Abstract
In this paper, we report the outcomes when fluorescence material coated the hollow core (inner part) of D-shaped photonic crystal fiber (PCF) that has internal diameter (ID), 10 μm. Fluorescence involves the emission of light by a substance that has absorbed light or other electromagnetic radiation. The coated material namely, allene has contributed significantly to the output of transmission spectra at the visible region. The changes in transmission wavelength are remarked when certain parameters vary along the study. The air hole deposited with allene exhibits strong electromagnetic interaction which is good for optical absorption and hence could promote high-sensitivity performance. The optimum condition on how allene covered the hollow PCF which this includes the number of days dipping leads to the bigger wavelength shifting comparing to its emission at 530 nm. Therefore, this study report that allene material could promote an important role in sensing applications at the visible as it displays a good response.
Investigation of microstructure and texture as related to primary recrystallization of grain-oriented silicon steel
Authors: Gong Jian , Godfrey Andrew , Ma Jiaji , Li Ruifeng 
Published: November 2023

Abstract
Grain-oriented silicon steel requires a very strong Goss {110}<001> texture and as such a comprehensive control of thermo-mechanical processing parameters is required to achieve a strict control of texture. In particular the cold rolling and decarburization annealing process parameters have a determining effect on the grain size, the grain size distribution and the crystal texture distribution. In this study, the effect of cold rolling reduction on texture distribution in cold-rolled sheet has been analyzed. Secondary recrystallization of grain-oriented silicon steel is also highly dependent on the microstructure and texture after primary recrystallization. The influence of annealing temperature and carbides on the primary recrystallization process has also been investigated by measurements of grain growth and texture following primary recrystallization. By optimizing the microstructure and the texture of primary recrystallization of grain-oriented silicon steel, it is shown that a grain-oriented silicon steel exhibiting high magnetic induction low iron loss has been developed at Shougang Steel.
Study on the recrystallization microstructure and texture evolution of a rolled 0.075 mm ultra-thin grain-oriented silicon steel

Abstract
This paper investigated the recrystallization behavior of a rolled 0.075 mm ultra-thin grain-oriented silicon steel, and microstructure and texture evolutions were studied. At the early stage, dominant {hk0}<001> recrystallized grains were ascribed to the preferential {hk0}<001> nucleation, then their growth was reduced by texture pinning effect. In contrast, a few ‘random’ grains grew excessively to consume surrounding {hk0}<001> fine-grained matrix, meanwhile nuclei originating from initial non-Goss grains also showed size advantage and further grew. Despite of quasi-two-dimensional microstructure of ultra-thin sheet, the anisotropic surface energy did not show marked effect on grain growth difference. Those coarse grains, which were 10 times larger than the matrix grains, were surrounded by high energy (HE) boundaries, indicating that their growth was driven by high grain boundary mobility. With the increasing annealing time, the formation of {hk0}<001> oriented assemblies and the growth of non-{hk0}<001> oriented grains contributed to the overall grain size increase. Regarding the relationship between microstructure, texture and magnetic properties, {hk0}<001> texture was weakened and reduced magnetic induction accordingly, and the combination of growing while heterogeneous grain size and changing texture made iron loss a first decrease and then increase tendency. It is essential to control annealing time to obtain suitable combination of microstructure and texture.
The effect of layer interface on recrystallization behavior of layered aluminum: An in-situ EBSD study

Published: November 2023

Abstract
In recent years, layered heterogeneous metallic materials have received considerable attention. In this work, we fabricated an AA3003/AA1060 layered aluminum and introduced heterogeneity by regulating recrystallization behavior via accumulative roll bonding and annealing processes. The annealing process was studied by in-situ electron backscatter diffraction (EBSD) observation. The present work shows that the recrystallization rate in the AA1060 layer is significantly higher than that in the AA3003 layer. This disparity can be attributed to the varying element composition, which generates a layered aluminum structure comprising alternating fine-grained and coarse-grained layers. Moreover, the influence of layer interface on the recrystallization behavior of the AA1060 layer was investigated. The result shows that high energy storage near the interface promotes recrystallization nucleation and grain growth. This study reveals the formation mechanism of layered heterogeneous metallic materials, which can help the design and preparation of high-performance heterogeneous metallic materials.

Abstract
Cr-Ni-Mo steel, as a hot-work die steel, has become increasingly demanding of service temperature and strength. This study investigated the effect of precipitates on the deformation behavior of tempered martensite at 700 °C. Tempering specimens with different dislocation densities leads to different behavior due to the size and volume fraction of precipitates. This decreases dynamic recrystallization and interfacial mobility, resulting in higher interfacial energy. Meanwhile, the precipitates boost strength and thermal stability of the tempered martensite.

Published: November 2023

Abstract
The competing mechanisms of ferrite nucleation on (Ti,V)(C,N) MX carbonitrides and dislocations, as well as their dependence on deformation, are investigated experimentally by thermo-mechanical treatments and via simulation. The impact of recrystallization and the resulting austenite grain size on intragranular ferrite nucleation is evaluated. The austenite-to-ferrite transformation temperatures, affected by different microstructures, are examined by isothermal uniaxial single-hit compression tests on a dilatometer DIL 805 and compared to thermal treatments without deformation. Different resulting microstructures are analyzed by using optical light microscopy. The experimental data is used for the validation of thermo-kinetic simulations with the mean-field modeling software MatCalc using the implemented models for the austenite grain evolution, the on-particle nucleation of ferrite on the surface of MX particles, the dislocation density evolution, and recrystallization.
Event Detection with Word-Word Relation Classification
Authors: Shen Yatian , Han Yiru , Yang Huijing , Wang Songyang , Lu Chengeng 
Published: November 2023

Abstract
Event detection (ED) is a critical task in information extraction, aiming to identify triggers and types. Current research has increasingly focused on fine-grained types, where a single sentence may contain multiple trigger words and event types. Previous models only considered sentence-level features, neglecting word-word features and word positional information in the text. We propose a novel labeling scheme that treats event detection as a word-word relation recognition task. In this approach, we first identify relationships between word pairs and then utilize these relationships to perform trigger and event-type detection. By adopting this method, we can efficiently and concurrently identify triggers and types in a sentence. Leveraging word pair relationships effectively addresses scenarios in which multiple trigger words appear in a single sentence. The results demonstrate that our approach outperforms several baseline models.
Image Water Ripple Detection Method Based on Constraint Convolution and Attention Mechanism

Published: November 2023

Abstract
Noise can introduce irrelevant interference signals, reduce the signal-to-noise ratio of the image, weaken the contrast between the target and the background, and make it more difficult to detect the target in the image, thus increasing the difficulty of water ripple detection. Therefore, a method for image water ripple detection based on constraint convolution and attention mechanism is proposed. Using the attention mechanism for image denoising, the “attention map” is calculated from both channel and spatial aspects, and the calculated “attention map” is multiplied by the image feature map for adaptive feature learning to achieve image denoising processing. The convolutional neural network is used to extract the features of the input image. Based on feature extraction, the constrained convolution operation is applied to highlight the detailed features of water ripples. The features obtained from the constrained convolution operation are input into the support vector machine classifier for the classification and detection of water ripples. According to the relationship between the patterns and features learned by the classifier, whether the image belongs to the category of water ripples is judged, to achieve water ripple detection. The experimental results show that the proposed method has a good image denoising effect and water ripple detection effect.

Abstract
This study investigates the sensitivity of the boreal winter prediction skill of Community Atmosphere Model 5 to the choice of the dynamical core. Both finite volume (FV) and spectral element (SE) dynamical cores are tested. An additional FV with the SE topography (FVSE) is also conducted to isolate the possible influence of the topography. The three dynamical core experiments, which ran from 2001/2002–2017/2018, are validated using Japanese 55 year reanalysis data. It turns out that the SE (−4.27 °C) has a smaller cold bias in boreal-winter surface air temperature (SAT) than the FV (−5.17 °C) and FVSE (−5.29 °C), particularly in North America, East Asia, and Southern Europe/Northern Africa. Significant North Atlantic Oscillation-like biases are also identified in the mid-troposphere. These biases affect seasonal prediction skills. Although the overall prediction skills of boreal-winter SAT, quantified by the anomaly correlation coefficient (ACC), and root-mean-square error (RMSE), are reasonably good (ACC = 0.40 and RMSE = 0.47 in the mean values of SE, FV, and FVSE), they significantly differ from one region to another, depending on the choice of dynamical cores. For North America and Southern Europe/Northern Africa, SE shows better skills than FVSE and FV. Conversely, in East Asia, FV and FVSE outperform SE. These results suggest that the appropriate choice of the dynamical cores and the bottom boundary conditions could improve the boreal-winter seasonal prediction on a regional scale.

Abstract
Air pollutants have a significant impact on humans and the environment, making their reduction and mitigation crucial and requiring attention from policymakers. In this study, the impact of air pollutant concentrations, namely particulate matter with an aerodynamic diameter less than 10 μm (PM10), particulate matter with an aerodynamic diameter less than 2.5 μm (PM2.5), sulphur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3) and carbon monoxide (CO) on the environmental performance of 15 states in Malaysia was examined using available data from 2018 to 2021. The analysis was performed using data envelopment analysis (DEA) with slack-based measure (SBM) and the Malmquist productivity index (MPI). The efficiency values were used for principal component analysis (PCA) to infer the influencing factors that are highly redundant or dependent on each other. Results from SBM-DEA suggested an important aspect of gross domestic product toward efficiency score, where high efficiency values were observed for Selangor, Kuala Lumpur, and a small state like Perlis (efficiency value of 1.000). The MPI score indicated that the performance of each state was relatively low for the years 2019–2020, which suggested a regression in performance productivity due to the haze episode. PCA analysis showed that there were two factors, where the highest contribution for Factor 1 was Melaka and Johor with an average contribution of 8.15% and for Factor 2 was Perlis and Perak with an average contribution of 23%. This study’s findings showed that air pollutants play significant roles in achieving good environmental performance in order to tackle global issues such as global warming and climate change.
Local well-posedness and singularity formation in non-Newtonian compressible fluids
Authors: Lerman Ariel , Disconzi Marcelo M , Noronha Jorge 
Published: November 2023

AbstractWe investigate the initial value problem of a very general class of3+1non-Newtonian compressible fluids in which the viscous stress tensor with shear and bulk viscosity relaxes to its Navier–Stokes values. These fluids correspond to the non-relativistic limit of well-known Israel–Stewart-like theories used in the relativistic fluid dynamic simulations of high-energy nuclear and astrophysical systems. After establishing the local well-posedness of the Cauchy problem, we show for the first time in the literature that there exists a large class of initial data for which the corresponding evolution breaks down in finite time due to the formation of singularities. This implies that a large class of non-Newtonian fluids do not have finite solutions defined at all times.

Published: November 2023

Abstract
Following International Maritime Organization (IMO) policy directives, the maritime industry has been seeking efficient solutions to alter the energy consumption patterns of ports and ships to ensure the sustainable operation and reduce greenhouse gas emissions to support sustainable transport. However, there is little focus on identifying the energy consumption and greenhouse gas emissions related ship manufacture. The shipyard industry can generate greenhouse gas effects from burning fossil fuels and energy use. This study aims to identify the amount of greenhouse gas emissions produced in the shipyard industry. The first step to calculating the number of greenhouse gas emissions is to start by identifying the sources of CO2 emissions, then calculate the emissions by the calculations referred to IPCC 2006. Based on the research results, total primary and secondary CO2 emissions in the shipyard is 358,693,723 tons CO2/year.

Abstract
Green, selective and accurate high-performance liquid chromatography (HPLC) chromatographic method is presented for simultaneous separation and quantitation of the co-prescribed drugs in chemotherapy omeprazole, ondansetron and deflazacort in spiked human plasma. An isocratic HPLC separation was performed on X Bridge C18 (4.6 × 250 mm) column with 5 μm particle size using mobile phase consisting of methanol: ammonium acetate buffer pH 4 adjusted by acetic acid (60: 40, v/v). The injection volume was 20μL with UV detection wavelength at 237 nm at room temperature. Flow rate of the mobile phase was adjusted to be 2.0 ml/min. Dexamethasone was used as internal standard to correct the variation during sample pretreatment. FDA guidelines were followed to validate the developed method. Successful application of the developed method was revealed by simultaneous determination of omeprazole, ondansetron and deflazacort in spiked human plasma in ranges of 1–20, 0.1–8 and 0.2–8 μg mL−1 for omeprazole, ondansetron and deflazacort, respectively. Four greenness assessment tools were used to evaluate the greenness of the developed method and the results were accepted. This method permitted the accurate simultaneous determination of the studied drugs, thus it can be used during therapeutic drug monitoring in daily clinical practice.

Abstract

Background
Long-term outcomes of tenofovir-containing antiretroviral therapy (ART) for hepatitis B virus (HBV)/human immunodeficiency virus (HIV) coinfection were evaluated in Zambia.

Methods
A prospective cohort of adults with HIV and hepatitis B surface antigen (HBsAg)-positivity was enrolled at ART initiation. On tenofovir-containing ART, we ascertained HBV viral load (VL) non-suppression, alanine aminotransferase (ALT) elevation, serologic end-points, progression of liver fibrosis based on elastography, and hepatocellular carcinoma (HCC) incidence. We also described a subgroup (low HBV VL and no/minimal fibrosis at baseline) that, under current international guidelines, would not have been treated in the absence of their HIV infection.

Results
Among 289 participants at ART start, median age was 34 years, 40.1% were women, median CD4 count was 191 cells/mm3, 44.2% were hepatitis B e antigen-positive, and 28.4% had liver fibrosis/cirrhosis. Over median 5.91 years of ART, 13.6% developed HBV viral non-suppression, which was associated with advanced HIV disease. ALT elevation on ART was linked with HBV VL non-suppression. Regression of fibrosis and cirrhosis were common, progression to cirrhosis was absent, and no cases of HCC were ascertained. HBsAg seroclearance was 9.4% at 2 and 15.4% at 5 years, with higher rates among patients with low baseline HBV replication markers.

Conclusions
Reassuring long-term liver outcomes were ascertained during tenofovir-based ART for HBV/HIV coinfection in Zambia. Higher than expected HBsAg seroclearance during ART underscores the need to include people with HIV in HBV cure research.
Witnessing the Suffering of Others in Watercolor and Pencil: Jadwiga Simon-Pietkiewicz’s Holocaust Art Exhibited in Sweden, 1945–46
Authors: Martínez Victoria Van Orden 
Published: November 2023

Abstract
In the Holocaust’s immediate aftermath (1945–1946), a small gallery in Lund, Sweden exhibited the paintings and drawings of Polish artist Jadwiga Simon-Pietkiewicz, which depicted her former fellow inmates in the Ravensbrück concentration camp. This exhibit and subsequent exhibitions elsewhere in Sweden marked rare instances of early postwar Holocaust art displayed in a country that had been relatively unaffected by the Holocaust. By analyzing the response of the Swedish public and press to the artwork in these exhibits, as well as Swedish and international responses to “atrocity photos” of the liberation, the author broadens our understanding of Holocaust art, early testimonies, and agency and resistance during and after the Holocaust.

Abstract

Background
This study aimed to define clusters of disease activity and prognostic factors of disease course in a well-characterized cohort of children with Crohn’s disease (CD).

Methods
All patients from the SIGENP IBD (Italian Society of Pediatric Gastroenterology Hepatology and Nutrition Inflammatory Bowel Disease) registry with a 5-year follow-up and 6-monthly evaluation were included. Active disease was defined for each semester as follows: clinical activity (weighted Pediatric Crohn’s Disease Activity Index ≥12.5 or Mucosal Inflammation Noninvasive Index ≥8) and active disease on endoscopy (Simple Endoscopic Score for Crohn’s Disease &gt;3 or fecal calprotectin &gt;250 µg/g) or imaging. Formula-based clusters were generated based on previously published patterns in adults.

Results
Data from 332 patients were analyzed. A total of 105 (32%) experienced a quiescent disease course; 49 (15%) and 31 (9%) a moderate-to-severe chronically active and chronic intermittent disease, respectively; 104 (31%) and 43 (13%) had active disease in the first 2 years after diagnosis and remission thereafter and vice versa, respectively. Surgery at diagnosis was significantly associated with a quiescent course (odds ratio [OR], 10.05; 95% confidence interval [CI], 3.05-25.22; P=.0005), while growth impairment at the diagnosis and active disease requiring corticosteroids at 6 months were inversely related to the quiescent group (OR, 0.48; 95% CI, 0.27-0.81; P= .007; and OR, 0.35; 95% CI, 0.16-0.71; P= .005, respectively). Perianal involvement at diagnosis and moderate–severe activity at 6 months correlated with disease progression (OR, 3.85; 95% CI, 1.20-12.85; P=.02).

Conclusions
During the first 5 years of follow-up, one-third of children with CD experience a quiescent course. However, another one-third have a moderate-to-severe disease course. Surgery at the diagnosis is related to a quiescent course, while growth impairment and lack of response to induction therapy correlate with more severe disease activity during follow-up.
