Self-fertilization does not lead to inbreeding depression in Typha parent species or hybrids
Authors: Rock Danielle , Whitehead Amanda , Parno Kimberly , Bhargav Vikram , Freeland Joanna , Dorken Marcel 
Published: September 2023

Abstract
Some of the most impactful invasive plants are hybrids that exhibit heterosis and outperform their parent species. Heterosis can result from multiple genetic processes, and may also be more likely when parental populations are inbred. However, although outcrossing between relatives and self-fertilization occur in many widespread plants, no study to our knowledge has investigated whether inbreeding in parental populations could help to explain heterosis in hybrid plants that have displaced their parent species. In the wetlands of southeastern Canada there is a widespread Typha (cattail) hybrid zone in which native T. latifolia (broad-leafed cattail) interbreeds with introduced T. angustifolia (narrow-leafed cattail) to produce the invasive hybrid T. × glauca. Typha reproduce through self-fertilization, outcrossing, and clonal propagation. Heterosis has been identified in T. × glauca by comparing proxy fitness measures between hybrids and parent species, but these studies did not consider the potential importance of inbreeding in parental populations. Because F1 hybrids have higher heterozygosity than their parent species, the self-fertilized offspring of hybrids should have higher heterozygosity than the self-fertilized offspring of parent species; the latter should therefore be more inbred, and potentially more susceptible to inbreeding depression (ID). We tested the hypothesis that self-fertilization leads to greater ID in the offspring of T. latifolia and T. angustifolia compared to the offspring of F1 T. × glauca. We conducted common-garden and wetland experiments using seeds from hand-pollinated plants sourced from natural populations, and quantified several fitness-related measures in the offspring of self-fertilized versus outcrossed parent species and hybrids. Our experiments provided no evidence that inbreeding leads to ID in self-fertilized T. angustifolia, T. latifolia or T. × glauca in either a common garden or a natural wetland, and thus show that heterosis in a widespread invasive hybrid does not rely on comparisons with inbred parents.

Authors: verma Archana , Das B. 
Published: September 2023

Abstract
The main purpose of this article is to discuss a few advantages
of Cu (transition metal) doped SnO2
(Sn1 − xCuxO2−δ) bulk
nanoparticles that have been prepared by applying a simple and
reasonably priced technique solid-state reaction method. To analyze
especially, tunning of bandgap and other structural, morphological
properties of Cu-doped SnO2 materials are examined by
different innovative methods. Samples were characterized by XRD
which confirms that SnO2 has a rutile type
tetragonal-shaped structure that goes to the space group
P42/mnm (number 136). SEM images indicate
that SnO2 nanoparticles are inhomogeneous and densely
closed with each other and an average particle size is approx
225–430 nm. The TEM images indicate that grains are present in a
few cubic and spherical shapes. We observed grain size also
increased (20-90nm) when we doped Copper in SnO2
nanoparticles. UV-Vis spectroscopy inspected that the band gap of
(Sn1 − xCuxO2−δ) sample is
increased from 3.531eV to 3.701eV. XPS (X-ray Photoelectron
Spectroscopy) identifies the electronic state of Sn and Cu atoms
found to be 4+ and 2+ respectively. RAMAN
spectroscopy identifies only three vibrational modes, i.e.,
(A1g, B2g, and doubly degenerate
Eg) in pure and Cu-doped SnO2 nanomaterial
(Sn1 − xCuxO2−δ).
Graph representation learning on street networks
Authors: Neira Mateo , Villanueva Roberto Murcio 
Published: September 2023

Abstract
Street networks provide an invaluable source of information about the different temporal and spatial patterns emerging in our cities. These streets are often represented as graphs where intersections are modelled as nodes and streets as links between them. Previous work has shown that raster representations of the original data can be created through a learning algorithm on low-dimensional representations of the street networks. In contrast, models that capture high-level urban network metrics can be trained through convolutional neural networks. However, the detailed topological data is lost through the rasterisation of the street network, and the models cannot recover this information from the image alone, failing to capture complex street network features. This paper proposes a model capable of inferring good representations directly from the street network. Specifically, we use a variational autoencoder with graph convolutional layers and a decoder that outputs a probabilistic fully-connected graph to learn latent representations that encode both local network structure and the spatial distribution of nodes. We train the model on thousands of street network segments and use the learned representations to generate synthetic street configurations. Finally, we proposed a possible application to classify the urban morphology of different segments, investigating their common characteristics in the learnt space.
Atomistic Nucleation Mechanism of MgAl2O4 Inclusion in Molten Steel
Authors: Zhang Hongwei , Lei Hong , Xiao Yuanyou 
Published: September 2023

Abstract
The crystallization process of MgAl2O4 in molten steel begins with nucleation, which determines the structure and size of MgAl2O4 inclusions and is important to investigate the formation mechanism of inclusion. In this work, DFT method was used to calculate the structures and properties of MgAl2O4 clusters and crystal. the formation pathway of MgAl2O4 inclusions at atomic scale in molten has been discussed by the two-step nucleation method. There are three ways to form MgAl2O4 inclusions, and the formation pathways of MgAl2O4 inclusions in steel were decided by the critical values of log([% Mg][% Al]2[% O]4), log([% Mg][% O]) and log([% Mg]3/[% Al]2), respectively, and the critical values of MgAl2O4 inclusions in the three case decreased with the decreasing of temperature. In the nucleation process of MgAl2O4, (MgAl2O4)n clusters can formed by the reactions of [Mg], [Al] and [O], or by the reaction of [Mg], [O] and (Al2O3)n, or by the reaction of [Mg] and (Al2O3)n in steel. The thermodynamic driving force for the formation, aggregation and transformation of (MgAl2O4)n clusters increased with decreasing of temperature.

Abstract
Background and Objectives: Cyclical migraines (C-M) are occasionally met in headache clinics, but not well studied. The aim of the study was to delineate the characteristics of C-M, and compared them with those of cluster headache (CH) and migraine without aura (MO).
Methods: We collected patients with C-M from our headache center, and patients with CH and MO from our cross-sectional standardized survey between 2014 and 2020. Data including demographics, headache characteristics, triggers, and relieving factors were recorded.
Results: Forty-seven patients with C-M were identified. Most of the characteristics of C-M were found to be intermediate between MO and CH, including gender, attack duration, headache degree, headache side, as well as both migraine-like and CH-like accompanying symptoms. C-M had a significant higher percentage of women, and less severe and lower percentages of most CH-like accompanying features compared to CH. On the other hand, C-M had a significant lower percentage of women, earlier onset, shorter duration of headache attacks, more severe, lower percentages of migraine-like accompanying features and higher percentages of CH-like accompanying features compared to MO. However, triggers and relieving factors in C-M were more similar to CH than MO.
Discussion: The largest C-M series defines it as a transition stage between MO and CH. Fewer differences were found between C-M and CH, indicating that C-M may be more similar to CH.

Abstract
The kind and quality of coarse aggregate have a direct impact on flexural strength (FS). As a result, this study used four different types of coarse aggregates, including those that depends on morphology, which contain coarse aggregates that can reach an extreme size of 20 mm and have the appearance of being flaky, angular, rounded, and irregular. The concrete mixtures were made based on Department of Environment (DoE) method of mix design, and a target FS of 5 MPa at 28 days was established. The FS of the concrete mixtures was assessed 7, 14, and 28 days after curing. In addition, the research employed Feedforward neural network (FFNN), Gaussian process regression (GPR), Multilinear Regression (MLR), and Stepwise Linear Regression (SWR) models in the prediction of concrete FS. The FFNN, GPR, MLR, and SWR models were trained on the investigational data obtained from the study's laboratory. The outcome showed that concrete with coarse aggregate in a round form had the maximum slump. Furthermore, the FS of the concrete produced with flaky and irregular coarse aggregates was the same as the FS of the concrete produced with angular and irregular coarse particles. The outcome also shows that the AI-based model (FFNN, GPR, MLR, and SWR) used in the study performs exceptionally well, with an R2-value higher than 0.90 during both the models’ training and testing phases respectively. The results also showed that SWR-M3 outperformed all other models with R2-value = 0.999 throughout the model's testing phase. This depicts that the model is highly accurate and successful in forecasting the concrete FS with various forms of coarse material.

Authors: Ruan Yingding , Cao Wenjun , Xue Hongsheng , You Maoduan , Zhao Zhilong 
Published: September 2023

Abstract
Background:Uniportal Video-Assisted Thoracoscopic Surgery (U-VATS) has emerged as a feasible approach for treating non-small cell lung cancer (NSCLC). However, there is a lack of studies reporting the long-term survival outcomes of U-VATS lobectomy for NSCLC.
Objective:This study aims to compare the perioperative outcomes and long-term survival of U-VATS lobectomy for NSCLC with multiportal VATS (M-VATS, involving two ports or more) lobectomy.
Method: A total of 339 patients who underwent intentional VATS lobectomy for NSCLC between 2012 and 2017 were included in the analysis. Perioperative outcomes and long-term survival were evaluated. Propensity score matching was utilized to minimize baseline characteristic differences between the two groups.
Results:Out of the total cases, 17 (5.01%) were converted to open thoracotomy. The conversion rates were 4.96% (7/141) in the U-VATS group and 5.05% (10/198) in the M-VATS group. A total of 322 consecutive patients underwent VATS lobectomy and mediastinal lymphadenectomy. After propensity matching, 106 pairs were obtained, consisting of 83 males and 129 females. Intraoperative bleeding volume, number of retrieved lymph nodes, explored nodal stations, drainage time and volume, and postoperative hospital stay were similar between the two groups. Both groups exhibited comparable morbidity and mortality rates. From the multivariable analysis, there was no significant difference observed in terms of overall survival (OS) and disease-free survival (DFS) between the two patient cohorts.
Conclusions: U-VATS demonstrated comparable perioperative outcomes and long-term efficacy to M-VATS. However, further confirmation of these findings is required

Abstract
Sainfoin is a very important legume forage that is often planted in arid or semi-arid regions. As herbivorous animal husbandry develops, so does the requirement for sainfoin. However, drought is the main factor limiting the growth of sainfoin. The objective of this study is to explore the response mechanisms of sainfoin varieties/lines to drought stress, which provides the theoretical basis for tolerant breeding of sainfoin. In this study, twenty sainfoin varieties/lines were used as the test materials, the effects of drought stress on growth traits, chlorophyll concentration, leaf water content, osmotic adjustment substances, and antioxidant enzyme activities were determined under simulated levels of drought (− 0.5, − 1.0, − 1.5, and − 2.0 MPa) × exposure times (7 days) in pots. The results showed that leaf area, leaf relative water content, root-shoot ratio, root length, root surface area, root volume, root diameter, root tip number, chlorophyll a content, chlorophyll b content, and catalase activity decreased with increasing drought stress, whereas proline, soluble sugar, soluble protein, and malondialdehyde contents increased in response to drought. Root activity, superoxide dismutase, and peroxidase activities increased first and then decreased and reached the maximum at − 1. 0 MPa. Cluster analysis showed that 20 sainfoin varieties/lines could be divided into 3 categories: (1) High tolerance: new line of P1, Onobrychis viciaefolia ‘Gansu’, code of 1626, and the new line of P2; (2) Moderate tolerance: code of 2323-1, the new line of P3, codes of 2323-2, 2208, 2559, 1668, 7456, 13523, 9977, 13709, 03-132 and 1; and (3) Low tolerance: codes of 2049, 9602, 6, and 7. The findings of these results will help to select the most suitable materials for sainfoin and provide some theoretical basis for cultivating new varieties.

Sungai Bawah Tanah Seropan memiliki peranan yang sangat penting dalam penyediaan air baku di Kabupaten Gunungkidul, sehingga kondisinya dari sisi kualitas dan kuantitas sangat penting untuk dijaga. Penelitian ini bertujuan untuk menganalisis dampak aktivitas antropogenik terhadap kualitas Sungai Bawah Tanah Seropan. Pengambilan sampel airtanah dilakukan setiap dua minggu selama Bulan Februari sampai dengan Juni 2022. Analisis hidrogeokimia yang dilakukan meliputi analisis kimia, fisika dan biologi dengan berfokus pada beberapa parameter yang mengindikasikan terjadinya pencemaran oleh aktivitas antropogenik seperti Nitrat (NO3-), Fosfat (PO43-), Klorida (Cl-), Sulfat (SO4-) dan Koliform Total. Analisis yang dilakukan meliputi analisis matching dengan baku mutu kualitas air, analisis ion dominan dan proses dominan dengan diagram Schoeller dan Trilinear, serta analisis perbandingan ion untuk melihat indikasi dampak aktivitas antropogenik. Hasil penelitian ini menunjukkan bahwa meskipun hanya dua parameter yang melebihi baku mutu (Fosfat dan Koliform Total), tetapi nilai Klorida yang melebihi Natrium pada 3 sampel, korelasi Sulfat yang rendah dibandingkan dengan Anion yang lain serta tingginya kandungan Nitrat dibandingkan Klorida menunjukkan adanya indikasi dampak dari aktivitas antropogenik. Aktivitas antropogenik yang berdampak pada kualitas air Sungai Bawah Tanah Seropan adalah pembuangan black water (tinja) dan pupuk pada aktivitas pertanian.

Published: September 2023

Objectives: This study aimed to assess the impact of bariatric surgery on thyrotropin (TSH), calcium, vitamin D, and lipid profile levels three months post-surgery among patients who underwent the procedure. We also investigated the prevalence of micronutrient deficiencies during the initial three months before and after surgery, along with monitoring the effects of gastric sleeve surgery on body mass index (BMI) reduction.
Methods: The study involved the analysis of data from a cohort comprising 30 patients of both genders who had undergone sleeve gastrectomy due to obesity, with a preoperative BMI of 40 kg/m² or higher. The research spanned from July 2022 to January 2023, with patients undergoing gastric sleeve surgery at Al-Zahrawi Hospital in Nineveh. These patients were subsequently followed up for a period of three months post-surgery.
Results: The study findings demonstrated a significant reduction in TSH, vitamin D, calcium, total cholesterol (TC), triglycerides (TG), low-density lipoproteins (LDLc), very low-density lipoproteins (VLDLc) cholesterol, and BMI in patients who underwent gastric sleeve surgery within the three-month follow-up period, in comparison to their pre-surgery levels. Additionally, there was a noteworthy increase in high-density lipoproteins of cholesterol (HDLc) in the serum of these patients post-operation. The results further indicated positive correlations between TSH, vitamin D, cholesterol, LDLc, and the Atherogenic Index. Likewise, positive correlations were observed between vitamin D, TSH, total cholesterol, triglycerides (TG), and LDLc.
Conclusion: Post-surgery deficiencies in vitamin D, calcium, and TSH levels are attributed to inadequate intake and absorption of micronutrients, highlighting the importance of nutritional supplementation. Sleeve gastrectomy offers a promising avenue for sustained BMI reduction in the long term.

O presente artigo se apresenta como um recorte de uma pesquisa de doutoramento que identificou indicadores qualitativos na escolarização de estudantes com Transtorno do Espectro Autista (TEA) no contexto da educação inclusiva. A Educação Inclusiva se estende para além das escolas como um projeto multidimensional e contínuo, e ao compreendermos suas dimensões, como nos aponta Booth e Ainscow (2002), Echeita Sarrionandía e Ainscow (2011), Humphrey e Lewis (2008), UNESCO-OIE (2018) e Silva e Garcez (2019), nos dedicamos a evidenciar neste texto, a tônica dos espaços formativos aliados aos atendimentos multiprofissionais como contribuição à escolarização dos estudantes autistas. Estes espaços se tornam espaços formativos e de integração de saberes multidisciplinares, interligando políticas de Educação, Saúde e Assistência Social. Sendo assim, trazemos algumas discussões sobre as contribuições e possibilidades para a organização destes espaços.

Cilj rada je utvrđivanje efikasnosti komunikacije između posmatrača i samog dizajna brendiranog vozila, te koliko sam dizajn utiče na količinu prenošenja željenih informacija ka posmatraču i buđenje želje kod istih za daljim istraživanjem o brendu koji se reklamira. Ispitivanje je vršeno preko online Google ankete, gde su ispitanicima predstavljena različita rešenja brendiranih vozila, deset različitih primera, i za svaki primer odgovarali su na pet pitanja. Daljom analizom podataka, došlo se do zaključka koje vozilo i njegov dizajn je ostavio dobar utisak kod anketiranih lica a koje nije. Da bi ovakav vid komunikacije dobro prošao, potrebno je obratiti pažnju na sam dizajn, količinu informacija, dostupnost samih površina za brendiranje, bile one velike ili male, kako ne bi došlo do prenatrpavanja informacijama i stvaranja šuma u komunikaciji.

Segundo a Organização Mundial da Saúde (OMS) a definição de saúde está ligada não apenas à ausência de doença, mas a um estado completo de bem-estar físico, mental e social. Ainda de acordo com a OMS, a prevenção e tratamento de certas doenças mentais, como esquizofrenia e depressão, por exemplo, contribui diretamente para a redução de índices como o de suicídio. O reconhecimento e o tratamento precoce de depressão, dependência do álcool e esquizofrenia, por exemplo, são estratégias importantes. Ainda assim, a prevenção em psiquiatria e saúde mental ainda é muito complexa.

Objectives:
The study presents the magnitude of variation of systolic and diastolic pressures over a few minutes from intra-arterial pressure recordings in 51 hemodynamically stable patients in an intensive care unit.

Materials and Methods:
Conscious surgical ICU patients, with arterial pressure cannulae placed as the standard of care, were recruited after obtaining informed consent. A validated data acquisition system was used to record intra-arterial blood pressure for a period of 10 minutes following a Fast-Flush test. Only those recordings with acceptable dynamic characteristics as per Gardner’s criteria were included in the analysis.

Results:
Three categories of systolic and diastolic pressure variability namely “beat-to-beat” variability, “Respiratory” variability, and “Total magnitude of variation” during the duration of recording, were reported for each of the 51 patients. The mean (± SD) of the total magnitude of variation for systolic and diastolic pressures in the study sample were 21 ± 9 mmHg and 14 ± 5 mmHg respectively.

Conclusion:
Given the magnitude of systolic and diastolic pressure variations over a few minutes, the validity of reporting single- point values for these pressures and using single-point cut-offs for diagnosis and treatment of hypertension must be re-evaluated.
