Cette étude vise à analyser la dynamique de l’occupation des sols dans le bassin versant de la
rivière Kienké (Cameroun) et leurs effets sur les ressources en eau de surface. Il s’agit plus précisément de
détecter les changements de l’occupation des sols dans le bassin versant à partir des données satellitaires
multidates, et d’identifier les conséquences de la dynamique d’occupation des sols sur la qualité de l’eau de
surface ainsi que sur la gestion des ressources en eau dans le bassin versant de la Kienké. L’analyse des
changements spatio-temporels de l’occupation des sols a comporté les opérations suivantes : 1) traitement
des images satellitaires comparées à plusieurs dates (2001, 2009 et 2019), 2) élaboration des cartes
d’occupation des sols, 3) et estimation des superficies des classes d’occupation des sols. Les données sur
la qualité de l’eau ont été collectées à travers des prélèvements de cinq échantillons d’eau de la Kienké
analysés au laboratoire. Les résultats montrent une régression de 13 % du couvert forestier et des plans
d’eau au profit des zones anthropisées (palmeraies, tissus urbains, zone rurale, sol nu, etc.). Cette
dynamique est influencée par des facteurs d’ordre anthropiques à l’instar de la croissance démographique,
l’accroissement des activités économiques, l’exploitation forestière et l’expansion de l’agriculture. Ces
facteurs sont interdépendants et aucun d’eux ne peut être analysé séparément. Les résultats suggèrent
également que la qualité de l’eau de la Kienké se dégrade de l’amont vers l’aval, en raison de l’augmentation
des quantités d’eaux usées due à la croissance démographique, à l’accroissement de l’activité économique,
à l’expansion de l’agriculture et au rejet d’eaux usées sans aucun traitement.

Digital Food and the Innovation of Gastronomic Tourism
Authors: Hjalager Anne-Mette
Published: August 2022

This article examines 17 examples of digital food in the tourism sector. Innovative digital transformation includes, for example, robots, integrated data-based servicescapes in restaurants, platform solutions that enhance community creation and sustainability, augmented and virtual reality (AR and VR), smart destinations, etc. The COVID-19 pandemic has stimulated a deeper tech-supported division of labor in the food sector, and transitions seem to be viable after the normalization of social life. Digital transformations may have come late in the food sector. However, the way that solutions are constantly modified converges with general logics in tech sector—that is, monopolistic tendencies, rapid accumulation, and planned upscaling and internationalization. Digital solutions receive widespread and positive appreciation for their ability to enhance creativity and experience value. Critical voices regarding new social practices are still limited, as are traces of e-fatigue. The article recommends that future studies embark on social, economic, and environmental discourses in greater depth. Critical theory will be helpful to guide the mapping of how digital food innovation can liberate, mobilize, and empower tourists and residents.

This paper presents a novel work on localization of transmitters using triangulation with sensors at fixed positions. This is achieved when three or more sensors cover the whole area, a factor which enables the system to perform localization via triangulation. The network needs to keep a high detection rate which, in most cases, is achieved by adequate sensor coverage. Various tests using various grids of sensors have been carried out to investigate the way the system operates in different cases using a lot of transmitters. Detection complexity is tackled by finding the optimal detecting sensor radius in order for the network to continue operate normally. The coverage quality changes in the area of interest and the network is able to detect new transmitters that might enter the area of interest. It is also shown that as the number of transmitters increases the network keeps its high performance by using additional groups of sensors in a sub-region area of that of interest. This way, even when the network is saturated by many transmitters in one region, new transmitters can still be detected.

A logistic regression-based model to predict ICU mortality: problems and solutions
Authors: Luchinin A. S. , Lyanguzov A. V.
Published: August 2022

The ICU department’s mortality rate is one of the most important indicators of quality of care. Based on real clinical data, we attempted to build a prognostic model for patients with blood diseases in the ICU with using of the logistic regression method. The study included 202 patients in total. The median age was 57 (19–82) years. There were 112 (55 %) males and 90 (45 %) females. The statistical analysis was performed by using R software, version 3.4.2. The absolute risk of death (mortality rate) was 67 from 202 (33 %), odds — 0.496. The odds of death in ICU grow up to ~20 times if the patient has a Glasgow score of less than 15. Also, the odds of death increase by 1.3 and 11 times of PLT, or serum total protein level decreases by 2 times accordingly. Our model for “high-risk of death” detection classified patients in the test dataset with 0.816 accuracy (95 % CI 0.679–0.912), with sensitivity 0.823, and specificity 0.80. Despite the simple method for data analysis, we got a pretty accurate model of mortality prognosis with efficacy more than qSOFA and MEWS scales. Research in this area should continue.
External control during RWD/RWE research: a methodological approach
Authors: Zhuravkov A. A. , Kolbin A. S.
Published: August 2022

At the moment, randomized controlled trials (RCTs) are the gold standard for providing evidence of the effectiveness and safety of medicines. If it is impossible to randomize and create an internal control group, alternative methods of collecting evidence are used, for example, the use of so-called external control groups created, among other things, based on real world data (RWD). The increase in the number of studies using RWD and external control is clearly visible in oncology, where there are problems with randomization classically. Meanwhile, this trend is of concern and requires a better understanding of the acceptability of using external control groups and validation of RWD.

Introduction. Lung cancer (LC) is one of the leading causes of mortality in Russia and in all other the  world. Late detection of LC is a healthcare system issue because of most of patients are asymptomatic. Aim. The aim of    the study was to analyze the structure of healthcare resources in the group of patients with non-small cell LC (NSCLC) in  St. Petersburg. Materials and methods. The database of electronic medical records was created by combining the information from National cancer register and governmental medical insurance system, which included the patient with NSCLC diagnosed between 2011 and 2020 years. The data about the high technology medical services received by patients was added in the database as well. Results. None of the existing electronic medical records system is able to make visible all  the medical services received by a specific patient. The combined database gives the possibility to follow-up the history of around 8000 patients with NSCLC in St. Petersburg. Conclusions. When building the hospital model of the NSCLC patient aiming the rational planning of healthcare resources the stage of the disease is the most important because it is strongly linked with the healthcare resources provided to the patient.

Authors: Krysanov I. S. , Krysanova V. S. , Ermakova V. Yu.
Published: August 2022

Objectives. Cardiovascular diseases (CVD) are one of the leading causes of death worldwide, including Russia. According to the data obtained from the ESSE-RF study, the most common risk factor for the development of CVD is high level of cholesterol. At the same time, among drugs that lower cholesterol levels, statins are the most studied. The main aim of the study was to conduct a retrospective pharmacoepidemiological study to assess the effect of hypolipidemic therapy on overall and cardiovascular mortality in the regions of the Russian Federation.Methods. At the first stage, the indicators of population, cardiovascular and overall mortality in 2012–2018 were analyzed for 84 subjects of the Russian Federation. The time period of the analysis is determined by the timing of the implementation of the Federal project "Combating Cardiovascular Diseases". Next, we analyzed the frequency of prescribing lipid-lowering therapy in high doses in 84 regions of the Russian Federation in 2014– 2018, according to IMS Health for 2 market segments (preferential and hospital). The number of patients receiving high-dose statins (HDS) (atorvastatin 40 and 80 mg, rosuvastatin 20 and 40 mg) was calculated based on sales volumes in natural terms.Results. Based on the analysis of cardiovascular mortality, all 84 regions of the Russian Federation were divided into 3 groups: high, medium and moderate mortality. In the high-mortality group, HDS consumption per patient averaged 4.45 patients per 100,000 population, in the moderate-mortality group, 19.39 patients, and in the moderate-mortality group, 21.51 patients.Conclusions. The results of the study showed that there is a relationship between the frequency of HDS use and cardiovascular mortality in the regions of the Russian Federation. These results may indicate the effectiveness of lipid-lowering therapy in real practice.

We have reviewed the first year of observations of the Solar X-ray Monitor (XSM) on board Chandrayaan-2 and the available multiwavelength observations to complement the XSM data, focusing on the Solar Dynamics Observatory AIA and Hinode XRT and EIS observations. XSM has provided disk-integrated solar spectra in the 1–15 keV energy range, observing a large number of microflares. We present an analysis of multiwavelength observations of AR 12759 during its disk crossing. We use a new radiometric calibration of EIS to find that the quiescent active region (AR) core emission during its disk crossing has a distribution of temperatures and chemical abundances that does not change significantly over time. An analysis of the XSM spectra confirms the EIS results and shows that the low first ionization potential (FIP) elements are enhanced compared to their photospheric values. The frequent microflares produced by the AR did not affect the abundances of the quiescent AR core. We also present an analysis of one of the flares it produced, SOL2020-04-09T09:32. The XSM analysis indicates isothermal temperatures reaching 6 MK. The lack of very high-T emission is confirmed by AIA. We find excellent agreement between the observed XSM spectrum and the one predicted using an AIA DEM analysis. In contrast, the XRT Al-poly/Be-thin filter ratio gives lower temperatures for the quiescent and flaring phases. We show that this is due to the sensitivity of this ratio to low temperatures, as the XRT filter ratios predicted with a DEM analysis based on EIS and AIA give values in good agreement with the observed ones.
Testing a New Model of Embedded Protostellar Disks against Observations: The Majority of Orion Class 0/I Disks Are Likely Warm, Massive, and Gravitationally Unstable
Authors: Xu 许 Wenrui 文睿
Published: August 2022

We formulate a parameterized model of embedded protostellar disks and test its ability to estimate disk properties by fitting dust-continuum observations. The main physical assumptions of our model are motivated by a recent theoretical study of protostellar disk formation; these assumptions include that the disk should be marginally gravitationally unstable, and that the dominant dust heating mechanism is internal accretion heating instead of external protostellar irradiation. These assumptions allow our model to estimate reliably the disk mass even when the observed emission is optically thick and to determine self-consistent disk (dust) temperatures. Using our model to fit multiwavelength observations of 163 disks in the VANDAM Orion survey, we find that the majority (57%) of this sample can be fit well by our model. Using our model, we produce new estimates of Orion protostellar disk properties. We find that these disks are generally warm and massive, with a typical star-to-disk mass ratio

Solar Magneto-seismology of a Magnetic Slab in an Asymmetric Magnetic Environment
Authors: Zsámberger Noémi Kinga , Erdélyi Róbert
Published: August 2022

Diagnosing the solar atmospheric plasma remains one of the major challenges in solar physics. In recent years, new methods have been developed to apply the powerful concept of solar magneto-seismology (SMS) to obtain information about plasma parameters in solar structures guiding magnetohydrodynamic (MHD) waves that would otherwise be difficult to measure. This paper uses the Cartesian model of a magnetic slab placed in an asymmetric magnetic environment to generalize recently discovered SMS techniques. Utilizing the fact that the asymmetric environment changes the character of the classical kink and sausage eigenmodes, we describe two spatial seismology methods built upon this mixed character of quasi-sausage and quasi-kink modes. First, we present the amplitude ratio technique, which compares the oscillation amplitudes measured at the two boundaries of the slab, and we provide expressions to estimate the internal Alfvén speed in the thin slab and in the incompressible plasma approximations. The second main technique relies on the changed distribution of wave power throughout the slab under the effect of waveguide asymmetry. This minimum perturbation shift technique is then also utilized to provide Alfvén speed estimates that depend on the plasma and magnetic parameters of the environment, as well as the measured slab width and oscillation frequency. Finally, we perform a brief investigation of how the amplitude ratio and the minimum perturbation shift depend on the different sources of waveguide asymmetry, and illustrate our findings with numerical results.

Authors: Syafri Suryati , Husni Elidahanum , Wafiqah Nurul , Ramadhan Fitrah , Ramadani Sovia , Hamidi Dachriyanus
Published: August 2022

BACKGROUND: Citrus species produce essential oils (EOs) containing various chemical components that show many pharmacological activities.

AIM: The purpose of this study is to evaluate the chemical content and antimicrobial activity of EO extracted from fruit peels and leaves of Citrus x aurantifolia (“Asam sundai”) and Citrus aurantifolia (lime EOs extracted from fruit peels and leaves).

METHODS: The EO was extracted by the hydrodistillation method. The chemical content was determined using gas chromatography in tandem with mass spectroscopy (GC-MS). Antibacterial activity was performed using broth microdilution method, while proliferation of fibroblast cell was carried out using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay.

RESULTS: The main constituent of the EO of “asam sundai” peel (MAKS) and lime peel (MAKN) was I-limonene, while the EO of “asam sundai” leaves (MADS) was γ-terpinene. MAKN EOs showed stronger antibacterial activity than MAKS and MADS with minimum inhibitory concentration values of 3.12 mg/ml against S. aureus, MRSA, and Pseudomonas aeruginosa and 6.25 mg/ml for Streptococcus mutans and Escherichia coli. Meanwhile, the highest fibroblast cell proliferation activity showed by MAKS EO at concentrations of 10, 1, and 0.1 g/ml with a percentage of the proliferation of more than 100%.

CONCLUSION: It can be concluded that the different species of citrus have different chemical compositions and different biological activities.

People are involved with the collection and curation of all biodiversity data, whether they are researchers, members of the public, taxonomists, conservationists, collection managers or wildlife managers. Knowing who those people are and connecting their biographical information to the biodiversity data they collect helps us contextualise their scientific work. We are particularly concerned with those people and communities involved in the collection and identification of biological specimens. People from herbaria and natural science museums have been collecting and preserving specimens from all over the world for more than 200 years. The problem is that many of these people are only known by unstandardized names written on specimen labels, often with only initials and without any biographical information. The process of identifying and linking individuals to their biographies enables us to improve the quality of the data held by collections while also quantifying the contributions of the often underappreciated people who collected and identified these specimens. This process improves our understanding of the history of collecting, and addresses current and future needs for maintaining the provenance of specimens so as to comply with national and international practices and regulations.

In this talk we will outline the steps that collection managers, data scientists, curators, software engineers, and collectors can take to work towards fully disambiguated collections. With examples, we can show how they can use these data to help them in their work, in the evaluation of their collections, and in measuring the impact of individuals and organisations, local to global.

Morinda citrifolia fruit (Noni) has been used as a folk medicine in several countries. Noni possessed various pharmacological activities such as; anticancer, antidiabetic, antihypertensive, antarthritic, and antioxidants. The present study evaluated pharmacognostic properties, profiling of active constituent through High-Performance Thin Layer Chromatography (HPTLC) and Liquid Chromatography-High Resolution Mass Spectrometer (LC-HRMS) run for quantitative and qualitative phytochemical analysis and determining angiotensin-converting enzyme (ACE) inhibitor activity of Noni from three different locations. The physicochemical parameters of crude drugs and extracts met the requirement of Indonesian Herbal Pharmacopeia. Total phenol content was 2.16-3.08 mg GAE/g extract and total flavonoid content was 0.11 - 1.58 mg QE/g extract. HPTLC analysis revealed that scopoletin content in Noni was in the range of 0.44 - 0.51%. The results were also corresponding well with LC-HRMS fingerprint analysis. In addition, Noni fruit extract from Bogor potential exhibited activity in inhibiting ACE with an IC50 value of 206.26 µg/mL.
Life history observations of the Illinois state endangered Enigmatic Cavesnail, Fontigens antroecetes (Hubricht, 1940) made under simulated cave conditions
Authors: Weck Robert G.
Published: August 2022

The Enigmatic Cavesnail, Fontigens antroecetes (Hubricht, 1940), is a cave adapted hydrobioid snail listed as state endangered in Illinois. It is known from only one cave in Illinois, Stemler Cave, and from several caves in the eastern Ozark ecoregion of Missouri. Little is known about the snail’s reproductive habits, embryological development, or growth rates. I attempted to gain basic life history information by breeding Enigmatic Cavesnails under simulated cave conditions in the laboratory. Six adult snails were collected from Stemler Cave and held in aerated containers of cave water with one or two cobbles from the cave stream. Containers of snails were housed in incubators set at the average cave water temperature of 13 °C. The snails produced 49 embryos in captivity over the course of 34 weeks. Eggs were deposited singly, attached to the underside of rocks within small pits or crevices. Nearly 82% of embryos developed to hatching. Mean estimated development time of embryos was 70.7 days. Survival of hatchling snails was poor. Limited data available from surviving hatchling snails suggests slow growth rates. The process was replicated with nine Enigmatic Cavesnails collected from Cliff Cave in St. Louis County MO. Captive Cliff Cave snails produced 34 embryos over 46 weeks and varied from the Stemler population in their oviposition behavior, with a majority of eggs deposited on the top surface of rocks. Cliff Cave snail embryos also had longer mean estimated development times (82.17 days).
Géographies de la spéculation et urbanisation du capital dans le Sud Global : une perspective à partir de Phnom Penh au Cambodge
Authors: Fauveaud Gabriel
Published: August 2022

Cet article analyse la manière dont les stratégies de développement urbain conditionnent et exacerbent la spéculation immobilière à Phnom Penh, la capitale du Cambodge. Partant d’une analyse de la littérature en études urbaines critiques traitant des enjeux de la spéculation immobilière, l’article propose de la considérer non pas comme un mode spécifique d’accumulation du capital, mais plutôt comme un spectre de pratiques et de stratégies qui conditionnent la production d’espaces urbains. À partir de trois études de cas, l’article analyse ensuite le rôle des condominiums, des projets multifonctionnels et des grands projets urbains dans l’évolution des stratégies spéculatives. En décortiquant les stratégies de développement, de gestion et de vente de ces projets, quatre mécanismes de la spéculation immobilière sont identifiés : l’urbanité spéculative, la fluidification et la temporalisation des investissements, la territorialisation de la spéculation et le développement de plateformes territoriales d’investissement. Ces mécanismes dessinent finalement les contours de « géographies de la spéculation » révélatrices de processus spatiaux et territoriaux qui participent de la circulation, de l’ancrage et de la valorisation des flux de capitaux immobiliers dans des marchés immobiliers du Sud Global en cours de financiarisation.
La pacification : un legs impérial hybride par-delà les décolonisations
Authors: Klein Jean-François
Published: August 2022

Le but de cet article est de montrer comment dans toutes les guerres dites de pacification, notamment lors des conflits de décolonisations du second xx e  siècle, mais, aussi, dans le cadre de conflits beaucoup plus récents, Vietnam, Afghanistan ou Irak, ces doctrines héritent d’un passé colonial proche, directement issu des entreprises impériales occidentales et japonaises du xix e . Il s’agit aussi de mettre en exergue, notamment, la doctrine française dite de « pacification », toujours attribuée dans l’historiographie à Gallieni et Lyautey, mais dont le véritable penseur fut Théophile Pennequin. Une doctrine qui passa le cap de la Première Guerre mondiale, s’hybrida et circula de façon trans-impériale et transnationale.
Les deux traités de la personne. Locke et l’idée de propriété de soi
Authors: Authier Raphaël
Published: August 2022

Si la notion de personne intervient de façon décisive, chez Locke, dans deux parties du corpus, ces deux usages ont souvent été considérés comme sans rapport l’un à l’autre. Nous tentons de montrer au contraire qu’entre le traité de l’identité personnelle (au chapitre 27 du livre II de l’ Essai sur l’entendement humain ) et le chapitre sur la propriété du Second traité du gouvernement , des similarités suffisantes existent pour qu’on puisse conclure à l’existence d’une même théorie de l’individu et de la personne, à l’œuvre dans la perspective épistémique et métaphysique, et dans la perspective sociale et politique. C’est à chaque fois l’idée de propriété de soi et la notion d’appropriation qui s’avère décisive, aussi bien pour comprendre le rapport de la conscience à ses contenus de pensée que pour comprendre le rapport de l’individu aux choses matérielles. Cette lecture permet alors de défendre, contre l’hypothèse d’une dualité irréductible de sens, la thèse d’une cohérence de la notion de propriété chez Locke.
Hydrogeochemistry and groundwater quality assessment in a municipal solid waste landfill (central Italy)
Authors: Barbieri Maurizio , Boschetti Tiziano , Sappa Giuseppe , Andrei Francesca
Published: August 2022

Municipal solid waste landfills leachate can cause serious environmental issues for groundwater quality. Therefore, the application of environmental tracing methods to identify groundwater contamination by municipal solid waste landfills leachate is significant. Hydrogeochemical evaluations to trace municipal solid waste landfills leachate are usually carried out. The study was carried out at a landfill in central Italy (Umbria). Samples of leachate and groundwater have been analyzed to evaluate the impact of leachates on groundwater through the comparison of their hydrogeochemical nature. Parameters like pH, Temperature (T), Electrical Conductivity (EC), redox potential (Eh) and Chemical Oxygen Demand (COD) were also measured in situ using digital instruments. Hydrogeochemical data (Na+, K+, Mg2+, Ca2+, SO42−, HCO3−, Cl−, NO3−), ionic ratios and geochemical correlations were used to confirm the processes that govern the chemistry of the spring water and to identify leachate contamination phenomena. In fact, the main geochemical diagrams (Langelier-Ludwig, Piper, Schoeller) confirm the leachate contamination in a groundwater sample. In particular, the Piper diagram shows that a sample is in Na+ – Cl- – HCO3- mixing zone, indicating a possible influence of the leachate on groundwater chemistry. As a matter of fact, some correlations between major elements, such as Cl- versus Na+ and Cl- versus HCO3-, confirm that the leachate in this study area is highly enriched in Cl- and HCO3- due to wastes dissolution and degradation processes. Further, the assessment of K+/Mg2+ ratio also confirms the presence of a sample heavily impacted from leachate contamination. These results indicate that also one basic hydrogeochemical study can be useful for fingerprinting the leachate pollution for groundwater samples.

Published: August 2022

The main motive of this work is to introduce a numerical investigation for the one and two-dimensional (1D/2D) Chaplygin gas model. Namely, we developed the non homogeneous Riemann solver (NHRS) method to solve these models. After discussing the Chaplygin gas models and the numerical scheme, various 1D and 2D test problems are introduced. In order to complete the numerical investigation in a completely unified way, Rusanov scheme, modified Lax-Friedrichs and analytical solution are compared with NHRS scheme in 1D case. The acquired results clarify the high resolution of the NHRS technique. The NHRS technique is efficacious and robust. Finally, our study displays that the NHRS scheme is a very powerful tool to solve many other models arising in applied science.

Published: August 2022

In this manuscript, we introduce a three dimension metric type spaces so called $ J $-metric spaces. We prove the existence and uniqueness of a fixed point for self mappings in such spaces with different types of contractions. We use our result to prove the existence and uniqueness of a solution of the following fractional differential equations such as

   \begin{document}$ \mathcal{(P)}:\left\{ \begin{array}{ccl} D^{\lambda}x(t) & = & f(t,x(t)) = Fx(t) \;{\rm{ if }}\; t\in I_0 = (0,T] \\ x(0) & = & x(T) = r \\ \end{array} \right\} . $\end{document}

Moreover, we present other applications to systems of linear equations and Fredholm type integral equation.
On the application of $ G_\alpha $ integral transform to nonlinear dynamical models with non-integer order derivatives
Authors: Nuruddeen Rahmatullah Ibrahim , Akbar Yasir , Kim Hwajoon
Published: August 2022

The current study uses an essential and integrated form of Laplace-type integral transform coupled with the Adomian's approach to study nonlinear evolution equations endowed with non-integer derivatives. More so, of particular interest here is to demonstrate the application of this transform to a wider class of nonlinear problems. Three test models have been examined by the presented method, and their closed-form solutions have been reported iteratively. Lastly, the variational effect of the non-integer order derivatives on the evolution of these models has been studied via the two and three-dimensional depictions.
Dual closed loop AUV trajectory tracking control based on finite time and state observer

Published: August 2022

The three-dimensional trajectory tracking of AUV is an important basis for it to complete its task. Due to many uncertain disturbances such as wind, wave and current on the sea, it is easy to cause problems such as slow convergence speed of the controller and saturation of the controller output in the three-dimensional trajectory tracking control of AUV. And the dynamic uncertainty of AUV's own model will have a great negative impact on AUV's trajectory tracking control. In order to solve the problem of slow convergence speed of the above controller, the finite time control method is introduced into the designed position controller. In order to solve the problem of AUV controller output saturation, an auxiliary dynamic system is designed to compensate the system control output saturation. In order to solve the uncertainty of AUV model, a reduced order extended observer is designed in the dynamic controller. It can observe the motion parameters of AUV at any time, and compensate the uncertainty of model uncertainty and external environment disturbance in real time. The control method in this paper is simulated in a three-dimensional model. The experimental results show that the convergence speed, control accuracy, robustness and tracking effect of AUV are higher than those of common trajectory tracker. The algorithm is loaded into the "sea exploration Ⅱ" AUV and verified by experiments in Suzhou lake. The effect of AUV navigation basically meets the task requirements, in which the mean value of pitch angle and heading angle error is less than 8 degrees and the mean value of depth error is less than 0.1M. The trajectory tracker can better meet the trajectory tracking control needs of the AUV.
