Transformed primal–dual methods for nonlinear saddle point systems
Authors: Chen Long , Wei Jingrong 
Published: January 2023

Abstract
A transformed primal–dual (TPD) flow is developed for a class of nonlinear smooth saddle point systemThe flow for the dual variable contains a Schur complement which is strongly convex. Exponential stability of the saddle point is obtained by showing the strong Lyapunov property. Several TPD iterations are derived by implicit Euler, explicit Euler, implicit–explicit, and Gauss–Seidel methods with accelerated overrelaxation of the TPD flow. Generalized to the symmetric TPD iterations, linear convergence rate is preserved for convex–concave saddle point systems under assumptions that the regularized functions are strongly convex. The effectiveness of augmented Lagrangian methods can be explained as a regularization of the non-strongly convexity and a preconditioning for the Schur complement. The algorithm and convergence analysis depends crucially on appropriate inner products of the spaces for the primal variable and dual variable. A clear convergence analysis with nonlinear inexact inner solvers is also developed.

Abstract
In the paper the binary mechanism of the long-distance image transfer in a wire-medium (WM) endoscope is suggested and studied. We have shown that a discrete image formed by a set of point sources TM-polarized with respect to the WM can be transferred from the input to the output of the endoscope in a very broad frequency band. The underlying physics is the formation of local channels by a group of four adjacent wires. It allows the transfer of the near field beyond the Fabry–Perot resonances at which the known canalization mechanism offers the image. Both numerical simulations and experimental measurements confirm the deeply subwavelength resolution on the output WM interface. The binary imaging was studied until the frequencies at which the endoscope length exceeds 5λ. The transfer is possible in the entire investigated frequency range (from 1 up to 4 GHz) except for the frequencies where the Fabry–Perot resonance are not enough suppressed.

Nonlinear computer image scene and target information extraction based on big data technology
Authors: Wang Jiaqi 
Published: January 2023

Abstract
To explore the extraction of computer image scene and target information, a nonlinear method based on big data technology is proposed. The method can decompose the computer image into a plurality of components when the SAR computer image is processed such as target extraction and computer image compression, which represent different captured image features, respectively. Selecting the most suitable processing method according to the characteristics of different components can greatly improve the performance. Using nonlinear diffusion method, the computer image is decomposed into structural components representing large-scale structural information and texture components representing small-scale detailed information, and the automatic threshold estimation in the diffusion process is studied. The LAIDA criterion is introduced into the automatic threshold solution of nonlinear diffusion-based computer image decomposition to test and evaluate the diffusion process of various diffusion parameter forms. The results show that the experimental outcome of the diffusion decomposition based on automatic threshold estimation is very close on each index, which shows that using automatic threshold estimation, no matter what diffusion index is used, very close results can be obtained. Specifically, for each algorithm, the parameter estimation threshold l for outliers plays an obvious role. The third is the degree of initiative of the estimation process. The larger the L, the larger the outlier, which will lead to a greater extent of the diffusion process, resulting in a continuous decrease in the structural similarity index and compositional correlation. It is proved that the algorithm has strong global search ability, can effectively avoid premature convergence, has fast convergence speed, and good long stability. It can be widely used for optimization of various multimodal functions.

Abstract
In order to solve the problem of bacterial resistance, increase the antibacterial performance and delay the aging of paper, the berberine modified trimethoprim carboxymethyl cellulose was prepared using trimethoprimethylate carboxymethyl cellulose as raw material and trimethoprimethylate lactate (TMP) as antibacterial modifier by Schiff Base reaction. At the same time, berberine (BBR) was used as graft monomer to prepare a multifunctional protective solution integrating strengthening, antibacterial and good biocompatibility. The optimal process conditions were determined by single factor experiment and response surface method. The structure and properties of the product were characterized by FT-IR, XRD, TG and SEM and the antibacterial properties were evaluated by AGAR disk diffusion method. The results showed that when the mass ratio of dialdehyde carboxymethyl cellulose and modified berberine was 7:15, reaction temperature was 40 °C, and pH was 6.0, the optimum synthetic conditions was obtained. And the minimum inhibitory concentration of the product against Staphylococcus aureus and Escherichia coli were 0.2 mg/mL, minimum diameter of antibacterial zone of 6.7 mm and 7.1 mm, respectively, with good antibacterial effect. This paper lays a foundation for further research on the safe and effective antiquities antibacterial agent, and provides a reference for its further development in paper protection.

Abstract

Background: A two-dimensional (2D) ultrasound examination is the primary technique for follicle monitoring, but 2D ultrasound follicle monitoring has significant inter- and intra-observer variability in the measurement of follicle diameter. The aim of this study was to propose a novel deep learning-based automated model for accurate 2D ultrasound follicle monitoring and validate the reliability and repeatability in clinical practice.

Methods: A prospective trial including 300 infertile women undergoing ovulation induction (single follicle cycles) or controlled ovarian hyperstimulation (multiple follicle cycles) was conducted in the reproductive center. After 2D ultrasound image acquisition, the mean diameter of each targeted follicle was measured using an automated model, experts, and a novice. Designating the expert assessment as the gold standard, the reliability and repeatability of the automated model for single and multiple follicle cycles were evaluated using the intraclass correlation coefficient and Bland-Altman plots.

Results: A total of 228 and 1065 follicles from single and multiple follicle cycles, respectively, were included. The accurate recognition rate of follicle boundaries using the automated model was 0.931. The inter-observer variability of follicle mean diameter measurements in single and multiple follicle cycles were 0.970 and 0.984 for the automated model and experts, and 0.965 and 0.978 for a novice and experts, respectively. Bland-Altman plots showed that 95% limits of agreement for follicle diameter measurement between the automated model and experts (−2.02 to 2.39 mm and −0.68 to 1.50 mm) was lower than a novice and experts (−1.69 to 2.74 mm and −0.58 to 1.73 mm) for both single and multiple follicle cycles. The intraclass correlation (ICC) of follicle diameters ≥10 mm calculated by the automated model was significantly higher than follicle diameters <10 mm in multiple follicle cycles (0.834 vs. 0.609). There were no significant differences between the two groups in single follicle cycles (0.967 vs. 0.970).

Conclusion: A deep learning-based automated model provides an accurate and fast approach for novices to improve the reliability and receptivity of 2D ultrasound follicle monitoring, especially in multiple follicle cycles and for follicles with a mean diameter ≥ 10 mm.

Published: January 2023

Salmonella Typhimurium is a zoonotic bacterium that can cause salmonellosis, and the major concerns of S. Typhimurium for the food industry are its ability to obtain multidrug resistance and form biofilms on food-contact surfaces. In the current study, the antimicrobial resistance of a strong biofilm former S. Typhimurium M3 was assessed by the diffusion method. Genome sequencing was also applied to obtain the genes related to antibiotic resistance, and biofilm formation of S. Typhimurium M3. Biofilm-forming capacity of S. Typhimurium M3 was found to be strain dependent, and a high number of isolates were strong biofilm formers. The high biofilm-forming isolate S. Typhimurium M3 was resistant to oxacillin, lincomycin, rifampicin, tetracycline, and clindamycin, with the MIC values of 512 μg/mL, 32 μg/mL, 16 μg/mL, 64 μg/mL, and 64 μg/mL, respectively. Genomic annotation of S. Typhimurium M3 showed the presence of genes involved in cellulose biosynthesis, curli production, fimbriae biosynthesis, flagellar assemble, quorum sensing, chemotaxis, and some transcriptional regulators. Antibiotic efflux conferring antibiotic resistance genes, antibiotic inactivation genes, and antibiotic target alteration genes were also identified. The results expand scientific understanding on how Salmonella isolates with high biofilm-forming capacity and multidrug resistance survive in stressful conditions in the industry.

Bone marrow biopsy (BMB) examination is the gold standard for staging of lymphoma which is interpreted along with other clinical, laboratory and radiological investigations. This study aimed to evaluate the various patterns of BMB infiltration by lymphomas which include Hodgkin and Non Hodgkin lymphoma and the usefulness of BMB compared to bone marrow aspiration (BMA). : In a period of three years, there were 212 cases which showed lymphoma infiltration in bone marrow. We assessed the peripheral blood smear (PBS), BMA and BMB slides and concordance between each was evaluated. BMB slides were assessed for the pattern of involvement. The most frequent subtype was chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) (21.70%) followed by Hodgkin lymphoma (HL)(12.73%)and follicular lymphoma (FL)(11.32%). Predominant pattern of infiltration showed by CLL/SLL cases was mixed pattern, by FL was paratrabecular pattern, mantle cell lymphoma(MCL) showed either diffuse or nodular, diffuse large B cell lymphoma (DLBCL) and Burkitt lymphoma(BL) showed predominantly diffuse pattern. Hairy cell leukemia (HCL) and peripheral T cell lymphoma (PTCL) showed an interstitial pattern. In HL, the pattern was usually focal nodular however diffuse involvement was seen in a few. Of the 212 cases, 50.94% cases had atypical lymphocytes or lymphocytosis in PBS and 81.14% cases showed infiltration in BMA. Atypical lymphoid cells may not be present at times in peripheral blood or bone marrow aspirate in spite of infiltration in the bone marrow. Different lymphomas show characteristic patterns of marrow involvement.

Breast cancer is the most common malignancy in women, accounting for 14 % of all cancers in India; it accounts for &#60; 1% of all cancer cases in men. Breast cancer is the leading cause of death worldwide. The study aims to assess the expression of p53 and Survivin in Fibroadenoma and Invasive carcinoma of no special type and its prognostic importance.A total number of 75 cases are included in the study, out of which 34 are reported by two histopathologists as invasive carcinoma NST (ductal) and 41 reported as Fibroadenoma. All the cases included in the study are females. Immunohistochemistry for p53 and Survivin performed in both the groups with positive and negative controls. Cytoplasmic or nuclear IHC expression for Survivin is considered to be positive. Whereas, nuclear positivity is considered for p53. A semi quantitative scoring system performed consisting of intensity and % of positive cells. The expression of Survivin and p53 is found to be high in IDC, 79% and 85% respectively. The correlation is found to be significant (p value = 0.002, Spearman Rho correlation). However, the expression of Survivin is seen in one third of all the cases of Fibroadenoma (37.5%) and p53 expression is expectedly low, seen in 12% cases. Over expression of Survivin in IDC patients compared to benign cases is found to be correlated with p53 expression. Though Survivin is likely to contribute to apoptosis resistance, its expression is found to confer resistance to chemotherapy and radiotherapy in IDC. Henceforth, Survivin over expression along with p53 in invasive breast carcinoma defining overall poor prognosis and low survival rates.

The human appendix is a supposedly funtionless organ, but can cause morbidity and mortality because it is likely to be infected. Acute Appendicitis being the most common surgical emergency. Appendicectomy specimens from suspected acute appendicitis often appear macroscopically normal but histological analysis reveal a more sinister underlying pathology.A three year study was performed to determine the incidence of various non-neoplastic and neoplastic lesions of appendix. To study the histopathology of various lesions of appendix.It is a retrospective study for a period of three years at Tertiary care hospital. The histopathological reports and clinical details were collected and slides were reviewed and evaluated. Special stains were used wherever required.The study included 1092 cases of lesions of appendix. The commonest lesion was chronic non-specific appendicitis (48.27%) followed by acute appendicitis with (47.80%). Other non neoplastic lesions found were fibrous obliteration of appendix (2.10%), chronic appendicitis with Enterobius vermicularis infestation (0.83), tuberculosis (0.18), xanthogranulomatous appendicitis (0.09%) and amoebic appendicitis (0.09%). Neoplastic lesions seen were low grade mucinous neoplasm (0.18) and serrated adenoma (0.09). Chronic non-specific appendicitis is the commonest appendiceal lesion. The various lesions of appendix clinically present as acute or chronic appendicitis but histology reveals the true nature of the lesion and hence remains the gold standard method.

: Actinomycosis of the oral cavity is not common, though actinomyces species often occur as normal commensals in the oral cavity. They gain entry into deep tissue to cause infection and consequent tissue damage whenever there is damage to the oral mucosa by injury or infection or neoplastic process. The case being discussed here is of a male, aged 62 years, who presented with an ulcero-proliferative lesion over left buccal mucosa. A punch biopsy was carried out on the lesion. Histopathology laboratory received three gray-white tissue pieces. Histological examination of the tissue pieces revealed features of moderately to poorly differentiated squamous cell carcinoma. Few colonies of radiating filamentous structures reminiscent of colonies of actinomyces species were noted. The sections were further stained with relevant stains for filamentous bacteria such as Periodic Acid Schiff (PAS) stain which confirmed the colonies of Actinomyces spp. The case being submitted here is an unique and relatively rare finding of concomitant squamous cell carcinoma and oral actinomycosis with only few cases being reported in publish English medical literature.
Hibernoma-A rare tumor on rare site
Authors: Mishra Himachal , Alexander Manika 
Published: January 2023

Hibernoma is a rare benign tumor that originates from brown fat. Hibernoma is thought to arise from areas containing residual brown fat like- the interscapular area, axilla, neck, chest, abdominal cavity, and retroperitoneum. The incidence of this rare tumor has very rarely been reported to occur over the forehead. Being a benign tumor, no association of malignant transformation or metastasis has been reported. A 23-year-old male presented with a complaint of a painless non-progressive swelling over the forehead for the past 6 months. On examination, the swelling was 2x2 cm, soft, mobile, non-tender, and non-pulsatile with no skin changes. FNAC did which shows sheets and clusters of adipocytes with abundant foamy cytoplasm and reported as “Hibernoma”. The patient has been asked to follow up and for the last 1 year, the tumor is still non-progressive with no pressure symptoms and hence has not undergone surgery. Hibernoma is a rare benign tumor of brown fat tissue which constitutes only 1.6% of benign lipomatous tumors but their actual prevalence is still unknown. This tumor very rarely may occur in the forehead area although incidence over the forehead has rarely been reported. Since this tumor is slow growing, painless non-progressive; it mostly presents as an asymptomatic tumor. It has to be included in the differential diagnosis of adipocyte-containing tumors to prevent false treatment.
An overview of classical ottoman art of fabric

Published: January 2023

Seljuk Turks who began to settle in Anatolia since 11th century showed a great improvement in this area by combining the weaving tradition that they carried from Central Asia, Transoxiana, Khwarezm and Iran with the savings in Anatolia (Ãœlgen, 1996). Turkish fabrics began to get their most characteristic motifs and a thin and a perfect weaving technique just to the end of 15th century. Reaching its highest level in 16thcentury, our fabric weaving technique improved after such a long development cycle (SÃ¼slÃ¼, 1976).All the arts had their golden age during the classical Ottoman Period. It is also the most magnificent age for 16th century Turkish fabric art. It has been effective in the selection of topic that fabrics wear out in time and design schemas on them face the danger of evanescence because of their raw materials.In this research, relevant resources have been searched and fabric figure drawings were drawn by taking photos from the museums that have classical Ottoman Period fabrics. The weaving centers, raw materials, colors and figures of classical Ottoman Period fabrics have been established and has set out the importance of the Classical Ottoman fabric art.

Published: January 2023

Over the years, art in its various forms has played a vital role in the lives of African people. It served as a major form of communicative expression of religious beliefs and socio-cultural norms of the people. Its form, presentation and significance however, varied from one cultural setting to another. This paper examines art in the context of domestic architecture of indigenous people of South West Nigeria and its relevance in contemporary housing as well as what it portends for architectural education in that cultural zone. The paper notes the disappearance of the rich traditional motifs and symbols from contemporary housing and their replacement with more contemporary art forms influenced by globalisation and industrial mass production. It concludes that the current trend presents an architecture that is devoid of cultural architectural uniqueness and identity. One of the implications identified is for architectural curricula to incorporate indigenous themes that will help architects produce domestic architecture that have contextual relevance. Data for the paper was collected through literature review and the qualitative research method using interviews and observations of houses in the zone. Those interviewed include architects and residents in the zone. Data was content analysed to highlight common themes.Keywords: Art, Domestic architecture, YorubalandÂ Â
