Authors: Silaban Rico Kurniawan , Putra Leonardus Sandy Ade , Tjahjamooniarsih Neilcy
Published: February 2024

This research aims to analyze Quality of Service (QoS) parameters on cellular networks using four providers by measuring throughput, packet loss, delay and jitter parameters when conducting Video Streaming and Online Games using the Wireshark application. The research method involves direct measurement of QoS parameters in several strategic locations in Punggur Kecil village, data was taken at three different location points with a distance comparison of ±500 meters. From all the recapitulations of QoS parameter measurement results, it can be concluded that the value of each QoS parameter can vary for each package which includes the categories poor, medium, good and very good because the bandwidth received by each provider is different. The cause of high and low values of different QoS parameters, Throughput is caused by the number of packet arrivals measured during the observation process, Packet Loss is caused by the number of queues exceeding capacity, Delay is caused by low Throughput values and the number of packets sent, while the Jitter value is influenced by the Delay value. The results obtained are that the Indosat provider is the recommended provider when carrying out Video Streaming and Online Games, because the Quality of Service value produced is superior to other providers. The average values of the Throughput, Packet Loss, Delay and Jitter parameters at each location for the Indosat provider are respectively 796kbps, 2.63%, 22.6ms and 22.6ms. Provider XL is 708kbps, 1.67%, 12.6ms, and 12.6ms. Provider Telkomsel 667kbps, 0.33%. 55.9ms, and 56ms. As well as the Smartfren provider 50kbps, 0.38%, 102.6ms, and 102.7ms.

Published: February 2024

UAV (Unmanned Aerial Vehicle), also commonly called drone, is a flying robot technology that can be controlled remotely and can also fly autonomously based on the mission given by the operator. Drones are usually used for various purposes such as package delivery, watering plants, land mapping, natural disaster monitoring, photography, videography and others. Drones have many types, one of which is a drone with four motors as the main drive, commonly called a quadcopter drone. Quadcopter drones have evolved a lot based on current needs. Although quadcopter drones have many uses, the development of quadcopter drone research in Indonesia is quite slow, one of the quadcopter drone components whose development is quite slow is the flight controller. Flight controller (FC) is a main controller brain in drones that has complex functions in quadcopter drone control. The function of the FC is to regulate motor speed, stabilize and maintain altitude. In this research, FC is designed to control the stability of quadcopter drones while flying. This FC was developed by applying LoRa technology as an internal receiver. LoRa technology is used to receive control data from the remote control (RC) and simultaneously send sensor data. The purpose of this research is to design FC to improve local products in the field of technology and participate in the development of flying robot technology, especially on quadcopter drones and to determine the performance of LoRa technology after being integrated as an internal transceiver in FC for remote control of quadcopter drones.

Urinary Tract Infections (UTIs) are widespread globally, with a notably higher incidence in women. In 2018, the European Medicines Agency (EMA) endorsed the use of fluoroquinolones for uncomplicated UTI treatment. Following this recommendation, several international agencies adopted similar guidelines. Consequently, older antimicrobial agents like fosfomycin emerged as primary treatment options for UTIs. In this context, our study aimed to evaluate the susceptibility of Escherichia coli strains from urine samples to various recommended UTI antibiotics. These strains were collected between January 2017 and July 2020 in São Paulo, Brazil. We utilized the disk-diffusion method for antimicrobial susceptibility testing, interpreting the results according to BRCAST/EUCAST guidelines. Out of the 86,957 urine cultures undertaken during this timeframe, 10,041 yielded E. coli isolates. Of these, 8,655 were tested against fosfomycin, with 99.0% (8,572 strains) found to be susceptible. Additionally, susceptibility rates for other drugs were as follows: nitrofurantoin (95.8%), amoxicillin/clavulanic acid (83.9%), ciprofloxacin (65.1%), norfloxacin (65.6%), and levofloxacin (67.7%). Notably, of the 571 ESBL-positive strains, 94.0% were susceptible to fosfomycin. It’s important to mention a slight decline in fosfomycin susceptibility observed during this period. This finding underscores the importance of continuous monitoring for fosfomycin resistance and rational usage of the drug.

Published: February 2024

Treatment of Ziegler-Natta (ZN) catalysts with BCl3 improves their activity by increasing the number of active sites. Here we show how 47/49Ti solid-state nuclear magnetic resonance (NMR) spectroscopy enables to understand the electronic structure of the Ti surface sites present in such ZN pre-catalysts, prior to activation with alkyl aluminium. High-field (21.1 T) and low temperature (~100 K) NMR augmented by DFT modelling on the pre-catalyst and corresponding molecular analogues enables the detection of 47/49Ti NMR signatures and a molecular level understanding of the electronic structure of Ti surface sites. The associate Ti surface sites exhibit 49Ti NMR signatures (δiso, exp = –170 ppm / CQ, exp = 9.3 MHz / κ = 0.05) corresponding to well-defined fully chlorinat-ed hexacoordinated Ti sites adsorbed on a distorted surface of the MgCl2 support, formed upon post-treatment with BCl3 and re-moval of the alkoxo ligands, paralleling with the increased polymerization activity.

Narrowband emissive multiresonant thermally activated delayed fluorescence (MR-TADF) emit-ters are a promising solution to achieve the current industry targeted color standard, BT.2020, for blue color without using optical filters, aiming for high efficiency organic light-emitting di-odes (OLEDs). However, their long triplet lifetimes, largely affected by their slow reverse inter-system crossing rates, adversely affect device stability. In this study, a helical MR-TADF emitter (f-DOABNA) has been designed and synthesized. Because of its -delocalized structure, f-DOABNA possesses a small singlet-triplet gap, EST, and displays simultaneously an exception-ally faster reverse intersystem crossing rate constant, kRISC, of up to 2 × 106 s1 and a very high photoluminescence quantum yield, PL, of over 90% in both solution and doped films. The OLED with f-DOABNA as the emitter achieved a narrow deep-blue emission at 445 nm (full width at half-maximum of 24 nm) associated with CIE coordinates of 0.150, 0.041, and showed a high maximum external quantum efficiency, EQEmax, of ~20%.
Toward GHz-Photodetection with Transition Metal Dichalcogenides
Authors: Strauss Fabian , Zeng Zhouxiaosong , Braun Kai , Scheele Marcus
Published: February 2024

Transition metal dichalcogenides (TMDCs) exhibit favorable properties for optical communication in the GHz regime, such as large mobilities, high extinction coefficients and silicon compatibility. While impressive improvements of their sensitivity have been realized, the bandwidths of these devices have been mostly limited to few MHz. We argue that this shortcoming originates in the relatively large RC constants of TMDC-based photodetectors, which suffer from high surface defect densities, inefficient charge carrier injection at the electrode/TMDC interface and long charging times. However, we show in a series of papers that rather simple adjustments in the device architecture afford TMDC-based photodetectors with bandwidths of several 100s MHz. We rationalize the success of these adjustments in terms of the specific physical-chemical properties of TMDCs, namely their anisotropic in-plane/out-of-plane carrier behavior, large optical absorption, and chalcogenide-dependent surface chemistry. Just one surprisingly simple yet effective pathway to fast TMDC photodetection is the reduction of the photoresistance by using light-focusing optics, which enables bandwidths of 0.23 GHz with an energy consumption of only 27 fJ/bit. By reflecting on the ultrafast intrinsic photoresponse times of few picoseconds in TMDC heterostructures, we motivate the application of more demanding chemical strategies to exploit such ultrafast intrinsic properties for true GHz-operation in real devices. A key aspect in this regard is the management of surface defects, which we discuss in terms of its dependence on the layer thickness, its tunability by molecular adlayers and the prospects of replacing thermally evaporated metal contacts by laser-printed electrodes fabricated with inks of metalloid clusters. We highlight the benefits of combining TMDCs with graphene to heterostructures that exhibit the ultrafast photoresponse and large spectral range of Dirac materials with the low dark current and high responsivities of semiconductors. We introduce the bulk photovoltaic effect in TMDC-based materials with broken inversion symmetry as well as a combination of TMDCs with plasmonic nanostructures as means for increasing the bandwidth and responsivity simultaneously. Finally, we describe the prospects of embedding TMDC photodetectors into optical cavities with the objective of tuning the lifetime of the photoexcited state and increasing the carrier mobility in the photoactive layer. The findings and concepts detailed in this account demonstrate that GHz photodetection with TMDCs is feasible, and we hope that these bright prospects for their application as next-generation optoelectronic material motivates more chemists and material scientists to actively pursue the development of the more complicated material combinations outlined here.

Targeting therapeutic agents to the brain to treat the central nervous system (CNS) diseases is a major challenge due to the blood-brain-barrier (BBB). In this study, an attempt was made to deliver a model drug such as doxorubicin (DOX) to the brain in a mice model through DOX-Polysorbate 80 (DOX-PS80) conjugates. DOX was successfully conjugated with the non-ionic surfactant Polysorbate 80 (PS80) by carbamate linkage and the conjugate was characterized by different spectroscopic techniques such as FTIR, UV-Visible and NMR. The DOX conjugation efficacy was found to be 43.69 ± 4.72 %. The in vitro cumulative release of DOX from the conjugates was found to be 4.9 ± 0.8 % in PBS of pH 7.3 and 3.9 ± 0.6 % in simulated cerebrospinal fluid (CSF) of pH 7.3 at the end of 10 days. In vitro BBB permeability assay was carried out using bEnd.3 cells and DOX-PS80 conjugate showed a 3-fold increase in BBB permeability compared to controls. In vitro cytotoxicity assay using U251 human glioblastoma cells showed an IC50 value of 38.10 µg/mL for DOX-PS80. Cell uptake studies revealed that DOX-PS80 was effectively taken up (90%) by the bEnd.3 and U251 cells and localized in cytoplasm at the end of 24 h. Tumor spheroid assay and in vivo experiments in Swiss albino mice demonstrated the possibility of DOX-PS80 conjugate crossing the BBB and delivering the drug molecules to the target site for treating CNS disorders.

Automation of electrochemical measurements can accelerate the discovery of new electroactive materials. One of the hurdles to automated electrochemical measurement is the pretreatment of electrodes because mechanical polishing is usually conducted manually. Here we investigate the automation of electrochemical measurements using a robotic arm. We demonstrate automated mechanical polishing using a polishing station with a moving polishing pad and evaluate the effect of different polishing motions. Our automatic polishing method improved the corroded electrodes, and we found the effect of polishing motions was not significant. This research is a step toward automating electrochemistry experiments without human intervention.
Desymmetrization of Diboron (4) by a Trifluorination B-Masking Strategy: Practical Synthesis of Unsymmetrical Diboron Species
Authors: Eghbarieh Nadim , Masarwa Ahmad
Published: February 2024

Herein, we report a straightforward practical and simple method for efficiently synthesizing a BF3- containing unsymmetrical diboron salts. This method involves the direct desymmetrization of commercially available diboron (4). This desymmetrization is based on a selective B-masking strategy via nucleophilic trifluorination, providing the elusive diborons bearing a trifluoroborate group. The synthetic utility of these salts is demonstrated through various examples of (sequen-tial) B-ligand interconversions, enabling the synthesis of unsymmetrical diboron derivatives. These products, which serve as valuable building blocks, are obtained in high yields.
Voces del sentido desde la espesura del yo
Authors: Holzapfel Cristóbal
Published: February 2024

Entre tantas posibles concepciones del ser humano – desde el acento en lo sagrado en las culturas ancestrales, la razón socrática, la fe de la teología cristiana, la centralidad cartesiana, la finitud de Kant, la acción de Fichte, la voluntad de Schopenhauer o Nietzsche, la singularidad de Kierkegaard, la posibilidad y proyección de Jaspers o Heidegger, el homo ludens de Huizinga, el ser persona de Scheler, la carencia de Gehlen, y otras – lo entendemos aquí como buscador de sentido. Y como cualquier buscador, explorador o aventurero (al modo de Ulises) anhelamos conquistar, poseer el sentido, lo que, por cierto, nunca logramos concluir. Pues bien, en esa afanosa búsqueda hay voces que vienen de “alicientes del sentido”, a saber, en primer lugar, del sentir, recordar, imaginar, querer, introduciendo la razón, a través del pensar, el concepto universal que pretende no sólo darle una dirección a todo lo anterior, sino incluso dominar aquellas “voces del sentido”. Mas, sobre la razón está el yo, el cual es ante todo conciencia, la cual a su vez está frecuentemente acechada por el espíritu dionisiaco o expuesta a la imposición del espíritu apolíneo. Y aun se suma a todo ello la conciencia en su dimensión ética. ¿Cómo logra entonces el yo, sumido en su propia espesura, escuchar, dominar y orientar estas voces?

Model predictive control of a serial link robot manipulator
Authors: Srinivasan A.
Published: February 2024

This paper presents a novel approach for model predictive control dynamics applied to a two-link manipulator robot. The technique involves the initial step of linearizing the inherently nonlinear dynamic model of the robot through the application of feedback linearization control. Once the linear model is derived, a predictive control strategy is developed to enhance the robot's overall performance. To achieve this, we introduce a quadratic criterion, and the associated parameters are meticulously computed to induce specific behaviors within the closed-loop system. The primary objective of this study is to effectively control the arm robot, guiding it from an initial configuration to a desired final configuration by employing the predictive control approach, all while minimizing the quadratic criterion. The chosen criterion serves as a crucial metric in evaluating the system's response and optimizing its behavior during the control process. To validate the effectiveness of the proposed method, a series of simulation results are provided, showcasing the system's performance under various conditions. These simulations serve as empirical evidence supporting the feasibility and efficiency of the introduced model predictive control approach for the dynamics of a twolink manipulator robot. The outcomes highlight the method's potential for real-world applications and contribute to the ongoing advancement of control strategies in robotic systems.

Authors: Khan Anindita , Roy Jibendu Sekhar
Published: February 2024

To improve radio access capability, sky connections relying on satellites or unmanned aerial vehicles (UAV), as well as high-altitude platforms (HAP) will be exploited in 6G wireless communication systems, complementing terrestrial networks. For long-distance communication, a large smart antenna will be used that is characterized by high amounts of power consumed by digital beamformers. This paper focuses on reducing power consumption by relying on a thinned smart antenna (TSA). The performance of TSA is investigated in the sub-6 GHz band. The differential evolution (DE) algorithm is used to optimize excitation weights of the individual dipoles in the antenna array and these excitation weights are then used in TSA for beamforming, with signal processing algorithms deployed. The DE technique is used with the least mean square, recursive least square and sample matrix inversion algorithms. The proposed method offers almost the same directivity, simultaneously ensuring lower side lobes (SLL) and reduced power consumption. For a TSA of 20, 31, and 64 dipoles, the power savings are 20%, 19.4%, and 17.2%, respectively. SLL reductions achieved, in turn, vary from 5.2 dB to 8.1 dB.

Los (auto)postergados inicios literarios de Ángel Guinda como clave hermenéutica para descifrar su obra lírica
Authors: Gracia Gaspar Luis
Published: February 2024

Tras el fallecimiento del poeta español Ángel Guinda (1948-2022), la atención a su obra lírica se halla en sostenido auge. Pero esta creciente recepción enfrenta una contrariedad crucial: el cercenamiento de la producción temprana de la mano del mismo autor, hecho nada baladí en tanto que el estudio de estos postergados o autopostergados inicios literarios se erige como una clave crítica determinante para descifrar su obra lírica. El presente artículo sitúa el foco sobre esos albores poéticos, ahondando en lo ventajoso de este prisma hermenéutico específico y la propia poesía del vate. Se pretende así aportar una base teorética a propósito de dicha óptica, en relación con el significativo nexo entre la vida y obra de Guinda y los distintivos de sus versos entre la década de los setenta y noventa del siglo xx.

“Three Quarks for Muster Mark!” A Slavic gloss to Joyce’s 'Finnegans Wake'
Authors: Witczak Krzysztof Tomasz
Published: February 2024

The unclear verse “Three Quarks for Muster Mark!”, introduced by James Joyce (1882–1941) to his novel entitled Finnegans Wake (first published in 1939), was a literary source for the English word quark denoting ‘an elementary particle with a fractional electric charge that is part of a proton, neutron or other interacting elementary particle’. The American physicist Murray Gell-Mann, winner of the Nobel Prize in Physics in 1969, was the first researcher to introduce the English word quark into scientific terminology as early as in 1964. After accepting his hypothesis of quarks in the world science, most physicists adopted the English term quark as standard in the physical terminology of most international languages (e.g. French quark, German Quark, Italian quark, Polish kwark, Portugal quark, Russian кварк, Spanish cuark, Turkish kuark, Ukrainian кварк ‘an elementary particle’) and it quickly became a widely recognized internationalism. It is not commonly known that Joyce’s verse facetiously imitated loud cries of German dairy women: Drei Mark für muster Quark! (literally “Three Marks for an excellent curd!”). In other words, E. quark ‘an elementary particle’ is motivated by the German term Quark m. ‘weiser Käse / curd, white cheese’, metaphorically ‘trifle, nonsense, trash, worthless thing’, which – according to most German and Slavic etymologists – represents an obvious Slavic borrowing (especially a Polish or Lower Sorbian loanword), cf. Pol. twaróg, dial. kwaruk m. ‘curd, white cheese’ (< Proto-Slavic *tvarogъ m. ‘id.’). It is suggested that the specialized term kwark represents the so called back-borrowing in the Polish language.

In Thailand, the number of particles matter with diameter of less than 2.5 microns or PM2.5 concentration exceed the standard in many areas, especially in Chiang Mai. This affects the image of the country in terms of economy, health, and environment. The objective of this research is to study the structure of model for PM2.5 concentration by using a Deep Belief Network (DBN) with the daily data set of PM2.5 concentration from the air quality monitoring station at Yupparaj Wittayalai School, Chiang Mai. The data was analyzed through an unsupervised path using the Minimizing Contrastive Divergence (MCD) algorithm, followed by a supervised path using Back-Propagation Neural Network (BPNN) algorithm to estimate the parameters of DBN. The result shows that the optimal DBN structure has 5 input nodes and 20 hidden neurons in the first hidden layer. This model has an 88.4 percent accuracy in forecasting PM2.5 concentration. In addition, this model can be applied for other weather forecasting such as rainfall or water level in a basin.

In this paper, a non-steady-state non-linear reaction diffusion in immobilized enzyme on the nonporous medium is considered for its mathematical analysis. The non-linear terms in this model are related to the Michaelis-Menten kinetics. For the considered model, the approximate analytical expressions of the substrate concentration and the effectiveness factor for the various geometric profiles of immobilized enzyme pellets are obtained using homotopy perturbation method (HPM). The obtained approximate analytical expressions proved to be fit for all values of parameters. Numerical solutions are also provided using the MATLAB software. When comparing the analytical and the numerical solutions, satisfactory results are noted. The effects of Thiele modulus and Michaelis-Menten kinetic constants on the effectiveness factor are also analyzed.

El caracol manzana (Pomacea canaliculata) (Lamarck) es la plaga que más problemas ha causado en los últimos años en los cultivos de arroz. Esta plaga ha reducido significativamente la productividad del arroz en todo el mundo. El presente trabajo se realizó en vía Salitre-Baba, en el km 38 en la provincia del Guayas, Ecuador 2020. Fue un ensayo experimental a nivel de campo donde se aplicaron diferentes dosis (un litro de quelato de cobre + agua ozonizada/hectárea) y (dos litros de quelato de cobre + agua ozonizada/hectárea). Para lo cual se utilizó un diseño de bloque completo al azar (DBCA) y 4 tratamientos, 1 testigo y 4 repeticiones. Una vez cosechado el arroz, los datos estadísticos relacionados con el rendimiento fueron recolectados. Los resultados demuestran que el rendimiento no se ve afectado por la aplicación de quelato de cobre y ozono y aunque no hubo diferencia significativa entre todos los tratamientos se observó que el mejor tratamiento fue el T4, que corresponde a la dosis de 2 L ha-1 de quelato de cobre mezclado con agua ozonizada con 2 ppm de concentración donde el rendimiento fue de 3 827.5 ±877.8 kg ha-1, mayor comparado con el T5 (testigo) que reflejo un rendimiento de 1 488.7 ±596.4 kg ha-1 significativamente inferior por la presencia y efectos del caracol. Se concluyó que el quelato de cobre con el agua ozonizada puede controlar el caracol manzana en el cultivo del arroz, además se observó un aumento de rendimiento en el grano.
The Common Cold

Published: February 2024

This paper models a new approach to theorizing topics via music informatics. Our case study for topic is winter as it appears in video game music. Like opera or oratorio, video game music leaves little ambiguity as to what the music ought to signify. Video games commonly have an icy or snowy area, complete with cold-weather creatures and landscapes as well as new game mechanics and music for the player to encounter. Our dataset has over 160 examples of such music, representing games on all mainstream platforms (Nintendo, PlayStation, computer, etc.) and spanning the years 1987–2020. Each example is tagged with its musical features. We define five core characteristics of the winter topic: heavy reverb, arpeggiated textures, metallic percussion instruments, plucked string instruments, and omission of membranophones. We also situate winter as a topic related to Christmas, ’80s music, and the waltz. Finally, we explore Nintendo’s idiosyncratic approach to winter music. Our study finds that instrumentation—particularly percussion—and audio technology are key considerations in establishing the winter topic in video game music. More broadly, we demonstrate the potential of computational musicology to augment and complement traditional approaches to topic theory, whether in relation to video game music or any other repertoire.
