人类活动最初从上世纪开始促使地球气候变暖,这已经成为大众公认的科学常识.随着燃煤工厂和电厂的出现,工业社会开始向大气中排放二氧化碳和其它温室气体.后来,机动车也加入到排放行列之中.在这种背景下,生活在工业时代的人类不仅影响大气温室气体的浓度,而且至少在某种程度上要对由此导致的全球变暖趋势负责.然而现在看来,我们的农耕祖先可能早在几千年前就开始使得大气中的这些温室气体含量增加,从而改变全球气候,比任何人想象的都早得多.

Bound states in the continuum （BICs） are perfectly localized resonances despite embedding in the continuum ***,an isolated BIC is very sensitive to the structure ***,we report merging acoustic BICs in a single open resonator,robust against the structure *** find that both symmetry-protected BIC and friedrich-Wintgen BIC are sustained in a single coupled waveguide-resonator *** varying the height and length of the resonator,these two BICs move toward each other and merge into a single one at a critical *** to an individual BIC,the merged BIC is robust against fabrication error because its Q-factor is proportional to ΔL-4,whereΔL embodies the structure *** essence of this extraordinary phenomenon is perfectly explained by the two-and three-level approximations of the effective nonHermitian ***,we present direct experimental demonstrations of the moving and merging of BICs in a coupled 3D waveguide-resonator,which are evidenced by the vanishing of the linewidth of fano resonance in the transmission *** results may find exciting applications in designing high-quality acoustic sources,sensors and filters.

The flux of geoneutrinos at any point on the Earth is a function of the abundance and distribution of radioactive elements within our planet. This flux has been successfully detected by the 1-kt Kam LAND and 0.3-kt Borexino detectors, with these measurements being limited by their low statistics. The planned 20-kt JUNO detector will provide an exciting opportunity to obtain a high statistics measurement, which will provide data to address several questions of geological importance. This paper presents the JUNO detector design concept, the expected geo-neutrino signal and corresponding backgrounds. The precision level of geo-neutrino measurements at JUNO is obtained with the standard least-squares method. The potential of the Th/U ratio and mantle measurements is also discussed.

This report presents our experience with T therapy in a cohort of T-deficient men on active surveillance （AS） for Gleason 3 ＋ 3 and Gleason 3 ＋ 4 prostate cancer （PCa）. A retrospective chart review identified 28 men with T deficiency who underwent T therapy （T group） for at least 6 months while on AS for PCa. A comparison group of 96 men on AS for PCa with untreated T deficiency （no-T group） was identified at the same institution. The AS protocol followed a modified Epstein criteria and allowed inclusion of men with a single core of low-volume Gleason 3 ＋ 4 PCa. Mean age was 59.5 and 61.3 years, and mean follow-up was 38.9 and 42.4 months for the T and no-T groups, respectively. Of all 28 men in the T group, 3 （10.7%） men developed an increase in Gleason score while on AS. Of 22 men in the T group with Gleason 3 ＋ 3 disease, 7 （31.8%） men developed biopsy progression including 3 men （13.6%） who developed Gleason 3 ＋ 4 PCa. Of 6 men with Gleason 3 ＋ 4 disease at baseline, 2 （33.3%） men developed an increase in tumor volume, and none developed upgrading beyond Gleason 3 ＋ 4. All 96 men in the no-T group had Gleason 3 ＋ 3 disease at baseline and, 43 （44.7%） developed biopsy progression, including 9 men （9.38%） with upgrading to Gleason 7 （3 ＋ 4）. Biopsy progression rates were similar for both groups and historical controls. Biopsy progression in men on AS appears unaffected by T therapy over 3 years. Prospective placebo-controlled trials of T therapy in T-deficient men on AS should be considered given the symptomatic benefits experienced by treated men.
