Libengaia

description: Libengaia (Libengaia) Linnavuori
 Remarks. This subgenus at present is confined to Central and West Africa. Linnavuori (1969) included five species including four new species from the Democratic Republic of the Congo. In this paper we describe five new species, three from Cameroon and two from Nigeria. The subgenus can be recognized by the following combination of characters: crown medially longer than next to eyes; subgenital plates with apical membranous (less sclerotized) thin appendage; style apophysis often with truncate apex and rounded or poorly developed preapical lobe; dorsal wall of aedeagal atrium less well developed and differentiated; aedeagus with shafts without apical thin process, preatrium not differentiated well from base of ventral process; ventral process forked near distal region.

description: Objective: Latino families raising children with mental
health needs report greater dissatisfaction with care compared with other
families. Activation is a promising strategy to eliminate disparities. This
study examined the comparative effectiveness of MePrEPA, an activation
intervention for Latino parents whose children receive mental health services.

Methods: A randomized controlled trial (N=172) was conducted
in a Spanish-language mental health clinic to assess the effectiveness of
MePrEPA, a four-week group psychoeducational intervention to enhance parent
activation among Latino parents. Inclusion criteria were raising a child who
receives services for mental health needs and ability to attend weekly
sessions. Outcomes were parent activation, education activation, quality of
school interaction, and parent mental health. Effectiveness of the intervention
was tested with a difference-in-difference approach for estimating linear mixed
models. Heterogeneity of treatment effect was examined.

Results: MePrEPA enhanced parent activation (ß=5.98,
95% confidence interval [CI]=1.42–10.53), education activation (ß=7.98,
CI=3.01–12.94), and quality of school interaction (ß=1.83, CI=.14–3.52) to a greater
degree than did a parent-support control group. The intervention’s impact on
parent activation and education outcomes was greater for participants whose children
were covered by Medicaid and were novices to therapy and those with low
activation at baseline. No statistically significant effects were observed in
parent mental health.

Conclusions: Activation among Latino parents was improved
with MePrEPA, which can be readily incorporated in current practices by mental
health clinics. Future work should replicate findings in a large number of
sites, adding behavioral measures and distal impacts while examining MePrEPA’s
effects across settings and populations.

We associate a microlocal Lefschetz class with a graph trace kernel and prove that this class is functorial with respect to the composition of kernels. We apply graph trace kernels to the microlocal Lefschetz fixed point formula for constructible sheaves.

description: Objective. Due to the radiosensitizing effect of biocompatible noble metal nanoparticles (NPs), their administration is considered to potentially increase tumor control in radiotherapy. The underlying physical, chemical and biological mechanisms of the NPs' radiosensitivity especially when interacting with proton radiation is not conclusive. In the following work, the energy deposition of protons in matter containing platinum nanoparticles (PtNPs) is experimentally investigated. Approach. Surfactant-free monomodal PtNPs with a mean diameter of (40 ± 10) nm and a concentration of 300 μg ml−1, demonstrably leading to a substantial production of reactive oxygen species (ROS), were homogeneously dispersed into cubic gelatin samples serving as tissue-like phantoms. Gelatin samples without PtNPs were used as control. The samples' dimensions and contrast of the PtNPs were verified in a clinical computed tomography scanner. Fields from a clinical proton machine were used for depth dose and stopping power measurements downstream of both samples types. These experiments were performed with a variety of detectors at a pencil beam scanning beam line as well as a passive beam line with proton energies from about 56–200 MeV. Main results. The samples' water equivalent ratios in terms of proton stopping as well as the mean proton energy deposition downstream of the samples with ROS-producing PtNPs compared to the samples without PtNPs showed no differences within the experimental uncertainties of about 2%. Significance. This study serves as experimental proof that the radiosensitizing effect of biocompatible PtNPs is not due to a macroscopically increased proton energy deposition, but is more likely caused by a catalytic effect of the PtNPs. Thus, these experiments provide a contribution to the highly discussed radiobiological question of the proton therapy efficiency with noble metal NPs and facilitate initial evidence that the dose calculation in treatment planning is straightforward and not affected by the presence of sensitizing PtNPs.

description: In 1959, Goodman [9] determined the minimum number of monochromatic triangles in a complete graph whose edge set is 2-coloured. Goodman (1985) [10] also raised the question of proving analogous results for complete graphs whose edge sets are coloured with more than two colours. In this paper, for n   sufficiently large, we determine the minimum number of monochromatic triangles in a 3-coloured copy of Kn. Moreover, we characterise those 3-coloured copies of Kn that contain the minimum number of monochromatic triangles.

Crown with median sulcus extending to half-length dark brown joining a transverse thin line of same color together forming a T with long arms; a speckled U-shaped spot touching transverse thin stripe on anterior half and one larger round spot on posterior half of crown, dark brown, posterior margin of crown dark brown. Face sparingly mottled with dark brown (Fig. 1G). Mesonotum with a median brown stripe, basal triangles brown, rest sparingly mottled with dark brown.
 Male genitalia. Pygofer 1.7× as long as wide at base in lateral view; dorsal margin straight, ventral margin convex, posterodorsal angle conically rounded; macrosetae scattered in posterior half. Style with short rounded preapical lobe, apophysis very short and thumb-like. Connective with stem as long as arms, apex not widened. Aedeagus with each shaft sinuate in lateral view, about as long as preatrium and about 0.25× as long as ventral process, in dorsal view each shaft laterally curved near apex; ventral process forked twice — first at midlength with paired processes directed dorsoanteriorly and second slightly beyond this fork resulting in laterally directed short branches close to apex, main stem of ventral process with two short, lateral, angular projections at the origin of the first pair of branches.
 Material examined. HOLOTYPE ♂, CAMEROON: Mkoemvon, vii–viii.1979, D. Jackson, B.M. 1980-74 (BMNH). Paratype ♂, same data as holotype (BMNH).

description: Abstract: "A simple algorithm for the computation of local minima of non-convex problems in one dimension is proposed. This algorithm avoids certain well known local minima which are distant from the global minimum, and can be used to improve the minima obtained using classical descent methods. The calculated minima have mesh scale oscillations typical of weakly converging sequences. It is shown that these local minima converge weakly to the correct limit for certain simple problems; however, numerical evidence suggests that the gradients may not converge to the correct weak limits, and this is verified using asymptotic expansions. Extensions to multiple dimensions and some numerical examples in two dimensions are considered."

Constraining Nuclear Structure Physics of Coherent Elastic Neutrino-Nucleus Scattering
Creators: name: Dessel, Nils Van
name: Jachowicz, Natalie
name: Vishvas Pandey
Publisher: name: Zenodo
Year: 2020

description: Recent measurement of coherent elastic neutrino-nucleus scattering (CEvNS) process by COHERENT collaboration has opened a new portal of exploring various BSM processes. The major uncertainty in CEvNS stems from nuclear constraints on form-factors, and hence any experimentally measured deviation from the SM number of events can either be attributed to a lack of knowledge of the nucleon distributions in target nuclei or to new physics. Here, we present charge and weak nuclear form-factors and CEvNS cross section calculations on various nuclei using a microscopic many-body nuclear theory model based on Hartree-Fock approach with a Skyrme nuclear potential. We validate argon charge form factor predictions against the data from elastic electron scattering and compare argon weak form factor calculations with other theoretical approaches in order to estimate a theoretical uncertainty that could help extracting new physics signals in liquid-argon based CEvNS experiments.

description: We investigate the Affleck-Dine baryogenesis after D-term inflation with a positive Hubble-induced mass term for a B-L flat direction. It stays at a large field value during D-term inflation, and just after inflation ends it starts to oscillate around the origin of the potential due to the positive Hubble-induced mass term. The phase direction is kicked by higher-dimensional Kahler potentials to generate the B-L asymmetry. The scenario predicts nonzero baryonic isocurvature perturbations, which would be detected by future observations of CMB fluctuations. We also provide a D-term inflation model which naturally explain the coincidence of the energy density of baryon and dark matter.

description: The RENO experiment has been taking data since August 2011 and successfully measured the smallest neutrino mixing angle, theta13, with neutron captured on Gadolinium (n-Gd) in target detector region. The experiment has also measured the mixing angle using an independent sample of neutron captures on Hydrogen (n-H). Because of a large accidental background in the n-H sample, an improved technique has been developed to make an effective removal of the background. The n-H analysis utilizes events in both target and gamma-catcher and thus obtains a more than twice larger sample than that of n-Gd. This independent measurement provides an important cross-check on the systematic uncertainties of the theta13 measurement from the n-Gd sample. In this presentation, we will also present a combined result based on the n-H rate-only and n-Gd rate-and-spectrum measurements.

description: Recent years have witnessed intense development of randomized methods for low-rank approximation. These methods target principal component analysis (PCA) and the calculation of truncated singular value decompositions (SVD). The present paper presents an essentially black-box, fool-proof implementation for Mathworks' MATLAB, a popular software platform for numerical computation. As illustrated via several tests, the randomized algorithms for low-rank approximation outperform or at least match the classical techniques (such as Lanczos iterations) in basically all respects: accuracy, computational efficiency (both speed and memory usage), ease-of-use, parallelizability, and reliability. However, the classical procedures remain the methods of choice for estimating spectral norms, and are far superior for calculating the least singular values and corresponding singular vectors (or singular subspaces).

Model-independent way to test the CPT violation using NOvA, T2K and INO experiments
Creators: name: Kaur, Daljeet
Publisher: name: Zenodo
Year: 2020

description: Charge-Parity-Time (CPT) symmetry governs that the oscillation parameters for neutrinos and anti-neutrinos are to be identical. Different mass and mixing parameters for these particles may give us a possible hint for CPT violation in the neutrino sector. Using this approach, we discuss the ability of long-baseline and atmospheric neutrino experiments to determine the difference between mass squared splittings ($\Delta m^{2}_{32}-\Delta\bar{m}^{2}_{32}$) and atmospheric mixing angles ($\sin^{2}\theta_{23}-\sin^{2}\bar{\theta}_{23}$) of neutrinos and anti-neutrinos. We show the joint sensitivity of the T2K, NOvA and INO experiments to such CPT violating observables in different possible combinations of octant for neutrinos and anti-neutrinos.

description: This monography presents results related to the convex geometry of a family of simplicial complexes called ``subword complexes''. These simplicial complexes are defined using the Bruhat order of Coxeter groups. Despite a simple combinatorial definition much of their combinatorial properties are still not understood. In contrast, many of their known connections make use of specific geometric realizations of these simplicial complexes. When such realizations are missing, many connections can only be conjectured to exist. This monography lays down a framework using an alliance of algebraic combinatorics and discrete geometry to study further subword complexes. It provides an abstract, though transparent, perspective on subword complexes based on linear algebra and combinatorics on words. The main contribution is the presentation of a universal partial oriented matroid whose realizability over the real numbers implies the realizability of subword complexes as oriented matroids.

Diese Simplizialkomplexe werden mit Hilfe der Bruhat-Ordnung von Coxeter-Gruppen definiert. Trotz einer einfachen kombinatorischen Definition werden viele ihrer kombinatorischen Eigenschaften immer noch nicht verstanden. Spezifische geometrische Realisierungen dieser Simplizialkomplexe machen neue Herangehensweisen an Vermutungen des Gebiets m\"oglich. Wenn solche Verbindungen fehlen, können viele Zusammenhänge nur vermutet werden. Diese Monographie legt einen Rahmen fest, in dem eine Allianz aus algebraischer Kombinatorik und diskreter Geometrie verwendet wird, um weitere Subwortkomplexe zu untersuchen. Es bietet eine abstrakte und transparente Perspektive auf Teilwortkomplexe, die auf linearer Algebra und Kombinatorik von Wörtern basiert. Der Hauptbeitrag ist die Darstellung eines universellen, nur teilweise orientierten Matroids, dessen Realisierbarkeit über den reellen Zahlen die Realisierbarkeit von Teilwortkomplexen als orientierte Matroide impliziert.

description: This paper shows that in this luminous universe, the speed of light is instantaneous across it according to Hubble's law, c=HR (where c is the speed of light, H is Hubble's constant and R is the length of the luminous universe). Therefore, instantaneous propagation or quantum entanglement or spooky action is not superluminal as deridingly predicted but luminal. The various Bell tests actually attest to this instantaneous luminal speed. Thus, the Bell tests did not violate the postulate of relativity.

(see below) have the style with a well-developed angular preapical lobe whereas the remaining species have the preapical lobe poorly developed, which Linnavuori (1969) called rounded. Among the latter group of species, L. (L.) vermiculata , L. (L.) narcissa , L. (L.) helias , L. (L.) nicias , and L. (L.) milionia have a fairly long apophysis of the style but not as long as in the new species.

description: The current status of determinations of the QCD running quark masses is reviewed. Emphasis is on recent progress on analytical precision determinations based on finite energy QCD sum rules. A critical discussion of the merits of this approach over other alternative QCD sum rules is provided. Systematic uncertainties from both the hadronic and the QCD sector have been recently identified and dealt with successfully, thus leading to values of the quark masses with unprecedented accuracy. Results currently rival in precision with lattice QCD determinations.

description: In the recent past, the interest in microbiome research has increased because studies have suggested a strong link of microbial communities to their hosts. Along with a beneficial role of microbes, bacteria and viruses can have harmful effects and this pathogenic potential is of utmost interest. For public health, a robust and fast detection of pathogens is critical because it reduces the time for diagnosis and treatment and can lower the risk of transmission and mortality. This requires diagnostic assays to cover a broad spectrum for various potentially disease-causing agents. In the past, genome sequencing technologies have demonstrated both the immense variety of pathogens and the complexity of microbial communities. Reaching beyond the genetic potential that is addressed by metagenomics, metaproteomics enables investigating the metabolic and cellular pathways in which microbial enzymes are key players. Proteomics has reached a mature stage where it cannot only be used in a research context, but also for diagnostics as it had been demonstrated with newly emerging SARS-CoV-2 applications. This thesis aims at investigating the potential of using meta-omics technology and corresponding bioinformatics methods to process, analyze, and interpret data from experimental pathogen and microbiome samples. This work focuses on developing computational methods for detecting and characterizing bacterial and viral pathogens as well as for integrating host and microbiome data at different meta-omics levels. In addition, both experimental and bioinformatics benchmarking studies are performed. Finally, the aim is also to integrate methods and data for multiple omics levels, including metagenomics, metatranscriptomics, and metaproteomics.

description: This short communication paper reports the effects of manufacturing parameters (raster angle, layer height, and print orientation) on the flexural properties of material extrusion (ME) Ultrafuse Steel 316L. Flexural specimens were produced with four raster angles: ±30°, ±45°, ±75°, and 0°/90°, with each raster angle printed at three layer heights: 0.1, 0.15, and 0.2 mm. The former combinations were of ‘flat’ print orientation, and a limited amount of ‘on-edge’ print orientation specimens were included for a general comparison. Statistical analysis was performed on the flexural strength data. Furthermore, the digital image correlation (DIC) technique was employed to study the deformation modes/mechanisms of the specimens. Comparable flexural strength results were obtained for the two print orientations. However, the ‘on edge’ print orientation specimens outperformed their counterparts. The ±30° raster angled specimens outperformed all other specimens in both the print orientations, recording the highest flexural strengths. Uniform deformation modes of the specimens were evidenced from the DIC analysis, where the effects of internal voids/porosity on subsequent mechanical properties were found to be minor. Overall, the results presented herein will increase confidence in employing the ME process for Steel 316L for applications involving bending loads.
New Inclusive Cross Section Measurements from MINERvA
Creators: name: Filkins, Amy
Publisher: name: Zenodo
Year: 2020

description: In an era of precision neutrino oscillation experiments using improved technology that generate large statistical samples, it is important to understand the properties of neutrino interactions on nuclei over a large volume of kinematic phase space. The MINERvA experiment, which utilizes the NuMI neutrino beam at Fermilab, measures cross sections across multiple materials ranging from helium to lead, and is able to compare results to imperfect models of these neutrino interactions. I will show a double differential cross section measurement, in variables of the longitudinal and transverse momenta of the muon, of charged current muon-neutrino interactions in hydrocarbon at a neutrino energy of <3.5 GeV> with 3.34E20 protons on target. This result is advantageous for comparisons with theorists since it is done in well-defined easily measurable variables, and is able to highlight areas in which there are model deficiencies.
Optimizing optical Bragg scattering for single-photon frequency conversion

description: We develop a systematic theory for optimising single-photon frequency conversion using optical Bragg scattering. The efficiency and phase-matching conditions for the desired Bragg scattering conversion as well as spurious scattering and modulation instability are identified. We find that third-order dispersion can suppress unwanted processes, while dispersion above the fourth order limits the maximum conversion efficiency. We apply the optimisation conditions to frequency conversion in highly nonlinear fiber, silicon nitride waveguides and silicon nanowires. Efficient conversion is confirmed using full numerical simulations. These design rules will assist the development of efficient quantum frequency conversion between multicolour single photon sources for integration in complex quantum networks.

description: The relevance of cellular in vitro models highly depends on their ability to mimic the physiological environment of the respective tissue or cell niche. Static culture conditions are often unsuitable, especially for endothelial models, since they completely neglect the physiological surface shear stress and corresponding reactions of endothelial cells (ECs) such as alignment in the direction of flow. Furthermore, formation and maturation of the glycocalyx, the essential polysaccharide layer covering all endothelial surfaces and regulating diverse processes, is highly dependent on applied fluid flow. This fragile but utterly important macromolecular layer is hard to analyze, its importance is often underestimated and accordingly neglected in many endothelial models. Therefore, we exposed human umbilical vein ECs (HUVECs) and human induced pluripotent stem cell-derived ECs (iPSC-ECs) as two relevant EC models in a side-by-side comparison to static and physiological dynamic (6.6 dyn cm−2) culture conditions. Both cell types demonstrated an elongation and alignment along the flow direction, some distinct changes in glycocalyx composition on the surface regarding the main glycosaminoglycan components heparan sulfate, chondroitin sulfate or hyaluronic acid as well as an increased and thereby improved glycocalyx thickness and functionality when cultured under homogeneous fluid flow. Thus, we were able to demonstrate the maturity of the employed iPSC-EC model regarding its ability to sense fluid flow along with the general importance of physiological shear stress for glycocalyx formation. Additionally, we investigated EC monolayer integrity with and without application of surface shear stress, revealing a comparable existence of tight junctions for all conditions and a reorganization of the cytoskeleton upon dynamic culture leading to an increased formation of focal adhesions. We then fabricated cell sheets of EC monolayers after static and dynamic culture via non-enzymatic detachment using thermoresponsive polymer coatings as culture substrates. In a first proof-of-concept we were able to transfer an aligned iPSC-EC sheet to a 3D-printed scaffold thereby making a step in the direction of vascular modelling. We envision these results to be a valuable contribution to improvements of in vitro endothelial models and vascular engineering in the future.

Libengaia

description: Libengaia (Nandiana) subgen. nov.
 Type species: Litura bharatiensis Malhotra & Sharma, here designated.
 Diagnosis. Crown as along medially as next to eyes, subgenital plate without apical membranous appendage, each aedeagal shaft with apical process or processes, a constriction precedes origin of ventral process and ventral process forked close to base.
 Description. The new subgenus differs from the nominotypical subgenus by the following characters: a) Crown as long medially as next to eyes (crown longer medially than next to eyes in nominotypical subgenus); b) subgenital plate without distal membranous appendage (present in typical subgenus); c) aedeagal shaft longer than ventral processes rarely shorter, each shaft with apical process or processes (aedeagal shaft short, shorter than ventral process, each shaft without apical processes in nominotypical subgenus); d) preatrial processes are paired and of unequal length (atrial process in the nominotypical subgenus single and distally bifurcate); e) junction between preatrium and ventral process constricted (not constricted in the nominotypical subgenus), and f) ventral process of the aedeagus forked at base so much so they appear pair of processes (in the typical subgenus the ventral process of the aedeagus is single and forked near apex).
 Etymology. The name of the subgenus is derived from the Sanskrit word “ nandi ” meaning joy, satisfaction, to which the suffix “iana” is added; gender feminine.

Hints and Tests of Dark Neutrino Sectors
Creators: name: Matheus Hostert
Publisher: name: Zenodo
Year: 2020

description: Experimental searches for light dark sectors can help shine light on the origin of neutrino masses. In this poster I present one possibility of a dark sector that realizes the inverse seesaw at the MeV scale, and offers new experimental signatures to be searched for. The model, in fact, can accommodate several experimental anomalies, such as the MiniBooNE low energy excess. We are interested in enriching a heavy neutrino sector with a dark $U(1)^\prime$ symmetry, whose mediator kinetically mixes with hypercharge. This scenario produces new production and decay channels for heavy neutral leptons.
