Given a host graph G and a pattern graph H, the induced subgraph isomorphism problem is to decide whether G contains an induced subgraph that is isomorphic to H. We study the time complexity of induced subgraph isomorphism problems where the pattern graph is fixed. Nešetřil and Poljak gave an O(nkω) time algorithm that decides the induced subgraph isomophism problem for any 3k vertex pattern graph (the universal algorithm), where ω(p, q, r) is the exponent of np × nq and nq × nr matrix multiplication and ω = ω(1, 1, 1). Algorithms that are faster than the universal algorithm are known only for a finite number of pattern graphs. In this paper, we obtain algorithms that are faster than the universal algorithm for infinitely many pattern graphs. More specifically, we show that there exists a family of pattern graphs (H3k)k≥0 such that the induced subgraph isomorphism problem for H3k (on 3k vertices) has a O(nω(k,k−1,k) time algorithm when k = 2r, r ≥ 1. Note that for the currently known best matrix multiplication algorithms ω(k, k − 1, k) k (k-vertex paths) when 5 ≤ k ≤ 9 and Ck (k-vertex cycles) for k ∈ {5, 7, 9}. In particular, we obtain O(nω) time algorithms for P5 and C5 that are optimal under reasonable hardness assumptions. 2. Faster than universal algorithm for all pattern graphs except Kk (k-vertex cliques) and Ik (k-vertex independent sets) for k ≤ 8. 3. Combinatorial algorithms (algorithms that do not use fast matrix multiplication) that take O(nk−2) time for Pk and Ck. 4. Combinatorial algorithms that take O(nk−1) time for all pattern graphs except Kk and Ik for k. Our notion of reduction can also be used to argue about hardness of detecting patterns within our framework. Since this method is used (explicitly or implicitly) by many existing algorithms (including the universal algorithm) for solving subgraph isomorphism problems, these hardness results show the limitations of existing methods. We obtain the following relative hardness results: 1. Induced subg

Context. Recent observations suggest that planets formation starts early, in protostellar disks of ≤ 105 yrs, which are characterized by strong interactions with the environment, e.g., through accretion streamers and molecular outflows. Aims. To investigate the impact of such phenomena on disk physical and chemical properties it is key to understand what chemistry planets inherit from their natal environment. Methods. In the context of the ALMA Large Program (LP) Fifty AU STudy of the chemistry in the disk/envelope system of Solar-like protostars (FAUST), we present observations on scales from ∼1500 au to ∼60 au of H2CO, HDCO, and D2CO towards the young planet-forming disk IRS 63. Results. H2CO probes the gas in the disk as well as in a large scale streamer (∼ 1500 au) impacting onto the South-East (SE) disk side. We detect for the first time deuterated formaldehyde, HDCO and D2CO, in a planet-forming disk, and HDCO in the streamer that is feeding it. This allows us to estimate the deuterium fractionation of H2CO in the disk: [HDCO]/[H2CO]∼ 0.1 − 0.3 and [D2CO]/[H2CO]∼ 0.1. Interestingly, while HDCO follows the H2CO distribution in the disk and in the streamer, the distribution of D2CO is highly asymmetric, with a peak of the emission (and [D]/[H] ratio) in the SE disk side, where the streamer crashes onto the disk. In addition, D2CO is detected in two spots along the blue- and red-shifted outflow. This suggests that: (i) in the disk, HDCO formation is dominated by gas-phase reactions similarly to H2CO, while (ii) D2CO was mainly formed on the grain mantles during the prestellar phase and/or in the disk itself, and is at present released in the gas-phase in the shocks driven by the streamer and the outflow. Conclusions. These findings testify on the key role of streamers in the build-up of the disk both concerning the final mass available for planet formation and its chemical composition.

IEEE/ACM International Conference on Technical Debt (TechDebt)

Technical debt management entails the quantification of principal and interest. In our previous work we had introduced a framework for calculating the Technical Debt Breaking Point (TD-BP), which is a point in time where the accumulated interest becomes larger than the principal; thus the debt of the company is no longer sustainable after this point in time. In this paper, we instantiate this framework and validate its ability to assess the breaking point of source code modules in an industrial setting. The results of the validation suggest that the calculated TD-BP is strongly correlated to experts' opinion on the sustainability of modules, and that it can accurately rank components, based on their maintenance difficulty.

Forest fire is one of the environmental problems in terms of economically and ecologically detrimental. The number hotspot of forest fires in Indonesia has become increasing dramatically in September 2019 with 16178 hotspots that caused hazardous haze. The hazardous haze has disturbed about 1.04 million and 6.5 million people in Pekanbaru City and Riau Province subsequently. Hence, the development of early warning systems may provide effective strategic information plus accurate prediction results tailored for forest fire prevention and control. Weather data can be used as the main source for analyzing forest fires. This study aims to predict forest fire in Riau, Indonesia. This study has used 1733 weather data in five years (2015-2019). The forest fire prediction models were developed by using two supervised machine-learning techniques namely Decision Tree (DT) and Bayesian Network (BN). The experimental result shows that BN outperforms DT with accuracy rate and RMSE value in pairs of 99.62% and 0.076, and 93.18% and 0.244 subsequently. Despite its low performance, DT able to extract the main factors that caused the forest and land fires efficiently. Thus, it can be concluded that the prediction model using BN has the potential to be used effectively but still has plenty of room for improvement.

Water is one of the cornerstones in human survival and a necessity for socio-economic development. Due to that, effective management of water demand especially in the rural area becomes vital. The objective of this study is to conduct a water demand study at Kenyir Lake, Terengganu using Micro-Component Analysis (MCA). Water demand is also being assessed using National Water Services Commissions (SPAN) Guidelines, parallel to water guidelines applied for Malaysia's building and comparison purposes. MCA considers detailed parameters of water use activities of the respective study area, whereas SPAN Guidelines use the fixed values of average daily water demand according to the type of building. The available dataset was interpreted using MCA and SPAN Guidelines, resulting in total daily water demand at Kenyir Lake of 1249.8 m3 and 1254.1 m3 respectively. Estimated water demand using SPAN Guidelines is found to be higher than MCA. The value differences occur due to the average water demand value in the guideline that is limited to a specific type of premises and does not comply with premises there. The estimated water demand can be adopted as a baseline for water companies and the government to improve the demand and supply of water.

Aims. Methanol is a ubiquitous species commonly found in the molecular interstellar medium. It is also a crucial seed species for the build-up of chemical complexity in star forming regions. Thus, understanding how its abundance evolves during the star formation process and whether it enriches the emerging planetary system is of paramount importance. Methods. We used new data from the ALMA Large Program FAUST (Fifty AU STudy of the chemistry in the disc/envelope system of solar protostars) to study the methanol line emission towards the [BHB2007] 11 protobinary system (sources A and B), where a complex structure of filaments connecting the two sources with a larger circumbinary disc has previously been detected. Results. Twelve methanol lines have been detected with upper energies in the [45-537]K range along with one 13CH3OH transition and one methyl formate (CH3OCHO) line blended with one of the methanol transitions. The methanol emission is compact (FWHM∼ 0.500) and encompasses both protostars, which are separated by only 0.200 (28 au). In addition, the overall methanol line emission presents three velocity components, which are not spatially resolved by our observations. Nonetheless, a detailed analysis of the spatial origin of these three components suggests that they are associated with three different spatial regions, with two of them close to 11B and the third one associated with 11A. A radiative transfer analysis of the methanol lines gives a kinetic temperature of [100-140] K, an H2 volume density of 106-107 cm-3 and column density of a few 1018 cm-2 in all three components with a source size of ∼0.15''. Thus, this hot and dense gas is highly enriched in methanol with an abundance as high as 10-5. Using previous continuum data, we show that dust opacity can potentially completely absorb the methanol line emission from the two binary objects. Conclusions. Although we cannot firmly exclude other possibilities, we suggest that the detected hot methanol is res

Volunteered geographical information (VGI) is an increasing source of data for many applications. In order to explore some of these sources of data, an algorithm was conceived and implemented in the ExploringVGI platform enabling the collection of georeferenced data from collaborative projects that provide an Application Programming Interface (API). This paper presents a preliminary study to evaluate the consistency and relevance of VGI extracted from Flickr platform for emergency mitigation and municipal management. The study carried out was based on data extraction and analysis with keywords related to emergency events ("Accident", "Flood" and "Fire apartment"), and municipal management ("Graffiti" and "Homeless") in four European cities (Frankfurt, Lisbon, London, and Rome). The proposed approach sets up a region of interest on a map, selects one or more keywords for the search, and carries out a search using the Flickr API. Data detected and extracted were then loaded into a database and further analysed to verify whether they were consistently obtained through consecutive searches at different locations. A statistical analysis performed on data collected for each case provided us with: the total number of data collected for each keyword and location;their relevance in terms of search goal;and the quality of the associate geolocation of the post. Results obtained illustrate the effectiveness of the approach when applied to different scenarios, which contributes to assess the role that VGI available on the Web may have in different events depending on the specific context of a geolocation/keyword(s) combination. © Authors 2018.

Large and complex optical quantum states are a key resource for fundamental science and applications such as quantum communications, information processing, and metrology. In this context, cluster states are a particularly important class because they enable the realization of universal quantum computers by means of the so-called 'one-way' scheme, where processing operations are performed through measurements on the state. While two-level (i.e. qubit) cluster states have been realized thus far, further boosting this computational resource by increasing the number of particles comes at the price of significantly reduced coherence time and detection rates, as well as increased sensitivity to noise. In contrast, the realization of d-level (with d > 2) cluster states offers the possibility to increase quantum resources without changing the number of particles, enables the implementation of efficient computational protocols, as well as coincides with a reduction in the noise sensitivity of the states. Here, we experimentally realize, characterize, and perform one-way processing operations on three-level, four-partite cluster states formed by two photons in the time and frequency domain. We make use of a unique approach based on integrated photonic chips and optical fiber communications components, enabling scalable, deterministic new functionalities. © 2019 IEEE.

This letter presents a search for narrow, high-mass resonances in the Zγ final state with the Z boson decaying into a pair of electrons or muons. The s=13 TeV pp collision data were recorded by the ATLAS detector at the CERN Large Hadron Collider and have an integrated luminosity of 140 fb⁻¹. The data are found to be in agreement with the Standard Model background expectation. Upper limits are set on the resonance production cross section times the decay branching ratio into Zγ. For spin-0 resonances produced via gluon–gluon fusion, the observed limits at 95% confidence level vary between 65.5 fb and 0.6 fb, while for spin-2 resonances produced via gluon–gluon fusion (or quark–antiquark initial states) limits vary between 77.4 (76.1) fb and 0.6 (0.5) fb, for the mass range from 220 GeV to 3400 GeV. © 2023 The Author(s)
