Using Facial Landmarks For Lip Motion Interpretation Applications, Kimi S. Wright

Theses and Dissertations

Facial motion, particularly lip movement, carries rich information about human speech that can be leveraged for a variety of computer vision and speech-processing tasks. Unlike other pixel-based methods, this work investigates the use of facial landmarks as a compact, privacy- preserving, and computationally efficient representation for lip-motion analysis. We evaluate landmark-based models across multiple tasks, including visual voice activity detection (VVAD), lip–audio synchroniza- tion, and visual speech recognition (VSR) for liveness detection. Using LRS3-VVAD1 and LRS22 datasets, we demonstrate that landmark-only models can achieve performance comparable to pixel-based systems for VVAD and synchronization, while significantly reducing parameter counts and inference …

GME Publications

One of the most common interventions in the ED and ICU to restore physiologic homeostasis is fluid administration. It is essential for the intensivists and ED physicians to be aware of the physiological characteristics of different fluids and the potential harm associated with their use. In this article, we explore the physiology and pathophysiology of fluid administration in humans, emphasizing how fluid administration can alter acid-base balance, perfusion, osmotic and oncotic pressures, immunologic and inflammatory responses, and hemodynamics. We also discuss fluid resuscitation strategies across common clinical scenarios, such as septic shock, diabetic ketoacidosis, rhabdomyolysis, acute pancreatitis, and acute brain …

When The Muses Went Silent And Almost Died:, Thomas M. Hines

Journal of the Jussi Björling Societies of the USA & UK

What would life be like if there were no fine or performing arts? If music could not be heard in public, if great paintings of famous artists of the past and present could not be seen—in other words, how would we adjust in an esthetically deprived existence? In truth, we could continue to see and hear; nature would still be around us, but the interpretative acuity of our senses would be dulled. Opportunities to witness works of art would not be readily available. Our creative images would be internalized and not reflective of visual or auditory models. It would be …

“I Was So Nervous For Him” – Kerstin Thorborg And Jussi Björling, Nils-Göran Olve

Journal of the Jussi Björling Societies of the USA & UK

Kerstin Thorborg (1896–1970) was a leading mezzo-soprano with the Metropolitan for thirteen seasons, singing twenty roles in 350 performances. Her debut was as Frick in Die Walküre on 21 December 1936 and her final performances in 1950. Fifteen years older than Jussi Björling and born in the same Swedish region Dalarna (Dalecarlia), she enjoyed twenty years of rather solitary retirement there and died ten years after him. Her Met repertoire focused on Wagner so they met rarely on stage, but of course they knew each other well during the years they met professionally (1936–41 and 1945–50). They can be heard …

Augmentasi Tulang Alveolar Dengan Osteogenesis Distraksi Alveolar Ridge Augmentation Using Distraction Osteogenesis, Siti Sarah Aulia Amrullah, Rosida Sani, Nurfadhilah Arifin, Muhammad Ruslin

Dentofasial

Augmentation of the alveolar ridge is widely performed in implant treatment to create predictable function and
esthetics in area with inadequate bone volume. There are some different ways to augment the alveolar ridge.
Distraction osteogenesis is a new method in increasing the width of the ridge and preparing a sufficient bed for implant
or prosthesis. Distraction osteogenesis result in formation of new bone between bone segments that are separated
gradually by incremental traction. Alveolar widening by distraction osteogenesis is an alternative method for
reconstructing alveolar atrophy that is similar to alveolar split grafting but without grafting, which offers many
advantages …

Perbandingan Tingkat Keberhasilan Implan Antara Osteogenesis Distraksi Dengan Autogenous Bone Graft Ratio Of Successful Rate Of Dental Implan Between Distraction Osteogenesis With Autogenous Bone Graft, Irma Drismayanti, Sariatun T, A’La Unas B, Muh. Ruslin, Eri H. Jubhari

Dentofasial

Endosseous dental implants are the treatment of choice for restoring function and reconstructing most edentulous
areas of the maxilla and mandible. One of the most common problems in oral implantology is insufficient bone height
between the alveolar ridge and the mandible canal, as a result of mandibular atrophy from edentulism. Generally,
alveolar bone defects can be reconstructed by either distraction osteogenesis (DO)or autogenous bone grafting
(ABG). This paper discussed implant successful rate in DO versus ABG. DO shows a higher successful rate of implant
than ABG with the result more esthetic, lower rate of infection and bone resorption, no pain …

Various controversies arise on the appropriate treatment time to treat class III
malocclusion at the development age. One reason for delay is that the treatment will
make the treatment period longer. Nevertheless, there are other reasons that believe
the class III malocclusion must be treated as soon as possible. Accuracy of
examination is required to obtain the proper diagnosis to determine treatment
options. Clinical conditions found in the class III malocclusion can be underdeveloped
of maxillae, overdeveloped the mandible, or combination of both. Treatment of class
III malocclusion at the growing age may prevent further severity. A case report of …

Singer’S Choices:, Allan Buchalter

Journal of the Jussi Björling Societies of the USA & UK

On occasion, a composer will place an additional musical staff above a solo singer’s staff so that the singer can choose which version he/she wishes to sing. Sometimes it is a difference of just a few notes, but can also completely change the melodic line, as I’ll illustrate towards the end of this article, with a Björling and Corelli example, after first mentioning a few “oppure” choices (generally abbreviated in scores as “Opp.”).

What oppure is not, is when due to tradition, or for some other reason, a singer takes it upon himself/herself to add something to an aria, duet, …

Thoughts On “O Helga Natt”, Kristian Krogholm

Journal of the Jussi Björling Societies of the USA & UK

“No singer was ever more loved than Jussi Björling,” said Elisabeth Söderström at the big concert in Stockholm 1985 to celebrate his memory. Jussi had a quality that set him apart from everyone else. A voice sent from Heaven. So beautiful, so brilliant, so perfect yet so intensely emotional. Every note he sang went straight into the depths of the heart. That kind of attraction cannot be explained, because it is, and will always remain, a mystery.

What is deepest in the heart of every human being is that which we cannot put into words. And what do we all …

International Journal of Speleology

Speleothems from caves in near-permafrost regions can provide unique insights into the climatic history of temperature-sensitive environments. These regions are often remote and only seasonally accessible, which makes cave monitoring – a requirement for speleothem-based proxy interpretation – challenging. We document ventilation, the infiltration regime, and the isotopic composition of dripwater in Botovskaya Cave in southern Siberia, a host to speleothems previously used to reconstruct Quaternary permafrost dynamics in continental Eurasia. We explore surface and cave temperature records, cave air CO₂ concentration data and stable isotopes in precipitation and dripwater and evaluate infiltration conditions and the sensitivity of speleothems …
