A Remark on Dilaton Stabilization [PDF]

open access: yes, 1997
Dilaton stabilization may occur in a theory based on a single asymptotically free gauge group with matter due to an interplay between quantum modification of the moduli space and tree-level superpotential. We present a toy model where such a mechanism is

The Modification Mechanism of Nano-Liquids on Streamer Morphology and Breakdown Strength under Microsecond Pulse

open access: yesApplied Sciences, 2020
In liquid mediums, whether the breakdown strength can be greatly improved after introducing the nano-particles has been widely investigated, however, there has been no scientific consensus on the modification mechanism of this anomalous phenomenon.

REOB/SBS Composite-Modified Bitumen Preparation and Modification Mechanism Analysis

open access: yesBuildings, 2023
To investigate the effect of recycled engine oil bottoms (REOB) as a compatibilizer on the properties of styrene–butadiene–styrene-modified bitumen (SBS-PMB), this paper studied the preparation method, properties, and micro-mechanism of composite ...

Fivebrane Gravitational Anomalies [PDF]

open access: yes, 1999
Freed, Harvey, Minasian and Moore have proposed a mechanism to cancel the gravitational anomaly of the M-theory fivebrane coming from diffeomorphisms acting on the normal bundle.

Complex Modification Orders Alleviate the Gelling Weakening Behavior of High Microbial Transglutaminase (MTGase)-Catalyzed Fish Gelatin: Gelling and Structural Analysis

open access: yesFoods, 2023
In this paper, the effects of different modification orders of microbial transglutaminase (MTGase) and contents of pectin (0.1–0.5%, w/v) on the gelling and structural properties of fish gelatin (FG) and the modification mechanism were studied.

Strictly strategy-proof auctions

open access: yes, 2020
A strictly strategy-proof mechanism is one that asks agents to use strictly dominant strategies. In the canonical one-dimensional mechanism design setting with private values, we show that strict strategy-proofness is equivalent to strict monotonicity ...

Improved IEEE 802.11 point coordination function considering fiber-delay difference in distributed antenna systems [PDF]

open access: yes, 2014
In this paper, we present an improved IEEE 802.11 wireless local-area network (WLAN) medium access control (MAC) mechanism for simulcast radio-over-fiber-based distributed antenna systems where multiple remote antenna units (RAUs) are connected to one ...

Experimental study of dispersive clay modified by calcium lignosulfonate

open access: yesRock and Soil Mechanics, 2021
Dispersive clay is a type of water-sensitive soil, which has the characteristics of dispersivity and material loss when encountering water. The influential factors and modification mechanism of dispersive clay modified by calcium lignosulfonate (CL ...

Fading mechanism on grain refinement and modification with Al-B-Sr master alloys in an aluminium-silicon cast alloy [PDF]

open access: yesArchives of Metallurgy and Materials, 2022
A fading mechanism during casting of treated Al-B-Sr master alloys in an aluminium-silicon cast alloy was investigated. Two different master alloys, the Al-3%B-3%Sr and Al-4%B-1%Sr were demonstrated for the efficiency test both grain refinement and ...
