description: Background : Anti-TNF have transformed the approach of chronic inflammatory rheumatism. Although the therapy can be highly effective, anti TNF are associated with an increased risk of opportunistic tuberculosis infections. Laryngeal tuberculosis is rare and it’s often secondary to another localization, particularly pulmonary. Under anti-TNF, its development is unusual [1-2-3]. Case presentation : We report the original case of bifocal tuberculosis: laryngeal and pulmonary revealed by laryngeal involvement in a 41-year-old patient with axial spondylitis treated with Adalimumab. Conclusion : The interest of this presentation is to draw attention to laryngeal tuberculosis when we have atypical signs ORL in a patient under anti TNF for early management.
description: Introduction : Les anti-TNF α ont transformé la prise en charge des rhumatismes inflammatoires chroniques. Bien que le traitement puisse être très efficace, il est associé à un risque accru d’infections notamment tuberculeuse. La tuberculose laryngée est rare. Elle est souvent secondaire à une autre localisation en particulier pulmonaire. Son développement sous anti TNF α est inhabituel [1-2-3]. Observation : Nous rapportons l’observation originale d’une tuberculose bifocale laryngée et pulmonaire révélée par une atteinte laryngée chez un patient de 41 ans atteint de spondyloarthrite axiale traité par Adalimumab. Conclusion : Le risque de tuberculose est élevé au cours du traitement par anti TNF α. Ce diagnostic doit être évoqué devant des signes ORL atypiques.

description: We report experimental demonstration of the feasibility of reaching temperatures below 1 mK using cryogen-free technology. Our prototype system comprises an adiabatic nuclear demagnetisation stage, based on hyperfine-enhanced nuclear magnetic cooling, integrated with a commercial cryogen-free dilution refrigerator and 8 T superconducting magnet. Thermometry was provided by a current-sensing noise thermometer. The minimum temperature achieved at the experimental platform was 600 μK. The platform remained below 1 mK for over 24 hours, indicating a total residual heat-leak into the experimental stage of 5 nW. We discuss straightforward improvements to the design of the current prototype that are expected to lead to enhanced performance. This opens the way to widening the accessibility of temperatures in the microkelvin regime, of potential importance in the application of strongly correlated electron states in nanodevices to quantum computing.

Il risultato è che le meteoriti hanno una temperatura di circa 2 °C superiore a quella ambiente, quindi non possono innescare incendi o ustionarvi se le raccogliete subito a mani nude (non fatelo)
Towards generalization of deep learning in pervasive human motion analysis
Creators: name: Gu, Xiao
Publisher: name: Imperial College London
Year: 2023

description: The analysis of human motion is a crucial component of many digital health applications, including gait analysis, therapeutic training, and daily assistance. In this realm, paradigm shifts have been made by the integration of deep/machine learning with advanced sensing techniques, providing valuable insights into human health conditions through pervasive sensing informatics. However, the success of existing approaches is mostly driven by statistical fitting between input data and given labels, relying on conventional supervised learning methodologies that assume well-balanced and clean datasets with similar distributions between training and testing data. Unfortunately, this assumption rarely holds true for sensing informatics collected in real-world healthcare applications, resulting in poor generalization capabilities. This PhD thesis investigates the limitations of existing deep learning approaches regarding pervasive human motion analysis. First of all, the impact of sensor position heterogeneity as well as the absence of ground truth data for quantitative markerless movement measurement, based on mobile depth cameras, is explored. To tackle these challenges, a self-supervised framework is proposed to leverage synthetic human models and it successfully addresses the heterogeneity between both sensor positions and real-synthetic domains. Furthermore, for movement disorder detection, this thesis examines the impact of the noise as well as individual differences with wearable/ambient sensor data. A cascaded disentangled representation learning framework is proposed to extract clean and clinically meaningful representations from raw sensor data, for cross-subject generalization in abnormal gait recognition. In addition, this thesis investigates two different paradigms for movement intention recognition, egocentric camera based action anticipation and EEG based motor imagery classification. The former work delves into the co-occurrence issue of the cross-subject heterogeneity and class imbalance problem associated with real-world sensor data in the specific egocentric action anticipation task. Several key strategies are proposed to learn unbiased and meaningful representations across different subjects and classes. On the other hand, the issue of data/feature dimensionality heterogeneity with sensor data in motor imagery EEG classification is identified and a novel learning framework is proposed to address this. The proposed framework is targeted at the data-dimensionality variations, and subsequently, implicitly promotes the generalization capability when aggregating data from multiple datasets with heterogeneous dimensions.

description: We propose a novel approach to translate unpaired contrast computed tomography (CT) scans to non-contrast CT scans and the other way around. Solving this task has two important applications: (i) to automatically generate contrast CT scans for patients for whom injecting contrast substance is not an option, and (ii) to enhance the alignment between contrast and non-contrast CT by reducing the differences induced by the contrast substance before registration. Our approach is based on cycle-consistent generative adversarial convolutional transformers, for short, CyTran. Our neural model can be trained on unpaired images, due to the integration of a multi-level cycle-consistency loss. Aside from the standard cycle-consistency loss applied at the image level, we propose to apply additional cycle-consistency losses between intermediate feature representations, which enforces the model to be cycle-consistent at multiple representations levels, leading to superior results. To deal with high-resolution images, we design a hybrid architecture based on convolutional and multi-head attention layers. In addition, we introduce a novel data set, Coltea-Lung-CT-100W, containing 100 3D triphasic lung CT scans (with a total of 37,290 images) collected from 100 female patients (there is one examination per patient). Each scan contains three phases (non-contrast, early portal venous, and late arterial), allowing us to perform experiments to compare our novel approach with state-of-the-art methods for image style transfer. Our empirical results show that CyTran outperforms all competing methods. Moreover, we show that CyTran can be employed as a preliminary step to improve a state-of-the-art medical image alignment method. We release our novel model and data set as open source at https://github.com/ristea/cycle-transformer.

description: Prostate cancer is among the most common cancer in males and its heterogeneity is well known. Its early detection helps making therapeutic decision. There is no standard technique or procedure yet which is full-proof in predicting cancer class. The genomic level changes can be detected in gene expression data and those changes may serve as standard model for any random cancer data for class prediction. Various techniques were implied on prostate cancer data set in order to accurately predict cancer class including machine learning techniques. Huge number of attributes and few number of sample in microarray data leads to poor machine learning, therefore the most challenging part is attribute reduction or non significant gene reduction. In this work we have compared several machine learning techniques for their accuracy in predicting the cancer class. Machine learning is effective when number of attributes (genes) are larger than the number of samples which is rarely possible with gene expression data. Attribute reduction or gene filtering is absolutely required in order to make the data more meaningful as most of the genes do not participate in tumor development and are irrelevant for cancer prediction. Here we have applied combination of statistical techniques such as inter-quartile range and t-test, which has been effective in filtering significant genes and minimizing noise from data. Further we have done a comprehensive evaluation of ten state-of-the-art machine learning techniques for their accuracy in class prediction of prostate cancer. Out of these techniques, Bayes Network out performed with an accuracy of 94.11% followed by Navie Bayes with an accuracy of 91.17%. To cross validate our results, we modified our training dataset in six different way and found that average sensitivity, specificity, precision and accuracy of Bayes Network is highest among all other techniques used.

description: We examine properties of the population of SOHO/STEREO (dwarf) Kreutz sungrazing comets from 2004 to 2013, including the arrival rates, peculiar gaps, and a potential relationship to the spectacular comet C/2011 W3 (Lovejoy). Selection effects, influencing the observed distribution, are largely absent among bright dwarf sungrazers, whose temporal sequence implies the presence of a swarm, with the objects brighter at maximum than apparent magnitude 3 arriving at a peak rate of about 4.6 per year in late 2010, while those brighter than magnitude 2 at a peak rate of about 4.3 per year in early 2011, both a few times the pre-swarm rate. The entire population of SOHO/STEREO Kreutz sungrazers also peaked about one year before the appearance of C/2011 W3. Orbital data show, however, that all bright dwarf sungrazers moved in paths similar to that of comet C/1843 D1, deviating 10 deg or more from the orbit of C/2011 W3 in the angular elements. The evidence from the swarm and the overall elevated arrival rates suggests the existence of a fragmented sizable sungrazer that shortly preceded C/2011 W3 but was independent of it. On the other hand, these findings represent another warning signal that the expected 21st-century cluster of spectacular Kreutz comets is on its way to perihelion, to arrive during the coming decades. It is only in this sense that we find a parallel link between C/2011 W3 and the spikes in the population of SOHO/STEREO Kreutz sungrazers.

description: CERN-LHC. A search is presented for particles that decay producing a large jet multiplicity and invisible particles. The event selection applies a veto on the presence of isolated electrons or muons and additional requirements on the number of $b$-tagged jets and the scalar sum of masses of large-radius jets. Having explored the full ATLAS 2015--2016 dataset of LHC proton--proton collisions at $\sqrt{s}$=13 TeV, which corresponds to 36.1~fb$^{-1}$ of integrated luminosity, no evidence is found for physics beyond the Standard Model.The results are interpreted in the context of simplified models inspired by R-parity-conserving and R-parity-violating supersymmetry, where gluinos are pair-produced. More generic models within the phenomenological minimal supersymmetric Standard Model are also considered.

description: Three critical issues for causal inference that often occur in modern, complicated experiments are interference, treatment nonadherence, and missing outcomes. A great deal of research efforts has been dedicated to developing causal inferential methodologies that address these issues separately. However, methodologies that can address these issues simultaneously are lacking. We propose a Bayesian causal inference methodology to address this gap. Our methodology extends existing causal frameworks and methods, specifically, two-staged randomized experiments and the principal stratification framework. In contrast to existing methods that invoke strong structural assumptions to identify principal causal effects, our Bayesian approach uses flexible distributional models that can accommodate the complexities of interference and missing outcomes, and that ensure that principal causal effects are weakly identifiable. We illustrate our methodology via simulation studies and a re-analysis of real-life data from an evaluation of India's National Health Insurance Program. Our methodology enables us to identify new active causal effects that were not identified in past analyses. Ultimately, our simulation studies and case study demonstrate how our methodology can yield more informative analyses in modern experiments with interference, treatment nonadherence, missing outcomes, and complicated outcome generation mechanisms.

Advances of graph neural networks for 3D shape learning and analysis
Creators: name: Potamias, Rolandos Alexandros
Publisher: name: Imperial College London
Year: 2023

description: In recent years, there has been a surge in the availability of 3D sensors, leading to an exponential increase in the amount of 3D data, paving the way for remarkable advancements in 3D computer vision applications. The advances of deep learning on geometric data with irregular structures, such as meshes and point clouds, have further enhanced the ability to analyze and understand 3D shapes. In this thesis, we explore the usage of geometric deep learning methods in 3D shape analysis. The thesis can be divided into two parts. In the first part, the advancements of non-linear localized mesh convolutions to tackle the limitations of traditional statistical shape modeling methods, such as PCA, to capture fine details and extreme deformations given its linear structure and global structure is shown. In particular, the cases of static and dynamic neural deformable models are explored using a localized mesh convolution operator to generate high fidelity deformable models. Using a large scale dataset of hand scans composed by over 1200 subjects, a fine-grained neural hand model is constructed that is able to outperform current state-of-the-art hand models. To explore the expressive power of graph convolution in dynamic morphable models, a 4D generative model is proposed that is able to manipulate 3D faces and generate dynamic expressions fully customized by the user. Both models achieve state-of-the-art performance that outperforms traditional PCA deformable models. However, dealing with high-fidelity models poses several challenges, especially when it comes to processing and storage. The enormous amount of points needed to capture the fine-grained features of such models can be computationally expensive and memory-intensive which limits their real-time applications. In the second part of this thesis, two neural based simplification methods are proposed to simplify point clouds and meshes in real-time. Both methods rely on graph neural networks to capture rich local and global topological information of the 3D objects. Initially, a point cloud simplification method is proposed that samples points in an sophisticated matter to preserve the underlying perceptual features of the point cloud. Then, the simplification method is extended to meshes through a graph neural network triangulation module that constructs the faces of the simplified mesh. Through extensive evaluations and comparisons with state-of-the-art baselines, we demonstrate the effectiveness and efficiency of our method in preserving important shape characteristics while significantly reducing the data size.

We find that the paramagnetic fluctuations in an interacting Fermi liquid typically drive the transition first order at zero temperature. We first gain insight from a calculation using second order perturbation theory in the self-energy. This is valid for weak interaction and far from instabilities. We then extend the results to stronger interaction, using the self-consistent fluctuation approximation. Experimental signatures are given in the light of these results.

description: The Galactic transient black hole candidate GX 339-4 is a very interesting object to study as it showed both complete and failed types of outbursts. We studied both spectral and temporal properties of the 2017-18 outburst of the source using archival data of NICER and AstroSat instruments. This 2017-18 outburst is found to be failed in nature, as during the entire period of the outburst, the source was only in the hard spectral state. Source spectra were highly dominated with the non-thermal fluxes. When we tried to fit spectra with phenomenological models, most of the spectra were fitted with only the powerlaw model, and only six spectra required disk black body plus powerlaw models. While fitting spectra with the physical two-component advective flow (TCAF) model, we observed that the flow was highly dominated by the sub-Keplerian halo rate. The presence of stronger shock at a larger radius from the black hole was also observed during the rising and declining phases of the outburst. A prominent signature of $0.31$~Hz QPO is observed with its four harmonics. Mass of the black hole was also estimated from our spectral analysis with the TCAF model as $10.76^{+0.77}_{-1.07}~M_\odot$.

description: Due to its ability to tolerate high channel loss, decoy-state quantum key distribution (QKD) has been one of the main focuses within the QKD community. Notably, several experimental groups have demonstrated that it is secure and feasible under real-world conditions. Crucially, however, the security and feasibility claims made by most of these experiments were obtained under the assumption that the eavesdropper is restricted to particular types of attacks or that the finite-key effects are neglected. Unfortunately, such assumptions are not possible to guarantee in practice. In this work, we provide concise and tight finite-key security bounds for practical decoy-state QKD that are valid against general attacks.

description: We developed a novel method based on the Fourier analysis of protein molecular surfaces to speed up the analysis of the vast structural data generated in the post-genomic era. This method computes the power spectrum of surfaces of the molecular electrostatic potential, whose three-dimensional coordinates have been either experimentally or theoretically determined. Thus we achieve a reduction of the initial three-dimensional information on the molecular surface to the one-dimensional information on pairs of points at a fixed scale apart. Consequently, the similarity search in our method is computationally less demanding and significantly faster than shape comparison methods. As proof of principle, we applied our method to a training set of viral proteins that are involved in major diseases such as Hepatitis C, Dengue fever, Yellow fever, Bovine viral diarrhea and West Nile fever. The training set contains proteins of four different protein families, as well as a mammalian representative enzyme. We found that the power spectrum successfully assigns a unique signature to each protein included in our training set, thus providing a direct probe of functional similarity among proteins. The results agree with established biological data from conventional structural biochemistry analyses.

description: CERN-LHC. A search is presented for particles that decay producing a large jet multiplicity and invisible particles. The event selection applies a veto on the presence of isolated electrons or muons and additional requirements on the number of $b$-tagged jets and the scalar sum of masses of large-radius jets. Having explored the full ATLAS 2015--2016 dataset of LHC proton--proton collisions at $\sqrt{s}$=13 TeV, which corresponds to 36.1~fb$^{-1}$ of integrated luminosity, no evidence is found for physics beyond the Standard Model.The results are interpreted in the context of simplified models inspired by R-parity-conserving and R-parity-violating supersymmetry, where gluinos are pair-produced. More generic models within the phenomenological minimal supersymmetric Standard Model are also considered.

description: Weak gravitational lensing observations are a key science driver for the NASA Wide Field Infrared Survey Telescope (WFIRST). To validate the performance of the WFIRST infrared detectors, we have performed a laboratory emulation of weak gravitational lensing measurements. Our experiments used a custom precision projector system to image a target mask composed of a grid of pinholes, emulating stellar point sources, onto a 1.7 micron cut-off Teledyne HgCdTe/H2RG detector. We used a 880nm LED illumination source and f/22 pupil stop to produce undersampled point spread functions similar to those expected from WFIRST. We also emulated the WFIRST image reconstruction strategy, using the IMage COMbination (IMCOM) algorithm to derive oversampled images from dithered, undersampled input images. We created shear maps for this data and computed shear correlation functions to mimic a real weak lensing analysis. After removing only 2nd order polynomial fits to the shear maps, we found that the correlation functions could be reduced to O(10^-6). This places a conservative upper limit on the detector-induced bias to the correlation function (under our test conditions). This bias is two orders of magnitude lower than the expected weak lensing signal. Restricted to scales relevant to dark energy analyses (sky separations > 0.5 arcmin), the bias is O(10^-7): comparable to the requirement for future weak lensing missions to avoid biasing cosmological parameter estimates. Our experiment will need to be upgraded and repeated under different configurations to fully characterize the shape measurement performance of WFIRST IR detectors.

description: In this paper we use the model of extragalactic background light to investigate the factors that have influence on the confusion noise. It was shown that (1) Large-Scale Structure of the Universe is an important factor; (2) gravitational lensing does not have a significant effect on the confusion noise; (3) lower redshift limit of objects that contribute to the confusion noise does not depend on the wavelength and is about $z_{min}\sim 0.5-0.6$, while upper redshift limit gradually changes from $\sim4$ to $\sim3$ with the increase of wavelength from 70$μm$ up to 2000$μm$; (4) at rather short wavelengths ($\simeq70μm$) galaxies with luminosities in the range $10^7L_\odot$ -- $10^9L_\odot$ give the most contribution to the confusion noise, while at larger wavelengths (650-2000$μm$) their luminosities are greater than $L\geq10^{10}L_\odot$; (5) contribution from objects with different color characteristics is considered; (6) the variability of the extragalactic background on the timescale from 1 day to 1 year is noticeable at short wavelengths (70--350$μm$) and manifests at fluxes ${}^<_\sim$ 1~mJy.

description: Using a new uniform sample of 824 solar and late-type stars with measured X-ray luminosities and rotation periods we have studied the relationship between rotation and stellar activity that is believed to be a probe of the underlying stellar dynamo. Using an unbiased subset of the sample we calculate the power law slope of the unsaturated regime of the activity -- rotation relationship as $L_X/L_{bol}\propto Ro^β$, where $β=-2.70\pm0.13$. This is inconsistent with the canonical $β= -2$ slope to a confidence of 5$σ$ and argues for an interface-type dynamo. We map out three regimes of coronal emission as a function of stellar mass and age, using the empirical saturation threshold and theoretical super-saturation thresholds. We find that the empirical saturation timescale is well correlated with the time at which stars transition from the rapidly rotating convective sequence to the slowly rotating interface sequence in stellar spin-down models. This may be hinting at fundamental changes in the underlying stellar dynamo or internal structure. We also present the first discovery of an X-ray unsaturated, fully convective M star, which may be hinting at an underlying rotation - activity relationship in fully convective stars hitherto not observed. Finally we present early results from a blind search for stellar X-ray cycles that can place valuable constraints on the underlying ubiquity of solar-like activity cycles.

description: Cosmic superstring loops within the galaxy microlens background point sources lying close to the observer-string line of sight. For suitable alignments, multiple paths coexist and the (achromatic) flux enhancement is a factor of two. We explore this unique type of lensing by numerically solving for geodesics that extend from source to observer as they pass near an oscillating string. We characterize the duration of the flux doubling and the scale of the image splitting. We probe and confirm the existence of a variety of fundamental effects predicted from previous analyses of the static infinite straight string: the deficit angle, the Kaiser-Stebbins effect, and the scale of the impact parameter required to produce microlensing. Our quantitative results for dynamical loops vary by O(1) factors with respect to estimates based on infinite straight strings for a given impact parameter. A number of new features are identified in the computed microlensing solutions. Our results suggest that optical microlensing can offer a new and potentially powerful methodology for searches for superstring loop relics of the inflationary era.

description: In this paper, we propose Regional Energy Efficient Cluster Heads based on Maximum Energy (REECH-ME) Routing Protocol for Wireless Sensor Networks (WSNs) . The main purpose of this protocol is to improve the network lifetime and particularly the stability period of the network. In REECH-ME, the node with the maximum energy in a region becomes Cluster Head (CH) of that region for that particular round and the number of the cluster heads in each round remains the same. Our technique outperforms LEACH which uses probabilistic approach for the selection of CHs. We also implement the Uniform Random Distribution Model to find the packet drop to make this protocol more practical. We also calculate the confidence interval of all our results which helps us to visualize the possible deviation of our graphs from the mean value.
