description: We develop the theory of an Andreev junction, which provides a method to probe the intrinsic topology of the Fermi sea of a two-dimensional electron gas (2DEG). An Andreev junction is a Josephson $π$ junction proximitizing a ballistic 2DEG, and exhibits low-energy Andreev bound states that propagate $\textit{along}$ the junction. It has been shown that measuring the nonlocal Landauer conductance due to these Andreev modes in a narrow linear junction leads to a topological Andreev rectification (TAR) effect characterized by a quantized conductance that is sensitive to the Euler characteristic $χ_F$ of the 2DEG Fermi sea. Here we expand on that analysis and consider more realistic device geometries that go beyond the narrow linear junction and fully adiabatic limits considered earlier. Wider junctions exhibit additional Andreev modes that contribute to the transport and degrade the quantization of the conductance. Nonetheless, we show that an appropriately defined $\textit{rectified conductance}$ remains robustly quantized provided large momentum scattering is suppressed. We verify and demonstrate these predictions by performing extensive numerical simulations of realistic device geometries. We introduce a simple model system that demonstrates the robustness of the rectified conductance for wide linear junctions as well as point contacts, even when the nonlocal conductance is not quantized. Motivated by recent experimental advances, we model devices in specific materials, including InAs quantum wells, as well as monolayer and bilayer graphene. These studies indicate that for sufficiently ballistic samples observation of the TAR effect should be within experimental reach.

description: Missing data is ubiquitous in hydrology. This phenomenon poses difficulty in the development of data-driven models. Events of missing data in groundwater pollution monitoring networks may occur due to failure of recording devices, malfunctioning of sensors, etc. Handling such missing data implies filling the missing portions of the data structure. Though several studies are available for dealing with missing data in the field of hydrology, literature dealing with such scenarios in groundwater pollution prediction is scarce. This paper assesses four imputation techniques – viz. linear, cubic spline, piece-wise cubic Hermite and modified Akima with cubic Hermite interpolation methods – for developing groundwater pollution prediction models using artificial neural network (ANN). The study employs the development of cascade-forward back-propagation ANN models using missing data ranging from 5% to 75% and evaluating their performance. Results show that imputation techniques can be effective in such circumstances.

description: We consider the problem of clustering partially labeled data from a minimal number of randomly chosen pairwise comparisons between the items. We introduce an efficient local algorithm based on a power iteration of the non-backtracking operator and study its performance on a simple model. For the case of two clusters, we give bounds on the classification error and show that a small error can be achieved from $O(n)$ randomly chosen measurements, where $n$ is the number of items in the dataset. Our algorithm is therefore efficient both in terms of time and space complexities. We also investigate numerically the performance of the algorithm on synthetic and real world data.

Glocalizing K-Pop: Pinoy Pop and Thai Pop Music as Glocal Expressions of Evolving Cultural Identities in the ASEAN
Creators: name: Engaño, Pamela Mae
Publisher: name: Zenodo
Year: 2022
Subjects: ASEAN, K-Pop Glocalization, Decolonization, Regionalization, Cultural Identities

description: This study examines how today’s in-demand K-Pop-inspired Pinoy Pop (P-Pop) groups Alamat and SB19, Thai-Pop (T-Pop) groups 4MIX and Vyra, and their talent companies approach K-Pop glocalization to reinvent their own doses of pop music that represent glocal cultural identities different from that of K-Pop music idols. Framed after music glocalization, music-and-identity construction, and regionalization concepts, this study uses an ethnographic research design to analyze how P-Pop and T-Pop groups and their talent companies glocalize the K-Pop idol formula in producing their selected hit singles; employs contextual analysis to understand how historical, sociocultural, and political drivers shape their glocalization techniques; and, triangulates said drivers with subjects’ music-making experiences to paint a picture of their cultural identities as reflected in their selected P-Pop and T-Pop songs. Findings show that P-Pop and T-Pop groups and their talent companies differently approach K-Pop glocalization from the moment would-be idols were scouted, trained, and groomed down to their debut and participation in the music-making process. Moreover, the experiences and words put together to create subjects’ hit singles speak of the historical, sociocultural, and political shifts the Filipino and Thai societies and their local music industries have gone through. More than just affirming the cultural diverseness of the Philippines and Thailand, subjects’ varying glocalization techniques reinforce P-Pop and T-Pop music as modern-day expressions of local genius rather than mere imitation. With K-Pop glocalization advancing decolonization and regionalization in the Association of Southeast Asian Nations (ASEAN), P-Pop and T-Pop music along with other ASEAN member-states’ doses of pop music, if provided with thriving space outside their countries, can serve as catalysts that further facilitate Aseanization and community building in the region.

description: We study a modified record process where the $k$'th record in a series of independent and identically distributed random variables is defined recursively through the condition $Y_k > Y_{k-1} - δ_{k-1}$ with a deterministic sequence $δ_k > 0$ called the handicap. For constant $δ_k \equiv δ$ and exponentially distributed random variables it has been shown in previous work that the process displays a phase transition as a function of $δ$ between a normal phase where the mean record value increases indefinitely and a stationary phase where the mean record value remains bounded and a finite fraction of all entries are records (Park \textit{et al} 2015 {\it Phys. Rev.} E \textbf{91} 042707). Here we explore the behavior for general probability distributions and decreasing and increasing sequences $δ_k$, focusing in particular on the case when $δ_k$ matches the typical spacing between subsequent records in the underlying simple record process without handicap. We find that a continuous phase transition occurs only in the exponential case, but a novel kind of first order transition emerges when $δ_k$ is increasing. The problem is partly motivated by the dynamics of evolutionary adaptation in biological fitness landscapes, where $δ_k$ corresponds to the change of the deterministic fitness component after $k$ mutational steps. The results for the record process are used to compute the mean number of steps that a population performs in such a landscape before being trapped at a local fitness maximum.

description: Nowadays, many extrasolar planetary systems possessing at least one planet on a highly eccentric orbit have been discovered. In this work, we study the possible long-term stability of such systems. We consider the general three body problem as our model. Highly eccentric orbits are out of the Hill stability regions. However, mean motion resonances can provide phase protection and orbits with long-term stability exist. We construct maps of dynamical stability based on the computation of chaotic indicators and we figure out regions in phase space, where the long-term stability is guaranteed. We focus on regions where at least one planet is highly eccentric and attempt to associate them with the existence of stable periodic orbits. The values of the orbital elements, which are derived from observational data, are often given with very large deviations. Generally, phase space regions of high eccentricities are narrow and thus, our dynamical analysis may restrict considerably the valid domain of the system's location.

description: [Objective] To study the characteristics of bryophytes in subalpine cold zone and related transition zone. [Method] The study was divided into scale A and scale B. On the scale of A, specimens were collected from Tongmai-Pailong-Dongjiu-Lulang-Sejila Pass-Nyingchi Town-Bagi Village along the national Highway 318. A sample plot was set for each 100 m altitude increase, and samples were collected between each two sample plots as well. On the scale of B, bryophyte specimens were collected and studied in the fixed sample plot of the Tibetan Nyingchi Alpine forest Ecosystem Research Observatory. [Result] Through the sampling and collection of bryophytes in Sejila Mountain, more than 3 000 specimens were identified with the classical classification method. There were 216 species of bryophytes belonging to 82 genera and 24 families. The bryophytes in the study area differed obviously in different vegetation types and slopes. The species richness of Sabina saltuaria-Abiesgeorgei var. smithii forest was the highest. The α diversity of Abiesgeorgei var. smithii forest was the highest, followed by Sabina saltuaria-Rhododendron forest, and that of alpine shrub was the lowest. Diversity studies showed that the β diversity of Sabina saltuaria-Rhododendron forest and Rhododendron forest on the eastern slope was the largest, and those of alpine shrub and Sabina saltuaria-Abiesgeorgei var. smithii forest were the lowest. However, the β diversity of Abiesgeorgei var. smithii forest on the western slope was the highest, and those of alpine shrub and Abiesgeorgei var. smithii forest were the lowest. [Conclusion] There are obvious differences in the distribution of bryophytes on the eastern and western slopes of Sejila Mountain of Tibet.

description: Deriving the Einstein field equations (EFE) with matter fluid from the action principle is not straightforward, because mass conservation must be added as an additional constraint to make rest-frame mass density variable in reaction to metric variation. This can be avoided by introducing a constraint $δ(\sqrt{-g}) = 0$ to metric variations $δg^{μν}$, and then the cosmological constant $Λ$ emerges as an integration constant. This is a removal of one of the four constraints on initial conditions forced by EFE at the birth of the universe, and it may imply that EFE are unnecessarily restrictive about initial conditions. I then adopt a principle that the theory of gravity should be able to solve time evolution starting from arbitrary inhomogeneous initial conditions about spacetime and matter. The equations of gravitational fields satisfying this principle are obtained, by setting four auxiliary constraints on $δg^{μν}$ to extract six degrees of freedom for gravity. The cost of achieving this is a loss of general covariance, but these equations constitute a consistent theory if they hold in the special coordinate systems that can be uniquely specified with respect to the initial space-like hypersurface when the universe was born. This theory predicts that gravity is described by EFE with non-zero $Λ$ in a homogeneous patch of the universe created by inflation, but $Λ$ changes continuously across different patches. Then both the smallness and coincidence problems of the cosmological constant are solved by the anthropic argument. This is just a result of inhomogeneous initial conditions, not requiring any change of the fundamental physical laws in different patches.

description: Designing reservoir outlets is a challenging subject in flood management among water resource managers. However, although several kinds of research are dedicated to flood mitigation strategies, rare studies exist in the literature considering flood uncertainties in reservoir outlet designs. This study fills this knowledge gap by developing a MATLAB® Toolbox application, entitled Release Allocation and Weir Design (RAWD), based on MATLAB® App Designer to obtain optimum reservoirs outlet design for effective flood management considering four outlets types, including an orifice as well as a proportional, a triangular, and a rectangular weir. The RAWD application handles uncertainties using non-linear interval number programming (NINP) and conditional value-at-risk (CVaR) approaches within an optimization model. Results show that the RAWD Toolbox application’s user can effectively and accurately meet downstream water demands and minimize water allocation shortages during the flood for a reservoir subjected to different shapes of inflow hydrographs.

description: We revisit stellar energy-loss bounds on the Yukawa couplings $g_{\rm B,L}$ of baryophilic and leptophilic scalars $ϕ$. The white-dwarf luminosity function yields $g_{\rm B}\lesssim 7 \times 10^{-13}$ and $g_{\rm L}\lesssim 4 \times 10^{-16}$, based on bremsstrahlung from ${}^{12}{\rm C}$ and ${}^{16}{\rm O}$ collisions with electrons. In models with a Higgs portal, this also implies a bound on the scalar-Higgs mixing angle $\sin θ\lesssim 2 \times 10^{-10}$. Our new bounds apply for $m_ϕ\lesssim {\rm 1~keV}$ and are among the most restrictive ones, whereas for $m_ϕ\lesssim 0.5\,{\rm eV}$ long-range force measurements dominate. Besides a detailed calculation of the bremsstrahlung rate for degenerate and semi-relativistic electrons, we prove with a simple argument that non-relativistic bremsstrahlung by the heavy partner is suppressed relative to that by the light one by their squared-mass ratio. This large reduction was overlooked in previous much stronger bounds on $g_{\rm B}$. In an Appendix, we provide fitting formulas (few percent precision) for the bremsstrahlung emission of baryophilic and leptophilic scalars as well as axions for white-dwarf conditions, i.e., degenerate, semi-relativistic electrons and ion-ion correlations in the ``liquid'' phase.

description: Understanding the behavior of light in non-equilibrium scenarios underpins much of quantum optics and optical physics. While lasers provide a severe example of a non-equilibrium problem, recent interests in the near-equilibrium physics of so-called photon `gases', such as in Bose condensation of light or in attempts to make photonic quantum simulators, suggest one re-examine some near-equilibrium cases. Here we consider how a sinusoidal parametric coupling between two semi-infinite photonic transmission lines leads to the creation and flow of photons between the two lines. Our approach provides a photonic analog to the Landauer transport formula, and using non-equilbrium Green's functions, we can extend it to the case of an interacting region between two photonic `leads' where the sinusoid frequency plays the role of a voltage bias. Crucially, we identify both the mathematical framework and the physical regime in which photonic transport is directly analogous to electronic transport and regimes in which other behavior such as two-mode squeezing can emerge.

description: Among Greek philosophers and historians, aristocrats or democrats, slavery has always been considered a necessary social and legal phenomenon. In this paper, which is the first part of two, a range of authors and texts that touch on the Greek idea of slavery are examined, considering philosophical ways of thinking about slaves. However, there are no anti-slavery intellectuals or philosophical currents, not even among those who are considered “nonconformists”. A thesis that confirming it with new remarks on the primary evidence is probably not a pointless exercise. A quick status questionis on the subject is useful to reiterate this basic thesis.

description: Introduction: Emotional labour is an integral aspect of teaching but remains largely absent from the extant literature on post primary teachers in Ireland. Furthermore, the role of teachers’ occupational identity in the formation of display rules, which serve as the foundation for emotional labour performance, is widely overlooked. The purpose of this study is to explore the reality of emotional labour performance for Irish post-primary school teachers with a particular consideration for identity and display rules.Method: A mixed-methods approach incorporating a combination of qualitative and quantitative methods was adopted for this study. Data was collected through semi-structured interviews with 14 participants and a questionnaire with 104 respondents.Results: Emotional labour is integral to the working lives of Irish post-primary school teachers. Display rules at the core of the emotional labour process were found to be dictated by both occupational identity and organisational requirements, independently of each other. The performance and consequences of emotional labour were found to vary depending on whether occupational display rules or organisational display rules are adhered to.Discussion. It is argued here that emotional labour when performed in adherence to organisational display rules will have more negative effects than when performed in adherence to occupational identity display rules. These findings further suggest that occupational display rules are influenced by life experiences and exhibit a gendered division, and organisational display rules are influenced by organisational culture and differ across organisations.

description: We compare APOGEE radial velocities (RVs) of young stars in the Orion A cloud with CO line gas emission and find a correlation between the two at large-scales, in agreement with previous studies. However, at smaller scales we find evidence for the presence of substructure in the stellar velocity field. Using a Friends-of-Friends approach we identify 37 stellar groups with almost identical RVs. These groups are not randomly distributed but form elongated chains or strings of stars with five or more members with low velocity dispersion, across lengths of 1-1.5~pc. The similarity between the kinematic properties of the APOGEE strings and the internal velocity field of the chains of dense cores and fibers recently identified in the dense ISM is striking and suggests that for most of the Orion A cloud, young stars keep memory of the parental gas substructure where they originated.

description: Tuberculosis/HIV co-infection is a bidirectional and synergistic combination of two very important pathogens in public health. To date, there have been limited clinical data regarding mortality rates among tuberculosis/HIV co-infected patients and the impact of antiretroviral therapy on clinical outcomes in Ethiopia. This study assessed the incidence and predictors of tuberculosis/HIV co-infection mortality in Southwest Ethiopia. Methods: A retrospective cohort study collated tuberculosis/HIV data from Jimma University Teaching Hospital for the period of September 2010 and August 2012. The data analysis used proportional hazards cox regression model at P value of ≤ 0.05 in the final model. Results: Fifty-five (20.2%) patients died during the study period and 272 study participants contributed 3 082.7 person month observations. Factors including: being aged between 35-44 years (AHR = 2.9; 95 % CI: 1.08-7.6), being a female sex worker (AHR = 9.1; 95 % CI: 2.7-30.7), being bed ridden as functional status (AHR = 3.2; 95 % CI: 1.2-8.7), and being at World Health Organization HIV disease stages 2 (AHR = 0.2; 95 % CI: 0.06-0.5), 3(AHR = 0.3; 95 % CI: 0.1-0.8) and 4(AHR = 0.2; 95 % CI: 0.04-0.55) were significant predictors of mortality for tuberculosis/HIV co-infected patients. Conclusions: Contrary to our expectations, the World Health Organization (WHO) HIV disease stage 1 was found to be a significant predictor of mortality. Higher mortality rates were observed in WHO disease stage 1 patients compared to patients in stages 2, 3 and 4. The current study also confirmed and reaffirmed known significant predictors of the mortality for tuberculosis/HIV co-infected patients including being 35-44 years, being a female sex worker and being bed ridden functional status. The occurrence of high death rate among tuberculosis/HIV co-infected cases needs actions to reduce this poor outcome.

description: Clustering has become an indispensable tool in the presence of increasingly large and complex data sets. Most clustering algorithms depend, either explicitly or implicitly, on the sampled density. However, estimated densities are fragile due to the curse of dimensionality and finite sampling effects, for instance in molecular dynamics simulations. To avoid the dependence on estimated densities, an energy-based clustering (EBC) algorithm based on the Metropolis acceptance criterion is developed in this work. In the proposed formulation, EBC can be considered a generalization of spectral clustering in the limit of large temperatures. Taking the potential energy of a sample explicitly into account alleviates requirements regarding the distribution of the data. In addition, it permits the subsampling of densely sampled regions, which can result in significant speed-ups and sublinear scaling. The algorithm is validated on a range of test systems including molecular dynamics trajectories of alanine dipeptide and the Trp-cage miniprotein. Our results show that including information about the potential-energy surface can largely decouple clustering from the sampling density.
Elementi per uno studio sul tasso di profitto dell'economia francese: 1896-2019

description: Considering that the rate of profit constitutes a key indicator for the analysis of the evolution of capitalist economies, this article aims to study the case of France from 1896 to 2019, i.e. 124 years in total. From a series of productive capital stocks reconstructed for the occasion, a profit rate is calculated at the macroeconomic level within a Marxian conceptual framework. In more than a century, three successive long waves can be identified, part of a secular trend towards the fall of the French profit rate. The latter, however, recovered several times during the three sub-periods, but eventually reoriented downwards, with fluctuations of ever smaller amplitude and an unfolding in a downward spiral of French capitalism. This long-term downward trend is mainly due to the increase in the organic composition of capital. Profit rate; Long Waves; Productive Capital; Organic Composition of Capital.

description: Motivated by the rapid development of heavy-flavor experiments, phenomenological studies of nonleptonic $\bar{B}_{d,s} \to D^{*}_{d,s} V$ and $\bar{B}_{d,s}^* \to D_{d,s} V$~($V=ρ\,,K^*$) decays are performed within the framework of QCD Factorization. Relative to previous works, the QCD corrections to the transverse amplitudes are evaluated at next-to-leading order. The theoretical predictions of the observables are updated. For the measured $\bar{B}_{d,s} \to D^{*}_{d,s} V$ decays, two tensions between theoretical results and experimental measurements, {\it i.e.} "$R_{ds}^{V}$ puzzle" and "$D^{*} V$~(or $R_{V/\ell\barν_\ell}$) puzzle", are presented after detailed analyses. For the $\bar{B}_{d,s}^* \to D_{d,s} V$ decays, they have relatively large branching fractions of the order $\gtrsim{\cal O}(10^{-9})$ and are in the scope of Belle-II and LHCb experiments. Moreover, they also provide a way to crosscheck the above-mentioned possible puzzles through the similar ratios $R_{ds}^{\prime V}$ and $R_{V/\ell\barν_\ell}^{\prime}$. More refined experimental measurements and theoretical efforts are required to confirm or refute such two anomalies.

description: [Objectives] To evaluate the status of soil nutrient and fertility in main dry farming regions of Laos, and to explore differences in soil nutrient content between regions and crop types. [Methods] By collecting 57 soil samples in the 0-20 cm layer of the main dryland in southern and northern provinces of Laos. Soil pH, organic matter, total nitrogen, available nitrogen, available phosphorus, available potassium, exchangeable calcium, exchangeable magnesium and available zinc content were analyzed. [Results] The soil in the main dry farming regions of Laos was acidic, the overall fertility level was good, and the exchangeable calcium and magnesium contents were low. There were differences in soil nutrient content in the dry farming regions of southern and northern Laos. Drylands where cassava and maize were planted had higher fertility. [Conclusions] It is suggested to apply lime or alkaline fertilizer in the dry land with acid soil to increase soil pH and increase the supply of soil calcium and magnesium. Organic fertilizer should be applied to improve soil water retention capacity, and it is necessary to pay attention to the fertilization ratio of macroelements to balance fertilization.

description: We study the synchronization of a van der Pol self-oscillator with Kerr anharmonicity to an external drive. We demonstrate that the anharmonic, discrete energy spectrum of the quantum oscillator leads to multiple resonances in both phase locking and frequency entrainment not present in the corresponding classical system. Strong driving close to these resonances leads to nonclassical steady-state Wigner distributions. Experimental realizations of these genuine quantum signatures can be implemented with current technology.
