description: We study statistical calibration, i.e., adjusting features of a computational model that are not observable or controllable in its associated physical system. We focus on functional calibration, which arises in many manufacturing processes where the unobservable features, called calibration variables, are a function of the input variables. A major challenge in many applications is that computational models are expensive and can only be evaluated a limited number of times. Furthermore, without making strong assumptions, the calibration variables are not identifiable. We propose Bayesian non-isometric matching calibration (BNMC) that allows calibration of expensive computational models with only a limited number of samples taken from a computational model and its associated physical system. BNMC replaces the computational model with a dynamic Gaussian process (GP) whose parameters are trained in the calibration procedure. To resolve the identifiability issue, we present the calibration problem from a geometric perspective of non-isometric curve to surface matching, which enables us to take advantage of combinatorial optimization techniques to extract necessary information for constructing prior distributions. Our numerical experiments demonstrate that in terms of prediction accuracy BNMC outperforms, or is comparable to, other existing calibration frameworks.

description: In this paper we present spin-to-charge current conversion properties in the Weyl semimetal TaP by means of the inverse Rashba-Edelstein effect (IREE) with the integration of this quantum material with the ferromagnetic metal Permalloy $(Py=Ni_{81}Fe_{19})$. The spin currents are generated in the Py layer by the spin pumping effect (SPE) from microwave-driven ferromagnetic resonance and are detected by a dc voltage along the TaP crystal, at room temperature. We observe a field-symmetric voltage signal without the contamination of asymmetrical lines due to spin rectification effects observed in studies using metallic ferromagnets. The observed voltage is attributed to spin-to-charge current conversion based on the IREE, made possible by the spin-orbit coupling induced intrinsically by the bulk band structure of Weyl semimetals. The measured IREE coefficient $λ_{IREE}=(0.30 \pm{0.01})$ nm is two orders of magnitude larger than in graphene and is comparable to or larger than the values reported for some metallic interfaces and for several topological insulators.

Overview

 

Después de la caída de la Unión Soviética y la debacle económica con Boris Yeltsin, Vladimir Putin se afianzó como un actor político imprescindible en el panorama ruso, dispuesto a continuar la apertura económica y permitir el enriquecimiento de una corrupta élite empresaria, a condición de que no se interpusiera en su fulgurante ascenso político. También dio rienda suelta al expansionismo, origen de dos de las guerras más sangrientas (y menos conocidas) del último tiempo: Chechenia y el Donbass.El mundo fue testigo del nacimiento de un nuevo tipo de líder. Antes que Donald Trump, antes que Jair Bolsonaro, Putin inauguró una manera irreverente, soez, casi impropia de manejarse ante la prensa (y el mundo). Desde que Putin ascendió a lo más alto del poder de su país, tuvieron lugar tragedias que pusieron a Rusia en el centro de las noticias de política internacional: el hundimiento del submarino Kursk, las masacres del teatro de Moscú y la escuela de Beslán, los asesinatos de la periodista Anna Politkovskaya y el exespía Aleksandr Litvinenko. Fueron también los años de la disolución del modo de vida comunista y el impactante surgimiento de un puñado de oligarcas rusos, figuras intermedias entre el Estado y las mafias; de la multiplicación de crímenes contra todo aquel dispuesto a expresar su disenso. También, de la criminalización de la diversidad sexual.Rusos de Putin es un viaje a las profundidades de un país vasto y complejo, que de la mano de este político carismático recuperó su orgullo nacional. Con el aguzado mirar de una investigadora privada, Hinde Pomeraniec visitó Moscú, San Petersburgo, Londres, buscando las razones detrás del ascenso rutilante de un ignoto espía que se convirtió en el líder que Occidente impugna. Gracias a los oficios de intérpretes, habló con testigos directos, recorrió los lugares y observó cada detalle de la nueva Rusia. El resultado es esta crónica apasionante y desprejuiciada, donde conviven la compasión y el temor, el drama y la farsa en una prosa personalísima. Un libro para entender la convulsionada historia y actualidad de un país del tamaño de un continente.

description: AbstractBACKGROUND & AIMS: To investigate whether mitogen-activated protein kinase (MAPK) cascades might play a role in the progression of colon cancer, c-Jun N-terminal kinase (JNK) and extracellular signal regulating kinase (ERK) activity during colonic tumorigenesis were examined.METHODS: The 1,2-dimethylhydrazine (DMH)-induced colon carcinoma model was used to study the activation of these kinases during intestinal carcinogenesis. Male Sprague-Dawley rats were injected with DMH for 24 weeks. Normal-appearing intestinal mucosa from control and treated animals and DMH-induced intestinal tumors were assayed for JNK and ERK activity using solid phase in vitro kinase assays. Tumors were typed for mutations in the K-ras gene.RESULTS: There was little or no difference in JNK and ERK activity in hyperproliferative mucosa from DMH-treated animals compared with normal mucosa from control animals. However, in 16 colonic neoplasms, an average of 23-fold and 29-fold increases in JNK and ERK activities were observed, respectively, over control levels. In addition, activating protein-1 binding was strongly induced in the colonic tumors. Activation did not correlate with the presence of mutations in K-ras.CONCLUSIONS: Both the JNK and ERK MAPKs are highly activated during late progression of colorectal carcinoma. This change is dependent on the tumorigenic state rather than changes in proliferation.(Gastroenterology 1997 Nov;113(5):1589-98)

description: Spider orb webs are multifunctional, acting to absorb prey impact energy and transmit vibratory information to the spider. This paper explores the links between silk material properties, propagation of vibrations within webs and the ability of the spider to control and balance web function. Combining experimental and modelling approaches, we contrast transverse and longitudinal wave propagation in the web. It emerged that both transverse and longitudinal wave amplitude in the web can be adjusted through changes in web tension and dragline silk stiffness, i.e. properties, which can be controlled by the spider. In particular, we propose that dragline silk supercontraction may have evolved as a control mechanism for these multifunctional fibres. The various degrees of active influence on web engineering reveals the extraordinary ability of spiders to shape the physical properties of their self-made materials and architectures to affect biological functionality, balancing trade-offs between structural and sensory functions.

description: Electroless nickel plating is an established industrial process that provides a robust and relatively low-cost coating suitable for transporting and storing ultracold neutrons (UCN). Using roughness measurements and UCN-storage experiments we characterized UCN guides made from polished aluminum or stainless-steel tubes plated by several vendors. All electroless nickel platings were similarly suited for UCN storage with an average loss probability per wall bounce of $2.8\cdot10^{-4}$ to $4.1\cdot10^{-4}$ for energies between 90 neV and 190 neV, or a ratio of imaginary to real Fermi potential $η$ of $1.7\cdot10^{-4}$ to $3.3\cdot10^{-4}$. Measurements at different elevations indicate that the energy dependence of UCN losses is well described by the imaginary Fermi potential. Some special considerations are required to avoid an increase in surface roughness during the plating process and hence a reduction in UCN transmission. Increased roughness had only a minor impact on storage properties. Based on these findings we chose a vendor to plate the UCN-production vessel that will contain the superfluid-helium converter for the new TRIUMF UltraCold Advanced Neutron (TUCAN) source, achieving acceptable UCN-storage properties with ${η=3.5(5)\cdot10^{-4}}$.

description: We consider backward vector meson exclusive electroproduction off nucleons in the framework of collinear QCD factorization. Nucleon to vector meson transition distribution amplitudes arise as building blocks for the corresponding factorized amplitudes. In the near-backward kinematics, the suggested factorization mechanism results in the dominance of the transverse cross section of vector meson production ($σ_T \gg σ_L$) and in the characteristic $1/Q^8$-scaling behavior of the cross section. We evaluate nucleon to vector meson TDAs in the cross-channel nucleon exchange model and present estimates of the differential cross section for backward $ρ^0$, $ω$ and $ϕ$ meson production off protons. The resulting cross sections are shown to be measurable in the forthcoming JLab@12 GeV experiments.

Is rectal pain sensitivity a biological marker for irritable bowel syndrome: Psychological influences on pain perception
Creators: name: Palsson, O. S.
name: Whitehead, W. E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1998

description: AbstractBackground & Aims: Rectal pain sensitivity has been called a biological marker for irritable bowel syndrome, but this conclusion may be premature. This article is a critical review of the evidence for psychological influences on perception. Methods: The world literature accessible through Index Medicus from 1973 to 1997 was systematically reviewed. Results: Evidence favoring a biological basis for pain sensitivity is that two thirds of patients report pain at abnormally low thresholds of rectal distention despite normal somatic pain thresholds. Pain thresholds are not correlated with anxiety or depression. Evidence favoring psychological influences on perception is that patients with the irritable bowel syndrome rate even sham distentions as more painful, and when perception tests that minimize psychological influences are used, they have normal sensory thresholds. Also, stress alters sensory thresholds. Sensitization by repeated distention has been cited as evidence of a biological basis for hyperalgesia, but it is not unique to patients with irritable bowel. Brain imaging shows that different regions are activated by painful distention in patients with irritable bowel syndrome, but this is consistent with psychological influences on perception. Conclusions: Psychological factors influence pain thresholds in patients with the irritable bowel syndrome. Two cognitive traits, selective attention to gastrointestinal sensations and disease attribution, may account for increased pain sensitivity.GASTROENTEROLOGY 1998;115:1263-1271

description: 2D materials are expected to be favorable channel materials for field-effect transistor (FET) with extremely short channel length because of their superior immunity to short-channel effects (SCE). Graphene, which is the most famous 2D material, has no bandgap without additional techniques and this property is major hindrance in reducing the drain leakage. Therefore, 2D materials with finite band gap, such as transition metal dichalcogenides (TMDs, e.g. MoS2 WSe2) or phosphorene, are required for the low power consumption FETs. Hafnium disulfide (HfS2) is a novel TMD, which has not been investigated as channel material. We focused on its potential for well-balanced mobility and bandgap properties. The higher electron affinity of Hf dichalcogenides compared with Mo or W chalcogenides facilitates the formation of low resistance contact and staggered heterojunction with other 2D materials. Here we demonstrate the first few layer HfS2 FET with robust current saturation and high current on/off ratio of more than 10^4.

description: Few-shot Class-Incremental Learning (FSCIL) aims at learning new concepts continually with only a few samples, which is prone to suffer the catastrophic forgetting and overfitting problems. The inaccessibility of old classes and the scarcity of the novel samples make it formidable to realize the trade-off between retaining old knowledge and learning novel concepts. Inspired by that different models memorize different knowledge when learning novel concepts, we propose a Memorizing Complementation Network (MCNet) to ensemble multiple models that complements the different memorized knowledge with each other in novel tasks. Additionally, to update the model with few novel samples, we develop a Prototype Smoothing Hard-mining Triplet (PSHT) loss to push the novel samples away from not only each other in current task but also the old distribution. Extensive experiments on three benchmark datasets, e.g., CIFAR100, miniImageNet and CUB200, have demonstrated the superiority of our proposed method.

Oncogenic ras induces gastrin gene expression in colon cancer

description: AbstractBackground & Aims: The expression of gastrin, as a tumor growth factor, is significantly increased in some colon cancers compared with the low levels found in normal mucosa. The aim of this study was to elucidate the transcriptional mechanisms of gastrin induction in colon cancer. Methods: Gastrin messenger (mRNA) levels and K-ras genotype were determined in colon cancer cell lines and surgical specimens. Colon cancer cells were transfected with oncogenic ras expression vectors, and transcriptional activity was assayed with gastrin-luciferase reporter genes. Results: Colon cancer cell lines and tissues with K-ras mutations all had significantly higher gastrin mRNA levels than those that were ras wild type. Treatment of several ras mutant cell lines with PD98059, an inhibitor of mitogen-activated protein kinase kinase, resulted in a decrease in endogenous gastrin mRNA levels. The effects of ras on gastrin expression appeared to be mediated through the gastrin promoter because transfection of oncogenic ras and activated raf expression vectors both induced gastrin-promoter, luciferase-reporter genes. The inductive effects of oncogenic ras could be blocked by the coexpression of dominant negative forms of raf and extracellular regulated kinase. Conclusions: Oncogenic ras induces gastrin gene expression through activation of the Raf-MEK-ERK signal transduction pathway.GASTROENTEROLOGY 1998;115:1144-1153

description: In recent years, there has been an exponential growth of applications, including dialogue systems, that handle sensitive personal information. This has brought to light the extremely important issue of personal data protection in virtual environments. Sensitive Information Detection (SID) approaches different domains and languages in literature. However, if we refer to the personal data domain, a shared benchmark or the absence of an available labeled resource makes comparison with the state-of-the-art difficult. We introduce and release SPeDaC , a new annotated resource for the identification of sensitive personal data categories in the English language. SPeDaC enables the evaluation of computational models for three different SID subtasks with increasing levels of complexity. SPeDaC 1 regards binary classification, a model has to detect if a sentence contains sensitive information or not; whereas, in SPeDaC 2 we collected labeled sentences using 5 categories that relate to macro-domains of personal information; in SPeDaC 3, the labeling is fine-grained (61 personal data categories). We conduct an extensive evaluation of the resource using different state-of-the-art-classifiers. The results show that SPeDaC is challenging, particularly with regard to fine-grained classification. The transformer models achieve the best results (acc. RoBERTa on SPeDaC 1 = 98.20%, DeBERTa on SPeDaC 2 = 95.81% and SPeDaC 3 = 77.63%).

Investigating the jettability of toluene in a piezo inkjet

description: This report starts by introducing the working principles of a single nozzle piezo inkjet system. The current voltage waveform calibration process for a piezo inkjet is time consuming and subsequently a cause for material waste. Recent research has demonstrated that the use of real-time imaging of in-flight drops integrated with genetic algorithms (GAs) can lead to improved waveforms that provide enhanced system performance. In this work, the same imaging system is used to reproduce known results for simple fluids such as water, and manual waveform tuning was used instead. This framework was then extended to nonpolar solvents. The experiments presented in this project investigated the jettability of toluene. Toluene is a nonpolar liquid that has raised interest about its viability as an ink used in piezo inkjets. The manual waveform tuning process was centered around adjusting key parameters such as dwell time and dwell voltage. As these parameters were tweaked, real-time imaging was used to observe the drop formation at the orifice of the inkjet nozzle. Once the key parameters were optimized, a droplet of toluene was generated. Unipolar, bipolar, and tripolar actuation waveforms were investigated to determine if a droplet of toluene was able to be dispensed. Bipolar and tripolar waveforms produced droplets that were dispensed at irregular frequencies along with physical deformities. This work found that using a unipolar actuation waveform produced the best results, generating consistent spherical toluene droplets with an average drop volume of 30.2 pL. The optimal waveform parameters were as follows: a rise time of 11 µs, a dwell time of 36 µs, a fall time of 9 µs, and a dwell voltage of 60 V.

description: AbstractBackground & Aims: Recent data support an important role of resident luminal bacteria in experimental colitis. We determined how altered cecal bacterial loads influence colitis and gastritis. Methods: A cecal self-filling blind loop (SFBL) was created or the cecum was excluded from the fecal stream in specific pathogen–free HLA-B27 transgenic (TG) rats with early colitis and in nontransgenic (nonTG) littermates; controls underwent sham operation (SHAM). Luminal bacterial concentrations were determined by culture and counting chamber. Results: TG rats with SFBL had more severe cecal inflammation and leukocytosis than TG SHAM controls. TG excluded rats with low cecal bacterial loads had no cecal inflammation and less colitis and gastritis than SHAM controls, despite having normal distal colonic and gastric bacterial concentrations. Metronidazole attenuated cecal inflammation and eliminated Bacteroides in SFBL TG rats. NonTG SFBL rats had mild cecal inflammation and no gastritis and colitis. The ratio of total anaerobic to aerobic bacteria was 1000-fold greater in SFBL than in SHAM rats, with a 10,000-fold increased ratio of Bacteroides spp. to aerobes. Conclusions: The luminal bacterial load and composition determines the activity of cecal inflammation in genetically susceptible hosts. Lowering cecal bacterial concentrations can diminish inflammation in remote organs.GASTROENTEROLOGY 1999;116:310-319
Transport of secondary electrons and reactive species in ion tracks

Year: 2015
Subjects: subject: Biological Physics (physics.bio-ph)

description: The transport of reactive species brought about by ions traversing tissue-like medium is analysed analytically. Secondary electrons ejected by ions are capable of ionizing other molecules; the transport of these generations of electrons is studied using the random walk approximation until these electrons remain ballistic. Then, the distribution of solvated electrons produced as a result of interaction of low-energy electrons with water molecules is obtained. The radial distribution of energy loss by ions and secondary electrons to the medium yields the initial radial dose distribution, which can be used as initial conditions for the predicted shock waves. The formation, diffusion, and chemical evolution of hydroxyl radicals in liquid water are studied as well.

description: A number of recent works have argued that quantum complexity, a well-known concept in computer science that has re-emerged recently in the context of the physics of black holes, may be used as an efficient probe of novel phenomena such as quantum chaos and even quantum phase transitions. In this article, we provide further support for the latter, using a 1-dimensional p-wave superconductor - the Kitaev chain - as a prototype of a system displaying a topological phase transition. The Hamiltonian of the Kitaev chain manifests two gapped phases of matter with fermion parity symmetry; a trivial strongly-coupled phase and a topologically non-trivial, weakly-coupled phase with Majorana zero-modes. We show that Krylov-complexity (or, more precisely, the associated spread-complexity) is able to distinguish between the two and provides a diagnostic of the quantum critical point that separates them. We also comment on some possible ambiguity in the existing literature on the sensitivity of different measures of complexity to topological phase transitions.

Magnetic wormholes and black universes with invisible ghosts

description: We construct explicit examples of globally regular static, spherically symmetric solutions in general relativity with scalar and electromagnetic fields describing traversable wormholes with flat and AdS asymptotics and regular black holes, in particular, black universes. (A black universe is a regular black hole with an expanding, asymptotically isotropic space-time beyond the horizon.) The existence of such objects requires invoking scalars with negative kinetic energy ("phantoms", or "ghosts"), which are not observed under usual physical conditions. To account for that, the so-called "trapped ghosts" were previously introduced, i.e., scalars whose kinetic energy is only negative in a restricted strong-field region of space-time and positive outside it. This approach leads to certain problems, including instability (as is illustrated here by derivation of an effective potential for spherical pertubations of such systems). In this paper, we use for model construction what we call "invisible ghosts", i.e., phantom scalar fields sufficiently rapidly decaying in the weak-field region. The resulting configurations contain different numbers of Killing horizons, from zero to four.

description: Spider orb webs are multifunctional, acting to absorb prey impact energy and transmit vibratory information to the spider. This paper explores the links between silk material properties, propagation of vibrations within webs and the ability of the spider to control and balance web function. Combining experimental and modelling approaches, we contrast transverse and longitudinal wave propagation in the web. It emerged that both transverse and longitudinal wave amplitude in the web can be adjusted through changes in web tension and dragline silk stiffness, i.e. properties, which can be controlled by the spider. In particular, we propose that dragline silk supercontraction may have evolved as a control mechanism for these multifunctional fibres. The various degrees of active influence on web engineering reveals the extraordinary ability of spiders to shape the physical properties of their self-made materials and architectures to affect biological functionality, balancing trade-offs between structural and sensory functions.
DE0823$-$49 is a juvenile binary brown dwarf at 20.7 pc

description: Astrometric monitoring of the nearby early-L dwarf DE0823$-$49 has revealed a low-mass companion in a 248-day orbit that was announced in an earlier work. Here, we present new astrometric and spectroscopic observations that allow us to characterise the system in detail. The optical spectrum shows LiI-absorption indicative of a young age and/or substellar mass for the primary component. The near-infrared spectrum is best reproduced by a binary system of brown dwarfs with spectral types of L1.5 $+$ L5.5 and effective temperatures of $2150\pm100$ K and $1670\pm140$ K. To conform with the photocentric orbit size measured with astrometry and the current understanding of substellar evolution, the system must have an age in the 80--500 Myr range. Evolutionary models predict component masses in the ranges of $M_1\simeq0.028-0.063\,M_\odot$ and $M_2\simeq0.018-0.045\,M_\odot$ with a mass ratio of $q\simeq0.64-0.74$. Multi-epoch radial velocity measurements unambiguously establish the three-dimensional orbit of the system and allow us to investigate its kinematic properties. DE0823$-$49 emerges as a rare example of a nearby brown dwarf binary with orbit, component properties, and age that are characterised well. It is a juvenile resident of the solar neighbourhood, but does not appear to belong to a known young association or moving group.

description: We revisit the constraint from the recently reported cosmic birefringence on axion-like particles with a general decay constant. A particular attention is paid to the naturalness of the model parameter space, which has been overlooked in the literature. We show that the observed cosmic birefringence is naturally explained by the electroweak axion with a string-theory inspired decay constant $F_A\simeq 10^{16}$ GeV.

description: AbstractBackground & Aims: Infectious diarrhea caused by viruses plus enterotoxigenic bacteria is often more severe than diarrhea induced by either pathogen alone. We postulated that the increased cell adenosine 3',5'-cyclic monophosphate (cAMP) concentration observed during infection by enterotoxigenic organisms retards the intestinal repair process by blocking activation of mitogen-activated protein kinases (MAPKs) in proliferating intestinal cells. Methods: We evaluated the effects of glutamine on MAPK activity, thymidine incorporation, and cell number in glutamine-starved and -sufficient rat intestinal crypt cells (IEC-6). Results: In glutamine-starved cells, 10 mmol/L glutamine in the absence of serum stimulated [3H]thymidine incorporation 8-fold. This effect was inhibited by 60% with 8-(4-chlorophenylthio) (8-CPT)-cAMP (100 μmol/L) + isobutyl methylxanthine (100 μmol/L). In cells not starved of glutamine, glutamine stimulated thymidine incorporation by 3-fold, and 8-CPT-cAMP completely blocked the mitogenic effect. Inhibition of proliferation by cAMP persisted for at least 68 hours after cAMP removal. In vitro kinase assays showed that glutamine signaling requires an intact ERK (extracellular signal–related kinase) pathway in unstarved cells. In starved cells, at least one other pathway (JNK) was activated by glutamine, and the mitogenic inhibition by 8-CPT-cAMP was incomplete. Other intestinal fuels (glucose and acetate) were not mitogenic. Conclusions: Increased levels of intracellular cAMP inhibit ERKs but only partially reduce glutamine-stimulated proliferation in enterocytes adapted to low glutamine.GASTROENTEROLOGY 2000;118:90-100
