description: The goal of Unsupervised Reinforcement Learning (URL) is to find a reward-agnostic prior policy on a task domain, such that the sample-efficiency on supervised downstream tasks is improved. Although agents initialized with such a prior policy can achieve a significantly higher reward with fewer samples when finetuned on the downstream task, it is still an open question how an optimal pretrained prior policy can be achieved in practice. In this work, we present POLTER (Policy Trajectory Ensemble Regularization) - a general method to regularize the pretraining that can be applied to any URL algorithm and is especially useful on data- and knowledge-based URL algorithms. It utilizes an ensemble of policies that are discovered during pretraining and moves the policy of the URL algorithm closer to its optimal prior. Our method is based on a theoretical framework, and we analyze its practical effects on a white-box benchmark, allowing us to study POLTER with full control. In our main experiments, we evaluate POLTER on the Unsupervised Reinforcement Learning Benchmark (URLB), which consists of 12 tasks in 3 domains. We demonstrate the generality of our approach by improving the performance of a diverse set of data- and knowledge-based URL algorithms by 19% on average and up to 40% in the best case. Under a fair comparison with tuned baselines and tuned POLTER, we establish a new state-of-the-art for model-free methods on the URLB.

description: In the field of public health, treatment of multidrug-resistant (MDR) bacterial infection is a great challenge. Herein, we provide a solution to this problem with the use of graphene oxide-silver (GO-Ag) nanocomposites as antibacterial agent. Following established protocols, silver nanoparticles were grown on graphene oxide sheets. Then, a series of in vitro studies were conducted to validate the antibacterial efficiency of the GO-Ag nanocomposites against clinical MDR Escherichia coli (E. coli) strains. GO-Ag nanocomposites showed the highest antibacterial efficiency among tested antimicrobials (graphene oxide, silver nanoparticles, GO-Ag), and synergetic antibacterial effect was observed in GO-Ag nanocomposites treated group. Treatment with 14.0 µg ml−1 GO-Ag treatment could greatly inhibit bacteria growth; remaining bacteria viabilities were 4.4% and 4.1% for MDR-1 and MDR-2 E. coli bacteria, respectively. In addition, with assistance of photothermal effect, effective sterilization could be achieved using GO-Ag nanocomposites as low as 7.0 µg ml−1. Fluorescence imaging and morphology characterization uncovered that bacteria integrity was disrupted after GO-Ag nanocomposites treatment. Cytotoxicity results of GO-Ag using human-derived cell lines (HEK 293T, Hep G2) suggested more than 80% viability remained at 7.0 µg ml−1. All the results proved that GO-Ag nanocomposites are efficient antibacterial agent against multidrug-resistant E. coli.

description: In this paper we introduce four Z_2 topological indices zeta_k=0,1 at k=(0,0), (0,pi), (pi, 0), (pi, pi) characterizing 16 universal classes of 2D superconducting states that have translation symmetry but may break any other symmetries. The 16 classes of superconducting states are distinguished by their even/odd numbers of fermions on even-by-even, even-by-odd, odd-by-even, and odd-by-odd lattices. As a result, the 16 classes topological superconducting states exist even for interacting systems. For non-interacting systems, we find that zeta_k is the number of electrons on k=(0,0), (0,pi), (pi, 0), or (pi,pi) orbitals (mod 2) in the ground state. For 3D superconducting states with only translation symmetry, there are 256 different types of topological superconductors.

The emerging role of human resource management in industrial enterprises in China : past, current and future HR practices
Creators: name: Zhu, CJ
Publisher: name: University Of Tasmania
Year: 2023

description: In the late 1970s, the Chinese government announced an open-door policy and began economic reforms aimed at moving the country from a centrally planned economy to a market economy. This ongoing transition has resulted in significant changes in management practices in China's industrial sector and has profound implications for its human resource (HR) practices. Based on a review of the current literature, this thesis examines the rise of a highly centralised command economy and dominance of public ownership during Mao's regime and changes that occurred in both the economic system and ownership structure since economic reform. It also discusses the impact of different economic systems and ownership forms on management and HR practices in China's industrial enterprises. There is a dearth of research that systematically examines current HR practices in Chinese industrial enterprises, especially across enterprises with different types of ownership. Given this, the thesis identifies three research questions: 1) How were human resources in Chinese industrial enterprise managed before and after the commencement of economic reform with respect to major HR activities, including: human resource planning; recruitment and selection; performance appraisal; compensation and welfare; training and development; and labour relations? 2) What impact does form of ownership have on HR practices in Chinese industrial enterprises? 3) What are the possible future development paths of human resource management (HRM) in Chinese industrial enterprises? The three research questions were investigated and addressed through four major case studies conducted in four enterprises with different ownership forms in China and survey questionnaires with 440 respondents. Each case study and survey result was discussed and analysed separately. This was followed by a comparative analysis between the qualitative (case studies) and quantitative (survey) studies. The thesis thus achieved its primary purpose, namely, to explore the emerging role of HRM in China's industrial enterprises with different types of ownership. It enhances the understanding of HRM in the Chinese industrial sector by offering empirical evidence of past and current practices across the major HR activities, and pointing to future HR trends within the sector. It also contributes to the theory of HRM by exploring HR practices across enterprises with four types of ownership to investigate the impact of ownership form on HRM. In addition, the study proposes a model of HRM that indicates possible future development paths for HRM in Chinese industrial enterprises and discusses future HRM challenges, emphasising the significance of training the workforce in China for such challenges. Research limitations and recommendations for future research are identified and presented.

description: Additional file 5. Fig. S4. Classification of cellular barcodes in the PDX dataset. The sequenced reads of the P3 sample in the public PDX dataset were classified and grouped by the cellular barcodes they are associated with. Then, cellular barcodes are plotted based on the number of graft- and host-specific reads they contain. A cellular barcode was labelled “graft” if at least 90% of its reads are graft-specific, and “host” if at least 90% of reads are host-specific. While most cellular barcodes clearly originate from graft cells, we identified several cellular barcodes with a high number of host-specific reads, therefore likely originating from host cells that contaminated the sample. While the precise number of contaminating host cells depends on the cell identification threshold, there are 11 cellular barcodes with more than 250,000 host-specific reads and less than 5% graft-specific reads, which would likely pass most cell filtering procedures and be included in the analysis. Without prior XenoCell filtering, 19 host cells were included in the final dataset when we processed it with STARsolo (default parameters).

description: Long-term observations of photoluminescence at the single-molecule level were until recently very diffcult, due to the photobleaching of organic ?uorophore molecules. Although inorganic semiconductor nanocrystals can overcome this diffculty showing very low photobleaching yield, they suffer from photoblinking. A new marker has been recently introduced, relying on diamond nanoparticles containing photoluminescent color centers. In this work we compare the photoluminescence of single quantum dots (QDs) to the one of nanodiamonds containing a single-color center. Contrary to other markers, photoluminescent nanodiamonds present a perfect photostability and no photoblinking. At saturation of their excitation, nanodiamonds photoluminescence intensity is only three times smaller than the one of QDs. Moreover, the bright and stable photoluminescence of nanodiamonds allows wide field observations of single nanoparticles motion. We demonstrate the possibility of recording the tra jectory of such single particle in culture cells.

description: Data valuation has wide use cases in machine learning, including improving data quality and creating economic incentives for data sharing. This paper studies the robustness of data valuation to noisy model performance scores. Particularly, we find that the inherent randomness of the widely used stochastic gradient descent can cause existing data value notions (e.g., the Shapley value and the Leave-one-out error) to produce inconsistent data value rankings across different runs. To address this challenge, we introduce the concept of safety margin, which measures the robustness of a data value notion. We show that the Banzhaf value, a famous value notion that originated from cooperative game theory literature, achieves the largest safety margin among all semivalues (a class of value notions that satisfy crucial properties entailed by ML applications and include the famous Shapley value and Leave-one-out error). We propose an algorithm to efficiently estimate the Banzhaf value based on the Maximum Sample Reuse (MSR) principle. Our evaluation demonstrates that the Banzhaf value outperforms the existing semivalue-based data value notions on several ML tasks such as learning with weighted samples and noisy label detection. Overall, our study suggests that when the underlying ML algorithm is stochastic, the Banzhaf value is a promising alternative to the other semivalue-based data value schemes given its computational advantage and ability to robustly differentiate data quality.

Digital photogrammetric mapping of canopy height in a radiata pine plantation
Creators: name: Wijanarto, AB
Publisher: name: University Of Tasmania
Year: 2023

description: Tree height is a crucial stand characteristic in forest inventories and has been used widely to estimate timber volume, to monitor growth rate, and as an indicator of site quality. Current tree heighting relies on field measurements, with sampling rates, which are typically less than one percent. Low sampling rates produce high variation in measured parameters and reduce statistical reliability. Digital photogrammetry provides an opportunity to automate the measurement of tree heights and to generate digital models of forest canopies. A sufficiently dense canopy model, with tree height data at nearly 100% sampling rates, has the potential to improve significantly the reliability of strategic and operational forest inventory. This study investigates the utility of digital photogrammetric techniques to map tree height within radiata pine plantations. A digital photogrammetric workstation, the Leica Helava DPW 770, was used to generate digital canopy models of both closed canopy and thinned stands. The performance of the image-matching algorithm was assessed using scanned aerial photos of different film types and scales, including colour, black and white, colour infrared, and black and white infrared, at 1:5,000, 1:10,000, and 1:15,090 scales. Canopy height data were obtained by subtracting a DTM from the photogrammetric data. Various filtering strategies were used to process the canopy height data including median, mean tallest tree, adaptive wavelet, adaptive Fourier filtering, and NDVI-thresholding techniques. A method for improving automatically derived tree height using a limited number of manually measured tree heights using a DPW was also developed. The reliability of the derived data was assessed by comparing it with a reference DCM produced using an analytical stereoplotter at a lOm grid, and field measurements. The study demonstrates that tree heights in a coniferous forest can be mapped using digital photogrammetric methods and appropriate post-processing. Filtered digital photogrammetric data are shown comparable to analytical stereoplotter data and field-measured data, particularly for dense stand. With the efficiency and high sampling rates afforded by digital photogrammetric techniques, this study demonstrates the potential application of photogrammetrically measured tree height data to forest inventory.

Inclusive and exclusive longitudinal momentum distributions and cross-sections were measured enabling the determination of the orbital angular momentum of the populated states. First-time observation of the 955(6) keV nu p3/2-hole state in 55Ti is reported. The measured data for the first time proves that the ground state of 55Ti is a 1/2- state, in agreement with shell-model calculations using the GXPF1A interaction that predict a sizable N=34 gap in 54Ca.

Video-tape in interviewing : an analysis of ratings and attitudes
Creators: name: Lee, Alec John
Publisher: name: University of British Columbia
Year: 2011

description: This study was intended to examine three aspects of interviewing. The first was an exploration for any systematic differences between ratings given by interviewers in actual face-to-face interviews and ratings given by group (N=3) and individual observers of video-taped interviews. The second aspect was a comparison between group (N=3) and individual ratings in terms of mean variable ratings, reliability and halo error. The third section sought attitudes of interviewees and rating viewers of the utility of videotape in employment interviews. The interviewees for the first and third aspects of this study were thirty-four fourth-year Commerce students from the University of British Columbia. The video-tape viewers and interviewers were thirty members of the Bank of Montreal's managerial staff. For the second section the interviewees were three fourth-year Commerce students from the University of British Columbia and the video-tape viewers were one hundred and eighty-five Commerce undergraduate students also from the University of British Columbia. The viewers and interviewers were requested to evaluate interviewees along thirteen dimensions and to decide whether or not to call back the interviewees for further interviews. Minimal differences were found between interviewer and group observer ratings while individual observer ratings were found to be uniformly and significantly higher than both interviewer and group observer ratings. Reliability estimates were generally moderate to low with no significant differences existing between group and individual ratings. Halo error was possibly a contributing factor for group and individual ratings. The attitudes of interviewees toward the use of video-tape in interviewing were quite favorable. The viewers, on the other hand, displayed only a moderate enthusiasm. In the discussion, attention was given to methods for revising the Bank of Montreal's interview ratings form and interviewing procedure.

description: This research seeks to use reliability technique to improve operational output through cost reduction of the main engine system of a ship. The various subsystems of the marine vessel main engine were identified. The failure mode effect and criticality index of the engine system and their root causes were analyzed. The reliability of the main engine system was analyzed using exponential reliability model and a maintenance task that reduces the operational cost of main engine system was generated thereby improving output. The reliability centred maintenance technique identified all the perspectives of failures in the ship main engine systems and employed the appropriate maintenance approach for each failure respectively. The results of the reliability analysis performed on the main engine systems generated the proposed preventive maintenance (PM) tasks and plan. Decrease in the rate of Run-ToFailure (RTF) data remains inevitable and programmed performance of condition based, task demand and fault finding (CD, TD and FF) was recommended. The projected work program if implemented will decrease labour cost from N177, 600,000.00/year to N100, 800,000.00/year (approximately 43.24% of the total annual labour expenditure). The projected PM scheduling outcomes showed a 44.64% saving in the total cost of maintenance when compared with the existing RTF practice. The main engine systems reliability increases with decreased labour cost. The proposed spare parts plan for the main engine systems was generated and the results showed that approximately 55.42% of the yearly costs of spare parts are saved when projected PM scheduling is adopted.

description: We present a spectroscopic sample of 910 distant halo stars from the Hypervelocity Star survey from which we derive the velocity dispersion profile of the Milky Way halo. The sample is a mix of 74% evolved horizontal branch stars and 26% blue stragglers. We estimate distances to the stars using observed colors, metallicities, and stellar evolution tracks. Our sample contains twice as many objects with R>50 kpc as previous surveys. We compute the velocity dispersion profile in two ways: with a parametric method based on a Milky Way potential model, and with a non-parametric method based on the caustic technique originally developed to measure galaxy cluster mass profiles. The resulting velocity dispersion profiles are remarkably consistent with those found by two independent surveys based on other stellar populations: the Milky Way halo exhibits a mean decline in radial velocity dispersion of -0.38+-0.12 km/s/kpc over 15

description: Accurate camera pose estimation is a fundamental requirement for numerous applications, such as autonomous driving, mobile robotics, and augmented reality. In this work, we address the problem of estimating the global 6 DoF camera pose from a single RGB image in a given environment. Previous works consider every part of the image valuable for localization. However, many image regions such as the sky, occlusions, and repetitive non-distinguishable patterns cannot be utilized for localization. In addition to adding unnecessary computation efforts, extracting and matching features from such regions produce many wrong matches which in turn degrades the localization accuracy and efficiency. Our work addresses this particular issue and shows by exploiting an interesting concept of sparse 3D models that we can exploit discriminatory environment parts and avoid useless image regions for the sake of a single image localization. Interestingly, through avoiding selecting keypoints from non-reliable image regions such as trees, bushes, cars, pedestrians, and occlusions, our work acts naturally as an outlier filter. This makes our system highly efficient in that minimal set of correspondences is needed and highly accurate as the number of outliers is low. Our work exceeds state-ofthe-art methods on outdoor Cambridge Landmarks dataset. With only relying on single image at inference, it outweighs in terms of accuracy methods that exploit pose priors and/or reference 3D models while being much faster. By choosing as little as 100 correspondences, it surpasses similar methods that localize from thousands of correspondences, while being more efficient. In particular, it achieves, compared to these methods, an improvement of localization by 33% on OldHospital scene. Furthermore, It outstands direct pose regressors even those that learn from sequence of images

description: We consider the interaction of two perfectly conducting plates of arbitrary shape that are inside a non-simply connected cylinder with transverse section of the same shape. We show that the existence of transverse electromagnetic (TEM) modes produces a Casimir force that decays only as $1/a^2$, where $a$ is the distance between plates. The TEM force does not depend on the area of the plates and dominates at large distances over the force produced by the transverse electric (TE) and transverse magnetic (TM) modes, providing in this way a physical realization of the 1+1 dimensional Casimir effect. For the particular case of a coaxial circular cylindrical cavity, we compute the TE, TM and TEM contributions to the force, and find the critical distance for which the TEM modes dominate.

description: HyperDimensional Computing (HDC) as a machine learning paradigm is highly interesting for applications involving continuous, semi-supervised learning for long-term monitoring. However, its accuracy is not yet on par with other Machine Learning (ML) approaches. Frameworks enabling fast design space exploration to find practical algorithms are necessary to make HD computing competitive with other ML techniques. To this end, we introduce HDTorch, an open-source, PyTorch-based HDC library with CUDA extensions for hypervector operations. We demonstrate HDTorch's utility by analyzing four HDC benchmark datasets in terms of accuracy, runtime, and memory consumption, utilizing both classical and online HD training methodologies. We demonstrate average (training)/inference speedups of (111x/68x)/87x for classical/online HD, respectively. Moreover, we analyze the effects of varying hyperparameters on runtime and accuracy. Finally, we demonstrate how HDTorch enables exploration of HDC strategies applied to large, real-world datasets. We perform the first-ever HD training and inference analysis of the entirety of the CHB-MIT EEG epilepsy database. Results show that the typical approach of training on a subset of the data does not necessarily generalize to the entire dataset, an important factor when developing future HD models for medical wearable devices.

Architektur, Bewegung, Gewaltsamkeit. Poelzig, Mendelsohn – und Montage
Creators: name: Dauss, Markus
Publisher: name: Universität Regensburg
Year: 2021
Subjects: subject: 700 Künste, Bildende Kunst allgemein

description: Der Beitrag befasst sich damit, wie Bewegung in gebaute Strukturen übersetzt wird. Die Darstellung setzt an Hans Poelzigs I.G.-Farben-Verwaltungsgebäude in Frankfurt am Main an und schält zunächst markante Mobilitätsmotive des Gebäudes sowie deren Gegenspieler heraus. Anschließend behandelt sie theoretische wie morphologische Bezüge der Architektur zum Leitmedium der dynamischen Moderne – zum Film. Die intermediale Verzahnung beider Künste wird dabei nicht nur anhand von Poelzig selbst rekonstruiert, sondern auch von Werken und Gedanken des Zeitgenossen Erich Mendelsohn. Über die Scharnierkategorie der Montage wird dann die Verbindung zu filmischer und architektonischer Bewegung hergestellt – und gezeigt, inwiefern in diese Gewaltsamkeit kulturell encodiert ist.

description: We prove a deletion-contraction formula for motivic Feynman rules given by the classes of the affine graph hypersurface complement in the Grothendieck ring of varieties. We derive explicit recursions and generating series for these motivic Feynman rules under the operation of multiplying edges in a graph and we compare it with similar formulae for the Tutte polynomial of graphs, both being specializations of the same universal recursive relation. We obtain similar recursions for graphs that are chains of polygons and for graphs obtained by replacing an edge by a chain of triangles. We show that the deletion-contraction relation can be lifted to the level of the category of mixed motives in the form of a distinguished triangle, similarly to what happens in categorifications of graph invariants.

description: Advanced LIGO and Advanced Virgo ground-based interferometers are instruments capable to detect gravitational wave signals exploiting advanced laser interferometry techniques. The underlying data analysis task consists in identifying specific patterns in noisy timeseries, but it is made extremely complex by the incredibly small amplitude of the target signals. In this scenario, the development of effective gravitational wave detection algorithms is crucial. We propose a novel layered framework for real-time detection of gravitational waves inspired by speech processing techniques and, in the present implementation, based on a state-of-the-art machine learning approach involving a hybridization of genetic programming and neural networks. The key aspects of the newly proposed framework are: the well structured, layered approach, and the low computational complexity. The paper describes the basic concepts of the framework and the derivation of the first three layers. Even if the layers are based on models derived using a machine learning approach, the proposed layered structure has a universal nature. Compared to more complex approaches, such as convolutional neural networks, which comprise a parameter set of several tens of MB and were tested exclusively for fixed length data samples, our framework has lower accuracy (e.g., it identifies 45% of low signal-to-noise-ration gravitational wave signals, against 65% of the state-of-the-art, at a false alarm probability of $10^{-2}$), but has a much lower computational complexity and a higher degree of modularity. Furthermore, the exploitation of short-term features makes the results of the new framework virtually independent against time-position of gravitational wave signals, simplifying its future exploitation in real-time multi-layer pipelines for gravitational-wave detection with new generation interferometers.
Origin of Drastic Change of Fermi Surface and Transport Anomalies in CeRhIn5 under Pressure

description: The mechanism of drastic change of Fermi surfaces as well as transport anomalies near P=Pc=2.35 GPa in CeRhIn5 is explained theoretically. The key mechanism is pointed out to be the interplay of magnetic order and Ce-valence fluctuations. We show that the antiferromagnetic state with "small" Fermi surfaces changes to the paramagnetic state with "large" Fermi surfaces with huge enhancement of effective mass of electrons with keeping finite c-f hybridization. This explains the drastic change of the de Haas-van Alphen signals. Furthermore, it is also consistent with the emergence of T-linear resistivity simultaneous with the residual resistivity peak at P=Pc in CeRhIn5.

Phase structure of electroweak vacuum in a strong magnetic field: the lattice results

description: Using first-principle lattice simulations, we demonstrate that in the background of a strong magnetic field (around $10^{20}$ T), the electroweak sector of the vacuum experiences two consecutive crossover transitions associated with dramatic changes in the zero-temperature dynamics of the vector $W$ bosons and the scalar Higgs particles, respectively. Above the first crossover, we observe the appearance of large, inhomogeneous structures consistent with a classical picture of the formation of $W$ and $Z$ condensates pierced by vortices. The presence of the $W$ and $Z$ condensates supports the emergence of the exotic superconducting and superfluid properties induced by a strong magnetic field in the vacuum. We find evidence that the vortices form a disordered solid or a liquid rather than a crystal. The second transition restores the electroweak symmetry. Such conditions can be realized in the near-horizon region of the magnetized black holes.
