Mitigating multipath of cellular long-term evolution (LTE) signals for robust positioning in urban environments is considered. A computationally-efficient receiver, which uses a phase-locked loop (PLL)-aided delay-locked loop (DLL) to track the received LTE signals is presented. The DLL uses an orthogonal frequency division multiplexing (OFDM)–based discriminator function to estimate and track ...

Since its discovery, differential linear logic (DLL) inspired numerous domains. In denotational semantics, categorical models of DLL are now commune, and the simplest one is Rel, the category of sets and relations. In proof theory this naturally gave birth to differential proof nets that are full and complete for DLL. In turn, these tools can naturally be translated to their intuitionistic coun...

This paper proposes a digital delay locked loop (DLL) with monotonic line (DL). DLL adopts the calibration mode to reduce non-monotonic effects for coarse-tuning (CTDL) and fine-tuning (FTDL). The detects time of unit, timing resolution CTDL, adjust range FTDL. Thus, can limit overlap between CTDL proposed was implemented using 0.18-μm CMOS process, RMS peak-to-peak jitters were 0.21% 1.72%, re...

Delay locked loops are an attractive alternative to VCO based phase locked loops due to their simpler design and inherent stability [1]-[3]. The primary disadvantage of conventional DLLs is their limited phase range, which limits their application to mesochronous environments. This dual DLL architecture combines several techniques to achieve unlimited phase shift, low jitter and large operating...

When programmers need to modify third-party applications, they frequently do not have access to their source code. In such cases, DLL injection and API hooking are techniques that can be used to modify applications without intervening into their source code. The commonly used varieties of injection and hooking approaches have many practical limitations: they are inconvenient for a programmer to...

Arthropod appendages are thought to have evolved as outgrowths from the body wall of a limbless ancestor. Snodgrass, in his Principles of Insect Morphology (1935), proposed that, during evolution, expansion of the body wall would originate the base of the appendages, or coxopodite, upon which the most distal elements that represent the true outer limb, or telopodite, would develop. The homeobox...

In this paper, a Delay-Locked Loop (DLL) based clock generator is designed which can be used mainly for dynamic frequency scaling. This DLL-based clock generator is found to have low-jitter and can provide the system clock with frequencies in the range of 0.5 to 8 times of reference clock, depending on the workload of the EISC processor. This proposed analog self-calibration method and a phase ...

Notch signaling plays an important role in regulation of innate immune responses and trophoblast function during pregnancy. To identify the role of Notch signaling in preterm labor, Notch receptors (Notch1-4), its ligands (DLL (Delta-like protein)-1/3/4), Jagged 1/2) and Notch-induced transcription factor Hes1 were assessed during preterm labor. Preterm labor was initiated on gestation day 14.5...

Drosophila leg morphogenesis occurs under the control of a relatively well-known genetic cascade, which mobilizes both cell signaling pathways and tissue-specific transcription factors. However, their cross-regulatory interactions, deployed to refine leg patterning, remain poorly characterized at the gene expression level. Within the genetically interacting landscape that governs limb developme...

The intrauterine environment is particularly vulnerable to environmental exposures. We previously established a mouse model that provided evidence for pregnancy complications and placental anti-angiogenesis in response to Aroclor 1254 (A-1254), a mixture of polychlorinated biphenyls (PCBs). Importantly, these effects were observed in IL-10-/-, but not wild type, mice, suggesting that IL-10 defi...
