description: A well-known problem in data science and machine learning is {\em linear regression}, which is recently extended to dynamic graphs. Existing exact algorithms for updating the solution of dynamic graph regression require at least a linear time (in terms of $n$: the size of the graph). However, this time complexity might be intractable in practice. In the current paper, we utilize {\em subsampled randomized Hadamard transform} and \textsf{CountSketch} to propose the first sublinear update time randomized algorithms for regression of general dynamic graphs. Suppose that we are given a $n\times d$ matrix embedding $\mathbf M$ of the graph, where $d \ll n$ and $\mathbf M$ has certain properties. Let $r$ be the number of samples required by subsampled randomized Hadamard transform for a $1\pm ε$ approximation, which is a sublinear of $n$. Our first algorithm supports edge insertion and edge deletion and updates the approximate solution in $O(rd)$ time. Our second algorithm is based on \textsf{CountSketch} and supports edge insertion, edge deletion, node insertion and node deletion. It updates the approximate solution in $O(qd)$ time, where $q=O\left(\frac{d^2}{ε^2} \log^6(d/ε) \right)$.

description: We present timing and spectral analysis of data from an observation of the High Mass X-ray Binary pulsar 4U 1907+09 with the LAXPC instrument onboard AstroSat. The light curve consisted of a flare at the beginning of the observation, followed by persistent emission. The pulsar continues to spin down, and the pulse profile is found to be double-peaked up to 16 keV with the peaks separated by a phase of $\sim0.45$. Significant energy dependence of the pulse profile is seen with diminishing amplitude of the secondary peak above 16 keV, and increasing amplitude of the main peak upto 40 keV and a sharp decline after that. We confirm earlier detections of the Cyclotron Resonance Scattering Feature (CRSF) in 4U 1907+09 at $\sim 18.5\pm 0.2$ keV in the phase-averaged spectrum with a high detection significance. An intensity resolved spectral analysis of the initial flare in the light curve shows that the CRSF parameters do not change with a change in luminosity by a factor of 2.6. We also performed pulse phase-resolved spectral analysis with ten independent phase bins. The energy and the strength of the cyclotron line show pulse phase dependence that is in agreement with previous measurements. Two features from the current observation: different energy dependence of the two pulse peaks and a strong CRSF only around the secondary peak, both indicate a deviation from a dipole geometry of the magnetic field of the neutron star, or complex beaming pattern from the two poles.

Abundance gradients in spiral disks: is the gradient inversion at high redshift real?

description: We compute the abundance gradients along the disk of the Milky Way by means of the two-infall model: in particular, the gradients of oxygen and iron and their temporal evolution. First, we explore the effects of several physical processes which influence the formation and evolution of abundance gradients. They are: i) the inside-out formation of the disk, ii) a threshold in the gas density for star formation, iii) a variable star formation efficiency along the disk, iv) radial flows and their speed, and v) different total surface mass density (gas plus stars) distributions for the halo. We are able to reproduce at best the present day gradients of oxygen and iron if we assume an inside-out formation, no threshold gas density, a constant efficiency of star formation along the disk and radial gas flows. It is particularly important the choice of the velocity pattern for radial flows and the combination of this velocity pattern with the surface mass density distribution in the halo. Having selected the best model, we then explore the evolution of abundance gradients in time and find that the gradients in general steepen in time and that at redshift z~3 there is a gradient inversion in the inner regions of the disk, in the sense that at early epochs the oxygen abundance decreases toward the Galactic center. This effect, which has been observed, is naturally produced by our models if an inside-out formation of the disk and and a constant star formation efficiency are assumed. The inversion is due to the fact that in the inside-out formation a strong infall of primordial gas, contrasting chemical enrichment, is present in the innermost disk regions at early times. The gradient inversion remains also in the presence of radial flows, either with constant or variable speed in time, and this is a new result.

description: The red-giant branch (RGB) in globular clusters is extended to larger brightness if the degenerate helium core loses too much energy in "dark channels." Based on a large set of archival observations, we provide high-precision photometry for the Galactic globular cluster M5 (NGC 5904), allowing for a detailed comparison between the observed tip of the RGB with predictions based on contemporary stellar evolution theory. In particular, we derive 95% confidence limits of $g_{ae}<4.3\times10^{-13}$ on the axion-electron coupling and $μ_ν<4.5\times10^{-12}\,μ_{\rm B}$ (Bohr magneton $μ_{\rm B}=e/2m_e$) on a neutrino dipole moment, based on a detailed analysis of statistical and systematic uncertainties. The cluster distance is the single largest source of uncertainty and can be improved in the future.

description: The interaction of two lasers with a difference frequency near that of the ambient plasma frequency produces beat waves that can resonantly accelerate thermal electrons. These beat waves can be used to drive electron current and thereby embed magnetic fields into the plasma [D. R. Welch et al., Phys. Rev. Lett. 109, 225002 (2012)]. In this paper, we present two-dimensional particle-in-cell simulations of the beat-wave current-drive process over a wide range of angles between the injected lasers, laser intensities, and plasma densities. We discuss the application of this technique to the magnetization of dense plasmas, motivated in particular by the problem of forming high-beta plasma targets in a standoff manner for magneto-inertial fusion. The feasibility of a near-term experiment embedding magnetic fields using lasers with micron-scale wavelengths into a $\sim 10^{18}$-cm$^{-3}$-density plasma is assessed.

description: Catalogues and other records of aurora-borealis events were used to study the long-term spatial and temporal variation of these phenomena in the period from 1700 to 1905 in the Northern Hemisphere. For this purpose, geographic and geomagnetic coordinates were assigned to approximately 27 000 auroral events with more than 80 000 observations. They were analysed separately in three large-scale areas: i) Europe and North Africa, ii) North America, and iii) Asia. There was a clear need to fill some gaps existing in the records so as to have a reliable proxy of solar activity, especially during the 18th century. In order to enhance the long-term variability, an 11-year smoothing window was applied to the data. Variations in the cumulative numbers of auroral events with latitude (in both geographic and geomagnetic coordinates) were used to discriminate between the two main solar sources: coronal mass ejections and high-speed streams from coronal holes. The characteristics of the associated aurorae correlate differently with the solar-activity cycle.

description: Photorespiration is an energy wasteful process in plants that serves as a way to recover fixed carbon as a result of the oxygenase activity of Rubisco. The observations on plants having C3, C3-C4 intermediate, C4-like, and C4 photosynthesis shows that the gradual relocation of the photorespiratory cycle from the mesophyll cells to the bundle sheath cells triggered the evolution of C4 plants. Engineering C3 crops, such as rice, to perform C4 photosynthesis would provide the necessary increase in their yield potential needed to cope with growing human population. One of the core enzymes of the photorespiratory cycle is the Glycine Decarboxylase Complex (GDC). GDC along with serine-hydroxymethyl transferase converts two glycine molecules into one serine molecule with the concomitant release of carbon dioxide and ammonia. To trigger C4 phenomena in rice, an artificial microRNA (amiRNA) was designed to silence the GDCH expression in mesophyll cells using maize PEP-carboxylase promoter. Stopping the activity of the GDC in mesophyll cells would lead in an increase in glycine concentration that can be transported to bundle sheath cells where it can be decarboxylated, and act as a secondary CO2 concentrating mechanism. GDCH is encoded by a small gene family composed of Os02g07410, Os06g45670, and Os10g37180. The amiRNA was designed to target Os10g37180 isoform which is highly expressed in leaves and photosynthetic tissues. Analysis of homozygous transgenic plants showed no expression of the Os10g37180 gene in the leaves using RT-PCR and western blot. Reduction of Os10g37180 expression affected photosynthetic activity and growth of transgenic plants however the plants can still tolerate ambient CO2 condition. Among the other isoforms only Os02g07410 were still expressed in the leaves of the transgenic plants which presents the possibility that it could complement the function of Os10g37180 in leaves. Current experiment is being done to target Os02g07410 using the same amiRNA technology into the Os10g37180 knockdown plant.

description: Deep Reinforcement Learning (DRL) has shown a dramatic improvement in decision-making and automated control problems. Consequently, DRL represents a promising technique to efficiently solve many relevant optimization problems (e.g., routing) in self-driving networks. However, existing DRL-based solutions applied to networking fail to generalize, which means that they are not able to operate properly when applied to network topologies not observed during training. This lack of generalization capability significantly hinders the deployment of DRL technologies in production networks. This is because state-of-the-art DRL-based networking solutions use standard neural networks (e.g., fully connected, convolutional), which are not suited to learn from information structured as graphs. In this paper, we integrate Graph Neural Networks (GNN) into DRL agents and we design a problem specific action space to enable generalization. GNNs are Deep Learning models inherently designed to generalize over graphs of different sizes and structures. This allows the proposed GNN-based DRL agent to learn and generalize over arbitrary network topologies. We test our DRL+GNN agent in a routing optimization use case in optical networks and evaluate it on 180 and 232 unseen synthetic and real-world network topologies respectively. The results show that the DRL+GNN agent is able to outperform state-of-the-art solutions in topologies never seen during training.

description: We consider two types of random networks grown in blocks. Hooking networks are grown from a set of graphs as blocks, each with a labelled vertex called a hook. At each step in the growth of the network, a vertex called a latch is chosen from the hooking network and a copy of one of the blocks is attached by fusing its hook with the latch. Bipolar networks are grown from a set of directed graphs as blocks, each with a single source and a single sink. At each step in the growth of the network, an arc is chosen and is replaced with a copy of one of the blocks. Using Pólya urns, we prove normal limit laws for the degree distributions of both networks. We extend previous results by allowing for more than one block in the growth of the networks and by studying arbitrarily large degrees.

description: Recent research reveals that deep learning is an effective way of solving high dimensional Hamilton-Jacobi-Bellman equations. The resulting feedback control law in the form of a neural network is computationally efficient for real-time applications of optimal control. A critical part of this design method is to generate data for training the neural network and validating its accuracy. In this paper, we provide a survey of existing algorithms that can be used to generate data. All the algorithms surveyed in this paper are causality-free, i.e., the solution at a point is computed without using the value of the function at any other points. At the end of the paper, an illustrative example of optimal feedback design using deep learning is given.

description: Millimeter-wave (mmW) radars are being increasingly integrated in commercial vehicles to support new Adaptive Driver Assisted Systems (ADAS) for its ability to provide high accuracy location, velocity, and angle estimates of objects, largely independent of environmental conditions. Such radar sensors not only perform basic functions such as detection and ranging/angular localization, but also provide critical inputs for environmental perception via object recognition and classification. To explore radar-based ADAS applications, we have assembled a lab-scale frequency modulated continuous wave (FMCW) radar test-bed (https://depts.washington.edu/funlab/research) based on Texas Instrument's (TI) automotive chipset family. In this work, we describe the test-bed components and provide a summary of FMCW radar operational principles. To date, we have created a large raw radar dataset for various objects under controlled scenarios. Thereafter, we apply some radar imaging algorithms to the collected dataset, and present some preliminary results that validate its capabilities in terms of object recognition. Our code is available at https://github.com/Xiangyu-Gao/mmWave-radar-signal-processing-and-microDoppler-classification.

description: Hybrid games are models which combine discrete, continuous, and adversarial dynamics. Game logic enables proving (classical) existence of winning strategies. We introduce constructive differential game logic (CdGL) for hybrid games, where proofs that a player can win the game correspond to computable winning strategies. This is the logical foundation for synthesis of correct control and monitoring code for safety-critical cyber-physical systems. Our contributions include novel static and dynamic semantics as well as soundness and consistency.

description: Smoking habits of Americans have changed substantially over the past several decades, in large part because of the increasing knowledge and publicity regarding health hazards of tobacco consumption. It is to be expected that physicians and other health professionals would be in the vanguard of smoking reduction, and previous studies show that whereas in the 1950s more than 50 percent of physicians smoked, by 1975 the prevalence had dropped to about 20 percent. We present here a portrait of smoking habits in 11,324 physicians, 2,892 dentists, and 44,568 nurses enrolled in Cancer Prevention Study II, a cohort study of 1.2 million US men and women initially surveyed in 1982. Our data show, for example, that 16.7 percent of physicians in this sample were current smokers. Smoking prevalence was slightly lower in dentists (14.1 percent) but considerably greater in nurses (23.6 percent of female nurses and 41.3 percent of male nurses). Male doctors who continue to smoke consume more cigarettes per day than female doctors who are current smokers. These data are generally consistent with population studies, and reinforce the notion that health professionals should be exemplars with respect to health behaviors such as smoking.

description: We report the discovery of two long-period giant planets from the Anglo-Australian Planet Search. HD 154857c is in a multiple-planet system, while HD 114613b appears to be solitary. HD 114613b has an orbital period P=10.5 years, and a minimum mass m sin i of 0.48 Jupiter masses; HD 154857c has P=9.5 years and m sin i=2.6 Jupiter masses. These new data confirm the planetary nature of the previously unconstrained long-period object in the HD 154857 system. We have performed detailed dynamical stability simulations which show that the HD 154857 two-planet system is stable on timescales of at least 100 million years. These results highlight the continued importance of "legacy" surveys with long observational baselines; these ongoing campaigns are critical for determining the population of Jupiter analogs, and hence of those planetary systems with architectures most like our own Solar system.

description: Researchers have become increasingly interested in nanoparticles made from plants because of their stability and large surface area. In the current study, iron oxide and iron dioxide nanoparticles were synthesized using aerial parts of the E. tirucalli as a reducing agent. The nanoparticles were analyzed using various techniques, including Ultraviolet-visible spectroscopy, Fourier Transform Infrared spectroscopy, X-ray diffractometer, X-ray photoelectron spectroscopy, X-ray energy dispersive spectroscopy, Scanning electron Microscopy, and Transmission Electron Microscopy. The nanoparticles were then investigated for their antiproliferative effect against MCF-7, SK-BR-3, MDA-MB231, and Vero cell lines. The results confirmed the formation of FeO and FeO2 nanoparticles by color change and a UV absorbance peak between 220–390 nm. EDS analysis showed traces of Fe and O, while TEM confirmed the nanoparticle size of 100 nm. FTIR showed a peak at 514 nm. The FeO-RT NPs demonstrated over 80% antiproliferative activity against the MCF-7 cell line at a concentration of 10 μg/mL. while doxorubicin, FeO-RT NPs, and DCM extract showed similar activity against the MDA-MB231 cell line at 10 and 1 g/mL concentrations. However, Vero and SK-BR-3 cell lines showed decreased antiproliferative activity. This study highlights the environmentally friendly use and safe application of iron oxide NPs in cancer therapy.
Music Analysis and the Social Life of Jazz Recordings

description: In recent years, music theorists have taken an increased interest in jazz
and produced more and more analytical studies of improvised jazz solos.
For many involved in jazz research, this has been an encouraging sign.
Most obviously, it has signaled the respectability jazz has attained within
the musicological disciplines since the mid-1980s as a music worthy of detailed
criticism. It has also expanded the range and depth of jazz scholarship,
providing new points of entry into the field for emerging scholars
who may otherwise have pursued a different course. More importantly,
however, the growing sophistication of contemporary analytical methods
has enriched our understanding of the nature of jazz improvisation,
enabling us to ask better questions about the music than in the past.

description: Game Logic is an excellent setting to study proofs-about-programs via the interpretation of those proofs as programs, because constructive proofs for games correspond to effective winning strategies to follow in response to the opponent's actions. We thus develop Constructive Game Logic which extends Parikh's Game Logic (GL) with constructivity and with first-order programs a la Pratt's first-order dynamic logic (DL). Our major contributions include: 1) a novel realizability semantics capturing the adversarial dynamics of games, 2) a natural deduction calculus and operational semantics describing the computational meaning of strategies via proof-terms, and 3) theoretical results including soundness of the proof calculus w.r.t. realizability semantics, progress and preservation of the operational semantics of proofs, and Existence Properties on support of the extraction of computational artifacts from game proofs. Together, these results provide the most general account of a Curry-Howard interpretation for any program logic to date, and the first at all for Game Logic.

An Exploration of Culture and the Conceptions of Science in Elementary Indigenous Classrooms

Subjects: Uncategorized

description: This research explored how science is perceived by teachers, examined factors that may influence perceptions, and how perceptions may inform teaching practice, with the possibility of teachers embedding or drawing on their indigenous knowledge (IK). The study is qualitative and was conducted in the context of elementary Dayak teachers in Indonesia. During the nine months of fieldwork at two elementary schools with 6 teachers and 38 students as the participants, the data was gathered through three stages: (1) unstructured interviews, (2) classroom observation followed by video-stimulated recall interviews and (3) lesson-study modification. Analysis suggested that: (1) teachers’ views about science were constructed within the prevailing Dayak culture and impact the development of scientific literacy (SL), (2) teachers’ conceptual understanding was influenced by the process of cross-linguistic transfer between science terms and ordinary language, (3) the curriculum demand and teachers’ perceptions about science might have marginalised and impacted teachers’ teaching confidence, leading to a high dependence on textbook presentation, (4) teachers used IK for contextual learning strategies, (5) teaching practice seemed to be influenced by teachers’ perception on indigenous pedagogy and the lack of access to science-related resources. The contribution of this study has been to confirm the challenges and opportunities of teaching science in the context of indigenous schools and discussed for the first time the role of IK literacy, particularly in preparing science content in ways that are more relevant to students. In addition, this project revealed a new understanding of the way IK carved teachers’ perceptions and provided a pedagogical framework that is likely to promote learning. Providing teachers’ voices, this study offered insights into the design of professional development programs as well as calling practitioners and policy-makers to consider cultural barriers in indigenous science classrooms.
New Technology and Tools to Enhance Collaborative Video Analysis in Live ‘Data Sessions’

description: The live ‘data session’ is arguably a significant collaborative practice amongst a group of co-present colleagues that has sustained the fermentation of emerging analyses of interactional phenomena in ethnomethodological conversation analysis for several decades. There has not, however, been much in the way of technological innovation since its inception. In this article, I outline how the data session can be enhanced (a) by using simple technologies to support the ‘silent data session’, (b) by developing software tools to present, navigate and collaborate on new types of video data in novel ways using immersive virtual reality technologies, and (c) by supporting distributed version control to nurture the freedom and safety to collaborate synchronously and asynchronously on the revision of a common transcript used in a live data session. Examples of real cases, technical solutions and best practices are given based on experience. The advantages and limitations of these significant enhancements are discussed in methodological terms with an eye to future developments.

description: We experimentally investigated the optical responses of a superconducting niobium resonator. It was found that, with increasing radiation power, the resonance frequency increases monotonically below around 500 mK, decreases monotonically above around 1 K and exhibits a nonmonotonic behavior at around 700 mK. These observations show that one can operate the irradiated resonator in three temperature regimes, depending on whether two-level system (TLS) effects or kinetic inductance effects dominate. Furthermore, we found that the optical responses at ultra-low temperatures can be qualitatively regarded as a photon-induced thermalization effect of TLSs, which could be utilized to achieve thermal sensitive photon detections.

description: For a finite ring $R$, not necessarily commutative, we prove that the category of $\text{VIC}(R)$-modules over a left Noetherian ring $\mathbf{k}$ is locally Noetherian, generalizing a theorem of the authors that dealt with commutative $R$. As an application, we prove a very general twisted homology stability for $\text{GL}_n(R)$ with $R$ a finite noncommutative ring.

description: It is not our practice to raise complaints against a negative review report. We believe in peer refereeing and we respect it, whatever its content and consequences. However, in the case of our latest grant application (project named ‘The Time Machine’) we find it necessary to express our astonishment at the motivations with which our request for funding was turned down. Your main objection appears to be that our project is ‘philosophically interesting’ but ‘practically useless’, by which you mean that the project ‘has no potential for applications.’ We do not quite think that the main criterion for judging the scientific value of a project should be its practical usefulness, but never mind that. Let us agree that usefulness is a relevant criterion, especially when large amounts of money are involved. Why should that be a reason to turn down our project? Quite frankly, we cannot think of a project with better application potential than ours. Certainly you have noticed that our suggestions for practical applications of the time machine did not include any uses that could result in an alteration of the natural course of history. As a matter of fact, we believe that no such alteration is logically possible. According to our project, it is logically possible to visit the past but not to modify the past. No time traveler can undo what has been done or do what has not been done. So the logic is safe.
Strength of the $E_{\text{cm}} = 1113$ keV resonance in $^{20}${Ne}$(p, γ)^{21}${Na}

description: The $^{20}$Ne$(p, γ)^{21}$Na reaction is the starting point of the NeNa cycle, which is an important process for the production of intermediate mass elements. The $E_{\text{cm}} = 1113$ keV resonance plays an important role in the determination of stellar rates for this reaction since it is used to normalize experimental direct capture yields at lower energies. The commonly accepted strength of this resonance, $ωγ= 1.13 \pm 0.07$ eV, has been misinterpreted as the strength in the center-of-mass frame when it is actually the strength in the laboratory frame. This has motivated a new measurement of the $E_{\text{cm}} = 1113$ keV resonance strength in $^{20}$Ne$(p, γ)^{21}$Na using the DRAGON recoil mass spectrometer. The DRAGON result, $0.972 \pm 0.11$ eV, is in good agreement with the accepted value when both are calculated in the same frame of reference.

description: Background: Despite the high comorbidity between acquired brain injury (ABI) and mental health/addictions (MHA), best practices for treating MHA disorders in individuals with ABI have not been established and it remains unclear on how to best support this population. The DECISION–MAP project aims to systematically map evidence addressing MHA interventions for people with ABI, while identifying knowledge gaps to guide future research in these fields. Methods: Evidence mapping methodology will be used to identify and organize empirical evidence and trial registries on MHA interventions for persons with ABI. PsycINFO, SCOPUS, MEDLINE, the Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials), Web of Science, and CINAHL will be searched. Relevant articles will be included and systematically organized into DECISION–MAP. The primary outcome of this proposed study is the development of a web-based, interactive, and user-friendly platform that knowledge users can utilize to locate and engage with up-to-date evidence on interventions for concurrent ABI and MHA. The secondary outcome will be a narrative description of the included articles and results from the evidence gap analysis.

description: The increasing number of traffic accidents caused by drowsy drivinghas drawn much attention for detecting driver’s status and alarming drowsydriving. Existing research indicates that the changes in the physiological char?acteristics can reflect fatigue status, particularly brain activities. Nowadays, theresearch on brain science has made significant progress, such as the analysis ofEEG signal to provide technical supports for real world applications. In thispaper, we analyze drivers’ EEG data sets based on the self-adjusting DynamicTime Dependency (DTD) method for detecting drowsy driving. The proposedmodel, i.e. SEGAPA, incorporates the time window moving method and clusterprobability distribution for detecting drivers’ status. The preliminary experi?mental results indicates the efficiency of the proposed method.

description: In a recent article S. Gharibian [\href{http://dx.doi.org/10.1103/PhysRevA.86.042106}{Phys. Rev. A {\bf 86}, 042106 (2012)}] has conjectured that no two qubit separable state of rank greater than two could be maximally non classical (defined to be those which have normalized geometric discord $1/4$) and asked for an analytic proof. In this work we prove analytically that among the subclass of $X$ states, there is a unique (up to local unitary equivalence) maximal separable state of rank two. Partial progress has been made towards the general problem and some necessary conditions have been derived.

description: Time interleaved analog-to-digital conversion (TIADC) based on parallelism is an effective way to meet the requirement of the ultra-fast waveform digitizer beyond Gsps. Different methods to correct the mismatch errors among different analog-to-digital conversion channels have been developed previously. To overcome the speed limitation in hardware design and to implement the mismatch correction algorithm in real time, this paper proposes a fully parallel correction algorithm. A 12-bit 1-Gsps waveform digitizer with ENOB around 10.5 bit from 5 MHz to 200 MHz is implemented based on the real-time correction algorithm.

description: Deep learning techniques have shown their success in medical image segmentation since they are easy to manipulate and robust to various types of datasets. The commonly used loss functions in the deep segmentation task are pixel-wise loss functions. This results in a bottleneck for these models to achieve high precision for complicated structures in biomedical images. For example, the predicted small blood vessels in retinal images are often disconnected or even missed under the supervision of the pixel-wise losses. This paper addresses this problem by introducing a long-range elastic interaction-based training strategy. In this strategy, convolutional neural network (CNN) learns the target region under the guidance of the elastic interaction energy between the boundary of the predicted region and that of the actual object. Under the supervision of the proposed loss, the boundary of the predicted region is attracted strongly by the object boundary and tends to stay connected. Experimental results show that our method is able to achieve considerable improvements compared to commonly used pixel-wise loss functions (cross entropy and dice Loss) and other recent loss functions on three retinal vessel segmentation datasets, DRIVE, STARE and CHASEDB1.
