Towards A Radically Relational Post-Grotowskian Performance Paradigm
Authors: Magnat Virginie
Published: December 2023

Jerzy Grotowski chose to name his College de France lecture series La „lignee organique” au theatre et dans le rituel (The „Organic Lineage” in Theatre and Ritual), and the author, who attended and documented these final public talks, contends in this article that organicity constitutes a through-line connecting Grotowski’s theatrical and post-theatrical research. The author draws from these talks, as well as from her Grotowski-based training, including her work with Rena Mirecka, and her research collaborations with Indigenous artists and scholars from Turtle Island (North America), including Floyd Favel, who worked with both Grotowski and Mirecka. The author points out that in diverse traditional cultural practices whose role it is to enhance, restore, and sustain balance between human and non-human forms of life, organicity is understood as a living force endowing performative processes with energy, power, and efficacy. The post-Grotowskian performance paradigm envisioned by the author hinges upon a non-anthropocentric perspective informed by the ecological and spiritual dimensions of relationality articulated by several generations of Indigenous scholars. She contends that such a paradigm shift, which challenges artistic practices glorifying human creative agency, can provide a viable alternative to the dominance of (Eurocentric) new materialist/posthumanist theories of non-human agency.

Marketing management system of agricultural enterprises
Authors: Potapiuk Iryna
Published: December 2023

Transforming the essence of marketing activity, determining its role and place in the enterprise management system, and filling the concept of marketing management with new content is due to radical changes in the system of global market relations. Today, profound changes are taking place in management and marketing under the influence of the transformation of world economic processes. From an ordinary function, the latter turns into the main integrating one and occupies a leading position in the management hierarchy. Traditional management has been replaced by marketing management. Agricultural enterprises still need to use the advantages of marketing management. It is noted that the marketing management of an agricultural enterprise reduces the influence of environmental factors. Factors of trends influencing the marketing management system of an agricultural enterprise are determined. The model of the enterprise's marketing management system is singled out as a complex mix of defined subjects, objects, management methods, and tools for their implementation, which, closely interacting with each other, ensure effective marketing management of the enterprise. It is emphasized that effective marketing management of agricultural enterprises helps to identify profitable opportunities and obtain the most complete customer satisfaction. The process of marketing management is considered a specific algorithm of actions and operations to achieve the company's intended goals. To form this process for a specific enterprise, it is necessary to consider its characteristics. The author's vision of the definition of the concept "marketing management system of agricultural enterprises" is given. The use of marketing management will contribute to ensuring the market orientation of an agricultural enterprise, which involves targeting success, timely adaptation to the external environment, increasing the level of competitiveness of enterprises, and improving their financial and economic results.

Matrix metal collimators studies for the spatially fractionated radiation therapy
Authors: Anokhin I. , Ramazanov D.
Published: December 2023

Traditional radiation therapy is hindered by limitations in dose delivery and the risk of over-irradiation, which can harm healthy tissues surrounding tumors. Spatially fractionated and intensity-modulated radiation therapies have emerged as promising techniques to mitigate these issues by reducing damage to healthy tissues. This study explores the potential of enhancing radiation therapy's therapeutic efficacy through spatial fractionation of X-ray beams, a technique that can significantly increase radiation efficiency by reducing the dose load on healthy tissues. This research hypothesizes that microscopic lesions within the paths of micro/mini-beams can be repaired by minimally irradiated cells adjacent to the irradiated tissue slices, based on observations with high-energy (MV) photons. Spatial fractionation is particularly valuable for X-ray and electron radiation therapy, which is more widespread and cost-effective than proton therapy. The study introduces a new type of cost-effective metal matrix collimators designed for beam fractionation. These collimators are constructed using lead plates for thickness variation implementation and employ a 5x5 hole matrix with 1 mm diameter and 3 mm pitch, covering an area of 14x14 mm². To visualize beam distribution, a Timepix detector, capable of providing real-time 2D beam profiles, was employed. Experiments were conducted using a medical LINAC with typical therapeutic energy ranging from 6 to 18 MeV. Results indicate that spatial fractionation can be achieved for X-ray radiation, with a PVDR of approximately 3 for a 3 cm lead collimator. However, issues with hole uniformity and blurring in the peak area prompted a shift to using copper collimators due to their superior manufacturing properties. This study presents a novel matrix collimator design made from various materials for shaping mini beams, aimed at improving the efficiency of spatial dose fractionation for different ionizing radiation types. Geant4 simulations have been instrumental in optimizing collimator features. The findings suggest that high levels of dose fractionization can be achieved for X-rays, electrons, and proton beams. These results warrant further biological studies to evaluate the effects of fractionation on normal and tumoral tissues, supporting the practical implementation of collimation in radiation therapy.

Authors: Struk І. , Yurchak I.
Published: December 2023

The purpose of this work is to conduct a study of computer steganography methods and the implementation of image steganography using the LSD algorithm and the Caesar cipher. The development of global computer networks allows fast and efficient transfer of electronic documents, but at the same time there is a risk of illegal copying and distribution of materials. Confidentiality of important information is an extremely responsible matter. Therefore, there is a need to develop methods and software tools for hiding information in various types of files, in particular images. Steganography is a mechanism for hiding messages in cloaking objects such as images, audio, text, video, and network protocol so that the hidden message cannot be detected by the naked eye or attackers

Authors: Asshilah Adelia Nur , Hasan Zainudin
Published: December 2023

During this Covid-19 pandemic, many problems have been found that have been faced by health workers in carrying out health service tasks that have the potential to not guarantee legal certainty. The purpose of this study was to determine the factors causing criminal acts by health workers during the Covid-19 pandemic. The research method used is a normative juridical approach by collecting data from literature studies. Based on the research that has been done, it is found that health workers may experience crime from the community, which occurs due to several factors. Pancasila has an ideology and philosophical basis so the principle of legal protection for the Indonesian people is the principle of recognition and protection of human dignity based on Pancasila and the principle of the rule of law based on Pancasila. In other words, the concept of legal protection is an illustration of the function of law, namely the concept that the law provides justice, order, certainty, benefit, and peace. Legal protection for health workers during the COVID-19 pandemic consists of preventive protection efforts and repressive protection efforts. Preventive Protection which is defined as prevention, in other words, is the freedom to act because of the content contained in the legislation to prevent a violation. Repressive Protection serves to solve problems. This protection is in the form of sanctions for violations committed.Keywords: Health Workers, Crime Factors

The World Health Organization suggests treating tuberculosis with a 6-month course of isoniazid (INH), rifampicin (RMP), ethambutol, and pyrazinamide. The anti-TB activity of a number of novel styryl-1,2,4-oxadiazoles against the MTB H37Ra strain was assessed. These compounds were motivated by the molecular structure of cinnamic acid. There is a substantial correlation between the antibacterial activity and the location of the pyridine substituent on the thiosemicarbazide skeleton. A total of thirty-three ligands were docked against the two proteins AftaA and EmbA during the primary protein-ligand docking process, which was carried out using iGemDock. The following study included eight anti-tuberculosis medications as a control group: rifampicin, isoniazid, bed aquiline, delamanid, ethionamide, ethambutol, Gemifloxacin, and thioacetazone.

Published: December 2023

The article examines the peculiarities of innovative development of enterprises of the agro -industrial complex of Ukraine in modern conditions. Innovations are considered as one of the factors of economic development at all levels as the motivator of its productivity and competitiveness.

It was determined that the economic categories of innovative activity and intellectual capital are closely related. Key aspects are highlighted, which are the motivator of innovative development of enterprises and factors that have a positive and negative impact on the introduction of innovations at the enterprises of the agro -industrial complex.

The classification of types of innovations was considered, global trend directions and priorities of innovative development for domestic representatives of the agricultural sector were highlighted, their practical use according to each type is analyzed.

The domestic experience of innovative development of the agrarian sector of the Ukrainian economy was analyzed and it was found that individual holdings and enterprises chose an innovative path of development that contributes to improving productivity and labor efficiency. In particular, it is emphasized that innovative development is an irreplaceable source of sustainable development of agricultural enterprises in modern conditions, which, in turn, strengthens the position of agrarian enterprises in the domestic market and allows them to compete on the world markets.

The types of innovations were studied, which made it possible to assess the diversity of approaches to the innovative development of agricultural enterprises. The activity of agricultural enterprises according to special aggregations was analyzed. Three main priorities of the innovativeness of domestic agrarian activity are highlighted: precision farming, innovations in field accounting and analysis, and the company's management system.

The creation of the Innovative Center of Agrarian Education and Development (ICAED) is proposed to promote the unification of the efforts of institutions of higher education, agro-enterprises and innovative structures in order to activate innovations in AIC, as well as to adapt educational disciplines to modern market needs. It was determined that the renewal of innovative infrastructure and improvement of connections between education, science and agribusiness require attention.

Authors: DOTSIUK Svitlana
Published: December 2023

The article highlights the theoretical essence of the concept of «entrepreneurship» and reveals the views of domestic scientists regarding this term. The rights used by business entities are reflected. The peculiarities of the development of entrepreneurship in the agrarian sphere are clarified, namely: the seasonal nature of production, an increase in the share of traditional goods and services, interaction with agricultural producers, the unique role of land as a production factor, and the creation of new opportunities for employment of the unemployed rural population. An equally important feature is that the economic process of reproduction is always closely intertwined with the natural one.

The importance of signing the Association Agreement between Ukraine and the European Union, which creates an opportunity for business entities to produce products and look for better options for their implementation on the European market, is substantiated.

The monthly dynamics and current state of the export of products were analyzed and appropriate conclusions were drawn regarding the factors that had a significant impact on the decrease of Ukrainian exports in 2022. The analysis of the export of agricultural products in 2022 by category was carried out and the ranking of the countries to which Ukraine exported the most grain crops was displayed.

The importance of the use of sea transport, in which business entities are able to reduce costs for the delivery of Ukrainian agricultural products to the countries of the European Union and other countries, is noted.

The article presents the importance of signing the Black Sea Grain Initiative, also known as the «grain agreement», which consists of two separate agreements with different contents: between the russian federation and the United Nations (hereinafter - the UN) with the participation of Turkey; between Ukraine and the UN with the participation of Turkey. The agreement gives our country the opportunity to export grain crops by sea transport, since the russian federation has taken responsibility not to attack the port infrastructure of Chornomorsk, Odesa and Yuzhnoye. However, in October 2022, the russian federation suspended its participation in the agreement.

Published: December 2023

The present paper is a sequel to the paper on the topic with Kerr law nonlinearity. For power-law nonlinearity, it was derived through balancing principle that the solitons would exist for two values of the power-law parameter,  namely n = 1 or n = 2. The current paper derives dark and singular solitons for the latter value of n since the first case was already covered in a previous report that was dedicated to address the model with Kerr law.
Berries without Bugs: Recreational Foraging and a Fruit Fly Threat in Rural Michigan
Authors: Bal Tara L. , Beaudoin Siona M. , Carter Angie
Published: December 2023

Recreational foraging is an important cultural activity in the rural region of Michigan’s Upper Peninsula. During the summer of 2019, an exploratory survey was conducted of foragers in the Keweenaw Peninsula area of Michigan’s Upper Peninsula to identify local knowledge
of berries and a new invasive fruit fly, spotted wing drosophila (SWD, Drosophila suzukii). SWD infests fruit before it is harvested, hastening ripening and potentially causing the fruit to spoil more quickly than might be expected. Research studying recreational foraging in the US
has primarily focused on the study of urban areas. In addition, research studying SWD???s impact on berry production has largely focused on commercial cultivation rather than foraged harvesting in mixed woodlands. The majority of our respondents began picking berries in their youth and have
continued throughout their life, emphasizing the importance of berry foraging within the local culture. Furthermore, many of the respondents confirmed that they pick berries as a cost-saving way to obtain healthy food, which could negatively be impacted by the fruits spoiling more quickly.
In conclusion, most respondents were unfamiliar with SWD. Our findings suggest additional research studying the cultural and economic impacts of SWD is needed to inform adaptive foraging practices and SWD infestation prevention.

To study the effect of 50% ethanol extract of Bougainvillea xbuttiana on the enzymatic activity, cell viability and cytokine production provoked by the venom of Bothrops jararacain macro-phages. Three assays were used to study the effects of B. xbuttiana extract on the damage produced by B. jararaca: Enzymatic activity was detected by measuring the proteolytic and phos-pholipase A2; macrophages cytotoxicity was determined by the MTT method; levels of cytokine were evaluated using ELISA and a biological assay. After treatment with 300 μg/mL B. xbuttiana extract for 30 min, the proteolytic and phospholipase A2 activities of the venom were reduced to 95 and 61%, respectively. In macrophages cultures treated with B. xbuttiana extract combined with venom, the production of TNF-α, IL-6 and IFN-γ was reduced, whereas IL-10 was potentiated. Our results support the potential effect of the B. xbuttiana extract as a complementary therapy against the toxicity caused by the venom of B. jararaca snakes.

Authors:   Institute of Socio-Economic and Energy Problems of the North, Komi Science Centre, Ural Branch of the Russian Academy of Sciences, Terentyeva Marina A.
Published: December 2023

This article explores employment in the informal sector across Russian northern regions and studies factors that affect the employment rate in this sector. The research aims to examine various facets of this subject, encompassing the role of informal employment in job creation. Drawing on data from international organizations, domestic research, and statistics, the study reveals the significant role played by the informal sector in the country's economy. Utilizing a production approach, the article analyzes the structure of informal employment in the northern regions of Russia and identifies three groups of factors influencing employment rates. For these three groups, indicators were chosen that formed the basis for the analysis of employment trends in the informal sector. Using official statistics for 2005-2022 while considering the comparability of data collection and processing methods, the study assesses the level of informal employment in northern regions and studies how it is influenced by the economic factors under question. Despite a high Gross Regional Product (GRP) per capita, the study reveals that existing institutions do not contribute to the population settling in the North. The article highlights variations in informal employment rates. It underscores the importance of stimulating sector formalization, improving the quality of life in the North, and supporting economic growth. The study's results can inform regional policies addressing employment and social services.

Published: December 2023

Over the years, climate change has generated an increase in the average temperature of the planet, which has led to greater consumption of electrical energy for the use of air conditioning systems. Insulating envelope materials are considered a viable passive solution as they offer internal air conditioning, cooling, and/or heating of buildings that lead to thermal comfort with reduced energy consumption. This article compares the application of different insulating materials in an existing single-family home located in a hot-dry climate. To this end, the procedural methodology has been applied by carrying out a bibliographic review of different involutes currently used in the construction of the buildings and 14 models are proposed that will be simulated under the same input variables of the base model and meteorological data of the city of Bucaramanga validated from a meteorological station located on site. The results of the simulations show that all 14 models show a decrease in temperature with reference to the "base model"; This difference can be explained by the presence of the selected materials that slightly change the thermal properties of the wall. Finally, this research allowed us to determine that the occupants of the simulated spaces in the base model are inside the thermal comfort range by 61.96%, which represents 5,438 hours of the modeled year, having 38.03% of hours of discomfort in the measured time. This study can be useful for the selection of envelopes and different buildings with passive cooling requirements.

Motion Capture Algorithm for Students' Physical Activity Recognition in Physical Education Curriculum
Authors: Lu Yinfu , Long Haitao
Published: December 2023

Physical training learning is one of the important ways to raise the national physical quality and health level. However, there are many problems in traditional physical education, such as the difficulty to identifying the effectiveness of physical education curriculum and low level of repetitive exercise content. In order to solve this problem and improve the curriculum quality of current middle school physical education courses, a motion capture algorithm based on convolutional neural network and long-term memory network is proposed, and a student physical activity capture model is constructed based on the fusion algorithm. In the performance comparison test of the fusion algorithm proposed in this study, the loss value and accuracy of this fusion algorithm are 0.045 and 0.921, respectively, significantly superior to the comparison algorithm. Then in the empirical analysis, the accuracy rate of this motion capture algorithm model proposed in this study for students' walking posture recognition in physical education courses is 91.5%, which is better than the comparative capture method. This motion capture algorithm can accurately capture the physical activities of students in physical education courses, which has practical application significance.

Breathing with Seagrass
Authors: Kortekallio Kaisa
Published: December 2023

This essay introduces recent speculative novels written by Finnish authors and discusses the vegetal agency that permeates them. In Johanna Sinisalo’s
The Core of the Sun
(2013; translated 2016) and Emmi Itäranta’s
The Moonday Letters
(2020; translated 2022), plant life entices, intoxicates, and transforms human bodies and minds. Sinisalo experiments with ideas about the coevolution of plants and humans, and Itäranta explores the significance of plants in the contexts of space colonies and ecosabotage. The essay suggests that the novels gesture toward an emerging
Planthroposcene
. Anthropologist Natasha Myers has proposed “Planthroposcene” as a modification to Anthropocene, the era of global human impact on the Earth. As an “aspirational episteme,” the Planthroposcene considers plants as allies and teachers, and invites researchers and artists to develop ways of “conspiring” with them. While the Planthroposcene invites humans to align themselves with plant life in mutually beneficial relationships, contemporary Finnish speculative fiction suggests that such relationships are not fluid extensions of knowledge, but can also be strange, disturbing, and even destructive. Drawing on the theoretical view that speculative fiction can challenge readers’ habitual patterns of engaging with their lived environments, and thus give rise to unexpected experiences and non-anthropocentric viewpoints, the essay develops the notion of
embodied estrangement
. Discussing ambivalent plant–human relations demonstrates how the notion of embodied estrangement can contribute to science fiction studies as well as to more-than-human methodologies in literary studies.

(2018) fuses speculative fiction’s project of cognitive estrangement with sentimental literature’s project of dispersing ethically charged affective experience. The resulting mode of narrative, what I term posthumanist sentimentality, estranges readers from established forms of both thought and feeling, opening them to models of care that operate in more-than-human worlds. Entangling the traumatic account of the eponymous posthuman creature with the romantic history of the humans who made her,
The Strange Bird
highlights both the dangers of anthropocentrism and the values of radical ontological vulnerability when learning to witness for and with posthuman and post-traumatic subjects.
Newton's Off-Center Circular Orbits and the Magnetic Monopole
Authors:   Texas A&, Bhandari Dipesh ,   M University-Commerce, USA, Crescimanno Michael ,   Youngstown State University, USA
Published: December 2023

Introducing a radially dependent magnetic field into Newton's off-center circular orbits potential so as to preserve the $E=0$ dynamical symmetry leads to a unique choice of field that can be identified as the inclusion of a magnetic monopole in the inverse stereographically projected problem. One finds also a phenomenological correspondence with that of the linearly damped Kepler model. The presence of the monopole field deforms the symmetry algebra by a central extension, and the quantum mechanical version of this algebra reveals a number of zero modes equal to that counted using the index theorem of elliptic operators.

The presence of tidal deformations in close binary stars has already been confirmed by astronomical observations. The present paper aims to simply address an astronomy problem, studying the relative movement of close binaries disturbed by their mutual deformation through some basic concepts and tools of celestial mechanics. For this purpose, the tidal effect is modeled by considering that each star is an elongated revolution ellipsoid in such a way that axes of revolution are coincident, and their largest axes point toward each other along the motion. The potential for mutual attraction is then obtained, resulting in a perturbed Keplerian system with perturbation proportional to the inverse of the cubic distance between the stars, thus being a one-degree-of-freedom problem and, therefore, integrable. The effective potential, the integrals of energy and angular momentum, and the Laplace vector are used to obtain qualitative information about the dynamics before integrating it. The motion describes a rosette-like orbit with periodic osculating elements, or a circle when the energy is a local minimum. Finally, an analytical solution is presented in terms of elliptic functions by using a regularizing and linearizing function.
H i in Molecular Clouds: Irradiation by FUV Plus Cosmic Rays
Authors: Sternberg Amiel , Bialy Shmuel , Gurman Alon
Published: December 2023

We extend the analytic theory presented by Sternberg et al. and Bialy & Sternberg for the production of atomic hydrogen (H i) via far-ultraviolet (FUV) photodissociation at the boundaries of dense interstellar molecular (H2) clouds to also include the effects of penetrating (low-energy) cosmic rays (CRs) for the growth of the total H i column densities. We compute the steady-state abundances of the H i and H2 in one-dimensional gas slabs in which the FUV photodissociation rates are reduced by depth-dependent H2 self-shielding and dust absorption and the CR ionization rates are either constant or reduced by transport effects. The solutions for the H i and H2 density profiles and the integrated H i columns depend primarily on the ratios I
UV/Rn and ζ/Rn, where I
UV is the intensity of the photodissociating FUV field, ζ is the H2 CR ionization rate, n is the hydrogen gas density, and R is the dust surface H2 formation rate coefficient. We present computations for a wide range of FUV field strengths, CR ionization rates, and dust-to-gas ratios. We develop analytic expressions for the growth of the H i column densities. For Galactic giant molecular clouds (GMCs) with multiphased (warm/cold) H i envelopes, the interior CR zones will dominate the production of the H i only if

The nearby dwarf galaxy POX 52 at z = 0.021 hosts an active galactic nucleus (AGN) with a black hole (BH) mass of M
BH ∼ 105–6
M
⊙ and an Eddington ratio of ∼0.1–1. This object provides the rare opportunity to study both AGN and host-galaxy properties in a low-mass highly accreting system. To do so, we collected its multiwavelength data from X-ray to radio. First, we construct a spectral energy distribution, and by fitting it with AGN and host-galaxy components, we constrain AGN-disk and dust-torus components. Then, while considering the AGN-disk emission, we decompose optical Hubble Space Telescope images. As a result, it is found that a classical bulge component is probably present, and its mass (M
bulge) is consistent with an expected value from a local relation. Lastly, we analyze new quasi-simultaneous X-ray (0.2–30 keV) data obtained by the Nuclear Spectroscopic Telescope Array and XMM-Newton. The X-ray spectrum can be reproduced by multicolor blackbody, warm and hot coronae, and disk and torus reflection components. Based on this, the spin is estimated to be a
spin = 0.998−0.814, which could suggest that most of the current BH mass was achieved by prolonged mass accretion. Given the presence of the bulge, POX 52 would have undergone a galaxy merger, while the M
BH–M
bulge relation and the inferred prolonged accretion could suggest that AGN feedback occurred. Regarding the AGN structure, the spectral slope of the hot corona, its relative strength to the bolometric emission, and the torus structure are found to be consistent with Eddington-ratio dependencies found for nearby AGNs.

We present a methodology for modeling the joint ionizing impact due to a “simple X-ray population” (SXP) and its corresponding simple stellar population (SSP), where “simple” refers to a single age and metallicity population. We construct composite spectral energy distributions (SEDs) including contributions from ultraluminous X-ray sources and stars, with physically meaningful and consistent consideration of the relative contributions of each component as a function of instantaneous burst age and stellar metallicity. These composite SEDs are used as input for photoionization modeling with Cloudy, from which we produce a grid for the time- and metallicity-dependent nebular emission from these composite populations. We make the results from the photoionization simulations publicly available. We find that the addition of the SXP prolongs the high-energy ionizing output from the population—and correspondingly increases the intensity of nebular lines such as He ii
λ1640,4686, [Ne v] λ3426,14.3 μm, and [O iv] 25.9 μm by factors of at least two relative to models without an SXP spectral component. This effect is most pronounced for instantaneous bursts of star formation on timescales >10 Myr and at low metallicities (∼0.1 Z
⊙), due to the imposed time- and metallicity-dependent behavior of the SXP relative to the SSP. We propose nebular emission line diagnostics accessible with JWST suitable for inferring the presence of a composite SXP + SSP, and we discuss how the ionization signatures compare to models for sources such as intermediate-mass black holes.
Stellar Neutrino Emission across the Mass–Metallicity Plane

Published: December 2023

We explore neutrino emission from nonrotating, single-star models across six initial metallicities and 70 initial masses from the zero-age main sequence to the final fate. Overall, across the mass spectrum, we find metal-poor stellar models tend to have denser, hotter, and more massive cores with lower envelope opacities, larger surface luminosities, and larger effective temperatures than their metal-rich counterparts. Across the mass–metallicity plane we identify the sequence (initial CNO → 14N → 22Ne → 25Mg → 26Al → 26Mg → 30P → 30Si) as making primary contributions to the neutrino luminosity at different phases of evolution. For the low-mass models we find neutrino emission from the nitrogen flash and thermal pulse phases of evolution depend strongly on the initial metallicity. For the high-mass models, neutrino emission at He-core ignition and He-shell burning depends strongly on the initial metallicity. Antineutrino emission during C, Ne, and O burning shows a strong metallicity dependence with 22Ne(α, n)25Mg providing much of the neutron excess available for inverse-β decays. We integrate the stellar tracks over an initial mass function and time to investigate the neutrino emission from a simple stellar population. We find average neutrino emission from simple stellar populations to be 0.5–1.2 MeV electron neutrinos. Lower metallicity stellar populations produce slightly larger neutrino luminosities and average β decay energies. This study can provide targets for neutrino detectors from individual stars and stellar populations. We provide convenient fitting formulae and open access to the photon and neutrino tracks for more sophisticated population synthesis models.
