Outcomes in the emergency endovascular repair of blunt thoracic aortic injuries

Abstract Thoracic aorta blunt injury (BAI) is a highly lethal lesion. A large number of victims die before obtaining emergency care. Thoracic endovascular aneurysm repair (TEVAR) is a less invasive method compared with open surgery and may change protocols for BAI treatment. This retrospective study was developed to evaluate the potential issues about thoracic endografting in the management of these patients. Twenty-seven patients with a BAI underwent aortic stent grafting. Intervention was preceded by the treatment of more urgent associated lesions in nine cases. In-hospital mortality was 7.4%. No paraplegia or ischemic complications developed because of the coverage of the left subclavian artery. In one case (3.2%), a type I endoleak was detected, proximal endograft infolding in two cases (7.4%) and endograft distal migration in further two cases were detected during follow-up (6-110 months). Thoracic endovascular aneurysm repair of BAI showed encouraging results in terms of perioperative mortality and morbidity. Concerns still remain about the potential mid- and long-term complications in younger patients

Complete Monotonicity of classical theta functions and applications

We produce trigonometric expansions for Jacobi theta functions\\ $\theta_j(u,\tau), j=1,2,3,4$\ where $\tau=i\pi t, t > 0$. This permits us to prove that\ $\log \frac{\theta_j(u, t)}{\theta_j(0, t)}, j=2,3,4$ and $\log \frac{\theta_1(u, t)}{\pi \theta'_1(0, t)}$ as well as $\frac{\frac{\delta\theta_j}{\delta u}}{\theta_j}$ as functions of $t$ are completely monotonic. We also interested in the quotients $S_j(u,v,t) = \frac{\theta_j(u/2,i\pi t)}{\theta_j(u/2,i\pi t)}$. For fixed $u,v$ such that $0\leq u < v < 1$ we prove that the functions $\frac{(\frac{\delta}{\delta t}S_j)}{S_j}$ for $j=1,4$ as well as the functions $-\frac{(\frac{\delta}{\delta t}S_j)}{S_j}$ for $j=2,3$ are completely monotonic for $t \in ]0,\infty[$.\\ {\it Key words and phrases} : theta functions, elliptic functions, complete monotonicity.Comment: 19 page

PENDAMPINGAN DALAM UPAYA MENURUNKAN PERILAKU PROKRASTINASI AKADEMIK SISWA MELALUI SELF-MANAGEMENT DI SMK

Prokrastinasi akademik adalah kecenderungan untuk menunda-nunda tugas akademik tanpa alasan yang rasional. Permasalahan yang dihadapi oleh mitra adalah banyaknya siswa yang memiliki masalah prokrastinasi akademik. Hal ini ditunjukkan dengan adanya keterlambatan pengumpulan tugas oleh siswa, banyak guru mengeluh karena siswa sering telat mengumpul tugas, ada siswa yang tidak mengerjakan tugas, dan membolos untuk menghindari mengerjakan tugas. Solusi yang ditawarkan dalam pengabdian ini adalah pendampingan dalam upaya menurunkan perilaku prokrastinasi akademik siswa melalui self management di SMK Bina Banua Banjarmasin. Metode pelaksanaan kegiatan pengabdian ini berupa Pendampingan. Adapun rangkaian kegiatan terdiri dari pertemuan I: pre-test, memotivasi mitra, tata-tertib kegiatan, dan menyampaikan materi. &nbsp;Pertemuan II: menetapkan tujuan yang spesifik, terukur, dan dapat dicapai.

Conceptualization of Space within the Tang Landscape Quatrain

The thesis explores the poet’s creation of conceptualized space within the Tang landscape quatrain in the Tang dynasty (618-907) by usage of literary techniques, the focal point being that of temporal and spatial progression to create dynamic and static space. “Space” within the thesis is defined as the “matrix of which forms emerge, medium in which they are related,” a mentalization and visualization of breadth, depth, and width created within the artistic medium. I argue that the concision of Classical Chinese allows the poet to transcend the linguistic limitations imposed by rules of verse to create boundless, semantic space by constructing vivid tableaus of scene and emotion. In Classical Chinese, there are no verb tenses, no indication of plurality in nouns, and no gender or cases for pronouns. The poet must use language to mold intangible form into tangible existence. The deliberate application of ambiguity is a vital component in the creation of multi-layered dimensions of space within Classical Chinese poetry. The Tang dynasty is often known as the golden age of Chinese poetry, dominated by the emergence of new innovations and form as poetry writing became more ubiquitous. The breaking from traditional rules of verse allowed the poet to uniquely utilize space to further their reflections in their poetry. The thesis examines the poet’s creation of spatiality through two lenses of spatiality: creation of external space through landscape, and secondly, the creation of internal space through mental reflection upon that very landscape. The Tang poet approaches the landscape not only as a place setting, but also as an entire subliminal entity in which he aims to capture with his senses and perceptions to create space in which the reader can visualize. The descriptive poetry of the landscape quatrain is simply not a limitation as a medium of visual communication as Tang poets infuse layers of meaning with the economy of a few characters. The significance of framing this study within traditional poetic concerns is to understand the intersections of nature, landscape, literary technique, and aesthetic experience. There has been much academic scholarship on the poetry of the High Tang by scholars such as James J. Y. Liu, Stephen Owen, Burton Watson, just to name a few. However, the objective of this thesis is to offer a new perspective through the lens of spatial creation. Quatrains written by famous Tang poets, Li Bai (701-762), Wang Wei (701-761), and Meng Haoran (689-740) are selected to illustrate how the technique of progression is uniquely utilized to create depth and perspective of space.Asian Studie

Boronyl mimics gold: a photoelectron spectroscopy study

Previous studies have found that gold atom and boronyl bear similarities in bonding in many gas phase clusters.\footnote{H.-J. Zhai, C.-Q. Miao, S.-D. Li, L.-S. Wang, J. Phys. Chem.

Res. 2014, 47, 2435-2445}\ B$_{10}$(BO), B$_{12}$(BO), B$_{3}$(BO)$_{n}$ (n=1, 2) were found to possess similar bonding and structures to B$_{10}$Au, B$_{12}$Au, B$_{3}$Au$_{n}$ (n=1, 2), respectively. During the recent photoelectron spectroscopy experiments, the spectra of BiBO$^{-}$ and BiAu$^{-}$ clusters are found to exhibit similar patterns, hinting that they possess similar geometric structures. While BiAu$^{-}$ is a linear molecule, BiBO$^{-}$ is also linear. The similarity in bonding between BiBO$^{-}$ and BiAu$^{-}$ is owing to the fact that Au and BO are monovalent $\sigma$ ligands. The electron affinities are measured to be 1.79$\pm$0.04eV for BiBO$^{-}$ and 1.36$\pm$0.02eV for BiAu$^{-}$. The current results provide new examples for the BO/Au isolobal analogy and enrich the chemistry of boronyl and gold.\
