description: Introduction: Laparo-Endoscopic Single Site (LESS) Surgery represents an evolution in minimally invasive surgery because surgeons forego multiple incisions, hopefully leading to no discernable scar or body image distortion. This study was undertaken to ascertain the value patients assign to “scarless” laparoscopic surgery.

Methods: Before their initial office visit, 604 patients (65% women; age 58 years; BMI 27 kg/m2) were surveyed about their body image utilizing a Likert scale (1=definitely disagree, to 5=definitely agree) and were asked to prioritize factors potentially associated with their impending LESS operation.

Results:  Patients were neutral about their body image when responding to prompts:

In considering LESS surgery relative to conventional laparoscopy, patients were willing to accept “no more risk” (69%), an operation “not longer in duration” (52%), “no additional pain” (67%), a recovery “not longer in duration” (61%), “no greater risk of incisional hernia” (76%), and “no increase in cost” (52%).  In prioritizing possible outcomes achieved with LESS surgery, patients rated (most to least important): risk, pain, operative duration, and cosmetic outcome (i.e., the lack of a scar) independent of BMI and sex; younger patients, however, were willing to undergo operations up to 50% longer if they resulted in no apparent scar (p<0.001).  Patients reported that it would not reduce their attraction to LESS surgery if an additional incision was made on their abdominal wall (86%) or side (83%).

Conclusions: Patients are neutral about their body image prior to proposed LESS surgery and generally do not assign great value to “scarless” laparoscopic surgery.  Several considerations are more important than cosmesis, particularly for older patients: risk, operative duration, pain, recovery time, risk of incisional hernia, and cost; cosmesis is more important in younger patients denoting that ‘some’ patients care very much about cosmesis.  This begs to question: “is there too much emphasis on cosmesis”? Since traditional laparoscopy is well tolerated and meeting patients’ needs, is traditional laparoscopy the end of the road for all but the younger patients?

description: Recently, an extension of the standard four-dimensional scalar conformal action, yielding a second-order field equation that remains conformally invariant, was proposed. In spite of this, the corresponding action is not invariant under conformal transformations and this motivates us to define the notion of non-Noetherian conformal scalar field. In this article, we go further by determining the most general action in four dimensions that gives rise to a non-Noetherian conformal scalar field satisfying a second-order equation. This task is achieved by using the solution to the inverse problem of the calculus of variations. Surprisingly enough, the standard equation is shown to be extended by a non-Noetherian conformal piece involving a nonminimal coupling with a very particular combination of squared curvature terms, which is none other than the one defining the so-called Critical Gravity. We also prove that the most general second-order Euler-Lagrange equation for a conformal scalar field involves additional Noetherian conformal nonminimal couplings defined by an arbitrary function of the Weyl tensor. The recently proposed non-Noetherian conformal extension is recovered as a particular example of this function.

description: Let $k$ be a field with $u$-invariant $\leq2$. Assume further that $k$ is not quadratically closed, $\mathsf{char}(k)\neq 2$ and $|k|\geq 5$. It is known that the covering number of both $\text{SL}_2(k)$ and $\text{PSL}_2(k)$ is three, while their extended covering number is four. In this article, we completely describe the product of two conjugacy classes in $\text{SL}_2(k)$ and $\text{PSL}_2(k)$. Further, we also describe the product of three conjugacy classes (at least two of which are distinct) in $\text{SL}_2(k)$ and $\text{PSL}_2(k)$.

description: We explore the possibility of detecting primordial non-Gaussianity of the local type using weak lensing peak counts. We measure the peak abundance in sets of simulated weak lensing maps corresponding to three models f_NL={0, +100, -100}. Using survey specifications similar to those of Euclid and without assuming any knowledge of the lens and source redshifts, we find the peak functions of the non-Gaussian models with f_NL=+-100 to differ by up to 15% from the Gaussian peak function at the high-mass end. For the assumed survey parameters, the probability of fitting an f_NL=0 peak function to the f_NL=+-100 peak functions is less than 0.1%. Assuming the other cosmological parameters known, f_NL can be measured with an error Δf_NL ~ 13. It is therefore possible that future weak lensing surveys like Euclid and LSST may detect primordial non-Gaussianity from the abundance of peak counts, and provide complementary information to that obtained from the cosmic microwave background.

Genetic dissection of Sclerotinia sclerotiorum biology using forward genetics

Publisher: name: University of British Columbia

description: Diverse plant fungal pathogens that cause worldwide crop losses are understudied due to various technical challenges. With the increasing availability of sequenced whole genomes of these non-model fungi, effective genetic analysis methods are highly desirable. My PhD projects focus on the establishment of a new gene discovery pipeline, which combines a fast forward genetic screening in large scale with high-throughput next-generation sequencing. I applied this pipeline in the notorious soilborne phytopathogen, Sclerotinia sclerotiorum, and identified 32 mutants with various developmental and growth deficiencies. Detailed molecular studies of three melanisation-deficient mutants provide a proof of concept for the effectiveness of our method. Furthermore, using this forward genetic approach, a RAS-GTPase activating protein, SsGAP1, was identified, which plays essential roles in sclerotia formation, compound appressoria production and virulence. To find the responsible RAS-GTPase being activated by SsGAP1 through mutant phenotypes comparison, I knocked down two RAS-GTPases, SsRAS1 and SsRAS2, respectively. My results revealed that both SsRAS1 and SsRAS2 are required for vegetative growth, sclerotia formation, compound appressoria production and virulence. As RNA can move from plant hosts to associating eukaryotic pathogens, trans-species RNAi pathway has been employed for pathogen control through host-induced gene silencing (HIGS). Thereby, I tested whether these RAS signaling genes can be used as HIGS targets to control stem rot caused by S. scleortiorum. Here, when I infiltrated tobacco leaves with Agrobacterium with RNAi constructs targeting SsGAP1 and SsRAS1, I observed reduced virulence. Taken together, my forward genetics gene discovery pipeline in S. sclerotiorum is highly effective in identifying novel HIGS targets to control fungal diseases caused by S. sclerotiorum. As RAS signaling is conserved in eukaryotes, these RAS signaling genes may also have the potential to be used for controlling other fungal diseases in higher plants. Altogether, with the successful identification of these causal genes responsible for the phenotypes of their respective mutants, it is foreseeable that this pipeline can be applied to facilitate efficient in-depth studies of other non-model fungal species and identify more novel HIGS targets against fungal pathogens in the future.
Accretion and Structure of Radiating Disks

description: We studied a steadily accreting, geometrically thick disk model that selfconsistently takes into account selfgravitation of the polytropic gas, its interaction with the radiation and the mass accretion rate. The accreting mass is injected inward in the vicinity of the central $z=0$ plane, where also radiation is assumed to be created. The rest of the disk remains approximately stationary. Only conservation laws are employed and the gas-radiation interaction in the bulk of the disk is described in the thin-gas approximation. We demonstrate that this scheme is numerically viable and yields a structure of the bulk that is influenced by the radiation and (indirectly) by the prescribed mass accretion rate. The obtained disk configurations are typical for environments in Active Galactic Nuclei (AGN), with the central mass of the order of $10^7 M_{\astrosun}$ to $10^8 M_{\astrosun}$, quasi-Keplerian rotation curves, disk masses ranging from about $10^6 M_{\astrosun}$ to $10^7 M_{\astrosun}$, and the luminosity ranging from $10^6 L_{\astrosun}$ to $10^9 L_{\astrosun}$. These luminosities are much lower than the corresponding Eddington limit.

description: We determine star formation rates (SFRs) in a sample of color-selected, star-forming (sBzK) galaxies (K(AB)<21.8) in the Extended Chandra Deep Field - South. To identify and avoid active galactic nuclei, we use X-ray, IRAC color, and IR/radio flux ratio selection methods. Photometric redshift-binned, average flux densities are measured with stacking analyses in Spitzer-MIPS IR, BLAST and APEX/LABOCA submillimeter, VLA and GMRT radio and Chandra X-ray data. We include averages of aperture fluxes in MUSYC UBVRIz'JHK images to determine UV-through-radio spectral energy distributions. We determine the total IR luminosities and compare SFR calibrations from FIR, 24 micron, UV, radio and X-ray wavebands. We find consistency with our best estimator, SFR(IR+UV), to within errors for the preferred radio SFR calibration. Our results imply that 24 micron only and X-ray SFR estimates should be applied to high redshift galaxies with caution. Average IR luminosities are consistent with luminous infrared galaxies. We find SFR(IR+UV) for our stacked sBzKs at median redshifts 1.4, 1.8, and 2.2 to be 55+/-6 (random error), 74+/-8 and 154+/-17 Msun yr^-1 respectively, with additional systematic uncertainty of a factor of ~2.

description: We study the effect of various configurations of vacancies on the magnetic properties of graphene nanoflake (GNF) with screened realistic long-range electron interaction [T. O. Wehling, et. al., Phys. Rev. Lett. 106, 236805 (2011)] within the functional renormalization group approach. In agreement with previous studies, the presence of vacancies in GNF yields to a strong enhancement of spin-density-wave (SDW) correlations. We show however that only some part of the considered configurations of vacancies posses SDW ground state. The probability of a system with a random configuration of vacancies to be in the SDW ground state increases with increase of vacancy concentration. The disorder-averaged sublattice magnetization increases linearly with the concentration of vacancies. The ratio of the sublattice magnetizations at the center and edges of GNF, averaged over various realizations of disorder, depends only weakly on the number of vacancies. The effects of vacancies on the linear conductance and charge properties of GNF are discussed.

description: The boson images of fermion SO(2N+1) Lie operators have been given together with those of SO(2N+2) ones. The SO(2N+1) Lie operators are generators of rotation in the (2N+1)-dimensional Euclidian space (N: number of single-particle states of the fermions). The images of fermion annihilation-creation operators must satisfy the canonical anti-commutation relations, when they operate on a spinor subspace. In the regular representation space we use a boson Hamiltonian with Lagrange multipliers to select out the spinor subspace. Based on these facts, a new description of a fermionic SO(2N+2) top is proposed. From the Heisenberg equations of motions for the boson operators, we get the SO(2N+1) self-consistent field (SCF) Hartree-Bogoliubov (HB) equation for the classical stationary motion of the fermion top. Decomposing an SO(2N+1) matrix into matrices describing paired and unpaired modes of fermions, we obtain a new form of the SO(2N+1) SCF equation with respect to the paired-mode amplitudes. To demonstrate the effectiveness of the new description based on the bosonization theory, the extended HB eigenvalue equation is applied to a superconducting toy-model which consists of a particle-hole plus BCS type interaction. It is solved to reach an interesting and exciting solution which is not found in the traditional HB eigenvalue equation, due to the unpaired-mode effects. To complete the new description, the Lagrange multipliers must be determined in the classical limit. For this aim a quasi anti-commutation-relation approximation is proposed. Only if a certain relation between an SO(2N+1) parameter z and the N is satisfied, unknown parameters k and l in the Lagrange multipliers can be determined withuout any inconcistency.

description: To perform automatic family audio analysis, past studies have collected recordings using phone, video, or audio-only recording devices like LENA, investigated supervised learning methods, and used or fine-tuned general-purpose embeddings learned from large pretrained models. In this study, we advance the audio component of a new infant wearable multi-modal device called LittleBeats (LB) by learning family audio representation via wav2vec 2.0 (W2V2) pertaining. We show given a limited number of labeled LB home recordings, W2V2 pretrained using 1k-hour of unlabeled home recordings outperforms oracle W2V2 pretrained on 960-hour unlabeled LibriSpeech in terms of parent/infant speaker diarization (SD) and vocalization classifications (VC) at home. Extra relevant external unlabeled and labeled data further benefit W2V2 pretraining and fine-tuning. With SpecAug and environmental speech corruptions, we obtain 12% relative gain on SD and moderate boost on VC. Code and model weights are available.

description: The analysis of execution paths (also known as software traces) collected from a given software product can help in a number of areas including software testing, software maintenance and program comprehension. The lack of a scalable matching algorithm operating on detailed execution paths motivates the search for an alternative solution. This paper proposes the use of word entropies for the classification of software traces. Using a well-studied defective software as an example, we investigate the application of both Shannon and extended entropies (Landsberg-Vedral, Rényi and Tsallis) to the classification of traces related to various software defects. Our study shows that using entropy measures for comparisons gives an efficient and scalable method for comparing traces. The three extended entropies, with parameters chosen to emphasize rare events, all perform similarly and are superior to the Shannon entropy.

description: Rosenzweig-Porter (RP) model has garnered much attention in the last decade, as it is a simple analytically tractable model showing both ergodic--nonergodic extended and Anderson localization transitions. Thus, it is a good toy model to understand the Hilbert-space structure of many body localization phenomenon. In our study, we present analytical evidence, supported by exact numerical computations, that demonstrates the controllable tuning of the phase diagram in the RP model by employing on-site potentials with a non-trivial fractal dimension instead of the conventional random disorder. We demonstrate that doing so extends the fractal phase and creates unusual dependence of fractal dimensions of the eigenfunctions. Furthermore, we study the fate of level statistics in such a system and analyze the return probability of a wave packet localized at a single site to provide a dynamical test-bed for our theory.

description: While Monte Carlo event generators like WHIZARD have become indispensable tools in studying the impact of new physics on collider observables over the last decades, the implementation of new models in such packages has remained a rather awkward and error-prone process. Recently, the FeynRules package was introduced which greatly simplifies this process by providing a single unified model format from which model implementations for many different Monte Carlo codes can be derived automatically. In this note, we present an interface which extends FeynRules to provide this functionality also for the WHIZARD package, thus making WHIZARD's strengths and performance easily available to model builders.

K-mer-based data structures and pipelines for sequence mapping and analysis
Creators: name: Goktas, Talha Murathan
Publisher: name: University of British Columbia

description: The exponential growth of genomic data demands progress and research on scalable bioinformatics algorithms. A paradigm to improve computational efficiency in bioinformatics is k-mers. Here we present three works based on the k-mer paradigm that improved the existing methods and opened new possibilities for major applications domains in bioinformatics. LINKS 2.0 is an alignment-free scaffolding tool that brings 3-fold run-time and 5-fold memory optimization to the latest previous version (LINKS v1.8.7). Together with enabling LINKS to process more data with lower computational requirements, this major update also outputs higher- quality scaffolds. Major memory optimization in LINKS 2.0 was obtained by storing k-mers as their 64-bit hash values instead of with ASCII characters. Multi-index Bloom filter (miBF) is a novel associative probabilistic data structure designed for efficiently storing k-mer and spaced seeds. MiBF-mapper discovered the utility of miBF in the long-read mapping domain and demonstrated its competitive accuracy. The mapping with miBF will be a future reference, especially for miBF-based methods. The work on miBF-based global ancestry inference (GAI) proved the scalability of miBF by processing high-coverage data of 208 individuals and promises to increase the accuracy of state-of-art by capturing short insertion and deletion (indel) markers as well as SNPs. We demonstrated high accuracy in continent-level inference and present a promising foundation for developing more accurate, loci-aware ancestry inferences.

description: We have investigated structural, electronic and magnetic properties of H$_2$Pc on Fe$_2$N/Fe using low-energy electron diffraction and soft x-ray absorption spectroscopy/x-ray magnetic circular dichroism. Element specific magnetization curves reveal that the magnetic coupling with H$_2$Pc enhances the perpendicular magnetic anisotropy of Fe$_2$N/Fe at the H$_2$Pc coverage of 1 molecular layer. However, adding two and three molecular layers of H$_2$Pc reverts the shape of magnetization curve back to the initial state before H$_2$Pc deposition. We successfully link appearance and disappearance of the magnetic coupling at the H$_2$Pc-Fe$_2$N/Fe interface with the change of hybridization strength at N sites accompanied by the increase in the H$_2$Pc coverage.

description: Introduction: Laparoscopic Heller myotomy is a first-line treatment for patients with achalasia. The evolution of laparoscopy has allowed laparoscopic Heller myotomy to be undertaken through a single 12mm umbilical incision, Laparo-Endoscopic Single-Site (LESS) surgery. Because it is a “scarless” approach, LESS surgery has the potential to significantly improve cosmetic outcome and patient satisfaction after myotomy. This study was undertaken to compare a single institution’s experience with conventional laparoscopic vs. LESS Heller myotomy.

Methods: With IRB approval, 635 patients have been prospectively followed since 1991 after Heller myotomy; we compared outcomes after conventional laparoscopic vs. LESS myotomy, excluding 45 patients undergoing esophageal diverticulectomy. Patients scored the frequency and severity of their symptoms before and after myotomy using a Likert scale (0=never/not bothersome to 10=always/very bothersome). Patients were queried before myotomy about their greatest postoperative priorities and after myotomy about their scar satisfaction (1=revolting to 10=beautiful). Data are presented as median or median (mean ±SD), where appropriate.

Results: 432 patients underwent conventional laparoscopic myotomy and, more recently, 158 consecutive patients underwent LESS myotomy. 52% of patients were men; median age was 49 years and BMI was 24 kg/m2 for all patients.  Prior to Heller myotomy, patients noted many frequent and severe symptoms (Table). Before LESS myotomy, patients scored safety as their greatest priority, with the appearance and size of the scar and postoperative pain following thereafter. Heller myotomy ameliorated the frequency and severity of symptoms (Table). Relative to conventional laparoscopy, patients who underwent LESS myotomy had similar symptom amelioration without developing new symptoms (e.g., heartburn) (Table), but had a shorter hospital LOS at 1 (2 days ± 3.0) vs. 1 (3 days ± 7) (p<0.05). Median scar satisfaction for patients undergoing LESS myotomy was 10. Patient satisfaction after conventional laparoscopic and LESS Heller myotomy was at 84%.

Conclusions: Heller myotomy, regardless of approach, provides efficacious, satisfactory, and durable palliation of achalasia; symptom resolution and patient satisfaction support its continued application. The LESS approach provides the same salutary benefits as the conventional laparoscopic approach with the additional benefits of shorter hospitalization and improved cosmesis through outstanding scar satisfaction. Ultimately, there is “more gain” associated with LESS Heller myotomy than there is with conventional laparoscopic Heller myotomy, thereby promoting its application.

description: Surgical phase recognition is a challenging and necessary task for the development of context-aware intelligent systems that can support medical personnel for better patient care and effective operating room management. In this paper, we present a surgical phase recognition framework that employs a Multi-Stage Temporal Convolution Network using speech and X-Ray images for the first time. We evaluate our proposed approach using our dataset that comprises 31 port-catheter placement operations and report 82.56 \% frame-wise accuracy with eight surgical phases. Additionally, we investigate the design choices in the temporal model and solutions for the class-imbalance problem. Our experiments demonstrate that speech and X-Ray data can be effectively utilized for surgical phase recognition, providing a foundation for the development of speech assistants in operating rooms of the future.

description: The activity of collections of synchronizing neurons can be represented by weakly coupled nonlinear phase oscillators satisfying Kuramoto's equations. In this article, we build such neural-oscillator models, partly based on neurophysiological evidence, to represent approximately the learning behavior predicted and confirmed in three experiments by well-known stochastic learning models of behavioral stimulus-response theory. We use three Kuramoto oscillators to model a continuum of responses, and we provide detailed numerical simulations and analysis of the three-oscillator Kuramoto problem, including an analysis of the stability points for different coupling conditions. We show that the oscillator simulation data are well-matched to the behavioral data of the three experiments.

description: We study the out-of-equilibrium quantum dynamics of dipolar polarons, i.e., impurities immersed in a dipolar Bose-Einstein condensate, after a quench of the impurity-boson interaction. We show that the dipolar nature of the condensate and of the impurity results in anisotropic relaxation dynamics, in particular, anisotropic dressing of the polaron. More relevantly for cold-atom setups, quench dynamics is strongly affected by the interplay between dipolar anisotropy and trap geometry. Our findings pave the way for simulating impurities in anisotropic media utilizing experiments with dipolar mixtures.

Exploring the feasibility of in situ gene editing on skin for the treatment of genodermatoses

Publisher: name: University of British Columbia

description: Genodermatoses are genetic skin disorders with currently no curative treatment. The fast-paced advancement of gene therapy tools offers a solution for the treatment and cure of genodermatoses. Autosomal Recessive Congenital Ichthyosis (ARCI) is a genetic skin disorder that greatly affects the life-quality of the patient. Here, we hypothesized that the gene editing tool CRISPR-Cas9 can be delivered by lipid nanoparticles into primary human keratinocytes and skin tissue, and genetically edit the epidermis cells. Initially, we screened different formulations of LNPs for physical (size, PDI, zeta potential) and biological (cell viability, gene editing efficacy) characteristics. The first trials suggested DOPE LNPs shows less cytotoxicity (>60%) and higher gene editing efficacy for RNP (14%) and mRNA (15%) approaches. After selecting one formulation in a 2D in vivo approach, we moved to 3D systems: reconstructed skin models and ex vivo excised skin. Also, to improve the penetration of the LNPs into the epidermis, we used 400μm solid microneedles that can create micro-sized openings in the skin and facilitate the permeation of particles. Skin models showed gene editing efficacy of 8-15% for both RNP- and mRNA-loaded LNPs. Similarly, excised human skin indicates gene editing of 9% for RNPloaded and 7% for mRNA-loaded LNPs. To further explore the capacity of CRISPR-loaded LNPs, we tested LNP formulations varying in ionizable lipids. LNPs A-J formulated with different ionizable lipids indicates a significant increase in gene editing efficacy, especially for LNP E (37%) and LNP H (72%), but impaired cell viability (<50%). We also tested the addition of saponins as endosomal escape enhancer, but there were no significant changes in gene editing efficacy. Finally, we tested the use of modified LNPs by adding the cell penetrating peptide Tat. The Tat-LNPs showed an increase in GFP expression when compared to DOPE LNPs, but a lower cell viability. In conclusion, results suggest LNPs loaded with CRISPR-Cas9 components can be delivered in primary human keratinocytes and skin tissue and induce in situ genome editing.

description: A droplet of a classical liquid surrounded by a cold gas placed on a hot substrate is accompanied by unremitting internal circulations, while the droplet remains immobile. Two identical cells with opposite sense of circulation form in the interior due to the thermocapillary effect induced by the gas and substrate temperature difference. Under the same conditions, a droplet composed of an odd viscous liquid exerts a compressive stress on the cell rotating in one sense and tensile on the cell rotating in the opposite sense resulting in a tilted droplet configuration. A sufficiently strong thermal gradient leads the contact angles to overcome hysteresis effects and induces droplet migration.

Development of a Muffler Insertion Loss Flow Rig
Creators: name: Chen, Jonathan
Publisher: name: University of Kentucky Libraries
Year: 2019

description: Abstract:
Mufflers and silencers are commonly used to attenuate noise sources such as internal combustion engines and HVAC systems. Typically, these environments contain mean flow that can affect the acoustic properties of the muffler components and may produce flow generated noise. To characterize the muffler performance, common metrics such as insertion and transmission loss and noise reduction are used in industry. Though transmission loss without flow is often measured and is a relatively simple bench top experiment and useful for model validation purposes, mean flow can significantly affect the muffler performance. There are a few existing and commercial transmission loss rigs that incorporate flow into the measurement procedure. These rigs are useful for model verification including flow but do not predict how the muffler will perform in the system since the source, termination, and pipe lengths significantly impact performance. In this research, the development of an insertion loss test rig is detailed. This testing strategy has the advantage of being simpler, quantifying the self-generated noise due to flow, and taking into account the effect of tailpipe length and a realistic termination. However, the test does not include the actual source and is not as useful for model validation. An electric blower produces the flow and a silencer quiets the flow. Loudspeakers are positioned just downstream of the flow silencer and they are used as the sound source. The low frequency source is a subwoofer installed in a cylindrical enclosure that includes a conical transition from speaker to pipe. Special care is taken to reduce any flow generated noise. Qualification of the system is detailed by comparing the measured transmission loss, noise reduction, and insertion loss to one-dimensional plane wave models. The results demonstrate that the developed rig should be useful as a muffler evaluation tool after a prototype has been constructed. The rig can also be used for transmission loss and noise reduction determination which will prove beneficial for laboratory testing.

description: We present a simple and fast geometric method for modeling data by a union of affine subspaces. The method begins by forming a collection of local best-fit affine subspaces, i.e., subspaces approximating the data in local neighborhoods. The correct sizes of the local neighborhoods are determined automatically by the Jones' $β_2$ numbers (we prove under certain geometric conditions that our method finds the optimal local neighborhoods). The collection of subspaces is further processed by a greedy selection procedure or a spectral method to generate the final model. We discuss applications to tracking-based motion segmentation and clustering of faces under different illuminating conditions. We give extensive experimental evidence demonstrating the state of the art accuracy and speed of the suggested algorithms on these problems and also on synthetic hybrid linear data as well as the MNIST handwritten digits data; and we demonstrate how to use our algorithms for fast determination of the number of affine subspaces.
description: This version adds some clarifications and numerical experiments as well as strengthens the previous theorem. For face experiments, we use here the Extended Yale Face Database B (cropped faces unlike previous version). This database points to a failure mode of our algorithms, but we suggest and successfully test a workaround

description: Many complex and disordered systems fail to reach equilibrium after they have been quenched or perturbed. Instead, they sluggishly relax toward equilibrium at an ever-slowing, history-dependent rate, a process termed physical aging. The microscopic processes underlying the dynamic slow-down during aging and the reason for its similar occurrence in different systems remain poorly understood. Here, we reveal the structural mechanism underlying logarithmic aging in disordered mechanical systems, through experiments in crumpled sheets and simulations of a disordered network of bi-stable elastic elements. We show that under load, the system self-organizes to a metastable state poised on the verge of an instability, where it can remain for long, but finite times. The system's relaxation is intermittent, advancing via rapid sequences of instabilities, grouped into self-similar, aging avalanches. Crucially, the quiescent dwell times between avalanches grow in proportion to the system's age, due to a slow increase of the lowest effective energy barrier, which leads to logarithmic aging.
