    Resonant Schr\"odinger Cat States in Circuit Quantum Electrodynamics

    Full text link
    We propose a fast scheme to generate Schr\"odinger cat states in a superconducting resonator using a continuously driven qubit without resorting to the dispersive regime, two-photon drives, or engineered two-photon dissipation. We provide analysis for when the qubit is on and off resonance from the drive. We extend our analysis to account for a third level in a weakly-anharmonic qutrit. We also discuss the case of a strongly-anharmonic qutrit. Throughout the paper, we corroborate our analytical results with numerical simulations in the presence of energy relaxation and dephasing of the qubit and resonator using realistic experimental parameters.Comment: 14 pages, 6 figures.

    The objectives of this paper are to elicit the perception of contracting parties regarding building information modelling (BIM), the most important safety-related applications of BIM and the barriers to adopting BIM in the local construction industry. Data for this study were collected through a questionnaire survey. A total of 75 questionnaires were randomly distributed to contractors, owners and consultants, and 37 were returned, representing a 49% response rate. The findings indicated that 33% of the respondents had no knowledge of the concept of BIM, 28% of the respondents’ organizations are not using BIM and if used it was implemented to a limited extent. The results indicated that ‘hazard identification and minimization’ and ‘safety training and education’ are the most important safety-related applications provided by BIM tools to improve safety performance in construction.

    Expectant management of a heterotopic interstitial pregnancy - a case report

    Get PDF
    Heterotopic pregnancy is the simultaneous occurrence of two pregnancies at two different implantation sites, mostly intrauterine and extrauterine sites. An interstitial ectopic pregnancy as part of a heterotopic pregnancy is very rare. This report highlights the case of a 40-year-old woman with heterotopic pregnancy who had conceived via assisted reproductive technology. The patient had an interstitial ectopic pregnancy and a viable intrauterine pregnancy. She was treated expectantly and had cesarean delivery of the intrauterine pregnancy at 38 weeks of gestation. Although management options for heterotopic pregnancies include surgical and medical, it may be reasonable to consider expectant management for select cases while weighing risks. In such cases, close monitoring of symptoms and serial ultrasound examinations should be standard

    Dynamic in vitro gastric digestion behaviour of camel milk

    Get PDF
    This study investigated the dynamic in vitro gastric digestion behaviour of camel milk. Coagulum that was retainable in the stomach was not formed during the digestion of camel milk, whereas bovine milk reconstituted to the same protein concentration (2.9%, w/w) underwent pronounced gastric coagulation into structured clots. During early digestion, the camel milk formed small particles, resulting from its weak coagulation, that were preferentially emptied from the stomach. These particles became more compact and spherical in the first hour of digestion and then gradually decreased in size. Protein analysis indicated that the main camel milk proteins were digested in the order αS1-casein > β-casein > α-lactalbumin, which may have been modulated by the decreasing pH during the dynamic gastric digestion. This unique coagulation behaviour of camel milk resulted in its rapid gastric digestion and emptying, which may have nutritional implications.fals

    Invited review: Camel milk and gut health-Understanding digestibility and the effect on gut microbiota.

    Get PDF
    Camel milk (CM), known for its immune-regulatory, anti-inflammatory, antiapoptotic, and antidiabetic properties, is a natural healthy food. It is easily digestible due to the high levels of β-casein and diverse secreted antibodies, exhibiting superior antibacterial and antiviral activities compared with bovine milk. β-casein is less allergic and more digestible because it is more susceptible to digestive hydrolysis in the gut; therefore, higher levels of β-casein make CM advantageous for human health. Furthermore, antibodies help the digestive system by destroying the antigens, which are then overwhelmed and digested by macrophages. The connection between the gut microbiota and human health has gained substantial research attention, as it offers potential benefits and supports disease treatment. The gut microbiota has a vital role in regulating the host's health because it helps in several biological functions, such as protection against pathogens, immune function regulation, energy harvesting from digested foods, and reinforcement of digestive tract biochemical barriers. These functions could be affected by the changes in the gut microbiota profile, and gut microbiota differences are associated with several diseases, such as inflammatory bowel disease, colon cancer, irritable bowel disorder, mental illness, allergy, and obesity. This review focuses on the digestibility of CM components, particularly protein and fat, and their influence on gut microbiota modulation. Notably, the hypoallergenic properties and small fat globules of CM contribute to its enhanced digestibility. Considering the rapid digestion of its proteins under conditions simulating infant gastrointestinal digestion, CM exhibits promise as a potential alternative for infant formula preparation due to the high β-/αs-casein ratio and protective proteins, in addition to the absence of β-lactoglobulin.fals

    This is the final version. Available from MDPI via the DOI in this record. Data Availability Statement: The original data presented in the study are openly available at https://wdsa-ccwi2024.it/battle-of-water-networks/ (accessed on 13 March 2024).Relationships between water demand, pressure, and leakage highlight the need for accurate supply to match demand. This study addresses the challenges of forecasting short-term water demand and was part of the Battle for Water Demand Forecasting competition involving 10 real-world District Metered Areas in Italy. A nine-layer convolutional neural network model was proposed that considers demand from previous time steps, time of the day, weather conditions, day type, and other deterministic temporal factors to predict water demand. Bayesian optimization was used for hyperparameter tuning. The model can predict and forecast short-term water demand with reasonable accuracy

    Gaps between paediatric and psychiatric surveillance systems: Rates of reporting in joint studies

    Get PDF
    \ua9 The Author(s), 2025. Published by Cambridge University Press on behalf of Royal College of Psychiatrists.Aims and method The British Paediatric Surveillance Unit of the UK Royal College of Paediatrics and Child Health contacts participating consultant paediatricians each month to survey whether particular rare conditions or events have been seen in their services. This national surveillance of rare paediatric events has allowed a large amount of research into multiple paediatric conditions. In 2009, the Royal College of Psychiatrists established a similar system - the Child and Adolescent Psychiatry Surveillance System (CAPSS) - to survey consultant psychiatrists in UK and Ireland. Since many conditions involve mental and physical health features, seven studies have been run using reporting to both systems, with simultaneous surveillance across both paediatricians and psychiatrists. Given the desire by policymakers, commissioners and clinicians for well-integrated physical and mental healthcare (\u27joined-up working\u27), and if the surveillance systems were functioning well, the CAPSS Executive expected high rates of parallel reporting of individual patients to the two systems. The current study synthesises the rates of parallel reporting of cases to those two systems. We assimilate rates of parallel reporting across the seven studies using figures that have already been published, and by contacting contributing research groups directly where the relevant figures are not currently published. No new primary data were collected. Results Of the 1211 confirmed cases, 47 (3.9%) were reported by both psychiatrists and paediatricians. No parallel reporting occurred in four of the seven studies. Clinical implications Our findings raise questions about whether joined-up working in mental and physical healthcare is happening in practice. Research into challenges to obtaining comprehensive surveillance will help epidemiologists improve their use of surveillance and control for biases

    Assessment of Yeasts as Potential Probiotics: A Review of Gastrointestinal Tract Conditions and Investigation Methods

    Get PDF
    Probiotics are microorganisms (including bacteria, yeasts and moulds) that confer various health benefits to the host, when consumed in sufficient amounts. Food products containing probiotics, called functional foods, have several health-promoting and therapeutic benefits. The significant role of yeasts in producing functional foods with promoted health benefits is well documented. Hence, there is considerable interest in isolating new yeasts as potential probiotics. Survival in the gastrointestinal tract (GIT), salt tolerance and adherence to epithelial cells are preconditions to classify such microorganisms as probiotics. Clear understanding of how yeasts can overcome GIT and salt stresses and the conditions that support yeasts to grow under such conditions is paramount for identifying, characterising and selecting probiotic yeast strains. This study elaborated the adaptations and mechanisms underlying the survival of probiotic yeasts under GIT and salt stresses. This study also discussed the capability of yeasts to adhere to epithelial cells (hydrophobicity and autoaggregation) and shed light on in vitro methods used to assess the probiotic characteristics of newly isolated yeasts
