description: Project briefing for the Coalition for Networked Information (CNI) Spring Meeting April, 2019 in St Louis, Missouri
description: This presentation is part of the Purposeful Space Design for Libraries Session CNI has been working with the Learning Spaces Collaboratory (LSC) to examine how new and renovated spaces can better reflect contemporary needs and contribute to the programmatic priorities of their institution. One way of defining the characteristics of a space is to create a "job description" for it, and that is what groups of participants did at a roundtable co-sponsored by CNI and LSC in December, 2018. We’ll highlight some specific aspects of job descriptions for spaces, including responsibilities, required skills, etc. Another theme of that roundtable, and one heard increasingly in space design circles, is the notion of permeability, space that can be fluid and that changes according to the people using it for particular purposes at particular times. We will include examples of permeable spaces and what they accomplish in academic libraries. Finally, we’ll describe linking assessment to the goals for the space and moving assessment to a mission-critical focus instead of merely a focus on user satisfaction.

Conservation biology

description: In this paper I introduce the concept of biodiversity by means of its peculiar story and defend the importance of biodiversity as an autonomous object of scientific enquiry (Sections 1 and 2). I then discuss two difficulties, (i) the lack of an agreed definition and (ii) the elusiveness of the notion of biodiversity. While I argue that (i) is a problem that can be handled, I suggest that (ii) follows from the vagueness of the concept of diversity and its cognate kind (Sections 3 and 4). Yet, the notion of kind, connecting biodiversity to taxonomy, indicates the path to follow in order to explore what biodiversity is, even though it is a way full of hurdles to overcome (Sections 5 and 6).
Study of some parameters affecting the measured flexural toughness of fiber reinforced concrete
Creators: name: Islam, Shaikh Tashnuba
Publisher: name: University of British Columbia

description: Fiber reinforced concrete (FRC) exhibits better performance not only under static and quasi-statically applied loads, but also under fatigue, impact, and impulsive loading. This energy-absorption attribute of FRC is usually termed “Toughness”. Experimental characterization of the toughness of FRC remains an actively debated topic. In this thesis, concerns with various available techniques were studied and better ways of characterizing the effects of fibers on the toughness of concrete were sought. For toughness characterization, beam tests which included standardized ASTM C1609 and C1399 tests were carried out both on lab-cast and site-cast specimens. In the first part of the study, the applicability of the initial loading rate described in ASTM C1609 was evaluated. Tests were conducted on specimens carrying two volume fractions of polypropylene fiber in two separate series with both the prescribed and proposed loading rates. A comparison between ASTM C1609 and C1399 was carried out later in the study. The Canadian Highway Bridge Design Code (CHDBC) technique prescribed for FRC was also studied. Based on the results of these tests, it can be concluded that the current loading rate specified in ASTM C1609-2010 is too high for normal strength concrete and it should be reduced to 0.001mm/min initially. It was also found that for calculating Residual Strength Index (Ri), ASTM C1609 procedure is more reliable than the ASTM C1399 as ASTM C1609 is performed in a feedback controlled mode (also called the closed-loop mode) which is very helpful for maintaining stability in specimens. Since energy absorption is one of the most effective criteria for characterizing FRC, a new method called Flexural Toughness Strength Method (FTSM) was proposed. Tests are carried out on beam specimens according to ASTM C1609 and load- deflection curves are analyzed using the FTSM method. The results demonstrate that the proposed FTSM leads to FRC attributes that are not susceptible to user errors and hence more reliable. The characterization of flexural toughness based on the FTSM approach is independent of the type of deflection measuring technique and no sophisticated instrumentation is required. The Flexural Toughness Factor calculated using this approach has consistently lower coefficient of variation.

description: Delusion represents an exceptional test case for the principal categories
of common sense and philosophical thought such as ‘reason’, ‘truth’, ‘reality’. With the engagement of a hidden part of Freud’s legacy and the most discussed results of twentieth-century psychiatry, my aim will be to analyze its paradoxical forms and to shed light on the logics that underlie and orient its specific modalities of temporalization, conceptualization and argumentation. Delusion, then, has been traditionally interpreted as synonymous with irrationality (absurdity, groundlessness, error, chaos), whereas by contrast its mirror image, reason, has been defined in terms of evidence, demonstrability, truth and order. I will analyze and contrast their paradoxical definitions.

description: The fourteenth part of the OGLE-III Catalog of Variable Stars (OIII-CVS) contains Cepheid variables detected in the OGLE-II and OGLE-III fields toward the Galactic bulge. The catalog is divided into two main categories: 32 classical Cepheids (21 single-mode fundamental-mode F, four first-overtone 1O, two double-mode F/1O, three double-mode 1O/2O and two triple-mode 1O/2O/3O pulsators) and 335 type II Cepheids (156 BL Her, 128 W Vir and 51 RV Tau stars). Six of the type II Cepheids likely belong to the Sagittarius Dwarf Spheroidal Galaxy. The catalog data include the time-series photometry collected in the course of the OGLE survey, observational parameters of the stars, finding charts, and cross-identifications with the General Catalogue of Variable Stars. We discuss some statistical properties of the sample and compare it with the OGLE catalogs of Cepheids in the Large and Small Magellanic Clouds. Multi-mode classical Cepheids in the Galactic bulge show systematically smaller period ratios than their counterparts in the Magellanic Clouds. BL Her in the Galactic bulge stars seem to be brighter than the linear extension of the period-luminosity relation defined by the longer-period type II Cepheids. We also show individual stars of particular interest, like two BL Her stars with period doubling.

description: We compute the full spectrum and eigenstates of the Kalb-Ramond field in a warped non-compact Randall-Sundrum -type five-dimensional spacetime in which the ordinary four-dimensional braneworld is represented by a sine-Gordon soliton. This 3-brane solution is fully consistent with both the warped gravitational field and bulk dilaton configurations. In such a background we embed a bulk antisymmetric tensor field and obtain, after reduction, an infinite tower of normalizable Kaluza-Klein massive components along with a zero-mode. The low lying mass eigenstates of the Kalb-Ramond field may be related to the axion pseudoscalar. This yields phenomenological implications on the space of parameters, particularly on the dilaton coupling constant. Both analytical and numerical results are given.

description: In this paper, we explore the possibility of spontaneous CP violation in the scattering of quarks and anti-quarks from QCD Z(3) domain walls. The CP violation here arises from the nontrivial profile of the background gauge field $(A_{0})$ between different Z(3) vacua. We calculate the spatial variation of $A_{0}$ across the Z(3) interface from the profile of the Polyakov loop $L(\vec{x})$ for the Z(3) interface and calculate the reflection of quarks and antiquarks using the Dirac equation. This spontaneous CP violation has interesting consequences for the relativistic heavy-ion collision experiments, such as baryon enhancement at high $P_{T}$. It also acts as a source of additional J/$ψ$ suppression. We also discuss its implications for the early universe.

description: A presentation about article: "Model Selection and Prompting Strategies in Resource-Constrained Environments for LLM-based robotic system" that was submitted and presented in EEAI2024 conference.

Large Language Models (LLMs) are increasingly becoming adopted for various applications in information processing and content generation. Coupled with the diverse availability of model weights, quantization, and fine-tuning, it is desirable to find the best-performing LLM within a certain memory budget. Prompting strategy plays a similarly major role in the quality of generation, with various methods existing that attempt to induce desired behaviour, requiring a major time investment to develop. As new models with better performance-to-memory ratios become available, it may be tempting to implement them into an existing system for potential performance improvements. In this work, we explore the process of changing weights and note that weights from larger models or of different quantization precision are unable to replace the original model without modifications to the prompt contents, which in turn implies complications in developing modular, weight-agnostic systems.

description: V393 Scorpii is a Double Periodic Variable characterized by a relatively stable non-orbital photometric cycle of 253 days. Mennickent et al. argue for the presence of a massive optically thick disc around the more massive B-type component and describe the evolutionary stage of the system. In this paper we analyze the behavior of the main spectroscopic optical lines during the long non-orbital photometric cycle. We study the radial velocity of the donor determining their orbital elements and find a small but significant orbital eccentricity (e = 0.04). The donor spectral features are modeled and removed from the spectrum at every observing epoch using the light-curve model given by Mennickent et al. We find that the line emission is larger during eclipses and mostly comes from a bipolar wind. We find that the long cycle is explained in terms of a modulation of the wind strength; the wind has a larger line and continuum emissivity on the high state. We report the discovery of highly variable chromospheric emission in the donor, as revealed by Doppler maps of the emission lines MgII 4481 and CI 6588. We discuss notable and some novel spectroscopic features like discrete absorption components, especially visible at blue-depressed OI 7773 absorption wings during the second half-cycle, Balmer double emission with V/R-curves showing "Z-type" and "S-type" excursions around secondary and main eclipse, respectively, and H_beta emission wings extending up to +- 2000 km/s. We discuss possible causes for these phenomena and for their modulations with the long cycle.

description: We experimentally study the jamming of quasi-two-dimensional emulsions. Our experiments consist of oil-in-water emulsion droplets confined between two parallel plates. From the droplet outlines, we can determine the forces between every droplet pair to within 8% over a wide range of area fractions $ϕ$. We study three bidisperse samples that jam at area fractions $ϕ_c \approx 0.86$. Our data show that for $ϕ> ϕ_c$, the contact numbers and pressure have power-law dependence on $ϕ-ϕ_c$ in agreement with the critical scaling found in numerical simulations. Furthermore, we see a link between the interparticle force law and the exponent for the pressure scaling, supporting prior computational observations. We also observe linear-like force chains (chains of large inter-droplet forces) that extend over 10 particle lengths, and examine the origin of their linearity. We find that the relative orientation of large force segments are random and that the tendency for force chains to be linear is not due to correlations in the direction of neighboring large forces, but instead occurs because the directions are biased towards being linear to balance the forces on each droplet.

Dialect Recognition Using a Phone-GMM-Supervector-Based SVM Kernel

description: In this paper, we introduce a new approach to dialect recognition which relies on the hypothesis that certain phones are realized differently across dialects. Given a speaker’s utterance, we first obtain the most likely phone sequence using a phone recognizer. We then extract GMM Supervectors for each phone instance. Using these vectors, we design a kernel function that computes the similarities of phones between pairs of utterances. We employ this kernel to train SVM classifiers that estimate posterior probabilities, used during recognition. Testing our approach on four Arabic dialects from 30s cuts, we compare our performance to five approaches: PRLM; GMM-UBM; our own improved version of GMM-UBM which employs fMLLR adaptation; our recent discriminative phonotactic approach; and a state-of-the-art system: SDC-based GMM-UBM discriminatively trained. Our kernel-based technique outperforms all these previous approaches; the overall EER of our system is 4.9%.
Anderson lattice with explicit Kondo coupling: general features and the field-induced suppression of heavy-fermion state in ferromagnetic phase

description: We apply the extended (statistically-consistent, SGA) Gutzwiller-type approach to the periodic Anderson model (PAM) in an applied magnetic field and in the strong correlation limit. The finite-U corrections are included systematically by transforming PAM into the form with Kondo-type interaction and residual hybridization, appearing both at the same time. This effective Hamiltonian represents the essence of \textit{Anderson-Kondo lattice model}. We show that in ferromagnetic phases the low-energy single-particle states are strongly affected by the presence of the applied magnetic field. We also find that for large values of hybridization strength the system enters the so-called \textit{locked heavy fermion state}. In this state the chemical potential lies in the majority-spin hybridization gap and as a consequence, the system evolution is insensitive to further increase of the applied field. However, for a sufficiently strong magnetic field, the system transforms from the locked state to the fully spin-polarized phase. This is accompanied by a metamagnetic transition, as well as by drastic reduction of the effective mass of quasiparticles. In particular, we observe a reduction of effective mass enhancement in the majority-spin subband by as much as 20% in the fully polarized state. The findings are consistent with experimental results for Ce$_x$La$_{1-x}$B$_6$ compounds. The mass enhancement for the spin-minority electrons may also diminish with the increasing field, unlike for the quasiparticles states in a single narrow band in the same limit of strong correlations.

description: The last 25 years in libraries have been characterized by constant change, perhaps more than most areas of the academy. Driven first by ubiquitous networked access to information, then by the changing nature of the student experience, notions of library space design have been transformed. Today, a fundamentally new type of library is needed. The Taylor Family Digital Library (TFDL) at the University of Calgary is widely recognized as an instantiation of this new library. A $205M project opened in 2011, the TFDL represents a library not built for permanent housing of collections, but for people interacting in permeable and flexible spaces.

description: Even if he was one of the most famous Dominican saints in late Medieval Italy, present day scholarship is not too fond of Peter of Verona, most often referred to as Peter Martyr. Until recently the most complete study of his life was an article by Antoine Dondaine, published in 1953,  and it was only beninning in the 2000s that historians showed a newfound interest in Peter. Within a span of a few years an article by Christine Caldwell (2000),  the proceedings of a conference held in Milan in 2005,  and a book by Donald Prudlo (2008) appeared.  However art historical studies remain infrequent, and they normally deal with a few significant artworks – Titian’s destroyed altarpiece from San Zanipolo in Venice, for example –, without defining the wider context of petrine imagery, or the problems it engendered.

description: We analyze various aspects of the recently proposed holographic theories with general dynamical critical exponent z and hyperscaling violation exponent $θ$. We first find the basic constraints on $z, θ$ from the gravity side, and compute the stress-energy tensor expectation values and scalar two-point functions. Massive correlators exhibit a nontrivial exponential behavior at long distances, controlled by $θ$. At short distance, the two-point functions become power-law, with a universal form for $θ> 0$. Next, the calculation of the holographic entanglement entropy reveals the existence of novel phases which violate the area law. The entropy in these phases has a behavior that interpolates between that of a Fermi surface and that exhibited by systems with extensive entanglement entropy. Finally, we describe microscopic embeddings of some $θ\neq 0$ metrics into full string theory models -- these metrics characterize large regions of the parameter space of Dp-brane metrics for $p\neq 3$. For instance, the theory of N D2-branes in IIA supergravity has z=1 and $θ= -1/3$ over a wide range of scales, at large $g_s N$.

Hierfür wurden 55 Tumorpräparate aus den Jahren 1998 - 2003 immunhistochemisch untersucht. Die Auswertung erfolgte mit dem Immunreaktiven Score nach Remmele und Stegner. Die Expression von uPA und PAI zeigte keinen direkten Zusammenhang mit den klinisch-pathologischen Parametern Tumorgröße, regionärer Lymphknotenbefall und Fernmetastasen (TNM). Bei einer Überexpression von uPA war das relative Risiko des tumorassoziierten Todes um das 3,8-fache erhöht (p= 0,04). UPA kann als additiver prognostischer Faktor beim oralen Plattenepithelkarzinom herangezogen werden.
description: The present study evaluated the role of uPA and PAI and their prognostic value in oral squamousa cell carcinoma (OSSC). Based upon 55 tissue extracts from 1998 - 2003 the results are not correlating between expression of uPA and PAI an the clinicopathological parameters (TNM). Furthermore uPA expression has a relative risk of 3,8 (p= 0,04) according to tumor-associated death. Therefore the clinical investigation provides significant evidance for uPA as an independent additive-prognostic factor in OSSC.

description: In conversation, speakers become more like each other in various dimensions. This phenomenon, commonly called entrainment, coordination, or alignment, is widely believed to be crucial to the success and naturalness of human interactions. We investigate entrainment in four acoustic and prosodic dimensions. We explore whether speakers coordinate with each other in these dimensions over the conversation as a whole as well as on a turn-by-turn basis and in both relative and absolute terms, and whether this coordination improves over the course of the conversation.

description: We report CO detections in 17 out of 19 infrared ultraluminous QSO (IR QSO) hosts observed with the IRAM 30m telescope. The cold molecular gas reservoir in these objects is in a range of 0.2--2.1$\times 10^{10}M_\odot$ (adopting a CO-to-${\rm H_2}$ conversion factor $α_{\rm CO}=0.8 M_\odot {\rm (K km s^{-1} pc^2)^{-1}}$). We find that the molecular gas properties of IR QSOs, such as the molecular gas mass, star formation efficiency ($L_{\rm FIR}/L^\prime_{\rm CO}$) and the CO (1-0) line widths, are indistinguishable from those of local ultraluminous infrared galaxies (ULIRGs). A comparison of low- and high-redshift CO detected QSOs reveals a tight correlation between L$_{\rm FIR}$ and $L^\prime_{\rm CO(1-0)}$ for all QSOs. This suggests that, similar to ULIRGs, the far-infrared emissions of all QSOs are mainly from dust heated by star formation rather than by active galactic nuclei (AGNs), confirming similar findings from mid-infrared spectroscopic observations by {\it Spitzer}. A correlation between the AGN-associated bolometric luminosities and the CO line luminosities suggests that star formation and AGNs draw from the same reservoir of gas and there is a link between star formation on $\sim$ kpc scale and the central black hole accretion process on much smaller scales.

Leadership Impact on Lecturer Retention at University Preparation Programs in Malaysia

Subjects: subject: Expatriates
subject: Education--Administration

description: The purpose of this study was to understand the importance of leadership and organizational climate among the possible factors that may influence expatriate lecturers (ELs) working at higher education institutions (HEIs) in Malaysia to either renew their contract or depart. The research objective was to provide the leaders of such programs with insights to help them mitigate the challenges expatriates face and develop a supportive environment that encourages longer-term commitment of lecturers to the program beyond an initial contract. A convergent, parallel mixed methods research design was used for this study in which 63 participants completed an online questionnaire. In addition, 31 participants also completed a semi-structured interview. The research population for this study included current and former ELs who have worked at university preparation programs at Malaysian HEIs. This population was purposefully chosen based on their potential to best inform the research questions and enhance understanding of EL retention. Five themes that affect EL retention surfaced from the analysis of the qualitative and quantitative data: (a) professional growth and fulfilment, (b) the direct influence of the leader, (c) institutional factors, (d) cultural adjustment factors, and (e) country-specific factors. These key factors have influenced the decision-making around contract renewal for ELs at Malaysian HEIs. These five themes were analysed in light of the key components of the conceptual framework of this study, and each was examined in relation to this study’s literature review. Based on this, the findings of this study were outlined as: (a) cultural adjustment for expatriates in Malaysia, (b) the Theory of Work Adjustment in relation to expatriate lecturers, (c) determinants of job satisfaction among academic faculty, (d) prioritizing factors affecting expatriate lecturer retention, and (e) key leadership approaches. Based on the results of this study, The Leadership Model for Expatriate Lecturer Satisfaction and Fulfillment was developed in order to guide program directors in developing a system to foster the conditions that encourage EL retention. This study will be of interest to program directors and senior leaders of HEIs in Malaysia.

Community colleges

description: From their beginnings in the early 1900s, community colleges have undergone a significant shift in their purpose and mission. Starting primarily as junior colleges with an emphasis on academics, the colleges are now complex institutions taking on a broad array of educational, social, and economic functions. Many community college advocates hail the comprehensiveness of these institutions, arguing that the ever-expanding mission meets a commitment to serve the changing needs of the community. But critics suggest that the colleges have abandoned educational missions that should form the foundation of a democratic society and squandered effort and resources in an attempt to “be all things to all people.” This paper clarifies the underlying assumptions of both sides in this controversy and reports preliminary findings from a national study of the missions of community colleges. In the long run, additional missions and activities will successfully be carried out by community colleges when they are functionally associated with the core activities of the college and therefore can be carried out in the colleges more efficiently than by other organizations. That is, efforts at expanding missions will be successful to the extent that they are built on complementarities or economies of scope between core college functions— teaching academic and vocational courses—and other activities.
The Franciscan ‘Revolution’ Reconsidered

Literature, Medieval

description: This paper reconsiders the assumption that the textual and visual output of the Franciscan Order is informed by a limpid naturalism which, in turn, enables viewers (and readers) a seamless immersive experience. By focusing on the rhetorical descriptions of Francis of Assisi’s stigmata, the paper reveals the modes whereby those unprecedented wounds were displayed and disseminated in texts and images in the first half of the duecento. The challenge facing the Order was the spectacularisation of a phenomenon that was deemed a profound enigma, and the details of which were guarded jealously as “secrets” by Francis. Consequently, the depiction of the alter Christus was implicated in a complex network of issues that subverted medieval notions of imitation, witness, participation, and representation.

description: We investigate the question of whether the recent modulation signal claimed by CoGeNT is best explained by the dark matter (DM) hypothesis from a Bayesian model comparison perspective. We consider five phenomenological explanations for the data: no modulation signal, modulation due to DM, modulation due to DM compatible with the total CoGeNT rate, and a signal coming from other physics with a free phase but annual period, or with a free phase and a free period. In each scenario, we assign to the free parameters physically motivated priors. We find that while the DM models are weakly preferred to the no modulation model, but when compared to models where the modulation is due to other physics, the DM hypothesis is favoured with odds ranging from 185:1 to 560:1. This result is robust even when astrophysical uncertainties are taken into account and the impact of priors assessed. Interestingly, the odds for the DM model in which the modulation signal is compatible with the total rate against a DM model in which this prior is not implemented is only 5:8, in spite of the former's prediction of a modulation amplitude in the energy range 0.9 to 3.0 keVee that is significantly smaller than the value observed by CoGeNT. Classical hypothesis testing also rules out the null hypothesis of no modulation at the 1.6 sigma to 2.3 sigma level, depending on the details of the alternative. Lastly, we investigate whether anisotropic velocity distributions can help to mitigate the tension between the CoGeNT total and modulated rates, and find encouraging results.

Studies on the regulation of the phosphaturic hormone fibroblast growth factor 23 (FGF23)

description: Fibroblasten-Wachstumsfaktor 23 (FGF23) ist ein aus dem Knochen stammendes Hormon, das den Blutspiegel von Phosphat und aktivem Vitamin D reguliert. Bei diversen menschlichen Erkrankungen, wie Nieren- oder Herz-Kreislauf-Erkrankungen, ist der FGF23-Spiegel verändert, wodurch es auch seine klinische Relevanz erlangt. Zahlreiche Studien belegen eine komplexe Regulation der FGF23-Produktion, die noch lange nicht vollständig verstanden ist. Ausgehend davon, dass Entzündungsreaktionen, die unter anderem zur Aktivierung von speichergesteuerten Ca2+-Einstrom (store-operated Ca2+ entry, SOCE) führen, einer der wichtigsten Auslöser der FGF23-Steigerung sind, lag der Fokus dieser Arbeit auf Untersuchungen von entzündungsrelevanten Vorgängen, die die Regulation von FGF23 beeinflussen können. Dabei konnte gezeigt werden, dass Insulin und AGEs (advanced glycation end products), welche in Verbindung mit chronischen Entzündungserkrankungen wie Diabetes stehen, wichtige Regulator von FGF23 sind.
description: Fibroblast Growth Factor 23 (FGF23) is a bone-derived hormone that regulates blood levels of phosphate and active vitamin D. In various human diseases, such as kidney or cardiovascular diseases, the FGF23 level is altered, which also makes it clinically relevant. Numerous studies demonstrate that the regulation of FGF23 production is complex and far from being fully understood. Based on the fact that inflammatory reactions leading to the activation of storeoperated Ca2+ entry (SOCE), among other things, are one of the most important triggers of FGF23 increase, the focus of this work was on investigations of inflammation-relevant processes that can influence the regulation of FGF23. It could be shown that insulin and AGEs (advanced glycation end products), which are associated with chronic inflammatory diseases such as diabetes, are important regulators of FGF23.
θ-angle monodromy in two dimensions

description: "θ-angle monodromy" occurs when a theory possesses a landscape of metastable vacua which reshuffle as one shifts a periodic coupling θby a single period. "Axion monodromy" models arise when this parameter is promoted to a dynamical pseudoscalar field. This paper studies the phenomenon in two-dimensional gauge theories which possess a U(1) factor at low energies: the massive Schwinger and gauged massive Thirring models, the U(N) 't Hooft model, and the {\mathbb CP}^N model. In all of these models, the energy dependence of a given metastable false vacuum deviates significantly from quadratic dependence on θjust as the branch becomes completely unstable (distinct from some four-dimensional axion monodromy models). In the Schwinger, Thirring, and 't Hooft models, the meson masses decrease as a function of θ. In the U(N) models, the landscape is enriched by sectors with nonabelian θterms. In the {\mathbb CP}^N model, we compute the effective action and the size of the mass gap is computed along a metastable branch.

description: We discuss the direct detection signatures of dark matter interacting with nuclei via a Z' mediator, focussing on the case where both the dark matter and the $Z'$ have mass of a few GeV. Isospin violation (i.e. different couplings to protons and neutrons) arises naturally in this scenario. In particular it is possible to reconcile the preferred parameter regions inferred from the observed DAMA and CoGeNT modulations with the bounds from XENON100, which requires f_n/f_p = -0.7. Moreover, the Z' mediator can also yield a large spin-dependent cross-section which could contribute to the DAMA signal, while the spin-independent cross-section is adequate to explain the CoGeNT signal.

description: Recently, Tseliakhovich and Hirata (2010) showed that during the cosmic Dark Ages the baryons were typically moving supersonically with respect to the dark matter with a spatially variable Mach number. Such supersonic motion may source shocks that heat the Universe. This motion may also suppress star formation in the first halos. Even a small amount of coupling of the 21cm signal to this motion has the potential to vastly enhance the 21cm brightness temperature fluctuations at 15
