Whispering gallery modes in semiconductor optical fibres and optical bottle microresonators
We explore the optical properties of whispering gallery modes (WGMs) in silicon optical fibres and optical bottle microresonators. In particular, a pump-probe technique is used to experimentally demonstrate thermally induced all-optical modulation.

Photochemical fluorescence activation in arrays of microspherical containers
Responsive Materials, EarlyView.Photoresponsive microdroplets can be produced with precise structural control from organic solutions of a photoactivatable fluorophore and aqueous solutions of a surfactant at a microfluidic cross junction. These dye‐doped microspheres assemble spontaneously in close‐packed arrays in aqueous media.

Cutting freedom down to size Liberté calibrée
Journal of the Royal Anthropological Institute, EarlyView.Freedom, as a concept and a value, presents limited prospects for anthropological comparison. The study of enslavement, much neglected in attempts to develop an anthropology of freedom, shows that freedom has been imagined by the enslaved as the opposite of their condition only under particular circumstances.

Observation of Whispering-Gallery Modes in a Diamond Microsphere
IEEE Photonics Technology Letters, 2018 We demonstrate a Type Ib diamond (nitrogen impurity of >5 ppm) microsphere whispering-gallery mode resonator in the near-infrared wavelengths between 1426.10 nm and 1427.42 nm in the 90° elastic-light-scattering for both transverse magnetic (TM) and transverse electric (TE) polarizations.

SlideSAVR: Enabling Live Analysis during Data Presentations via Multimodal Sketching and Voice Input
Computer Graphics Forum, EarlyView.Abstract Interpersonal communication in data science can yield sought‐after insights, but presentation environments are often not conducive for live analysis, forcing the process to move offline. Through a formative survey with 16 participants, we identified both technical (e.g., complexity of tools) and psychological (e.g., pressure of programming ...

Whispering-Gallery Mode Resonators for Detecting Cancer [PDF]
Sensors, 2017 Optical resonators are sensors well known for their high sensitivity and fast response time. These sensors have a wide range of applications, including in the biomedical fields, and cancer detection is one such promising application. Sensor diagnosis currently has many limitations, such as being expensive, highly invasive, and time-consuming.

Whispering gallery modes for elastic waves in disk resonators
AIP Advances, 2011 The resonant modes of elastic waves in disk resonators are computationally studied with the finite difference time domain method. Different materials examined for the disk such as platinum and silicon.

Turning to lines: Writing with multiplicity of exilic memories
Anthropology and Humanism, Volume 51, Issue 2, December 2026.Abstract In this flash tip on writing, I suggest drawing and sketching as techniques that allow ethnographers to work through emotionally charged stories when words alone fall short. I share a vignette from my ethnographic research with Iranian newcomer women in Canada, who are living an exilic life and carrying embodied memories of protests both here (

Anthropology and Humanism, Volume 51, Issue 2, December 2026.Abstract During fieldwork, anthropologists engage in emotional, social and economic exchanges with interlocutors, through which to better understand one's own positionality and that of others. When such exchanges occur with an interlocutor who becomes a romantic lover, these exchanges are filtered through desire, amplifying their psychological ...

Nanophotonics, Volume 15, Issue 20, 27 October 2026.Mitochondrial oxidative metabolism generates ROS. Downstream chemiexcitation triplet carbonyls, singlet oxygen; produces ultra‐weak photon emission (UPE). Energetic bounds restrict well‐coupled respiration to extremely weak, red/NIR‐biased emission. Stronger visible UPE indicates elevated oxidative flux, linking measured photon counts to redox state ...
