description: Signal of the rare radiative decay PHI--->ETA+PI0+GAMMA was observed in the SND experiment at VEPP-2M electron-positron collider.The result is based on the analysis of data, corresponding to a total integrated luminosity of 4 pb^{-1}, or 8x10^6 PHI mesons produced. The measured branching ratio of PHI--->ETA+PI0+GAMMA decay is equal to (0.83+-0.23)x10^{-4}.

description: We consider the steady fractional Schrödinger equation $L u + V u = f$ posed on a bounded domain $Ω$; $L$ is an integro-differential operator, like the usual versions of the fractional Laplacian $(-Δ)^s$; $V\ge 0$ is a potential with possible singularities, and the right-hand side are integrable functions or Radon measures. We reformulate the problem via the Green function of $(-Δ)^s$ and prove well-posedness for functions as data.If $V$ is bounded or mildly singular a unique solution of $(-Δ)^s u + V u = μ$ exists for every Borel measure $μ$. On the other hand, when $V$ is allowed to be more singular, but only on a finite set of points, a solution of $(-Δ)^s u + V u = δ_x$, where $δ_x$ is the Dirac measure at $x$, exists if and only if $h(y) = V(y) |x - y|^{-(n+2s)}$ is integrable on some small ball around $x$. We prove that the set $Z = \{x \in Ω: \textrm{no solution of } (-Δ)^s u + Vu = δ_x \textrm{ exists}\}$ is relevant in the following sense: a solution of $(-Δ)^s u + V u = μ$ exists if and only if $|μ| (Z) = 0$. Furthermore, $Z$ is the set points where the strong maximum principle fails, in the sense that for any bounded $f$ the solution of $(-Δ)^s u + Vu = f$ vanishes on $Z$.

description: I illustrate a general formalism based upon the subtraction method for the calculation of next-to-leading order QCD cross sections for any number of jets in any type of hard collisions. I discuss the implementation of this formalism in a numerical program which generates partonic kinematical configurations with an appropriate weight, thus allowing the definition of arbitrary jet algorithms and cuts matching the experimental setup at the last step of the computation. I present results obtained with computer codes which calculate one-jet and two-jet inclusive quantities in photon-hadron and hadron-hadron collisions.

description: The effect of the Hubbard interaction among conduction electrons on the double exchange model is investigated in a ferromagnetic metallic phase. Applying iterative perturbation theory to the Hubbard interaction within dynamical mean field theory, we calculate the one-particle spectral function and the optical conductivity, in which coherent-potential approximation is further used to treat the ferromagnetic Hund coupling between conduction electrons and localized spins. Identifying the decrease of the magnetization for the localized spin with the increase of the temperature, we discuss the temperature dependence of the one-particle spectrum and the optical conductivity. It is found that the interplay between the Hund coupling and the Hubbard interaction dramatically changes the spectral function, while it is somehow obscured in the optical conductivity.

description: Wavelengths in the telecommunication window (~1.25-1.65 microns) are ideal for quantum communication due to low transmission loss in fiber networks. To realize quantum networks operating at these wavelengths, long-lived quantum memories that couple to telecom-band photons with high efficiency need to be developed. We propose coupling neutral ytterbium atoms, which have a strong telecom-wavelength transition, to a silicon photonic crystal cavity. Specifically, we consider the 3P0-3D1 transition in neutral 171Yb to interface its long-lived nuclear spin in the metastable 3P0 'clock' state with a telecom-band photon at 1.4 microns. We show that Yb atoms can be trapped using a short wavelength (~470 nm) tweezer at a distance of 350 nm from the silicon photonic crystal cavity. At this distance, due to the slowly decaying evanescent cavity field at a longer wavelength, we obtain a single-photon Rabi frequency of g/(2pi)~100 MHz and a cooperativity of C~47 while maintaining a high photon collection efficiency into a single mode fiber. The combination of high system efficiency, telecom-band operation, and long coherence times makes this platform well suited for quantum optics on a silicon chip and long-distance quantum communication.

description: A new class of analytic charged spherically symmetric black hole solutions, which behave asymptotically as flat or (A)dS spacetimes, is derived for specific classes of $f(R)$ gravity, i.e., $f(R)=R-2α\sqrt{R}$ and $f(R)=R-2α\sqrt{R-8Λ}$, where $Λ$ is the cosmological constant. These black holes are characterized by the dimensional parameter $α$ that makes solutions deviate from the standard solutions of general relativity. The Kretschmann scalar and squared Ricci tensor are shown to depend on the parameter $α$ which is not allowed to be zero. Thermodynamical quantities, like entropy, Hawking temperature, quasi-local energy and the Gibbs free energy are calculated. From these calculations, it is possible to put a constrain on the dimensional parameter $α$ to have $0

description: The purpose of this study was to look into the inclusion of disabled students in
higher education institutions. A quantitative technique was utilized in conjunction
with a cross-sectional survey design. A total of 246 SWDs were chosen from five
Ethiopian public HEIs using a stratified proportionate random sampling technique.
Frequency, percentage, mean, standard deviation, correlation, one-sample t-test,
multiple regressions, Independent samples t-test, and One Way ANOVA were used
to examine data acquired through a college student experience questionnaire. The
pupils were found to be enrolled in the institutions, according to the findings. When
compared to male students, female students scored higher on inclusion. Pupils
who were blind were more included than students who were deaf or had physical
limitations. However, the pupils’ inclusion does not seem to be affected by their year
level.The conclusion is that, despite the fact that inclusion has been discussed in
disability literature for a long time, there is no scale to quantify it in higher education.
As a result, the advice is that a scale be devised, and that males who are deaf and
have physical limitations, for example, be assisted by institutions.

The antiferromagnetic Neel temperature T_N is determined from the specific heat maximum in combination with finite-size scaling of the magnetic structure factor. Our results interpolate smoothly between the asymptotic solutions for weak and strong coupling, respectively, in contrast to previous QMC simulations. The location of the metal-insulator transition in the paramagnetic phase above T_N is determined using the electronic compressibility as criterion.

description: The discovery of the top quark in 1995, by the CDF and D0 collaborations at the Fermilab Tevatron, marked the dawn of a new era in particle physics. Since then, enormous efforts have been made to study the properties of this remarkable particle, especially its mass and production cross section. In this article, we review the status of top quark physics as studied by the two collaborations using the p-pbar collider data at sqrt(s) = 1.8 TeV. The combined measurement of the top quark mass, m_t = 173.8 +- 5.0 GeV/c^2, makes it known to a fractional precision better than any other quark mass. The production cross sections are measured as sigma (t-tbar) = 7.6 -1.5 +1.8 pb by CDF and sigma (t-tbar) = 5.5 +- 1.8 pb by D0. Further investigations of t-tbar decays and future prospects are briefly discussed.

description: We discuss the quantum numbers of domain walls of minimal length induced by doping Mott insulators, carefully distinguishing between holon and hole walls. We define a minimal wall hypothesis that uniquely correlates the observed spatial structure with the doping level for the low-temperature commensurate insulating state of La$_{2-x}$Ba$_x$CuO$_4$ and related materials at $x={1\over 8}$. We remark that interesting walls can be supported not only by conventional antiferromagnetic but also by orbital antiferromagnetic (staggered flux phase, $d$-density) bulk order. We speculate on the validity of the minimal wall hypothesis more generally, and argue that it plausibly explains several of the most striking anomalous features of the cuprate high-temperature superconductors.

description: Pole-skipping is a recently discovered signature of many-body quantum chaos in collective energy dynamics. It establishes a precise connection between resummed, all-order hydrodynamics and the underlying microscopic chaos. In this paper, we demonstrate the existence of pole-skipping in holographic conformal field theories with higher-derivative gravity duals. In particular, we first consider Einstein-Hilbert gravity deformed by curvature-squared ($R^2$) corrections and then type IIB supergravity theory with the $α'^3 R^4$ term, where $α'$ is set by the length of the fundamental string. The former case allows us to discuss the effects of leading-order $1/N_c$ corrections (with $N_c$ being the number of colours of the dual gauge group) and phenomenological coupling constant dependence. In Einstein-Gauss-Bonnet theory, pole-skipping turns out to be valid non-perturbatively in the Gauss-Bonnet coupling. The $α'^3 R^4$ deformation enables us to study perturbative inverse 't Hooft coupling corrections ($α'^3 \sim 1 / λ^{3/2}$) in $SU(N_c)$, $\mathcal{N} = 4$ supersymmetric Yang-Mills theory with infinite $N_c$. While the maximal Lyapunov exponent characterising quantum chaos remains uncorrected, the butterfly velocity is shown to depend both on $N_c$ and the coupling. Several implications of the relation between hydrodynamics and chaos are discussed, including an intriguing similarity between the dependence of the butterfly velocity and the ratio of shear viscosity to entropy density on stringy corrections.

description: The efficacy of a specially constructed Gallager-type error-correcting code to communication in a Gaussian channel is being examined. The construction is based on the introduction of complex matrices, used in both encoding and decoding, which comprise sub-matrices of cascading connection values. The finite size effects are estimated for comparing the results to the bounds set by Shannon. The critical noise level achieved for certain code-rates and infinitely large systems nearly saturates the bounds set by Shannon even when the connectivity used is low.

description: We develop an analytical framework to study the synchronization of a quantum self-sustained oscillator to an external signal. Our unified description allows us to identify the resource on which quantum synchronization relies, and to compare quantitatively the synchronization behavior of different limit cycles and signals. We focus on the most elementary quantum system that is able to host a self-sustained oscillation, namely a single spin 1. Despite the spin having no classical analogue, we first show that it can realize the van der Pol limit cycle deep in the quantum regime, which allows us to provide an analytical understanding to recently reported numerical results. Moving on to the equatorial limit cycle, we then reveal the existence of an interference-based quantum synchronization blockade and extend the classical Arnold tongue to a snake-like split tongue. Finally, we derive the maximum synchronization that can be achieved in the spin-1 system, and construct a limit cycle that reaches this fundamental limit asymptotically.

This problem and its siblings can be understood through generating functions with 0/1 coefficients according to whether or not an integer is representable. In the 2-parameter case, this generating function has an elegant closed form, from which many corollaries follow, including a formula for the Frobenius problem. We establish a similar closed form for the generating function indicating all integers with exactly $k$ representations, with similar wide-ranging corollaries.

description: The Hilbert spaces of the edge excitations of several ``paired'' fractional quantum Hall states, namely the Pfaffian, Haldane-Rezayi and 331 states, are constructed and the states at each angular momentum level are enumerated. The method is based on finding all the zero energy states for those Hamiltonians for which each of these known ground states is the exact, unique, zero-energy eigenstate of lowest angular momentum in the disk geometry. For each state, we find that, in addition to the usual bosonic charge-fluctuation excitations, there are fermionic edge excitations. The edge states can be built out of quantum fields that describe the fermions, in addition to the usual scalar bosons (or Luttinger liquids) that describe the charge fluctuations. The fermionic fields in the Pfaffian and 331 cases are a non-interacting Majorana (i.e., real Dirac) and Dirac field, respectively. For the Haldane-Rezayi state, the field is an anticommuting scalar. For this system we exhibit a chiral Lagrangian that has manifest SU(2) symmetry but breaks Lorentz invariance because of the breakdown of the spin statistics connection implied by the scalar nature of the field and the positive definite norm on the Hilbert space. Finally we consider systems on a cylinder where the fluid has two edges and construct the sectors of zero energy states, discuss the projection rules for combining states at the two edges, and calculate the partition function for each edge excitation system at finite temperature in the thermodynamic limit. It is pointed out that the conformal field theories for the edge states are examples of orbifold constructions.

description: The study of global event shape variables can provide sensitive tests of predictions for multijet production in proton-proton collisions. This paper presents a study of several event shape variables calculated using jet four momenta in proton-proton collisions at a centre-of-mass energy of 13 TeV and uses data recorded with the CMS detector at the LHC corresponding to an integrated luminosity of 2.2 fb$^{-1}$. After correcting for detector effects, the resulting distributions are compared with several theoretical predictions. The agreement generally improves as the energy, represented by the average transverse momentum of the two leading jets, increases.

description: I show that the (standard) genetic code exhibits a singularly determinate, rich, and beautiful structure. This result comprises the ﬁrst substantive step in an ongoing projectaiming to devise a formal method (or if you will a ’symbolic language’) adequate to the problem(s) of biological - and speciﬁcally of biomolecular - organization. In any case, the procedure I lay out below is self-contained and sraightforward enough for it to be put forward in a cut-and-dry manner, i.e. as a purely formal - not to say technical - result. In particular, I have deliberately refrained from drawing inferences or raising speculations with regard to the biological signiﬁcance of the sequel. Rather, I content myself with showing that it is highly unlikely that these results are of no biological signiﬁcance whatsoever. Speciﬁcally, I show that the probability that the structure here described is the product of mere chance is several order of magnitude lower than 10^(-17). The question itself, regarding to biological signiﬁcance and implications of the sequel, will need to be addressed and worked out in the context of the more general method. For now, suﬃce it if I manage to convince the reader that what we are looking at here is a genuine, and potentially profound, biological puzzle.

This is done by showing that only incompatible measurements allow for an efficient use of premeasurement information in order to improve the probability of guessing the correct state. Thus, the gap between the guessing probabilities with pre- and postmeasurement information is a witness of the incompatibility of a given collection of measurements. We prove that all linear incompatibility witnesses can be implemented as some state discrimination protocol according to this scheme. As an application, we characterize the joint measurability region of two noisy mutually unbiased bases.

description: AIM: This narrative literature review aims to evaluate the treatment of botulinum toxin compared to Le Fort I orthognathic surgery in patients with a gummy smile. 


METHODS: An electronic search was conducted via PubMed/Medline and Google Scholar using keywords such as "gummy smile", "excessive gingival display", "high smile line", "botulinum toxin treatment and correction", "botox usages" and "orthognathic surgery" for studies published until January 2015. After excluding unrelated items, the initial search yielded 84 articles. Following the exclusion of irrelevant articles based on abstract and title, the full texts of 60 articles were reviewed and included in this study.


RESULTS: Botulinum toxin treatment and Le Fort I osteotomy present distinct advantages and disadvantages. Botulinum toxin serves as an adjunct for correcting excessive gingival display and is gaining popularity due to its minimally invasive nature. However, Le Fort I osteotomy remains the gold standard for correcting vertical maxillary excess in gummy smile patients.


CONCLUSIONS: Both botulinum toxin treatment and Le Fort I osteotomy are essential for correcting different types of gummy smiles. Neither can completely replace the other in the correction of gummy smiles.

Comment on ``Quantum Suppression of Shot Noise in Atom-Size Metallic Contacts''

description: In a recent letter (Phys.Rev.Lett. 82, 1526 (1999)), van den Brom and van Ruitenbeek found a pronounced suppression of the shot noise in atom-size gold contacts with conductances near integer multiples of $G_0=2e^2/h$, revealing unambiguously the quantized nature of the electronic transport. However, the ad hoc model they introduced to describe the contribution of partially-open conductance channels to the shot noise is unable to fit either the maxima or minima of their shot noise data. Here we point out that a model of quantum-confined electrons with disorder quantitatively reproduces their measurements.

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Using data recorded by the CLEO-II detector at CESR, we report the first measurement of the branching fraction for the decay of $τ^-$ into $K^{*-}ην_τ$. The measured branching fraction is (2.9 +- 0.8 +- 0.4) $10^{-4}$. We also measure the inclusive branching fractions without requiring the $K^*$ resonance: $τ^-$ into $K_S π^- ην_τ$, $τ^-$ into $K^- π^0 ην_τ$. The measured branching fractions are (1.10 +- 0.35 +- 0.11) $10^{-4}$, (1.77 +- 0.56 +- 0.71) $10^{-4}$ respectively.

Recycling Debonded Metal Orthodontic Brackets - A Comprehensive Review and Meta-Analysis
Creators: name: Goh, Ming Wei
Publisher: name: Archive of Orofacial Data Science
Year: 2024
Subjects: Orthodontic Brackets
Meta-Analysis
Recycling Techniques
Shear Bond Strength

description: AIM: This work provides orthodontic practitioners with an updated literature review and meta-analysis on the practicality of reusing debonded metal orthodontic brackets. 
METHODS: An electronic search from January 1989 to June 2017 on MEDLINE-PubMed and EBSCOhost Research Databases yielded 63 studies after removing duplicates. Following initial screening, 47 potentially relevant articles were identified. Detailed scrutiny led to the exclusion of 19 studies. The remaining 19 studies were divided into two groups: Group I (same bracket brand and bonding agent) and Group II (different bracket brand and bonding agents). Meta-analysis and sensitivity tests were conducted using RevMan Analysis in Review Manager (version 5.3). 
RESULTS: The mean shear bond strength (SBS) for debonding a new bracket was 10.16 MPa. Five chairside recycling methods were compared: erbium laser, aluminum oxide sandblasting, high-speed grinding, slow-speed grinding, and direct flaming. Average reductions in SBS were 0.65 MPa, 0.89 MPa, 2.82 MPa, 3.49 MPa, and 3.93 MPa, respectively. 
CONCLUSION: Erbium laser recycling is highly efficient, though cost-prohibitive. Chairside aluminum oxide sandblasting with a microetcher offers a cost-effective alternative with comparable SBS. High-speed grinding surpasses slow-speed grinding, but both exhibit less favorable rebonding strength than sandblasting. Direct flaming yields the lowest SBS. Chairside sandblasting emerges as the most practical and economical method for recycling debonded metal orthodontic brackets.

Smile Asymmetry in Patients treated with combined Orthodontics and Orthognathic Surgery
Creators: name: Martins, Sofia
Publisher: name: Archive of Orofacial Data Science
Year: 2024
Subjects: Lip Canting
Smile Extent
Orthognathic Surgery
Facial Landmark Points

description: AIM: The aim of this study was to examine the relationship between lip canting and the extent of a smile, both pre- and post-operatively, in patients who were treated with combined orthodontics and orthognathic surgery. 
METHODS: This study included 90 clinical photographs of 45 patients smiling, both before and after orthognathic surgery. Facial landmark points were traced to compare pre- and post-operative photographs. The data were used to measure the vertical distance of the lips when smiling – lip elevation and the extent of a smile, both before and after surgery. The correlations among canting, the type of surgery, and Angle class were evaluated by a one-way analysis of variance (ANOVA) and multiple comparisons using the Tamhane post hoc test. 
RESULTS: The magnitude of the post-operative extent of a smile was not significantly correlated with lip elevation and changes in lip canting. There were no statistical differences for Angle class I and asymmetric cases, in contrast to Class II and III results regarding the extent of a smile post-operatively. Bimaxillary surgery resulted in significantly broader smiles, and bilateral sagittal split osteotomy resulted in higher lip elevation post-operatively, though not to a significant extent. 
CONCLUSION: Soft tissues, particularly the smiling lip line, are affected by orthognathic surgery and skeletal malocclusion. However, further studies will be needed to better assess and study smile dynamics.

Thermal Boundary Conductance of Two-Dimensional $MoS_{2}$ Interfaces

description: Understanding the thermal properties of two-dimensional (2D) materials and devices is essential for thermal management of 2D applications. Here we perform molecular dynamics simulations to evaluate both the specific heat of $MoS_{2}$ as well as the thermal boundary conductance (TBC) between one to five layers of $MoS_{2}$ with amorphous $SiO_{2}$ and between single-layer $MoS_{2}$ and crystalline $AlN$. The results of all calculations are compared to existing experimental data. In general, the TBC of such 2D interfaces is low, below ~20 $MWm^{-2}K^{-1}$, due to the weak van der Waals (vdW) coupling and mismatch of phonon density of states (PDOS) between materials. However, the TBC increases with vdW coupling strength, with temperature, and with the number of $MoS_{2}$ layers (which introduce additional phonon modes). These findings suggest that the TBC of 2D materials is tunable by modulating their interface interaction, the number of layers, and finding a PDOS-matched substrate, with important implications for future energy-efficient 2D electronics, photonics, and thermoelectrics.

Directly search for Ultra-High Energy WIMPs at IceCube

description: I study the possibility of directly detecting Ultra-high energy (UHE from now on) WIMPs by the IceCube experiment, via the WIMPs interaction with the nuclei in the ice. I evaluate galactic and extragalactic UHE WIMP and astrophysical and atmospheric neutrino event rates at energy range of 10 TeV - 10 PeV. I assume UHE WIMPs $χ$ are only from the decay of superheavy dark matter $ϕ$, that is $ϕ\toχ\barχ$. If the lifetime of superheavy dark matter $τ_ϕ$ is taken to be $5\times10^{21}$s, WIMPs can be detected at energies above O(40-100)TeV in this detection. Since UHE WIMP fluxes are actually depended on $τ_ϕ$, if superheavy dark matter can decay to standard model particles (that is $τ_ϕ$ is constrained to be larger than O($10^{26}$-$10^{29}$)s), UHE WIMPs could not be detected by IceCube.

description: We have developed a new dynamical model of the torus region in active galactic nucleus (AGN), using a three-dimensional radiation hydrodynamics algorithm. These new simulations have the specific aim to explore the role of radiatively-driven outflows, which is hotly debated in current literature as a possible explanation for the observed infrared emission from the polar regions of AGN. In this first paper, we only consider radiative effects induced by the primary radiation from the AGN. The simulations generate a disk & outflow structure that qualitatively agrees with observations, although the outflow is radial rather than polar, likely due to the lack of radiation pressure from hot dust. We find cut-offs between the wind and disk at gas temperatures of 1000 K and dust temperatures of 100 K, producing kinematic signatures that can be used for interpretation of high resolution infrared observations. We also produce line emission maps to aid in the interpretation of recent ALMA observations and future JWST observations. We investigate a number of simulation parameters, and find that the anisotropy of the radiation field is equally important to the Eddington factor, despite the anisotropy often being assumed to have a single sometimes arbitrary form in many previous works. We also find that supernovae can have a small but significant impact, but only at extremely high star formation rates.
