Probing R-parity violating models of neutrino mass at the Tevatron via top Squark decays

description: We have estimated the limiting branching ratio of the R-parity violating (RPV) decay of the lighter top squark, $\tilde t_1 \ar l^+ d$ ($l=e$ or $μ$ and d is a down type quark of any flavor), as a function of top squark mass($\MST$) for an observable signal in the di-lepton plus di-jet channel at the Tevatron RUN-II experiment with 2 fb$^{-1}$ luminosity. Our simulations indicate that the lepton number violating nature of the underlying decay dynamics can be confirmed via the reconstruction of $\MST$. The above decay is interesting in the context of RPV models of neutrino mass where the RPV couplings ($λ'_{i3j}$) driving the above decay are constrained to be small ($\lsim 10^{-3} - 10^{-4} $). If $\tilde t_1$ is the next lightest super particle - a theoretically well motivated scenario - then the RPV decay can naturally compete with the R-parity conserving (RPC) modes which also have suppressed widths. The model independent limiting BR can delineate the parameter space in specific supersymmetric models, where the dominating RPV decay is observable and predict the minimum magnitude of the RPV coupling that will be sensitive to Run-II data. We have found it to be in the same ballpark value required by models of neutrino mass, for a wide range of $\MST$. A comprehensive future strategy for linking top squark decays with models of neutrino mass is sketched.

Large-$N$ Random Matrix Gravity and the Double Hierarchy Problem

description: Why are the cosmological constant, electroweak and Planck scales so different? This ``double hierarchy" problem, where $Λ\ll M^2_{EW} \ll M^2_p$, is one of the most pressing in fundamental physics. We show that in a theory of $N$ randomly coupled massive gravitons at the electroweak scale, these scales are linked precisely by such a double hierarchy for large $N$, with intriguing cosmological consequences. Surprisingly, in all the physical scales, only one massless graviton emerges which is also, effectively, the only one that is coupled to matter, giving rise to standard Einstein gravity, with $M_p^2\, G_{μν}= T_{μν}$ at large $N$. In addition there is a tower of massive gravitons, the lightest of which can drive late-time acceleration. In this scenario, the observed empirical relation $Λ\, M_p^2 \sim M_{EW}^4$ as well as the double hierarchy, arise naturally since $Λ\sim M^2_{EW}/\sqrt{N}$ and $M^2_p \sim \sqrt{N}M_{EW}^2$.

description: We present two developments which enhance the predictive power of empirical shell-model Hamiltonians for cases in which calibration data are sparse. A recent improvement in the ab initio derivation of effective Hamiltonians leads to a much better starting point for the optimization procedure. In addition, we introduce a protocol to avoid overfitting, enabling a more reliable extrapolation beyond available data. These developments will enable more robust predictions for exotic isotopes produced at rare isotope beam facilities and in astrophysical environments.

description: 30-component, of the first order, equation for a spin 2 particle, equivalent to the second order Pauli-Fierz one, is generalized to presence of an external electromagnetic field as well as a curved background space-time geometry. The essential property of the generally covariant wave equation obtained is that here from the very beginning, in accordance with requirement of the Pauli-Fierz approach, a set of additional relations on 30-component wave function for eliminating complementary spin 0 and spin 1 fields is present at the starting equation.

description: (Abridged). We introduce the Aarhus Red Giants Challenge, a series of detailed comparisons between widely used stellar evolution and oscillation codes aiming at establishing the minimum level of uncertainties in properties of red giants arising solely from numerical implementations. Using 9 state-of-the-art stellar evolution codes, we defined a set of input physics and physical constants for our calculations and calibrated the convective efficiency to a specific point on the main sequence. We produced evolutionary tracks and stellar structure models at fixed radius along the red-giant branch for masses of 1.0 M$_\odot$, 1.5 M$_\odot$, 2.0 M$_\odot$, and 2.5 M$_\odot$, and compared the predicted stellar properties. Once models have been calibrated on the main sequence we find a residual spread in the predicted effective temperatures across all codes of ~20 K at solar radius and ~30-40 K in the RGB regardless of the considered stellar mass. The predicted ages show variations of 2-5% (increasing with stellar mass) which we track down to differences in the numerical implementation of energy generation. The luminosity of the RGB-bump shows a spread of about 10% for the considered codes, which translates into magnitude differences of ~0.1 mag in the optical V-band. We also compare the predicted [C/N] abundance ratio and found a spread of 0.1 dex or more for all considered masses. Our comparisons show that differences at the level of a few percent still remain in evolutionary calculations of red giants branch stars despite the use of the same input physics. These are mostly due to differences in the energy generation routines and interpolation across opacities, and call for further investigations on these matters in the context of using properties of red giants as benchmarks for astrophysical studies.

Neutrino transport in accretion disks

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We test approximate approaches to solving a neutrino transport problem that presents itself in the analysis of some accretion-disk models. Approximation #1 consists of replacing the full, angular- dependent, distribution function by a two-stream simulation, where the streams are respectively outwardly and inwardly directed, with angles $\cos θ=\pm 1/\sqrt{3}$ to the vertical. In this approximation the full energy dependence of the distribution function is retained, as are the energy and temperature dependences of the scattering rates. Approximation #2, used in recent works on the subject, replaces the distribution function by an intensity function and the scattering rates by temperature-energy-averaged quantities. We compare the approximations to the results of solving the full Boltzmann equation. Under some interesting conditions, approximation #1 passes the test; approximation #2 does not. We utilize the results of our analysis to construct a toy model of a disc at a temperature and density such that relativistic particles are more abundant than nucleons, and dominate both the opacity and pressure. The nucleons will still provide most of the energy density. In the toy model we take the rate of heat generation (which drives the radiative transfer problem) to be proportional to the nucleon density. The model allows the simultaneous solution of the neutrino transport and hydrostatic equilibrium problems in a disk in which the nucleon density decreases approximately linearly as one moves from the median plane of the disk upwards, reaching zero on the upper boundary.

Generalized effective mass approach for cubic semiconductor n-MOSFETs on arbitrarily oriented wafers

description: The general theory for quantum simulation of cubic semiconductor n-MOSFETs is presented within the effective mass equation approach. The full three-dimensional transport problem is described in terms of coupled transverse subband modes which arise due to quantum confinement along the body thickness direction. Couplings among the subbands are generated for two reasons: due to spatial variations of the confinement potential along the transport direction, and due to non-alignment of the device coordinate system with the principal axes of the constant energy conduction band ellipsoids. The problem simplifies considerably if the electrostatic potential is separable along transport and confinement directions, and further if the potential variations along the transport direction are slow enough to prevent dipolar coupling (Zener tunneling) between subbands. In this limit, the transport problem can be solved by employing two unitary operators to transform an arbitrarily oriented constant energy ellipsoid into a regular ellipsoid with principal axes along the transport, width and confinement directions of the device. The effective masses for several technologically important wafer orientations for silicon and germanium are calculated in this paper.

Publisher: name: MDPI

description: Seeds are an important life cycle stage because they guarantee plant survival in unfavorable environmental conditions and the transfer of genetic information from parents to offspring. However, similar to every organ, seeds undergo aging processes that limit their viability and ultimately cause the loss of their basic property, i.e., the ability to germinate. Seed aging is a vital economic and scientific issue that is related to seed resistance to an array of factors, both internal (genetic, structural, and physiological) and external (mainly storage conditions: temperature and humidity). Reactive oxygen species (ROS) are believed to initiate seed aging via the degradation of cell membrane phospholipids and the structural and functional deterioration of proteins and genetic material. Researchers investigating seed aging claim that the effective protection of genetic resources requires an understanding of the reasons for senescence of seeds with variable sensitivity to drying and long-term storage. Genomic integrity considerably affects seed viability and vigor. The deterioration of nucleic acids inhibits transcription and translation and exacerbates reductions in the activity of antioxidant system enzymes. All of these factors significantly limit seed viability.

description: Die Bioökonomie wird als wichtiger Beitrag für eine Zukunft diskutiert, in der es gelingt, ökonomische Belange mit den planetaren Grenzen zu vereinen. Durch den zunehmenden Einsatz biobasierter Ressourcen zur Energiegewinnung und in der industriellen Produktion sollen dem Klimawandel und der Verknappung fossiler Ressourcen begegnet werden. Dabei erfordert der Wandel zu einer biobasierten Wirtschaft grundlegende Transformationsprozesse, die von allen Akteuren der Gesellschaft mitgetragen werden müssen. Vorliegender Beitrag untersucht auf Basis einer repräsentativen Befragung die Einstellungen der Bevölkerung zur Bioökonomie und ermittelt mit Hilfe von Faktor- und Clusteranalysen Gruppen mit in sich homogenen Einstellungsmustern. Während 62% die wirtschaftliche Entwicklung in Richtung einer Bioökonomie unterstützen, sich allerdings in der Art der verwendeten Mittel uneins sind, sehen 38% keine Notwendigkeit in der zunehmenden Nutzung biobasierter Ressourcen. Es wird gefolgert, dass erhebliche Anstrengungen in der neutralen Wissenschaftskommunikation vonnöten sind, um den großen Anteil an „Unbeteiligten“ zu reduzieren. Darüber hinaus müssen politische Weichenstellungen, die die künftige Bioökonomie maßgeblich formen, offen kommuniziert und klar begründet werden.

Carrying out a scattering calculation we single out the purely geometrical effect. We apply our method to the experimentally relevant case of Gaussian shaped atomic samples stored in single beam optical dipole traps and probed by a Gaussian beam. We derive analytical scaling relations for the effect of the interaction geometry and compare our findings to results from 1-dimensional models of light propagation.

description: Purpose: To determine whether unilateral leg whole-body vibration (WBV) strength training induces strength gain in the untrained contralateral leg muscle. The secondary aim was to determine the potential role of spinal neurological mechanisms regarding the effect of WBV exercise on contralateral strength training. Materials and Methods: Forty-two young adult healthy volunteers were randomized into two groups: WBV exercise and Sham control. An isometric semi-squat exercise during WBV was applied regularly through 20 sessions. WBV training was applied to the right leg in the WBV group and the left leg was isolated from vibration. Sham WBV was applied to the right leg of participants in the Control group. Pre- and post-training isokinetic torque and reflex latency of both quadricepses were evaluated. Results: The increase in the strength of right (vibrated) knee extensors was 9.4 ± 10.7% in the WBV group (p = .001) and was 1.2 ± 6.6% in the Control group (p = .724). The left (non-vibrated) extensorsvibrated) knee extensors w4 ± 8.4% in the WBV group (p = .038), whereas it decreased by 1.4 ± 7.0% in the Control (p = .294). The strength gains were significant between the two groups. WBV induced the reflex response of the quadriceps muscle in the vibrated ipsilateral leg and also in the non-vibrated contralateral leg, though with a definite delay. The WBV-induced muscle reflex (WBV-IMR) latency was 22.5 ± 7.7 ms for the vibrated leg and 39.3 ± 14.6 ms for the non-vibrated leg. Conclusions: Chronic WBV training has an effect of the cross-transfer of strength to contralateral homologous muscles. The WBV-induced muscular reflex may have a role in the mechanism of cross-transfer strength.
The density gradient inside molecular-gas clumps as a booster of their star formation activity

Year: 2019
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Star-forming regions presenting a density gradient experience a higher star formation rate than if they were of uniform density. We refer to the ratio between the star formation rate of a spherical centrally-concentrated gas clump and the star formation rate that this clump would experience if it were of uniform density as the magnification factor $ζ$. We map $ζ$ as a function of clump mass, radius, initial volume density profile and star formation time-span. For clumps with a steep density profile (i.e. power-law slope ranging from $-3$ to $-4$, as observed in some high-density regions of Galactic molecular clouds), we find the star formation rate to be at least an order of magnitude higher than its top-hat equivalent. This implies that such clumps experience faster and more efficient star formation than expected based on their mean free-fall time. This also implies that measurements of the star formation efficiency per free-fall time of clumps based on their global properties, namely, mass, mean volume density and star formation rate, present wide fluctuations. These reflect the diversity in the density profile of star-forming clumps, not necessarily variations in the physics of star formation. Steep density profiles inside star-cluster progenitors may be instrumental in the formation of multiple stellar populations, such as those routinely observed in old globular clusters.

description: $H$-$T$ diagram of 3D diluted Ising antiferromagnet Ni$_{c}$Mg$_{1-c}$(OH)$_{2}$ with $c$ = 0.8 has been determined from measurements of SQUID DC magnetization and AC magnetic susceptibility. At $H$ = 0, this compound undergoes two magnetic phase transitions: an antiferromagnetic (AF) transition at the Néel temperature $T_{N}$ (= 20.7 K) and a reentrant spin glass (RSG) transition at $T_{RSG}$ ($\approx$ 6 K). The $H$-$T$ diagram consists of the RSG, spin glass (SG), and AF phases. These phases meet a multicritical point $P_{m}$ ($H_{m}$ = 42 kOe, $T_{m}$ = 5.6 K). The irreversibility of susceptibility defined by $δ$ (= $χ_{FC} - χ_{ZFC}$) shows a negative local minimum for 10 $\leq H \leq$ 35 kOe, suggesting the existence of possible glassy phase in the AF phase. A broad peak in $δ$ and $χ^{\prime \prime}$ at $H \geq$ 20 kOe for $T_{N}(c=0.8,H) \leq T \leq T_{N}(c=1,H=0)$ (= 26.4 K) suggests the existence of the Griffiths phase.

description: Current large-scale auto-regressive language models display impressive fluency and can generate convincing text. In this work we start by asking the question: Can the generations of these models be reliably distinguished from real text by statistical discriminators? We find experimentally that the answer is affirmative when we have access to the training data for the model, and guardedly affirmative even if we do not. This suggests that the auto-regressive models can be improved by incorporating the (globally normalized) discriminators into the generative process. We give a formalism for this using the Energy-Based Model framework, and show that it indeed improves the results of the generative models, measured both in terms of perplexity and in terms of human evaluation.

description: War, natural disasters, and other emergencies regularly disrupt children’s education in developing countries. The digital divide has long since affected low-resource and rural schools’ responses to crises that necessitate distance learning, often excluding children in remote and rural parts of countries from internet-dependent online learning programmes. In no place is this truer than in Haiti where, prior to August 2020, political unrest combined with the COVID-19 pandemic caused learners to miss 60% of their scheduled days in the 2019–2020 school year with only 45% of Haitian households having access to a power source, let alone internet or a smart device, that would enable them to participate in online learning. This study presents findings from exploratory research on the readiness of the Haitian education system to withstand crises and the impact of COVID-19 on the system and its learners. Through analyses of secondary data and semi-structured interviews with a variety of education stakeholders, the research reveals gaps in the system’s readiness; identifies key challenges prompted by school closures in Haiti and shares a handful of innovative responses developed to respond to these challenges. Findings indicate that the COVID-19 health crisis has not created the need for educational reform in Haiti, but rather, by exacerbating pre-existing gaps and frailties within the system, the pandemic has heightened the urgency with which educational reform must be pursued. Salient gaps include a significant digital divide, financial instability and inattention to learning adjacent needs such as nutrition and psychosocial health for parents and children alike. While this initial research has exposed a series of significant gaps and inequalities in the Haitian education system, moving forward, more comprehensive research is needed to determine how such inequalities can be most effectively addressed. Although the Haitian government has a key role to play in addressing these inequalities, findings from this study reveal that governmental responses to COVID-19 school closures and broader digital learning inequalities were ineffective in their reach and did not reflect the majority of Haitian learners and their families’ realities. Findings also identify numerous innovations and assets on the part of non-governmental actors striving to address these gaps. However, these mechanisms were limited in scope and lacked the coordination among one another and the government that would be required to have scalable or measurable impact. Therefore, more research is needed to determine what the most successful mechanisms for addressing inequalities in the Haitian education system are and how they can be most effectively leveraged and scaled to create a more resilient education system moving forward.

description: In this investigation, the extract of Rhus coriaria utilized for preparation of Fe3O4 nanoparticle using a green approach. This method is clean, non-toxic and eco-friendly. The green synthesized nano-catalyst was described by means of SEM, EDX, elemental-mapping point exploration, X-ray diffraction, FT-IR, and UV-Vis analysis methods. The biosynthesized magnetite nanoparticles are affordable and reusable. Accordingly, this allows Fe3O4 nanoparticle catalyst to be utilized in the synthesizing of some new 2-naphthol bis-Betti bases by condensation of substituted aromatic aldehydes, 2-naphthol and p-phenylenediamine by one-pot process reaction. The products have been described using FT-IR, 1H-NMR, 13C-NMR, and mass-spectral data. In vitro anti-bacterial and anti-fungi evaluation of bis Betti bases were achieved against gram-positive and gram-negative bacterial strain by means of the well diffusion method. It has been observed that some of these bis Betti bases possess potent anti-bacterial characteristics against these bacteria.

description: The United Nations (UN) Mission Security Office has a sub-unit who does the daily radio check to know whether staff member(s) are present/absent at any given time within the mission area. It is the Security Office's responsibility to know the staff member(s) and other personnel’s accommodation location and even movement from one team-site to another team-site in the mission. The daily radio check helps the security process, since radio communication is primarily a means to receive and disseminate information in a timely and effective manner to multiple users in times of emergencies like crises. Furthermore, it is a link between the various entities, sectors, and regional offices of a mission. Personnel traveling out of their designated duty station are to notify relevant radio room in duty station of their absence and to be excluded from daily radio check during dates provided. Similarly, those that are traveling back and arriving in the mission area, are to be included in the daily radio check during the stated period of their stay. But the manual logging and lack of significant data and other information needed is becoming problematic. The Security Deployment Tracking System (SDTS) aims to assist Security Officials to keep up-to-date information related to staff member(s) and other personnel within the Security System. The out-of-date process of monitoring staff member(s) and other personnel was transformed in having efficient information over the web-based application that allow quick saving of data, updating of data, extracting useful data
 for reporting purposes and an email notification to those who doesn’t do the daily radio check within the time-range specified to do it. This email notification is filtered to certain criteria to avoid alert and email overload.

description: The hierarchical nature of galaxy formation suggests that a supermassive black hole binary could exist in our galactic center. We propose a new approach to constraining the possible orbital configuration of such a binary companion to the galactic center black hole Sgr A* through the measurement of stellar orbits. Focusing on the star S0-2, we show that requiring its orbital stability in the presence of a companion to Sgr A* yields stringent constraints on the possible configurations of such a companion. Furthermore, we show that precise measurements of {\it time variations} in the orbital parameters of S0-2 could yield stronger constraints. Using existing data on S0-2 we derive upper limits on the binary black hole separation as a function of the companion mass. For the case of a circular orbit, we can rule out a 10^5 M_sun companion with a semimajor axis greater than 170 astronomical units or 0.8 mpc. This is already more stringent than bounds obtained from studies of the proper motion of Sgr A*. Including other stars orbiting the galactic center should yield stronger constraints that could help uncover the presence of a companion to Sgr A*. We show that a companion can also affect the accretion process, resulting in a variability which may be consistent with the measured infrared flaring timescales and amplitudes. Finally, if such a companion exists, it will emit gravitational wave radiation, potentially detectable with LISA.

description: This article discusses the change in the relationship between natura and ars that occurred when Cartesian language theories penetrated conceptions of rhetoric in France during the 17th century. In part one, the article considers the reception of Descartes by the French universities and collèges in order to explore what I call the epistemic transfer between Aristotelianism and the new Cartesian philosophy. The focus then shifts to Bernard Lamy’s conception of rhetoric as presented in his principal work De l’art de parler (1675). Based upon the Cartesian theory of passions, Lamy’s book redefines rhetoric in a way that has been labelled in current research as a ‘grammar of affects’. The fundamentals of the ars rhetorica are thus substantially altered, however without eliminating the power of the rhetorical tradition. The third section turns to the prize contests of the French academies in the 18th century in order to show the extent to which the transformation of rhetorical theory affected the broader practice of eloquence. Moreover, the rhetorical prize contests demonstrate an explicit reflection on the diverging modes of knowledge production that are essential, on the one hand, to the exact sciences and, on the other, to the textual tradition. Particularly striking is the critique of scientific method that was developed by the defenders of rhetoric in the concours académique.

description: Metal-insulator (MI) transitions in correlated electron systems have long been a central and controversial issue in material science. Vanadium dioxide (VO2) exhibits a first-order MI transition at 340 K. For more than half a century, it has been debated whether electronic correlation or the structural instability due to dimerised V ions is the more essential driving force behind this MI transition. Here, we show that an ultrahigh magnetic field of 500 T renders the insulator phase of tungsten (W)-doped VO2 metallic. The spin Zeeman effect on the d electrons of the V ions dissociates the dimers in the insulating phase, resulting in the delocalisation of electrons. Because the Mott-Hubbard gap essentially does not depend on the spin degree of freedom, the structural instability is likely to be the more essential driving force behind the MI transition.

description: Time is treated as a fundamental parameter in virtually every physical theory, yet its ontological status remains unresolved. It appears in equations as an external index, not as a measurable observable, and it resists definition beyond its functional role in tracking change. This paper challenges the necessity of time in quantum mechanics by proposing a recursion-based reformulation of the Schrödinger equation. By replacing the continuous time parameter with a discrete recursive step operator, we demonstrate—through numerical simulation—that quantum evolution proceeds identically, preserving probability density, coherence, and dynamical behaviour. This functional equivalence suggests that time, at least in the context of non-relativistic quantum dynamics, may be conceptually redundant. The results invite a re-examination of time’s assumed fundamentality and open the door to a structurally recursive ontology of physical law.

description: Recently, the interest and support for projects that promote teachers’ social and emotional competencies (SEC) and well-being is increasing world-wide, partly as a result of the growing recognition of the importance of teacher’s SEC and well-being to effective classroom management and positive classroom climate. This article employs a mixed-method approach to assess the effects of the El Salvadorian Integrated Systems of Full-Time Inclusive Schools (SI-EITP), which offers in-service teacher professional development (TPD) combined with a socioemotional learning intervention, on teacher well-being. Findings from the cluster-randomized controlled trial with no baseline show null results for most teacher well-being outcomes analyzed. Interviews suggest limited effects on teachers’ mindfulness and emotion regulation and indicate that teachers’ participation in TPD was potentially increasing their stress levels and emotion exhaustion. We recommend that TPD program designs consider how the delivery mode and intensity may influence teachers’ stress.
