Mapping the Brazilian Amazon fluvial sensitivity index to oil spills with Shuttle Radar Topography Mission (SRTM) data

Abstract It is important to understand the Solimões River seasonal hydrological cycle and its dynamics to support systematic environmental monitoring efforts in the Amazon region. These are essential to the contingency response to possible accidents in the existing oil transportation network. This study seeks to map the environmental sensitivity to oil spills in the surroundings of Coari city, Amazonas State (AM). A computational method was employed representing the seasonal inundation phenomenon fluctuations, together with data from the Digital Elevation Model generated by the Shuttle Radar Topography Mission. These were matched with Coari fluviometric time series information and a Japanese Earth Resources Satellite-1 (JERS-1 SAR) geo-referenced mosaic of the Global Rain Forest Mapping Project. In this context, a mathematical morphology technique (watershed) integrated with all aforementioned data applying MatLab and ArcGIS computing resources generated results that enabled a better spatio-temporal understanding of the Amazon seasonal dynamics. Thus, the principal product of the research was the Coari fluvial oil spill sensitivity index map based on segmented inundation levels obtained with the proposed methodology.
A 0.4 Hz-335 MHz 130 dBΩ Transimpedance Amplifier with Tunable-Bias for MEMS Oscillators

The paper presents a 0.4 Hz-335 MHz 130 dB transimpedance amplifier (TIA) for driving capacitive MEMS beam resonators. The proposed TIA is a four-stage topology, consisting of a regulated cascaded amplifier, a NMOS Cherry-Hooper amplifier, a CMOS Cherry-Hooper amplifier, and a Common-Source amplifier. The novel part of this work is a tunable control voltage to maintain an appropriate operating point. Implemented on the SMIC 180 nm CMOS process, the TIA was elaborately designed and shows a simulated gain of 130 dB and, a bandwidth of 335 MHz with TIA input/output parasitic of 0.5 pF. The input-referred noise current of the TIA is 1.3 pA/ Hz at the resonant frequency of 20.18 MHz. The TIA drives the MEMS resonator well and oscillation builds up within 50 with a swing of 2.56 Vpp and the MEMS oscillator shows a simulated phase noise of -124.2 dBc/Hz at 100 kHz offset. The power consumption is 26.76 mW under 3.3V supply.
AC Loss of Stacked HTS Tapes Subjected to a Rotating Magnetic Field

The study of AC losses in high-temperature superconducting (HTS) tapes is of great importance. Most previous studies on the electromagnetic properties of HTS have focused exclusively on the AC losses generated by one-dimensional alternating magnetic field and the transmitted current but not on the properties of superconducting tapes in the presence of rotating magnetic fields such as motors. This work, based on finite element simulations under the T-A formulation, explores the AC loss of the central tape in stacked tapes under various conditions, and shows the variation situation of AC losses.
Species richness mediates within‐species nutrient resorption: Implications for the biodiversity–productivity relationship

Between‐species variation in nutrient resorption is one of the mechanisms explaining the positive relationship between biodiversity and primary productivity. Yet, the role of within‐species variations in nutrient resorption in mediating the relationship between biodiversity and productivity remains unclear. We examined how within‐species nutrient resorption, and ultimately productivity, respond to changes in species richness by using four traits related to nitrogen and phosphorus use in four dominant species from different plant functional groups in a biodiversity removal experiment in the temperate steppe. Nitrogen and phosphorus concentrations in both green and senesced leaves in all species significantly decreased with increasing plant species richness, suggesting that plants used those limiting nutrients more efficiently with increasing biodiversity. Plants in higher diversity communities resorbed more nutrients during senescence, which may facilitate reproduction and vegetative regrowth in the next year. Synthesis. Our results highlight the importance of considering within‐species variation in nutrient resorption as an important underlying mechanism explaining the positive effects of biodiversity on primary productivity and ecosystem carbon accumulation.
The NRPS model and its extension for modeling grids with multiple (virtual) synchronous machines

The increase of the number of inverter-interfaced power sources has made the analysis of the stability for such AC grids an important topic. The complexity of such grids comprising many machines, coupled through a complex transmission network makes the stability analysis challenging. Many models have been proposed, of various complexity, to analyze stability and to derive sufficient conditions for stability for transmission line impedances, inertia and droop constants. A simple and moderately accurate model capable of representing the active power dynamics of grids consisting of virtual synchronous machines (VSMs) and synchronous generators (SGs) is the network reduced power system (NRPS) model. In this paper, we show how active and reactive powers as well as the voltages at the filter capacitors of the VSMs can be obtained from the NRPS model by simple computations. We further introduce a new extension of this model called the reactive active power system (RAPS) model, accounting for reactive power control and internal voltage dynamics, by modeling each generator as a third order (nonlinear) system. We compare the performance of this model, the regular NRPS model and high order simulations for a microgrid with four VSMs and four loads. Finally, we show how to accurately tune the parameters of the NRPS and RAPS models to correctly represent a given grid.
Predicting Respiration Rate using Acceleration Sensors and LSTM: A novel Approach

The significance of appraising respiratory rate as a determinant of sleep quality has achieved a firm foundation within the literature. This has led to the emergence of numerous technological solutions encompassing both non-contact and wearable modalities, leveraging sensor mechanisms encompassing cameras, radar, wireless communication, and accelerometers, with the objective of estimating respiratory frequencies. Nevertheless, the efficacy of non-contact methodologies has frequently been compromised when confronted with constrained environmental circumstances, exemplified by low illumination levels and tangible obstructions. Conversely, ongoing investigative endeavors targeting wearable apparatuses have exhibited a predilection for machine learning paradigms; however, the potential for more advanced and precise deep learning models remains inadequately harnessed. Identifying the potential for enhancement, this work presented a novel approach for estimating respiration rates. This involves a synergistic fusion of an accelerometer and an LSTM deep learning model, resulting in superior predictive capabilities for respiratory rate compared to their individual performances. In this experiment, data were collected from 10 teenagers with dynamic respiration rates during various sleep postures (lateral left, lateral right, supine, prone, and sitting). The experiment achieved ±1.962 MAE error in estimating respiratory rates.
Quaternion Gated Recurrent Units for Renewable Energy: Improving Power Forecasting

The unstable nature of renewable energy sources makes it necessary to optimize their management to maximize efficiency and reduce final emissions. In this work, we propose the quaternion-valued gated recurrent unit (QGRU) for the (deterministic) energy forecasting task. The presented models are used for the prediction of Photovoltaic and Wind Power sources, focusing on the GEFCom2014 dataset, which consists of several pieces of information, such as weather data and the corresponding power production collected over different years. The quaternion embedding of the data has been also described. Numerical results and comparisons with state-of-the-art approaches show the effectiveness of the proposed idea, highlighting that the QGRU outperforms most of the time the correspondent GRU model.
DIAGNOSIS AND TREATMENT OUTCOME OF TUBERCULOUS MENINGITIS IN TERTIARY CARE HOSPITAL – TAMIL NADU

Background: Tuberculous Meningitis (TBM) is the most lethal form of tuberculosis. Early diagnosis of TBM remains to be a great challenge for the physicians as the clinical features such as fever, headache, vomiting remains to be non specific. There are many challenges in the diagnosis and treatment of TBM. The aim of this study is to do situational analysis of diagnosis and treatment outcome of TBM in tertiary care hospital, Tamil Nadu. Materials and Methods: A total of 50 patients with Tuberculous Meningitis (TBM) were recruited from Tirunelveli Medical College Hospital between January 2020 and June 2021. Result: In our study among 50 patients, TBM was commonly involved among the age group of 11-30 years, which represents about 38% of the patients. Males were more commonly affected compare to the females. Most common presenting symptom was fever (94%) and headache (80%). Most of them presented under the Medical Research Council (MRC) clinical stage 2 and 3 (84%) with the CSF profile analysis showing protein and lymphocytes count moderately elevated in 2/3rd of patients, and low glucose level in seventy percentage of patients and Globulin positive in 70% of the patients. Among 50 patients two patients had been diagnosed microbiologically with positive CBNAAT test. Meningeal enhancement and hydrocephalus was the most common neuroimaging findings. About ten percentage of patients were associated with pulmonary Tuberculosis. All patients were treated with standardized FDC regimens and selected patients treated with corticosteroids initial period and most of the patients received ATT for 9 months (83%) in our study. Microbiologically diagnosed patients had completed the treatment without any neurological sequel. Among clinically and radiologically diagnosed patients, 70% completed treatment and 18% reported to have persistent neurological deficit. Conclusion: Our findings underscore the complexity of TBM management, emphasizing the need for improved diagnostic tools and targeted therapeutic interventions to enhance treatment outcomes and minimize neurological sequelae in affected individuals. Further research is warranted to explore innovative approaches in tackling the challenges associated with the diagnosis and treatment of Tuberculous Meningitis.
The architecture of submarine monogenetic volcanoes – insights from 3D seismic data

Many prospective sedimentary basins contain a variety of extrusive volcanic products that are ultimately sourced from volcanoes. However, seismic reflection‐based studies of magmatic rift basins have tended to focus on the underlying magma plumbing system, meaning that the seismic characteristics of volcanoes are not well understood. Additionally, volcanoes have similar morphologies to hydrothermal vents, which are also linked to underlying magmatic intrusions. In this study, we use high resolution 3D seismic and well data from the Bass Basin, offshore southern Australia, to document 34 cone‐ and crater‐type vents of Miocene age. The vents overlie magmatic intrusions and have seismic properties indicative of a volcanic origin: their moderate–high amplitude upper reflections and zones of “wash‐out” and velocity pull‐up beneath. The internal reflections of the vents are similar to those found in lava deltas, suggesting they are composed of volcaniclastic material. This interpretation is corroborated by data from exploration wells which penetrated the flanks of several vents. We infer that the vents we describe are composed of hyaloclastite and pyroclasts produced during submarine volcanic eruptions. The morphology of the vents is typical of monogenetic volcanoes, consistent with the onshore record of volcanism on the southern Australian margin. Based on temporal, spatial and volumetric relationships, we propose that submarine volcanoes can evolve from maars to tuff cones as a result of varying magma‐water interaction efficiency. The morphologies of the volcanoes and their links to the underlying feeder systems are superficially similar to hydrothermal vents. This highlights the need for careful seismic interpretation and characterization of vent structures linked to magmatic intrusions within sedimentary basins.
SCF β-TRCP regulates osteoclastogenesis via promoting CYLD ubiquitination

CYLD negatively regulates the NF-κB signaling pathway and osteoclast differentiation largely through antagonizing TNF receptor-associated factor (TRAF)mediated K63-linkage polyubiquitination in osteoclast precursor cells. CYLD activity is controlled by IκB kinase (IKK), but the molecular mechanism(s) governing CYLD protein stability remains largely undefined. Here, we report that SCFβ-TRCP regulates the ubiquitination and degradation of CYLD, a process dependent on prior phosphorylation of CYLD at Ser432/Ser436 by IKK. Furthermore, depletion of β-TRCP induced CYLD accumulation and TRAF6 deubiquitination in osteoclast precursor cells, leading to suppression of RANKL-induced osteoclast differentiation. Therefore, these data pinpoint the IKK/β-TRCP/CYLD signaling pathway as an important modulator of
Watching Intensity and Media Franchise Engagement ∗

The rapid adoption of online streaming and over-the-top services has fundamentally changed at-home entertainment media consumption and given rise to new behaviors which are often characterized by a high intensity of watching (e.g., binge-watching). In this paper, we investigate how the watching intensity affects consumers’ engagement with media franchises in two areas: personal and interactive engagement. The former involves consumers’ adoption and consumption of franchise extensions and the latter concerns consumers’ content generation related to a focal media product they watched. Using individual-level data from an online anime (Japanese cartoons) platform, we find inverse U-shaped effects of watching intensity with the largest effects around three to five hours of watching per day on personal engagement and two to four hours a day on interactive engagement. The positive effects of watching intensity are larger for sequels than other types of franchise extensions. For interactive engagement, our results show that conditional on rating submission, higher watching intensity is associated with higher valence of anime ratings, the most prevalent form of UGC on the platform. We interpret this result as evidence that watching intensity can induce liking.
Drug evaluation in cardiomyocytes derived from human induced pluripotent stem cells carrying a long QT syndrome type 2 mutation

Aims Congenital long QT syndromes (LQTSs) are associated with prolonged ventricular repolarization and sudden cardiac death. Limitations to existing clinical therapeutic management strategies prompted us to develop a novel human in vitro drug-evaluation system for LQTS type 2 (LQT2) that will complement the existing in vitro and in vivo models. Methods and results Skin fibroblasts from a patient with a KCNH2 G1681A mutation (encodes IKr potassium ion channel) were reprogrammed to human induced pluripotent stem cells (hiPSCs), which were subsequently differentiated to functional cardiomyocytes. Relative to controls (including the patient's mother), multi-electrode array and patch-clamp electrophysiology of LQT2–hiPSC cardiomyocytes showed prolonged field/action potential duration. When LQT2–hiPSC cardiomyocytes were exposed to E4031 (an IKr blocker), arrhythmias developed and these presented as early after depolarizations (EADs) in the action potentials. In contrast to control cardiomyocytes, LQT2–hiPSC cardiomyocytes also developed EADs when challenged with the clinically used stressor, isoprenaline. This effect was reversed by β-blockers, propranolol, and nadolol, the latter being used for the patient's therapy. Treatment of cardiomyocytes with experimental potassium channel enhancers, nicorandil and PD118057, caused action potential shortening and in some cases could abolish EADs. Notably, combined treatment with isoprenaline (enhancers/isoprenaline) caused EADs, but this effect was reversed by nadolol. Conclusions Findings from this paper demonstrate that patient LQT2–hiPSC cardiomyocytes respond appropriately to clinically relevant pharmacology and will be a valuable human in vitro model for testing experimental drug combinations.
Can the

Recently there has been a growing trend to recognise the damaging nature of workplace bullying in organisations' Dignity at Work policies. In this article the author explores the negative behaviours experienced by police officers and how the managerial factors that are known to influence OC alter the extent of these bullying behaviours. Using structural equation modelling the findings indicate that negative behaviour is common but the nature of bullying experienced is predominantly indirect and discreet. Senior ranks experience a different mix of behaviours but overall experience higher levels of bullying than junior ranks. The supervision environment was found to be a substantial predictor of the degree of bullying experienced as well as a dominant influence on organisational commitment levels. The findings suggest that bullying research may be advanced when it is considered in a broader frame, where the managerial and organisational factors that create an environment in which bullying is possible and is precipitated are considered. The author suggests that the consequences of poor interpersonal management and communication skills go beyond the expected negative consequences for weak commitment and low involvement because they create an environment in which bullying is more likely. The study is believed to be the first academic study that shows that bullying and commitment behaviours are influenced by the same organisational and managerial factors. The research highlights the importance of the supervision environment and how it might act as a gateway that enables or discourages bullying behaviours.
Understanding informal kinship care: a critical narrative review of theory and research

Many children are cared for on a full-time basis by relatives or adult friends, rather than their biological parents, and often in response to family crises. These kinship care arrangements have received increasing attention from the social science academy and social care professions. However, more information is needed on informal kinship care that is undertaken without official ratification by welfare agencies and often unsupported by the state. This article presents a comprehensive, narrative review of international, research literature on informal, kinship care to address this gap. Using systematic search and review protocols, it synthesises findings regarding: (i) the way that informal kinship care is defined and conceptualised; (ii) the needs of the carers and children; and (iii) ways of supporting this type of care. A number of prominent themes are highlighted including the lack of definitional clarity; the various adversities experienced by the families; and the requirement to understand the interface between formal and informal supports. Key messages are finally identified to inform the development of family friendly policies, interventions, and future research.

EVALUATION OF MANNHEIM PERITONITIS INDEX (MPI) SCORING SYSTEM IN PROGNOSIS OF PATIENTS WITH PERITONITIS IN TERTIARY CARE CENTRE CHENNAI

Background: Acute generalised peritonitis resulting from perforation of a hollow viscus inside the gastrointestinal tract is a medical illness that poses a significant risk to the patient's life.The MPI is a specialised scoring system designed to aid in the early detection of individuals with severe peritonitis, enabling a more proactive surgical approach and ultimately leading to improved patient outcomes. The aim is to assess the effectiveness of the Mannheim Peritonitis Index (MPI) scoring system in predicting the prognosis of patients with peritonitis in a tertiary care hospital in Chennai. Materials and Methods: This research covered all patients who were diagnosed with peritonitis resulting from hollow viscous perforation. The patients were categorised into two groups: survivors and non-survivors. A comparison of scores was conducted between both groups. All patients were monitored until their discharge from the hospital, and they had daily examinations. The efficacy of each rating system was evaluated in predicting the prognosis of the patients. The location of the hole will be determined based on the details provided in the operational process. Result: The mortality rate in our study is found to be 13%. The area under the sensitivity curve and specificity curve was put under roc curve that showed sensitivity of MPI scoring system in the prognosis of the patients with peritonitis is 100% and the scoring system is 90% specific in the prognosis of patients with perforation peritonitis. The MPI has 61.5% Positive Predictive Value and it has Negative Predictive Value of 100% in ruling out the patient with perforation peritonitis. Conclusion: The MPI scoring system is a disease specific and easy accessible scoring system for
Comparison Of Pap Smear With Visual Inspection With Acetic Acid In Screening Of Carcinoma Cervix

Background: Cervical cancer is the second most common among women globally. In most cases of Ca Cervix is detected late due to lack of effective screening programme. Aim: Present aim is to detecting the efficacy of visual inspection of cervix with acetic acid with Pap smear in early detection of carcinoma of cervix. Materials and methods: The cross sectional study conducted in 100 women attending GYN OPD were included in the study. They were screened with Pap smear and VIA, those positive with either of the method were subjected to biopsy. The sensitivity, specificity, PPV and NPV were calculated using biopsy report as the reference standard. Results: The mean age of the study subjects and those with screen positivity were 39.04 yrs and 39.96yrs respectively. Multipara constituted majority of the screened positive cases. Among the study group, white discharge was the predominant complaint. Cervix was clinically healthy in (45%) of the patients and unhealthy in rest of the patients. 21.4 %( 3 out of14) of the cases having healthy cervix on examination had dysplasia. VIA was positive in all the 3 cases and Pap smear was positive in only one case. 25% of the patients had positive VIA. 29% of the patients had mild dysplasia, 16.1% of the patients had moderate and severe dysplasia. Pap smear missed 5 cases of dysplasia and VIA missed 1 case of dysplasia. The VIA sensitivity-92.8%, specificity-29.4%, PPV-52% and NPV-83%. In pap smear sensitivity-64.2%, specificity-76.4%, PPV-69.2% and NPV-72.2% respectively. Conclusions: Thus VIA was more sensitive than cytology. Whereas Pap smear was more specific.
