SF assessment, given its connection with the temporoparietal amnesic system. PF is less reported, it is related to working memory, which is also impaired in probable and diagnosed AD. Differentiating between performance on these tasks might be informative in early AD diagnosis, providing an accurate linguistic profile.
OBJECTIVE
Compare SF and PF performance in healthy volunteers, volunteers with probable AD, and patients with AD diagnosis, considering the heterogeneity of age, gender, and educational level variables.
METHODS
A total of 8 studies were included for meta-analysis, reaching a sample size of 1,270 individuals (568 patients diagnosed with AD, 340 with probable AD diagnosis, and 362 healthy volunteers).
RESULTS
The three groups consistently performed better on SF than PF. When progressing to a diagnosis of AD, we observed a significant difference in SF and PF performance across our 3 groups of interest (p = 0.04). The age variable explained a proportion of this difference in task performance across the groups, and as age increases, both tasks equally worsen.
CONCLUSION
The performance of SF and PF might play a differential role in early AD diagnosis. These tasks rely on partially different neural bases of language processing. They are thus worth exploring independently in diagnosing normal aging and its transition to pathological stages, including probable and diagnosed AD.
