Criterion for remote clock synchronization with Heisenberg-scaling accuracy

We propose a quantum method to judge whether two spatially separated clocks have been synchronized within a specific accuracy sigma. If the measurement result of the experiment is clearly a nonzero value, the time difference between two clocks is smaller than sigma; otherwise, the difference is beyond sigma. Upon sharing the 2N-qubit bipartite maximally entangled state in this scheme, the accuracy of judgment can be enhanced to sigma similar to pi/[omega(N + 1)]. This criterion is consistent with Heisenberg scaling, which can be considered as the beating standard quantum limit; moreover, the unbiased estimation condition is not necessary. In particular, we demonstrate that this scheme is still feasible when suffering the loss of qubits.
Benefits of Moringa Oleifera Leaves Meal (Molm) As a Natural Feed Supplement of Broiler Chicks Reared Under Heat Stress Conditions

Benefits of Moringa Oleifera Leaves Meal (Molm) As a Natural Feed Supplement of Broiler Chicks Reared Under Heat Stress Conditions. Abstract A growth experiment was conducted to study productive performance, carcass characteristics and some blood pa rameters of broiler chicks fed corn-soybean meal diets supplemented with Moringa Oleifera Leaves Meals (MOLM) under heat stress condition. Three hundred a week-old chicks were randomly assigned to five treatments designated as T 1 , T 2 , T 3 , T 4 and T 5 supplemented with MOLM (0, 5, 7.5, 10 and 12.5%), respectively. The results did not show that body weight gain, feed intake and final weight increased with increased inclusion levels of MOLM, so also was the feed conversion ratio. The cumulative feed conversion ratio was better in T 2 . The levels of MOLM had no significant (P>0.05) effect on carcass relative weight, Haemoglobin (HB), White Blood Cells (WBC), albumin and total plasma protein in creased with increasing levels of MOLM. Mortality rates de creased with increasing levels of MOLM. The best result in most of the parameters however, was obtained in T 2 (5%) inclusion level. It could be concluded that addition of Mo ringa oleifera leaves improved broiler performance, blood parameters and enhanced the ability to resist heat stress conditions of broilers fed corn-soybean meal diet.
The effect of elemental diffusion on the application of olivine-composition-based magmatic thermometry, oxybarometry, and hygrometry: A case study of olivine phenocrysts from the Jiagedaqi basalts, northeast China

Abstract Olivine compositions are widely used to constrain magmatic thermodynamic conditions such as magmatic temperature, oxygen fugacity, and H2O content. However, elemental diffusion may change the initial compositions and lead to large uncertainty on the estimation of these thermodynamic conditions. In this study, we conducted LA-ICP-MS elemental mapping and EPMA analysis of olivine phenocrysts and olivine-hosted spinel from the Jiagedaqi (JGD) alkaline basalts in northeast China to evaluate the influence of elemental difusion on olivine-composition-based geothermometry, oxybarometry, and hygrometry. The JGD olivines show normal Fo [Mg/(Mg + Fe) × 100 in moles] zoning, with cores having Fo of 77–87 and rims having Fo of 67–73. The constant P contents from core to rim indicate that these compositional zonings were caused mainly by difusion. Because Al is a slow-diffusing element and its content is relatively constant from core to rim, the temperature calculated by the Al-in-olivine thermometer is not influenced by elemental difusion and preserves the JGD olivine crystallization temperature up to 1150 °C. The temperatures calculated using the Sc/Y-in-olivine thermometer, the oxygen fugacity calculated using the olivine–spinel oxybarometer, and the H2O content calculated on the basis of Ca partitioning between olivine and melt are strongly influenced by the diffusion of Fo, Sc/Y, and Ca. However, the compositional plateaus in olivine cores, which were not influenced by elemental diffusion, preserve the magmatic temperature (1150 °C), oxygen fugacity (QFM+1.4), and H2O content (4 wt%) that applied during the formation of the JGD olivines. Together, these findings suggest that the mantle source of the JGD basalts was metasomatized by fluids released from the subducted slab. This study highlights that elemental difusion in olivine phenocrysts can strongly afect the application of olivine-composition-based geothermometers, oxybarometers, and hygrometers. However, primitive olivine cores that have not been influenced by difusion preserve the initial magmatic thermodynamic conditions.
X-RAY OBSERVATIONS OF THE SUPERNOVA REMNANT CTB 87 (G74.9+1.2): AN EVOLVED PULSAR WIND NEBULA

Pulsar wind nebulae (PWNe) studies with the Chandra X-Ray Observatory have opened a new window to address the physics of pulsar winds, zoom on their interaction with their hosting supernova remnant (SNR) and interstellar medium, and identify their powering engines. We here present a new 70 ks, plus an archived 18 ks, Chandra ACIS observation of the SNR CTB 87 (G74.9+1.2), classified as a PWN with unusual radio properties and poorly studied in X-rays. We find that the peak of the X-ray emission is clearly offset from the peak of the radio emission by ∼100″ and located at the southeastern edge of the radio nebula. We detect a point source—the putative pulsar—at the peak of the X-ray emission and study its spectrum separately from the PWN. This new point source, CXOU J201609.2+371110, is surrounded by a compact nebula displaying a torus-like structure and possibly a jet. A more extended diffuse nebula is offset from the radio nebula, extending from the point source to the northwest for ∼250″. The spectra of the point source, compact nebula, and extended diffuse nebula are all well described by a power-law model with a photon index of 1.1 (0.7–1.6), 1.2 (0.9–1.4), and 1.7 (1.5–1.8), respectively, for a column density NH = 1.38 (1.21–1.57) × 1022 cm−2 (90% confidence). The total X-ray luminosity of the source is ∼1.6 × 1034 erg s−1 at an assumed distance of 6.1 kpc, with ∼2% and 6% contribution from the point source and compact nebula, respectively. The observed properties suggest that CTB 87 is an evolved (∼5–28 kyr) PWN, with the extended radio emission likely a “relic” PWN, as in Vela-X and G327.1−1.1. To date, however, there is no evidence for thermal X-ray emission from this SNR, and the SNR shell is still missing, suggesting expansion into a low-density medium ( cm−3), likely caused by a stellar wind bubble blown by the progenitor star.
Clinical and Radiological Evaluation of Tie-in Osteosynthesis with Intramedullary Threaded Pin in Diaphyseal Humeral, Tibial, and Femoral Fractures in Dogs Köpeklerde Diyafizer Humerus, Tibia ve Femur Kırıklarında İntramedüller Yivli Pin İle Tie-in Osteosentezin Klinik ve Radyolojik Olarak Değerlend

: This study aimed to perform the “tie-in” osteosynthesis technique using an intramedullary threaded pin for the treatment of diaphyseal humeral, tibial, and femoral fractures in dogs, thus minimizing rotational movements and strengthening stabilization, particularly in distal diaphyseal fractures. The study included 16 fracture cases involving 14 dogs of various breeds and sexes, aged 3-12 months, and diagnosed with diaphyseal humeral, tibial, and femoral fractures. Depending on the size of the case, Ø2-4 mm-threaded Steinmann pins were preferred for use in intramedullary pinning and Ø2-4 mm-threadless Steinmann pins were placed transversal for fixation. Acrylic, rod, or fiberglass plaster was used to attach the inserted pins. Fusion was formed in all except two cases. Consequently, the animals could use their relevant extremities without issues during the first 3 days following the operation, but from day 3 until day 15, the animals were reluctant to use their relevant extremities. After day 15, the animals could use their extremities without difficulty. The external fixator components used in fracture fixation were entirely removed after 5-7 (mean 6) weeks. In the functional evaluation, the conditions were very good in nine cases, good in four, moderate in one, and poor in two. The results reveal that the use of threaded pins in intramedullary pinning, the first step of the tie-in method, provides good stabilization in fracture treatment, especially in distal diaphyseal fractures.
Comparative Study ofMultiple High-Signal-Intensity Spots on 3D and 2D Magnetic Resonance Sialography for Patients with Sjögren’s Syndrome

We investigated the sensitivities of 2-dimensional (2D) magnetic resonance sialography (MR-S) and unilateral sagittal and axial 3dimensional (3D) MR-S using a surface coil and their combination in diagnosing patients with Sjögren’s syndrome (SS). We retrospectively analyzed the 3D and 2DMR-S results of 78 patients with SS. We evaluated the sensitivities of multiple high-signalintensity spots and staging onMR sialograms and analyzed the efficient imagingmethods and cross section for diagnosing patients with SS. e sensitivities of MR-S for detecting abnormal findings (i.e., MR-S stage 1 or higher) were as follows: 65 cases (83.3% [95% confidence interval (CI): 73.2–90.8]) for unilateral sagittal 3DMR-S; 62 cases (79.4% [95%CI: 68.8–87.8]) for axial 3DMR-S; 66 cases (84.6% [95% CI: 74.7–91.8]) for combined unilateral sagittal and axial 3DMR-S; and 32 cases (41.0% [95% CI: 30.0–52.7]) for bilateral sagittal 2D MR-S. e ratio of the abnormal finding of MR-S was tested using the two-tailed Fisher’s exact test. Unilateral sagittal, axial, and combined unilateral sagittal and axial 3D MR-S showed significantly higher sensitivity than bilateral sagittal 2D MR-S, respectively (P< 0.001). Most cases upstaged by 3D MR-S were those positive (stage 1 or higher) among the stage 0 cases detected by 2D MR-S. Axial 3D MR-S, compared with 2D MR-S, understaged four cases, which was due to the imaging range of the axial 3DMR-S. We concluded that a single unilateral sagittal 3DMR-S was sufficient and axial 3DMR-S was unnecessary for SS staging. T1and T2-weighted images are essential for investigating the salivary glands in patients with SS. erefore, we also concluded that bilateral sagittal 3D MR-S of the parotid glands in addition to T1and T2-weighted imaging is necessary, sufficient, and most efficient for precise MR imaging examination of the salivary glands, including diagnosing SS.

This project addresses the design of stacked microstrip patch antenna for wireless application. The proposed microstrip stack antenna has the operating frequency at 4GHz. The antenna is designed with FR-4 material as substrate that as the relative permittivity of 4.4 and loss tangent 0.02. The feeding technique used is microstrip feeding. The stacked microstrip antenna overcomes the limitations of normally narrowband microstrip antenna without altering the ground plane, which helps the antenna to achieve a unidirectional radiation pattern along with large bandwidth. The proposed antenna is suitable for various wireless applications. The proposed antenna is designed and simulated using HFSS (High Frequency Structural Simulator) software.
Control in Montague Grammar

The problem of interpreting "'missing" noun phrases in predicate structures has been a central concern of transformational theory since its inception. Recently, a number of linguists, under various versions of the "'extended standard theory", have dealt with this problem of "'control" (see Brame (1976), Bresnan (1972; 1978), Chomsky (1957; 1965; 1973; 1976), Chomsky and Lasnik (1977), Faraci (1974), Jackendoff (1972), Solan (1978), Wilkins (1977), Williams (1977)). Many of these writers share the assumption that control is to be determined by rules operating on intermediate structures of a certain sort that contain various abstract elements such as traces, empty nodes, and complementizers. Not so well known are treatments within a different tradition which has taken its inspiration from Richard Montague (see especially papers 6, 7, 8 in Montague (1974)). Common to all these treatments is the requirement that the fragments contain both an explicit set of syntactic rules and an explicit model-theoretical interpretation. We may view the results as systems which build "bottom-to-top" a syntactic structure and a corresponding representation of "logical form" (a structure in an interpreted intensional logic). The sole abstract elements are an infinite set of indexed pro-forms which underlie pronouns. Partee (1975a,b; 1976b), Thomason (1976), and Dowty (forthcoming) are among those who have addressed the sorts of problems we will be concerned with here. I wish to extend the treatments of these writers to cover some of the knottier problems that have been discussed in the recent transformational iterature. The specific framework I will use draws upon both the transformational and the Montague traditions.1 Montague has often been criticized for his views of syntax. A subsidiary aim of this article is to explore an approach to English syntax that is in the spirit of Montague's practice, especially in PTQ. It seems to me that Montague syntax offers an interesting alternative to transformational syntax of all varieties. Among the assumptions I will make are these: A. A grammar defines sets of structural descriptions. Each is an ordered pair: (a)
Optimal fidelity of teleportation with continuous variables using three tunable parameters in a realistic environment

We introduce three tunable parameters to optimize the fidelity of quantum teleportation with continuous-variable in nonideal scheme. Using the characteristic function formalism, we present the condition that the teleportation fidelity is independent of the amplitude of input coherent states for any entangled resource. Then we investigate the effects of tunable parameters on the fidelity with or without the presence of environment and imperfect measurements, by analytically deriving the expression of fidelity for three different input coherent state distributions. It is shown that, for the linear distribution, the optimization with three tunable parameters is the best one with respect to single- and two-parameter optimization. Our results reveal the usefulness of tunable parameters for improving the fidelity of teleportation and the ability against the decoherence.
AN ORDERED MAGNETIC FIELD IN THE PROTOPLANETARY DISK OF AB Aur REVEALED BY MID-INFRARED POLARIMETRY

Magnetic fields (B-fields) play a key role in the formation and evolution of protoplanetary disks, but their properties are poorly understood due to the lack of observational constraints. Using CanariCam at the 10.4 m Gran Telescopio Canarias, we have mapped out the mid-infrared polarization of the protoplanetary disk around the Herbig Ae star AB Aur. We detect ∼0.44% polarization at 10.3 μm from AB Aur's inner disk (r < 80 au), rising to ∼1.4% at larger radii. Our simulations imply that the mid-infrared polarization of the inner disk arises from dichroic emission of elongated particles aligned in a disk B-field. The field is well ordered on a spatial scale, commensurate with our resolution (∼50 au), and we infer a poloidal shape tilted from the rotational axis of the disk. The disk of AB Aur is optically thick at 10.3 μm, so polarimetry at this wavelength is probing the B-field near the disk surface. Our observations therefore confirm that this layer, favored by some theoretical studies for developing magneto-rotational instability and its resultant viscosity, is indeed very likely to be magnetized. At radii beyond ∼80 au, the mid-infrared polarization results primarily from scattering by dust grains with sizes up to ∼1 μm, a size indicating both grain growth and, probably, turbulent lofting of the particles from the disk mid-plane.
Data-Efficient Characterization of the Global Dynamics of Robot Controllers with Confidence Guarantees

This paper proposes an integration of surrogate modeling and topology to significantly reduce the amount of data required to describe the underlying global dynamics of robot controllers, including closed-box ones. A Gaussian Process (GP), trained with randomized short trajectories over the state-space, acts as a surrogate model for the underlying dynamical system. Then, a combinatorial representation is built and used to describe the dynamics in the form of a directed acyclic graph, known as Morse graph. The Morse graph is able to describe the system's attractors and their corresponding regions of attraction (RoA). Furthermore, a pointwise confidence level of the global dynamics estimation over the entire state space is provided. In contrast to alternatives, the framework does not require estimation of Lyapunov functions, alleviating the need for high prediction accuracy of the GP. The framework is suit-able for data-driven controllers that do not expose an analytical model as long as Lipschitz-continuity is satisfied. The method is compared against established analytical and recent machine learning alternatives for estimating Roas, outperforming them in data efficiency without sacrificing accuracy.

An Rna Sequencing Analysis of Glaucoma Genesis in Mice

Glaucoma is the leading cause of irreversible blindness in people over the age of 60, accounting for 6.6 to 8% of all blindness in 2010, but there is still much to be learned about the genetic origins of the eye disease. With the modern development of Next-Generation Sequencing (NGS) technologies, scientists are starting to learn more about the genetic origins of Glaucoma. This research uses differential expression (DE) and gene ontology (GO) analyses to study the genetic differences between mice with severe Glaucoma and multiple control groups. Optical nerve head (ONH) and retina data samples of genome-wide RNA expression from NCBI (NIH) are used for pairwise comparison experimentation. In addition, principal component analysis (PCA) and dispersion visualization methods are employed to perform quality control tests of the sequenced data. Genes with skewed gene counts are also identified, as they may be marker genes for a particular severity of Glaucoma. The gene ontologies found in this experiment support existing knowledge of Glaucoma genesis, providing confidence that the results were valid. Future researchers can thoroughly study the gene lists generated by the DE and GO analyses to find potential activator or protector genes for Glaucoma in mice to develop drug treatments or gene therapies to slow or stop the progression of the disease. The overall goal is that in the future, such treatments can be made for humans as well to improve the quality of life for human patients with Glaucoma and reduce Glaucoma blindness rates.
O2S: Open-source open shuttle

Currently, commercially available intelligent transport robots that are capable of carrying up to 90kg of load can cost $5,000 or even more. This makes real-world experimentation prohibitively expensive, and limiting the applicability of such systems to everyday home or industrial tasks. Aside from their high cost, the majority of commercially available platforms are either closed-source, platform-speciﬁc, or use diﬃcult-to-customize hardware and ﬁrmware. In this work, we present a low-cost, open-source and modular alternative, referred to herein as "open-source open shuttle ( O 2 S )". O 2 S utilizes oﬀ-the-shelf (OTS) components, additive manufacturing technologies, aluminium proﬁles, and a consumer hoverboard with high-torque brushless direct current (BLDC) motors. O 2 S is fully compatible with the robot operating system (ROS), has a maximum payload of 90kg, and costs less than $1500. Furthermore, O 2 S oﬀers a simple yet robust framework for contextualizing simultaneous localization and mapping (SLAM) algorithms, an essential prerequisite for autonomous robot navigation. The robustness and performance of the O 2 S were validated through real-world and simulation experiments. All the design, construction and software ﬁles are freely available online under the GNU GPL v3 license at https://doi.org/10.17605/OSF.IO/K83X7. A descriptive video of O 2 S can be found at https://osf.io/v8tq2.
Application of Stable Inversion to Flexible Manipulators Modeled by the ANCF

Summary Compared to conventional robots, ﬂexible manipulators oﬀer many advantages, such as faster end-eﬀector velocities and less energy consumption. However, their ﬂexible structure can lead to undesired oscillations. Therefore, the applied control strategy should account for these elasticities. A feedforward controller based on an inverse model of the system is an eﬃcient way to improve the performance. However, unstable internal dynamics arise for many common ﬂexible robots and stable inversion must be applied. In this contribution, an approximation of the original stable inversion approach is proposed. The approximation simpliﬁes the problem setup, since the internal dynamics do not need to be derived explicitly for the deﬁnition of the boundary conditions. From a practical point of view, this makes the method applicable to more complex systems with many unactuated degrees of freedom. Flexible manipulators modeled by the absolute nodal coordinate formulation (ANCF) are considered as an application example.
Guiding the PLMs with Semantic Anchors as Intermediate Supervision: Towards Interpretable Semantic Parsing

The recent prevalence of pretrained language models (PLMs) has dramatically shifted the paradigm of semantic parsing, where the mapping from natural language utterances to structured logical forms is now formulated as a Seq2Seq task. Despite the promising performance, previous PLM-based approaches often suffer from hallucination problems due to their negligence of the structural information contained in the sentence, which essentially constitutes the key semantics of the logical forms. Furthermore, most works treat PLM as a black box in which the generation process of the target logical form is hidden beneath the decoder modules, which greatly hinders the model’s intrinsic interpretability. To address these two issues, we propose to incorporate the current PLMs with a hierarchical decoder network. By taking the ﬁrst-principle structures as the semantic anchors, we propose two novel intermediate supervision tasks, namely Semantic Anchor Extraction and Semantic Anchor Alignment , for training the hierarchical decoders and probing the model intermediate representations in a self-adaptive manner alongside the ﬁne-tuning process. We conduct intensive experiments on several semantic parsing benchmarks and demonstrate that our approach can consistently outperform the baselines. More importantly, by analyzing the intermediate representations of the hierarchical decoders, our approach also makes a huge step toward the intrinsic interpretability of PLMs in the domain of semantic parsing.
