EVALUATION TECHNICAL EXPERTISE AND STRATEGY PERFORMANCE OF LOCAL NGOs IN UGANDA.
Authors: Okello Lawrence R , Okech Benson B
Published: June 2023

This article deepens debates on quality of localization considering that the strength of a self-regulating organization such as local non-governmental organizations (NGOs) should be seen by the extent to which evaluation technical expertise is applied as part of strategy discourse. In this paper, application of evaluation technical expertise was examined based on skill sets including techniques, technology and technical management oversight that are needed to ensure effective tracking of strategy and actions against approved goals and targets are executed. In most developing countries, poor performance of local NGO strategies has in the past been blamed on poor uptake of evaluation technical expertise(skillsets). The main goal of this study was to examine the relationship between evaluation technical expertise and strategy performance of local NGOs in Uganda. The study used a cross sectional study design using mostly quantitative survey methods. The study drew 349 participants comprising of field workers, mid-level staff and executives from local NGO from all parts of Uganda. The study found that there was positive correlation between evaluation technical expertise and the study constructs of fund stability (r=.219**) community satisfaction (r=- 220**) and timelines(r=-.166**). This study concludes that the correlation is positive but the extent to which it influences strategy performance is still weak. The study recommends the use of sub regional peer support mechanisms by NGO forums and voluntary associations coupled with additional incremental annual self-assessment ratings to address the weakness in evaluation technical expertise.

Published: June 2023

Tahap estimasi upaya (Effort Estimation) digunakan sebagai dasar dalam menentukan jumlah waktu dan orang yang terlibat pada suatu proyek perangkat lunak. Terdapat berbagai metode yang sering dipakai antara lain COCOMO, Function Point, dan Use Case Point. Namun, metode-metode ini memiliki kelemahan seperti adanya subyektifitas dalam mengukur kerumitan dan kurangnya pengukuran pada faktor teknis dan lingkungan pengembangan proyek. Penelitian ini berusaha untuk memperbaiki kelemahan tersebut dengan menggunakan metode Advance Use Case Point (AUCP) dengan dengan memasukkan unsur dari End User Development (EUD) ke dalam Use Case Point, dengan demikian memungkinkan pengguna akhir (end user) untuk mengembangkan perangkat lunak dengan lebih mudah dan efisien. Metode AUCP memperhitungkan kerumitan fungsional dan teknis perangkat lunak (EUD_Technical Factors) dan faktor lingkungan (EUD_Environmental Factors) di pengembangan perangkat lunak. Hasil penelitian menunjukkan bahwa metode Advance Use Case Point memberikan hasil estimasi yang lebih akurat dengan MMRE, MMER, MBRE, MIBRE bernilai 0,01 dan MAE serta RMSE bernilai 8,88. Metode AUCP dapat membantu manajer proyek dan pengguna akhir dalam mengoptimalkan penggunaan sumber daya dan menjamin kelancaran proyek pengembangan perangkat lunak. Penggunaan AUCP juga dapat mempercepat proses pengembangan perangkat lunak dan mengurangi biaya pengembangan karena dapat dilakukan oleh pengguna akhir tanpa perlu keterlibatan tim pengembang profesional. Metode AUCP dapat membantu memperluas aksesibilitas pengembangan perangkat lunak ke kalangan yang lebih luas dan meningkatkan partisipasi pengguna akhir dalam pengembangan perangkat lunak.

Published: June 2023

Inventory of goods is one of several important factors in a company, whether engaged in trading or manufacturing. It is important for inventory to be controlled and supervised in the recording and calculation of inventory, this is because inventory can affect financial reporting. If the amount of inventory is too large (overstock), on the other hand, if the inventory is a little, it will have an impact on the lack of inventory (stockout). The purpose of this research is to develop an inventory control system using the moving average method and the development of an Extreme Programming (XP) system. The moving average method in inventory prediction is more effective because this method compares current and previous data. To develop the system, the Extreme Programming (XP) system development method is used. This method has advantages including: fast process, time and cost efficiency, low risk, flexibility and easy to implement. From the test results using black box testing by testing the functionality, the system shows the system has met expectations with a value reaching 100%. Meanwhile, for testing with the DeLone and McLean models which measure the success of information systems, the score reaches 81.37%.

We also explore the BPS/CFT correspondence in eight dimensions based on the q-Cartan matrix formalism.
THE BEHAVIOUR OF CHINESE GOVERNMENT BOND YIELD CURVE BEFORE AND DURING THE COVID-19 PANDEMIC
Authors: Ganchev Alexander
Published: June 2023

The aim of the study is to investigate the behaviour of the Chinese government bond yield curve before and during the COVID-19 pandemic. Its methodology comprises the techniques of time series analysis, correlation analysis and dimensionality reduction. The main empirical results show that in the pandemic period, the behaviour of the Chinese government bond yield curve differs significantly from that before the outbreak of COVID-19. This is evidenced by the weaker correlations among the analysed yields, the presence of anomalies, heterogeneous behaviour and probable arbitrage opportunities at the long-term end of the studied yield curve, as well as the significant changes in the main factors of its dynamics. The research also reveals that prior to the COVID-19 pandemic, portfolios composed of Chinese government bonds could be well protected against interest rate risk even by using traditional parallel shift immunization techniques. However, after the outbreak of the COVID-19 pandemic the use of such techniques would be relatively effective for portfolios of Chinese government bonds with maturities between 1 and 5 years, while portfolios that include Chinese government bonds with maturities greater than 7 years should be either hedged against all the three factors of the yield curve dynamics or be used only for arbitrage strategies.

Authors: Šimelytė Agnė , Tvaronavičienė Manuela
Published: June 2023

The FDI from the Nordic countries dominate in the Baltic Countries. The Nordic companies invest in various business sectors including the industry and high-tech. Nordic countries are one of the leaders in innovation, patent, industry design and trademark registration. Internalization theories state that host countries benefit from the foreign capital due to “know-how”. The technology and knowledge transfer from the foreign capital companies are defined as even driving force for the economic growth. Thus, the aim of the article is to determine the impact of FDI from the Nordic countries on stimulation of innovations in the Baltic Countries and the interlinkages with the economic growth. The article applies, descriptive statistics and correlation-regression modelling. The findings of the research full fills the gaps in internalization and knowledge transfer theories.

Cosmic multimessenger backgrounds include relic diffuse components created in the early universe and contributions from individual sources. Here, we study both type Ia supernovae (SNe Ia) and core-collapse supernovae (CCSNe) contributions to the diffuse neutrino and gamma-ray backgrounds in the MeV regime referred to as DSNB and DSGB respectively. We show that the diffuse SN Ia background is 106 times lower (for

flux at earth in the 19.3–32 MeV regime is 0.36 ν cm−2 s−1. We also find that the DSNB flux in the energy range from 11.3 to 32 MeV varies by +29% with a change in the SFRD model from Madau & Fragos which yielded a minimum predicted flux, to the extragalactic background light reconstruction model (maximum predicted flux). The diffuse SN Ia gamma-ray background and its dependence on the progenitor supernova delay time distribution are also evaluated. Furthermore, we address the origin of the CGB (Cosmic Gamma-ray Background) in the 0.1–7 MeV regime by adding contributions from sources such as SNe Ia, CCSNe, radio-quiet Active Galactic Nuclei, Flat spectrum radio quasars (FSRQs) and Neutron star—neutron star mergers. We find that our modeled background (including uncertainties) matches the observed CGB above 1.0 MeV, but is a factor ≈2 lower than the observed flux in the 0.1–1.0 MeV range, highlighting the need for future MeV missions to establish the CGB spectrum more reliably, and to possibly identify additional sources or even source classes in the underexplored MeV band.
A Comparison of Outflow Properties in AGN Dwarfs versus Star-forming Dwarfs

Published: June 2023

Feedback likely plays a crucial role in resolving discrepancies between observations and theoretical predictions of dwarf galaxy properties. Stellar feedback was once believed to be sufficient to explain these discrepancies, but it has thus far failed to fully reconcile theory and observations. The recent discovery of energetic galaxy-wide outflows in dwarf galaxies hosting active galactic nuclei (AGNs) suggests that AGN feedback may have a larger role in the evolution of dwarf galaxies than previously suspected. In order to assess the relative importance of stellar versus AGN feedback in these galaxies, we perform a detailed Keck/KCWI optical integral field spectroscopic study of a sample of low-redshift star-forming (SF) dwarf galaxies that show outflows in ionized gas in their Sloan Digital Sky Survey spectra. We characterize the outflows and compare them to observations of AGN-driven outflows in dwarfs. We find that SF dwarfs have outflow components that have comparable widths (W
80) to those of outflows in AGN dwarfs, but are much less blueshifted, indicating that SF dwarfs have significantly slower outflows than their AGN counterparts. Outflows in SF dwarfs are spatially resolved and significantly more extended than those in AGN dwarfs. The mass-loss, momentum, and energy rates of star-formation-driven outflows are much lower than those of AGN-driven outflows. Our results indicate that AGN feedback in the form of gas outflows may play an important role in dwarf galaxies and should be considered along with SF feedback in models of dwarf galaxy evolution.
Examining Uranus’ ζ Ring in Voyager 2 Wide-angle Camera Observations: Quantifying the Ring’s Structure in 1986 and Its Modifications Prior to the Year 2007

Published: June 2023

The ζ ring is the innermost component of the Uranian ring system. It is of scientific interest because its morphology changed significantly between the Voyager 2 encounter in 1986 and subsequent Earth-based observations around 2007. It is also of practical interest because some Uranus mission concepts have the spacecraft pass through the inner flank of this ring. Recent reexaminations of the Voyager 2 images have revealed additional information about this ring that provide a more complete picture of the ring’s radial brightness profile and phase function. These data reveal that this ring’s brightness varies with phase angle in a manner similar to other tenuous rings, consistent with it being composed primarily of submillimeter-sized particles. The total cross section of particles within this ring can also be estimated from these data, but translating that number into the actual risk to a spacecraft flying through this region depends on a number of model-dependent parameters. Fortunately, comparisons with Saturn’s G and D rings allows the ζ ring’s particle number density to be compared with regions previously encountered by the Voyager and Cassini spacecraft. Finally, these data indicate that the observed changes in the ζ ring’s structure between 1986 and 2007 are primarily due to a substantial increase in the amount of dust at distances between 38,000 and 40,000 km from Uranus’ center.

Background/Aims: We evaluated the role of next-generation sequencing (NGS)-based disease monitoring for elderly patients diagnosed with acute myeloid leukemia (AML) who received decitabine therapy.Methods: A total of 123 patients aged > 65 years with AML who received decitabine were eligible. We analyzed the dynamics of variant allele frequency (VAF) in 49 available follow-up samples after the fourth cycle of decitabine. The 58.6% VAF clearance (Δ, [VAF at diagnosis − VAF at follow-up] × 100 / VAF at diagnosis) was the optimal cut-off for predicting overall survival (OS).Results: The overall response rate was 34.1% (eight patients with complete remission [CR], six of CR with incomplete hematologic recovery, 22 with partial responses, and six with morphologic leukemia-free status). Responders (n = 42) had significantly better OS compared with non-responders (n = 42) (median, 15.3 months vs. 6.5 months; p < 0.001). Of the 49 patients available for follow-up targeted NGS analysis, 44 had trackable gene mutations. The median OS of patients with ΔVAF ≥ 58.6% (n=24) was significantly better than that of patients with ΔVAF < 58.6% (n = 19) (20.5 months vs. 9.8 months, p = 0.010). Moreover, responders with ΔVAF ≥ 58.6% (n = 20) had a significantly longer median OS compared with responders with VAF < 58.6% (n = 11) (22.5 months vs. 9.8 months, p = 0.004).Conclusions: This study suggested that combining ΔVAF ≥ 58.6%, a molecular response, with morphologic and hematologic responses can more accurately predict OS in elderly AML patients after decitabine therapy.
Nonlinear adaptive control of avian influenza model with slaughter, educational campaigns and treatment
Authors: Kang Ting , Zhang Qimin , Wang Qingyun
Published: June 2023

Avian influenza is an infectious viral disease caused by type A virus, which occurs frequently around the world and causes serious economic losses. Therefore, the adaptive control problem is explored in this paper for an avian influenza model in consideration of slaughtering to poultry, educational campaigns to the susceptible human and treatment to the infected human. First, by analyzing the transmission mechanism of avian influenza, a nonlinear adaptive control problem of avian influenza model is formulated, where some errors between model parameters and real values are allowed. Then, the parameters are estimated by constructing adaptive laws, which can be effectively used to design the applicative controllers to achieve the control goals. Besides, the stability of controlled model is analyzed with the aid of Lyapunov stability theory. Finally, numerical examples are proposed to verify the effectiveness and robustness of the designed controllers.

Published: June 2023

The goal of this study is to develop a novel iterative algorithm for approximating the solutions of the monotone inclusion problem and fixed point problem of a finite family of demimetric mappings in the context of a real Hilbert space. The proposed algorithm is based on the inertial extrapolation step strategy and combines forward-backward and Tseng's methods. We introduce a demimetric operator with respect to $ M $-norm, where $ M $ is a linear, self-adjoint, positive and bounded operator. The algorithm also includes a new step for solving the fixed point problem of demimetric operators with respect to the $ M $-norm. We study the strong convergence behavior of our algorithm. Furthermore, we demonstrate the numerical efficiency of our algorithm with the help of an example. The result given in this paper extends and generalizes various existing results in the literature.

Au départ d’un matériau empirique constitué notamment de focus groupes menés avec des professionnels de l’évaluation des services de prévention communaux et avec des citoyens bruxellois, cet article revient sur certains enjeux de la participation citoyenne à l’évaluation des politiques de sécurité et de prévention en Région bruxelloise. D’une part, la nature même de ces politiques soulève des questions éthiques qui appellent, des vœux des acteurs professionnels, à des garanties procédurales. D’autre part, l’absence de certains profils de la population dans les dispositifs participatifs bruxellois interroge les acteurs professionnels et aboutit à la formulation de pistes, tant par les évaluateurs que par les citoyens rencontrés, pour tendre vers des processus plus inclusifs. Enfin, la production de nouvelles connaissances par la participation des citoyens se trouve également au cœur des enjeux identifiés.
De medios “adecuados” a fines anhelados
Authors: Giles Alejo Joaquín
Published: June 2023

Las normas jurídicas que prohíben discriminar suelen condicionar este mandato a que la diferencia de trato cuestionada no se encuentre justificada. Habrá justificación, entre otros requisitos, cuando la conducta o norma de conducta concernida tenga una finalidad legítima y sea un medio adecuado para lograrla. ¿Qué significa “adecuado” en tal contexto discursivo? En este artículo ofrezco una respuesta que puede resumirse en tres pasos. El primero consiste en elucidar el impreciso vocablo como cierta aportación causal. El segundo consiste en reconstruir el contenido asignado a esta última idea por dos concepciones de la causalidad, la regularista y la probabilística. El tercero consiste en alegar a favor de comprender la exigencia de “adecuación” como una aportación causal probabilística. Luego de avanzar en esos frentes, atenderé a las oportunidades regulativas que se abren con esta última elección respecto de la estrategia, común en el derecho antidiscriminatorio, de requerir una justificación más robusta para determinada clase de casos. Como mostraré, el carácter gradual de la noción de aportación causal probabilística permite formular distintos niveles de “adecuación” que resulten suficientes a los fines justificativos. Respecto de los niveles no básicos se presenta lo que podría resultar un dilema.
The behaviors of the wave functions of small molecules with negative kinetic energies
Authors: Wang Huai-Yu
Published: June 2023

According to relativistic quantum mechanics, particles can be of negative kinetic energies (NKE). The author asserts in his previous works that the NKE substances are dark matters. Some NKE particles, say a pair of NKE electrons, can constitute a stable system by means of the repulsive
interaction between them. In the present work, two simplest three-particle systems are investigated. One consists of two NKE positrons and one NKE proton, called dark hydrogen anion. The other is composed of two NKE protons and one NKE positron, called dark hydrogen molecule cation. They are
so named because the Hamiltonians of them can correspond to those of the hydrogen anion and hydrogen molecule cation. In evaluating the dark hydrogen molecule cation, the famous Born‐Oppenheimer approximation does not apply, i.e., the NKE of the protons cannot be neglected. Without
the NKE, the system cannot be stable. Our study reveals that in a NKE system, the particles with the same kind of electric charge combine tightly. This is to enhance the repulsive Coulomb potential so as to raise the total energy as far as possible. A great amount of NKE particles can compose
a dense and dark macroscopic NKE body. Thus, it is conjectured that some remote dark celestial bodies may be NKE ones other than the well-known black holes. The discrepancies between the black holes and macroscopic NKE bodies are pointed out.
Reflection of light as a mechanical phenomenon applied to the Michelson interferometer with sunlight as a source
Authors: Filipescu Filip Dambi
Published: June 2023

Emission, propagation, and reflection of light are mechanical phenomena; therefore, these phenomena are observed in an inertial frame as in the frame at absolute rest. At Cleveland Laboratory in 1924, Miller performed experiments with a Michelson interferometer employing local sources
and sunlight. The fringe shift is zero in experiments such as the Michelson‐Morley, where the source and mirrors are at rest in Earth's inertial frame, which explains Miller's experiments with local sources. When the source or/and mirrors are in motion in an inertial frame, there is
a fringe shift. The Sun is an inertial frame at relative rest in which its light travels at the speed  c  in any direction, and Earth travels at the orbital speed  v
 . This is the case of Miller's experiments with sunlight for which this article predicts an unobservable fringe shift in the range of     10
− 8     . Thus, the Cleveland Laboratory experiments involving sunlight and local sources are explained. Miller's observed fringe shift of
 0.08   in 1921 and   0.088   in 1925 at Mount Wilson remains unclear, leaving this subject open to
theoretical and experimental challenges.
Einstein's relativity falsified: I. The factor γ can take values larger than √2, which requires a speed of light < c in moving inertial frames
Authors: Ziefle Reiner Georg
Published: June 2023

Considering that an Einstein clock can travel at a speed no greater than c, from the principle of relativity, a kinematic time dilation factor can be derived whose value cannot be greater than   2
  . In fact, however, the kinematic time dilation factor γ can approach an infinite value. This discrepancy demonstrates that the derivation of the kinematic time dilation factor γ in Einstein's special relativity (SR) cannot be
physically justified by the principle of relativity, and that it is not physically possible that the speed of light is constant in any frame of reference. The mathematical method of Einstein's SR, which I refer to as the “mathematical method of relativity,” allows the calculation
of constant physical values from different quantities of any physical unit and is thus scientifically worthless. Accordingly, it is not surprising that it is possible to predict so-called general relativistic phenomena, e.g., the phenomena observed at the binary pulsar PSR B1913 + 16,
just by applying Kepler's second law and simple quantum physical considerations [R. G. Ziefle, Phys. Essays 33, 99 (2020)]. A careful interpretation of interferometer experiments on Earth clearly shows that there is in fact no need for artificial time acceleration by length contraction.
However, today's physicists seem to be lost in mathematics. The aim of this paper is to contribute to a physical theory of relativity that does not require mathematical tricks, such as time acceleration (length contraction), space-time curvature, and other mathematical tricks that follow from
Einstein's mathematical methods and uphold the illusion that the belief in a constant speed of light c in any frame of reference is physically justified.
Are Perceptions About Government and Social Media Providers Related to Protection Motivation Online?
Authors: Vrhovec Simon , Fujs Damjan
Published: June 2023

This study aims to explore the relations between perceptions about government and social media providers, and protection motivation of social media users. A survey was conducted among students at a public university in Slovenia (N=276). The results of PLS-SEM analysis indicate that fear of government intrusions is associated with both perceived threat and privacy concern. This establishes the perceptions about government as important factors related to both privacy concern and threat appraisal according to protection motivation literature. Non-significant relations between trust in internet service provider, and perceived threat and privacy concern indicate that social media users may not consider them as relevant cyberspace actors capable of threatening their privacy on social media. The results also suggest that trust in social media providers moderates the association between privacy concern and protection motivation. Privacy concern appears to be related to protection motivation only if trust in social media provider is high.

This study aims to determine the associated factors and prevalence of Internet addiction among Jubail University College – Male Branch students. Descriptive cross-sectional method was applied. 171 students participated. Self-administered survey questionnaire was the data-gathering instrument. Young's Internet Addiction Test was used to determine the level of internet usage. Factors associated with high internet consumption are accessibility, boredom, isolation, and extreme weather condition. Covid-19 pandemic changed the way respondents consume internet. It also changed the respondents' sleeping pattern and increases the average internet usage per day. Though the internet played a vital role during Covid-19 pandemic, it also increases the dependency of students on it. Higher number of moderate level internet addiction has been found among respondents. Therefore, it is encouraged that JUC should design a program to address the current situation.

Several thousand organized groups, as well as gangs, are dedicated to cybercrime. The potential rewards for cybercrime can be immense, even for relatively simple crimes. The rapid advancement of technology means that cybercrime is constantly evolving, making it difficult to define and predict. While some may believe cybercrime to be the work of individual lone actors, the reality is quite different. Today, there are thousands of groups dedicated to cybercrime, attracted by its potential rewards. The pace of cybercrime globally is increasing rapidly, and resolving cybercrime is often more challenging than traditional crimes. Authorities worldwide receive thousands of complaints daily, and cybercriminals are becoming increasingly innovative, organized, and sophisticated. They work hard to uncover new vulnerabilities and avoid detection while consumers remain unaware of the risks. With the rapid expansion of ICTs, cybercriminals have unique opportunities to exploit, and the full extent of the dangers is still largely unknown.
An Intelligent Detection Approach for Smoking Behavior
Authors: Chong Jiang
Published: June 2023

Smoking in public places not only causes potential harm to the health of oneself and others, but also causes hidden dangers such as fires. Therefore, for health and safety considerations, a detection model is designed based on deep learning for places where smoking is prohibited, such as airports, gas stations, and chemical warehouses, that can quickly detect and warn smoking behavior. In the model, a convolutional neural network is used to process the input frames of the video stream which are captured by the camera. After image feature extraction, feature fusion, target classification and target positioning, the position of the cigarette butt is located, and smoking behavior is determined. Common target detection algorithms are not ideal for small target objects, and the detection speed needs to be improved. A series of designed convolutional neural network modules not only reduce the amount of model calculations, speed up the deduction, and meet real-time requirements, but also improve the detection accuracy of small target objects (cigarette butts).
Accidental discovery of a Tetraodontidae (Sphoeroides marmoratus) within a cuttlefish (Sepia officinalis) bought in a fish shop in Italy: risk assessment associated with the presence of Tetrodotoxin

The discovery of a pufferfish specimen (Tetraodontidae) inside a frozen cuttlefish, purchased by a fishmonger, and caught in the central-east Atlantic (FAO 34) is reported. The consumer, who reported this case to FishLab (Department of Veterinary Sciences, University of Pisa) for investigation, was a student of Veterinary Medicine at the University of Pisa. He recognized the Tetraodontidae because he attended practical lessons on fish morphological identification during the course of food inspection and was aware of the risks to human health linked to the Tetrodotoxin (TTX). In this study, the pufferfish was identified morphologically, using the FAO morphological keys, and molecularly, analyzing two markers, the cytochrome oxidase I (COI) and the cytochrome b genes, by DNA barcoding. The pufferfish was identified morphologically as Sphoeroides spp., and molecularly as Sphoeroides marmoratus using the COI gene (99-100% identity values). Literature reports that S. marmoratus from the eastern Atlantic contains high concentrations of TTX in the gonads and the digestive tract. However, the possible passage of TTX from fish to other organisms linked to contact or ingestion has never been reported. This represents the first case of a potentially toxic pufferfish entering the market inside another organism. The fact that a student observed this occurrence highlights the key role of citizen science in the management of emerging risks.
Approximations of delocalized eta invariants by their finite analogues
Authors: Wang Jinmin , Xie Zhizhang , Yu Guoliang
Published: June 2023

For a given self-adjoint first order elliptic differential operator on a closed smooth manifold, we prove a list of results on when the delocalized eta invariant associated to a regular covering space can be approximated by the delocalized eta invariants associated to finite-sheeted covering spaces. One of our main results is the following. Suppose

M

is a closed smooth spin manifold and

\widetilde{M}

is a

\Gamma

-regular covering space of

M

. Let

\langle \alpha \rangle

be the conjugacy class of a non-identity element

\alpha\in \Gamma

. Suppose

\{\Gamma_i\}

is a sequence of finite-index normal subgroups of

\Gamma

that distinguishes

\langle \alpha \rangle

. Let

\pi_{\Gamma_i}

be the quotient map from

\Gamma

to

\Gamma/\Gamma_i

and

\langle \pi_{\Gamma_i}(\alpha) \rangle

the conjugacy class of

\pi_{\Gamma_i}(\alpha)

in

\Gamma/\Gamma_i

. If the scalar curvature on

M

is everywhere bounded below by a sufficiently large positive number, then the delocalized eta invariant for the Dirac operator of

\widetilde{M}

at the conjugacy class

\langle \alpha \rangle

is equal to the limit of the delocalized eta invariants for the Dirac operators of

M_{\Gamma_i}

at the conjugacy class

\langle \pi_{\Gamma_i}(\alpha) \rangle

, where

M_{\Gamma_i}= \widetilde{M}/\Gamma_i

is the finite-sheeted covering space of

M

determined by

\Gamma_i

. In another main result of the paper, we prove that the limit of the delocalized eta invariants for the Dirac operators of

M_{\Gamma_i}

at the conjugacy class

\langle \pi_{\Gamma_i}(\alpha) \rangle

converges, under the assumption that the rational maximal Baum–Connes conjecture holds for

\Gamma

.
Wasserstein distance and metric trees
Authors: Mathey-Prevot Maxime , Valette Alain
Published: June 2023

We study the Wasserstein (or earthmover) metric on the space

P(X)

of probability measures on a metric space

X

. We show that, if a finite metric space

X

embeds stochastically with distortion

D

in a family of finite metric trees, then

P(X)

embeds bi-Lipschitz into

\ell^1

with distortion

D

. Next, we re-visit the closed formula for the Wasserstein metric on finite metric trees due to Evans–Matsen (2012).We advocate that the right framework for this formula is real trees, and we give two proofs of extensions of this formula: one making the link with Lipschitz-free spaces from Banach space theory, the other one algorithmic (after reduction to finite metric trees).
Spectral gap and strict outerness for actions of locally compact groups on full factors
Authors: Marrakchi Amine , Vaes Stefaan
Published: June 2023

We prove that an outer action of a locally compact group

G

on a full factor

M

is automatically strictly outer, meaning that the relative commutant of

M

in the crossed product is trivial. If moreover the image of

G

in the outer automorphism group Out

M

is closed, we prove that the crossed product remains full. We obtain this result by proving that the inclusion of

M

in the crossed product automatically has a spectral gap property. Such results had only been proven for actions of discrete groups and for actions of compact groups, by using quite different methods in both cases. Even for the canonical free Bogoljubov actions on free group factors or free Araki–Woods factors, these results are new.

Cybersecurity by Agile Design
Authors: Mazzara Bill , Guo Yuanbo
Published: June 2023

ISO/SAE 21434 [1] Final International Standard was released September 2021 to great fanfare and is the most prominent standard in Automotive Cybersecurity. As members of the Joint Working Group (JWG) the authors spent 5 years developing the 84 pages of precise wording acceptable to hundreds of contributors. At the same time the auto industry had been undergoing a metamorphosis probably unmatched in its hundred-year history. A centerpiece of the metamorphosis is the adoption of the Agile development method to meet market demands for time-to-market and flexibility of design. Unfortunately, a strategic decision was made by the JWG to focus ISO/SAE 21434 on the V-Model method.

Agile does not break ISO/SAE 21434. Agile is a framework that can be adapted to suit any process. In the end the goals are the same regardless of development method; security by design must be achieved. This paper will outline the work products of ISO/SAE 21434 and discuss how the work products required by the standard can be achieved using Agile. The application to Agile may require interpreting the standard from another angle, which could involve reordering the sequence of activities and work products, breaking down the acceptable criteria of some work products to allow rapid iterations, and verifications of meta data or intermediate work products. In cybersecurity engineering, Agile has its unique strength compared to the V-model method, as its cyclical nature is better aligned with best practices for Cybersecurity Frameworks.
Passenger Safety Information System

Published: June 2023

These recommendations are to aid the international air transport industry by identifying a standard, minimum amount of safety instructions and procedures that should be provided in the PSIS. Aircraft operators are encouraged to customize the PSIS to their own operations. This document also provides recommendations for:

a

Passenger safety information briefings and associated materials,

b

Demonstration emergency equipment,

c

Ensuring passenger suitability for those seated in exit seats,

d

The standardization of safety briefings for passengers seated at exits who may be responsible for opening exits on transport aircraft during an emergency, and

e

A standardized protective brace position to reduce the severity of injury during severe turbulence, rapid deceleration, or a sudden impact.

In addition, these recommendations pertain to briefings on aircraft on which the cabin crew would conduct the exit seat briefing, and to briefings on aircraft without cabin crew, on which pilots would conduct the briefing.
