description: The so-called 'energy test' is a frequentist technique used in experimental particle physics to decide whether two samples are drawn from the same distribution. Its usage requires a good understanding of the distribution of the test statistic, T, under the null hypothesis. We propose a technique which allows the extreme tails of the T-distribution to be determined more efficiently than possible with present methods. This allows quick evaluation of (for example) 5-sigma confidence intervals that otherwise would have required prohibitively costly computation times or approximations to have been made. Furthermore, we comment on other ways that T computations could be sped up using established results from the statistics community. Beyond two-sample testing, the proposed biased bootstrap method may provide benefit anywhere extreme values are currently obtained with bootstrap sampling.

description: Compositional changes which occur during decomposition of vascular plant tissues have important implications for understanding the biogeochemical cycling of organic matter in aquatic environments. In the following study, long-term changes in the chemical and isotopic composition of six different vascular plant tissues were investigated in litter-bag decomposition experiments which lasted up to four years. Analysis of the major structural polymers and a residual uncharacterized fraction during decomposition revealed the following general stability series from most to least stable: uncharacterized material > lignin ≥ bulk tissue > carbohydrates > cutin. The relative increase in uncharacterized material was substantial in herbaceous tissues and resulted from decreases in initially large, recognizable carbohydrate and cutin fractions. The persistence of lignin through advanced stages of decomposition supported the general application of lignin as a biomarker. However, molecular-level analysis of unique lignin-derived oxidation products showed that the use of lignin as a biomarker can be complicated by the presence of relatively labile ester-bound phenols. To overcome this problem, a new parameter was introduced, Λ₆, which excluded ester-bound phenols and enhanced lignin biomarker potential. Although initially more abundant than lignin, carbohydrates were relatively labile and were largely depleted in highly decomposed tissues. Analysis of neutral sugars indicated that cellulose was the most labile structural carbohydrate. In herbaceous tissues, both glucose and xylose were initially abundant and decomposed more rapidly than other neutral sugars, leading to increased yields of minor sugars, and a general trend towards compositional uniformity of neutral sugars in highly decomposed material. Photooxidation was examined as a potentially important mechanism for selective removal of specific chemical components. Detritus exposed to direct sunlight contained much higher carbohydrate yields, similar levels of cutin acids, and a complete absence of lignin. Changes in stable carbon isotope compositions (ẟ¹³C) of tissues during decomposition reflected changes in chemical composition. Shifts in ẟ¹³C of up to 2‰ were observed in tissues that became enriched in lignin. Exogenous nitrogen comprised 25-69% of the nitrogen in highly decomposed detritus. Shifts in ẟ¹⁵N signatures caused by immobilization of exogenous nitrogen correlated with periods of extensive microbial activity

description: This paper is devoted to the study of generalized subdifferentials of spectral functions over Euclidean Jordan algebras. Spectral functions appear often in optimization problems playing the role of "regularizer", "barrier", "penalty function" and many others. We provide formulae for the regular, approximate and horizon subdifferentials of spectral functions. In addition, under local lower semicontinuity, we also furnish a formula for the Clarke subdifferential, thus extending an earlier result by Baes. As application, we compute the generalized subdifferentials of the function that maps an element to its k-th largest eigenvalue. Furthermore, in connection with recent approaches for nonsmooth optimization, we present a study of the Kurdyka-Lojasiewicz (KL) property for spectral functions and prove a transfer principle for the KL-exponent. In our proofs, we make extensive use of recent tools such as the commutation principle of Ramírez, Seeger and Sossa and majorization principles developed by Gowda.

description: Introduction: Drug checking services for harm reduction and overdose prevention have been implemented in many jurisdictions as a public health intervention in response to the opioid overdose crisis. This study demonstrates the first on-site use of paper spray mass spectrometry for quantitative drug checking to address the limitations of current on-site drug testing technologies. Methods: Paper spray mass spectrometry was used to provide on-site drug checking services at a supervised consumption site in the Downtown Eastside of Vancouver, British Columbia, Canada during a 2-day pilot test in August 2019. The method included the targeted quantitative measurement of 49 drugs and an untargeted full scan to assist in identifying unknown/unexpected components. Results: During the pilot, 113 samples were submitted for analysis, with 88 (78%) containing the client expected substance. Fentanyl was detected in 45 of 59 expected fentanyl samples, and in 50 (44%) samples overall at a median concentration of 3.6% (w/w%). The synthetic precursor of fentanyl, 4-anilino-N-phenethyl-piperidine (4-ANPP), was found in 74.0% of all fentanyl samples at a median concentration of 2.2%, suggesting widespread poor manufacturing practices. Etizolam was detected in 10 submitted samples anticipated to be fentanyl at a median concentration of 2.5%. No clients submitting these samples expected etizolam or a benzodiazepine in their sample. In three instances, it was co-measured with fentanyl, and in seven cases it was detected alone. Discussion and Conclusions. The quantitative capabilities and low detection limits demonstrated by paper spray mass spectrometry offer distinct benefits over existing on-site drug checking methods and harm reduction services.

description: After surgical excision of both malignant and benign lesions, scrotal reconstruction is required.Given the unique anatomy of the scrotum some of the usual reconstructive techniques do not apply or at least not in general. The scrotum's rugated and elastic skin tends to compensate for tissue loss, allowing regeneration even after 60% of the skin has been lost. On the downside, the exposed position of the scrotum and its mobility as well as the need to cover the testes pose a certain barrier to using skin grafts limiting the choices of tissues that can be used for reconstruction. We will review the most common malignant and benign diseases that surgeons will experience in this article, as well as identify a number of reconstructive techniques that will cover the majority of clinical scenarios.

description: This paper considers a class of real-time stochastic optimization problems dependent on an unknown probability distribution. In the considered scenario, data is streaming frequently while trying to reach a decision. Thus, we aim to devise a procedure that incorporates samples (data) of the distribution sequentially and adjusts decisions accordingly. We approach this problem in a distributionally robust optimization framework and propose a novel Online Data Assimilation Algorithm (ONDA Algorithm) for this purpose. This algorithm guarantees out-of-sample performance of decisions with high probability, and gradually improves the quality of the decisions by incorporating the streaming data. We show that the ONDA Algorithm converges under a sufficiently slow data streaming rate, and provide a criteria for its termination after certain number of data have been collected. Simulations illustrate the results.

We use the technique to calculate exact ground-state energies of the model on large lattices. In contrast to many previous studies, we find the model phase separates for all values of J/t. In particular, it is unstable at the hole dopings and interaction strengths at which the model was thought to describe the cuprate superconductors.

Combining Unsupervised and Supervised Learning for Asset Class Failure Prediction in Power Systems

description: In power systems, an asset class is a group of power equipment that has the same function and shares similar electrical or mechanical characteristics. Predicting failures for different asset classes is critical for electric utilities towards developing cost-effective asset management strategies. Previously, physical age based Weibull distribution has been widely used to failure prediction. However, this mathematical model cannot incorporate asset condition data such as inspection or testing results. As a result, the prediction cannot be very specific and accurate for individual assets. To solve this important problem, this paper proposes a novel and comprehensive data-driven approach based on asset condition data: K-means clustering as an unsupervised learning method is used to analyze the inner structure of historical asset condition data and produce the asset conditional ages; logistic regression as a supervised learning method takes in both asset physical ages and conditional ages to classify and predict asset statuses. Furthermore, an index called average aging rate is defined to quantify, track and estimate the relationship between asset physical age and conditional age. This approach was applied to an urban distribution system in West Canada to predict medium-voltage cable failures. Case studies and comparison with standard Weibull distribution are provided. The proposed approach demonstrates superior performance and practicality for predicting asset class failures in power systems.

description: Capsule: Plumage colour of Northern Saw-whet Owls Aegolius acadicus was strongly associated with body condition and may be used to distinguish the highest quality individuals. Relationships between eye colour and body condition were more complex and deserve further study. Aims: We explored the association of colouration with body condition of Northern Saw-whet Owls during their autumnal migration across Pennsylvania, USA from 1999 to 2012. Methods: We used fat and keel scores of female owls to index body condition. Since feathers are laid down during pre-migration moult, we hypothesized that facial white plumage would be more strongly associated with long-term condition (keel scores) whereas eye colour should indicate short-term condition (fat scores). Results: Facial white plumage and eye colour were largely uncorrelated, but were strongly associated with both fat and keel scores. Contrary to our hypothesis, owls with more facial white plumage had both higher fat and keel scores, indicating that facial white was strongly associated with both short- and long-term condition. This appears to be because facial white was highest in individuals most capable of maintaining good condition in both scores (the highest quality owls). Relationships between condition and eye colour were more complex, since owls with highest fat scores but lowest keel scores had lightest eyes, possibly resulting from trade-offs with pigment function and immunocompetence. Our results also demonstrated environmental forcing (cyclic prey availability) of colouration and body condition, although not the relationship between them which remained consistent between years and for different ages. Conclusion: Facial white, but not eye colour, was a robust predictor of short- and long-term body condition, permitting detection of individuals in the best and most consistent condition. Further study of colouration and condition are needed to elucidate the extent of genetic control and environmental factors in feather melanization.

description: The behavior of electrolyte solutions close to a charged surface is studied theoretically. A modified Poisson-Boltzmann equation which takes into account the volume excluded by the ions in addition to the electrostatic interactions is presented. In a formal lattice gas formalism the modified Poisson-Boltzmann equation can be obtained from a mean-field approximation of the partition function. In an alternative phenomenological approach, the same equation can be derived by including the entropy of the solvent molecules in the free energy. In order to visualize the effect of the steric repulsion, a simple case of a single, highly charged, flat surface is discussed. This situation resembles recent adsorption experiments of large ions onto a charged monolayer. A simple criterion for the importance of the steric effects is expressed in terms of the surface charge density and the size of the ions. It is shown that when these effects are important a saturated layer is formed near the surface. A modified Grahame equation relating the ion concentration at the surface to the surface charge density is obtained.

Global weak solutions to a two-dimensional compressible MHD equations of viscous non-resistive fluids

Year: 2018
Subjects: subject: Analysis of PDEs (math.AP)

description: We consider a two-dimensional MHD model describing the evolution of viscous, compressible and electrically conducting fluids under the action of vertical magnetic field without resistivity. Existence of global weak solutions is established for any adiabatic exponent γ>1. Inspired by the approximate scheme proposed in [15], we consider a two-level approximate system with artificial diffusion and pressure term. At the first level, we prove global well-posedness of the regularized system and establish uniform-in-εestimates to the regular solutions. At the second level, we show global existence of weak solutions to the system with artificial pressure by sending εto 0 and deriving uniform-in-δestimates. Then global weak solution to the original system is constructed by vanishing δ. The key issue in the limit passage is the strong convergence of approximate sequence of the density and magnetic field. This is accomplished by following the technique developed in [15, 26] and using the new technique of variable reduction developed by Vasseur et al. [33] in order to handle the cross terms.

description: Background: Neoadjuvant chemoradiation with delayed surgery (CRT-DS) and short-course radiotherapy with immediate surgery (SCRT-IS) are two commonly used treatment strategies for rectal cancer. However, the optimal treatment strategy for patients with intermediate-risk rectal cancer remains a discussion. This study compares quality of life (QOL) between SCRT-IS and CRT-DS from diagnosis until 24 months after treatment. Methods: In a prospective colorectal cancer cohort, rectal cancer patients with clinical stage T2-3N0-2M0 undergoing SCRT-IS or CRT-DS between 2013 and 2017 were identified. QOL was assessed using EORTC-C30 and EORTC-CR29 questionnaires before the start of neoadjuvant treatment (baseline) and at 3, 6, 12, 18 and 24 months after. Patients were 1:1 matched using propensity sore matching. Between- and within-group differences in QOL domains were analyzed with linear mixed-effects models. Symptoms and sexual interest at 12 and 24 months were compared using logistic regression models. Results: 156 of 225 patients (69%) remained after matching. The CRT-DS group reported poorer emotional functioning at 3, 6, 12, 18 and 24 months (mean difference with SCRT-IS: −9.4, −12.1, −7.3, −8.0 and −7.9 respectively), and poorer global health, physical-, role-, social- and cognitive functioning at 6 months (mean difference with SCRT-IS: −9.1, −9.8, −14.0, −9.2 and −12.6, respectively). Besides emotional functioning, all QOL domains were comparable at 12, 18 and 24 months. Within-group changes showed a significant improvement of emotional functioning after baseline in the SCRT-IS group, whereas only a minor improvement was observed in the CRT-DS group. Symptoms and sexual interest in male patients at 12 and 24 months were comparable between the groups. Conclusions: In rectal cancer patients, CRT-DS may induce a stronger decline in short-term QOL than SCRT-IS. From 12 months onwards, QOL domains, symptoms and sexual interest in male patients were comparable between the groups. However, emotional functioning remained higher after SCRT-IS than after CRT-DS.

In situations where the Heisenberg scaling is achievable, we provide a semidefinite program to identify the optimal quantum error correcting (QEC) protocol that yields the best estimation precision. We overcome the technical challenges associated with potential incompatibility of the measurement optimally extracting information on different parameters by utilizing the Holevo Cramér-Rao (HCR) bound for pure states. We provide examples of significant advantages offered by our joint-QEC protocols, that sense all the parameters utilizing a single error-corrected subspace, over separate-QEC protocols where each parameter is effectively sensed in a separate subspace.

description: Invasive non-indigenous species (NIS) are a threat to marine biodiversity and marine reliant industries. Recreational vessels are recognised as an important vector of NIS translocation, particularly domestically. This paper reports on a novel application of multilevel modelling and multiple imputation in order to quantify the relationship between biofouling biomass (wet weight) and the vessel-level characteristics of recreational and fishing vessels. It was found that the number of days since the vessel was last cleaned strongly related to the biofouling biomass, yet differed dependent on vessel type. Similarly, the median number of trips undertaken was related to the biofouling biomass, and varied according to the type of antifouling paint (AF) used. No relationship was found between vessel size and biofouling biomass per sample unit. To reduce the spread of NIS, vessel owners should use an AF paint suitable to their vessel’s operational profile, and follow a maintenance schedule according to the paint manufacturer’s specifications.

Abstract

Beach nourishment is a widely used coastal adaptation strategy, though for some coastlines, debate exists as to its long-term viability to offset the impacts of sea level rise, due to limited sediment sources and negative environmental impacts. For beaches in bays and estuaries, in contrast to the open coast, wave energy is lower, decreasing required nourishment volumes, and bay shorelines around large cities are often already extensively disturbed. We examine whether nearshore-sourced beach nourishment is a viable long-term option for a range of lower energy shorelines across Port Phillip Bay, Australia. Sand volumes were estimated from sub-bottom profiling (75 km of shoreline to 2 km offshore) and grain size was compared against beaches. Shoreline recession was estimated for 1 m sea level rise to 2100, applying a high-end ‘Bruun’ response (likely on moderate energy shorelines), and a low-end ‘Beachface’ response (very low energy beaches). Offset nourishment volumes to maintain present-day beach width were calculated. Available sand volumes substantially exceeded projected offset nourishment volumes for 4 out of 5 zones. Moderate energy shorelines had sandbodies sufficient for long-term nourishment (4000 – 5000 m3/km/year; < 20% of available volume required). For low energy beaches, sediment volumes were plentiful but may be less viable due to higher mud content. A comparison between long-term nourishment requirements of open coast and bay beaches estimates 40 – 90% less sand is required for bay beaches, due to reduced shoreface extent. Accordingly, coastal managers should consider incorporating long-term beach nourishment into nature-based adaptation strategies for bay and estuarine coastlines.
Mechanism of thermally activated c-axis dissipation in layered High-T$_c$ superconductors at high fields

description: We propose a simple model which explains experimental behavior of $c$-axis resistivity in layered High-T$_c$ superconductors at high fields in a limited temperature range. It is generally accepted that the in-plane dissipation at low temperatures is caused by small concentration of mobile pancake vortices whose diffusive motion is thermally activated. We demonstrate that in such situation a finite conductivity appears also in $c$-direction due to the phase slips between the planes caused by the mobile pancakes. The model gives universal relation between the components of conductivity which is in good agreement with experimental data.

Unusual negative selection pressure and lack of adaptation in SARS-CoV-2 ancestors

description: Measures of the proportion of non-synonymous to synonymous mutations such as dN/dS are used to estimate selection forces acting on a genome, gene, or smaller region of that gene. Here a simple ratio of synonymous to non-synonymous mutations is applied to pairs of sequences ancestral to SARS-CoV-2 and also to non-SARS-CoV-2 related control groups. This analysis reveals between some pairs of close ancestors, and SARS-CoV-2, an unexpectedly high proportion of synonymous mutations, suggesting negative selection – even despite the switch in host species and tissue tropism. This suggests a need for further investigation.

description: Potential energy curves (PECs) of the lowest electronic states of the potassium mono-sulphide KS have been determined with highly correlated ab initio calculations, using internally contracted multi reference interaction configuration methods including Davidson correction (MRCI + Q) with and without considering spin-orbit effects. For the three low-lying bound states, we report a set of spectroscopic parameters including equilibrium distances, dissociation energies, vibrational and rotational constants. The effects of spin-orbit-induced changes on these parameters are also discussed. An analysis of the properties of the three bound states, X2Π, 12Σ+ and 22Π, illustrates the common characteristics of the whole series of compounds in the MS family (M = Li, Na, K, Rb, Cs). Indeed, the shapes of the PECs of these bound states are strongly affected by the interactions between the two ionic states, 2Σ+ and 2Π, correlating at large internuclear separations (RMS) to the first ionic dissociation limit [M+ + S−] and the electronic states correlating to the three/four lowest dissociation limits. The spectroscopy of these low-lying electronic states and the lifetime of their vibrational levels are thus affected by the spin-orbit interactions which are mainly related to the S atom and consequently common to all alkali-metal mono-sulphides.

description: This paper is dedicated to the solidification of a water drop impacting a cold solid surface. In a first part, we establish a 1D solidification model, derived from the Stefan problem, that aims at predicting the freezing dynamic of a liquid on a cold substrate, taking into account the thermal properties of this substrate. This model is then experimentally validated through a 1D solidification setup, using different liquids and substrates. In a second part, we show that during the actual drop spreading, a thin layer of ice develops between the water and the substrate, and pins the contact line at its edge when the drop reaches its maximal diameter. The liquid film then remains still on its ice and keeps freezing. This configuration lasts until the contact line eventually depins and the liquid film retracts on the ice. We measure and interpret this crucial time of freezing during which the main ice layer is built. Finally, we compare our 1D model prediction to the thickness of this ice pancake and we find a very good agreement. This allows us to provide a general expression for the frozen drop main thickness, using the drop impact and liquid parameters.

description: Using the PQSCHA semiclassical method, we evaluate thermodynamic quantities of one-dimensional Heisenberg ferro- and antiferromagnets. Since the PQSCHA reduces their evaluation to classical-like calculations, we take advantage of Fisher's exact solution to get all results in an almost fully analytical way. Explicitly considered here are the specific heat, the correlations length and susceptibility. Good agreement with Monte Carlo simulations is found for S>1 antiferromagnets, showing that the relevance of the topological terms and of the Haldane gap is significant only for the lowest spin values and temperatures.

description: Massless neutrino exchange leads to a new long-range force between matter. Recently, it was claimed both that the potential energy due to this interaction i) dominates the total energy of neutron stars and ii) that it is zero. We recalculate the energy of a neutrino propagating in a classical, uniform background of neutrons and find a negligible, but non-zero contribution to the total energy of neutron stars. We estimate the neutrino pair creation rate of a neutron star caused by a density gradient of the background neutrons but found it too small to be observable.

description: For any fixed graph $G$, the subgraph isomorphism problem asks whether an $n$-vertex input graph has a subgraph isomorphic to $G$. A well-known algorithm of Alon, Yuster and Zwick (1995) efficiently reduces this to the "colored" version of the problem, denoted $G$-$\mathsf{SUB}$, and then solves $G$-$\mathsf{SUB}$ in time $O(n^{tw(G)+1})$ where $tw(G)$ is the treewidth of $G$. Marx (2010) conjectured that $G$-$\mathsf{SUB}$ requires time $Ω(n^{\mathrm{const}\cdot tw(G)})$ and, assuming the Exponential Time Hypothesis, proved a lower bound of $Ω(n^{\mathrm{const}\cdot emb(G)})$ for a certain graph parameter $emb(G) \ge Ω(tw(G)/\log tw(G))$. With respect to the size of $\mathrm{AC}^0$ circuits solving $G$-$\mathsf{SUB}$ in the average case, Li, Razborov and Rossman (2017) proved (unconditional) upper and lower bounds of $O(n^{2κ(G)+\mathrm{const}})$ and $Ω(n^{κ(G)})$ for a different graph parameter $κ(G) \ge Ω(tw(G)/\log tw(G))$. Our contributions are as follows. First, we prove that $emb(G)$ is $O(κ(G))$ for all graphs $G$. Next, we show that $κ(G)$ can be asymptotically less than $tw(G)$; for example, if $G$ is a hypercube then $κ(G)$ is $Θ\big(tw(G)\big/\sqrt{\log tw(G)}\big)$. This implies that the average-case complexity of $G$-$\mathsf{SUB}$ is $n^{o(tw(G))}$ when $G$ is a hypercube. Finally, we construct $\mathrm{AC}^0$ circuits of size $O(n^{κ(G)+\mathrm{const}})$ that solve $G$-$\mathsf{SUB}$ in the average case, closing the gap between the upper and lower bounds of Li et al.

description: Most patients with pancreatic head cancer (85%) are jaundiced at presentation. Obstructive jaundice is thought to increase the risk of perioperative and postoperative complications. According to some experimental and clinical studies, preoperative biliary drainage (PBD) improves postoperative outcomes. However, numerous randomized studies found that PBD might increase postoperative complications rate. Thus, PBD or not is controversial. Objective: To confirm if PBD can be a routine or selective strategy in these patients. Material and Methods: A retrospective study comparing PBD with surgery alone in 200 jaundiced patients with pancreatic head cancer from 2nd Department of Surgery-Hellenic Red Cross Hospital of Athens (1996-2011). Data from patient’s files including: Age, gender, smoking, diabetes history, Laboratory parameters, procedures, post-operative course. Results: The majority of patients (62.5%) were males, with adenocarcinoma (93.5%), smokers (65.0%), and half of them were diabetics. The median age was 70 years, median tumor size was 5 cm, while PBD was performed in 74 patients (37.0%) with higher laboratory parameters (Direct bilirubin 18 mg/dl vs 13 mg/dl. Total bilirubin 24 mg/dl vs 20 mg/dl) and in this group was marked: higher postoperative complications rate, higher ICU admission rate, higher postoperative mortality (17.6% vs 5.6%). Conclusion: We believe that PBD should be a selective strategy in jaundiced patients with pancreatic head cancer in case of fever, non- operability of patients, and in case of more advanced disease as a palliative alternative since, this method increases postoperative complications rate.

description: The interaction mediated by irreducible pion and gluon exchange between constituent quarks is calculated and shown to have a strong tensor component, which tends to cancel the pion exchange tensor interaction between quarks. Its spin-spin component is somewhat weaker than the pion exchange spin-spin interaction, while its central and spin-orbit components are small in comparison to the corresponding single gluon exchange interactions. The combination of the $π-$gluon exchange interaction with the single pion exchange interaction and a weak gluon exchange interaction between constituent quarks has the qualitative features required for understanding the hyperfine splittings of the spectra of the nucleon and the $Δ$ resonances.

description: Acute and chronic liver failure can be tackled using liver transplantation. Graft dysfunction is still a challenge in 21st century. It affects up to one-third of the recipients, notwithstanding good to excellent long-term outcome have been reported. At the time of the writing of this chapter, the etiologic investigation of the organ dysfunction has revealed a multifactorial background. Despite the multifactorial causes, ischemia and reperfusion (I/R) injury is probably the most important contributing factor for organ dysfunction. Cholestasis, i.e., the stoppage or reduction of bile flow with or without bile duct loss or ductopenia and biliary ductular proliferations are frequent accompanying factors in I/R injury. However, they can be misleading, and they can also be present in other graft dysfunction conditions. Biliary marker levels increase usually as early as 5 days after transplantation. In this chapter, we reviewed a liver transplantation model as I/R injury model to study in detail the intermediate filaments of the cytoskeleton. We indicate that the phenotypic switch of the hepatocytes occurs earlier than frank cholestasis. We suggest that targeting this phenotypical switch of the liver cells may contribute to the savage or better outcome of the liver graft.
Quasi-static crack propagation in heterogeneous media

description: The dynamics of a single crack moving through a heterogeneous medium is studied in the quasi-static approximation. Equations of motion for the crack front are formulated and the resulting scaling behaviour analyzed. In a model scalar system and for mode III (tearing) cracks, the crack surface is found to be self affine with a roughness exponent of $ζ=1/2$. But in the usual experimental case of mode I (tensile) cracks, local mode preference causes the crack surface to be only logarithmically rough, quite unlike those seen in experiments. The effects of residual stresses are considered and found, potentially, to lead to increased crack surface roughness. But it appears likely that elastic wave propagation effects may be needed to explain the very rough crack surfaces observed experimentally.
