description: Tables are widely used in several types of documents since they can bring important information in a structured way. In scientific papers, tables can sum up novel discoveries and summarize experimental results, making the research comparable and easily understandable by scholars. Several methods perform table analysis working on document images, losing useful information during the conversion from the PDF files since OCR tools can be prone to recognition errors, in particular for text inside tables. The main contribution of this work is to tackle the problem of table extraction, exploiting Graph Neural Networks. Node features are enriched with suitably designed representation embeddings. These representations help to better distinguish not only tables from the other parts of the paper, but also table cells from table headers. We experimentally evaluated the proposed approach on a new dataset obtained by merging the information provided in the PubLayNet and PubTables-1M datasets.

description: Objective: The use of speech measures is becoming a common practice in the assessment of bulbar disease progression in amyotrophic lateral sclerosis (ALS). This study aimed to establish psychometric properties (e.g. reliability, validity, sensitivity, specificity) of speech and pause timing measures during a standardized passage. Methods: A large number of passage recordings (ALS N = 775; Neurotypical controls N = 323) was analyzed using a semi-automatic method (Speech and Pause Analysis, SPA). Results: The results revealed acceptable reliability of the speech and pause measures across repeated recording by the control participants. Strong construct validity was established via significant group differences between patients and controls and correlation statistics with clinical measures of overall ALS and bulbar disease severity. Speaking rate, pause events, and mean pause duration were able to detect ALS participants at the presymptomatic stage of bulbar disease with a good discrimination ability (AUC 0.81). Conclusions: Based on the current psychometric evaluation, performing passage recording and speech and pause timing analysis was deemed useful for detecting early and progressive changes associated with bulbar ALS.

description: Tables are widely used in documents because of their compact and structured representation of information. In particular, in scientific papers, tables can sum up novel discoveries and summarize experimental results, making the research comparable and easily understandable by scholars. Since the layout of tables is highly variable, it would be useful to interpret their content and classify them into categories. This could be helpful to directly extract information from scientific papers, for instance comparing performance of some models given their paper result tables. In this work, we address the classification of tables using a Graph Neural Network, exploiting the table structure for the message passing algorithm in use. We evaluate our model on a subset of the Tab2Know dataset. Since it contains few examples manually annotated, we propose data augmentation techniques directly on the table graph structures. We achieve promising preliminary results, proposing a data augmentation method suitable for graph-based table representation.

description: One of the practical ways to overcome the adverse environmental effects of plastic bottle waste is to implement bottles into concrete, one of the most widely used materials in the construction industry. Plastic bottles are mainly made of polyethylene terephthalate (PET) and can be used as a fiber to reinforce concrete. In recent years, PET fiber-reinforced concrete (PFRC) has attracted researcher attention, and several experimental studies have been conducted. This paper aims to present the benefits of using PET fiber as a reinforcing element in concrete using a machine learning approach. By considering the effect of PET fibers in concrete, engineers and stakeholders may be encouraged to further use these recycled materials.

description: Congenital cardiac and neurodevelopmental deficits have been recently linked to the mediator complex subunit 13-like protein MED13L, a subunit of the CDK8-associated mediator complex that functions in transcriptional regulation through DNA-binding transcription factors and RNA polymerase II. Heterozygous MED13L variants cause transposition of the great arteries and intellectual disability (ID). Here, we report eight patients with predominantly novel MED13L variants who lack such complex congenital heart malformations. Rather, they depict a syndromic form of ID characterized by facial dysmorphism, ID, speech impairment, motor developmental delay with muscular hypotonia and behavioral difficulties. We thereby define a novel syndrome and significantly broaden the clinical spectrum associated with MED13L variants. A prominent feature of the MED13L neurocognitive presentation is profound language impairment, often in combination with articulatory deficits.

description: Let X be a separated scheme of finite type over a field k and D a non-reduced effective Cartier divisor on it. We attach to the pair (X, D) a cycle complex with modulus, whose homotopy groups - called higher Chow groups with modulus - generalize additive higher Chow groups of Bloch-Esnault, Rülling, Park and Krishna-Levine, and that sheafified on $X_{Zar}$ gives a candidate definition for a relative motivic complex of the pair, that we compute in weight 1. When X is smooth over k and D is such that $D_{red}$ is a normal crossing divisor, we construct a fundamental class in the cohomology of relative differentials for a cycle satisfying the modulus condition, refining El-Zein's explicit construction. This is used to define a natural regulator map from the relative motivic complex of (X,D) to the relative de Rham complex. When X is defined over $\mathbb{C}$, the same method leads to the construction of a regulator map to a relative version of Deligne cohomology, generalizing Bloch's regulator from higher Chow groups. Finally, when X is moreover connected and proper over $\mathbb{C}$, we use relative Deligne cohomology to define relative intermediate Jacobians with modulus $J^r_{X|D}$ of the pair (X,D). For r= dim X, we show that $J^r_{X|D}$ is the universal regular quotient of the Chow group of 0-cycles with modulus.

description: The high-Reynolds number stratified wake of a slender body is studied using a high-resolution hybrid simulation. The wake generator is a 6:1 prolate spheroid with a tripped boundary layer, the diameter-based body Reynolds number is $Re= U_\infty D/ν= 10^5$, and the body Froude numbers are $Fr=U_\infty/ND=\{2,10,\infty\}$. The wake defect velocity ($U_d$) decays following three stages with different wake decay rates \citep{Spedding1997} as for a bluff body. However, the transition points among stages do not follow the expected $Nt = Nx/U_\infty$ values. Comparison with the wake of a circular disk in similar conditions \citep{Chongsiripinyo2020} quantifies the influence of the wake generator - bluff versus slender - in stratified flow. The strongly stratified $Fr=2$ wake is in a resonant state. The steady lee waves strongly modulate the mean flow and, relative to the disk, the $Fr=2$ spheroid wake shows an earlier transition from the non-equilibrium (NEQ) stage to the quasi-two-dimensional (Q2D) stage. The NEQ-Q2D transition is followed by a sharp increase in the turbulent kinetic energy and horizontal wake meanders. At $Fr=10$, the start of the NEQ stage is delayed. Transfers between kinetic energy and potential energy reservoirs (both mean and turbulence) are analyzed and the flows are compared in phase space (local Froude and Reynolds number as coordinates). Overall, the results of this study point to the difficulty of finding a universal framework for stratified wake evolution, independent of the features of the body, and provide insights into how buoyancy effects depend on the wake generator.

description: Efficiently finding similar segments or motifs in time series data is a fundamental task that, due to the ubiquity of these data, is present in a wide range of domains and situations. Because of this, countless solutions have been devised but, to date, none of them seems to be fully satisfactory and flexible. In this article, we propose an innovative standpoint and present a solution coming from it: an anytime multimodal optimization algorithm for time series motif discovery based on particle swarms. By considering data from a variety of domains, we show that this solution is extremely competitive when compared to the state-of-the-art, obtaining comparable motifs in considerably less time using minimal memory. In addition, we show that it is robust to different implementation choices and see that it offers an unprecedented degree of flexibility with regard to the task. All these qualities make the presented solution stand out as one of the most prominent candidates for motif discovery in long time series streams. Besides, we believe the proposed standpoint can be exploited in further time series analysis and mining tasks, widening the scope of research and potentially yielding novel effective solutions.

Designing a landscape bench

Publisher: name: No Publisher Supplied

description: The built landscape that ranges from the paved concrete paths that we walk on to the towering buildings that can rise thousands of feet above. These objects were intentionally designed by people to serve specific functions to benefit us. However, as time moves forward, and we as people change, our designs can become outdated, no longer relevant, or simply not exciting. The landscape bench is one part of the landscape that has struggled to evolve over the years and is limited in the number of functions that it could provide. The landscape bench has been documented for hundreds of years and has served as a place of refuge in the landscape - providing a hub for social interaction, a location to go to, and simply a place to sit. Our current perception and expectations have limited this piece of the landscape to just a place to sit, not allowing for even simple changes to its simple design. Through the design and build process this thesis investigates topics regarding material sustainability, site specific designs, and social interactions in relation to bench design and construction. Through the creation of a prototype and a final model this project created a well researched and designed bench for its site. The process demonstrated that making considerations for history, sustainability and case studies, the landscape bench can be designed and built with meaning and purpose.

description: The dual-specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A) gene, located on chromosome 21q22.13 within the Down syndrome critical region, has been implicated in syndromic intellectual disability associated with Down syndrome and autism. DYRK1A has a critical role in brain growth and development primarily by regulating cell proliferation, neurogenesis, neuronal plasticity and survival. Several patients have been reported with chromosome 21 aberrations such as partial monosomy, involving multiple genes including DYRK1A. In addition, seven other individuals have been described with chromosomal rearrangements, intragenic deletions or truncating mutations that disrupt specifically DYRK1A. Most of these patients have microcephaly and all have significant intellectual disability. In the present study, we report 10 unrelated individuals with DYRK1A-associated intellectual disability (ID) who display a recurrent pattern of clinical manifestations including primary or acquired microcephaly, ID ranging from mild to severe, speech delay or absence, seizures, autism, motor delay, deep-set eyes, poor feeding and poor weight gain. We identified unique truncating and non-synonymous mutations (three nonsense, four frameshift and two missense) in DYRK1A in nine patients and a large chromosomal deletion that encompassed DYRK1A in one patient. On the basis of increasing identification of mutations in DYRK1A, we suggest that this gene be considered potentially causative in patients presenting with ID, primary or acquired microcephaly, feeding problems and absent or delayed speech with or without seizures.

description: CD8 plays an important role in the activity of cytolytic T cells (CTL). However, whether or not CD8 is required for the development of CTL has not been clearly determined. Cytotoxic activity in the CD8α knockout mouse is difficult to induce, and has only been demonstrated against allogenic MHC targets. The lack of cytotoxicity may result from impaired lineage commitment of CTL in the absence of CD8, or diminished competitiveness during selection against (unimpaired) development of CD4+ T cells on MHC II. To differentiate between these possibilities, we have generated a double knockout mouse, CD8α-/- × MHC II-/- (II-/8-). In II-/8- mice, developing MHC I-reactive thymocytes cannot rely upon CD8 for selection, but they also cannot be overwhelmed by efficient selection of MHC II-reactive thymocytes. In this mouse, a large, heterogeneous population of peripheral coreceptor double negative (DN) and CD4 positive T cells develops. Peripheral DN T cells are fully functional CTL. They display cytolytic activity against allogeneic MHC, and against syngeneic MHC following LCMV infection. Cells from LCMV-infected mice bind more MHC I tetramer at lower concentrations than their wild type CTL counterparts. These results demonstrate unequivocally that CD8 is not required for commitment of thymocytes to the CTL lineage.
Applications of Urban Informatics in Sustainability Planning for Food Waste Management

description: A lack of sustainability metrics for cities, mainly due to data constraints and inadequate awareness, hinders rational, communicative, and inclusive sustainability planning processes. Urban informatics (UI) is identified as a promising solution to these problems. This study aims to answer the central question: how could urban informatics advance data-driven and evidence-based processes for effective, equitable sustainability planning? By focusing on sustainable food waste management (FWM), the numerical analysis first tackles data constraints through UI. This study establishes the first household-level food waste inventory database (HFWID) that quantitatively characterizes food waste generation (e.g., by locations and types of food waste) at the household level. The data is further used to evaluate food waste characterization at the regional level and assess potential environmental impacts. The results highlight that various assessment metrics can lead to various policy implications; it suggests planners should engage with the public to ensure inclusive planning processes from analysis to implementation. The follow-up study, building upon HFWID, identifies influential factors of residential food waste generation that have been understudied. The findings suggest that policies that do not take socio-demographic factors into account may lead to unintended penalties; built environments, such as walkable accessibility to grocery stores, can also affect residential food waste generation. These findings urge planners to consider community characteristics, land uses, and urban form within a holistic framework for sustainable FWM. The third analysis integrates the findings from the first two studies and employs interdisciplinary methods to evaluate the sustainability of urban food recovery programs. It demonstrates that UI empowers scenario planning to better understand urban system dynamics, identify key factors of program performance, and communicate trade-offs of planning objectives. In summary, this dissertation research concludes that UI benefits sustainability planning by enriching urban research and sustainability planning data, improving analytics for effective communications, and informing collective decisions. The interdisciplinary approaches enable system-thinking to balance social, economic, and environmental objectives. Moreover, this study suggests that planning education should equip future planners to understand, implement, and advance UI applications as well as embrace cross-disciplinary learning and collaboration in dealing with urban sustainability challenges.

description: The dissipative dynamics of a quantum bistable system coupled to a Ohmic heat bath is investigated beyond the spin-boson approximation. Within the path-integral approach to quantum dissipation, we propose an approximation scheme which exploits the separation of time scales between intra- and interwell (tunneling) dynamics. The resulting generalized master equation for the populations in a space localized basis enables us to investigate a wide range of temperatures and system-environment coupling strengths. A phase diagram in the coupling-temperature space is provided to give a comprehensive account of the different dynamical regimes.

description: Objective: Angiogenin (ANG) is a pro-angiogenic and neurotrophic factor with an important role in stress-induced injury, by promoting neovascularization and neuronal survival. Identification of loss-of-function mutations and evidence of beneficial effect of ANG administration in transgenic SOD1G93A mice have linked ANG to the pathogenesis of Amyotrophic Lateral Sclerosis (ALS), stimulating interest in considering circulating ANG levels as an ALS disease biomarker although robust evidence is still lacking. Aim of our study was to assess differences of ANG levels in the cerebrospinal fluid (CSF) of a large cohort of patients with ALS and frontotemporal dementia (FTD) compared to controls and to explore correlations between ANG content and disease-related clinical variables. Methods: ANG levels were measured in CSF samples using a commercially available ELISA kit in 88 patients affected with ALS and/or FTD and 46 unrelated individuals (control group). Results: ANG levels didn’t differ significantly between cases and controls. Patients with FTD or ALS-FTD showed significantly increased CSF concentration of ANG compared to ALS patients without dementia and controls in a multivariate regression model (p < 0.001). No correlations were found in ALS/FTD patients between ANG levels and clinical parameters, including age, presence of C9orf72 repeat expansion, body mass index (BMI). Conclusions: our findings highlight a role of ANG as CSF biomarker useful to identify ALS patients with concurrent FTD and suggest that it should be further explored as potential biomarker for FTD.

description: Micro-RNA (miR) are increasingly recognized as critical regulators of tissue-specific patterns of gene expression. CD4+ T cells lacking miR-155, for example, exhibit bias towards Th2 differentiation, indicating that the absence of individual miR could alter CD4+ T cell differentiation. We now show that MiR-155 is induced upon T cell activation and that it promotes Th1 differentiation when over-expressed in activated CD4+ T cells. Antagonism of miR-155 leads to induction of IFN-γRα, and a functional miR-155 target site is identified within the 3′ UTR of IFN-γRα. These results identify IFN-γRα as a second miR-155 target in T cells and suggest that miR-155 contributes to Th1 differentiation in CD4+ T cells by inhibiting IFN-γ signaling.

description: Planetary transits detected by the CoRoT mission can be mimicked by a low-mass star in orbit around a giant star. Spectral classification helps to identify the giant stars and also early-type stars which are often excluded from further follow-up. We study the potential and the limitations of low-resolution spectroscopy to improve the photometric spectral types of CoRoT candidates. In particular, we want to study the influence of the signal-to-noise ratio (SNR) of the target spectrum in a quantitative way. We built an own template library and investigate whether a template library from the literature is able to reproduce the classifications. Including previous photometric estimates, we show how the additional spectroscopic information improves the constraints on spectral type. Low-resolution spectroscopy ($R\approx$1000) of 42 CoRoT targets covering a wide range in SNR (1-437) and of 149 templates was obtained in 2012-2013 with the Nasmyth spectrograph at the Tautenburg 2m telescope. Spectral types have been derived automatically by comparing with the observed template spectra. The classification has been repeated with the external CFLIB library. The spectral class obtained with the external library agrees within a few sub-classes when the target spectrum has a SNR of about 100 at least. While the photometric spectral type can deviate by an entire spectral class, the photometric luminosity classification is as close as a spectroscopic classification with the external library. A low SNR of the target spectrum limits the attainable accuracy of classification more strongly than the use of external templates or photometry. Furthermore we found that low-resolution reconnaissance spectroscopy ensures that good planet candidates are kept that would otherwise be discarded based on photometric spectral type alone.

DESIGNING AGORA: A SHARED MULTI-USER PROGRAMMING ENVIRONMENT

Publisher: name: Purdue University Graduate School

Subjects: Programming languages

description: Shared programming systems typically fall into one of two categories: systems to distribute code between users, and systems to allow shared access to editing or debugging facilities. Version-control systems allow distribution of code and are often more than adequate for large-scale software development occurring over a long period of time, but they can become unwieldy for fast iterative or exploratory development in which multiple users wish to participate. In these situations, shared editors or pair programming tools may suffice,with the caveat that any user of the system can typically modify any of the code at will. Rather than connecting several users to the same editor session, it would be more effective to allow users to maintain separate sessions while quickly sharing selected chunks of code at will. To enable this paradigm, we have designed a new interpreter to allow distributed users to selectively share code and data at run-time. Our solution consists of a bytecode virtual machine back-end with access to a shared environment and a management mechanism to control creation and usage of these resources. By providing access to interpreter sessions overa network connection, we do not tie our interpreter to executing code from any one particular programming language, allowing any conforming front-end compiler and user interface to be used. This solution allows the development burden of shared programs to be distributed dynamically between users at run-time through the shared environment while still affording control over what and when to share, thereby facilitating more effective incremental or experimental multi-user programming.

description: An increasing number of measurements in fundamental and applied physics rely on magnetically shielded environments with sub nano-Tesla residual magnetic fields. State of the art magnetically shielded rooms (MSRs) consist of up to seven layers of high permeability materials in combination with highly conductive shields. Proper magnetic equilibration is crucial to obtain such low magnetic fields with small gradients in any MSR. Here we report on a scheme to magnetically equilibrate MSRs with a 10 times reduced duration of the magnetic equilibration sequence and a significantly lower magnetic field with improved homogeneity. For the search of the neutron's electric dipole moment, our finding corresponds to a linear improvement in the systematic reach and a 40 % improvement of the statistical reach of the measurement. However, this versatile procedure can improve the performance of any MSR for any application.

description: Objectives: People with motor neurone disease (pwMND) experience communication impairments due to speech and motor dysfunction. Communication support in the form of Augmentative and Alternative Communication (AAC) in conjunction with Assistive Technology (AT) access methods are available, however, variation in provision care pathways exists across Scotland. We conducted a baseline study of communication support for pwMND in Scotland to inform and improve future service provision. Methods: A cross-sectional population-based study was undertaken. Anonymised demographic and clinical phenotypic data for all pwMND in Scotland were extracted from the Care Audit Research Evaluation of MND (CARE-MND) platform, the National MND Register for Scotland. Additional information for AT loans was provided by the third sector charitable organization MND Scotland (MNDS). Results: In total, 371 pwMND were included, 43% of all pwMND were recorded as having impaired speech (recent ALSFRS-R score assessment ≤3) and 69% had been referred to Speech and Language Therapist (SLT) services, although there was variation in referral time from diagnosis date. AAC equipment had been acquired by 17.3% of all pwMND; most commonly iPads and the LightwriterTM speech generating device. Conclusions: Our data highlight a high prevalence of speech impairment in pwMND irrespective of the subtype diagnosis. We therefore recommend standardized care pathways and earlier access to coordinated SLT and Occupational Therapist services to enable prospective and personalized decision making. Our findings further highlight the need for qualitative research to understand the preferences and impact of such interventions from the perspective of the user and their communication partners.

description: IL-2 plays a critical role in the induction and maintenance of FoxP3-expressing regulatory T cells (FoxP3+Treg). Reduced expression of IL-2 is linked to T cell-mediated autoimmune diseases such as Type 1 diabetes (T1D), in which an imbalance between FoxP3+Treg and pathogenic T effectors exists. We investigated the contribution of IL-2 to dysregulation of FoxP3+Treg by comparing wildtype NOD mice with animals congenic for a C57BL/6-derived disease resistant Il2 allele and in which T cell secretion of IL-2 is increased (NOD.B6Idd3). Whereas NOD mice exhibited a progressive decline in the frequency of CD62LHIFoxP3+Treg due to an increase in CD62LLOFoxP3+Treg, CD62LHIFoxP3+Treg were maintained in the pancreatic lymph nodes and islets of NOD.B6Idd3 mice. Notably, the frequency of proliferating CD62LHIFoxP3+Treg was elevated in the islets of NOD.B6Idd3 versus NOD mice. Increasing levels of IL-2 in vivo also resulted in larger numbers of CD62LHIFoxP3+Treg in NOD mice. These results demonstrate that IL-2 influences the suppressor activity of the FoxP3+Treg pool by regulating the balance between CD62LLO and CD62LHI FoxP3+Treg. In NOD mice reduced IL-2 expression leads to an increase in nonsuppressive CD62LLOFoxP3+Treg, which in turn correlates with a pool of CD62LHIFoxP3+Treg with limited proliferation.

description: We document the first occurrence of Sigmodontinae (Mammalia, Rodentia, Cricetidae) from the Pliocene of northern South America, from the San Gregorio Formation of northwestern Venezuela. The recovered isolated molars are identified as Oligoryzomys sp. and Zygodontomys sp., two currently widespread sigmodontines in South America. These records constitute the oldest representatives of these genera, potentially new species, and the first Pliocene occurrence for Oryzomyini and the whole subfamily outside Argentina. Hypotheses on the historical biogeography of sigmodontines have been constructed almost exclusively using genetic data and the fossils we report provide a new kind of evidence. The occurrence of Oligoryzomys sp. and Zygodontomys sp. in Venezuela provides novel information for the diversification models suggested for Oligoryzomys, by supporting a potential eastern corridor of open environments from northern to southern South America. The presence of sigmodontines from the locality home of the new reports, Norte Casa Chiguaje, is consistent with the palaeoenvironmental conditions originally proposed for it based on mammals and botanical records, being characterized as mixed open grassland/forest areas surrounding permanent freshwater systems. The new sigmodontine evidence is used to discuss the putative scenarios of the ancient evolution of the subfamily in South America, favouring a model in which open areas (savannahs) to the east of the Andes played crucial role aiding or obstructing Late Miocene–Pliocene sigmodontine dispersion southwards.

description: This thesis analyzes the voices and appeals used in conspiracy rhetoric which is distributed via the internet. The voices, one measure of the argument's authority, are analyzed and described in depth, with eleven voices identified. These voices and their significance to Condit's text as a whole are discussed. Following the voice analysis, an Aristotelian analysis of the text's appeals to ethos, logos, and pathos is performed to examine the persuasive force of Condit's argument. Finally, the correlation between the voices and the appeals is examined to determine the strength of the correlation between the two constructs and to determine whether each voice used appropriate appeals.
The Effects of Secondhand Smoke Exposure on Early Childhood Caries

description: Purpose: The purpose of this study was to determine the association between exposure to secondhand smoke and dental caries in an infant population. Methods: Electronic health records were reviewed for infants aged 6-36 months who were seen in the University of Illinois-Chicago Infant Oral Health Clinic. Caries experience was measured by tabulating the number of decayed (cavitated) or decalcified tooth surfaces recorded on the patients’ odontograms. Household smoking status was determined by guardian responses to tobacco use questions in the patients’ medical history. The association between household smoking and caries was tested by using stratified bivariate analysis to calculate age-adjusted odds ratio (OR) estimates and 95% confidence intervals (CI). Results: A total of 296 patients met study inclusion criteria. Of those, 180 (61%) had at least one decayed surface and 74 (25%) had at least one decalcified surface. Forty-six (16%) patients lived in a household with a current smoker. Living in a household with a current smoker was not significantly associated with having a decayed tooth surface (OR 1.25; 95% CI: 0.65, 2.43; P=.501) However, infants who lived in a household with a current smoker was were significantly more likely than those in smoke-free households to have at least one decalcified tooth surface (OR 2.50; 95% CI: 1.29, 4.86; P=.006) and had a higher mean number of decalcified surfaces (1.70 v. 0.74; P=.01). Conclusion: Exposure to secondhand smoke in the household may increase infants’ risk for dental decalcifications. Future research should control for other potential confounding factors.

description: We study the existence and stability criteria for circular geodesics of spherically symmetric tidal charged black hole~(BH). We investigate in details the equatorial causal geodesics of the tidal charged BH in comparison with spherically symmetric Reissner-Nordström BH spacetime. We particularly focused on both the null circular geodesics and time-like circular geodesics. Using the effective potential diagram, we have compared the geodesic structure between two spacetimes. We have derived the ISCO~(innermost stable circular orbit), MBCO~(marginally bound circular orbit) and CPO~(circular photon orbit) for both the space-times. Moreover, we have derived the \emph{quasi-normal modes~(QNM) frequency} in the \emph{eikonal limit} for both the spacetimes via Lyapunov exponent. In the Appendix section, we have shown that a spherically symmetric tidal-charged BH can act as particle accelerators with ultra-high center-of-mass~(CM) energy in the limiting case of \emph{maximal BH tidal charge~($q$)} and it is possible when two neutral particles are colliding near the horizon.

description: Choanal atresia causes serious posterior nasal obstruction. This defect is the leading cause of nasal surgery in newborns, although its etiology is largely unknown. Data from the National Birth Defects Prevention Study, a population-based case–control study, were used to examine associations between maternal self-reports of exposures and occurrence of choanal atresia in their offspring. Overall, 117 case and 8350 control mothers with deliveries from 1997 through 2007 provided telephone interview reports of pre-pregnancy (one year before conception) and periconceptional (one month before through three months after conception) exposures. The exposures analyzed were pre-pregnancy dietary intake, pre-pregnancy and periconceptional caffeine consumption, and periconceptional cigarette smoking, alcohol drinking, and medication use. Independent associations between each exposure and all choanal atresia cases combined (n = 117) and isolated choanal atresia cases (those without additional unrelated major defects; n = 61) were examined. Odds ratios (ORs), both unadjusted (uORs) and adjusted (aORs) for potential confounders, and 95% confidence intervals (CIs) were estimated using unconditional logistic regression analysis. For all choanal atresia cases combined, positive associations were observed with maternal pre-pregnancy intake in the highest quartile for vitamin B-12 (aOR = 1.9; CI = 1.1,3.1), zinc (aOR = 1.7; CI = 1.0,3.1), and niacin (aOR = 1.8; CI = 1.0,3.1), and intake in the lowest quartile for methionine (aOR = 1.6; CI = 1.0,2.6) and vitamin D (aOR = 1.6; CI = 1.0,2.4) compared to intake in the two intermediate quartiles combined. Further, a positive association was observed with periconceptional use of thyroid medications (uOR = 2.6; CI = 1.0,6.3) compared to no use of such medications. Among isolated choanal atresia cases, negative associations were observed for pantothenic acid (aOR = 0.4; CI = 0.2,0.9) and fat (aOR = 0.5; 95% CI = 0.2,1.0) intake in the lowest quartile compared to that in the intermediate quartiles, and positive associations were observed for periconceptional cigarette smoking (aOR = 2.3; CI = 1.1,4.7) compared to no smoking and pre-pregnancy daily coffee intake of 3 or more cups (aOR = 2.5; CI = 1.1,5.6) compared to intake of less than 1 cup per day. The positive association for periconceptional exposure to thyroid medications also persisted for isolated choanal atresia cases (uOR = 4.0; CI = 1.1,11.2). Because of the large number of associations tested, these findings may be due to chance. Alternatively, they may contribute new hypotheses regarding the etiology of choanal atresia; thus, requiring replication in additional studies.
