Microscydmus

description: ? Microscydmus sp. 3
(Figs 31, 209–214)
Material studied. Late Eocene of Europe, Rovno amber: sex unknown; inclusion in elongate, subrectangular prism of amber 14 mm long (Fig. 31), collection number K-3657a (SIZK).
Description. Body (Figs 209–214) elongate, moderately slender and convex, light brown; BL 0.61 mm.
Head (Figs 209–214) short and subtrapezoidal, broadest at eyes, HL 0.10 mm, HW 0.15 mm; vertex (Fig. 212; vt) and frons (Fig. 212; fr) confluent, weakly convex and together subtrapezoidal, strongly transverse; eyes large, oval, strongly convex; tempora distinctly shorter than eyes. Punctures on frons and vertex (Fig. 212) fine but discernible, separated by spaces about twice as wide as diameters of punctures; setae poorly visible. Antennae (Figs 209–214) slightly shorter than half BL, AnL about 0.27 mm, scape and pedicel strongly elongate, antennomeres III–VI each about as long as broad, VII distinctly transverse, VIII weakly transverse, IX and X distinctly transverse, XI much shorter than IX–X combined, about 1.2 × as long as broad, distinctly narrower than X and rounded at apex.
Pronotum (Figs 209–210, 212–213) round, broadest near anterior fourth; PL 0.16 mm, PW 0.18 mm; anterior margin weakly emarginate; anterior pronotal corners weakly marked, broadly obtuse-angled and blunt; sides strongly rounded; posterior corners well-marked, obtuse-angled and blunt; posterior margin slightly angulate at middle; base with very short but distinct sublateral carinae (Fig. 212; slc) and two pairs of small antebasal pits (Fig. 212; abp). Punctures on pronotal disc (Fig. 212) similar to those on head; setae (Fig. 212) on disc poorly visible, on sides replaced by thick setae.

Keeping a spin qubit alive in natural silicon: Comparing optimal working points and dynamical decoupling

description: There are two distinct techniques of proven effectiveness for extending the coherence lifetime of spin qubits in environments of other spins. One is dynamical decoupling, whereby the qubit is subjected to a carefully timed sequence of control pulses; the other is tuning the qubit towards 'optimal working points' (OWPs), which are sweet-spots for reduced decoherence in magnetic fields. By means of quantum many-body calculations, we investigate the effects of dynamical decoupling pulse sequences far from and near OWPs for a central donor qubit subject to decoherence from a nuclear spin bath. Key to understanding the behavior is to analyse the degree of suppression of the usually dominant contribution from independent pairs of flip-flopping spins within the many-body quantum bath. We find that to simulate recently measured Hahn echo decays at OWPs (lowest-order dynamical decoupling), one must consider clusters of three interacting spins, since independent pairs do not even give finite $T_2$ decay times. We show that while operating near OWPs, dynamical decoupling sequences require hundreds of pulses for a single order of magnitude enhancement of $T_2$, in contrast to regimes far from OWPs, where only about ten pulses are required.

description: Schwinger pair creation in a purely time-dependent electric field can be described through a quantum Vlasov equation describing the time evolution of the single-particle momentum distribution function. This equation exists in two versions, both of which can be derived by a Bogoliubov transformation, but whose equivalence is not obvious. For the spinless case, we show here that the difference between these two evolution equations corresponds to the one between the "in-out" and "in-in" formalisms. We give a simple relation between the asymptotic distribution functions generated by the two Vlasov equations. As examples we discuss the Sauter and single-soliton field cases.

description: We show that Yukawa couplings of bottom quarks and tau leptons can be unified in a non-supersymmetric SU(5) model. We introduce an arbitrary number of right-handed neutrinos. Their masses and Yukawa couplings that satisfy the unification condition by renormalization group evolution are shown. In the case that the grand unification scale is $10^{15.5}$GeV and three right-handed neutrinos have the same mass, the upper bound on their mass is $\sim 10^{14.1}$GeV.

description: It has been demonstrated that halophytes had the potential to accumulate heavy metals and therefore had the remediation potential of soils affected by metals. In this context, Arthrocnemum indicum was supplied with increased doses of Aluminium (Al) (200, 500, 800 µM) alone or added to NaCl (200 mM). Results demonstrated that Al was found mainly in the cell wall in the shoots and the roots. The addition of the salt displaced the localization of Al in the roots, it was found bound to intercellular and proteiccomponents. These results suggest that the subcellular distribution of Al plays an important role in avoidance of metal toxicity.

Elucidating the molecular mechanisms of non-canonical type III IFN signaling
Creators: name: Bobrowski, Tesia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Interferons (IFNs) are cytokines that function in the innate immune response to viral infection. Type I and type III IFNs canonically signal through the Janus kinase–signal transducer and activator of transcription (JAK-STAT) pathway, although non-canonical signaling pathways have been described. It is unclear how the differences between these canonical and non-canonical signaling pathways and their roles in type I vs. type III IFN signaling influence infection outcomes. Notably, our group has shown that type III IFN signaling at the maternal-fetal interface is associated with adverse fetal outcomes during Zika virus infection in mice. To study the differences between the type I and type III IFN signaling pathways, we constructed monoclonal knockout (KO) cell lines for the type I and type III IFN receptors (IFNAR1 and IFNLR1), as well as a key component of the JAK-STAT pathway (STAT2) in a lung epithelial cell line (A549). Monoclonal KO cell populations were genotypically validated via Sanger sequencing and phenotypically validated by assays assessing ISG induction and viral inhibition. RNA-Seq was performed on IFNAR1 and IFNLR1 KO A549 cells, revealing possible gene targets that are uniquely regulated by expression of the IFNLR1 receptor. Our STAT2 KO cell model generated herein provides a valuable system to interrogate pathways induced via non-canonical mechanisms. Combined with the results of our existing RNA-Seq analysis, we can examine which genes may be preferentially induced by type III IFN signaling and via non-canonical molecular mechanisms.

Sea Turtles Respond to Waterborne Odors of Biofouled Plastic
Creators: name: Rönn, Alva
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Millions of tons of plastic waste and debris fill Earth’s oceans and greatly impact marine flora and fauna, causing entanglement, smothering, or ingestion. Sea turtles are known to ingest large amounts of this plastic debris. A possible cause for plastic ingestion is that plastic in the ocean becomes biofouled, or colonized by various microorganisms, giving the plastic the appearance or odor of food. Loggerhead sea turtles (Caretta caretta) have been found to be attracted to airborne biofouled plastic odors, however, sea turtles spend the majority of their lives underwater and forage almost exclusively underwater. Yet, the role of waterborne biofouled plastic odors remains unknown. To address this question, we investigated the response of sea turtles to waterborne biofouled plastic odors as compared to their responses to waterborne odors of food, clean plastic, and artificial seawater. Turtles showed increased biting of the food and biofouled plastic odor sources compared to the clean plastic and artificial sea water odors. This response suggests a similar attraction to biofouled plastic and food, providing a possible basis for why sea turtles so frequently ingest plastic. These results could also contribute to the development of protective interventions for marine life as plastic pollution continues to increase.

description: We use the Mopra radio telescope to test for expansion of the molecular gas associated with the bubble HII region RCW120. A ring, or bubble, morphology is common for Galactic HII regions, but the three-dimensional geometry of such objects is still unclear. Detected near- and far-side expansion of the associated molecular material would be consistent with a three-dimensional spherical object. We map the $J = 1\rightarrow 0$ transitions of $^{12}$CO, $^{13}$CO, C$^{18}$O, and C$^{17}$O, and detect emission from all isotopologues. We do not detect the $0_0\rightarrow 1_{-1} E$ masing lines of CH$_3$OH at 108.8939 GHz. The strongest CO emission is from the photodissociation region (PDR), and there is a deficit of emission toward the bubble interior. We find no evidence for expansion of the molecular material associated with RCW120 and therefore can make no claims about its geometry. The lack of detected expansion is roughly in agreement with models for the time-evolution of an HII region like RCW120, and is consistent with an expansion speed of $< 1.5\, {\rm km\, s^{-1}}$. Single-position CO spectra show signatures of expansion, which underscores the importance of mapped spectra for such work. Dust temperature enhancements outside the PDR of RCW120 coincide with a deficit of emission in CO, confirming that these temperature enhancements are due to holes in the RCW120 PDR. H$α$ emission shows that RCW120 is leaking $\sim5\%$ of the ionizing photons into the interstellar medium (ISM) through PDR holes at the locations of the temperature enhancements. H-alpha emission also shows a diffuse "halo" from leaked photons not associated with discrete holes in the PDR. Overall $25\pm10\%$ of all ionizing photons are leaking into the nearby ISM.

Testing an Extension of the I3 Theory to Teen Dating Violence Perpetration: A Latent Profile Analysis

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Teen dating violence (TDV) is the perpetration of harmful physical or non-physical violence against a dating partner in an adolescent dating relationship. This study tests an extension of the I3 theory (Finkel, 2007) of intimate partner violence, to TDV perpetration. This study uses latent profile analysis to examine patterns in its sample’s levels of factors included in the I3 theory: anger, depressive symptoms, impulsivity, and alcohol use. This study analyzed the longitudinal relationship between profile membership and frequency of TDV perpetration of different types. None of the profiles were associated with frequent TDV perpetration at baseline or one year later. However, the profile with a high mean of recent alcohol use was the profile associated with the most frequent perpetration of most types across time. The results were both in support and in contrast to the extension of the I3 theory to TDV perpetration and therefore, warrant future study.

description: We discuss minisuperspace models within the framework of varying physical constants theories including $Λ$-term. In particular, we consider the varying speed of light (VSL) theory and varying gravitational constant theory (VG) using the specific ansätze for the variability of constants: $c(a) = c_0 a^n$ and $G(a)=G_0 a^q$. We find that most of the varying $c$ and $G$ minisuperspace potentials are of the tunneling type which allows to use WKB approximation of quantum mechanics. Using this method we show that the probability of tunneling of the universe "from nothing" ($a=0)$ to a Friedmann geometry with the scale factor $a_t$ is large for growing $c$ models and is strongly suppressed for diminishing $c$ models. As for $G$ varying, the probability of tunneling is large for $G$ diminishing, while it is small for $G$ increasing. In general, both varying $c$ and $G$ change the probability of tunneling in comparison to the standard matter content (cosmological term, dust, radiation) universe models.

Biogeography and macroecology of Australian marine molluscs

Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Latitudinal diversity gradients are the highest-order biodiversity patterns on Earth. Despite a large body of research into them, there is no consensus on their drivers. Furthermore, studies of latitudinal gradients tend to either ignore or simplify biogeographic structure in their analyses, despite the usefulness of biogeographic schemes in regional conservation planning. As such, there is a disconnect in our understanding of patterns of diversity and faunal composition. In this thesis I reach for a new synthesis, simultaneously establishing both biogeographic and macroecological patterns for a highly diverse group, marine molluscs, with a focus on the coastline of Australia. In the first chapter of this thesis, I give a brief account of how previous research has analysed the latitudinal diversity gradient. I also discuss various global and regional bioregionalisations and their varied methodological approaches. In the second chapter, I use factor analysis to produce a global biogeographic scheme for molluscs that improves on previous research by quantifying gradients between provinces. I then use these province definitions to examine the drivers of their boundaries, showing that as coral reefs become more common in an area its composition changes systematically. The third chapter then applies the same methods to a study of the coastline of Australia, producing a regional scheme that complements previous work. I use it to investigate spatial patterns of diversity around the continent, relating the observed changes in biogeographic structure to diversity patterns. I show that commonly flagged environmental correlates are only indirectly tied to diversity via their control of biogeographic transitions. In the following chapters I utilise a large field collection drawn from across the eastern coastline to quantify diversity. In the fourth chapter I compare the biogeographic and diversity patterns present in the field collection to those generated from routine macroecological datasets stemming from online databases. I find that latitudinal gradients are stronger in the field data, but there is much variance depending on the choice of diversity estimator and the inclusion or exclusion of observational data. In chapter five I show that despite large sample sizes and a rigorous study design, there is no latitudinal signal in body size distributions or abundance data in the field data, contrary to previous work. The approaches taken in this thesis highlight how several generalisations about latitudinal diversity gradients do not apply to Australia. Instead, new methods applied to generating biogeographic schemes may help to explain the drivers of observed patterns. Additionally, these methods demonstrate how to retain more information in bioregionalisation schemes, potentially aiding future assessments of optimal marine reserve placement.

description: Defining the extent of epistasis - the non-independence of the effects of mutations - is essential for understanding the relationship of genotype, phenotype, and fitness in biological systems. The applications cover many areas of biological research, including biochemistry, genomics, protein and systems engineering, medicine, and evolutionary biology. However, the quantitative definitions of epistasis vary among fields, and its analysis beyond just pairwise effects remains obscure in general. Here, we show that different definitions of epistasis are versions of a single mathematical formalism - the weighted Walsh-Hadamard transform. We discuss that one of the definitions, the backgound-averaged epistasis, is the most informative when the goal is to uncover the general epistatic structure of a biological system, a description that can be rather different from the local epistatic structure of specific model systems. Key issues are the choice of effective ensembles for averaging and to practically contend with the vast combinatorial complexity of mutations. In this regard, we discuss possible approaches for optimally learning the epistatic structure of biological systems.

description: Context: Several binary systems hosting massive stars present gamma-ray emission. In most of these systems, despite detailed observational information being available, the nature and the structure of the emitter are still poorly known. Aims: We investigate the validity of the so-called one-zone approximation for the high-energy emitter in binary systems hosting a massive star. In particular, the case of LS 5039 is considered. Methods: Assuming a point-like emitter at rest, the presence of a nearby massive star, and the observed MeV and GeV fluxes as a reference, a non-thermal leptonic model is systematically applied for different locations, magnetic fields, and non-radiative losses. This allows us to identify both the emitter configurations that are most compatible with observations and inconsistencies between model predictions and the available data. Results: In the case of LS 5039, the best parameter combination is fast non-radiative cooling and a low magnetic field. However, discrepancies appear when comparing the model results at the MeV and GeV energy ranges with the observed fluxes. Predictions fail when the orbital motion is included in the analysis, because emitters and energy budgets that are too large are required. Values of X-ray and TeV fluxes that are too high are predicted in such a case, along half of the orbit. Conclusions: We show that the radiation in LS 5039 does not come from only one electron population, and the emitter is likely extended and inhomogeneous with a low magnetic field. We suggest that the emitter moves at relativistic velocities with Doppler boosting playing a significant role. Key words. Stars: high-mass, X-rays: binaries, gamma-rays: binaries

In this paper we give a new proof to a theorem of Bertolini which determines the value of the $Λ$-corank of $\text{Sel}(E/K_{\infty})$ in the case where $E$ has ordinary reduction at $p$. In the case where $E$ has supersingular reduction at $p$ we make a conjecture about the structure of the module of Heegner points mod $p$. Assuming this conjecture we give a new proof to a theorem of Ciperiani which determines the value of the $Λ$-corank of $\text{Sel}(E/K_{\infty})$ in the case where $E$ has supersingular reduction at $p$.

The non-conservation of the energy-momentum tensor, predicted by f(R,T) theory, allows the derivation of a relation that describes the time evolution of the extra coordinate, revealing its compactification. It is showed that such a compactification could induce the effects of an accelerated expansion in the observable universe.

Exploring the Role of CUL9 in Cortical Structure and Neuronal Morphology
Creators: name: Oberhauser, Jane
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Cullin-9 (CUL9) is a member of the Cullin ubiquitin ligase family strongly expressed in the brain. Recently, the Deshmukh Lab has identified behavioral deficits including anxiety, hyperactivity, and social defects in Cul9 knockout mice. The association of Cul9 genetic variants with schizophrenia suggests that CUL9 plays an important role in the brain. However, CUL9’s specific function remains virtually unknown. This study sought to explore the physiological role of CUL9 in the brain by investigating the impact of Cul9 loss on cortical and neuronal morphology. Confocal images of brain sections from wild type and Cul9 knockout mice were stained for various cortical markers and analyzed for differences in cortical layer size. Results showed lateral ventricle enlargement in Cul9 knockout consistent with abnormalities identified in schizophrenia patients. To examine the morphology of cortical projection neurons in vivo, wild type and Cul9 knockout mice were crossed with Thy1-YFP mice and three-dimensional confocal images of these neurons were reconstructed and quantified. Interestingly, cortical excitatory neurons from Cul9 knockout brains displayed decreased dendritic complexity compared to their wild type counterparts. These results suggest that CUL9 influences neuronal arborization. Interestingly, this trend parallels the results of previous studies associating reduced dendritic complexity with schizophrenia and opens avenues to further understanding how CUL9 may affect normal brain function.

Description. Body (Figs 215–216) elongate, moderately slender and convex, dark brown; BL 0.98 mm.
Head (Figs 215–216) broadest at eyes, HL 0.15 mm; vertex and frons not visible; eyes large, oval, strongly convex; tempora seem shorter than eyes. Punctures and setae on frons and vertex poorly visible. Antennae (Figs 215–216) much shorter than half BL, AnL about 0.34 mm, gradually thickened distally and relatively slender, scape and pedicel strongly elongate, shapes of remaining antennomeres difficult to define.
Pronotum (Figs 215–216) elongate, broadest at base but with nearly parallel-sided lateral margins in posterior half; PL 0.28 mm, PW 0.23 mm; anterior margin strongly and evenly rounded and laterally confluent with lateral margins, so that anterior pronotal corners are not marked; sides rounded in anterior third and nearly straight in posterior half; posterior corners distinct, nearly right-angled, blunt; posterior margin nearly straight; base with one pair of shallow and diffused lateral pits (Fig. 216; abp) connected by complete and uninterrupted transverse antebasal groove (Fig. 216; abg). Punctures on pronotal disc (Fig. 216) small but distinct, separated by spaces 2–3 × as wide as diameters of punctures; setae (Fig. 216) sparse, short and suberect.
Elytra (Figs 215–216) elongate oval, moderately convex, broadest near middle, EL 0.55 mm, EW 0.35 mm, EI 1.57; elytral base distinctly broader than base of pronotum; each elytron with one distinct asetose basal fovea (Fig. 216; bef); punctures and setae (Fig. 216) similar to those on pronotal disc.
Legs (Figs 215–216) moderately long, slender, unmodified.
Remarks. Diagnostic characters of the extant genus Scydmoraphes Reitter, 1891 were illustrated and summarized in Jałoszyński (2015f). Characters of the Rovno amber specimen K-6764 that suggest it can belong in Scydmoraphes are as follows: the pronotum elongate, with rounded anterior margin, anterior pronotal corners not marked, posterior pronotal corners distinct; lateral pronotal margins developed as sharp edges or carinae (Fig. 216; lpc), the pronotal base with one pair of lateral pits (Fig. 216; abp) developed as shallow and diffused impressions connected by complete transverse antebasal groove (Fig. 216; abg); and each elytron with one distinct and asetose basal fovea (Fig. 216; bef). However, the most important ventral characters are not visible and the placement in genus is putative.

description: We study ferromagnetism at high density of neutrons in the QCD hadron phase, by using the simplest chiral effective model incorporating magnetic fields and the chiral anomaly. Under the assumption of spatial homogeneity, we calculate the energy density as a function of neutron density, with a magnetization and a neutral pion condensation a la Dautry and Neyman. We find that at a high density the energy of the ferromagnetic order is lower than that of the ordinary neutron matter, and the reduction effect is enhanced by the anomaly. Compared to the inhomogeneous phase with the alternating layer structure, our ferromagnetic phase turns out to be unfavored. However, once an axial vector meson condensation is taken into account in our simplest model, the ferromagnetic energy density is lowered significantly, which still leaves some room for a possible realization of a QCD ferromagnetic phase and ferromagnetic magnetars.

description: We present a novel approach for the optical manipulation of neutral atoms in annular light structures produced by the phenomenon of conical refraction occurring in biaxial optical crystals. For a beam focused to a plane behind the crystal, the focal plane exhibits two concentric bright rings enclosing a ring of null intensity called the Poggendorff ring. We demonstrate both theoretically and experimentally that the Poggendorff dark ring of conical refraction is confined in three dimensions by regions of higher intensity. We derive the positions of the confining intensity maxima and minima and discuss the application of the Poggendorff ring for trapping ultra-cold atoms using the repulsive dipole force of blue-detuned light. We give analytical expressions for the trapping frequencies and potential depths along both the radial and the axial directions. Finally, we present realistic numerical simulations of the dynamics of a $^{87}$Rb Bose-Einstein condensate trapped inside the Poggendorff ring which are in good agreement with corresponding experimental results.

description: Η παρούσα εργασία διερευνά τη διασταύρωση της διαχείρισης ανθρώπινου δυναμικού (HR) και των μέσων κοινωνικής δικτύωσης (social media) από την οπτική γωνία των εταιρικών και ναυτιλιακών βιομηχανιών. Αρχικά, αναλύεται η σημασία των μέσων κοινωνικής δικτύωσης στις εταιρικές πρακτικές HR, παρουσιάζοντας πώς οι παραδοσιακές μέθοδοι εξελίσσονται με την ενσωμάτωση των social media. Εξετάζεται ο αντίκτυπος τους στις στρατηγικές HR, όπως η πρόσληψη προσωπικού, η δέσμευση των εργαζομένων, η επωνυμία του εργοδότη και η διαχείριση ταλέντων. Στη συνέχεια, το ενδιαφέρον μετατοπίζεται στη ναυτιλιακή βιομηχανία, όπου η εργασία διερευνά την εξέλιξη των τεχνικών HR στον τομέα αυτό. Παρουσιάζονται ιστορικά ορόσημα και πιθανές μελλοντικές εξελίξεις, με έμφαση στην αυξανόμενη σημασία των μέσων κοινωνικής δικτύωσης στη διαχείριση ανθρώπινων πόρων. Αναλύεται ο τρόπος με τον οποίο τα social media ενσωματώνονται στις διαδικασίες HR και επηρεάζουν την πρόσληψη, τη δέσμευση των εργαζομένων, την επωνυμία του εργοδότη και τη διαχείριση ταλέντων στις ναυτιλιακές επιχειρήσεις. Η εργασία επίσης καταδύεται στις προκλήσεις της εφαρμογής των social media στις ναυτιλιακές επιχειρήσεις, όπως οι ανησυχίες για το απόρρητο και την ασφάλεια δεδομένων, η κατανόηση του τοπίου των μέσων κοινωνικής δικτύωσης και η εναρμόνιση των πολιτικών HR με τους διεθνείς κανονισμούς. Εξετάζονται οι βέλτιστες πρακτικές για τη δέσμευση στα social media, η εκπαίδευση του προσωπικού HR σε θέματα επάρκειας των μέσων κοινωνικής δικτύωσης και η αξιοποίηση αναλυτικών εργαλείων για τη λήψη αποφάσεων βάσει δεδομένων. Η εργασία επιδιώκει να παράσχει μια ολοκληρωμένη αξιολόγηση του τρόπου με τον οποίο οι πρακτικές HR επηρεάζονται από τα μέσα κοινωνικής δικτύωσης τόσο σε εταιρικό όσο και σε ναυτιλιακό πλαίσιο, και να εξετάσει τις προκλήσεις και τις ευκαιρίες που παρουσιάζονται.

Effects of Alternative Splicing of Capping Actin Protein (CAPZB) on Skeletal Muscle Cell Proliferation and Differentiation
Creators: name: Essader, Tasneem
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: The capping actin protein of muscle z-line subunit beta (CAPZB) is involved in the assembly and function of actin filaments in skeletal muscle cells. Exon of 113 nucleotides (nt) of CAPZB gene is regulated by alternative splicing. and the two protein isoforms are localized in different places within cardiac muscle cells. However, little is known about the localization or functions of the two isoforms in skeletal muscle cells. The first aim of this thesis was to better understand the functions of the two CAPZB splice isoforms in skeletal muscle cells. To address this question, we used morpholino antisense oligonucleotides to force the expression of the variant lacking the exon in C2C12 mouse myoblast cells and determine the impact of the two isoforms on cell proliferation and differentiation. The second goal of this thesis was to develop ImageJ macros for the automatic quantification of myotube area, total number of nuclei, and myotube fusion using microscopy images from immunofluorescence experiments. First, we found that both CAPZB splice isoforms behave similarly when evaluating muscle cell proliferation and differentiation. Second, when we compared the values achieved from the macros developed here with manual quantification done by researchers, we observed a high degree of correlation between the two methods of quantification. Therefore, the macros successfully developed in this thesis provided accurate biological values.

description: The electrostatic potential in the neighborhood of a biomolecule can be computed thanks to the non-linear divergence-form elliptic Poisson-Boltzmann PDE. Dedicated Monte-Carlo methods have been developed to solve its linearized version (see e.g.Bossy et al 2009, Mascagni & Simonov 2004}). These algorithms combine walk on spheres techniques and appropriate replacements at the boundary of the molecule. In the first part of this article we compare recent replacement methods for this linearized equation on real size biomolecules, that also require efficient computational geometry algorithms. We compare our results with the deterministic solver APBS. In the second part, we prove a new probabilistic interpretation of the nonlinear Poisson-Boltzmann PDE. A Monte Carlo algorithm is also derived and tested on a simple test case.
