title: Identifying Envirogenomic Signatures for Predicting the Clinical Outcomes of Crohn's Disease
Creators: name: Nasir, Bushra Farah
Publisher: name: Griffith University
Year: 2013
Subjects: subject: Crohn's disease
subject: Genetic susceptibility to Crohn's Disease.

description: A complex interplay between genetic susceptibility, environmental factors and clinical indicators seem to cause the development of Crohn’s disease (CD). Few disorders in clinical medicine are associated with as much chronic morbidity as CD. Genetic factors are the predetermined cause, whereas non-genetic factors seem to further trigger the development of CD. From epidemiological data, based on concordance statistics in family studies, via linkage analysis to Genome Wide Association Studies (GWAS) and Whole Genome Analysis (WGA), robust evidence have been gathered, implicating distinct genomic loci involved in genetic susceptibility to CD. Most recently, a meta-analysis has been able to implicate 71 distinct genomic loci that seem to be associated with CD development. A study published in the American Journal of Human Genetics has also recently identified more than 200 genes associated with CD, which is more than what have been found for any other disease so far. Monozygotic twins show approximately 50-60% disease concordance, with much lower rates in dizygotic twins (~10%), highlighting the role of both environmental and genetic components in the development of CD.

description: This paper studies vortex-lattice phases of rapidly rotating superfluid ^3He based on the Ginzburg-Landau free-energy functional. To identify stable phases in the p-Omega plane (p: pressure; Omega: angular velocity), the functional is minimized with the Landau-level expansion method using up to 3000 Landau levels. This system can sustain various exotic vortices by either (i) shifting vortex cores among different components or (ii) filling in cores with components not used in the bulk. In addition, the phase near the upper critical angular velocity Omega_{c2} is neither the A nor B phases, but the polar state with the smallest superfluid density as already shown by Schopohl. Thus, multiple phases are anticipated to exist in the p-Omega plane. Six different phases are found in the present calculation performed over 0.0001 Omega_{c2} <= Omega <= Omega_{c2}, where Omega_{c2} is of order (1- T/T_c) times 10^{7} rad/s. It is shown that the double-core vortex experimentally found in the B phase originates from the conventional hexagonal lattice of the polar state near Omega_{c2} via (i) a phase composed of interpenetrating polar and Scharnberg-Klemm sublattices; (ii) the A-phase mixed-twist lattice with polar cores; (iii) the normal-core lattice found in the isolated-vortex calculation by Ohmi, Tsuneto, and Fujita; and (iv) the A-phase-core vortex discovered in another isolated-vortex calculation by Salomaa and Volovik. It is predicted that the double-core vortex will disappear completely in the experimental p-T phase diagram to be replaced by the A-phase-core vortex for Omega >~ 10^{3} ~ 10^{4} rad/s. C programs to minimize a single-component Ginzburg-Landau functional are available at {http://phys.sci.hokudai.ac.jp/~kita/index-e.html}.

Subjects: subject: Electronic banking, Vietnam
subject: Electronic banking, Customer trust

description: Electronic banking services have gained increased popularity around the world; however in Vietnam these services have put just their first footsteps in the beginning of 2005. Electronic banking is an alternative means of offering customers expedited and self-controlled transactions using the Internet as the medium for the transaction. Nowadays, banks use electronic banking services as a powerful “value added” channel to attract and retain new customers. This research examines the critical factors affecting customers’ trust in electronic banking in Vietnam. The analysis is carried out by answering three research questions: Does customers’ trust in electronic banking affect their intention to use electronic banking in Vietnam? What are the key factors affecting customers’ trust in using electronic banking and subsequently, their intention to use electronic banking in Vietnam? How can banks use these factors to foster customers’ trust in electronic banking? These questions often confront researchers as well as bank managers and policy makers.

description: Background Thermophilic Campylobacter species are a major cause of bacterial foodborne diarrhoea in humans worldwide. Poultry and their products are the predominant source for human campylobacteriosis. Resistance of Campylobacter to antibiotics is increasing worldwide, but little is known about the antibiotic resistance in Campylobacter isolated from chicken in Kenya. In this study, 35 suspected Campylobacter strains isolated from faeces and cloacal swabs of chicken were tested for their susceptibility to seven antibiotics using a broth microdilution assay and molecular biological investigations. Results Overall, DNA of thermophilic Campylobacter was identified in 53 samples by PCR (34 C. jejuni, 18 C. coli and one mix of both species) but only 35 Campylobacter isolates (31 C. jejuni and 4 C. coli) could be re-cultivated after transportation to Germany. Isolates were tested for their susceptibility to antibiotics using a broth microdilution assay. Additionally, molecular biological detection of antibiotic resistance genes was carried out. C. jejuni isolates showed a high rate of resistance to nalidixic acid, tetracycline and ciprofloxacin of 77.4, 71.0 and 71.0 %, respectively. Low resistance (25.8 %) was detected for gentamicin and chloramphenicol. Multidrug resistance in C. jejuni could be detected in 19 (61.3 %) isolates. Resistance pattern of C. coli isolates was comparable. Resistance to ciprofloxacin was confirmed by MAMA–PCR and PCR–RFLP in all phenotypically resistant isolates. The tet(O) gene was detected only in 54.5 % of tetracycline resistant C. jejuni isolates. The tet(A) gene, which is also responsible for tetracycline resistance, was found in 90.3 % of C. jejuni and in all C. coli isolates. Thirteen phenotypically erythromycin-resistant isolates could not be characterised by using PCR–RFLP and MAMA–PCR. Conclusions To the best of our knowledge, this study is the first report about resistance to antibiotics in thermophilic Campylobacter originating from chicken in Kenya. Campylobacter spp. show a high level of resistance to ciprofloxacin, nalidixic acid and tetracycline but also a remarkable one to chloramphenicol and gentamicin and they are multidrug resistant. Resistance to antibiotics is a global public health concern. In Kenya, resistance surveillance needs further attention in the future. Efforts to establish at least a National Laboratory with facilities for performing phenotypic and genotypic characterization of thermophilic Campylobacter is highly recommended.

description: The rapid electrochemical determination of Aceclofenac (ACF) has been employed by cyclic voltammetry (CV), differential pulse voltammetry (DPV) using developed OH-functionalised multiwalled carbon nanotube carbon paste electrode (OH-MWCNT/CPE). Modified electrode was characterised by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX), X-ray diffraction spectroscopy (XRD), electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The ACF exhibits two oxidation peaks at +0.4 V, +0.66 V and one reduction peak at +0.3 V. The active surface area of the bare carbon paste electrode (BCPE) and modified electrode have been characterised by using K3[Fe(CN)6] solution containing 0.1 M KCl. In DPV mode, variation of ACF gave the limit of detection (LOD = 3s/m) 0.246 Î¼M over the concentration range 1.0 to 190.0 μM (R2 = 0.9994). The developed electrode has good stability, reproducibility and could be successfully validated for the detection of ACF in pharmaceutical samples and biological fluids.

description: This qualitative case study sought to expand what is known about training methods that improve interpersonal communication skills for mid-level leaders in corporate settings. It looked at a training methodology, Behaviour Analysis (BA, Rackham & Morgan, 1977) conducted in the context of a year-long leadership development program in a biopharmaceutical company in the United States. Interviews with 16 program participants, and post-program survey data from 83 participants across 5 years, responded to three research questions: 1. How, and in what ways, did mid-level leaders perceive the interplay between thinking about how to communicate effectively and behaving in an interpersonally effective way? (perception) 2. How did mid-level leaders apply BA post-program? (application) 3. What were the reported perceptions of mid-level leaders about a relationship between BA and perspective transformation? (meaning) The researcher had unique access to and history with the client as a facilitator and member of the program design team. A qualitative case study approach was appropriate, given the consistent program content and profiles of participants year over year as well as the availability of additional program documents for analysis. Data insights were varied and clustered by cohort. Findings were interpreted using two theoretical frames: (a) Mezirow’s (1978, 2003) work with perspective transformation, and (b) the study’s conceptual framework, based on Argyris and Schön’s (1974) seminal work on action science and single-/double-loop learning. Key findings included: (a) the element of time on learning to balance advocacy and inquiry; (b) BA acting as a disorienting dilemma and menu card for expanded communication strategies; and (c) the placement of the disorienting dilemma in the process of perspective transformation. Four conclusions were drawn: 1. Making a shift in communication skills to balance advocacy and inquiry is additive and transformative. 2. Group and/or peer learning is an important component for increasing self-awareness in corporate L&D programs. 3. Disorienting dilemmas can be engineered and are valuable for bringing unconscious behavior patterns to consciousness for skill-building in a training setting. 4. Time and reflection play critical roles in making conscious connections between espoused theories and theories-in-use to build communication skills.

description: A chain of actors brokers the flow of information through news organizations and transforms local realities into international journalism. “Fixers” are a crucial intermediary link between foreign reporters and local sources, translating, arranging logistics and interviews, and otherwise assisting reporters in gaining access and interpreting events. Fixers’ social networks and management of exchange between reporters and sources, this study argues, significantly shape the news. Brokers’ moral worlds, constituted by both norms of behavior toward brokers and norms that shape the behaviors of brokers themselves, are the focus of particular attention. How do news organizations, client journalists, and local news sources and power holders treat fixers? How do fixers navigate the uneven moral terrain created by conflicting expectations toward them? And how do their strategies for managing clients and sources shape the production of knowledge? This study, based on ethnographic research conducted in Turkey between 2014 and 2016, explains fixers’ mediations and their effects on the news. Empirical chapters provide composite narratives of fixers to illustrate both variation in mediating practices and typical career trajectories, followed by theoretical discussions. The production of international news, I argue, cannot be properly understood without reference to the national and local politics and media worlds that affect who becomes a fixer and what they use fixing to accomplish. Based on these contexts, some see fixing as an opportunity to gain recognition, as an apprenticeship toward a career in global journalism, or as a way to expand their social world; others see fixing as a way to remain anonymous while utilizing journalistic expertise they have developed, as a relatively safe form of activism in non-democratic political systems, or a step toward claiming refugee status. Patterns in who becomes a fixer and why affect the selection of “newsworthy” sources and events, the way local realities are transformed into information fed to client reporters, and the organizational structure of the foreign press corps. Fixers have difficulty, and are socialized to avoid, challenging overarching and preexisting meta-narratives, or frames, that foreign news organizations apply to Turkey and Syria. Nonetheless, they make use of “wiggle room” afforded them through the process of abstraction of local complexities into overarching narrative frames to shape international news in ways that are significant at the local level. This study offers insights not only into the production of international knowledge about Turkey and Syria, but also into the process of brokerage, a universal phenomenon in all contexts involving coordination of action and sharing of knowledge across social difference.

description: The multi-tracer technique employs a ratio of densities of two differently biased galaxy samples that trace the same underlying matter density field, and was proposed to alleviate the cosmic variance problem. Here we propose a novel application of this approach, applying it to two different tracers one of which is the 21-cm signal of neutral hydrogen from the epochs of reionization and comic dawn. The second tracer is assumed to be a sample of high-redshift galaxies, but the approach can be generalized and applied to other high-redshift tracers. We show that the anisotropy of the ratio of the two density fields can be used to measure the sky-averaged 21-cm signal, probe the spectral energy distribution of radiative sources that drive this signal, and extract large-scale properties of the second tracer, e.g., the galaxy bias. Using simulated 21-cm maps and mock galaxy samples, we find that the method works well for an idealized galaxy survey. However, in the case of a more realistic galaxy survey which only probes highly biased luminous galaxies, the inevitable Poisson noise makes the reconstruction far more challenging. This difficulty can be mitigated with the greater sensitivity of future telescopes along with larger survey volumes.

description: A near-equiatomic FeCoNiCuAl High-entropy alloy (HEA) was produced using laser powder bed fusion (L-PBF) pre-alloy powder. Microstructural characteristics and tribological properties of L-PBF specimens under various volumetric energy densities (VEDs) were investigated in detail. The results showed that the phase of L-PBF specimen consisted of BCC matrix + Cu-rich B2 precipitate. The microstructure of L-PBF specimen largely consisted of columnar grains perpendicular to the melt pool boundary (MPB) direction owing to the epitaxial growth along the temperature gradient. The preferred orientation of the L-PBF specimen was gradually transformed from the order of <001> to <101> as the VED rose. Larger size precipitates re-appeared and wider MPB were formed upon faster remelting and steeper cooling as a result of higher VED. Compared to the components produced by Spark Plasma Sintering, L-PBF specimens presented better wear resistance owing to the ultra-fine substructure and nano-scaled precipitates. In addition, the L-PBF specimen produced with 83 J/mm3
 VED exhibits the highest elastic strain to failure (H/Er

description: Beijing Old City was built hundreds of years ago. The structure of Beijing Old City was not designed for automobiles. And today, Beijing Old City is unable to meet the needs of current traffic conditions. With the increase in car ownership in Beijing, parking is a serious problem of the city, especially for Beijing Old City. Government has established a number of policies and solutions for parking in Beijing Old City. But the result is not satisfactory because government may not fundamentally understand the cause of parking problem in Beijing Old City. By doing a case study of a historical preservation district in Beijing Old City, the paper tries to find out the major problem of parking in the area, and find out the root cause of the problem in the study area. The paper includes a review of literatures that related to parking issues. Based on different literatures, and site observation, I make a hypothesis on major parking problems in the study area. The methodology part introduces how to prove my hypothesis, and explains my data collecting methods. By calculating the usage rate of parking facilities, and combining with parking price analysis, I make a comprehensive conclusion of parking problems in the study area. The paper also includes a data collection methodologies; a discussion on current and future policies of parking regulations in Beijing. And in the end, some possible solutions for parking in the study area are presented.

description: Massive mechanical resonators operating at the quantum scale can enable a large variety of applications in quantum technologies, as well as fundamental tests of quantum theory. Of crucial importance in that direction, is both their integrability into state-of-the-art quantum platforms as well as the ability to prepare them in generic quantum states using well-controlled high-fidelity operations. Here, we propose a scheme for controlling a radio-frequency mechanical resonator at the quantum scale using two superconducting transmon qubits that can be integrated on the same chip. Specifically, we consider two qubits coupled via a capacitor in parallel to a superconducting quantum interference device (SQUID), which has a suspended mechanical beam embedded in one of its arms. Following a theoretical analysis of the quantum system, we find that this configuration, in combination with an in-plane magnetic field, can give rise to a tuneable three-body interaction in the single-photon strong-coupling regime, while enabling suppression of the stray qubit-qubit coupling. Using state-of-the-art parameters and qubit operations at single-excitation levels, we numerically demonstrate the possibility of ground-state cooling as well as high-fidelity preparation of mechanical quantum states and qubit-phonon entanglement, i.e. states having negative Wigner functions and obeying non-classical correlations. Our work significantly extends the quantum control toolbox of radio-frequency mechanical resonators and may serve as a promising architecture for integrating such mechanical elements with transmon-based quantum processors.
Symmetry-breaking instabilities of convection in squares

Year: 1996
Subjects: subject: Dynamical Systems (math.DS)

description: Convection in an infinite fluid layer is often modelled by considering a finite box with periodic boundary conditions in the two horizontal directions. The translational invariance of the problem implies that any solution can be translated horizontally by an arbitrary amount. Some solutions travel, but those solutions that are invariant under reflections in both horizontal directions cannot travel, since motion in any horizontal direction is balanced by an equal and opposite motion elsewhere. Equivariant bifurcation theory allows us to understand the steady and time-dependent ways in which a pattern can travel when a mirror symmetry of the pattern is broken in a bifurcation. Here we study symmetry-breaking instabilities of convection with a square planform. A pitchfork bifurcation leads to squares that travel uniformly, while a Hopf bifurcation leads to a new class of oscillations in which squares drift to and fro but with no net motion of the pattern. Two types of travelling squares are possible after a pitchfork bifurcation, and three or more oscillatory solutions are created in a Hopf bifurcation. One of the three oscillations, alternating pulsating waves, has been observed in recent numerical simulations of convection in the presence of a magnetic field. We also present a low-order model of three-dimensional compressible convection that contains these symmetry-breaking instabilities. Our analysis clarifies the relationship between several types of time-dependent patterns that have been observed in numerical simulations of convection.

description: This paper examines the on-site and off-site impacts in the surrounding neighborhoods imposed by the Beijing 2008 Olympics. It firstly develops discussions about the site selection process before and during the bidding process, then looks into the land use evolution resulted from staging the sport event and its influences on local economics, on-site transportation improvements and reuse of the venues. The conclusion is drawn based upon data retrieved from the Beijing municipal government's database, online articles and news reports, site visit, and interviews with planners and business owners. Recommendations are supposed to shed a light on how the city could have achieved greater benefits to the local residents, and what measures it can take to improve the situation. This paper identifies the benefits and costs to local residents of staging the 2008 Olympics, and thus serving to inform planners of Beijing and of future host cities to balance between the impacts on the whole city and the impacts on the local communities when planning for similar mega-events.

description: Epigenetic mechanisms such as genomic imprinting have a fundamental role in embryo and fetal development. Hence, we here studied expression levels of epigenetic modifiers and imprinted genes in cases of ididopathic spontaneous abortion (SA). Thirty-five placental samples and 35 matched fetal tissues from second trimester SA were analysed; including 16 controls (placental and fetal infections as the known cause of spontaneous abortion) and 19 idiopathic SA cases. Transcript levels of epigenetic regulators and imprinted genes were measured by qRT-PCR and methylation at imprinted genes was studied by bisulfite genomic sequencing and MS-MLPA. Global DNA hydroxymethylation (5-hmC) levels were measured by an ELISA-based assay. We observed an upregulation of TET2 and TET3 in placental samples from idiopathic SA cases; however, no significant difference in global 5-hmC levels was observed. On the contrary, in fetal tissues, TET3 was markedly downregulated in idiopathic SA, showing an opposite trend to that observed in placental tissue. IGF2 and CDKN1C were upregulated and MEST downregulated in placentas from idiopathic SA cases; concordantly, IGF2 was also upregulated in fetal tissues from idiopathic SA cases. Although not reaching statistical significance, an increase in methylation levels of MEST, KvDMR1 and H19 DMRs was observed in idiopathic SA cases, concordantly with the observed changes in expression. Our study reveals, for the first time, deregulation of epigenetic modifiers and imprinted genes in both placental and fetal tissues from idiopathic SA cases in the second trimester of pregnancy, indicating a critical role during pregnancy.

description: We study the Hermitian curvature flow of locally homogeneous non-Kähler metrics on compact complex surfaces. In particular, we characterize the long-time behavior of the solutions to the flow. We also provide the first example of a compact complex non-Kähler manifold admitting a finite time singularity for the Hermitian curvature flow. Finally, we compute the Gromov-Hausdorff limit of immortal solutions after a suitable normalization. Our results follow by a case-by-case analysis of the flow on each complex model geometry.

description: We shall investigate the asymptotic behavior of the extended resolvent R(s) of the Dirac operator as |s| increases to infinity, where s is a real parameter. It will be shown that the norm of R(s), as a bounded operator between two weighted Hilbert spaces of square integrable functions on the 3-dimensional Euclidean space, stays bounded. Also we shall show that R(s) converges 0 strongly as |s| increases to infinity. This result and a result of Yamada [15] are combined to indicate that the extended resolvent of the Dirac operator decays much more slowly than those of Schroedinger operators.

description: Accumulating evidence has indicated important roles played by Signal Transducer and Activator of Transcription (STAT) molecules, STAT1, STAT3 and STAT5 in the abnormal growth of cancer cells. Associated with these malignant changes, many of the STAT-target genes involved in cell growth regulation also become deregulated in cancer cells. One very important oncogene overexpressed in many cancers is MYC whose gene promoter has previously been found to be STAT regulated. Gene reporter assays provide useful tools for studying the roles of cytokines such as interferon (IFN) and their activation of STAT-dependent promoters. The aims of this study were to: 1) establish luciferase reporter vectors for evaluating STAT-mediated gene regulation; 2) investigate the differential DNA binding of STAT1 versus STAT3 and their sequence recognition and relate this to the regulation of key genes involved in malignancy, such as MYC; and 3) investigate the role of STAT5 in the regulation of the MYC promoter, given preliminary data which indicated STAT5 might be directly involved.

To break the black box nature of such models it is important to understand the dynamical features of the input driving time series that are formed in the state space. We propose a framework for rigorous analysis of such state representations in vanishing memory state space models such as echo state networks (ESN). In particular, we consider the state space a temporal feature space and the readout mapping from the state space a kernel machine operating in that feature space. We show that: (1) The usual ESN strategy of randomly generating input-to-state, as well as state coupling leads to shallow memory time series representations, corresponding to cross-correlation operator with fast exponentially decaying coefficients; (2) Imposing symmetry on dynamic coupling yields a constrained dynamic kernel matching the input time series with straightforward exponentially decaying motifs or exponentially decaying motifs of the highest frequency; (3) Simple cycle high-dimensional reservoir topology specified only through two free parameters can implement deep memory dynamic kernels with a rich variety of matching motifs. We quantify richness of feature representations imposed by dynamic kernels and demonstrate that for dynamic kernel associated with cycle reservoir topology, the kernel richness undergoes a phase transition close to the edge of stability.

description: GNAMPTOPELTA HOPPER, 1939
 Gnamptopelta Hopper, 1939: 333. Type-species: Trogus obsidianator Brullé. Original designation.
 Species and distribution. There is one species found in North America (Sime & Wahl 1998).
 Autapomorphies. Apical margin of clypeus concave (#4–1); scutellum conical (#20–2); propodeum with median longitudinal carinae anteriad anterior transverse carina present (#32–0); median longitudinal carinae of T1 apically incomplete (#46–1); S2-3 divided, S4-5 entire (#55–1). Alternate combinations: (1) #s 4–1, 20–2, and 55–1, or (2) #s 4–1, 20–2, 32–0, and 55–1.
 Biology. G. obsidianator is a larval-pupal parasitoid of Sphingidae; it has been reared from Amphion floridensis B.P. Clark attacked as third- and fifth-instars (Sime & Wahl, 1998). The association of male and female G. obsidianator with grapevines (Heinrich 1962, 1977) suggests that this species specializes on Vitaceae-feeding sphingids (of which there are at least 10 species in its range (Hodges 1971)), but the degree of specificity is unknown. Reports of G. obsidianator attacking Papilio polyxenes Fabricius (Papilionidae) and Pyrrharctia isabella (J.E. Smith) (Arctiidae) (Weed, 1888; Howard, 1889; Bischoff, 1915; Hopper, 1939) are not corroborated by voucher specimens or recent records; we consider them implausible.

description: Photoemission from a single self-organized GaAs/AlGaAs quantum dot (QD) is temporally resolved with picosecond time resolution. The emission spectra consisting of the multiexciton structures are observed to depend on the delay time and the excitation intensity. Quantitative agreement is found between the experimental data and the calculation based on a model which characterizes the successive relaxation of multiexcitons. Through the analysis we can determine the carrier relaxation time as a function of population of photoinjected carriers. Enhancement of the intra-dot carrier relaxation is demonstrated to be due to the carrier-carrier scattering inside a single QD.

description: After decades of commercialization, genetically modified (GM) crops continue to generate controversy. Countries have developed different GM regulatory styles based on their risk frames, institutional arrangements, and participation modes. Our objective was to understand the development of Chile’s unique regulatory style. We reconstructed the use and regulatory evolution of the technology, identified key actors in the controversy, and compared Chile with other approaches. Chile’s style is ambivalent: restricting commercial use to seed-export but permissive in other domains. This approach reflects a market-caution framing of the issue focused on developing a promising agriculture sub-sector. Thus, Chile became a southern seed nursery for the GM industry. Opponents responded by framing their concerns around a basic demand for public information and transparency. Our case illustrates the challenges and relevance of discussing new technologies in emerging democracies. Access to information, early debates and greater transparency are key to evaluate new technologies in these contexts.

description: The proliferation of online communities has created exciting opportunities to study the mechanisms that explain group success. While a growing body of research investigates community success through a single measure -- typically, the number of members -- we argue that there are multiple ways of measuring success. Here, we present a systematic study to understand the relations between these success definitions and test how well they can be predicted based on community properties and behaviors from the earliest period of a community's lifetime. We identify four success measures that are desirable for most communities: (i) growth in the number of members; (ii) retention of members; (iii) long term survival of the community; and (iv) volume of activities within the community. Surprisingly, we find that our measures do not exhibit very high correlations, suggesting that they capture different types of success. Additionally, we find that different success measures are predicted by different attributes of online communities, suggesting that success can be achieved through different behaviors. Our work sheds light on the basic understanding of what success represents in online communities and what predicts it. Our results suggest that success is multi-faceted and cannot be measured nor predicted by a single measurement. This insight has practical implications for the creation of new online communities and the design of platforms that facilitate such communities.

description: Knowledge distillation is effective for producing small, high-performance neural networks for classification, but these small networks are vulnerable to adversarial attacks. This paper studies how adversarial robustness transfers from teacher to student during knowledge distillation. We find that a large amount of robustness may be inherited by the student even when distilled on only clean images. Second, we introduce Adversarially Robust Distillation (ARD) for distilling robustness onto student networks. In addition to producing small models with high test accuracy like conventional distillation, ARD also passes the superior robustness of large networks onto the student. In our experiments, we find that ARD student models decisively outperform adversarially trained networks of identical architecture in terms of robust accuracy, surpassing state-of-the-art methods on standard robustness benchmarks. Finally, we adapt recent fast adversarial training methods to ARD for accelerated robust distillation.
