The Mathematics and Physics of Diderot. I. On Pendulums and Air Resistance
Creators: name: Dahmen, Silvio R.
Publisher: name: arXiv
Year: 2014
Subjects: subject: History and Philosophy of Physics (physics.hist-ph)
subject: FOS: Physical sciences

description: In this article Denis Diderot's Fifth Memoir of 1748 on the problem of a pendulum damped by air resistance is discussed. Diderot wrote the Memoir in order to clarify an assumption Newton made without further justification in the first pages of the Principia in connection with an experiment to verify the Third Law of Motion using colliding pendulums. To explain the differences between experimental and theoretical values of momentum in the collision experiments he conducted Newton assumed that the bob was retarded by an air resistance $F_R$ proportional to the velocity $v$. By giving Newton's arguments a mathematical scaffolding and recasting his geometrical reasoning in the language of differential calculus, Diderot provides a step-by-step solution guide to the problem and proposes experiments to settle the question about the appropriate form of $F_R$, which for Diderot quadratic in $v$, that is $F_R \sim v^2$. The solution of Diderot is presented in full detail and his results are compared to those obtained from a Lindstedt-Poincare approximation for an oscillator with quadratic damping. It is shown that, up to a prefactor, both coincide. Some results that one can derive from his approach are presented and discussed for the first time. Experimental evidence to support Diderot's or Newton's claims is discussed together with the limitations of their solutions. Some misprints in the original memoir are pointed out.

description: Abstract
This research, conducted at Isabela State University's San Mariano campus in Santa Filomena, San Mariano, Isabela, spanning from April 20, 2020, to June 5, 2020, aimed to assess the impact of Gibberellic acid (GA3) on watermelon fruit quality. The study employed a two-factor experimental design, with the main plot factor representing GA3 concentration, comprising three levels (C1-Control, C2-20 ppm, and C3-30 ppm), and the sub-plot factor representing fruit load, including three levels (T1-2 Fruit per plant, T2-3 Fruit Load per plant, T3-4 Fruit Load per Plant). The experimental layout followed a Split-plot Design and was replicated three times. Results indicated that the application of 30 ppm GA3 led to the production of the heaviest and largest fruits with thicker flesh. However, it is noteworthy that the various GA3 concentrations did not exert a significant influence on sugar content in the fruits. Furthermore, when evaluating the interaction between 30 ppm GA3 and four fruits per plant (C3T3), it was observed that although this combination resulted in the heaviest fruits, it did not yield any positive effects on fruit diameter, fruit weight per sampling area, or sugar content. Nevertheless, all treatment combinations displayed noteworthy variations in terms of flesh thickness. For example, the combination of 30 ppm GA3 concentration and four fruits per plant (C3T1) yielded a remarkable flesh thickness of 8.83. Based on these findings, it is recommended that the practice of applying a 30 ppm GA3 concentration be adopted as a cultural practice for watermelon production. This approach is expected to enhance fruit size and flesh thickness, thereby contributing to improved watermelon quality.

description: The EU-PolarNet white papers were developed by a specially selected team of EU and overseas experts from diverse areas of polar research. These experts were challenged to identify polar research topics with a clear societal relevance and a specific importance for Europe that could make them suitable for future EU support. These topics will, if adopted, further enhance EU research excellence, increase efficient use of European resources and expertise, and lead to a step change in data availability, access and interoperability. They will further increase the scale of polar research cooperation in Europe and, by including non-EU partners, will improve global cooperation. Each of the topics employs a strongly interdisciplinary approach to deliver benefits in the complex and multi-faceted real-world of policy issues. Some of the white papers describe approaches that step outside traditional disciplinary boundaries, offering a transformational or even ‘post-disciplinary’ approach. Each is designed to deliver tangible benefits to problems that arise in the Polar Regions from the complex interactions of a changing physical environment, stressed ecosystems, complex issues of sovereignty and governance, and layered cultural and social structures. The five EU-PolarNet White Papers: White Paper No. 1: The coupled polar climate system: global context, predictability and regional impacts White Paper No. 2: Footprints on Changing Polar Ecosystems: Processes, Threats, Responses and Opportunities for Future Generations White Paper No. 3: Managing human impacts, resource use and conservation of the Polar Regions White Paper No. 4: The Road to the Desired States of Social-ecological Systems in the Polar Regions White Paper No. 5: Advancing operational informatics for Polar Regions

description: The basic stellar atmospheric parameters (effective temperature, surface gravity and global metallicity) were simultaneously determined for a sample of 233 stars, limited in magnitude ($V<15$) with spectral types between G0 and G3 and luminosity class V (main sequence). The analysis was based on spectroscopic observations collected at the Observatorio Astrofísico Guillermo Haro and using a set of Lick-like indices defined in the spectral range of 3800-4800 $Å$. An extensive set of indices computed in a grid of theoretical spectra was used as a comparison tool in order to determine the photospheric parameters. The method was validated by matching the results from spectra of the asteroids Vesta and Ceres with the Sun parameters. The main results were: i) the photospheric parameters were determined for the first time for 213 objects in our sample; ii) a sample of 20 new super metal-rich stars candidates was found.

description: The computational performance of supercomputers is usually expressed in terms of their theoretical peak performance, or measured with rather simple and easy to handle benchmark codes, like the High-Performance Linpack Benchmark, a measure of the floating-point computing power. These metrics allow to easily rank the performance of computers but have only limited value when it comes to the question of how well a computer system is suited for specific complex applications like weather and climate models.
 The EU-funded project ESCAPE-2, which ran from 2019 to 2021, therefore developed a benchmark suite called High Performance Weather and Climate Benchmark, in short HPCW, which consists of widely used European weather and climate models and standalone model components (also called dwarfs in the ESCAPE-2 context) that are less complex than the models themselves but represent selected characteristics of the models. After the end of ESCAPE-2, the centre of excellence ESiWACE2 took over the responsibility to establish HPCW as a useful tool for the communities of weather and climate modellers on the one hand, and for computer manufacturers on the other hand. At the end of ESiWACE2 we provide a consolidated and extended version of HPCW that has been installed and tested on some of the largest high performance computing systems in Europe. The work will be continued in the third phase of the centre of excellence, ESiWACE3.

description: The Gemini Remote Access to CFHT ESPaDONS Spectrograph has achieved first light of its experimental phase in May 2014. It successfully collected light from the Gemini North telescope and sent it through two 270 m optical fibers to the the ESPaDOnS spectrograph at CFHT to deliver high-resolution spectroscopy across the optical region. The fibers gave an average focal ratio degradation of 14% on sky, and a maximum transmittance of 85% at 800nm. GRACES achieved delivering spectra with a resolution power of R = 40,000 and R = 66,000 between 400 and 1,000 nm. It has a ~8% throughput and is sensitive to target fainter than 21st mag in 1 hour. The average acquisition time of a target is around 10 min. This project is a great example of a productive collaboration between two observatories on Maunakea that was successful due to the reciprocal involvement of the Gemini, CFHT, and NRC Herzberg teams, and all the staff involved closely or indirectly.

description: The stationary distributions of sums of positions of trajectories generated by the logistic map have been found to follow a basic renormalization group (RG) structure: a nontrivial fixed-point multi-scale distribution at the period-doubling onset of chaos and a Gaussian trivial fixed-point distribution for all chaotic attractors. Here we describe in detail the crossover distributions that can be generated at chaotic band-splitting points that mediate between the aforementioned fixed-point distributions. Self affinity in the chaotic region imprints scaling features to the crossover distributions along the sequence of band splitting points. The trajectories that give rise to these distributions are governed first by the sequential formation of phase-space gaps when, initially uniformly-distributed, sets of trajectories evolve towards the chaotic band attractors. Subsequently, the summation of positions of trajectories already within the chaotic bands closes those gaps. The possible shapes of the resultant distributions depend crucially on the disposal of sets of early positions in the sums and the stoppage of the number of terms retained in them.

description: Poster presented at the #GHRSST23 science team meeting, 27 June-1 July 2022. Abstract As the size and complexity of the Earth observation data catalogue grows, the ways in which we interface with it must adapt to accommodate the needs of end users, both research-focussed and operational. Consequently, since 2020 EUMETSAT have introduced a suite of new data services to improve the ability of users to view, access and customise the Earth observation data catalogue they provide. These services, which are now operational, offer both GUI- and API- based services and allow fine grained control over how users interact both with products, and the collections they reside in. From early 2022, these services will also support the dissemination of the EUMETSAT Copernicus Marine Data Stream, including the Level-1 and Level-2 marine products from both the Sentinel-3 and Sentinel-6 missions at both near real-time and non-time-critical latency. Here, we give an overview of the capability of these data services, with examples of how to use them. In addition, we will outline the tools and resources that are available to assist users in incorporating these services into their workflows and applications. These include online user guides, python libraries and command line approaches to facilitate data access, and a suite of self-paced training resources and courses. This poster presentation will include demonstrations of the services, information on plans and schedules for the inclusion of future data streams, and the opportunity for new and experienced users to ask questions and give feedback.
Observing multiple stellar populations with FORS2@VLT - Main sequence photometry in outer regions of NGC 6752, NGC 6397, and NGC 6121 (M 4)

description: We present the photometric analysis of the external regions of three Galactic Globular Clusters: NGC 6121, NGC 6397 and NGC 6752. The main goal is the characterization of the multiple stellar populations along the main sequence (MS) and the study of the radial trend of the different populations hosted by the target clusters. The data have been collected using FORS2 mounted at the ESO/VLT@UT1 telescope in UBVI filters. From these data sets we extracted high-accuracy photometry and constructed color-magnitude diagrams. We exploit appropriate combination of colors and magnitudes which are powerful tools to identify multiple stellar populations, like B versus U-B and V versus c_{U,B,I}=(U-B)-(B-I) CMDs. We confirm previous findings of a split MS in NGC 6752 and NGC 6121. Apart from the extreme case of omega Centauri, this is the first detection of multiple MS from ground-based photometry. For NGC 6752 and NGC 6121 we compare the number ratio of the blue MS to the red MS in the cluster outskirts with the fraction of first and second generation stars measured in the central regions. There is no evidence for significant radial trend. The MS of NGC 6397 is consistent with a simple stellar population. We propose that the lack of multiple sequences is due both to observational errors and to the limited sensitivity of U,B,V,I photometry to multiple stellar populations in metal-poor GCs. Finally, we compute the helium abundance for the stellar populations hosted by NGC 6121 and NGC 6752, finding a mild (Delta Y ~ 0.02) difference between stars in the two sequences.

description: We show that an analog of the physics at the Planck scale can be found in the propagation of tightly focused laser beams. Various equations that occur in generalized quantum mechanics are formally identical to those describing the nonlinear nonlocal propagation of nonparaxial laser beams. The analysis includes a generalized uncertainty principle and shows that the nonlinear focusing of a light beam with dimensions comparable to the wavelength corresponds to the spontaneous excitation of the so-called maximally localized states. The approach, driven by the ideas of the quantum gravity physics, allows one to predict the existence of self-trapped subwavelength solitary waves for both focusing and defocusing nonlinearities, and opens the way to laboratory simulations of phenomena that have been considered to be inaccessible.

description: TheEuropean Polar Research Programme is the outcome of a five-year process of co-designing and co-developing a future research agenda for Europe which has been performed within the EU-PolarNet consortium. One of the challenges consisted in the careful collection of the highly diverse polar stakeholder needs by implementing a series of engagement actions. Another key challenge was to translate these needs into prioritised research questions. This work was achieved by involving a wide range of polar experts and combining their expertise. In addition, the European Polar Research Programme was subject to a thorough review by different scientific and polar specialists in and outside the EU-PolarNet consortium. The European Polar Research Programme is organised in six main chapters dealing with overarching, cross-cutting research issues which should lead to major advances in the understanding of the Polar Regions. In total, the chapters highlight a number of research issues ranging from improved characterisation and understanding of the physical, environmental, societal, cultural and economic conditions, and the current changes and evolutions in the Polar Regions to better definition, prediction and projection of their future conditions, thus supporting adaptation and resilience to the changes. Major challenges identified in the EPRP relate to the actual implementation of research in terms of co-creation of knowledge, leveraging resources and enhanced international cooperation for the benefit of society at large.

description: We measured the transverse magnetoresistivity of the mixed valence compound $α$-YbAlB$_4$. Two configurations were used where current was applied along [110] direction for both and magnetic field was applied along [-110] and $c$-axis. We found the transverse magnetoresistivity is highly anisotropic. In the weak field below 1 T, it is consistent with stronger $c$-$f$ hybridization in the $ab$ plane which was suggested from the previous zero field resistivity measurements. At the higher field above 3 T, we observed a negative transverse magnetoresistivity for the field applied along the $c$-axis. The temperature dependences of the resistivity measured at several different fields suggest the suppression of the heavy fermion behavior at the characteristic field of $\sim 5.5$ T.

description: Suppose $G$ is a compact Lie group, $H$ is a closed subgroup of $G$, and the homogeneous space $G/H$ is connected. The paper investigates the Ricci flow on a manifold $M$ diffeomorphic to $[0,1]\times G/H$. First, we prove a short-time existence and uniqueness theorem for a $G$-invariant solution $g(t)$ satisfying the boundary condition $\mathop{\mathrm{II}}(g(t))=F(t,g_{\partial M}(t))$ and the initial condition $g(0)=\hat g$. Here, $\mathop{\mathrm{II}}(g(t))$ is the second fundamental form of $\partial M$, $g_{\partial M}$ is the metric induced on $\partial M$ by $g(t)$, $F$ is a smooth map and $\hat g$ is a metric on $M$. Second, we study Perelman's $\mathcal F$-functional on $M$. Our results show, roughly speaking, that $\mathcal F$ is non-decreasing on a $G$-invariant solution to the modified Ricci flow, provided that this solution satisfies boundary conditions inspired by the 2012 paper of Gianniotis.

description: When fixing a covariant gauge, most popularly the Landau gauge, on the lattice one encounters the Neuberger 0/0 problem which prevents one from formulating a Becchi--Rouet--Stora--Tyutin symmetry on the lattice. Following the interpretation of this problem in terms of Witten-type topological field theory and using the recently developed Morse theory for orbifolds, we propose a modification of the lattice Landau gauge via orbifolding of the gauge-fixing group manifold and show that this modification circumvents the orbit-dependence issue and hence can be a viable candidate for evading the Neuberger problem. Using algebraic geometry, we also show that though the previously proposed modification of the lattice Landau gauge via stereographic projection relies on delicate departure from the standard Morse theory due to the non-compactness of the underlying manifold, the corresponding gauge-fixing partition function turns out to be orbit independent for all the orbits except in a region of measure zero.

description: Evidence is mounting that a significant fraction of the early-type galaxy population contains substantial reservoirs of cold interstellar gas and dust. We investigate the gas and dust in NGC 5485, an early-type galaxy with a prominent minor-axis dust lane. Using new Herschel PACS and SPIRE imaging data, we detect 3.8 x 10^6 Msun of cool interstellar dust in NGC 5485, which is in stark contrast with the non-detection of the galaxy in sensitive HI and CO observations from the ATLAS3D consortium. The resulting gas-to-dust ratio upper limit is Mgas/Md < 14.5, almost an order of magnitude lower than the canonical value for the Milky Way. We scrutinize the reliability of the dust, atomic gas and molecular gas mass estimates, but these do not show systematic uncertainties that can explain the extreme gas-to-dust ratio. Also a warm or hot ionized gas medium does not offer an explanation. A possible scenario could be that NGC 5485 merged with an SMC-type metal-poor galaxy with a substantial CO-dark molecular gas component and that the bulk of atomic gas was lost during the interaction, but it remains to be investigated whether such a scenario is possible.

description: Abstract
The study was conducted to evaluate the utilization of varying levels of Pterocarpus mildbraedii leaf meal (PMLM) by broiler chickens. A total of 150 Arbor Acre day old chicks were acquired and subjected to a feeding trial for 4 weeks. The effects of PMLM were measured on growth performance, blood parameters and organ morphology of broiler chickens. The birds were randomly assigned to 5 dietary treatments: 0.1%PMLM, 0.2%PMLM, 0.4% PMLM, 0%PMLM with antibiotics (control) and 0%PMLM without antibiotics (control). Treatments composed of 3 replications at 10 birds per replicate. The experimental design used was Completely Randomised Design (CRD). Results indicated that inclusion of PMLM inclusion did not significantly influence (p>0.05) the performance characteristics (body weight, weight gain, feed intake and feed conversion ratio). The inclusion of the supplements did not also significantly affect (p>0.05) all the haematological parameters measured except platelets where birds fed 0.2%PMLM supplements had significantly higher (p<0.05) value (148.25 ± 12.15) when compared to other treatments. Birds fed 0.2%PMLM supplements had significantly higher (p<0.05) values for albumin and globulin (1.91 ± 0.07g/dL and 0.83 ± 0.56g/dL respectively) but no significant difference (p>0.05) was recorded for glucose, total protein and creatinine.  The supplementation did not also significantly affect (p>0.05) the weights of heart, spleen and liver but significant difference (p<0.05) was observed for the gizzard, small and large intestines.The use of PMLM in the diets of broiler chickens up to 0.4% supplementation level could be effectively utilized without any deleterious effect and for optimum performance.

description: Low-energy magnon excitations in multiferroic BiFeO$_3$ were measured in detail as a function of temperature around several Brillouin zone centers by inelastic neutron scattering experiments on single crystals. Unique features around 1 meV are directly associated with the interplay of the Dzyaloshinskii-Moriya interaction and a small single-ion anisotropy. The temperature dependence of these and the exchange interactions were determined by fitting the measured magnon dispersion with spin-wave calculations. The spectra best fits an easy-axis type magnetic anisotropy and the deduced exchange and anisotropy parameters enable us to determine the anharmonicity of the magnetic cycloid. We then draw a direct connection between the changes in the parameters of spin Hamiltonian with temperature and the physical properties and structural deformations of BiFeO$_3$.

description: Apoptosis, repair and senescence are tools which an organism can use in a risk management process that balances the threats posed by damaged, existing cells against the difficulty and cost of replacing them. If they are orchestrated effectively the organism can gain a degree of risk reduction, appropriate for a particular tissue and time of life, at minimum cost.
Where abundant resources allow, apoptosis eliminates risks posed by damaged cells. Where resources are constrained, senescence trades immediate threats posed by damaged cells for longer-term risks including inflammation, metastasis and epigenetic instability. Pushing risks into the future is consistent with an evolutionary need to keep an organism adequately healthy, for sufficiently long, that it can raise healthy offspring.
Negative consequences of senescence can be minimised by ensuring that senescence is rarely needed. Where senescence is unavoidable, it is desirable to engineer outcomes that halt proliferation without altering or damaging chromatin.

title: Overseas Development Aid for Humanitarian Crises: Implications for the Recovery of Shelter and Settlements
Creators: name: Babister, Elizabeth Anne Rosambeau
Publisher: name: The Open University
Year: 2022

description: This interdisciplinary research draws on the fields of international development and political economy. A gap is present in current evidence to support the conceptualisation of humanitarian donorship and specifically the causal links between donorship mechanics and the ability of those affected by crises to recover. This research investigates the question of why it is challenging for donors to align the characteristics of their humanitarian funding with the lived experience of those who lose their shelter and settlements in humanitarian crises. The research takes a qualitative ethnographic approach using primary and secondary data bounded by a case study of Overseas Development Aid (ODA) for the recovery of shelter and settlements. The theoretical framework uses a critical accounting approach based on Miller and Power’s four roles of accounting (Miller & Power, 2013). Miller and Power’s original framework is extended from these accounting roles to include the broader economic practices of humanitarian donorship. This research finds that while donorship with the characteristics of flexibility and a longer-term perspective aligns well with the lived experience of those who lose their shelter and settlements in humanitarian crises, these characteristics are challenging for donors. Exogenous influences incentivise donors towards short-termism, restricting longer-term approaches, and endogenous influences create rigidity in funding processes, preventing flexibility. Together the lack of longer-term approaches and the lack of flexibility contributes to insufficient support to the agency of affected households over the lived experience of the recovery of their shelter and settlements. The research findings inform humanitarian policy and practice and in particular humanitarian donorship for the recovery of shelter and settlements.
Point particles in 2+1 dimensions: general relativity and loop gravity descriptions

description: We develop a Hamiltonian description of point particles in (2+1)-dimensions using connection and frame-field variables for general relativity. The topology of each spatial hypersurface is that of a punctured two-sphere with particles residing at the punctures. We describe this topology with a CW complex (a collection of two-cells glued together along edges), and use this to fix a gauge and reduce the Hamiltonian. The equations of motion for the fields describe a dynamical triangulation where each vertex moves according to the equation of motion for a free relativistic particle. The evolution is continuous except for when triangles collapse (i.e. the edges become parallel) causing discrete, topological changes in the underlying CW complex. We then introduce the loop gravity phase space parameterized by holonomy-flux variables on a graph (a network of one-dimensional links). By embedding a graph within the CW complex, we find a description of this system in terms of loop variables. The resulting equations of motion describe the same dynamical triangulation as the connection and frame-field variables. In this framework, the collapse of a triangle causes a discrete change in the underlying graph, giving a concrete realization of the graph-changing moves that many expect to feature in full loop quantum gravity. The main result is a dynamical model of loop gravity which agrees with general relativity and is well-suited for quantization using existing methods.

A statistical study of recently quenched galaxies in groups and clusters

description: Recently quenched galaxies (RQGs), as a transitional population between quiescent and star-forming galaxies, can efficiently deliver information on quenching processes. A statistical sample of RQGs is necessary for studying mass and environment dependence of quenching. However, the rarity of RQGs hampers statistical spectroscopic analysis. As a pilot work, we conduct a statistical photometric study of RQGs. Using the rest-frame UVJ diagram, we can select RQGs from various environments and separate them by quenching timescales. Based on this, we conducted statistical analysis of UVJ classified galaxy populations in photometrically selected clusters and X-ray detected groups in COSMOS field. We use the ratio of different galaxy population to quantify the quenching efficiency. For galaxies within HST coverage, we also analyzed the mass and environment dependence of their structural parameters. By these analysis, we are able to further understand the quenching scenario at different redshifts.

description: The steroid hormone 20-hydroxy-ecdysone (20E) promotes proliferation in Drosophila wing precursors at low titer but triggers proliferation arrest at high doses. Remarkably, wing precursors proliferate normally in the complete absence of the 20E receptor, suggesting that low-level 20E promotes proliferation by overriding the default anti-proliferative activity of the receptor. By contrast, 20E needs its receptor to arrest proliferation. Dose-response RNA sequencing (RNA-seq) analysis of ex vivo cultured wing precursors identifies genes that are quantitatively activated by 20E across the physiological range, likely comprising positive modulators of proliferation and other genes that are only activated at high doses. We suggest that some of these "high-threshold" genes dominantly suppress the activity of the pro-proliferation genes. We then show mathematically and with synthetic reporters that combinations of basic regulatory elements can recapitulate the behavior of both types of target genes. Thus, a relatively simple genetic circuit can account for the bimodal activity of this hormone.

description:

Quando, nel 1954, furono pubblicati i due volumi di Gino Gorla dedicati a “Il Contratto” la dottrina italiana del diritto civile, imbevuta di concettualismo pandettistico, quasi non se ne accorse. D’altronde era difficile che potesse accettare una visione realista e funzionale del diritto che metteva in dubbio le sue certezze e offriva una lettura non dogmatica di un istituto, il contratto, che vive e si sviluppa nel quotidiano agire sociale ed economico. Che, poi, un accademico si cimentasse nella analisi della prosaica giurisprudenza era, se non una eresia, quantomeno una bizzarria. Ben diversa fu l’attenzione – pur ostacolata dalla barriera linguistica – con la quale l’opera fu accolta all’estero, sia per la profondità del pensiero che per il metodo casistico proposto ed applicato alla comparazione giuridica. A distanza di settant’anni  “Il Contratto” di Gorla conserva ancora la freschezza di pensiero non convenzionale e costituisce un punto di riferimento essenziale   per il giurista che voglia studiare l’istituto sia nella dimensione domestica che in quella comparata. E troverà nel secondo volume una messe di casi che tuttora costituiscono validi esempi delle ratio decidendi inespresse sulle quali poggia la giurisprudenza del presente.

description: We study the Initial Mass Function (IMF) and host halo properties of Intermediate Mass Black Holes (IMBH, 10^{4-6} Msun) formed inside metal-free, UV illuminated atomic cooling haloes (virial temperature T_vir > 10^4 K) either via the direct collapse of the gas or via an intermediate Super Massive Star (SMS) stage. We achieve this goal in three steps: (a) we derive the gas accretion rate for a proto-SMS to undergo General Relativity instability and produce a direct collapse black hole (DCBH) or to enter the ZAMS and later collapse into a IMBH; (b) we use merger-tree simulations to select atomic cooling halos in which either a DCBH or SMS can form and grow, accounting for metal enrichment and major mergers that halt the growth of the proto-SMS by gas fragmentation. We derive the properties of the host halos and the mass distribution of black holes at this stage, and dub it the "Birth Mass Function"; (c) we follow the further growth of the DCBH due to accretion of leftover gas in the parent halo and compute the final IMBH mass.We consider two extreme cases in which minihalos (T_vir < 10^4 K) can (fertile) or cannot (sterile) form stars and pollute their gas leading to a different IMBH IMF. In the (fiducial) fertile case the IMF is bimodal extending over a broad range of masses, M= (0.5-20)x10^5 Msun, and the DCBH accretion phase lasts from 10 to 100 Myr. If minihalos are sterile, the IMF spans the narrower mass range M= (1-2.8)x10^6 Msun, and the DCBH accretion phase is more extended (70-120 Myr). We conclude that a good seeding prescription is to populate halos (a) of mass 7.5 < log (M_h/Msun) < 8, (b) in the redshift range 8 < z < 17, (c) with IMBH in the mass range 4.75 < log (M_BH/Msun) < 6.25.
