Extending the ALMA Census of Circumstellar Disks in the Upper Scorpius OB Association

open access: yesThe Astrophysical Journal
We present Atacama Large Millimeter/submillimeter Array (ALMA) Band 7 continuum (340 GHz) and carbon monoxide (CO) J = 3–2 observations for an extended sample of disks in the Upper Scorpius OB Association (Upper Sco, age ∼10 Myr).

Soft Artificial Ciliary Brush with Integrated Haptic Feedback for Efficient Airway Mucus Cleaning

open access: yesAdvanced Intelligent Systems, EarlyView.
A fundamental mucus cleaning mechanism is reported, which utilizes both artificial cilia mechanical sweeping and suction‐based mucus cleaning. A novel haptic feedback interface for the artificial cilia provides touch feedback on tissue contact, enhancing operator control and safety.

The Search for Disk Perturbing Planets Around the Asymmetrical Debris Disk System HD 111520 Using REBOUND

open access: yesThe Astrophysical Journal
Debris disks, which are optically thin, dusty disks around main-sequence stars, are often found to have structures and/or asymmetries associated with planet–disk interactions.

Evaluating Isochoric Freezing as a Strategy for Storage of Red Blood Cells

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Red blood cells (RBCs) are needed for life‐saving blood transfusions, but they undergo continuous degradation during storage. Preserving RBCs for clinical transfusion remains a challenge due to storage‐induced damage and limitations of traditional freezing methods.

Microlensing Constraints on the Stellar and Planetary Mass Functions

open access: yesThe Astronomical Journal
The mass function (MF) of isolated objects measured by microlensing consists of both a stellar and a planetary component. We compare the microlensing MFs of A. Gould et al. and T. Sumi et al. to other measurements of the MF. The abundance of brown dwarfs

A Robust Multistep Digestion Method for Microplastics Detection in Human Tissue by MicroRaman Analysis

open access: yesDrug Testing and Analysis, EarlyView.
A unified digestion protocol for human biological samples has been developed for microplastics analysis by microRaman Spectroscopy. ABSTRACT The presence of microplastics (MPs) in human tissues has raised growing concerns, necessitating robust protocols for their reliable extraction and analysis.

A Data-driven Search For Mid-infrared Excesses Among Five Million Main-sequence FGK Stars

open access: yesThe Astronomical Journal
Stellar infrared excesses can indicate various phenomena of interest, from protoplanetary disks to debris disks, or (more speculatively) techno-signatures along the lines of Dyson spheres.

Investigation on hard‐rock breaking performance and auxiliary mechanism of picks assisted with both‐sided high‐pressure water jets

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper investigates the high‐pressure water jet‐pick combined rock‐breaking mode (HPC), which employs high‐pressure water jets to precut grooves on both sides of the picks. The rock‐breaking patterns and performance of the HPC method are obtained, and the auxiliary rock‐breaking mechanism of water jet grooving is revealed.
