description: Dependency quantified Boolean formulas (DQBFs) are a generalization of QBFs, which allows to have existential variables that depend on arbitrary subsets of the universal variables. We present an effective way to solve such DQBFs by eliminating individual dependencies such that an equisatisfiable QBF is obtained, which can be solved by an arbitrary QBF solver. We also present how to use dependency schemes in order to obtain smaller equisatisfiable QBFs, which can typically be solved more efficiently.

description: This book, based on the work carried out by CREDA and other partners within Blue Bio Med, describes the governance developed within the Work Package 4 of the project model (Fernández-Guerrero et al., 2022b); the work package was devoted to the implementation and testing of a policy experiments methodology aimed at promoting multi-stakeholder collaboration on innovation, addressing sustainable development challenges related to the blue bioeconomy, in the Mediterranean. Based on a (i) literature review of the foundations provided by the literature on innovation and sustainability transitions; (ii) the analysis of current governance arrangements and (iii) the comparative analysis of the policy experiments carried out within Blue Bio Med, this document aims to propose a governance model suitable for the promotion of transformative innovation through multi-stakeholder collaboration at different governance levels, across the Mediterranean basin.

description: Quantized Hall conductance is a generic feature of two dimensional electronic systems with broken time reversal symmetry. In the quantum anomalous Hall state recently discovered in magnetic topological insulators, time reversal symmetry is believed to be broken by long-range ferromagnetic order, with quantized resistance observed even at zero external magnetic field. Here, we use scanning nanoSQUID magnetic imaging to provide a direct visualization of the dynamics of the quantum phase transition between the two anomalous Hall plateaus in a Cr-doped (Bi,Sb)$_2$Te$_3$ thin film. Contrary to naive expectations based upon macroscopic magnetometry, our measurements reveal a superparamagnetic state formed by weakly interacting magnetic domains with a characteristic size of few tens of nanometers. The magnetic phase transition occurs through random reversals of these local moments, which drive the electronic Hall plateau transition. Surprisingly, we find that the electronic system can in turn drive the dynamics of the magnetic system, revealing a subtle interplay between the two coupled quantum phase transitions.

description: In this work we study families of pairs of window functions and lattices which lead to Gabor frames which all possess the same frame bounds. To be more precise, for every generalized Gaussian $g$, we will construct an uncountable family of lattices $\lbrace Λ_τ\rbrace$ such that each pairing of $g$ with some $Λ_τ$ yields a Gabor frame, and all pairings yield the same frame bounds. On the other hand, for each lattice we will find a countable family of generalized Gaussians $\lbrace g_i \rbrace$ such that each pairing leaves the frame bounds invariant. Therefore, we are tempted to speak about "Gabor Frame Sets of Invariance".

description: This literature review provides an overview of various areas of research in database  migration. Specific areas which are addressed are legacy migration, migrating between  different database models, reverse engineering, schema design and translation, and  security. Additional literature is considered which provides a general overview of the  topic. Some case study literature is included with an emphasis on library science studies.  This literature review is then applied to a case study migration project at the University of  North Carolina at Chapel Hill in order to determine where the literature was helpful and  where not, as well as where more research may be needed. Conclusions are drawn that  the theoretical literature is quite comprehensive, but that literature having more practical  application could certainly be strengthened.

description: Telomere attrition is considered a useful indicator of cellular and whole-organism ageing rate. While approximately 80% of animal species undergo metamorphosis that includes extensive tissue transformations (involving cell division, apoptosis, de-differentiation and de novo formation of stem cells), the effect on telomere dynamics is unknown. We measured telomeres in Xenopus laevis developing from larvae to adults under contrasting environmental temperatures. Telomere dynamics were linked to the degree of tissue transformation during development. Average telomere length in gut tissue increased dramatically during metamorphosis, when the gut shortens by 75% and epithelial cells de-differentiate into stem cells. In the liver (retained from larva) and hindlimb muscle (newly formed before metamorphosis), telomeres gradually shortened until adulthood, likely due to extensive cell division. Tail muscle telomere lengths were constant until tail resorption, and those in heart (retained from larva) showed no change over time. Telomere lengths negatively correlated with larval growth, but for a given growth rate, telomeres were shorter in cooler conditions, suggesting that growing in the cold is more costly. Telomere lengths were not related to post-metamorphic growth rate. Further research is now needed to understand whether telomere dynamics are a good indicator of ageing rate in species undergoing metamorphosis.

description: This study identifies cultural differences upon web interface design of corporate  web sites by conducting a content analysis of the web design features generated  from Geert Hofstede's cultural dimensions. To achieve this goal, this study  develops a series of web design evaluating standards that reflect cultural values.  Sixteen corporate web sites, eight from China and eight from the United states,  are selected for the study to represent four main industries: telecommunication,  petroleum, computer and banking. Four of Hofstede's cultural dimensions that are  used as theoretical basis are: power distance, collectivism vs. individualism,  femininity vs. masculinity, and long-term vs. short-term orientation. The results  show that cultural influences are deeply inseminated throughout the web interface  design of corporate web sites from different cultures. A complete understanding  of the cultural differences and an effective implementation of cultural design will  be essential for businesses' survival and growth nowadays and henceforward.

description: We propose to apply spin noise spectroscopy (SNS) to detect many-body localization (MBL) in disordered spin systems. The SNS methods are relatively non-invasive technique to probe spontaneous spin fluctuations. We here show that the spin noise signals obtained by cross-correlation SNS with two probe beams can be used to separate the MBL phase from a noninteracting Anderson localized phase and a delocalized (diffusive) phase in the studied models for which we numerically calculate real time spin noise signals and their power spectra. For the archetypical case of the disordered XXZ spin chain we also develop a simple phenomenological model.

description: This study determined the differences between users’ and librarians’ use, beliefs about
importance, and satisfaction with services in one public library system. It also assessed
whether librarians accurately gauge the users’ perspectives. 51 library users and 18
librarians participated in the study. The results indicate that these users and librarians use
services to different extents and have different beliefs about the importance of services.
The librarians did not accurately gauge users’ use or satisfaction with some services.
However, these users and librarians have similar levels of satisfaction with many services
and the librarians accurately gauged the users’ beliefs about importance of most services.
This research suggests a new direction for library service evaluation: taking the
librarians’ perspectives into account.

Database management systems

description: This paper suggests that relational database-driven systems in the library or information center should be valued not only for the improvements to customer service they can provide, but also for the rich store of data held in these systems which can be queried and used in collection analysis. MyLibrary@NCState is an open source, relational database-driven system that allows users to customize their access to a library's electronic resources and current awareness services. Its backend MySQL database can be queried to show, for example, which electronic journals appear on the most user pages, which bibliographic databases or reference shelf items have been selected the most within a particular range of dates, and which resources are underused. Libraries and information centers can then use these data as a starting point to locate resources for cancellation or those resources needing additional marketing efforts. Results from queries of MyLibrary@NCState's MySQL database as of March 28, 2001 are presented and discussed.

description: Pure and Nb-doped TiO2 photocatalysts with highly ordered alternating gyroid architecture and well-controllable mesopore size of 15 nm via co-assembly of a poly(isoprene)-block-poly(styrene)-block-poly(ethylene oxide) block copolymer are synthesized. A combined effort by electron microscopy, X-ray scattering, photoluminescence, X-ray photoelectron spectroscopy, Raman spectroscopy, and density functional theory simulations reveals that the addition of small amounts of Nb results in the substitution of Ti4+ with isolated Nb5+ species that introduces inter-bandgap states, while at high concentrations, Nb prefers to cluster forming shallow trap states within the conduction band minimum of TiO2. The gyroidal photocatalysts are remarkably active toward hydrogen evolution under UV and visible light due to the open 3D network, where large mesopores ensure efficient pore diffusion and high photon harvesting. The gyroids yield unprecedented high evolution rates beyond 1000 µmol h−1 (per 10 mg catalyst), outperforming even the benchmark P25-TiO2 more than fivefold. Under UV light, the Nb-doping reduces the activity due to the introduction of charge recombination centers, while the activity in the visible triple upon incorporation is owed to a more efficient absorption due to inter-bandgap states. This unique pore architecture may further offer hitherto undiscovered optical benefits to photocatalysis, related to chiral and metamaterial-like behavior, which will stimulate further studies focusing on novel light–matter interactions.
Relativistic effects and primordial non-Gaussianity in the matter density fluctuation

description: We present the third-order analytic solution of the matter density fluctuation in the proper-time hypersurface of nonrelativistic matter flows by solving the nonlinear general relativistic equations. The proper-time hypersurface provides a coordinate system that a local observer can set up without knowledge beyond its neighborhood, along with physical connections to the local Newtonian descriptions in the relativistic context. The initial condition of our analytic solution is set up by the curvature perturbation in the comoving gauge, clarifying its impact on the nonlinear evolution. We compute the effective non-Gaussian parameters due to the nonlinearity in the relativistic equations. With proper coordinate rescaling, we show that the equivalence principle is respected and the relativistic effect vanishes in the large-scale limit.

description: Reversible adhesion is the key functionality to grip, place, and release objects nondestructively. Inspired by nature, micropatterned dry adhesives are promising candidates for this purpose and have attracted the attention of research groups worldwide. Their enhanced adhesion compared to nonpatterned surfaces is frequently demonstrated. An important conclusion is that the contact mechanics involved is at least as important as the surface energy and chemistry. In this paper, the roles of the contact geometry and mechanical properties are reviewed. With a focus on applications, the effects of substrate roughness and of temperature variations, and the long-term performance of micropatterned adhesives are discussed. The paper provides a link between the current, detailed understanding of micropatterned adhesives and emerging applications.

description: It has been proposed that a recent outburst of cosmic-ray electrons could account for the excess of GeV-scale gamma rays observed from the region surrounding the Galactic Center. After studying this possibility in some detail, we identify scenarios in which a series of leptonic cosmic-ray outbursts could plausibly generate the observed excess. The morphology of the emission observed outside of $\sim1^{\circ}-2^{\circ}$ from the Galactic Center can be accommodated with two outbursts, one which took place approximately $\sim10^6$ years ago, and another (injecting only about 10\% as much energy as the first) about $\sim10^5$ years ago. The emission observed from the innermost $\sim1^{\circ}-2^{\circ}$ requires one or more additional recent outbursts and/or a contribution from a centrally concentrated population of unresolved millisecond pulsars. In order to produce a spectrum that is compatible with the measured excess (whose shape is approximately uniform over the region of the excess), the electrons from the older outburst must be injected with significantly greater average energy than those injected more recently, enabling their spectra to be similar after $\sim10^6$ years of energy losses.

description: English language learners represent a growing population that requires educators to take a serious look at instructional programs to support these students' learning. The issue of educating these students has received increased emphasis due to the requirements of the No Child Left Behind Act and schools' accountability for achievement of various student populations. English language learner students are at an obvious academic disadvantage since content area curriculum is typically taught in English. This study will focus on theories of language acquisition, strategies to support the needs of English language learner teacher and learners, and specifically look at the library's role in providing resources.
Adjoint Fokker-Planck equation and runaway electron dynamics

description: The adjoint Fokker-Planck equation method is applied to study the runaway probability function and the expected slowing-down time for highly relativistic runaway electrons, including the loss of energy due to synchrotron radiation. In direct correspondence to Monte Carlo simulation methods, the runaway probability function has a smooth transition across the runaway separatrix, which can be attributed to effect of the pitch angle scattering term in the kinetic equation. However, for the same numerical accuracy, the adjoint method is more efficient than the Monte Carlo method. The expected slowing-down time gives a novel method to estimate the runaway current decay time in experiments. A new result from this work is that the decay rate of high energyelectrons is very slow when E is close to the critical electric field. This effect contributes further to a hysteresis previously found in the runaway electron population.

description: Small scale bed flow photoreactor experiments were performed to assess the photocatalytic performance of cement-based TiO2-containing materials for NOx reduction through the determination of kinetic parameters under variation of the experimental conditions (relative humidity, flow rate, mixing ratio and light intensity) and monitoring of potential reaction products in the gas phase and the aqueous extract of the surface. The results clearly demonstrated the general potential of the tested material to photocatalytically remediate gas phase NOx by conversion into nitrite and nitrate as identified reaction products at the surface. The measured uptake coefficients for NO and NO2 under atmospheric relevant conditions were in the range of 5 × 10−5 with a corresponding surface deposition velocity of about 0.5 cm s−1. However, it became also clear that the photocatalytic activity is in part significantly dependent on the experimental conditions. The relative humidity and the mixing ratio of the air pollutant were identified as the most important parameters. In addition, under certain conditions, a renoxification process can occur. The comprehensive results of the present study are discussed in detail to develop recommendations for a possible future application of this technique to improve urban air quality.

 Gaikwad et al. 2009, p. 103. Pl. 1, figs 1–5.
 Distribution in India: Maharashtra (Pune city, on moist soils at Regional Fruit Research Centre).
 Notes: The report of Porphyridium from India (Gaikwad et al. 2009), especially from a terrestrial humid soil environment is significant, since the only earlier record of a unicellular (or a coccoid / palmelloid habit ensheathed in distinct mucilage) red alga is that of Iyengar (1985) of Chroothece richteriana Hansgrig (see below). Gaikwad et al. (2009) indicated that, although the material was collected from an inland area (> 600 m elevation) and far removed from the sea, they were able to grow it successfully in a culture medium with a normal seawater salt concentration (30 mg / l). Islam (1992) reported P. purpureum earlier from neighbouring Bangladesh. Ott (2009) provided a detailed discussion on the validity of Porphyridium (including the legitimacy of P. purpureum versus P. cruentum (Gray) Nägeli as the type species of the genus). Porphyridium, and some other unicellular genera like Dixoniella Scott, Broadwater, B.D. Saunders, Thomas & Gabrielson and Erythrolobus Scott, Baca, Ott & J.A.West were cultured in mass scale and studied for LMWCs (low molecular weight carbohydrates) like mannitol (Eggert et al. 2007), phycobiliproteins, fatty acid composition, tocopherols, polyunsaturated fatty acids and extra cellular proteoglycan (EPG), that have applications in the food, pharmaceutical and cosmetic industries (Durmaz et al. 2007; Capek et al. 2008). It would be worthwhile to isolate and characterize the specimens from Pune for future use in applied studies in India. Previously, such studies in India were based on a culture of Porphyridium (culture SAG 112.79) from another region and maintained in the Pflanzenphysiolgisches Institute, Universität Göttingen, Germany (Kathiresan et al. 2006).

Field research for the study was guided by an observational rubric of key accessibility features with the aim of finding patterns in their implementation or absence. The results indicate major gaps in the basic Spanish-language service within most of the libraries as well as a profound degree of variability between offered services at each. Future improvement calls for a pragmatic understanding of foreign language perspective and the need for better interlibrary communication.

description: In general, sorting networks can be used as interconnection networks in that the inputs are simply sorted according to their target addresses. If the target addresses form a permutation of the addresses, this is obviously correct since the sorting algorithm routes each message to the output with the desired target address. However, if not all inputs need a connection to one of the outputs, partial permutations are obtained since then some input addresses are not mapped to any output address at all. In this case, sorting networks work no longer correctly as interconnection networks since the addresses larger than the missing addresses will be routed to the wrong outputs. For merge-based sorting networks, there is a well-known general solution called the Batcher-Banyan network. However, for the bigger class of radix-based sorting networks, there is only one solution known for a particular permutation network. In this paper, we present a general construction to transform any radix-based sorting network into one that can cope with partial permutations. While our solution roughly doubles the number of gates, it still maintains the depth of the circuit.

description: Background: Messenger RNA (mRNA) has gained remarkable attention as an alternative to DNA-based therapies in biomedical research. A variety of biodegradable nanoparticles (NPs) has been developed including lipid-based and polymer-based systems for mRNA delivery. However, both systems still lack in achieving an efficient transfection rate and a detailed understanding of the mRNA transgene expression kinetics. Therefore, quantitative analysis of the time-dependent translation behavior would provide a better understanding of mRNA's transient nature and further aid the enhancement of appropriate carriers with the perspective to generate future precision nanomedicines with quick response to treat various diseases. Results: A lipid-polymer hybrid system complexed with mRNA was evaluated regarding its efficiency to transfect dendritic cells (DCs) by simultaneous live cell video imaging of both particle uptake and reporter gene expression. We prepared and optimized NPs consisting of poly (lactid-co-glycolid) (PLGA) coated with the cationic lipid 1, 2-di-O-octadecenyl-3-trimethylammonium propane abbreviated as LPNs. An earlier developed polymer-based delivery system (chitosan-PLGA NPs) served for comparison. Both NPs types were complexed with mRNA-mCherry at various ratios. While cellular uptake and toxicity of either NPs was comparable, LPNs showed a significantly higher transfection efficiency of ~ 80% while chitosan-PLGA NPs revealed only ~ 5%. Further kinetic analysis elicited a start of protein translation after 1 h, with a maximum after 4 h and drop of transgene expression after 48 h post-transfection, in agreement with the transient nature of mRNA. Conclusions: Charge-mediated complexation of mRNA to NPs enables efficient and fast cellular delivery and subsequent protein translation. While cellular uptake of both NP types was comparable, mRNA transgene expression was superior to polymer-based NPs when delivered by lipid-polymer NPs.

description: Chroodactylon depressum (G. Martens) V. Krishnamurthy, M.S. Balakrishnan & T.V. Desikachary
 Desikachary et al. 1990, Part II A, p. 10; Ott 2009, p. 252.
 Taxonomic synonym: Allogonium depressum: Martens 1870a, p. 12; Srinivasan 1965, p. 244.
 Distribution in India: West Bengal (northern Bengal between Silligore and Titalya in stagnant waters, forming a dense covering on water plants intermixed with blue-green algae).
 Notes: Asterocytis is not currently accepted as a valid generic name and the two species referred to that genus are now assigned to Chroodactylon. Two species of Chroodactylon [C. wolleanum Hansgirg and C. ornatum (C. Ag.) Basson] currently appear to be well recognized and the Indian C. depressum is “treated as a provisional entry and has not been subject to verification” (Guiry & Guiry 2017). Following Ross (Drew & Ross 1965) and recent authors (Schneider & Wynne, 2007; Ott 2009; Silva 2017 and Guiry & Guiry 2017), we also consider generic names (Allogonium, Asterocytis, Callonema, Glauconema and Chroodacytlon) represent a single generic entity and that Chroodactylon has priority over other names. Described as early as 1870, based on the first (and probably the only collection made so far) from “Lower Bengal”, C. depressum continues to be a very poorly known species to date. Silva (2017) noted that the collector was Mr. S. Kurz in 1894 at a place “between Silligore and Titalya, northern Bengal, India ”. This place is apparently free from any tidal influence from the Bay of Bengal and would appear that it was collected from a truly freshwater habitat. More importantly, Silva et al. (1996) did not include this speceis in their Indian Ocean Marine Algal Catalog, clearly suggesting a freshwater or non–marine habitat. However, the citation as “Lower Bengal” by Desikachary et al. (1990) based on Martens (1870a) apparently is an error. It should be noted that the term “Lower Bengal” was used in earlier literature mostly to encompass Kolkata (formerly Calcutta) and adjoining areas including brackish ponds at Port Canning. After the original description by Martens, this species was not collected subsequently from India or neighboring countries. Clearly, the Indian specimens referred to as C. depressum need more critical and comparative study, especially examination of Kurz’s original collection, if it is still traceable in European herbaria. Wynne (pers. comm.) suggested LE (Leningrad) as a possible place for the specimens of the original collection.

description: The intrinsic column density (NH) distribution of quasars is poorly known. At the high obscuration end of the quasar population and for redshifts z<1, the X-ray spectra can only be reliably characterized using broad-band measurements which extend to energies above 10 keV. Using the hard X-ray observatory NuSTAR, along with archival Chandra and XMM-Newton data, we study the broad-band X-ray spectra of nine optically selected (from the SDSS), candidate Compton-thick (NH > 1.5e24 cm^-2) type 2 quasars (CTQSO2s); five new NuSTAR observations are reported herein, and four have been previously published. The candidate CTQSO2s lie at z<0.5, have observed [OIII] luminosities in the range 8.4 < log (L_[OIII]/L_solar) < 9.6, and show evidence for extreme, Compton-thick absorption when indirect absorption diagnostics are considered. Amongst the nine candidate CTQSO2s, five are detected by NuSTAR in the high energy (8-24 keV) band: two are weakly detected at the ~ 3 sigma confidence level and three are strongly detected with sufficient counts for spectral modeling (>~ 90 net source counts at 8-24 keV). For these NuSTAR-detected sources direct (i.e., X-ray spectral) constraints on the intrinsic AGN properties are feasible, and we measure column densities ~2.5-1600 times higher and intrinsic (unabsorbed) X-ray luminosities ~10-70 times higher than pre-NuSTAR constraints from Chandra and XMM-Newton. Assuming the NuSTAR-detected type 2 quasars are representative of other Compton-thick candidates, we make a correction to the NH distribution for optically selected type 2 quasars as measured by Chandra and XMM-Newton for 39 objects. With this approach, we predict a Compton-thick fraction of f_CT = 36^{+14}_{-12} %, although higher fractions (up to 76%) are possible if indirect absorption diagnostics are assumed to be reliable.

description: We measure the dissipation and frequency shift of a magnetically coupled cantilever in the vicinity of a silicon chip, down to $25$ mK. The dissipation and frequency shift originates from the interaction with the unpaired electrons, associated with the dangling bonds in the native oxide layer of the silicon, which form a two dimensional system of electron spins. We approach the sample with a $3.43$ $μ$m-diameter magnetic particle attached to an ultrasoft cantilever, and measure the frequency shift and quality factor as a function of temperature and the distance. Using a recent theoretical analysis [J. M. de Voogd et al., arXiv:1508.07972 (2015)] of the dynamics of a system consisting of a spin and a magnetic resonator, we are able to fit the data and extract the relaxation time $T_1=0.39\pm0.08$ ms and spin density $σ=0.14\pm0.01$ spins per nm$^2$. Our analysis shows that at temperatures $\leq500$ mK magnetic dissipation is an important source of non-contact friction.

description: Remote hilly hamlets in India still face acute energy security problems. As a solution, the present study discusses a Novel Hybrid Solar Pumped Storage Powerplant that can operate in grid-connected and standalone modes to provide stable power throughout the year. Genetic algorithm-based optimization techniques and actual resource and demand data were utilized to optimize the system’s design. Site-specific power generation and grid interaction models were established and multiple operational modes of the system were simulated with a system dynamics modeling approach. Results show a 73% reduction in greenhouse emissions, a levelized energy cost of 0.09$/kWh, and assured generation security of 82% during standalone operation. The probability of power supply loss during the grid-connected operation was minimized, and 20% was incurred during standalone operation. This innovative solution can provide reliable and sustainable power to remote hilly hamlets, contributing to the Sustainable Development Goal (SDG)-7 and helping India achieve its COP-26 & 27 commitments. As the government takes active initiatives to improve grid stability in remote locations, this system can be effectively implemented and scaled up to provide a cost-effective and environmentally friendly solution for storage and utilization of solar power.
