description: Η παρούσα διπλωματική εργασία φιλοδοξεί να παρουσιάσει τις ιδιαίτερες πτυχές του εκτοπισμού του ελληνικού πληθυσμού των Σερρών κατά τη διάρκεια της βουλγαρικής κατοχής του 1916-1918. Αρχικά, παρουσιάζεται το ιστορικό πλαίσιο που οδήγησε στην κατοχή της Ανατολικής Μακεδονίας. Στη συνέχεια εξετάζονται οι λόγοι εκτοπισμού, οι διαδρομές και οι προορισμοί που ακολούθησαν οι εκτοπισμένοι, τόσο στο εσωτερικό της Ανατολικής Μακεδονίας όσο και στη Βουλγαρία, τη Σερβία και την Αλβανία. Επίσης, αναδεικνύονται οι συνθήκες διαβίωσής τους στην εξορία, ζητήματα όπως η διατροφή, οι υποδομές, η καταναγκαστική εργασία, η υγεία και γενικότερα η περίθαλψη και η επικοινωνία με την πατρίδα. Τέλος, γίνεται αναφορά στην παλιννόστηση των Ελλήνων και στις συνθήκες κάτω από τις οποίες αυτή έγινε. Ένα δεύτερο στοιχείο στο οποίο επικεντρώνεται η εργασία είναι η διερεύνηση της μνήμης του εκτοπισμού στην τοπική κοινωνία της περιοχής των Σερρών. Ειδικότερα, η έρευνα εστιάζει στα μνημεία που είναι αφιερωμένα στο γεγονός, στις μνήμες των θυμάτων που έχουν μείνει ζωντανές στις οικογένειες των απογόνων τους καθώς και στις προσπάθειες που καταβάλλονται από κάποιους απογόνους για την ανάδειξη της μνήμης στην τοπική και ευρύτερη κοινωνία.
description: The present diplomatic work aspires to present the particular aspects of the displacement of the Greek population of Serres during the Bulgarian occupation of 1916-1918. First, the historical context that led to the occupation of Eastern Macedonia is presented. The reasons for displacement, the routes and the destinations followed by the displaced, both within Eastern Macedonia and in Bulgaria, Serbia and Albania, are then examined. Also, their living conditions in exile, issues such as nutrition, infrastructure, forced labor, health and, in general, care and communication with the homeland, are highlighted. Finally, reference is made to the restoration of the Greeks and the conditions under which it took place. A second element on which the work focuses is the investigation of the memory of displacement in the local community of the Serres area. In particular, the research focuses on the monuments dedicated to the event, on the memories of the victims that have remained alive in the families of their descendants as well as on the efforts made by some descendants to highlight the memory in the local and wider society.

description: In a general spacetime, the possible choices for the field of orthonormal tetrads lead (in standard conditions) to equivalent Dirac equations. However, the Hamiltonian operator is got from rewriting the Dirac equation in a form adapted to a particular reference frame, or class of coordinate systems. That rewriting does not commute with changing the tetrad field $(u_α)$. The data of a reference frame F fixes a four-velocity field $v$, and also fixes a rotation-rate field $\MatΩ$. It is natural to impose that $u_0=v$. We show that then the spatial triad $(u_p)$ can only be rotating w.r.t. F, and that the title problem is solved if one imposes that the corresponding rotation rate $\MatΞ$ be equal to $\MatΩ$ - or also, if one imposes that $\MatΞ=\Mat{0}$. We also analyze other proposals which aimed at solving the title problem.

description: Magnetic Compton profiles (MCPs) of Ni and Fe along [111] direction have been calculated using a combined Density Functional and many-body theory approach. At the level of the local spin density approximation the theoretical MCPs does not describe correctly the experimental results around the zero momentum transfer. In this work we demonstrate that inclusion of electronic correlations as captured by Dynamical Mean Field Theory (DMFT) improves significantly the agreement between the theoretical and the experimental MCPs. In particular, an energy decomposition of Ni MCPs gives indication of spin polarization and intrinsic nature of Ni 6 eV satellite, a genuine many-body feature.

description: Scanning near-field optical microscopy is one of the most effective techniques for spectroscopy of nanoscale systems. However, inferring optical constants from the measured near-field signal can be challenging because of a complicated and highly nonlinear interaction between the scanned probe and the sample. Conventional fitting methods applied to this problem often suffer from the lack of convergence or require human intervention. Here we develop an alternative approach where the optical parameter extraction is automated by a deep learning network. Compared to its traditional counterparts, our method demonstrates superior accuracy, stability against noise, and computational speed when applied to simulated near-field spectra.

description: We present a new machine learning based bed-occupancy detection system that uses the accelerometer signal captured by a bed-attached consumer smartphone. Automatic bed-occupancy detection is necessary for automatic long-term cough monitoring, since the time which the monitored patient occupies the bed is required to accurately calculate a cough rate. Accelerometer measurements are more cost effective and less intrusive than alternatives such as video monitoring or pressure sensors. A 249-hour dataset of manually-labelled acceleration signals gathered from seven patients undergoing treatment for tuberculosis (TB) was compiled for experimentation. These signals are characterised by brief activity bursts interspersed with long periods of little or no activity, even when the bed is occupied. To process them effectively, we propose an architecture consisting of three interconnected components. An occupancy-change detector locates instances at which bed occupancy is likely to have changed, an occupancy-interval detector classifies periods between detected occupancy changes and an occupancy-state detector corrects falsely-identified occupancy changes. Using long short-term memory (LSTM) networks, this architecture was demonstrated to achieve an AUC of 0.94. When integrated into a complete cough monitoring system, the daily cough rate of a patient undergoing TB treatment was determined over a period of 14 days. As the colony forming unit (CFU) counts decreased and the time to positivity (TPP) increased, the measured cough rate decreased, indicating effective TB treatment. This provides a first indication that automatic cough monitoring based on bed-mounted accelerometer measurements may present a non-invasive, non-intrusive and cost-effective means of monitoring long-term recovery of TB patients.
(Un)mask yourself! Effects of face masks on facial mimicry and emotion perception during the COVID-19 pandemic

description: Face masks have been said to impact face-to-face interaction negatively. Yet, there is limited evidence on the degree to which partial face occlusion is detrimental to empathic processes such as emotion perception and facial mimicry. To address this question, we conducted an online experiment (N=200, U.K. sample) that assessed subjective ratings and facial expressions (mimicry) in response to masked and unmasked faces. Perceivers were able to recognise happiness and sadness in dynamic emotion expressions independent of (surgical) face masks. However, perceived emotion intensity and interpersonal closeness were reduced for masked faces. Facial mimicry, the perceiver’s imitation of the expresser’s emotional display, was reduced or absent in response to happy but preserved for sad mask-covered expressions. For happy target expressions, the face-mimicry link was partially mediated by perceived emotion intensity, supporting the idea that mimicry is influenced by context effects. Thus, these findings suggest that whether face masks impede emotion communication depends on the emotion expressed and the emotion-communication aspect of interest. With unprecedented changes in nonverbal communication brought about by the COVID-19 pandemic, this research marks a first contribution to our understanding of facial mimicry as an important social regulator during these times.

Combining spatial hints with policy reuse in a reinforcement learning agent
Creators: name: Da Silva, Bruno Norberto
Publisher: name: University of British Columbia
Year: 2010

description: In this dissertation, we study the problem of knowledge reuse by a reinforcement learning agent. We are interested in how an agent can exploit policies that were learned in the past to learn a new task more efficiently in the present. Our approach is to elicit spatial hints from an expert suggesting the world states in which each existing policy should be more relevant to the new task. By using these hints with domain exploration, the agent is able to detect those portions of existing policies that are beneficial to the new task, therefore learning a new policy more efficiently. We call our approach Spatial Hints Policy Reuse (SHPR). Experiments demonstrate the effectiveness and robustness of our method. Our results encourage further study investigating how much more efficacy can be gained from the elicitation of very simple advice from humans.

description: Qubits encoded in a decoherence-free subsystem and realized in exchange-coupled silicon quantum dots are promising candidates for fault-tolerant quantum computing. Benefits of this approach include excellent coherence, low control crosstalk, and configurable insensitivity to certain error sources. Key difficulties are that encoded entangling gates require a large number of control pulses and high-yielding quantum dot arrays. Here we show a device made using the single-layer etch-defined gate electrode architecture that achieves both the required functional yield needed for full control and the coherence necessary for thousands of calibrated exchange pulses to be applied. We measure an average two-qubit Clifford fidelity of $97.1 \pm 0.2\%$ with randomized benchmarking. We also use interleaved randomized benchmarking to demonstrate the controlled-NOT gate with $96.3 \pm 0.7\%$ fidelity, SWAP with $99.3 \pm 0.5\%$ fidelity, and a specialized entangling gate that limits spreading of leakage with $93.8 \pm 0.7\%$ fidelity.

description: The LHC has strongly constrained models of supersymmetry with traditional missing energy signatures. We present a variety of models that realize the concept of Stealth Supersymmetry, i.e. models with R-parity in which one or more nearly-supersymmetric particles (a "stealth sector") lead to collider signatures with only a small amount of missing energy. The simplest realization involves low-scale supersymmetry breaking, with an R-odd particle decaying to its superpartner and a soft gravitino. We clarify the stealth mechanism and its differences from compressed supersymmetry and explain the requirements for stealth models with high-scale supersymmetry breaking, in which the soft invisible particle is not a gravitino. We also discuss new and distinctive classes of stealth models that couple through a baryon portal or Z' gauge interactions. Finally, we present updated limits on stealth supersymmetry in light of current LHC searches.

description: The article sets out a number of considerations on the distinction between variability and uncertainty over the centuries. Games of chance have always been useful random experiments which through combinatorial calculation have opened the way to probability theory and to the interpretation of modern science through statistical laws. The article also looks briefly at the stormy nineteenth-century debate concerning the definitions of probability which went over the same grounds – sometimes without any historical awareness – as the debate which arose at the very beginnings of probability theory, when the great probability theorists were open to every possible meaning of the term.

description: In this article, we present numerical enhancements of a multiscale domain decomposition strategy based on a LaTIn solver and dedicated to the computation of the debounding in laminates. We show that the classical scale separation is irrelevant in the process zones, which results in a drop in the convergence rate of the strategy. The scalability is restored by performing nonlinear subresolutions in the vincinity of the front of the crack, at each prediction stage of the iterative solver.

description: In a Josephson junction, which is the central element in superconducting quantum technology, irreversibility arises from abrupt slips of the gauge-invariant quantum phase difference across the contact. A quantum phase slip (QPS) is often visualized as the tunneling of a flux quantum in the transverse direction to the superconducting weak link, which produces dissipation. In this work, we detect the instantaneous heat release caused by a QPS in a Josephson junction using time-resolved electron thermometry on a nanocalorimeter, signaled by an abrupt increase of the local electronic temperature in the weak link and subsequent relaxation back to equilibrium. Beyond providing a cornerstone in experimental quantum thermodynamics in form of observation of heat in an elementary quantum process, this result sets the ground for experimentally addressing the ubiquity of dissipation, including that in superconducting quantum sensors and qubits.

description: We revisit the four-point function of super gluons in $AdS_5 \times S^3$ in the spirit of the large $p$ formalism and show how the integrand of a generalised Mellin transform satisfies various non-trivial properties such as $U(1)$ decoupling identity, BCJ relations and colour-kinematic duality, in a way that directly mirrors the analogous relations in flat space. We unmix the spectrum of double-trace operators at large $N$ and find all anomalous dimensions at leading order. The anomalous dimensions follow a very simple pattern, resembling those of other theories with hidden conformal symmetries.

description: Single particle states in a chain with quasiperiodic potential show a metal-insulator transition upon the change of the potential strength. We consider two particles with local interaction in the single particle insulating regime. The two particle states change from being localized to delocalized upon an increase of the interaction strength to a nonperturbative finite value. At even larger interaction strength the states become localized again. This transition of two particle bound states into a correlated metal is due to a resonant mixing of the noninteracting two particle eigenstates. In the discovered correlated metal states two particles move coherently together through the whole chain, therefore contributing to a finite conductivity.

Reel Artists: National Film Board of Canada portrayals of contemporary Aboriginal and Inuit artists and their art
Creators: name: Robertson, Carmen Lee
Publisher: name: Education
Year: 2005

description: Bibliography: p. 214-241
description: The National Film Board of Canada (NFB) promotes itself as an educative force in Canada. The NFB's mandate to bring Canada to Canadians motivated a 'teaching' agenda inherent in its films. Beginning in the 1950s, the NFB began to produce films about contemporary Aboriginal artists. In so doing, it provided Canadians with one of the few sources for information about Canadian Aboriginal art until the 1980s when a number of publications and exhibitions began to emerge. The NFB films were meant to 'instruct' ordinary Canadians about Indigenous peoples and their culture. This dissertation investigates how the NFB constructed representations of Aboriginal art and artists by visually unpacking documentary films created between 1955 and 1988. By interpreting the visual language in the films, this interdisciplinary study analyzes how the NFB framed contemporary Aboriginal art and presented it to viewers. Theoretical and pragmatic applications of post-structural semiotics support the discussion of the representations. The medium of documentary film, with its supposed associations to realism, truth claims, and didactic lessons, complicate the analysis further. This study considers the underlying, but ever- present issues of colonialist power and here the work of Foucault provides guidance. A Canadian cultural imagination has contextualized noted NFB representations of Indigenous artists and their art. Yet, while the discourse of Aboriginal representations in art and literature enjoys greater scholarly attention today, little consideration has been given to how NFB productions contributed to this matter. Finally, this study includes a discussion of the implications of the analysis, including the significance of critically assessing how the NFB has represented Aboriginals to other Canadians through this series of documentary films. Because of the authoritative and educative voice of the NFB, as well as the stereotypical constructions found in the noted NFB films regarding Indigenous artists and their art, Canadian understandings of Indigenous artistic achievements remain skewed and heavily influenced by these films. Discussions surrounding contemporary Indigenous artists popularized in the NFB documentaries continue to reference the compromising racist framings embedded in the films. Furthermore, educators continue to unquestioningly trust these documentaries as educational source materials concerning contemporary Canadian Indigenous art.

description: Nanophotonic devices manipulate light at sub-wavelength scales, enabling tasks such as light concentration, routing, and filtering. Designing these devices is a challenging task. Traditionally, solving this problem has relied on computationally expensive, iterative methods. In recent years, deep learning techniques have emerged as promising tools for tackling the inverse design of nanophotonic devices. While several review articles have provided an overview of the progress in this rapidly evolving field, there is a need for a comprehensive tutorial that specifically targets newcomers without prior experience in deep learning. Our goal is to address this gap and provide practical guidance for applying deep learning to individual scientific problems. We introduce the fundamental concepts of deep learning and critically discuss the potential benefits it offers for various inverse design problems in nanophotonics. We present a suggested workflow and detailed, practical design guidelines to help newcomers navigate the challenges they may encounter. By following our guide, newcomers can avoid frustrating roadblocks commonly experienced when venturing into deep learning for the first time. In a second part, we explore different iterative and direct deep learning-based techniques for inverse design, and evaluate their respective advantages and limitations. To enhance understanding and facilitate implementation, we supplement the manuscript with detailed Python notebook examples, illustrating each step of the discussed processes. While our tutorial primarily focuses on researchers in (nano-)photonics, it is also relevant for those working with deep learning in other research domains. We aim at providing a solid starting point to empower researchers to leverage the potential of deep learning in their scientific pursuits.

description: We report an X-ray study of the evolved Galactic supernova remnant (SNR) G156.2+5.7 based on six pointing observations with Suzaku. The remnant's large extent (100$\arcmin$ in diameter) allows us to investigate its radial structure in the northwestern and eastern directions from the apparent center. The X-ray spectra were well fit with a two-component non-equilibrium ionization model representing the swept-up interstellar medium (ISM) and the metal-rich ejecta. We found prominent central concentrations of Si, S and Fe from the ejecta component; the lighter elements of O, Ne and Mg were distributed more uniformly. The temperature of the ISM component suggests a slow shock (610-960 km s$^{-1}$), hence the remnant's age is estimated to be 7,000-15,000 yr, assuming its distance to be $\sim$1.1 kpc. G156.2+5.7 has also been thought to emit hard, non-thermal X-rays, despite being considerably older than any other such remnant. In response to a recent discovery of a background cluster of galaxies (2XMM J045637.2+522411), we carefully excluded its contribution, and reexamined the origin of the hard X-ray emission. We found that the residual hard X-ray emission is consistent with the expected level of the cosmic X-ray background. Thus, no robust evidence for the non-thermal emission was obtained from G156.2+5.7. These results are consistent with the picture of an evolved SNR.

description: A new characterization of the Anderson phase transition, based on the response of the system to the boundary conditions is introduced. We change the boundary conditions from periodic to antiperiodic and look for its effects on the eigenstate of the system. To characterize these effects, we use the overlap of the states. In particular, we numerically calculate the overlap between the ground-state of the system with periodic and antiperiodic boundary conditions in one-dimensional models with delocalized-localized phase transitions. We observe that the overlap is close to one in the localized phase, and it gets appreciably smaller in the delocalized phase. In addition, in models with mobility edges, we calculate the overlaps between single-particle eigenstate with periodic and antiperiodic boundary conditions to characterize the entire spectrum. By this single-particle overlap, we can locate the mobility edges between delocalized and localized states.

description: Photocurrent-voltage characteristic (PC-V) is a method of determining the critical parameter in X-ray and gamma-ray detector plates, i.e., the carrier mobility - lifetime product, mt. We show on the (Cd,Mn)Te samples that the measurement results depend strongly on the surface treatment and the charge space distribution. The PC-V characteristics obtained for hv > Eg and hv ~ Eg indicated that etching with 20% HCl caused an appearance of a significant concentration of very shallow surface traps at the (Cd,Mn)Te sample surface. These traps seriously changed the measurements of PC-V characteristics and PC kinetics. We also noticed a small contribution of holes to photoconductivity in the PC kinetics. The PC-V characteristics measurements for hv > Eg may test the detector plate surface quality.

description: This study was conducted to examine more closely what has become one of the biggest challenges in secondary schools; the growing apathy of students who view curriculum as uninteresting and irrelevant. Qualitative approaches including case, narrative and design research were employed to examine this issue through the experiences of four different cohorts of students from two different schools and school divisions. The goal of this study was to better understand students' experiences of learning when educators changed fundamental aspects of the work that students in secondary schools have been asked to undertake. It is the contention of this thesis that significant progress can be made towards making schools more engaging places for learners when educators deliberately design learning experiences for students that are meaningful and relevant.
Multiscale conditional random fields for machine vision

description: We develop a single joint model which can classify images and label super-pixels, based on tree-structured conditional random fields (CRFs) derived from a hierarchical image segmentation, extending previous work by Reynolds and Murphy, and Plath and Toussaint. We show how to train this model in a weakly-supervised fashion, in which some of the images only have captions specifying which objects are present; this information is propagated down the tree and thus provides weakly labeled data at the leaves, which can be used to improve the performance of the super-pixel classifiers. After training, information can be propagated from the super-pixels up to the root-level image classifier (although this does not seem to help in practice compared to just using root-level features). We compare two kinds of tree: the standard one with pairwise potentials, and one based on noisy-or potentials, which better matches the semantics of the recursive partitioning used to create the tree. However, we do not find any significant difference between the two.

description: Η παρούσα εργασία ασχολείται µε τον προσδιορισμό της μάζας, της ακτίνας και τον συνδυασμό αυτών που δίνει ευσταθείς αστέρες νετρονίων. Για να επιτευχθεί αυτός ο σκοπός χρησιμοποιείται το σετ των διαφορικών εξισώσεων TOV, η επίλυση του οποίου µας δίνει πληροφορίες για τα προαναφερθέντα μεγέθη των αστέρων νετρονίων. Πιο συγκεκριμένα, στην επίλυση των εξισώσεων χρησιμοποιήθηκαν τρεις προσεγγίσεις ως προς την χρησιμοποιούμενη καταστατική εξίσωση που περιγράφει των αστέρα νετρονίων και συμβάλλει στην επίλυση του συστήματος διαφορικών εξισώσεων. Στη πρώτη προσέγγιση χρησιμοποιήθηκε μια πολυτροπική καταστατική εξίσωση για την περιγραφή του αστέρα, µε την µμέθοδο να λειτουργεί ικανοποιητικά µόνο για το κέντρο των αστέρων νετρονίων, δίνοντας το σετ μάζας ακτίνας για την ευστάθεια του. Στη δεύτερη προσέγγιση χρησιμοποιήθηκαν βαροτροπικές καταστατικές εξισώσεις σε αναλυτική μορφή, από συστήματα αστέρων νετρονίων, µε την κατάλληλη εναλλαγή καταστατικών εξισώσεων μεταξύ πυρήνα και κρούστας. Στην τρίτη προσέγγιση χρησιμοποιήθηκαν σετ δεδομένων πίεσης και ενεργειακής πυκνότητας, τα οποία οδήγησαν σε βαροτροπικές καταστατικές εξισώσεις µέσω του interpolation των δεδομένων αυτών. Οι δυο τελευταίες µμέθοδοι φαίνεται να λειτουργούν για το σύνολο του αστέρα δίνοντας µια ικανοποιητική προσέγγιση τόσο της ευστάθειας του αστέρα (μάζα-ακτίνα), όσο και της κρούστας του.
description: This master thesis, aims to analyse Mass and Radius of neutron stars and the specific set of them, which ensures stability. To do so, TOV equations are solved using three different approaches for the EOS which describes the star. Firstly, one poly-tropic EOS is used, which achieves good and logical results only for the core of the star (stability point), neglecting the crust of it. Secondly, barotropic EOS is used, in analytical form, in order to obtain results, from the solution of TOV differential equations, regarding mass and radius of the neutron star. At the end, the system of the aforementioned differential equations is solved in combination with a barotropic EOS constructed by interpolating given data for energy density and pressure of a neutron star. The last two approaches achieve satisfying results for mass and radius of the star, describing accurately the core and the crust of the star.

Subjects: Double sampling scheme; stratified random sampling; auxiliary variable; population mean and non-response

description: The present paper focuses on the use of double sampling scheme in stratified random sampling for estimating the population mean in the presence of non-response. Motivated by Khoshnevisan et al (2007), we have proposed a family of combined-type estimators of population mean utilizing the information on an auxiliary variable with the use of double sampling scheme under non-response. The optimum property of the proposed family has been discussed. An empirical study has also been carried out in the support of theoretical results.

description: We extend the classical phase-space distribution function to include the spin and electromagnetic fields coupling and derive the modified constitutive relations for charge current, energy-momentum tensor, and spin tensor. Because of the coupling, the new tensors receive corrections to their perfect fluid counterparts and make the background and spin fluid equations of motion communicate with each other. We investigate special cases which are relevant in high-energy heavy-ion collisions, including baryon free matter and large mass limit. Using Bjorken symmetries, we find that spin polarization increases with increasing magnetic field for an initially positive baryon chemical potential. The corrections derived in this framework may help to explain the splitting observed in Lambda hyperons spin polarization measurements.

description: We study special triple covers $f\colon T \to S$ of algebraic surfaces, where the Tschirnhausen bundle $\mathcal E = \left(f_*\mathcal O_T/\mathcal O_S\right)^\vee$ is a quotient of a split rank three vector bundle, and we provide several necessary and sufficient criteria for the existence. As an application, we give a complete classification of special triple planes, finding among others two nice families of K3 surfaces.

description: The objective of this research is to examine the discursive construction of Work Experience Education. Work Experience Education is an increasingly popular approach to vocational education in Alberta, Canada. It provides high school students opportunities to develop vocational skills, explore careers and in some cases gain hours towards trades certification, by working off-campus for employers in the business community while still gaining high school course credits for their efforts. Often viewed as a common sense approach, helping students develop employability skills through working with employers, Work Experience Education has largely evaded critical research. Through the use of Critical Discourse Analysis, both as a theoretical framework and as a method of inquiry, this study traces the growth of Work Experience Education and then examines the talk and policy involved its promotion and administration. Particular attention is given to the discourses or patterns of meaning that have come to dominate communication about Work Experience Education. This thesis highlights discursive tensions between managerial and marketing discourses in Work Experience Education and educational discourses about its plausibility as a form of learning, the accountability of participating schools and employers and the rights of student workers. In this thesis I examine the discourses of work and learning at play in Work Experience Education. I also raise questions regarding the impact of Work Experience Education on how educators understand the purpose of education more broadly.

description: If dark matter (DM) is millicharged or darkly charged, collective plasma processes may dominate momentum exchange over direct particle collisions. Plasma streaming instabilities can couple the momentum of the DM to counter-streaming baryons or other DM and result in the counter-streaming fluids coming to rest with each other, just as happens for baryonic collisionless shocks in astrophysical systems. While electrostatic plasma instabilities are highly suppressed by Landau damping when DM is millicharged, in the cosmological situations of interest, electromagnetic instabilities such as the Weibel can couple momenta, assuming that the linear instability saturates in the manner typically found for baryonic plasmas. We find that the streaming of DM in the pre-Recombination universe is affected more strongly by direct collisions than collective processes, validating previous constraints. However, when considering magnetized Weibel and Firehose instabilities, the properties of the Bullet Cluster merger are likely to be substantially altered if $[q_χ/m_χ] \gtrsim 10^{-12}-10^{-11}$, where $[q_χ/m_χ]$ is the charge-to-mass ratio of the DM relative to that of the proton. The Weibel growth rates are even faster in the case of a dark-$U(1)$ charge, potentially ruling out $[q_χ/m_χ] \gtrsim 10^{-14}$ in the Bullet Cluster system, in agreement with previous work. The strongest previous limits on millicharged DM (mDM) arise from considering the spin-down of galactic disks. We show that plasma instabilities or tangled background magnetic fields could lead to diffusive propagation of the DM, weakening these spin-down limits. Thus, plasma instabilities may place some of the most stringent constraints over much of the millicharged, and our results corroborate previous extremely stringent potential constraints on the dark-charged parameter space.
