Temnothorax misomoschus

description: misomoschus group overview This group is monotypic, with the nominal Temnothorax misomoschus sp. nov. being the only member. With its depressed propodeum, strongly curved propodeal spines, and nearly complete lack of standing setae, this species is distinctive in the salvini clade, not to mention the genus as a whole. Collected from only a couple of geographically disparate collections (southern Texas and Nicaragua; Fig. 120G), this species apparently has a large range, but we still know little about its biology. It is sister to the goniops group (Prebus, in prep.).

description: Unfälle mit Personenschäden haben auf Landstraßen in der Dunkelheit einen überproportionalen Anteil. Das untersuchte System möchte einen Beitrag dazu leisten, dass Autofahrer Fußgänger früher wahrnehmen können. Mittels Blickbewegungsanalysen wurden unterschiedlich gestaltete Fußgängermarkierungen eines Night-Vision-Systems in einem Kraftfahrzeug mit Head-up-Display (HUD) hinsichtlich ihrer ergonomischen Eignung und ihres ergonomischen Nutzens untersucht. Es wurden alle Systeme im Feld (öffentlicher Straßenverkehr) sowie kontrollierten Feld (Testgelände) miteinander verglichen. Dabei konnten abhängig von der Untersuchungsumgebung und dem Fahrauftrag unterschiedliche Ergebnisse bezüglich der Zeitpunkte der Wahrnehmung der Fußgänger durch die Fahrer festgestellt werden. Insgesamt zeigen die Ergebnisse, dass mit Hilfe von Nachtsichtsystemen Personen bei Dunkelheit früher wahrgenommen werden können. Eine zusätzliche Markierung von Fußgängern verbessert die Wahrnehmung des Fahrers deutlich.

description: In this chapter, we show why parallel MATLAB is useful, provide a comparison of the different parallel MATLAB choices, and describe a number of applications in Signal and Image Processing: Audio Signal Processing, Synthetic Aperture Radar (SAR) Processing and Superconducting Quantum Interference Filters (SQIFs). Each of these applications have been parallelized using different methods (Task parallel and Data parallel techniques). The applications presented may be considered representative of type of problems faced by signal and image processing researchers. This chapter will also strive to serve as a guide to new signal and image processing parallel programmers, by suggesting a parallelization strategy that can be employed when developing a general parallel algorithm. The objective of this chapter is to help signal and image processing algorithm developers understand the advantages of using parallel MATLAB to tackle larger problems while staying within the powerful environment of MATLAB.

description: In the framework of the functional renormalization group method it is shown that the phase structure of the 2-dimensional sine-Gordon model possesses a nontrivial UV fixed point which makes the model asymptotically safe. The fixed point exhibits strong singularity similarly to the scaling found in the vicinity of the infrared fixed point. The singularity signals the upper energy-scale limit to the validity of the model. We argue that the sine-Gordon model with a momentum-dependent wavefunction renormalization is in a dual connection with the massive sine-Gordon model.

description: We present a study of optically selected dual AGN with projected separations of 3--97~kpc. Using multi-wavelength (MWL) information (optical, X-rays, mid-IR), we characterized the intrinsic nuclear properties of this sample and compared them with those of isolated systems. Among the 124 X-ray detected AGN candidates, 52 appear in pairs and 72 as single X-ray sources. Through MWL analysis, we confirmed the presence of the AGN in a fraction >80\% of the detected targets in pairs (42 over 52). X-ray spectral analysis confirms the trend of increasing AGN luminosity with decreasing separation, suggesting that mergers may have contributed in triggering more luminous AGN. Through X/mid-IR ratio $vs$ X-ray colors, we estimated a fraction of Compton-thin AGN (with 10$^{22}$ cm$^{-2}$ $<$ N$_{\rm H} <$10$^{24}$ cm$^{-2}$) of about 80\%, while about 16\% are Compton thick (CT, with N$_{\rm H}>$10$^{24}$ cm$^{-2}$) sources. These fractions of obscured sources are larger than those found in samples of isolated AGN, confirming that pairs of AGN show higher obscuration. This trend is further confirmed by comparing the de-reddened [O\ III] emission with the observed X-ray luminosity. However, the derived fraction of Compton-thick sources in this sample at early stage of merging is lower than reported for late-merging dual-AGN samples. Comparing N$_{\rm H}$ from X-rays with that derived from E(B-V) from Narrow Line Regions, we find that the absorbing material is likely associated with the torus or the Broad Line Regions. We also explored the X-ray detection efficiency of dual-AGN candidates, finding that, when observed properly (at on-axis positions and with long exposures), X-ray data represent a powerful way to confirm and investigate dual-AGN systems.

description: We establish stability and characteristics of two-dimensional (2D) vortex ring-shaped quantum droplets (QDs) formed by binary Bose-Einstein condensates (BECs). The system is modeled by the Gross-Pitaevskii (GP) equation with the cubic term multiplied by a logarithmic factor (as produced by the Lee-Huang-Yang correction to the mean-field theory) and a potential which is a periodic function of the radial coordinate. Narrow vortex rings with high values of the topological charge, trapped in particular circular troughs of the radial potential, are produced. These results suggest an experimentally relevant method for the creation of vortical QDs (thus far, only zero-vorticity ones have been reported). The 2D GP equation for the narrow rings is approximately reduced to the 1D form, which makes it possible to study the modulational stability of the rings against azimuthal perturbations. Full stability areas are delineated for these modes. The trapping capacity of the circular troughs is identified for the vortex rings with different winding numbers (WNs). Stable compound states in the form of mutually nested concentric multiple rings are constructed too, including ones with opposite signs of the WNs. Other robust compound states combine a modulationally stable narrow ring in one circular potential trough and an azimuthal soliton performing orbital motion in an adjacent one. The results may be used to design a device employing coexisting ring-shaped modes with different WNs for data storage.

Temnothorax pastinifer

description: pastinifer group overview With five species (one described as new here), the pastinifer group spans the low elevations of the Bahamas and Cuba (Fig. 121). This group is likely composed of littoral specialists, as it has only been collected from low-lying habitats near the sea. Most nest collections have been taken from wood or woody fruits lying on the ground. These distinctive species have extremely arched mesosomata, broad postpetioles, and incrassate femora, and so are prime examples of the Macromischa syndrome. Members of the pastinifer group may be confused with Temnothorax subditivus, members of the pulchellus group, or morphologically convergent members of the sallei clade. Because of multiple character overlaps between these groups, the keys above and the ‘similar species’ sections below should be used to determine species group membership. The nominal T. pastinifer and T. rutabulafer sp. nov. have historically been conflated as a single species, probably due to a mixed pin prepared by W.M. Mann.

Spectroscopic determination of C, N, and O abundances of solar-analog stars based on the lines of hydride molecules

description: Photospheric C, N, and O abundances of 118 solar-analog stars were determined by applying the synthetic-fitting analysis to their spectra in the blue or near-UV region comprising lines of CH, NH, and OH molecules, with an aim of clarifying the behaviors of these abundances in comparison with [Fe/H]. It turned out that, in the range of -0.6<[Fe/H]<+0.3, [C/Fe] shows a marginally increasing tendency with decreasing [Fe/H] with a slight upturn around [Fe/H]~0, [N/Fe] tends to somewhat decrease towards lower [Fe/H], and [O/Fe] systematically increases (and thus [C/O] decreases) with a decrease in [Fe/H]. While these results are qualitatively consistent with previous determinations mostly based on atomic lines, the distribution centers of these [C/Fe], [N/Fe], and [O/Fe] at the near-solar metallicity are slightly negative by several hundredths dex, which is interpreted as due to unusual solar abundances possibly related to the planetary formation of our solar system. However, clear anomalies are not observed in the [C,N,O/Fe] ratios of planet-host stars. Three out of four very Be-deficient stars were found to show anomalous [C/Fe] or [N/Fe] which may be due to mass transfer from the evolved companion, though its relation to Be depletion mechanism is still unclear.

description: Context: Herschel observations suggest that the H$_2$O distribution in outflows from low-mass stars resembles the H$_2$ emission. It is still unclear which of the different excitation components that characterise the mid- and near-IR H$_2$ distribution is associated with H$_2$O. Aim: The aim is to spectrally resolve the different excitation components observed in the H$_2$ emission. This will allow us to identify the H$_2$ counterpart associated with H$_2$O and finally derive directly an H$_2$O abundance estimate with respect to H$_2$. Methods: We present new high spectral resolution observations of H$_2$ 0-0 S(4), 0-0 S(9), and 1-0 S(1) towards HH 54, a bright nearby shock region in the southern sky. In addition, new Herschel-HIFI H$_2$O (2$_{12}$$-$1$_{01}$) observations at 1670~GHz are presented. Results: Our observations show for the first time a clear separation in velocity of the different H$_2$ lines: the 0-0 S(4) line at the lowest excitation peaks at $-$7~km~s$^{-1}$, while the more excited 0-0 S(9) and 1-0 S(1) lines peak at $-$15~km~s$^{-1}$. H$_2$O and high-$J$ CO appear to be associated with the H$_2$ 0-0 S(4) emission, which traces a gas component with a temperature of 700$-$1000 K. The H$_2$O abundance with respect to H$_2$ 0-0 S(4) is estimated to be $X$(H$_2$O)$

Midlife cardiovascular indicators of cerebral white matter health and cognitive function

Subjects: Arterial stiffness

description: Recent evidence suggests that modifiable cardiovascular risk factors additionally play a causal role in the development of dementia and cognitive dysfunction. Currently, no cure for dementia exists making identification of early relationships in dementia pathophysiology critical for the purpose of primary prevention or remediation. As approximately 70% of adults in the United States are clinically overweight, the aim of Study 1 was to determine the anthropometric measures most strongly associated with early white matter disease and cognitive function at midlife. In this cross-sectional investigation of 126 middle-aged adults, waist circumference, body fat percentage, and visceral adiposity all significantly predicted white matter hyperintensities, indicating that midlife abdominal obesity is associated with the early development of white mater disease. Midlife visceral adiposity is also associated with increased arterial stiffening. The aim of Study 2 was to determine if subclinical carotid artery stiffening is associated with lower cerebral white matter integrity at midlife in a priori regions of interest susceptible to vascular and cognitive aging. This study employed diffusion tensor imaging to gauge cerebral white matter integrity. In a middle-aged cohort of 143 adults, we determined that arterial stiffening was associated with reduced integrity of multiple white matter regions independent of age, sex, and waist circumference. Arterial stiffness indirectly affected processing speed. These data suggest that arterial stiffening may negatively affect CWMI prior to clinically overt cognitive decline. Individuals with metabolic syndrome are at increased risk of arterial stiffening and dementia. The purpose of Study 3 was to determine the role of physical activity on mitigating the adverse influence of metabolic syndrome on arterial stiffness and cerebral white matter integrity. In this cross-sectional investigation of 66 middle-aged adults, individuals with MetS who were physically active demonstrated lower arterial stiffness and more favorable CWM integrity than their sedentary peers, indicating that PA may be effective in mitigating the adverse effects of MetS on the vasculature and brain at midlife. Taken together, these findings indicate that cardiometabolic risk factors negatively affect the vasculature, cerebral white matter health, and cognitive function at middle-age
Stabilization of the astropause by periodic fluctuations of the stellar wind

description: The main goal of the paper is to explore why observations of many astrospheres (or circumstellar bubbles) show quite stable and smooth structures of astropauses - the tangential discontinuities separating the stellar and interstellar winds, - while both theory and numerical simulations suggest that tangential discontinuities are unstable due to well known Kelvin-Helmholtz (K-H) instability. It was recognized before that magnetic fields may stabilize the astropauses. In this paper, we explore another mechanism to reduce the K-H instability of the astropauses. This mechanism is a periodic change of the stellar wind dynamic pressure. Fluctuations of the stellar wind parameters are quite expected. For example, the Sun has an 11-year cycle of global activity although there are also shorter periods of the solar wind fluctuations. We performed the parametric numerical study and demonstrate that the development of the K-H instability depends on the dimensionless parameter $χ$ which is the ratio of the stellar wind terminal speed and interstellar flow speed. The larger the parameter $χ$, the larger the fluctuations caused by the K-H instability. It has been shown that the K-H instability is convective which agrees with the previous linear analysis. The stabilization of the astropause by the periodic fluctuations in the stellar wind lead is demonstrated. It is shown that for the solar wind the most effective stabilization occurs when the period of stellar parameter change is about 1-4 years. For the eleven year solar cycle, the stabilization effect is weaker.

Multidimensional integration through Markovian sampling under steered function morphing: a physical guise from statistical mechanics
Creators: name: Zerbetto, Mirco

Year: 2014
Subjects: subject: Applications (stat.AP)

description: We present a computational strategy for the evaluation of multidimensional integrals on hyper-rectangles based on Markovian stochastic exploration of the integration domain while the integrand is being morphed by starting from an initial appropriate profile. Thanks to an abstract reformulation of Jarzynski's equality applied in stochastic thermodynamics to evaluate the free-energy profiles along selected reaction coordinates via non-equilibrium transformations, it is possible to cast the original integral into the exponential average of the distribution of the pseudo-work (that we may term "computational work") involved in doing the function morphing, which is straightforwardly solved. Several tests illustrate the basic implementation of the idea, and show its performance in terms of computational time, accuracy and precision. The formulation for integrand functions with zeros and possible sign changes is also presented. It will be stressed that our usage of Jarzynski's equality shares similarities with a practice already known in statistics as Annealed Importance Sampling (AIS), when applied to computation of the normalizing constants of distributions. In a sense, here we dress the AIS with its "physical" counterpart borrowed from statistical mechanics.

Reputational crisis

description: This thesis uses attribution theory and situational crisis communication theory (SCCT) to examine the association between CEO’s personal risk and corporate reputational risks on the social media platforms by analyzing the case of JD.com. The thesis shows that JD.com’ situation partially reflected the research questions proposed based on attribution theory and SCCT. Social media users tended to attribute the fault of CEO’s sexual misconduct to JD.com after the crisis happened, which eventually impacted on the company’s reputation. Meanwhile, based on the SCCT theory, the thesis found no recovery trend was observed since the company did not react to the online discussion. However, this thesis failed to conclude that JD.com’s pre-crisis online discussion had different patterns than the post-crisis discussion, and the comparison between JD.com and its competitor also could not support the hypothesis that JD.com suffered reputational crisis caused by its CEO's personal risk

description: Fast radio bursts (FRBs) are bright millisecond radio bursts at cosmological distances. Only a small fraction of FRBs apparently repeat. Polarization, a fundamental property of electromagnetic signals, often carries critical information about the radiation processes, the environment, and the intervening medium of FRBs. Here we report circular polarization detections of two active repeating FRBs, namely FRBs 20121102A and 20190520B, with the Five-hundred-meter Aperture Spherical radio Telescope. We detect circular polarization in both active repeating FRBs, which increases the number of repeating FRBs with circular polarization to three. In one of the bursts of FRB 20121102A, we detect 64% degree of circular polarization. The observed circular polarization is unlikely induced by multipath propagation. Our observations favor circular polarization induced by Faraday conversion or radiation mechanism intrinsic to the FRB source. The conditions to generate circular polarization have to be rare in either case.

Charter schools

description: The purpose of this study was to examine legislators’ perceptions of the quality of education in public and charter schools, and the level of influence or impact their perceptions and experiences have on educational public policies in the Texas legislature. The research questions were: 1) To what extent do life experiences, meanings, background, participation, relationships, activities, and political ideology of state legislators formulate perceptions leading to educational public policy? 2) How do a legislator’s perceptions and district demographics influence support or opposition to legislation on public and charter schools? A qualitative methodology and Stone’s urban regime theory (2015) were applied in this study. The data collection consisted of structured interviews with ten Texas state legislators from both urban and rural districts, and included members from both major political parties. The interview questions queried about perceptions and life experiences regarding public and charter schools. The data were coded and analyzed utilizing codes presented by Bogdan and Biklen (1992) and Lofland (1971), and ranked based on frequency in the participating legislator’s responses. The findings for Research Question 1 analyzed the major themes of life experiences, meanings, background, participation, relationships, activities, and political ideology of state legislators and their influence on state legislators’ perceptions of public and charter schools. The theme with the highest influence was life experiences, while the second strongest theme influencing their perceptions was background. Political Ideology was the theme least influencing a legislator’s perceptions of public and charter school educational public policies. The findings for Research Question 2 identified the level of influence of two themes, settings and perceptions, on a legislator’s support of public and charter school legislative bills. The theme of settings had the highest influence for support or opposition to the legislative bills HB 21, SB 1882, and the HB 21 Amendment. The second strongest theme influencing a legislator’s support or opposition to public and charter school bills was perceptions. This study provided an insight into what impacts or influences a legislator’s decisions on educational public policy. This study was unique in that it provided insight into the thought process of public officials, with questions focusing on personal background and life experiences.

Technically, we study bifurcation in the presence of essential spectrum. We contribute a simple and direct functional analytic method and determine bifurcation coefficients explicitly. Our approach uses exponential weights to recover Fredholm properties and spectral flow ideas to compute Fredholm indices. Simple mass conservation helps compensate for negative indices. We also construct an explicit, prototypical example, prove the existence of a bifurcating front, and determine the direction of bifurcation.

description: Using theory and simulations, we carried out a first systematic characterization of DNA unzipping via nanopore translocation. Starting from partially unzipped states, we found three dynamical regimes depending on the applied force, f: (i) heterogeneous DNA retraction and rezipping (f < 17pN), (ii) normal (17pN < f < 60pN) and (iii) anomalous (f > 60pN) drift-diffusive behavior. We show that the normal drift-diffusion regime can be effectively modelled as a one-dimensional stochastic process in a tilted periodic potential. We use the theory of stochastic processes to recover the potential from nonequilibrium unzipping trajectories and show that it corresponds to the free-energy landscape for single base-pairs unzipping. Applying this general approach to other single-molecule systems with periodic potentials ought to yield detailed free-energy landscapes from out-of-equilibrium trajectories.

title: Deep learning for lung cancer analysis
Creators: name: Anderson, Owen
Publisher: name: University of Glasgow

description: This thesis describes the development and evaluation of two novel deep learning applications that tackle two cancers that affect the lungs. The first, lung cancer, is the largest cause of cancer-related deaths in the United Kingdom. It accounts for more than 1 in 5 cancer deaths; around 35,000 people every year. Lung cancer is curable providing it is detected very early. Computed tomography (CT) X-ray imaging has been shown to be effective for screening. However, the resulting 3D medical images are laborious for humans to read, and widespread adoption would put a huge strain on already stretched radiology departments. I developed a novel deep learning based approach for the automatic detection of lung nodules, potential early lung cancer, that has potential to reduce human workloads. It was evaluated on two independent datasets, and achieves performance competitive with published state-of-the-art tools, with average sensitivity of 84% to 92% at 8 false positives per scan. I developed a related invention which allows hierarchical relationships to be leveraged to improve the performance of CAD tools like this for detection and segmentation tasks. The second cancer is malignant pleural mesothelioma. It is very different from lung cancer: rather than growing within the lung, mesothelioma grows around the outside of the lung in the pleural cavity, like the rind on an orange. It is a rare cancer, caused by exposure to asbestos fibres. It can take decades from exposure to symptoms developing. In Glasgow many mesothelioma patients worked in the ship-building industry, which relied heavily on asbestos. Although asbestos has been banned in the UK since 1999, its presence in buildings and equipment built before then mean that mesothelioma will remain a problem for years to come. Sadly, asbestos is still being mined and many countries, including the United States, have still not instigated a complete ban. For mesothelioma the main challenge is not detection, but accurate measurement —- without the ability to measure tumour size it is difficult to evaluate potential treatments. We therefore developed a fully automated volumetric assessment of malignant pleural mesothelioma. Performance of the algorithm is shown on a multi-centre test set, where volumetric predictions are highly correlated with an expert annotator (r=0.851, p<0.0001). Region overlap scores between the automated method and an expert annotator exceed those for inter-annotator agreement across a subset of cases. Dice overlap scores of 0.64 and 0.55, by cross-validation and independent testing respectively, were achieved. Future work will progress this algorithm towards clinical deployment for the automated assessment of longitudinal tumour development.

description: The chemical composition of stellar photospheres in mass-transferring binary systems is a precious diagnostic of the nucleosynthesis processes that occur deep within stars, and preserves information on the components history. The binary system u Her belongs to a group of hot Algols with both components being B-stars. We have isolated the individual spectra of the two components by the technique of spectral disentangling of a new series of 43 high-resolution echelle spectra. Augmenting these with an analysis of the Hipparcos photometry of the system yields revised stellar quantities for the components of u Her. For the primary component (the mass-gaining star) we find M_A = 7.88 +/- 0.26 M_sun, R_A = 4.93 +/- 0.15 R_sun and T_eff_A = 21600 +/- 220 K. For the secondary (the mass-losing star) we find M_B = 2.79 +/- 0.12 M_sun, R_B = 4.26 +/- 0.06 R_sun and T_eff_B = 12600 +/- 550 K. A non-LTE analysis of the primary star's atmosphere reveals deviations in the abundances of nitrogen and carbon from the standard cosmic abundance pattern in accord with theoretical expectations for CNO nucleosynthesis processing. From a grid of calculated evolutionary models the best match to the observed properties of the stars in u Her enabled tracing the initial properties and history of this binary system. We confirm that it has evolved according to case A mass transfer. A detailed abundance analysis of the primary star gives C/N = 0.9, which supports the evolutionary calculations and indicates strong mixing in the early evolution of the secondary component, which was originally the more massive of the two. The composition of the secondary component would be a further important constraint on the initial properties of u Her system, but requires spectra of a higher signal to noise ratio.

description: Aiming at evaluating the lifetime of the neutron, we introduce a novel statistical method to analyse the updated compilation of precise measurements including the 2022 dataset of Particle Data Group (PDG). Based on the minimization for the information loss principle, unlike the median statistics method, we apply the most frequent value (MFV) procedure to estimate the neutron lifetime, irrespective of the Gaussian or non-Gaussian distributions. Providing a more robust way, the calculated result of the MFV is $τ_n=881.16^{+2.25}_{-2.35}$ s with statistical bootstrap errors, while the result of median statistics is $τ_n=881.5^{+5.5}_{-3}$ s according to the binomial distribution. Using the different central estimates, we also construct the error distributions of neutron lifetime measurements and find the non-Gaussianity, which is still meaningful.
Languages of rupture : language ideology and the modern novel in Egypt and Turkey

Language ideology

description: In arguing for the central role of language in the creation of the modern nationalist imaginary, scholars of recent literary histories of both Egypt and Turkey have focused a great deal of energy on commonly accepted narratives of linguistic dysfunction. In Egypt and other Arabic speaking countries, the “diglossia problem” has been the locus for conversations about monologic subjectivity, colonial violence, and the counter-hegemonic politics of language. In Turkey, the language reforms are said to have created a mix of cultural aphasia and historical amnesia, brought on in particular by self-inflicted lexical impoverishment. In these accounts, both popular and scholarly, the epistemic ruptures of modernity are embedded in language itself. However, from the perspective of linguistics, both of these apparent dysfunctions are ideological projections, having little to do with either language’s actual communicative functions and everything to do with the social meaning of variation, in a word indexicality. Taking seriously the insights of indexicality, this dissertation argues for a different account of the relationship between language, ideology, and literature. Such an account aims not only to expose the whorfian underpinnings of many previous literary histories, but to recast literature’s relationship to national language as one not of coercion and resistance, but one in which literature itself benefits narratologically from the forms that standard language ideology provides.

description: In this article, we share our experience related to the new photo-injector commissioning at the SPARC\_LAB test facility. The new photo-injector was installed into an existing machine and our goal was not only to improve the final beam parameters themselves but to improve the machine handling in day-to-day operations as well. Thus, besides the pure beam characterization, this article contains information about the improvements, that were introduced into the new photo-injector design from the machine maintenance point of view, and the benefits, that we gained by using the new technique to assemble the gun itself.

Temnothorax pergandei

description: pergandei group overview This group is composed of two species, Temnothorax pergandei and T. bison sp. nov., which are found at all elevations from eastern North America to Central America (Fig. 127). For much of its history, the nominal species of this group was placed in its own subgenus (Dichothorax). All nest collections have been made from soil or dead vegetation on the ground; this appears to be a primarily terrestrial group. United by a strongly depressed propodeum, long setae on all surfaces of the body, and reduced or absent propodeal spines, the members of the pergandei group are unlikely to be confused with any co-occurring Temnothorax species (although they appear to be morphologically convergent with some species of the Mediterranean region of Europe).

description: Over the last century, technology’s impact and, most prominently, the increasing influence of digital technology cannot be overlooked anymore. For all the positives that came with these inventions, many behavioral and social changes left their mark on overall human well-being and health. With the widespread use of artificial light and digital screens, for example, the natural rhythms of humans have suffered. The rhythms-based design approach that is being explored and laid out in the following report addresses the issues of this extensive disruption by considering the environmental, bodily, social and technological rhythms as spaces of design opportunities. This rhythms-based design approach argues for a shift in mindset when designing products, systems and experiences that encourages a systems view of rhythms. It tries to help the designer address disruption and misalignment of environmental, bodily, social and technological rhythms by focusing on the behavioral level of routines, rituals and habits. By focusing on these elements, the designer can take rhythms from an abstract into an observable and actionable realm. The goal for Rhythms+Design (R+D) is to start the conversation within the design community about the importance of rhythms and, consequently, time on the process of design and its impact on the designed artifacts most designers produce. As a discipline, design has had a helpful hand in shaping the last century and most notably the last decades through the advent of digital technologies. R+D as a design approach requires more from the participating designer than it gives. It builds on the ideas of co-creation and the widely established practices of design thinking in its many variations. The rhythms-based approach is used to highlight opportunities and to question assumptions, as well reframe contemporary approaches to design problems.
