The Doppler dipole signal dominates the cosmic microwave background (CMB) anisotropy maps obtained by the Wilkinson Microwave Anisotropy Probe (WMAP) mission, and plays a key role throughout the data processing.

ドップラー双極信号は、ウィルキンソン宇宙背景放射異方性探査機(WMAP)ミッションによって得られた宇宙マイクロ波背景放射(CMB)異方性マップにおいて支配的であり、データ処理全体を通じて重要な役割を果たしている。以前、我々は、オリジナルの生のWMAP時系列データ(TOD)における宇宙船の姿勢データと放射計出力のタイムスタンプ間に-25.6ミリ秒のタイミング非同期が存在することを発見した。このずれが、その後のデータ処理で補正されない場合、得られたCMBマップに人工的な四極子成分(l=2)を生じることになる(Liu, Xiong & Li 2010)。最近、Roukema(2010b)は、仮定されるタイミングずれの関数としてTODから再...

In this work, we propose to utilize discrete graph Ricci flow to alter network entropy through feedback control. Given such feedback input can reverse entropic changes, we adapt the moniker of Maxwells Demon to motivate our approach. In particular, it has been recently shown that Ricci curvature from geometry is intrin...
本研究では、離散的グラフリッチフローを用いてフィードバック制御を通じてネットワークエントロピーを変化させることを提案する。このようなフィードバック入力がエントロピー変化を逆転させ得ることから、我々のアプローチの動機付けとして「マクスウェルの悪魔」という呼称を採用する。特に最近、幾何学におけるリッチ曲率がボルツマンエントロピーおよびネットワークの機能的ロバスト性、すなわちランダムな変動が存在する中でも機能を維持する能力と本質的に関連していることが示されている。これにより、離散的リッチフローは、特定のネットワークの基礎的幾何構造を再構成し、スループットとレジリエンスを向上させる自然な手段を提供する。特定のエージェント間で非線形制約を課し...

细胞增殖、凋亡以及肌球蛋白依赖性收缩可在活体组织中产生弹性应力和应变,这些应力和应变可通过细胞拓扑转变和细胞骨架重组引起的内部重排而耗散。此外,细胞和组织可响应力学信号而改变其尺寸。本文研究了在由促进生长的化学因子场诱导的差异性生长背景下,组织可压缩性和内部重排活动对其尺寸和力学调控的作用。我们基于有限弹性与生长理论以及参考映射方法,建立了在欧拉框架下描述组织生长与力学耦合的数学模型。通过在参考映射演化中引入重排速率以纳入组织重排过程,当组织生长和变形具有径向对称性时,可导致弹性能量的耗散。通过对模型进行线性化分析,我们发现应力遵循麦克斯韦型黏弹性松弛行为。重排速率(我们称之为组织流动性)决定了应力松弛时间,而剪切模量与流动性的比值...

最近、大規模分散最適化における効率的な通信のために、研究者らはさまざまな低精度勾配圧縮手法を提案した。これらの研究を基に、我々は通信複雑性を新たな方向から削減することを試みる。具体的には、勾配分布の二つの空間の間に理想的な全単射写像を追求し、圧縮後の勾配がより大きな情報エントロピーを持つようにする。我々の設定では、すべてのサーバーが事前に参照勾配を共有しており、現在の勾配と参照勾配との差分または商として得られる正規化勾配を介して通信を行う。より高い信号対雑音比をもたらす参照ベクトルを各反復で動的に得るために、過去の軌道から情報を後知恵的に抽出・融合し、圧縮に最適な参照を探索する。我々はこれを軌道に基づく正規化勾配(TNG)と呼ぶ。T...

The skew arises because the variability of family sizes is either inherently strong or amplified by population expansions, leading to so-called `jackpot' events. The resulting allele frequency flu...
自然种群常常表现出增强的遗传漂变,这与后代数量分布的高度偏斜一致。这种偏斜源于家族大小的变异性本身较强,或因种群扩张而被放大,从而导致所谓的“ jackpot”事件。由此产生的等位基因频率波动较大,因而对标准的群体遗传学模型提出了挑战,因为这些模型假设后代分布足够集中。虽然可以通过溯祖方法方便地分析时间倒向的中性动力学,但我们对广泛后代分布正向时间动力学的影响仍知之甚少,尤其是在存在选择的情况下。本文采用精确的渐近分析结合标度假设,证明了过度离散的频率轨迹源于传统力量(如选择或突变)与一种针对稀有等位基因的、随时间变化的抽样偏差之间的竞争。这种抽样偏差源自每种等位类型中最大抽样家族大小所具有的特征性时间依赖性。基于这一认识,我们建立...
