description: Despite the value of VR (Virtual Reality) for educational purposes, the instructional power of VR in Biology Laboratory education remains under-explored. Laboratory lectures can be challenging due to students' low motivation to learn abstract scientific concepts and low retention rate. Therefore, we designed a VR-based lecture on fermentation and compared its effectiveness with lectures using PowerPoint slides and a desktop application. Grounded in the theory of distributed cognition and motivational theories, our study examined how learning happens in each condition from students' learning outcomes, behaviors, and perceptions. Our result indicates that VR facilitates students' long-term retention to learn by cultivating their longer visual attention and fostering a higher sense of immersion, though students' short-term retention remains the same across all conditions. This study extends current research on VR studies by identifying the characteristics of each teaching artifact and providing design implications for integrating VR technology into higher education.

description: We study fluctuating tilt Brownian ratchets based on fractional subdiffusion in sticky viscoelastic media characterized by a power law memory kernel. Unlike the normal diffusion case the rectification effect vanishes in the adiabatically slow modulation limit and optimizes in a driving frequency range. It is shown also that anomalous rectification effect is maximal (stochastic resonance effect) at optimal temperature and can exhibit a surprisingly good quality. Moreover, subdiffusive current can flow in the counter-intuitive direction upon a change of temperature or driving frequency. The dependence of anomalous transport on load exhibits a remarkably simple universality.

description: The Herschel survey, H-ATLAS, with its large areal coverage, has recently discovered a number of bright, strongly lensed high-z submillimeter galaxies. The strong magnification makes it possible to study molecular species other than CO, which are otherwise difficult to observe in high-z galaxies. Among the lensed galaxies already identified by H-ATLAS, the source J090302.9-014127B (SDP.17b) at z = 2.305 is remarkable due to its excitation conditions and a tentative detection of the H2O 202-111 emission line (Lupu et al. 2010). We report observations of this line in SDP.17b using the IRAM interferometer equipped with its new 277- 371GHz receivers. The H2O line is detected at a redshift of z = 2.3049+/-0.0006, with a flux of 7.8+/-0.5 Jy km s-1 and a FWHM of 250+/-60 km s-1. The new flux is 2.4 times weaker than the previous tentative detection, although both remain marginally consistent within 1.6-sigma. The intrinsic line luminosity and ratio of H2O(202-111)/CO8-7 seem comparable with those of the nearby starburst/enshrouded-AGN Mrk 231, suggesting that SDP.17b could also host a luminous AGN. The detection of a strong H2O 202-111 line in SDP.17b implies an efficient excitation mechanism of the water levels that must occur in very dense and warm interstellar gas.

Eliminating the long-running process : separating code and state
Creators: name: Colp, Patrick
Publisher: name: University of British Columbia
Year: 2010

description: Many critical services are necessarily long-running. However, this creates a large temporal surface that is an alluring target for attackers, both in terms of the increased opportunity to find an exploit and the length of time a service is owned once exploited. While in some instances it may be possible to perform periodic restarts to reduce the window of exploitation and return a service to its fresh, unexploited operational status, this carries with it a high cost. The more often it is restarted, the larger the unavailability due to reinitialisation of the service. Furthermore, it must recover its persistent state, which is not always possible. In order to protect these services, we propose a form of virtual machine disaggregation which partitions a service into two parts: code (logic) and state (data). Each lives in its own virtual machine, with communication performed over a narrow, well defined interface on which policy can be externally enforced to ensure correctness. This separation enables a service to be continually restarted by rolling back only the code virtual machine to a snapshotted known good state, which can be measured and attested. This prevents exploits from persisting while still maintaining good performance.

description: This paper investigates the energy savings that near-subthreshold processors can obtain in edge AI applications and proposes strategies to improve them while maintaining the accuracy of the application. The selected processors deploy adaptive voltage scaling techniques in which the frequency and voltage levels of the processor core are determined at the run-time. In these systems, embedded RAM and flash memory size is typically limited to less than 1 megabyte to save power. This limited memory imposes restrictions on the complexity of the neural networks model that can be mapped to these devices and the required trade-offs between accuracy and battery life. To address these issues, we propose and evaluate alternative 'big-little' neural network strategies to improve battery life while maintaining prediction accuracy. The strategies are applied to a human activity recognition application selected as a demonstrator that shows that compared to the original network, the best configurations obtain an energy reduction measured at 80% while maintaining the original level of inference accuracy.

description: We review numerous arguments for primordial black holes (PBHs) based on observational evidence from a variety of lensing, dynamical, accretion and gravitational-wave effects. This represents a shift from the usual emphasis on PBH constraints and provides what we term a positivist perspective. Microlensing observations of stars and quasars suggest that PBHs of around $1\,M_{\odot}$ could provide much of the dark matter in galactic halos, this being allowed by the Large Magellanic Cloud microlensing observations if the PBHs have an extended mass function. More generally, providing the mass and dark matter fraction of the PBHs is large enough, the associated Poisson fluctuations could generate the first bound objects at a much earlier epoch than in the standard cosmological scenario. This simultaneously explains the recent detection of high-redshift dwarf galaxies, puzzling correlations of the source-subtracted infrared and X-ray cosmic backgrounds, the size and the mass-to-light ratios of ultra-faint-dwarf galaxies, the dynamical heating of the Galactic disk, and the binary coalescences observed by LIGO/Virgo/KAGRA in a mass range not usually associated with stellar remnants. Even if PBHs provide only a small fraction of the dark matter, they could explain various other observational conundra, and sufficiently large ones could seed the supermassive black holes in galactic nuclei or even early galaxies themselves. We argue that PBHs would naturally have formed around the electroweak, quantum chromodynamics and electron-positron annihilation epochs, when the sound-speed inevitably dips. This leads to an extended PBH mass function with a number of distinct bumps, the most prominent one being at around $1\,M_{\odot}$, and this would allow PBHs to explain many of the observations in a unified way.

description: Coding has various fields and areas of focus. It is almost practically impossible for an individual to boss all the fields. A programmer can have sizeable knowledge of all the fields, but should still end up being an expert and maintain major focus in one area. It is a giant step towards the making of a successful personal brand for a software developer to maintain a high and unique level of expertise in his/her area of major focus. This gives potential clients a trust and reliability settlement when patronizing the developer for service needed in the chosen area. Those who specialize are generally preferred over the ‘multipurpose’ personnel.

description: This paper presents a study of the finite axiomatizability of transitive logics of finite depth and finite weak width. We prove the finite axiomatizability of each transitive logic of finite depth and of weak width $1$ that is characterized by rooted transitive frames in which all antichains contain at most $n$ irreflexive points. As a negative result, we show that there are non-finitely-axiomatizable transitive logics of depth $n$ and of weak width $k$ for each $n\geqslant3$ and $k\geqslant2$.

description: When a $γ$-ray interacts in a semiconductor detector, the resulting electron-hole charge clouds drift towards their respective electrodes for signal collection. These charge clouds will expand over time due to both thermal diffusion and mutual electrostatic repulsion. Solutions to the resulting charge profiles are well understood for the limiting cases accounting for only diffusion and only repulsion, but the general solution including both effects can only be solved numerically. Previous attempts to model these effects have taken into account the broadening of the charge profile due to both effects, but have simplified the shape of the profile by assuming Gaussian distributions. However, the detailed charge profile can have important impacts on charge sharing in multi-electrode strip detectors. In this work, we derive an analytical approximation to the general solution, including both diffusion and repulsion, that closely replicates both the width and the detailed shape of the charge profiles. This analytical solution simplifies the modeling of charge clouds in semiconductor strip detectors.

description: ABSTRACT An empirical study on the rules, design and acceptance of an ancient board
 game ("Pente Grammai"), starting from the reconstruction and redesign of the
 game. Tests at Viennese elementary schools will contribute to answering the
 question of what (for whom) constitutes a "good game". Based on the game theoretical approaches of Roger Caillois, the project "Locus Ludi" - a cooperation between the Institute of Classical Archaeology at the University of
 Fribourg and the Department of Cultural Studies at the University of Applied Arts
 Vienna - poses the question of the criteria of "good (board)games". The study of Pente Grammai is guided by several questions that use the game as culturalhistorical
 material: - Can games be used as a cultural-historical source or to what extent can
 games be reconstructed in their rules from fragmentary sources?
 (Cultural-historical aspect) - What influence do different narratives and rule systems have on the success
 of a game, i.e. on the preference for a particular game variant?
 (narratological-ludical aspect) - Are there age-, gender- and stratum-specific differences in the preference of
 game variants?
 (cultural-sociological aspect) Based on findings and theses from archaeological research and ancient sources, the
 "Five Line Game" (Pente Grammai) a) was first reconstructed in its possible rules in cooperation with
 archaeologists and game researchers, b) redesigned in several versions (two different rule systems [beating/nonbeating]
 and two narratives [travel/hunting] were created) and c) tested in an empirical survey with a population of 184 children aged six to
 eleven years from different social milieus, as well as a comparison group of 25
 adults, in order to determine the preferences of the gamblers. The surveys provide information about the preferences of rules and narratives in
 games and the relationship between the two. For the first time, differences in
 preferences and their argumentation according to gender, age and social context
 could be identified. Some assumptions were confirmed, but others turned out to be
 prejudices in the sense of typical gender-specific and social stereotypes in the
 concrete survey. Finally, the study shows by means of the reconstruction, redesign
 and testing of an ancient board game that games are still an underestimated subject
 of cultural and social science research.

title: Influence of Quenching and Subsequent Annealing on the Conductivity and Electromechanical Properties of Na₁/₂Bi₁/₂TiO₃-BaTiO₃
Creators: name: Kodumudi Venkataraman, Lalitha
Publisher: name: MDPI
Year: 2023

description: Na₁/₂Bi₁/₂TiO₃-based materials have gained considerable attention for their potential to exhibit giant strain, very-high ionic conductivity comparable to yttria stabilized zirconia or high mechanical quality factor for use in high power ultrasonics. In recent times, quenching Na₁/₂Bi₁/₂TiO₃-based compositions have been demonstrated to enhance the thermal depolarization temperature, thus increasing the operational temperature limit of these materials in application. This work investigates the role of quenching-induced changes in the defect chemistry on the dielectric, ferroelectric and piezoelectric properties of quenched Na₁/₂Bi₁/₂TiO₃-BaTiO₃.The quenched samples indeed demonstrate an increase in the bulk conductivity. Nevertheless, while subsequent annealing of the quenched samples in air/oxygen atmosphere reverts back the depolarization behaviour to that of a furnace cooled specimen, the bulk conductivity remains majorly unaltered. This implies a weak correlation between the defect chemistry and enhanced thermal stability of the piezoelectric properties and hints towards other mechanisms at play. The minor role of oxygen vacancies is further reinforced by the negligible (10–15%) changes in the mechanical quality factor and hysteresis loss.

Forschungseinrichtungen treten zunehmend als Träger und Dienstleister für wissenschaftliche Publikationen in Erscheinung. Mit dem Internet und freier Software ist es heute möglich, ohne Einbeziehung von kommerziellen Anbietern Open-Access-Zeitschriften professionell herauszugeben. Dafür wird Basis-Know-how benötigt, welches hier in Form einer Checkliste bereitgestellt wird. In den letzten Jahren wurden an vielen wissenschaftlichen Institutionen in Österreich auch Beratungsangebote aufgebaut, die ergänzend zur Checkliste in Anspruch genommen werden können. Mitunter stehen dort sogar technische Publikationsinfrastrukturen bereit, die es den ZeitschriftenbetreiberInnen erlauben, sich auf Inhalt und Qualität des Journals zu konzentrieren. Gleichzeitig kann diese Checkliste als Begleitmaterial für Beratungen dienen, die forschungsunterstützende Serviceeinrichtungen (Bibliotheken, Universitätsverlage …) für HerausgeberInnen anbieten.

About this checklist

Research institutions increasingly act as supporting organisations and service providers for scholarly publications. Professional publishing of Open Access journals is possible without recourse to commercial suppliers by means of the internet and free software. This requires basic know how which is presented in form of this checklist. Over the past few years many research institutions have begun to establish advisory services that may be consulted in addition to this checklist. Occasionally they even offer technical infrastructures that enable editors to focus on content and quality of their journals. At the same time this checklist may act as supplementary material for consulting sessions that research services (libraries, university publishers …) offer to editors.

description: There are (at least) two surfaces of particular interest in eternal de Sitter space. One is the timelike hypersurface constituting the lab wall of a static patch observer and the other is the future boundary of global de Sitter space. We study both linear and non-linear deformations of four-dimensional de Sitter space which obey the Einstein equation. Our deformations leave the induced conformal metric and trace of the extrinsic curvature unchanged for a fixed hypersurface. This hypersurface is either timelike within the static patch or spacelike in the future diamond. We require the deformations to be regular at the future horizon of the static patch observer. For linearized perturbations in the future diamond, this corresponds to imposing incoming flux solely from the future horizon of a single static patch observer. When the slices are arbitrarily close to the cosmological horizon, the finite deformations are characterized by solutions to the incompressible Navier-Stokes equation for both spacelike and timelike hypersurfaces. We then study, at the level of linearized gravity, the change in the discrete dispersion relation as we push the timelike hypersurface toward the worldline of the static patch. Finally, we study the spectrum of linearized solutions as the spacelike slices are pushed to future infinity and relate our calculations to analogous ones in the context of massless topological black holes in AdS$_4$.

On-chip surfing interconnect
Creators: name: Yang, Suwen
Publisher: name: University of British Columbia
Year: 2010

description: With growing chip sizes and operating frequencies, on-chip global interconnect has become a critical bottleneck for CMOS technology. With processes scaling into deep submicron scales, the gap between gate delay and global-interconnect delay increases with each technology generation. Bandwidth is also important for on-chip interconnect and is limited by skew and jitter. Due to temperature variation, crosstalk noise, power supply variation and parameter variation, timing variation increases with the length of global interconnect lines. Jitter and skew in the transmitter and receiver's clocks add timing variation to on-chip interconnect communication. Repeaters in a buffering technique amplify clock jitter and drop pulses due to intersymbol interference. Latches can be inserted in place of some of the buffers to control the timing variation. However, these latches increase latency and power consumption. In 2002, a novel circuit technique called ``surfing'' was proposed to bound the timing uncertainty in wave pipelines~\cite{Winters02}. This thesis extends the application of surfing to on-chip interconnects and introduces surfing RC interconnect and surfing LC interconnect techniques. For RC interconnects, we present a jitter attenuating buffer. This buffer uses inverters with variable output strength to implement a simple, low-gain DLL. Chains of these surfing buffers attenuate jitter making them well suited for source-synchronous interconnect. Furthermore, our chains can be used to reliably transmit handshaking signals and support sliding-window protocols to improve the throughput of asynchronous communication. We use distributed varactors to dynamically vary the latency of LC interconnects and thus effect surfing. Different from RC signaling, signals on LC interconnect propagate at nearly the speed-of-light. The varactors not only modulate the line latency, but also sharpen the edges of signals. We present both a full-swing and a low-swing LC interconnect designs. In both interconnects, the jitter and skew are attenuated along the line due to the surfing effect. In the low swing interconnect, the surfing effect also helps to reshape the pulses to increase the eye height. To demonstrate these techniques in real silicon, we designed, fabricated and tested a chip. The testing results show that surfing LC interconnects are promising for deep submicron technology.

description: Comments within source code are essential for developers to comprehend the code's purpose and ensure its correct usage. However, as codebases evolve, maintaining an accurate alignment between the comments and the code becomes increasingly challenging. Recognizing the growing interest in automated solutions for detecting and correcting differences between code and its accompanying comments, current methods rely primarily on heuristic rules. In contrast, this paper presents DocChecker, a tool powered by deep learning. DocChecker is adept at identifying inconsistencies between code and comments, and it can also generate synthetic comments. This capability enables the tool to detect and correct instances where comments do not accurately reflect their corresponding code segments. We demonstrate the effectiveness of DocChecker using the Just-In-Time and CodeXGlue datasets in different settings. Particularly, DocChecker achieves a new State-of-the-art result of 72.3% accuracy on the Inconsistency Code-Comment Detection (ICCD) task and 33.64 BLEU-4 on the code summarization task against other Large Language Models (LLMs), even surpassing GPT 3.5 and CodeLlama.
 DocChecker is accessible for use and evaluation. It can be found on our GitHub https://github.com/FSoft-AI4Code/DocChecker and as an Online Tool http://4.193.50.237:5000/. For a more comprehensive understanding of its functionality, a demonstration video is available on YouTube https://youtu.be/FqnPmd531xw.

description: We present an updated view of the rotation-activity-age relation for (old) field M dwarfs based on K2 rotation periods and flares, archival X-ray and UV data, and dedicated Chandra and XMM-Newton observations.

The rotation-activity-age relation can be used as a proxy for magnetic fields -- which are difficult to measure in M dwarfs -- and is, therefore, key to studies of (i) the predicted dynamo transition at the fully convective boundary (SpT~M3), (ii) differences in angular momentum loss through magnetized winds with respect to solar-type stars, and (iii) the evaporation of planet atmospheres, especially relevant for M dwarfs because of the small separation of their planets' habitable zones where they are strongly exposed to the stellar high-energy emission.

We use a two-fold approach to obtain tight observational constraints: (1) In our study of the activity-rotation relation of nearby, proper-motion selected M dwarfs using photometric time-series from the K2 mission combined with X-ray and UV data we find strong evidence for an abrupt change of optical photometric activity (flares, rotation cycle amplitude and residual variability) at P_rot~10d, and an unexpectedly steep decline of X-ray activity in the unsaturated regime of slow rotators. (2) The age-activity relation is investigated through deep X-ray observations of a sample of M dwarfs in wide binaries with white dwarfs. Here the white dwarf serves as a chronometer for the age of the M dwarf.

Our results provide important input for accurate angular momentum evolution models and planet atmosphere escape calculations for M dwarfs.

We obtain the viscosity-to-entropy ratio and the second order transport coefficients of the dual fluid of noncritical gravity to all orders in the coupling of higher derivative terms. We also compute the holographic entanglement entropy in the dual CFT of noncritical gravity. All these results confirm the nonlinear equivalence between noncritical gravity and Einstein gravity at the classical level.

We show that the strength and sign of this dependence greatly alter synchronization and yield qualitatively different phase diagrams. The Ott-Antonsen ansatz allows us to obtain analytical results for a specific family of joint distributions. We also derive, using linear stability analysis, general formulae for the stability border of incoherence.

description: We study the influence of the polarization angle of linear radiation on the radiation-induced magnetoresistance oscillations in two-dimensional electron systems and examine the polarization immunity on the temperature and quality of the sample. We have applied the radiation-driven electron orbits model obtaining that the magnetoresistance is affected by the orientation of the electric field of linearly polarized radiation when dealing with high quality samples and low temperatures. Yet, for lower quality samples and higher temperature, we recover polarization immunity in the radiation driven magnetoresistance oscillations. This could be of interest for future photoelectronics in high quality mesoscopic devices. VC 2012 American Institute of Physics

description: We solve a fractional diffusion equation using a piecewise-constant, discontinuous Galerkin method in time combined with a continuous, piecewise-linear finite element method in space. If there are $N$ time levels and $M$ spatial degrees of freedom, then a direct implementation of this method requires $O(N^2M)$ operations and $O(NM)$ active memory locations, owing to the presence of a memory term: at each time step, the discrete evolution equation involves a sum over \emph{all} previous time levels. We show how the computational cost can be reduced to $O(MN\log N)$ operations and $O(M\log N)$ active memory locations.

description: In this letter we consider the dynamic behaviors of spin-orbit coupled Bose condensates realized in recent experiments. We show that there exists an interaction induced ac Hall response which is absent in a non-interacting system. This condensate has two distinct equilibrium phases known as the plane wave phase and the stripe phase. In the plane wave phase, we show that an ac longitudinal current will induce an ac radial current in the transverse direction, and vice versa, as a cooperation effect of spin-velocity locking and spin-dependent interaction. In the stripe phase, we show that the dominant longitudinal response to a transverse radial current is sliding of the density stripe, because it is the low-lying excitation mode originated from spontaneous spatial translational symmetry breaking in this phase.

description: Interruptions are a common part of daily life, especially in busy urban areas where pedestrians are often delayed at traffic lights or waiting for entrances or exits to open. The topic of this contribution is to examine social interactions and behavioral reactions resulting from interruptions. These states can have both physiological and psychological/social components, such as changes in heart rate and feelings of impatience or boredom, as well as changes in motivation levels. The study specifically examines interruptions in pedestrian crowds using a high/low motivation dichotomy within an experimental setting resembling a concert entrance. It was hypothesized that highly motivated crowds would experience high-arousal impatience state when interrupted, while low-motivated crowds would experience low-arousal boredom. Additionally, the study hypothesized that interruptions would decrease motivation levels. To test these hypotheses, 301 participants (100 per run) walked through a bottleneck resembling a concert entrance and completed questionnaires on impatience, boredom, and motivation. 60 participants (20 per run) were equipped with portable heart rate devices. Furthermore, all participants were filmed with ceiling-mounted cameras. Trajectories of participants were extracted from the footage (with the software PeTrack) to calculate crowd density (person/m2), and qualitative observations were made based on the video footage. The results supported the hypotheses, indicating that high motivation leads to higher levels of impatience, while low motivation causes boredom. Interruptions also decreased motivation, as seen in the questionnaire data (and hinted in the heart rate data) and resulted in a lower crowd density after the interruption. Overall, the study provides valuable insights into how interruptions affect social interactions and behavioral reactions in pedestrian crowds.

description: This paper presents a methodology of controlling the resonance energy exchange in mechanical system consisting of two weakly coupled magnetic pendulums interacting with the magnetic field generated by coils placed underneath. It is shown that properly guided magnetic fields can effectively change mechanical potentials in a way that the energy flow between the oscillators takes the desired direction. Studies were considered by using a specific set of descriptive functions characterizing the total excitation level, its distribution between the pendulums, and the phase shift. The developed control strategies are based on the observation that, in the case of antiphase oscillation, the energy is moving from the pendulum subjected to the repelling magnetic field, to the oscillator under the attracting field. In contrast, during the inphase oscillations, the energy flow is reversed. Therefore, closed-loop controller requires only the information about phase shift, which is easily estimated from dynamic state signals through the coherency index. Advantage of suggested control strategy is that the temporal rate of inputs is dictated by the speed of beating, which is relatively slow compared to the carrying oscillations.

description: Stochastic thermodynamics as reviewed here systematically provides a framework for extending the notions of classical thermodynamics like work, heat and entropy production to the level of individual trajectories of well-defined non-equilibrium ensembles. It applies whenever a non-equilibrium process is still coupled to one (or several) heat bath(s) of constant temperature. Paradigmatic systems are single colloidal particles in time-dependent laser traps, polymers in external flow, enzymes and molecular motors in single molecule assays, small biochemical networks and thermoelectric devices involving single electron transport. For such systems, a first-law like energy balance can be identified along fluctuating trajectories. Various integral and detailed fluctuation theorems, which are derived here in a unifying approach from one master theorem, constrain the probability distributions for work, heat and entropy production depending on the nature of the system and the choice of non-equilibrium conditions. For non-equilibrium steady states, particularly strong results hold like a generalized fluctuation-dissipation theorem involving entropy production. Ramifications and applications of these concepts include optimal driving between specified states in finite time, the role of measurement-based feedback processes and the relation between dissipation and irreversibility. Efficiency and, in particular, efficiency at maximum power, can be discussed systematically beyond the linear response regime for two classes of molecular machines, isothermal ones like molecular motors, and heat engines like thermoelectric devices, using a common framework based on a cycle decomposition of entropy production.

description: Early diagnosis is a major aspect for treating any disease and Machine Learning (ML) plays a vital role in speeding up the diagnosis process and increase the efficiency of existing treatment strategies. A short yet effective review of the curre in diagnosing Alzheimer’s with the help of Machine Learning has been done in this pape . This nt trends This review will help in our future work or other contributors working on Drug Repurposing Techniques. In this review, we have found that the Models used in various studies such as ANN, SVM, DNN, CNN etc have achieved accuracy greater than 90% whic work. Upon analysis we have found that various studies have used MRI images for classifying Alzheimer’s. With advancements in computer aided systems, production of quality information from the image processing techniques has int fi roduced various challenges and these challenges are tried to resolve through ML. As the number of studies focusing on the use of ML has increased, the ef ciency of the diagnostic systems has also increased and are helping the medical community.
A mass transfer origin for blue stragglers in NGC 188 as revealed by half-solar-mass companions

description: In open star clusters, where all members formed at about the same time, blue straggler stars are typically observed to be brighter and bluer than hydrogen-burning main-sequence stars, and therefore should already have evolved into giant stars and stellar remnants. Correlations between blue straggler frequency and cluster binary fraction, core mass, and radial position suggest that mass transfer or mergers in binary stars dominates the production of blue stragglers in open clusters. Analytic models, detailed observations, and sophisticated N-body simulations, however, argue in favor of stellar collisions. Here we report that the blue stragglers in long-period binaries in the old (7 Gyr) open cluster NGC 188 have companions with masses of about half a solar mass, with a surprisingly narrow mass distribution. This conclusively rules out a collisional origin, as the collision hypothesis predicts a companion-mass distribution with significantly higher masses. Mergers in hierarchical triple stars are marginally permitted by the data, but the observations do not favor this hypothesis. The data are closely consistent with a mass transfer origin for the long-period blue straggler binaries in NGC 188, in which the companions would be white dwarfs of about half a solar mass.
