description: We have constructed a thermally compensated field-widened monolithic Michelson interferometer that can be used with a medium-resolution spectrograph to measure precise Doppler radial velocities of stars. Our prototype monolithic fixed-delay interferometer is constructed with off-the-shelf components and assembled using a hydrolysis bonding technique. We installed and tested this interferometer in the Exoplanet Tracker (ET) instrument at the Kitt Peak 2.1m telescope, an instrument built to demonstrate the principles of dispersed fixed delay interferometry. An iodine cell allows the interferometer drift to be accurately calibrated, relaxing the stability requirements on the interferometer itself. When using our monolithic interferometer, the ET instrument has no moving parts (except the iodine cell), greatly simplifying its operation. We demonstrate differential radial velocity precision of a few m s$^{-1}$ on well known radial velocity standards and planet bearing stars when using this interferometer. Such monolithic interferometers will make it possible to build relatively inexpensive instruments that are easy to operate and capable of precision radial velocity measurements. A larger multi-object version of the Exoplanet Tracker will be used to conduct a large scale survey for planetary systems as part of the Sloan Digital Sky Survey III (SDSS III). Variants of the techniques and principles discussed in this paper can be directly applied to build large monolithic interferometers for such applications, enabling the construction of instruments capable of efficiently observing many stars simultaneously at high velocity-precision.

description: This work aims to research an automatic method for detecting Age-related Macular Degeneration (AMD) lesions in RGB eye fundus images. For this, we align invasively obtained eye fundus contrast images (the "golden standard" diagnostic) to the RGB ones and use them to hand-annotate the lesions. This is done using our custom-made tool. Using the data, we train and test five different convolutional neural networks: a custom one to classify healthy and AMD-affected eye fundi, and four well-known networks: ResNet50, ResNet101, MobileNetV3, and UNet to segment (localize) the AMD lesions in the affected eye fundus images. We achieve 93.55% accuracy or 69.71% Dice index as the preliminary best results in segmentation with MobileNetV3.
Contested Development in Indonesia: Rethinking Ethnicity and Gender in Mining

description: This article reviews the literature on the relationship between gender and ethnicity in Indonesia’s mining sector and outlines shortcomings and prospects for further research. Recent studies on mining and gender focus predominantly on women and how they are negatively affected by mining. Ethnicity, although a growing asset in struggles on environmental transformations, is hardly included in research on mining. The intertwinement of ethnicity and gender in elaborations on mining is often depicted in literature of development programs and environmental organizations in which indigenous women are homogenized as marginalized victims. We argue, however, for a multidimensional approach on mining that takes into account the institutionalization of gender and ethnicity in mining governance as well as the role of gender and ethnic identities. Feminist political ecology and institutional analysis are pointing the way for such an approach. Furthermore, other relevant categories such as class, age, or status should be considered in the analysis of the complex and multidimensional environmental transformations of the mining sector in Indonesia.

description: Madrasostes simplex Paulian, 1989 Known distribution: East Malaysia (Sabah) (Paulian 1979) (Fig. 1B) Remarks. First record for West Malaysia (Selangor). Madrasostes simplex is extremely similar to M. variolosum and to M. reticulatum (Lansberge, 1887). Madrasostes variolosum is a very common species and has a wide distribution, ranging from Thailand to Borneo (based on first author’s unpublished data) and showing a clinal morphological variation in the sculpturing of elytra, while Madrasostes reticulatum is restricted to Sulawesi and the Philippines (although the Philippine population shows intermediate characters between M. variolosum and M. reticulatum). Madrasostes simplex can be easily distinguished from M. variolosum because of the sculpturing of elytra and pronotum and the shape of parameres.

description: Science Field Shops (SFSs) are an example of a transdisciplinary educational commitment where farmers, scientists, and extension staff exchange knowledge on agrometeorology in dialogue form to better respond to climate change. How can scientists, farmers, and extension staff build up this transdisciplinary collaboration? How has the agrometeorological learning environment been institutionalized in several places in Indonesia? An interdisciplinary collaboration between agrometeorology and anthropology serves as basis for developing seven climate services that are provided in the SFSs. Through Knowledge Transfer and Communication Technologies, farmers have become active learners, researchers, and decision makers of their own responses to the consequences of climate change. Although such an approach proves efficient in improving the farmers’ knowledge and anticipation capability, the transdisciplinary collaboration with state authority needs to be overhauled to improve the process.

description: We present results on the strong and electroweak NLO corrections to the production of a Higgs boson plus two hard jets via weak interactions at the LHC. The calculation includes all weak-boson fusion and quark-antiquark annihilation diagrams as well as all related interferences. We discuss corrections of different origin (QCD corrections of vector-boson-fusion type and interferences, electroweak corrections induced by quark or photonic initial states, heavy-Higgs-boson effects, etc.) and give some new results for distributions for a Higgs-boson mass of 200 GeV. The electroweak corrections are of the same size as the QCD corrections, viz. typically at the level of 5-10% for a Higgs-boson mass up to \sim 700 GeV. In general, they do not simply rescale differential distributions, but induce distortions at the level of 10%. The discussed corrections have been implemented in a flexible Monte Carlo event generator.

The Luminosity and Energy Dependence of Pulse Phase Lags in the Accretion-powered Millisecond Pulsar SAX J1808.4-3658

description: Soft phase lags, in which X-ray pulses in lower energy bands arrive later than pulses in higher energy bands, have been observed in nearly all accretion-powered millisecond pulsars, but their origin remains an open question. In a study of the 2.5 ms accretion-powered pulsar SAX J1808.4-3658, we report that the magnitude of these lags is strongly dependent on the accretion rate. During the brightest stage of the outbursts from this source, the lags increase in magnitude as the accretion rate drops; when the outbursts enter their dimmer flaring-tail stage, the relationship reverses. We evaluate this complex dependence in the context of two theoretical models for the lags, one relying on the scattering of photons by the accretion disk and the other invoking a two-component model for the photon emission. In both cases, the turnover suggests that we are observing the source transitioning into the "propeller" accretion regime.

description: We investigate the Josephson effect in the graphene nanoribbons of length $L$ smaller than the superconducting coherence length and an arbitrary width $W$. We find that in contrast to an ordinary superconducting quantum point contact (SQPC) the critical supercurrent $I_c$ is not quantized for the nanoribbons with smooth and armchair edges. For a low concentration of the carriers $I_c$ decreases monotonically with lowering $W/L$ and tends to a constant minimum for a narrow nanoribbon with $W\lesssim L$. The minimum $I_c$ is zero for the smooth edges but $eΔ_{0}/\hbar$ for the armchair edges. At higher concentrations of the carriers this monotonic variation acquires a series of peaks. Further analysis of the current-phase relation and the Josephson coupling strength $I_cR_N$ in terms of $W/L$ and the concentration of carriers revels significant differences with those of an ordinary SQPC. On the other hand for a zigzag nanoribbon we find that, similar to an ordinary SQPC, $I_c$ is quantized but to the half-integer values $(n+1/2)4eΔ_{0}/\hbar$.

Diversity of the proximal femur in humans: morphological variations of the head-neck junction
Creators: name: Radi, Nico <1984>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2014
Subjects: BIO/08 Antropologia

description: The proximal femur is a high-diversity region of the human skeleton, especially at the anterior junction between head and neck, where various bony morphologies have been recognized since mid nineteenth century. Classical literature on this topic is chaotic and contradictory, making almost impossible the comparison of data from different researches.	Starting from an extensive bibliographic review, the first standardized method to score these traits has been created. This method allows representing both the anatomical diversity of the region already described in literature and a part of variability not considered before, giving few and univocal definitions and allowing to collect comparable data. The method has been applied to three identified and five archaeological European skeletal collections, with the aim of investigating the distribution of these features by sex, age and side, in different places and time periods. It has also been applied to 3D digital reconstructions of femurs from CT scan files of coxo-femoral joints from fresh cadavers. In addition to the osseous traits described in the standardized method, the presence and frequency of some features known as herniation pits have been scored both on bones and on CT scans. The various osseous traits of the proximal femur are present at similar frequencies in skeletal samples from different countries and different historical periods, even if with clear local differentiation. Some of the features examined show significant trends related to their distribution by gender and age. Some hypotheses are proposed about the etiology of these morphologies and their possible implication with the acquisition of bipedalism in Humans. It is therefore highlighted the possible relation of some of these traits with the development of disorders of the hip joint. Moreover, it is not recommended the use of any of these features as a specific activity-related marker.

description: The following toolkit was developed from the results of an extensive educational research project that spanned over six years. The research project utilised auto-ethnography to recount and reflect upon professional learning over time, and when working with others. The overall account centred on a critical re-analysis of findings from four published journal articles, which I co-authored with others. The account offered a new insight into what the term blended learning might mean for team-teaching. The toolkit (as a result of the extensive research account) presented here draws attention to the educative potential of collaborating with others to develop scholarly understandings of practice, highlighting key elements of team-teaching when using blended learning. Reflective learning is a powerful way to investigate process and in this toolkit it is a key element for understanding blended learning for team-teaching in a new way.The utilisation of the PoP framework can encourage team-teaching members to continually massage a group-based inquiry mindset. This is especially so when establishing an agreed-to shared understanding to provide role clarity and instigate multiple communication strategies for good practice. Educational change agents are required to engage with deep understandings of practice through a process of reflective learning, collaboration, as well as the displaying of better ways to understand what effective team-teaching might mean. One can re-position team-teaching and blended learning as not just about the integration of technology into teaching and learning. Rather, blended learning is also about the importance of collaboratively unpacking teacher and student roles, responding to unique contexts/cultures of operation, and collectively instigating a purposefully designed team-teaching process to improve practice.The PoP toolkit (as a resource for users) can be used as a conversation starter or as a model to support others to design and implement an approach for effective team-teaching. The model has not been tested extensively. Therefore, I present the PoP toolkit as a work-in-progress that requires testing. The PoP was developed through a collaborative, reflective and observational process during several higher education research and practice initiatives over six years. This included the use of evidence gathered from several and diverse team-teaching situations in blended learning environments. I encourage users of the PoP toolkit to reach out to me and provide feedback. Practice should always be improved upon and never remain the same.

description: We report measurements of resistivity, magnetoresistivity, Hall effect, Seebeck coefficient, infrared reflectivity of undoped SmFeAsO and lightly doped SmFeAs(O0.93F0.07) oxypnictides. All the properties measured on SmFeAsO are characterized by clear signatures of the magnetic instability. A self-consistent picture emerges in which below the magnetic transition carrier condensation occurs due to the opening of spin density wave (SDW) gap. This is accompanied by the mobility increase of not gapped carriers due to the suppression of electron-electron scattering. SmFeAs(O0.93F0.07) exhibits an increase of the metallic character on cooling consistent with electron doping, even though at room temperature values of all the properties nearly overlaps with those of SmFeAsO. However, with temperature decrease all anomalies related to the SDW instability are missed and the superconducting transition occurs. This suggests that doping breaks abruptly the symmetries of the Fermi surface inhibiting the SDW formation in favor of the superconducting transition, with no substantial changes in the density of states or in the effective mass.

Weighted graphs defining facets: a connection between stable set and linear ordering polytopes

description: A graph is alpha-critical if its stability number increases whenever an edge is removed from its edge set. The class of alpha-critical graphs has several nice structural properties, most of them related to their defect which is the number of vertices minus two times the stability number. In particular, a remarkable result of Lovász (1978) is the finite basis theorem for alpha-critical graphs of a fixed defect. The class of alpha-critical graphs is also of interest for at least two topics of polyhedral studies. First, Chvátal (1975) shows that each alpha-critical graph induces a rank inequality which is facet-defining for its stable set polytope. Investigating a weighted generalization, Lipták and Lovász (2000, 2001) introduce critical facet-graphs (which again produce facet-defining inequalities for their stable set polytopes) and they establish a finite basis theorem. Second, Koppen (1995) describes a construction that delivers from any alpha-critical graph a facet-defining inequality for the linear ordering polytope. Doignon, Fiorini and Joret (2006) handle the weighted case and thus define facet-defining graphs. Here we investigate relationships between the two weighted generalizations of alpha-critical graphs. We show that facet-defining graphs (for the linear ordering polytope) are obtainable from 1-critical facet-graphs (linked with stable set polytopes). We then use this connection to derive various results on facet-defining graphs, the most prominent one being derived from Lipták and Lovász's finite basis theorem for critical facet-graphs. At the end of the paper we offer an alternative proof of Lovász's finite basis theorem for alpha-critical graphs.

description: We study the electronic states of the magnetically ordered Mn3Pt alloy within the density functional theory. Mn3Pt has been believed that one third of Mn atoms have no magnetic moment in an antiferromagnetic phase (so-called the F-phase) realized in the temperature range of 400 K < T < 475 K. We show that this experimentally suggested spin configuration is energetically so much unfavorable that it would be irrelevant to the F-phase. We discuss the possibility that the spin moments on the one third of Mn atoms are not paramagnetic but thermally fluctuating in the F-phase. The present results have an immediate connection with the recent neutron scattering study [T. Ikeda and Y. Tsunoda, J. Phys. Soc. Jpn., vol. 72, pp. 2614-2621, October. 2003.].

description: Network coding has the potential to improve the overall throughput of a network by combining different streams of data and forwarding them. In wireless networks, the wireless channel provide an excellent medium for physical layer network coding as signals from different transmitters are combined automatically by the wireless channel. In such scenarios, it would be interesting to investigate protocols and algorithms which can optimally relay information. In this paper, we look at a four-node two-way or bidirectional relay network, and propose a relay protocol which can relay information efficiently in this network.

description: In this paper, we consider a two-way or bidirectional communications system with a relay equipped with multiple antennas. We show that when the downlink channel state information is not known at the relay, the benefit of having additional antennas at the relay can only be obtained by using decode and forward (DF) but not amplify and forward (AF). The gain becomes significant when we employ transmit diversity together with wireless network coding. We also demonstrate how the performance of such system can be improved by performing antenna selection at the relay. Our results show that if downlink channel state information is known at the relay, network coding may not provide additional gain than simple antenna selection scheme.

description: We compare four open-loop transmit diversity schemes in a coded Orthogonal Frequency Division Multiplexing (OFDM) system with four transmit antennas, namely cyclic delay diversity (CDD), Space-Time Block Code (STBC, Alamouti code is used) with CDD, Quasi-Orthogonal STBC (QO-STBC) and Minimum-Decoding-Complexity QOSTBC (MDC-QOSTBC). We show that in a coded system with low code rate, a scheme with spatial transmit diversity of second order can achieve similar performance to that with spatial transmit diversity of fourth order due to the additional diversity provided by the phase shift diversity with channel coding. In addition, we also compare the decoding complexity and other features of the above four mentioned schemes, such as the requirement for the training signals, hybrid automatic retransmission request (HARQ), etc. The discussions in this paper can be readily applied to future wireless communication systems, such as mobile systems beyond 3G, IEEE 802.11 wireless LAN, or IEEE 802.16 WiMAX, that employ more than two transmit antennas and OFDM.

description: The use of microscopic discrete fluid volumes (i.e., droplets) as microreactors for digital microfluidic applications often requires mixing enhancement and control within droplets. In this work, we consider a translating spherical liquid droplet to which we impose a time periodic rigid-body rotation which we model using the superposition of a Hill vortex and an unsteady rigid body rotation. This perturbation in the form of a rotation not only creates a three-dimensional chaotic mixing region, which operates through the stretching and folding of material lines, but also offers the possibility of controlling both the size and the location of the mixing. Such a control is achieved by judiciously adjusting the three parameters that characterize the rotation, i.e., the rotation amplitude, frequency and orientation of the rotation. As the size of the mixing region is increased, complete mixing within the drop is obtained.

“Only if You Really, Really Need It”: Social Rights Consciousness in the Philippines
Creators: name: Reese, Niklas
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2017

description: This article argues that communitarianism, as the prevalent citizenship paradigm in the Philippines, observable also in modest expectations towards government services among Filipinos and a high emphasis on individual and community action, can be used to explain the lack of political change in the Philippines. In its first part, the article presents data on the sense of citizenship and concepts of social rights and obligations among Filipinos by combining findings from a series of problem-centered interviews with young urban professionals and quantitative data collected within annual surveys by the International Social Survey Programme (ISSP) on government, social inequality, and citizenship. The second part of the article attributes these findings to everyday concepts of citizenship as ideal-typical state responsibility theories and modern citizenship paradigms. By including ethnographic data, it discovers significant traits of communitarianism in Philippine everyday life. This section goes on to present how communitarianism (with its inherent character of exclusivity) impedes a democratic culture and moreover, how it is unable to serve as a guiding social philosophy in unifying a large-scale society mainly consisting of citizens who are strangers (ibang tao) to each other. Nevertheless, in conclusion, the article suggests the possibility of deepening and broadening the sense of citizenship in the Philippine society and its respect for the stranger by drawing on elements of Filipino culture.

A Continuous Vector-Perturbation for Multi-Antenna Multi-User Communication

description: The sum-rate of the broadcast channel in a multi-antenna multi-user communication system can be achieved by using precoding and adding a regular perturbation to the data vector. The perturbation can be removed by the modulus function, thus transparent to the receiver, but the information of the precoding matrix is needed to decode the symbols. This paper proposes a new technique to improve the multi-antenna multi-user system, by adding a continuous perturbation to the data vector without the need of information on the precoding matrix to be known at the receiver. The perturbation vector will be treated as interference at the receiver, thus it will be transparent to the receiver. The derivation of the continuous vector perturbation is provided by maximizing the signal-to-interference plus noise ratio or minimizing the minimum mean square error of the received signal.

description: Open-domain dialogue generation in natural language processing (NLP) is by default a pure-language task, which aims to satisfy human need for daily communication on open-ended topics by producing related and informative responses. In this paper, we point out that hidden images, named as visual impressions (VIs), can be explored from the text-only data to enhance dialogue understanding and help generate better responses. Besides, the semantic dependency between an dialogue post and its response is complicated, e.g., few word alignments and some topic transitions. Therefore, the visual impressions of them are not shared, and it is more reasonable to integrate the response visual impressions (RVIs) into the decoder, rather than the post visual impressions (PVIs). However, both the response and its RVIs are not given directly in the test process. To handle the above issues, we propose a framework to explicitly construct VIs based on pure-language dialogue datasets and utilize them for better dialogue understanding and generation. Specifically, we obtain a group of images (PVIs) for each post based on a pre-trained word-image mapping model. These PVIs are used in a co-attention encoder to get a post representation with both visual and textual information. Since the RVIs are not provided directly during testing, we design a cascade decoder that consists of two sub-decoders. The first sub-decoder predicts the content words in response, and applies the word-image mapping model to get those RVIs. Then, the second sub-decoder generates the response based on the post and RVIs. Experimental results on two open-domain dialogue datasets show that our proposed approach achieves superior performance over competitive baselines.

description: The Crab pulsar emits across a large part of the electromagnetic spectrum. Determining the time delay between the emission at different wavelengths will allow to better constrain the site and mechanism of the emission. We have simultaneously observed the Crab Pulsar in the optical with S-Cam, an instrument based on Superconducting Tunneling Junctions (STJs) with $μ$s time resolution and at 2 GHz using the Nançay radio telescope with an instrument doing coherent dedispersion and able to record giant pulses data. We have studied the delay between the radio and optical pulse using simultaneously obtained data therefore reducing possible uncertainties present in previous observations. We determined the arrival times of the (mean) optical and radio pulse and compared them using the tempo2 software package. We present the most accurate value for the optical-radio lag of 255 $\pm$ 21 $μ$s and suggest the likelihood of a spectral dependence to the excess optical emission asociated with giant radio pulses.

description: Einstein's general theory of relativity is the standard theory of gravity, especially where the needs of astronomy, astrophysics, cosmology and fundamental physics are concerned. As such, this theory is used for many practical purposes involving spacecraft navigation, geodesy and time transfer. Here I review the foundations of general relativity, discuss recent progress in the tests of relativistic gravity, and present motivations for the new generation of high-accuracy tests of new physics beyond general relativity. Space-based experiments in fundamental physics are capable today to uniquely address important questions related to the fundamental laws of nature. I discuss the advances in our understanding of fundamental physics that are anticipated in the near future and evaluate the discovery potential of a number of the recently proposed space-based gravitational experiments.

Community-Based Disaster Risk Management in the Philippines: Achievements and Challenges of the Purok System
Creators: name: Matthies, Angelina
Publisher: name: Austrian Journal of South-East Asian Studies

description: The purok system in the Philippines is promoted as a voluntary self-organization at the sub-village level which strengthens community resilience to natural hazards. In 2011, the system received the UN Sasakawa Award and gained prominence among the practitioner community. Based on a qualitative study in the municipality of San Francisco (Cebu province) from December 2014 to March 2015, the article elaborates on the achievements and challenges of the purok system. Striking merits encompass efficient and effective information dissemination and evacuation measurements between all levels of political administration that stem from the system’s remarkable enforcement of human and social capital. This is underpinned by a clear determination of roles and responsibility that is subsumed under the concept of accountability. However, the purok system faces internal challenges of maintenance and implies profound conceptual ambiguities regarding the notion of voluntarism and capabilities that favor clientelism. Nevertheless, the purok system clearly distinguishes itself from conventional community-based disaster risk management practices and implies potentials that are highly beneficial for strengthening resilience in disaster prone areas.

Uncertainty Relations for Shift-Invariant Analog Signals

description: The past several years have witnessed a surge of research investigating various aspects of sparse representations and compressed sensing. Most of this work has focused on the finite-dimensional setting in which the goal is to decompose a finite-length vector into a given finite dictionary. Underlying many of these results is the conceptual notion of an uncertainty principle: a signal cannot be sparsely represented in two different bases. Here, we extend these ideas and results to the analog, infinite-dimensional setting by considering signals that lie in a finitely-generated shift-invariant (SI) space. This class of signals is rich enough to include many interesting special cases such as multiband signals and splines. By adapting the notion of coherence defined for finite dictionaries to infinite SI representations, we develop an uncertainty principle similar in spirit to its finite counterpart. We demonstrate tightness of our bound by considering a bandlimited lowpass train that achieves the uncertainty principle. Building upon these results and similar work in the finite setting, we show how to find a sparse decomposition in an overcomplete dictionary by solving a convex optimization problem. The distinguishing feature of our approach is the fact that even though the problem is defined over an infinite domain with infinitely many variables and constraints, under certain conditions on the dictionary spectrum our algorithm can find the sparsest representation by solving a finite-dimensional problem.

Vector resolved energy fluxes and collisional energy losses in magnetic nozzle radiofrequency plasma thrusters

description: Energy losses in a magnetic nozzle radiofrequency plasma thruster are investigated to improve the thruster efficiency, which are calculated from particle energy losses in fully kinetic simulations. The simulations calculate particle energy fluxes with a vector resolution including the plasma energy lost to the dielectric wall, the plasma beam energy, and the divergent plasma energy in addition to collisional energy losses. As a result, distributions of energy losses in the thruster and the ratios of the energy losses to the input power are obtained. The simulation results show that the plasma energy lost to the dielectric is dramatically suppressed by increasing the magnetic field strength and the ion beam energy increases instead. In addition, the divergent ion energy and collisional energy losses account for approximately 4-12% and 30-40%, respectively, regardless of the magnetic field strength.
Study of the island morphology at the early stages of Fe/Mo(110) MBE growth

description: We present theoretical study of morphology of Fe islands grown at Mo(110) surface in sub-monolayer MBE mode. We utilize atomistic SOS model with bond counting, and interactions of Fe adatom up to third nearest neighbors. We performed KMC simulations for different values of adatom interactions and varying temperatures. We have found that, while for the low temperature islands are fat fractals, for the temperature 500K islands have faceted rhombic-like shape. For the higher temperature, islands acquire a rounded shape. In order to evaluated qualitatively morphological changes, we measured averaged aspect ration of islands. We calculated dependence of the average aspect ratio on the temperature, and on the strength of interactions of an adatom with neighbors.

description: We use the quasi-static particle-in-cell code QuickPIC to perform full-scale, one-to-one LWFA numerical experiments, with parameters that closely follow current experimental conditions. The propagation of state-of-the-art laser pulses in both preformed and uniform plasma channels is examined. We show that the presence of the channel is important whenever the laser self-modulations do not dominate the propagation. We examine the acceleration of an externally injected electron beam in the wake generated by 10 J laser pulses, showing that by using ten-centimeter-scale plasma channels it is possible to accelerate electrons to more than 4 GeV. A comparison between QuickPIC and 2D OSIRIS is provided. Good qualitative agreement between the two codes is found, but the 2D full PIC simulations fail to predict the correct laser and wakefield amplitudes.

A measurement of large-scale peculiar velocities of clusters of galaxies: technical details

description: This paper presents detailed analysis of large-scale peculiar motions derived from a sample of ~ 700 X-ray clusters and cosmic microwave background (CMB) data obtained with WMAP. We use the kinematic Sunyaev-Zeldovich (KSZ) effect combining it into a cumulative statistic which preserves the bulk motion component with the noise integrated down. Such statistic is the dipole of CMB temperature fluctuations evaluated over the pixels of the cluster catalog (Kashlinsky & Atrio-Barandela 2000). To remove the cosmological CMB fluctuations the maps are Wiener-filtered in each of the eight WMAP channels (Q, V, W) which have negligible foreground component. Our findings are as follows: The thermal SZ (TSZ) component of the clusters is described well by the Navarro-Frenk-White profile expected if the hot gas traces the dark matter in the cluster potential wells. Such gas has X-ray temperature decreasing rapidly towards the cluster outskirts, which we demonstrate results in the decrease of the TSZ component as the aperture is increased to encompass the cluster outskirts. We then detect a statistically significant dipole in the CMB pixels at cluster positions. Arising exclusively at the cluster pixels this dipole cannot originate from the foreground or instrument noise emissions and must be produced by the CMB photons which interacted with the hot intracluster gas via the SZ effect. The dipole remains as the monopole component, due to the TSZ effect, vanishes within the small statistical noise out to the maximal aperture where we still detect the TSZ component. We demonstrate with simulations that the mask and cross-talk effects are small for our catalog and contribute negligibly to the measurements. The measured dipole thus arises from the KSZ effect produced by the coherent large scale bulk flow motion.

Recombination Lines of Embedded Star Clusters

description: Aims. We are trying to probe conditions in the youngest super star clusters, those still embedded in dense obscuring clouds. Methods. The hydrogen recombination lines in the radio and infrared can be observed through the obscuration, as the optical and UV lines cannot, and give us the kinematics of the ionized gas. Results. The line profiles of the clusters resemble superpositions of the lines of many very young ultra-compact or hyper-compact HII regions. This can be explained if each OB star is individually embedded in dense material which it is accreting, even as it ionizes. Conclusions. We speculate on what this implies for the status and evolutionary state of cluster stars.
Islamic Philanthropy in Indonesia: Modernization, Islamization, and Social Justice
Creators: name: Fauzia, Amelia
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2017

description: This article discusses the potentials and constraints of social justice philanthropy in Indonesia in the context of two trends – of growing Islamization and modernization. It employs interviews and recent observations together with survey data. Although the challenges facing social justice philanthropy remain immense, the pathways to development have been created; pathways through which the gap that exists between faith-based philanthropy and its secular counterparts may become smaller. Looking at growing philanthropization in the last 15 years and the pre-existing popularity of the concept of social justice among the population, could social justice and developmentalism may become the future of Islamic philanthropy in the country? The author argues that modernization and Islamization encourage the practice of philanthropy, but that they do not necessarily contribute to the development of a philanthropy that focuses on social justice. The modernization of the philanthropy sector has shown scattered pictures of development into a form of social justice philanthropy, which remains small but nevertheless encouraging.
