description: It is reasonably well-known that birefringent crystal optics can to some extent be described by the use of pseudo-Finslerian spacetimes (an extension of pseudo-Riemannian spacetime). What is less commonly appreciated is that there are two separate and quite disjoint pseudo-Finsler structures for the two photon polarizations, and further, that there are separate tangent-space pseudo-Finsler structures defined by the group velocity and co-tangent-space pseudo-co-Finsler structures defined by the phase velocity. The inter-connections between these four separate pseudo-Finsler structures are rather subtle. One particular source of technical difficulty is the fact that because physicists need to use pseudo-Finsler structures to describe propagation of signals, there will be nonzero null vectors in both the tangent and cotangent spaces -- this causes significant problems in that many of the mathematical results normally obtained for "usual'' (Euclidean signature) Finsler structures either do not apply, or require significant modifications to their formulation. We shall first provide a few basic definitions, and then present a tutorial outline of the relevant physics of birefringent optics, explicitly demonstrating the interpretation in terms of pseudo-Finsler spacetimes. We shall then discuss the tricky issues that arise when trying to inter-relate the various pseudo-Finsler structures we encounter, and finish by connecting these technical questions (which of course arise in what is a physically a very well-understood situation) back to ongoing research into possible extensions and modifications of general relativity.

Evaluation of homogenized thermal conductivities of imperfect carbon-carbon textile composites using the Mori-Tanaka method

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Three-scale homogenization procedure is proposed in this paper to provide estimates of the effective thermal conductivities of porous carbon-carbon textile composites. On each scale - the level of fiber tow (micro-scale), the level of yarns (meso-scale) and the level of laminate (macro-scale) - a two step homogenization procedure based on the Mori-Tanaka averaging scheme is adopted. This involves evaluation of the effective properties first in the absence of pores. In the next step, an ellipsoidal pore is introduced into a new, generally orthotropic, matrix to make provision for the presence of crimp voids and transverse and delamination cracks resulting from the thermal transformation of a polymeric precursor into the carbon matrix. Other sources of imperfections also attributed to the manufacturing processes, including non-uniform texture of the reinforcements, are taken into consideration through the histograms of inclination angles measured along the fiber tow path together with a particular shape of the equivalent ellipsoidal inclusion. The analysis shows that a reasonable agreement of the numerical predictions with experimental measurements can be achieved.

description: We assess the feasibility of detecting the compact object remnants from Population III (Pop III) stars in nearby dense star clusters, where they become luminous again as X-ray binaries (XRBs) and tidal disruption events (TDEs) via strong tidal encounters. Analytically modelling the formation of Pop III stars, coupled with a top-heavy initial mass function predicted by numerical simulations, we derive the number of (active) Pop III XRBs and TDEs in the present-day Milky Way (MW) nuclear star cluster as $\sim 0.06-0.3$ and $\lesssim 4\times 10^{-6}$, rendering any detection unlikely. The detection probability, however, can be significantly boosted when surveying all massive star clusters from the MW and neighboring galaxy clusters. Specifically, we predict $\sim 1.5-6.5$ and $\sim 40-2800$ active Pop III XRBs in the MW and the Virgo cluster, respectively. Our Pop III XRBs are dominated ($\sim 99\%$) by black holes with a typical mass and luminosity of $\sim 45$ $\rm M_{\odot}$ and $\sim 10^{36}$ $\rm erg\ s^{-1}$. Deep surveys of nearby ($\lesssim 30-300$ $\rm Mpc$) galaxy clusters for such Pop III XRBs are well within reach of next-generation X-ray telescopes, such as ATHENA and LYNX.

Inclusive Search for the SM Higgs Boson in the H->gammagamma channel at the LHC
Creators: name: Ganjour, Serguei

Year: 2008
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A prospective for the inclusive search of the Standard Model Higgs boson in the decay channel H->gammagamm is presented with the CMS experiment at the LHC. The analysis relies on a strategy to determine the background characteristics and systematics from data. The strategy is applied to a Monte Model of the QCD background, with full simulation of the detector response. The discrimination between signal and background exploits information on photon isolation and kinematics. The resolution for the reconstructed Higgs boson mass profits from the excellent energy resolution of the CMS crystal calorimeter. A discovery significance above 5 sigma is expected at integrated LHC luminosities below 30 inverse femtobarn for Higgs boson masses below 140 GeV/c^2.

description: The fully convolutional network (FCN) has achieved tremendous success in dense visual recognition tasks, such as scene segmentation. The last layer of FCN is typically a global classifier (1x1 convolution) to recognize each pixel to a semantic label. We empirically show that this global classifier, ignoring the intra-class distinction, may lead to sub-optimal results. In this work, we present a conditional classifier to replace the traditional global classifier, where the kernels of the classifier are generated dynamically conditioned on the input. The main advantages of the new classifier consist of: (i) it attends on the intra-class distinction, leading to stronger dense recognition capability; (ii) the conditional classifier is simple and flexible to be integrated into almost arbitrary FCN architectures to improve the prediction. Extensive experiments demonstrate that the proposed classifier performs favourably against the traditional classifier on the FCN architecture. The framework equipped with the conditional classifier (called CondNet) achieves new state-of-the-art performances on two datasets. The code and models are available at https://git.io/CondNet.

description: Background: A correlation between gut microbiome and mental health has drawn significant attention lately. The effects of microbiome microorganisms and their byproducts on disease states represent a complex and dynamic field of study. The objective of this article is to review the association of gut microbes and mental health and the effects of probiotics on psychiatric disorders, if any.

Methodology: This meta-analysis was conducted using the PRISMA standards. We have compiled the most recent advancements in the field according to human research published in this Systematic review and meta-analysis.

Results: The forest plot analysis revealed that probiotics or probiotics combined with other intervention modalities did significantly reduce some extent of mental disorders in comparison to the control group (Standardized mean difference) SMD = 0.95, 95% Confidence Interval (CI): −6.52 to 8.42, P value< 0.01.

Conclusion: Overall, the reviewed literature supports the importance of gut microbiota–brain interaction in human mental illnesses, including the impact of probiotics on mental health outcomes and brain connection.

description: The mass varying neutrino scenario is a model that successfully explains the origin of dark energy while at the same time solves the coincidence problem. The model is, however, heavily constrained by its stability towards the formation of neutrino bound states when the neutrinos become nonrelativistic. We discuss these constraints and find that natural, adiabatic, stable models with the right amount of dark energy today do not exist. Secondly, we explain why using the lightest neutrino, which is still relativistic, as an explanation for dark energy does not work because of a feedback mechanism from the heavier neutrinos.

description:  Background: In recent times, patients have become more aware of their rights, and this has led to significant rise in the
compensation cases against doctors. Due to the nature of the work and costs involved in the treatment, dental
professionals are at high risk of facing such medical negligence cases. Therefore, the present study was conducted to
assess knowledge and awareness regarding professional indemnity insurance (PII) among dental professionals in India.
Methodology: A systematic review of relevant cross-sectional observational studies was conducted among dental
professionals in India to report their knowledge and awareness regarding PII. Eight studies out of 98 were finally
included in the review after conducting both electronic and manual search of scientific databases and making necessary
exclusions. Potential biases were addressed and relevant data regarding PII data was extracted by the investigators
concerned.
Results: More than 60% of subjects had knowledge regarding PII in one of the study reports. Only 0.5% of subjects had
taken PII in one of the studies and merely 8% in the other study. One of the studies mentioned that 76.2% of subjects
paid compensation to their patients for negligence during dental treatment. Main hurdles for not opting PII were
unawareness and considering PII non-mandatory for dentists. More than 90% of subjects in one study showed interest in
buying PII for themselves.
Conclusion: The results of the present review reveal that less than half of the subjects in some studies reported a lack of
knowledge regarding PII and very few had taken PII. Therefore, there is an urgent need to make dental professionals
aware of the benefits of obtaining PII to safeguard themselves from various litigation issues.

description: Background: Reconstruction of the mandible following tumor resection or trauma can be challenging due to associated functional and esthetic problems. Various options have been described in the literature, but non-vascularized bone graft remain a viable option in middle- and low-income countries, Nigeria inclusive. We hereby report our experience with the use of non-vascularized bone graft with mandibular reconstruction plates in a double bridging technique for mandibular reconstruction in our institution.

Methodology: Patients who had mandibular defect reconstruction with non-vascularized bone graft between January 2012 and December 2021 were included in this study. Grafts were harvested from either the rib or contralateral iliac crest and secured with mandibular reconstruction plate and screws in a double bridging technique. Patients were followed for a minimum of 12 months and outcomes such as the level of patients’ satisfaction with appearance, graft take, bony continuity and complications were assessed and analyzed.

Result: Twenty eight patients comprising 18 males and 10 females [M:F 1.8:1] had mandibular defect reconstruction with double bridging technique during the study period. Donor site distribution revealed that 64.3% [n=18] had their grafts harvested from the iliac crest while the remaining 10 [35.7%] were taken from the rib. Ameloblastoma [75%, n=21] was the commonest lesion necessitating resection of the mandible amongst the subjects. The follow up result showed that appearance was satisfactory in 25 patients [89%], graft take/ restoration of bony continuity in 27 patients [96%], graft infection occurred in 2 patients [7.1%] while only one case of graft failure was established [3.6%]

Conclusion: A combination of non-vascularized bone graft with reconstruction plate in a bridging technique is a viable option for mandibular reconstruction in a resource-limited setting.

description: In einer digitalisierten Gesellschaft verliert das gedruckte Buch zunehmend an Bedeutung, sowohl im schulischen Kontext als auch in der gesellschaftlichen Wahrnehmung. Die zunehmende Technisierung und die Entwicklung neuer Medienformate haben aber nicht nur Auswirkungen auf die neuen Medien – auch die 'alten' Medien sind davon betroffen. Dieser Beitrag nimmt den Roman Schiff des Theseus der Autoren Doug Dorst und J. J. Abrams als Ausgangspunkt, um das literarische Wechselspiel im Bruch zwischen analogen und digitalen Medien zu thematisieren. Derartige Romane, die transmedial angesiedelt sind, vereinen die Ästhetik des Analogen mit den Erzählmöglichkeiten des Digitalen. Nach einer medientheoretischen Reflexion steht besonders auch die fachdidaktische Fragestellung nach den Möglichkeiten und Chancen eines medienorientierten Literaturunterrichts im Zentrum des Beitrags.

description: We have used the Taeduk Radio Astronomy Observatory to observe the Orion A and Ophiuchus clouds in the $J=$1$-$0 lines of $^{13}$CO, C$^{18}$O, HCN, HCO$^+$, and N$_2$H$^+$ and the $J=$2$-$1 line of CS. The fully sampled maps with uniform noise levels are used to create moment maps. The variations of the line intensity and velocity dispersion with total column density, derived from dust emission maps, are presented and compared to previous work. The CS line traces dust column density over more than one order of magnitude, and the N$_2$H$^+$ line best traces the highest column density regime ($\log(N_\mathrm{H_2}$) $>$ 22.8). Line luminosities, integrated over the cloud, are compared to those seen in other galaxies. The HCO$^+$-to-HCN luminosity ratio in the Orion A cloud is similar to that of starburst galaxies, while that in the Ophiuchus cloud is in between those of active galactic nuclei and starburst galaxies.

description: Background: Many studies have reported the negative impact of the COVID-19 pandemic on the rhythms and sleep in various populations. Particularly in frontline healthcare workers, which are highly susceptible to developing sleep disturbances. Therefore, the present study was conducted to determine the prevalence and determinants of sleep disturbances in healthcare workers at the regional Hospital Hassan II in Agadir, Morocco.

Methodology: A cross-sectional study among frontline healthcare workers was conducted at the Regional Hospital in Agadir, by administering an online questionnaire using the Google Forms platform distributed through social media. The questionnaire was anonymous, and data confidentiality was assured. Data analysis was performed using SPSS version 21.

Results: A total of 54 healthcare professionals filled in the questionnaire. The mean age was 28.81±05.35, The two-thirds were female participants (59.3%), and the mean Epworth score was 07.53±04.05, High prevalence rates of sleep disorders were reported as follows; sleep onset insomnia (27.4), excessive daytime sleepiness (24.1), snoring (24.1).We found that morning headaches and concentration difficulties are factors associated with sleep disorders among healthcare workers.

Conclusions: COVID-19 has a high risk of poor sleep quality, with many consequences. Measures to improve the sleep and well-being of healthcare workers are needed.

We prove the proposed idea by numerically solving the paraxial propagation equation in refraction index-modulated media, and we evaluate the efficiency of the process by plane-wave-expansion analysis. The technique can be applied to filter (to clean) the packages of atomic waves (Bose condensates), as well improve the directionality of acoustic and mechanical waves.

Suppose X has a full exceptional collection of sheaves, and these sheaves are invariant under the action of the group. We construct a semiorthogonal decomposition of bounded derived category of G-equivariant coherent sheaves on X into components, equivalent to derived categories of twisted representations of the group. If the group is finite or reductive over the algebraically closed field of zero characteristic, this gives a full exceptional collection in the derived equivariant category. We apply our results to particular varieties such as projective spaces, quadrics, Grassmanians and Del Pezzo surfaces.

description: The agricultural domain offers a working environment where many human laborers are nowadays employed to maintain or harvest crops, with huge potential for productivity gains through the introduction of robotic automation. Detecting and localizing humans reliably and accurately in such an environment, however, is a prerequisite to many services offered by fleets of mobile robots collaborating with human workers. Consequently, in this paper, we expand on the concept of a topological particle filter (TPF) to accurately and individually localize and track workers in a farm environment, integrating information from heterogeneous sensors and combining local active sensing (exploiting a robot's onboard sensing employing a Next-Best-Sense planning approach) and global localization (using affordable IoT GNSS devices). We validate the proposed approach in topologies created for the deployment of robotics fleets to support fruit pickers in a real farm environment. By combining multi-sensor observations on the topological level complemented by active perception through the NBS approach, we show that we can improve the accuracy of picker localization in comparison to prior work.
Alpine and subalpine vegetation in the southern Chilcotin Mountain rangelands of British Columbia

description: An ecological classification of high elevation range provides a framework for proper resource management. Alpine and subalpine vegetation in the Southern Chilcotin Mountains was studied to characterize the plant communities of the high elevation rangelands in the southern interior of British Columbia. The impacts of grazing on the structure and composition of the vegetation were evaluated. Two hundred and thirty-nine sites were sampled in a 10,000 ha area. Plots were selected randomly within homogeneous units delineated on 1:30,000 (40 chain) air photos prior to the field season. These were classified on the basis of physiognomy, dominant species and environmental conditions. The following nineteen community types were described: Picea engelmanii-Abies lasiocarpa forest, Pinus albicaulis-Juniperus communis forest, Salix bare layi-Carex aquatilis shrub wetland, Salix barrattiana alpine shrub wetland, Salix brachycarpa-Salix barclayi shrubland, Salix brachycarpa-Festuca spp. shrubfieId, Salix brachycarpa-Phleum alpinum shrubfieId, Arctostaphylos uva-ursi-Amelanchier alnifolia dry shrubland, Salix cascadensis dwarf willow shrubland, Dryas octopetala fellfield, Dryas octopetala-Festuca altaica alpine grassland, Carex aquatilis/rostrata wetland, Carex nigricans late snowbed meadow, Festuca altaica-Festuca brachyphylla meadow, Festuca brachyphylla meadow, Festuca brachyphylla-Phleum alpinum meadow, Phleum alpinum-Carex phaeocephala meadow, Koeleria cristata dry meadow, and crustose lichen rock-land or talus terrain unit. Changes in the structure and composition of plant communities in response to grazing pressure were evident on the more heavily used valley bottom meadow community types. After many years of use, Festuca altaica appears to have, been eliminated from heavily grazed meadows, there is a decrease in the height of the vegetation, an increase in the exposed bare ground, and an increase in the abundance of weedy species in all community types. Many of the community types described from this region are floristically and/or ecologically comparable with plant communities described from other high elevation areas in British Columbia, the southern Yukon, and the Pacific Northwest of the United States.

Methodology: This study was a multi-centre hospital-based prospective cross-sectional study of 250 parturient who had term deliveries in Port Harcourt. The socio-demographic data and the medical history of the parturient were collected using a proforma. The placenta was collected after delivery and examined, and the morphometric features were noted. Data analysis was done with SPSS IBM version 23. Correlation and Regression analysis were employed in investigating the relationship between maternal/neonatal characteristics and placental morphology. Statistical significance was at a p-level of less than 0.05.

Results: The mean age of the women ± SD = 30.44±4.1years and the median parity was para-2. Gestational Hypertension was the most common medical condition among participants. There was a statistically significant association between the maternal medical conditions and the placental shape with a preponderance of the oval shape among the women with hypertensive disorders. There was also, a statistically significant association between maternal medical conditions in pregnancy and other placental measurements such as weight, number of cotyledons, diameter, thickness, and cord insertion.

Conclusion: Maternal medical conditions in pregnancy was found to have significant macroscopic imprints on the placental morphology and these can help in the diagnosis and management of medical illnesses that complicate pregnancies in our environment. More research is needed to establish causation.

description: Background: Early detection of increasing numbers of cases of chromosomal abnormalities (aneuploides) at the Rivers State University Teaching Hospital (RSUTH) in the Niger Delta will enhance appropriate counseling of patients and early termination of the affected pregnancies. The study aimed to ascertain the prevalence of aneuploides at the RSUTH and to determine the necessity for early prenatal diagnosis in the Niger Delta.

 

Methodology: This was a prospective cross-sectional study carried out over a three-year period (01/01/2018 – 01/01/2021) at the RSUTH, Nigeria. Newborn babies delivered at 28 weeks and above were assessed at birth for the phenotypes of aneuploidy and associated birth defects. A convenient sampling method was used to recruit all the babies with chromosomal abnormalities and their mothers. Data including that of socio-demographic, obstetric characteristics, and the fetuses were taken and analyzed using Statistical Package for Social Sciences Version 23 (SPSS version 23). Quantitative variables were summarized using means and standard deviation while qualitative variables were expressed as frequencies and proportions.

 

Results: The total number of babies that were delivered by the 5868 participants in the study was 6078, out of which 10 cases of aneuploides were identified – 3 cases of trisomy 18 and 7 cases of Trisomy 21. The prevalence of chromosomal abnormalities at birth at the RSUTH was 0.165% of the total births, 1:2000 and 1:654 for T18 and T21 respectively. 1:654 mothers had babies with chromosomal abnormalities, 1:2000 and 1:833 for T18 and T21 respectively.

 

Conclusion: The prevalence of chromosomal abnormalities at birth at the RSUTH of 0.165% represented a gross underestimation because the diagnosis was based on the outward phenotypical appearance of the neonates and it was made not from babies delivered at 20 weeks and above as practiced in Europe and other countries, but from 28 weeks. Prenatal diagnosis was therefore highly recommended in the Niger Delta.

description: We have studied the electronic and magnetic structures of the ternary iron arsenides AFe$_2$As$_2$ (A = Ba, Ca, or Sr) using the first-principles density functional theory. The ground states of these compounds are in a collinear antiferromagnetic order, resulting from the interplay between the nearest and the next-nearest neighbor superexchange antiferromagnetic interactions bridged by As $4p$ orbitals. The correction from the spin-orbit interaction to the band structure is small. The pressure can reduce dramatically the magnetic moment and diminish the collinear antiferromagnetic order. Based on the calculations, we propose that the low energy dynamics of these materials is described effectively by a $t-J_H-J_1-J_2$-type model.

description: We present the results of semi-inclusive neutrino-nucleus cross sections within the plane wave impulse approximation (PWIA) for three nuclear models: relativistic Fermi gas (RFG), independent-particle shell model (IPSM) and natural orbital shell model (NO) in comparison with the available CC0$π$ measurements from the T2K, MINER$ν$A and MicroBooNE collaborations where a muon and at least one proton are detected in the final state. Results are presented as a function of the momenta and angles of the final particles, as well as in terms of the imbalances between proton and muon kinematics. The analysis reveals that contributions beyond PWIA are crucial to explain the experimental measurements and that the study of correlations between final-state proton and muon kinematics can provide valuable information on relevant nuclear effects such as the Fermi motion and final state interactions.

description: The in-plane lattice constants of close-packed planes of fcc and hcp Ni and Co match that of graphite almost perfectly so that they share a common two dimensional reciprocal space. Their electronic structures are such that they overlap in this reciprocal space for one spin direction only allowing us to predict perfect spin filtering for interfaces between graphite and (111) fcc or (0001) hcp Ni or Co. First-principles calculations of the scattering matrix show that the spin filtering is quite insensitive to amounts of interface roughness and disorder which drastically influence the spin-filtering properties of conventional magnetic tunnel junctions or interfaces between transition metals and semiconductors. When a single graphene sheet is adsorbed on these open $d$-shell transition metal surfaces, its characteristic electronic structure, with topological singularities at the K points in the two dimensional Brillouin zone, is destroyed by the chemical bonding. Because graphene bonds only weakly to Cu which has no states at the Fermi energy at the K point for either spin, the electronic structure of graphene can be restored by dusting Ni or Co with one or a few monolayers of Cu while still preserving the ideal spin injection property.

description: The physical mechanism for triggering the changing-look phenomenon in active galactic nuclei (AGNs) is still unclear. We explore this issue based on the multi-wavelength spectral and flux variations for a changing-look AGN Mrk~1018 with long-term observations in the X-ray, optical/ultraviolet(UV), and radio bands. Both the optical and the X-ray emission experience rapid decay in changing-look phase during 2010--2015, where a re-flare appears in the optical/UV and X-ray bands. We find a time lag of $\sim 20 $ days of optical/UV behind X-ray variations in type 1.9 phase. The 5 GHz radio flux decreases by $\sim 20$\% in type 1.9 phase during 2016--2017. We find both X-ray photon index ($Γ$) and the optical-to-X-ray spectral index (\alphaox\,) are anti-correlated with the Eddington scaled 2--10~keV X-ray luminosity ($L_\mathrm{X}/L_\mathrm{Edd}$) in the type 1.9 phase. However, the type 1 phase deviates from these two anti-correlations, which suggests that the change of broad emission lines might be regulated by the evolution of accretion disk (e.g., disappearing of the inner cold disk in the type 1.9 phase).

description: Die Rezension zu Robert Suters Par force. Jagd und Kritik ergänzt den Schwerpunkt der vorliegenden Ausgabe der MEDIENIMPULSE zum Thema Macht, Souveränität und Herrschaft . Ein bestechendes Beispiel der Darstellung von Herrschaftspraktiken als Raum- und Netzwerkpraktiken in der Frühen Neuzeit: Über die Parforcejagd wird das Wild zum Träger fürstlicher Herrschaft über ganze Territorien. Damit ist der Grundstein für eine lange noch gültige Praxis gelegt, sich durch das Schauspiel der Jagd als Souverän zu präsentieren – und ins Kreuzfeuer der Kritik zu geraten.
