Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

Advanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

Nonreciprocal Swarmalators With Reconfigurable and Controllable Formations for Robot Collectives

Advanced Robotics Research, EarlyView.
Nonreciprocal swarmalator interactions are enabled through control barrier functions to transform self‐organizing robot collectives into reconfigurable, constraint‐aware systems. Complex two‐ and three‐dimensional shapes, continuous morphing, obstacle‐aware navigation, collective splitting, and object transport emerge from modulating agent‐level ...

Deep Contrastive Learning for High‐Throughput Prediction of Drug Resistance Mutations from Sequences

Advanced Science, EarlyView.
This study presents DeepMutDTA, a deep learning framework aimed at predicting mutation‐induced changes in protein‐drug interactions and prioritizing variants potentially linked to drug resistance. Trained on large‐scale data, it incorporates SimSiam‐MuTF, a label‐aware contrastive fine‐tuning strategy that encourages separation between WT and MT ...

Intravital Multimodal Imaging of Human Cortical Organoid Transplantation in a Mouse Model of Chronic Stroke

Advanced Science, EarlyView.
A multimodal intravital imaging platform enables longitudinal tracking of human cortical organoids transplanted into chronic stroke lesions. By combining surgical microscopy, MRI, bioluminescence imaging, and two‐photon fluorescence microscopy, the platform captures graft placement, viability dynamics, and cellular‐scale morphology in vivo, offering a ...

Positive surgical margins in cancer of the larynx

European Archives of Oto-Rhino-Laryngology, 2001
In order to determine what should be done for laryngeal cancer patients when surgical margins are positive, and to evaluate their prognosis, a retrospective review of 21 laryngeal cancer patients with positive surgical margins out of 714 surgically treated cases (2.9%) was carried out. Nineteen patients were treated with postoperative radiation therapy.

Positive Surgical Margins After Nephron-Sparing Surgery

European Urology, 2012
Little is known on the natural history of positive surgical margins (PSMs) in partial nephrectomy (PN). Accumulating data suggest that secondary nephrectomy might not be necessary in all patients with PSMs after PN.Provide an overview on incidence and risk factors for PSMs after partial nephrectomy and on the rate of local and distant disease ...

Positive Surgical Margins: Race or Surgeon?

European Urology, 2015
The present study by Jalloh et al. published in this month’s issue of European Urology aimed to investigate the influence of racial variations on pathologic outcome after radical prostatectomy (RP) for low-risk prostate cancer (PCa) patients. The positive surgical margin (PSM) rate was significantly higher in the African American group (31%) than in ...

[Positive surgical margins after radical prostatectomy].

Urologia, 2014
Positive surgical margins (PSMs) in radical prostatectomy specimens are usually considered a negative prognostic parameter. However, their definition and the management of patients with PSMs remain unclear. The aim of the present review is to define pathological features of PSMs,to report their incidence and risk factors and to update PSMs prognostic ...

Radical prostatectomy: Positive surgical margins matter

Urologic Oncology: Seminars and Original Investigations, 2013
A positive surgical margin (PSM) in the radical prostatectomy (RP) specimen is associated with biochemical recurrence (BCR) and the need for adjuvant radiation therapy, and is a surrogate for surgical quality. We review the available data describing the identification, anatomy, and management of PSM after RP.A PubMed search (using English language as a

The significance of “positive” margins in surgically resected epidermoid carcinomas

Head & Neck Surgery, 1978
AbstractSixty‐two patients with epidermoid carcinomas of the head and neck (excluding glottic larynx and skin), in whom surgical‐resection margins were classified as “positive,” were studied to determine the incidence of local recurrence, the subsequent clinical course, and survival.
