The measurement of the energy spectrum cosmic ray helium nuclei from 70 GeV to 80 TeV using 4.5 years data recorded by Dark Matter Particle Explorer (DAMPE) is reported in this work. A hardening observed at an about 1.3 TeV, similar previous observations. In addition, a spectral softening 34 revealed for first time with large statistics and well controlled systematic uncertainties, overall significance 4.3σ. DAMPE measurements both protons suggest particle charge dependent energy, although...
Abstract Unconventional superconductors often feature competing orders, small superfluid density, and nodal electronic pairing. While unusual superconductivity has been proposed in the kagome metals A V 3 Sb 5 , key spectroscopic evidence remained elusive. Here we utilize pressure-tuned ultra-low temperature muon spin spectroscopy to uncover unconventional nature of RbV KV . At ambient pressure, observed time-reversal symmetry breaking charge order below...
Twenty-one species of cyclostome bryozoans are described from the coast Qingdao (South Yellow Sea, China), belonging to 11 genera (Filicrisia, Crisia, Tubulipora, Exidmonea, Idmidronea, Qingdaoella n. gen., Nevianipora, Hemipustulopora, Microeciella, Patinella and Disporella). One genus (Qingdaoella gen.) 10 new, while an additional is reported for first time China. The most similar bryozoan assemblages Chinese cyclostomes here Sea Japan western Pacific.
Recent observations of the light component cosmic-ray spectrum have revealed unexpected features that motivate further and more precise measurements up to highest energies. The Dark Matter Particle Explorer is a satellite-based experiment has been operational since December 2015, continuously collecting data on high-energy cosmic particles with very good statistics, energy resolution, particle identification capabilities. In this work, latest proton+helium in range from 46 GeV 464 TeV are...

Precise direct cosmic-ray (CR) measurements provide an important probe to study the energetic particle sources in our Galaxy, and interstellar environment through which these particles propagate. Uncertainties on hadronic models, ion-nucleon cross sections particular, are currently limiting factor toward obtaining more accurate CR ion flux with calorimetric space-based experiments. We present energy-dependent measurement of inelastic section protons helium-4 nuclei (alpha particles) a...
In this paper, we develop a kW-level high-repetition-rate nanosecond master oscillator power amplifier (MOPA) laser system, employing structure of fiber, Nd:YVO4, and Nd:YAG hybrid amplification. A tunable fiber seed source is used for adjustable pulse repetition frequency width. The Nd:YVO4 pre-amplifier, which dual-end-pumped, achieves high gain while maintaining good beam quality, the high-power side-pumped slab main-amplifier enables efficient rate output can be adjusted within range...

Hexagonal wurtzite InN nanowires are grown via a vapor–liquid–solid (VLS) mechanism with an Au catalyst. Microstructure characterizations of large number demonstrate that the growth direction is governed by variable NH3 flux. at flux 10 standard cubic centimeters per minute (sccm) grow preferentially in hexagonal close-packed (hcp) direction, while those 100 sccm favor hcp ⟨0001⟩ direction. A free energy minimization model proposed to interpret this phenomenon. The first-principles...
We study the thermodynamic properties of color-flavored-locked (CFL) quark matter in finite temperature and strong magnetic field cases within confined-isospin-density-dependent-mass model. find that considering CFL phase star (QS) can significantly influence equation state as well QSs at or under fields. In particular, our results indicate polytropic index becomes anisotropic fields decreases with increment mass different isentropic stages QSs.

Increasing the intensity to which high power laser pulses are focused has opened up new research possibilities, including promising approaches particle acceleration and phenomena such as field quantum electrodynamics. Whilst achievable with a pulse of given can be increased via tighter focusing, focal spot profile also plays an important role in interaction physics. Here we show that spatial-intensity distribution, specifically ratio peak halo surrounding it, is ultraintense solid targets....
Dark Matter Particle Explorer (DAMPE) is a calorimetric-type, satellite-borne detector for observations of high energy electrons, gamma-rays, and cosmic-ray nuclei. Using five years data collected with DAMPE from January 1, 2016 to December 31, 2020, we analyzed the spectrum iron. Detailed studies fragmentation iron in have been performed using Monte Carlo simulations.
Spectra of three-halves harmonic emissions (3/2) from laser-produced plasmas were measured at different angles, including both forward and backward sides, the direction incident laser beams. The /2 emitted carbon–hydrogen (CH) targets was observed to be larger than that aluminum (Al) with same intensity, which supports argument two-plasmon decay (TPD) instability could inhibited by using medium-Z ablator instead CH in direct-drive inertial confinement fusion. Besides, /2–incident intensity...
