(Massachusetts Institute of Technology, 1993) -
S*: Geometric Multimodal Trajectory Optimization via Apex Interpolating Spiro Splines
(Massachusetts Institute of Technology, 2022-09)Non-heuristic multimodal trajectory optimization is widely considered an intractable holy grail for real-time robotic systems, with the existing state-of-the-art standing at a heuristic hierarchical approach that stacks ... -
s- process enrichment of ultrafaint dwarf galaxies
(Oxford University Press (OUP), 2021)<jats:title>ABSTRACT</jats:title> <jats:p>We study the production of barium (Ba) and strontium (Sr) in ultrafaint dwarf (UFDs) galaxies. Both r- and s- processes produce these elements, and one can infer ... -
S-nitrosation of proteins relevant to Alzheimer's disease during early stages of neurodegeneration
(National Academy of Sciences (U.S.), 2016-03)Protein S-nitrosation (SNO-protein), the nitric oxide-mediated posttranslational modification of cysteine thiols, is an important regulatory mechanism of protein function in both physiological and pathological pathways. A ... -
S-nitrosation of proteins relevant to Alzheimer’s disease during early stages of neurodegeneration
(National Academy of Sciences (U.S.), 2016-04)Protein S-nitrosation (SNO-protein), the nitric oxide-mediated posttranslational modification of cysteine thiols, is an important regulatory mechanism of protein function in both physiological and pathological pathways. A ... -
S-nitrosylation of E3 ubiquitin-protein ligase RNF213 alters non-canonical Wnt/Ca+2 signaling in the P301S mouse model of tauopathy
(Springer Nature, 2019-01)Mutations in the MAPT gene, which encodes the tau protein, are associated with several neurodegenerative diseases, including frontotemporal dementia (FTD), dementia with epilepsy, and other types of dementia. The missense ... -
S-Nitrosylation of PINK1 Attenuates PINK1/Parkin-Dependent Mitophagy in hiPSC-Based Parkinson’s Disease Models
(Elsevier, 2017-11)Mutations in PARK6 (PINK1) and PARK2 (Parkin) are linked to rare familial cases of Parkinson's disease (PD). Mutations in these genes result in pathological dysregulation of mitophagy, contributing to neurodegeneration. ... -
S-Store: a streaming NewSQL system for big velocity applications
(Association for Computing Machinery (ACM), 2014-08)First-generation streaming systems did not pay much attention to state management via ACID transactions (e.g., [3, 4]). S-Store is a data management system that combines OLTP transactions with stream processing. To create ... -
S-Store: streaming meets transaction processing
(Association for Computing Machinery, 2015-09)Stream processing addresses the needs of real-time applications. Transaction processing addresses the coordination and safety of short atomic computations. Heretofore, these two modes of operation existed in separate, ... -
S-wave Splitting Analysis: Covariance Matrix Method and Preliminary Application
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2004)From polarization analysis on a covariance matrix, a method of S-wave splitting analysis is developed, which processes 3-component recordings simultaneously, rather than just 2 horizontal components as done traditionally. ... -
The S. cerevisiae calponin homologue SCP1 regulates stability and organization of the actin cytoskeleton
(Massachusetts Institute of Technology, 2003)Calponins and transgelins are members of a conserved family of actin-associated proteins widely expressed from yeast to humans. While a role for calponin in muscle cells has been described, the biochemical activities and ... -
S.N.A.K.E. : a dynamically reconfigurable Artificial Sensate Skin
(Massachusetts Institute of Technology, 2006)The idea of an Artificial Sensate Skin device that mimics the characteristics and functions of its analogous living tissue whether human or animal is not new. Yet, most of the current related work has been focused in the ... -
S100A9-RAGE Axis Accelerates Formation of Macrophage-Mediated Extracellular Vesicle Microcalcification in Diabetes Mellitus
(Ovid Technologies (Wolters Kluwer Health), 2020)© 2020 American Heart Association, Inc. Objective: Vascular calcification is a cardiovascular risk factor and accelerated in diabetes mellitus. Previous work has established a role for calcification-prone extracellular ... -
S2ADC: A 12-bit, 1.25MS/s Secure SAR ADC with Power Side-Channel Attack Resistance
(Institute of Electrical and Electronics Engineers (IEEE), 2020-04)This paper presents a neural-network-based SAR ADC power side-channel attack (PSA) method and a 12-bit, 1.25MS/s secure SAR ADC whose current equalizers protect the ADC from PSA. A prototype SAR ADC was fabricated in 65nm ... -
The S4 infrastructure management system
(Massachusetts Institute of Technology, 2016)This thesis describes the design and implementation of a system for managing the infrastructure supporting a course relying on a large computer lab. Students' information privacy and security was an important focus in the ... -

S[subscript n]-equivariant sheaves and Koszul cohomology
(Springer, 2014-11)Purpose: We give a new interpretation of Koszul cohomology, which is equivalent under the Bridgeland-King-Reid equivalence to Voisin's Hilbert scheme interpretation in dimensions 1 and 2 but is different in higher ... -
Saccade latency determination using video recordings from consumer-grade devices
(Massachusetts Institute of Technology, 2018)Accurate quantification of neurodegenerative disease progression and neurocognitive decline is an ongoing challenge that muddles efforts to understand and treat these conditions. The golden standard to track neurodegenerative ... -
A sacred architecture for the secular spirit : an institute for mind/body training in New York City
