description: Van der Waals magnets have emerged as a fertile ground for the exploration of highly tunable spin physics and spin-related technology. Two-dimensional (2D) magnons in van der Waals magnets are collective excitation of spins under strong confinement. Although considerable progress has been made in understanding 2D magnons, a crucial magnon device called the van der Waals magnon valve, in which the magnon signal can be completely and repeatedly turned on and off electrically, has yet to be realized. Here we demonstrate such magnon valves based on van der Waals antiferromagnetic insulator MnPS3. By applying DC electric current through the gate electrode, we show that the second harmonic thermal magnon (SHM) signal can be tuned from positive to negative. The guaranteed zero crossing during this tuning demonstrates a complete blocking of SHM transmission, arising from the nonlinear gate dependence of the non-equilibrium magnon density in the 2D spin channel. Using the switchable magnon valves we demonstrate a magnon-based inverter. These results illustrate the potential of van der Waals anti-ferromagnets for studying highly tunable spin-wave physics and for application in magnon-base circuitry in future information technology.

description: We present an efficient method of reconstructing the parameters of the Constrained MSSM from assumed future LHC data, applied both on their own right and in combination with the cosmological determination of the relic dark matter abundance. Focusing on the ATLAS SU3 benchmark point, we demonstrate that our simple Gaussian approximation can recover the values of its parameters remarkably well. We examine two popular non-informative priors and obtain very similar results, although when we use an informative, naturalness-motivated prior, we find some sizeable differences. We show that a further strong improvement in reconstructing the SU3 parameters can by achieved by applying additional information about the relic abundance at the level of WMAP accuracy, although the expected data from Planck will have only a very limited additional impact. Further external data may be required to break some remaining degeneracies. We argue that the method presented here is applicable to a wide class of low-energy effective supersymmetric models, as it does not require to deal with purely experimental issues, eg, detector performance, and has the additional advantages of computational efficiency. Furthermore, our approach allows one to distinguish the effect of the model's internal structure and of the external data on the final parameters constraints.

title: Dynamik und Modellierung aktiver Verteilnetze unter Berücksichtigung netzbildender Regelung
Creators: name: Coumont, Martin Albrecht
Publisher: name: UNSPECIFIED
Year: 2022

description: Die Energiewende führt zu einem starken Anstieg dezentraler Erzeugungsanlagen. Diese sind zu großen Teilen leistungselektronisch mit den Verteilnetzen gekoppelt. Die Verteilnetze wandeln sich zu aktiven Verteilnetzen. Für die Zukunft ist zu erwarten, dass sich ein Teil dieser Erzeugungsanlagen netzbildend verhält, um wichtige Beiträge zur Netzregelung erbringen zu können. Hierbei ist zum einen zu klären, welchen Einfluss dieses netzbildende Verhalten auf die Dynamik in Verteilnetzen und speziell auf die Kurzzeitdynamik bei Großsignalanregungen ausübt. Zum anderen wird es immer stärker notwendig, aktive Verteilnetze bei Studien zur Systemstabilität im Übertragungsnetz zu berücksichtigen. Eine Möglichkeit dafür besteht in der Aggregation von Netzabschnitten durch dynamische Netzäquivalente. Diese Ansätze berücksichtigen derzeit allerdings ausschließlich netzfolgendes Verhalten von Erzeugungsanlagen. Die vorliegende Arbeit adressiert beide Punkte und analysiert zunächst den Einfluss von dezentralen Erzeugungsanlagen mit VSC-Umrichtern auf die Kurzzeit-Spannungsstabilität in Verteilnetzen. Hierzu werden verschiedene Regelstrategien mit netzfolgenden und netzbildenden Merkmalen durch numerische Simulationen im Zeitbereich verglichen. Es wird gezeigt, dass netzbildendes Verhalten einen geringen positiven Einfluss auf die Kurzzeit-Spannungsstabilität hat. Dieser ist stärker in schwachen Netzen und an den Enden von Abgängen ausgeprägt. Anschließend wird ein Ersatzmodell für Erzeugungsanlagen mit VSC-Umrichtern erarbeitet, das sowohl die Kurzzeitdynamik von netzfolgendem als auch von netzbildendem Verhalten wiedergeben kann. Es wird demonstriert, dass dieses Ersatzmodell als Teil eines dynamischen Netzäquivalents für aktive Verteilnetze verwendet werden kann. Zur Bildung des dynamischen Netzäquivalents wird ein messwertbasierter Ansatz verwendet. Anhand von Untersuchungen mit unterschiedlich geregelten Erzeugungsanlagen wird der Ansatz validiert. Es wird gezeigt, dass sowohl Abgänge mit netzfolgenden Anlagen als auch Abgänge mit netzbildenden Anlagen durch das Netzäquivalent aggregiert werden können. Mit reduzierter Genauigkeit können auch Netzabschnitte aggregiert werden, in denen Anlagen mit unterschiedlichem Verhalten enthalten sind.

description: An elicitor chitosan (CHT) induces stomatal closure but the mechanism remains to be clarified. A phytohormone salicylic acid (SA) is crucial for elicitor-induced defense signaling in plants. Here we investigated whether endogenous SA is required for CHT signaling in guard cells. In the SA-deficient nahG mutant, treatment of CHT did not induce either apoplastic reactive oxygen species (ROS) production or stomatal closure but co-treatment of CHT and SA induced both apoplastic ROS production and stomatal closure, indicating the involvement of endogenous SA in CHT-induced apoplastic ROS production and CHT-induced stomatal closure. Furthermore, CHT induced transient cytosolic free calcium concentration increments in the nahG mutant in the presence of exogenous SA but not in the absence of exogenous SA. These results provide evidence that endogenous SA is a crucial element in CHT-induced stomatal closure.

description: Fermilab operates the world's most intense antiproton source. Newly proposed experiments can use those antiprotons either parasitically during Tevatron Collider running or after the Tevatron Collider finishes in about 2011. For example, the annihilation of 8 GeV antiprotons might make the world's most intense source of tagged D^0 mesons, and thus the best near-term opportunity to study charm mixing and, via CP violation, to search for new physics. Other potential measurements include sensitive studies of hyperons and of the mysterious X, Y, and Z states. Production of antihydrogen in flight can be used for first searches for antihydrogen CPT violation. With antiproton deceleration to low energy, an experiment using a Penning trap and an atom interferometer could make the world's first measurement of the gravitational force on antimatter.

description: Results for the naive-time-reversal-odd quark distributions in a light-cone quark model are presented. The final-state interaction effects are generated via single-gluon exchange mechanism. The formalism of light-cone wave functions is used to derive general expressions in terms of overlap of wave-function amplitudes describing the different orbital angular momentum components of the nucleon. In particular, the model predictions show a dominant contribution from S- and P-wave interference in the Sivers function and a significant contribution also from the interference of P and D waves in the Boer-Mulders function. The favourable comparison with existing phenomenological parametrizations motivates further applications to describe azimuthal asymmetries in hadronic reactions.

description: Seshadri constants express the so called local positivity of a line bundle on a projective variety. They were introduced by Demailly. The original idea of using them towards a proof of the Fujita conjecture failed but they quickly became a subject of intensive study quite in their own right. Lazarsfeld's book "Positivity in Algebraic Geometry" contains a whole chapter devoted to local positivity and serves as a very enjoyable introduction to Seshadri constants. Since this book has appeared, the subject witnessed quite a bit of development. It is the aim of these notes to give an account of recent progress as well as to discuss many open questions and provide some examples.

description: Different approaches to quantum gravity converge in predicting the existence of a minimal scale of length. This raises the fundamental question as to whether and how an intrinsic limit to spatial resolution can affect quantum mechanical observables associated to internal degrees of freedom. We answer this question in general terms by showing that the spin operator acquires a momentum-dependent contribution in quantum mechanics equipped with a minimal length. Among other consequences, this modification induces a form of quantum nonlocality stronger than the one arising in ordinary quantum mechanics. In particular, we show that violations of the Bell inequality can exceed the maximum value allowed in ordinary quantum mechanics, the so-called Tsirelson bound, by a positive-valued function of the momentum operator. We introduce possible experimental settings based on neutron interferometry and quantum contextuality, and we provide preliminary estimates on the values of the physical parameters needed for actual laboratory implementations.
Hydrogenation of ∝- oximinoglutaric acid on Raney Nickel : studies toward optical resolution
Creators: name: McGinnis, Michael J.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes physicochemical studies to investigate a report of spontaneous optical resolution in the hydrogenation of ∝-ketoglutaric acid and its oxime by some Japanese workers in l958. Since the intention was to study the kinetics of the reaction, a rapid method for quantitative analysis of reactant and product in aqueous solution was required, and a large part of the thesis is concerned with the development of suitable analytical methods. For the reduction of the ketoacid, several methods were studied and all found unsuitable. For the production of glutamic acid from the oxime, a method using the reaction of the aminoacid with ninhydrin was quite successful. The hydrogenations were catalysed by Raney Nickel, and the work required study of the surface area of the catalyst and of its characteristics for competitive adsorption of reactant, product and phosphate buffer from the reaction mixture. The kinetic studies showed rather low reproducibility. In a number of cases, the reaction proceeded in a markedly autocatalytic manner, giving product in proportion to the square of the time. In other cases, the reaction curve was close to linear (zero-order). Except in one case which gave an optical effect of marginal significance, no spontaneous resolution was observed, neither could optical resolution be induced by doping the system with an enantiomer of the product. I conclude that autocatalytic behavior which might provide the necessary conditions for spontaneous resolution occurs in the hydrogenation, but that my results do not substantiate the Japanese workers' claim that spontaneous resolution occurs.

description: We here present the luminosity function (LF) of globular clusters (GCs) in five nearby spiral galaxies using the samples of GC candidates selected in Hubble Space Telescope mosaic images in F435W, F555W and F814W filters. Our search, which surpasses the fractional area covered by all previous searches in these galaxies, has resulted in the detection of 158 GC candidates in M81, 1123 in M101, 226 in NGC4258, 293 in M51 and 173 in NGC628. The LFs constructed from this dataset, after correcting for relatively small contamination from reddened young clusters, are log-normal in nature, which was hitherto established only for the Milky Way (MW) and Andromeda among spiral galaxies. The magnitude at the turn-over (TO) corresponds to Mv(TO)=-7.41+/-0.14 in four of the galaxies with Hubble types Sc or earlier, in excellent agreement with Mv(TO)=-7.40+/-0.10 for the MW. The TO magnitude is equivalent to a mass of ~3x10^5 Msun for an old, metal-poor population. Mv(TO) is fainter by ~1.16 magnitude for the fifth galaxy, M101, which is of Hubble type Scd. The TO dependence on Hubble type implies that the GCs in early-type spirals are classical GCs, which have a universal TO, whereas the GC population in late-type galaxies is dominated by old disk clusters, which are in general less massive. The radial density distribution of GCs in our sample galaxies follows the Sérsic function with exponential power-law indices, and effective radii of 4.0-9.5 kpc. GCs in the sample galaxies have a mean specific frequency of 1.10+/-0.24, after correcting for magnitude and radial incompleteness factors.

description: The natural coagulant Moringa oleifera lectin (MoL) as cationic protein is a promising candidate in coagulation process of water treatment plant. Introducing the gene encoding MoL into a host, Pichia pastoris, to secrete soluble recombinant protein is assessed in this study. Initial screening using PCR confirmed the insertion of MoL gene, and SDS-PAGE analysis detected the MoL protein at 8 kDa. Cultured optimization showed the highest MoL protein at 520 mg/L was observed at 28 °C for 144 h of culturing by induction in 1% methanol. Approximately, 0.40 mg/mL of recombinant MoL protein showed 95 ± 2% turbidity removal of 1% kaolin suspension. In 0.1% kaolin suspension, the concentration of MoL at 10 μg/mL exhibits the highest turbidity reduction at 68 ± 1%. Thus, recombinant MoL protein from P. pastoris is an effective coagulant for water treatment.

Transport infrastructure and economic development in least

Subjects: SECS-P/01 Economia politica

description: This PhD thesis tries to show the impact of transport infrastructure in economic development in least developed countries and in particular in the case of Afghanistan. Some least developed countries during 1990 to 1999 experienced lack of investment in transportation. Lack of
investment further increased the economic development gap between developed and least developed countries. Moreover, lack of literature and research in poor countries such as
Afghanistan encouraged me to do my research in this country in order to unveil the problems, facing poor people who are living in inaccessible places and suffer from lack of economic opportunities and long term unemployment. This thesis shows the effect of inaccessibility and immobility in economic opportunities and basic social services in Afghanistan. This thesis is important because it covers the role of transport infrastructures at the moment that international community promised to rebuild the infrastructures of post conflict Afghanistan.

description: We report the discovery of a highly-polarized, highly-variable, steep-spectrum radio source, ASKAP J173608.2-321635, located $\sim$4\,deg from the Galactic center in the Galactic plane. The source was detected six times between 2020 January and 2020 September as part of the Australian Square Kilometre Array Pathfinder Variables and Slow Transients (ASKAP VAST) survey at 888\,MHz. It exhibited a high degree ($\sim 25$\%) of circular polarization when it was visible. We monitored the source with the MeerKAT telescope from 2020 November to 2021 February on a 2--4 week cadence. The source was not detected with MeerKAT before 2021 February 07 when it appeared and reached a peak flux density of 5.6\,mJy. The source was still highly circularly polarized, but also showed up to 80\% linear polarization, and then faded rapidly with a timescale of one day. The rotation measure of the source varied significantly, from $-11.8\pm0.8$\,rad\,m$^{-2}$ to $-64.0\pm1.5$\,rad\,m$^{-2}$, over three days. No X-ray counterpart was found in follow-up \textit{Swift} or \textit{Chandra} observations about a week after the first MeerKAT detection, with upper limits of $\sim 5.0\times10^{31}$\,erg\,s$^{-1}$ (0.3--8\,keV, assuming a distance $\sim10$ kpc). No counterpart is seen in new or archival near-infrared observations down to $J=20.8$\,mag. We discuss possible identifications for ASKAP J173608.2-321635 including a low-mass star/substellar object with extremely low infrared luminosity, a pulsar with scatter-broadened pulses, a transient magnetar, or a Galactic Center Radio Transient: none of these fully explains the observations, which suggests that ASKAP J173608.2-321635 may represent part of a new class of objects being discovered through radio imaging surveys.

The microwave spectra of propiolamide
Creators: name: Little, Gary Bruce
Publisher: name: University of British Columbia
Year: 2010

description: The ground vibrational state microwave spectra of propiolamide, HCCCONH₂, and two isotopically-substituted species, HCCCOND₂ and DCCCOND₂, have been assigned in the frequency region 8-40 GHz and the rotational, centrifugal distortion and ¹⁴N nuclear quadrupole coupling constants have been determined. The spectra for three excited vibrational states of HCCCONH₂, the in- and out-of-plane C≡C-C bending modes and the nitrogen inversion mode, have also been analyzed; the vibrational frequencies, as determined by relative intensity measurements, are 273±75 cm⁻¹, >273 cm⁻¹ and 333±75 cm⁻¹, respectively. The molecule has been shown to be essentially planar with either no barrier to the inversion motion or only a very small one. This result is based mainly on the small change in the ground state inertial defect upon amido-group deuteration (Δ(HCCCOND₂)- Δ(HCCCONH₂)=-0.0311 amu-A²), the high frequency of the inversion motion, the absence of c-type transitions in the spectra, the similarity of the distortion constants in the ground and first excited inversion states and the small magnitude of X[sub cc]. Thus it is concluded that the planar resonance form of propiolamide, H-C≡C-C(O⁻)H⁺₂, is making the only significant contribution to the state of the molecule. Internuclear parameters of propiolamide have been determined by the substitution method and no anomalies have been found. Stark effect measurements have yielded a value of 3.67±0.02 D for the electricdipole moment (μ[sub a] =1.08+0.02 D, μ[sub b] =3.51+0.02 D) and it has been deduced to be directed between the C-C and C=0 bonds at an angle of ≃11° to the latter.

description: The research presented in my PhD thesis is part of a wider European project, FishPopTrace, focused on traceability of fish populations and products. My work was aimed at developing and analyzing novel genetic tools for a widely distributed marine fish species, the European hake (Merluccius merluccius), in order to investigate population genetic structure and explore potential applications to traceability scenarios. 
A total of 395 SNPs (Single Nucleotide Polymorphisms) were discovered from a massive collection of Expressed Sequence Tags, obtained by high-throughput sequencing, and validated on 19 geographic samples from Atlantic and Mediterranean. 
Genome-scan approaches were applied to identify polymorphisms on genes potentially under divergent selection (outlier SNPs), showing higher genetic differentiation among populations respect to the average observed across loci. Comparative analysis on population structure were carried out on putative neutral and outlier loci at wide (Atlantic and Mediterranean samples) and regional (samples within each basin) spatial scales, to disentangle the effects of demographic and adaptive evolutionary forces on European hake populations genetic structure. Results demonstrated the potential of outlier loci to unveil fine scale genetic structure, possibly identifying locally adapted populations, despite the weak signal showed from putative neutral SNPs.
The application of outlier SNPs within the framework of fishery resources management was also explored. A minimum panel of SNP markers showing maximum discriminatory power was selected and applied to a traceability scenario aiming at identifying the basin (and hence the stock) of origin, Atlantic or Mediterranean, of individual fish. This case study illustrates how molecular analytical technologies have operational potential in real-world contexts, and more specifically, potential to support fisheries control and enforcement and fish and fish product traceability.

description: Trehalose 6-phosphate phosphorylase (TrePP), a member of glycoside hydrolase family 65, catalyzes the reversible phosphorolysis of trehalose 6-phosphate (Tre6P) with inversion of the anomeric configuration to produce β-d-glucose 1-phosphate (β-Glc1P) and d-glucose 6-phosphate (Glc6P). TrePP in Lactococcus lactis ssp. lactis (LlTrePP) is, alongside the phosphotransferase system, involved in the metabolism of trehalose. In this study, recombinant LlTrePP was produced and characterized. It showed its highest reverse phosphorolytic activity at pH 4.8 and 40°C, and was stable in the pH range 5.0–8.0 and at up to 30°C. Kinetic analyses indicated that reverse phosphorolysis of Tre6P proceeded through a sequential bi bi mechanism involving the formation of a ternary complex of the enzyme, β-Glc1P, and Glc6P. Suitable acceptor substrates were Glc6P, and, at a low level, d-mannose 6-phosphate (Man6P). From β-Glc1P and Man6P, a novel sugar phosphate, α-d-Glcp-(1↔1)-α-d-Manp6P, was synthesized with 51% yield. A novel sugar phosphate, α-d-Glcp-(1↔1)-α-d-Manp6P, was synthesized by Lactococcus lactis ssp. lactis trehalose 6-phosphate phosphorylase.
Explorations into the Viability of Coupled Radius-Orbit Evolutionary Models for Inflated Planets

description: The radii of some transiting extrasolar giant planets are larger than would be expected by the standard theory. We address this puzzle with the model of coupled radius-orbit tidal evolution developed by \citet{Ibgui_and_Burrows_2009}. The planetary radius is evolved self-consistently with orbital parameters, under the influence of tidal torques and tidal dissipation in the interior of the planet. A general feature of this model, which we have previously demonstrated in the generic case, is that a possible transient inflation of the planetary radius can temporarily interrupt its standard monotonic shrinking and can lead to the inflated radii that we observe. In particular, a bloated planet with even a circular orbit may still be inflated due to an earlier episode of tidal heating. We have modified our model to include an orbital period dependence of the tidal dissipation factor in the star, $Q'_{\ast} \propto P^γ$, $-1 \leqslant γ\leqslant 1$. With this model, we search, for a tidally heated planet, orbital and radius evolutionary tracks that fall within the observational limits of the radius, the semimajor axis, and the eccentricity of the planet in its current estimated age range. We find that, for some inflated planets (WASP-6b and WASP-15b), there are such tracks; for another (TrES-4), there are none; and for still others (WASP-4b and WASP-12b), there are such tracks, but our model might imply that we are observing the planets at a special time. Finally, we stress that there is a two to three order-of-magnitude timescale uncertainty of the inspiraling phase of the planet into its host star, arising from uncertainties in the tidal dissipation factor in the star $Q'_{\ast}$.

description: Starting from an ultracold sample of ground-state $^{23}$Na$^{87}$Rb molecules, we investigate the lowest ro-vibrational level of the $b^3Π$ state with high resolution laser spectroscopy. This electronic spin-forbidden $X^1Σ^+ \leftrightarrow b^3Π$ transition features a nearly diagonal Franck-Condon factor and has been proposed useful for probing and manipulating the ultracold molecular gas. We measure the transition strength directly by probing the ac Stark shift induced by near resonance light and determine the total excited-state spontaneous emission rate by observing the loss of molecules. From the extracted branching ratio and the theoretical modeling, we find that the leakage to the continuum of the $a^3Σ^+$ state plays the dominant role in the total transition linewidth. Based on these results, we show that it is feasible to create optical trapping potentials for maximizing the rotational coherence with laser light tuned to near this transition.

L1-Penalized Quantile Regression in High-Dimensional Sparse Models

description: We consider median regression and, more generally, a possibly infinite collection of quantile regressions in high-dimensional sparse models. In these models the overall number of regressors $p$ is very large, possibly larger than the sample size $n$, but only $s$ of these regressors have non-zero impact on the conditional quantile of the response variable, where $s$ grows slower than $n$. We consider quantile regression penalized by the $\ell_1$-norm of coefficients ($\ell_1$-QR). First, we show that $\ell_1$-QR is consistent at the rate $\sqrt{s/n} \sqrt{\log p}$. The overall number of regressors $p$ affects the rate only through the $\log p$ factor, thus allowing nearly exponential growth in the number of zero-impact regressors. The rate result holds under relatively weak conditions, requiring that $s/n$ converges to zero at a super-logarithmic speed and that regularization parameter satisfies certain theoretical constraints. Second, we propose a pivotal, data-driven choice of the regularization parameter and show that it satisfies these theoretical constraints. Third, we show that $\ell_1$-QR correctly selects the true minimal model as a valid submodel, when the non-zero coefficients of the true model are well separated from zero. We also show that the number of non-zero coefficients in $\ell_1$-QR is of same stochastic order as $s$. Fourth, we analyze the rate of convergence of a two-step estimator that applies ordinary quantile regression to the selected model. Fifth, we evaluate the performance of $\ell_1$-QR in a Monte-Carlo experiment, and illustrate its use on an international economic growth application.

description: Landslides are destructive and recurrent natural disasters on steep slopes and represent a risk to lives and properties. Knowledge of relict landslides location is vital to understand their mechanisms, update inventory maps and improve risk assessment. However, relict landslide mapping is complex in tropical regions covered with rainforest vegetation. A new CNN framework is proposed for semi-automatic detection of relict landslides, which uses a dataset generated by a k-means clustering algorithm and has a pre-training step. The weights computed in the pre-training are used to fine-tune the CNN training process. A comparison between the proposed and the standard framework is performed using CBERS-04A WPM images. Three CNNs for semantic segmentation are used (Unet, FPN, Linknet) with two augmented datasets. A total of 42 combinations of CNNs are tested. Values of precision and recall were very similar between the combinations tested. Recall was higher than 75% for every combination, but precision values were usually smaller than 20%. False positives (FP) samples were addressed as the cause for these low precision values. Predictions of the proposed framework were more accurate and correctly detected more landslides. This work demonstrates that there are limitations for detecting relict landslides in areas covered with rainforest, mainly related to similarities between the spectral response of pastures and deforested areas with Gleichenella sp. ferns, commonly used as an indicator of landslide scars.

description: Websites are regarded as domains of limitless information which anyone and everyone can access. The new trend of technology put us to change the way we are doing our business. The Internet now is fastly becoming a new place for business and the advancement in this technology gave rise to the number of e-commerce websites. This made the lifestyle of marketers/vendors, retailers and consumers (collectively regarded as users in this paper) easy, because it provides easy platforms to sale/order items through the internet. This also requires that the users will have to spend a lot of time and effort to search for the best product deals, products updates and offers on e-commerce websites. They have to filter and compare search results by themselves which takes a lot of time and there are chances of ambiguous results. In this paper, we applied web crawling and scraping methods on an e-commerce website to get HTML data for identifying products updates based on the current time. The HTML data is preprocessed to extract details of the products such as name, price, post date and time, etc. to serve as useful information for users.
