Investigation of the trade-off between the complexity of the accelerometer bias model and the state estimation accuracy in INS/GNSS integration
Authors: Teodori Gilles , Neuner Hans 
Published: January 2023

Abstract
The integration of Inertial Navigation Systems and Global Navigation Satellite Systems (GNSS) represents the core navigation unit for mobile platforms in open sky environments. A realistic assessment of the accuracy of the navigation solution depends on the accurate modelling of inertial sensor errors. Sensor noise and biases contribute most to short-term navigation errors. For the latter, different models can be used, varying in complexity. This paper investigates how the use of two different models for the accelerometer bias affects the accuracy of the state estimate in an extended Kalman filter. For this purpose, the Allan variance technique is applied to a data sequence from a specific inertial sensor to identify and quantify the underlying noise processes. The estimated noise parameters are used to characterise a bias model for the accelerometers that in addition to the static bias model takes non-white noise processes of the inertial sensor under investigation into account. This detailed accelerometer bias model is compared to a classical modelling approach that only considers static biases. Both approaches are evaluated based on simulation studies for continuous and intermittent GNSS coverages. The results show no significant difference between the two modelling approaches in terms of horizontal position and attitude precision. Furthermore, the correctness of the accelerometer bias estimates is not significantly affected by the modelling approach. All in all, it can be concluded that a detailed bias model of the accelerometers does not outperform the classical modelling approach.

Dysregulation of pain-associated genes in the dorsal root ganglion (DRG) is considered to be a molecular basis of neuropathic pain genesis. Fused in sarcoma (FUS), a DNA/RNA-binding protein, is a critical regulator of gene expression. However, whether it contributes to neuropathic pain is unknown. This study showed that peripheral nerve injury caused by the fourth lumbar (L4) spinal nerve ligation (SNL) or chronic constriction injury (CCI) of the sciatic nerve produced a marked increase in the expression of FUS protein in injured DRG neurons. Blocking this increase through microinjection of the adeno-associated virus (AAV) 5-expressingFusshRNA into the ipsilateral L4 DRG mitigated the SNL-induced nociceptive hypersensitivities in both male and female mice. This microinjection also alleviated the SNL-induced increases in the levels of phosphorylated extracellular signal-regulated kinase 1/2 (p-ERK1/2) and glial fibrillary acidic protein (GFAP) in the ipsilateral L4 dorsal horn. Furthermore, mimicking this increase through microinjection of AAV5 expressing full-lengthFusmRNA into unilateral L3/4 DRGs produced the elevations in the levels of p-ERK1/2 and GFAP in the dorsal horn, enhanced responses to mechanical, heat and cold stimuli, and induced the spontaneous pain on the ipsilateral side of both male and female mice in the absence of SNL. Mechanistically, the increased FUS activated the NF-κB signaling pathway by promoting the translocation of p65 into the nucleus and phosphorylation of p65 in the nucleus from injured DRG neurons. Our results indicate that DRG FUS contributes to neuropathic pain likely through the activation of NF-κB in primary sensory neurons.SIGNIFICANCE STATEMENTIn the present study, we reported that fused in sarcoma (FUS), a DNA/RNA-binding protein, is upregulated in injured dorsal root ganglion (DRG) following peripheral nerve injury. This upregulation is responsible for nerve injury-induced translocation of p65 into the nucleus and phosphorylation of p65 in the nucleus from injured DRG neurons. Because blocking this upregulation alleviates nerve injury-induced nociceptive hypersensitivity, DRG FUS participates in neuropathic pain likely through the activation of NF-κB in primary sensory neurons. FUS may be a potential target for neuropathic pain management.

Published: January 2023

The present study investigated the unpaid overtime experienced by BPO rank-and-file employees and its effect on their career growth, well-being, and labor earnings. How unpaid overtime affects the morale and productivity of employees, and how responsive the organization's policies are to their needs. The researchers have used a phenomenological approach to achieve the study's objectives of identifying the causes and effects of the pressing issues of unpaid overtime experienced by workers. Additionally, the researchers used key informant interviews and focus group discussions in gathering the data among the participants by using an unstructured interview questionnaire to collect information and responses based on their experience with the guide questions. As such, the study found that unpaid overtime detrimentally affects the overall productivity and morale of the employees concerning their work quality in performing their job; unpaid overtime has no direct correlation with career growth; however, it has significantly affected their labor earnings and affects the well-being of the employee, numerous labor violations have been discussed and identified including miscalculation of overtime pay or salary disputes, intimidation from superior to work forcefully with overtime, and decreasing the original incentives to be received to what has been agreed upon and compromised the interest of the employees in rendering unpaid overtime work.

Published: January 2023

AbstractThis review aimed to evaluate the contamination rate of dental unit waterlines (DUWL) with Pseudomonas aeruginosa and Legionella pneumophila in several countries in the Middle East.Literature search was conducted in databases such as PubMed, Scopus, Web of Science, and Google Scholar to gather studies published from the beginning of 2000 to 30th April 2020. Medical Subject Headings (MeSH) terms were; “Legionellosis”; “Legionnaire”, “Legionellosis”, “L. pneumophila”, “dent”, “dental”, “dentistry”, “Dental Unit Waterlines”, “dental water”, “DUWL”, “Middle East”, “P. aeruginosa”, “Iran”, “Turkey”, “Iraq”, and “Jordan”. The search was independently conducted by two of the authors. Data was analyzed using Comprehensive Meta-Analysis software.Almost all studies included in this review reported a high rate of bacterial contamination of DUWL, which exceeded the current standard bacterial contamination level of <200 (CFU) mL−1 recommended by the American Dental Association (ADA). The combined prevalence of L. pneumophila from four countries (Iran, Jordan, Turkey, and Iraq) was 23.5% (95% Cl: 6.5–57.7), and the combined prevalence of P. aeruginosa was reported 21.7% (95% Cl: 7.1–50.1%).This study showed a high bacterial contamination rate of DUWL with opportunistic pathogens. So, it is recommended to prevent biofilm formation in DUWL, some measures should be extended by practical approaches allowing for water quality control and improvement on-site in the dental practices such as mobile filtration units, chlorination and disinfection chemicals.

Resumen. Los enterramientos humanos en el Porce Medio, nordeste del departamento de Antioquia (Colombia), en el periodo denominado desarrollos regionales, son expresiones de la manera como los grupos humanos concebían la muerte. Asimismo, el ritual funerario que incluye la construccióny localización de la tumba en el paisaje es una expresión cultural que legitima la territorialidad de los grupos locales, basada en el hecho de que allí mismo habitan los antepasados.Abstract. Human burials in “El Porce Medio”, in the period called “regional developments” are expressions of the way human groups used to conceive death, but especially, the funeral ritual that includes the construction and location of the tomb in the landscape, it is a cultural expression that legitimizes the territoriality of the local groups, based on an ancient legacy, because in such territory is where their ancestors inhabit.

Haciendo etnología con los caboclos de Quirino: la situación etnográfica como una tríada
Authors: Pacheco de Oliveira João 
Published: January 2023

Resumen. El artículo acomete una revisión crítica de los viajes etnográficos que el etnólogo alemán Curt Unkel —Nimuendaju, según el nombre que le fue adjudicado por los indígenas— realizó a las aldeas ticuna de la selva amazónica brasilera. Se examinan fuentes primarias que documentan lo acontecido en esas experiencias, enmarcado ello en una reflexión sobre el ejercicio etnográfico, el cual debe ser comprendido a partir de las interacciones complejas que lo constituyen y que con creces superan la clásica dualidad investigador-investigado. En el caso de Nimuendaju, su aproximación a lo indígena se vio atravesada por los intereses, valoraciones y perspectivas del Estado o de los jefes de la explotación cauchera, estos últimos convencidos de que la selva no estaba habitada por “indios” sino por “caboclos” que pertenecían a algún barracón. Abstract. The article attempts a critical review of the ethnographic journeys of the German ethnologist, Curt Unkel —Nimuendaju, the name the indigenous peoples attached to him—, among the Tikuna of the Brazilian Amazonian jungle. The article examines primary sources that document the objectives of these experiences, framing them in a reflection regarding the ethnographic exercise which should be understood from the complex interactions that comprise it and from which we should transcend the classic duality investigator/investigated. In the case of Nimuendaju, his approximation to the indigenous question was crossed with state and rubber baron interests, values, and perspectives, the latter of whom were convinced that the jungle was not inhabited by “indios” rather “caboclos” that belonged to algún barracón.
Local magnitude scale and seismicity rate for Tanzania, East Africa
Authors: Langston Charles A. , Brazier Richard , Nyblade Andrew A. , Owens Thomas J. 
Published: January 2023

Abstract
A local magnitude scale is developed for Tanzania, East Africa, using data collected by the 1994/1995 Tanzania Broadband Seismic Experiment. The waveform data from 1189 local and regional earthquakes located within East Africa were corrected for instrument response and convolved with the nominal Wood-Anderson torsion seismograph response appropriate for the original definition of local magnitude. A total of 24,710 maximum S-wave amplitudes were incorporated into an iterative regression for individual event local magnitudes, 38 horizontal component station factors, and 2 linear distance-dependent factors in the log A0 term of the equation for ML. The resulting distance correction, log A0, is given by -log A0 = 0.776 log(r/17) + 0.000902(r − 17) + 2.0, where r is hypocentral distance in kilometers. This distance correction yields much less ground-motion attenuation than observed for southern California and is similar to that observed for local S waves and regional Lg waves propagating in eastern North America. Normalizing the distance correction using the standard constraint of 1-mm ground motion at 100 km for a magnitude 3.0 earthquake results in a bias of nearly half of a magnitude unit between mb and ML, with ML being larger. Normalizing using the constraint of 10 mm of motion at 17 km for ML 3.0 removes the bias in magnitude measures and indicates that structure within Tanzania is relatively high Q. The seismicity rate of Tanzania for 1994/1995 was examined using the Gutenberg-Richter seismicity distribution and is seen to follow the relation log N = 4.63 − 0.84 ML, where N is the number of earthquakes per year of local magnitude ML or greater. The catalog of events used in this study is seen to be complete to magnitude 2 to 2.5.
An indication of time-dependent seismic behavior—An assessment of paleoseismic evidence from the Arava Fault, Israel
Authors: Leonard Gideon , Steinberg David M. , Rabinowitz Nitzan 
Published: January 2023

AbstractWe discuss the implications of 56 kyr of paleoseismic data from a fault on the southern segment of the Arava Fault system in Israel. At least nine events are evident, beginning 37 ka. We study in detail the frequency-magnitude relation for the fault and develop a Bayesian analysis to compare the characteristic earthquake (CE) model and the Gutenberg-Richter (GR) model. Our analysis leads to the conclusion that there was a change in seismic behavior at about 14 ka. From ∼37 ka to ∼14 ka, the seismic activity is best described by the CE model. From ∼14 ka to the present, there is no strong indication favoring one model over the other; the earthquake record is somewhat more consistent with the classical GR equation than with the CE model. If one does assume that the CE model is appropriate for the younger episode, then there is evidence of a change in the characteristic magnitude. Thus, there is evidence of a change in earthquake behavior on the fault segment ∼14 ka.
Source parameters of injection-induced microearthquakes at 9 km depth at the KTB Deep Drilling site, Germany

Published: January 2023

Abstract
A fluid injection-induced seismicity experiment was undertaken in the KTB (German Continental Deep Drilling Program) main borehole at 9 km depth. Several hundred microearthquakes were recorded by a three-component geophone at 4 km depth in the pilot hole of the KTB about 200 m west of the main hole. More than 100 of these events were also recorded with good signal-to-noise ratio by a 73-element temporary network at the surface.
Several different clusters of microearthquakes with distinct waveforms were defined. Compound fault-plane solutions for the two most prominent clusters of seismic events were determined: a strike-slip mechanism for cluster 1 at an average depth of about 8.9 km and a strike-slip/reverse mechanism for cluster 4 (with the “main” ML = 1.2 event) at an average depth of 8.6 km. For both fault-plane solutions, the P axis is subhorizontal and oriented NNW-SSE, similar to the N160°E direction of maximum horizontal stress observed in the well bore. Both clusters were analyzed using an empirical Green's function method to derive the relative source time function (RSTF). Azimuthal variations of the RSTF were used to determine rupture directions and velocities. By combining the information about rupture directions with fault-plane solutions, it was possible to identify the active fault planes (NE striking nodal planes) for both clusters. Although injection-induced events are supposed to exhibit a dilatational component due to the tensile character of the source, the moment tensor inversion for both microearthquake clusters resulted in a double-couple contribution of about 90% and P axes similar to the direction of maximum horizontal stress observed in the borehole. The isotropic components of the moment tensors are insignificant due to the size of the location uncertainties.
From records of the sensor at 4 km depth, we found seismic moments of the microearthquakes ranging from 107 to 1011 N-m. The spectra were corrected for Q [Q(f) = 420 f0.5 for P, and Q(f) = 230 f0.5 for S-waves, which were determined assuming an ω2 model]. Following Brune (1970, 1971), we found source radii between 12 and 28 m and stress drops between 0.01 and 6 MPa. The average ratio of S- to P-wave energy was determined as 14.2. Our relation between seismic moment and ML is log M0 = 1.01 ML + 9.68, and between energy and seismic moment, log E = 2.0 log M0 - 15.35. These seismic scaling relations suggest that stress drop increases with seismic moment for this data set. However, it cannot be precluded that our data, covering only somewhat more than three orders of magnitude, fall in a larger trend of constant-stress-drop scaling over many orders of magnitude due to the large scatter observed over several orders of magnitude.
