description: This paper is devoted to abelian varieties arising from generalized Legendre curves. In particular, we consider their corresponding Galois representations, periods, and endomorphism algebras. For certain one parameter families of 2-dimensional abelian varieties of this kind, we determine when the endomorphism algebra of each fiber defined over the algebraic closure of $\Bbb Q$ contains a quaternion algebra.

description: Let $Γ$ be a one-ended, torsion-free hyperbolic group and let $G$ be a semisimple Lie group with finite center. Using the canonical JSJ splitting due to Sela, we define amalgam Anosov representations of $Γ$ into $G$ and prove that they form a domain of discontinuity for the action of $\mathrm{Out}(Γ)$. In the appendix, we prove, using projective Anosov Schottky groups, that if the restriction of the representation to every Fuchsian or rigid vertex group of the JSJ splitting of $Γ$ is Anosov, with respect to a fixed pair of opposite parabolic subgroups, then $ρ$ is amalgam Anosov.

description: Cervical cancer is the fourth most common cancer in women worldwide. More than 90% of cases are caused by the human papillomavirus (HPV). Vaccines developed only guard against a few HPV types and do not protect people who have already been infected. HPV is a small DNA virus that infects the basal layer of the stratified epithelium of the skin and mucosa through small breaks and replicates as the cells differentiate. The mucosal types of HPV can be classified into low-risk and high-risk groups, based on their association with cancer. Among HPV types in high-risk group, HPV type 16 (HPV-16) is the most common, causing 50% of all cancer cases. HPV infection can occur as transient or persistent infections, based on the ability of immune system to clear the virus. Persistent infection is characterized by the integration of HPV genome. HPV-16 exhibits a different integration pattern, with only 50% reported to be integrated at the carcinoma stage. Replication of the HPV genome depends on protein E1, an ATP-dependent helicase. E1 is essential for the amplification of the viral episome in infected cells. Previous studies have shown that E1 does not only act as a helicase protein but is also involved in recruiting and interacting with other host proteins. E1 has also been deemed to drive host cell proliferation. Recent studies have emphasized the emerging role of HPV E1 in cervical carcinogenesis. In this review, a possible mechanism by which E1 drives cell proliferation and oncogenesis will be discussed.

description: We have performed a calculation of the $γp \to π^+ π^- p$ reaction, where the two pions have been separated in $D$-wave producing the $f_2(1270)$ resonance. We use elements of the local hidden gauge approach that provides the interaction of vector mesons in which the $f_2(1270)$ resonance appears as a $ρ$-$ρ$ molecular state in $L=0$ and spin 2. The vector meson dominance, incorporated in the local hidden gauge approach converts a photon into a $ρ^0$ meson and the other meson connects the photon with the proton. The picture is simple and has no free parameters, since the parameters of the theory have been constrained in the previous study of the vector-vector states. In a second step we introduce new elements, not present in the local hidden gauge approach, adapting the $ρ$ propagator to Regge phenomenology and introducing the $ρNN$ tensor coupling. We find that both the differential cross section as well as the $t$ dependence of the cross section are in good agreement with the experimental results and provide support for the molecular picture of the $f_2(1270)$ in the first baryonic reaction where it has been tested.

description: BACKGROUND: Government nutritional welfare support from the English 'Healthy Start' scheme is targeted at low-income pregnant women and preschool children, but take-up of its free food vouchers is much better than its free vitamin vouchers. While universal implementation probably requires a more extensive scheme to be cost-effective, the everyday experience of different ways of receiving or facilitating Healthy Start, especially via children's centres, also requires further evidence. This study therefore aimed to explore (in the context of low take-up levels) perceptions of mothers, health professionals, and commissioners about Healthy Start vitamin and food voucher take-up and compare experiences in a targeted and a universal implementation-area for those vitamins. METHODS: Informed by quantitative analysis of take-up data, qualitative analysis focused on 42 semi-structured interviews with potentially eligible mothers and healthcare staff (and commissioners), purposively sampled via children's centres in a similarly deprived universal and a targeted implementation-area of North West England. RESULTS: While good food voucher take-up appeared to relate to clear presentation, messaging, practicality, and monetary (albeit low) value, poor vitamin take-up appeared to relate to overcomplicated procedures and overreliance on underfunded centres, organizational goodwill, and families' resilience. CONCLUSION: Higher 'universal' vitamin take-up may well have reflected fewer barriers when it became everyone's business to be vitamin-aware. Substantive Healthy Start reform in England (not just cosmetic tinkering) is long overdue. Our study highlights that 'policy, politics, and problem' should be aligned to reach considerable unmet need.

description: We study the model theory of countable right-angled buildings with infinite residues. For every Coxeter graph we obtain a complete theory with a natural axiomatisation, which is $ω$-stable and equational. Furthermore, we provide sharp lower and upper bounds for its degree of ampleness, computed exclusively in terms of the associated Coxeter graph. This generalises and provides an alternative treatment of the free pseudospace.

description: In the present paper we develop an algorithm for all spherically symmetric anisotropic charged fluid distribution. Considering a new source function $ν(r)$ we find out a set of solutions which is physically well behaved and represent compact stellar models. A detailed study specifically shows that the models actually correspond to strange stars in terms of their mass and radius. In this connection we investigate about several physical properties like energy conditions, stability, mass-radius ratio, electric charge content, anisotropic nature and surface redshift through graphical plots and mathematical calculations. All the features from these studies are in excellent agreement with the already available evidences in theory as well as observations.

Large Interval Limit of Rényi Entropy At High Temperature

Year: 2014
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In this paper, we propose a novel expansion to compute the large interval limit of the Rényi entropy of 2D CFT at high temperature. Via the replica trick, the single interval Rényi entropy of 2D CFT at finite temperature could be read from the partition function on $n$-sheeted torus connected with each other along a branch cut. We calculate the partition function by inserting a complete basis across the branch cut. Because of the monodromy condition across the branch cut in the large interval limit, the basis of the states should be the ones in the twist sector. We study the twist sector of a general module of CFT and find that there is an one-to-one correspondence between the twist sector states and the normal sector states. As an application, we revisit the non-compact free scalar theory and discuss the large interval limit of the Rényi entropy of this theory by using our proposal. We find complete agreement in the leading and next-leading orders with direct expansion of the exact partition function. Moreover, we prove the relation (\ref{th}) between thermal entropy and the entanglement entropy for a generic CFT with discrete spectrum.

description: Seed persistence in the soil is crucial for population dynamics. Interspecific differences in soil seed mortality could be a mechanism that may stimulate species coexistence in herbaceous plant communities. Therefore, understanding the levels and causes of seed persistence is vital for understanding community composition and population dynamics. In this study, we evaluated the burial depth as a significant predictor of the temporal dynamics of soil seed persistence. We suppose that species differ in this temporal dynamics of soil seed persistence according to burial depth. Furthermore, we expected that burial depth would affect soil seed persistence differently concerning the species-specific type of dormancy, light, and fluctuating temperature requirements for germination. Seeds of 28 herbaceous species of calcareous grasslands were buried in the field into depths of 1, 5, and 10 cm under the soil surface. Seed viability was tested by germination and tetrazolium tests several times for three years. Species-specific seed traits—a type of dormancy, light requirements and alternating temperature requirements for germination, and longevity index—were used for disentangling the links behind species-specific differences in soil seed persistence. Our study showed differences in soil seed persistence according to the burial depth at the interspecific level. Generally, the deeper the buried seeds, the longer they stayed viable, but huge differences were found between individual species. Species-specific seed traits seem to be an essential determinant of seed persistence in the soil. Seeds of dormant species survived less and only dormant seeds stayed viable in the soil. Similarly, seeds of species without light or alternating temperature requirements for germination generally remained viable in the soil in smaller numbers. Moreover, seeds of species that require light for germination stayed viable longer in the deeper soil layers. Our results help understand the ecosystem dynamics caused by seed reproduction and highlight the importance of a detailed long-term investigation of soil seed persistence. That is essential for understanding the fundamental ecological processes and could help restore valuable calcareous grassland habitats.

description: The extensive application of antibiotics in human and veterinary medicine has led to their widespread occurrence in a natural aquatic environment. Global health crisis is associated with the fast development of antimicrobial resistance, as more and more infectious diseases cannot be treated more than once. Sulfamethoxazole, trimethoprim and ciprofloxacin are the most commonly detected antibiotics in water systems worldwide. The persistent and toxic nature of these antibiotics makes their elimination by conventional treatment methods at wastewater treatment plants almost impossible. The application of advanced oxidation processes and heterogeneous photocatalysis over TiO2 -based materials is a promising solution. This highly efficient technology has the potential to be sustainable, cost-efficient and energy-efficient. A comprehensive review on the application of various TiO2 -based photocatalysts for the degradation of sulfamethoxazole, trimethoprim and ciprofloxacin is focused on highlighting their photocatalytic performance under various reaction conditions (different amounts of pollutant and photocatalyst, pH, light source, reaction media, presence of inorganic ions, natural organic matter, oxidants). Mineralization efficiency and ecotoxicity of final products have been also considered. Further research needs have been presented based on the literature findings. Among them, design and development of highly efficient under sunlight, stable, recyclable and cost-effective TiO2 -based materials; usage of real wastewaters for photocatalytic tests; and compulsory assessment of products ecotoxicity.

description: We show that the ratio between the stellar mass of central galaxy and the mass of its host halo, $f_c \equiv M_{*,c}/M_{\rm h}$, can be used as an observable proxy of halo assembly time, in that galaxy groups with higher $f_c$ assembled their masses earlier. Using SDSS groups of Yang et al., we study how $f_c$ correlates with galaxy properties such as color, star formation rate, metallicity, bulge to disk ratio, and size. Central galaxies of a given stellar mass in groups with $f_c>0.02$ tend to be redder in color, more quenched in star formation, smaller in size, and more bulge dominated, as $f_c$ increases. The trends in color and star formation appear to reverse at $f_c<0.02$, reflecting a down-sizing effect that galaxies in massive halos formed their stars earlier although the host halos themselves assembled later (lower $f_c$). No such reversal is seen in the size of elliptical galaxies, suggesting that their assembly follows halo growth more closely than their star formation. Satellite galaxies of a given stellar mass in groups of a given halo mass tend to be redder in color, more quenched in star formation and smaller in size as $f_c$ increases. For a given stellar mass, satellites also tend to be smaller than centrals. The trends are stronger for lower mass groups. For groups more massive than $\sim 10^{13}{\rm M}_\odot$, a weak reversed trend is seen in color and star formation. The observed trends in star formation are qualitatively reproduced by an empirical model based on halo age abundance matching, but not by a semi-analytical model tested here.

description: La condivisione dell’emozione non è forse cià che anima la comunicazione tra gli esseri umani? La tecnologia, oggi, propone di ridurne la finezza riconducendola all’informazione. E’ il caso di pharmaphone, che ci invita a “condividere” facendo a meno di parlare. Condividiamo ancora qualcosa in questo caso? Questa domanda ci accompagna nel terreno fertile dell’adolescenza. Grazie al nostro metodo del “récit de vie”, ci immergiamo nei ricordi degli adolescenti. Essi preferiscono talune emozioni, cercano di evacuarne altre. Non è che l’inizio! L’imbarazzo sorge da questa inchiesta in cui studiamo ciò che viene evitato, temuto, anticipato. Questo contributo è infatti di ordine metodologico: come siamo arrivati a questo? Il “récit de vie” favorisce la parola dell’adolescente, lasciando che l’inatteso si produca fino ad arrivare all’imbarazzo.

description: Matrix metalloproteinase (MMP)-7, unlike many MMPs, is typically expressed in epithelial cells. It has been linked to epithelial responses to infection, injury, and tissue remodeling including the progression of a number of cancers. We have now examined how MMP-7 expression changes in the progression to esophageal adenocarcinoma (EAC), and have studied mechanisms regulating its expression and its functional significance. Immunohistochemistry revealed that MMP-7 was weakly expressed in normal squamous epithelium adjacent to EAC but was abundant in epithelial cells in both preneoplastic lesions of Barrett's esophagus and EAC particularly at the invasive front. In the stroma, putative myofibroblasts expressing MMP-7 were abundant at the invasive front but were scarce or absent in adjacent tissue. Western blot and ELISA revealed high constitutive secretion of proMMP-7 in an EAC cell line (OE33) that was inhibited by the phosphatidylinositol (PI) 3-kinase inhibitor LY294002 but not by inhibitors of protein kinase C, or MAP kinase activation. There was detectable proMMP-7 in cultured esophageal myofibroblasts but it was undetectable in media. Possible metabolism of MMP-7 by myofibroblasts studied by proteomic analysis indicated degradation via extensive endopeptidase, followed by amino- and carboxpeptidase, cleavages. Myofibroblasts exhibited increased migration and invasion in response to conditioned media from OE33 cells that was reduced by MMP-7 knockdown and immunoneutralization. Thus, MMP-7 expression increases at the invasive front in EAC which may be partly attributable to activation of PI 3-kinase. Secreted MMP-7 may modify the tumor microenvironment by stimulating stromal cell migration and invasion.

description: La (re)integrazione delle emozioni nel campo dell’accettabile, ovvero del desiderabile, funziona come un senso comune da qualche decennio. Nel mio intervento sollevo la questione della portata semantica dell’espressione emozionale nei media sociali, considerati dal punto di vista di una costruzione sociale che influisce sulla lettura del mondo in quanto terreno di condivisione che genera nuove rappresentazioni e costruzioni. Un primo asse di riflessione interroga l’effetto interpretativo della selettività comunicazionale dei contenuti e campi emozionali. Un secondo asse interroga in questa ottica il collettivo e il rapporto all’Altro. Il terzo asse affronta infine il valore e la portata semantica dei marcatori di affetto nei media on line e al di là di essi, rivolgendosi più specificatamente verso le tecno-emozioni e il design affettivo nei social networks.

description: Individuals with chronic pain commonly report significant functional impairment and reduced quality of life. Despite this, little is known about psychological processes and mechanisms underpinning enhancements in well-being within this population. The study aimed to investigate whether (1) increased levels of pain intensity and interference were associated with lower levels of mental well-being, (2) increased positive goal engagement was associated with higher levels of mental well-being and (3) whether the relationships between pain characteristics and mental well-being were mediated by increased positive goal engagement. A total of 586 individuals with chronic pain participated in the cross-sectional, online study. Participants completed self-report measures to assess pain intensity and interference, mental well-being and goal motivation variables. Results showed that pain interference and positive goal engagement were associated with mental well-being. Moreover, the relationship between pain interference and mental well-being was partially mediated by positive goal engagement. The results provide tentative evidence for the protective role of positive goal engagement in enabling individuals with chronic pain to maintain a sense of mental well-being. The study develops the biopsychosocial model of chronic pain by examining the roles and relationships of relevant yet previously unexplored psychological constructs. The promotion of mental well-being through the enhancement of positive goal engagement is discussed, offering a platform for further research and clinical interventions.

description: La questione migratoria è diventata centrale nel dibattito politico, in particolare a partire dagli anni 1970-80. Tra i protagonisti di questo dibattito si impongono oggi i movimenti anti-migranti, che giocano un ruolo molto importante facendosi vettori del rigetto del fenomeno migratorio. A Calais il collettivo anti-migranti ha condotto tra il 2013 e il 2016 una attività sostenuta. Le loro pubblicazioni Facebook, ancorate in ciò che designeremo come « discorso dell’odio »  (« hate speech »), giocano un ruolo importante nella comunicazione e nell’inquadramento della loro azione. Le pubblicazioni che coprono il periodo che va dal 15/11/2015 e il 07/03/2016 costituiranno il nostro corpus. All’intersezione tra scienze del linguaggio, studi nella comunicazione e sociologia, si tratterà di interrogare la maniera in cui alcuni procedimenti linguistici contribuiscono, con l’apporto semiologico delle immagini, a mettere in scena l’emozione e a suscitarla nel destinatario all’interno di un discorso relativamente omogeneo. L’ancoraggio contestuale contribuisce alla costruzione di una topica emozionale in quanto permette d’instaurare una modalità “patemica” della lettura dei post. L’obiettivo è di mostrare come il discorso dell’odio in rete costituisca un universo discorsivo con caratteristiche proprie, inscrivendosi in una tripla dimensione discorsiva, pre-discorsiva e post-discorsiva.

description: We present a comprehensive review of the physical behavior of yield stress materials in soft condensed matter, which encompass a broad range of materials from colloidal assemblies and gels to emulsions and non-Brownian suspensions. All these disordered materials display a nonlinear flow behavior in response to external mechanical forces, due to the existence of a finite force threshold for flow to occur: the yield stress. We discuss both the physical origin and rheological consequences associated with this nonlinear behavior, and give an overview of experimental techniques available to measure the yield stress. We discuss recent progress concerning a microscopic theoretical description of the flow dynamics of yield stress materials, emphasizing in particular the role played by relaxation time scales, the interplay between shear flow and aging behavior, the existence of inhomogeneous shear flows and shear bands, wall slip, and non-local effects in confined geometries.

description: We introduce various models for cellulose bio-degradation by micro-organisms. Those models rely on complex chemical mechanisms, involve the structure of the cellulose chains and are allowed to depend on the phenotypical traits of the population of micro-organisms. We then use the corresponding models in the context of multiple-trait populations. This leads to classical, logistic type, reproduction rates limiting the growth of large populations but also, and more surprisingly, limiting the growth of populations which are too small in a manner similar to the effects seen in populations requiring cooperative interactions (or sexual reproduction). This study hence offers a striking example of how some mechanisms resembling cooperation can occur in structured biological populations, even in the absence of any actual cooperation.

description: Using the latest observational data we obtain a lower bound on the initial value of the quintessence field in thawing quintessence models of dark energy. For potentials of the form V(ϕ) ϕ^{\pm2} we find that the initial value |ϕ_i|>7x10^{18}\gev. We then relate ϕ_i to the duration of inflation by assuming that the initial value of the quintessence field is determined by quantum fluctuations of the quintessence field during inflation. From the lower bound on $ϕ_i$ we obtain a lower bound on the number of e-foldings of inflation, namely, N>2x10^{11}. We obtain similar bounds for other power law potentials for which too we obtain |ϕ_{i}|>O(M_{P}.

In this paper, working in the context of string topology of classifying spaces, we provide explicit calculations of a wealth of non-trivial higher string topology operations associated to a number of different Lie groups. As an application of these calculations, we obtain an abundance of interesting homology classes in the twisted homology groups of automorphism groups of free groups, the ordinary homology groups of holomorphs of free groups, and the ordinary homology groups of affine groups over the integers and the field of two elements.

description: A partire da un corpus che ripercorre i momenti cruciali della nave umanitaria Aquarius durante la settimana che va dal 10 al 17 giugno 2018, ci proponiamo di osservare la maniera in cui il numerico, in particolare twittwr, ha permesso a Matteo Salvini, leader della Lega e all’epoca Ministro dell’Interno, di alimentare a colpi di clic una potente propaganda politica innestata sul passionale in rete. Trattando il tweet come una piccola sequenza discorsiva e adottando di conseguenza la metodologia dell’analisi del discorso applicata al numerico, ci soffermeremo sulla sua dinamica enunciativa per dimostrare come il tweet si configuri più come un luogo patemico che come un luogo argomentativo, e questo grazie alla sua forte carica timica che lo rende un sentimento diffuso – e « contagioso » - di appartenenza tra individui  che condividono gli stessi desideri, le stesse paure, uno stesso immaginario, ovvero una stessa costruzione delle immagini di sè e dell’Altro.

description: Contrary to common expectation, a left-sneutrinos can occasionally be the lightest supersymmet- ric particle. This has important implications in both collider and dark matter studies. We show that same-sign tri-lepton (SS3L) events at the Large Hadron Collider, with any lepton having opposite sign vetoed, distinguish such scenarios, up to gluino masses exceeding 2 TeV. The jets + M ET signal rate is somewhat suppressed in this case, thus enhancing the scope of leptonic signals.

title:  Les mèmes : circulation des émotions-aphorisations dans les médias d’infotainment

description: La campagna presidenziale francese del 2017 ha permesso di mettere in luce i numerosi incisi dell’emozione nel dibattito politico-mediatico, in particolare sotto forma di « meme » (immagini virali umoristiche su Internet). L’intensità emozionale passa attraverso la distorsione dell’espressione facciale di un uomo politico, ciò che Dominique Maingueneau chiama « un visage associé à une aphorisation ». I meme presentano così delle emozioni decontestualizzate e poi ricontestualizzate. Raggruppati sotto la denominazione « reaction memes », queste emozioni permettono agli utenti dei socialnetworks di commentare un articolo senza srivere la minima frase ; le sole frasi ammissibili in questo esercizio sono dei topoï già codificati. La circolazione di questi meme, tra reti sociali e discorsi mediatici, è forse il segno di un nuovo trattamento dell’emozione mediatica o si iscrive piuttosto nella categoria delle aforizzazioni descritte da Dominique Maingueneau? C’è una specificità di questa scrittura web lavorata dall’emozione, cristallizzata in un insieme di figure delimitate? In questo intervento tenteremo di dimostrare l’idea che lo sviluppo dei media di informazione sociale e virale così come le trasmissioni d’infotainment hanno favorito l’emergenza dell’emozione in quanto supporto mediatico a parte intera.

Unifying Two Views on Multiple Mean-Payoff Objectives in Markov Decision Processes

description: We consider Markov decision processes (MDPs) with multiple limit-average (or mean-payoff) objectives. There exist two different views: (i) the expectation semantics, where the goal is to optimize the expected mean-payoff objective, and (ii) the satisfaction semantics, where the goal is to maximize the probability of runs such that the mean-payoff value stays above a given vector. We consider optimization with respect to both objectives at once, thus unifying the existing semantics. Precisely, the goal is to optimize the expectation while ensuring the satisfaction constraint. Our problem captures the notion of optimization with respect to strategies that are risk-averse (i.e., ensure certain probabilistic guarantee). Our main results are as follows: First, we present algorithms for the decision problems which are always polynomial in the size of the MDP. We also show that an approximation of the Pareto-curve can be computed in time polynomial in the size of the MDP, and the approximation factor, but exponential in the number of dimensions. Second, we present a complete characterization of the strategy complexity (in terms of memory bounds and randomization) required to solve our problem.

description: Lunghi o brevi, destinati al pubblico di una mostra, di un museo, i testi espografici sono collocati accanto alle opere, agli oggetti esposti, quale che siano le tipologie della mostra, del museo (belle arti, fotografia, scienze, eco-musei…) come accompagnamento e mediazione, utilizzando numerosi e diversi supporti: pannelli, testi termo-incollati alle pareti, totem interattivi, ecc. Non fanno parte della segnaletica; la loro destinazione, il loro ruolo, la loro evoluzione portano a considerarli  un oggetto sociale. Da anni il concetto di piacere è al centro delle preoccupazioni degli organizzatori di mostre, così come delle attese dei visitatori. Con il supporto di numerosi esempi, nell’ambito della linguistica e dell’ analisi del discorso,  intendiamo analizzare le strutture dei testi espografici, le emozioni  poste in evidenza o suggerite in  ottica patemica, e altre strategie discorsive.

description: Questo articolo interroga da un punto di vista info-comunicazionale la nostalgia in alcune produzioni mediatiche che portano sul passato dei videogiochi. L’approccio alla nostalgia tiene conto dei lavori nelle Scienze Umane e Sociali e descrive gli aspetti positivi, creativi e consapevoli della nostalgia, senza limitarsi alla sua dimensione passeista. Si tratta di approfondire la comprensione dei legami tra nostalgia e « retrogaming » attraverso l’analisi del discorso e di osservarne la messa in scena in tre tipi di produzione mediatica : mostre museali sulla storia dei videogiochi, riedizione di giochi di console, video di amatori condivisi su piattaforme generaliste. A partire da una metodologia qualitativa, l’analisi si sofferma nello specifico sui supporti, sui procedimenti da cui dipendono queste espressioni nostalgiche e il ruolo strategico che giocano. L’articolo porta sulle sfide e sulle modalità della mediatizzazione del passato dei videogiochi nel presente dei media e dell’industria, trattando il videogioco come un oggetto patrimoniale. I risultati mettono l’accento sui legami tra le differenti temporalità del videogioco, sulla relazione tra nostalgia e autenticità attraverso l’onnipresenza dell’ambiente materiale del passato, e sul rinnovamento della figura del giocatore che valorizza l’esperienza del gioco.

description: Supersymmetry does not dictate the way we should quantize the fields in the supermultiplets, and so we have the freedom to quantize the Standard Model (SM) particles and their superpartners differently. We propose a generalized quantization scheme under which a particle can only appear off-shell, while its contributions to quantum corrections are exactly the same as those in the usual quantum field theory. We apply this quantization scheme solely to the sparticles in the $R$-parity preserving Minimal Supersymmetric Standard Model (MSSM). Thus sparticles can only appear off-shell. They could be light but would completely escape the direct detection at any experiments such as the LHC. However, our theory still retains the same desirable features of the usual MSSM at the quantum level. For instance, the gauge hierarchy problem is solved and the three MSSM gauge couplings are unified in the usual way. Although direct detection of sparticles is impossible, their existence can be revealed by precise measurements of some observables (such as the running QCD coupling) that may receive quantum corrections from them and have sizable deviations from the SM predictions. Also the experimental constraints from the indirect sparticle search are still applicable.

An inexact Krylov subspace method for response calculations in density functional theory
Creators: name: Sun, Bonan
Publisher: name: Zenodo
Year: 2024

description: Kohn-Sham density functional theory (DFT) is today the most popular electronic structure theory in quantum chemistry. In this framework, Density Functional Perturbation Theory (DFPT) is pivotal for computing various quantities that physically represent the response of the ground state density to external perturbations. The key building block of these response calculations is the computationally intensive task of solving the Dyson equation. It involves the iterative solution of a large linear system, wherein each iteration necessitates solving multiple smaller linear systems. In this thesis, we propose an inexact Krylov subspace method to dynamically adjust the tolerance of the inner iteration to accelerate the computation. We study the theoretical properties of the proposed method and show its effectiveness in numerical experiments. Our strategy can save up to 40% of the cost-dominating Hamiltonian applications without compromising the accuracy of the returned solution.
Wigner`s quantum phase-space current in weakly-anharmonic weakly-excited two-state systems

description: There are no phase-space trajectories for anharmonic quantum systems, but Wigner's phase-space representation of quantum mechanics features Wigner current~$\bf J$. This current reveals fine details of quantum dynamics -- finer than is ordinarily thought accessible according to quantum folklore invoking Heisenberg's uncertainty principle. Here, we focus on the simplest, most intuitive, and analytically accessible aspects of~$\bf J$. We investigate features of~$\bf J$ for bound states of time-reversible, weakly-anharmonic one-dimensional quantum-mechanical systems which are weakly-excited. We establish that weakly-anharmonic potentials can be grouped into three distinct classes: hard, soft, and odd potentials. We stress connections between each other and the harmonic case. We show that their Wigner current fieldline patterns can be characterised by~$\bf J$'s discrete stagnation points, how these arise and how a quantum system's dynamics is constrained by the stagnation points' topological charge conservation. We additionally show that quantum dynamics in phase space, in the case of vanishing Planck constant $\hbar$ or vanishing anharmonicity, does not pointwise converge to classical dynamics.

description: Rapid urbanization has an accelerated impact on catchment hydrology and geomorphology due to land use and land cover changes as a result of anthropogenic development activities in river catchment areas that causes increase surface runoff and higher sediment yield. The present study investigate the channel changes and sediment transport phenomena, including bed material movement from the upstream to the estuaries of the Pahang River Basin, Peninsula Malaysia. River geometry survey associated with the spatial variation in sediment transport has confirmed that changes in river bed profile occurres due to the erosion and sediment deposition along Pahang River. The sediment distribution size for the Pahang River was very coarse sand and gravel after December 2014 flood which subsequent. River geometry survey showed of gentle slope that can induce lower discharge typical of alluvial rivers relating to flood events. Quantitative assessment of sediment load is therefore of critical importance for future river basin management.
