AdS correction to the Faddeev-Kulish state: Migrating from the Flat Peninsula

Year: 2022
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The IR finiteness of $\mathcal{S}$-matrix in flat spacetime is tied to the Faddeev-Kulish dressed state, which suggests dressing the Fock space scattering state with the soft photon modes. We instigate a construction for the Faddeev-Kulish dressed state in the language of AdS/CFT. A salient feature of AdS spacetime is that it acquits itself as a quintessential IR regulator. The IR divergences will take shape after taking the zoomed in limit. We explore the Faddeev-Kulish dressed state to account for the AdS radius corrections. The Wilson line dressing stands as a guiding principle in the study of AdS radius-corrected Faddeev-Kulish dressing. We construct the modes of the Wilson line dressed massive scalar field implementing \textit{``vanilla HKLL reconstruction''} since the field is simply free field. This simplification is owing to the use of soft photon modes in the Wilson line dressing. We map the AdS radius-corrected soft photon modes in terms of CFT current operators. We invert this mapping, use the mapping in the Wilson line dressing, and express the AdS radius-corrected Faddeev-Kulish dressed state.

description: We have obtained metallicities of ~ 360 red giant stars distributed in 15 Small Magellanic Cloud (SMC) fields from near-infrared spectra covering the CaII triplet lines using the VLT + FORS2. The errors of the derived [Fe/H] values range from 0.09 to 0.35 dex per star, with a mean of 0.17 dex. The metallicity distribution of the whole sample shows a mean value of [Fe/H] = -1.00 +- 0.02, with a dispersion of 0.32 +- 0.01, in agreement with global mean [Fe/H] values found in previous studies. We find no evidence of a metallicity gradient in the SMC. In fact, on analysing the metallicity distribution of each field, we derived mean values of [Fe/H] = -0.99 +- 0.08 and [Fe/H] = -1.02 +- 0.07 for fields located closer and farther than 4 deg. from the center of the galaxy, respectively. In addition, there is a clear tendency for the field stars to be more metal-poor than the corresponding cluster they surround, independent of their positions in the galaxy and of the clusters' age. We argue that this most likely stems from the field stars being somewhat older and therefore somewhat more metal-poor than most of our clusters.

description: Running a business without having a website is nearly impossible nowadays. Most business owners use content managements sys- tems to manage their websites. Yet, those can pose security risks and provide vulnerabilities for manipulations. With vulnerability notifications, website owners are notified about security risks. To identify common themes with respect to vulnerability notifications and provide deeper insight into the motivations of website owners to react to those notifications, we conducted 25 semi-structured interviews. In compliance with previous research, we could confirm that distrust in unexpected notifications is high and, in contrast to previous research, we suggest that verification possibilities are the most important factors to establish trust in notifications. We also endorse the findings that raising awareness for the severity and the complexity of the problems is crucial to increase remediation rates.
Input for the Second Language Classroom: Some Innovations and Insights
Creators: name: Lew, Adrienne Wai Man
Publisher: name: Studies in Applied Linguistics and TESOL

description: The importance of target language (TL) data in the learning environment has been increasingly recognized by instructional practitioners. One contributing factor is the surge of instructed second language acquisition (ISLA) research since the 1980s, which has resulted in a variety of input-based insights and approaches. Conceptually, Krashen’s (1982, 1985) Input Hypothesis alludes to the essentialness of making input “comprehensible” enough (i+1). That is, learners’ exposure to input must occur at a level just beyond their current capabilities in order for it to be beneficial for acquisition. Pedagogically, focus on form (FonF) (Long, 1991; Long & Robinson, 1998) techniques such as textual enhancement, input flood, and processing instruction (VanPatten, 1996, 2002, 2004) offer practical means for language instructors to make certain physical or formal features of input more salient to classroom learners within a communicative, meaning-focused context. Such meaning-oriented contexts include, for example, processing input for comprehension as part of a larger pedagogic task. That being the case, the past decade of ISLA research has gradually moved beyond the abovementioned focus on the surface, formal features of input to probe into the more intrinsic attributes of L2 input at the phonological, lexical, grammatical and discourse levels.

Enhancing the Role of Meaning in the L2 Classroom: A Cognitive Linguistics Perspective
Creators: name: Sáez, Natalia
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2015

description: From the Cognitive Linguistics (CL) stance, language is a dynamic interplay of complex subsystems composed of symbolic units, and meaning is the driving force behind form. Meaning arises from our physical experience (i.e., embodied cognition), and interacts with culture-specific ways of conceptualizing entities and events through language. As a usage-based model of language acquisition, CL has made significant contributions to second language (L2) pedagogy. Some of these contributions will be briefly discussed below to shed light on how CL research in Second Language Acquisition (SLA) has extended to Instructed SLA.

Information dynamics in the yielding transition of amorphous solids
Creators: name: Popowski, Jared
Publisher: name: University of British Columbia
Year: 2023

description: Many large dynamical systems evolve according to interactions that have a well-defined length scale, such as short-range intermolecular forces in a liquid or the typical domain size in a magnet. However, external conditions can sometimes drive systems to a critical point, where the length scale diverges and measured quantities fluctuate in a scale-free manner, independent of the microscopic details of the system. There are countless examples of critical systems in nature, such as bird flocking, neural networks, financial markets, earthquakes, magnets, and avalanching amorphous solids. The collective behaviors of a system's constituents as it approaches a critical point are increasingly being studied using information theory-based observables, such as the mutual information and transfer entropy, which quantify the reductions in one's uncertainty following system observations. Previous studies have found that certain critical systems exhibit a peak in the mutual information and transfer entropy at the critical point, while the system-wide information flow as quantified by the global transfer entropy peaks strictly in the disordered phase, before the critical point is reached. This is a fascinating albeit still poorly understood result, which implies that one could use the global transfer entropy as a precursor for an upcoming critical point in certain situations. In this thesis, code to estimate the mutual information, transfer entropy and global transfer entropy is developed and tested against a series of analytically solvable models. Focus is then placed on the analysis of avalanche datasets from a mesoscopic model of a shear-driven amorphous solid, which exhibits nonequilibrium criticality at the yielding transition. It is found that the weighted integral of the mutual information provides a valid definition for a correlation length in the amorphous model, and the nature of the correlation length's decay in the high temperature and strain rate regimes are characterized with the aid of a novel avalanche binning procedure. Finally, the transfer entropy and global transfer entropy are applied for the first time to amorphous solids, for the purpose of searching for a precursor to the nonequilibrium brittle-ductile transition, with inconclusive results due to a lack of sufficient statistics.

description: The flow field topology of passenger cars considerably changes under side wind conditions. This changes the surface pressure, aerodynamic force, and drag and performance of a vehicle. In this study, the flow field of a generic passenger vehicle is investigated based on three different side wind angles. The study aimed to identify vortical structures causing changes in the rear pressure distribution. The notchback section of the DrivAer model is evaluated on a scale of 1:4. The wind tunnel tests are conducted in a closed section with a splitter plate at a Reynolds number of 3 million. The side wind angles are 0∘ , 5∘ , and 10∘ . The three-dimensional and time-averaged flow field downstream direction of the model is captured by a stereoscopic particle image velocimetry system performed at several measurement planes. These flow field data are complemented by surface flow visualizations performed on the entire model. The combined approaches provide a comprehensive insight into the flow field at the frontal and side wind inflows. The flow without side wind is almost symmetrical. Longitudinal vortices are evident along the downstream direction of the A-pillar, the C-pillars, the middle part of the rear window, and the base surface. In addition, there is a ring vortex downstream of the vehicle base. The side wind completely changes the flow field. The asymmetric topology is dominated by the windward C-pillar vortex, the leeward A-pillar vortex, and other base vortices. Based on the location of the vortices and the pressure distributions measured in earlier studies, it can be concluded that the vortices identified in the wake are responsible for the local minima of pressure, increasing the vehicle drag.

Nonlocality without nonlocality

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Bell's theorem is purported to demonstrate the impossibility of a local "hidden variable" theory underpinning quantum mechanics. It relies on the well-known assumption of `locality', and also on a little-examined assumption called `statistical independence' (SI). Violations of this assumption have variously been thought to suggest "backward causation", a "conspiracy" on the part of nature, or the denial of "free will". It will be shown here that these are spurious worries, and that denial of SI simply implies nonlocal correlation between spacelike degrees of freedom. Lorentz-invariant theories in which SI does not hold are easily constructed: two are exhibited here. It is conjectured, on this basis, that quantum-mechanical phenomena may be modeled by a local theory after all.
description: 15 pages, 9 figures (some color). Changes in version 2 include (1) a correction to the abstract: Bell's theorem is now said to demonstrate the impossibility of a local hidden variable theory, (2) the "non-spacelike" initial value problem is now the "mixed" initial value problem, (3)the figures should reproduce more clearly.

description: We propose an analytical Landau-Ginzburg theory of the charge density waves coupled with lattice and electronic long-range order parameters. Examples of long-range order include electronic wave function of superconducting Cooper pairs, structural distortions, electric polarization, and magnetization. We formulate the Landau-Ginzburg free energy density as power expansion with respect to the charge density and other long-range order parameters, as well as their spatial gradients, and biquadratic coupling terms. We introduced a biquadratic coupling between the charge density gradient and long-range order parameters, as well as nonlinear higher gradients of the long-range order parameters. The biquadratic gradient coupling is critical to the appearance of different spatially-modulated phases in charge-ordered ferroics and high-temperature superconductors. We derived the thermodynamic conditions for the stability of the spatially-modulated phases, which are the intertwined spatial waves of charge density and lattice/electronic long-range order. The analytical expressions for the energies of different phases, corresponding order parameters, charge density waves amplitudes and modulation periods, obtained in this work, can be employed to guide the comprehensive physical explanation, deconvolution and Bayesian analysis of experimental data on quantum materials ranging from charge-ordered ferroics to high-temperature superconductors.

description: We present a supersymmetric generalization of the MHV vertex expansion for all tree amplitudes in N=4 SYM theory. In addition to the choice of a reference spinor, this super MHV vertex expansion also depends on four reference Grassmann parameters. We demonstrate that a significant fraction of diagrams in the expansion vanishes for a judicious choice of these Grassmann parameters, which simplifies the computation of amplitudes. Even pure-gluon amplitudes require fewer diagrams than in the ordinary MHV vertex expansion. We show that the super MHV vertex expansion arises from the recursion relation associated with a holomorphic all-line supershift. This is a supersymmetric generalization of the holomorphic all-line shift recently introduced in arXiv:0811.3624. We study the large-z behavior of generating functions under these all-line supershifts, and find that they generically provide 1/z^k falloff at (Next-to)^k MHV level. In the case of anti-MHV generating functions, we find that a careful choice of shift parameters guarantees a stronger 1/z^(k+4) falloff. These particular all-line supershifts may therefore play an important role in extending the super MHV vertex expansion to N=8 supergravity.

Far less work has been carried out on L2 pronunciation, compared to skills such as grammar and vocabulary that have received much attention. Most of the instructional materials and practices developed for L2 pronunciation tend to heavily rely on basic intuitive notions suggested by language teachers and researchers, rather than research-based evidence (Derwing & Munro, 2005).

description: Background—A collapse and agitation in a young person comprises many differential diagnoses, but usually does not include a life-threatening basilar thrombosis. Methods and Results—We report the case of a 19-year old woman who presented mainly with a collapse and agitation. CT and CT-angiography yielded distal basilar thrombosis which was successfully treated by intraarterial thrombolysis. MRI confirmed multiple small ischemic lesions in the vertebrobasilar territory. The patient improved quickly and returned to her normal daily activities of life after a few months. Conclusions—Posterior circulation ischemia should be included among the possible differential diagnoses of any acute onset of an agitated or confusional state. Conflicts of interest/Disclosures—None to declare. Ethics—Written informed consent of the patient has been obtained.
Second Language Reading and Instruction

Publisher: name: Studies in Applied Linguistics and TESOL

description: Reading comprehension is a process in which words are interpreted and meaning is created. We read for a variety of reasons: to obtain information, to communicate, and for enjoyment. In order to comprehend or assign meaning to a text, various linguistic, conceptual, reasoning, and metacognitive abilities must work efficiently and simultaneously within the reader (Grabe, 1991; Grabe & Stoller, 2011). Views on second language reading have been greatly influenced by research on first language reading. Second language reading research strives to understand what ‘good’ first language readers do and tries to guide second language instructors, learners, and readers in that direction (Catts & Kamhi, 2005; Grabe, 1991; Grabe & Stoller, 2011). However, in order to effectively do so, it is essential to understand what reading is and its multifaceted nature, both in a reader’s first as well as second language.

description: We present a detailed investigation of SBS1150+599A, a close binary star hosted by the planetary nebula PN G135.9+55.9 (TS01, Stasinska et al, 2009). The nebula, located in the Galactic halo, is the most oxygen-poor one known to date and is the only one known to harbor a double degenerate core. We present XMM-Newton observations of this object, which allowed the detection of the previously invisible component of the binary core, whose existence was inferred so far only from radial velocity and photometric variations. The parameters of the binary system were deduced from a wealth of information via three independent routes using the spectral energy distribution (from the infrared to X-rays), the light and radial velocity curves, and a detailed model atmosphere fitting of the stellar absorption features of the optical/UV component. We find that the cool component must have a mass of 0.54+/-0.2 Msun, an average effective temperature, Teff, of 58000+/-3000 K, a mean radius of 0.43+/-0.3 Rsun, a gravity log g=5.0+/-0.3, and that it nearly fills its Roche lobe. Its surface elemental abundances are found to be: 12 + log He/H = 10.95+/-0.04 dex, 12 + log C/H = 7.20+/-0.3 dex, 12 + log N/H < 6.92 and 12 + log O/H < 6.80, in overall agreement with the chemical composition of the planetary nebula. The hot component has Teff = 160-180 kK, a luminosity of about ~10e4 Lsun and a radius slightly larger than that of a white dwarf. It is probably bloated and heated as a result of intense accretion and nuclear burning on its surface in the past. The total mass of the binary system is very close to Chandrasekhar limit. This makes TS01 one of the best type Ia supernova progenitor candidates. We propose two possible scenarios for the evolution of the system up to its present stage.

The 87Rb condensates were confined in an optical trap and selectively prepared in various spin states in the F=2 manifold at a magnetic field of 3.0 G. Measured atom loss rates are found to depend on spin states of colliding atoms. We measured two fundamental loss coefficients for two-body inelastic collisions with the total spin of 0 and 2; the coefficients determine loss rates for all the spin pairs. The experimental results for mixtures of all the spin combinations are in good agreement with numerical solutions of the Gross-Pitaevskii equations that include the effect of a magnetic field gradient.

description: Since the late ′60s, the field of second language acquisition (SLA) has grown enormously. Throughout its development, SLA researchers have investigated a wide range of issues including the processes involved in second language learning, as well as the psycholinguistic, affective and social factors that influence its success or failure (Spada, 2014). In light of SLA’s relevance and applicability to language teaching, recently a growing number of researchers have taken an interest in second language (L2) learning in classroom settings (Spada, 2014). The term Instructed SLA (ISLA) is currently used to indicate “theory and research that pertain directly to the L2 classroom” (Loewen, 2014, p. 1). One of the main goals of ISLA is to examine which particular types of instruction are more pedagogically effective for a particular learning target. In this short commentary, this question will be investigated in the domain of vocabulary learning. Accordingly, research on instructed vocabulary learning will be briefly reviewed to reveal several insights pertaining to L2 vocabulary pedagogy.

description: The intersection of generative AI and art is a fascinating area that brings both exciting opportunities and significant challenges, especially when it comes to identifying synthetic artworks. This study takes a unique approach by examining diffusion-based generative models in the context of Indian art, specifically focusing on the distinctive style of Jamini Roy. To explore this, we fine-tuned Stable Diffusion 3 and used techniques like ControlNet and IPAdapter to generate realistic images. This allowed us to create a new dataset that includes both real and AI-generated artworks, which is essential for a detailed analysis of what these models can produce. We employed various qualitative and quantitative methods, such as Fourier domain assessments and autocorrelation metrics, to uncover subtle differences between synthetic images and authentic pieces. A key takeaway from recent research is that existing methods for detecting deepfakes face considerable challenges, especially when the deepfakes are of high quality and tailored to specific cultural contexts. This highlights a critical gap in current detection technologies, particularly in light of the challenges identified above, where high-quality and culturally specific deepfakes are difficult to detect. This work not only sheds light on the increasing complexity of generative models but also sets a crucial foundation for future research aimed at effective detection of synthetic art.

“Autism in practice” : establishing, maintaining, and understanding friendships among autistic adults in British Columbia
Creators: name: Brake, Jad
Publisher: name: University of British Columbia
Year: 2023

description: This dissertation explores the lived experiences of autistic adults living in British Columbia in Canada and examines how they socialize and experience friendship relations. Based on 14 months of ethnographic fieldwork, this work answers the following: 1) What are autistics’ experiences of the physiological barriers that may affect autistics’ social interaction, communication, and relationships? how do autistics describe and deal with these barriers? 2) How do autistics describe their relationships with the people they call “friends,” and how do they create and sustain these relationships? 3) What can we learn from the practices of friendship among autistics, and their coping strategies for everyday challenges, about the everyday and life experience of being an autistic? By answering these questions, this study provides an anthropological analysis that illuminates the perceptual-physical grounding of experience and demonstrates how aspects of embodiment construct as well as explain relatedness and sociability, and the processes of developing intersubjectivity and morality in autistics’ friendships. Specifically, it shows that there are three main issues that explain friendship and sociability among autistics: Unusual sensory perception, social communication difficulties, and personal histories and negative lived experiences. By adopting diverse sensory, communicative, and social coping strategies, autistics constantly adapt their previous sensory, communicative, and social experiences to particular social environments, and try to develop effective communication and intersubjectivity that enable them to engage in friendships and intimate relationships. These ongoing adaptative processes, which reflect the stress of social interaction and the intense desire for it, produce distinctive patterns and perceptions of friendship among autistics and generate a different way of practicing friendship. Accordingly, to understand what autistics define as “friendship,” I argue, this form of relatedness must be examined in the broader context of personal difficulties, particularly sensory-embodied experiences, physical environments, social-cultural attitudes and reactions, and the lived experiences of autistics, all of which intersect and construct the nature of friendship among autistics. By contextualizing friendship, my findings question assumptions about autism as a lack of interest in social interaction, and contribute to an understanding of autism as a complex corporeal and social experience, rather than a purely medical or neurodevelopmental condition.

description: The 3-D Bohr-Mottelson Hamiltonian for $γ$-rigid prolate isotopes, known as $X(3)$, is solved via inverse square potential having only one free parameter, $β_{0}$. The exact form of the wave functions and the energy spectra are obtained as a function of the free parameter of the potential that determines the changes in the spectra ratios and the $B(E2)$. Since $X(3)$ is an exactly separable $γ$-rigid version of $X(5)$, the solutions are compared with the $X(5)$ model and some new set of equations that show the relationships between the two models are stated. In other to show the dynamical symmetry nature of the solutions, the entire solutions from $β_{0}=0$ to $β_{0}=\infty$ are compared with $U(5)$, $X(5)$ and $SU(3)$. The solutions spread from the region around $U(5)$ over $X(5)$ and approach $SU(3)$ at $β_{0}=\infty$. The exact solutions obtained via variational procedure are compared favourably with some existing $X(3)$ models found in the literature. The strong agreement between the present model and $X(3)$ via infinite square well potential is discussed. Twelve best critical point isotopes, $^{102}$Mo, $^{104-108}$Ru, $^{120-126}$Xe, $^{148}$Nd, $^{184-188}$Pt are chosen for experimental realization of the model and moderate agreements are recorded. An excellent agreement which appears in the first $β$-excited state in the comparison of the present model with three $N=90$ isotones: $^{150}$Nd, $^{154}$Gd, and $^{156}$Dy, known to be $X(5)$ candidates, suggests that the present model compensates the $X(5)$ models whose predictions are excellent in the ground states but moderately bad in the first $β$-excited states.

description: Born in the late 1960s, second language acquisition (SLA) is a field of study that addresses how non-native languages are learned, either in naturalistic or instructed settings. As a “burgeoning subdomain” of SLA (Ortega, 2013, p. 5) that emerged in the 1980s, instructed second language acquisition (ISLA) focuses on the latter, attempting to unveil the effects of instructional intervention, i.e., second language (L2) pedagogy, on the process of L2 learning. As such, a rich body of theoretical and empirical works that bears direct relevance to the L2 classroom constitutes ISLA, distinguishing it from related sub-domains within the more general discipline of second language acquisition.

description: GALEV evolutionary synthesis models describe the evolution of stellar populations in general, of star clusters as well as of galaxies, both in terms of resolved stellar populations and of integrated light properties over cosmological timescales of > 13 Gyr from the onset of star formation shortly after the Big Bang until today. For galaxies, GALEV includes a simultaneous treatment of the chemical evolution of the gas and the spectral evolution of the stellar content, allowing for what we call a chemically consistent treatment: We use input physics (stellar evolutionary tracks, stellar yields and model atmospheres) for a large range of metallicities and consistently account for the increasing initial abundances of successive stellar generations. Here we present the latest version of the galev evolutionary synthesis models that are now interactively available at www.galev.org. We review the currently used input physics, and also give details on how this physics is implemented in practice. We explain how to use the interactive web-interface to generate models for user-defined parameters and also give a range of applications that can be studied using GALEV, ranging from star clusters, undisturbed galaxies of various types E ... Sd to starburst and dwarf galaxies, both in the local and the high-redshift universe.

subject: Health equity

description: Globally, health inequities persist for Indigenous peoples. Socio-historic-political circumstances, including colonisation, contribute. Health professions courses now mandate Indigenous health curriculum. However, little was known about educator and student interactions with curriculum. This research examined impacts of Indigenous health curriculum on health professional students and the experiences and perspectives of educators. The study revealed problematic centring of non-Indigenous peoples’ and de-centring of Indigenous peoples in curriculum implementation. Current learning and teaching responses provide an insufficient response to health inequity. Development of student and educator skills to mitigate inequity is needed, while decentring non-Indigenous people, and respecting Aboriginal leadership throughout curriculum implementation.
New reaction approach to reflect exotic structure of hadronic molecular state

description: With the accumulation of experimental data, more and more exotic hadrons are observed. Among the interpretations of these exotic hadrons, molecular state and compact multiquark are two of the most popular pictures. However, it is still difficult to determine the structure of an exotic hadron. In this work, we propose a possible way to detect the internal structure of an exotic state. When a molecular state composed of two consistent hadrons is attacked by another particle, one of the constituents should be kicked out while another quasifree constituent stays almost unaffected. It is different from a compact multiquark which has no obvious subcluster. In this work, taking the $X(3872)$ as an example, we perform a Dalitz plot analysis of such reaction to find the effect of the different internal structures. Under the assumption of the $X(3872)$ as a molecular state or a compact tetraquark state, with the help of the effective Lagrangians, the Dalitz plot and the invariant mass spectrum are estimated with different total invariant mass of three final particles, and the effect of different binding energies is also discussed. Obvious event concentration can be observed as strips in the Dalitz plot and sharp peaks in the invariant mass spectrum for the $X(3872)$ with a small binding energy under the molecular state picture, while such concentration cannot be observed under the compact tetraquark picture. Such phenomenon can be applied to identify the internal structure of a new hadron state.

description: TANAMI (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry) is a monitoring program to study the parsec-scale structures and dynamics of relativistic jets in active galactic nuclei (AGN) of the Southern Hemisphere with the Long Baseline Array and associated telescopes. Extragalactic jets south of -30 degrees declination are observed at 8.4 GHz and 22 GHz every two months at milliarcsecond resolution. The initial TANAMI sample is a hybrid radio and gamma-ray selected sample since the combination of VLBI and gamma-ray observations is crucial to understand the broadband emission characteristics of AGN.

description: Starting from the relativistic Brueckner-Hartree-Fock theory for nuclear matter and the Dyson-Schwinger equation approach for quark matter, the possible hadron-quark phase transition in the interior of a neutron star is explored. The first-order phase transition and crossover are studied by performing the Maxwell construction and three-window construction respectively. The mass-radius relation and the tidal deformability of the hybrid star are calculated and compared to the joint mass-radius observation of a neutron star and the constraints from gravitational wave detection. For the Maxwell construction, no stable quark core is found in the interior of a neutron star. For the three-window construction, the parameters of the smooth interpolation function are chosen in such a way to keep the thermodynamic stability and lead to a moderate crossover density region. To support a two-solar-mass neutron star under the three-window construction, the effective width of medium screening effects in quark matter should be around $0.35$ GeV.

description: Today, six humans in ten have no access to medical care or do not adhere to it. Achieving collective health requires a mindset shift from competitive models creating dependency (medtech business) to solidarity-driven models building communal capacity (health commons). Here, we present 15 initiatives created by open networks of interdisciplinary contributors (peer production); who iteratively co-create and document projects (agile development) that can be freely used, repaired, studied, reproduced and adapted by communities (libre and open-source licences) at fair prices or no cost. As resources are mutualized to avoid redundancies, costs can be cut by ten to hundred times in comparison to IP-driven models. Such commons also foster local capacity building, as various communities can take responsibility to validate, produce and distribute the projects (crowd/peer production). Disease management: valve for mask (Isinnova Charlotte), oxygen concentrator (M19 O2), ventilation machine (OpenVent), ventilator co-design platform (Polyvent), genetic material development (OpenPCR), repurposing vaccines (OSPF OpenVax), repurposing treatments (DNDi AntiCov). Disease prevention: hand rub (Geneva Hand Hygiene Model), Pulmonary Toolkit – 3D lung modeling (Pulmonary Toolkit), transparent mask (BEclear), air quality sensor (LogAir), digital health ecosystem (GNU Health). Health promotion: fun respiratory care (Breathing Games), traditional medicine (CEMI), social support network (Art Hives). Editable version
