Target intensity correction method based on incidence angle and distance for a pulsed Lidar system
Authors: Qi Baoling , Yang Guohui , Zhang Yu , Wang Chunhui 
Published: February 2024

Pulsed light detecting and ranging (Lidar) is capable of acquiring comprehensive target information within a single pulse, including distance and intensity data. Intensity data reflects the target’s backscattered intensity and is commonly regarded as a crucial observational parameter associated with target reflectivity information. Multiple studies have indicated the potential of intensity data in various applications within pulsed Lidar contexts. However, the intensity data is influenced by the incident angle and distance; hence it cannot directly manifest target characteristics. Consequently, a prerequisite for its usage is the implementation of intensity calibration. This paper presents a target intensity correction method based on an improved tail model, designed for preprocessing intensity data. First, the pulse echo signal equation is derived by incorporating the improved tail model with the detected target. On this foundation, a target echo intensity correction model is established to correct the intensities at various incident angles to those at the normal direction. Lastly, the derived approach is validated through simulation analysis, and practical experiments are conducted on a constructed pulsed Lidar system. These experiments meticulously investigate the influences of incident angle and distance, two prominent factors, on echo intensity. In the context of incident angle correction experiments, the mean absolute errors (MAEs) in calibrated values for diverse targets all remain within 0.04 V. Prior to correction, the maximum MAE for the cystosepiment is 0.505 V; after the correction it is reduced to merely 0.02 V, indicating a 96% reduction in error. Furthermore, all discrepancies exhibit an error standard deviation (ESD) of 0.03 V or less, showcasing favorable stability. For distance correction, under normal incidence conditions, a diverse set of targets is measured at different distances to achieve corrected MAE and ESD within 0.05 V. Consequently, the proposed method effectively achieves intensity correction concerning incident angles and distances. To achieve this, a reflectivity lookup table for the relevant targets was established. Combining this with the corrected intensity information enabled target identification in the three-dimensional imaging of pulsed Lidar.

Published: February 2024

Background
Multidrug-resistant (MDR) Klebsiella species are among public health important bacteria that cause infections difficult to treat with available antimicrobial agents. Infections with Klebsiella lead to high morbidity and mortality in developing countries particularly in patients admitted to the intensive care unit. This systematic review and meta-analysis aimed to determine the pooled prevalence of MDR Klebsiella species from different human specimens using studies conducted in Ethiopia from 2018−2022.

Methods
We have systematically searched online databases such as PubMed/Medline, Google Scholar, Hinari, African journals online, Web of Science, Cochrane, and grey literature (Addis Ababa University and Hawassa University) to identify studies reporting the proportion of MDR Klebsiella species in Ethiopia. Published articles were selected based on the Preferred Reporting Item of Systematic Review and Meta-analysis (PRISMA). R-Studio version 4.2.3 was used to conduct pooled prevalence, heterogeneity test, and publication bias. A binary random effect model was used to determine the pooled prevalence. Heterogeneity was checked with the inconsistency index (I2). Publication bias was checked with a funnel plot and Egger test. Sensitivity analysis was conducted with leave-one-out analysis. Joanna Briggs Institute’s critical appraisal tool for prevalence studies was used to check the quality of each article.

Results
In this systematic review and meta-analysis, 40 articles were included in which 12,239 human specimens were examined. Out of the total specimens examined, 721 Klebsiella species were isolated and 545 isolates were reported to be MDR Klebsiella species. The prevalence of MDR Klebsiella species ranged from 7.3%-100% whereas the pooled prevalence of MDR Klebsiella species was 72% (95% CI: 63 − 82%, I2 = 95%). Sub-group analysis based on region revealed the highest prevalence of MDR from Addis Ababa (97%) and the least from the Somali region (33%); whereas sub-group analysis based on the specimen type indicated the highest prevalence was from blood culture specimens 96% and the least was from other specimens (ear and vaginal discharge, and stool) (51%).

Conclusion
Our finding indicated a high prevalence of MDR Klebsiella species found in different human specimens. The prevalence of MDR Klebsiella varies across regions in Ethiopia, age, the type of specimens, source and site of infection. Therefore, integrated action should be taken to reduce the prevalence of MDR Klebsiella species in regional states and focus on clinical features. Effective infection and prevention control should be applied to reduce the transmission within and outside health care settings.
"… a vízben kell elmerítenem majd feloldanom a verset" Haiku értelmezés középiskolásoknál

Published: February 2024

Az absztrakt gondolkodás szintje nagymértékben összefügg a tanulmányi eredménnyel. A magas absztrakt gondolkodási szint alapján jó eredmények várhatóak a matematika és a természettudományok területein (Shayer 1999; Nurjannah, Kusnandi 2020). Az absztrakció folyamatát tekintik a számítástechnikai gondolkodás magjának (Zehetmeier et al. 2019). Az absztrakt gondolkodással rendelkező tanulók képesek deduktív és induktív módon gondolkodni, tudják elemezni a lehetőségeket és jól hasznosítják az absztrakt gondolatokat (Velasquez 2013). Magas fokú absztrakcióval jár a szimbólumok értelmezése (Kapitány, Kapitány 2020). Szepes (2014) úgy véli, hogy a haiku műfajban írt költeményben a verset éppen szimbolikus képi jellege teszi műfajilag haikuvá, amikor a vers érzékileg észlelhető képi síkja mögött meghúzódik egy átvitt, gondolati sík is.
Kutatásunkban az absztrakt gondolkodást vizsgáljuk középiskolás fiatalok haiku értelmezései alapján. Fodor Ákos Elkészítési javaslat című, haiku műfajban írt költeményében a víz szimbólumának értelmezését elemezzük három szegedi gimnáziumban tanuló 449 középiskolás válasza nyomán. Vizsgálatunkat a témában végzett, a KAPOCS Kutatócsoport 2022-es olvasáskutatásának adatai alapján végezzük el.
Kutatásunkban arra keressük a választ, hogy a középiskolás tanulók milyen típusú és mennyiségű elvont fogalmat használtak a víz szimbólumának az értelmezésénél? Az elvont fogalmak használatának gyakorisága kapcsolatban van-e könyvolvasási szokásaikkal?

INTRODUCTION:
Underutilization of hepatocellular cancer (HCC) surveillance has been reported, although data evaluating interventions to improve surveillance are sparse. We assessed the effect of a population-based HCC surveillance program on HCC surveillance utilization and outcomes.

METHODS:
In this retrospective cohort study, we assessed preinclusion and postinclusion HCC surveillance patterns among 597 patients with hepatitis C virus cirrhosis enrolled in a program at an integrated health system between 2013 and 2020. Adequate surveillance was defined as at least 5 surveillance studies within 36 months pre-enrollment and postenrollment; a secondary outcome was proportion of time covered by surveillance over 36 months. Tumor size, stage, and receipt of curative therapy were compared between HCC detected on the first imaging examination (prevalent HCC) and surveillance-detected HCC (incident HCC). We performed Kaplan-Meier analysis and multivariable competing risk analysis to characterize the association between surveillance and mortality.

RESULTS:
The surveillance program significantly improved surveillance completion (77.6% vs 5.0%, P < 0.001) and proportion time covered (80.9% vs 15.8%, P < 0.001). Compared with prevalent HCC, surveillance-detected cases were more likely unifocal (77.8% vs 44.8%, P < 0.001), early-stage (85.2% vs 44.8%, P < 0.001), with smaller maximum diameter (median 2.3 vs 3.2 cm), and more likely to undergo curative therapy (92.5% vs 72.4% P = 0.010). Survival was improved compared with prevalent cases hazard ratio (HR) 0.23 (0.11–0.51) after adjusting for age and Model for End Stage Liver Disease score.

DISCUSSION:
Implementation of a population-based program resulted in significant improvement in HCC surveillance use and clinical outcomes among patients with hepatitis C virus cirrhosis. These findings may inform similar interventions by other healthcare systems.
Numerical study on discharge capacity of piano key side weir with various ratios of the crest length to the width
Authors: Alabedi Hiba Jameel , Khassaf Saleh Issa 
Published: February 2024

Abstract
A side or lateral weir can be defined as a longitudinal weir put in parallel to the main flow direction. A piano key side weir (PKSW) is one of the various side weirs used to control flow level, flow diversion, and flood harm prevention in dams and hydraulic systems. A side weir aims to keep the water level in the main channel at a specific level by discharging the overflow water into a side channel. The discharge coefficient of the PKSW was covered in this study by numerical modeling of a rectangular PKSW type B with various ratios of the crest length to the width in a straight channel. Results showed that the discharge coefficient of the PKSW was more affected by the L/W parameter when the other parameters were constant. It was noted that the PKSW discharge coefficient for L/W equal to 6 demonstrated a significantly higher level of performance and also found that increasing the upstream head above the side weir crest (h
a/P) negatively affected the coefficient of discharge. It was concluded that a high capacity of the discharge coefficient required the (h
a/P) ratio to be smaller than 0.75 or within the range (0.3 ≤ h
a/P < 0.75).
Indexical meanings of the realization of /sˤ/ ص as [s] س in spoken and written Jordanian Arabic: a language change in progress?
Authors: Zibin Aseel , Daoud Sumaya , Mitib Altakhaineh Abdel Rahman 
Published: February 2024

Abstract
This study examines how the phonetic realisation of the phoneme /sˤ/ and its orthographic form ص is surfacing as the variant [s] in speaking and as س in writing in Ammani Arabic (AA), which is a variety of Jordanian Arabic (JA), and how this relates to language variation. We look at instances where certain Ammani Arabic speakers, particularly females, pronounce and write words containing /sˤ/ ص as [s] س, despite both /sˤ/ and /s/ being phonemes in JA in general and in AA in particular. We used a quantitative corpus-based approach, where we obtained written data from Facebook, and elicited spoken tokens and qualitative data through interviews. Our findings reveal that females in our two corpora [spoken and written] use and prefer [s] and س more than males, and our interviews revealed that female interviewees also prefer this pronunciation and writing. We suggest that the use of [s] س instead of [sˤ] ص by females can be seen as a direct index for femininity within their community of practice, and that this pronunciation/writing can indirectly index female gender in daily conversations and on social media websites, based on orders of indexicality (Silverstein, Michael. 2003. Indexical order and the dialectics of sociolinguistic life. Language & Communication 23. 193–229).

Authors: Song Chunyan , Li Mo , Zhang Weidong , Wu Xiaodong , Gao Song 
Published: February 2024

Abstract
Based on the theory of coplanar waveguide (CPW) transmission line, a novel microwave non-destructive strain monitoring sensor specifically designed for cement-based material structures is presented in this study. The aim is to establish the relationship between the variation of the S11 phase parameter of the CPW strain sensor and the structural strain, utilizing a linear analysis. The feasibility of the strain monitoring by the CPW sensor is validated through simulations and experiments. The obtained results demonstrate a strong linear correlation between the phase change of the S11 parameter and the strain, with a goodness of fit of 0.987. The simulated strain sensor exhibits a sensitivity of 48.83 ppm/με, while the experimental measurement sensor shows a sensitivity of 65.82 ppm/με. These findings highlight the potential significance of the proposed method, offering a new approach that is characterized by high sensitivity, low cost, and simplicity for strain monitoring in concrete structures. Among them, the sensor cement mortar matrix made in this study was mixed with the recycled material made of waste glass steel FRP after a certain treatment process. The development of this method holds promise for the advancement of health monitoring in concrete structures.
Best practices and future challenges in the treatment of oral cancer
Authors: Kröplin Juliane , Reppenhagen Jil-Charlot 
Published: February 2024

Abstract

Objectives
Oral cancer is among the most common tumour worldwide. Due to the anatomical peculiarities of the head and neck region, the treatment of oral cancer is a major challenge with regard to the preservation of aesthetics and function. The aim of the present study is to analyze currently practiced therapeutic strategies as well as current and future challenges in the therapy of oral cancer.

Methods
A Pubmed-based selective literature search was performed considering literature predominantly from 2021 to 2022. Search terms were “oral cancer,” “oral cavity cancer,” and “head and neck cancer.”

Results
Head and neck tumours are the seventh most common cancer worldwide. The suspected diagnosis of oral cancer is often made by outpatient dentists during routine examinations. With the outbreak of the 2020 COVID 19 pandemic, risk behaviour has changed with regard to the development and diagnosis of oral cancer. The gold standard of therapy is surgical resection. The need for adjuvant therapy measures depends on the histopathological TNM stage and other defined risk factors. Recurrences occur frequently and should be evaluated with regard to renewed surgical therapy. Future treatment strategies are aimed at early diagnosis, precision in resection, the use of digital technologies, and aspects of quality assurance. The economic importance in the treatment of oral cancer is currently given little consideration.

Conclusions
The study presents a selective portfolio of treatment strategies currently practiced in Germany and in many parts of the world. In addition, future challenges in the therapy of oral cancer, in particular squamosa cell carcinoma, are presented.

Use of person-centered language in obesity-related publications across sports medicine journals: a systematic review of adherence to person-centered language guidelines in sports medicine
Authors: Webb Jason , Mach Kaylee , Gooch Trey , Reddy Arjun , Anderson Michael , Scott Jeremy , Checketts Jake , Walker Lance , Hartwell Micah 
Published: February 2024

Abstract

Context
Stigmatizing language or non-person-centered language (non-PCL) has been shown to impact patients negatively, especially in the case of obesity. This has led many associations, such as the American Medical Association (AMA) and the International Committee of Medical Journal Editors (ICMJE), to enact guidelines prohibiting the use of stigmatizing language in medical research. In 2018, the AMA adopted person-centered language (PCL) guidelines, including a specific obesity amendment to which all researchers should adhere. However, little research has been conducted to determine if these guidelines are being followed.

Objectives
Our primary objective was to determine if PCL guidelines specific to obesity have been properly followed in the sports medicine journals that are interacted with most frequently.

Methods
We searched within PubMed for obesity-related articles between 2019 and 2022 published in the top 10 most-interacted sports medicine journals based on Google Metrics data. A predetermined list of stigmatizing and non-PCL terms/language was searched within each article.

Results
A total of 198 articles were sampled, of which 58.6 % were found to be not compliant with PCL guidelines. The most common non-PCL terms were “obese” utilized in 49.5 % of articles, followed by “overweight” as the next most common stigmatizing term at 40.4 %. Stigmatizing labels such as “heavy, heavier, heaviness,” “fat” as an adjective, and “morbid” appeared in articles but at a lower rate.

Conclusions
Our study shows that there is a severe lack of adherence to PCL guidelines in the most-interacted sports medicine journals. Negative associations between stigmatizing language and individuals with obesity will only persist if a greater effort is not made to change this. All journals, including the most prestigious ones, should adopt and execute PCL guidelines to prevent the spread of demeaning language in the medical community.
Machine-learning-based prediction of a diagnostic model using autophagy-related genes based on RNA sequencing for patients with papillary thyroid carcinoma
Authors: Chen Lin , Tao Gaofeng , Yang Mei 
Published: February 2024

Abstract
Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer and belongs to the category of malignant tumors of the thyroid gland. Autophagy plays an important role in PTC. The purpose of this study is to develop a novel diagnostic model using autophagy-related genes (ARGs) in patients. In this study, RNA sequencing data of PTC samples and normal samples were obtained from GSE33630 and GSE29265. Then, we analyzed GSE33630 datasets and identified 127 DE-ARGs. Functional enrichment analysis suggested that 127 DE-ARGs were mainly enriched in pathways in cancer, protein processing in endoplasmic reticulum, toll-like receptor pathway, MAPK pathway, apoptosis, neurotrophin signaling pathway, and regulation of autophagy. Subsequently, CALCOCO2, DAPK1, and RAC1 among the 127 DE-ARGs were identified as diagnostic genes by support vector machine recursive feature elimination and least absolute shrinkage and selection operator algorithms. Then, we developed a novel diagnostic model using CALCOCO2, DAPK1, and RAC1 and its diagnostic value was confirmed in GSE29265 and our cohorts. Importantly, CALCOCO2 may be a critical regulator involved in immune microenvironment because its expression was related to many types of immune cells. Overall, we developed a novel diagnostic model using CALCOCO2, DAPK1, and RAC1 which can be used as diagnostic markers of PTC.

Published: February 2024

Abstract
Hybridisation of the cavity modes and the excitons to polariton states together with the coupling to the vibrational modes determine the linear optical properties of organic semiconductors in microcavities. In this article we compute the refractive index for such system using the Holstein–Tavis–Cummings model and determine then the linear optical properties using the transfer matrix method. We first extract the parameters for the exciton in our model from fitting to experimentally measured absorption of a 2,7-bis[9,9-di(4-methylphenyl)-fluoren-2-yl]-9,9-di(4-methylphenyl) fluorene (TDAF) molecular thin film. Then we compute the reflectivity of such a thin film in a metal clad microcavity system by including the dispersive microcavity mode to the model. We compute susceptibility of the model systems evolving just a single state vector by using the non-Markovian quantum state diffusion. The computed location and height of the lower and upper polaritons agree with the experiment within the estimated errorbars for small angles

Published: February 2024

Abstract
Literature reports have demonstrated that Schiff-base-type ligands can serve as robust platforms for the synthesis of heterobimetallic complexes containing transition metals and the uranyl dication (UO2
2+). However, efforts have not advanced to include either synthesis of complexes containing second- or third-row transition metals or measurement of the redox properties of the corresponding heterobimetallic complexes, despite the significance of actinide redox in studies of nuclear fuel reprocessing and separations. Here, metalloligands denoted [Ni], [Pd], and [Pt] that contain the corresponding Group 10 metals have been prepared and a synthetic strategy to access species incorporating the uranyl ion (UO2
2+) has been explored, toward the goal of understanding how the secondary metals could tune uranium-centered redox chemistry. The synthesis and redox characterization of the bimetallic complex [Ni,UO2] was achieved, and factors that appear to govern extension of the chosen synthetic strategy to complexes with Pd and Pt are reported here. Infrared and solid-state structural data from X-ray diffraction analysis of the metalloligands [Pd] and [Pt] show that the metal centers in these complexes adopt the expected square planar geometries, while the structure of the bimetallic [Ni,UO2] reveals that the uranyl moiety influences the coordination environment of Ni(II), including inducement of a puckering of the ligand backbone of the complex in which the phenyl rings fold around the nickel-containing core in an umbrella-shaped fashion. Cyclic voltammetric data collected on the heterobimetallic complexes of both Ni(II) and Pd(II) provide evidence for uranium-centered redox cycling, as well as for the accessibility of other reductions that could be associated with Ni(II) or the organic ligand backbone. Taken together, these results highlight the unique redox behaviors that can be observed in multimetallic systems and design concepts that could be useful for accessing tunable multimetallic complexes containing the uranyl dication.
