description: Preeclampsia is one of the leading causes of maternal and fetal morbidity and mortality. The objective of our study was to study risk factors and complications associated with severe preeclampsia requiring intensive care unit (ICU) admission Retrospective comparative study over a period from 1st of January 2015 to 1st of January 2019 in the University’s maternity unit of South Reunion (Indian Ocean). Our sampling included all preeclamptic patients who delivered in the Southern part of the island. Patients admitted to intensive care unit (ICU) and those who remained in the maternity unit (controls) were reviewed. Out of 482 preeclampsia cases, 94 women (19.5%) needed a transfer in ICU, of which only 21 (4.3%) needed invasive intensive care. Mean length of stay was 2.4 ± 2.1 days. ICU admission was associated with HELLP syndrome (OR 8.5 [4.9–14.9], p<.001), severe post-partum hemorrhage (OR 5.86 [1.29–26.70], p=.01) and early onset of preeclampsia (<34 weeks gestation), 2.97 [1.9-4.7], p<.001), leading to higher rate of C-section (OR 2.83 [1.67–4.78], p<.001). There were three patients with a history of eclampsia and no case of maternal death was reported. Fetal prognosis was much poorer in maternal ICU admissions than in controls, with outcomes including lower birth weight (1776 vs. 2304 g, p<.001) and higher perinatal morbidity (infant respiratory distress syndrome 3.70 [1.94–7.05], p<.001) and mortality (<.001). Women needing invasive ICU represented 4.3% of preeclampsia cases. This experience is of interest for lower resource settings such as in countries like Madagascar where very intensive ICU means are very poor, but simpler ICU surveillance is possible. Fetal prognosis was poor though no maternal death was reported. Thus, a multidisciplinary approach of patients with preeclampsia should be encouraged; admission into ICU should be facilitated, as soon as any sign of severity and complications appears.

Visual literacy--Study and teaching

description: Visual Literacy is an area of study that has spawned varied theoretical writing, definitions, practical applications, and interdisciplinary insights over the past few decades in American education. In 2011 the Association of College & Research Libraries presented its Visual Literacy Competency Standards for Higher Education. The standards identify skills that students in the 21st century need to access, interpret, evaluate, and create meaningful images. This study interrogates if and how competency standards are used amongst academic librarians who work in art libraries, with data visualization, or who simply incorporate some aspect of visual literacy into their instruction sessions or research consultations. Conclusions are drawn from interviews with seven local academic librarians, and the author identifies major trends, as well as areas of disagreement, in visual literacy and is standardization in higher education.

description: There is significant debate over whether phase 1 pediatric oncology trials are ethical and approvable. We thus surveyed IRB members to answer four questions. First, do IRB members think the potential medical benefits of average phase 1 pediatric oncology trials justify the risks? Second, do they think these trials are ethically appropriate? Third, do they think these trials are approvable? Fourth, how do the views of IRB members on the first two questions compare to the views of the US public? Of the 80 respondents who answered the test questions correctly, 18.8% stated that the potential medical benefits of average phase 1 pediatric oncology trials outweigh the risks, 32.5% stated that the potential medical benefits and risks are about equal, and 48.8% stated that the risks outweigh the potential medical benefits. Compared to the general public, IRB members were significantly more likely to think the risks outweigh the potential medical benefits (p = 0.01). Finally, 68.8% of IRB members indicated that average phase 1 pediatric oncology trials are approvable, and 56.3% indicated that these trials are appropriate in children. These findings suggest two-thirds of IRB members believe average phase 1 pediatric oncology trials are approvable. Yet, almost half regard the risks as outweighing the potential medical benefits and almost half think these trials are inappropriate. These findings raise important questions regarding why IRB members and the general public evaluate the same risk/benefit profile differently, and whether it is possible to reconcile the two perspectives.

description: This study aimed to evaluate liver malformations and intrahepatic bile ductal ectasia and dilatation (IBDED) in cases of prenatal diagnosis of autosomal recessive polycystic kidney disease (ARPKD) using magnetic resonance imaging (MRI). This retrospective study involved 209 cases referred for fetal MRI studies (f-MRI) from March 2004 and December 2019, suspicious of congenital renal disease. Fetuses that met the criteria for ARPKD were selected. Six cases were diagnosed as ARPKD (2.8%). The median gestational age at MRI examination was 28 weeks (24–36 weeks). IBDED was observed in 84% of cases. Moreover, 66% presented multilobar liver lesions, and 33% exhibited monolobar lesions. The “central dot sign” (CDS) was found in half of the cases. In this case series of prenatal diagnosis of ARPKD using f-MRI, IBDED was present in the majority of the cases, and the CDS was noted in half of the cases.

description: The presence of an anterior mediastinal mass should prompt rapid triage, workup and treatment to effectively manage and prevent emergent complications. Implementation of an AMM protocol can ensure the response is standardized and coordinated. Importantly, such a protocol can encourage prompt multi-disciplinary communication to mitigate risks associated with procedures required for timely diagnosis. The aim of this review is to evaluate the BC Children’s Hospital’s Pediatric New/Suspected Anterior Mediastinal Mass (AMM) Protocol. Retrospective chart review was conducted for 18 patients admitted from February 2016 to May 2020 with AMM for whom the protocol was enacted. Primary parameters assessed presence of high-risk feature at time of presentation, time from admission and/or protocol activation to specific time points, including imaging, first diagnostic procedure, and diagnosis. Data regarding perioperative management, including anesthetic considerations and peri-operative complications, was also collected. Mean time from protocol activation to first diagnostic procedure and diagnosis were 1.88 days (range 0–7) and 2.24 days (range 0–7), respectively. The majority of procedures were conducted under sedation (n = 77, 64%), followed by general anesthetic (GA; n = 34, 28%) and local anesthetic (n = 10, 8%). Despite 15 cases having more than one high risk feature, pre-operative steroids were only administered for four of the total 158 procedures (3%) and extracorporeal life support (ECLS) and otolaryngology (ENT) were only required for immediate availability for seven procedures (4%). Furthermore, only 10 procedures (8%) had associated complications and none of these complications resulted in patient death. Our data demonstrate that implementation of a streamlined multi-disciplinary protocol can expedite time to diagnosis without impacting patient safety.

description: Improved miniaturization capabilities for complex fisheye camera systems have recently led to the introduction of many compact 360-degree cameras on the consumer technology market. Designed primarily for recreational photography, several manufacturers have decided to allow users access to raw imagery for further editing flexibility, thereby offering data at sensor level that can be directly exploited for absolute-light quantification. In this study, we demonstrate methodologies to carefully calibrate a consumer-grade 360-degree camera for radiometry use. The methods include linearity analysis, geometric calibration, assessment of the illumination fall-off across the image plane, spectral-response determination, absolute spectral-radiance calibration, immersion factor determination and dark-frame analysis. Accuracy of the calibration was validated by a real-world experiment comparing sky radiance measurements with a co-localized Compact Optical Profiling System (C-OPS, Biospherical Instruments Inc.), which gave mean unbiased percentage differences of less than 21.1 %. Using the photon-transfer technique, we calculated that this camera consisting of two fisheyes with a 182$^\circ$ field of view in air (152$^\circ$ in water) has a limit of detection of at least $4.6 \times 10^{-7}$ $\mathrm{W \cdot sr^{-1} \cdot m^{-2} \cdot nm^{-1}}$ in its three spectral channels. This technology, with properly stored calibration data, may benefit researchers from multiple scientific areas interested in radiometric geometric light-field study. While some of these radiometric calibration methods are complex or costly, this work opens up possibilities for easy-to-use, inexpensive, and accessible radiance cameras.

description: We analyse the behaviour of the spectrum of the system of Maxwell equations of electromagnetism, with rapidly oscillating periodic coefficients, subject to periodic boundary conditions on a "macroscopic" domain $(0,T)^d, T>0.$ We consider the case when the contrast between the values of the coefficients in different parts of their periodicity cell increases as the period of oscillations $η$ goes to zero. We show that the limit of the spectrum as $η\to0$ contains the spectrum of a "homogenised" system of equations that is solved by the limits of sequences of eigenfunctions of the original problem. We investigate the behaviour of this system and demonstrate phenomena not present in the scalar theory for polarised waves.

description: This study describes a latent content analysis of the deeds of gift currently used by  collecting repositories in the United States. The study was conducted to determine the  presence of a range of concepts related to digital materials and born-digital objects in a  collecting repository's deed of gift.  Nearly one-third of 80 deeds of gift discuss digital materials, yet only five repositories  currently address born-digital objects. Access to digital materials and digital preservation  activities are the concepts most likely to be addressed in deeds of gift, while the  specification of the repository as holder of the official research digital copy, the creation  of technical metadata, and method of capturing born-digital objects are among the  concepts least likely to be discussed. Data suggest longer deeds of gift are more likely to  address concepts related to digital materials and born-digital objects.
title: Route Optimization for take-out deliveries

description: The restaurant industry has long embraced technology, relying on POS and restocking platforms (i.e. virtual places which do not trade products but rather facilitate transactions between the supply market ends*) to leverage Web 2.0 apps and what comes along with it, like social media reviews (Yelp, Instagram) and ratings (TripAdvisor, e food etc.).
Now, once again, the food industry begins to capitalize on the rise of the Gig Economy (also called O2O, Sharing or On-Demand economy) and its reshaping forms, as every country is gradually evolving, adopting this new technologically-imposed culture. Millennials increasingly search for flexible, part-time work and, according to the National Restaurant Association, the restaurants industry (which is a big part of the App’s target market) has a notably higher percentage of part-time workers than the broader workforce.
This study reviews the existing literature and examines methods that sustain the optimization frameworks (usually referred to as platforms) that control the association between deliverers, goods and store owners in order to study ways to increase fairness and improve the working conditions of deliverers. Thus, as the title of the study suggests, the idea is to keep the Route Optimization Techniques per case, study the advantages and disadvantages that they bring to the table and advise for ways that a meritocratic but equal exploitation (fairness) of the emerging opportunities (here orders) can be beneficial (or marginally beneficial) to all actors, and especially the deliverers. For example, a deliverer nowadays works for a specific store (or branded fleet) sometimes distributing a specific set of goods, thus being restricted to work fixed hours at limited areas, receiving a limited salary. During the peak-hours the consumers anticipate the same quality of service which translates into stress for both the shop owners and the deliverers, especially now that the user-rating concept has been so immersive around transactions and more specifically, in this case, to the entirety of the food distribution process.
The proposition is rhetorically constructed to complementarily contribute to the solutions offered in the respective literature, by paying special care to the democratization of the medium as seen from the deliverer’s point of view, in order to allow for a fair and equal chance for meritocratic access to all available facilities, and thus any potential profit.
*  ends here refer to the consumer/customer/requester/client on the demand side and the company/firm/producer/ /provider/merchant/restaurant/owner/server on the supplier side. These two ends meet through the deliverer/delivery executive/courier/driver/rider/agent/fleet/vehicle of the mediator workforce platform (dispatcher/aggregator).

description: One of the components of natural language processing that has received a lot of investigation recently is semantic textual similarity. In computational linguistics and natural language processing, assessing the semantic similarity of words, phrases, paragraphs, and texts is crucial. Calculating the degree of semantic resemblance between two textual pieces, paragraphs, or phrases provided in both monolingual and cross-lingual versions is known as semantic similarity. Cross lingual semantic similarity requires corpora in which there are sentence pairs in both the source and target languages with a degree of semantic similarity between them. Many existing cross lingual semantic similarity models use a machine translation due to the unavailability of cross lingual semantic similarity dataset, which the propagation of the machine translation error reduces the accuracy of the model. On the other hand, when we want to use semantic similarity features for machine translation the same machine translations should not be used for semantic similarity. For Persian, which is one of the low resource languages, no effort has been made in this regard and the need for a model that can understand the context of two languages is felt more than ever. In this article, the corpus of semantic textual similarity between sentences in Persian and English languages has been produced for the first time by using linguistic experts. We named this dataset PESTS (Persian English Semantic Textual Similarity). This corpus contains 5375 sentence pairs. Also, different models based on transformers have been fine-tuned using this dataset. The results show that using the PESTS dataset, the Pearson correlation of the XLM ROBERTa model increases from 85.87% to 95.62%.

description: We investigated coupled-qubit-based thermal machines powered by quantum measurements and feedback. We considered two different versions of the machine: (1) a quantum Maxwell’s demon, where the coupled-qubit system is connected to a detachable single shared bath, and (2) a measurement-assisted refrigerator, where the coupled-qubit system is in contact with a hot and cold bath. In the quantum Maxwell’s demon case, we discuss both discrete and continuous measurements. We found that the power output from a single qubit-based device can be improved by coupling it to the second qubit. We further found that the simultaneous measurement of both qubits can produce higher net heat extraction compared to two setups operated in parallel where only single-qubit measurements are performed. In the refrigerator case, we used continuous measurement and unitary operations to power the coupled-qubit-based refrigerator. We found that the cooling power of a refrigerator operated with swap operations can be enhanced by performing suitable measurements.

description: Structural imperfections, heteroatom dopants, and the interconnected pore structure of carbon materials have a huge impact on their electrochemical performance in lithium-ion and sodium-ion batteries due to the specific ion transport and the dominant storage mechanism at surface defect sites. In this work, mesopore-enriched nitrogen-doped carbon (NC) materials were produced with template-assisted chemical vapor deposition using calcium tartrate as the template precursor and acetonitrile as the carbon and nitrogen source. The chemical states of nitrogen, the volume of mesopores, and the specific surface areas of the materials were regulated by adjusting the synthesis temperature. The electrochemical testing of NC materials synthesized at 650, 750, and 850 °C revealed the best performance of the NC-650 sample, which was able to deliver 182 mA·h·g−1 in sodium-ion batteries and 1158 mA·h·g−1 in lithium-ion batteries at a current density of 0.05 A·g−1. Our study shows the role of defect sites, including carbon monovacancies and nitrogen-terminated vacancies, in the binding and accumulation of sodium. The results provide a strategy for managing the carbon structure and nitrogen states to achieve a high alkali-metal-ion storage capacity and long cycling stability, thereby facilitating the electrochemical application of NC materials.

description: We investigate N$_f$ = 1 QCD in external magnetic fields on the lattice. The background field is introduced by means of the so-called Schrodinger functional. We adopt standard staggered fermions with constant bare mass $am = 0.025$ and magnetic fields with constant magnetic flux up to $a^2 e H \simeq 2.3562$. We find that the the deconfinement and chiral symmetry restoration temperatures do not depend on the strength of the applied magnetic field. Our method allow us to easily study the effects of the external magnetic fields on the QCD thermodynamics. We determine the influences of applied magnetic fields to the free energy, pressure, and equation of state of strongly interacting matter.

description: Background: The COVID-19 pandemic is a health emergency resulting in multiple stressors that may be related to posttraumatic stress disorder (PTSD). Objective: This study examined relationships between risk and protective factors, pandemic-related stressors, and PTSD during the COVID-19 pandemic. Methods: Data from the European Society of Traumatic Stress Studies (ESTSS) ADJUST Study were used. N = 4,607 trauma-exposed participants aged 18 years and above were recruited from the general populations of eleven countries (Austria, Croatia, Georgia, Germany, Greece, Italy, Lithuania, the Netherlands, Poland, Portugal, and Sweden) from June to November 2020. We assessed sociodemographic (e.g. gender), pandemic-related (e.g. news consumption), and health-related (e.g. general health condition) risk and protective factors, pandemic-related stressors (e.g. fear of infection), and probable PTSD (PC-PTSD-5). The relationships between these variables were examined using logistic regression on multiple imputed data sets. Results: The prevalence of probable PTSD was 17.7%. Factors associated with an increased risk for PTSD were younger age, female gender, more than 3 h of daily pandemic-related news consumption (vs. no consumption), a satisfactory, poor, or very poor health condition (vs. a very good condition), a current or previous diagnosis of a mental disorder, and trauma exposure during the COVID-19 pandemic. Factors associated with a reduced risk for PTSD included a medium and high income (vs. very low income), face-to-face contact less than once a week or 3–7 times a week (vs. no contact), and digital social contact less than once a week or 1–7 days a week (vs. no contact). Pandemic-related stressors associated with an increased risk for PTSD included governmental crisis management and communication, restricted resources, restricted social contact, and difficult housing conditions. Conclusion: We identified risk and protective factors as well as stressors that may help identify trauma-exposed individuals at risk for PTSD, enabling more efficient and rapid access to care.

description: Purpose of Review Individuals with personality disorders are frequently seen in mental health settings. Their symptoms typically reflect a high level of suffering and burden of disease, with potentially harmful societal consequences, including costs related to absenteeism at work, high use of health services, ineffective or harmful parenting, substance use, suicidal and non-suicidal self-harming behavior, and aggressiveness with legal consequences. Psychotherapy is currently the first-line treatment for patients with personality disorders, but the study of psychotherapy in the domain of personality disorders faces specific challenges. Recent Findings Challenges include knowing what works for whom, identifying which putative mechanisms of change explain therapeutic effects, and including the social interaction context of patients with a personality disorder. By following a dimensional approach, psychotherapy research on personality disorders may serve as a model for the development and study of innovative psychotherapeutic interventions. Summary We recommend developing the following: (a) an evidence base to make treatment decisions based on individual features; (b) a data-driven approach to predictors, moderators, and mechanisms of change in psychotherapy; (c) methods for studying the interaction between social context and psychotherapy.

description: In numerous contexts, including community question answering systems, school exams, and trivia competitions, a need to assess the difficulty of questions arises. This study examines what features predict difficulty in the realm of trivia questions, considering features related to readability and the question's topic as potential contributors. Using clues from the game show Jeopardy!, the study finds that features relating to a trivia question's length, the inclusion of audiovisual media, and its constituent noun and verb phrases have a significant impact on the clue's difficulty. Based on these findings, this study proposes that finding more nuanced ways to depict the amount of information in a trivia question would lead to further advancements.

description: The interference of non-classical states of light enables quantum-enhanced applications reaching from metrology to computation. Most commonly, the polarisation or spatial location of single photons are used as addressable degrees-of-freedom for turning these applications into praxis. However, the scale-up for the processing of a large number of photons of such architectures is very resource demanding due to the rapidily increasing number of components, such as optical elements, photon sources and detectors. Here we demonstrate a resource-efficient architecture for multi-photon processing based on time-bin encoding in a single spatial mode. We employ an efficient quantum dot single-photon source, and a fast programmable time-bin interferometer, to observe the interference of up to 8 photons in 16 modes, all recorded only with one detector--thus considerably reducing the physical overhead previously needed for achieving equivalent tasks. Our results can form the basis for a future universal photonics quantum processor operating in a single spatial mode.

description: Sphingolipids are crucial molecules of the mammalian epidermis. The formation of skin-specific ceramides contributes to the formation of lipid lamellae, which are important for the protection of the epidermis from excessive water loss and protect the skin from the invasion of pathogens and the penetration of xenobiotics. In addition to being structural constituents of the epidermal layer, sphingolipids are also key signaling molecules that participate in the regulation of epidermal cells and the immune cells of the skin. While the importance of ceramides with regard to the proliferation and differentiation of skin cells has been known for a long time, it has emerged in recent years that the sphingolipid sphingosine 1-phosphate (S1P) is also involved in processes such as the proliferation and differentiation of keratinocytes. In addition, the immunomodulatory role of this sphingolipid species is becoming increasingly apparent. This is significant as S1P mediates a variety of its actions via G-protein coupled receptors. It is, therefore, not surprising that dysregulation in the signaling pathways of S1P is involved in the pathophysiological conditions of skin diseases. In the present review, the importance of S1P in skin cells, as well as the immune cells of the skin, is elaborated. In particular, the role of the molecule in inflammatory skin diseases will be discussed. This is important because interfering with S1P signaling pathways may represent an innovative option for the treatment of inflammatory skin diseases.

description: We show that the Galactic latitude distribution of IceCube astrophysical neutrino events with energies above 100~TeV is inconsistent with the isotropic model of the astrophysical neutrino flux. Namely, the Galactic latitude distribution of the events shows an excess at low latitudes |b|<10 degrees and a deficit at high Galactic latitude |b|> 50 degrees. We use Monte-Carlo simulations to show that the inconsistency of the isotropic signal model with the data is at > 3 sigma level, after the account of trial factors related to the choice of the low-energy threshold and Galactic latitude binning in our analysis.

A content analysis of the back of the book indexes of hymnals of the Baptist, Episcopal and Methodist denominations in the United States

description: This paper documents the content analysis of back of the book indexes of selected Methodist, Episcopal and Baptist denominational hymnals published between 1801 and 1996 and designated for use by these American congregations.  The study was conducted to ascertain if any denominational and chronological trends in the indexing of these hymnals exist; if so, to determine what they are, the significance of these differences, to speculate on the reasons these differences exist and to explore the ramifications of these differences to the fields of hymnology and information science. An important historical discovery was that metrical and alphabetical tune indexes appeared at the same time that scores began to be included in hymnals (1855).  Additionally, although the three denominations share more than half the contents of their individual hymnbooks, each group favors a particular set of indexes.
Binomial Cayley Graphs and Applications to Dynamics on Finite Spaces

description: Binomial Cayley graphs are obtained by considering the binomial coefficient of the weight function of a given Cayley graph and a natural number. We introduce these objects and study two families: one associated with symmetric groups and the other with powers of cyclic groups. We determine various combinatorial properties of these graphs through the spectral analysis of their adjacency matrices. In the case of symmetric groups, we establish a relation between the multiplicity of the null eigenvalue and longest increasing sub-sequences of permutations by means of the RSK correspondence. Finally, we consider dynamical arrangements of finitely many elements in finite spaces, which we refer to as particle-box systems. We apply the results obtained on binomial Cayley graphs in order to describe their degeneracy.

description: This study is a latent content analysis of nine young adult novels that explore the world of suicide among adolescents.  The analysis consisted of identifying the risk factors that have been documented by amny psychological studies and determining whether the factors fit the victim's suicidal circumstances.  From the documented studies, 25 risk factors were identified.  The novels were then analyzed to show evidence of any risk factors involved, with pertinent passages noted in the analysis.  Of the nine novels analyzed, each showed from three to eight risk factors present that contributed to the adolescent's decision to commit suicide.  The risk factors were usually obvious, but often ignored by family and friends.  There is a need for these factors to be recognized by those that can provide help, and yound adult fiction is one way to provide help.  It is up to our libraries to keep our adolescents connected to these books, to provide current information, and to provide interesting novels that concern real-life situations that may help avoid a decision that may be life threatening.

description: The ability to sense the magnetic state of individual magnetic nano-objects is a key capability for powerful applications ranging from readout of ultra-dense magnetic memory to the measurement of spins in complex structures with nanometer precision. Magnetic nano-objects require extremely sensitive sensors and detection methods. Here we create an atomic spin sensor consisting of three Fe atoms and show that it can detect nanoscale antiferromagnets through minute surface-mediated magnetic interaction. Coupling, even to an object with no net spin and having vanishing dipolar stray field, modifies the transition matrix element between two spin states of the Fe-atom-based spin sensor that changes the sensor's spin relaxation time. The sensor can detect nanoscale antiferromagnets at up to three nanometers distance and achieves an energy resolution of 10 micro-electronvolts surpassing the thermal limit of conventional scanning probe spectroscopy. This scheme permits simultaneous sensing of multiple antiferromagnets with a single spin sensor integrated onto the surface.

description: Using nonrelativistic QCD (NRQCD) factorization, we calculate the yields for $J/ψ$, $ψ(2S)$ and $Υ(1S)$ hadroproduction at $\sqrt{s}=$ 72 GeV and 115 GeV including the next-to-leading order QCD corrections. Both these center-of-mass energies correspond to those obtained with 7~TeV and 2.76~TeV nucleon beam impinging a fixed target. We study the cross section integrated in $p_t$ as a function of the rapidity as well as the $p_t$ differential cross section in the central rapidity region. Using different NLO fit results of the NRQCD long-distance matrix elements, we evaluate a theoretical uncertainty which is certainly much larger than the projected experimental uncertainties with the expected 20 fb$^{-1}$ to be collected per year with AFTER@LHC.

description: Full-sky maps of the cosmic microwave background temperature reveal a 7% asymmetry of fluctuation power between two halves of the sky. A common phenomenological model for this asymmetry is an overall dipole modulation of statistically isotropic fluctuations, which produces particular off-diagonal correlations between multipole coefficients. We compute these correlations and construct corresponding estimators for the amplitude and direction of the dipole modulation. Applying these estimators to various cut-sky temperature maps from Planck and WMAP data shows consistency with a dipole modulation, differing from a null signal at 2.5$σ$, with an amplitude and direction consistent with previous fits based on the temperature fluctuation power. The signal is scale dependent, with a statistically significant amplitude at angular scales larger than 2 degrees. Future measurements of microwave background polarization and gravitational lensing can increase the significance of the signal. If the signal is not a statistical fluke in an isotropic Universe, it requires new physics beyond the standard model of cosmology.
