description: A generalised definition of the metric of quantum states is proposed by using the techniques of differential geometry. The metric of quantum state space derived earlier by Anandan, is reproduced and verified here by this generalised definition. The metric of quantum states in the configuration space and its possible geometrical framework is explored. Also, invariance of the metric of quantum states under local gauge transformations, coordinate transformations, and the relativistic transformations is discussed.

description: In order to evaluate the risk level of water inrush caused by karst cave accurately and effectively, a novel quantitative assessment model was established based on the reliability theory and genetic algorithm-back propagation (GA-BP) neural network. First, the reliability theory and the calculation formula of the minimum safe thickness were used to calculate the water inrush probability. Second, the GA-BP neural network was applied to predict the disaster consequence caused by water inrush. Six factors, including water pressure, hydraulic supply, type of gap, filling situation, degree of water enrichment and reserves of cave, were selected as the input layer of the neural network. The disaster consequence was selected as the output layer. Similar projects were screened to obtain statistical information for indices, and the Normand function in MATLAB was used to transform the information into quantitative data. Finally, the model was established by combining the probability and disaster consequence of water inrush. The 602cave in Yesanguan tunnel was taken as an engineering sample to verify the feasibility of the novel model. The obtained results showed that the proposed model is comprehensive and accurate in quantitative assessment, which has good application prospects in engineering.

description: We present a new class of dualities relating non-geometric Calabi-Yau compactifications of type II string theory to T-fold compactifications of the heterotic string, both preserving four-dimensional $\mathcal{N}=2$ supersymmetry. The non-geometric Calabi-Yau space is a $K3$ fibration over $T^2$ with non-geometric monodromies in the duality group $O(Γ_{4,20})$; this is dual to a heterotic reduction on a $T^4$ fibration over $T^2$ with the $O(Γ_{4,20})$ monodromies now viewed as heterotic T-dualities. At a point in moduli space which is a minimum of the scalar potential, the type II compactification becomes an asymmetric Gepner model and the monodromies become automorphisms involving mirror symmetries, while the heterotic dual is an asymmetric toroidal orbifold. We generalise previous constructions to ones in which the automorphisms are not of prime order. The type II construction is perturbatively consistent, but the naive heterotic dual is not modular invariant. Modular invariance on the heterotic side is achieved by including twists in the circles dual to the winding numbers round the $T^2$, and this in turn introduces non-perturbative phases depending on NS5-brane charge in the type II construction.

description: Karyotypes in 12 taxa of Euphorbia were studied karyomorphologically. The karyotypes of Euphorbia cheiradenia, E. pannonica, E. pestalozzae, E. petrophila, E. pisidica, E. thessala and E. yildirimli are described for the first time. Karyological analyses indicate relationships among the species with respect to their asymmetry indices. Most of the investigated taxa are diploid with 2n = 2x = 18 chromosomes. E. macroclada and E. smirnovii showed tetraploid cytotypes 2n = 4x = 36. All karyotypes are symmetrical, consisting of metacentric and submetacentric chromosomes. The chromosomes range in size from 0.79 µm to 2.20 µm. The total haploid chromosome length (THL) varies from 8.75 μm (E. terracina) to 16.78 μm (E. petrophila). PCoA (Principal Coordinate Analysis) with five uncorrelated parameters was performed to determine the karyological relationships among the taxa.

Resource Delivery and Teaching in Live Chat Reference: Comparing Two Libraries

Publisher: name: University of Illinois at Chicago
Year: 2022
Subjects: subject: Library and Information Studies
subject: FOS: Media and communications

description: This study investigates how reference staff at two libraries balance teaching with resource delivery in live chat reference. Analysis of 410 transcripts from one week shows that one library tends to deliver more resources from a wider range of database suggestions, to take more time in chat interactions, and to incorporate more teaching behavior with specific resource links. Two possible reasons for these differences are reference policies and staffing models: one library states that chat is for brief factual questions and monitors chat from a public service point; the other does not state a policy and monitors chat from private offices. Findings are important for staffing responsively, developing effective research guides, and improving teaching in online reference.

description: Sea salinity is one of the indicators of the global water cycle and affects the surface and deep circulation of the ocean. While passive microwave satellite sensors have been used to monitor sea surface salinity (SSS), the uncertainties from radio frequency interference (RFI) and low sea surface temperature often result in large errors, especially in river-dominated coastal seas. This study investigated the improvement of the Soil Moisture Active Passive (SMAP) SSS over five river-dominated oceans over the globe using three machine learning approaches (i.e., random forest (RF), support vector regression (SVR), and artificial neural network (ANN)). Four SMAP products and four ancillary data used in the SMAP SSS retrieval algorithm were used as input variables to the machine learning models. The results showed that all models improved the SMAP SSS product by up to 28% reduced in the root mean square error (RMSE) for validation, and RF yielded better performance than SVR and ANN. The calibration and validation RMSEs by RF were 0.203 and 0.556 practical salinity unit (psu), while those of SMAP SSS were 0.774 psu. The improved SSS well captured the spatiotemporal patterns of SSS for not only low but also high salinity water for all five regions. The proposed approach can be used to operationally improve the global SMAP SSS product including other coastal areas and the near Polar regions in the future.

description: Hardware synthesis is a general term used to refer to the processes involved in automatically generating a hardware design from its specification. High-level synthesis (HLS) could be defined as the translation from a behavioral description of the intended hardware circuit into a structural description similar to the compilation of programming languages (such as C and Pascal into assembly language. The chained synthesis tasks at each level of the design process include system synthesis, register-transfer synthesis, logic synthesis, and circuit synthesis. The development of hardware solutions for complex applications is no more a complicated task with the emergence of various HLS tools. Many areas of application have benefited from the modern advances in hardware design, such as automotive and aerospace industries, computer graphics, signal and image processing, security, complex simulations like molecular modeling, and DND matching. The field of HLS is continuing its rapid growth to facilitate the creation of hardware and to blur more and more the border separating the processes of designing hardware and software.

description: We relate two apparently different bases in the representations of affine Lie algebras of type A: one arising from statistical mechanics, the other from gauge theory. We show that the two are governed by the same combinatorics and therefore can be viewed as identical. In particular, we are able to give an alternative and much simpler geometric proof of a result of E. Date, M. Jimbo, A. Kuniba, T. Miwa and M. Okado on the construction of bases of affine Lie algebra representations. At the same time, we give a simple parametrization of the irreducible components of Nakajima quiver varieties associated to infinite and cyclic quivers. We also define new varieties whose irreducible components are in one-to-one correspondence with bases of the highest weight representations of affine gl_{n+1}.

description: Retrotransposon are an abundant and ancient parts of the plant genomes that especially LTR retrotransposons influence the genome size and evolution. Sukkula is a non-autonomous and active, relatively high copy-number retroelement. In this study, we performed fluorescence in situ hybridization (FISH) to observe the distributions of Sukkula elements (LTRs and internal-domain) by using labelled-PCR products. The localizations of Sukkula elements (LTRs and internal-domain) were observed under confocal microscope on Hordeum vulgare L. cv. Hasat root preparations. Our results revealed that Sukkula elements is still active and spread through the whole barley chromosomes. Additionally, the re-sequencing analysis of Sukkula LTRs demonstrated that LTRs sequences had ~65 bp gain. These analyses represent a valuable resource to reveal genome organization of barley and large sized plants.

description: This article attempts to look into some of the links between modernity and tradition, the link to place and globalisation, using several "protected origin products" as the basis of the investigation. It is argued that the concept of protecting products, despite its ancient tradition, is a thoroughly modern occurrence with its emphasis on the local and the collective. Can consumption theory help provide part of the explanation for the (re)emergence of regional speciality foods in the UK ? The research naturally crosses boundaries between traditional disciplines and this work draws on a wide range of literature, especially that of post-modern theories of consumption. Consumption has become a major focus of research in the social sciences and humanities. It is increasingly perceived as central to understanding the historical development of modern industrial society and the social and cultural structure of postmodern societies. Focus on the supply chain brings to the debate a more holistic approach. Secondary information about the products under investigation, interviews with those in the supply chain and results from focus groups will be used to investigate the identified tensions. A final section will involve a discussion of PDO/PGI in its historical and current context in the UK, with a brief introduction to intellectual property Jaw which questions the importance of Regulation 2081/92 in the UK, in comparison to many southern European countries. The authors believe that, although abstract, a link can be conceived between theory and practice, and that UK consumers, along with many producers, intermediaries, retailers and institutions, may understand the protection at a deeper level than previously thought. The Regulation was met with much scepticism, and many remain ambivalent, but it is shown that those in the supply chain have positive hopes for the future.

description: Background and aim: A non-inferiority cost analysis was performed to assess if the early capsule approach would incur higher costs than the standard of care approach in patients presenting with non-hematemesis gastrointestinal bleeding. Methods: A prospective non-inferiority cost analysis was performed on patients receiving either an early video capsule as the first diagnostic procedure or an endoscopic procedure as determined by gastroenterology staff that were not involved in the study. Primary outcome was total direct costs incurred in both groups. Results: Forty-five patients and 42 patients were enrolled into the early capsule and standard of care arms, respectively. There was no difference in total direct cost per inpatient case in both groups ($7,362 vs $7,148, p = 0.77 [CI = −2,285–2,315, equivalent margin = –$3,100]). Localization of a bleeding source after the first diagnostic procedure was identified more frequently in the early capsule group (69.2% vs 27.9%, p = 0.0003). If patients were discharged after their last non-diagnostic evaluation, then length of stay could be decreased by 50% in both groups (58.5 to 31.6 h, p = 0.02 in the early capsule group and 69.4 to 39.2 h in the standard of care group p = 0.001). Projections indicate the fastest a patient with non-diagnostic evaluations could be discharged is 0.88 days in the early capsule group vs 1.63 days in the standard of care group (p = 0.0005). Discussion: In patients with non-hematemesis bleeding, video capsule endoscopy may be a more efficient diagnostic approach than the standard of care approach, since it detects bleeding significantly more often without an increase in healthcare costs.

description: The notion of spontaneous symmetry breaking has been used to describe phase transitions in a variety of physical systems. In crystalline solids, the breaking of certain symmetries, such as mirror symmetry, is difficult to detect unambiguously. Using 1$T$-TaS$_2$, we demonstrate here that rotational-anisotropy second harmonic generation (RA-SHG) is not only a sensitive technique for the detection of broken mirror symmetry, but also that it can differentiate between mirror symmetry-broken structures of opposite planar chirality. We also show that our analysis is applicable to a wide class of different materials with mirror symmetry-breaking transitions. Lastly, we find evidence for bulk mirror symmetry-breaking in the incommensurate charge density wave phase of 1$T$-TaS$_2$. Our results pave the way for RA-SHG to probe candidate materials where broken mirror symmetry may play a pivotal role.

description: It is shown that the operator sum representation for non-Markovian dynamics and the Lindblad master equation in Markovian limit can be derived from a formal solution to quantum Liouville equation for a qubit system in the presence of decoherence processes self-consistently. Our formulation is the first principle theory based on projection-operator formalism to obtain an exact reduced density operator in time-convolutionless form starting from the quantum Liouville equation for a noisy quantum computer. The advantage of our approach is that it is general enough to describe a realistic quantum computer in the presence of decoherence provided details of the Hamiltonians are known.

description: Objective: Recent studies have provided new insights into the role of lymph nodes (LNs) in rheumatoid arthritis (RA). The aim of this study was to evaluate the metabolic activity of the axillary LNs in relation to that of the upper limb joints and the clinical assessment of disease activity in RA patients treated with biologic therapies. Method: 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) scans were acquired for 64 patients with RA at baseline and after 6 months of biologic therapy, and the patients’ clinical status was evaluated. The maximum standardized uptake value (SUVmax), metabolic active volume, and total lesion glycolysis (TLG) were used to assess glucose metabolism in the LNs and 12 joints. Clinical evaluations included serum markers and the Disease Activity Score based on 28-joint count–erythrocyte sedimentation rate (DAS28-ESR). Results: Changes in the SUVmax and TLG for the axillary LNs correlated significantly with those of the ipsilateral wrist joints. There was a positive correlation between the changes in the three metabolic parameters of the axillary LNs and the changes in disease activity after treatment. After 6 months of biologic therapy, all metabolic parameters for the axillary LNs in patients with a DAS28-ESR Conclusion: A relationship between the glucose metabolism of the axillary LNs and the ipsilateral wrist joints was demonstrated by the 18F-FDG-PET/CT parameters. The metabolic activity and active volume of axillary LNs may reflect the therapeutic response to the biologic treatment of RA.

description: Co-operation and co-ordination along the supply chain are important factors influencing the performance of products. There is a considerable body of literature which suggests that modern business practices, concentrating on the final consumer, bring benefits to the market-orientated producers. The article attempts to discover the ability of participants to adapt to changing market signals in the supply chain and to identify their strategic objectives. To examine the influences of co-operation and co-ordination two cases will be examined. Semi-structured in-depth interviews were conducted with representatives from the actors within the supply chains and the surrounding social, economic and political system. Both the Jersey Royal (from the UK) and the Opperdoezer Ronde (from the Netherlands) are early potatoes, with limited production and a small market share. They are both PDO products, which could allow for noncommoditised relations between the members of the supply chain. However, the similarities end there. The marketing of the Jersey Royal is highly organised in terms of supply chain co-operation, whereas the Opperdoezer Ronde producers have little co-operation or co-ordination. The case studies examine the influence of the differences in co-operation and co-ordination on the product performance of both products.

description: An islanded microgrid supplied by multiple distributed energy resources (DERs) often employs droop-control mechanisms for power sharing. Because microgrids do not include inertial elements, and low pass filtering of noisy measurements introduces lags in control, droop-like controllers may pose significant stability concerns. This paper aims to understand the effects of droop-control on the small-signal stability and transient response of the microgrid. Towards this goal, we present a compendium of results on the small-signal stability of droop-controlled inverter-based microgrids with heterogeneous loads, which distinguishes: (1) lossless vs. lossy networks; (2) droop mechanisms with and without filters, and (3) mesh vs. radial network topologies. Small-signal and transient characteristics are also studied using multiple simulation studies on IEEE test systems

description: Kanamycin (KANA) plays a key role in the treatment of bacterial infections and has been widely used in animal husbandry. However, its overuse causes antibiotic residues in animal-derived foods. Determination methods for KANA are urgently needed for food safety. Most of the developed fluorescent aptamer sensors for detecting KANA use parental aptamer (kana-Apt) as recognition unit. However, excessive bases tend to form secondary structures and lead to high background or nonspecific signals. In this study, two fluorescent sensors based on one (kana1-Apt) and two (kana1/kana2-Apt) split fragments were developed for KANA detection. The LODs of the kana1-Apt/ThT system and kana1/kana2-Apt/ThT systems were 4.88 nM and 4.53 nM, respectively. In addition, satisfactory recoveries of the kana1-Apt/ThT system and kana1/kana2-Apt/ThT system were obtained in the detection of KANA in milk, which were 97.6%-104.5% and 98.4%-105.9%, respectively. Moreover, the results indicated that the kana1-Apt fragment plays a critical role in recognition. In conclusion, the results of the present study provide a novel strategy for molecular detection based on split aptamers.

description: We examine a family of BPS solutions of ten-dimensional type IIb supergravity. These solutions asymptotically approach AdS_5 X S^5 and carry internal `angular' momentum on the five-sphere. While a naked singularity appears at the center of the anti-de Sitter space, we show that it has a natural physical interpretation in terms of a collection of giant gravitons. We calculate the distribution of giant gravitons from the dipole field induced in the Ramond-Ramond five-form, and show that these sources account for the entire internal momentum carried by the BPS solutions.

description: In this study, the toxic effects of benzyl benzoate, which is widely used in the food, cosmetics, agriculture and pharmaceutical sectors, have been investigated using Allium cepa L. test material. In the determination of toxicity, physiological parameters with determination of root lengths, weight gains and germination percentages; cytogenetic changes with determination of chromosomal abnormalities formation, micronucleus (MN) frequency and mitotic index ratio (MI); anatomical changes with determination of anatomical differentiations in root tip cells; biochemical changes with lipid peroxidation and antioxidant enzyme analysis were determined and the obtained data were evaluated statistically. The bulbs were divided into four groups consisting of one control and three application groups, bulbs of the control group were treated with tap water and the bulbs of the application groups were treated with Benzyl benzoate at doses of 10,000, 25,000 and 50,000 mg/L for 72 hours. At the end of the study, it was determined that germination percentage, weight gain and root length and MI ratio decreased, chromosomal abnormalities, MN formation, MDA, SOD and CAT levels increased dose-dependent in the application groups when compared with the control group. Depending on the application, it has been determined that root cells have chromosomal abnormalities such as fragments, sticky chromosomes, chromosome bridges, unequal distribution of chromatins and c-mitosis. Furthermore, when compared with the control group, it was determined that benzyl benzoate administration caused anatomical changes in root tip cells. It was determined that these changes were in the form of necrosis, cell deformation, flattened cell nuclei, cortex cell deformation, accumulation of certain substances in cortex cells, wall thickening in cortex cells and unclear vascular tissue. In conclusion, it was determined by physiological, anatomical, cytogenetic and biochemical parameters that benzyl benzoate showed a dose-dependent toxic effect in Allium cepa L. root cells. Also, the parameters used in the study were determined to be useful biomarkers for the determination of toxicity.

description: BACKGROUND AND AIM: We performed a non-inferiority cost analysis to assess if the early capsule approach would incur higher costs than the standard of care approach in patients presenting with non-hematemesis gastrointestinal bleeding. METHODS: A prospective non-inferiority cost analysis was performed on patients receiving either an early video capsule as the first diagnostic procedure or an endoscopic procedure as determined by gastroenterology staff that were not involved in the study. Primary outcome was total direct costs incurred in both groups. RESULTS: 45 patients and 42 patients were enrolled into the early capsule and standard of care arms, respectively. There was no difference in total direct cost per inpatient case in both groups ($7,362 vs. $7,148, p = 0.77 [CI -2,285-2,315, equivalent margin -$3100]). Localization of a bleeding source after the first diagnostic procedure was identified more frequently in the early capsule group (69.2% vs. 27.9%, p = 0.0003). If patients were discharged after their last non-diagnostic evaluation, then length of stay could be decreased by 50% in both groups (58.5 to 31.6 hours, p = 0.02 in the early capsule group and 69.4 to 39.2 hours in the standard of care group p = 0.001). Projections indicate the fastest a patient with non-diagnostic evaluations could be discharged is 0.88 days in the early capsule group vs 1.63 days in the standard of care group (p = 0.0005). DISCUSSION: In patients with non-hematemesis bleeding, video capsule endoscopy may be a more efficient diagnostic approach than the standard of care approach, since it detects bleeding significantly more often without an increase in health care costs.

description: We model molecular outflows produced by the time dependent interaction between a stellar wind and a rotating cloud envelope in gravitational collapse, studied by Ulrich. We consider spherical and anisotropic stellar winds. We assume that the bipolar outflow is a thin shocked shell, with axial symmetry around the cloud rotation axis and obtain the mass and momentum fluxes into the shell. We solve numerically a set of partial differential equations in space and time, and obtain the shape of the shell, the mass surface density, the velocity field, and the angular momentum of the material in the shell. We find that there is a critical value of the ratio between the wind and the accretion flow momentum rates $β$ that allows the shell to expand. As expected, the elongation of the shells increase with the stellar wind anisotropy. In our models, the rotation velocity of the shell is the order to 0.1 - 0.2 km s$^{-1}$, a factor of 5-10 lower than the values measured in several sources. We compare our models with those of Wilkin and Stahler for early evolutionary times and find that our shells have the same sizes at the pole, although we use different boundary conditions at the equator.

description: This paper tests the sensitivity of poverty indexes to the choice of adult equivalence scales, assumptions about the existence of economies of scale in consumption, methods for treating missing and zero incomes, and different adjustments to handle income miss reporting. We also perform sensitivity analysis to the use of different poverty lines and poverty indexes, which are issues that have been much more explored in the literature. The sensitivity analysis is applied to household survey data from 17 Latin American countries, which include 92% of the population in the region. By varying these parameters within reasonable boundaries, we find that the proportion of poor could be said to be either 12.7 percent or 65.8 percent of the total population. Additionally, the ranking of counties with respect to poverty is also highly sensitive. This points to the need of justifying and being explicit about the underlying choices and definitions behind poverty statistics, and to the need of performing sensitivity analysis illustrating the menu of options that can answer the question of how much poverty there is.
Growing fluctuation of quantum weak invariant and dissipation

description: The concept of weak invariants has recently been introduced in the context of conserved quantities in finite-time processes in nonequilibrium quantum thermodynamics. A weak invariant itself has a time-dependent spectrum, but its expectation value remains constant under time evolution defined by a relevant master equation. Although its expectation value is thus conserved by definition, its fluctuation is not. Here, time evolution of such a fluctuation is studied. It is shown that if the subdynamics is given by a completely positive map, then the fluctuation of the associated weak invariant does not decrease in time. It is also shown, in the case of the Lindblad equation, how the growth rate of the fluctuation is connected to the dissipator. As examples, the harmonic oscillator with a time-dependent frequency and the spin in a varying external magnetic field are discussed, and the fluctuations of their Hamiltonians as the weak invariants are analyzed. Furthermore, a general relation is presented for the specific heat and temperature of any subsystem near equilibrium following the slow Markovian isoenergetic process.

title: Effect of crude oil on defence-relevant biomarker gene expression in early-life stage lumpfish

description: This thesis investigated the response of early-life stage lumpfish (i.e., larval and juvenile) to crude oil at the mRNA level. A pilot study was conducted on juvenile lumpfish, which were exposed to five chemically-enhanced water-accommodated fraction (CEWAF) treatments for 24 h in a static system. Through multiple sequence alignment (MSA), phylogenetic and synteny analyses, five lumpfish aryl hydrocarbon receptor genes were studied and named following those in Japanese pufferfish (Takifugu rubripes). The results of real-time quantitative polymerase chain reaction (qPCR) showed significant induction for ahr1a, ahr2a and cyp1a1 in the liver of oil-exposed juvenile lumpfish. Based on these results, another exposure experiment was done on 50 days post-hatch lumpfish larvae in a similar exposure set-up, with two additional CEWAF treatments. The qPCR results indicated that the 24-h CEWAF exposure might modulate immune and redox function in larval lumpfish. Moreover, a Spearman correlation analysis and principal component analysis suggested that Ahr may affect the expression of genes involved in cardiovascular development and immune response. Collectively, these results provide new insight into the influence of acute crude oil exposure on the transcript levels of targeted genes in larval and juvenile lumpfish.

description: A broad variety of liquids conform to density scaling: relaxation times expressed as a function of the ratio of temperature to density, the latter raised to a material constant γ. For atomic liquids interacting only through simple pair potentials, the exponent γ is very nearly equal to n/3, where n is the steepness of the intermolecular potential, while for molecular liquids having rigid bonds and built using the same interatomic potential, γ>n/3. We find that for this class of molecular liquids γ=n/δ, where the parameter δ relates the intermolecular distance to the density along an isomorph (line of approximately constant dynamics and structure). δ depends only on the molecular structure and not the interatomic potential.
