Cyanogen ($\mathrm{C_2N_2}$) is suspected for a long time to be present in comets and contribute the creation of CN radical. So far no observations with ground-based facilities managed detect this species but Rosetta mission, thanks situ ROSINA mass spectrometer detected coma 67P/Churyumov-Gerasimenko. To investigate its presence from infrared spectra other comets, we developed fluorescence model $\nu_3$ fundamental band. From new laboratory high-resolution cyanogen, analyzed region band...
Context. CO is an abundant species in comets, creating + ion with emission lines that can be observed the optical spectral range. A good modeling of its fluorescence spectrum important for a better measurement abundance. Such species, if enough, also used to measure 12 C/ 13 C isotopic ratio. Aims. This study uses opportunity high content comet C/2016 R2 (PanSTARRS), which created bright range, build and test new model this ratio chemical first time ground-based observations. Methods. Thanks...
We introduce CaSDa24, the latest iteration of our high-resolution molecular spectroscopy database cluster. Comprising ten independent databases, each dedicated to a specific molecule (CH4, CH3Cl, SF6, C2H4, CF4, GeH4, RuO4, SiF4, UF6, SiH4), CaSDa24 integrates updated and new databases since previous publication. These include detailed lists calculated spectral lines, eigenvectors, energy levels, additional relevant information derived from experimental spectra analyses. This article...
Historically, the practice in velocity model building usually resorted to one of two approaches: layer-based and gridded (Jones, 2003). For North Sea type environments where sedimentary interfaces delimit changes field geology 'lends itself' a representation, approach has hitherto been commonly used. In other words, we have encouraged preconceived bias, as consider it be meaningful geological constraint on solution. Conversely, is adopted regime decoupled from sedimentation, governed...
In the last five years, fine Burmese blue sapphires from Baw Mar area of Mogok have reached market.The faceted stones typically show a strong pleochroism greenish to violetish when viewed perpendicular and parallel c-axis, respectively, with medium saturation dark tone.Most samples were relatively clean under microscope, showing multiple twinning whitish needle-like inclusions (presumably boehmite) at intersections.Often, these associated stress tension fissures.Needles, most likely rutile,...
Calibration of energy flow models for cabin environments requires tools able to measure the between sub-systems models. Here we shall specifically consider acoustic in and vibration panels. Sound intensity measurement, example with a two-microphone probe, can provide total sound at some distance from It cannot resolve, how much is due radiation surface absorption field. And it information right on panel surface, leading degraded resolution. The ability distinguish radiated absorbed important...

The aim of this study was to determine, in infants born at <29 weeks postmenstrual age until 32 age, whether reduction light stimulation by occlusion eyes affected central visual development. pattern visual‐evoked potential responses 41 and 51 3 y did not differ between subjected or ocular occlusion. Hence, an early marked preterm does seem deleterious
Soft error rate (SER) models have been used within IBM since the early sixties to determine capacity capabilities, of diskfiles. Most consider data handling capabilities and mechanical misregistration TPI for a given system rate. Recent estimate factory yields, field performance distributions, effects manufacturing tolerances. The authors describe most recent hybrid which are estimating soft rates on high designs. Particular attention is modified SER model stress model.< <ETX...
Over the past 20 years, ray-based post-migration reflection tomography has remained largely unchallenged as a velocity model building tool for seismic depth imaging. While other methods have been proposed, they yet to be adopted into standard workflows. The decisive elements such tools are: accuracy, resolution, flexibility, ease of use, and turnaround time. success domain comes from good balance it offers between those elements. This paper aims illustrate with few practical innovations in...
In some cases it is important to be able measure not only the total sound intensity on a panel surface in vehicle cabin, but also components of that due radiation and absorption from incident field. For example, these may needed for calibration energy flow models cabin noise. Two different methods are introduced present paper: one based coefficient admittance. The two compared terms underlying assumptions through simulated real measurements. method appears more robust.
Interest in the biological roles of cell membrane–derived vesicles cell–cell communication has increased recent years. Microparticles (MPs) are one such type vesicles, ranging diameter from 0.1 μm to 1 μm, and typically shed plasma membrane eukaryotic cells undergoing activation or apoptosis. Here we describe generation T lymphocyte–derived microparticles (LMPs) apoptotic CEM stimulated with actinomycin D. LMPs isolated through a multistep differential centrifugation process characterized...

Among the limited number of space missions dedicated to cometary science, Rosetta spacecraft launched in 2004 significantly enhanced understanding those small bodies, by conducting a two-year study comet 67P/Churyumov-Gerasimenko. One Rosetta&#8217;s instruments, mass spectrometer ROSINA, discovered numerous chemical species coma that had never been observed comets before. such species, cyanogen (C2N2) is linear molecule previously only Titan&#8217;s atmosphere (Kunde et al. 1981)...
IntroductionComets are pristine relics of the early Solar System, formed from agglomeration icy grains and dust particles, offering insights into evolution protosolar nebula (PSN). Despite their usual water-ice richness, blue comet C/2016 R2 (PanSTARRS) exhibited atypical abundance ratios, with an H2O/CO upper limit less than 0.32% [1], weak CN lines [2], exceptionally high N2/CO ratio 0.09 [3], suggesting unique formation conditions. Our study revisits historical observations a comet,...
Context . The long-period comet C/1908 R1 (Morehouse) is distinguished by its early spectroscopic tail photography, which uncovered notably intense emission bands of N 2 + and CO , similar to the unusual characteristics atypical blue C/2016 R2 (Pan-STARRS). Aims To probe potential parallels with further, we revisited historical plates while leveraging New Astrometric Reduction Old Observations (NAROO) project’s advanced sub-micrometric scanner. Methods We first reviewed intensity ratio...
Abstract Background Timely and effective pre-hospital management of penetrating neck injuries (PNI) is critical to improve patient outcomes. Pre-hospital interventions in patients with PNI can be especially challenging due the anatomical injury site coupled a resource-limited environment. Nationally, United Kingdom, no consensus statement or expert agreed guidance exists on how best manage setting. Method We conducted national modified e-Delphi study subject matter experts (SMEs) from...
