DBSCAN is a popular method for clustering multi-dimensional objects. Just as notable as the method’s vast success is the research community’s quest for its efficient computation. The original KDD’96 paper claimed an algorithm with O(n log n) running time, where n is the number of objects. Unfortunately, this is a miss claim; and that algorithm actually requires O(n2) time. There has been a fix in 2D space, where a genuine O(n log n)-time algorithm has been found. Looking for a fix for…

Non-enzymatic glycation is a post-translational modification of proteins that leads to protein crosslinking, aggregation, conformational changes, etc. Chemical reaction of sugars with proteins (Maillard reaction) leads to formation of glycated adducts, known as Advanced Glycation End Products (AGE). HbA1c, the major glycated hemoglobin, increases proportionately with blood glucose concentration in diabetes mellitus. Glycation-induced modification of hemoglobin is a major cause of oxidative…

A new organo-humic fertilizer, produced by accelerated fermentation of poultry manure using the "PEATGEL+" preparation, has a near-neutral reaction, is rich in macro- and microelements, and is free from heavy metals, toxic compounds, and radionuclides. The application of this new organo-humic fertilizer to sandy soil at a rate of 30–45 t/ha has a positive effect on the growth and development of cucumber plants of the "Izyashchny" variety.

Keywords: Poultry Manure;…

Bubble Theory is introduced as a boundary-centric relational framework in which physical systems are modeled as localized, self-maintaining regions (“bubbles”) whose boundaries encode interaction, information flow, and dynamical constraints. A boundary operator B is defined to capture deformation, coupling, and stability, leading to a general dynamical law for bubble evolution and exchange flux between interacting systems. Worked examples—including spherical and toroidal geometries and a…

Recent advancements in the field of loss-of-control recovery and prevention include fault-tolerant control, improved pilot training, and cockpit automation. The benefits of fault-tolerant "intelligent," flight control systems were demonstrated by the Flight Mechanics Action Group on Fault-Tolerant Control of the Group for Aeronautical Research and Technology in Europe. By assessing one of these systems in actual operational scenarios, the research allowed for an improvement in the systems'…

I mean looking for the way to the truth in relation to hearing. The truth can be sought and it should be done. There is a lot of ambiguity in Bekesy's theory [1]. There is new knowledge that Bekesy did not have, there are new research opportunities. Looking through foreign papers, one can believe that faith in Bekesy's theory still reigns. Complex examinations of the basilar membrane are performed. The reason for the lack of a good stapedotomy result is investigated by increasing the piston…

Background/Aim: Previous investigations have showed biological linkages between Periodontal Disease and various types of cancer, such as oral/head and neck cancer, gastric cancer, esophageal cancer, kidney cancer, lung cancer, prostate cancer, hematological malignancies, and cutaneous melanoma. This research investigation aimed to assess the possible association between Periodontal Disease indices and the risk of Cutaneous Melanoma.

The idea of developing a solar hybrid banana dryer designed explicitly for South Pacific will be a significant step forward in addressing both environmental sustainability and economic efficiency in the region. This paper encompasses the design steps and calculations of a sophisticated drying system tailored to meet local conditions, assuming one hybrid dryer as an example. It features an array of components such as solar panels, batteries, solar collectors, an air filter, a heat exchanger,…

Non-Classical Congenital Adrenal Hyperplasia (NCCAH) due to partial 21-hydroxylase deficiency is a frequent and often underdiagnosed cause of hyperandrogenism in women. We report the case of a 39-year-old woman presenting with severe hirsutism. Hormonal evaluation revealed elevated 17-Hydroxyprogesterone (17OHP), confirmed after ACTH stimulation, consistent with NCCAH. Imaging findings were normal. This case highlights the importance of systematic screening for this condition in the…

Ectopic parathyroid adenomas are rare and usually present with biochemical hyperparathyroidism. They most frequently occur in the mediastinum or thymic region. Localization within a lymph node along the recurrent laryngeal nerve chain is extremely rare. We report a case of a 70-year-old woman in whom a non-functioning ectopic parathyroid adenoma was incidentally discovered within a lymph node of the right recurrent laryngeal nerve chain during surgery for a suspicious thyroid nodule.…
