description: We have examined cobalt based valence tautomer molecules such as Co(SQ)$_2$(phen) using density functional theory (DFT) and variational configuration interaction (VCI) approaches based upon a model Hamiltonian. Our DFT results extend earlier work by finding a reduced total energy gap (order 0.6 eV) between high temperature and low temperature states when we fully relax the coordinates (relative to experimental ones). Futhermore we demonstrate that the charge transfer picture based upon formal valence arguments succeeds qualitatively while failing quantitatively due to strong covalency between the Co 3$d$ orbitals and ligand $p$ orbitals. With the VCI approach, we argue that the high temperature, high spin phase is strongly mixed valent, with about 30 % admixture of Co(III) into the predominantly Co(II) ground state. We confirm this mixed valence through a fit to the XANES spectra. Moreover, the strong electron correlations of the mixed valent phase provide an energy lowering of about 0.2-0.3 eV of the high temperature phase relative to the low temperature one. Finally, we use the domain model to account for the extraordinarily large entropy and enthalpy values associated with the transition.

description: In order to better understand the development level of eco-efficiency in Southeast Guizhou's experimental area of eco-civilization construction, we conduct dynamic comparison research of its eco-efficiency and the national eco-efficiency, using single ratio method based on the ecological footprint model, to grasp the gap between its eco-efficiency and the national eco-efficiency, so that we can take appropriate countermeasures to improve eco-efficiency. The results show that in the period 1978-2010, the eco-efficiency in Southeast Guizhou's experimental area of eco-civilization construction was always lower than the national eco-efficiency; the long-time average annual value of its eco-efficiency was less than one half of that of the national eco-efficiency, with the absolute gap of 1630.095 yuan/hm2, and the gap tended to widen year by year in the period 1978-2002 (the gap increased from 276.551 yuan/hm2 in 1978 to peak of 3227.713 yuan/hm2 in 2002, with an average annual increase of 118.047 yuan/hm2, and especially after 1992, the gap was particularly evident, with an average annual increase of 194.771 yuan/hm2), but from 2003, the gap between the two tended to decrease. Based on the prediction results of grey system, in the period 2011-2025, the gap between the eco-efficiency in Southeast Guizhou's experimental area of eco-civilization construction and the national eco-efficiency will gradually narrow, and from 2019, the eco-efficiency in Southeast Guizhou's experimental area of eco-civilization construction will be more than the national eco-efficiency.

Year: 2025

description: Abstract

This study examines the socio-economic impact of El Niño-induced floods on small-scale farmers in the northern part of Kismaayo District, Lower Jubba, Somalia. The research aims to assess the causes of floods, identify affected communities, and explore mitigation strategies employed by both farmers and authorities. Utilizing an explanatory research design, the study collected data from a sample of 80 respondents, including farmers, residents, and merchants, selected using Slovin’s formula. The findings reveal that 52% of respondents believe the lack of infrastructure such as dams and reservoirs exacerbates the impact of floods, while 33.3% highlight the challenges posed by destroyed roads and bridges, limiting transportation and market access. The study concludes that flooding leads to extensive damage to crops, livestock losses, property destruction, and economic isolation, severely impacting agricultural productivity and livelihoods. Recommendations include the construction of flood control infrastructure, early warning systems, and farmer education on riverbank protection. Implementing these measures will enhance resilience and mitigate the recurring socio-economic consequences of flooding in the region.

description: Acute toxicity of phoxim, acephate, isofenphos-methyl and isocarbophos on male SD rats of clean grade was carried out by gastric lavage method at room temperature of 18℃. These rats are 4 to 5 months old with body weight of 180 to 220 kg. The results indicate that the orders of the toxicity of these four pesticides on SD rats are isofenphos-methyl, isocarbophos, acephate, phoxim. We found that the median lethal concentration of phoxim in 24 h, 48 h, 72 h and 96 h is 3.892g/kg, 3.051 g/kg, 2.618 g/kg and 2.458g/kg respectively; the median lethal concentration of isofenphos-methyl in 24 h, 48 h, 72 h and 96 h is 0.015g/kg, 0.013g/kg, 0.012g/kg and 0.011 g/kg respectively; the median lethal concentration of isocarbophos in 24 h, 48 h, 72 h and 96 h is 0.049 g/kg, 0.046 g/kg, 0.043 g/kg, 0.041 g/kg respectively; and the median lethal concentration of acephate in 24 h, 48 h, 72 h and 96 h is 0.137 g/kg,0.113 g/kg, 0.100 g/kg,0.085 g/kg respectively. Finally, we evaluated the characteristics of toxicity effect and safe concentration of these pesticides to SD rats.

description: We have investigated the conductance of long quantum wires formed in GaAs/AlGaAs heterostructures. Using realistic fluctuation potentials from donor layers we have simulated numerically the conductance of four different kinds of wires. While ideal wires show perfect quantization, potential fluctuations from random donors may give rise to strong conductance oscillations and degradation of the quantization plateaux. Statistically there is always the possibility of having large fluctuations in a sample that may effectively act as a microconstriction. We therefore introduce microconstrictions in the wires by occasional clustering of donors. These microconstrictions are found to restore the quantized plateaux. A similar effect is found for accidental lithographic inaccuracies.

Recent changes in ocean tracers and their implications for ocean circulation
Creators: name: Lester, Joanna Gorham
Publisher: name: Imperial College London
Year: 2020

description: The oceans play a critical role in the climate system, so it is important to understand how ocean circulation is changing with time in order to evaluate the ongoing uptake of anthropogenic heat and carbon from the atmosphere. Ocean tracers can provide valuable insights into such large- scale ocean circulation changes. In this study, I review a new decade of ocean radiocarbon (∆14C) and chlorofluorocarbon (CFC) observations, and describe their recent changes in the context of the last three decades. I compare the observations to a selection of seven ocean models, to evaluate model biases and potentially detect changes in ocean circulation. I also investigate whether the observed changes can be attributed to external forcing, or internal variability. The most recent decade of observations show that average surface ocean ∆14C and CFCs are decreasing, corresponding to their decrease in the atmosphere. Tracers accumulated in the shallow ocean continue to disperse into deeper waters. By comparing the observed tracer changes to modelled tracer changes, I identify regions of enhanced and reduced tracer uptake which could be due to ocean circulation changes, including the Northwest Pacific, the Southern Ocean, the subtropical gyres, the North Atlantic Deep Water and Antarctic Bottom Water. I investigate changes in Southern Ocean circulation in a modelled large ensemble using CFCs, the idealised model tracer Ideal Age (IAGE) and observed changes in CFCs from 1991 to 2005. The ensemble mean change in IAGE is small, suggesting that there has been very little externally forced change in Southern Ocean circulation over this period, in contrast to strong internal variability. My analysis implies that real-world observations of changes in CFCs may not be a robust way to characterize externally driven changes in Southern Ocean circulation because of the large internal variability in CFCs exhibited by the individual ensemble members.

description: DNS is a vital component for almost every networked application. Originally it was designed as an unencrypted protocol, making user security a concern. DNS-over-HTTPS (DoH) is the latest proposal to make name resolution more secure. In this paper we study the current DNS-over-HTTPS ecosystem, especially the cost of the additional security. We start by surveying the current DoH landscape by assessing standard compliance and supported features of public DoH servers. We then compare different transports for secure DNS, to highlight the improvements DoH makes over its predecessor, DNS-over-TLS (DoT). These improvements explain in part the significantly larger take-up of DoH in comparison to DoT. Finally, we quantify the overhead incurred by the additional layers of the DoH transport and their impact on web page load times. We find that these overheads only have limited impact on page load times, suggesting that it is possible to obtain the improved security of DoH with only marginal performance impact.

description: We study the behavior of Heisenberg, antiferromagnetic, integer-spin chains in the presence of a magnetic field exceeding the attendant spin gap. For temperatures much smaller than the gap, the spin chains exhibit Luttinger liquid behavior. We compute exactly both the corresponding Luttinger parameter and the Fermi velocity as a function of magnetic field. This enables the computation of a number of correlators from which we derive the spin conductance, the expected form of the dynamic structure factor relevant to inelastic neutron scattering experiments, and NMR relaxation rates. We also comment upon the robustness of the magnetically induced gapless phase both to finite temperature and finite couplings between neighbouring chains.
description: 32 pages, 8 figures; published version includes additions discussing the robustness of the magnetically induced gapless phase to ordering between chains as well as the relationship between the spin-1 chains and spin-1/2 ladders in the presence of a magnetic field

description: This paper presents a recursive system identification method for multi-degree-of-freedom (MDoF) structures with tuned mass dampers (TMDs) considering abrupt stiffness changes in case of sudden events, such as earthquakes. Due to supplementary non-classical damping of the TMDs, the system identification of MDoF+TMD systems disposes a challenge, in particular, in case of sudden events. This identification methods may be helpful for structural health monitoring of MDoF structures controlled by TMDs. A new adaptation formulation of the unscented Kalman filter allows the identification method to track abrupt stiffness changes. The paper, firstly, describes the theoretical background of the proposed system identification method and afterwards presents three parametric studies regarding the performance of the method. The first study shows the augmented state identification by the presented system identification method applied on a MDoF+TMD system. In this study, the abrupt stiffness changes of the system are successfully detected and localized under earthquake, impulse and white noise excitations. The second study investigates the effects of the state covariance and its relevance for the system identification of MDoF+TMD systems. The results of this study show the necessity of an adaptive definition of the state covariance as applied in the proposed method. The third study investigates the effects of modeling on the performance of the identification method. Mathematical models with discretization of different orders of convergence and system noise levels are studied. The results show that, in particular, MDoF+TMD systems require higher order mathematical models for an accurate identification of abrupt changes.

description: The information theoretic security promised by quantum key distribution (QKD) holds as long as the assumptions in the theoretical model match the parameters in the physical implementation. The superlinear behaviour of sensitive single-photon detectors represents one such mismatch and can pave the way to powerful attacks hindering the security of QKD systems, a prominent example being the after-gate attack. A longstanding tenet is that trapped carriers causing delayed detection can help mitigate this attack, but despite intensive scrutiny, it remains largely unproven. Here we approach this problem from a physical perspective and find new evidence to support a detector's secure response. We experimentally investigate two different carrier trapping mechanisms causing delayed detection in fast-gated semiconductor avalanche photodiodes, one arising from the multiplication layer, the other from the heterojunction interface between absorption and charge layers. The release of trapped carriers increases the quantum bit error rate measured under the after-gate attack above the typical QKD security threshold, thus favouring the detector's inherent security. This represents a significant step to avert quantum hacking of QKD systems.

description: We analyze the onset of classical field configurations after a phase transition. Firstly, we motivate the problem by means of a toy model in quantum mechanics. Subsequently, we consider a scalar field theory in which the system-field interacts with its environment, represented both by further scalar fields and by its own short-wavelength modes. We show that, for very rapid quenches, the order parameter can be treated classically by the time that it has achieved its ground state values (spinodal time).

description: The Perelomov coherent states of SU(1,1) are labeled by elements of the quotient of SU(1,1) by the compact subgroup. Taking advantage of the fact that this quotient is isomorphic to the affine group of the real line, we are able to parameterize the coherent states by elements of that group or equivalently by points in the half-plane. Such a formulation permits to find new properties of the SU(1,1) coherent states and to relate them to affine wavelets.

description: We study experimentally the particle velocity fluctuations in an electrostatically driven dilute granular gas. The experimentally obtained velocity distribution functions have strong deviations from Maxwellian form in a wide range of parameters. We have found that the tails of the distribution functions are consistent with a stretched exponential law with typical exponents of the order 3/2. Molecular dynamic simulations shows qualitative agreement with experimental data. Our results suggest that this non-Gaussian behavior is typical for most inelastic gases with both short and long range interactions.

description: The nanometer-scale gap inhomogeneity revealed by recent STM images of BSCCO surface suggests that the ``gap coherence length'' is of that order. Thus a robust pairing gap can develop despite the poorly screened Coulomb interaction. This can be taken as an evidence that the pairing in high $T_c$ materials occurs primarily in the neutral (spin) sector. We provide theoretical support for this point of view.

description: Critical size bone defects resulting from trauma or disease are challenging to treat due to the size and shape of the defect. Autologous tissue remains the gold standard due to the superior healing potential but harvesting material is challenging due to donor site complications. We have designed a synthetic scaffold system based on emulsion-templating to create porous scaffolds for bone grafting to address these limitations. These polymerized high internal phase emulsions (polyHIPEs) are biodegradable, maintain strong mechanical properties, and can be applied as injectable bone grafts or 3D printed for improved integration at the defect site. The objective of this work was to increase the regenerative capabilities of polyHIPEs by improving the scaffold structure and biocompatibility to facilitate cell-material interactions. First, a series of novel experimental protocols were developed that advanced fabrication and characterization of polyHIPE grafts. Next, compositional and processing variables of HIPE fabrication were tuned to increase polyHIPE pore size for enabling cell infiltration and vascularization. Studies demonstrated tuning macromer viscosity enabled fabrication of scaffolds with target pore sizes > 100 μm. To supplant the use of organic solvents to control macromer viscosity, a biocompatible, reactive diluent was identified for injectable applications of these materials. Finally, this target composition was used to fabricate emulsions stabilized with hydroxyapatite nanoparticles (nHA) to eliminate use of surfactants and improve scaffold biocompatibility. This strategy enabled in situ surface modification of the pore surface facilitating presentation of bioactive components for directing cell behaviors. nHA-stabilized foams maintained superior mechanical properties, improved biocompatibility, and target pore sizes as compared to the traditional surfactant-stabilized foams. In summary, tuning compositional and fabrication parameters allowed for optimizing structural and biological properties of polyHIPE scaffolds, improving their potential to serve as bone replacements. In parallel, development of novel fabrication and characterization protocols supported current progress. Together, this body of work establishes the fundamental knowledge for various platforms that can be utilized to achieve critical design requirements for future polyHIPEs in tissue engineering and other applications.

description: In automated driving systems, monitoring and self-assessment of tracking algorithms is essential. This is especially necessary to meet today’s safety and robustness challenges in an automated system. We propose a hybrid approach to develop a self-monitoring module for tracking algorithms. It makes use of well-known statistical hypothesis testing techniques. The results of which are fed into a subjective logic-based reasoning framework to produce robust and reliable self-assessment scores. Hence, we investigate the potential of combining these two approaches for monitoring and self-assessment systems and show the significance of this approach in experimental results.

description: Introduction: We report on the results of the German early access program (EAP) with the third-generation ALK- and ROS1-inhibitor lorlatinib. Patients and Methods: Patients with documented treatment failure of all approved ALK/ROS1-specific therapies or with resistance mutations not covered by approved inhibitors or leptomeningeal carcinomatosis were enrolled and analyzed. Results: In total, 52 patients were included [median age 57 years (range 32-81), 54% female, 62% never smokers, 98% adenocarcinoma]; 71% and 29% were ALK- and ROS1-positive, respectively. G1202R and G2032R resistance mutations prior to treatment with lorlatinib were observed in 10 of 26 evaluable patients (39%), 11 of 39 patients showed TP53 mutations (28%). Thirty-six patients (69%) had active brain metastases (BM) and nine (17%) leptomeningeal carcinomatosis when entering the EAP. Median number of prior specific TKIs was 3 (range 1-4). Median duration of treatment, progression-free survival (PFS), response rate and time to treatment failure were 10.4 months, 8.0 months, 54% and 13.0 months. Calculated 12-, 18- and 24-months survival rates were 65, 54 and 47%, overall survival since primary diagnosis (OS2) reached 79.6 months. TP53 mutations were associated with a substantially reduced PFS (3.7 versus 10.8 month, HR 3.3, p = 0.003) and were also identified as a strong prognostic biomarker (HR for OS2 3.0 p = 0.02). Neither prior treatments with second-generation TKIs nor BM had a significant influence on PFS and OS. Conclusions: Our data from real-life practice demonstrate the efficacy of lorlatinib in mostly heavily pretreated patients, providing a clinically meaningful option for patients with resistance mutations not covered by other targeted therapies and those with BM or leptomeningeal carcinomatosis.

description: President Trump has created turmoil in the transatlantic relationship. Biden has taken a conciliatory tone towards allies and promised to return the US to multilateral cooperation as president. But the transatlantic relationship will never return to its heyday. Three long-term trends will shape the future of US foreign policy and the transatlantic relationship: the global shift in the distribution of power, and especially what the US-China rivalry means for Europe; the US’ ambivalence towards multilateralism and why it will likely endure; and changing domestic coalitions within the US that might be a harbinger of a foreign policy revolution.

description: We have studied the magnetotransport properties of a high mobility two-dimensional hole gas (2DHG) system in a 10nm GaAs quantum well (QW) with densities in range of 0.7-1.6*10^10 cm^-2 on the metallic side of the zero-field 'metal-insulator transition' (MIT). In a parallel field well above B_c that suppresses the metallic conductivity, the 2DHG exhibits a conductivity g(T)~0.3(e^2/h)lnT reminiscent of weak localization. The experiments are consistent with the coexistence of two phases in our system: a metallic phase and a weakly insulating Fermi liquid phase having a percolation threshold close to B_c.

description: Using numerical techniques, the diagonal and off-diagonal superconducting one-electron Green's functions are calculated for a two-dimensional (2D) t-J model on a periodic 32-site cluster at low doping. From these Green's functions, the momentum and frequency dependence of the pairing gap $Δ({\bf k}, ω)$ are extracted. It has $d_{x^2-y^2}$ symmetry and exhibits $ω$-dependent structure which depend upon J/t. We find that the pairing gap persists down to small J/t values. The frequency- and momentum-dependent renormalized energy and renormalization factor are also calculated.

description: Based on the fact that some important theories like string and M-theories predict spacetime with higher dimensions, so, in this paper, we aim to construct a theory of quintic quasitopological gravity in higher dimensions ($n\geq5$). This $(n+1)$-dimensional quintic quasitopological gravity can also lead to the most second-order linearized field equations in the spherically symmetric spacetimes. These equations can not be solved exactly and so, we obtain a new class of $(n+1)$-dimensional static solutions with numeric methods. For large values of mass parameter $m$, these solutions yield to black holes with two horizons in AdS and flat spacetimes. For dS solutions, there are two values, $m_{\rm ext}$ and $m_{\rm cri}$, which yield to a black hole with three horizons for $m_{\rm ext}

description: In SDN stateful data planes, switches can execute algorithms to process traffic based on local states. This approach permits to offload decisions from the controller to the switches, thus to reduce the latency to react to network events. We consider distributed network applications that process traffic at each switch based on local replicas of network-wide states. Replicating a state across multiple switches poses many challenges, because the number of state replicas and their placement affects both the data traffic and the synchronization traffic among the replicas. In our work, we formulate the optimal placement problem for replicated states, taking into account the data traffic routing, to ensure that the network applications affect the proper traffic flows, and the synchronization traffic between replicas, to ensure state coherence. Due to the high complexity required to find the optimal solution, we propose an approximated algorithm able to scale to large network instances. We show numerically that this algorithm, despite its simplicity, approximates quite well the optimal solution. We also show the beneficial effects of replicating the states with respect to the single-replica scenario, so far considered in the literature. Finally, we provide an asymptotic analysis to find the optimal number of replicas.

description: We study the single particle density of states (DOS) across the superconducting transition (Tc = 31 K) in single-crystal Ba0.67K0.33BiO3 using ultrahigh resolution angle-integrated photoemission spectroscopy. The superconducting gap opens with a pile-up in the DOS, Delta(5.3 K) = 5.2 meV and 2Delta(0)/kBTc = 3.9. In addition, we observe a pseudogap below and above Tc, occurring as a suppression in intensity over an energy scale up to the breathing mode phonon(~ 70 meV). The results indicate electron-phonon coupling induces a pseudogap in Ba0.67K0.33BiO3.

description: Multi-agent coordination is prevalent in many real-world applications. However, such coordination is challenging due to its combinatorial nature. An important observation in this regard is that agents in the real world often only directly affect a limited set of neighbouring agents. Leveraging such loose couplings among agents is key to making coordination in multi-agent systems feasible. In this work, we focus on learning to coordinate. Specifically, we consider the multi-agent multi-armed bandit framework, in which fully cooperative loosely-coupled agents must learn to coordinate their decisions to optimize a common objective. We propose multi-agent Thompson sampling (MATS), a new Bayesian exploration-exploitation algorithm that leverages loose couplings. We provide a regret bound that is sublinear in time and low-order polynomial in the highest number of actions of a single agent for sparse coordination graphs. Additionally, we empirically show that MATS outperforms the state-of-the-art algorithm, MAUCE, on two synthetic benchmarks, and a novel benchmark with Poisson distributions. An example of a loosely-coupled multi-agent system is a wind farm. Coordination within the wind farm is necessary to maximize power production. As upstream wind turbines only affect nearby downstream turbines, we can use MATS to efficiently learn the optimal control mechanism for the farm. To demonstrate the benefits of our method toward applications we apply MATS to a realistic wind farm control task. In this task, wind turbines must coordinate their alignments with respect to the incoming wind vector in order to optimize power production. Our results show that MATS improves significantly upon state-of-the-art coordination methods in terms of performance, demonstrating the value of using MATS in practical applications with sparse neighbourhood structures.
