Papua, region in eastern Indonesia which has a separatist movement threatening Indonesia's sovereignty. Soldiers of Indonesia National Army (TNI) as a means of national defense seeks to integrate the TNI's strengths through the establishment of a Joint Defense Area Command III (Kogabwilhan-III) defense policy which covers the Maluku and Papua regions. The communication dimension is seen as important in the success of policy implementation, so the purpose of this research is to analyze the communication dimension in the implementation of Kogabwilhan III policy and identify the factors that influence the implementation of Kogabwilhan III from a communication perspective and what the challenges are. This study using a qualitative descriptive method to explore cases in depth from various sources of information at a certain time. The results of the study explain that the implementation of the Kogabwilhan III policy in the communication dimension has three indicators, i.e. transmission, clarity and consistency indicators. Reviewing the challenges and obstacles, innovation is needed in the communication dimension by adding indicators of local wisdom. Moreover, policy implementation of Kogabwilhan III is divided into two forms of communication: internal communication and external communication.

Tiu ĉi studo esploras la influojn de gepatra lingvo sur la lernadon de esperanto pere de du taskoj: juĝado de akceptebleco de frazoj kaj libera priskribado de bildo. Partoprenis entute 111 parolantoj el anglalingvanoj, perslingvanoj, hungarlingvanoj kaj ruslingvanoj, malsamaj je la sperto en esperanto: komencantoj, progresantoj kaj spertuloj. Testitaj fraztrajtoj estis tri-specaj: tiaj, kiuj inkludis sintagmo-konservantan disigon (Grandan hundon renkontis la knabo sur la strato.), tiaj, kiuj inkludis sintagmo-rompantan disigon (Grandan li akiros sukceson.) kaj tiaj, en kiuj mankis kromvorto (Mi rakontos kion mi vidis.). Tiuj ĉi transformitaj frazoj estis parigitaj respektive kun siaj bazaj frazoj: tiaj, kiuj ne inkludis sintagmo-konservantan disigon (La knabo renkontis grandan hundon sur la strato.), tiaj, kiuj ne entenis sintagmo-rompantan disigon (Li akiros grandan sukceson.), kaj tiaj, kiuj inkludis kromvorton (Mi rakontos tion, kion mi vidis.). Ĉefaj trovaĵoj estis: (1) diferenco de jugado inter la bazaj kaj la transformitaj frazoj okazis depende de tio, ĉu la gepatra lingvo permesis aŭ ne permesis la kritajn fraztrajtojn. Tio ĉi okazis speciale ĉe komencantoj el perslingvanoj, hungarlingvanoj kaj ruslingvanoj, kiam ili juĝis frazojn kiuj inkluzivis la du tipojn de disigo. (2) La diferenco malgrandigis proporcie al spertiĝo en esperanto. Tio ĉi estis plej rimarkebla ĉe perslingvanoj kaj hungarlingvanoj, kiam ili jugis la sintagmo-konservantajn frazojn. (3) Spertuloj el la kvar lingvanoj donis preskaŭ samnivelan juĝadon precipe al la frazoj rilatantaj al la du specoj de disiĝo.

Interpersonal forgiveness: validation of the Enright Forgiveness Inventory (EFI-30) in the Spanish sample
Authors: Kasprzak Agata , Martinez-Diaz Pilar , Molinero Caparrós Clara , Enright Roberth
Published: August 2023

Background: Numerous studies have demonstrated the importance of interpersonal forgiveness after a specific offense for improving the health and well-being of individuals. Despite its importance, there is an evident lack of forgiveness evaluation instruments adapted to the Spanish context. The Enright Forgiveness Inventory (EFI-30) is the questionnaire that implements one of the most established and recognized theoretical models in the area of forgiveness. The aim of the present study is to adapt the EFI-30 for the Spanish population and evaluate its psychometric properties. Method: A sample of 426 undergraduate and graduate students (98 men, 328 women) aged from 18 to 30 years (M = 21.24; SD = 2.91), completed the EFI-30 after its adaptation to the Spanish context, as well as the Transgression Related Interpersonal Motivations Inventory (TRIM-18), the Remedial Strategies Scale (RSS) and the Depression Anxiety and Stress Scale (DASS-21). Results: The Confirmatory Factor Analysis showed a good fit to the original six-factor structure (CFI = .91, TLI = .90, IFI = .91, RMSEA = .067). The reliability of these subscales and the instrument was similar to the original version. The results showed adequate criteria and convergent validity. Conclusions: The EFI-30 shows adequate psychometric properties within the Spanish context and is an appropriate instrument for evaluating interpersonal forgiveness of a specific offense in research and clinical intervention.

Some numerical signiﬁcance of the Riemann zeta function
Authors: Enoch Opeyemi O. , Salaudeen Lukman O.
Published: August 2023

In this paper, the Riemann analytic continuation formula (RACF) is derived from Euler’s quadratic equation. A nonlinear function and a polynomial function that were required in the derivation were also obtained. The connections between the roots of Euler’s quadratic equation and the Riemann zeta function (RZF) are also presented in this paper. The method of partial summation was applied to the series that was obtained from the transformation of Euler’s quadratic equation (EQE). This led to the derivation of the RACF. A general equation for the generation of the zeros of the analytic continuation formula of the Riemann zeta equation via a polynomial approach was also derived and thus presented in this work. An expression, which was based on a polynomial function and the products of prime numbers, was also obtained. The obtained function thus afforded us an alternative approach to defining the analytic continuation formula of the Riemann Zeta equation (ACFR). With the new representation, the Riemann zeta function was shown to be a type of function. We were able to show that the solutions of the RACF are connected to some algebraic functions, and these algebraic functions were shown to be connected to the polynomial and the nonlinear functions. The tables and graphs of the numerical values of the polynomial and the nonlinear function were computed for a generating parameter, k, and shown to be some types of the solutions of some algebraic functions. In conclusion, the RZF was redefined as the product of a derived function, R(tn,s), and it was shown to be dependent on the obtained polynomial function.
The correlation of geothermal energy potential deduced from aeromagnetic and aeroradiometric data of Akiri and anvirons, North-Central Nigeria
Authors: Ikumbur Bemsen Emmanuel
Published: August 2023

The aeromagnetic and aeroradiometric data were combined to investigate the geothermal energy potential of Akiri and Environs, North-Central Nigeria. The aeromagnetic and aeroradiometric data were obtained from the Nigerian Geological Survey Agency (NGSA), Abuja. The data consists of nine square map sheets of Wamba, Kwolla, Shendam, Lafia, Akiri, Ibi, Makurdi, Akwana and Wukari. The LANDSAT imagery data of the study area was obtained from the National Centre for Remote Sensing, Jos. The spectral analysis method was applied to aeromagnetic data to obtain the geothermal parameters of the magnetic sources. The results show that the depth-to-top of magnetic sources in the study area ranges between 0.76 and 4.46 km; while the depth-to-centroid ranges between 7.29 and 19.6 km. The depth-to-bottom of magnetic sources corresponds to the Curie point depth (CPD) in the study area which is the depth at which magnetic rocks lose their magnetism. The results show that the CPD varies between 12.70 and 37.22 km, the geothermal gradient varies between 15.58 and 45.67 ◦C/km, and the geothermal heat flow varies between 38.9 and 114.17 mW/m2. Two dimensional structural models were constructed to show the estimated depths at each profile taken. The models show uplifted crust and mantle in some areas due to magmatic intrusions which gave rise to low CPDs (12 to 28 km) which resulted to high geothermal heat flow values (60 to 115 mW/m2). The results show that there are low values of CPD in some areas which indicates that the study area has geothermal energy potential. The study shows that the geothermal energy potential deduced from aeromagnetic data correlates well with the geothermal energy potential deduced from aeroradiometric data.
Modelling patients waiting and service time by ARIMA model: a case of Federal University Gusau clinic
Authors: Moyi Aliyu , Bello Kabir , Ibidoja Olayemi , Muhammad Garba
Published: August 2023

The ability to model and forecast waiting and service time to increase patients' satisfaction, reduce waiting time, avoid casualties, and increase efficiency in service delivery is crucial. It encourages the identification of future pressure by using the relevant key performance indicators. In this paper, the ARIMA model is used to study the waiting and service time of patients at the {\it Federal University Gusau} Health Services Clinic. The system was a single, time-independent arrival with many service points. Based on the results found in the waiting and service processes, the service time has a lower mean and variance when compared to the waiting time. The waiting time has a lower skewness and kurtosis when compared to the service time. The Ljung-Box (Q) Statistic test shows that the correlation in the time series has been adequately captured for the waiting and service time processes, though the waiting and service time processes have 4 and 10 outliers respectively. The ARIMA (0,1,2) and ARIMA (2,1,1) are selected for modelling the waiting and service time respectively based on the evaluation metrics.
Proximate Analysis of Telfairia occidentalis (fluted pumpkin) and Telfairia pedata (oyster nut) leaves consumed in Katsina Metropolis: a comparative study
Authors: Auwal Yahaya , Murtala Abdulhamid , Imam Naziru , Barde Magaji Ilu
Published: August 2023

Telfairia occidentalis and Telfairia pedata are highly valued for their nutritious seeds and are consumed widely in sub-Saharan Africa. However, the potential application of their leaves was not thoroughly investigated and documented. Therefore, proximate analysis of their leaves for potential applications is sacrosanct. Samples of the leaves were obtained from the Katsina metropolis and analysed for their proximate compositions using standard analytical procedures. The result indicates that the percentage carbohydrate, crude fibres, and moisture contents values for Telfairia pedata and Telfairia occidentalis leaves were 49.23±0.79, 19.50±0.31, 62.06±0.49 and 49.44±0.55,14.68±1.04, and 71.40±0.31, respectively. The crude protein, crude fat, and ash contents were 16.04±0.51, 2.00±0.50, 13.33±0.31 and 22.45±0.50, 4.80±0.34, and 8.60±0.21 for Telfairia pedata and Telfairia occidentalis, respectively. The crude fibre and ash content were higher in Telfairia Pedata than in Telfairia Occidentalis leaves. There was no significant difference in the carbohydrate content of the leaves. However, the crude protein, moisture content, and lipid were higher in the Telfairia Occidentalis leaf. The leaves could be a good carbohydrate, protein, and dietary fibre source. However, further study is recommended on the leaves’ anti-nutrients, mineral and phytochemical analyses
An Improved Object Detection and Trajectory Prediction Method for Traffic Conflicts Analysis
Authors: Yang Lu , Mohamed Ahmad Sufril Azlan Bin , Ali Majid Khan Bin Majahar
Published: August 2023

Although computer vision-based methods have seen broad utilisation in evaluating traffic situations, there is a lack of research on the assessment and prediction of near misses in traffic. In addition, most object detection algorithms are not very good at detecting small targets. This study proposes a combination of object detection and tracking algorithms, Inverse Perspective Mapping (IPM), and trajectory prediction mechanisms to assess near-miss events. First, an instance segmentation head was proposed to improve the accuracy of the object frame box detection phase. Secondly, IPM was applied to all detection results. The relationship between them is then explored based on their distance to determine whether there is a near-miss event. In this process, the moving speed of the target was considered as a parameter. Finally, the Kalman filter is used to predict the object's trajectory to determine whether there will be a near-miss in the next few seconds. Experiments on Closed-Circuit Television (CCTV) datasets showed results of 0.94 mAP compared to other state-of-the-art methods. In addition to improved detection accuracy, the advantages of instance segmentation fused object detection for small target detection are validated. Therefore, the results will be used to analyse near misses more accurately.

The locus coeruleus (LC) is an important noradrenergic nucleus that has recently attracted a lot of attention because of its emerging role in cognitive and psychiatric disorders. Although previous histological studies have shown that the LC has heterogeneous connections and cellular features, no studies have yet assessed its functional topography in vivo, how this heterogeneity changes over aging, and whether it is associated with cognition and mood. Here, we employ a gradient-based approach to characterize the functional heterogeneity in the organization of the LC over aging using 3T resting-state fMRI in a population-based cohort aged from 18 to 88 years of age (Cambridge Centre for Ageing and Neuroscience cohort, n=618). We show that the LC exhibits a rostro-caudal functional gradient along its longitudinal axis, which was replicated in an independent dataset (Human Connectome Project [HCP] 7T dataset, n=184). Although the main rostro-caudal direction of this gradient was consistent across age groups, its spatial features varied with increasing age, emotional memory, and emotion regulation. More specifically, a loss of rostral-like connectivity, more clustered functional topography, and greater asymmetry between right and left LC gradients was associated with higher age and worse behavioral performance. Furthermore, participants with higher-than-normal Hospital Anxiety and Depression Scale (HADS) ratings exhibited alterations in the gradient as well, which manifested in greater asymmetry. These results provide an in vivo account of how the functional topography of the LC changes over aging, and imply that spatial features of this organization are relevant markers of LC-related behavioral measures and psychopathology.

Predator-prey arms races have led to the evolution of finely tuned disguise strategies. While the theoretical benefits of predator camouflage are well established, no study has yet been able to quantify its consequences for hunting success in natural conditions. We used high-resolution movement data to quantify how barn owls (Tyto alba) conceal their approach when using a sit-and-wait strategy. We hypothesized that hunting barn owls would modulate their landing force, potentially reducing noise levels in the vicinity of prey. Analysing 87,957 landings by 163 individuals equipped with GPS tags and accelerometers, we show that barn owls reduce their landing force as they approach their prey, and that landing force predicts the success of the following hunting attempt. Landing force also varied with the substrate, being lowest on man-made poles in field boundaries. The physical environment, therefore, affects the capacity for sound camouflage, providing an unexpected link between predator-prey interactions and land use. Finally, hunting strike forces in barn owls were the highest recorded in any bird, relative to body mass, highlighting the range of selective pressures that act on landings and the capacity of these predators to modulate their landing force. Overall, our results provide the first measurements of landing force in a wild setting, revealing a new form of motion-induced sound camouflage and its link to hunting success.

Numerous roles for the Alk receptor tyrosine kinase have been described in Drosophila, including functions in the central nervous system (CNS), however the molecular details are poorly understood. To gain mechanistic insight, we employed Targeted DamID (TaDa) transcriptional profiling to identify targets of Alk signaling in the larval CNS. TaDa was employed in larval CNS tissues, while genetically manipulating Alk signaling output. The resulting TaDa data were analyzed together with larval CNS scRNA-seq datasets performed under similar conditions, identifying a role for Alk in the transcriptional regulation of neuroendocrine gene expression. Further integration with bulk and scRNA-seq datasets from larval brains in which Alk signaling was manipulated identified a previously uncharacterized Drosophila neuropeptide precursor encoded by CG4577 as an Alk signaling transcriptional target. CG4577, which we named Sparkly (Spar), is expressed in a subset of Alk-positive neuroendocrine cells in the developing larval CNS, including circadian clock neurons. In agreement with our TaDa analysis, overexpression of the Drosophila Alk ligand Jeb resulted in increased levels of Spar protein in the larval CNS. We show that Spar protein is expressed in circadian (clock) neurons, and flies lacking Spar exhibit defects in sleep and circadian activity control. In summary, we report a novel activity regulating neuropeptide precursor gene that is regulated by Alk signaling in the Drosophila CNS.

People form impressions about others during daily social encounters and infer personality traits from others' behaviors. Such trait inference is thought to rely on two universal dimensions: competence and warmth. These two dimensions can be used to construct a ‘social cognitive map’ organizing massive information obtained from social encounters efficiently. Originating from spatial cognition, the neural codes supporting the representation and navigation of spatial cognitive maps have been widely studied. Recent studies suggest similar neural mechanism subserves the map-like architecture in social cognition as well. Here we investigated how spatial codes operate beyond the physical environment and support the representation and navigation of social cognitive map. We designed a social value space defined by two dimensions of competence and warmth. Behaviorally, participants were able to navigate to a learned location from random starting locations in this abstract social space. At the neural level, we identified the representation of distance in the precuneus, fusiform gyrus, and middle occipital gyrus. We also found partial evidence of grid-like representation patterns in the medial prefrontal cortex and entorhinal cortex. Moreover, the intensity of grid-like response scaled with the performance of navigating in social space and social avoidance trait scores. Our findings suggest a neurocognitive mechanism by which social information can be organized into a structured representation, namely cognitive map and its relevance to social well-being.

Bees are important pollinators of agricultural crops, but their populations are at risk when pesticides are used. One of the largest risks bees face is poisoning of floral nectar and pollen by insecticides. Studies of bee detection of neonicotinoids have reported contradictory evidence about whether bees can taste these pesticides in sucrose solutions and hence avoid them. Here, we use an assay for the detection of food aversion combined with single-sensillum electrophysiology to test whether the mouthparts of the buff-tailed bumblebee (
Bombus terrestris
) detect the presence of pesticides in a solution that mimicked the nectar of oilseed rape (
Brassica napus
). Bees did not avoid consuming solutions containing concentrations of imidacloprid, thiamethoxam, clothianidin, or sulfoxaflor spanning six orders of magnitude, even when these solutions contained lethal doses. Only extremely high concentrations of the pesticides altered spiking in gustatory neurons through a slight reduction in firing rate or change in the rate of adaptation. These data provide strong evidence that bumblebees cannot detect or avoid field-relevant concentrations of pesticides using information from their mouthparts. As bees rarely contact floral nectar with other body parts, we predict that they are at high risk of unwittingly consuming pesticides in the nectar of pesticide-treated crops.

Circulating lactate is a fuel source for liver metabolism but may exacerbate metabolic diseases such as nonalcoholic steatohepatitis (NASH). Indeed, haploinsufficiency of lactate transporter monocarboxylate transporter 1 (MCT1) in mice reportedly promotes resistance to hepatic steatosis and inflammation. Here, we used adeno-associated virus (AAV) vectors to deliver thyroxin binding globulin (TBG)-Cre or lecithin-retinol acyltransferase (Lrat)-Cre to MCT1fl/fl mice on a choline-deficient, high-fat NASH diet to deplete hepatocyte or stellate cell MCT1, respectively. Stellate cell MCT1KO (AAV-Lrat-Cre) attenuated liver type 1 collagen protein expression and caused a downward trend in trichrome staining. MCT1 depletion in cultured human LX2 stellate cells also diminished collagen 1 protein expression. Tetra-ethylenglycol-cholesterol (Chol)-conjugated siRNAs, which enter all hepatic cell types, and hepatocyte-selective tri-N-acetyl galactosamine (GN)-conjugated siRNAs were then used to evaluate MCT1 function in a genetically obese NASH mouse model. MCT1 silencing by Chol-siRNA decreased liver collagen 1 levels, while hepatocyte-selective MCT1 depletion by AAV-TBG-Cre or by GN-siRNA unexpectedly increased collagen 1 and total fibrosis without effect on triglyceride accumulation. These findings demonstrate that stellate cell lactate transporter MCT1 significantly contributes to liver fibrosis through increased collagen 1 protein expression in vitro and in vivo, while hepatocyte MCT1 appears not to be an attractive therapeutic target for NASH.

The nucleus incertus (NI), a conserved hindbrain structure implicated in the stress response, arousal, and memory, is a major site for production of the neuropeptide relaxin-3. On the basis of goosecoid homeobox 2 (gsc2) expression, we identified a neuronal cluster that lies adjacent to relaxin 3a (rln3a) neurons in the zebrafish analogue of the NI. To delineate the characteristics of the gsc2 and rln3a NI neurons, we used CRISPR/Cas9 targeted integration to drive gene expression specifically in each neuronal group, and found that they differ in their efferent and afferent connectivity, spontaneous activity, and functional properties. gsc2 and rln3a NI neurons have widely divergent projection patterns and innervate distinct subregions of the midbrain interpeduncular nucleus (IPN). Whereas gsc2 neurons are activated more robustly by electric shock, rln3a neurons exhibit spontaneous fluctuations in calcium signaling and regulate locomotor activity. Our findings define heterogeneous neurons in the NI and provide new tools to probe its diverse functions.

In the process of synaptic formation, neurons must not only adhere to specific principles when selecting synaptic partners but also possess mechanisms to avoid undesirable connections. Yet, the strategies employed to prevent unwarranted associations have remained largely unknown. In our study, we have identified the pivotal role of combinatorial clustered protocadherin gamma (γ-PCDH) expression in orchestrating synaptic connectivity in the mouse neocortex. Through 5' end single-cell sequencing, we unveiled the intricate combinatorial expression patterns of γ-PCDH variable isoforms within neocortical neurons. Furthermore, our whole-cell patch-clamp recordings demonstrated that as the similarity in this combinatorial pattern among neurons increased, their synaptic connectivity decreased. Our findings elucidate a sophisticated molecular mechanism governing the construction of neural networks in the mouse neocortex.
