در این مقاله یک الگوریتم واهمامیخت کور با استفاده از روش منظم‌سازی تغییر کلی (TV)، به­منظور خوانش بسیاردقیق­تر زمان رسید نسبی فازهای متفاوت امواج زلزله  به‌کار گرفته شده است. در این روش اثر چشمه و تضعیف به­صورت تابعی گاوسی در نظر گرفته شده و همراه با زمان رسید فازهای متفاوت برآورد می­شود. به‌جای روش نرم-1 مرسوم برای TV در مقاله از تابع پتانسیل تنک‌‌کننده­تر ، برای واضح­تر کردن زمان رسید فازها ا...

We present a novel method for reconstructing weak lensing mass or convergence maps as probe to study non-Gaussianities in the cosmic density field. While previous surveys have relied on flat-sky approximation, forthcoming Stage IV will cover such large areas with field of view (FOV) motivate reconstruction sphere. Here, we an improved Kaiser-Squires (KS+) inversion using HEALPix pixelisation sp...

Measurements of seismic anisotropy constitute a very important tool for examining patterns of flow and mineral properties in the Earth’s mantle. A popular strategy for gaining insight into upper mantle processes is to examine the splitting of SK(K)S phases and interpret them in terms of upper mantle anisotropy and deformation; in such studies, any contribution to splitting from anisotropy in th...

Two-component systems (TCSs) are key elements in bacterial signal transduction in response to environmental stresses. TCSs generally consist of sensor histidine kinases (SKs) and their cognate response regulators (RRs). Many SKs exhibit autokinase, phosphoryltransferase and phosphatase activities, which regulate RR activity through a phosphorylation and dephosphorylation cycle. However, how SKs...

RATIONALE AND OBJECTIVE The set partitioning in hierarchical trees (SPIHT) wavelet image compression algorithm with the human visual system (HVS) quantization matrix was investigated using x-ray coronary angiograms. We tested whether the HVS quantization matrix for the SPIHT wavelet compression improved computer model/human observer performance in a detection task with variable signals compared...

[1] Anomalous boundary layer structure at the core-mantle boundary (CMB) is investigated using a global set of broadband SKS and SPdKS waves from permanent and portable broadband seismometer arrays. SPdKS is an SKS wave that intersects the CMB at the critical angle for ScP, thus initiating a diffracted P wave (Pdiff) along the CMB at the core entry and exit locations. The waveshape and timing o...
