Beluga whale stewardship and collaborative research practices among Indigenous peoples in the Arctic

Beluga whales ( Delphinapterus leucas ) are an integral part of many Arctic Indigenous cultures and contribute to food security for communities from Greenland, across northern Canada and Alaska to Chukotka, Russia. Although the harvesting and stewardship practices of Indigenous peoples vary among regions and have shifted and adapted over time, central principles of respect for beluga and sharing of the harvest have remained steadfast. In addition to intra-community cooperation to harvest, process and use beluga whales, rapid environmental change in the Arctic has underscored the need for inter-re-gional communication as well as collaboration with scientists and managers to sustain beluga populations and their cultural and nutritional roles in Arctic communities. Our paper, written by the overlapping categories of researchers, hunters, and managers, first provides an overview of beluga hunting and collaborative research in seven regions of the Arctic (Greenland; Nunatsiavut, Nunavik, Nunavut, and the Inuvialuit Settlement Region, Canada; Alaska; and Chukotka). Then we present a more detailed case study of collaboration, exam-ining a recent research and management project that utilizes co-production of knowledge to address the conservation of a depleted population of beluga in Nunavik, Canada. We conclude that sustaining traditional values, establishing collaborative management efforts, the equitable inclusion of Indigenous Knowledge, and respectful and meaningful collaborations among hunters, researchers and managers are essential to sustaining healthy beluga populations and the peoples who live with and depend upon them in a time of rapid social and environmental change.
Premade Nanoparticle Films for the Synthesis of Vertically Aligned Carbon Nanotubes

Carbon nanotubes (CNTs) offer unique properties that have the potential to address multiple issues in industry and material sciences. Although many synthesis methods have been developed, it remains difficult to control CNT characteristics. Here, with the goal of achieving such control, we report a bottom-up process for CNT synthesis in which monolayers of premade aluminum oxide (Al2O3) and iron oxide (Fe3O4) nanoparticles were anchored on a flat silicon oxide (SiO2) substrate. The nanoparticle dispersion and monolayer assembly of the oleic-acid-stabilized Al2O3 nanoparticles were achieved using 11-phosphonoundecanoic acid as a bifunctional linker, with the phosphonate group binding to the SiO2 substrate and the terminal carboxylate group binding to the nanoparticles. Subsequently, an Fe3O4 monolayer was formed over the Al2O3 layer using the same approach. The assembled Al2O3 and Fe3O4 nanoparticle monolayers acted as a catalyst support and catalyst, respectively, for the growth of vertically aligned CNTs. The CNTs were successfully synthesized using a conventional atmospheric pressure-chemical vapor deposition method with acetylene as the carbon precursor. Thus, these nanoparticle films provide a facile and inexpensive approach for producing homogenous CNTs.
Using Functional Outcomes to Predict Vestibular Loss in Children

Objective: The purpose of this study was to determine: (1) the relationship between vestibular loss severity and functional performance, (2) which functional performance outcomes best predict vestibular loss, and (3) which vestibular rate sensors (canals vs. otoliths) provide the most weighting during different functional measures. Study Design: Prospective. Setting: Tertiary referral center. Patients: Fifty-seven children with normal hearing (mean age: 12.3 years, 32 males) and 55 children with cochlear implants (mean age 12.8 years, 29 males). Intervention: Diagnostic. Main Outcome Measures: Video head impulse test, cervical vestibular evoked myogenic potential (cVEMP), ocular VEMP (oVEMP), single leg stance, Standing Balance Test, active and passive dynamic visual acuity, and the balance subtest of the Bruininks-Oseretsky Test of Motor Proficiency (BOT-2). Results: Performance worsened as vestibular loss severity worsened for all functional outcomes except the standing balance test conditions 1 and 2. The best outcomes for classifying children with vestibular loss were the single leg stance (cut-off criterion: 5 seconds; sensitivity and specificity of 88% and 86%) and the BOT-2 balance subtest (cut-off criterion of 27.5 points; sensitivity and specificity of 88% and 88%). Average horizontal canal vHIT gain was a significant predictor of all functional outcomes while neither corrected cVEMP amplitude nor oVEMP amplitude predicted performance. Conclusion: Functional performance declines as vestibular loss severity worsens. Single leg stance is fast and efficient for predicting vestibular loss in school age children. Average horizontal canal vHIT best predicts functional performance; if using a tiered approach, horizontal canal vHIT should be completed first.
Distortion In p-i-n Diode Control Circuits

Traditionally, distortion in p-i-n diodes has been thought to be only a function of the carrier lifetime and frequency of operation. This understanding is based on empirical evidence and is not entirely accurate. This paper will discuss the origins of p-i-n diode distortion and study the effects of various devices parameters on distortion performance. Included in the investigation on single-diode circuits will be switching circuits and reflective attenuators. In switch circuits, the analysis shows that distortion can be minimized by maximizing the stored-to-charge resistance ratio in the diode. In attenuators, the analysis shows that maximizing the i-region thickness will minimize distortion, independent of the device carrier life-time. In attenuators where multiple p-i-n diodes are used (the bridged-tee and PI are discussed), maximizing the i-region thickness also minimizes the distortion, independent of carrier lifetime. The model accurately predicts distortion signal cancellation in both single and multiple p-i-n diode circuits.
Effect of fire on concrete and concrete structures

The behaviour of concrete in fire depends on its mix proportions and constituents and is determined by complex physicochemical transformations during heating. Normal-strength concretes and high-performance concretes microstructurally follow similar trends when heated, but ultra-high-performance concrete behaves differently. A key property unique to concrete amongst structural materials is transient creep. Any structural analysis of heated concrete that ignores transient creep will yield erroneous results, particularly for columns exposed to fire. Failure of structural concrete in fire varies according to the nature of the fire; the loading system and the type of structure. Failure could occur from loss of bending or tensile strength; loss of bond strength; loss of shear or torsional strength; loss of compressive strength; and spalling of the concrete. The structural element should, therefore, be designed to fulfil its separating and/or load-bearing function without failure for the required period of time in a given fire scenario. Design for fire resistance aims to ensure overall dimensions of the section of an element sufficient to keep the heat transfer through this element within acceptable limits, and an average concrete cover to the reinforcement sufficient to keep the temperature of the reinforcement below critical values long enough for the required fire resistance period to be attained. The prediction of spalling – hitherto an imprecise empirical exercise – is now becoming possible with the development of thermohydromechanical nonlinear finite element models capable of predicting pore pressures. The risk of explosive spalling in fire increases with decrease in concrete permeability and could be eliminated by the appropriate inclusion of polypropylene fibres in the mix and/or by protecting the exposed concrete surface with a thermal barrier. There are three methods of assessment of fire resistance: (a) fire testing; (b) prescriptive methods, which are rigid; and (c) performance-based methods, which are flexible. Performance-based methods can be classified into three categories of increasing sophistication and complexity: (a) simplified calculations based on limit state analysis; (b) thermomechanical finite element analysis; and (c) comprehensive thermohydromechanical finite element analysis. It is only now that performance-based methods are being accepted in an increasing number of countries.
Speed-energy optimization of electrostatic actuators based on pull-in

The speed and total energy required to accomplish pull-in switching of a generic electrostatic actuator is examined. It is found that the value of the source resistance of the voltage drive used for switching has a profound effect on both switching speed and energy requirements. The source resistance governs the charging time for the actuating capacitor. As long as this time is slower than the time required to accelerate the moving mass to maximum speed in the presence of damping, the total energy required for switching can be dramatically reduced without a significant increase in switching time. Indeed, there exists a clear optimum source-resistance value that minimizes the product of switching time and switching energy. These findings are demonstrated theoretically and then applied to specific examples from the literature. In addition, the limiting case of very large source resistance, essentially a current drive, is evaluated and compared to the voltage-driven case. It is found that for equivalent switching times, the current drive requires less total energy for a switching event.
Visualizing and Analyzing Activities in an Integrated Space-Time Environment

An integrated space-time environment is demanded by activity-based travel studies to facilitate the investigation of spatial and temporal characteristics of activities. The current geographic information system (GIS), which has been successful in supporting trip-based travel analysis, does not include an explicit time representation and therefore is incapable of supporting activity-based travel analysis efficiently. This study proposes a temporal GIS design that incorporates the space-time path concept of Hägerstrand's time geography to facilitate the analysis of activities in a space-time context. The space-time path concept provides an efficient approach to organizing activities and travels in their space-time contexts and to supporting the investigation of spatiotemporal relationships between individuals. This study adopts the three-dimensional orthogonal space-time system in the temporal GIS design and develops representation and analysis functions related to space-time paths and individual activities. The proposed design is successfully implemented in a prototype system. The system provides an integrated space-time environment to effectively visualize activities and travels in their space-time contexts and analyze their spatiotemporal characteristics. Such a system offers useful tools to facilitate activity-based travel studies.
LSD1: Expanding Functions in Stem Cells and Differentiation

Embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSC) provide a powerful model system to uncover fundamental mechanisms that control cellular identity during mammalian development. Histone methylation governs gene expression programs that play a key role in the regulation of the balance between self-renewal and differentiation of ESCs. Lysine-specific demethylase 1 (LSD1, also known as KDM1A), the first identified histone lysine demethylase, demethylates H3K4me1/2 and H3K9me1/2 at target loci in a context-dependent manner. Moreover, it has also been shown to demethylate non-histone substrates playing a central role in the regulation of numerous cellular processes. In this review, we summarize current knowledge about LSD1 and the molecular mechanism by which LSD1 influences the stem cells state, including the regulatory circuitry underlying self-renewal and pluripotency.
ANFIS-Based Indoor Location Awareness System for the Position Monitoring of Patients

In this paper, an adaptive network based fuzzy inference system (ANFIS) combining a location awareness system (LAS) is used to to develop an application of patient's position monitoring system. The setup procedure of LAS is carried out in advanced, then the ANFIS is designed to demonstrate the performance of the proposed methodology. From experimental and simulation results, satisfactory performance of LAS for patient's position monitoring can be achieved.
Infected Facial Tissue Fillers Caused by Dental Infection

Injectable dermal fillers are widely used for facial rejuvenation; they help reshape the facial contours by treating volume loss due to aging changes. Facial fillers may become infected following a dental infection. In this report, we present a case of a 44-year-old female patient who presented with a swelling in her upper right buccal region following dental treatment of her second maxillary right premolar. After a thorough history, clinical, and radiological examinations, the diagnosis of infected dermal filler was made. The lesion was treated by association of two antibiotics (ciprofloxacin IM and clindamycin tablets 300 mg), and a complete healing was observed two months after the end of the dental treatments.
Behavior Coordination Methods on Autonomous Navigation of Physical Robot

Behavior based architecture gives robot fast and reliable action. If there are many behaviors in robot, behavior coordination is needed. Subsumption architecture and motor schema is example of behavior coordination methods. In order to study those methods characteristics, computer simulation is not enough, experiments in physical robot are needed to be done. It can be concluded from experiment result that the first method gives quick, robust but non smooth response. Meanwhile the latter gives smooth but slower response, and it is tend to reach target faster than the first one. Some limitation of physical robot experiment also presented here.
The Combinatorial Expressions and Probability of Random Generation of Binary Palindromic Digit Combinations

The aim of this paper is to obtain three types of expressions for calculating the probability of implementing palindromic digit combinations on a finite equally possible combination of zeros and ones. When calculating the probability of implementation of palindromic digit combinations, the classical definition of probability is applied. The main results of the paper are formulated in the form of three theorems. Moreover, the consequences of these theorems and typical examples of calculating the probability of implementing palindromic digit combinations in a data string of binary code are considered. All formulated theorems and their consequences are accompanied by proofs. The obtained numerical results of the paper can be used in the analysis of numerical computer data written as a binary code string in BIN format files. It should also be noted that the combinatorial expressions described in the article for calculating the number of palindromic combinations of digits in the binary number system can be used in number theory and in various branches of computer science. The development of these results from the point of view of obtaining an expression for calculating the number of palindromic combinations of digits in the binary number system contained in two-dimensional data arrays is also of immediate theoretical and practical interest. However, these results are not presented in this work, but they can be considered in subsequent publications.
The Nature and Evaluation of the Sharpness of Photographic Images

The ability of a photographic material to produce pictures having good definition is commonly referred to as its sharpness, which is a subjective concept. The objective quantity 〈G 2 x 〉 Av . DS is shown to be a physical measurement which correlates with sharpness judgments. 〈G 2 x 〉 Av is the mean of the square of the density gradients, ×D/×x, across an abrupt boundary between a light and a dark area in the developed image and DS is the density difference between these areas. 〈G 2 x 〉 Av is evaluated only for those values greater than 0.005 in density per micron which represents the threshold gradient. It is shown that, contrary to the generally accepted belief, resolving power does not correlate well with sharpness judgments and in some cases is even misleading.
Unmanned Aircraft Guidance for Penetration of Pretornadic Storms

This paper investigates unmanned aircraft guidance for a severe storm penetrator to assess the feasibility of such a mission and to optimize ingress in terms of flight time and exposure to precipitation. Understanding guidance-layer behavior and deriving control strategies will provide tools for developing mission-level concepts of operation and making vehicle design tradeoffs. A backward propagating wave front algorithm based on ordered upwind methods is developed for guidance-layer planning of severe storm penetration. Target areas for investigation by the aircraft are identified within simulated storm wind, hail, and precipitation data. The simulated data are used to determine the feasibility of storm penetration to the points of interest, along with calculating airframe exposure to precipitation. Ingress planning is also considered for a dynamic wind field using a receding horizon control approach to adapt the flight path in response to environmental changes.
Table-based dynamic FET model assembled from small-signal models

A data-table-based large-signal metal-semiconductor field-effect transistor model is presented based on an ensemble of bias-dependent small-signal equivalent circuits. The model is capable of accurate simulation of small-signal S-parameters as well as large-signal performance over the data-acquisition bias range. In addition to the dc current sources, the model contains two quasi-static charge sources and a dynamic radio frequency (RF) current source, which depends on the temperature rise. By introducing the dynamic RF current source, the problem of path dependence, which occurs in modeling large-size devices and devices with dispersion, is resolved. All equivalent elements are obtained by cubic spline interpolation. Extrapolation of the model beyond the measurement range is taken into account. The model is extracted by an in-house software without involving optimization. The validity of the model is demonstrated by comparing the simulation of small-signal S-parameters over a wide bias range, as well as power, linearity, and waveform characteristics to the measured data.
Nutrients and Dietary Approaches in Patients with Type 2 Diabetes Mellitus and Cardiovascular Disease: A Narrative Review

Cardiovascular disease (CVD) is the most common cause of morbidity and mortality in developed countries. The prevalence of CVD is much higher in patients with type 2 diabetes mellitus (T2DM), who may benefit from lifestyle changes, which include adapted diets. In this review, we provide the role of different groups of nutrients in patients with T2DM and CVD, as well as dietary approaches that have been associated with better and worse outcomes in those patients. Many different diets and supplements have proved to be beneficial in T2DM and CVD, but further studies, guidelines, and dietary recommendations are particularly required for patients with both diseases.
CUSTOS DE TRANSAÇÃO NA CADEIA PRODUTIVA DO TOMATE DE MESA

A cultura do tomate distingue-se em dois segmentos, o tomate industrial e tomate de mesa ou in natura. A produção e comercialização deste último caracteriza-se por sua heterogeneidade, tanto em escala de produção, quanto na destinação ao mercado, logo, custos adicionais podem ocorrer além daqueles envolvidos no processo produtivo. Desta forma, o presente estudo buscou analisar as transações da cadeia produtiva do tomate de mesa com enfoque no elo produtor em Goianápolis-GO, Brasil. Na metodologia, utilizou-se como técnica de abordagem a pesquisa quali-quantitativa. Quanto aos objetivos, ela caracterizou-se como exploratória e descritiva, quanto aos meios, escolheu-se o estudo de caso. Foram entrevistados 33 produtores de tomate de mesa entre 10 de setembro e 08 de novembro de 2018. Os resultados demostraram que 69,7% comercializam sua produção via CEASA - GO e 30,3%, via intermediários. Destes, 27,3% consideraram como fator mais positivo neste mercado, a facilidade de acesso ao comprador e o mais negativo, o risco de calote com 51,5%. Além disso, para 51,5% dos entrevistados, o maior desafio para essa comercialização são as oscilações no preço de venda. Conclui-se que pela dinâmica dessa comercialização há consideráveis custos de transação e uma das formas de mitigar esses custos seria os produtores se organizarem por meio de ações coletivas como cooperativas, associações, etc.
The Clinical Features and Prognosis of NPM1/FLT3-ITD/DNMT3A Triple-mutated Acute Myeloid Leukaemia

Purpose: Previous studies have shown that patients with NPM1+/FLT3-ITD+ acute myeloid leukaemia (AML) have a poor prognosis, especially those with a high FLT3-ITD allelic ratio. However, no studies have confirmed a clear prognostic impact of DNMT3A on NPM1+/FLT3-ITD+ AML patients. Methods: Our study included a total of 165 patients with newly diagnosed non-acute promyelocytic leukaemia (non-APL) AML at The First Hospital of Lanzhou University between January 2018 and June 2021. Further bioinformatics analysis was performed using the Gene Expression Omnibus (GEO) database. Results: We retrospectively studied 165 patients newly diagnosed non-APL AML and identified 11 (6.7%) patients with NPM1/FLT3-ITD/DNMT3A triple mutations. The patients with triple-mutated AML had advanced age, higher white blood cell (WBC) counts, de novo AML, normal karyotypes, and poor survival, and all were in the M4/M5 French-American-British (FAB) category. Notably, half of the patients with triple-mutated AML had mature monocyte characteristics that were difficult to distinguish from chronic myelomonocytic leukaemia (CMML). We validated the prognosis of patients with triple-mutated AML by further bioinformatics analysis and found that the GNG4 gene, one of the hub genes, was related to triple-mutated AML patients' survival. Conclusion: Our data demonstrate that DNMT3A gene mutation has adverse prognostic significance in NPM1+FLT3-ITD+comutation AML patients.
Field application of waterworks automated meter reading systems and analysis of household water consumption

AbstractAfter the construction of waterworks automated meter reading (AMR) systems with a 15-mm diameter smart water meter developed in this study, both the feasibility of field application of waterworks AMR and the patterns of household water consumption were evaluated. Average reception rate was 94.1% due to the communication blackout, and one-to-one communication with RF UHF and Internet (i.e. TCP/IP) was found to be more stable in AMR systems than multiple-to-one communication with RF UHF, DCU, and Wibro. Household water consumption clearly showed seasonal periodicity due to weather factors. Based on the analysis of liters per capita day (LPCD) for 80 households, the LPCD values were found to decrease gradually as the number of residents increased due to the saving effects through common consumption (i.e. washing, cooking, cleaning, irrigation, etc.). Relative to LPCD values of 100 control households without AMR systems, the LPCD values of 80 pilot households with AMR systems were reduced by 5.3%. Con.
