description: 'Parameter design' is a procedure to identify settings of design variables that minimize variation in performance of a processing unit. However their application to the design of chemical processing units has not been widely reported. The objective of this study was to investigate the feasibility of using 'parameter design' methodologies to determine values of the design variables for a non-isothermal Continuous Stirred Tank Reactor which minimized the sensitivity of product quality to disturbances. The relative merits of each approach and the potential for application of 'parameter design' to chemical unit design are discussed. In summary, Response Surface Methodology associated with Monte Carlo simulations was found to be very efficient. Error Transmission Analysis did not perform well because of the inaccuracy of the first-order approximation adopted in the transmitted variation function. The use of the Taguchi Method was not always justified due to the universal logarithmic transformation, and the use of the marginal means. Sequential Elimination of Levels was found to be generally unreliable. (Abstract shortened by UMI.)

description: Background: Orally administered sucrose is effective and safe in reducing pain intensity during single, tissue-damaging procedures in neonates, and is commonly recommended in neonatal pain guidelines. However, there is wide variability in sucrose doses examined in research, and more than a 20-fold variation across neonatal care settings. The aim of this study was to determine the minimally effective dose of 24% sucrose for reducing pain in hospitalized neonates undergoing a single skin-breaking heel lance procedure. Methods: A total of 245 neonates from 4 Canadian tertiary neonatal intensive care units (NICUs), born between 24 and 42 weeks gestational age (GA), were prospectively randomized to receive one of three doses of 24% sucrose, plus non-nutritive sucking/pacifier, 2 min before a routine heel lance: 0.1 ml (Group 1; n = 81), 0.5 ml (Group 2; n = 81), or 1.0 ml (Group 3; n = 83). The primary outcome was pain intensity measured at 30 and 60 s following the heel lance, using the Premature Infant Pain Profile-Revised (PIPP-R). The secondary outcome was the incidence of adverse events. Analysis of covariance models, adjusting for GA and study site examined between group differences in pain intensity across intervention groups. Results: There was no difference in mean pain intensity PIPP-R scores between treatment groups at 30 s (P = .97) and 60 s (P = .93); however, pain was not fully eliminated during the heel lance procedure. There were 5 reported adverse events among 5/245 (2.0%) neonates, with no significant differences in the proportion of events by sucrose dose (P = .62). All events resolved spontaneously without medical intervention. Conclusions: The minimally effective dose of 24% sucrose required to treat pain associated with a single heel lance in neonates was 0.1 ml. Further evaluation regarding the sustained effectiveness of this dose in reducing pain intensity in neonates for repeated painful procedures is warranted.

description: Sedentary behavior is highly prevalent in office-based workplaces; however, few studies have assessed the attributes associated with this health risk factor in the workplace setting. This study aimed to identify the correlates of office workers' objectively-assessed total and prolonged (≥ 30 min bouts) workplace sitting time. Participants were 231 Australian office workers recruited from 14 sites of a single government employer in 2012–13. Potential socio-demographic, work-related, health-related and cognitive-social correlates were measured through a self-administered survey and anthropometric measurements. Associations with total and prolonged workplace sitting time (measured with the activPAL3) were tested using linear mixed models. Worksites varied significantly in total workplace sitting time (overall mean [SD]: 79% [10%] of work hours) and prolonged workplace sitting time (42% [19%]), after adjusting for socio-demographic and work-related characteristics. Organisational tenure of 3–5 years (compared to tenure > 5 years) was associated with more time spent in total and prolonged workplace sitting time, while having a BMI categorised as obese (compared to a healthy BMI) was associated with less time spent in total and prolonged workplace sitting time. Significant variations in sitting time were observed across different worksites of the same employer and the variation remained after adjusting for individual-level factors. Only BMI and organisational tenure were identified as correlates of total and prolonged workplace sitting time. Additional studies are needed to confirm the present findings across diverse organisations and occupations.

description: Background Maternal sensitive behavior depends on recognizing one’s own child’s affective states. The present study investigated distinct and overlapping neural responses of mothers to sad and happy facial expressions of their own child (in comparison to facial expressions of an unfamiliar child). Methods We used functional MRI to measure dissociable and overlapping activation patterns in 27 healthy mothers in response to happy, neutral and sad facial expressions of their own school-aged child and a gender- and age- matched unfamiliar child. To investigate differential activation to sad compared to happy faces of one’s own child, we used interaction contrasts. During the scan, mothers had to indicate the affect of the presented face. After scanning, they were asked to rate the perceived emotional arousal and valence levels for each face using a 7-point Likert-scale (adapted SAM version). Results While viewing their own child’s sad faces, mothers showed activation in the amygdala and anterior cingulate cortex whereas happy facial expressions of the own child elicited activation in the hippocampus. Conjoint activation in response to one’s own child happy and sad expressions was found in the insula and the superior temporal gyrus. Conclusions Maternal brain activations differed depending on the child’s affective state. Sad faces of the own child activated areas commonly associated with a threat detection network, whereas happy faces activated reward related brain areas. Overlapping activation was found in empathy related networks. These distinct neural activation patterns might facilitate sensitive maternal behavior.
Impacts of water residence time on lake thermal structure: implications for management and climate change
Creators: name: Olsson, Freya
Publisher: name: Lancaster University

description: Lakes provide globally important ecosystem services. However, the dual threats of eutrophication and climate change threaten lakes’ ability to provide these services. Water residence time (WRT), the ratio between lake volume and discharge, is important for lake functioning, affecting nutrient loading, time available for biogeochemical processes, and flushing of biota. WRT manipulations have been proposed as a novel management intervention to restore eutrophic lakes by inhibiting seasonal stratification and thereby preventing hypolimnetic anoxia and associated internal loading. However, the impact of WRT on lake thermal structure is not well understood, and the contribution of inflows to lake heat budgets are often overlooked. Changes to WRT are also relevant in a climate change context. River flow changes, driven by evaporation and precipitation changes, are projected for more than three-quarters of the landmass. This thesis uses long-term and high-frequency data from a small UK lake, alongside hydrodynamic modelling to examine the extent to which management and climate-induced WRT changes could affect lake thermal structure and subsequent impacts on lake function. Results reveal that annual WRT changes impact lake temperatures year-round, with the direction of change seasonal. Shorter WRT caused cooling in the summer and warming in the winter. Annual WRT reductions failed to inhibit stratification, only weakening stability, and hypolimnetic anoxia persisted. However, results showed that reductions in WRT were enhancing deep-water oxygenation and that strategic sub-seasonal management could potentially control internal loading. WRT changes during the summer stratified period were associated with short-term reductions in water column stability, increased vertical mixing, and replenishment of deep-water oxygen. Results also highlighted that in the northwest of England, river flow changes are likely to be exacerbating air temperature warming impacts on lakes. Failing to account for future WRT changes could be underestimating the impact of climate change, in a multitude of short-residence time lakes.

description: Dans le but d'elucider la dynamique de l'apprentissage de groupe, nous analysons la resolution de probleme en termes de strategies et d'accomplissement en situation. Les strategies sont observees au cours de la resolution d'un probleme creatif complexe et peu defini, et des notes de nature biographique sont prises sur le contexte d'implantation et d'experience de ces strategies. Nous proposons une definition originale des strategies de resolution de probleme. Les strategies sont definies comme un ensemble de choix reflexifs et regulateurs etablis en connexion avec le contexte de la tache et en coherence avec des buts sociaux. Ces choix sont operes dans chaque groupe d'apprentissage en accord avec un regulateur different: pair, stagiaire, ou expert. Ces regulateurs se preparent, interviennent en un discours pedagogique dont des extraits sont analyses, et reflechissent a voix haute apres l'action sur ses implications. L'objectif general de la recherche est de determiner par des moyens quantitatifs et qualitatifs quelles strategies d'apprentissage, lors de la resolution d'un probleme en groupe, sont reliees a la reussite de la tache et aux progres des eleves: (a) Determiner la relation entre l'organisation observee dans des groupes regules par une enseignante experte, une novice ou un pair, et la reussite d'une tache verbale complexe sur le plan des savoirs, des procedures, et de l'experience; (b) Decrire le traitement de l'information dans la resolution du probleme pose dans chaque groupe en indiquant le role des informations issues de l'environnement de la tache, des modeles de situation interiorises par les eleves, des dispositions et des buts sociaux-affectifs; (c) Interpreter les resultats en termes d'optimalisation de l'apprentissage en groupe. Le probleme analyse consiste a enregistrer, en groupe, un message original et creatif sur un repondeur telephonique (message sortant). Pendant l'experimentation, la regulation dans la resolution de probleme porte sur plusieurs episodes strategiques: ecouter ou lire les consignes, reflechir, planifier, explorer, appliquer et verifier. L'ensemble du processus d'apprentissage est influence par des situations particulieres: experience anterieure, implicite ou explicite, modeles de situation (maniere dont les enfants se representent ce qu'ils font), biographies individuelles et de groupe.

description: Glutamate receptors form complexes in the brain with auxiliary proteins, which control their activity during fast synaptic transmission through a seemingly bewildering array of effects. Here we devise a way to isolate the activation of complexes using polyamines, which enables us to show that transmembrane AMPA receptor regulatory proteins (TARPs) exert their effects principally on the channel opening reaction. A thermodynamic argument suggests that because TARPs promote channel opening, receptor activation promotes AMPAR-TARP complexes into a superactive state with high open probability. A simple model based on this idea predicts all known effects of TARPs on AMPA receptor function. This model also predicts unexpected phenomena including massive potentiation in the absence of desensitization and supramaximal recovery that we subsequently detected in electrophysiological recordings. This transient positive feedback mechanism has implications for information processing in the brain, because it should allow activity-dependent facilitation of excitatory synaptic transmission through a postsynaptic mechanism.
R-loops’ effect on chromosome stability and temporal regulation of DNA double-strand break processing in the C. elegans germline
Creators: name: Hicks, Tara Lynn
Publisher: name: University of Iowa
Year: 2026

description: DNA double strand breaks (DSBs) represent one of the most genotoxic and deleterious types of DNA damage. Their efficient and timely repair is essential and improperly repaired or unrepaired DSBs can directly lead to major genome catastrophe by way of chromosome rearrangements and cell death. Germ cell chromosomes endure programmed DSB induction catalyzed by the topoisomerase-like protein Spo11 during meiotic prophase I which are essential to the establishment of crossovers (COs) between homologous chromosomes that drive proper chromosome segregation during meiotic divisions. The significance of DSB lesions in germ nuclei, where aberrant DSB repair products can be passed to gametes, therefore mandates critical understanding of the processes which contribute to faithful DSB processing and resolution in this context. This thesis serves to further this understanding by investigating the temporal regulation of programmed DSB induction by SPO-11 and end processing in the context of adult Caenorhabditis elegans germlines. Our work uncovers that late DSBs are essential for CO formation and are preferentially processed by the exonucleases EXO-1 and DNA-2 in a redundant fashion. Further, DNA-2/EXO-1-mediated resection ensures completion of conservative DSB repair and discourages end joining to prevent error-prone repair outcomes. The work in this thesis also provides evidence of an intimate link between DSB repair in stem cells and in gametogenesis by way of RNase H-dependent R-loop resolution necessary to support checkpoint-mediated identification and elimination of damaged chromosomes. Additionally, de novo DNA-RNA hybrids in this thesis elucidate a novel population of SPO-11-dependent DNA-RNA hybrids, whose proper mediation requires germline RNase H activity to help drive CO interference. This research therefore provides several novel insights into DSB repair in both stem cells and developing oocytes and to CO fate determination in metazoan prophase I.

description: We study the stellar-to-halo mass relation of central galaxies in the range 9.7 < log10(M*/h⁻² M⊙) < 11.7 and z < 0.4, obtained from a combined analysis of the Kilo Degree Survey (KiDS) and the Galaxy And Mass Assembly (GAMA) survey. We use ~100 deg² of KiDS data to study the lensing signal around galaxies for which spectroscopic redshifts and stellar masses were determined by GAMA. We show that lensing alone results in poor constraints on the stellar-to-halo mass relation due to a degeneracy between the satellite fraction and the halo mass, which is lifted when we simultaneously fit the stellar mass function. At M* > 5 × 10¹⁰ h⁻² M⊙, the stellar mass increases with halo mass as ~M0.25. The ratio of dark matter to stellar mass has a minimum at a halo mass of 8 × 10¹¹ h⁻¹ M⊙ with a value of M/M* = 56-10⁺¹⁶ [h]. We also use the GAMA group catalogue to select centrals and satellites in groups with five or more members, which trace regions in space where the local matter density is higher than average, and determine for the first time the stellar-to-halo mass relation in these denser environments. We find no significant differences compared to the relation from the full sample, which suggests that the stellar-to-halo mass relation does not vary strongly with local density. Furthermore, we find that the stellar-to-halo mass relation of central galaxies can also be obtained by modelling the lensing signal and stellar mass function of satellite galaxies only, which shows that the assumptions to model the satellite contribution in the halo model do not significantly bias the stellar-to-halo mass relation. Finally, we show that the combination of weak lensing with the stellar mass function can be used to test the purity of group catalogues.

description: Background Galectin-7 (Gal-7) is negatively regulated in cervical cancer, and appears to be a link between the apoptotic response triggered by cancer and the anti-tumoral activity of the immune system. Our understanding of how cervical cancer cells and their molecular networks adapt in response to the expression of Gal-7 remains limited. Methods Meta-analysis of Gal-7 expression was conducted in three cervical cancer cohort studies and TCGA. In silico prediction and bisulfite sequencing were performed to inquire epigenetic alterations. To study the effect of Gal-7 on cervical cancer, we ectopically re-expressed it in the HeLa and SiHa cervical cancer cell lines, and analyzed their transcriptome and SILAC-based proteome. We also examined the tumor and microenvironment host cell transcriptomes after xenotransplantation into immunocompromised mice. Differences between samples were assessed with the Kruskall-Wallis, Dunn’s Multiple Comparison and T tests. Kaplan–Meier and log- rank tests were used to determine overall survival. Results Gal-7 was constantly downregulated in our meta-analysis (p

description: Additive manufacturing (AM) technologies have proven to be a powerful tool to create ceramics with complex geometries, which are difficult to achieve using traditional machining processes due to their brittleness. For existing AM processes of ceramics, the use of organic binders leads to problems of structural defects, accumulated stress and compromised material properties in the final parts. In this work, a new AM method for ceramics called Hydrothermal-assisted jet fusion (HJF) is proposed, which is capable of fabricating ceramic 3D structures without the need for organic binders. The HJF process selectively deposits a water-based solution into a ceramic powder bed in a layer-by-layer manner and fuses particles together through a hydrothermal mechanism. Since no organic binder is used, it can produce ceramic parts with less energy consumed for binder removal and has the potential to reach the material's theoretical properties such as full density and exceptional mechanical strength. To improve the printing fidelity of HJF process, droplet diffusion behavior in the powder bed under the influence of powder bed’s packing density and compaction pressure was simulated and verified by experiments. Meanwhile, microstructure and physical properties of the printing parts in HJF process were studied under the effect of process parameters such as compaction pressure, ink concentration, etc. Besides, interparticle mass transfer in HJF process was also simulated to understand the fusion mechanism. Finally, HJF process was utilized in the application of antennas, which proves its capability for the direct integration of ceramics with dissimilar materials such as metals and polymers.

description: Fluxgate magnetometers are important tools for space plasma studies, but these instruments are sensitive to temperature changes in their calibrations due to the wide temperature range that be experienced during orbit. It is critical to characterize their calibration over temperature changes prior to flight. However, building a facility that can maintain a stable magnetic and thermal environment is difficult due to temperature sensitivity of magnetic shielding and building materials. A new calibration facility is desired to span the broad range of positive and negative temperatures experienced in space missions, while providing accurate control for test instruments and producing a three-axis vector magnetic field that can be used for calibration.
description: This temperature testing device was built to accurately calibrate the magnetometers with temperature control for both heating and cooling in the range of -80 to +80 °C. Current calibration methods are limited to an improvised cooling-only system constructed with dry ice. There is a limited number of comparable apparatuses available worldwide, and unlike these similar apparatuses the new facility introduces the additional ability to obtain orthogonality measurements of the relative angles between the three components measured by the magnetometer. The apparatus produces a known and highly stable three-axis magnetic field that is isolated from time-varying external fields that can confound the calibration. A three-layer MuMETAL shield provides this protection from time-varying external fields. A custom-sized Helmholtz coil was designed and built to fit within the shield and generate the necessary magnetic field to which to calibrate the magnetometer. The instrument is housed inside a dewar into which nitrogen is supplied. This insulates the Helmholtz coil and shield from changes in performance that occur when exposed to temperature fluxes. A thermal conditioning unit iv supplies controlled flows of liquid and gaseous nitrogen to the dewar, creating a controlled thermal environment. Additional insulation prevents condensation. The design of the facility was verified using heat transfer analysis and ANSYS simulations. Structural analysis on the Helmholtz coil was performed using CREO Simulate. The multi-layered build allows for the complete three-axis calibration of magnetometers up to 5.5 inches in width within a temperature range of -80 to +80 °C. The facility is currently being built and commissioned for potential use for the TRACERS satellite mission.

description: Virtual environments (VEs) are interactive computer simulations that immerse users in an alternate reality. Multi-user VE applications simulate the experience of real-time interaction among multiple users in a shared three-dimensional (3D) virtual world. The Internet has a growing importance as a communication medium for presenting multi-user VEs and interaction among distributed VEs. In this thesis, we identify the requirements for highly interactive multi-user VEs and limitations of collaboration over the Internet. We focus on the design, implementation, and evaluation of network communication infrastructures for multi-user virtual environments, also exploiting the multicast and quality of service (QoS) support introduced with IPv6, the next generation Internet protocol. We propose an architecture, VESIR-6, that combines the 3-D navigational and interactive capabilities of virtual worlds with the communication capability of the next generation IPv6 protocol to bring people together in one virtual world, regardless of their physical locations, in a platform-independent manner. The goal of the project is to get all the parties together in one virtual world, allowing them to see each other, to interact with each other, and to affect that common world in a secure and high-quality network infrastructure over the Internet.

description: The rapid growth of the Internet has brought us endless choice, but it is also difficult to find items according to personal interests. Nowadays, a website is more like an island. In order to find useful information, you need to jump from one page to another page through the links. A web based system for managing context would give users the ability to manage personal context, collect interesting links, and attach notes, so that only one or two clicks would be required to reach the useful information. Such context is valuable, so it would also be useful if it could be shared with others. We survey the technology available to create the Enriched Web Services Architecture in order to give a rich user experience in a browser application. We also survey current approaches and issues in managing and sharing context. Based on both surveys we propose architecture for context management and sharing. An example system, for Management and Sharing of Context (MSC) is built as a case study and evaluated. The example system helps people to collect links and articles in order to manage their context and share context with others.

The horizon of political liberalism: Citizenship, culture and the limits of Rawlsian public reason.
Creators: name: Peddle, David.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Philosophy.

description: The thesis developed in this essay is that public political debate must accommodate the moral, religious and cultural dimensions of citizenship. Commitment to shared public deliberation and participation can be developed only if citizens are drawn into political engagement with their various embedded identities intact; their personal integrity can be sustained only if they can bring to bear all the moral resources with which they are graced. Moreover, citizens' cultural identities, because they are a source of a deep sense of belonging, will pose an obstacle to common political life unless a common political culture can transform (and be transformed by) their culture of origin. "Political" culture must be seen as arising from the historical identity formed from the various differing roots of the background culture. "Non-political" culture is likewise transformed by the political realm. The locus of basic political issues, then, cannot be described simply as "political"; rather, it must be seen as "cultural-political", "moral-political" or "religious-political", each realm determining the configuration of the other. This then is the primary meaning of the term "horizon" in this essay's title: the comprehensive and cultural commitments of citizens must play an important role in defining the nature and limits of public political reason in any determinate account of liberal democracy. Through consideration of the instructive debate generated by John Rawls's of "political" conception of justice and responses to this conception by Michael Sandel and Will Kymlicka, this essay attempts to develop a more inclusive conception of public reason. I am concerned to broaden the scope of public reason in three ways: (1) to further include citizens' comprehensive views in public debate; (2) to ensure recognition of the importance of the history of democratic institutions within the conception of the political and; (3) to extend the defense of group-differentiated rights to include exemptions for non-liberal religious groups. The concept of public reason and political participation developed in this essay attempts to show how the differences between liberalism and republicanism may be diminished. It presents a liberalism enriched by a more inclusive public reason and by a richer understanding of the historical nature the public culture. Also it defends a pluralist republicanism which, tainted by neither exclusion nor coercion, represents a viable alternative to liberal neutrality.

description: We look for correlated changes in stellar mass and star formation rate (SFR) along filaments in the cosmic web by examining the stellar masses and UV-derived SFRs of 1799 ungrouped and unpaired spiral galaxies that reside in filaments. We devise multiple distance metrics to characterize the complex geometry of filaments, and find that galaxies closer to the cylindrical centre of a filament have higher stellar masses than their counterparts near the periphery of filaments, on the edges of voids. In addition, these peripheral spiral galaxies have higher SFRs at a given mass. Complementing our sample of filament spiral galaxies with spiral galaxies in tendrils and voids, we find that the average SFR of these objects in different large-scale environments are similar to each other with the primary discriminant in SFR being stellar mass, in line with previous works. However, the distributions of SFRs are found to vary with large-scale environment. Our results thus suggest a model in which in addition to stellar mass as the primary discriminant, the large-scale environment is imprinted in the SFR as a secondorder effect. Furthermore, our detailed results for filament galaxies suggest a model in which gas accretion from voids on to filaments is primarily in an orthogonal direction. Overall, we find our results to be in line with theoretical expectations of the thermodynamic properties of the intergalactic medium in different large-scale environments.

description: Biochemical reactors (BCRs) based on the stimulation of sulphate-reducing microorganisms (SRM) are emerging semi-passive remediation technologies for treatment of mine-influenced water. Their successful removal of metals and sulphate has been proven at the pilot-scale, but little is known about the types of SRM that grow in these systems and whether they are diverse or restricted to particular phylogenetic or taxonomic groups. A phylogenetic study of four established pilot-scale BCRs on three different mine sites compared the diversity of SRM growing in them. The mine sites were geographically distant from each other, nevertheless the BCRs selected for similar SRM types. Clostridia SRM related to Desulfosporosinus spp. known to be tolerant to high concentrations of copper were members of the core microbial community. Members of the SRM family Desulfobacteraceae were dominant, particularly those related to Desulfatirhabdium butyrativorans. Methanogens were dominant archaea and possibly were present at higher relative abundances than SRM in some BCRs. Both hydrogenotrophic and acetoclastic types were present. There were no strong negative or positive co-occurrence correlations of methanogen and SRM taxa. Knowing which SRM inhabit successfully operating BCRs allows practitioners to target these phylogenetic groups when selecting inoculum for future operations.

description: The use of multiple modalities (e.g., face and fingerprint) or multiple algorithms (e.g., three face comparators) has shown to improve the recognition accuracy of an operational biometric system. Over time a biometric system may evolve to add new modalities, retire old modalities, or be merged with other biometric systems. This can lead to scenarios where there are missing scores corresponding to the input probe set. Previous work on this topic has focused on either the verification or identification tasks, but not both. Further, the proportion of missing data considered has been less than 50%. In this work, we study the impact of missing score data for both the verification and identification tasks. We show that the application of various score imputation methods along with simple sum fusion can improve recognition accuracy, even when the proportion of missing scores increases to 90%. Experiments show that fusion after score imputation outperforms fusion with no imputation. Specifically, iterative imputation with K nearest neighbors consistently surpasses other imputation methods in both the verification and identification tasks, regardless of the amount of scores missing, and provides imputed values that are consistent with the ground truth complete dataset.

description: The Wernher collection of very important 15-16th century Limoges enamels is on exhibition at Rangers House. From previous research it is known how vulnerable these enamels are. As they are very sensitive to changes in the environment a suitable monitoring device for assessing instant damage was identified. Acoustic emission is a technique that has been widely used in engineering but has been applied in only in a few cases in conservation. The research project had two different strands: the first was determining the suitability of acoustic emission for detecting micro-cracks in Limoges enamels. Previous to applying the technique on the originals, enamel samples were used in flexure tests and exposed to variations of temperature to assess their response to stress induced deterioration. The temperature and RH distribution in two display cases were measured with data loggers at different points to assess the thermal loading. The second strand consisted of monitoring the showcases with diffusion tubes to assess internal formaldehyde, acetic and formic acids concentrations. High concentrations would cause corrosion of the enamel copper plates. Acoustic emission has proven to be a promising method for determining which parameters play an important role in the deterioration of the enamels in situ. It could be shown that rising temperatures in a showcase do appear to be causing damage to a Limoges enamel.
Ellen White and Miki Nakayama: A comparative study of mystical experience.

description: Through comparison between mystical experiences of Ellen White, one of the originators of the Seventh-day Adventist Church, and Miki Nakayama, foundress of the Tenrikyo sect, this study intends to (1) describe some of the similarities and differences seen in mystical experiences drawn from different contexts, and (2) analyze and explain the factors responsible for these similarities and differences. Mystical experience has at least three main aspects--natural, cultural, and personal. The first is the element that is very closely linked with human nature; the second refers to the side that is controlled by cultural tradition; the last signifies the totality of the mystic's personality and life history. Broadly speaking, similarities emerge in the natural phase of mystical experience; differences characterize the personal aspect; in the cultural aspect, however, both differences and similarities can be observed. That is to say, the former predominates when the experiences are compared through the prism of different cultures, whereas the latter is, as a rule, found within the same cultural environment. This study will explore the above theses by means of a comparison of the mystical experiences of White and Nakayama.

description: Recent developments in quantum photonics have initiated the process of bringing photonic-quantumbased systems out-of-the-lab and into real-world applications. As an example, devices to enable the exchange of a cryptographic key secured by the laws of quantum mechanics are already commercially available. In order to further boost this process, the next step is to transfer the results achieved by means of bulky and expensive setups into miniaturized and affordable devices. Integrated quantum photonics is exactly addressing this issue. In this paper, we briefly review the most recent advancements in the generation of quantum states of light on-chip. In particular, we focus on optical microcavities, as they can offer a solution to the problem of low efficiency that is characteristic of the materials typically used in integrated platforms. In addition, we show that specifically designed microcavities can also offer further advantages, such as compatibility with telecom standards (for exploiting existing fibre networks) and quantum memories (necessary to extend the communication distance), as well as giving a longitudinal multimode character for larger information transfer and processing. This last property (i.e., the increased dimensionality of the photon quantum state) is achieved through the ability to generate multiple photon pairs on a frequency comb, corresponding to the microcavity resonances. Further achievements include the possibility of fully exploiting the polarization degree of freedom, even for integrated devices. These results pave the way for the generation of integrated quantum frequency combs that, in turn, may find important applications toward the realization of a compact quantum-computing platform.

description: The increasing availability of highly detailed three-dimensional remotely-sensed data depicting forests, including airborne laser scanning (ALS) and digital aerial photogrammetric (DAP) approaches, provides a means for improving stand dynamics information. The availability of data from ALS and DAP has stimulated attempts to link these datasets with conventional forestry growth and yield models. In this study, we demonstrated an approach whereby two three-dimensional point cloud datasets (one from ALS and one from DAP), acquired over the same forest stands, at two points in time (circa 2008 and 2015), were used to derive forest inventory information. The area-based approach (ABA) was used to predict top height (H), basal area (BA), total volume (V), and stem density (N) for Time 1 and Time 2 (T1, T2). We assigned individual yield curves to 20 × 20 m grid cells for two scenarios. The first scenario used T1 estimates only (approach 1, single date), while the second scenario combined T1 and T2 estimates (approach 2, multi-date). Yield curves were matched by comparing the predicted cell-level attributes with a yield curve template database generated using an existing growth simulator. Results indicated that the yield curves using the multi-date data of approach 2 were matched with slightly higher accuracy; however, projections derived using approach 1 and 2 were not significantly different. The accuracy of curve matching was dependent on the ABA prediction error. The relative root mean squared error of curve matching in approach 2 for H, BA, V, and N, was 18.4, 11.5, 25.6, and 27.53% for observed (plot) data, and 13.2, 44.6, 50.4 and 112.3% for predicted data, respectively. The approach presented in this study provides additional detail on sub-stand level growth projections that enhances the information available to inform long-term, sustainable forest planning and management.

description: Nanolasers hold promise for applications including integrated photonics, on-chip optical interconnects and optical sensing. Key to the realization of current cavity designs is the use of nanomaterials combining high gain with high radiative efficiency. Until now, efforts to enhance the performance of semiconductor nanomaterials have focused on reducing the rate of non-radiative recombination through improvements to material quality and complex passivation schemes. Here we employ controlled impurity doping to increase the rate of radiative recombination. This unique approach enables us to improve the radiative efficiency of unpassivated GaAs nanowires by a factor of several hundred times while also increasing differential gain and reducing the transparency carrier density. In this way, we demonstrate lasing from a nanomaterial that combines high radiative efficiency with a picosecond carrier lifetime ready for high speed applications.
