description: Electrical control of magnetism is a long-standing goal in physics and technology, recently developed electrolyte gating techniques providing a promising route to realization. Validating a recent theoretical prediction, here we demonstrate large enhancement of electrostatic modulation of ferromagnetic order in ion-gel-gated ultrathin La$_{0.5}$Sr$_{0.5}$CoO$_{3-δ}$ by thickness-tuning to the brink of a magnetic percolation transition. Application of only 3-4 V then drives a transition from a short-range-ordered insulator to a robust long-range ferromagnetic metal, realizing giant electrostatic Curie temperature modulation over a 150 K window. In operando polarized neutron reflectometry confirms gate-controlled ferromagnetism, also demonstrating unusually deep penetration of induced magnetization, in further agreement with theory.

description: We examine the Standard and the New Physics (NP) contributions to the ZZZ, ZZgamma and Zgammagamma neutral gauge couplings. At the one-loop level, if we assume that there is no CP violation contained in NP beyond the Standard Model one, we find that only CP conserving neutral gauge couplings are generated, either from the standard quarks and leptons, or from possible New Physics (NP) fermions. Bosonic one-loop diagrams never contribute to these couplings, while the aforementioned fermionic contributions satisfy hZ3=-fgamma5, hZ4=hgamma4=0. We also study examples of two-loop NP effects that could generate non vanishing h4 couplings. We compare quantitative estimates from SM, MSSM and some specific examples of NP contributions, and we discuss their observability at future colliders.

description: A (tandem) duplication of length $ k $ is an insertion of an exact copy of a substring of length $ k $ next to its original position. This and related types of impairments are of relevance in modeling communication in the presence of synchronization errors, as well as in several information storage applications. We demonstrate that Levenshtein's construction of binary codes correcting insertions of zeros is, with minor modifications, applicable also to channels with arbitrary alphabets and with duplication errors of arbitrary (but fixed) length $ k $. Furthermore, we derive bounds on the cardinality of optimal $ q $-ary codes correcting up to $ t $ duplications of length $ k $, and establish the following corollaries in the asymptotic regime of growing block-length: 1.) the presented family of codes is optimal for every $ q, t, k $, in the sense of the asymptotic scaling of code redundancy; 2.) the upper bound, when specialized to $ q = 2 $, $ k = 1 $, improves upon Levenshtein's bound for every $ t \geq 3 $; 3.) the bounds coincide for $ t = 1 $, thus yielding the exact asymptotic behavior of the size of optimal single-duplication-correcting codes.

Retoriche urbane al tempo della pandemia

description: The urban problems that the pandemic poses are not new problems, they have been the object of urban planning reflection since the founding of the discipline with the industrial revolution. The policies of growth and development have thus become an opportunity for the accumulation of wealth for small groups, while the negative effects on the environment as well as social inequalities have not been (and do not constitute) a source of concern. The time has come to question the ethics of doing and governing architecture and urban planning, Covid-19, like the current environmental crisis, does not require generic answers but precise field choices. The considerations in this text address several topics. First of all, the relationship between pandemic, environmental crisis and inequality. This problematic interweaving has repercussions on the organisation of cities and processes of urban “neo-colonialism” that fail to recognise the complexity of the urban phenomenon in the world. Finally, the association between the pandemic, the environmental crisis and the city, which presupposes urban visions and shared projects, but appears increasingly directed towards marketing strategies, to the detriment of governance practices.

description: We present a study of deep levels in CdZnTeSe radiation-detection materials. The approach relies on electrical methods that combine time and temperature evolution of the electric field and electric current after switching on the bias voltage. We also applied two optical methods to study the deep levels. The first method utilizes the temperature and temporal analysis of the electric-field evolution after switching off an additional light illuminating the sample at a wavelength of 940 nm. The second method involved measuring of the electric-field spectral dependence during near infrared illumination. We compare the results with those obtained with high-quality CdZnTe detector-grade material. We conclude that the introduction of Se into the lattice leads to a shift of the second ionization level of the Cd vacancy towards the conduction band, as predicted recently by first-principles calculations based on screened hybrid functionals.

description: Connected health is a technology that associates medical devices, security devices and communication technologies. It enables patients to be monitored and treated remotely from their home. Patients' data and medical records within a connected health system should be securely stored and transmitted for further analysis and diagnosis. This paper presents a set of security solutions that can be deployed in a connected health environment, which includes the advanced encryption standard (AES) algorithm and electrocardiogram (ECG) identification system. Efficient System-on-Chip (SoC) implementations for the proposed algorithms have been carried out on the Xilinx ZC702 prototyping board. The Achieved hardware implementation results have shown that the proposed AES and ECG identification based system met the real-time requirements and outperformed existing field programmable gate array (FPGA)-based systems in different key performance metrics such as processing time, hardware resources and power consumption. The proposed systems can process an ECG sample in 10.71 ms and uses only 30% of the available hardware resources with a power consumption of 107 mW.

The Fe magnetism is suppressed due to both pressures and no magnetic order was observed above a P-substitution level of 40% or 5.2 GPa hydrostatic pressure. We compared both pressures and found that the isovalent As by P substitution change the crystallographic and electronic properties differently than hydrostatic pressure.

Né vicino, né distante.

description: In the first phase of the COVID-19 pandemic, the scientific community has tried to place itself in a “post-pandemic” perspective, seeking the “new at all costs”. But it is difficult reasoning in a “post-Covid” key, both due to the obvious contradiction of doing so while the health crisis was still ongoing, and because the critical distance from the present had not yet matured. Faced with the effort of the project sciences to demonstrate the ability to ‘project’, that is, to be able to manage prospects for the future, this reflection intends to formulate -at the same time-critical and proactive reasoning that starts from the extraordinary experience underway to reconstruct the conditions of the public space. The health issue has heavily invested the public space, which in turn has become problematic, strongly requiring elements of innovation from the project to guarantee safety in the situations of presence, reinventing the conditions of proximity, directing action to define new geometric and proxemics logics. In the direction to find different questions from the one that asks “what is the good distance from the other?”, the author thinks it is good to start a reflection about the new way experienced during the pandemic, finally finding the conditions in which we can stay together again.

description: Stellar rotation periods are valuable both for constraining models of angular momentum loss and for under- standing how magnetic features impact inferences of exoplanet parameters. Building on our previous work in the northern hemisphere, we have used long-term, ground-based photometric monitoring from the MEarth Observatory to measure 234 rotation periods for nearby, southern hemisphere M dwarfs. Notable examples include the exoplanet hosts GJ 1132, LHS 1140, and Proxima Centauri. We find excellent agreement between our data and K2 photometry for the overlapping subset. Amongst the sample of stars with the highest quality datasets, we recover periods in 66%; as the length of the dataset increases, our recovery rate approaches 100%. The longest rotation periods we detect are around 140 days, which we suggest represent the periods that are reached when M dwarfs are as old as the local thick disk (about 9 Gyr).

description: The next-to-leading order contribution $\d¶\omn (ø,\vc q )$ to the polarization function of the hot gluon system is analysed at non-zero wave vectors $\vc q \,$. Using Braaten-Pisarski resummation and general covariant gauges, $\d¶\omn$ is found to be gauge-fixing independent and transverse on the longitudinal mass-shell. The real part of the longitudinal component $\d¶_\ell$ is UV and IR stable (for real $q$). At imaginary $q$ it is IR singular, and at the point $ø=0$, $q^2=-3m^2$ it coincides with the result of Rebhan for next-to-leading order Debye screening. When $q$ approaches the lightcone, $\d¶_\ell $ diverges like $1 / \wu {ø^2 - q^2} $, reflecting the breakdown of the Braaten-Pisarski decomposition scheme in this limit.

An HI selected sample of galaxies - The HI mass function and the surface brightness distribution

description: Results from the Arecibo HI Strip Survey, an unbiased extragalactic HI survey, combined with optical and 21cm follow-up observations, determine the HI Mass Function and the cosmological mass density of HI at the present epoch. Both are consistent with earlier estimates, computed for the population of optically selected galaxies. This consistency occurs because, although the distribution of optical central surface brightnesses among galaxies is flat, we fail to find a population of galaxies with central surface brightnesses fainter than 24 B-mag/arcsec^2, even though there is no observational selection against them.

Yet Another Model of Gamma-Ray Bursts
Creators: name: Katz, J. I.
Publisher: name: arXiv
Year: 1997
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Sari and Piran have demonstrated that the time structure of gamma-ray bursts must reflect the time structure of their energy release. A model which satisfies this condition uses the electrodynamic emission of energy by the magnetized rotating ring of dense matter left by neutron star coalescence; GRB are essentially fast, high field, differentially rotating pulsars. The energy densities are large enough that the power appears as an outflowing equilibrium pair plasma, which produces the burst by baryon entrainment and subsequent internal shocks. I estimate the magnetic field and characteristic time scale for its rearrangement, which determines the observed time structure of the burst. There may be quasi-periodic oscillations at the rotational frequencies, which are predicted to range up to 5770 Hz (in a local frame). This model is one of a general class of electrodynamic accretion models which includes the Blandford and Lovelace model of AGN, and which can also be applied to black hole X-ray sources of stellar mass. The apparent efficiency of nonthermal particle acceleration is predicted to be 10--50%, but higher values are possible if the underlying accretion flow is super-Eddington. Applications to high energy gamma-ray observations of AGN are briefly discussed.

description: We present ALMA Band 9 observations of the [C II]158um emission for a sample of 10 main-sequence galaxies at redshift z ~ 2, with typical stellar masses (log M*/Msun ~ 10.0 - 10.9) and star formation rates (~ 35 - 115 Msun/yr). Given the strong and well understood evolution of the interstellar medium from the present to z = 2, we investigate the behaviour of the [C II] emission and empirically identify its primary driver. We detect [C II] from six galaxies (four secure, two tentative) and estimate ensemble averages including non detections. The [C II]-to-infrared luminosity ratio (L[C II]/LIR) of our sample is similar to that of local main-sequence galaxies (~ 2 x 10^-3), and ~ 10 times higher than that of starbursts. The [C II] emission has an average spatial extent of 4 - 7 kpc, consistent with the optical size. Complementing our sample with literature data, we find that the [C II] luminosity correlates with galaxies' molecular gas mass, with a mean absolute deviation of 0.2 dex and without evident systematics: the [C II]-to-H2 conversion factor (alpha_[C II] ~ 30 Msun/Lsun) is largely independent of galaxies' depletion time, metallicity, and redshift. [C II] seems therefore a convenient tracer to estimate galaxies' molecular gas content regardless of their starburst or main-sequence nature, and extending to metal-poor galaxies at low and high redshifts. The dearth of [C II] emission reported for z > 6 - 7 galaxies might suggest either a high star formation efficiency or a small fraction of UV light from star formation reprocessed by dust.

description: A heterochromatic (or rainbow) graph is an edge-colored graph whose edges have distinct colors, that is, where each color appears at most once. In this paper, I propose a $(g,f)$-chromatic graph as an edge-colored graph where each color $c$ appears at least $g(c)$ times and at most $f(c)$ times. I also present a necessary and sufficient condition for edge-colored graphs (not necessary to be proper) to have a $(g,f)$-chromatic spanning tree. Using this criterion, I show that an edge-colored complete graph $G$ has a spanning tree with a color probability distribution `similar' to that of $G$. Moreover, I conjecture that an edge-colored complete graph $G$ of order $2n$ $(n \ge 3)$ can be partitioned into $n$ edge-disjoint spanning trees such that each has a color probability distribution `similar' to that of $G$.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: The global COVID-19 pandemic threatens much of the theory of human proxemics, and raises fundamental questions about human evolution and contemporary life. If we evolved in close contact with each other for thousands of years, does “social distance” contradict this fact? In today’s world, what should be local and what should be global? How much human suffering and death should be tolerated to “save the economy”? These and other questions are examined in this essay.

description: It has been suggested that associations of high-redshift dusty star-forming galaxies (DSFGs) may serve as beacons of protoclusters because DSFGs are high-mass galaxies undergoing rapid assembly. We investigate this possibility using the Bolshoi cosmological N-body simulation and a model for populating the simulation with DSFGs. We find that DSFGs are incomplete tracers of protoclusters because of stochastic sampling effects, and at redshift <~ 2.5, because of ‘downsizing’, the highest dark matter overdensities are not well traced by DSFG associations. However, at high redshift, bright submm sources provide effective means for finding some of the most extreme dark matter overdensities in the Universe; I will discuss two such examples discovered with the South Pole Telescope.
Oltre la pandemia. Ripensare territori e città per una civiltà della cura

description: History sometimes presents unexpected crossroads that, under the surface of an apparent contingency, are the result of long-lasting processes that suddenly take shape, marking a watershed line. The COVID-19 outbreak and its consequences really seem to represent one of these events. Relating to that the debate involved not only the domain of spatial planning but also the ways of reading and interpreting the relationships between cities and territories and underlying development models. It is certainly a propitious moment to solicit necessary, open, and transversal reflections, both on a thematic and disciplinary level, at a time when urgency makes us perhaps more sensitive, free and creative in grasping with dramatic contradictions as compelling challenges for the future. The contributions collected by this special issue of CONTESTI draw a polychrome map of reflections, born from the urgency to read, understand and interpret the historical moment we are experiencing but also to go "beyond the pandemic", not only in a temporal sense, but in relation to challenges that it poses to cities and territories and to the discipline of spatial planning and urban design.

On `orbital' and `spin' angular momentum of light in classical and quantum theories -- a general framework

Year: 2018

description: We develop a general framework to analyze the two important and much discussed questions concerning (a) `orbital' and `spin' angular momentum carried by light and (b) the paraxial approximation of the free Maxwell system both in the classical as well as quantum domains. After formulating the classical free Maxwell system in the transverse gauge in terms of complex analytical signals we derive expressions for the constants of motion associated with its Poincaré symmetry. In particular, we show that the constant of motion corresponding to the total angular momentum ${\bf J}$ naturally splits into an `orbital' part ${\bf L}$ and a `spin' part ${\bf S}$ each of which is a constant of motion in its own right. We then proceed to discuss quantization of the free Maxwell system and construct the operators generating the Poincaré group in the quantum context and analyze their algebraic properties and find that while the quantum counterparts $\hat{\bf L}$ and $\hat{\bf S}$ of ${\bf L}$ and ${\bf S}$ go over into bona fide observables, they fail to satisfy the angular momentum algebra precluding the possibility of their interpretation as `orbital' and `spin' operators at the classical level. On the other hand $\hat{\bf J}=\hat{\bf L}+ \hat{\bf S}$ does satisfy the angular momentum algebra and together with $\hat{\bf S}$ generates the group $E(3)$. We then present an analysis of single photon states, paraxial quantization both in the scalar as well as vector cases, single photon states in the paraxial regime. All along a close connection is maintained with the Hilbert space $\mathcal{M}$ that arises in the classical context thereby providing a bridge between classical and quantum descriptions of radiation fields.

A GLOBAL QCD STUDY OF DIRECT PHOTON PRODUCTION

description: A global QCD analysis of the direct photon production process from both fixed target and collider experiments is presented. These data sets now completely cover the parton $x$ range from 0.01 to 0.6, thereby providing a stringent test of perturbative QCD and parton distributions. Previous detailed studies of direct photons emphasized fixed target data. We find most data sets have a steeper $p_t$ distribution than the QCD prediction. Neither global fits with new parton distributions nor improved photon fragmentation functions can resolve this problem since the deviation occurs at different $x$ values for experiments at different energies. A more likely explanation is the need for additional broadening of the $k_t$ of the initial state partons. The magnitude and the possible physical origin of this effect are investigated and discussed.

description: We obtain three and four dimensional conformal field theories with less than maximal supersymmetry by using their supergravity duals. These supergravity theories are type II on $AdS_5 \times CP^2$, IIA on $AdS_4 \times CP^3$, IIB on $AdS_5 \times S^5/Z_k$ and D=11 supergravity on $AdS_4 \times S^7/Z_k$. They are obtained from the spherically compactified ten and eleven dimensional theories by either Hopf reduction or by winding the U(1) fiber over the base.

Temperature Dependence of the Vacancy Formation Energy in Solid $^4$He

description: We studied the thermal effects on the behavior of incommensurate solid $^4$He at low temperatures using the path integral Monte Carlo method. Below a certain temperature, depending on the density and the structure of the crystal, the vacancies delocalize and a finite condensate fraction appears. We calculated the vacancy formation energy as a function of the temperature and observed a behavior compatible with a two-step structure, with a gap of few K appearing at the onset temperature of off-diagonal long-range order. Estimation of the energy cost of creating two vacancies seems to indicate an effective attractive interaction among the vacancies but the large error inherent to its numerical estimation precludes a definitive statement.

Calibrating Codes Safety Factors for Different Life Cycles - Proposed Simplified Procedure
Creators: name: Shamir, Eliezer
Publisher: name: Zenodo
Year: 2021
Subjects: Life cycle
code calibration

safety factors
target reliability factor

description: In light of a 120-year life cycle, a simpler method for calibrating code safety factors was used in the updating of the upgraded Israeli Code specifications for aseismic construction of bridges. Structures are often assumed to be planned for a 50-year life cycle, whereas unique or critical infrastructure facilities should be designed for longer life cycles. Aside from issues of reliability and maintenance, this also entails the need to cover the risk of exceeding characteristic design live loads for a prolonged period while maintaining the same standards of agreed risk assumed by various codes as good enough for the typical 50-year life cycle. Given that these structures are designed using design methods, formulations, material characteristic strengths, and partial safety factors in accordance with existing codes, scaling of partial safety factors, or alternatively an additional "compensating" factor, is needed. This proposed simplified procedure to arrive at a reasonable calibration of code safety factors, based upon structural reliability considerations, is presented.

Estimating Omega from Galaxy Redshifts: Linear Flow Distortions and Nonlinear Clustering

description: We propose a method to determine the cosmic mass density Omega from redshift-space distortions induced by large-scale flows in the presence of nonlinear clustering. Nonlinear structures in redshift space such as fingers of God can contaminate distortions from linear flows on scales as large as several times the small-scale pairwise velocity dispersion sigma_v. Following Peacock & Dodds (1994), we work in the Fourier domain and propose a model to describe the anisotropy in the redshift-space power spectrum; tests with high-resolution numerical data demonstrate that the model is robust for both mass and biased galaxy halos on translinear scales and above. On the basis of this model, we propose an estimator of the linear growth parameter beta = Omega^0.6/b, where b measures bias, derived from sampling functions which are tuned to eliminate distortions from nonlinear clustering. The measure is tested on the numerical data and found to recover the true value of beta to within ~10%. An analysis of the IRAS 1.2Jy galaxies yields beta = 0.8+0.4/-0.3 at a scale of 1,000 km/s which is close to optimal given the shot noise and the finite survey volume. This measurement is consistent with dynamical estimates of beta derived from both real-space and redshift-space information. The importance of the method presented here is that nonlinear clustering effects are removed to enable linear correlation anisotropy measurements on scales approaching the translinear regime. We discuss implications for analyses of forthcoming optical redshift surveys in which the dispersion is more than a factor of two greater than in the IRAS data.

description: We analyse the stability of global O(3) monopoles in the infinite cut-off (or scalar mass) limit. We obtain the perturbation equations and prove that the spherically symmetric solution is classically stable (or neutrally stable) to axially symmetric square integrable or power-law decay perturbations. Moreover we show that, in spite of the existence of a conserved topological charge, the energy barrier between the monopole and the vacuum is finite even in the limit where the cut-off is taken to infinity. This feature is specific of global monopoles and independent of the details of the scalar potential.
