text: In the present work, we detail a fast and simple solution-based method to
synthesize hexagonal SnSe2 nanoplates (NPLs) and their use to produce crystallographically
textured SnSe2 nanomaterials. We also demonstrate that the same strategy can be
used to produce orthorhombic SnSe nanostructures and nanomaterials. NPLs are grown
through a screw dislocation-driven mechanism. This mechanism typically results
in pyramidal structures, but we demonstrate here that the growth from multiple
dislocations results in flower-like structures. Crystallographically textured
SnSe2 bulk nanomaterials obtained from the hot pressing of these SnSe2 structures
display highly anisotropic charge and heat transport properties and thermoelectric
(TE) figures of merit limited by relatively low electrical conductivities. To
improve this parameter, SnSe2 NPLs are blended here with metal nanoparticles.
The electrical conductivities of the blends are significantly improved with respect
to bare SnSe2 NPLs, what translates into a three-fold increase of the TE Figure
of merit, reaching unprecedented ZT values up to 0.65.

text: 'We consider the MAP-inference problem for graphical models,which is a valued
constraint satisfaction problem defined onreal numbers with a natural summation
operation. We proposea family of relaxations (different from the famous Sherali-Adams
hierarchy), which naturally define lower bounds for itsoptimum. This family always
contains a tight relaxation andwe give an algorithm able to find it and therefore,
solve theinitial non-relaxed NP-hard problem.The relaxations we consider decompose
the original probleminto two non-overlapping parts: an easy LP-tight part and
adifficult one. For the latter part a combinatorial solver must beused. As we
show in our experiments, in a number of applica-tions the second, difficult part
constitutes only a small fractionof the whole problem. This property allows to
significantlyreduce the computational time of the combinatorial solver andtherefore
solve problems which were out of reach before.'

text: 'A Ge–Si core–shell nanowire is used to realize a Josephson field‐effect transistor
with highly transparent contacts to superconducting leads. By changing the electric
field, access to two distinct regimes, not combined before in a single device,
is gained: in the accumulation mode the device is highly transparent and the supercurrent
is carried by multiple subbands, while near depletion, the supercurrent is carried
by single‐particle levels of a strongly coupled quantum dot operating in the few‐hole
regime. These results establish Ge–Si nanowires as an important platform for hybrid
superconductor–semiconductor physics and Majorana fermions.'

text: The problem of private set-intersection (PSI) has been traditionally treated
as an instance of the more general problem of multi-party computation (MPC). Consequently,
in order to argue security, or compose these protocols one has to rely on the
general theory that was developed for the purpose of MPC. The pursuit of efficient
protocols, however, has resulted in designs that exploit properties pertaining
to PSI. In almost all practical applications where a PSI protocol is deployed,
it is expected to be executed multiple times, possibly on related inputs. In this
work we initiate a dedicated study of PSI in the multi-interaction (MI) setting.
In this model a server sets up the common system parameters and executes set-intersection
multiple times with potentially different clients. We discuss a few attacks that
arise when protocols are naïvely composed in this manner and, accordingly, craft
security definitions for the MI setting and study their inter-relation. Finally,
we suggest a set of protocols that are MI-secure, at the same time almost as efficient
as their parent, stand-alone, protocols.

text: Genome amplification and cellular senescence are commonly associated with
pathological processes. While physiological roles for polyploidization and senescence
have been described in mouse development, controversy exists over their significance
in humans. Here, we describe tetraploidization and senescence as phenomena of
normal human placenta development. During pregnancy, placental extravillous trophoblasts
(EVTs) invade the pregnant endometrium, termed decidua, to establish an adapted
microenvironment required for the developing embryo. This process is critically
dependent on continuous cell proliferation and differentiation, which is thought
to follow the classical model of cell cycle arrest prior to terminal differentiation.
Strikingly, flow cytometry and DNAseq revealed that EVT formation is accompanied
with a genome-wide polyploidization, independent of mitotic cycles. DNA replication
in these cells was analysed by a fluorescent cell-cycle indicator reporter system,
cell cycle marker expression and EdU incorporation. Upon invasion into the decidua,
EVTs widely lose their replicative potential and enter a senescent state characterized
by high senescence-associated (SA) β-galactosidase activity, induction of a SA
secretory phenotype as well as typical metabolic alterations. Furthermore, we
show that the shift from endocycle-dependent genome amplification to growth arrest
is disturbed in androgenic complete hydatidiform moles (CHM), a hyperplastic pregnancy
disorder associated with increased risk of developing choriocarinoma. Senescence
is decreased in CHM-EVTs, accompanied by exacerbated endoreduplication and hyperploidy.
We propose induction of cellular senescence as a ploidy-limiting mechanism during
normal human placentation and unravel a link between excessive polyploidization
and reduced senescence in CHM.
