description: Novel sampling algorithms can significantly impact open questions in computational biology, most notably the in silico protein folding problem. By using computational methods, protein folding aims to find the three-dimensional structure of a protein chain given the sequence of its amino acid building blocks. The complexity of the problem strongly depends on the protein representation and its energy function. The more detailed the model, the more complex its corresponding energy function and the more challenge it sets for sampling algorithms. Kou, Zhou and Wong [math.ST/0507080] have introduced a novel sampling method, which could contribute significantly to the field of structural prediction.

description: In this study, we investigated the energy partition of four confined circular-ribbon flares (CRFs) near the solar disk center, which are observed simultaneously by SDO, GOES, and RHESSI. We calculated different energy components, including the radiative outputs in 1$-$8, 1$-$70, and 70$-$370 Å, total radiative loss, peak thermal energy derived from GOES and RHESSI, nonthermal energy in flare-accelerated electrons, and magnetic free energy before flares. It is found that the energy components increase systematically with the flare class, indicating that more energies are involved in larger flares. The magnetic free energies are larger than the nonthermal energies and radiative outputs of flares, which is consistent with the magnetic nature of flares. The ratio $\frac{E_{nth}}{E_{mag}}$ of the four flares, being 0.70$-$0.76, is considerably higher than that of eruptive flares. Hence, this ratio may serve as an important factor that discriminates confined and eruptive flares. The nonthermal energies are sufficient to provide the heating requirements including the peak thermal energy and radiative loss. Our findings impose constraint on theoretical models of confined CRFs and have potential implication for the space weather forecast.

description: The aim of the present thesis was the study of the institution of the local government. We examined the the necessity of the existence of government and its relationship with democracy. We examined theories concerning the natural law of self-government and the theory of the so-called right to self-government. Then we presented a brief history of local government in Greece but also in major countries abroad. Furthermore, we analyzed the European Charter of Local Self-Government and the Greek Constitution and how they give rise to the institution. We also examined the patented administrative independence as the European Charter and the Constitution , the manifestations of autonomy and independence. Finally we examined the institution of government oversight established in Greek law , the differences between the hierarchical control and coexistence under the administrative independence.
The origins of state security screening in Canada
Creators: name: Hannant, Larry
Publisher: name: University of British Columbia
Year: 2008

description: Describing Canada's security intelligence practice, historians have identified 1945as a watershed. In September of that year Igor Gouzenko defected from the embassy of the Soviet Union in Ottawa, carrying with him evidence that the Soviets operated an espionage ring in this country. According to historical canon, Gouzenko's defection and the investigations which resulted from it forced the Canadian government to initiate a security screening program for civil servants and armed forces personnel. This program was an attempt to discern the political opinions, behaviour and trustworthiness of people in positions of trust both inside the state and outside. This thesis rewrites the conventional history of state security screening in Canada. By reexamining existing evidence and making use of records uncovered through the Access to Information Act, this work demonstrates that security screening of civil servants, military personnel and naturalization applicants began in the years between the First and Second World Wars. Revising the point at which security screening began also forces a reevaluation of the motivation for security screening. Security screening was not launched to detect and neutralize foreign espionage agents. Rather, it was borne out of a deep fear of communists among the Canadian people. Concern about internal dissent, not about foreign spying, was responsible for this new security intelligence development. This work also reexamines the Canadian government's supervision of its primary security intelligence agency, the Royal Canadian Mounted Police. Contrary to the widely held view that the Canadian cabinet initiated and supervised the screening system, this thesis shows that the RCMP operated a program for at least fifteen years without political authorization and guidance. In doing so, it committed acts which can only be regarded as civil liberties violations. Nevertheless, abuses were relatively minor. One reason why they were was the dubious legality of the program. Carrying out a program which lacked political approval, the RCMP kept a tight rein on the security screening system, fearing a controversy which could be embarrassing and damaging to its own security intelligence capacity.

description: Coronal loop observations have existed for many decades yet the precise shape of these fundamental coronal structures is still widely debated since the discovery that they appear to undergo negligible expansion between their footpoints and apex. In this work a selection of eight EUV loops and their twenty-two sub-element strands are studied from the second successful flight of NASA's High resolution Coronal Imager (Hi-C 2.1). Four of the loops correspond to open fan structures with the other four considered to be magnetically closed loops. Width analysis is performed on the loops and their sub-resolution strands using our method of fitting multiple Gaussian profiles to cross-sectional intensity slices. It is found that whilst the magnetically closed loops and their sub-element strands do not expand along their observable length, open fan structures may expand an additional 150% of their initial width. Following recent work, the Pearson correlation coefficient between peak intensity and loop/strand width are found to be predominantly positively correlated for the loops (~88%) and their sub-element strands (~80%). These results align with the hypothesis of Klimchuk & DeForest that loops and - for the first time - their sub-element strands have approximately circular cross-sectional profiles.

description: We theoretically investigate the possibility of realizing a nonlinear all-optical diode by using the unique features of quasiperiodic 1D photonic crystals. The interplay between the intrinsic spatial asymmetry in odd-order Thue-Morse lattices and Kerr nonlinearity, combined with the unconventional field localization properties of this class of quasiperiodic sequences, gives rise to sharp resonances that can be used to give a polarization-insensitive, nonreciprocal propagation with a contrast close to unity for low optical intensities.

description: The main purpose of this study is to implement the appropriate Statistical Process Control (SPC) techniques to improve the water quality used to produce steam in the Utility plant. Different SPC tools have been identified and implemented in the project, process capability, Scatter Diagram, control chart, and variable charts (Individual and moving average). The Utility plant refers to a steam production plant that uses city water to produce steam. The plant sends the steam produced to heat the main campus core buildings and sanitization process at the medical core. In order to produce the steam a water treatment plant used before sending the water to the boilers, the water pH and TDS were measured by sensors and instruments to maintain an acceptable range in order to maintain a higher boilers efficiency and lower maintenance cost. This study concerns the use of statistical tools for the improvement of quality control. The measurements of pH (potential of hydrogen), and the total dissolved solids (TDS) in the water treatment facility, due to the importance of these particular and their potential fluctuations during the time interval. Results are presented by descriptive statistics, diagrams. Statistical process control techniques have been utilized for the evaluation of control limits regarding pH with a view to checking, analyzing, and finally improving the quality of the process

description: We model information traffic on scale-free networks by introducing the node queue length L proportional to the node degree and its delivering ability C proportional to L. The simulation gives the overall capacity of the traffic system, which is quantified by a phase transition from free flow to congestion. It is found that the maximal capacity of the system results from the case of the local routing coefficient ϕslightly larger than zero, and we provide an analysis for the optimal value of ϕ. In addition, we report for the first time the fundamental diagram of flow against density, in which hysteresis is found, and thus we can classify the traffic flow with four states: free flow, saturated flow, bistable, and jammed.

description: We consider 5D Einstein-Maxwell-dilaton (EMd) gravity in spacetimes with three commuting Killing vectors: one timelike and two spacelike Killing vectors, one of which is hypersurface-orthogonal. Assuming a special ansatz for the Maxwell field we show that the 2-dimensional reduced EMd equations are completely integrable. We also develop a solution generating method for explicit construction of exact EMd solutions from known exact solutions of 5D vacuum Einstein equations with considered symmetries. We derive explicitly the rotating dipole black ring solutions as a particular application of the solution generating method.

description: Hermitian theories play a major role in understanding the physics of most phenomena. It has been found only in the past decade that non-Hermiticity enables unprecedented effects such as exceptional points, spectral singularities and bulk Fermi arcs. Recent studies further show that non-Hermiticity can fundamentally change the topological band theory, leading to the non-Hermitian band topology and non-Hermitian skin effect, as confirmed in one-dimensional (1D) systems. However, in higher dimensions, these non-Hermitian effects remain unexplored in experiments. Here, we demonstrate the spin-polarized, higher-order non-Hermitian skin effect in two-dimensional (2D) acoustic metamaterials. Using a lattice of coupled whisper-gallery acoustic resonators, we realize a spinful 2D higher-order topological insulator (HOTI) where the spin-up and spin-down states are emulated by the anti-clockwise and clockwise modes, respectively. We find that the non-Hermiticity drives wave localizations toward opposite edge boundaries depending on the spin polarizations. More interestingly, for finite systems with both edge and corner boundaries, the higher-order non-Hermitian skin effect leads to wave localizations toward two corner boundaries for the bulk, edge and corner states in a spin-dependent manner. We further show that such a non-Hermitian skin effect enables rich wave manipulation through the loss configuration in each unit-cell. The reported spin-dependent, higher-order non-Hermitian skin effect reveals the interplay between higher-order topology and non-Hermiticity, which is further enriched by the spin degrees of freedom. This unveils a new horizon in the study of non-Hermitian physics and the design of non-Hermitian metamaterials.

description: We study Ruelle's type zeta and $L$-functions for a torsion free abelian group $\G$ of rank $\n\ge 2$ defined via an Euler product. It is shown that the imaginary axis is a natural boundary of this zeta function when $\n=2,4$ and 8, and in particular, such a zeta function has no determinant expression. Thus, conversely, expressions like Euler's product for the determinant of the Laplacians of the torus $\bR^{\n}/\G$ defined via zeta regularizations are investigated. Also, the limit behavior of an arithmetic function arising from the Ruelle type zeta function is observed.

 Description. The body is ovoid in shape and tapers gradually to the anterior end. The anterior end is truncated, and the posterior end is rounded. The cytostome is at the anterior end of the body and surrounded by long, fine cilia, forming the adoral ciliary zone. The cytoproct is at the posterior end of the body. The macronucleus and micronucleus are ovoid in shape, and the micronucleus adheres to various sides of the macronucleus. The position of macronucleus is not constant in the body. A concretion vacuole is present in the anterior one third of the body and below the adoral ciliary zone. A contractile vacuole is present in the posterior end of the body, near the cytoproct. The anterior two thirds of the body has somatic ciliary rows (Table 1, Figures 1a, 2, 3).
 Habitat, type host, and locality. The hindgut of Asian elephants (Elephas maximus) in Gaziantep Zoo, Gaziantep, Turkey. Etymology. The name minuta is given because of the very small dimensions of the ciliate. Type material. The specimens are held in the endocommensal ciliates of herbivores collection in the Department of Biology, Faculty of Sciences and Arts, Kastamonu University, Kastamonu, Turkey. Holotype and paratypes are on the slide numbered as EIC-3.
 Remarks. B. minuta n. sp. is distinguishable from other Buetschlia species by its somatic ciliary rows at the anterior two thirds of the body.
  Infraciliature of B. minuta n. sp.  An adoral polybrachykinety, in which each kinety extends obliquely to the longitudinal body axis, completely encircles the cytostome. Paralabial kineties are four in number and overlie slightly obliquely the concretion vacuole immediately posterior to the adoral polybrachykinety. Paralabial kineties have short, modified cilia, and the number of cilia varies from two to seven. The thin pellicular fold is between paralabial kineties. Somatic kineties are three to four in number in one part of the body, and each somatic kinety has five to eight cilia (Figures 1b, 2, 3).

description: Predicting tropical cyclone (TC) rapid intensification (RI) is an important yet challenging task in current operational forecast due to our incomplete understanding of TC nonlinear processes. This study examines the variability of RI onset, including the probability of RI occurrence and the timing of RI onset, using a low-order stochastic model for TC development. Defining RI onset time as the first hitting time in the model for a given subset in the TC-scale state space, we quantify the probability of the occurrence of RI onset and the distribution of the timing of RI onset for a range of initial conditions and model parameters. Based on asymptotic analysis for stochastic differential equations, our results show that RI onset occurs later, along with a larger variance of RI onset timing, for weaker vortex initial condition and stronger noise amplitude. In the small noise limit, RI onset probability approaches one and the RI onset timing has less uncertainty (i.e., a smaller variance), consistent with observation of TC development under idealized environment. Our theoretical results are verified against Monte-Carlo simulations and compared with explicit results for a general 1-dimensional system, thus providing new insights into the variability of RI onset and helping better quantify the uncertainties of RI variability for practical applications.

description: Offsite manufacturing (OSM) has been recently highlighted as contributing to increase productivity and to tackle labour shortages in the housing sector. Whilst a range of OSM building technologies are already used for the construction of homes, few evidence-based studies report on the evaluation of associated performances beyond the circumstantial conditions of project delivery. A comparative analysis of housing developments using different OSM solutions was carried out as part of a live pilot project in Hertfordshire, UK, to gather tangible data on the performances of offsite construction (OC) in housebuilding projects on small infill sites that may not be the prime focus of the industry. A dedicated evaluation model was described as per to highlight the impacts of varied building technologies integrating offsite manufacture (OSM) processes on homes delivery performances in the low-rise housing sub-sector. Secondary data from case study exemplars was extracted to test the model and speculate on associated contributions to knowledge. Delays in the progression of the project suggested inherent challenges in working with partners at a local level on the implementation of innovative construction methods for housing that might present complex and intricate contexts as well as a lack of economy of scale. The increase of risk and lateness of executive choices resulting from the adoption of OSM highlighted both the relative immaturity of the OSM market and the need to simplify procurement through dedicated business models.

description: We present a study of the influence of magnetic field strength and morphology in Type Ia Supernovae and their late-time light curves and spectra. In order to both capture self-consistent magnetic field topologies as well evolve our models to late times, a two stage approach is taken. We study the early deflagration phase (1s) using a variety of magnetic field strengths, and find that the topology of the field is set by the burning, independent of the initial strength. We study late time (~1000 days) light curves and spectra with a variety of magnetic field topologies, and infer magnetic field strengths from observed supernovae. Lower limits are found to be 106G. This is determined by the escape, or lack thereof, of positrons that are tied to the magnetic field. The first stage employs 3d MHD and a local burning approximation, and uses the code Enzo. The second stage employs a hybrid approach, with 3D radiation and positron transport, and spherical hydrodynamics. The second stage uses the code HYDRA. In our models, magnetic field amplification remains small during the early deflagration phase. Late-time spectra bear the imprint of both magnetic field strength and morphology. Implications for alternative explosion scenarios are discussed.

description: Written language is an integral part of the curricula in Secondary Education. In fact, written expression is the primary means which the students use to prove their knowledge and communicate their thoughts, beliefs and emotions. High school students are expected to narrate, inform and argue, while written examinations are a prerequisite for their transition to the next grade or level. Unfortunately, the students with Attention-Deficit Hyperactivity Disorder (ADHD) and/or Learning Disabilities (LD) struggle to respond to these requirements, indicating low levels of self-regulation, which affects their writing. The present study aims at exploring the impact of self-regulation on secondary school students with ADHD, who have difficulty in writing. The Greek reality is also discussed in relation to diagnostic criteria of ADHD and LD, and what is expected from the students of secondary education. The strategies and interventions suggested in literature are investigated under the scope of self-determination, motivation and self-regulation. Self-regulated learning is explored as a factor which can help high school students improve their writing.
Passing the buck: federalism and Canadian environmental policy
Creators: name: Harrison, Kathryn J.
Publisher: name: University of British Columbia
Year: 2008

description: This thesis examines how the current division of federal and provincial responsibilities for environmental policy in Canada evolved, and the implications of that arrangement for protection of the environment. At a theoretical level, the example of environmental protection is used to explore the relationship between federalism and public policy more generally. It is accepted wisdom that governments seek both to claim credit and avoid blame. However, to date, students of Canadian federalism have been much more attentive to the dynamics of intergovernmental credit claiming than to opportunities for intergovernmental blame avoidance. A central argument of this thesis is that the implications of federalism for public policy are very different when both levels of government are eager to assume responsibility for a particular policy than when one or both are content to vacate the field. It is argued that because environmental protection typically involves diffuse benefits and concentrated costs, it offers few political benefits and significant political costs. Thus the case of environmental protection is used to explore the implications of policy inaction within the federal system. The thesis presents a study of the evolution of the federal government’s role in environmental protection and of federal-provincial relations concerning the environment between 1968 and1992. The exclusive focus of the thesis is the federal government’s role in "federal Canada," that is, within the provinces, rather than the Northern territories. It is argued that the federal government has taken advantage of overlapping jurisdiction to shirk its responsibility for environmental protection for most of the last two decades. In light of federal deference to the provinces, federal-provincial relations concerning the environment have been relatively cooperative, with the important exception of two brief periods of heightened salience of environmental issues, during which both levels of government were more inclined to adopt a broad view of their jurisdiction. A case study of federal and provincial regulation of pulp mill effluents offers considerable evidence of provincial reluctance to strengthen environmental standards for fear of placing local industry at a competitive disadvantage. Scholars troubled by the environmental implications of interprovincial economic competition typically look to the federal government to establish national standards. However, it is argued that many have underestimated the political obstacles to such a federal response.

description: We investigate coarse-grained models of suspended self-thermophoretic microswimmers. Upon heating, the Janus spheres, with hemispheres made of different materials, induce a heterogeneous local solvent temperature that causes the self-phoretic particle propulsion. Starting from atomistic molecular dynamics simulations, we verify the coarse-grained description of the fluid in terms of a local molecular temperature field, and its role for the particle's thermophoretic self-propulsion and hot Brownian motion. The latter is governed by effective nonequilibrium temperatures, which are measured from simulations by confining the particle position and orientation. They are theoretically shown to remain relevant for any further spatial coarse-graining towards a hydrodynamic description of the entire suspension as a homogeneous complex fluid.

description: The quasielastic production cross sections and polarizations of the hyperons induced by ${\barν}_μ$ on the free nucleon as well as from $^{40}$Ar in the sub-GeV energy region has been reviewed [1-5]. The effects of the second class currents in the axial vector sector with and without T-invariance as well as the effect of SU(3) symmetry breaking are also studied. We find that the cross sections and the various polarization components can effectively be used to determine the axial vector transition form factors in the strangeness sector and to test the validity of various symmetries of the weak hadronic currents like G-invariance, T-invariance and SU(3) symmetry. These hyperons decay dominantly into pions giving an additional contribution to the weak pion production induced by the antineutrinos. In the case of nuclear targets like $^{40}$Ar, this contribution is shown to be significant when compared with the pion production by the $Δ$ excitations in the energy range of $E_{\barν_μ} \le 0.7$ GeV [1]. This study could be useful for the DUNE experiment where argon will be used as the target material and the electronic imaging of particles is possible and the particle tracks can be identified.

description: Impact evaluation in public engagement necessarily requires measuring change. However, this is extremely challenging for drop-in activities due to their very nature. We present a novel method of impact evaluation which integrates graffiti walls into the experience both before and after the main drop-in activity. The activity in question was a soundscape exhibit, where young families experienced the usually inaudible sounds of near-Earth space in an immersive and accessible way. We apply two analysis techniques to the captured before and after data - quantitative linguistics and thematic analysis. These analyses reveal significant changes in participants' responses after the activity compared to before, namely an increased diversity in language used to describe space and altered conceptions of what space is like. The results demonstrate that the soundscape was surprisingly effective at innately communicating key aspects of the underlying science simply through the act of listening. The impacts also highlight the power of sonification in stimulating public engagement, which, through reflection, can lead to altered associations, perceptions, and understanding. Therefore, we show that this novel approach to drop-in activity evaluation, using graffiti walls both before and after the activity and applying rigorous analysis to this data, has the power to capture change and, thus, have a short-term impact. We suggest that commonly used evaluation tools suitable for drop-in activities, such as graffiti walls, should be integrated both before and after the main activity in general, rather than only using them afterwards as is typically the case.

urn:lsid:zoobank.org:act: 46B14115-7EA5-4338-AAAF-A17DC250AC53
 Description. The body is ovoid in shape and tapers gradually to the anterior end. The anterior end is truncated, and the posterior end is rounded. The cytostome is at the anterior end of the body and surrounded by long, fine cilia, forming the adoral ciliary zone. The cytoproct is at the posterior end of the body. The macronucleus and micronucleus are ovoid in shape, and the micronucleus adheres to various sides of the macronucleus. The position of the macronucleus is not constant in the body. A concretion vacuole is present in the anterior one third of the body and below the adoral ciliary zone. A contractile vacuole is present in the posterior end of the body, near the cytoproct. The entire body has unevenly distributed somatic cilia (Table 2, Figures 4a, 5, 6).
 Habitat, type host, and locality. The hindgut of Asian elephants (Elephas maximus) in Gaziantep Zoo, Gaziantep, Turkey. Etymology. The name cirrata is given because of the unevenly distributed somatic cilia.
 Type material. The specimens are held in the endocommensal ciliates of herbivores collection in the Department of Biology, Faculty of Sciences and Arts, Kastamonu University, Kastamonu, Turkey. Holotype and paratypes are on the slide numbered as EIC-4.
 Remarks. B. cirrata n. sp. is distinguishable from other Buetschlia species by its unevenly distributed somatic cilia.
  Infraciliature of B. cirrata n. sp.  An adoral polybrachykinety, in which each kinety extends obliquely to the longitudinal body axis, completely encircles the cytostome. Paralabial kineties are four in number, overlie slightly obliquely the concretion vacuole just posterior to the adoral polybrachykinety. Paralabial kineties have short, modified cilia, and the number of cilia varies from two to seven. The thin pellicular fold is between paralabial kineties. The number of pellicular folds is four. Somatic kineties are unevenly distributed over the body (Figures 4b, 5, 6).

description: Όπως προέκυψε από την εξέταση του ζητήματος των προϋποθέσεων καταρχήν άσκησης του δικαιώματος της καταγγελίας της σύμβασης έργου από τον εργοδότη, όπως προβλέπεται η άσκηση του δικαιώματος αυτού στη διάταξη του άρθρου 700 ΑΚ, θα πρέπει να επισημανθεί ότι η καταγγελία της σύμβασης έργου, αποτελεί ένα δικαιολογημένο λόγο λήξης αυτής για τους λόγους που αναπτύχθηκαν. Περαιτέρω, όπως αναφέρθηκε, βασική συνέπεια της άσκησης της καταγγελίας, αποτελεί η ex nunc λύση της σύμβασης, με αποτέλεσμα να επιβάλλεται στον μεν εργολάβο να παραδώσει το έργο στην κατάσταση στην οποία βρίσκεται κατά την καταγγελία, στον δε εργοδότη να καταβάλει τη συμφωνημένη αμοιβή από την οποία αφαιρείται, η δαπάνη που εξοικονόμησε ο εργολάβος, ό, τι ωφελήθηκε από άλλη εργασία του ή παρέλειψε με δόλο να ωφεληθεί. Πέρα από τις προϋποθέσεις και τις συνέπειες άσκησης του δικαιώματος της καταγγελίας της σύμβασης έργου από τον εργοδότη, σκόπιμο κρίθηκε να εξεταστεί περαιτέρω και η σχέση του διαπλαστικού αυτού δικαιώματος με τα άλλα δικαιώματα που τίθενται στη διάθεση του εργοδότη και τα οποία προβλέπονται τόσο στις διατάξεις που ρυθμίζουν τη σύμβασης έργου όσο και στις γενικές διατάξεις του ενοχικού δικαίου. Ειδικότερα, ιδιαίτερο ενδιαφέρον παρουσιάζει η σχέση του δικαιώματος άσκησης καταγγελίας της σύμβασης με την άσκηση του επίσης διαπλαστικού δικαιώματος της υπαναχώρησης από τη σύμβαση έργου και ειδικότερα η άσκηση της υπαναχώρησης του άρθρου 686 ΑΚ .
description: As a result from the examination of the issue of the requirements for the exercise of the employer’s right to terminate the works contract in principal, as the exercise of this right is provided for in section 700 of the Civil Code, it must be noted that the termination of works contract, constitutes a justified reason for its termination for the reasons that has been developed. Furthermore, as it has been mentioned, contract’s termination’s basic consequence is the “ex nunc” termination of the contract, with the result that the contractor is obligated to deliver the project in the current condition at the time of termination and on the other hand the employer is obligated to pay the agreed fee minus the costs the contractor has saved, whatever he acquired as benefit from other activities or deliberately failed to acquire. Beyond the requirements and the consequences of the employer’s exercise of the right to terminate the works contract, it has been considered appropriate to examine furthermore the correlation between this formative right with other rights placed at employer’s disposal, as they are provided for by the provisions which regulate the works contract itself and by the general sections of the law of obligations as well. Specifically, it comes with great interest the correlation between the right of contract termination with the, as well formative, right of withdrawal from the contract and especially with the exercise of withdrawal as it is provided for in section 686 of the Civil Code.

description: We present measurements of the temperature-dependent momentum distribution of a trapped Fermi gas consisting of $^{40}$K in the BCS-BEC crossover regime. Accompanying theoretical results based upon a simple mean-field ground state are compared to the experimental data. Non-monotonic effects associated with temperature, $T$, arise from the competition between thermal broadening and a narrowing of the distribution induced by the decrease in the excitation gap $Δ(T)$ with increasing $T$.

description: Inspired by the work of Kamenev and Kohn, we present a general discussion of the two-terminal dc conductance of molecular devices within the framework of Time Dependent Current-Density Functional Theory. We derive a formally exact expression for the adiabatic conductance and we discuss the dynamical corrections. For junctions made of long molecular chains that can be either metallic or insulating, we derive the exact asymptotic behavior of the adiabatic conductance as a function of the chain's length. Our results follow from the analytic structure of the bands of a periodic molecular chain and a compact expression for the Green's functions. In the case of an insulating chain, not only do we obtain the exponentially decaying factors, but also the corresponding amplitudes, which depend very sensitively on the electronic properties of the contacts. We illustrate the theory by a numerical study of a simple insulating structure connected to two metallic jellium leads.
