Moduli Spaces and Target Space Duality Symmetries in $(0,2)\; Z_N$ Orbifold Theories with Continuous Wilson Lines [PDF]

, 1994
We present the coset structure of the untwisted moduli space of heterotic $(0,2) \; Z_N$ orbifold compactifications with continuous Wilson lines. For the cases where the internal 6-torus $T_6$ is given by the direct sum $T_4 \oplus T_2$, we explicitly ...

Deficiency of SCAMP5 Triggers Pancreatic β‐Cell Secretory Dysfunction and Apoptosis

Advanced Science, EarlyView.
This study demonstrates that hyperglycemia in diabetes activates ChREBP, which epigenetically represses SCAMP5 expression in pancreatic β‐cells. This SCAMP5 deficiency impairs insulin secretion by downregulating the calcium channel CaV1.2. Furthermore, reduced SCAMP5 triggers β‐cell apoptosis by stabilizing VDAC1 and enhancing its interaction with Bax,

Turkey red prints: identification of lead chromate, Prussian blue and logwood on Turkey red calico

Conservar Património, 2019
In this research, printed Turkey red calico from the 19th century is analysed using conservation-based techniques to identify the materials used in their manufacture. Turkey red production was a significant industry in Scotland, and the textiles found in

A Hexadecacationic Metal–Organic Cage for Anchoring Sulfonates: High‐Order Binding of Di‐ and Trisulfonates and High‐Performance Removal of Perfluorosulfonates from Water

Advanced Science, EarlyView.
Developing synthetic hosts that can bind sulfonate anions or sequester perfluorosulfonates is crucial in biological and environmental sciences. Here, a Zr‐based metal–organic cage (1) integrating electron‐deficient tripyridinium panels is designed and synthesized.

Optical Fiber‐Based Versatile Wearable Force Myography System: Application to Human–Robot Interaction

Advanced Intelligent Systems, EarlyView.
A compact and flexible wearable force myography sensor based on optical fiber technology detects muscle activity through pressure‐induced light loss. The sensor offers high sensitivity for detecting subtle force and finger motion changes, along with excellent signal stability under dynamic and sweating conditions.

Fire Histories and Rainforest Aboriginal Archaeology in the Wet Tropics Bioregion, North Queensland

Archaeology in Oceania, EarlyView.
ABSTRACT Unlike the dominant Australian savanna‐sclerophyll vegetation, tropical rainforests do not burn easily. Any evidence of fire in Australian rainforests therefore invites explanations of its source. Analysis of 187 radiocarbon dates that include selected charcoal fragments from 23 soil pits and 7 archaeological sites from the Wet Tropics ...

Does It Pay to Be Green? A Total Quality Perspective

Business Strategy and the Environment, EarlyView.
ABSTRACT The question of whether, when, and how efforts for better corporate environmental performance (CEP) improve corporate financial performance (CFP) remains controversial. We revisit this question from a total quality perspective, which unites previous research and highlights interdependencies between mediators of the CEP–CFP relationship.

Functional Analysis of Histidine‐Dependent Self‐Cleaving RNAs Obtained by In Vitro Selection

ChemBioChem, EarlyView.
Ribozymes can be nucleic acid medicines given their catalytic activity. We attempted to obtain functional RNAs that mimic ribonuclease A catalytic mechanisms. Functional RNAs with high histidine specificity were obtained, suggesting that histidine acts in active structure formation.

Determine the Elemental Composition of Minerals From Complex Solid‐Solution Series by Raman Spectroscopy: Implications for Mars Exploration Missions

Journal of Raman Spectroscopy, EarlyView.
This study presents a hierarchical Raman‐based classification model for determining the elemental composition of garnets within complex solid‐solution systems. The workflow combines spectral preprocessing, dimensionality reduction, and two‐level classification: first distinguishing between pyralspite and ugrandite groups, and then classifying ...
