Backfilling behavior of a mixed aggregate based on construction waste and ultrafine tailings

To study the possibility of utilizing mixed construction waste and ultrafine tailings (CW&UT) as a backfilling aggregate that can be placed underground in a mine, physicochemical evaluation, proportioning strength tests, and pumpability experiments were conducted. It was revealed that mixed CW&UT can be used as a backfilling aggregate due to the complementarities of their ...

A method for defensing against multi-source Sybil attacks in VANET

Sybil attack can counterfeit traffic scenario by sending false messages with multiple identities, which often causes traffic jams and even leads to vehicular accidents in vehicular ad hoc network (VANET). It is very difficult to be defended and detected, especially when it is launched by some conspired attackers using their legitimate identities. In this paper, we propose an event ...

Critical nodes identification in complex systems

performance metrics to B Xin Chen identify critical nodes in complex systems such as smart grid, social networks, information systems, and criminal organizations. For example, to protect an electrical power

Transcriptome analysis of hexaploid hulless oat in response to salinity stress

Background Oat is a cereal crop of global importance used for food, feed, and forage. Understanding salinity stress tolerance mechanisms in plants is an important step towards generating crop varieties that can cope with environmental stresses. To date, little is known about the salt tolerance of oat at the molecular level. To better understand the molecular mechanisms underlying ...

Effects of Defects on the Mechanical Properties of Kinked Silicon Nanowires

Kinked silicon nanowires (KSiNWs) have many special properties that make them attractive for a number of applications. The mechanical properties of KSiNWs play important roles in the performance of sensors. In this work, the effects of defects on the mechanical properties of KSiNWs are studied using molecular dynamics simulations and indirectly validated by experiments. It is found ...

Positive asymptotically almost periodic solutions for hematopoiesis model

By using the fixed point theory and Lyapunov functional, we establish the existence and stability of asymptotically almost periodic solution to hematopoiesis of the form x ′ ( t ) = − a ( t ) x ( t ) + ∑ i = 1 k b i ( t ) 1 + x n ( t − τ i ( t ) ) , t ∈ R . Unlike many previous related results, we do not assume the condition inf t ∈ R a ( t ) > 0 , which is a key assumption in ...

Optical Constants and Band Gap Evolution with Phase Transition in Sub-20-nm-Thick TiO2 Films Prepared by ALD

Titanium dioxide (TiO2) ultrathin films with different thicknesses below 20 nm were grown by atomic layer deposition (ALD) on silicon substrates at 300 °C. Spectroscopic ellipsometry (SE) measurements were operated to investigate the effect of thickness on the optical properties of ultrathin films in the spectra range from 200 to 1000 nm with Forouhi–Bloomer (F-B) dispersion ...

A randomized controlled trial on effects of different hemostatic sponges in posterior spinal fusion surgeries

Background Spinal fusion surgery is associated with significant blood loss, which may result in potential clinical complications, it is necessary to take safe and effective measures to reduce blood loss in surgery. We perform this study to assess the impact of three different hemostatic materials on perioperative blood loss. Methods We performed a Randomized Controlled Trial ...

4DCT and CBCT based PTV margin in Stereotactic Body Radiotherapy(SBRT) of non-small cell lung tumor adhered to chest wall or diaphragm

Background Large tumor motion often leads to larger treatment volumes, especially the lung tumor located in lower lobe and adhered to chest wall or diaphragm. The purpose of this work is to investigate the impacts of planning target volume (PTV) margin on Stereotactic Body Radiotherapy (SBRT) in non-small cell lung cancer (NSCLC). Methods Subjects include 20 patients with the lung ...

\(\bar{B}_{d,s} \rightarrow D^{*}_{d,s} V\) and \(\bar{B}_{d,s}^* \rightarrow D_{d,s} V\) decays in QCD factorization and possible puzzles

Motivated by the rapid development of heavy-flavor experiments, phenomenological studies of nonleptonic \(\bar{B}_{d,s} \rightarrow D^{*}_{d,s} V\) and \(\bar{B}_{d,s}^* \rightarrow D_{d,s} V\) (\(V=\rho \,,K^*\)) decays are performed within the framework of QCD factorization. Relative to the previous work, the QCD corrections to the transverse amplitudes are evaluated at ...

HCV Diversity among Chinese and Burmese IDUs in Dehong, Yunnan, China

HCV transmission is closely associated with drug-trafficking routes in China. Dehong, a prefecture of Yunnan, is the important trade transfer station linking Southeast Asia and China, as well as the drug-trafficking channel linking “Golden triangle” and other regions of China and surrounding countries. In this study, we investigated the HCV genotype diversity among IDUs in Dehong ...

A general thermodynamical description of the event horizon in the FRW universe

The Friedmann equation in the Friedmann–Robertson–Walker (FRW) universe with any spatial curvature is derived from the first law of thermodynamics on the event horizon. The key idea is to redefine a Hawking temperature on the event horizon. Furthermore, we obtain the evolution equations of the universe including the quantum correction and explore the evolution of the universe in ...

The Arginine/Lysine-Rich Element within the DNA-Binding Domain Is Essential for Nuclear Localization and Function of the Intracellular Pathogen Resistance 1

The mouse intracellular pathogen resistance 1 (Ipr1) gene plays important roles in mediating host immunity and previous work showed that it enhances macrophage apoptosis upon mycobacterium infection. However, to date, little is known about the regulation pattern of Ipr1 action. Recent studies have investigated the protein-coding genes and microRNAs regulated by Ipr1 in mouse ...
