Nomarski imaging interferometry to measure the displacement field of MEMS

description: We propose to use a Nomarski imaging interferometer to measure the out-of-plane displacement field of MEMS. It is shown that the measured optical phase arises both from height and slope gradients. Using four integrating buckets a more efficient approach to unwrap the measured phase is presented, thus making the method well suited for highly curved objects. Slope and height effects are then decoupled by expanding the displacement field on a functions basis, and the inverse transformation is applied to get a displacement field from a measure of the optical phase map change with a mechanical loading. A measurement reproducibility of about 10 pm is achieved, and typical results are shown on a microcantilever under thermal actuation, thereby proving the ability of such a set-up to provide a reliable full-field kinematic measurement without surface modification.

description: Using the quasiclassical Green's function formalism, we study the influence of the odd-frequency spin-triplet superconductivity on the local density of states (LDOS) in a diffusive ferromagnet (DF) attached to a superconductor. Various possible symmetry classes in a superconductor are considered which are consistent with the Pauli's principle: even-frequency spin-singlet even-parity (ESE) state, even-frequency spin-triplet odd-parity (ETO) state, odd-frequency spin-triplet even-parity (OTE) state and odd-frequency spin-singlet odd-parity (OSO) state. For each of these states, the pairing state in DF is studied. Particular attention is paid to the study of spin-singlet s-wave and spin-triplet p-wave superconductors as the examples of ESE and ETO superconductors. For spin-singlet case the magnitude of the OTE component of the pair amplitude is enhanced with the increase of the exchange field in DF. When the OTE component is dominant at low energy, the resulting LDOS in DF has a zero energy peak (ZEP). On the other hand, in DF / spin-triplet p-wave superconductor junctions LDOS has a ZEP in the absence of the exchange field, where only the OTE paring state exists. With the increase of the exchange field, the ESE component of the pair amplitude induced in DF is enhanced. Then, the resulting LDOS has a ZEP splitting. We demonstrate that the appearance of the dominant OTE component of the pair amplitude is the physical reason of the emergence of the ZEP of LDOS.

description: We show how to carry out the gauging of the Poisson sigma model in an AKSZ inspired formulation by coupling it to the a generalization of the Weil model worked out in ref. arXiv:0706.1289 [hep-th]. We call the resulting gauged field theory, Poisson--Weil sigma model. We study the BV cohomology of the model and show its relation to Hamiltonian basic and equivariant Poisson cohomology. As an application, we carry out the gauge fixing of the pure Weil model and of the Poisson--Weil model. In the first case, we obtain the 2--dimensional version of Donaldson--Witten topological gauge theory, describing the moduli space of flat connections on a closed surface. In the second case, we recover the gauged A topological sigma model worked out by Baptista describing the moduli space of solutions of the so--called vortex equations.

description: A new theory describing the interaction between atoms and a conductor with small densities of current carriers is presented. The theory takes into account the penetration of the static component of the thermally fluctuating field in the conductor and generalizes the Lifshitz theory in the presence of a spatial dispersion. The equation obtained for the force describes the continuous crossover between the Lifshitz results for dielectrics and metals.

description: Type Ia supernovae (SNe Ia) are believed to be a thermonuclear explosion of a white dwarf, but the mass of their progenitors is still an open problem. In near-Chandrasekhar-mass (near-M_Ch) models of SNe Ia, the central density reaches >10^9 g cm^{-3}. The electron chemical potential becomes higher than the Q-values of electron capture (EC) transitions between fp-shell nuclei, so a portion of the available electrons is captured by iron group elements and thus neutron-rich isotopes are formed. Since EC reaction rates are sensitive to the density, the degree of neutronization is a key to distinguish near- and sub-M_Ch models. In order to compare observations and theoretical models, an accurate treatment of EC reactions is necessary. In previous theoretical works, however, effects of electron screening on ECs are ignored. Screening lowers EC rates and thus leads to a higher electron fraction. We implement electron screening on ECs to calculate explosive SN Ia nucleosynthesis in a near-M_Ch single degenerate model. It is found that some of neutron-rich nuclear abundances, namely those of 46,48Ca, 50Ti, 54Cr, 58Fe, 64Ni and 67,70Zn, decrease when screening effects on ECs are considered. Of these, 50Ti, 54Cr and 58Fe are particularly interesting because a significant portion of the solar abundance of these nuclei is presumed to originate from SNe Ia. We conclude that implementing the screening effect on ECs in modern SN Ia models is desirable to precisely calculate abundances of neutron-rich nuclides.

description: Η Chiapas αποτελεί περίπτωση μιας περιοχής, όπου οι τρόποι κοινωνικής διάδρασης που βασίζονται σε αποικιοκρατικά ιδεολογικά μοντέλα έχουν μετασχηματιστεί σε προβληματικές για την τουριστική ανάπτυξη. Η εξέγερση του EZLN μπορεί να είχε αρχικά αρνητικό αντίκτυπο για τον τουρισμό, ωστόσο η ανταπόκριση της τουριστικής βιομηχανίας αποτέλεσε ένα παράδοξο φαινόμενο, επινοώντας νέες στρατηγικές προκειμένου να μετατρέψει τα αρνητικά αποτελέσματα σε θετικά. Οι ενέργειες αυτές ευνοήθηκαν από ένα νέο είδος τουρίστα, τον πολιτικοποιημένο ή μη-τουρίστα ή «ζαπατουρίστα» και η οργάνωση του «ζαπατουρισμού» έγινε μέσα από δίκτυα, ευέλικτα και αυτο-οργανωμένα σ’ ένα επίπεδο μικρο-οικονομίας. Η πολιτική πραγματικότητα της ζαπατιστικής εξέγερσης και η παγκόσμια απήχηση που απέκτησε, διαμορφώνοντας την ιδεολογία του νεοζαπατισμού, ήταν ο σημαντικότερος παράγοντας που καθόρισε την επιτυχία των κοινωνικών αυτών δικτύων. Η τουριστική βιομηχανία κλήθηκε να ανταποκριθεί μεταμορφώνοντας την εικόνα του «ιθαγενούς» και εμπορευματοποιώντας την πολιτική αστάθεια στην περιοχή.
description: Chiapas is the case of a place, where the forms of social interaction based on colonial models of belief, have been transformed into problematical for the development of tourism. The EZLN uprising may originally have had a negative impact on tourism, but the tourist industry responded paradoxically, inventing new strategies in order to transform the negative results into positive oves. These actions were favoured by a new type of tourist, the politicized or non-tourist or “zapatourist” and “zapatourismo” was organized through networks, which were flexible and self-managed on a micro-economical level. The political reality of the zapatista uprising and the global impact it obtained, forming the ideology of neozapatismo, was the most important factor designating the success of these social networks. The tourist industry was called in response, transforming the “indigenous” image and commercializing the political instability in the area.

description: We calculate Lambda alpha, Sigma alpha and Xi alpha potentials from the nuclear-matter G-matrices of the SU6 quark-model baryon-baryon interaction. The alpha-cluster wave function is assumed to be a simple harmonic-oscillator shell-model wave function. A new method is proposed to derive the direct and knock-on terms of the interaction Born kernel from the hyperon-nucleon G-matrices, with explicit treatments of the nonlocality and the center-of-mass motion between the hyperon and alpha. We find that the SU6 quark-model baryon-baryon interactions, FSS and fss2, yield a reasonable bound-state energy for 5 He Lambda, -3.18 -- -3.62 MeV, in spite of the fact that they give relatively large depths for the Lambda single-particle potentials, 46 -- 48 MeV, in symmetric nuclear matter. An equivalent local potential derived from the Wigner transform of the nonlocal Lambda alpha kernel shows a strong energy dependence for the incident Lambda-particle, indicating the importance of the strangeness-exchange process in the original hyperon-nucleon interaction. The Sigma alpha and Xi alpha potentials are repulsive with the attractive isospin I=1/2 (Sigma alpha) and I=0 (Xi alpha) components and the repulsive I=3/2 (Sigma alpha) and I=1 (Xi alpha) components.

description: Virtual meetings are critical for remote work because of the need for synchronous collaboration in the absence of in-person interactions. In-meeting multitasking is closely linked to people's productivity and wellbeing. However, we currently have limited understanding of multitasking in remote meetings and its potential impact. In this paper, we present what we believe is the most comprehensive study of remote meeting multitasking behavior through an analysis of a large-scale telemetry dataset collected from February to May 2020 of U.S. Microsoft employees and a 715-person diary study. Our results demonstrate that intrinsic meeting characteristics such as size, length, time, and type, significantly correlate with the extent to which people multitask, and multitasking can lead to both positive and negative outcomes. Our findings suggest important best-practice guidelines for remote meetings (e.g., avoid important meetings in the morning) and design implications for productivity tools (e.g., support positive remote multitasking).

description: Lennard (2013) [Fingerprint identification: how far have we come? Aus J Forensic Sci. doi:10.1080/00450618.2012.752037] proposes that the numeric output of statistical models should not be presented in court (except "if necessary" / "if required"). Instead he argues in favour of an "expert opinion" which may be informed by a statistical model but which is not itself the output of a statistical model. We argue that his proposed procedure lacks the transparency, the ease of testing of validity and reliability, and the relative robustness to cognitive bias that are the strengths of a likelihood-ratio approach based on relevant data, quantitative measurements, and statistical models, and that the latter is therefore preferable.
Understanding the effect of pathogenic variants on protein function to guide drug discovery

Publisher: name: F1000 Research Limited
Year: 2019

description: The mechanistic details relating to protein function are scattered across multiple resources making a unified mapping across this data difficult and time consuming. We have set out to design and build an integrative layer to map the diverse protein function data available in EMBL-EBI resources onto a reference protein entity/sequence. By capturing functional mechanisms, annotating genetic variants and post-translational modifications in protein sequences, we aim at facilitating the understanding of the role of potential drug targets in disease and the role of pathogenic mutations in this process. We have identified opportunities for additional mapping among protein resources at EMBL-EBI and the need to enhance data coverage in targeted disease areas. We are currently collecting use cases scenarios and creating mockups for this information to be available on the Open Targets Platform at https://www.targetvalidation.org. Data will be provided in an intuitive and easy-to-visualise manner to help drug discovery scientists in the systematic prioritisation of drug targets. This approach will be designed to be extensible and scalable to enable the inclusion of additional protein function resources to encompass new data from Open Targets and elsewhere.

description: Recent experiments at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) have indicated that hadrons containing strange quarks produced in non-central heavy ion collisions can be polarized. We investigate in detail the coupling of spin and vorticity for electrically neutral, massive vector bosons using the Proca equation, and provide the nonrelativistic reduction of the field equations via a single Foldy--Wouthuysen transformation. We find that the resulting Hamiltonian is not-Hermitian, but ${\cal PT}$ invariant, and involves a spin dependent term $\textstyle{\frac{1}{2}} s_z \hbar ω$ to leading order in vorticity. We also calculate further relativistic and quantum corrections to the Hamiltonian.

description: We derive a general expression for the cumulant generating function (CGF) of non-Markovian quantum stochastic transport processes. The long-time limit of the CGF is determined by a single dominating pole of the resolvent of the memory kernel from which we extract the zero-frequency cumulants of the current using a recursive scheme. The finite-frequency noise is expressed not only in terms of the resolvent, but also initial system-environment correlations. As an illustrative example we consider electron transport through a dissipative double quantum dot for which we study the effects of dissipation on the zero-frequency cumulants of high orders and the finite-frequency noise.

description: Monte Carlo event generators are a critical tool for the interpretation of data obtained by neutrino experiments. Several modern event generators are available which are well-suited to the GeV energy scale used in studies of accelerator neutrinos. However, theoretical modeling differences make their immediate application to lower energies difficult. In this paper, I present a new event generator, MARLEY, which is designed to better address the simulation needs of the low-energy (tens of MeV and below) neutrino community. The code is written in C++14 with an optional interface to the popular ROOT data analysis framework. The current release of MARLEY (version 1.2.0) emphasizes simulations of the reaction $^{40}$Ar$(ν_e, e^{-})^{40}$K$^{*}$ but is extensible to other channels with suitable user input. This paper provides detailed documentation of MARLEY's implementation and usage, including guidance on how generated events may be analyzed and how MARLEY may be interfaced with external codes such as Geant4. Further information about MARLEY is available on the official website at http://www.marleygen.org.

Math penpals as a context for learning to teach: a study of preservice teachers' learning
Creators: name: Crespo, Sandra
Publisher: name: University of British Columbia
Year: 2009

description: This study explores preservice teachers' learning to teach mathematics in the context of an innovative version of the mathematics methods courses typically offered at UBC. Thirteen preservice teachers engaged in a math letter writing exchange with Grade 4 students are the focus of this study. This math penpal experience was meant to provide a "laboratory setting" for preservice teachers to try out and investigate the ideas discussed during methods classes. Interactions with students, in turn, served as the focus of further class discussions and reflective journal writing. Two research questions were investigated: (1) What were preservice teachers learning through their math penpal investigations; and (2) What factors influenced their learning? Preservice teachers' written records (math letters, journals, and case reports) were the main sources of data used to address these questions. My perspectives as a participant, teacher, and researcher were used to guide and inform my analysis of this data. An analytical framework was constructed based on preservice teachers' "pedagogical puzzles" (issues and challenges faced and deliberated on). These puzzles related to their problem posing, interpreting, and responding practices. This framework was used to explore patterns and changes in preservice teachers' views and practices. Learning themes discussed include: learning to broaden goals and expectations of problems; learning to see and construct meaning from students' work, and learning to question and revise claims about students' mathematical attitudes and abilities; learning to recognize and interrogate hidden messages in their discourse, and learning to respond differently. Factors found to be associated with preservice teachers' learning include: (a) interactive experiences with students, (b) engagement in collaborative explorations of problems and comparable students' work, and (c) the opportunity to revisit and reinterpret their experiences with students in multiple occasions. Implications for the research and practice of mathematics teacher education are discussed in relation to: (a) preservice teachers' learning of mathematics and mathematical pedagogy, (b) learning in courserelated field experiences, and (c) learning to reflect and write about teaching and learning.

Απομακρύνθηκε από την κλασική πολιτική σκέψη του Πλάτωνα και του Αριστοτέλη, απορρίπτοντας το πρότυπο των φανταστικών ηγεμονικών που είχε κληρονομήσει ως πολιτική σκέψη από τους παλαιότερους του πολιτικούς φιλόσοφους και στοχαστές.

description: Nichollo Machiavelli is one of the most exciting but yet amibuous personalities of western thought, political and philosophical. Away from the classical political thought of Plato and Aristotle, has rejected the ideal pattern of traditional governemnt and ideal republic. He analyzes the real circumstance of the practice of a state and discusses about the real politic, the real life of a civilian. He succeeds in finding the balance between the state and its people. The civilians are the state. He is most concerned in the matter of freedom and how we can be actual free within a state. For him the idea of freedom should never be granded, but the civilians and the state should always be awake in order to protect it

description: We analyze the WW scattering in scenarios of dynamical electroweak symmetry breaking of walking technicolor type. We show that in these theories there are regions of the parameters space allowed by the electroweak precision data, in which unitarity violation is delayed at tree level up to around 3-4 TeV without the inclusion of any sub-TeV resonances.

description: Η παρούσα εργασία αναφέρεται σε αλυσίδες με μακράς διάρκειας συσχετίσεις (long range correlations) με εφαρμογή στην αλυσίδα DNA. Η αλυσίδα DNA περιγράφεται μέσω διωνυμικών Μαρκοβιανών αλυσίδων Ν-τάξης. Αρχικά παρουσιάζεται το μοντέλο με δύο παραμέτρους, το μήκος μνήμης Ν και την παράμετρο συσχέτισης μ, οι οποίες συνθέτουν τη δεσμευμένη πιθανότητα, όπου Υπολογίζεται επίσης η συνάρτηση πιθανότητας η οποία δηλώνει την πιθανότητα μια λέξη μεγέθους L να έχει k μονάδες, καθώς και η διασπορά του πλήθους των μονάδων για τις περιπτώσεις και Οι μακράς διάρκειας συσχετίσεις εμφανίζονται όταν η διασπορά δεν παρουσιάζει γραμμικότητα ως συνάρτηση του μήκους L. Στη συνέχεια υπολογίζονται οι πιθανότητες εμφάνισης και αν και αντίστοιχα, καθώς και η πιθανότητα μιας λέξης σε αντιμεταθετική αλυσίδα. Αποδεικνύεται η ισοδυναμία των Μαρκοβιανών αλυσίδων και των δίπλευρων (two-sided) αλυσίδων και αναπτύσσεται η έννοια της ισοτροπίας (isotropy) των Μαρκοβιανών και αντιμεταθετικών Μαρκοβιανών αλυσίδων.

Τέλος, γίνεται διερεύνηση της πρότασης ότι σε μια λέξη σημασία έχει το πλήθος των μονάδων και όχι η διάταξή τους.
description: This work is referred to chains with long range correlations for application in DNA texts. The DNA chain is described through binary N-step Markov chains. At first the model is presented with two parameters, the memory length N and the correlation parameter μ which compose the conditional probability, with Moreover, the probability function of the words of definite length L and k unities, and the respective variance are obtained for and . When variance doesn’t exhibit linear dependence on L, long range correlations exist. Then, probabilities and are defined for and respectively and the probability of a word’s appearance in a permutative Markov chain. The equivalence of Markov’s symbolic sequences with the two-sided chains is proved and the isotropy of Markov and permutative Markov chains is established. In last section, the existence of long range correlations in Arabidopsis Thaliana is studied and we try to evaluate the memory length N. Finally, we investigate the statement that the probability depends only on the number k of unities, for

description: We construct a new class of charged rotating solutions of $(n+1)$-dimensional Einstein-Born-Infeld gravity with cylindrical or toroidal horizons in the presence of cosmological constant and investigate their properties. These solutions are asymptotically (anti)-de Sitter and reduce to the solutions of Einstein-Maxwell gravity as the Born-Infeld parameters goes to infinity. We find that these solutions can represent black branes, with inner and outer event horizons, an extreme black brane or a naked singularity provided the parameters of the solutions are chosen suitably. We compute temperature, mass, angular momentum, entropy, charge and electric potential of the black brane solutions. We obtain a Smarr-type formula and show that these quantities satisfy the first law of thermodynamics. We also perform a stability analysis by computing the heat capacity and the determinant of Hessian matrix of mass with respect to its thermodynamic variables in both the canonical and the grand-canonical ensembles, and show that the system is thermally stable in the whole phase space.

description: We consider a three dimensional spatial network, where $N$ nodes are randomly distributed within a cube $L\times L\times L$. Each two nodes are connected if their mutual distance does not excess a given cutoff $a$. We analyse numerically the probability distribution of the critical density $ρ_c=N(a_c/L)^3$, where one or more nodes become separated; $ρ_c$ is found to increase with $N$ as $N^{0.105}$, where $N$ is between 20 and 300. The results can be useful for a design of protocols to control sets of wearable sensors.

description: Characterizing the noise in the set of gate operations that form the building blocks of a quantum computational device is a necessity for assessing the quality of the device. Here, we introduce randomized linear gate set tomography, an easy-to-implement gate set tomography procedure that combines the idea of state-preparation-and-measurement-error-free characterization of standard gate set tomography with no-design randomized tomographic circuits and computational ease brought about by an appropriate linear approximation. We demonstrate the performance of our scheme through simulated examples as well as experiments done on the IBM Quantum Experience Platform. In each case, we see that the performance of our procedure is comparable with that of standard gateset tomography, while requiring no complicated tomographic circuit design and taking much less computational time in deducing the estimate of the noise parameters. This allows for straightforward on-the-fly characterization of the gate operations in an experiment.

Description
Tatia jaracatia is clearly recognizable from its congeners by its colour pattern showing dark flanks with large whitish or pale yellow rounded or oval dots (figs. 1-3). This colour pattern distinguishes this species from T. neivai, the other species inhabiting freshwater environments of Argentina. Morphometric data are presented in table 1.
Habitat
The depth of arroyo Deseado was variable, averaging about 80 cm. The bottom was composed of mud, sand and mainly gravel. The stream has falls and pools with clear, rapidly flowing water. The pools had scarce submerged vegetation. One specimen was collected above a fall and the other in a large pool below (fig. 4).
Distribution
Tatia jaracatia is restricted to the río Iguazú basin above the Iguazú falls (Pavanelli & Bifi, 2009). The specimens collected herein come from arroyo Deseado in Misiones Province (fig. 7).

description: We investigate the phase structure of an asymmetric fermion superfluid with inter- and intra-species pairings. The introduction of the intra-species pairing mechanism in canonical ensemble changes significantly the phase diagram and brings in a new state with coexisting inter- and intra-species pairings. Different from the case with only inter-species pairing, all the fermion excitations are fully gapped in the region with intra-species pairing.

description: Two-dimensional (2D) tungsten disulfide (WS$_2$), tungsten diselenide (WSe$_2$), and tungsten ditelluride (WTe$_2$) draw increasing attention due to their attractive properties deriving from the heavy tungsten and chalcogenide atoms, but their mechanical properties are still mostly unknown. Here, we determine the intrinsic and air-aged mechanical properties of mono-, bi-, and trilayer (1-3L) WS$_2$, WSe$_2$ and WTe$_2$ using a complementary suite of experiments and theoretical calculations. High-quality 1L WS$_2$ has the highest Young's modulus (302.4+-24.1 GPa) and strength (47.0+-8.6 GPa) of the entire family, overpassing those of 1L WSe$_2$ (258.6+-38.3 and 38.0+-6.0 GPa, respectively) and WTe$_2$ (149.1+-9.4 and 6.4+-3.3 GPa, respectively). However, the elasticity and strength of WS$_2$ decrease most dramatically with increased thickness among the three materials. We interpret the phenomenon by the different tendencies for interlayer sliding in equilibrium state and under in-plane strain and out-of-plane compression conditions in the indentation process, revealed by finite element method (FEM) and density functional theory (DFT) calculations including van der Waals (vdW) interactions. We also demonstrate that the mechanical properties of the high-quality 1-3L WS$_2$ and WSe$_2$ are largely stable in the air for up to 20 weeks. Intriguingly, the 1-3L WSe$_2$ shows increased modulus and strength values with aging in the air. This is ascribed to oxygen doping, which reinforces the structure. The present study will facilitate the design and use of 2D tungsten dichalcogenides in applications, such as strain engineering and flexible field-effect transistors (FETs).
