We report on the quasi-linear in field intrachain magnetoresistance in the normal state of a quasi-one-dimensional superconductor Ta$_4$Pd$_3$Te$_{16}$ ($T_c$$sim$4.6 K). Both the longitudinal and transverse in-chain magnetoresistance shows a power-l
aw dependence, $Delta rho$$propto$B$^alpha$, with the exponent $alpha$ close to 1 over a wide temperature and field range. The magnetoresistance shows no sign of saturation up to 50 tesla studied. The linear magnetoresistance observed in Ta$_4$Pd$_3$Te$_{16}$ is found to be overall inconsistent with the interpretations based on the Dirac fermions in the quantum limit, charge conductivity fluctuations as well as quantum electron-electron interference. Moreover, it is observed that the Kohlers rule, regardless of the field orientations, is violated in its normal state. This result suggests the loss of charge carriers in the normal state of this chain-containing compound, due presumably to the charge-density-wave fluctuations.
Globular clusters (GCs) are the oldest stellar system in the Galaxy, in which the millisecond pulsars are widely believed to be the only steady {gamma}-ray emitters. So far 9 {gamma}-ray GCs have been identified and a few candidates such as 2MS-GC01
and IC 1257 have been suggested. In this work, after analyzing the publicly-available Fermi-LAT data we confirm the significant {gamma}-ray emission from 2MS-GC01 and IC 1257 and report the discovery for {gamma}-ray emission from NGC 5904 and NGC 6656 within their tidal radii. Also a strong evidence of significant {gamma}-ray emission is found from FSR 1735. From the observed {gamma}-ray luminosities, the numbers of MSPs that are expected to be present in these GCs are estimated.
