description: The rheology of non-colloidal suspensions under cyclic shear is studied numerically. The main findings are a strain amplitude ($γ_0$) dependent response in the shear stress and second normal stress difference ($N_2$). Specifically, we find a reduced viscosity, an enhanced intracycle shear thinning, the onset of a finite $N_2$ and its frequency doubling, all near a critical strain amplitude $γ_c$ that scales with the volume fraction $ϕ$ as $γ_c \sim ϕ^{-2}$. These rheological changes also signify a reversible-irreversible transition (RIT), dividing stroboscopic particle dynamics into a reversible absorbing phase (for $γ_0<γ_c$) and a persistently diffusing phase (for $γ_0>γ_c$). We explain the results based on two flow-induced mechanisms and elucidate their connection in the context of RIT through the underlying microstructure, which tends towards hyperuniformity near $γ_0=γ_c$. Overall, we expect this correspondence between rheology and emergent dynamics to hold in a wide range of settings where structural organizations are dominated by volume exclusions.

description: Quantum computers have the potential to solve some important industrial and scientific problems with greater efficiency than classical computers. While most current realizations focus on two-level qubits, the underlying physics used in most hardware is capable of extending the concepts to a multi-level logic - enabling the use of qudits, which promise higher computational power and lower error rates. Based on a strong theoretical backing and motivated by recent physical accomplishments, this also calls for methods and tools for compiling quantum circuits to those devices. To enable efficient qudit compilation, we introduce the concept of an energy coupling graph for single-qudit systems and provide an adaptive algorithm that leverages this representation for compiling arbitrary unitaries. This leads to significant improvements over the state-of-the-art compilation scheme and, additionally, provides an option to trade-off worst-case costs and run-time. The developed compiler is available via github.com/cda-tum/qudit-compilation under an open-source license.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The aim of this work was to build up starch-based bioactive films from corn starch, glycerol, citric acid, and cinnamon bark oleoresin and characterize its physical and mechanical properties, and check its antimicrobial effect. The processing variables were optimized to study their effect on the functional properties of bio- films. Glycerol concentration (20, 30, & 40%v/w), citric acid concentration (0, 5, & 10%w/w), and drying temperature (30, 60, & 90oc) as independent variables which produced 20 different combinations, were studied using response surface methodology to investigate the effect of these variables on the product responses. The glycerol concentration was the most influential parameter for the physical and mechanical properties of the prepared packaging films followed by citric acid concentration and drying temperature. The numerical optimization gave in glycerol concentration (27.86ml glycerol/100g corn starch), citric acid concentration (0.29g citric acid/100g corn starch), and drying temperature (62.84oc) as optimum variables to produce better films. Using the optimized variables the films were re-prepared and the functional groups were identified using FTIR. The bio-films were again prepared using the optimized variables with the addition of Cinnamon bark oleoresin (0%, 10%, and 12% v/w of dry starch) in order to analyze its antimicrobial activities against the target microorganisms Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. The cinnamon bark oleoresin showed clear inhibition zone against the tested microorganisms whereas the bio-films containing the oleoresin showed surface inhibition.

description: H. meteorou Hinz & Sterrenburg, sp. nov. (Figs 16, 17: LM, 39–46: SEM)
 Type:— “ SM338 IOE “Meteor” Sta. # 103, 170-0m, 20-12-1964, geographic coordinates 11°27,5’N 53°04,5’E. Holotype BRM SIM 64 /43, slide coordinates (benchmark left upper corner of coverslip) 13.2 E, 6.0 S, isotype coordinates 15.0 E, 7.3 S.
Valve (Figs 16, 17, 39, 40) lanceolate, 38–45 μm long, 7–10 μm wide, with acute ends. Striae transverse slightly radiate, 18–20 in 10 μm, longitudinal 14–16 in 10 μm. In LM, axial and central area very narrow. In SEM, the tegumental layer shows little relief (Figs 41, 44). External central raphe fissure endings approximate, tiny “crooks”, tightly curved over about 270° around a tooth-like projection (Figs 44, 46), apical endings undulating and terminate as retrograde depressed hooks (Fig. 41). At the apex 2–3 small accessory pores perforate the solid margin of the valve (Fig. 41, 42). Basal layer: foramina apically elongated oblong, longitudinal bars of the grate much broader than the foramina (Figs 42, 43). Entire internal raphe fissure and central raphe node (which is slightly depressed in the middle) tilted sideways (Figs 43, 45).
 Etymology:— The specific epithet, genitive of Greek “meteoros”, refers to the research vessel used by the expedition during which the material was collected.
 Habitat:— planktonic, marine.
 Distribution:— so far known from the type locality only, fairly rare in the sample.
 Observations: —In samples of the Meteor expedition discussed in Simonsen 1974, we found specimens resembling H. tsukamotoi in the peculiar central external raphe ending shapes and fully tilted central raphe node. There is no marked broadening of the internal areolar foramina near the margin, however, and transverse striation is much finer than the longitudinal, warranting separate taxonomic status. Simonsen (1974) does not describe such specimens under either Haslea or Navicula. In the specimen of Figs 41 and 44 valve development is not yet complete: infilling has resulted in narrow fissures at the periphery, but has not yet finished in the median portion of the valve. The specimen of Fig. 43 shows the final situation, with very narrow longitudinal fissures. Saepes not satisfactorily visualized, no fragmented valves found.
 H. meteorou has much coarser longitudinal than transverse striae, setting it apart in the genus Haslea.

Aedeagus: Figures 16 and 17; male sixth free tergite: Figure 18. Comparative notes The habitus and the aedeagus of the new species are similar to those of A. inducta Fauvel, 1907 from Tanzania, of which I have examined the male holotype labelled ‘Afrique Orient., Kilimanjaro (zones des forêts), Kibosho, 1700 m, Ch. Alluaud 1904, A. inducta Fvl., Type’ (IRSNB). The antennae of the two species are similar, and the apex of the aedeagus is narrow in both species in ventral view. The basal bulb of the aedeagus of the new species, however, is well developed, and that of A. inducta is reduced. The internal sclerotized structure of the aedeagus is completely different in the two species.

description: Recently, several quantum benchmarking algorithms have been developed to characterize noisy quantum gates on today's quantum devices. A well-known issue in benchmarking is that not everything about quantum noise is learnable due to the existence of gauge freedom, leaving open the question of what information about noise is learnable and what is not, which has been unclear even for a single CNOT gate. Here we give a precise characterization of the learnability of Pauli noise channels attached to Clifford gates, showing that learnable information corresponds to the cycle space of the pattern transfer graph of the gate set, while unlearnable information corresponds to the cut space. This implies the optimality of cycle benchmarking, in the sense that it can learn all learnable information about Pauli noise. We experimentally demonstrate noise characterization of IBM's CNOT gate up to 2 unlearnable degrees of freedom, for which we obtain bounds using physical constraints. In addition, we give an attempt to characterize the unlearnable information by assuming perfect initial state preparation. However, based on the experimental data, we conclude that this assumption is inaccurate as it yields unphysical estimates, and we obtain a lower bound on state preparation noise.

Comparative notes The spermatheca of the new species is similar in shape to that of A. alboguttata Bernhauer, 1915 from Tanzania, of which I have examined the type series (in FMNHC). The proximal portion of the spermatheca of the new species is, however, less developed and is in tightly coiled, whereas in A. alboguttata the proximal portion of the spermatheca is more loosely coiled. The apical umbilicus of the distal bulb of the spermatheca is cylindrical and conical at the apex, whereas it is entirely conical in A. alboguttata. The posterior half of the brown elytra of A. alboguttata is yellow, in the new species the elytra are brown with reddishbrown base.

description: Let $M_γ$ be a subcritical Gaussian multiplicative chaos measure associated with a general log-correlated Gaussian field defined on a bounded domain $D \subset \mathbb{R}^d$, $d \geq 1$. We find an explicit formula for its singularity spectrum by showing that $M_γ$ satisfies almost surely the multifractal formalism, i.e., we prove that its singularity spectrum is almost surely equal to the Legendre-Fenchel transform of its $L^q$-spectrum. Then, applying this result, we compute the lower singularity spectrum of the multifractal random walk and of the Liouville Brownian motion.

Effect of Moringa (Moringa stenopetala ) and Rosemary (Rosmarinus officinalis L.) Leaf Extracts on Ground Raw Beef Quality and Storage Stability
Creators: name: Gelebo, Rocho
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Global beef production and consumption have been increased rapidly in recent decades and it is becoming the first-choice source of protein. This study was done to investigate the effect of moringa and rosemary leaf extracts on ground raw beef quality and storage stability under refrigeration condition. The dried leaves of these plant species were extracted using 70% ethanol. The antioxidant analyses of moringa and rosemary leaf extracts revealed that they contain total polyphenol 38.67mg GAE/g and total flavonoids 10.51 mg QE/g for moringa, and 48.36 mg GAE/g and 12.40 mg QE/g for rosemary extract, respectively. These both extracts exhibited a considerable activity against Staphylococcus aureus and Escherichia coli, with the highest inhibition zone of 19.0 mm measured for rosemary leaf extract against Escherichia Coli. Furthermore, ground raw beef samples were treated with different concentrations (0%, 1.5%, 2.5% and 5%) of the two extracts in order to study their effects on the meat quality and storage stability. The extracts had significant effects on the proximate composition, pH, color and peroxide value of ground raw beef. The extracts also had significant effect on total viable counts (≈ 4% and 4.5% reduction for moringa and rosemary, respectively), Staphylococcus aureus (3.2% and 13.7% reduction for moringa and rosemary, respectively) and total coliform counts (17.2% and 8.6% reduction for moringa and rosemary, respectively) on the third storage day. With regard to the storage stability, the study indicated that the extracts did not prolong the shelf life of ground beef for more than three storage days if used at low concentrations, especially from microbial safety point of view. Overall, the effect of the extracts was enhanced with the increase in their concentrations.

description: Metasurfaces providing resonances arising from quasi-bound states in the continuum have been proposed as sensors in the THz band due to the existence of strong resonances characterized by high quality factors. Controlling geometrical parameters, the quality factor can be adjusted and, theoretically, designed at will. However, losses in materials critically bound the metasurface performance and limit the quality factor of the resonances. For this reason, all-dielectric metasurfaces have been proposed as an alternative to metal-dielectric structures to reduce losses and achieve extreme functionalities. When implemented by low-loss materials, these structures are usually considered lossless and proposed as ultrasensitive sensors in the THz band. In this paper, we examine the effect of losses in all-dielectric metasurfaces considering realistic materials and study the limitations in the quality factor. In addition, we compare the performance of these structures as sensors with a nanostructure supporting extraordinary optical transmission. Our results show that material loss, even in low-loss materials, severely limits the sensing performance in all-dielectric metasurfaces, and that their performance can be surpassed by structures supporting extraordinary optical transmission.

description: The general-relativistic phenomenon of spin-induced orbital precession has not yet been observed in strong-field gravity. Gravitational-wave observations of binary black holes (BBHs) are prime candidates, since we expect the astrophysical binary population to contain precessing binaries. Imprints of precession have been investigated in several signals, but no definitive identification of orbital precession has been reported in any one of the 84 BBH observations to date by the Advanced LIGO and Virgo detectors. Here we report the measurement of strong-field precession in the LIGO-Virgo-Kagra (LVK) gravitational-wave signal GW200129. The binary's orbit precesses at a rate ten orders of magnitude faster than previous weak-field measurements from binary pulsars. We also find that the primary black hole is likely highly spinning. According to current binary population estimates a GW200129-like signal is extremely unlikely, and therefore presents a direct challenge to many current binary formation models.

description: In the last decade several small and medium sized solar or waste heat driven chillers have been developed and brought to market. Nevertheless, in Central Europe where many of these chillers are installed, the required cooling period of buildings is rather short. By using them as a heat pump during winter time their operating period can be extended in order to shorten the payback period and increase the cost effectiveness, and at the same time, the benefit to the environment is increased. From a thermodynamical point of view it is possible to run a chiller also as a heat pump, but in practice there are restrictions in application due to the dependency of the driving temperature and the temperatures of heat source and heat sink. Using the example of a 10 kW H2O/LiBr absorption chiller, constraints of and demands on different possible peripheral systems (heat sources and heat sinks) for the reversible operation have been investigated. In the paper we present combinations which are favorable, and others which should be avoided from a primary energy point of view.

description: Der Begriff der „muttersprachlichen Logik“, der in diesem Beitrag eine wesentliche Rolle spielt, soll den Sachverhalt wiedergeben, dass die Intonationsmuster unserer Muttersprache und die mit ihnen verknüpften Funktionen (wie etwa: eine gefühlsneutrale Aussage, eine Betonung oder eine Frage zu verdeutlichen) eine ebenso untrennbare wie verbindliche Einheit bilden, sodass wir verständlicherweise geneigt sind, diese Muster auch dann noch für gültig zu erachten, wenn wir eine Fremdsprache lernen. Das heißt, dass es etwa Deutschen, die Chinesisch lernen, als geradezu „unlogisch“ erscheinen muss, beim Formulieren einer chinesischen Frage nicht auch – wie im Deutschen – einen steigenden Satzton zu verwenden. Deshalb konzentriert sich dieser Beitrag auf die besonderen Schwierigkeiten, die sich vor allem deutschsprachigen Lernenden in den Weg stellen, wenn sie ein nicht nur grammatisch standardgemäßes oder in der Wortwahl passendes, sondern auch ein in artikulatorischer Hinsicht korrektes Chinesisch sprechen lernen wollen. In Orientierung an typischen Fehlerbeispielen bzw. sog. „Lieblingsfehlern“ von Deutschen enthält der Beitrag einen Katalog gezielter Erklärungs- und Übungsformen, die einem „negativen Transfer“ der „Logik“ der deutschen Sprache auf die chinesische vorbeugen sollen.

description: High-fidelity two-qubit gates in quantum computers are often hampered by fluctuating experimental parameters. The effects of time-varying parameter fluctuations lead to coherent noise on the qubits, which can be suppressed by designing control signals with appropriate filter functions. Here, we develop filter functions for Mølmer-Sørensen gates of trapped-ion quantum computers that accurately predict the change in gate error due to small parameter fluctuations at any frequency. We then design the filter functions of frequency-modulated laser pulses, and compare this method with pulses that are robust to static offsets of the motional-mode frequencies. Experimentally, we measure the noise spectrum of the motional modes and use it for designing the filter functions, which improves the gate fidelity from 99.23(7)% to 99.55(7)% in a five-ion chain.

description: We study the interpolation analogue of the Hermite-Padé type I approximation problem. We provide its determinant solution and we write down the corresponding integrable discrete system as an admissible reduction of Hirota's discrete Kadomtsev-Petviashvili equations. Apart from the $τ$-function form of the system we provide its variant, which in the simplest case of dimension two reduces to the non-autonomous discrete-time Toda equations.

(Figures 23– 27) Holotype ♂, Gabon, Forêt de la Mondah, 0° 36 / 26 //N, 9 ° 19 /0 3 //E, 10 m a.s.l., Cap Esterias, about 20 km N of Libreville, 6-16.XII. 1995, leg. L. Bartolozzi and S. Taiti, num. mag. 1784, n. coll. 14814. Paratype: 1 ♀, same data, n. coll. 14815, MSNF. Description Length 2.9 mm. Body shiny, reddish, including antennae and legs. Eyes as long as the post-ocular region in dorsal view. Second antennomere shorter than the first, third longer than the second, fourth to ninth transverse and oval. Body devoid of reticulation except on the pronotum on which is very weak. Puncturation of the head dense and weak, absent on the longitudinal median band of the head and near the eyes, that of the pronotum dense and weak, grouped to the sides of the impunctate longitudinal median band, with some very weak and very fine punctures on the sides. Granulation of the elytra very fine and very weak, absent on the abdomen. Pronotum with a weak posterior median impression. Aedeagus: Figures 24 and 25; male sixth free tergite: Figure 26; spermatheca: Figure 27. Comparative notes The new species is attributable to the genus Neosmectonia Jacobson and Kistner, 1983, and is distinguished from N. angusticollis (Eppelsheim, 1885) from the Gold Coast, by the short antennae, with transverse intermediary antennomeres, whereas these are elongate in N. angusticollis. The aedeagus of the new species has a well-developed ‘crista apicalis’, which is absent in the aedeagus of N. angusticollis. The present comparison is based on the revision, including an illustration of the aedeagus of N. angusticollis, given by Jacobson and Kistner, 1983.

description: With the rise of the Black Lives Matter movement in 2020, the American Library Association revised its Code of Ethics to increase awareness of and recommend actions to promote diversity, equity, and inclusion. Still, given that past research into library service equality shows mixed findings, there is a need today more than ever before to examine if public libraries provide equitable online reference services. Based on an analysis of over one thousand email responses, we found that public libraries provided equal service to all users regardless of their gender and race most of the time; however, females received significantly more and friendlier responses than male users, and White users received more emails than Black users. White female users also received the most emails while Black male users received the least.
