description: Block polymers dispersed into a solvent that prefers one block strongly over the other blocks can spontaneously arrange into nanoscale structures, such as spherical or cylindrical micelles. These nanoscale structures can pack into three dimensional crystalline grains. The final properties of a material with crystalline nanostructure are dependent on many factors including the thermal and shear history of the sample. Any additional components to the system may change the nanoscale structure which will consequently change the final mechanical properties. In this work a practical understanding of block polymer phases is established, along with useful processing techniques. Widely accessible rheological techniques are used to demonstrate a unique fingerprint between FCC and BCC crystalline phases. We then demonstrate the importance of shear processing by using large amplitude oscillatory shear to accelerate a crystalline order transition to occur within minutes rather than months. The mobility of proteins through the aqueous channels in block polymer crystals is quantified with a semiautonomous Fluorescence Recovery After Photobleaching microscope built for this work. The outcome of this work is a set of guiding principles to allow for systematic design of a material with a crystalline block polymer structure.

description: To date, high-resolution (< 1 nm) imaging of extended objects in three-dimensions (3D) has not been possible. A restriction known as the Crowther criterion forces a tradeoff between object size and resolution for 3D reconstructions by tomography. Further, the sub-Angstrom resolution of aberration-corrected electron microscopes is accompanied by a greatly diminished depth of field, causing regions of larger specimens (> 6 nm) to appear blurred or missing. Here we demonstrate a three-dimensional imaging method that overcomes both these limits by combining through-focal depth sectioning and traditional tilt-series tomography to reconstruct extended objects, with high-resolution, in all three dimensions. The large convergence angle in aberration corrected instruments now becomes a benefit and not a hindrance to higher quality reconstructions. A through-focal reconstruction over a 390 nm 3D carbon support containing over one hundred dealloyed and nanoporous PtCu catalyst particles revealed with sub-nanometer detail the extensive and connected interior pore structure that is created by the dealloying instability.

description: We present a theoretical study of the optical angular momentum transfer from a circularly polarized plane wave to thin metal nanoparticles of different rotational symmetries. While absorption has been regarded as the predominant mechanism of torque generation on the nanoscale, we demonstrate numerically how the contribution from scattering can be enhanced by using multipolar plasmon resonance. The multipolar modes in non-circular particles can convert the angular momentum carried by the scattered field, thereby producing scattering-dominant optical torque, while a circularly symmetric particle cannot. Our results show that the optical torque induced by resonant scattering can contribute to 80% of the total optical torque in gold particles. This scattering-dominant torque generation is extremely mode-specific, and deserves to be distinguished from the absorption-dominant mechanism. Our findings might have applications in optical manipulation on the nanoscale as well as new designs in plasmonics and metamaterials.

description: In the framework of the Herschel/PRISMAS Guaranteed Time Key Program, the line of sight to the distant ultracompact HII region W51e2 has been observed using several selected molecular species. Most of the detected absorption features are not associated with the background high-mass star-forming region and probe the diffuse matter along the line of sight. We present here the detection of an additional narrow absorption feature at ~70 km/s in the observed spectra of HDO, NH3 and C3. The 70 km/s feature is not uniquely identifiable with the dynamic components (the main cloud and the large-scale foreground filament) so-far identified toward this region. The narrow absorption feature is similar to the one found toward low-mass protostars, which is characteristic of the presence of a cold external envelope. The far-infrared spectroscopic data were combined with existing ground-based observations of 12CO, 13CO, CCH, CN, and C3H2 to characterize the 70 km/s component. Using a non-LTE analysis of multiple transitions of NH3 and CN, we estimated the density (n(H2) (1-5)x10^5 cm^-3) and temperature (10-30 K) for this narrow feature. We used a gas-grain warm-up based chemical model with physical parameters derived from the NH3 data to explain the observed abundances of the different chemical species. We propose that the 70 km/s narrow feature arises in a dense and cold clump that probably is undergoing collapse to form a low-mass protostar, formed on the trailing side of the high-velocity filament, which is thought to be interacting with the W51 main cloud. While the fortuitous coincidence of the dense clump along the line of sight with the continuum-bright W51e2 compact HII region has contributed to its non-detection in the continuum images, this same attribute makes it an appropriate source for absorption studies and in particular for ice studies of star-forming regions.

description: Previous papers have described a computational approach to System of Systems (SoS) development using an Agent-Based Model (ABM). This paper describes the Fuzzy Decision Analysis used in the negotiation between the SoS agent and a System agent in the ABM of an Acknowledged SoS development. An Acknowledged SoS has by definition a limited influence on the development of the individual Systems. The individual Systems have their own priorities, pressures, and agenda which may or may not align with the goals of the SoS. The SoS has some funding and deadlines which can be used to negotiate with the individual System in order to illicit the required capability from that System. The Fuzzy Decision Analysis determines how the SoS agent will adjust the funding and deadlines for each of the Systems in order to achieve the desired SoS architecture quality. The Fuzzy Decision Analysis has inputs of performance, funding, and deadlines as well as weights for each capability. The performance, funding, and deadlines are crisp values which are fuzzified. The fuzzified values are then used with a Fuzzy Inference Engine to get the fuzzy outputs of funding adjustment and deadline adjustment which must then be defuzzified before being passed to the System agent. The first contribution of this paper is the fuzzy decision analysis that represents the negotiation between the SoS agent and the System agent. A second contribution of this paper is the method of implementing the fuzzy decision analysis which provides a generalized fuzzy decision analysis.

description: In this work, shape control of flexible structures using enforced deformations as
control actions is considered. The proposed scheme can be applied for morphing of truss structures, such as a radio-telescope bases, aircraft smart wings, spray booms etc. A static problem for different external loadings is considered. In order to control the shape of the structure, suitably designed deformations of selected structural members are applied. Applied deformations on selected control elements can be realized by means of several technologies: thermal stresses, piezoelectric effects, shape memory actuators etc. The shape of the structure is changed according to the environmental conditions. For instance, in order to have an optimal control of geometry of the aircraft smart wing, it should be modified in dependence of weather phenomena, air turbulence, pressure, flow velocity and others. In this paper the discrete steps of shape changing of the structure, which is under external loading and control, are shown.

description: The ability to modulate light at high speeds is of paramount importance for telecommunications, information processing, and medical imaging technologies. This has stimulated intense efforts to master optoelectronic switching at visible and near-infrared frequencies, although coping with current computer speeds in integrated architectures still remains a major challenge. As a partial success, midinfrared light modulation has been recently achieved through gating patterned graphene. Here we show that atomically thin noble metal nanoislands can extend optical modulation to the visible and near-infrared spectral range. We find plasmons in thin metal nanodisks to produce similar absorption cross-sections as spherical particles of the same diameter. Using realistic levels of electrical doping, plasmons are shifted by about half their width, thus leading to a factor-of-two change in light absorption. These results, which we substantiate on microscopic quantum theory of the optical response, hold great potential for the development of electrical visible and near-infrared light modulation in integrable, nanoscale devices.

description: Type Ia supernovae (SNe Ia) are well-known for their use in the measurement of cosmological distances, but our continuing lack of concrete knowledge about their progenitor stars is both a matter of debate and a source of systematic error. In our attempts to answer this question, we presented unambiguous evidence that LMC SNR 0509-67.5, the remnant of an SN Ia that exploded in the Large Magellanic Cloud 400 +/- 50 years ago, did not have any point sources (stars) near the site of the original supernova explosion, from which we concluded that this particular supernova must have had a progenitor system consisting of two white dwarfs (Schaefer & Pagnotta 2012). There is, however, evidence of nebulosity near the center of the remnant, which could have been left over detritus from the less massive WD, or could have been a background galaxy unrelated to the supernova explosion. We obtained long-slit spectra of the central nebulous region using GMOS on Gemini South to determine which of these two possibilities is correct. The spectra show H-alpha emission at a redshift of z = 0.031, which implies that the nebulosity in the center of LMC SNR 0509-67.5 is a background galaxy, unrelated to the supernova.

description: Biopharmaceutical proteins have attracted increasing interest and been developed for treatment of various diseases due to their low toxicity, high affinity, and high efficacy. Subcutaneous injection, the most common delivery route for therapeutic proteins, requires high protein concentration formulations due to limited injection volume, resulting in challenges in manufacture, delivery, and stability of the drug products. Limited availability hinders the effective characterization of the physical properties of therapeutic proteins, especially during the early stage of development, where a large number of candidate formulations across a huge compositional space need to be screened. In this thesis, a droplet-based microfluidic device is innovated by incorporating a variety of sensing methods to quantify different physical properties of the concentrated protein solutions accurately and efficiently over a wide range of process-relevant parameters. Multiple particle tracking microrheology, birefringence, and turbidity are applied as the sensing methods to investigate viscosity, crystalline phase transitions, and phase separation of the protein solutions, respectively. The microfluidic technique provides data with high compositional resolution, and only requires a small sample volume. This work has demonstrated the potential of the developed novel technique to rapidly screen candidate formulations and provide guidance to facilitate the design of protein formulations to achieve desired properties. This technique can also be potentially applied as a complementary approach for computational methods to predict behaviors of high concentration formulations and facilitate understanding of the underlying mechanisms.

description: In this paper, we present a novel method for a base station (BS) to estimate the total downlink interference power received by any given mobile receiver, without information feedback from the user or information exchange between neighbouring BSs. The prediction method is deterministic and can be computed rapidly. This is achieved by first abstracting the cellular network into a mathematical model, and then inferring the interference power received at any location based on the power spectrum measurements taken at the observing BS. The analysis expands the methodology to a $\mathsf{K}$-tier heterogeneous network and demonstrates the accuracy of the technique for a variety of sampling densities. The paper demonstrates the methodology by applying it to an opportunistic transmission technique that avoids transmissions to channels which are overwhelmed by interference. The simulation results show that the proposed technique performs closely or better than existing interference avoidance techniques that require information exchange, and yields a 30% throughput improvement over baseline configurations.

description: The Chinese Small Telescope ARray (CSTAR) is a group of four identical, fully automated, static 14.5 cm telescopes. CSTAR is located at Dome A, Antarctica and covers 20 square degree of sky around the South Celestial Pole. The installation is designed to provide high-cadence photometry for the purpose of monitoring the quality of the astronomical observing conditions at Dome A and detecting transiting exoplanets. CSTAR has been operational since 2008, and has taken a rich and high-precision photometric data set of 10,690 stars. In the first observing season, we obtained 291,911 qualified science frames with 20-second integrations in the i-band. Photometric precision reaches about 4 mmag at 20-second cadence at i=7.5, and is about 20 mmag at i=12. Using robust detection methods, ten promising exoplanet candidates were found. Four of these were found to be giants using spectroscopic follow-up. All of these transit candidates are presented here along with the discussion of their detailed properties as well as the follow-up observations.

description: Dense packings of hard particles have important applications in many fields, including condensed matter physics, discrete geometry and cell biology. In this paper, we employ a stochastic search implementation of the Torquato-Jiao Adaptive-Shrinking-Cell optimization scheme [Nature 460, 876 (2009)] to find maximally dense particle packings in d-dimensional Euclidean space $\mathbb{R}^d$. While the original implementation was designed to study spheres and convex polyhedra in $d\ge3$, our implementation focuses on $d=2$ and extends the algorithm to include both concave polygons and certain convex or concave non-polygonal particle shapes. We verify the robustness of this packing protocol by successfully reproducing the known putative optimal packings of congruent copies of regular pentagons and octagons, then employ it to suggest dense packing arrangements of congruent copies of certain families of concave crosses, convex and concave curved triangles (incorporating shapes resembling the Mercedes-Benz logo), and "moon-like" shapes. Analytical constructions are determined subsequently to obtain the densest known packings of these particle shapes. For the examples considered, we find that the densest packings of both convex and concave particles with central symmetry are achieved by their corresponding optimal Bravais lattice packings; for particles lacking central symmetry, the densest packings obtained are non-lattice periodic packings, which are consistent with recently-proposed general organizing principles for hard particles. Moreover, we find that the densest known packings of certain curved triangles are periodic with a four-particle basis, and we find that the densest known periodic packings of certain moon-like shapes possess no inherent symmetries. Our work adds to the growing evidence that particle shape can be used as a tuning parameter to achieve a diversity of packing structures.

Identifying and Quantifying Recurrent Novae Masquerading as Classical Novae

description: Recurrent novae (RNe) are cataclysmic variables with two or more nova eruptions within a century. Classical novae (CNe) are similar systems with only one such eruption. Many of the so-called 'CNe' are actually RNe for which only one eruption has been discovered. Since RNe are candidate Type Ia supernova progenitors, it is important to know whether there are enough in our galaxy to provide the supernova rate, and therefore to know how many RNe are masquerading as CNe. To quantify this, we collected all available information on the light curves and spectra of a Galactic, time-limited sample of 237 CNe and the 10 known RNe, as well as exhaustive discovery efficiency records. We recognize RNe as having (a) outburst amplitude smaller than 14.5 - 4.5 * log(t_3), (b) orbital period >0.6 days, (c) infrared colors of J-H > 0.7 mag and H-K > 0.1 mag, (d) FWHM of H-alpha > 2000 km/s, (e) high excitation lines, such as Fe X or He II near peak, (f) eruption light curves with a plateau, and (g) white dwarf mass greater than 1.2 M_solar. Using these criteria, we identify V1721 Aql, DE Cir, CP Cru, KT Eri, V838 Her, V2672 Oph, V4160 Sgr, V4643 Sgr, V4739 Sgr, and V477 Sct as strong RN candidates. We evaluate the RN fraction amongst the known CNe using three methods to get 24% +/- 4%, 12% +/- 3%, and 35% +/- 3%. With roughly a quarter of the 394 known Galactic novae actually being RNe, there should be approximately a hundred such systems masquerading as CNe.

The Relativistic Inverse Stellar Structure Problem

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The observable macroscopic properties of relativistic stars (whose equations of state are known) can be predicted by solving the stellar structure equations that follow from Einstein's equation. For neutron stars, however, our knowledge of the equation of state is poor, so the direct stellar structure problem can not be solved without modeling the highest density part of the equation of state in some way. This talk will describe recent work on developing a model independent approach to determining the high-density neutron-star equation of state by solving an inverse stellar structure problem. This method uses the fact that Einstein's equation provides a deterministic relationship between the equation of state and the macroscopic observables of the stars which are composed of that material. This talk illustrates how this method will be able to determine the high-density part of the neutron-star equation of state with few percent accuracy when high quality measurements of the masses and radii of just two or three neutron stars become available. This talk will also show that this method can be used with measurements of other macroscopic observables, like the masses and tidal deformabilities, which can (in principle) be measured by gravitational wave observations of binary neutron-star mergers.

description: Lyman break galaxies (LBGs) at z ~ 3-4 are targeted to measure the fraction of Lyman continuum (LyC) flux that escapes from high redshift galaxies. However, z ~ 3-4 LBGs are identified using the Lyman break technique which preferentially selects galaxies with little or no LyC. We re-examine the standard LBG selection criteria by performing spectrophotometry on composite spectra constructed from 794 U_nGR-selected z ~ 3 LBGs from the literature while adding LyC flux of varying strengths. The modified composite spectra accurately predict the range of redshifts, properties, and LyC flux of LBGs in the literature that have spectroscopic LyC measurements while predicting the existence of a significant fraction of galaxies outside the standard selection region. These galaxies, termed Lyman continuum galaxies (LCGs), are expected to have high levels of LyC flux and are estimated to have a number density ~30-50 percent that of the LBG population. We define R_obs(U_n) as the relative fraction of observed LyC flux, integrated from 912A to the shortest restframe wavelength probed by the U_n filter, to the observed non-ionising flux (here measured at 1500A). We use the 794 spectra as a statistical sample for the full z ~ 3 LBG population, and find R_obs(U_n) = 5.0 +1.0/-0.4 (4.1 +0.5/-0.3) percent, which corresponds to an intrinsic LyC escape fraction of f_esc = 10.5 +2.0/-0.8 (8.6 +1.0/-0.6) percent (contamination corrected). From the composite spectral distributions we estimate R_obs(U_n) ~16 +/-3, f_esc ~33 +/-7 percent for LCGs and R_obs(U_n) ~8 +/-3, f_esc ~16 +/-4 percent for the combined LBG + LCG z ~ 3 sample. All values are measured in apertures defined by the UV continuum and do not include extended and/or offset LyC flux. A complete high redshift galaxy census and total emergent LyC flux is essential to quantify the contribution of galaxies to the epoch of reionisation.

En Tunisie, le bilan des accidents de la route laisse apparaître une situation critique en matière de sécurité routière, lorsqu’elle est comparée aux autres pays. La démarche proposée dans cet article est de s’attacher, en premier temps, à décrire le contexte tunisien et en souligner les spécificités géophysiques, démographiques, urbaines, socio-économiques. La contribution propose aussi un état des lieux de la mobilité et des accidents de la route et sa caractérisation. L’analyse de la situation permet de disposer d’une perspective générale dans laquelle s’inscrit le système de la sécurité routière en Tunisie. Dans un deuxième temps, une investigation empirique auprès des acteurs institutionnels de la sécurité routière aide à mettre en perspective les résultats de l’analyse descriptive et à établir un diagnostic approfondi des dysfonctionnements de la politique publique de sécurité routière en Tunisie. Il s’agit d’une approche qualitative compréhensive. L’analyse des enjeux, sur la base de consensus et de divergences institutionnels, conduit à établir des pistes d’actions possibles pour améliorer la situation. Celles-ci concernent à la fois le champ des réformes structurelles, organisationnelles, et managériales en faveur d’un meilleur ciblage des politiques publiques de sécurité routière.

description: In this paper, we consider a molecular diffusion based communications link that conveys information on the macro-scale (several metres). The motivation is to apply molecular-based communications to challenging electromagnetic environments. We first derive a novel capture probability expression of a finite sized receiver. The paper then introduces the concept of time-aggregated molecular noise at the receiver as a function of the rate at which the sensor can self-cleanse. The resulting inter-symbol-interference is expressed as a function of the sensor cleanse time, and the performance metrics of bit error rate, throughput and round-trip-time are derived. The results show that the performance is very sensitive to the sensor cleanse time and the drift velocity. The paper concludes with recommendations on the design of a real communication link based on these findings and applies the concepts to a test-bed.

 The “modules X studies” tab provides users access to fingerprint heatmap plots, for each of the aggregates and across the MSP and PROMISSE study groups. The position of the modules on the heatmap is not fixed. They are arranged instead according to similarities in abundance patterns via hierarchical clustering. In this case columns on the heatmap correspond to study groups, and rows correspond to individual modules. The proportion of transcripts for which abundance is significantly changed is shown again using gradated red and blue dots. Such maps can be accessed for each aggregate via the drop-down list directly above the plot (“Choose aggregate”). Notably, for figure preparation the zoom in/out function of the web browser can be used to increase the size of the image, thus improving its resolution. The image can then for instance be saved for used in reports or manuscript preparation.

description: The field distribution at the ports of the transmission line structure is computed by applying Maxwell's equations to the structure and solving an eigenvalue problem. The high dimensional sparse system matrix is complex in the presence of losses and Perfectly Matched Layer. A method is presented which preserves sparseness and delivers only the small number of interesting modes out with the smallest attenuation. The modes are found solving a sequence of eigenvalue problems of modified matrices with the aid of the invert mode of the Arnoldi iteration using shifts. A new strategy is described which allows the application of the method, first developed for microwave structures, to optoelectronic devices.

description: We use scanning tunneling microscopy to investigate the doping dependence of quasiparticle interference (QPI) in NaFe1-xCoxAs iron-based superconductors. The goal is to study the relation between nematic fluctuations and Cooper pairing. In the parent and underdoped compounds, where four-fold rotational symmetry is broken macroscopically, the QPI patterns reveal strong rotational anisotropy. At optimal doping, however, the QPI patterns are always four-fold symmetric. We argue this implies small nematic susceptibility and hence insignificant nematic fluctuation in optimally doped iron pnictides. Since Tc is the highest this suggests nematic fluctuation is not a prerequistite for strong Cooper pairing.

description: Truncus coeliacus’e (TC) kompressiooni sündroom on kroonilist kõhuvalu tekitav harv haigus, mille põhjustab keskse kaarsideme (KKS) surve TC-le ning mille sümptomid on seotud isheemia ja TC närvipõimiku neuropaatia kujunemisega. Vaevused varieeruvad, juhtivaks on rekurrentne kõhuvalu. TC kompressiooni diagnoosimiseks on vaja detailset Doppleri ultraheliuuringut (DUH-uuring) koos kompuutertomograafilise angiograafiaga (KTA), magnettomograafilise angiograafiaga (MRA) või konventsionaalse angiograafiaga (AG). TC olulise kompressiooni diagnoosimisel on otsustavaks DUH-uuringul ilmnev verevoolu kiiruste erinevus sisse- ja väljahingamisel. Ekspiiriumis TC stenoos süveneb ja DUH-uuringu järgi verevool kiireneb oluliselt. KTA, MRA või AG aitavad täpsustada TC anatoomiat ja kollateraalide olemasolu. TC kompressiooni sündroomi ravi valikmeetodiks on TC laparoskoopiline dekompressioon. Juhuleiuna avastatud TC kompressioon vaevusteta isikul ravi ei vaja. Artiklis on kirjanduse ülevaatele lisatud kokkuvõte kahest edukalt ravitud TC kompressiooni sündroomi haigusjuhust.

description: The Radical Pair Mechanism can help to explain avian orientation and navigation. Some evidence indicates that the intensity of external magnetic fields plays an important role in avian navigation. In this paper, based on a two-stage strategy, we demonstrate that birds could reasonably detect the directions of geomagnetic fields and gradients of these fields using a yield-based chemical compass that is sensitive enough for navigation. Also, we find that the lifetime of entanglement in this proposed compass is angle-dependent and long enough to allow adequate electron transfer between molecules.

description: Haiguse tõttu muutunud koe uuringu käsitluses leiab lisaks traditsioonilistele meetoditele üha enam rakendust digitaalne uurimine. Ligi kakskümmend aastat vanas valdkonnas tõi olulisima arengu kaasa tervikslaidi digiteerimise tehnoloogia, mille tulemusena saadud digitaalsed koelõigud on sobivaks andmestikuks masin- ja süvaõppel põhinevatele arendustele. Teema aktuaalsusele viitab viimastel aastatel hüppeliselt suurenenud virtuaalmikroskoopia ja digianalüüsi (nimetatakse kokku ka digipatoloogiaks) kasutamine diagnostilise meetodina, seda nii infotehnoloogilise arenduse, teaduslike rakenduste kui ka kliinilise kasutamise vallas. Digitaalne patohistoloogiline diagnostika leiab kliinilist rakendust rutiinsete ülesannete automatiseerimisel, näiteks kasvajamarkerite hindamisel. Tulevikuperspektiive nähakse uute prognostiliste markerite leidmises, koe virtuaalses värvimises, morfoloogilise ja molekulaarpatoloogilise info ühendamises ning kolmemõõtmelise kujutise loomises.

Atoopiline dermatiit – kas ainult sügelust põhjustav nahahaigus?
Creators: name: Gretško, Evelina
Publisher: name: Eesti Arst
Year: 2020

description: Atoopiline dermatiit on põletikuline sügelust põhjustav nahahaigus, mis on tingitud päriliku eelsoodumuse ja keskkonnategurite koosmõjust. Uuringud näitavad, et atoopilise dermatiidi levimus on viimastel aastakümnetel suurenenud ning selle haiguse all kannatab pea iga viies laps või nooruk. Paraku võib atoopilise dermatiidi diagnoosimine osutuda keeruliseks, kuna haiguse kliiniline pilt on mitmekesine ja mitte alati tüüpiline. Seetõttu on oluline tunda atoopilisele dermatiidile omaseid sümptomeid ning pakkuda elukvaliteeti tugevalt häirivale haigusele efektiivset ravi.
