A CONSTRUÇÃO DE UM DIREITO POLICIAL: A conexão entre a polícia e a sociedade
Authors: Cordeiro Raphael Joel
Published: October 2023

In Brazil, there is no continuous doctrine of public security that allows for the convergence of legal points regarding the exercise of police activities. Faced with this reality, this article lecture about the need to create Police Law, still unexplored in the brazilian legal system, for the security of the legal security of police activities and for the promotion of the fundamental rights and guarantees of the citizen enshrined in the constitutional text. The research methodology is qualitative, exploratory and descriptive. Thus, without intending to deepen, the study is guided, especially, by Guedes Valente's thesis on the General Theory of Police Law and by Niklas Luhmann's theory of law. Finally, an integrative communication between the social system, the legal system and the police system is proposed for the construction of police legal language which is characterized as a connection between the police and society.

The Information and Communication Technology area of the Military Police of the Federal District has a vital and strategic function for the public security of the Federal District and is inserted in a complex and dynamic environment. Its performance is guided by official documents that consolidate the strategic and tactical planning of this technological area. In this context, this descriptive research aims to verify if there is adequacy of the strategic planning methodology by scenarios in the proposed area, since it is commonly seen as a tactical and not strategic level. For this purpose, official documents guiding the area of Information and Communication Technology of the Military Police of the Federal District will be used. The research is justified by contributing to the development of a theoretical basis to support the studies and their applicability to this important corporate area of the Military Police, as well as the identification of points of improvement in the light of the strategic planning methodology by scenarios, in order to make the less reactive and short-term and more strategic processes. The methodology used was the case study based on document analysis and literature review. The results indicate that the PMDF, considering its area of activity, has a Strategic plan based on prospective scenarios. However, the ICT area does not have a specific strategic plan. The guiding document of the PMDF's ICT is the PDTIC, that is, the ICT Strategy is developed directly in the PDTIC, which is prepared based on the SISP methodology and has a double scope: strategic and directive.

Published: October 2023

Rapid assessments on the outbreak of rice brown planthoppers (BPH) (Nilaparvata lugens Stal) were conducted to investigate the status of BPH populations and the causative factors behind the outbreak. These assessments served as the basis for developing a proper action program. The assessments took place in Banyubiru Sub-District, Semarang District covering four villages (Kebondowo, Rowoboni, Tegaron, Kebumen) in December 2013. We analyzed BPH data, along with information about farmers' practices in managing pests collected through interviews conducted in January 2018 in Indramayu. Additionally, we examined data on the number of BPH-infested areas in Java from 2010 to 2020 and the stock of insecticides in Java in 2021. Simple statistical analyses were carried out. The BPH population had spread throughout Banyubiru and was present in all sampled plots. The average number of BPH eggs ranged from 115.25 to 379.65 per rice hill, while the BPH nymphs and imagoes ranged from 3.42 to 11.87 per rice hill. The relatively low nymphs to imagoes ratio might be influenced by the high BPH predator populations, which ranged from three to six individuals per rice hill. Suspected causes of BPH resistance and resurgence included the application of banned and improper insecticides, as well as the repeated use of the same insecticide active ingredients for an extended period. It is recommended to discontinue the mass spraying of insecticides to prevent further plant damage. In 2022, the Pest Control Movement has suggested replacing chemical insecticides with biological or natural pesticides. Intensive extension programs are strongly needed.
An index formula in a class of groupoid $C^*$-algebras
Authors: Bujukliev Nikolay
Published: October 2023

We consider the groupoid $C^*$-algebra $\mathcal{T} = C^*(\mathcal{G})$, where the groupoid $\mathcal{G}$ is a reduction of a transformation group $\mathcal{G} = (Y \times G)|X$, and $Y$and $X$ are suitable topological spaces. We impose additional constraints on a cross-section $\psi$, which gives opportunity to define cyclic 1-cocycle and to obtain a formula that calculates the index of the Fredholm operators.

This article examines the performance and values of network parameters when applying different algorithms to control network congestion. The Mininet network emulator is used, which creates software-defined networks that give us the opportunity to conduct various experiments with the network and manipulate its parameters. The conclusion is made for the best algorithm to prevent network congestion. An estimate of the relative value of the error was made, which shows that in Mininet deviations in the values can be observed with a larger number of hosts in the network.
Use of gulls rather than terns to evaluate American Mink Mustela vison control.
Authors: Craik J
Published: October 2023

Ratcliffe et al. (2006) compared the breeding biology of terns Sterna spp. on the Uists, Western Isles, where American Mink Mustela vison (hereafter ‘mink’) had been removed, and on nearby Lewis, where there had been no mink control. They showed that hatching success was significantly higher on the Uists, indicating that mink removal improved this aspect of breeding, but found no significant difference in colony productivity between the two areas. The years in which the comparisons were made, 1993 and 2005, were years of low tern productivity, probably caused by poor weather and food shortage, respectively. The authors considered that such factors overrode any effect of mink by killing young terns before mink could take them, and suggested
that any effects of mink would be more detectable in years of high tern productivity when more young terns survived.

The Teacher-Centered and the Student-Centered: A Comparison of Two Approaches
Authors: Ghafar Zanyar Nathir
Published: October 2023

There has been much discussion in the field of education concerning the differences between teaching based on the educator and teaching centered on the student. One of the main points of contention is that teaching should be student-centered. The claim that more student-centered instruction and less focus on the teacher is one of the most contentious aspects of the debate. Every tactic has unique advantages and disadvantages that cannot be had with any other approach. "Teacher-centered instruction" is a term that describes the educational approach that is sometimes referred to as "traditional education" by itself. The stage of learning in which the instructor acts as both the principal figure of authority and the primary source of information for the students enrolled in a particular class. On the other hand, learning focused on the student stimulates students to take an active part in the independent research that they perform by pushing them to concentrate on their requirements. This is because learning centered on the student encourages students to learn about themselves. In this investigation, comparison and contrast of these two approaches have been examined, and an attempt has been made to enumerate the advantages of each potential choice.

In this groundbreaking study, we propose an innovative approach to tackle the formidable task of early detectionand accurate prediction of kidney diseases. By harnessing the potential of a comprehensive healthcare dataset andleveraging a machine learning model originally developed for kidney disease diagnosis, our methodology integratesintelligent feature selection techniques. These techniques, including heuristic based feature selection andevolutionary gravitational search-based feature selection (EGS-FS), allow us to identify the most informative featuresfor accurate prediction. Classification is performed using our newly designed Intelligent Deep Learning basedClassifier, which is further optimized using the cutting-edge Artificial Gorilla Troops Optimizer algorithm. Toassess the performance of our proposed model, we conduct a thorough evaluation and comparison against existingmethods using a range of statistical measures. Remarkably, our experimental results on the widely recognizedChronic Kidney Disease dataset showcase an exceptional accuracy value of 99%. This research not only contributesto the advancement of kidney disease prediction but also provides invaluable insights for efficient patientmanagement. By embracing this novel approach, clinicians can make informed decisions and revolutionize the fieldof kidney disease detection and treatment.

Compared with traditional glass, metallic glass (MG) has excellent properties, such as high strength, high hardness, high fracture toughness, good soft magnetic properties and corrosion resistance due to its unique structure. Such properties enable it to be used in optics, electronics, construction and other fields, making it a highly promising new material with great application potential. As the properties of amorphous alloys are closely linked with their local structures, microstructure characteristics have always been a research focus in the amorphous field. Previous studies show that the onset temperature of heredity and the hereditary fraction of characteristic clusters can be used to effectively evaluate the glass-forming ability. In order to obtain the relationship between the microstructure characteristic and cluster evolution of amorphous alloy, and reveal the formation of glass, the glass transition processes of the Pd82Si18 alloy under different pressure conditions are simulated by using the molecular dynamics method, and the heredity and evolution of the Pd82Si18 amorphous alloy are analyzed by using the cluster-type index method and the reverse tracking method. The simulation results show that the glass transition temperature of the Pd82Si18 alloy can be increased when the pressure is higher, and a large number of icosahedra are formed in the solidified alloy when the pressure is sufficiently high. Icosahedron is a kind of structure that widely exists in amorphous materials and has been studied for quite a long time. In this work, a detailed comparative analysis of two icosahedra is conducted and the heritability of clusters with different chemical compositions under high pressure is studied. The results show that it is easier for icosahedra with central atom Pd and those with central atom Si to form a medium-range order in the Pd82Si18 amorphous alloy. An increase in pressure conduces to the increase of both onset temperature of heredity and hereditary fraction. Combined with the results of cluster heredity analysis at 0 GPa, the Si-centered clusters have stronger heritability than Pd-centered clusters, thus the former ones have a greater influence on the glass-forming ability. These findings are of significance in understanding the relationship between microstructure evolution and glass formation, and also providing certain guidance for designing amorphous alloys.

Introducción. La resistencia de Plasmodium falciparum a diferentes fármacos antipalúdicos es un obstáculo para eliminar la enfermedad. El genotipo resistente de P. falciparum a la artemisinina puede evaluarse examinando los polimorfismos en el dominio de la hélice del gen Pfk13. La Organización Mundial de la Salud recomienda utilizar estas mutaciones como marcadores moleculares para detectar la resistencia a la artemisinina en países donde la malaria por P. falciparum es endémica.Objetivo. Identificar mutaciones relacionadas con la resistencia a artemisinina presentes en el dominio de la hélice del gen k13 de P. falciparum.Materiales y métodos. Mediante la detección pasiva de casos, se recolectaron 51 muestras positivas por microscopía para Plasmodium, provenientes de seis comunidades del distrito de Río Santiago en Condorcanqui, Amazonas. Se realizó la confirmación molecular de la especie mediante PCR en tiempo real y el dominio de la hélice del gen Pfk13 se amplificó y secuenció por electroforesis capilar. Las secuencias obtenidas se compararon con la cepa de referencia 3D7 de fenotipo silvestre.Resultados. Se confirmó un total de 51 muestras positivas para P. falciparum, provenientes de las comunidades de Ayambis, Chapiza, Palometa, Muchinguis, Alianza Progreso y Caterpiza. Después del alineamiento de las secuencias de ADN, se determinó que las muestras no presentaron mutaciones asociadas con resistencia en el gen K13. Discusión. Los resultados obtenidos son coherentes con estudios similares realizados en otros países de Sudamérica, incluyendo Perú. Estos datos proporcionan una línea base para la vigilancia molecular de resistencia a artemisinina en la región Amazonas y refuerzan la eficacia de la terapia combinada con artemisinina en esta área.
El metro de Santiago como mediador socio-espacial entre el sector Oriente y Poniente: el caso de la LÍnea 7
Authors:   , Vergara Browne Sebastián
Published: October 2023

Entre el siglo XX y el presente, la ciudad de Santiago creció considerablemente, su desarrollo urbano vino acompañado de la innovación en sistemas de transporte, políticas de planificación urbana y el crecimiento demográfico. Sin embargo, gran parte del desarrollo de la ciudad, y los usos de suelo, siguen patrones especulativos o capitalistas, tales como el mercado de suelo y las políticas habitacionales, que provocaron cierta polarización en la morfología urbana. Esto determinó la ubicación de las viviendas sociales en la periferia, en contextos con escasos servicios y equipamientos, y de los estratos sociales altos en comunas de oriente. Esto se traduce en una polarización social en la ciudad que, además, afecta al acceso a la ciudad por parte de los habitantes de menos recursos. La infraestructura de transporte urbano ayudó en muchos casos a que se produjera un desequilibrio en el acceso a la ciudad, puesto que gran parte de la trama urbana comprende principalmente la utilización del automóvil, al cual no pueden acceder todos los estratos sociales. Es en este contexto que el transporte público tiene el rol de conectar la ciudad con los habitantes, pero, debido a las grandes distancias y tiempos de traslado, se ha de considerar sistemas de transporte eficientes que conecten a la periferia con el resto de la ciudad. En este sentido la red de metro es el sistema más adecuado para lograr la conexión entre diversas realidades urbanas y para lograr la accesibilidad a servicios y equipamientos para los habitantes periféricos y de bajos recursos. Dicho de otra manera, es una herramienta de integración social urbana. Dentro de la red, se explora a la futura Línea 7 para interpretar su rol como mediador entre realidades urbanas polarizadas por medio de alternativas paliativas de diseño urbano en torno a sus estaciones, puesto que atraviesa casi la totalidad de la ciudad en el sentido Este-Oeste, eje el cual presenta las mayores diferencias sociales y urbanas que se ven exaltadas a medida que se distancian del centro metropolitano. Dicho esto, se estudian las terminales de la línea para determinar nuevas formas de urbanización centradas en el transporte urbano que dialoguen con el crecimiento urbano y el desarrollo sostenible de la metrópolis, entregando el derecho a la ciudad a todos sus habitantes.
Arquitectura, descanso y sueño: diseño de espacios para el descanso de los estudiantes dentro del campus Lo Contador
Authors:   , Muñoz Vildósola Maximiliano
Published: October 2023

Existe una crisis de salud mental a nivel mundial, y dentro de esta crisis mayor existe una crisis subyacente que es la crisis de sueño que afecta multiescalarmente a la población mundial. Esta crisis se ve exacerbada en la población universitaria, debido a diversos factores. Es por esto que es menester hacerse cargo de este problema desde la arquitectura, tanto como desde otras áreas académicas. El diseño de los dormitorios, habitaciones, recámaras, y otros espacios de sueño, siempre ha sido un tema para la arquitectura, debido a la necesidad intrínseca de dormir que tienen las personas. Estos espacios han mutado enormemente a lo largo de la historia, debido a cambios en la sociedad (Público-Privado, por ejemplo) pero también a cambios tecnológicos como la invención del pasillo, las puertas o las camas. La arquitectura ha sido responsable de responder a las necesidades sociales de los espacios de sueño como también ha sido responsable de proponer formas de aumentar el bienestar en el dormir y descansar. En este sentido, la arquitectura del dormir es un espacio cargado políticamente considerando que el dormir en sí es un acto político, por esto al diseñar espacios de sueño, las políticas de sueño del arquitecto se ven plasmadas en el diseño. Se definirán distintas políticas de sueño y con estas sintetizar estrategias de diseño, para diseñar espacios de sueño ad hoc a la época contemporánea. Con estas estrategias se espera diseñar espacios de sueño dentro de universidades que suplan la necesidad de dormir que tienen los estudiantes, académicos, administrativos y funcionarios de las universidades. Estas serán puestas a prueba dentro del campus Lo Contador de la Universidad Católica, utilizando el edificio comedor del campus el cual está vacante debido a un cambio de ubicación del casino.
Espacio overspinning y singularidades en espacios BTZ
Authors:   , Briceño Catalán Matías Sebastián Camilo
Published: October 2023

En esta tesis se estudia el espacio Overspinning, solución a las ecuaciones de Einstein con constante cosmológica negativa (-1/ L^2) en 2+1 dimensiones tal que su momentum angular J sea mayor en módulo a su masa M, esto es, |J |> L |M| . Este espacio-tiempo comparte métrica con el agujero negro BTZ, pero al estar en otro rango de valores de (M,J) no posee horizonte de eventos, dando lugar a una singularidad desnuda. Se encontra su embedding sobre la pseudo esfera definida en R(2,2) al identificar puntos en la superficie. Se integran las ecuaciones de movimiento para sus geodésicas concluyendo que este espacio es geodésicamente incompleto. Con la estructura geodésica se muestra que este espacio es una solución razonable a las ecuaciones de Einstein, con una singularidad quasiregular. Además se estudia la singularidad presente en todos los espacios tipo BTZ a partir de las holonomías que la encierran. Se calculan sus holonomías sobre el espacio tangente ocupando una conexión de SO(2, 1) y luego las holonomías en la teoría de Chern-Simons equivalente ocupando una conexión de SO(2,2). Adicionalmente, se justifica la presencia de una fuente tipo delta de Dirac a partir de la existencia de holonomías no triviales en loops infinitesimales, dando una relación explícita entre estas. Por último, se exponen ideas no exploradas en este trabajo, que serán útiles para futuros trabajos.
Amorphous materials under stresses: understanding critical behavior
Authors:   , Villarroel Cortés Carlos Javier
Published: October 2023

Gran parte de los materiales que utilizamos a diario no se comportan como un sólido elástico o un fluido newtoniano cuando se les aplica deformación. Dentro de la extensa lista de estos materiales que presentan características no lineales en cantidades macroscópicas, podemos encontrar muchos alimentos que consumimos o incluso la piel humana. Comprender estos comportamientos particulares actualmente representa un desafóo importante con aplicaciones en la industria y la medicina. Para responder algunas de las preguntas que estos materiales particulares presentan hoy en día, en esta tesis, utilizando simulaciones numéricas de alto nivel, estudiamos dos fenómenos no lineales críticos, el fenómeno de “Yielding” y el fenómeno de “Strain-Stiffening”. En particular, la transición de “Yielding” se observa en materiales donde, dependiendo de la tensión aplicada, es posible pasar de un estado mecánicamente estable a uno que fluye como un líquido. En este contexto, mediante simulaciones de partículas blandas, se realiza el cálculo de los exponentes críticos que gobiernan el régimen fluido para dos escenarios de esfuerzos aplicados, y se estudia cómo las estadísticas de avalanchas pueden caracterizar el flujo. Finalmente, para el fenómeno “Strain-Stiffening”, se propone un nuevo modelo de redes semi-flexibles capaces de replicar este comportamiento, donde un sistema blando se transforma en uno rígido mediante la aplicación de una deformación. A su vez, este modelo es capaz de explicar y predecir de buena manera los exponentes críticos que gobiernan la transición.

Published: October 2023

In this study, the objective is to analyse the sports participation motives of high school students by gender, age, school type and doing sports regularly. In the research “relational screening model” was used.  770 high school students studying in Malatya participated in the research. In the research, “Sport Participation Motivation Scale” was used.  The scale was delivered to the students over various social media tools through the Google survey application. As a result of the research, it was observed that age, gender, school type and doing sports regularly affect the sports participation motives of the students at different levels. On the other hand, the results of the research revealed that the high school students participated in sports by getting affected from different motives. Furthermore, it was observed that the female students had overcome their fears and concerns about sports participation, and they were willing to make use of sports more to meet their physical, spiritual and social needs. The results of the research also show that regular sports activities have a positive effect on sports participation and the students take this effect for granted

Published: October 2023

A field experiment was conducted on Ridge gourd during rabi season of 2021-22 and 2022-23 at the Experimental Research Plot Soil and Water Engineering, CAE, Raichur. The study aimed to assess the efficacy of a sensor and evapotranspiration based irrigation system in varying irrigation levels, comparing the performance between mulched and non-mulched conditions. The use of sensor-based irrigation at 100% field capacity under mulched has shown positive outcomes, leading to a notable enhancement in crop production by about 9.40% additionally, this approach has resulted in a significant conservation of irrigation water, with savings of approximately 12.35% compared to the treatment involving irrigation at 100% evapotranspiration under mulched, but without the use of sensors. Across the treatments, the water application efficiency ranged from 94.13 to 91.37%. The highest water use efficiency was observed in the treatment with irrigation at 100% FC under mulched condition on pooled basis (0.20 t ha-1 mm-1). The sensor based drip irrigation system under mulched is an economically viable option to be recommended among farmers in arid and semi-arid climate. Despite the higher initial setup costs, farmers can achieve significant cost savings in the long run due to lower water usage, better yields, and minimised labour requirements.

A comprehensive method was developed for determination of tetracycline, oxytetracycline, chlortetracycline, and doxycycline in wastewater. Based on ultra-high performance liquid chromatography coupled with mass spectrometry (UHPLC–MS), the developed method was specific, sensitive, precise, and accurate. Specificity was confirmed with both retention time and accurate m/z value of four antibiotics. Good linearity was achieved for all compounds in the range 5-100 ng/mL. Repeatability of method was proved. The intra-day and inter-day precision were satisfied. The limit of detection and limit of quantification was low enough at several ng/mL. Recoveries were between 95% and 104% at three concentration levels. The concrete sample collected in local swine farm was determined to containing 15 ng/mL oxytetracycline. The developed method provides a reliable and robust tool that can be used for routine analysis of tetracyclines antibiotics in aqueous samples.

Authors: Serojane Rachel , Muma Kangwa I. M. , Mwacalimba Felidah , Mutoloki Elijah
Published: October 2023

Aims: To determine the long-term visual outcome of paediatric cataract surgery performed at Kitwe Teaching Eye Hospital, Zambia.

Study Design:  Cross sectional study.

Place and Duration of Study: Kitwe Teaching Eye Hospital between January 2018 and December 2019.

Methodology: Study population included all children aged between five and fifteen operated on. Participants underwent visual acuity and refraction re-assessment two years post-Operatively. Continuous variables were summarized using the median and interquartile ranges. Stuart-Maxwell test for paired data and Univariate and multivariable logistic regression analysis was used for data analysis.

Results: A total of 117 children participated in the study. About 29% of the children had complications after cataract surgery, and anterior segment complications were the most common experienced complications 18 (15.4%) after surgery. Only one (0.9%) child had visual acuity of (6/18 and better) before surgery while 24 (24.4%) had good visual acuity outcome six weeks after surgery, and at two years after surgery, 41(41.8%) had attained good visual outcome. The visual acuity outcome at six weeks after surgery significantly differed from the visual acuity outcome after two years with the proportion of good visual outcome increasing after two years. Pre-operatively, posterior segment accessibility (AOR 0.13; 95% CI: 0.03 – 0.69), developmental cataracts (AOR 3.09; 95% CI: 1.17 – 8.14) and refraction done at six weeks, were all associated with good visual outcome at two  years after surgery. Poor outcomes were associated with delayed refraction, done after six weeks (AOR 0.22; 95% CI: 0.08 – 0.58), increased number of anterior segment complications (AOR 0.14; 95% CI: 0.03 – 0.72) and posterior segment complications (AOR 0.09; 95% CI: 0.01 – 0.83).

Conclusion: Children's vision significantly improved with time after cataract surgery. Long-term visual outcome follow-up post-surgery is important as it increases the proportion of children attaining good visual outcome after surgery and helps correct uncorrected refractive errors hence optimizing the best visual acuity a child can attain.
TÜRKÇÜ BİR DERGİNİN TARİH ANLAYIŞI: BOZKURT (1939-1942)
Authors: DİNÇER Hasan
Published: October 2023

Türkiye, 1939-1945 yılları arasında yaşanan İkinci Dünya Savaşının dışında kalmıştı. Ancak Almanya’da etkin olan ırkçı ideoloji Türkiye’de taraftar bulmuştu. Reha Oğuz Türkkan’ın yayınlamaya başladığı Bozkurt (1939-1942) dergisinde ırkçı ve Turancı fikirler savunulmaktaydı. Dergide Reha Oğuz Türkkan, Hüseyin Namık Orkun, Nurullah Barıman, Sami Karayel, Nejdet Sançar gibi milliyetçilerin yazıları yayınlanmaktaydı.

Dergide, tarih, savaşlar toplamı olarak kabul edilmiştir. Sanat, sanayi, devlet, sosyal emniyet, intizam, asayiş gibi uygarlık unsurlarını savaşın yarattığı kabul edilmiştir. Türk tarihi, savaşlar ve zaferlerden oluşan bir bütün olarak değerlendirilmişti. Türkleri askeri başarıları, yönetim biçimi, askeri örgütlenme, ekonomik koşullar ile değil, Türk’ün üstün ırk olması ile açıklanmıştı. Osmanlı tarihi, devşirmelerin, ulema etkisiyle, Türkün dışlandığı, ulusal benliğini kaybettiği dönem olarak da değerlendirilmiştir.

Bozkurt dergisindeki tarihe, Türk tarihine savaş ve zafer merkezli bakıldığından, Türklerin uygarlığa katkıları yüzeysel olarak işlenmişti. İkinci Meşrutiyet, Cumhuriyet dönemine pek az değinilmişti. Türkiye’nin Avrupa ülkelerinin gerisinde olduğunu kabul edilirken, İkinci Dünya Savaşı’na katılmaktan yana olmuşlardı. Varılan kanaat odur ki, Bozkurt dergisinde somutlaşan; ırkçı ve Faşist ideolojiyle sarmalanmış, geçmişi tek boyutlu gören, yaşanılan zaman ve toplumsal gerçeklik ile bağı kopmuş bir tarih anlayışıdır.
CUMHURİYETİN İNŞASINDA ATATÜRK’ÜN TAM BAĞIMSIZLIK ANLAYIŞI
Authors: DOĞAN Zafer
Published: October 2023

Bu çalışmada, cumhuriyet tarihimizde Atatürk’ün tam bağımsızlık anlayışını ele almaya; bunu yaparken hem Osmanlı İmparatorluğu döneminden miras kalan bağımlılık zincirlerinin neler olduğunu (millet sistemi, kapitülasyonlar vb…) hem de bunlardan nasıl kurtulduğumuzu anlatmaya çalışacağız. Cumhuriyet döneminde Atatürk’ün izlediği politikanın temel esası bağımsızlık ve diğer devletlerle eşitlik temelinde bir ilişki yürütülmesi üzerine kurulmuştu. Yüzyılların alışkanlıklarıyla Doğu Sorunu’ndaki geleneksel politikalarını sürdürmek isteyen İtilaf devletleri karşısında Türkiye her türlü iktisadi, siyasi ve hukuki ayrıcalığa dayanan eski düzeni reddetmişti. Yeni kurulan devlet sadece ekonomi alanında değil eğitim ve kültür alanlarında da bağımsızlık iddiasına uygun somut politikalar geliştirmişti. Elbette bu tutum çöken imparatorluktan çıkarılan dersler ve tecrübelerle de çok yakından ilgiliydi. Bu bağlamda Cumhuriyetin tam bağımsızlık anlayışının ve kurucu değerlerinin nesnel değerlendirmesinin 100 yıllık cumhuriyet tarihini daha iyi anlamamıza hizmet edeceğine inanıyoruz.

Authors: Sakai Yasuyoshi , Oku Masahide
Published: October 2023

The discovery of microautophagy, the direct engulfment of cytoplasmic material by the lysosome, dates back to 1966 in a morphological study of mammalian cells by Christian de Duve. Since then, studies on microautophagy have shifted toward the elucidation of the physiological significance of the process. However, in contrast to macroautophagy, studies on the molecular mechanisms of microautophagy have been limited. Only recent studies revealed that ATG proteins involved in macroautophagy are also operative in several types of microautophagy and that ESCRT proteins, responsible for the multivesicular body pathway, play a central role in most microautophagy processes. In this review, we summarize our current knowledge on the function of ATG and ESCRT proteins in microautophagy.

The fading affect bias (FAB) refers to the faster fading of unpleasant affect than pleasant affect. The present study investigated various healthy and unhealthy variables as predictors of the FAB across physical symptoms of coronavirus anxiety (PSCA) as well as across events involving and not involving COVID‐19. The data were collected in the heart of the pandemic from April 18, 2020 to January 23, 2021. As expected, social distancing, grit, positive positive and negative affect schedule (PANAS), and rehearsals positively predicted the FAB, whereas negative PANAS, depression, generalized anxiety, and stress negatively predicted the FAB. These results supported the mobilization‐minimization hypothesis, self‐enhancement theories, and the broaden and build theory. Interestingly, PSCA moderated the relations of several variables, such that grit, hypochondria, neuroticism, average daily hours thinking and talking about COVID‐19, negative PANAS, and anxiety predicted the FAB in the expected ways at low PSCA, but all the variables, except negative PANAS and anxiety, positively predicted the FAB at high PSCA. The negative relations between FAB and both negative PANAS and anxiety diminished from low to medium PSCA, and those negative relations remained small at high PSCA. Rehearsal ratings did not mediate the 3‐way interactions. These results emphasize the dramatic effect on emotion regulation, as measured by the FAB, produced by the COVID‐19 pandemic.
Decomposition and composition modeling algorithms for control systems with colored noises
Authors: Xu Ling , Ding Feng
Published: October 2023

This article proposes a novel identification framework for estimating the parameters of the controlled autoregressive autoregressive moving average (CARARMA) models with colored noise. By means of building an auxiliary model and using the hierarchical identification principle, this article investigates a highly‐efficient parameter estimation algorithm. In order to meet the need for identifying the systems with large‐scale parameters, the whole parameters of the CARARMA system is separated into two parameter sets and a decomposition and composition recursive identification algorithm (i.e., hierarchical generalized extended least squares algorithm or decomposition‐based recursive generalized extended least squares algorithm) is presented. Moreover, this article analyzes the convergence of the proposed decomposition and composition recursive identification algorithm. The performance analysis shows that the proposed decomposition and composition identification algorithm can reduce the complexity of the identification algorithm compared with the algorithm without decomposition.

While Ta3N5 shows excellent potential as a semiconductor photoanode for solar water splitting, its performance is hindered by poor charge carrier transport and trapping due to native defects that introduce electronic states deep within its bandgap. Here, it is demonstrated that controlled Ti doping of Ta3N5 can dramatically reduce the concentration of deep‐level defects and enhance its photoelectrochemical performance, yielding a sevenfold increase in photocurrent density and a 300 mV cathodic shift in photocurrent onset potential compared to undoped material. Comprehensive characterization reveals that Ti4+ ions substitute Ta5+ lattice sites, thereby introducing compensating acceptor states, reducing the concentrations of deleterious nitrogen vacancies and reducing Ta3+ states, and thereby suppressing trapping and recombination. Owing to the similar ionic radii of Ti4+ and Ta5+, substitutional doping does not introduce lattice strain or significantly affect the underlying electronic structure of the host semiconductor. Furthermore, Ti can be incorporated without increasing the oxygen donor content, thereby enabling the electrical conductivity to be tuned by over seven orders of magnitude. Thus, Ti doping of Ta3N5 provides a powerful basis for precisely engineering its optoelectronic characteristics and to substantially improve its functional characteristics as an advanced photoelectrode for solar fuels applications.

The sluggish ion transport kinetics and poor interface compatibility are the major challenges for developing high‐performance solid‐state zinc metal batteries. Here, using the densified polyacrylonitrile/silicon dioxide (PAN‐SiO2) nanofiber membrane as a unique multifunctional mediator, a novel mediator‐bridged type of ultrathin (28.6 µm) polymer electrolyte that is rationally designed. The PAN/SiO2 /polyethylene oxide/Zn(OTf)2(PSPZ) polymer electrolyte is demonstrated to significantly enhance multiple kinetics. In addition to superior mechanical properties, the efficient thermal conductive effect endows it with good high‐temperature structural stability. Interestingly, a unique PAN skeleton‐locking‐anion‐enabled fast ion transport mechanism is uncovered to achieve a high Zn2+ migration number (0.71). Moreover, an efficient dendrite‐free Zn deposition guided by a flat dense SEI is demonstrated. In this case, highly reversible Zn metal anodes can be realized in the temperature range extending to −25–80 °C, as well as an impressive 4800 h‐cycle lifespan at the condition of 0.1 mA cm−2. Beyond that, wide‐temperature, high‐rate, durable PSPZ‐based solid‐state Zn/VO2 batteries are also successfully verified. This brand‐new concept of multiple‐kinetics‐enhanced polymer electrolyte design can provide a new perspective for developing all‐climate fast‐charging solid‐state batteries, including but not limited to zinc metal batteries.

Published: October 2023

Graphdiyne (GDY) is regarded as an exceptional candidate to meet the growing demand in many fields due to its rich chemical bonds, highly π‐conjugated structure, uniformly distributed pores, large surface area, and high inhomogeneity of charge distribution. The extensive research efforts bring about a rapid expansion of GDY with a variety of functionalities, which significantly enhance performance including photocatalysis, energy, biomedicine, etc. In this review, the synthetic strategies (in situ and ex situ approaches) that are designed to rationally functionalize GDY, including optimizing their nanostructures by surface/interface engineering with dopants or functional groups (heteroatoms/small molecules/macromolecules), and building up hierarchical GDY‐based heterostructures are highlighted. Theoretical calculations on the structural evolution and electronic characteristics after the functionalization of GDY are briefly discussed. With elaborate functionalization and rational structure engineering, functional GDY applied in a variety of emerging applications (e.g., hydrogen evolution reaction, CO2 reduction reaction, nitrogen reduction reaction, energy storage and conversion, nanophotonics, sensors, biomedical applications, etc.) are comprehensively discussed. Finally, challenges and prospects concerning the future development of GDY‐based nanoarchitectures are also presented.

Published: October 2023

Retrieval studies document Ti‐6Al‐4V selective dissolution within crevices of total hip replacement devices. A gap persists in the fundamental understanding of Ti‐6Al‐4V crevice corrosion in vivo and its impact on local impedance. Previous studies use nearfield electrochemical impedance spectroscopy (nEIS) for characterization of retrieved CoCrMo surfaces and phase angle symmetry‐based EIS (sbEIS) for rapid data acquisition. In this study, these methods are combined with a deep neural network to characterize the local impedance changes after selective dissolution. It is hypothesized that structural changes occurring during dissolution will manifest as property changes to the oxide film capacitance. First, after sustained cathodic activation, the Ti‐6Al‐4V β phase selectively dissolves from the surface. Next, nEIS acquiresn= 100 control andn= 105 dissolved spectra. Over dissolved regions, oxide capacitance significantly increases (Log10Q = ‐4.17 versus ‐4.78 (Scm−2(s)α),p= 0.000). Using single frequency EIS (5000 Hz), a capacitance‐based scanning impedance microscopy method identifies dissolved regions within seconds. Finally, Bode phase plots of the 205 control and dissolved nEIS spectra are input into a deep neural network. After training withn= 180 spectra, the model predicts the surface state forn= 25 previously unseen nEIS spectra with 96% accuracy.

With the growing demand for high‐energy‐density lithium‐ion batteries, Li‐rich Mn‐based layered oxide (LLO) cathodes with high specific capacity and low cost receive significant attention in conventional liquid lithium‐ion batteries. However, LLO is rarely used in sulfide all‐solid‐state lithium batteries (ASSLBs) because of severe interfacial side reactions with sulfide solid electrolytes (SEs), especially at a high operation voltage of 4.8 V (vs Li/Li+). In this work, a dual‐function modification strategy is proposed to enable electrochemically stable LLO in sulfide ASSLBs. The covalent Ru─O bond formed by Ru‐doping can not only stabilize lattice oxygen, preventing further interfacial decomposition involving oxygen, but also enhance the ability of Li diffusion in Li2MnO3 component, and then stimulate the activation of Li2MnO3 phase. Meanwhile, the surface sulfidation strategy establishes a highly stable interface, contributing to the rapid ionic transport at LLO/LPSCl interface. Results show that the modified LLO in sulfide ASSLBs delivers two times higher initial discharge capacity and an extra‐long life of 2022 cycles of up to 4.2 V (vs Li–In) (with >70% capacity retention at 1 C). This research enriches the strategies for improving interfacial compatibility between LLO cathodes and sulfide SEs, thus providing new inspiration for guiding the application of LLO in sulfide ASSLBs.
