Die Verschleierung des Ich. Untersuchungen zur naturphilosophischen Poetologie Alfred DĂśblins
Diese Dissertation befasst sich mit den naturphilosophischen Anschauungen Alfred DĂśblins als einer der wesentlichen Quelle seiner Poetologie und Autorschaft bis etwa 1933. Es werden seine einschlägigen Schriften, von den frĂźhen Texten Ăźber Nietzsche, Ăźber z.B. die âGespräche mit Kalypsoâ, dann Berliner Programm, âReise in Polenâ, âDas Ich Ăźber der Naturâ und âDer Bau des epischen Werkesâ bis zu âUnser Daseinâ behandelt. Dabei ging es anfangs um eine Depersonationspoetik, später aber mehr und mehr um die erneute Betonung des Ichs im Sinne einer dialektischen Erweiterung des Verständnisses desselben. Dieses neue Ich-Verständnis soll vor dem Hintergrund der entwickelten Naturphilosophie des Autors verdeutlicht werden
Small Objects Matters in Weakly-supervised Semantic Segmentation
Weakly-supervised semantic segmentation (WSSS) performs pixel-wise
classification given only image-level labels for training. Despite the
difficulty of this task, the research community has achieved promising results
over the last five years. Still, current WSSS literature misses the detailed
sense of how well the methods perform on different sizes of objects. Thus we
propose a novel evaluation metric to provide a comprehensive assessment across
different object sizes and collect a size-balanced evaluation set to complement
PASCAL VOC. With these two gadgets, we reveal that the existing WSSS methods
struggle in capturing small objects. Furthermore, we propose a size-balanced
cross-entropy loss coupled with a proper training strategy. It generally
improves existing WSSS methods as validated upon ten baselines on three
different datasets.Comment: Accepted to WACV 202
Guideline of the Korean Academy of Medical Sciences for Assessing Respiratory Impairment
The presently used impairment rating guidelines in Korea do not accurately reflect the injury in various lung diseases. Therefore, they need to be made more objective and quantitative with new measurements, using indicators to more precisely represent impairment in the major respiratory diseases. We develop a respiratory impairment rating guideline to ensure that the same grade or impairment rating would be obtained regardless of surgeons who determinate it. Specialists in respiratory medicine and thoracic surgeons determined the impairment grades. Moreover, the impairment should be irreversible for more than 6 months. The impairment rating depends on the level of forced vital capacity, forced expiratory volume 1 second, diffusion capacity of carbon monoxide, arterial oxygen pressure, and arterial carbon dioxide pressure. The degree of whole body impairment is defined by each grade: first 81-95%, second 66-80%, third 51-65%, fourth 36-50%, and fifth 21-35%. In conclusion, we develop a respiratory impairment rating guideline for Koreans. Any qualified specialist can easily use it and judge objective scoring
AesPA-Net: Aesthetic Pattern-Aware Style Transfer Networks
To deliver the artistic expression of the target style, recent studies
exploit the attention mechanism owing to its ability to map the local patches
of the style image to the corresponding patches of the content image. However,
because of the low semantic correspondence between arbitrary content and
artworks, the attention module repeatedly abuses specific local patches from
the style image, resulting in disharmonious and evident repetitive artifacts.
To overcome this limitation and accomplish impeccable artistic style transfer,
we focus on enhancing the attention mechanism and capturing the rhythm of
patterns that organize the style. In this paper, we introduce a novel metric,
namely pattern repeatability, that quantifies the repetition of patterns in the
style image. Based on the pattern repeatability, we propose Aesthetic
Pattern-Aware style transfer Networks (AesPA-Net) that discover the sweet spot
of local and global style expressions. In addition, we propose a novel
self-supervisory task to encourage the attention mechanism to learn precise and
meaningful semantic correspondence. Lastly, we introduce the patch-wise style
loss to transfer the elaborate rhythm of local patterns. Through qualitative
and quantitative evaluations, we verify the reliability of the proposed pattern
repeatability that aligns with human perception, and demonstrate the
superiority of the proposed framework.Comment: Accepted by ICCV 2023. Code is available at this

VIM- and IMP-Type Metallo-β-lactamaseâProducing Pseudomonas spp. and Acinetobacter spp. in Korean Hospitals
We determined the occurrence of acquired metallo-β-lactamase (MBL)âproducing bacteria in Korean hospitals. Among the isolates nonsusceptible to imipenem that were collected from 28 hospitals from 2000 to 2001, 44 (11.4%) of 387 Pseudomonas spp. and 38 (14.2%) of 267 Acinetobacter spp. infections produced MBL and had alleles of blaVIM-2 or blaIMP-1. MBL-producing isolates were detected in 60.7% of the hospitals
Degenerate Stars and Gravitational Collapse in AdS/CFT
We construct composite CFT operators from a large number of fermionic primary
fields corresponding to states that are holographically dual to a zero
temperature Fermi gas in AdS space. We identify a large N regime in which the
fermions behave as free particles. In the hydrodynamic limit the Fermi gas
forms a degenerate star with a radius determined by the Fermi level, and a mass
and angular momentum that exactly matches the boundary calculations. Next we
consider an interacting regime, and calculate the effect of the gravitational
back-reaction on the radius and the mass of the star using the
Tolman-Oppenheimer-Volkoff equations. Ignoring other interactions, we determine
the "Chandrasekhar limit" beyond which the degenerate star (presumably)
undergoes gravitational collapse towards a black hole. This is interpreted on
the boundary as a high density phase transition from a cold baryonic phase to a
hot deconfined phase.Comment: 75 page
Molecular and genetic characterization of OSH6 (Oryza sativa Homeobox 6) using dissociation (Ds) insertion mutant rice
Genetic studies of dissociation (Ds) insertion mutant rice plants indicated that ectopic expression of truncated OSH6 (Oryza sativa Homeobox 6) mRNA may be responsible for the mutant phenotype of knotted leaf formation at the peduncle. Additionally, ectopic expression of truncated OSH6 mRNA in the OSH6-Ds mutant plant led to alteration of other homeobox genes including OSH15 in leaf tissues. The OSH6-Ds mutant plant exhibited altered expression of more than 118 genes on a 22K rice microarray in comparison with wild type plants. Of these genes, 20 were up- or down-regulated in both OSH6-Ds and OSH6-overexpressing (OSH6-35S) plants. Especially, OsDof3 was not expressed in floral organs, but was present in the panicles of both OSH6-Ds and OSH6-35S plants. It is assumed that truncated OSH6 transcript might be actively involved in the gene expression during organ development. The genetic relationship between OSH6-Ds and OSH15 suggested that the formation of the extra leaf is independent of OSH6-Ds or OSH15 expression. These results suggest that truncated OSH6 mRNA influences lateral organ growth and development by regulating the expression of specific gene groups.Key words: Oryza sativa Homeobox 6 (OSH6) genes, Ds insertion lines, OSH15 mutant
Repair Using Conventional Implant for Ruptured Annulus Fibrosus after Lumbar Discectomy: Surgical Technique and Case Series
Study DesignA retrospective review of annulus fibrosus repair (AR) using a novel technique with a conventional implant.PurposeThe purpose of this study was to present the feasibility and clinico-radiological outcomes of a novel AR technique using a conventional implant to minimize recurrence following a lumbar discectomy (LD).Overview of LiteratureConventional repair techniques to prevent recurrence following LD have several drawbacks. The AR surgical technique has received little attention as an adjunct to LD.MethodsA total of 19 patients who underwent novel AR following LD, and who were available for follow-up for at least three years, were enrolled in this study. Several variables, including the type and size of disc herniation, and the degree of disc degeneration, were evaluated preoperatively. Postoperatively, the presence of clinical and radiological recurrence of disc herniation was evaluated from pain intensity and functional statuses, as well as an enhanced L-spine magnetic resonance imaging at the final follow-up. The presence of a peripheral hollow rim and inserted anchor mobilization were also evaluated during the follow-up.ResultsDuring follow-ups, there were no recurrences of disc herniation or complications, including neurovascular complications. Pain and functional disability improved significantly after surgery, and the improvement was maintained throughout the three-year follow-up period. No mobilization or implant peripheral hollow rim was observed during the follow-up.ConclusionsThis study examined the feasibility of a novel and easily available annulus implant technique following LD. These results suggest performing AR with this technique may be a valuable alternative for optimizing outcomes, if the procedure is performed in proper candidates
