description: Στην παρούσα διπλωματική εργασία παρουσιάζεται το φαινόμενο του φανατισμού στους χώρους της Θρησκείας και της Πολιτικής. Ιδιαίτερα εξετάζεται, μία από τις πιο ακραίες μορφές ζηλωτισμού, η θεσμοποίηση της ουτοπίας, η οποία αποτελεί υπόστρωμα του θρησκευτικού και του πολιτικού φανατισμού. Θρησκευτικές ομάδες και Πολιτικά κινήματα που υποπίπτουν σε αυτού του είδους τις εξτρεμιστικές τάσεις, διαθέτουν ένα Μανιχαϊκό διπολισμό, καθώς αντιμετωπίζουν τους εαυτούς τους ως εκλεκτούς της ανθρωπότητας, ενώ αντίθετα τους εχθρούς τους, ως αμαρτωλούς και «ακάθαρτους». Εκφράζοντας έντονα χαρακτηριστικά Μεσσιανισμού, εξωθούνται στη βία, πραγματοποιούν ένοπλους αγώνες και ασκούν τρομοκρατία, με σκοπό την επιβολή της πίστης ή της ιδεολογίας τους, ώστε να εγκαθιδρύσουν στην κοινωνία την τέλεια ειρήνη και δικαιοσύνη. Μέσω αυτού του φαινομένου που ιεροποιείται η βία, απαξιώνεται το ανθρώπινο πρόσωπο και διαταράσσεται η κοινωνική συνοχή, εξετάζονται και οι περιπτώσεις αυτού στην Ιστορία, τόσο στο χώρο της Θρησκείας όσο και στον χώρο της Πολιτικής. Τέλος, αναλύεται η αντιμετώπιση ενός τόσο αρνητικού κοινωνικού φαινομένου από την οπτική της Ορθόδοξης Παράδοσης και Διδασκαλίας. Ο Χριστιανισμός και η Ορθόδοξη Εκκλησία επιδιώκουν ενεργά να μεταφέρουν τα μηνύματα της ανιδιοτελούς Αγάπης και του διαλόγου, με σκοπό την οικοδόμηση των ανθρώπινων σχέσεων και όχι την καταστροφή αυτών, όπως πράττει ο φανατισμός
description: In the present thesis, is introduced the phenomenon of fanaticism in the fields’ of Religion and Politics. Especially, is analyzed one of the most extreme forms of zealotry, the institutionalization of utopia, which is the foundation of religious and political fanaticism. Religious groups and Political movements that follow that kind of extreme tendencies, possess a dualistic cosmology as Manichaeism, facing themselves as the elite of humanity, but their enemies as immorals and sinners. Tending to Messianic actions, they are leading to violence, armed struggles and terrorism, in order to force their belief or ideology and establish the ideal peace and justice in society. Through this phenomenon, in which violence is being sanctified, human identity is being disdained and the social cohesion is being disturbed, are analyzed the cases which through History took place in Religious and Political fields. In conclusion, is examined the facing of a such negative social phenomenon from the perspective of the Orthodox Tradition and Teaching. Christianity and the Orthodox Church actively endeavor to deliver the messages of unconditionall Love and dialogue, in order to construct human relations and not to destroy them, like in fanaticism

description: We utilize a novel numerical technique to model star formation in cosmological simulations of galaxy formation - called Superstars - to simulate a Milky Way-like galaxy with $\gtrsim10^8$ star particles to study the formation and evolution of out-of-equilibrium stellar disc structures in a full cosmological setting. In the plane defined by the coordinate and velocity perpendicular to the mid-plane (vertical phase space, $\{Z,V_Z\}$), stars in Solar-like volumes at late times exhibit clear spirals qualitatively similar in shape and amplitude to the $Gaia$ ``Snail shell'' phase spiral. We show that the phase spiral forms at a look back time of $\sim 6$ Gyr during the pericentric passage of a $\sim10^{10}$ $\rm M_{\odot}$ satellite on a polar orbit. This satellite stimulates the formation of a resonant wake in the dark matter halo while losing mass at a rate of $\sim0.5$-$1$ dex per orbit loop. The peak magnitude of the wake-induced gravitational torque at the Solar radius is $\sim 8$ times that from the satellite, and triggers the formation of a disc warp that wraps up into a vertical phase spiral over time. As the wake decays, the phase spiral propagates several Gigayears to present-day and can be described as ``ever-present'' once stable disc evolution is established. These results suggest an alternative scenario to explain the $Gaia$ phase spiral which does not rely on a perturbation from bar buckling or a recent direct hit from a satellite.

Is there a downside to gender equality? A trend analysis of structural gender equality and gender differences in adolescent mental health (2002 -2022)

subject: gender inequality

description: Recent evidence points to an increase in mental health problems and a decrease in positive mental health (i.e., life satisfaction) in adolescents, particularly among girls, over the past decades. These trends are more consistent in Western (European) countries than elsewhere and seem to be related to increases in schoolwork pressure, internet use and obesity, among other factors. Given the relatively strong increase in the gender gap in mental health problems, with girls experiencing progressively worse outcomes than boys, and cross-national variation in this respect, structural drivers of these trends at the national level should be further examined. Paradoxically, it has been argued that in recent years, alongside a wide range of benefits, gender equality places particular pressure on girls, as it might intensify the pressure to succeed simultaneously in multiple aspects of life: physically, socially and academically. In contrast, gender equality might have relaxed these pressures on boys. We hypothesize that gender equality at a societal level precipitates a widening of the gender gap in mental health in adolescents. Evidence on this topic is scarce and inconsistent, with a recent study suggesting that the gender-based inequality in adolescent mental health is larger in more gender-equal countries, with equality favouring boys more than girls. However, a slightly older study found a positive association between gender equality and mental health for both girls and boys. Moreover, previous studies did not consider trends in mental health, nor included variables on the individual or national level that may explain the increasing gender gap. This study will address the following research questions: 1. To what extent is (are) (increases in) gender equality on the national level associated with increases over time in a gender gap in adolescent mental health over the past 20 years? 2. Are these associations mediated by changes in schoolwork pressure, negative body image, or classmate support?

description: In previous work universal behavior was conjectured for the behavior of the logarithmic terms in the entanglement entropy of intervals in 1+1 dimensional interface conformal field theories (ICFTs). These putative universal terms were exhibited both in free field theories as well as a large class of holographic models. In this work we demonstrate that this same behavior in fact is realized in any holographic ICFT, significantly strengthening the case for the conjecture.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: Background- One of the common features in which the problems of children under difficult circumstances manifest is the problem of "streetism". There are an estimated 100 million street children worldwide, 150,000 in Ethiopia and 1,326 in Adama. Objective- To assess survival strategies of street children and their exposure to HIV/AIDS related risk factors in Adama town. Methods- A cross sectional descriptive study was conducted in Adama town. Both qualitative and quantitative study methods were used and interview using structured questionnaire and four FGDs were used to collect data. The study subjects for the quantitative study were selected by simple random sampling method after registering the street children. FGD participants were selected by using snowball technique. Result- A total of 998 street children aged above seven and less than eighteen completed years were registered and 441 have participated in the study. 77.1% of the respondents were males. Street children are engaged in different activities like petty trade, begging, theft, daily labor and commercial sex work to earn money. 86.5% of the study participants earn less than 10 ETH birr per day and the mean average daily income of study subjects is 1.19 ETH birr. Street children have admitted that they use alcohol and other substances like chat, cigarette, glue, benzene, shisha, hashish, atsefaris (cannabis), ganija, mixture of local leaves like "shewishewe" and "tikure", orange rind, and tea. 32.2% of the respondents are sexually active. 53.3% had their first sexual experience between the age of 10 and 14. 89.5% of respondents have heard of HIV/AIDS and 30.7% of the respondents consider themselves as having risk of being infected with HIV. 3.5% of respondents have had sexually transmitted diseases in their past history. It was also identified that there are males who are having sex with males and also street boys make sex with a single girl being in-group. vi Conclusion- The majorities of street children are living by their own being engaged in different activities. Because of luck of adult supervision and harsh environmental condition risky and unhealthy practices like substance use, early sex, violence and having multiple sexual partners are common. More should be done on child rights at all levels to protect children from joining streets and those who are on the street should be supported financially to decrease their vulnerability. Legislative actions should also be taken on drug traffickers.
title: Heterogeneity consideration in centrifuge experiments and simulations for capillary pressure curve measurements
Creators: name: Zhou, Guming
Publisher: name: Memorial University of Newfoundland

description: Capillary pressure curves are one of the most important inputs for reservoir characterization and modelling in oil and gas industry. Using centrifuge experiments for capillary pressure measurements is an efficient method for obtaining such curves. With the rapid development of modelling methods for centrifuge experiments, a challenge is now faced by researchers that the assumption of a one-dimensional and homogeneous core is required. The major objective of this research is to investigate the impacts of core-scale heterogeneity on phase saturation predictions by using a centrifuge simulation method that allows a two-dimensional fluid flow in the core. The streamline tracing method that considers capillary pressure numerically is applied to visualize and quantify effects of heterogeneity. Significant differences in phase saturation predictions have been observed between homogeneous and heterogeneous cores. For example, when a low permeability area is present in a core plug during a drainage centrifuge simulation, less wetting phase is displaced at some capillary pressure condition as compared to a homogeneous/randomly distributed core. Therefore, higher average saturations can be obtained and the maximum mean squared error of it is about 0.0013. A capillary pressure curve with a positive bias can be calculated and taken as an input for reservoir simulation to describe the distribution of reservoir fluids and the fluids contacts. When a high permeability area is present, the maximum mean squared error of the deviated saturation is 0.0004. This study revealed that it is necessary to consider core-scale heterogeneity in the modelling of centrifuge experiments since an inaccurate capillary pressure curve can produce results with considerable errors in reservoir simulations.
Assessing the Effect of Water PH on Turbidity Removal and Bacterial Load Reduction Using Moringa Olifeira for Water Treatment

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Background: Among all liquids, water is a unique substance and one of the most important natural resources. In the absence of safe and adequate drinking water supplies, diseases such as diarrhea, skin and eye infections are common. Treatment methods were thus required in order to protect the health of consumers. Currently seed of tropical plant Moringa Olifeira is being recommended as cost effective technology for water treatment in developing countries. The pH at which coagulation occurs is the most important parameter for proper coagulation performance as it affects the surface charge of colloids. Objective: The present study was carried out to determine effect of water pH on turbidity removal and bacterial load reduction using Moringa Olifeira for water treatment. Methods: During this study, ground water from open well and tap water were collected for treatment by Moringa Olifeira seeds in powdered form. Primarily the minimum dose of Moringa Olifeira for effective treatment was identified. Then coagulation ability of Moringa Olifeira seed extract was assessed at different pH values (4, 5, 6, 7, 8, and 9) of water. Parameters which may influence coagulation effectiveness of Moringa Olifeira were kept under control during experimental procedure. Result: The result showed that 60mg of Moringa Olifeira is the optimum dose to treat water with 167NTU initial turbidity and 310 total coliforms. The effect of water PH on total coliforms reduction and turbidity removal effectiveness of Moringa Olifeira was studied and its removal effectiveness is also found to be 90.32% and 90.34% respectively. The pH evaluated has statistically significant effects on the turbidity removal and total coliform reduction with the p-values much lower than 0.05(1.2*10-11). Conclusion: Effectiveness of Moringa Olifeira in reducing turbidity and bacterial load is significantly affected by water pH values. Therefore effect that could arise from variation in the pH of water should be considered. Sequentially, since Moringa Olifeira does not guarantee impurity removal as World Health Organization guidelines, additional disinfection of coagulated water to remove pathogens is necessary in order to achieve standard quality before the water is drunk

description: We calculate shear viscosity and bulk viscosity in SU(3) gauge theory on the lattice at $1.5 \,T_c$. The viscosities are extracted via a Kubo formula from the reconstructed spectral function which we determine from the Euclidean-time dependence of the corresponding channel of the energy-momentum tensor correlators. We obtain unprecedented precision for the correlators by applying gradient flow and blocking methods. The correlators are extrapolated to the continuum and then to zero flow time. To extract the viscosities we fit theoretically inspired models to the lattice data and crosscheck the fit results using the Backus Gilbert method. The final estimates for shear and bulk viscosity are $η/s = 0.15-0.48$ and $ζ/s = 0.017-0.059$.

description: This letter considers a two-receiver multiple-input multiple-output (MIMO) Gaussian broadcast channel model with integrated services. Specifically, we combine two sorts of service messages, and serve them simultaneously: one multicast message intended for both receivers and one confidential message intended for only one receiver. The confidential message is kept perfectly secure from the unauthorized receiver. Due to the coupling of service messages, it is intractable to seek capacity-achieving transmit covariance matrices. Accordingly, we propose a suboptimal precoding scheme based on the generalized singular value decomposition (GSVD). The GSVD produces several virtual orthogonal subchannels between the transmitter and the receivers. Subchannel allocation and power allocation between multicast message and confidential message are jointly optimized to maximize the secrecy rate in this letter, subject to the quality of multicast service (QoMS) constraints. Since this problem is inherently complex, a difference-of-concave (DC) algorithm, together with an exhaustive search, is exploited to handle the power allocation and subchannel allocation, respectively. Numerical results are presented to illustrate the efficacy of our proposed strategies.

description: Starting with an orthogonal polynomial sequence $\{p_n(s)\}_{n=0}^\infty$ that has a discrete spectrum, we design an energy spectrum formula, $E_k = f (s_k)$, where $|{s_k\}$ is the finite or infinite discrete spectrum of the polynomial. Using a recent approach for doing quantum mechanics based, not on potential functions but, on orthogonal energy polynomials, we give a local numerical realization of the potential function associated with the chosen energy spectrum. In this work, we select the three-parameter continuous dual Hahn polynomial as an example. Exact analytic expressions are given for the corresponding bound states energy spectrum, scattering states phase shift, and wavefunctions. However, the potential function is obtained only numerically for a given set of physical parameters.

description: This paper investigates the feasibility of mmWave frequencies for personal networks of wireless wearable devices in enclosed settings (e.g., commuter trains, subways, airplanes, airports, or offices). At these frequencies, specular reflections off surfaces are expected to contribute intended signal power and, simultaneously, to aggravate the interference at the receivers. Meanwhile, blockages by obstacles and people---including the individuals wearing the devices---are expected to shield receivers from interference. With the aid of stochastic geometry and random shape theory, we assess the interplay of surface reflections and blockages for dense deployments of wearable networks equipped with directional antenna arrays in relevant indoor settings.

Year: 2006

description: Background: Currently, HBC programs for PLWHA are implemented in different African countries after the inceptions of the epidemic. However, the designed HBC programs may differ from place to place, that means whether model of community/NGO-based initiative or Hospital-based initiative HBC programs. To implement CHBC program for PLWHA efficiently and effectively, it is necessary to assess the perceptions and contextual experience of home caregivers in the community. Objective: It was to assess and explore the contextual based experience of CVHBC service for PLWHA in oromia region, Adama (Nazareth) town. Methods: Using a qualitative method the perceptions, range of activities, and the major challenges in HBC were described in this study. In-depth interview and FGDs were conducted with VHC givers and their team leaders selected from the 'six' HBC-teams in the town. The selection of study-participants was purposive with the aim of obtaining knowledgeable and experienced individual VHC-givers from the team members. Findings: The findings were described in three categories: perception of VHC givers to HBC, range of HBC activities, and challenges in HBC. The result showed that VHC givers perceived that HBC is a continuum of care that help PLWHA by providing basic care according to their needs in their home without any gap between health facilities and HBC. However, they performed a limited range of home care activities that were inadequate care. Further more, patients' poverty, lack of adequate resources, lack of adequate support; presence of stigma, rejection, and abuse; lack of training and supervision by health professional and for caregivers, and lack of health care infrastructures were indicated as the major factors that affect the provision of better quality home care. v Conclusion: In general, the HBC process in the study areas were indicated that it was unorganized and not coordinated, which means there was lack of professional support as well as lack of adequate materials and financial support besides the lack of all stakeholders' participations, lack of adequate HBC infrastructure and the absence of communications among the organizations. Further studies, however, are recommended for better understanding of these major challenging issues in HBC of PLWHA, using a combination of qualitative & quantitative research methods

description: Weak lensing studies via cosmic voids are a promising probe of Modified Gravity (MG). Excess surface mass density (ESD) is widely used as a lensing statistic in weak lensing research. In this paper, we use the ray-tracing method to study the ESD around voids in simulations based on Cubic Galileon (CG) gravity. With the compilation of N-body simulation and ray-tracing method, changes in structure formation and deflection angle resulting from MG can both be considered, making the extraction of lensing signals more realistic. We find good agreements between the measurement and theoretical prediction of ESD for CG gravity. Meanwhile, the lensing signals are much less affected by the change of the deflection angle than the change of the structure formation, indicating a good approximation of regarding ESD (statistics) as the projection of 3D dark matter density field. Finally, we demonstrate that it is impossible to distinguish CG and General Relativity in our simulation, however, in the next-generation survey, thanks to the large survey area and the increased galaxy number density, detecting the differences between these two models is possible. The methodology employed in this paper that combines N-body simulation and ray-tracing method can be a robust way to measure the lensing signals from simulations based on the MGs, and especially on that which significantly modifies the deflection angle.

description: The increased relevance of liver surgery and transplantation as a therapeutic modality over the last two decades mandates the development of novel strategies to improve liver regeneration. Here we studied whether erythropoietin (EPO) improves liver regeneration after hepatectomy in pigs. Eighteen female pigs underwent laparoscopic left lateral liver resection and were allocated randomly into three groups. No EPO was administered to the control group (group 1, n=6). Group 2 (n=6) received EPO topically to the liver resection surface in a fibrin sealant. Group 3 (n=6) received EPO topically and systemically. Pigs were sacrificed 14 days after hepatectomy. The fraction of proliferating hepatocytes was determined by ki-67 immunostaining. Liver volume was determined by the principle of Archimedes, Liver weight and volume were significantly increased in group 3 (1249 ± 223 g, 1073 ± 190 ml) compared to group 2 (1027 ± 167 g, 894 ± 105 ml) and group 1 (923 ± 186 g, 813 ± 165 ml). Ki-67 immunostaining of liver tissue close to the resection surface demonstrated a significantly increased percentage of proliferating hepatocytes in group 3 (4.3 ± 1.96 %) and in group 2 (3.5% ± 0.98 %) as compared to group 1 (1.15 ± 1.2 %) 14 days after hepatectomy. Our results indicate for the first time that EPO supports liver regeneration after hepatectomy.

description: We propose a mechanism of producing a new type of primordial perturbations that collapse to primordial black holes whose mass can be as large as necessary for them to grow to the supermassive black holes observed at high redshifts, without contradicting COBE/FIRAS upper limits on cosmic microwave background (CMB) spectral distortions. In our model, the observable Universe consists of two kinds of many small patches which experienced different expansion histories during inflation. Primordial perturbations large enough to form primordial black holes are realized on patches that experienced more Hubble expansion than the others. By making these patches the minor component, the rarity of supermassive black holes can be explained. On the other hand, most regions of the Universe experienced the standard history and, hence, only have standard almost-scale-invariant adiabatic perturbations confirmed by observations of CMB or large-scale structures of the Universe. Thus, our mechanism can evade the constraint from the nondetection of the CMB distortion set by the COBE/FIRAS measurement. Our model predicts the existence of supermassive black holes even at redshifts much higher than those observed. Hence, our model can be tested by future observations peeking into the higher-redshift Universe.

description: Idiopathic scoliosis is a common cause of spinal deformity in children and adolescents. Although the incidence of the scoliosis is up to 2 %-3 % of the world’s population, the pathogenesis is still obscure. Recent evidences show that the disease has a hereditary basis. Clinical manifestations as well as family studies reveal the familial tendency of idiopathic scoliosis, and support that the heredity is an important cause of this disease. Many related genes, such as SNTGI and CHD7, are believed to play a role in the development of idiopathic scoliosis but the underlying mechanism is still not clear. This review focus on the mode of inheritance of idiopathic scoliosis and some related molecules.

Blast waves in the zero temperature hard sphere gas: double scaling structure

description: We study the blast generated by sudden localized release of energy in a cold gas. Specifically, we consider one-dimensional hard-rod gas and two-dimensional hard disc gas. For this problem, the Taylor-von Neumann-Sedov (TvNS) solution of Euler equations has a self-similar form. The shock wave remains infinitely strong for the zero-temperature gas, so the solution applies indefinitely. The TvNS solution ignores dissipation, however. We show that this is erroneous in the core region which, in two dimensions, expands as $t^{2/5}$ while the shock wave propagates as $t^{1/2}$. A new self-similar solution depending on the scaling variable $r/t^{2/5}$ describes the core, while the TvNS solution describes the bulk. We demonstrate this from a numerical solution of the Navier-Stokes (NS) equations and from molecular dynamics simulations for a gas of hard discs in two dimensions and hard rods in one dimension. In both cases, the shock front position predicted by NS equations and by the TvNS solution agrees with that predicted by molecular dynamics simulations. However, the NS equations fail to describe the near-core form of the scaling functions.
Optical beam shifts in graphene and single-layer boron-nitride

description: Optical beam shifts from a free-standing two-dimensional atomic crystal are investigated. In contrast to a three-dimensional crystal the magnitude of the Goos-H$\rm \ddot{a}$nchen shift depends on the surface susceptibility of the crystal and not on the wavelength of the incident light beam. The surface conductivity of the atomically thin crystal is less important in this context because it enters in the expression of the shifts only as a second order parameter. In analogy to a three-dimensional crystal the magnitudes of the Imbert-Fedorov shift and of the angular shifts depend respectively on the wavelength and on the square of the beam angular aperture.

description: Property graphs have reached a high level of maturity, witnessed by multiple robust graph database systems as well as the ongoing ISO standardization effort aiming at creating a new standard Graph Query Language (GQL). Yet, despite documented demand, schema support is limited both in existing systems and in the first version of the GQL Standard. It is anticipated that the second version of the GQL Standard will include a rich DDL. Aiming to inspire the development of GQL and enhance the capabilities of graph database systems, we propose PG-Schema, a simple yet powerful formalism for specifying property graph schemas. It features PG-Types with flexible type definitions supporting multi-inheritance, as well as expressive constraints based on the recently proposed PG-Keys formalism. We provide the formal syntax and semantics of PG-Schema, which meet principled design requirements grounded in contemporary property graph management scenarios, and offer a detailed comparison of its features with those of existing schema languages and graph database systems.

description: A monolayer of molecules or quantum dots sandwiched between electrodes can be driven out of equilibrium by the application of a bias voltage between the electrodes. We study charge ordering, i.e., the spontaneous formation of a charge density wave, and the perpendicular current in such a system within a master-equation approach augmented by mean-field and classical Monte Carlo methods. Our approach is suitable for weak tunneling between the monolayer and the electrodes. For a square lattice with nearest-neighbor Coulomb repulsion, we present a comprehensive study of the zero-temperature phases controlled by the on-site energy, the bias voltage, and the degeneracy of the occupied single-site state. One of the most interesting results is the prediction of a conducting charge-density-wave phase that only occurs at a finite bias voltage. We also study the universality classes of the phase transitions towards charge-ordered states at zero and nonzero temperatures. While all transitions at $T>0$ and some at $T=0$ belong to the two-dimensional Ising universality class, we also find an absorbing-to-active phase transition in the $\mathbb{Z}_2$ symmetric directed percolation (DP2) class at $T=0$.

description: We discuss the codimension-1 defects of (2+1)D bosonic topological phases, where the defects can support fermionic degrees of freedom. We refer to such defects as fermionic defects, and introduce a certain subclass of invertible fermionic defects called "gauged Gu-Wen SPT defects" that can shift self-statistics of anyons. We derive a canonical form of a general fermionic invertible defect, in terms of the fusion of a gauged Gu-Wen SPT defect and a bosonic invertible defect decoupled from fermions on the defect. We then derive the fusion rule of generic invertible fermionic defects. The gauged Gu-Wen SPT defects give rise to interesting logical gates of stabilizer codes in the presence of additional ancilla fermions. For example, we find a realization of the CZ logical gate on the (2+1)D $\mathbb{Z}_2$ toric code stacked with a (2+1)D ancilla trivial atomic insulator, which is implemented by a finite depth circuit. We also investigate a gapped fermionic interface between (2+1)D bosonic topological phases realized on the boundary of the (3+1)D Walker-Wang model. In that case, the gapped interface can shift the chiral central charge of the (2+1)D phase. Among these fermionic interfaces, we study an interesting example where the (3+1)D phase has a spatial reflection symmetry, and the fermionic interface is supported on a reflection plane that interpolates a (2+1)D surface topological order and its orientation-reversal. We construct a (3+1)D exactly solvable Hamiltonian realizing this setup, and find that the model generates the $\mathbb{Z}_8$ classification of the (3+1)D invertible phase with spatial reflection symmetry and fermion parity on the reflection plane. We make contact with an effective field theory, known in literature as the exotic invertible phase with spacetime higher-group symmetry.
