description: The definition of complexity through Statistical Complexity Measures (SCM) has recently seen major improvements. Mostly, effort is concentrated in measures on time series. We propose a SCM definition for spatial dynamical systems. Our definition is in line with the trend to combine entropy with measures of structure (such as disequilibrium). We study the behaviour of our definition against the vectorial noise model of Collective Motion. From a global perspective, we show how our SCM is minimal at both the microscale and macroscale, while it reaches a maximum at the ranges that define the mesoscale in this model. From a local perspective, the SCM is minimum both in highly ordered and chaotic areas, while it reaches a maximum at the edges between such areas. These characteristics suggest this is a good candidate for detecting the mesoscale of arbitrary dynamical systems as well as regions where the complexity is maximal in such systems.

description: The axion solution to the strong CP problem calls for an explanation as to why the Lagrangian should be invariant under the global Peccei-Quinn symmetry, U(1)_PQ, to such a high degree of accuracy. In this paper, we point out that the U(1)_PQ can indeed survive as an accidental symmetry in the low-energy effective theory, if the standard model gauge group is supplemented by a gauged and discrete R symmetry, Z_N^R, forbidding all dangerous operators that explicitly break the Peccei-Quinn symmetry. In contrast to similar approaches, the requirement that the Z_N^R symmetry be anomaly-free forces us, in general, to extend the supersymmetric standard model by new matter multiplets. Surprisingly, we find a large landscape of viable scenarios that all individually fulfill the current experimental constraints on the QCD vacuum angle as well as on the axion decay constant. In particular, choosing the number of additional multiplets appropriately, the order N of the Z_N^R symmetry can take any integer value larger than 2. This has interesting consequences with respect to possible solutions of the mu problem, collider searches for vector-like quarks and axion dark matter.

description: African Refugees thought that by crossing the borders, they were escaping war, carrying their dreams and hopes for a better future. They did not know that they would face another war in the state of asylum. African refugees are marginalized in Cairo as a result of intersecting legal systems. The international law, national law, and the UNHCR policies are the main three legal systems that guide the refugee life. The gaps and contradictions between the three different legal systems along with the practice of these laws have dictated the current vulnerability status of the African refugees living in Egypt. In the case of African refugee women, the three legal systems are argued to create sexual vulnerable bodies as an enforced identity. An intersectional analysis of race, class, gender, and refugee status is carried out to understand these women's experience of sexual violence in Cairo. The international context of the African refugee women and the UNHCR policies despite the fact that international law and UNHCR has tailored a lot of policies and designed many programs that concentrate on the prevention and protection of refugee women against sexual violence, it does not make a real change or contribution in improving the vulnerable status that almost all the African refugee women in Egypt acquire but it is argued to be contributing in enforcing sexual vulnerability on African refugee women.

Grazing by wild and domesticated grazers occurs within many terrestrial ecosystems worldwide, with positive and negative impacts on biodiversity. Management of grazed lands in support of biological conservation could benefit from a compiled dataset of animal biodiversity within and adjacent to grazed sites. In this database, we have assembled data from the peer-reviewed literature that included all forms of grazing, co-occurring species, and site information. We reviewed 3,489 published articles and found 245 studies in 41 countries that surveyed animal biodiversity co-occurring with grazers. We extracted 16,105 observations of animal surveys for over 1,200 species in all terrestrial ecosystems and on all continents except Antarctica. We then compiled 28 different grazing variables that focus on management systems, assemblages of grazer species, ecosystem characteristics, and survey type. Our database provides the most comprehensive summary of animal biodiversity patterns that co-occur with wild and domesticated grazers. This database could be used in future conservation initiatives and grazing management to enhance the prolonged maintenance of ecosystems and ecosystem services.
title: Dynamic risk-based analysis of petroleum reservoir production systems
Creators: name: Mamudu, Abbas
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Petroleum reservoirs are complex process systems defined by intrinsically uncertain data and a distinct pressure gradient. The upstream sector’s assets are with huge uncertainties and high risks. Thus, the investments in these complex geologic process systems majorly suffer severe dynamic risks due to the process’ complex dynamics, process data’s temporal and spatial variabilities, and data/model’s uncertainties. Over time, the complex dynamic risks of the reservoir production system have resulted in unforeseen severe production fluctuations, total process system failures, and/or abrupt well shut-in due to uncontrollable circumstances. Hence, the need to introduce a multipurpose dynamic risk-based smart production prognostic approach to address the outlined inherent petroleum production challenges. This thesis presents dynamic risks assessment models for dynamic risks-based analysis of petroleum reservoir production systems. Different possible production scenarios are captured with the developed adaptive hybrid model with the following highlighted novel scientific contributions. Firstly, a dynamic risk-based predictive model is introduced to forecast production and capture the parameters variabilities, data and model’s uncertainties, and dynamic risks of primary recovery processes. This is followed with an introduced novel model for dynamic risks monitoring and production forecast of secondary recovery processes. A novel model is also presented to incorporate dual reservoir energy support mechanisms in production predictions and associated dynamic risks forecast under lift mechanisms. In addition, a dynamic economic risks analysis model is proposed to consider economic risk assessment of the reservoir production systems. Lastly, a dynamic risks-based smart model is proposed to capture sand face pressure enhancement influence on the reservoir production system with production pump schemes.
Calculation of the spiked harmonic oscillators through a generalized pseudospectral method

Year: 2013
Subjects: subject: Quantum Physics (quant-ph)

description: The generalized pseudospectral method is employed for the accurate calculation of eigenvalues, densities and expectation values for the spiked harmonic oscillators. This allows \emph{nonuniform} and \emph{optimal} spatial discretization of the corresponding single-particle radial Schrödinger equation satisfying the Dirichlet boundary conditions leading to the standard diagonalization of the symmetric matrices. The present results for a large range of potential parameters are in excellent agreement with those from the other accurate methods available in the literature. The ground and excited states (both low as well as high angular momentum states) are obtained with equal ease and accuracy. Some new states including the higher excited states are reported here for the first time. This offers a simple, accurate and efficient method for the treatment of these and a wide variety of other singular potentials of physical and chemical interest in quantum mechanics.

description: We present theoretical expectations for non-thermal emission due to the bulk Comptonization at the ultra-relativistic shock breakout. We calculate the transfer of photons emitted from the shocked matter with a Monte Carlo code fully taking into account special relativity. As a hydrodynamical model, we use a self-similar solution of Nakayama & Shigeyama (2005). Our calculations reveal that the spectral shape exhibits a double peak or a single peak depending on the shock temperature at the shock breakout. If it is significantly smaller than the rest energy of an electron, the spectrum has a double peak. We also display a few example of light curves, and estimate the total radiation energy. In comparison with observations of gamma-ray bursts, a part of the higher energy component in the spectra and the total energy can be reproduced by some parameter sets. Meanwhile, the lower energy counterpart in the Band function is not reproduced by our results and the duration time seems too short to represent the entire event of a gamma-ray burst. Therefore the subsequent phase will constitute the lower energy part in the spectrum.

description: We systematically analyzed the spectra of X-ray binary pulsars observed with GINGA (Mihara 1995). A new model NPEX (Negative and Positive power-laws EXponential) was introduced t o represent the pulsar continuum. Combining the NPEX continuum with the CYAB factor (cyclotron resonance scattering model), we successfully fit the whole-band spectra of all the pulsars. A possible physical meaning of the NPEX model is the Comptonized spectra. By using the smooth and concave NPEX model, the cyclotron structures were detected from 12 pulsars, about a half of the 23 sources, including new discoveries from LMC X-4 and GS 1843+00. The magnetic fields were scattered in the range of $3\times10^{11}$ - $5\times10^{12}$ G. The distribution was shown for the first time, which is remarkably similar to that of radio pulsars with a peak at $2 \times 10^{12}$ G. The double harmonic cyclotron structures of 4U 0115+63 in 1990 changed to a sin gle structure in 1991. The resonance energy also increased by 40 % as the luminosity decreased to 1/6. If we attribute this change to the height of the scattering region in a dipole m agnetic field, the height change is $\sim$ 1.1 km. Such changes of the resonance energies with luminosities are observed from 5 pulsars and can be explained by the accretion column height model.

description: Dielectric spectra (10^4-10^11 Hz) of water and ice at 0 °C are considered in terms of proton conductivity and compared to each other. In this picture, the Debye relaxations, centered at 1/τ_W ~ 20 GHz (in water) and 1/τ_I ~ 5 kHz (in ice), are seen as manifestations of diffusion of separated charges in the form of H3O+ and OH- ions. The charge separation results from the self-dissociation of H2O molecules, and is accompanied by recombination in order to maintain the equilibrium concentration, N. The charge recombination is a diffusion-controlled process with characteristic lifetimes of τ_W and τ_I, for water and ice respectively. The static permittivity, ε(0), is solely determined by N. Both, N and ε(0), are roughly constant at the water-ice phase transition, and both increase, due to a slowing down of the diffusion rate, as the temperature is lowered. The transformation of the broadband dielectric spectra at 0 °C with the drastic change from τ_W to τ_I is mainly due to an abrupt (by 0.4 eV) change of the activation energy of the charge diffusion.

description: With the increasing prevalence of myopia, evaluating its relationship with objective light exposure as a potential adjustable environmental factor in myopia development has been an emerging research field in recent years. From a thorough literature search, we identify ten wearable light meters from human studies on light exposure and myopia and present an overview of their parameters, thereby demonstrating the wide between-device variability and discussing its implications. We further identify 20 publications, including two reanalyses, reporting investigations of light-myopia associations with data from human subjects wearing light meters. We thoroughly review the publications with respect to general characteristics, aspects of data collection, participant population, as well as data analysis and interpretation, and also assess potential patterns regarding the absence or presence of light-myopia associations in their results. In doing so, we highlight areas in which more research is needed as well as several aspects that warrant consideration in the study of light exposure and myopia.

description: The properties of many intrinsic defects in the wide band gap semiconductor LaAlO3 are studied using the screened hybrid functional of Heyd, Scuseria, and Ernzerhof (HSE). As in pristine structures, exact exchange included in the screened hybrid functional alleviates the band gap underestimation problem, which is common to semilocal functionals; this allows accurate prediction of defect properties. We propose correction-free defect energy levels for bulk LaAlO3 computed using HSE that might serve as guide in the interpretation of photoluminescence experiments.

description: "Airports Intelligent Inspection and Guidance System with Access Control and Health Monitoring Using IoT and Artificial Intelligence for Oman Airports" is an IoT project with AI touch that aims to provide an easier and smart way to manage traditional travel operations. The traditional way of checking in is that travelers must queue at immigration offices for an extended period which on many occasions results in delays or missed flights. This project uses Internet of Things technology combined with computer vision to provide an easier and smarter way to interact with each other. The main technology that will be implemented in this project is the use
 of OpenCV for face detection and recognition using the KNN algorithm. Starting with selfregistration desks, a Raspberry Pi camera will capture the photo, associate it with relevant information, and record that information into a central database. Guidance and access control systems will detect a person using a motion sensor which in turn operates the system to identify the person and provides the required information through an LCD screen. The health and safety monitoring system using the Pi camera will identify people who are not wearing face masks and thus trigger an alert to those concerned. Along the way, it will also turn on/off the stepper motor system to open/close doors or gates, or display information messages.”

description: The energy released by an active galactic nucleus (AGN) has a strong impact on the surrounding interstellar medium (ISM). This feedback is considered to be the regulating factor for the growth of the central massive black hole, and for the rate of star formation in a galaxy. We have located, using Very Long Baseline Interferometry (VLBI), the fast outflow of neutral hydrogen in the young, restarted radio loud AGN 4C12.50. The outflow is located 100 pc from the nucleus where the radio jet interacts with the ISM, as well as around the associated radio lobe. These observations show that the radio plasma drives the outflow and removes gas from the central regions, and that jet driven outflows can play a relevant role in feedback mechanisms.

description: This scoping review was conducted to synthesize existing literature into a map of the common needs of families caring for patients with traumatic brain injury (TBI) at home. A systematic search of studies published between January 2012 and December 2022 was conducted across databases. The selected studies reported the needs or unmet needs of patients with TBI and/or their family caregivers (FCs). A total of 12 publications were identified. The results suggest that the common needs of families caring for patients with TBI at home include: information about TBI as a disease; information about the continuum of TBI healthcare services; information about adaptive technologies; education and skilling of FCs; psychological support and counseling; physical and occupational therapy services; follow-up care and transitional care management; respite care; peer support; financial assistance, advocacy, and legal services; emotional support from the family and community; and assistance with physical patient care and instrumental activities of daily living. The mapped needs provide insight into supportive interventions required to enhance the health outcomes of patients with TBI and their families during and after rehabilitation. The needs also highlight directions for research and healthcare services for patients with TBI. The families caring for patients with traumatic brain injury at home end up living in situations characterized by multiple unmet needs, and these can be a source of poor health outcomes for the family and patients with traumatic brain injury.The identified needs of families caring for patients with traumatic brain injury reveal gaps in the discharge planning and care coordination after acute and rehabilitation care.Addressing these needs requires a multidisciplinary approach and planning.Interventions using a holistic approach to address the identified needs may significantly improve the health outcomes of patients with traumatic brain injury and their families.

description: Feeder cattle prices are driven by supply and demand for live cattle (i.e., finished cattle) that are in turn driven by supply and demand for beef. Supply and demand in the cattle and beef industries change seasonally, resulting in seasonal price changes for feeder cattle, finished cattle and beef. For example, on the cattle side, many cow-calf producers calve in late winter and early spring months (February and March) and market cattle in the fall (October and November). The increased supply of lower-weighted calves (i.e., less than 600 pounds) induces lower prices in the fall, whereas in the spring (March or April), there is a lower supply of animals under 600 pounds that typically sell at higher prices. Additionally, the timing of calving greatly influences when an animal will enter the feedlot and thereby when it will be harvested. From a beef demand perspective, the greatest demand for beef generally occurs during the summer grilling months, and the softest demand occurs during the winter months. Thus, these factors also seasonally influence feeder cattle prices. Outside of supply and demand for beef, feeder cattle prices are regularly influenced by changes in feed prices, as feed costs are a large component of feedlot production costs. However, there are occasions when other external (exogenous) shocks influence feeder cattle prices, such as bovine spongiform encephalopathy (BSE) in 2003, drought in 2011 and 2012, and the Tyson beef packing facility fire in 2019. Each of these external shocks affected the typical supply and demand of finished cattle, which also transmitted to feeder cattle prices. Though these shocks were exogenous to the market, they were primarily isolated to the cattle industry or agricultural production industries; that is, they did not involve the broader United States population. Coronavirus (COVID-19) is another external shock influencing cattle prices in early 2020. The difference between COVID-19 and the external shocks discussed above is that coronavirus influenced most national and international markets, not just beef cattle. The purpose of this publication is to illustrate how Tennessee feeder cattle prices were impacted by COVID-19 in the first four months of 2020, compared to those same four months historically (based on data for cattle sold through Tennessee auction markets reported by USDA-AMS).

description: The INTEGRAL and Swift hard X-ray surveys have identified a large number of new sources, among which many are proposed as Cataclysmic Variables (CVs). Here we present the first detailed study of three X-ray selected CVs, Swift J1907.3-2050, IGRJ12123-5802, and IGRJ19552+0044 based on XMM-Newton, Suzaku, Swift observations and ground based optical and archival nIR/IR data. Swift J1907.3-2050 is highly variable from hours to months-years at all wavelengths. No coherent X-ray pulses are detected but rather transient features. The X-ray spectrum reveals a multi-temperature optically thin plasma absorbed by complex neutral material and a soft black body component arising from a small area. These characteristics are remarkably similar to those observed in magnetic CVs. A supra-solar abundance of nitrogen could arise from nuclear processed material from the donor star. Swift J1907.3-2050 could be a peculiar magnetic CV with the second longest (20.82 h) binary period. IGRJ12123-5802 is variable in the X-rays on a timescale of ~7.6 h. No coherent pulsations are detected, but its spectral characteristics suggest that it could be a magnetic CV of the Intermediate Polar (IP) type. IGRJ19552+0044 shows two X-ray periods, 1.38 h and 1.69 h and a X-ray spectrum characterized by a multi-temperature plasma with little absorption.We derive a low accretion rate, consistent with a CV below the orbital period gap. Its peculiar nIR/IR spectrum suggests a contribution from cyclotron emission. It could either be a pre-polar or an IP with the lowest degree of asynchronism.

Toward an Understanding of Vertical Momentum Transports in Cloud-System-Resolving Model Simulations of Multiscale Tropical Convection

description: This study examines the characteristics of convective momentum transport (CMT) and gravity wave momentum transport (GWMT) in two-dimensional cloud-system-resolving model simulations, including the relationships between the two transports. A linear group velocity criterion is shown to objectively separate CMT and GWMT. The GWMT contribution is mostly consistent with upward-propagating gravity waves and is present in the troposphere and the stratosphere. The CMT contribution forms a large part of the residual (nonupward-propagating contribution) and dominates the fluxes in the troposphere. Additional analysis of the vertical sensible heat flux supports the physical interpretation of the two contributions, further isolating the effects of unstable convection from vertically propagating gravity waves. The role of transient and nonconservative (friction and diabatic heating) processes in generating momentum flux and their dependence on changes in convective organization was assessed using a pseudomomentum budget analysis. Nonconservative effects were found to dominate the transports; the GWMT contribution involved a diabatic source region in the troposphere and a dissipative sink region in the stratosphere. The CMT contribution was consistent with transport between the boundary layer and free troposphere via tilted convection. Transient buoyancy–vorticity correlations highlighted wave sources in the region of convective outflow and the boundary layer. These sources were akin to the previously described “mechanical oscillator” mechanism. Fluxes associated with this upper-level source were most sensitive to convective organization, highlighting the mechanism by which changes in organization are communicated to GWMT. The results elucidate important interactions between CMT and GWMT, adding further weight to suggestions that the two transports should be linked in parameterizations.

In the $K$-contact case we give sufficient conditions for smoothness of the moduli space away from reducible connections and show the dimension is given by the index of an operator elliptic transverse to the Reeb foliation. The moduli spaces are shown to be Kähler when the $5$-manifold $M$ is Sasakian and hyperKähler when $M$ is transverse Calabi-Yau. We show how the transverse index can be computed in various cases, in particular we compute the index for the toric Sasaki-Einstein spaces $Y^{p,q}$.

Auch wenn die Pandemie schon einige Prognosen durchkreuzt hat. So oder so wird die Rückkehr wohl in eingeschränkter Form erfolgen. Nichtsdestotrotz wird vermutlich dem lange vorenthaltenen Austausch mit Kollegen ein besonders großer Stellenwert beigemessen werden. Innovationsförderung durch Kommunikationsförderung - das war bereits vor der Pandemie eine Kernfunktion moderner und offener Bürostrukturen und wird nach der Pandemie vermutlich der wichtigste Treiber, das Büro aufzusuchen. Das sagen zumindest Trendforscher.

Aber Vorsicht, zu viel des Guten ist schädlich, das gilt auch für soziale Interaktion. Die gesundheitlichen Folgen sozialer Überstimulation und mangelnder Rückzugsmöglichkeiten sollten nicht unterschätzt werden. Firmen können stattdessen einiges dafür tun, dass der Arbeitsplatz diesbezüglich gesundheitserhaltender wird.

Diarrhea--Epidemiology

description: The 2009 A/H1N1 influenza pandemic has received a great deal of attention from public health authorities. Our study examines whether this pandemic and the resulting public health measures could have impacted acute diarrhea, a prevalent, highly transmissible and historically monitored disease. Using augmentation procedures of national data for the previous five years (2004–2009), we estimated the expected timing and incidence of acute diarrhea in France in 2009–2010 and evaluated differences with the observed. We also reviewed national hand gels for the same period. Number of episodes of acute diarrhea in France in 2009–2010 was significantly lower than expected until the third week of December (−24%, 95% CI [−36%; −9%]), then significantly higher (+40%, 95% CI [22%; 62%]), leading to a surplus of 574,440 episodes. The epidemic was delayed by 5 weeks with a peak 1.3 times higher than expected. Hand-gels sales inversely correlated with incidence of both influenza-like illness and acute diarrheal disease. Among individuals >65 yo, no excess cases of influenza and no excess rebound in acute diarrhea were observed, despite similar delay in the onset of the seasonal diarrheal epidemic. Our results suggest that at least one endemic disease had an unexpected behavior in 2009–2010. Acute diarrhea seems to have been controlled during the beginning of the pandemic in all age groups, but later peaked higher than expected in the younger population. The all-age delay in seasonal onset seems partly attributable to hand-gels use, while the differential magnitude of the seasonal epidemic between young and old, concurrent for both influenza and acute diarrhea, is compatible with disease interaction.

description: The presence of g- and p-modes allows testing stellar models from the core to the envelope. Moreover, binarity in an eclipsing system constrains the physical parameters of the pulsating star. CoRot ID 100866999 is a relatively large-amplitude hybrid gDor - dSct star with two clearly distinct frequency domains. The large number of detected frequencies allows a detailed study of the interaction between them. In addition, we can derive the fundamental parameters of both components from the study of the eclipsing light curve. After removing the eclipsing phases, we analyzed the data with the Period04 package up to S/N=4. The light curve was then prewhitened with these oscillation frequencies to derive the fundamental parameters of the two components. The eclipsing light curve analysis results in a (1.8+1.1)\,Mo system, both components being main sequence stars. We detect 124 frequencies related to luminosity variations of the primary. They are present in two well-separated domains: 89 frequencies in the interval [0.30;3.64]/d and 35 in the interval [14.57; 33.96]/d. There are 22 gDor frequencies separated by a constant period interval Delta P = 0.03493 d. These frequencies correspond to a series of g-modes of degree ell=1 with successive radial orders k. We identify 21 linear combinations between the first nine gDor frequencies. The dSct domain is dominated by a large-amplitude frequency F=16.9803 /d. The eight first gDor frequencies f_i are present with much lower amplitude in the delta Scuti domain as F +/- f_i. These interactions between g- and p-modes confirm the phenomenon we detected in another CoRoT star. The amplitude and the phase of the main frequency F shows a double-wave modulation along the orbital phase, giving rise to series of combination frequencies. Such combination frequencies are also detected, with lower amplitude, for the first gDor modes.

description: Miles Davis traced his rising fame in the 1950s to changes taking place in society. "There was a new mood coming into the country," he stated in his autobiography. "Black and white people were starting to get together, and in the music world Uncle Tom images were on their way out." Describing himself as a "nonconformist"-"cool and hip and angry and sophisticated and ultra clean"-Davis identified with others in that period who were breaking barriers and challenging authority: Martin Luther King leading the Montgomery bus boycott, Marian Anderson appearing as the first black singer at the Metropolitan Opera, Marlon Brando and James Dean gaining popularity as actors by portraying rebels (Davis 1989:197-98). Davis's bold, brash persona earned him a special degree of respect from black Americans. Writer Amiri Baraka considered the trumpeter his "ultimate culture hero," someone who embodied "a black attitude that had grown steadily more ubiquitous in the 1950s-defiance" (Baraka 1996:41, 48). Given Davis's affiliation, first with a group of postwar jazz musicians carving out a new identity for black artists, then with a larger movement engaged in transforming the nation's cultural and political landscape (including the Beats, Civil Rights activists, Abstract Expressionists, and others), it is remarkable that in 1958 he teamed up with arranger Gil Evans to record an album devoted to Porgy and Bess. Ever since its premiere, the opera by the Gershwins and Heyward had sparked controversy and caused Mrican Americans to speak out in protest.
On Money and Motivation: A Quasi-Experimental Analysis of Financial Incentives for College Achievement

description: Programs linking college aid to academic achievement could work either by lowering the cost of college or by inducing additional student effort. This article examines the PROMISE program in West Virginia, which offers free tuition to students who maintain a minimum GPA and course load. Using administrative data, Scott-Clayton exploits discontinuities in the eligibility formula and the timing of implementation to estimate causal effects, finding robust and significant impacts on key academic outcomes. Impacts are concentrated around the annual requirements for scholarship renewal, suggesting that the program works via incentives for academic achievement, not simply by relaxing financial constraints.

description: We have investigated the influence of 3d-4f spin interaction on magnetic and magnetocaloric properties of DyCrO$_4$ and HoCrO$_4$ compounds by magnetization and heat capacity measurements. Both the compounds exhibit complicated magnetic properties and huge magnetic entropy change around the ferromagnetic transition due to the strong competition between ferromagnetic and antiferromagnetic superexchange interactions. For a field change of 8 T, the maximum values of magnetic entropy change ($ΔS_{M}^{max}$), adiabatic temperature change ($ΔT_{ad}$), and refrigerant capacity (RC) reach 29 J kg$^{-1}$ K$^{-1}$, 8 K, and 583 J kg$^{-1}$, respectively for DyCrO$_4$ whereas the corresponding values for HoCrO$_4$ are 31 J kg$^{-1}$ K$^{-1}$, 12 K, and 622 J kg$^{-1}$. $ΔS_{M}^{max}$, $ΔT_{ad}$, and RC are also quite large for a moderate field change. The large values of magnetocaloric parameters suggest that the zircon-type DyCrO$_4$ and HoCrO$_4$ could be the potential magnetic refrigerant materials for liquefaction of hydrogen.

description: Cardiac tissue engineering has a potential to provide functional, synchronously contractile tissue constructs for heart repair, and for studies of development and disease using in vivo-like yet controllable in vitro settings. In both cases, the utilization of bioreactors capable of providing biomimetic culture environments is instrumental for supporting cell differentiation and functional assembly. In the present study, neonatal rat heart cells were cultured on highly porous collagen scaffolds in bioreactors with electrical field stimulation. A hallmark of excitable tissues such as myocardium is the ability to propagate electrical impulses. We utilized the method of optical mapping to measure the electrical impulse propagation. The average conduction velocity recorded for the stimulated constructs (14.4 plus or minus 4.1 cm/s) was significantly higher than that of the nonstimulated constructs (8.6 plus or minus 2.3 cm/s, p = 0.003). The measured electrical propagation properties correlated to the contractile behavior and the compositions of tissue constructs. Electrical stimulation during culture significantly improved amplitude of contractions, tissue morphology, and connexin-43 expression compared to the nonsimulated controls. These data provide evidence that electrical stimulation during bioreactor cultivation can improve electrical signal propagation in engineered cardiac constructs.

description: Dust grains are sputtered away in the hot gas behind shock fronts in supernova remnants, gradually enriching the gas phase with refractory elements. We have measured emission in C IV $λ$1550 from C atoms sputtered from dust in the gas behind a non-radiative shock wave in the northern Cygnus Loop. Overall, the intensity observed behind the shock agrees approximately with predictions from model calculations that match the Spitzer 24 micron and the X-ray intensity profiles. Thus these observations confirm the overall picture of dust destruction in SNR shocks and the sputtering rates used in models. However, there is a discrepancy in that the CIV intensity 10" behind the shock is too high compared to the intensities at the shock and 25" behind it. Variations in the density, hydrogen neutral fraction and the dust properties over parsec scales in the pre-shock medium limit our ability to test dust destruction models in detail.

Reuse of Human Excreta in Developing Countries: Agricultural Fertilization Optimization

description: In developing nations, 1.2 billion people suffer from a lack of a basic sanitation system and fecal sludge manage- ment challenges, despite many efforts to combat this issue. Fecal sludge is a mixture of waste, including human excreta, soil, and water. Human excreta contains a significant amount of nutrients that can be used in agricultural fertilizers. The use of human excreta in agricultural fertilizers would reduce the need for artificial fertilizers and improve human excreta disposal through the use of composting and vermicomposting toilet systems. In developing nations where soil conditions are poor and fresh water is unavailable, the use of human excreta in fertilizer can ameliorate two problems: low food productivity and lack of sanitation service. Among the seventeen Sustainable Development Goals (SDGs) established by the United Nations (UN), ensuring a sani- tation system for everyone addresses the Goal 6, securing food for everyone. Additionally, enhancing low food productivity addresses the second goal of the SDGs, improving low food productivity. Thus, more efficient use of human excreta can help achieve two SDGs at the same time.
