Photon Bunching at TeV Energies

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Harwit, Protheroe, and Biermann (1999) recently proposed that Bose-Einstein photon bunching might significantly affect the interpretation of Cerenkov counts of TeV gamma photons. Here, we show that a combination of two recent results of Aharonian et al. (2000) and Aharonian et al. (2001) permits us to set new, more stringent upper limits of $\lesssim 10%$ on the fractional amount of photon bunching in the 7-10 TeV radiation from Markarian 501. Potential bunching at even higher energies should nevertheless continue to be investigated for this and other TeV sources, since a clear understanding of TeV energy spectra is required to unambiguously determine the spectral energy density of the mid-infrared extragalactic background.

description: This article aims to analyse the use of qualitative methods by students in carrying out their studies at Iqra Buru
University, then explained about information, reason, and the orientation they have about qualitative methods. The
approach used in this study is descriptive qualitative, by using interviews as a data collection model and data analysis techniques in the form of textual analysis techniques from the results of field note transcripts. Results from the field show the theoretical information of the qualitative methods possessed by informants is still low causing reasons for use because the field of science is studied, while the orientation of informants prioritizes the use of qualitative methods to complete the final task. Conclusions from field studies show that the use of qualitative methods is still considered
a complement in the completion of the informant's study, so it is difficult to get research results that have contributed
to the development of qualitative methods.

description: Oligoryzomys Bangs, 1900   Pygmy rice rats
 The pygmy rice rats are a speciose but poorly known group that is widely distributed throughout the Neotropical Realm, from southern México to Tierra del Fuego and to eastern Amazonia and the Mata Atlântica of coastal Brazil (Carleton and Musser, 1989; Emmons and Feer, 1997). Over this enormous range, member species may be common within habitats spanning lowland tropical forest to the high Andean puna grasslands or páramo above timberline. Often placed as a subgenus within Oryzomys by earlier workers, its generic status was solidified by Carleton and Musser (1989), who provide an emended diagnosis as well as a provisional list of species with generalized descriptions and geographic ranges. Their diagnosis includes, but is not limited to, the following traits: small body size; tail usually longer than head and body; six plantar tubercles, with hypothenar pad small and round; skull small but stout in appearance; rostrum relatively broad and stocky; interorbital region hourglass shaped with squared edges; braincase elongate, smooth, and flat, with foramen magnum directed posteriorly; zygomatic arches bowed laterally; jugal reduced or absent; zygomatic notches distinct; zygomatic plates broad, with the anterior edge reaching the nasolacrimal capsules; stapedial foramen large, posterior opening of alisphenoid canal large, squamosal­alisphenoid groove and sphenofrontal foramen absent (derived cephalic arterial supply; pattern 2 of Voss, 1988; Carleton and Musser, 1989); incisors opisthodont, asulcate; molars brachydont, cuspidate, with three roots in uppers and two in lowers; first molars ovate, anteromedian flexus (­id) shallow, anterolabial and anterolingual conules (­ids) small, anteroloph and mesoloph (­id) present; anterolabial cingulum well developed on lower third molar.

description: Transfer reinforcement learning (RL) aims at improving the learning efficiency of an agent by exploiting knowledge from other source agents trained on relevant tasks. However, it remains challenging to transfer knowledge between different environmental dynamics without having access to the source environments. In this work, we explore a new challenge in transfer RL, where only a set of source policies collected under diverse unknown dynamics is available for learning a target task efficiently. To address this problem, the proposed approach, MULTI-source POLicy AggRegation (MULTIPOLAR), comprises two key techniques. We learn to aggregate the actions provided by the source policies adaptively to maximize the target task performance. Meanwhile, we learn an auxiliary network that predicts residuals around the aggregated actions, which ensures the target policy's expressiveness even when some of the source policies perform poorly. We demonstrated the effectiveness of MULTIPOLAR through an extensive experimental evaluation across six simulated environments ranging from classic control problems to challenging robotics simulations, under both continuous and discrete action spaces. The demo videos and code are available on the project webpage: https://omron-sinicx.github.io/multipolar/.

title: Exploring the Lived Experiences of Students in Work Integrated Learning (WIL) Team Project: A Descriptive Phenomenological Approach
Creators: name: Bolinas, Julius Cesar F

Subjects: subject: work-integrated learning (WIL)

subject: student experience

description: The transition from academia to professional life is critical for students, necessitating an effective approach to enhance their employability. Work integrated learning (WIL) is one approach that is embedded by higher education institutions (HEIs) in their curricula so students can work on industry projects where they can apply their theoretical and practical knowledge in a safe and constructive environment. The importance of WIL in enhancing students' employability has come into focus because of industry demands and expectations from the HEIs to turn out work-ready graduates. Because of this, WIL is recognised as an essential part of students' university experience to prepare them to meet industry expectations. Despite its significance, most research on WIL is industryoriented, lacking a student-centred perspective. This study aims to fill this gap by inquiring into the students' lived experiences in WIL to understand their needs based on their personal circumstances and learning proclivities. The research question of this study is: What are the students' lived experiences in the work integrated learning (WIL) Team Project? Using a descriptive phenomenological approach, the lived experiences of 13 students from the Griffith University School of ICT engaged in a WIL Team Project were explored. Data collected via contextual interviews was processed using Giorgi's phenomenological method and further examined through Ilgen's input-mediator-output-input (IMOI) framework and a design literacy conceptual framework. The findings reveal five major themes that described the stages of the students' lived experiences in the work integrated learning (WIL) Team Project: Stage 1: Limiting options and challenging self-confidence, Stage 2: Accepting behaviours and coping responses, Stage 3: Valuing the WIL Team Project stream, Stage 4: Working with others and dealing with challenges, and Stage 5: Problem-solving. Additionally, the advent and acceptance of virtuality in WIL, particularly during Covid-19 restrictions, were recognised. With the aim of informing the design of WIL, this study contributes to understanding student perspectives on WIL and augmenting the limited literature from a student-centred perspective, informing pedagogies in higher education like learning-by-doing and experiential learning, as well as the cross disciplinary fields of User-experience research, Experience Design, and Human-Computer Interaction. The results suggest that the combination of theory, practice, and virtual collaboration in WIL is instrumental in promoting students' professional identity and employability skills.

Oryzomys nitidus

description: Oryzomys nitidus (Thomas, 1884)
TYPE LOCALITY: Valley of Río Tulumayo, 10 km south of San Ramón, Amable María, 2000 ft, Departamento de Junín, Perú (as located by Gardner and Patton, 1976).
DESCRIPTION: See above, figures 95 and 96, and tables 38 and 40.
SELECTED MEASUREMENTS: See table 39.
 DISTRIBUTION AND HABITAT: This species is widely distributed through the western margins of Amazonia, from Perú south through Bolivia, western and south­central Brazil, eastern Paraguay, and northeastern Argentina (Musser et al., 1998). As noted by these authors, O. nitidus is apparently absent from the ‘‘vast core of the Amazon Basin’’ (p. 187). In our survey of the Rio Jurua´, we obtained specimens of this species only in terra firme forest and at only one locality, Igarapé Porongaba (locality 1) in the Headwaters Region. The six specimens collected were all taken in Sherman traps set on the ground. At this locality, O. nitidus was sympatric with both O. perenensis and O. yunganus.
REPRODUCTION: We captured specimens only during the month of February. Three adult males had scrotal testes and enlarged vesicular glands (16 to 17 mm long) indicative of reproductive activity. Of the two adult females, one was pregnant with 5 embryos and the second was parous but neither pregnant nor lactating. A single nonreproductive young female (age class 1) was in sparse reddish juvenile pelage.
KARYOTYPE: 2n = 80, FN = 86. The chromosomal complements from two males (MNFS 1147 and 1419) and two females (MNFS 1223 and 1420) are identical to each other and the same as those reported by Gardner and Patton (1976) for samples from several localities in eastern Peru´. The autosomes consist of 35 pairs of acrocentrics, one distinctly large and the remainder graded from large to small, and four pairs of small metacentrics; the sex chromosomes are a large subtelocentric X and a small acrocentric Y.
 SPECIMENS EXAMINED (n = 6): (1) 3 m, 3 f — MNFS 1147, 1208, 1223, 1310, 1419– 1420.

description: Changing climate and its interactions with catchments may result in changes to water resources. This study examines the temporal trends in streamflow across New South Wales, Australia. Across 105 catchments with over 35 years of records up to September 2020, we used Mann-Kendall and Sen’s Slope methods to estimate trends in different flow indicators, including the annual, low and high flows, cease to flow, and the rainfall-–runoff relationship. Nearly all (104) catchments have decreasing trends in annual flow, with 32 of these being statistically significant, indicating an overall drying pattern. Most declines are 10–20% per decade relative to the mean annual flows of individual catchments. Trends in rainfall-–runoff relationship suggest that the flow declines are generally greater than expected with given rainfall, and likely due to region-scale processes such as groundwater and vegetation dynamics. Our finding has important implications for future water security for New South Wales and similar environments, such as planning for future reduction in water resources availability with likely increasing demands.

description: Understanding the properties of the hot corona is very important for studying the accretion disks in black hole X-ray binary systems. Using the Monte-Carlo technique to simulate the inverse Compton scattering process between disk photons and electrons in the hot corona, we have produced two table models in the XSPEC package. Applying the models to the broad-band BeppoSAX observations of the black hole candidate XTE J2012+381, we demonstrate the power of this table model. Our results indicate that the electron distribution in the corona has a powerlaw shape with a spectral index around 4 and the size of the corona is just several tens of gravitational radius and the inclination angle of the disk is around 60 degrees.

description: The isolated neutron star RX J0806.4-4123 was observed with XMM-Newton in November 2000. The data from the three EPIC instruments allowed us (i) to derive an improved X-ray position to an accuracy of 2-3'', (ii) to accumulate the first medium-resolution soft X-ray spectra of high statistical quality and (iii) to find a candidate for the neutron star rotation period. Although this period of 11.3714 s is formally detected at a 3.5-σlevel in the EPIC-pn data, the similar pulse profiles deduced from all three EPIC instruments increase the confidence that the period is real. The pulsed fraction of ~6% would then be the weakest X-ray flux modulation detected from dim isolated neutron stars. We fitted the X-ray spectra with blackbody and neutron star atmosphere models and discuss the results with respect to the brightness limit placed by optical images. The reduced size of the error circle on the X-ray position should allow deeper searches for an optical counterpart.

description: A subgroup $H\leq G$ is said to be almost normal if every conjugate of $H$ is commensurable to $H$. If $H$ is almost normal, there is a well-defined quotient space $G/H$. We show that if a group $G$ has type $F_{n+1}$ and contains an almost normal coarse $PD_n$ subgroup $H$ with $e(G/H)=\infty$, then whenever $G'$ is quasi-isometric to $G$, it contains an almost normal subgroup $H'$ that is quasi-isometric to $H$. Moreover, the quotient spaces $G/H$ and $G'/H'$ are quasi-isometric. This generalises a theorem of Mosher-Sageev-Whyte, who prove the case in which $G/H$ is quasi-isometric to a finite valence bushy tree. Using work of Mosher, we generalise a result of Farb-Mosher to show that for many surface group extensions $Γ_L$, any group quasi-isometric to $Γ_L$ is virtually isomorphic to $Γ_L$. We also prove quasi-isometric rigidity for the class of finitely presented $\mathbb{Z}$-by-($\infty$ ended) groups.

description: During the 2007-09 recession, inflation-adjusted food expenditures by U.S. households fell 5 percent—the largest decrease in at least 25 years. Spending patterns differed by income level, with middle-income households curbing expenditures the most. Households responded to the recession by cutting back on eating out and by economizing on grocery purchases.

description: In loop quantum cosmology, the values of volume fluctuations and correlations determine whether the dynamics of an evolving state exhibits a bounce. Of particular interest are states that are supported only on either the positive or the negative part of the spectrum of the Hamiltonian that generates this evolution. It is shown here that the restricted support on the spectrum does not significantly limit the possible values of volume fluctuations.

description: Spectroscopic studies of high-redshift objects and increasingly precise data on the cosmic microwave background (CMB) are beginning to independently place strong complementary bounds on the epoch of hydrogen reionization. Parameter estimation from current CMB data continues, however, to be subject to several degeneracies. Here, we focus on those degeneracies in CMB parameter forecasts related to the optical depth to reionization. We extend earlier work on the mutual constraints that such analyses of CMB data and a reionization model may place on each other to a more general parameter set, and to the case of data anticipated from the $MAP$ satellite. We focus in particular on a semi-analytic model of reionization by the first stars, although the methods here are easily extended to other reionization scenarios. A reionization model can provide useful complementary information for cosmological parameter (CP) extraction from the CMB, particularly for the degeneracies between the optical depth and either of the amplitude and index of the primordial scalar power spectrum, which are still present in the most recent data. Alternatively, by using a reionization model, known limits on astrophysical quantities can reduce the forecasted errors on CPs. Forthcoming CMB data also have the potential to constrain the sites of early star formation, as well as the fraction of baryons that participate in it. Finally, we examine the implications of an independent, e.g., spectroscopic, determination of the epoch of reionization for the determination of CPs from the CMB. This has the potential to significantly strengthen limits from the CMB on parameters such as the index of the power spectrum, while having the considerable advantage of being free of the choice of the reionization model (abridged).

description: Thermal expansion of α-rhombohedral boron (α-B12) and two isostructural boron-rich pnictides (B12P2 and B12As2) has been studied between 298 and 1280 K by high-temperature synchrotron X-ray diffraction. For all studied phases no temperature-induced phase transitions have been observed. The observed temperature dependencies of the lattice parameters and unit cell volumes were found to be quasi-linear. Variation of the thermal expansion coefficients in the group of boron-rich pnictides (B13N2 - B12P2 - B12As2) was analyzed.

Subjects: Demand and Price Analysis

description: Large and rapid increases have occurred for many food commodity prices during 2010-11. Long-term production and consumption trends underlay rising food commodity prices, but worldwide production shortfalls and changes in trade policies and practices in a number of countries sparked the sharp surge in prices after June 2010. Many of the long-term trends and short-run shocks contributing to the current price surge also played a role in previous price spikes.
Fisher information in confined isotropic harmonic oscillator

description: Fisher information ($I$) is investigated in a confined harmonic oscillator (CHO) enclosed in a spherical enclosure, in conjugate $r$ and $p$ spaces. A comparative study between CHO and a free quantum particle in spherical box (PISB), as well as CHO and respective free harmonic oscillator (FHO) is pursued with respect to energy spectrum and $I$. This reveals that, a CHO offers two exactly solvable limits, namely, a PISB and an FHO. Moreover, the dependence of $I$ on quantum numbers $n_{r}, l, m$ in FHO and CHO are analogous. The role of force constant is discussed. Further, a thorough systematic analysis of $I$ with respect to variation of confinement radius $r_c$ is presented, with particular attention on \emph{non-zero}-$(l,m)$ states. Considerable new important observations are recorded. The results are quite accurate and most of these are presented for the first time.

description: The generation of regular and irregular inflected verb-forms has been taken as a crucial test between models of inﬂection in the mental lexicon, namely approaches which invoke different mechanisms for regular and irregular forms (rule-based procedures vs. recovery of whole forms stored in an associative network) and accounts which postulate a single procedure for all forms. An alternative hypothesis suggests that inflectional processes are explained by membership of words to clusters, for instance, Italian inflectional classes (conjugations). In a behavioural and a rapid event-related fMRI experiment, participants overtly generated the past participle of verbs from the three Italian conjugations. Results showed that the cognitive operations and the neural substrate underlying inflectional processes rely on specific properties of inflectional classes. Different patterns of cortical activations elicited by verbs from different conjugations were detected for the first time in the left middle frontal gyrus, left pre-supplementary motor area and left anterior cingulate cortex.

description: Simulated with small environmental chambers, the emission characteristics of total volatile organic compounds from plastic runway surfaces were investigated by thermal desorption–gas chromatography–mass spectrometry. This quantitative approach was validated using a dynamic recovery experiment, and the variation of emission factors from mixed-type plastic surfaces was determined. Also, the photodegradation of volatile organic compounds in chambers was introduced to decrease the background interference.

description: The preference of the human parser for interpreting syntactically ambiguous sentence-initial arguments as the subject of a clause (i.e. subject preference) has been documented for spoken and sign languages. Recent research (He, 2016) suggests that the subject preference can be eliminated by manipulating information structure (topicalisation). To investigate the effects of interaction between syntax and information structure on language processing, we tested the role of topic marking in sentence processing in Austrian Sign Language (ÖGS). We examined whether non-manual topic marking on the sentence-initial argument eliminates the subject preference using event-related brain potentials. We replicated the finding of the subject preference in ÖGS by identifying an N400-family response to object-first sentences. Further, topic marking in ÖGS influenced the processing of the topic argument itself and later processing stages. This suggests that interpretation of topic marking imposes additional processing costs, relative to syntactic reanalysis.

description: Sr2RuO4 is at present the best candidate for being a superconducting analogue of the triplet superfluidity in ^3He. This material is a good (albeit correlated) Fermi liquid in the normal state and an exotic superconductor below Tc. The mechanism of superconductivity and symmetry of the order parameter are the main puzzling issues of on-going research. Here we present the results of our search for a viable description of the superconducting state realised in this material. Our calculations are based on a three-dimensional effective three-band model with a realistic band structure. We have found a state with non-zero order parameter on each of the three sheets of the Fermi surface. The corresponding gap in the quasi-particle spectrum has line or point nodes on the alpha and beta sheets and is complex with no nodes on the gamma sheet. This state describes remarkably well a number of existing experiments including power low temperature dependence of the specific heat, penetration depth, thermal conductivity etc. The stability of the state with respect to disorder and different interaction parameters are also analyzed briefly.

description: Measuring the photoluminescence of defects in crystals is a common experimental technique for analysis and identification. However, current theoretical simulations typically require the simulation of a large number of atoms to eliminate finite size effects, which discourages computationally expensive excited state methods. We show how to extract the room-temperature photoluminescence spectra of defect centres in bulk from an $\mathrm{\textit{ab-initio}}$ simulation of a defect in small clusters. The finite size effect of small clusters manifests as strong coupling to low frequency vibrational modes. We find that removing vibrations below a cutoff frequency determined by constrained optimization returns the main features of the solid state photoluminescence spectrum. This strategy is illustrated for an NV$^{-}$ defect in diamond, presenting a connection between defects in solid state and clusters; the first vibrationally resolved $\mathrm{\textit{ab-initio}}$ photoluminescence spectrum of an NV$^{-}$ defect in a nanodiamond; and an alternative technique for simulating photoluminescence for solid state defects utilizing more accurate excited state methods.

description: Future cellular networks will be dense and require key traffic management technologies for fine-grained network control. The problem gets more complicated in the presence of different network segments with bottleneck links limiting the desired quality of service (QoS) delivery to the last mile user. In this work, we first design a framework for software-defined cellular networks (SDCN) and then propose new mechanisms for management of QoS and non-QoS users traffic considering both access and backhaul networks, jointly. The overall SDN-LTE system and related approaches are developed and tested using network simulator (ns-3) in different network environments. Especially, when the users are non-uniformly distributed, the results shows that compared to other approaches, the proposed load distribution algorithm enables at least 6\% and 23\% increase in the average QoS user downlink (DL) throughput for all network users and 40\%-ile edge users, respectively. Also, the proposed system efficiently achieves desired QoS and handles the network congestion without incurring significant overhead.

description: Eurasian beaver (Castor fiber) reintroduction is taking place in England with potential benefits for flood alleviation and biodiversity; however there is also opposition. One area of controversy relates to fish and fishing. A previous meta-analysis of research into beaver-fish relationships found perceived benefits of beavers amongst fish and beaver “experts” included increased fish abundance and productivity, whilst perceived negatives included impeded fish passage and reduced spawning habitat availability. We further this understanding using Q-Methodology (a social science technique) to reveal three nuanced and contrasting perspectives that exist amongst the angling community in the catchment of a trial reintroduction. Due to a conflict potential between groups, we suggest management themes to help reduce this where reintroduction occurs: open, cross-sectoral dialogue about research into beaver-fish relationships and management; a management strategy which supports ecosystem benefits whilst providing a sense of empowerment for individuals to respond to negative impacts.
