Use of tryptophan phosphorescence to assess protein-solvent dynamic coupling in native and mutant glucokinase
Creators: name: Lewerissa, Karina Bianca
Publisher: name: No Publisher Supplied
Year: 2022

description: Tryptophan phosphorescence decay rates had been used to observe protein dynamics inglucokinase (GK) enzyme, a multi tryptophan protein with 3 tryptophan residues at sequence positions 99, 167, and 257. Three GK mutant enzymes, namely W99, W167, and W257, that contain only one tryptophan residue were used to investigate how local environment at a specific site in the protein determines the spectral properties of tryptophan. The intensity decay rates of tryptophan phosphorescence in those enzymes in different conformational states (free, bound to glucose, and denatured by heat) were collected over a wide range of temperature from 77K, from glassy state through rubbery state far above the solvent glass transition (Tg) of the cryosolvent. Decay rates were interpreted in terms of dynamic quenching by local matrix molecular mobility.Data show that the molecular mobility of the enzymes as a function of temperature can be separated into 3 kinetic regimes, which we name as process I, II, and III. The dynamic behaviors of process I and II follow Arrhenius law. Process I (at 77 – 170 K) of all enzymes under all conditions are marked by low activation energy (Eᴀ) and small frequency factors which indicate small normal modes of vibration and inefficiency of the quenching process. Process II (at 170 – 200 K) has the same temperature dependence as the beta fluctuations of the protein hydration shell, indicating that the dynamic motions of proteins are slaved to the hydration shell, but with lower rate. Process III (at > 200 K) is explained by Vogel-Fulcher-Tamman (VFT) law and follows the motions of bulk solvent (viscosity) with smaller magnitude. The relaxation processes of W99, where the tryptophan residue is at the protein surface, differs from the other enzymes. W99 suffers quenching process much greater in process II and III compared to other enzymes, likely due to tighter coupling with solvent dynamics. Those results show that tryptophan phosphorescence is useful as a probe for monitoring molecular mobility with specific site information.In order to improve the accuracy of the method, several different cryosolvents (glycerol water 75% v/v, glycerol water 90% v/v, ethylene glycol water 75% v/v, propylene glycol water 75% v/v, and aqueous sucrose and trehalose solutions) were used to measure the natural radiative decay rate of tryptophan, tyrosine, and their derivatives N-acetyl-tryptophanamide (NATA) and N-acetyl-tyrosinamide (NTyrA) at liquid nitrogen temperature (77 K). Different phosphorescence lifetimes at 77 K obtained from tyrosine, tryptophan and their derivatives in the different cryosolvents could reflect either their sensitivity to the solvent medium or residual matrix mobility at 77K. The effects of those factors need to be confirmed by observing phosphorescence decay kinetics at much lower temperature (4 K) to get clearer understanding of what causes the variation of lifetime in different solvents.

The allele frequency distribution and forensic parameters of the two populations were reported in this paper. The results show these 22 STR loci have high or medium power of discrimination and probabilities of exclusion. The Hardy–Weinberg Equilibrium of each locus were tested. The genetic distances (i.e., Fst) among the two population and other Chinese populations were estimated. The results showed that these loci are available in forensic genetics and may prove useful in both human identification and kinship analysis.

description: The purpose of this study is to estimate sex from lip print pattern. Sex estimation is important to identify whether the crime has been committed by a male or female or to identify the perpetrator. Cheiloscopy is the study of lip print pattern, which is very useful in forensic identification of a person. Lip prints are actually lines and fissures in the form of wrinkles in the zone of transition of lip i.e. red part of lips. These ridges, grooves or wrinkles are studied for the purpose of positive identification of a person. Lip prints can also prove to be as one of the best method of personal identification. Lip print is unique to individual and thus can be used for identification purpose. Lip prints are important evidence in case like sexual assault, murder, rape and also remain at scene of crime unknowingly on cups, glasses, cigarette butts, clothing’s, skin etc.

description: Trustworthy operation of control systems and critical infrastructures, such as industrial control systems (ICS) or cyber physical systems (CPS) requires a secure and real-time code execution environment. Due to the importance and larger attack surfaces of these platforms, they are becoming attractive targets for malicious penetrations lead- ing to catastrophic failures with substantive impact. A promising defense against these attacks is to monitor the system states through physical side-channel signals. Physical side-channel monitors impose zero overhead to the target system, which is highly favorable for resource-constrained and real-time systems. Physical side-channel monitors are constructed based on side-channel signals in a data-driven fashion. Therefore, they benefit a lot from artificial intelligence (AI) techniques. AI has also been established as a popular class of algorithms for more general CPS such as autonomous systems. How- ever, the recently emerging studies on the adversarial robustness of AI models put their security in question: ”Are AI-powered systems as trustworthy as commonly thought?”This dissertation aims at investigating using AI to ensure trustworthy security and studying the security of AI-powered systems. First, I provide a tutorial-level discussion on utilizing structures in physical side-channel signals and AI models to construct physical side-channel monitors. Next, I look closer at Zeus, an AI-powered electromagnetic side-channel monitor I proposed. Zeus collects electromagnetic emanations from the micro-controller of a system and constructs a recurrent neural network-based anomaly detector to ensure the execution control flow integrity of the system. I evaluated Zeus on a commercial programmable logic controller (PLC) using real applications. Zeus was able to distinguish benign and malicious executions with an average accuracy of 98.8% and zero overhead. Additionally, I study the adversarial robustness of physical side-channel monitors such as Zeus by proposing a novel attack approach to bypass such a monitor. I customize a Chipwhisperer, a popular side-channel attack testbed, to evaluate the proposed attack. The proposed attack was able to bypass power side-channel monitors on various control programs under different control attacks. The attack is also robust across detector models and hardware implementations. Finally, to study the security of more general AI, I proposed a novel physical adversarial attack against autonomous systems by exploiting the optical sensor pipeline. I designed a low-cost and portable gadget to evaluate the proposed attack. The attack can cause up to 99% attack success rate and survive much stronger environmental light conditions compared to prior work.

description: A new report of necrophagous blowfly, Calliphora vicina (Diptera: Calliphoridae), larvae from a human corpse found in the bathroom of a house during winter in Shiraz, Fars province, south of Iran, is presented. An autopsy revealed that the cadaver was an 83-year-old solitary-living Iranian female having a stroke during bath. The minimum time elapsed since death was estimated to have been less than 5 days prior to the discovery of the bloated cadaver at defined ambient temperatures. As such, this synanthropic species was associated with the early wave of colonizing cadaver-feeding insects that were found on a corpse after death. This is the first corroborated evidence of a forensic entomology case involving this bluebottle blowfly species of insect in south of Iran and this species can be helpful in the future to support the estimation on the time elapsed since death in this region.

description: We discuss the stability of highly degenerate zero-energy states tha appear at the surface of a nodal superconductor preserving time-reversal symmetry. The existence of such surface states is a direct consequence of the nontrivial topological numbers defined in the restricted Brillouin zones in the clean limit. In experiments, however, potential disorder is inevitable near the surface of a real superconductor, which may lift the high degeneracy at zero energy. We show that an index defined in terms of the chiral eigenvalues of the zero-energy states can be used to measure the degree of degeneracy at zero energy in the presence of potential disorder. We also discuss the relationship between the index and the topological numbers.

description: Giant cell myocarditis is also known as ‘Granulomatous myocarditis’, of which Idiopathic giant cell myocarditis (IGCM) is a rare clinicopathological entity. IGCM is known to cause sudden death in healthy adults in the absence of any symptomatic heart disease. While performing autopsies if there is no apparent cause of death the autopsy surgeon must keep in mind IGCM, especially in healthy adults with an unexplained sudden death. We report here series of two cases of unexpected sudden death in an undiagnosed heart disease and the utility of histopathological diagnosis after autopsy when other ancillary techniques are unavailable.

description: Background: Nowadays, STR polymorphism is the method of choice in all governmental and private laboratories working in DNA profiling, since it allows DNA investigators to analyze all types of biological evidences, besides obtaining high discrimination power for a large number of cases including both criminal identification and paternity tests as well. Azoospermia is a condition that when occurs in certain individual it causes a complete absence of the major DNA source in semen which is spermatozoa leading to infertility. The aim of this study is to obtain STR profiles from those minute DNA quantities that might be present in the semen stain evidences of Azoospermic individuals, to generate confidential results presented to the court after the analysis of these special type of biological evidences. Methods: 100 semen stain trace samples divided into two groups (test & control samples) were recovered by a simulating manner to that which is done in the crime scene investigation, then DNA was extracted using QIAamp DNA Micro Kit, with special modifications in the extracting procedure applied for the Azoospermic test samples to concentrate and obtain minute quantities of DNA. DNA quantification was done using a Real-time PCR utilizing Quantifiler Duo Kit. PCR was done using an AmpFlSTR Y-Filer Kit, then amplified products for all test and control samples were typed using a 3130 Genetic Analyzer. Results: Full Y-STR profiles were obtained from semen stain evidences attributed to Azoospermic individuals, with a percentage reaches 100%. Conclusion: The methodology followed in this research should be applied in case of performing DNA typing for semen stain evidences recovered from crime scenes, to guarantee obtaining full DNA profiles even with Azoospermic samples.

description: Background: For interferon beta-1a subcutaneously three times weekly (IFN β-1a SC tiw), administration options include manually injected prefilled syringes; a preassembled, single-use autoinjector; and a reusable autoinjector. This study evaluated patient-perceived ease of use of two injection devices. Research design and methods: REDEFINE, a Phase IV, multicenter crossover study, randomized patients with multiple sclerosis and ≥5 weeks’ IFN β-1a 44 μg SC tiw use to 4 weeks using a single-use autoinjector, then 4 weeks using a reusable autoinjector, or vice versa. The primary endpoint was the proportion rating each ‘easy’ or ‘very easy’, with/without regard to previous device experience. Results: Of 97 randomized patients, 29 had most recent experience with manual injection; 23 with single-use autoinjector; and 45 with reusable autoinjector. 68.4% found using the single-use autoinjector very easy or easy, versus 77.9% for the reusable device (difference −9.5%; p = 0.200). 40.0% versus 29.5% found the respective devices very easy (difference 10.5%; p = 0.203). Conclusions: Most patients found both autoinjectors easy or very easy to use. Having two viable options may help accommodate patient preferences. Ease of administration and patient satisfaction relates to adherence; satisfied patients may more likely be adherent. Trial registration: The trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT02019550).

description: Degenerate parametric amplifiers (DPAs) exhibit the unique property of phase-sensitive gain and can be used to noiselessly amplify small signals or squeeze field fluctuations beneath the vacuum level. In the microwave domain, these amplifiers have been utilized to measure qubits in elementary quantum processors, search for dark matter, facilitate high-sensitivity spin resonance spectroscopy and have even been proposed as the building blocks for a measurement based quantum computer. Until now, microwave DPAs have almost exclusively been made from nonlinear Josephson junctions, which exhibit high-order nonlinearities that limit their dynamic range and squeezing potential. In this work we investigate a new microwave DPA that exploits a nonlinearity engineered from kinetic inductance. The device has a simple design and displays a dynamic range that is four orders of magnitude greater than state-of-the-art Josephson DPAs. We measure phase sensitive gains up to 50 dB and demonstrate a near-quantum-limited noise performance. Additionally, we show that the higher-order nonlinearities that limit other microwave DPAs are almost non-existent for this amplifier, which allows us to demonstrate its exceptional squeezing potential by measuring the deamplification of coherent states by as much as 26 dB.
Enhancing disease resistance and yield traits of European hazelnut (Corylus avellana) using genomic technologies
Creators: name: Lombardoni, Justin J.
Publisher: name: No Publisher Supplied
Year: 2022

description: European hazelnut (Corylus avellana) is a widely produced tree nut crop, currently ranking fifth in the world with approximately 1,000,000 ha planted and 1,125,000 metric tons harvested per year. Corylus avellana is the primary hazelnut species produced commercially due to its superior nut traits, and most production takes place in regions with a Mediterranean-like climate. Anisogramma anomala is an ascomycete fungus that causes eastern filbert blight (EFB) on hazelnut. It is native to the United States east of the Rocky Mountains, where it has prevented commercial hazelnut production. This pathogen colonizes the vascular tissue and ultimately kills most trees lacking genetic resistance or tolerance. Most C. avellana trees are highly susceptible to this disease, whereas the wild American hazelnut (C. americana), which is native to a wide area of the eastern United States, is typically resistant or tolerant, and often displays few if any symptoms. The purpose of this research was to first characterize novel EFB resistant/tolerant germplasm in the context of C. avellana genetic diversity using single nucleotide polymorphism (SNP) markers developed through next-generation sequencing (NGS). The same genotyping process was then used in conjunction with simple sequence repeat (SSR) markers to map quantitative trait loci (QTLs) for EFB resistance/tolerance using three C. americana × C. avellana interspecific mapping populations. The same three mapping populations were also used to map eight different nut/kernel traits in hazelnut, which included nuts per cluster, nut mass, kernel mass, kernel percentage, nut sphericity, kernel sphericity, kernel fiber, and blanching. As many as ten different genetic groups were identified across the C. avellana germplasm, and EFB resistant/tolerant germplasm was found within nine of these groups, indicating significant genetic diversity is present in resistant accessions. Further, five QTLs spanning three genetic regions were identified for EFB resistance/tolerance in the interspecific mapping populations, with QTLs on linkage group (LG) 10 and LG 11 indicating novel sources of resistance. Lastly, a total of 45 QTLs, 37 of which controlled at least 10% of the phenotypic variation for their assigned trait, were identified across the different nut/kernel traits evaluated. Overall, this body of research showed that EFB resistance and tolerance is found in a diverse range of genetic backgrounds, supporting that breeding for resistance need not be equated with narrowing genetic diversity. It also identified multiple loci controlling important disease resistance and production traits that can support marker aided breeding and other genomics-based breeding approaches. These loci hold promise for more efficient development of improved European and hybrid (C. americana × C. avellana) hazelnut cultivars.

description: Astronomical tests of spacetime metric and gravitation theory near the Galactic Center (GC) black hole, Sgr A* have gained momentum with the observations of compact stellar orbits near the black hole and measurement of the black hole shadow. Deviation from the Kerr metric is a potential signature of modified gravity theory. In this work, we use Newman-Janis algorithm to construct an axially symmetric and asymptotically flat metric in f(R) scalaron gravity theory. We call it as Kerr-scalaron metric. For studying astronomical consequences of the new metric we use the compact stellar orbits and the black hole shadow. We use the observed size of the emission ring of the GC black hole shadow for estimating deviation of the new metric from general relativity. It has been found that scalarons with mass within $10^{-17}$ eV - $10^{-16}$ eV are compatible with the observed emission ring size for black hole spin $χ=0.9$. Schwarzschild limit of the pericenter shift is estimated for compact stellar orbits near the black hole. General relativistic pericenter shift in wider orbits including S-stars such as S4716 and S2 has been reproduced with these scalarons. The parameter $f_{SP}$ measuring deviation from Schwarzschild pericenter shift has been found as $f_{SP}=1.00-1.04$ within stellar orbits having semi-major axes $45$ au - $100$ au. Scalarons have the capability to dominate Schwarzschild precession for orbits much below $45$ au. Lense-Thirring (LT) precession with the new metric is estimated for the compact orbits. The massive scalarons produce LT precession with magnitude ($12.25-24.5$) $μ$as/yr in the orbit of S2. The LT precession time scale is within $0.1$% of the age of the S-stars.

description: In this paper we consider the relationship between order and topology in the vector lattice $C_b(X)$ of all bounded continuous functions on a Hausdorff space $X$. We prove that the restriction of $f\in C_b(X)$ to a closed set $A$ induces an order continuous operator iff $A=\overline{\mathrm{Int} A}.$ This result enables us to easily characterize bands and projection bands in $C_0(X)$ and $C_b(X)$ through the one-point compactification and the Stone-Čech compactification of $X$, respectively. With these characterizations we describe order complete $C_0(X)$ and $C_b(X)$-spaces in terms of extremally disconnected spaces. Our results serve us to solve an open question on lifting un-convergence in the case of $C_0(X)$ and $C_b(X)$.

We couple the ladder to two baths at different temperatures and chemical potentials and analyze the efficiency and power generated in the linear as well as nonlinear response regime. Our results, obtained with the Green's function method, show that the maximum performance efficiency and generated power are strongly dependent on the type of the underlying energy spectrum. We also show that the ideal scenario for efficient energy conversion, as well as power generation, corresponds to the case in which the spectrum has a gap between the bands, and the ground state is degenerate.

description: International food trade plays an important role in food security, but little research has been devoted to studying crop dynamics in importing countries caused by trade. We studied the spatiotemporal patterns of soybean planting area in China (the largest soybean importing country) in response to soybean imports. The results show how the soybean planting area from 1980 to 2012 in China is dominated by two temporal patterns, both of which first increased, then decreased, with an 8-year time lag. The first increasing-decreasing pattern is affected by increasing soybean imports, and the second increasing-decreasing pattern is driven by decreasing domestic soybean profits. The results also show spatially distinct spatial patterns: soybean planting area decreased in southeastern China while it increased in northwestern China. Our analysis of soybean planting area helps China and other food-importing countries understand spatiotemporal responses of domestic agricultural cultivations caused by international food trade and agricultural pollution management.

Recently, IoT technologies have been progressed but in the healthcare area, real-time actions based on analyzed vital data are not considered sufficiently yet. The causes are proper use of analyzing methods of stream / micro batch processing and network cost. To resolve existing problems, we propose our vital data analysis platform. Our platform collects vital data of Electrocardiograph and acceleration using an example of wearable vital sensor and analyzes them to extract posture, fatigue and relaxation in smart phones or cloud. Our platform can show analyzed dangerous posture or fatigue level change. We implemented the platform. And we are now preparing a field test.

description: Here we present an in-depth study of the behaviour of the Fast Folding Algorithm, an alternative pulsar searching technique to the Fast Fourier Transform. Weaknesses in the Fast Fourier Transform, including a susceptibility to red noise, leave it insensitive to pulsars with long rotational periods (P > 1 s). This sensitivity gap has the potential to bias our understanding of the period distribution of the pulsar population. The Fast Folding Algorithm, a time-domain based pulsar searching technique, has the potential to overcome some of these biases. Modern distributed-computing frameworks now allow for the application of this algorithm to all-sky blind pulsar surveys for the first time. However, many aspects of the behaviour of this search technique remain poorly understood, including its responsiveness to variations in pulse shape and the presence of red noise. Using a custom CPU-based implementation of the Fast Folding Algorithm, ffancy, we have conducted an in-depth study into the behaviour of the Fast Folding Algorithm in both an ideal, white noise regime as well as a trial on observational data from the HTRU-S Low Latitude pulsar survey, including a comparison to the behaviour of the Fast Fourier Transform. We are able to both confirm and expand upon earlier studies that demonstrate the ability of the Fast Folding Algorithm to outperform the Fast Fourier Transform under ideal white noise conditions, and demonstrate a significant improvement in sensitivity to long-period pulsars in real observational data through the use of the Fast Folding Algorithm.

description: We study the emergence of quasiperiodic Bloch wave functions in quasicrystals, employing the one-dimensional Fibonacci model as a test case. We find that despite the fact that Bloch functions are not eigenfunctions themselves, superpositions of relatively small numbers of nearly degenerate eigenfunctions give rise to extended quasiperiodic Bloch functions. These functions possess the structure of earlier ancestors of the underlying Fibonacci potential, and it is often possible to obtain different ancestors as different superpositions around the same energy. There exists an effective crystal momentum that characterizes these ancestors, which is determined by the mean energy of the superimposed eigenfunctions, giving rise to an effective dispersion curve. We also find that quasiperiodic Bloch functions do emerge as eigenfunctions when weak disorder is introduced into the otherwise perfect quasiperiodic potential. These theoretical results may explain a number of experimental observations, and may have practical consequences on emerging theories of band topology and correlated electrons in quasicrystals.

We show that a multiset of $2 \cdot (2^n-1)^2$ EA-equivalence classes of such restrictions defines an EA-invariant for vectorial Boolean functions on $\mathbb{F}_2^n$. Further, for all of the known quadratic APN functions in dimension $n < 10$, we determine the restrictions that are also APN. Moreover, we construct 6,368 new quadratic APN functions in dimension eight up to EA-equivalence by extending a quadratic APN function in dimension seven. A special focus of this work is on quadratic APN functions with maximum linearity. In particular, we characterize a quadratic APN function $F \colon \mathbb{F}_2^n \rightarrow \mathbb{F}_2^n$ with linearity of $2^{n-1}$ by a property of the ortho-derivative of its restriction to a linear hyperplane. Using the fact that all quadratic APN functions in dimension seven are classified, we are able to obtain a classification of all quadratic 8-bit APN functions with linearity $2^7$ up to EA-equivalence.

description: The circadian rhythm of blood pressure (BP) is believed to be regulated by the clock system, which is closely linked to levels of angiotensin II (Ang II). This study aimed to investigate whether Ang II mediates the proliferation of vascular smooth muscle cells (VSMCs) through the interaction between the clock system and the mitogen-activated protein kinase (MAPK) signaling pathway. Primary rat aortic VSMCs were treated with Ang II, with or without MAPK inhibitors. VSMC proliferation, expression of clock genes, CYCLIN E, and MAPK pathways were assessed. Ang II treatment resulted in increased VSMC proliferation and rapid upregulation of clock gene Periods (Pers) expression. Compared to the non-diseased control (NC) group, VSMCs incubated with Ang II displayed a noticeable delay in the G1/S phase transition and downregulation of CYCLIN E upon silencing of Per1 and Per2 genes. Importantly, silencing Per1 or Per2 in VSMCs led to decreased expression of key MAPK pathway proteins, including RAS, phosphorylated mitogen-activated protein kinase (P-MEK), and phosphorylated extracellular signal-regulated protein kinase (P-ERK). Moreover, the MEK and ERK inhibitors, U0126 and SCH772986, significantly attenuated the Ang II-induced proliferation of VSMCs, as evidenced by an increased G1/S phase transition and decreased CYCLIN E expression. The MAPK pathway plays a critical role in regulating VSMC proliferation in response to Ang II stimulation. This regulation is controlled by the expression of circadian clock genes involved in the cell cycle. These findings provide novel insights for further research on diseases associated with abnormal VSMC proliferation.

description: The goal of this article is to provide an useful criterion of positivity and well-posedness for a wide range of infinite dimensional semilinear abstract Cauchy problems. This criterion is based on some weak assumptions on the non-linear part of the semilinear problem and on the existence of a strongly continuous semigroup generated by the differential operator. To illustrate a large variety of applications, we exhibit the feasibility of this criterion through three examples in mathematical biology: epidemiology, predator-prey interactions and oncology.

Beyond Traditional Models: Multi-Stakeholder Cooperatives and their Differential Roles

description: The multi-stakeholder cooperative emerges as an innovative organization departing from the traditional single-stakeholder consumer and producer models. The multi-stakeholding approach aims at broadening the scope of those who have a strong stake in the cooperative's success. This, however, is not necessarily related to the notion of membership. This article develops this point drawing upon two distinct cases: on the one -hand the "hybrid" cooperative, characterized by the figure of the external investor and, on the other hand, the newly emerging multi-stakeholder cooperatives characterized by a strong community and social alternative orientation. It is argued that the two organizational types widely differ as to their short-term objectives and broader implications. Further to a theoretical introduction, practical examples illustrate the differential roles of both types at a time of growing market competition.
Breaking Symmetries Leads to Diverse Quadrupedal Gaits

description: Symmetry manifests itself in legged locomotion in a variety of ways. No matter where a legged system begins to move periodically, the torso and limbs coordinate with each other's movements in a similar manner. Also, in many gaits observed in nature, the legs on both sides of the torso move in exactly the same way, sometimes they are just half a period out of phase. Furthermore, when some animals move forward and backward, their movements are strikingly similar as if the time had been reversed. This work aims to generalize these phenomena and propose formal definitions of symmetries in legged locomotion using group theory terminology. Symmetries in some common quadrupedal gaits such as pronking, bounding, half-bounding, and galloping have been discussed. Moreover, a spring-mass model has been used to demonstrate how breaking symmetries can alter gaits in a legged system. Studying the symmetries may provide insight into which gaits may be suitable for a particular robotic design, or may enable roboticists to design more agile and efficient robot controllers by using certain gaits.

Iterative Filter Adaptive Network for Single Image Defocus Deblurring

description: We propose a novel end-to-end learning-based approach for single image defocus deblurring. The proposed approach is equipped with a novel Iterative Filter Adaptive Network (IFAN) that is specifically designed to handle spatially-varying and large defocus blur. For adaptively handling spatially-varying blur, IFAN predicts pixel-wise deblurring filters, which are applied to defocused features of an input image to generate deblurred features. For effectively managing large blur, IFAN models deblurring filters as stacks of small-sized separable filters. Predicted separable deblurring filters are applied to defocused features using a novel Iterative Adaptive Convolution (IAC) layer. We also propose a training scheme based on defocus disparity estimation and reblurring, which significantly boosts the deblurring quality. We demonstrate that our method achieves state-of-the-art performance both quantitatively and qualitatively on real-world images.

description: In this work, we highlight how trapped-ion quantum systems can be used to study generalized Holstein models, and benchmark expensive numerical calculations. We study a particular spin-Holstein model that can be implemented with arrays of ions confined by individual microtraps, and that is closely related to the Holstein model of condensed matter physics, used to describe electron-phonon interactions. In contrast to earlier proposals, we focus on simulating many-electron systems and inspect the competition between charge-density wave order, fermion pairing and phase separation. In our numerical study, we employ a combination of complementary approaches, based on non-Gaussian variational ansatz states and matrix product states, respectively. We demonstrate that this hybrid approach outperforms standard density-matrix renormalization group calculations.

description: The motion of energetic particles in magnetic turbulence across a mean magnetic field is explored analytically. The approach presented here allows for a full time-dependent description of the transport, including compound sub-diffusion. The first time it is shown systematically that as soon as there is transverse structure of the turbulence, diffusion is restored even if no Coulomb collisions are invoked. Criteria for sub-diffusion and normal Markovian diffusion are found as well.

description: One of the most important challenges in antiferromagnetic spintronics is the read-out of the Néel vector state. High current densities up to 10$^8$ Acm$^{-2}$ used in the electrical switching experiments cause notorious difficulty in distinguishing between magnetic and thermal origins of the electrical signals. To overcome this problem, we present a temperature dependence study of the transverse resistance changes in the switching experiment with CoO|Pt devices. We demonstrate the possibility to extract a pattern of spin Hall magnetoresistance for current pulses density of $5 \times 10^7$ Acm$^{-2}$ that is present only below the Néel temperature and does not follow a trend expected for thermal effects. This is the compelling evidence for the magnetic origin of the signal, which is observed using purely electrical techniques. We confirm these findings by complementary experiments in an external magnetic field. Such an approach can allow determining the optimal conditions for switching antiferromagnets and be very valuable when no imaging techniques can be applied to verify the origin of the electrical signal.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.
