A Machine Learning–based Direction-of-origin Filter for the Identification of Radio Frequency Interference in the Search for Technosignatures
Authors: Pinchuk Pavlo , Margot Jean-Luc
Published: January 2022

Radio frequency interference (RFI) mitigation remains a major challenge in the search for radio technosignatures. Typical mitigation strategies include a direction-of-origin (DoO) filter, where a signal is classified as RFI if it is detected in multiple directions on the sky. These classifications generally rely on estimates of signal properties, such as frequency and frequency drift rate. Convolutional neural networks (CNNs) offer a promising complement to existing filters because they can be trained to analyze dynamic spectra directly, instead of relying on inferred signal properties. In this work, we compiled several data sets consisting of labeled pairs of images of dynamic spectra, and we designed and trained a CNN that can determine whether or not a signal detected in one scan is also present in another scan. This CNN-based DoO filter outperforms both a baseline 2D correlation model and existing DoO filters over a range of metrics, with precision and recall values of 99.15% and 97.81%, respectively. We found that the CNN reduces the number of signals requiring visual inspection after the application of traditional DoO filters by a factor of 6–16 in nominal situations.

We present results of a search for periodic gravitational wave signals with frequencies between 20 and 400 Hz from the neutron star in the supernova remnant G347.3-0.5 using LIGO O2 public data. The search is deployed on the volunteer computing project Einstein@Home, with thousands of participants donating compute cycles to make this endeavour possible. We find no significant signal candidate and set the most constraining upper limits to date on the amplitude of gravitational wave signals from the target, corresponding to deformations below 10−6 in a large part of the band. At the frequency of best strain sensitivity, near 166 Hz, we set 90% confidence upper limits on the gravitational wave intrinsic amplitude of

Published: January 2022

A spectral survey of methyl acetylene (CH3CCH) was conducted toward the hot molecular core/outflow G331.512-0.103. Our APEX observations allowed the detection of 41 uncontaminated rotational lines of CH3CCH in the frequency range between 172 and 356 GHz. Through an analysis under the local thermodynamic equilibrium assumption, by means of rotational diagrams, we determined T
exc = 50 ± 1 K, N(CH3CCH) = (7.5 ± 0.4) × 1015 cm2, X[CH3CCH/H2] ≈ (0.8–2.8) × 10−8, and X[CH3CCH/CH3OH] ≈ 0.42 ± 0.05 for an extended emitting region (∼10″). The relative intensities of the K = 2 and K = 3 lines within a given K-ladder are strongly negatively correlated to the transitions’ upper J quantum number (r = −0.84). Pure rotational spectra of CH3CCH were simulated at different temperatures, in order to interpret this observation. The results indicate that the emission is characterized by a nonnegligible temperature gradient with upper and lower limits of ∼45 and ∼60 K, respectively. Moreover, the line widths and peak velocities show an overall strong correlation with their rest frequencies, suggesting that the warmer gas is also associated with stronger turbulence effects. The K = 0 transitions present a slightly different kinematic signature than the remaining lines, indicating that they might be tracing a different gas component. We speculate that this component is characterized by lower temperatures and therefore larger sizes. Moreover, we predict and discuss the temporal evolution of the CH3CCH abundance using a two-stage zero-dimensional model of the source constructed with the three-phase Nautilus gas-grain code.

Published: January 2022

This paper provides current data on the biodiversity of boreal lakes of the Vologda Region (north-western Russia), including macrophytes (vascular plants and macroscopic algae) and macrophyte inhabitants (invertebrates and microalgae). The raw data, given in two datasets (Sampling event dataset and an Occurrence dataset) and presented in the form of GBIF-mediated data, were collected from 139 lakes (macrophytes between 2005 and 2021, macrophyte inhabitants between 2014 and 2020). The dataset contains materials on the diversity of vascular plants (Tracheophyta, 3225 occurrences; Bryophyta, 155; Marchantiophyta, 16), macro- and microalgae (Ochrophyta, 546 occurrences; Chlorophyta, 193; Charophyta, 153; Cyanobacteria, 139; Cryptophyta, 86; Myzozoa, 33; Euglenozoa, 27; Rhodophyta, 8; Bigyra, 1) and aquatic invertebrates (Arthropoda, 1408 occurrences; Annelida, 487; Mollusca, 263; Platyhelminthes, 36; Cnidaria, 11). This paper summarises previously unpublished materials in a standardised form.

The paper summarises the data collected during the long-term phytodiversity studies in a series of lakes of different types (Vologda Region, north-western Russia). Data on algae and invertebrates diversity were obtained in 60 different plant communities of aquatic, semi-aquatic and coastal plants or their combinations. A total of 6787 occurrences were included in the dataset, published in the global biodiversity database (GBIF) for the first time. According to the GBIF taxonomic backbone, the dataset comprised 837 taxa, including 711 lower-rank taxa (species, subspecies, varieties, forms). New records of 47 species rare and protected in the Vologda Region are given: 43 species of plants, three species of animals and one species of Cyanobacteria.
Rank‐optimal assignments in uniform markets
Authors: Nikzad Afshin
Published: January 2022

We prove that in a market where agents rank objects independently and uniformly at random, there exists an assignment of objects to agents with a constant average rank (i.e., an average rank independent of the market size). The proof builds on techniques from random graph theory and the FKG inequality (Fortuin et al. (1971)). When the agents' rankings are their private information, no Dominant Strategy Incentive Compatible mechanism can implement the assignment with the smallest average rank; however, we show that there exists a Bayesian Incentive Compatible mechanism that does so. Together with the fact that the average rank under the Random Serial Dictatorship (RSD) mechanism grows infinitely large with the market size, our findings indicate that the average rank under RSD can take a heavy toll compared to the first‐best, and highlight the possibility of using other assignment methods in scenarios where average rank is a relevant objective.
The extrinsic factors affecting patient access, referral and treatment of lung cancer in selected oncology public health facilities in KwaZulu-Natal

Published: January 2022

Patients’ insights into the factors affecting access, referral and treatment of lung cancer in public healthcare facilities, are key to the fight against this disease. On the other hand, the lack of epidemiological information on the actual burden of lung cancer, makes it difficult for public healthcare facilities to be adequately equipped to deal with foreseeable challenges in the oncology units. In order to inform patientcentred interventions and lung cancer control programmes, this study explored extrinsic factors that affect lung cancer patients throughout the cancer care continuum in KwaZulu-Natal. Nineteen patients receiving care in the three public healthcare facilities providing oncology services in KwaZulu-Natal, were interviewed using an interview guide. Following data saturation, thematic analysis was used to develop the themes relating to the extrinsic factors affecting the provision of cancer care. Five themes emerged from the analysis, namely: geographical dynamics affecting patient access to a healthcare facility, lung cancer suspicion index in the diagnostic trail within the different levels of care, decision-making trail for the referral system, equipmentinduced delays and healthcare-patient communication. A number of lung cancer patients utilising oncology services in public healthcare facilities in KwaZulu-Natal, are often met with various extrinsic factors affecting their progression through different stages of cancer care continuum. Therefore, the results of the extrinsic factors explored in this paper through the lung cancer patients’ lenses may be used for designing mitigation plans to reduce delays in lung cancer care in KwaZulu-Natal.

O ZNAČENjU VEZNIKA „KAD(A)“ U ZAVISNOSLOŽENOJ VREMENSKOJ REČENICI
Authors:   University of Belgrade, Faculty of Philology, Stanojević Veran J.
Published: January 2022

Based on certain principles of the processing of temporal information in the framework of dynamic semantics such as Discourse Representation Theory (Kamp, Reyle 1993), in this paper, we examine the semantic role of the conjunction kad(a) (when) which introduces tem- poral clauses in Serbian. Starting from the supposed function of the temporal clause at the discourse level, we claim that the role of the conjunction kad(a) reflects its discourse function in which, together with the predicate of the subordinate clause, it contributes to updating the current reference point. Although this discourse function in dynamic semantic frameworks only characterizes events, we argue that, under certain conditions, it can also be attributed to the conjunction kad(a) when it occurs with atelic predicates in the subordinate clause. The temporal relations between the actions of the main and those of the subordinate clause essen- tially depend on the type of the main predicate. Only event predicates can update the current reference point, which produces the effect of temporal succession between the predicates in the sentence. On the other hand, with atelic predicates one expressеs simultaneity, with the possible exception of immediate posteriority, which could be explained away by pragmatic factors. After all, by definition, all this kind of predicate can do is encompass the current ref- erence point without updating it. Finally, although the use of the pluperfect in the main clause imposes the anteriority of the action it denotes, we argue that the pluperfect focuses on the resulting state which includes the reference point and produces the effect of simultaneity.
THE EFFECT OF EMOTIONAL INTELLIGENCE ON LEADERSHIP ORIENTATION
Authors: Muştu Damla , Kaya Esra
Published: January 2022

Purpose: Teachers have exceeded the traditional teaching role and are now recognized as leaders who initiate and administer institutional change and renovation, and guide students within and beyond the classroom. The successful execution of this new leadership role that teachers have assumed requires teachers to be raised as potential leaders prior to their professional lives. This, in turn, necessitates the determination of the components that influence prospective teachers’ leadership orientations along with a better understanding of the nature of leadership. The main purpose of this study is to determine the influence of emotional intelligence on leadership orientations of first year students of the Anadolu University Education Faculty. Research method: Relational screening model is used to determine the relation between leadership orientation and emotional intelligence. The target population of this relational screening model study consists of first year students (n=854) studying at the Education Faculty of Anadolu University. Data from over 476 (56%) questionnaires was analyzed. Descriptive statistics and structural equation modelling were used for data analysis. Findings: The findings indicated a middle level significant linear relationship (r=0.59; p<0.001) between leadership and emotional intelligence. Implications for Research and Practice: In accordance with these findings, it is suggested that to increase leadership in education, programs supporting the development of emotional intelligence should be incorporated into teacher education programs.

Multiple irregularities and thrombus in a patient with COVID-19 presenting with ST-segment elevation myocardial infarction: a case report
Authors: Shah Bhupesh , Shah Harshal , Shah Darshil
Published: January 2022

Background: Multiple thrombi are likely to develop in Coronavirus Disease 2019 (COVID-19) patients. Hence, achieving successful outcomes following catheterization becomes quite challenging in such patients.

Case presentation: We report a challenging case of a 36-year-old female with ST-Segment Elevation Myocardial Infarction (STEMI). Coronary angiography revealed multiple irregularities in the coronary tree as well as thrombi. Although computed tomography imaging of the thorax was normal, reverse transcription-polymerase chain reaction (RT-PCR) confirmed the diagnosis of COVID-19. The outcome was good TIMI flow after a successful Primary Angioplasty in Acute Myocardial Infarction (PAMI), and the patient was isolated and then switched to oral anticoagulants (clopidogrel) for dual antiplatelet therapy (DAPT) therapy. 

Conclusion: This case emphasizes the management of a COVID-19 patient for PAMI.
Hyperferritinemia: the link between COVID-19, inflammation, and patient comorbidities
Authors: Lazar Angela Madalina
Published: January 2022

Ferritin is a key molecule in iron metabolism, as it stores the iron in a non-toxic form for the cells. Serum ferritin is a parameter that reflects the iron content of the body. However, serum ferritin is also an acute-phase reactant protein, as increased levels of serum ferritin are reported in many diseases associated with inflammation. Hyperferritinemia was also reported in COVID-19 (the coronavirus disease 19) patients, where it is considered an independent prognostic factor for the patients, indicating increased severity of the disease, risk for complications, and death. Certain categories of patients (older, those with comorbidities) have an increased risk of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infectivity and developing more severe forms of COVID-19. Chronic/acute systemic inflammatory states often characterize such preexisting comorbidities. In the current paper, a new pathogenic link is proposed and analyzed: between preexisting hyperferritinemia in the context of patient comorbidities (metabolic, cardiovascular, kidney, inflammatory, autoimmune, cancer) and the risk of SARS-CoV-2 infectivity and of developing more severe forms of infection. Ferritin per se can be a causal agent in COVID-19, as it can generate and aggravate inflammation and contributes to the development of a severe cytokine storm. A severe, uncontrolled inflammatory state occurs, triggered by the high levels of serum ferritin, preexisting comorbidities, and SARS-CoV-2 infection, cause of lethality in many patients. The inflammatory stimuli can further aggravate the infection by activating ADAM-17 (disintegrin and metalloprotease 17), a key enzyme involved in ACE2 (angiotensin-converting enzyme 2) activation and viral infectivity. In this context, iron chelators and antioxidants could become potential lines of treatment in COVID-19.

Alms is a gift given by someone in the form of property or non-treasury with the aim of expecting the pleasure of Allah SWT. Indonesia is a country with a relatively high percentage of poor people. As a country with a majority Muslim population, the potential for alms is very large. Alms in large amounts can be an alternative instrument in reducing poverty in Indonesia. One of the humanitarian agencies that collects alms funds is Aksi Cepat Tanggap (ACT) Bogor branch. The development of technology and information has made it easier for ACT to develop an online-based alms fundraising strategy. The purpose of this study was to determine the effectiveness of online alms fundraising at ACT Bogor branch. The research method used is qualitative descriptive with data collection techniques of observation, interviews and documentation. The results showed that in 2020 ACT Bogor branch was not effective in terms of effectiveness ratio because it was only able to raise funds of Rp. 4,448,517,958 with the target set by the institution of IDR 7,000,000,000,000. This is because the target set by the institution is very high, even though the collection of funds is quite large. Progressive results can be said to be effective because online-based alms fundraising is very optimal during a pandemic when compared to direct fundraising because it is constrained by restrictions on community activities by the government during the pandemic. The online alms fundraising mechanism is considered easier and very supportive during the COVID-19 pandemic. With the online-based alms fundraising, it is hoped that ACT branches will be able to increase the collection of alms funds from donors and in the future, ACT Bogor Branch will have its own application specifically made to collect alms-based alms online so that the obstacles that often occur can be minimized.

We investigated the meaning of work of young adults transitioning from vocational education and training to employment. Meaning of work was operationalized as the combination of work centrality and purposes. Sixty-four young adults were interviewed at the end of vocational education and training and after their integration into the labor market. Qualitative analyses indicated that the centrality of work ranged from high to low and that their work purposes were of five types: earning money, growing, structuring life, contributing to society, and socializing. Quantitative analyses showed that the meaning of work globally did not change through the transition process, and work had a higher relative centrality for men than for women. These results stress the importance of considering the variety of functions and degrees of importance young adults confer to work when entering the labor market as well as integrating the concept of work meaning within counseling research and interventions.

A new parameter of metabolic control derived from the results of continuous blood glucose monitoring is time in range (TIR). According to current recommendations, in pregnant women with diabetes, this glycemic range is defined by values of 3.5 to 7.8 mmol/L, with the aim of keeping glycemia in this range as much time as possible, and at the same time reducing the time spent below its lower limit (< 3.5 mmol/L). In pre-gestational type 1 diabetes, it is recommended to reach this TIR above 70% of the total measurement time including up to 4% of simultaneous time spent in hypoglycemia. In gestational (and pre-gestational type 2) diabetes, the recommended % of in-range times are not yet specified. Key words: continuous monitoring glucose – gestational diabetes – glycemic control – time in range

Objective: Overview of current knowledge in the field of the endocannabinoid system with emphasis on the relationships between endocannabinoids and exocannabinoids. The endocannabinoid system consists of cannabinoid receptors 1 and 2, ligands of these receptors, especially two "classical" endocannabinoids N-arachidonoylethanolamine (anandamide) and 2-arachidonoyl-glycerol. Transport systems that ensure the entry of endocannabinoids into cells, where they are degraded by fatty acid amide hydrolase or monoacylglycerol lipase. The endocannabinoid system is a signaling pathway for the regulation of a number of physiological or pathological conditions. So far, it is one of the less explored ways of regulation, as evidenced by the recent explosive increase in the number of published works. Dysregulation of endocannabinoid systems is a possible cause of many diseases. It can occur both in the genetic polymorphism of its individual components, but also in therapy with certain drugs or natural substances, typically cannabinoids. Due to the wide overlap of the regulation of physiological functions by the endocannabinoid system, a considerable number of drugs are being developed, the aim of which is to correct the dysregulation of the endocannabinoid system. Conclusion: The endocannabinoid system is one of the most important regulatory systems with a very broad intervention in physiological and pathological conditions. The resulting specific regulations intersect the interplay of many enzymes involved in the production and degradation of endocannabinoids, transport systems involved in the entry of endocannabinoids into cells, cannabinoid receptors and exogenous cannabinoids, or natural substances acting at various sites in the endocannabinoid system. Knowledge in this area can contribute to improving health care and increasing the safety of its provision. Key words: endocannabinoids – anandamide – 2-arachidoyl glycerol – cannabinoid receptor – fatty acid binding proteins – fatty acid amide hydrolases – lipase for monoacylglycerols – cannabinoids
