Abstract. Strategies used by marine vertebrates to regulate their body temperature can result in local variations, and the knowledge of these regional heterothermies is crucial for better understanding the thermophysiologies of extant and extinct organisms. In order to investigate regional heterothermy in vertebrates, we analysed the oxygen isotope composition of phosphatic skeletal elements (δ18Op) of two poikilothermic (Atlantic bluefin tuna and swordfish) and three homeothermic endotherms (dolphins). We observed a consistent link between δ18Op variations and temperature heterogeneities recorded by classical methods. Our δ18Op data indicate that: (i) bone hydroxyapatite of the axial skeleton of dolphins mineralize at a warmer temperature than that of the appendicular one, (ii) the skull is the warmest body region in swordfish, and (iii) Atlantic bluefin tuna possesses high body temperature in the skull and visceral mass region. These results demonstrate the possibility of tracking regional heterothermies in extant marine vertebrates using the δ18Op, paving the way to direct assessment of thermophysiological specificities of both living and extinct vertebrates. From a paleoenvironmental perspective, the significant observed δ18Op variability questions the use of some taxa or random skeletal elements for the reconstruction of paleoceanographic parameters such as seawater temperature and δ18O.

Abstract. A better understanding of ENSO dynamics is essential for modelling future climate change and its impacts on the ecosystems and lives of the inhabitants of the tropical Pacific islands, which face considerable environmental risk in the coming decades. This study reconstructs past ENSO dynamics using a multi-proxy approach applied to a stalagmite from Niue Island that covers the period 6.4–5.4 ka BP. δ18O and δ13C, trace-element concentrations and image analysis are linked to an age-depth model constrained by eight U/Th dates and a complete lamina count. Principal component analysis of the proxy time series reveals hydrological changes at seasonal scale that are expressed in differential stalagmite lamina growth and geochemical characteristics. Increased concentrations of host-rock derived elements (Mg/Ca and U/Ca) and higher δ18O and δ13C values are observed in the dark, dense calcite laminae that are deposited during the dry season, whereas during the wet season higher concentrations of soil derived elements (Zn/Ca, Mn/Ca) and higher δ18O and δ13C values are found in pale, porous calcite laminae. Greyscale intensity values measured along the stalagmite growth axis are used here as an indicator of colour and density changes of the alternating laminae, allowing for the construction of a further seasonality record which expresses the contrast between wet and dry seasons. The multi-proxy record from Niue shows seasonal cycles associated with hydrological changes controlled by the South Pacific convergence zone. Wavelet analysis of the greyscale record reveals that ENSO was continuously active during the depositional period, with two weaker intervals at 6–5.9 and 5.6–5.5 ka BP. ENSO activity is also observed in the seasonality record, but muted periods are more prolonged, and intervals of significant ENSO-band power are more episodic. Recurrence analysis of nonlinear behaviour shows the influence that ENSO activity exerts on seasonality patterns and allows us to quantify the predictability of the climate system. Our results suggest that recurrence in the seasonal cycle of rainfall was reduced during periods when ENSO activity was stronger, pushing the system towards stochastic conditions. The tipping points from stochastic to predictable conditions may represent transitions in the Tropical Pacific mean state.
Characterizing natural variability in complex hydrological systems using Passive Microwave based Climate Data Records: a case study for the Okavango Delta

Published: January 2022

Abstract. The Okavango river system in southern Africa is known for its strong interannual variability of hydrological conditions. Here we present how this is exposed in surface soil moisture, land surface temperature, and vegetation optical depth as derived from the Land Parameter Retrieval Model using an inter-calibrated, long term, multi-sensor passive microwave satellite data record (1998–2020). We also investigate how these interannual variations relate to state-of-the-art climate reanalysis data from ERA5-Land. We analyzed both the upstream river catchment and the Okavango Delta, supported by independent data records of discharge measurements, precipitation and vegetation dynamics observed by optical satellites. The seasonal vegetation optical depth anomalies have a strong correspondence with MODIS Leaf Area Index (correlation catchment: 0.74, Delta: 0.88). Land surface temperature anomalies derived from passive microwave observations match best with those of ERA5-Land (catchment: 0.88, Delta: 0.81), as compared to MODIS nighttime LST (catchment: 0.70, Delta: 0.65). Although surface soil moisture anomalies from passive microwave observations and ERA5-Land correlate reasonably well (catchment: 0.72, Delta: 0.69), an in-depth evaluation over the Delta uncovered situations where passive microwave satellites record strong fluctuations, while ERA5-Land does not. This is further analyzed using information on inundated area, river discharge and precipitation. The passive microwave soil moisture signal demonstrates a response to both the inundated area and precipitation. ERA5-Land however, which by default does not account for any lateral influx from rivers, only shows a response to the precipitation information that is used as forcing. This also causes the reanalysis model to miss record low land surface temperature values as it underestimates the latent heat flux in certain years. These findings demonstrate the complexity of this hydrological system and suggest that future land surface model generations should also include lateral land surface exchange. Also, our study highlights the importance of maintaining and improving climate data records of soil moisture, vegetation and land surface temperature from passive microwave observations and other observation systems.
Climate Bifurcations in a Schwarzschild Equation Model of the Arctic Atmosphere
Authors: Kypke Kolja L. , Langford William F. , Lewis Gregory M. , Willms Allan R.
Published: January 2022

Abstract. A column model of the Arctic atmosphere-ocean system is developed including the nonlinear responses of surface albedo and water vapor to temperature. The atmosphere is treated as a gray gas and the flux of longwave radiation is governed by the two-stream Schwarzschild equations. Representative carbon pathways (RCPs) are used to model carbon dioxide concentrations into the future. The resulting nine-dimensional two-point boundary value problem is solved under various RCPs and the solutions analyzed. The model predicts that under the highest carbon pathway, the Arctic climate will undergo an irreversible bifurcation to a warm steady state, which would correspond to an annually ice-free situation. Under the lowest carbon pathway, corresponding to very aggressive carbon emission reductions, the model exhibits only a mild increase in Arctic temperatures. Under the two moderate carbon pathways, temperatures increase more substantially, and the system enters a region of bistability where external perturbations could possibly cause an irreversible switch to a warm, ice-free state.
Storm track response to uniform global warming downstream of an idealized sea surface temperature front
Authors: Schemm Sebastian , Papritz Lukas , Rivière Gwendal
Published: January 2022

Abstract. The future evolution of storm tracks, their intensity, shape, and location, is an important driver of regional precipitation changes, cyclone-associated weather extremes, and regional climate patterns. For the North Atlantic storm track, Coupled Model Intercomparison Project (CMIP) data indicate a tripole pattern of change under the RCP 8.5 scenario. In this study, the tripole pattern is reproduced by simulating the change of a storm track generated downstream of an idealized sea surface temperature (SST) front under uniform warming on an aquaplanet. The simulated tripole pattern consists of reduced eddy kinetic energy (EKE) upstream and equatorward of the SST front, extended and poleward shifted enhanced EKE downstream of the SST front, and a regionally reduced EKE increase at polar latitudes. In the absence of the idealized SST front, in contrast, the storm track exhibits a poleward shift but no tripole pattern. A detailed analysis of the EKE and eddy available potential energy (EAPE) sources and sinks reveals that the changes are locally driven by changes in baroclinic conversion rather than diabatic processes. However, globally the change in baroclinic conversion averages to zero, thus the observed global EAPE increase results from diabatic generation. In particular, resolved-scale condensation plus parameterized cloud physics dominate the global EAPE increase followed by longwave radiation. Feature-based tracking provides further insight into cyclone life-cycle changes downstream of the SST front. Moderately deepening cyclones deepen less in a warmer climate, while strongly deepening cyclones deepen more. Similarly, the average cyclone becomes less intense in a warmer climate, while the extremely intense cyclones become more intense. Both results hold true for cyclones with genesis in the vicinity of the SST front and elsewhere. The mean cyclone lifetime decreases, while it increases for those cyclones downstream of the SST front. The mean poleward displacement between genesis and maximum intensity increases for the most intense cyclones, while averaged over all cyclones there is a mild reduction and the result depends on the definition of the displacement. Finally, the number of cyclones decreases by approximately 15 %. Aquaplanet simulations with a localized SST front thus provide an enriched picture of storm track dynamics and associated changes with warming.
Local-thermal-gradient and large-scale-circulation impacts on turbine-height wind speed forecasting over the Columbia River Basin
Authors: Liu Ye , Qian Yun , Berg Larry K.
Published: January 2022

Abstract. We investigate the sensitivity of turbine-height wind speed forecast to initial condition (IC) uncertainties over the Columbia River Gorge (CRG) and Columbia River Basin (CRB) for two typical weather phenomena, i.e., local-thermal-gradient-induced marine air intrusion and a cold frontal passage. Four types of turbine-height wind forecast anomalies and their associated IC uncertainties related to local thermal gradients and large-scale circulations are identified using the self-organizing map (SOM)
technique. The four SOM types are categorized into two patterns, each
accounting for half of the ensemble members. The first pattern corresponds
to IC uncertainties that alter the wind forecast through a modulating weather system, which produces the strongest wind anomalies in the CRG and CRB. In the second pattern, the moderate uncertainties in local thermal gradient and large-scale circulation jointly contribute to wind forecast anomaly. We analyze the cross section of wind and temperature anomalies through the gorge to explore the evolution of vertical features of each SOM type. The turbine-height wind anomalies induced by large-scale IC uncertainties are more concentrated near the front. In contrast, turbine-height wind anomalies induced by the local IC thermal uncertainties are found above the surface thermal anomalies. Moreover, the wind forecast accuracy in the CRG and CRB is limited by IC uncertainties in a few specific regions, e.g., the 2 m temperature within the basin and large-scale circulation over the northeast Pacific around 140∘ W.
A reference open-source controller for fixed and floating offshore wind turbines
Authors: Abbas Nikhar J. , Zalkind Daniel S. , Pao Lucy , Wright Alan
Published: January 2022

Abstract. This paper describes the development of a new reference controller framework for fixed and floating offshore wind turbines that greatly facilitates controller tuning and represents standard industry practices. The reference wind turbine controllers that are most commonly cited in the literature have been developed to work with specific reference wind turbines. Although these controllers have provided standard control functionalities, they are often not easy to modify for use on other turbines, so it has been challenging for researchers to run representative, fully dynamic simulations of other wind turbine designs. The Reference Open-Source Controller (ROSCO) has been developed to provide a modular reference wind turbine controller that represents industry standards and performs comparably to or better than existing reference controllers. The formulation of the ROSCO controller logic and tuning processes is presented in this paper. Control capabilities such as tip speed ratio tracking generator torque control, minimum pitch saturation, wind speed estimation, and a smoothing algorithm at near-rated operation are included to provide modern controller features. A floating offshore wind turbine feedback module is also included to facilitate growing research in the floating offshore arena. All of the standard controller implementations and control modules are automatically tuned such that a non-controls engineer or automated optimization routine can easily improve the controller performance. This article provides the framework and theoretical basis for the ROSCO controller modules and generic tuning processes. Simulations of the National Renewable Energy Laboratory (NREL) 5 MW reference wind turbine and International Energy Agency 15 MW reference turbine on the University of Maine semisubmersible platform are analyzed to demonstrate the controller's performance in both fixed and floating configurations, respectively. The simulation results demonstrate ROSCO's peak shaving routine to reduce maximum rotor thrusts by over 10 % compared to the NREL 5 MW reference wind turbine controller on the land-based turbine and to reduce maximum platform pitch angles by nearly 30 % when using the platform feedback routine instead of a more traditional low-bandwidth controller.

According to expeditionary and coastal monitoring studies carried out in 2019 and 2020, we analyzed the structure features and temporal variations of colored dissolved organic matter concentration in the Omega Bay field. It is shown that the structure of the analyzed parameter field in the Omega Bay is formed as a result of interactions in the system of local anticyclonic circulation that involves both Sevastopol seaside water, where its concentration is close to the natural normal, and water of the isolated apex part of the bay that experiences anthropogenic pressure. The field under consideration is well stratified in the apex of the bay and is characterized by poorly pronounced vertical stratification in the central and open marine part of the bay. The response to atmospheric and marine processes is traced in the field of colored dissolved organic matter concentration during the summer of 2020. It was revealed that rains and polluted water advection from the sea were accompanied by a noticeable increase in the concentration of the analyzed substance in the beach area of the bay. The opposite effect was observed during upwelling.

In what follows I have juxtaposed four pieces of autobiographical work which are given coherence, if at all, by the recurring themes of maps/mapping and exploration/naming. None of them is complete or therefore conclusive; they are work in progress directed at accounting for a life, but at a stage where many gaps remain, and many links are missing. To give just one example, there is allusion to my Primary schooling, but nothing about the two extraordinary teachers who provided it and are probably more responsible than Arthur Ransome’s novels for the life’s direction.

A mathematical model of a differential-rangefinder local positioning system has been developed, which in real time makes it possible to predict the working area of the system, taking into account the construction barriers of the emergency zone. The conditions of propagation of high-frequency signals, which determine the quality of positioning and the accuracy characteristics of the system, are taken into account. To simplify the simulation, a number of assumptions were made regarding the parameters of the obstacles and the conditions of radio wave propagation, which make it possible to simplify the prediction process. On the basis of the geometric criterion and the criterion of maximum removal, a modified geometry coefficient (zone coefficient) was obtained, which is proposed to be used as the basis for a mathematical forecasting model. Using this criterion, a computational algorithm and a program for operational forecasting of the working area of local positioning have been developed, which make it possible to take into account the influence of the number of beacons, the geometry of the system and the location of building barriers to the propagation of radio signals on the shape of the working area. In the process of modeling, both geometric and general physical laws of the formation of the field of radio navigation support were taken into account. A study of the operation of the modeling system was carried out in the presence of several radio beacons, in the absence and in the presence of several construction barriers within the emergency zone. The developed mathematical model makes it possible to calculate the size of the positioning zones with the determination of the boundary conditions for the reliability and accuracy of the navigation support of rescuers. Taking into account the process of predicting the impact of obstacles in the emergency zone on the type and size of the working area of the positioning system allows the head of emergency response to make the right management decision, ensure safe working conditions for rescuers and optimize emergency response.

The paper proposes and substantiates the approach to the location of fire hydrant kits in the plan of the building, which is one of the main areas of implementation of the required level of its fire protection system. It is determined that the location of fire hydrant kits is a must to ensure irrigation of each point of the room with the required number of jets, which affects the success of the use of internal fire water for firefighting. The parameters influencing the location and number of fire hydrant sets in the building are investigated. It is shown that when using fire hoses of maximum length, the radius of the fire hydrant set increases and their required number decreases accordingly. The diameter of the fire hose affects the water consumption obtained from the crane set and must be at least standard. It is shown that when choosing the number of fire hydrant sets, in addition to the characteristics of their equipment, it is necessary to take into account the design features of the room and the standard number of jets, which significantly affects the economic component. The principles of placement of the main and additional fire hydrant sets for different number of jets at each point of the room are investigated. Based on the analysis of parameters that affect the number of fire hydrant kits in the plan of the building, an approach to the placement of PAC on the principle of their reasonable sufficiency. The efficiency of the proposed approach to the placement of fire hydrant kits is established. Evaluation of the effectiveness of the proposed approach to the placement of fire hydrant kits showed that the rationale for the decision on the number of main and additional fire hydrant kits in the building allows to meet regulatory requirements for irrigation of each point of the room with the required number of jets. protection.

A network model of operational actions of emergency rescue teams in the elimination of the consequences of emergency situations in a graphical and mathematical representation has been developed. The use of the model makes it possible to plan or analyze the process of organizing operational actions of civil protection units, to manage the course of its implementation. This is relevant for the planned period of emergency response. The task of forming performers of individual works in the elimination of the consequences of emergency situations has been formulated. The essence of the task is reduced to the ability to choose from a variety of civil protection units the necessary performers and assign them to work. Moreover, upon the appointment, the entire complex of works was completed within a given deadline and with minimal costs. Formalization of the corresponding problem made it possible to bring it to the classical assignment problem, which is solved by Kuhn's method. The use of a dynamic pro-gramming algorithm made it possible to obtain an initial approximation of the solution of the problem, at which the cost of performing a complex of emergency rescue operations will be minimal. To optimize the network graph of operational actions by reducing the length of the critical path, a dynamic programming method is proposed. The research results are synthesized into an algorithm. The implementation of the algorithm is to consistently clarify the assignments of performers to work. This makes it possible to determine the minimum costs for the implementation of the rescue plan within a given time frame (if such a solution exists), as well as to estimate the minimum time for carrying out emergency rescue operations for a given set of possible performers.

Experimental studies on the occurrence of fire in a residential building depending on the conditions of its development. A model of the house was used for research, which allowed to clearly demonstrate the development of fire with a demonstration of its phenomena. It is determined that the development of a fire with limited access to oxygen occurs with the occurrence of fire phenomena such as rollover, flashover and backdraft, and with sufficient access to oxygen occurs normally. It is established that during the development of a fire first there is a phenomenon of rollover, due to the ignition of a layer of heated gases, then there is a flashover, characterized by a flash, and for backdraft, this phenomenon occurs due to a flash of unburned heated gases with a subsequent explosion. The temperature was measured using a FLIR K33 thermal imager during a fire. The obtained results show that the development of a fire with sufficient access of oxygen occurs before the maximum temperature in the room with its subsequent reduction due to fire extinguishing or supply of fire extinguishing agents to the fire. When a fire with limited access to oxygen develops, such phenomena as rollover, flashover and backdraft occur. The obtained measurement results during the research of fire development depending on its conditions are presented as photoregistration of images from the thermal imager and graphically. It is established that when the phenomenon of a flashover occurs, the flash point is 234 C, and when the backdraft phenomenon, the flash point of unburned heated gases with a subsequent explosion is 569 C. It has been experimentally determined that timely cooling of heated gases prevents fire. The obtained results of the conducted experimental researches allow to increase the level of professional skill of the personnel of fire and rescue divisions during carrying out operative actions on fire extinguishing in residential buildings.
Правовые позиции высших судов в сфере обеспечения и защиты конституционного права на охрану здоровья и репродуктивных прав

Предпринята попытка анализа правоприменительной практики в сфере обеспечения и защиты конституционного права на охрану здоровья и репродуктивных прав, иных конституционных прав и свобод и принципа гендерного равенства в деятельности высших судов ряда зарубежных стран. Неблагоприятная демографическая ситуация и проблемы ухудшения репродуктивного здоровья являются факторами, побуждающими государства закреплять репродуктивные права в качестве основных прав и свобод, гарантируемых конституцией. Об этом говорит и изменение позиций конституционных судов в тех странах, где репродуктивные права в конституции не провозглашены. В то же время многие государства становятся на позицию признания права на жизнь с момента зачатия, что зачастую приводит к ограничению тех или иных репродуктивных прав, в частности права на аборт и контрацепцию. Данный анализ представляет интерес в силу ограниченного количества дел подобной категории в практике российских судов и пока незначительного объема опыта отечественных юристов-практиков, которые бы позволили выявить наиболее важные проблемы в отечественном регулировании анализируемой сферы общественных отношений.

Ayurveda is an ancient science of India and helps the human body to keep fit while providing cures from indigenous plants, animal and mineral origin products for various ailments. In Ayurveda literature, Berberis aristata has been described as a major plant possess antidiarrheal, antimicrobial, antiprotozoal and antitrachoma activity and used in for several remedies including diarrhea, chronic rheumatism, jaundice, skin diseases, syphilis and urinary disorders. Berberis aristata contains photoactive constituents such as berberine, oxyberberine, berbamine, aromoline, a protoberberine alkaloid karachine, palmatine, oxycanthine and taxilamine and tannins, sugar, starch. The present study has been designed to develop a quality control protocol for the coded Ayurvedic drug by analyzing the reference standard of bioactive compound present in the formulation and respective ingredient. The Rf value of berberine chloride reference standard 0.05 was visible in test solution of Berberis aristata stem as well as in coded Ayurvedic drug extract and found comparable under UV 254 nm and 366 nm, respectively. The quantitative evaluation revealed the presence of berberine chloride in the coded Ayurvedic drug and Berberis aristata DC stem extract was 0.1261% and 5.3936%, respectively.

Published: January 2022

This research analyses the correlation that exists between fuzzy T-ABSO and fuzzy socle. To answer
this question, we define a new concept called, fuzzy socle T-ABSO submodules. Results showed many properties
that satisfied the new notion. In addition, we applied some algebra operations and found the relationship between
fuzzy T-ABSO and fuzzy socle -T-ABSO. We also investigated the structure of fuzzy socle T-ABSO sub- modules of
a module under fuzzy direct sum, homomorphic image and intersection. Moreover, the relation between fuzzy socle
T-ABSO sub-module and other types of fuzzy sub-module was presented. The implications of this study could be
used to define new concepts that depend on fuzzy socle T-ABSO concepts

The researcher employed multiple regression analysis to analyze the data. The results of the study revealed that there was a positive and significant relationship between technical knowledge, provider responsiveness, effective leadership and collaboration. Among other important implications, the study recommended that, as a result of the positive and significant relationship established between the supported variables, stakeholders and management invest more into the training of hospital staffs in these critical areas of service delivery. Also, the study presented that, healthcare providers should be able to communicate with other professional in delivering healthcare.
Research on Artificial Intelligence Technology of Virtual Reality Teaching Method in Digital Media Art Creation
Authors: Juan Qian Juan Qian
Published: January 2022

The popularity of virtual reality technology has gradually expanded from the computer field to all aspects of life and has also become a new approach to digital media art. In this paper, we analyze the characteristics of virtual reality technology and the three commonly used methods and explore and practice them in-depth. The experimental results provide a concrete reference and comparison basis for the teaching and research fields. In this paper, 160 students from the same school were selected for the teaching experiment. They were divided into four groups and taught courses on different artificial intelligence-based methods of creating virtual reality digital media art for one semester. They were artificial intelligence-based image recognition technology, artificial intelligence-based speech recognition technology, artificial intelligence-based natural language processing technology and traditional teaching methods. At the end of the instruction, we obtained subjective and objective test scores for four students using the same tests. All scores indicated that the effectiveness was much higher than traditional methods, regardless of which virtual reality technology was used. In addition, we found that students were far more sensitive and enlightened to visuals and images than to language.

 
Recommendation Algorithm for Equilibrium of Teaching Resources in Physical Education Network Based on Trust Relationship
Authors: Xi Liang Xi Liang , Xi Liang Jiesen Yin
Published: January 2022

Aiming at the problems of poor balance of recommended resources in the recommendation of traditional physical education network teaching resources and low trust degree of recommended physical education network teaching resources, this paper proposes a balanced recommendation algorithm for physical education network teaching resources based on trust relationship. By SVM algorithm, the teaching resources of physical education network are classified, and then the invalid data of teaching resources of physical education network are deleted, and the remaining teaching resources of physical education network are taken as the extraction object to complete the extraction of teaching resources of physical education network. Through Kalman filtering method, the data of sports network teaching resources with noise are reduced, and then the data with high similarity are fused to complete the preprocessing of physical education network teaching resources data. By constructing the trust relationship model, the relationship attribute between the recommended physical education network teaching resources data is determined. The experimental results show that the highest degree of resource equilibrium recommended by the proposed method is about 96 and the recommended resource trust is high.
