SINO-RUSSIAN COOPERATION TOWARD REVISIONISM

The increasing strategic cooperation between China and Russia has grown into a major threat to the current global order and U.S. interests in Europe and Asia, particularly in the wake of the Russian invasion of Ukraine in 2022 and the declaration of a “no-limits” partnership between these two revisionist powers. This thesis assesses the potential scope and limitations of the Sino-Russian strategic alignment from a historical perspective and through the lenses of the relevant theories of international relations dealing with alliances and interstate competition. It also examines the key policy options available to the United States and its allies to limit Chinese and Russian attempts to undermine the Liberal International Order (LIO), and to displace the U.S. in Europe and Asia. The thesis finds that the option of driving a “wedge” between Russia and China through détente with Russia is not feasible if President Putin remains in power; similarly, opportunities for selective cooperation with a resurgent China remain limited. Because Russian and Chinese strategic cooperation and aggressive behavior are primarily driven by the internal threat to their authoritarian systems posed by the LIO, the most appropriate response is to contain these regimes with a U.S.-led global coalition of democracies.Major, United States Marine CorpsApproved for public release.

Non-Refoulement in a World of Cooperative Deterrence

Developed states have what might charitably be called a schizophrenic attitude towards international refugee law. Determined to remain formally engaged with refugee law and yet unwavering in their commitment to avoid assuming their fair share of practical responsibilities under that regime, wealthier countries have embraced the politics of non-entrée, comprising efforts to keep refugees away from their territories but without formally resiling from treaty obligations. As the early generation of non-entrée practices — visa controls and carrier sanctions, the establishment of “international zones,” and high seas deterrence — have proved increasingly vulnerable to practical and legal challenges, new forms of non-entrée predicated on interstate cooperation have emerged in which deterrence is carried out by the authorities of the home or a transit state, or at least in their territory. The critical question we address here is whether such cooperation-based mechanisms of non-entrée are — as developed states seem to believe — capable of insulating them from legal liability in ways that the first generation of non-entrée strategies were not. We show that three evolving areas of international law — jurisdiction, shared responsibility, and liability for aiding or assisting — are likely to stymie many if not all of the new forms of non-entrée. Powerful states are thus faced with a trade-off between the efficiency of non-entrée mechanisms and the ability to avoid responsibility under international refugee law. If, as we believe probable, the preference for more rather than less control persists, legal challenges are likely to prove successful. Law will thus be in a position to serve a critical role in provoking a frank conversation about how to replace the duplicitous politics of nonentrée with a system predicated on the meaningful sharing of the burdens and responsibilities of refugee protection around the world

Design and performance of controlled-diffusion stator compared with original double-circular-arc stator

The capabilities of two stators, one with controlled-diffusion (CD) blade sections and one with double-circular-arc (DCA) blade sections, were compared. A CD stator was designed and tested that had the same chord length but half the blades of the DCA stator. The same fan rotor (tip speed, 429 m/sec; pressure ratio, 1.65) was used with each stator row. The design and analysis system is briefly described. The overall stage and rotor performances with each stator are compared, as are selected blade element data. The minimum overall efficiency decrement across the stator was approximately 1 percentage point greater with the CD balde sections than with the DCA blade sections

Consent-Based Humanitarian Intervention: Giving Sovereign Responsibility Back to the Sovereign

The repeated failure of the United Nations Charter regime to respond to humanitarian crises— and to prevent interventions outside the regime—has laid bare a conflict that lies at the heart of modern international law. This failure has revealed that the twin commitments on which the post-World War II international legal system has been built— sovereign rights and sovereign responsibilities— are often deeply at odds. The response of scholars to this tension has often been to choose sides in the fight. Scholars who place greater value on human rights than state sovereignty have sought to craft exceptions to the prohibition on the use or threat of force. Those who place greater value on sovereignty (and, they would argue, democratic rule of law), have rejected any humanitarian intervention not authorized by the Security Council as illegal and on occasion have portrayed the human rights movement as “anti-sovereigntist” and even “antidemocratic.” In this Article, we offer another way forward— one that aims to respect sovereign rights while helping states meet their sovereign responsibilities and thereby alleviate the tension between the twin commitments of the modern international legal system. Rather than seek to craft an exception to state sovereignty to meet humanitarian aims, we argue for empowering states to meet their sovereign responsibility through what we call “consent-based intervention.

Magnetostriction of ternary Fe–Ga–X (X = C,V,Cr,Mn,Co,Rh) alloys

Binary iron-gallium (Galfenol) alloys have large magnetostrictions over a wide temperature range. Single crystal measurements show that additions of 2 at. % or greater of 3d and 4d transition elements with fewer (V, Cr, Mo, Mn) and more (Co, Ni, Rh) valence electrons than Fe, all reduce the saturation magnetostriction. Kawamiya and Adachi [J. Magn. Magn. Mater. 31–34, 145 (1983)] reported that the D03 structure is stabilized by 3dtransition elements with electron∕atom ratios both less than iron and greater than iron. IfD03 ordering decreases the magnetostriction, the maximum magnetostriction should be largest for the (more disordered) binary Fe–Ga alloys as observed. Notably, addition of small amounts of C (0.07, 0.08, and 0.14 at. %) increases the magnetostriction of the slow cooled binary alloy to values comparable to the rapidly quenched alloy. We assume that small atom (C, B, N) additions enter interstitially and inhibit ordering, thus maximizing the magnetostriction without quenching

Returns to Late Aged College Degrees

The benefits of a college education are well documented. However, the majority of existing research focuses on students who matriculate soon after high school graduation. There is little empirical evidence illustrating whether a college degree is similarly beneficial to those already in the workforce, particularly individuals over 50. Nonetheless, the coming years will see the dramatic growth of older individuals, many of whom will continue to be active in the labor force, and policymakers would benefit from effective strategies to improve the labor market outcomes of older individuals. This research proposes to evaluate the labor market outcomes of individuals in Georgia who obtain a bachelor’s degree at age 50 or older by merging state-level individual level labor force (Dpt of Labor) with individual level educational data from the University System of Georgia (USG). Specifically, we explore whether these later-age degrees result in employment opportunities with higher wages and increased retention in the labor force beyond the traditional retirement age of 65 than those who do not attain a bachelor’s degree.  The results will provide policymakers across the United States with information to make informed decisions regarding higher education incentives and policies for older students

The effect of partial substitution of Ge for Ga on the elastic and magnetoelastic properties of Fe–Ga alloys

Both components of the tetragonal magnetoelastic constant b1: the saturation magnetostriction, λγ,2 = (3/2)λ100, and the magnetic-field saturated shear elasticity, c′ = (c11−c12)/2, were investigated over a wide temperature range for the magnetostrictiveFe1−x−yGaxGey alloys, (x+y ≅ 0.125, 0.185, and 0.245; x/y ≅ 1 and 3). The magnetostriction was measured from 77 to 425 K using standard strain gage techniques. Both shear elastic constants (c′ and c44) were measured from 5 to 300 K using resonant ultrasound spectroscopy. Six alloy compositions were prepared to cover three important regions: (I) the disordered solute α-Fe region, (II) a richer solute region containing both disordered and ordered phases, and (III) a rich solute region containing ordered multiphases. Our observations reveal that, when the data is presented versus the total electron/atom (e/a) ratio, the above regions for both the ternary and binary alloys are in almost perfect alignment. Following this analysis, we find that the magnetoelastic coupling, b1, peaks for both the binary and the ternary alloys at e/a ∼ 1.35. The values of c′ as well as of λγ,2 in region I of the ternary alloys, when plotted versus e/a, fall appropriately between the binary limits

Effects of Zn additions to highly magnetoelastic FeGa alloys

Fe1−xMx (M = Ga, Ge, Si, Al, Mo and x ∼ 0.18) alloys offer an extraordinary combination ofmagnetoelasticity and mechanical properties. They are rare-earth-free, can be processed using conventional deformation techniques, have high magnetic permeability, low hysteresis, and low magnetic saturation fields, making them attractive for device applications such as actuators and energy harvesters. Starting with Fe-Ga as a reference and using a rigid-band-filling argument, Zhang et al. predicted that lowering the Fermi level by reducing the total number of electrons could enhance magnetoelasticity. To provide a direct experimental validation for Zhang\u27s hypothesis, elemental additions with lower-than-Ga valence are needed. Of the possible candidates, only Be and Zn have sufficient solubility. Single crystals of bcc Fe-Ga-Zn have beengrown with up to 4.6 at. % Zn in a Bridgman furnace under elevated pressure (15 bars) in order to overcome the high vapor pressure of Zn and obtain homogeneous crystals. Single-crystalmeasurements of magnetostriction and elastic constants allow for the direct comparison of themagnetoelastic coupling constants of Fe-Ga-Zn with those of other magnetoelastic alloys in its class. The partial substitution of Ga with Zn yields values for the magnetoelastic coupling factor, −b 1, comparable to those of the binary Fe-Ga alloy

Drug-Resistance and Population Structure of Plasmodium falciparum Across the Democratic Republic of Congo Using High-Throughput Molecular Inversion Probes

A better understanding of the drivers of the spread of malaria parasites and drug resistance across space and time is needed. These drivers can be elucidated using genetic tools. Here, a novel molecular inversion probe (MIP) panel targeting all major drug-resistance mutations and a set of microsatellites was used to genotype Plasmodium falciparum infections of 552 children from the 2013-2014 Demographic and Health Survey conducted in the Democratic Republic of the Congo (DRC). Microsatellite-based analysis of population structure suggests that parasites within the DRC form a homogeneous population. In contrast, sulfadoxine-resistance markers in dihydropteroate synthase show marked spatial structure with ongoing spread of double and triple mutants compared with 2007. These findings suggest that parasites in the DRC remain panmictic despite rapidly spreading antimalarial-resistance mutations. Moreover, highly multiplexed targeted sequencing using MIPs emerges as a cost-effective method for elucidating pathogen genetics in complex infections in large cohorts
