description: The nitrogen (N) budget of the seagrass Thalassia testudinum was examined with respect to inorganic-N acquisition and the effects of sediment NH₄⁺ enrichment on two distinct populations in south Texas. The two populations exhibit different biomass allocation patterns at Corpus Christi Bay (CCB) and lower Laguna Madre (LLM): plants at CCB have a higher above-ground biomass while plants at LLM have a higher below-ground biomass. Ambient sediment pore water NH₄⁺ concentrations at CCB (ca. 100 μM) were significantly higher than at LLM (ca. 30 μM). Therefore, it was hypothesized that 1) differences in biomass allocation are a result of the differential sediment N availability, 2) sediment NH₄⁺ enrichment will affect growth, leaf morphology and tissue nutritional content of T. testudinum to a greater degree at low sediment N conditions, and 3) the relative contributions by leaf and root tissues to total N acquisition will differ between the two study sites. To examine the effects of sediment NH₄⁺ enrichment, the seagrass bed sediments were fertilized with commercial N fertilizer, and changes in production, biomass, leaf morphology, tissue nutritional content and carbon (C) reserves were monitored. Additionally, N uptake by leaves and roots of T. testudinum from the two sites were measured seasonally. After fertilization, leaf production rates and shoot height at LLM increased to reach levels equivalent to CCB. However, sediment NH₄⁺ enrichment had little effect on production and leaf size of T. testudinum at CCB. These results suggest that sediment N availability at LLM limits seagrass production. Rhizome non-structural carbohydrates (NSC) decreased in response to sediment NH₄⁺ enrichment during the early periods of the experiment which suggests that C was reallocated from rhizome to leaf tissues to support the stimulated leaf growth. Thus, the NH₄⁺ enrichment affected concentration and allocation of C as well as N. Root NH₄⁺ uptake accounted for about 52 % of total N acquisition, while leaf NH₄⁺ uptake contributed about 38 % and leaf NO₃⁻ uptake accounted for the remaining 10 % at both sites. The high biomass, chlorophyll, and C content in leaf tissues at CCB and the high biomass, C and NSC content in rhizome tissues at LLM demonstrated that plants responded to high sediment N conditions by enhancing leaf function, and to low N conditions by enhancing function of below-ground tissues

A dedicated small add-on module with single-photon detection, time-tagging and classical communication capabilities would enable us to perform the first-ever quantum optics experiments in space. We present preliminary design concepts for the ground and flight segments and study the feasibility of the intended mission scenario.

description: When it comes to the topic of apartment sizes, planners and local authorities should keep this old adage to the forefront of their minds: less is not more. Ireland’s size standards for residential housing have tended to followBritain’s since about the 1940s. The UK has been producing ever-smaller units and with, in effect, no minimum national standard, it has the smallest homes in western Europe. This is not a trend we need to follow. Minimum space standards for a one-bedroomapartment in Dublin reduced from 484 sq ft in 1961 to 344 sq ft in 1987—and finally up to a more habitable 592 sq ft in 2011. The damage had been done, with undersized units already having been built, but better late than never.

description: We study the action of the dilatation operator on the basis of local operators constructed from the elements of the walled Brauer algebra, with non-planar corrections fully taken into account. We will see that the operator mixing can be neatly expressed in terms of the irreducible representations of the algebra. In particular we focus on a role of the integer that determines the number of boxes in the representations.

description: One-directional traffic on two-lanes is modeled in the framework of a spring-block type model. A fraction $q$ of the cars are allowed to change lanes, following simple dynamical rules, while the other cars keep their initial lane. The advance of cars, starting from equivalent positions and following the two driving strategies is studied and compared. As a function of the parameter $q$ the winning probability and the average gain in the advancement for the lane-changing strategy is computed. An interesting phase-transition like behavior is revealed and conclusions are drawn regarding the conditions when the lane changing strategy is the better option for the drivers.

Breakup corrections to the ${}^3$He beam polarization measurements at the future BNL Electron Ion Collider

description: Requirements for hadron polarimetry at the future Electron-Ion Collider (EIC) include measurements of absolute ${}^3\text{He} (h)$ beam polarization with systematic uncertainties better than $σ^\text{syst}_P/P\lesssim1\%$. Due to the successful use, since 2005, of the polarized hydrogen jet target polarimeter (HJET) to measure proton beam polarization at the Relativistic Heavy Ion Collider (RHIC), the HJET technique promises to be suitable for the ${}^3\text{He}$ polarimetry at EIC. For that, however, one needs to know the ratio of the $h^\uparrow{p}$ and $p^\uparrow{h}$ analyzing powers. For elastic scattering, this ratio can be evaluated with sufficient accuracy if $p^\uparrow{p}$ analyzing power is precisely known. In this paper, the deuteron beam data acquired at HJET in RHIC Run 16 was used to evaluate corrections to the measured helion beam polarization due to the ${}^3\text{He}$ breakup. The breakup effect was found to be negligible if the ratio of the beam and target (jet) single spin asymmetries are concurrently measured to determine the ${}^3\text{He}$ beam polarization.

description: We fit the most updated broadband spectral energy distribution from radio to X-rays for NGC 4258 with a coupled accretion-jet model that surrounding a Kerr black hole (BH), where both the jet and the warped H_2O maser disk are assumed to be triggered by a spinning BH through Blandford-Znajek mechanism and Bardeen-Petterson effect respectively. The accretion flow consists with an inner radiatively inefficient accretion flow (RIAF) and an outer truncated standard thin disk, where the transition radius R_tr~3*10^3Rg for NGC 4258 based on the width and variability of its narrow Fe K$α$ line. The hybrid jet formation model, as a variant of Blandford-Znajek model, is used to model the jet power. Therefore, we can estimate the accretion rate and BH spin through the two observed quantities--X-ray emission and jet power, where the observed jet power is estimated from the low-frequency radio emission. Through this method, we find that the BH of NGC 4258 should be mildly spinning with dimensionless spin parameter a_*=0.7\pm0.2. The outer thin disk mainly radiates at near infrared waveband and the jet contributes predominantly at radio waveband. Using above estimated BH spin and the inferred accretion rate at the region of the maser disk based on the physical existence of the H_2 O maser, we find that the warp radius is ~8.6*10^4 R_g if it is driven by the Bardeen-Petterson effect, which is consistent with the observational result very well.

We conclude by describing asymptotic behavior of solutions to the diffusion problem.

description: We review our studies on Bose and Fermi superfluids of cold atomic gases in optical lattices at zero temperature. Especially, we focus on superfluid Fermi gases along the crossover between the Bardeen-Cooper-Schrieffer (BCS) and the Bose-Einstein condensate (BEC) states, which enable us to study the Bose and the Fermi superfluids in a unified point of view. We discuss basic static and long-wavelength properties (such as the equation of state, incompressibility, and effective mass), energetic stability, and energy band structures of the superfluid Fermi gases in an optical lattice periodic along one spatial direction. The periodic potential causes pairs of atoms to be strongly bound, and this can affect the static and long-wavelength properties and the stability of the superflow. Regarding the band structure, a peculiar loop structure called "swallowtail" can appear in superfluid Fermi gases and in the Bose case, but the mechanism of emergence in the Fermi case is very different from that in bosonic case. Other quantum phases that the cold atomic gases in optical lattices can show are also briefly discussed based on their roles as quantum simulators of Hubbard models.

description: In the framework of a stochastic picture for the one-dimensional branching Brownian motion, we compute the probability density of the number of particles near the rightmost one at a time $T$, that we take very large, when this extreme particle is conditioned to arrive at a predefined position $x_T$ chosen far ahead of its expected position $m_T$. We recover the previously-conjectured fact that the typical number density of particles a distance $Δ$ to the left of the lead particle, when both $Δ$ and $x_T-Δ-m_T$ are large, is smaller than the mean number density by a factor proportional to $e^{-ζΔ^{2/3}}$, where $ζ$ is a constant that was so far undetermined. Our picture leads to an expression for the probability density of the particle number, from which a value for $ζ$ may be inferred.

description: This paper explains the anomalous magnetic moment for all elementary particles and composite particles (such as the proton). The special case regarding the Muon anomaly is addressed. It also presents a summary of the issues in accurately measuring the magnetic dipole moment for elementary particles. The explanation provided involves simple math and probabilities. It is not complex, such as Yang-Mills and related theories. In summary, there is no anomaly. The measurement of the magnetic moment is a time-averaged value for 16 different particles. Areas for further research are suggested.
For example, in measuring the magnetic moment of an electron, it is assumed there is only one kind of electron. In fact, there are 16 different types of electrons --  4 charges X 4 spins.  To properly measure the magnetic moment for a single particle – the data must be sampled much faster, at 2.2 THz or faster.
Bifurcations in Boltzmann-Langevin One Body dynamics for fermionic systems

description: We investigate the occurrence of bifurcations in the dynamical trajectories depicting central nuclear collisions at Fermi energies. The quantitative description of the reaction dynamics is obtained within a new transport model, based on the solution of the Boltzmann-Langevin equation in three dimensions, with a broad applicability for dissipative fermionic dynamics. Dilute systems formed in central collisions are shown to fluctuate between two energetically favourable mechanisms: reverting to a compact shape or rather disintegrating into several fragments. The latter result can be connected to the recent observation of bimodal distributions for quantities characterising fragmentation processes and may suggest new investigations.

description: Let $U_5$ be the tournament with vertices $v_1$, ..., $v_5$ such that $v_2 \rightarrow v_1$, and $v_i \rightarrow v_j$ if $j-i \equiv 1$, $2 \pmod{5}$ and ${i,j} \neq {1,2}$. In this paper we describe the tournaments which do not have $U_5$ as a subtournament. Specifically, we show that if a tournament $G$ is "prime"---that is, if there is no subset $X \subseteq V(G)$, $1 < |X| < |V(G)|$, such that for all $v \in V(G) \backslash X$, either $v \rightarrow x$ for all $x \in X$ or $x \rightarrow v$ for all $x \in X$---then $G$ is $U_5$-free if and only if either $G$ is a specific tournament $T_n$ or $V(G)$ can be partitioned into sets $X$, $Y$, $Z$ such that $X \cup Y$, $Y \cup Z$, and $Z \cup X$ are transitive. From the prime $U_5$-free tournaments we can construct all the $U_5$-free tournaments. We use the theorem to show that every $U_5$-free tournament with $n$ vertices has a transitive subtournament with at least $n^{\log_3 2}$ vertices, and that this bound is tight.

We find that the U(1)\times U(1) solutions become unstable to forming non-Abelian hair. These configurations emerge as zero modes of the Abelian solutions at critical temperature and a critical (nonvanishing) ratio of the electric charges and can be viewed as holographic p-wave superfluids.

Feasibility study for precisely measuring the EIC ${}^3$He beam polarization with the Polarized Atomic Hydrogen Gas Jet Target polarimeter at RHIC

Publisher: name: arXiv
Year: 2022
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The Polarized Atomic Hydrogen Gas Jet Target polarimeter (HJET) is used to measure the absolute proton beam polarization, $σ_P^\text{syst}/P\!\lesssim\!0.5\%$, at the Relativistic Heavy Ion Collider. Here I consider the possibility of employing HJET to measure the ${}^3\text{He}$ ($h$) beam polarization at the Electron-Ion Collider (EIC). The dominant contribution to the ratio of the $h^\uparrow{p}$ and $p^\uparrow{h}$ analyzing powers, which is needed for such measurements, can be easily calculated using well-known values of the proton and helion magnetic moments, but some corrections should be applied to achieve the required accuracy. It was found that corrections due to absorption and ${}^3\text{He}$ breakup effectively cancel in the ratio and a correction due to hadronic spin-flip amplitudes can be derived from the proton beam measurements. As a result, the anticipated systematic uncertainty in the measured ${}^3\text{He}$ beam polarization can satisfy the EIC requirement $σ_P^\text{syst}/P\!\lesssim\!1\%$.

description: This paper deals with the problem of estimating all the unknown parameters of geometric mixed subfractional Brownian motion, which is widely used in practice, such as in physical systems, finance and economics. Geometric mixed subfractional Brownian motion satisfies a stochastic differential equation driven by a mixed subfractional Brownian motion, which is a linear combination of a fractional Brownian motion and an independent subfractional Brownian motion. Firstly, we give the estimators for the unknown parameters by the methods of p-th power variation for the Gaussian process and the maximum likelihood method. Then, we prove the asymptotic properties of the estimators. Secondly, the Monte Carlo method is used for simulation. The results show that the method used in this paper is effective and reliable. Finally, we empirically study the financial market with actual financial data for three stocks, showing the superiority of the model in the paper over other classical models.

By solving the heat transport equation in the steady-state regime between metals or polar materials we highlight a flux saturation mechanism for the radiative transfer even without non-local effect. In the case of polar materials this saturation occurs in the separation distances range of 1 to 10 nm which can be experimentally explored.

description: We report enhanced sub-Doppler cooling of the bosonic atoms of $^{39}$K facilitated by formation of dark states tuned for the Raman resonance in the $Λ-$configuration near the D1 transition. Temperature of about 12 $μ$K is achieved in the two stage D2-D1 molasses and spans a very large parameter region where quantum interference persists robustly. We also present results on enhanced radiation heating with sub-natural linewidth (0.07$Γ$) and signature Fano like profile of a coherently driven 3-level atomic system. The Optical Bloch Equations relevant for the three-level atom in bichromatic light field is solved with the method of continued fractions to show that cooling occurs only for a small velocity class of atoms, emphasizing the need for pre-cooling in D2 molasses stage.

A Novel Neural Network Training Method for Autonomous Driving Using Semi-Pseudo-Labels and 3D Data Augmentations

description: Training neural networks to perform 3D object detection for autonomous driving requires a large amount of diverse annotated data. However, obtaining training data with sufficient quality and quantity is expensive and sometimes impossible due to human and sensor constraints. Therefore, a novel solution is needed for extending current training methods to overcome this limitation and enable accurate 3D object detection. Our solution for the above-mentioned problem combines semi-pseudo-labeling and novel 3D augmentations. For demonstrating the applicability of the proposed method, we have designed a convolutional neural network for 3D object detection which can significantly increase the detection range in comparison with the training data distribution.

description: In recent years there has been a growing interest in the field of Casimir wormhole. In classical general relativity (GR), it is known that the null energy condition (NEC) has to be violated to have a wormhole to be stable. The Casimir effect is an experimentally verified effect that is caused due to the vacuum field fluctuations in quantum field theory. Since the Casimir effect provides the negative energy density, thus this act as an ideal candidate for the exotic matter needed for the stability of the wormhole. In this paper, we study the Casimir effect on the wormhole geometry in modified symmetric teleparallel gravity or $f(Q)$ gravity, where the non-metricity scalar $Q$ drives the gravitation interaction. We consider three systems of the Casimir effect such as (i) two parallel plates, (ii) two parallel cylindrical plates, and (iii) two-sphere separated by a large distance to make it more experimentally feasible. Further, we studied the obtained wormhole solutions for each case with energy conditions at the wormhole throat with radius $r_0$ and found that some arbitrary quantity violates the classical energy conditions at the wormhole throat. Furthermore, the behavior of the equation of state (EoS) is also analyzed for each case. Finally, we investigate the stability of the obtained Casimir effect wormhole solutions with the generalized Tolman-Oppenheimer-Volkoff (TOV) equation.

description: We present deep 450um and 850um observations of a large, uniformly covered 394arcmin^2 area in the COSMOS field obtained with the SCUBA-2 instrument on the James Clerk Maxwell Telescope (JCMT). We achieve root-mean-square noise values of 4.13mJy at 450um and 0.80mJy at 850um. The differential and cumulative number counts are presented and compared to similar previous works. Individual point sources are identified at >3.6sigma significance, a threshold corresponding to a 3-5% sample contamination rate. We identify 78 sources at 450um and 99 at 850um, with flux densities S450=13-37mJy and S850=2-16mJy. Only 62-76% of 450um sources are 850um detected and 61-81% of 850um sources are 450um detected. The positional uncertainties at 450um are small (1-2.5") and therefore allow a precise identification of multiwavelength counterparts without reliance on detection at 24um or radio wavelengths; we find that only 44% of 450um-selected galaxies and 60% of 850um-sources have 24um or radio counterparts. 450um-selected galaxies peak at =1.95+-0.19 and 850um=selected galaxies peak at =2.16+-0.11. The two samples occupy similar parameter space in redshift and luminosity, while their median SED peak wavelengths differ by ~10-50um (translating to deltaTdust =8-12K, where 450um-selected galaxies are warmer). The similarities of the 450um and 850um populations, yet lack of direct overlap between them, suggests that submillimeter surveys conducted at any single far-infrared wavelength will be significantly incomplete (~>30%) at censusing infrared-luminous star formation at high-z.

description: We propose two frequency-domain filters to analyze ringdown signals of binary black hole mergers. The first rational filter is constructed based on a set of (arbitrary) quasi-normal modes (QNMs) of the remnant black holes, whereas the second full filter comes from the transmissivity of the remnant black holes. The two filters can remove corresponding QNMs from original time-domain ringdowns, while changing early inspiral signals in a trivial way - merely a time and phase shift. After filtering out dominant QNMs, we can visualize the existence of various subdominant effects. For example, by applying our filters to a GW150914-like numerical relativity (NR) waveform, we find second-order effects in the (l = 4, m = 4), (l = 5, m = 4) and (l = 5, m = 5) harmonics; the spherical-spheroidal mixing mode in the (l = 2,m = 2) harmonic; and a mixing mode in the (l = 2,m = 1) harmonic due to a gravitational recoil. In another NR simulation where two component spins are anti-aligned with the orbital angular momentum, we also find retrograde modes. The filters are sensitive to the remnant properties (i.e., mass and spin) and thus have a potential application to future data analyses and parameter estimations. We also investigate the stability of the full filter. Its connection to the instability of QNM spectra is discussed.

Affective Reactions to Uncertainty as Driven by Past Experiences, Personality, and Perceived Valence

description: The assumption that uncertainty is inherently threatening which underlies decades of research belies the fact that people rarely react negatively to uncertain situations about which they do not care, and that some are excited by uncertainty. I propose that affective reactions to uncertainty are driven not by uncertainty itself, but by people’s expectations of positive and negative outcomes to personally relevant uncertain situations. I find that positive past experiences predict higher optimism and higher resilience, both of which predict higher tolerance of uncertainty and more positive perceptions of uncertain events. I also find that negative past experiences predict higher pessimism and lower resilience, both of which predict higher intolerance of uncertainty and more negative perceptions of uncertain events. The second study suggests that optimistic people are more likely to approach, rather than avoid, uncertainty. The third study finds that mindfulness training, which emphasizes non-attachment to outcomes, results in more neutral reactions to uncertainty. Theoretical and practical implications are discussed.
Mixed Bubbles in a one-dimensional Bose-Bose mixture

description: We investigate a Bose-Bose mixture across the miscible-immiscible phase transition governed by quantum fluctuations in one dimension. We find the recently predicted so-called mixed bubbles as ground states close to the mean-field miscible-immiscible threshold. These bubbles form a pocket of miscibility, separated by one of the components. The collective excitations reflect the symmetry breaking resulting from the bubble formation. The partial miscibility of the system allows for persistent currents in an annular confinement. Intriguingly, the mixed bubble acts like an intrinsic weak link, connecting the rotational behavior of the mixed bubble state to current efforts in atomtronic applications.

description: The evolution of financial technology (FinTech) globally is reshaping the banking system, including Tanzania’s financial sector. This study examines the influence of FinTech on Tanzania’s banking sector, particularly its impact on non-performing loans. Using a financial technology index alongside bank-specific and macroeconomic variables, the analysis covers data from 30 Tanzanian commercial banks spanning 2010 to 2021. Employing a two-step system, a Generalized Method of Moments, the study tests the hypotheses and provides robust findings. The results reveal that FinTech significantly reduces non-performing loans across all bank categories, with the strongest effects observed in small banks, followed by medium and large banks. This indicates that advancements in FinTech improve credit risk management and reduce loan default rates. Conversely, a cost-to-income ratio and a high loan-to-deposit ratio increase non-performing loans, particularly in medium-sized banks. These findings have critical implications for policymakers and practitioners. Policymakers should prioritize fostering a supportive regulatory environment to encourage FinTech integration, particularly among small and medium banks. Bank managers are encouraged to leverage FinTech innovations to enhance credit risk management and operational efficiency. The study highlights the transformative potential of FinTech in managing credit risk and driving sustainable growth in Tanzania’s banking sector. This study examines the impact of FinTech adoption on non-performing loans (NPLs) in Tanzanian commercial banks from 2010 to 2021 using a FinTech index and macroeconomic variables. Employing a two-step system Generalized Method of Moments (GMM), the findings reveal that FinTech significantly reduces NPLs, particularly in small and medium-sized banks, enhancing credit risk management. The study highlights the need for a supportive regulatory environment to foster FinTech Development and improve banking efficiency. By demonstrating FinTech’s role in mitigating credit risk, this research offers valuable insights for policymakers and bank managers in driving financial stability and sustainable growth.

description: Cancer is a major public health problem and the second-leading cause of death in the world. Colorectal cancer (CRC) is the third most diagnosed cancer in the U.S. CRC is highly associated with daily diet and eating patterns. A plant-based diet rich in phytochemicals has been known to be protective against the initiation and progression of CRC occurrence. The hop plant, a key ingredient in beer, contains a diverse form of bioactive compounds that possess biological benefits in tumorigenesis. Xanthohumol (XN), the most abundant prenylated flavonoid, has been used over the years to treat a broad range of chronic diseases such as diabetes, obesity, and cancer. Several derivatives of XN, including isoxanthohumol (IXN), 8-prenylnaringenin (8-PN), and tetrahydroxanthohumol (TXN), possess similar and greater biological benefits compared to XN. While XN's anti-cancer properties are well known, the effects of these derivatives have not been evaluated in human CRC models. Our study aimed to test the cancer-suppressive activities of these derivatives and elucidate anti-cancer mechanisms using human adenocarcinoma CRC cells. The results indicate that four hop compounds (XN, IXN, 8-PN, and TXN) significantly suppressed the proliferation of different types of human CRC cell lines. We selected TXN and XN for further studies due to their more significant and promising anti-proliferative activity compared with other forms. Flow cytometry analysis indicated that TXN and XN led to significant induction of S-phase and G2/M-phase arrest. An apoptotic assay showed a huge induction of early and late apoptosis in cells treated with TXN and XN at doses of 12 µM and 18 µM. Western blot data indicate that TXN and XN induce the cleavage of PARP and increase the expression of CHOP, IRE1α, and ATF4, indicating activation of caspase-dependent apoptosis and ER stress. In addition, a dose-dependent increase in intracellular ROS was observed in cells treated with 12 and 18 µM of TXN and XN, affecting mitochondrial dysfunction. Taken together, our current study proposes an anti-cancer mechanism by TXN and XN through their action on the induction of ROS release and mitochondrial dysfunction, ER stress, and apoptosis in human CRC cells.
