Improving binary crow search algorithm for feature selection
Authors: Hamed Alnaish Zakaria A. , Algamal Zakariya Yahya
Published: February 2023

The feature selection (FS) process has an essential effect in solving many problems such as prediction, regression, and classification to get the optimal solution. For solving classification problems, selecting the most relevant features of a dataset leads to better classification accuracy with low training time. In this work, a hybrid binary crow search algorithm (BCSA) based quasi-oppositional (QO) method is proposed as an FS method based on wrapper mode to solve a classification problem. The QO method was employed in tuning the value of flight length in the BCSA which is controlling the ability of the crows to find the optimal solution. To evaluate the performance of the proposed method, four benchmark datasets have been used which are human intestinal absorption, HDAC8 inhibitory activity (IC50), P-glycoproteins, and antimicrobial. Accordingly, the experimental results are discussed and compared against other standard algorithms based on the accuracy rate, the average number of selected features, and running time. The results have proven the robustness of the proposed method relied on the high obtained value of accuracy (84.93–95.92%), G-mean (0.853–0.971%), and average selected features (4.36–11.8) with a relatively low computational time. Moreover, to investigate the effectiveness of the proposed method, Friedman test was used which declared that the performance supremacy of the proposed BCSA-QO with four datasets was very evident against BCSA and CSA by selecting the minimum relevant features and producing the highest accuracy classification rate. The obtained results verify the usefulness of the proposed method (BCSA-QO) in the FS with classification in terms of high classification accuracy, a small number of selected features, and low computational time.
Transient response and performance of prestressed concrete deep T-beams with large web openings under impact loading
Authors: Abbas Rafaa M. , Hussein Lara T.
Published: February 2023

This study reports testing results of the transient response of T-shape concrete deep beams with large openings due to impact loading. Seven concrete deep beams with openings including two ordinary reinforced, four partially prestressed, and one solid ordinary reinforced as a reference beam were fabricated and tested. The effects of prestressing strand position and the intensity of the impact force were investigated. Two values for the opening’s depth relative to the beam cross-section dimensions were inspected under the effect of an impacting mass repeatedly dropped from different heights. The study revealed that the beam’s transient deflection was increased by about 50% with greater amplitudes for response oscillations due to impact loading as the impact force increased twice. The results showed that the transient strains in the reinforcement and concrete increased when increasing the opening depth with higher amplitudes for the response oscillations, whereas it had a minimal effect on the beam’s transient deflection. The reinforcement and concrete strain results indicated a higher damping for the strains as the prestressing strands were introduced. Comparison with solid deep beam response showed remarkable increase in the beam deflection and strains with greater amplitudes for response oscillations when large openings were introduced in the web.

Published: February 2023

Understanding the influence of delamination defects on the damage evolution behavior of carbon-fiber-reinforced polymers (CFRPs) is crucial to improve their engineering applications. This study examined the flexural damage behaviors of CFRP composites by using a combination of acoustic emission (AE) and X-ray micro-computed tomography (micro-CT). Four specimens with different delamination defects and 0.1 wt% cellulose nanofibers (CNFs) were subjected to three-point bending tests. AE was employed to monitor the loading process, and then, micro-CT was utilized to detect the internal damage. The results showed that for the specimens with preset delamination defects near the surface, CNF-reinforced specimen exhibited no obvious enhancement effect on bending strength, and its cumulative acoustic energy decreased by 28% compared with that of CFRP specimens. For the specimen with preset delamination damage in the middle position, CNFs had an obvious enhancement effect on mechanical behavior, and the cumulative acoustic energy decreased by 43%. No obvious kink band was observed in the CNF-reinforced specimens, and during crack propagation, causing cracking and delamination damage was difficult. The results of micro-CT are consistent with those of AE. The results combined the combination of AE and micro-CT reflect the superiority of the hybrid detection system.
San Francisco’s Magnificent Department Stores
Authors: Hitz Anne Evers
Published: February 2023

In the late nineteenth century, San Francisco was booming and its merchant princes built grand stores such as City of Paris, Gump’s, The White House, I. Magnin, and The Emporium in the Union Square area. These stores were integral to the city’s emergence as a world-class commercial hub, starting with the mad scramble for supplies during the gold rush, and its transformation into a tourist mecca in the decades after World War II. This article looks at three of those retail enterprises: City of Paris, which satisfied desires for anything French; the I. Magnin empire, which catered to a selective upper-class clientele; and the Emporium department store, aimed at the middle class with its Bargain Basement and Santa for the kids.

In this study, Cu2NiSnS4 (CNTS) thin films were deposited on glass substrates at different temperatures of 250, 300, 350 400, and 450 ˚C using the chemical pyrolysis technique. The aim of this research was to study the effect of the substrate temperature on the properties of the films. The structural properties of the films were obtained by X-ray diffraction, Raman spectroscopy, and Field Emission Scanning Electron Microscopy (FESEM); the optical properties were determined by the UV-Vis spectroscopy; and the electrical properties were obtained by observing the Hall Effect. The XRD results showed that the CNTS films had a cubic crystalline structure with (111) being the preferred and most common orientation plane. Raman spectroscopy results showed a distinct peak at 336 cm-1 , which indicated a CNTS quaternary compound. The FESEM results demonstrated the presence of nanoparticles with various shapes and sizes. The optical energy band gap was proven to have a value of 1.57-1.82 eV, for the allowed direct transition, and a high absorption coefficient (≥104 cm-1 ) in the visible spectrum region, thereby indicating the potential application of these thin films in solar cells. The Hall Effect measurement on the CNTS thin films indicated a p-type of conductivity for all films, with the highest charge carrier density and mobility occurring at 350C, which makes them ideal for use in photovoltaic applications.

Chalcogenide-based In2Se3 thin films were deposited by RF magnetron sputtering method at room temperature, and then were annealed at different temperature under nitrogen atmosphere in order to study the effect of annealing temperature on structure and optical. X-ray diffraction analysis show that, the preferred orientation in (110), (006), and (207) plane were observed in XRD result of the film sample annealed at 400℃. The Raman spectrometer result reveals that the main Raman peaks were identified as the γ-phase In2Se3 structure and the peak in the film annealed at 400℃ moves to small direction indicates the inner structure changes occurrence. A Spectroscopic Ellipsometer was employed to measure the optical constants including refractive index and the extinction coefficient of the films. The optical bandgap decreased from 3.41 eV to 2.45 eV with the annealed temperature increasing. The variation is attributed to the Burstein-Moss effect.

In this work, the effects of the thin film thicknesses on the structural, optical absorption, energy band gap, dielectric spectra and optical conductivity parameters of the Zinc phthalocyanine thin films are considered. Thin films of ZnPc of thicknesses of 50-600 nm which are coated onto glass substrates are observed to exhibit amorphous nature of growth. The polycrystalline monoclinic ZnPc phase of the films is obtained via annealing the films at 200 oC in a vacuum atmosphere. Increasing the ZnPc films thickness shrunk the energy band gap in the B- and Q- bands and decreased both of the optical conductivities and free holes density in the Q-band. The increase in the film thickness is also observed to decrease the plasmon frequency and the drift mobility of holes in the films. The highest dielectric constant is obtained for films of thicknesses of 100 nm. The annealing process enhanced the optical absorption, redshifts the energy band gap value and the critical energy of the absolute maxima of dielectric constant. In addition, while the heat treatment enhanced both of the scattering times at femtosecond level and the drift mobility, it reduced the free holes density, and the plasmon frequency.

Lipids play a major role in inflammatory diseases by altering inflammatory cell functions, either through their function as energy substrates or as lipid mediators such as oxylipins. Autophagy, a lysosomal degradation pathway that limits inflammation, is known to impact on lipid availability, however, whether this controls inflammation remains unexplored. We found that upon intestinal inflammation visceral adipocytes upregulate autophagy and that adipocyte‐specific loss of the autophagy gene Atg7 exacerbates inflammation. While autophagy decreased lipolytic release of free fatty acids, loss of the major lipolytic enzyme Pnpla2/Atgl in adipocytes did not alter intestinal inflammation, ruling out free fatty acids as anti‐inflammatory energy substrates. Instead, Atg7‐deficient adipose tissues exhibited an oxylipin imbalance, driven through an NRF2‐mediated upregulation of Ephx1. This shift reduced secretion of IL‐10 from adipose tissues, which was dependent on the cytochrome P450‐EPHX pathway, and lowered circulating levels of IL‐10 to exacerbate intestinal inflammation. These results suggest an underappreciated fat‐gut crosstalk through an autophagy‐dependent regulation of anti‐inflammatory oxylipins via the cytochrome P450‐EPHX pathway, indicating a protective effect of adipose tissues for distant inflammation.
Die another day: phytosulfokine at the molecular trade‐off between growth and defense in plants
Authors: Förderer Alexander , Chai Jijie
Published: February 2023

Plants must make decisions to balance their growth versus defense against pathogens. Signaling of the plant peptide hormone phytosulfokine (PSK) has emerged as a critical stimulus for growth promotion. In this issue of The EMBO Journal, Ding et al (2022) show that PSK signaling promotes nitrogen assimilation via phosphorylation of glutamate synthase 2 (GS2). In the absence of PSK signaling, the plants growth is stunted, but its resistance to disease is reinforced.
Reverse electron transfer is activated during aging and contributes to aging and age‐related disease

Published: February 2023

Mechanisms underlying the depletion of NAD+ and accumulation of reactive oxygen species (ROS) in aging and age‐related disorders remain poorly defined. We show that reverse electron transfer (RET) at mitochondrial complex I, which causes increased ROS production and NAD+ to NADH conversion and thus lowered NAD+/NADH ratio, is active during aging. Genetic or pharmacological inhibition of RET decreases ROS production and increases NAD+/NADH ratio, extending the lifespan of normal flies. The lifespan‐extending effect of RET inhibition is dependent on NAD+‐dependent Sirtuin, highlighting the importance of NAD+/NADH rebalance, and on longevity‐associated Foxo and autophagy pathways. RET and RET‐induced ROS and NAD+/NADH ratio changes are prominent in human induced pluripotent stem cell (iPSC) model and fly models of Alzheimer's disease (AD). Genetic or pharmacological inhibition of RET prevents the accumulation of faulty translation products resulting from inadequate ribosome‐mediated quality control, rescues relevant disease phenotypes, and extends the lifespan of Drosophila and mouse AD models. Deregulated RET is therefore a conserved feature of aging, and inhibition of RET may open new therapeutic opportunities in the context of aging and age‐related diseases including AD.
Seed Priming Stimulates Germination and Early Seedling Establishment Of Corethrodendron Multijugum Under Drought Stress
Authors: Li ZhengSheng , Liu Ying
Published: February 2023

Seed priming can alleviate the negative effects of drought stress. The present study focused on exploring the effects of seed priming, drought and their interaction on the germination characteristics of Corethrodendron multijugum. We attempted to standardise an appropriate priming
method for C. multijugum seeds by comparing the effects of various priming methods and drought stress on seed germination and seedling establishment to provide theoretical basis and technical support for subsequent cultivation and production. The results indicated that seed priming,
drought stress and their interaction significantly (P < 0.01) affected all seed germination parameters and seedling establishment parameters, and germination was significantly (P < 0.05) correlated with early seedling establishment under drought stress. Of the different
priming agents used in this study, water, 0.5% KMnO4, 0.3% H2O2and 5% PEG-6000 significantly (P < 0.05) promoted seed germination and seedling establishment in C. multijugum. Among them, 0.5% KMnO4 was the most effective in alleviating
the effects of drought stress on germination and early seedling establishment. Morphologically, the beneficial effects of priming can be attributed to increased seed germination, elongation and biomass accumulation of seedlings.

During the COVID-19 pandemic, social media has become one of the ways to convey information quickly with internet technology. Of the many uses of social media in obtaining information about COVID-19. Of course, not all are accurate. There are many hoaxes or fake news, while on the other hand, the news happened according to the facts. Confirmed cases found in Semarang City were 88,014 cases with a death toll of 4,460 people. This study aims to find out how to receive information about COVID-19 on social media in the community of Semarang City. This study uses an analytic observational study with a cross-sectional design conducted in June-July 2021. The research sample is Semarang residents who have social media with an age range of 15-65 years. The results showed that 68% of respondents believed in information related to COVID-19 on social media. 80% can distinguish hoaxes from true information related to COVID-19 from social media. 71% of respondents confirmed the truth of the news obtained about COVID-19 from Social media. Some respondents believe in the information on social media WhatsApp, Instagram, Facebook, Youtube, Twitter, and Telegram. So growing digital literacy skills are expected to help the government overcome the issue of corona hoaxes and vaccines that are still emerging. The improved critical way of thinking is expected to be the countermeasure.
Dose-dependent response to long-term clomiphene citrate in male functional hypogonadotropic hypogonadism
Authors: Lin Beryl , Twigg Stephen M
Published: February 2023

Functional hypogonadotropic hypogonadism is a relatively common condition in middle-aged to elderly men that can significantly impair quality of life. Besides lifestyle optimisation, androgen replacement remains the mainstay of treatment; however, its adverse effects on spermatogenesis and testicular atrophy are undesirable. Clomiphene citrate is a selective oestrogen receptor modulator that acts centrally to increase endogenous testosterone without affecting fertility. Although it has demonstrated effectiveness in shorter-duration studies, its longer-term outcomes are less well-documented. In this study, we report the case of a 42-year-old male with functional hypogonadotropic hypogonadism who sustained an excellent dose-dependent, titratable clinical and biochemical response to clomiphene citrate with no known adverse effects for 7 years to date. This case highlights that clomiphene citrate has potential as a safe and titratable longer-term treatment option, and the need for further randomised control trials in therapy options to normalise androgen status.

Learning points

Functional hypogonadotropic hypogonadism is a relatively common, but likely underdiagnosed, condition in middle-aged to older males.

Testosterone replacement is the current mainstay of endocrine therapy but can cause sub-fertility and testicular atrophy.

Clomiphene citrate is a serum oestrogen receptor modulator that acts centrally to increase endogenous testosterone production without affecting fertility.

It has potential as a safe and efficacious longer-term treatment option that can be titrated to increase testosterone and relieve clinical symptoms in a dose-dependent manner.

Longitudinal prospective studies as randomised control trials evaluating alternatives to exogenous testosterone are required.

Social perceptions of ecosystem services delivered by coastal wetlands: their value and the threats they face in northwestern Mexico
Authors: Cervantes Escobar Aimée , Ruiz-Luna Arturo , Berlanga Robles César Alejandro
Published: February 2023

Wetlands are recognized for their socio-environmental value and capacity to provide ecosystem services (ES) that are currently threatened by diverse drivers, including those derived from climate change. These changes in the ES delivery may not be recognized by their users, and to determine the extent to which communities are aware of the presence and importance of coastal wetlands, participatory workshops were held in four coastal communities in northwestern Mexico following the Metaplan methodology. The effects produced by extreme rainfall events (as a manifestation of climate change) on wetlands and their ES, were also analyzed. Four coastal wetlands (estuaries, saltmarshes, mangroves, and lagoons) were among the most important ecosystems, while poor fishing practices, mangrove deforestation, and pollution, were identified as their main threats. Climate change, land use changes and water mismanagement, also threat wetlands. There were a few differences among communities, mostly related to the number of ES and their categories; nonetheless, saltmarshes and mangroves were priority wetlands in the communities included in this study, recognizing the ES they provide. Most of the participants in all communities coincided on the main threats and pressures facing wetlands and their ES, particularly those related to climate change, which also affect their livelihoods. But, despite the awareness, regional coastal wetlands continue to decline, considering that participatory processes are necessary for establishing the importance of wetlands while incorporating traditional knowledge, alternative actions, and novel solutions into management actions that may be scaled from the community level into regional development strategies.

Published: February 2023

The bone ring technique is applied for vertical augmentation, in which the dental implant and autogenous block bone graft are simultaneously inserted. We investigated the healing of bone around implants placed simultaneously using the bone ring technique with and without membrane placement after a 12-month healing period. Vertical bone defects were created on both sides of the mandible of Beagle dogs. Implants were inserted into the defects through bone rings and fixed with membrane screws as healing caps. The augmented sites on one side of the mandible were covered with a collagen membrane. Samples were harvested 12 months after implantation and assessed histologically and by microcomputed tomography analysis. All implants remained throughout the healing period; however, except for 1 implant, they showed lost caps and/or exposure to the oral cavity. The implants had contact with newly formed bone despite frequent bone resorption. The surrounding bone appeared mature. The medians of bone volume and percentages of total bone area and bone-to-implant contact within the bone ring were slightly higher in the group with membrane placement than in that without membrane placement. Nevertheless, none of the evaluated parameters were significantly affected by the membrane placement. In the present model, soft tissue complication was frequent, and the membrane application did not reveal the effect at 12 months after implant placement using the bone ring technique. Sustained osseointegration and maturation of surrounding bone were observed in both groups after a 12-month healing period.
The Use of a Coded Healing Abutment in the Restoration of a Single, Immediately Placed Implant in the Esthetic Zone: A Clinical Case Report
Authors: Attar Esraa A.
Published: February 2023

For several years, the implant-level impression procedure started by removal of the healing abutment, followed by connection of the impression coping to the implant. Encode Complete (Encode, Biomet 3i, Biomet 3i, Palm Beach Gardens, FL) was introduced to eliminate implant-level impressions by offering a healing abutment-level impression protocol. This report illustrated the treatment of a single tooth in the anterior esthetic zone using Encode Complete. A 23-year-old female patient reported to the prosthodontics clinic complaining of a fractured maxillary anterior tooth that was deemed nonrestorable. After immediate implant placement, soft tissue preservation and temporization of the implant, healing abutment level impression was made. The codes embedded on the occlusal surface communicated the implant depth, hex-orientation, platform diameter, and interface. The definitive Encode gold-plated titanium abutment was anatomically designed virtually with customized margin, contour, taper, and emergence profile. The milling process was initiated, and the virtual design data were sent to the Robocast Center for analog placement in the original Encode master cast. The definitive abutment was placed on the master cast using Robocast technology, followed by the fabrication of the final porcelain fused to zirconia cement-retained all ceramic crown. The abutment was secured to the implant with a Gold-Tite abutment screw, followed by the final cement-retained implant crown placement. Recall visits were obtained at 1 week, 1 month, 3 months, and 1 year after final prosthesis insertion.
Higher-order turbulence around simple and complex piers using particle image velocimetry

Published: February 2023

The objective of this study was to explore the higher-order turbulence statistics of flow and turbulent length scales around a complex pier (CP) and compare the results with those for a simple pier (SP). The velocity data were recorded in a laboratory flume using particle image velocimetry (PIV). The PIV data were analysed to estimate the velocity fluctuations of third order, turbulence production and dissipation rates, turbulent length scales and the contributions of burst–sweep events to the total Reynolds shear stress around the piers mounted on a rigid flat surface. The skewness and advection coefficients indicated a more asymmetric distribution of velocity fluctuations for the SP than for the CP. Ejection and sweep events illustrated the dominance of similar strengths for an extended period, downstream of the piers. The upstream turbulent kinetic energy production was similar for both piers, while the upstream dissipation rate was higher for the CP. The length scales were greater at the upstream for the case of the SP while, downstream, they were greater for the CP. The findings of this work demonstrate the importance of a pile cap in restricting downward-moving flow by showing a lower magnitude of scour-inducing turbulence parameters for the CP as compared with the SP.

Теория воплощенного познания предполагает укоренение абстрактных, в том числе эмоциональных, концептов в сенсомоторном взаимодействии с физической средой. Так, верхняя область пространства ассоциируется с положительными переживаниями, а нижняя — с отрицательными. Взаимодействие между различными доменами репрезентаций выражается в том числе в эффекте кросс-модального соответствия — фасилитации восприятия в одной модальности конгруэнтными аспектами стимулов в другой. Нами была впервые предпринята попытка вызвать данный эффект с помощью аудиальных стимулов различной высоты и вербальных стимулов, обозначающих эмоциональные состояния и имеющих соответствующие пространственные коннотации. В основной части исследования приняли участие 36 добровольцев, которым в ходе эксперимента одновременно предъявлялись аудиальные (тональные посылки 1000 и 2000 Гц) и вербальные (слова, различающиеся по эмоциональной валентности и соотносимые с различными частями пространственного поля) стимулы. Задача респондентов заключалась в идентификации высоты (низкая/высокая) предъявленного тона. Анализ различий во времени реакции с помощью линейных смешанных моделей показал наличие статистически значимых различий между конгруэнтным (например, эмоционально положительное слово — высокий тон) и неконгруэнтным, а также конгруэнтным и контрольным условиями. Помимо этого было оценено наличие эффекта кросс-модального соответствия для каждого стимульного слова и для обоих звуков по отдельности, что показало его наибольшую выраженность для высокого тона и для части вербальных стимулов. Таким образом, был обнаружен эффект кросс-модального соответствия, возникающий при когнитивной обработке стимулов разной модальности, осуществляемой за счет механизмов разного уровня сложности: от перцептивного анализа аудиальных сигналов до выделения семантики лексических единиц, обозначающих абстрактные идеи. Отдельным результатом работы стало создание базы данных вербальных стимулов с заданными эмоциональными и пространственными параметрами, которые могут быть использованы в широком круге психо- и нейролингвистических исследований.
EMP 18S Illumina Amplicon Protocol v2
Authors: A. Amaral-Zettler Linda
Published: February 2023

The 18S protocol detailed here is designed to amplify eukaryotes broadly with a focus on microbial eukaryotic lineages. The primers target the 18S SSU rRNA and are based on those of Amaral-Zettler et al. (2009). The constructs are designed to be used with the Illumina platform. For running these libraries on the MiSeq and HiSeq, please make sure you read the supplementary methods of Caporaso et al. (2012). You will need to make your sample more complex by adding 5-10% PhiX to your run. The outlines of the protocol are the same as the 16S protocol, but different primers, PCR conditions, and sequencing primers are used. In addition, we have designed a blocking primer that reduces the amplification of vertebrate host DNA to be used on host-associated samples, especially those that have a low eukaryotic biomass. Blocking primer strategy is based on Vestheim et al. (2008).

The peculiarities of the formation of military women‟s images in Ukraine and the People's Republic of China (PRC) had been examined in the article. The Armed Forces of Ukraine and the People's Liberation Army of China are in the process of rapid modernization. The beginning of a full-scale war against Ukraine and China's significant influence on the future of world politics brought military issues into focus. Available or free access Internet Media space of Ukraine and China with assistance of search engines Google and Baidu had been analysed in the study. According to modern geopolitical situation in the world, period of study of two years before full-scaled Russian invasion in Ukraine had been chosen. Images, as well as texts, are sources of information about various aspects of social and cultural phenomena. Their analysis requires mastery of a complex of methodological and interpretive practices. We considered images of military women as a product of social construction and carriers of cultural semantics. The authors of the article, using the supplemented and expanded scheme of photo analysis by P. Shtompka, investigated the norms, rituals, customs, values and lifestyle of military women of Ukraine and the People's Republic of China shown on photos. In addition to comparing images of female military personnel in the armies of the People's Republic of China and Ukraine, the study compared images of men and women and military women and women of other professions (in the same Internet publications). The detection of gender stereotypes, faceism in advertising and publications for women is a popular topic in the world and domestic scientific discourse. The images we have studied largely contrast military women with stereotypical images of female consumers. Typical forms of visual representation of women in the army through illustrations in Internet publications had been highlighted. The main formats are: parade photos, "difficult army everyday life", "achievements and military career". Involvement of women in the security forces requires images of idealized fighters. In the analysed images of Chinese publications, this idealization contains elements of ageism and sexualization, in particular in advertising and poster and parade scenes. The colours deserve special attention in the ceremonial photos. Differences were found in the depiction of the beauty of military women in Ukrainian and Chinese media. It was concluded that the distribution of images of military women in Internet publications can be a practice of gender egalitarianism.

Immersive technology has provided many benefits in various fields, including in medical education. Several learning obstacles have been overcome, such as limited practicum space, few teaching aids, and limited time. To address this issue further, the authors are building virtualized AR and VR modules that are implemented to help users improve their skills before doing practical work in the real world. The authors use AR technology to study human anatomy, while VR technology to study Normal Childbirth Surgery. To build a module, the authors need to design an interface that can provide convenience for the user, so that it can be used continuously. This research collected feedback from users to build an unobtrusive interface when running the application and remove animations that have nothing to do with the medical lab module. The authors designed the interface with a Meta-UI approach to provide a clean look, so users can focus on doing practicums. This research observed that the use of Meta-UI in this study has given satisfaction to the users through the analysis of the PIECES framework. The authors got a score between 3.97 - 4.20 for AR and 4.5 - 4.67 for VR from the user satisfaction measurement which means that users are satisfied with the offerings and services of this app.

In this work, the sharp focusing of a laser beam whose initial polarization pattern is formed by superposition of a cylindrical mth-order vector beam and a homogeneous linearly polarized beam is considered theoretically and numerically. Although in the source plane of such a beam both the angular spin momentum and the third Stokes parameter are equal to zero, we reveal that given odd m, subwavelength local regions are formed in the focal plane, where transverse vortex energy flows occur and the third Stokes parameter (the on-axis component of the angular spin momentum) is non-zero. Thus, at odd m, at the focus of such a beam there are – sub-regions with elliptical polarization of light with alternating handedness in the adjacent sub-regions (clockwise and counterclockwise). This phenomenon can be interpreted as a variant of an optical Hall effect. We note that at even m, the field at the focus is linearly polarized at every point and no transverse energy flow is observed.
„Music To Be Murdered By” – (nie)znane melodie i inne (pop)kulturowe elementy Bowiego w Warszawie Doroty Masłowskiej w perspektywie krytyki feministycznej
Authors: Sadowska Martyna
Published: February 2023

Główne cele artykułu to: (1) próba uchwycenia, zdefiniowania i zinterpretowania relacji popkultury i krytyki feministycznej w Bowiem w Warszawie Doroty Małowskiej, (2) analiza sposobów realizacji modelów genderowych w kulturze popularnej, tu zwłaszcza na podstawie piosenek bigbitowych zawartych w dramacie, i (3) refleksja nad możliwym oporem względem opresyjnych schematów tożsamościowych zaprezentowanych w dramacie Masłowskiej. Ponadto w kontekście Bowiego w Warszawie refleksji poddaje się dwa pojęcia: „znanych” (hegemonicznych) oraz „zwariowanych” (subwersywnych) melodii (looney tunes). Artykuł podkreśla też dwoisty stosunek Masłowskiej do „popkultury” w perspektywie krytyki feministycznej.
Zbrojna napaść Rosji na Ukrainę a kwestia odpowiedzialności karnej jednostki
Authors: Czeszejko-Sochacka Katarzyna
Published: February 2023

Zbrojna napaść Rosji na Ukrainę zapoczątkowała dyskusję o możliwości postawienia w stan oskarżenia osób odpowiedzialnych za popełnienie zbrodni międzynarodowych w tym konflikcie. Celem artykułu jest analiza przepisów Rzymskiego Statutu MTK pod kątem ewentualnego ich oskarżenia. W rozważaniach udzielono odpowiedzi na pytanie, jakie czyny mogłyby zostać przypisane żołnierzom rosyjskim biorącym udział w inwazji na Ukrainę. Przedstawiono także możliwość pociągnięcia do odpowiedzialności karnej prezydenta Federacji Rosyjskiej i zwrócono uwagę, że pełnienie funkcji głowy państwa nie wyłącza jego indywidualnej odpowiedzialności. Zauważono też, że działania wojsk rosyjskich w Ukrainie są bardzo zbliżone do metod, jakimi posługiwali się serbscy żołnierze w czasie wojny w Bośni i Hercegowinie.
