description: The intense theoretical and experimental interest in topological insulators and semimetals has established band structure topology as a fundamental material property. Consequently, identifying band topologies has become an important, but often challenging problem, with no exhaustive solution at the present time. In this work we compile a series of techniques, some previously known, that allow for a solution to this problem for a large set of the possible band topologies. The method is based on tracking hybrid Wannier charge centers computed for relevant Bloch states, and it works at all levels of materials modeling: continuous k.p models, tight-binding models and ab initio calculations. We apply the method to compute and identify Chern, Z2 and crystalline topological insulators, as well as topological semimetal phases, using real material examples. Moreover, we provide a numerical implementation of this technique (the Z2Pack software package) that is ideally suited for high-throughput screening of materials databases for compounds with non-trivial topologies. We expect that our work will allow researchers to: (a) identify topological materials optimal for experimental probes, (b) classify existing compounds and (c) reveal materials that host novel, not yet described, topological states.

description: Introduction: Youth who begin early sexual activity are less likely to use condoms and more likely to have multiple partners and early child bearing which intern brings about higher rates of maternal and child morbidity and mortality. Higher rates of unintended pregnancy, HIV/AIDS and other sexually transmitted infections among youths make it fundamental to understand factors associated with early sexual initiation in a wider perspective for designing and implementing effective interventions. Objective: To assess the magnitude of early sexual initiation and its associated factors among youths in Addis Ababa, April 2014 Methodology: A quantitative cross sectional facility based study supplemented with qualitative enquiry was conducted on a sample of 622 youth's attending youth centers in Addis Ababa. A systematic random sampling technique was applied to select the study participants. A pretested structured questionnaire was used to collect quantitative data while focus group discussions using semi-structured interviewer guide were used to generate qualitative information. Bivariate and multivariate analyses were done. Odds ratio with 95% confidence interval was estimated to identify predictors of early sexual debut using multivariable logistic regression analysis. Qualitative data were analyzed using thematic analysis. Result: Early sexual initiation (sex before the age of 18yrs) among youth in Addis Ababa was 42%. Among youths who had history of sexual debut at early age thirty-seven percent of them didn't use condom at first sex and 44% of male participant had sex with commercial sex workers in their life time. Multivariate analysis:-Being female AOR = 4.46(1.41, 14.15), younger age group AOR= 3.20[1.50, 6.82], school attendance AOR=3.52(2.14, 5.79), reported pressure to have sexual intercourse AOR=2.18(1.13, 4.23), watching sex movies at early age AOR=7.27(3.65, 14.48) and using alcohol AOR=2.48(1.09, 5.63) were identified as independent predictors of early sexual initiation. Regarding consequences 37% of pregnancies were before the age of 18years. In addition, 47% of youths had history of STI in the past 12 month prior to survey. Conclusions: This study indicates that a considerable proportion of youths engages in sexual activity at an early age and continues to practice risky sexual behaviors. Peer influence played a major role in youths sexual behaviors. Watching sex movies at younger age (15-19) and use of alcohol were found to be independent predictor of early sexual initiation. In order to protect youth from early sexual debut, schools should focus on promoting peer educators and the way of peer discussion. Strategies should be designed to control the use of alcohol and to restrict watching sex movies at early age

description: This paper introduces a new neural-network-based approach, namely In-Context Operator Networks (ICON), to simultaneously learn operators from the prompted data and apply it to new questions during the inference stage, without any weight update. Existing methods are limited to using a neural network to approximate a specific equation solution or a specific operator, requiring retraining when switching to a new problem with different equations. By training a single neural network as an operator learner, we can not only get rid of retraining (even fine-tuning) the neural network for new problems, but also leverage the commonalities shared across operators so that only a few demos in the prompt are needed when learning a new operator. Our numerical results show the neural network's capability as a few-shot operator learner for a diversified type of differential equation problems, including forward and inverse problems of ordinary differential equations (ODEs), partial differential equations (PDEs), and mean-field control (MFC) problems, and also show that it can generalize its learning capability to operators beyond the training distribution.

description: We study a testable dark matter (DM) model outside of the standard WIMP paradigm in which the observed ratio $Ω_{\rm dark} \simeq Ω_{\rm visible}$ for visible and dark matter densities finds its natural explanation as a result of their common QCD origin when both types of matter (DM and visible) are formed at the QCD phase transition and both are proportional to $Λ_{\rm QCD}$. Instead of conventional "baryogenesis" mechanism we advocate a paradigm when the "baryogenesis" is actually a charge separation process which always occur in the presence of the $\cal{CP}$ odd axion field $a(x)$. In this scenario the global baryon number of the Universe remains zero, while the unobserved anti-baryon charge is hidden in form of heavy nuggets, similar to Witten's strangelets and compromise the DM of the Universe. We argue that the nuggets will be inevitably produced during the QCD phase transition as a result of Kibble-Zurek mechanism on formation of the topological defects during a phase transition. Relevant topological defects in our scenario are the closed bubbles made of the $N_{\rm DW}=1$ axion domain walls. These bubbles, in general, accrete the baryon (or anti baryon) charge, which eventually result in formation of the nuggets and anti-nuggets carrying a huge baryon (anti-baryon) charge. The main consequence of the model, $Ω_{\rm dark} \approx Ω_{\rm visible}$ is insensitive to the axion mass which may assume any value within the observationally allowed window $10^{-6} {\rm eV} \lesssim m_a \lesssim 10^{-3}{\rm eV}$. We also estimate the baryon to entropy ratio $η\equiv {n_B}/{n_γ}\sim 10^{-10}$ within this scenario. Finally, we comment on implications of these results to the axion search experiments, including microwave cavity and the Orpheus experiments.

description: Making Inter- and Intranet resources available in a structured way is one of the most important and challenging problems today. An underlying structure allows users to search for information, documents or relationships without a clearly defined information need. While search and filtering technology is becoming more and more powerful, the development of such explorative access methods lacks behind. This work is concerned with the development of large-scale data mining methods that allow to structure information spaces based on loosely coupled user annotations and navigation patterns. An essential challenge, that was not yet fully realized in this context, is heterogeneity. Different users and user groups often have different preferences and needs on how to access an information collection. While current Business Intelligence, Information Retrieval or Content Management solutions allow for a certain degree of personalization, these approaches are still very static. This considerably limits their applicability in heterogeneous environments. This work is based on a novel paradigm, called collaborative structuring. This term is chosen as a generalization to the term collaborative filtering. Instead of only filtering items, collaborative structuring allows users to organize information spaces in a loosely coupled way, based on patterns emerging through data mining. A first contribution of the work is to define the conceptual notion of collaborative structuring as combinatorial optimization problem and to put it into relation with existing research in the areas of data and web mining. As second contribution, highly scalable, distributed optimization strategies are proposed and analyzed. Finally, the proposed approaches are quantitatively evaluated against existing methods using several real-world data sets. Also, practical experience from two application areas is given, namely information access for heterogeneous expert communities and collaborative media organization.

description: Background: Injuries in small scale enterprises are becoming a public health problem in developing countries including Ethiopia. The prevailing injuries could be prevented if appropriate measures are taken. In developing countries including Ethiopia, the risk of having work related injury is 10 to 20 times higher than that of developed countries. Objective: This study investigated the magnitude and associated factors of occupational injuries among microenterprise metal workshop workers in Addis Ababa. Methods: work-site based cross sectional study was employed among 540 micro metal workshop workers in Addis Ababa. Thirty (30%) of the Sub cities with the highest number of labor force were selected and sample size was allocated for each sub city based on proportional probability sampling. Firms were selected by simple random sampling. Trained data collectors administered a standardized questionnaire through face- to-face interview to collect information regarding participants practice, work-related and socio-demographic factors and outcome variable. Observational checklist was used to ascertain the information with quantitative findings. Data were checked for its completeness and coded and entered into Epi Info version 7.2.1.0. Data were analyzed using SPSS version 22 where descriptive and logistics regressions were computed to see association between different factors and work related injuries. Results: The overall annual prevalence rate of work related injury was 53.5% (95% CI: 49.4%, 57.7%). The significant contributing factors for work related injuries in metal workshops were work experience with five year or less (AOR: 4.85, 95% CI: 2.68, 8.79), working without shift (AOR: 8.93, 95% CI: 3.81, 20.97), work dissatisfaction (AOR: 3.25, 95% CI: 1.86, 5.66), alcohol drinking (AOR: 7.05, 95% CI: 4.07, 12.22) and not using PPEs (AOR: 2.94, 95% CI: 1.46, 5.91). Conclusion: Occupational injuries were found to be high. Lack of work experience, educational status, taking excessive alcohol, lack of work shift, health and safety training and supervision and not using PPEs increased the risk of work related injuries.

description: The flow of electric current through a two-dimensional material in a magnetic field gives rise to the family of Hall effects. The quantum versions of these effects accommodate robust electronic edge channels and fractional charges. Recently, the Hall effect of skyrmions, classical magnetic quasiparticles with a quantized topological charge, has been theoretically and experimentally reported, igniting ideas on a quantum version of this effect. To this end, we perform dynamical mean field theory calculations on localized $f$ electrons coupled to itinerant $c$ electrons in the presence of spin-orbit interaction and a magnetic field. Our calculations reveal localized nano quantum skyrmions that start moving transversally when a charge current in the itinerant electrons is applied. The results show the time-transient build-up of the quantum skyrmion Hall effect, accompanied by an Edelstein effect and a magnetoelectric effect that rotate the spins. This work motivates studies about the steady state of the quantum skyrmion Hall effect, looking for eventual quantum skyrmion edge channels and their transport properties.

Thanks to: (i) a careful finite-size scaling analysis of the critical exponents, (ii) the accurate estimate of the first three moments of the height fluctuations, we can quantify the wandering exponent with unprecedented precision: $χ_{d=2} = 0.3869(4)$. This figure is incompatible with the long-standing conjecture due to Kim and Koesterlitz that hypothesized $χ_{d=2}=2/5$.

description: Recent years have witnessed tremendous progresses in creating and manipulating ground-state ultracold polar molecules. However, the two-body loss regardless of the chemical reactivities is still a hurdle for many future explorations. Here, we investigate the loss suppression of non-reactive bosonic $^{23}$Na$^{87}$Rb molecules with a circular polarized microwave blue-detuned to the rotational transition. We achieve suppression of the loss by two orders of magnitude with the lowest two-body loss rate coefficient reduced to $3\times10^{-12}~\rm{cm^3/s}$. Meanwhile, the elastic collision rate coefficient is increased to the $10^{-8}~\rm{cm^3/s}$ level. The large good-to-bad collision ratio has allowed us to carry out evaporative cooling of $^{23}$Na$^{87}$Rb with an efficiency of 1.7(2), increasing the phase-space density by a factor of 10. With further improvements, this technique holds great promises for creating a Bose-Einstein condensate of ultracold polar molecules.

description: A total synthesis of the pterocarpene derivative erypoegin H has been devised. This isoflavonoid has been recently isolated from Erythrina poeppigiana and possesses bactericidal activity against a range of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci. The application of a PtCl2-catalyzed carboalkoxylation of alkynes as the key step afforded not only a quick access to erypoegin H in high yields, but also led to the synthesis of its cognates sojagol and phaseol. Furthermore, a novel user-friendly in situ generated catalyst for alkyne metathesis has been developed. Mixing trichloro molybdenum nitride (NMoCl3) and lithium triphenylsilanolate (Ph3SiOLi) forms a species which performs cross alkyne metathesis (CAM) as well as ring-closing alkyne metathesis (RCAM). The tolerance of a broad range of functional groups including esters, ethers, amides, carbamates, thiophenes, thioethers and sulfones was shown. The employment of propargylic ethers was also demonstrated for the first time in an alkyne metathesis. This new substrate class was used in a CAM as a key step for a concise total synthesis of gallicynoic acid I.

Year: 2002

description: The practice of female genital mutilation (FGM), in one form or another continues to exist in around 40 countries of the world. It is associated with different kinds of health problems which manifest immediately or long after the wound has healed. Health hazards during delivery are among the long term complications of FGM. With the objectives of assessing and comparing the differential occurrence of birth complications among the different types of female genital mutilation, a cross-sectional study using questionnaire was conducted on December 2001 in Jijiga town among 913 women of reproductive age who had their first birth during the last five years. The proportion of women who were genitally mutilated was 96% with 52% of them undergone the most severe type of FGM – infibulation. The rest 48% of women had undergone either FGM Type I or Type II; i.e., they were genitally mutilated but not infibulated. Episiotomies occurred among 61% of women who were delivering for the first time and 28.1% of women delivering for the second time. The rates of instrumental and cesarean deliveries among the first-time deliveries were 6.6% and 3.1%, respectively; while they were 3.2% and 1.3% among the second-time deliveries, respectively. Among primi-parous women 36.2% reported having had complicated postnatal period; 22.5%, prolonged labour; 10.3%, perineal tear and 9.8%, heavy bleeding. Internal comparison between infibulated and non-infibulated women had shown that there was a significant difference in the occurrence of hemorrhage and postnatal problems. It was concluded that female genital mutilation in general and infibulation in particular were risk factors for the occurrence of birth complications. Collaborative educational interventions were recommended

description: The most important difference between ultrastrong and non-ultrastrong coupling regimes is that the ground state contains excitations. We consider a qubit-plasmon-phonon ultrastrong coupling (USC) system with a three-level atom coupled to the photon and phonon via its upper two energy levels and show that spontaneous emission of the atom from its intermediate to its ground state produces photon and phonon pairs. It is shown that the current system can produce a strong photon/phonon stream and the atom-phonon coupling plays the active role, which ensures the experimental detection. The emission spectrum and various high-order correlation functions confirm the generation of the pairs of photons and phonons. Our study has important implications for future research on virtual photon and phonon pairs creation in the ground state of the USC regime.

description: We propose a new method to probe the Warm Hot Intergalactic Medium (WHIM) beyond the virial radius (R_200) of a cluster of galaxies, where X-ray observations are not easily achievable. In this method, we use dispersion measures (DMs) of Fast Radio Bursts (FRBs) that appear behind the cluster and the Sunyaev-Zel'dovich (SZ) effect towards the cluster. The DMs reflect the density of the intracluster medium (ICM) including the WHIM. If we observe a sufficient number of FRBs in the direction of the cluster, we can derive the density profile from the DMs. Similarly, we can derive the pressure profile from the SZ effect. By combining the density and the pressure profiles, the temperature profile can be obtained. Based on mock observations of nearby clusters, we find that the density of the WHIM can be determined even at > 2 R_200 from the cluster center when FRB observations with the Square Kilometre Array (SKA) become available. The temperature can be derived out to r~ 1.5 R_200, and the radius is limited by the current sensitivity of SZ observations.

description: Background: Skilled health personnel attended delivery is a key for reduction of maternal mortality ratio and also for better perinatal outcome of the fetus/neonate. Our endless concern about place of childbirth care is not for nothing Therefore, choices of places of childbirth care and its related factors are important for maternal health care outcomes. Objective: The objective of the study is to assess the patterns and factors of choice of place of childbirth care service in Kirkos Sub City, Addis Ababa Ethiopia. Method: A community based survey with face to face interview using a structured and pretested questionnaire was conducted from April 1 to July 30, 2018 on a sample of 594 women who had experienced child birth within the last 12 months prior to the study. Simple random sampling to select woredas and systematic random sampling was used to contact eligible woman. Women with a child less than one years of age in each woreda are interviewed until the sample size in each woreda is completed. Data were entered and analyzed using EPI info v.7 and SPSS version 20. Univariable analysis was done to describe some important characteristics of study subjects. Multivariable analysis using binary logistic regression technique was done to see the association between the independent variables and the dependent variable. In multivariable analyses odds ratio with 95% confidence interval was estimated to identify predictors of patterns of place of childbirth care service by controlling the effect of others. Result: In this study, of the 594 women who had given birth in last 12 month prior to the study period selected as sample, only 544 women responded to the questionnaire; make the response rate 92%. Majority of respondents have given birth and also have plan to give birth in future in public childbirth care facilities. 434 (79.7%), 105 (19.3%) and 5(1.00%) of respondents had delivered in public, private health childbirth care facilities and at home respectively. Level of education, place of antenatal care woman attended and pervious obstetric complication showed stastically significant with women's choices for places of childbirth care service. Conclusion: Most of women gave birth in public childbirth care facility. In general, the present study showed that women have a confidence on public childbirth care service despite there is a commonly perceived doubt in quality in public child birth care. Recommendation: Therefore, health programmer and service providers at all level should work to ensure pubic childbirth care centers fulfill the minimum standard of childbirth care services to help women with labour.

description: Treating the horizon radius as an order parameter in a thermal fluctuation, the free energy landscape model sheds light on the dynamic behaviour of black hole phase transitions. Here we carry out the first investigation of the dynamics of the recently discovered multicriticality in black holes. We specifically consider black hole quadruple points in D=4 Einstein gravity coupled to non-linear electrodynamics. We observe thermodynamic phase transitions between the four stable phases at a quadruple point as well as the weak and strong oscillatory phenomena by numerically solving the Smoluchowski equation describing the evolution of the probability distribution function. We analyze the dynamic evolution of the different phases at various ensemble temperatures and find that the probability distribution of a final stationary state is closely tied to the structure of its off-shell Gibbs free energy.

description: Questo saggio presenta le riflessioni di un docente e di uno studente sulla preparazione, l'approccio didattico e il valore delle Olimpiadi Internazionali di Filosofia (IPO) come evento culturale ed esperienza personale. Attraverso il duplice punto di vista - dell'insegnante e del discente - si evidenzia con acutezza come l'esperienza delle IPO sia un'occasione di crescita per gli studenti, proprio per il loro riferirsi a conoscenze non immediatamente economizzabili e spendibili nel mondo del lavoro; e d'altra parte, la preparazione necessaria per imparare a comporre in modo appropriato il saggio per la competizione, obbliga i docenti italiani a operare una sintesi nell'insegnamento della filosofia tra l'approccio "storico-narrativo" e quello "tematico".

This essay presents the reflections of a teacher and a student on the preparation, teaching approach and the value of the International Philosophy Olympiad (IPO) as a cultural event and personal experience. Through the dual point of view – of the teacher and the learner – it is sharply pointed out how the experience of the IPO is an occasion of growth for students, precisely because of their referring to knowledge that is not immediately economize-able and expendable in the world of work; and on the other hand, the preparation required to learn how to appropriately compose the essay for the competition, obliges Italian teachers to make a synthesis in the teaching of philosophy between the ‘historical-narrative’ and ‘thematic’ approaches.

description: Einseitig hörbeeinträchtigte Kinder bewerten ihr Befinden gemäss dem HfH-Forschungsprojekt „Befindensqualität hörbehinderter Kinder in Schule und Freizeit“ (Audeoud & Wertli, 2009) tendenziell am tiefsten. Deshalb befasst sich die vorliegende Studie mit den spezifischen audiologischen Schwierigkeiten und deren möglichen Folgen auf das aktuelle subjektive Befinden von einseitig hörbeeinträchtigten Kindern. Durch eingehendere Untersuchung der vorhandenen Daten wird quantitativ erforscht, wie das aktuelle subjektive Befinden einseitig hörbeeinträchtigter Schulkinder durch unterschiedliche Settings und die Faktoren Lautstärke und Hörgeräteversorgung beeinflusst wird. Die gewonnenen Erkenntnisse sind für die audiopädagogische Praxis relevant.

description: The Heisenberg-Kitaev model is a paradigmatic model to describe the magnetism in honeycomb-lattice Mott insulators with strong spin-orbit coupling, such as A$_2$IrO$_3$ (A = Na, Li) and $α$-RuCl$_3$. Here we study in detail the physics of the Heisenberg-Kitaev model in an external magnetic field. Using a combination of Monte-Carlo simulations and spin-wave theory we map out the classical phase diagram for different directions of the magnetic field. Broken SU(2) spin symmetry renders the magnetization process rather complex, with sequences of phases and metamagnetic transitions. In particular, we find various large-unit-cell and multi-Q phases including a vortex-crystal phase for a field in the [111] direction. We also discuss quantum corrections in the high-field phase.

description: Background: Health care expenditure is increasing worldwide. Determining the unit cost of medical services is one part of economic analysis which helps to improve efficient use of scarce resource. It is also a vital indicator needed by managers and policy makers. Most of the health institutions in our country have not yet properly established clear methods to calculate unit cost and set the service price. Objective: This study is conducted to explore the unit cost of health services provision and assess the payback at Tikur Anbessa Specialized Teaching Hospital(TASTH), Addis Ababa Ethiopia. The study has been conducted for the period of July 2017 to June 2018. Methods: Afacility based cross-sectional unit cost analysis has been conducted in order to identify the unit cost and compare it with the price. The top-down costing method wasapplied to calculate and allocate the overhead and intermediate cost centers to the final cost centers of TASTH for the year 2017/18GC (2010 EFY) froma provider perspective. Micro-costing method was applied to calculate unit cost of each service inthe final cost centers and, thecost was compared with the current hospital service charge. The average and range of different serviceunitscost, priceand Cost to recovery ratio (CRR)was calculated for further analysis. The study covered 273(22%)selected services out of the total 1,212services in the hospital. The costs data were calculated using Microsoft Excel 2010. Results:The average unit cost of different diagnostic services is 276.03ETB (range24.55-800.4), whereas the average unit price is 108 ETB with (MIN-MAX) that is (4-800). The average unit cost for different inpatient services is 813 ETB (range 51.4-3676.6) and the average unit price is 104ETB with a (MIN-MAX) that is(10-350). The average unit cost for outpatient services is 124.99, but the average price is 11.13 with (MIN-MAX) that is (5,30). From the total services analyzed 57(21%) of them have a no price sated, 157(58%) of them have CRRbetween(1% to25%), 27(10%) of them have CRR between 26% to 50% and 14(5%) of themhave CRR between(51% to 100%). Conclusion:The current study implies that costs of service provisions are considerably higher as compared to the corresponding services especially for Outpatient and inpatient services the CRR is only 9% and 13% respectively. The hospital administrative bodies and other concerned bodies should take measures in order to reduce the gaps between cost anduser fees so as to maintain financial sustainability of the hospital without compromising access to services for the poorest segment of the population.

description: User's home locations are used by numerous social media applications, such as social media analysis. However, since the user's home location is not generally open to the public, many researchers have been attempting to develop a more accurate home location estimation. A social network that expresses relationships between users is used to estimate the users' home locations. The network-based home location estimation method with iteration, which propagates the estimated locations, is used to estimate more users' home locations. In this study, we analyze the function of network-based home location estimation with iteration while using the social network based on following relationships on Twitter. The results indicate that the function that selects the most frequent location among the friends' location has the best accuracy. Our analysis also shows that the 88% of users, who are in the social network based on following relationships, has at least one correct home location within one-hop (friends and friends of friends). According to this characteristic of the social network, we indicate that twice is sufficient for iteration.

Ground State Properties of Quantum Skyrmions described by Neural Network Quantum States

description: We investigate the ground state properties of quantum skyrmions in a ferromagnet using variational Monte Carlo with the neural network quantum state as variational ansatz. We study the ground states of a two-dimensional quantum Heisenberg model in the presence of the Dzyaloshinskii-Moriya interaction (DMI). We show that the ground state accommodates a quantum skyrmion for a large range of parameters, especially at large DMI. The spins in these quantum skyrmions are weakly entangled, and the entanglement increases with decreasing DMI. We also find that the central spin is completely disentangled from the rest of the lattice, establishing a non-destructive way of detecting this type of skyrmion by local magnetization measurements. While neural networks are well suited to detect weakly entangled skyrmions with large DMI, they struggle to describe skyrmions in the small DMI regime due to nearly degenerate ground states and strong entanglement. In this paper, we propose a method to identify this regime and a technique to alleviate the problem. Finally, we analyze the workings of the neural network and explore its limits by pruning. Our work shows that neural network quantum states can be efficiently used to describe the quantum magnetism of large systems exceeding the size manageable in exact diagonalization by far.

Search for resonant production of high-mass photon pairs in proton-proton collisions at sqrt(s) = 8 and 13 TeV

description: A search for the resonant production of high-mass photon pairs is presented. The analysis is based on samples of proton-proton collision data collected by the CMS experiment at center-of-mass energies of 8 and 13 TeV, corresponding to integrated luminosities of 19.7 and 3.3 inverse femtobarns, respectively. The search focuses on spin-0 and spin-2 resonances with masses between 0.5 and 4 TeV and with widths, relative to the mass, between 1.4E-4 and 5.6E-2. Limits are set on scalar resonances produced through gluon-gluon fusion, and on Randall-Sundrum gravitons. A modest excess of events compatible with a narrow resonance with a mass of about 750 GeV is observed. The local significance of the excess is approximately 3.4 standard deviations. The significance is reduced to 1.6 standard deviations once the effect of searching under multiple signal hypotheses is considered. More data are required to determine the origin of this excess.

A brief history of gravitational wave research

description: For the benefit of the readers of this journal, the editors requested that we prepare a brief review of the history of the development of the theory, the experimental attempts to detect them, and the recent direct observations of gravitational waves (GWs). The theoretical ideas and disputes beginning with Einstein in 1916 regarding the existence and nature of GWs and the extent to which one can rely on the electromagnetic analogy, especially the controversies regarding the quadrupole formula and whether GWs carry energy, are discussed. The theoretical conclusions eventually received strong observational support from the binary pulsar. This provided compelling, although indirect, evidence for GWs carrying away energy--as predicted by the quadrupole formula. On the direct detection experimental side, Weber started more than 50 years ago. In 1966, his bar for GW detection reached a strain sensitivity of a few times 10^-16. His announcement of coincident signals (now considered spurious) stimulated many experimental efforts from room temperature resonant masses to cryogenic detectors and laser-interferometers. Now there are km-sized interferometric detectors (LIGO Hanford, LIGO Livingston, Virgo and KAGRA). Advanced LIGO first reached a strain sensitivity of the order of 10^-22. During their first 130 days of observation (O1 run), with the aid of templates generated by numerical relativity, they did make the first detections: two 5-sigma GW events and one likely event. Besides earth-based GW detectors, the drag-free sensitivity of the LISA Pathfinder has already reached to the LISA goal level, paving the road for space GW detectors. Over the whole GW spectrum (from aHz to THz) there are efforts for detection, notably the very-low-frequency band (pulsar timing array [PTA], 300 pHz-100 nHz) and the extremely-low (Hubble)-frequency (cosmic microwave background [CMB] experiment, 1 aHz-10 fHz).

description: We report a pressure study on electron doped SrFe$_{2-x}$Co$_x$As$_2$ by electrical-resistivity ($ρ$) and magnetic-susceptibility ($χ$) experiments. Application of either external pressure or Co substitution rapidly suppresses the spin-density wave ordering of the Fe moments and induces superconductivity in SrFe$_2$As$_2$. At $x=0.2$ the broad superconducting (SC) dome in the $T-p$ phase diagram exhibits its maximum $T_{c,{\rm max}}=20$ K at a pressure of only $p_{\rm max}\approx 0.75$ GPa. In SrFe$_{1.5}$Co$_{0.5}$As$_2$ no superconductivity is observed anymore up to 2.8 GPa. Upon increasing the Co concentration the maximum of the SC dome shifts toward lower pressure accompanied by a decrease in the value of $T_{c,{\rm max}}$. Even though, superconductivity is induced by both tuning methods, Co substitution leads to a much more robust SC state. Our study evidences that in SrFe$_{2-x}$Co$_x$As$_2$ both, the effect of pressure and Co-substitution, have to be considered in order to understand the SC phase-diagram and further attests the close relationship of SrFe$_2$As$_2$ and its sister compound BaFe$_2$As$_2$.
