description: Violent relaxation -- the protocluster dynamical response to the expulsion of its residual star forming gas -- is a short albeit crucial episode in the evolution of star clusters and star cluster systems. Because it is heavily driven by cluster formation and environmental conditions, it is a potentially highly rewarding phase in terms of probing star formation and galaxy evolution. In this contribution I review how cluster formation and environmental conditions affect the shape of the young cluster mass function and the relation between the present star formation rate of galaxies and the mass of their young most massive cluster.

description: We propose models of twisted multilayer graphene that exhibit exactly flat Bloch bands with arbitrary Chern numbers and ideal band geometries. The models are constructed by twisting two sheets of Bernal-stacked multiple graphene layers with only inter-sublattice couplings. Analytically we show that flatband wavefunctions in these models exhibit a momentum space holomorphic character, leading to ideal band geometries. We also explicitly demonstrate a generic "wavefunction exchange" mechanism that generates the high Chern numbers of these ideal flatbands. The ideal band geometries and high Chern numbers of the flatbands imply the possibility of hosting exotic fractional Chern insulators which do not have analogues in continuum Landau levels. We numerically verify that these exotic fractional Chern insulators are model states for short-range interactions, characterized by exact ground-state degeneracies at zero energy and infinite particle-cut entanglement gaps.

description: Magnon-polaritons (MPs) refer to a light--magnon coupled state and can potentially act as information carriers, possibly enabling charge-free computation. However, the light--magnon coupling is inherently weak. To achieve sufficiently strong coupling, a large ferromagnet or coupling with a microwave cavity is necessary. Herein, we theoretically propose a fundamental platform for magnonic and magnon--optical information storage devices and discuss the transport properties of MP's. The proposed multi-layered structure overcomes the aforementioned issues. Owing to the waveguide modes, magnons placed in a nanometer-thin layer are strongly coupled with light, exhibiting rich functionalities of thick-layer MPs via the `magnetic antenna effect'. Thus, the thin-layer MPs are faster, and the direction is switchable. The results of this study will enable the integration of ferromagnetic micro and nanostructures for MP-based information devices without any restrictions due to cavities.

description: In our recent works [R. Szmytkowski, J. Phys. A 39 (2006) 15147; corrigendum: 40 (2007) 7819; addendum: 40 (2007) 14887], we have investigated the derivative of the Legendre function of the first kind, $P_ν(z)$, with respect to its degree $ν$. In the present work, we extend these studies and construct several representations of the derivative of the associated Legendre function of the first kind, $P_ν^{\pm m}(z)$, with respect to the degree $ν$, for $m\in\mathbb{N}$. At first, we establish several contour-integral representations of $\partial P_ν^{\pm m}(z)/\partialν$. They are then used to derive Rodrigues-type formulas for $[\partial P_ν^{\pm m}(z)/\partialν]_{ν=n}$ with $n\in\mathbb{N}$. Next, some closed-form expressions for $[\partial P_ν^{\pm m}(z)/\partialν]_{ν=n}$ are obtained. These results are applied to find several representations, both explicit and of the Rodrigues type, for the associated Legendre function of the second kind of integer degree and order, $Q_{n}^{\pm m}(z)$; the explicit representations are suitable for use for numerical purposes in various regions of the complex $z$-plane. Finally, the derivatives $[\partial^{2}P_ν^{m}(z)/\partialν^{2}]_{ν=n}$, $[\partial Q_ν^{m}(z)/\partialν]_{ν=n}$ and $[\partial Q_ν^{m}(z)/\partialν]_{ν=-n-1}$, all with $m>n$, are evaluated in terms of $[\partial P_ν^{-m}(\pm z)/\partialν]_{ν=n}$.

description: Strong magnetic fields profoundly affect the quantum physics of charged particles, as seen for example by the integer and fractionally quantized Hall effects, and the fractal `Hofstadter butterfly' spectrum of electrons in the presence of a periodic potential and a magnetic field. Intrinsic physics can lead to effects equivalent to those produced by an externally applied magnetic field. Examples include the `staggered flux' phases emerging in some theories of quantum spin liquids and the Chern insulator behavior of twisted bilayer graphene when valley symmetry is broken. In this paper we show that when two layers of the transition metal dichalcogenide material WSe2 are stacked at a small relative twist angle to form a Moire bilayer, the resulting low energy physics can be understood in terms of electrons moving in a strong and tunable staggered flux. We predict experimental consequences including sign reversals of the Hall coefficient on application of an interlayer potential and spin currents appearing at sample edges and interfaces.

The uptake of sulphur, calcium, and magnesium and their distribution in Phaseolus vulgaris L. as affected by cyclohexanecarboxylic acid
Creators: name: Peirson, David Robert
Publisher: name: University of British Columbia
Year: 2011

description: Cyclohexanecarboxylic acid (CHCA) has one of the lowest molecular weights of the naphthenic acids, a group of compounds which have been recognized recently as stimulators of plant growth and metabolism. Potassium cyclohexanecarboxy-late's (KCHC) effects on the mineral nutrition of bush bean plants (Phaseolus vulgaris L., cultivar Top Crop) were examined in four separate studies. 1. The foliage of two-week-old plants, growing in sulphur-free nutrient solution was treated with 1 X 10⁻² M KCHC solution and subsequently the roots were given a 4 hr exposure to 35[sub SO₄] in the nutrient solution. Slightly more sulphur-35 was taken up by treated plants than untreated control plants, but the difference was not statistically significant. However, significantly more sulphur-35 was detected in the leaves of treated plants. The differences in distribution were attributed to metabolic changes brought about by treatment. 2. Plants were handled as above and the leaves were harvested one, two, and five days after feeding sulphur-35. The leaf tissue was separated, chemically, into sulphate, lipid, free amino acid, perchloric acid soluble, and protein fractions. A portion of the protein fraction was hydrolyzed to permit separation of the sulphur-amino acids by chromatography. The bulk of the sulphur-35 was incorporated into the acid soluble fraction first and subsequently into the protein fraction. KCHC treated leaves contained significantly more acid soluble S initially and more protein S finally than control leaves. Control leaves contained more sulphate S than treated leaves two days after sulphur-35 feeding. These results indicated that KCHC treatment stimulated the incorporation of sulphur into protein, and this was consistent with other reports of increased protein formation due to naphthenate treatment. 3. Bush bean plants growing in complete nutrient solution were treated and exposed to calcium-45. Treated plants took up slightly less calcium than controls, and they retained significantly more of it in their roots. These results are in contrast to the effect of treatment on sulphur-35 uptake and distribution. Bush bean plants growing in complete nutrient solution were treated with KCHC solution at two weeks of age. One week later the distribution of sulphur, calcium, and magnesium was examined in leaf blades, stems plus petioles, and roots. No significant effect of treatment on uptake was found for any of the elements. Distribution of sulphur and calcium within the plant was not affected by treatment, but control plants contained significantly more magnesium in their leaves than treated plants. The lack of significant effect on ion uptake indicated that the increased growth found in many studies, when plants were treated with naphthenic acids, apparently was not the result of improved uptake of sulphur, calcium, or magnesium.

Challenges analyzing perchloroethylene in water samples

Publisher: name: F1000 Research Limited
Year: 2019

description: Objective: To explore the temperature and holding time constraints of water quality samples outlined in EPA Method 524.2.

Methods: Prepare 160 water samples representative of a municipal water source with a pH of 7.2 Spike with Perchloroethylene (PERC) to achieve a concentration of 5 ppm (v/v). Hold samples at four temperatures: 3℃, 5℃, 20℃, and 25℃ for 27 days. Samples were analyzed every three days for 27 days using Inficon’s HAPSITEⓇ ER. An additional analysis of 32 samples was conducted to identify proper mixing time for PERC in water. A regression model with a quadratic function was performed to determine statistically significant differences between concentration and time; concentration and time with temperature combined. A One Way Analysis of Variance (ANOVA) test was performed to identify statistically significant differences between concentration and temperature. A coefficient of variation was used to determine adequate mixing time.

Results: There is an indication of an effect in the concentration of PERC attributed to time and temperature. Ideal mixing time to achieve a 5ppm concentration under ambient conditions was identified to be within 1.5 to 2.5 hours.

Conclusion: Complexity of PERC’s solubility and volatility during analysis was not anticipated. Using a phosphate buffer solution creates a “salting out effect” where it disrupts the distribution of PERC in water. Physical properties, although incorporated as part of the challenges, became a crucial factor in the variation of PERC concentration.

description: Prompt tuning (PT) is a promising parameter-efficient method to utilize extremely large pre-trained language models (PLMs), which can achieve comparable performance to full-parameter fine-tuning by only tuning a few soft prompts. However, PT requires much more training time than fine-tuning. Intuitively, knowledge transfer can help to improve the efficiency. To explore whether we can improve PT via prompt transfer, we empirically investigate the transferability of soft prompts across different downstream tasks and PLMs in this work. We find that (1) in zero-shot setting, trained soft prompts can effectively transfer to similar tasks on the same PLM and also to other PLMs with a cross-model projector trained on similar tasks; (2) when used as initialization, trained soft prompts of similar tasks and projected prompts of other PLMs can significantly accelerate training and also improve the performance of PT. Moreover, to explore what decides prompt transferability, we investigate various transferability indicators and find that the overlapping rate of activated neurons strongly reflects the transferability, which suggests how the prompts stimulate PLMs is essential. Our findings show that prompt transfer is promising for improving PT, and further research shall focus more on prompts' stimulation to PLMs. The source code can be obtained from https://github.com/thunlp/Prompt-Transferability.

description: We have built a reliable and robust system that takes as input an astronomical image, and returns as output the pointing, scale, and orientation of that image (the astrometric calibration or WCS information). The system requires no first guess, and works with the information in the image pixels alone; that is, the problem is a generalization of the "lost in space" problem in which nothing--not even the image scale--is known. After robust source detection is performed in the input image, asterisms (sets of four or five stars) are geometrically hashed and compared to pre-indexed hashes to generate hypotheses about the astrometric calibration. A hypothesis is only accepted as true if it passes a Bayesian decision theory test against a background hypothesis. With indices built from the USNO-B Catalog and designed for uniformity of coverage and redundancy, the success rate is 99.9% for contemporary near-ultraviolet and visual imaging survey data, with no false positives. The failure rate is consistent with the incompleteness of the USNO-B Catalog; augmentation with indices built from the 2MASS Catalog brings the completeness to 100% with no false positives. We are using this system to generate consistent and standards-compliant meta-data for digital and digitized imaging from plate repositories, automated observatories, individual scientific investigators, and hobbyists. This is the first step in a program of making it possible to trust calibration meta-data for astronomical data of arbitrary provenance.

description: Mean-field treatment (MFT) is frequently applied to approximately predict the dynamics of quantum optics systems, to simplify the system Hamiltonian through neglecting certain modes that are driven strongly or couple weakly with other modes. While in practical quantum systems, the quantum correlations between different modes might lead to unanticipated quantum effects and lead to significantly distinct system dynamics. Here, we provide a general and systematic theoretical framework based on the perturbation theory in company with the MFT to capture these quantum effects. The form of nonlinear dissipation and parasitic Hamiltonian are predicted, which scales inversely with the nonlinear coupling rate. Furthermore, the indicator is also proposed as a measure of the accuracy of mean-field treatment. Our theory is applied to the example of quantum frequency conversion, in which mean-field treatment is commonly applied, to test its limitation under strong pump and large coupling strength. The analytical results show excellent agreement with the numerical simulations. Our work clearly reveals the attendant quantum effects under mean-field treatment and provides a more precise theoretical framework to describe quantum optics systems.

Incorporating mutual information into the algorithm leads to the selection procedure not only based on classification accuracy but also on efficiency. Effective image features are selected by using properly chosen Gabor wavelets optimised with Parallel AdaBoost method and mutual information to get high recognition rates with low computational cost.

description: Active particles may undergo phase separation when interactions oppose self-propulsion, in the absence of any cohesive forces. The corresponding Motility-Induced Phase Separation (MIPS) is arguably the simplest non-trivial collective feature that distinguishes active from passive particles. It is observed in a large variety of systems which we review in this chapter. We describe in depth the case of motile particles interacting via quorum-sensing interactions, whose theoretical framework is by now well-established. We close the chapter by discussing the features observed in systems undergoing MIPS that still challenge our understanding.

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

description: Principal component analysis (PCA) is a popular dimension reduction technique for vector data. Factored PCA (FPCA) is a probabilistic extension of PCA for matrix data, which can substantially reduce the number of parameters in PCA while yield satisfactory performance. However, FPCA is based on the Gaussian assumption and thereby susceptible to outliers. Although the multivariate $t$ distribution as a robust modeling tool for vector data has a very long history, its application to matrix data is very limited. The main reason is that the dimension of the vectorized matrix data is often very high and the higher the dimension, the lower the breakdown point that measures the robustness. To solve the robustness problem suffered by FPCA and make it applicable to matrix data, in this paper we propose a robust extension of FPCA (RFPCA), which is built upon a $t$-type distribution called matrix-variate $t$ distribution. Like the multivariate $t$ distribution, the matrix-variate $t$ distribution can adaptively down-weight outliers and yield robust estimates. We develop a fast EM-type algorithm for parameter estimation. Experiments on synthetic and real-world datasets reveal that RFPCA is compared favorably with several related methods and RFPCA is a simple but powerful tool for matrix-valued outlier detection.

The investigation of dispiro and fused ring tricyclic analogues of ethylenediamine type antihistaminics
Creators: name: Stephanson, Lawrence Gerald
Publisher: name: University of British Columbia
Year: 2011

description: The synthesis and pharmacological testing of two series of compounds for use in the investigation of the steric and electronic nature of the antihistaminic receptor is described. The dimethylaminoacetyl derivatives of 7-amino-14-azadispiro[5.1.5.2] -pentadecan-15-one and 8-amino-16-azadispiro[6.1.6.2] heptadecan-17-one and the methiodide salts of these compounds were synthesized. The di-methylaminoacetyl derivatives of the reduced ring systems, 7-amino-14-azadispiro[5 .1.5 .2] pentadecane and 8-amino-16-azadispiro [6 .1.6 .2] heptadecane, and the dimethiodide salts were also synthesized. Suitable compounds in this series were tested for local anesthetic activity by the guinea pig intradermal wheal method and for antihistaminic and antimus-carinic activity in isolated guinea pig ileum. Several of the compounds in this series were also screened for general activity and acute toxicity. The compounds in this series were inactive or showed only a very low order of activity. The 2-dimethylaminoethyl derivatives of carbazole, 1,2,3,4-tetra-hydrocarbazole, dodecahydrocarbazole, 1,2,3,4-tetrahydrocyclopent[b] -indole, dodecahydrocyclopent [b] indole, 5,6,7,8,9,10-hexahydrocyclohept-[b] indole, tetradecahydrocyclohept[b] indole, diphenylamine, dicyclohexyl-amine, fluorene, and 1,2,3,4,4a,9a-hexahydrofluorene were synthesized. The bis(2-dimethylaminoethyl) derivative of fluorene was also obtained. All of these compounds were tested for antihistaminic and antimus-carinic activity in isolated guinea pig ileum. The compounds showed only non-competitive antimuscarinic activity which was probably due to a non-specific toxic effect. All of the compounds showed competitive antihistaminic activity. The fully hydrogenated compounds and the di-substituted fluorene derivative showed non-competitive antihistaminic activity, again probably due to a non-specific toxic effect, as well as weak competitive antagonism. The seven aromatic or indolic compounds showed a high degree of competitive activity. These compounds, followed by the pA₂ values, were: 5-(2-dimethylaminoethyl)-5,6,7,8,9,10-hexahydrocyclohept[b] indole (7.94), 9-(2-dimethylaminoethyl)-1,2,3,4,4a,9a-hexahydrofluorene (7.45), 9-(2-dimethylaminoethyl)-1,2,3,4-tetrahydrocarbazole (6.90), N-(2-di-methylaminoethyl)diphenylamine (6.67), 9-(2-dimethylaminoethyl)carbazole (6.38), 9-(2-dimethylaminoethyl)fluorene (6.12), and 4-(2-dimethylamino-ethyl)-1,2,3,4-tetrahydrocyclopent[b] indole (6.12). The pA₂ value for diphenhydramine was found to be 7.75. The results are discussed in terms of the steric nature and possible binding modes of the antihistaminic receptor.

description: An important unresolved question in supersolid research is the degree to which the non-classical rotational inertia (NCRI) phenomenon observed in the torsional oscillator experiments of Kim and Chan, is evidence for a Bose-condensed supersolid state with superfluid-like properties. In an open annular geometry, Kim and Chan found that a fraction of the solid moment of inertia is decoupled from the motion of the oscillator; however, when the annulus is blocked by a partition, the decoupled supersolid fraction is locked to the oscillator being accelerated by an AC pressure gradient generated by the moving partition. These observations are in accord with superfluid hydrodynamics. We apply a low frequency AC pressure gradient in order to search for a superfluid-like response in a supersolid sample. Our results are consistent with zero supersolid flow in response to the imposed low frequency pressure gradient. A statistical analysis of our data sets a bound, at the 68% confidence level, of 9.6$\times 10^{-4}$ nm/s for the mass transport velocity carried by a possible supersolid flow. In terms of a simple model for the supersolid, an upper bound of 3.3$\times 10^{-6}$ is set for the supersolid fraction at 25 mK, at this same confidence level. These findings force the conclusion that the NCRI observed in the torsional oscillator experiments is not evidence for a frequency independent superfluid-like state. Supersolid behavior is a frequency-dependent phenomenon, clearly evident in the frequency range of the torsional oscillator experiments, but undetectably small at frequencies approaching zero.
