Published: May 2022

Background:Abdominal masses always are mystery in clinical practice. Improvements have taken place in fine needle aspiration cytology with technical advances in imaging methods of ultrasound and CT.

Aims:To study the utility of guided FNAC in the diagnosis of abdominal lesions and categories the abdominal lesions. To study cytological features of abdominal lesions and correlate with histopathological features wherever possible.

Materials and
methods: The study included 82 abdominal lesions. History, clinical features, radiological investigations were obtained in each case. USG or CT guidance was used and the FNA procedure was done. Smears were stained with Giemsa and viewed under the microscope for diagnosis. Diagnostic yield was 95%. Extra material obtained was given for cell block.

Results: The age was from 14 years old to 82 years and majority of them were in the age group of 40 – 60 years. Male to female ratio is 1:1.1. Among 82 cases, 45 cases (54.87%) were malignant, followed by 17 cases (20.74%) benign, 14 cases (17.08%) inflammatory, 04 cases (4.87%) suspicious of malignancy and 02 cases (2.44%) unsatisfactory for evaluation. Majority of the cases are in liver and hepatocellular carcinoma was the most common malignant lesion. In 60 cases histopathological correlation was available and for these cases the diagnostic accuracy is 95%, sensitivity is 92.1%, specificity is 100% and p value is <0.001 which is highly significant.

Conclusion:Abdominal fine needle aspiration cytology is simple, cost effective, rapid and repeatable procedure which helps in categorizing the abdominal lesions.

Authors: Hanif S. , Bhat K. A. , Sudhakara G.
Published: May 2022

A bipartite graph G can be treated as a (1,1) bipartite graph in the sense that, no two vertices in the same part are at distance one from each other. A (2,2) bipartite graph is an extension of the above concept in which no two vertices in the same part are at distance two from each other. In this article, analogous to complete (1,1) bipartite graphs which have the maximum number of pairs of vertices having distance one between them, a complete (2,2) bipartite graph is defined as follows. A complete (2,2) bipartite graph is a graph which is (2,2) bipartite and has the maximum number of pairs of vertices (u,v) such that d(u,v)=2. Such graphs are characterized and their properties are studied. The expressions are derived for the determinant, the permanent and spectral properties of some classes of complete (2,2) bipartite graphs. A class of graphs among complete (2,2) bipartite graphs having golden ratio in their spectrum is obtained.

Authors: KENDİRLİOĞLU ŞİMŞEK Gökçe , CETİN Ahmet Kadri
Published: May 2022

In recent years, microalgae have become the focus of attention because they are used in different fields (biodiesel, protein extraction, etc.). One disadvantage of microalgae is that their production costs are pretty high. This paper aimed to reduce the cultivation costs of Chlorella vulgaris, which is an important species in terms of protein and lipid content. Molasses solutions at different concentrations were used as media for the cultivation of C. vulgaris. Molasses is a byproduct of the extraction of sucrose from sugar beets. A Jaworski’s medium was used as the control group. C. vulgaris was inoculated into molasses media (0.5 g/L, 1 g/L, 2 g/L, and 4 g/L). Growth and protein, and lipid content were calculated for ten days. C. vulgaris had the highest growth in 4 g/L molasses medium on day five. It had the highest protein content in 2 g/L molasses medium on day five. It had the highest lipid content in 4 g/L molasses medium on day seven. The molasses media promoted the growth and the protein and lipid content of C. vulgaris. The results show that molasses media help significantly reduce microalgae cultivation costs.
A Review on Artificial Neural Network Approach in Data Mining
Authors: Mithun Mhatre  , Ranjeet Pawar
Published: May 2022

Data mining has been used as a term describing explorative analysis of large data sets (frequently stored in data warehouses with the objective to identify hidden relationships among the variables in the set). Artificial neural network is one of many tools for data mining. This paper summarizes the state-of-the-art of the principles beyond using neural models in data mining. Artificial Neural Networks are suitable in data-rich environments and are typically used for extracting embedded knowledge in the form of rules, quantitative evaluation of these rules, clustering, self-organization, classification and regression, feature evaluation and dimensionality reduction. In this paper, we try to understand the basics of neural network modeling, some specific applications, and the process of implementing a neural network in data mining.

Objetivo: O presente estudo piloto investigou o comportamento de uso de máscaras para a prevenção da COVID-19, tendo como objetivo determinar a magnitude do uso de máscaras em espaços públicos. Métodos: Trata-se de um estudo quantitativo de caráter prospectivo, realizado na cidade de Maputo, Moçambique, em fevereiro de 2020, com recurso da técnica de observação sistemática, através do uso de uma plataforma eletrônica de recolha de dados construído no Google Forms©, visando obter dados como o local, o sexo, o uso ou não de máscaras, bem como a forma de uso desta. A amostragem apresentou-se como aleatória sistemática, contando com uma amostra de 1.020 indivíduos, obtida em dois terminais de transporte rodoviário e um mercado, caracterizados por grandes aglomerações. Os dados colhidos passaram por análises de estatística descritiva, ANOVA e Teste T para amostras independentes. Resultados: Verificou-se que 72,9% (744) dos indivíduos traziam máscara, entretanto, apenas 53% (541) usava-a de forma adequada, cobrindo a boca e o nariz. As mulheres apresentaram uma média mais elevada comparativamente aos homens (t=4.471; p=0.000). Conclusão: O uso de máscaras em espaços públicos, avaliado na cidade de Maputo, pode ser considerado baixo, o que pressupõe altos níveis de vulnerabilidade para novas vagas do COVID-19.
Effect of Continuous Wave Interference on GNSS Receivers
Authors:   Hanoi University of Science and Technology, Hanoi, Vietnam
Published: May 2022

The positioning performance of GNSS receivers is strongly influenced by radio interferences, especially continuous wave interference (CWI). Recent studies have modeled the effects of the interference and have shown that the effect of the interference is strongest where the frequency offset between CWI interference and the GNSS signal is a multiple of 1KHz. However, these studies have not yet modeled the effect of phase offset between CWI interference and signal which has a significant impact on the positioning performance. In this paper, we present the effect of CWI interference on positioning performance considering the role of both frequency and phase offset. In addition, theoretical and simulation results also show that CWI noise does not significantly affect the signal with some specific values of phase offset.
The Effectiveness of LDPC Decoding Algorithms in 5G Channel Modelling of MIMO-OFDM System under the Influence of Spatial Correlation
Authors:   Hanoi University of Science and Technology, Hanoi, Vietnam
Published: May 2022

This paper investigates the spatial cross-correlation properties of 5G channel modeling in non-line of sight (NLOS) of Urban Micro Cell (UMi), Rural Macro Cell (RMa) and Indoor Cell (InH) at 6 GHz frequency band as Third Generation Partnership Project (3GPP) specification. In our spatial correlation Multiple-input multiple-output (MIMO) channel, when increasing the distances of BS antenna elements, the correlation characteristics of the channel dramatically vary, which leads to altering the observed system behavior. By analyzing the 5G LDPC code and using different decoding algorithms and code rates, we evaluate the system’s performance by Bit Error Rate (BER) in a wideband correlated Multiple-input multiple-output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system. In our spatial correlation, the more rising of the distances of antenna elements on the BS side, the better the effectiveness of the LDPC decoding algorithms achieved. Of the Belief Propagation based (BP-based) Algorithm, Offset Minimum-Sum (OMS) Algorithm and Linear Approximation Minimum-Sum (LAMS) Algorithm, we propose to use the LAMS decoding algorithm with a high code rate of 5/6 in our spatial correlated wideband channel because of lower complexity and more efficiency in term of the system’s performance.

Makala hii inaonyesha tofauti iliyopo kati ya majukumu na maumbo ya uhusika katika vichwa vya habari vya siasa kwenye gazeti la Taifa Leo. Nadharia ya uhusika iliyoasisiwa na Charles Fillmore mnamo mwaka wa 1968 imeongoza uchunguzi huu. Utafiti huu umefanywa baada ya kubaini kuwa wasomi mbalimbali wa gazeti hutafsili maana anuwai kwenye kichwa kimoja cha habari za siasa. Jambo hili husababisha utata wa kimaana na uenezaji wa jumbe zisizoithibatika katika jamii, hivyo basi, kuzalisha migogoro ya kisiasa nchini. Upekuzi wa yaliyomo kwenye matoleo ya gazeti la Taifa Leo ambayo yametawaliwa na vichwa vya habari za siasa na kuchapishwa kati ya mwaka 2017-2019 ni msingi wa data ya utafiti huu. Vichwa kumi na vinane vya habari za siasa vilisampulishwa kimakusudi na kutumika katika uchambuzi wa uchunguzi huu. Data katika makala hii imewasilishwa kupitia mfumo wa majedwali na maelezo. Matokeo ya tathmini ya uchunguzi huu yameshikilia kwamba Kiswahili hakina maumbo dhahiri ya uhusika ispokuwa katika nomino ambazo nafasi yake yaweza kuchukuliwa na viwakilishi vya nafsi ya pili na tatu umoja na wingi. Katika vichwa vya habari ambavyo nomino zake si za ngeli ya A-WA, viwakilishi faafu vya nomino hizo huchukua nafasi hiyo na kuwa maumbo ya uhusika. Kila aina ya uhusika ina jukumu lake la uhusika. Majukumu ya uhusika ni dhahania na hubadilika kulingana na aina ya uhusika. Uchunguzi huu utakuwa wenye umuhimu kwa wasomi wa magazeti na taifa kijumla. Wasomi wa magazeti wataongozwa na kigezo cha dhima ya maneno katika tungo kudondoa maana sawa katika vichwa lengwa vya habari za kisiasa na kupitisha tafsili hiyo moja kwa wanajamii. Kwa kufanya hivi, migogoro ya kisiasa katika jamii iletwayo na tafsili mbalimbali za kimaana itafutiliwa mbali.

Status and distribution of Arroyo Chub within its native range
Authors: O’Brien John W , Barabe Russell M
Published: May 2022

The Arroyo Chub (Gila orcutti) is a small cyprinid native to coastal drainages of Los Angeles, Orange, Riverside, and San Diego counties. We surveyed the seven drainages historically known to support the species in 2012-2014 and again in 2019 to determine current range and distribution. We compared our results to the most recent species account we could locate (1993). We detected Arroyo Chub in 18 of the 40 streams (45%) and within six of the seven native watersheds in our 2012-2014 surveys, while our 2019 surveys located fish in all of the seven native watersheds. This native species has retreated to the headwaters in most watersheds and the number of populations have declined since the most recent species account. Non-native species, habitat loss, urbanization, water development, flood control, and drought are thought to be the primary causes of this decline.

Fritz Haber e as duas faces do ser e do saber
Authors: Moreno Esteban Lopez
Published: May 2022

A ascensão do conhecimento acadêmico fez surgir diversas contribuições benfazejas para a sociedade, ao mesmo tempo que trouxe à tona efeitos preocupantes, como a intensificação de atitudes psicológicas de indiferença e distanciamento do afeto humano e da solidariedade social. Tal ambivalência é aqui analisada através do exemplo de vida de um casal extraordinário de cientistas: o químico judeu alemão Fritz Haber (1868-1934), cujas descobertas resultaram na sobrevivência de milhões de pessoas; e a judia alemã Clara Immerwahr (1870-1915), uma cientista pioneira cujo renome demorou mais para ser reconhecido. Haber foi incapaz de tornar bom e sustentável seu relacionamento conjugal com Immerwahr, talvez por causa de sua apatia ou do uso antiético de suas descobertas na Química. Outros personagens são aqui contextualizados para concluir sobre a necessidade de conciliação entre a simplicidade perante a vida e o academicismo.

The article presents the results of a study of changes in the indicators of general, biochemical blood tests and individual coagulogram parameters in patients with COVID-19 pneumonia who were in hospital. The authors found that patients with COVID-19 pneumonia had leukopenia, accelerated ESR, thrombocytopenia, lymphopenia, neutrophilia, which were more often observed in patients with lesions of 25% or more of lung tissue. Leukocytosis was only in 3 (3.7%) patients and only in severe lung damage. An increase in the plasma level of D-dimer, fibrinogen, procalcitonin, lactate dehydrogenase, an increase in the value of the prothrombin index, a decrease in the level of plasma albumin was detected only with a lesion of 50% or more of lung tissue. There was also an increase in the plasma levels of creatinine, alanine aminotransferase, aspartate aminotransferase, creatine phosphokinase, and C-reactive protein in the examined patients. The possibility of risk stratification and assessment of the need for hospitalization of patients with COVID-19 pneumonia, determination of the severity of the course of viral interstitial SARS-CoV-2 pneumonia, evaluation of the effectiveness of prescribed therapy and its correction using laboratory predictors is relevant, among other things, to reduce the risk of post-infectious complications, prevention of possible death.
INFLUENCE OF BREASTFEEDING ON ANTHROPOMETRIC INDICATORS AND HORMONAL STATUS OF LARGE AND SMALL FOR GESTATIONAL AGE CHILDREN IN THE DYNAMICS OF THE FIRST TWO YEARS OF LIFE
Authors:   Belarusian State Medical University, V.A. Prylutskaya , A.V. Sukalo ,   Belarusian State Medical University
Published: May 2022

The most important regulators of the rate of growth and physical development in children are rational nutrition and hormones. The aim is to evaluate the effect of breastfeeding on the anthropometric parameters and hormonal profile of large and small for gestational age children in the dynamics of the first two years of life. 280 full-term newborns were examined with dynamic follow-up during 2 years of life. The main group 1 (Gr1) ‒ 110 large for gestational age, Gr2 ‒ 95 small for gestational age, the control group ‒ 72 with indicators corresponding to the gestational age. The dynamics of anthropometric indicators, the nature of feeding, nutritional and hormonal status were analyzed, taking into account body weight at birth. It has been established that infants with low birth weight during the first year of life are significantly less likely to receive exclusively breast milk. The proportion of children who received exclusive breastfeeding in the neonatal period is lower than in the control group (p=0.002). Correlations between the duration of breastfeeding and indicators of physical development and adipokines status in newborns and young children have been established. Three-month-old low birth weight infants treated with breast milk substitutes showed a higher level of IGF-1 (p=0.047) and a lower concentration of adiponectin (p=0.045) in blood serum. In large for gestational age infants, a higher content of IGF-1 (p=0.029) and insulin (p=0.015) was established. The revealed features of anthropometric and hormonal status substantiate the importance of providing conditions for long-term breastfeeding, continuity in the provision of medical care to small and large for gestational age babies, and educational work with parents.

Published: May 2022

In modern clinical otorhinolaryngology, there are different opinions regarding the choice of the surgical approach for interventions on the paranasal sinuses. There are two main options for access to the paranasal sinuses - these are extra- and endonasal approaches, each of which has advantages and disadvantages. In some cases, when using open access, a bone defect of the anterior sinus wall occurs, leading to the development of various pathological conditions. Analyzing the possible outcomes of postoperative changes in the sinuses, many researchers are unanimous in the opinion that the presence of postoperative defects in the walls of the sinuses larger than 1 cm lead to the development of scar changes in the mucous membrane, deformation of the sinus, the development of postoperative neuralgia of the second branch of the trigeminal nerve associated with compression of the nervous ending with a postoperative scar. Variants of using various materials for plastics of postoperative bone defects of the paranasal sinuses are considered, the main advantages and disadvantages of using materials based on autobone, allogeneic bone and cartilage grafts, and various materials of non-biological origin are analyzed. Clinical experience of using allogeneic materials for plastics of facial bone defects is presented.

Gonarthrosis is a chronic progressive degenerative-dystrophic disease of the knee joint, characterized by destruction of the articular cartilage, changes in the articular surfaces of the epiphyses of the bones and periarticular soft tissues. Total knee arthroplasty (TKA) is an effective and often the only way to restore lost limb function when conservative treatment or joint-preserving surgery fails. TKA is a reconstructive surgical intervention that consists in replacing pathologically altered articular surfaces of the femur and tibia (in some cases, the patella) with artificial ones to eliminate or reduce the intensity of the pain syndrome, restore mobility in the knee joint and support ability of the lower limb. Dissatisfaction with the quality of postoperative pain relief (TKA) requires the search for new schemes and methods of treatment. In recent years, the use of local infiltration anesthesia and peripheral nerve blocks has become increasingly popular. The object of the study is 138 patients (114 women and 24 men) with knee arthroplasty who were treated at the 6th City Clinical Hospital of Minsk from 2019 to 2020.

Published: May 2022

Juvenile idiopathic arthritis (JIA) is one of the most common and most disabling rheumatic diseases in children. Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with unknown etiology, which is based on a genetically determined dysregulation of immunity. In recent years, the view of JIA and SLE as potentially incurable and prognostically unfavorable diseases has been revised. This is largely due to the expansion of the possibilities of early diagnosis of JIA, SLE, which allows starting active therapy at the onset of the disease, the development of a new class of basic anti-inflammatory drugs, and scientific research in the genetics of both diseases. A large number of genes associated with immune responses can, induce an autoimmune response - the leading pathogenetic link in both diseases. The article presents modern data on the possible pathogenesis, spectrum of clinical manifestations of juvenile idiopathic arthritis (JIA) and systemic lupus erythematosus (SLE) in children. A brief description of the pathological changes in JIA and SLE is given. Possible factors are considered, incl. genetic, affecting the predisposition to the disease, the process of the formation of organ damage. The issues of assessing the activity of diseases, assessing the quality of life of patients are discussed in detail.

Auditory Neuropathy Spectrum Disorders, ANSD is a state of the auditory system in which the patient has otoacoustic emissions (OAEs) and/or cochlear microphonic potential (CMP), and auditory brainstem responses (ABRs) are absent or significantly reduced. In contrast to sensorineural hearing loss, where the outer and inner hair cells of the cochlea are damaged, in ANSD the outer hair cells are preserved. The complexity of ANSD detection and the variety of clinical symptoms of this disorder make it difficult to differentiate this disease from sensorineural hearing loss. Purpose. Improvement of the differential diagnosis of ANSD and sensorineural hearing loss by defining the main anamnestic and audiological criteria. Materials and methods. The research included 2 groups of patients: the core group - 48 patients with bilateral ANSD and the control group - 30 patients with bilateral chronic sensorineural hearing loss. All patients underwent assessment of the anamnesis data, impedance measurement, tone threshold audiometry, registration of OAE (TEOAE), registration of ABR with allocation of CMP, registration of stationary auditory evoked potentials. Results. In patients with ANSD the incidence of prematurity, low birth weight, and hyperbilirubinemia is significantly higher (p <0.05) than in patients with sensorineural hearing loss. In patients with ANSD the 35delG mutation in the GJB2 gene was not identified, in contrast to patients with sensorineural hearing loss (genetic factor was confirmed in 23.3%) (p <0.05). Newborn hearing screening on both sides was conducted in 15 children (31.3%) with ANSD and only 1 child (3.3%) with sensorineural hearing loss (p <0.05). In 8 patients (16.7%) with ANSD was recorded TEOAE during the initial audiological diagnosis, in contrast to sensorineural hearing loss (TEOAE was not recorded in 100% of patients) (p <0.05). In contrast to sensorineural hearing loss, the ABR thresholds in ANSD did not correspond to the behavioral hearing thresholds. CMP was recorded on the right and left ear in all patients (100%) with ANSD and remained unchanged during the observation process, in contrast to patients with sensorineural hearing loss, in whom CMP was not recorded on both sides (p <0.05). Conclusions. The structure of the main risk factors for hearing loss in children with ANSD and sensorineural hearing loss is different. In the differential diagnosis with sensorineural hearing loss, the possibility of TEOAE disappearance in ANSD should be taken into account. Registration of ABRs with the allocation of CMP is the most informative method of ANSD diagnostics. CMP registration should be conducted for all patients who do not have ABR peaks at the maximum stimulus intensity, regardless of the OAE registration results.

Published: May 2022

Modern medicine faces the problem of the steady growth of alcoholic pathology. And as you know, morbidity and mortality with regular consumption of alcoholic beverages is associated with the toxic effects of ethanol on the most important human organs and, first of all, the liver. To date, a sufficient number of facts have accumulated indicating the importance of liver arginase in vital processes in health and disease. The aim of the study was to elucidate the significance of liver arginase in the detoxification processes and the development of oxidative stress in rats with chronic ethanol intoxication of different severity. In experiments on rats using modern physiological, biochemical research methods and a pharmacological approach, it was found that liver arginase participate in changes in liver detoxification function and the development of oxidative stress induced by chronic ethanol intoxication. The direction and severity of changes in arginase activity and liver detoxification function during chronic alcoholism depends on the severity of chronic alcohol intoxication. Under the influence of daily intragastric administration for 60 days, a 30% aqueous solution of ethanol (3.5 g 92% ethanol per kg of body weight) in animals under conditions of development of oxidative stress inhibited the activity of arginase and detoxification function of the liver, and the introduction of 10% aqueous solution of ethanol (1.0 g 92% ethanol per kg of body weight) for 2 months leads to an increase in the activity of liver arginase and detoxification processes. The action in the body of the arginase inhibitor Nω-hydroxy-nor-L-arginine contributes to the development of characteristic changes in the processes of detoxification and lipid peroxidation in the liver during chronic alcohol intoxication caused by intragastric the introduction of ethanol at a dose of 3.5 g / kg for 60 days.
Contrôle des microparticules avec des cristaux liquides
Authors: PENG Chenhui , D. LAVRENTOVICH Oleg
Published: May 2022

Ce chapitre traite de l’action d’un milieu cristal liquide sur la dynamique des particules vivantes ou inertes. Ainsi, l’ordre orientationnel des cristaux liquides rend l’électrophorèse et électro-osmose non linéaires. De même, les mésophases lyotropes aqueuses agissent sur la dynamique des micronageurs tels que les bactéries flagellées. La distribution spatiale, la polarité des trajectoires et les modes collectifs sont fonction de l’ordre orientationnel.
D’une lecture hégélienne à une lecture smithienne de Rawls
Authors: EGE Ragip , IGERSHEIM Herrade
Published: May 2022

L’analyse de l’œuvre de Rawls, dont l’évolution est remarquable de Théorie de la justice à Libéralisme politique, nous conduit à mettre en avant deux éléments fondamentaux : la question de la réconciliation du raisonnable et du rationnel, d’une part ; la problématique de l’évolution des préférences individuelles dès lors que les membres de la société sont confrontés à autrui, d’autre part. Dans ce chapitre, nous montrons en quoi Hegel et Smith permettent de mieux comprendre la théorie rawlsienne quant à ces deux aspects.
Gestion publique de l’eau et territoire : l’épreuve délibérative
Authors: RIEGEL Julie
Published: May 2022

En France, les politiques de l’eau sont subsidiaires et décentralisées, ce qui favorise la mise en dialogue des projets de gestion des bassins versants, qui suscitent pourtant une conflictualité locale persistante. Celle-ci peut s’alimenter d’une incompréhension des acteurs publics à l’égard des aspirations des riverains. Pour ces derniers, la légitimité d’un projet de territoire ne relève pas forcément de sa pertinence technique, mais de sa dimension de justice sociale, dans ses composantes de distribution, de reconnaissance et de participation.

Abstract. Accurate estimates of carbon–climate feedbacks require an
independent means for evaluating surface flux models at regional scales. The
altitude-integrated enhancement (AIE) derived from the Arctic Carbon
Atmospheric Profiles (Arctic-CAP) project demonstrates the utility of this
bulk quantity for surface flux model evaluation. This bulk quantity
leverages background mole fraction values from the middle free troposphere,
is agnostic to uncertainties in boundary layer height, and can be derived
from model estimates of mole fractions and vertical gradients. To
demonstrate the utility of the bulk quantity, six airborne profiling surveys
of atmospheric carbon dioxide (CO2), methane (CH4), and carbon
monoxide (CO) throughout Alaska and northwestern Canada between April and
November 2017 were completed as part of NASA's Arctic–Boreal Vulnerability
Experiment (ABoVE). The Arctic-CAP sampling strategy involved acquiring
vertical profiles of CO2, CH4, and CO from the surface to 5 km
altitude at 25 sites around the ABoVE domain on a 4- to 6-week time
interval. All Arctic-CAP measurements were compared to a global simulation
using the Goddard Earth Observing System (GEOS) modeling system. Comparisons
of the AIE bulk quantity from aircraft observations and GEOS simulations of
atmospheric CO2, CH4, and CO highlight the fidelity of the modeled
surface fluxes. The model–data comparison over the ABoVE domain reveals that
while current state-of-the-art models and flux estimates are able to capture
broad-scale spatial and temporal patterns in near-surface CO2 and
CH4 concentrations, more work is needed to resolve fine-scale flux
features that are captured in CO observations.

Abstract. Several studies have investigated new particle formation (NPF) events from
various sites ranging from pristine locations, including forest sites, to
urban areas. However, there is still a dearth of studies investigating NPF
processes and subsequent aerosol growth in coastal yet semi-urban sites,
where the tropospheric layer is a concoction of biogenic and anthropogenic
gases and particles. The investigation of factors leading to NPF becomes
extremely complex due to the highly dynamic meteorological conditions at the coastline especially when combined with both continental and oceanic weather conditions. Herein, we engage in a comprehensive study of particle number size distributions and aerosol-forming precursor vapors at the coastal semi-urban site in Helsinki, Finland. The measurement period, 25 June–18 August 2019, was timed with the recurring cyanobacterial summer bloom in the Baltic Sea region and coastal regions of Finland. Our study recorded several regional/local NPF and aerosol burst events during this period. Although the overall anthropogenic influence on sulfuric acid (SA) concentrations was low during the measurement period, we observed that the regional or local NPF events, characterized by SA concentrations on the order of 107 molec.cm-3, occurred mostly when the air mass traveled over the land areas. Interestingly, when the air mass traveled over the Baltic Sea, an area enriched with algae and cyanobacterial blooms, high iodic acid (IA) concentration coincided with an aerosol burst or a spike event at the measurement site. Further, SA-rich bursts were seen when the air mass traveled over the Gulf of Bothnia, enriched with cyanobacterial blooms. The two most important factors affecting aerosol precursor vapor concentrations, and thus the aerosol formation, were speculated to be (1) the type of phytoplankton species and intensity of bloom present in the coastal regions of Finland and the Baltic Sea and (2) the wind direction. During the events, most of the growth of sub-3 nm particles was probably due to SA, rather than IA or methane sulfonic acid (MSA); however much of the particle growth remained unexplained indicative of the strong role of organics in the growth of particles, especially in the 3–7 nm particle size range. Further studies are needed to explore the role of organics in NPF events and the potential influence of cyanobacterial blooms in coastal locations.

Abstract. Water diversion systems play crucial roles in assuaging flood risk by diverting and redistributing water within and among basins. For flood and drought assessments, including investigations of the effects
of diversion systems on river discharge worldwide, the explicit inclusion of these systems into global hydrological models (GHMs) is essential. However, such representation remains in the pioneering stage because of complex canal operations and insufficient data. Therefore, we developed a regionalized
canal operation scheme and implemented it in the H08 GHM for flood diversion in the Chao Phraya River basin (CPRB), Thailand, which is a complex river network with several natural and artificial diversion canals and has been
subject to severe flooding in the past, including recent years. Region-specific validation results revealed that the enhanced H08 model with the regionalized diversion scheme could effectively simulate the observed flood diversion pattern in the CPRB. Diverted water comprises approximately 49 % of the annual average river discharge in the CPRB. The simulations
further confirmed that the presented canal scheme had the potential to reduce flood risk in the basin by significantly reducing the number of flooding days. A generalized canal scheme with simple input data settings was also constructed for future global applications, providing insights into the maximum level of discharge reduction achievable with diversion of nearly 57 % of the annual average river discharge of the CPRB. Overall, the enhanced H08 model with canal schemes can be adapted and applied to different contexts and regions, accounting for the characteristics of each river network by maintaining the basic principles unaltered.
VEHICLE INSTANCE SEGMENTATION WITH ROTATED BOUNDING BOXES IN UAV IMAGES USING CNN
Authors: El Amrani Abouelassad S. , Rottensteiner F.
Published: May 2022

Abstract. Vehicle instance segmentation is a major but challenging task in aerial remote sensing applications. More importantly, the current majority methods use horizontal bounding boxes which does not tell much about the orientation of vehicles and often leads to inaccurate mask proposals due to high background to foreground pixel-ratio. Given that the orientation of vehicles is important for numerous applications like vehicle tracking, we introduce in this paper a deep neural network to detect and segment vehicles using rotated bounding boxes in aerial images. Our method demonstrates that rotated instance segmentation improves the mask predictions, especially when objects are not axis aligned or are touching. We evaluate our model on the ISPRS benchmark dataset and our newly introduced UAV dataset for vehicle segmentation and show that we can significantly improve the mask accuracy compared to instance segmentation using axis-aligned bounding boxes.

Published: May 2022

Abstract. Data are a key component for many applications and methods in the domain of photogrammetry and remote sensing. Especially data-driven approaches such as deep learning rely heavily on available annotated data. The amount of data is increasing significantly every day. However, reference data is not increasing at the same rate and finding relevant data for a specific domain is still difficult. Thus, it is necessary to make existing reference data more accessible to the scientific community as far as possible in order to make optimal use of it. In this paper we provide an overview of the development of our photogrammetry and remote sensing specific Benchmark Metadata Database (BeMeDa). BeMeDa is based on MongoDB, a NoSQL database system. In addition, the development of a user-oriented metadata schema serves for data structuring. BeMeDa enables easy searching of benchmark datasets in the field of photogrammetry and remote sensing.
IMPROVED RRS AND TURBIDITY RETRIEVAL FROM OLI IMAGES IN COMPLEX INLAND WATERS: A CASE STUDY FOR LAGUNA DE BAY
Authors: Felix M. J. , Perez G. J.
Published: May 2022

Abstract. Spatiotemporal monitoring of water quality parameters such as turbidity in inland waters is desirable to better understand productivity and mitigate the negative impacts of pollution induced by increasing anthropogenic activities. However, precise retrieval of water quality parameters in complex turbid waters from the remote sensing reflectance Rrs, remains a challenging task due to the varying optical complexity of the water body. In this study, a modified version of the Atmospheric Correction for OLI-lite (ModACO) scheme for turbid inland waters, which implements a linear extrapolation of NIR aerosol reflectance in the visible bands instead of a nonlinear function, is presented. The performance of the proposed method and other existing algorithms such as the Atmospheric Correction for OLI-lite (ACOLITE), Management Unit of the Noth Seas Mathematical Models (MUMM) scheme, SeaDAS standard processing, and SWIRE were evaluated. The Rrs retrievals from these models were then used as input for turbidity estimation and mapping of Laguna de Bay. Results show lowest Rrs error in all five spectral bands (443, 482, 561, 655, and 865 nm) on ModACO-based retrievals. Relative to the ACOLITE and other atmospheric correction schemes, the proposed method reduced the Rrs retrieval errors in terms of RMSE and MAPE by more than 50%. Similarly, significant improvements in turbidity retrievals were achieved from ModACO-based Rrs values, wherein comparable accuracy was observed from red/green ratio and the single NIR band turbidity models. Turbidity maps of Laguna de Bay show elevated values from the mid of dry season, which may be associated with point source discharge and wind-induced resuspension of bottom sediments. The lake turbidity then drops by the end of dry season, which is linked to the absence of prevailing strong winds that may increase in-water mixing. Using the aforementioned method, accurate monitoring of turbidity can be done to determine and mitigate possible degradation on the water quality of Laguna de Bay and other productive turbid inland waters.
