description: Four-wave mixing (FWM) in optical fibre is a leading technique for generating high-quality photon pairs. We report the generation of photon pairs by spontaneous FWM in photonic crystal fibre pumped by a 1.5 GHz repetition-rate vertical-external-cavity surface-emitting laser (VECSEL). The photon pairs exhibit high count rates and a coincidence-to-accidental ratio of over 80. The VECSEL's high repetition-rate, high average power, tunability, and small footprint make this an attractive source for quantum key distribution and photonic quantum-state engineering.

Enhanced oil recovery
Unconventional shale

description: Shale oil production from plays such as the Bakken and Eagle Ford, driven by advances in horizontal well drilling and hydraulic fracturing technology, has helped improve US domestic oil production. However, due to the low permeability of shale oil reservoirs, primary depletion only produces 5 – 10% of the original oil in place and there is an enormous potential for improved recovery. Chemical and gas huff-and-puff methods have been piloted with varying degrees of success, but no breakthrough recovery method has been discovered. In this study, we examined improved oil recovery from shale reservoirs by thermal stimulation, consisting of primary depletion (early in a well’s life), followed by conversion of the well to a heat injector to elevate reservoir temperature, and finally a secondary depletion. A 2D black oil, thermal, reactive transport simulator was developed to test the viability of the proposed method and then CMG STARS, a more advanced compositional/thermal simulator, was used to investigate the mechanisms involved, as well as key parameters affecting recovery during thermal stimulation. We found that 1000 days of thermal stimulation with a 700 °F heater has the potential to increase economical oil recovery from about 7% to more than 11.5%, with potential for even greater recovery if heat injection time and temperature are optimized, as well as if heat is injected while producing oil from an adjacent well. Thermal pressurization of oil is the primary mechanism for the improved recovery. Kerogen decomposition into oil and gas results in a significant increase of hydrocarbons in place but is only a minor contribution to the additional recovery because production is limited by a lack of flow capacity. Furthermore, a two-fold increase in permeability is observed as a result of kerogen decomposition, but its contribution to recovery is also minor because the heated region is not well connected with the fractured region. The heating scheme may be improved in the future to better connect the heated region with the fractured region.

description: We present a model of neutrino mixing based on the flavour group $Δ(27)$ in order to account for the observation of a non-zero reactor mixing angle ($θ_{13}$). The model provides a common flavour structure for the charged-lepton and the neutrino sectors, giving their mass matrices a `circulant-plus-diagonal' form. Mass matrices of this form readily lead to mixing patterns with realistic deviations from tribimaximal mixing, including non-zero $θ_{13}$. With the parameters constrained by existing measurements, our model predicts an inverted neutrino mass hierarchy. We obtain two distinct sets of solutions in which the atmospheric mixing angle lies in the first and the second octants. The first (second) octant solution predicts the lightest neutrino mass, $m_3 \sim 29~\text{meV}$ ($m_3 \sim 65~\text{meV}$) and the $CP$ phase, $δ_{CP} \sim -\fracπ{4}$ ($δ_{CP} \sim \fracπ{2}$), offering the possibility of large observable $CP$ violating effects in future experiments.

description: Based on the complexity equals action (CA) and complexity equals volume (CV) conjectures, we investigate the holographic complexity of a slowly accelerating Kerr-AdS black hole in the bulk Einstein gravity theory which is dual to holographic states with rotation and conical deficits in the boundary quantum system. Upon obtaining an implicit form of the Wheeler-DeWitt patch, we evaluate the action and show that the growth rate of the CA complexity violates volume-scaling formulation in large black hole limit due to the non-trivial contribution from the not-too-small acceleration of the black hole. Moreover, in an ensemble with fixed entropy, pressure, and angular momentum, we also find that complexity of formation decreases with both the average and difference of the conical deficits on the poles when the black hole is close to the static limit but increases with the deficits when the black hole is close to the extremal regime.

description: Modified oligonucleotides with redox-active functional groups could emerge as attractive tools for sensor development. In principle, changes in oligonucleotide hybridization or conformation may be read out as a change in an electrochemical signal. Monitoring this signal might allow for a direct interface between biology and electronics. This dissertation describes efforts devoted to creating redox active oligonucleotide derivatives designed to allow these application goals to be pursued. The focus is primarily on the synthesis, characterization, and application of oligonucleotides bearing on of two electroactive moieties, namely ferrocene and methylene blue. Chapter 1 provides a brief overview of electrochemically modified oligonucleotides and is designed to provide an historical perspective. Synthetic methodology, fabrication of electrode system, and current applications are introduced. Chapter 2 describes the synthesis of a ferrocene-modified oligonucleotide and its use as a multiplexing signal probe. Included in this chapter are syntheses of a ferrocene subunit bearing alkynes, as well as modified nucleoside phosphoramidites and the oligonucleotide syntheses they permit. A synopsis of electrochemical studies are also provided. Chapter 3 describes a ratiometric electrochemical DNA sensor (a so-called E-Sensor) based on the ferrocene-modified oligonucleotide described in Chapter 2 and its used in the detection of specific genes with greatly improved reproducibility. Oligonucleotide syntheses achieved through enzyme ligation, the fabrication of an E-sensor, and the results of electrochemical assays are provided in this chapter. Chapter 4 describes the design and fabrication of possible wearable devices with the modified electrochemically active oligonucleotides toward real diagnostic applications. This work is being done in collaboration with Dr. Nanshu Lu’s group in the Dept. of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin. Chapter 5 the details the synthetic procedures, provides characterization of all new products, and contains electrochemical analytical data discussed in this dissertation.

description: Reversible circuits form the backbone for many promising emerging technologies such as quantum computing, low power/adiabatic design, encoder/decoder devices, and several other applications. In the recent years, the scalable synthesis of such circuits has gained significant attention. In this work, we present the SyReC Synthesizer, a synthesis tool for reversible circuits based on the hardware description language SyReC. SyReC allows to describe reversible functionality at a high level of abstraction. The provided SyReC Synthesizer then realizes this functionality in a push-button fashion. Corresponding options allow for a trade-off between the number of needed circuit signals/lines (relevant, e.g., for quantum computing in which every circuit line corresponds to a qubit) and the respectively needed gates (corresponding to the circuit's costs). Furthermore, the tool allows to simulate the resulting circuit as well as to determine the gate costs of it. The SyReC Synthesizer is available as an open-source software package at https://github.com/cda-tum/syrec as part of the Munich Quantum Toolkit (MQT).

description: Biofilms are communities of sessile microbes that are phenotypically distinct from their genetically-identical, free-swimming counterparts. Biofilms initiate when bacteria attach to a solid surface, as this attachment triggers intracellular signaling to change gene expression of individual bacteria from the planktonic to the biofilm phenotype. However the initial cues leading allowing bacteria to sense a surface, as well as the role of spatial structure in biofilm development, are not well known. This dissertation has two main parts, the first presenting a method for growing biofilms from initiating cells whose positions are controlled with single-cell precision using laser trapping. Biofilm infections are notoriously intractable, in part due to changes in the bacterial phenotype that result from spatial structure. Understanding the role of structure in biofilm development requires methods to control the spatial structure of biofilms. The native growth, motility, and surface adhesion of positioned microbes are preserved, as we show for model organisms Pseudomonas aeruginosa and Staphylococcus aureus. We demonstrate that laser-trapping and placing bacteria on surfaces can reveal the e↵ects of spatial structure on bacterial growth in early biofilm development. In the second part we show that mechanical shear acts as a cue for surface adhesion in P. aeruginosa. For P. aeruginosa, it has long been known that intracellular levels of the signaling molecule cyclic-di-GMP increase upon surface adhesion and that increased cyclic-di-GMP is required to begin biofilm development. The magnitude of the shear force, and thereby the corresponding activation of cyclic-di-GMP signaling, can be adjusted both by varying the strength of the adhesion that binds bacteria to the surface and by varying the rate of fluid flow over surface-bound bacteria. We show that the envelope protein PilY1 and functional Type IV pili are required mechanosensory elements. Finally, we propose an analytic model that accounts for the feedback between mechanosensors, cyclic-di-GMP signaling, and production of adhesive polysaccharides, describing our data

description: This thesis presents advanced design techniques for successive approximation register (SAR) analog-to-digital converters (ADCs), continuous-time ∆Σ ADCs, and single-slope (SS) ADCs in nano-scale CMOS technologies. (1) In high-speed SAR ADCs, metastability of the comparator limits the performance, which even results in the sparkle code errors. Proposed background calibration utilizing the comparator decision time detector removes the metastability-induced sparkle code errors by controlling the metastability detection window. At the same time, 1-bit resolution increase is gained from the proposed technique, which results in the fewer comparison cycles. Along with the relaxed requirement on the comparator, this cycle reduction helps to achieve the good power efficiency in high-speed SAR design. A prototype ADC in 40nm CMOS achieves 35.3dB SNDR and consumes 0.81mW while sampling at 700MS/s. (2) In the proposed continuous-time ∆Σ ADCs, conventional power-hungry opamp is replaced by voltage controlled oscillators (VCOs) that perform the data conversion in the phase domain instead of the voltage domain. In contrary to the opamp which is difficult to achieve good performance in the advanced CMOS process, VCOs have many advantages in the phase domain. To solve the nonlinear gain of VCOs, dual VCO-based integrator is used to suppress the dominant second-order distortion. To address the distortion from the DAC, a novel DAC calibration technique that both digitally senses and removes DAC mismatch errors is proposed. It has low hardware complexity by taking advantage of the intrinsic clocked level averaging (CLA) capability of dual-VCO-based integrator. It ensures high linearity regardless of the VCO center frequency. By lowering the VCO center frequency, power consumption is reduced. A prototype ADC designed in 130nm occupies an area of only 0.04mm² . It achieves 71dB SNDR over 1.7MHz bandwidth (BW) while sampling at 250MS/s and consuming only 0.9mW from a 1.2V power supply. The corresponding figure-of-merit (FOM) is 98 fJ/conversion-step. (3) A SS ADC has advantages of high linearity and a simple architecture. Thus, it is well suited for the column-parallel architecture for the CMOS image sensors. However, conversion speed is severely limited in high-bit resolution since more than 2 [superscript N] cycles are required for a N-bit resolution. To tackle this limitation, a two-step approach becomes popular. In this thesis, a two-step SAR/SS architecture is presented. In addition to reducing the conversion time, analog correlated double sampling (CDS) can cancel kT/C noise, which enables capacitor area reduction. A prototype ADC in 180nm CMOS occupies only 9.3µm x 830µm. It achieves 60.5dB SNR after CDS while sampling at 256kHz and consuming 91µW

description: The dynamics of two component coupled Airy beams is investigated. In the linear propagation regime a complete analytic solution describes breather like propagation of the two components featuring non-diffracting self-accelerating Airy behavior. The superposition of two beams with different input properties opens the possibility to design more complex non-diffracting propagation scenarios. In the strongly nonlinear regime the dynamics remains qualitatively robust as is revealed by direct numerical simulations. Due to the Kerr effect the two beams emit solitonic breathers, whose coupling period is compatible with the remaining Airy-like beams. The results of this study are relevant for the description of photonic and plasmonic beams propagating in coupled planar waveguides as well as for birefrigent or multi-wavelengths beams.

description: Die akute Sigmadivertikulitis ist häufig und wird meistens über eine teure und strahlenintensive abdominelle Computertomographie (CT) diagnostiziert. Diese Studie zeigt, dass bei unkomplizierten Fällen die alleinige Sonographie ausreichen ist, und eine zusätzliche CT den selten Behandlungsplan ändert. Eine routinemäßige CT ist daher unnötig. Sie sollte nur bei Komplikationen oder unklarer Sonographie durchgeführt werden. Dies galt für 45,5% der Patienten. Zufallsbefunde wurden in 10,6% der Fälle entdeckt, aber das Fehlen der CT hätte kein wesentliches Risiko dargestellt.

description: Software implements a significant proportion of functionality in factory automation. Thus, efficient development and the reuse of software parts, so-called units, enhance competitiveness. Thereby, complex control software units are more difficult to understand, leading to increased development, testing and maintenance costs. However, measuring complexity is challenging due to many different, subjective views on the topic. This paper compares different complexity definitions from literature and considers with a qualitative questionnaire study the complexity perception of domain experts, who confirm the importance of objective measures to compare complexity. The paper proposes a set of metrics that measure various classes of software complexity to identify the most complex software units as a prerequisite for refactoring. The metrics include complexity caused by size, data structure, control flow, information flow and lexical structure. Unlike most literature approaches, the metrics are compliant with graphical and textual languages from the IEC 61131-3 standard. Further, a concept for interpreting the metric results is presented. A comprehensive evaluation with industrial software from two German plant manufacturers validates the metrics' suitability to measure complexity.

description: Dipolariton is a voltage controlled mixture of direct and indirect excitons in asymmetric double quantum wells coupled by resonant carrier tunneling, and a microcavity photon. We calculate the voltage dependence of the spin-singlet and spin-triplet interaction parameters $α_{1}$ and $α_{2}$. Both parameters can reach values one order of magnitude larger than that of exciton-polaritons thanks to the strong interaction between indirect excitons. We show that the variation of the indirect exciton fraction of the dipolaritons induces a changes of sign of $α_{2}$ increasing voltage: the interaction passes from attractive to repulsive. For large enough voltage $α_{2}$ becomes larger than $α_{1}$ which in principle can lead to the formation of a circularly polarised dipolariton condensate. We propose an application of the $α_{2}$ dependence to a voltage-controlled dipolaritonic optical parametric oscillator. The change of sign of $α_{2}$ allows an on-site control of the linear polarization degree of the optical signal and its on-demand inversion.

description: The expected sensitivity of cluster SZ number counts to neutrino mass in the sub-eV range is assessed. We find that from the ongoing {\it Planck}/SZ measurements the (total) neutrino mass can be determined at a (1-sigma) precision of 0.06 eV, if the mass is in the range 0.1-0.3 eV, and the survey detection limit is set at the 5-sigma significance level. The mass uncertainty is predicted to be lower by a factor ~2/3, if a similar survey is conducted by a cosmic-variance-limited experiment, a level comparable to that projected if CMB lensing extraction is accomplished with the same experiment. At present, the main uncertainty in modeling cluster statistical measures reflects the difficulty in determining the mass function at the high-mass end.

description: We study the effect of baryons on the cosmic web -- halos, filaments, walls, and voids. To do so, we apply a modified version of NEXUS, a cosmic web morphological analysis algorithm, to the IllustrisTNG simulations. We find that halos lose more than $10\%$ of their mass due to baryons, mostly to filaments and a small portion to walls and voids. However, the mass transfer does not significantly shift the boundaries of structures, leaving the volume fractions of the cosmic structures largely unaffected. We quantify the effects of baryonic feedback on the power spectrum and the probability density function (PDF) of the density field for individual cosmic structures. For the power spectrum, most suppression due to feedback can be accounted for by including $M\ge10^{12}~M_\odot/h$ halos, without considering other cosmic structures. However, when examining the PDF of the density field, we find nearly $100\%$ suppression of the emptiest regions and $10\%$-level effects (boost or suppression) in the remaining regions of filaments, walls, and voids. Our results indicate the importance of modeling the effects of baryons in the whole cosmic web, not just halos, for cosmological analysis beyond two-point statistics or field-based inferences.

description: Nel corso di questo lavoro proveremo a decostruire il lessico del diritto allo scopo di metterlo alla prova rispetto alle sfide che si affacciano nello scenario globale. L’analisi che cercheremo di sviluppare muove dalla necessità di ripensare alcune delle categorie elaborate dalla rappresentazione moderna, dal momento che nuove forme di potere si delineano sulla scena, frammentando quell’immagine nitida e lineare generata dal modello di Westfalia. Da un lato, infatti, il processo di costituzionalizzazione dei diritti ha reso problematico il rapporto fra diritto e morale, facendo vacillare la distinzione kelseniana fra Sein e Sollen, dall’altro, l’implosione degli spazi, l’enuclearsi dei rapporti economici dai contesti giuridici statali e territoriali, i processi di disseminazione e disarticolazione dei luoghi di produzione del diritto, che rappresentano gli aspetti fenomenici della globalizzazione, incrinando la sintesi politica offerta dallo Stato moderno, hanno contribuito a sottoporre a trazione profonda i costrutti formali della scienza giuridica. Lo spazio globale, infatti, è animato da soggetti che manifestano una tendenza all’attivismo e allo strumentalismo verso il diritto: law firms, transnational corporations, non governamental organizations, affidandosi all’autogovernamentalità e all’autoimprenditorialità, producono regole o pseudo-regole affini alle loro esigenze e capaci di diffondersi oltre ogni confine territoriale. La governance emergente elabora incessantemente nuove figure giuridiche, cornici normative aperte e flessibile, pronte a tradurre sempre nuovi contenuti. È questo un diritto che predispone dispositivi giuridici duttili, mutevoli, elastici che si prestano ad essere riempiti di volta in volta di contenuti specifici. Il significato tradizionale dei costrutti giuridici esce svilito dal confronto con una realtà di diritti e poteri molto più complessa, più frammentata, più disarticolata di quella espressa dal modello ordinamentale di Westafalia. Certamente, come è stato osservato, nessuna delle categorie giuridiche con cui si esprime il diritto può essere ritenuta superata, né la norma, né la decisione, né la sovranità, ma nessuna di esse oggi riveste più il significato che la scienza giuridica, consolidandosi nel tempo, le aveva conferito. Sempre più spesso, infatti, si sente parlare di decodificazione, degiuridificazione, deregulation, per descrivere l’incapacità dello strumento giuridico di tradurre il nuovo assetto dei poteri sociali.[a cura dell'autore]

description: Abe Shinzō served as Prime Minister of Japan from September 2006 to September 2007, and again from December 2012 to September 2012. His first term made him one of the shortest-serving Japanese prime ministers; his second made him the longest-serving premier in the nation’s history. This radical transformation in fortunes raises important questions about how political actors can reinvent themselves and alter public opinion of their own capacity to lead. This thesis argues that the projection of a compelling political narrative of national economic regeneration played a key role in Abe Shinzō’s political transformation. I examine this reconstruction of political fortunes through the lens of a strategic narrative framework. Although other academic research has analysed Abe’s transformation through examination of his policies and political networks, there has been a lack of studies exploring how Abe communicated his new political approach to his audiences. Strategic narrative research in the field of International Relations has shown that stories and their formation by political actors play a critical role in shaping the discursive environment in which politics are done. Through careful analysis of the stories Abe Shinzō told during the LDP presidential election campaigns of 2006 and 2012, the general elections of 2012 and 2014, and the Upper House elections of 2007 and 2013, I demonstrate that Abe’s effective deployment of strategic narratives was a crucial factor in his re-emergence as a central figure in post-war Japanese politics and introduce a strategic narrative framework to domestic Japanese politics for the first time. By forming and projecting a compelling narrative focused on a set of economic policies known as ‘Abenomics’, Abe placed himself at the centre of a story of national regeneration; by arguing narratively that Japan’s continued economic recovery was inextricably linked to the success of Abenomics, Abe was able to lead his party to three successive election victories. I also demonstrate Abe’s narrative flexibility, examining the complexification of his strategic narrative over time, introducing the concept of ‘Proactive Contribution to Peace’ as he sought to link his story of national economic regeneration to one of greater Japanese contribution to global security. Crucially, these narratives were also broadly accepted by Abe’s domestic and international media audiences, allowing ’Abenomics’ to become the dominant narrative about the direction of Japanese politics, both within and outside of the country. Overall, I offer a new account of Abe Shinzō’s re-emergence as the central figure in Japanese politics and demonstrate the persuasive power of strategic narratives in the setting of domestic politics.

description: At room temperature, a macroscopic quantum galvanomagnetic effect of Faraday electromagnetic induction was demonstrated under conditions of the capture of single magnetic flux quanta in the edge channels, confined by chains of negative-U centers, in a silicon nanostructure heavily doped with boron, prepared in Hall geometry on an n-type Si (100) substrate. It is shown that this effect leads to the appearance of an induction current when only a constant magnetic field is applied in the absence of an externally applied voltage or a stabilized current.

description: The propagation of light along an infinite 2D chain of silver nanorods is analyzed and the dispersion for this waveguide is computed using field computation for a finite chain of nanorods. In this work, Generalized Multipole Technique is used for the analysis. This method calculates the imaginary and real parts of the propagation constant by exciting the chain in one end and observing propagation of modes along the chain far enough from the excitation. It is shown that a short chain of finite length is sufficient for the calculation of the phase constant while the attenuation constant requires a longer chain. Field distribution is depicted for even and odd modes and it is shown that in the simulated frequency range only two modes can be excited and can propagate along the waveguide.

It can be separated from most similar appearing species be the combination of the broad postpetiole and erect setae on the antennal scapes.

description: Local energy extrema of the bands in momentum space, or valleys, can endow electrons in solids with pseudo-spin in addition to real spin. In transition metal dichalcogenides this valley pseudo-spin, like real spin, is associated with a magnetic moment which underlies the valley-dependent circular dichroism that allows optical generation of valley polarization, intervalley quantum coherence, and the valley Hall effect. However, magnetic manipulation of valley pseudospin via this magnetic moment, analogous to what is possible with real spin, has not been shown before. Here we report observation of the valley Zeeman splitting and magnetic tuning of polarization and coherence of the excitonic valley pseudospin, by performing polarization-resolved magneto-photoluminescence on monolayer WSe2. Our measurements reveal both the atomic orbital and lattice contributions to the valley orbital magnetic moment; demonstrate the deviation of the band edges in the valleys from an exact massive Dirac fermion model; and reveal a striking difference between the magnetic responses of neutral and charged valley excitons which is explained by renormalization of the excitonic spectrum due to strong exchange interactions.

description: Optical observations of the type IIb SN 2013df from a few days to about 250 days after explosion are presented. These observations are complemented with UV photometry taken by \textit{SWIFT} up to 60 days post-explosion. The double-peak optical light curve is similar to those of SNe 1993J and 2011fu although with different decline and rise rates. From the modelling of the bolometric light curve, we have estimated that the total mass of synthesised $^{56}$Ni in the explosion is $\sim0.1$ M$_{\odot}$, while the ejecta mass is $0.8-1.4$ M$_{\odot}$ and the explosion energy $0.4-1.2 \times 10^{51}$erg. In addition, we have estimated a lower limit to the progenitor radius ranging from $64-169$ $R_{\odot}$. The spectral evolution indicates that SN 2013df had a hydrogen envelope similar to SN 1993J ($\sim 0.2$ M$_{\odot}$). The line profiles in nebular spectra suggest that the explosion was asymmetric with the presence of clumps in the ejecta, while the [O\,{\sc i}] $λ$$λ$$6300$, $6364$ luminosities, may indicate that the progenitor of SN 2013df was a relatively low mass star ( $\sim 12-13 $ M$_{\odot}$).

description: Σκοπός της έρευνας ήταν η μελέτη της διαφοροποίησης του τρόπου συγχρονισμού μεταξύ των χεριών κατά την ελεύθερη κολύμβηση με έλξη αντίστασης. Δέκα κολυμβήτριες κολύμπησαν 25 m με μέγιστη ένταση, χωρίς έλξη αντίστασης και με έλξη αντίστασης, που προέρχονταν από μια λεκάνη μικρού μεγέθους. Για την καταγραφή της υποβρύχιας κίνησης των χεριών χρησιμοποιήθηκαν 4 κάμερες (60 Ηζ) και η ψηφιοποίηση επιλεγμένων σημείων πάνω στο σώμα έγινε μέσω του Ariel Performance Analysis System. Για τον καθορισμό του τρόπου συγχρονισμού μεταξύ των δύο χεριών υπολογίστηκε ο δείκτης συγχρονισμού, υπολογίζοντας το χρονικό διάστημα που μεσολαβεί μεταξύ των προωθητικών φάσεων των δύο χεριών. Κατά την κολύμβηση με έλξη αντίστασης, από την εφαρμογή του t—test για εξαρτημένα δείγματα, προέκυψε στατιστικά σημαντική μείωση της κολυμβητικής ταχύτητας (tg= 28.258; ρ<0.05), της συχνότητας (tg= 7.895; ρ<0.05) και του μήκους χεριάς (t9= 10.085; ρ<0.05), ενώ ο δείκτης συγχρονισμού παρουσίασε στατιστικά σημαντική αύξηση (tg= 6.300; ρ<0.05), από -13.5% σε -7.7%. Επίσης, διαπιστώθηκε στατιστικά σημαντική αύξηση της σχετικής διάρκειας της φάσης έλξης (t9= 3.105; ρ<0.05) και της φάσης ώθησης (t9= 4.501; ρ<0.05), ενώ αντίθετα μειώθηκε η σχετική διάρκεια του γλιστρήματος (tg= 3.487; ρ<0.05) και δεν διαφοροποιήθηκε σημαντικά η σχετική διάρκεια της επαναφοράς. Συνεπώς, κατά την κολύμβηση με έλξη αντίστασης μικρού μεγέθους, παρόλο που το πρότυπο συγχρονισμού μεταξύ των δύο χεριών παραμένει στο μοντέλο του πιασίματος, μειώνεται το χρονικό διάστημα που μεσολαβεί μεταξύ των προωθητικών φάσεων των δύο χεριών. Αυτή η διαφοροποίηση οφείλεται στην αύξηση της σχετικής διάρκειας των προωθητικών φάσεων και στη μείωση της σχετικής διάρκειας των μη προωθητικών φάσεων.

description: Perpendicular magnetic anisotropy (PMA) and dynamic magnetization reversal process in [CoFeB $t$ nm/Pd 1.0 nm]$_n$ ($t$ = 0.4, 0.6, 0.8, 1.0, and 1.2 nm; $n$ = 2 - 20) multilayer films have been studied by means of magnetic hysteresis and Kerr effect measurements. Strong and controllable PMA with an effective uniaxial anisotropy up to 7.7$\times$ 10$^6$ J.m$^{-3}$ and a saturation magnetization as low as 200 emu/cc are achieved. Surface/interfacial anisotropy of CoFeB/Pd interfaces, the main contribution to the PMA, is separated from the effective uniaxial anisotropy of the films, and appears to increase with the number of the CoFeB/Pd bilayers. Observation of the magnetic domains during a magnetization reversal process using polar magneto-optical Kerr microscopy shows the detailed behavior of nucleation and displacement of the domain walls.

Reverberation Mapping of IC4329A

description: We present the results of a new reverberation mapping campaign for the broad-lined active galactic nucleus (AGN) in the edge-on spiral IC4329A. Monitoring of the optical continuum with $V-$band photometry and broad emission-line flux variability with moderate-resolution spectroscopy allowed emission-line light curves to be measured for H$β$, H$γ$, and HeII $λ4686$. We find a time delay of $16.3^{+2.6}_{-2.3}$ days for H$β$, a similar time delay of $16.0^{+4.8}_{-2.6}$ days for H$γ$, and an unresolved time delay of $-0.6^{+3.9}_{-3.9}$ days for HeII. The time delay for H$β$ is consistent with the predicted value from the relationship between AGN luminosity and broad line region radius, after correction for the $\sim2.4$mag of intrinsic extinction at 5100A. Combining the measured time delay for H$β$ with the broad emission line width and an adopted value of $\langle f \rangle = 4.8$, we find a central supermassive black hole mass of $M_{\rm BH}=6.8^{+1.2}_{-1.1}\times10^7 M_{\rm \odot}$. Velocity-resolved time delays were measured across the broad H$β$ emission-line profile and may be consistent with an ''M''-like shape. Modeling of the full reverberation response of H$β$ was able to provide only modest constraints on some parameters, but does exhibit agreement with the black hole mass and average time delay. The models also suggest that the AGN structure is misaligned by a large amount from the edge-on galaxy disk. This is consistent with expectations from the unified model of AGNs, in which broad emission lines are expected to be visible only for AGNs that are viewed at relatively face-on inclinations.

description: Beck's type column on Winkler type foundation is the subject of the present analysis. Instead of the Bernoulli-Euler model describing the rod, two generalized models will be adopted: Eringen non-local model corresponding to nano-rods and viscoelastic model of fractional Kelvin-Voigt type. The analysis shows that for nano-rod, the Herrmann-Smith paradox holds while for viscoelastic rod it does not.

Temnothorax pulchellus

description: pulchellus group overview With fifteen species (nine described as new here), the pulchellus group is the largest in the salvini clade. Primarily inhabiting the low elevations of the Caribbean islands and southern Florida, this group has a peculiar bimodal elevational distribution, inhabiting some of the highest points on the island of Hispaniola, but as of yet without any records of mid-elevation collections (Fig. 133). Nest collections of this group, while rare, suggest nesting habits similar to the pastinifer group, i.e., within dead wood and vegetation on or near the ground, often in leaf litter. The general habitus of the members of the pulchellus group is another example of the Macromischa syndrome, with most species having extremely arched mesosomata, often with enlarged femora, and always with broad postpetioles. These characters broadly overlap with the pastinifer group, Temnothorax subditivus, and some members of the sallei clade (e.g., the sallei and iris subclades sensu Prebus (2017)). Use the keys above and the ‘similar species’ sections below to find specific distinguishing characters.
