description: Η κατάστρωση προγραμμάτων καταπολέμησης των γαστρεντερικών νηματωδών παρασίτων των μικρών μηρυκαστικών συχνά στηρίζεται στη διάγνωση όχι μόνο της ύπαρξης των αυγών των παρασίτων στα κόπρανα των ζώων, αλλά επιπλέον στον ποσοτικό προσδιορισμό (αριθμός αυγών ανά γραμμάριο κοπράνων) και στην ταυτοποίηση των γενών των προνυμφών με κοπρανοκαλλιέργεια. Ο σκοπός της έρευνάς μας ήταν η αξιολόγηση της πιθανής επίδρασης της διάρκειας συντήρησης των κοπράνων στους 4ºC στην αξιοπιστία του αποτελέσματος της ποσοτικής εξέτασης και της ταυτοποίησης των προνυμφών των παρασίτων. Δείγματα κοπράνων, προβάτων και αιγών, εξετάσθηκαν και καλλιεργήθηκαν φρέσκα (D0), αμέσως μετά τη συλλογή τους, στη συνέχεια συντηρήθηκαν στους 4 ºC και συνεχίσθηκε η εξέταση και η καλλιέργειά τους ανά εβδομάδα μέχρι 126 ημέρες (D126). Διαπιστώθηκε ότι τα αυγά διατηρήθηκαν όλο το χρονικό αυτό διάστημα, αλλά μετά την D21 ο αριθμός τους μειώθηκε σημαντικά συγκριτικά με αυτόν στα φρέσκα (P<0,05) κόπρανα. Η εξέλιξη των προνυμφών μειώθηκε σημαντικά, κυρίως του γένους Haemonchus μετά την D7 (P<0.05).
description: The diagnosis of gastrointestinal nematodes in small ruminants is usually based on the detection of eggs in the faeces, as well as on faecal egg counts and identification of genes larvae. The aim of this study was to evaluate the effect of storage at 4ºC on faecal egg counts and the number of third stage larvae. Faecal samples from sheep and goat flocks were used. They were cultivated either as fresh (D0), or after they have been preserved in the freezer at 4ºC. From the preserved faeces random samples were obtained and examined on weekly basis for a period up to 126 days of storage (D126). The results showed that the eggs in the stored faeces were well preserved up to 21 days, however, thereafter the numbers started to decline gradually with time. The development and survival of infective larvae was significantly declined. The latter was more evident concerning the genus Haemonchus after the 7th day of storage (P<0.05).
Application of stable isotope labeled diphenhydramine to study the pharmacokinetics and metabolism of diphenhydramine in pregnant, non-pregnant, and fetal sheep
Creators: name: Tonn, George Roger
Publisher: name: University of British Columbia

description: Diphenhydramine (DPHM), an antihistamine, has been used in pregnant women; however, information regarding its disposition in human pregnancy is lacking. Recently, detailed pharmacokinetic studies in pregnant sheep have demonstrated that DPHM readily crosses the ovine placenta, and is eliminated from the fetus by placental and non-placental pathways. The purpose of this study is to investigate the components of the fetal non-placental elimination (i.e., fetal renal and hepatic), and to compare these to the estimates obtained from adult sheep. Since stable isotope techniques were to be employed, synthesis of stable isotope labeled DPHM (i.e., [²H10]DPH0M) and its major metabolite diphenylmethoxyacetic acid (i.e., [²H10]DPM0A) was required. Next, gas chromatographic - mass spectrometric methods were developed to simultaneously measure either DPHM and [²H10]DPH0M, or DPMA and [²H10]DPM0A. The current study demonstrates that the measured fetal renal clearance of DPHM contributes only ~2% to the observed fetal non-placental clearance. Overall, the total non-placental clearance of DPHM measured by direct methods (i.e., pulmonary [Yoo, 1989] and renal) can account for ~10% of the non-placental clearance. Unlike adult sheep, where hepatic extraction of DPHM was ~93%, no significant extraction of DPHM by the fetal liver following umbilical venous administration was observed. Therefore, fetal hepatic elimination is not likely to account for the remainder of the fetal non-placental clearance. However, fetal hepatic in vitro metabolism of DPHM (to form N-demethyl DPHM and DPMA) suggests that the fetal liver is capable of DPHM biotransformation. Thus, the liver and possibly other organs may contribute at least a portion of the fetal non-placental clearance via DPHM biotransformation. It appears that only a small fraction of the fetal non-placental clearance of DPHM can be accounted for by fetal renal and pulmonary clearances. While the low renal clearance of intact DPHM is similar both in fetus and mother, large differences in the hepatic uptake and/or metabolism of DPHM were observed between mother and fetus. This suggests that the pathways for the non-placental elimination of DPHM differ in mother and fetus. Despite the advances made in this study, the components of the fetal non-placental clearance remains largely unknown, and requires further study.

description: The restoration of metallicity in the high-temperature, cubic phase of Li4C60 represents a remarkable feature for a member of the A4C60 family (A = alkali metal), invariably found to be insulators. Structural and resonance technique investigations on Li4C60 at T > 600 K, show that its fcc structure is associated with a complete (4e) charge transfer to C60 and a sparsely populated Fermi level. These findings not only emphasize the crucial role played by lattice symmetry in fulleride transport properties, but also re-dimension the role of Jahn-Teller effects in band structure determination. Moreover, they suggest the present system as a potential precursor to a new class of superconducting fullerides.

description: We show that one can employ well-established numerical continuation methods to efficiently calculate the phase diagram for thermodynamic systems. In particular, this involves the determination of lines of phase coexistence related to first order phase transitions and the continuation of triple points. To illustrate the method we apply it to a binary Phase-Field-Crystal model for the crystallisation of a mixture of two types of particles. The resulting phase diagram is determined for one- and two-dimensional domains. In the former case it is compared to the diagram obtained from a one-mode approximation. The various observed liquid and crystalline phases and their stable and metastable coexistence are discussed as well as the temperature-dependence of the phase diagrams. This includes the (dis)appearance of critical points and triple points. We also relate bifurcation diagrams for finite-size systems to the thermodynamics of phase transitions in the infinite-size limit.

description: The recursive expansion of tree level multitrace Einstein-Yang-Mills (EYM) amplitudes induces a refined graphic expansion, by which any tree-level EYM amplitude can be expressed as a summation over all possible refined graphs. Each graph contributes a unique coefficient as well as a proper combination of color-ordered Yang-Mills (YM) amplitudes. This expansion allows one to evaluate EYM amplitudes through YM amplitudes, the latter have much simpler structures in four dimensions than the former. In this paper, we classify the refined graphs for the expansion of EYM amplitudes into $\text{N}^{\,k}$MHV sectors. Amplitudes in four dimensions, which involve $k+2$ negative-helicity particles, at most get non-vanishing contribution from graphs in $\text{N}^{\,k'(k'\leq k)}$MHV sectors. By the help of this classification, we evaluate the non-vanishing amplitudes with two negative-helicity particles in four dimensions. We establish a correspondence between the refined graphs for single-trace amplitudes with $(g^-_i,g^-_j)$ or $(h^-_i,g^-_j)$ configuration and the spanning forests of the known Hodges determinant form. Inspired by this correspondence, we further propose a symmetric formula of double-trace amplitudes with $(g^-_i,g^-_j)$ configuration. By analyzing the cancellation between refined graphs in four dimensions, we prove that any other tree amplitude with two negative-helicity particles has to vanish.

description: Macroscopic arrays of cold atoms trapped in optical cavities can reach the strong atom-light collective coupling regime thanks to the simultaneous interactions of the cavity mode with the atomic ensemble. In a recent work we reported a protocol that takes advantage of the strong and collective atom-light interactions in cavity QED systems for precise electric field sensing in the optical domain. We showed that it can provide between $10$-$20$~dB of metrological gain over the standard quantum limit in current cavity QED experiments operating with long-lived alkaline-earth atoms. Here, we give a more in depth discussion of the protocol using both exact analytical calculations and numerical simulations, and describe the precise conditions under which the predicted enhancement holds after thoroughly accounting for both photon loss and spontaneous emission, natural decoherence mechanisms in current experiments. The analysis presented here not only serves to benchmark the protocol and its utility in cavity QED arrays but also sets the conditions required for its applicability in other experimental platforms such as arrays of trapped ions.

A comparative study of alternative methods for efficiency measurement with applications to the transportation industry
Creators: name: Yu, Chunyan
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is concerned with measuring and explaining the productive efficiency of firms or organizations. In particular, the study compares three alternative methods of measuring efficiency, namely, the deterministic frontier method, the stochastic frontier method, and the data envelopment analysis method (DEA). The dissertation consists of two parts. In Part I, the relative merits of the three methods are discussed and evaluated through a Monte Carlo study under certain known conditions. The study focuses on the effects of exogenous variables on efficiency estimates. The results show that the stochastic frontier method generally produces better efficiency estimates than the other two methods. The DEA, however, has a slight advantage in cases where there are weak input substitution and large variations in input variables. In Part II, the three methods are examined empirically through their applications to a panel of 19 railways in OECD countries and a panel of 36 international airlines. Comparison of the three sets of efficiency estimates confirms that on average the stochastic frontier method yields higher efficiency estimates than the other two methods, as indicated by the Monte Carlo results. The efficiency estimates by the two parametric methods are highly correlated, whereas there are considerable differences between the DEA estimates and those from the parametric methods. This is also consistent with the Monte Carlo results. By comparing the alternative efficiency estimates in the two applications, it is found that there is less discrepancy among the three sets of efficiency estimates in the airline case than in the railway case. This can be partly attributed to the fact that there are fewer variations in the operating environments in the airline case than in the railway case. The simulation results in Part I provide some general guidelines regarding the relative merits of the three alternative methods under certain known conditions. The two applications of the three methods in Part II serve as examples of how these three methods can be applied to practical problems where no a priori knowledge of either the production technology nor the efficiency profile exists. They illustrate some of the problems that may be encountered in empirical applications.

description: As more people work from home or during travel, new opportunities and challenges arise around mobile office work. On one hand, people may work at flexible hours, independent of traffic limitations, but on the other hand, they may need to work at makeshift spaces, with less than optimal working conditions and decoupled from co-workers. Virtual Reality (VR) has the potential to change the way information workers work: it enables personal bespoke working environments even on the go and allows new collaboration approaches that can help mitigate the effects of physical distance. In this paper, we investigate opportunities and challenges for realizing a mobile VR offices environments and discuss implications from recent findings of mixing standard off-the-shelf equipment, such as tablets, laptops or desktops, with VR to enable effective, efficient, ergonomic, and rewarding mobile knowledge work. Further, we investigate the role of conceptual and physical spaces in a mobile VR office.

description: The charitable non-profit organization Literacy Nova Scotia (LNS) seeks to understand the state of literacy in the province. This necessitates reconceptualizing traditional understandings of literacy by accounting for emerging literacy types and considering literacy as practices rather than skills. A vast body of literature on literacy exists that seeks to measure and assess different types of literacy and their current state in various contexts. The objective of this scoping review is to survey these efforts and answer the overarching research question: What different forms of literacy exist and how have they been defined and measured in the literature? Peer reviewed and grey literature will be identified; our search will be limited to the English language, and literature published after the year 2014 for currency. It will consider peer-reviewed journal articles in Canada, but grey literature produced across the globe. This study will identify, appraise, and chart relevant existing literature. Key sources to be searched include the large bibliographic database Scopus and subject-specific databases in the field of Library and Information Science and Education. Grey literature will be retrieved using Google, by hand searching literature produced by adult education and literacy organizations, and through consultation with experts. A first round of screening will be conducted to identify literature that meets inclusion/exclusion criteria. A categorized list of different types of literacies identified from the first round of review will be produced and LNS will select types most relevant to their organizational objectives and focus. A second round of screening will take place based on these updated criteria. Data will be charted according to our data extraction form, and results will be collated and summarized. Bibliometric methods will be used to produce aggregated insights from the initial corpus of literature retrieved through our search strategy pre-screening. The authors kindly request any feedback on this protocol be provided to corresponding authors by email by February 15th, 2024.

It is shown that contrary to the standard result of the Lee--Oehme--Yang (LOY) theory, the diagonal matrix elements of this effective Hamiltonian can not be equal in a CPT invariant system. It is also shown that the scalar product of short, $|K_{S}>$, and long, $|K_{L}>$, living superpositions of neutral kaons can not be real when CPT symmetry is conserved in the system under considerations whereas within the LOY theory such a scalar product is real.

description: We provide a generic but physically clear discussion of the clustering properties of dark energy models. We explicitly show that in quintessence-type models the dark energy fluctuations, on scales smaller than the Hubble radius, are of the order of the perturbations to the Newtonian gravitational potential, hence necessarily small on cosmological scales. Moreover, comparable fluctuations are associated with different gauge choices. We also demonstrate that the often used homogeneous approximation is unrealistic, and that the so-called dark energy mutation is a trivial artifact of an effective, single fluid description. Finally, we discuss the particular case where the dark energy fluid is coupled to dark matter.

description: Radio halos are diffuse, extended sources of radio emission detected primarily in massive, merging galaxy clusters. In smaller and/or relaxed clusters, where no halos are detected, one can instead place upper limits to a possible radio emission. Detections and upper limits are both crucial to constrain theoretical models for the generation of radio halos. The upper limits are model dependent for radio interferometers and thus the process of obtaining these is tedious to perform manually. In this paper, we present a Python based tool to automate this process of estimating the upper limits. The tool allows users to create radio halos with defined parameters like physical size, redshift and brightness model. A family of radio halo models with a range of flux densities, decided based on the rms noise of the image, is then injected into the parent visibility file and imaged. The halo injected image and the original image are then compared to check for the radio halo detection using a threshold on the detected excess flux density. Injections separated by finer differences in the flux densities are carried out once the coarse range where the upper limit is likely to be located has been identified. The code recommends an upper limit and provides a range of images for manual inspection. The user may then decide on the upper limit. We discuss the advantages and limitations of this tool. A wider usage of this tool in the context of the ongoing and upcoming all sky surveys with the LOFAR and SKA is proposed with the aim of constraining the physics of radio halo formation. The tool is publicly available at https://github.com/lijotgeorge/UL-CALC.

description: Optically detected resonance spectroscopy has been used to investigate effects of weak random lateral potential energy fluctuations on internal transitions of charged magneto-excitons (trions) in quasi two-dimensional GaAs/AlGaAs quantum-well (QW) structures. Resonant changes in the ensemble photoluminescence induced by far-infrared radiation were studied as a function of magnetic field for samples having: 1) no growth interrupts (short range well-width fluctuations), and 2) intentional growth interrupts (long range monolayer well-width differences). Only bound-to-continuum internal transitions of the negatively charged trion are observed for samples of type 1. In contrast, a feature on the high field (low energy) side of electron cyclotron resonance is seen for samples of type 2 with well widths of 14.1 and 8.4 nm. This feature is attributed to a bound-to-bound transition of the spin-triplet with non-zero oscillator strength resulting from breaking of translational symmetry.

description: The optical design of the Einstein Telescope (ET) is based on a dual-recycled Michelson interferometer with Fabry-Perot cavities in the arms. ET will be constructed in a new infrastructure, allowing us to consider different technical implementations beyond the constraints of the current facilities. In this paper we investigate the feasibility of using beam-expander telescopes in the interferometer arms. We provide an example implementation that matches the optical layout as presented in the ET design update 2020. We further show that the beam-expander telescopes can be tuned to compensate for mode mismatches between the arm cavities and the rest of the interferometer.

description: Bulk metallic samples were synthesized from different binary powder mixtures consisting of elemental Cu, Co, and Fe using severe plastic deformation. Small particles of the ferromagnetic phase originate in the conductive Cu phase, either by incomplete dissolution or by segregation phenomena during the deformation process. These small particles are known to give rise to granular giant magnetoresistance. Taking advantage of the simple production process, it is possible to perform a systematic study on the influence of processing parameters and material compositions on the magneto-resistance. Furthermore, it is feasible to tune the magnetoresistive behavior as a function of the specimens chemical composition. It was found that specimens of low ferromagnetic content show an almost isotropic drop in resistance in a magnetic field. With increasing ferromagnetic content, percolating ferromagnetic phases cause an anisotropy of the magnetoresistance. By changing the parameters of the high pressure torsion process, i.e., sample size, deformation temperature, and strain rate, it is possible to tailor the magnitude of giant magneto-resistance. A decrease in room temperature resistivity of approx. 3.5% was found for a bulk specimen containing an approximately equiatomic fraction of Co and Cu.

Colpocephalum

description: Colpocephalum sp.
 Material examined: 1♂, Gyps bengalensis, Nepal.
 Measurements: HL 032 mm, HW: 0.49 mm; HI 0.65; MtW 0.42 mm; AL 0.94 mm; AW 0.53 mm; ToL 1.69 mm.
 Remarks. Two species of Colpocephalum: Col. satellitum (Eichler & Złotorzycka, 1963b) and Col. turbinatum Denny, 1842 are known from white-rumped vultures (Price et al. 2003: 317). Colpocephalum satellitum was described from Gyps bengalensis, but without adequate morphological features to identify this species, and we are unaware of any proper redescription. On the other hand, Colpocephalum turbinatum is known from many hosts and has been well redescribed by Price & Beer (1963). Considering that our single specimen is in poor condition, due to damage during re-mounting, we are unable to identify it to species.

description: This paper critically examines arguments against independence, a measure of group fairness also known as statistical parity and as demographic parity. In recent discussions of fairness in computer science, some have maintained that independence is not a suitable measure of group fairness. This position is at least partially based on two influential papers (Dwork et al., 2012, Hardt et al., 2016) that provide arguments against independence. We revisit these arguments, and we find that the case against independence is rather weak. We also give arguments in favor of independence, showing that it plays a distinctive role in considerations of fairness. Finally, we discuss how to balance different fairness considerations.

description: The capability of high-pressure torsion on the preparation of supersaturated solid solutions, consisting of Cu-14Fe (wt.%), is studied. From microstructural investigations a steady state is obtained with nanocrystalline grains. The as-deformed state is analyzed with atom probe tomography, revealing an enhanced solubility and the presence of Fe-rich particles. The DC-hysteresis loop shows suppressed long range interactions in the as-deformed state and evolves towards a typical bulk hysteresis loop when annealed at 500°C. AC-susceptometry measurements of the as-deformed state reveal the presence of a superparamagnetic blocking peak, as well as a magnetic frustrated phase, whereas the transition of the latter follows the Almeida-Thouless line, coinciding with the microstructural investigations by atom probe tomography. AC-susceptometry shows that the frustrated state vanishes for annealing at 250°C.

description: Existing spatial object recommendation algorithms generally treat objects identically when ranking them. However, spatial objects often cover different levels of spatial granularity and thereby are heterogeneous. For example, one user may prefer to be recommended a region (say Manhattan), while another user might prefer a venue (say a restaurant). Even for the same user, preferences can change at different stages of data exploration. In this paper, we study how to support top-k spatial object recommendations at varying levels of spatial granularity, enabling spatial objects at varying granularity, such as a city, suburb, or building, as a Point of Interest (POI). To solve this problem, we propose the use of a POI tree, which captures spatial containment relationships between POIs. We design a novel multi-task learning model called MPR (short for Multi-level POI Recommendation), where each task aims to return the top-k POIs at a certain spatial granularity level. Each task consists of two subtasks: (i) attribute-based representation learning; (ii) interaction-based representation learning. The first subtask learns the feature representations for both users and POIs, capturing attributes directly from their profiles. The second subtask incorporates user-POI interactions into the model. Additionally, MPR can provide insights into why certain recommendations are being made to a user based on three types of hints: user-aspect, POI-aspect, and interaction-aspect. We empirically validate our approach using two real-life datasets, and show promising performance improvements over several state-of-the-art methods.

description: The optical properties of Sn-doped Bi$_{1.1}$Sb$_{0.9}$Te$_{2}$S, the most bulk-insulating topological insulator thus far, have been examined at different temperatures over a broad frequency range. No Drude response is detected in the low-frequency range down to 30~cm$^{-1}$, corroborating the excellent bulk-insulating property of this material. Intriguingly, we observe a sharp peak at about 2\,200~cm$^{-1}$ in the optical conductivity at 5~K. Further quantitative analyses of the line shape and temperature dependence of this sharp peak, in combination with first-principles calculations, suggest that it corresponds to a van Hove singularity arising from Mexican-hat-shaped inverted bands. Such a van Hove singularity is a pivotal ingredient of various strongly correlated phases.

description: The "Polygons In Polygons" spatial relationship criterion is useful for analyzing how certain polygon features are fully contained within others. For instance, it can determine which parcels of land fall entirely within specific zoning areas or help identify properties located completely within protected regions, like nature reserves or conservation zones.

 

In cadastral analysis, it can highlight smaller land parcels (such as subdivided lots) that fall entirely within larger municipal or administrative boundaries.

 

In our case, we have a cadastral dataset that includes both land parcels and building polygons. The building polygons represent all the buildings in the village, while the land parcels are only for a portion of the area, designated for specific use.

 

Our goal is to compare the two layers to see which buildings fall inside the designated land parcels and which ones, are located outside.

description: We have observed the micro-quasar V4641 Sgr (SAX J1819.3-2525) at the time of flare during May 2002, using the Giant Metrewave Radio Telescope at low radio frequencies (244 and 610 MHz). This is the lowest frequency radio detection of the source. The source showed clear signature of spectral evolution from optically thick to thin state. We model the spectral evolution of the source to obtain some of the source parameters. Assuming the value of magnetic field strength to be in the range of 0.1 to 1 Gauss, we obtain the initial velocity of expansion of the jet to be in the range $\sim$ 0.45c to 0.25c. This is consistent with the known expansion velocities of the jet with other microquasars.

Complementarity versus coordinate transformations: mapping between pseudo-Hermiticity and weak pseudo-Hermiticity

description: \noindent We study the concept of the complementarity, introduced by Bagchi and Quesne in [Phys. Lett. A {\bf 301}, 173 (2002)], between pseudo-Hermiticity and weak pseudo-Hermiticity in a rigorous mathematical viewpoint of coordinate transformations when a system has a position-dependent mass. We first determine, under the modified-momentum, the generating functions identifying the complexified potentials $V_\pm(x)$ under both concepts of pseudo-Hermiticity $\widetildeη_+$ (resp. weak pseudo-Hermiticity $\widetildeη_-$). We show that the concept of complementarity can be understood and interpreted as a coordinate transformation through their respective generating functions. As consequence, a similarity transformation which implements coordinate transformations is obtained. We show that the similarity transformation is set up as fundamental relationship connecting both $\widetildeη_+$ and $\widetildeη_-$. A special factorization $η_+=η_-^\dagger η_-$ is discussed in the case of a constant mass and some Bäcklund transformations are derived.

description: We consider an arbitrary d_{1}\otimes d_{2}\otimes ... \otimes d_{N} composite quantum system and find necessary conditions for general m-party subsystem states to be the reduced states of a common N-party state. These conditions will lead to various monogamy inequalities for bipartite quantum entanglement and partial disorder in multipartite states. Our results are tightly connected with the measures of multipartite entanglement.

Electromagnetics from a quasistatic perspective

description: Quasistatics is introduced so that it fits smoothly into the standard textbook presentation of electrodynamics. The usual path from statics to general electrodynamics is rather short and surprisingly simple. A closer look reveals however that it is not without confusing issues as has been illustrated by many contributions to this Journal. Quasistatic theory is conceptually useful by providing an intermediate level in between statics and the full set of Maxwell's equations. Quasistatics is easier than general electrodynamics and in some ways more similar to statics. It is however, in terms of interesting physics and important applications, far richer than statics. Quasistatics is much used in electromagnetic modeling, an activity that today is possible on a PC and which also has great pedagogical potential. The use of electromagnetic simulations in teaching gives additional support for the importance of quasistatics. This activity may also motivate some change of focus in the presentation of basic electrodynamics.

description: We calculate the cosmic microwave background (CMB) angular trispectrum, spherical harmonic transform of the four-point correlation function, from primordial non-Gaussianity in primordial curvature perturbations characterized by a constant non-linear coupling parameter, $f_{\rm NL}$. We fully take into account the effect of the radiation transfer function, and thus provide the most accurate estimate of the signal-to-noise ratio of the angular trispectrum of CMB temperature anisotropy. We find that the predicted signal-to-noise ratio of the trispectrum summed up to a given $l$ is approximately a power-law, $(S/N)(

description: We propose the combination of forward shape derivatives and the use of an iterative inversion scheme for Bayesian optimization to find optimal designs of nanophotonic devices. This approach widens the range of applicability of Bayesian optmization to situations where a larger number of iterations is required and where derivative information is available. This was previously impractical because the computational efforts required to identify the next evaluation point in the parameter space became much larger than the actual evaluation of the objective function. We demonstrate an implementation of the method by optimizing a waveguide edge coupler.
Superconducting phase transition in inhomogeneous chains of superconducting islands

description: We study one dimensional chains of superconducting islands with a particular emphasis on the regime in which every second island is switched into its normal state, thus forming a superconductor-insulator-normal metal (S-I-N) repetition pattern. As is known since Giaever tunneling experiments, tunneling charge transport between a superconductor and a normal metal becomes exponentially suppressed, and zero-bias resistance diverges, as the temperature is reduced and the energy gap of the superconductor grows larger than the thermal energy. Here we demonstrate that this physical phenomenon strongly impacts transport properties of inhomogeneous superconductors made of weakly coupled islands with fluctuating values of the critical temperature. We observe a non-monotonous dependence of the chain resistance on both temperature and magnetic field, with a pronounced resistance peak at temperatures at which some but not all islands are superconducting. We explain this phenomenon by the inhomogeneity of the chains, in which neighboring superconducting islands have slightly different critical temperatures. We argue that the Giaever's resistance divergence can also occur in the zero-temperature limit. Such quantum transition can occur if the magnetic field is tuned such that it suppresses superconductivity in the islands with the weaker critical field, while the islands with stronger energy gap remain superconducting. In such a field, the system acts as a chain of S-I-N junctions.
