description: Investigations of three-body nuclear systems using pionless effective field theory ($\mathrm{EFT}_{\notπ}$) are reviewed. The history of $\mathrm{EFT}_{\notπ}$ in $nd$ and $pd$ scattering is briefly discussed and emphasis put on the use of strict perturbative techniques. In addition renormalization issues appearing in $pd$ scattering are also presented. Bound state calculations are addressed and new perturbative techniques for describing them are highlighted. Three-body breakup observables in $nd$ scattering are also considered and the utility of $\mathrm{EFT}_{\notπ}$ for addressing them.

description: Cette contribution présente le processus de construction d’un nouveau canevas pour l’évaluation certificative en éducation physique à l’école primaire de Genève. Il représente l’aboutissement d’une première étape d’une démarche collaborative qui a réuni des représentant·es de l’éducation physique de Genève de trois institutions : Direction Générale de l’Enseignement Obligatoire (DGEO), Université de Genève (Unige), Maitre∙sses de Disciplines Artistiques et Sportives du primaire (MDAS). Cette initiative résulte d’une évolution du contexte de l’éducation physique à Genève résultant sur différents dysfonctionnements du canevas actuel. Ainsi, dans la première section du texte, nous montrons comment le canevas actuel découle du projet Rénovation (1994) de l’école primaire ainsi que de l’introduction du plan d’études romand (CIIP, 2000). Nous relevons ensuite comment l’évolution du contexte a entrainé la nécessité de poursuivre cette réflexion afin de faire correspondre les prescriptions de certifications aux enjeux scientifiques, institutionnels et pratiques actuels. Dans la seconde section, nous exposons le cadrage théorique sur lequel nous nous appuyons pour prendre en compte l’évaluation lorsque l’on enseigne dans une approche par compétences ainsi que les présupposés épistémologiques qui s’inscrivent dans une tradition d’éducation à la culture physique et sportive (Forest et al., 2018). Enfin, nous présentons le nouveau canevas d’évaluation certificative en étayant les choix que nous avons opérés pour ce qui concerne la structure et les contenus d’enseignement qui nous semblent pertinents à être évalués (et donc enseignés). Dans cette perspective, les apports en termes de notation constructive (Pasquini, 2021) ont largement contribué à la structuration du canevas.

description: We report on the discovery of extended Ly-alpha nebulae at z~3.3 in the Hubble Ultra Deep Field (HUDF, ~ 40 kpc X 80 kpc) and behind the Hubble Frontier Fields galaxy cluster MACSJ0416 (~ 40kpc), spatially associated with groups of star-forming galaxies. VLT/MUSE integral field spectroscopy reveals a complex structure with a spatially-varying double peaked Ly-alpha emission. Overall, the spectral profiles of the two Ly-alpha nebulae are remarkably similar, both showing a prominent blue emission, more intense and slightly broader than the red peak. From the first nebula, located in the HUDF, no X-ray emission has been detected, disfavoring the possible presence of AGNs. Spectroscopic redshifts have been derived for 11 galaxies within two arcsec from the nebula and spanning the redshift range 1.037

description: Graphic Processing Units (GPUs) have become ubiquitous in scientific computing. However, writing efficient GPU kernels can be challenging due to the need for careful code tuning. To automatically explore the kernel optimization space, several auto-tuning tools - like Kernel Tuner - have been proposed. Unfortunately, these existing auto-tuning tools often do not concern themselves with integration of tuning results back into applications, which puts a significant implementation and maintenance burden on application developers. In this work, we present Kernel Launcher: an easy-to-use C++ library that simplifies the creation of highly-tuned CUDA applications. With Kernel Launcher, programmers can capture kernel launches, tune the captured kernels for different setups, and integrate the tuning results back into applications using runtime compilation. To showcase the applicability of Kernel Launcher, we consider a real-world computational fluid dynamics code and tune its kernels for different GPUs, input domains, and precisions.

description: Dynamical masses of giant planets and brown dwarfs are critical tools for empirically validating substellar evolutionary models and their underlying assumptions. We present a measurement of the dynamical mass and an updated orbit of PZ Tel B, a young brown dwarf companion orbiting a late-G member of the $β$ Pic moving group. PZ Tel A exhibits an astrometric acceleration between Hipparcos and Gaia EDR3, which enables the direct determination of the companion's mass. We have also acquired new Keck/NIRC2 adaptive optics imaging of the system, which increases the total baseline of relative astrometry to 15 years. Our joint orbit fit yields a dynamical mass of $27^{+25}_{-9} \, M_{\mathrm{Jup}}$, semi-major axis of $27^{+14}_{-4} \, \mathrm{au}$, eccentricity of $0.52^{+0.08}_{-0.10}$, and inclination of $91.73^{+0.36}_{-0.32} {}^\circ$. The companion's mass is consistent within $1.1σ$ of predictions from four grids of hot-start evolutionary models. The joint orbit fit also indicates a more modest eccentricity of PZ Tel B than previous results. PZ Tel joins a small number of young (${<}200 \, \mathrm{Myr}$) systems with benchmark substellar companions that have dynamical masses and precise ages from moving group membership.

description: Predictive power in theoretical nuclear physics has been a major concern in the study of nuclear structure and reactions. The Effective Field Theory (EFT) based on chiral expansions provides a model independent hierarchy for many body forces at long distances but their predictive power may be undermined by the regularization scheme de- pendence induced by the counterterms and encoding the short distances dynamics which seem to dominate the uncertainties. We analyze several examples including zero energy NN scattering or perturbative counterterm-free peripheral scattering where one would ex- pect these methods to work best and unveil relevant systematic discrepancies when a fair comparison to the Granada-2013 NN-database and partial wave analysis is undertaken.

description: HIV infection remains a major public health burden, with 2955 new diagnoses in the UK in 2021 (GOV UK). It follows that improved options for prevention and treatment of HIV infection are a public health priority. On 15 December 2021, NICE updated its guidelines to recommend offering PrEP (Human Pre-Exposure Prophylaxis) to individuals at high risk of HIV infection for the first time. This includes some groups of men who have sex with men (MSM), intravenous drug users (IVDU), and sex workers. PrEP has transformed public health approaches to HIV, with an estimated 86% reduction in HIV transmission when used correctly. PrEP consists of oral anti-retroviral agents, and while different combinations of anti-retroviral agents have been used historically, PrEP in the UK currently consists of a tenofovir-emtricitabine combination regimen, branded as Truvada®. To ensure that our investigation is of maximal clinical relevance, we have clearly defined PrEP as a tenofovir-emtricitabine combination regimen, reflecting the formulation currently recommended in the UK. We will not analyse PrEP regimens that do not include this combination regimen. Despite the clear benefits of HIV PrEP, there has been some concern about associated adverse events (AEs). Although some systematic reviews have evaluated the safety of PrEP, these have focused on a few specific classes of AE (such as renal damage and bone fractures) and not others (such as nausea and liver damage). Additionally, current systematic reviews have not compared the risk profiles of AEs for different dosage regimens (PrEP can be taken “on demand” as well as daily). Importantly, they have not included data from recent large-scale observational trials since widespread PrEP licensure. We therefore seek to evaluate adverse events after PrEP, and to compare the risk profiles of daily vs “on-demand” regimens, using data from both randomised controlled trials (RCTs) and observational studies, with a view to providing individuals with the best possible evidence to inform them about whether PrEP is a suitable option for them, and, if so, which regimen of PrEP is most appropriate.

Alfvénic motions arising from asymmetric acoustic wave drivers in solar magnetic structures

description: Alfvénic motions are ubiquitous in the solar atmosphere and their observed properties are closely linked to those of photospheric p-modes. However, it is still unclear how a predominantly acoustic wave driver can produce these transverse oscillations in the magnetically dominated solar corona. In this study we conduct a 3D ideal MHD numerical simulation to model a straight, expanding coronal loop in a gravitationally stratified solar atmosphere which includes a transition region and chromosphere. We implement a driver locally at one foot-point corresponding to an acoustic-gravity wave which is inclined by $θ= 15^{\circ}$ with respect to the vertical axis of the magnetic structure and is similar to a vertical driver incident on an inclined loop. We show that transverse motions are produced in the magnetic loop, which displace the axis of the waveguide due to the breaking of azimuthal symmetry, and study the resulting modes in the theoretical framework of a magnetic cylinder model. By conducting an azimuthal Fourier analysis of the perturbed velocity signals, the contribution from different cylindrical modes is obtained. Furthermore, the perturbed vorticity is computed to demonstrate how the transverse motions manifest themselves throughout the whole non-uniform space. Finally we present some physical properties of the Alfvénic perturbations and present transverse motions with velocity amplitudes in the range of $0.2-0.75$ km s$^{-1}$ which exhibit two distinct oscillation regimes corresponding to $42$ s and $364$ s, where the latter value is close to the period of the p-mode driver in the simulation.

description: The pandemic has led to a shift in views on technology's role in learning, recognising its potential to foster continuous learning, engagement, and communication. This study investigates the impact of distance learning on education management and their implications on school principals' attitudes towards remote learning in the UAE. Remote education significantly impacts school management, with objectives expanding into blended learning, technical proficiency, and community development. This futuristic approach emphasises adaptability, flexibility, and the integration of technology in the changing educational landscape. This study, unlike others, focusses on the attitudes of principals towards online education to identify the constraints and gather data about managing remote learning and the implication for principals as educational leaders. The mixed methods analyses give the insights into the scale and implications of moving to remote learning on school principals and education management in the UAE.

description: During their formation phase stars gain most of their mass in violent episodic accretion events, such as observed in FU Orionis (FUor) and EXor stars. V346 Normae is a well-studied FUor that underwent a strong outburst beginning in $\sim1980$. Here, we report photometric and spectroscopic observations which show that the visual/near-infrared brightness has decreased dramatically between the 1990s and 2010 ($ΔR\approx10.9^{\rm m}$, $ΔJ\approx7.8^{\rm m}$, $ΔK\approx5.8^{\rm m}$). The spectral properties of this fading event cannot be explained with variable extinction alone, but indicate a drop in accretion rate by 2-3 orders of magnitude, marking the first time that a member of the FUor class has been observed to switch to a very low accretion phase. Remarkably, in the last few years (2011-2015) V346 Nor has brightened again at all near-infrared wavelengths, indicating the onset of a new outburst event. The observed behaviour might be consistent with the clustered luminosity bursts that have been predicted by recent gravitational instability and fragmentation models for the early stages of protostellar evolution. Given V346 Nor's unique characteristics (concerning outburst duration, repetition frequency, and spectroscopic diagnostics), our results also highlight the need for revisiting the FUor/EXor classification scheme.

The period--luminosity relation for Mira variables in the Milky Way using Gaia DR3: a further distance anchor for $H_0$

description: Gaia DR3 parallaxes are used to calibrate preliminary period--luminosity relations of O-rich Mira variables in the 2MASS $J$, $H$ and $K_s$ bands using a probabilistic model accounting for variations in the parallax zeropoint and underestimation of the parallax uncertainties. The derived relations are compared to those measured for the Large and Small Magellanic Clouds, the Sagittarius dwarf spheroidal galaxy, globular cluster members and the subset of Milky Way Mira variables with VLBI parallaxes. The Milky Way linear $JHK_s$ relations are slightly steeper and thus fainter at short period than the corresponding LMC relations suggesting population effects in the near-infrared are perhaps larger than previous observational works have claimed. Models of the Gaia astrometry for the Mira variables suggest that, despite the intrinsic photocentre wobble and use of mean photometry in the astrometric solution of the current data reduction, the recovered parallaxes should be on average unbiased but with underestimated uncertainties for the nearest stars. The recommended Gaia EDR3 parallax zeropoint corrections evaluated at $ν_\mathrm{eff}=1.25\,μ\mathrm{m}^{-1}$ require minimal ($\lesssim5\,μ\mathrm{as}$) corrections for redder five-parameter sources, but over-correct the parallaxes for redder six-parameter sources, and the parallax uncertainties are underestimated, at most by a factor $\sim1.6$ at $G\approx12.5\,\mathrm{mag}$. The derived period--luminosity relations are used as anchors for the Mira variables in the Type Ia host galaxy NGC 1559 to find $H_0=(73.7\pm4.4)\,\mathrm{km\,s}^{-1}\mathrm{Mpc}^{-1}$.

Can Protostellar Outflows Set Stellar Masses?

description: The opening angles of some protostellar outflows appear too narrow to match the expected core-star mass efficiency SFE = 0.3-0.5 if outflow cavity volume traces outflow mass, with a conical shape and a maximum opening angle near 90 deg. However, outflow cavities with paraboloidal shape and wider angles are more consistent with observed estimates of the SFE. This paper presents a model of infall and outflow evolution based on these properties. The initial state is a truncated singular isothermal sphere which has mass $\approx$1 $M_\odot$, free fall time $\approx$80 kyr, and small fractions of magnetic, rotational, and turbulent energy. The core collapses pressure-free as its protostar and disk launch a paraboloidal wide-angle wind. The cavity walls expand radially and entrain envelope gas into the outflow. The model matches SFE values when the outflow mass increases faster than the protostar mass by a factor 1 - 2, yielding protostar masses typical of the IMF. It matches observed outflow angles if the outflow mass increases at nearly the same rate as the cavity volume. The predicted outflow angles are then typically $\sim$50 deg as they increase rapidly through the stage 0 duration of $\sim$40 kyr. They increase more slowly up to $\sim$110 deg during their stage I duration of $\sim$70 kyr. With these outflow rates and shapes, model predictions appear consistent with observational estimates of typical stellar masses, SFEs, stage durations, and outflow angles, with no need for external mechanisms of core dispersal.

description: Stationary entanglement in a four-mode optomechanical system, especially under roomtemperature, is discussed. In this scheme, when the coupling strengths between the two target modes and the mechanical resonator are equal, the results cannot be explained by the Bogoliubov mode- based scheme. This is related to the idea of quantum-mechanics-free subspace, which plays an important role when the thermal noise of the mechanical modes is considered. Significantly prominent steady-state entanglement can be available under room-temperature.

Heavy traffic analysis of roving server networks

Publisher: name: arXiv
Year: 2016

subject: FOS: Mathematics

description: This paper studies the heavy-traffic (HT) behaviour of queueing networks with a single roving server. External customers arrive at the queues according to independent renewal processes and after completing service, a customer either leaves the system or is routed to another queue. This type of customer routing in queueing networks arises very naturally in many application areas (in production systems, computer- and communication networks, maintenance, etc.). In these networks, the single most important characteristic of the system performance is oftentimes the path time, i.e. the total time spent in the system by an arbitrary customer traversing a specific path. The current paper presents the first HT asymptotic for the path-time distribution in queueing networks with a roving server under general renewal arrivals. In particular, we provide a strong conjecture for the system's behaviour under HT extending the conjecture of Coffman et al. [E.G. Coffman Jr., A.A. Puhalskii, M.I. Reiman 1995 and 1998] to the roving server setting of the current paper. By combining this result with novel light-traffic asymptotics we derive an approximation of the mean path-time for arbitrary values of the load and renewal arrivals. This approximation is not only highly accurate for a wide range of parameter settings, but is also exact in various limiting cases.

description: Pathogenic variants in SPART cause Troyer syndrome, characterized by lower extremity spasticity and weakness, short stature and cognitive impairment, and a severe mitochondrial impairment. Herein, we report the identification of a role of Spartin in nuclear-encoded mitochondrial proteins. SPART biallelic missense variants were detected in a 5-year-old boy with short stature, developmental delay, muscle weakness with impaired walking distance. Patient-derived fibroblasts showed an altered mitochondrial network, decreased mitochondrial respiration and increased mitochondrial reactive oxygen species and altered Ca2+ versus control cells. We investigated the mitochondrial import of nuclear-encoded proteins in these fibroblasts and in another cell model carrying a SPART loss-of-function mutation. In both cell, models the mitochondrial import was impaired, leading to a significant decrease in different proteins, including two key enzymes involved in CoQ10 (CoQ) synthesis, COQ7 and COQ9, with a severe reduction in CoQ content, versus control cells. CoQ supplementation restored cellular ATP levels to the same extent shown by the re-expression of wild-type SPART, suggesting CoQ treatment as a promising therapeutic approach for patients carrying mutations in SPART.

description: The detection of split main sequences (MSs) associated with young clusters ($\lesssim$600 Myr) has caught lots of attention. A prevailing scenario is that a bimodality of stellar rotation distribution drives the MS bifurcation. Nevertheless, the origin of the stellar rotation dichotomy remains unclear. Hypotheses involving tidally-locked binaries or blue straggler stars (BSSs) are proposed to explain the observed split MSs. This work examines if the long-term dynamical evolution of star clusters can produce the observed split MSs, through high-performance $N$-body simulation. As a prototype example, the young massive cluster NGC 1856 exhibits an apparent MS bifurcation. Our simulation reports that at the age of NGC 1856, tidally-locked binaries are fully mixed with single stars. This is consistent with the observation that there is no significant spatial difference between blue MS and red MS stars. However, we find that only high mass-ratio binaries can evolve to the tidally-locked phase at the age of the NGC 1856. These tidally-locked binaries will populate a much redder sequence than the MS of single stars rather than a blue MS, which is inconsistent with the hypothesis. The number of tidally-locked binaries cannot account for the observation. Our simulation shows that BSSs produced by binary interactions do populate the blue periphery in the color-magnitude diagram, and their spatial distribution shows a similar pattern of single stars. However, the number of BSSs does not fit the observation.

description: The aims of this study were twofold: firstly, to compare core stability and knee joint loading between sidestepping experts and nonexperts; secondly, to determine core predictors of knee joint loading. Thirteen handball male players (experts) and fourteen karatekas (nonexperts) performed six unanticipated 45{\textdegree} sidestepping manoeuvers, while trunk and pelvis 3D kinematics as well as ground reaction forces were measured, and peak knee abduction moment (PKAM) was determined. Student t-tests enabled a comparison of both groups and a linear mixed model approach was used to identify PKAM predictors. Sidestepping experts demonstrated significantly lower pelvis rotation towards the new movement direction at the initial contact than nonexperts (4.9{\textdegree} vs. 10.8{\textdegree}) and higher PKAM (0.539 vs. 0.321 Nm/kg-bwt). Trunk medial lean, trunk axial rotation and pelvis anterior tilt at the initial contact predicted PKAM, while trunk axial rotation, pelvis medial lean and posterior ground reaction force predicted PKAM during the weight acceptance phase. Despite higher PKAM, handball players might not be at a higher risk of anterior cruciate ligament injury as the knee joint loading remained at a relatively low level during this sidestepping task. Core stability, in its three dimensions, is a key determinant of knee joint loading.

description: Mergers of two stellar origin black holes are a prime source of gravitational waves and are under intensive investigations. One crucial ingredient in their modeling has so far been neglected. Pair-instability pulsation supernovae with associated severe mass loss may suppress formation of massive black holes, decreasing black hole merger rates for the highest black hole masses. The mass loss associated with pair-instability pulsation supernovae limits the Population I/II stellar-origin black hole mass to 50 Msun, in tension with earlier predictions that the maximum black hole mass could be as high as 100 Msun. Suppression of double black hole merger rates by pair-instability pulsation supernovae is negligible for our evolutionary channel. Our standard evolutionary model with inclusion of pair-instability pulsation supernovae and with pair-instability supernovae is fully consistent with the LIGO detections of black hole mergers: GW150914, GW151226 and LVT151012. The LIGO observations seem to exclude high (>400 km/s) BH natal kicks. We predict the detection of several up to 60 BH-BH mergers with total mass 10--150 Msun (most likely range: 20--80 Msun) in the forthcoming 60 effective days of LIGO O2 observations.

description: As the most abundant element in the universe after hydrogen and helium, oxygen plays a key role in planetary, stellar, and galactic astrophysics. Its abundance is especially influential on stellar structure and evolution, and as the dominant opacity contributor at the base of the Sun's convection zone it is central to the discussion around the solar modelling problem. However, abundance analyses require complete and reliable sets of atomic data. We present extensive atomic data for O I, by using the multiconfiguration Dirac-Hartree-Fock and relativistic configuration interaction methods. Lifetimes and transition probabilities for radiative electric dipole transitions are given and compared with results from previous calculations and available measurements. The accuracy of the computed transition rates is evaluated by the differences between the transition rates in Babushkin and Coulomb gauges, as well as by a cancellation factor analysis. Out of the 989 computed transitions in this work, 205 are assigned to the accuracy classes AA-B, that is, with uncertainties less than 10%, following the criteria defined by the National Institute of Standards and Technology Atomic Spectra Database. We discuss the influence of the new log(gf) values on the solar oxygen abundance and ultimately advocate $\logε_{\mathrm{O}}=8.70\pm0.04$.

description: Построение дорожных карт ТРИЗ-проектов, указывающих последовательность применения инструментов ТРИЗ, по важности можно сравнить с АРИЗ для решения изобретательских задач. Известны методики, в которых делается попытка описания различных универсальных дорожных карт для нескольких типов ТРИЗ-проектов, но они с одной стороны слишком сложны, так как стремятся описать максимально детально возможные варианты выполнения проектов, а с другой не могут учесть все особенности того или иного ТРИЗ-проекта, предлагая использовать не самые эффективные для данного проекта виды анализа или, наоборот, не предлагая применять важные для данного проекта инструменты ТРИЗ. Автор на основе опыта выполнения ТРИЗ-проектов, опыта массового внедрения ТРИЗ и управления портфелями ТРИЗ-проектов на промышленных предприятиях предлагает новый итерационный метод построения дорожных карт ТРИЗ-проектов на основе анализа полноты формулировки исходной и уточненной проблемной ситуации. Разработанные автором алгоритмы формализуют (оцифровывают) уровень полноты текущего описания рассматриваемой проблемы и предлагают следующие виды анализа и применения инструментов ТРИЗ, позволяющие сделать более полное описание исходной проблемы и найти решение сформулированных противоречий требований к рассматриваемой системе. Предлагаемый автором подход позволяет повысить эффективность планирования ТРИЗ-проектов в условиях массового внедрения ТРИЗ на предприятиях промышленности при низкой опытности руководителей ТРИЗ-проектов, а также открывает возможность автоматизации процесса планирования ТРИЗ-проектов, что повлечет за собой снижение временных затрат на планирование проектов. В данной работе раскрывается суть разработанного автором алгоритма формирования дорожных карт для ТРИЗ-проектов, демонстрируется на примерах работа алгоритма конструктора дорожных карт, выполненный на основе разработанного алгоритма, а также приводятся результаты верификации работы прототипа и алгоритма в проектной деятельности.

description: The pressure exerted by massive stars' radiation fields is an important mechanism regulating their formation. Detailed simulation of massive star formation therefore requires an accurate treatment of radiation. However, all published simulations have either used a diffusion approximation of limited validity; have only been able to simulate a single star fixed in space, thereby suppressing potentially-important instabilities; or did not provide adequate resolution at locations where instabilities may develop. To remedy this we have developed a new, highly accurate radiation algorithm that properly treats the absorption of the direct radiation field from stars and the re-emission and processing by interstellar dust. We use our new tool to perform three-dimensional radiation-hydrodynamic simulations of the collapse of massive pre-stellar cores with laminar and turbulent initial conditions and properly resolve regions where we expect instabilities to grow. We find that mass is channeled to the stellar system via gravitational and Rayleigh-Taylor (RT) instabilities, in agreement with previous results using stars capable of moving, but in disagreement with methods where the star is held fixed or with simulations that do not adequately resolve the development of RT instabilities. For laminar initial conditions, proper treatment of the direct radiation field produces later onset of instability, but does not suppress it entirely provided the edges of radiation-dominated bubbles are adequately resolved. Instabilities arise immediately for turbulent pre-stellar cores because the initial turbulence seeds the instabilities. Our results suggest that RT features are significant and should be present around accreting massive stars throughout their formation.

description: На основе значений удельной плотности проблемной ситуации можно ранжировать различные проблемные ситуации и поставленные задачи. Чем выше удельная плотность проблемы, тем более актуальной может быть рассматриваемая проблема и более перспективной ее решение. Такой подход значительно упрощает процесс выбора действительно актуальных для организации задач. В статье приведен алгоритм проведения анализа, а также показаны практические примеры этого вида анализа для постановки задач. Плотность проблемы это численный показатель проблемной ситуации, показывающий удельное значение параметра, характеризующего рассматриваемую проблему.
G 68-34: A Double-Lined M-Dwarf Eclipsing Binary in a Hierarchical Triple System

description: Using high-resolution spectra from the Tillinghast Reflector Echelle Spectrograph (TRES) and photometry from sector 56 of the Transiting Exoplanet Survey Satellite (TESS), we report that the nearby M dwarf G 68-34 is a double-lined eclipsing binary. The pair is spin-orbit synchronized with a period of 0.655 days. The light curve shows significant spot modulation with a larger photometric amplitude than that of the grazing eclipses. We perform a joint fit to the spectroscopic and photometric data, obtaining masses of $0.3280\pm 0.0034$M$_\odot$ and $0.3207\pm 0.0036$M$_\odot$ and radii of $0.345\pm 0.014$R$_\odot$ and $0.342\pm 0.014$R$_\odot$ after marginalizing over unknowns in the starspot distribution. This system adds to the small but growing population of fully convective M dwarfs with precisely measured masses and radii that can be used to test models of stellar structure. The pair also has a white dwarf primary at 9" separation, with the system known to be older than 5 Gyr from the white-dwarf cooling age. The binarity of G 68-34 confirms our hypothesis from Pass et al. (2022): in that work, we noted that G 68-34 was both rapidly rotating and old, highly unusual given our understanding of the spindown of M dwarfs, and that a close binary companion may be responsible.

description: Рассмотрен Жизненный цикл инновационного ТРИЗ-проекта, представляющий собой «воронку», состоящую из четырёх последовательных типов проектов: поискового, верификационного, собственно, инновационного и проекта внедрения. В поисковых проектах выполняется поиск идей, оценка их потенциальной экономической эффективности, влияния на бизнес, технической реализуемости (выявляются и разрешаются противоречия), наличия рынка и потенциальной пригодности для создания инноваций. Вырабатываются концептуальные направления. Далее осуществляется выработка концепций и их бенчмаркинг. На верификационных проектах осуществляется фактическая проверка реализуемости технических решений в рамках, предложенных на предыдущей стадии лидирующих концепций, выявляются вторичные задачи и вырабатываются их решения, проводится уточнение экономических оценок, оценки рыночных перспектив, определяются потенциальные Заказчики. В результате выявляются лидирующие верифицированные концепции, наиболее пригодные для создания инноваций. В инновационном проекте верифицированные концепции доводятся до создания продукта и технологии, и на их основе разрабатывается модель нового бизнеса (либо существенно модифицируется уже имеющийся). И наконец в проекте внедрения осуществляется воплощение разработанных инноваций в реальном бизнесе. Описана этапность и стадийность типов проектов, установлены типовые вехи для этапов и стадий. Предложена двухуровневая схема верификации. Описаны также базовые принципы управления портфелем инновационных ТРИЗ-проектов.
Dynamical theory of single photon transport in a one-dimensional waveguide coupled to identical and non-identical emitters

description: We develop a general dynamical theory for studying a single photon transport in a one-dimensional (1D) waveguide coupled to multiple emitters which can be either identical or non-identical. In this theory, both the effects of the waveguide and non-waveguide vacuum modes are included. This theory enables us to investigate the propagation of an emitter excitation or an arbitrary single photon pulse along an array of emitters coupled to a 1D waveguide. The dipole-dipole interaction induced by the non-waveguide modes, which is usually neglected in the literatures, can significantly modify the dynamics of the emitter system as well as the characteristics of output field if the emitter separation is much smaller than the resonance wavelength. Non-identical emitters can also strongly couple to each other if their energy difference is smaller than or of the order of the dipole-dipole energy shift. Interestingly, if their energy difference is close but non-zero, a very narrow transparency window around the resonance frequency can appear which does not occur for identical emitters. This phenomenon may find important applications in quantum waveguide devices such as optical switch and ultra narrow single photon frequency comb generator.
