Published: August 2023

Details and elements of structures, which are made of functionally heterogeneous materials and have the property of shape memory and behave pseudo-elastically, may be under the influence of complex loads in the process of manufacturing and operation. Uneven heating of bodies in combination with force factors can lead to large deformations of the material and complex deformation processes. The existing models of the behavior of such elements do not take into account the nonlinearity of geometric relationships and are unsuitable for use with large deformations.
The article deals with the bending of a plate of finite dimensions from a functionally heterogeneous material in the presence of large plastic deformations. The simulation of plate behavior is based on a nonlinear phenomenological model that describes the properties of shape memory alloys and the thermos-pseudo-plastic behavior of the material at a point. A diagram of a pseudo-elastic material consisting of three curved sections is used.
The first feature of the formulation of the problem of specifying the area of geometric nonlinearity is the formulation of the boundary conditions around the support. If for a linear problem they are set only along the support line, then to refine the geometrically nonlinear solution, the zero vertical displacements of the plate points and, accordingly, the speed of movement were set in the vicinity of the area of contact with the support. The second feature of the refinement is a significant reduction in the number of coordinate integration steps (up to 5%). At the same time, in order to fulfill the condition of stability, a proportional reduction of the integration step over time is necessary. For a reliable comparison of results, it is necessary to increase the number of time integration steps while decreasing the integration steps by coordinates. This problem was solved using a sequence of numerical experiments. The third feature consists in solving the additional problem of interpolation of the required values in the nodes of the new finer grid by the corresponding value in the nodes of the main grid. This problem is solved using a two-dimensional spline function.

Background: Review of the Iraqi literatures reviled that there are several works have been done on the gastrointestinal tract of Iraqi birds, but we didn’t find research work include details information related with the gastrointestinal tract of common wood pigeon from Iraqi environment
Aim: The current study aimed to investigate the anatomy and histology of intestine in wood pigeon (Columba palumbus).
Materials and methods: Animals were collected from Al-Najaf desert, methods of Humason and Bancroft and Stevens were employed for the histological study.
Results: Anatomical results reviled that the intestine of common wood pigeon divided into several parts represented by duodenum, ileum, and rectum. Histologically the wall of all parts of intestine in common wood pigeon as in all other birds possessed four layers (mucosa, sub-mucosa, muscularis externa, and serosa). The structural differences of duodenum were in the villi which were represented by long extensions from the epithelium of the mucosa. Results showed that the ileum in common wood pigeon showed that villi of ileum were shorter than those of duodenum, and appeared as a leaf-like shape. Large intestine in wood pigeon represented by rectum which exhibit different features in the mucosa, as the villi of rectum are flat and wide (leaf-like shape),and the lumen of rectum was wider than that of small intestine.
Conclusion: the present study reviled some differences in the mucosa of rectum as the villi appeared flat leaf-like shape and the lumen was wider than that of small intestine. The mucosal epithelium represented by simple columnar epithelium, with numerous goblet cells scattered in the epithelium
Race Against Time: Afrofuturism and Our Liberated Housing Futures
Authors: Phillips Rasheedah 
Published: August 2023

Class oppression and institutional racism are reinforced by the union between time, temporality, and the law, and yet, these areas are underexamined in critical writing in legal discourse. These relationships play a daily and crucial role in how Black people—particularly those standing at the intersections of marginalized identities of gender and class—are valued, treated, punished, or underserved by and within the legal system. Closer attention paid to the temporal structures, times, and rhythms of the law and legal systems can inform legal perspectives, legal rights, and the impact of future law-making on poor and historically-marginalized communities in very real, practical, and specific ways. To go even further, I argue that utilizing Afrofuturist tools and ways of viewing time can reconfigure our assumptions of space, time, and justice, to construct law and policy solutions that facilitate equitable access to the temporal domain of the future for communities and people typically denied that access.
After introducing some examples of law and time’s convergence, I reflect briefly in Part II on how temporal inequalities and systemic temporal inequities are constructed through law and policy to have a disparate negative impact on Black people and communities. In Part II, I consider the temporalities of redevelopment in marginalized communities, where time is condensed, public memory is erased, community temporalities are disrupted, and access to temporal domains of the future are foreclosed or proscribed by government entities. In Part III, I highlight some directions and hopes for the future(s), including Afrofuturistic policy advocacy tools and approaches that work to extend, preserve, expand, and protect community time and space. Afrofuturism is considered as praxis, spatiotemporal consciousness, and tool for activating healthy and hopeful alternative temporalities in marginalized Black communities living under temporal oppression, temporal-spatial poverty, and persistent temporal-spatial discrimination and colonization of the futures of our communities.

Deep Learning and Imbalance Handling on Movie Review Sentiment Analysis
Authors: Utami Sri , Lhaksmana Kemas Muslim , Sibaroni Yuliant 
Published: August 2023

Before watching a movie, people usually read reviews written by movie critics or regular audiences to gain insights about the movie’s quality and discover recommended films. However, analyzing movie reviews can be challenging due to several reasons. Firstly, popular movies can receive hundreds of reviews, each comprising several paragraphs, making it time-consuming and effort-intensive to read them all. Secondly, different reviews may express varying opinions about the movie, making it difficult to draw definitive conclusions. To address these challenges, sentiment analysis using CNN and LSTM models, known for their effectiveness in classifying text in various datasets, was performed on the movie reviews. Additionally, techniques such as TF-IDF, Word2Vec, and data balancing with SMOTEN were applied to enhance the analysis. The CNN achieved an impressive sentiment analysis accuracy of 98.56%, while the LSTM achieved a close 98.53%. Moreover, both classifiers performed well in terms of the F1-score, with CNN obtaining 77.87% and LSTM achieving 78.92%. These results demonstrate the effectiveness of the sentiment analysis approach in extracting valuable insights from movie reviews and helping people make informed decisions about which movies to watch.
Hearing aids with tinnitus sound support reduce tinnitus severity for new and experienced hearing aid users

Published: August 2023

ObjectiveThis interventional study tested the hypothesis that hearing aids with a tinnitus sound support feature would reduce the impact of tinnitus for both new and experienced hearing aid users over a 12-week trial period.MethodsA total of 19 experienced hearing aid users and 21 participants with no previous hearing aid experience completed the study. Hearing aids were fitted and dispensed with tinnitus masking sounds adjusted to individual preferences. The primary outcome measure was the Tinnitus Functional Index (TFI) score change between baseline and the end of the 12-week trial. This trial was registered on the Australian New Zealand Clinical Trials Registry, trial ID: ACTRN12621001754831.ResultsThe TFI scores and secondary measures indicated significant improvements (reductions in tinnitus impact) at the end of the trial compared to the baseline for both experienced and new hearing aid users. Since no group differences were observed, pooled data are presented in this study. The median TFI total score before treatment was 49.0 (IQR = 40.0), and the median TFI total score after treatment was 26.0 (IQR = 26.0). A significant reduction (p = 0.0001) in the total TFI score of 24 points was observed after treatment, producing a large effect size (d = 0.60).ConclusionsThe results confirm previous findings that hearing aids assist in reducing the impact of tinnitus on daily life. The Oticon miniRITE R combination hearing aids used in this study resulted in similar improvements for both new and existing hearing aid users. This suggests that the tinnitus-reducing effects of these aids were greater than those already being used by participants.

Objectives: The goal of this project is to explore the views, expectations and preferences of patients with an unruptured intracranial aneurysm regarding the use of AR in patient education.Methods: To gain an in-depth understanding of the patients’ perspective, a face-to-face interview study was conducted using an interview protocol with a predefined topic list. All interviews were audio-recorded and transcribed verbatim afterwards. Transcripts were analyzed using thematic content analyses. Coding was performed using Atlas.ti software.Results: Seventeen interviews were conducted. The views, expectations and preferences of patients regarding patient education with AR could be subdivided into 15 categories, which could be grouped into 4 general themes: 1) experiences with current patient education, 2) expectations of AR in patient education, 3) opportunities and limitations of AR, and 4) out-of-hospital use of an AR application. Patients’ expectations were predominantly positive regarding improving patients’ understanding of their medical situation and doctor-patient communication.Discusssion: This study suggests that patients with unruptured intracranial aneurysms are open to receive patient education regarding their disease with AR. Patients expect that AR models can help patients with intra-cranial aneurysms better understand their disease, treatment options and risks. Additionally, patients expect AR could improve doctor-patient communication.

Being the sixth most diagnosed cancer and the fourth leading cause of cancer-related deaths worldwide, liver cancer is considered as a serious disease with a high prevalence and poor prognosis. Current anticancer drugs for liver cancer have drawbacks, such as limited efficacy in later stages of the disease, toxicity to healthy cells, and the potential for drug resistance. There is ample evidence that coumarin-based compounds are potent anticancer agents, with numerous analogues currently being investigated in preclinical and clinical studies. The current study aimed to explore the antitumor potency of a new class of 8-methoxycoumarin-3-carboxamides against liver cancer. Toward this aim, we have designed, synthesized, and characterized a new set of N-(substituted-phenyl)-8-methoxycoumarin-3-carboxamide analogues. The assessment of antitumor activity revealed that the synthesized class of compounds possesses substantial cytotoxicity toward Hep-G2 cells when compared to staurosporine, without significant impact on normal cells. Out of the synthesized compounds, compound 7 demonstrated the most potent cytotoxic effect against Hep-G2 cells with an IC50 of 0.75 µM, which was more potent than the drug staurosporine (IC50 = 8.37 µM). The investigation into the mechanism behind the antiproliferative activity of compound 7 revealed that it interferes with DNA replication and induces DNA damage, leading to cell cycle arrest as demonstrated by a significant decrease in the percentage of cells in the G1 and G2/M phases, along with an increase in the percentage of cells in the S phase. Flow cytometric analysis further revealed that compound 7 has the ability to trigger programmed cell death by inducing necrosis and apoptosis in HepG-2 cells. Further explorations into the mechanism of action demonstrated that compound 7 displays a potent dual-inhibitory activity toward cytochrome P450 and vascular endothelial growth factor receptor-2 (VEGFR-2) proteins, as compared to sorafenib drug. Further, detailed computational studies revealed that compound 7 displays a considerable binding affinity toward the binding cavity of VEGFR2 and CYP450 proteins. Taken together, our findings indicate that the newly synthesized class of compounds, particularly compound 7, could serve as a promising scaffold for the development of highly effective anticancer agents against liver cancer.
Reasons for ceiling ratings in real-life evaluations of hearing aids: the relationship between SNR and hearing aid ratings
Authors: Schinkel-Bielefeld Nadja , Ritslev Jana , Lelic Dina 
Published: August 2023

IntroductionIn past Ecological Momentary Assessment (EMA) studies, hearing aid outcome ratings have often been close to ceiling.MethodsTo analyze the underlying reasons for the very positive ratings, we conducted a study with 17 experienced hearing aid wearers who were fitted with study hearing aids. The acceptable noise level and the noise level where participants were unable to follow speech were measured. The participants then rated hearing aid satisfaction, speech understanding and listening effort for pre-defined SNRs between −10 and +20 dB SPL in the laboratory. These ratings were compared to ratings of a two-week EMA trial. Additionally, estimates of SNRs were collected from hearing aids during the EMA trial and we assessed whether the participants experienced those SNRs rated poorly in the laboratory in real life.ResultsThe results showed that for hearing aid satisfaction and speech understanding, the full rating scale was used in the laboratory, while the ratings in real life were strongly skewed towards the positive end of the scale. In the laboratory, SNRs where participants indicated they could not follow the narrator (“unable to follow” noise level) were rated clearly better than the lowest possible ratings. This indicates that very negative ratings may not be applicable in real-life testing. The lower part of the distribution of real-life SNR estimates was related to participants’ individual “unable to follow” noise levels and the SNRs which were rated poorly in the laboratory made up less than 10% of the speech situations experienced in real life.DiscussionThis indicates that people do not seem to frequently experience listening situations at SNRs where they are dissatisfied with their hearing aids and this could be the reason for the overly positive hearing aid outcome ratings in EMA studies. It remains unclear to what extent the scarcity of such situations is due lack of encounters or intentional avoidance.
