Many network applications, e.g., industrial control, demand Ultra-Low Latency (ULL). However, traditional packet networks can only reduce the end-to-end latencies to order of tens milliseconds. The IEEE 802.1 Time Sensitive Networking (TSN) standard and related research studies have sought provide link layer support for ULL networking, while emerging IETF Deterministic (DetNet) standards seek complementary support. This article provides an up-to-date comprehensive survey TSN DetNet studies....
The IEEE 802.1 time sensitive networking working group has recently standardized the aware shaper (TAS). TAS provides deterministic latency guarantees but requires tight synchronization in all network switches. This paper thoroughly evaluates mean and maximum packet delays losses of for a typical industrial control ring random (sporadic) periodic traffic. We propose evaluate adaptive bandwidth sharing slotted window mechanisms to make traffic fluctuations. further asynchronous (ATS), which...

In two-dimensional van der Waals magnets, the presence of magnetic orders, strong spin–orbit coupling, and asymmetry at interfaces is key ingredient for hosting noncollinear spin textures. Here, we investigate characteristics evolution domain structures in thin Fe3GeTe2 nanolayers as a function temperature, applied field, specimen thickness using advanced electron microscopy. Specifically, holography analyses reveal configurations Bloch-type, zero-field-stabilized bubbles 20-nm-thick...
Fragrance compounds and essential oils are chosen carefully taking advantage of research works in aromatherapy. Considering their volatile nature, the fragrance molecules have to be formed as inclusion with cyclodextrin order retain fragrances for a long time. To prepare aromatherapeutic textiles, β-cyclodextrin is first choice host molecule, because capable forming organic that fit into own cone-shaped hydrophobic cavities. As result inclusion, physicochemical properties changed; example,...
1T-TiSe_{2} is one of the most studied charge density wave (CDW) systems, not only because its peculiar properties related to CDW transition, but also due status as a promising candidate exciton insulator signaled by proposed plasmon softening at vector. Using high-resolution electron energy loss spectroscopy, we report systematic study temperature-dependent behaviors 1T-TiSe_{2}. We unambiguously resolve from phonon modes, revealing existence Landau damping finite momentums, which does...
The coexistence of ferroelectricity and metallicity seems paradoxical, since the itinerant electrons in metals should screen long-range dipole interactions necessary for ordering. recent discovery polar metal LiOsO3 was therefore surprising [as discussed earlier Y. Shi et al., Nat. Mater. 2013, 12, 1024]. It is thought that coordination preferences Li play a key role stabilizing phase, but an investigation from combined viewpoints core-state specificity symmetry has yet to be done. Here, we...

Energy efficiency is a critical problem for wireless sensor networks. In past decades, network coding has been proved as promising technology to reduce the number of transmissions, save energy, and improve throughput, especially suitable that motivates emergence aware routings. However, existing routings have failure decoding problem, because defective conditions. On other hand, usually consider ideal traffic scheduling neglect nodes' energy load which are important Therefore, it not...
Magnetic Weyl semimetal (MWS) is a unique topological state with open surface Fermi arc states and other exotic transport phenomena. However, most reported MWSs show multiple pairs of points complicated surfaces, which increases the difficulty investigation into intrinsic chiral property. In this wor, we successfully synthesized soft magnetic Eu3In2As4 single pair under fields. The Shubnikov de Haas (SdH) oscillation frequency, as well linear hall resistance same carrier density, observed up...
In two-dimensional van der Waals (vdW) magnets, the presence of magnetic orders, strong spin-orbit coupling and asymmetry at interfaces is key ingredient for hosting chiral spin textures. However, experimental evidences magnetism in vdW magnets remain elusive.

This paper proposes a network coding aware QoS (quality of service) routing (NCQR) for wireless sensor network, which exploits technology to improve the network. Network condition with constraint is proposed, provides proof opportunity detection. To facilitate evaluation discovered routes, novel metric, called CQRM (coding metric), presented, jointly considers link quality, node congestion and opportunity. Simulation results demonstrate that NCQR decreases blocking ratio requests...
Network coding–based routing has been widely considered as a promising technology to improve the network throughput of wireless multihop network.

We studied the magnetism in ${\mathrm{NdFe}}_{2}{\mathrm{Ga}}_{8}$ by magnetic susceptibility, specific heat, and resistivity measurements, which show ${\mathrm{Nd}}^{3+}$ ions forming one-dimensional chains along $c$ axis. At zero field, two transitions are found at about 15 11 K. For field vertical to axis, no significant effects on orders found. On other hand, merged together 4 T for parallel axis completely suppressed 7 T. The suppression of order results quantum critical behaviors...
Topological crystalline insulators (TCIs) are insulating electronic states with nontrivial topology protected by symmetries. Recently, theory has proposed new classes of TCIs rotation symmetries [Formula: see text], which have surface anomaly evading the fermion doubling theorem, i.e., n instead 2n Dirac cones on preserving symmetry. Here, we report first realization text] in a binary compound SrPb. Our first-principles calculations reveal two massless fermions combination time-reversal...
In many strongly correlated insulators, antiferromagnetic order competes with exotic and technologically relevant phases, like superconductivity. While control of spin is critical to stabilize different functional states, elucidating the mechanism laser-induced demagnetization in complex oxides remains a challenge. It unknown if optical pulse can quench magnetization nonthermally or it instead only acts as heat source. Here, we use ultrafast, broadband, spectroscopy track responses...
