description: Maximizing the ratio between Kitaev and residual Heisenberg interactions is a major goal in nowadays research on Kitaev-Heisenberg quantum magnets. Here we investigate Kitaev-Heisenberg exchange in a recently discovered crystalline phase of RuCl$_3$ under presure -- it displays unusually high symmetry, with only one type of Ru-Ru links, and uniform Ru-Cl-Ru bond angles of $\approx$93$^{\circ}$. By quantum chemical calculations in this particular honeycomb-lattice setting we find a very small $J$, which yields a $K/J$ ratio as large as $\sim$100. Interestingly, we also find that this is associated with vanishingly small $d$-shell trigonal splittings, i.\,e., minimal departure from ideal $j_{\mathrm{eff}}\!=\!1/2$ moments. This reconfirms RuCl$_3$ as a most promising platform for materializing the much sought-after Kitaev spin-liquid phase and stimulates further experiments under strain and pressure.
title: Seriousness of Dodder in Production of Alfalfa Seed in Millard County
Creators: name: Warner, Lloyd Claude
Publisher: name: Utah State University
Year: 1961

description: Dodder is the common name for the group of plants in the genus Cuscuta. It is a serious weed in nearly all the legume seed producing areas of southern and western United States (5). Dodder is of major economic importance in the production of alfalfa, lespedeza, clover, and of less importance in such crops as flax, onions, sugar beets, and some ornamentals.
Comparative study of inter and intralocus recombination in Drosophila
Creators: name: Scholefield, Dorothy Jane Stuart
Publisher: name: University of British Columbia
Year: 2011

description: The effect of different treatments on crossing over between and within genes at the tip of the X chromosome of Drosophila melanogaster was studied to determine whether exchange in the two regions occurs by different mechanisms. In response to autosomal inversions, ɣ -radiation, and heat shock, crossing over of both types was altered in the same direction and to a comparable extent. This would be expected if there were only one crossover mechanism involved. There was some difference in response of interlocus and intralocus crossing over after mitomycin C injection but, since the effect on interlocus crossing over in two separate regions was not consistent, the significance of this result is questionable. Although double crossing over involving the two interlocus regions was very rare doubles involving an inter and an intralocus region were recovered. The association of exchanges within a gene with a crossover between genes might indicate that there are two noninterfering mechanisms, or that multiple exchanges occur in short effectively paired regions. A further experiment designed to detect switch regions is outlined.

description: Blended learning is not a new concept; recently, there has been a renewed focus on this learning strategy, both in the education and corporate sectors. Although the definition of blended learning is somewhat inchoate, it is generally described as an environment that includes the use of different modes of teaching and learning. Blended learning holds particular promise for developing countries because it can make availability of resources, regional, and international educational institutions. The perspective we adopt in this paper, where we aim to take a realistic look at the potential of blended learning in developing countries, giving consideration to the various possibilities and most importantly, to the accessibility of technology both today and in the future.
Eisenstein series, $p$-adic modular functions, and overconvergence, II

description: Let $p$ be a prime number. Continuing and extending our previous paper with the same title, we prove explicit rates of overconvergence for modular functions of the form $\frac{E_k^{\ast}}{V(E_k^{\ast})}$ where $E_k^{\ast}$ is a classical, normalized Eisenstein series on $Γ_0(p)$ and $V$ the $p$-adic Frobenius operator. In particular, we extend our previous paper to the primes $2$ and $3$. For these primes our main theorem improves somewhat upon earlier results by Emerton, Buzzard and Kilford, and Roe. We include a detailed discussion of those earlier results as seen from our perspective. We also give some improvements to our earlier paper for primes $p\ge 5$.
 Apart from establishing these improvements, our main purpose here is also to show that all of these results can be obtained by a uniform method, i.e., a method where the main points in the argumentation is the same for all primes.
 We illustrate the results by some numerical examples.

description: This paper describes a structural analysis of the CAD model three versions fixators Sarafix which is to explore the possibility of introducing composite materials in the construction of the connecting rod fixators comparing values of displacement and stiffness at characteristic structure points. Namely, we have investigated the constructional performance of fixators Sarafix with a connecting rod formed from three different composite materials, the same matrix (epoxy resin) with three different types of fibers (E glass, kevlar 49 and carbonM55J). The results of the structural analysis fixators Sarafix with a connecting rod made of composite materials are compared with the results of tubular connecting rod fixators made of stainless steel. After comparing the results, from the aspect of stiffness, we gave the final considerations about composite material which provides an adequate substitution for the existing material.

description: We measure the large-scale clustering of MgII λλ2796,2803 absorbers with respect to a population of luminous red galaxies (LRGs) at z \sim 0.5. From the cross-correlation measurements between MgII absorbers and LRGs, we calculate the mean bias of the dark matter halos in which the absorbers reside. We investigate systematic uncertainties in the clustering measurements due to the sample selection of LRGs and due to uncertainties in photometric redshifts. First, we compare the cross-correlation amplitudes determined using a it flux-limited LRG sample and a volume-limited one. The comparison shows that the relative halo bias of MgII absorbers using a flux-limited LRG sample can be overestimated by as much as \approx 20%. Next, we assess the systematic uncertainty due to photometric redshift errors using a mock galaxy catalog with added redshift uncertainties comparable to the data. We show that the relative clustering amplitude measured without accounting for photometric redshift uncertainties is overestimated by \approx 10%. After accounting for these two main uncertainties, we find a 1-σanti-correlation between mean halo bias and absorber strength that translates into a 1-σanti-correlation between mean galaxy mass and W_r(2796). The results indicate that a significant fraction of the MgII absorber population of W_r(2796)=1-1.5 Åare found in group-size dark matter halos of log M_h < 13.4, whereas absorbers of W_r(2796)>1.5 Åare seen in halos of log M_h <12.7. A larger dataset would improve the precision of the clustering measurements and the relationship between W_r and halo mass. Finally, the strong clustering of MgII absorbers down to \sim 0.3 h^{-1} Mpc indicates the presence of cool gas inside the virial radii of the halos hosting the LRGs.

description: Intellectual stimulation is one of the manifestations of transformational leadership. Intellectual stimulation is the aspect of leadership where the leader encourages teams’ ingenuity, creativity and innovative thinking, urging them to keenly question the status quo in order to make discoveries. The purpose of this study was to explore the Influence of intellectual stimulation and conflict resolution on projects implementation. The objective was to determine the Influence of intellectual stimulation and conflict resolution on projects implementation. The study used Expost facto design. Multifactor leadership Questionnaire, Thomas Kilman Instruments, Interview, and documentary analysis were used as tools for data collection. The probability sampling used was stratified and simple random sampling technique. Data was analyzed both quantitatively and qualitatively. Multiple linear regression analysis was used as tool of analysis to test for significance in the hypothesis. One hypothesis was formulated and subsequently tested in the study in order to establish the influence of conflict resolution thereof, in hypothesis H1,( H0: The strength of the relationship between intellectual stimulation and implementation of CDF construction projects does not depend on conflict resolution.), it was concluded that the strength of the relationship between intellectual stimulation and implementation of CDF construction projects depends on conflict resolution(P=0.001˂P=0.05),using multiple linear regression analysis the following results were obtained- F value of 7.788,d.f (2,59) and (P-value 0.00˂P= 0.05) significance level which was statistically significant. It was therefore concluded that there is a regression relationship between intellectual stimulation with conflict resolution and implementation of CDF projects. It is therefore recommended that accredited MLQ coaching is desirable, coaching from the systems’ psychodynamic stance could equip the leader in terms of awareness of diversity dynamics and conflict management.

description: In the relatively low lying delta area west of Ogden, Utah several thousand acres of potentially productive lands have been seriously affected by the accumulation of soluble salts and the associated condition of excessive exchangeable sodium. As a part of the Weber Basin Project, much of this large area of undeveloped or only partially developed land is proposed for irrigation. Successful irrigation of these salt-affected lands, however, is dependent upon their reclamation and improvement.

description: Itinerant electrons in a two-dimensional Kagome lattice form a Dirac semi-metal, similar to graphene. When lattice and spin symmetries are broken by various periodic perturbations this semi-metal is shown to spawn interesting non-magnetic insulating phases. These include a two-dimensional topological insulator with a non-trivial Z_2 invariant and robust gapless edge states, as well as dimerized and trimerized `Kekule' insulators. The latter two are topologically trivial but the Kekule phase possesses a complex order parameter with fractionally charged vortex excitations. A charge density wave is shown to couple to the Dirac fermions as an effective axial gauge field.

Effect of random environment on kinetic roughening: Kardar-Parisi-Zhang model with a static noise coupled to the Navier-Stokes equation

description: Kinetic roughening of a randomly growing surface can be modelled by the Kardar-Parisi-Zhang equation with a time-independent (``spatially quenched'' or ``columnar'') random noise. In this paper, we use the field-theoretic renormalization group approach to investigate how randomly moving medium affects the kinetic roughening. The medium is described by the stochastic differential Navier-Stokes equation for incompressible viscous fluid with an external stirring force. We find that the action functional for the full stochastic problem should be extended to be renormalizable: a new nonlinearity must be introduced. Moreover, in order to correctly couple the scalar and velocity fields, a new dimensionless parameter must be introduced as a factor in the covariant derivative of the scalar field. The resulting action functional involves four coupling constants and a dimensionless ratio of kinematic coefficients. The one-loop calculation (the leading order of the expansion in $\varepsilon=4-d$ with $d$ being the space dimension) shows that the renormalization group equations in the five-dimensional space of those parameters reveal a curve of fixed points that involves an infrared attractive segment for $\varepsilon>0$.

description: We studied the thermodynamics of the one-dimensional J1-J2 spin-1/2 Heisenberg chain for ferromagnetic nearest-neighbor bonds J1 < 0 and frustrating antiferromagnetic next-nearest-neighbor bonds J1 > 0 using full diagonalization of finite rings and a second-order Green-function formalism. Thereby we focus on J2 < |J1|/4 where the ground state is still ferromagnetic, but the frustration influences the thermodynamic properties. We found that their critical indices are not changed by J2. The analysis of the low-temperature behavior of the susceptibility chi leads to the conclusion that this behavior changes from chi \propto T^{-2} at J2 < |J1|/4 to chi \propto T^{-3/2} at the quantum-critical point J2=|J1|/4. Another effect of the frustration is the appearance of an extra low-T maximum in the specific heat C_v(T) for J2 \gtrsim |J1|/8, indicating its strong influence on the low-energy spectrum.

description: Solar coronal waves frequently appear as bright disturbances that propagate globally from the eruption center in the solar atmosphere, just like the tsunamis in the ocean on Earth. Theoretically, coronal waves can sweep over the underlying chromosphere and leave an imprint in the form of Moreton wave, due to the enhanced pressure beneath their coronal wavefront. Despite the frequent observations of coronal waves, their counterparts in the chromosphere are rarely detected. Why the chromosphere rarely bears the imprints of solar tsunamis remained a mystery since their discovery three decades ago. To resolve this question, all coronal waves and associated Moreton waves in the last decade have been initially surveyed, though the detection of Moreton waves could be hampered by utilising the low-quality H$α$ data from Global Oscillations Network Group. Here, we present 8 cases (including 5 in Appendix) of the coexistence of coronal and Moreton waves in inclined eruptions where it is argued that the extreme inclination is key to providing an answer to address the question. For all these events, the lowest part of the coronal wavefront near the solar surface appears very bright, and the simultaneous disturbances in the solar transition region and the chromosphere predominantly occur beneath the bright segment. Therefore, evidenced by observations, we propose a scenario for the excitation mechanism of the coronal-Moreton waves in highly inclined eruptions, in which the lowest part of a coronal wave can effectively disturb the chromosphere even for a weak (e.g., B-class) solar flare.

description: Taust. Patsientide funktsionaalse võimekuse mõõtmine on oluline osa taastusravist. FIM on maailmas laialdaselt kasutusel olev patsiendi funktsionaalset võimekust hindav mõõdik.
 Eesmärk oli FIMi praktilise kasutamise hindamine Keila Taastusravikeskuses insuldipatsientide taastusravis, kus mõõdikut kasutas multidistsiplinaarne meeskond.
 Tulemused. Uuringusse kaasati 112 patsienti, kes olid saadetud taastusravile Keila Taastusravikeskusesse ajavahemikul 04.10.2011–10.04.2012. Hinnati nii esmase kui ka korduva isheemilise ja hemorraaglise insuldiga patsiente. Patsientide keskmine vanus oli 71,3 aastat, keskmine ravilviibimise pikkus 18 päeva. Keskmine FIM-skoor ravile saabumisel oli 71,8 punkti ja ravilt lahkumisel 83,1 punkti. Paranemine raviaja jooksul oli 11,3 punkti ehk 15,8%. Suurim funktsionaalne paranemine esines patsientidel, kelle FIM-skoor ravile saabumisel oli 37–90 punkti.
 Järeldus. Meie uuringu patsientide keskmised FIM-skoorid ravile saabumisel on võrreldavad teiste riikide analoogsete uuringute tulemustega. Väiksem FIM-skoori muutus taastusraviperioodi jooksul meie uuringu patsientidel on tingitud lühemast ravilviibimise pikkusest ja patsientide kõrgemast vanusest võrreldes teiste riikide uuringutega, samuti asjaolust, et uuringus ei olnud eristatud esmaseid insulte korduvatest. Suurim positiivne funktsionaalse seisundi muutus saavutatakse keskmise raskusega funktsioonihäire korral ravile saabudes (FIM-skoor 37–90 punkti). FIM-skoori hinnates ilmneb, et taastusraviperioodi pikkuse üle tuleb otsustada individuaalselt, lähtudes haige funktsioonihäire raskusest.

description: In the past, several projects have been conducted at Bear Lake, Utah-Idaho, by the Utah State University through the Wildlife Resources Department, in conjunction with the Utah and Idaho fish and game departments, the Fish and Wildlife Service , and the National Science Foundation. These projects have dealt primarily with limnology, limnological techniques, fish life histories, fish movements, and bottom fauna in the pelagic and benthic areas of the lake. Subsequently, a littoral zone project was set up to study some of the ecological aspects of the shallow waters of Bear Lake, and some of the influences that this area may have on the entire lake.

description: Real-time monitoring of human behaviours, especially in e-Health applications, has been an active area of research in the past decades. On top of IoT-based sensing environments, anomaly detection algorithms have been proposed for the early detection of abnormalities. Gradual change procedures, commonly referred to as drift anomalies, have received much less attention in the literature because they represent a much more challenging scenario than sudden temporary changes (point anomalies). In this paper, we propose, for the first time, a fully unsupervised real-time drift detection algorithm named DynAmo, which can identify drift periods as they are happening. DynAmo comprises a dynamic clustering component to capture the overall trends of monitored behaviours and a trajectory generation component, which extracts features from the densest cluster centroids. Finally, we apply an ensemble of divergence tests on sliding reference and detection windows to detect drift periods in the behavioural sequence.

The first two thirds, from the first decade of the fourteenth century, contain a fragment of the world chronicle ascribed to Baudouin d'Avesnes, and its illuminations can be attributed to a painter from the circle of Renaud de Bar in Metz. The last third, produced up to the middle of the fourteenth century, is composed of different devotional texts of a still poorly-studied corpus. Many of these texts can be found in other manuscripts that today can be found in Bern, Paris, and Metz, and can be ascribed to the later convent of the Celestines in Metz. This volume, which in 1570 was still in private hands, came to Bern in 1632 through Jacques Bongars.

description: We study the type III migration of a Saturn mass planet in low viscosity discs. The planet is found to experience cyclic episodes of rapid decay in orbital radius, each amounting to a few Hill radii. We find this to be due to the scattering of large- scale vortices present in the disc. The origin and role of vortices in the context of type III migration is explored. It is shown through numerical simulations and semi- analytical modelling that spiral shocks induced by a sufficiently massive planet will extend close to the planet orbital radius. The production of vortensity across shock tips results in thin high vortensity rings with a characteristic width of the local scale height. For planets with masses equal to and above that of Saturn, the rings are co-orbital features extending the entire azimuth. Linear stability analysis show there exists unstable modes that are localised about local vortensity minima which coincide with gap edges. Simulations show that vortices are non-linear a outcome. We used hydrodynamic simulations to examine vortex-planet interactions. Their effect is present in discs with kinematic viscosity less than about an order of magnitude smaller than the typically adopted value of ν= 10^{-5}Ω_pr_p(0)^2, where r_p(0) and Ω_p are the initial orbital radius and angular velocity of the planet respectively. We find that the magnitude of viscosity affects the nature of type III migration but not the extent of the orbital decay. The role of vortices as a function of initial disc mass is also explored and it is found that the amount of orbital decay during one episode of vortex-planet interaction is independent of initial disc mass. We incorporate the concept of the co-orbital mass deficit in the analysis of our results and link it to the presence of vortices at gap edges.

description: We present new CO ($J=5-4$ and $7-6$) and [CI] ($^3P_2\,-\, ^3P_1$ and $^3P_1\,-\, ^3P_0$) emission line observations of the star-forming galaxy D49 at the massive end of the Main Sequence at $z=3$. We incorporate previous CO ($J=3-2$) and optical-to-millimetre continuum observations to fit its spectral energy distribution (SED). Our results hint at high-$J$ CO luminosities exceeding the expected location on the empirical correlations with the infrared luminosity. [CI] emission fully consistent with the literature trends is found. We do not retrieve any signatures of a bright active galactic nucleus that could boost the $J=5-4,\,7-6$ lines in either the infrared or X-ray bands, but warm photon-dominated regions, shocks or turbulence could in principle do so. We suggest that mechanical heating could be a favourable mechanism able to enhance the gas emission at fixed infrared luminosity in D49 and other main-sequence star-forming galaxies at high redshift, but further investigation is necessary to confirm this explanation. We derive molecular gas masses from dust, CO, and [CI] that all agree within the uncertainties. Given its large star formation rate (SFR) $\sim 500~M_\odot~{\rm yr}^{-1}$ and stellar mass $>10^{11.5}~M_\odot$, the short depletion time scale of $<0.3$ Gyr might indicate that D49 is experiencing its last growth spurt and will soon transit to quiescence.

An analog-to-digital conversion circuit using a stack of tunnel diodes each constructed from the same material

Publisher: name: University of British Columbia
Year: 2011

description: This thesis describes a mathematical-graphical analysis and some analog computer simulation studies that were carried out to determine the feasibility of a proposed circuit to be used for analog-to-digital conversion. The circuit analysed and simulated contains a stack of tunnel diodes which are constructed from the same type of semiconductor material. The switching characteristics of this circuit are controlled primarily by the ratios and the values of the capacitances which shunt the individual tunnel diodes and to a lesser extent by the interdiode capacitances. This is revealed in a study of the effects of different circuit parameter variation A two tunnel diode stack circuit (two bits of information capacity) is analysed by studying the nature of the switching trajectories in the proximity of the singular points of the equations describing -the circuit operation. Three different modes of operation, each of which differs in the manner in which the 11 state is reached, are revealed for this circuit. The analysis indicates a feature of the circuit which can be used to determine the final state of the circuit before steady state conditions have been reached. An extension of the two tunnel diode stack circuit to one containing three tunnel diodes yielded eight stable and accessible states. This indicates that the circuit proposed will be able to realize 2[superscript n] states with n tunnel diodes. It is shown that different interdiode capacitance connections will facilitate the achievement of this result.

description: We report a detailed analysis of the XMM-Newton spectra of six Narrow-Line Seyfert 1 (NLS1) galaxies at redshift z = 0.35--0.92. Compared with the NLS1s at lower redshift in the previously most-studied sample, these NLS1s have larger black hole (BH) masses ($\log\,M_\text{BH}>7.5$) with similar or even lower Eddington ratios. Our extended XMM-Newton sample of NLS1s shows strong soft X-ray excess emission below 2 keV. The quantified soft excess strength does not show an obvious discrepancy from previous studies of the lower-redshift NLS1s. The systematic effect in the measurement of the Eddington ratio mainly lies in the bolometric correction factor. We also tentatively fit the spectra assuming two more physical models for the soft excess: warm Comptonization and relativistic reflection from the inner accretion disk. In the first scenario, we confirm the ubiquity of a warm and optically thick corona. The behavior of a single source can be better explained by relativistic reflection, although we cannot distinguish which model is a more favorable explanation for the soft excess based on the best-fit statistics.

description: This Greek manuscript, dating primarily from the tenth century, contains the letters of Paul along with chains of commentaries. It shares similarities with the manuscripts of the so-called “scriptorium of Ephrem” of Constantinople. In that same city, in the fifteenth century, John of Ragusa, legate of the Council of Basel, bought the codex, which he then bequeathed after his death to the Dominicans of Basel. Erasmus used it for his text of the Pauline Epistles as part of his first edition of the Greek New Testament (1516). Erasmus’ printer, Johannes Froben, left annotations on the pages.

description: Occurrences of tropical cyclones at a location are rare, and for many locations, only short periods of observations or hindcasts are available. Hence, estimation of return values (corresponding to a period considerably longer than that for which data is available) for cyclone-induced significant wave height (SWH) from small samples is challenging. The STM-E (space-time maximum and exposure) model was developed to provide reduced bias in estimates of return values compared to competitor approaches in such situations, and realistic estimates of return value uncertainty. STM-E exploits data from a spatial neighbourhood satisfying certain conditions, rather than data from a single location, for return value estimation. This article provides critical assessment of the STM-E model for tropical cyclones in the Caribbean Sea near Guadeloupe for which a large database of synthetic cyclones is available, corresponding to more than 3,000 years of observation. Results indicate that STM-E yields values for the 500-year return value of SWH and its variability, estimated from 200 years of cyclone data, consistent with direct empirical estimates obtained by sampling 500 years of data from the full synthetic cyclone database; similar results were found for estimation of the 100-year return value from samples corresponding to approximately 50 years of data. In general, STM-E also provides reduced bias and more realistic uncertainty estimates for return values relative to single location analysis.

description: Kompleksne regionaalne valusündroom (CRPS, complex regional pain syndrome) on krooniline haigusseisund. Sel puhul on vaevusteks kahjustatud piirkonna – enamasti jäseme – valu, turse, liikuvuse piiratus, nahatemperatuuri muutus ja teised vasomotoorse ebastabiilsuse nähud ning luude demineralisatsioon. Vaevused kujunevad enamasti trauma järel. Tegemist on välistamisdiagnoosiga. Lisaks kliinilisele pildile on abistavaks radioloogilised uuringud (stsintigraafia, MRT). Haiguse etioloogia ei ole selge, samuti pole kindlalt tõhusaid ravimeetodeid.

description: This paper constructs in the framework of algebraic quantum field theory (AQFT) the linear Chern-Simons/Wess-Zumino-Witten system on a class of $3$-manifolds $M$ whose boundary $\partial M$ is endowed with a Lorentzian metric. It is proven that this AQFT is equivalent to a dimensionally reduced AQFT on a $2$-dimensional manifold $B$, whose restriction to the $1$-dimensional boundary $\partial B$ is weakly equivalent to a chiral free boson.

title: Factors Influencing Student-Athletes to Enroll in Utah Colleges
Creators: name: Hall, Garth V.
Publisher: name: Utah State University
Year: 1972

description: The specific factors that influence student-athletes to enroll in Utah colleges were studied at Utah State University, Weber State College, University of Utah, Westminster College, Brigham Young University, and College of Southern Utah.
The intercollegiate sports surveyed were football, basketball, track and field, wrestling, and baseball.
Factors influencing student-athletes to attend certain institutions varied from one athlete to another. Academic programs, level of competition, amount of financial aid, reputation of the athletic programs and institutions, as well as general facts of the programs were evaluated prior to selecting certain financial aid awards.
Recruiting coaches were found to be very influential on the student-athletes and were responsible for dispensing the most helpful information to them.
Most student-athletes were receiving some financial aid and were actively recruited by representatives of athletic departments.

description: In this work, we describe strategies and provide case-study activities that can be used to examine the properties of superposition, entanglement, tagging, complementarity, and measurement in quantum curricula geared for teacher training. Having a solid foundation in these conceptual ideas is critical for educators who will be adopting quantum ideas within the classroom. Yet they are some of the most difficult concepts to master. We show how one can systematically develop these conceptual foundations with thought experiments on light and with thought experiments that employ the Stern-Gerlach experiment. We emphasize the importance of computer animations in aiding the instruction on these concepts.

Year: 2024

description: This richly illuminated manuscript is a Greek Tetravangelion of Italo-Byzantine origin copied in the eighth or ninth century in a biblical uncial script. Some scholars have connected the uncommon style of its decoration with, on the one hand, Byzantine art of the Iconoclastic Period, and on the other hand, with the aesthetic of churches and artefacts from the period of the Byzantine Exarchate of Ravenna. In the fifteenth century, John of Ragusa, legate of the Council of Basel, bought the codex in Constantinople, and then bequeathed it on his death to the Dominicans of Basel.

A Flexible Multi-Metric Bayesian Framework for Decision-Making in Phase II Multi-Arm Multi-Stage Studies

description: We propose a multi-metric flexible Bayesian framework to support efficient interim decision-making in multi-arm multi-stage phase II clinical trials. Multi-arm multi-stage phase II studies increase the efficiency of drug development, but early decisions regarding the futility or desirability of a given arm carry considerable risk since sample sizes are often low and follow-up periods may be short. Further, since intermediate outcomes based on biomarkers of treatment response are rarely perfect surrogates for the primary outcome and different trial stakeholders may have different levels of risk tolerance, a single hypothesis test is insufficient for comprehensively summarizing the state of the collected evidence. We present a Bayesian framework comprised of multiple metrics based on point estimates, uncertainty, and evidence towards desired thresholds (a Target Product Profile) for 1) ranking of arms and 2) comparison of each arm against an internal control. Using a large public-private partnership targeting novel TB arms as a motivating example, we find via simulation study that our multi-metric framework provides sufficient confidence for decision-making with sample sizes as low as 30 patients per arm, even when intermediate outcomes have only moderate correlation with the primary outcome. Our reframing of trial design and the decision-making procedure has been well-received by research partners and is a practical approach to more efficient assessment of novel therapeutics.

description: We report experimental measurements of high-order harmonic spectra generated in Ar using a carrier-envelope-offset (CEO) stabilized 12 fs, 800nm laser field and a fraction (less than 10%) of its second harmonic. Additional spectral peaks are observed between the harmonic peaks, which are due to interferences between multiple pulses in the train. The position of these peaks varies with the CEO and their number is directly related to the number of pulses in the train. An analytical model, as well as numerical simulations, support our interpretation.
Südame areng ja kaasasündinud rikked. Biomehaaniline perspektiiv

description: Südamerikked ilmnevad umbes 1%-l elusalt sündinud lastest. Uuringud on näidanud, et kõigist kaasasündinud riketest esinevad kõige sagedamini südamerikked. Viimase aja uuringud on esile toonud mitmeid põhjusi, mis soodustavad kaasasündinud südamerikete kujunemist. Ühelt poolt võib sellel olla molekulaarbioloogiline põhjus – geenimutatsioon –, mis on tingitud nukleotiidide muutustest geenides (1). Teiselt poolt on mõjuteguriks emakasisene keskkond, mida võib mõjutada ema eluviis ja käitumine, näiteks alkoholitarbimine, suitsetamine, narkootikumide, ravimite tarvitamine (2, 3). Samuti võib embrüo areng olla häiritud mõningate toitainete puudusest emal, näiteks foolhappe puudus ja sellest tulenev homotsüsteiinisisalduse suurenemine veres (4). Kirjeldatud tegurid võivad mõjutada loote arengut väga varajases perioodis, kui ema veel ei teagi, et ta on rase. Harilikult tuvastab naine raseduse 5.–6. nädalal pärast viljastumist. Tuksuv süda ja vereringe kujuneb lootel juba 3. viljastumisjärgsel nädalal (16.–21. päeval). Seega võivad südame arengut mõjutavad tegurid toimida juba siis, kui naine ei olegi oma rasedusest teadlik. Südamerikete kujunemise põhjuste selgitamiseks on vaja uurida loote arengu väga varajasi perioode.

description: We extract from the Sloan Digital Sky Survey a sample of 347 systems involving early type galaxies separated by less than 30 kpc, in projection, and 500 km/s in radial velocity. These close pairs are likely progenitors of dry mergers. The (optical) spectra is used to determine how the interaction affects the star formation history and nuclear activity of the galaxies. The emission lines (or lack thereof) are used to classify the sample into AGN, star forming or quiescent. Increased AGN activity and reduced star formation in early-type pairs that already appear to be interacting indicate that the merging process changes the nature of nebular activity, a finding that is also supported by an increase in AGN luminosity with decreasing pair separation. Recent star formation is studied on the absorption line spectra, both through principal component analysis as well as via a comparison of the spectra with composite stellar population models. We find that the level of recent star formation in close pairs is raised relative to a control sample of early-type galaxies. This excess of residual star formation is found throughout the sample of close pairs and does not correlate with pair separation or with visual signs of interaction. Our findings are consistent with a scenario whereby the first stage of the encounter (involving the outer parts of the halos) trigger residual star formation, followed by a more efficient inflow towards the centre -- switching to an AGN phase -- after which the systems are quiescent.
