Seismic Safety Evaluation of a Full‐Size Reinforced Concrete Frame Infilled With Precast Modular Reinforced Blocks Using Pseudo‐Dynamic Testing and Nonlinear Dynamic Finite Element Analysis
Authors: Jung Ju‐Seong , Lee Kang‐Seok 
Published: November 2024

ABSTRACTThis study proposes a novel seismic retrofitting method involving a reinforced concrete (R/C) frame infilled with precast modular reinforced blocks (PMRBs) to address the limitations of conventional infilling techniques. The retrofitting system for the R/C frame infilled with PMRB maximizes the advantages of factory‐produced modular reinforcement blocks, considerably improving the constructability and joint integrity between the existing frame and the reinforcement, without substantially increasing the structural weight. Moreover, this approach uses a typical frame‐infilling method to enhance lateral load capacity, simplifying the calculation of the required amount of seismic reinforcement; thus, it is ideal for R/C buildings with non‐seismic detailing dominated by shear failure because it helps secure the necessary strength. A pseudo‐dynamic test was conducted using a full‐scale two‐story frame test specimen, based on an existing R/C building with non‐seismic detailing, to verify the restoring force characteristics, strength‐increasing effects, reinforcement strain and seismic response control capabilities of the PMRB frame‐infilling system. Nonlinear dynamic finite element analysis (FEA) was performed to compare and estimate the results of the pseudo‐dynamic test. The study results showed that the average deviation ratio for the seismic response load and displacement between the nonlinear dynamic FEA and the pseudo‐dynamic test was approximately 10%, indicating similar outcomes. Under a design basis earthquake of 200 cm/s2 in seismic intensity, the unreinforced R/C frame experienced shear failure, whereas the PMRB‐reinforced frame sustained only minor earthquake damage, even under seismic accelerations of a maximum considered earthquake of 300 cm/s2 and a large‐scale earthquake of 400 cm/s2. Thus, the newly developed PMRB frame‐infilling system shows great promise for seismic reinforcement.

ABSTRACTObjectiveEating disorders (EDs) and non‐suicidal self‐injury (NSSI) are both phenomena with onset in adolescence. Their co‐occurrence is associated with higher symptom severity and an elevated risk of suicide. In this meta‐analysis, we examine the lifetime prevalence of NSSI in youth with EDs.MethodsWe searched PsycInfo, PubMed and previously published systematic reviews for studies reporting on lifetime NSSI prevalence among children and adolescents (19 years or younger) with an ED (anorexia nervosa, bulimia nervosa, binge eating or other specified feeding and EDs) published until June 2024. A generalized linear mixed model meta‐analysis was performed to estimate the pooled prevalence. Meta‐regressions and multivariate meta‐analyses were conducted to estimate separate prevalence rates based on ED diagnosis and care frame (e.g., inpatient vs. outpatient), respectively.ResultsFifteen studies comprising 3311 children and adolescents were included. Pooled lifetime NSSI prevalence across all ED diagnoses was 34.2% [CI: 27.5%–41.7%]. Heterogeneity was large (I2 = 93.8%). Lifetime NSSI prevalence rates were significantly higher for participants with bulimia nervosa (53.6%) and those with anorexia nervosa binge‐eating/purging type (51.9%) than for participants with anorexia nervosa restrictive type (15.8%).DiscussionThe small number of studies and the large heterogeneity limit the conclusiveness of this meta‐analysis. Results suggest an even higher prevalence of lifetime NSSI in adolescents with an ED than in adults with an ED. The results support previous findings indicating higher prevalence rates of NSSI for EDs associated with binge eating and purging behaviours than for restrictive EDs.

AbstractAlong its 650‐km reach, the Peruvian Amazon River comprises anabranching structures, spanning from the confluence of the Marañón and Ucayali Rivers to the Peru–Brazil–Colombia border. Combining remote sensing techniques and field measurements, this research aims to understand the hydrogeomorphology of these anabranching structures. The multitemporal analysis every 5 years over 35 years (1985–2020) reports channel migration rates, erosion/deposition rates, angles of bifurcations and confluences, among other metrics including the number of channels, length, wavelength average, width and sinuosity, as well as the area, shape and number of islands for each structure. Fieldwork also included hydrodynamic measurements along the Peruvian Amazon River to characterize the flow structure and water fluxes. Results showed that the Peruvian Amazon River developed single (stable) and compound (unstable) anabranching structures at a spatial periodicity of about 22.4 km, with an average displacement speed of approximately 74 m/year. Compound anabranching structures were found at the inlet region (near the origin of the Amazon River) and where significant tributaries flow into the main river and water and sediment fluxes impose destabilizing boundary conditions.
Isotopic and Sedimentologic Proxies of Palaeoexposure Events and Oceanic Anoxic Event 2 (OAE2) in the Cenomanian–Turonian Neritic Carbonates (the Sarvak Formation) in the Abadan Plain, Zagros Basin, Iran

Published: November 2024

ABSTRACTThe shallow marine carbonate deposits of the Sarvak Formation have been deposited in an active tectonic setting under warm and humid climatic conditions during the Cenomanian–Turonian (C–T). The focus of this study is on the sedimentological and geochemical analysis of this formation in the Abadan Plain, Zagros Basin. Petrographic studies led to the identification of five microfacies deposited in the restricted lagoon, tidal flat, reef, shoal and open marine environments. They indicate deposition of the Sarvak Formation on a homoclinal ramp–like carbonate platform. Sequence stratigraphy studies have led to the identification of two third‐order sequences named Cenomanian sequence (DSS‐1) and Turonian sequence (DSS‐2), along with six fourth‐order sequences. The upper boundary of DSS‐1, known as the C–T disconformity (CT‐ES), is subjected to meteoric diagenetic processes, as evidenced by meteoric dissolution (karstification), collapsed brecciation and the development of palaeosols. The upper SB of DSS‐2 is marked by the mid‐Turonian disconformity (mT‐ES), characterised by silicification, brecciation, meteoric dissolution and iron oxide staining of core samples. The significant decreases in δ18Ocarb and δ13Ccarb values indicate a strong effect of meteoric diagenesis beneath the palaeoexposure surfaces. The calculation of sea surface temperatures (SSTs) based on the δ18Ocarb values measured from the unaltered carbonates indicated that the average SST for the C–T is 31.8°C and 30.9°C in K‐01 and K‐02 wells, respectively. A decrease of about 1.5°C is measured during the C–T transition, which indicate a cooling trend of the Late Cretaceous in the Tethyan realm. The carbon isotopic pattern observed in the analysed sections shows correlation with previous studies conducted in the Tethyan region. Additionally, the isotopic composition indicative of Oceanic Anoxic Event 2 (OAE2) is identified around the C–T boundary. Nevertheless, the signature of OAE2 has been somewhat obscured by diagenetic processes associated with C–T palaeoexposure.

ABSTRACTKnowledge of the early Palaeozoic tectonic evolution of the Indochina Block is critical for reconstructions of the Gondwana supercontinent in relation with other microcontinents. In the central Indochina Block, the Early Palaeozoic Tam Ky–Phuoc Son Suture Zone (TPSZ) and Po Ko Suture Zone (PKSZ) demarcate the boundary between the Truong Son Belt in the north and Kon Tum Massif in the south. In the southern parts of Truong Son Belt, we have identified meta‐mafic and meta‐intermediate rocks associated with plagiogranite, metapelitic and meta‐siliceous rocks. Here we present integrated field, geochemical and geochronological results of the meta‐gabbroic and amphibolitic samples in the southern Truong Son Belt to unravel the tectonic evolution of the Indochina Block during the Early Palaeozoic. The MC–LA–ICP–MS zircon U–Pb ages indicate magmatism at ca. 504–460 Ma. Based on geochemical composition, the samples range from gabbro to gabbro‐diorite. The gabbroic samples have slightly higher Mg# (58.9–62.8) than those of the gabbro‐dioritic samples (Mg# = 56.3–61.5), and both types of rock show low TiO2 contents (0.68–0.98 wt%), displaying enriched LREE ((La/Sm)N = 1.66–3.23) and LILE (e.g., Rb, Ba, Th and U), and pronounced negative HFSE (e.g., Nb, Ta and Ti anomalies) with low εHf(t) zircon values (from −6.34 to +0.71). These geochemical characteristics suggest that the metabasic rocks are of subduction‐related arc magmatic processes, and also indicate infiltration of sediment melt from subducting slab to mantle‐wedge prior to its partial melting. The new data suggests that northward subduction under the Truong Son Belt might have initiated during the Early Cambrian, and lasted until around the Middle Ordovician. On a regional scale, the ages of the Early Palaeozoic arc magmatism in the Truong Son Belt are comparable with the ages of tectonic events that occurred in Himalaya, West Qiangtang and East Tibet at the northern margin of the Gondwana supercontinent.

ABSTRACTMantle cell lymphoma (MCL) is an aggressive non‐Hodgkin lymphoma with poor prognosis. The usefulness of fluorine‐18‐fluorodeoxyglucose positron emission tomography/computed tomography (2‐[18F]FDG PET/CT) and its parameters in the evaluation of treatment response and prognosis is not yet clear. The aim of this study was to investigate the prognostic role of tumor burden and tumor dissemination features derived by 2‐[18F]FDG PET/CT in advanced MCL. We retrospectively included 120 patients with advanced MCL who underwent baseline 2‐ 2‐[18F]FDG PET/CT and end‐of‐treatment (eot) PET/CT. The baseline‐PET images were analyzed visually and semi‐quantitatively by measuring the maximum standardized uptake value body weight (SUVbw), lean body mass (SUVlbm), body surface area (SUVbsa), metabolic tumor volume (MTV), total lesion glycolysis (TLG) and dissemination features (Dmax and Dmax‐bsa). EotPET/CT was judged according to the Lugano classification. Progression‐free survival (PFS) and overall survival (OS) were plotted according to the Kaplan–Meier method. At a median follow‐up of 59 months, relapse/progression occurred in 68 patients while death in 38 patients with a median PFS and OS of 27.2 and 57.6 months, respectively. MIPI score, Bulky disease, Ki‐67 index, metabolic response, pretreatment MTV and TLG were significantly associated with PFS at univariate analysis, but only metabolic response, MTV and TLG were confirmed to be independent prognostic factors. Considering OS, only dissemination features were demonstrated to be prognostic features. In conclusions, metabolic response and metabolic tumor burden parameters (MTV and TLG) are strongest predictor of PFS, while dissemination features may have a significant role for predicting OS.

AbstractObjectiveTo evaluate the efficacy of topical chitosan powder in reducing postoperative vaginal bleeding following a loop electrosurgical excision procedure (LEEP).MethodsIn this randomized controlled trial, patients who underwent LEEP were randomly assigned (1:1) to the chitosan group, in which the wound area was sprayed with chitosan powder using a spray pump, or the control group. The primary outcome was the median quantity of vaginal blood lost in the early postoperative period (defined as within 6 h of the procedure).ResultsThe 124 women enrolled in the study were randomly divided into control (n = 61) and chitosan (n = 63) groups. The median amount of vaginal blood loss during the early postoperative period was significantly lower in the chitosan group than in the control group (198.85 [64.4–388.57] mL vs. 250.60 [67.7–552.87] mL; P < 0.001). The rate of late postoperative bleeding requiring hemostatic intervention was also lower in the chitosan group than in the control group (3.2% vs. 16.4%; P = 0.013). Superior cervical wound healing in the chitosan group compared to the control group was also observed.ConclusionThe application of chitosan powder to the cervical wound bed can improve surgical outcomes by decreasing post‐LEEP vaginal bleeding and facilitating the healing of cervical wounds.

Published: November 2024

AbstractObjectiveIn the present study, a bidirectional two‐sample Mendelian randomization approach was utilized to explore potential causal relationships between mitochondrial DNA copy number (mtDNA‐CN) and ovary‐related reproductive disorders (ORRDs), including ovarian dysfunction, ovarian cyst, polycystic ovary syndrome (PCOS), premature ovarian failure (POF) and ovarian endometriosis.MethodsGenetic associations with mtDNA‐CN were obtained from three genome‐wide association study (GWAS) summary statistics from the UK Biobank, and ORRD data were investigated using summary statistics from the FinnGen cohort. Single nucleotide polymorphisms (SNPs) correlated with mtDNA‐CN were selected as genetic instrumental variables (IVs) to estimate the causal effect of mtDNA‐CN on ORRDs using the inverse‐variance weighted (IVW) method with heterogeneity and pleiotropy analysis, and we repeated this in the opposite direction using instruments for ORRDs.ResultsWe found that the genetically predicted mtDNA was indicative of increased levels of PCOS (OR = 1.16; P < 0.001) and ovarian endometriosis (OR = 1.25; P = 0.007) in the IVW analysis and was not associated with the risk of other ORRDs. In the reverse direction, genetically predicted ORRDs were not associated with mtDNA‐CN levels in the IVW analysis. Sensitivity and replication analyses showed the results to be stable.ConclusionWe found that mtDNA‐CN may increase the risk of PCOS and ovarian endometriosis. This may have implications for mtDNA‐CN as a biomarker for these conditions in clinical practice.

AbstractObjectiveThe study's aim was to perform serial placental biometry and Doppler assessments in antenatal women and compare the characteristics of preeclampsia (PE) and normal outcome.MethodsThis prospective cohort study was carried out after ethical clearance. Placental length (PL), thickness, and plavental volume (PV), along with the uterine artery (Ut), middle cerebral artery (MCA), and umbilical artery (UA) blood flow were evaluated serially at 11–14, 20–24, and 28–32 weeks of gestation. The women were followed until delivery, those with PE were considered cases, and those with no other adverse outcome were controls. The placental attributes between cases and controls were compared.ResultsA total of 135/1008 (13.4%) had hypertensive disorders of pregnancy (HDP) and 44/1008 (4.4%) had PE, and no maternal or fetal adverse outcomes were seen in 600 (59.5%) women. The PL and PV were significantly less in those with PE (P = 0.005) than in controls. The ratios of PL/Ut A PI and PV/Ut A PI were significantly lower in cases than in controls in all trimesters (P <0.001). In the first trimester, the area under the curve (AUC), sensitivity, and specificity of PV/Ut A PI for PE prediction were 0.801, 81.8%, and 70.5%, respectively. The sensitivity and specificity of the PL/Ut PI ratio was 81.8% and 70.5%, whereas that at 28–32 weeks was 73.3% & 70.7%.ConclusionPlacental parameters were significantly lower in PE than in normal outcome, and the ratios of PL/Ut A PI and PV/Ut A PI proved to be promising markers.
Importance of proteins and mitochondrial changes as freshness indicators in fish muscle post‐mortem
Authors: Hematyar Nima , Policar Tomas , Rustad Turid 
Published: November 2024

AbstractEvaluating protein and mitochondrial alterations post‐mortem can contribute to determining correlations between fish‐processing parameters and ultimate fish muscle quality. The myofibrillar protein alteration during rigor mortis directly affects the texture of fish muscle. To identify the mechanisms behind post‐mortem softness and quality deterioration, it is crucial to understand the conditions linked to the breakdown of myofibrillar proteins in fish skeletal muscle. Therefore, monitoring protein breakdown at the molecular level and finding target proteins would be considered a marker for fish freshness. Mitochondria play an important role in executing and regulating cell death processes, including apoptosis and necrosis. The mitochondria are the seat of cellular respiration and experience significant alterations in post‐mortem tissues. Processes used to reduce protein degradation, such as optimizing chilling and handling practices, would also minimize mitochondrial changes in fillet quality. Moreover, pH fluctuations are considered a critical point that influences both protein and mitochondrial changes. This review considered the implications of protein and mitochondrial alteration during post‐mortem storage in fish fillets and the possible pathways of their interaction on fillet quality. Mitochondrial characteristics, such as membrane integrity, pH, and ATP levels, are important for post‐mortem muscle cell changes, serving as an early indicator of fish freshness. Understanding the mechanisms behind protein degradation in fish muscle led to maintaining fillet quality and requires further experiments. Label‐free proteomics combined with bioinformatics is crucial for comprehending protein degradation mechanisms to provide customers with safe and fresh fish products while minimizing economic losses associated with fillet deterioration. © 2024 The Author(s).

Published: November 2024

AbstractThe performance control and multidimensional applications of upconversion phosphor have become the hotspot and difficulty in current research and application due to the complex luminescence mechanism. Based on the efficient Gd2O2S: Er3+ upconversion luminescence of 1550 nm excitation and design strategy for co‐doped materials, the multicolor (light green to red) and multifunctional upconversion phosphor Gd2O2S: Er3+, Ho3+ is successfully prepared. Benefiting from the clear mechanism of three‐photon upconversion and energy transfer after co‐doping, the novel applications of Gd2O2S: Er3+, Ho3+ can greatly be expanded. This phosphor can be well used as a fluorescence thermometer due to the higher sensitivity (2.46% K−1@170 K), wider temperature sensing range (170–267 K, Sr > 1% K−1), and greater color variation (Δx = 0.2416, Δy = 0.2483) relative to Gd2O2S: Er3+ and other same type of material. In addition, multiple patterns and encoded outputs are also effectively achieved by the combination of phosphors under multiple light stimuli response. This shows the greater application potential of phosphor in the fields of anti‐counterfeiting and information encryption. This study can also provide a new view to study the more high‐performance and multifunctional upconversion phosphor.
