description: Particle tracking plays a pivotal role in almost all physics analyses at the Large Hadron Collider. Yet, it is also one of the most time-consuming parts of the particle reconstruction chain. In recent years, the Exa.TrkX group has developed a promising machine learning-based pipeline that performs the most computationally expensive part of particle tracking, the track finding. As the pipeline obtains competitive physics performance on realistic data, accelerating the pipeline to meet the computational demands becomes an important research direction, that can be categorized as either software-based or hardware-based. Software-based inference acceleration includes model pruning, tensor operation fusion, reduced precision, quantization, etc. Hardware-based acceleration explores the usage of different coprocessors, such as GPUs, TPUs, and FPGAs. In this talk, we describe the Exa.TrkX pipeline implementation as a Triton Inference Server for particle tracking. Clients will send track-finding requests to the server and the server will return track candidates to the client after processing. The pipeline contains three discrete deep learning models and two CUDA-based algorithms. Because of the heterogeneity and dependency chain of the pipeline, we will explore different server settings to maximize the throughput of the pipeline, and we will study the scalability of the inference server and time reduction of the client.

description: Sarcasm is a peculiar form of sentiment expression, where the surface sentiment differs from the implied sentiment. The detection of sarcasm in social media platforms has been applied in the past mainly to textual utterances where lexical indicators (such as interjections and intensifiers), linguistic markers, and contextual information (such as user profiles, or past conversations) were used to detect the sarcastic tone. However, modern social media platforms allow to create multimodal messages where audiovisual content is integrated with the text, making the analysis of a mode in isolation partial. In our work, we first study the relationship between the textual and visual aspects in multimodal posts from three major social media platforms, i.e., Instagram, Tumblr and Twitter, and we run a crowdsourcing task to quantify the extent to which images are perceived as necessary by human annotators. Moreover, we propose two different computational frameworks to detect sarcasm that integrate the textual and visual modalities. The first approach exploits visual semantics trained on an external dataset, and concatenates the semantics features with state-of-the-art textual features. The second method adapts a visual neural network initialized with parameters trained on ImageNet to multimodal sarcastic posts. Results show the positive effect of combining modalities for the detection of sarcasm across platforms and methods.

description: About 40 years ago, since no viable candidate for "dark matter" was discovered, M. Milgrom and J. Bekenstein introduced a non-covariant modfication of gravitational theory ((MOND) to account for the anomalpous rotation curves of galaxies. Bekenstein and Sanders then developed a relativistically covariant form of the theory, called TeVeS, involvimg scalar and tensor fields which accounts for the rotation currves as well asfor the observed lensing of background radiation around galaxies without the introduction of "dark matter". The dynamical behavior of a particle in such a gravitational theory has recently been discussed by Horwitz, Gershon and Schiffer. In this paper we study the dynamics of the $N \geq 2$ particle problem in the framework of the TeVeS theory.

Social Determinants of International Students’ Mobility: Enhancing the Capabilities of PhD Students from Turkey
Creators: name: Dilek Fidler, Setenay
Publisher: name: University of Westminster
Year: 2019

description: Student mobility is part of the increasing internationalisation of higher education in the 21stcentury, being used by many as a stepping-stone for a career away from the country of birth. Despite acknowledgement of its contribution to human development and to a country’s economic development, this form of mobility is highly complex. For many of those involved, it represents a process of transformation underpinned by multiple factors and concluding with a decision whether or not to adopt migrant status. This research focuses on international PhD student mobility, a topic overlooked generally in the literature. The aim is to identify structural and agency factors influencing international mobility and to elicit how these impact on students’ capabilities to become mobile. From a theoretical perspective, this is achieved by drawing upon Structuration Theory together with the Capability Approach and applying these in the context of PhD students from Turkey in the UK. The findings, derived from 45 semi-structural interviews at macro and micro levels, reveal that political and socio-cultural factors are the main concerns of students with non-return plans to Turkey. Whilst political factors, particularly political freedoms and discrimination, lead to restrictions on academic and employment capabilities, socio-cultural ones, including family and societal pressure, as well as division and polarisation in Turkey, limit students’ capabilities in terms of freedom of life-style choice. With agency factors, ethnicity restricts the capability of expression of identity, whilst the level of acquired capability of independence varies according to gender. These differences provide evidence that agency factors play a significant role in mobility and thus it is essential that future work should include the capabilities of individuals, as well as micro level factors. Further, it is elicited that studying abroad enhances the capability of becoming a cosmopolitan citizen and, hence, being mobile. The conclusion drawn is that student mobility depends on whether a country can provide the opportunity for capabilities (freedoms/power) to flourish, with minimal perceived insecurity. For many participants, neither Turkey nor the UK was the country where they felt they could exploit their capabilities and they were looking for opportunities in third countries. This was owing to the lack of freedom in many aspects of life in Turkey and the strict migration policies’ in UK. The current study provides an extended framework for understanding the impact of structural and agency factors on mobility and the capabilities associated with mobility. Mobility groups identified are: for non-return students, Impo-Mobile, Voluntarily Mobile or Hyper Mobile; and for return students, Constant Immobile or Inconstant Immobile. The thesis can provide valuable pointers for further research and inform government policies on how to attract highly qualified individuals. 6

description: In holographic CFTs satisfying eigenstate thermalization, there is a regime where the operator product expansion can be approximated by a random tensor network. The geometry of the tensor network corresponds to a spatial slice in the holographic dual, with the tensors discretizing the radial direction. In spherically symmetric states in any dimension and more general states in 2d CFT, this leads to a holographic error-correcting code, defined in terms of OPE data, that can be systematically corrected beyond the random tensor approximation. The code is shown to be isometric for light operators outside the horizon, and non-isometric inside, as expected from general arguments about bulk reconstruction. The transition at the horizon occurs due to a subtle breakdown of the Virasoro identity block approximation in states with a complex interior.

CTD2022: Improving the performance of dealing with non-ideal tracks within ATLAS reconstruction

Publisher: name: Zenodo
Year: 2022

description: Within high transverse momentum jet cores, the separation between charged- particles is reduced to the order of the sensor granularity in the ATLAS tracking detectors, resulting in overlapping charged-particle measurements in the detector. This can degrade the efficiency of reconstructing charged-particle trajectories. This presentation identifies the issues within the current reconstruction algorithms that cause the reduction in reconstruction efficiency and explores an enhanced selection to recover some of the lost efficiency. The presentation will also discuss machine learning techniques to aid with recovering and removing bad quality track candidates.

description: This thesis presents how a right to water is explained and what this right consists of in international documents. Special importance is given to the United Nations Committee on Economic, Social and Cultural Rights’ General Comment No. 15 on the Right to Water. General Comment No. 15 emphasizes the right to water as a cornerstone for realizing all other human rights. Then transnational corporations’ (TNCs) social responsibility policies are presented, as TNCs are one of the biggest actors on the global market. What TNCs do to respect human rights and if they have any specific responsibilities in a human rights context, is also examined. This thesis also addresses TNCs’ activities and how they have an impact on a social and an environmental level and what obligations they have what concerns the right to water. Are companies obliged to respect water, and if not, what can they voluntarily do through their Corporate Social Responsibility (CSR) policies to assure that they won’t make it harder for people around the world to have access to clean water. In order to see how companies treat the environment (including water) and social issues through their CSR policies, a case study is conducted. A Finnish company (Metsä-Botnia) with rather good practices was chosen, as there has been much more public discussion about companies that harm the environment. The case study shows that companies that have good CSR policies and still make good profits exist. Finally, current issues and actions concerning water and what we all could do to respect it are discussed.

description: Many interesting phenomena in nature are described by stochastic processes with irreversible dynamics. To model these phenomena, we focus on a master equation or a Fokker-Planck equation with rates which violate detailed balance. When the system settles in a stationary state, it will be a nonequilibrium steady state (NESS), with time independent probability distribution as well as persistent probability current loops. The observable consequences of the latter are explored. In particular, cyclic behavior of some form must be present: some are prominent and manifest, while others are more obscure and subtle. We present a theoretical framework to analyze such properties, introducing the notion of "probability angular momentum" and its distribution. Using several examples, we illustrate the manifest and subtle categories and how best to distinguish between them. These techniques can be applied to reveal the NESS nature of a wide range of systems in a large variety of areas. We illustrate with one application: variability of ocean heat content in our climate system.

description: High-order sideband generation (HSG), as an analogue of the interband processes in high-harmonic generation (HHG) in solids, is a nonperturbative nonlinear optical phenomenon in semiconductors that are simultaneously driven by a relatively weak near-infrared (NIR) laser and a sufficiently strong terahertz (THz) field. We derive an explicit formula for sideband polarization vectors in a prototypical two-band model based on the saddle-point method. Our formula connects the sideband amplitudes with the laser-field parameters, electronic structures, and nonequilibrium dephasing rates in a highly nontrivial manner. Our results indicate the possibility of extracting information on band structures and dephasing rates from high-order sideband generation experiments with simple algebraic calculations. We also expect our approach to be useful on the quantitative understanding of the interband HHG.
CTD2022: Deep Learning Track Reconstruction for TeV-PeV Cosmic Rays in Space
Creators: name: Tykhonov, Andrii
Publisher: name: Zenodo
Year: 2022

description: Astroparticle physics is experiencing a new era of direct precision measurements in space at the highest energies. DArk Matter Particle Explorer (DAMPE) launched in 2015 has recently published the first results on Cosmic Ray proton and helium spectra up to 100 TeV and 80 TeV kinetic energy respectively. The successor mission to be launched in the nearest future, the High Energy Radiation Detector (HERD), is targeted further at the PeV scale. Track pattern recognition at DAMPE and HERD is a key factor limiting the measurement accuracy. Due to the vast multiplicity of secondary particles at high-energy interactions in the detector, the primary signal is heavily obscured, track reconstruction is becoming a needle in a haystack problem. New tracking techniques are critically demanded in order to fully uncover the science potential of DAMPE and HERD instruments. In this talk, we present the first findings of the PeVSPACE project, which employs state-of-the-art Deep Learning methods to fundamentally improve the quality of particle tracking for space atroparticle missions at the highest energies. We also give a brief overview of the DAMPE experiment and demonstrate the first application of the developed techniques to the analysis of the DAMPE data.

description: Strain-controlled isotropic compression gives rise to jammed packings of repulsive, frictionless disks with either positive or negative global shear moduli. We carry out computational studies to understand the contributions of the negative shear moduli to the mechanical response of jammed disk packings. We first decompose the ensemble-averaged, global shear modulus as $\langle G\rangle = (1-{\cal F}_-) \langle G_+ \rangle + {\cal F}_- \langle G_-\rangle$, where ${\cal F}_-$ is the fraction of jammed packings with negative shear moduli and $\langle G_+\rangle$ and $\langle G_-\rangle$ are the average values from packings with positive and negative moduli, respectively. We show that $\langle G_+\rangle$ and $\langle|G_-|\rangle$ obey different power-law scaling relations above and below $pN^2 \sim 1$. We then calculate analytically that ${\cal P}(G)$ is a Gamma distribution in the $pN^2 \ll 1$ limit. As $pN^2$ increases, the skewness of ${\cal P}(G)$ decreases and ${\cal P}(G)$ becomes a skew-normal distribution with negative skewness in the $pN^2 \gg 1$ limit. We also partition jammed disk packings into subsystems using Delanunay triangulation of the disk centers to calculate local shear moduli. We show that the local shear moduli defined from groups of adjacent triangles can be negative even when $G > 0$. The spatial correlation function of local shear moduli $C({\vec r})$ displays weak correlations for $pn_{\rm sub}^2 < 10^{-2}$, where $n_{\rm sub}$ is the number of particles within each subsystem. However, $C({\vec r})$ begins to develop long-ranged spatial correlations with four-fold angular symmetry for $pn_{\rm sub}^2 \gtrsim 10^{-2}$.

description: We numerically study the statistical fluctuations of photonic band gaps in ensembles of stealthy hyperuniform disordered patterns. We find that at low stealthiness, where correlations are weak, band gaps of different system realizations appear over a wide frequency range, are narrow, and generally do not overlap. Interestingly, above a critical value of stealthiness $χ\gtrsim 0.35$, the bandgaps become large and overlap significantly from realization to realization, while a second gap appears. These observations extend our understanding of photonic bandgaps in disordered systems and provide information on the robustness of gaps in practical applications.

They reveal statistics effects and two-particle interference, and offer a decoherence-free probe of the coherence properties of light sources. In the quantum Hall edge channels, the concept of quantum optics can transposed to electrons, and an analogous two-particle interferometry can be developed, in order to characterize single-electron states. We review in this article the recent experimental and theoretical progress on this topic.

description: Effective field theories have often been applied to systems with deeply inelastic reactions that produce particles with large momenta outside the domain of validity of the effective theory. The effects of the deeply inelastic reactions have been taken into account in previous work by adding local anti-Hermitian terms to the effective Hamiltonian. Here we show that when multi-particle systems are considered, an additional modification is required in equations governing the density matrix. We define an effective density matrix by tracing over the states containing high-momentum particles, and show that it satisfies a Lindblad equation, with local Lindblad operators determined by the anti-Hermitian terms in the effective Hamiltonian density.

CTD2022: The Tracking at Belle II
Creators: name: Zlebcik, Radek
Publisher: name: Zenodo
Year: 2022

description: The tracking system of Belle II consists of a silicon vertex detector (VXD) and a cylindrical drift chamber (CDC), both operating in a magnetic field created by the main solenoid of 1.5 T and final focusing magnets. The experiment is taking data since 2019 with high-quality and stable tracking performance. We present the tracking-based calibration of the beams characteristics and their interaction region, which are critical for the many high-precision measurements in the physics program. We also discuss possible improvements in the silicon strip vertex detector track finding, exploiting Hough transformation instead of the current one.

description: Molecular Dynamic and Monte Carlo studies are performed in a family of core-softened (CS) potential, composed by two length scales: a repulsive shoulder at short distances and the another a variable scale, that can be repulsive or strongly attractive depending on the parameters used. The density, diffusion and structural anomalous regions in the pressure versus temperature phase diagram shrink in pressure as the system becomes more attractive. The liquid-liquid transition appears as a consequence of the non monotonic behavior of the density versus pressure isotherms with the increase of the attraction well. We found that the liquid-gas phase transition is Ising-like for all the CS potentials and its critical temperature increases with the increase of the attraction. No Ising-like behavior for the liquid-liquid phase transition was detected in the Monte Carlo simulations what might be due to the presence of stable solid phases.

description: We report here on the ability of elastic light scattering in discriminating Gram+, Gram-and yeasts at an early stage of growth (6h). Our technique is non-invasive, low cost and does require neither skilled operators nor reagents. Therefore it is compatible with automation. It is based on the analysis of the scattering pattern (scatterogram) generated by a bacterial microcolony growing on agar, when placed in the path of a laser beam. Measurements are directly performed on closed Petri dishes. The characteristic features of a given scatterogram are first computed by projecting the pattern onto the Zernike orthogonal basis. Then the obtained data are compared to a database so that machine learning can yield identification result. A 10-fold cross-validation was performed on a database over 8 species (15 strains, 1906 scatterograms), at 6h of incubation. It yielded a 94% correct classification rate between Gram+, Gram-and yeasts. Results can be improved by using a more relevant function basis for projections, such as Fourier-Bessel functions. A fully integrated instrument has been installed at the Grenoble hospital's laboratory of bacteriology and a validation campaign has been started for the early screening of SA and MRSA (Staphylococcus aureus, methicillin-resistant S. aureus) carriers. Up to now, all the published studies about elastic scattering were performed in a forward mode, which is restricted to transparent media. However, in clinical diagnostics, most of media are opaque, such as blood-supplemented agar. That is why we propose a novel scheme capable of collecting back-scattered light which provides comparable results.

description: Indirect reciprocity is a mechanism that explains large-scale cooperation in humans. In indirect reciprocity, individuals use reputations to choose whether or not to cooperate with a partner and update others' reputations. A major question is how the rules to choose their actions and the rules to update reputations evolve. In the public reputation case, where all individuals share the evaluation of others, social norms called Simple Standing (SS) and Stern Judging (SJ) have been known to maintain cooperation. However, in the case of private assessment where individuals independently evaluate others, the mechanism of maintenance of cooperation is still largely unknown. This study theoretically shows for the first time that cooperation by indirect reciprocity can be evolutionarily stable under private assessment. Specifically, we find that SS can be stable, but SJ can never be. This is intuitive because SS can correct interpersonal discrepancies in reputations through its simplicity. On the other hand, SJ is too complicated to avoid an accumulation of errors, which leads to the collapse of cooperation. We conclude that moderate simplicity is a key to success in maintaining cooperation under the private assessment. Our result provides a theoretical basis for evolution of human cooperation.

description: An interaction of upstream extra particles with a monolayer highly-ordered complex plasma is studied. A principally new abnormal turbulent wake formed behind the supersonic upstream particle is discovered. An anomalous type of the turbulence wake clearly manifests in anomalously low thermal diffusivity and two orders of magnitude larger particle kinetic temperature compared to that of the 'normal' wake (Mach cone) observed by Du et al [Europhys. Lett. 99, 55001 (2012)].

Harry Partch: A Catalyst for Queer Compositionism
Creators: name: Saunders, William
Publisher: name: University of Westminster
Year: 2019

description: My encounter with Harry Partch - mediated through recordings, ﬁlms, and sleeve photographs - is taken as an interpellative hail (Althusser, 2014) to inquire into his legacy. As a queer musician, I re-articulate Partch’s volatility and (apparent) inability to collaborate, positing that he presented his personhood as hybridised with his self-built instruments, precarious home-studios, audio equipment, microtonal systems, published writings, records, sleeve notes, etc. I champion this hybridised personhood as a queer expression of his epistemology of the closet (Sedgwick, 2008), asking whether this notion applies to what I have coined a queer compositionist stance in collaborative performance projects. Partch collaborated intimately with the human and nonhuman agents (Latour, 2007) that he assembled into his life’s work. I see his protectionism of this assemblage not simply as outsiderism, but as a queer utopian message to arm oneself against the inertia (Becker, 1995) of normalising forces. A methodology centred around Bruno Latour supports this notion. In this regard, I follow the lead of Benjamin Piekut’s scholarship on musical experimentalism. I ask whether the kind of networked hybridity that Latour has us pay attention to could relate to queer negotiations of the closet. Can a re-articulation of Harry Partch’s life’s work as a mediation of his personhood foreground ephemeral evidence (Muñoz 1996) of his ambivalent use of outsider labels? How can this speculation be used as a catalyst for a queer orientation of collaborative performance projects? The queer Partch that emerges from these questions haunts a series of collaborative performance projects that have offered practice-based contexts for an enquiry into my proposed queer compositionist stance. This stance foregrounds a quiet insistence on project-speciﬁc musical principles, not based on authorial signature, but on closet-like assemblages of conceptually integrated elements. In my accounts of the project’s developments, I have exposed queer compositionism as offering a unique contribution to hauntological approaches to music production.

description: We demonstrate an optical fiber fault location method based on the frequency response of the modulated fiber optical backscattered signal in a steady state low-frequency step regime. Careful calibration and measurement allows for the reconstruction of the fiber transfer function, which, associated to its mathematical model, is capable of extracting the fiber characteristics. The technique is capable of identifying non-reflective fault events in an optical fiber link and is perfectly compatible with previous methods that focus on the reflective events. The fact that the recuperation of the complex signal is performed in the frequency domain and not via a Fourier Transform enables the measurements to overcome the spatial resolution limitation of Fourier Transform incoherent-OFDR measurements even with frequency sweep ranges down to 100-100000 Hz. This result is backed up by a less than 10 meters difference in fault location when compared to standard OTDR measurements.

description: Three dimensional models of insect specimens offer the potential for a variety of research applications, including taking morphological and trait measurements of insects and automated species identification. Yet high-quality 3d models are challenging to create because of the specimens’ small size. Here we overcome this challenge by creating 3d models using focal stacking to take high-resolution images of bee specimens. Sets of 3d images are processed using Zerene Stacker and Photoshop, and the 3d models are created using Agisoft Metashape. Our protocol can be used for both larger insect specimens, like bumble bees and carpenter bees, and small- and medium-sized specimens, such as mason and sweat bees. This protocol is being used by members of the Cheadle Center for Biodiversity and Ecological Restoration at the University of California, Santa Barbara, and is based on a protocol developed by members of the Big-Bee project.
Brueckner $G$-matrix approach to two-dimensional Fermi gases with the finite-range attractive interaction

description: Two-dimensional spin-1/2 fermions with the finite-range interaction are theoretically studied. Characterizing the attractive interaction in terms of the scattering length and the effective range, we discuss the finite-range effects on the ground-state properties in this system. The Brueckner $G$-matrix approach is employed to analyze the finite-range effects on an attractive Fermi-polaron energy and the equation of state throughout the BEC-BCS crossover in two dimensions, which can be realized in the population-imbalanced and -balanced cases between two components, respectively. The analytical formulae for these ground states obtained in this study would be useful for understanding many-body phenomena with finite-range interactions in low-dimensional systems.

description: Several years ago, one of us, having noticed that inexperienced scientists tend to make largely the same mistakes while writing their first papers, was compelled to write a one-page note summarizing some dos and don'ts intended to help take care of common problems before they occur. Since these days the majority of research papers are written collaboratively by groups of co-authors, we are compelled to extend these recommendations to collaborative writing as we observe groups of co-authors falling into the same traps again and again.

description: With the aim of improving our knowledge about the nature of the progenitors of low-luminosity Type II plateau supernovae (LL SNe IIP), we made radiation-hydrodynamical models of the well-sampled LL SNe IIP 2003Z, 2008bk and 2009md. For these three SNe we infer explosion energies of $0.16$-$0.18$ foe, radii at explosion of $1.8$-$3.5 \times 10^{13}$ cm, and ejected masses of $10$-$11.3$\Msun. The estimated progenitor mass on the main sequence is in the range $\sim 13.2$-$15.1$\Msun\, for SN 2003Z and $\sim 11.4$-$12.9$\Msun\, for SNe 2008bk and 2009md, in agreement with estimates from observations of the progenitors. These results together with those for other LL SNe IIP modelled in the same way, enable us also to conduct a comparative study on this SN sub-group. The results suggest that: a) the progenitors of faint SNe IIP are slightly less massive and have less energetic explosions than those of intermediate-luminosity SNe IIP, b) both faint and intermediate-luminosity SNe IIP originate from low-energy explosions of red (or yellow) supergiant stars of low-to-intermediate mass, c) some faint objects may also be explained as electron-capture SNe from massive super-asymptotic giant branch stars, and d) LL SNe IIP form the underluminous tail of the SNe IIP family, where the main parameter "guiding" the distribution seems to be the ratio of the total explosion energy to the ejected mass. Further hydrodynamical studies should be performed and compared to a more extended sample of LL SNe IIP before drawing any conclusion on the relevance of fall-back to this class of events.

CTD2022: Fast and flexible data structures for the LHCb run 3 software trigger
Creators: name: Esen, Sevda
Publisher: name: Zenodo
Year: 2022

description: Starting this year, the upgraded LHCb detector will collection data with a pure software trigger. In its first stage, reducing the rate from 30MHz to about 1MHz, GPUs are used to reconstruct and trigger on B and D meson topologies and high-pT objects in the event. In its second stage, a CPU farm is used to reconstruct the full event and perform candidate selections, which are persisted for offline use with an output rate of about 10GB/s. Fast data processing, flexible and custom-designed data structures tailored for SIMD architectures and efficient storage of the intermediate data at various steps of the processing pipeline onto persistent media, e.g. tapes is essential to guarantee the full physics program of LHCb. In this talk, we will present the event model and data persistency developments for the trigger of LHCb in run 3. Particular emphasize will be given to the novel software-design aspects with respect to the Run 1+2 data taking, the performance improvements which can be achieved and the experience of restructuring a major part of the reconstruction software in a large HEP experiment.
CTD2022: Track Reconstruction at the Electron-Ion Collider
Creators: name: Li, Shujie
Publisher: name: Zenodo
Year: 2022

description: During the past year, substantial progress has been made on the design of Detector 1 for the Electron-Ion Collider (EIC). All proposed detector configurations used a combination of silicon trackers and gas detectors for particle tracking and vertex reconstruction. A DD4hep + Gaudi + Acts + EDM4hep simulation and reconstruction framework was developed by the ATHENA proposal collaboration to demonstrate a tracking performance consistent with the EIC physics requirements. In this talk, I will go over the ATHENA tracking system configuration, reconstruction studies with Acts, and our plan to further this effort for the official EIC Project 'Detector 1'.

description: Link-flooding attacks have the potential to disconnect even entire countries from the Internet. Moreover, newly proposed indirect link-flooding attacks, such as 'Crossfire', are extremely hard to expose and, subsequently, mitigate effectively. Traffic Engineering (TE) is the network's natural way of mitigating link overload events, balancing the load and restoring connectivity. This work poses the question: Do we need a new kind of TE to expose an attack as well? The key idea is that a carefully crafted, attack-aware TE could force the attacker to follow improbable traffic patterns, revealing his target and his identity over time. We show that both existing and novel TE modules can efficiently expose the attack, and study the benefits of each approach. We implement defense prototypes using simulation mechanisms and evaluate them extensively on multiple real topologies.

description: In this paper we show that using frame-like gauge invariant formulation for the massive bosonic and fermionic fields in three dimensions the free Lagrangians for these fields can be rewritten in the explicitly gauge invariant form in terms of the appropriately chosen set of gauge invariant objects. This in turn opens the possibility to apply the Fradkin-Vasiliev formalism to the investigation of possible interactions of such fields.
