30 Years of Non-Maghreb: What next for Algeria-Morocco relations?

30 Years of Non-Maghreb: What next for Algeria-Morocco relations? 10 September 2024 — 2:00PM TO 3:15PM Anonymous (not verified) Online

Experts discuss Algeria-Morocco relations and implications for regional actors.

In 1989, the establishment of the Arab Maghreb Union (UMA) brought a promise of economic integration and strengthening of ties between Algeria, Libya, Mauritania, Morocco and Tunisia for the benefit and prosperity of their societies.

Decades on, very little has been accomplished in developing the Maghreb project, and the region remains one of the least integrated in the world, despite significant social and cultural similarities between member countries. The last time the full UMA leadership met was back in 1994, with August 2024 marking 30 years of closed borders between Algeria and Morocco.

Relations between the two largest Maghreb countries have deteriorated further since 2020 due to disagreements over issues of Western Sahara, and, most recently, the Abraham Accords, with Algeria cutting diplomatic ties with Morocco in 2021.

In this webinar, experts will discuss:

  • Which primary obstacles are hindering Maghreb integration and Algeria-Morocco relations?
  • What are the costs and implications for regional countries?
  • What are the positions of Libya, Tunisia, and Mauritania?
  • What is required for a rapprochement and how can external partners support this?

N-acetylglucosamine drives myelination by triggering oligodendrocyte precursor cell differentiation [Molecular Bases of Disease]

Myelination plays an important role in cognitive development and in demyelinating diseases like multiple sclerosis (MS), where failure of remyelination promotes permanent neuro-axonal damage. Modification of cell surface receptors with branched N-glycans coordinates cell growth and differentiation by controlling glycoprotein clustering, signaling, and endocytosis. GlcNAc is a rate-limiting metabolite for N-glycan branching. Here we report that GlcNAc and N-glycan branching trigger oligodendrogenesis from precursor cells by inhibiting platelet-derived growth factor receptor-α cell endocytosis. Supplying oral GlcNAc to lactating mice drives primary myelination in newborn pups via secretion in breast milk, whereas genetically blocking N-glycan branching markedly inhibits primary myelination. In adult mice with toxin (cuprizone)-induced demyelination, oral GlcNAc prevents neuro-axonal damage by driving myelin repair. In MS patients, endogenous serum GlcNAc levels inversely correlated with imaging measures of demyelination and microstructural damage. Our data identify N-glycan branching and GlcNAc as critical regulators of primary myelination and myelin repair and suggest that oral GlcNAc may be neuroprotective in demyelinating diseases like MS.

Rage Against the Algorithm: the Risks of Overestimating Military Artificial Intelligence

27 August 2020

Yasmin Afina

Research Assistant, International Security Programme
Increasing dependency on artificial intelligence (AI) for military technologies is inevitable and efforts to develop these technologies to use in the battlefield is proceeding apace, however, developers and end-users must ensure the reliability of these technologies, writes Yasmin Afina.

AI holds the potential to replace humans for tactical tasks in military operations beyond current applications such as navigation assistance. For example, in the US, the Defense Advanced Research Projects Agency (DARPA) recently held the final round of its AlphaDogfight Trials where an algorithm controlling a simulated F-16 fighter was pitted against an Air Force pilot in virtual aerial combat. The algorithm won by 5-0. So what does this mean for the future of military operations?

The agency’s deputy director remarked that these tools are now ‘ready for weapons systems designers to be in the toolbox’. At first glance, the dogfight shows that an AI-enabled air combat would provide tremendous military advantage including the lack of survival instincts inherent to humans, the ability to consistently operate with high acceleration stress beyond the limitations of the human body and high targeting precision.

The outcome of these trials, however, does not mean that this technology is ready for deployment in the battlefield. In fact, an array of considerations must be taken into account prior to their deployment and use – namely the ability to adapt in real-life combat situations, physical limitations and legal compliance.

Testing environment versus real-life applications

First, as with all technologies, the performance of an algorithm in its testing environment is bound to differ from real-life applications such as in the case of cluster munitions. For instance, Google Health developed an algorithm to help with diabetic retinopathy screening. While the algorithm’s accuracy rate in the lab was over 90 per cent, it did not perform well out of the lab because the algorithm was used to high-quality scans in its training, it rejected more than a fifth of the real-life scans which were deemed as being below the quality threshold required. As a result, the process ended up being as time-consuming and costly – if not more so – than traditional screening.

Similarly, virtual environments akin to the AlphaDogfight Trials do not reflect the extent of risks, hazards and unpredictability of real-life combat. In the dogfight exercise, for example, the algorithm had full situational awareness and was repeatedly trained to the rules, parameters and limitations of its operating environment. But, in a real-life dynamic and battlefield, the list of variables is long and will inevitably fluctuate: visibility may be poor, extreme weather could affect operations and the performance of aircraft and the behaviour and actions of adversaries will be unpredictable.

Every single eventuality would need to be programmed in line with the commander’s intent in an ever-changing situation or it would drastically affect the performance of algorithms including in target identification and firing precision.

Hardware limitations

Another consideration relates to the limitations of the hardware that AI systems depend on. Algorithms depend on hardware to operate equipment such as sensors and computer systems – each of which are constrained by physical limitations. These can be targeted by an adversary, for example, through electronic interference to disrupt the functioning of the computer systems which the algorithms are operating from.

Hardware may also be affected involuntarily. For instance, a ‘pilotless’ aircraft controlled by an algorithm can indeed undergo higher accelerations, and thus, higher g-force than the human body can endure. However, the aircraft in itself is also subject to physical limitations such as acceleration limits beyond which parts of the aircraft, such as its sensors, may be severely damaged which in turn affects the algorithm’s performance and, ultimately, mission success. It is critical that these physical limitations are factored into the equation when deploying these machines especially when they so heavily rely on sensors.

Legal compliance

Another major, and perhaps the greatest, consideration relates to the ability to rely on machines for legal compliance. The DARPA dogfight exclusively focused on the algorithm’s ability to successfully control the aircraft and counter the adversary, however, nothing indicates its ability to ensure that strikes remain within the boundaries of the law.

In an armed conflict, the deployment and use of such systems in the battlefield are not exempt from international humanitarian law (IHL) and most notably its customary principles of distinction, proportionality and precautions in attack. It would need to be able to differentiate between civilians, combatants and military objectives, calculate whether its attacks will be proportionate against the set military objective and live collateral damage estimates and take the necessary precautions to ensure the attacks remain within the boundaries of the law – including the ability to abort if necessary. This would also require the machine to have the ability to stay within the rules of engagement for that particular operation.

It is therefore critical to incorporate IHL considerations from the conception and throughout the development and testing phases of algorithms to ensure the machines are sufficiently reliable for legal compliance purposes.

It is also important that developers address the 'black box' issue whereby the algorithm’s calculations are so complex that it is impossible for humans to understand how it came to its results. It is not only necessary to address the algorithm’s opacity to improve the algorithm’s performance over time, it is also key for accountability and investigation purposes in cases of incidents and suspected violations of applicable laws.

Reliability, testing and experimentation

Algorithms are becoming increasingly powerful and there is no doubt that they will confer tremendous advantages to the military. Over-hype, however, must be avoided at the expense of the machine’s reliability on the technical front as well as for legal compliance purposes.

The testing and experimentation phases are key during which developers will have the ability to fine-tune the algorithms. Developers must, therefore, be held accountable for ensuring the reliability of machines by incorporating considerations pertaining to performance and accuracy, hardware limitations as well as legal compliance. This could help prevent incidents in real life that result from overestimating of the capabilities of AI in military operations.

Membrane-bound sn-1,2-diacylglycerols explain the dissociation of hepatic insulin resistance from hepatic steatosis in MTTP knockout mice [Research Articles]

Microsomal triglyceride transfer protein (MTTP) deficiency results in a syndrome of hypolipidemia and accelerated NAFLD. Animal models of decreased hepatic MTTP activity have revealed an unexplained dissociation between hepatic steatosis and hepatic insulin resistance. Here, we performed comprehensive metabolic phenotyping of liver-specific MTTP knockout (L-Mttp–/–) mice and age-weight matched wild-type control mice. Young (10–12-week-old) L-Mttp–/– mice exhibited hepatic steatosis and increased DAG content; however, the increase in hepatic DAG content was partitioned to the lipid droplet and was not increased in the plasma membrane. Young L-Mttp–/– mice also manifested normal hepatic insulin sensitivity, as assessed by hyperinsulinemic-euglycemic clamps, no PKC activation, and normal hepatic insulin signaling from the insulin receptor through AKT Ser/Thr kinase. In contrast, aged (10-month-old) L-Mttp–/– mice exhibited glucose intolerance and hepatic insulin resistance along with an increase in hepatic plasma membrane sn-1,2-DAG content and PKC activation. Treatment with a functionally liver-targeted mitochondrial uncoupler protected the aged L-Mttp–/– mice against the development of hepatic steatosis, increased plasma membrane sn-1,2-DAG content, PKC activation, and hepatic insulin resistance. Furthermore, increased hepatic insulin sensitivity in the aged controlled-release mitochondrial protonophore-treated L-Mttp–/– mice was not associated with any reductions in hepatic ceramide content. Taken together, these data demonstrate that differences in the intracellular compartmentation of sn-1,2-DAGs in the lipid droplet versus plasma membrane explains the dissociation of NAFLD/lipid-induced hepatic insulin resistance in young L-Mttp–/– mice as well as the development of lipid-induced hepatic insulin resistance in aged L-Mttp–/– mice.

Methods for Enrichment and Assignment of N-Acetylglucosamine Modification Sites [Review]

O-GlcNAcylation, the addition of a single N-acetylglucosamine residue to serine and threonine residues of cytoplasmic, nuclear, or mitochondrial proteins, is a widespread regulatory post-translational modification. It is involved in response to nutritional status and stress and its dysregulation is associated with diseases ranging from Alzheimer’s to diabetes.  While the modification was first detected over thirty-five years ago, research into the function of O-GlcNAcylation has accelerated dramatically in the last ten years due to the development of new enrichment and mass spectrometry techniques that facilitate its analysis.  This article summarizes methods for O-GlcNAc enrichment, key mass spectrometry instrumentation advancements, particularly those that allow modification site localization, and software tools that allow analysis of data from O-GlcNAc modified peptides.

Webinar: Finding Solutions to Insecurity in Cabo Delgado

Webinar: Finding Solutions to Insecurity in Cabo Delgado 16 June 2020 — 3:00PM TO 4:30PM Anonymous (not verified) 9 June 2020

Since October 2017, armed attacks in Cabo Delgado, Northern Mozambique have increased in intensity and the spread has widened. Over 1,000 people are thought to have died, and an unknown number of homes and public buildings destroyed. Reports suggest that more than 100,000 people have been internally displaced by these attacks that have been attributed to an armed Islamist sect.
Yet very little is known about who the attackers are, what their strategic objectives are and on whose domestic and international support they rely. Developing multi-faceted solutions to this insecurity will require detailed understanding of the drivers of this extremism, its connection to local informal and illicit economic activity, and the social and structural roots of disenfranchisement and disenchantment.
At this online event, the speakers explore the structural causes, drivers and dynamics of the armed attacks in Cabo Delgado, including the regional and international aspects of the situation.
