description: We analyze mathematical and physical properties of a previously introduced [J. Phys. A47, 115302 (2014)] family of $U(4)$ coherent states (CS). They constitute a matrix version of standard spin $U(2)$ CS when we add an extra (pseudospin) dichotomous degree of freedom: layer, sublattice, two-well, nucleon, etc. Applications to bilayer quantum Hall systems at fractions of filling factor $ν=2$ are discussed, where Haldane's sphere picture is generalized to a Grassmannian picture. We also extend Wehrl's definition of entropy from Glauber to Grassmannian CS and state a conjecture on the entropy lower bound.

description: As part of the Institute of Higher Studies in Advanced Practical (Istituto di Studi Superiori Pratici e di Perfezionamento) in 1860 was founded in Florence the Section of Law Studies, reserved for graduates in Law who, before being admitted to legal professions (lawyers, attorneys, judges), had to carry out a practice period. The lack of resources (human and financial) and the inadequate connections between the Institute and the College of Lawyers of Tuscany combined to bring about its failure, and in 1867 the Section was closed. Nevertheless, it represents an interesting (and ambitious) attempt to bridge the gap between academia and professions – that is, between theory and practice – which was already betrayed by insiders.

The role of stellar relaxation in the formation and evolution of the first massive black holes

description: We present calculations on the formation of massive black holes with 10^5 Msun at z > 6 that can be the seeds of supermassive black holes at z > 6. Under the assumption of compact star cluster formation in merging galaxies, star clusters in haloes of 10^8 ~ 10^9 Msun can undergo rapid core-collapse leading to the formation of very massive stars (VMSs) with ~1000 Msun which directly collapse into black holes with similar masses. Star clusters in halos of > 10^9 Msun experience type-II supernovae before the formation of VMSs due to long core-collapse time scales. We also model the subsequent growth of black holes via accretion of residual stars in clusters. 2-body relaxation efficiently re-fills the loss cones of stellar orbits at larger radii and resonant relaxation at small radii is the main driver for accretion of stars onto black holes. As a result, more than ninety percent of stars in the initial cluster are swallowed by the central black holes before z=6. Using dark matter merger trees we derive black hole mass functions at z=6-20. The mass function ranges from 10^3 to 10^5 Msun at z ~ 4*10^8 Msun at z ~ 20 successfully leads to the formation of >~ 10^5 Msun BHs by z >~ 10 which can be the potential seeds of supermassive black holes seen today.

Career paths of power five athletic directors: A social network analysis
Creators: name: Dickman, Grace Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The purpose of this study is to explore the career paths of Division I Power Five athletic directors. Using social network analysis, this research builds a network of institutions of higher learning that are connected by career position changes of current Power Five athletic directors. The goals of the study are to investigate whether there are patterns in career paths, and if certain institutions are hubs and authorities for athletic directors. The research suggested that patterns in career paths have changed for athletic directors, and there are differences between the paths of male and female athletic directors. The hubs in the network propelled athletic directors into high ranking positions at their next institution, and authorities hired athletic directors in high positions. Influential institutions in the network were connected to other influencers, as well as sharing hiring patterns with hubs and authorities. Influencers did not have a high volume of hires or athletic directors leaving for other jobs, but when they did, it was usually either at the senior associate athletic director level or athletic director level. They also often hired from and sent athletic directors off to other Power Five institutions.
The Northwest passage
Creators: name: Harris, Helyett
Publisher: name: No Publisher Supplied
Year: 2013

description: The Arctic region could be a future geopolitical battleground. Arctic temperatures have risen faster than anywhere else on Earth, which has led to an unprecedented melting of the polar ice cap. The thawing ice will have profound consequences for the region, and global politics generally, with the opening of strategic waterways for shipping, and a drive to claim rights to the wealth of natural resources that lie beneath Arctic waters. One such waterway is the Northwest Passage, a strategic route connecting the Atlantic and Pacific Oceans through the Canadian Arctic Archipelago. Since the European discovery of North America, adventurous seafarers have dreamed of a Northwest Passage that would commercially link Europe and Asia. Unfortunately, ice blockades and poor weather conditions proved formidable barriers, and over the course of four centuries, many tried, failed, and died seeking a westerly route. Not until 1906 was the waterway first traversed by Norwegian explorer, Roald Amundsen, but even then the Northwest Passage was not commercially viable. Today, as a result of decades-long climate warming, Arctic ice is declining in both thickness and extent. The future use of the Northwest Passage could greatly reduce navigation times and shipping costs. This study examines the issues related to a navigable waterway, including environmental challenges, economic and commercial benefits, strategic and security implications, and relations between the United States and Canada. The Northwest Passage is an integral part of Canada's national identity and a potential source of contention in U.S.-Canada relations. Canada maintains that the waterway falls within historic internal waters, and the U.S. argues that the Passage is an international strait. This dissertation explores several possible governance structures and concludes that some sort of joint management arrangement between Canada and the United States is the most likely outcome.
Clergy and Fiscal Reform in Eighteenth-Century Spain
Creators: name: Guasti, Niccolò

Year: 2015

description: This study examines the continuities that can be found within the Spanish taxation system during the eighteenth century. Despite the War of the Spanish Succession and the Nueva Planta, the Bourbons did not abolish the taxation system inherited from the Habsburgs, but tried as far as possible to improve it. On the other hand, an examination of the eighteenth century reforms applied to economy and taxation allows the wider question of the roots of the Iberian Ilustración to be tackled from an original perspective. It stands to reason that the Ilustración was the result of the confluence of a plurality of traditions, currents of thought and branches of knowledge, old and new. Prominent among these were the proyectismo heir to the seventeenth-century arbitrismo; the persistent regalist tradition revitalized by the reforming trends within Catholicism ; natural law; and, lastly, political (or “civil”) economy, the scientific and academic status of which was defined precisely during the reign of Charles III thanks to the Sociedades Económicas de Amigos del País and the creation of the first university chairs in Saragossa. This (and other) theoretical systems were combined and hybridized by the ilustrados according to their political struggle and related reformatory planning – which was sometimes confused, but at other times was more coherent and effective: the aim was to correct some of the most evident injustices in the coeval class-based society. The vitality of the debates on the fiscal reform shows that a sector of the Spanish ruling classes tried to change the Old Regime society from the top, keenly aware of the link between the reform of the agrarian world and the shift of the levy from indirect taxes (excise taxes and customs duties) to direct ones weighing on real estate and incomes in general. If eventually the last generation of ilustrados (including the pro-Bonapartist afrancesados) and the first generation of Spanish liberals failed in the objective of strengthening the class of small landowners and tenants to whom they wanted to entrust the re-launch of the Iberian economy, this was the result of the capacity for resistance of the privileged classes, who proved to be refractory to change.

description: The existence of rational points on Kummer varieties associated to 2-coverings of abelian varieties over number fields can sometimes be proved through the variation of the Selmer group in the family of quadratic twists of the underlying abelian variety, using an idea of Swinnerton-Dyer. Following Mazur and Rubin, we consider the case when the Galois action on the 2-torsion has a large image. Under mild additional hypotheses we prove the Hasse principle for the associated Kummer varieties assuming the finiteness of relevant Shafarevich-Tate groups.

description: Per-object distance estimation is critical in surveillance and autonomous driving, where safety is crucial. While existing methods rely on geometric or deep supervised features, only a few attempts have been made to leverage self-supervised learning. In this respect, our paper draws inspiration from Masked Image Modeling (MiM) and extends it to multi-object tasks. While MiM focuses on extracting global image-level representations, it struggles with individual objects within the image. This is detrimental for distance estimation, as objects far away correspond to negligible portions of the image. Conversely, our strategy, termed Masked Object Modeling (MoM), enables a novel application of masking techniques. In a few words, we devise an auxiliary objective that reconstructs the portions of the image pertaining to the objects detected in the scene. The training phase is performed in a single unified stage, simultaneously optimizing the masking objective and the downstream loss (i.e., distance estimation).
 We evaluate the effectiveness of MoM on a novel reference architecture (DistFormer) on the standard KITTI, NuScenes, and MOTSynth datasets. Our evaluation reveals that our framework surpasses the SoTA and highlights its robust regularization properties. The MoM strategy enhances both zero-shot and few-shot capabilities, from synthetic to real domain. Finally, it furthers the robustness of the model in the presence of occluded or poorly detected objects. Code is available at https://github.com/apanariello4/DistFormer

Grief, Burnout, and Teacher Well-Being

Publisher: name: University of Alberta Library
Year: 2022

The Covid-19 pandemic has had various effects on social, economic, and political aspects of our world. Specifically in the realm of education, teachers have been left to navigate the uncharted territory of teaching exclusively online in the first phase of the virus, beginning in March 2020, then intermittently teaching online during the 2020-2021 school year, then dealing with the impact of Covid-19 on absenteeism, student apathy, and disengagement during the 2021-2022 school year. The impact on teachers’ overall mental health and well-being was vast, and subsequent feelings of grief and burnout were experienced by many. In this qualitative study, based on grounded theory methodology, a small purposeful sampling of teachers volunteered to share their experiences of teaching in the pandemic, and to what extent they experienced the stages of grief (Kübler-Ross, 1969) and indicators of burnout (Nagoski & Nagoski, 2019). Six participants were interviewed, data collected, transcribed, analyzed, and coded to identify themes. Teaching experience varied among participants, but many similarities existed. The final part of the research and questioning centered around supports administration and leadership, both divisional and local, could offer to mitigate some of the symptoms of grief and burnout being

experienced. Despite the variance in experience with grief and burnout, each participant identified with the frameworks presented, while continuing to hope for a better future for their teaching experience and in the greater world of education.
Transient Dynamics of d-wave Superconductors after a Sudden Excitation

description: Motivated by recent ultafast pump probe experiments on high-temperature superconductors, we discuss the transient dynamics of a d-wave BCS model after a quantum quench of the interaction parameter. We find that the existence of gap nodes, with the associated nodal quasiparticles, introduces a dissipation channel which makes the dynamics much faster than in the conventional s-wave model. For every value of the quench parameters, the superconducting gap rapidly converges to a stationary value smaller than the one at equilibrium. Using a sudden approximation for the gap dynamics, we find an analytical expression for the reduction of spectral weight close to the nodes, which is in qualitative agreement with recent experiments.

“Se è da fare opera da volgere Arno”. Léonard au service du projet de détournement de l’Arno
Creators: name: D'Errico, Dora
Publisher: name: Cromohs - Cyber Review of Modern Historiography
Year: 2015

description: The project to divert the flow of the Arno occupied Leonardo da Vinci’s mind during the troubled years of 1503-1504, as he was commissioned by the city of Florence to investigate its feasibility, and to study its military consequences in the war against Pisa. Aside from the “Leonardian” aspects of the project (such as the dream of mastering the power of nature, or the fascination for spirals and waves, etc.), this article sets out to cast some light on its historical and political context. Indeed, the reading of the verbali gathered together in the Consulte e Pratiche della Republica fiorentina authorizes us to see Leonardo from a different perspective, and to ask some interesting questions: how does the idea of diverting the river echo the imagination of the men of his time ? What were the real aims of the city in hiring Leonardo: to use his genius, or only his name and reputation as Borgia’s military engineer? And how, finally, does the Leonardian project match Piero Soderini’s political vision of Florence’s country planning ?

Leonardo da Vinci à Milan et le condottiere Pietro Monte

Publisher: name: Cromohs - Cyber Review of Modern Historiography
Year: 2015

description: Pietro Monte and Leonardo Da Vinci lived in Milan at about the same time around 1495 and from a note in the Codex Atlanticus, one can deduce the familiarity of the two Tuscans. This paper tries to explore the nature of the collaboration between the Condottiere who died at Agnadello and the famous inventor in terms of weaponry and tactics. They were both involved in inventing a latin vocabulary to write about the subject and shared thougts about landsknechten’s techniques. It also seems that a lost leonardian treatise quoted by some authors was in close relation with Pietro Monte’s writings in its Collectanea. If we add to these remarks the fact that Leonardo and Monte were both studying internal and external ballistics in practical and philosophical terms, it might be the case that such a collaboration has to be completely reassessed in the future.

For these quantities, whose contributions are often localized in small portions of the Brillouin zone, adaptive integration is especially relevant. Our implementation, the woptic package, is tied into the wien2wannier framework and allows including a many-body self energy, e.g. from dynamical mean-field theory (DMFT). Wannier functions and dipole matrix elements are computed with the DFT package Wien2k and Wannier90. For illustration, we show DFT results for fcc-Al and DMFT results for the correlated metal SrVO$_3$.

description: Surface waves on both superfluid 3He and 4He were examined with the premise, that these inviscid media would represent ideal realizations for this fluid dynamics problem. The work on 3He is one of the first of its kind, but on 4He it was possible to produce much more complete set of data for meaningful comparison with theoretical models. Most measurements were performed at the zero temperature limit, meaning T < 100 mK for 4He and T ~ 100 μK for 3He. Dozens of surface wave resonances, including up to 11 overtones, were observed and monitored as the liquid depth in the cell was varied. Despite of the wealth of data, perfect agreement with the constructed theoretical models could not be achieved.
Platforms and Outsiders in Party Networks: The Evolution of the Digital Political Advertising Network

description: Scholars seldom examine the companies that campaigns hire to run digital advertising. This thesis presents the first network analysis of relationships between federal political committees (n = 2,077) and the companies they hired for electoral digital political advertising services (n = 1,034) across 13 years (2003–2016) and three election cycles (2008, 2012, and 2016). The network expanded from 333 nodes in 2008 to 2,202 nodes in 2016. In 2012 and 2016, Facebook and Google had the highest normalized betweenness centrality (.34 and .27 in 2012 and .55 and .24 in 2016 respectively). Given their positions in the network, Facebook and Google should be considered consequential members of party networks. Of advertising agencies hired in the 2016 electoral cycle, 23% had no declared political specialization and were hired disproportionately by non-incumbents. The thesis argues their motivations may not be as well-aligned with party goals as those of established political professionals.
Relaxation of an electron wave packet at the quantum Hall edge at filling factor 2

description: In this work, we address the recent experiment [S. Tewari et al., arXiv:1503.05057v1], where the suppression of phase coherence of a single-electron wave packet created at the edge of a quantum Hall (QH) system at filling factor 2 has been investigated with the help of an electronic Mach-Zehnder (MZ) interferometer. The authors of the experiment have observed an unexpected behavior of phase coherence, that saturates at high energies instead of vanishing, presumably suggesting the relaxation of a wave packet to the ground state before it arrives to the MZ interferometer. Here, we theoretically investigate this situation using the model of edge states [I. P. Levkivskyi, E. V. Sukhorukov, Phys. Rev. B 78, 045322 (2008)], which accounts for the strong Coulomb interaction between the two electron channels at the edge of a QH system. We conclude that the observed phenomenon cannot be explained within this model for the reason that under an assumption of linearity of the electron spectrum at low energies the system remains integrable in terms of the collective charge excitations, and therefore full relaxation to the ground state is not possible, despite strong interactions. As a result, the degree of the phase coherence decreases with energy of the initial state in a power-law manner. Since this does not happen in the experiment, a new physical phenomenon may take place at the edge of a QH state, which deserves further investigations. We support our findings by calculating the energy distribution and the Wigner function of the outgoing non-equilibrium state of the single-electron wave packet.

The multilayer shallow water system in the limit of small density contrast

description: We study the inviscid multilayer Saint-Venant (or shallow-water) system in the limit of small density contrast. We show that, under reasonable hyperbolicity conditions on the flow and a smallness assumption on the initial surface deformation, the system is well-posed on a large time interval, despite the singular limit. By studying the asymptotic limit, we provide a rigorous justification of the widely used rigid-lid and Boussinesq approximations for multilayered shallow water flows. The asymptotic behaviour is similar to that of the incompressible limit for Euler equations, in the sense that there exists a small initial layer in time for ill-prepared initial data, accounting for rapidly propagating "acoustic" waves (here, the so-called barotropic mode) which interact only weakly with the "incompressible" component (here, baroclinic).

description: ADHERENCE AND COMPLIANCE TO A 6-MONTH WALKING INTERVENTION FOR INDIVIDUALS DIAGNOSED WITH SCHIZOPHRENIA SPECTRUM DISORDERS      (Under the direction of Dr. Claudio L. Battaglini)      PURPOSE: To assess adherence and compliance of individuals diagnosed with Schizophrenia Spectrum Disorders (SSDs) to a 6-month, progressive walking program. Changes in physical and psychological outcomes were also evaluated. METHODS: Subjects attended group-based walking sessions biweekly at local mental health clinics. RESULTS: Subjects attended 34% of group walks and wore their Fitbits 51% of the prescribed time. Compliance to individualized prescribed heart rate training ranges for home-based and group-based active minutes were low (0.6, and 4.9% respectively). However, subjects overall active minutes throughout the study surpassed the prescribed dosage, achieving 179% prescribed active minutes, which may help explain significant improvements in the 6-minute walk test distances (pre 377 ± 112m, post 466 ± 128 intervention, p < 0.001, ES = 0.142). CONCLUSION: Despite low adherence to group walking and compliance to HR training zones, significant improvements in cardiorespiratory fitness were observed, likely from greater participation in active minutes than prescribed.

«Ordine di balestrieri a cavalla da campo aperto, e tutti voltino a sinistra»: Léonard et la caracole d’après les dessins du manuscrit B
Creators: name: Deruelle, Benjamin
Publisher: name: Cromohs - Cyber Review of Modern Historiography
Year: 2015

description: Today, Leonardo da Vinci embodies the figure of an accomplished artist, horrified by war, or, as he described it, a “pazzia bestiallissima”. However, he presented himself as a military engineer to the duke of Milan around 1482, and served Venice and Cesare Borgia a few years later. Leonardo’s manuscripts are full of drawings of arms, machines of war, fortifications and comments on how to construct them. Codex B occupies a special place among these manuscripts. Written during the 1480s, when Leonardo was in the service of Ludovico Sforza, warfare is a predominant theme throughout the manuscript. Indeed, in the midst of the drawings in Codex B, there are two cavalry orders representing what we have to call the “caracole”. Nevertheless, the caracole is thought to have been introduced into European warfare by the German Reiters in the middle of the sixteenth century. These few points drawn on paper question the military knowledge and practices of the end of the fifteenth century, and the changes in the art of war in this Italian laboratory at the same time.

description: We prove that for every $p,q\in[1,\infty]$ and every random matrix $X=(X_{i,j})_{i\le m, j\le n}$ with iid centered entries satisfying the regularity assumption $\|X_{i,j}\|_{2ρ} \le α\|X_{i,j}\|_ρ$ for every $ρ\ge 1$, the expectation of the operator norm of $X$ from $\ell_p^n$ to $\ell_q^m$ is comparable, up to a constant depending only on $α$, to \[ m^{1/q}\sup_{t\in B_p^n}\Bigl\|\sum_{j=1}^nt_jX_{1,j}\Bigr\|_{ q\wedge \operatorname{Log} m} +n^{1/p^*}\sup_{s\in B_{q^*}^m}\Bigl\|\sum_{i=1}^{m} s_iX_{i,1}\Bigr\|_{ p^*\wedge \operatorname{Log} n}. \] We give more explicit formulas, expressed as exact functions of $p$, $q$, $m$, and $n$, for the asymptotic operator norms in the case when the entries $X_{i,j}$ are: Gaussian, Weibullian, log-concave tailed, and log-convex tailed. In the range $1\le q\le 2\le p$ we provide two-sided bounds under a weaker regularity assumption $(\mathbb{E} X_{1,1}^4)^{1/4}\leq α(\mathbb{E} X_{1,1}^2)^{1/2}$.

description: The solar system contains solids of all sizes, ranging from km-size bodies to nano-sized particles. Nanograins have been detected in situ in the Earth's atmosphere, near cometary and giant planet environments, and more recently in the solar wind at 1 AU. These latter nano grains are thought to be formed in the inner solar system dust cloud, mainly through collisional break-up of larger grains and are then picked-up and accelerated by the magnetized solar wind because of their large charge-to-mass ratio. In the present paper, we analyze the low frequency bursty noise identified in the Cassini radio and plasma wave data during the spacecraft cruise phase inside Jupiter's orbit. The magnitude, spectral shape and waveform of this broadband noise is consistent with the signature of nano particles impinging at nearby the solar wind speed on the spacecraft surface. Nanoparticles were observed whenever the radio instrument was turned on and able to detect them, at different heliocentric distances between Earth and Jupiter, suggesting their ubiquitous presence in the heliosphere. We analyzed the radial dependence of the nano dust flux with heliospheric distance and found that it is consistent with the dynamics of nano dust originating from the inner heliosphere and picked-up by the solar wind. The contribution of the nano dust produced in asteroid belt appears to be negligible compared to the trapping region in the inner heliosphere. In contrast, further out, nano dust are mainly produced by the volcanism of active moons such as Io and Enceladus.

Digital Feminist Activism & The Need for Male Allies: Assessing Barriers to Male Participation in the Modern-Day Women’s Movement
Creators: name: Nicolla, Sydney
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Typically, women instigate and drive participation in digital feminist activism, but research has suggested that male activists could play a valuable role as allies for the digital women’s movement. Social media reduce some traditional barriers to activism – time, financial resources – and force us to consider social and emotional factors that may interfere with outward male support for feminism. Results of a U.S. based digital survey demonstrated the following among men who have yet to participate in digital feminist activism (DFA): (1) support from and characteristics of those in their social networks may play an important role in their willingness to engage with DFA in the future; (2) there is still a disconnect between support for feminism and feminist identification, which may affect willingness to participate in DFA; and (3) strong masculine gender identity may correspond to higher willingness to support abstract, but lower willingness to support concrete, feminist objectives.

Pre-transition effects mediate forces of assembly between transmembrane proteins

description: We present a mechanism for a generic and powerful force of assembly and mobility for transmembrane proteins in lipid bilayers. This force is a pre-transition (or pre-melting) effect for the first-order transition between ordered and disordered phases in the host membrane. Using large scale molecular simulation, we show that a protein with hydrophobic thickness equal to that of the disordered phase embedded in an ordered bilayer stabilizes a microscopic order-disorder interface, and the stiffness of that interface is finite. When two such proteins approach each other, they assemble because assembly reduces the net interfacial free energy. In analogy with the hydrophobic effect, we refer to this phenomenon as the "orderphobic effect". The effect is mediated by proximity to the order-disorder phase transition and the size and hydrophobic mismatch of the protein. The strength and range of forces arising from the orderphobic effect are significantly larger than those that could arise from membrane elasticity for the membranes we examine.
description: Combined the previously published arXiv papers (arxiv:1506.04298 and arxiv:1506.04310) into the single paper after addressing comments from colleagues. The first order nature of the order-disorder phase transition is included in this paper. The title is altered to accommodate the changes in the paper

description: The efficiency of laser-cooling relies on the existence of an almost closed optical-transition cycle in the energy spectrum of the considered species. In this respect rare-earth elements exhibit many transitions which are likely to induce noticeable leaks from the cooling cycle. In this work, to determine whether laser-cooling of singly-ionized erbium Er$^+$ is feasible, we have performed accurate electronic-structure calculations of energies and spontaneous-emission Einstein coefficients of Er$^+$, using a combination of \textit{ab initio} and least-square-fitting techniques. We identify five weak closed transitions suitable for laser-cooling, the broadest of which is in the kilohertz range. For the strongest transitions, by simulating the cascade dynamics of spontaneous emission, we show that repumping is necessary, and we discuss possible repumping schemes. We expect our detailed study on Er$^+$ to give a good insight into laser-cooling of neighboring ions like Dy$^+$.

Model Supply Chain Poisoning: Backdooring Pre-trained Models via Embedding Indistinguishability

description: Pre-trained models (PTMs) are widely adopted across various downstream tasks in the machine learning supply chain. Adopting untrustworthy PTMs introduces significant security risks, where adversaries can poison the model supply chain by embedding hidden malicious behaviors (backdoors) into PTMs. However, existing backdoor attacks to PTMs can only achieve partially task-agnostic and the embedded backdoors are easily erased during the fine-tuning process. This makes it challenging for the backdoors to persist and propagate through the supply chain. In this paper, we propose a novel and severer backdoor attack, TransTroj, which enables the backdoors embedded in PTMs to efficiently transfer in the model supply chain. In particular, we first formalize this attack as an indistinguishability problem between poisoned and clean samples in the embedding space. We decompose embedding indistinguishability into pre- and post-indistinguishability, representing the similarity of the poisoned and reference embeddings before and after the attack. Then, we propose a two-stage optimization that separately optimizes triggers and victim PTMs to achieve embedding indistinguishability. We evaluate TransTroj on four PTMs and six downstream tasks. Experimental results show that our method significantly outperforms SOTA task-agnostic backdoor attacks -- achieving nearly 100% attack success rate on most downstream tasks -- and demonstrates robustness under various system settings. Our findings underscore the urgent need to secure the model supply chain against such transferable backdoor attacks. The code is available at https://github.com/haowang-cqu/TransTroj .
