description: Models that reproduce the observed high-velocity clouds (HVCs) also predict clouds at lower radial velocities that may easily be confused with Galactic disk (|z| < 1 kpc) gas. We describe the first search for these low-velocity halo clouds (LVHCs) using IRAS data and the initial data from the Galactic Arecibo L-band Feed Array survey in HI (GALFA-HI). The technique is based upon the expectation that such clouds should, like HVCs, have very limited infrared thermal dust emission as compared to their HI column density. We describe our 'displacement-map' technique for robustly determining the dust-to-gas ratio of clouds and the associated errors that takes into account the significant scatter in the infrared flux from the Galactic disk gas. We find that there exist lower-velocity clouds that have extremely low dust-to-gas ratios, consistent with being in the Galactic halo - candidate LVHCs. We also confirm the lack of dust in many HVCs with the notable exception of complex M, which we consider to be the first detection of warm dust in HVCs. We do not confirm the previously reported detection of dust in complex C. In addition, we find that most Intermediate- and Low-Velocity clouds that are part of the Galactic disk have a higher 60 micron/100 micron flux ratio than is typically seen in Galactic HI, which is consistent with a previously proposed picture in which fast-moving Galactic clouds have smaller, hotter dust grains.

description: This paper explores low resource classifiers and features for the detection of bird activity, suitable for embedded Automatic Recording Units which are typically deployed for long term remote monitoring of bird populations. Features include low-level spectral parameters, statistical moments on pitch samples, and features derived from amplitude modulation. Performance is evaluated on several lightweight classifiers using the NIPS4Bplus dataset. Our experiments show that random forest classifiers perform best on this task, achieving an accuracy of 0.721 and an F1-Score of 0.604. We compare the results of our system against both a Convolutional Neural Network based detector, and standard MFCC features. Our experiments show that we can achieve equal or better performance in most metrics using features and models with a smaller computational cost and which are suitable for edge deployment.

Tagged-particle dynamics in a fluid adsorbed in a disordered porous solid: interplay between the diffusion-localization and liquid-glass transitions

description: A mode-coupling theory for the slow single-particle dynamics in fluids adsorbed in disordered porous media is derived, which complements previous work on the collective dynamics [V. Krakoviack, Phys. Rev. E 75, 031503 (2007)]. Its equations, like the previous ones, reflect the interplay between confinement-induced relaxation phenomena and glassy dynamics through the presence of two contributions in the slow part of the memory kernel, which are linear and quadratic in the density correlation functions, respectively. From numerical solutions for two simple models with pure hard core interactions, it is shown that two different scenarios result for the diffusion-localization transition, depending on the strength of the confinement. For weak confinement, this transition is discontinuous and coincides with the ideal glass transition, like in one-component bulk systems, while, for strong confinement, it is continuous and occurs before the collective dynamics gets nonergodic. In the latter case, the glass transition manifests itself as a secondary transition, which can be either continuous or discontinuous, in the already arrested single-particle dynamics. The main features of the anomalous dynamics found in the vicinity of all these transitions are reviewed and illustrated with detailed computations.

description: At first sight, the city of Zaragoza, one of the most ancient cities in Spain, would seem like the most unlikely place to conduct an experiment using digital technologies.
Instead, the recent arrival of the high speed train has made possible the development of a technologically innovative project that is bringing the city into the Information Age.
Known as the Milla Digital, the project aims to add digital technology to the everyday activities that take place in public spaces, making those spaces capable of giving information and providing meaningful experiences for everyone who would like to live and learn in Zaragoza. What the project is going to accomplish is the creation of a new kind of space that is both public and private, called “Open-Source City”. The hope is that this project will create an interactive relationship between the static form of the city and the vibrant desires of the citizens triggering a revolutionary process.

description: The oxidized Ag(111) surface has been studied by a combination of experimental and theoretical methods, scanning tunneling microscopy (STM), x-ray photoelectron spectroscopy (XPS), and density functional theory (DFT). A large variety of different surface structures is found, depending on the detailed preparation conditions. The observed structures fall into four classes: (a) individually chemisorbed atomic oxygen atoms, (b) three different oxygen overlayer structures, including the well-known p(4 x 4) phase, formed from the same Ag$_6$ and Ag$_{10}$ building blocks, (c) a c(4 x 8) structure not previously observed, and (d) at higher oxygen coverages structures characterized by stripes along the high-symmetry directions of the Ag(111) substrate. Our analysis provides a detailed explanation of the atomic-scale geometry of the Ag$_6$/Ag$_{10}$ building block structures, and the c(4 x 8) and stripe structures are discussed in detail. The observation of many different and co-existing structures implies that the O/Ag(111) system is characterized by a significantly larger degree of complexity than previously anticipated, and this will impact our understanding of oxidation catalysis processes on Ag catalysts.

A systems model of rural-urban migration in Nigeria
Creators: name: Odimuko, C. L.
Publisher: name: University of British Columbia
Year: 2010

description: Rural-urban migration in Nigeria is the cause of a number of problems; the problems of overcrowding and deterioration of the urban environment associated with rapid urban growth; the economic loss resulting from the high unemployment rates in urban areas; and the problem of adverse implications of prolonged periods of frustration among the urban, poor. Nigerian governments .recognize that rural-urban migration calls for more effective policies than those attempted in the past. In this context new approaches designed to foster greater understanding of the nature of this process and more effective policies should be helpful. This thesis proceeds on the premise that rural-urban migration is in reality a process within a complex socio-economic system consisting of many interacting components and significant feed-back effects. It is thus held that a General Systems Approach provides an appropriate and useful analytical framework for the study of this process. In addition to bringing a broader perspective to the analysis, a systems framework is a powerful tool for exploratory research and therefore well suited both to the promotion of a greater understanding of the process and for the generation of a number of initial policy considerations. Relying on material from existing literature and personal experience related to the process in south-eastern Nigeria, a model of rural-urban . migration is developed in Chapter 4 (Figures 4.1 and 4.2), and applied in Chapter 5 to derive a series of testable hypotheses related to the migration process. The methodology is demonstrative of a systematic procedure for generating a series of interrelated potential policies for shaping the process. The main thrust of the work is to develop a conceptual systems model of the rural-urban migration process and thus to lay a foundation for further, substantive research on rural-urban migration in Nigeria. In the concluding chapter, some directions for this future research have been sketched.

description: We investigate the decay of artificially created double occupancies in a repulsive Fermi-Hubbard system in the strongly interacting limit using diagrammatic many-body theory and experiments with ultracold fermions on optical lattices. The lifetime of the doublons is found to scale exponentially with the ratio of the on-site repulsion to the bandwidth. We show that the dominant decay process in presence of background holes is the excitation of a large number of particle hole pairs to absorb the energy of the doublon. We also show that the strongly interacting nature of the background state is crucial in obtaining the correct estimate of the doublon lifetime in these systems. The theoretical estimates and the experimental data are in fair quantitative agreement.

description: High-energy astrophysical neutrinos have been observed by several telescopes in the last decade, but their sources still remained unknown. We address the problem of locating astrophysical neutrinos' sources in a statistical manner. We show that blazars positionally associated with IceCube neutrino detections have stronger parsec-scale radio cores than the rest of the sample. The probability of a chance coincidence is only 4*10^-5 corresponding to a significance of 4.1 sigma. We explicitly list four strong radio blazars as highly probable sources of neutrinos above 200 TeV: 3C 279, NRAO 530, PKS 1741-038, and PKS 2145+067. There are at least 70 more radio-bright blazars that emit neutrinos of lower energies, starting from TeVs. Using continuous RATAN-600 monitoring of VLBI-selected blazars, we find that radio flares at frequencies above 10 GHz coincide with neutrino arrival dates. The most pronounced example of such behavior is PKS 1502+106 that experienced a major flare in 2019. We demonstrate that the majority of IceCube astrophysical neutrino flux derived from muon-track analyses may be explained by blazars, that is, AGNs with bright Doppler-boosted jets. High-energy neutrinos can be produced in photohadronic interactions within parsec-scale relativistic jets. Radio-bright blazars associated with neutrino detections have very diverse gamma-ray properties, which suggests that gamma-rays and neutrinos may be produced in different regions of blazars and not directly related. A narrow jet viewing angle is, however, required to detect either of them. We conclude with discussion of recent independent tests and extensions of our findings.

Recursive Quantum Number Theory
Creators: name: Monroe, Scott
Publisher: name: Zenodo
Year: 2025

description: Recursive Quantum Number (RQN) Theory proposes a new mathematical framework for encoding space-time as a time-evolving, energy-filtered number system. Extending classical ppp-adic arithmetic, RQNs introduce a dynamic scaling base tied to cosmic expansion and impose quantum energy thresholds on digit-level contributions. This results in a non-Archimedean, partially closed ring structure that evolves with time and reflects both hierarchical recursion and physical constraints.

The theory models space-time as a recursive arithmetic object, where each valid digit corresponds to a causally ordered, energy-permitted quantum event. RQNs support algebraic operations, recursive harmonic analysis, and filtered sheaf structures, while naturally embedding concepts from spin foam models, causal set theory, and holographic entropy bounds. The framework offers a novel arithmetic lens on discrete geometry, quantum gravity, and cosmological information flow.

description: We use lattice Boltzmann simulations, in conjunction with Ewald summation methods, to investigate the role of hydrodynamic interactions in colloidal suspensions of dipolar particles, such as ferrofluids. Our work addresses volume fractions $ϕ$ of up to 0.20 and dimensionless dipolar interaction parameters $λ$ of up to 8. We compare quantitatively with Brownian dynamics simulations, in which many-body hydrodynamic interactions are absent. Monte Carlo data are also used to check the accuracy of static properties measured with the lattice Boltzmann technique. At equilibrium, hydrodynamic interactions slow down both the long-time and the short-time decays of the intermediate scattering function $S(q,t)$, for wavevectors close to the peak of the static structure factor $S(q)$, by a factor of roughly two. The long-time slowing is diminished at high interaction strengths whereas the short-time slowing (quantified via the hydrodynamic factor $H(q)$) is less affected by the dipolar interactions, despite their strong effect on the pair distribution function arising from cluster formation. Cluster formation is also studied in transient data following a quench from $λ= 0$; hydrodynamic interactions slow the formation rate, again by a factor of roughly two.

The influence of star clusters on galactic disks: new insights on star-formation in galaxies
Creators: name: Kroupa, Pavel
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Stars form in embedded star clusters which play a key role in determining the properties of a galaxy's stellar population. Physical mechanisms discussed in this paper are runaway stars shot out from young clusters, binary-star disruption in clusters, gas blow-out from clusters and the origin of thick galactic disks. I emphasise that the SNIa rate per low-mass star depends on the star-clusters formed in a galaxy and I discuss the IGIMF theory. Based on the IGIMF theory, the re-calibrated Halpha-luminosity--SFR relation implies dwarf irregular galaxies to have the same gas-depletion time-scale as major disk galaxies, suggesting a major change in our understanding of dwarf-galaxy evolution. The IGIMF-theory also naturally leads to the observed radial Halpha cutoff in disk galaxies without a radial star-formation cutoff. It emerges that the thorough understanding of the physics and distribution of star clusters may be leading to a major paradigm shift in our understanding of galaxy evolution.

description: We investigate the transition to synchronization in the Kuramoto model with bimodal distributions of the natural frequencies. Previous studies have concluded that the model exhibits a hysteretic phase transition if the bimodal distribution is close to a unimodal one, due to the shallowness the central dip. Here we show that proximity to the unimodal-bimodal border does not necessarily imply hysteresis when the width, but not the depth, of the central dip tends to zero. We draw this conclusion from a detailed study of the Kuramoto model with a suitable family of bimodal distributions.

description: Fluorescence lifetimes of nitrogen-vacancy color centers in individual diamond nanocrystals were measured at the interface between a glass substrate and a strongly scattering medium. Comparison of the results with values recorded from the same nanocrystals at the glass-air interface revealed fluctuations of fluorescence lifetimes in the scattering medium. After discussing a range of possible systematic effects, we attribute the observed lengthening of the lifetimes to the reduction of the local density of states. Our approach is very promising for exploring the strong three-dimensional localization of light directly on the microscopic scale.

Byronism in Lermontov’s A hero of our time
Creators: name: Cameron, Alan Harwood
Publisher: name: University of British Columbia
Year: 2010

description: Although Mikhail Lermontov is commonly known as the "Russian Byron," up to this point no examination of the Byronic features of A Hero of Our Time, (Geroy nashego vremeni)3 has been made. This study presents the view that, while the novel is much more than a simple expression of Byronism, understanding the basic Byronic traits and Lermontov1s own modification of them is essential for a true comprehension of the novel. Each of the first five chapters is devoted to a scrutiny of the separate tales that make up A Hero of Our Time. The basic Byronic motifs of storms, poses and exotic settings are examined in each part with commentary on some Lermontovian variations on them. The secondary figures, heroines, "pashas," villains and others are also assessed against Byronic tradition. Finally, the different presentations of Pechorin, the main figure, are analyzed and evaluated to determine how the hero is and is not "Byronic." To ascertain exactly what the hero's Byronic features might be, I have used^P.J. Thorslev's system of prototypes for the Byronic hero, who could have any or all of the traits of the Child of Nature, the Hero of Sensibility or the Gothic Villain. By determining how Pechorin fits into these categories, it is easy to see in what way he resembles a Byronic hero. The first chapter deals with Princess Mary and shows how Pechorin's love of nature, egocentric sensitivity and nostalgic musings are part of the Byronic mainstream, yet how his cruel penchant for evil constitutes a modification. Chapter Two, on Beta, demonstrates Lermontov's alterations of the fundamental Byronic love formula; in the next chapter; which concerns Maksim Maksimych I have shown how the focal point of that story, Pechorin's external description, is strikingly Byronic. Chapter Four presents a new interpretation of Taman ' as a parody on the heroic myth of infallibility. The second last chapter points out how the Byronism of The Fatalist is filtered through the actions of the story and how Pechorin reconciles the belief in his own free will with the concept of fatalism. Chapter Six concludes the study with a view of the novel as a whole and a summation of the Byronic features of A Hero of Our Time,

description: RESUMO

O presente artigo analisa a distribuição de papéis no sistema acusatório brasileiro, com foco na incompatibilidade de determinados artigos do Código de Processo Penal com esse sistema. O sistema acusatório é aquele em que as funções de investigação, acusação e julgamento estão separadas, sendo exercidas por agentes distintos. O sistema inquisitorial, por outro lado, é aquele em que as três funções estão concentradas nas mãos de uma única pessoa, o juiz. A Constituição Federal de 1988 adotou o sistema acusatório, pois o art. 129, I, da Constituição atribui ao Ministério Público à função privativa de promover a ação penal pública. O sistema acusatório é o sistema mais adequado a garantir os direitos e garantias fundamentais do acusado, como o contraditório e a ampla defesa. No entanto, o Código de Processo Penal, promulgado em 1941, ainda carrega resquícios do sistema inquisitorial. Alguns artigos são incompatíveis com o sistema acusatório, pois permitem ao juiz atuar como acusador, violando o princípio da imparcialidade, estes artigos podem levar a condenações injustas. O Código de Processo Penal deve ser alterado para eliminar os resquícios do sistema inquisitorial e garantir plenamente o sistema acusatório.

description: Mauro Cardi addresses the implications of the development of technologies and networking on the ‘work’ of the composer and the influence they exert on the modalities of ‘generation’, reception and fruition of musical texts, both in terms of social impact, and of mechanisms and practices they produce. Where the greater availability of resources proves to offer opportunities hard to imagine before, the problems that are created extend their range. It therefore remains the inescapable need for the composer to design his own instruments, in order to maintain a fully active role in the choices required by his work.

description: We investigate the stability of strings connecting charges Q in the representation {2Q+1} of SU(2) Yang-Mills theory in (2+1) dimensions. While the fundamental {2}-string between two charges Q=1/2 is unbreakable and stable, the string connecting static charges transforming under any other representation Q>1/2 is unstable and decays. A charge Q=1 can be completely screened by gluons and so the adjoint {3}-string ultimately breaks. A charge Q=3/2 can be only partially screened to a fundamental charge Q=1/2. Thus, stretching a {4}-string beyond a critical length, it decays into the stable {2}-string by gluon pair creation. The complete breaking of a {5}-string happens in two steps, it first decays into a {3}-string and then breaks completely. A phenomenological constituent gluon model provides a good quantitative description of the energy of the screened charges at the ends of an unstable string.

The synonymisation of E. pyrenaeus (Simon, 1914) with E. theridioides by Bosmans and de Castro (2002) is supported by the present material from the Pyrenees and from Corsica, though only females have been compared. General appearance (Fig. 27), shape of epigynum and overall course of copulatory ducts (Figs 28-29) are not or barely different from E. theridioides (Figs 30-31). Distribution. Episinus theridioides occurs discontinuously in the Mediterranean (Knoflach and Thaler 2000) and is known only from a few localities in the French and Spanish Pyrenees, Cantabria, Corsica and Sardinia; for a distribution map see Bosmans and de Castro (2002). Unlike members of the E. truncatus -group it appears to be an exclusively epigeic species.

description: Achieving the decarbonisation of energy-intensive industries (EIIs) by mid-century is technically possible and essential to achieving the aims of the Paris Agreement. However, decarbonising EIIs, such as steel, cement, chemicals, and aluminium, faces significant economic, political, and structural barriers across all levels of governance. This study systematically analyses national sectoral decarbonisation barriers, enablers and policies for 13 major EII producing countries to assess if their respective national policy frameworks are fit for advancing the decarbonisation of EIIs in line with Paris-compatible pathways. The analysis is based on case studies that systematically map national sectoral mitigation barriers, enablers and policies conducted or reviewed by national or sectoral experts.

description: Using a homogenous sample of 38,208 quasars with a sky coverage of $4000 {\rm deg^2}$ drawn from the SDSS Data Release Five quasar catalog, we study the dependence of quasar clustering on luminosity, virial black hole mass, quasar color, and radio loudness. At $z<2.5$, quasar clustering depends weakly on luminosity and virial black hole mass, with typical uncertainty levels $\sim 10%$ for the measured correlation lengths. These weak dependences are consistent with models in which substantial scatter between quasar luminosity, virial black hole mass and the host dark matter halo mass has diluted any clustering difference, where halo mass is assumed to be the relevant quantity that best correlates with clustering strength. However, the most luminous and most massive quasars are more strongly clustered (at the $\sim 2σ$ level) than the remainder of the sample, which we attribute to the rapid increase of the bias factor at the high-mass end of host halos. We do not observe a strong dependence of clustering strength on quasar colors within our sample. On the other hand, radio-loud quasars are more strongly clustered than are radio-quiet quasars matched in redshift and optical luminosity (or virial black hole mass), consistent with local observations of radio galaxies and radio-loud type 2 AGN. Thus radio-loud quasars reside in more massive and denser environments in the biased halo clustering picture. Using the Sheth et al.(2001) formula for the linear halo bias, the estimated host halo mass for radio-loud quasars is $\sim 10^{13} h^{-1}M_\odot$, compared to $\sim 2\times 10^{12} h^{-1}M_\odot$ for radio-quiet quasar hosts at $z\sim 1.5$.

description: Multiferroics, materials where spontaneous long-range magnetic and dipolar orders coexist, represent an attractive class of compounds, which combine rich and fascinating fundamental physics with a technologically appealing potential for applications in the general area of spintronics. Ab-initio calculations have significantly contributed to recent progress in this area, by elucidating different mechanisms for multiferroicity and providing essential information on various compounds where these effects are manifestly at play. In particular, here we present examples of density-functional theory investigations for two main classes of materials: a) proper multiferroics (where ferroelectricity is driven by hybridization or purely structural effects), with BiFeO_3 as prototype material, and b) improper multiferroics (where ferroelectricity is driven by correlation effects and is strongly linked to electronic degrees of freedom such as spin, charge, or orbital ordering), with rare-earth manganites as prototypes.

MAIN ISSUES IN THE SPHERE OF INTERNATIONAL LEGAL REGULATION OF ARTIFICIAL INTELLIGENCE

Publisher: name: Zenodo
Year: 2024

description: The article is devoted to an overview of key issues related to the legal regulation of artificial intelligence. The author notes that there are no unified positions regarding the legal regulation of AI. One group of scientists considers the legal regulation of AI necessary, while others warn that excessive regulation may hinder the development of AI. The article highlights the following key issues: the content of the concept of "artificial intelligence" (AI), the legal personality of AI, i.e. the issue of recognizing AI as a subject of law, the liability of AI in the event of harm. The author notes that at the moment there are many definitions of AI, the issue of recognizing AI as a subject has not been resolved unambiguously, however, the so-called theory of fictitious legal personality of artificial intelligence prevails, which assumes giving the legal status of AI certain features inherent in the status of legal entities. The article provides examples of legal regulations in the EU, as well as examples of cases from judicial practice on the recognition of AI as a subject of law.
Rapid bursts of magnetically gated accretion in the intermediate polar V1025 Cen

description: Magnetically gated accretion has emerged as a proposed mechanism for producing extremely short, repetitive bursts of accretion onto magnetized white dwarfs in intermediate polars (IPs), but this phenomenon has not been detected previously in a confirmed IP. We report the 27-day TESS light curve of V1025 Cen, an IP that shows a remarkable series of twelve bursts of accretion, each lasting for less than six hours. The extreme brevity of the bursts and their short recurrence times (~1-3 days) are incompatible with the dwarf-nova instability, but they are natural consequences of the magnetic gating mechanism developed by Spruit & Taam to explain the Type II bursts of the accreting neutron star known as the Rapid Burster. In this model, the accretion flow piles up at the magnetospheric boundary and presses inward until it couples with the star's magnetic field, producing an abrupt burst of accretion. After each burst, the reservoir of matter at the edge of the magnetosphere is replenished, leading to cyclical bursts of accretion. A pair of recent studies applied this instability to the suspected IPs MV Lyr and TW Pic, but the magnetic nature of these two systems has not been independently confirmed. In contrast, previous studies have unambiguously established the white dwarf in V1025 Cen to be significantly magnetized. The detection of magnetically gated bursts in a confirmed IP therefore validates the extension of the Spruit & Taam instability to magnetized white dwarfs.

ENHANCING SCREENING AND MANAGEMENT OF DELIRIUM IN CRITICAL CARE

description: Delirium is a major health issue for critically ill patients. Delirium is characterized by a change in level of cognition with disorganized thinking, and can result in cognitive impairment if undiagnosed and treated. Without screening, greater than 66% of patients with delirium may go undiagnosed, and cognitive impairment upon discharge is 10-fold higher for undiagnosed patients. Use of the Confusion Assessment Method in Intensive Care Unit (CAM-ICU) is known to optimize identification of delirium among critically ill patients. Despite staff training and adoption of the CAM-ICU tool in 2014 in critical care units of a southwestern Magnet-accredited faith-based community hospital, chart audits found that unit staff was inconsistently screening and managing delirium. Nurses stated that the tool was complicated and time-consuming. Following a literature review, an educational program was developed to address the problem. The program is composed of a self-learning module (SLM) with pre- and post-test to be followed by supervised bedside application of the tool, and skills evaluation using a competency checklist. Also developed was a reference and resource manual to be kept on the unit. The program has been approved by the unit manager and clinical nurse specialist (CNS), and will be piloted on five nurses during summer 2018. The five nurses will become the nurse champions for this program. The program will be given to the remaining nurses of the unit after the pilot. A post-program assessment will iv determine the prevalence of delirium in the unit, data which has not been available to date. Enhancing nurses’ skill in identifying presence of delirium will optimize the management of delirium in critical care. This educational program for staff should improve patient care for critically ill patients.

From reversing to hemispherical dynamos

description: We show that hemispherical dynamos can result from weak equatorial symmetry breaking of the flow in the interior of planets and stars. Using a model of spherical dynamo, we observe that the interaction between a dipolar and a quadrupolar mode can localize the magnetic field in only one hemisphere when the equatorial symmetry is broken. This process is shown to be related to the one that is responsible for reversals of the magnetic field. These seemingly very different behaviors are thus understood in a unified framework.
Testing SUSY at the LHC: Electroweak and Dark matter fine tuning at two-loop order

description: In the framework of the Constrained Minimal Supersymmetric Standard Model (CMSSM) we evaluate the electroweak fine tuning measure that provides a quantitative test of supersymmetry as a solution to the hierarchy problem. Taking account of current experimental constraints we compute the fine tuning at two-loop order and determine the limits on the CMSSM parameter space and the measurements at the LHC most relevant in covering it. Without imposing the LEPII bound on the Higgs mass, it is shown that the fine tuning computed at two-loop has a minimum $Δ=8.8$ corresponding to a Higgs mass $m_h=114\pm 2$ GeV. Adding the constraint that the SUSY dark matter relic density should be within present bounds we find $Δ=15$ corresponding to $m_h=114.7\pm 2$ GeV and this rises to $Δ=17.8$ ($m_h=115.9\pm 2$ GeV) for SUSY dark matter abundance within 3$σ$ of the WMAP constraint. We extend the analysis to include the contribution of dark matter fine tuning. In this case the overall fine tuning and Higgs mass are only marginally larger for the case SUSY dark matter is subdominant and rises to $Δ=28.7$ ($m_h=116.98\pm 2$ GeV) for the case of SUSY dark matter saturates the WMAP bound. For a Higgs mass above these values, fine tuning rises exponentially fast. The CMSSM spectrum that corresponds to minimal fine tuning is computed and provides a benchmark for future searches. It is characterised by heavy squarks and sleptons and light neutralinos, charginos and gluinos.
