description: Cell growth is well described at the population level, but precisely how nutrient and water uptake and cell wall expansion drive the growth of single cells is poorly understood. Supported by measurements of single-cell growth trajectories and cell wall elasticity, we present a single-cell growth model for yeast. The model links the thermodynamic quantities, such as turgor pressure, osmolarity, cell wall elasto-plasticity, and cell size, applying concepts from rheology and thin shell theory. It reproduces cell size dynamics during single-cell growth, budding, and hyper-osmotic or hypo-osmotic stress. We find that single-cell growth rate and final size are primarily governed by osmolyte uptake and consumption, while bud expansion requires additionally different cell wall extensibilities between mother and bud. Based on first principles the model provides a more accurate description of size dynamics than previous attempts and its analytical simplification allows for easy combination with models for other cell processes.

description: To understand how knowledgeable and equipped the law enforcement agents in Nigeria are to enforce the drink-drive law. We conducted a descriptive cross-sectional study of Law Enforcement Agents in four Nigerian states selected by convenient sampling. The study utilized a pre-tested questionnaire designed to obtain subjects’ demographic data, elicit their knowledge about drink-drive law, and understand how equipped the subjects are. A team member walked respondents through the questions to ensure comprehension and accuracy with completion of the questions. 496 law enforcement agents were studied. They were 414(83.5%) male and 82(16.5%) females, mostly aged 21-40 years (64.3%). Close to half (48.2%) were police officers, while 35.7% were officers in the Federal Road Safety Corp (FRSC). 45% of respondents had secondary/high school education, while 39.5% had bachelor’s degree; with a significant majority in the FRSC. 269(54.2%) respondents had convicted a road user of drunk driving/riding on the basis of subjective assessment. The use of breathalyzers and awareness of permissible Blood Alcohol Concentration (BAC)/Breath Alcohol Concentration (BrAC), was reported by a few respondents (5%), mostly FRSC officers, and others with relatively higher educational attainment. The majority were ignorant of the approved BAC limit in Nigeria (0.05 g/100 dl) and objective methods of assessing breath alcohol concentrations. In Nigeria, there is a huge knowledge gap on the drink-drive law and the acceptable penalties for offenders in Nigeria among law enforcement agents. The law enforcement agents lack equipment for objectively detecting drunk driving among road users. Our findings call for an urgent intervention in the training and practice of law enforcement agents if the prevalence of RTC arising from drunk driving will be reduced in Nigeria.

description: An anomalous transient in the early Hubble-type (S0) galaxy Messier 85 (M85) in the Virgo cluster was discovered by Kulkarni et al. (2007) on 7 January 2006 that had very low luminosity (peak absolute R-band magnitude MR of about -12) that was constant over more than 80 days, red colour and narrow spectral lines, which seem inconsistent with those observed in any known class of transient events. Kulkarni et al. (2007) suggest an exotic stellar merger as the possible origin. An alternative explanation is that the transient in M85 was a type II-plateau supernova of extremely low luminosity, exploding in a lenticular galaxy with residual star-forming activity. This intriguing transient might be the faintest supernova that has ever been discovered.

description: To evaluate the impact of visually significant blepharoptosis and dermatochalasis on driving safety and performance. Patients with visually significant blepharoptosis often complain of difficulty with driving, but the impact of blepharoptosis on driving has not been evaluated in a real-world setting. Retrospective cohort study of 610 consecutive adult patients undergoing bilateral functional blepharoplasty or ptosis repair surgery at a single, University-based practice between 2014 and 2017. This cohort had a median age of 65 and was predominantly female. Pre-operative rates of motor vehicle collisions (MVCs) and moving violations (MVs) extracted from state Department of Transportation (DOT) records were compared with post-operative rates, using each patient as their own control. Poisson models were used for analysis. Subjects were included in the study for a median of 730 days before eyelid surgery (IQR 346 − 730) and 783 days after surgery (IQR 449 − 1176). There were 30 total MVCs before surgery (0.024 per subject, per year) and 48 after surgery (0.036 per subject, per year) (p = 0.08). There were 81 MVs before surgery (0.065 per subject, per year) and 66 after (0.049 per subject, per year) (p = 0.11). The multivariable model comparing MVCs pre- versus post-surgery adjusting for age, ptosis severity, gender, and comorbidities yields a rate ratio of 0.63 (p = 0.05). The multivariable model comparing MVs pre- versus post-surgery demonstrates a rate-ratio of 1.2 (p = 0.20). Older age was associated with lower rates of moving violations (coefficient of −0.03, p In this cohort, visually significant blepharoptosis and dermatochalasis were not associated with rates of MVCs or MVs. Further work is needed to study the impact of these common conditions on driving, for example adjusting MVC and MV rates by miles driven, which may influence decisions about when to operate on ptotic eyelids.

description: We study the excitation energy spectrum in the S=1/2 ferromagnetic Ising spin chain with the easy axis z in a magnetic field h={h_x,0,h_z}. According to Wu and McCoy's scenario of weak confinement, the fermionic spinon excitations (kinks), being free at h_z = 0 in the ordered phase, are coupled into bosonic bound states at arbitrary small h_z. We calculate the energy spectrum of such excitations in the leading order in small h_z, using different perturbative methods developed for the similar problem in the Ising field theory.

description: Novice adolescent drivers have a higher propensity to engage in risky driving and are at higher odds of being involved in collisions. Graduated driver licensing programs have been instituted to help novice drivers gain experience while avoiding higher risk driving circumstances. This study examines modifiable risk factors contributing to novice adolescent driver fault in collisions. Police traffic collision report data from municipalities in Alberta for the years 2010–2016, inclusive, were used. Fault in collision was assigned using an automated and previously validated tool for assigning culpability. Factors contributing to novice adolescent (16-19 years of age) fault in collision were examined using multivariable logistic regression. Novice adolescent drivers had higher adjusted odds ratios (aOR) of being at-fault in collision when driving from 01:00-05:00 (aOR = 1.38; 95% Confidence Interval [CI]: 1.26-1.50). Novice adolescent drivers had lower odds of fault when driving with an adult (aOR= 0.62; 95% CI: 0.57-0.68) or a single peer (aOR= 0.87; 95% CI: 0.80-0.94), but higher odds of causing a severe collision with a single peer present (aOR= 2.23; 95% CI: 1.21-4.11). Impairment of the teen driver was reported in 25% of all fatal collisions, and 40% of late-night fatal collisions. The findings support policies that allow driving with a single adult or peer passenger during daytime hours. Driving during late-night hours should be restricted for novice adolescent drivers.

description: We present arcsecond-scale mid-ir photometry (in the 10.5 micron N band and at 24.8 microns), and low resolution spectra in the N band (R~100) of a candidate high mass protostellar object (HMPO) in IRAS 18151-1208 and of two HMPO candidates in IRAS 20343+4129, IRS 1 and IRS 3. In addition we present high resolution mid-ir spectra (R~80000) of the two HMPO candidates in IRAS 20343+4129. These data are fitted with simple models to estimate the masses of gas and dust associated with the mid-ir emitting clumps, the column densities of overlying absorbing dust and gas, the luminosities of the HMPO candidates, and the likely spectral type of the HMPO candidate for which [Ne II] 12.8 micron emission was detected (IRAS 20343+4129 IRS 3). We suggest that IRAS 18151-1208 is a pre-ultracompact HII region HMPO, IRAS 20343+4129 IRS 1 is an embedded young stellar object with the luminosity of a B3 star, and IRAS 20343+4129 IRS 3 is a B2 ZAMS star that has formed an ultracompact HII region and disrupted its natal envelope.

description: Unsupervised Video Object Segmentation (UVOS) refers to the challenging task of segmenting the prominent object in videos without manual guidance. In recent works, two approaches for UVOS have been discussed that can be divided into: appearance and appearance-motion-based methods, which have limitations respectively. Appearance-based methods do not consider the motion of the target object due to exploiting the correlation information between randomly paired frames. Appearance-motion-based methods have the limitation that the dependency on optical flow is dominant due to fusing the appearance with motion. In this paper, we propose a novel framework for UVOS that can address the aforementioned limitations of the two approaches in terms of both time and scale. Temporal Alignment Fusion aligns the saliency information of adjacent frames with the target frame to leverage the information of adjacent frames. Scale Alignment Decoder predicts the target object mask by aggregating multi-scale feature maps via continuous mapping with implicit neural representation. We present experimental results on public benchmark datasets, DAVIS 2016 and FBMS, which demonstrate the effectiveness of our method. Furthermore, we outperform the state-of-the-art methods on DAVIS 2016.

description: We have obtained a position (at sub-arcsecond accuracy) of the submillimeter bright source GOODS 850-5 (also known as GN10) in the GOODS North field using the IRAM Plateau de Bure interferometer at 1.25 mm wavelengths (MM J123633+6214.1, flux density: S(1.25 mm)=5.0+-1.0 mJy). This source has no optical counterpart in deep ACS imaging down to a limiting magnitude of i(775)=28.4 mag and its position is coincident with the position found in recent sub-millimeter mapping obtained at the SMA (Wang et al. 2007). Using deep VLA imaging at 20 cm, we find a radio source (S(20 cm)=32.7+-4.3 microJy) at the same position that is significantly brighter than reported in Wang et al. The source is detected by Spitzer in IRAC as well as at 24 microns. We apply different photometric redshift estimators using measurements of the dusty, mid/far-infrared part of the SED and derive a redshift z~4. Given our detection in the millimeter and radio we consider a significantly higher redshift (e.g., z~6 Wang et al. 2007) unlikely. MM J123633+6214.1 alias GOODS 850-5 nevertheless constitutes a bright representative of the high-redshift tail of the submillimeter galaxy population that may contribute a significant fraction to the (sub)millimeter background.

Is the use of Christoffel connection in gravity theories conceptually correct?

Publisher: name: arXiv
Year: 2017
Subjects: subject: General Physics (physics.gen-ph)

description: Christoffel connection did not enter gravity as an axiom of minimal length for the free fall of particles (where anyway length action is not defined for massless particles), nor out of economy, but from the weak equivalence principle (gravitational force is equivalent to acceleration according to Einstein) together with the identification of the local inertial frame with the local Lorentz one. This identification implies that the orbits of all particles are given by the geodesics of the Christoffel connection. Here, we show that in the presence of only massless particles (absence of massive particles) the above identification is inconsistent and does not lead to any connection. The proof is based on the existence of projectively equivalent connections and the absence of proper time for null particles. If a connection derived by some kinematical principles for the particles is to be applied in the world, it is better these principles to be valid in all relevant spacetime rather than different principles to give different connections in different spacetime regions. Therefore, our result stated above may imply a conceptual insufficiency of the use of the Christoffel connection in the early universe where only massless particles are expected to be present (whenever at least some notions, like orbits, are meaningful), and thus of the total use of this connection. If in the early universe the notion of a massive particle, which appears latter in time, cannot be used, in an analogous way in a causally disconnected high-energy region (maybe deep interior of astrophysical objects or black holes) the same conclusions could be extracted if only massless particles are present.

title: Introducing the Texas Euclid Survey for Lyα (TESLA) Survey: Initial Study Correlating Galaxy Properties to Lyα Emission
Creators: name: Weaver, John R.
Publisher: name: University of Massachusetts Amherst
Year: 2023
Subjects: subject: Astrophysics and Astronomy

description: We present the Texas Euclid Survey for Lyα (TESLA), a spectroscopic survey in the 10 deg2 of the Euclid North Ecliptic Pole (NEP) field. Using TESLA, we study how the physical properties of Lyα emitters (LAEs) correlate with Lyα emission to understand the escape of Lyα emission from galaxies at redshifts of 2–3.5. We present an analysis of 43 LAEs performed in the NEP field using early data from the TESLA survey. We use Subaru Hyper Suprime-Cam imaging in the grizy bands, Spitzer/IRAC channels 1 and 2 from the Hawaii 20 deg2 (H20) survey, and spectra acquired by the Visible Integral-Field Replicable Unit Spectrograph (VIRUS) on the Hobby–Eberly Telescope. We perform spectral energy distribution (SED) fitting to compute the galaxy properties of 43 LAEs, and study correlations between stellar mass, star formation rate (SFR), and dust to the Lyα rest-frame equivalent width (WLyα). We uncover marginal (1σ significance) correlations between stellar mass and WLyα, and SFR and WLyα, with a Spearman correlation coefficient of −0.34−.14+.17 and −0.37−.14+.16, respectively. We show that the WLyα distribution of the 43 LAEs is consistent with being drawn from an exponential distribution with an e-folding scale of W0 = 150 Å. Once complete the TESLA survey will enable the study of ≳50,000 LAEs to explore more correlations between galaxy properties and WLyα. The large sample size will allow the construction of a predictive model for WLyα as a function of SED-derived galaxy properties, which could be used to improve Lyα-based constraints on reionization.

description: Knowledge about the collective dynamics of cortical spiking is very informative about the underlying coding principles. However, even most basic properties are not known with certainty, because their assessment is hampered by spatial subsampling, i.e. the limitation that only a tiny fraction of all neurons can be recorded simultaneously with millisecond precision. Building on a novel, subsampling-invariant estimator, we fit and carefully validate a minimal model for cortical spike propagation. The model interpolates between two prominent states: asynchronous and critical. We find neither of them in cortical spike recordings across various species, but instead identify a narrow reverberating regime. This approach enables us to predict yet unknown properties from very short recordings and for every circuit individually, including responses to minimal perturbations, intrinsic network timescales, and the strength of external input compared to recurrent activation - thereby informing about the underlying coding principles for each circuit, area, state and task.

description: This paper has been accepted for iPRES2018 and presents new work by Artefactual, Arkivum, Preservica and Jisc on how Preservation Action Registries (PAR) could be used to capture and share technical best practice for the preservation of digital objects in the form of a corpus of machine-readable recommendations. The registry’s data model defines what tools can be used for different digital object formats, what properties can be extracted or measured and what preservation actions can be taken. The model includes contextual and historical information on the reasons why recommendations are being given. The information is versioned and includes the tool parameters and software environments needed to execute different preservation actions so they are directly ‘executable’ by preservation systems. Our model makes registry content accessible through APIs using a distributed set of registries rather than a single canonical source. In this way, information can be made available from a range of sources including central registries (moderated and curated) or by exchange directly between trusted peer institutions or systems. Preservation systems such as Archivematica and Preservica are able to publish to and consume content from these registries.

description: We demonstrate the general existence of a local dipole conservation law in bosonic field theory. The scalar charge density arises from the symplectic form of the system, whereas the tensor current descends from its stress tensor. The algebra of spatial translations becomes centrally extended in presence of field configurations with a finite nonzero charge. Furthermore, when the symplectic form is closed but not exact, the system may, surprisingly, lack a well-defined momentum density. This leads to a theorem for the presence of additional light modes in the system whenever the short-distance physics is governed by a translationally invariant local field theory. We also illustrate this mechanism for axion electrodynamics as an example of a system with Nambu--Goldstone modes of higher-form symmetries.

subject: Early childhood education

description: Sensitive, responsive, and attuned interactions with educators provide the foundations for the infant’s cognitive, social and emotional development in early childhood education and care (ECEC). Reflection and reflective practice are foundational to the provision of high quality ECEC settings both within traditional and Montessori practice, however, there is sparse research into the reflective practice of Montessori 0-3 educators. This study examines: 1) how educators in Montessori services reflect on emotion and emotional labour 2) if reflective practice in Montessori early childhood services supports educator responsiveness to infant-toddler emotion. Data were collected through an exploratory online survey. Australian participants were recruited through email invitation to all centre directors of services including the name “Montessori” listed on the Australian Children’s Education & Care Quality Authority (ACECQA) national early childhood database, via peak bodies and through a Montessori 0-3 professionals’ Facebook page. International participants were recruited though Montessori peak bodies in English speaking countries with a strong Montessori presence and via a Google group for Association Montessori International (AMI) 0-3 qualified educators. The survey invited participants to respond to a series of vignettes and open-ended questions to prompt examples of professional practices and reflections in relation to both their own and infant-toddler emotions. They were then asked to self-assess the frequency of their pedagogical and critical reflection practices for 24 questions adapted from Larrivee (2008), with opportunity to add written comments. A total of 38 educators (23 Australian; 15 international) participated. Written responses were analysed using critical theory and deductively coded to Brookfield’s (1998) four lenses of critical reflection, encompassing: autobiographical lens; child lens; colleague lens; lens of literature. Qualitative analyses showed that participants acknowledged the importance of reflecting through their own lived experiences and personal beliefs - how their autobiography affects the way they receive and respond to information. There was also clear evidence of participants’ considering the child perspective with frequent references to observation as a foundational pedagogical practice to support their ability to meet the needs of the child. Participants also referred to engagement with Montessori and broader academic literature to support their practice. Quantitative analyses revealed high rates of reflective practice by all participants. Comparisons using t-tests showed that having a Montessori qualification and more experience of working in a Montessori environment were more likely to engage more frequently in some aspects of reflective practice.

description: The recent trends of increasing unpredictability of traffic demand and the proliferation of networked devices have led to a demand for a traffic engineering application which views network robustness as a crucial factor. Robustness refers to the resilience of infrastructure networks against random and targeted failures, caused by traffic shifts, natural disasters and Denial of Service (DoS) attacks. In this paper, the author developed an application to assign the links of the network a criticality value and finds the least critical path or in other terms, the most robust path. The dynamics of the network are translated to graph metrics and the application optimizes these metrics to determine the most robust path in the network. The developed application can be further extended by incorporating its output as a feedback mechanism for another application developed for automation of the network system for robustness. The application was written in Python 2 and implemented on Ubuntu 14.04.4.

description: Researchers have found a variety of uses for the Hybrid III (HIII) dummy that fall beyond the scope of its original purpose as an automotive crash test dummy. Some of these expanded roles for the HIII introduce situations that were not envisioned in the dummy’s original design parameters, such as a relatively rapid succession of tests or outdoor testing scenarios where temperature is not easily controlled. This study investigates how the axial compressive stiffness of the HIII lumbar spine component is affected by the duration of the time interval between tests. Further, it measures the effect of temperature on the compressive stiffness of the lumbar spine through a range of temperatures relevant to indoor and outdoor testing. High-rate axial compression tests were run on a 50th percentile male HIII lumbar component in a materials testing machine. To characterize the effects of tests recovery intervals, between-test recovery was varied from 2 hours to 1 minute. To quantify temperature effects, environmental temperature conditions of 12.5°, 25°, and 37.5 °C were tested. During repeated compressive loading, the force levels decreased consistently across long and short rest intervals. Even after 2 hours of rest between tests, full viscoelastic recovery was not observed. Temperature effects were pronounced, resulting in compressive force differences of 261% over the range of 12.5° to 37.5 °C. Compared to the stiffness of the lumbar at 25 °C, the stiffness at 37.5 °C fell by 40%; at 12.5 °C, the stiffness more than doubled, increasing by 115%. A modest decrease in temperature can be sufficient to dramatically change the response and repeatability of the lumbar HIII component in compressive loading. The large magnitude of the temperature effect has severe implications in its ability to overwhelm the contributions of targeted test variables. These findings highlight the importance of controlling, monitoring and reporting temperature conditions during HIII testing, even in indoor laboratory environments.

description: Since the 1998 proposal to build a quantum computer using dopants in semiconductors as qubits, much progress has been achieved on semiconductors nano fabrication and control of charge and spins in single dopants. However, an important problem remains, which is the control at the atomic scale of the dopants positioning. We propose to circumvent this problem by using 2 dimensional materials as hosts. Since the first isolation of graphene in 2004, the number of new 2D materials with favorable properties for electronics has been growing. Dopants in 2 dimensional systems are more tightly bound and potentially easier to position and manipulate. Considering the properties of currently available 2D materials, we access the feasibility of such proposal in terms of the manipulability of isolated dopants (for single qubit operations) and dopant pairs (for two qubit operations). Our results indicate that a wide variety of 2D materials may perform at least as well as the currently studied bulk host for donor qubits.

description: Distributed Byzantine fault-tolerant systems require frequent checkpoints of the application state to perform periodic garbage collection and enable faulty replicas to recover efficiently. State-of-the-art checkpointing approaches for replicated systems either cause significant service disruption when the application state is large, or they are unable to produce checkpoints that are verifiable across replicas. To address these problems we developed and evaluated deterministic fuzzy checkpointing, a technique to create consistent and verifiable checkpoints in parallel with request execution.

description: The objective of the present study is twofold: (i) to explore the riding behavior of motorcyclists while speeding, based on detailed riding analytics collected by smartphone sensors, and (ii) to investigate whether personalized feedback can improve motorcyclist behavior. In order to achieve the objective, a naturalistic riding experiment with a sample of 13 motorcyclists based on a smartphone application developed within the framework of the BeSmart project was conducted. Using risk exposure and riding behavior indicators calculated from smartphone sensor data, Generalized Linear Mixed-Effects Models are calibrated to correlate the percentage of riding time over the speed limit with other riding behavior indicators. An overall model was developed for all trips, as well as separate models for the parts of trips realized on different road types (urban and rural). Results indicate that the parameters of trip duration, distance driven during risky hours, morning peak hours and the number of harsh accelerations are all determined as statistically significant and positively correlated with the percentage of speeding time. Additionally, the provision of rider feedback and riding during afternoon peak hours are statistically significant and correlated with decreased percentages of speeding time. The outcomes of this study entail both scientific and social impacts. The present research contributes a preliminary example of the quantitative documentation of the impact of personalized rider feedback on one of the most important human risk factors; speeding. The ultimate objective when providing feedback to riders is to: (i) trigger their learning and self-assessment process, thus enabling them to gradually improve their performance and (ii) monitor the shift of riding behavior as the application provides feedback. The present results capture and quantify the positive effects of rider feedback, thus providing needed impetus for larger-scale applications as well as relevant policy interventions.

Heating mechanism affects equipartition in a binary granular system

description: Two species of particles in a binary granular system typically do not have the same mean kinetic energy, in contrast to the equipartition of energy required in equilibrium. We investigate the role of the heating mechanism in determining the extent of this non-equipartition of kinetic energy. In most experiments, different species of particle are unequally heated at the boundaries. We show by event-driven simulations that this differential heating at the boundary influences the level of non-equipartition even in the bulk of the system. This conclusion is fortified by studying a numerical model and a solvable stochastic model without spatial degrees of freedom. In both cases, even in the limit where heating events are rare compared to collisions, the effect of the heating mechanism persists.

description: Let X be a smooth compactification of a homogeneous space of a linear algebraic group G over a number field k. We establish the conjecture of Colliot-Thélène, Sansuc, Kato and Saito on the image of the Chow group of zero-cycles of X in the product of the same groups over all the completions of k. When G is semisimple and simply connected and the geometric stabiliser is finite and supersolvable, we show that rational points of X are dense in the Brauer-Manin set. For finite supersolvable groups, in particular for finite nilpotent groups, this yields a new proof of Shafarevich's theorem on the inverse Galois problem, and solves, at the same time, Grunwald's problem, for these groups. ----- Soit X une compactification lisse d'un espace homogène d'un groupe algébrique linéaire G sur un corps de nombres k. Nous établissons la conjecture de Colliot-Thélène, Sansuc, Kato et Saito sur l'image du groupe de Chow des zéro-cycles de X dans le produit des mêmes groupes sur tous les complétés de k. Lorsque G est semi-simple et simplement connexe et que le stabilisateur géométrique est fini et hyper-résoluble, nous montrons que les points rationnels de X sont denses dans l'ensemble de Brauer-Manin. Pour les groupes finis hyper-résolubles, en particulier pour les groupes finis nilpotents, cela donne une nouvelle preuve du théorème de Shafarevich sur le problème de Galois inverse et résout en même temps, pour ces groupes, le problème de Grunwald.

description: Recent progress in the understanding of gravity on noncommutative spaces is discussed. A gravity theory naturally emerges from matrix models of noncommutative gauge theory. The effective metric depends on the dynamical Poisson structure, absorbing the degrees of freedom of the would-be U(1) gauge field. The gravity action is induced upon quantization.

description: We study a continuum model of the weakly interacting Bose gas in the presence of an external field with minima forming a triangular lattice. The second lowest band of the single-particle spectrum ($p$-band) has three minima at non-zero momenta. We consider a metastable Bose condensate at these momenta and find that, in the presence of interactions that vary slowly over the lattice spacing, the order parameter space is isomorphic to $S^{5}$. We show that the enlarged symmetry leads to the loss of topologically stable vortices, as well as two extra gapless modes with quadratic dispersion. The former feature implies that this non-Abelian condensate is a "failed superfluid" that does not undergo a Berezinskii-Kosterlitz-Thouless (BKT) transition. Order-by-disorder splitting appears suppressed, implying that signatures of the $S^5$ manifold ought to be observable at low temperatures.

description: A special vapour cell has been built, that allows the measurement of the atom-surface van der Waals interaction exerted by a CaF2 window at the interface with Cs vapour. Mechanical and thermal fragility of fluoride windows make common designs of vapour cells unpractical, so that we have developed an all-sapphire sealed cell with an internal CaF2 window. Although impurities were accidentally introduced when filling-up the prototype cell, leading to a line-broadening and shift, the selective reflection spectrum on the Cs D1 line (894 nm) makes apparent the weak van der Waals surface interaction. The uncertainties introduced by the effects of these impurities in the van der Waals measurement are nearly eliminated when comparing the selective reflection signal at the CaF2 interface of interest, and at a sapphire window of the same cell. The ratio of the interaction respectively exerted by a sapphire interface and a CaF2 interface is found to be 0.55 $\pm$ 0.25, in good agreement with the theoretical evaluation of ~0.67.
