Thermally stable white light emission and energy transfer analysis of tungstate-tellurite glasses co-activated with Dy3+/Eu3+ for optoelectronic applications

In this study, dual ions (Dy3+/Eu3+) doped tungstate-tellurite (TWKZBi: Dy3+/Eu3+) glass matrices have been formed with the help of the melt quenching approach. The structural, thermal, morphological, and photoluminescent (PL) characteristics, as well as the energy transfer (ET) processes were thoroughly investigated. The structural features of the titled glasses have been explored via X-ray diffraction (XRD) analysis. The morphology and elemental studies of the titled glass matrices were verified with the help of field emission scanning electron microscopy (FE-SEM) along with energy dispersive spectroscopy (EDS). The PL results designate that the TWKZBi doped with Dy3+ ions glass samples exhibit a strong emission peak at 575 nm when excited via n-UV light, whereas Eu3+ doped TWKZBi glass sample demonstrates a conspicuous red emission band at 614 nm when stimulated with the n-UV light. In addition, TWKZBi glasses doped with both Dy3+ and Eu3+ ions demonstrate the emission peaks in the blue (B), yellow (Y) and red (R) zones of the electromagnetic spectrum. The combination of these peaks generates white and orange-red light through properly controlling the activator ion concentrations and selected excitations. Based on Dexter's and Reisfeld's approximation, dipole-dipole (d-d) interaction is responsible for the transfer of energy from donor (Dy3+) to accepter (Eu3+) ions. The decay profiles demonstrate the bi-exponential behavior with a decline in the average lifetime (τavg) values as varying activator (Eu3+) ion concentrations in the titled TWKZBi: Dy3+/Eu3+ glasses. All the results above validate that the titled TWKZBi: Dy3+/Eu3+ glass samples could be fascinating for white LEDs and other optoelectronic applications.

Modification of asthma treatment efficacy by healthcare access: A reanalysis of AsthmaNet Step-Up Yellow Zone Inhaled Corticosteroids to Prevent Exacerbations (STICS) clinical trial

BackgroundWhile randomized controlled trials (RCTs) in asthma management are designed to balance known and unknown variables across treatment groups, including social and environmental co-exposures, it remains important to consider how these co-exposures influence disease progression and treatment outcomes. The importance of considering socio-environmental co-exposures in the context of asthma is twofold: 1) asthma disproportionately affects low-income urban communities, where air pollution and chronic stress are pervasive; and 2) despite the wide range of asthma treatments, inadequate disease control persists. MethodsIn the present ancillary study of the Step-Up Yellow Zone Inhaled Corticosteroids to Prevent Exacerbations (STICS) RCT, we investigated how socio-environmental factors, such as air pollution exposure and healthcare access, modify the effect of inhaled corticosteroid (ICS) therapy in children with asthma. The original STICS RCT evaluated the efficacy and safety of increasing the dose of inhaled glucocorticoids from a baseline daily low dose to five times the daily dose for 7 days in school-age children with mild -to-moderate persistent asthma who began to have short-term loss of asthma control (Jackson et al., 2018 Mar 8) [1]. Our study adds onto those findings by incorporating residential level particulate matter 2.5 μg/m3 (PM2.5) and geographic health provider shortage areas (HPSA) as potential modifiers. ResultsConsistent with the main trial results, we did not find a difference in the number of exacerbations between treatment arms. However, we found the effect of receiving 5xICS, as compared with 1xICS on the time to prednisone was significantly different for children living in areas a shortage of health professionals (HR: 2.09; 95 % CI: 0.74, 5.95) than for children living in no shortage areas (HR: 0.40; 95 % CI: 0.21, 0.77). ConclusionThis finding underscores the importance of considering environmental and social factors in asthma treatment.

The role of emergency medicine specialists and general practitioners in yellow zone patient management: A case in the Sakarya Province

AbstractBackgroundEmergency departments in Turkey employ both emergency medicine specialists (EMSs) and general practitioners due to an insufficient number of EMSs. Patients are triaged into green, yellow, and red codes based on urgency. Typically, EMSs manage more critical patients (yellow and red codes), while general practitioners handle less urgent cases (green codes).ObjectiveThis study investigates differences in patient management approaches between EMSs and general practitioners in the yellow zone of an emergency department in the Sakarya Province.MethodThis retrospective, cross‐sectional study was conducted at the Sakarya Training and Research Hospital from 31 December 2020 to 31 December 2021. The study included patients aged 18 and older who were assigned to the yellow zone and discharged by the attending physician. Data on patient monitoring times, consultation requests, hospitalization rates, resource utilization, readmission rates, and hospital revenue contributions were collected and analyzed. Statistical analyses were performed using IBM SPSS version 21, comparing the performance of EMSs and general practitioners.ResultThe study included 59 physicians (14 EMSs and 45 general practitioners) and a large number of patients. EMSs had significantly more experience, shorter consultation request times, and higher ICU admission rates. They also ordered fewer MRIs and USGs per patient and made more consultation requests. There was no significant difference between EMSs and general practitioners in terms of the number of examinations, patient observation times, ward hospitalization rates, CT orders, readmission rates, and hospital revenue contributions.ConclusionEMSs demonstrated more efficient use of emergency department resources, effective consultation processes, and higher ICU admission rates, indicating better patient management. Despite the limited scope of this single‐center study, the findings highlight the importance of EMSs in improving emergency care quality. Further research is needed to validate these results across multiple centers.

Peran Patroli Perintis Presisi dalam Mencegah Terjadinya Tawuran di Wilayah Hukum Polda Metro Jaya

The phenomenon of brawls in the DKI Jakarta area is increasing due to environmental, economic, and population density factors in the region. The literature references that form the main basis of this research are situational crime prevention theory, iceberg theory, social conflict theory, youth identity theory, as well as the concepts of community policing, and precision inspector patrols. This research uses qualitative methods with data collection techniques of interviews and document studies. The results showed that the role of the Precision Inspector Patrol in preventing fighting in the jurisdiction of Polda Metro Jaya is to ensure that patrols and general guards can run smoothly, be responsible for each assignment, training, and supervision of patrol teams in other units, be the front guard to carry out various preventive and responsive efforts, conduct routine patrols, respond to reports from the public, and maintain the situation in the jurisdiction of Polda Metro Jaya to remain conducive and under control. Through this role, the strategies that can be carried out by the Metro Jaya Police Precision Inspector Patrol Team in preventing fighting crimes are preemptive, preventive, and repressive strategies that are investigative in nature. The community policing policy model in an effort to maximise the implementation of the Precision Pioneer Patrol to prevent horizontal conflicts in the Polda Metro Jaya jurisdiction can be realised through several management stages which include communication and synergy, cooperation, handling, and performance evaluation. Thanks to this, the Precision Pioneer Patrol has been able to reduce the number of horizontal conflicts that occur in the Polda Metro Jaya jurisdiction. The suggestions are for the Precision Pioneer Patrol Team to increase the frequency of patrols at night in the red and yellow zones, for future researchers to apply GIS as an early detection map of conflict-prone areas, and for cooperation partners to expand the scope of programme implementation P2TP2A Unit, PPA Unit, and FKDM to provide an understanding of the importance of Precision Pioneer Patrol in preventing horizontal conflicts.

The Periodic Feeding Frequency of the Juvenile Tropical Rock Lobster (Panulirus ornatus) in the Examination of Chemo-Attract Diet Performance and Colour-Contrast Preference.

Significant research investment into tropical rock lobster (TRL) aquaculture production methods has led to a rapidly developing industry in Vietnam and, more recently, in Australia. The need for an effective formulated feed has been highlighted for both industries; however, feed intake has been a consistent limitation. Visual and chemical cues regulating feed recognition and consumption are expected to yield valuable data, leading to increased feed intake. Lobsters were placed in white- and grey-coloured enclosures to examine the effect of background colour on their feeding behaviour in terms of feeding occurrence and response time. The impact of background colour on TRL feeding behaviour found no statistically significant differences between TRL in white and grey enclosures, suggesting grayscale contrast does not directly affect feeding behaviour. Experiment 2 studied the effects of coloured feeding zones on feeding response in white enclosures. Yellow feeding zones led to a decreased feeding time (473 ± 443 s) and increased time spent feeding (168 ± 1832 s) compared to other colours, possibly due to the yellow-blue chromaticity (b*) contrast. Experiment 3 examined chemo-attractants (glycine, taurine and inositol) and their influence on the feeding behaviour of TRL, but no increased responses were observed. Experiments two and three assessed TRL feeding activity in morning and evening periods, highlighting their nocturnal behaviour, with more feeding occurring in the evening. This project enhances our understanding of photoreceptive and chemoreceptive factors affecting TRL feeding behaviour with formulated feed. It also reveals the potential for background colour changes to enhance marketable colours in commercial settings. Additionally, the study confirmed the effective use of animal tracking software (EthoVision XT) for lobster species tracking in future behavioural trials.

What would affect drivers’ stop-and-go decisions at yellow dilemma zones? A driving simulator study in Hong Kong

Yellow dilemma, at which a driver can neither stop nor go safely after the onset of yellow signals, is one of the major crash contributory factors at the signal junctions. Studies have visited the yellow dilemma problem using observation surveys. Factors including road environment, traffic conditions, and driver characteristics that affect the driver behaviours are revealed. However, it is rare that the joint effects of situational and attitudinal factors on the driver behaviours at the yellow dilemma zone are considered. In this study, drivers’ propensity to stop after the onset of yellow signals is examined using the driving simulator approach. For instances, the association between driver propensity, socio-demographics, safety perception, traffic signals, and traffic and weather conditions are measured using a binary logit model. Additionally, variations in the effect of influencing factors on driver behaviours are accommodated by adding the interaction terms for driver characteristics, traffic flow characteristics, traffic signals, and weather conditions. Results indicate that weather conditions, traffic volume, position of yellow dilemma in the sequence, driver age and safety perception significantly affect the drivers’ propensity to stop after the onset of yellow signals. Furthermore, there are remarkable interactions for the effects of driver gender and location of yellow dilemma.

P023 THE CLINICAL SPECTRUM OF COVID-19 SEVERITY AND OUTCOME ON HOSPITALIZED PATIENTS AT JABRA ISOLATION CENTRE – SUDAN, 2021

Background: The COVID-19 pandemic has highlighted how crucial to comprehend the various clinical presentations of the illness to improve patient treatment and healthcare resources. Objective: To investigate potential gender-based disparities in the severity and outcome of COVID-19 patients in Jabra Isolation Center 2021 Methodology: A descriptive-analytic record-based study was conducted at Jabra Isolation Centre, Sudan, 2021. A random selection of 317 patients was performed. The three zones of severity were: mild (ward stay, Green Zone), moderate (high dependence unit, Yellow Zone), and severe (intensive care unit, Red Zone). Fever, SOB, cough and SPO2, and mortality based on the 3 zones and gender distribution were analyzed by MOH triage procedure checklist using SPSS(version 21) Results: The age ranged between 25-91 years. The findings were as follows: At Green Zone, 46.63% of patients were admitted, with 65.91% being males, The hypertensive patients were 38.16%, and the diabetic were 39.47%. The presenting signs were fever, SOB, cough, and SPO2 (77.39%, 67.11%, 56.58%, and 92% respectively). The mortality rate was 52.63%. While at Yellow Zone, 15.64% of patients were admitted, with 75% being males. The hypertensive patients were 49.02%, and the diabetic were 39.22%. Fever, SOB, cough, and SPO2 were (78.43%, 74.51%, 70.59% and 90% respectively). The mortality rate was 49.02%. At the Red Zone, 37.73% of patients were admitted with males 61.05%. The hypertensive patients were 45.53%, and the diabetic were 36.59%. Fever, SOB, cough, and SPO2 (65.85%, 71.54%, 43.9%, and 92% respectively). The mortality rate was 62.6%. The mortality rate across all 3 zones of severity was 55.83% of which males were 66.0%. Conclusions: This study showed that COVID-19 hospitalized patients at Jabra Isolation Centre in 2021 were predominately males and associated with hypertension and diabetes at 3 zones of severity. The mortality rate was highest at the Red Zone. The overall mortality rate was 55.83% of which males were 66%.

Regional ecological risk assessment through the application of production-living-ecology land use function indicators: a case study of the eco-economic zone of Yellow River Delta.

To date, land use structure information has been employed extensively for ecological risk assessment (ERA) purpose in regional/landscape scales; in contrast, land use function (LUF) information-based ERA research is still scarce. Therefore, it is necessary to carry out more ERA case studies in macroscale with the help of pertinent LUF indicators. As an important way to construct production-living-ecology LUF indexes, this study employs the weighted stacking method and related economic statistical data for regional ecological risk assessment (RERA) purpose within Yellow River Delta High-efficiency Eco-economic Zone (YRDHEZ), China. This YRDHEZ-RERA research pointed out that (1) it was rational to use a series of economic statistical data to more comprehensively and precisely characterize regional production and living function grades in YRDHEZ. (2) The Yellow River Delta had lower agriculture and non-agriculture production functions, whereas the rest of the zone had higher production functions. (3) Most people lived in the south part, whereas north coastal zone had very low population density; the east part had higher per capita disposable income of urban/rural households than that of west. (4) The south part of the zone had higher production/living functions and integrated ecological risk source intensity than those of north coastal zone, whereas the coastal zone had higher ecology function, eco-environmental vulnerability, and final integrated ecological risk than those of inland region. As for regional ecological risk management, establishing nature reserve with strict spatial governance for coastal/estuarine wetlands and coordinating production/ecology functions of coastal salterns/breeding ponds are relevant feasible measures.

Personalizing driver safety interfaces via driver cognitive factors inference

Recent advances in AI and intelligent vehicle technology hold the promise of revolutionizing mobility and transportation through advanced driver assistance systems (ADAS). Certain cognitive factors, such as impulsivity and inhibitory control have been shown to relate to risky driving behavior and on-road risk-taking. However, existing systems fail to leverage such factors in assistive driving technologies adequately. Varying the levels of these cognitive factors could influence the effectiveness and acceptance of ADAS interfaces. We demonstrate an approach for personalizing driver interaction via driver safety interfaces that are are triggered based on the inference of the driver’s latent cognitive states from their driving behavior. To accomplish this, we adopt a data-driven approach and train a recurrent neural network to infer impulsivity and inhibitory control from recent driving behavior. The network is trained on a population of human drivers to infer impulsivity and inhibitory control from recent driving behavior. Using data collected from a high-fidelity vehicle motion simulator experiment, we demonstrate the ability to deduce these factors from driver behavior. We then use these inferred factors to determine instantly whether or not to engage a driver safety interface. This approach was evaluated using leave-one-out cross validation using actual human data. Our evaluations reveal that our personalized driver safety interface that captures the cognitive profile of the driver is more effective in influencing driver behavior in yellow light zones by reducing their inclination to run through them.

Exploratory Analysis on the Livability of a City with Digital Placemaking in Jakarta Timur, Indonesia

Abstract People who work in Jakarta to prefer suburban areas as their homes, such as Jakarta Timur. Urban livability directly influences the quality of life of the citizens. The purposes of this study on Jakarta Timur: 1) understanding the public space roles and values; 2) finding out the types of public spaces; 3) understanding the connection between livability and the value of public spaces; and 4) exploring new placemaking research method of using big data. The methodology included data collection (government documents, news articles from trusted sources, Google Reviews via Octoparse 8, and Google Map), data visualization (wordclouds and QGIS), and data analysis (word frequency, sentiment, and accessibility). The area’s socio-demographic study estimated that the reviews are dominantly written informatively and expressively by locals with certain characteristics (must be proven in future studies). It was also revealed that Jakarta Timur is comprised of more yellow zones (housing) with only a little green zone (already including the selected public spaces). The recurring motives for visitation included doing sport and playing with family/children and the sentiment analysis reflected overall positive values on the citizens. Regarding accessibility, it was found that despite preferring private transportation, the willingness to ride the public transportation still existed.

Spectroscopic characterization of rare natural pink diamonds with yellow color zones

A set of 28 uncommon pink diamonds with yellow color zones are identified among thousands of natural pink diamonds examined. The pink color in these diamonds is caused by the 550 nm absorption band associated with plastic deformation, and is concentrated along straight lamellae (also known as deformation lines). These pink diamonds are type Ia with nitrogen concentrations ranging from 118 to 313 ppma, predominantly as A-centers, i.e., type IaA ≫ B (proportion of B-center < 10 %) to IaA > B (proportion of B-center = 11–26 %).Yellow color zones are observed on or beneath the surface of these faceted pink diamonds. Yellow fluorescence and occasionally yellow phosphorescence excited by long-wave (365 nm) or deep UV (<225 nm), corresponding to the yellow color zones, are commonly observed in yellow diamonds colored by the 480 nm absorption band. PL mapping conducted on the diamond surface and along the depth of the pink diamonds in this study reveals that the yellow color zones have features associated with the 480 nm absorption band. Some of these features are associated with nickel-related defects, and are only detected within the yellow color zones. This suggests that the yellow color zones formed in a different growth episode or from a different diamond-forming fluid than the remaining volume of the diamond with pink body color. Post-growth plastic deformation created defects giving rise to the 550 nm absorption band, producing a pink body color to diamond that was presumably colorless, and producing brown color in zones that may have had pre-existing yellow color. Three diamonds in this study contain eclogitic mineral inclusions, indicating that they formed in association with mantle eclogite, prior to plastic deformation.

Eight mineral species in one crystal: unique zonation of polychrome tourmaline from the Krutaya vein (Malkhan pegmatite feld, Transbaikalia, Russia)

A unique unusually Mn-rich concentrically zoned polychrome crystal from the cavity of granite pegmatite of the Krutaya vein within the Malkhan pegmatite feld (Transbaikalia) is studied. It consists of six valid and two potentially new mineral species of the tourmaline supergroup. The paper provides the detailed physical, chemical and crystallographic characteristics of minerals. A Mn-richest (up to 9.6 wt. % MnO) dark brown core of the crystal is composed of fuor-tsilaisite, princivalleite and a Mn2+-F-analog of foitite. A greenish yellow intermediate zone consists of Mn-rich fuor-elbaite and darrellhenryite and is followed by a Mn-poor pink zone composed of fuor-rossmanite, rossmanite and their O2--analog. A yellowish green peripheral zone consists of late-generation Mn-bearing fuor-elbaite. The Mn content decreases, while the Li + Al content increases from the center of the dark brown zone to the margin of the crystal approximately to the middle of the pink zone, where the evolution of the tourmaline composition is inverted and this trend becomes opposite. The crystal structure of fuor-tsilaisite is refned on a single crystal extracted from this specimen, R1 = 2.4 %. The mineral is trigonal, space group R3m, a = 15.9595(1), c = 7.14164(7) A, V = 1575.31(3) A3, Z = 3.

Compound- and element-specific accumulation characteristics of persistent toxic substances and metals in sediments of the Yellow Sea

This study investigated the large-scale distributions of persistent toxic substances (PTSs) and heavy metals in sediments of the Yellow Sea, collected from six transects between latitudes 32 and 37 degrees north (n = 35). Elevated concentrations of polychlorinated biphenyls (PCBs) were detected near the mainland, with a predominance of low-chlorinated congeners (di to tetra, ∼60%), indicative of atmospheric deposition. Analysis of traditional and emerging polycyclic aromatic hydrocarbons (t-PAHs and e-PAHs) revealed notable enrichment in the Central Yellow Sea Mud Zone (CYSM), attributing fossil fuel combustion as the significant source. Styrene oligomers and alkylphenols exhibited notable accumulation near the Han River Estuary in South Korea and the Yangtze River Estuary in China, respectively. The accumulation of heavy metals was predominantly observed in the CYSM, with element-specific distribution patterns. Cluster analysis revealed distinct distribution patterns for PTSs and metals, highlighting their source-dependent and grain size-dependent behaviors. In addition, the distribution and accumulation of PTSs tended to depend on their partitioning coefficients, such as the octanol-air partition coefficient (log KOA) and octanol-water partition coefficient (log KOW). This study offers valuable insights into the sources, transport, and fate of hazardous substances in the Yellow Sea, emphasizing the necessity for targeted environmental management strategies.

Impact of the tripartite interaction between rice, sheath blight and diverse crop-associated endophytes on phenotypic and biochemical responses in rice

Endophytes stimulate plant growth and inhibit phytopathogens. Most of the known endophytes are host-specific and only a few strains are effective for practical field use. Thus, this study focuses on the evaluation of endophytes viz., Bacillus pseudomycoides strain HP3d, Paenibacillus polymyxa strain PGSS1, B. velezensis strain A6 and P42 isolated from diverse crop ecosystems for their potential to promote plant growth and induce systemic resistance against sheath blight disease in rice. The endophytes were studied for plant growth promoting traits in vivo conditions and were found to exhibit ammonia (light to strong), siderophore (yellow zone on the CAS agar plate), indole-3-acetic acid (15.20–22.19 μg mL−1) production and phosphorus solubilization (1.2–1.5 cm). In the glasshouse, when applied individually and in combinations through various methods like seed treatment, seedling dip, and foliar spray these endophytes significantly reduced lesion size (2.06–2.37 fold) and ShB severity (2.60–2.58 fold), enhancing growth parameters viz., shoot (1.09–1.11 fold), root (1.02–1.20 fold), number of tillers (1.2–1.6 fold), shoot (80.58–82.64 %) and root (62.01–66.66 %) dry matter over untreated control. Consequently, enzyme activity viz., polyphenol oxidase (2.20–3.00 U−1min−1g−1), peroxidase (0.31–0.35 min−1g−1), superoxide dismutase (118.50–123.00 Ug−1 FW), and phenylalanine ammonia lyase (0.84–0.90 min⁻1g⁻1FW) was found to increase up to the fourth day after the pathogen challenge and subsequently decrease thereafter. Chlorophyll content post inoculation of ShB declined over time but endophyte treated plants exhibited lesser reductions over uninoculated control. Field trials corroborated the in vitro findings, demonstrating reduced ShB (1.71–1.88 fold decrease in PDI) and enhanced growth (1.1–1.2 fold increase in shoot length) over untreated controls. The combined application of seedling dip, seed treatment, and foliar spray proved to be the most optimum treatment. The findings highlight the potential of diverse crop-derived endophytes, emphasizing their non-host specificity and effectiveness as broad-spectrum bioagents in actual field conditions.

Safety First or Saving Lives? How Medical Responders Would Decide when Facing an Active Violent Incident. Results from an Explorative Cross-National Survey

Abstract In recent years, public authorities and rescue services have been discussing how Medical First Responders (MFRs) should behave in an Active Violent Incident (AVI) where it is necessary to weigh up self-protection and the rescuing of others. The aim of this exploratory study is to generate a preliminary picture of how European MFRs position themselves on this and related questions. With the help of a network of experts, an AVI scenario and accompanying questionnaire were developed and pretested. A refined version was then distributed among MFRs in eight European countries and Israel. We performed descriptive statistics and tested for significant differences among the participating countries. 1164 MFRs completed the survey. In the absence of police protection, a majority of respondents opted against providing immediate casualty care (56.6 %). Under certain circumstances, however, the rest decided in favour. More than 65.5 % did not fear disciplinary or legal consequences for not providing assistance immediately. Even with police protection, one in ten respondents would still not enter a “yellow zone”, one in four would leave this to Emergency Medical Services (EMS) units specifically trained for such operations. While there are very few strong contrasts between MFRs with different work experience, roles (supervisor/instructor) or additional qualifications (e.g., firefighting, military service), there are significant differences between MFRs from participating countries. Most notably, (1) only Norwegian participants identified, on average, a clear paradigm shift from “safety first” to “controlled risk taking”; (2) while 69.8 % of the Austrian cohort were unwilling to enter without being escorted by the police, among Norwegians MFRs the figure was 42.7 %; (3) the question whether “weapons” are “useful” equipment in such a scenario is particularly divisive (ranging from 14.3 % of German to 58.9 % of Israeli respondents). Although most of the questions were answered in the same way by a large majority, significant differences can be observed, especially between countries. We offer various explanations for these and discuss whether MFRs can actually remain passive given the situational normative forces inherent to an AVI.

Tourmaline as a petrogenetic indicator highlighted in a multicoloured crystal from the gem deposit of Mavuco, Alto Ligoña pegmatite district, NE Mozambique

Abstract A rounded fragment of a multicoloured tourmaline crystal (2.5 cm diameter), collected from the secondary gem deposit of Mavuco, Alto Ligoña pegmatite district, Mozambique, has been investigated using a multi-analytical approach, with the objective of reconstructing its growth history. The sample represents a core-to-rim section, perpendicular to the c axis, of a crystal characterised by a variety of colours. These change from a black core to an intermediate zone with a series of colours, yellow, blue–green and purple, to a final dark-green prismatic overgrowth. These changes are the result of a wide variation in Fe, Mn, Ti and Cu concentrations and their redox state. The black core is characterised by enrichment in Fe and Mn, with iron present in its divalent state. The yellow zone shows a progressive depletion in Fe and its colouration is caused by Mn2+ and Mn2+-Ti4+ IVCT interactions. The progressive decrease in Mn coupled with the absence of Ti, and the lack of Fe, implies that Cu2+ acts as the only chromophore in the pale blue–green zone. The dominant colour-causing agent of the purplish zone is Mn3+, denoting a change in redox environment; however, even though the amount of Cu remains significant, its chromophore effect is obscured by Mn3+. The dark-green prismatic overgrowth, characterised by a sharp increase in Fe, Mn and also Ca, is interpreted as a late-stage partial re-opening of the geochemical system. This occurrence could potentially be related to mechanical instability of the cavity in which the crystal grew.

Impacts of spatial and temporal patterns and economic development on carbon emissions in Chinese cities

With the economic and social development and the improvement of peoples living standards, the urban carbon emission increases. Studying the influence of industrial structure and spatial patterns on carbon emission under the economic development of different cities can help to find the main factors affecting carbon emission, formulate policies to solve the problem according to local conditions, and provide an important scientific basis for the transformation of economic growth mode and the construction of low-carbon cities. This paper draws conclusions by analyzing the trend curves of urban carbon emissions and economic factors over the years. Different regions of the citys economic development potential differences are obvious, and the potential for greater spatial concentration of cities; citys economic development potential in the spatial and temporal distribution of key cities and major urban agglomerations as the basis for the point - line - surface in order to promote. economically developed cities, the total carbon emissions, carbon emissions growth rate of a declining trend; economically underdeveloped areas, the total carbon emissions, carbon emissions growth rate of a year-on-year trend; the degree of carbon emissions and the degree of prosperity of the secondary industry is closely linked. Chinas urban carbon emissions have a significant positive spatial correlation between 2006 and 2016, the cold spot area of urban carbon emissions is relatively stable, mainly distributed in the eastern and southern economic zones, while the hot spot area is mainly distributed in the northwest, northeast and the middle reaches of the Yellow River economic zone.

Artificial Intelligence, Intrapartum Ultrasound and Dystocic Delivery: AIDA (Artificial Intelligence Dystocia Algorithm), a Promising Helping Decision Support System.

The position of the fetal head during engagement and progression in the birth canal is the primary cause of dystocic labor and arrest of progression, often due to malposition and malrotation. The authors performed an investigation on pregnant women in labor, who all underwent vaginal digital examination by obstetricians and midwives as well as intrapartum ultrasonography to collect four "geometric parameters", measured in all the women. All parameters were measured using artificial intelligence and machine learning algorithms, called AIDA (artificial intelligence dystocia algorithm), which incorporates a human-in-the-loop approach, that is, to use AI (artificial intelligence) algorithms that prioritize the physician's decision and explainable artificial intelligence (XAI). The AIDA was structured into five classes. After a number of "geometric parameters" were collected, the data obtained from the AIDA analysis were entered into a red, yellow, or green zone, linked to the analysis of the progress of labor. Using the AIDA analysis, we were able to identify five reference classes for patients in labor, each of which had a certain sort of birth outcome. A 100% cesarean birth prediction was made in two of these five classes. The use of artificial intelligence, through the evaluation of certain obstetric parameters in specific decision-making algorithms, allows physicians to systematically understand how the results of the algorithms can be explained. This approach can be useful in evaluating the progress of labor and predicting the labor outcome, including spontaneous, whether operative VD (vaginal delivery) should be attempted, or if ICD (intrapartum cesarean delivery) is preferable or necessary.

Unraveling Parent Rock and Mineral Influences in Tropical Weathering Profiles: REE, Nd and Sr Isotopic Geochemistry

This study aims to investigate the effects of parent rock and minerals on lateritic weathering. The study presents X-ray diffraction (XRD), whole-rock geochemistry, and Nd-Sr isotopic data for examining two profiles, 10 and 12 m thick, respectively, that illustrate the regional tropical weathering status in the Midwest of Brazil. The profiles, developed from metasedimentary and sedimentary rocks, are constituted by saprolite, mottled horizon, lateritic duricrust, and oxisol. Across the profiles, the minerals controlling the weathering geochemistry are muscovite, microcline, quartz, kaolinite, hematite, goethite, and gibbsite. Red and yellow zones in the saprolite and mottled horizon as well as the lateritic duricrust with breccia/fragmental, pisolitic, and oolitic textures make profile 1 more complex. In contrast, profile 2 has an oxisol that mantles the homogeneous vermiform lateritic duricrust. Fe2O3, accumulated during surface weathering, is a potent element in the geochemical profile control since it forms the harder goethite to hematite lateritic duricrust, bearing most of the trace elements (As, Cu, Cs, Pb, Sc, Sr, Th, U, V, and Zn) with similar ionic radii and electrovalence. The LREE have affinity for the elements of the Fe2O3 group of the lateritic duricrust. On the other hand, the K2O group together with Zr and TiO2 e in the phyllite, saprolite, and mottled horizon of profile 1, are associated with the HREE. Additionally, in profile 2, the HREE are mostly associated with the Al2O3 group and the residual minerals in the oxisol. The indication that REE is associated with phosphates, zircon, rutile/anatase, cereanite, and muscovite/illite, which have variable weathering behavior, caused the REE fractionation to occur across and between the profiles. Despite the REE fractionation, the ƐNd(0) values along the profiles consistently maintain the signature of the parent rock. Muscovite and microcline weathering, in profiles 1 and 2, respectively, control the decrease in 87Sr/86Sr signatures of both profiles and the distinct radiogenic ratios. The development of lateritic duricrust in both profiles indicates a similar weathering intensity, although the gibbsite–kaolinite predominance in the oxisol of profile 2 highlights a geochemical reorganization under humid conditions, as well as near-intense soluble silica leaching.
