Minori, capacità di discernimento ed esercizio della sorveglianza da parte degli insegnanti

description: a) Vigilanza, capacità di discernimento apprezzabile e doveri di 
protezione. 
L’insegnante può essere chiamato a rispondere dell’illecito dell’allievo in forza di diversi titoli: a) dell’art. 2047 c.c. nell'ipotesi in cui lo scolaro, per la giovanissima età, sia privo di una apprezzabile capacità di discernimento; b) dell’art. 2048 c.c. allorquando lo studente sia in grado di rapportarsi correttamente con il mondo esterno e abbia, per ciò stesso, la cognizione circa le conseguenze dei propri comportamenti. 
Accanto a queste ipotesi, che hanno esclusivo riguardo al danno che l’allievo abbia procurato a terzi, è configurabile anche una ulteriore responsabilità dell’insegnante per le lesioni che lo studente si sia autocagionato: la giurisprudenza, invero, è sempre più propensa all'idea che il docente sia investito di un generale ‘‘obbligo di protezione’’ in favore dello stesso scolaro, quale esplicazione dell’inderogabile dovere di solidarietà dell’art. 2 Cost., nascente dal contatto sociale (giuridicamente qualificato) con il minore. 

b) Natura della responsabilità. 
Sebbene buona parte della giurisprudenza di legittimità si esprima 
ancora in termini di culpa in re ipsa, ricollegando l’imputazione alla presunzione di una negligente sorveglianza, sta di fatto che la responsabilità cui l’insegnante è esposto ha natura oggettiva. Invero, tanto l’art. 2047 c.c., quanto il 2048 c.c., non contengono alcun riferimento alla diligenza profusa dal docente nell'esercizio della vigilanza, richiedendo piuttosto, quanto alla prova liberatoria, la dimostrazione positiva del caso fortuito che abbia reso impossibile l’impedimento del fatto illecito dello studente. 
E anche quando il titolo dell’imputazione sia il contatto sociale insegnante-allievo, la responsabilità ha natura oggettiva, richiedendosi al docente la prova dell’impossibilità sopravvenuta della prestazione (vale a dire del dovere di protezione), per causa non imputabile. 

c) Diversi titoli di responsabilità, un’unica prova liberatoria. 
Ritengo che, come la più recente e accreditata dottrina sostiene, l’onere probatorio incombente sull'insegnante per andare esente da responsabilità sia, tanto nell'ipotesi dell’art. 2047 c.c., quanto dell’art. 2048 c.c., e a maggior ragione del contatto sociale, decisamente prossima a quella richiesta dall'art. 1218 c.c., non essendo sufficiente la dimostrazione di aver diligentemente e prudentemente vigilato sulla condotta dell’allievo. Il danneggiato ne risulta, evidentemente, avvantaggiato, anche sotto il profilo della prescrizione del diritto al risarcimento: cinque anni nelle prime due ipotesi, dieci anni nella seconda.

G-invariant Persistent Homology

Subjects: MAT/03 Geometria

description: Classical persistent homology is not tailored to study the action of transformation groups different from the group Homeo(X) of all self-homeomorphisms of a topological space X. In order to obtain better lower bounds for the natural pseudo-distance d_G associated with a subgroup G of Homeo(X), we need to adapt persistent homology and consider G-invariant
persistent homology. Roughly speaking, the main idea consists in defining persistent homology by means of a set of chains that is invariant under the action of G. In this paper we formalize this idea, and prove the stability of G-invariant persistent homology with respect to the natural pseudo-distance d_G. We also show how G-invariant persistent homology could be used in applications concerning shape comparison.
Brainstorming : how the brain sciences can inform social justice strategies
Creators: name: Brillinger, Marc Andrew
Publisher: name: University of British Columbia
Year: 2014

description: Anthropogenic climate disruption (global warming) and income inequality are in the process of spiraling out of control, pushing humanity to the brink of global collapse and mass extinction of species. Underlying this profound issue is an epic struggle taking place between two alternate worldviews. Corporate institutional power has morphed economics, capitalism and the “free market” into a suicide machine that increasingly extracts, exploits and selfishly hordes the bulk of the world’s wealth for the few. The obscene wealth and power of the plutocrats and oligarchs has rigged both economics and politics to benefit the one percent and destroy the environment. Alternately, social justice led by activists have made valiant attempts to slow down this process and regain some sanity with a return to community, sociality and cooperation. A world worth living in hangs precariously in the balance. This interdisciplinary research focuses on the critical, yet unexplored, intersection of social justice and the burgeoning brain sciences. The “brain sciences” refers to the rapidly increasing interdisciplinary understanding (from neuroscience, biology, social sciences etc.) of the human brain, mind, consciousness and their relationship to institutions, cultures, society and human belief and behaviour. A synthesis of the knowledge arising out of the brain sciences, as it applies to existing social activist strategies and tactics, now seems a necessity in the attempt to restrain corporate institutional power that is currently running amok in North America and globally. Extensive interviews with fifteen North American activists on the current state of social justice movements and their understandings of the brain sciences comprised the core of the research. Using grounded theory methodology, initial analysis confirmed that corporate institutional power was the roadblock, obfuscating any positive social change on both anthropogenic climate disruption and income inequality. Deeper analysis of the data, along with the integration of the brain sciences, resulted in a specific strategic recommendation: A global mythology for the 21st century, cognizant of the science of our time and powered by moral outrage, has to “culturally evolve” and spread around the world inhabiting many minds in many places enabling a global cultural environment that nurtures connection, cooperation, cognition and childhood. We can be magnificent, together.

description: This article explores the war’s impact on women’s economic and legal status in Switzerland, a country indirectly affected by the war. It examines the forms and directions of women’s mobilisation as well as the differing reactions of charitable women’s groups and the women workers’ movement to changes affecting nutrition and waged labour. The hopes of women’s associations that they would secure the vote in return for a commitment to soldiers’ welfare and food security were dashed. The male-defined link between readiness to defend the country and civil rights became further entrenched for many years after the war. Pacifist women, on the other hand, were able to use Switzerland’s special position to develop an international network.

description: The optimum design of microwave active mixers has been accomplished using powerful and advanced design-oriented non-linear techniques. Optimum loads at all relevant frequencies (RF, IF, LO, Image) are determined, using a combination of a frequency-domain (Spectral Balance) non­linear algorithm and a numerical scheme for optimum load determination. Moreover, a simplified and fairly accurate quasi-linear method has been developed for a fast and inexpensive preliminary evaluation of mixer's performances.

description: Die vorliegende Arbeit beschäftigt sich mit der Fragestellung, ob beim Rektumkarzinom eine Ausbeute von 12 Lymphknoten ausreichend ist. Dazu wurden die Entwicklung der Lymphknotenausbeute im Verlauf der Zeit, der Einfluss verschiedener Faktoren auf diese sowie die Bedeutung für das Langzeitüberleben untersucht. Im Zeitraum vom 01. Januar 2000 bis zum 31. Dezember 2010 wurden 21317 Patienten aus 381 deutschen Krankenhäusern mit einem primären, histologisch gesicherten und operierten Rektumkarzinom in die multizentrische Beobachtungsstudie eingeschlossen. Eine durchschnittliche Lymphknotenausbeute von mindestens 12 Lymphknoten konnte zu jedem Untersuchungszeitpunkt, bei jeder Operationsmethode und bei jedem Hospital Volume beobachtet werden. Unabhängig davon wurde eine weitere Steigerung der Lymphknotenausbeute im Zeitverlauf nachgewiesen. Einen Einfluss auf die Ausbeute hatten das cT-Stadium, patientenabhängige Risikofaktoren und Geschlecht, sowie die neoadjuvante Therapie. Ein eindeutiger Zusammenhang zwischen der Lymphknotenausbeute und dem fünfjährigen Gesamtüberleben, krankheitsfreien Überleben und der Lokalrezidivrate konnte nicht festgestellt werden. Die Wahrscheinlichkeit mindestens einen befallenen Lymphknoten zu finden stieg jedoch mit der Anzahl entnommener Lymphknoten stetig an, ohne ein Plateau zu erreichen. Daher sollte stets eine größtmögliche Lymphknotenausbeute angestrebt werden, um eine bestmögliche Sicherung der korrekten Tumorklassifikation für die adäquate Therapie und Prognose gewährleisten zu können.

description: Classical secular theory can be a powerful tool to describe the qualitative character of multi-planet systems and offer insight into their histories. The eigenmodes of the secular behavior, rather than current orbital elements, can help identify tidal effects, early planet-planet scattering, and dynamical coupling among the planets, for systems in which mean-motion resonances do not play a role. Although tidal damping can result in aligned major axes after all but one eigenmode have damped away, such alignment may simply be fortuitous. An example of this is 55 Cancri (orbital solution of Fischer et al., 2008) where multiple eigenmodes remain undamped. Various solutions for 55 Cancri are compared, showing differing dynamical groupings, with implications for the coupling of eccentricities and for the partitioning of damping among the planets. Solutions for orbits that include expectations of past tidal evolution with observational data, must take into account which eigenmodes should be damped, rather than expecting particular eccentricities to be near zero. Classical secular theory is only accurate for low eccentricity values, but comparison with other results suggests that it can yield useful qualitative descriptions of behavior even for moderately large eccentricity values, and may have advantages for revealing underlying physical processes and, as large numbers of new systems are discovered, for triage to identify where more comprehensive dynamical studies should have priority.

description: In this paper, a wideband 3.0GHz–5.5GHz Medium Power Amplifier has been  designed and fabricated using 0.8um SiGe BiCMOS process technology. Passive elements such as parallel-branch spiral inductor, metal-insulator-metal (MIM) capacitor and three types of resistors are all integrated in this process. This Medium PA is a two stage design with all matching components and bias circuits integrated on-chip. A P1dB of 16.5dBm has been measured with a power gain of 8.5dB at 4.2GHz with a total current consumption of 130mA from a 2.5 V supply voltage at 25.The measured 3dB bandwidth is 2.5 GHz, which is a very good result for a fully integrated Medium PA. The fabricated circuit occupies a die area of 1.7mm  0.8mm.

description: Approximate Bayesian computation (ABC) methods make use of comparisons between simulated and observed summary statistics to overcome the problem of computationally intractable likelihood functions. As the practical implementation of ABC requires computations based on vectors of summary statistics, rather than full data sets, a central question is how to derive low-dimensional summary statistics from the observed data with minimal loss of information. In this article we provide a comprehensive review and comparison of the performance of the principal methods of dimension reduction proposed in the ABC literature. The methods are split into three nonmutually exclusive classes consisting of best subset selection methods, projection techniques and regularization. In addition, we introduce two new methods of dimension reduction. The first is a best subset selection method based on Akaike and Bayesian information criteria, and the second uses ridge regression as a regularization procedure. We illustrate the performance of these dimension reduction techniques through the analysis of three challenging models and data sets.

Evolution and late stage deformation of the Himalayan metamorphic core, Kanchenjunga region, eastern Nepal
Creators: name: Buckingham, Heather Marie
Publisher: name: University of British Columbia
Year: 2014

description: Understanding the recent history of the Himalayan orogen not only helps elucidates near-surface convergence accommodation processes, but also provides constraints for geometric modification of earlier midcrustal structures. New ⁴⁰Ar/³⁹Ar and fission track (FT) data from the former Himalayan metamorphic core exposed in the Kanchenjunga region of eastern Nepal help constrain the evolution and low temperature uplift history of this portion of the orogen. Within the Lesser Himalayan Sequence (LHS), new apatite FT dates, combined with existing apatite and zircon FT dates from the region, define general younging trends towards the north - up structural section - of ~2.9 to 1.3 Ma and ~6.2 to 4.6 Ma respectively. There appears to be a significant jump in apatite FT dates from 1.3 Ma to 2.4 Ma that is coincident with an abrupt change in existing muscovite ⁴⁰Ar/³⁹Ar ages from the Proterozoic to the Cenozoic. This break in ages is consistent with the mapped location of the Main Central thrust (MCT) fault in the area. In structurally lower rocks in the Greater Himalayan Sequence (GHS), north of the MCT, trends in both muscovite ⁴⁰Ar/³⁹Ar and apatite FT continue to decrease to the north. These trends are interpreted to be consistent with the exhumation and uplift of these rocks associated with the growth of a duplex system within the LHS developed through underplating. Cooling rates across the mapped area indicate fast cooling in the GHS in early to mid Miocene, coupled with very slow cooling in the LHS. In the late Miocene to Pleistocene, cooling rates slow down in the GHS and increase in the LHS, such that they are similar. This is consistent with development of late-stage duplexing within the LHS at this time and the coupled exhumation of the GHS. Biotite ⁴⁰Ar/³⁹Ar dates may indicate a complex history across the study area. Some biotite dates (~24-16 Ma) are older than nearby ²³²Th-²⁰⁸Pb monazite melt crystallization dates (~18-16 Ma). Previous studies have attributed similar old biotite dates to excess argon. It is possible, however, the old biotite dates indicate crystallization along the retrograde path prior to final melt crystallization.
The Dynamics and Metallicity Distribution of the Distant Dwarf Galaxy VV124

description: VV124 (UGC 4879) is an isolated, dwarf irregular/dwarf spheroidal (dIrr/dSph) transition-type galaxy at a distance of 1.36 Mpc. Previous low-resolution spectroscopy yielded inconsistent radial velocities for different components of the galaxy, and photometry hinted at the presence of a stellar disk. In order to quantify the stellar dynamics, we observed individual red giants in VV124 with the Keck/DEIMOS spectrograph. We validated members based on their positions in the color-magnitude diagram, radial velocities, and spectral features. Our sample contains 67 members. The average radial velocity is = -29.1 +/- 1.3 km/s, in agreement with the previous radio measurements of HI gas. The velocity distribution is Gaussian, indicating that VV124 is supported primarily by velocity dispersion inside a radius of 1.5 kpc. Outside that radius, our measurements provide only an upper limit of 8.6 km/s on any rotation in the photometric disk-like feature. The velocity dispersion is sigma_v = 9.4 +/- 1.0 km/s, from which we inferred a mass of M_1/2 = (2.1 +/- 0.2) x 10^7 M_sun and a mass-to-light ratio of (M/L_V)_1/2 = 5.2 +/- 1.1 M_sun/L_sun, both measured within the half-light radius. Thus, VV124 contains dark matter. We also measured the metallicity distribution from neutral iron lines. The average metallicity, = -1.58 +/- 0.06, is consistent with the mass-metallicity relation defined by dwarf spheroidal galaxies. The dynamics and metallicity distribution of VV124 appear similar to dSphs of similar stellar mass.

For that purpose, we develop an ab-initio quantum framework that accounts for the coherent coupling be- tween emitters and surface plasmons and incorporates the presence of dissipation and dephasing. For both a single emitter and a disordered ensemble of emitters, our formalism is able to reveal the key physical mechanisms that explain the reported phenomenology and also to determine the physical parameters that optimize the strong coupling.

description: In this paper, GaN HEMT 1-chip high power amplifiers at S and C bands are presented, which are featured by the cell division configuration. Spurious oscillations, which often occur for large gate periphery microwave transistors, were suppressed by dividing 8 transistor cells in a single chip into 4 blocks each consisting of 2 cells and placing isolation resistors on matching circuits. 120W and 140W output powers were successfully extracted from single chip GaN HEMT transistors with 3.8W/mm and 2.8W/mm power densities at S and C bands, respectively. These are top-level output powers from single chip GaN HEMT transistors over 3GHz.

description: Τα τελευταία χρόνια ο τουρισμός έχει αρχίσει να αλλάζει μορφή, να δημιουργούνται νέες τάσεις που στρέφονται κυρίως σε πιο εναλλακτικές μορφές τουρισμού. Η παρούσα διπλωματική εργασία πραγματεύεται την ανάπτυξη του τουρισμού πολυτελείας στην Ελλάδα, μετά την έλευση μιας από τις χειρότερες υγειονομικές κρίσεις στην ιστορία του τουρισμού, του COVID-19. Βασικός σκοπός της εργασίας είναι η διερεύνηση της ανάπτυξης του τουρισμού και των ξενοδοχείων πολυτελείας, τις νέες αναδυόμενες τάσεις και προοπτικές για το μέλλον, καθώς και τις προτιμήσεις των ταξιδιωτών. Ο τουρισμός πολυτελείας είναι μια ανερχόμενη, κυρίαρχη τάση, στην παγκόσμια τουριστική βιομηχανία, όπου οι ρυθμοί ανάπτυξης αυξάνονται διαρκώς, αποφέροντας σημαντικά έσοδα στην οικονομία της χώρας. Είναι το είδος του τουρισμού που ανέκαμψε γρηγορότερα μετά την πανδημία. Η Ελλάδα θεωρείται ένας από τους πιο δημοφιλείς προορισμούς για διακοπές πολυτελείας όπου παρουσιάζει ανοδική πορεία χρόνο με το χρόνο και αυτό αποδεικνύεται τόσο από τις επιλογές διαμονής που εμπλουτίζονται συνεχώς με πολυτελείς εγκαταστάσεις, όσο και από τις προσφερόμενες υπηρεσίες που αναβαθμίζονται. Σύμφωνα με τα αποτελέσματα της πρωτογενούς ποιοτικής έρευνας που πραγματοποιήθηκε για τους σκοπούς της διπλωματικής εργασίας, η Ελλάδα παρουσιάζει μεγάλο ενδιαφέρον σαν προορισμός και προτιμάται από τουρίστες πολυτελείας, λόγω του φυσικού της κάλλους, της φιλοξενίας και ζεστασιάς των κατοίκων της, του δίπτυχου «ήλιος και θάλασσα». Οι εγκαταστάσεις εκσυγχρονίζονται με τα ξενοδοχεία 5* να πληθαίνουν διαρκώς, ενώ οι διεθνείς ξενοδοχειακές αλυσίδες εισέρχονται δυναμικά στην αγορά. Η πανδημία συνέβαλε στο να ενθαρρύνει τις επιχειρήσεις να εξετάσουν πιο προσεκτικά τη διαδικασία λειτουργίας τους, να επενδύσουν σε νέες τεχνολογίες, ώστε να αναβαθμίσουν τις υπηρεσίες τους. Συνολικά ο τρόπος λειτουργείας του ευρύτερου ξενοδοχειακού κλάδου επαναπροσδιορίστηκε προς το καλύτερο και προσαρμόστηκε σε νέα δεδομένα. Ωστόσο, παρά τη διαρκή ανάπτυξη και αύξηση των πολυτελών ξενοδοχειακών μονάδων, η χώρα υστερεί πολύ σε υποδομές, κυρίως όσων αφορά το οδικό της δίκτυο και τα αεροδρόμια της. Επίσης η έλλειψη σε ανθρώπινο δυναμικό έχει επηρεάσει τη λειτουργία των ξενοδοχείων προς το χειρότερο υποβαθμίζοντας το τουριστικό προϊόν. Η συμβολή των αρμόδιων φορέων, κρίνεται απαραίτητη, προκειμένου να βελτιωθούν οι υποδομές και να καθιερωθεί η Ελλάδα ως παγκόσμιος προορισμός πολυτελείας.

Keldysh effective action theory for universal physics in spin-1/2 Kondo dots

description: We present a theory for the Kondo spin-1/2 effect in strongly correlated quantum dots. The theory is applicable at any temperature and voltage. It is based on a quadratic Keldysh effective action parameterized by a universal function. We provide a general analytical form for the tunneling density of states through this universal function for which we propose a simple microscopic model. We apply our theory to the highly asymmetric Anderson model with $U=\infty$ and describe its strong coupling limit, weak coupling limit and crossover region within a single analytical expression. We compare our results with numerical renormalization group in equilibrium and with a real-time renormalization group out of equilibrium and show that the universal shapes of the linear and differential conductance obtained in our theory and in these theories are very close to each other in a wide range of temperatures and voltages. In particular, as in the real-time renormalization group, we predict that at the Kondo voltage the differential conductance is equal to 2/3 of its maximum.

description: GaAs FET’s are widely used in system such LNA, PA, mixers, frequency multipliers, oscillators and attenuators. Recent works have shown the usefulness of these transistors in the optoelectronics field, as photodetectors or optoelectric mixers.  In this paper an experimental study explores the idea of unifying the detection and mixing of two optical modulated signals at different wavelengths, using a single GaAs FET.  The FET is biased at fixed VGS and VDS and loaded to 50,while two optical modulated signals of different wavelength and frequencies are illuminating the gate of the FET. The results show that the FET can detect both signals and by means of the inherent nonlinearity in the channel of the FET, the sum and difference of both frequencies appear (up and down conversion). Moreover, this type of architecture demonstrates low distortion in contrast to its counterpart (electric and optoelectric mixers) and also, to obtain the same power level for the up and down conversion frequencies, the power level required for the RF and LO signals are much lower than the case of electric and optoelectric mixers.  To our knowledge this is the first time that a single FET is used for detecting and mixing two optical modulated signals at the same time.

description: A K-Band frequency doubler using InGaP HBT is developed, which features high fundamental frequency rejection, flat conversion loss over wide bandwidth, and high saturation output power.  To obtain a balanced signal, a compact on-chip lumped rat-race hybrid is implemented.  The circuit exhibits a measured conversion loss of 4 dB over the output frequencies from 14 to 22 GHz.  The fundamental frequency suppression is better than 20 dB and the second harmonic saturation output power is higher than 7.3 dBm with a miniature chip size of 1 mm  1 mm.

description: In der vorliegenden Arbeit sollte anhand der Anzahl korrekt erinnerter Wörter in einem unerwarteten telefonischen Spätabruf einer Wortlistenaufgabe nach 24 Stunden (Spätabruf 2), verglichen mit denen eines frühen Abrufes (Spätabruf 1), sowie anhand eines Riechtests und eines Gesamtscores zur subjektiven Schlafqualität ein Beitrag zur besseren Abgrenzung subjektiv-kognitiv beeinträchtigter Patienten (SCD) zu Gesunden ohne kognitive Defizite geleistet werden. Alle Teilnehmer erhielten eine neuropsychologische Testung mittels CERAD-Plus Testbatterie, einen Sniffin‘ Sticks-Test und einen Fragebogen zur Selbstevaluation der subjektiven Schlafqualität. Die Probanden (n=113) wurden in eine Kontrollgruppe (KG, n=33) und Gruppen mit subjektiv erlebten kognitiven Defiziten (SCD, n=46) sowie milder kognitiver Beeinträchtigung (MCI, n=34) eingeteilt. Weder anhand des Spätabrufes 2 noch des Spätabrufes 1 konnte zwischen Gesunden und subjektiv-kognitiv beeinträchtigten Personen unterschieden werden. Keines der drei Testinstrumente war alleine in der Lage zwischen Gesunden und subjektiv-kognitiv eingeschränkten Probanden zu unterscheiden. Zur Detektion kognitiver Defizite erscheint der Spätabruf 2 dem Spätabruf 1 jedoch insgesamt überlegen zu sein. Es konnte außerdem eine positive Korrelation zwischen den Abrufleistungen im Spätabruf 2 und der Olfaktion gezeigt werden. Der Spätabruf 2 und der Sniffin‘ Sticks-Test sind gute Instrumente zur Abgrenzung von MCI-Patienten und Gesunden sowie zur Vorhersage des Mini Mental State Ergebnisses als Globalmaß kognitiver Funktionen. Ein lineares Regressionsmodell der Prädiktoren Sniffin‘ Sticks, Spätabruf 2 und PSQI-Gesamtscore kann kognitive Defizite sehr gut vorhersagen.

Assessing quality of life and quality of care for palliative patients in a rural setting using a mixed method approach
Creators: name: Voth, Merel Godelieve
Publisher: name: University of British Columbia
Year: 2014

description: This study explores how individuals living with a life limiting illness experienced and understood their quality of life and quality of care. Currently, few studies have explored the perspectives of palliative patients. The purpose of this study is to provide an in-depth analysis of the experiences of palliative patients and their understanding of quality of life (QoL) and quality of care (QoC) within the context of the Shuswap region of British Columbia (B.C.). This study highlights challenges and strengths of rural palliative care with the goal of informing future policies, programming and services in the rural Shuswap and more broadly. A mixed method approach was used for this study; participants were interviewed twice using a semi-structured interview, completing the McGill Quality of Life Tool prior to the second interview. Interpretive description and descriptive statistics were used for data analysis. The findings of the study indicate that there is a highly inter-connected relationship between the quality of life (QoL) and quality of care (QoC) for the Shuswap rural palliative patients. The findings also indicate that overall the palliative patients living in the rural Shuswap are pleased with their QoL and QoC; however, all participants expressed concerns regarding the coordination of their health care services. Many participants attended multiple health care appointments per week and would like to see their appointments more coordinated. In addition, all of the participants shared their strong desire to remain as independent as possible. Therefore, this study’s findings suggest that care needs to be more coordinated from a patient centred perspective which could result in a higher QoL for patients
Continued Fractions and the Rabi Model

Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Techniques based on continued fractions to compute numerically the spectrum of the quantum Rabi model are reviewed. They are of two essentially different types. In the first case, the spectral condition is implemented using a representation in the infinite-dimensional Bargmann space of analytic functions. This approach is shown to approximate the correct spectrum of the full model if the continued fraction is truncated at sufficiently high order. In the second case, one considers the limit of a sequence of models defined in finite-dimensional state spaces. Contrary to the first, the second approach is ambiguous and can be justified only through recourse to the analyticity argument from the first method.

description: A dc-to-50-GHz SPDT switch in standard bulk 0.18-m CMOS process is demonstrated in this paper. In order to extend the operation frequency, the traveling-wave circuit topology is utilized. The switch achieves a measured insertion loss of less than 6 dB, a measured isolation of better than 38 dB from dc to 50 GHz. The measured input P1dB of 17.4 dBm at 5.8 GHz and 19.6 dBm at 40 GHz is attained. The chip size is only 0.5 x 0.5 mm2. To our knowledge, this work is the first CMOS switch operating from dc to millimeter-wave frequency with a miniature chip size.

description: Densfrakturen treten häufig bei älteren Menschen auf. Mit zunehmendem Alter und aufgrund der medizinischen Entwicklung steigt die Zahl der Densfrakturen. In der Literatur bleibt die Standardversorgung der Densfrakturen umstritten. Für die Häufigkeit der sekundären Instabilität nach ventraler Versorgung der Densfrakturen mittels einer oder zweier Doppelgewindeschrauben besteht nur wenig Evidenz. Im Zeitraum von 2002 bis 2016 wurden 198 Patienten (n = 198) mit Densfrakturen in der neurochirurgischen Klinik des Universitätsklinikums Magdeburg behandelt. Dabei wurden 151 Patienten (n = 151) von ventral versorgt. In dieser retrospektiven Studie werden die Langzeitergebnisse hinsichtlich der Stabilitäts-/Instabilitätsrate nach der ventralen Versorgung der Densfrakturen dargestellt.

description: A stochastic gravitational wave background (SGWB) would gravitationally lens the cosmic microwave background (CMB) photons. We find that the lensing due to gravitational waves(GW) is more efficient as compared to lensing due to scalar density perturbations. Though the effect of lensing due to GW is found to effect all the four CMB power spectra, its effect is most prominently seen in the CMB polarization power spectra. This suggests that the measurements of the CMB angular power spectra could be used to constraining the energy density ($Ω_{GW}$) of the SGBW. In our analysis we find that the most stringent constraints on $Ω_{GW}$ are due to measurements of the angular power spectra of CMB temperature anisotropies. We show that in the future it will be possible to place more stringent bounds on $Ω_{GW}$ using improved upper limits or detections of the angular power spectra of the B-modes of CMB polarization at large multipoles.

description: This paper presents a trial fabricated GaAs monolithic anti-series varactor pair. Its second-order and third-order harmonic distortions, which are generated from the nonlinearity of capacitance-voltage characteristics, are investigated experimentally and numerically. Compared to the case of a single varactor, the distortions of measurement and simulation are suppressed by about 25 dB and 45 dB for the second-order harmonic, and 3 dB and 10 dB for the third-order harmonic, respectively.
