description: The current capacity of computers makes it possible to perform simulations of small systems with portable, explicit-solvent potentials achieving high degree of accuracy. However, simplified models must be employed to exploit the behaviour of large systems or to perform systematic scans of smaller systems. While powerful algorithms are available to facilitate the sampling of the conformational space, successful applications of such models are hindered by the availability of simple enough potentials able to satisfactorily reproduce known properties of the system. We develop an interatomic potential to account for a number of properties of proteins in a computationally economic way. The potential is defined within an all-atom, implicit solvent model by contact functions between the different atom types. The associated numerical values can be optimised by an iterative Monte Carlo scheme on any available experimental data, provided that they are expressible as thermal averages of some conformational properties. We test this model on three different proteins, for which we also perform a scan of all possible point mutations with explicit conformational sampling. The resulting models, optimised solely on a subset of native distances, not only reproduce the native conformations within a few Angstroms from the experimental ones, but show the cooperative transition between native and denatured state and correctly predict the measured free--energy changes associated with point mutations. Moreover, differently from other structure-based models, our method leaves a residual degree of frustration, which is known to be present in protein molecules.

Bahnhofplätze für Menschen: Das Potential unserer Bahnhofplätze als qualitätsvolle öffentliche
Räume
Creators: name: Theler, Sophia
Publisher: name: Hochschule Luzern – Soziale Arbeit
Year: 2024

description: Ausgangslage. Bahnhöfe spielen eine wichtige Rolle in der Entwicklung von Gemeinden. Sie sind Verkehrsdrehscheiben, die öffentlichen Raum bieten sollen. Ein möglicher Ort dafür kann der Bahnhofplatz sein. Die Innenentwicklung, Klimaerwärmung und Verdrängungsgefahr im Bahnhofsumfeld erhöhen die Anforderungen an Bahnhofplätze. Deshalb steigt ihre Bedeutung als qualitätsvolle öffentliche Räume.

Fragestellungen. Die Arbeit soll aufzuzeigen, wie man aus Bahnhofplätzen qualitätsvolle öffentliche Räume herstellen kann. Dafür werden die Funktionen und Herausforderungen von Bahnhofplätzen eruiert. Kriterien und Massnahmen sollen anschliessend aufzeigen, wie Bahnhofplätze ihr Potential als qualitätsvolle öffentliche Räume entfalten können.

Vorgehen. Um die Fragestellungen zu beantworten, werden der Bahnhofplatz Renens und der Bahnhofplatz Visp als Fallbeispiele analysiert. Grundlage für die Analyse bietet die Raumtriade. Mit diesem Modell untersucht die Autorin den Bahnhofplatz als gebauter und erlebter Raum sowie als Repräsentationsraum. Beobachtungen auf den Bahnhofplätzen sind Bestandteil der Analyse. Zusätzlich liefern Interviews mit Expertinnen und Experten Informationen für die Beantwortung der Fragestellungen. 

Ergebnisse. Die vielseitigen Funktionen von Bahnhofplätzen zeigen auf, welches Potential in ihnen steckt. Bahnhofplätze nehmen eine identitätsstiftende und wertvolle Rolle als öffentliche Räume ein. Die Ansprüche der Nutzenden, die Überlagerungen der Nutzungen, die unterschiedlichen Beteiligten sowie die nötige Bewirtschaftung stellen hohe Anforderungen an Bahnhofplätze. Damit Bahnhofplätze ihr Potential entfalten können, muss Aufenthaltsqualität umfassender gedacht werden. Die Kriterien und Massnahmen umfassen deshalb drei Kategorien: Nutzung (Nutzende und Angebote), Gestaltung (physischer Raum) und Management (Prozess). Schlussendlich zeigen die Ergebnisse der Arbeit auf, dass die Menschen im Fokus stehen müssen, um qualitätsvolle Bahnhofplätze herzustellen.

Nominal restatement
Creators: name: Jasinskaja, Ekaterina
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper identiﬁes, explores and provides a formal analysis to a phenomenon that I will call nominal restatement. Nominal restatement (NR) bears a certain similarity to nominal apposition (NA). However, whether an equality sign can be put between these notions depends largely on our assumptions about the range of facts pertaining to apposition, which is not a matter of perfect consensus. This paper shows that NR goes beyond the notion of NA developed by Potts (2005) and is not covered by his analysis. It also presents a purely pragmatic account of NR in terms of the discourse relation of restatement (Jasinskaja 2006b), which both explains the new observations concerning NR (e.g. quantiﬁcation and scope behaviour) and provides a better explanation to some old observations about NA that are also valid for NR (e.g. case). Finally, I address the question whether the notion of NA can ultimately be done away with by subsuming it under the more general notion of NR and discuss some related problems.

description: In this paper we establish the error rate of first order asymptotic approximation for the tail probability of sums of log-elliptical risks. Our approach is motivated by extreme value theory which allows us to impose only some weak asymptotic conditions satisfied in particular by log-normal risks. Given the wide range of applications of the log-normal model in finance and insurance our result is of interest for both rare-event simulations and numerical calculations. We present numerical examples which illustrate that the second order approximation derived in this paper significantly improves over the first order approximation.

description: The interaction of highly charged ions (HCI) with solids leads to particle sputtering, which can be used for defect-mediated engineering of the properties of the material. Ions can store energy in the form of kinetic and potential energy (sum of the ionization energies) and transfer it to the solid upon impact. The interaction and sputtering mechanisms depend significantly on the projectile energies. However, the relevance of various interaction mechanisms is unknown. Here we show that for slow HCI (5 keV) the interaction mechanisms leading to particle emission by electronic excitation and transferred kinetic energy are independent from each other, which is consistent with our atomistic simulations. We have irradiated substrate supported (Au, SiO$_2$) monolayers of MoS$_2$ with highly charged xenon ions (charge state: 17$+$ - 40$+$), extracted the emitted neutral, post-ionized Mo particles into a time-of-flight mass spectrometer and determined their velocity distributions. We find two main contributions, one at high velocities and a second one at lower velocities, and assign them to kinetic and potential effects respectively. Our data suggests that the dominant mechanism for potential sputtering is related to electron-phonon coupling, while non-thermal processes play no significant role. We anticipate that our work will be a starting point for further experiments and simulations to determine whether the different processes resulting from E$_{pot}$ and E$_{kin}$ can be separated or whether synergistic effects play a role.

description: Medical image fusion is the process of registering and combining multiple images from single or multiple imaging modalities to improve the imaging quality and reduce randomness and redundancy in order to increase the clinical applicability of medical images for diagnosis and assessment of medical problems. Multi-modal medical image fusion algorithms and devices have shown notable achievements in improving clinical accuracy of decisions based on medical images. This review article provides a factual listing of methods and summarizes the broad scientific challenges faced in the field of medical image fusion. We characterize the medical image fusion research based on (1) the widely used image fusion methods, (2) imaging modalities, and (3) imaging of organs that are under study. This review concludes that even though there exists several open ended technological and scientific challenges, the fusion of medical images has proved to be useful for advancing the clinical reliability of using medical imaging for medical diagnostics and analysis, and is a scientific discipline that has the potential to significantly grow in the coming years.

description: Strongly interacting fermionic systems host a variety of interesting quantum many-body states with exotic excitations. For instance, the interplay of strong interactions and the Pauli exclusion principle can lead to Stoner ferromagnetism, but the fate of this state remains unclear when kinetic terms are added. While in many lattice models the fermions' dispersion results in delocalization and destabilization of the ferromagnet, flat bands can restore strong interaction effects and ferromagnetic correlations. To reveal this interplay, here we propose to study the Hofstadter-Fermi-Hubbard model using ultracold atoms. We demonstrate, by performing large-scale DMRG simulations, that this model exhibits a lattice analog of the quantum Hall ferromagnet at magnetic filling factor $ν=1$. We reveal the nature of the low energy spin-singlet states around $ν\approx1$ and find that they host quasi-particles and quasi-holes exhibiting spin-spin correlations reminiscent of skyrmions. Finally, we predict the breakdown of flat-band ferromagnetism at large fields. Our work paves the way towards experimental studies of lattice quantum Hall ferromagnetism, including prospects to study many-body states of interacting skyrmions and explore the relation to high-$T_{\rm c}$ superconductivity.

description: Thanks for the releasing image of supermassive black holes (BHs) by the event horizon telescope (EHT) at the heart of the $M87$ galaxy. After the discovery of this mysterious object, scientists paid attention to exploring the BH shadow features under different gravitational backgrounds. In this scenario, we study the light rings and observational properties of BH shadow surrounded by different accretion flow models and then investigate the effect of model parameters on the observational display and space-time structure of BHs in the framework of our considering system. Under the incompatible configuration of the emission profiles, the images of BHs comprise that the observed luminosity is mainly determined by direct emission, while the lensing ring will provide a small contribution of the total observed flux and the photon ring makes a negligible contribution due to its exponential narrowness. More importantly, the observed regions and specific intensities of all emission profiles are changed correspondingly under variations of parameters. For optically thin accreting matters, we analyze the profile and specific intensity of the shadows with static and infalling accretions models, respectively. We find that with an infalling motion the interior region of the shadows will be darker than in a static case, due to the Doppler effect of the infalling movement. Finally, it is concluded that these findings support that the change of BH state parameters will change the way of space-time geometry, thus affecting the BH shadows dynamics.

description: We demonstrate stable optical microcavities by counteracting the phase evolution of the cavity modes using an amorphous silicon metasurface as one of the two cavity end mirrors. Careful design allows us to limit the metasurface scattering losses at telecom wavelengths to less than 2% and using a distributed Bragg reflector as metasurface substrate ensures high reflectivity. Our first demonstration experimentally achieves telecom-wavelength microcavities with quality factors of up to 4600, spectral resonance linewidths below 0.4 nm, and mode volumes down to below 2.7$λ^3$. We then show that the method introduces unprecedented freedom to stabilize modes with arbitrary transverse intensity profiles and design cavity-enhanced hologram modes. Our approach introduces the nanoscopic light control capabilities of dielectric metasurfaces to cavity electrodynamics and is directly industrially scalable using widespread semiconductor manufacturing processes.

description: A theoretical approach for the non-equilibrium transport properties of nanoscale systems coupled to metallic electrodes with strong electron-phonon interactions is presented. It consists in a resummation of the dominant Feynman diagrams from the perturbative expansion in the coupling to the leads. We show that this scheme eliminates the main pathologies found in previous simple analytical approaches for the polaronic regime. The results for the spectral and transport properties are compared with those from several other approaches for a wide range of parameters. The method can be formulated in a simple way to obtain the full counting statistics. Results for the shot and thermal noise are presented.

description: The motion of quantum particles homogeneously constrained to a curved surface is affected by a curvature induced geometric potential. Here, we consider the case of inhomogeneous confinement and derive the effective Hamiltonian by extending thin-layer procedure, where an extra effective potential appears. This effective potential is relevant to the ground state energy perpendicular to the surface and the morphology of the confining potential. Tiny changes in the thickness are envisioned to induce considerable magnitude of the effective potential. To demonstrate the impact of the inhomogeneity, we apply our method to investigate the coherent transport on a cylindrical surface where a confining potential with two helical ditches is imposed. Numerical analysis reveals that the inhomogeneity of the confinement significantly changes the transport properties. This study develops the method for low-dimensional constrained systems and exhibits the possibility of new degree of control for waveguiding in nanostructures.
Förderung der Chancengleichheit von Frauen durch die Berufswahl: Ansätze für Interventionen der Sozialen Arbeit zur Stärkung von Mädchen bei der Wahl genderuntypischer Berufe

description: Auch im 21. Jahrhundert sind Frauen in der Gesellschaft noch Benachteiligungen – besonders in Bezug auf finanzielle Ressourcen – ausgesetzt und Rollenklischees weit verbreitet. Beide führen zur Reproduktion weiterer Benachteiligungen und potenzieller Diskriminierung aufgrund des Geschlechts. Die gesetzliche Verankerung auf internationaler sowie nationaler Ebene hingegen weist aus, dass Mann und Frau gleichberechtigt sind und das Gesetz für eine rechtliche und tatsächliche Gleichstellung sorgen soll. Die Zahlen zur finanziellen Gleichstellung sprechen eine andere Sprache. Eine ausgewogene Verteilung finanzieller Ressourcen auf die Geschlechter ist jedoch von grosser Bedeutung für deren Gleichstellung in der Gesellschaft. Die Literaturrecherchen zeigten, dass viele Faktoren zu dieser Ungleichheit beitragen. Gerade die starke Geschlechtersegregation auf dem Schweizer Arbeitsmarkt zeigt eine Ungleichheit auf; somit bestehen auch Chancen, durch die Auflösung dieser Aufteilung und mit der Wahl der Ausbildung, Benachteiligungen von Frauen zu vermindern. Im Übergang I, also von der Sekundarstufe I in die Berufswelt, stehen für Mädchen und Jungen im Jugendalter viele Möglichkeiten offen. Entscheiden sich Mädchen für einen geschlechtsuntypischen Beruf, hat dies besonders Auswirkungen auf die Positionierung im Erwerbsleben, ihre finanziellen Mittel und entsprechend die Rolle in der Familie. Ergebnisse aus der Literaturrecherche ergaben, dass viele Faktoren früh in der Biografie auf die Berufswahl einwirken und dadurch die Wahl der Ausbildung vorgezeichnet ist. Inwiefern die Soziale Arbeit mit dem Ziel der Gleichstellung von Frauen und Männern – Mädchen über die Lebensspanne hinweg darin bestärken kann, Genderstereotypen zu überwinden, zeigt diese Arbeit auf.

description: The quantum size effect on the in-plane paramagnetic critical field in Pb nanofilms is investigated with the use of the spin-generalized Bogolubov-de Gennes equations. It is shown that the critical field oscillates as a function of the nanofilm thickness with the period of $\sim2$ ML (even-odd oscillations) modulated by the beating effect. This phenomena is studied in terms of the quantization of the electron energy spectra caused by the confinement of the electron motion in the direction perpendicular to the sample. The calculated values of critical fields for different nanofilm thicknesses are analyzed in the context of Clogston-Chandrasekhar limit. The influence of the thermal effect on the magnetic field induced superconductor to normal metal transition is also discussed. Furthermore, the thickness-dependence of the electron-phonon coupling and its influence on the value of the critical magnetic field are studied.

description: We propose an alternative route to stabilize magnetic skyrmion textures which does not require Dzyaloshinkii-Moriya interaction, magnetic anisotropy, or an external Zeeman field. Instead, it solely relies on the emergence of flux in the system's ground state. We discuss scenarios that lead to a nonzero flux, and identify the magnetic skyrmion ground states which become accessible in its presence. Moreover, we explore the chiral superconductors obtained for the surface states of a topological crystalline insulator when two types of magnetic skyrmion crystals coexist with a pairing gap. Our work opens perspectives for engineering topological superconductivity in a minimal fashion, and promises to unearth functional topological materials and devices which may be more compatible with electrostatic control than the currently explored skyrmion-Majorana platforms.

Expansion of a Bose-Einstein Condensate with Vortices

Year: 2013

description: The expansion of Bose-Einstein condensates (BECs) is numerically studied. Usually, the aspect ratio of a condensate is inverted due to the anisotropy of the uncertainty principle. In turbulent BECs, however, the aspect ratio remains constant. The reason for this phenomenon is still unknown, being a challenging topic in the study of quantum turbulence. Here, the two-dimensional Gross-Pitaevskii equation is solved and the time development of the aspect ratio and of the radii of the condensates are calculated in the presence of vortices. The results indicate that vortex pairs must be added to a condensate in order to expand it while maintaining its aspect ratio. The anisotropy due to the vortex pairs competes with that due to the uncertainty principle so that the aspect ratio remains constant.
Freiwilliges Engagement in Nachbarschaften

Eine qualitative Untersuchung am Beispiel der Siedlung «Am Katzenbach»

description: Freiwilliges Engagement in Nachbarschaften und deren Erforschung bieten insbesondere für Wohnbaugenossenschaften ein grosses Potential. Die Theorie besagt, dass Sozialkapital in Form von Nachbarschaften und freiwilligem Engagement einen wichtigen Beitrag zur sozialen Kohäsion beitragen kann. Im Alltag von Wohnbaugenossenschaften zeigt sich jedoch, dass sich oftmals nur eine Minderheit im Bereich der formellen Freiwilligenarbeit für das Zusammenleben in der Nachbarschaft engagiert. Dass aber grundsätzlich ein Potential an freiwilligem Engagement in Nachbarschaften vorhanden ist, lässt sich aus der aktuellen Forschung ableiten. Daher wird in dieser MAS-Arbeit untersucht, welche Motive und Hemmnisse für ein freiwilliges Engagement in Nachbarschaften von Wohnbaugenossenschaften existieren, welche Formen bevorzugt werden und mit welchen Massnahmen seitens einer Wohnbaugenossenschaft freiwilliges Engagement gefördert werden könnte.

Um diese Fragen zu beantworten, wurde in der Siedlung «Am Katzenbach» der Baugenossenschaft Glattal Zürich (BGZ) eine qualitative Untersuchung mittels Leitfadeninterviews durchgeführt. Die Ergebnisse zeigen, dass neben dem sichtbaren formellem freiwilligem Engagement insbesondere die Nachbarschaftshilfe als eine Sonderform von Freiwilligkeit eine bedeutende Rolle in Nachbarschaften einnimmt. Als zentrale Motive für freiwilliges Engagement werden das Kennenlernen von Nachbar*innen, Interesse am Thema oder auch der Wunsch, einen Beitrag an das Zusammenleben zu leisten, identifiziert. Persönliches Anfragen und das Elternwerden können dabei die Bereitschaft erhöhen, sich in einer Form zu engagieren. Zeitmangel bzw. Vereinbarkeit und formelle Anforderungen stellen hingegen wesentliche Hemmnisse dar. Bevorzugt werden zudem vermehrt konkrete, klar definierte und punktuelle Engagement-Formen, die soziale Interaktion ermöglichen, aber gleichzeitig flexibel und eher unverbindlich gestaltet sind. Dabei könnten digitale Kommunikationsmöglichkeiten unterstützend wirken, um mehr kurzfristiges freiwilliges Engagements zu fördern. Zur Erhöhung des freiwilligen Engagements in Nachbarschaften von Wohnbaugenossenschaften empfiehlt sich eine pro-aktive Vernetzung der informellen sozialen Netzwerke, regelmässige Information und Kommunikation über Engagement-Möglichkeiten sowie das Schaffen von Möglichkeitsräumen. Weiter sollten bauliche Strukturen so gestaltet sein, dass diese Begegnungen und Kontakte zwischen den Bewohner*innen fördern, da dies eine wichtige Grundlage für verschiedene Formen von freiwilligem Engagement in Nachbarschaften ausmacht.

description: We present a modal analysis of metal-insulator-metal (MIM) based metamaterials in the far infrared region. These structures can be used as resonant reflection bandcut spectral filters that are independent of the polarization and direction of incidence because of the excitation of quasimodes (modes associated with a complex frequency) leading to quasi-total absorption. We fabricated large area samples made of chromium nanorod gratings on top of Si/Cr layers deposited on silicon substrate and measurements by Fourier Transform spectrophotometry show good agreement with finite element simulations. A quasimodal expansion method is developed to obtain a reduced order model that fits very well full wave simulations and that highlights excitation conditions of the modes.

Speaker-oriented vs. Subject-oriented modals: A split in implicative behavior
Creators: name: Hacquard, Valentine
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Epistemic and root modals are often expressed by the same lexical items cross-linguistically. This cross-linguistic trend supports a Kratzerian analysis, where modals share a semantic core and where the only difference between an epistemic and a root interpretation depends on context. However, another cross linguistically robust pattern seems to argue against such a unifying account. Namely, epistemics tend to scope high (in particular higher than Tense and Aspect) and roots low: a fact which a Kratzerian account cannot explain, and which has lead to account which hard-wire a specific syntactic position for epistemics and for roots (cf. Cinque 1999). This paper presents a novel account of modals in the spirit of Kratzer (1981, 1991), but where the modal is relative to an event rather than a world of evaluation. This event-relativity can account for the correct interactions of epistemics and roots with Tense and Aspect, without stipulating an interpretation-specific height for modals.

description: Multi-parton distributions in a proton, the nonperturbative quantities needed to make predictions for multiple scattering rates, are poorly constrained from theory and data and must be modelled. All Monte Carlo event generators that simulate multiple parton interactions (e.g. Pythia) contain such a model of multi-parton PDFs. One important theoretical constraint for the case of double parton distributions is provided by the so-called number and momentum sum rules. In this paper we investigate to what extent the double parton distribution functions used in the Pythia event generator obey these sum rules. We also derive the number and momentum sum rules for the triple parton distribution functions and discuss how one can use the Pythia code to construct triple parton distribution functions which approximately satisfy these sum rules.

description: Kent and Taylor's (1998) dialogic communication model posited that a dialogic perspective focuses on attitudes toward each other held by the participants in a communication transaction online. Guided by this assumption, this study explored the dialogic capacity of social media, specifically, Facebook in the context of a state college and how these led to public communication, participation, information bridge, and community cohesion. Through quantitative content analysis and key informant interviews. this study examined the dialogic internet principles implemented in a state college and an institution's accomplishments. These dialogic principles include conservation of visitors, generation of a return visit, dialogic loop, and information of interests to the public, and organizational engagement. Results showed that the state college used a variety of dialogic principles on Facebook. However, based on the multiple regression analysis, the principle of conservation of visitors and organizational engagement effectively were least subscribed despite its potential to enhance public engagement outcomes. Therefore, it is vital to identify issues that stakeholders considered as necessary that required feedback ulate discussions rather than simply using platforms to promote campus events. As well, findings from qualitative data demonstrate that a state college relied on social media more to disseminate information rather than a dialogic and interactive medium for governance.

description: In the framework of dependent risks it is a crucial task for risk management purposes to quantify the probability that the aggregated risk exceeds some large value u. Motivated by Asmussen et al. (2011) in this paper we introduce a modified Asmussen-Kroese estimator for simulation of the rare event that the aggregated risk exceeds u. We show that in the framework of log-Gaussian risks our novel estimator has the best possible performance. For the more general class of log-elliptical risks with marginal distributions in the Gumbel max-domain of attraction we propose a modified Rojas-Nandayapa estimator of the rare events of interest. Numerical results demonstrate the excellent performance of our novel Asmussen-Kroese algorithm.

description: Perpendicular exchange bias has been manipulated by changing ferromagnetic film thickness and spacer layer in Pt/Co/(Pt, Cr)/CoO thin films. The exchange bias characteristics, blocking temperature, magnetization of thin films strongly depend on the spacer layer (Pt, Cr) between ferromagnetic and antiferromagnetic layers. While Pt/Co/Pt/CoO thin films show perpendicular exchange bias, Pt/Co/Cr/CoO has easy magnetization axis in the film plane. We have also observed very small hysteretic behavior from the hard axis magnetization curve of Pt/Co/Cr/CoO film. This can be attributed to misalignment of the sample or small perpendicular contribution from Pt/Co bottom interface. We have also investigated the temperature and spacer layer dependent exchange bias properties of the samples by VSM magnetometry. We observed higher HEB and HC for the thicker Co layer in the Pt/Co/Pt/CoO sample. In addition, onset of exchange bias effect starts at much lower temperatures for Pt/Co/Cr/CoO thin film. This clearly shows that Cr spacer layer not only removes the perpendicular exchange bias, but also reduces the exchange interaction between Co and CoO and thus lowers the blocking temperature.

description: We study the rotational (yrast) spectra of dilute two-component atomic Bose gases in the low angular momentum regime, assuming equal interspecies and intraspecies interaction. Our analysis employs the composite fermion (CF) approach including a pseudospin degree of freedom. While the CF approach is not {\it a priori} expected to work well in this angular momentum regime, we show that composite fermion diagonalization gives remarkably accurate approximations to low energy states in the spectra. For angular momenta $0 < L < M$ (where $N$ and $M$ denote the numbers of particles of the two species, and $M \geq N$), we find that the CF states span the full Hilbert space and provide a convenient set of basis states which, by construction, are eigenstates of the symmetries of the Hamiltonian. Within this CF basis, we identify a subset of the basis states with the lowest $Λ$-level kinetic energy. Diagonalization within this significally smaller subspace constitutes a major computational simplification and provides very close approximations to ground states and a number of low-lying states within each pseudospin and angular momentum channel.

description: Background: Blood pressure (BP) monitoring is an essential clinical tool for hypertension diagnosis. Conventional cuff-based methods of BP measurement are limited by their discontinuous nature. The new frontier of cuffless techniques may enable widespread, high frequency, BP estimation in the community. This thesis investigates the relationship between BP and arterial stiffness parameters by examining plausible calibration techniques for use in cuffless devices. Methods: Seated BP measurements were made using the first commercially released cuffless device (Casio BP-100 watch), with a two-point calibration obtained using a BP intervention (exercise) and compared to cuff-based measurements. A five-point calibration technique, was undertaken using hydrostatic changes to BP and corresponding pulse arrival time (PAT) measurements by linear regression. Calibration curves were assessed for repeatability over 60 days and BP estimates were assessed by mixed model analysis. Results: The mean difference in watch- and cuff-based measurements were 1±20 mmHg (p>0.05) for both systolic BP (SBP) and diastolic BP (DBP), with poor correlation for both (SBP: R=0.36, p=0.13; DBP: R=0.044, p=0.37). Calibration curves obtained using hydrostatic pressure changes had a mean slope of -1198±873 mmHg·s-1 and intercept 288±153 mmHg. Curves had good repeatability, with mean changes of -185±1270 mmHg·s-1 and 39±228 mmHg for slope and intercept respectively after 60 days. DBP estimates made using PAT and hydrostatic calibration curves had a mean difference of 2.4±18 mmHg from cuff-based measurements. PAT-based estimates accurately tracked directional changes in Cuff-BP. Conclusions: These findings present the utility of multipoint calibration curves for use in cuffless BP estimation. Calibration curves obtained by the hydrostatic effect showed repeatability and acceptable estimation accuracy using PAT. Future research is needed regarding the integration of these calibration methods in wearable devices and the effects of PAT confounders.

description: In the previous works the significance of the symmetric and non-symmetric ion-atom absorption processes in far UV and EUV regions within a model of the quiet Sun atmosphere, has been studied. The considered processes were the processes of the photo-dissociation of the molecular ions H$_{2}^{+}$ and H$X^{+}$ and absorption processes in H+H$^{+}$ and H$+X^{+}$ collisions, where $X$ denotes the metal atom. As the continuation of the previous investigation, these processes are considered also within the corresponding sunspot model. In this work the non-symmetric ion-atom absorption processes are considered with $X=$ Mg, Si, etc. It was analyzed the significance of such processes in far UV and EUV regions in comparison with the concurrent absorption processes, especially with the processes of the photo-ionization of the metal atoms (Na, Mg, Ca, etc.) which were not included in the consideration in the case of the quiet Sun atmosphere. From our analysis it follows that the non-symmetric ion-atom absorption processes considered here, are significant not only for quiet Sun modeling but also for sunspots and should be included {\it ab initio} in both cases.

Beyond the (in)definiteness restriction: A unified semantics for have
Creators: name: Gutierrez-Rexach, Javier
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper, the main properties of the verb have and their connection with the (in)definiteness restriction are studied. Several varieties are characterized, in addition to the well-known existential-have construction: restricted existence, the locative reading, the essential and accidental readings, idiomatic constructions, etc. It is argued that it is possible to provide a uniform semantics for these constructions, starting with the idea that have denotes a function attributing essential properties. The proposed analysis is implemented in Generalized-Quantifier Theory.
