Physics Reach of High-Energy and High-Statistics IceCube Atmospheric Neutrino Data
This paper investigates the physics reach of the IceCube neutrino detector
when it will have collected a data set of order one million atmospheric
neutrinos with energies in the 0.1 \sim 10^4 TeV range. The paper consists of
three parts. We first demonstrate how to simulate the detector performance
using relatively simple analytic methods. Because of the high energies of the
neutrinos, their oscillations, propagation in the Earth and regeneration due to
\tau decay must be treated in a coherent way. We set up the formalism to do
this and discuss the implications. In a final section we apply the methods
developed to evaluate the potential of IceCube to study new physics beyond
neutrino oscillations. Not surprisingly, because of the increased energy and
statistics over present experiments, existing bounds on violations of the
equivalence principle and of Lorentz invariance can be improved by over two
orders of magnitude. The methods developed can be readily applied to other
non-conventional physics associated with neutrinos.Comment: 21 pages, 7 figures, Revtex

Oil and gas potential of Ukrainian sector of the Sea of Azov by a comprehensive assessment of aerospace research data
One of the lines of optimization of prediction and exploration of oil and gas fields in the offshore area is involvement of new unconventional data sources, in particular materials of multispectral satellite imagery. A rating assessment of oil-and-gas promising areas in the Ukrainian sector of the Sea of Azov was carried out, taking into account the results obtained in determining the rank of OGPA according to the structural and
geomorphological, neotectonic, spectral and brightness, and structural and geological criteria
Characteristics of immune-active and immune-silent phenotypes of early-stage cervical carcinoma as revealed by transcriptome sequencing
Molecular classification, immuneheterogeneity, and the existence of distinct immunophenotypes of virus-associated cervical cancer (CeCa) remain as-yet weakly explored issues, and this is particularly true of its earliest clinical stages and pre-invasive forms: cervical intraepithelial neoplastic (CIN) lesions. The goal of the study was to identify transcriptomic landscapes of invasive CeCa at its initial progression that differ substantially in their immune-related characteristics, patterns of signaling pathways and composition of the microenvironment. Transcriptome profiling was carried out using RNA-sequencing on Illumina platform. A panel of surgical-derived tissue samples comprised human papillomavirus-positive CIN grade 1-3, cancer of FIGO IA1-IIB stages, and morphologically normal epithelium. Transcriptomic profiles were analyzed with the use of bioinformatics tools, such as gene set enrichment (GAGE) for signaling pathways, xCell enrichment for cell composition identification, and PREDA positional analysis of genomic data. Hierarchical clustering revealed heterogeneity of transcriptomic profiles within the early-stage CeCa, namely, the existence of two clusters of tumor samples and three functional patterns of genes showing coordinately altered expression. Pathway enrichment analysis on genes differently expressed between the two clusters/groups of CeCa samples (‘A' and ‘B') and CIN (group ‘C') suggested that invasive tumor progression in groups ‘A' and ‘B' might rely on immunologically dissimilar mechanisms. xCell analysis confirmed heterogeneity of changes in the abundancies of cell populations when comparing CeCa sample groups and CIN, along with differences in immune and stromal scores. PREDA demonstrated that these transcriptomic differences could be linked to different chromosomal regions and co-localized with particular gene families and potentially the reported virus integration hotspots. Overall, the existence and detectability of different transcriptomic immune-based phenotypes of invasive CeCa at its initial stages of progression is shown, which may provide new options to broaden the knowledge and applicability of target and immune anti-cancer therapy
High-pressure behavior of superconducting boron-doped diamond
This work investigates the high-pressure structure of freestanding
superconducting ( = 4.3\,K) boron doped diamond (BDD) and how it affects
the electronic and vibrational properties using Raman spectroscopy and x-ray
diffraction in the 0-30\,GPa range. High-pressure Raman scattering experiments
revealed an abrupt change in the linear pressure coefficients and the grain
boundary components undergo an irreversible phase change at 14\,GPa. We show
that the blue shift in the pressure-dependent vibrational modes correlates with
the negative pressure coefficient of in BDD. The analysis of x-ray
diffraction data determines the equation of state of the BDD film, revealing a
high bulk modulus of =51028\,GPa. The comparative analysis of
high-pressure data clarified that the sp carbons in the grain boundaries
transform into hexagonal diamond.Comment: 7 pages, 4 figure
Особливості викладання фізики у медичному коледжі
Одним із базових предметів, що входять до переліку дисциплін, необхідних для отримання повної загальної середньої освіти, є курс фізики, теми якого розглядаються у 10-11-х класах. У загальному розумінні ця наука розглядає все те, що оточує людину протягом всього життя. Для студента медичного коледжу розуміння основних закономірностей та взаємозв’язків у фізичних процесах чи явищах є особливо важливим.
Зазвичай на перших заняттях викладач наголошує на важливості та всеосяжності даної дисципліни, формуванні наукового світогляду, розвитку логічного мислення тощо. Але в медичних навчальних закладах, в першу чергу, слід пояснювати, що не лише оточуючій світ існує за законами фізики, але і сама людина є фізичним об’єктом, біологічною системою. Саме в людському організмі яскраво представлені усі розділи науки від механіки до ядерної фізики. Вивчати динаміку на прикладі опорно-рухового апарату, розглядати тиск чи капілярні явища на колах кровообігу, будувати зображення в збірній лінзі, перевіряючи результат власним оком – все це робить опанування дисципліни набагато цікавішим, у результаті чого зростає не лише інтерес до науки, але і розуміння перебігу тих чи інших процесів та явищ
