description: Precise nature of MBL transitions in both random and quasiperiodic (QP) systems remains elusive so far. In particular, whether MBL transitions in QP and random systems belong to the same universality class or two distinct ones has not been decisively resolved. Here we investigate MBL transitions in one-dimensional ($d\!=\!1$) QP systems as well as in random systems by state-of-the-art real-space renormalization group (RG) calculation. Our real-space RG shows that MBL transitions in 1D QP systems are characterized by the critical exponent $ν\!\approx\!2.4$, which respects the Harris-Luck bound ($ν\!>\!1/d$) for QP systems. Note that $ν\!\approx\! 2.4$ for QP systems also satisfies the Harris-CCFS bound ($ν\!>\!2/d$) for random systems, which implies that MBL transitions in 1D QP systems are stable against weak quenched disorder since randomness is Harris irrelevant at the transition. We shall briefly discuss experimental means to measure $ν$ of QP-induced MBL transitions.

description: We discuss the extent to which models of Weakly Interacting Massive Particle (WIMP) Dark Matter (DM) at and above the electroweak scale can be probed conclusively in future high energy and astroparticle physics experiments. We consider simplified models with bino-like dark matter and slepton-like coannihilation partners, and find that perturbative models yield the observed relic abundance up to at least 10 TeV. We emphasise that coannihilation can either increase or decrease the dark matter relic abundance. We compute the sensitivity of direct detection experiments to DM-nucleus scattering, consider indirect detection bounds and estimate the sensitivity of future proton colliders to slepton pair production. We find that current and future experiments will be able to probe the Dirac DM models up to at least 10 TeV. However, current and future searches will not be sensitive to models of Majorana dark matter for masses above 2 or 4 TeV, for one or ten coannihilation partners respectively, leaving around 70 % of the parameter space unconstrained. This demonstrates the need for new experimental ideas to access models of coannihilating Majorana dark matter.

description: We have measured the 2 dimensional (2D) power spectrum of the Las Campanas Redshift Survey on scales between 30 and 200 Mpc (q_0=0.5, H_o=100h km sec^{-1} Mpc^{-1}). Such an analysis is more sensitive to structure on scales > 50 Mpc than a full 3 dimensional analysis given the geometry of the survey. We find a strong peak in the power spectrum at approximately 100 Mpc relative to the smooth continuum expected from the best fit Cold Dark Matter model (Probability is 2.5x10^{-4} with Omega h = 0.3 assuming a Gaussian random field). This signal is detected in two independent directions on the sky and has been identified with numerous structures visible in the survey which appear as walls and voids. Therefore, we conclude that there exists a significant increase in power on this scale and that such structures are common features in the local universe, z <= 0.2.

description: The squares of the three components of the spin-s operators sum up to $s(s+1)$. However, a similar relation is rarely satisfied by the set of possible spin projections onto mutually orthogonal directions. This has fundamental consequences if one tries to construct a hidden variable (HV) theory describing measurements of spin projections. We propose a test of local HV-models in which spin magnitudes are conserved. These additional constraints imply that the corresponding inequalities are violated within quantum theory by larger classes of correlations than in the case of standard Bell inequalities. We conclude that in any HV-theory pertaining to measurements on a spin one can find situations in which either HV-assignments do not represent a physical reality of a spin vector, but rather provide a deterministic algorithm for prediction of the measurement outcomes, or HV-assignments represent a physical reality, but the spin cannot be considered as a vector of fixed length.

description: Census returns are a critical source of information for governments globally. They underpin a wide spectrum of public planning including health, housing, work and education. Historically, census forms have captured names, places, dates, age, occupation, family structure, and religion. In more recent times, sexual orientation and ethnicity, queries that can be intrusive to vulnerable communities, have been added to the criteria, and for such reasons data security is of paramount importance. Most governments restrict access to individual census returns, presenting the data in aggregate report format. The Irish government is particularly strict, enforcing a statutory closure period of 100 years. An exception was made for the Irish 1911 census which were digitised and released for free online consultation in 2009 [1]. They are an excellent source for genealogists and historians alike but exist as separate digital siloes. This project uses an eXtreme Model-Driven Development (XMDD) environment to create linkages between both datasets. It will discuss the development process of the CensusIrl application and the process used in developing the matching algorithm used.We will discuss the census records and the data cleansing process used in creating the initial proof of concept application. We detail the different approaches to the development life-cycle of the application and describe the different utilises used in the sanitation of data points in the records and the match-making process.

description: Yb(Rh1-xCox)2Si2 is a model system to address two challenging problems in the field of strongly correlated electron systems: The first is the intriguing competition between ferromagnetic (FM) and antiferromagnetic (AFM) order when approaching a magnetic quantum critical point (QCP). The second is the occurrence of magnetic order along a very hard crystalline electric field (CEF) direction, i.e. along the one with the smallest available magnetic moment. Here, we present a detailed study of the evolution of the magnetic order in this system from a FM state with moments along the very hard c direction at x = 0.27 towards the yet unknown magnetic state at x = 0. We first observe a transition towards an AFM canted state with decreasing x and then to a pure AFM state. This confirms that the QCP in YbRh2Si2 is AFM, but the phase diagram is very similar to those observed in some inherently FM systems like NbFe2 and CeRuPO, which suggests that the basic underlying instability might be FM. Despite the huge CEF anisotropy the ordered moment retains a component along the c-axis also in the AFM state. The huge CEF anisotropy in Yb(Rh1-xCox)2Si2 excludes that this hard-axis ordering originates from a competing exchange anisotropy as often proposed for other heavy-fermion systems. Instead, it points to an order-by-disorder based mechanism.

description: A measurement is presented of the associated production of a single top quark and a W boson in proton-proton collisions at $\sqrt{s}=$ 13 TeV by the CMS Collaboration at the CERN LHC. The data collected corresponds to an integrated luminosity of 35.9 fb$^{-1}$. The measurement is performed using events with one electron and one muon in the final state along with at least one jet originated from a bottom quark. A multivariate discriminant, exploiting the kinematic properties of the events, is used to separate the signal from the dominant $\mathrm{t\overline{t}}$ background. The measured cross section of 63.1 $\pm$ 1.8 (stat) $\pm$ 6.4 (syst) $\pm$ 2.1 (lumi) pb is in agreement with the standard model expectation.

These partnerships take various forms, depending on the context in which they evolve; in some cases the extension services are also involved. Researchers fmm the four countries met in April 1997 to share their experience and dmw lessons from approximately two years of activities to promote such partnerships. This paper presents the finI ings from the workshop, drawing also on the authors' personal involvement in the four countries. The authors review: (0 the rationalefor a partnership; (ii) the approach taken in each of the four countries; and, OW the difficulties encountered, either on the side o f the pmducers' organisations or on the side o f the research institutes. Although it may be too early to make a final assessment of the extent to which producers' organisations have succeeded in making research institutes more client responsive, valuable lessons for producers' organisations, research institutes as well as donors and external agencies interested in promoting a productive partnership are already beginning to emerge. The experience o f these four countries is not unique: in a number of developing countries research and extension institutions have tried to establish partnership mechanisms with producers' organisations. These experiences have I' en documented IIInalysed elsewhere and the analysis presented here refers to work conducted by the Overseas Development Institute (ODD, the International Service for National Agricultural Research (ISNAR) and the Centre de Cooperation Internationale en Recherche Agronomique pour k Developpement-Systemes Agroalimentaires et Ruraux (CIRAD-SAR).

description: Dark excitons are of fundamental importance for a wide variety of processes in semiconductors, but are difficult to investigate using optical techniques due to their weak interaction with light fields. We reveal and characterize dark excitons injected by non-resonant pulsed excitation in a semiconductor microcavity structure containing InGaAs/GaAs quantum wells by monitoring their interactions with the bright lower polariton mode. We find a surprisingly long dark exciton lifetime of more than 20 ns which is longer than the time delay between two consecutive pulses. This creates a memory effect that we clearly observe through the variation of the time-resolved transmission signal. We propose a rate equation model that provides a quantitative agreement with the experimental data.

Local web buckling in tapered composite beams
Creators: name: Da Silva Vellasco, Pedro Colmar Goncalves
Publisher: name: Imperial College London
Year: 1992

description: Recent demand for very heavily serviced widespan office floors has led, as a natural development of the concept of haunched and tapered frames, to the use of composite flooring systems supported by tapered (varying web depth) beams. These systems are very attractive from an economic point of view, combining wide spans, rapid erection and easy access to services between the shallow parts of the beam and the ceiling below. One of the most pressing needs is for a better understanding of the local buckling behaviour of the relatively deep slender web at changes of slope in the lower flange, in particular at the slope change which occurs at the centre of a beam whose depth increases linearly from each support. In the past, with plate girders, this failure mechanism was less relevant than lateral torsional buckling. With the substantial top flange of a composite section, lateral buckling is less likely, and local buckling more likely to govern the design. The tapered beam sections are fabricated from plates by welding and are susceptible to imperfection effects and residual stresses. These phenomena may interact with the localized compressive stress field which is generated in the web at any slope change in the flange to cause local web buckling. The provision of local stiffening is technically feasible, but very expensive. The beam itself is produced fully automatically and the subsequent hand installation of stiffeners consumes man-hours out of all proportion to the weight of steel involved. The prime objective of the present study was to iucntify the relative importance of several parameters that influence the phenomenon, such as angle of taper, web thickness, flange area and others. For practical reasons, the experiments were executed at half-scale and the models simulated the concrete slab of the composite beam by a heavy steel top flange. Three tapered models have been tested with different web thicknesses i.e, 3, 5, and 7 millimetres. Three more specimens with different plastic neutral axis positions were also tested. An extensive parametric study has been made using a non-linear elastoplastic finite element program. This study covered practical ranges of the important parameters including the area of the tension flange and the position of the plastic neutral axis. Moment-rotation relations, peak moments and failure mechanisms have been predicted. Very good correlation was obtained between the results of the parametric study and the experiments. It has become apparent that in the great majority of practical cases it is possible to avoid the use of the expensive hand welded stiffeners. A design formulation has been developed to produce a very simple test of the need for stiffeners.

description: We propose and carry a detailed study of an observable sensitive to different mechanisms of minijet production. The class of observables measures how the transverse momenta of hadrons produced in association with various trigger objects are balanced as a function of rapidity. It is shown that the observables are sensitive to the model parameters relevant to the minijet production mechanisms: low-$p_{\rm T}$ cut-off regulating jet cross-section, transverse distribution of partons in protons, and parton distribution functions. We perform our test at different charge-particle multiplicities and collision energies. The MC models, which describe many features of the LHC data, are found to predict quite different results demonstrating high discriminating power of the proposed observables. We also review mechanisms and components of \sc{Herwig}, \sc{Pythia}, and \sc{Sherpa} Monte Carlo models relevant to the minijet production.

Defining the gastrointestinal microbiota in premature neonates: Its development and relation to necrotizing enterocolitis
Creators: name: Sim, Kathleen
Publisher: name: Imperial College London
Year: 2015

description: Background: Necrotizing enterocolitis (NEC) is an inflammatory bowel disease affecting premature infants. The disease can progress rapidly and is associated with high mortality. Early diagnosis can be difficult as the early manifestations of NEC can be very similar to sepsis. There is currently no pre-symptomatic screening method available. The aim of the work reported in this thesis was to identify microbial signatures in the gastrointestinal microbiota preceding NEC diagnosis in premature infants. Methods: Longitudinal (≥ daily) faecal samples and daily clinical data from throughout their neonatal intensive care unit stay were collected from 369 premature infants born at <32 weeks gestation over a two-year period. The faecal microbiota of 12 infants with definite/severe NEC, 8 with suspected NEC, and 44 control infants was characterised using next-generation sequencing of 16S ribosomal RNA gene regions. Clinical characteristics and operational taxonomical units (OTUs) that discriminated cases from controls were identified using logistic regression. Bacteria isolated from stored faecal samples underwent selective culture, and the resulting isolates were identified using Matrix-Assisted Laser Desorption Ionization Time-of-Flight. Isolates identified as Clostridium perfringens were additionally typed and screened for the presence of toxin genes. Results: Faecal samples collected from four NEC infants just prior to diagnosis were found to contain a higher abundance of a clostridial OTU compared to matched control samples. Culture investigation identified this OTU as Clostridium perfringens. No two Clostridium perfringens isolates were found to be identical, as determined by fluorescent amplified fragment length polymorphism. Infants with NEC who did not have an over-abundance of the clostridial OTU (n=7) prior to diagnosis had a faecal microbiota dominated by a Klebsiella OTU. Only one infant did not have an abundance of either the clostridial OTU or the Klebsiella OTU. The use of prolonged continuous positive airway pressure therapy with supplemental oxygen (CPAP oxygen) was also found to be associated with NEC risk. Conclusions: Two OTUs (Clostridium and Klebsiella) were identified at high levels in faecal samples collected from infants prior to NEC diagnosis. A screening tool incorporating these biomarkers with the duration of CPAP oxygen use may aid the clinician in making an early diagnosis of NEC.
Stateful data-parallel processing

Publisher: name: Imperial College London

description: Democratisation of data means that more people than ever are involved in the data analysis process. This is beneficial—it brings domain-specific knowledge from broad fields—but data scientists do not have adequate tools to write algorithms and execute them at scale. Processing models of current data-parallel processing systems, designed for scalability and fault tolerance, are stateless. Stateless processing facilitates capturing parallelisation opportunities and hides fault tolerance. However, data scientists want to write stateful programs—with explicit state that they can update, such as matrices in machine learning algorithms—and are used to imperative-style languages. These programs struggle to execute with high-performance in stateless data-parallel systems. Representing state explicitly makes data-parallel processing at scale challenging. To achieve scalability, state must be distributed and coordinated across machines. In the event of failures, state must be recovered to provide correct results. We introduce stateful data-parallel processing that addresses the previous challenges by: (i) representing state as a first-class citizen so that a system can manipulate it; (ii) introducing two distributed mutable state abstractions for scalability; and (iii) an integrated approach to scale out and fault tolerance that recovers large state—spanning the memory of multiple machines. To support imperative-style programs a static analysis tool analyses Java programs that manipulate state and translates them to a representation that can execute on SEEP, an implementation of a stateful data-parallel processing model. SEEP is evaluated with stateful Big Data applications and shows comparable or better performance than state-of-the-art stateless systems.

description: We explore the possibility that the Fast Radio Bursts (FRBs) are powered by magnetic reconnection in magnetars, triggered by Axion Quark Nugget (AQN) dark matter. In this model, the magnetic reconnection is ignited by the shock wave which develops when the nuggets' Mach number $M \gg 1$. These shock waves generate very strong and very short impulses expressed in terms of pressure $Δp/p\sim M^2$ and temperature $ΔT/T\sim M^2$ in the vicinity of (would be) magnetic reconnection area. We find that the proposed mechanism produces a coherent emission which is consistent with current data, in particular the FRB energy requirements, the observed energy distribution, the frequency range and the burst duration. Our model allows us to propose additional tests which future data will be able to challenge.

description: Unmanned Aerial Vehicles (UAVs) in Wireless Power Transfer (WPT)-assisted Internet of Things (IoT) systems face the following challenges: limited resources and suboptimal trajectory planning. Reinforcement learning-based trajectory planning schemes face issues of low search efficiency and learning instability when optimizing large-scale systems. To address these issues, we present an Attention-based UAV Trajectory Optimization (AUTO) framework based on the graph transformer, which consists of an Attention Trajectory Optimization Model (ATOM) and a Trajectory lEarNing Method based on Actor-critic (TENMA). In ATOM, a graph encoder is used to calculate the self-attention characteristics of all IoTDs, and a trajectory decoder is developed to optimize the number and trajectories of UAVs. TENMA then trains the ATOM using an improved Actor-Critic method, in which the real reward of the system is applied as the baseline to reduce variances in the critic network. This method is suitable for high-quality and large-scale multi-UAV trajectory planning. Finally, we develop numerous experiments, including a hardware experiment in the field case, to verify the feasibility and efficiency of the AUTO framework.
The Structure of Dark Matter Haloes in Hierarchical Clustering Models

description: We use a set of large cosmological N-body simulations to study the internal structure of dark matter haloes which form in scale-free models. We find that the radius r_178 corresponding to a mean interior overdensity of 178 accurately delineates the quasi-static halo interior from the surrounding infalling material, in agreement with the simple spherical collapse model. The interior velocity dispersion correlates with mass, again in good agreement with the spherical collapse model. Interior to the virial radius r_178, the spherical averaged density, circular velocity and velocity dispersion profiles are well fit by a simple 2-parameter analytic model proposed by Navarro etal (1995). This model has density going as 1/r at small radii, steepening to 1/r^3 at large radii, and fits our haloes to the resolution limit of the simulations. The two model parameters, scalelength and mass, are tightly correlated. Lower mass haloes are more centrally concentrated, and so have scalelengths which are a smaller fraction of their virial radius than those of their higher mass counterparts. This reflects the earlier formation times of low mass haloes. The haloes are moderately aspherical, with typical axial ratios 1:0.8:0.65 at their virial radii. These shapes are maintained by an anisotropic velocity dispersion tensor. The median value of the spin parameter is lambda=0.04, with a weak trend for lower lambda at higher halo mass. We also investigate how the halo properties depend on the algorithm used to identify them, using both friends-of-friends and spherical overdensity methods. We find that for groups selected at mean overdensities 100-400 by either method the properties are insensitive to how the haloes are selected, if the halo centre is taken as the position of the most bound particle

description: Strömungsmaschinen spielen in unserem alltäglichen Leben eine große Rolle. Einem unbestrittenen Nutzen steht neben einem großen Energieverbrauch auch eine erhebliche Schallemission gegenüber. Daher werden am Institut für Fluidsystemtechnik der Technischen Universität Darmstadt experimentelle Untersuchungen mit dem Ziel der akustischen und aerodynamischen Optimierung am Beispiel von Axialventilatoren an einem nach DIN 5136 konstruierten Prüfstand durchgeführt. Hier können primäre Maßnahmen zur Schallreduktion in Form von Schaufeldesign und Gehäuseoptimierung sowie sekundäre Maßnahmen wie Schalldämpfung durchgeführt werden. Die experimentellen Untersuchungen zeigen die aerodynamischen und akustischen Auswirkungen der Optimierung des Schaufeldesigns sowie den Einfluss des Schaufelspitzenspalts sowie einer konturierten Oberfläche eines Axialventilators. Zusätzlich zu den primären werden auch sekundäre Maßnahmen, wie die Installation eines Schalldämpfers über dem Rotor des Ventilators untersucht. Der Vortrag gibt einen Einblick in die betriebspunktabhängige Lärmemission sowie in Möglichkeiten der Lärmreduktion mit primären und sekundären Maßnahmen.

description: The Submillimetre Common-User Bolometer Array (SCUBA) is a new continuum camera operating on the James Clerk Maxwell Telescope (JCMT) on Mauna Kea, Hawaii. It consists of two arrays of bolometric detectors; a 91 pixel 350/450 micron array and a 37 pixel 750/850 micron array. Both arrays can be used simultaneously and have a field-of-view of approximately 2.4 arcminutes in diameter on the sky. Ideally, performance should be limited solely by the photon noise from the sky background at all wavelengths of operation. However, observations at submillimetre wavelengths are hampered by ``sky-noise'' which is caused by spatial and temporal fluctuations in the emissivity of the atmosphere above the telescope. These variations occur in atmospheric cells that are larger than the array diameter, and so it is expected that the resultant noise will be correlated across the array and, possibly, at different wavelengths. In this paper we describe our initial investigations into the presence of sky-noise for all the SCUBA observing modes, and explain our current technique for removing it from the data.

description: Mononchus zschokkei n. sp.
 Körpergestalt mäßig schlank, das Vorderende nur wenig verschmälert. Der papillentragende Teil des Kopfendes. unmerklich abgesetzt. Mundhöhle länglich, mit einem dorsalen Zahn, welcher stets im hinteren Drittel der Mundhöhle liegt und nach vorn gerichtet ist (Fig. 1). Kleine Zähnchen oft an der Basis der Mundhöhle vorkommend. Oesophagus nach hinten nur wenig erweitert, stets 1/ 4 der Gesamtlänge ausmachend. Xervenring vor der Mitte des Oesophagus gelegen. Weibliche Geschlechtsöffnung stets beim Beginn des letzten Körperdrittels liegend. Weibliche Geschlechtsorgane paarig symmetrisch, kurz; 1 bis 2 Eier im Uterus. Schwanz beim Weibchen und Männchen kurz, zugespitzt und nach der Bauchfläche gebogen (Fig. 2). Spicula mäßig schlank, mit centralem Verdickungsstreifen in ihrer distalen Hälfte, schwach gebogen. Accessorisches Stück zweiteilig, die Spicula umfassend, ähnlich wie bei Mononchus hrachyuris Bütschli (vgl. de Man, Onderzoekingen over vrij in de aarde levende Nematoden. Tijdschr. Nederl. Dierk. Ver. Deel 11, 1876, Taf. XIII, Fig. 51). Vor dem After eine Keihe von 21 kegelförmigen Papillen (Fig. 3), Cuticula in dieser Region schräg gestreift.
Länge: 2,2—3,2 mm.
 De Mansche Formel: α = 20-30, β = 4, ɣ = 20—24.
Vorkommen: In verschiedenen Gegenden der Schweizer Alpen, von 1500— 3400 m Höhe¹.
 Yerwandtschaft: Mon. zschokkei zeigt unterden zehn bis jetzt aus Europa bekannten Moìionchus- Arten einzig mit Moii. parvus de Man große Verwandtschaft, er unterscheidet sich von ihm hauptsächlich durch die Lage des dorsalen Zahnes und die Körpergröße. Ferner ist meines Wissens das Männchen von Mon. parvus unbekannt, während es bei Mon. zschokkei ziemlich häufig ist. (Auf 7 ♀ ♀ fallen etwa 2 ♂♂.) Von den aussereuropäischen Arten kämen, wie mir in liebenswürdiger Weise Herr Dr. J. G. de Man (Jerseke) mitteilte, nur Mon.  gymnolaimus  Cobb, Mon. sunilis Cobb und Mon. rex Cobb in Betracht, bei denen der dorsale Zahn ebenfalls an der Basis der Mundhöhle liegt; doch ist bei diesen 3 Arten der Schwanz lang(γ= 5— 7, und gleicht demjenigen von Mon. macrostoma Bast.
¹ Herrn cand. phil. W. Sehmassmann, welcher mir das der Beschreibung zugrunde liegende, von ihm neulich im Lünersee Rhätikon) gefundene Männchen überließ, spreche ich meinen herzlichen Dank aus. Ebenso bin ich Herrn Prof. Dr. C. Keller in Zürich für die Überlassung eines bisher undeterminierten, aus den Alpen stammenden Materiales zu großem Danke verpflichtet.
Es sei mir gestattet, diese Art meinem verehrten Lehrer, Herrn Prof. Dr. F. Zschokke, zu widmen.

Novel functions of NF-kB in cancer
Creators: name: Leow, Shi Chi
Publisher: name: Imperial College London

description: Cell proliferation involves an active reprogramming of cellular bioenergetic pathways towards glucose metabolism in order to meet the metabolic demands of anabolic growth. NF-κB family of transcription factors coordinate many of the signals that drive proliferation during immunity, inflammation and oncogenesis, but whether NF-κB plays a role in regulating the metabolic reprogramming necessary for cell division during these processes is unknown. In this study, we found that NF-κB functions as a central regulator of energy homeostasis by managing the balance between the utilization of glycolysis and mitochondrial respiration. NF-κB inhibition causes cellular reprogramming to aerobic glycolysis under basal conditions and induces necrosis on glucose deprivation. The metabolic rearrangement that results from NF-κB inhibition bypasses the requirement for tumour suppressor mutation in oncogenic transformation and hinders metabolic adaptation in cancer in vivo. We also identified a mechanism through which NF-κB regulates metabolism and demonstrated the physiological significance of the role of NF-κB in metabolic adaptation in normal and cancerous cells. We also investigated additional functions of NF-κB in oncogenesis mediated via the regulation of telomerase, a tumourigenic factor and downstream target of NF-κB. Telomerase is a ribonucleoprotein enzyme complex that elongates the telomeres of chromosomes to compensate for normal telomeric erosion which occurs at all chromosomes. In recent years, a growing body of evidence has suggested telomere-independent roles of telomerase. Therefore, we sought to investigate whether telomerase also modulated cancer cell metabolism. Our results demonstrate a previously unanticipated role for the catalytic subunit of telomerase, TERT, in regulating the Myc-dependent signalling program which provides one explanation for the role of sustained telomerase activity in human cancer. Given that in cancer, Myc is often a passive conduit for upstream oncogenic flux including that of aberrant NF-κB activity, and global inhibition of both Myc and NF-κB could lead to undersirable toxicities, our data might lead to the development of novel combinatorial cancer treatment modalities.

Coronal Gamma Ray Bursts as the sources of Ultra High Energy Cosmic Rays?
Creators: name: Vietri, Mario
Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I consider the possibility that Ultra High Energy Cosmic Rays are accelerated in Gamma Ray Bursts located in the Galactic corona, thus circumventing the problem raised by Greisen--Zatsepin--Kuz'min cutoff. The acceleration of UHECRs could occur in the pulsars which, in the coronal GRB model, produce them: the same parameters that permit fitting GRBs' observations in the model of Podsiadlowski, Rees and Ruderman (1995) lead to an estimate of the highest achievable energies corresponding to that of the Bird et al (1994) event, and to very low luminosities in cosmic rays. I show that, if the observations of Milgrom and Usov (1995a) are confirmed, the extragalactic GRBs' model for the acceleration of UHECRs is untenable, but the same constraint does not apply to the coronal model. Also, I show that the efficiency of particle acceleration needs be much smaller (and less demanding) than in cosmological models of GRBs. Uncertainties remain about the ensuing cosmic ray spectral distribution. I also briefly discuss observational strategies to distinguish between the two possibilities.

UNCA: A Neutrosophic-Based Framework for Robust Clustering and Enhanced Data Interpretation

description: Accurately representing the complex linkages and inherent uncertainties included in huge datasets is still a major difficulty in the field of data clustering. We address these issues with our proposed Unified Neutrosophic Clustering Algorithm (UNCA), which combines a multifaceted strategy with Neutrosophic logic to improve clustering performance. UNCA starts with a full-fledged similarity examination via a λ-cutting matrix that filters meaningful relationships between each two points of data. Then, we initialize centroids for Neutrosophic K-Means clustering, where the membership values are based on their degrees of truth, indeterminacy and falsity. The algorithm then integrates with a dynamic network visualization and MST (Minimum Spanning Tree) so that a visual interpretation of the relationships between the clusters can be clearly represented. UNCA employs SingleValued Neutrosophic Sets (SVNSs) to refine cluster assignments, and after fuzzifying similarity measures, guarantees a precise clustering result. The final step involves solidifying the clustering results through defuzzification methods, offering definitive cluster assignments. According to the performance evaluation results, UNCA outperforms conventional approaches in several metrics: it achieved a Silhouette Score of 0.89 on the Iris Dataset, a Davies-Bouldin Index of 0.59 on the Wine Dataset, an Adjusted Rand Index (ARI) of 0.76 on the Digits Dataset, and a Normalized Mutual Information (NMI) of 0.80 on the Customer Segmentation Dataset. These results demonstrate how UNCA enhances interpretability and resilience in addition to improving clustering accuracy when contrasted with Fuzzy C-Means (FCM), Neutrosophic C-Means (NCM), as well as Kernel Neutrosophic C-Means (KNCM). This makes UNCA a useful tool for complex data processing tasks

description: The Submillimetre Common-User Bolometer Array (SCUBA) is one of a new generation of cameras designed to operate in the submillimetre waveband. The instrument has a wide wavelength range covering all the atmospheric transmission windows between 300 and 2000 microns. In the heart of the instrument are two arrays of bolometers optimised for the short (350/450 microns) and long (750/850 microns) wavelength ends of the submillimetre spectrum. The two arrays can be used simultaneously, giving a unique dual-wavelength capability, and have a 2.3 arc-minute field of view on the sky. Background-limited performance is achieved by cooling the arrays to below 100 mK. SCUBA has now been in active service for over a year, and has already made substantial breakthroughs in many areas of astronomy. In this paper we present an overview of the performance of SCUBA during the commissioning phase on the James Clerk Maxwell Telescope (JCMT).
