description: Superconducting nanowire single photon detectors (SNSPDs) offer high-quantum-efficiency and low-dark-count-rate single photon detection. In a growing number of cases, large magnetic fields are being incorporated into quantum microscopes, nanophotonic devices, and sensors for nuclear and high-energy physics that rely on SNSPDs, but superconducting devices generally operate poorly in large magnetic fields. Here, we demonstrate robust performance of amorphous SNSPDs in magnetic fields of up to $\pm 6$ T with a negligible dark count rate and unchanged quantum efficiency at typical bias currents. Critically, we also show that in the electrothermal oscillation regime, the SNSPD can be used as a magnetometer with sensitivity of better than 100 $\mathrm{μT/\sqrt{Hz}}$ and as a thermometer with sensitivity of 20 $\mathrm{μK/\sqrt{Hz}}$ at 1 K. Thus, a single photon detector integrated into a quantum device can be used as a multifunctional quantum sensor capable of describing the temperature and magnetic field on-chip simply by varying the bias current to change the operating modality from single photon detection to thermometry or magnetometry.

description: (Abridged) I report new light curves and determine the rotations and phase functions of several large Kuiper Belt objects, including the dwarf planet Eris (2003 UB313). (120348) 2004 TY364 shows a light curve which if double-peaked has a period of 11.70+-0.01 hours and peak-to-peak amplitude of 0.22+-0.02 magnitudes. (84922) 2003 VS2 has a well defined double-peaked light curve of 7.41+-0.02 hours with a 0.21+-0.02 magnitude range. (126154) 2001 YH140 shows variability of 0.21+-0.04 magnitudes with a possible 13.25+-0.2 hour single-peaked period. The seven new KBOs in the sample which show no discernible variations within the uncertainties on short rotational time scales are 2001 UQ18, (55565) 2002 AW197, (119979) 2002 WC19, (120132) 2003 FY128, (136108) Eris 2003 UB313, (90482) Orcus 2004 DW, and (90568) 2004 GV9. The three medium to large sized Kuiper Belt objects 2004 TY364, Orcus and 2004 GV9 show fairly steep linear phase curves (~0.18 to 0.26 mags per degree) between phase angles of 0.1 and 1.5 degrees. The extremely large dwarf planet Eris (2003 UB313) shows a shallower phase curve (0.09+-0.03 mags per degree) which is more similar to the other known dwarf planet Pluto. It appears the surface properties of the largest dwarf planets in the Kuiper Belt maybe different than the smaller Kuiper Belt objects. This may have to do with the larger objects ability to hold more volatile ices as well as sustain atmospheres. The absolute magnitudes obtained using the measured phase slopes are a few tenths of magnitudes different from those given by the MPC.

description: The occurrence of pair-instability supernovae is predicted to prevent the formation of black holes with masses $\gtrsim 50 M_\odot$. Recent gravitational-wave detections in this mass range require an explanation beyond that of standard stellar collapse. Current modeling strategies include the hierarchical assembly of previous generations of black-hole mergers as well as other mechanisms of astrophysical nature (lowered nuclear-reaction rates, envelope retention, stellar mergers, accretion, dredge-up episodes). In this paper, we point out the occurrence of an exclusion region that cannot be easily populated by hierarchical black-hole mergers. A future gravitational-wave detection of a black hole with mass $\gtrsim 50M_\odot$ and spin $\lesssim 0.2$ will indicate that the pair-instability mass gap is polluted in some other way. Such a putative outlier can be explained using hierarchical mergers only with considerable fine-tuning of both mass ratio and spins of the preceding black-hole merger -- an assumption that can then be cross-checked against the bulk of the gravitational-wave catalog.

description: The threshold network model is a type of finite random graphs. In this paper, we introduce a generalized threshold network model. A pair of vertices with random weights is connected by an edge when real-valued functions of the pair of weights belong to given Borel sets. We extend several known limit theorems for the number of prescribed subgraphs to show that the strong law of large numbers can be uniform convergence. We also prove two limit theorems for the local and global clustering coefficients.

description: The influence of an external static magnetic field (up to 480 mT)on the structural properties of EuTiO$_3$ (ETO) polycrystalline samples was examined by powder XRD at the Elettra synchrotron facilities in the temperature range 100-300K. While the cubic to tetragonal structural phase transition temperature in this magnetic field range remains almost unaffected, significant lattice effects appear at two characteristic temperatures (~200K and 250K), which becomes more pronounced at a critical threshold magnetic field. At ~200K a change in the sign of the magnetostriction is detected attributed to a modification of the local magnetic properties from intrinsic ferromagnetism to intrinsic antiferromagnetism. These data are a clear indication that strong spin-lattice interactions govern also the high temperature phase of ETO and trigger the appearance of magnetic domain formation and novel phase transitions

description: When Fischler and Susskind proposed a holographic prescription based on the Particle Horizon, they found that spatially closed cosmological models do not verify it due to the apparently unavoidable recontraction of the Particle Horizon area. In this article, after a short review of their original work, we expose graphically and analytically that spatially closed cosmological models can avoid this problem if they expand fast enough. It has been also shown that the Holographic Principle is saturated for a codimension one brane dominated Universe. The Fischler-Susskind prescription is used to obtain the maximum number of degrees of freedom per Planck volume at the Planck era compatible with the Holographic Principle.

description: We demonstrate the formation of stable spatially-ordered states in a {\it uniform} and also {\it trapped} quasi-two-dimensional (quasi-2D) Rashba or Dresselhaus spin-orbit (SO) coupled pseudo spin-1/2 Bose-Einstein condensate using the mean-field Gross-Pitaevskii equation. For weak SO coupling, one can have a circularly-symmetric $(0,+1)$- or $(0,-1)$-type multi-ring state with intrinsic vorticity, for Rashba or Dresselhaus SO coupling, respectively, where the numbers in the parentheses denote the net angular momentum projection in the two components, in addition to a circularly-asymmetric degenerate state with zero net angular momentum projection. For intermediate SO couplings, in addition to the above two types, one can also have states with stripe pattern in component densities with no periodic modulation in total density. The stripe state continues to exist for large SO coupling. In addition, a new spatially-periodic state appears in the uniform system: a superlattice state, possessing some properties of a supersolid, with a square-lattice pattern in component densities and also in total density. In a trapped system the superlattice state is slightly different with multi-ring pattern in component density and a square-lattice pattern in total density. For an equal mixture of Rashba and Dresselhaus SO couplings, in both uniform and trapped systems, only stripe states are found for all strengths of SO couplings. In a uniform system all these states are quasi-2D solitonic states.

description: The concept of the scalar graviton as the source of the dark matter and dark energy of the gravitaional origin is applied to study the evolution of the isotropic homogeneous Universe. A realistic self-consistent solution to the modified pure gravity equations, which correctly describes the accelerated expansion of the spatially flat Universe, is found and investigated. It is argued that the scenario with the scalar gravitons filling up the Universe may emulate the LCDM model, reducing thus the true dark matter to an artefact.

The information and views set out in this report are those of the author(s) and do not necessarily reflect the official opinion of the European Union. Neither the European Union institutions and bodies nor any person acting on their behalf may be held responsible for the use which may be made of the information contained therein. ___ The CoAct (Co-designing Citizen Social Science for Collective Action) project proposes to face social global issues by placing citizens in a vulnerable situation at the centre of the research. This approach represents a new understanding of Citizen Social Science (CSS), as participatory research co-designed with citizen groups sharing a social concern. One of the social issues targeted is Mental Health Care (R&I Action #1, WP3) and this report corresponds to Deliverable D3.1 Report on Knowledge Coalition building. The research background of this R&I Action has been constructed based of the different but complementary experiences of the two main CoAct partners involved. While the OpenSystems research group (Universitat de Barcelona) has built a research methodology based on Citizen Social Science and citizen’s participation, Federació Salut Mental Catalunya has decades of experience in community mental health care activism and cooperative projects, situating the individuals withan experience of mental health and their families at the centre of this process. Based on these complementary experiences, the research has been oriented to mental health social support networks, referring to people's social environment, which is generated informally, not professionally. The report describes the different step of the Knowledge Coalition building, formed by representatives of public administrations, civil society organisations and co-researchers, acting in representation of their institutions. After a detailed mapping of the local, national and international institutions, a comprehensive engagement process was built, that resulted in the participation of 65 individuals representing 50 institutions and the realization of a total of 6 meetings, that were conducted online due to COVID-19 pandemic. During this process, the sharing of experiences and perspectives allowed to build a rich and detailed knowledge map concerning the current situation of the mental health social support networks and of the possible future actions needed. This knowledge map will be used in the next step of the research process: the research co-creation sessions involving individuals with an experience of mental health and their families as Co-Researchers.
Active Visual SLAM with Independently Rotating Camera

description: In active Visual-SLAM (V-SLAM), a robot relies on the information retrieved by its cameras to control its own movements for autonomous mapping of the environment. Cameras are usually statically linked to the robot's body, limiting the extra degrees of freedom for visual information acquisition. In this work, we overcome the aforementioned problem by introducing and leveraging an independently rotating camera on the robot base. This enables us to continuously control the heading of the camera, obtaining the desired optimal orientation for active V-SLAM, without rotating the robot itself. However, this additional degree of freedom introduces additional estimation uncertainties, which need to be accounted for. We do this by extending our robot's state estimate to include the camera state and jointly estimate the uncertainties. We develop our method based on a state-of-the-art active V-SLAM approach for omnidirectional robots and evaluate it through rigorous simulation and real robot experiments. We obtain more accurate maps, with lower energy consumption, while maintaining the benefits of the active approach with respect to the baseline. We also demonstrate how our method easily generalizes to other non-omnidirectional robotic platforms, which was a limitation of the previous approach. Code and implementation details are provided as open-source.

description: Currently, there is still a need to improve the contiguity of the rainbow trout reference genome and to use multiple genetic backgrounds that will represent the genetic diversity of this species. The Arlee doubled haploid line was originated from a domesticated hatchery strain that was originally collected from the northern California coast. The Canu pipeline was used to generate the Arlee line genome de-novo assembly from high coverage PacBio long-reads sequence data. The assembly was further improved with Bionano optical maps and Hi-C proximity ligation sequence data to generate 32 major scaffolds corresponding to the karyotype of the Arlee line (2N=64). It is composed of 938 scaffolds with N50 of 39.16 Mb and a total length of 2.33 Gb, of which ~95% was in 32 chromosome sequences with only 438 gaps between contigs and scaffolds. In rainbow trout the haploid chromosome number can vary from 29 to 32. In the Arlee karyotype the haploid chromosome number is 32 because chromosomes Omy04, 14 and 25 are divided into six acrocentric chromosomes. Additional structural variations that were identified in the Arlee genome included the major inversions on chromosomes Omy05 and Omy20 and additional 15 smaller inversions that will require further validation. This is also the first rainbow trout genome assembly that includes a scaffold with the sex-determination gene (sdY) in the chromosome Y sequence. The utility of this genome assembly is demonstrated through the improved annotation of the duplicated genome loci that harbor the IGH genes on chromosomes Omy12 and Omy13.

description: Despite many of the most common chaotic dynamical systems being continuous in time, it is through discrete time mappings that much of the understanding of chaos is formed. Henri Poincaré first made this connection by tracking consecutive iterations of the continuous flow with a lower-dimensional, transverse subspace. The mapping that iterates the dynamics through consecutive intersections of the flow with the subspace is now referred to as a Poincaré map, and it is the primary method available for interpreting and classifying chaotic dynamics. Unfortunately, in all but the simplest systems, an explicit form for such a mapping remains outstanding. This work proposes a method for obtaining explicit Poincaré mappings by using deep learning to construct an invertible coordinate transformation into a conjugate representation where the dynamics are governed by a relatively simple chaotic mapping. The invertible change of variable is based on an autoencoder, which allows for dimensionality reduction, and has the advantage of classifying chaotic systems using the equivalence relation of topological conjugacies. Indeed, the enforcement of topological conjugacies is the critical neural network regularization for learning the coordinate and dynamics pairing. We provide expository applications of the method to low-dimensional systems such as the Rössler and Lorenz systems, while also demonstrating the utility of the method on infinite-dimensional systems, such as the Kuramoto--Sivashinsky equation.

description: Parity doubling in excited hadrons is reviewed. Parity degeneracy in hadrons was first experimentally observed 40 years ago. Recently new experimental data on light mesons caused much excitement and renewed interest to the phenomenon, which still remains to be enigmatic. The present retrospective review is an attempt to trace the history of parity doubling phenomenon, thus providing a kind of introduction to the subject. We begin with early approaches of 1960s (Regge theory and dynamical symmetries) and end up with the latest trends (manifestations of broader degeneracies and AdS/QCD). We show the evolution of various ideas about parity doubling. The experimental evidence for this phenomenon is scrutinized in the non-strange sector. Some experiments of 1960s devoted to the search for missing non-strange bosons are re-examined and it is argued that results of these experiments are encouraging from the modern perspective.

description: In the framework of time-dependent density functional theory (TDDFT), the exact exchange-correlation (xc) kernel $f_{xc}(n,q,ω)$ determines the ground-state energy, excited-state energies, lifetimes, and the time-dependent linear density response of any many-electron system. The recently developed MCP07 xc kernel $f_{xc}(n,q,ω)$ of A. Ruzsinszky et al. [Phys. Rev. B 101, 245135 (2020)] yields excellent uniform electron gas (UEG) ground-state energies and plausible plasmon lifetimes. As MCP07 is constructed to describe $f_{xc}$ of the UEG, it cannot capture optical properties of real materials. To verify this claim, we follow Nazarov et al. [Phys. Rev. Lett. 102, 113001 (2009)] to construct the long-range, dynamic xc kernel, $\lim_{q\to 0}f_{xc}(n,q,ω) = -α(ω)e^2/q^2$, of a weakly inhomogeneous electron gas, using MCP07 and other common xc kernels. The strong wavevector and frequency dependence of the "ultranonlocality" coefficient $α(ω)$ is demonstrated for a variety of simple metals and semiconductors. We examine how imposing exact constraints on an approximate kernel shapes $α(ω)$. Comparisons to kernels derived from correlated-wavefunction calculations are drawn.

description: Based on the color-spin interaction in diquarks, we argue that charmed multiquark hadrons are likely to exist. Because of the appreciable number of charm quarks produced in central nucleus-nucleus collisions at ultrarelativistic energies, production of charmed multiquark hadrons is expected to be enhanced in these collisions. Using both the quark coalescence model and the statistical hadronization model, we estimate the yield of charmed tetraquark meson $T_{cc}$ and pentaquark baryon $Θ_{cs}$ in heavy ion collisions at RHIC and LHC. We further discuss the decay modes of these charmed exotic hadrons in order to facilitate their detections in experiments.
Intraspecific variation in the IUFRO 16 year old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) : Provenance-progeny trial in Haney, British Columbia
Creators: name: Kantarl, Mustafa
Publisher: name: University of British Columbia
Year: 2010

description: Variation in height, dbh and volume was analyzed after 16 years of growth. Results were compared with the 4th and 7th growing season measurements for height. This trial comprised 464 open-pollinated families representing 58 provenances planted at the University of British Columbia Research Forest in Haney, B.C. in 1971. Phenotypic variations between and within provenances, additive genetic variances, heritabilities, genetic gain and juvenile * mature correlations were estimated for the three growth variables according to zone groupings. The effects of provenance by block and family by block interactions were evaluated. Expected reductions from the genetic gain caused by the interactions were calculated. Relationships among growth variables and growth variables versus geographical variables were investigated by simple and multiple linear regression analyses. An attempt was made to classify provenances according to their adaptation to the Haney planting site, on the basis of their performance over the years. Within provenance variation for height was compared among provenances and was related to the geography of origin of provenances. Explanations from the point of evolutionary biology were discussed. High values of calculated genetic gain indicated that significant improvement could be achieved by selection. Age - to - age correlations for height were highly significant (p ≤ 0.01) over time and therefore it was concluded that selection is possible after age 7. However, if we consider the importance of the time factor in improvement, programs, it is feasible to select after age 5. Differential results obtained by regression analysis between height and dbh according to zone grouping suggest that volume will be a better criterion for selection purposes than height alone.

description: Ce mémoire est une étude compréhensive qui se penche sur la trajectoire singulière de quatre adultes, ayant suivi un parcours scolaire dans l’enseignement spécialisé durant leur enfance, et sur la façon dont ils s’auto-déterminent. Comment ont-il vécu cette orientation? Qu’en ont-ils retiré? Quelle séquelles en gardent-ils de nombreuses années plus tard? Ces quatre personnes nous livrent leur réalité d’élèves en difficulté et retracent leurs parcours par le biais d’entretiens qui mettent en lumière leurs trajectoires scolaires particulières, de leurs origines à leurs conclusions. Elles nous offrent une immersion dans leur vie d’élèves en difficulté, à travers leur propre regard. Cette recherche s’intéresse donc à la dimension sociale que revêt une orientation dans des filières mal perçues par la société, et pose la question de l’impact des stéréotypes, préjugés et parfois discriminations, dont sont victimes les individus qui n’entrent pas dans le cadre des normes de l’école publique ordinaire. Elle invite ainsi à se questionner, d’une part sur le traitement des enfants en difficulté, dans un contexte ordinaire; et d’autre part, sur les prises en charge proposées à ces élèves et sur les multiples conséquences d’une orientation en classe spécialisée. Elle interroge le sens de l’inclusion scolaire, au sens officiel du terme, et rend paradoxalement compte de l’exclusion à laquelle celle-ci condamne certains enfants qui ne parviennent pas à s’intégrer et à se fondre dans ledit contexte ordinaire.

description: The Fermilab Muon $g-2$ collaboration recently announced the first result of measurement of the muon anomalous magnetic moment ($g-2$), which confirmed the previous result at the Brookhaven National Laboratory and thus the discrepancy with its Standard Model prediction. We revisit low-scale supersymmetric models that are naturally capable to solve the muon $g-2$ anomaly, focusing on two distinct scenarios: chargino-contribution dominated and pure-bino-contribution dominated scenarios. It is shown that the slepton pair-production searches have excluded broad parameter spaces for both two scenarios, but they are not closed yet. For the chargino-dominated scenario, the models with $m_{\tildeμ_{\rm L}}\gtrsim m_{\tildeχ^{\pm}_1}$ are still widely allowed. For the bino-dominated scenario, we find that, although slightly non-trivial, the region with low $\tan β$ with heavy higgsinos is preferred. In the case of universal slepton masses, the low mass regions with $m_{\tildeμ}\lesssim 230$ GeV can explain the $g-2$ anomaly while satisfying the LHC constraints. Furthermore, we checked that the stau-bino coannihilation works properly to realize the bino thermal relic dark matter. We also investigate heavy staus case for the bino-dominated scenario, where the parameter region that can explain the muon $g-2$ anomaly is stretched to $m_{\tildeμ}\lesssim 1.3$ TeV.

description: High-resolution spectroscopy of U Gem was obtained during quiescence. We did not find a hot spot or gas stream around the outer boundaries of the accretion disk. Instead, we detected a strong narrow emission near the location of the secondary star. We measured the radial velocity curve from the wings of the double-peaked H$α$ emission line, and obtained a semi-amplitude value that is in excellent agreement with the obtained from observations in the ultraviolet spectral region by Sion et al. (1998). We present also a new method to obtain K_2, which enhances the detection of absorption or emission features arising in the late-type companion. Our results are compared with published values derived from the near-infrared NaI line doublet. From a comparison of the TiO band with those of late type M stars, we find that a best fit is obtained for a M6V star, contributing 5 percent of the total light at that spectral region. Assuming that the radial velocity semi-amplitudes reflect accurately the motion of the binary components, then from our results: K_em = 107+/-2 km/s; K_abs = 310+/-5 km/s, and using the inclination angle given by Zhang & Robinson(1987); i = 69.7+/-0.7, the system parameters become: M_WD = 1.20+/-0.05 M_sun,; M_RD = 0.42+/-0.04 M_sun; and a = 1.55+/- 0.02 R_sun. Based on the separation of the double emission peaks, we calculate an outer disk radius of R_out/a ~0.61, close to the distance of the inner Lagrangian point L_1/a~0.63. Therefore we suggest that, at the time of observations, the accretion disk was filling the Roche-Lobe of the primary, and that the matter leaving the L_1 point was colliding with the disc directly, producing the hot spot at this location.

description: που επικρατούν, όπως η μεγάλη συγκέντρωση ισχύος, η συνήθως μικρή ποσότητα λιπαντικού ελαίου ή γράσου και οι υψηλές επιφανειακές πιέσεις. Για την εφαρμογή της μεθόδου μελέτης της τριβής και των απωλειών, πρέπει να είναι γνωστές οι συνθήκες που επικρατούν. Στα πλαίσια της διατριβής, έγινε η μελέτη της κινηματικής, διαφόρων μορφών κυκλοειδών και αναπτύχθηκαν τα απαραίτητα εργαλεία σχεδίασης και ανάλυσης των μειωτήρων.

Επιτυγχάνεται η αποτίμηση της επίδρασης των γεωμετρικών παραμέτρων στις απώλειες ισχύος.
description: modelling of the limiting shear stress is studied in terms of the calculated friction if an error in the parameters is assumed. Cycloid reducers are planetary systems with a trochoid flank curve that offer advantages such as zero backlash, very small fluctuation of torque and ratio coupled with very high reduction ratios and high power density. These aspects make them a good contestant for highly demanding applications such as robotics. The comparably lower weight of the reducers and the high overload capacity makes them also attractive in personal mobility applications. Tribologically, they present an interesting case due to the high-power density, limited oil or grease supply in conjunction with high normal pressure. In order to apply friction simulation and the aforementioned rheology model, the tribological condition must be evaluated. In this thesis, the kinematic analysis of different configurations is performed. Software tools are developed and used to design and analyse the reducers. The results concerning normal stresses are compared to those obtained using the Finite Element Method. The workflow tools produce input files and utilize the numerical EHL solver. The friction results are used for the calculation of the total power loss. By adjusting the design parameters optimal parameters can be selected for minimizing the power loss and improving the reliability of the reducers.

description: Η παρούσα έρευνα βασίζεται στο χαρακτηρισμό του αστικού πρασίνου ως φυσική δεξαμενή (αποθήκη) άνθρακα, λαμβάνοντας υπόψη ότι η λειτουργία αυτή μεταβάλλεται χρονικά. Με επιλεγμένη περιοχή έρευνας τη Δημοτική Ενότητα Θεσσαλονίκης και αντικείμενα μελέτης τα δένδρα των δενδροστοιχιών της, σκοπός της έρευνας είναι να κατανοηθεί καλύτερα ο τρόπος με τον οποίο η σύνθεση και η δομή του αστικού πρασίνου επηρεάζουν το αστικό κλίμα μέσω της αποθήκευσης CO2 στη βιομάζα των δένδρων. Για να γίνει αυτό χρησιμοποιήθηκαν δείκτες εκτίμησης κυριαρχίας και ποικιλότητας για τη διερεύνηση της σύνθεσης της δενδρώδους βλάστησης, ενώ η δομή εκφράστηκε μέσα από τα δασοκομικά χαρακτηριστικά των ατόμων και τις μεταξύ τους συσχετίσεις. Η ποσότητα άνθρακα που έχει αποθηκευτεί στην υπέργεια βιομάζα των δένδρων στη διάρκεια της ζωής τους, εκτιμήθηκε μέσω αλλομετρικών εξισώσεων, τα αποτελέσματα προσαρμόστηκαν ανάλογα με την κατάσταση της υγείας τους και συγκρίθηκε η πραγματική κατάσταση, με αυτή που θα επικρατούσε αν τα δένδρα διαχειρίζονταν ορθολογικά. Τέλος, έγινε οικονομική εκτίμηση της λειτουργίας αυτής χρησιμοποιώντας το εκτιμώμενο οριακό κοινωνικό κόστος εκπομπών διοξειδίου του άνθρακα.

description: The present research is based on the characterization of urban green as a natural carbon sink that is changing as the trees grow, mature, die and decompose. In the selected research area (Municipal Unit of Thessaloniki) and with its street trees as research subjects, the aim of the research is to determine the relationships between urban green structure and species composition with the city’s climate, as they are expressed via the carbon stored in trees’ biomass. The methodology was based on the calculation and estimation of specialized diversity and dominance indices to scrutinize street trees species composition, while the structure is reflected on the quantity and quality of their silvicultural characteristics and their correlations. In order to organize the field data, an exhaustive tree inventory had been created. Carbon storage capacity of the street trees – during their lifetime - was estimated using allometric equations. The results were adjusted according to the condition of trees’ health and vitality and the real situation was compared with the one, which would have prevailed if the trees were managed rationally and systematically. Finally, the monetary value of street trees role to store carbon was estimated. This information has been mapped in order to obtain a clear view of the spatial variability.

description: Recent searches for the hosts of high-redshift ($z \sim 4$) damped Ly$α$ absorbers (DLAs) have detected bright galaxies at distances of tens of kpc from the DLA. Using the FIRE-2 cosmological zoom simulations, we argue that these relatively large distances are due to a predominantly cool and neutral inner circumgalactic medium (CGM) surrounding high-redshift galaxies. The inner CGM is cool because of the short cooling time of hot gas in $\lesssim10^{12}$ Msun halos, which implies that accretion and feedback energy are radiated quickly, while it is neutral due to the high volume densities and column densities at high redshift which shield cool gas from photoionization. Our analysis predicts large DLA covering factors ($\gtrsim50\%$) out to impact parameters $\sim0.3((1 + z)/5)^{3/2}\ R_{\rm vir}$ from the central galaxies at $z > 1$, equivalent to a physical distance of $\sim 21 M_{12}^{1/3} ((1 + z)/5)^{1/2}$ kpc ($R_{\rm vir}$ and $M_{12}$ are the halo virial radius and mass in units of $10^{12}$ Msun, respectively). This implies that DLA covering factors at $z \sim 4$ may be comparable to unity out to a distance $\sim 10$ times larger than stellar half-mass radii. A predominantly neutral inner CGM in the early universe suggests that its mass and metallicity can be directly constrained by CGM absorption surveys, without resorting to large ionization corrections as required for ionized CGM.

Cardiorespiratory responses of healthy middle-aged men to steady-state positive and negative work performed on a cycle ergometer

description: The physiological responses of negative work involving predominantly eccentric muscle contraction were compared to positive work involving predominantly concentric muscle contraction in twelve older healthy subjects between 39 and G5 years of age. A motorized cycle ergometer was used for steady state exercise testing. To study the physiological response to positive and negative work, pedalling frequencies of 35, 55, and 75 rpm and a constant power output of 60 Watts were chosen. Steady state values of oxygen consumption (VO2), heart rate (HR), minute ventilation (VE), tidal volume <VT) and breathing frequency (fb) were obtained during six test conditions, namely, positive and negative work at each of the three pedalling frequencies. All physiological measures were greater during positive work than negative work (p<0.001) except for fb (p>0.05). The greater VO2 (1.14±.0.13 and 0.62±0.15 1/min (mean+standard deviation) during positive and negative work respectively), HR (95. 8±.10. 7 and 81.8 ± 13.6 bpm) and VE (26.7±5.5 and 16.5±5.2 1/min) during positive work were consistent with the greater energy efficiency of negative work. The greater VE during positive work reflected a greater VT (1.46±.32 1/br) than negative work (0.99±.31 1/br) while fb was the same (18.7±.4.0 and 17.5±5.6 br/min) for both positive and negative work. During positive work, all physiolgical variables were greatest at 75 compared to 35 and 55 rpm (p<0.05) except for fb which showed no significant difference across the three pedalling frequencies
0.05). During negative work, VO2 and HR were greatest at 75 and 35 rpm compared to 55 rpm
0.05). The slopes and intercepts of the regression lines relating HR and VO2, VE and VO2, VT and VE, and fb and VE were identical between positive and negative work except for a higher intercept for the VE and VO2 relationship during negative work. Thus, it was concluded that at a power output of 60 Watts, physiological responses such as VO2, HR and VE during positive and negative work were qualitatively similar. When changes in VT and fb were compared from baseline to steady-state for positive work, however, VT and fb both increased. In contrast, for negative work, VT increased minimally while relatively greater increases in fb were observed for pedalling frequencies of 35 and 55 rpm. The relatively greater effect of negative work on fb compared with positive work is not predicted from the known ventilatory responses to low intensity exercise. Further study is needed to elucidate the precise mechanism for this predominant increase in fb during negative work.
