В структуре онкологической заболеваемости рак легкого занимает лидирующие позиции во всем мире. Рак легкого, как и многие онкологические болезни, является многофакторным заболеванием, в развитии которого важную роль играют генетические факторы. В ряде эпидемиологических исследований, изучавших связь между полиморфизмом CYP1A1 Ile462Val и риском развития рака легкого противоречивы. Таким образом, мы провели исследование оценки связи между полиморфизмом Ile462Val в гене CYP1A1 и риском развития рака легкого в Якутии. Полученные результаты свидетельствуют о том, что мутантный аллель CYP1A1*G и гомозиготный генотип CYP1A1*G/G являются факторами риска развития рака легкого. При этом протективным эффектом обладали: дикий аллель CYP1A2*A и гетерозиготный CYP1A2*A^, гомозиготный CYP1A2*A/G генотипы.

Published: February 2024

SUTT is a high voltage overhead line with a power of 70 kV - 150 kV to distribute electric power from the generating center to the substation or from substation to substation. The purpose of this study was to obtain modeling of lightning strike density on the 150 kV transmission line between Parit Baru substation and Senggiring substation using geostatistical approaches, namely IDW methods (Inverse Distance Weighted). In identifying the level of vulnerability to lightning strikes, Cloud to Ground lightning event data (2018–2020) is used. The aim of this research is to obtain the density pattern of lightning strikes on the 150 kV transmission line between the Parit Baru substation and the Senggiring substation. The process in ArcGIS 10.8 software aims to obtain lightning strike density and display the results of the lightning strike density map. Based on the results of data processing for 3 years, the highest density of lightning strikes occurred in 2019 in Segedong District at 54.52 strikes/km². Meanwhile, the lowest density of lightning strikes occurred in 2018 in East Mempawah District, amounting to 2.86 strikes/km². Based on the lightning strike density map per grid on the 150 kV transmission line between Parit Baru substation and Senggiring substation for 3 years, the results obtained for the highest lightning strike were 36 strikes/km² while for the lowest strike it was 1 strike/km². From this research, it was found that there were 15 transmission towers that passed a high density of lightning strikes with a strike range of 25–36 strikes/km² and the highest lightning strike occurred at tower number 31, number 30, and number 29, amounted to 36 strikes/km².

Upregulation of L-type calcium channels (LTCCs) is implicated in a range of cardiovascular and neurological disorders. Therefore, the development of toolboxes that unlocks fast imaging protocols in live cells are coveted. Herein, we report a library of first-in-class novel far-red small-molecule-based fluorescent ligands (FluoDiPines), able to target LTCCs. All fluorescent ligands were evaluated in whole-cell patch-clamp and live-cell Ca2+ imaging whereby Fluodipine 6 was found the best candidate for live-cell fluorescence imaging. Low concentration of FluoDiPine 6 (50 nM) and a quick labelling protocol (5 min) are successfully applied to fixed- and live-cells to image LTCCs with good specificity.
Molecular driving forces for water adsorption in MOF-808: A comparative analysis with UiO-66
Authors: Frank Hilliary O. , Paesani Francesco
Published: February 2024

Metal-organic frameworks (MOFs), with their unique porous structures and versatile functionality, have emerged as promising materials for adsorption, separation, and storage of diverse molecular species. In this study, we investigate water adsorption in MOF-808, a prototypical MOF that shares the same secondary building unit (SBU) as UiO-66, and elucidate how differences in topology and connectivity between the two MOFs influence the adsorption mechanism. To this end, molecular dynamics (MD) simulations were performed to calculate several thermodynamic and dynam- ical properties of water in MOF-808 as a function of relative humidity (RH), from the initial adsorption step to full pore filling. At low RH, the μ3-OH groups of the SBUs form hydrogen bonds with the initial water molecules entering the pores, which triggers the filling of these pores before the μ3-OH groups in other pores become en- gaged in hydrogen bonding with water molecules. Our analyses indicate that the pores of MOF-808 become filled by water sequentially as the RH increases. A similar mechanism has been reported for water adsorption in UiO-66, a MOF that shares the same SBU with MOF-808. Despite this similarity, our study highlights distinct ther- modynamic properties and framework characteristics that influence the adsorption process differently in MOF-808 and UiO-66.

Plastics are indispensable materials for packaging and many products from our daily life and their recycling is essential to ensure a circular economy. In this study, −SO3H modified-MXene, Ti3C2, was used as a recoverable solid acid catalyst for up-cycling of polyethylene terephthalate (PET) to terephthalic acid (TPA) and ethylene glycol (EG) by hydrolysis. For the addition of −SO3H groups to the Ti3C2Tx surface (where Tx represents the surface moieties such as -OH or -O), sulfonation with an aryl diazonium salt obtained from sulfanilic acid was employed. X-ray photoelectron and Fourier transform infrared spectroscopies analyses provided a direct indication that sulfonation of the Ti3C2Tx was successfully performed, while X-ray diffraction and Transmission electron microscopy analyses evidence the presence of −SO3H groups in between the layers of Ti3C2Tx due to the increases of the interlayer spacing through the intercalation of functional groups. The higher the concentration of acid groups, the higher the interlayer spacing. The depolymerisation of PET in water occurred with a very good isolated yield in TPA (99%) for the MXene with the highest amount of sulfonic acid groups. We can conclude that the acidity is mandatory to perform the hydrolysis reaction, in agreement with the acidity measurements, which shows that the MXene modified with the highest amount of derived sulfonic acids contains the highest amount of acidity. Nevertheless, the accessibility to the acidic sites is a key factor that promotes the 2D acid-modified MXene materials as important catalysts for PET up-cycling to TPA.
CageCavityCalc (C3): A computational tool for calculating and visualizing cavities in Molecular Cages
Authors: Martí-Centelles Vicente , Piskorz Tomasz Krzysztof , Duarte Fernanda
Published: February 2024

Organic(porous) and metal-organic cages are promising biomimetic platforms with diverse applications spanning recognition, sensing and catalysis. The key to the emergence of these functions is the presence of well-defined inner cavities capable of binding a wide range of guest molecules and modulating their properties. However, despite the myriad cage architectures currently available, the rational design of structurally diverse and functional cages with specific host–guest properties remain challenging. Efficiently predicting such properties is critical for accelerating the discovery of novel functional cages. Herein, we introduce CageCavityCalc (C3), a Python-based tool for calculating the cavity size of molecular cages. The code is available on GitHub at https://github.com/VicenteMartiCentelles/CageCavityCalc. C3 utilizes a novel algorithm that enables the rapid calculation of cavity sizes for a wide range of molecular structures and porous systems. Moreover, C3 facilitates easy visualization of the computed cavity size alongside hydrophobic and electrostatic potentials, providing insights into host-guest interactions within the cage. Furthermore, the calculated cavity can be visualized using widely available visualization software, such as PyMol, VMD, or Chimera. To enhance user accessibility, a PyMol plugin has been created, allowing non-specialists to use this tool without requiring computer programming expertise. We anticipate that the deployment of this computational tool will significantly streamline cage cavity calculations, thereby accelerating the discovery of functional cages.

Published: February 2024

Curved aromatic hydrocarbons often display better solubility and more desirable electronic properties in comparison to their flat counterparts. Macrocyclic curved aromatics possess these traits as well as shape-persistent pores ideal for host-guest interactions. A quintessential macrocyclic curved aromatic molecule is the cycloparaphenylene, or [n]CPP. Our group has developed a new class of these carbon nanohoops, called [n+1]CPPs, that incorporate a strained alkyne (“+1”) into the carbon backbone. We have previously shown the [n+1]CPPs to be a promising new class of strain-promoted azide-alkyne cycloaddition click reagents. Herein, we show that the [n+1]CPPs can also be converted into pinwheel-like multi-pore large molecules via a straightforward and high yielding metal-mediated alkyne cyclotrimerization reaction. We provide insight into suitable metals for this transformation, the photophysics of these trimeric molecules, as well as their strain profiles and crystal packing.
Plasma-activated tight and uniform grown of metal-organic frame-work on carbon cloth for stable Li metal anode
Authors: Zhuang Zilong , Rao Xinqiang , Zhang Fuming , Jadhav Vijaykumar , Tan Daniel
Published: February 2024

The significant expansion in volume and the formation of dendrites on lithium metal anodes lead to poor electrochemical reversi-bility. In this study, ZnO, N-dually doped carbon (p-ZNCC) was synthesized using oxygen plasma assistance and zeolitic imidazo-late framework-8 (ZIF-8). The use of plasma ensures tight and uniform growth of ZIF-8 particles on carbon fiber, promoting the formation of lithiophilic pyrrolic N after sintering. This enables uniform lithium deposition and rapid lithium-ion diffusion during the operation. The resulting lithium electrode with the p-ZNCC host (p-ZNCC-Li) exhibits stable lithium stripping/plating for up to 3000 h and a voltage hysteresis of 36 mV when cycled at 10 mA cm-2-10 mAh cm-2. Electrochemical impedance spectroscopy (EIS) reveals low charge transfer resistance and a high diffusion coefficient for p-ZNCC-Li. Moreover, the LNMO||p-ZNCC-Li cell demonstrates improved capacity retention at 1 C after 250 cycles. This study introduces a novel approach to growing metal-organic frameworks (MOFs) with dual lithiophilic spots on carbon cloth, promising advancements in lithium metal anode design.
Na vs Li Metal Anodes For Batteries: Unraveling Thermodynamic and Electronic Origins of Voids and Developing Descriptors for Artificial Surface Coatings
Authors: Venturi Victor , Freitas Rodrigo , Abate Iwnetim
Published: February 2024

Techno-economic, humanitarian, and safety concerns limit the possible uses of conventional lithium-ion and lithium-metal batteries. Sodium-based batteries constitute a promising alternative to address these issues; however, due to the similarities between the two alkali metals, they present similar failure modes as their lithium counterparts. In this work, we focus on one of such failure mechanisms: the thermodynamically-driven accumulation of vacancies on the surface of the metallic anode, which leads to the formation of voids and pits, detrimental to battery performance and cycle life. We investigate the differences in behavior between anode/coating interfaces of both lithium and sodium. Adhesion energy, a descriptor previously argued to be a reliable design principle for lithium metal anodes, is found to not exhibit the same predictive power for sodium metal architectures: in cases where vacancy congregation is not thermodynamically favorable for isolated sodium slabs, we find strong interfacial interactions to have adverse effects on void formation. By studying select coating materials, we also reveal that these material interactions at alkali/coating interfaces are highly nuanced, and that the field of surface science and engineering is ripe with opportunities for further discovery and tuning of surface properties via coating selection.
Organisational renewal model for leveraging a bank’s sustainability and continuity during periods of discontinuities: a perspective from the caribbean financial markets
Authors: Jennifer Davis Adesegha
Published: February 2024

As financial institutions are often faced with a series of turbulences that unfold in the Caribbean financial markets, frequent organisational renewal and self-regeneration become crucial for bolstering a bank's continuity and sustainability. In that context, this study uses a qualitative research method to evaluate the effectiveness of the organizational renewal strategies that are often used by Caribbean banks during periods of turbulence as well as the major impediments of such strategies. Through such analysis, the study aimed to discern the organisational renewal model that can be extracted and suggested for leveraging a bank's sustainability and continuity in the periods of discontinuities. During periods of turbulence, findings from different banks that were drawn from St. Lucia, Barbados, Bahamas, St. Vincent, Grenada and the Dominican Republic signified the organizational renewal strategies that are often used by Caribbean banks to encompass financial service innovations, digital transformation, value-based marketing and CSR-based banking model. But even if that is the case, the efficacy of some of the organisational renewal strategies to turn around the bank's performance during turbulence was still found to be undermined by the hefty costs of change that must be incurred and organisational inertia that limits the flexibility and agility required for the banks in distress to respond. To mitigate such constraints, the study suggests the Organisational Renewal and Self-Regeneration Model which the contemporary banks can adopt to bolster their adaptability, continuity and sustainability during periods of discontinuities. But even if usage of such a model will leverage a bank's sustainability and continuity amid the Caribbean financial markets' discontinuities, future studies must still explore the impact of organisational renewal on a bank's liquidity risks' mitigation during periods of turbulence.
Direct Torque Control (DTC) and three phase induction motor simulation in MATLAB/Simulink
Authors: M. Theodore Kingslin
Published: February 2024

Direct Torque Control (DTC) is considered one of the most effective methods for the decoupled control of electromagnetic torque and speed in an induction motor. In DTC, torque is directly regulated by the torque angle, defined as the difference between the stator flux angle and the rotor flux angle. The advantages of employing DTC include the simplicity of implementation, a reduced number of controllers, excellent torque dynamics, and decreased torque oscillation. Implementing DTC with microcontrollers is easier than with Field-Oriented Control (FOC). This paper discusses the operational principles of DTC and highlights its advantages over the FOC method. The goal is to independently control stator flux linkages, rotor flux linkages, electromagnetic torque, and speed by providing the appropriate switching pulses to the Voltage Source Inverter (VSI). To validate the effectiveness of this control method, we modeled DTC and a 6-kW induction motor using MATLAB/Simulink. The results confirm the efficacy of DTC for decoupled control of torque and speed in the induction motor, demonstrating lower switching losses and excellent torque dynamics. The induction motor was tested under both no-load and a 10 Nm load conditions.
Low Complexity Stopping Rule for Turbo Decoding: the Max-log Criterion
Authors: Ouardi Aissa
Published: February 2024

This paper presents a new stopping criterion for turbo decoding. It is based on the selection of the maximum log-alphas calculated by the log-MAP algorithm. The sum of these maximum alphas is compared with a threshold value. Then, a decision on the end of decoding is taken. Simulation results show that the max-log criterion offers the same performance as the sum-alpha and sum-log criteria, while maintaining the same complexity level. The max-log criterion uses only the max operator to select maximum alphas and a summation. Therefore, the proposed criterion is faster and offers lower complexity.

Published: February 2024

Within the realm of machine learning, kernel methods stand out as a prominent class of algorithms with widespread applications, including but not limited to classification, regression, and identification tasks. Our paper addresses the challenging problem of identifying the finite impulse response (FIR) of single-input single-output nonlinear systems under the influence of perturbations and binary-valued measurements. To overcome this challenge, we exploit two algorithms that leverage the framework of reproducing kernel Hilbert spaces (RKHS) to accurately identify the impulse response of the Proakis C channel. Additionally, we introduce the application of these kernel methods for estimating binary output data of nonlinear systems. We showcase the effectiveness of kernel adaptive filters in identifying nonlinear systems with binary output measurements, as demonstrated through the experimental results presented in this study.

Money Supply, Inflation and Budget Deficit in Russia Compared to the United States
Authors: Zhukov P. E.
Published: February 2024

The author examines the causes and sources of the depreciation of money in Russia compared with that in the United States. The subject is causal connections between the budget deficit, money supply, and the depreciation of money. The relevance of the research for Russia is determined by concerns about macroeconomic stability and high inflation. In the case of the United States, an increase in the money supply and an inflation spike occurred because of the debt financing of the federal budget deficit. The scientific novelty of the paper lies in considering the two main options for monetary policy to support the liquidity of public debt: hard and soft, and the analytical methods and results of the research. One of the important scientific results is that the burden of public debt should be measured not as the ratio of public debt to gross domestic product (GDP) but as the share of public debt in a bond market. The second scientific result is very important for the practice: during 2011–2022, in the eight biennial periods, the GDP deflator was approximately equal to the growth of the money supply M2 minus GDP growth. Thus, the depreciation of money was directly caused by monetary policy. In the other three biennial periods, a substantial difference was observed, probably because of external shocks. As the method of the study, the author estimated the effect of interest rates caused by crowding out corporate debt by public debt. It was substantiated that to obtain the effects of soft monetary policy and thus the increase of M2 to GDP deflator, it is essential to use biennial periods. Based on the results of the analysis, it was revealed that, particularly in 2021–2022, the growth of the GDP deflator amounted to 139.8% and was due to the growth of the money supply M2 by 140.5%. At the same time, the effect on GDP growth was insignificant, at 3.4%. The key conclusion is that for the implementation of macroeconomic stability policies, it is necessary to manage the expansion of the M2 money supply, the exchange rate, and to use the GDP deflator as an important indicator in addition to the inflation index — consumer price index. A good way to achieve this is to adopt a special law for controlling inflation, similar to the USA Inflation Reduction Act.

Polish 'pieszy' and English 'foot': An analysis of a pair of cognates
Authors: Potrykus Anna
Published: February 2024

The research concentrates on investigating the etymological relationship between the Polish term pieszy ‘pedestrian, on foot’, and the English word foot, both tracing their origins back to a common Proto-IndoEuropean root *ped-. The objective of this study is to recognize and document the various morphological, phonological, and semantic changes that this shared ancestral word has experienced throughout its evolution. The study intends to prove that the Polish word pieszy and the English word foot represent cognates by demonstrating their shared elements and explaining changes that affected them.

Theorems on direct and inverse approximation by algebraic polynomials and piecewise polynomials in the spaces Hm(a, b) and Bs2,q(a, b)
Authors: Dautov R. Z.
Published: February 2024

The best estimates for the approximation error of functions, defined on a finite interval, by algebraic polynomials and piecewise polynomial functions are obtained in the case when the errors are measured in the norms of Sobolev and Besov spaces. We indicate the weighted Besov spaces, whose functions satisfy Jackson-type and Bernstein-type inequalities and, as a consequence, direct and inverse approximation theorems. In a number of cases, exact constants are indicated in the estimates.
When the Stomach Pain Is Literally “In Your Head”

Abdominal epilepsy (AE) is an extremely rare condition, classified as temporal lobe epilepsy, and is usually a diagnosis of exclusion. Temporal lobe epilepsy often has no clear cause, although it may be associated with diseases such as temporal lobe sclerosis, dysembryoplastic neuroepithelial tumours, and other benign tumours, as well as arterio-venous malformations, gliomas, defects in neuronal migration, or lesions of the cortex caused by encephalitis. AE is more common in children but has been reported in adults. AEs are characterised by recurrent and unexplained gastrointestinal symptoms such as seizure pain, nausea, bloating and diarrhoea, which improve with antiepileptic treatment. Given the vague nature of these symptoms, patients are at high risk of misdiagnosis. An electroencephalogram and neuroimaging of the brain are needed to confirm the diagnosis.
We present the clinical case of a 67-year-old female patient who was investigated at the Gastroenterology Department for a sharp pain in the left side of the abdomen, frequent abdominal distension and gurgles, diarrhoeal episodes, weight loss, paroxysmal hallucinations, and headaches. After a thorough gastroenterological examination, consultations with a psychiatrist and a neurologist, an MRI and an EEG were performed and the patient was diagnosed with focal temporal lobe epilepsy.
Synthesis of ketones through aerobic transition metal-catalyzed cross-coupling of thioesters.

Published: February 2024

Asymmetric diaryl ketones are an important class of compounds in organic chemistry due to their presence in natural products, synthesis, cosmetics as well as in biological active compounds. The aim of this project was to expand the scope of thiophilic metal carboxylates catalysts that can be applied to the aerobic Liebeskind-Srogl cross coupling reaction between various thioesters and phenylboronic acids. Thioesters bearing electron neutral, withdrawing and donating groups were successfully synthesized in yields ranging from 35 to 54%Xcv. The electron neutral thioester was used in the optimization of the aerobic Liebeskind-Srogl reaction and CuMeSal proved to be the most effective catalyst in this protocol. CuMeSal was applied in the aerobic synthesis of the asymmetric diaryl ketones bearing a wide range of functional groups including CF3, SMe, OMe and F yielding up to 65% in 24hrs. Aerobic Liebeskind-Srogl cross-coupling reaction was applied in the successful synthesis of chalcones, through the coupling of commercially available phenylboronic acids with previously synthesised thioesters catalysed by CuMeSal in DMF for 24hrs,furnishing desired products in poor to excellent yields 26-89%.
The impact of protected areas on the livelihoods of local communities. A case of Khula village, KwaZulu-Natal, South Africa.
Authors:   , Bafana Ronald Mpilo
Published: February 2024

The purpose of the study was to investigate the lived experiences of the local communities that live adjacent to protected areas (PA) in South Africa using a case study of Khula Village which is located in KwaZulu-Natal. The literature which was reviewed acknowledges the importance of protected areas however the communities who reside close to protected areas are not fully benefiting from the protected area management, leading to conflicts between management authorities and local communities. This study has sought insight from community members in Khula Village in pursuit of the overarching research question: a) What are the benefits of protected areas management to local communities? b) What are the factors that hinder the flow of benefits? and c) How is the protected area perceived? The individuals interviewed provided data for the research questions. The findings that I gathered suggest that this community has nothing against conservation but the issue is how it is done. The community is not enjoying the benefits of conservation this has led to clashes between the iSimangaliso Wetland Park Authority (IWPA) and the community, unfortunately some of these clashes have often led to fatalities. By applying the political ecological approach (Robbins, 2012), as a basis of analysis my study suggests that the approach of management of IWPA is unsustainable; not involving of local people from protected areas management leads to conflict; the state control of the PA has negatively affected the livelihood of the local community. The study findings have recommendations that may help inform the government and management agencies to manage PA more sustainably.
Chromatic Function in Schoenberg’s Little Piano Piece, op. 19, no. 1
Authors: Hier David
Published: February 2024

The revival ofFormenlehrestudies has initiated a renewed interest in formal functions in atonal music. Schoenberg, who pioneered the study of formal functions, did not extensively analyze his atonal music from a formal point of view. Recent scholars, however, have drawn parallels between the formal construction of his atonal music and common-practice tonal music. One impediment to such analysis is the lack of a theory of counterpoint and harmony upon which formal-functional analysis rests. I propose a normative contrapuntal-harmonic structure for Schoenberg’s atonal music I call the “chromatic cadence.” I trace its origins to voice-leading techniques used by Schoenberg in his earlier tonal music and develop fundamental principles that guide the analysis and identification of the cadence in his atonal music. I conclude with a detailed analysis of Schoenberg’s piano piece, op. 19, no. 1, in which I examine the interrelationship of its motivic construction, contrapuntal-harmonic structure, and its formal functions.
Klangfarbenmelodie, Chromophony, and Timbral Function in Arnold Schoenberg’s “Farben”
Authors: Zeller Matthew
Published: February 2024

Arnold Schoenberg’s concept ofKlangfarbenmelodie(melody of timbres) is one of the most important yet least understood compositional innovations of the twentieth century. By examining significant factors inKlangfarbenmelodie’s theoretical formulation, proposing functional roles that timbre can fulfill, and locating examples of timbre realizing those musical functions in “Farben,” the third of Schoenberg’sFive Orchestral Pieces, Op. 16, this article demonstrates some of the ways timbre can shape music and our musical experience. While musical logic based on timbre operates according to laws of its own, not those of pitch, parallels can nonetheless be drawn between harmonic functions and timbral functions. Timbral developments are shown to articulate the formal process in “Farben” and create coherent progressions, modulations, and cadences that illustrate some possibilities of how timbre can function in music.
Rain Rain Go Away: A Snapshot of the Flood 2022 and Way Forward
Authors: Sobia Rose  , Abedullah
Published: February 2024

The devastations caused by the recent floods in Pakistan are the result of poor management. Despite several warnings of an unusual rainfall during the months of July and August, a lack of preparedness resulted in a huge catastrophe. The knowledge brief in hand provides a snapshot of the extent of rainfall and subsequent floods, as well as the losses that occurred after the disaster. The major threats from the recent floods include the threat to the food security of an already deprived population; loss of education and health; and an increase in social unrest due to more criminal activity. To tackle the issue in future both structural and non-structural measure should be adopted. Structural measures are long-term development interventions while non-structural measures are based on shortterm response to build community resilience. We are compelled to live with the floods due to our topographic situation. Better management and adaptation stratifies can help to minimise the losses in case of next disaster.
Will the Import Ban Prove Effective?
Authors: Mohammad Shaaf Najib
Published: February 2024

Pakistan has for decades now been facing a financing crisis. The expenditures have always remained significantly higher than the revenues making the governments look to various sources to finance this gap. One major reason for the country’s lackluster performance in managing its expenses stems from the import dependency of the economy. Not only do we import the raw materials for our industries, but the local demand for commodities, agricultural and manufactured, is met through imports. While Pakistan’s import per capita remains lower than other regional countries, the low export value which has remained rather stagnant over years is a major cause of concern. Figure 1 below depicts Exports and Imports of Pakistan during the last decade.
