description: Abstract Evaporation—a key process for water exchange between soil and atmosphere—is controlled by internal water fluxes and surface vapor fluxes. Recent studies demonstrated that the dynamics of the water flow in corners determine the time behavior of the evaporation rate. The internal water flux of the porous media is often described by capillary flow assuming complete wetting. Particularly, the crucial influence of partial wetting, that is, the nonlinear contact angle dependency of the capillary flow has been neglected so far. The focus of the paper is to demonstrate that SiO2-surfaces can exhibit contact angles of about 40°. This reduces the internal capillary flow by 1 order of magnitude compared to complete wetting. First, we derived the contact angle by inverse modeling. We conducted a series of evaporation experiments in a 2-D square lattice microstructure connected by lognormal distributed throats. We used an explicit analytical power series solution of the single square capillary model. A contact angle of 38° ± 1° was derived. Second, we directly measured the contact angle of the Si-SiO2 wafer using the Drop Shape Analyzer Krüss 100 and obtained an averaged contact angle of 42° ± 2°. The results support the single square capillary model as an appropriate model for the description of the evaporation process in an ideal square capillary.

description: In this paper, we deal with low-complexity near-optimal detection/equalization in large-dimension multiple-input multiple-output inter-symbol interference (MIMO-ISI) channels using message passing on graphical models. A key contribution in the paper is the demonstration that near-optimal performance in MIMO-ISI channels with large dimensions can be achieved at low complexities through simple yet effective simplifications/approximations, although the graphical models that represent MIMO-ISI channels are fully/densely connected (loopy graphs). These include 1) use of Markov Random Field (MRF) based graphical model with pairwise interaction, in conjunction with {\em message/belief damping}, and 2) use of Factor Graph (FG) based graphical model with {\em Gaussian approximation of interference} (GAI). The per-symbol complexities are $O(K^2n_t^2)$ and $O(Kn_t)$ for the MRF and the FG with GAI approaches, respectively, where $K$ and $n_t$ denote the number of channel uses per frame, and number of transmit antennas, respectively. These low-complexities are quite attractive for large dimensions, i.e., for large $Kn_t$. From a performance perspective, these algorithms are even more interesting in large-dimensions since they achieve increasingly closer to optimum detection performance for increasing $Kn_t$. Also, we show that these message passing algorithms can be used in an iterative manner with local neighborhood search algorithms to improve the reliability/performance of $M$-QAM symbol detection.

description: Archaea are motile by the rotation of the archaellum. The archaellum switches between clockwise and counterclockwise rotation, and movement along a chemical gradient is possible by modulation of the switching frequency. This modulation involves the response regulator CheY and the archaellum adaptor protein CheF. In this study, two new crystal forms and protein structures of CheY are reported. In both crystal forms, CheY is arranged in a domain-swapped conformation. CheF, the protein bridging the chemotaxis signal transduction system and the motility apparatus, was recombinantly expressed, purified and subjected to X-ray data collection.

description: For nearby K dwarfs, the broadening of the observed Main Sequence at low metallicities is much narrower than expected from isochrones with the standard helium-to-metal enrichment ratio DY/DZ=2. Though the latter value fits well the Main Sequence around solar metallicity, and agrees with independent measurements from HII regions as well as with theoretical stellar yields and chemical evolution models, a much higher DY/DZ~10 is necessary to reproduce the broadening observed for nearby subdwarfs. This result resembles, on a milder scale, the very high DY/DZ estimated from the multiple Main Sequences in Omega Cen and NGC 2808. Although not "inverted" as in omega Cen, where the metal-rich Main Sequence is bluer than the metal-poor one, the broadening observed for nearby subdwarfs is much narrower than stellar models predict for a standard helium content. We use this empirical evidence to argue that a revision of lower Main Sequence stellar models, suggested from nearby stars, could significantly reduce the helium content inferred for the subpopulations of those globular clusters. A simple formula based on empirically calibrated homology relations is constructed, for an alternative estimate of DY/DZ in multiple main sequences. We find that, under the most favourable assumptions, the estimated helium content for the enriched populations could decrease from Y~0.4 to as low as Y~0.3.

description: The first measurement of the charged-particle multiplicity density at mid-rapidity in Pb-Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}}$ = 2.76 TeV is presented. For an event sample corresponding to the most central 5% of the hadronic cross section the pseudo-rapidity density of primary charged particles at mid-rapidity is 1584 $\pm$ 4 (stat) $\pm$ 76 (sys.), which corresponds to 8.3 $\pm$ 0.4 (sys.) per participating nucleon pair. This represents an increase of about a factor 1.9 relative to pp collisions at similar collision energies, and about a factor 2.2 to central Au-Au collisions at $\sqrt{s_{\rm NN}}$ = 0.2 TeV. This measurement provides the first experimental constraint for models of nucleus-nucleus collisions at LHC energies.

description: GRAVITY is an adaptive optics assisted Beam Combiner for the second generation VLTI instrumentation. The instrument will provide high-precision narrow-angle astrometry and phase-referenced interferometric imaging in the astronomical K-band for faint objects. We describe the wide range of science that will be tackled with this instrument, highlighting the unique capabilities of the VLTI in combination with GRAVITY. The most prominent goal is to observe highly relativistic motions of matter close to the event horizon of Sgr A*, the massive black hole at center of the Milky Way. We present the preliminary design that fulfils the requirements that follow from the key science drivers: It includes an integrated optics, 4-telescope, dual feed beam combiner operated in a cryogenic vessel; near-infrared wavefrontsensing adaptive optics; fringe-tracking on secondary sources within the field of view of the VLTI and a novel metrology concept. Simulations show that 10 μas astrometry within few minutes is feasible for a source with a magnitude of mK = 15 like Sgr A*, given the availability of suitable phase reference sources (mK = 10). Using the same setup, imaging of mK = 18 stellar sources in the interferometric field of view is possible, assuming a full night of observations and the corresponding UV coverage of the VLTI.

description: 1. Property is an economic category reflecting the state of belonging of a certain good to a certain person and providing opportunity to freely own, use and dispose of it. 2. The economic category of “property” has a legal meaning. The economic category of “property” has the scope of legal regulation. Goods as a component of property have a certain legal regime. Property has different legal forms: private property (belonging to one person) and joint property (belonging to several persons). The owner has the following legal powers: own, use and dispose of the property belonging to him/her. Legal authority of the owner regarding the property may be transferred to another person (in whole or in part). Acquisition of property, its transformation, including termination has legal mediation. All owners are provided with equal conditions for exercising their rights. Ownership right is inviolable. No one can be unlawfully deprived of his/her right or restricted in its exercise. Ownership is binding. The owner shall not use the right of ownership to the prejudice of human rights, freedoms and public interests. Activity of the owner may be limited or terminated only in cases established by law. The state shall not interfere in the exercise of ownership rights by the owner. 3. Law of property. The whole of all legal regulators (provision of law, agreement, custom, judicial act) supporting ownership relations is united in a legal institution - “Law of property”. The law of property determines the legal regime of things, intangible results of creative activity, property rights, other items of civil law, which have a tangible or intangible form of their consolidation in civil circulation. - legal power of the owner over his/her property - individual legal attitude of a person to the thing which he/she considers as the property, - absolute nature of a person`s legal attitude to his/her property. Absoluteness indicates an unlimited number of persons opposed the owner with the obligation of non-interference. Limited power of the owner over the property is limited by the property rights of others in respect of such property.

description: Unique marine sediment cores retrieved from the southwestern slope of the Iceland-Faroe Ridge (IFR), close to the main axis of the Iceland-Scotland Overflow Water (ISOW), revealed prominent sedimentary cycles reflecting near-bottom current dynamics, sediment transport, and deposition, coincident with Dansgaard-Oeschger cycles and deglacial perturbations of the Atlantic Meridional Overturning Circulation. The transition between Greenland Stadials (GSs) and Greenland Interstadials (GIs) follows a distinct, recurring sedimentation pattern. Basaltic (Ti-rich) silts were transported from local volcanic sources by strong bottom currents and deposited during GIs comparable to modern ocean circulation. Finer-grained felsic (K-rich) sediments were deposited during GSs, when Iceland-Scotland Overflow was weak. Possible felsic source areas include British-Ireland and/or Fennoscandian shelf areas. A cyclic sawtooth pattern of bottom current strength is characterized by gradual intensification during GIs followed by a sharp decline toward GSs as is documented at core sites along the flank of Reykjanes Ridge. The cores north of the Faroe Channel instead document the opposite pattern. This suggests that the near-bottom currents along the Reykjanes Ridge are strongly controlled by the flow cascading over the IFR. Heinrich-(like) HS-1 and HS-2, are characterized by the deposition of very fine felsic sediments pointing to weakened bottom currents. Distinct coarse-grained intervals of ice-rafted debris are absent from the sediment records, although pebble- and gravel-sized ice-rafted debris is irregularly distributed throughout the fine sediment matrix. Near-bottom currents are considered to have a major control on the lithogenic sediment deposition southwest of the IFR and further downstream.

Effects of rs3842753 on insulin expression in single beta cells.
Creators: name: Wang, Su
Publisher: name: University of British Columbia
Year: 2020

description: Type 1 diabetes (T1D) is characterized by the autoimmune destruction of insulin-secreting beta-cells. Genetic variations upstream at the insulin (INS) locus contribute to ~10% of T1D heritable risk. Multiple studies showed an association between rs3842753 C/C genotype and T1D susceptibility. Three small studies reported an association between rs3842753 C allele and increased whole pancreas INS expression. To date, no large-scale studies have looked at the effect of those genetic variations on insulin expression at the single cell level. We aligned all available human pancreatic single cell RNA sequencing datasets using STAR and used Samtools mpileup to genotype rs3842753. Using Seurat, we integrated 2315 beta-cells from 13 A/A donors, 23 A/C heterozygous donors, and 35 C/C at-risk donors. The donors included persons with and without type 2 diabetes, but not T1D. We compared variance using Bartlett’s test or Fligner-Killeen test and means using Wilcox Rank Sum, Student-t, ANOVA, or Kruskal-Wallis tests. Per β-cell INS expression mean and variance were significantly higher in females compared with males. In male cells, INS expression appeared to be significantly lower in T2D compared to non-diabetic cells. Comparing across all cells, we found that rs3842753 A/C genotype had the highest INS expression followed by C/C genotype, lastly by A/A genotype. Donor level comparisons between genotypes were not statistically significant. Conversely, within A/C heterozygous β-cells, A allele specific INS expression was higher. This association was consistent at the donor level. Lastly, we examined whole pancreatic islets from a small subset of donors and found no relationship between insulin protein abundance and rs3842753 genotype. Our analysis suggests that in single β-cells, rs3842753 may affect INS variance and expression. The contribution of these differences to T1D risk remains unclear.
Phase transition and structures of the twinned low-temperature phases of (Et4N)[ReS4]

description: The title compound, tetraethylammonium tetrathiorhenate, [(C2H5)4N][ReS4], has, at room temperature, a disordered structure in the space group P63mc (Z = 2, α-phase). A phase transition to the monoclinic space group P21 (Z = 2, γ-phase) at 285 K leads to a pseudo-merohedral twin. The high deviation from the hexagonal metric causes split reflections. However, the different orientations could not be separated, but were integrated using a large integration box. Rapid cooling to 110–170 K produces a metastable β-phase (P63, Z = 18) in addition to the γ-phase. All crystals of the β-phase are contaminated with the γ-phase. Additionally, the crystals of the β-phase are merohedrally twinned. In contrast to the α-phase, the β- and γ-phases do not show disorder.

description: We present an inventory of galaxy bulge types (elliptical galaxy, classical bulge, pseudobulge, and bulgeless galaxy) in a volume-limited sample within the local 11 Mpc volume using Spitzer 3.6 micron and HST data. We find that whether counting by number, star formation rate, or stellar mass, the dominant galaxy type in the local universe has pure disk characteristics (either hosting a pseudobulge or being bulgeless). Galaxies that contain either a pseudobulge or no bulge combine to account for over 80% of the number of galaxies above a stellar mass of 10^9 M_sun. Classical bulges and elliptical galaxies account for ~1/4, and disks for ~3/4 of the stellar mass in the local 11 Mpc. About 2/3 of all star formation in the local volume takes place in galaxies with pseudobulges. Looking at the fraction of galaxies with different bulge types as a function of stellar mass, we find that the frequency of classical bulges strongly increases with stellar mass, and comes to dominate above 10^{10.5} M_sun. Galaxies with pseudobulges dominate at 10^{9.5}-10^{10.5} M_sun. Yet lower-mass galaxies are most likely to be bulgeless. If pseudobulges are not a product of mergers, then the frequency of pseudobulges in the local universe poses a challenge for galaxy evolution models.

description: L’obbiettivo di questo progetto, commissionato dall’istituto ISTePS della SUPSI è quello di integrare sensori di coppia all’interno di un robot antropomorfo progettato dall’istituto con lo scopo di migliorarne il sistema di controllo e permettere una movimentazione più precisa e in automatico. La metodologia utilizzata per la realizzazione del progetto consiste nel suddividere il lavoro in tre fasi. Inizialmente, attraverso lo stato dell’arte, si sono raccolti i dati necessari allo sviluppo del progetto, studiando i vari tipi di sensori di coppia disponibili sul mercato. Sono state, poi, raccolte le richieste del committente e sono state descritte funzioni, prestazioni e limiti dei trasduttori. Nella fase successiva è stato effettuato uno studio del giunto in cui deve essere integrato il sensore. È stata realizzata una versione preliminare dei suoi componenti che è stata in seguito affinata tramite un processo iterativo di modellazione e simulazione ad elementi finiti con lo scopo di raggiungere il design ottimale del sensore. Infine, è stata progettata l’elettronica necessaria al funzionamento del sensore, sviluppando una scheda PCB che permetta di trasferire le informazioni ai driver dei giunti e di conseguenza al controller del robot. I trasduttori sviluppati sono composti da 5 diversi componenti: un elemento elastico, una flangia interna, una esterna, una scheda PCB e due estensimetri. L’elemento elastico ha lo scopo di deformarsi con l’applicazione della coppia consentendo di misurare quest’ultima utilizzando degli estensimetri applicati sui suoi raggi. La flangia interna ha lo scopo di contenere la scheda PCB necessaria per trasferire le informazioni degli estensimetri al driver del giunto. Infine, la flangia esterna ha lo scopo di consentire il fissaggio del sensore al prossimo elemento del robot. titolo documento 2/2 Il sensore progettato rispetta i requisiti prefissati dal committente e ha un costo totale di 1736.83 CHF.

description: We report the first measurement of charged particle elliptic flow in Pb-Pb collisions at 2.76 TeV with the ALICE detector at the CERN Large Hadron Collider. The measurement is performed in the central pseudorapidity region (|$η$|<0.8) and transverse momentum range 0.2< $p_{\rm T}$< 5.0 GeV/$c$. The elliptic flow signal v$_2$, measured using the 4-particle correlation method, averaged over transverse momentum and pseudorapidity is 0.087 $\pm$ 0.002 (stat) $\pm$ 0.004 (syst) in the 40-50% centrality class. The differential elliptic flow v$_2(p_{\rm T})$ reaches a maximum of 0.2 near $p_{\rm T}$ = 3 GeV/$c$. Compared to RHIC Au-Au collisions at 200 GeV, the elliptic flow increases by about 30%. Some hydrodynamic model predictions which include viscous corrections are in agreement with the observed increase.

Nowcasting and Predicting the Kp Index Using Historical Values and Real-Time Observations

Publisher: name: FID GEO
Year: 2019

description: Current algorithms for the real-time prediction of the Kp index use a combination of models empirically driven by solar wind measurements at the L1 Lagrange point and historical values of the index. In this study, we explore the limitations of this approach, examining the forecast for short and long lead times using measurements at L1 and Kp time series as input to artificial neural networks. We explore the relative efficiency of the solar wind-based predictions, predictions based on recurrence, and predictions based on persistence. Our modeling results show that for short-term forecasts of approximately half a day, the addition of the historical values of Kp to the measured solar wind values provides a barely noticeable improvement. For a longer-term forecast of more than 2 days, predictions can be made using recurrence only, while solar wind measurements provide very little improvement for a forecast with long horizon times. We also examine predictions for disturbed and quiet geomagnetic activity conditions. Our results show that the paucity of historical measurements of the solar wind for high Kp results in a lower accuracy of predictions during disturbed conditions. Rebalancing of input data can help tailor the predictions for more disturbed conditions.

One reason these patterns of direct connections are critical is that they establish the pathways through which elements influence each other indirectly. Here, we tested a hypothesized consequence of connectivity in ecosystems: the homogenization of resource distributions in flow networks. Specifically, we tested the generality of the systems ecology hypothesis of resource homogenization in 50 empirically derived trophic ecosystem models representing 35 distinct ecosystems. We applied Ecological Network Analysis to calculate resource homogenization for these models. We further evaluated the robustness of our results in two ways. First, we verified the close correspondence between the input- and output-oriented homogenization values to ensure that our results were not biased by our decision to focus on the output orientation. Second, we conducted a Monte Carlo based uncertainty analysis to determine the robustness of our results to +/-5% error introduced into the original flow matrices for each model. Our results show that resource homogenization occurs universally in the 50 ecosystem models tested. We confirm that our results are not biased by using the output-oriented homogenization values because there is a significant linear regression between the input and output oriented homogenization (r^2 = 0.38, p < 0.001). Finally, we found that our results are robust to +/-5% error in the flow matrices. In conclusion, we found strong support for the resource homogenization hypothesis in 50 empirically derived ecosystem models.

description: Different numerical mappings of the DNA sequences have been studied using a new cluster-scaling method and the well known spectral methods. It is shown, in particular, that the nucleotide sequences in DNA molecules have robust cluster-scaling properties. These properties are relevant to both types of nucleotide pair-bases interactions: hydrogen bonds and stacking interactions. It is shown that taking into account the cluster-scaling properties can help to improve heterogeneous models of the DNA dynamics. It is also shown that a chaotic (deterministic) order, rather than a stochastic randomness, controls the energy minima positions of the stacking interactions in the DNA sequences on large scales. The chaotic order results in a large-scale chaotic coherence between the two complimentary DNA-duplex's sequences. A competition between this broad-band chaotic coherence and the resonance coherence produced by genetic code has been briefly discussed. The Arabidopsis plant genome (which is a model plant for genome analysis) and two human genes: BRCA2 and NRXN1, have been considered as examples.

Lithospheric Delamination Beneath the Southern Puna Plateau Resolved by Local Earthquake Tomography

description: We present a local earthquake tomography to illuminate the crustal and uppermost mantle structure beneath the southern Puna plateau and to test the delamination hypothesis. Vp and Vp/Vs ratios were obtained using travel time variations recorded by 75 temporary seismic stations between 2007 and 2009. In the upper crust, prominent low Vp anomalies are found beneath the main volcanic centers, indicating the presence of magma and melt beneath the southern Puna plateau. Beneath the Moho at around 90-km depth, a strong high Vp anomaly is detected just west of the giant backarc Cerro Galan ignimbrite caldera. This high Vp anomaly is only resolved if earthquakes with an azimuthal gap up to 300° are included in the inversion. However, we show through data subset and synthetic tests that the anomaly is robust due to our specific station-event geometry and interpret it as a delaminated block of lower crust and uppermost mantle lithosphere under the southern Puna plateau. The low velocities in the crust are interpreted as a product of the delamination event that triggered the rise of fluids and melts into the crust and induced the high topography in this part of the plateau. The tomography also reveals the existence of low-velocity anomalies that link arc magmatism at the Ojos del Salado volcanic center with slab seismicity clusters at depths of about 100 and 150 km and support fluid transport in the mantle wedge due to dehydration reaction within the subducted slab.

description: We report the discovery of WASP-26b, a moderately over-sized Jupiter-mass exoplanet transiting its 11.3-magnitude early-G-type host star (1SWASP J001824.70-151602.3; TYC 5839-876-1) every 2.7566 days. A simultaneous fit to transit photometry and radial-velocity measurements yields a planetary mass of 1.02 +/- 0.03 M_Jup and radius of 1.32 +/- 0.08 R_Jup. The host star, WASP-26, has a mass of 1.12 +/- 0.03 M_sun and a radius of 1.34 +/- 0.06 R_sun and is in a visual double with a fainter K-type star. The two stars are at least a common-proper motion pair with a common distance of around 250 +/- 15 pc and an age of 6 +/- 2 Gy.

Effects of finite temperature on the robustness of the Mott insulator phase in pseudo one-dimensional Bose-Hubbard Model

description: We study the superfluid-Mott insulator (SF-MI) transition in an one-dimensional optical lattice system, and employ the Bose-Hubbard model in two dimension with a combined potential of an optical lattice in one direction and a confining harmonic trap in the other direction, which we refer to as the pseudo one-dimension Bose-Hubbard model. There some excited states with respect to the harmonic trap are considered. The Mott lobes shrink in the $μ$ and $J$ directions of the $μ$-$J$ phase diagram. The shrinkage occurs because the interactions involving the excited states become weaker than that between particles in the ground state. The dispersion of the in-site particle increases because the energy spacing between the eigenstates of the Hamiltonian decreases at finite temperature. The excited states significantly affect the robustness of the MI phase at finite temperate.

description: Abstract Objectives Paleofeces are valuable to archeologists and evolutionary biologists for their potential to yield health, dietary, and host information. As a rich source of preserved biomolecules from host-associated microorganisms, they can also provide insights into the recent evolution and changing ecology of the gut microbiome. However, there is currently no standard method for DNA extraction from paleofeces, which combine the dual challenges of complex biological composition and degraded DNA. Due to the scarcity and relatively poor preservation of paleofeces when compared with other archeological remains, it is important to use efficient methods that maximize ancient DNA (aDNA) recovery while also minimizing downstream taxonomic biases. Methods In this study, we use shotgun metagenomics to systematically compare the performance of five DNA extraction methods on a set of well-preserved human and dog paleofeces from Mexico (~1,300 BP). Results Our results show that all tested DNA extraction methods yield a consistent microbial taxonomic profile, but that methods optimized for ancient samples recover significantly more DNA. Conclusions These results show promise for future studies that seek to explore the evolution of the human gut microbiome by comparing aDNA data with those generated in modern studies.
Understanding the role of neuronal cell fate determinants in synapse pattern formation in C. elegans
Creators: name: Kurashina, Mizuki
Publisher: name: University of British Columbia
Year: 2020

description: Animal locomotion and behaviour are ultimately controlled by the precise neuronal circuit formation at the level of synaptic connection. Mutations in the genes that specify individual neuronal cell fate (or cell fate determinants) alter synaptic connections and circuit wiring which results in the malfunction of the nervous system. It is however not fully understood if the defects in these mutants are merely due to a consequence of cell fate transformation, or the cell fate determinants have specific functions in synapse pattern formation. Here we identify a novel role for a homeobox transcription factor UNC-4 and its co-repressor UNC-37/Groucho, in tiled synapse pattern formation of the cholinergic motor neurons (DA8 and DA9) in Caenorhabditis elegans. In unc-4 and unc-37 mutant animals, we observed large overlap between the synaptic domains of DA8 and DA9. Strikingly, we show using temperature-sensitive mutants and auxin-inducible degron system that unc-4 is not required during embryonic development when DA neurons cell fate is set but is required post-embryonically. In contrast, unc-37 is required embryonically and post-embryonically in DA neurons for a tiled synaptic innervation. Our result reveals a novel post-cell fate determination role of homeobox gene in neuronal pattern formation.
