Mscl-X: Meta Supervised Contrastive Learning With Gaussian Prototypes For Robust Few-Shot Open-Set Modulation Classification, Emmanuel Mawuli Agbator

Theses and Dissertations

Automatic modulation recognition has found its way into the core modern-day wireless communication systems whereby intelligent receivers estimate signal formats without any prior coordination with the transmitters. Challenging situations arise in any working radio frequency environment for the conventional modulation recognition systems due to insufficient labeled data, rapidly fluctuating channel conditions, and appearance of plenty other unseen modulation types. Taken together, these challenges raise questions concerning the ability to institute learning frameworks that could perform well on few-shot and open-set conditions. Hence the thesis attempts to address the same by proposing two complementary learning-based frameworks for few-shot open-set modulation recognition …

The performances of the models were evaluated with the goodness-of-fit criteria. XGBoost showed a performance of …

Hatchability And Nestling Viability In An Extremely Short-Beaked Pigeon Breed, Türker Savaş, Hakan Erdem, Cemi̇l Tölü

Turkish Journal of Veterinary & Animal Sciences

The selection of hobby animals for breeding by enthusiasts is often based on aesthetic considerations, which can have a negative impact on the animals’ biology. Furthermore, “extreme traits” that deviate from ancestral norms, such as short beaks in pigeons, can be detrimental to the animal’s welfare. Beaks perform many essential functions, such as facilitating feed intake and eggshell breaking. The present study investigates possible hatching problems and the nestling viability of short-beak pigeons through a study of the breeding records of Mısıri (short beak), Baska (medium beak), and Turkish Dönek (normal beak) pigeons, as well as data from one breeding …

The methodology employs various machine learning algorithms on music represented by audio features such as Mel-frequency cepstral coefficients and Mel spectrograms. Spectral analysis using Uniform Manifold Approximation and Projection (UMAP) offers novel insights into music representation learning. The …

The Regulatory Framework For Crowdsourced Online Dispute Resolution: Revisiting The Dispute Resolution Triangle, Yun Zhao, Zhiming Xiao

Pepperdine Dispute Resolution Law Journal

Crowdsourced Online Dispute Resolution (CODR) constitutes a transformative approach to digital-era disputes, fundamentally reconceptualizing dispute resolution through distributed participant networks rather than merely digitizing traditional alternative dispute resolution. Anchored in Katsh and Rifkin’s dispute resolution triangle (trust, convenience, expertise) and Perritt’s co-regulatory governance model, this paper analyzes CODR’s evolution from early systems such as iCourthouse to contemporary implementations. Case studies of eBay Community Court (contractual self-regulation prioritizing convenience) and Xianyu Small Court (state-aligned hybrid governance optimizing expertise through algorithmic juror specialization) demonstrate how platforms operationalize these theoretical frameworks. The legal analysis examines jurisdictional fragmentation and enforcement challenges, revealing how regulatory …

Muste, George Markakis, Michael Millstein, Sheldon Oberfeld, Allen Roth, Jack Shao, Thomas L. Steinemann, Elisa Bala, Sunil K. Srivastava, Priya Shukla, Jeffrey Chu, Xinyu Gu, Delaney Ryan, Daniel F. Martin, Jeffrey M. Goshe

Journal of Academic Ophthalmology

Background: Presurgical training during ophthalmology residency is crucial for a successful transition to cataract surgery in the operating room. Growing evidence suggests that residents benefit more from supervised hands-on learning than from independent practice. The supervised presurgical curriculum approach for early resident cataract surgical training has not been widely studied, especially with regard to the steepest part of the learning curve.

Purpose: To investigate the impact of a formal presurgical wet lab curriculum on early resident cataract complication rates, operative time, and patient visual outcomes.

Methods: In this retrospective case-control study, resident primary cataract cases before and …

Microbiome-Responsive Hydrogels: From Biological Cues To Smart Biomaterials, Rajesh Vadlapatla, Amir Nasrolahi Shirazi, Ajoy Koomer, Judy Weng, Matthew Ernest Ghilarducci, Alai Qudus, Keykavous Parang

Pharmacy Faculty Articles and Research

Background: Stimuli-responsive hydrogels (SRHs) are smart polymeric materials that undergo reversible physicochemical changes in response to abiotic cues and externally applied fields, enabling applications in drug delivery, wound healing, and tissue engineering. However, they exhibit limited biological specificity and do not adequately reflect the dynamic, disease-relevant complexity of native tissue microenvironments. Microbe-colonized tissues display distinctive biochemical features driven, shaped by microbial metabolism, including localized pH gradients, short-chain fatty acid production, secretion of quorum-sensing molecules, biofilm formation, and expression of specialized enzymes. These endogenous, spatiotemporally regulated signals are closely linked to host physiology and pathology but remain underutilized in hydrogel …

Inventory Control Model On Matrix Geometric Method For Intermittently Obtainable Server With Balking And Feedback In Markovian Queueing Model, Indumathi P, Kathikeyan K

Baghdad Science Journal

The paper deals with the problem of queueing-inventory system that has uncertain service conditions, and it discusses the contribution of server availability and customer behaviours like balking and feedback that are also added in to the system performance. In real life service and production situations, servers are not always available because of maintenance processes, capacity constraints, or other unforeseen disruptions. In order to simulate such characteristics, the system is modelled in a Markovian context where the interdependency between inventory levels, customer inflows, and server capacity is simulated. The time of customer arrivals is random and the time to serve is …
