description: We propose a unified description of intersubband absorption saturation for quantum wells inserted in a resonator, both in the weak and strong light-matter coupling regimes. We demonstrate how absorption saturation can be engineered. In particular we show that the saturation intensity increases linearly with the doping in the strong coupling regime, while it remains doping independent in weak coupling. Hence, countering intuition, the most suitable region to exploit low saturation intensities is not the ultra-strong coupling regime, but is instead at the onset of the strong light-matter coupling. We further derive explicit conditions for the emergence of bistability. This work sets the path towards yet unexisting ultrafast mid-infrared semiconductor saturable absorption mirrors (SESAMs) and bistable systems. As an example, we show how to design a mid-infrared SESAM with a three orders of magnitude reduction in saturation intensity, down to about 5 kW/cm2.

description: Mit Antisemitismus in Polen 1968. Interaktion zwischen Partei und Gesellschaft hat Hans-Christian Dahlmann die erste deutschsprachige Monografie zur „antizionistischen“ Kampagne von 1968 vorgelegt. Im Unterschied zu vorherigen polnischsprachigen Forschungsarbeiten analysiert der Autor dabei nicht nur die Rolle der Parteiführung, sondern auch das Mitwirken der mittleren und unteren Parteiebenen. Er kommt zu dem durchaus überraschenden Ergebnis, dass diese entscheidend und relativ autonom die antisemitische Kampagne vorangetrieben haben. Als Folge der Ereignisse von 1968 musste mehr als die Hälfte der noch 30.000 in Polen lebenden Juden das Land verlassen. Machtkampf in Polen In der gängigen Forschungsliteratur wird die antisemitische Kampagne auf das Zusammenspiel zweier unterschiedlich gelagerter Konflikte zurückgeführt. Einerseits diente der Antisemitismus dazu, die aufkeimende Oppositionsbewegung zu schwächen. Ein Teil der studentischen Oppositionellen, die sich im Frühjahr 1968 gegen die restriktive Kulturpolitik und die staatlichen Repressionen zur Wehr setzten, war jüdischer Herkunft. Die Führung der Polnischen Vereinigten Arbeiterpartei nahm dies zum Anlass, die Oppositionsbewegung als von „Zionisten“ unterwandert und im Dienste „fremder“ Interessen agierend zu diskreditieren. Andererseits war die antisemitische Kampagne Produkt eines innerparteilichen Machtkampfes. Der 1964 zum Innenminister ernannte Mieczysław Moczar lancierte die Kampagne mit dem Ziel, rivalisierende Parteifunktionäre aus ihren Positionen zu drängen und mit eigenen Gefolgsleuten neu zu besetzen. Ihm gelang es dadurch, seine Machtbasis innerhalb der Partei erheblich auszubauen.

description: A field theoretical renormalization group approach at two loop level is applied to the homogeneous spin-1 Bose gas in order to investigate the order of the phase transition. The beta function of the system with $d=4-ε$ dimensions is determined up to the third power of the coupling constants and the system's free energy on the border of the classical stability is given in next to leading order. It is found that the phase transition of the interacting spin-1 Bose gases with weak spin-dependent coupling constant values is of first order.

description: We formulate Positivity Bounds for scattering amplitudes including exchange of massless particles. We generalize the standard construction through dispersion relations to include the presence of a branch cut along the real axis in the complex plane for the Maldestam variable $s$. In general, validity of these bounds require the cancellation of divergences in the forward limit of the amplitude, proportional to $t^{-1}$ and $\log(t)$. We show that this is possible in the case of gravitons if one assumes a Regge behavior of the amplitude at high energies below the Planck scale, as previously suggested in the literature, and that the concrete UV behaviour of the amplitude is uniquely determined by the structure of IR divergences. We thus extend previous results by including a sub-leading logarithmic term, which we show to be universal. The bounds that we present here have the potential of constraining very general models of modified gravity and EFTs of matter coupled to gravitation.

description: The very first recruitment for a public relations practitioner in Malaysia was encountered in 1948 and was advertised by the federal government of the British Colony in Malaya. This paper examines the subsequent advertisements after Malaya sought independence from the British colonial government. A total of eleven recruitment advertisements were found before the formation of Malaysia on the 16th
September 1963. This paper outlines the advertisers, the titles of positions, as well as their qualifications and duties. The results show that the job requirement mainly came from the federal and local governments. Generally, the duties were related to information services and some specific responsibilities.

description: Traffic accidents are a leading cause of injury and death worldwide, making immediate first aid interventions critical for improving survival rates and reducing the severity of injuries. This systematic review examines current best practices in first aid responses during traffic accidents, focusing on key life-saving interventions, challenges faced by bystanders and first responders, and the tools and techniques most effective in stabilizing victims before professional medical help arrives. A comprehensive literature search was conducted to evaluate studies, clinical guidelines, and case reports related to traffic accident first aid. Findings indicate that early intervention through scene assessment, airway management, hemorrhage control, and communication with emergency services significantly improves outcomes. However, the lack of public first aid training, panic at accident scenes, and legal uncertainties for bystanders remain persistent challenges. Recommendations for improving first aid responses include expanding public first aid education, increasing access to essential first aid kits in vehicles, and leveraging technology for real-time guidance. The review highlights the need for ongoing research into innovative first aid tools and the impact of widespread public training on traffic accident outcomes.

Keywords: First aid, traffic accidents, emergency response, bystander intervention, hemorrhage control, airway management, public training, survival outcomes, first aid tools, emergency medical services.
Before non-finito: a rough aesthetic in quattrocento sculpture from Donatello to Michelangelo
Creators: name: Mack, Stephen
Publisher: name: No Publisher Supplied
Year: 2021

description: Fifteenth-century sculpture is usually associated with the rigorous smooth polish of Verrocchio’s Doubting Thomas, Lorenzo Ghiberti’s Baptistery Doors, or the pulitezza of the della Robbia workshop’s glazed terracotte. However, this dissertation seeks to demonstrate that quattrocento views about sculptural finish were not homogenous by studying a group of artworks, mainly bronzes, in which extensive hammering is visible on the final product, elements are cast from minimally modeled waxes, or there are wholly unpolished passages. The presence of several dozen quattrocento works with these characteristics, many of which were displayed publicly, suggests that the alternative style had an audience. The rough aesthetic was often utilized in sculptures that would be manipulated by hand or examined in close detail, where each abraded surface could be observed, necessarily making the artist’s process visible to observers. By calling attention to their creative process, fifteenth-century artists also underscored their transformative capabilities and mastery over their craft. Examining these sculptures as a cohesive group, I argue that it is possible to see a burgeoning interest in sculptor’s process as a subject of art, a phenomenon usually ascribed to the following century and ultimately to modernism.Donatello appears to be the progenitor of the rough aesthetic, and therefore he is the subject of chapters one and two. The first demonstrates how he used minimal modeling and ostentatious cold working for dramatic effect in his decoration for the Old Sacristy, San Lorenzo, Florence; the Lamentation now in the Victoria and Albert Museum, London; and the series of reliefs now installed as pulpits in San Lorenzo, Florence. The second focuses on how Donatello’s art – and the musicians balcony made for the Florentine Duomo in particular – would come to be at the center of debates about artistic finish in the sixteenth century. The third chapter is about a group of masterful rough aesthetic bronze reliefs by a single artist – considering a Flagellation relief now in the Galleria Nazionale dell'Umbria, Perugia, in special detail – which questions the current attribution of the reliefs to the multifaceted Sienese artist, Francesco di Giorgio Martini. The final chapter considers how the rough aesthetic was utilized in all'antica sculpture made in Florence during the Laurentian period. A coda discusses the rough aesthetic’s possible impact on Michelangelo.

description: Innerhalb der zweiundvierzig Jahre ihrer Existenz (1948-1990) hatte die in der Volksrepublik Polen de facto alleinregierende Polnische Vereinigte Arbeiterpartei (PZPR) insgesamt fast vier Millionen Mitglieder. Die Partei mit ihrer Nomenklatur war bemüht alle wichtigen gesellschaftlichen, politischen und wirtschaftlichen Bereiche des Lebens im Staatssozialismus zu kontrollieren und zu steuern. Umso erstaunlicher ist es, dass es bis heute keine wissenschaftliche Monographie über die PZPR gibt. Der vorliegende Sammelband füllt diese Lücke insofern, als er den aktuellsten Forschungsstand über die PZPR präsentiert.[1] Sechszehn renommierte polnische ZeithistorikerInnen fassen ihre langjährigen Forschungen zusammen und stellen in fünfzehn Artikeln die Partei als eine „Herrschaftsmaschine" vor. Vier beschäftigen sich mit der Parteigeschichte aus biographischer Perspektive. Jerzy Eisler fasst bisherige Forschungen zu den Ersten Sekretären der Partei zusammen und bemerkt, dass ihre Lebensgeschichten sowie die Wechselwirkungen zwischen persönlichen Charakterzügen und der Art der Partei- und Staatsführung immer noch unzureichend beleuchtet bleiben. Andrzej Friszke und Leszek Gilejko befassen sich jeweils mit den in den Parteikomitees angestellten MitarbeiterInnen sowie mit „gewöhnlichen" Parteimitgliedern. Sie widmen sich dabei vor allem statistischen Daten über soziale und politische Herkunft, Bildung, Alter und Geschlecht, während eine weitergehende Interpretation der Daten nur kurz skizziert wird. Bożena Szaynok konzentriert sich auf die Problematik der jüdischen Mitglieder der PZPR und erinnert an eine vergessene Tatsache, dass die Kommunisten seit 1944 verschiedene jüdische Organisationen und Parteien zugelassen haben, während dies den anderen religiösen und ethnischen Minderheiten nicht erlaubt worden sei (S. 316). Spätestens seit dem Abbruch der diplomatischen Beziehungen zu Israel 1967 wurde der Antisemitismus in der Partei nicht nur offensichtlich, sondern auch zugelassen und beispielsweise in Form von der Patriotischen Vereinigung „Grunwald" offiziell sanktioniert.

description: Methods are proposed for measuring the ratio $R^{+/0} = Γ(Υ(4S) \to B^+ B^-)/$ $Γ(Υ(4S) \to \bo \ob)$ without assuming isospin invariance in exclusive hadronic decays such as $B \to J/ψK$. The validity of isospin invariance in various B decays is discussed. Isospin violations are expected to be especially small in inclusive semileptonic decays, so that $Γ(B^+ \to X_c^0 \ell^+ ν_\ell) = Γ(B^0 \to X_c^- \ell^+ ν_\ell)$ is expected to hold at the sub-percent level. Suggestions are made for utilizing this relation. The accuracy of a ``double-tag'' method for obtaining $R^{+/0}$, such as that used for measuring the $D^+ D^-/D^0 \od$ ratio at the $ψ'' \equiv ψ(3770)$, is also estimated.

description: For this work the Geo-referenced Regional Exposure Assessment Tool for European Rivers (GREAT-ER) was developed further to support river basin management and the implementation process within the EU Water Framework Directive (WFD). This was achieved through predicting spatially resolved pharmaceutical exposure concentrations in whole watersheds. A major focus of this thesis has been placed on modeling challenging watersheds, whereby challenging can refer to hydrological conditions in a watershed as well as to specific emission patterns that occur within the watersheds. The adapted methodology improves the prediction accuracy in such watersheds with GREAT-ER with respect to pharmaceutical exposures, but can also lead to improved results in other application areas. The possibilities of the latest model version are demonstrated by the extensive inclusion of local and regional conditions. In watersheds with highly variable and seasonally changing hydrological situations, GREAT-ER has been applied satisfactorily for the first time, and additionally, the developed approach can be transferred to equivalent watersheds worldwide. Comparison with monitoring data confirms that some of the adjustments have resulted in significantly improved model predictions, especially when hydrological and local conditions are specifically addressed. For example, explicit consideration of local drug emissions from hospitals or private medical practices (e.g., for x-ray contrast agents) can improve predictions at the local scale without compromising regional exposure estimates. Pharmaceuticals that have low concentrations and are barely detectable with established analytical methods can be evaluated with model simulations. In addition, current management strategies implemented under the WFD has been replicated and evaluated. These management scenarios simulated with the model allow an a priori evaluation of risk reduction measures. In combination with targeted monitoring approaches, it was shown that the GREAT-ER model can serve as a valuable tool for exposure and risk assessment of pharmaceuticals even in challenging watersheds. This and the useful combination of targeted monitoring and GREAT-ER simulations and the ability of the modeling approach to predict the expected range of spatial surface water concentrations is demonstrated by three selected journal articles.

description: A mathematical model for collision-induced breakage is considered. Existence of weak solutions to the continuous nonlinear collision-induced breakage equation is shown for a large class of unbounded collision kernels and daughter distribution functions, assuming the collision kernel $K$ to be given by $K(x,y)= x^α y^β + x^β y^α$ with $α\le β\le 1$. When $α+ β\in [1,2]$, it is shown that there exists at least one weak mass-conserving solution for all times. In contrast, when $α+ β\in [0,1)$ and $α\ge 0$, global mass-conserving weak solutions do not exist, though such solutions are constructed on a finite time interval depending on the initial condition. The question of uniqueness is also considered. Finally, for $α<0$ and a specific daughter distribution function, the non-existence of mass-conserving solutions is also established.
title: Portable and versatile cold atom experiments

Publisher: name: University of St Andrews
Year: 2019

description: This thesis describes the progress achieved towards two goals. One is the construction of a compact magneto-optical trap (MOT) apparatus, used both as a standalone undergraduate laboratory experiment and as part of a public engagement demonstration of cold atom physics. The setup, which utilises a dichroic atomic vapour laser lock (DAVLL) system plus homemade sideband generation electronics, is capable of trapping and cooling up to 8x10⁷ ⁸⁵Rb atoms in a standard six-beam laser cooling scheme. The second goal is the loading of an ultracold ensemble of ⁸⁷Rb atoms into novel optical trap geometries using a phase-only liquid crystal spatial light modulator (LC SLM) for applications to atomtronics and quantum simulation. Details of a double vacuum chamber apparatus, designed to produce the first Bose-Einstein condensates (BECs) at St Andrews, are provided. The setup incorporates a hybrid trap evaporative cooling scheme towards quantum degeneracy and reliably produces BECs of 1.9 10⁵ ⁸⁷Rb atoms. Two computational techniques, developed during the course of this project, are presented with the aim of creating flexible, smooth holographic optical traps. The first method illuminates a single SLM with overlapped, co-propagating light beams of different wavelengths to create a composite optical pattern for atom manipulation. The second uses conjugate gradient minimisation to create exceptionally high fidelity light patterns in both amplitude and phase for light in the output plane. These techniques, combined with the implementation of a light sheet into the experimental setup, are used to trap atoms in both a ring profile and in a set of narrow waveguides connected with a tunnelling barrier.

Examined species: Angulyagra cf. polyzonata (Frauenfeld, 1862)
(Figs 4T, 5T, 7T).
Remarks: Apart from Notopala, Angulyagra can be distinguished from other genera with a concentric inverted-comma-shaped operculum by the following combination of characters: a relatively small nuclear region with shiny grains or veins, a relatively thick enamel layer and a thin marginal region that obviously differs in colour from the enamel region.
One species of Angulyagra (total of three specimens with operculum) has been examined for this study (Table 1).

description: Recently Kovner and Lublinsky proposed a set of equations which can be viewed as dual to JIMWLK evolution. We show that these dual equations have a natural dipole-like structure, as conjectured by Kovner and Lublinsky. In the high energy large N_c limit these evolution equations reduce to equations previously derived in the dipole model. We also show that the dual evolution kernel is scheme dependent, although its action on the weight functional describing a high energy state gives a unique result.

description: Based on data from 92 Minnesota cities, the analyses shows that neither marginal price or average price appear as the better predictor of demand. The price elasticity of demand ranges from -. 17 for marginal price in the linear model to -.27 for average price in the log linear model. It appears from the analysis that many consumers are unaware of the marginal price of their water. Thus utilities should simplify their pricing structures and present consumers with an easy to understand costs of water such as the cost of six hours of lawn watering.

description: We study the $\NN=2$ string theory or the $\NN=4$ topological string on the deformed CHS background. That is, we consider the $\NN=2$ minimal model coupled to the $\NN=2$ Liouville theory. This model describes holographically the topological sector of Little String Theory. We use degenerate vectors of the respective $\NN=2$ Verma modules to find the set of BRST cohomologies at ghost number zero--the ground ring, and exhibit its structure. Physical operators at ghost number one constitute a module of the ground ring, so the latter can be used to constrain the S-matrix of the theory. We also comment on the inequivalence of BRST cohomologies of the $\NN=2$ string theory in different pictures.

Mountains of money : the corporate production of Whistler resort
Creators: name: Horner, Graham
Publisher: name: University of British Columbia
Year: 2009

description: The aim of this thesis is two-fold. My primary, theoretical aim is to present an alternative way for geographers to approach the study of tourist resort development. For over twenty years, resorts have been understood through the framework of evolutionary models, the most widely-used being Richard Butler's 1981 Tourist Area Life Cycle. I argue that the time is ripe for a more sophisticated approach which i) identifies the multiplicity of actors involved in the destination-making process and elucidates the interactions between them; and ii) situates the resort within a dynamic, capitalist economy, increasingly dominated by large corporations. I suggest that one way we can do this is to take particular moments in a resort's trajectory and examine the responses made by key players in the production of the resort. My starting point for my investigation into Whistler Resort, British Columbia is the merger in 1996 of its two ski mountains, Whistler and Blackcomb, under the ownership of Intrawest Corporation. A recent wave of consolidation in the North American ski industry has seen increasing numbers of once-independent ski areas coming under the control of four large corporations, Intrawest being one. My second aim with this thesis, therefore, is to shed light on the process of ski resort development in light of the recent industry reorganisation. In particular, I use my case-study of Whistler to interrogate the corporatisation thesis of historian Hal Rothrnan. Rothman's account of resort development in the twentieth-century American West leads him to view large corporations as extractive forces which pay scant respect to local communities and cultures, treating them instead as marketable commodities. The experience of Whistler, however, suggests a much greater degree of mterdependence and co-operation between the ski corporation and local stakeholders in the resort - a situation that arises because of its unique administrative, political and economic context.

description: We establish global-in-time existence results for thermodynamically consistent reaction-(cross-)diffusion systems coupled to an equation describing heat transfer. Our main interest is to model species-dependent diffusivities, while at the same time ensuring thermodynamic consistency. A key difficulty of the non-isothermal case lies in the intrinsic presence of cross-diffusion type phenomena like the Soret and the Dufour effect: due to the temperature/energy dependence of the thermodynamic equilibria, a nonvanishing temperature gradient may drive a concentration flux even in a situation with constant concentrations; likewise, a nonvanishing concentration gradient may drive a heat flux even in a case of spatially constant temperature. We use time discretisation and regularisation techniques and derive a priori estimates based on a suitable entropy and the associated entropy production. Renormalised solutions are used in cases where non-integrable diffusion fluxes or reaction terms appear.

description: A simple 3D-reconstruction method for gamma-ray induced air showers is presented, which takes full advantage of the assets of a system of Atmospheric Cherenkov Telescopes combining stereoscopy and fine-grain imaging like the High Energy Stereoscopic System (H.E.S.S.). The rich information collected by the cameras allows to select electromagnetic showers on the basis of their rotational symmetry with respect to the incident direction, as well as of their relatively small lateral spread. In the framework of a 3D-model of the shower, its main parameters -- incident direction, shower core position on the ground, slant depth of shower maximum, average lateral spread of Cherenkov photon origins (or ``photosphere 3D-width'') and primary energy -- are fitted to the pixel contents of the different images. For gamma-ray showers, the photosphere 3D-width is found to scale with the slant depth of shower maximum, an effect related to the variation of the Cherenkov threshold with the altitude; this property allows to define a dimensionless quantity omega (the ``reduced 3D-width''), which turns out to be an efficient and robust variable to discriminate gamma-rays from primary hadrons. In addition, the omega distribution varies only slowly with the gamma-ray energy and is practically independent of the zenith angle. The performance of the method as applied to H.E.S.S. is presented. Depending on the requirements imposed to reconstructed showers, the angular resolution at zenith varies from 0.04 to 0.1 degrees and the spectral resolution in the same conditions from 15% to 20%.

description: Algorithms and other formal models purportedly incorporating human values like fairness have grown increasingly popular in computer science. In response to sociotechnical challenges in the use of these models, designers and researchers have taken widely divergent positions on how formal models incorporating aspects of human values should be used: encouraging their use, moving away from them, or ignoring the normative consequences altogether. In this paper, we seek to resolve these divergent positions by identifying the main conceptual limits of formal modeling, and develop four reflexive values--value fidelity, appropriate accuracy, value legibility, and value contestation--vital for incorporating human values adequately into formal models. We then provide a brief methodology for reflexively designing formal models incorporating human values.

description: We present theoretical results concerning inelastic light (Raman) scattering from semiconductor quantum dots. The characteristics of each dot state (whether it is a collective or single-particle excitation, its multipolarity, and its spin) are determined independently of the Raman spectrum, in such a way that common beliefs used for level assignments in experimental spectra can be tested. We explore the usefulness of below band gap excitation and an external magnetic field to identify charge and spin excited states of a collective or single-particle nature.

We find clear evidence for the validity of the effective string model at the level of the NLO truncation.

description: Algae are a diverse class of photosynthetic organisms with many interesting phenotypes and can produce a wide range of natural bio-products. Microalgae can have fast growth rates and can be cultivated in bioreactors, providing high biomass yields from only the minimal inputs of trace elements, CO2, and sunlight. In recent years, techniques for genetic engineering of heterologous transgene expression in microalgae have been improved, opening a range of sustainable synthetic biotechnology applications that convert waste CO2 streams to high-value products. In the KAUST sustainable and synthetic biotechnology (SSB) lab we use the well-studied green alga Chlamydomonas reinhardtii as the host for biotechnological applications. C. reinhardtii contains a single chloroplast with a fully sequenced genome that can efficiently produce and correctly fold biologically active complex proteins including those with multiple disulfide bonds. Its transformation is relatively straightforward and molecular tools are available. In our work, we have developed, through chloroplast transformation, transgenic Chlamydomonas strains capable of using normally bio-unavailable phosphite as a phosphorus source. This strategy was chosen to help eliminate the use of antibiotics as a selective agent in culture media to prevent contamination by opportunistic microorganisms. This strategy overcomes one of the main challenges for commercially producing recombinant proteins in microalgae in an open or close culture systems at scale. Chloroplast transformation was performed using vortex and 0.1mm glass beads method in the presence of a synthetic plasmid, encoding a phosphite oxidoreductase (ptxD) which catalyses the conversion of phosphite into bio-available phosphate using NAD as a cofactor. The transformation was followed by selection on phosphite-containing medium and resulting strains were screened for efficient growth on phosphite as a sole source of phosphorous. A selected strain was subsequently transformed with plasmids to complement nitrate auxotroph (NIT1/NIT2) enabling growth in nitrate (NO3) containing media that are commonly used for high-density and industrial-scale cultivation concepts. Our results showed that the engineered strains could grow in phosphite-rich NO3 media and use phosphite as a phosphorous source while the wild-type parental strain could not. The generated strains will next be used to express a range of recombinant proteins using similar techniques to determine if the C. reinhardtii chloroplast can be used as an inexpensive and easily scalable platform system for sustainable recombinant protein production.

description: We study the optimization of the performance of arbitrary periodically driven thermal machines. Within the assumption of fast modulation of the driving parameters, we derive the optimal cycle that universally maximizes the extracted power of heat engines, the cooling power of refrigerators, and in general any linear combination of the heat currents. We denote this optimal solution as ``generalized Otto cycle'' since it shares the basic structure with the standard Otto cycle, but it is characterized by a greater number of fast strokes. We bound this number in terms of the dimension of the Hilbert space of the system used as working fluid. The generality of these results allows for a widespread range of applications, such as reducing the computational complexity for numerical approaches, or obtaining the explicit form of the optimal protocols when the system-baths interactions are characterized by a single thermalization scale. In this case, we compare the thermodynamic performance of a collection of optimally driven non-interacting and interacting qubits. Remarkably, for refrigerators the non-interacting qubits perform almost as well as the interacting ones, while in the heat engine case there is a many-body advantage both in the maximum power, and in the efficiency at maximum power. Additionally, we illustrate our general results studying the paradigmatic model of a qutrit-based heat engine. Our results strictly hold in the semiclassical case in which no coherence is generated by the driving, and finally we discuss the non-commuting case.

Precision turning of shafts with piezoelectric actuator tool

description: There is an increasing demand for high tolerances and good surface finish for most industrial applications of shafts such as the seats of roller bearings or gearwheel compression joints. A grinding or ultra-precision machine tool is used to finish these parts in the final production sequence because the conventional turning machine cannot meet the tolerances. This thesis investigates the use of a piezoelectric fast tool servo designed for precision turning of shafts on a conventional turning machine. In doing so, the grinding operation, the final process of precision machining, can be eliminated, which leads to significant savings in time and cost. A piezoelectric fast tool servo previously designed and developed for chatter vibration suppression is used for the investigation. It is mounted on a turret of a standard CNC turning center and is modeled as a second order dynamic system. Sliding mode control or variable structure control is used to control the actuator, taking advantage of its characteristics of robustness against disturbances and parameter uncertainties. The concept of using the piezoelectric actuator to accurately position the tool on a conventional machine and the effectiveness of the control scheme are verified both in simulations and experiments. Cutting experiments are carried out to identify the cutting conditions which produce the required surface quality. The effect of feedrate, cutting speed, tool geometry, and use of cutting fluids are investigated The results show that the surface quality that grinding offers can also be attained with the help of the piezoelectric actuator and proper selection of the cutting parameters.

Nonabelian Discrete Family Symmetry to Soften the SUSY Flavor Problem and to Suppress Proton Decay

description: Family symmetry could explain large mixing of the atmospheric neutrinos. The same symmetry could explain why the flavor changing current processes in supersymmetric standard models can be so suppressed. It also may be able to explain why the proton is so stable. We investigate these questions in a supersymmetric, renormalizable extension of the standard model, which possess a family symmetry based on a binary dihedral group Q_6. We find that the amplitude for μ\to e+γenjoys a suppression factor proportional to |(V_{MNS})_{e3}| ~ m_e/(\sqrt{2}m_μ) ~ 3.4\times 10^{-3}, and that B(p \to K^0 μ^+)/B(p \to K^0 e^+) ~ |(V_{MNS})_{e3}|^2 ~ 10^{-5}, where V_{MNS} is the neutrino mixing matrix.

description: Causal mediation analysis has historically been limited in two important ways: (i) a focus has traditionally been placed on binary treatments and static interventions, and (ii) direct and indirect effect decompositions have been pursued that are only identifiable in the absence of intermediate confounders affected by treatment. We present a theoretical study of an (in)direct effect decomposition of the population intervention effect, defined by stochastic interventions jointly applied to the treatment and mediators. In contrast to existing proposals, our causal effects can be evaluated regardless of whether a treatment is categorical or continuous and remain well-defined even in the presence of intermediate confounders affected by treatment. Our (in)direct effects are identifiable without a restrictive assumption on cross-world counterfactual independencies, allowing for substantive conclusions drawn from them to be validated in randomized controlled trials. Beyond the novel effects introduced, we provide a careful study of nonparametric efficiency theory relevant for the construction of flexible, multiply robust estimators of our (in)direct effects, while avoiding undue restrictions induced by assuming parametric models of nuisance parameter functionals. To complement our nonparametric estimation strategy, we introduce inferential techniques for constructing confidence intervals and hypothesis tests, and discuss open source software implementing the proposed methodology.
