Abstract:

High-resolution, high-energy, X-ray diffraction results are presented for the study of weak charge ordering phenomenon. By utilizing X-rays in the 100 keV region the dramatic increase in the penetration depth allows for both bulk-sensitive and high-resolution measurements to be made. The strontium doped La 2 NiO 4 system is a prototypical system in the understanding of strong electron-phonon coupling, and the resultant effects on material properties. At doping levels of 1/3 and 1/2 commensurate charge modulations are observed indicating real-space charge stripes. We have measured the correlati

Abstract:

The quasi-2D nickelate La4Ni3O8 (La-438), consisting of trilayer networks of square planar Ni ions, is a member of the so-called T′ family, which is derived from the Ruddlesden–Popper (R-P) parent compound La4Ni3O10−x by removing two oxygen atoms and rearranging the rock salt layers to fluorite-type layers. Although previous studies on polycrystalline samples have identified a 105-K phase transition with a pronounced electronic and magnetic response but weak lattice character, no consensus on the origin of this transition has been reached. Here, we show using synchrotron X-ray diffraction on h

Magnonic bandgap frequency shifts depend upon the external magnetic field and this phenomenon is utilized for magnetic field sensing.

Abstract:

Time series of the Gravity Recovery and Climate Experiment (GRACE) satellite mission have been successfully used to reveal changes in terrestrial water storage (TWS) in many parts of the world. This has been hindered in the interior of the Tibetan Plateau since the derived TWS changes there are very sensitive to the selections of different available GRACE solutions, and filters to remove north-south-oriented (N-S) stripe features in the observations. This has resulted in controversial distributions of the TWS changes in previous studies. In this paper, we produce aggregated hydrology signals (

The gap genes play a key role in establishing pair-rule and homeotic stripes of gene expression in the Drosophila embryo. There is mounting evidence that overlapping gradients of gap gene expression are crucial for this process. Here we present evidence that the segmentation gene giant is a bona fide gap gene that is likely to act in concert with hunchback, Kruppel and knirps to initiate stripes of gene expression. We show that Kruppel and giant are expressed in complementary, non-overlapping sets of cells in the early embryo. These complementary patterns depend on mutually repressive interact

In contrast, when the model is with strong Allee effect, this may lead to the phenomenon of bistability; that is to say, there is a separatrix curve that separates the behavior of trajectories of the sys

Abstract:

In many eukaryotic cells going through M-phase, a bipolar spindle is formed by microtubules nucleated from centrosomes. These microtubules, in addition to being "captured" by kinetochores, may be stabilized by chromatin in two different ways: short-range stabilization effects may affect microtubules in close contact with the chromatin, while long-range stabilization effects may "guide" microtubule growth towards the chromatin (e.g., by introducing a diffusive gradient of an enzymatic activity that affects microtubule assembly). Here, we use both meiotic and mitotic extracts from Xenopus laevis

Abstract:

Relict landforms provide a wealth of information on the evolution of the modern landscape and climate change in the past. To improve understanding of the origin and development of these landforms we need better spatial measurements across a variety of scales. This can be challenging using conventional surveying techniques due to difficulties in landform recognition on the ground (e.g. weak visual/topographic expression) and spatially variable areas of interest. Here we explore the appropriateness of existing remote sensing datasets (aerial LiDAR and aerial photography) and newly acquired unman

Abstract:

The gobiid genus Koumansetta Whitley, placed in synonymy by some authors with the similar genus Amblygobius Bleeker, is redescribed and its validity based on an integrated morphological and molecular assessment is confirmed. The following characters have been found that distinguish Koumansetta from any of 15 recognized valid species of Amblygobius: oculoscapular transverse rows trp and tra long, extending dorsally well above level of rows x1 and x2; snout pointed, prominent, longer than eye diameter, with gently sloping dorsal profile, overhanging mouth; mouth subterminal; the upper limb of fi

With the rapid growth of China’s digital culture industry and the expanding market potential, the industry's development has become an essential avenue for marketizing the industrial economy. However, as China's digital culture industry strives to strengthen its core and make strides onto the international stage, it grapples with developmental challenges such as a weak theoretical foundation, a lack of content innovation, inadequate legal and regulatory oversight, and an imbalanced industrial structure. In light of these issues, this study conducts an analysis of the aforementioned challenges

Abstract:

Background: Stripe wear is a well-known phenomenon that might be caused by rim impingement, edge loading, metal particle entrapment, micro-separation, and transient subluxation. Stripe wear is felt to represent metal transfer and has been associated with squeaking in ceramic-on-ceramic bearings. In our paper, we report the presence of stripe wear on a retrieved modular ceramic femoral head from a patient with ceramic-on-polyethylene-bearing total hip arthroplasty. Method: We report a case of a 57-year-old male who originally had metal-on-metal (MOM) THA and underwent debridement and exchange o

Abstract:

Bionic strips were designed and processed on the piston of BW-160 slime pump to improve its friction performance, decrease wear mass losses, and prolong service life. Nine stripped pistons were processed and manifested by different strip depths and included angles between stripes and piston surface. A workbench of slime pump piston was created to test the frictional force, oil film width, and wear mass losses. Test results demonstrated that the stripped structure can significantly decrease the frictional force on the piston. Optimal strip depth, included angle, and resistance reduction rates f

Abstract:

This study explores the mechanisms underlying the enhanced anti-wear and thermal fatigue performance of laser-treated bionic brake drums, aiming to extend their service life and improve design quality. Bionic brake drums treated with laser patterns—point, stripe, and grid—were tested with semi-metallic, non-asbestos organic (NAO), and ceramic brake pads. A mechanical model was developed to analyze wear performance, and bench tests were conducted to assess wear patterns. Thermal fatigue tests examined the impact of thermal cycling on the treated drums’ wear behavior. The results reveal that las

Abstract:

We have recently shown that a hybrid magnetic thin film with orthogonal anisotropies presenting weak stripe domains can achieve a high degree of controllability of its ferromagnetic resonance. This work explores the origin of the reconfigurability through micromagnetic simulations. The static domain structures which control the thin film resonance can be found under a deterministic applied field protocol. In contrast to similar systems reported, our effect can be obtained under low magnetic fields. We have also found through simulations that the spin wave propagation in the hybrid is nonrecipr

Abstract:

The overhead conductor system (OCS) could be one of the most economical and feasible engineering solutions to the problem of how to transmit electrical energy to intercity trains (typically at 25 kV AC) or urban/suburban trains (typically at 1.5 kV DC) along open or tunnel routes. However, the consumption of contact wire and collector strips due to wear and tear could impose a severe cost on the railway operator should the interaction between the wear couple formed by the OCS and the pantograph be poor. Following the completion of several OCS improvement projects, this paper examines the facto
