Spontaneous Emergence of Run-and-Tumble-Like Dynamics in a Robotic Analog of \textit{Chlamydomonas}: Experiment and Theory Open
Run-and-tumble (RT) motion is commonly observed in flagellated microswimmers, arising from synchronous and asynchronous flagellar beating. One such example is a biflagellated alga, called \textit{Chlamydomonas reinhardtii}. Its flagellar s…
Depletion effect in an active chiral system Open
In a confined two-dimensional geometry shaken vertically, spinning rings immersed in spherical beads exhibit long-range, depletion-like entropic interactions—forming dimers at high bead concentration and repelling at low concentration.
Data Analysis and Artificial Intelligence in The Marine Sector Open
This paper investigates the revolutionary influence of data analysis and artificial intelligence (AI) in the maritime sector, with a focus on cargo handling, ship route planning, and fuel efficiency optimisation. By integrating modern data…
Uncovering Universal Characteristics of Homing Paths using Foraging Robots Open
Homing–the incredible ability of animals to navigate back to their homes from unfamiliar places is surprisingly widespread and crucial for their survival. However, the physical understanding of this phenomenon is not yet developed. Here we…

Bulk condensation by an active interface Open
We present experiments, supported by mechanically detailed simulations, establishing bulk vapor-liquid condensation of a hard-bead fluid by a tiny population of orientable motile grains that self-assembles into a moving polarized monolayer…
Phases and correlations in active nematic granular systems Open
A novel phase characterised by a periodic ordering profile in a vibrated granular system of apolar rods is reported.
An insight into high-temperature deformation mechanism of magnesium in-situ composite through development of Johnson-Cook and constitutive model Open
The establishment of deformation mechanisms of Mg-metal matrix composite (Mg-MMC) is important to improve the high-temperature challenging applications. In this present work, an AZ91/TiC + TiB2 hybrid in-situ Mg-MMC was synthesized, and it…
Abstracts Criticare - IJCCM2023 Open
CRITICARE -IJCCM2023and 50 years, who presented with complaints of abdominal pain, vomiting, and decreased urination to the Emergency Department.After taking history, all of them confirmed to have intake of fish gallbladder within the last…
Programming tunable active dynamics in a self-propelled robot Open
We present a scheme for producing tunable active dynamics in a self-propelled robotic device. The robot moves using the differential drive mechanism where two wheels can vary their instantaneous velocities independently. These velocities a…
Properties of the dissipation functions for passive and active systems Open
The dissipation function for a system is defined as the natural logarithm of the ratio between probabilities of a trajectory and its time-reversed trajectory, and its probability distribution follows a well-known relation called the fluctu…
A comprehensive review on the effect of process parameters and post-process treatments on microstructure and mechanical properties of selective laser melting of AlSi10Mg Open
Selective Laser Melting (SLM) process has a great potential to create unique 3D components of AlSi10Mg with exceptional degrees of freedom for wide range of applications in industries. However, the presence of porosity and other defects in…
Active nonreciprocal attraction between motile particles in an elastic medium Open
We show from experiments and simulations on vibration-activated granular matter that self-propelled polar rods in an elastic medium on a substrate turn and move towards each other. We account for this effective attraction through a coarse-…

A Critical Review on Effect of Process Parameters on Mechanical and Microstructural Properties of Powder-Bed Fusion Additive Manufacturing of SS316L Open
Additive manufacturing (AM) is one of the recently studied research areas, due to its ability to eliminate different subtractive manufacturing limitations, such as difficultly in fabricating complex parts, material wastage, and numbers of …
Segmentation and Classification of Beatboxing Acoustic Voice Tract Variations in MRI through Image Processing Technique Open
Human beatboxing is a vocal art making use of speech organs to produce vocal drum sounds and imitate musical instruments. Beatbox sound classification is a current challenge that can be used for automatic database annotation and music-info…
Phases and excitations of active rod–bead mixtures: simulations and experiments Open
We present large-scale simulations, supplemented by experiments, on flocking, banding and broken-symmetry excitations in a monolayer of polar rods and spherical beads, confined between horizontal plates and rendered active by vertical vibr…
Trapping and sorting active particles: Motility-induced condensation and smectic defects Open
We present an experimental realization of the collective trapping phase transition [Kaiser et al., Phys. Rev. Lett. 108, 268307 (2012)PRLTAO0031-900710.1103/PhysRevLett.108.268307], using motile polar granular rods in the presence of a V-s…

Stability of the interface of an isotropic active fluid Open
We study the linear stability of an isotropic active fluid in three different geometries: a film of active fluid on a rigid substrate, a cylindrical thread of fluid, and a spherical fluid droplet.
Plastic Sample Cutting System Open
The goal of this project was to provide Winpak with a solution to cut two different sizes of samples; 8 in x 10 in and 10 cm x 10 cm rectangles for samples of up to 600 microns in thickness. The solution provided would primarily need to be…
Enhancement of Microorganism Swimming Speed in Active Matter Open
We study a swimming undulating sheet in the isotropic phase of an active nematic liquid crystal. Activity changes the effective shear viscosity, reducing it to zero at a critical value of activity. Expanding in the sheet amplitude, we find…
