title: Newspaper Representations of Homelessness: A Temporal Comparative Analysis
Creators: name: Werman, Sarah
Publisher: name: Utah State University
Year: 2019

description: This research focuses on the ways in which homelessness is discussed in two newspapers in a major city in the intermountain United States. I analyzed newspaper articles with the goal of understanding public discourse in two ideologically distinct newspaper venues. I examined the news media portrayal of the homeless in 752 articles in these two newspapers during two distinct six­-month time periods, one during which the city was nationally recognized as a major advocate for “Housing First,” or “solving homelessness,” and a more recent period during which urban gentrification has challenged the location of homeless services. Specifically, I addressed the he primary informants drawn upon by the newspapers, and the potential “missing voices” in the media discussion. My research looks at homelessness in these papers both over time and across papers.

description: In this paper, we propose a dense depth estimation pipeline for multiview 360° images. The proposed pipeline leverages a spherical camera model that compensates for radial distortion in 360° images. The key contribution of this paper is the extension of a spherical camera model to multiview by introducing a translation scaling scheme. Moreover, we propose an effective dense depth estimation method by setting virtual depth and minimizing photonic reprojection error. We validate the performance of the proposed pipeline using the images of natural scenes as well as the synthesized dataset for quantitive evaluation. The experimental results verify that the proposed pipeline improves estimation accuracy compared to the current state-of-art dense depth estimation methods.

description: In the industry, induction hardening of rotationally symmetrical workpieces by a single-shot process is a widespread method. Due to only partial superimposition of the workpiece areas to be heated by the coil, high power densities are often needed there. These lead to local hot spots, amounting to an intensive material stress and often result in a short lifetime of the inductor. In this paper, some numerically investigated models will be presented, revealing approaches, how to reduce mechanical stress in the single-shot coil and thus, enabling an increase of service life.
title: Quantifying the Predictability of Evolution at the Genomic Level in Lycaeides Butterflies
Creators: name: Chaturvedi, Samridhi
Publisher: name: Utah State University
Year: 2019

description: Stephen Jay Gould, a great scientist and evolutionary biologist, suggested that if we could replay the tape of life, we would not have observed similar course of events because evolution is stochastic and is affected by several events. Since then, the possibility that evolution is repeatable or predictable has been debated. Studies using large-scale evolution experiments, long-term data for individual populations, and controlled experiments in nature, have demonstrated phenotypic and genetic convergence in several taxa. These studies suggest that despite some randomness, predictable evolutionary patterns can emerge on a large temporal and spatial scale. However, a few cases also exist where evolution is unpredictable and stochastic. One way to understand evolutionary predictability better can be to have quantitative estimates of predictability at different heirarchical levels (mutations, genetic, phenotypic). This can help better understand if evolution is predictable and the extent to which it is predictable. My dissertation uses Lycaeides butterflies to identify and quantify evolutionary predictability in different contexts such as on a geographic scale, temporal scale and genomic scale. I accomplished this by sequencing and annotating the genomes of these butterflies across a vast geographic range and on a temporal scale and by comparing natural and experimental populations. My results show that different mechanisms can assist evolution of organisms to adapt to novel environmental challenges, and that the evolutionary changes can be somewhat predictable. Through this work I demonstrate three main findings: first, quantitative estimates of evolutionary predictability indicate that degree of predictability is variable and is highly context-dependent. Second, we can predict evolutionary patterns on a spatial as well as temporal scale, and can predict patterns in nature by controlled laboratory experiments. Additionally, genomic changes underlying repeatability vary across the genome. Lastly, the approach of quantifying predictability can help us better understand the mechanisms which drive evolution and how organisms will evolve in response to similar environmental pressures. These results suggest that evolution can be constrained and if we actually replay the tape of life, we could see a considerably similar outcome in biodiversity compared to what Gould predicted.
The Possibility of the Kelvin-Helmholtz Instability during Sedimentation of Dust Grains in the Protoplanetary Disk

description: In this paper, we reexamine the possibility of shear-driven turbulence during sedimentation of dust grains in the protoplanetary disk. The shear-driven turbulence is expected to occur before the onset of the gravitational instability for MMSN model. While according to previous studies without taking account of growth of dust grains, with the larger abundance of dust grains, the gravitational instability is indicated to occur before shear-driven turbulence. In this paper, the case with dust growth is considered, and it is found that the Kelvin-Helmholtz instability tends to occur before the gravitational instability even in the case with large abundance of dust grains. This is different from previous results without the dust growth.

description: L'auteur examine quelques-unes des conséquences de l'extermination des peuples autochtones de l'Uruguay et de l'intégration des survivants à la société de classes post-coloniale. De l'avis général, cette question avait été réglée suite à l'adoption, par l'État uruguayen, d'un profil de pays européen. Or, des épisodes de l'histoire récente mettent sérieusement en cause les mythes associés à cette prétendue homogénéité sociale et culturelle, qui serait le résultat des migrations européennes en Uruguay. Une crise sociale et politique (1973-1984) a mis à l'épreuve le symbolisme et les stéréotypes sociaux de l'Uruguay dit moderne. L’émergence de nouvelles identités indigènes est un processus de construction de la mémoire auquel participent la recherche scientifique sur le passé, la revendication des droits sociaux des descendants et la mise en cause des récits historiques officiels. Au cours de ces dernières années, les approches anthropologiques et patrimoniales ont contribué à rendre plus visible le legs des peuples autochtones. Ce texte a été traduit de l'espagnol par Ana Guarnerio et la révision assurée par Clara Duterme et Ariela Epstein.

description: Residual stresses in components are an important issue in most manufacturing processes, as they influence the performance of the final part. Regarding hot forming processes there is a great potential of defining a targeted residual stress state, due to numerous adjustment parameters like deformation state or temperature profile. In order to ensure appropriate numerical modelling of resulting residual stresses in a thermomechanical process, comprehensive material data regarding phase transformation are required. This paper presents an experimental-numerical procedure to efficiently determine time-temperature-transformation diagrams for cooling simulations after hot forming. The transformation behaviour of the steel alloys 42CrMo4 and 100Cr6 is determined by experiments as well as FE-simulations. Finally, the simulation model is validated by dilatometric experiments and metallographic investigations.

Le point de départ de cette conférence était issu du constat que nous faisions sur nos terrains respectifs – qui relèvent pour Gabriel Gatti d’une approche sociologique comparative et critique de la condition de victime en Europe et en Amérique Latine, et pour Elisabeth Anstett d’une anthropologie des usages politiques et sociaux des restes humains dans les contextes de violences de masse et de génocide – de l’irruption dans l’arène sociale d’un acide, l’Acide Désoxyribonucléique plus connu sous son surnom d’ADN.

description: Bien que reconnaissant la place centrale que le sang a eu, dans la tradition occidentale, en tant que substance déterminante de la parenté, cet article s'arrête sur le cas des maternités lesbiennes pour relativiser – et non nier – la centralité du biologique dans la parenté. Les maternités lesbiennes sont un cas paradigmatique où le sang, dans un sens métonymique du biologique, est remplacé par l'amour comme substance partagée, qui est revendiquée comme la base de toutes les relations parentales et comme « l'origine » du lien familial. Dans le contexte des maternités lesbiennes, le biologique perd de son importance pour laisser place à une conception de la procréation articulée autour de la volonté d'être mère et de l'idée de l'amour générateur de la parentalité. Le paradoxe est que ces femmes, bien qu'elles affirment ne pas avoir besoin du biologique pour être une famille, choisissent pour réaliser leur projet parental essentiellement des technologies reproductives qui manipulent les substances biologiques auxquelles on attribue la capacité de générer la parenté. Le biologique est ensuite resignifié et réinterprété à partir de cette conception du lien parental qui rejette la primauté du biologique.

description: Following previous works regarding electroweak precision tests in supersymmetry, we continue to explore their implications to the MSSM and NMSSM both of which are tightly constrained by the Higgs mass and its decay experiments at the LHC. We adopt universal squark, slepton mass of three generations, and A-term of all SM fermions. We determine the flows of both MSSM and NMSSM in the $S$-$T$ plane with increasing $\tanβ$ and/or $γγ$ rate. Either increasing the value of $R_γ$ or $\tanβ$, we find that the benchmark points tend to be pushed outside the contour at 99% CL in the MSSM, however, conversely they tend to shrink towards to the SM reference point in the NMSSM. In particular, $\tanβ\gtrsim 50$ is excluded at 99% CL by the EWPTs for the MSSM due to this behavior. This behavior is also useful to distinguish the NMSSM from the MSSM. A byproduct is that the contributions coming from the neutralinos and charginos should be more suppressed in the MSSM in comparison with the NMSSM.

description: Les évolutions récentes de la génétique débouchent sur de nouveaux tests ADN dont l’objectif est de prédire l’origine géographique d’un suspect. Cet article analyse la manière dont ces pratiques furent problématisées (au sens de Foucault), en France, entre 2006 et 2014. Tout d’abord, est présenté le lancement de ces tests, montrant le travail des acteurs qui à la fois alimentent les préconditions de la problématisation et cherchent à la déconstruire. L’article poursuit sur la façon dont celle-ci fut exprimée par les opposants aux tests, à travers des interrogations politiques et éthiques sur l’usage de données raciales. Enfin, sont présentées les régulations étatiques à ce sujet, formulées en termes d’interdiction. En conclusion, l’article montre la manière dont la problématisation met en évidence les transformations contemporaines de l’origine et les types de sujets produits.

Exploring partnerships for patients and carers in professional healthcare training

Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: Healthcare educators continue to strive towards aspirations for involving patients as ‘equal partners’ in curriculum design, delivery and management, guided by well-established frameworks proposing a hierarchy of involvement. We do not yet understand what these partnerships mean for all stakeholders and the processes needed to support them. Theory can help to illuminate solutions to these gaps in the evidence-base. This study aimed to understand what it means to key stakeholders to involve patients and carers as ‘equal partners’ within one community of healthcare educators. A qualitative case study design was adopted, underpinned by Communities of Practice theory. Semi-structured interviews were conducted with patients and carers (n=10) and educators (n=10) from across a Medical and a Healthcare School. Five focus groups were held with penultimate-year students (n=20) from across both Schools. Data were analysed using reflexive thematic analysis informed by Communities of Practice theory. The analysis resulted in three overarching themes: Boundaries, Identity and Understanding Partnership. There are boundaries between patients, educators and students in healthcare education which can hinder meaningful patient involvement. Boundaries are marked through differences in knowledge, a lack of shared vision and issues around trust. Stakeholders experience tensions of identity when they come together across boundaries, revealing insights into their construction of the ‘patient’ identity. All stakeholders agreed that ‘equal’ partnerships were neither feasible nor desirable. Instead of being about equality, stakeholders considered that true, meaningful partnerships were about valuing patients and carers at any level of involvement. Applying Communities of Practice theory has, for the first time, illuminated issues of boundary and identity that stakeholders experience when patients and carers are involved in healthcare education. The findings challenge a hierarchical set of steps towards involving patients as ‘equal partners’ in education and deepen understandings of the processes needed to support patient involvement in programme delivery systems.

description: The separation of immiscible liquids has significant implications for magma evolution and the formation of magmatic ore deposits. We combine high-resolution imaging and electron probe microanalysis with the first use of atom probe tomography on tholeiitic basaltic glass from Hawaii, the Snake River Plain, and Iceland, to investigate the onset of unmixing of basaltic liquids into Fe-rich and Si-rich conjugates. We examine the relationships between unmixing and crystal growth, and the evolution of a nanoemulsion in a crystal mush. We identify the previously unrecognised role played by compositional boundary layers in promoting unmixing around growing crystals at melt-crystal interfaces. Our findings have important implications for the formation of immiscible liquid in a crystal mush, the interpretations of compositional zoning in crystals, and the role of liquid immiscibility in controlling magma physical properties.

description: This article describes a practical method for predicting the distribution of electric potential inside an electrical machine’s winding based on design data. It broadens the understanding of winding impedance in terms of inter-winding behavior and allows to properly design an electrical machine’s insulation system during the development phase. The predictions are made based on an frequency-dependent equivalent circuit of the electrical machine which is validated by measurements in the time domain and the frequency domain. Element parameters for the equivalent circuit are derived from two-dimensional field simulations. The results demonstrate a non-uniform potential distribution and demonstrate that the potential difference between individual turns and between turns and the stator core exceeds the expected values. The findings also show a link between winding impedance and potential oscillations inside the winding. Additionally, the article provides an overview of the chronological progression of turn-based models and shows how asynchronous multiprocessing is used to accelerate the solution process of the equivalent circuit.

description: We have studied the energetics, electronic structure, optical excitation, and electron relaxation of dinitromethane molecules (CH$_{2}$N$_{2}$O$_{4}$) adsorbed on semiconducting carbon nanotubes (CNTs) of chiral index (n,0) (n=7, 10, 13, 16, 19). Using first-principles density functional theory (DFT) with generalized gradient approximations and van der Waals corrections, we have calculated adsorption energies of dinitropentylpyrene, in which the dinitromethane is linked to the pyrene via an aliphatic chain, on a CNT. A 75.26 kJ/mol binding energy has been found, which explains why such aliphatic chain-pyrene units can be and have been used in experiments to bind functional molecules to CNTs. The calculated electronic structures show that the dinitromethane introduces a localized state inside the band gap of CNT systems of n=10, 13, 16 and 19; such a state can trap an electron when the CNT is photoexcited. We have therefore investigated the dynamics of intra-band relaxations using the reduced density matrix formalism in conjunction with DFT. For pristine CNTs, we have found that the calculated charge relaxation constants agree well with the experimental time scales. Upon adsorption, these constants are modified, but there is not a clear trend for the direction and magnitude of the change. Nevertheless, our calculations predict that electron relaxation in the conduction band is faster than hole relaxation in the valence band for CNTs with and without molecular adsorbates.

description: The paper at hand deals with the optimization of multisine signals in terms of effective value for identification of electric drive trains, considering constraints on position, velocity, acceleration and torque. The advantage of maximizing the effective value while respecting the constraints rather than minimizing the crest factor of the input signal is delineated. Results with two algorithms suitable for this optimization task are presented for different sets of dynamic constraints. It is shown that the proposed modified clipping algorithm is much faster than the L1 optimization which is dedicated to simultaneous optimization of several different signals, while being slightly less performant in terms of effective value.

title: Development of a PCR for detection and species identification of avian Plasmodium infection in UK penguins
Creators: name: Ings, Katherine Keturah
Publisher: name: University of Glasgow
Year: 2023

description: Avian malaria is a significant cause of mortality in captive penguins in the UK, resulting from infection with apicomplexan protozoa of the genus Plasmodium spread by Culex spp. mosquitos. Detection of disease in penguins is challenging, peracute mortality precedes development of parasitaemia and therefore blood smears are frequently non-diagnostic, whilst post-mortem histopathological diagnosis requires specialist operator knowledge. A test capable of identification and speciation of avian malaria in penguins would allow zoological collections to screen for or confirm infection, and ultimately may guide treatment and prevention strategies. This project aimed to develop a PCR and probe(s) capable of identifying infective Plasmodium species using bioinformatic techniques, and apply these to frozen and formalin fixed paraffin embedded (FFPE) tissues from 25 penguins from the UK with known or suspected avian malaria infection. The novel PCR targeting the Cytochrome B gene demonstrated Plasmodium DNA in both frozen and FFPE penguin tissues. Sanger sequencing of the PCR product indicated 100% (25/25) birds were infected with Plasmodium relictum whilst 4.0% (1/25) birds was coinfected with Plasmodium matutinum. These findings demonstrate potential utility of this PCR in confirming avian malaria infection in penguins, although further validation, including testing on known Plasmodium-negative penguin tissue, is essential. Development of a Plasmodium relictum specific probe targeting the amplicon generated using this protocol was unsuccessful, owing to insufficient interspecies genetic diversity in the target region. In addition, incomplete characterisation of avian infective Plasmodium, geographical diversity and epidemiology of avian malaria parasites compound the challenges inherent in malaria diagnostics.

description: We consider the perturbative treatment of the minimally coupled, massless, self-interacting scalar field in Euclidean de Sitter space. Generalizing work of Rajaraman, we obtain the dynamical mass m^2 \propto sqrt{lambda} H^2 of the scalar for non-vanishing Lagrangian masses and the first perturbative quantum correction in the massless case. We develop the rules of a systematic perturbative expansion, which treats the zero-mode non-perturbatively, and goes in powers of sqrt{lambda}. The infrared divergences are self-regulated by the zero-mode dynamics. Thus, in Euclidean de Sitter space the interacting, massless scalar field is just as well-defined as the massive field. We then show that the dynamical mass can be recovered from the diagrammatic expansion of the self-energy and a consistent solution of the Schwinger-Dyson equation, but requires the summation of a divergent series of loop diagrams of arbitrarily high order. Finally, we note that the value of the long-wavelength mode two-point function in Euclidean de Sitter space agrees at leading order with the stochastic treatment in Lorentzian de Sitter space, in any number of dimensions.

В группе женщин обнаружено развитие сим-птомокомплекса гипогидратации с соответствующими изменениями на молекулярном уровне – сдвигами электролитного, белкового, энергетического, липидного и азотистого обменов, сохранившимися до 7 суток периода восстановления. Ведущими факторами в развитии обнаруженных изменений явились воздействия, не связанные с изоляцией – моделированные нештатные ситуации, особенности питания, режима труда и отдыха. Изменения в группе мужчин были менее выражены и затрагивали меньшее число звеньев обмена веществ.

description: 2007 hat Airbus zum ersten Mal eine GSM-Basisstation ("GSM onBoard") in einer Flugzeugkabine in Betrieb genommen. Wenn solche Systeme aktiv sind, können Passagiere ihre Mobiltelephone und PDAs während des Fluges verwenden. Die Elektromagnetische Verträglichkeit (EMV) wurde u. A. durch im Flugzeug durchgeführte Störfestigkeitstests nach EUROCAE ED-130 [EUROCAE ED-130, Guidance for the Use of Portable Electronic Devices (PEDs) on Board Aircraft, 2006, Malakoff] nachgewiesen. Der weltweite Stand der Standardisierung und insbesondere der Regulierung bevorzugt zur Zeit Tests für den EMV Nachweis. Das ist verständlich, denn als Standards und Regularien entwickelt wurden, gab es sehr wenig Erfahrungswerte aus Tests. Seit 2007 wurden von Airbus viele GSM und ähnliche Systeme installiert und die EMV entsprechend oft durch Tests nachgewiesen. Airbus hat dadurch einen großen Datenbestand der Störfestigkeit von Flugzeugen gegenüber Passagierfunkdiensten aufgebaut. Das Hauptergebnis der vielen Tests ist, dass Flugzeugelektronik unempfindlich gegenüber vom Passagier mitgebrachten elektronischen Geräten ist. Normung und Regulierung sollte darauf reagieren und Test- und Prüfvorschriften anpassen. Eine generelle Präferenz von Tests gegenüber Analysen ist nicht mehr sinnvoll. Testempfehlungen [EUROCAE ED-130, Guidance for the Use of Portable Electronic Devices (PEDs) on Board Aircraft, 2006, Malakoff; RTCA DO-294, Guidance On Allowing Transmitting Portable Electronic Devices (t-peds) On Aircraft, 2008] sollten auf mögliche Vereinfachungen überprüft werden. Ein genereller vereinfachter Nachweis für die Nutzung von Kommunikationsstandards mittlerer Leistung ist zu erwägen.

description: Let $D$ be a strongly connected digraphs on $n\ge 4$ vertices. A vertex $v$ of $D$ is noncritical, if the digraph $D-v$ is strongly connected. We prove, that if sum of the degrees of any two adjacent vertices of $D$ is at least $n+1$, then there exists a noncritical vertex in $D$, and if sum of the degrees of any two adjacent vertices of $D$ is at least $n+2$, then there exist two noncritical vertices in $D$. A series of examples confirm that these bounds are tight.

description: Dieser Beitrag beschreibt einen universellen, messtechnisch verifizierten Ansatz, mit dem EMV-Analysen für oben genannte bzw. sogar beliebige Navigationssysteme in einer verkleinerten Messumgebung mit nahezu uneingeschränkter Flexibilität durchgeführt werden können. Die Skalierung beinhaltet dabei nicht nur das Verkleinern der Reflexionsobjekte selbst, sondern vielmehr die Nachbildung der betroffenen Navigationssysteme bei entsprechend höherer Frequenz; im hier beschriebenen Ansatz für das ILS und das Drehfunkfeuer bei 16 GHz. Die ingenieurtechnische Schwierigkeit besteht in der getreuen Nachbildung der Abstrahlcharakteristik und der eigentlichen Navigationsinformation des Originalsystems.
title: Мониторинг концентрации калия в эякуляте как маркера эффективности тамсулозина у пациентов с хроническим простатитом 3Б

description: Цель работы – методом кластерного анализа проверить гипотезу о том, что отклонение значения KAPLEE от нормального диапазона в сторону уменьшения или в сторону повышения является предиктором меньшей эффективности тамсулозина у пациентов, страдающих от симптомов нижних мочевых путей, ассоциированных с хроническим простатитом 3Б (ХП3Б).

В клиническом исследовании приняли участие 32 пациента с диагнозом «ХП3Б», которые в течение 30 дней перед этим принимали тамсулозин 0,4 мг в сутки в режиме монотерапии. Сначала каждый пациент оценивал эффективность проведенной фармакотерапии в его случае. Эта оценка варьировала от 1 (абсолютная неэффективность) до 5 (абсо-лютная эффективность). Далее пациент собирал эякулят в одноразовый контейнер. Затем определялась концентрация KAPLEE. Таким образом, данные каждого пациента оказывались расположены в двухосевой системе координат: ось абсцисс – значение KAPLEE; ось ординат – оценка эффективности тамсулозина. Затем был проведен кластерный анализ этих данных. Вычислялись центры кластеров, как покоординатные средние кластеров. Тем самым проверялась гипотеза об «обособленном» существовании трех различных кластеров.
Нормальное значение KAPLEE является предиктором высокой эффективности приема тамсулозина пациентами с ХП3Б. Отклонение KAPLEE от нормального диапазона либо в бо́льшую, либо в меньшую сторону является предиктором низкой эффективности тамсулозина при ХП3Б.
Концентрация калия в эякуляте способна быть предиктором эффективности приема тамсулозина при ХП3Б.

description: Изучено влияние основных физических факторов, возникающих в микрополосковых линиях, на импульсные характеристики и сигналы в сверхширокополосных фильтрах. Учтены две группы факторов: частотные зависимости фазовой скорости, затухания и волновых сопротивлений, а также частичное излучение, возникновение высших типов волн и возникновение поверхностной волны. Приведены аналитические выражения, на основе которых разработан прикладной пакет программ. Рассмотрено искажение импульсной характеристики согласованного фильтра и отраженного сигнала в виде автокорреляционной функции.

description: Durch die Vielzahl von Sendeanlagen und die ausgedehnten metallischen Flächen handelt es sich bei Schiffen um komplexe elektromagnetische Umgebungen. Die Anzahl und Art der potentiellen Störquellen ist nur begrenzt vorhersagbar, da z.B. im Fall von Kreuzfahrtschiffen die Passagiere eine Vielzahl elektronischer Systeme (Telefone, Laptops etc.) mitbringen, deren Ort und Betriebsdauer variieren kann. In dieser komplexen Umgebung ist eine zuverlässige und ausfallsichere Kommunikationslösung mit Landstationen im Nahbereich gefordert. Zur Minimierung der Kosten wird dabei auf kostenfrei nutzbare ISM-Bänder zurückgegriffen, die mit anderen Funkdiensten konkurrierend geteilt werden müssen. In dieser Veröffentlichung werden die Auswirkungen der Störungen betrachtet und eine einfache Mehrwegeausbreitungsumgebung simuliert. Aufgrund dieser Betrachtungen wird ein System projektiert, das simultan zwei unterschiedliche Frequenzbereiche zur Datenübertragung verwendet. Durch dieses Verfahren können die Auswirkungen von elektromagnetischen Störungen auf das System minimiert werden. Durch die unterschiedlichen Frequenzen variieren die Interferenzmuster der Mehrwegeausbreitung. Somit ist gewährleistet, dass sich mindestens eine Funkübertragungsstrecke nicht in einer Zone mit destruktiver Interferenz befindet und daher die Übertragung aufrechterhalten werden kann. Das vorgestellte System wird praktisch aufgebaut und im Rahmen einer Schiffsüberführung auf der Ems zur Übermittlung von Wetterdaten erfolgreich eingesetzt.
Fluctuation properties of acoustic phonons generated by ultrafast optical excitation of a quantum dot

description: We study theoretically the fluctuation properties of acoustic phonons created in a semiconductor quantum dot after ultrafast optical excitation. An excitation with a single ultrafast pulse creates an exciton confined to the quantum dot, which is coupled to longitudinal acoustic phonons. This leads to the formation of a polaron in the quantum dot accompanied by the emission of a phonon wave packet. We show that the fluctuations of the lattice displacement associated with the wave packet after a single laser pulse excitation in resonance with the exciton transition are always larger than their respective vacuum values. Manipulating the exciton with a second pulse can result in a reduction of the fluctuations below their vacuum limit, which means that the phonons are squeezed. We show that the squeezing properties of the wave packet strongly depend on the relative phase and the time delay between the two laser pulses.
