description: In this paper, we consider massive multiple-input multiple-output (MIMO) systems for both downlink and uplink scenarios, where three radio units (RUs) connected via one digital unit (DU) support multiple user equipments (UEs) at the cell-boundary through the same radio resource, i.e., the same time-frequency slot. For downlink transmitter options, the study considers zero-forcing (ZF) and maximum ratio transmission (MRT), while for uplink receiver options it considers ZF and maximum ratio combining (MRC). For the sum rate of each of these, we derive simple closed-form formulas. In the simple but practically relevant case where uniform power is allocated to all downlink data streams, we observe that, for the downlink, vector normalization is better for ZF while matrix normalization is better for MRT. For a given antenna and user configuration, we also derive analytically the signal-to-noise-ratio (SNR) level below which MRC should be used instead of ZF. Numerical simulations confirm our analytical results.

description: The authors demonstrated that L21-ordered full-Heusler Co2FeSi (CFS) alloy film with thickness of 100 nm were formed by facing targets sputtering (FTS) method at a substrate temperature TS = 300 deg C. Degrees of L21- and B2- order for the film were 0.37, and 0.96, respectively. Furthermore, full-Heusler CFS alloy thin films with perpendicular magnetic anisotropy (PMA) induced by MgO-interface magnetic anisotropy were successfully formed by the FTS method. The CFS/MgO stacking layers showed PMA when dCFS was 0.6 nm <= dCFS <= 1.0 nm. The PMA in these structures resulted from the CFS/MgO interfacial perpendicular magnetic anisotropy.

description: The fully quantum reverse Shannon theorem establishes the optimal rate of noiseless classical communication required for simulating the action of many instances of a noisy quantum channel on an arbitrary input state, while also allowing for an arbitrary amount of shared entanglement of an arbitrary form. Turning this theorem around establishes a strong converse for the entanglement-assisted classical capacity of any quantum channel. This paper proves the strong converse for entanglement-assisted capacity by a completely different approach and identifies a bound on the strong converse exponent for this task. Namely, we exploit the recent entanglement-assisted "meta-converse" theorem of Matthews and Wehner, several properties of the recently established sandwiched Renyi relative entropy (also referred to as the quantum Renyi divergence), and the multiplicativity of completely bounded $p$-norms due to Devetak et al. The proof here demonstrates the extent to which the Arimoto approach can be helpful in proving strong converse theorems, it provides an operational relevance for the multiplicativity result of Devetak et al., and it adds to the growing body of evidence that the sandwiched Renyi relative entropy is the correct quantum generalization of the classical concept for all $α>1$.

description: The purpose of this work is to implement physics-based regularization as a stopping condition in tuning an untrained deep neural network for reconstructing MR images from accelerated data. The ConvDecoder neural network was trained with a physics-based regularization term incorporating the spoiled gradient echo equation that describes variable-flip angle (VFA) data. Fully-sampled VFA k-space data were retrospectively accelerated by factors of R={8,12,18,36} and reconstructed with ConvDecoder (CD), ConvDecoder with the proposed regularization (CD+r), locally low-rank (LR) reconstruction, and compressed sensing with L1-wavelet regularization (L1). Final images from CD+r training were evaluated at the \emph{argmin} of the regularization loss; whereas the CD, LR, and L1 reconstructions were chosen optimally based on ground truth data. The performance measures used were the normalized root-mean square error, the concordance correlation coefficient (CCC), and the structural similarity index (SSIM). The CD+r reconstructions, chosen using the stopping condition, yielded SSIMs that were similar to the CD (p=0.47) and LR SSIMs (p=0.95) across R and that were significantly higher than the L1 SSIMs (p=0.04). The CCC values for the CD+r T1 maps across all R and subjects were greater than those corresponding to the L1 (p=0.15) and LR (p=0.13) T1 maps, respectively. For R > 12 (<4.2 minutes scan time), L1 and LR T1 maps exhibit a loss of spatially refined details compared to CD+r. We conclude that the use of an untrained neural network together with a physics-based regularization loss shows promise as a measure for determining the optimal stopping point in training without relying on fully-sampled ground truth data.

description: Complementary metal-oxide semiconductor (CMOS) technology has radically reshaped the world by taking humanity to the digital age. Cramming more transistors into the same physical space has enabled an exponential increase in computational performance, a strategy that has been recently hampered by the increasing complexity and cost of miniaturization. To continue achieving significant gains in computing performance, new computing paradigms, such as quantum computing, must be developed. However, finding the optimal physical system to process quantum information, and scale it up to the large number of qubits necessary to build a general-purpose quantum computer, remains a significant challenge. Recent breakthroughs in nanodevice engineering have shown that qubits can now be manufactured in a similar fashion to silicon field-effect transistors, opening an opportunity to leverage the know-how of the CMOS industry to address the scaling challenge. In this article, we focus on the analysis of the scaling prospects of quantum computing systems based on CMOS technology.

Exact 3D solution for static and damped harmonic response of simply supported general laminates
Creators: name: Loredo, Alexandre
Publisher: name: arXiv
Year: 2013
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: The state-space method is adapted to obtain three dimensional exact solutions for the static and damped dynamic behaviors of simply supported general laminates. The state-space method is written in a general form that permits to handle both cross-ply and antisymmetric angle-ply laminates. This general form also permits to obtain exact solutions for general laminates, albeit with some constraints. For the general case and for the static behavior, either an additive term is added to the load to simulate simply supported boundary conditions, or the plate bends in a particular way. For the dynamic behavior, the general case leads to pairs of natural frequencies for each order, with associated mode shapes. Finite element simulations have been performed to validate most of the results presented in this study. As the boundary conditions needed for the general case are not so straightforward, a specific discussion has been added. It is shown that these boundary conditions also work for the two aforementioned laminate classes. The damped harmonic response of a non symmetrical isotropic sandwich is studied for different frequencies around the fundamental frequency. The static and undamped dynamic behaviors of the [-15/15], [0/30/0] and [-10/0/40] laminates are studied for various length-to-thickness ratios.

description: Variable selection is considered in the setting of supervised binary classification with functional data $\{X(t),\ t\in[0,1]\}$. By "variable selection" we mean any dimension-reduction method which leads to replace the whole trajectory $\{X(t),\ t\in[0,1]\}$, with a low-dimensional vector $(X(t_1),\ldots,X(t_k))$ still keeping a similar classification error. Our proposal for variable selection is based on the idea of selecting the local maxima $(t_1,\ldots,t_k)$ of the function ${\mathcal V}_X^2(t)={\mathcal V}^2(X(t),Y)$, where ${\mathcal V}$ denotes the "distance covariance" association measure for random variables due to Székely, Rizzo and Bakirov (2007). This method provides a simple natural way to deal with the relevance vs. redundancy trade-off which typically appears in variable selection. This paper includes (a) Some theoretical motivation: a result of consistent estimation on the maxima of ${\mathcal V}_X^2$ is shown. We also show different theoretical models for the underlying process $X(t)$ under which the relevant information in concentrated in the maxima of ${\mathcal V}_X^2$. (b) An extensive empirical study, including about 400 simulated models and real data examples, aimed at comparing our variable selection method with other standard proposals for dimension reduction.

description: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease in which patients frequently experience pain. To improve treatments and advance pain management in SLE, we characterized pain in patients with SLE through a biopsychosocial lens, taking into account demographics, socioeconomic status, comorbidities, chronic overlapping pain conditions (COPCs), mental health, other pain conditions, distribution of pain regions, and other measurements of pain and well-being. We investigated two research questions: 1. What distinguishes patients with SLE who are seen at the pain clinics and are in CHOIR, the Collaborative Health Outcomes Information Registry, from patients with SLE who are not seen at the pain clinics? and 2. What are the biopsychosocial correlates of pain in the patients with SLE seen at the pain clinics (in CHOIR)? Our cross-sectional regression analyses indicated that patients with SLE at CHOIR are more likely to be on public health insurance, to be Black, and have COPCs, mental health conditions, and functional comorbidities compared to patients with SLE who were not in CHOIR. Further, within the cohort of patients with SLE in CHOIR, pain widespreadness was significantly associated with worse PROMIS measures, pain intensity, and pain catastrophizing. In addition, socioeconomic status was significantly associated with average pain intensity. Ultimately, this work will lay the foundation for developing more targeted interventions or informing clinical practice to minimize and treat chronic pain in patients with SLE.

description: Domain walls in correlated charge density wave compounds such as 1T-TaS2 can have distinct localized states which govern physical properties and functionalities of emerging quantum phases. However, detailed atomic and electronic structures of domain walls have largely been elusive. We identify using scanning tunneling microscope and density functional theory calculations the atomic and electronic structures for a plethora of discommensuration domain walls in 1T-TaS2 quenched metastably with nanoscale domain wall networks. The domain walls exhibit various in-gap states within the Mott gap but metallic states appear in only particular types of domain walls. A systematic understanding of the domain-wall electronic property requests not only the electron counting but also including various intertwined interactions such as structural relaxation, electron correlation, and charge transfer. This work guides the domain wall engineering of the functionality in correlated van der Waals materials.

description: Hamun Lake, the greatest (>8500 km2) freshwater in the Iran plateau, has almost entirely dried over the last 20 years. The flow of the Hirmand (or Helmand) River, the most important feeding river, has decreased from 4.0 to 1.9 km3 in the border of Iran-Afghanistan. In this river basin, the annual water consumption for irrigation is over 90% of the total consumed water. This study aims to calculate the increase in agricultural water consumption in the last two decades. Due to the lack of in-situ data across Afghanistan (including ∼80% of the studied area), this research utilizes remote-sensing. Using Google Earth Engine, land use maps for the years 2002, 2008, 2013, 2017, and 2021 were developed by a supervised classification scheme. Since 2002, it was found that the cropland area has increased from 2008 to 5475 km2. Most cropland has been developed around the Kajaki dam. Based on the Penman-Monteith-Leuning Evapotranspiration version 2 (PML V2) actual evapotranspiration (AET) data (our model assumes the irrigation efficiency equal to 0.3), the annual consumed water has increased from 2 to over 6 km3 in the last two decades. The presented framework in this study can be recommended for other ungauged basins.

description: We study a model for a non-singular cosmic bounce in N=1 supergravity, based on supergravity versions of the ghost condensate and cubic Galileon scalar field theories. The bounce is preceded by an ekpyrotic contracting phase which prevents the growth of anisotropies in the approach to the bounce, and allows for the generation of scale-invariant density perturbations that carry over into the expanding phase of the universe. We present the conditions required for the bounce to be free of ghost excitations, as well as the tunings that are necessary in order for the model to be in agreement with cosmological observations. All of these conditions can be met. Our model thus provides a proof-of-principle that non-singular bounces are viable in supergravity, despite the fact that during the bounce the null energy condition is violated.

description: This action research study aims to explore and resolve the extant problem situation relating to the Social Benefit System (SBS) development project involving two different Ministries within The Sultanate of Oman (i.e. Ministry of Social Development (MOSD); Ministry of National Economy (MONE)). The intention is to propose an appropriate approach to Information Systems Planning (ISP) intended to increase the success rate of Information Systems (IS) and Information Technology (IT) projects within Omani governmental organisations. The underlying purpose concerns identifying Socio-Technical risks at the ISP stage and how these could influence the success rate of governmental IS. The literature review confirmed the suitability of utilising Leavitt's (1964) Socio-Technical Model of organisational change as an appropriate methodology to investigate and analyse the reasons behind the problem situation in the research context. Using Leavitt's Model, the first action research, which involved two cycles, put forward an extended model aimed at identifying how resistance evolved during ISP stages within one organisational context (MOSD) while applying change. The second action research involved the two different environments (MOSD; MONE) through an Integrated Steering Committee. Therefore, Leavitt Model required an extension due to the effect of cultural and organisational differences before using it as a tool to define and place the gaps. Using the proposed extended Model the second action research, which also involved two cycles, puts forward a Model aimed at identifying how conflict evolved within Integrated Steering Committees.This study concludes with presenting an approach to ISP intended to increase the success rate of IS/IT projects in Omani governmental organisations. In this way, this study endeavours to contribute to the body of knowledge within the IS management domain in DCs and provides rich insights into how socio-technical risk factors evolve during the ISP stage of IS/IT projects within DCs.

description: We consider the transport of gas in long pipes and pipeline networks for which the dynamics are dominated by friction at the pipe walls. The governing equations can be formulated as an abstract dissipative Hamiltonian system which allows us to derive perturbation bounds by means of relative energy estimates. As particular consequences, we obtain stability with respect to initial conditions and model parameters and quantitative estimates in the high friction limit. Our results are established in detail for the flow in a single pipe and through the energy-based modelling they naturally generalize also to pipe networks.
Hunt for Light Primordial Black Hole Dark Matter with Ultra-High-Frequency Gravitational Waves

description: Light primordial black holes may comprise a dominant fraction of the dark matter in our Universe. This paper critically assesses whether planned and future gravitational wave detectors in the ultra-high-frequency band could constrain the fraction of dark matter composed of sub-solar primordial black holes. Adopting the state-of-the-art description of primordial black hole merger rates, we compare various signals with currently operating and planned detectors. As already noted in the literature, our findings confirm that detecting individual primordial black hole mergers with currently existing and operating proposals remains difficult. Current proposals involving gravitational wave to electromagnetic wave conversion in a static magnetic field and microwave cavities feature a technology gap with respect to the loudest gravitational wave signals from primordial black holes of various orders of magnitude. However, we point out that one recent proposal involving resonant LC circuits represents the best option in terms of individual merger detection prospects in the range $(1÷100) \, \text{MHz}$. In the same frequency range, we note that alternative setups involving resonant cavities, whose concept is currently under development, might represent a promising technology to detect individual merger events. We also show that a detection of the stochastic gravitational wave background produced by unresolved binaries is possible only if the theoretical sensitivity of the proposed Gaussian beam detector is achieved. Such a detector, whose feasibility is subject to various caveats, may be able to rule-out some scenarios for asteroidal mass primordial black hole dark matter. We conclude that pursuing dedicated studies and developments of gravitational wave detectors in the ultra-high-frequency band remains motivated and may lead to novel probes on the existence of light primordial black holes.

description: To improve the FAIRness of ever increasing amounts of complex biomedical data, validation of both the structure and the content of data is required. The ELIXIR biovalidator allows to verify syntactic and semantic compliance of JSON documents by extending the existing JSON Schema syntax.
 The ELIXIR biovalidator supports common life sciences use cases through five extended keywords to enable ontology, taxonomy and identifier validation.
 For example, to express that the JSON property disease_ontology_id can only have terms that are from the Phenotype and Trait Ontology (PATO) or Monarch Disease Ontology (MONDO), the keyword graphRestriction can be used with a parent term ID and an ontology ID to validate that content references a subclass of the disease classes PATO:0000461 or MONDO:0000001.
 The ELIXIR biovalidator is capable of running as a service or as a one-time script to validate a JSON document against a schema. The biovalidator is currently deployed in the data ingest system for the Human Cell Atlas Data Coordination Platform, European Genome-phenome Archive (EGA), and EMBL-EBI BioSamples. At EMBL-EBI BioSamples we have used the biovalidator to validate over 30 million samples using schemas such as MiXS and MIAPPE for genomic and plant metadata respectively.
 The poster presents capabilities of ELIXIR biovalidator and current successful use cases, focusing on new development and use cases since the original publication of the tool.

description: We study sequences of optimal walks of a growing length, in weighted digraphs, or equivalently, sequences of entries of max-algebraic matrix powers with growing exponents. It is known that these sequences are eventually periodic when the digraphs are strongly connected. The transient of such periodicity depends, in general, both on the size of digraph and on the magnitude of the weights. In this paper, we show that some bounds on the indices of periodicity of (unweighted) digraphs, such as the bounds of Wielandt, Dulmage-Mendelsohn, Schwarz, Kim and Gregory-Kirkland-Pullman, apply to the weights of optimal walks when one of their ends is a critical node.

description: In this paper, we provide efficient estimators and honest confidence bands for a variety of treatment effects including local average (LATE) and local quantile treatment effects (LQTE) in data-rich environments. We can handle very many control variables, endogenous receipt of treatment, heterogeneous treatment effects, and function-valued outcomes. Our framework covers the special case of exogenous receipt of treatment, either conditional on controls or unconditionally as in randomized control trials. In the latter case, our approach produces efficient estimators and honest bands for (functional) average treatment effects (ATE) and quantile treatment effects (QTE). To make informative inference possible, we assume that key reduced form predictive relationships are approximately sparse. This assumption allows the use of regularization and selection methods to estimate those relations, and we provide methods for post-regularization and post-selection inference that are uniformly valid (honest) across a wide-range of models. We show that a key ingredient enabling honest inference is the use of orthogonal or doubly robust moment conditions in estimating certain reduced form functional parameters. We illustrate the use of the proposed methods with an application to estimating the effect of 401(k) eligibility and participation on accumulated assets.

description: We study mesoscopic fluctuations in the supercurrent of a Josephson junction consisting of a topological insulator microbridge between two conventional superconductors. In the model, we account for the strong proximity effect when superconductors induce a gap in the spectrum of surface states as well as a magnetic field piercing the junction area that causes depairing and gap filling. The overall magnitude and functional form of the Josephson current fluctuations are determined analytically, and found to sensitively depend on the coupling strength to surface states, Thouless energy, and pair-breaking energy scales in the problem. We also study the density of states that can be measured by scanning probes. Technically, mesoscopic fluctuations on top of the mean field description of the proximity effect in the topological region are described by a field theory approach, the replica nonlinear $σ$-model in the class-D of the extended symmetry classification.

description: In the framework of a cosmological model of the Universe filled with a nonrelativistic particle soup, we easily reproduce inflation due to the quantum potential. The lightest particles in the soup serve as a driving force of this simple, natural and promising mechanism. It is explicitly demonstrated that the appropriate choice of their mass and fraction leads to reasonable numbers of e-folds. Thus, the direct introduction of the quantum potential into cosmology of the earliest Universe gives ample opportunities of successful reconsideration of the modern inflationary theory.

Subjects: Air pollution processes and air quality measurement

description: The issue of particulate matter (PM) and associated health and environmental problems has been subjected to extensive research in a number of countries. However, there are no recent studies concerning the physical and chemical properties of PM from urban Cardiff. Measurements were made to study particulate matter, their sources, chemical compositions, gaseous precursorsand their seasonal variations in urban Cardiff (latitude: 51° 28 ́ 59.47 ̈N and longitude: 03° 09 ́ 58.08 ̈W) from December 2009 to November 2010. A low volume air sampler for PM10and PM2.5particles, and real-time air samplers for TSP, PM10, PM2.5, PM1, NO, NO2, NOx, SO2and VOCs were used during sampling. The collected ambient air suspended particles were analysed for seven major ions (Cl−, NO3−, SO42−, Ca²⁺, Mg²⁺, K⁺and Na⁺) and 12 elements (Na, Mg, Al, K, Ca, Cr, Fe, Ni, Cu, Zn, Cd and Pb) by using an ion chromatography and atomic absorption spectrometer respectively.Cl⁻, SO42−and NO3−were generally the major ions in fractions of PM10and PM2.5, while the elements Na, Mg, Ca, Al, K, and Fe were the most abundant elements. A good correlation was observed between PM10and PM2.5 indicating that PM10and PM2.5 contribute significantly to PM levels in urban Cardiff.Most of the ions and elements in both PM fractions were abundant in the winter season. Natural sources were the highest contributors followed by anthropogenic sources for the analysed elements in PM10and PM2.5.Enrichment factor (EF) analysis showed the enrichment factor was higher in PM10and PM2.5elements such as Zn, Pb, Cu, Cr and Cd. The high enrichment factor of these elements in urban Cardiff suggested that the dominant sources for these elements were non-crustal. Real-time measurements of PM precursorgases did not exceed the standard concentrations given by the Air Quality Strategy (AQS) for these pollutants.
The effects of storage and processing on the properties of Arachis hypogeae (peanut).

Subjects: Crop and pasture post harvest technologies (incl. transportation and storage)

description: The project was part of a Knowledge Transfer Partnership between Sunscoop Products Ltd. and the University of Wales Institute, Cardiff. The processing parameters of (dry roasting) peanuts were mapped and improvements made, increasing product throughput and energy efficiency. A cross sample of peanuts were compared for their ash, moisture,lipid, protein and carbohydrate, only protein and carbohydrate showed significant differences. Free amino groups and reducing sugars were also compared, country of origin and size of peanut showed significant differences, and correlations were observed between development of colour during heat processing and reduction in the content of free amino groups and reducing sugars. High oleic peanuts (HOP) showed higher oxidative stability than conventional peanuts (CP) in both nibbed (<2mm3 pieces) and whole kernels. Temperature and processing format influenced the oxidative stability of both varieties, more than the addition of nitrogen to the packaging. Antioxidant assays correlated with the rate of lipid oxidation, where antioxidant levels decreased during storage and peroxide value increased. Rates of tocopherol oxidation followed those of previous reported data, except Î±-tocopherol levels increased in CP whole kernels during 7 weeks, no other increases were observed. The characterisation of oil bodies from two varieties of peanut, HOP and CP, showed small differences in the particle size of the oil bodies and zeta potential. Significant differences were observed between the protein contents, and SDS-PAGE showed higher concentrations of high molecular weight proteins in HOP oil bodies. CP showed higher amounts of Î±-tocopherols than HOP and CP showed higher concentrations of tocopherols in the oil bodies rather than the extracted oil. In vivo cross sections of peanuts indicated some body stability during processing.
An examination of mental toughness in competitive sport.
Creators: name: Connaughton, Declan
Publisher: name: Cardiff Metropolitan University

Subjects: Sport and exercise psychology

description: This thesis provided an in-depth examination of mental toughness in sports performers, and comprised three studies, of which Study 3 contained two parts. The aim of the thesis was to: define mental toughness, identify its component parts, devise a working framework of mental toughness, and identify the underlying mechanisms involved in the development and maintenance of mental toughness. Study 1 addressed the definition of mental toughness and its essential components using 10 international performers. The proposed definition emphasized both general and specific dimensions , and 12 attributes fundamental to the ideal mentally tough performer. These covered self-belief, desire/motivation, dealing with pressure and anxiety, focus (performance and lifestyle related), and pain/hardship factors. Study 2 built upon the findings of Study 1 in a sample of eight Olympic or World Champions, three coaches, and four sport psychologists. Findings verified the definition, and identified 30 attributes that were developed into a working framework of mental toughness. The 30 attributes were found to cluster into 13 subcomponents and four dimensions within an overall working framework: a general dimension (attitude/mindset), and three time-specific dimensions (training, competition, post-competition). Study 3 re-interviewed l1 of the participants from Study 2 regarding: (a) the development and maintenance of mental toughness, and (b) how the framework dimensions and subcomponents interacted during the development and maintenance process. Findings revealed four distinct career phases in the development and maintenance of mental toughness. Critical incidents, both positive and negative, were perceived to act as catalysts in cultivating mental toughness, and once acquired, mental toughness needed to be maintained. Findings also confirmed the development and subsequent maintenance of mental toughness over three stages. Factors affecting development and maintenance included: stage l, skill mastery and socialization; stage2, competitiveness, successes in training and competitions; and stage 3, international competitive experience, education, the use of mental skills, a wide ranging social support network, and reflective practice. This prolonged research program has resulted in an empirically based definition of mental toughness, the development of a framework depicting its component parts, and provided an in-depth understanding of the mechanisms involved in the development and maintenance of mental toughness. Practical implications indicate that mental toughness develops over three distinct stages, in the dimensional order of attitude/mindset, training, competition, and post-competition, and requires maintenance. Future directions are discussed in relation to measurement and intervention strategies.

On independence of iterated Whitehead doubles in the knot concordance group

description: Let $D(K)$ be the positively-clasped untwisted Whitehead double of a knot $K$, and $T_{p,q}$ be the $(p,q)$ torus knot. We show that $D(T_{2,2m+1})$ and $D^2(T_{2,2m+1})$ are linearly independent in the smooth knot concordance group $\mathcal{C}$ for each $m\geq 2$. Further, $D(T_{2,5})$ and $D^2(T_{2,5})$ generate a $\mathbb{Z}\oplus\mathbb{Z}$ summand in the subgroup of $\mathcal{C}$ generated by topologically slice knots. We use the concordance invariant $δ$ of Manolescu and Owens, using Heegaard Floer correction term. Interestingly, these results are not easily shown using other concordance invariants such as the $τ$-invariant of knot Floer theory and the $s$-invariant of Khovanov homology. We also determine the infinity version of the knot Floer complex of $D(T_{2,2m+1})$ for any $m\geq 1$ generalizing a result for $T_{2,3}$ of Hedden, Kim and Livingston.

description: Updated LHC data on the new 126 GeV boson during the 7 and 8 TeV runnings strengthen the standard model Higgs boson interpretation further. Through the global $χ^2$ analysis, we investigate whether the new particle could be one of the scalar particles in two Higgs doublet models. Four types (Type I, II, X and Y) are comprehensively studied. Taking the recent analysis on the spin-parity of the new boson, we consider two scenarios: the new boson is either the light CP-even one ($h^0$) or the heavy CP-even one ($H^0$). It is found that both scenarios are consistent with the new data, not only in the parameter regions near the decoupling limit but also in other regions far from the decoupling limit. In addition, the current data are compatible with the possibility that the light Higgs boson $h^0$ is hidden in the mass window of 90-100 GeV. The diphoton or $ττ$ channel can provide a probe of this possibility by the enhanced signal rates.

description: The infall of the Sagittarius (Sgr) Dwarf Spheroidal Galaxy in the Milky Way halo is an unique opportunity to understand how the different components of a dwarf galaxy could be tidally removed. In this work, we reconstruct the Sgr core morphology and kinematics on the basis of a model that has already successfully reproduced the Sgr stream. Here we use a very high resolution model that almost resolves individual stars in the Sgr core. It reproduces most of the observed morphology and kinematic properties, without specific fine-tuning. We also show that the dark matter may have been almost entirely stripped by Milky Way tides after two passages at pericenter. Finally the model predicts that the Sgr core will be fully disrupted within the next 2 Gyr.
