description: The Hamiltonian formulation for nonlinear chiral 2-form electrodynamics in six-dimensional Minkowski spacetime is used to show that small-amplitude plane-wave perturbations of a generic uniform constant `magnetic' background exhibit trirefringence: all three independent wave-polarisations have distinct dispersion relations. While two coincide for Lorentz invariant theories, all three coincide uniquely for the chiral 2-form theory on the worldvolume of the M5-brane of M-theory. We argue that this is because, in this M-theory context, the waves propagate in a planar M5-M2-M2 bound-state preserving 16 supersymmetries. We also show how our results imply analogous results for nonlinear electrodynamics in a Minkowski spacetime of five and four dimensions.

description: The rich physics program at the high luminosity LHC (HL-LHC) requires all final state particles to be reconstructed with good accuracy. However, it also poses formidable challenge of dealing with very high pileup. Different identification algorithms need to be upgraded along with the detectors to improve the overall event reconstruction in such a hostile collision environment. The new timing device in the proposed CMS detector at the HL-LHC allows for the construction of timing observables at the track-level as well as at the jet-level. This information when given as inputs to the deep neural networks, have a potential to improve the existing algorithms used for heavy flavor (HF) jet tagging. In this paper, the latest developments on the studies for HF jet tagging performance at the HL-LHC are presented.
What drives pregnant women to choose their food? A qualitative study in Butajira Rural Health Programme (BRHP), Ethiopia
Creators: name: Shiferaw, Seble

description: Background: The maternal nutrition during pregnancy is responsible for structural and physiological changes that occur in the fetus as a result of inadequate nutrients or 'building blocks' for the growth of specific tissues. The nutrient a mother gets depends on her food choices, signifying the importance food choice during pregnancy. Objective: To explore factors which influence food choice among pregnant women in Butajira Rural Health Programme (BRHP), Ethiopia. Method: Qualitative content analysis using deductive approach was applied to identify factors affecting food choice of pregnant women in rural settings. The study conducted in Health and Demographic Surveillance Site (HDSS) of Addis Ababa University School of Public Health located in Butajira, Gurage zone. A total of 43 pregnant women and 37 husbands of pregnant women participated in the study. A combination of in-depth interview and focus group discussion was applied to collect data from purposively selected participants. The data analyzed deductively, using open code version 4.02 software to code the data. Result: Pregnant women usually ate three times a day that mainly consisted of cereal based food (Kita) and a vegetable, dark green leafy vegetable (Gomen). The study identified several factors which influence pregnant women to choose their food. Agricultural production seems to be a key determinant of consumption and is dependent on the amount of agricultural land they have and agro-ecologic conditions among the study sites. It is also identified that the major determinant of food choice is financial constraint, which determine the ability to produce or purchase the required food. Pregnant women adjust their food choice based on their appetite and gastric symptoms following consumption. The distant market is another factor identified as an obstacle to access healthy food due to high cost of transportation and unstable roads for a pregnant woman. Conclusion: This study identified that the food choice of pregnant women is mainly determined by food availability which is governed by production and financial capacity. Pregnant women also decrease their food intake due to physiological symptoms following consumption.

description: We propose an aqueous functionalized molybdenum disulfide nanoribbon suspended over a solid electrode as the first capacitive displacement sensor aimed at determining the DNA sequence. The detectable sequencing events arise from the combination of Watson-Crick base-pairing, one of nature's most basic lock-and-key-binding mechanisms, with the ability of appropriately sized atomically thin membranes to flex substantially in response to sub-nanonewton forces. We employ carefully designed numerical simulations and theoretical estimates to demonstrate excellent (79 % to 86 %) raw target detection accuracy at ~70 million bases per second and electrical measurability of the detected events. In addition, we demonstrate reliable detection of repeated DNA motifs. Finally, we argue that the use of a nanoscale opening (nanopore) is not requisite for the operation of the proposed sensor and present a simplified sensor geometry without the nanopore as part of the sensing element. Our results therefore potentially suggest a realistic, inherently base-specific, high-throughput electronic DNA sequencing device as a cost-effective de-novo alternative to the existing methods.

description: We present a new parton distribution function analysis which includes new data for W boson production in proton-proton collisions and lepton pair production in proton-proton and proton-deuteron collisions. The new data provide strong constraints on the light antiquark parton distribution functions in the proton. We identify an interesting correlation between the $d/u$ ratio and the $\bar{d}/\bar{u}$ ratio which leads to a modification of our previous results for the $d/u$ ratio as the parton momentum fraction $x \rightarrow 1.$

description: Greek and foreign philosophers and scientists have shown a particular interest in the natural world over time and have tried to understand and answer any question that has troubled them. One of these issues, was the study and interpretation, of the motion of bodies and any possible changes associated with it. To this end, they proposed various theories, concerning the study of the motion of a body, the most important being that of Aristotle, as it influenced the reasoning of the generations that followed, until the time of Galileo, who introduced a new theory, which was developed by later scientists. Firstly, the present thesis aims to investigate the views of philosophers and scientists regarding motion and the emergence through them, the principle of inertia, and examine the alternative perceptions of students on this subject. Finally, the paper also aims to present a teaching proposal for teaching the principle of inertia in middle school

description: We present the discovery of the X-ray and optical afterglows of the short-duration GRB 150101B, pinpointing the event to an early-type host galaxy at z=0.1343 +/- 0.0030. This makes GRB 150101B the most nearby short GRB with an early-type host galaxy discovered to date. Fitting the spectral energy distribution of the host galaxy results in an inferred stellar mass of ~7x10^10 M_sol, stellar population age of ~2-2.5 Gyr, and star formation rate of <0.4 M_sol yr^-1. The host of GRB 150101B is one of the largest and most luminous short GRB host galaxies, with a B-band luminosity of ~4.3L* and half-light radius of ~8 kpc. GRB 150101B is located at a projected distance of 7.35 +/- 0.07 kpc from its host center, and lies on a faint region of its host rest-frame optical light. Its location, combined with the lack of associated supernova, is consistent with a NS-NS/NS-BH merger progenitor. From modeling the evolution of the broad-band afterglow, we calculate isotropic-equivalent gamma-ray and kinetic energies of ~1.3x10^49 erg and ~(6-14)x10^51 erg, respectively, a circumburst density of ~(0.8-4)x10^-5 cm^-3, and a jet opening angle of >9 deg. Using observations extending to ~30 days, we place upper limits of

description: In conventional plasmonic media and plasmonic metamaterials, such as metallic wire mesh, longitudinal mode of electromagnetic wave manifests itself in frequency overlapping transverse modes, which impedes clear observation of longitudinal-mode-specific physical effects. Through interlacing two sets of wire meshes, an ideal band for longitudinal mode is achieved ranging from zero frequency to plasma frequency where transverse modes are completely forbidden. The unique spectral separation of modes facilitates the observation of pure longitudinal mode and related plasmonic effects in bulk medium. We report the first experiment of anomalous optical transmission, induced solely by electromagnetic longitudinal mode resonance, below plasma frequency in the wire mesh medium.

description: We derive exact analytical formulas for the radiative heat transfer between parallel slabs separated by vacuum and subject to arbitrary temperature profiles. We show that, depending on the derivatives of the temperature at points close to the slab--vacuum interfaces, the flux can exhibit one of several different asymptotic low-distance ($d$) behaviors, obeying either $1/d^2$, $1/d$, or logarithmic power laws, or approaching a constant. Tailoring the temperature profile within the slabs could enable unprecedented tunability over heat exchange, leading for instance to sign-flip transitions (where the flux reverses sign) at tunable distances. Our results are relevant to the theoretical description of on-going experiments exploring near-field heat transfer at nanometric distances, where the coupling between radiative and conductive heat transfer could be at the origin of temperature gradients.

description: This Letter presents a search for new resonances with mass larger than 250 GeV, decaying to a $Z$ boson and a photon. The dataset consists of an integrated luminosity of 3.2 fb$^{-1}$ of $pp$ collisions collected at $\sqrt{s} = 13$ TeV with the ATLAS detector at the Large Hadron Collider. The $Z$ bosons are identified through their decays either to charged, light, lepton pairs ($e^+e^-$, $μ^+μ^-$) or to hadrons. The data are found to be consistent with the expected background in the whole mass range investigated and upper limits are set on the production cross section times decay branching ratio to $Zγ$ of a narrow scalar boson with mass between 250 GeV and 2.75 TeV.

description: In this paper, we describe a compact and practical algorithm to construct Hermitian Young projection operators for irreducible representations of the special unitary group SU(N), and discuss why ordinary Young projection operators are unsuitable for physics applications. The proof of this construction algorithm uses the iterative method described by Keppeler and Sjödahl. We further show that Hermitian Young projection operators share desirable properties with Young tableaux, namely a nested hierarchy when "adding a particle". We end by exhibiting the enormous advantage of the Hermitian Young projection operators constructed in this paper over those given by Keppeler and Sjödahl.

description: In optically controlled quantum computers it may be favorable to address different qubits using light with different frequencies, since the optical diffraction does not then limit the distance between qubits. Using qubits that are close to each other enables qubit-qubit interactions and gate operations that are strong and fast in comparison to qubit-environment interactions and decoherence rates. However, as qubits are addressed in frequency space, great care has to be taken when designing the laser pulses, so that they perform the desired operation on one qubit, without affecting other qubits. Complex hyperbolic secant pulses have theoretically been shown to be excellent for such frequency-addressed quantum computing [I. Roos and K. Molmer, Phys. Rev. A 69, 022321 (2004)]—e.g., for use in quantum computers based on optical interactions in rare-earth-metal-ion-doped crystals. The optical transition lines of the rare-earth-metal-ions are inhomogeneously broadened and therefore the frequency of the excitation pulses can be used to selectively address qubit ions that are spatially separated by a distance much less than a wavelength. Here, frequency-selective transfer of qubit ions between qubit states using complex hyperbolic secant pulses is experimentally demonstrated. Transfer efficiencies better than 90% were obtained. Using the complex hyperbolic secant pulses it was also possible to create two groups of ions, absorbing at specific frequencies, where 85% of the ions at one of the frequencies was shifted out of resonance with the field when ions in the other frequency group were excited. This procedure of selecting interacting ions, called qubit distillation, was carried out in preparation for two-qubit gate operations in the rare-earth-metal-ion-doped crystals. The techniques for frequency-selective state-to-state transfer developed here may be also useful also for other quantum optics and quantum information experiments in these long-coherence-time solid-state systems.

description: We have designed a passive spintronic diode based on a single skyrmion stabilized in a magnetic tunnel junction and studied its dynamics induced by voltage-controlled anisotropy (VCMA) and Dzyaloshinskii-Moriya interaction (VDMI). We have demonstrated that the sensitivity (rectified voltage over input microwave power) with realistic physical parameters and geometry can be larger than 10 kV/W which is one order of magnitude better than diodes employing a uniform ferromagnetic state. Our numerical and analytical results on the VCMA and VDMI-driven resonant excitation of skyrmions beyond the linear regime reveal a frequency dependence on the amplitude and no efficient parametric resonance. Skyrmions with a smaller radius produced higher sensitivities, demonstrating the efficient scalability of skyrmion-based spintronic diodes. These results pave the way for designing passive ultra-sensitive and energy efficient skyrmion-based microwave detectors.

description: Background: Despite persistent HIVand syphilis epidemics among men who have sex with men (MSM), the relationship between HIVand syphilis contact networks has not been well characterized.We aimed to measure interconnectivity between HIV and syphilis contact networks among MSM and identify network communities with heightened interconnectivity of the syphilis network with the HIV network. Methods: Using contact-tracing data, we generated independent and combined HIV and syphilis networks for all MSM diagnosed with HIVor early syphilis, respectively, in North Carolina between 2015 and 2017. We treated the independent networks as layers and identified network communities, or groups of densely connected nodes, in the 2-layer network. We assessed interconnectivity by comparing the mean node degree among syphilis network members in the syphilis network alone versus the combined HIV/syphilis network, both overall and by network community. Results: The syphilis network was interconnected with the HIV network, especially in network communities with younger median age, higher proportions of persons self-identifying as Black, non-Hispanic, and higher proportions of syphilis cases diagnosed at sexually transmitted disease clinics. Conclusions: Interconnected contact networks underlie HIVand syphilis epidemics among MSM, particularly among young, Black MSM. Intensified transmission prevention interventions within highly interconnected network communities may be particularly beneficial.

description: The polarized dust emission observed in Class 0 protostellar cores at high angular resolution with ALMA has raised several concerns about the grain alignment conditions in these regions. We aim to study the role of the radiation field on the grain alignment mechanisms occurring in the interior (<1000 au) of Class 0 protostars. We produce synthetic observations of the polarized dust emission from a MHD model of protostellar formation, using the POLARIS dust radiative transfer tool, which includes dust alignment with Radiative Torques Alignment (RATs). We test how the polarized dust emission from the model core depends on the irradiation conditions in the protostellar envelope, by varying the radiation due to accretion luminosity propagating from the central protostellar embryo throughout the envelope. The level of grain alignment efficiency obtained in the radiative transfer models is then compared to (sub-) millimeter ALMA dust polarization observations of Class 0 protostars. Our radiative transfer calculations have a central irradiation that reproduces the protostellar luminosities typically observed towards low- to intermediate-mass protostars, as well as super-paramagnetic grains, and grains >10 micron, which are required to bring the dust grain alignment efficiencies of the synthetic observations up to observed levels. Our radiative transfer calculations show that irradiation plays an important role in the mechanisms that dictate the size range of aligned grains in Class 0 protostars. Regions of the envelope that are preferentially irradiated harbor strong polarized dust emission but can be affected by the rotational disruption of dust grains. Episodes of high luminosity could affect grain alignment and trigger grain disruption mechanisms. [abridged]

description: Classical objectives in two-player zero-sum games played on graphs often deal with limit behaviors of infinite plays: e.g., mean-payoff and total-payoff in the quantitative setting, or parity in the qualitative one (a canonical way to encode omega-regular properties). Those objectives offer powerful abstraction mechanisms and often yield nice properties such as memoryless determinacy. However, their very nature provides no guarantee on time bounds within which something good can be witnessed. In this work, we consider two approaches toward inclusion of time bounds in parity games. The first one, parity-response games, is based on the notion of finitary parity games [CHH09] and parity games with costs [FZ14,WZ16]. The second one, window parity games, is inspired by window mean-payoff games [CDRR15]. We compare the two approaches and show that while they prove to be equivalent in some contexts, window parity games offer a more tractable alternative when the time bound is given as a parameter (P-c. vs. PSPACE-c.). In particular, it provides a conservative approximation of parity games computable in polynomial time. Furthermore, we extend both approaches to the multi-dimension setting.

description: We consider low-scale leptogenesis via right-handed neutrinos $N$ coupled to a $Z'$ boson, with gauged $U(1)_{B-L}$ as a simple realization. Keeping the neutrinos sufficiently out of equilibrium puts strong bounds on the $Z'$ coupling strength and mass, our focus being on light $Z'$ and $N$, testable in the near future by SHiP, HPS, Belle II, and at the LHC. We show that leptogenesis could be robustly falsified in a large region of parameter space by the double observation of $Z'$ and $N$, e.g. in the channel $pp\to Z' \to NN$ with displaced $N$-decay vertex, and by several experiments searching for light $Z'$, according to the mass of $N$.

sustainability assessment

description: In CIRCULAR FoodPack project, the newly developed value chains as part of WP2 and WP3 are assessed by means of a holistic life cycle sustainability assessment (LCSA), taking into account environmental impacts through Life Cycle Assessment (LCA), economic impacts through Life Cycle Costing (LCC) and social impacts through Social LCA (S-LCA).

Within the life cycle thinking approach, four phases are relevant to obtain the assessments:

a)  the goal and scope definition phase,b)  the inventory analysis phase,c)  the impact assessment phase andd)  the interpretation phase (ISO 14044, 2006).

From June 2021 to November 2022, the emphasis was placed on the first two phases. This comprises the definition of the different scenarios which are based on the three use cases that are home packaging (H), personal care packaging (PC) and food packaging (F) including the following six demonstrators/applications: Wet wipes (H1), Detergent tabs (H2), Cosmetics in sachets (PC1), Chocolate powder (F1), Coffee (F2) and Creamer (F3). Regarding the applications, three main loops (loop 1-3) are considered differing for instance in the input of either mixed food-flexibles and non-food flexibles or solely food-flexibles. Another important step was the creation of process flow schemes in close cooperation with the project partners for the following processes:

Collection, SoA sorting and Tracer-based sorting,

Pretreatment including Oversorting, Shredding, Washing, Grinding and Float-sink separation,

Purification with option A-CreaSolv®® and option B-Deinking and Delamination,

Posttreatment consisting of Recompounding and Deodorization,

Laminate production and also considering Ink production, Primer production and Tracer production and

Food packaging production.

Based on this work, data collection for LCA and LCC inventories is completed by the respective partners to obtain the data for the preliminary sustainability assessment. The collection of S-LCA data is not considered in this deliverable as the impact indicators relevant for the system will be selected in a next step.

description: We present an analysis of high-quality photometry for globular clusters (GCs) in the Virgo cluster core region, based on data from the Next Generation Virgo Cluster Survey (NGVS) pilot field, and in the Milky Way (MW) based on VLT/X-Shooter spectrophotometry. We find significant discrepancies in color-color diagrams between sub-samples from different environments, confirming that the environment has a strong influence on the integrated colors of GCs. GC color distributions along a single color are not sufficient to capture the differences we observe in color-color space. While the average photometric colors become bluer with increasing radial distance to the cD galaxy M87, we also find a relation between the environment and the slope and intercept of the color-color relations. A denser environment seems to produce a larger dynamic range in certain color indices. We argue that these results are not due solely to differential extinction, IMF variations, calibration uncertainties, or overall age/metallicity variations. We therefore suggest that the relation between the environment and GC colors is, at least in part, due to chemical abundance variations, which affect stellar spectra and stellar evolution tracks. Our results demonstrate that stellar population diagnostics derived from model predictions which are calibrated on one particular sample of GCs may not be appropriate for all extragalactic GCs. These results advocate a more complex model of the assembly history of GC systems in massive galaxies that goes beyond the simple bimodality found in previous decades.

description: Stimulated-echo spectroscopy has recently been applied to study the ultra-slow dynamics of nuclear spin-3/2 probes such as 7^Li and 9^Be in solids. Apart from the dominant first-order quadrupolar interaction in the present article also the impact of the homonuclear dipolar interactions is considered in a simple way: the time evolution of a dipole coupled pair of spins with I=3/2 is calculated in an approximation, which takes into account that the satellite transitions usually do not overlap. Explicit analytical expressions describing various aspects of a coupled quadrupolar pair subjected to a Jeener–Broekaert pulse sequence are derived. Extensions to larger spin systems are also briefly discussed. These results are compared with experimental data on a single-crystalline Li ion conductor.
The formation of globular clusters with top-heavy initial mass functions

description: We study the formation of globular clusters in massive compact clouds with the low-metallicity of $Z=10^{-3}~Z_{\odot}$ by performing three-dimensional radiative-hydrodynamics simulations. Considering the uncertainty of the initial mass function (IMF) of stars formed in low-metallicity and high-density clouds, we investigate the impacts of the IMF on the cloud condition for the GC formation with the range of the power-law index of IMF as $γ= 1-2.35$. We find that the threshold surface density ($Σ_{\rm thr}$) for the GC formation increases from $800~M_{\odot} \; {\rm pc^{-2}}$ at $γ= 2.35$ to $1600~M_{\odot}\; {\rm pc^{-2}}$ at $γ= 1.5$ in the cases of clouds with $M_{\rm cl} = 10^6~M_{\odot}$ because the emissivity of ionizing photons per stellar mass increases as $γ$ decreases. For $γ< 1.5$, $Σ_{\rm thr}$ saturates with $\sim 2000~M_{\odot}\; {\rm pc^{-2}}$ that is quite rare and observed only in local starburst galaxies due to e.g., merger processes. Thus, we suggest that formation sites of low-metallicity GCs could be limited only in the very high-surface density regions. We also find that $Σ_{\rm thr}$ can be modelled by a power-law function with the cloud mass ($M_{\rm cl}$) and the emissivity of ionizing photons ($s_*$) as $\propto M_{\rm cl}^{-1/5} s_{*}^{2/5}$. Based on the relation between the power-law slope of IMF and $Σ_{\rm thr}$, future observations with e.g., the James Webb Space Telescope can allow us to constrain the IMF of GCs.

Determinants of use of skilled birth attendance among mothers who gave birth in the past 12 months in Raya Alamata District: community based Comparative cross sectional study
Creators: name: Tadese, Fentaw
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2013

description: Background: A large number of women are dying due to factors related to pregnancy and childbirth, especially in developing countries including Ethiopia, where maternal mortality ratio is one of the highest in the world. It is known that having a skilled birth attendant at every delivery can lead to marked reductions in maternal mortality. In Ethiopia, most births take place at home, particularly in rural areas, being not attended by a skilled birth attendant. The utilization of maternal health services is a complex phenomenon and it is influenced by several factors. Objectives: This study assessed factors that determine the utilization of skilled birth attendants among mothers who gave birth in the past 12 months in Raya Alamata District, Tigray Region, Ethiopia. Methods: Community-based comparative cross sectional study was conducted among mothers who gave birth in the past 12 months. Mixed methods of study combining both quantitative and qualitative research were used. A total of 580 study participants were recruited for the study. The investigator prepared pre-tested and structured questionnaire to collect data. Logistic regression was performed using SPSS version 16.0 software and thematic interpretation based on main categories was done for the qualitative data. Results: A total of 567 mothers (172 urban and 395 rural) were included in the analysis. Only 23.1% of births were attended by SBAs. Over 44% of urban women delivered with skilled assistance compared to 13.9% of rural women. In multivariate analysis urban residence (AOR = 2.2, 95%CI: 1.2, 4.0), maternal formal education (AOR=5.2, 95%CI: 3.0-8.8), ANC visit during the last pregnancy (AOR = 3.8, 95%CI: 2.0-7.3), joint final decision making (AOR=3.3, 95%CI: 1.9-6.1), knowledgeable (AOR=2.95, 95%CI: 1.7-5.1) and favourable attitude towards danger signs of pregnancy, child birth and delivery services (AOR=2.6, 95%CI: 1.3-5.1) were most significant determinants of SBA use by mother. Age at interview 15-24 and 25-34 had also a significant effect on skilled birth attendant utilization with (AOR=4.8, 95%CI: 2.0-11.6) and (AOR=3.8, (95%CI: 1.7-8.6) respectively. Conclusion and recommendation: Utilization of skilled delivery attendance services was still low with a high number of deliveries being attended by unqualified persons at home. Promotion of universal ANC follow-up and encouragement of mothers regarding the need for SBAs during childbirth is of paramount importance. Increase the awareness of mothers and their partners about the benefits of institutional delivery and SBAs and use of different means of behavioral change communication is very fundamental.

description: In this paper, we give a generic algorithm of the transition operators between Hermitian Young projection operators corresponding to equivalent irreducible representations of SU(N), using the compact expressions of Hermitian Young projection operators derived in a companion paper. We show that the Hermitian Young projection operators together with their transition operators constitute a fully orthogonal basis for the algebra of invariants of $V^{\otimes m}$ that exhibits a systematically simplified multiplication table. We discuss the full algebra of invariants over $V^{\otimes 3}$ and $V^{\otimes 4}$ as explicit examples. In our presentation we make use of various standard concepts such as Young projection operators, Clebsch-Gordan operators, and invariants (in birdtrack notation). We tie these perspectives together and use them to shed light on each other.

Παρά την ευρεία χρήση των κρυπτονομισμάτων σε όλο τον κόσμο για διάφορα ήδη αγορών και συναλλαγών, δεν υπάρχει ενοποιημένη θέση σχετικά με τον ορισμό των κρυπτονομισμάτων, καθώς και το νομικό τους πλαίσιο. Αυτό δημιουργεί δυσκολίες κατά τη διάρκεια εγκληματολογικών ερευνών για το ξέπλυμα χρήματος υπό τη χρήση κρυπτονομισμάτων. Συνεπώς, οι υπηρεσίες επιβολής του νόμου αντιμετωπίζουν προκλήσεις τόσο με την αναγνώριση της ταυτότητας των εγκληματιών όσο και με την τέλεση του αδικήματος. Η παρούσα εργασία μελετά τα προβλήματα ρύθμισης και νομοθέτησης, το νομικό πλαίσιο ανά χώρα, τις ρυθμιστικές αρχές, γνωστές μεθόδους και παραδείγματα ξεπλύματος χρήματος με κρυπτονομίσματα, καθώς και τα μέτρα καταπολέμησής του
description: The aim of our work is to examine the role of cryptocurrencies in the money laundering process. Despite the widespread use of cryptocurrencies around the world for various markets and transactions, there is no clear definition of cryptocurrencies and their legal framework. This creates difficulties during forensic investigations into money laundering using cryptocurrencies. As a result, law enforcement agencies face challenges in both identifying criminals and investigating crimes. This paper examines the problems of regulation and legislation, the legal framework by country, regulatory authorities, methods and cases of money laundering with cryptocurrencies as well as the measures to fight it
