Background: Uterine smooth muscle tumors of uncertain malignant potential (STUMPs) are a rare tumor that represent a diagnostic challenge to both clinicians and pathologists. Hysterectomy is considered the definitive treatment in women who don’t desire to conceive anymore; while myomectomy is suggested in young women who desire to preserve their fertility. The aim of this review is to evaluate the reproductive outcomes in patients submitted to fertility sparing treatment and with a diagnosis of STUMP at the definitive pathological evaluation. Methods: We searched among electronic databases from inception of them through January 2022. The research was conducted using meshes created by the combination of relevant heading term, key words, and word variants for: “uterine smooth muscle tumor of uncertain malignant potential”, “fertility”, “pregnancy”. Results: Seven retrospective studies including 80 women desirous of conceiving after a diagnosis of STUMP were included in this systematic review. Among these, 33 (41.25%) women got pregnant at least once and we recorded a total number of pregnancies of thirty-nine. Almost all deliveries were performed by caesarean section. Two (6.1%) relapses were diagnosed. Patients were submitted to hysterectomy and STUMP was confirmed as the final pathological diagnosis. The median follow-up in patients who delivered live babies was 61 months after surgery. At the last follow-up, all patients were alive without evidence of disease. Conclusions: This review shows that pregnacy seems to be possible and safe after the diagnosis of STUMP. These women should undergo rigorous follow-up and consider hysterectomy after completion of their reproductive plan. This review could be a useful tool for the counseling and the management of women with STUMP who desire to keep their fertility.

Published: December 2022

Background: Cesarean Scar Pregnancy (CSP) is a cause of severe maternal morbidity. Currently, no guideline for its management is shared. We assessed safety and effectiveness of Methotrexate (MTX) administration within the sub-chorionic space under hysteroscopic guidance, followed by resectoscopic placental removal. Methods: Five patients suffering from type 2 CSP underwent a sequential treatment based on hysteroscopic techniques. Pregnancy termination was firstly obtained by injection of 80 mg of MTX within the intervillous spaces of placental site. The intervention was performed in an office setting using a 16Fr hysteroscope. MTX was administered by a 17-gauge needle suitable for the operative channel of hysteroscope. Subsequently, based on the decline of Human Chorionic Gonadotropin β-subunit (β-HCG), we timed a placental removal using a 27-Fr resectoscope, under conscious sedation. Results: In all women a diagnosis of CSP was achieved between 6 and 8 gestational age weeks. Hysteroscopic MTX administration resulted easily, quickly, painlessly and uneventfully in all patients. A substantial decrease of β-HCG was obtained in all patients within 15 days from the MTX administration. After a mean time of 27 days from MTX a resectoscopic removal of CSP was carried-out without any recorded adverse outcome. After 30 days from surgery β-HCG returned to non-pregnant level and normal physical findings were found in all patients. Conclusions: Hysteroscopy-guided MTX sub-chorionic administration resulted safe and effective for CSP termination. It was followed by successful and uneventful resectoscopic placenta removal in all patients. When hysteroscopy facilities are available, this combined therapy can be an option to treat CSP.

Authors: Luo Ping , Ming Zizhen , Yang Zhiwen
Published: December 2022

The adaptor protein Caspase Recruitment Domain Family Member 9 (CARD9) plays an indispensable role in innate immunity. Recent studies indicate that dysregulated CARD9 is a critical risk factor in the progression of colorectal cancer (CRC). This review provides novel insights into the functions of CARD9 in CRC, particularly in delineating its role in disrupting the host microbe balance, fueling gut microbiota metabolism and inducing systemic immunoglobulin G (IgG) antifungal antibodies. These pathways provide important information that can potentially be used for therapeutic innovation in developing potential vaccines for CRC.
RASIONALITAS TURKI MENYEPAKATI GENCATAN SENJATA DENGAN RUSIA DALAM KONFLIK INTERNAL SURIAH
Authors: Penulis
Published: December 2022

This study discusses Turkey's rationality in agreeing a ceasefire agreement with Russia in the Syrian internal conflict. The Rational Actor Model Theory by Graham T. Allison is used to help researchers analyze the rationalization steps used by Turkey to finally agree on a ceasefire with Russia on March 5, 2020. This study uses an explanatory research type with qualitative methods, and the level of nation-state analysis. Sources of data used are secondary data in the form of literature studies obtained through books, journals, articles, and news that are accessed online. Before finally agreeing with Russia to carry out a ceasefire in the Idlib region, Turkey has gone through four stages/components of RAM in order to get the results or outputs of its rational actions in the Syrian conflict. The four components are, Goals and Objectives, Alternatives, Consequences, and Choices. Turkey is faced with two choices, namely to agree or not to agree. In the end, Turkey chose to agree to a ceasefire agreement with Russia, where the results obtained from the rationalization of Turkey agreed to the ceasefire, namely to prevent the flow of refugees from getting bigger into the country, overcoming the humanitarian crisis as a result of the battle with the Assad regime forces in Idlib, and maintaining its territorial sovereignty.

Published: December 2022

Objective: Self-reported memory difficulties are common among older adults, but few studies have examined memory problems among autistic middle-aged and older people. The current study examines self-rated prospective (PM) and retrospective (RM) memory difficulties and their associations with age in middle-aged and older autistic and non-autistic people.Methods: 350 autistic people (58% assigned-female-at-birth; age-range: 40-83 years) and 350 non-autistic adults matched on age, birth-sex and education level were included in the analysis. Participants completed the Prospective and Retrospective Memory Questionnaire (PRMQ) which includes questions about PM vs. RM (memory type), environment-cued vs. self-cued (cue), and short vs. long delay (delay). Results: Autistic people reported significantly more PM and RM difficulties than the comparison group. Both groups reported more difficulties with PM (vs. RM), self-cued (vs. environment-cued), and short (vs. long) delay. No significant interactions were observed. Among autistic people, younger age was associated with reporting more PM and RM difficulties, but this pattern was not observed among non-autistic people. Conclusions: Autistic people may be at reduced risk for memory problems as they age, compared to their same-age non-autistic peers. Further studies are required to explore the association between self-reported memory challenges and memory task performance among autistic older people.

Turki menerapkan Open Door Policy kepada pengungsi Suriah untuk menerima pengungsi untuk tinggal di wilayahnya. Pro dan kontra antara pemerintah dan pihak oposisi yang tidak menyetujui akan hadirnya pengungsi Suriah di Turki. Penulis menggunakan pendekatan kualitatif dengan tipe eksplanatif, melalui metode wawancara, library research dan penelusuran data online berdasarkan kebijakan luar negeri menurut Marijke Breuning untuk menganalisa kasus tersebut. Hasil penelitian menunjukkan bahwa penerapan Open Door Policy terhadap krisis kemanusiaan pengungsi Suriah didasarkan atas beberapa alasan yakni personalitas Erdogan sebagai pemimpin Turki, komitmen terhadap Humanitarian Based Approach, komitmen terhadap Konvensi Jenewa 1951 dan Protokol 1967, pengaruh partai AKP, kesempatan Turki menjadi anggota Uni Eropa, mensupport terhadap warga Suriah, komitmen terhadap Zero Problem with Neighbours. Implementasinya berupa pembangunan kamp-kamp pengungisan, penjaminan pendidikan, kesehatan, psikososial serta lapangan pekerjaan, bekerjasama dengan negara-negara lain dan organisasi internasional. Sedangkan dampaknya berupa citra Turki membaik di skala global dan dunia muslim, kedatangan arus pengungsi dalam jumlah yang besar, pecahnya warga Turki yang pro dan kontra terhadap kebijakan, adanya serangan dari PKK, tantangan sosio- ekonomi, tantangan sosio kultur, keterlibatan Turki dalam Astana Talks, dan melakukan operasi militer di Utara Suriah.
Systemic Vulnerabilities in Hispanic and Latinx Immigrant Communities Led to the Reliance on an Informal Warning System in the December 10–11, 2021 Tornado Outbreak
Authors: Trujillo-Falcón Joseph , Gaviria Pabón América , Reedy Justin , Klockow-McClain Kim
Published: December 2022

On December 10–11, 2021, the deadliest December tornado outbreak on record produced a family of EF4 tornadoes that severely impacted communities in Arkansas, Kentucky, Missouri, and Tennessee. Although the National Weather Service anticipated the outbreak three days earlier, not all communities received life-saving information before, during, or after the disaster. To examine systemic vulnerabilities experienced by Hispanic and Latinx immigrant populations, our team conducted a week-long field study in areas directly impacted by significant tornadoes. Connecting with local organizations, we interviewed 25 immigrants and community leaders in Arkansas and Kentucky. Social and systemic vulnerabilities, such as English proficiency, immigration status, and varying cultures of disaster preparedness are examined as potential blockades to inclusive disaster response. Themes are contextualized into Mileti and Sorensen’s warning response model. Findings indicate that US Hispanic and Latinx immigrants relied mainly on unofficial sources that had no expertise in severe weather forecasting and communication, prolonging their time to effectively respond to tornadoes and take proper protective actions. We conclude with practical recommendations for developing a multilingual emergency alert system that integrates community leaders and underserved groups.
Reward feedback enhances sustained attention on short timescales
Authors: Trach Juliana , deBettencourt Megan T , Radulescu Angela , McDougle Samuel D
Published: December 2022

Attention and learning are intertwined. While previous work has primarily examined how the focus of attention can shape learning, how the dynamics of learning might impact your attentional state on a moment-to-moment basis is an open question. Here we leverage reinforcement learning theory to investigate the influence of rewards and reward prediction errors on attentional vigilance. Specifically, we ask how trial-by-trial reward prediction errors, which are the currency of the RL system and the primary behavioral correlate of dopaminergic activity, affect attentional vigilance. Using a task that simultaneously assessed people’s attentional vigilance and RL performance, we demonstrate that attentional state is influenced by both the magnitude and valence of recent reward prediction errors, with attention covarying with signed reward prediction errors. These findings demonstrate that rewards – and surprising ones in particular – reduce lapses and improve attentional vigilance. By highlighting a robust interaction between core computations of the RL system and attentional dynamics, these findings may provide preliminary evidence for a potential role of dopamine in mediating the relationship between learning and attention.

ЗАЧЕМ РОССИЙСКИЕ ИСТОРИКИ ПРИВЕТСТВУЮТ ПРЕСЛЕДОВАНИЕ КОЛЛЕГ И ПОДДЕРЖИВАЮТ МАССОВОЕ ОГРАНИЧЕНИЕ ДОСТУПА К АРХИВНЫМ ИСТОЧНИКАМ?!

Published: December 2022

Аннотация. В оценке открытости российских архивов для исследователей политическая воля властей зачастую воспринимается как решающее обстоятельство, влияющее на доступ к документам. В то же время позиция историков, как и общественных деятелей, способных формулировать учитываемый политиками запрос, берётся в расчет значительно реже. При ближайшем рассмотрении выясняется, что лица, возглавляющие общественные организации, а также способные влиять на ситуацию в профессиональной среде, придерживаются охранительной позиции, сопряженной с продлением запретов – особенно связанных с доступом к документам, отражающим деятельность советской госбезопасности. Поскольку сообществу профессиональных историков не хватает самоорганизации либо волевых качеств для того, чтобы, проявив корпоративную солидарность, объединиться перед угрозами, упраздняющими научную независимость исследователей, а либеральная риторика не гарантирует того, что использующие её деятели не прикрывают ею соучастие в гонениях, актуализируется вопрос о том, как и почему исследовательское сообщество не сумело эффективно помешать российским политикам эффективно использовать историю для осуществляемого Кремлём идеологического реванша. Сопоставление публичных деклараций с закулисными действиями известных российских историков, журналистов и общественных деятелей позволяет обозначить ряд причин, по которым историческая наука в России вновь отдаётся на откуп властям, рассматривающим эту профессию как разновидность политработы. Ряд эпизодов, свидетелем которых довелось стать автору статьи, предаётся огласке впервые, дополняя уже известные по публикациям высказывания, открыто подыгрывающих властям историков и политиков.

Methods of Translation of Official-Business Terminology of the World Trade Organisation
Authors: Demianchuk Yu.
Published: December 2022

The scientific article is devoted to substantiation of actual methods of translation of official-business terminology of the World Trade Organization (hereinafter referred to as WTO) and identification and systematization of regularities of its lexical-semantic, stylistic and linguistic-cultural manifestations in English-language official-business texts. The variety of special terminology and the main methods of its translation are a main area of study among translators. Therefore, it is important to pay attention to those translation methods that most fully interpret the various features of special lexemes in official business documents (hereinafter referred to as OBD). The specifics of the representation of methods of translation of official business terminology of the WTO are characterized by their peculiarities, which allows the separation of numerous terms from the official business text and stimulates scientific interest in their study and search for appropriate language means – for their nomination. In the official business texts of the WTO, the translation of terminology is realized through current translation transformations, which fit into the official business style, and the preference is given to the most common types of transformations. The scientific article proposes a comprehensive method of analysis of the official business text, as well as the appropriate translation methodology, which explicates the idea of economic terminology by means of official business language. The results of the applied study show that the opposition of English and Ukrainian special terms in the official business text of the WTO is explained by differences in semantic and syntactic structure of the sentence and the order of components of expression: on the one hand, these are grammatical and semantic differences, and on the other hand, typological differences between English and Ukrainian languages.

Authors: El Abasse Zeine , Mhamed Ethman Sid , Eba Ahmed
Published: December 2022

Background: The stenosis of the ostial left anterior descending artery represents one of the challenges for the interventional cardiologist. In contrast ostial stenosis of the left main trunk shows very good results after percutaneous interventions and implantation of drug-eluting stents. The indications for percutaneous transluminal coronary angioplasty (PTCA) of an ostial lesion correspond to the indications for treatment of all other lesions. Case: A-56-year-old woman was admitted to our hospital who was initially admitted in the intensive care unit for a severe acute chest pain. She had no coronary risk factors. No hormonal disorders were observed. Physical and laboratory examinations revealed that she had not suffered from syphilis or aortitis syndrome or any other inflammatory diseases. An electrocardiogram (ECG) was immediately performed and showed ST segment non elevation in the precordial leads (Figure 1) suggesting an acute anterior ST Non elevation myocardial infarction (NSTEMI). On coronary angiography, a 80% stenosis of the left coronary ostial stenosis was found, but no abnormality was found in other arterial trees. (Figure 2) The patient was diagnosed as having isolated coronary ostial stenosis. Conclusion: The patients are almost always middle aged woman with no coronary risk factors. , the involved coronary artery is the left main coronary artery, so its obstruction results in a serious condition. Therefore, though its pathogenesis remains to be determined, isolated left coronary ostial stenosis seems to be a distinct clinical entity.

Abstract. Bronchial asthma ( BA) is one of the most common diseases of the human respiratory organs and occupies one of the leading places both in the terms of the prevalence and the severity of manifestations. With a long duration of BA, concomitant smoking, the irreversible bronchial obstruction formation, some patients develop pulmonary emphysema. The pathogenesis of pulmonary emphysema is multifactorial and consists in the mechanisms of oxidative stress, imbalance of the protease/antiprotease system, activation of inflammatory cells and production of inflammatory mediators. Oxidative stress is one of the main processes in the formation of pulmonary emphysema, but its exact mechanisms, which could be targeted by pathogenetic therapy, have not yet been studied. The study of pulmonary emphysema pathogenesis in patients is often complicated due to the influence of a large number of random combinations of the various factors. One way to avoid such influence is experiment. The aim is to study the nature of changes in the oxidant-antioxidant system of the blood in the experimental pulmonary emphysema. Methods. Experimental studies were carried out on 24 mature, outbred white rats weighing 180-200 g, which were kept on a standard vivarium diet. To assess the intensity of lipid peroxidation in the animal blood, the content of its final product, malondialdehyde, was determined. The the antioxidant system activity was assessed by the content of ceruloplasmin and catalase activity in the blood. Results. The results of the conducted studies indicate a significant increase in the level of malondialdehyde in the blood in conditions of experimental pulmonary emphysema by 30 %. At the same time, a decrease in the content of ceruloplasmin in the blood by 20 % and catalase activity by 29 % was revealed. Conclusions. In experimental pulmonary emphysema, enhanced generation of malondialdehyde leads to the development of oxidative stress and intoxication, disruption of the functions of the antioxidant and antiperoxide defense systems of the body, as evidenced by the significant decrease in the level of ceruloplasmin and catalase activity in the blood.

Authors: Willian Nancy , Pardi Hilfi , Arief Syukri
Published: December 2022

This study investigated the single-step synthesis and antibacterial activity of gold nanoparticles (GNPs), produced using leaves aqueous extract of Mangrove Rhizophora stylosa. The reaction of the extract with chloroauric acid caused a reduction of auric chloride and the formation of GNPs in 60 minutes at room temperature. The size, shape, and elemental composition of the nanoparticles (NP) were studied using a transmission electron microscope (TEM) with an average particle size of 27 nm with the dominant shape being spherical and partly hexagonal, and trigonal. X-Ray Diffraction (XRD) analysis showed gold crystals with 4 diffraction peaks with PCC crystalline nature. UVvis spectroscopy shows the SPR peaks found in the wavelength range of 530-546 nm. Furthermore, the NP biological capping agents identified by Fourier-transform infrared spectroscopy (FT-IR) were carbonyl, amine, and polyphenol. Leaf extract serves as an effective bio-reducing agent for the synthesis of GNPs. The results showed that the GNPs synthesized using Rhizophora stylosa mangrove aqueous extract had the potential for antibacterial activity.

The kinetics of the formation of carbon nanotubes on a catalyst during the pyrolysis of carbon-containing gases is rather peculiar and little studied. Its main provisions proposed in the literature are debatable. The complexity of studying the kinetics of NT synthesis is confirmed by the use of about 10 parameters when creating a model. The kinetic regularities of the formation of carbon nanotubes during the pyrolysis of methane are studied in terms of the yield of carbon at the optimal composition of the catalyst.

Published: December 2022

In a wide range of changes in the concentration of the initial components, the influence of the components of the initial substances on the patterns of formation of a gas-sensitive material was studied. It was found that the initial solution has the highest stability (18.5 days) at the ratio of contents: TEOS: water: ethanol: HCI=1:20: 30: 0.05. As a result of the study of the regularities of sol-gel synthesis of semiconductor gas-sensitive materials based on tetraethoxysilane and metal oxides Zn, Ti, and W, the following highly efficient gas-sensitive materials were selected, and the optimal operating temperature for the sensitive elements of semiconductor sensors H2S, NH3, and CH4: H2S (topt.=350°C; 95WO3+5CuO), NH3 (topt.=350 °C; 95TiO2+5Fe2O3), CH4 (topt.= 400°C; 90ZnO+10CoO). The results obtained were used in the development of thin-film semiconductor ssensors for H2S, NH3, and CH4 with a substrate based on a spiral of a glazed platinum microwire. The metrological parameters of sensors based on gassensitive materials synthesized with and without a template (polyethylene glycol) were studied during the experiments. It has been found that the sensitivity of a metal oxide composite film obtained in the presence of a template in the determination of H2S, NH3, and CH4 is higher than that of a film obtained without a template.

The 11 provinces on the banks of the Yangtze River Economic Belt are used as the research object to construct low-carbon logistics. The performance evaluation model evaluates the performance of regional low-carbon logistics. Based on this, suggestions for low-carbon development in the Yangtze River Economic Zone are put forward and provide a theoretical basis for the development of low-carbon logistics in the Yangtze River Economic Zone.
Non-collapse of the effective Wadge hierarchy
Authors: Selivanov Victor
Published: December 2022

We study the recently suggested effective Wadge hierarchy in effective spaces, concentrating on the non-collapse property. Along with hierarchies of sets, we study hierarchies of k-partitions which are interesting on their own. In particular, we establish sufficient conditions for the non-collapse of the effective Wadge hierarchy and apply them to some concrete spaces, including the discrete space of natural numbers, the Baire space, and the Cantor space. While the latter two cases are obtained by easy effectivization of the corresponding topological result by T. Kihara and A. Montalban, the first case needs a different technique and is certainly the main technical result of this paper.
Precedential Constraint Derived from Inconsistent Case Bases
Authors: Canavotto Ilaria
Published: December 2022

I explore a factor-based model of precedential constraint that, unlike existing models, does not rely on the assumption that the background set of precedent cases is consistent. The model I consider is a generalization of the reason model of precedential constraint that was suggested by Horty. I show that, within this framework, inconsistent case bases behave in a sensible and interesting way, both from a logical and a more practical perspective.
Stable Normative Explanations
Authors: Governatori Guido , Olivieri Francesco , Rotolo Antonino , Cristani Matteo
Published: December 2022

Modelling the concept of explanation is a central matter in AI systems, as it provides methods for developing eXplainable AI (XAI). When explanation applies to normative reasoning, XAI aims at promoting normative trust in the decisions of AI systems: in fact, such a trust depends on understanding whether systems predictions correspond to legally compliant scenarios. This paper extends to normative reasoning a work by Governatori et al. (2022) on the notion of stable explanations in a non-monotonic setting: when an explanation is stable, it can be used to infer the same normative conclusion independently of other facts that are found afterwards.

Published: December 2022

Topic modeling is widely used in various domains for extracting latent topics underlying large corpora, including judicial texts. In the latter, topics tend to be made by and for domain experts, but remain unintelligible for laymen. In the framework of housing law court decisions in French which mixes abstract legal terminology with real-life situations described in common language, similarly to [1], we aim at identifying different situations that can cause a tenant to prosecute their landlord in court with the application of topic models. Upon quantitative evaluation, LDA and BERTopic deliver the best results, but a closer manual analysis reveals that the second embedding-based approach is much better at producing and even uncovering topics that describe a tenant’s real-life issues and situations.

This paper presents a secure image authentication scheme for tamper localization and recovery at pixel level. The proposed scheme encrypts the watermark comprising tamper localization code and self-recovery code using chaotic sequence to ensure security. This scheme uses pixel to block conversion technique for ensuring lossless recovery of the original image from an untampered watermarked image. For enhancing the localization accuracy, a multilevel tamper localization strategy is used. The experimental results show that the proposed scheme generates watermarked images with minimal information loss and can withstand copy-move, image splicing, content removal, vector quantization, collage and content only attacks. This scheme has better security, better tamper localization accuracy and better recovered image quality under extensive tampering and takes less computation time in comparison to the state-of-the-art schemes.

The construction industry is the basic industry of the country. With the rapid development of the economy, the construction industry has grown rapidly and the competition in the construction market has become more intense. The competition in the construction market is not only between individual enterprises, but also between the whole supply chain that provides products. Therefore, it is imperative to introduce the idea of supply chain management, strengthen the cooperation with suppliers and improve competitiveness. Supplier evaluation and selection is one of the first issues to be solved for the development of supply chain management. The selection and application of building material suppliers is a classic multiple attribute decision making (MADM). In this paper, the intuitionistic fuzzy sets (IFSs) and Hamacher operations is introduced and the induced intuitionistic fuzzy Hamacher power ordered weighted average (I-IFHPOWA) operator is built. Meanwhile, the properties of built operator are analyzed. Then, the I-IFHPOWA operator is applied to solve the MADM under IFSs. Finally, an example for building material supplier selection is utilized to proof this built model.
On hybrid k-ideals in semirings

Many uncertainties arise in real-world problems, making them impossible to solve using conventional approaches. Researchers all over the world have developed new mathematical theories like fuzzy set theory and rough set theory to better understand the uncertainties that occur in various fields. Soft set theory, which was recently introduced, offers a novel approach to real-world problem solving by removing the need to set the membership function. This is helpful in resolving a variety of issues, and much progress is being made these days. Recently, Jun introduced the concept of a hybrid structure, which blends the concepts of a fuzzy set as well as a soft set. In this paper, we define the hybrid k-sum and hybrid k-product of k-ideals of semiring and investigate their properties. We illustrate with an example that the hybrid sum and hybrid product of two k-ideals are not always hybrid ideals. We also describe semiring regularity constraints in terms of hybrid k-ideal structures.
A topological approach for improving accuracy in decision-making via bi-ideal approximation
Authors: Kaur Kamalpreet , Gupta Asha
Published: December 2022

The present paper proposes a novel version of inducing nano topology by using new kinds of approximation operators via two ideals with respect to a general binary relation. This approach improves the accuracy of the approximation quite significantly. These newly defined approximations constitute the generalized version of rough sets defined by Pawlak in 1982. A comparison is drawn between the suggested technique and the already existing ones to demonstrate the significance of the proposed ideology. In addition, the standard notion of nano topology, based on an equivalence relation is generalized to the binary relation, which can have a broader scope when applied to intelligent systems. Also, the significance of this approach is demonstrated by an example where an algorithm is given to find the key factors responsible for the profit of a company along with the comparison to the previous notions. Likewise, the proposed algorithm can be used in all fields of science to simplify complex information systems in extracting useful data by finding the core.
Low light color balancing and denoising by machine learning based approximation for underwater images

Published: December 2022

It is difficult for underwater archaeologists to recover the fine details of a captured image on the seabed when the image quality worsens due to the presence of more noisy artefacts, a mismatched device colour map, and a blurry image. To resolve this problem, we present a machine learning-based image restoration model (ML-IRM) for improving the visual quality of underwater images that have been deteriorated. Using this model, a home-made bowl set-up is created in which a different liquid concentration is used to replicate seabed water variation, and an object is dipped, or a video is played behind the bowl to recognise the object texture captured image in high-resolution for training the image restoration model is proposed. Gaussian and bidirectional pre-processing filters are used to both the high and low frequency components of the training image, respectively. To improve the clarity of the high-frequency channel background, soft-thresholding decreases the presence of distracting artefacts. On the other hand, the ML-IRM model can effectively keep the object textures on a low frequency channel. Experiment findings show that the proposed ML-IRM model improves the quality of seabed images, eliminates colour mismatches, and allows for more detailed information extraction. Blue shadow, green shadow, hazy, and low light test samples are randomly selected from all five datasets including U45 [1], EUVP [2], DUIE [3], UIEB [4], UM-ImageNet [5], and the proposed model. Peak Signal to Noise Ratio (PSNR) and Structural Similarity Index (SSIM) are computed for each condition separately. We list the values of PSNR (at 16.99 dB, 15.96 dB, 18.09 dB, 15.67 dB, 9.39 dB, 17.98 dB, 19.32 dB, 14.27 dB, 12.07 dB, and 25.47 dB) and SSIM (at 0.52, 0.57, 0.33, 0.47, 0.44, and 0.23, respectively. Similarly, it demonstrates that the proposed ML-IRM achieves a satisfactory result in terms of colour correction and contrast adjustment when applied to the problem of improving underwater images captured in low light. To do so, high-resolution images were captured in two low-light conditions (after 6 p.m. and again at 6 a.m.) for the training image datasets, and the results of their observations were compared to those of other existing state-of-the-art-methods.
A multi-resolution unet algorithm based on data augmentation and multi-center training for polyp automatic segmentation
Authors: He Xiaoxu
Published: December 2022

In clinical practice, segmenting polyps from colonoscopy images plays an important role in the diagnosis and treatment of colorectal cancer since it provides valuable information. However, accurate polyp segmentation is full of changes due to the following reasons: (1) the small training datasets with a limited number of samples and the lack of data variability; (2) the same type of polyps with a variation in texture, size, and color; (3) the weak boundary between a polyp and its surrounding mucosa. To address these challenges, we propose a novel robust deep neural network based on data augmentation, called Robust Multi-center Multi-resolution Unet (RMMSUNet), for the polyp segmentation task. Data augmentation and Multi-center training are both utilized to increase the amount and diversity of training dataset. The new multi-resolution blocks make up for the lack of fine-grained information in U-Net, and ensures the generation of more accurate pixel-level segmentation prediction graphs. Region-based refinement is added as the post-processing for the network output, to correct some wrongly predicted pixels and further refine the segmentation results. Quantitative and qualitative evaluations on the challenging polyp dataset show that our RMMSUNet improves the segmentation accuracy significantly, when comparing to other SOTA algorithms.

BACKGROUND: Paid work during high school serves as a steppingstone to postsecondary employment for young adults with severe disabilities. Yet, youth with significant cognitive impairments rarely have the opportunity to experience paid work during high school. OBJECTIVE: The purpose of this study was to identify the range of facilitators that promote paid employment for youth with severe disabilities during high school. METHODS: We conducted individual and focus group interviews with 74 special educators, adult agency providers, school district leaders, parents of youth with severe disabilities, and local employers. RESULTS: Participants discussed 36 facilitators spanning nine major categories: collaboration, training and information, attitudes and mindsets, supports for youth, youth work experiences, knowledge and skill instruction, staffing, individualization, and transportation. We identified similarities and differences in the factors emphasized by each of the five stakeholder groups. CONCLUSION: Renewed attention should be focused on key practices and partnerships needed to facilitate community-based work experiences for youth with severe disabilities prior to graduation.
