description: The discovery of novel phases of matter is at the core of modern physics. In quantum materials, subtle variations in atomic-scale interactions can induce dramatic changes in macroscopic properties and drive phase transitions. Despite their importance, the mesoscale processes underpinning phase transitions often remain elusive because of the vast differences in timescales between atomic and electronic changes and thermodynamic transformations. Here, we photoinduce and directly observe with x-ray scattering an ultrafast enhancement of the structural long-range order in the archetypal Mott system V2O3. Despite the ultrafast change in crystal symmetry, the change of unit cell volume occurs an order of magnitude slower and coincides with the insulator-to-metal transition. The decoupling between the two structural responses in the time domain highlights the existence of a transient photoinduced precursor phase, which is distinct from the two structural phases present in equilibrium. X-ray nanoscopy reveals that acoustic phonons trapped in nanoscale blocks govern the dynamics of the ultrafast transition into the precursor phase, while nucleation and growth of metallic domains dictate the duration of the slower transition into the metallic phase. The enhancement of the long-range order before completion of the electronic transition demonstrates the critical role the non-equilibrium structural phases play during electronic phase transitions in correlated electrons systems.

description: The forestomach of the ruminant animal is a highly effective energy-producing factory which can utilize a wide variety of feedstuffs. Many complex interactions occur within the forestomachs to digest, mix, and absorb nutrients from feed. Slight alterations in forestomach balance can lead to severe alterations in function, such as hypomotility, hypermotility, bloat, acidosis, or putrefaction. It is essential to understand and be able to treat and prevent forestomach disease in cattle. Some of the most common diseases are reviewed here, possible treatments given, and the use of motility-enhancing drugs is briefly discussed.

description: Decoding someone's facial expressions provides insights into his or her emotional experience. Recently, Automatic Facial Coding (AFC) software has been developed to provide measurements of emotional facial expressions. Previous studies provided first evidence for the sensitivity of such systems to detect facial responses in study participants. In the present experiment, we set out to generalise these results to affective responses as they can occur in variable social interactions. Thus, we presented facial expressions (happy, neutral, angry) and instructed participants (N = 64) to either actively mimic, to look at them passively (n = 21), or to inhibit their own facial reaction (n = 22). A video stream for AFC and an electromyogram (EMG) of the zygomaticus and corrugator muscles were registered continuously. In the mimicking condition, both AFC and EMG differentiated well between facial expressions in response to the different emotional pictures. In the passive viewing and in the inhibition condition AFC did not detect changes in facial expressions whereas EMG was still highly sensitive. Although only EMG is sensitive when participants intend to conceal their facial reactions, these data extend previous findings that Automatic Facial Coding is a promising tool for the detection of intense facial reaction.

description: We have characterized a semiconductor amplifier laser system which provides up to 200mW output after a single-mode optical fiber at 780nm wavelength. The system is based on a tapered semiconductor gain element, which amplifies the output of a narrow-linewidth diode laser. Gain and saturation are discussed as a function of operating temperature and injection current. The spectral properties of the amplifier are investigated with a grating spectrometer. Amplified spontaneous emission (ASE) causes a spectral background with a width of 4nm FWHM. The ASE background was suppressed to below our detection limit by a proper choice of operating current and temperature, and by sending the light through a single-mode optical fiber. The final ASE spectral density was less than 0.1nW/MHz, i.e. less than 0.2 % of the optical power. Related to an optical transition linewidth of $Γ/2π=6$ MHz for rubidium, this gives a background suppression of better than -82dB. An indication of the beam quality is provided by the fiber coupling efficiency up to 59 %. The application of the amplifier system as a laser source for atom optical experiments is discussed.

description: A technique is described that permits the robust decomposition of the bulge and disk components of a sample of Seyfert galaxies, as well as a (control) sample of non-active galaxies matched to the Seyferts in the distributions of redshift, luminosity and morphological classification. The structural parameters of the host galaxies in both samples are measured. No statistically significant differences at greater than the 95% level are found in these parameters according to a K-S test. ``Companion galaxies'' --- defined as any galaxy within a projected separation of 200 h^{-1} kpc from the center of the host --- are identified and their basic properties measured. A comparison between the active and control samples in the distributions of apparent R magnitude, absolute R magnitude (assuming the ``companions'' are at the distance of the host), projected separation from the host, position angle relative to the host, magnitude difference between the companion and host, and strength of the tidal parameter, show no statistically significant differences. Similarly, no statistically significant differences are found between the control and active sample host galaxies in terms of light asymmetries --- bars, rings, isophotal twisting, etc. The implications for a model in which interactions and mergers are responsible for inciting activity in galactic nuclei are discussed briefly.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

The Association between forage particle size at initial feeding and the weigh-back and chewing activity in dairy cattle

description: A field trial was conducted at the University of Florida Dairy Research Unit (USA) to determine the relationship between initial coarse portion (ICP) particle size of a total mixed ration (TMR) and orts (weigh-back coarse portion, WBCP) of the same TMR. Additionally, the relationship between the ICP of a TMR and the proportion of cows chewing their cud 2.0 hours after feeding was determined. A random representative sample of TMR was taken from the feed bunk at initial feeding and 8 h later (weigh-back) every day from the same barn for 75 days. Samples were analysed for particle size content using a particle size evaluator. Proportion of the largest particles of the TMR was recorded. Additionally, the proportion of cows ruminating 2.0 hours after the morning feeding was recorded each day. Correlation and regression models between ICP and WBCP, and between ICP and the proportion of ruminating cows were calculated. The mean and standard deviation for ICP, WBCP and proportion of cows cud chewing were 14.2ñ6.6, 29.9ñ13.2 and 18.4ñ5.0%, respectively. The Pearson correlation coefficient between ICP and WBCP was 0.53, and the correlation coefficient between the proportion of cows chewing their cud and ICP in the TMR was 0.19. Initial coarse proportion was a predictor for WBCP (p<0.01), but was not a predictor of the proportion of cows ruminating 2 h after the morning feeding (p>0.05). These findings are suggestive of sorting of the TMR by the cows. Sorting was significantly higher (p<0.01) as the coarse proportion at the initial feeding increased, but this difference was likely of little biological significance.

Sudden death of three calves within two weeks of vaccination and castration
Creators: name: (Reynolds) Mills, Sarah M.
Publisher: name: The Bovine Practitioner
Year: 2002

description: Three male beef calves, 3-4 mo of age, died a few days after vaccination and castration. Because the pasture had been used several years without incident by the producer for calving, environmental causes were low on the differential diagnosis list. Because there was not an opportunity to examine the calves ante-mortem and necropsy findings were unremarkable, the practitioner relied on the producer?s description of clinical signs, then worked with the producer and pathologist to reach a definitive diagnosis of lead poisoning. The blood lead level in one calf that died was 4.3 ppm, and the kidney lead level was 101 ppm. Economic concerns were compounded due to potential exposure of a number of cows in the first trimester of pregnancy.

Non-Abelian gauge field theory in scale relativity

description: Gauge field theory is developed in the framework of scale relativity. In this theory, space-time is described as a non-differentiable continuum, which implies it is fractal, i.e., explicitly dependent on internal scale variables. Owing to the principle of relativity that has been extended to scales, these scale variables can themselves become functions of the space-time coordinates. Therefore, a coupling is expected between displacements in the fractal space-time and the transformations of these scale variables. In previous works, an Abelian gauge theory (electromagnetism) has been derived as a consequence of this coupling for global dilations and/or contractions. We consider here more general transformations of the scale variables by taking into account separate dilations for each of them, which yield non-Abelian gauge theories. We identify these transformations with the usual gauge transformations. The gauge fields naturally appear as a new geometric contribution to the total variation of the action involving these scale variables, while the gauge charges emerge as the generators of the scale transformation group. A generalized action is identified with the scale-relativistic invariant. The gauge charges are the conservative quantities, conjugates of the scale variables through the action, which find their origin in the symmetries of the ``scale-space''. We thus found in a geometric way and recover the expression for the covariant derivative of gauge theory. Adding the requirement that under the scale transformations the fermion multiplets and the boson fields transform such that the derived Lagrangian remains invariant, we obtain gauge theories as a consequence of scale symmetries issued from a geometric space-time description.

description: Recent all-sky surveys have led to the discovery of new types of transients. These include stars disrupted by the central supermassive black hole, and supernovae that are 10-100 times more energetic than typical ones. However, the nature of even more energetic transients that apparently occur in the innermost regions of their host galaxies is hotly debated. Here we report the discovery of the most energetic of these to date: PS1-10adi, with a total radiated energy of ~ 2.3 x 10^52 erg. The slow evolution of its light curve and persistently narrow spectral lines over ~3 yr are inconsistent with known types of recurring black hole variability. The observed properties imply powering by shock interaction between expanding material and large quantities of surrounding dense matter. Plausible sources of this expanding material are a star that has been tidally disrupted by the central black hole, or a supernova. Both could satisfy the energy budget. For the former, we would be forced to invoke a new and hitherto unseen variant of a tidally disrupted star, while a supernova origin relies principally on environmental effects resulting from its nuclear location. Remarkably, we also discovered that PS1-10adi is not an isolated case. We therefore surmise that this new population of transients has previously been overlooked due to incorrect association with underlying central black hole activity.

description: Selenium may affect a wider range of metabolic functions than only those associated with nutritional myodegeneration, but there is controversy regarding the type of problems that may be associated with suboptimal selenium status in cattle. An animal's nutritional requirement for selenium and vitamin E depends on age, physiological stage and species. In cattle, low selenium status becomes critical near calving when cows are more susceptible to intramammary infections, retained placenta, or infections in the neonate. Analysis of serum samples (n=204) submitted to the Iowa State University Veterinary Diagnostic Laboratory between January 2000 and July 2001, showed a mean (ñSD) serum selenium value of 68.4ñ17 ppb for adult Holstein cows in the Iowa and Wisconsin areas. Because cattle receiving higher levels of selenium and vitamin E than typically recommended may show improved immunocompetence, the levels found in this survey can be considered adequate for reproductive performance, but marginal for optimal resistance to mastitis pathogens or for adequate transfer of selenium to the suckling calf. This report also contradicts previous claims that selenium deficiency contributes to stillborn/weakborn calves. Studies relating selenium concentrations in blood and serum to common clinical conditions of cattle attributed to poor selenium status are reviewed; methods of supplementation are also addressed.

description: The large-scale computer simulation of a system of physical fields governed by partial differential equations requires some means of approximating the mathematical limit of continuity. For example, conservation laws are often treated with a `finite-volume' approach in which space is partitioned into a large number of small `cells,' with fluxes through cell faces providing an intuitive discretization modeled on the mathematical definition of the divergence operator. Here we describe and make available Fortran 2003 classes furnishing extensible object-oriented implementations of simple meshes and the evolution of generic conserved currents thereon, along with individual `unit test' programs and larger example problems demonstrating their use. These classes inaugurate the Mathematics division of our developing astrophysics simulation code GenASiS (General Astrophysical Simulation System), which will be expanded over time to include additional meshing options, mathematical operations, solver types, and solver variations appropriate for many multiphysics applications.

description: Theoretical treatments of strong-field physics have long relied on the numerical solution of the time-dependent Schrödinger equation. The most effective such treatments utilize a discrete spatial representation---a grid. Since most strong-field observables relate to the continuum portion of the wave function, the boundaries of the grid---which act as hard walls and thus cause reflection---can substantially impact the observables. Special care thus needs to be taken. While there exist a number of attempts to solve this problem---e.g., complex absorbing potentials and masking functions, exterior complex scaling, and coordinate scaling---none of them are completely satisfactory. The first of these is arguably the most popular, but it consumes a substantial fraction of the computing resources in any given calculation. Worse, this fraction grows with the dimensionality of the problem. And, no systematic way to design such a potential has been used in the strong-field community. In this work, we address these issues and find a much better solution. By comparing with previous widely used absorbing potentials, we find a factor of 3--4 reduction in the absorption range, given the same level of absorption over a specified energy interval.

description: Biological systems are among the most challenging subjects for theoretical physicists, as well as experimentalists or simulationists. Physical principles should have been both constraints and guide-lines for the evolution of living systems over billions of years. One generally aims at clarifying what physical principles, possibly new ones, are behind the phenomena of biological interest and at understanding how they work within the entire biological world. In the present talk we describe an example of such an effort. Since the discovery of `superprecipitation' by Szent-Gyorgyi's group in 1940's, it has been a long puzzle how an assemblage of actin filaments with random orientation can contract in the presence of the two-headed myosin molecules undergoing actin-activated ATP-hydrolysis reaction. It is widely accepted that during the contraction the two-headed myosin mediates the relative sliding of two actin filaments whose polarity directions are not parallel but rather anti-parallel. But this fact solely does not account for the shortening. We propose a dynamical model which, upon numerical simulation, exhibits the shortening of an bundle of the actin filaments which are initially dirstributed randomly both in space along a line and in polarity direction. In the course of shortening several clusters of actins appears along the bundle. The model also shows the sorting of the actin filaments according to their polarity in the late stage. These findings are in accordance with the recent experiment by Takiguchi.

description: We present a study of the nonmesonic weak decay (NMWD) of charmed hypernuclei using a relativistic formalism. We work within the framework of the independent particle shell model and employ a ($π$,$K$) one-meson-exchange model for the decay dynamics. We implement a fully relativistic treatment of nuclear recoil. Numerical results are obtained for the one-neutron-induced transition NMWD rates of the $_{Λ^{+}_{c}}^{12}$N. The effect of nuclear recoil is sizable and goes in the direction to decrease the nuclear decay rate. We found that the NMWD decay rate of $_{Λ^{+}_{c}}^{12}$N is of the same order of magnitude as the partial decay rate for the corresponding mesonic decay $Λ^+_c \rightarrow Λ+ π^+$, suggesting the feasibility of experimental detection of such heavy-flavor nuclear processes.

description: It is well-documented that face perception – including facial expression and identity recognition ability – declines with age. To date, however, it is not yet well understood whether this age-related decline reflects face-specific effects, or instead can be accounted for by well-known declines in general intelligence. We examined this issue using a relatively large, healthy, age-diverse (18-88 years) sample (N = 595) who were assessed on well-established measures of face perception and general intelligence. Replicating previous work, we observed that facial expression recognition, facial identity recognition, and general intelligence all showed declines with age. Of importance, the age-related decline of expression and identity recognition was present even when the effects of general intelligence were statistically controlled. Moreover, facial expression and identity ability each showed significant unique associations with age. These results indicate that face perception ability becomes poorer as we age, and that this decline is to some extent relatively focal in nature. Results are in line with a hierarchical structure of face perception ability, and suggest that age appears to have independent effects on the general and specific face processing levels within this structure.

description: Creating safe Transportation Cyber-Physical Systems (CPSs) presents new challenges as autonomous operation is attempted in unconstrained operational environments. The extremely high safety level required of such systems (perhaps one critical failure per billion operating hours) means that validation approaches will need to consider not only normal operation, but also operation with system faults and in exceptional environments. Additional challenges will need to be overcome in the areas of rigorously defining safety requirements, trusting the safety of multi-vendor distributed system components, tolerating environmental uncertainty, providing a realistic role for human oversight, and ensuring sufficiently rigorous validation of autonomy technology.

description: A high-confidence map of the direct, functional targets each transcription factor (TF) requires convergent evidence from independent sources. Two significant sources of evidence are TF binding locations and the transcriptional response to direct TF perturbations. If most genes whose promoters are bound by a TF responded to a perturbation of the TF, that would provide the convergent evidence we need. We show, using large ChIP and perturbation-response data sets from yeast and human, that standard experimental and analytic techniques fail to provide that convergent evidence, consistent with previous findings based on smaller, older data sets. Specifically, most promoter-binding events do not lead to a transcriptional responses. A natural fallback would be to take the small fraction of bound genes that do respond as high-confidence, direct targets, an approach we call the intersection algorithm. We derive a new lower bound on the expected false discovery rate (FDR) of the intersection algorithm, as a function of its sensitivity. This shows that it does not perform well when many of the bound genes are not responsive and many of the responsive genes are not bound. Using standard experimental and analytic methods, data on most TFs are not acceptable, by which we mean that either the intersection algorithm cannot achieve a 20% FDR with 80% sensitivity or the bound-responsive intersection is no larger than would be expected for random gene sets.

We then introduce a simple, new method for setting significance thresholds on binding and perturbation response data that we call dual threshold optimization (DTO). DTO substantially increases the number of TFs for which the data are convergent. We also analyze substantial new binding location and perturbation response data sets, generated using newer experimental methods: ChIP-exo and transposon calling cards for binding and dynamic TF induction for perturbation response. These methods that show much better convergence than standard methods. Finally, we demonstrate that processing the perturbation data through expression-based network inference algorithms that do not use binding data improves convergence. Taken together, our findings suggest that we are on the verge of a new era in which binding location data and perturbation response data will converge on a high-confidence map of direct TF targets.

description: Magnetic reconnection is thought to drive a wide variety of dynamic phenomena in the solar atmosphere. Yet the detailed physical mechanisms driving reconnection are difficult to discern in the remote sensing observations that are used to study the solar atmosphere. In this paper we exploit the high-resolution instruments Interface Region Imaging Spectrograph (IRIS) and the new CHROMIS Fabry-Perot instrument at the Swedish 1-m Solar Telescope (SST) to identify the intermittency of magnetic reconnection and its association with the formation of plasmoids in so-called UV bursts in the low solar atmosphere. The Si IV 1403A UV burst spectra from the transition region show evidence of highly broadened line profiles with often non-Gaussian and triangular shapes, in addition to signatures of bidirectional flows. Such profiles had previously been linked, in idealized numerical simulations, to magnetic reconnection driven by the plasmoid instability. Simultaneous CHROMIS images in the chromospheric Ca II K 3934A line now provide compelling evidence for the presence of plasmoids, by revealing highly dynamic and rapidly moving brightenings that are smaller than 0.2 arcsec and that evolve on timescales of order seconds. Our interpretation of the observations is supported by detailed comparisons with synthetic observables from advanced numerical simulations of magnetic reconnection and associated plasmoids in the chromosphere. Our results highlight how subarcsecond imaging spectroscopy sensitive to a wide range of temperatures combined with advanced numerical simulations that are realistic enough to compare with observations can directly reveal the small-scale physical processes that drive the wide range of phenomena in the solar atmosphere.

description: The evolution of white dwarfs is essentially a cooling process that depends primarily on the energy stored in their degenerate cores and on the transparency of their envelopes. In this paper we compute accurate cooling sequences for carbon-oxygen white dwarfs with hydrogen dominated atmospheres for the full range of masses of interest. For this purpose we use the most accurate available physical inputs for both the equation of state and opacities of the envelope and for the thermodynamic quantities of the degenerate core. We also investigate the role of the latent heat in the computed cooling sequences. We present separately cooling sequences in which the effects of phase separation of the carbon-oxygen binary mixture upon crystallization have been neglected, and the delay introduced in the cooling times when this mechanism is properly taken into account, in order to compare our results with other published cooling sequences which do not include a treatment of this phenomenon. We find that the cooling ages of very cool white dwarfs with pure hydrogen atmospheres have been systematically underestimated by roughly 1.5 Gyr at log(L/Lo)=-4.5 for an otherwise typical 0.6 Mo white dwarf, when phase separation is neglected. If phase separation of the binary mixture is included then the cooling ages are further increased by roughly 10%. Cooling tracks and cooling isochrones in several color-magnitude diagrams are presented as well.

description: Mindfulness-based interventions that span multiple sessions over time appear to confer psychological benefits. However, the effects of brief periods of mindfulness meditation training are less clear, particularly on measures of cognitive functioning. This study assessed whether brief mindfulness practice (breath awareness) or training in two other contemplative practices – loving-kindness and gratitude – differentially impact working memory performance following acute physiological stress relative to an attentional control. Participants (n = 162) were randomly assigned to one of four training groups and completed the automated Operation Span (OSPAN) task pre-training and again after undergoing the cold pressor task. Three of the four groups improved in OSPAN performance, with loving-kindness, gratitude, and attentional control conditions showing increases in OSPAN relative to breath awareness. Changes in OSPAN were not correlated with changes in positive or negative affect. It appears that brief breath awareness training may not effectively buffer against acute stress in this predominantly meditation naïve sample and may in fact impair subsequent cognitive performance relative to a control or other contemplative practices. A granular approach is warranted to understand potentially distinct and contextually variable effects of different contemplative practices. Implications are discussed in light of the stress buffering hypothesis and Monitor and Acceptance Theory. Trial registration:ClinicalTrials.gov identifier: NCT02214264.

description: We report a high field investigation (up to 45 T) of the metamagnetic transition in CeIrIn$_5$ with resistivity and de-Haas-van-Alphen (dHvA) effect measurements in the temperature range 0.03-1 K. As the magnetic field is increased the resistivity increases, reaches a maximum at the metamagnetic critical field, and falls precipitously for fields just above the transition, while the amplitude of all measurable dHvA frequencies are significantly attenuated near the metamagnetic critical field. However, the dHvA frequencies and cyclotron masses are not substantially altered by the transition. In the low field state, the resistivity is observed to increase toward low temperatures in a singular fashion, a behavior that is rapidly suppressed above the transition. Instead, in the high field state, the resistivity monotonically increases with temperature with a dependence that is more singular than the iconic Fermi-liquid, temperature-squared, behavior. Both the damping of the dHvA amplitudes and the increased resistivity near the metamagnetic critical field indicate an increased scattering rate for charge carriers consistent with critical fluctuation scattering in proximity to a phase transition. The dHvA amplitudes do not uniformly recover above the critical field, with some hole-like orbits being entirely suppressed at high fields. These changes, taken as a whole, suggest that the metamagnetic transition in CeIrIn$_5$ is associated with the polarization and localization of the heaviest of quasiparticles on the hole-like Fermi surface.

description: Understanding the microscopic behavior of the black holes ingredients has been one of the important challenges in black holes physics during the past decades. In order to shed some light on the microscopic structure of black holes, in this paper, we explore a recently observed phenomenon for black holes namely reentrant phase transition, by employing the Ruppeiner geometry. Interestingly enough, we observe two properties for the phase behaviour of small black holes that leads to reentrant phase transition. They are correlated and they are of the interaction type. For the range of pressure in which the system underlies reentrant phase transition, it transits from large black holes phase to small one which possesses higher correlation than the other ranges of pressures. On the other hand, the type of interaction between small black holes near large/small transition line, differs for usual and reentrant phase transitions. Indeed, for usual case, the dominant interaction is repulsive whereas for reentrant case we encounter with an attractive interaction. We show that in reentrant phase transition case, the small black holes behave like a Bosonic gas whereas in the usual phase transition case, they behave like a quantum anyon gas.

description: In this Letter we use the unprecedented spatial resolution of the Chandra X-ray Observatory to carry out, for the first time, a measurement of the post-shock electron temperature and proper motion of a young SNR, specifically to address questions about the post-shock partition of energy among electrons, ions, and cosmic rays. The expansion rate, 0.100 +/- 0.025 percent per yr, and inferred age, ~1000 yr, of E0102.2-7219, from a comparison of X-ray observations spanning 20 years, are fully consistent with previous estimates based on studies of high velocity oxygen-rich optical filaments in the remnant. With a radius of 6.4 pc for the blast wave estimated from the Chandra image, our expansion rate implies a blast wave velocity of ~6000 km/s and a range of electron temperatures 2.5 - 45 keV, dependent on the degree of collisionless electron heating. Analysis of the Chandra ACIS spectrum of the immediate post-shock region reveals a thermal plasma with abundances and column density typical of the Small Magellanic Cloud and an electron temperature of 0.4-1 keV. The measured electron temperature is significantly lower than the plausible range above, which can only be reconciled if we assume that a significant fraction of the shock energy, rather than contributing to the heating of the post-shock electrons and ions, has gone into generating cosmic rays.
