Four months into the war between Israel and Hamas, the combatants, their allies, and their neighbors are closer than ever to reaching a cease-fire or even a settlement of their disputes--and are also equally close to seeing it spin out of control into a widening regional conflict. They are tracing this thin line between negotiated peace and escalating mayhem along every front of the Middle East's hot spots, which are intensifying, enlarging, and mingling with one another--a fact that makes it harder but also potentially more manageable to douse the flames. On Friday, U.S. combat planes fired 125 precision-guided missiles and drones at 85 targets into seven facilities--command-control and intelligence centers, supply lines and storage sites for rockets, missiles, and drones, as well as other military targets--all run by Iranian-backed militias in Iraq and Syria. The attack was in retaliation to a Jan. 28 drone strike launched by one of those militias in Iraq that killed three U.S. soldiers at a base in northeastern Jordan, near the Iraqi and Syrian borders. Militias had fired 165 drones or missiles at U.S. forces in the region since Hamas' Oct. 7 attack, but this was the first strike that killed Americans.

Former Acting Defense Secretary Chris Miller joined'Fox & Friends' to discuss the latest on the escalation in the Middle East as the U.S. continues to strike Iranian proxies. A drone attack late Sunday evening that struck a military base in eastern Syria, where U.S. troops are stationed, left at least six allied Kurdish soldiers dead, officials said. The attack hit a training ground at al-Omar base in Syria's eastern province of Deir el-Zour, the U.S.-backed, Kurdish-led Syrian Democratic Forces (SDF) said in a statement Monday. According to the statement, the drone attack struck an area where the forces' commando units were being trained. No U.S. troops were killed or injured in the attack, they said.

We present the DURel tool that implements the annotation of semantic proximity between uses of words into an online, open source interface. The tool supports standardized human annotation as well as computational annotation, building on recent advances with Word-in-Context models. Annotator judgments are clustered with automatic graph clustering techniques and visualized for analysis. This allows to measure word senses with simple and intuitive micro-task judgments between use pairs, requiring minimal preparation efforts. The tool offers additional functionalities to compare the agreement between annotators to guarantee the inter-subjectivity of the obtained judgments and to calculate summary statistics giving insights into sense frequency distributions, semantic variation or changes of senses over time.

Joseph Votel discusses tensions in the Middle East and how the Biden administration could respond to a drone attack that killed three U.S. soldiers, on'The Story.' An Iran-backed militant group in Iraq has promised to continue attacks on U.S. troops after three American soldiers were killed by a drone strike in Jordan on Sunday. In a statement released Friday, Harakat al-Nujaba, one of the strongest Iraqi militias, announced that it plans to continue military operations against U.S. forces while allied factions have backed off their attacks after the Biden administration said there will be retaliation. Akram al-Kaabi, the group's leader, called for an end to the Israeli military operations in Gaza and withdrawal of the "American occupation of Iraq," in a statement posted on X. The announcement comes after Kataib Hezbollah, another powerful Iranian-backed Iraqi militia, which is closely monitored by the U.S. government, said on Tuesday that it would "suspend military and security operations against the occupying forces" to avoid embarrassing the Iraqi government.

The United States has approved plans for strikes in Iraq and Syria against multiple targets, including Iranian personnel and facilities, CBS News reported on Thursday, quoting US officials. President Joe Biden said on Tuesday that he had decided how to respond to a drone attack in northeastern Jordan near the Syrian border last Sunday, which killed three US service members and wounded more than 40. Sunday's attack was the first to result in the loss of American lives during the Israel-Hamas war. Here is what's known about the US plans: The US plans to retaliate against the drone attack on the US Tower 22 base near the border between Syria and Jordan by targeting Iranian personnel and facilities inside both countries. The Islamic Resistance in Iraq, believed to comprise multiple groups armed, funded and trained by Iran's Revolutionary Guards Corps, has claimed responsibility for Sunday's strike on the base. But on Wednesday, Kataib Hezbollah, the most powerful element in the force, announced the suspension of hostile operations against US troops.

About three hours later, U.S. forces shot down an armed Houthi drone flying over the Gulf of Aden, Central Command said. About five hours after that, the military destroyed an explosives-laden naval drone that Central Command said was launched toward commercial ships and Navy vessels in the Red Sea. There were no injuries or damage reported in either incident. Finally, around 12:45 p.m., two anti-ship ballistic missiles were launched from Houthi-controlled territory, probably toward a Liberian-flagged, Bermuda-owned cargo ship, M/V Koi, in the Red Sea, Central Command said. The missiles landed harmlessly in the water.

The United States military has carried out new strikes against 10 drones belonging to the Iran-aligned Houthi rebels in Yemen as well as a ground control centre. On Thursday, US forces targeted a "Houthi UAV ground control station and 10 Houthi one-way UAVs" that "presented an imminent threat to merchant vessels and the US Navy ships in the region", the US military's Central Command (CENTCOM) said in a statement referring to unmanned aerial vehicles. "This action will protect freedom of navigation and make international waters safer and more secure for US Navy vessels and merchant vessels," it added. The group said on Wednesday that all US and British warships participating in "aggression" against Yemen are targets, heightening concerns over the escalating tensions in the region as well as the increased disruption to world trade. CENTCOM said earlier that the USS Carney had shot down an antiship ballistic missile fired by the Houthis and downed three Iranian drones less than an hour later.

We introduce an approach for analyzing the responses of dynamical systems to external perturbations that combines score-based generative modeling with the Fluctuation-Dissipation Theorem (FDT). The methodology enables accurate estimation of system responses, especially for systems with non-Gaussian statistics, often encountered in dynamical systems far from equilibrium. Such cases often present limitations for conventional approximate methods. We numerically validate our approach using time-series data from a stochastic partial differential equation where the score function is available analytically. Furthermore, we demonstrate the improved accuracy of our methodology over conventional methods and its potential as a versatile tool for understanding complex dynamical systems. Applications span disciplines from climate science and finance to neuroscience.

Anthropogenic influences have been linked to tropical cyclone (TC) poleward migration, TC extreme precipitation, and an increased proportion of major hurricanes [1, 2, 3, 4]. Understanding past TC trends and variability is critical for projecting future TC impacts on human society considering the changing climate [5]. However, past trends of TC structure/energy remain uncertain due to limited observations; subjective-analyzed and spatiotemporal-heterogeneous "best-track" datasets lead to reduced confidence in the assessed TC repose to climate change [6, 7]. Here, we use deep learning to reconstruct past "observations" and yield an objective global TC wind profile dataset during 1981 to 2020, facilitating a comprehensive examination of TC structure/energy. By training with uniquely labeled data integrating best tracks and numerical model analysis of 2004 to 2018 TCs, our model converts multichannel satellite imagery to a 0-750-km wind profile of axisymmetric surface winds. The model performance is verified to be sufficient for climate studies by comparing it to independent satellite-radar surface winds. Based on the new homogenized dataset, the major TC proportion has increased by ~13% in the past four decades. Moreover, the proportion of extremely high-energy TCs has increased by ~25%, along with an increasing trend (> one standard deviation of the 40-y variability) of the mean total energy of high-energy TCs. Although the warming ocean favors TC intensification, the TC track migration to higher latitudes and altered environments further affect TC structure/energy. This new deep learning method/dataset reveals novel trends regarding TC structure extremes and may help verify simulations/studies regarding TCs in the changing climate.

White House national security spokesman John Kirby reiterated Wednesday that the U.S. will respond after three American soldiers were killed in a drone attack by an Iran-backed proxy group. President Biden on Tuesday blamed Iran for providing weapons to the militant groups that perpetuated the attack and said he had decided how to respond but did not offer further details. But with no public action in the days since the attack, a reporter asked Kirby whether the White House had missed an opportunity to signal resolve. "I think we signal resolve pretty well. And as I said the other day, we'll respond on our own time, on our own schedule, and we'll do that," Kirby said at the daily White House press briefing.
