Chapped lips, characterized by drying and cracking, remain a prevalent concern. Identifying the root causes of lip chapping is crucial for developing effective treatments. We examined the lateral packing structure of intercellular lipids (ICL) in the lip stratum corneum (SC) by low-flux electron diffraction (LFED) to…

1## INTRODUCTION The lips (labia oris) form an extension from the mucosal membrane to the outer skin. These vermilion borders are the only part of the facial anatomy where the oral mucosa is permanently exposed to the environment.[srt12814-bib-0001] As such they are highly susceptible to environmental exposure, such as…

'Nazanin Bahrololumi'] Background Lip prints are verified to be unique to an individual and stable over time; hence they have potential for human identification purposes. The aim of this study was to assess the individuality and variability of lip prints in an Iranian population for the first time. We also sought to…

In this paper some of the different techniques used to localize the lips from the face are discussed and compared along with its processing steps. Lip localization is the basic step needed to read the lips for extracting visual information from the video input. The techniques could be applied on asymmetric lips and…

'Jeffrey R. Wozniak' 'Claire D. Coles' 'Raja Mukherjee' 'Michael Suttie'] Abstract—Lip segmentation plays a crucial role in various domains, such as lip synchronization, lip-reading, and diagnostics. However, the effectiveness of supervised lip segmentation is constrained by the availability of lip contour in the…

Speech is an intrinsically multisensory signal and seeing the speaker’s lips forms a cornerstone of communication in acoustically impoverished environments. Still, it remains unclear how the brain exploits visual speech for comprehension and previous work debated whether lip signals are mainly processed along the…

Lip reading is used to understand or interpret speech without hearing it, a technique especially mastered by people with hearing difficulties. The ability to lip read enables a person with a hearing impairment to communicate with others and to engage in social activities, which otherwise would be difficult. Recent…

Methods have been used for identification of human by recognizing lip prints. Human lips have a number of elevation and depressions features called lip prints and examination of lip prints is referred to as cheiloscopy. Lip prints of each human being are unique in nature like many others features of human. In this…

Cross-modality generation is an emerging topic that aims to synthesize data in one modality based on information in a different modality. In this paper, we consider a task of such: given an arbitrary audio speech and one lip image of arbitrary target identity, generate synthesized lip movements of the target identity…

1## INTRODUCTION Motor function of the lips is an oral motor activity (Baum & Bodner, ; Kikutani et al., ; Schimmel, Ono, et al., ; Tallgren & Tryde, ). The lips are composed of multiple muscles and perform complex movements through their linkage (van Lieshout, ). The lips constitute an articulatory organ and an…

Lip reading has witnessed unparalleled development in recent years thanks to deep learning and the availability of largescale datasets. Despite the encouraging results achieved, the performance of lip reading, unfortunately, remains inferior to the one of its counterpart speech recognition, due to the ambiguous nature…

Magnified vision of one’s body part has been shown to improve tactile acuity. We used an anesthetic cream (AC) to explore this effect. In Experiment 1, application of AC caused an increase in perceived lip size. As perceived lip size increased, tactile discrimination (as assessed by two-point discrimination) improved.…

Successful lip reading requires a mapping from visual to phonological information [1]. Recently, visual and motor cortices have been implicated in tracking lip movements (e.g. [2]). It remains unclear, however, whether visuo-phonological mapping occurs already at the level of the visual cortex, that is, whether this…

Chemoproteomics is a key technology to characterize the mode of action of drugs, as it directly identifies the protein targets of bioactive compounds and aids in developing optimized small-molecule compounds. Current unbiased approaches cannot directly pinpoint the interaction surfaces between ligands and protein…

Lip prints are patterns formed by lines or fissures along the outer surface of the lips and their study is known as cheiloscopy. It is a well-accepted tool for human identification, an essence of any forensic investigations.1 Lip prints are individualistic and persistent. Hence, it is a reliable tool for personal…

Phospholipid synthesis and fat storage as triglycerides is regulated by lipin phosphatidic acid phosphatases (PAPs), whose enzymatic PAP function requires association with cellular membranes. Using hydrogen deuterium exchange mass spectrometry, we find mouse lipin 1 binds membranes through an N-terminal amphipathic…

pH plays versatile roles in both biology and chemistry. For instance, pH can regulate the long-range electron transfer (ET) in many proteins. However, the mechanistic basis of many pH-dependent long-range ET processes remain unclear. In this study, we unravel the critical role of pH in accelerating the long-range ET in…

Using the CHARMM36 lipid force field, this investigation employs atomistic molecular dynamics simulation to examine how variations in phosphatidylcholine (PC) lipid composition in murine splenic cancer cells affect membrane properties. While cancer-related alterations in membrane lipid composition are well-established…

The permeation of small molecules across biological membranes is a crucial process that lies at the essence of life. Permeation is involved not only in the maintenance of homeostasis at the cell level but also in the absorption and biodistribution of pharmacologically active substances throughout the human body.…

Lipid nanoparticle RNA (LNP-RNA) formulations are used for the delivery of vaccines and other therapies. RNA molecules are encapsulated within their interior through electrostatic interactions with positively charged lipids. The identity of the lipids that present at their surface play a role in how they interact with…

The solid-electrolyte interphase (SEI) is crucial to the electrochemical performance of all-solid-state batteries (ASSBs). Theoretical characterization of SEI properties will help understand the origin of interfacial stability (and instability) between solid electrolytes and electrodes. Among solid electrolytes for…
