description: We introduce an eigenvalue-preserving transformation algorithm from the generalized eigenvalue problem by matrix pencil of the upper and the lower bidiagonal matrices into a standard eigenvalue problem while preserving sparsity, using the theory of orthogonal polynomials. The procedure is formulated without subtraction, which causes numerical instability. Furthermore, the algorithm is discussed for the extended case where the upper bidiagonal matrix is of Hessenberg type.

description: Le opere narrative mostrano un’innata consapevolezza della tensione che deriva dalla necessità di distribuire l’attenzione su diversi personaggi in quantità disomogenee. L’autore si propone di creare un modello teorico per affrontare una serie di questioni legate alle scelte distribuzionali nel romanzo dell’Ottocento. Vengono introdotte le categorie di spazio-personaggio – l’incontro/scontro tra individuo rappresentato e spazio narrativo – e sistema-personaggi – la disposizione di personaggi multipli in una struttura narrativa. Le categorie intendono ovviare alla scissione che ha dominato la critica sul personaggio, divisa tra due posizioni antitetiche: da un lato chi ha ridotto il personaggio a mero accorgimento formale, dall’altro coloro i quali ne hanno enfatizzato l’aspetto referenziale e umano. L’intento delle categorie qui proposte è invece quello di recuperare la dialettica che lega questi due aspetti del personaggio finzionale. In particolare, mettere in evidenza come gli esiti strutturali del romanzo dipendano dal problema di rappresentare personaggi minori ridotti ai due principali paradigmi del bizzaro e del lavoratore. I meccanismi del romanzo e i disequilibri strutturali che derivano dall’incorporazione dei personaggi sono interpretati dall’autore come rispechiamento del difficile rapporto tra diseguaglianza e democrazia, che ha contrassegnato un secolo, l’Ottocento, dove alla mobilità sociale della borghesia faceva da contraltare la marginalizzazione delle classi subalterne. L’intervento si conclude con cenni al trattamento del personaggio nei lavori di Jane Austen, Dickens e Balzac.

description: In a recent paper, motivated by the study of central extensions of associative algebras, G. Janelidze introduces the notion of weakly action representable category. In this paper, we show that the category of Leibniz algebras is weakly action representable and we characterize the class of acting morphisms. Moreover, we study the representability of actions of the category of Poisson algebras by describing explicitly a universal strict general actor.

Accelerated degradation of a polyurethane aerospace coating.
Creators: name: Bozorgzad Moghim, Taraneh
Publisher: name: University of Surrey
Year: 2020

description: Understanding the degradation phenomena of a coating is paramount in determining its service lifetime. A coating may experience a multitude of extreme environments; humidity, temperature and UV radiation, with UV radiation being the acute cause of coating degradation. With aircraft flying at altitudes between 9 and 13 km, their exposure to UV and ozone rise significantly. However, the effects of UV and ozone combined are seldom explored within literature. A polyurethane (PU) military aircraft topcoat was exposed to UV radiation, within a QUV chamber, and to UV/ozone, using a novel method of exposure that was developed herein. To compare the traditional exposure test with the novel approach, the coatings were analysed with x-ray photoelectron spectroscopy (XPS), time of flight secondary ion mass spectrometry (ToF-SIMS) and atomic force microscopy (AFM). Significant degradation is observed within 2 minutes of UV/ozone exposure which equates to 56 days of UV degradation. The main changes observed are the rise of inorganic components with exposure time, as the polymer resin decomposes. The topography also shows an increase in roughness at the microscale level. By combining ToF-SIMS with principal component analysis (PCA) a more detailed analysis of the data can be obtained. PCA analysis enabled the positive identification of cluster ions representing the degradation product as well as the reactant ions. The degradation product was identified to be an azo compound, which enabled a degradation mechanism to be proposed. Using the detail provided by the surface analysis, two successful techniques have been developed for the examination of degradation of in-service coatings through an economic, straight forward device. One, is through the use of a portable ATR-FTIR spectrometer and applying PCA to the collected data. Two, using a more simplistic economic approach, through UV irradiance, where increasing degradation displays greater fluorescence upon UV irradiance.

description: This research aims to assess the practice pattern of Canadian emergency physicians for management of anaphylaxis and investigate the clinical predictors for biphasic reactions in children with anaphylaxis. We conducted two studies: a national survey and a multicenter Health Records (HR) review of emergency department visits. Of the 608 physicians surveyed, 340 (56%) responded. Overall, 211(62%) of the physicians correctly agreed that both hypothetical scenarios in the survey were consistent with anaphylaxis, and 206(61%) chose to administer epinephrine. In our HR review, we found five independent predictors of biphasic reactions: age 6-9 years (OR 3.60; 95% CI 1.5-8.58), time from onset of the anaphylactic reaction to ED presentation >90 minutes (OR 2.58; 95% CI 1.47-4.53), wide pulse pressure at triage (OR 2.92; 95% CI 1.69-5.04), treatment of the reaction with >1 dose of epinephrine (OR 2.7; 95% CI 1.12-6.55), and administration of inhaled salbutamol in ED (OR 2.39; 95% CI 1.24-4.62).

Except for the case of the throughput for the binary tree, all the results are new. We furthermore disprove the claim that only the binary tree maximises throughput. Our method works with many observables and can be used as a blueprint for further analysis.

description: Infertility politics implies a role for the state in regulating the relationships between different parties involved in the medicalized process of reproduction, namely would-be-parents (infertile couples or individuals), gamete donors, surrogate mothers, fertility specialists, etc. Policies adopted by the Canadian federal government in 2004 as regards assisted reproductive technologies (ARTs) were largely inspired by British regulations. Despite this similar start, Canadian policies never lead to implementation; the province of Quebec rapidly contested the federal Assisted Human Reproduction Act before the courts; and many issues of assisted conception were regulated in a heterogeneous manner by the provinces. Meanwhile in Britain, the implementation of the policies created many disparities among the regions of the country; the principle of the law was thoroughly contested and scrutinized; and the sites of deliberation were multiple in spite of the existence of a national regulatory agency. First, the author argues that assisted reproduction technologies cannot be taken as one policy domain, but is an umbrella label for a variety of policy issues. In that context, ARTs are unpacked in order to study, at the system level, the practices related to the overcoming of infertility. I focus on three sub-issues: access to fertility treatments, including the question of public funding and access criteria; gamete and embryo donation, including the question of filiation and donor conceived children’s right to know their biological origins; and surrogacy or the enforcement of pre-natal gestational surrogacy arrangements. Second, by mapping the variety of discourses and arenas mobilized by a range of actors, this study shows how framing and reframing dynamics influence public policies and their implementation. Third, by comparing frame mobilization and discursive dynamics between Quebec, Ontario and England this analysis demonstrates how frame alignment can be a necessary condition for a frame to be performative and influence policy outcomes. Depending on the context in which it occurs, frame transformation, amplification, extension or bridging can induce stability or trigger a cascade of events that will lead to policy change or to a change in the implementation of a policy.
‘Raising Confident Children’: A Feasibility Study of a Brief Intervention for Parents of Children with Long-Term Conditions

Year: 2022

description: Parenting a child with a long-term condition can impact upon the parents’ own well-being as well as their child’s. This thesis aims to explore psychological interventions to support this population.
description: Part one evaluates the feasibility, acceptability and preliminary outcomes of workshops for parents of children with four long-term conditions: asthma, cancer, diabetes (Type I) and food allergy. This workshop aimed to reduce intergenerational transmission of anxiety in the context of the long-term condition. Results suggested that this workshop is acceptable and feasible. Analysis of this workshops preliminary effectiveness also suggest that it can reduce parental anxiety, child anxiety for children aged 6.5-16, and improve quality of life for children aged 8-12.
description: Part two presents a meta-analysis and systematic review of the literature concerning psychological interventions to support parents who have a child with asthma. Results suggest that psychological interventions can improve parents’ sense of self-efficacy, confidence and sense of control in the short term, as well as their emotional distress in both the short and long term. There was no evidence from the meta-analysis that these interventions lead to significant improvements in quality of life or long-term self-efficacy, confidence and sense of control. Tentative conclusions about the reason for this are discussed however further research is required in this area.
Conceptualising agency through the world social forum process: a layered analysis of alternative globalisation
Creators: name: Ramos, Jose M.
Publisher: name: Swinburne
Year: 2024

description: Ulrick Beck's notion of sub-politics, in describing civil society's trans-national responses to the challenges of late industrial capitalism, embodies implicitly the power of civil society and the third sector to create desired social changes within a widening arc of risk horizons. Subsequent to Beck's 1999 writings, we have seen the emergence of the World Social Forum Process, which has become a platform for the global justice / alter-globalisation movement, and has worked as a catalyst in bringing together civil society / the community sector into new meta-networks, in order to address such meta-problems. A primary question explored in this paper is how communities address the large scale global challenges of neo-liberalism turn neo-conservatism, through a globalisation from below. This paper addresses this question through an examination of the World Social Forum Process as complex agent of social change, arguing that the World Social Forum is a platform for social innovation, which can be seen through a 'layered complexity' perspective. Causal Layered Analysis, and complex adaptive socio-ecological systems perspectives, offer layered frameworks that can be used to understand the World Social Forum Process as platform for social innovations. From this view Social Forums can be seen to be platforms for fast moving resistance, to deeper policy, law and institutional innovations, and on to even deeper worldview shifts, epistemological reconstructions (the epistemology of the Global South), and a culture of 'horizontalism', and through to the emergence of deep narratives for a Global Commons, people's power and building a planetary society, paralleled by new myths and metaphors. Using this approach, Beck's notion of sub-politics is expanded, as the construction of a cosmopolitan world order takes on a multi-causal and multi-temporal dynamic.
Energy efficient indoor wireless transmission techniques or visible light communication.
Creators: name: Dawoud, Diana W.
Publisher: name: University of Surrey
Year: 2020

description: In visible light communication systems, the intensity modulation/direct detection channel inherently restricts the transmitted signal to be unipolar (nonnegative only) and incoherent. Those restrictions limit the types of transceivers that can be used in visible light communication systems; indeed, the intensity modulation/direct detection transceivers can be readily utilized, whereas classic radio frequency methods (e.g., schemes such as pulse amplitude modulation, quadrature amplitude modulation and orthogonal frequency division multiplexing) require adjustments that reduce their conventional efficiency. A continuous effort has been made to adapt radio frequency transceiver techniques to visible light communication; however, up to date, the proposed solutions came at the expense of the energy efficiency of the systems. In turn, it severely affects the bit error rate performance of the system. In light of this, the topic of this thesis is to design energy efficient transmission schemes to expand the set of legacy radio frequency modulation methods that can be efficiently used in visible light communication systems. Thus, the first contribution of this dissertation is a unipolar transmission technique that allows conveying bipolar symbols through the intensity modulation/direct detection channel without severely consuming the amount of transmit power. The second contribution is proposing a new technique to simultaneously transmit the two parts of two-dimensional signals over the intensity modulation/direct detection channel. The schemes are proposed with the objective of minimizing the transmitted power and reducing the direct current component of two-dimensional transmit signals by relying on multi-waveform transmission techniques, and, in turn, providing a high-energy efficient transmission scheme for two-dimensional signals. The third contribution is a low complex multi-input multi-output system capable of transmitting unipolar two-dimensional signals. Finally, the error rate expressions of our proposed transceivers in this work are derived, and the performance gains of the proposed schemes are evaluated through Monte-Carlo simulations. The findings show that our schemes could enhance the energy efficiency of the existing transmission techniques in visible light communication systems.

description: Despite evidence to support physically active and passive leisure as significant contributors to well-being, for working mothers, fitting leisure into an already busy schedule can be challenging. The purpose of this study was to examine the influence of perceived time constraints and self-determination for physically active and passive leisure on conflict between these two leisure domains and the influence of this conflict on well-being among physically active working mothers. A total of 66 women who were physically active, worked at least 30 hours per week outside the home and had at least one child living in the home, participated in the study. At baseline, the participants completed a basic intake assessment in addition to validated questionnaires to measure time constraints and motivation for physically active and passive leisure. A two-week period of electronic experience sampling followed to evaluate leisure engagement. A final set of measures to evaluate conflict between physically active and passive leisure over the two weeks, and general well-being were completed at the end of the experience sampling period. Results indicated that despite relatively high levels of satisfaction with time available for both physically active and passive leisure, perceived time constraints were associated with increased goal conflict as are non-self-determined motivation for physically active leisure and self-determined motivation for passive leisure. Controlling for engagement in physically active and passive leisure, well-being is negatively influenced by goal conflict. Recommendations are provided regarding areas for additional research to further our understanding of the impact of opposing motivational orientations on goal conflict including the incorporation of Vallerand’s Dualistic Model of Passion (Vallerand et al., 2003). From a practical standpoint, the implications of the study results for interventions designed to address general well-being in middle class working mothers through targeting factors related to time constraints and goal conflict are discussed.
Re-assessing Criminal Responsibility: A Pragmatic View of the Self
Creators: name: Field, Andrew Frederick
Publisher: name: University of Surrey
Year: 2023

description: This thesis begins by arguing that hard indeterminism, a type of free-will skepticism (FWS), is the most defensible position within the free-will debate. Its competitors, libertarianism (both types: agent-causal and event-causal) and compatibilism fail for the following reasons. Agent-causal libertarianism succumbs to the problem of wild coincidences, and event-causal libertarianism falls foul of the disappearing agent objection. I distinguish between “leeway” and “source” compatibilism whereby the former asserts that a necessary condition for an agent to be morally responsible is to have alternative possibilities (“the agent could have done otherwise”), whilst the latter rejects this. “Leeway” compatibilism is refuted by the consequence argument, and “source” compatibilism is susceptible to the manipulation argument, on the proviso that a free-will skeptic can refute the “no generalisation” objection to the manipulation argument (MA), which it currently fails to do. I present a novel response to the “no generalisation” objection by arguing that to overcome it, the FWS needs to stretch the four-case MA to five cases, including a fifth case termed “the heritability case.” I then investigate the leading criminal punishment model on behalf of the FWS, the quarantine model of criminal punishment model, and argue that its implementation is likely to offer less than adequate deterrence. Due to this, the quarantine model is unlikely to reach democratic legitimacy and would thereby be detested by “the people”. Lastly, from these insights, I develop an original criminal punishment model on behalf of the free-will skeptic that I term “an integrative punishment model.” The integrative punishment model attempts to achieve democratic legitimacy by accommodating the “the people's” desire for vengeance, whilst “capping” the amount of punishment received by criminals, and lessening criminal sentences at the same time since I believe that no-one is ever morally responsible in a desert-based sense.
Selective Oxidation of Lignin Models and Extracts with Earth-Abundant Transition Metals and Hypervalent Iodine

description: As a significant component of lignocellulosic biomass, lignin represents a potential source of value-added aromatic chemicals. In this thesis, catalytic systems with earth-abundant metal catalysts such as molybdenum(VI) and hypervalent iodine complexes were developed to selectively break down lignin models into lower molecular weight chemicals under mild conditions. Due to the complexity of lignin, simple lignin model substrates (A to E), representing common linkages in lignin, were used to investigate the catalytic activity/selectivity of these catalysts. With the molybdenum catalysts [7– 11]/SPC/Adogen®464 system (SPC = sodium percarbonate), oxidation of simple β-1 model compound A in acetonitrile showed primarily C-H bond cleavage to form the ketone product, benzoin methyl ether, whereas the Cα-Cβ bond cleavage product, methyl benzoate, was obtained by switching the reaction solvent to benzonitrile. Preference for generating the Cα-Cβ bond cleavage product, i.e. benzaldehyde, can also be achieved with other early to middle transition metal catalysts using H2O2(aq) as the terminal oxidant. Stoichiometric amounts of hypervalent iodine/Lewis acid systems [20a-c] were able to selectively cleave Cα-Cβ bonds to aldehydes with both simple β-1 model compound A and β-O-4 model compound C. In contrast, other lignin model compounds with different linkages were unable to be oxidized to a great extent using these Mo- or iodine-based complexes. The catalytic activity and selectivity of the reported vanadium complexes, copper salts and non-metal system 1-5 on non-volatile organosolv (NVO) lignin was investigated under basic condition. Details of the depolymerisation of lignin were determined by using Gel Permeation Chromatography (GPC) and the two-dimensional NMR technique, quantitative HSQC (q-HSQC) spectroscopy. Vanadium [2] and copper systems were found to be the most active for depolymerization of NVO lignin.

description: Studies of adaptive governance in social-ecological systems have identified common features that assist social actors in responding to environmental pressures. Among these features, multiple sources of ecological knowledge, trust, and networks between actors have been highlighted as properties that contribute to successful governance arrangements. However, studies in adaptive governance have also been critiqued using a political ecology approach. This is due to their under-theorization of political elements that can constrain or promote the formation of the features of adaptive governance. In particular, power dynamics between actors and the subsequent privileging of one source of knowledge over another might have an effect on governance arrangements. In China, environmental degradation is a serious issue. The Qinhuai River, located in the city of Nanjing, has experienced significant ecological decline over the last 30 years as urbanization pressures on the system increased. Over the same period, China has undergone changes in state-society relations, including allowing the formation of NGOs. Since the turn of the millennium, several NGOs have begun working on issues related to the Qinhuai River, including raising awareness and producing information on the environment. This study examines the features of adaptive governance in a critical light by situating them in the local political context of China. The relationship between NGOs, fishers who use the Qinhuai River and government are examined using Social Network Analysis and semi-structured interviews in order to understand the production of information, networking and trust between these actors. It is shown that the existing arrangements to include NGOs and fishers in the river’s governance activities are guided by a corporatist system of state-sanctioned representation. This is not conducive to adaptive governance arrangements, despite the increasing existence of ENGO networks and new sources of knowledge over the last decade. It is thus important that studies of adaptive governance take steps to contextualize their findings within the local political climate.

description: The first part of my thesis is about the existence of training in the family planning context, along with some problems of current training. The second part is about the theories and principles of adults as learners that will be useful and applicable in the training program. The third part is about the process of how learning is encouraged in certain circumstances that may achieve a participant's needs and expectations. In my conclusion I tried to put some emphasis on how the practitioners who are always involved in training should be and some recommendations that might be useful for them. In the last part, I attempt to design a training program for the practitioners concerning the philosophy of training in Family Planning Program, adult learning, and the techniques of training. The follow up of my thesis will respond to the basic problem of training in Family Planning in North Sulawesi.

description: Extracting fine-grained features such as styles from unlabeled data is crucial for data analysis. Unsupervised methods such as variational autoencoders (VAEs) can extract styles that are usually mixed with other features. Conditional VAEs (CVAEs) can isolate styles using class labels; however, there are no established methods to extract only styles using unlabeled data. In this paper, we propose a CVAE-based method that extracts style features using only unlabeled data. The proposed model consists of a contrastive learning (CL) part that extracts style-independent features and a CVAE part that extracts style features. The CL model learns representations independent of data augmentation, which can be viewed as a perturbation in styles, in a self-supervised manner. Considering the style-independent features from the pretrained CL model as a condition, the CVAE learns to extract only styles. Additionally, we introduce a constraint based on mutual information between the CL and VAE features to prevent the CVAE from ignoring the condition. Experiments conducted using two simple datasets, MNIST and an original dataset based on Google Fonts, demonstrate that the proposed method can efficiently extract style features. Further experiments using real-world natural image datasets were also conducted to illustrate the method's extendability.

description: The current coronavirus disease 2019 (COVID-19) pandemic is impacting the way in which dental services are provided. The aim of this narrative review was twofold: to summarize key areas from the Canadian protocols available for the reopening and restructuring of dental services across the country and to critically review these protocols based on existing evidence. A narrative review of the existing Canadian protocols, written in English and French, was undertaken between April 15 and July 13, 2020. The protocols were obtained by searching through regulatory bodies and websites from professional organizations, and from personal contacts through academic institutions and policy leaders. The data extraction form focused only on protocols related to dentistry, and the information was compiled by a hired assistant. Content was categorized via group discussions with the research team on eight areas: office management and procedures, patient and staff screening, treatment procedures, office layout, risk reduction, personal protective equipment, supporting information, and length and readability. Thirteen protocols were identified and offered substantial variation in the level of details provided. All but two protocols specified proper donning/doffing of personal protective equipment, while all protocols recommended daily monitoring of COVID-19 related signs and symptoms in staff and patients. They varied in terms of recommended mask types, eye and face shield protection, and head coverings. While all protocols aimed at restructuring emergency dental services, their recommendations were often not based on the published evidence. This narrative review summarized key areas from 13 provincial and territorial protocols in Canada to help oral health care providers plan the reopening of their services. The information conveyed across all documents was clear, but variance highlights the need for a coordinated effort to develop an evidence-based document for dental practitioners.

description: Solid-state nuclear magnetic resonance (SSNMR) has proven to be a useful tool in the characterization of non-covalent interactions such as hydrogen bonding and cation-π interactions. In recent years, the scientific community has manifested a renewed interest towards an important class of non-covalent interaction, halogen bonding (XB), as it has applications in various fields such as crystal engineering and biological processes. This dissertation demonstrates that NMR parameters measured in the solid state are sensitive to changes in electronic structure, which are caused by halogen bonds. A series of halogen bonded compounds exhibiting interactions between different diiodoperfluorobenzenes (p- C6F4I2, o- C6F4I2, sym- C6F3I3, p- C6H4I2) and various halogen bond acceptors have been synthesized as part of this work. These new halogen bonded compounds were characterized with a combined theoretical and experimental SSNMR, X-ray diffraction (XRD) methods. The complete multinuclear magnetic resonance spectroscopy of the nuclei involved directly in the halogen bond (13C, 14/15N, 31P, 77Se, 35/37Cl and 79/81Br) were recorded at multiple magnetic fields (4.7, 9.4, 11.75 and 21.1 T). The specialized SSNMR experiments provided high-resolution spectra of quadrupolar nuclei, which were WURST-QCPMG or solid-echo type experiments combined with the variable offset cumulative spectral (VOCS) method, as for spin 1/2 nuclei cross polarization magic angle spinning (CPMAS) experiments were usually appropriate. This dissertation will discuss successful applications of SSNMR spectroscopy to characterize halogen bonds, it will demonstrate the significant changes in NMR observables in the presence of XB interaction and thus establish that NMR parameters are very sensitive to halogen bonding interaction. Furthermore, this work explains why the NMR parameters are correlated with the halogen bonding interaction. The different trends observed between the NMR observables and the halogen bonding were further understood with a ZORA-DFT natural localized molecular orbital (NLMO) study.

description: Tongue is the most important articulator of speech. Given the dominant role of speech in human interactions, a large proportion of the research on tongue movement focuses on its role in speech, specifically vowel production. A three-dimensional (3D) tongue model could provide important visual information that would help an individual to correct the tongue position during speech. Researchers have been tried using different imaging techniques such as MRI, CT and Ultrasound imaging to capture the tongue information. Among them ultrasound imaging is, recently, getting popular in the field of linguistic, phonetic research and medical imaging. Having access to real-time display of the movement of the tongue, non-invasive measurement with relatively cheap equipment and also avoiding risks of x-rays or other types of radiation made us use this method for capturing set of required data. We introduce a new method of reconstructing the 3D generic tongue model. The novelty of our method is employing only two ultrasound images for tongue reconstruction purpose. We presented a feature-based deformation method that could represent the different shapes of the tongue during speech with no computationally expensive requirements. Tongue is a difficult target for deformation due to its muscle complexity. The fact that tongue is concealed in the oral cavity can also provide additional challenges to capture the whole image of it using available methods such as MRI, X-Ray and ultrasound imaging. We overcome these difficulties by: (a) Analysis of tongue surface data using ultrasound imaging; Capturing tongue shape and tracking the tongue surface data for different sets of pronunciations from obtained ultrasound images (b) Deformation of 3D generic tongue model using deformation method named Radial Basis Functions(RBFs) based on two orthogonal (side and front view) ultrasound images. We tested our methodology on a set of Ultrasound images received from Department of linguistics. We selected different sample of Ultrasound frames from a set of mid-coronal and corresponding mid-sagittal images. The Ultrasound data is collected while a male person was pronouncing 1 to 10 and then sustained "i", "u", "e", "o", "a", "s", "sh", "l", "n", and "r". Our model is capable of representing tongue shapes during the production of vowels and also the general motion of tongue. A set of control points of the 3D tongue neutral model, allows each tongue segment to be easily captured. In order to test the capability and sufficiency of the proposed method in terms of deformation, we have compared our results (deformed tongue models based on arbitrary set of control points on mid-sagittal and the mid-coronal line of the 3D tongue model) with the results from an open-source tongue simulation system named “Artisynth” (deformed tongue models obtained from different activations of tongue muscles).

description: Blood-derived circulatory angiogenic cells (CACs) and resident cardiac stem cells (CSCs) have both been shown to improve cardiac function after myocardial infarction (MI) but the superiority of either cell type has long been an area of speculation with no definitive head-to-head trial. In this study, we compared the paracrine profile of human CACs and CSCs, alone or in combination. We characterized the therapeutic ability of these cells to salvage myocardial function in an immunodeficient mouse model of MI by transplanting these cells as both single and dual cell therapies seven days after experimental anterior wall MI. CACs and CSCs demonstrated unique paracrine repertoires with equivalent effects on angiogenesis, stem cell migration and myocardial repair. Combination therapy with both cell types synergistically improves post infarct myocardial function greater than either therapy alone. This synergy is likely mediated by the complementary paracrine signatures that promote revascularization and the growth of new myocardium.

description: Let $π$ and $π'$ be cuspidal automorphic representations of $\mathrm{GL}(n)$ and $\mathrm{GL}(n')$ with unitary central characters. We establish a new zero-free region for all $\mathrm{GL}(1)$-twists of the Rankin-Selberg $L$-function $L(s,π\timesπ')$, generalizing Siegel's celebrated work on Dirichlet $L$-functions. As an application, we prove the first unconditional Siegel-Walfisz theorem for the Dirichlet coefficients of $-L'(s,π\timesπ')/L(s,π\timesπ')$. Also, for $n\leq 8$, we extend the region of holomorphy and nonvanishing for the twisted symmetric power $L$-functions $L(s,π,\mathrm{Sym}^n\otimesχ)$ of any cuspidal automorphic representation of $\mathrm{GL}(2)$.

Assessment of metabolomic changes in chemotherapy-induced peripheral neuropathy

description: Chemotherapy-induced peripheral neuropathy (CIPN) has long represented one of the most relevant neurological side effects of oncological therapies. Nevertheless, despite the progress in drug regimens, the occurrence of troublesome adverse events still affects the efficacy of antineoplastic therapy, leading to the reduction or discontinuation of the treatment. Paclitaxel is an anti-tubulin drug which has emerged as an efficacious antitumor agent in the treatment of different cancers. However, its clinical use is often limited by the onset of paclitaxel-induced peripheral neuropathy (PIPN). Numerous alterations related to aging have been hypothesized to underlie age-related susceptibility to nerve damage. Nevertheless, the results of these studies are inconclusive and other targets, which might be used as potential biomarkers of nerve impairment, deserve to be considered. On these bases, the aim of our study was to investigate the age-related effects of paclitaxel treatment on the peripheral nervous system, and the metabolic changes that might be induced by paclitaxel administration at different ages. Our project included neurotoxicity experiments based on neurophysiological, behavioral and histopathological evaluations to assess age-related chemotherapy-induced phenotypic alterations in a neuropathic model of PIPN. We additionally investigated through a targeted Ultra-Performance Liquid Chromatography-Mass Spectrometry (UPLC-MS) based metabolomics approach differences in the plasma and liver metabolite profiles in order to identify potential biomarkers of PIPN development and progression, according to age. Our results suggest that age might be a potential risk factor for more severe CIPN, and should be considered in future studies in order to tailor the chemotherapy regimen and dosage on individual susceptibility of older cancer patients. Our study also identifies for the first time multiple related metabolic axes involved in paclitaxel-induced neurotoxicity, as promising molecular and therapeutic targets in PIPN.
