AdAPT : Advertisement detector adaptation under newspaper domain shift with null-based pseudo-labeling
No full textDetecting advertisements in digitized newspapers is a key step in large-scale media analytics and digital archiving. However, variations in layout, typography, and advertisement design across publishers and time periods cause significant domain shifts that reduce the generalization ability of supervised detectors. This paper presents AdAPT, a confidence-guided pseudo-labeling pipeline for unsupervised domain adaptation in advertisement detection. The proposed method leverages both advertisement-free (Null) and advertisement-containing pages from unlabeled target domains to generate reliable pseudo-labels. By retraining a YOLO-based detector using labeled source data combined with filtered pseudo-labeled target samples, AdAPT achieves robust adaptation without requiring manual annotation. Experiments conducted on two unseen newspapers (Adresseavisen and iTromsø) demonstrate that Null-based pseudo-labeling provides the most stable and accurate adaptation, yielding up to 38% error reduction compared to the baseline. The results highlight AdAPT as a simple, scalable, and annotation-efficient solution for maintaining high-performance advertisement detection across diverse newspaper collections.CC BY 4.0Corresponding author: Faeze Zakaryapour SayyadReceived 16 October 2025, Revised 21 November 2025, Accepted 30 November 2025, Available online 1 December 2025, Version of Record 3 December 2025.Declaration of competing interestThe authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Faeze Zakaryapour Sayyad reports financial support was provided by Mid Sweden University.

A new resonant-based sensor for non-invasive measurement of blood glucose levels
Full text linkThis paper presents a rapidly developed non-invasive microstrip sensor for measuring blood glucose levels (BGLs). The sensor features a microstrip closed-loop square resonator integrated with an interdigital capacitor (IDC), creating a sensitive area for glucose detection when a patient’s finger is placed on it. Using odd and even mode analytical methods and transmission line theory, we analyzed the sensor’s performance. Results indicate that the second even mode demonstrates significant changes across a standard glucose concentration range. The sensor was designed and simulated in ANSYS high frequency structure simulator (HFSS), showing a resonance frequency shift of up to 24.9 MHz at 1.94 GHz and a sensitivity of 110 kHz per mg/dL over a detection range of 0 to 216 mg/dL. Additionally, the frequency shift exhibits a high linear correlation (0.9485). In summary, the proposed sensor shows significant promise for achieving precise measurements of BGLs

The Development of Self and Other Forgiveness from Adolescence to Emerging Adulthood
Full text linkThe purpose of this study was to investigate the development of self, others, and situation forgiveness from adolescence to emerging adulthood. To this end, 395 individuals, aged 12 to 25 years in four age groups living in Isfahan, Iran, were selected by cluster (for the first three groups) and available sampling (for the fourth group). The study was a cross-sectional study with using the causal-comparative design and the required data were collected with the Forgiveness Scale. The results of the analysis of variance showed that forgiveness of self had a slight decreasing trend from the beginning of adolescence to adulthood. The results also revealed that forgiveness of others declined from 12 to 16 years of age, however, it increased in emerging adulthood. Moreover, the changes in situation forgiveness were not significant in four groups. Eta squared results showed a small effect of age on the forgiveness of self (2%) and forgiveness of others (4%). Finally, there was no significant gender difference in the forgiveness of self and others in different age groups.Introduction*Forgiveness can be defined as a decision to release negative feelings, cognition, and behaviors based on a sense of sympathy, respect and grievance for guilty (Lavafpour et al., 2014). Neto et al. (2014) pointed out three forms of forgiveness: other, self, and situation forgiveness. Other forgiveness manifests itself in intentionally reducing the negative feelings and thoughts against others. Furthermore, self forgiveness refers to passionately releasing the sense of agony against oneself and conversely improving compassion and love for the self (Enright, 1996). Additionally, situation forgiveness refers to rendering all the negative thoughts and feelings surrounding the inevitable hard situations (Tompson et al., 2005). Chiaramello et al. (2008), in their study of the development of forgiveness in adolescence, found that teenagers in the middle of adolescence were less forgiving and more vindictive than in the beginning. Subkowiak et al. (1995) also found that teenagers usually forgave significantly less than adults in similar situations. After adolescence, forgiveness of others increases with age in adulthood. This is because adolescence is the time of identity formation (Berk, 2007, 2014) and emerging adulthood is the period of identity consolidation (Arnett, 2000; Lotfabadi, 2009). Moreover, different ways of socialization of boys and girls (Dastranj, 2013) may cause gender differences in their forgiveness. As such, it can be concluded that the desire to forgive has a developmental trend. This research study aimed to seek this developmental trend for forgiveness from adolescence to emerging adulthood. MethodThis study employed a cross-sectional study with a causal-comparative design. Its statistical sample included 395 individuals whose aged ranged from 12 to 25 years living in Esfahan, Iran. The group classification was a 12-year-old group (55 girls and 50 boys), a 14-year-old group (49 girls and 51 boys), a 16-year-old group (51 girls and 45 boys), and an 18-23-year-old group (48 girls and 46 boys). They were selected by cluster (for the first three groups) and available sampling (for the fourth group). The data were gathered using the Hartland Forgiveness Scale (2005). Hartland Forgiveness Scale (Thompson et al., 2005) includes 18 items in three subscales (self, other, and situation forgiveness). The items are on a 5-point Likert scale ranging from 1 (the least amount of forgiveness) to 5 (the highest amount of forgiveness). The descriptive indices (mean, standard deviation), independent group t-tests, multivariate analysis of variance, and Tukey's post hoc test were used to analyze the obtained data. ResultsAccording to the multivariate analysis of variance, there was a significant difference between age groups in the forgiveness of self and others. However, the eta squares for both variables were .02 and .04, respectively, which indicates a small effect. Self-forgiveness differed significantly only between the two groups of 12 and 18-25 years old. Self-forgiveness scores decreased among 18-25-year-olds as compared to 12-year-olds (mean diff.=1.31, p = 0.02). Nonetheless, there were significant differences between the three groups in terms of other forgiveness. There was a decrease in other forgiveness between 16-years-old group and to 12-years-old (Mean diff.=1.63, p = 0.05), and there was an increase in forgiveness for the 18-25 years-old and 14 and 16-years-old groups (Mean diff.= -1.686, p=0.05 and Mean diff.= -2.668, p=0.001). Independent t-tests were used to examine gender differences in forgiveness scores for girls and boys in each age group. Only for situation forgiveness among the12-years-old group, the gender difference was significant with an effect size of (η2=0.05, t=2.39, and p=0.01), while no difference was observed in the other groups. In the 12-year-old group, the scores of situation forgiveness were higher for boys than girls. ConclusionThe results showed that other forgiveness decreased during adolescence and reached its lowest level at the age of 16 and after that, in emerging adulthood, other forgiveness increased significantly. The research of Girard and Mallet (2012) and Chiramello et al. (2008) reported the developmental course of forgiveness of others in adolescents until the age of 15. Also, Subkowiak et al. (1995) stated that adolescents were significantly less forgiving than their same-sex parents in similar situations. As expected, the conflict of the emerging adulthood stage of intimacy versus isolation and relationships with others becomes important for the individual; therefore, the person preserves one’s valuable relationships by forgiving others' mistakes (Kaleta & Mróz, 2018). Also, the findings showed that the development of self-forgiveness has a downward slope, and the 18-25-years-old group forgave themselves significantly less than the 12-year-old group. During adolescence, when identity is formed, self-forgiveness does not change much, but with the emergence of self-esteem, self-evaluation takes place, and a person becomes more sensitive about one’s mistakes, and self-forgiveness becomes more difficult and decreases. However, this research study did not find significant changes in situation forgiveness in four groups. Unfortunately, research background focuses on the forgiveness of others, and other dimensions of forgiveness have not been carefully investigated yet. Therefore, there is little evidence to compare the findings of self-forgiveness and situation, especially during adolescence. In addition, some factors such as small effect sizes and low statistical power can limit generalization of the findings of the present study.

Analyzing Motifs and Poetic Imagery in Qasem Ali Ferasat’s Novels Headless Palms and Lady Golab
No full textAbstractThis article employs a descriptive-analytical approach to discern and analyze the poetic imagery present in two books, namely Headless Palms and Lady Golab, both written by Qasem Ali Ferasat. The investigations indicate that the literary arrays have a significant influence on the setting of both works. Headless Palms has abstract notions of anguish, suffering, aggression, resistance, sadness, and sacrifice, while Lady Golab has abstract components of depicting beauty, Musa and Golab's conditions, and the love they possess. Headless Palms is replete with anthropomorphisms that derive inspiration from a diverse range of symbols found in physical locations, occurrences, items, and virtual identities. Lady Golab combines symbols of personification that are abundant in lyrical notions. The headless palm trees acquire a sense of introspection through their representations of the sun, moon, water, and tree. Meanwhile, people revere Lady Golab, the female figure, as an embodiment of selflessness. The palm tree assumes a prominent role in the initial novel, serving as a symbol of defiance and self-sacrifice. Concurrently, the second novel delves into the concepts of love and acceptance. In Headless Palms, Ferasat draws emphasis to the Khorramshahr motif by employing personification and highlighting the heroic qualities of the fighters. Nevertheless, in Lady Golab, he adopts a contrasting method by employing poetic comparisons to entice the battle-worn warriors to return to a conventional existence.IntroductionAn essential form of literature that embodies resistance is known as the holy defensive novel. One of the valuable writing approaches employed in this type of fiction is the employment of diverse types of narrative to critically reassess reality. One of these techniques involves handling lyrical imagery. Imagery in every piece of writing encompasses several literary devices such as similes, metaphors, and irony; these elements contribute to the creation of poetic imagery. The utilization of simile and its related forms, such as metaphor and personification, in the novel can enhance the portrayal by effectively conveying the ambiance and emotional state of the characters.Examining fictitious visuals leads us to the fundamental elements of a piece of art. Alongside these visuals, there exists a topic or motif, as well as the shape and structure of the artwork, which together establish its prevailing concept or overall perspective. The motif is a prevailing conviction found in all literary works and contributes to the overall significance or central topic of the work. The meaning referred to in this context can encompass several elements such as a character, a picture, or a recurring linguistic pattern (Cuddon, 2006: 405). An effective method of analysis in literary criticism involves identifying themes and delineating their impact within the text.Motifs can be categorized into six groups: persons, events, objects, concepts, symbols, time, and place. These elements serve a specific purpose when they contribute to a story's movement, either through repetition, emphasis, or direct involvement (see Parsansab, 2018: 26). One of the motifs in the story is referred to as a "light motif." This motif contains the main theme and central point of the text. The term "leitmotif" in German refers to the repeated repetition of a specific verbal or musical phrase, set of definitions, or group of images (Abrams, 2017: 256). This research aims to analyze the significant issues in two books by Qasem Ali Ferasat by studying the poetic imagery employed.Literature ReviewWithin the realm of simile analysis in various novels, one can consult the article "The Function of Simile in Creating Space in the Novel Symphony of the Dead" by Asadi and Hosseini (2018). This article examines the aspects of similes, identifies their shared characteristics, and uncovers the underlying meanings and concepts conveyed in the text.The article "Analysis and Investigation of Motif Types and Their Functions in the Works of Balqis Soleimani" (2016) by Sarfi, Modbari, and Alinejad explores various types of motifs, including visual, linguistic, conscious, and unconscious motifs, and their roles in Soleimani's works. The article "Symbolic Motifs and Narrative Tricks in Ermia from the Series of Stories of the Holy Defense" (2009) by Fateme Kopa examines archetypes and symbolic motifs, including plants, water, voluntary dying, and the hero's change throughout the story.Within the scope of the two novels being examined, there are additional written works, such as "Comparison of Lifestyle in the Stories of Headless Palm Trees and Love in the Forbidden Area of Qasem Ali Ferasat" (2012) by Hanif. This article primarily explores the themes of venerating love, opposing tyranny, pursuing justice, and acknowledging sacrifice. The stories written by Qasem Ali Ferasat are significant. Zarifinia and Bashiri authored the "Analysis of the Lifestyle in the Novel Headless Palms and Deeply Rooted" (2021). Their conclusion is that in Headless Palms, the unity of the people in facing the adversary demonstrates the religious lifestyle as a consistent discourse.In Sadeghinia's (2017) article, "Investigation and Analysis of the Symbols of Stability and Their Relationship with the Elements of the Story in the Novel Lady Golab," the author scrutinizes the novel's prominent symbols, concluding that the most prevalent symbols represent people, thereby characterizing the novel as a character-driven one. Alipour's 2016 study, "A Constructivist Criticism on the Semantic Contrast of the Novel Lady Golab by Qasem Ali Ferasat," delves into the novel's character, location, description, and meaning contrasts. Currently, there is a lack of independent study that explores and compares poetic imagery in the novels Headless Palms and Lady Golab and identifies their significant features. The absence of such research is evident, and its importance is recognized.Research Methodology In this research, data analysis was conducted using a descriptive-analytical approach, following the collection of sources and note-taking. This study aims to analyze the similarities and differences between the two novels by examining poetic imagery and identifying various motifs such as characters, concepts, objects, events, time, and place.ConclusionOver the course of twelve years, Qasem Ali Ferasat authored two novels within the realm of sustainable fiction: Headless Palms (1983) and Lady Golab (1995). The initial novel explores the onset of the Baath regime's invasion, the occupation of Khorramshahr, and the martyrdom of soldiers. The subsequent novel delves into the challenges and dilemmas faced by veterans in the aftermath of the conflict. Both novels employ poetic imagery through similes, metaphors, and symbols. However, their motifs and leitmotifs exhibit notable distinctions, which have emerged due to the passage of time and society's gradual detachment from the ideals and passions of the war's early years.The novel Headless Palms explores the themes of suffering, the challenges of life, the atmosphere of an occupied city, invasion, resistance, warfare, and the compassion and intimacy between people. On the other hand, Lady Golab focuses on the description of the city of Tehran and its environment. The key components of its similes are the sanatorium, the depiction of the states of Musa and Golab, and the expression of love and warmth between them
The relationship between hypertensive disorders in pregnancy and endometriosis: a systematic review and meta-analysis
No full textAbstract Background Endometriosis is a chronic and debilitating disease that can affect the entire reproductive life course of women, with potential adverse effects on pregnancy. The aim of the present study is to investigate the association between hypertensive disorders in pregnancy and endometriosis. Method Relevant articles were searched from the Cochrane Library, PubMed, Scopus and Web of Science from inception up to December 2023. The full-text observational studies published in English that had a confirmed diagnosis of endometriosis were included. The case group included pregnant women diagnosed with endometriosis at any stage, while the control group consisted of pregnant women who had not been previously diagnosed with endometriosis. Two authors extracted and analyzed the data independently. Disagreements were reconciled by reviewing the full text by a third author. Endnote X9 was used for screening and data extraction. We used fixed and random effects models in Review Manager 5.3 to analyze the pooled data. The quality of the included studies was assessed using the Downs and Black checklist. Results Out of the 9863 articles reviewed, 23 were selected for meta-analysis. According to the results of this study, there was an association between endometriosis and gestational hypertension (OR = 1.11, 95% CI: 1.06, 1.16; I 2 = 45%, P < 0.00001; N = 8), pre-eclampsia (OR = 1.26, 95% CI: 1.18, 1.36; I 2 = 37%, P < 0.00001; N = 12), and hypertensive disorders in pregnancy (OR = 1.13, 95% CI: 1.06, 1.21; I 2 = 8%, P = 0.0001; N = 8). Conclusions This study confirmed that endometriosis may elevate the risk of developing gestational hypertensive disorders. Raising awareness of this issue will help to identify effective strategies for screening and early diagnosis of hypertensive disorders in pregnancy
Distributed medium access control for an enhanced physical-link layer interface
Full text link2020 Fall.Includes bibliographical references.Current wireless network architecture equips data link layer with binary transmission/idling options and gives the control of choosing other communication parameters to the physical layer. Such a network architecture is inefficient in distributed wireless networks where user coordination can be infeasible or expensive in terms of overhead. To address this issue, an enhancement to the physical-link layer interface is proposed. At the physical layer, the enhanced interface is supported by a distributed channel coding theory, which equips each physical layer user with an ensemble of channel codes. The coding theory allows each transmitter to choose an arbitrary code to encode its message without sharing such a decision with the receiver. The receiver, on the other hand, should decode the messages of interest or report collision depending on whether or not a predetermined reliability threshold can be met. Fundamental limits of the system is characterized asymptotically using a "distributed channel capacity'' when the codeword length can be taken to infinity, and non-asymptotically using an achievable performance bound when the codeword length is finite. The focus of this dissertation is to support the enhanced interface at the data link layer. We assume that each link layer user can be equipped with multiple transmission options each corresponds to a coding option at the physical layer. Each user maintains a transmission probability vector whose entries specify the probability at which the user chooses the corresponding transmission options to transmit its packets. We propose a distributed medium access control (MAC) algorithm for a time-slotted multiple access system with/without enhanced physical-link layer interface to adapt the transmission probability vector of each user to a desired equilibrium that maximizes a chosen network utility. The MAC algorithm is applicable to a general channel model and to a wide range of utility functions. The MAC algorithm falls into the stochastic approximation framework with guaranteed convergence under mild conditions. We developed design procedures to satisfy these conditions and to ensure that the system should converge to a unique equilibrium. Simulation results are provided to demonstrate fast and adaptive convergence behavior of the MAC algorithm as well as the near optimal performance of the designed equilibrium. We then extend the distributed MAC algorithm to support hierarchical primary-secondary user structure in a random multiple access system. The hierarchical user structure is established in the following senses. First, when the number of primary users is small, channel availability is kept above a pre-determined threshold regardless of the number of secondary users that are competing for the channel. Second, when the number of primary users is large, transmission probabilities of the secondary users are automatically driven down to zero. Such a hierarchical structure is achieved without the knowledge of the numbers of primary and secondary users and without direct information exchange among the users. Furthermore, we also investigate distributed MAC for a multiple access system with multiple non-interfering channels. We assume that users are homogeneous but the multiple channels can be heterogeneous. In this case, forcing all users to converge to a homogeneous transmission scheme becomes suboptimal. We extend the distributed MAC algorithm to adaptively assign each user to only one channel and to ensure a balanced load across different channels. While theoretical analysis of the extended MAC algorithm is still incomplete, simulation results show that the algorithm can help users to converge to a near optimal channel assignment solution that maximizes a given network utility
Can acute mobilization and oscillation training profit on the joint position sense and strength of the rotator cuff muscles in young tennis players?
No full textThe rotator cuff is a group of muscles and tendons that act to stabilize the human shoulder and allow for its extensive range of motion. This study aimed to compare the immediate effect and durability of mobilization and oscillation dumbbell (OD) training on the Joint Position Sense (JPS) and strength of rotator cuff muscles in young tennis players. Twenty-six tennis players were divided into two experimental groups. G1 only performed mobilization techniques while G2 only performed OD training, before, after and after one week of the protocols, the strength and JPS of the shoulder joint were measured with an isokinetic dynamometer. Repeated analysis of variance (RMANOVA) and Bonferroni post hoc test were used to examine the differences between the groups. The analysis of covariance was used to examine the differences between the groups. In general, the results showed a significant effect of both mobilization techniques and OD training programs on the JPS and internal and external rotation strength of young tennis players, but only one difference was observed between the two in external rotation for the eccentric/concentric action at 120°/sec (p=0009; ƞ2p= 0.32). Moreover, the main findings showed that mobilization techniques and OD improved internal and external rotations after the protocol and after one week when compared with baseline for the concentric/concentric and eccentric/concentric at 60°/sec and 120°/sec (p 0.05). Based on this, it seems that in healthy tennis players, both one-session mobilization techniques and OD training can be used to improve JPS and strength. [ABSTRACT FROM AUTHOR
