Time delay estimation or Time-Difference-Of-Arrival estimates is a critical component for multiple localization applications such as multilateration, direction of arrival, and self-calibration. The task is to estimate the time difference between a signal arriving at two different sensors. For the audio sensor modality, most current systems are based on classical methods such as the Generalized Cro
This paper suggests an approach to solving the time-of-arrival self-calibration problem for imbalanced problems, where there is a low number of receivers but many senders. The idea is to solve several subproblems created by only using data relating to four receivers. The solutions are then clustered according to a proposed metric in order to remove failed reconstructions. They are then combined in
IMPORTANCE During the past decade, spinal surgical procedures have been increasingly performed on an ambulatory basis, a change in clinical practice supported only by observational evidence thus far. There have been no randomized clinical trials (RCTs) comparing ambulatory care with inpatient care after any spinal surgery. OBJECTIVE To assess whether ambulatory care is noninferior to overnight hos
Appropriate time discretization is crucial for real-time applications of numerical optimal control, such as nonlinear model predictive control. However, if the discretization error strongly depends on the applied control input, meeting accuracy and sampling time requirements simultaneously can be challenging using classical discretization methods. In particular, neither fixed-grid nor adaptive-gri
Rieger syndrome is an autosomal dominant human disorder affecting eye, tooth and umbilical development, andwhose primary morbidity is the 50% occurrence of glaucoma in affected individuals. The identification of etiologicmutations in the PITX2 gene and its encoded protein, solurshin, inspired the development of a transgenic animal thatmight serve as a model for this disorder. In addition, the more
Att ställa om från fossila bränslen inom sjöfartssektorn kommer att bli ännu svårare än att vända en oljetanker. Det övergripande syftet med denna avhandling, som är förankrad i sustainability transitions-litteraturen, är att öka den nuvarande förståelsen för hur multiskalära uppifrån-och-ner- samt nerifrån-och-upp-processer påverkar sociotekniska förändringar som bidrar till minskade koldioxidutsShifting away from fossil fuels in the maritime shipping sector promises to be even more difficult than turning an oil tanker. Anchored in the sustainability transitions literature, the overall aim of this thesis is to advance the current understanding of how multi-scalar top-down and bottom-up processes influence socio-technical change towards decarbonisation of the global maritime shipping secto
Trichomoniasis is a sexually transmitted infection (STI) caused by the microphilic parasitic protist Trichomonas vaginalis. The common sign and symptoms of the infection are vaginitis, cervicitis, dysuria, urethritis, vaginal discharge with foul smell, pelvic inflammatory disease (PID), dyspareunia, preterm delivery, and low birth weight. It plays a vital role in the transmission and acquisition o
Since the normalization of Sino-Korean diplomatic relations in 1992, many South Koreans have moved to China for business, education, and other purposes. There they have encountered Korean-Chinese; ethnic Koreans who have lived in China for decades. This has lead to 'intra-ethnic conflict' which has divided Korean communities.
This book offers a first look at transnational education corporations, new firms that operate international schools. The quiet rise of transnational education corporations – or TECs – has implications for education systems around the globe, as corporate interests gain a greater stake in the way schools operate. The story of their ascendance links government policies in one corner of the world with
Recent years have seen the emergence of critical studies pro-duced by third- generation Displaced Persons (hereafter DPs),questioning ethno-nationalist historical narrations, hegemonicin the community. Yet, in the Ukrainian diaspora in Canada, suchstudies have been absent. Kassandra Luciuk’s current study iswritten by someone raised in the political elite of the Ukrainianethno-nationalist communit

South Korea's democratization appeared to mean the demise of a harsh political style that was dominant during the country's rapid industrialization. The 2012 presidential election placed in power a leader who deliberately invoked the style and policies of that predemocratic period. The election saw a sharp divide between voters aged fifty and over, who overwhelmingly supported the winning candidat
The last decade has witnessed the emergence of a new type of player in primary and secondary education in the Asia Pacific. This type is the transnational corporation (TNC) specializing in schools. I refer to these organizations as Education TNCs, which I define as private firms that operate for-profit schools in multiple countries. This paper examines the rise of Education TNCs that run internati
The Axenfeld-Rieger syndrome is autosomal dominant and affects the development of eyes, teeth, and gut. The eyemanifestations include cloudy corneas, tearing, glaucoma, iris hypoplasia, irido-corneal adhesion, and occasionallymegalocornea. Mutations have been found in the genes for transcription factors PITX2 and FOXC1. Mice homozygousfor disruption of PITX2 are embryonic lethal from heart malform
Purpose: To analyse clinical characteristics and risk factors for post-operative endophthalmitis (POE) in a Swedish patient insurance database and compare prevalence of POE with two national quality registers. Methods: We analysed 218 medical records of patients who claimed compensation for POE following ocular surgery from 2010 to 2020. The data were cross-referenced with national quality registe
Background: Men with prostate cancer (PC) may experience significant psychosocial distress from physical symptoms, treatment side effects, or fear of recurrence. However, little is known about the long-Term risk of anxiety disorders in men with PC. Methods: A national cohort study was conducted of 180189 men diagnosed with PC during 1998-2017 and 1801890 age-matched population-based control men in
What do calls for food sovereignty look like in a context with little agriculture and limited opportunities for resistance? Despite the small number of producers, the lack of overt resistance, and the absence of ties to the global food sovereignty movement, food activists in Singapore articulate a quiet but radical critique of how the state manages globalization. This critique contains elements of
