Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

open access: yesAdvanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Control of primary productivity and the significance of photosynthetic bacteria in a meromictic kettle lake. [PDF]

open access: yes, 1989
During 1986 planktonic primary production and controlling factors were investigated in a small (A0 = 11.8 · 103 m2, Zmax = 11.5 m) meromictic kettle lake (Mittlerer Buchensee).

GATA4‐Driven Transcription of HtrA1 Promotes Cellular Senescence in Ménière's Disease and Age‐Related Audio‐Vestibular Dysfunction

open access: yesAdvanced Science, EarlyView.
This study identifies the HDAC6/GATA4/HtrA1 axis as a critical driver of cellular senescence in the inner ear. GATA4 nuclear translocation, facilitated by HDAC6 downregulation, transcriptionally activates HtrA1, promoting hair cell senescence, SASP, and audio‐vestibular dysfunction in models of Ménière's disease and age‐related audio‐vestibular ...

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

open access: yesAdvanced Science, EarlyView.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Production of extracellular alkaline protease by new halotolerant alkaliphilic Bacillus sp. NPST-AK15 isolated from hyper saline soda lakes

open access: yesElectronic Journal of Biotechnology, 2015
Background: Alkaline proteases are among the most important classes of industrial hydrolytic enzymes. The industrial demand for alkaline proteases with favorable properties continues to enhance the search for new enzymes.

Anthropologist, heal thyself: Toward an anthropology of healing through relational interbeing

open access: yesFeminist Anthropology, EarlyView.
Abstract I call for an anthropology that confronts its own woundedness. Anthropologists often bear witness to suffering but rarely examine how our own grief, trauma, and institutional distress shape the affective tone of our work. Drawing on fieldwork with Runa (Quechua) women affected by forced sterilization in Peru and guided by my collaborator and ...

Promise‐Keeping Reputations in an Investment Game: An Experimental Investigation

open access: yesInternational Studies of Economics, EarlyView.
ABSTRACT We design a controlled laboratory experiment to mitigate moral hazard problems in livestream shopping when sellers make promises to buyers. In our experiment, the promise‐keeping reputation mechanism allows sellers to send promises to buyers while buyers can observe the sellers' historical promise‐keeping records. Results demonstrate that bare

High Nitrogen and Phosphorus Concentrations in Human-Impacted Soil and Surface Runoff Negatively Affect Water Quality at Momella Lakes, Tanzania

open access: yesLand
Human land use in catchment areas has become a global concern due to its profound effects on water quality degradation. Associated eutrophication and algal bloom outbreaks in aquatic ecosystems pose an increasing threat to species that rely exclusively ...

Nature of chemical composition diversity of the East Ttransbaikalia salt lakes (Russia) [PDF]

open access: yesE3S Web of Conferences, 2019
We have developed a new concept for the formation of geochemical types of salt lakes which explains the nature of their different chemical composition under close landscape-climatic and geological-geochemical conditions.
