Iguanodon: A Code-Breaking Game for Improving Visualization Construction Literacy
Authors: Adelberger Patrick , Lesota Oleg , Eckelt Klaus , Schedl Markus , Streit Marc
Published: August 2023

In today's data-rich environment, visualization literacy—the ability to understand and communicate information through charts—is increasingly important. However, constructing effective charts can be challenging due to the numerous design choices involved. Off-the-shelf systems and libraries produce charts with carefully selected defaults that users may not be aware of, making it hard to increase their visualization literacy with those systems. In addition, traditional ways of improving visualization literacy, such as textbooks and tutorials, can be burdensome as they require sifting through a plethora of resources.To address this challenge, we designed Iguanodon, an easy-to-use game application that complements the traditional methods of improving visualization construction literacy. In our game application, users interactively choose whether to applydesign choices, which we assign to sub-tasks that must be optimized to create an effective chart. The application offers multiple game variations to help users learn how different design choices should be applied to construct effective charts. Furthermore, our approach easily adapts to different visualization design guidelines. We describe the application's design and present the results of a user study with 37 participants. Our findings indicate that our game-based approach supports users in improving their visualization literacy.
Forecasting phase-field variable in brittle fracture problems by autoregressive integrated moving average technique
Authors: Nguyen Cuong
Published: August 2023

Phase-field modeling is a powerful and versatile computational approach for modeling the evolution of cracks in solids. However, phase-field modeling requires high computational cost for capturing accurately how cracks develop under increasing loads. In brittle fracture mechanics, the crack initiation and propagation can be considered as a time series forecasting problem so they can be studied by observing the change of the phase-field variable, which represents the level of material damaging. In this paper, we develop a rather simple approach utilizing autoregressive integrated moving average technique (ARIMA) to predict the variation of the phase-field variable in an isothermal, linear elastic and isotropic phase-field model for brittle materials. Time series data of the phase-field variable is extracted from numerical results using coarse finite-element meshes. Two ARIMA schemes are introduced to exploit the structure of the collected data and provide a prediction for the change of phase-field variable when using a finer mesh, that gives a better results in terms of accuracy but it requires highly computational cost.
A critical appraisal of the Dual Process account of moral judgment
Authors: Quinlan Philip , Cohen Dale
Published: August 2023

The Dual Process account asserts that moral judgments are the result of a competition between two independent decision processes: a utilitarian process and a deontological/affective process. We trace the development of the dual process account and highlight how the neural and behavioral evidence almost universally relies on the validity of a series of untested statements that, collectively, we call the Dual Process assumption. We show how the acceptance of this assumption produces experimental methods that cannot falsify the dual process account. By way of contrast, we highlight a competing account of moral reasoning, Psychological Value Theory (PVT), which is embodied in a computational model that supports very detailed and falsifiable predictions. PVT is based on a radically different set of assumptions to those of the dual process account. Such assumptions accord well with generally accepted processes of stochastic decision-making. PVT’s predictions have been verified and provide strong evidence that the Dual Process assumption is invalid. We recommend reassessing the conclusions of research that relies on the Dual Process assumption.
No support for a causal role of primary motor cortex in construing meaning from language: An rTMS study
Authors: Solana Pablo , Escámez Omar David Escámez , Casasanto Daniel , Chica Ana B. , Santiago Julio
Published: August 2023

Embodied cognition theories predict a functional involvement of sensorimotor processes in language understanding. In a preregistered experiment, we tested this idea by investigating whether interfering with primary motor cortex (M1) activation can change how people construe meaning from action language. Participants were presented with sentences describing actions (e.g., "turning off the light”) and asked to choose between two interpretations of their meaning, one more concrete (e.g., "flipping a switch") and another more abstract (e.g., "going to sleep"). Prior to this task, participants’ M1 was disrupted using repetitive transcranial magnetic stimulation (rTMS). The results yielded strong evidence against the idea that M1-rTMS affects meaning construction (BF01 > 30). Additional analyses and control experiments suggest that the absence of effect cannot be accounted for by failure to inhibit M1, lack of construct validity of the task, or lack of power to detect a small effect. In sum, these results do not support a causal role for primary motor cortex in building meaning from action language.
Psychological Mediators of Reduced Distress: Preregistered Analyses from a Randomized Controlled Trial of a Smartphone-Based Well-Being Training
Authors: Hirshberg Matthew James , Dahl Cortland , Bolt Daniel M. , Davidson Richard , Goldberg Simon
Published: August 2023

Understanding why interventions work is essential to optimizing them. Although mechanistic theories of meditation-based interventions (MBIs) exist, empirical evidence is limited. We randomly assigned 662 adults (79.9% reported clinical levels of anxiety or depressive symptoms) to a four-week smartphone-based MBI or wait-list control condition early in the COVID-19 pandemic. Psychological distress and four theory drive preregistered psychological mediators of well-being (mindful action, loneliness, cognitive defusion and purpose) were assessed five times during the intervention period and at three-month follow-up. Using preregistered latent growth structural equation mediation models, assignment to the intervention predicted significant gains on all mediators which in turn significantly mediated follow-up distress (22.2%–64.5% of intervention effect on distress). No significant mediation pathway was observed in an exploratory multiple mediator analysis, but reduced loneliness accounted for 70.0% of the combined indirect effect. Multiple psychological pathways may mediate reduced distress in a digital MBI.
Feedback Orientation: A Meta-Analysis
Authors: Katz Ian M. , Jordan Caroline Mackenzie , Rudolph Cort
Published: August 2023

Feedback orientation reflects an individual difference in one’s receptivity to feedback. We present the results of a meta-analysis of the feedback orientation literature. Based on k = 46 independent samples, representing n = 12,478 workers, meta-analytic results suggest that feedback orientation is positively related to learning goal orientation (rc = 0.39), job satisfaction (rc = 0.33), work performance (rc = 0.35), and feedback seeking (rc = 0.43). Meta-analyticregression and dominance analysis was used to tease apart how related informal feedback constructs (i.e., feedback seeking, feedback environment, & feedback orientation) aid in the prediction of outcomes, above and beyond two established predictors of job attitudes and work performance: role clarity and leader-member exchange. We also present an interactive exploratory data analysis tool to aid in developing future research questions regarding theconnection between informal feedback constructs and work outcomes. To illustrate the use of this tool, we present the results of an exploratory, theory-based test of the linkage between feedback orientation, feedback seeking, and job satisfaction. The results of this meta-analysis help illustrate how employees experience informal feedback at work, and how feedback orientation may be theoretically differentiated from related informal feedback constructs.
A simulation-based test to investigate interrater agreement for binary time series
Authors: Bodner Nadja
Published: August 2023

In observational studies, intensive longitudinal data are often collected by coding the presence/absence of behavior across time. Having a sufficiently high interrater agreement is then quintessential. Although a host of alternatives exist, Cohen’s Kappa has been most popular ever since the measure has been introduced. In many cases, the obtained interrater agreement values are interpreted using the benchmarks provided by, for example, Landis and Koch. This is, however, problematic because of two reasons: First, the value of Cohen’s Kappa (and many other interrater agreement measures) is impacted by the prevalence of the coded behavior. Second, these measures ignore the serial dependence that typically characterizes time series data. In this study, we aim to develop a test that allows interpreting a Kappa value in a given situation. Therefore, we will make use of the error rate committed by the coders during that coding process. For good coding reliability, we will, of course, aim for data where only a few mistakes have been committed. We will introduce a simulation paradigm that accounts for the serial dependence and relative frequency of the true data but also implements several mistakes corresponding with the benchmarks of Landis & Koch. On this data, we calculate Cohen’s Kappa. This sampling distribution which contains a fixed number of mistakes is used for a one-sided significance test that investigates whether the values calculated on the rater-reported data are significantly higher than could be expected given the implemented error rate (and therefore are of acceptable quality).
High Ventilation Breathwork practices: An overview of their effects, mechanisms, and considerations for clinical applications
Authors: Fincham Guy W. , Kartar Amy , Uthaug Malin , Anderson Brittany , Hall Lottie , Nagai Yoko , Critchley HUgo , Colasanti Alessandro
Published: August 2023

High Ventilation Breathwork (HVB) refers to practices employing specific volitional manipulation of breathing, with a long history of use to relieve various forms of psychological distress. This paper seeks to offer a consolidative insight into potential clinical application of HVB as a treatment of psychiatric disorders. We thus review the characteristic phenomenological and neurophysiological effects of these practices to inform their mechanism of therapeutic action, safety profiles and future clinical applications. Clinical observations and data from neurophysiological studies indicate that HVB is associated with extraordinary changes in subjective experience, as well as with profound effects on central and autonomic nervous systems functions through modulation of neurometabolic parameters and interoceptive sensory systems. This growing evidence base may guide how the phenomenological effects of HVB can be understood, and potentially harnessed in the context of such volitional perturbation of psychophysiological state. Reports of putative beneficial effects for trauma-related, affective, and somatic disorders invite further research to obtain detailed mechanistic knowledge, and rigorous clinical testing of these potential therapeutic uses.
A Proposed Framework for Human-like Language Processing of ChatGPT in Academic Writing
Authors: Mahyoob Mohammad , Algaraady Jeehaan , Alblwi Abdulaziz
Published: August 2023

The study proposed a framework for analyzing and measuring the ChatGPT capabilities as a generic language model. This study aims to examine the capabilities of the emerging technological Artificial Intelligence tool (ChatGPT) in generating effective academic writing. The proposed framework consists of six principles (Relatedness, Adequacy, Limitation, Authenticity, Cognition, and Redundancy) related to Artificial Language Processing which would explore the accuracy and proficiency of this algorithm-generated writing. The researchers used ChatGPT to obtain some academic texts and paragraphs in different genres as responses to some textbased academic queries. A critical analysis of the content of these academic texts was conducted based on the proposed framework principles. The results show that despite ChatGPT’s exceptional capabilities, its serious defects are evident, as many issues in academic writing are raised. The major issues include information repetition, nonfactual inferences, illogical reasoning, fake references, hallucination, and lack of pragmatic interpretation. The proposed framework would be a valuable guideline for researchers and practitioners interested in analyzing and evaluating recently emerging machine languages of AI language models.
The New Economics of Industrial Policy
Authors: Juhász Réka , Lane Nathaniel , Rodrik Dani
Published: August 2023

We discuss the considerable literature that has developed in recent years providing rigorous evidence on how industrial policies work. This literature is a significant improvement over the earlier generation of empirical work, which was largely correlational and marred by interpretational problems. On the whole, the recent crop of papers offers a more positive take on industrial policy. We review the standard rationales and critiques of industrial policy and provide a broad overview of new empirical approaches to measurement. We discuss how the recent literature, paying close attention to measurement, causal inference, and economic structure, is offering a nuanced and contextual understanding of the effects of industrial policy. We re-evaluate the East Asian experience with industrial policy in light of recent results. Finally, we conclude by reviewing how industrial policy is being reshaped by a new understanding of governance, a richer set of policy instruments beyond subsidies, and the reality of de-industrialization.

A Study of Dance Usage in Kusa Paba Movie
Authors: K. G. J. U. Dissanayake , A. K. M. Manamperi
Published: August 2023

A dance technique used to supplement the acting can be identified in modern Sinhala films that have taken Indian historical stories as a source. The Sinhala film Kusa Paba, directed by Sunil Ariyaratne, is based on the Kusa Jãtaka in the book Pansiya Panas Jathaka Potha, and it is set in North Indian social culture. The research problem of this study is to investigate how the proposed social culture is revealed through the use of dance in the Kusa Paba film. The central assumption of this study is to identify the use of dance in this film and, secondarily, to recognize the proposed social culture. This study is based primarily on qualitative data and inductive reasoning. The data gathered through the methods of watching the film, library research, and interviews has been presented as a contextual analysis. For those dance scenes, costumes and composition, background decoration, and music styles were well used to represent North Indian culture. The study revealed that South Indian culture is highlighted through the use of dances such as Kudirai Attam, Kathakali and the constant use of basic postures, foot movements and hasta mudras in Bharata Nãtyam. The study concluded that other dance-related features are more indicative of the projected social culture than the dance style and motions employed in the Kusa Paba movie. Accordingly, the research recommends that these negative impacts can be reduced through proper source analysis and through an optimal interrelationship with the film squad to choreograph the cinema dance.

The Humanities and Social Sciences (HSS) involve understanding the human experience and the relationships between individuals and groups in society. The adoption of digital technologies has challenged the discipline of HSS, creating an entirely new environment for the study of human activities. This research aims to explore the employment of digital tools, resources and services in HSS research. Further, the use of digital methods (DM) throughout the research process; the impact of COVID-19 on the use of DM in research; the constraints of using DM in research were tested. Both quantitative and qualitative data were collected from Colombo, Kelaniya and Sri Jayewardenepura universities targeting academics in Economics, English, English Language Teaching, Geography, History and Archeology, Buddhist Studies, Political Science, Sinhala, and Sociology. Considering the digital infrastructure facilities, most of the academics rated email (45.6%) and LMS services (46.7%) as excellent but maintenance provided by the institute was not adequate. Most academics rated good on access to data storage (37.9%); reference management software (27.5%); plagiarism detection software (29.1%); institutional repository (35.2%); and support to online publications (39.6%) provided by their institutes. 55.7% of surveyed academics in SS often use digital data collection methods while in the Humanities it was 43.4%. Online publishing was most often used by SS (50.9%) and only 39.5% by the Humanities. 53.8% of SS academics and 43.4% of humanities academics often use cloud storage. Findings confirmed the expansion of using digital research methods during the pandemic compared to the early pandemic situation. Collaborative research works, virtual conferences, citation databases and digital indexing were identified as popular trends.
Merger Reform: Canada’s Telecommunications Industry and the Public Interest
Authors: Hudes Kevin
Published: August 2023

Background: Merger control is an increasingly necessary and important policy mechanism, particularly in the telecommunications sector. Given that a Rogers–Shaw merger could still occur, this article explores and evaluates various approaches to merger review and control.

Analysis: By comparing the Competition Bureau’s approach to merger control in Canada with merger control strategies employed by competition authorities in Europe, this article reveals limitations in Canada’s merger control process and the Competition Act.

Conclusions and implications: The Competition Bureau’s treatment of structural merger control remedies in conjunction with legislation that prioritizes economic efficiencies over the needs of consumers, and a lack of public interest considerations, drastically limits the scope of the Competition Bureau’s capacity to regulate the telecommunications industry appropriately. This article provides recommendations that would better equip competition regulators in Canada.
Alternative Makings in American Poetry
Authors: Hart Jonathan Locke
Published: August 2023

There are many ways to look at the making of American poetry. The author begins with the land and Native Americans in the New World, including what is in the United States, decentring or defamiliarizing the Anglo-American tradition by beginning with the Indigenous peoples and their languages and discussing poets of aboriginal, African, and Asian backgrounds in poetry and translation. With settlers, the author begins with Gaspar Pérez de Villagrá, a Creole writing an epic in Spanish, and ends with Forrest Gander, also born in the United States, including a poem that mixes English and Spanish. In between, a mixed group of poets is discussed to show the richness and diversity of American poetry and culture: Anne Bradstreet, Phillis Wheatley, Langston Hughes, Joan Kane, Marilyn Chin, Russell Leong, and the translation of Shuri Kido by Gander and Tomoyuki Endo. These are some alternative makings of American poetry in one strand among many, then, now, and going forward.
MATHEMATICAL MODEL OF WINTER WHEAT PRODUCTIVITY IN THE RAINFED CONDITIONS OF THE SOUTH OF UKRAINE DEPENDING ON THE CROP’S VARIETAL TRAITS
Authors:   Institute of Climate-Smart Agriculture of NAAS, Lykhovyd P.
Published: August 2023

Abstract The paper is devoted to elucidation of the results of mathematical modeling of winter wheat yields, cultivated in the rain fed conditions of the South of Ukraine, depending on the varietal traits of the crop. The purpose of the study is the development of the mathematical equation of winter wheat varieties yields in the rain fed conditions of the steppe zone depending on such varietal traits of the crop as winter resistance, resistance to lodging, shedding, and drought. Methods.The methodology of multiple regression analysis was applied to conduct the research and develop the mathematical model of winter wheat ideotype. Experimental basis for mathematical modeling was represented by the results of ecological varietal testing, conducted in the rain fed conditions at the fields of PC «Zoria» and SE «Illich-Agro Zaporizhzhia». Evaluation of the model’s fitting quality and prediction accuracy was performed by the values of the multiple determination coefficient and mean absolute percentage error. To understand the influence of the studied traits on winter wheat productivity, rank correlations were calculated, and to establish the relationship and affinity between the varietal traits a matrix of Fechner’s correlation coefficients was computed. Mathematical computations were performed within Microsoft Excel 365 spreadsheets processor and BioStat v.7 statistical toolkit. Results. Mathematical evaluation of the studied varietal traits of winter wheat allowed to establish that the highest positive value in the crop’s yield formation in the rainfed conditions of the steppe zone of Ukraine is attributed to drought tolerance (Pearson’s pairwise correlation coefficient is +0.19), while other factors play a secondary role or have negative effect on the crop’s productivity. Evaluation of the multiple regression model confirms the above results and additionally significant positive effect of shedding resistance. The multiple regression model has high adequacy (multiple correlation coefficient is 0.9791; determination coefficient is 0.9587; adjusted determination coefficient is 0.8463) and prediction accuracy (mean absolute percentage error is 18.45%). Conclusions. According to the results of multiple regression analysis and rank correlation calculations, the strongest effect on the crop’s productivity in the mentioned agro-productive conditions is provided by such a varietal trait as drought tolerance, while the minimum effect has cold (winter) resistance. The proposed mathematical model of winter wheat productivity in the rainfed conditions of the South of Ukraine has high fitting quality and moderately high prognostic value. Key words: winter resistance, ideotype of a variety, mathematical model, drought resistance, regression analysis, resistance to lodging, shedding resistance, yielding capacity.

Published: August 2023

The paper is dedicated to examination of atmospheric air pollution in Ukraine that is aimed at establishing basic air quality conditions prior to the full-scale Russian invasion. Analyses cover five air pollutants (dust, sulfur dioxide (SO2), carbon monoxide (CO), nitrogen dioxide (NO2), and formaldehyde (CH2O)) across 126 monitoring stations in 39 cities. It was found that the most dangerous excess of air pollution levels in cities was associated with dust, NO2, and CO. At the same time, SO2 content usually did not reach dangerous levels. The highest frequency of exceeding the threshold one-time levels was common for the cities with well-developed industrial facilities. Dangerous air pollution was observed in 15–60% of cases, depending on a pollutant. Dust and NO2 concentrations of the most polluted cities were 10 times higher than their concentrations in smaller cities having no significant industrial emissions. The difference in average CO, SO2, and CH2O concentrations among monitoring stations constituted 3-5 times. We studied the patterns of pollutants' seasonal variability recorded at the monitoring stations. Normally, no significant seasonality except for CH2O and dust was observed. The interannual variability of pollutants, emissions, and their trends were analyzed for the period since 2008. We identified a certain discrepancy in trends between pollutants’ concentrations and emission data over the last years. Pollutant content often continued to grow concurrently with emission reductions. The impact of atmospheric phenomena and wind parameters was studied mainly in terms of its role in formation of high and low atmospheric pollution levels. The analysis indicated a crucial role of local conditions in the formation of an atmospheric pollution field next to monitoring stations. Varying atmospheric pollution values across different monitoring stations within a specific city can be different even under the influence of the same atmospheric phenomena. The wind impact also formed different patterns of atmospheric pollution within same city. 12% to 22% of all monitoring stations (depending on a pollutant) indicated a prevailing impact of a single emission source (or a combined impact of a group of sources). At the same time, air pollution at other monitoring stations was highly variable, with elevated pollution levels being transported from numerous directions. The analysis of the air pollution-affected condition presented in the paper could be used as a basis for comparing ground-level pollution and assessing the warfare consequences in Ukraine. The research emphasizes the importance of updating the information about ground-based monitoring stations.
Comprehensive assessment of anthropogenic loads and consequences of their influence on the environmental state of water bodies (as exemplified by the Gruzka River, Kirovohrad Region)

Published: August 2023

The relevance of the research is determined by the need of developing and improving the methods for assessing the extent and consequences of anthropogenic loads' impact on water bodies.

The research was carried out as part of the study and research activities conducted by the Department of Hydroecology and Water Research of OSENU. It is dedicated to the topic "Assessment of Anthropogenic Impact on Aquatic Ecosystems".

The purpose of the work is to determine the environmental status of water bodies based on the comprehensive approach (calculations related to the consequences of anthropogenic loads' impact on water resources and the environmental state of surface waters, including assessment of pollution risks and failure to achieve environmental objectives).

Research methods include assessment of the characteristics of unstudied rivers' water resources in terms of hydrology based on the used meteorological data (climate-runoff model); assessment of anthropogenic loads' impact on water resources and on prospects of achieving a good environmental state of water bodies in accordance with the requirements of the EU's WFD; assessment of environmental risks based on the Prob function application and creation of a scale of water quality indicators and risks correspondence.

Determination of a comprehensive indicator of the Gruzka River's water resources use showed that reduction of water flow characteristics due to climate changes does not significantly affect the river's environmental condition that remains "unsatisfactory".

It was also established that household wastewater is the main pollutant of the Gruzka River that supplies water to reserve water reservoir Lelekivske (City of Kropyvnytskyi, Kirovohrad Region). Almost all criteria related to assessment of the consequences of anthropogenic loads (wastewater discharge, plant and animal husbandry, chemical and physico-chemical parameters) indicate a risk of not achieving a good ecological state. During the modern period, the river continues suffering from significant anthropogenic influence whose level is close to the limit of ecosystem sustainability.

It was established that the use of ER environmental risk that is based on the Prob indicator complements the information about the river's environmental state.

The proposed comprehensive approach can be used for water bodies that remain unsufficiently studied in terms of hydrology and hydrochemistry.
Spin Catalysis in Photochemical Reactions and Its Applications to Quantum Information Nanotechnology

Published: August 2023

Chemistry as a science about spin and electric charge of micro particles which provide driving forces of atomic interactions and molecular structure transformations fits pretty well to the modern Quantum Information Science (QIS) requirements. Today’s computers operate only electric current signals in the semiconductor networks but the electron-spin properties are not exploited in a large extend. Spintronics provides spin-polarized currents and manipulates magnetic spin interactions; it uses mostly solid state chemistry of heavy elements. But a rich organic chemistry of solvents and fin films offers a great potential for molecular electronics and quantum computing. Photo-excited organic complexes of the “chromophore–radical” type provide good promise for many technological applications in molecular spintronics and electronics, including QIS technology. The doublet state photo excitation of stable organic radical being delocalized onto the linked anthracene molecule within picoseconds and subsequently evolved into a quartet state for big radicals (a pure high spin state) of the mixed radical-triplet character presents a sensible spin-optical interface for qubit in quantum computing. This high-spin state is coherently addressable with EPR microwaves even at room temperature, with the optical read-out induced by intersystem crossing (ISC) to emissive triplet state. Such integration of radical luminescence and high-spin states EPR provides the organic materials involvement into emerging QIS technologies

Published: August 2023

To study the process of interaction between the working bodies of soil tillage machines and the soil, it is necessary to create a physical and mathematical model of the environment that reflects the physical and mechanical properties of the real soil as accurately as possible. The existing analytical models are used separately from each other, which leads only to a one-sided consideration of the scientific and technical problem. Today, it is quite difficult for agricultural engineers to investigate the process of interaction of tillage working bodies with the soil during the design of new structures due to the lack of simple analytical physical and mathematical models. In order to simplify these calculations within the framework of agricultural machinery engineering, it is necessary to use software that will combine the achievements of agricultural mechanics. The goal is to simulate and study the process of interaction of tillage working bodies with the soil using Simcenter STAR-CCM+. In the course of the study, the interaction process of the most common tillage working bodies, such as a cultivator’s arrow foot, a disc harrow on an elastic rack, a deep loosener (chisel plow), a flail plow and a smooth roller, was simulated using volume of fluid (VOF) and discrete element methods. (DEM). The application of the VOF method allows to determine the non-primary flow of the soil relative to the working body, and the DEM method allows to determine the distribution of velocities and interaction forces of soil particles. With the help of Simcenter STAR-CCM+, it is possible to visualize the interaction process and determine the height of the ridges formed and the depth of the furrows and their location in space

Background: Human Papilloma virus (HPV) is the main cause of cervical cancer. Infection with HPV can be reflected by overexpression of p16ink4a. Aim of the study: we aimed at evaluating the expression of p16ink4a in cervical cancer patients and its prognostic significance. Patients and methods: This retrospective registry and follow up study was conducted on 95 women diagnosed with cervical cancer. After screening of patients presented to our hospitals; 50 patients were eligible for inclusion in the study. P16ink4a was assessed by immunohistochemistry on archived tumor’s samples and correlation with different epidemiological, clinical and pathological data was performed. Prognostic impact of P16ink4a on overall survival (OS) and event free survival (EFS) was evaluated.Results: Median age of patients was 55 years. The main presenting symptom was bleeding. Most of the patients presented with late FIGO staging 64% with stage IIIb and 10% with stage IIb. P16ink4a was positive in 80% of patients. Correlation between P16ink4a and different clinic-epidemiological data revealed positive significant correlation with tumor grade and tumor size (P values of 0.03 and 0.05 respectively). Considering the effect of p16ink4a expression and EFS and OS, our study failed to show any significant correlation.Conclusion: The late stage at presentation of our population encourages the need for national screening program. The main cause of cervical cancer is HPV reflected by positive P16 similar to international literature. In our study the failure to reach a significant correlation with survival may be due the small sample size.

Background: Distinguishing between pleural epithelioid mesothelioma, lung adenocarcinoma, and poorly differentiated squamous cell carcinoma (SCC) is a challenge in some cases. A panel of markers has been recommended by the International Mesothelioma Interest Group (IMIG) guideline to differentiate epithelioid mesothelioma from lung adenocarcinoma and SCC. However, the use of novel highly specific immunohistochemical (IHC) markers is still required. Objectives: This study aimed to evaluate glypican-1 (GPC1) expression in epithelioid mesothelioma, lung adenocarcinoma, and SCC, correlating its expression with some known clinicopathological parameters to clarify its diagnostic and prognostic value.Methods: This study included seventy specimens designated as 20 cases of pleural epithelioid mesothelioma, 30 cases of lung adenocarcinoma, and 20 cases of lung SCC. GPC1 expression was evaluated using immunohistochemistry (IHC). The data was analyzed statistically by SPSS software 25. GPC1 expression was correlated to different clinicopathologic data using Chi-square test. The study was conducted according to local Ethical Committee regulations. Results: This study detected positive GPC1 reactivity in all cases (100%) of pleural mesothelioma and lung SCC, in which increased GPC1 expression was correlated to large-sized, high grade, advanced stage tumors, and the presence of lymph node metastasis (LNM). In contrast, GPC1 expression was absent in about 93% of lung adenocarcinoma cases, and only 2 cases exhibited weak focal expression. Conclusion: Our findings demonstrated that GPC1 expression is upregulated in advanced pleural mesothelioma and pulmonary SCC; tumors with high GPC1 expression exhibited more advanced biological behavior.

Objective: To study and correlate PDL-1 expression with Tumour budding and Tumour Infiltrating Lymphocytes in Colorectal Carcinoma. Background: Colorectal cancer (CRC) is third most common cancer with a high mortality. Many attempts have been made to raise overall survival of CRC patients. The immune system plays an important role in clearing the unhealthy cancer cells. Programmed death 1 (PD1) is a regulatory molecule which dampens the immune response when bound to one of its complementary ligands (PDL1). Its expression is related to the response of immunotherapy in CRC treatment which has been exploited in recent times. However, its prognostic value is still controversial, and the distribution of PD-L1 on tumour Cells or Immune Cells has not been comprehensively analysed. Method: A total of 30 patients diagnosed with CRCs were included who underwent surgical intervention. Cases who took preoperative neoadjuvant chemotherapy or radiotherapy were excluded. IHC analyses of PDL1 was done and was correlated with tumour budding and Tumour Infiltrating Lymphocytes (TILs) and statistical significance was assessed. Results: 11 cases showed low bud count at the invasive front out of which only 3 cases showed PDL1 positivity. The rest 19 cases had high bud count out of which 18 were PDL 1 positive. This difference was highly significant (p = 0.002). In Low Bud / High TILs, 75% cases showed no PDL1 expression in tumour cells, whereas 62.5% cases showed PDL1 positivity in TILs whereas in High Bud / Low TILs group, all the cases (100%) showed PDL1 expression in tumour cells whereas only 75% cases showed PDL1 positivity in TILs, again being statistically significant (p <0.001). Conclusion: This study showed an inverse correlation between PDL1 in tumour buds and immune cells, thus emphasising the role of tumour microenvironment. Our study reiterates the fact that high expression of PDL1 in tumour cells suppresses antitumor response whereas its high expression in TILS correlates with a better prognosis.

Objective: Multifocality in gynecologic malignancies is a common phenomenon, however synchronous tumors may occur. Synchronous cancers are about 1.7% of gynecologic malignancies. Methods: A 57-year old female with chief complaint of vaginal bleeding was admitted. Endometrial curettage and cervical biopsy was done.Result: Pathologist reported: compatible with papillary adenocarcinoma, Grade II in endometrial sample and squamous epithelium with moderate dysplasia and tiny fragments of atypical glandular epithelium in endocervical samples. The patient refused for surgical excision of the lesion and insisted on to treat with conventional herbal medicine. Later Pap smear was done and pathologist reported: “High grade squamous intraepithelial lesion (HSIL) and atypical glandular cells, favor neoplastic in atrophic background”. Conclusion: In the case of gynecologic cancer be careful that it may accompany another gynecologic malignancy or premalignant lesion. The second lesion may occur synchronous or metachronous or may be metastatic. Many of the synchronous malignancies are presented in lower stages and have better prognosis than metastatic lesion. Thorough sampling and examination is important in correct diagnosis and treatment.
