The Organization of Lexicons: a Cross-Linguistic Analysis of Monosyllabic Words
Lexicons utilize a fraction of licit structures. Different theories predict either that lexicons prioritize contrastiveness or structural economy. Study 1 finds that the monosyllabic lexicon of Mandarin is no more distinctive than a randomly sampled baseline using the phonological inventory. Study 2 finds that the lexicons of Mandarin and American English have fewer phonotactically complex words than the random baseline: Words tend not to have multiple low-probability components. This suggests that phonological constraints can have superadditive penalties for combined violations, consistent with e.g. Albright (ms.)
Effect of the Steam Activation Thermal Treatment on the Microstructure of Continuous TiO 2
The continuous TiO2 fibers have been synthesized by the sol-gel method using the polymer of titanate as the precursor solution. The as-synthesized samples were characterized using XRD, SEM, and HR-TEM analysis methods. The grain growth kinetics was primarily investigated. The results demonstrated that the average diameters of the fibers were in the range of 20–30 μm, the crystal phase of the synthesized TiO2 fiber was transformed from anasate to rutile, and the crystal size became bigger with increasing the temperature using steam activation. The growth exponent and the constant of growth rate of the rutile crystal phase at 500°C were 4 and 2.55×106 nm/h, respectively. The activation energies of crystalline growth during 500°C~700°C and 700°C~800°C were 38.62 kJ/mol and 143.91 kJ/mol, respectively
Maxillary reconstruction using rectus femoris muscle flap and sagittal mandibular ramus/coronoid process graft pedicled with temporalis muscle
Maxillary reconstruction using various pedicled and free-tissue transfer techniques with bone graft or without bone graft has some drawbacks. In this study, we demonstrate maxillary reconstruction using femoris rectus muscle flap and sagittal mandibular ramus/coronoid process graft pedicled with temporalis muscle through the modified lateral lip-submandibular approach. Nine patients suffering from maxillary defects secondary to maxillary cancer ablation, who underwent maxillary reconstruction using rectus femoris muscle flap and sagittal mandibular ramus/coronoid process graft pedicled with temporalis muscle, were enrolled into this study between November 2015 and August 2017. All patients who underwent the maxillary reconstruction using femoris rectus muscle flap and sagittal mandibular ramus/coronoid process graft pedicled with temporalis muscle presented satisfactory postoperative function, with adequate mouth opening, optimal esthetic outcome and no restrictions on the diet. Every rectus femoris muscle flaps mucosalized well within five weeks. No donor site functional impairment or complications were observed. The technique is a feasible and acceptable technique for the maxillary reconstructions. It is safe, quick and simple to harvest. It also presents an optimal esthetic and satisfactory functional outcome with the advantage of low morbidity of the donor site. Combined with the three-dimension reconstruction, this technique can improve the postoperative outcomes

The stability of segmental properties across genre and corpus types in low-resource languages
Are written corpora useful for phonological research? Word frequency lists for low-resource languages have become ubiquitous in recent years (Scannell, 2007). For many languages there is direct correspondence between their written forms and their alphabets, but it is not clear whether written corpora can adequately represent language use. We use 15 low-resource languages and compare several information-theoretic properties across three corpus types. We show that despite differences in origin and genre, estimates in one corpus are highly correlated with estimates in other corpora
TOTA: Fully Homomorphic Encryption with Smaller Parameters and Stronger Security
We present fully homomorphic encryption schemes for fixed-point arithmetic with fixed precision.
Our scheme achieves - security and uses ring with dimension or less.
Our techniques could also be extended to construct fully homomorphic encryption schemes for approximate numbers with - security.
The bootstrapping process of our - scheme preserves about 39-bit precision with ring dimension , which is the first construction that preserves high precision while keeping the parameters small.
The core technique in this paper is a new and efficient functional bootstrapping algorithm that avoids the negacyclicity constraint of the evaluated functions, which enables us to extract bits blocks homomorphically. This new functional bootstrapping algorithm could be applied to BFV and TFHE schemes as well, and is of independent interest
Poor-prognosis disclosure preference in cancer patient-caregiver dyads and its association with their quality of life and perceived stress: a cross-sectional survey in mainland China
Background
This study attempted to examine the discordance between family caregivers and cancer patients in their poor-prognosis disclosure preferences in mainland China and then ascertained the associations between quality of life (QoL), perceived stress, and poor-prognosis disclosure preferences.
Methods
Six hundred fifty-one pairs of inpatients and their matched caregivers (participation rate = 92.2%) were recruited in this cross-sectional survey. A set of paired self-administered questionnaires were completed independently by patient–caregiver dyads.
Results
Fewer family caregivers than cancer patients felt that poor prognosis should be disclosed to patients (61.2% vs. 90.0%, p < 0.001). Patients' positive poor-prognosis disclosure preference was associated with patients' better QoL (p < 0.05) and caregivers' reduced perceived stress levels (p = 0.013). However, caregivers' poor-prognosis disclosure preference correlated only with their own physical state (p = 0.028). Moreover, the caregivers who concurred with patients in positive poor-prognosis disclosure preference were more likely to experience a better QoL (p < 0.05) and lower perceived stress levels (p = 0.048) in the III–IV stage subgroup.
Conclusions
There was a significant discrepancy in poor-prognosis disclosure preference between cancer patients and caregivers in China. The caregivers' preference of concealing poor prognosis from patients was not related to cancer patients' QoL or perceived stress. In addition, caregivers had better QoL and lower stress levels when they held the same positive poor-prognosis disclosure preference as the patients
Wild relatives of pigeonpea in China
Wild relatives play an important role in the genetic improvement
of cultivated crops. Breeders turn their attention to
the wild relatives of crops after unsuccessful search for
some unique trait in the cultivated germplasm. According
to van der Maesen (1986) the genus Cajanus has 32 species.
Of these, the Indian subcontinent harbors 18 species.
ICRISAT has the global responsibility of collection,
maintenance, and evaluation of germplasm of the wild
relatives of pigeonpea. At present a total of 213 accessions,
representing 20 Cajanus species are conserved for use in
the breeding programs
