description: The implementation of quantum repeaters needed for long-distance quantum communication requires the generation of quantum entanglement distributed among the elementary links. These entanglements must be swapped among the quantum repeaters through Bell-state measurements. This study aims to improve the entanglement generation rate by frequency multiplexing the Bell-state measurements. As a preliminary step of the frequency-multiplexed Bell-state measurements, three frequency modes are mapped to a temporal mode by an atomic frequency comb prepared in $\mathrm{Pr^{3+}}$ ion-doped $\mathrm{Y_2SiO_5}$ crystals using a weak coherent state, and Hong-Ou-Mandel interference, which is a measure of the indistinguishability of two inputs, is observed in each frequency mode by coincidence detection. The visibility for all the modes was 40%-42% (theoretically up to 50%). Furthermore, we show that a mixture of different modes is avoided. The present results are connected to frequency-selective Bell-state measurements and therefore frequency-multiplexed quantum repeaters.

description: Contributions to the growing environmental concerns by internal combustion engines (ICEs) is the impetus of this research. Therefore, the tribological behavior of lubricants formulated with nano/mineral, nano/bio, and bio/mineral combinations were investigated for the improvements to ICE performance by reducing friction, wear, fuel consumption and exhaust emissions. Mineral-based multigrade engine oil (15W40) was chosen as the reference oil to govern the research. Coconut oil (CCO) was chosen with 15W40 as bio and mineral-base stocks respectively for sample formulations. Graphene (G), Al2O3, TiO2, Al2O3/G, TiO2/G and TiO2/reduced graphene oxide (r-GO) were utilized as nano-additives to blend with both mineral and bio-based formulations. Identity of the selected nanomaterials were confirmed using X-ray powder diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FT-IR) and Raman analyses. Identified substandard of CCO were improved and characterized using differential scanning calorimetry (DSC), pour point, titration, viscometry, simultaneous thermal analysis (STA), rheometric and FT-IR analyses. Factors influencing the dispersion stability of nano/mineral and nano/bio formulations were investigated, and optical absorbance and stability observation tests were used to optimize the performance, with the results presented and discussed. Friction tests were performed using a linear reciprocating tribometer in 3 Phases to analyze the effect of formulated lubricants at elevated temperatures using piston ring and cylinder liner segments of an ICE as test specimens. Wear scars of test specimens were analyzed using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and 3D non-contact optical profilometry to investigate morphologies, elemental deposition, and surface texture of wear surfaces respectively. Specific fuel consumption and exhaust emissions were tested using a dynamometer test-rig and an exhaust analyzer. Industrial generator was utilized for used engine oil sample analysis.

description: Traditional orthodontic treatments do not adequately address the skeletal problems of retrognathic, hyperdivergent, Class II adolescents; the few approaches that do require long-term patient compliance. This paper introduces a novel approach using miniscrew implants (MSIa) and growth to treat retrognathic hyperdivergent adolescents. Nine consecutive patients were evaluated at the start of treatment (13.2 ±1.1 years of age) and again at the end of the orthopedic phase (after 1.9 ±0.3 years). Each patient had two MSIs placed in either side of the palate. Coil springs (150 g) extended from the MSIs to a RPE, which served as a rigid segment for intruding the maxillary premolar and molars. Two additional MSIs were placed between the first mandibular molars and second premolars; coil spring (150 g) extended from the MSIs to hold or intrude the mandibular molars. Prior to treatment, the patients exhibited substantial and significant mandibular retrusion (Z-score=−1.0), facial convexity (Z-score=0.7), and hyperdivergence (Z-score=1.6). Treatment produced consistent and substantial orthopedic effects. The chin was advanced an average of 2.4 mm, the SNB angle increased by 2.1°, the mandibular plane angle decreased 3.9°, and facial convexity decreased by approximately 3.2°. Questionnaires showed that this treatment approach was not painful or uncomfortable; the majority of the patients indicated that they were very likely to recommend the treatment to others. Treatment was accomplished by titrating the amount of orthodontic intrusion performed based on the individuals’ growth potential.

description: La tradizionale teoria economica assume che gli individui sono egoisti. In particolare, sono esclusivamente interessati al proprio benessere economico non considerando i benefici che la loro azione causa agli altri. L’assunzione di individui egoisti non `e capace di spiegare una serie di importanti fenomeni e problemi. Gli individui quotidianamente si trovano ad affrontare attivit`a che sono costose per loro stessi e delle quali beneficiano altri. Essi votano, trascorrono tempo in attivit`a di volontariato, aiutano estranei, contribuiscono ad organizzazioni politiche e caritatevoli, donano il sangue, e a volte rischiano o sacrificano la loro vita per gli altri. Una possibile spiegazione per queste azioni `e che il comportamento degli individui pu`o essere influenzato da considerazioni di altruismo, equit`a e reciprocit`a (vedi per esempio Fehr e Schmidt, 1999). In questo senso, gli individui possono essere intrinsecamente motivati: “One is said to be intrinsically motivated to perform an activity when he receives no apparent reward except the activity itself” (Deci, 1971). In questa tesi, analizzo come la motivazione intrinseca influenza il comportamento degli individui in un numero di diverse situazioni, cos`ı come in un problema di contribuzione al bene pubblico o di selezione di individui motivati tra diversi settori. Inoltre, sono interessata nel capire come gli individui rispondono a diversi incentivi in maniera tale da poter meglio informare le politiche economiche. .. [a cura dell'Autore]
description: Traditional economic theory assumes that individuals are self-interested. Namely, they are exclusively interested in their own utility disregarding the benefits that their action causes to the others. However, the assumption of selfish individuals proves unable to explain a number of important phenomena and puzzles. Individuals frequently engage in activities that are costly to themselves and mostly benefit others. They vote, volunteer time, help strangers, give to political or charitable organizations, donate blood, and sometimes even risk or sacrifice their life for strangers. A possible explanation for these actions is that the behavior of the individuals can be affected by altruistic, equity and reciprocity considerations (see for example Fehr and Schmidt, 1999). In this sense individuals can be intrinsically motivated: “One is said to be intrinsically motivated to perform an activity when he receives no apparent reward except the activity itself” (Deci, 1971). In this thesis, I analyze how intrinsic motivation affects individuals’ behavior in a number of different situations, such as a public good contribution problem or a school selection of motivated teachers. Furthermore, I am interested in understanding how people respond to different incentives in order to better inform policies. .. [edited by Author]

description: An intriguing possibility that can address pathologies in both early universe cosmology (i.e. the horizon problem) and quantum gravity (i.e. non-renormalizability), is that particles at very high energies and/or temperatures could propagate arbitrarily fast. A concrete realization of this possibility for the early universe is the Tachyacoustic (or Speedy Sound) cosmology, which could also produce a scale-invariant spectrum for scalar cosmological perturbations. Here, we study Thermal Tachyacoustic Cosmology (TTC), i.e. this scenario with thermal initial conditions. We find that a phase transition in the early universe, around the scale of Grand Unified Theories (GUT scale; $T\sim 10^{15}$ GeV), during which the speed of sound drops by $25$ orders of magnitude within a Hubble time, can fit current CMB observations. We further discuss how production of primordial black holes constrains the cosmological acoustic history, while coupling TTC to Horava-Lifshitz gravity leads to a lower limit on the amplitude of tensor modes ($r \gtrsim 10^{-3}$), that are detectable by CMBPol (and might have already been seen by the BICEP-Keck collaboration).

description: Frequency combs from continuous-wave-driven Kerr-nonlinear microresonators have evolved into a key photonic technology with applications from optical communication to precision spectroscopy. Essential to many of these applications is the control of the comb’s defining parameters, i.e., carrier-envelope offset frequency and repetition rate. An elegant and all-optical approach to controlling both degrees of freedom is the suitable injection of a secondary continuous-wave laser into the resonator onto which one of the comb lines locks. Here, we study experimentally such sideband injection locking in microresonator soliton combs across a wide optical bandwidth and derive analytic scaling laws for the locking range and repetition rate control. As an application example, we demonstrate optical frequency division and repetition rate phase-noise reduction to three orders of magnitude below the noise of a free-running system. The presented results can guide the design of sideband injection-locked, parametrically generated frequency combs with opportunities for low-noise microwave generation, compact optical clocks with simplified locking schemes and more generally, all-optically stabilized frequency combs from Kerr-nonlinear resonators.

description: Tools for controlling electrically the motion of magnetic skyrmions are important elements towards their use in spintronic devices. Here, we propose and demonstrate the transport of skyrmions via GHz and THz electric pulses. The method relies on using polarization textured pulses such that the skyrmion experiences (via its inherent magnetoelectricity) the out-of-plane and in-plane components of the pulse electric field. It is shown how the electric field drags efficiently the skyrmion. The control of the skyrmion motion depends solely on the amplitude of electric fields, frequency, polarization, or phase in case two pulses are applied. Micromagnetic calculations supported by analytic modeling and analysis indicate the experimental feasibility of the control scheme.

description: An $R$--band photopolarimetric variability analysis of the TeV bright blazar W Comae, between 2008 February 28 and 2013 May 17, is presented. The source showed a gradual tendency to decrease its mean flux level with a total change of ~3~mJy. A maximum and minimum brightness states in the $R$-band of 14.25$\pm$0.04 and 16.52$\pm$0.1~mag respectively were observed, corresponding to a maximum variation of $Δ$F = 5.40 mJy. We estimated a minimum variability timescale of $Δ$t=3.3 days. A maximum polarization degree $P$=33.8\%$\pm$1.6\%, with a maximum variation of $Δ$P = 33.2\%, was found. One of our main results is the detection of a large rotation of the polarization angle from 78\degr to 315\degr ($Δθ\sim$237\degr) that coincides in time with the $γ$-ray flare observed in 2008 June. This result indicates that both optical and $γ$-ray emission regions could be co-spatial. During this flare, a correlation between the $R$-band flux and polarization degree was found with a correlation coefficient of $r_{F-p}=0.93\pm$0.11. From the Stokes parameters we infer the existence of two optically thin synchrotron components that contribute to the polarized flux. One of them is stable with a constant polarization degree of 11\%. Assuming a shock-in jet model during the 2008 flare, we estimated a maximum Doppler factor $δ_D\sim 27$ and a minimum of $δ_D\sim 16$; a minimum viewing angle of the jet $\sim$2\degr.0; and a magnetic field $B \sim$ 0.12~G.

description: In the era of rapidly evolving conversational services, chatbots are the next important technological advancement, allowing businesses and other organizations to enable users to communicate with messaging systems based on artificial intelligence (AI) and machine learning technology. The increasing use of chatbots in messaging platforms suggests that this technology is one of the most preferred channels for customer services. This is, for example, evident from the number of active bots on Facebook and Messenger, which has increased from 100,000 bots in 2017 to over 400,000 bots in 2020. The positive feedback from users is leading to more and more companies investing in bots. Due to the growing significance of chatbots, there are many platforms available in the market to develop a chatbot. A few of them are Rasa, Dialogflow, Amazon lex, etc. Each of them has its strengths and weaknesses concerning various aspects such as documentation, configuration, testing, deployment, resources required, etc. In this paper, we will have a look at an AI Rasa chatbot built for a dialog management system for the Pepper robot deployed in the context of healthcare. Pepper robot is a humanoid robot developed by SoftBank Robotics. This type of robot is mainly used at receptions, during various explanations, at school, etc. The robot is 1.2 m tall and weighs 28 kg. It will operate on the HoSmartAI platform, developed within the EU project HoSmartAI. HoSmartAI is a European project which aims to assist in digitizing the European health sector to make the system stronger, efficient, sustainable, and resilient. The project started in January 2021 and will run until May 31, 2024. During this time, our team is developing a humanoid robot that will help with hospital care, which we will also present in this article.

description: Der vorliegende Beitrag untersucht das Phänomen Aktionärsaktivismus mittels der Fallstudienmethodik als qualitativem Forschungsansatz anhand von drei Schweizer Publikumsgesellschaften. Die Untersuchung bezieht sich auf den Zeitraum 2015 bis 2019. Die Auswahl geeigneter Unternehmen erfolgte aufgrund einer Auswertung aller publizierten Meldungen von Finanz und Wirtschaft (FuW). Die auf dieser Basis selektierten Schweizer Unternehmen Meyer Burger, GAM und Clariant wurden anschliessend im Hinblick auf folgende Forschungsfragen untersucht: • Welches sind bedeutende Aktivitätsfelder, in denen die aktivistischen Aktionäre ihre Einflussnahme geltend machten? • Welche Handlungsmuster lassen sich im Rahmen der aktiven Einflussnahme aktivistischer Aktionäre auf das Management betroffener Schweizer Unternehmen identifizieren? • Hat die Einflussnahme aktivistischer Investoren bei Schweizer börsenkotierten Unternehmen zu einem Mehrwert für diese geführt? Bezogen auf die genannten Forschungsfragen zeigen sich unterschiedliche Ergebnisse: Einzelne aktivistische Investoren konnten im untersuchten Zeitraum zwar erhebliche Gewinne für sich erwirtschaften, jedoch nicht auf langfristige und nachhaltige Sicht. Aktionärsaktivismus zeigte sich im Rahmen der Einzelfallstudienanalyse in verschiedenen Formen und Strategien. Die Absichten der aktivistischen Aktionäre konnten jedoch nicht eindeutig und abschliessend ermittelt werden. Die Untersuchung zeigt weiterhin, dass das Interesse des Managements im Kontext von Mergers & Acquisitions oft mit den Interessen der langfristigen Investoren kollidiert, welche quasi als Gegenreaktion zu Aktionärsaktivismus neigen, um ihre Forderungen durchzusetzen. Eine Fortführung des Forschungsprojekts soll in einem nächsten Schritt weitere Erkenntnisse liefern.

description: We report on the determination of astrometric, spin and orbital parameters for PSR J1518+0204C, a "black widow" binary millisecond pulsar in the globular cluster M5. The accurate position and orbital parameters obtained from radio timing allowed us to search for the optical companion. By using WFC3/HST images we identified a very faint variable star (m_F390W > 24.8, m_F606W > 24.3, m_F814W > 23.1) located at only 0.25" from the pulsar's timing position. Due to its strong variability, this star is visible only in a sub-sample of images. However, the light curve obtained folding the available data with the orbital parameters of the pulsar shows a maximum at the pulsar inferior conjunction and a possible minimum at the pulsar superior conjunction. Furthermore, the shape of the optical modulation indicates a heating process possibly due to the pulsar wind. This is the first identification of an optical companion to a black widow pulsar in the dense stellar environment of a globular cluster.

description: L’argomento principale di questa tesi è lo studio del modo in cui le forme lessicalmente ambigue di una lingua siano rappresentate all’interno del lessico mentale dei parlanti. L’esistenza di parole che veicolano significati e/o sensi multipli (ad esempio, credenza, mora, ecc.) è una caratteristica propria del linguaggio naturale. I parlanti della maggior parte delle lingue esistenti si imbattono quotidianamente in parole ambigue dal punto di vista lessicale, la cui corretta interpretazione avviene principalmente mediante il ricorso al contesto linguistico in cui tali forme sono inserite. ..

description: The aim of this work is to focus on how lexically ambiguous words are represented in the mental lexicon of speakers. The existence of words with multiple meanings/senses (e.g., credenza, mora, etc. in Italian) is a pervasive feature of natural language. Routinely speakers of almost all languages encounter ambiguous words, whose correct interpretation is made by recurring to the linguistic context in which these forms are inserted. ..

Misner-Sharp Mass in $N$-dimensional $f(R)$ Gravity

description: We study the Misner-Sharp mass for the $f(R)$ gravity in an $n$-dimensional (n$\geq$3) spacetime which permits three-type $(n-2)$-dimensional maximally symmetric subspace. We obtain the Misner-Sharp mass via two approaches. One is the inverse unified first law method, and the other is the conserved charge method by using a generalized Kodama vector. In the first approach, we assume the unified first still holds in the $n$-dimensional $f(R)$ gravity, which requires a quasi-local mass form (We define it as the generalized Misner-Sharp mass). In the second approach, the conserved charge corresponding to the generalized local Kodama vector is the generalized Misner-Sharp mass. The two approaches are equivalent, which are bridged by a constraint. This constraint determines the existence of a well-defined Misner-Sharp mass. As an important special case, we present the explicit form for the static space, and we calculate the Misner-Sharp mass for Clifton-Barrow solution as an example.

Integrated systemic approach

description: Among the objectives of the paper there is the need to show that the SDGS for 2030 are strongly interrelated and that, at least for water, perhaps owing to the universal character of the resource, they need to be addressed with an integrated systemic approach. For this rea-son, we want to highlight the cultural value of water, as this is considered a fundamental step towards sustainable development. The text presents a review of the data on the main issues related to Objective 6, with a view to providing a broad and detailed picture of this phenomenon. The aim is to provide useful elements for the reasoning that the social sciences have to perform in their role in the face of the challenges of time. Therefore, some key concepts to be implemented in sociology will be indicated, as well as some indications of method, within a theoretical framework that refers to deep Eco-humanism and to the roots of planetary cosmopolitanism.
Inferior alveolar nerve injury following orthognathic surgery: a review of assessment issues: INFERIOR ALVEOLAR NERVE INJURY
Creators: name: ESSICK, G.
name: PHILLIPS, C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: The sensory branches of the trigeminal nerve encode information about facial expressions, speaking and chewing movements, and stimuli that come into contact with the orofacial tissues. Whatever the cause, damage to the inferior alveolar nerve negatively affects the quality of facial sensibility as well as the patient's ability to translate patterns of altered nerve activity into functionally meaningful motor behaviours. There is no generally accepted, standard method of estimating sensory disturbances in the distribution of the inferior alveolar nerve following injury. Assessment of sensory alterations can be conducted using three types of measures: (i) objective electrophysiological measures of nerve conduction, (ii) sensory testing (stimulus) measures and (iii) patient report. Each type of measure with advantages and disadvantages for use are reviewed.
Converting one photon into two via four-wave mixing in optical fibers

description: Observing nonlinear optical quantum effects or implementing quantum information protocols using nonlinear optics requires moving to ever-smaller input light intensities. However, low light intensities generally mean weak optical nonlinearities, inadequate for many applications. Here we calculate the performance of four-wave mixing in various optical fibers for the case where one of the input beams is a single photon. We show that in tapered chalcogenide glass fibers (microwires) a single photon plus strong pump beam can produce a pair of photons with probability 0.1%, much higher than in previous work on bulk and waveguided crystal sources. Such a photon converter could be useful for creating large entangled photon states, for performing a loophole-free test of Bell's inequalities, and for quantum communication.

description: Socially assistive robots have the potential to help healthcare professionals take care of patients facing different diseases, including cancer, but their uptake is relatively slow. In this short narrative review, we summarize the existing research on factors that are associated with the acceptance of social robots in healthcare (and beyond) and present evidence for the important role of perceived usefulness, perceived enjoyment, and trust. We then use this knowledge to propose an acceptance-oriented methodological framework for implementing social robots in oncological settings.

description: Several lines of evidence support a functional interaction between the cardiovascular and pain regulatory systems. Elevated resting blood pressure is consistently associated with reduced responsiveness to experimental pain stimuli in healthy normotensive subjects. This prospective observational study was designed to evaluate the relationship between preoperative resting arterial blood pressure and postoperative pain in patients undergoing non-surgical endodontic treatment (also known as root canal therapy).

Correlation structures, Many-body Scattering Processes and the Derivation of the Gross-Pitaevskii Hierarchy

description: We consider the dynamics of $N$ bosons in three dimensions. We assume the pair interaction is given by $N^{3β-1}V(N^{β}\cdot )$ . By studying an associated many-body wave operator, we introduce a BBGKY hierarchy which takes into account all of the interparticle singular correlation structures developed by the many-body evolution from the beginning. Assuming energy conditions on the $N$-body wave function, for $β\in \left( 0,1\right] $, we derive the Gross-Pitaevskii hierarchy with $2$-body interaction. In particular, we establish that, in the $N\rightarrow \infty $ limit, all $k$-body scattering processes vanishes if $k\geqslant 3$ and thus provide a direct answer to a question raised by Erdös, Schlein, and Yau in [31]. Moreover, this new BBGKY hierarchy shares the limit points with the ordinary BBGKY hierarchy strongly for $β\in \left( 0,1\right) $ and weakly for $β=1$. Since this new BBGKY hierarchy converts the problem from a two-body estimate to a weaker three body estimate for which we have the estimates to achieve $β<1$, it then allows us to prove that all limit points of the ordinary BBGKY hierarchy satisfy the space-time bound conjectured by Klainerman and Machedon in [47] for $β\in \left( 0,1\right) $.
