A 149 minute periodicity underlies the X-ray flaring of Sgr A*

description: In a recent paper (Leibowitz 2017) I have shown that the 39 large X-ray flares of Sgr A* that were recorded by Chandra observatory in the year 2012, are concentrated preferably around tick marks of an equi-distance grid on the time axis. The period of this grid as found in L1 is 0.1033 days. In this work I show that the effect can be found among all the large X-ray flares recoded by Chandra and XMM-Newton along 15 years. The midpoints of all the 71 large flares recorded between the years 2000 and 2014 are also tightly grouped around tick marks of a grid with this period, or more likely, 0.1032 day. This result is obtained with a confidence level of at least 3.27σ and very likely of 4.62σ. I find also a possible hint that a similar grid is underlying IR flares of the object. I suggest that the pacemaker in the occurrences of the large X-ray flares of Sgr A* is a mass of the order of a low mass star or a small planet, in a slightly eccentric Keplerian orbit around the SMBH at the centre of the Galaxy. The radius of this orbit is about 6.6 Schwarzschild radii of the BH.

description: he expected increase in the penetration of renewables in the approaching decade urges the electricity market to introduce new products - in particular, flexible ramping products - to accommodate the renewables' variability and intermittency. CAISO and MISO are leading the design of the new products. However, it is not clear how such products may affect the electricity market. In this paper, we are specifically interested in assessing how the new products distort the optimal energy dispatch by comparing with the case without such products. The distortion may impose additional cost, which we term as the "distortion cost". Using a functional approach, we establish the relationship between the distortion cost and the key parameters of the new products, i.e., the up and down flexible ramping requirements. Such relationship yields a novel routine to efficiently construct the functions, which makes it possible to efficiently perform the minimal distortion cost energy dispatch while guaranteeing a given supply reliability level. Both theoretical analysis and simulation results suggest that smartly selecting the parameters may substantially reduce the distortion cost. We believe our approach can assist the ISOs with utilizing the ramping capacities in the system at the minimal distortion cost.

description: We employ the method of comparison equations to study the propagation of a massless minimally coupled scalar field on the Schwarzschild background. In particular, we show that this method allows us to obtain explicit approximate expressions for the radial modes with energy below the peak of the effective potential which are fairly accurate over the whole region outside the horizon. This case can be of particular interest, for example, for the problem of black hole evaporation.

description: Risk factors and production losses are reported for an outbreak of bovine respiratory disease (BRD] in stocker cattle in a southeastern US grass-based system. Beef calves purchased from livestock auctions arrived in 2 groups 1 week apart (n=133 and 77, respectively]. Cattle were mass- medicated with antibiotics and vaccinated 3 days after arrival, then commingled on ryegrass pasture. A daily BRD score (0-4] based on presence and severity of clinical signs was used to determine antibiotic treatment eligibility over the 150-day stocker phase. BRD morbidity and mortality were 61.9% and 12.9%, respectively. Cattle in arrival group 2 had a greater incidence density of BRD (rate ratio = 1.54,95% Cl: 1.07,2.22]. Odds for death were 5.0 times greater for cattle in arrival group 2 (95% Cl: 2.0,12.2] and 42.5 times greater for cattle diagnosed with BRD (95% Cl: 2.5,713.2]. Average daily gain was decreased 0.15 lb/day (0.07 kg/day] in cattle with BRD. Including death loss, calves with BRD gained an average of 64.1 lb (29.1 kg] less than unaffected calves over the stocker phase. Despite metaphylaxis and prompt identification of sick cattle, this BRD outbreak resulted in high morbidity, mortality, and production loss in a stocker cattle system.

Taxonomy of Modal Music with an Example of Modal Analysis of Ekmelic Music

subject: 190406 Music Composition

description: This summary briefly presents the classification system employed by the ethnomusicologists of the former Soviet Union and modern independent states formed after its fallout. Its principal advantage over the approach of Western ethnomusicology is the categorization of the intervallic typology and the identification of functions of musical intonations that constitute motifs and phrases of music. The value of this methodology is that it has been designed by collective efforts of thousands of musicologists who possessed both, etic and emic expertise in the analysis of music – and verified by the practice of arranging genuine folk music according to the principles identified by music theorists, and by the practice of playing the arranged music back to the indigenous audiences, while collecting their feedback. The effectiveness of this taxonomic approach is demonstrated in the example of ekmelic (based on a set of degrees that are indefinite in pitch) Yakut lullaby.

description: The frequency of a 700mW monolithic non-planar Nd:YAG ring laser (NPRO) depends with a large coupling coefficient (some MHz/mW) on the power of its laser-diode pump source. Using this effect we demonstrate the frequency stabilization of an NPRO to a frequency reference by feeding back to the current of its pump diodes. We achieved an error point frequency noise smaller than 1mHz/sqrt(Hz), and simultaneously a reduction of the power noise of the NPRO by 10dB without an additional power stabilization feed-back system.

description: Safety critical systems often have shutdown mechanisms to bring the system to a safe state in the event of a malfunction. We examine the use of ride-through, a technique to reduce the frequency of safety shutdowns by allowing small transient violations of safety rules. An illustrative example of enforcing a speed limit for an autonomous vehicle shows that using a rate-limited ride-through bound permits a tighter safety limit on speed than a fixed threshold without creating false alarm shutdowns. Adding state machines to select specific safety bounds based on vehicle state accommodates expected control system transients. Testing these principles on an autonomous utility vehicle resulted in improved detection of speed limit violations and shorter shutdown stopping distances without needing to increase the false alarm shutdown rate.

description: We present the design and implementation of RICH (Run-time Integer CHecking), a tool for efﬁciently detecting integer-based attacks against C programs at run time. C integer bugs, a popular avenue of attack and frequent programming error [1–15], occur when a variable value goes out of the range of the machine word used to materialize it, e.g. when assigning a large 32-bit int to a 16-bit short. We show that safe and unsafe integer operations in C can be captured by well-known sub-typing theory. The RICH compiler extension compiles C programs to object code that monitors its own execution to detect integer-based attacks. We implemented RICH as an extension to the GCC compiler and tested it on several network servers and UNIX utilities. Despite the ubiquity of integer operations, the performance overhead of RICH is very low, averaging about 5%. RICH found two new integer bugs and caught all but one of the previously known bugs we tested. These results show that RICH is a useful and lightweight software testing tool and run-time defense mechanism. RICH may generate false positives when programmers use integer overﬂows deliberately, and it can miss some integer bugs because it does not model certain C features.

description: Kempfcyclocypris gen. nov.
 Diagnosis. Carapace ovoid to subtriangular in lateral view. LV overlaps RV ventrally, anteriorly and posteriorly. Surface of carapace smooth, covered with long setae. Selvage peripheral anteriorly and posteriorly on both valves. A1 6-segmented. A 2 in male 5-segmented, penultimate segment divided, but t2 and t3 setae not transformed into sexual bristles. A2 sexually dimorphic: G1 and G3 claws in males reduced, z2 seta transformed into claw, z1 and z3 being seta-like. Swimming setae completely missing. Terminal segment of Md-palp elongated, but never longer than twice the width. Terminal segment of Mxl palp square. Prehensile palps very slightly asymmetrical. T2 with basal seta. Basal segment of T3 with “d2” seta. Setae “e”, “f” and “g” not short. Seta “h1” and “h2” subequally long. UR with all setae and claws present and normally developed. Hemipenis with lobes “a” and “b” well developed. Zenker organ with 7 whorls of spines. Genital field rounded.
 Type and only species. Kempfcyclocypris australis gen. et sp. nov.
 Etymology. The genus is named after Dr Eugen K. Kempf as a friendly acknowledgment of his contribution to ostracodology.
 Remarks and affinities. The appearance of the T3 and the prehensile palps clearly places this new genus in the subfamily Cyclocypridinae. It stands isolated from other representatives of the subfamily because of the 6-segmented A1 and the complete reduction of the swimming setae on the A2. It is, however, more closely related to Cyclocypris Brady & Norman, 1889 than to the other five genera of the subfamily. Cyclocypris and Kempfcyclocypris gen. nov. both have a long “g” seta on the T3, which is quite short in other genera. Like in Cyclocypris, males of Kempfcyclocypris do not have t2 and t3 setae on the A2 transformed into sexual bristles and the prehensile palps are less asymmetrical. Kempfcyclocypris is found only in eastern Australia, where it lives in the subterranean waters, which might explain the complete reduction of the swimming setae. The lack of the eye pigmentations and well developed sensory setae on both A1 and A2 are also indicators that this species is a true stygobiont.

description: Na atual Sociedade de Informação, por imperativos pessoais, sociais e políticos e até mesmo por exigência legal, ambicionando eliminar os conceitos de discriminação e de exclusão digitais, considera-se a acessibilidade e usabilidade digitais como uma necessidade básica para todos os utilizadores, evidenciando o desenvolvimento de ambientes e tecnologias que devem ser acessíveis. No entanto, em termos práticos, grupos específicos de indivíduos ficam excluídos dos benefícios desta nova Sociedade, com acesso condicionado, dado que enfrentam problemas a nível de acessibilidade e usabilidade muitas vezes complicados de superar. Assim sendo, justifica-se a preocupação de acesso universal às tecnologias e serviços disponibilizados, através dos ambientes digitais, como a Internet, visando a melhoria da qualidade de vida das pessoas. Neste contexto e de forma a divulgar e promover a área da Acessibilidade, a Revista de Ciências da Computação (RCC) da Universidade Aberta, lança este número especial (referente ao ano de 2015) sobre acessibilidade, denominado “Acessibilidade como motor de inclusão”. Agradecemos aos autores, aos membros do conselho editorial responsáveis pelas revisões científicas e aos revisores de língua portuguesa e inglesa. Para abrir o número especial Acessibilidade, o leitor terá acesso a um artigo sobre como fazer que os ecrãs táteis de dispositivos móveis sejam mais usáveis, usando métricas do modelo SUM.

description: We describe the general inflationary dynamics that can arise with a single, canonically coupled field where the inflaton potential is a 4-th order polynomial. This scenario yields a wide range of combinations of the empirical spectral observables, $n_s$, $r$ and $α_s$. However, not all combinations are possible and next-generation cosmological experiments have the ability to rule out all inflationary scenarios based on this potential. Further, we construct inflationary priors for this potential based on physically motivated choices for its free parameters. These can be used to determine the degree of tuning associated with different combinations of $n_s$, $r$ and $α_s$ and will facilitate treatments of the inflationary model selection problem. Finally, we comment on the implications of these results for the naturalness of the overall inflationary paradigm. We argue that ruling out all simple potentials would not necessarily imply that the inflationary paradigm itself was unnatural, but that this eventuality would increase the importance of building inflationary scenarios in the context of broader paradigms of ultra-high energy physics.

description: Density functional theory (DFT) calculations are used to investigate the electronic and magnetic structures of a two-dimensional (2D) monolayer Li$_{2}$N. It is shown that bulk Li$_{3}$N is a non-magnetic semiconductor. The non-spinpolarized DFT calculations show that $p$ electrons of N in 2D Li$_{2}$N form a narrow band at the Fermi energy $E_{\rm{F}}$ due to a low coordination number, and the density of states at the Fermi energy ($g(E_{\rm{F}}$)) is increased as compared with bulk Li$_{3}$N. The large $g(E_{\rm{F}}$) shows instability towards magnetism in Stoner's mean field model. The spin-polarized calculations reveal that 2D Li$_{2}$N is magnetic without intrinsic or impurity defects. The magnetic moment of 1.0\,$μ_{\rm{B}}$ in 2D Li$_{2}$N is mainly contributed by the $p_{z}$ electrons of N, and the band structure shows half-metallic behavior. {Dynamic instability in planar Li$_{2}$N monolayer is observed, but a buckled Li$_{2}$N monolayer is found to be dynamically stable.} The ferromagnetic (FM) and antiferromagnetic (AFM) coupling between the N atoms is also investigated to access the exchange field strength. {We found that planar (buckled) 2D Li$_{2}$N is a ferromagnetic material with Curie temperature $T_{c}$ of 161 (572) K.}

description: This paper aims to tackle two fundamental memory bottlenecks: limited off-chip bandwidth (bandwidth wall) and long access latency (memory wall). To achieve this goal, our approach exploits the inherent error resilience of a wide range of applications. We introduce an approximation technique, called Rollback-Free Value Prediction (RFVP). When certain safe-to-approximate load operations miss in the cache, RFVP predicts the requested values. However, RFVP never checks for or recovers from load value mispredictions, hence avoiding the high cost of pipeline flushes and re-executions. RFVP mitigates the memory wall by enabling the execution to continue without stalling for long-latency memory accesses. To mitigate the bandwidth wall, RFVP drops some fraction of load requests which miss in the cache after predicting their values. Dropping requests reduces memory bandwidth contention by removing them from the system. The drop rate then becomes a knob to control the tradeoff between performance/energy efficiency and output quality. For a diverse set of applications from Rodinia, Mars, and NVIDIA SDK, employing RFVP with a 14KB predictor per streaming multiprocessor (SM) in a modern GPU delivers, on average, 40% speedup and 31% energy reduction, with average 8.8% quality loss. With 10% loss in quality, the benefits reach a maximum of 2.4× speedup and 2.0× energy reduction. As an extension, we also evaluate RFVP’s latency benefits for a single core CPU. For a subset of the SPEC CFP 2000/2006 benchmarks that are amenable to safe approximation, RFVP achieves, on average, 8% speedup and 6% energy reduction, with 0.9% average quality loss.

description: We investigate the quantum Hall problem in the lowest Landau level in two dimensions, in the presence of an arbitrary number of $δ$-function potentials arranged in different geometric configurations. When the number of delta functions $N_δ$ is smaller than the number of flux quanta through the system ($N_ϕ$), there is a manifold of $(N_ϕ-N_δ)$ degenerate states at the original Landau level energy. We prove that the total Chern number of this set of states is +1 regardless of the number or position of the $δ$ functions. Furthermore, we find numerically that, upon the addition of disorder, this subspace includes a quantum Hall transition which is (in a well-defined sense) $\textit{quantitatively}$ the same as that for the lowest Landau level without $δ$-function impurities, but with a reduced number $N_ϕ' \equiv N_ϕ-N_δ$ of magnetic flux quanta. We discuss the implications of these results for studies of the integer plateau transitions, as well as for the many-body problem in the presence of electron-electron interactions.

Magnetic Reconnection: Sweet-Parker Versus Petschek

description: The two theories for magnetic reconnection, one of Sweet and Parker, and the other of Petschek, are reconciled by exhibiting an extra condition in that of Petschek which reduces his theory to that of Sweet and Parker, provided that the resistivity is constant in space. On the other hand, if the resistivity is enhanced by instabilities, then the reconnection rate of both theories is increased substantially, but Petschek's rate can be faster. A different formula from the usual one is presented for enhanced Petschek reconnection.

description: Computing systems use dynamic random-access memory (DRAM) as main memory. As prior works have shown, failures in DRAM devices are an important source of errors in modern servers. To reduce the effects of memory errors, error correcting codes (ECC) have been developed to help detect and correct errors when they occur. In order to develop effective techniques, including new ECC mechanisms, to combat memory errors, it is important to understand the memory reliability trends in modern systems. In this paper, we analyze the memory errors in the entire fleet of servers at Facebook over the course of fourteen months, representing billions of device days. The systems we examine cover a wide range of devices commonly used in modern servers, with DIMMs manufactured by 4 vendors in capacities ranging from 2 GB to 24 GB that use the modern DDR3 communication protocol. We observe several new reliability trends for memory systems that have not been discussed before in literature. We show that (1) memory errors follow a power-law, specifically, a Pareto distribution with decreasing hazard rate, with average error rate exceeding median error rate by around 55; (2) non-DRAM memory failures from the memory controller and memory channel cause the majority of errors, and the hardware and software overheads to handle such errors cause a kind of denial of service attack in some servers; (3) using our detailed analysis, we provide the first evidence that more recent DRAM cell fabrication technologies (as indicated by chip density) have substantially higher failure rates, increasing by 1.8 over the previous generation; (4) DIMM architecture decisions affect memory reliability: DIMMs with fewer chips and lower transfer widths have the lowest error rates, likely due to electrical noise reduction; (5) while CPU and memory utilization do not show clear trends with respect to failure rates, workload type can influence failure rate by up to 6.5, suggesting certain memory access patterns may induce more errors; (6) we develop a model for memory reliability and show how system design choices such as using lower density DIMMs and fewer cores per chip can reduce failure rates of a baseline server by up to 57.7%; and (7) we perform the first implementation and real-system analysis of page offlining at scale, showing that it can reduce memory error rate by 67%, and identify several real-world impediments to the technique.

description: We show how, in heterotic M-theory, an M5-brane in the 11-dimensional bulk may end on an ``M9-brane'' boundary, the M5-brane boundary being a Yang monopole 4-brane. This possibility suggests various novel 5-brane configurations of heterotic M-theory, in particular a static M5-brane suspended between the two M9-brane boundaries, for which we find the asymptotic heterotic supergravity solution.

description: We succeeded in the synthesis of high-Jc MgB2 bulks via high energy ball-milling of elemental Mg and B powder at ambient temperatures. Alternatively to longtime mechanical alloying technique, the mixed powder was ball-milled for only 1h and the completed reaction is achieved by subsequent annealing. The correlations among synthesis parameters, microstructures and superconducting properties in MgB2 bulks were investigated. Samples were characterized by XRD and SEM, and the magnetization properties were examined in a SQUID magnetometer. The high- Jc, approximately 1.7*106A/cm2(15K, 0.59T), and improved flux pinning were attribute to a large number of grain boundaries provided by small grain size.

description: As sensor networks gain traction and begin to scale, we will be increasingly faced with challenges associated with managing large-scale time-series data. In this paper, we present a cloud-to-edge partitioned architecture called Respawn that is capable of serving large amounts of time-series data from a continuously updating datastore with access latencies low enough to support interactive real-time visualization. Respawn targets sensing systems where resource-constrained edge node devices may only have limited or intermittent network connections linking them to a cloud-backend. The cloud-backend provides aggregate storage and transparent dispatching of data queries to edge node devices. Data is downsampled as it enters the system creating a multi-resolution representation capable of lowlatency range-base queries. Lower-resolution aggregate data is automatically migrated from edge nodes to the cloud-backend both for improved consistency and caching. In order to further mask latency from users, edge nodes automatically identify and migrate blocks of data that contain statistically interesting features. We show through simulation and micro-benchmarking that Respawn is able to run on ARM-based edge node devices connected to a cloud-backend with the ability to serve thousands of clients and terabytes of data with sub-second latencies.

description: The memory system is a fundamental performance and energy bottleneck in almost all computing systems. Recent system design, application, and technology trends that require more capacity, bandwidth, efficiency, and predictability out of the memory system make it an even more important system bottleneck. At the same time, DRAM technology is experiencing difficult technology scaling challenges that make the maintenance and enhancement of its capacity, energy-efficiency, and reliability significantly more costly with conventional techniques. In this article, after describing the demands and challenges faced by the memory system, we examine some promising research and design directions to overcome challenges posed by memory scaling. Specifically, we describe three major new research challenges and solution directions: 1) enabling new DRAM architectures, functions, interfaces, and better integration of the DRAM and the rest of the system (an approach we call system-DRAM co-design), 2) designing a memory system that employs emerging non-volatile memory technologies and takes advantage of multiple different technologies (i.e., hybrid memory systems), 3) providing predictable performance and QoS to applications sharing the memory system (i.e., QoS-aware memory systems). We also briefly describe our ongoing related work in combating scaling challenges of NAND flash memory
