description: Enhancement of global symmetry and supersymmetry in the infrared is one of the most intriguing phenomena in quantum field theory. We investigate such phenomena in a large class of three dimensional superconformal field theories, known as the S-fold SCFTs. Supersymmetric indices are computed for a number of theories containing small rank gauge groups. It is found that indices of several models exhibit enhancement of supersymmetry at the superconformal fixed point in the infrared. Dualities between S-fold theories that have different quiver descriptions are also analysed. We explore a new class of theories with a discrete global symmetry, whose gauge symmetry in the quiver has a different global structure from those that have been studied earlier.

Our data are too crude to reach conclusions regarding the evolutionary state of any particular cluster or to investigate whether the morphological evolution of galaxies matches the simple scenario we discuss, but the statistical nature of this study suggests that the observed evolutionary trends are universal in massive clusters.

description: We establish the existence of local, covariant time ordered products of local Wick polynomials for a free scalar field in curved spacetime. Our time ordered products satisfy all of the hypotheses of our previous uniqueness theorem, so our construction essentially completes the analysis of the existence, uniqueness and renormalizability of the perturbative expansion for nonlinear quantum field theories in curved spacetime. As a byproduct of our analysis, we derive a scaling expansion of the time ordered products about the total diagonal that expresses them as a sum of products of polynomials in the curvature times Lorentz invariant distributions, plus a remainder term of arbitrary low scaling degree.

description: Taust ja eesmärk. Eesti täiskasvanud rahvastiku tervisekäitumise uuring (TKU) on kõige pikemat aega korraldatud tervist käsitlev küsitlusuuring Eestis. Artiklis on kirjeldatud 2018. aasta kevadel toimunud 15. uuringuvooru metoodikat ja peamisi tulemusi. Meetodid. Läbilõikelise posti­ ja veebiküsitlusena toimunud uuring põhineb rahvastikuregistrist saadud kihitatud juhuvalimil (5000 kirjet), mis moodustati Eesti 16–64aastastest inimestest. Küsimustik hõlmas vastajate toitumist, kehalist aktiivsust ning liikluskäitumist, suitsetamist ja alkoholi tarvitamist, terviseseisundit ning arstiabi ja ravimite kasutust. Uuringu kohandatud vastamismäär oli 51,4%. Tulemused. Enamik toitumise, füüsilise vormi ja kehakaalu näitajaid ei ole võrreldes eelmise uuringuga oluliselt muutunud. Samuti ei ole alkoholi tarvitamise sageduses ja tarvitatud koguses võrreldes 2016. aasta tasemega olulist muutust toimunud. Statistiliselt oluliselt on vähenenud suitsetajate ning passiivse suitsetamise osakaal. Oma tervist hindas heaks või üsna heaks 50% vastanutest, teisalt on sama palju vastajaid, kellel esineb pikaajalisi terviseprobleeme või tervisega seotud igapäevategevuste piiranguid. Vähenenud on üleväsimust (43%) või depressiooni (17%) tundnud vastajate osakaal. Arstiabi ja ravimite kasutuses märgatavaid muutusi ei ole toimunud. Järeldused. TKU annab vajaliku tervikpildi Eesti tööealiste inimeste tervisest ja tervisekäitumisest. Uuringute ühetaoline metoodika ja ligi 30 aasta pikkune periood võimaldavad kirjeldada usaldusväärselt paljude näitajate muutust ajas.

First M87 Event Horizon Telescope Results. V. Physical Origin of the Asymmetric Ring

description: The Event Horizon Telescope (EHT) has mapped the central compact radio source of the elliptical galaxy M87 at 1.3 mm with unprecedented angular resolution. Here we consider the physical implications of the asymmetric ring seen in the 2017 EHT data. To this end, we construct a large library of models based on general relativistic magnetohydrodynamic (GRMHD) simulations and synthetic images produced by general relativistic ray tracing. We compare the observed visibilities with this library and confirm that the asymmetric ring is consistent with earlier predictions of strong gravitational lensing of synchrotron emission from a hot plasma orbiting near the black hole event horizon. The ring radius and ring asymmetry depend on black hole mass and spin, respectively, and both are therefore expected to be stable when observed in future EHT campaigns. Overall, the observed image is consistent with expectations for the shadow of a spinning Kerr black hole as predicted by general relativity. If the black hole spin and M87's large scale jet are aligned, then the black hole spin vector is pointed away from Earth. Models in our library of non-spinning black holes are inconsistent with the observations as they do not produce sufficiently powerful jets. At the same time, in those models that produce a sufficiently powerful jet, the latter is powered by extraction of black hole spin energy through mechanisms akin to the Blandford-Znajek process. We briefly consider alternatives to a black hole for the central compact object. Analysis of existing EHT polarization data and data taken simultaneously at other wavelengths will soon enable new tests of the GRMHD models, as will future EHT campaigns at 230 and 345 GHz.

description: Deep Chandra LETG+HRC-S observations of the isolated neutron star candidate RX J1856.5-3754 have been analysed to search for metallic and resonance cyclotron spectral features and for pulsation behaviour. As found from earlier observations, the X-ray spectrum is well-represented by a ~ 60 eV (7e5 K) blackbody. No unequivocal evidence of spectral line or edge features has been found, arguing against metal-dominated models. The data contain no evidence for pulsation and we place a 99% confidence upper limit of 2.7% on the unaccelerated pulse fraction over a wide frequency range from 1e-4 to 100 Hz. We argue that the derived interstellar medium neutral hydrogen column density of 8e19 <= N_H <= 1.1e20 per sq. cm favours the larger distance from two recent HST parallax analyses, placing RX J1856.5-3754 at ~ 140 pc instead of ~ 60 pc, and in the outskirts of the R CrA dark molecular cloud. That such a comparatively rare region of high ISM density is precisely where an isolated neutron star re-heated by accretion of interstellar matter would be expected is either entirely coincidental, or current theoretical arguments excluding this scenario for RX J1856.5-3754 are premature. Taken at face value, the combined observational evidence -- a lack of spectral and temporal features and an implied radius at infinity of 3.8-8.2 km that is too small for current neutron star models -- points to a more compact object, such as allowed for quark matter equations of state.

Sco X-1: Energy Transfer from the Core to the Radio Lobes

Publisher: name: arXiv
Year: 2001

subject: FOS: Physical sciences

description: The evolution of the radio emission from Sco X-1 is determined from a 56-hour continuous VLBI observation and from shorter observations over a four-year period. The radio source consists of a variable core near the binary, and two variable compact radio lobes which form near the core, move diametrically outward, then fade away. Subsequently, a new lobe-pair form near the core and the behavior repeats. The differences in the radio properties of the two lobes are consistent with the delay and Doppler-boosting associated with an average space velocity of 0.45c at 44 deg to the line of sight. Four lobe speeds, between 0.32c and 0.57c, were measured for several lobe-pairs on different days. The speed during each epoch remained constant over many hours. The direction of motion of the lobes over all epochs remained constant to a few degrees. Two core flares are contemporaneous with two lobe flares after removal of the delay associated with an energy burst moving with speed >0.95c in a twin-beam from the core to each lobe. This is the first direct measurement of the speed of energy flow within an astrophysical jet. The similarity of the core and lobe flares suggests that the twin-beam flow is symmetric and that the core is located near the base of the beam.

description: This work proposes a sustainable automated 3D scanning algorithm using drone photogrammetry for large scale archaeological sites. The proposed algorithm is energy-aware and sustainable since it uses an efficient path planning approach. It combines boustrophedon and spiral drone path planning algorithms. Moreover, concepts inspired by complex networks are also involved to model the environment as a network model with nodes and edges. The generated model is utilized in the proposed path planning algorithm. The findings show that the proposed algorithm is highly feasible and can efficiently scan large scale areas with minimum energy and time without human intervention.

description: We present a thermodynamic framework for the refined weak coupling limit. In this limit the interaction between system and environment is weak, but not negligible. As a result, the system dynamics becomes non-Markovian breaking divisibility conditions. Nevertheless, we propose a derivation of the first and second law just in terms of the reduced system dynamics. To this end, we extend the refined weak coupling limit for allowing slowly-varying external drivings, and reconsider the definition of internal energy due to the non-negligible interaction.

The role of agricultural co-operatives in Burma

Publisher: name: Canberra, ACT : The Australian National University
Year: 1985
Subjects: subject: Agriculture, Cooperative Burma
subject: Agriculture and state Burma
subject: Rural development Burma

description: Burma is a country with a long history of rural co-operatives and with new trends in the co-operative movement. The trend has recently been to move from lower to higher stages of cooperation - from credit provision to marketing, and from marketing to farming activities. The latest development is in the field of co-operative farming which involves joint efforts in cultivation of land leading to pooling of cultivation rights and to group farming. The major aim of this study is to see how agricultural co-operatives have contributed to rural development in Burma, to examine the causes of failure and success of the agricultural co-operative movement in the past, to review the present status of the movement, and to highlight ways and means that will encourage success in the future. The co-operative movement was started in Burma in 1905, under British rule, to free the small cultivator from dependence on private money-lenders. Much was expected of the movement, but it was a failure and this seriously damaged the image of co-operatives. After Burma regained its independence the Five Year Co-operative Plan was announced and agricultural co-operatives were formed to service its members with finance, to supply consumer goods and agricultural inputs, to sell produce and to promote thrift. Serious difficulties, including reliance on government loans, inefficiency compared to private traders and inadequate leadership, meant that most society did not serve their members well. When the Revolutionary Council came to power, bogus societies were liquidated and efforts were made to form new socialist co-operatives as a mode of socialist ownership of means of production. The co-operative was regarded as the only socially-acceptable form of socializing small-scale producers, but most of the peasants were unwilling to pool their land. The Ministry of Co-operatives adopted the Pilot Project for Co-operative Fanning which emphasised establishing co-operative farms on cultivable waste land. The Pilot Project aimed to attract farmers through demonstration of the benefits of co-operative farming. Most co-operative farms, however, appear to have failed to take full advantage of their large scale and have experienced management disadvantages. The majority of land remains under individual private ownership and management and the small-holders are still economically dominant. Co-operative farming is still in its infancy and has not taken firm root. Only state initiative and local leadership can give momentum to the movement. It has to rely on good management and new technology to achieve higher productivity and output in order to attract more farmers.

ANEMIA AMONG ANTENATAL MOTHERS IN abudwak district

description: Abstract

Anemia is a major public health concern, particularly among pregnant women in developing countries. This study investigates the factors contributing to anemia among antenatal mothers in Abudwak District, Somalia, assessing its prevalence, causes, and associated health risks. The research explores the impact of nutritional deficiencies, healthcare accessibility, socioeconomic conditions, and infections on maternal anemia.

Using a cross-sectional study design, data was collected through surveys, interviews, and laboratory tests conducted on pregnant women attending antenatal care. The findings indicate that iron deficiency, inadequate dietary intake, poor healthcare access, and high parasitic infection rates are the leading contributors to anemia in pregnancy. Cultural beliefs, food insecurity, and a lack of awareness about anemia prevention further exacerbate the problem.

The study emphasizes the urgent need for improved maternal nutrition programs, enhanced healthcare services, and strengthened public health policies to address anemia in pregnancy. Recommendations include increasing iron and folic acid supplementation, promoting community-based nutrition education, and improving antenatal care accessibility. These findings provide valuable insights for healthcare providers, policymakers, and organizations working to improve maternal and child health outcomes in Somalia.
Wave-particle Duality in Complex Quantum Systems

description: Stunning progresses in the experimental resolution and control of natural or man-made complex systems at the level of their quantum mechanical constituents raises the question, across diverse subdisciplines of physics, chemistry and biology, whether that fundamental quantum nature may condition the dynamical and functional system properties on mesoscopic if not macroscopic scales. But which are the distinctive signatures of quantum properties in complex systems, notably when modulated by environmental stochasticity and dynamical instabilities? It appears that, to settle this question across the above communities, a shared understanding is needed of the central feature of quantum mechanics: wave-particle duality. In this Perspective, we elaborate how randomness induced by this very quantum property can be discerned from the stochasticity ubiquitous in complex systems already on the classical level. We argue that in the study of increasingly complex systems such distinction requires the analysis of single incidents of quantum dynamical processes.

Short Timescale Correlations Between Line and Continuum Fluxes in Cygnus X-1
Creators: name: Maccarone, Thomas J.

Publisher: name: arXiv

description: We present the results of 16-s time scale spectral fits for Cygnus X-1 in the soft state and in the transition state, using a Comptonised blackbody plus an iron line. On these timescales, we find that that the continuum source flux can vary by factors 2-3 and that the iron line intensity appears to track these changes well, i.e., the inferred equivalent width of the line remains constant to within the errors. We also find no significant changes in the seed (blackbody) photon temperature, while the properties of the Comptonising corona clearly do vary, with the spectral hardness and flux generally being correlated. The corona therefore seems to be the overall driver for the rapid timescale variability observed in the soft and transition states. These results are consistent with the Fourier resolved spectroscopy results of Gilfanov et al. (2000) that indicate the iron line shows rapid flux variations while the blackbody component does not and suggest that the iron line flux in fact tracks continuum changes down to very short timescales. We extend this work by showing that not only the variability amplitudes, but also the {\it phases} of the iron line and continuum components are identical. We note that the short timescale variability properties of the soft and transition states are actually not very different from those of the hard state, suggesting that the corona is the main cause of rapid variability in that state too, and hence that the mechanism responsible for the corona is similar in all three states.

First M87 Event Horizon Telescope Results. VI. The Shadow and Mass of the Central Black Hole

description: We present measurements of the properties of the central radio source in M87 using Event Horizon Telescope data obtained during the 2017 campaign. We develop and fit geometric crescent models (asymmetric rings with interior brightness depressions) using two independent sampling algorithms that consider distinct representations of the visibility data. We show that the crescent family of models is statistically preferred over other comparably complex geometric models that we explore. We calibrate the geometric model parameters using general relativistic magnetohydrodynamic (GRMHD) models of the emission region and estimate physical properties of the source. We further fit images generated from GRMHD models directly to the data. We compare the derived emission region and black hole parameters from these analyses with those recovered from reconstructed images. There is a remarkable consistency among all methods and data sets. We find that >50% of the total flux at arcsecond scales comes from near the horizon, and that the emission is dramatically suppressed interior to this region by a factor >10, providing direct evidence of the predicted shadow of a black hole. Across all methods, we measure a crescent diameter of 42+/-3 micro-as and constrain its fractional width to be <0.5. Associating the crescent feature with the emission surrounding the black hole shadow, we infer an angular gravitational radius of GM/Dc2 = 3.8+/- 0.4 micro-as. Folding in a distance measurement of 16.8(+0.8,-0.7) Mpc gives a black hole mass of M = 6.5 +/- 0.2(stat) +/-0.7(sys) 10^9 Msun. This measurement from lensed emission near the event horizon is consistent with the presence of a central Kerr black hole, as predicted by the general theory of relativity.
The Fanaroff-Riley Transition and the Optical Luminosity of the Host Elliptical Galaxy

description: We show that a model for radio source dynamics we had earlier proposed can readily reproduce the relationship between the radio power division separating the two Fanaroff-Riley classes of extragalactic radio sources and the optical luminosity of the host galaxy, as found by Owen and Ledlow (1994). In our scenario, when less powerful jets eventually slow down to the point that the advance of the working surface (i.e., hotspot) becomes subsonic with respect to the external gas, the jet's collimation is severely weakened. This criterion distinguishes the powerful and well collimated FR II sources from the weaker sources producing the less collimated FR I type morphologies.

description: Compressed air is an important work medium for transfer of energy in many industrial processes. The inefficient physical processes used to produce it make compressed air one of the most expensive energy sources in supply systems. Even small leakages can over time result in high energy losses and costs if not detected and fixed timely. In addition, finding leakages in such systems is very time-consuming and expensive as the whole network of pipes must be examined to localize defects. This paper presents the concept of a targeted detection approach for effectively detecting and locating Compressed Air Leakages semi-autonomously through the usage of an Autonomous Mobile Robot as a mobile sensor. It describes how the detection process in an unknown environment can be rapidly accelerated by constraining the search space for the detection of leakages. The process utilizes expert knowledge, object detection and scene interpretation techniques to constrain the search space. The results obtained are integrated into an existing map of the environment and enable targeted repair actions. The evaluation includes an analysis of the individual phases of the approach, proposes further evaluation scenarios, and compares the efficiency of the approach with conventional manual leakage detection.
Vortex Unpinning in Precessing Neutron Stars

description: The neutron vortices thought to exist in the inner crust of a neutron star interact with nuclei and are expected to pin to the nuclear lattice. Evidence for long-period precession in pulsars, however, requires that pinning be negligible. We estimate the strength of vortex pinning and show that hydrodynamic forces present in a precessing star are likely sufficient to unpin all of the vortices of the inner crust. In the absence of precession, however, vortices could pin to the lattice with sufficient strength to explain the giant glitches observed in many radio pulsars.

description: Precise knowledge of a laser's wavelength is crucial for applications from spectroscopy to telecommunications. Here we present a wavemeter which operates on the Talbot effect. Tone parameter extraction algorithms are used to retrieve the frequency of the periodic signal obtained in the sampled Talbot interferogram. Theoretical performance analysis based on the Cramér-Rao lower bound (CRLB) as well as experimental results are presented and discussed. With this scheme, we experimentally demonstrate a compact and high-precision wavemeter with below 10 pm single-shot estimation uncertainty under the 3-$σ$ criterion around 780 nm.

description: The most general admissible boundary conditions are derived for an idealised Aharonov-Bohm flux intersecting the plane at the origin on the background of a homogeneous magnetic field. A standard technique based on self-adjoint extensions yields a four-parameter family of boundary conditions; other two parameters of the model are the Aharonov-Bohm flux and the homogeneous magnetic field. The generalised boundary conditions may be regarded as a combination of the Aharonov-Bohm effect with a point interaction. Spectral properties of the derived Hamiltonians are studied in detail.
