description: Using case studies from Aşıklı Höyük, Çatalhöyük, Boncuklu Tarla, Göbekli Tepe (all Turkey), and Monjukli Depe (southern Turkmenistan), this study presents a framework for in-depth research on prehistoric earthen architecture in southwestern and central Asia. It demonstrates the challenges and potential for innovative and comparative studies based on interdisciplinary approaches and the use of architectural, microstratigraphic, and microarchaeological analyses. Furthermore, it sheds new light on issues related to various aspects of building continuity which is commonly recognised as a very important phenomenon in the Neolithic but could have different facets. The study attempts to discuss the reasons behind the local decisions to use and recycle specified building materials. In addition, it evaluates – in relation to particular sites – the usefulness of specific analyses for reconstruction of daily, seasonal, or annual practices. Advanced analyses of floors and fire installations, for instance, can contribute not only to the identification of indoor and outdoor surfaces but also to a better understanding of activity areas and the intensity of use within particular spaces. Variations and different combinations of mudbrick, mortar, and plaster recipes allow for insights into how earth and sediment material were used to mark collective and individual identity through the performance of a building. Recognising reused materials and features allows us to trace further the nature of prehistoric societies and local architectural dialects.

Context aware high dynamics gnss-ins for interference mitigation

Publisher: name: University of Calgary

description: Bibliography: p. 193-199
description: Autonomous navigation systems used in missiles are mostly dependent on Global Positioning System (GPS) as a primary means of navigation. GPS usage has limitations in terms of missile high dynamics and expected signal interference in the battlefield. Due to the conflicting bandwidth requirements in Phase/ Frequency Lock Loops (PLLs/ FLLs), a novel FLL-assisted-PLL is proposed for very high dynamic conditions with reduced measurement noise and capabilities to cope with interference. The design is based on fuzzy systems and is used to generate the required Numerical Control Oscillator (NCO) tuning frequency with the information provided by phase and frequency discriminators. Detailed system design and performance analysis are presented where scenarios include high dynamics and different types and levels of interference are introduced. The designed system is compared also against 3rd order PLLs, with narrow and wide bandwidths, standard FLL-assisted-PLL, in addition to a Kalman Filter (KF) based PLL. Moreover, to insure robustness of the new system during periods of GPS blockage due to very high interference levels, the system is integrated with additional aiding that can provide external Doppler measurements. Two approaches are introduced to accomplish this. The first approach is to use the measurements available from the missile Inertial Measurement Unit (IMU) as these are not affected by interference. The second approach is to get the benefit from the modem GPS signals such as L2C signal which can be assumed not to be affected by interference if a narrow band interference signal is aimed at the primary GPS signal L 1. Performance assessments results demonstrate the enhanced performance of the proposed system where better tracking continuity during high dynamics up to 20 g's of acceleration and more accurate measurements in interference free environments and in low and medium interference levels up to jamming-to-signal ratios of 40 dB are achieved for the stand alone system, and at very high interference levels for the aided system.

Wolf et al. misapply both Schiff's conjecture and the results of their own analysis when they conclude that atom interferometers are tests of the weak equivalence principle which only become redshift tests if Schiff's conjecture is invalid. Atom interferometers are direct redshift tests in any formalism.

description: Background: Youths with eating disorders (EDs) engaging in nonsuicidal self-injury (NSSI) are at higher suicide risk because EDs and NSSI are associated with suicidality. However, epidemiologic data on NSSI lacks in the vulnerable group of youth ED inpatients. Methods: This retrospective chart review included patients up to 18 years of age with an ICD-10 diagnosis of anorexia nervosa, restricting type (AN-R), anorexia nervosa, binge-purge type (AN-BP), and bulimia nervosa (BN), treated at the child and adolescent inpatient department of the University Hospital in Berlin, Germany, between 1990 and 2015. Across and within ED subgroups, lifetime NSSI prevalence, methods of self-harm, and clinical correlates were evaluated. Independent correlations of demographic and clinical factors with NSSI were identified via multivariable regression models. Results: Of 382 inpatients (median = 15.6 (range = 9-18) years, females = 97.1%), 21.5% reported lifetime NSSI, consisting of cutting = 86.6%, scratching = 12.2%, and hitting = 8.5%. NSSI was more frequent in BN (47.6%) and AN-BP (39.3%) than AN-R (8.3%) (phi = 0.43). Across ED subgroups, NSSI was associated with a higher prevalence of psychiatric comorbidities (AN-R: phi = 0.55; AN-BP: phi = 0.69; BN: phi = 0.78), suicidal ideation (AN-R: phi = 0.30; AN-BP: phi = 0.38; BN: phi = 0.29), and psychiatric medication use (AN-R: phi = 0.23; AN-BP: phi = 0.64; BN: phi = 0.60). In multivariable regression analyses, NSSI was independently associated with a higher prevalence of psychiatric comorbidities (AN-R: OR = 2.93 [1.42, 6.04]; AN-BP: OR = 2.67 [1.13, 6.31]; BN: OR = 3.75 [1.71, 8.23]). Additionally, independent correlates with NSSI in AN-R included a higher prevalence of suicidal ideation (OR = 0.21 [0.72, 0.64]) and less weekly weight gain (OR = 0.03 [0.02, 0.43]), while in BN, NSSI was correlated with longer inpatient treatment duration (OR = 1.01 [1.00, 1.02]). Conclusions: There is a high lifetime prevalence of NSSI among youth with AN and BN requiring inpatient treatment, especially those with binge-purge behaviors. Treatment programs must be tailored to address psychiatric comorbidities and suicidality to improve patient care and suicide prevention. Trial registration: This study was not considered a clinical trial but a retrospective chart review based on routinely assessed clinical parameters. The study includes data from human participants, however: (1) no intervention and no prospective assignment to interventions were performed, and (2) no evaluation of an intervention on participants was accomplished.

As a consequence of this result, we then investigate the relation between analytic functions and $L^p$-convergent series of Hermite polynomials. Finally, our results are applied to Widder's representation for a class of Brownian martingales, retrieving a characterization for the moments of Widder's measure.

description: This essay provides a road map for theatre historians, archivists, and librarians interested in understanding theatrical scrapbooks as a genre. It argues for the importance of the ordinary theatrical scrapbook as both archive and medium. As an archive, the theatrical scrapbook is a repository for performance ephemera. As a medium, scrapbooks record how past theatre aficionados merged the stage and the page, image and print, live performances and representations of them. Taking the scrapbook holdings of Ohio State’s Theatre Research Institute, the essay offers a brief history of theatrical scrapbooks; a taxonomy to help scholars navigate and interpret albums; and a sampling of the historical and theoretical questions that scrapbooks inspire and help answer.
Biosynthesis of cuticular alkylresorcinols in selected grass species Brachypodium distachyon and Secale cereale
Creators: name: Yao, Ruonan
Publisher: name: University of British Columbia
Year: 2011

description: Alkylresorcinols are phenolic lipids which occur in diverse plant species as well as microorganisms. In plants, alkylresorcinols are usually deposited at or near the surfaces where they are thought to serve as a first line of defense. Earlier work in our lab had shown the surface accumulation of alkylresorcinols in Secale cereale leaves was mainly restricted to the cuticle. However, direct evidence showing the protective role of these bioactive compounds at the surface is still insufficient. The current work was to investigate the biosynthesis of cuticular alkylresorcinols in order to get a better understanding of their biological function. This research focused on S. cereale, since it had previously been shown to contain relatively large amounts of alkylresorcinols, and on Brachypodium distachyon, a closely related genetic model system with completely sequenced genome. First, chemical analyses revealed that the cuticular wax covering leaves of B. distachyon included 5% of alkylresorcinols with alkyl chains varying from C₁₇ to C₂₅. Therefore, it was hypothesized that both species have genes encoding alkylresorcinol synthases (ARSs). A central goal of this work was to clone and characterize potential ARSs. One ARS (BdARS) was cloned from B. distachyon by mining the Brachypodium expressed sequence tag libraries and one ARS (ScARS) was cloned from S. cereale using a homology-based cloning strategy. In vivo biochemical characterization in yeast Saccharomyces cerevisiae demonstrated that both enzymes were capable of using C₁₀ to C₂₂ fatty acyl-CoAs with malonyl-CoA to generate a broad range of alkylresorcinols. Organ-specific expression in leaves but not in roots was observed for both BdARS and ScARS. Additionally, the expression pattern of ScARS matched the time-course of cuticular alkylresorcinol accumulation along the leaf of S. cereale. An investigation into their subcellular localization revealed that both ARSs were likely localized to the endoplasmic reticulum membrane. All these results taken together support the idea that BdARS and ScARS are the enzymes responsible for the biosynthesis of cuticular alkylresorcinols, and that the cuticular alkylresorcinols are indeed biosynthesized for a protective function associated with the wax lining the surface of grass leaves.

description: Comprehenders are known to generate expectations about upcoming linguistic input at the sentence and discourse level. However, most previous studies on prediction focused mainly on word-induced brain activity rather than examining neural activity preceding a critical stimulus in discourse processing, where prediction actually takes place. In this EEG study, participants were presented with multiple sentences resembling a discourse including conditional sentences with either only if or if, which are characterized by different semantics, triggering stronger or weaker predictions about the possible continuation of the presented discourses, respectively. Results revealed that discourses including only if, as compared to discourses with bare if, triggered an increased predictive neural activity before the expected critical word, resembling the readiness potential. Moreover, word-induced P300 brain responses were found to be enhanced by unpredictable discourse continuations and reduced in predictable discourse continuations. Intriguingly, brain responses preceding and following the critical word were found to be correlated, which yields evidence for predictive activity modulating word-induced processing on the discourse level. These findings shed light on the predictive nature of neural processes at the discourse level, critically advancing our understanding of the functional interconnection between discourse understanding and prediction processes in brain and mind.

description: The furin cleavage site (FCS) in SARS-CoV-2 is unique within the Severe acute respiratory syndrome-related coronavirus (SrC) species. We re-assessed diverse SrC from European horseshoe bats and analyzed the spike-encoding genomic region harboring the FCS in SARS-CoV-2. We reveal molecular features in SrC such as purine richness and RNA secondary structures that resemble those required for FCS acquisition in avian influenza viruses. We discuss the potential acquisition of FCS through molecular mechanisms such as nucleotide substitution, insertion, or recombination, and show that a single nucleotide exchange in two European bat-associated SrC may suffice to enable furin cleavage. Furthermore, we show that FCS occurrence is variable in bat- and rodent-borne counterparts of human coronaviruses. Our results suggest that furin cleavage sites can be acquired in SrC via conserved molecular mechanisms known in other reservoir-bound RNA viruses and thus support a natural origin of SARS-CoV-2.

description: Background: Sarcomas are a heterogeneous group of rare malignant tumors with more than 100 subtypes. Accurate diagnosis remains challenging due to a lack of characteristic molecular or histomorphological hallmarks. A DNA methylation-based tumor profiling classifier for sarcomas (known as sarcoma classifier) from the German Cancer Research Center (Deutsches Krebsforschungszentrum) is now employed in selected cases to guide tumor classification and treatment decisions at our institution. Data on the usage of the classifier in daily clinical routine are lacking. Methods: In this single-center experience, we describe the clinical course of five sarcoma cases undergoing thorough pathological and reference pathological examination as well as DNA methylation-based profiling and their impact on subsequent treatment decisions. We collected data on the clinical course, DNA methylation analysis, histopathology, radiological imaging, and next-generation sequencing. Results: Five clinical cases involving DNA methylation-based profiling in 2021 at our institution were included. All patients' DNA methylation profiles were successfully matched to a methylation profile cluster of the sarcoma classifier's dataset. In three patients, the classifier reassured diagnosis or aided in finding the correct diagnosis in light of contradictory data and differential diagnoses. In two patients with intracranial tumors, the classifier changed the diagnosis to a novel diagnostic tumor group. Conclusions: The sarcoma classifier is a valuable diagnostic tool that should be used after comprehensive clinical and histopathological evaluation. It may help to reassure the histopathological diagnosis or indicate the need for thorough reassessment in cases where it contradicts previous findings. However, certain limitations (non-classifiable cases, misclassifications, unclear degree of sample purity for analysis and others) currently preclude wide clinical application. The current sarcoma classifier is therefore not yet ready for a broad clinical routine. With further refinements, this promising tool may be implemented in daily clinical practice in selected cases.

description: We analyze the effects of the s-channel Higgs bosons exchange on the charginos and neutralinos-pair production in proton-proton collision at the CERN Large Hadron Collider (LHC) in the following channels: $pp \to \Cha^+\Cha^-/\Neu^0\Neu^0 + X$, within the minimal supersymmetric standard model (MSSM). Assuming the usual GUT relation between $M_1$ and $M_2$ at the weak scale, we found that substantial enhancement can be obtained through s-channel Higgs bosons exchange in the mixed regime where $M_2 \sim |μ|$ with moderate to large $\tanβ$ at the resonance of the heavy Higgs bosons. By Combining the phenomenological constraints on neutralinos and charginos, we may still find regions of parameter space where charginos and neutralinos-pair production at the LHC from $b\bar b$ initial state can be large and observable at LHC. We also compute the full complete set of electroweak (EW) contributions to $pp\to gg\to \Cha^+\Cha^-/\Neu^0\Neu^0 + X$ at one loop level in the general MSSM. The analytical computation of the complete tree level amplitude for $b\bar{b} \to \Cha^+\Cha^-/\Neu^0\Neu^0 + X$, including s-channel Higgs exchange, is given.

Jadeitite formed during subduction: In situ zircon geochronology constraints from two different tectonic events within the Guatemala Suture Zone

description: Jadeitite is a rare rock type associated with high-pressure–low-temperature blocks within serpentinite matrix mélanges. Models of formation involve precipitation from subduction-zone aqueous fluids veining the overlying mantle wedge (P-type), or metasomatism of igneous and/or sedimentary protoliths previously emplaced into the mélange (R-type). Age determinations of mélange lithologies provide constraints on the timing of “peak metamorphism” and subsequent exhumation. The timing of jadeitite formation, particularly in the rich source of the Guatemala Suture Zone (GSZ), is a controversial subject needing further attention.
Over 80 in situ zircon crystals from three jadeitites and two mica–albite rocks from the North Motagua Mélange and one phengite jadeitite from the South Motagua Mélange of the GSZ were studied for age and trace-element determination. Most of these zircons are characterized by low Th/U ratios, depleted chondrite-normalized REE patterns relative to zircons from oceanic gabbros, and contain fluid and mineral inclusions that reflect the primary mineralogy (i.e., jadeite) and context (i.e., crystallization from an aqueous fluid) of the host rock, and thus formed during jadeitite crystallization. The SHRIMP-RG and LAM-ICP-MS U–Pb dates from zircon indicate that jadeitites and mica–albite rocks from the GSZ were formed through vein precipitation at ~98−80 and ~154–158 Ma, respectively. These data show (a) older ages that indicate jadeitite crystallization occurred ~10–30 Ma before the preserved subduction-zone peak metamorphism (e.g., exhumed eclogite), and (b) a second group of ages slightly younger than, or similar to, exhumation ages given by Ar–Ar dates from micas. Similar relationships occur at other jadeitite occurrences, such as the Syum-Keu ultramafic complex in the Polar Urals (Russia) and the serpentinite mélanges of the Río San Juan complex (Dominican Republic). The data argue for formation of jadeitite within the mantle wedge during active subduction. Thus, jadeitite provides a record of fluid introduction into the mantle wedge during subduction rather than during exhumation.

description: Tumors and their location distinctly alter both local and global brain connectivity within the ipsilesional hemisphere of glioma patients. Gliomas that infiltrate networks and systems, such as the motor system, often lead to substantial functional impairment in multiple systems. Network-based statistics (NBS) allow to assess local network differences and graph theoretical analyses enable investigation of global and local network properties. Here, we used network measures to characterize glioma-related decreases in structural connectivity by comparing the ipsi- with the contralesional hemispheres of patients and correlated findings with neurological assessment. We found that lesion location resulted in differential impairment of both short and long connectivity patterns. Network analysis showed reduced global and local efficiency in the ipsilesional hemisphere compared to the contralesional hemispheric networks, which reflect the impairment of information transfer across different regions of a network.

description: [Abridged] We present a new grid of massive population III star models including the effects of rotation on the stellar structure and chemical mixing, and magnetic torques for the transport of angular momentum. Based on the grid, we also present a phase diagram for the expected final fates of rotating massive Pop III stars. Our non-rotating models become redder than the previous models in the literature, given the larger overshooting parameter adopted in this study. In particular, convective dredge-up of the helium core material into the hydrogen envelope is observed in our non-rotating very massive star models (>~200 Msun), which is potentially important for the chemical yields. On the other hand, the stars become bluer and more luminous with a higher rotational velocity. With the Spruit-Tayler dynamo, our models with a sufficiently high initial rotational velocity can reach the critical rotation earlier and lose more mass as a result, compared to the previous models without magnetic fields. The most dramatic effect of rotation is found with the so-called chemically homogeneous evolution (CHE), which is observed for a limited mass and rotational velocity range. CHE has several important consequences: 1) Both primary nitrogen and ionizing photons are abundantly produced. 2) Conditions for gamma-ray burst progenitors are fulfilled for an initial mass range of 13 - 84 Msun. 3) Pair instability supernovae of type Ibc are expected for 84 -190 Msun and 4) Both a pulsational pair instability supernova and a GRB may occur from the same progenitor of about 56 - 84 Msun, which might significantly influence the consequent GRB afterglow. We find that CHE does not occur for very massive stars (> 190 Msun), in which case the hydrogen envelope expands to the red-supergiant phase and the final angular momentum is too low to make any explosive event powered by rotation.

description: During the past 40,000 years, global climate has moved into and out of a full glacial period, with the deglaciation marked by several millennial-scale rapid climate change events. Here we investigate the ecological response of deep-sea coral communities to both glaciation and these rapid climate change events. We find that the deep-sea coral populations of Desmophyllum dianthus in both the North Atlantic and the Tasmanian seamounts expand at times of rapid climate change. However, during the more stable Last Glacial Maximum, the coral population globally retreats to a more restricted depth range. Holocene populations show regional patterns that provide some insight into what causes these dramatic changes in population structure. The most important factors are likely responses to climatically driven changes in productivity, [O2] and [CO32–].

description: This paper intends to evaluate the capacity of self-purification of a river, on the influence of a dynamic wave. Therefore, it was developed a mathematical modeling, where it were used Hydrodynamic Equations, combined with the Advective – Diffusive Equation, to describe the behavior of the transport processes in urban rivers. The results showed that the hydraulic parameters play an important game in the behavior of the concentration of the bodies of water.

description: Temperatures in the tropical tropopause layer (TTL) play an important role in stratosphere–troposphere exchange and in the formation and maintenance of thin cirrus clouds. Many previous studies have examined the contributions of extratropical and equatorial waves to the TTL using coarse-vertical-resolution satellite and reanalysis data. In this study, the authors provide new insight into the role of extratropical and equatorial waves in the TTL using high-vertical-resolution GPS radio occultation data.
The results examine the influence of four different wave forcings on the TTL: extratropical waves that propagate vertically into the stratosphere, extratropical waves that propagate meridionally into the subtropical stratosphere, extratropical waves that propagate meridionally into the subtropical troposphere, and the equatorial planetary waves. The vertically and meridionally propagating extratropical stratospheric waves are associated with deep, zonally symmetric temperature anomalies that extend and amplify with height throughout the lower-to-middle tropical stratosphere. In contrast, the extratropical tropospheric waves and the equatorial planetary waves are associated with tropical temperature anomalies that are confined below 20-km altitude. The equatorial planetary waves dominate the zonally asymmetric component of the TTL temperature field, and both the equatorial planetary waves and the extratropical tropospheric waves are linked to large temperature variability in a 1–2-km-deep layer near the tropical tropopause. The fine vertical scale of the TTL temperature features associated with the equatorial planetary waves and the extratropical tropospheric waves is only readily apparent in high-vertical-resolution data.

description: Mechanisms of epithelial renewal in the alveolar compartment remain incompletely understood. To this end, we aimed to characterize alveolar progenitors. Single-cell RNA-sequencing (scRNA-seq) analysis of the HTII-280+/EpCAM+ population from adult human lung revealed subclusters enriched for adult stem cell signature (ASCS) genes. We found that alveolar progenitors in organoid culture in vitro show phenotypic lineage plasticity as they can yield alveolar or bronchial cell-type progeny. The direction of the differentiation is dependent on the presence of the GSK-3β inhibitor, CHIR99021. By RNA-seq profiling of GSK-3β knockdown organoids we identified additional candidate target genes of the inhibitor, among others FOXM1 and EGF. This gives evidence of Wnt pathway independent regulatory mechanisms of alveolar specification. Following influenza A virus (IAV) infection organoids showed a similar response as lung tissue explants which confirms their suitability for studies of sequelae of pathogen-host interaction.

description: Polar oxides are of much interest in materials science and engineering. Their symmetry-dependent properties such as ferroelectricity/multiferroics, piezoelectricity, pyroelectricity, and second-order harmonic generation (SHG) effect are important for technological applications. However, polar crystal design and synthesis is challenging, because multiple effects, such as steric or dipole-dipole interactions, typically combine to form non-polar structures; so the number of known polar materials, especially polar magnetoelectric materials, is still severely restricted. Therefore, it is necessary for the material science community to develop new strategies to create these materials.
