Following the Second World War, a massive land reclamation project to boost Japan's rice production capacity led to the transformation of the shallow lagoon of Hachirogata in Akita Prefecture into a ...seventeen-thousand-hectare expanse of farmland. In 1964, the village of Ogata-mura was founded on the empoldered land inside the lagoon and nearly six hundred pioneers from across the country were brought to settle there. The village was to be a model of a new breed of highly mechanized, efficient rice agriculture; however, the village's purpose was jeopardized when the demand for rice fell, and the goal of creating an egalitarian farming community was threatened as individual entrepreneurialism took root and as the settlers became divided into political factions that to this day continue to struggle for control of the village. Based on seventeen years of research, this book explores the process of Ogatamura's development from the planning stages to the present. An intensive ethnographic study of the relationship between land reclamation, agriculture, and politics in regional Japan, it traces the internal social effects of the village's economic transformations while addressing the implications of national policy at the municipal and regional levels.
This volume examines one of Rome's most influential churches: the principal basilica dedicated to St Paul. Nicola Camerlenghi traces nearly two thousand years of physical transformations to the ...church, from before its construction in the fourth century to its reconstruction following a fire in 1823. By recounting this long history, he restores the building to its rightful place as a central, active participant in epochal political and religious shifts in Rome and across Christendom, as well as a protagonist in Western art and architectural history. Camerlenghi also examines how buildings in general trigger memories and anchor meaning, and how and why buildings endure, evolve, and remain relevant in cultural contexts far removed from the moment of their inception. At its core, Saint Paul's exemplifies the concept of building as a process, not a product: a process deeply interlinked with religion, institutions, history, cultural memory, and the arts. This study also includes state-of-the-art digital reconstructions synthesizing a wealth of historical evidence to visualize and analyze the earlier (now lost) stages of the building's history, offering glimpses into heretofore unexamined parts of its long, rich life.
High‐performance Mura artifact reduction (De‐Mura) processing is developed and integrated in display drivers for raising panel yield. The proposed De‐Mura processing, designed to compensate an ...active‐matrix organic light‐emitting diode (AMOLED) panel's luminance Mura (L‐Mura) and color Mura (C‐Mura), shows excellent display performance, and the major display properties include a diminished luminance nonuniformity from about 50% to about 10% under different gray levels, and an improved visually imperceptible color nonuniformity. Among 500 pieces of 5.83” (1128×2436, 460 PPI) retina AMOLED panels, panel yield is improved up to 96.8%. Our works reveals an effective external De‐Mura solution integrated in display drivers for panel factories and module suppliers to obtain high panel yield.
Mura artifacts reduction (De‐Mura) processing, with a high performance for low grayscales, is developed and integrated in display drivers for active‐matrix organic light‐emitting diode (AMOLED) ...display. The proposed De‐Mura processing, designed to compensate an AMOLED panel's luminance Mura (L‐Mura) and color Mura (C‐Mura), shows excellent display performance, and the major display properties include a diminished luminance non‐uniformity under low grayscales (<= Gray 16) and low luminous brightness (<= 2 cd/m 2 ), and an improved visually imperceptible color non‐uniformity. Our works reveals an effective solution to work around the inevitable difficulties of optical measurement of AMOLED panels under low luminous brightness.

When the picture of L255 is pressed or slid, the cell gap is changed and the arrangement of liquid crystal molecules(LC) is disordered, resulting in the decrease of the brightness of the ...corresponding position, which cannot be recovered within the specified time (≤5s), it is called trace Mura. In this paper, the principle of trace Mura is introduced in detail, and a new simulation model is proposed. Using TechWiz software, the risk of trace Mura can be accurately simulated and quantified, and the simulation results are consistent with the actual phenomena. It is confirmed that the square angle of LC at the end of the electrode is changed suddenly (i.e. the opposite direction of the normal deflection direction of LC), and the mutation angle is −20°, which prone to trace Mura. In addition, four groups of influence factors (total 12 splits) are proposed for physical and simulation verification, and the optimized design scheme of pixel electrode is obtained. The following conclusions are obtained: the inner corner is cancelled, the length of the outer corner is ≥ 3um, and the angle of the outer corner on the right side (which has been referred to in Figure 4, and other pixel directions can be adjusted accordingly) is ≥ 45°, and the turning direction of the left side is in the same direction as the slit or at an acute angle with the slit direction; This scheme can reduce the dark area of the opening area and maximize the transmittance without risk of trace Mura.
In this article uses local brightness compensation to overcome the influence of Nikon exposure mechanism on mura imaging, and verifies the overall design BM line width for different resolutions, ...sizes. The final result is a high‐quality visual effect product, with a reduced defect rate for V‐bend mura on the 14 inch FHD and 16 inch 4K models. Compared to the background value, the brightness difference for L128 is less than 1.5 nits. In addition, combining different BM line widths from 4.7um to 5.5um also achieved the same trend. At present, the verification results have been imported into mass production.
Regulation of the first committed step of peptidoglycan precursor synthesis by MurA‐enzyme homologs has recently taken center stage in many different bacteria. In different low‐GC Gram‐positive ...bacteria, regulation of this step has been shown to be regulated by phosphorylation of homologs of the IreB/ReoM regulatory protein by PASTA‐domain Ser/Thr‐protein kinases. In this issue, Mascari, Little, and Kristich determine this regulatory pathway and its links to resistance to cephalosporin β‐lactam antibiotics in the major human pathogen, Enterococcus faecalis (Efa). Unbiased genetic selections identified MurAA (MurA‐family homolog) as the downstream target of IreB regulation in the absence of the IreK Ser/Thr‐protein kinase. Physiological and biochemical approaches, including determination of MICs to ceftriaxone, Western blotting of MurAA cellular amounts, isotope incorporation into peptidoglycan sacculi, and thermal‐shift binding assays of purified proteins, demonstrated that unphosphorylated IreB, together with proteins MurAB (MurZ‐family homolog), and ReoY(Efa) negatively regulate MurAA stability and cellular amount by the ClpCP protease. Importantly, this paper supports the idea that ceftriaxone stimulates phosphorylation of IreB, which leads to increased cellular MurAA amount and precursor pathway flux required for E. faecalis cephalosporin resistance. Overall, findings in this paper significantly contribute to understanding variations of this central regulatory pathway in other low‐GC Gram‐positive bacteria.
There is a need to establish a novel dataset for the development of
better Mura quantitative evaluation method. Our proposed Mura
simulation and quantitative evaluation (MSQE) dataset consists
of ...Mura simulation images and the corresponding quantitative
evaluation values. For the Mura simulation images, the images
are described in CIE 1931 XYZ space instead of traditional RGB
space to achieve device‐independent on any display panels. For
the quantitative evaluation values, the unique subjective
quantitative evaluation value for each simulation image is
obtained by subjective experiments conducted by different
researchers, different observers, and on different panels, so that
the uncertainty can be minimized by statistical analysis. The
number of samples are growing with more simulation images and
corresponding evaluation values being added into the dataset, so
that more actual Mura patterns can be included into the dataset.
Our proposed MSQE dataset makes it easier to improve the
performance of Mura quantitative evaluation.
Rappresentare la forma della città significa fissare la consistenza fisica di una realtà riferita ad un determinato tempo, tramite percorsi di conoscenza di autori che nel corso dei secoli hanno ...cercato di ricostruire la forma complessa della città, rappresentandola dall’alto, simulando un punto di osservazione senz’altro privilegiato e, per molti secoli, del tutto ideale. Venezia e Parma vengono selezionate per raccontare la storia dell’immagine urbana attraverso autori che hanno registrato graficamente dall’alto, tra gli altri elementi, i limiti di confine tra natura e artificio. Il racconto parallelo e compartivo si articola attraverso la lettura delle piante prospettiche di Jacopo de’ Barbari per Venezia (1500) e di Paolo Ponzoni per Parma (1572). Viene infatti adottata, in questo periodo, una rappresentazione iconografica urbana particolare, la “prospettiva planimetrica”, ricavata da una planimetria eseguita a seguito di un rilievo geometrico, in modo che il perimetro delle mura e la trama viaria apparissero in tutta la loro completezza; gli edifici sono invece raffigurati con la prospettiva, descritta da un punto di vista situato ad altezza variabile sopra l’orizzonte. La crescente attenzione dei cartografi e dei disegnatori nei confronti della città si collega al nuovo tipo di organizzazione statale che considera la città come un’entità funzionale racchiusa all’interno delle mura, la cui vista dall’alto consente di comprenderne la consistenza e le peculiarità.
