description: We present observations at 250, 350, and 500 um of the nearby galaxy cluster Abell 3112 (z=0.075) carried out with BLAST, the Balloon-borne Large Aperture Submillimeter Telescope. Five cluster members are individually detected as bright submillimetre sources. Their far-infrared SEDs and optical colours identify them as normal star-forming galaxies of high mass, with globally evolved stellar populations. They all have B-R colours of 1.38+/-0.08, transitional between the blue, active population and the red, evolved galaxies that dominate the cluster core. We stack to determine the mean submillimetre emission from all cluster members, which is determined to be 16.6+/-2.5, 6.1+/-1.9, and 1.5+/-1.3 mJy at 250, 350, and 500 um, respectively. Stacking analyses of the submillimetre emission of cluster members reveal trends in the mean far-infrared luminosity with respect to cluster-centric radius and Ks-band magnitude. We find that a large fraction of submillimetre emission comes from the boundary of the inner, virialized region of the cluster, at cluster-centric distances around R_500. Stacking also shows that the bulk of the submillimetre emission arises in intermediate-mass galaxies (L

description: The bright Type II-plateau supernova (SN) 2004dj occurred within the young, massive stellar cluster Sandage-96 in a spiral arm of NGC 2403. New multi-wavelength observations obtained with several ground-based and space-based telescopes are combined to study the radiation from Sandage-96 after SN 2004dj faded away. Sandage-96 started to dominate the flux in the optical bands starting September 2006 (~800 d after explosion). The optical fluxes are equal to the pre-explosion ones within the observational uncertainties. An optical Keck spectrum obtained ~900 d after explosion shows the dominant blue continuum from the cluster stars shortward of 6000 Åas well as strong SN nebular emission lines redward. The integrated spectral energy distribution (SED) of the cluster has been extended into the ultraviolet region by archival XMM-Newton and new Swift observations, and compared with theoretical models. The outer parts of the cluster have been resolved by the Hubble Space Telescope, allowing the construction of a color-magnitude diagram. The fitting of the cluster SED with theoretical isochrones results in cluster ages between 10--40 Myr, depending on metallicity and the model family. The isochrone fitting indicates that the resolved part of the cluster has a bimodal age distribution: a younger population at ~10--16 Myr, and an older one at ~32--100 Myr which is similar to the age distribution of the nearby field stars. These stars may have been captured from the field during the cluster formation. The young age of Sandage-96 suggest 12 < M_prog < 20 M_\odot as the most probable mass range for the progenitor of SN 2004dj. This is consistent with, but perhaps slightly higher than, most of the other Type II-plateau SN progenitor masses determined so far.

description: The low-energy excitations of cuprate superconductors exhibit various characteristics that differ from those of simple Bogoliubov quasiparticles for pure d_{x^2-y^2}-wave superconductors. Here we report experimental studies of spatially resolved quasiparticle tunnelling spectra of hole- and electron-type cuprate superconductors that manifest direct evidences for the presence of competing orders (COs) in the cuprates. In contrast to conventional type-II superconductors that exhibit enhanced local density of states (LDOS) peaking at zero energy near the centre of field-induced vortices, the vortex-state LDOS of YBa_2Cu_3O_{7-δ} (Y-123) and La_{0.1}Sr_{0.9}CuO_2 (La-112) remains suppressed inside the vortex core, with pseudogap (PG)-like features at an energy larger (smaller) than the superconducting (SC) gap Δ_{SC} in Y-123 (La-112). Energy histograms of the SC and PG features reveal steady spectral shifts from SC to PG with increasing magnetic field H. These findings may be explained by coexisting COs and SC: For hole-type cuprates with PG above T_c, the primary CO gap (V_{CO}) is larger than Δ_{SC} and the corresponding COs are charge/pair-density waves with wave-vectors parallel to (π,0)/(0,π). For electron-type cuprates without PG above T_c, V_{CO} is smaller than Δ_{SC} and the CO wave-vector is along (π,π). This CO scenario may be extended to the ARPES data to consistently account for the presence (absence) of Fermi arcs in hole- (electron)-type cuprates. Fourier transformation of the vortex-state LDOS in Y-123 further reveals multiple sets of energy-independent wave-vectors due to field-enhanced pair- and spin-density waves. These results imply important interplay of SC with low-energy collective excitations.

description: Security has become ubiquitous in every domain today as newly emerging malware pose an ever-increasing perilous threat to systems. Consequently, honeypots are fast emerging as an indispensible forensic tool for the analysis of malicious network traffic. Honeypots can be considered to be traps for hackers and intruders and are generally deployed complimentary to Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) in a network. They help system administrators perform a rigorous analysis of external and internal attacks on their networks. They are also used by security firms and research labs to capture the latest variants of malware. However, honeypots would serve a slightly different purpose in our proposed system. We intend to use honeypots for generating and broadcasting instant cures for new and unknown malware in a network. The cures which will be in the form of on-the-fly anti-malware signatures would spread in a fashion that is similar to the way malware spreads across networks. The most striking advantage of implementing this technology is that an effective initial control can be exercised on malware. Proposed system would be capable of providing cures for new fatal viruses which have not yet been discovered by prime security firms of the world.

description: With an increasing complexity of nanoscopic systems and the modeling thereof, new theoretical tools are needed for a reliable calculation of complex systems with strong electronic correlations. To this end, we propose a new approach based on the recently introduced dynamical vertex approximation. We demonstrate its reliability already on the one-particle vertex (i.e., dynamical mean field theory) level by comparison with the exact solution. Modeling a quantum point contact with 110 atoms, we show that the contact becomes insulating already before entering the tunneling regime due to a local Mott-Hubbard transition occurring on the atoms which form the point contact.

description: Using a high resolution hydrodynamical cosmological simulation of the formation of a massive spheroidal galaxy we show that elliptical galaxies can be very compact and massive at high redshift in agreement with recent observations. Accretion of stripped in-falling stellar material increases the size of the system with time and the central concentration is reduced by dynamical friction of the surviving stellar cores. In a specific case of a spheroidal galaxy with a final stellar mass of $1.5 \times 10^{11} M_{\odot}$ we find that the effective radius $r_e$ increases from $0.7 \pm 0.2 \rm kpc$ at z = 3 to $r_e = 2.4 \pm 0.4 \rm kpc$ at z = 0 with a concomitant decrease in the effective density of an order of magnitude and a decrease of the central velocity dispersion by approximately 20% over this time interval. A simple argument based on the virial theorem shows that during the accretion of weakly bound material (minor mergers) the radius can increase as the square of the mass in contrast to the usual linear rate of increase for major mergers. By undergoing minor mergers compact high redshift spheroids can evolve into present-day systems with sizes and concentrations similar to observed local ellipticals. This indicates that minor mergers may be the main driver for the late evolution of sizes and densities of early-type galaxies.

description: Cosmic strings are predicted to form kinks and cusps that travel along the string at close to the speed of light. These disturbances are radiated away as highly beamed gravitational waves that produce a burst like pulse as the cone of emission sweeps past an observer. Gravitational wave detectors such as the Laser Interferometer Space Antenna (LISA) and the Laser Interferometer Gravitational wave Observatory (LIGO) will be capable of detecting these bursts for a wide class of string models. Such a detection would illuminate the fields of string theory, cosmology, and relativity. Here we develop template based Markov Chain Monte Carlo (MCMC) techniques that can efficiently detect and characterize the signals from cosmic string cusps. We estimate how well the signal parameters can be recovered by the advanced LIGO-Virgo network and the LISA detector using a combination of MCMC and Fisher matrix techniques. We also consider joint detections by the ground and space based instruments. We show that a parallel tempered MCMC approach can detect and characterize the signals from cosmic string cusps, and we demonstrate the utility of this approach on simulated data from the third round of Mock LISA Data Challenges (MLDCs).

description: Even though people in our contemporary, technological society are depending on communication, our understanding of the underlying laws of human communicational behavior continues to be poorly understood. Here we investigate the communication patterns in two social Internet communities in search of statistical laws in human interaction activity. This research reveals that human communication networks dynamically follow scaling laws that may also explain the observed trends in economic growth. Specifically, we identify a generalized version of Gibrat's law of social activity expressed as a scaling law between the fluctuations in the number of messages sent by members and their level of activity. Gibrat's law has been essential in understanding economic growth patterns, yet without an underlying general principle for its origin. We attribute this scaling law to long-term correlation patterns in human activity, which surprisingly span from days to the entire period of the available data of more than one year. Further, we provide a mathematical framework that relates the generalized version of Gibrat's law to the long-term correlated dynamics, which suggests that the same underlying mechanism could be the source of Gibrat's law in economics, ranging from large firms, research and development expenditures, gross domestic product of countries, to city population growth. These findings are also of importance for designing communication networks and for the understanding of the dynamics of social systems in which communication plays a role, such as economic markets and political systems.

Functional brain networks underlying autobiographical event simulation
Creators: name: Momeni, Ava
Publisher: name: University of British Columbia
Year: 2024

description: Functional magnetic resonance imaging (fMRI) studies typically explore the blood-oxygen-level-dependent (BOLD) signal underlying discrete cognitive processes that occur over milliseconds to a few seconds. However, autobiographical cognition is a protracted process and requires fMRI tasks with longer trials to capture the temporal dynamics of the underlying brain networks. In the current study, we provide an updated analysis of the fMRI data obtained from a published autobiographical event simulation task, with a slow-event-related design (34-second trials), that involved participants recalling past events, imagining past/future events, and completing a semantic association control task. Both versions of the analytical approach, called Principal Component Analysis for fMRI (fMRI-CPCA), used to derive the brain networks involved in the autobiographical event simulation task resulted in four brain networks. Two networks, the Default Mode network, which activated during the autobiographical event simulation conditions but deactivated in the semantic association control condition, and the Multiple Demand network, which peaked early in the trials when external focus to solve the task was required, partially reproduced and extended the previously published results. Two networks, the Maintaining Internal Attention network, which activated when participants had to direct their focus internally to engage in autobiographical event simulation and semantic association, and the Response network, which activated when participants had to make motor responses, were novel and provided new information about the BOLD changes underlying autobiographical event simulation. Overall, our findings reveal that the DMN is not uniquely involved in autobiographical event simulation as it coactivates with the MAIN. However, these two networks do not have redundant functions as in the semantic association control condition, the DMN deactivated while the MAIN activated. Thus, our results highlight that the MAIN consistently shows activation during all periods of maintaining attention to internal mental representations, whereas the DMN shows activation during the simulation of internal events that take one’s own perspective – a process unlikely to be engaged during semantic association. The identification of additional networks by fMRI-CPCA demonstrates how different analytical approaches can provide complementary information and, ultimately, lead to more refined cognitive interpretations of task-based fMRI data.

Thermomechanical pulp fines as additives for 3D printing filaments
Creators: name: Chen, Siwei
Publisher: name: University of British Columbia
Year: 2024

description: To enhance the sustainability of fused deposition modeling (FDM) 3D printing filaments, wood materials are emerging as eco-friendly fillers in thermoplastics. This study introduced thermomechanical pulp (TMP) fines, a by-product from industrial pulping process, as fillers in polylactic acid (PLA) for 3D printing filaments. To address the limited compatibility between hydrophilic fines and hydrophobic PLA matrices, three strategies were adapted to prevent fine agglomeration and enhance filler-matrix adhesion. Mechanical treatment using ball milling, chemical modification by (2-Dodecen-1-yl)succinic anhydride (DDSA) esterification, and additives of coupling agents (maleic-anhydride grafted polypropylene [MAPP] and maleic-anhydride grafted PLA [MAPLA]) were employed and systematically studied. Tensile, rheology, thermal analysis and printability tests were conducted to evaluate the effect of incorporating fines and the efficacy of above three methods. Further characterization by scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM) were used to analyze fracture surfaces and understand fine distribution. The PLA/TMP fines composites exhibited higher tensile modulus compared to pure PLA (increased from 792 MPa to 1084 MPa with a 20% w/w loading content), while it lowered the tensile strength, elongation at break and toughness. Compared to untreated TMP fines at the same loading level (20% w/w), the composites with ball-milled (Bm) fines presented a 33% increase in tensile strength, a 115% increase in elongation at break, and a 192% increase in toughness due to smaller fine particles and improved dispersion. DDSA-treated fines showed increased hydrophobicity but limited mechanical improvement. By adding MAPP or MAPLA into the PLA/TMP fines composites, both groups exhibited toughening effects, especially with MAPP. Combining MAPP with ball milling further enhanced the composites (10 % w/w untreated TMP fines in PLA) with an increase of elongation at break by 139% and toughness by 170%, demonstrating the modifications’ synergistic benefits. The PLA/TMP fines composites exhibited pronounced shear thinning behavior and reduced complex viscosity, storage modulus, and loss modulus at higher frequencies compared to PLA. While those incorporating ball-milled fines closely mirrored the rheological characteristics of pure PLA. Particularly, PLA mixed with 10% Bm fines demonstrated excellent printability, offering a sustainable 3D printing material.

description: We present results of an extensive morphological, spectroscopic, and photometric study of the galaxy population of MACS J0025.4$-$1225 (z=0.586), a major cluster merger with clear segregation of dark and luminous matter, to examine the impact of mergers on galaxy evolution. Based on 436 galaxy spectra obtained with Keck DEIMOS, we identified 212 cluster members within 4 Mpc of the cluster centre, and classified them using three spectroscopic types; we find 111 absorption-line, 90 emission-line (including 23 e(a) and 11 e(b)), and 6 E+A galaxies. The fraction of absorption(emission)-line galaxies is a monotonically increasing(decreasing) function of both projected galaxy density and radial distance to the cluster center. More importantly, the 6 observed E+A cluster members are all located between the dark-matter peaks of the cluster and within ~0.3Mpc radius of the X-ray flux peak, unlike the E+A galaxies in other intermediate-redshift clusters which are usually found to avoid the core region. In addition, we use Hubble Space Telescope imaging to classify cluster members according to morphological type. We find the global fraction of spiral and lenticular galaxies in MACS J0025 to be among the highest observed to date in clusters at z>0.5. The observed E+A galaxies are found to be of lenticular type with Sersic indices of ~2, boosting the local fraction of S0 to 70 per cent between the dark-matter peaks. Combing the results of our analysis of the spatial distribution, morphology, and spectroscopic features of the galaxy population, we propose that the starburst phase of these E+A galaxies was both initiated and terminated during the first core-passage about 0.5--1Gyr ago, and that their morphology has already been transformed into S0 due to ram pressure and/or tidal forces near the cluster core. By contrast, ongoing starbursts are observed predominantly in infalling galaxies, and thus appears to be unrelated to the cluster merger.

description: We present a detailed theoretical discussion of the effects of ubiquitous laser noise on cooling and the coherent dynamics in opto-mechanical systems. Phase fluctuations of the driving laser induce modulations of the linearized opto-mechanical coupling as well as a fluctuating force on the mirror due to variations of the mean cavity intensity. We first evaluate the influence of both effects on cavity cooling and find that for a small laser linewidth the dominant heating mechanism arises from intensity fluctuations. The resulting limit on the final occupation number scales linearly with the cavity intensity both under weak and strong coupling conditions. For the strong coupling regime, we also determine the effect of phase noise on the coherent transfer of single excitations between the cavity and the mechanical resonator and obtain a similar conclusion. Our results show that conditions for optical ground state cooling and coherent operations are experimentally feasible and thus laser phase noise does pose a challenge but not a stringent limitation for opto-mechanical systems.

description: In this poster the progress of the COPIED study is visualised as of the 29th of october 2021. This poster was presented at the first symposium of the Dutch Parkinson's Scientists.  Circumventing obstacles in thinking in Parkinson's disease A considerable number of people with Parkinson's suffer from obstacles in thinking, often even before the diagnosis. These include problems with attention and concentration, memory, speed of thinking and acting, keeping an overview and planning, stimulus processing and carrying out (double) tasks. There are as yet no scientifically substantiated aids for circumventing such obstacles. In the meantime, people with Parkinson's are incredibly creative in finding detours so that they can still carry out their daily activities. It is these detours that the researchers of the COPIED study have collected via 1:1 interviews & focus groups, validated with a questionnaire, and are currently transforming into a self-help tool that will be tested by the research participants before unleashing it to the Dutch Parkinson's community. Peer-2-Peer The COPIED study is a peer-2-peer research project. It is led by people with Parkinson's (patient researchers), harvests the detours that PwPD and their loved ones take to circumvent their obstacles in thinking, and subsequently shares such bundled detours with the community that provided the input.

Distinguishing between Planetary and Binary Interpretations of Microlensing Central Perturbations under Severe Finite-Source Effect

description: In the current strategy of microlensing planet searches focusing on high-magnification events, wide and close binaries pose important sources of contamination that imitates planetary signals. For the purpose of finding systematic differences, we compare the patterns of central perturbations induced by a planet and a binary companion under severe finite-source effect. We find that the most prominent difference shows up in the morphology of the edge features with negative excess that appear at the edge of the circle with its center located at the caustic center and a radius equivalent to the source radius. It is found that the feature induced a binary companion forms a complete annulus, while the feature induced by a planet appears as several arc segments. This difference provides a useful diagnostic for immediate iscrimination of a planet-induced perturbation from that induced by a binary companion, where the absence of a well-developed dip in the residual from the single-lensing light curve at both or either of the moments of the caustic center's entrance into and exit from the source star surface indicates that the perturbation is produced by a planetary companion. We find that that this difference is basically caused by the difference between the shapes of the central caustics induced by the two different types of companions.

description: We have analyzed ACS/WFC and WFPC2 images from HST, as well as ground-based data to study the radial distribution of the double sub-giant branch (SGB) recently discovered in the Galactic globular cluster NGC 1851. We found that the SGB split can be followed all the way from the cluster center out to at least 8\arcmin from the center. Beyond this distance out to the tidal radius at $\sim 11.7$ arcmin, there are simply too few SGB stars to dentify the sequences. The number ratio of the bright SGB to the faint SGB stars shows no significant radial trend. Furthermore, we have found that the ratio of blue horizontal-branch (HB) stars plus RR Lyrae to the red HB stars also remains constant from the cluster center to the outer envelope.

Time-Resolved Upconversion of Entangled Photon Pairs

description: In the process of spontaneous parametric downconversion, photons from a pump field are converted to signal and idler photon pairs in a nonlinear crystal. The reversed process, or upconversion of these pairs back to single photons in a second crystal, is also possible. Here, we present experimental measurements of the upconversion rate with a controlled time delay introduced between the signal and idler photons. As a function of delay, this rate presents a full width at half maximum of 27.9 fs under our experimental conditions, and we further demonstrate that group delay dispersion of the photon pairs broadens this width. These observations are in close agreement with our calculations, thus demonstrating an ultrafast, nonclassical correlation between the signal and idler waves.
