description: This paper aims to validate the $β$-Ginibre point process as a model for the distribution of base station locations in a cellular network. The $β$-Ginibre is a repulsive point process in which repulsion is controlled by the $β$ parameter. When $β$ tends to zero, the point process converges in law towards a Poisson point process. If $β$ equals to one it becomes a Ginibre point process. Simulations on real data collected in Paris (France) show that base station locations can be fitted with a $β$-Ginibre point process. Moreover we prove that their superposition tends to a Poisson point process as it can be seen from real data. Qualitative interpretations on deployment strategies are derived from the model fitting of the raw data.

description: Between December 2020 and April 2023, the COVID-19 Scenario Modeling Hub (SMH) generated operational multi-month projections of COVID-19 burden in the US to guide pandemic planning and decision-making in the context of high uncertainty. This effort was born out of an attempt to coordinate, synthesize and effectively use the unprecedented amount of predictive modeling that emerged throughout the COVID-19 pandemic. Here we describe the history of this massive collective research effort, the process of convening and maintaining an open modeling hub active over multiple years, and attempt to provide a blueprint for future efforts. We detail the process of generating 17 rounds of scenarios and projections at different stages of the COVID-19 pandemic, and disseminating results to the public health community and lay public. We also highlight how SMH was expanded to generate influenza projections during the 2022–23 season. We identify key impacts of SMH results on public health and draw lessons to improve future collaborative modeling efforts, research on scenario projections, and the interface between models and policy.

Notes on the systematic position of the Stenheliinae (Copepoda, Harpacticoida)within the Thalestridimorpha and description of two new species from Motupore Island, Papua New Guinea
Creators: name: WILLEN, Elke
Publisher: name: Station Biologique de Roscoff (SBR)
Year: 2002

description: Two new species of Stenheliinae, Stenhelia (D.) schminkei sp. nov. and Melima papuaensis sp. nov. are described
 from intertidal mud and algal washings from Motupore Island, Papua New Guinea. S. schminkei can be assigned to a species
 group also containing S. clavus, S. paraclavus and S. valens all described from the Andaman Islands. They share an
 apomorphic setation pattern of the swimming legs, a confluent female P5 and the special shape of the male P5. The group
 seems to have only a restricted distribution within the Indo-Pacific region. In describing Melima papuaensis sp. nov. the
 genus Melima is reinstated as a first step towards a revision of the paraphyletic genus Stenhelia. Autapomorphies for this
 taxon are defined. A key to the females of Melima is provided. In the course of a phylogenetic analysis of the
 Thalestridimorpha it turned out, that the "Stenhelia-group" within the traditional Diosaccidae forms a monophylum which
 can be assigned together with the remaining species of the Diosaccidae and the species of the former family Miraciidae to a
 common taxon Miraciidae within the Thalestridimorpha. A historical overview and a summary of the discussion is given and
 an attempt is made to identify some monophyletic subtaxa within the Stenheliinae.
Evidence for an intramembrane component associated with a cellulose microfibril-synthesizing complex in higher plants
Creators: name: Mueller, Susette C.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1980

description: Freeze-fracture of rapidly frozen, untreated plant cells reveals terminal complexes on E-fracture faces and intramembrane particle rosettes on P-fracture faces. Terminal complexes and rosettes are associated with the ends of individual microfibril impressions on the plasma membrane. In addition, terminal complexes and rosettes are associated with the impressions of new orientations of microfibrils. These structures are sparse within pit fields where few microfibril impressions are observed, but are abundant over adjacent impressions of microfibrils. It is proposed that intramembrane rosettes function in association with terminal complexes to synthesize microfibrils. The presence of a cellulosic microfibril system in Zea mays root segments is confirmed by degradation experiments with Trichoderma cellulase.

description: Due to their modular design from inorganic building units (IBUs) and organic linker molecules, metal-organic frameworks (MOFs) exhibit great flexibility and variability in terms of their inherent properties. However, the creation of MOF-based electronic and optoelectronic devices, suitable for real-world applications, critically depends on the availability of highly adaptable materials, that can be patterned down to the nanometer scale. MOFs based on the linker benzophenone dicarboxylate (bzpdc) present a promising platform in this regard: They allow for the photochemical integration of almost any functionality into their frameworks through easily accessible postsynthetic modifications (PSMs). While this approach has been limited to powdered bulk materials so far, transitioning to more processable forms such as membranes or thin films is now crucial for their integration into practical applications. Light, the key initiator of the reaction, can be manipulated in various ways to create spatially resolved selective structures within bzpdc-MOFs. The PhD thesis presented here, addresses this issue and can be thematically divided into two main areas. The first section covers the shaping of a zirconium-based bzpdc-MOF for applications extending to 3D micropatterning. The second section of the PhD thesis is dedicated to the development of a novel, multifunctional bzpdc-MOF.
Disappearance of Comet C/2010 X1 (Elenin): Gone with a Whimper, not a Bang

description: We examine the rise and sudden demise of comet C/2010 X1 (Elenin) on its approach to perihelion. Discovered inbound at 4.2 AU, this long-period comet was predicted to become very bright when near perihelion, at 0.48 AU on 2011 September 10. Observations starting 2011 February (heliocentric distance $\sim$3.5 AU) indeed show the comet to brighten by about 11 magnitudes, with most of the increase occurring inside 1 AU from the Sun. The peak brightness reached $m_R$ = 6 on UT 2011 August 12.95$\pm$0.50, when at $\sim$0.83 AU from the Sun. We find that most of the surge in brightness in mid-August resulted from dust particle forward-scattering, not from a sudden increase in the activity. A much smaller ($\sim$3 magnitudes) brightening reached a maximum on UT 2011 August 30$\pm$1 (at 0.56 AU), and reflects the true break-up of the nucleus. This second peak was matched by a change in the morphology from centrally condensed to diffuse. The estimated cross-section of the nucleus when at 1 AU inbound was $\sim$1 km$^2$, corresponding to an equal-area circle of radius 0.6 km. No surviving fragments were found to a limiting red magnitude $r'$ = 24.4, corresponding to radii $\lesssim$40 m (red geometric albedo = 0.04 assumed). Our observations are consistent with disintegration of the nucleus into a power law size distribution of fragments with index $q$ = 3.3$\pm$0.2 combined with the action of radiation pressure. We speculate about physical processes that might cause nucleus disruption in a comet when still 0.7 AU from the Sun. Tidal stresses and devolatilization of the nucleus by sublimation are both negligible at this distance. However, the torque caused by mass loss, even at the very low rates measured in comet Elenin, is potentially large enough to be responsible by driving the nucleus to rotational instability.

description: This study documents the vertical and horizontal distribution of the heteropod Mollusks in the neritic epipelagic layer of the southern Gulf of Mexico. Plankton samples were taken at 28 sampling stations below the 18°N parallel in the southernmost Gulf of Mexico, during May and November 1995. Five vertical strata (0-6, 6-12, 12-18, 45-55 and 95-105 m) were sampled with an opening-closing net system equipped with 75-cm diameter and 505-µm mesh size nets, and a total of 187 samples were collected. Fourteen species of heteropod Mollusks were identified, and the dominant species, accounting for the 97% of the total abundance, were Atlanta lesueurii (60%), A. gaudichaudi (15%), Firoloida desmarestia (12%) and A. selvagensis (10%). In the vertical plane, their highest densities were recorded in the 0-18 m upper layer. Seasonally, only A. gaudichaudi registered its highest abundance in November. We hypothesize that shifts in seasonal dominance of heteropod species is an ecological strategy to avoid competition for feeding resources. The carinariid Carinaria challengeri was registered for the first time in the western Atlantic. A detailed documentation of the worldwide distribution of the 14 heteropod species is included.

description: Lifetimes of the states in the quadrupole structure in 143Eu have been measured using the Doppler shift attenuation method as well as parity of the states in the sequence has been firmly identified from polarization measurement using the Indian National Gamma Array. The decreasing trends of the deduced quadrupole transition strength B(E2) with spin, along with increasing J (2) /B(E2) values before band crossing, conclusively establish the origin of these states as arising out of antimagnetic rotation. The abrupt increase in the B(E2) values after the band crossing in the quadrupole band, a novel feature observed in the present experiment, may indicates the crossing of different shears configurations resulting in re-opening of shears structure. The results are well reproduced by numerical calculation within the framework of semi-classical geometric model.

description: Collective sensing by interacting cells is observed in a variety of biological systems, and yet a quantitative understanding of how sensory information is collectively encoded is lacking. Here we investigate the ATP-induced calcium dynamics of monolayers of fibroblast cells that communicate via gap junctions. Combining experiments and stochastic modeling, we find that increasing the ATP stimulus increases the propensity for calcium oscillations despite large cell-to-cell variability. The model further predicts that the oscillation propensity increases not only with the stimulus, but also with the cell density due to increased communication. Experiments confirm this prediction, showing that cell density modulates the collective sensory response. We further implicate cell-cell communication by coculturing the fibroblasts with cancer cells, which we show act as "defects" in the communication network, thereby reducing the oscillation propensity. These results suggest that multicellular networks sit at a point in parameter space where cell-cell communication has a significant effect on the sensory response, allowing cells to simultaneously respond to a sensory input and to the presence of neighbors.

description: We study the temporal evolution of a coherent state under the action of a parametric oscillator and a nonlinear Kerr-like medium. We make use of the interaction picture representation and use an exact time evolution operator for the time independent part of the Hamiltonian. We approximate the interaction picture Hamiltonian in such a way as to make it a member of a Lie algebra. The corresponding time evolution operator behaves like a squeezing operator due to the temporal dependence of the oscillator's frequency. We analyze the probability amplitude and the auto correlation function for different Hamiltonian parameters and we find a very good agreement between our approximate results and converged numerical calculations.

description: Cyclic nucleotides and cyclic nucleotide-dependent protein kinases have been implicated in the regulation of cell motility and division, processes that depend on the cell cytoskeleton. To determine whether cyclic nucleotides or their kinases are physically associated with the cytoskeleton during cell division, fluorescently labeled antibodies directed against cyclic AMP, cyclic GMP, and the cyclic nucleotide- dpendent protein kinases were used to localize these molecules in mitotic PtK1 cells. Both the cyclic GMP-dependent protein kinase and the type II regulatory subunit of the cyclic AMP-dependent protein kinase were localized on the mitotic spindle. Throughout mitosis, their distribution closely resembled that of tubulin. Antibodies to cyclic AMP, cyclic GMP, and the type I regulatory and catalytic subunits of the cyclic AMP-dependent protein kinase did not label the mitotic apparatus. The association between specific components of the cyclic neucleotide system and the mitotic spindle suggests that cyclic nucleotide-dependent phosphorylation of spindle proteins, such as those of microtubules, may play a fundamental role in the regulation of spindle assembly and chromosome motion.

Adiabaticity in open quantum systems

description: We provide a rigorous generalization of the quantum adiabatic theorem for open systems described by a Markovian master equation with time-dependent Liouvillian $\mathcal{L}(t)$. We focus on the finite system case relevant for adiabatic quantum computing and quantum annealing. Adiabaticity is defined in terms of closeness to the instantaneous steady state. While the general result is conceptually similar to the closed system case, there are important differences. Namely, a system initialized in the zero-eigenvalue eigenspace of $\mathcal{L}(t)$ will remain in this eigenspace with a deviation that is inversely proportional to the total evolution time $T$. In the case of a finite number of level crossings the scaling becomes $T^{-η}$ with an exponent $η$ that we relate to the rate of the gap closing. For master equations that describe relaxation to thermal equilibrium, we show that the evolution time $T$ should be long compared to the corresponding minimum inverse gap squared of $\mathcal{L}(t)$. Our results are illustrated with several examples.

title: Gender, Ethnicity and Power: Identity Formation in Two Italian Organisations of London
Creators: name: Fortier, Anne-Marie
Publisher: name: Goldsmiths, University of London
Year: 1996

description: This thesis is the study of two Italian organisations in London and their role in constructing an Italian 'community', at a time when the Italian population is fragmented and dispersed. In order to understand the languages of solidarity expressed in the two research settings, I use the concept of 'identity formation' and show that institutional practices of identity combine competing definitions to project meaning onto the indeterminate character of the Italian population of London. The essence of my argument is that within these settings, new forms of identity are developing which defy simple notions of 'community' and continuity based on a primary ethnicity. Similarly, models of radical pluralism are inadequate to grasp the complex articulation of roots and routes in the formation of group identities for immigrant populations. Languages of solidarity, in the two organisations, are generated by a group of claims about the historical, political and cultural presence of Italians in Britain. Multiple meanings group around the central symbol of (e) migration, representing a combination of essentialist and pluralist tendencies. Foundational ideas of national culture intersect with a diasporic consciousness of multi-local ties, trans-national networks and displacement, generating new geographies of identity that break open the seams of national boundaries. London Italian subjectivity is highly localised in relation to the family. Though emphatically patriarchal, the Italian emigrant family is represented as decidedly post-national: it constitutes a stage for the rehearsal of ethnicity, at a time when the nation is no longer the site and frame of memory. The relationship between family and cultural continuity is mediated through generations, while authenticity is configured around gender. Definitions of local particularity are drawn from deeply held ideas about gender differences and sexual behaviours, which provide some form of ontological security that fixes the relationship between family, ethnicity and community.
Cytoplasmic surface structure in postsynaptic membranes from electric tissue visualized by tannic-acid-mediated negative contrasting
Creators: name: Sealock, R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1982

description: In this study, acetylcholine receptor-rich postsynaptic membranes from electric tissues of the electric rays Narcine brasiliensis and Torpedo californica are negatively contrasted for thin-section electron microscopy through the use of tannic acid. Both outer (extracellular) and inner (cytoplasmic) membrane surfaces are negatively contrasted, and can be studied together in transverse sections. The hydrophobic portion of the membrane appears as a thin (approximately 2 nm), strongly contrasted band. This band is the only image given by membrane regions which are devoid of acetylcholine receptor. In regions of high receptor density, however, both surfaces of the membrane are seen to bear or be associated with material which extends approximately 6.5 nm beyond the center of the bilayer. The material on the outer surface can be identified with the well-known extracellular portion of the receptor molecule. A major portion of the inner surface image is eliminated by extraction of the membranes at pH 11 to remove peripheral membrane proteins, principally the 43,000 Mr (43K) protein. The images thus suggest a cytoplasmic localization of the 43K protein, with its distribution being coextensive with that of the receptor. They also suggest that the 43K protein extends farther from the cytoplasmic surface than does the receptor.

description: This ultrastructural study of the oocyte of Tethya aurantium adds new data to the knowledge of the germinal cells
 in the sponges of this genus. The ooplasm contains lipid droplets, electron-dense globules, phagosomes and rod-like
 inclusions. The most interesting feature of the oocytes is the high number of bacteria which are present in phagocytotic
 vacuoles in the oocyte cytoplasm and which derive from the mesohyl. While in other sponges the vacuoles usually contain
 a single bacterium, in T. aurantium the vacuoles are large and contain groups of bacteria. The bacteria engulfed by the
 oocytes of T. aurantium may perform a trophic role but their presence may also be interpreted as a means of transfer to the
 embryos. The lack of nurse cells around the oocytes suggests that yolk production in T. aurantium occurs by active uptake
 of nutrients from the mesohyl.

description: Africa, despite the natural wealth of its resources remains still at low development levels compared to the rest of the world. Given the importance of exports as a key factor for the economic development of African countries, we investigate whether international trade can create growth opportunities or whether there are "inherent weaknesses" that hinder this process. This paper presents and analyzes the foreign trade statistics of African countries, during the period 1995-2020. The topic is approached by analyzing recent trends and indicators of trade using the most up-to-date data from valid databases. The paper concludes that the structure of trade and in particular, the low export performance and the high export concentration in primary and natural resources (internal factors), combined with the volatility of the prices of these products in the international markets (external factors), make it extremely difficult for African economies to grow through international trade. In addition, Africa's participation in international production, as assessed by indicators that determine its position in the Global Value Chains, creates limited opportunities for technological upgrades, which is a critical factor in the development process.

description: Hamiltonian integration methods for the Vlasov-Maxwell equations are developed by a Hamiltonian splitting technique. The Hamiltonian functional is split into five parts, i.e., the electrical energy, the magnetic energy, and the kinetic energy in three Cartesian components. Each of the subsystems is a Hamiltonian system with respect to the Morrison-Marsden-Weinstein Poisson bracket and can be solved exactly. Compositions of the exact solutions yield Poisson structure preserving, or Hamiltonian, integration methods for the Vlasov-Maxwell equations, which have superior long-term fidelity and accuracy.

Relationship between the density distribution of intramembrane particles and electron transfer in the mitochondrial inner membrane as revealed by cholesterol incorporation

description: A low pH method of liposome-membrane fusion (Schneider et al., 1980, Proc. Natl. Acad. Sci. U. S. A. 77:442) was used to enrich the mitochondrial inner membrane lipid bilayer 30-700% with exogenous phospholipid and cholesterol. By varying the phospholipid-to- cholesterol ratio of the liposomes it was possible to incorporate specific amounts of cholesterol (up to 44 mol %) into the inner membrane bilayer in a controlled fashion. The membrane surface area increased proportionally to the increase in total membrane bilayer lipid. Inner membrane enriched with phospholipid only, or with phospholipid plus cholesterol up to 20 mol %, showed randomly distributed intramembrane particles (integral proteins) in the membrane plane, and the average distance between intramembrane particles increased proportionally to the amount of newly incorporated lipid. Membranes containing between 20 and 27 mol % cholesterol exhibited small clusters of intramembrane particles while cholesterol contents above 27 mol % resulted in larger aggregations of intramembrane particles. In phospholipid-enriched membranes with randomly dispersed intramembrane particles, electron transfer activities from NADH- and succinate-dehydrogenase to cytochrome c decreased proportionally to the increase in distance between the particles. In contrast, these electron- transfer activities increased with decreasing distances between intramembrane particles brought about by cholesterol incorporation. These results indicate that (a) catalytically interacting redox components in the mitochondrial inner membrane such as the dehydrogenase complexes, ubiquinone, and heme proteins are independent, laterally diffusible components; (b) the average distance between these redox components is effected by the available surface area of the membrane lipid bilayer; and (c) the distance over which redox components diffuse before collision and electron transfer mediates the rate of such transfer.

description: This study analyzes the vertical and horizontal distribution of pteropod mollusks in the neritic waters from the southern Gulf of Mexico. A total of 187 plankton samples were collected at five strata within the water column (0-6, 6-12, 12-18, 45-55, and 95-105 m) over a grid of 28 oceanographic stations using an opening-closing net system during May and November 1995. In total, 27 pteropod species were identified, from which Creseis clava (57%), Limacina inflata (18%), L. trochiformis (13%) and C. virgula (7%) were the most abundant species, accounting for almost 95% of the total abundance. Horizontally, these species had a wide distribution over the shelf waters, and vertically, the major pteropod densities were recorded in the 0-18 m upper layer. The congeneric species L. trochiformis and L. inflata registered their highest abundance in May and November respectively, suggesting a pattern of seasonal dominance to avoid competition for feeding resources. The gymnosomes Cephalobrachia macrochaeta, Notobranchaea macdonaldi and Pneumoderma violaceum registered the lowest abundances, likely related to their highly specialized diets. The species Cephalobrachia macrochaeta and Corolla intermedia were recorded for the first time in the western Atlantic. Worldwide distribution of the 27 pteropod species is exhaustively documented.
Neanthes nubila (Annelida: Polychaeta) - a review of its biogeography and breeding habits

description: Neanthes nubila (often cited as Nereis irrorata) is distributed in the Eastern Atlantic from Sweden to Morocco and the Canary Islands, including the southern British Isles and the Mediterranean Sea. This overlaps with the distribution of the similar N. rubicunda in the Azores, Madeira, Canaries and Mediterranean, so earlier records of these species from these areas will need checking. Neanthes nubila is usually found in fragile tubes in mud, from between the tides to shallow depths. Swarming mostly takes place just above the sea bed, although low numbers of epitokes can be found at the surface or on the shore. These data may also show that more northerly populations swarm earlier in the year than more southerly ones. The species may be able to withstand low salinities.

description: The secrecy rate represents the amount of information per unit time that can be securely sent on a communication link. In this work, we investigate the achievable secrecy rates in an energy harvesting communication system composed of a transmitter, a receiver and a malicious eavesdropper. In particular, because of the energy constraints and the channel conditions, it is important to understand when a device should transmit and to optimize how much power should be used in order to improve security. Both full knowledge and partial knowledge of the channel are considered under a Nakagami fading scenario. We show that high secrecy rates can be obtained only with power and coding rate adaptation. Moreover, we highlight the importance of optimally dividing the transmission power in the frequency domain, and note that the optimal scheme provides high gains in secrecy rate over the uniform power splitting case. Analytically, we explain how to find the optimal policy and prove some of its properties. In our numerical evaluation, we discuss how the maximum achievable secrecy rate changes according to the various system parameters. Furthermore, we discuss the effects of a finite battery on the system performance and note that, in order to achieve high secrecy rates, it is not necessary to use very large batteries.

description: We examined the effects of hypoxia and reoxygenation in isolated, perfused rat livers. Hypoxia induced by a low rate of perfusion led to near anoxia confined to centrilobular regions of the liver lobule. Periportal regions remained normoxic. Within 15 min, anoxic centrilobular hepatocytes developed surface blebs that projected into sinusoids through endothelial fenestrations. Periportal hepatocytes were unaffected. Both scanning and transmission electron microscopy suggested that blebs developed by transformation of preexisting microvilli. Upon reoxygenation by restoration of a high rate of perfusion, blebs disappeared. Other changes included marked shrinkage of hepatocytes, enlargement of sinusoids, and dilation of sinusoidal fenestrations. There was also an abrupt increase in the release of lactate dehydrogenase and protein after reoxygenation, and cytoplasmic fragments corresponding in size and shape to blebs were recovered by filtration of the effluent perfusate. We also studied phalloidin and cytochalasin D, agents that disrupt the cytoskeleton. Both substances at micromolar concentrations caused rapid and profound alterations of cell surface topography. We conclude that hepatic tissue is quite vulnerable to hypoxic injury. The morphological expression of hypoxic injury seems mediated by changes in the cortical cytoskeleton. Reoxygenation causes disappearance of blebs and paradoxically causes disruption of cellular volume control and release of blebs as cytoplasmic fragments. Such cytoplasmic shedding provides a mechanism for selective release of hepatic enzymes by injured liver tissue.

description: Drawing on balanced panel data of 6 Southern African countries in 1978–2019, this paper examines the impact of industrialisation on economic growth using several econometrics methods: pooled mean group, mean group, dynamic fixed effects and takes account of common correlated effects. Estimation is conducted using manufacturing value added as the proxy for industrialisation. Empirical results reveal that an increase in industrialisation is positively associated with economic growth in both the short and long-run and the positive relationship is more significant when we use common correlated factors to address the issue of cross-sectional dependence. The policy implications of this research are that industrialisation remains one of the important tools of economic transformation in Southern Africa and the successful implementation of the industrialisation strategies in the countries of Southern Africa is one of the clear pathways to economic development.

description: In this paper, we use data collected from over 2000 non-residential electric vehicle supply equipments (EVSEs) located in Northern California for the year of 2013 to estimate the potential benefits of smart electric vehicle (EV) charging. We develop a smart charging framework to identify the benefits of non-residential EV charging to the load aggregators and the distribution grid. Using this extensive dataset, we aim to improve upon past studies focusing on the benefits of smart EV charging by relaxing the assumptions made in these studies regarding: (i) driving patterns, driver behavior and driver types; (ii) the scalability of a limited number of simulated vehicles to represent different load aggregation points in the power system with different customer characteristics; and (iii) the charging profile of EVs. First, we study the benefits of EV aggregations behind-the-meter, where a time-of-use pricing schema is used to understand the benefits to the owner when EV aggregations shift load from high cost periods to lower cost periods. For the year of 2013, we show a reduction of up to 24.8% in the monthly bill is possible. Then, following a similar aggregation strategy, we show that EV aggregations decrease their contribution to the system peak load by approximately 40% when charging is controlled within arrival and departure times. Our results also show that it could be expected to shift approximately 0.25kWh (~2.8%) of energy per non-residential EV charging session from peak periods (12PM-6PM) to off-peak periods (after 6PM) in Northern California for the year of 2013.

Precise determination of the Higgs mass in supersymmetric models with vectorlike tops and the impact on naturalness in minimal GMSB

description: We present a precise analysis of the Higgs mass corrections stemming from vectorlike top partners in supersymmetric models. We reduce the theoretical uncertainty compared to previous studies in the following aspects: (i) including the one-loop threshold corrections to SM gauge and Yukawa couplings due to the presence of the new states to obtain the $\bar{\text{DR}}$ parameters entering all loop calculations, (ii) including the full momentum dependence at one-loop, and (iii) including all two-loop corrections but the ones involving $g_1$ and $g_2$. We find that the additional threshold corrections are very important and can give the largest effect on the Higgs mass. However, we identify also parameter regions where the new two-loop effects can be more important than the ones of the MSSM and change the Higgs mass prediction by up to 10 GeV. This is for instance the case in the low $\tanβ$, small $M_A$ regime. We use these results to calculate the electroweak fine-tuning of an UV complete variant of this model. For this purpose, we add a complete $\textbf{10}$ and $\bar{\textbf{10}}$ representation of $SU(5)$ to the MSSM particle content. We embed this model in minimal Gauge Mediated Supersymmetry Breaking and calculate the electroweak fine-tuning with respect to all important parameters. It turns out that the limit on the gluino mass becomes more important for the fine-tuning than the Higgs mass measurements which is easily to satisfy in this setup.
