description: We report on experimental studies on the collective behavior of a strongly interacting Fermi gas with tunable interactions and variable temperature. A scissors mode excitation in an elliptical trap is used to characterize the dynamics of the quantum gas in terms of hydrodynamic or near-collisionless behavior. We obtain a crossover phase diagram for collisional properties, showing a large region where a non-superfluid strongly interacting gas shows hydrodynamic behavior. In a narrow interaction regime on the BCS side of the crossover, we find a novel temperature-dependent damping peak, suggesting a relation to the superfluid phase transition.

description: We investigate the behavior of a circuit QED device when the resonator is initially populated with a mesoscopic coherent field. The strong coupling between the cavity and the qubit produces an entangled state involving mesoscopic quasi-pointer states with respect to cavity dissipation. The overlap of the associated field components results in collapse and revivals for the Rabi oscillation. Although qubit relaxation and dephasing do not preserve these states, a simple analytical description of the dissipative dynamics of the circuit QED device including cavity relaxation as well as qubit dissipation is obtained from the Monte-Carlo approach. Explicit predictions for the spontaneous and induced Rabi oscillation signals are derived and sucessfully compared with exact calculations. We show that these interesting effects could be observed with a 10 photon field in forthcoming circuit QED experiments.

description: Philonthus neoniger Solodovnikov, nom. nov. Taxonomy Philonthus neoniger (the original combination Xanthopygoides niger) is here moved from the subtribe Xanthopygina to Philonthus, the type genus of the subtribe Philonthina. This transfer is based on the following complex of character states shared by P. neoniger with other members of Philonthus: lack of empodial setae; pronotal hypomeron with superior marginal line deflexed under anterior angle of pronotum, and inferior marginal line becoming obsolete near lateral margin of procoxal cavity, both lines not joining each other (Fig. 2); prosternum fused to pronotum, notosternal sutures indistinct (Fig. 2); no translucent postcoxal process of pronotal hypomeron (Fig. 2); entire ligula; no infraorbital and mandibular ridges on head capsule. Such features of Philonthus neoniger as smooth pronotal disk with only one puncture in each of two dorsal “rows”, dense and rugose punctation of elytra and abdomen, and, especially, a rather peculiar shape of the aedeagus (Figs 3,4) allow it to be unambiguously placed in the subgenus Raucalius Tottenham, 1949. Members of the subtribe Xanthopygina, instead, are usually characterized by a complete postmandibular ridge; the inferior marginal line of pronotal hypomeron well separated from the superior marginal line, both lines continuing uninterrupted and separated along the prosternal margin. Also, unlike Philonthina, all members of Xanthopygina have a pair of empodial setae (Smetana and Davies 2000).

A functional analysis of the kalDNA plasmid from senescent strains of Neurospora intermedia
Creators: name: Vickery, Daniel Barry
Publisher: name: University of British Columbia
Year: 2011

description: The 8.6 kb kalilo linear mitochondrial plasmid of Neurospora intermedia was found to give rise to multiple transcripts of 8.6, 4.4, 4.0, 1.3, 1.2, and 0.9 kb. A transcription map has been generated which shows similarities to other linear plasmids. These transcripts are all transcribed from a single, unique promoter sequence reiterated near the ends of the terminal inverted repeats of the linear plasmid. The transcripts are not processed, but instead utilize optional transcription stop sites. An analysis of sub-cellular RNA fractions has confirmed the mitochondrial location of kalilo transcription. The strong association of kalilo-specific RNA with rRNA to yield RNA artifacts is reported. Kalilo-specific RNA appears to be selectively unstable in affected strains of N. intermedia; this may be a general consequence of linear plasmid RNA. The 5' RNA start site was determined by primer extension and RNA sequencing. The sequence in this region does not show homology to any known mitochondrial, plasmid, nor nuclear promoter, and may constitute a novel element. The transcription start site shares homology with the terminus of the linear plasmid, and marks the end of a long series of direct repeats; therefore, the plasmid RNA polymerase may be bifunctional, it may recognize sequences at the ends of the plasmid as well as at the promoter. The analysis of the insertional behaviour of the linear mitochondrial plasmid was studied in parallel subculture series of the organism. It was determined that insertion, per se is not the event required to kill the organism. Generation of inserts of kalilo in the mtDNA is necessary, but not sufficient, for death to occur in all cases. An analysis of insertion sites has found one new site and good agreement with previously published locations. Insertion does not always appear to be random, so cultures may inherit undetectable amounts of mtlS-kalDNA. The analysis of insertion sites in one strain has suggested a novel possible structure for the mtDNA.

description: Excessive fluoride ingestion during tooth development can cause dental fluorosis. Previously, we reported that fluoride activates histone acetyltransferase (HAT) to acetylate p53, promoting fluoride toxicity in mouse ameloblast-like LS8 cells. However, the roles of HAT and histone acetylation status in fluoride-mediated gene expression remain unidentified. Here, we demonstrate that fluoride-mediated histone modification causes gene expression alterations in LS8 cells. LS8 cells were treated with or without fluoride followed by ChIP-Seq analysis of H3K27ac. Genes were identified by differential H3K27ac peaks within ±1 kb from transcription start sites. The levels of mRNA of identified genes were assessed using rea-time PCR (qPCR). Fluoride increased H3K27ac peaks associated with Bax, p21, and Mdm2 genes and upregulated their mRNA levels. Fluoride decreased H3K27ac peaks and p53, Bad, and Bcl2 had suppressed transcription. HAT inhibitors (Anacardic acid or MG149) suppressed fluoride-induced mRNA of p21 and Mdm2, while fluoride and the histone deacetylase (HDAC) inhibitor sodium butyrate increased Bad and Bcl2 expression above that of fluoride treatment alone. To our knowledge, this is the first study that demonstrates epigenetic regulation via fluoride treatment via H3 acetylation. Further investigation is required to elucidate epigenetic mechanisms of fluoride toxicity in enamel development.

description: In this work we study the spectral functions of scalar mesons in one- and two-channel cases. When the propagators satisfy the Källen-Lehman representation a normalized spectral function is obtained, allowing to take into account finite-width effects in the evaluation of decay rates. In the one-channel case, suitable to the light sigma and k mesons, the spectral function can deviate consistently from a Breit-Wigner shape. In the two-channel case with one subthreshold channel the evaluated spectral function is well approximated by a Flatte' distribution; when applying the study to the a_0(980) and f_0(980) mesons the tree-level forbidden KK decay is analysed.

description: System wolnego wybiegu ma na celu poprawę dobrostanu zwierząt i jest powszechny w produkcji ekologicznej. Może jednak negatywnie oddziaływać na środowisko poprzez emisje biogenów i gazów cieplarnianych z odchodów zwierząt. Prawo określa maksymalną możliwą obsadę inwentarza, pod warunkiem równomiernego rozprowadzenia ich odchodów na pastwisku, dzięki czemu składniki mineralne mogą być pobrane przez korzenie roślin. W praktyce te założenia nie mogą być spełnione: np. świnie często decydują się na defekację w jednym wybranym miejscu wybiegu; gleby piaszczyste absorbują składniki mineralne w niewielkiej ilości; aktywność pobierania substancji przez roślinność różni się pomiędzy sezonami (przy największym pobraniu wiosną) (Tagliapietra i in. 2007).
Drzewa, szczególnie te szybko rosnące, jak topola, (ale również wierzba czy robinia) pochłaniają duże ilości składników mineralnych i mogą ograniczyć ich wymywanie z gleb do wód (AA.VV. 2011). Ponadto, dojrzałe drzewa poprawiają dobrostan zwierząt: dostarczają cienia w upalne dni i osłony przed wiatrem w dni chłodne.

description: In surveys, the interest lies in estimating finite population parameters such as population totals and means. In most surveys, some auxiliary information is available at the estimation stage. This information may be incorporated in the estimation procedures to increase their precision. In this article, we use random forests to estimate the functional relationship between the survey variable and the auxiliary variables. In recent years, random forests have become attractive as National Statistical Offices have now access to a variety of data sources, potentially exhibiting a large number of observations on a large number of variables. We establish the theoretical properties of model-assisted procedures based on random forests and derive corresponding variance estimators. A model-calibration procedure for handling multiple survey variables is also discussed. The results of a simulation study suggest that the proposed point and estimation procedures perform well in term of bias, efficiency and coverage of normal-based confidence intervals, in a wide variety of settings. Finally, we apply the proposed methods using data on radio audiences collected by Médiamétrie, a French audience company.

Sources of information utilized by British Columbia exporters to identify business opportunities in ASEAN : an interview study
Creators: name: Carter, Michael T.
Publisher: name: University of British Columbia
Year: 2012

description: This thesis reports on the results of an interview-based survey of 21 British Columbia exporters active in the ASEAN region. The primary focus of the research was on the sources of information utilized by these exporters in uncovering their initial and most recent business opportunities in the ASEAN market. The respondents in the study displayed a clear preference for sources of information which were external to their organizations rather than internal and for personal sources of information rather than non-personal or documentary sources (including electronic databases). The single most important source of information on potential business opportunities in ASEAN was the personal network of contacts developed by the firm's own personnel, particularly the firm's local man in the field (whether he be an agent, distributor, or joint venture partner). Contrary to the U.S., Swedish and European experience described elsewhere in the literature, the respondents in this study rarely entered the ASEAN market on the basis of an "unsolicited export order". Nor did they attach much importance to bankers, consultants, brokers, lawyers, or government officials as sources of potentially useful information on new business opportunities in ASEAN. Also surprising was the fairly common usage of a "piggyback" or "big brother" method of initial market entry into ASEAN. In most of these cases, the respondents acted as subcontractors to larger Canadian and American firms active in the ASEAN marketplace. Equally surprising was the conspicuous lack of success enjoyed by two B.C. export consortiums formed to penetrate the ASEAN market. Finally, there was very little evidence of any major shift in the type of information sources used, over time. The best sources of information remained "personal contacts" and "the local man in the field". There was, however, some movement away from the use of personal contacts established by the firm's senior executives while on a preliminary swing through the region and towards the use of personal contacts established by the firm's local representative. In addition, there was a growing trend towards the use of indigenous or "bumiputra" representatives in ASEAN and away from the use of Chinese or expatriate middlemen.

Lochy oraz prosięta mogą skryć się w cieniu drzew podczas upalnych dni i osłonić przed deszczem i wiatrem. Ponadto, zwierzęta wykorzystują drzewa do czochrania się. Wprowadzenie drzew na pastwisku ogranicza wymywanie azotanów z gleb, ponieważ ich systemy korzeniowe są bardziej odporne na rycie niż korzenie traw. Ponadto, wykorzystują wodę i składniki mineralne z głębszych warstw gleby. Drzewa dostarczają biomasy energetycznej oraz materiału ściółkowego w "domkach" dla świń. Mają również korzystny wpływ na bioróżnorodność i estetykę krajobrazu.

description: Background: Anti-SARS-CoV-2 monoclonal antibodies (mAbs) have played a key role as an antiviral against SARS-CoV-2, but there is a potential for resistance to develop. The interplay between host antibody responses and the development of monoclonal antibody (mAb) resistance is a critical area of investigation. In this study, we assessed host neutralizing antibody (nAb) responses against both ancestral virus and those with treatment-emergent E484K bamlanivimab resistance mutations. Methods: Study participants were enrolled in the ACTIV-2/Advancing Clinical Therapeutics Globally (ACTG) A5401 phase 2 randomized, placebo-controlled trial of bamlanivimab 700 mg mAb therapy (NCT04518410). Anterior nasal and nasopharyngeal swabs were collected for SARS-CoV-2 RNA testing and S gene next-generation sequencing to identify the E484K bam-lanivimab resistance mutation. Serum nAb titers were assessed by pseudovirus neutralization assays. Results: Higher baseline (pre-treatment) nAb titers against either ancestral or E484K virus was associated with lower baseline viral load. Participants with emerging resistance had low levels of nAb titers against either ancestral or E484K nAb at the time of study entry. Participants with emergent E484K resistance developed significantly higher levels of E484K-specific nAb titers compared to mAb-treated individuals who did not develop resistance. All participants who developed the E484K mAb resistance mutation were eventually able to clear the virus. Conclusion: Emerging drug resistance after SARS-CoV-2-specific mAb therapy led to a height-ened host neutralizing antibody response to the mAb-resistant variant that was associated with eventual viral clearance. This demonstrates the interplay between the antiviral treatment-directed viral evolution and subsequent host immune response in viral clearance.
New scaling relations in cluster radio halos and the re-acceleration model

description: In this paper we derive new expected scaling relations for clusters with giant radio halos in the framework of the re-acceleration scenario in a simplified, but physically motivated, form, namely: radio power (P_R) vs size of the radio emitting region (R_H), and P_R vs total cluster mass (M_H) contained in the emitting region and cluster velocity dispersion (sigma_H) in this region. We search for these correlations by analyzing the most recent radio and X-ray data available in the literature for a well known sample of clusters with giant radio halos. In particular we find a good correlation between P_R and R_H and a very tight ``geometrical'' scaling between M_H and R_H. From these correlations P_R is also expected to scale with M_H and sigma_H and this is confirmed by our analysis. We show that all the observed trends can be well reconciled with expectations in the case of a slight variation of the mean magnetic field strength in the radio halo volume with M_H. A byproduct correlation between R_H and sigma_H is also found, and can be further tested by optical studies. In addition, we find that observationally R_H scales non-linearly with the virial radius of the host cluster, and this immediately means that the fraction of the cluster volume which is radio emitting increases with cluster mass and thus that the non-thermal component in clusters is not self-similar.

description: Deterministic solid-state quantum light sources are considered key building blocks for future communication networks. While several proof-of-principle experiments of quantum communication using such sources have been realized, most of them required large setups often involving liquid helium infrastructure or bulky closed-cycle cryotechnology. In this work, we report on the first quantum key distribution (QKD) testbed using a compact benchtop quantum dot single-photon source operating at telecom wavelengths. The plug\&play device emits single-photon pulses at O-band wavelengths ($1321\,$nm) and is based on a directly fiber-pigtailed deterministically-fabricated quantum dot device integrated into a compact Stirling cryocooler. The Stirling is housed in a 19-inch rack module including all accessories required for stand-alone operation. Implemented in a simple QKD testbed emulating the BB84 protocol with polarization coding, we achieve an antibunching of $g^{(2)}(0) = 0.10\pm0.01$ and a raw key rate of up to $(4.72\pm0.13)\,$kHz using an external pump laser. In this setting, we further evaluate the performance of our source in terms of the quantum bit error ratios, secure key rates, and tolerable losses expected in full implementations of QKD also accounting for finite key size effects. Furthermore, we investigate optimal settings for a two-dimensional temporal acceptance window applied on receiver side, resulting in predicted tolerable losses up to $23.19\,$dB. Not least, we compare our results with previous proof-of-concept QKD experiments using quantum dot single-photon sources. Our study represents an important step forward in the development of fiber-based quantum-secured communication networks exploiting sub-Poissonian quantum light sources.

description: Sexual minority men of color report intimate partner violence (IPV) and substance use at elevated rates compared to heterosexual peers, but little is known about how types (physical/sexual, controlling, monitoring, emotional) of perpetration and victimization are connected to types of substance use. Associations between past-6-month IPV experiences and substance use (tobacco, alcohol, cannabis, poppers, cocaine) were examined among sexual minority men (N = 414; 18–27 years). IPV victimization and perpetration were reported by 22% and 14% of the sample. Any victimization and controlling victimization were positively correlated with tobacco use, physical victimization was positively correlated with cocaine and poppers use, and monitoring victimization was negatively correlated with cannabis and poppers use. Any perpetration was positively correlated with tobacco use and binge drinking, and emotional perpetration was positively correlated with binge drinking. Understanding and addressing IPV victimization and perpetration experiences are critical for understanding risk conferred by IPV in this population.

Kennis neemt in belang toe: als basis voor ontwikkeling, voor groei en om de global challenges te kunnen aanpakken. Het wordt steeds belangrijker dat samenwerking uitgaat van samen kennis ontwikkelen en toepassen (niet uitsluitend overdragen), op basis van gelijkwaardigheid. Dat is in wederzijds belang ook als het gaat om lage en middeninkomenslanden. De Nederlandse ontwikkelingssamenwerking is veranderd. In het regeringsbeleid van de afgelopen jaren is de scope verbreed van hulp naar hulp en handel; aid and trade. De rol en de inzet van de kennisinstellingen is gaandeweg ook gewijzigd. In het licht van de ontwikkelingen willen de hogescholen en universiteiten daarom hun visie op dit onderwerp uiteenzetten. De wijze waarop individuele instellingen zich inzetten zal afhangen van hun eigen missie en profiel.

description: This study investigates the species richness and distribution of ladybird beetles (Coccinellidae) across various habitats on San Cristóbal Island in the Galápagos Archipelago, Ecuador. Through extensive field surveys, we catalogued nineteen species, including four previously known species (two endemics, Psyllobora bisigma and Scymnobius scalesius, and two natives, Cycloneda sanguinea and Tenuisvalvae bromelicola). We also identified nine possibly native species reported for the first time in the Galapagos islands in this study or correspond to the first voucher specimens for the island. We collected three previously reported non-native species: Cheilomenes sexmaculata, Novius cardinalis, and Paraneda guticollis. Three species belonging to the genera Stethorus, Calloeneis, and Delphastus remain undetermined, pending further taxonomic analyses. Our findings reveal a rich and complex community with notable differences in species abundance and habitat preference. Endemic species were found to be particularly scarce and restricted mainly to crops undergoing forest regeneration and deciduous forests, emphasising their vulnerability and specialised habitat requirements. The native Cycloneda sanguinea emerged as the most prevalent species, exhibiting broad ecological adaptability. Non-native species, like Cheilomenes sexmaculata, were predominantly found in disturbed habitats, with some showing early signs of spreading into more natural environments, raising concerns about their potential impact on local biodiversity. These findings contribute valuable knowledge to understanding Coccinellidae diversity on San Cristóbal Island and highlight the importance of continued monitoring, particularly in the face of ongoing environmental change and the introduction of non-native species. This study underscores the need for targeted conservation efforts to protect the unique and fragile ecosystems of the Galápagos Archipelago.
Clause repetition as a tying technique in Greek conversation

description: This chapter targets a language in which bridging constructions are not grammaticalized, that is, Greek. It examines instances of same-speaker and cross-speaker clause repetition in informal Greek conversation. The analysis demonstrates that the basic function of clause repetition is to display connectedness between what the current speaker says or does and what the same or previous speaker said or did immediately before. It is argued that clause repetition displays some similarities with recapitulative linkage and it is hypothesized that recapitulative linkage constructions have emerged from repetition practices in conversation.

description: Understanding the interplay between the HIV reservoir and the host immune system may yield insights into HIV persistence during antiretroviral therapy (ART) and inform strategies for a cure. Here, we applied machine learning (ML) approaches to cross-sectional high-parameter HIV reservoir and immunology data in order to characterize host-reservoir associations and generate new hypotheses about HIV reservoir biology. High-dimensional immunophenotyping, quantification of HIV-specific T cell responses, and measurement of genetically intact and total HIV proviral DNA frequencies were performed on peripheral blood samples from 115 people with HIV (PWH) on long-term ART. Analysis demonstrated that both intact and total proviral DNA frequencies were positively correlated with T cell activation and exhaustion. Years of ART and select bifunctional HIV-specific CD4 T cell responses were negatively correlated with the percentage of intact proviruses. A leave-one-covariate-out inference approach identified specific HIV reservoir and clinical-demographic parameters, such as age and biological sex, that were particularly important in predicting immunophenotypes. Overall, immune parameters were more strongly associated with total HIV proviral frequencies than intact proviral frequencies. Uniquely, however, expression of the IL-7 receptor alpha chain (CD127) on CD4 T cells was more strongly correlated with the intact reservoir. Unsupervised dimension reduction analysis identified two main clusters of PWH with distinct immune and reservoir characteristics. Using reservoir correlates identified in these initial analyses, decision tree methods were employed to visualize relationships among multiple immune and clinical-demographic parameters and the HIV reservoir. Finally, using random splits of our data as training-test sets, ML algorithms predicted with approximately 70% accuracy whether a given participant had qualitatively high or low levels of total or intact HIV DNA . The techniques described here may be useful for assessing global patterns within the increasingly high-dimensional data used in HIV reservoir and other studies of complex biology.

description: We derive the most general Seiberg-Witten maps for noncommutative gauge theories in second order of the noncommutative parameter theta. Our results reveal the existence of more ambiguities than previously known. In particular, we demonstrate that some of these ambiguities enter observables like scattering cross sections and enlarge the parameter space of the noncommutative standard model beyond O(theta).

description: This study examines heat exposure and its impact on the thermal comfort and health of spectators within a semi-outdoor American college football stadium in the southeastern United States. Over 50 sensors were deployed during the 2016 season from late August to late November to measure temperature and humidity across various stadium locations. Significant variations in temperature, heat index, and a modified version of the physiological equivalent temperature (mPET) were found within the stadium, with some areas exceeding National Weather Service heat alert thresholds during certain games. Moreover, mean temperatures in the stadium were higher than those measured at a nearby weather station, while the mean heat index was higher in the seating areas than in other stadium locations and at the nearby weather station. Reductions in modeled wind speed resulted in significant decreases in thermal comfort and greater physical stress among spectators, particularly when the wind was calm. Heat-related illness comprised up to two-thirds of all cases treated by first aid and emergency medical services during particularly hot games. Most of these occurred in the most thermally oppressive parts of the stadium. These results highlight the need for greater monitoring of heat exposure inside stadiums, earlier implementation of heat action plans to raise awareness and educate spectators on heat mitigation strategies, and incorporation of stadium design modifications that improve circulation, increase shade, and reduce crowding.

description: We report the serendipitous findings of 13 faint meteors and 44 artificial space objects by Subaru SuprimeCam imaging observations during 11-16 August 2004. The meteors, at about 100km altitude, and artificial satellites/debris in orbit, at 500km altitude or higher, were clearly discriminated by their apparent defocused image sizes. CCD photometry of the 13 meteors, including 1 Perseid, 1 Aquarid, and 11 sporadic meteors, was performed. We defined a peak video-rate magnitude by comparing the integrated photon counts from the brightest portion of the track traversed within 33ms to those from a 0-mag star during the same time duration. This definition gives magnitudes in the range 4.0< V_{vr} <6.4 and 4.1< I_{vr}<5.9 for these 13 meteors. The corresponding magnitude for virtual naked-eye observers could be somewhat fainter especially for the V-band observation, in which the [OI] 5577 line lasting about 1 sec as an afterglow could contribute to the integrated flux of the present 5-10 min CCD exposures. Although the spatial resolution is insufficient to resolve the source size of anything smaller than about 1 m, we developed a new estimate of the collisionally excited column diameter of these meteors. A diameter as small as a few mm was derived from their collisionally excited photon rates, meteor speed, and the volume density of the oxygen atoms at the 100km altitude. The actual column diameter of the radiating zone, however, could be as large as few 100m because the excited atoms travel that distance before they emit forbidden lines in 0.7 sec of its average lifetime. Among the 44 artificial space objects, we confirmed that 17 were cataloged satellites/space debris.

description: Myocardial infarction (MI) is a leading cause of mortality globally and is predominantly attributed to coronary artery disease (CAD). MI is categorized as ST-elevation MI (STEMI) or non-ST-elevation MI (NSTEMI), each with distinct etiologies and treatment pathways. The goal in treatment for both is restoring blood flow back to the myocardium. STEMI, characterized by complete occlusion of a coronary artery, is managed urgently with reperfusion therapy, typically percutaneous coronary intervention (PCI). In contrast, NSTEMI involves a partial occlusion of a coronary artery and is treated with medical management, PCI, or coronary artery bypass grafting (CABG) depending on risk scores and clinical judgment. The Heart Team approach can assist in deciding which reperfusion technique would provide the greatest benefit to the patient and is especially useful in complicated cases. Despite advances in treatment, complications such as cardiogenic shock (CS) and ischemic heart failure (HF) remain significant. While percutaneous coronary intervention (PCI) is considered the primary treatment for MI, it is important to recognize the significance of cardiac surgery in treatment, especially when there is complex disease or MI-related complications. This comprehensive review analyzes the role of cardiac surgery in MI management, recognizing when it is useful, or not.

description: Unsustained matter distributions unescapely collapse unless fragmentation and centrifugal or pressure support take place. Starting from the above evidence, supermassive compact objects at the centre of large-mass galaxies are conceived as the end-product of the gravitational collapse of local density maxima around which overdensities are located. At the beginning of evolution, local density maxima are idealized as homogeneous peaks, while the surrounding envelopes are described by a power-law density profile. The dependence of the density profile on a second parameter, chosen to be the ratio between peak and total mass, is analysed. Overdensity evolution is discussed in the context of quintessence cosmological models and further investigation is devoted to a special case with the aim to describe the central collapse. An empirical relation between hole and dark halo mass is translated into a dependence of the fractional hole mass on the overdensity mass. Computations are performed up to the end of central collapse, and density profiles of related configurations are determined together with additional parameters. The central collapse is completed in early times, no longer than a few hundredths of Gyr, which implies hole formation when proto-haloes, proto-bulges, and proto-disks are still expanding or contracting. No appreciable change in evolution is found with regard to different mean peak heights related to equal masses. On the other hand, it is recognized that homogeneous peaks collapse ``faster'' with respect to surroundings envelopes, in low-mass than in large-mass overdensities. In conclusion, it is inferred that gravitational collapse of homogeneous peaks within overdensities may be a viable mechanism for hole generation.

description: Consider n=2l>=4 point particles with equal masses in space, subject to the following symmetry constraint: at each instant they form an orbit of the dihedral group D_l, where D_l is the group of order 2l generated by two rotations of angle pi around two secant lines in space meeting at an angle of pi/l. By adding a homogeneous gravitational (Newtonian) potential one finds a special $n$-body problem with three degrees of freedom, which is a kind of generalisation of Devaney isosceles problem, in which all orbits have zero angular momentum. In the paper we find all the central configurations and we compute the dimension of the stable/unstable manifolds.
