description: Image analysis using more than one modality (i.e. multi-modal) has been increasingly applied in the field of biomedical imaging. One of the challenges in performing the multimodal analysis is that there exist multiple schemes for fusing the information from different modalities, where such schemes are application-dependent and lack a unified framework to guide their designs. In this work we firstly propose a conceptual architecture for the image fusion schemes in supervised biomedical image analysis: fusing at the feature level, fusing at the classifier level, and fusing at the decision-making level. Further, motivated by the recent success in applying deep learning for natural image analysis, we implement the three image fusion schemes above based on the Convolutional Neural Network (CNN) with varied structures, and combined into a single framework. The proposed image segmentation framework is capable of analyzing the multi-modality images using different fusing schemes simultaneously. The framework is applied to detect the presence of soft tissue sarcoma from the combination of Magnetic Resonance Imaging (MRI), Computed Tomography (CT) and Positron Emission Tomography (PET) images. It is found from the results that while all the fusion schemes outperform the single-modality schemes, fusing at the feature level can generally achieve the best performance in terms of both accuracy and computational cost, but also suffers from the decreased robustness in the presence of large errors in any image modalities.

description: This paper reports the case of a female patient who underwent minimally invasive repair of pectus excavatum (MIRPE) in another service that evolved with bar rotation and cardiac perforation caused by the left stabilizer. The unique and frightening aspect of the case is that despite having the stabilizer inside the ventricle, the patient was oligosymptomatic: occasional chest pain and respiratory discomfort. Preoperative imaging showed rotation of the bar with stabilizers within the thoracic cavity. During surgery, intense ossification was observed around the prosthesis and it was noted that the left stabilizer had perforated the patient's left ventricle. Cardiac repair required a Clamshell incision and cardiopulmonary bypass. This case reinforces the validity of late radiological follow-up after MIRPE in an attempt to avoid this type of event, and the need to reevaluate the use of stabilizers perpendicular to the bar since they are not safe to prevent rotation of these implants.

description: We derive the Green-Schwarz action on AdS_5 x S^5 using an alternate version of the coset superspace construction. By Wick rotations and Lie algebra identifications we bring the coset to GL(4|4)/(Sp(4) x GL(1))^2, which allows us to represent the conformal transformations on unconstrained matrices. The derivation is more streamlined even for the bosonic sector, and conformal symmetry is manifest at every step. Kappa-symmetry gauge fixing is more transparent.

description: Spontaneous regression of malignant neoplasms is extremely rare, but renal cell carcinomas (RCC) are most often associated with this phenomenon.
We report a case of a patient with personal history of RCC, who underwent nephrectomy and no other oncological treatment. One year after nephrectomy, a lung metastasis was detected and kept under follow-up for 3 years. Its size increased over time until a needle biopsy was performed, and its metastatic nature confirmed. Wedge resection of the lung nodule was performed, and no neoplastic cells were found, suggesting its spontaneous regression after biopsy.
Different theories have been proposed to explain this phenomenon and, in most cases, the mechanism seems to involve the activation of the immune system. This case supports the importance of reducing tumor burden and the impact of the disturbance of the tumor microenvironment caused by instrumentation, in improving immune system activation and its essential role in neoplasm regression.

description: Total endovascular aortic arch repair is nowadays a promising alternative for selected patients with aortic arch disease. These endovascular procedures are technically challenging and require a diligent planning among all members of a multidisciplinary “Aorta Team” integrating cardiovascular anesthesiologists. In fact, endovascular aortic arch repair is a major challenge for anesthesiologists because of the risk of hemodynamic instability, cerebral events and acute kidney injury. In order to achieve the success, it is fundamental to discuss each patient in an individual basis, including perioperative management and care, and to be aware of surgical steps and their potential complications. Considering our previous experience with endovascular thoracoabdominal aortic surgery, we herein summarize our experience with anesthetic management of patients who underwent total endovascular aortic arch repair and its principal outcomes.

description: Lemierre syndrome is a rare, life-threatening condition characterized by an acute otorhinolaryngologic infection with septic thrombophlebitis of the internal jugular vein and septic embolism, particularly to the lungs. We describe a case of a previously healthy 15-year-old female patient who initially presents fever and odynophagia but quickly develops neck and pleuritic chest pain. Computed tomography was performed and the radiological findings confirmed the diagnosis of a Lemierre syndrome. She was managed with antibiotics, anticoagulant for three days and symptomatic treatment, with a gradually improving condition. After 17 days of hospitalisation, due to reappearance of pleuritic pain, a new imaging assessment was performed and showed additional septic emboli in the lungs, which prompted the reintroduction of anticoagulant therapy. Awareness of the existence of this syndrome is essential to ensure a radiological evaluation with computed tomography and thus timely diagnosis and treatment.

description: Properties of hypernuclei $_{ΛΛ}^5$H and $_{ΛΛ}^5$He are studied in a two-channel approach with explicit treatment of coupling of channels ^3\text{Z}+Λ+Λand α+Ξ. Diagonal ΛΛand coupling ΛΛ-ΞN interactions are derived within G-matrix procedure from Nijmegen meson-exchange models. Bond energy ΔB_{ΛΛ} in $_{ΛΛ}^5$He exceeds significantly that in $_{ΛΛ}^5$H due to the channel coupling. Diagonal Ξαattraction amplifies the effect, which is sensitive also to Λ-core interaction. The difference of the ΔB_{ΛΛ} values can be an unambiguous signature of the ΛΛ-ΞN coupling in ΛΛhypernuclei. However, improved knowledge of the hyperon-nucleus potentials is needed for quantitative extraction of the coupling strength from future data on the ΛΛhypernuclear binding energies.

description: In this paper we first address four point functions of string amplitudes in both type IIA and IIB string theories. Making use of non-BPS scattering amplitudes, we explore not only several Bianchi identities that hold in both transverse and world volume directions of brane, but also reveal various new couplings. These couplings can just be found by taking into account the mixed pull-back and Taylor couplings where their all order alpha-prime higher derivative corrections have been derived as well. For the first time, we also explore the complete form of a six point non-BPS amplitude, involving three open string tachyons, a scalar field and a Ramond-Ramond closed string in both IIA, IIB. In a special limit of the amplitude and using the proper expansion we obtain an infinite number of bulk singularities that are being constructed in the effective field theory. Finally using new couplings we construct all the other massless and tachyon singularities in type IIA, IIB string theories. All higher derivative corrections to these new couplings to all orders in $α'$ and new restricted Bianchi identities have also been gained.

description: The saphenous vein graft (SVG) remains the most used conduit as a second graft in Coronary Artery Bypass Grafting (CABG).1 Traditionally, surgeons harvest SVG with an open approach, making a long incision along the medial part of the leg or thigh. This procedure can potentially result in important complications, such as delayed wound healing, postoperative pain and infection.2 Thus, less invasive techniques for vessel harvesting have grown in popularity. Endoscopic vein harvesting (EVH) is a minimally invasive harvesting procedure, which only requires a short incision, leading to less wound complications and a faster return to normal daily activities.

This article intends to describe how we do EVH technique in our centre, from the preparation of the patient to the postoperative period and share some tips and tricks from our experience.

Spin-polarized current amplification and spin injection in magnetic bipolar transistors
Creators: name: Fabian, Jaroslav
name: Zutic, Igor
Publisher: name: arXiv
Year: 2003
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: The magnetic bipolar transistor (MBT) is a bipolar junction transistor with an equilibrium and nonequilibrium spin (magnetization) in the emitter, base, or collector. The low-injection theory of spin-polarized transport through MBTs and of a more general case of an array of magnetic {\it p-n} junctions is developed and illustrated on several important cases. Two main physical phenomena are discussed: electrical spin injection and spin control of current amplification (magnetoamplification). It is shown that a source spin can be injected from the emitter to the collector. If the base of an MBT has an equilibrium magnetization, the spin can be injected from the base to the collector by intrinsic spin injection. The resulting spin accumulation in the collector is proportional to $\exp(qV_{be}/k_BT)$, where $q$ is the proton charge, $V_{be}$ is the bias in the emitter-base junction, and $k_B T$ is the thermal energy. To control the electrical current through MBTs both the equilibrium and the nonequilibrium spin can be employed. The equilibrium spin controls the magnitude of the equilibrium electron and hole densities, thereby controlling the currents. Increasing the equilibrium spin polarization of the base (emitter) increases (decreases) the current amplification. If there is a nonequilibrium spin in the emitter, and the base or the emitter has an equilibrium spin, a spin-valve effect can lead to a giant magnetoamplification effect, where the current amplifications for the parallel and antiparallel orientations of the the equilibrium and nonequilibrium spins differ significantly. The theory is elucidated using qualitative analyses and is illustrated on an MBT example with generic materials parameters.

description: Abstract: "Natural deduction (for short: nd-) calculi have not been used systematically as a basis for automated theorem proving in classical logic. To remove objective obstacles to their use I describe (1) a method that allows to give semantic proofs of normal form theorems for nd-calculi and (2) a framework that allows to search directly for normal nd-proofs. Thus one can try to answer the question: How do we bridge the gap between claims and assumptions in heuristically motivated ways? This informal question motivated the formulation of intercalation calculi. Ic- calculi are the technical underpinnings for (1) and (2), and the paper focuses on their detailed presentation and meta-mathematical investigation -- in the case of classical predicate logic."

description: Introduction: Congenital thoracic disorders represent a spectrum of fetal lung bud development abnormalities, which may affect breathing capacity and quality of life. We aim to evaluate the impact of surgery in the treatment of 4 major congenital conditions.

Materials and Methods: We performed a retrospective cohort analysis of patients who underwent surgical treatment in our tertiary center, from 2007 to 2022.

Results: Over the 15-year period, we treated 33 patients, with a male predominance of 55%. 22 patients (67%) were asymptomatic. When symptomatic, the recurrence of respiratory infections was the most common clinical presentation (18%). In 13 patients (39%), diagnosis was achieved through fetal ultrasonography. This study encompassed 13 patients with pulmonary sequestration (39%), 11 patients with bronchogenic cysts (33%), 7 patients with congenital pulmonary airway malformation (21%) and 2 patients with congenital lobar emphysema (6%). Considering solely lung malformation conditions, we accounted 22 patients with a median age of 3 [1-67] years-old. Surgery comprised bilobectomy (9%), lobectomy (77%), lobectomy with wedge resection (5%), segmentectomy (5%) and wedge resection (5%). Concerning bronchogenic cysts, we treated 11 patients with a median age of 19 [14-66] years-old. We identified 1 hilar, 1 intrapulmonary and 9 mediastinal lesions, of which 4 were paraesophageal, 4 were subcarinal and 1 was miscellaneous. Overall, surgery was conducted by thoracotomy in 61% of patients, VATS in 33% and RATS in 6%. The median drainage time was 3 [1-40] days and median hospital stay was 4 [1-41] days. There were no cases of mortality. Ensuing, 94% of patients experienced clinical improvement after surgery.

Conclusion: Early diagnosis of congenital thoracic malformations increased considerably with the improvement in imaging technology and prenatal screening. Treatment may include expectant conservative treatment. However, in selected cases, surgery may play an important role in symptomatic control and prevention of disease progression.

description: Oxygen K-edge X-ray absorption spectra of liquid water are computed based on the configurations from advanced ab initio molecular dynamics simulations, as well as an electron excitation theory from the GW method. One one hand, the molecular structures of liquid water are accurately predicted by including both van der Waals interactions and hybrid functional (PBE0). On the other hand, the dynamic screening effects on electron excitation are approximately described by the recently developed enhanced static Coulomb hole and screened exchange approximation by Kang and Hybertsen [Phys. Rev. B 82, 195108 (2010)]. The resulting spectra of liquid water are in better quantitative agreement with the experimental spectra due to the softened hydrogen bonds and the slightly broadened spectra originating from the better screening model.

description: We consider a geometric zero-radius limit for strings on $AdS_5\times S^5$, where the anti-de Sitter hyperboloid becomes the projective lightcone. In this limit the fifth dimension becomes nondynamical, yielding a different "holographic" interpretation than the usual "bulk to boundary" one. When quantized on the random lattice, the fifth coordinate acts as a new kind of Schwinger parameter, producing Feynman rules with normal propagators at the tree level: For example, in the bosonic case ordinary massless $ϕ^4$ theory is obtained. In the superstring case we obtain new, manifestly ${\cal N}=4$ supersymmetric rules for ${\cal N}=4$ super Yang-Mills. These gluons are also different from those of the usual AdS/CFT correspondence: They are the "partons" that make up the usual "hadrons" of the open and closed strings in the familiar QCD string picture. Thus, their coupling $g_{YM}$ and rank $N$ of the "color" gauge group are different from those of the "flavor" gauge group of the open string. As a result we obtain different perturbation expansions in radius, coupling, and 1/N.

description: CeNiSn is a Kondo semimetal where a gap opens at low temperatures due to hybridization between 4$f$ and conduction electrons, but a full insulating state fails to develop. Upon the insertion of hydrogen, long range magnetic order is induced. Here we report zero-field muon-spin relaxation and inelastic neutron scattering measurements of polycrystalline samples of the deuterides CeNiSnD$_x$ ($x$=1.0, 1.8). The muon-spin relaxation results confirm magnetic ordering in the whole sample of CeNiSnD below around 4.7 K, while inelastic neutron scattering reveals two well-defined crystalline-electric field (CEF) excitations at around 13 meV and 34 meV in CeNiSnD, and 5 meV and 27 meV for CeNiSnD$_{1.8}$. These results suggest that hydrogenation leads to the localization of the Ce-4$f$ electrons, giving rise to long-range magnetic order. We propose CEF level schemes for both systems, which predict a ground state moment of 0.96$μ_{\rm B}$/Ce within the $ab$-plane for CeNiSnD$_{1.8}$ and a saturated moment of 1.26$μ_{\rm B}$/Ce along the easy $c$ axis for CeNiSnD, that account for the observed magnetic properties.

description: The Center for Design of Educational Computing (CDEC), in collaboration with faculty in the Department of Philosophy, has made major progress with modest funding this year in the development of a unique intelligent tutor to guide and teach (a) the construction of proofs in mathematical logic and formal theoretical domains (eg., Boolean algebra, social choice theory, elementary probability theory . . .) and (b) logical problem solving (eg., the formal reconstruction of arguments, logic puzzles and word problems presented in natural language). We have no funding for this project beyond June '88. A grant on the order of $50K would support (full time) one applications programmer and (part time) a systems programmer and research scientist to continue our work, with philosophy faculty, for another year, while we seek follow-on funding. I outline here the significant work we could accomplish even with this level of funding and the very visible impact it would have, especially on campus, in the coming year.

description: To fathom the mechanism of high-temperature ($T_{\rm c}$) superconductivity, the dynamical vertex approximation (D$Γ$A) is evoked for the two-dimensional repulsive Hubbard model. After showing that our results well reproduce the cuprate phase diagram with a reasonable $T_{\rm c}$ and dome structure, we keep track of the scattering processes that primarily affect $T_{\rm c}$. We find that local particle-particle diagrams significantly screen the bare interaction at low frequencies, which in turn suppresses antiferromagnetic spin fluctuations and hence the pairing interaction. Thus we identify dynamical vertex corrections as one of the main oppressors of $T_{\rm c}$, which may provide a hint toward higher $T_{\rm c}$'s.

Case of 21-year-old male, history of congenital heart disease (severe right ventricle hypoplasia and pulmonary artery stenosis with extracardiac cavo-pulmonary shunt (Fontan surgery), and atrial septal defect). Brought to the Emergency Department due to a Mallory-Weiss syndrome, upper-endoscopy “laceration at esophagogastric junction (EGJ) with active bleeding”, clips were applied. However, worsening shock, repeated melenas and hematemesis, hemoglobin drop, lactate 2.8mmol/L, and needing noradrenaline (1.21mcg/kg/min). Due to active blood loss and worsening shock, the patient was intubated to maintain airway protection. Repeated upper-endoscopy “voluminous live red clot at EGJ, 4-clips and active bleeding of mucosa between, injection of polidocanol”. Despite the implemented strategy, high risk of rebleeding remained. Following invasive mechanical ventilation (IMV), sustained hypotension having to increase noradrenaline (1.52mcg/kg/min) and lactate (5.8mmol/l), despite fluid resuscitation. Echocardiogram evidenced severe ventricular dysfunction, and fixed inferior vena cava (IVC) of 20mm. The heart defect combined with positive intrathoracic pressure, contributed to the worsened shock, as Fontan circulation is dependent on low vascular resistance to maintain output2. Needing VA-ECMO and admitted to ICU, volemia optimization, adjusting ventilation to lower intrathoracic pressure and started on milrinone and sildenafil. Another upper-endoscopy showed laceration at EGJ, with placement of clips. Echocardiogram revealed “Normal left ventricle. Hypoplastic right ventricle. Mild mitral regurgitation; aortic VTi 19cm. IVC 22mm. RV/RA gradient 70mmHg. Interatrial bidirectional shunt”. Favorable evolution permitted extubation, suspension of milrinone and sildenafil, followed by decannulation.
With rescue ECMO, congenital heart disease are salvageable despite sudden decompensation3. This case, positive intrathoracic pressure impairs the Fontan circulation, dependent on preload and higher central venous pressure to maintain cardiac output, as the ventricle is unable to compensate increased demands2, and worsening shock.

description: Introduction: Worldwide, there is an increase in scrutiny after surgical treatment of a vast array of pathologies. Doing so, a large body of evidence clearly supports centralisation, such as teaching hospitals, where a larger caseload enables optimal outcomes. These institutions have a strong presence of surgical residents seeking training in both technical and non-technical skills. Inevitably, as part of training, they will be involved in the surgical treatment of those patients, even as the primary operator. We sought to investigate the impact of trainee performed procedures in outcomes of common vascular procedures of different technical complexity.

Methods: A non-systematic MEDLINE and Scopus databases review on the outcomes of resident performed common vascular procedures was performed.

Results: Specific evidence in many procedures (venous disease, aortic aneurysms, peripheral artery disease) is lacking. After carotid endarterectomy (CEA), resident performed procedures seem to have similar cranial nerve palsy and stroke when compared to expert surgeons. Generally, resident-performed primary radiocephalic and elbow arteriovenous fistula (AVF) presents similar primary and secondary patency. As with CEA, AVF procedures performed by residents took longer. On aortic aneurysms, although no specific comparison has been performed, resident involvement (irrespective of surgeon or assistant) in these procedures does not seem associated with increased adverse events.

Conclusion: In most vascular surgery procedures, little is known about resident performance and their impact on outcomes. Notwithstanding, resident-performed CEA and primary AVF seem free of major compromise to patients. Further research is warranted to clarify this topic.

description: The purpose of the Benedum grant was to allow Carnegie Mellon to develop the infrastructure needed to bring discipline and leadership to the growing area of educational computing. As computer technology advances at a rapid rate and its promise for improving education both tantalizes and confounds us, it becomes imperative that dedicated centers be created to track and tame the technology, centers of knowledge for realizing the promise and avoiding the pitfalls of advancing technology, development centers for implementing the most promising applications of the technology for education.

description: The flameless atomic absorption signals of chromium, nickel and selenium are subject to matrix interferences arising from inorganic salts and anions commonly found in urine. The effects of such salts on the atomic absorption signals were investigated using Polarized Zeeman Effect background correction in conjunction with a detector/readout system capable of resolving absorbance signals in 18 msec readings. Both optical temperature control and current temperature control were employed for each analysis. Peak area, peak height, peak shape and appearance time were compared for matrix-free standards and matrix-containing standards.

The influence of the inorganic salts on the metal analyses was found to be significant. Calcium and magnesium enhanced chromium, nickel and selenium signals, although it appeared the cations acted via different mechanisms. Suppression of the signals by phosphate, nitrate or sulfate was most likely caused by absorption from diatomic species formed in the furnace. Such species exhibit structured background and produce Zeeman spectra in a magnetic field. Although use of optical temperature control improved sensitivities and detection limits, the effects of matrix components were the same whether optical or current control was used.

Urine could not be analyzed directly for the metals studied, Adjustments of the furnace heating program should improve the analyses but dilution, matrix modification and the method of standard additions would still be required.

description: Introduction: Blunt thoracic aortic injuries (BTAI) once had mortality rates up to 32%, but the advent of thoracic endovascular aortic repair (TEVAR) has significantly improved outcomes. However, concerns persist regarding long-term devicerelated complications, device integrity in aging aortas, and the criteria for selecting patients for endovascular repair. We aimed to assess BTAI treatment strategies based on injury grade and their associated outcomes.

Methods: A systematic search of MedLine and Scopus databases was conducted to identify original articles published after 2013, which provided information on injury characteristics, outcomes, secondary effects, and reinterventions following BTAI. We classified aortic injuries following the SVS Clinical Practice Guidelines.

Results: We included 28 studies involving 1888 BTAI patients, including 5 prospective studies. Most patients were under 45 years old (86.4%), and grade III injuries were the most common (901 patients), followed by grades I and II (307 and 291 patients, respectively). TEVAR was performed in 1458 patients, mainly with grade III and IV injuries (1040 patients). Approximately half of the grade I injuries (153 of 307) were treated with TEVAR. Thirty-day mortality rate was 11.2%, primarily due to associated injuries. Aortic-related deaths were reported in 21 studies, with an overall rate of 2.2%, but none occurred beyond the first 30 days. Partial or complete coverage of the left subclavian artery was performed in 522 patients, with 27.9% requiring immediate or delayed revascularization. Aortic reintervention rates were relatively low (3.9%).

Conclusion: TEVAR effectively treats BTAI grades III and IV, with potential benefit for some grade II injuries with more aggressive early intervention. Despite SVS guidelines suggesting conservative management for grade I injuries, there is a substantial rate of intervention with positive outcomes and low mortality. Long-term follow-up data, extending up to almost 20 years, reveal the durability of grafts, aortic remodeling, and minimal reintervention and complications.

description: In this talk we review the important role played by chiral SU(3) symmetry in hadron physics. Exciting new results on the formation of baryon resonances as implied by chiral coupled-channel dynamics are presented and discussed. The results are the consequence of progress made in formulating a consistent effective field theory for the meson-baryon scattering processes in the resonance region. Strangeness channels are found to play a decisive role in the formation of resonances. As a further application of chiral coupled-channel dynamics the properties of antikaons and hyperon resonances in cold nuclear matter are reviewed.

description: We introduce the exit time finite state projection (ETFSP) scheme, a truncation-based method that yields approximations to the exit distribution and occupation measure associated with the time of exit from a domain (i.e., the time of first passage to the complement of the domain) of time-homogeneous continuous-time Markov chains. We prove that: (i) the computed approximations bound the measures from below; (ii) the total variation distances between the approximations and the measures decrease monotonically as states are added to the truncation; and (iii) the scheme converges, in the sense that, as the truncation tends to the entire state space, the total variation distances tend to zero. Furthermore, we give a computable bound on the total variation distance between the exit distribution and its approximation, and we delineate the cases in which the bound is sharp. We also revisit the related finite state projection scheme and give a comprehensive account of its theoretical properties. We demonstrate the use of the ETFSP scheme by applying it to two biological examples: the computation of the first passage time associated with the expression of a gene, and the fixation times of competing species subject to demographic noise.

description: Considerable delays often exist between the discovery of a vulnerability and the issue of a patch. One way to mitigate this window of vulnerability is to use a configuration workaround, which prevents the vulnerable code from being executed at the cost of some lost functionality -- but only if one is available. Since program configurations are not specifically designed to mitigate software vulnerabilities, we find that they only cover 25.2% of vulnerabilities. To minimize patch delay vulnerabilities and address the limitations of configuration workarounds, we propose Security Workarounds for Rapid Response (SWRRs), which are designed to neutralize security vulnerabilities in a timely, secure, and unobtrusive manner. Similar to configuration workarounds, SWRRs neutralize vulnerabilities by preventing vulnerable code from being executed at the cost of some lost functionality. However, the key difference is that SWRRs use existing error-handling code within programs, which enables them to be mechanically inserted with minimal knowledge of the program and minimal developer effort. This allows SWRRs to achieve high coverage while still being fast and easy to deploy. We have designed and implemented Talos, a system that mechanically instruments SWRRs into a given program, and evaluate it on five popular Linux server programs. We run exploits against 11 real-world software vulnerabilities and show that SWRRs neutralize the vulnerabilities in all cases. Quantitative measurements on 320 SWRRs indicate that SWRRs instrumented by Talos can neutralize 75.1% of all potential vulnerabilities and incur a loss of functionality similar to configuration workarounds in 71.3% of those cases. Our overall conclusion is that automatically generated SWRRs can safely mitigate 2.1x more vulnerabilities, while only incurring a loss of functionality comparable to that of traditional configuration workarounds.

description: Authentication protocols based on an asymmetric keypair provide strong authentication as long as the private key remains secret, but may fail catastrophically if the private key is lost or stolen. Even when encrypted with a password, stolen key material is susceptible to offline brute-force attacks. In this paper we demonstrate a method for rate-limiting password guesses on stolen key material, without requiring special hardware or changes to servers. By slowing down offline attacks and enabling easy key revocation our algorithm reduces the risk of key compromise, even if a low-entropy password is used.
