Indoor positioning within a floor poses significant challenges to researchers and industrialists. In this paper, we propose an indoor positioning system based on Wi-Fi fingerprinting and a transformer model in deep learning. Initially, we convert Wi-Fi samples into AP-RSSI range pairs. Subsequently, we construct a Location Space and generate spatially correlated and combined Wi-Fi samples as the model inputs to enhance the positioning accuracy. Furthermore, we introduce a novel spatial label smoothing method to improve model training efficiency and positioning precision. Experimental results show that our approach effectively enhances indoor positioning accuracy at a lower sampling cost compared to previous methods in the literature.

Mandatory fortification (MF) of wheat flour (WF) with iron/folic acid, refined edible oil with vitamin A (VA), and salt with iodine is implemented to address micronutrient deficiencies in Senegal. The effectiveness of fortification depends on food vehicles meeting fortification standards (FS). The objective of this study is to assess iron, VA, and iodine content of WF, oil, and salt, respectively, and compare them with FS. A cross-sectional market survey was conducted in the Dakar region and the neighboring city of Thiès. Samples of all available brands of WF, oil, and salt in the scope of MF were collected at 25 sampling sites. Qualitative tests were conducted, and positive samples were pooled by brand and type, and then analyzed using atomic absorption spectrophotometry (iron), iCheck Chroma3 (VA), and titration (iodine). Micronutrient content of food vehicles was compared with FS. Overall, 142 WF, 372 oil, and 140 salt samples were collected from 27, 69, and 31 brands, respectively. The qualitative results showed that 26.8% of WF, 44.6% of oil, and 23.6% of salt were not fortified. After quantitative analysis, 51.4% of WF, 17.3% of oil, and 16.3% of salt were found fortified below the standard minimum. The positive brand composite samples had the following median contents of iron, VA, and iodine: 17.5, 10.8, and 33.3 mg/kg, in WF, oil, and salt, respectively, and which were below, around, and above the minimum value of the corresponding standards, respectively. Disparities were observed by the origin of production, between domestic producers, and by type of food vehicle. Fortification quality gaps remain an issue in Senegal, and further action is needed to comply with FS and to realize the potential of food fortification for public health.

This wireless monitoring system is developed to alert and warn the resident regarding the upcoming flood. Due to the floods that occur every year, especially during the monsoon season, the loss and damage done by this disaster are uncontrollable. When the water level rise-up above the safe ground, it may hit the communication substation, as well as the power tower. In most cases, many residents are not alert with their surroundings because there is no alert system that can remind them regarding to the issues that will arise. By not preparing themselves for the upcoming nature disaster, it could endanger themselves and destroy their property. Thus, this project focus on monitoring a real-time river water level system for flood prediction purposes which utilize three devices connected together in a centralized system. By having this system, people will be notified about the current situation and the water level of the river near to them via Internet of Things (IoT) such as Blynk application. ESP32 and ESP32-Cam are used as the main microcontroller to control the system. The sensor used to detect the water level at the river is TF Mini Lidar and ultrasonic sensor for the water level detection of the rain gauge. The ESP32-cam are used to monitor the surrounding area at the river. The combination of these three systems is used to monitor and predict the flood occurrence.

Long-term antiplatelet agents including the potent P2Y12 antagonist ticagrelor are indicated in patients with a previous history of acute coronary syndrome. We sought to compare the effect of ticagrelor with that of aspirin monotherapy on vascular endothelial function in patients with prior acute coronary syndrome. This was a prospective, single center, parallel group, investigator-blinded randomized controlled trial. We randomized 200 patients on long-term aspirin monotherapy with prior acute coronary syndrome in a 1:1 fashion to receive ticagrelor 60 mg BD (n=100) or aspirin 100 mg OD (n=100). The primary end point was change from baseline in brachial artery flow-mediated dilation at 12 weeks. Secondary end points were changes to platelet activation marker (CD41_62p) and endothelial progenitor cell (CD34/133) count measured by flow cytometry, plasma level of adenosine, IL-6 (interleukin-6) and EGF (epidermal growth factor), and multi-omics profiling at 12 weeks. After 12 weeks, brachial flow-mediated dilation was significantly increased in the ticagrelor group compared with the aspirin group (ticagrelor: 3.48±3.48% versus aspirin: -1.26±2.85%, treatment effect 4.73 [95% CI, 3.85-5.62], P<0.001). Nevertheless ticagrelor treatment for 12 weeks had no significant effect on platelet activation markers, circulating endothelial progenitor cell count or plasma level of adenosine, IL-6, and EGF (all P>0.05). Multi-omics pathway assessment revealed that changes in the metabolism and biosynthesis of amino acids (cysteine and methionine metabolism; phenylalanine, tyrosine, and tryptophan biosynthesis) and phospholipids (glycerophosphoethanolamines and glycerophosphoserines) were associated with improved brachial artery flow-mediated dilation in the ticagrelor group. In patients with prior acute coronary syndrome, ticagrelor 60 mg BD monotherapy significantly improved brachial flow-mediated dilation compared with aspirin monotherapy and was associated with significant changes in metabolomic and lipidomic signatures.

Abstract In the oil and gas industry, operators strive to minimize loss time and production while keeping its facilities and operations safe. Over the past few decades, technological innovation has equipped the industry with the equipment and practices necessary to make the exploration and production more efficient, safe and environmental friendly. This paper discusses successful implementation of several non-intrusive technologies by the operator for redevelopment of maturing oilfield in offshore East Malaysia. The field was discovered in 1967 and oil has been produced since 1972 from the major hydrocarbon accumulation in 8 producing reservoirs, sandwiched between shallow gas-bearing reservoirs and deeper gas/condensate-bearing reservoirs. Enhanced Oil Recovery (EOR) redevelopment project in the field began in 2018, targeting the major oil reservoirs and Non-Associated Gas (NAG) reservoirs. Crestal gas injection and flank water injection will be implemented to further develop the oil rims of A and B reservoir while Immiscible Water-Alternate-Gas (IWAG) injection will be implemented in the C reservoir. The EOR scheme will include infill drilling of new wells and workover of existing wells to deliver targeted incremental oil recovery. The journey towards EOR redevelopment project consistently requires integrated contributions from multiple disciplines such as Petroleum Engineering, Production, Well Services, Facilities and Process Engineering, which has been facilitated effectively through Reservoir, Well and Facility Management (RWFM). This holistic work process involves creating critical strategy for EOR redevelopment activities, optimization decisions and asset management, ensuring the delivery of remaining reserves and long-term production maximization. By implementing RWFM collaboration and support, several non-intrusive technologies have been evaluated &amp; implemented to solve long overdue problems such as online acoustic sand monitoring system, non-intrusive acoustic valve inspection device and active sonar meter. Overall, this paper highlights the working principles, actual field results and lessons learnt from the application of non-intrusive technologies through RWFM collaboration that deliver significant cost and efficiency benefits as well as safety for prudent brown field EOR redevelopment.

ABSTRACT Adaptation finance addresses the effects of climate variability and change on development and physical insecurity. Yet, adaptation has proven difficult to systematically measure and assess, resulting in a lack of coherent and comparable evidence to learn about good adaptation practice. Measurement has become even more challenging since the integration of resilience into policy framings. Measuring climate resilience requires evidence of resistance to, and recovery from, shocks and stresses. But resilience of what, to what seldom guides the design of assessments. Researchers tend to use proxy indicators and aggregated units of analysis that cloud the relationships under study, and crucially, leave unclear the interactions between climate and development. This viewpoint documents these common barriers to progress in the field. It then outlines two methods for practitioners and researchers to link climate shocks and stresses to climate-sensitive development outcomes as a key first step to research and evaluation design. Both methods enable prediction of expected levels of development outcomes, given the extent of climate shocks and stresses, which is then comparable with actual levels achieved under climate resilience interventions. The product is standardized and comparable metrics to learn about the performance of climate adaptation policymaking and resilient development programming.

In this paper we observe and simulate the effect of ultrasonic standing waves on elongated obj ects, including interactions between multiple objects. Alignment of 25–40 micrometer long and 10 micrometer diameter glass rods has been observed in water when standing waves were excited by a PZT actuator at 2.1 MHz. COMSOL has been used to simulate the acoustic fields for one or more rods in water. The stress tensor was determined from the acoustic field, and then the force and torque on the rods was calculated using well-established expressions. The results give insight into the formation of aggregations of objects.

Background: Sham-controlled neurofeedback (NFB) trials consistently find no separation on ADHD outcome measures leading many to conclude that NFB’s beneficial effects are due to placebo. Method: We deconstruct the NFB training methodology and findings of six sham-controlled trials that assessed for evidence of learning. Results: All six studies found no evidence NFB subjects learned to self-modulate the targeted electroencephalogram (EEG). Careful analyses revealed these studies’ training methodologies were antithetical to the established science of operant conditioning thereby preventing subjects from learning to self-modulate. These findings are in marked contrast to NFB studies whose methodology mirror the best practices of operant conditioning. Conclusion: The premise that NFB’s beneficial effects are due to placebo phenomenon is unproven as these studies compared two forms of false-feedback, not operant conditioning of the EEG. Because these studies are highly cited and considered the gold standard in scientific rigor, a reappraisal of the evidence is urgently needed.
