Trump Plan for Ukraine Peace Reportedly Includes Territorial Concessions and Military Limits

A 28-point plan reportedly drafted by former US President Donald Trump proposes a resolution to the Ukraine conflict that would involve Kyiv ceding territory to Russia, considerably reducing its military size, and forgoing any future NATO membership. Details of the plan were obtained by Axios and confirmed by ukrainian, US, and sources familiar with the proposal.

According to Axios, the plan would see the United States recognize Crimea, Luhansk, and Donetsk as Russian territory. A “frozen” conflict line would effectively recognize russian control over parts of kherson and Zaporizhzhia regions, while Russia would relinquish control over other territories it currently occupies beyond these five regions.

The proposal calls for Ukrainian forces to withdraw from the portion of the donetsk Oblast they currently hold. This area would then be designated as a neutral, demilitarized buffer zone internationally recognized as belonging to Russia, with a stipulation that Russian forces would not enter it.

A key component of the plan involves a ample reduction in the Ukrainian Armed Forces, limiting its size to 600,000 personnel. Currently, Ukraine’s military numbers between 800,000 and 850,000, a significant increase from the approximately 250,000 soldiers it had prior to the war.

The plan also suggests entrusting the defense of Ukraine to European fighters stationed in poland,while explicitly prohibiting the deployment of NATO troops within Ukraine.

Ukrainian President Volodymyr zelenskyy has acknowledged receiving the text of the plan,stating he intends to discuss it with Trump. However,Ukrainian sources have reportedly described the proposal as “absurd.”

written by Lucas Fernandez โ€“ World Editor

Israel โ€‹Deploys Laser-Based Air โ€ŒDefense System, Claiming a First

TEL AVIV – Israel has announced the operational deployment ofโข a laser-based air defense system capable of intercepting drones and projectiles, marking what officials claim is a world first.The Ministry โขof Defense has not disclosed specificโค details โฃregarding the system’s range โขor capabilities,but confirmed it has been used in limited capacityโ€ earlier this year.

The โ€Œnew technology is being touted asโข a significantly cheaper option to traditional missile-based defense systems. Israeli officialsโค state the cost โ€‹per interception is less than US $5 (Rp. 83,000), compared toโค the tens of thousands of dollars – orโฃ hundreds of millions of rupiahโค – required for eachโ€ missile intercept.This advancement arrives as Israel โคfaces ongoing multi-front security challenges, including sustained projectile attacks since โ€‹the October 7th Hamas incursion which saw 3,000 rockets fired towards Israel.

Defense minister Israel Katz praised the system’s “fast and โฃtargeted interception with marginal costs that combine our existing defense systemโข and changeโค the equation of threats.” While numerous countriesโข are developing directed energy weapons, Israel assertsโข it is โคtheโ€ firstโค to reach full operational status.โ€ The โคannouncement follows Prime Ministerโค Benjamin โ€Netanyahu’s emphasis on achieving security independence amid โ€Œincreasingโค international isolation. However, the laserโฃ system is known to have technical limitations, including an inability to โ€function in cloudy weather.

Coronary Sinus Reducer Efficacy: Meta-Analysis Reveals Smaller Benefits

Coronary Sinus Reduction: New Analysis Suggests Modest Benefits for Refractory Angina

A novel approach to treating severe chest pain – coronary sinus reduction (CSR) using an hourglass-shaped stent – is facing renewed scrutiny. While initial studies hinted at significant relief for patients with refractory angina (chest pain that doesn’t respond to conventional treatments), a new meta-analysis published in JACC: Cardiovascular Interventions suggests the benefits may be less substantial than previously thought.

The analysis, led by Dr. rasha Al-Lamee of Imperial College London,pooled data from three randomized controlled trials encompassing 180 patients,alongside 13 single-arm studies involving 668 individuals. The procedure itself appears safe, boasting a 98.3% success rate. However, a key finding reveals a stark contrast between the results of rigorously controlled trials and earlier, less controlled studies.

Patients did report improvements in angina symptoms in both types of studies. however,the magnitude of improvement was considerably smaller in the randomized controlled trials. Specifically, approximately 26% of patients in the controlled trials experienced at least a one-class improvement in angina severity (according to the Canadian Cardiovascular Society classification), while 17% saw at least a two-class improvement. These figures represent roughly a third of the gains observed in the single-arm studies.

Crucially, the controlled trials failed to demonstrate any objective benefits. Continuous measurements like the Seattle Angina questionnaire showed no significant change, and there was no evidence of improved blood flow to the heart muscle following the procedure.

Dr. Deepak Bhatt, a cardiologist at Mount Sinai in New York City, who penned an accompanying editorial, emphasized the need for more effective treatments for refractory angina patients, who have often fatigued all other options. While CSR holds potential, he cautioned that larger, more definitive trials are essential before widespread adoption. “We need robust,objectively measured evidence to justify the cost of this procedure,” he stated. He pointed to past examples, like percutaneous laser therapy, which initially appeared promising but ultimately proved ineffective in rigorous trials.

Currently approved for use in the UK and Europe, where its adoption is growing, the CSR device is not yet available in the United States. The ongoing COSIRA-II trial, enrolling approximately 380 patients, is expected to provide the conclusive data needed for potential US approval.

Dr. Al-Lamee believes that if COSIRA-II demonstrates clear benefits, the device coudl become a preferred treatment option before more invasive procedures like repeat coronary artery bypass surgery. “Why resort to a high-risk revascularization if a safe and effective option exists?” she proposed.

Dr. Al-Lamee disclosed financial ties to Shockwave Medical, the manufacturer of the CSR device. Dr. Bhatt reported no relevant financial conflicts.

Macquarie University narrows laser linewidth for quantum computing, atomic clocks

Macquarie Laser Breakthrough Shatters Linewidth Limits

New Raman Scattering Technique Achieves Ten Thousand-Fold Narrowing

Scientists at Macquarie University have unveiled a groundbreaking laser purification method, significantly improving spectral purity for critical scientific applications. This novel technique offers unprecedented control over laser frequency, a key factor in fields ranging from quantum computing to advanced sensing.

Raman Scattering Outperforms Brillouin Lasers

The project, detailed in APL Photonics, utilizes stimulated Raman scattering to drastically narrow a laser beam’s linewidth. This advancement surpasses current methods, such as Brillouin lasers, by a substantial margin.

“Our technique uses stimulated Raman scattering, where the laser stimulates much higher frequency vibrations in the material, and is thousands of times more effective at narrowing linewidth,” explained **Richard Mildren** of the MQ Photonics Research Centre. He contrasted this with existing Brillouin lasers, noting, “One current method to narrow laser linewidth uses Brillouin lasers, where sound waves interact with light; but the effect is relatively weak, typically narrowing by only tens to hundreds of times.”

Diamond Crystal Enhances Vibration Damping

The Macquarie teamโ€™s approach leverages the intrinsic properties of diamond crystals. These materials, chosen for their excellent thermal characteristics and stability, facilitate the efficient dissipation of laser phase fluctuations as vibrations.

In their experiments, a laser beam with a linewidth exceeding 10 MHz was directed through a small diamond crystal within a specialized cavity. The Raman scattering process effectively transferred the laser’s inherent phase noise into vibrational energy within the diamond, where it was absorbed in mere trillionths of a second.

The outcome was a dramatic reduction in the laser beam’s linewidth, narrowed to the 1 kHz limit of the detection equipment. This represents a reduction factor greater than 10,000, with potential for even greater improvement.

“Our computer modeling suggests we could narrow laser linewidth by more than 10 million times using variations of the current design,” added Macquarie’s **David Spence**. This enhanced spectral purity could revolutionize fields like atomic clocks and gravitational wave detection.

Future Applications in Quantum Technology

The breakthrough holds significant promise for quantum computing, where precise laser control is paramount. Reducing phase noise is crucial for minimizing errors in quantum computations.

Richard Mildren emphasized the broad applicability of the new method: “We are essentially proposing a new technique for purifying the spectrum of lasers that can be applied to many different types of input lasers.”

The development aligns with a growing need for high-precision optical components. For instance, the accuracy of modern GPS systems relies on atomic clocks that benefit from more stable laser frequencies, with the global market for atomic clocks projected to reach $1.7 billion by 2027 (Fortune Business Insights 2024).

XGIMI MOGO 4 in the test: Clone of the Samsung Freestyle beats original

by Rachel Kim โ€“ Technology Editor
written by Rachel Kim โ€“ Technology Editor

Ein mobiler Beamer mit Akku fรผr jeden Einsatzort? Da ist der Samsung Freestyle no longer unchallenged. The Chinese Xgimi Mogo 4 copies the agile headlight design class and delivers a lot of extras: whether chic ambilight function, mini remote control for on the go or magnetic alternating lens-XGIMI has not been able to be ragged with the equipment. Accordingly, the laser projector Mogo 4 does not argue with a bargain price, but confidently gets into the market with 800 euros. The test shows whether there is real cinema experience for this stick.
Bei der Verarbeitung bleibt Xgimi dem Anspruch treu, keine Billigalternative zu Samsung zu sein, sondern ein Konkurrent auf Augenhรถhe. Der kleine Projektor liegt recht schwer in der Hand und fรผhlt sich wertvoll an. Apple hat das Erfolgsrezept von Minimalismus und Wertigkeit lรคngst vorgelegt, Xgimi ahmt es fast tadellos nach: Schnรถrkelloses Design, stabiles Material und keine fummeligen Kleinteile โ€“ der MoGo 4 ist eine schlichte silberne Alu-Rรถhre, die aus der Verpackung heraus sofort einsetzbar ist. Wรคhrend der MoGo 2 Even as a small block, Xgimi has been setting since then MoGo 3 In addition to more flexibility, on a more flexible concept with swivel joint – unfortunately, also creates a weak point: the projector can now break the leg because of the slim stand. The rotating design ensures that the connections can now be found on the side instead of the back.

Fire TV statt Google TV: Am HDMI-Anschluss des MoGo 4 ermรถglicht Xgimi auch die Nutzung eines Streaming-Sticks.

Anschlรผsse: Nur die wichtigsten

Table of Contents

Wie bei mobilen Beamern รผblich, ist die Anzahl der Anschlรผsse beim MoGo 4 auf das Notwendigste reduziert. Zu finden sind am Xgimi-Projektor folgende Anschlussmรถglichkeiten:

  • USB-C: Serves as a connection for the charging cable of the XGIMI Mogo 4 (with PD 3.0)
  • HDMI: Connection for Blu-ray players, game consoles, PC or receiver
  • USB-A: Connection for hard drives, data sticks or adapter for Ethernet cables

Interessant: The operation of a Fire TV Stick possible-however, this is not necessary for streaming or TV reception on the projector.

Betriebssystem: Smart mit Google TV

Der Xgimi MoGo 4 ist auch ohne Anschluss externer Medien einsatzfรคhig โ€“ denn mit Google TV Is a smart streaming platform including Netflix and TV-Angebot Prepared on the projector. Setup and operation then work as easily as with any smart TV with Google user interface-only in addition to the illuminated remote control, XGIMI also included a compact mini-remote with a clip for the backpack. The Mogo 4 fits three times in one, with loose enough space for a seat ceiling and a thermos bottle. So cables do not have to go into the luggage when it goes out to the outdoor cinema. But how well does that work in practice?

Sieht schrรคg aus: Die automatische Keystone-Korrektur zieht das Bild des Xgimi MoGo 4 auch bei ungรผnstigem Projektionswinkel gerade. Dadurch leidet aber manchmal die Bildqualitรคt.

Handhabung: Outdoor ja, Action nein

Ein Beamer ohne festen Einsatzort hat so einige Probleme zu bewรคltigen: wechselnde Lichtverhรคltnisse, unklare Batterielaufzeit, unfavorable stand and projection surfaces- to name just the most important. The good news: the Mogo 4 masters all of these challenges properly. With the flexible base, the projection is in Full HD From the most impossible angles in it, since the small projector cylinder can turn freely like a search light. What is certain is that the XGIMI projector is fairly firm despite handstand rollover-as long as the surface is not uneven or sloping. If the projector tips around on pebbles, the best automatic image correction is mercilessly overwhelmed. The Mogo 4 is not an indestructible action projector, because the chic projector takes damage quite quickly with careless handling despite solid construction. If the laser projector is not shaken, he immediately finds the projection surface on its own, the picture automatically pulls and puts it sharp.

Xgimi Mogo 4 bei Licht

Keine groรŸe Leuchte: Gerade im Akku-Betrieb reicht es beim Xgimi MoGo 4 nicht fรผr gute Bilder in heller Umgebung.

Photo: computer picture

Ein Beamer in sehr kompaktem Format mit Akku an Bord โ€“ wie viel Platz bleibt in dem schicken Xgimi-Zylinder noch fรผr den eigentlichen Laserprojektor? Kurz: genug, um bei Dunkelheit ein helles und scharfes Bild mit satten Farben zu zaubern. Schwieriger wird es in helleren Umgebungen ohne Stromanschluss, weil der Projektor sehr sparsam mit seinem Akku wirtschaftet. Das Bild wird sofort deutlich dunkler und die Farben verblassen, sobald man das Netzteil zieht. Wer den Stromsparmodus รผberlistet und im Batteriebetrieb volle Leistung aus der silbernen Lichtrรถhre quetscht, sieht dann bei einem Langfilm von zwei Stunden das Ende nicht mehr. Ist ein Leistungsmonster Asked, mobile projectors with a built -in battery are generally not up for debate. For significantly more luminosity, the handy format and operation without a socket are mandatory. The same applies to the tone – although the Mogo 4 from a confined space produces surprisingly large indoor sound. Xgimi has been looking for prominent support for this feat.

Moderne trifft Klassik: Neben dem klassischen Beamer-Modell von Acer sieht der Xgimi Mogo 4 richtig klein aus. Stationรคre Beamer haben dafรผr mehr Leistungskraft an Bord.

Ton: Raumklang von Harman Kardon

Fรผr einen guten Ton pflegen chinesische Hersteller lรคngst internationale Beziehungen: Xgimi demonstriert zusammen mit den New Yorker Sound-Spezialisten von Harman Kardon gelungenes Teamwork. Wo angesichts des kompakten Formats des Beamers eigentlich Platzangst herrscht, entfaltete sich im Praxistest ein respektabler Klang. Wer ein flaches, blechernes Plรคrren wie aus einer billigen Bluetooth-Box erwartet, erlebt sein blaues Wunder: In Filmen sind nicht nur Dialoge angenehm klar, atmosphรคrischer Sound und Effekte werden erstaunlich raumfรผllend abgegeben. Fรผr den Raumklang-Effekt braucht es dann aber auch einen Raum. Beim Outdoorkino sind Abstriche beim Ton vorprogrammiert, denn die insgesamt 12 Watt Leistung der zwei kleinen Lautsprecher verhallen drauรŸen schnell. Einen tiefen Bass stemmt der kleine Beamer sowieso nicht: Als Partylautsprecher taugt der MoGo 4 trotz reinen Musikwiedergabe-Modus also weniger. Sie brauchen Bass? Via Bluetooth, the connection to a mobile loudspeaker with woofers works quickly if it is supposed to thunder properly on the clearing. At home this also works with a soundbar.

HDR-Bild des XGIMI Mogo 4

Da macht man Augen: Tiefen Kontrast, frische Farben und scharfe Konturen liefert der Xgimi MoGo 4 als wahres Chamรคleon unter den mobilen Beamern im Dunkeln โ€“ bei Licht wechselt der Projektor dann seine Farben, und zwar ins Blasse.

Photo: computer picture

Bildoptimierung: HDR mit Einschrรคnkung

Der Xgimi MoGo 4 hat neben der automatischen Korrektur von Bildausrichtung und Schรคrfe noch mehr Tricks fรผr ein besseres Bild im Gepรคck: Mit einer Bewegungsglรคttung (Motion Smoothing) werden Filme mit Zwischenbildern von 30 auf 60 Bilder pro Sekunde aufgestockt โ€“ somit wirken Bewegungen nicht mehr ruckelig. Bei einer maximalen Auflรถsung in Full HD und ohne KI-gestรผtzte Hochrechnung auf UHD (4K) wirkt das Bild bei groรŸen Projektionen aber eher aufgeweicht. Die prรคzise gezeichneten Strukturen, Farbverlรคufe und dynamischen Kontrastverschiebungen hoher HDR-Standards wie Dolby Vision Or HDR10+ are not on board at all. For their wรผrdige Darstellung The Mogo 4 lacks breath anyway. The small projector in the HDR area provides a pleasantly good picture under ideal conditions: on the power supply, in complete darkness and on an undisturbed projection surface with an image of moderate size. Under realistic conditions with battery on the indolence and the residual light, image sharpness, colors and contrasts are significantly weaker. Measured values โ€‹โ€‹of luminosity, contrast and color space cover are generally convincing in the laboratory test – in the application, a completely different picture is then shown depending on the scenario. However, this is still simply impressive because it just comes from a mobile compact beamer. Nobody demands the performance of diesel heating to a hand warmer for the jacket pocket.

Xgimi MoGo 4 vs. Samsung Freestyle: Wer kann es besser?

Einziger Wermutstropfen vorweg: Der Hellste ist der MoGo 4 von Xgimi auch in der getesteten Laser-Variante fรผr 800 Euro bei Weitem nicht. In der Kรถnigsdisziplin Leuchtktraft รผberragt der ambitionierte Chinaklon des Samsung Freestyle das Original trotzdem um eine Nasenlรคnge. Das Gesamtpaket aus China stellt sein Vorbild dann deutlicher in den Schatten: Mit komfortableren Anschlรผssen, besserem Klang, mehr Benutzerfreundlichkeit, Gaming-Tauglichkeit (bis 60 Hertz) und Top-Zubehรถrpaket รผbertrumpft der MoGo 4 den Samsung Freestyle in vielen wichtigen Disziplinen. Auch bei der Preis-Leistung hat Xgimi die Oberhand, da beim Samsung-Beamer der Akku nur gegen Aufpreis dabei ist. Fรผr Weltrekorde bei der Bildqualitรคt reicht es bei beiden Beamern nicht โ€“ doch in dieser Kategorie treten batteriebetriebene Projektoren ohnehin nicht an.

Testfazit: Xgimi MoGo 4 Laser

Der Xgimi MoGo 4 liefert unter den mobilen Beamern mit Akku derzeit das beste Gesamtpaket. Das farblich frische und scharfe Bild in Full HD sieht zwar am Netzteil deutlich besser aus, im weniger hellen Batterie-Modus schafft der smarte Projektor dafรผr รผber zwei Stunden Filmvergnรผgen ohne jedes Kabel. Dazu liefern Lautsprecher von Harman Kardon guten Klang, von dem man aber angesichts der kompakten GrรถรŸe keinen echten Bass verlangen darf. Auch wenn der Xgimi MoGo 4 in der potenteren Laserausfรผhrung kein Schnรคppchen ist, รผberzeugt die Preis-Leistung dank des reichhaltigen Zubehรถrs auf ganzer Linie. Wer einen leichteren Beamer mit abnehmbarem Akku will, entscheidet sich vielleicht doch besser fรผr den Samsung Freestyle. The Ebon if necessary brings significantly more power at light thickness and sound Anker Nebula X1only real mobility is no longer possible.
