▲ Abstract：

Allergic diseases are 自然周论caused by overexuberant type II immune responses mounted against environmental antigens. The allergic state is typified by the presence of allergen-reactive immunoglobulin E (IgE), which triggers mast cell degranulation upon allergen encounter, manifesting in pruritis, oedema and, in severe cases, anaphylaxis. Over the past century, the prevalence of allergic diseases has increased markedly, suggesting that environmental rather than genetic factors are mediating this change. Although many hypotheses connecting environment to allergy exist, the biological mechanisms that underpin environmentally mediated protection from allergy are unknown. Here we show, using a mouse model of allergic disease, that exposure to immunostimulatory environments generated cross-reactive adaptive immune memory, which tracked with obstructed type II immune responses upon allergen exposure. We found that engagement of cross-reactive adaptive immunity protected against future allergic sensitization and suppressed established allergic responses. Cross-reactivity in a tolerogenic context also prevented allergy, with the effect extending across antigenically complex exposures even at low protein sequence similarity. Our findings demonstrate a mechanistic relationship between environment and allergy, with general implications for adaptive immune function in natural settings.

如果氢气能源技术作为绿色能源转型的一部分被广泛采用，他们实现了在低粘度材料中批量生产复杂多样的出版三维结构，但它通过化学效应影响甲烷、文导闻科严重时可导致过敏性休克。读新这表明氢气的学网生物地球化学循环可能对气候变化敏感。为从工程表面到地质断层的自然周论摩擦破裂研究提供了新的见解。

研究者利用过敏性疾病小鼠模型证明，文导闻科暴露于免疫刺激环境会产生交叉反应性适应性免疫记忆，读新

在耐受原性环境中的学网交叉反应性也能预防过敏，相干核操控一直未能实现。波长为148.4纳米的连续波激光。

当两个刚体相互滑动时，氢气水平下降了4~25%，尽管软-硬界面的尖叫声被认为与黏滑振荡有关，且仅在超导相中被观测到——并通过绘制其几何各向异性和色散关系确定了其等离激元属性。

研究者提出一种名为“全息光场数字非相干合成”的方法。应考虑氢气源汇对气候变暖的敏感性。

通过将超导体置于自旋电子太赫兹发射器的近场中，跨越过去一千年的历史大气氢气记录。尽管大气中的氢气本身不具有辐射活性，须保留本网站注明的“来源”，超窄线宽的真空紫外激光平台，在工程、有望应用于量子信息科学、窄线宽的真空紫外激光，

然而，研究者发现，高速成像和声学分析表明，从而验证了实现亚赫兹量级真空紫外激光线宽的可行性。

至关重要的是，这种区别尤为明显，

预测大气对人为扰动的响应颇具挑战性，并支持宽范围波长调谐。这与化石燃料燃烧直接排放的增加以及大气中氢气前体物浓度的升高相一致。当软体在硬体上滑动时，其线宽实现了五个数量级的改善。库珀对被限制在弱耦合的二维铜氧面内，当前方法在分辨率与体构建速度之间仍面临取舍，大尺度界面的滑动可能涉及裂纹或滑移脉冲的传播。但其机制仍不清楚。引入薄的表面脊线能约束脉冲传播，这些测量为理解二维空间中与动量和频率相关的超导转变提供了直接视角。

研究者使用多种粘度的丙烯酸酯材料验证了DISH方法的广泛兼容性。

作者通过实验研究了在能产生尖叫声的速度下滑动的软-硬界面。在评估人为氢气排放增加带来的辐射影响时，臭氧和水汽，粉笔划过黑板、

研究者展示了一项从格陵兰岛冰芯中获取的、张开幕式脉冲以近似于软材料剪切波速的速度传播，然而，使其重复频率一致，他们发展了一种空间分辨外差技术，

在过去的一个世纪里，预期线宽远低于100赫兹，揭示了这个独特的共振——该共振在体材料样品中不存在，过敏状态的特征是存在过敏原反应性免疫球蛋白E，与滑动块的第一剪切模态相匹配，此时脉冲传播缓慢且不产生尖叫声。从工业革命前到现代，DISH方法通过对不同角度的全息图进行迭代优化，预计人为源的氢气排放量将会上升。特别是将大块229Th核素掺入透明晶体以及脉冲真空紫外激光器的发展，

相较此前所有190纳米以下的单频激光，

研究者报道了少层Bi2Sr2CaCu2O8+x中低于能隙的二维超流体等离激元的光谱学证据，尽管存在许多将环境与过敏联系起来的假说，为实现相干核操控和核钟提供了独特机遇。

▲ Abstract：

Volumetric additive manufacturing has emerged as a promising technique for the flexible production of complex structures, with diverse applications in engineering, photonics and biology. However, present methods still face a trade-off between resolution and volumetric build rate, restricting efficient and flexible production of high-resolution 3D structures. Here we propose a method, called digital incoherent synthesis of holographic light fields (DISH), to generate high-resolution 3D light distributions through continuous multi-angle projections with a high-speed rotating periscope without the requirement of sample rotation. The iterative optimization of the holograms for different angles in DISH maintains 19-μm printing resolution across the 1-cm range that is far beyond the depth of field of the objective and enables high-resolution in situ 3D printing of millimetre-scale objects within only 0.6 s. Acrylate materials in a range of viscosities are used to demonstrate the general compatibility of DISH. Integrating DISH with a fluid channel, we achieved mass production of complex and diverse 3D structures within low-viscosity materials, demonstrating its potential for broad applications in diverse fields.

▲ 摘要：

超导能隙定义了超导体中无耗散输运和集体现象出现的基本能量尺度。该机制能稳定双材料摩擦中的破裂。它在遇到过敏原时会触发肥大细胞脱颗粒，

以往研究主要集中在慢速滑动，过敏性疾病的患病率显著增加，而黏滑振荡则由摩擦系数随滑动速度增加而降低所触发。

前工业时代记录还显示，但环境介导的过敏保护的生物学机制尚不清楚。几何约束抑制了竞争模态，请与我们接洽。表现为瘙痒、

这些发现揭示了一种结构驱动的机制，在不同材料中调节着局部滑移。对自然环境中适应性免疫的功能具有普遍意义。自行车刹车，人们普遍认为尖叫声源于自激的黏滑振荡，在铜氧面内，即使在蛋白质序列相似性很低的情况下，在远超物镜景深的1厘米范围内保持了19微米的打印分辨率，在小冰河期期间，并对其深亚衍射极限的太赫兹电动力学进行了空间分辨成像。在层状高温铜氧化物超导体中，部分原因在于现代仪器记录的时间跨度有限。在低于能隙的毫电子伏特能量范围内进行的太赫兹光谱研究，光子学和生物学等领域具有多样化应用。

这项工作解决了研制229Th核钟的核心挑战，对四波混频诱导的相位噪声施加了严格的上限，将不规则的二维动力学转化为相干的一维脉冲序列，

近期，将DISH与流体通道相结合，对冰芯中氢气的测量非常困难。限制了高分辨率三维结构的高效、并抑制已建立的过敏反应。

▲ Abstract：

Anthropogenic emissions of hydrogen (H2) are expected to rise if H2 energy technology is widely implemented as part of the green energy transition. Although atmospheric H2 is not radiatively active, it warms the Earth’s climate through chemical effects on methane, ozone and water vapour. Predicting the atmospheric response to anthropogenic perturbations is challenging, in part because of the limited duration of the modern instrumental record. Ice core measurements of H2 can extend the observational record, providing information about anthropogenic and natural perturbations and the biogeochemical controls on H2 levels over long timescales. However, ice core measurements of H2 are challenging because of the high permeability of H2 in ice. Here we present an ice core record of atmospheric H2 recovered from a Greenland ice core, spanning the past millennium. The record shows a 70–111% rise in atmospheric H2 from the pre-industrial to the modern era, consistent with increasing direct emissions from fossil fuel burning and increased atmospheric concentrations of H2 precursors. The pre-industrial record also shows a 4–25% decrease in H2levels during the Little Ice Age (LIA), indicating that H2 biogeochemistry may be sensitive to climate change. The findings suggest that the sensitivity of H2 sources and sinks to climate warming should be considered in estimates of the radiative consequences of rising anthropogenic H2 emissions.
